Characterization of male sexual assault in the state of São Paulo, Brazil: an epidemiological study from 2014 to 2017.

Sexual violence is a pervasive global issue that affects individuals of all genders. However, the experiences of male survivors have often been marginalized and inadequately represented. Male rape, which encompasses several forms of sexual violence against men, remains a sensitive and under-discussed topic in academic literature and public discourse. This study presents a descriptive cross-sectional analysis based on data collected from the Legal Medicine Institute (IML-São Paulo, Brazil) between 2014 and 2017. The analysis includes 7386 reports of sexological examinations performed on male victims of alleged rape. The analysis reveals that a significant majority of rape reports involved victims under the age of 12 or 14, which is considered vulnerable rape by the Brazilian legislation. Regarding the examination of reported cases of abuse against men, it was observed that only the minority of these cases exhibited visible injuries consistent with rape or tested positive for the presence of spermatozoa in the perianal region. Since the absence of visible injuries or spermatozoa does not negate the possibility of rape, this work highlights the challenges in obtaining conclusive evidence, necessitating a comprehensive approach to investigate and prosecute these crimes, creating a more inclusive and supportive environment for all survivors of rape, irrespective of their gender.

Suicide victims and alcohol-related consumption in Brazil: An observational study and a narrative review of the literature.

Deaths due to external causes, mainly suicide, are a severe public health problem in Brazil. Evidence shows that the tendency to impulsive behavior is exacerbated after alcohol consumption. The relationship between alcohol and suicide is poorly described in the medical literature. The study aims to analyze the relationship between victims' blood alcohol levels and suicides in some municipalities in Greater São Paulo, Brazil. We reviewed the data from the medical records of 805 necropsies performed at the Medical Legal Institute of Sao Paulo in Franco da Rocha, Brazil, from 2001 to 2017. The manner of death was established based on the result of police inquiry. Deaths due to suicide (n=41) were selected for the study. Descriptive statistics and Student t-test was applied when appropriate. The variables studied were sex, age, suicide mechanism, and blood alcohol level (BAC). In all cases we could not determine how much time the deceased consumed alcohol before suicide. Of the individuals analyzed, 85.36% were male, and 14.64% were female. The most prevalent age range for males was between 18 and 23 (19.5%). For females, it was between 12 and 23 years (33.2%). Most suicides (48.78%) were due to hanging, followed by self-poisoning (22.08%) and firearms (17.1%). 38 victims (92.68%) presented a positive BAC, over 0.3 mg/dl. The higher levels were in the group of suicide by hanging (2.3 mg/ml). Thus, alcohol intoxication is common among suicide victims, and it can contribute to the fatal outcome as a risk factor. Further studies are necessary for a better comprehension of the effect of alcohol on suicide victims.

Male rape in Brazil: A descriptive analysis from 2010 to 2022.

Male rape is a relatively under-discussed topic in scientific literature, despite its significant relevance and prevalence worldwide, including in Brazil. To inform public health and safety policies, this study aimed to analyze cases of male rape using data from SINAN, the Information System for Notifiable Diseases, a division of the Brazilian Ministry of Health, for the years 2010-2022. Our findings reveal a 469 % increase in male rape cases in the country over the study period, with a predominance of cases in the state of São Paulo. Also, a higher prevalence of cases was observed among individuals aged 5-9 years. Furthermore, we identified a correlation between the occurrence of rape and certain factors, including individuals with less than 4 years of formal education if they were over the age of 50, and those who had a history of being sexually abused between the ages of 5 and 14. Additionally, this study reinforces the prevalence of rape cases occurring within domestic environments and perpetrated by individuals closely related to the victims. This study contributes to filling the gap in research on male rape in Brazil, laying the foundation for the development of strategies to prevent and combat rape in the country.

Medical errors, medical negligence and defensive medicine: A narrative review.

Error in medicine and medical liability has a long history dating back to Antiquity. During the 19th Century, most lawsuits related to errors in treating surgical problems were settled. However, in the first half of the 20th Century, lawsuits claimed that mistakes were related to the doctor's action: the doctor made something wrong (errors of commission). In Brazil, medical error is defined as inappropriate conduct, including negligence and recklessness, that causes harm to the patient. The physician's fear of being suited is the reason for some practice named defensive Medicine (D.M.), defined as ordering unnecessary tests and procedures or avoiding treatments for patients considered at high-risk. Thus, this narrative review aims to analyze and describe the relationship between medical errors, medical negligence, and the practice of D.M. So, the authors propose procedures and attitudes to avoid medical errors and the approach of D.M.: a national focus to create leadership and research tools to enhance the knowledge base about patient safety; a reporting system that would help to identify and learn from errors; the use of a computer-based protocol reminder; some technological devices to help the medical practice (electronic prescribing and information technology systems); creating risk management programs in hospitals. Therefore, the authors conclude that the most critical attitude to avoid medical liability is a good and ethical medical practice with the proper use of technology, based on knowledge of scientific evidence and ethical principles of medicine - for the benefit of patients.

