Introduction:To analyze the liver dysfunction and evolution of signs and symptoms in adult dengue patients during a two-month follow-up period. Methods: A prospective cohort study was conducted in Campos dos Goytacazes, Rio de Janeiro, Brazil, from January to July, 2008. The evolution of laboratory and clinical manifestations of 90 adult dengue patients was evaluated in five scheduled visits within a two-month follow-up period. Twenty controls were enrolled for the analysis of liver function. Patients with hepatitis B, hepatitis C, those known to be human immunodeficiency virus (HIV) seropositive and pregnant women were excluded from the study. Results: At the end of the second month following diagnosis, we observed that symptoms persisted in 33.3% (30/90) of dengue patients. We also observed that, 57.7% (15/26) of the symptoms persisted at the end of the second month. The most persistent symptoms were arthralgia, fatigue, weakness, adynamia, anorexia, taste alteration, and hair loss. Prior dengue virus (DENV) infection did not predispose patients to a longer duration of symptoms. Among hepatic functions, transaminases had the most remarkable elevation and in some cases remained elevated up to the second month after the disease onset. Alanine aminotransferase (ALT) levels overcame aspartate aminotransferase (AST) during the convalescent period. Male patients were more severely affected than females. Conclusions: Dengue fever may present a wide number of symptoms and elevated liver transaminases at the end of the second month.

Acute viral hepatitis A is a common systemic infection in children, especially in developing countries. Acute acalculous cholecystitis in the course of this infection is a rare and poorly reported event that needs to be diagnosed because of the possibility of complications, such as gangrene and perforation of the gallbladder wall. We present the case of a 16-year-old teenager with clinical and ultrasonographic findings of acalculous cholecystitis during an episode of hepatitis A virus infection, which took place December 2007 in Plantadores de Cana Hospital.

O trauma é uma importante causa de morbimortalidade em todo o mundo e, nesse contexto, o trauma de face é considerado uma das lesões mais devastadoras, devido às possíveis lesões encefálicas e às consequências emocionais relacionadas a deformidades estéticas. Os principais mecanismos de trauma envolvidos nessas lesões são acidentes automobilístico, seguido de agressões, queda de altura e acidentes esportivos. A tomografia computadorizada, amplamente utilizada no trauma, tornou-se o método de imagem de escolha na avaliação desses pacientes, sendo importante na identificação precisa das estruturas comprometidas, orientando a melhor abordagem terapêutica. As diversas formas de apresentação do trauma de face vêm se mostrando verdadeiros desafios na reconstrução funcional e estética desses pacientes, logo, a boa comunicação entre os diversos profissionais envolvidos no tratamento desses pacientes é essencial, especialmente entre radiologistas e cirurgiões. Os objetivos desta revisão são descrever os principais tipos de fraturas de face e discorrer sobre os achados de imagem mais relevantes no seu tratamento
