Melanocytes were identified by the dopa reaction, and counted in vertical sections of 183 specimens of normal skin and 218 specimens of patients with pigmentary disorders. The incidence of dopa-positive cells in the basal layer was determined. One cell in 9 in the basal layer was dopa-positive in normal specimens. There was no significant difference in the incidence of dopa-positive cells between male and female and between adult and children. Specimens from face, neck and prepuce revealed comparatively high incidence of dopa-positive cells. Among pigmentary disorders, vitiligo and halo area of halo nevus were characterized by an abscence or marked reduction in the number of dopa-positive cells, but lentigo and cafe-au-lait spot were characterized by an increase in their number In tuberous sclerosis, tinea versicolor and idiopathic guttate hypomelanosis, there wasn't any change of the melanocyte population between lesional skin and normal skin. The significance of these findings in vertical skin sections was discussed.

BACKGROUND: There have been many articles about the chemical peeling of Caucasian skin, but there have been few reports about postpeel results among Oriental people. OBJECTIVE: The purpose of this report is to evaluate the effects of chemical skin peeling on the facial skin of Korean individuals over a two year period and compare these results with those relating to Caucasian skin. METHOD: Using 15 to 50 per cent trichloroacetic acid (TCA), we have peeled 121 pationts with fine wrinking, irregular pigmentary deposits, superficial acne scars, and melasma, and observed them for 2 years. RESULTS: In contrast to melasma, fine wrinkling and irregular pigmentary deposits responded efficiently to TCA peeling. About 70 per cent of the patients showed satisfactory clinical results one year after treatment while 50 per cent of them did so two years after treatment. Postpeel hyperpigmentation and erythema lasted for 3.15 months and 6 weeks, respectively, on average. CONCLUSION: If we select a fair-skinned woman in her fifties, even though she is an Oriental. TCA peeling can treat the fine wrinkling or irregular pigmentary deposits to a satisfactory degree.

Nevus lipomatosus cutaneous superficialis(NLCB) is a rare condition consisting of ectopic fat tissue in the dermis and having the predilection for the pelvic girdle, especially gluteal region. The patient was a 20 year-old female. About 8 years prior to the first visit she had noticed the rice-sized papules on her lower back, which had been gradually increased in size and coalesced to become two, cerebriform, skin colored to yellowish tumor masses of soft consistency, distributed on both sides of the midline of lower back, and measuring respectively 3.5X7.Qcm and 7.0x11.5cm in size. Jihe biopsy specimen taken from the tumor mass revealed the ectopic presence of fat lobules occupying half of the reticular dermis. The fat lobules consisted of almost mature fat cells with the presence of dilated capillaries in their centers.

A secondary cleft lip nasal deformity can be corrected by many procedures including central lip tissue transfer, forked flap, nasal floor and alar base advancement, nasal skin flaps and composite graft. These procedures have been applied for many years, but each one has some conspicuous residual problems. We propose triple V-Y advancement flaps, which we have performed on 13 secondary cleft lip and nasal deformity patients over the past 6 years. The W-shaped triple reverse V-shaped incision easily exposed the alar cartilages. We made the advancement and rotation of the nasal skin flap to lengthen the columella and project the nasal tip. Postoperatively, the columella length and nasolabial angle were found to be increased by an average of 3.7 mm and 42 degrees, respectively. In lateral view, a relatively natural nasal line was achieved. The scar in the nasal tip posed few problems. This procedure should be useful for the correction of the secondary cleft lip nasal deformity.

Benign symmetric lipomat,osis is a rare disease of undetermined cause characterized by symmetric deposits of adipose tissue o:n the neck, upper trunk and abdomen. We report three cases of kienign symmetric lipomatosis, one of which is associated with alcoholic liver disease and the patient complained of a diffieulties in neck motion, All of them are about sixty year old men with history of frequent alcohol consumption. In histopathologic findings, the reticular dermis was completcly replaced by mature fat cells and there was a slight increase in vascular and fibrous elements.

The inverted nipple presents many problems including both cosmetic and functional aspects and impairment in breast feeding. the histopathologic characters of inverted nipple are that inverted nipple has less fibromuscular tissue than normal nipple and has short lactiferous duct and dense fibrous tissue. Many surgical and non-surgical techniques have been designed for correction of the inverted nipple. But most of these techniques have produced unsatisfactory problems. especially undesirable recurrence is most important problem. We experienced 19 inverted nipples in 12 patients between March 1995 and January 1998. We combined modified Teimourian method, purse-string suture and Z-plasty. and had good result for 3weeks to 30months follow up. This method was effective for correction of the inverted nipple with low recurrence rate and simple techniques.

PURPOSE: This treatment planning study was undertaken to evaluate the impact of beam angle configuration of intensity-modulated radiotherapy (IMRT) on the dose of the normal liver in hepatocellular carcinoma (HCC). MATERIALS AND METHODS: The computed tomography datasets of 25 patients treated with IMRT for HCC were selected. Two IMRT plans using five beams were made in each patient; beams with equidistance of 72degrees (Plan I), and beams with a 30degrees angle of separation entering the body near the tumor (Plan II). Both plans were generated using the same constraints in each patient. Conformity index (CI), homogeneity index (HI), gamma index, mean dose of the normal liver (Dmean_NL), Dmean_NL difference between the two plans, and percentage normal liver volumes receiving at least 10, 20, and 30 Gy (V10, V20, and V30) were evaluated and compared. RESULTS: Dmean_NL, V10, and V20 were significantly better for Plan II. The Dmean_NL was significantly lower for peripheral (p = 0.001) and central tumors (p = 0.034). Dmean_NL differences between the two plans increased in proportion to gross tumor volume to normal liver volume ratios (p = 0.002). CI, HI, and gamma indices were not significantly different for the two plans. CONCLUSION: The IMRT plan based on beams with narrow separations reduced the irradiated dose of the normal liver, which would allow radiation dose escalation for HCC.

We already achieved the goal of the elimination of leprosy that was recommended by WHO. But the amazing change of our country's situation of the economical & social conditions makes the need of the migrant worker. Especially, the portion of migrant workers form India, Nepal, Indonesia, Philippines, Bangladesh, & Vietnam, the countries of relatively high prevalence rate of Hansen's disease are increasing among them recently. It means the attention about the influx of Hansen's disease form the foreign countries. We perform the survey for Hansen's disease of the migrant worker. Total 603 workers were surveyed. We found only 4 persons, that had the high titer(above 500) of the result of PGL-1 ELISA, and only 3 persons, that had some findings, the suggestive finding of Hansen's disease, of cutaneous & neurological symptoms. In spite of the special study, we did not conform the diagnosis of Hansen's disease among them. During this survey, we did not find the conformed patients of Hansen's disease. But we think that we will be concerned about the influx of Hansen's disease from foreign countries, because of the recently significance change of the epidemiological situations of Hansen's disease in Korea.

Catecholamine-induced cardiomyopathy associated with neuroblastoma is rarely reported. We report a case of catecholamine-induced cardiomyopathy associated with neuroblastoma in a 33-month-old female that was treated with extracorporeal membrane oxygenation (ECMO). She was tentatively diagnosed with acute myocarditis and presented with hypertension. Because of rapid patient deterioration despite pharmacological treatments, ECMO was applied. ECMO can be helpful in cases of catecholamine-induced cardiomyopathy associated with neuroblastoma.
