Anal-vulvar atresia and agenesis of the coccygeal vertebrae is a rare condition that has never been reported before in donkeys, and only a single case in sheep. In this light, we sought to describe the surgical approach and postoperative care of a newborn donkey with this congenital abnormality. A female donkey was treated that was less than 24 hours old, weighing 15 kg, with increased perineal volume and the absence of an anus. The diagnosis was made by clinical examination, which also found an absence of the vulva and coccygeal vertebrae. A surgical approach followed using anoplasty and temporary fixation of a plastic probe, and a urethra attached to the skin. The postoperative period was followed by daily cleansing, antibiotic, anti-inflammatory and analgesic therapy, and removal of the plastic tube at 10 days. The early diagnosis and treatment enabled complete success and the animal’s recovery., Analno-vulvarna atrezija i ageneza kokcigealnih kralježaka rijetko je stanje koje dosad nije opisano u magaraca, naime opisano je samo u jednom slučaju u ovce. Upravo smo zbog toga nastojali opisati kirurški pristup i poslijeoperacijsku njegu u novorođenog puleta s ovom kongenitalnom abnormalnošću. Riječ je o ženki, staroj manje od 24 sata, tjelesne mase 15 kg, s povećanim perinealnim volumenom i bez anusa. Dijagnoza je postavljena na temelju kliničkog pregleda koji je otkrio i odsutnost vulve i kokcigealnih kralježaka. Uslijedio je kirurški zahvat s anoplastikom i privremenim postavljanjem plastične sonde i uretre pričvršćene za kožu. Poslijeoperacijski je period uključio dnevno čišćenje, antibiotičku, protuupalnu i analgetičku terapiju te uklanjanje plastične cijevi nakon deset dana. Rana dijagnoza i liječenje omogućili su potpun uspjeh u oporavku životinje.

The study of the placenta is of great importance, not only in the attempt to understand the etiopathogenesis of various maternal-fetal pathologies, but also in the attempt to understand whether it is possible to find the cause of pathological neonatal outcomes. On the other hand, abnormalities of blood vessel formation, such as angiodysplasias, have been poorly characterised in the literature, and there is a need for more studies investigating the potential impact on the fetus. In this paper, we retrospectively analysed 2063 placentas received at the Department of Pathology of the University of Bari ‘Aldo Moro’, among which we identified 70 placentas affected by angiodysplasia. On these placentas, we carried out histochemical staining with Masson’s Trichrome, orcein-alcian blue, and, subsequently, immunostaining with anti-CD31, CD34, and desmin and actin muscle smoothness antibodies. Finally, we performed a morphometric analysis on the allantochorionic and truncal vessels and correlated the results with neonatal outcomes. We studied the characteristics of the angiodysplasias in detail, dividing the patients into two classes (A and B) according to the morphology and histochemical characteristics of the affected vessels; statistical analysis reported a statistically significant association (p < 0.05) between the ratio of maximum thickness to maximum diameter (Tmax/Dmax) and neonatal outcome, with only 30% physiological outcome in the cohort of the placentas affected by angiodysplasia. These results shed light on a rather neglected aspect in the 2015 Amsterdam Classification, as well as in the literature, and provided strong evidence that placental angiodysplasia is predictive of an increased likelihood of the pathological fetal outcome, while other factors remain in the field. Studies with larger case series and guidelines with more attention to these aspects are mandated to further investigate the predictive potential of this pathology.

RESUMO Introdução: A Aplasia Congênita da Cútis (ACC) é uma doença rara caracterizada pela ausência de uma parte da pele ao nascimento, seja em área localizada ou generalizada. A incidência é de 0,1 a cada 100.000 nascimentos, tendo como acometimento principal o couro cabeludo, ocorrendo de forma isolada nesta localização em 60% dos casos. As causas não são claras, mas fatores genéticos, teratógenos (álcool, cocaína, maconha, heroína, misoprostol, metimazol, carbimazol, herpes simples congênito, varicela congênita, etc.), comprometimento da irrigação sanguínea para a pele, trauma, bandas amnióticas e desordens cromossômicas (trissomia do 13) estão associados com as lesões. Relato do caso: Paciente do sexo feminino, nascida de parto vaginal com 36 semanas e três dias, e peso adequado para a idade gestacional. Referenciada ao nosso serviço após sete dias de nascimento, constando ausência total do tegumento cutâneo em ambas as pernas, com acometimento de aproximadamente 17% da superfície corpórea, segundo a tabela de queimados de Lund e Browder. A má formação consistia na ausência total de pele e tecido celular subcutâneo. Face a extensão e localização da lesão, optou-se pelo tratamento por enxerto de pele parcial, permitindo, dessa forma, preencher a totalidade do defeito. Conclusão: Devido à raridade da ACC e ao pequeno número de pacientes nas séries publicadas na literatura, a padronização do tratamento ainda é incipiente e o que existe são recomendações. Ainda são necessários estudos que abordem desde a etiologia da doença até a avaliação dos métodos de tratamento. ABSTRACT Introduction: Aplasia cutis congenita (ACC) is a rare disease characterized by the absence of a part of the skin at birth that may be either localized or widespread. The incidence of this disease is 0.1 per 100,000 births. It mainly involves the scalp alone in 60% of the cases. The causes are unclear; however, genetic factors, teratogens (alcohol, cocaine, marijuana, heroin, misoprostol, methimazole, carbimazole, congenital herpes simplex, congenital varicella, and others), impaired blood supply to the skin, trauma, and amniotic band and chromosomal disorders (trisomy 13) are associated with the wounds. Case report: A female patient was delivered vaginally at 36 weeks 3 days of gestation, with appropriate weight for the gestational age. She was referred to our service after 7 days of birth, presenting total absence of skin integument on both legs, with impairment of approximately 17% of the body surface according to the Lund and Browder chart. The malformation consisted of the total absence of skin and subcutaneous tissue. Given the extent and localization of the wound, treatment with a partial skin graft was elected, thereby filling the totality of the defect. Conclusion: Owing to the rarity of ACC and the small number of patients in the series published in the literature, standardization of treatment is still incipient. Currently, only recommendations are available. Further studies are needed in order to investigate the etiology of the disease and to evaluate treatment methods.

Most genetic diseases affect purebred animals and are inherited as recessive genes. Cranioschisis refers to dysraphism, which occurs in the midline of the skull due to failure to close the cranial symphysis, which can lead to herniation of the meninges filled with cerebrospinal fluid (meningocele), where there is usually a projection of the meningeal tissue. Diagnosis is performed based on clinical examination, characteristic anatomopathological data, and complementary imaging tests. The surgical approach for correction of cranioschisis is the only described as a therapeutic solution and is indicated in cases in which the cranial synthesis defect does not allow for brain protrusion and there is only the occurrence of meningocele, in addition to the absence of severe signs of neurological alteration. This paper reports a case of the use of polymethylmethacrylate (PMMA) plaque to treat cranioschisis associated with meningocele in a Girolando heifer. The surgical opening of the frontonasal sacculation allowed draining a total liquid content of 488 mL, inspection, and suture of the envelope membrane. APMMA plaque, molded to the bone surface and anchored in the adjacent soft tissue, was used to cover the evidenced frontonasal bone opening. Despite the unfavorable prognosis of the disease, the cranioplasty surgery for the treatment of cranioschisis associated with meningocele using PMMA plaque obtained satisfactory results relative to the quality and maintenance of this animal’s life, evaluated at 19 months postoperatively. Resumo A maioria das doenças genéticas acometem animais de raça pura e herdados como genes recessivos.Acraniosquise refere-se à disrafia, que acontece na linha média do crânio pelo não fechamento da sínfise craniana, podendo levar a herniação das meninges repletas de líquido cefalorraquidiano (meningocele), onde geralmente existe projeção do tecido meningeal. O diagnóstico é realizado a partir do exame clínico, dados anatomopatológicos característicos e através da realização de exames complementares de imagem. Como solução terapêutica, a abordagem cirúrgica para correção das craniosquises é a única descrita, e é indicada em casos em que o defeito de síntese craniana não permita a protrusão encefálica e exista a ocorrência apenas da meningocele, além da inexistência de sinais graves de alteração neurológica. O artigo relata um caso de uso de placa de polimetilmetacrilato (PMMA) no tratamento de craniosquise associada à meningocele em uma bezerra Girolando. Instituiu-se a abertura cirúrgica da saculação fronto-nasal, permitindo a drenagem de conteúdo líquido total de 488 mL, inspeção e rafia de membrana envoltória. Para recobrimento da abertura óssea fronto-nasal evidenciada, utilizou-se uma placa de polimetilmetacrilato (PMMA), moldada à superfície óssea e ancorada em tecido mole adjacente. Concluiu-se que, apesar do prognóstico desfavorável da enfermidade, a cirurgia de cranioplastia para tratamento de craniosquise associada à meningocele, com a utilização de placa de PMMA, neste caso, obteve resultados satisfatórios em relação a qualidade e manutenção da vida deste animal, avaliando-se em 19 meses pós-operatório.

