Labrea-like hepatitis in Vitoria, Espirito Santo state, Brazil: report of a case

A case of fulminat hepatitis with microvesicular steatosis resembling Labrea 's fever, diagnosed in Vitoria (ES) is reported. The 16 year old bcy presented with severe epistaxis, agitation, jaundice and hemorrhagic vomiting and died two days after admission to the emergency unit of the Vnivesity Hospital. The disease started five days before with fever, myalgias, dark urine and jaundice andprogressed withpsychic agitation, torpor and coma. The liver andspleen were notpalpable. HBsAg was negative in the serum. The autopsy showed acute hepatitis with tylic necrosis confluent in the midizonal and periportal areas with massive microvesicular steatosis in the remaining hepatocytes. Mononuclear cellspredominated in the exudate. The reticulum showed condensation in the necrotic areas without typical bands of collapse. The portal tracts were edematous with mononuclear infiltration and mild bile duct proliferation. Absence of cholestasis. Exceptfor the confluent midzonalandperiportal necrosis this case showed several clinical and morphological aspects of the Labreafever describedfrom the East Amazon, demonstrating that the anatomical picture of this disease probabty is not in related to afactor peculiar to the Amazon region.

A clinico-pathological study of 163 untreated cases of chronic hepatitis C

We performed a clinico-pathological study of 163 untreated cases of chronic hepatitis C. Eighty five percent of the patients were clinically asymptomatic and their physical examinations sbowed unremarkable or minimal changes at the time of the liver biopsy Liver function tests tended to present slight abnormalities, involving mild elevations of the activity of the aminotransferases and gamma-glutamil transferase levels. In spite of these mild abnormalities advanced chronic liver disease ivas histologically detected in eighty nine percent of the patients, mainly showing chronic active hepatitis. The most characteristic histological finding ivas an interlobular bile duct damage which correlated with the presence of tymphoid aggregates in the portal tracts and with the development of fibrosis.

Sobre a reversão da fibrose hepática esquistossomótica após terapêutica específica. Estudo histológico

Biópsias cirúrgicas de fígado de portadores da forma hepatesplênica compensada da esquistossomose mansônica, previamente tratados com oxaminiquine (Mansil) e submetidos, posteriormente, à anastomose esplenorrenal, foram estudadas através de algumas técnicas histológicas e imunohistoquímicas. Embora a pesquisa de vermes adultos, de ovos e/ou de granulomas fosse negativa, em todos os espécimes examinados, a fibrose portal estava presente.

A livraria de D. Teodósio (1510?-1563), Duque de Bragança

O presente ensaio procura definir a livraria de D. Teodósio, 5.º duque de Bragança, em função de dois critérios principais: o da sua inserção no inventário geral do património do duque através do inventário post-mortem, onde os livros se incluem, aferindo da sua importância quantitativa enquanto objecto; em segundo lugar, procuraremos avaliar a sua dimensão através de uma perspectiva comparada com outras livrarias aristocráticas e régias suas contemporâneas. Podemos afirmar, com segurança, que com a absoluta excepção da livraria de Fernando Colón, a livraria de D. Teodósio foi uma das grandes livrarias do Renascimento. Palavras-chave: Inventários; Livrarias; D. Teodósio, duque de Bragança.

Capillaria hepatica-induced hepatic fibrosis in rats: paradoxical effect of repeated infections

Multiple exposures to parasitic agents are considered an important factor in the genesis of the most severe forms of the diseases they cause. Capillaria hepatica-induced septal fibrosis of the liver in rats usually runs without signs of portal hypertension or hepatic failure. After determining the hepatic profile of 15 animals during the course of a single infection, we submitted 20 rats to multiple Capillaria hepatica infections to determine whether repeated exposures would augment fibrosis production, transforming septal hepatic fibrosis into a true cirrhosis. Ten single-infection rats served as controls. A total of 5 exposures, with 45-day intervals, were made. Histological changes were followed by means of surgical liver biopsies, collected prior to infection and to each re-infection. Functional changes were minimal and transient. Although a slight recrudescence of fibrosis was observed after the first two re-infections and when the single-infected control group was re-infected at the end of the experiment, subsequent re-infections failed to increase the amount of fibrosis. On the contrary, there occurred quantitative and qualitative evidence of collagen degradation and suppression of parasite development. These paradoxical results are in keeping with the hypothesis that a complex immunological modulation participates in the mechanism of hepatic fibrosis induced by Capillaria hepatica infection in rats.
