Vitiligo is an acquired, disfiguring skin disease characterized by the loss of melanin, which results in depigmented areas of the skin. It affects at least 1% of the world's population. In countries where people are dark skinned, vitiligo is a major health problem. The pathogenesis of vitiligo has not been fully elucidated, but three possible origins, autoimmune, neurohumoral and self destruction of melanocyte, have been described. The clinical manifestations of vitiligo are well described in many reports. However in Korea, a few studies on the clinical features of vitiligo have been performed. Authors studied 217 Korean cases of vitiligo who had been visited at the Department of Dermatology, Kyung Hee University Hospital during the last 1 year (1978.4.1~1979.3.31). (countinued..)

In the treatment of posterior cruciate ligament injury, posterior displacerrient of tibia might be occured because of the direction of gravity due to weight of lower leg. To prevent this problem several methods have been introduced, but not settled yet. Therfore the author tried to solve this problem by applying Quengel brace that was firstly described by Mommsen in 1922 and perfected by Jordan using the correction of flexion contracture of the knee in hemophiliacs. But owing to the development of some problems in original hinge for prevention of posterior displacement of tibia after posterior cruciate ligament injury, we modified the design of the hinge that more effective anterior traction force should be operated on tibia. The authors applied Quengel brace including original and modified hinge to 21 cases of posterior cruciate ligament injury between June 1983 and May 1986. The followings were obtained. 1. By modification of the hinge, more effective anterior traction force operated on tibia without pressure sore or joint narrowing. 2. On clinical application of modified Quengel brace, posterior displacement of tibia were prevented effectively.

Thoraic outlet syndrome is a collective term in which symptoms and signs are due to bony and soft tissue compression of the neurovascular bundle at the thoracic outlet. It is the purpose of this paper to evaluate the results of treatment of patients with thoracic outlet syndrome by surgical methods. In this study, 7 cases, comprised of cervical rib (3 cases), excessive callus formation after clavicular fracture (2 cases), and scalenus anticus syndrome (2 cases), which had developed thoracic outlet syndrome were treated at Severance Hospital and good results were obtained.

Histocytic medullary reticulosis, known as malignant histiocytosis, is a disorder characterized by a systemicproliferation of morphologically abnormal histiocytes with prominent erythrophagocytosis. Fever, wasting, lymphdenopathy, hepatosplenomegaly and pancytopenia are the main clinical pictures. Prognosis is very poor andinvariably die within several months. Authors present radiological findings of pulmonary involvement in 5 cases of histologically proven histiocytic medullary reticulosis. The findings are progressive interstitial, alveolar ormixed infiltrations, small amount of pleural effusion, hilar and/or mediastineal lymph node enlargement and cardiomegaly. Histiocytic medullary reticulosis should be borne in mind in differential diagnosis of any patientswho has unexplanable above radiological findings.

Potentially, some donor site complications are associated with the harvesting of autogenous tricortical iliac bone grafts for anterior spinal fusion. The purpose of this study was to evaluate the reliability of the anterior iliac crest reconstruction after harvesting autogenous iliac grafts for anterior spinal fusion. We devided into two groups : the study group were the anterior iliac crest reconstruction in 57 patients with minimal twelve months follow up period, the control group were not the anterior iliac crest reconstruction in 21 patients who could not obtain the rib from retroperitoneal approach. The average follow up was obtained at 43.3 months(12 to 72 months) in study group, at 41.6 months(12 to 60 months) in control group. The study group had a tendency to improve the donor site pain after incorporation of the rib graft and the control group tend to remain the donor site pain till late especially in the thinner group and combined disease group. In residual deformity of the donor site, the study group was superior to the control group. Residual deformity of the study group was associated with the complications such as displacement and resorption of the grafts. Cosmetic residual deformity tends to be higher in the thinner group. Radiographically all rib gragts incorporated in situ in 51 patients despite of some cases of migration(Average 11 weeks and 4 days) and clinical results did not affect by biological behavior of rib grafts on the follow up radiogram. The authors attempted anterior iliac crest reconstruction using the implants (Mennen plate in 3 patients, threaded pin in 3 patients) after large harvesting of autogenous tricortical graft in 6 patients who could not obtain the rib from retroperitoneal approach or could not fit the rib too the defect. In those cases the results were satisfactory clinically. These results suggest anterior iliac crest reconstruction can minimize painful deformity after the harvesting of autogenous tricortical iliac grafts for anterior spinal fusion.

Authors carried out experimental study on chemotherapy with oral administration of Dithiazanine iodide (D.I.) and Bithionol sulfoxide(B.S.) in rabbit clonorchiasis. And the following result was obtained. In change of the E.P.G (eggs per gram feces) by D.I. administration, it was rather increased in early stage of the administration than prior to administration, and thereafter decreased gradually. In the change of the C.S. worm body by D.I. administration, there was not only prominent change of supporting tissue but also the change of reproductive organ was found. In considering the wormicidal effect of D.I. from detecting rate of survival worms, the effect was slight in group of 100 mg(80 mg/kg) per day dosage, but the effects were very excellent and almost complete by proper times of administration in groups of 200 mg (130 mg/kg) per day or higher dosage. But the side effect and intoxication sign of D.I. were appearent in groups of 200 mg or higher dosage. By B.S. administration, E.P.G. was decreased gradually. In changes of the C.S. worm body by B.S. administration, prominent inhibitory chnnge was seen in egg formation ability. Slight wormicidal effect of B.S. was observed in groups of 140 mg (100 mg/kg) per day or higher dosage. Side effect and intoxication sign of B.S. were found little in groups of 140 mg or lesser dosage.

PURPOSE: It has been known for a long time that infants of insulin dependent diabetic mothers are prone to develop macrosornia, organomegaly, hyperbilirubinemia, respiratory distress syndrome, hypoglycemia, hypocalcemia, septicemia and congenital anomalies in the neonatal period. And echocardiographic asymmetrical- ventricular septal hyper- trophy(ASH) has been observed in the newborn infants of diabetic mothers. The etiology of the ASH remains unknown, although fetal hyperglycemia and subsequent glycogen deposits have been postulated as contributing factors. Therefore, we have studied whether large for gestational age(LGA) has played an important role of developing ASH. METHODS: We compared echocardiographic findings in neonates of LGA and appro- priate for gestational age(AGA), who were admitted to the Department of Pediatrics, Chung Ang University Hospital from April 1994 to March 1997. RESULTS: 1) Mean LVED in LGA and AGA were 1.96+0.06cm and 1.94+0.04cm, respectively. 2) Mean LVPW in LGA and AGA were 0.37+0.05cm and 0.370.05cm, respectively. 3) Mean IVS in LGA and AGA were 0.400.09cm and 0.380.09cm, respectively. 4) Mean IVS/ LVPW in LGA and AGA were 1.09+0.12 and 1.040.17, respectively. There was no statistical significance between two groups in echocardiographic findings. CONCLUSION: There is no relation between LGA and ASH in the neonate. According- ly, we may not need to perform echocardiography LGA routinely.
