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.

BACKGROUND: The goal of this study was to analyze the process and characteristics of withholding or withdrawal of life support (WLS) in Korean intensive care units (ICUs). METHODS: This was a single-centered retrospective analysis of patients who died in the ICUs of a tertiary hospital in Korea from January to December 2012. WLS informed consents and clinical data were analyzed. RESULTS: Of 285 deaths during the study period, informed consents for WLS were obtained from 228 patients (80.0%). All WLS decisions were made by family members after the patient's loss of decision-making capacity. Decisions were made most frequently by the patient's son (50.6%). Patients in the WLS group were older than those in the non-WLS group, and older age was associated with the WLS decision. Thirty-seven patients (16.2%) died within one hour of WLS approval, and 182 patients (79.8%) died on the day of WLS approval. The most frequently withheld life support modality was chest compression (100%), followed by defibrillation (95.9%) and pacemaker insertion (63.3%). CONCLUSIONS: Aggressive and invasive life support measures were those most frequently withheld or withdrawn by decision-makers in Korean ICUs. The most common proxy was the son, rather than the spouse.

A statistical study of soldiers who visited the outpatient ciepartment of the Capital Armed Forces General Fiospital from 1987 to 1989 was performed. The results were as follows : 1. The total number of outpatients was 9969 with peak clinic visits in June(11.2%) and the lowest number of clinic visits in February(6.4% ). 2. The most frequent age was 22 years(20.7% ). Soldiers between 19 and 24 years old comprised 68.1% of total patients. 3. By rank 69.3% of the outpatients were private', 16.0% sergeant and 14,4% officers. 4. The most common dermatoses were dermatophytosis, contact dermatitis, scabies, acne, seborrheic dermatosis, urticaria, alopecia, condyloma acuminatum, verruca, folliculitis, psoriasis, insect bite reactions, pityriasis rosea, herpes zoster and corns. 5. Frequent diseases, which occured during summer season, included dermatophytosis, contact dermatitis and inser,t bites. The incidence of scabies, pityriasis prsea was increased during winter and that of psoriasis was increased during spring.

PURPOSE: To characterize the MRI appearance of the peripherally located schwannoma as compared with pathologic findings. MATERIALS AND METHODS: 11 cases of 13 lesions of the schwannoma confirmed by pathology were analyzed, retrospectively. T11 T2 and Gadolinium-enhanced T1 weighted sagittal and axial images were obtained. The signal intensity, contour of lesion, and relationship with surrounding tissue were analyzed. All cases were correlated with MRI and pathologic findings. RESULTS: In 9 out of the 11 cases, schwannoma was connected to the main nerve trunk. Among them, tumors were located centrally in 6 cases and eccentrically in 3 cases. MR findings of schwannoma were iso signal intensity on T1WI(8 cases) with muscle intensity, high signal intensity on T2WI(all cases), strong heterogenous enhancement in all cases. 8 cases showing heterogenous appearance on T2WI, showed mixture of Antoni-A and B area and multifocal hemorrhage. Central low and peripheral high signal intensity on T2Wl(Target sign) was mainly high cellular component in the central portion and diffuse myxoid degeneration at the periphery, pathologically. Reversed target appea.rance(central high, peripheral low on T2WI) revealed central cystic degeneration with low cellular component and hemorrhage in the central portion, and high cellular component at the periphery. Linear band-like low signal intensity on T2WI, suggesting capsule of the schwannoma, was not the true capsule proven by pathology. Thin true capsule was not visualized on T2WI. CONCLUSION: MR appearance of schwannoma was non-specific. The signal intensity on T2 weighted MR imaging was determined by the presence of multifocal hemorrhage, focal cystic and myxoid degeneration, admixture of Antoni-A and B area.

Complications after a median sternotomy incision, which is used currently in most open heart surgery, are serious, although it is infrequent. Reconstruction of the sternal defect resulting from dehiscence of median sternotomy is still big challenge to the most plastic surgeons. Since vascularized greater omentum was transposed to eliminate mediastinal wound problems, many vascularized regional muscle flaps became mainstay in reconstruction of median sternotomy wound. We treated 13 patients with median sternotomy dehiscence between October of 1993 and March of 1998. In two patients, the wound problems were so confined to superficial tissue that debrided and closed primarily. Eleven patients with deep wound infection were managed with vigorous debridement of all necrotic tissues and resultant defects were covered with regional muscle flaps: rectus myocutaneous flap(3) and bilateral pectoralis advancement flap(8). We used the pectoralis major advancement flaps without counter incision at humeral insertion site and the dissections were limited only medial to the anterior axillary line to preserve the axillary fold. In five patients with larger defects, we elevated muscle and cutaneous flaps separately to make these flaps more mobile. Large portion of two rectus abdominis flaps could not survive, whereas pectoralis advancement flaps had mo special wound problems. Only one patient developed fistula due to remained wire, regardless to flap surgery.

Conjoined twins are one of the rarest and most challenging congenital anomalies in pediatric surgery. Successful surgical separation is more unusual, since the majority of conjoined twins are incapable of separating successfully. The timing of separation is variable, but separation is usually delayed until such infants are relatively mature (i.e, 9-12 months of age). Operative survival was 50% in those operated on in the neonatal period, but 90% in those of over 4 months of age. Our case was early separated beacase of one of the twins having heart problems. These twins were omphalopagus and shared only simple liver bridge without vascular and biliary communications. Surgical separation was undertaken successfully on the 11th day of life, so we describe our experience with the review of the relevant literatures.