Physical evidence of rape against children and adolescents in Brazil: Analysis of 13,870 reports of sexual assault in 2017.

Introduction: The medical literature reports child and adolescent maltreatment since the 8th century. Unfortunately, even today, the incomplete knowledge of this event persists. Several forms of violence are applied to children and adolescents, mainly sexual violence including rape and sexual assault. Forensic medical examinations routinely include the genital area, anus, and the body of the victims for signs of a recent or old injury. The main goal of this study is to show the results of physical and sexual examinations regarding confirmation of rape in children and adolescents, based on the medicolegal reports. Methods: We made a descriptive cross-sectional study conducted by collecting data from Medicolegal Institute (IML-São Paulo, Brazil) in 2017. We examined 13,870 reports of sexological examinations of victims of the alleged rape. The variables analyzed were age; sex; physical examination; sexological examination; and direct search for sperm in the vaginal, anal, or oral cavity. We selected 11,725 reports from victims under 18 years. Results: As for the medical-legal findings, only 1735 reports (14.8%) confirmed sexual abuse. The most affected ages were between 3 and 5 years in the male group and 11 to 14 years in the female group. The most frequent injuries were bruises and abrasions, fissures in the anal region. In 96.2% of the examined males and 85.8% of the females under 14 years old, the examination was inconclusive, and somebody cannot prove the alleged rape. Only 1735 reports (113 from men and 1622 from women) concluded beyond any doubt the alleged rape (14.8%). The search for sperm was positive in only 1582 cases (13.5%). Conclusion: This study shows that the results of the medicolegal examinations were quite limited in recording evidence. Sexual violence against children and adolescents reaches mostly females under 13 years of age. Besides, it is a complicated crime to prove, as 85.8% of female examinations and 96.2% of male exams revealed: "no supporting elements" or "undetermined" to characterize the felony. Therefore, to prevent it, the communication of the alleged rape must be made as quickly as possible.

Three different mechanisms of death: an unusual form of a child murder by asphyxia.

We report a very unusual case of murder of a 4-year-old male white child who died of asphyxiation. Asphyxia occurred due to 3 factors: manual strangulation, hyperextension of the neck, and atlantoaxial subluxation. The offenses were carried out by a single assailant (the stepfather of the child) who strangled the child with his right hand, using his left hand to pull the hair of the child, forcing the head back and causing hyperextension of the neck, thereby dislocating the first and second cervical vertebrae.

Rhinosinusitis in HIV-infected children undergoing antiretroviral therapy.

UNLABELLED: The association of protease inhibitors (PI) to antiretroviral therapy has generated sensible changes in morbidity and mortality of HIV-infected patients. AIM: Aims at evaluating the impact of this association on the prevalence of rhinosinusitis (RS) and CD4+ lymphocyte count in HIV-infected children. METHODS: Retrospective cross-sectional study of the medical charts of 471 HIV-infected children. In 1996, protease inhibitors were approved for use as an association drug in antiretroviral therapy. Children were divided into two groups: one which did not receive PI and another which received PI after 1996. The prevalence of RS and CD4+ lymphocyte counts were compared between these groups. RESULTS: 14.4% of HIV-infected children had RS. Chronic RS was more prevalent the its acute counterpart. Children under 6 years old who were taking protease inhibitors presented with a significant higher prevalence of acute RS. The association of PI with the antiretroviral regimen was associated to higher mean CD4+ lymphocyte count and lower prevalence of chronic RS. CONCLUSIONS: The use of protease inhibitors was associated to higher mean CD4+ lymphocyte count. Children under 6 years of age in antiretroviral therapy associated with PI presented a lower likelihood of developing chronic RS.

Oral lesions as predictors of highly active antiretroviral therapy failure in Brazilian HIV-infected children.

