Rotavirus was detected in all age groups with a predominance in 7-12 month age groups, and a higher incidence in non-nationals. There was a marked increase in the number of positive cases during the months when the relative humidity was low (25-45%) and there was no rainfall. These findings are discussed in relation to the epidemiology and prophylaxis of rotavirus infections.
Neurological manifestations like encephalitis, especially hemorrhagic encephalitis, are rarely described in dengue fever (DF), and the gamut may affect any part of the central or peripheral nervous system. Herein, we report two cases from Northern India, presenting with fever and altered sensorium, subsequently diagnosed with DF. Imaging studies revealed hemorrhagic encephalitis in both of them but one of them had a grave outcome, unfolding the fatal nature of the disease. The report enlightens DF as an unusual etiology of encephalitis and the importance of considering the infirmity as a differential in patients with neurological manifestations.
Patients with snakebites have highly variable presentations, and delayed diagnosis may lead to unfavorable outcomes. Here, we describe the case of a snakebite in a 23-year-old male who presented with myokymias. On management with mechanical ventilation and anti-snake venom, the patient improved and was discharged. The presence of myokymias may be an early clue to diagnosis and the need for mechanical ventilation in a patient with a snakebite.
Polymyositis is an uncommon inflammatory disease that causes muscle weakness affecting both sides of the body, typically the proximal muscles. Most commonly, it affects adults in their 30s, 40s, or 50s. Signs and symptoms usually develop gradually, over weeks or months. Raised creatinine phosphokinase (CPK) levels are commonly seen during the acute phase. The electromyogram characteristically shows a myopathic pattern. The affected muscles histopathologically demonstrate endomysial inflammation, lymphocytic infiltration, zonalmyofibrillar loss, and perifascicular atrophy. We report a male patient with a classical presentation of polymyositis.
