Clinical Trial
Continuous thoracic epidural infusions for postoperative analgesia after pectus deformity repair.
To determine whether continuous epidural analgesia after repair of a pectus deformity is a viable and safe alternative to high-dose narcotics in children. ⋯ Thoracic epidural analgesia was completely successful in nine (53%) children who underwent repair of pectus deformity, and effectively reduced the intravenous narcotic demand in the other eight. Pain control was excellent, and no catheter-related complications were encountered. The data show that this method of analgesia in children is a safe and attractive alternative to intravenous narcotics, and eliminates the potential disadvantages of sedation and respiratory compromise.

Recently it has become possible to identify persons who have multiple endocrine neoplasia (MEN) syndrome types 2A and 2B based on the presence of missense mutations in the RET protooncogene. Kindred members who have inherited these syndromes can be identified before clinical or biochemical evidence of medullary thyroid carcinoma (MTC) develops, the malignancy that occurs in all affected patients. It is not known whether prophylactic removal of the thyroid gland early in childhood, based on a positive genetic test result, has a better clinical outcome than that associated with thyroidectomy after MTC is diagnosed clinically or biochemically. ⋯ The authors conclude that a significant number of patients with MEN 2A or 2B who undergo thyroidectomy in childhood for MTC have persistent or recurrent disease long-term. The genetic diagnosis of patients with these syndromes may allow for prophylactic surgery before the development of biochemical or clinical evidence of MTC. This approach is safe, but longer clinical follow-up will be necessary to confirm that MTC has been cured.

Islet autotransplantation can prevent surgically induced diabetes after total pancreatectomy in adults; however, the efficacy of this procedure has not been established in children. The authors report the case of a 12-year-old boy who underwent total pancreatectomy and islet autotransplantation for intractable pain caused by idiopathic chronic pancreatitis. Islets were prepared from the excised pancreas by collagenase digestion and mechanical dispersion. ⋯ Thus, exogenous insulin supplementation was needed to prevent hyperglycemia. In conclusion, insulin independence was initially established in a child by islet autotransplantation after total pancreatectomy. The failure of the islets to maintain normoglycemia long-term suggests that a sufficient number must be transplanted (to meet the demands of normal growth and development) for sustained insulin independence.

The mortality rate for pediatric trauma patients cared for in adult trauma centers has been shown, by means of TRISS methodology, not to differ significantly from that of the Major Trauma Outcome Study (MTOS). The question remains, however, whether the outcome of injured children is better in a designated pediatric trauma center (DPTC). The authors' hypothesis is that outcome is better at a DPTC. ⋯ Children with BT have a significantly better outcome at a DPTC; the outcome for children with PT does not differ. Successful nonoperative treatment of blunt abdominal injuries is more likely to occur at a DPTC than at adult trauma centers "with pediatric committment." Thus, children with blunt injuries should be taken to a DPTC, when available.

Cardiac tamponade in the pediatric oncology population: treatment by percutaneous catheter drainage.
The treatment of pericardial effusion resulting in cardiac tamponade has undergone an evolution in recent years, with the use of less invasive drainage methods in selected cases. To determine optimal therapy for pediatric oncology patients with pericardial effusion and tamponade, the authors reviewed their institutional experience with percutaneous catheter drainage. ⋯ Cardiac tamponade was effectively treated in all patients and did not recur with percutaneous catheter drainage alone. THere was no evidence of pericardial loculation or infection despite pancytopenia being prevalent with underlying illness and chemotherapy. Percutaneous catheter drainage is an effective treatment for pediatric oncology patients with pericardial tamponade. Because of its simplicity in comparison to move invasive techniques, initial treatment with percutaneous drainage should be considered in this patient population.