OBJECTIVES: Evaluate the accuracy of HIV-related oral lesions to predict immune and virologic failure on HIV-infected children in use of highly active antiretroviral therapy (HAART). STUDY DESIGN: Data for this cross-sectional analysis come from a longitudinal study being conducted through the HIV-AIDS Outpatient Unit, ENT Division, Hospital das Clinicas, Sao Paulo University Medical School. The study began in January 1990 and is still ongoing. The cut-off point for analyses purposes was December 2004. Subjects were 471 HIV-infected consecutive children attending the outpatient unit during this period, who enrolled regardless of medical or immunological status. The children have undertaken oral cavity examination, serum CD4(+) T-lymphocyte count, and, 271 of them, viral load measurement. Sensitivity, specificity, positive predictive value, negative predictive value and relative risk were calculated. RESULTS: Oral lesions had moderate sensitivity, high specificity and positive predictive value to predict immune failure. It had low sensitivity and positive predictive value, and high specificity to predict virologic failure. DISCUSSION AND CONCLUSIONS: Oral manifestations of HIV can be important markers for immune suppression and for virologic failure, in Brazilian children undergoing HAART.

The role of immunofluorescence in the physiopathology and differential diagnosis of recurrent aphthous stomatitis.

UNLABELLED: Recurrent aphthous stomatitis (RAS) is a disease characterized by the periodic appearance of aphthous lesions on the oral mucosa, of which etiology and physiopathology are not well explained. Recent studies with direct immunofluorescence show controversial results. Some reveal that the basic disorder is associated with humoral immunity, while others point to changes in cellular immunity. Atypical forms of aphthous stomatitis may have its differential diagnosis carried out with vesicobullous diseases, such as pemphigus vulgaris. AIM: Check the presence of immunocomplexes in the mucosa of patients with aphthous stomatitis and the usefulness of the differential diagnosis method with bullous skin diseases. MATERIALS AND METHODS: 23 patients with aphthous stomatitis were prospectively included in the study. There were all submitted to mucosa biopsy under local anesthesia for the removal of two fragments. One of these was sent to histology and, the other to direct immunofluorescence. RESULTS: The 23 samples from the histology exam revealed an ulcerated inflammatory process. The samples referred to immunofluorescence resulted negative and only one showed the presence of complement in the basal membrane. CONCLUSION: Based on our results, we conclude that the patients with RAS do not show deposits of immunocomplexes in their oral cavity mucosa and immunofluorescence is useful in the differential diagnosis between this disease and bullous skin diseases.

HLA-C*17, DQB1*03:01, DQA1*01:03 and DQA1*05:05 Alleles Associated to Bullous Pemphigoid in Brazilian Population.

BACKGROUND: Bullous pemphigoid (BP) is an autoimmune disease with bullous vesicles and an incidence of 0.2 to 1.4 per 100,000 inhabitants. Many studies have been published demonstrating the association of pemphigoid with HLA class II system alleles in different populations, however there are no data on the BP, one of the most heterogeneous in the world. OBJECTIVE: To typify HLA alleles in Brazilians with Bullous pemphigoid. METHODS: The study group included 17 Brazilian patients with a confirmed diagnosis of BP from a hospital in Sao Paulo city, southeast Brazil. DNA was extracted from peripheral blood using Qiagen kits and HLA A, B, C, DR and DQ typing was performed using polymerase chain reaction. The control group was composed of a database of 297 deceased donors from the city of Sao Paulo. The statistical significance level was adjusted using the Bonferroni correction depending on the phenotypic frequencies evaluated for HLA class I (A, B and C) and class II (DRB1, DQB1 and DQA1). RESULTS: Our findings show that alleles HLA C*17, DQB1*03:01, DQA1*01:03 and DQA1*05:05 are associated with the onset of the disease in the Brazilian population, with relative risks of 8.31 (2.46 to 28.16), 3.76 (1.81 to 7.79), 3.57 (1.53 to 8.33), and 4.02 (1.87 to 8.64), respectively (p<0.005). CONCLUSION: Our data indicate that Brazilian patients with BP present the same genetic predisposition linked to HLA-DQB1*03:01 previously reported in Caucasian and Iranian individuals and our study introduces three new alleles (C*17, DQA1*01:03 and DQA1*05:05) involved in the pathophysiology of BP.

The authors state that a good and ethical medical practice can avoid medical liability.

Alcohol use among fatally injured victims in São Paulo, Brazil: bridging the gap between research and health services in developing countries.

