Introduction: Odontomas are one of the most common odontogenic tumours and are classified as benign odontogenic tumours. According to radiographic, microscopic and clinical features there are two main types of odontomas: compound and complex. Aim: To analyse the prevalence of benign odontogenic tumours compatible with odontomas in digital panoramic radiographs in a Brazilian population. Materials and Methods: This retrospective study was conducted from January 2015 to December 2015 and analysed 2,167 digital panoramic radiographs from the database of a Specialised Dental Radiological Clinic in Belo Horizonte, Brazil. Results: Seven images presented lesions compatible with odontomas, resulting in a prevalence rate of 0.32%. Three images (42.9%) were compatible with compound odontomas and 4 (57.1%) with complex odontomas. Regarding gender, the majority of odontomas were found in female patients (71.4%). The age of the patients diagnosed with odontomas ranged from 7 to 37 years and the main clinical manifestation observed was their association with non-erupted teeth. Regarding the location of the lesions, compound odontomas were mainly observed in the incisor region (66.6%), whereas complex odontomas were found in the posterior region of the molars (50.0%). Conclusion: Data presented in this study reinforce the importance of panoramic digital radiographic images during dental practice for incidental diagnoses of odontogenic tumours, such as odontomas, since these lesions are in most cases, asymptomatic.

Low anterior resection syndrome has a negative impact on quality of life. Intestinal irrigation is a method of lavage consisting of a scheduled evacuation.This study aims to evaluate functional and quality-of-life outcomes in patients with low anterior resection syndrome after transanal irrigation using a colostomy irrigation system.This was a prospective case series.This study presents a single-center experience at a tertiary oncological center in an upper-middle-income country.Patients classified as having minor or major low anterior resection syndrome 12 months after their operation were selected.Transanal irrigation was performed using an ostomy irrigation kit. Questionnaires assessing patients' bowel function (low anterior resection syndrome and Wexner score) and quality of life (Short Form-36 questionnaire) were applied before and after treatment.The primary outcomes were low anterior resection syndrome score and quality-of-life improvement after a 12-month treatment.Of the 22 patients included, 20 had major and 2 had minor low anterior resection syndrome, with a median score of 39, especially high rates of incontinence for liquid stool (21; 95.5%), clustering (21; 95.5%), and urgency (17; 77.3%). All patients successfully completed the 3-day training, and there were no complications during the treatment. After the 12-month period, the median score was 8, with 90% of the patients classified as having "no syndrome" and great improvement in all domains of this score. The most improved quality-of-life sections were patient vitality (p = 0.025) and physical (p = 0.002), social (p = 0.001), and emotional aspects (p = 0.001).The study was limited by its small sample size and the limited follow-up period.This study presents a safe implementation protocol of an ostomy irrigation device for transanal irrigation. It also adds to the literature that transanal irrigation is a safe, effective, and easily implemented procedure for patients with low anterior resection syndrome with a significant improvement in quality of life.

La irrigación intestinal es un método de lavado que consiste en evacuaciones programadas.OBJETIVOS:Evaluar los resultados de la funcionalidad e impacto en la calidad de vida de los pacientes con síndrome de resección anterior y baja posterior a la irrigación transanal utilizando un sistema de irrigación de colostomía.DISEÑO:Es estudio prospectivo de una serie de casos.ESCENARIO:En este estudio se muestra la experiencia de un centro oncológico de tercer nivel en un país en vías de desarrollo.PACIENTES:Aquellos clasificados como síndrome con afección en menor o mayor grado doce meses después de la cirugía.METODO:Se efectuó irrigación transanal utilizando un equipo de irrigación de estomas. Se aplicaron cuestionarios para valorar la función intestinal de los pacientes (síndrome de resección anterior baja y la escala de Wexner) y para calidad de vida (Cuestionario Corto-36) antes y después del tratamiento.EVALUACION DE LOS RESULTADOS PRINCIPALES:Los principales resultados se obtuvieron de la escala del síndrome de resección baja y la mejoría en la calidad vida doce meses después de tratamiento.RESULTADOS:De los veintidós pacientes incluidos, veinte presentaron manifestaciones mayores del síndrome de resección baja y dos, manifestaciones menores. Con una media de treinta y nueve, se encontraron, especialmente, altos índices de incontinencia a líquidos (21; 95'5%) hiperdefecación "clustering" (21; 95'5%) y urgencia (17; 77'3%). Todos los pacientes completaron en forma satisfactoria el entrenamiento de tres días sin presentarse complicaciones durante el tratamiento. Al término del mes doce la media fue de ocho, con el 90% de los pacientes clasificados como "sin síndrome" y se observó una mejoría substancial en todos los puntos de la evaluación. Las secciones de calidad de vida que mostraron una mejoría significativa fueron: la vitalidad del paciente (p = 0'025), física (p = 0'002), social (p = 0'001) y emocional (p = 0'001).LIMITACIONES:El tamaño de la muestra es pequeño y el tiempo de seguimiento corto.CONCLUSIONES:Este estudio muestra la implementación de un protocolo seguro para la irrigación de estomas mediante un dispositivo transanal. Además contribuye con el concepto en la literatura de que la seguridad de la irrigación transanal es seguro, efectivo y facilmente reproducible para pacientes con síndrome de resección anterior baja con una mejoría significativa en la calidad de vida.

