Transverse sinus thrombosis associated with otitis media and mastoiditis.

A case of transverse sinus thrombosis is described in an adolescent male with antecedent meningomyelocele corrected by surgery, and ventriculo-peritoneal derivation. Four months before the occurrence of thrombosis, he presented with bilateral otitis media and mastoiditis, and was treated with antibiotic. Magnetic resonance images were not obtained before referral to our hospital. The patient received full anticoagulation and his clinical course was uneventful. He remains asymptomatic under outpatient surveillance till this report. The aim of reporting the case is to emphasize the role of otologic infections in the origin of intracranial thrombotic phenomena, and highlights the findings of magnetic resonance venography for characterization of intracranial sinus thrombosis.

Hantavirus pulmonary syndrome coexistent with Dengue.

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.
