ABSTRACT
Um episódio de delirium após sangramento intestinal agudo é relatado em paciente masculino com 90 anos de idade. O local de sangramento, um pólipo adenomatoso no colon direito, foi identificado por de cintilografia com eritrócitos marcados com tecnécio. O paciente recebeu hemotransfusões e haloperidol, com rápida melhora antes daressecção endoscópica do pólipo. Este relato visa a aumentar o alerta dos clínicos gerais acerca do delirium, uma condição comum entre idosos, que pode representar alta morbidade e mortalidade. A anemia deve ser incluída entre os principais fatores de risco de alterações cognitivas em idosos.
An episode of delirium after an acute intestinal bleeding is reported in a 90-year-old male. The site of bleeding was detected by technetium-labeled erythrocyte scintigraphy, and was an adenomatous polyp of the right colon. The patient received blood transfusions and haloperidol, with rapid improvement before the endoscopic resection of the polyp. This report aims is to increase the awareness of general physicians about delirium, a common condition among the oldest old that may cause high morbidity and mortality. Anemia should be included among the main riskfactors of cognitive decline in elderly.
ABSTRACT
Dengue is an arthropod-borne disease caused by viruses of Flaviviridae family. It poses a major public health burden in tropical and sub-tropical regions. Clinical features of dengue vary from a mild flu-like disease and rash, to a potentially lethal haemorrhagic fever or shock syndrome. Hantavirus pulmonary syndrome is a rodent-born disease emerging in the American continent and is caused by viruses of the Bunyaviridae family. Potential reservoirs of these agents were described in Brazilian Central Plateau. Dengue infection is transmitted by mosquitoes, while hantaviruses are acquired by contact or inhalation of aerosolised excreta of infected rodents. Dengue and hantavirus infections have also been considered as emerging public health problems in some Indian areas; moreover, other infections mixed with dengue have been documented. The case of a Brazilian patient with hantavirus pulmonary syndrome and serologic evidence of dengue infection is described.