As tails are often docked within the first days of life, studies investigating tail malformations and injuries in sheep do not exist thus far. To address this gap in the literature, this research aimed to analyse the occurrence of vertebral anomalies and fractures in the tail within an undocked Merinoland sheep population. At 14 weeks of age, the caudal spines of 216 undocked Merinoland lambs was radiographically examined, and tail length and circumference were measured. Anomalies were documented and statistical correlation and model calculations were performed. The occurrence of block vertebrae was observed in 12.96% and wedged vertebrae in 8.33% of the sample. Of the animals, 59 (27.31%) exhibited at least one vertebral fracture, which were observed in the middle and caudal third of the tail. A significant correlation was found between the occurrence of fractures and tail length (r = 0.168) and number of vertebrae (r = 0.155). Conversely, the presence of block and wedged vertebrae was not significantly correlated with tail length, circumference, or number of vertebrae. Only the sex showed significant differences in the probability of axis deviation. These results emphasize the importance of breeding for short tails to avoid fractures.

Evaluation of the sternum is part of the routine examination of small animal thoracic radiographs. However, descriptions on frequency and type of abnormalities are lacking. This retrospective observational study aimed to describe abnormal radiographic findings of the sternum in a cross-section of client-owned dogs and cats undergoing thoracic radiography between 1 January 2019 and 1 January 2021 for reasons unrelated to diseases of the sternum. The study population consisted of 777 dogs (mean age, 7.3 ± 3.9 years) and 183 cats (mean age, 7.3 ± 5.1 years). Sternal abnormalities were observed in 189/777 (24%) dogs and 53/183 (29%) cats, mostly around the intersternebral cartilages, accounting for 32/80 (40%) dogs and 20/35 (57%) cats. This was followed by an abnormal number of sternal segments (8% dogs, range 3–9 sternebrae; 15% cats, range 7–9 sternebra). Pectus excavatum was observed in 6/777 (0.8%) dogs and 6/183 (3%) cats, and pectus carinatum in 18/777 (2%) dogs and 2/183 (1%) cats. Post-traumatic changes, such as subluxation, were observed in nine dogs (1.1%) and three cats (1.6%). Presumed prostatic carcinoma metastasis and malignant lymphoma were observed in two dogs (0.2%). Incidental radiographic sternal abnormalities are common in cats and dogs but mostly of unknown clinical relevance.

In aquaculture and ornamental industries, copepods are recognized as preferred live feeds for marine fish larvae over commonly used organisms such as Artemia and rotifers. Marine fish larvae fed with copepods show better survival and growth. Despite obvious advantages of copepods as the live feed, their use is still limited owing to low productivity and cost-efficiency when mass cultivated. Copepods from the genus Acartia are good candidates for a live feed because their body size, swimming behavior, and biochemical composition are suitable for many marine fish larvae which have small mouth gapes. In addition, Acartia species produce dormant eggs which can be stored and hatched to feed fish larvae. Acartia steueri Smirnov is widely distributed in the coastal waters of the western Pacific Ocean, and is an essential food source for the larvae of commercially important fish in their natural habitats. Different dietary microalgae affect the egg production rate, hatching success, survival rate, growth rate, and the population growth of copepods. One of the underlying bottlenecks in the intensive cultivation of copepods is fatally low survival rate during their larval stages. Calanoid copepods including genus Acartia feed on live microalgae. In the present study, in order to clarify the favorable dietary microalgae for larvae of Acartia steueri, the nauplii individuals were fed with four mono-microalgal diets and one mixed-microalgal diet to measure their survival rate. The present study conducted two experiments. In the first experiment, the nauplii hatched within 24 hours were individually reared in 6-well plates under three diet conditions (mono-diet of Tetraselmis suecica, Rhodomonas salina and Isochrysis galbana) in April 2019. Survival rate and development stages of the copepods were measured every two days. In the second experiment, the nauplii were reared in 600 mL beakers under three diet conditions (mono-diet of T. suecica, Chaetoceros gracilis, and a mixed diet of T. suecica + C. gracilis at 1:1 carbon ratio) in April 2020. Survival rate and development stages of the copepods were measured at day 10 and day 20 during the incubation duration.In the first experiment, the survival rate at day 20 was 26.8 ± 7.2％ when fed with T. suecica, which was the highest value among the mono-microalgal diet conditions. However, only 0.6％ of individuals fed with T. suecica were developed to the adult stage (copepodid VI). In addition, the malformation at first antennas was observed from the copepodid individuals fed with T. suecica. T. suecica is well known to be rich in amino acids but with poor fatty acid content. These results might suggest that T. suecica is the favorable diet for early developmental stages (i.e. nauplii) of the copepod A. steueri, but has a nutritional problem for the later development stages of life cycle. In the second experiment, the ratio of individuals developed until adult stages was maximized under the mixed diet condition of T. suecica and C. gracilis, and this mixed diet can be considered a favorable diet for A. steueri larvae in the present study.

Scrotal arteriovenous malformations (AVM) are extremely rare, making them difficult and complex to diagnose, and a therapeutic challenge; few cases of this type have been reported in the literature. This article reports the case of a male patient, 12 years old, with congenital AVM and background of treatment with sclerotherapy and embolization: it was decided to perform a surgical resection, which was successful. Angiography is obligatory in arteriolar cases, and it was backed up with surgical AVM treatment, taking into account the great importance of pre-surgical embolization.

Piper glabratum Kunth is a plant traditionally used to treat pain and inflammation in the Mato Grosso do Sul, Brazil. Even pregnant women consume this plant. Toxicology studies of the ethanolic extract from the leaves of P. glabratum (EEPg) could establish the safety of popular use of P. glabratrum. Thus, the effects of the ethanolic extract of leaves of P. glabratum (EEPg) on the reproductive performance and embryofetal development of Swiss mice were evaluated. Pregnant female mice were treated with 100, 1000 and 2000 mg/kg throughout the gestational period by gavage (p.o). The control group received the EEPg vehicle (Tween 80–1%) in the proportion of 0.1 mL/10 g (p.o.). The results demonstrated that EEPg has low maternal toxic potential and does not alter the reproductive performance of females. However, it altered embryofetal development and caused fetal weight reduction (increasing the frequency of small-for-gestational-age fetuses) at the two highest doses. In addition, it interfered with placental weight, placental index and placental efficiency. The frequency of visceral malformations increased by 2.8 times for the lowest dose of EEPg, and skeletal malformations increased by 2.48, 1.89 and 2.11 times for doses of 100, 1000 and 2000 mg/kg of EEPg, respectively. It is noteworthy that 100% of the offspring treated with EEPg showed changes in the ossification process. Thus, it is considered that the EEPg has low maternal toxic potential; it does not alter the reproductive performance of females. However, it is teratogenic and interferes, mainly, in the ossification process, and therefore its use is contraindicated in the gestational period.

Graphical abstract, Highlights • 25H-NBOMe and 25H-NBOH recreational drugs induces abnormal formation in zebrafish embryos. • Biophysical and theoretical studies indicate that these drugs have affinity for the DNA major groove. • The toxicity observed in the zebrafish embryos and DNA interaction may be correlated., Toxicological effects of 25H-NBOMe and 25H-NBOH recreational drugs on zebrafish embryos and larvae at the end of 96 h exposure period were demonstrated. 25H-NBOH and 25H-NBOMe caused high embryo mortality at 80 and 100 µg mL−1, respectively. According to the decrease in the concentration tested, lethality decreased while non-lethal effects were predominant up to 10 and 50 µg mL−1 of 25H-NBOH and 25H-NBOMe, respectively, including spine malformation, egg hatching delay, body malformation, otolith malformation, pericardial edema, and blood clotting. We can disclose that these drugs have an affinity for DNA in vitro using biophysical spectroscopic assays and molecular modeling methods. The experiments demonstrated that 25H-NBOH and 25H-NBOMe bind to the unclassical major groove of ctDNA with a binding constant of 27.00 × 104 M−1 and 5.27 × 104 M−1, respectively. Furthermore, these interactions lead to conformational changes in the DNA structure. Therefore, the results observed in the zebrafish embryos and DNA may be correlated.

The long-awaited progress in digitalisation is generating huge amounts of medical data every day, and manual analysis and targeted, patient-oriented evaluation of this data is becoming increasingly difficult or even infeasible. This state of affairs and the associated, increasingly complex requirements for individualised precision medicine underline the need for modern software solutions and algorithms across the entire healthcare system. The utilisation of state-of-the-art equipment and techniques in almost all areas of medicine over the past few years has now indeed enabled automation processes to enter – at least in part – into routine clinical practice. Such systems utilise a wide variety of artificial intelligence (AI) techniques, the majority of which have been developed to optimise medical image reconstruction, noise reduction, quality assurance, triage, segmentation, computer-aided detection and classification and, as an emerging field of research, radiogenomics. Tasks handled by AI are completed significantly faster and more precisely, clearly demonstrated by now in the annual findings of the ImageNet Large-Scale Visual Recognition Challenge (ILSVCR), first conducted in 2015, with error rates well below those of humans. This review article will discuss the potential capabilities and currently available applications of AI in gynaecological-obstetric diagnostics. The article will focus, in particular, on automated techniques in prenatal sonographic diagnostics.

