Perforation of Meckel's diverticulum in infancy

Nine infants underwent operations for perforation of a Meckel's diverticulum over a 21-yr period. All of the infants were acutely ill when initially seen by the surgical service. Lethargy, irritability, anorexia, fever, abdominal tenderness, and passage of blood in the stools were common clinical manifestations. The preoperative diagnosis of perforated Meckel's diverticulum was not made in any of the cases. Skilled preoperative and postoperative management is important for the survival of these infants. There was no mortality and minimal morbidity. In retrospect, the peptic etiology of perforation in this age group is a key to early recognition. The past history of most of the patients includes previous episodes of blood in the stools and episodic abdominal complaints.     

Diagnosis and management of scrofula in children

Atypical myobacterial infection in humans appears to be of low virulence and is acquired from the environment with no evidence of transmission ever from human contact. The majority of infected patients are never symptomatic and the disease is self-limited. When symptomatic disease does occur, it is usually in children. Treatment should be confined to patients with symptomatic cervical adenitis; surgical excision of the subcutaneous abscess and of the offending caseous lymph node is sufficient. Adjacent hyperplastic nodes should not be excised, and chemotherapy is not indicated.     

Comparison of 4% chlorhexidine gluconate in a detergent base (Hibiclens) and povidone-iodine (Betadine) for the skin preparation of hemodialysis patients and personnel

The abnormal cutaneous flora of hemodialysis (HD) patients might contribute to their frequent septic complications. We compared the effects of 13 wk of Betadine and 13 wk of Hibiclens on the skin flora of HD patients and personnel. Skin cultures were obtained weekly immediately prior to the disinfection, preceding each triweekly HD treatment, and monthly, at 2 and 4 hr postdisinfection. Total bacterial counts from predisinfection cultures were not significantly altered over either 13-wk treatment period. Hibiclens reduced total bacterial counts (p less than 0.01) and eradicated cutaneous staphylococci (p = 0.032) at both 2 and 4 hr postdisinfection significantly more than did Betadine. No reduction of staphylococcal sensitivity to either germicidal agent could be demonstrated. Neither agent was associated with severe adverse reactions and Hibiclens could not be detected in the blood. Hibiclens appears to offer short-term advantages over Betadine in the HD setting because of significantly longer duration of antibacterial activity.     

Agenesis of the dorsal mesentery without jejunoileal atresia (“apple peel small bowel”)

Agenesis of the dorsal mesentery with apple peel or Christmas tree deformity but without small-bowel atresia can occur beyond the neonatal period. The recognition of this entity is imperative as it is also associated with a marginal artery which may be the only blood supply to the majority of small bowel. Preservation of this vessel is necessary to avoid catastrophic bowel death.