O diagnostico de incontinencia anal (IA) se caracteriza pela saida nao intencional de fezes liquidas ou solidas e gases, em um periodo de, no minimo, um mes. Essa condicao esta diretamente associada com uma perda de qualidade de vida (QV), com impacto negativo no meio familiar, laboral e social do individuo. O tratamento conservador e a primeira opcao, com adocao de medidas clinicas com aconselhamento aos pacientes a respeito de dietas e praticas de reabilitacao da musculatura pelvica, associado a intervencoes farmacologicas. Outra terapeutica proposta e a irrigacao transanal, que permite um esvaziamento intestinal para a maioria dos pacientes em 24h a 48h, garantindo uma autonomia individual quanto a rotina intestinal destes pacientes. As buscas foram realizadas em duas bases de dados bibliograficos, Pubmed e LILACS. Foram selecionados quinze artigos publicados entre 2000 e 2019, escritos em ingles e em portugues. Optou-se pela busca de termos livres. O tratamento para IA e desafiador e necessita ser individualizado, tanto os tratamentos conservadores como os invasivos. Situacoes de isolamento social e quadros psiquiatricos depressivos vem sendo cada vez mais evidenciados em pessoas com IA, de forma a tornar fundamental a indicacao do tratamento efetivo. A condicao IA gera um estigma no paciente que recebe este diagnostico, com impacto negativo na QV e autoestima, que podem se desdobrar em outras comorbidades. O conhecimento das opcoes terapeuticas e a indicacao precisa e de fundamental importância para o bem-estar do paciente.

Purpose: This article aims to present a standardization of the technique of transanal therapeutic irrigation, which is an old technique that has passed through history and is now used as a medical procedure to assist in the treatment of defecation disorders. Methods: This protocol was developed in patients with myelomeningocele submitted to the standard transanal therapeutic irrigation technique, in accordance with the protocol established at the Clinic of defecation disorders at a public university hospital in Brazil. The presented standard technique highlights the following topics: preparation of the patient before the treatment; interdisciplinary approach; training of the patient or the family member responsible for the patient and the step-by-step technique itself. The research ethics committee at the university approved this study. Discussion: Transanal therapeutic irrigation is indicated in neurogenic bowel dysfunctions and functional disorders of defecation. Training the patient or a family member responsible for irrigation is performed on three consecutive days, all of them supervised by the nurse. This technique aims to re-establish control over defecation and bowel function, and consists in an infusion of warm tap water through the anus, which allows the patient to evacuate daily the stool and keep the colon empty for longer periods. This avoids fecal incontinence and increases the quality of life of patients with defecation disorders. Conclusion: Transanal therapeutic irrigation is an effective, well-tolerated and safe procedure, which is better compared to the standard clinical care. Resumo: Objetivo: Este artigo tem como objetivo apresentar uma padronização da técnica de irrigação transanal terapêutica, uma técnica antiga que passou pela história e tem sido utilizada como procedimento médico para auxiliar no tratamento de distúrbios de defecação. Métodos: Este protocolo foi desenvolvido em pacientes com mielomeningocele submetidos à técnica de irrigação terapêutica transanal padrão, de acordo com o protocolo estabelecido na Clínica de Distúrbios da Defecação de um hospital universitário público no Brasil. A técnica padrão apresentada destaca os seguintes tópicos: preparação do paciente antes do tratamento; Abordagem interdisciplinar; treinamento do paciente ou do membro da família responsável pelo paciente e a técnica passo a passo em si. O comitê de ética em pesquisa da universidade aprovou este estudo. Discussão: A irrigação transanal terapêutica está indicada nas disfunções intestinais neurogênicas e nos distúrbios funcionais da defecação. O treinamento do paciente ou de um familiar responsável pela irrigação é realizado em três dias consecutivos, todos supervisionados por uma enfermeira. Esta técnica visa restabelecer o controle sobre a evacuação e a função intestinal, e consiste em uma infusão de água da torneira quente através do ânus, que permite ao paciente evacuar diariamente as fezes e manter o cólon vazio por períodos mais longos. Isso evita a incontinência fecal e aumenta a qualidade de vida dos pacientes com distúrbios de defecação. Conclusão: A irrigação terapêutica transanal é um procedimento efetivo, bem tolerado e seguro, o qual é melhor quando comparado ao tratamento clínico padrão.

Ethnopharmacological relevance Morus nigra L. is a plant native to Asia, and well adapted to the Brazilian climate. It is popularly known as "amoreira preta”, and is part of the National List of Plants of Interest to the Brazilian Unified Health System. It is used in folk medicine mainly to soften the effects of menopause, as anti-inflammatory, antidiabetic and antihypertensive. However, information on safe doses and use is still precarious. Aim of the study To identify the chemical composition of the ethanolic extract of Morus nigra L. leaves (EEMN), as well as perform a toxicological study in male and female rats. Materials and methods The chemical composition of the extract was performed by HPLC/DAD. In the acute study, the dose administered was 2000 mg/kg, and signs of toxicity and mortality was observed. In the sub-acute study, the extract was administered at doses of 500, 750 and 1000 mg/kg for 28 days. Behavioral changes, object recognition test, renal and hepatic tissue assessments, biochemical and hematological parameters were determined. The extract was administered orally to male and female rats in both studies. Results Quercetin and caffeic acid showed as major compounds in the extract. In the acute treatment, the extract was classified as safe (category 5), according to the protocol. In the subacute study, there was a decrease in AST in males (750 and 1000 mg/kg) and females (1000 mg/kg), reduction of total cholesterol in females (750 and 1000 mg/kg), and increase in renal and hepatic change the LPO levels. Conclusion The present investigation showed that EEMN did not present significant toxic effects when administered orally. Moreover, presented a potentially protective action of organs and possesses hypocholesterolemic activity, thus, it is shown as a promising natural source to be used in pharmacology.

