The exact relation between body temperature and mortality of acute stroke victims is poorly understood. However, body temperature can affect the outcome of stroke cases in relation to mortality. In the initial (4-12 hrs) hours of stroke, the temperature rise is often neurogenic in origin and mortality is also higher with raised body temperature. Though the anatomical lesion or nature of lesion along with other established risk factors influence the mortality of stroke cases, change in temperature does affect the outcome of stroke cases. We sought to find out the significance of stroke victim's body temperature (within 4-12 hrs) with respect to short-term mortality rate in our study. ⋯ Hyperthermia in acute stroke victim carries a bad prognostic parameter in short term basis.

The common indications for therapeutic bronchoscopy include relief of benign and malignant airway stenosis, in the intensive care unit, foreign body removal and management of hemoptysis. Debulking of airway tumors may be undertaken using techniques such as laser photoresection, electrocautery, cryotherapy, argon plasma coagulation or mechanically using rigid bronchoscopy. These techniques are often used in combination. ⋯ Certain stent types may also physically prevent (Silicone and covered metallic stents) the encroachment of tumor tissue into the airways. Covered metallic airway stents are safe and effective in the management of malignant tracheoesophageal fistulae, reduce the risk of recurrent aspiration and provide enhanced quality of life by allowing resumption of oral nutrition. In this article, we present an overview of application and the current methods available to perform therapeutic bronchoscopy.

ReviewFree radicals and antioxidants in human health: current status and future prospects.
Free radicals and related species have attracted a great deal of attention in recent years. They are mainly derived from oxygen (reactive oxygen species/ROS) and nitrogen (reactive nitrogen species/RNS), and are generated in our body by various endogenous systems, exposure to different physicochemical conditions or pathophysiological states. Free radicals can adversely alter lipids, proteins and DNA and have been implicated in aging and a number of human diseases. ⋯ Current research reveals the different potential applications of antioxidant/free radical manipulations in prevention or control of disease. Natural products from dietary components such as Indian spices and medicinal plants are known to possess antioxidant activity. Newer and future approaches include gene therapy to produce more antioxidants in the body, genetically engineered plant products with higher level of antioxidants, synthetic antioxidant enzymes (SOD mimics), novel biomolecules and the use of functional foods enriched with antioxidants.

Randomized Controlled Trial Clinical TrialRational use of anti-snake venom (ASV): trial of various regimens in hemotoxic snake envenomation.
Viperine snake bites cause hemotoxicity in the form of coagulation dysfunction. Optimal dose requirement of anti-snake venom (ASV) and duration of therapy in such situation have not yet been fully explored. Our aim in this study was to compare two low-dose continuous infusion regimes with the standard high dose intermittent bolus regime in treating systemic envenomation and preventing its recurrence. ⋯ Regimens consisting of continuous intravenous infusion of ASV i.e., Regimen II in mild envenomation and Regimen III in moderate and severe envenomation are likely to make significant saving of ASV and reduction of recurrence of coagulation dysfunction.

Case ReportsTwo cases of valproate-induced hyperammonemic encephalopathy without hepatic failure.
We report two children with localization related epilepsies, who presented with somnolence, seizure exacerbation, behavioral alteration, decline in speech and cognitive abilities, and ataxia while being treated with a combination of valproate and topiramate, but had previously tolerated valproate with other antiepileptic drugs. These children had elevated serum ammonia, normal transaminase levels, and generalized slowing of EEG background activity during encephalopathy, which promptly reverted back to normal along with clinical improvement following withdrawal of valproate. To our knowledge, this is the first documentation of valproate-induced hyperammonemic encephalopathy enhanced by topiramate from India. We intend to alert internists, pediatricians, psychiatrists and neurologists about this underrecognized adverse effect of antiepileptic drug polytherapy.