The present report describes a case of conjoined twins of the cephalo-thoraco-omphalopagus deradelphous type in cats. A feline female was transferred to our veterinary hospital as an emergency for dystocic labor. The stillborn was subjected to radiographic evaluation, and a single skull and two complete distinct vertebral columns were found. Anatomopathological examination revealed that the twins presented the head, chest, and umbilicus as the main points of union and were classified as the cephalo-thoraco-omphalopagus type. In addition, the twins had unique and well-developed faces, which allowed them to be classified as deradelphous. This malformation is rare in domestic animals, and to the best of our knowledge, this type has not been reported in felines. Further studies are warranted on this embryonic alteration, primarily because its etiology remains unknown. RESUMO O presente relato descreve um caso de gêmeos siameses do tipo cefalotoraconfalopago deradelfo em gatos. Uma fêmea felina foi atendida na emergência do hospital veterinário em trabalho de parto distócico. Os natimortos foram encaminhados para avaliação radiográfica e constatou-se que apresentavam um único crânio e duas colunas vertebrais completas e distintas. O exame anatomopatológico evidenciou que os gêmeos possuíam cabeça, tórax e umbigo como principais pontos de união, sendo classificados como cefalotoraconfalopago. Além disso, os gêmeos apresentaram face única e bem desenvolvida, o que permitiu classificá-los como deradelfos. Esse tipo de malformação é raro em animais domésticos, e não foi encontrado nenhum trabalho em felino com a mesma classificação do presente relato. Há necessidade de mais estudos sobre essa alteração embrionária, pois a etiologia do processo ainda não foi esclarecida.

Sulfoxaflor (SFX) is a neonicotinoid insecticide widely used to control pests and poses a risk to non-target organisms. The effects of this insecticide, which is known to have toxic effects on non-target organisms, on aquatic organisms, are not fully known. In this study, the developmental toxicity and behavioral effects of sulfoxaflor insecticide in zebrafish embryos and larvae were investigated. Zebrafish embryo-larvae were exposed to different doses of sulfoxaflor (1, 10, and 50 ppm) for 96 hours, and parameters indicative of developmental toxicity such as survival rate, chorion exit rate, and morphological changes were examined. In addition, the effects of sulfoxaflor on the behavior of zebrafish larvae at the 96th hour were determined by locomotor activity (total distance and speed). Results showed that SFX exposure caused a delay in embryo chorion exit and a significant increase in embryo larvae mortality, especially in the 50 ppm administration group. It was observed that SFX caused different malformations (pericardial edema, yolk sac edema, and spine and tail deformation, small eye formation) depending on the dose. In the behavioral test at 96th hour of SFX exposure, it was observed that the total distance and speed increased significantly in the 50 ppm application group, causing hyperactivity in the larvae. This study will provide data to evaluate the potential toxic effects of sulfoxaflor on aquatic organisms., Sulfoxaflor (SFX), zararlıları kontrol etmek için yaygın olarak kullanılan bir neonikotinoid insektisittir ve hedef olmayan organizmalar için risk oluşturmaktadır. Hedef olmayan canlılar üzerine toksik etkilere sahip olduğu bilinen bu insektisitin sucul canlılardaki etkileri tam olarak bilinmemektedir. Bu çalışmada sulfoxaflor insektisitinin zebra balığı embriyo ve larvalarında gelişimsel toksisitesi ve davranış üzerine etkileri araştırıldı. Zebra balığı embriyo-larvalarına 96 saat boyunca farklı dozlarda (1, 10 ve 50 ppm) sulfoxaflor maruz bırakılmış ve hayatta kalma oranı, koryondan çıkış oranı ve morfolojik değişiklikler gibi gelişimsel toksisite göstergesi olan parametreler incelendi. Ayrıca zebra balığı larvalarında 96.saatte davranış üzerine sulfoxaflorun etkileri locomotor akitive (toplam mesafe ve hız) ile belirlendi. Sonuçlar, SFX maruziyetinin embriyo koryondan çıkışında gecikmeye ve özellikle 50 ppm uygulama grubunda embriyo-larvalarda ölümlerinde önemli bir artışa yol açtığı belirlendi. SFX doza bağlı olarak farklı malformasyonlara (pericardial ödem, besin kesesi ödemi, omurga ve kuyruk deformasyonu, küçük göz oluşumu) neden olduğu gözlemlendi. SFX maruziyeti 96.saatte davranış testinde 50 ppm uygulama grubunda toplam mesafe ve hızın önemli oranda artarak larvalarda hiperaktiviteye sebep olduğu görüldü. Bu çalışma, sulfoxaflorun suda yaşayan organizmalar üzerindeki potansiyel toksik etkilerini değerlendirmek için veri sağlayacaktır.

Objective To report an adolescent with infantile‐onset carnitine palmitoyltransferase 2 (CPT2) deficiency and cerebral malformations and to review the occurrence of brain malformations in CPT2 deficiency. The patient presented clinically at age 5 months with dehydration and hepatomegaly. He also has an unrelated condition, X‐linked nephrogenic diabetes insipidus. He had recurrent rhabdomyolysis but normal psychomotor development. At age 17 years, he developed spontaneous focal seizures. Cerebral magnetic resonance imaging revealed extensive left temporo‐parieto‐occipital polymicrogyria, white matter heterotopias, and schizencephaly. Neuronal migration defects were previously reported in lethal neonatal CPT2 deficiency but not in later‐onset forms. Design and Methods We searched PubMed, Google Scholar, and the bibliographies of the articles found by these searches, for cerebral malformations in CPT2 deficiency. All antenatal, neonatal, infantile, and adult‐onset cases were included. Exclusion criteria included insufficient information about age of clinical onset and lack of confirmation of CPT2 deficiency by enzymatic assay or genetic testing. For each report, we noted the presence of cerebral malformations on brain imaging or pathological examination. Results Of 26 neonatal‐onset CPT2‐deficient patients who met the inclusion criteria, brain malformations were reported in 16 (61.5%). In 19 infantile‐onset cases, brain malformations were not reported, but only 3 of the 19 reports (15.8%) include brain imaging or neuropathology data. In 276 adult‐onset cases, no brain malformations were reported. Conclusion To the best of our knowledge, this is the first report of cerebral malformations in an infantile onset CPT2‐deficient patient. Brain imaging should be considered in patients with CPTII deficiency and neurological manifestations, even in those with later clinical onset.

The risk and potential consequences of mother-to-child transmission of severe acute respiratory syndrome-coronavirus type 2 (SARS-CoV-2) during pregnancy are still a matter of debate. We studied the impact of SARS-CoV-2 infection on 56 complete households, including 27 newborns whose mothers were pregnant when exposed to the virus. Two PCR-confirmed perinatal SARS-CoV-2 transmissions with mild symptoms in affected neonates were recorded. In addition, we observed a severe eye malformation (unilateral microphthalmia, optic nerve hypoplasia, and congenital retinopathy) associated with maternal SARS-CoV-2 infection in weeks 5 and 6 of embryonic development. This embryopathy could not be explained by other infectious agents, genetic factors, drug use, or maternal disease during pregnancy. Eight other women with a history of SARS-CoV-2 infection prior to gestational week 12, however, delivered healthy infants.Conclusion: The repeated occurrence of mother-to-child transmission in our cohort with risks that remain incompletely understood, such as long-term effects and the possibility of an embryopathy, should sensitize researchers and stimulate further studies as well as support COVID-19 vaccination recommendations for pregnant women. Trial registration number: NCT04741412. Date of registration: November 18, 2020 What is Known:•Materno-fetal transmission of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) during pregnancy has rarely been reported so far, but was demonstrated in isolated cases. What is New:•In a study of complete households with documented SARS-CoV-2 infection, including a cohort of pregnant women, we observed perinatal coronavirus transmission at a higher frequency than expected.•We also describe a newborn boy with an eye malformation reminiscent of rubella embryopathy but associated with early gestation SARS-CoV-2 infection of his mother.•A coronavirus-related embryopathy, reported here for the first time, is a finding that requires further investigation.

Introduction. Multiseptate gallbladder is a rare congenital malformation of the gallbladder. Septate gallbladder is a rare congenital anomaly. It is anatomical malformations affecting its shape, size, number, and position. Patients with usually admits to the emergency department with differential symptoms such as right upper abdominal pain, nause and vomiting, and abdominal complaints. The aim of this case report is to present a case diagnosed with multiseptated gallbladder. Case presentation. This case was diagnosed cause of the symptomatic clinic and with abdominal ultrasound such multiseptated gallbladder without stones. The case underwent surgical intervention for cholecystectomy. After the surgery intervention the material was sent for the histopathological diagnosis. Conclusions. We recommend cholecystectomy in such cases due to possible complications in the future. In our case we evidence that the clinical story of patients is determinant for the treatment.