The ability to detect important clinical changes, or responsiveness, is a necessary property of a questionnaire for measure oral health-related quality of life, especially when one wishes to evaluate the effect of clinical therapies to improve the quality of life of patients. However, in Brazil, there are no studies that evaluated the responsiveness of measures destined for adolescents. Aim: The goal of this dissertation is to present a paper of the responsiveness of the Brazilian versions of Child Perceptions Questionnaire (CPQ11-14) and Child Oral Impacts on Daily Performances (Child-OIDP). Material and Methods: Data were collected from a convenience sample of 101 patients of 11-14-year-old attending at adolescent Dental Clinic, Federal University of Santa Maria, Brazil. Subjects answered the CPQ11-14 and the Child-OIDP in two moments: prior to dental treatment and one month later the conclusion of treatment. The responsiveness of CPQ11-14 and Child-OIDP was analyzed through: (I) the mean change observed in scores before and after treatment, (II) an investigation the effect size, (III) an assessment of the statistical significance of within-groups changes over time according to global transition judgement, and (IV) the receiver operating characteristic (ROC) curve, through the sensitivity and specificity of the questionnaires. Results: Positive changes occurred throughout the sample for CPQ11-14 and Child-OIDP. According to global transition judgment, 90.1% of participants reported an improvement following treatment, 7.9% reported no change and 2% reported deterioration. The effect size was 1.0 for the overall CPQ 11-14 and 0.5 for Child-OIDP. In ROC analyses, the area under the curve (AUC) was 0.53 for CPQ11-14 and 0.55 for Child-OIDP. Conclusion: The Brazilian versions of CPQ11-14 and Child-OIDP demonstrated limited responsiveness after dental treatment.%%%%A capacidade de avaliar mudancas clinicas significativas responsividade e uma propriedade fundamental na escolha de um questionario para mensurar qualidade de vida relacionada a saude bucal, principalmente quando se deseja avaliar o efeito de terapias clinicas na qualidade de vida dos pacientes.

Introduction: Acute appendicitis is the most common surgical disease of the abdomen in clinical practice, affecting mainly young adults. It has a wide variety of clinical presentations, due to the anatomical variation of the cecal appendix. Its presentation as acute scrotum and scrotal abscess is quite rare and atypical, occurring mainly in young male patients with patent processus vaginalis. Case presentation: An 18-years-old male patient attended the emergency unit complaining of diffuse abdominal pain, fever and hyporexia for four days followed by inflammatory signs in the scrotum. He was taken to the operation room after diagnosis of scrotal and abdominal sepsis. During scrotum exploration, pus was found inside the right hemiscrotum coming down from the groin and communicating with the abdominal cavity. The laparotomy found perforated appendicitis and peritonitis leading to the scrotal abscess. The abscess was drained, appendectomy was performed and the scrotal and abdominal cavity were washed with saline solution. Despite postoperative complications such as pneumonia and intra-abdominal abscess, the reported patient recovered and was discharged in the 44th postoperative day. Conclusion: Acute appendicitis can mimic acute scrotum and surgeons must have a high index of suspicion of this complication for diagnosing. This unusual clinical presentation may be challenging and can delay the diagnosis leading to perforated peritonitis. Resumo: Introdução: A apendicite aguda é a doença cirúrgica mais comum do abdome na prática clínica, afetando principalmente adultos jovens. Tem uma grande variedade de apresentações clínicas, devido à variação anatômica do apêndice cecal. Sua apresentação como escroto agudo e abscesso escrotal é bastante rara e atípica, ocorrendo principalmente em pacientes jovens do sexo masculino com túnica vaginalis patente. Apresentação do caso: um paciente do sexo masculino de 18 anos de idade compareceu à unidade de emergência queixando dor abdominal difusa, febre e hiporexia por quatro dias que se seguiram de sinais inflamatórios no escroto. Ele foi levado para centro cirúrgico após o diagnóstico de sepse de origem escrotal e abdominal. Durante a exploração da bolsa escrotal, secreção purulenta foi encontrada do lado direito oriunda do canal inguinal e comunicando-se com a cavidade abdominal. Durante a laparotomia observou-se sinais de apendicite aguda perfurada e peritonite levando ao abscesso escrotal. O abscesso foi drenado, a apendicectomia foi realizada e as cavidades escrotal e abdominal foram lavadas com solução salina. Apesar de complicações pós-operatórias como pneumonia e abscesso intra-abdominal, o paciente recuperou-se bem, recebendo alta hospitalar no 44° dia pós-operatório. Conclusão: A apendicite aguda pode simular o escroto agudo e os cirurgiões devem ter um alto grau de suspeição dessa complicação para o diagnóstico. Esta apresentação clínica incomum pode ser desafiadora e retardar o diagnóstico levando à peritonite por perfuração.

Justificativa: A hérnia diafragmática é uma complicação incomum nos procedimentos cirúrgicos torácicos e abdominais, mas importante pois submete o paciente à uma nova intervenção e põe a vida do mesmo em risco. Caso: Paciente masculino submetido a nefrectomia total após necrose por litíase renal. No pós-operatório apresentou sintomas dispépticos; o estudo de imagem revelou hérnia diafragmática esquerda com protusão total do estômago na região torácica. Discussão: A hérnia diafragmática é definida como a evisceração transdiafragmática de conteúdo abdominal no tórax, afetando mais frequentemente o estômago. Podem ser classificadas em congênitas e adquiridas, prevalecendo a Bochdalek como a principal herniação congênita. A hérnia diafragmática iatrogênica é uma complicação rara, existindo poucos relatos na literatura. O diagnóstico é estabelecido pelo exame de Tomografia Computadorizada que evidencia a protusão da víscera na cavidade torácica. O tratamento de escolha é cirúrgico.

