Introduction: Short Bowel Syndrome (SBS) is a rare gastrointestinal disorder associated with Intestinal Failure (SBS-IF) that leads to morbidity, mortality, and a burden on healthcare costs. Intestine Transplantation (IT) is a treatment option for patients with SBS-IF as it replaces the missing or diseased intestine and offers the potential for return to normal activities and intestinal function. This study aims to describe the clinical course and demographical and clinical characteristics of subjects with SBS-IF who underwent IT in Brazil., Methods: This retrospective observational study included all SBS-IF patients who underwent IT in two reference centers in Brazil from April 2011 to December 2021., Results: A total of 7 young male participants were included in the study. The most frequent underlying condition was surgical complications, followed by intestinal volvulus and incisional hernia. The most frequent indication for IT was a hepatic disease associated with total Parenteral Nutrition (PN). The main type of IT performed was intestine only. The median time from underlying condition to IT was 67.3 (16.5‒88.5) months. The mean (SD) number of yearly hospitalizations per patient was 0.5 (0.3). The most common reason for hospitalization was PN-related complications. Sixty exams were performed in-hospital and 53 in the outpatient setting., Conclusion: The findings of this study may be helpful to understand better the journey of patients with SBS-IF to IT in Brazil, providing real-world evidence to develop health policy guidelines and improve the quality of life of these patients., Competing Interests: Declaration of competing interest The authors declare the following conflicts of interest: YLB; MHMR; LH; RAAP: ADWL: APCSB; IC; GGR; FM; and LACA: Has acted as speaker in Takeda Distribuidora Ltda in medical-scope events.

Purpose: This study aimed to describe the behavioral patterns of data on cataract surgery performed in the Brazilian public health system before, during, and after the COVID-19 outbreak and estimate the setbacks generated by the pandemic to guide public policies., Materials and Methods: This was an observational, longitudinal, and descriptive epidemiological study based on data retrieved from the public health system's databases of cataract surgeries performed each year and in each region from 2015 to 2022., Result: In Brazil, compared with the average of the 5-years preceding the pandemic, a 23 % reduction in the number of cataract surgeries was observed in 2020, followed by a 21 % increase in 2021, compensating for the majority of patients that were not operated on. However, the worsening situation of blindness caused by cataracts due to the pandemic not be avoided in the Central-West region, where unrecovered cases continue to accumulate., Conclusion: The COVID-19 pandemic did not worsen the situation of cataract blindness in Brazil due to the efficacy of the measures taken by the government in resuming elective surgeries. However, the auhtors recommend that the distribution of resources for cataract surgeries should consider regional discrepancies based on epidemiological data., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2024 HCFMUSP.

The article "The impact of bleomycin deficit on survival in Hodgkin's lymphoma patients: A retrospective study" have presented the experience of AVD chemotherapy regimen in newly diagnosed Hodgkin's lymphoma (HL) in a single center in Brazil. Though being a small retrospective study, results from this study have provided the medical community a real-world data on HL in Brazil. ABVD has remained the standard of care for patients of newly diagnosed HL both in early and advance stages. Newer targeted molecules have also come for use in novel combinations with existing drugs. However, in a situation of temporary scarcity of bleomycin due to lack of supply during 2017 in Brazil led to use of incomplete ABVD regimen without bleomycin, i.e. AVD for HL. However, Soldi et al. utilized the opportunity to retrospectively study if the omission of bleomycin leads to subnormal treatment or unwarranted effects., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Introduction: We aim to provide better insights into the demographic, epidemiological, and seasonal characteristics of scorpion envenomation reported in the Rio Doce Valley, Brazil., Methods: We conducted this monocentric retrospective descriptive study with data on Investigation Forms of Accidents by Venomous Animals, only envenoming cases of scorpion stings, between January 1, 2017 and December 31, 2020, belonging to the compulsory notification system of the Municipal Hospital of Governador Valadares., Results: There were 3032 accidents, and the male-to-female ratio was 1.17:1 (male, 54%; females, 46%). Accidents occurred every month, but there was an increase in June, July, and October to January. In most cases, the time between the scorpion sting and medical care was between 1 and 3 h (n=1304; 43%). The most frequent clinical and systemic manifestations were pain at the bite site (94%) and vagal symptoms (7%). Cases were mild (n=2750, 91%), moderate (n=221, 7%), and severe (n=56, 2%). Children younger than 10 y constituted the most cases, 522 (17%). There was a significant difference between clinical severity and age (P<0.01). Ten patients developed acute pulmonary edema. Two 4-y-old children died. All severely envenomated patients as well as 74% and 2% of mild and moderately envenomated patients, respectively, received specific scorpion antivenoms., Conclusions: Scorpion envenomation is of greater severity in children aged <10 y. The clinical presentation includes mainly local pain associated with vagal symptoms. Accidents occur every month, but there was an increase in June, July, and October to January., (Copyright © 2023 Wilderness Medical Society. Published by Elsevier Inc. All rights reserved.)

Objectives: To analyze the rates of breast cancer survival among Black and White women according to age and stage at diagnosis., Study Design: A retrospective cohort study., Methods: The study examined women registered in the population-based cancer registry of Campinas in 2010-2014. The primary variable was the declared race (White or Black). Other races were excluded. Data were linked with the Mortality Information System, and missing information was accessed by active search. Overall survival (OS) was calculated by the Kaplan-Meier method, comparisons were done by chi-squared tests, and hazard ratios were examined by Cox regression., Results: The total numbers of new cases of staged breast cancer among Black and White women were 218 and 1522 cases, respectively. The rates of stages III/IV were 35.5% among White women and 43.1% among Black women (P = 0.024). The frequencies among White and Black women under 40 years old were 8.0% and 12.4% (P = 0.031), 19.6% and 26.6% (P = 0.016) for ages of 40-49 years, and 23.8% and 17.4% (P = 0.037) for ages of 60-69 years, respectively. The mean OS was 7.5 years (7.0; 8.0) among Black women and 8.4 years (8.2; 8.5) among White women. The 5-year OS was 72.3% among Black women and 80.5% among White women (P = 0.001). Black women had an age-adjusted risk of death that was 1.7 times higher (1.33; 2.20). The risk was 6.4 times higher for diagnoses in stage 0 (1.65; 24.90) and 1.5 times for diagnoses in stage IV (1.04; 2.17)., Conclusion: The 5-year OS for women with breast cancer was significantly lower among Black women than White women. Black women were more frequently diagnosed in stages III/IV, and their age-adjusted risk of death was 1.7 times higher. Differences in access to care may explain these differences., (Copyright © 2023 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.)

Background: People with severe mental illness have a mortality rate higher than the general population, living an average of 10-20 years less. Most studies of mortality among people with severe mental illness have occurred in high-income countries (HICs). We aimed to estimate all-cause and cause-specific relative risk (RR) and excess mortality rate (EMR) in a nationwide cohort of inpatients with severe mental illness compared with inpatients without severe mental illness in a middle income country, Brazil., Methods: This national retrospective cohort study included all patients hospitalised through the Brazilian Public Health System (Sistema Único de Saúde [SUS]-Brazil) between Jan 1, 2000, and April 21, 2015. Probabilistic and deterministic record linkages integrated data from the Hospital Information System (Sistema de informações Hospitalares) and the National Mortality System (Sistema de Informação sobre Mortalidade). Follow-up duration was measured from the date of the patients' first hospitalisation until their death, or until April 21, 2015. Severe mental illness was defined as schizophrenia, bipolar disorder, or depressive disorder by ICD-10 codes used for the admission. RR and EMR were calculated with 95% CIs, comparing mortality among patients with severe mental illness with those with other diagnoses for patients aged 15 years and older. We redistributed deaths using the Global Burden of Diseases, Injuries, and Risk Factors Study methodology if ill-defined causes of death were stated as an underlying cause., Findings: From Jan 1, 2000, to April 21, 2015, 72 021 918 patients (31 510 035 [43·8%] recorded as male and 40 974 426 [56·9%] recorded as female; mean age 41·1 (SD 23·8) years) were admitted to hospital, with 749 720 patients (372 458 [49·7%] recorded as male and 378 670 [50·5%] as female) with severe mental illness. 5 102 055 patient deaths (2 862 383 [56·1%] recorded as male and 2 314 781 [45·4%] as female) and 67 485 deaths in patients with severe mental illness (39 099 [57·9%] recorded as male and 28 534 [42·3%] as female) were registered. The RR for all-cause mortality in patients with severe mental illness was 1·27 (95% CI 1·27-1·28) and the EMR was 2·52 (2·44-2·61) compared with non-psychiatric inpatients during the follow-up period. The all-cause RR was higher for females and for younger age groups; however, EMR was higher in those aged 30-59 years. The RR and EMR varied across the leading causes of death, sex, and age groups. We identified injuries (suicide, interpersonal violence, and road injuries) and cardiovascular disease (ischaemic heart disease) as having the highest EMR among those with severe mental illness. Data on ethnicity were not available., Interpretation: In contrast to studies from HICs, inpatients with severe mental illness in Brazil had high RR for idiopathic epilepsy, tuberculosis, HIV, and acute hepatitis, and no significant difference in mortality from cancer compared with inpatients without severe mental illness. These identified causes should be addressed as a priority to maximise mortality prevention among people with severe mental illness, especially in a middle-income country like Brazil that has low investment in mental health., Funding: Bill and Melinda Gates Foundation, Fundação de Amparo a Pesquisa do Estado de Minas Gerais, FAPEMIG, and the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior-Brasil., Competing Interests: Declaration of interests All other authors declare no competing interests., (Copyright © 2022 The Author(s).