Background: Fenestrations are rare, but well-known, vascular variations of the cerebral arteries. They are mostly incidental, asymptomatic angiographic findings and might precipitate vascular lesions such as AVM, aneurysmal dilatation, or even ischemic symptoms. However, association between arterial fenestration and brain aneurysms has not been clearly established. Objective: To evaluate whether incidence of arterial fenestrations are associated with brain aneurysm development and investigate the prevalence and most-common localizations of arterial fenestrations of the human brain. Design: Case–control study. Setting: All patients examined by CT angiography in University Hospital No. 4 in Lublin from 2009 to 2019. Patients: Each patient showing at least one cerebral aneurysm was included in the case group and each patient without cerebral aneurysm on CT angiography was included in the control group. Measurements: CT angiography examinations were conducted using the standard protocol used in the 1st Department of Radiology, Medical University of Lublin, Poland. The database and statistical research were conducted by use of the Statistica software (ver. 13.3, Tibco Software Inc., Palo Alto, CA, USA). Results: A total of 6545 CTA examinations were included in the study. Most of the aneurysms were located on the MCA: 629 (38.59%), ICA: 466 (28.59%) and AComA: 192 (11.78%). Cerebral arterial fenestration showed a non-statistically significant elevated risk for brain aneurysms in the entire study population (OR: 1.157; 95% CI: 0.826–1.621; p = 0.39). Among 6545 cranial CTA examinations, cerebral vessel fenestration was found in 49 of them, which constituted 0.75%. The most common vascular fenestrations were those located in the ACA (30.61%), BA (30.61%) and AComA (22.45%), while other fenestrations occurred infrequently. There were no significant differences in the age of patients in the individuals with vascular fenestration (p > 0.05). VA fenestration was slightly more common in men (16.67%) than in women (5.41%). However, these differences were not statistically significant (p = 0.216). Limitations: Our study has several limitations, including selection bias regarding examined population. Second, we assume that the total number of fenestrations detected in our study was underestimated due to the limitations of the CT method in comparison to other radiologic modalities. Conclusions: Cerebral arterial fenestrations are rare vascular malformations. The ACA is the most common localization of fenestrations, followed by BA and AComA. Fenestrations of cerebral arteries insignificantly increase the risk of cerebral aneurysm formation. Further prospective studies are necessary to make this association more precise.

Objective: This study aims to determine the acute toxicity of binary insecticide Pyro FTE 472 EC (Chlorpyrifos 400 g/l; Cypermethrin 72 g/l) on the egg and embryo of African catfish Clarias gariepinus. Methodology and Results: The fertilized eggs were exposed to six concentrations (T0: 0; T1: 20; T2: 70; T3: 120; T4: 170 and T5: 220 ppm) of Pyro in troughs placed in aquariums to determine the effects on survival, hatching, and development. The arithmetic method of Karber was used to calculate LC50 values. Results showed that eggs/embryos mortality significantly increased with increasing Pyro concentrations. The 24h-LC50 and 48h-LC50 values of Pyro for eggs/embryos were 102.26 and 90.40 ppm, respectively. Paradoxically, hatching success increased significantly from T1 to T3. Rates of tailless and short-tail embryos and immobility and agglutination of embryos increased with increasing Pyro concentrations. Conclusions and application of findings: The present study revealed that Pyro FTE 472 EC, a binary pesticide used extensively in the fields against insect pests of cotton plants during the flooding period of reproduction of C. gariepinus could harm the development of this specie. A reduction in the quantity of this biocide in the cotton fields is essential in order not to reach the lethal doses for the eggs/embryos of C. gariepinus. This study, first report, indicates thus for biomonitoring the limit values of Pyro in aquatic biotopes to preserve the eggs/embryos of C. gariepinus in particular and of other fish in general.

Bone-anchored hearing aids are devices used in individuals with ear malformations who present some restriction to the use of conventional hearing aids. The verification of subjective assessment measures in users of bone-anchored hearing aids is an important process in rehabilitation. This review will answer the question: What subjective tools are used to assess individuals with malformations and users of bone-anchored hearing aids? Therefore, the objective is to identify the scientific evidence available in gray and non-grey literature to fill this knowledge gap.

Macrodontia is a dental condition where a tooth or group of teeth are abnormally larger than average. Functional and aesthetic discrepancies may arise in affected individuals resulting in lowering the quality of life. It has been noted that macrodontia is associated with several genetic and endocrine abnormalities. Among which, KBG syndrome is a rare genetic disorder characterized by developmental and dental abnormalities. This case report provides a brief overview of the significance of macrodontia, along with presenting a case of KBG syndrome with atypical features in a South African, 16-year-old female. The dental manifestations are often overshadowed by other more conspicuous and complex syndromic features. Recognition of both the clinical and oral changes that occur in KBG syndrome facilitates accurate diagnosis and appropriate management of this condition. The authors highlight the importance for clinicians to be cognizant of the clinical implications of macrodontia.

Due to their low incidence and thus resulting limited diagnostic criteria as well as therapeutic options, rare diseases of the nose, the paranasal sinuses, and the anterior skull base are a significant challenge. The value as of which a disease has to be considered as rare amounts to a maximum of 5 patients per 10 000 people. Within these diseases, however, there are extreme differences. Some rare or orphan diseases like for example the inverted papilloma belong to regularly diagnosed and treated diseases of larger departments of oto-rhino-laryngology whereas other rare diseases and malformations have only been described in less than 100 case reports worldwide. This fact emphasizes the necessity of bundling the available experience of diagnostics and therapy. The present article gives an overview about rare diseases of the nose, the paranasal sinuses, and the anterior skull base from the field of diseases/syndromes of the olfactory system, malformations of the nose and paranasal sinuses, ventilation and functional disorders as well as benign and malignant tumors. The classification and data on diagnostic and therapeutic options were established based on the current literature.Seltene Erkrankungen der Nase, der Nasennebenhöhlen und der vorderen Schädelbasis stellen aufgrund der niedrigen Inzidenz und den daraus resultierend eingeschränkten diagnostischen Kriterien sowie therapeutischen Optionen eine Herausforderung dar. Der Schwellenwert, ab dem eine Erkrankung als selten zu werten ist, liegt bei höchstens 5 Betroffenen pro 10 000 Personen. Innerhalb dieser Erkrankungen gibt es allerdings extreme Schwankungen. So gehören einige seltene Erkrankungen, wie z.B. das invertierte Papillom, zu den regelmäßig diagnostizierten und therapierten Krankheitsbildern einer größeren Klinik für Hals-Nasen-Ohrenheilkunde. Andererseits liegen bei anderen seltenen Erkrankungen und Fehlbildungen weltweit deutlich unter 100 Fallberichte vor, was die Notwendigkeit einer Bündelung der verfügbaren Erfahrung zu Diagnostik und Therapie unterstreicht.Die vorliegende Arbeit gibt eine Übersicht zu seltenen Erkrankungen der Nase, der Nasennebenhöhlen und der vorderen Schädelbasis aus den übergeordneten Bereichen Erkrankungen / Syndrome des olfaktorischen Systems, Fehlbildungen der Nase und Nasennebenhöhlen, Belüftungs- und Funktionsstörungen sowie benigne und maligne Tumore. Die Einordnung sowie Angaben zu Diagnostik und Therapiemöglichkeiten wurden unter Berücksichtigung der aktuellen Literatur erstellt.

This article provides an overview of rare orbital diseases. Congenital malformations, inflammatory diseases, benign and malignant neoplasias are described. Although it represents a relatively small area of the body the orbit contains multiple different tissues. Therefore, a great variety of diseases can be found within the orbital space. That is the reason, why both the completeness and the level of detail in the description of particular diseases must be somewhat limited. Nevertheless, clinical manifestations, important aspects of diagnosis, treatment strategies, and, when specific data are available, the prognosis are described. The authors tried to highlight the most characteristic aspects of the different diseases to describe their relevant aspects in spite of the brevity of the subsections.Dieser Übersichtsartikel stellt eine Zusammenstellung seltener Erkrankungen der Orbita dar. Es werden angeborene Fehlbildungen und strukturelle Läsionen, entzündliche Erkrankungen, gutartige und bösartige epitheliale sowie nicht epitheliale Tumoren erörtert. Da in der Orbita zahlreiche Gewebetypen auf engstem Raum beieinanderliegen, kommen dort besonders viele Erkrankungen vor, sodass der Vollständigkeit und dem Tiefgang bei den einzelnen Abhandlungen natürliche Grenzen gesetzt sind. Die Kapitel beinhalten eine Übersicht über das jeweilige klinische Erscheinungsbild, wichtige Stichpunkte zur Diagnostik, Therapie und gegebenenfalls zur Prognose der Erkrankung. Dabei wurde versucht, die besonders charakteristischen Merkmale der einzelnen Erkrankungen herauszuarbeiten, sodass trotz der kurzen Darstellung die relevanten Aspekte enthalten sind.

Use of endothelin receptor antagonists (ERAs) and riociguat, approved for treatment of pulmonary hypertension (PH), is contraindicated during pregnancy due to reported teratogenicity in animals. We aimed to investigate prescribing of these drugs in girls/women of childbearing age and to explore – as a secondary aim – the occurrence of pregnancies exposed to these drugs. Using the German Pharmacoepidemiological Research Database (GePaRD, claims data from 20% of the German population) we conducted cross-sectional analyses to determine prescribing prevalence of ERAs and riociguat between 2004 and 2019 and to characterize users and prescribing patterns. In a cohort analysis, we assessed the occurrence of pregnancies exposed to these drugs in the critical time window. Overall, we identified 407 women with ≥ 1 dispensation of bosentan between 2004 and 2019; the respective number was 73 for ambrisentan, 182 for macitentan, 31 for sitaxentan, and 63 for riociguat. In nearly all years, more than 50% of the girls/women were ≤ 40 years. Age-standardized prevalence was highest for bosentan (0.04/1000) in 2012 and 2013, followed by macitentan (0.03/1000) in 2018 and 2019. We observed 10 exposed pregnancies: 5 to bosentan, 3 to ambrisentan, and 2 to macitentan. The increased prevalence of macitentan and riociguat from 2014 onwards might reflect changes in PH treatment. Even though PH is a rare disease and pregnancy should be avoided in women with PH, particularly if they use ERAs, we identified pregnancies exposed to ERAs. Multi-database studies will be needed to assess the risk of these drugs on the unborn child.