Background: Fecal incontinence causes a big impact on patient's quality of life. Our study analyzed the main questionnaires about fecal incontinence available internationally, aiming to delineate vantages and limitations of these instruments and their application, to mention the cultural aspects involved in the process of development and validation, as well as to suggest a reflection about the complexity of this matter. Results: Four of the instruments (Pescatori score, FISI, MSKCC bowel function instrument, and LARS score) do not include quality of life, working only as diagnostic tools. Two others, ‘Jorge and Wexner Fecal Incontinence score’, and ‘St Marks’ Fecal incontinence grading system’ can diagnose and grade fecal incontinence, however they are very subtle in assessing quality of life. The ‘EORTC Colorectal Cancer-specific’, on the other hand, focuses exclusively on quality of life. Although the ‘FIQL’ questionnaire assesses quality of life related to fecal incontinence, it does not measure leakage. Lastly, the ‘RAFIS’ assesses both aspects but too superficially. Conclusion: None of the questionnaires analyzed were able to simultaneously assess both fecal incontinence and quality of life successfully. Furthermore, the concepts related to fecal incontinence have different meanings depending on the cultural and psychosocial context. These differences are even greater when individuals of developed countries like the ones where these questionnaires were developed are compared to the ones of developing countries, such as Brazil, which makes its very hard for these instruments to be used universally. Resumo: Contexto: A incontinência anal acarreta grande impacto na qualidade de vida (QV) dos pacientes. Nosso estudo analisou os principais questionários sobre o tema disponíveis na literatura internacional, visando delinear vantagens e limitações desses instrumentos e de sua correta aplicação, bem como citar os aspectos culturais envolvidos no processo de sua criação e validação, e sugerir uma reflexão sobre a complexidade do tema. Métodos: Nessa revisão assistemática, utilizamos três bases de dados eletrônicas (MEDLINE, LILACS, e DeCS) para encontrar os 9 questionários mais utilizados no mundo, e palavras-chave relacionadas. Resultados: Quatro dos instrumentos estudados (Pescatori score, FISI, MSKCC bowel function instrument, e o LARS score) não abordam QV, funcionando apenas para diagnóstico. Outros dois, o ‘Jorge and Wexner FI score’, e o ‘St Marks’ FI grading system’ diagnosticam e graduam bem a incontinência, porém apenas avaliam brevemente a QV. O ‘EORTC Colorectal Cancer-specific’, por sua vez, foca exclusivamente na QV. O questionário ‘FIQL’ apesar de conseguir avaliar a QV relacionada à função intestinal, não avalia vazamentos. Por fim, o ‘RAFIS’ avalia de forma muito simplificada esses aspectos. Conclusão: Nenhum dos questionários analisados se mostrou eficiente na avaliação simultânea da incontinência e da QV. Além disso, os conceitos que envolvem incontinência anal apresentam significados diferentes dependendo do contexto cultural e psicossocial. Essas diferenças são ainda maiores quando se comparam indivíduos dos países desenvolvidos onde esses questionários foram desenvolvidos, com os de países subdesenvolvidos como o Brasil, dificultando sua aplicação de forma universal.

RESUMO Objetivo: avaliar os fatores associados ao não fechamento de ileostomia protetora após ressecção anterior do reto com excisão total do mesorreto por câncer retal, a morbidade associada ao fechamento destas ileostomias e a taxa de estomia permanente em pacientes com adenocarcinoma retal. Métodos: estudo retrospectivo de 174 pacientes consecutivos com diagnóstico de tumores retais, dos quais 92 foram submetidos à ressecção anterior do reto com intenção curativa, anastomose coloanal ou colorretal e ileostomia de proteção. Foi realizada análise multivariada visando a determinar os fatores associados à permanência definitiva da estomia, assim como o estudo da morbidade nos que se submeteram à reconstrução do trânsito. Resultados: no período de seguimento de 84 meses, 54 dos 92 pacientes avaliados (58,7%) tiveram a ileostomia fechada e 38 (41,3%) permaneceram com a estomia. Entre os 62 pacientes que tiveram a ileostomia fechada, 11 (17,7%) apresentaram algum tipo de complicação pós-operatória: três com deiscência de anastomose ileal, cinco com obstrução intestinal, dois com infecção de ferida operatória e um com pneumonia. Oito destes pacientes necessitaram de um novo estoma. Conclusão: de acordo com a análise multivariada, os fatores associados à permanência da estomia foram fístula de anastomose, presença de metástases e fechamento da ileostomia durante quimioterapia.

The survival of the nematode parasite free-living stages depends mainly on environmental factors (i.e. rainfall, temperature and relative humidity). To complete its life cycle outside the host the parasite eliminated as eggs in the fecal material, develop to three larval stages before is ingested by the host. Although the presence of infective third stage larvae (L3) on pasture is of great importance for producers and researchers to determine the level of infectivity, the quantification of L3 on pasture is often neglected. Such condition can be determined by pasture larval count (PLC) from a target area. As anthelmintic resistance is widely overspread PLC technique supports population dynamic and epidemiological studies and can be used for measuring the success rate of livestock management strategies under different climatic conditions. The present review article brings together some of the field applications and difficulties to run and interpret this technique, encouraging its use as a diagnostic procedure.