Objectives: This study aimed at identifying the sociodemographic and first treatment characteristics affecting time-to-treatment initiation (TTI) of patients with cutaneous melanoma assisted by the Brazilian Unified Health System (SUS)., Study Design: Retrospective observational study using cutaneous melanoma cases recorded in the Brazilian Hospital-Based Cancer Registries (HBCR)., Methods: A total of 12,783 cutaneous melanoma cases were included in the analysis. Based on the legislation, TTI in Brazil is 60 days; therefore, the cohort was dichotomized into TTI within 60 days and over. The association among variables was evaluated through the Chi-squared test. Kaplan-Meier method and log-rank hypothesis test were used to determine the probability of initiating treatment within 60 days. Cox proportional hazards regression model was used for multivariate analysis., Results: Median TTI was 28 days (95% CI, 25-29). First treatment in SUS provided more than 60 days after diagnosis (34.8%) was associated with females; low level of formal education; living or getting treatment in northern Brazil; being diagnosed in SUS and treated at different healthcare facilities, in addition to starting treatment with radiotherapy or systemic therapy. There were no significant differences in access to health care before and after the enactment of the 60-day law., Conclusion: Increased TTI for cutaneous melanoma is associated with sociodemographic and first treatment characteristics in Brazil; approximately one-third of cases did not have access to first treatment within the period established by law. Receiving the diagnosis and treatment at different healthcare facilities (transitions in care) is the main independent factor associated with TTI longer than 60 days., (Copyright © 2022 The Royal Society for Public Health.

Pythiosis is an endemic disease in northeastern Brazil and we now report the epidemiological, clinical and pathological findings in a retrospective study of naturally occurring cases in domestic animals. From January 1985 to December 2020, the Laboratory of Animal Pathology of the Federal University of Campina Grande examined 13,542 tissue samples from necropsies and biopsies. Among these samples, 306 were diagnosed as pythiosis: 195 cases in horses, 75 in sheep, 19 in dogs, six in mules, four in cattle, three in cats, two in goats, one in a donkey and one in an ostrich. Affected equids had lesions in the skin, mammary glands and nasal cavities. Affected sheep had cutaneous, nasal and digestive lesions while cattle and goats had cutaneous lesions. Carnivores developed lesions, mainly in the alimentary tract, of sufficient severity to cause death or result in euthanasia. The single affected bird had lesions in the alimentary tract and surgical excision resulted in remission. The disease had a long and life-threatening clinical course in most affected species but resolved spontaneously in cattle. Clinical signs were directly related to the location of the lesions, which were invariably characterized by chronic inflammation associated with intralesional hyphae. Veterinary clinicians and pathologists should be familiar with the clinicopathological features of pythiosis and the wide range of susceptible animal species., (Copyright © 2022 Elsevier Ltd.

Objectives: We aimed to characterize the profile of patients diagnosed with leprosy relapse and understand the influence of different multidrug therapy (MDT) treatments and initial disease presentation., Methods: This retrospective study included patients diagnosed with leprosy relapse at a referral center in Brazil from 2013 to 2018. We analyzed their clinico-epidemiologic characteristics, laboratory data, and bacilloscopic tests. Survival analysis was used to determine the time elapsed until relapse according to the previous treatment and clinical forms of the disease., Results: A total of 126 cases of relapse were analyzed, which comprised 11.89% (126/1059) of the cases. The median time elapsed until a relapse was 10 years, and most patients had previously undergone 12 doses of MDT (40.48%; 51/126). Undergoing 24 doses of MDT was associated with a better prognosis regarding relapse over time compared with 6 or 12 doses of MDT therapy. Most cases of relapse were classified as multibacillary (96.03%; 121/126)., Conclusion: The incidence of relapse was greater than observed in other studies. The high percentage of multibacillary patients who had negative bacillary indices demonstrated that the bacillary index cannot be considered to be an essential criterion for relapse, especially concerning making an early diagnosis., Competing Interests: Declaration of interests None of the authors report any competing interests., (Copyright © 2022 The Authors.

The aim of this study was to evaluate the prevalence and antimicrobial resistance profile of bacterial species isolated from infected sites of canines. All samples were collected from canine patients who received clinical or surgical care at the veterinary teaching hospital between March 2016 and November 2017. The samples were analyzed in a private pathology laboratory. A descriptive analysis of 295 antimicrobial susceptibility test reports was performed. Staphylococcus spp. (104/295 [35.25%]), Escherichia coli (100/295 [33.90%]), Proteus spp. (44/295 [14.92%]), Pseudomonas spp. (25/295 [8.47%]), and Klebsiella spp. (20/295 [6.78%]) were more frequently isolated, and a high incidence of multidrug resistance was observed (69,83% [206/295]). Methicillin-resistant Staphylococcus spp. accounted for 33% (33/100) of the Staphylococcus strains. Enterobacteriaceae cefotaxime resistance constituted 22.82 ± 4.49% and Enterobacteriaceae imipenem resistance constituted 5% (1/20) for Klebsiella spp., 5% (5/100) for E coli, and 6.82% (3/44) for Proteus spp. Pseudomonas spp. strains accounted for 8% (2/25) of imipenem resistance and 45.45% (10/22) of polymyxin B resistance. Our findings revealed a high rate of multidrug-resistant bacteria involvement in the infectious process of dogs. From the perspective of the One Health scenario, our results showed alarming data, given the high risk of resistant-strain dissemination between animals, owners, and healthcare professionals. There is an urgent need for strategies to control and prevent the evolution of new multidrug-resistant bacteria in veterinary hospitals. It is also crucial to understand and emphasize the role of veterinary professionals in this public health battle., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Purpose: To identify the most prevalent types of complications associated with orthognathic surgery and its possible risk factors., Methods: This study was a retrospective investigation of records of 485 patients who underwent orthognathic surgery between 2008 and 2014 at the Oral and Maxillofacial Surgery Service at the Federal University of Paraná, Curitiba, Brazil. Types of complications were recorded. Independent variables such as sex, age, duration of surgery and hospitalization, number of surgeries, surgical site, and types of osteotomy performed were evaluated. Complications were also evaluated based on the treatment according to the Clavien-Dindo Classification. Data were submitted to statistical analysis with a significance level of 0.05., Results: A total of 93 complications were reported (19.2%), including postoperative malocclusion, hemorrhage, inferior alveolar nerve injury, bad split, and infection. Complications were more common in men (p = 0.029). The number of complications was higher in surgeries that took more time to perform (p < 0.05) when the entire sample was taken into consideration. The prevalence of complications was related to a higher number of procedures per surgery (p = 0.019). Complications were more frequent in mandibular procedures (p = 0.010), particularly in bilateral sagittal split osteotomies (p < 0.001). Related to treatment, Clavien-Dindo grade I complications were the most frequent (72.04%). There was no association between sex, age, surgery duration, length of hospitalization, or surgical site with complication grades according to the Clavien-Dindo classification (p ≥ 0.05)., Conclusion: Postoperative malocclusion, hemorrhage, inferior alveolar nerve injury, bad split and infection are the most prevalent complication in orthognathic surgery. They seem to be related to sex, duration of surgery, number of surgeries, surgical site, and the type of osteotomy performed. With these in mind, it is possible to explain to the patient the different levels of severity of complications related to the surgery., (Copyright © 2019 European Association for Cranio-Maxillo-Facial Surgery.

Babesiosis is a tick-borne hemolytic disease caused by intraerythrocytic protozoan parasites of the genus Babesia. The present study describes epidemiological, clinical, and pathological features of cases of bovine babesiosis diagnosed over the last two decades in the state of Mato Grosso do Sul in central-western Brazil. Examination of a total of 5298 bovine samples resulted in a definitive or presumptive diagnosis of babesiosis in 41 cases from 33 outbreaks. Babesia bovis was the most common causal agent of bovine babesiosis, and animals of all ages were affected. Zebu cattle, which are more frequent in the study region than are taurine cattle, were the cattle most often affected. Although zebu cattle have been claimed to be highly tolerant, the present findings show that they can develop severe illness and die due to Babesia spp. infection. The disease was diagnosed almost every year over the time period covered in this study (1995-2017). However, the number of cases of bovine babesiosis diagnosed was low compared to the total number of cases reviewed. Veterinary practitioners that work on cattle farms should to be able to diagnose the disease in its early stages so that treatment can be initiated promptly and economic losses can be minimized., (Copyright © 2018 Elsevier GmbH.