Background: This study aimed to report a European multi-institutional experience about thoracoscopic management of children with congenital lung malformations. Methods: The records of 102 patients (49 girls and 53 boys) with median age at surgery of 1 year (range 6 months-1.5 years), who underwent thoracoscopic lobectomy in five European Pediatric Surgery units, were retrospectively collected. Indications for surgery included congenital pulmonary airway malformation (CPAM) (n = 47), intra- and extralobar pulmonary sequestration (n = 34), hybrid lesion (CPAM/intralobar sequestration) (n = 2), severe bronchiectasis (n = 9), congenital lobar emphysema (n = 8), and others (n = 2). The condition was asymptomatic in 77/102 (75.5%), whereas symptoms such as recurrent pneumonia and/or respiratory distress were present in 25/102 (24.5%). Results: Surgical procedures included 18 upper, 20 middle, and 64 lower lobe resections. No conversions to open were reported. A 3 mm sealing device and 5 mm stapler were adopted in the last 48/102 patients (47%). The median operative time was 92.2 minutes (range 74-141). The median operative time significantly decreased in patients in whom the vessel division and bronchial sealing were performed using sealing devices (75.5 minutes) compared with suture ligations (118.9 minutes) (P = .001). The median hospital stay was 3.7 days (range 2-6.2). Three/102 patients (2.9%) developed postoperative complications, including air leakage requiring pleural drainage (n = 1) (Clavien IIIb) and respiratory infection (n = 2) (Clavien II). A reoperation was required in one patient with residual pleuropulmonary blastoma (0.9%). All symptomatic patients reported resolution of symptoms postoperatively. Conclusions: Thoracoscopic lobectomy is a safe and effective procedure with excellent cosmetic outcome, in expert hands. Based upon our experience, we strongly recommend surgery in patients with congenital lung malformations by the first year of life, to reduce the risk of infection and make the procedure technically easier, despite the small patients' size. Surgeon's experience and use of miniaturized instruments and sealing devices remain key factors for successful outcome.

Background To establish the normal reference range of fetal thorax by two-dimensional (2D) and three-dimensional (3D) ultrasound VOCAL technique and evaluate the application in diagnosing fetal thoracic malformations. Methods A prospective cross-sectional study was undertaken involving 1077 women who have a normal singleton pregnancy at 13–40 weeks gestational age (GA). 2D ultrasound and 3D ultrasound VOCAL technique were utilized to assess fetal thoracic transverse diameter, thoracic anteroposterior diameter, thoracic circumference, thoracic area, lung volume, thoracic volume and lung-to-thoracic volume ratio. The nomograms of 2D and 3D fetal thoracic measurements were created to GA. 50 cases were randomly selected to calculate intra- and inter-observer reliability and agreement. In addition, the case groups including congenital skeletal dysplasia (SD) (15), congenital diaphragmatic hernia (CDH) (30), pulmonary sequestration (PS) (25) and congenital cystic adenomatoid malformation (CCAM) (36) were assessed by the nomograms and followed up subsequently. Results Both 2D and 3D fetal thoracic parameters increased with GA using a quadratic regression equation. The intra- and inter-observer reliability and agreement of each thoracic parameter were excellent. 2D fetal thoracic parameters could initially evaluate the fetal thoracic development and diagnose the skeletal thoracic deformity, and lung volume, thoracic volume and lung-to-thorax volume ratio were practical to diagnose and differentiate CDH, PS and CCAM. Conclusion We have established the normal fetal thoracic reference range at 13–40 weeks, which has a high value in diagnosing congenital thoracic malformations.

Neuropathologic hallmarks of Huntington Disease (HD) include the progressive neurodegeneration of the striatum and the presence of Huntingtin (HTT) aggregates that result from abnormal polyQ expansion of the HTT gene. Whether the pathogenic trinucleotide repeat expansion of the HTT gene causes neurodevelopmental abnormalities has garnered attention in both murine and human studies; however, documentation of discrete malformations in autopsy brains of HD individuals has yet to be described. We retrospectively searched the New York Brain Bank (discovery cohort) and an independent cohort (validation cohort) to determine whether developmental malformations are more frequently detected in HD versus non-HD brains and to document their neuropathologic features. One-hundred and thirty HD and 1600 non-HD whole brains were included in the discovery cohort and 720 HD and 1989 non-HD half brains were assessed in the validation cohort. Cases with developmental malformations were found at 6.4–8.2 times greater frequency in HD than in non-HD brains (discovery cohort: OR 8.68, 95% CI 3.48–21.63, P=4.8 × 10-5; validation cohort: OR 6.50, 95% CI 1.83–23.17, P=0.0050). Periventricular nodular heterotopias (PNH) were the most frequent malformations and contained HTT and p62 aggregates analogous to the cortex, whereas cortical malformations with immature neuronal populations did not harbor such inclusions. HD individuals with malformations had heterozygous HTT CAG expansions between 40 and 52 repeats, were more frequently women, and all were asymmetric and focal, aside from one midline hypothalamic hamartoma. Using two independent brain bank cohorts, this large neuropathologic series demonstrates an increased occurrence of developmental malformations in HD brains. Since pathogenic HTT gene expansion is associated with genomic instability, one possible explanation is that neuronal precursors are more susceptible to somatic mutation of genes involved in cortical migration. Our findings further support emerging evidence that pathogenic trinucleotide repeat expansions of the HTT gene may impact neurodevelopment.

The complete absence of one of the uterine horns, named segmental uterine aplasia or unicorn uterus, occurs due to deficiency in the development of segments of the paramesonephric or Mullerian ducts. It is a congenital or hereditary anomaly of the female reproductive tract caused by recessive genes, which occurrence is unusual. In cows, this malformation was initially called “white heifer disease”, comprising an alteration in the Mullerian ducts in association with the white skin gene that causes aplasia of the uterus, cervix and vagina. Two pieces of sheep reproductive system from a slaughterhouse under federal inspection in the state of Bahia, Brazil, were received for pathological diagnosis. The collection, dissection and macroscopic analysis were carried out. In the macroscopic evaluation, uterine segmental aplasia was identified in both cases, with complete absence of the left uterine horns. Both had agenesis of the uterine tubes associated with the absence of internal bifurcation of the uterine horns. Animals that have a unicorn uterus often have reduced fertility which consequently leads to losses to sheep farming.

Context: Choledochal cyst is a rare malformation that mainly affects girls. Aims: The aim of this work is to report the diagnostic, therapeutic and evolutionary aspects of bile duct cyst in children in Dakar. Subjects and Methods: we conducted a prospective monocentre descriptive study from 1 July, 2016, to 30 June, 2019, in the Pediatric Surgery Department of Albert Royer Children's Hospital in Dakar. The studied parameters featured clinical, biological, radiological, therapeutic and evolutionary data. Overall, ten patients, including eight girls and two boys, were selected. Results: Two patients presented the classic triple-syndrome complex featuring an abdominal pain, an abdominal mass and jaundice. Most of the patients presented a symptomatology associating abdominal pain and vomiting. Biological cholestasis syndrome was present in six cases and biological cytolysis syndrome in five cases. The abdominal ultrasound-computed tomography (CT) scan confirmed the diagnosis and helped to set the Todani classification with a predominance of Types 1 and 4. Surgical treatment by laparotomy consisted of total excision of the cyst followed by a Y-en-Roux hepatico-jejunal anastomosis in nine cases, whereas we performed a drainage of the cyst in one case. Two patients presented a morbidity of anastomotic suture release and evisceration and had a good outcome after surgical repair. There was no mortality. Conclusions: The diagnosis of choledochal cyst dilatation (CCD) can be suspected in the postnatal period on the basis of a gastro-intestinal symptomatology with or without associated to jaundice. The combination ultrasound-abdominal CT-scan helps set the diagnosis. The laparatomic approach always has its place for the management of CCD, especially in our context.

Made available in DSpace on 2021-06-25T10:36:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-02-01 Background: Exercise is commonly recommended to control hyperglycemia, including during pregnancy. We conducted this study to understand the potential benefits and risks of exercise during pregnancy of women with diabetes. Specifically, we evaluated the effects of swimming on a diabetic rat during pregnancy and assayed maternal-fetal parameters. Methods: Diabetes was induced in the female newborn from Wistar rats by the streptozotocin administration on first postnatal day. At 110 days of life, after confirm mild symptoms of diabetes, the rats were mated and randomly distributed into four experimental groups (minimum of 13 animals/group): Control (C)—nondiabetic animals without swimming; Control and Exercise (CEx)—nondiabetic animals submitted to swimming; Mild Diabetic (MD)—diabetic animals without swimming; Mild Diabetic and Exercise (MDEx)—diabetic animals submitted to swimming. The swimming program was performed from day 7 to 21 of pregnancy. Maternal parameters were evaluated during the pregnancy period. On day 21 of pregnancy, the rats were sacrificed and maternal and fetal parameters analyzed. Results: There are no alterations in body weight, food consumption, water intake, and reproductive outcomes among the groups. The swimming program did not normalize maternal glycemia and other biochemical biomarkers. The diabetes and exercise combination increased organ weight. The fetuses born to these exercising diabetic rats had reduced fetal weight and increased skeletal anomalies (mainly incomplete ossification of sternebra). Conclusion: The intense swimming exercise imposed on female rats during pregnancy impaired maternal metabolic repercussions, contributing to intrauterine growth restriction and fetal skeletal anomalies.