Objectives: Anal sphincteroplasty with Deoti's flap is a recently published procedure for the treatment of fecal incontinence with severe perineal deformity. The aim of this study is to report six cases of patients, analyzing their results in fecal incontinence questionnaires and proposing a new scale to better assess our technique's main objective, the reconstruction of the perianal anatomy. Methods: Six patients were submitted to anal sphincteroplasty with Deoti's flap and follow-up was performed every six months. Functional results and Quality of Life were measured by Wexner Score and Fecal Incontinence Quality of Life Scale, respectively. Results: All operations were carried out without failure to perform Deoti's flap rotation. The sample presented medians of 18.5 and 3.5 on Wexner Score, before and after surgery, respectively. In the Fecal Incontinence Quality of Life Scale, the medians before and after surgery are, respectively, 1.75 and 3.35 (Scale 1), 1.54 and 2.60 (Scale 2), 2.35 and 3.28 (Scale 3), 1.49 and 3.33 (Scale 4). The p-values were 0.0173 for Wexner Score and 0.0260, 0.0411, 0.0368 and 0.0952 for Scales 1, 2, 3 and 4 of Fecal Incontinence Quality of Life Scale, respectively. All patients presented sustained improvement in Wexner Score and in quality of life questionnaire (in all scales of Fecal Incontinence Quality of Life Scale). Conclusions: Deoti's surgical flap with sphincteroplasty successfully reconstructs complex anatomical deformities of the perineum. Current questionnaires to assess fecal incontinence may not evaluate properly the anatomical result of the technique, thus we propose a visual scale. In addition, sphincteroplasty with Deoti's flap may have longer-term outcomes in functional results than sphincteroplasty alone. RESUMO Objetivos: A esfincteroplastia anal com retalho Deoti é um procedimento publicado recentemente para o tratamento de deformidade perineal grave. O objetivo deste estudo é relatar seis pacientes, analisando seus resultados em questionários de incontinência fecal e propondo uma nova escala para avaliar melhor o objetivo principal da nossa técnica, a reconstrução da anatomia perianal. Métodos: Seis pacientes foram submetidos à esfincteroplastia anal com retalho de Deoti e o acompanhamento foi realizado a cada seis meses. Os resultados funcionais e a qualidade de vida foram medidos pelas Escalas Wexner Score e FIQL, respectivamente. Resultados: Não houve falhas na rotação do retalho Deoti. A amostra apresentou medianas de 18,5 e 3,5 na Wexner Score, antes e depois da cirurgia, respectivamente. Na Escala FIQL, as medianas antes e depois da cirurgia são, respectivamente, 1,75 e 3,35 (Escala 1); 1,54 e 2,60 (Escala 2); 2,35 e 3,28 (Escala 3); 1,49 e 3,33 (Escala 4). Os valores de p foram 0,0173 para Wexner Score e 0,0260; 0,0411; 0,0368 e 0,0952 para Escalas 1; 2; 3 e 4 de FIQL, respectivamente. Todos os pacientes apresentaram melhora sustentada na pontuação de Wexner e no questionário de qualidade de vida (em todas as escalas do FIQL). Conclusões: O retalho de Deoti com esfincteroplastia reconstrói com sucesso as deformidades anatômicas complexas do períneo. Os questionários atuais para avaliar a incontinência fecal podem não avaliar adequadamente o resultado anatômico da técnica, por isso propomos uma escala visual. Além disso, a esfincteroplastia com retalho de Deoti pode apresentar resultados funcionais mais duradouros do que a esfincteroplastia isolada.

Disorders related to pelvic floor include urinary incontinence (UI), anal incontinence, pelvic organ prolapse, sexual dysfunction and pelvic pain. Because pelvic floor dysfunctions (PFD) can be diagnosed clinically, imaging techniques serve as auxiliary tools for establishing an accurate diagnosis. The objective is to evaluate the PFD in primiparous women after vaginal delivery and the association between clinical examination and three-dimensional ultrasonography (3DUS). A cross-sectional study was conducted in a in tertiary maternity. All primiparous women with vaginal deliveries that occurred between January 2013 and December 2015 were invited. Women who attended the invitation underwent detailed anamnesis, questionnaire application, physical examination and endovaginal and endoanal 3DUS. Crude and adjusted predictor factors for PFD were analyzed. Fifty women were evaluated. Sexual dysfunction was the most prevalent PFD (64.6%). When associated with clinical features and PFD, oxytocin use increased by approximately four times the odds of UI (crude OR 4.182, 95% CI 1.149–15.219). During the multivariate analysis, the odds of UI were increased in forceps use by approximately 11 times (adjusted OR 11.552, 95% CI 11.155–115.577). When the clinical and obstetrical predictors for PFD were associated with 3DUS, forceps increased the odds of lesion of the pubovisceral muscle and anal sphincter diagnosed by 3DUS by sixfold (crude OR 6.000, 95% CI 1.172–30.725), and in multivariate analysis forceps again increased the odds of injury by approximately 7 times (adjusted OR 7.778, 95% CI 1.380–43.846). Sexual dysfunction was the most frequent PFD. The use of forceps in primiparous women was associated with a greater chance of UI and pelvic floor muscle damage diagnosed by 3DUS.

The objective of this study was to determine the prevalence and diversity of gastrointestinal parasites in fecal samples from wild birds and mammals from the State of Paraná. In total, 220 stool samples were sent to Parasitic Diseases Laboratory of the Federal University of Paraná during 13 months (Jan/2013-Jan/2014). A total of 52.7% (116/220) of the animals were positive for cysts, oocysts, eggs and/or trophozoites. In birds, the positivity rate was 37.9% (25/66) and mammals was 59.1% (91/154). Strongyloidea superfamily eggs were observed in 37.3% (82/220) of the samples, Eimeria spp. in 10% (22/220), and Trichuris spp. in 4.5% (10/220). The most frequent mammal species were llamas (Lama glama), and dromedaries (Camelus bactrianus) with infection rate of 70.1% (54/77) and 60.8% (14/23), respectively. In other hand, cockatiels (Nymphicus hollandicus) and ring necks (Psittacula krameri), were the most researched birds, with infection rate of 20% (40/50) and 100% (6/6), respectively. A high prevalence of gastrointestinal parasites was observed in most of wildlife animals. Further investigations should be conducted focusing on parasite control strategies and the conservation measurements for harmonizing the human-animal interaction on the long-term, reducing associated health risks.