Objective: Mohs micrographic surgery is a specialized surgical procedure used to treat skin cancer. The purpose of this study was to better understand the profile of the patients who underwent the procedure and to determine how histology might be related to complications and the number of stages required for complete removal., Methods: The records of patients who underwent Mohs micrographic surgery from October 2008 to November 2013 at the Dermatology Division of the Hospital of the Campinas University were assessed. The variables included were gender, age, anatomical location, histology, number of stages required and complications., Results: Contingency tables were used to compare the number of stages with the histological diagnosis. The analysis showed that patients with superficial basal cell carcinoma were 9.03 times more likely to require more than one stage. A comparison between complications and histological diagnosis showed that patients with superficial basal cell carcinoma were 6.5 times more likely to experience complications., Conclusion: Although superficial basal cell carcinoma is typically thought to represent a less-aggressive variant of these tumors, its propensity for demonstrating "skip areas" and clinically indistinct borders make it a challenge to treat. Its particular nature may result in the higher number of surgery stages required, which may, as a consequence, result in more complications, including recurrence. Recurrence likely occurs due to the inadequate excision of the tumors despite their clear margins. Further research on this subtype of basal cell carcinoma is needed to optimize treatments and decrease morbidity.

A retrospective study was conducted to assess the role of initial serum (1,3)-β-d-glucan (BDG) values in predicting mortality in proven candidaemia. The study was conducted in two large teaching hospitals in Italy and Brazil. From January 2009 to June 2014, all patients with proven candidaemia who underwent a BDG test within 96 hours before or after the first positive blood culture were included in the study. The primary end point was 28-day mortality, with the role of initial BDG being assessed by univariate and multivariate analyses. A total of 104 patients met the inclusion criteria. Overall, the crude 28-day mortality was 30% (31/104). In the final multivariate model, an initial BDG of >287 pg/mL (odds ratio (OR) 4.40, 95% confidence interval (CI) 1.56-12.39, p 0.005), haemodialysis (OR 4.33, 95% CI 1.24-15.17, p 0.022) and a Pitt score of ≥ 2 (OR 4.10, 95% CI 1.24-13.54, p 0.021) were significant predictors of 28-day mortality. The >287 pg/mL cutoff predicted 28-day mortality with 65% sensitivity and 70% specificity. Centre of enrolment (p for interaction 0.012), haemodialysis (p for interaction 0.062) and timing of BDG test of more than 24 hours before or after the positive culture (p for interaction 0.143) appeared to interact with BDG's ability to predict mortality. Although not statistically significant, the last two of these interactions might partially explain why BDG's ability to predict mortality was present only in the Italian cohort., (Copyright © 2015 European Society of Clinical Microbiology and Infectious Diseases.

Objective: To analyze how elderly patients with glioblastoma are managed in Brazil., Material and Methods: We identified 30 patients aged ≥ 65 years treated between 2003 and 2011 at Albert Einstein Hospital in Sao Paulo. We retrospectively reviewed medical records to obtain data on clinical variables, treatment and outcomes. Overall survival (OS) was evaluated using Kaplan-Meier methods and compared using a Wilcoxon log-rank test., Results: The median age was 73 years. The majority of patients (73.2%) underwent surgical intervention. Following surgery, 80% received radiotherapy (RT), and of those, 79.2% were treated with concurrent temozolomide (TMZ). The median progression free survival and OS were 5 and 10.6 months, respectively. Patients with a KPS ≥ 70 had a median OS of 16.2 months, compared to 6.4 months for those with a KPS <70 (p=0.032). For those patients in whom biopsy only was performed, the median OS was 5.3 months, as compared to 7.8 months for those who underwent partial resection and 18.6 months for those treated with gross total resection (p=0.021). A longer survival was found among patients who received RT versus those who did not (11 months vs. 1 month, p=0.003), as well as for those treated with chemoradiation (13.6 months vs. 6.4 months, p<0.0001)., Conclusions: This study brings new information about the management of elderly patients with glioblastoma in Brazil. Our data may suggest that elderly patients who undergo cytoreductive surgery and adjuvant RT with concurrent TMZ can do better than those with less aggressive treatment., (© 2013 Elsevier Ltd.

The objective of this study is to analyze patterns of facial fractures in children treated at the Service of Oral and Maxillofacial Surgery of the Vila Penteado General Hospital (HGVP), in São Paulo, Brazil, in a period of 3 years. Between May 2008 and April 2011 the authors reviewed 110 records of patients under 12 years old with facial fractures. The following parameters were evaluated: age and sex distribution, aetiology of trauma, incidence and type of fractures, monthly distribution and treatment modality. Male-to-female ratio was 1.8:1, and the mean age was 8.13. The majority of the involved patients were aged between 6 and 12 years. The most prevalent cause was fall (58%) and nasal fractures were the most common type of fracture (69%). Monthly distribution was similar in all seasons. Of 110 patients, 69 (62%) were treated conservatively. The incidence of facial fractures in the area of study is high. The high incidence of nasal fractures should be a warning to maxillofacial surgeons, so that they are not overlooked. Safety programs should be installed in Brazil to increase public awareness and to decrease morbidity resulting from paediatric trauma., (Copyright © 2012 European Association for Cranio-Maxillo-Facial Surgery.

Objectives: A number of complications exist with invasive mechanical ventilation and with the use of and withdrawal from prolonged ventilator support. The use of protocols that enable the systematic identification of patients eligible for an interruption in mechanical ventilation can significantly reduce the number of complications. This study describes the application of a weaning protocol and its results., Methods: Patients who required invasive mechanical ventilation for more than 24 hours were included and assessed daily to identify individuals who were ready to begin the weaning process., Results: We studied 252 patients with a median mechanical ventilation time of 3.7 days (interquartile range of 1 to 23 days), a rapid shallow breathing index value of 48 (median), a maximum inspiratory pressure of 40 cmH(2)0, and a maximum expiratory pressure of 40 cm H(2)0 (median). Of these 252 patients, 32 (12.7%) had to be reintubated, which represented weaning failure. Noninvasive ventilation was used postextubation in 170 (73%) patients, and 15% of these patients were reintubated, which also represented weaning failure. The mortality rate of the 252 patients studied was 8.73% (22), and there was no significant difference in the age, gender, mechanical ventilation time, and maximum inspiratory pressure between the survivors and nonsurvivors., Conclusions: The use of a specific weaning protocol resulted in a lower mechanical ventilation time and an acceptable reintubation rate. This protocol can be used as a comparative index in hospitals to improve the weaning system, its monitoring and the informative reporting of patient outcomes and may represent a future tool and source of quality markers for patient care.

Records from 6,706 necropsy examinations of cattle performed over a 45-year period were surveyed and 586 cases of neoplasia were identified. The organ system most frequently affected by neoplastic disease (n=139 cases) was the alimentary tract. This finding was attributed to a high incidence of squamous cell carcinoma of the upper alimentary tract associated with the chronic ingestion of bracken fern (Pteridium aquilinum). This carcinogenic plant was also associated with a relatively high incidence (n=35 cases) of urinary bladder tumours (enzootic haematuria). Tumours of the alimentary tract were followed, in decreasing order of frequency, by tumours of the skin and subcutis (n=129 cases), haemopoietic tissue (n=101 cases), the eye and periorbital tissues (n=88 cases), the urinary system (n=44 cases), the female reproductive system (n=21 cases), the endocrine system (n=16 cases), the liver and pancreas (n=12 cases), the nervous system (n=6 cases), the respiratory system (n=6 cases) and the mammary gland (n=1 case). The primary anatomical location of 16 tumours was undetermined., (Copyright © 2010 Elsevier Ltd. All rights reserved.)

Objective: The objective of this study was to analyze the frequency and distribution of odontogenic tumors in Fortaleza, Brazil, and compare the findings with those reported in the literature., Study Design: A total of 6231 oral lesions retrieved from 5 anatomic pathology services in Fortaleza, Brazil, over a 5-year period, were reviewed. In addition, the literature was searched for studies on odontogenic tumors (OTs) according to the 2005 WHO classification., Results: Within the total 6231 oral lesions, 185 (2.97%) were OTs, all benign. OTs presented a female predilection, with a male:female ratio of 0.62:1.00. These neoplasms occurred over a wide range of ages (1 to 78 years), with a mean of 30.5 years. Ameloblastomas, keratocystic odontogenic tumors, and odontomas were the most frequent OT types., Conclusions: OTs are rare neoplasms and appear to show geographic variations. In Fortaleza, Brazil, they are more common in female patients, with ameloblastoma followed by keratocystic odontogenic tumors as the most frequent OTs., (Copyright © 2011 Mosby, Inc.

