Snake bite poisoning is an emergency condition with significant morbidity and mortality. It is more prevalent in Terai and Inner Terai regions of Nepal especially during monsoon season. There is no study on snake bite poisoning in adults in this part of the country after the introduction of national snake bite management guideline in 2003. This retrospective study was conducted to evaluate the clinico-epidemiological profile, amount of anti-snake venom used and outcome of snake bites. Six hundred and thirty eight cases of snake bite poisoning above the age of 15 years admitted in emergency department of the hospital, over a period of 6 years from 2004/2005 to 2009/2010 were evaluated retrospectively. The study showed almost equal numbers of bites in males and females (50.3% vs 49.7%) with two third of victims of 15 to 45 years of age. Most of the poisonings (68%) was seen during June, July and August months corresponding to the monsoon season in Nepal. Majority of the victims could not identify the snakes (45 %).Fingers & hands were bitten in majority cases (43 %). Ptosis was observed in all cases of snake bite poisoning. About 21% of the adults had respiratory distress needing respiratory support. Average ASV used was 21.3 vials. Case fatality rate (CFR) was 11.9% with more fatality on those with respiratory distress. As mortality due to snakebite poisoning and consumption of antisnake venom is still high with the use of national protocol 2003, further study to evaluate alternate protocol is recommended.
Objective: Prominent resolution in the ST segment elevation on electrocardiogram(ECG), thrombolysis at the infarction site restoring perfusion determines the effectiveness of the streptokinase therapy. Hyper- coagulable states and lack of efficacy with streptokinase is seen in diabetics. This study aimed to assess the thrombolytic efficacy of streptokinase in diabetic vs non-diabetics patients. Methods: A cross-sectional study was conducted at Cardiology Department of Allama Iqbal Memorial Teaching Hospital, Sialkot from 1st September 2019 to 30th April, 2020. Total 504 patients of which 185 diabetics and 319 non-diabetic were selected. All the patients presenting with first episode of acute ST- elevation myocardial infarction were thrombolysed with 1.5million units of streptokinase within 12hours from the onset of their typical chest pain symptoms. A complete record of ECG changes was kept before and 90 min after thrombolysis with streptokinase. Chi- square test was applied and p value <0.05 was considered significant. Results: 89.19% diabetic patients had >70% resolution of ST segment changes in comparison to 95.61% non-diabetics. 16.76% of the diabetic patients had increased ST-segment elevation post thrombolysis (P- value 0.001). 8.11% and 10.81% reinfarction rates during hospital stay and at one month post-thrombolysis were recorded in diabetics. Reduced left ventricle Ejection Fraction was seen in 62.16% and 58.62% of the diabetic and non-diabetic patients(P-value<0.005). Conclusion: Comparatively decreased efficacy of streptokinase is seen in diabetic patients with reduced resolution of ST-segment. In correspondence with reduced left ventricle EF, re-infarction and stroke episodes. Key Words: Streptokinase, acute myocardial infarction, STEMI, diabetes mellitus, hypercoagulability, atherosclerosis. How to Cite: Hassan Z., Rana N., Rana B., Iqbal I., Chughtai J.I.
