Prevalence of oral and maxillofacial lesions in children and adolescents at a regional Brazilian oral pathology service: a retrospective study and the relevant literature review.

PURPOSE: This study assessed the prevalence of maxillofacial lesions in children, i.e., 0-9 years, and adolescents, i.e., 10-19 years, in a Brazilian Oral Pathology Service and compared results with available literature. METHODS: Clinical and histopathological records from January 2007 to August 2020 were analysed and a literature review investigating maxillofacial lesions in paediatric populations was also performed. RESULTS: Overall, "reactive salivary gland lesions" and "reactive connective tissue lesions" were the most prevalent group of soft tissue lesions, affecting children and adolescents equally. From these, mucocele and pyogenic granuloma were the most prevalent histological diagnoses, respectively, regardless of age. These findings were consistent with the 32 studies included. Considering intraosseous lesions, "odontogenic cysts" and "periapical inflammatory lesions" were the most prevalent groups, with no relevant differences between age groups, except for the odontogenic keratocyst, which was more prevalent in adolescents. Moreover, several odontogenic tumours, such as ameloblastic fibroma and odontogenic myxoma, were significantly more prevalent in children. CONCLUSION: Most maxillofacial lesions presented a similar prevalence between children and adolescents. Reactive salivary gland lesions and reactive connective tissue lesions were the prevailing diagnostic categories, regardless of age. Some odontogenic tumours and the odontogenic keratocyst showed significantly different frequencies across these age groups.

Sexual abuse victimisation and perpetration in a cohort of men living with HIV/AIDS who have sex with women from São Paulo, Brazil.

Sexual abuse leads to physical harm and devastating psychosocial consequences. It increases risk of HIV transmission and is associated with risky behaviour. Little is known about sexual abuse victimisation (SAV) and perpetration (SAP) among HIV-positive men who have sex with women (MSW). We investigated self-reported SAV and SAP among 242 Brazilian MSW selected at HIV care centres. Patients were questioned about sociodemographic data, mode of HIV acquisition, sexual practices, drug use and history of SAV or SAP. Prevalence of outcomes was estimated and risk factors for SAP investigated by logistic regression. Fifty-eight (24.1%) interviewees reported SAV. Of patients abused before 15 years of age, 64.3% reported events before the age of ten. Aggressors included relatives, friends and teachers. Among those victimised after 15 years old, 57.7% described events before 17 and 38.5% had acquainted aggressors. Fourteen (5.8%) interviewees reported SAP and most knew their victims. Sexual abuse perpetration was associated with lower schooling, marital status, illicit drug use and self-reported SAV. Sexual abuse was frequently reported by MSW from this cohort. Identifying predictors of violence and addressing SAV and SAP in comprehensive HIV care may help reduce violent behaviour, psychological distress and contribute to maximise benefits of preventive and care interventions.

Polipo anexial de la piel neonatal / Adnexal polyp of neonatal skin

El pólipo anexial de la piel neonatal (PAPN) es un tumor pequeño, localizado principalmente en la areola de los recién nacidos. Usualmente solitario, se desprende espontáneamente durante la primera semana de vida. Según nuestra casuística, se observa en el 3,6 porciento de los neonatos. Histológicamente se caracteriza por la presencia de elementos anexiales (folículos pilosos, glándulas ecrínas y vestigios de glándulas sebáceas)inmersos en un tejido colágeno laxo

Sexual orientation, use of drugs and risk perception among HIV-positive men in Sao Paulo, Brazil.

The aim of this cross-sectional study, carried out among 250 HIV-positive (HIV+) men who have sex with women, was to describe their risk perception before learning of their HIV+ status and their sexual and drug use behaviour. Of the 250 men, 62.0% were heterosexuals and 38.0% where bisexuals. They most often reported becoming infected through unprotected sex (24.5%) and injecting drug use (11.0%). They were usually tested because they became ill (42.2%). Condom use with women in all episodes of sexual intercourse before HIV+ diagnosis was reported by 22.6% of heterosexuals and 34.7% of bisexuals (P < 0.05). With respect to drug use, 58.0% reported the use of drugs at some period in their lifetime. A higher proportion of individuals who had used drugs perceived themselves at risk (P < 0.05). Findings showed that most HIV+ men who have sex with women, regardless of sexual orientation or injecting drug use, did not use condoms and did not perceive themselves at risk before learning of their HIV+ status, and only undergo testing due to illness. The implications for heterosexual transmission of HIV are discussed.
