A clinical review was made on 2,191 cases of general pediatric surgery under the age of 15 years which were operated upon at the Divisionof Pediatric Surgery, Department of Surgery, Chonnam University Hospital from January 1988 to December 1997. The number of operations in pediatric age were 13,144 (13.2%) out of total 99,555 operations at Chonnam University Hospital and the most prevalent age group was under 1 year of age (14.3%). The number of operations in Divisionof General Pediatric Surgery were 2,191 (16.7%) out of total 13,144 operations in pediatric age and the incidence of patients under 1 year of age in general pediatric surgery was 42.9% (941/2,191). The prevalent diseases under 1 month of age were anorectal malformations (20.6%) and hypertrophic pyloric stenosis (20.3%) and between 1 month to 1 year of age were inguinal hernia (32.4%) and intussusception (19.6%). The total motality rate in neonatal intensive care unit was 31.3%. Gastroschisis presented highest mortality.

Eosinophil degranulation is considered to be a key effector function for the killing of helminthic worms and tissue inflammation at worm-infected lesion sites. However, relatively little data are available with regard to eosinophil response after stimulation with worm-secreted products which contain a large quantity of cysteine proteases. In this study, we attempted to determine whether the degranulation of human eosinophils could be induced by the direct stimulation of the excretory-secretory products (ESP) of Paragonimus westermani, which causes pulmonary paragonimiasis in human beings. Incubation of eosinophils for 3 hr with Paragonimus-secreted products resulted in marked degranulation, as evidenced by the release of eosinophil-derived neurotoxin (EDN) in the culture supernatants. Moreover, superoxide anion was produced by eosinophils after stimulation of the ESP. The ESP-induced EDN release was found to be significantly inhibited when the ESP was pretreated with protease inhibitor cocktail or the cysteine protease inhibitor, E-64. These findings suggest that human eosinophils become degranulated in response to P. westermani-secreted proteases, which may contribute to in vivo tissue inflammation around the worms.

Since Green et al has introduced a new technique of retrograde intramedullary nail, the use of retrograde interlocking intramedullary nails has been recommended as one of the treatment options for the distal femoral fracture. However there are some disadvantages that an arthrotomy is required for insertion and the knee joint could often be violated. Authors present a simple, arthroscopically assisted method using the retrograde intramedullary nailing for distal femoral fractures with minimal invasiveness to the knee. From March 1995 to March 1997, the retrograde intramedullary nail was used to treat 9 distal femoral fractures. Five of 9 patients were fractured at the distal shaft of the femur and others were fractured at the supracondylar region of the femur. Only one of the fractures was open injury(Gustilo-Anderson grade II). Significant concomitant knee joint injuries were revealed through the arthroscopy in 3 patients. Eight of 9 fractures healed by 5 months, but one fracture was not healed and required bone grafting. Average knee range of motion was 130. Complications included 1 nonunion and 1 hardware failure. There were no patellofemoral problems and no posttraumatic arthritis of the knee joint. This arthroscope-assisted method have some potential benefits that include decreased risk of damage to the knee joint, early evaluation and treatment of the associated knee joint injuries, and accurate placement of the nail.

BACKGROUND: Insulin resistance syndrome shows extreme insulin resistance and is associated with acanthosis nigricans. We can differentiate it into type A insulin resistance that has insulin receptor defect, and type B insulin resistance due to insulin receptor autoantibody. Type B insulin resistance was firstly described by Kahn in 1976. It was often found in adult female and showed autoimmune characteristics. As clinical characteristics, there are hyperglycemia, hypoglycemia, hyperinsulinemia, extreme insulin resistance and acanthosis nigricans. METHODS: We investigated 17 insulin receptor autoantibody positive cases and 8 cases of normal control who had visited Wonju Christian Hospital from October 1994 to December 1995. Among insulin receptor autoantibody positive subject, male was 4 cases and female 13 cases. Their mean age was 42.2. We compared patients who had insulin receptor antibody positive acanthosis nigricans(IRA) with normal controls. IRA patients were 6 cases(35.3%) of nomal glucose tolerance, 11 cases(64.7%) of abnormal glucose tolerance including overt diabetes mellitus. RESULTS: The 11 cases(64.7%) among IRA patrents were obese and 13 cases(76.5%) had hyperininsulinemia. In IRA patients, mean serum insulin concentration during oral glucose tolerance test was 202.1mU/mL and it was greater than 46.3 of normal controls. Insulin sensitivity in 1.79mg/L * mM * xmU * min normal controls was higher than 0.74mg/L * mM * min of IRA patients. CONCLUSION: IRA patients showed abnormal glucose tolerance including overt diabetes millitus, severe insulin resistance, hyperinsulinemia and obesity.

BACKGROUND: Since percutaneous mitral valvuloplasty(PMV) using balloon was introduced by Inoue in 1984, this procedure has been accepted as a new non-surgical therapeutic modality for the treatment of selected patients with mitral stenosis. Pregnant women with mitral stenosis has suffered from life threatening complication due to altered hemodynamic changes and heart failure. Surgical valvotomy has been performed after failure of medical therapy with high risk of fetal mortality and teratogenicity. PMV can be an adequate alternative to surgical valvotomy in pregnant women. METHODS: After precise echocardiographic examination of mitral valve and its surrounding structures including thrombi in left artrium was performed, antegrade transseptal procedure was done in all 3 cases with abdominal shield using Inoue balloon technique. RESULTS: Mitral valve area increased over 1.5cm2 and hemodynamic variables improved immediately after PMV. Symptoms subsided soon after PMV in all 3 cases. Healthy normal babies were delivered transvaginally without difficulties in all 3 patients. CONCLUSIONS: Percutaneous mitral valvuloplasty is a safe and effective therapeuteic alternative to surgical valvotomy in a pregnant women with mitral stenosis who failed medical therapy, in a high risk or symptomatic pregnant women.
