Case ReportsWound botulism acquired in the Amazonian rain forest of Ecuador.
Wound botulism results from colonization of a contaminated wound by Clostridium botulinum and the anaerobic in situ production of a potent neurotoxin. Between 1943, when wound botulism was first recognized, and 1990, 47 laboratory-confirmed cases, mostly trauma-associated, were reported in the United States. Since 1990, wound botulism associated with injection drug use emerged as the leading cause of wound botulism in the United States; 210 of 217 cases reported to the Centers for Disease Control and Prevention between 1990 and 2002 were associated with drug injection. ⋯ However, wound botulism may go undiagnosed and untreated in many countries. We report two cases, both with type A toxin, from the Ecuadorian rain forest. Prompt clinical recognition, supportive care, and administration of trivalent equine botulinum antitoxin were life-saving.

Volume replacement in infants with dengue hemorrhagic fever/dengue shock syndrome.
Volume replacement was studied prospectively in 208 infants with dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS). The mean volume of intravenous fluid used was 110.4 mL/kg administered over a mean period of 25.8 hours. The mean volumes of intravenous fluid replacement in infants with DSS was significantly higher than in those with non-shock DHF (129.8 mL/kg versus 102.1 mL/kg; P = 0.001). ⋯ Four patients with DSS died of severe complications. Intravenous fluid replacement with special care to avoid fluid overload requires careful attention to established indications for use of colloidal solutions and blood transfusions. To improve case fatality rates, special efforts need to be directed to infants with DHF/DSS accompanied by severe complications.
