Meningeal Carcinomatosis for Prostate Adenocarcinoma Mimicking Chronic SubduralHematoma: Case Report and Literature Review

Introduction Cerebral metastases are the most common cancer of the central nervous system (CNS). Meningeal infiltration by neoplasms that did not originate in the CNS is a rare fact that is present in 0.02% of the autopsies. Epidemiologically, the radiological presentation mimicking a subdural hematoma is even more uncommon. We report a case of meningeal carcinomatosis by an adenocarcinoma of the prostate mimicking a chronic subdural hematoma. Case Report A 60-year-old male patient was diagnosed with prostate cancer in 2011. He underwent radical resection of the prostate, as well as adjuvant hormonal therapy and chemotherapy. Five years later, the patient presented peripheral facial paralysis that evolved with vomiting and mental confusion. Tomography and magnetic resonance imaging scans confirmed the subdural collection. At surgery, the dura was infiltrated by friable material of difficult hemostasis. The anatomicopathological examination showed atypical epithelial cells. The immunohistochemistry was positive for prostate-specific antigen (PSA) and other keymarkers, and it was conclusive for meningeal carcinomatosis by a prostate adenocarcinoma.

"Mão na cabeça!": abordagem policial, racismo e violência estrutural entre jovens negros de três capitais do Nordeste / "Hands up!": Police stop-and-frisk, racism and structural violence among black youth from three capitals in the Brazilian Northeast

Resumo A intersecção entre raça, classe social, pertencimento territorial e perfil etário tem sido determinante na produção dos critérios de suspeição na prática policial brasileira. Jovens negros, pobres e moradores de favelas configuram o público alvo das abordagens policiais. Propõe-se, neste artigo, apresentar os resultados do estudo que explorou experiências e percepções de jovens negros(as) pertencentes a bairros socialmente vulneráveis e/ou com altos índices de violência nas cidades de Salvador, Recife e Fortaleza, relacionadas com abordagem policial. A pesquisa foi guiada pelas seguintes questões: como jovens negros vivenciam e (re)significam a relação com a polícia e, mais especificamente, a abordagem policial? Em que medida marcadores de pertencimento social, tais como perfil racial, classe e território, influenciam no processo de abordagem? Foi realizado um estudo qualitativo através de grupos focais, rodas de conversa e entrevistas semiestruturadas com jovens negro(as) de 15 a 29 anos, moradores de bairros periféricos das três capitais referidas. Os dados revelaram que a segregação racial e o racismo, presentes na estrutura e dinâmicas relacionais da sociedade brasileira, assim como sua negação e/ou certa naturalização, influenciam a "tomada de decisão" e o modo de atuar da polícia frente à juventude negra nas três capitais investigadas.

Abstract The intersection between race, social class, territorial belonging and age profile has been decisive in producing the criteria of suspicion employed by Brazilian police. Young blacks who are poor and inhabit favelas are a prime target for police control actions such as the stop-and-frisk. This article presents the results of a study exploring the experiences and perceptions of police approach as voiced by young blacks from neighborhoods that are socially vulnerable and/or have high levels of violence. The study was carried out in the cities of Salvador, Recife and Fortaleza. The research was guided by the following questions: how do young blacks experience and (re)signify their relationship with the police and, more specifically, the police approach? To what extent do social belonging markers, such as racial profile, class and territory, influence the stop-and-frisk process? A qualitative study was carried out by means of focus groups, conversation circles and semi-structured interviews with black youths aged 15 to 29 living in peripheral neighborhoods of the three aforementioned capitals. The data revealed that racial segregation and racism present in the structure and relational dynamics of Brazilian society - as well as its denial and/or naturalization - influence the police's "decision-making" and way of dealing with black youth in the three investigated capitals.

Testicular schistosomiasis as differential diagnosis for testicular nodules: a case report

Despite its infrequent occurrence, testicular schistosomiasis forming pseudo-tumors can be considered in the differential diagnosis of testicular tumors, especially in areas where the parasitic disease is endemic. In this report, we present a case of testicular schistosomiasis caused by Schistosoma mansoni and mimicking a testicular neoplasm. We describe the patterns of a testicular nodule on ultrasonography and magnetic resonance images in a 46-year-old man. The nodule was removed after a pre-operative diagnosis of a non-malignant lesion. Histology demonstrated granulomas with epithelioid macrophages and eosinophils around S. mansoni eggs within a fibrous tissue that formed a nodular structure.