An evaluation was made of the clinical and hematological aspects of 115 dogs infected naturally by Hepatozoon sp. and treated at the Hospital School of the Faculty of Veterinary Medicine in Uberlândia, MG, Brazil. Of the 115 dogs for whom peripheral blood films were evaluated, 89 (77.39%) presented parasitemia by Hepatozoon sp. solely, while 26 (22.61%) had combination of Hepatozoon sp., Babesia sp. and Ehrlichia sp. Young male dogs less than a year old, of undefined breed (UB), were the most commonly affected. Thirty-nine (33.92%) of the dogs were asymptomatic while 76 (66.08%) presented varied clinical symptoms, the most frequent being anorexia, pulmonary alterations, hyperthermia, pale mucosae, apathy and/or prostration, and diarrhea. The majority of hematological alterations were normochromic-normocytic anemia, leukocytosis, neutrophilia, and nuclear deviation of neutrophils to the left (NDNL). The findings of this study confirm that Hepatozoon sp. causes clinical and hematological alterations of varied intensity, which, albeit not specific to canine hepatozoonosis, reinforce the notion that the discovery of the agent in dogs, even with low parasitemia, should be taken into consideration.

Gingival cyst of the adult (GCA) is a rare entity and comprises around 0.3% of all odontogenic cysts. Due to its rarity, there are a few retrospective studies on it. Therefore, the aim of this study was to present casuistic data of a 20-year retrospective study performed in a Brazilian oral pathology reference center. All cases diagnosed as gingival cyst of the adult in the last 20 years were retrieved from the files of the Oral Pathology Service. Data from the lesions and patients were tabulated and presented descriptively. From a total of 68,229 oral biopsies, 7,023 were odontogenic cysts, and among these only 20 cases were diagnosed as gingival cyst of the adult, resulting in the largest series of gingival cyst of the adult, from a single center, in the last 15 years. Most cases occurred in women, and although 53% affected the anterior mandible, 40% occurred in the anterior maxilla, which contrasts with the previous literature. Despite being a rare lesion GCA should be considered in the clinical differential diagnosis of gingival lesions presenting either in the maxilla or mandible., (Copyright © 2019 European Association for Cranio-Maxillo-Facial Surgery.

Background: Statins are the main strategy to reduce dyslipidemia-related cardiovascular risk. Nevertheless, there is scarce evidence on the real-world statins use in primary care settings in low-middle-income countries., Objective: We conducted a cross-sectional retrospective study using anonymized data routinely collected by community health workers in Brazil aimed to evaluate statin use and associated factors in a primary prevention population with cardiovascular risk enhancers., Methods: Study population consisted of adults with hypertension, diabetes, and/or dyslipidemia. The primary and secondary outcomes were the proportion of individuals self-reporting statins use on any dose and high-dose statins/high-intensity lipid-lowering therapy (LLT), respectively., Results: Of the 2,133,900 adult individuals in the database, 415,766 (19.5%) were included in the study cohort. From this cohort, 89.1% had hypertension, 28.9% diabetes, and 5.5% dyslipidemia. The mean age was 61.5 (standard deviation 14.5) years, 63.4% were female, and 61.0% were of mixed-race. Only 2.6% and 0.1% of individuals self-reported the use of statins and high-dose statins/high-intensity LLT, respectively. Older age (odds ratio [OR] 1.96; 95% confidence interval [CI] 1.88, 2.05, p < 0.001), living in the South region of Brazil (OR 4.39; 95% CI 3.97, 4.85, p < 0.001), heart failure (OR 2.60; 95% CI 2.33, 2.89, p < 0.001), chronic kidney disease (OR 1.49; 95% CI 1.35, 1.64, p < 0.001), and anti-hypertensive medications use (OR 4.38; 95% CI 4.07, 4.71, p < 0.001) were independently associated with statin use., Conclusion: In a real-world evidence study analyzing data routinely collected in a digitized primary care setting, we observed a very low use of statins in a primary prevention population with cardiovascular risk enhancers in Brazil. Socio-demographic factors and co-morbidities were associated with higher statins use rates., (Copyright © 2024. Published by Elsevier Inc.)

Objectives: In 2020, Brazil experienced two concurrent public health challenges related to respiratory disease: wildfires and increased mortality due to the coronavirus (COVID-19) pandemic. Smoke from these wildfires contributed to a variety of air pollutants, including fine particulate matter (PM 2.5 ). The present study aims to investigate the effects of environmental and socio-economic factors on COVID-19 hospitalisation in the Pantanal., Study Design: Ecological retrospective study., Methods: We applied a multilevel negative binomial model to relate monthly hospitalisation data with environmental variables., Results: We showed that monthly PM 2.5 concentration levels had the greatest influence on the increase in hospitalisations by COVID-19 in the elderly (23 % increase). The Gini index, a coefficient that reflects income inequalities, also had a positive association with COVID-19 hospitalisations (18 % increase). Higher temperatures and humidity were protective factors, showing a 15 % and 14 % decrease in hospitalisations, respectively. The results of the present study suggest that high PM 2.5 exposure contributed to the increase in COVID-19 hospitalisations, as did the social inequalities of each municipality., Conclusions: The present study highlights the importance of gathering evidence supported by multiple information sources to guide decision-making and identify populations needing better public health systems., (Copyright © 2023 The Royal Society for Public Health.

Objectives: This study aimed to spatiotemporally analyze the profile of influenza-like illness (ILI) outbreaks in the state of São Paulo, Brazil, between 2020 and 2022., Study Design: This was a cross-sectional retrospective study., Methods: Outbreaks of ILI with final diagnoses of COVID-19, influenza, or other respiratory viruses (ORVs) recorded between January 2020 and November 2022, obtained from the Notifiable Diseases Information System (SINAN NET) Outbreak module, were analyzed. Kernel density estimates and Getis-Ord Gi∗ statistics were performed to identify spatial clusters., Results: A total of 13,314 ILI outbreaks were identified, involving 130,568 cases and 2649 deaths. Of these, 104,399 (80%) were confirmed as COVID-19, 15,861 (12%) were confirmed as ORV, and 10,308 (8%) were confirmed as influenza. The year 2021 had the highest number of outbreaks and cases. Schools recorded the most outbreaks and cases, followed by long-term care facilities for older adults (LTCs). The highest average number of cases per outbreak and the highest attack rates occurred at social gatherings and prisons. Prisoners were three times more likely to contract COVID-19 during outbreaks than people in other institutions. The highest hospitalization and mortality rates for all virus types occurred in the LTC group. The occurrence and intensity of outbreaks were highly heterogeneous among the different institutions after the introduction of new SARS-CoV-2 variants in the state., Conclusions: ILI outbreaks were not randomly distributed; they clustered in specific areas. Transmissibility varied among different institutions with different responses to the COVID-19 pandemic. These results can be used as a basis for prioritizing actions and allocating resources during future pandemics., (Copyright © 2023 The Royal Society for Public Health. Published by Elsevier Ltd.

Objectives: This study aimed to measure the hospitalization costs for suspect or confirmation cases of COVID-19 and aggregate knowledge in the costing process for future research on related topics., Methods: A cost calculation model was applied using absorption costing technique. Cost was allocated into 2 main groups: hospitalization and personnel. The cost analysis considers the hospital perspective. This is a retrospective study whose data were collected between April and September 2020, equivalent to the first wave of the disease in Brazil. This research uses data from Hospital Information System, Brazilian Unified Health System (SUS) Cost Calculation and Management System, and SUS Hospital Information System., Results: The average total cost per hospitalization was US$11 260 (R$63 504) for patients suspect or confirmed by COVID-19, and considering only detectable cases, the value was US$17 178 (R$96 886). The profile of hospitalized patients was male (51%), with a mean age of 59 years, white ethnicity (64%), and average length of stay of 9 days., Conclusions: The amount approved by SUS for remuneration of hospitalizations by COVID-19 proved to be insufficient to cover the calculated costs. The results of this study collaborate to measure the expenditure of hospital institutions with COVID-19 hospitalizations, contribute as a parameter for health managers to identify whether the values attributed to hospitalization by COVID-19 by the SUS are adequate to cover all costs involved, and provide lessons learned on costs to the public health system in the event of new pandemics., (Copyright © 2022 International Society for Health Economics and Outcomes Research.

