Abstract Ischemic strokes secondary to occlusion of large vessels have been described in patients with COVID-19. Also, venous thrombosis and pulmonary thromboembolism have been related to the disease. Vascular occlusion may be associated with a prothrombotic state due to COVID-19-related coagulopathy and endotheliopathy. Intracranial hemorrhagic lesions can additionally be seen in these patients. The causative mechanism of hemorrhage could be associated with anticoagulant therapy or factors such as coagulopathy and endotheliopathy. We report on cases of ischemic, thrombotic, and hemorrhagic complications in six patients diagnosed with SARS-CoV-2 infection. Chest computed tomography (CT) showed typical SARS-CoV-2 pneumonia findings in all the cases, which were all confirmed by either serology or reverse transcription polymerase chain reaction (RT-PCR) tests.

Abstract Background Lung ultrasound (LUS) can detect interstitial alveolar changes confined to the subpleural region, like those described in Covid-19. Objetive To evaluate how LUS findings correlate with chest computed tomography (CT) in patients admitted to the emergency department (ED) with suspicion of Covid-19. Methods Cross-sectional study of 20 patients (median age 43 years; interquartile range, 37–63 years; 50% male). All patients underwent LUS and chest CT on the day of ED admission. Each hemithorax was divided into 6 segments with similar landmarks, and equivalent scores (sc) of lesion severity were defined for both methods. The number of affected segments on LUS (LUSseg) was divided into tertiles (0-1, 2-5, and ≥6), and compared with number of affected segments on CT (CTseg), LUSsc, CTsc, and percentage of affected lung parenchyma through visual analysis (CTvis). ANOVA or Kruskal–Wallis test for continuous variables, chi-square test for categorical variables, and receiver operating characteristic (ROC) curve analysis to define optimal cutoff points were performed. P<0.05 was considered statistically significant. Results Median LUSsc, CTsc, CTseg, and CTvis were significantly different between groups. A clear separation between groups was demonstrated; patients with <2 affected segments on LUS were defined as low risk. The ROC curve showed good discriminative power to predict ≥6 affected segments on CT, with an area under the curve (AUC) of 0.97 and 0.98 for >7 LUSsc and >3 LUSseg, respectively. Conclusion LUS findings correlate with chest CT, and can help identify patients with normal lung or minor pulmonary involvement secondary to Covid-19.

INTRODUÇÃO: Agenesia vaginal relacionada à síndrome de Mayer-Rokitansky-Kuster-Hauser (MRKH) ocorre na proporção de 1 para cada 4000 ou 5000 nascimentos femininos, causando grande limitação à vida afetiva da paciente. O manejo da agenesia vaginal inclui acompanhamento psicológico e reconstrução vaginal. OBJETIVO: Mostrar a experiência do Serviço com a técnica do retalho neurovascular pudendo crural para reconstrução vaginal no tratamento de 8 pacientes com síndrome de Rokitansky. MÉTODO: Apresentam-se oito casos de síndrome de Rokitansky em que a reconstrução vaginal foi realizada pelo retalho neurovascular pudendo crural, chamado retalho de Cingapura. O período de acompanhamento pós-operatório variou de 6 meses e 3 anos. RESULTADOS: Uma neovagina funcional de, no mínimo, 10 cm de profundidade e 5 cm de diâmetro foi criada em todos os casos. Apesar da queixa de dor local de moderada intensidade no pós-operatório imediato, as pacientes apresentaram-se satisfeitas com os resultados. As relações sexuais foram liberadas no 40º dia de pós-operatório, sem relatos de sangramento ou dor. Três pacientes apresentaram crescimento de pêlo no intróito vaginal. CONCLUSÃO: A técnica do retalho de Cingapura permitiu a reconstrução vaginal sem a necessidade de dilatação pós-operatória, mantendo a inervação do períneo e com cicatrizes pouco perceptíveis.

BACKGROUND: Congenital vaginal agenesis, with a prevalence of 1 in 4000 or 5000 females, occurs mainly as a feature of the Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. The management of this patient includes psychological support and the creation of a neovagina. OBJECTIVE: To present and evaluate the pudendal thigh flap for the creation of a neovagina in eight young women with MRKH syndrome. METHODS: Eight young women with MRKH syndrome had a neovagina created by using the bilateral pudendal thigh fasciocutaneous flap procedure, Singapore flap. The patients' follow-up ranged between 6 months and 3 years. RESULTS: A functional vagina of at least 10cm in depth and 5cm in width was created in al cases. Although the patients reported moderated local pain after the procedure, they were satisfied with the results. In addition, normal sexual life was possible after 40 days and none of them reported bleeding or pain during sexual relation. Three patients presented hair in the vaginal lining. CONCLUSION: Bilateral fasciocutaneous pudendal thigh flap permits vaginal reconstruction with some advantages such as postoperative dilatation is not necessary, sensation is maintained and the resulting scars are inconspicuous.

