RESUMO
A 37 year old man presented with progressive dysarthria for 2 weeks. A week later he developed ataxia and bilateral cerebellar signs including intention tremors, dysmetria and dysdiadokokinesia. During evaluation for aetiology of cerebellar dysarthria, MRI brain revealed asymmetric altered signal intensities in bilateral cerebellar hemispheres and right side of pons suggesting demyelinating lesions. ELISA for Human Immune Deficiency virus-1 was positive. We kept a presumptive diagnosis of Progressive Multifocal Leukoencephalopathy (PML) on the basis of clinico-radiological picture. PML is an under investigated and under diagnosed CNS infection seen in HIV patients with advanced disease. We present an unusual case report where isolated cerebellar involvement occurred as the first AIDS defining event in the absence of appreciable immunodeficiency in a patient with previously undiagnosed HIV infection.

Amongst the illicit drugs cocaine, amphetamines and cannabis have been studied and documented well to cause myocardial infarction by different mechanisms but there is very sparse data available on myocardial involvement after heroin abuse. We report a young man who developed acute myocardial injury after heroin inhalation and alcohol binge drinking. Heroin induced cardio toxic effect and vasospasm compounded by alcohol were suspected to be the cause of this.
RESUMO
INTRODUCTION: Dengue viral infections are among the most important mosquito-borne diseases of the Indian subcontinent and have become a major global public health concern. Spread of disease has led to increased recognition of atypical manifestations apart from the classical clinical features of dengue infection. METHODOLOGY: A cross-sectional study of admitted patients suspected to have dengue infection was conducted during the monsoon and post-monsoon seasons in the year 2010. Patients who had serological confirmation of dengue infection were classified according to World Health Organization definitions of dengue fever and dengue hemorrhagic fever. Clinical and biochemical parameters were compared between the two groups. RESULTS: Out of 356 patients with suspected dengue fever enrolled in the study, 138 (39%) had serologically confirmed dengue infection. Eighty (58%) patients were males and 58 (42%) were females. Ninety-six (70%) patients had classical dengue fever while 42 (30%) had dengue hemorrhagic fever. The most common symptoms were headache (105, 76%), abdominal pain (87, 63%), vomiting (80, 58%), rash (36, 26%), and cutaneous hypersensitivity (22, 16%). Hemorrhagic manifestations were present in 55 (40%) patients. Atypical manifestations were recorded. Notably, 14% of patients had neurological involvement and 4% had acute hepatic failure. Overall mortality was 6% and all fatal cases were due to multi-organ failure. CONCLUSION: Dengue infection poses a huge burden to the health-care system; its spectrum ranges from mild self-limiting illness to severe fatal disease. It can have varied and multi-systemic manifestations which can go unrecognized. Clinicians should have a high index of suspicion for atypical manifestations.