In Malignant Hilar Biliary Stricture (MHBS) palliative biliary drainage is a frequent strategy, improving the quality of life, reducing pruritus, loss of appetite and relieving cholangitis. The endoscopic approach is an effective, although challenging procedure. This study aimed to evaluate technical and clinical success rates of biliary drainage by ERCP. This is a retrospective study including all patients with MHBS referred to Instituto do Cancer do Hospital de São Paulo (ICESP) submitted to biliary drainage by ERCP, between January 2010 and December 2017. Multivariable logistic regression was performed to evaluate predictors of clinical failure, as total bilirubin levels, Bismuth classification, number of hepatic sectors drained and presence of cholangitis. In total, 82 patients presenting unresectable MHBS were included in this study. 58.5% female and 41.5% male, with a mean age of 60±13 years. Bismuth classification grades II, IIIA, IIIB and IV were noted in 23.2%, 15.9%, 14.6% and 46.3%, respectively. Technical and clinical success was achieved in 92.7% and 53.7% respectively. At multivariable logistic-regression analyses, Bismuth IV strictures were related to higher clinical failure rates when compared to other strictures levels, with an Odds Ratio of 5.8 (95% CI 1.28‒20.88). In conclusion, endoscopic biliary drainage for malignant hilar biliary stricture had a high technical success but suboptimal clinical success rate. Proximal strictures (Bismuth IV) were associated with poor drainage outcomes., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2022 HCFMUSP.

Background: Sphenoid wing meningiomas with cavernous sinus invasion (SWMCSI) are challenging tumors. The preservation of quality of life and cranial nerve function is one of the most relevant aspects of treating patients with SWMCSI., Methods: A retrospective study was conducted for surgery performed between 2008 and 2021, including 36 patients presenting with SWMCSI. The data from surgical intervention, Simpson grade of resection, tumor location, and morbimortality related to the surgery was reviewed. We examined the medical records, operative reports, radiologic examinations, and follow-up information., Results: The group comprised 29 women and 7 men with an average age of 61 years (range, 31-87 years). The mean follow-up period was 75 months (range, 1-170 months). Simpson grade I and II resections were obtained in 80% of cases. The meningiomas were World Health Organization (WHO) grade 1 in 94% of cases, WHO grade 2 in 3%, and WHO grade 3 in 3%. The overall mortality was 5.5%. Permanent cranial nerve deficits occurred in 8% of cases, transient cranial nerve deficits in 22%, cerebrospinal fistula in 16.5%, and hemiparesis in 2.7%. The recurrence/regrowth rate was 14% during the follow-up period. The Karnofsky Performance Status 100 and 90 was 92%., Conclusions: The surgical treatment of symptomatic SWMCSI is an effective treatment modality with low morbimortality and good long-term control of the disease. Visual impairment is the most common abnormality, affecting preoperative and postoperative quality of life of patients with SWMCSI. Training in the microsurgical laboratory is essential for safe surgical approaches in this area., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Accidents caused by scorpions are considered a neglected condition and represent a major health problem in most tropical countries, especially for children and elderly people. In Brazil, scorpionism is recurrent in the southeast region, mainly in the state of São Paulo, due to the progressive increase in scorpions found in urban habitats. Thus, our study aimed to provide better insights into the geographic and epidemiological characteristics of scorpion envenomation in São Paulo state and identify the environmental factors that are associated with these accidents. This is an ecological and retrospective study with secondary data on scorpion accidents in the state of São Paulo from 2008 to 2018 obtained from the Notifiable Disease Information System. The SatScan software was used to identify the higher- and lower-risk spatiotemporal clusters. A total of 145,464 scorpion sting cases were recorded in the state of São Paulo, between 2008 and 2018; there was a four-fold increase in the incidence rate. Accidents occurred more frequently in the spring season, wherein higher-risk clusters were in the north and northwest regions of the state. High temperatures, low precipitation, and poor natural vegetation are associated with higher risk areas. Our study mapped vulnerable areas for scorpion accidents that can aid in the design of efficient public health policies, which should be intensified during the spring season., (Copyright © 2022 Elsevier B.V.

Objective: The purpose of this multicenter retrospective study was to report the clinical and radiologic features of 92 glandular odontogenic cysts (GOCs) diagnosed over a 20-year period., Study Design: Histologically confirmed cases of GOC were retrospectively reviewed from 4 oral pathology laboratories in South Africa and Brazil to categorize the clinical and radiologic spectrum of GOCs., Results: The mean age of patients was 46 years (range 17-87) with a male-to-female ratio of 1.2:1. GOCs had a mandibular predilection (68%), with 42% of all cases located anteriorly. Additionally, 42% of cases crossed the midline. Radiologically, most lesions were unilocular (53%) and uniformly radiolucent (97%), with well-demarcated borders (93%). Cortical expansion (62%), loss of cortical integrity (71%), and maxillary sinus (67%) and nasal cavity encroachment (72%) were common findings. Significant differences in lesions between the 2 countries were discovered in sex predilection, clinical signs and symptoms, and lesion locations within the mandible and maxilla., Conclusion: GOCs present with a wide spectrum of clinical and radiologic features, ranging from cysts with typical GOC-like presentations to more aggressive lesions. The need for advanced imaging in the surgical planning of GOCs exhibiting radiologic signs of aggression is justified based on the high recurrence rate., (Copyright © 2021 Elsevier Inc.

Background: The inferior vena cava is the most frequently injured vascular structure in penetrating abdominal trauma. We aimed to review inferior vena cava injury cases treated at a limited resources facility and to discuss the surgical management for such injures., Methods: This was a retrospective study of patients with inferior vena cava injuries who were treated at a single center between January 2011 and January 2020. Data pertaining to the following were assessed: demographic parameters, hypovolemic shock at admission, the distance that the patient had to be transported to reach the hospital, affected anatomical segment, treatment, concomitant injuries, complications, and mortality. Non-parametric data were analyzed using Fisher's exact, Chi-square, Mann-Whitney, or Kruskal-Wallis test, as applicable. The Student's t-test was used to assess parametric data. Moreover, multiple logistic regression analyses (including data of possible death-related variables) were performed. Statistical significance was set at P <0.05., Results: Among 114 patients with inferior vena cava injuries, 90.4% were male, and the majority were aged 20-29 years. Penetrating injuries accounted for 98.2% of the injuries, and the infrarenal segment was affected in 52.7% of the patients. Suturing was perfomed in 69.5% and cava ligation in 29.5% of the patients, and 1 patient with retrohepatic vena cava injury was managed non-operatively. The overall mortality was 52.6% with no case of compartment syndrome in the limbs. A total of 7.9% of the patients died during surgery., Conclusion: The inferior vena cava is often injured by penetrating mechanisms, and the most frequently affected segment was the infrarenal segment. A higher probability of death was not associated with injury to a specific anatomical segment. Additionally, cava ligation was not related to an increased probability of compartment syndrome in the leg; therefore, prophylactic fasciotomy was not supported., (Copyright © 2021.

Purpose: This study aimed to review the cases of giant adenomas that were operated on from 2012 to 2020 and to analyze the epidemiological profile, complications, and resection rates using the transseptal/transnasal endoscopy technique. We also compared the results with data from revised literature., Methods: This is an observational, retrospective study includes a review of the medical records of 26 patients diagnosed with giant adenomas (diameter > 4 cm or volume >10 cm 3 ) who underwent 28 surgical procedures., Results: Of the 57 patients operated for pituitary adenoma, 26 (50.8%) had giant adenomas. The mean volume was 17.28 cm 3 (95% confidence interval [CI], 8.3359-26.2241). Moreover, 64.28% of the patients were graded Knosp 3 (p < 0.0001). Most cases were of nonsecretory adenomas (88.46%). Visual impairment was present in 89.2% of the patients and hormonal deficit and headache affected 53.5% of them. The visual impairment improved in 60% of the patients. The most common surgical complication was cerebrospinal fluid fistula (10.71%). Tumor resection > 90% was achieved in 53.56% of the cases, and the mean resection rate was 78.36% (95% CI, 71.316-87.956)., Conclusions: The endoscopic endonasal technique is a good treatment option for giant adenomas, showing satisfactory optic apparatus decompression rates and a low incidence of complications when performed by surgeons with expertise in this approach., (Copyright © 2022 Elsevier B.V.

