Hemorrhagic encephalopathy in dengue shock syndrome: a case report

Dengue fever is the most important arboviral infection in the world, with an estimated 100 million cases per year and 2.5 billion people at risk. Encephalopathy is a rare complication of dengue virus infection and may occur as a consequence of intracranial hemorrhage, cerebral edema, hyponatremia, cerebral anoxia, fulminant hepatic failure with portosystemic encephalopathy, microcapillary hemorrhage or release of toxic products. We report a rare case of hemorrhagic encephalopathy in dengue shock syndrome caused by type 3 dengue virus.

Doença de Castleman multicêntrica / Multicentric Castleman's disease

A doença de Castleman (DC) é uma rara desordem linfoproliferativa de origem desconhecida. É classificada histologicamente em três tipos: hialinovascular, o mais comum, células plasmocitárias e mista. O tipo hialinovascular é usualmente caracterizado por um curso benigno sem apresentar sintomas sistêmicos. Relataremos o raro caso de um paciente de 45 anos com doença de Castleman tipo hialinovascular com queixas de emagrecimento e fraqueza muscular de dois anos de evolução

Aminotransferase changes and acute hepatitis in patients with dengue fever: analysis of 1, 585 cases

INTRODUCTION: Type 3 dengue virus caused an extensive epidemic in the state of Rio de Janeiro in summer 2002. In some of the patients, it was found in an atypical form with increased aminotransferase levels and acute hepatitis. MATERIAL AND METHODS: An analysis was made of 1,585 serologically confirmed dengue cases at the Dengue Reference Center in Campos dos Goytacazes, Rio de Janeiro state. The grade of hepatic aggression was established according to the alterations in the aminotransferase levels: grade A - normal levels of aminotransferase; grade B - elevated aminotransferase, with increased levels of at least one of the enzymes; grade C - elevated aminotransferase, with the levels of at least one of the enzymes increased to more than three times the reference values; grade D - acute hepatitis, with aminotransferase levels increased to at least 10 times their normal values. RESULTS: Among the 1,585 serologically confirmed dengue cases, 44.5 percent presented alterations in the aminotransferase levels (grade B), 16.9 percent presented grade C liver involvement and 3.8 percent of the patients had progressed to acute hepatitis (grade D). The average values for the rise in aspartate aminotransferase and alanine aminotransferase were 93.3 U/L and 86.0 U/L. The greatest alterations were observed among females (p<0.001), cases of dengue hemorrhagic fever (p<0.001), and cases with sequential infections (p=0.001). CONCLUSIONS: Liver damage with elevation of aminotransferases and reactive hepatitis was a common complication of dengue virus infection in these patients.

Granulomatose de Wegener e mononeurite múltipla / Wegener granulomatosis and mononeuritis multiplex

A granulomatose de Wegeber (GW) é uma vasculite sistêmica de pequenos vasos que se caracteriza pela tríade clássica de sinusite, vasculite sistêmica e acometimento renal. Neste relato apresentamos um caso de granulomatose de Wegener em uma paciente de 48 anos com história pregressa de sinusite de longa data e estenose subglótica, que apresentou quadro de mononeurite múltipla e púrpura palpável.

Doença de Von Recklinghausen e feocromocitoma / Von Recklinghausen`s disease and pheochromocytoma

A doença de Von Recklinghausen (Neurofibromatose tipo I) tem como uma de suas características a associaçäo com doenças neoplásicas, dentre elas o feocromocitoma. Neste artigo é apresentado o caso de um paciente de 36 anos, portador de neurofibromatose de Von Recklinghausen, associada a feocromocitoma, que procurou atendimento médico para esclarecinento de hipertensäo arterial e tumor abdominal doloroso.

Hepatitis in Dengue Shock Syndrome

Dengue fever is the most frequent arbovirus disease in the world and the most important one in terms of morbidity and mortality. Atypical manifestations of dengue have become commonplace during the last few years, including hepatic damage, which manifests mainly by pain in the right hypochondrium and an increase in the levels of aminotransferases. We describe a case of acute hepatitis in a patient with Dengue Shock Syndrome Grade III. We analyzed the clinical and laboratory aspects of this atypical complication of dengue as well as the differential diagnoses.
