Non-fatal acute renal failure due to wasp stings in children

We report two children who developed acute renal failure after multiple wasp stings. Each case involved intravascular hemolysis which caused acute renal failure, volume overload, hypertension, anemia, hyponatremia, hyperkalemia, and metabolic acidosis. Peritoneal dialysis was required for short periods. The children recovered completely with blood urea nitrogen and creatinine returning to normal within 3 months. One child had a renal biopsy which showed mild tubulointerstitial nephritis. Although there is no specific treatment or antivenom, dialysis and supportive care have proved to be successful.

马蜂蜇伤中毒老年患者器官功能障碍的临床观察

目的 了解和掌握老年人马蜂蜇伤的临床特点和发病规律,以有效提高急性马蜂蜇伤的抢救成功率。方法 收集2009年1月至2013年12月竹山县人民医院收治的马蜂蜇伤病例共221例,根据年龄分为两组,老年组（年龄≥60岁）56例,非老年组（年龄＜60岁）165例,对两组患者多器官功能障碍、预后转归情况进行对比分析。结果 急性马蜂蜇伤,老年组器官功能障碍发生率依次为：肝脏55.36%,心血管32.14%,非老年组器官功能障碍发生率依次为：肝脏56.97%,心血管36.97%;老年组出现多器官功能障碍共有35例,发生率62.50%,非老年组共有94例,发生率56.97%,差异无统计学意义（P＞0.05）。多器官功能障碍死亡老年组2例,病死率5.71%,非老年组2例,病死率2.13%,差异无统计学意义（P＞0.05）。结论 本地区急性马蜂蜇伤中毒致器官功能障碍老年患者、非老年患者均以肝脏和心血管最多见;老年患者、非老年患者多器官功能障碍发生率差异无统计学意义,出现多器官功能障碍后病死率差异亦无统计学意义。     

An infarct-like myocardial lesion experimentally induced in wistar rats with Africanized bee venom

There is evidence in the literature that death following a bee or wasp sting may result from cardiac involvement. This study describes acute cardiac lesions experimentally induced in Wistar rats submitted to intravenous inoculation of Africanized bee venom (ABV) and killed 1, 4, and 24 h after inoculation. Significant increases in serum enzyme levels were detected; light microscopy showed necrosis of the myocardium; and enzyme histochemistry showed inactivation of enzymes in and around the areas of necrosis. This is the first report of an acute necrotizing cardiac lesion, similar to human myocardial infarction, produced by the inoculation of ABV.