Resumo: O controle das endoparasitoses gastrintestinais em pequenos ruminantes tem sido tradicionalmente realizado por meio do uso indiscriminado dos anti-helmínticos, porém essa prática tem resultado em grande pressão de seleção de parasitas resistentes. Métodos seletivos (ex: FAMACHA/FMC e contagem de ovos nas fezes/OPG) e que apresentem boa sensibilidade para identificar os animais que necessitam receber o tratamento químico são importantes alternativas aos métodos tradicionais. O objetivo desse trabalho foi determinar a sensibilidade e a especificidade do método FMC, usado para detectar anemia causada por Haemonchus contortus em ovinos da raça Suffolk, em duas categorias de alta suscetibilidade; cordeiros lactentes e ovelhas durante a fase de lactação. A conjuntiva ocular de 42 cordeiros lactentes e 35 ovelhas em lactação foi avaliada usando o método FMC, em intervalos de 14 dias, durante cinco meses. O hematócrito (Ht) foi utilizado como padrão-ouro para avaliação clínica de anemia dos animais. Para o cálculo de sensibilidade e especificidade, diferentes critérios foram utilizados: animais classificados como 4 e 5 ou 3, 4 e 5 e anêmicos pelo Ht (teste positivo); animais classificados como 1, 2 e 3 ou 1 e 2 e não anêmicos pelo Ht (teste negativo). Três valores de corte para Ht (≤22%, ≤19% ou ≤15%) foram utilizados para confirmar a anemia. Entre os gêneros observados nas coproculturas, H. contortus (61,5%) e Ostertagiasp (21,3%) foram os mais prevalentes. Em ambas as categorias, a inclusão do FMC 3 como teste positivo, elevou a sensibilidade mas reduziu a especificidade do método. Quando o FMC 3 foi considerado anêmico, o percentual de falsos negativos foi próximo a zero, no entanto, houve aumento no número de tratamentos aplicados em animais não anêmicos (falso positivo). Durante as avaliações, a maior parte dos cordeiros (73%) e das ovelhas (53%) permaneceu nas categorias de FMC 1 e 2. Apenas 5% dos cordeiros e 8% das ovelhas foram classificados com os dois maiores graus de anemia (FMC 4 e 5). Os resultados indicam que o FMC pode ser utilizado para identificar os cordeiros lactentes e ovelhas em fase de lactação com sinais clínicos de anemia decorrentes da infecção por H. contortus. Para ambas as categorias, foi necessário incluir o FMC 3 como positivo para aumentar a sensibilidade do método; reduzindo o risco de morte de animais anêmicos não diagnosticados (falsos negativos). Abstract: The control of gastrointestinal parasites in small ruminants has traditionally involved the indiscriminate use of anthelmintic drugs that resulted in a high parasite selection pressure for anthelmintic resistance. Selective methods (ex.: FAMACHA/FMC and faecal egg count/EPG), which have good sensitivity to identify animals that need drug treatment, are important alternative methods for parasite control. The objective of this study was to determine the sensitivity and specificity of the FMC method to detect clinical anemia caused by Haemonchus contortus in two highly susceptible categories of Suffolk sheep; suckling lambs and lactating ewes. The ocular conjunctivae of 42 suckling lambs and 35 lactating ewes were evaluated using the FMC method at 14 days interval for five months. Hematocrit (Ht) served as the gold standard for anemia evaluation. To calculate the sensitivity and specificity of the FMC method, different criteria were adopted: animals classified as 4 and 5, or 3, 4 and 5, were considered to be anemic (positive test), and animals classified as 1, 2 and 3, or 1 and 2 were considered to be non-anemic (negative test). Three standard values of Ht (≤22%, ≤19% or ≤15%) were used to confirm anemia. Among the prevalent genera of helminths H. contortus (61.5%) and Ostertagia sp. (21.3%) were the most predominant species in the coproculture. For both categories, the inclusion of FMC 3 as a positive test increased the sensitivity but decreased the specificity of the method. When FMC 3 was included as anemic, the percentage of false negative was close to zero, but a greater number of treatments were applied to non-anemic animals (false positive). Most of the lambs (73%) and ewes (57%) remained in categories 1 or 2 throughout the trial. Only 5% of the lambs and 8% of the ewes were classified as the two major stages of anemia (4 and 5). The results indicate that the FMC is a safe method to be used in lambs and lactating ewes with clinical anemia from H. contortusinfection. For both categories, it was necessary to include FMC 3 as a positive condition to increase the sensitivity of the method and to reduce the risk of death of undiagnosed anemic animals (false negatives).

Os parasitas gastrintestinais causam enorme prejuízo econômico na bovinocultura, tanto nacional como mundial, ocasionado principalmente por Bunostumomsp., Cooperiasp. e Trichostrongylussp. O objetivo deste trabalho foi determinar a eficácia in vitro do extrato hidroalcoólico de Artemisia annua(H.7) frente a esses endoparasitas. O H.7 foi produzido com sete dias de percolação a 4ºC e posteriormente liofilizado. Com esse fitoterápico, realizaram-se testes de eclodibilidade de ovos (TEO) e de migração larvar em ágar (TMLA), com seis repetições, com concentrações crescentes (0,78 a 50mg/mL). Para analisar a composição química do fitoterápico, procedeu-se à marcha fitoquímica completa. No TEO, a eficácia variou de 94,08±2,58% na maior concentração a 15,67±0,97% na menor concentração. Já no TMLA os valores encontrados variaram de 90,05±0,55% a 4,12±0,46%. Nas análises fitoquímicas, foram encontrados diversos compostos com propriedades de combater os nematódeos, tanto direta como indiretamente. Os resultados obtidos nos testes in vitroevidenciam que o extrato produzido possui potencial de combater nematódeos gastrintestinais de bovinos. Novos estudos devem ser realizados buscando maximizar a eficácia do H.7 e de outras extrações obtidas a partir de A. annua, uma vez que foram demonstrados excelentes resultados em ambos os experimentos. Gastrointestinal parasites cause economic losses to the cattle production, in Brazil and worldwide, mainly caused by Bunostumom sp., Cooperia sp. and Trichostrongylus sp. The aim of this study was to determine the in vitro efficacy of hydroalcoholic extract of Artemisia annua (H.7) against these parasites. The H.7 was produced after 7 days of storage at 4°C and then lyophilized. With this herbal the egg hatch test (EHT) and larval migration inhibition (LMI) were performed,in six replicates with different concentrations (0.78 to 50mg/mL). To analyze the chemistry composition the complete phytochemical screening was done. In EHT efficiency ranged from 94.08±2.58% at the highest concentration to 15.67± 0.97% in the lowest concentration. In LMI test the values ranged from 90.05±0.55% to 4.12±0.46%. Phytochemical tests showed many chemical compounds with anthelmintic properties. The results obtained in biochemical tests together with those found in in vitro tests showed that the extract produced has the potential to combat intestinal nematodes of cattle. Further studies should be conducted to maximize the effectiveness of H.7 and other extractions from A. annua, because it demonstrated excellent results in both experiments.