Background: Minimally invasive radical trachelectomy has emerged as an alternative to open radical hysterectomy for patients with early-stage cervical cancer desiring future fertility. Recent data suggest worse oncologic outcomes after minimally invasive radical hysterectomy than after open radical hysterectomy in stage I cervical cancer., Objective: We aimed to compare 4.5-year disease-free survival after open vs minimally invasive radical trachelectomy., Study Design: This was a collaborative, international retrospective study (International Radical Trachelectomy Assessment Study) of patients treated during 2005-2017 at 18 centers in 12 countries. Eligible patients had squamous carcinoma, adenocarcinoma, or adenosquamous carcinoma; had a preoperative tumor size of ≤2 cm; and underwent open or minimally invasive (robotic or laparoscopic) radical trachelectomy with nodal assessment (pelvic lymphadenectomy and/or sentinel lymph node biopsy). The exclusion criteria included neoadjuvant chemotherapy or preoperative pelvic radiotherapy, previous lymphadenectomy or pelvic retroperitoneal surgery, pregnancy, stage IA1 disease with lymphovascular space invasion, aborted trachelectomy (conversion to radical hysterectomy), or vaginal approach. Surgical approach, indication, and adjuvant therapy regimen were at the discretion of the treating institution. A total of 715 patients were entered into the study database. However, 69 patients were excluded, leaving 646 in the analysis. Endpoints were the 4.5-year disease-free survival rate (primary), 4.5-year overall survival rate (secondary), and recurrence rate (secondary). Kaplan-Meier methods were used to estimate disease-free survival and overall survival. A post hoc weighted analysis was performed, comparing the recurrence rates between surgical approaches, with open surgery being considered as standard and minimally invasive surgery as experimental., Results: Of 646 patients, 358 underwent open surgery, and 288 underwent minimally invasive surgery. The median (range) patient age was 32 (20-42) years for open surgery vs 31 (18-45) years for minimally invasive surgery (P=.11). Median (range) pathologic tumor size was 15 (0-31) mm for open surgery and 12 (0.8-40) mm for minimally invasive surgery (P=.33). The rates of pelvic nodal involvement were 5.3% (19 of 358 patients) for open surgery and 4.9% (14 of 288 patients) for minimally invasive surgery (P=.81). Median (range) follow-up time was 5.5 (0.20-16.70) years for open surgery and 3.1 years (0.02-11.10) years for minimally invasive surgery (P<.001). At 4.5 years, 17 of 358 patients (4.7%) with open surgery and 18 of 288 patients (6.2%) with minimally invasive surgery had recurrence (P=.40). The 4.5-year disease-free survival rates were 94.3% (95% confidence interval, 91.6-97.0) for open surgery and 91.5% (95% confidence interval, 87.6-95.6) for minimally invasive surgery (log-rank P=.37). Post hoc propensity score analysis of recurrence risk showed no difference between surgical approaches (P=.42). At 4.5 years, there were 6 disease-related deaths (open surgery, 3; minimally invasive surgery, 3) (log-rank P=.49). The 4.5-year overall survival rates were 99.2% (95% confidence interval, 97.6-99.7) for open surgery and 99.0% (95% confidence interval, 79.0-99.8) for minimally invasive surgery., Conclusion: The 4.5-year disease-free survival rates did not differ between open radical trachelectomy and minimally invasive radical trachelectomy. However, recurrence rates in each group were low. Ongoing prospective studies of conservative management of early-stage cervical cancer may help guide future management., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objective: Infective endocarditis (IE) may cause devastating complications with high morbidity and mortality rates. The aim of the present study was to study the demographic, cardiological, microbiologic, and dental profiles of patients with oral bacteria-related IE., Study Design: We present a retrospective study of patients with oral bacteria-related IE treated at Instituto do Coração, Hospital das Clínicas, Faculdade de Medicina, Universidade de Sao Paulo, Brazil, between January 2009 and December 2019., Results: Of the 100 patients included, 70% were male with a mean age of 45.4 years at diagnosis. The most affected sites were aortic and mitral valves, 60% in prosthetic heart valves, 34% in native valves, and 3% in pacemakers. The most common cause of valvular disease was rheumatic cardiopathy (51.9%), and the most frequent complications were valvular and perivalvular damage (26%). Streptococcus viridans was the most common species (96%), dental caries were present in 57% of the patients, 78% had tooth loss, 45% had apical periodontitis, and 77% were at high/moderate risk for periodontal disease., Conclusion: Oral bacteria-related IE among Brazilians was predominant in the prosthetic heart valves of young male adults previously affected by rheumatic cardiopathy. Streptococcus viridans was the main cause of IE, which was linked to patients with a poor oral health status., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objectives: Uncorrected refractive errors are the leading cause of visual impairment in children. In this cross-sectional retrospective study, we analyzed a social visual screening program for school children in São Paulo, Brazil, evaluated its impact on the prevention and treatment of children's visual disabilities, and assessed its epidemiological outcomes to outline suggestions for its improvement., Methods: First-grade children from public schools were submitted to prior visual screening by their teachers. Selected children were forwarded to the hospital's campaigns for a second screening by ophthalmologists and treatment if needed. Data were analyzed for age, sex, visual acuity, biomicroscopy, refractive errors, ocular movement disorders, amblyopia, number of donated spectacles, and number of children forwarded to specialized care., Results: A total of 1080 children were included with mean age of 6.24±0.45 years. Children with normal ophthalmological exam, 591 (54.7%; 95% confidence interval [CI]: 51.7%-57.7%) were dismissed and considered false-positives. Myopia, hyperopia, and astigmatism components were found in 164 (15.2%; CI: 13.1%-17.4%), 190 (17.6%; CI: 15.3%-20.0%), and 330 (30.5%; CI: 27.8%-33.4%) children, respectively. Amblyopia was diagnosed in 54 (5%; CI: 3.5%-6.4%) children, and 117 (10.8%; CI: 9.8%-12.8%) presented ocular movement disorders. A total of 420 glasses were donated., Conclusion: Epidemiological findings for amblyopia and refractive errors are consistent with those of similar studies. The expressive number of diagnoses performed and number of glasses donated to underprivileged children depict the importance of such projects. New guidelines to improve their cost-effectiveness, such as professional training and community sensitization, are imperative.

Objectives: A retrospective study was conducted to identify the prevalence of COVID-19 through serology and RT-PCR in children, adolescents and adults. A database of the COVID-19 Tracking Program in school children was used., Methods: The data comprised sociodemographic and clinical variables, results of serological tests (IgM and IgG), and real-time-polymerase chain reaction (RT-PCR) results of IgM-positive individuals. The statistical analysis was performed with a 5% significance level., Results: Among 423 children, 107 (25.3%) exhibited seroprevalence with IgG, IgM or IgG/IgM; among 854 adolescents, 250 (29.2%) had positive serology; and among 282 adults, 59 (20.9%) were positive. The frequency of positivity on RT-PCR for SARS-CoV-2 was 3.5%, 3.6% and 6.0% in children, adolescents and adults, respectively. Children had a lower incidence of symptoms than adolescents (p = 0.001) and adults (p = 0.003); the most frequent were fever, ageusia, anosmia, headache, dry cough, sore throat, muscle pain, runny nose, dyspnoea, and diarrhoea., Conclusions: The prevalence rate for all groups was 26.7% in serology and 4.04% in RT-PCR. Children had lower rates of IgM and fewer symptoms compared with adolescents and adults. The data suggest the potential for transmissibility in all age groups., (Copyright © 2021 The Authors.

Objective: To compare the socio-demographic, clinical, and diagnostic characteristics and treatment outcomes between extrapulmonary tuberculosis (EPTB) and pulmonary tuberculosis (PTB) in children and adolescents in Rio de Janeiro, a high TB-burdened Brazilian city., Methods: This retrospective study used data from patients with EPTB and PTB aged 0 - 18 years, notified on two national databases from 2014 to 2016., Results: Among the 1008 patients, 144 (14.2%) had EPTB. Patients with EPTB showed higher odds of hospital-based diagnosis (odds ratio (OR): 6.76 [95% confidence interval (95% CI): 4.62-9.90]; p < 0.001), no laboratory confirmation (OR: 4.9 2.14 [95% CI: 3.07 - 7.85]; p < 0.001), and being <14 years old (OR: 3.13 [95% CI: 2.18-4.49]) than those with PTB. A diagnosis without laboratory investigation was observed among 301/864 (34.8%) patients with PTB, 48/144 (33.3%) with EPTB, and among those aged under five years with EPTB (15/27 [55.6%]). TB deaths were more frequent in patients with EPTB (5/144 [3.5%]) than in those with PTB (4/864[0.5%]) (p = 0.001); 4/5 (80%) TB deaths were due to TB meningitis; 50% died within 14 days of diagnosis., Conclusions: EPTB remains a clinical diagnostic challenge that needs to be addressed to fully benefit from the higher sensitivity laboratory investigations., (Copyright © 2021 The Author(s).