BACKGROUND AND AIMS: Most studies reporting alcohol use among fatally injured victims are subject to bias, particularly those related to sample selection and to absence of injury context data. We developed a research method to estimate the prevalence of alcohol consumption and test correlates of alcohol use prior to fatal injuries. DESIGN, SETTING AND PARTICIPANTS: Cross-sectional study based on a probability sample of fatally injured adult victims (n = 365) autopsied in São Paulo, Brazil. Victims were sampled within systematically selected 8-hour sampling blocks, generating a representative sample of fatal injuries occurring during all hours of the day for each day of the week between June 2014 and December 2015. MEASUREMENTS: The presence of alcohol and blood alcohol concentration (BAC) were the primary outcomes evaluated according to victims' socio-demographic, injury context data (type, day, time and injury place) and criminal history characteristics. FINDINGS: Alcohol was detected in 30.1% [95% confidence interval (CI) = 25.6-35.1)] of the victims, with a mean blood alcohol level (BAC) level of 0.11% w/v (95% CI = 0.09-0.13) among alcohol-positive cases. Black and mixed race victims presented a higher mean BAC than white victims (P = 0.03). Fewer than one in every six suicides tested positive for alcohol, while almost half of traffic-related casualties were alcohol-positive. Having suffered traffic-related injuries, particularly those involving vehicle crashes, and injuries occurring during weekends and at night were associated significantly with alcohol use before injury (P < 0.05). CONCLUSIONS: Nearly one-third of fatal injuries in São Paulo between June 2014 and December 2015 were alcohol-related, with traffic accidents showing a greater association with alcohol use than other injuries. The sampling methodology tested here, including the possibility of adding injury context data to improve population-based estimates of alcohol use before fatal injury, appears to be a reliable and lower-cost strategy for avoiding biases common in death investigations.

Confidencialidade em medicina ocupacional: protegendo informações / Confidentiality in occupational medicine: protecting information / Confidencialidad en medicina del trabajo: protección de información

Resumo A confidencialidade é elemento central da relação médico-paciente e está associada à boa qualidade do atendimento. Contudo, pode ser rompida em conformidade com as normas éticas e legais estabelecidas no país. Este estudo objetiva mostrar os principais aspectos da confidencialidade em medicina ocupacional. Para isso, realizou-se revisão narrativa de literatura sobre o tema, utilizando bases de dados de livre acesso e embasando-se nos códigos de ética médica. A atuação do médico do trabalho envolve o trabalhador, outros profissionais não médicos e o empregador, situação capaz de desencadear conflitos, requerendo que o médico conheça suas obrigações e limites ético-legais. A proteção da confidencialidade respeita os direitos humanos, mas dilemas podem surgir, não bastando obedecer aos ditames éticos, mas sendo necessário essencialmente seguir as normas legais. Este estudo busca mostrar os principais aspectos éticos e legais atualizados referentes à saúde ocupacional.

Abstract Confidentiality is a central element of the physician-patient relationship and is associated with good quality of care. However, it may be broken in accordance with the ethical and legal standards established in the country. This study aims to show the main aspects of confidentiality in occupational medicine. For this, a narrative review of the literature on the subject was carried out, using free access databases and based on the codes of medical ethics. The occupational physician's performance involves the worker, other non-medical professionals and the employer, a situation that may trigger conflicts, requiring physicians to know their obligations and ethical-legal limits. The protection of confidentiality respects human rights, but dilemmas may arise, not only to obey ethical precepts, but to follow legal norms. This study seeks to show the main and updated ethical and legal aspects regarding occupational health.

Resumen La confidencialidad es clave en la relación médico-paciente y está asociada a buena calidad de la atención. Sin embargo, está sujeta a una quiebra de conformidad a lo establecido en las normas éticas y legales en el país. Este estudio pretende mostrar los principales aspectos de confidencialidad en la medicina del trabajo. Para ello, se realizó una revisión narrativa de la literatura en las bases de datos de acceso abierto basándose en códigos de ética médica. El actuar del médico del trabajo involucra al trabajador, a profesionales no médicos y al empleador, lo que puede desencadenar conflictos requiriendo que el médico conozca sus obligaciones y límites ético-legales. La protección de la confidencialidad respeta los derechos humanos, pero pueden surgir dilemas y no solo bastará atenerse a los dictámenes éticos, sino seguir fundamentalmente las normas legales. Los resultados mostraron los principales aspectos éticos y legales actualizados relacionados con la salud laboral.

HAART impact on prevalence of chronic otitis media in Brazilian HIV-infected children.

UNLABELLED: The advent of new antiretroviral drugs such as protease inhibitors has generated sensible changes in morbity and mortality in HIV-infected patients. OBJECTIVES: To evaluate the impact of Highly Active Antiretroviral Therapy (HAART) on the prevalence of chronic otitis media in HIV-infected pediatric population. METHODS: We analyzed medical charts of 471 children aged zero to 12 years and 11 months with HIV infection from an Ambulatory of ENT and AIDS. Children were divided according to the age: 0 to 5 years and 11 months and 6 to 12 years and 11 months and classified as having chronic otitis media based on history, physical examination, audiologic and tympanometric data. Prevalence of chronic otitis media, as well as CD4+ lymphocyte count were compared between groups in use of HAART and the group without HAART. RESULTS: Out of 459 children, 65 (14.2%) had chronic otitis media. We observed that in children aged 0 to 5 years and 11 months who were taking HAART there was significant lower prevalence of chronic otitis media (p=0.02). The use of HAART was associated to higher mean CD4+ lymphocyte count (p<0.001). CONCLUSION: The use of HAART was associated to reduction in prevalence of chronic otitis media in HIV infected children, probably due to increase in mean CD4+ lymphocyte count.

