Ten years' experience with pediatric gunshot wounds.

Gunshot wounds in children have become a significant source of morbidity and mortality in our community in the last 10 yr. One hundred eight children, 16 yr of age and younger, were admitted to the Pediatric Surgical Service for gunshot wounds during this period; only 1 child was admitted for a gunshot wound in the 10 yr preceding this review. Rapid resuscitation and triage of major injuries directly to the operating room achieved a 94% survival. Review of the circumstances of injury revealed that 42% of the gunshot wounds were inflicted by children and 40% were known to have been intentional. Only 20% of the patients had known drug involvement; in general this was involvement in drug selling, not in drug abuse. Social service intervention can offer significant benefit to these children, but ultimately gun control laws with strict enforcement are needed to stop this type of violence toward children.

The role of platelet surface proteins reacting with heterologous antibodies.

Platelets were labeled with surface-labelling agents which identified up to six platelet membrane proteins. Three of these labelled proteins were recognised by a specific anti-platelet membrane serum by immunoprecipitation. Affinity fractionation of platelets with insolubilised IgG obtained from the anti-platelet membrane serum indicated a greater reaction between the antiserum and the platelet surface. Fab fragments from the antiserum inhibited ristocetin-induced aggregation of platelets and partially inhibited collagen-induced aggregation but did not affect ADP aggregation. Crossed immunoelectrophoresis of platelets using the anti-platelet membrane serum showed that the antiserum was specific for platelet membranes.

Renal artery thrombosis following blunt trauma.

Renal artery thrombosis after blunt trauma presented without other injury, without external signs of trauma, and without hematuria in the case reported. Review of 65 cases from the literature showed that flank and epigastric pain and proteinuria are usually present. Renal artery thrombosis following blunt trauma has usually been diagnosed too late to salvage the kidney. Nephrectomy is performed for ileus, fever, and pain caused by the necrotic kidney, or for hypertension. Ideally, rapid diagnosis by intravenous pyelogram and arteriography and early surgical intervention should allow revascularization and renal salvage before permanent parenchymal damage has occurred. The cases reviewed showed that successful revascularization without hypertension could be achieved 12 hours after injury. Patent small collateral vessels as well as incomplete or gradual renal artery occlusion may prolong renal salvage time.

Vascular occlusion and stricture of the sigmoid colon secondary to trauma from a pneumatic hammer.

A patient with stricture of the descending colon secondary to use of a pneumatic hammer is presented. Barium enema and angiographic studies suggested that the etiology was a traumatic vascular injury. Barium granulomata, found in the resected specimen, were presumably due to barium having entered the devitalized tissues during an air contrast study performed during an acute ischemic colitis. The mechanisms of traumatic strictures of the colon are discussed.

Protection against experimental necrotizing enterocolitis by maternal milk. I. Role of milk leukocytes.

A rat model of necrotizing enterocolitis of the neonate in which maternal milk had been protective was studied to determine what components of the milk afforded protection and by what mechanism. Frozen and thrawed rat milk was not protective, but formula supplemented with rat milk cells was. It was concluded that the cells provided protection. The cells, which are principally mononuclear phagocytes, can phagocytize and kill the Klebsiella pneumoniae strain used in the animal model. Animals with necrotizing enterolitis had peritonitis and bacteremia caused by this bacillus.

Necrotizing enterocolitis in term infants.

Despite the fact that necrotizing enterocolitis is considered a disease of premature infants, 20% of all affected infants at Babies Hospital over the past 20 years were products of term gestations. Two distinct subgroups of such infants were noted (1) five infants with congenital heart disease and/or congestive heart failure (e.g.hypoplastic left heart syndrome), all but one of whom developed the disease in the first week of life; (2) eight infants who developed the disease at a much later age after a protracted period of diarrhea. This histopathologic features of the disease in term infants are the same as those in premature infants. Further, the pathogenesis of the disease in term infants does not appear to differ basically from that in premature infants. These facts, lead away from the concept of NEC as a disease of simple etiology.

Choledochal cyst: a review of 19 cases.

Nineteen cases of choledochal cyst are reviewed. Two distinct groups of patients were identified. Patients under one year of age, initially diagnosed as having biliary atresia, had a higher mortality rate, a higher incidence of severe cirrhosis with portal hypertension, and associated atresia or stenosis in the biliary tree. The second group, presenting between 3 and 20 years of age with more classic symptoms, had mild cirrhosis without portal hypertension and had associated choledocholithiasis and pancreatitis. It is suggested that the younger patients had a congenital form of cystic bile duct dilatation and that the older patients had an acquired form, perhaps related to a common channel with reflux of pancreatic juice into the common bile duct. Postoperative follow-up supports the current view that choledochocyst-jejunostomy with choleystectomy has a lower rate of long-term complications than does choledochocyst-duodenostomy.

Acute necrotizing enterocolitis in infancy: a review of 64 cases.

Sixty-four cases of necrotizing enterocolitis are reviewed. The diagnosis was based on tissue examination in 57 and on the clinical syndrome, including pneumatosis, in 7. Three factors are important in the development of the disease: injury to the intestinal mucosa, bacteria, and feedings. The indications for surgical intervention are pneumoperitoneum, signs of peritonitis, and intestinal obstruction. The importance of stress in the etiology of the disease is confirmed by the high incidence of perinatal complications, particularly hypoxia. The mortality was high, but results are improving with the institution of early aggressive treatment.

Importance of multiple episodes of hypoxia or cold stress on the development of enterocolitis in an animal model.

Necrotizing enterocolitis, a highly lethal disease in the newborn infant characterized by ischemic necrosis of the gastrointestinal tract frequently leading to perforation, is seen primarily in low birth weight infants who have undergone stress, such as hypoxia. In an animal model it was demonstrated that cold stress was as effective as hypoxia in producing the disease in formula-fed newborn rats. Breast milk was completely protective in both cold- and hypoxic-stressed animals. Presumably cold stress produces the same selective circulatory ischemia as does hypoxia. The experiment further supports the concept that any insult or stress which decreases mesenteric blood flow may initiate the changes leading to necrotizing enterocolitis. It was shown also that the incidence of the disease in formula-fed rats was related directly to the number of episodes of either cold or hypoxic stress. These results suggest that a critical amount of ischemia is necessary to initiate these changes and may help to explain the fact that not all infants exposed to hypoxia or cold stress developthe disease.
