Antimicrobial constituents of the leaves of Acalypha wilkesiana and Aacalypha hispida.

An activity directed fractionation of a 50% aqueous ethanol extract of A. wilkesiana and A. hispida leaves resulted in the isolation of gallic acid, corilagin and geraniin as the compounds responsible for the observed antimicrobial activity. Quercetin 3-O-rutinoside and kaempferol 3-O-rutinoside were also isolated from the inactive fraction of A. hispida. The structures were established by permethylation, 2D - NMR ((1)H and (13)C) and MS data.

Clostridium difficile colitis associated with infant botulism: near-fatal case analogous to Hirschsprung's enterocolitis.

We present the first five reported cases of Clostridium difficile-associated diarrhea (CDAD) in children with infant botulism caused by Clostridium botulinum. We compare two fulminant cases of colitis in children with colonic stasis, the first caused by infant botulism and the second caused by Hirschsprung's disease. In both children, colitis was accompanied by hypovolemia, hypotension, profuse ascites, pulmonary effusion, restrictive pulmonary disease, and femoral-caval thrombosis. Laboratory findings included pronounced leukocytosis, hypoalbuminemia, hyponatremia, coagulopathy, and, when examined in the child with infant botulism, detection of C. difficile toxin in ascites. CDAD recurred in both children, even though difficile cytotoxin was undetectable in stool after prolonged initial therapy. Four children who had both infant botulism and milder CDAD also are described. Colonic stasis, whether acquired, as in infant botulism, or congenital, as in Hirschsprung's disease, may contribute to the susceptibility to and the severity of CDAD.

Ectopic pancreas as the cause of gastric outlet obstruction in a newborn.

This case of ectopic pancreas found in the pre-pyloric channel of a 2-day-old infant is unique. A review of the literature reveals no other cases of symptomatic ectopic pancreas in an infant of this age. In this patient, signs and symptoms were consistent with pyloric stenosis. Upper gastrointestinal study and esophagogastroduodenoscopy (EGD) revealed the diagnosis. This case is examined and the literature is reviewed.

Partial splenectomy in children under 4 years of age with hemoglobinopathy.

BACKGROUND/PURPOSE: The risk of septicemia in postsplenectomy pediatric patients is approximately 2%. This risk is twice as great for children less than 4 years of age. In the first year of life this risk can be 30% or higher. Partial splenectomy is an alternative in patients with hemoglobinopathies. The authors attempt to assess the outcome of pediatric patients less than 4 years of age undergoing partial splenectomy using the Argon beam. METHODS: In a tertiary care, university affiliated, dedicated children's hospital seven patients underwent partial splenectomy (PS) by the same surgeon from May 1993 to September 1995. The PS performed for trauma was excluded. Included were patients with hemoglobinopathies. Therefore, six patients were evaluated. Follow-up was from 6 months to 2 years. Pre- and postoperative blood transfusions, length of operation, estimated blood loss, length of hospital stay, postoperative complications, perfusion, and function of remnant spleen were evaluated. RESULTS: Indications for splenectomy included sequestration crisis and hypersplenism. Percent splenectomy ranged from 65% to 75%. Average hospital stay was 6.3 days. Postoperative splenic function, measured by Pitt count and radionuclide spleen scan, was normal. Postoperatively there were no systemic infections, overwhelming postsplenectomy sepsis (OPSS), torsion of the splenic remnant, left upper quadrant fluid collections, or subphrenic abscesses. There were no deaths. CONCLUSIONS: Partial splenectomy is a safe and effective procedure in children less than 4 years of age with hemoglobinopathies. The procedure as described yields minimal blood loss and retains immune competence. Partial splenectomy greatly reduces, and in some cases eliminates, the need for blood transfusions. PS should be considered the procedure of choice in children less than 4 years of age with sickle cell anemia or beta-thalassemia who require splenectomy.

Cholecystectomy in sickle cell anemia patients: perioperative outcome of 364 cases from the National Preoperative Transfusion Study. Preoperative Transfusion in Sickle Cell Disease Study Group.

Cholecystectomy is the most common surgical procedure performed in sickle cell anemia (SCA) patients. We investigated the effects of transfusion and surgical method on perioperative outcome. A total of 364 patients underwent cholecystectomy: group 1 (randomized to aggressive transfusion) 110 patients; group 2 (randomized to conservative transfusion) 120 patients; group 3 (nonrandomized nontransfusion) 37 patients; and group 4 (nonrandomized transfusion) 97 patients. Patients were similar except group 3 patients were more likely to be female, over 20 years old, smokers, and more healthy by American Society of Anesthesiologists (ASA) physical status score. Total complication rate was 39%: sickle cell events 19%; intraoperative or recovery room events 11%; transfusion complications 10%; postoperative surgical events 4%; and death 1%. Group 3 patients had the highest incidence of sickle cell events (32%). Open cholecystectomies were performed in 58% and laparoscopic in 42%. Laparoscopic patients were younger and more healthy by ASA score. Laparoscopic patients had longer anesthesia time (3.2 v 2.9 hours), but shorter hospitalization time (6.4 days v 9.8). Complications were similar between these two groups. We conclude that SCA patients undergoing cholecystectomy have a high perioperative morbidity, and the incidence of sickle cell events may be higher in patients not preoperatively transfused. We recommend a conservative preoperative transfusion regimen, and we encourage the use of the laparoscopic technique for SCA patients undergoing elective cholecystectomy.

Sand aspiration: a case report.

There have been few documented cases of sand aspiration. The authors report on a 3-year-old boy who suffered severe respiratory compromise secondary to sand aspiration. Emergency intubation and subsequent bronchoscopy were required to relieve airway obstruction. The patient did well and suffered no long-term sequelae.