Case Description A 10‐month‐old neutered male mixed breed dog was presented for assessment of poorly controlled seizures. Clinical Findings Magnetic resonance imaging of the brain disclosed complete absence of the lateral and third ventricles and mesencephalic aqueduct. Postmortem computed tomographic (CT) imaging and positive contrast cisterno‐ventriculography confirmed the lack of a contiguous ventricular system. However, histopathology identified the presence of vestigial lateral and third ventricles with hypoplastic choroid plexus, atresia of the third ventricle, and fused thalami, consistent with a diagnosis of lobar holoprosencephaly (HPE). Clinical Relevance To our knowledge, this report is the first case of radiographically confirmed aventriculi associated with HPE, a rare congenital malformation previously reported in people, to be described in veterinary medicine.

Determining if reproductive failures in ewes at the semiarid region in the state of Bahia are related to the consumption of the species Cenostigma pyramidale (Tul.) Gagnon & G.P. Lewis, and this study was developed using pregnant ewes divided into six groups: G1, G2, G3, G4 with six animals each, G5 and G6 with ten animals. Each group received fence leaves in the proportion of 1%, 2%, 0.5%, and 0.25% of live weight (LW) respectively; G5 and G6, with ten animals each, receiving 0.25% and 0.5% of the LW, respectively, and the Control Group, comprising 16 ewes, were grass feeding (Cynodon dactylon). Ewes from G1 to G4 were the same, except for two, and started ingestion of the plant four days after ending of natural mating on the 80th day of gestation, while those regarding from G5 to G6 groups started ingestion on the 26th day of gestation ending on the 98 day. The ultrasonographic test was performed weekly. In G1 ewes (1%), there was an embryonic loss on the 32nd and 39th days of gestation and abortion on the 46th day. In G2 (2%), the embryo loss was earlier (on the 26th day of gestation), and abortion on the 46th day of gestation. In G3 group (0.5%), there was an embryonic loss around the 40th day of gestation. In G4 group (0.25%), it was observed the occurrence of one death lamb with bone malformations. In G6 (0.5%), abortion occurred later (108 days), followed by retained placenta. This was also verified in G5 group (0.25%). The presence of fetal malformation was found in death lambs born in G4 group, born alive from G5 and G6 groups, and one aborted from G6. In G5 and G6 groups, there were also genetic alterations on surviving lambs. In addition to these results, recurrent estrus was observed without gestation in G1, G2, G3, and G4 ewes. From the Control Group, 13 normal lambs were born without genetic alterations; furthermore, concerning a quadruple birth, three lambs were born dead. The results infer that species of C. pyramidale in low doses causes reproductive losses in pregnant ewes, therefore it is not recommended for sheep diet over the first 60 days of gestation. RESUMO: Para determinar se falhas reprodutivas em ovelhas na região semiárida da Bahia estão relacionadas ao consumo de Cenostigma pyramidale (Tul.) Gagnon & G.P. Lewis, foi realizado um estudo utilizando-se ovelhas prenhes divididas em seis grupos e dois Grupos Controle. Os grupos G1, G2, G3 e G4 com seis animais cada. Cada grupo recebeu folhas fenadas na proporção de 1%, 2%, 0,5% e 0,25% do peso vivo (PV) respectivamente; G5 e G6, com 10 animais cada, que receberam 0,25% e 0,5% do PV respectivamente. Os Grupos Controle foram alimentados com ração e capim (Cynodon dactylon). Ovelhas dos grupos 1 a 4 iniciaram ingestão da planta quatro dias após monta natural com término aos 80 dias de gestação, enquanto as dos grupos 5 a 6 iniciaram ingestão no 26º dia de gestação com término aos 98 dias. Avaliação ultrassonográfica foi realizada semanalmente. Nos animais do G1 (1%), verificou-se perda embrionária aos 32 e 39 dias de gestação, e aborto aos 46 dias. Nos do G2 (2%) a perda embrionária foi mais precoce (26 dias), e aborto aos 46 dias. No G3 (0,5%), houve perda embrionária em torno dos 40 dias. No G4 (0,25%), verificou-se ocorrência de natimorto com malformações aos 150 dias de gestação. No G6 (0,5%) o aborto ocorreu mais tardiamente (108 dias), seguido de retenção de placenta. Essa ocorrência também foi verificada no G5 (0,25%). A presença de malformação fetal foi encontrada em fetos natimorto do G4, nascidos vivos do G5 e G6, e um abortado do G6. No G5 e G6 também foram observadas alterações de aprumos em cordeiros sobreviventes. Do Grupo Controle nasceram 13 borregos normais, porém uma ovelha apresentou gestação quádrupla com três natimortos. Os resultados inferem que C. pyramidale fenada em baixas doses causa perdas reprodutivas em ovelhas gestantes, não sendo por isso recomendada para a dieta de ovelhas durante os primeiros 60 dias de gestação.

Periventricular nodular heterotopia is a common neuronal malformation in humans, often leading to epilepsy and other neurologic diseases. A 2‐month‐old female Chihuahua weighing 750 g was examined because of a history of epileptic seizures and abnormalities in gait and behavior. Results of the clinical examination were consistent with a multifocal neurologic disease with localization in the forebrain and spinovestibular system. The magnetic resonance imaging showed multiple bilateral periventricular nodules isointense to gray matter and ventriculomegaly. Histopathological and immunohistological examination of the brain revealed that periventricular nodules consisted of neurons, fewer astrocytes, and some oligodendroglia consistent with periventricular nodular heterotopias.

Rhombencephalosynapsis is a rare defect in the development of the cerebellum, characterized by partial or total agenesis of the vermis, with fusion of the cerebellar hemispheres in the midline. It is usually related to Gómez-López-Hernández Syndrome (cerebellar-trigeminal dermal dysplasia) and VACTERL association association (vertebral defects, vascular anomalies, anal atresia, cardiac anomalies, tracheoesophageal fistula with esophageal atresia, renal dysplasia and limb anomalies). A 5-year-old female patient with spastic cerebral palsy and hydrocephalus presented here, neuroimages documented the next features: absence of cerebellar vermis, periventricular leukomalacia, cerebellar tonsils descent and rhombencephalosynapsis. Other important imaging findings and associations in these cases are discussed.

The present study provides description of the osteology of Skipper Frog Euphlyctis cyanophlyctis. Seven adult specimens of E. cyanophlyctis from northern Western Ghats of India were cleared and double stained for studying osteological characteristics. The baseline description of osteological characters of cranial and post-cranial elements (paired nasals, tubular sphenethmoid, well-developed vomerine teeth, arciferal pectoral girdle, fan-shaped omosternum, cartilaginous W-shaped xiphisternum, hind limb with longest cylindrical humerus, V-shaped pectoral girdle and phalangeal appendages) provided in present study will help in further taxonomic investigations of the genus Euphlyctis. Further, the baseline information on osteology of Skipper frog will serve as a reference material for investigations related to malformations, either in this or related species. We also provide first observation on sacro-pelvic malformation in one of the studied specimens.

A agenesia da veia cava caudal é uma malformação que ocorre ainda no período da embriogênese, tendo como característica a ausência parcial ou total do órgão. Por se tratar de uma anormalidade às vezes assintomática, são achados raros encontrados em exames de imagem, podendo ser desde uma simples ultrassonografia, a uma tomografia computadorizada, sendo os mesmos os principais métodos para a detecção e fechamento do diagnóstico. Este trabalho tem como objetivo relatar um caso de um cão da raça Scott Terrier, de 8 anos e 4 meses, atendido em um hospital veterinário na cidade de Salvador-BA, que após a realização de ultrassom e tomografia, confirmou-se a agenesia da veia cava caudal.

Mango production faces several challenges, such as nutrient deficiency, physiological stress, and alternate bearing, which eventually affect tree productivity. This study was carried out during the 2017 and 2018 seasons to evaluate the effect of single and combined applications of humic acid (as potassium humate; 0.15%, 0.30%, 0.45%) and boron (as boric acid; 300, 600 mg·L−1) on ‘Zebda’ mango trees grown at Dir AlMalak region, Sharkeya Governorate, Egypt. Foliar spray was applied twice before flowering (first week of January and first week of February), and a third spray was applied by the beginning of flowering (first week of March) in both seasons. Humic acid and boron effectively enhanced tree growth, flowering, yield, and fruit quality. Humic acid was more effective than boron in this respect. Combined application of both materials surpassed the single application of each material on overall tree physiology and annual productivity. The observed results may be a consequence of the increase in tree photosynthetic pigments, nutrients, organic solutes, and phytohormones such as auxins, gibberellins, and cytokinins. The reduction in abscisic acid content may be related to the role of humic acid and boron protecting the plant against destructive oxidative reactions; improving the ability of the trees to withstand environmental stresses; thereby reduce floral malformation percentage, minimize the incidence of alternate bearing, and improve annual tree productivity and fruit quality. The most pronounced effect in this regard was noted with the application of 0.30% humic acid + 600 mg·L−1 boric acid.

