A 16-year-old boy ingested approximately 50 zinc sulfate tablets (ZnSO4; 500-mg tablets). After spontaneous emesis, ipecac-induced emesis, and orogastric lavage, an abdominal radiograph performed four hours after ingestion still demonstrated approximately 50 ZnSO4 tablets within the stomach and three pills within the colon. Whole-bowel irrigation was begun with a polyethylene glycol lavage solution (PEG; Golytely) that was administered through a nasogastric tube; within one hour, the patient began producing a rectal effluent that contained pills. ⋯ Stool guaiac tests were negative. The serum chloride, however, increased from 105 to 127 mEq/L. Follow-up kidney, ureter, and bladder studies demonstrated the clearance of the zinc tablets from the gastrointestinal tract during the next 24 hours.

We report the cases of a child who ingested two or more castor beans and two adults who each ingested four beans. All three patients developed severe gastroenteritis and recovered without sequelae after receiving IV fluids. The literature contains reports of 424 cases of castor bean intoxication. ⋯ After decontamination and activated charcoal, symptomatic patients require hospitalization for treatment with IV fluids, supportive care, and monitoring for hypoglycemia, hemolysis, and complications of hypovolemia. Monitoring for delayed cytotoxicity is unnecessary. Castor beans and their dust are highly allergenic and may cause anaphylaxis.

To examine the effect of administration of oral activated charcoal with or without sorbitol on the elimination of phenytoin. ⋯ Oral activated charcoal was shown to affect phenytoin pharmacokinetic parameters. Further pharmacokinetic/pharmacodynamic studies are warranted to determine if activated charcoal results in a faster recovery from phenytoin toxicity.

To correlate cerebral arterial blood velocity measurements as determined by transcranial Doppler ultrasound with various resuscitation maneuvers performed in an uncontrolled manner in a series of cardiac arrest patients undergoing standard resuscitation. ⋯ Transcranial Doppler ultrasound appears to be a potentially promising means of determining cerebral flow in patients undergoing CPR.