RESUMO O número de pacientes com distúrbios funcionais intestinais em decorrência das operações para o tratamento do câncer retal tem aumentado durantes as últimas décadas. Alterações anatômicas e funcionais após a retirada do reto provocam aumento da frequência evacuatória, urgência evacuatória, evacuações múltiplas e incontinência para fezes e flatos, caracterizando a síndrome da ressecção anterior baixa ou LARS - "low anterior resection syndrome". Este artigo apresenta uma revisão geral do tema, com ênfase para conceitos atuais e aspectos fisiopatológicos de distúrbios funcionais do intestino após o tratamento cirúrgico do câncer retal. É fundamental que o cirurgião compreenda esses mecanismos, para melhor abordagem dos pacientes e restabelecimento da sua qualidade de vida.

Background The present study aimed to evaluate the possible acute oral toxicity of Baccharis trimera leaf dye as well as its antimicrobial activity. Method Organization for Economic co-operation and development (OECD) 423 was used to assess acute oral toxicity and as per protocol a dose of 2000 mg/kg of tincture was administered to Wistar rats, male and female, and observed for 14 days. Biochemical and hematological analyzes were performed with sample collected of rat. The dye was evaluated for antimicrobial activity by agar diffusion and microdilution methods, which allow to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) and antibiofilm potential. Results The results showed that there was no loss of animals and no significant changes in hematological and biochemical parameters after oral administration of 2000 mg/kg of tincture and was considered safe by the OECD, classified as category 5. The dyeing also showed an important antimicrobial activity against gram positive and gram negative bacteria also significantly decreased the microbial biofilm. Conclusion The tincture of B. trimera leaf when given orally once can be considered safe and has a relevant antimicrobial potential that should be elucidated in subsequent research.

Purpose: Anal incontinence is a very stigmatizing condition, which affects biopsychosocially the patient. It is a neglected, but quite common complication of obstetric and anorectal surgery, however it has treatment options. None of the treatment options have exceptional efficacy rates and still associated with risk of recurrence. The surgery techniques known are: anterior and posterior shortening procedure; post-anal repair; anterior elevator plasty and external sphincter plication; total pelvic floor repair and sphincter repair. None of them use a flap rotation of adipose tissue. The purpose is to propose a new surgery technique of anal sphincteroplasty, which uses flap rotation, for severe perineal deformity associated with anal incontinence. Methods: Patient with severe perineal deformity and anal incontinence treated with a new surgery technique of sphincteroplasty with flap rotation. Results: The severe perineal deformity was corrected with both esthetic and functional results. Anal continence measured by Wexner and Jorge assessment in a follow-up period of 2 years after the intervention. Pictures and video show esthetic and functional aspects. Conclusion: This is the first time that a flap rotation is used to treat a severe perineal deformity. And the technique presented promising outcomes, which allows perineum reconstruction that is similar to the original anatomy. Therefore, this technique is justified to better evaluate its efficiency and the impact on patients’ prognosis. Resumo: Objetivo: A incontinência anal é uma condição muito estigmatizante, que afeta biopsicossocialmente o paciente. É uma complicação negligenciada, mas bastante comum da cirurgia obstétrica e anorretal, no entanto, tem opções de tratamento. Nenhuma das opções de tratamento tem taxas de eficácia excepcionais e ainda está associada ao risco de recorrência. As técnicas cirúrgicas conhecidas são: procedimento de encurtamento anterior e posterior; reparação pós-anal; plástica do elevador anterior e plicatura externa do esfíncter; reparo total do assoalho pélvico e reparo do esfíncter. Nenhum deles utiliza uma rotação de retalho de tecido adiposo. O objetivo é propor uma nova técnica cirúrgica de esfincteroplastia anal, que utiliza a rotação de retalho, para deformidade perineal grave associada à incontinência anal. Métodos: Paciente com deformidade perineal grave e incontinência anal tratada com nova técnica cirúrgica de esfincteroplastia com rotação de retalho. Resultados: A deformidade perineal grave foi corrigida com resultados estéticos e funcionais. Continência anal medida pela avaliação de Wexner & Jorge em um período de seguimento de 2 anos após a intervenção. Imagens e vídeo mostram aspectos estéticos e funcionais. Conclusão: Esta é a primeira vez que uma rotação de retalho é usada para tratar uma deformidade perineal grave. E a técnica apresentou resultados promissores, o que permite a reconstrução do períneo semelhante à anatomia original. Portanto, esta técnica é justificada para melhor avaliar sua eficiência e o impacto no prognóstico dos pacientes.