Background.19.6 % of all fatal cases among Russian children who died in the first year of life are registered out-of hospital, and they are usually sudden. Out-of-hospital sudden unexpected infant death (OSUID) could be confused with sudden infant death syndrome (SIDS) followed by the wide variation in the diagnostic indicators of the syndrome.The aim of the studyis to reveal the pathological changes in the tissues and organs of 420 cases of OSUID (group 1) compared with 350 cases of death in the hospital (group 2), to estimate the conformity of the final diagnoses and to identify cases of OSUID, which were SIDS.Methods.From 2009 to 2016 pathoanatomical and virological study of the organs of 420 cases of OSUID (group 1) and 350 babies who died in a hospital were carried out.Results.It was established that the age of infants of the 1st group at the time of death in 71 % of cases corresponded to the age of SIDS. In terms of gestational age and body weight at birth babies of the 1st group turned out to be much more prosperous. Signs of rapid onset of death in this group: plethora of internal organs (83.3 %) and petechial hemorrhages (75.5 %) were present significantly more often than in the 2nd. In the 1st group, predominantly light acute respiratory viral infections (ARVI) with minimal pathologic signs and pneumonia were diagnosed, but pneumonia in 33.3 % not detected at autopsy. Purulent tracheobronchitis (0 and 21.4 %), bacterial pneumonia (6.3 and 26.3 %), a large area of lung damage (3.8 and 56.1 %) were detected much less frequently in the 1st group. In 38 % of the 1st group, pneumonia was the only cause of death, and in no case in the 2nd. Pathology of the cardiovascular system (55.2 and 87.7 %), central nervous system (58.6 and 90.9 %);urogenital system (34.8 and 62.9), inflammation of the membranes and brain tissue (21.9 and 70.0 %), signs of past or current intrauterine viral infection (29.5 and 64.0 %) in the 1st group was diagnosed much less frequently than in the 2nd, but congenital syphilis, HIV infection and hepatitis C — 3 times more often (12.9 and 3.7 %). The more frequent pathology of the adrenal glands in the 1st group (66.7 and 34 %) could cause inadequate responses to minimal exposure to external factors, including mild acute respiratory viral infections. The diagnosis of SIDS was made in 3 cases and in 3 more it was questionable. However, the presence of multisystemic pathology excludes the diagnosis of SIDS. The diagnosis of SIDS could be established in 30 cases in cases of slight ARVI without intoxication, shock liver or disseminated intravascular coagulation syndrome.Conclusion.The most cases of sudden death occurred in not obvious life-threatening conditions in socially disadvantaged families in the absence of adequate observation, diagnosis and treatment.

Background Lymphatic malformations are rare benign cystic tumors that result from localized disordered embryologic development of the lymphatic system and can develop anywhere in the body, predominantly in the head and neck. These lesions are classified according to the diameter of the largest cystic cavity within the lesion into microcystic and macrocystic types. Historically, surgical excision has been considered the mainstay of treatment and still remains the first therapeutic option of choice for many surgeons particularly for giant macrocystic lesions. Several alternative therapeutic modalities emerged including intralesional sclerotherapy and laser therapy with encouraging results. The study is designed to assess the effectiveness and safety of surgical excision as an initial therapeutic option in the management of these malformations. Results Asymptomatic mass with parental cosmetic and functional concerns was the mode of presentation in six (66.7%) patients. Seven (77.8%) patients were presented before the age of 2 years. Six (66.7%) of the patients had their lesions in the neck. Complete surgical excision was achieved in eight (88.9%) patients without any evident significant injury to vital neurovascular structures. None of the patients had any difficulties with breathing, swallowing, or phonation and cosmetic results were satisfactory in the majority (88.9%) of them. Conclusion Radical surgical excision of giant macrocystic lymphatic malformations in children is possible in experienced hands. It is an effective and safe initial therapeutic option and gives satisfactory esthetic and functional results.

Les jumeaux conjoints sont une malformation rare des grossesses gémellaires monozygotes et mono-amniotiques. Le pronostic fœtal de cette malformation reste très sombre, nécessitant un recours à une interruption de la grossesse si le diagnostic est posé précocement. Nous rapportons le cas de « jumeaux conjoints thoracopages » de H3 de vie, nés à terme à 40 SA + 3 jours, par voie basse. Ils sont nés de parents non consanguins, sans antécédent pathologique notable. La mère était jeune, primipare. La grossesse était suivie avec 5 consultations prénatales et 3 échographies obstétricales réalisées par un médecin inexpérimenté. Le diagnostic de jumeaux conjoints thoracopages a été évoqué à l´examen clinique et le bilan lésionnel établi à la tomodensitométrie (TDM). Cet examen a permis d´observer des anomalies cardiovasculaires incompatibles avec la vie. Aucune intervention n´a été faite, car les jumeaux décédaient à H23 de vie dans un tableau de détresse respiratoire aiguë. Les jumeaux conjoints constituent une anomalie congénitale rare. Un diagnostic échographique précoce permettrait de préciser les structures anatomiques communes, de rechercher une anomalie congénitale associée, d'organiser l'accouchement dans une structure adaptée et de programmer une prise en charge néonatale multidisciplinaire.

Etanercept is a tumor necrosis factor alpha (TNF-α) inhibitor chronically used to treat autoimmune diseases. However, the use of etanercept during pregnancy still needs to be further investigated. The aim of this study is to evaluate the etanercept treatment during pregnancy, analyzing maternal reproductive performance, fetal outcomes, and placental repercussions. Wistar rats (200–250 g) were mated and randomly distributed into two experimental groups: control and etanercept (n = 10 animals/group). Treatments with etanercept (0.8 mg/kg, s.c.), or saline (control group) were carried out on days 0, 6, 12, and 18 of gestation. On the morning of the 21st day of pregnancy, rats were euthanized in a CO2 chamber and submitted to laparotomy to remove the fetuses, placentas, ovaries, and maternal organs. There were no differences between groups in the following parameters: water and food consumption; placental efficiency; reproductive parameters, including number of corpora lutea and implants, reabsorption, and pre- and post-implantation losses. However, etanercept treatment increased liver weight, reduced fetal and placental weight, decreased the placental junction zone, reduced the percentage of normal fetuses, and increased visceral or skeletal fetal abnormalities. Therefore, etanercept resulted in damages more related to fetus and placenta. However, more studies with different doses are required to better predict possible injuries elicited using etanercept during pregnancy.

Dissertação de Mestrado Integrado em Medicina Veterinária, na área científica de Clínica O sinus dermoide é uma malformação congénita, que surge devido a uma falha no encerramento do tubo neural, resultando numa separação incompleta dos elementos ectodérmicos dos dérmicos durante a embriogénese. Assim, existem seis tipos descritos de sinus dermoide, sendo o tipo VI o mais grave. Com base na localização anatómica, os tipos de sinus dermoide também podem ser classificados em: a (se se situam na linha média dorsal), b (os que se situam na região da cabeça, exceto no nariz) e c (os da região do nariz). A raça Leão da Rodésia tem predisposição genética para esta malformação, contudo pode surgir em outras raças. É raramente documentada em gatos, ainda que, na amostragem, o gato birmanês esteja sobre representado. Espinha bífida oculta, sinónimo de disrafia espinal fechada, é uma malformação congénita em que o tecido nervoso não se encontra protegido pela coluna vertebral, mas não está em contacto com o meio ambiente, uma vez que está coberto pela pele. É, muitas vezes, um achado imagiológico acidental que não inflige sinais clínicos ao animal. O caso clínico descrito nesta dissertação, é uma raridade. Trata-se de uma paciente, Leão da Rodésia, diagnosticada com sinus dermoide tipo VI, um trato fistuloso que se prolonga por uma banda fibrosa até à dura-máter, que também tinha espinha bífida. O sinus localizava-se na região sagrada, comunicando com a medula espinal ao nível da segunda vértebra sagrada. A paciente apresentava dor e inflamação na região, contudo não apresentava sinais neurológicos. O animal foi submetido a exames de imagiologia avançados, como Tomografia Computorizada e Ressonância Magnética para delinear o planeamento cirúrgico de excisão do sinus. As margens de excisão cirúrgica do sinus foram limpas, minimizando a probabilidade de recidiva da malformação. Para além da remoção do trato sinuoso, foi realizada uma laminectomia dorsal na segunda vértebra sagrada. A paciente, 9 meses após a cirurgia, encontra-se bem, tendo recuperado toda a sua vivacidade e qualidade de vida, sem sinais de recidiva ABSTRACT - DERMOID SINUS TYPE VI ASSOCIATED WITH SPINA BIFIDA IN A RHODESIAN RIDGEBACK - The dermoid sinus is a congenital malformation, which occurs due to a failure of neural tube closure. It results in an incomplete separation of the ectodermal from the dermal elements during embryogenesis. Thus, there are six described types of dermoid sinus, with type VI being the most severe. Based on the anatomical location the types of sinus dermoid can also be classified into: a (if situated in the dorsal midline), b (those in the head region, except for the nose) and c (those in the nose region). The Rhodesian Ridgeback breed, has a genetic predisposition for this malformation, but it may occur in other breeds. It is rarely documented in cats, however the Burmese cat is over represented. Spina bifida occulta, synonymous with closed spinal dysraphia, is a congenital malformation in which the nerve tissue is not protected by the spinal column, but is not in contact with the environment, since it is covered by the skin. It is often an accidental imaging finding that does not inflict clinical signs to the animal. The clinical case described in this dissertation is a rarity. It is a patient, Rhodesian Ridgeback, diagnosed with type VI dermoid sinus, a fistulous tract extending through a fibrous band to the dura mater, which also had spina bifida. The sinus was located in the sacral region, communicating with the spinal cord at the level of the second sacral vertebra. The patient was in pain and presented inflammation in the region, however no neurological signs were present. The animal underwent advanced imaging examinations such as Computed Tomography and Magnetic Resonance Imaging to delineate the surgical planning for sinus excision. The margins of surgical excision of the sinus were clean, minimising the probability of recurrence of the malformation. In addition to removal of the sinus tract, a dorsal laminectomy was performed on the second sacral vertebra. The patient, 9 months after surgery, is doing well, having recovered all her liveliness and quality of life, with no signs of recurrence. N/A