Background: Acute basilar artery occlusion is a devastating life-threatening condition. Early recanalization is the therapeutic goal in patients with acute ischemic stroke. Despite the high rates of recanalization achieved with modern devices for basilar occlusions, many patients have had poor clinical outcomes. This study aimed to assess the predictors of good and poor outcomes among patients with basilar artery occlusion treated with thrombectomy., Methods: A consecutive registry of 80 patients was included in this retrospective study. The primary end point was to access variables associated with neurologic outcomes defined by a modified Rankin Scale (mRS) score of 0-2, symptomatic intracranial hemorrhage (sICH), and mortality at 3 months follow-up., Results: Recanalization was achieved in 86.2%, and the sICH rate was 8.7%. A good neurologic outcome (mRS score 0-2) was observed in 26.2% and a moderate outcome (mRS score 0-3) in 32.5% of patients. The mortality was 38.7% at 3 months follow-up., Conclusions: After thrombectomy for posterior circulation strokes, young patients, V4-proximal basilar occlusion, (high) baseline posterior circulation Alberta Stroke Program Early CT Score, and complete recanalization were independent predictors of good neurologic outcomes. Failure to recanalize was strongly related to sICH and mortality. In addition, diabetes, atrial fibrillation, and baseline National Institutes of Health Stroke Scale scores ≥10 had an independent association with mortality. This study contributes to the knowledge required to optimize recanalization treatments for posterior circulation strokes and may help to improve future clinical studies., (Copyright © 2020 Elsevier Inc.

Aim: To evaluate the clinical characteristics, diagnostic approach, and treatment outcomes of tuberculosis (TB) in children living in a high-burden metropolitan area., Methods: This was a retrospective study, based on a medical chart review, involving children under 15 years old treated for TB between 2007 and 2016, in four primary health units (PHU) and three reference centers (RC) in five cities of Rio de Janeiro metropolitan area. Factors associated with TB treatment setting, microbiological diagnosis, and treatment outcomes were evaluated., Results: A total of 544 children were enrolled; 71% were treated in PHU, 36% were under 5 years old, and 72% had pulmonary TB (PTB). The HIV prevalence was 10% (31/322). Fifty-three percent had at least one microbiological test for TB, 68% of them (196/287) had TB confirmed. Among 222 children with previous TB contact, information on LTBI was available for 78 (35%), and only 17% (13/78) were treated. Extrapulmonary TB (56% vs 32%), microbiologically confirmed TB (77% vs 60%), and HIV positivity (18.5% vs 4.0%) were significantly more frequent in RC. Treatment in RC (odds ratio (OR) 3.08, 95% confidence interval (CI) 1.74-5.44) and PTB (OR 2.47, 95% CI 1.34-4.56) were independently associated with a microbiological diagnosis of TB. The treatment success rate was 85%. In the logistic regression analysis, HIV-infected children had a 2.5-fold higher risk of an unfavorable outcome (OR 2.53, 95% CI 1.0-6.38; p = 0.05)., Conclusions: Opportunities for TB prevention and early TB treatment are missed due to suboptimal close contact screening. Microbiological diagnosis of TB and drug susceptibility testing in children should be made available through more sensitive and accessible tests., (Copyright © 2020 The Author(s).

Objective: To report initial experience from the use of extracorporeal membrane oxygenation (ECMO) in patients who received lung transplantation., Methods: Retrospective study of a single tertiary center in the Brazilian state of São Paulo, a national reference in lung transplantation, based on the prospective collection of data from electronic medical records. The period analyzed extended from January 2009 (beginning of the program) until December 2018., Results: A total of 75 lung transplants were performed, with ECMO used in 8 (10.7%) cases. Of the patients, 4 (50%) were female. The mean age was 46.4±14.3 years. The causes of the end-stage lung disease that led to transplantation were pulmonary arterial hypertension in 3 (37.5%) patients, bronchiectasis in 2 (25%) patients, pulmonary fibrosis in 2 (25%) patients, and pulmonary emphysema in 1 (12.5%) patient. In our series, 7 (87.5%) cases were sequential bilateral transplantations. Prioritization was necessary in 4 (50%) patients, and in 1 patient, ECMO was used as a bridge to transplantation. The ECMO route was central in 4 (50%), peripheral venovenous in 2 (25%) and peripheral venoarterial in 2 (25%) patients. The mean length of the intensive care unit (ICU) stay was 14±7.5 days and of the hospital stay was 34.1±34.2 days. The mean ECMO duration was 9.3±6.6 days with a 50% decannulation rate. Three patients were discharged (37.5%)., Conclusion: Lung transplantation requires complex treatment, and ECMO has allowed extending the indications for transplantation and provided adjuvant support in the clinical management of these patients.

Introduction: The purpose of this study was to analyze the features of lesions obtained from biopsies at the periapical area of teeth with a radiographic or clinical initial diagnosis of apical periodontitis., Methods: A retrospective study was conducted on biopsies obtained from 1953-2018 at 3 Brazilian oral and maxillofacial pathology centers. Cases of endodontic and nonendodontic periapical lesions (NPLs) with a clinical diagnosis of endodontic pathoses were retrieved. Data regarding patient age, sex, and anatomic location were obtained from patients' records. The frequency and percentage of cases with clinical diagnoses of a periapical cyst, periapical granuloma, or dentoalveolar abscess were recorded, and the final histopathologic diagnosis was documented., Results: Among 66,179 oral biopsies, 7246 (10.94%) were clinically diagnosed as periapical disease, 306 (4.22%) of which were histopathologically diagnosed as NPLs. The most frequent NPLs were odontogenic keratocysts (n = 107, 34.96%) followed by dentigerous cysts (n = 48, 15.68%). The mean age at diagnosis was 39.68 years with a range of 6-80 years. A total of 159 (51.96%) cases occurred in females and 147 (48.03%) in males (female to male ratio = 1.08:1). Most lesions (137, 44.77%) were located in the posterior mandible., Conclusions: A wide variety of histopathologic diagnoses, including benign odontogenic and nonodontogenic cystic and tumorous lesions, infectious diseases, and malignant neoplasms, was reported in the present survey. The features presented in this study were consistent with previous findings reported in the literature., (Copyright © 2020 American Association of Endodontists. Published by Elsevier Inc.

Objective: The aim of this study was to analyze the association between in-hospital complications and burn and trauma severity, inhalation injury, length of intensive care unit and hospital stay, and mortality in burned patients., Method: This observational and retrospective study included 68 burn patients hospitalized in a university hospital located in São Paulo, Brazil. The severity of the burn injury and trauma were measured by means of Abbreviated Injury Scale and the Injury Severity Score, respectively. Thecomplications were considered as a dependent variable. The statistical analysis for continuous variables was performed using the Student's t or the Mann-Whitney test and for categorical variables the Chi-square test, Fisher's Exact or Verisimilitude Ratio test, considering a significance level of 5%., Results: The majority (60.3%) of patients had complications, and among them, those with infections were the most frequent (70.7%). Burned patients with complications had higher burn injury severity, were hospitalized for longer and their mortality was higher. Cardiovascular complications were associated with severe burns and mortality; infectious ones with a larger length of hospitalization., Conclusion: Complications are frequent in patients with severe burns and inhalation injuries, increasing length of hospital stay and mortality. Burn studies measuring severity of thermal and inhalation injuries and other associated traumas allow to expand the analysis of burned patients., (Copyright © 2019 Elsevier Ltd and ISBI.

Firearms injuries have a legal and medico-legal importance, and are especially lethal when they reach the craniofacial regions of the victim. The present study aims to identify the characteristics of craniofacial lesions resulting from firearm projectiles, to register the most affected craniofacial regions by this type of injury and to verify the demographic profile of the victims. A retrospective study was carried out on the autopsy records produced in the first semester of 2015, in five Institutes of Legal Medicine in Porto Velho, situated in the cities of João Pessoa, Vitória, Porto Alegre and Brasília. Data extracted included sex, skin color and age of the victim, craniofacial region reached, shooting distance, shape and size of the injuries and manner of death (homicide, suicide or accident). Based on the 868 reports analyzed, it was possible to observe 1700 entrance lesions of firearm projectiles in craniofacial regions. Among cases of known manner of death, homicides were the most frequent (97.0%). It was observed a higher frequency of male victims (93.3%), mixed race (62.0%), between the ages of 12 and 29 years (59.4%). In all cases considered as suicide or accident there was only one entrance wound, but in 82.8% of the homicides there were multiple gunshot wounds. The craniofacial most affected regions were temporal (25.2%) and occipital (19.8%). The most common sites of projectiles exit were the temporal (25.3%) and parietal (16.1%). All cases of suicide were related to contact shot (69.2%) or close-range shot (30.8%), and among the homicides the distant range shots were more frequent (54.0%). The shape of entrance wounds was mostly circular (56.8%) and oval (31.3%), and among the exit injuries, the lesions were irregular (43.3%) and starry (24.1%). The entrance wounds showed smaller sizes than the exit lesions (p < 0.0001). The data obtained are useful for guiding research that takes into account craniofacial trauma caused by firearm projectiles, makes it possible to compare this data with those of other countries and can base investigative conclusions based on the analyzes discussed in the present work., (Copyright © 2019.