INTRODUÇÃO: A ginecomastia é o aumento no tamanho da glândula mamária masculina, que pode ser fisiológico ou patológico, sendo condição passível de correção. OBJETIVO: Analisar o tratamento cirúrgico da ginecomastia, apontando suas principais complicações. MÉTODO: Duzentos e oitenta e quatro pacientes foram submetidos a cirurgia para correção da ginecomastia entre janeiro de 1998 e setembro de 2008, sendo 94,37% dos pacientes graus I e II e 5,63%, grau III. RESULTADOS: Em relação ao total de pacientes, 3,87% apresentaram seroma e 2,11%, hematoma (p<0,001). A análise dos pacientes graus I e II revela que 0,74% apresentaram cicatrizes hipertróficas nas incisões de lipoaspiração (p<0,001). Dentre os pacientes submetidos à técnica de Davidson, 18,75% apresentaram alargamento do complexo aréolo-mamilar (p=0,108) e foram submetidos a cirurgia para correção. CONCLUSÃO: As técnicas utilizadas para correção de ginecomastia se mostraram eficazes e seguras.

FUNDAMENTOS: O câncer de pele é o mais frequente tipo de câncer humano e mostra aumento de sua incidência. Em muitos casos, antes do surgimento do carcinoma, instala-se uma lesão precursora, ceratose actínica, podendo evoluir para carcinoma espinocelular. Estudos buscam determinar os parâmetros com significado prognóstico na predição daqueles tumores que terão comportamento mais agressivo. OBJETIVO: Avaliar a expressão dos marcadores de proliferação celular (PCNA, Ki-67) e apoptose (p53, Bcl-2), em portadores de carcinoma espinocelular e ceratose actínica. MÉTODO: Foram estudadas amostras de 30 pacientes: sendo dez portadores do carcinoma espinocelular; dez de ceratose actínica e dez indivíduos livres de lesões submetidos à blefaroplastia. RESULTADOS: A proteína p53 foi expressa em todos os casos estudados, embora apresentassem padrões quantitativos diferentes. O Bcl-2 foi expresso em baixa intensidade. Em seis casos de ceratose actínica, nas peles de blefaroplastia, e negativo nos casos de carcinoma espinocelular. O PCNA exibiu expressão intensa, em todas as amostras. O Ki-67 apresentou expressão variável, nos casos de carcinoma e de ceratose, e negativo na pele de pálpebra. CONCLUSÃO: A expressão do Ki-67 e a não-expressão de Bcl-2, no grupo CEC, indica intensificação da atividade proliferativa. Ao passo que, a maior expressão de p53 e Bcl-2, no grupo CA, sugere imortalização celular.

BACKGROUND: Skin cancer is the most frequent type of human cancer and has shown an increase in its incidence. In many cases, before the onset of the carcinoma, there might be a precursor lesion - actinic keratosis, which can develop into squamous cell carcinoma. Studies have been carried out in order to etermine the parameters that have prognostic significance in predicting those tumors which have more aggressive behavior. OBJECTIVE: To evaluate the expression of markers of cell proliferation (PCNA, Ki-67) and apoptosis (p53,Bcl-2) in patients with squamous cell carcinoma and actinic keratosis. METHOD: We studied samples from 30 patients, ten patients of squamous cell carcinoma, ten with actinic keratosis and ten lesion-free samples from blepharoplasty. RESULTS: p53 protein was expressed in all cases with different quantitative patterns. Bcl-2 was expressed at low intensity in six cases of actinic keratosis in the skin from blepharoplasty and negative in cases of squamous cell carcinoma. PCNA showed intense expression in all samples. Ki-67 showed variable expression in cases of keratosis and carcinoma and negative in the skin from the eyelid. CONCLUSION: The high expression of Ki-67 associated with low expression of Bcl-2 indicates proliferation in the carcinoma group. Thus, expression of p53 and Bcl-2 in patients with actinic keratosis indicates cell immortalization.