Purpose A short fetal femur in prenatal diagnosis might be an indicator for intrauterine growth retardation (IUGR), a genetically determined small child (SGA) with or without associated fetal malformations and/or an adverse fetal outcome. Methods 1373 singleton pregnancies with a femoral length < 5th percentile detected between 1999 and 2015 during second-trimester screening in a tertiary prenatal diagnostic center were subjected to a descriptive retrospective analysis with regard to fetal characteristics as well as pregnancy outcome. Results 685 (49.9%) fetuses presented an isolated short femur, while 688 (50.1%) showed additional abnormalities. 293 (42.6%) of those were SGA babies without any malformation, while 395 (57.4%) had one or more severe anomaly of the following organ systems: 157 (11.5%) cardiovascular, 101 (7.4%) musculoskeletal, 82 (6.0%) urogenital, 72 (5.2%) cerebrocephalic, 50 (3.6%) gastrointestinal, and 5 (0.4%) thoracic. 75 (5.5%) of the fetuses showed chromosomal aberrations of which Trisomy 13, 18 and 21 were found in 2, 13 and 27 of the cases, respectively. Fetuses with associated malformations had a significantly lower live birth rate than those without (64.2% vs. 98.1%, p < 0.001); in addition, a higher rate of preterm births 36.6% vs. 11.3%, p < 0.001) and SGA babies (51.4% vs. 30.4%, p < 0.001) were observed in the first collective. Conclusion Diagnosis of a short fetal femur should lead to an extended organ screening; in the case of associated abnormalities, additional genetic testing has to be offered, as well as intensified pregnancy monitoring in pregnancies at risk for IUGR and/or preterm birth., publishedVersion

The human brain is characterized by the large size and intricate folding of its cerebral cortex, which are fundamental for our higher cognitive function and frequently altered in pathological dysfunction. Cortex folding is not unique to humans, nor even to primates, but is common across mammals. Cortical growth and folding are the result of complex developmental processes that involve neural stem and progenitor cells and their cellular lineages, the migration and differentiation of neurons, and the genetic programs that regulate and fine-tune these processes. All these factors combined generate mechanical stress and strain on the developing neural tissue, which ultimately drives orderly cortical deformation and folding. In this review we examine and summarize the current knowledge on the molecular, cellular, histogenic, and mechanical mechanisms that are involved in and influence folding of the cerebral cortex, and how they emerged and changed during mammalian evolution. We discuss the main types of pathological malformations of human cortex folding, their specific developmental origin, and how investigating their genetic causes has illuminated our understanding of key events involved. We close our review by presenting the animal and in vitro models of cortex folding that are currently used to study these devastating developmental brain disorders in children, and what are the main challenges that remain ahead of us to fully understand brain folding.

Dysmorphic uterus is a condition that can affect fertility differently depending on the type of malformation. The most common uterine malformation is the septum but other uterine malformations can affect fertility, as t-shaped uterus

Congenital diaphragmatic hernia (CDH) is a developmental malformation characterized by a defect in the diaphragm that allows abdominal viscera to move into the chest cavity. A routine ultrasound screening performed during pregnancy detects over half of all cases. This paper describes two women who were prenatally diagnosed to have a fetus with isolated posterolateral CDH. Both mothers underwent medical abortion. In the first case, a postmortem examination of the fetus revealed a large right-sided CDH, in which a part of the liver and small intestine were propagated into the chest. In the second one, a huge left-sided CDH was identified, in which the entire stomach, a large proportion of the small intestine and part of the left lobe of the liver were pushed up into the thoracic cavity. CDH is a diagnostically challenging birth defect with a marked variation in severity and corresponding survival. In utero-diagnosed cases usually represent more severe and prognostically unfavorable conditions than those that were postnatally diagnosed. Early prenatal detection of CDH may help improve the clinical outcome as the mother can be referred to a specialist center before the onset of labor for optimal perinatal management. A legal medical abortion should be the last option after all the others have been exhausted.

Aim: The aim of this study was to review the craniofacial anomaly results of children diagnosed with ectodermal dysplasia (ED) and to identify the oral requirements of ED cases. Methodology: The data of this study were obtained by taking clinical examinations and radiographs on forty-four (44) children (22 females and 22 males), 0-16 years aged, who were admitted to the Dicle University, Faculty of Dentistry due to dental problems and were diagnosed with ED. The number of affected siblings was ascertained, and systemic findings were evaluated. Malformations in the hair, nails, nose, skin, lips, and teeth were clinically examined. Results: The most common clinical findings were sparse hair, dry skin, sweating problems, respiratory difficulty, saddle nose, a history of fever, hearing loss, and deformation in the nails. In the intraoral and radiological examinations, findings were evaluated of conical teeth, protuberant lips, prosthetic rehabilitation, impacted teeth, and abnormal root resorption. The rates of ED in the siblings of the ED cases were determined as 39.2% in the siblings of male cases and 37.9% in the siblings of female cases. Conclusion: The frequency rates of the anomalies seen in ED obtained in this study can be considered important as a guide for further studies of individuals with ED. When multiple missing teeth and conical teeth are encountered, the dental practitioner should investigate whether or not there are other symptoms of ED, and it must not be forgotten that the dentist may be the first step in the diagnosis of this genetic irregularity.

Background The cysts of the male pelvic floor represent a rare clinical entity. Their origin is linked to an altered development of paramesonephric and mesonephric ducts during embryogenesis. Case presentation We report our experience regarding two patients presenting cysts of the ejaculatory system treated with open and mini-invasive surgery. The patients referred to our clinic with nonspecific symptoms and the diagnosis was obtained by radiological investigations. The patient treated with an open approach developed a pelvic purulent collection and a fistula of the prostatic urethra, managed with surgical drainage and prolonged bladder catheterization. On the other hand, the patient treated with laparoscopic approach did not develop any complications. No sexual or ejaculatory disorders were reported. Conclusions Patients with congenital cysts of the pelvic floor must be adequately informed about the risks and benefits of surgery and a careful counseling is mandatory before surgery. Treatment is recommended for symptomatic patients and an endoscopic approach is associated with a high rate of recurrence. A laparoscopic approach, when possible, is desirable.

Caroli syndrome is characterized by a combination of intrahepatic biliary ductal ectasia and congenital ductal fibrosis due to the failure of involution of ductal plates and large intrahepatic ducts. This study aims to report Caroli syndrome in a dog, with emphasis on clinical characteristics, complementary examinations, and diagnostic approach. A 1-year-old mixed-breed intact male dog was presented with a 7-day history of acute vomiting and anorexia. Clinical evaluation revealed severe jaundice, abdominal pain, dehydration, lethargy, and abdominal distension. Ultrasonography revealed hepatic cysts filled with fluid. Exploratory laparotomy was performed to clarify the imaging findings; however, the dog died shortly after surgery. Postmortem examination revealed that the liver was reduced in size and had multiple interconnected and distended saccular dilations. The bile ducts were markedly dilated and replaced a large part of the liver parenchyma. Multiple small cysts were also observed in the kidneys. Microscopically, the hepatic lesions were characterized by extensive bridging fibrosis associated with proliferating and ectatic bile ducts contiguous with the biliary tree. Marked fibrosis and small cysts were observed in the kidneys. Therefore, a final diagnosis of Caroli syndrome was made. While uncommon, this syndrome should be considered as a differential diagnosis for young dogs with biliary cysts and hepatic fibrosis. RESUMO: A síndrome de Caroli é caracterizada pela combinação de ectasia biliar intra-hepática e fibrose ductal congênita, que se devem a falha na involução das placas ductais dos grandes ductos intra-hepáticos. Esse trabalho tem a intenção de reportar um caso de síndrome de Caroli em um canino, com ênfase em suas características clínicas, exames complementares, e abordagem diagnóstica. Um canídeo de um ano de idade, sem raça definida, apresentou um histórico clínico de sete dias de vômito agudo e anorexia. A avaliação clínica revelou severa icterícia, dor abdominal, desidratação, letargia e distensão abdominal. A ultrassonografia foi sugestiva de cistos hepáticos preenchidos por fluido. Uma laparotomia exploratória foi realizada para esclarecer os achados de imagem, porém, o cão morreu logo após a cirurgia. O cão foi submetido a exame de necropsia, onde se observou fígado diminuído em tamanho e com múltiplas dilatações saculares distendidas e interconectadas entre si. Os ductos biliares estavam acentuadamente dilatados e substituíam grande parte do parênquima hepático. Nos rins, múltiplos pequenos cistos eram observados. Microscopicamente as lesões hepáticas eram caracterizadas por extensa fibrose em ponte, associada a ductos biliares ectáticos e proliferados, que eram contíguos a árvore biliar. Nos rins, marcada fibrose e pequenas formações císticas foram observadas. Baseado na associação dos achados clínicos e patológicos, o diagnóstico de síndrome de Caroli foi feito. Mesmo que incomum, essa síndrome deve ser considerada como um diagnóstico diferencial para cães jovens com ductos biliares císticos e fibrose hepática.
