Clinical Trial Controlled Clinical Trial
Dysregulation of apoptosis in scorpion envenomed children: its reflection on their outcome.
In the present study, 46 children in Upper Egypt (less than 13 years old) were admitted to the Pediatric Intensive Care Unit for scorpion envenomation. They were compared with 20 apparently healthy children of matching age and sex as controls. Out of the studied victims, 25 children (54%) showed signs of severe envenomation and multiple organ dysfunction (MOD), while 21 victims (46%) showed signs of mild envenomation. ⋯ This dysregulation of apoptosis was increased with the severity of scorpion envenomation and its extent increased as MOD score and outcome increased. Therefore, sFas and Bcl-2 may be of value in predicting the outcome of these cases. The increase of the extent of apoptosis detected in this study seems to play a role in the outcome of scorpion envenomation, and hence, should be taken into consideration for strategies of therapeutic regimen.

Case Reports
Pulmonary haemorrhage causing rapid death after Bothrops jararacussu snakebite: a case report.
A 36-year old woman was bitten on the left ankle by a Bothrops jararacussu, and died 45 min after the bite. At necropsy, there were local signs of envenoming with haemorrhage, thrombosis and necrosis of the subcutaneous and muscular tissue. ⋯ Pulmonary haemorrhage probably secondary to the action of haemorrhagins, consumption coagulopathy and disseminated intravascular coagulation was the immediate cause of death. Intravenous inoculation of the venom could have occurred in the present case, which would explain the rapid onset of coagulation disorders, haemorrhage and death.