Resumo O objetivo deste estudo foi avaliar a eficácia do extrato hidroalcoólico de Artemisia annua frente a oocistos de Eimeria sp. em camas contaminadas. O extrato foi produzido com 7 dias de percolação a 4°C, sendo posteriormente realizada a marcha fitoquímica; dosagem de fenóis totais, quantificação de artemisinina, ensaio antioxidante e teste de toxicidade. Para testar a atividade anticoccidiana, camas de aves compostas de cepilho de árvores foram contaminadas com 5000 oocistos. Foram formados quatro tratamentos, em triplicata, nos quais foram usadas diferentes concentrações, sendo G1: 12mg/mL, G2: 8mg/mL, G3: 4mg/mL e C-: água. Após a contaminação, foram aspergidos, 800 mL dos extratos nas diferentes concentrações sobre as camas e coletadas, em triplicatas, 10 cm2 de cada local, aleatoriamente, nos tempos: 0, 3, 6, 24, 48, e 72 horas após a aplicação. Nas análises fitoquímicas, foram evidenciados diversos compostos com propriedades antiparasitárias, como flavonoides e taninos. O fitoterápico continha 59,409±1,47μg/dL de artemisinina. O produto na concentração de 12mg.mL-1 apresentou eficácia entre 45,5 e 42,1%. Os resultados dos testes bioquímicos, juntamente com os encontrados no teste anticoccidiano, evidenciaram que o extrato produzido possui alto potencial para combater Eimeria sp. Abstract The aim of this study was to determine the efficacy of hydroalcoholic extract of Artemisia annua against oocysts of Eimeria sp. in contaminated poultry beds. The extract was produced after 7 days of storage at 4°C, which was used to perform the phytochemical screening; the artemisinin measurement; the total phenolic; antioxidant testing and toxicity test. To test the anticoccidial activity, the birds space composed of shaver trees, were contaminated with 5000 oocysts. Four treatment were formed, in triplicate, were used in different concentrations as G1: 12mg/mL, G2:= 9mg/mL, G3: 6mg/mL, and C-: water. After contamination 800 mL of the herbal at different concentrations were sprayed on the bed and collected, in triplicate, 10 cm2 each site, randomly, at times: 0, 3, 6, 24, 48, and 72 hours after application. In phytochemical analysis, were shown compounds with antiparasitic properties, such as flavonoids and tannins. The herbal contained 59.409±1.47mg/dL artemisinin. The product at a concentration of 12mg.mL-1 showed efficacy from 44.25 to 40.71%. The results of biochemical tests, with the in vitro test showed that the extract has produced high potential for combating Eimeria sp.

OBJECTIVE: To assess hematological and biochemical features of splenic effluent blood and their influence on the rise of hematological values after splenectomy. METHODS: we studied 20 patients undergoing surgical treatment for schistosomatic portal hypertension. We collected blood samples for CBC, coagulation, bilirubin and albumin in the splenic vein (perioperative) and peripheral blood (immediately pre and postoperative periods). RESULTS: the splenic blood showed higher values of red blood cells, hemoglobin, hematocrit, platelet count, total leukocytes, neutrophils, lymphocytes, monocytes, eosinophils and basophils, as well as reduction of laboratory coagulation parameters in relation to peripheral blood collected preoperatively. In the postoperative peripheral blood there was an increase in the overall leukocytes and in their neutrophil component, and decreased levels of basophils, eosinophils and lymphocytes. The other postoperative variables of complete blood count and coagulation tests were not different compared with the splenic blood. The albumin values were lower postoperatively when compared to preoperative and splenic blood. There were higher values of direct bilirubin in the postoperative period when compared with the preoperative and splenic blood. Postoperative indirect bilirubin was lower compared to its value in the splenic blood. CONCLUSION: hematological and biochemical values of splenic effluent blood are higher than those found in peripheral blood in the presence of schistosomal splenomegaly. However, the splenic blood effluent is not sufficient to raise the blood levels found after splenectomy.

Actinomycosis is a rare inflammatory disease caused by Actinomyces israelii. It can mimic many other diseases, such as malignant neoplasms or inflammatory bowel disease. We present a case in which actinomycosis simulated a colonic neoplasia.Actinomicose é uma doença inflamatória rara, causada pelo agente Actinomyces israelii. Pode mimetizar várias outras entidades, como neoplasias malignas e doenças inflamatórias intestinais. Relatamos aqui um caso, no qual a actinomicose simulou neoplasia cólica.

Considered the most abundant carnivore in the world, the domestic dog can cause negative impacts when he is present in forested areas. Dogs can develop different roles in the environment in which they live as hunter, shepherd, guardian, companion and even more affective relationships in which the dog is seen like a family member. These roles are closely linked to the way of life of their owners. In Caraguatatuba City, dogs that live in the vicinity of Serra do Mar, an important Atlantic Rainforest Conservation Unit, are commonly parasitized by Amblyomma ovale. From data obtained through three years of monitoring in three different areas around the Serra do Mar State Park Caraguatatuba City, it has been possible to generate results that help in understanding the causes and consequences of the dog presence in the surroundings of the forest as well as its participation in the epidemiology of riquetsiosis and rangeliosis. Comparing the lifestyle of the owners and the role of their dogs in the environment in which they are inserted, it has been possible to estimate the risk of transmission of Rickettsia parkeri to these dogs. In addition, through the molecular analysis of the A. ovale individuals collected on dogs and also in free life, it has been possible to infer about the population structure and genetics of this parasite in Serra do Mar, which is an important ecological corridor for the Atlantic Rainforest wild fauna. Considerado o carnívoro mais abundante do mundo, o cão doméstico pode causar impactos negativos quando presente em áreas florestadas. Cães podem desenvolver diferentes papéis no ambiente em que vivem desde caçador, pastor, guardião, companheiro e até mesmo relações mais afetivas em que o cão é visto como um membro da família. Estes papéis estão intimamente ligados ao modo de vida de seus proprietários. Em Caraguatatuba, cães que vivem no entorno da Serra do Mar, uma importante Unidade de Conservação da Mata Atlântica, são comumente parasitados por Amblyomma ovale. A partir de dados obtidos através de três anos de monitoramento em três diferentes áreas do entorno do Parque Estadual Serra do Mar Núcleo Caraguatatuba, foi possível gerar resultados que auxiliam no entendimento das causas e consequências da presença do cão no entorno da floresta e sua participação na epidemiologia da riquetsiose e rangeliose. Comparando o estilo de vida dos proprietários e o papel do cão no ambiente em que ele está inserido, foi possível estimar o risco de transmição de Rickettsia parkeri para estes cães. Além disso, através da análise molecular dos indivíduos de A. ovale coletados em cães e também coletados em vida livre, foi possível inferir sobre a estrutura e genética populacional deste parasita na Serra do Mar em Caraguatatuba, importante corredor ecológico para a fauna silvestre da Mata Atlântica.