Purpose: We compared various clinical characteristics of pediatric-onset psychogenic nonepileptic seizures (PNES) between patients from five countries. The purpose of this study was to advance our understanding of pediatric-onset PNES cross-culturally., Methods: In this retrospective study, we compared consecutive patients with PNES with an age at onset of 16 years and younger from epilepsy monitoring units in Iran, Brazil, the USA, Canada, and Venezuela. Age, gender, age at seizure onset, seizure semiology, predisposing factors, and video-EEG recordings of all patients were extracted. Pearson Chi-Square, one-way ANOVA and Bonferroni correction tests were used for statistical analyses., Results: Two hundred twenty-nine patients were studied (83 from Iran, 50 from Brazil, 39 from Canada, 30 from the USA, and 27 from Venezuela). Mean age at the onset of seizures was 12.1 ± 3.2 years (range: 4-16 years). The sex ratio of the patients was 1.83: 1 (148 females and 81 males). Clinical characteristics of pediatric-onset PNES showed some significant differences among the nations. However, factors associated with pediatric-onset PNES in these five nations were similar., Conclusion: This study underscores how international cross-cultural studies can make important contributions to our understanding of PNES. Patients with pediatric-onset PNES from different countries were similar on many risk factors associated with PNES. This suggests universality in many features of PNES. However, intriguing differences were also noted with regard to seizure semiology, which might be the result of cultural factors., (Copyright © 2019 British Epilepsy Association.

Background: Brain tumors are frequent in clinical practice and associated with high morbidity and mortality. However, many diseases can present as tumefactive lesions and mimic neoplastic lesions. We aimed to determine the frequency of pseudotumoral central nervous system lesions referred to an oncology center and the frequency of the tumor mimickers., Methods: This was a retrospective study at the National Institute of Cancer, Rio de Janeiro, Brazil. Medical charts of patients admitted to the Neurosurgery and Pediatrics services from 2007 to 2011 were reviewed. Clinical and radiologic features of cases initially diagnosed with primary central nervous system tumors but received a final diagnosis of pseudotumoral disease were recorded., Results: Among 891 patients referred as primary brain tumors, 38 cases had pseudotumoral lesions (4.3%). Most were adults (63%), with mean age of 29.4 years, and women (60.5%). Most frequent symptoms were headache (28.9%), motor signs (23.7%), and seizures (15.8%). Mean time from initial symptoms to diagnosis was 12.2 months. Lesions were single in 84.2% of patients, had contrast enhancement in 45.6%, and surrounding edema in 17.4%. Twenty patients (52,6%) underwent biopsy. Systemic autoimmune diseases were the most frequent etiologies (28.9%), followed by idiopathic inflammatory demyelinating diseases, infections, and vascular abnormalities (15.8% each). Good outcome with no major deficits was observed in 60.5% cases., Conclusions: The frequency of pseudotumoral lesions in an oncology reference center was low. Young women were most affected, and lesions were associated more frequently with systemic autoimmune diseases. Prompt recognition is important to avoid unnecessary treatment, because most patients had a good outcome., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Objective: Evaluate the results obtained using a Dermal Regeneration Template (DRT) associated or not with the Negative Pressure Wound Therapy (NPWT) for skin cover in paediatric patients who were victims of burns., Method: Retrospective study of a cross-sectional study that evaluated the medical records of children submitted to the application of DRT, associated or not with NPWT, for the treatment of burned children admitted to the Joana de Gusmão Children's Hospital (JGCH) in Florianópolis, in the period from January 2011 to December 2016, totalling 45 patients., Results: The majority of the patients were pubescent (31.8%) males (56.8%), and the main aetiology of the burn was flammable substances (75%). In the group that used only DRT, the average take of DRT was 85% with an average time of maturity of 17.65days and the mean take rate of the skin graft was 85.2%. In the group that used DRT plus NPWT, the mean DRT take was 99.8%, with a mean maturation time of 16.68days and the mean of the skin graft take rate was 89.1%., Conclusion: NPWT associated with DRT offers a higher rate of success in the treatment of complex wounds caused by burns, promotes increased DRT take rate, reduces DRT maturation time and increases the take rate of the skin graft., (Copyright © 2018 Elsevier Ltd and ISBI.

Objectives: The use of illicit drugs is considered a risk factor for victimization by lethal violence and is frequently found in necropsies of homicide victims. This study aimed to evaluate the profile of these victims., Methods and Material: A cross-sectional retrospective study was performed on homicide victims in 2014 with a sample composed of all homicide cases in 2014 for which toxicology had been performed in an Official Forensic Laboratory (Minas Gerais- Brazil)., Results: 1382 homicide victims composed the sample. The group with a positive toxicology test (N = 943) presented higher proportions of men (p = 0.003), black/brown skin (p < 0.001), firearm history (p = 0.007) and a lower mean age (p < 0.001). In 72.2% of the positive tests, cocaine and benzoylecgonine were found; in 67.7%, THC and/or its metabolite was found; and in 43.1%, both illicit drugs were found., Conclusions: The role of illicit drugs in early death goes far beyond intoxication as they are directly associated with age, skin color and gender. Young black/mixed men have an increased risk of homicide. Our findings point to the importance of investing in social actions, public safety and efforts to reduce drug use in this at-risk population., (Copyright © 2019 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

This study aimed to verify the prevalence of IgG antibodies for Toxoplasma gondii, CMV, and EBV in tissue donors from different regions of Brazil between February 2016 and July 2017. In this retrospective study, 578 donors were evaluated from different regions of Brazil. The seroprevalence of T. gondii was 61.2%, CMV was 93%, and EBV was 98.3%. The seroprevalence increased with age, from 27.8% in donors younger than 18 years of age to 67.6% in those older than 60 years of age (p<0.05). The analysis of the seroprevalence of CMV and EBV showed similar percentages (>90%) among the different states, the interior and capital of Paraná state, sex, and age. The seroprevalence of CMV, EBV and TOXO is high in all groups and age in Brazilian donors of tissues., (Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Objectives: The aim of this study was to investigate the effects of primary healthcare decentralization on type 2 diabetes mellitus mortality and morbidity in different municipalities of a developing country., Study Design: This was a retrospective study based on a panel of annual data from 5560 Brazilian municipalities from 2000 to 2011., Methods: The investigation used the staggered municipal adoption of a federal health information program as a quasi-experiment to identify the treatment effects of health decentralization on diabetes indicators. Using Difference-in-Differences models and instrumental variables, we analyzed the effects of primary healthcare decentralization on diabetes rates (i.e. diabetes deaths and hospitalizations by the number of people with a diabetes diagnosis and by population)., Results: Evidence suggests improvements in universal access to primary health care and progress in the average health outcomes related to diabetes mortality (reduction of 30%) and hospitalization (reduction of 2.3%) due to decentralization. Effects are further pronounced in developed regions with higher incomes, while the poorest and less developed regions showed virtually no effect., Conclusions: These results demonstrate that there are particular preconditions for successful primary health decentralization, especially related to returns of scale (big health facilities are associated with low cost per treatment), lack of human and physical capital, and government coordination problems., (Copyright © 2018 The Royal Society for Public Health.

Objective: Schistosomiasis remains a public health problem. This was a descriptive and retrospective study of 42 patients with a severe form of schistosomiasis who were admitted to the outpatient clinic of the Faculdade de Medicina da Universidade de São Paulo, São Paulo, in São Paulo, Brazil., Methods: A data collection questionnaire was designed from the patient charts, and the following variables were evaluated: age, sex, place of birth, occupation, signs and symptoms of schistosomiasis, data from laboratory and imaging examinations, data regarding treatment outcomes, and the existence of comorbidities. Statistical analysis was carried out using Statistical Package for the Social Sciences 15.0 and Microsoft Excel 2003 software. The significance levels of the tests were fixed, accepting 5% type 1 error (α=0.05). Since this was a retrospective observational study, not all data were available for analysis., Results: The mean age of the patients was 48.24 years; 57.1% were male. Statistically significant associations were observed between splenomegaly and thrombocytopenia (p=0.004) and between splenomegaly and leukopenia (p=0.046); however, only 4.5% of the patients had esophageal hemorrhage. Some patients received a specific treatment; of those, 42% took praziquantel, and 35.4% took oxamniquine. Nonspecific drug therapy was given as follows: 65% received propranolol, 90% omeprazole, and 43.6% aluminum hydroxide. The other treatments were as follows: 92.9% of patients underwent endoscopic treatment, 85% received sclerotherapy, and 62.5% used elastic bandages., Conclusion: This preliminary study presents a multidisciplinary outpatient follow-up associated with endoscopic and drug treatments that may be effective at preventing bleeding.