Infantile recurrent parotitis: follow up study of five cases and literature review.

UNLABELLED: Recurrent parotitis (RP) is defined as recurrent parotid inflammation, generally associated with non-obstructive sialectasis of the parotid gland. It is a rare condition, and its etiology remains an enigma. AIM: The purposes of the present study were (1) to relate the follow up of five RP cases; (2) to examine the role of sialography and ultrasound in diagnosis and follow up; and (3) to make a literature review. STUDY DESIGN: Series review. MATERIAL AND METHOD: We reviewed all recurrent parotitis cases from the files of the Otolaryngology Division at University of Sao Paulo, Brazil. The criteria for inclusion were at least two years of evolution and more than one year and a half follow-up in our service. We included five children in the study. Sialography was performed in the first evaluation and sonography was executed annually. Recurrent parotitis showed male predominance, and affected mainly children between the ages of 3 and 6. Frequency of crisis improved with time in all cases. Sialography showed sialectasis aspect in the affected glands and sonographic exams demonstrated hypoechoic and heterogeneous internal echoes. One case showed regression of ultrasound changes after clinical improvement.

AIDS and Recurrent Aphthous Stomatitis.

UNLABELLED: The immunodeficiency state in HIV infected patients has been the cause of severe episodes of Recurrent Aphthous Stomatitis (RAS). AIM: Our study aims to establish correlation between the manifestations of RAS and the immunosuppression state caused by HIV infection, through counting of CD4+ cells, CD8+ cells, CD4+:CD8+ cells ratio and viral load. STUDY DESIGN: Series study. MATERIAL AND METHOD: Ninety-four HIV infected patients (25 women and 69 men) with RAS were evaluated in the ENT Department of the University of Sao Paulo-Medical School from January 1998 to December 2003. The age ranged between 19 and 63 years (mean = 35.3 years). The patients were divided in two groups: AIDS group and HIV infected group. RESULTS: The patients with AIDS and HIV infection presented, respectively, eight ulcers and two ulcers by outbreaks. Similarly, patients with major RAS presented smaller counting of cells CD8+, CD4+ and CD4+/CD8+ cells, and higher mean value of viral load than the patients with herpetiform and minor RAS. Between patients with minor and herpetiform RAS there were no statistical differences. CONCLUSIONS: The emergence of the lesions, mainly in major RAS, is directly related to the immunological state of the HIV infected patient. These patients frequently present nutritional deficits and worsening in life style. Thus, diagnosis and treatment of RAS is a challenge that should not be neglected.

Chronic rhinosinusitis in HIV-infected patients: radiological and clinical evaluation.

UNLABELLED: The advent of protease inhibitors, which enhances the survival rate of HIV-infected individuals, leads patients to search for otorhinolaryngologists, as 40-70% of them may present some sort of otorhinolaryngological disorder. AIM: We aimed at comparing the CT scan findings and the nasosinusal complaints of HIV-infected and AIDS patients with clinical diagnosis of chronic rhinosinusitis. The literature on the subject is revised and discussed. STUDY DESIGN: Clinical prospective with transversal cohort. MATERIAL AND METHODS: Prospectively, 39 patients with chronic rhinosinusitis, in use of antiretroviral therapy, were included in the present study and divided into two groups: patients with diagnosis of AIDS (group I) and those infected by HIV (group II). Clinical and laboratorial assessments, with CD4+ cell count and CT evaluation, were performed and compared among groups I and II. RESULTS: Group I and II presented mean CD4+ cell count of 118 cells/10-9l and 377 cells/10-9l, respectively. Comparison of the tomographic findings by the Lund-Mackay staging system presented a score of 12 for group I and 5.63 (pd" 0.001) for group II. Fever and postnasal discharge were more prevalent in group I (pd" 0.001). CONCLUSIONS: In our Service, prevalence of chronic rhinosinusitis in HIV-infected patients was 12%. AIDS patients had a higher incidence of fever and postnasal discharge than those of group II. Moreover, extensive radiological findings were prevalent in patients with AIDS (group I) than in HIV-infected individuals (group II).
