BACKGROUND AND OBJECTIVES: As previously reported, unstable angina is usually related to characteristic coronary artery lesion's morphology analyzed by coronary angiogram. This takes the form of an eccentrically placed convex stenosis with a narrow neck due to one or more overhanging edges or irregular, scalloped borders, or both. Although most studies were done for lesions with high degree stenosis(>50%), recent studies emphasized the role of vulnerability of plaque in acute coronary syndrome and even mild degree stenotic lesions may progress rapidly to evoke acute coronary syndrome. Therefore in this study, we analyzed the morphological characteristics of coronary artery lesions with mild degree stenosis as well as severe stenosis. MATERIALS AND METHODS: We conducted a retrospective study of 96 patients with angina pectoris (42 of stable patients and 54 of unstable patients) who underwent coronary angiography. Each lesions with 25% or greater diameter stenosis were categorized into simple and complex lesion(convex intraluminal obstruction with a narrow neck or irregular borders, diffuse irregularities, ulceration, thrombus). Calcification of coronary artery, extents of lesions were analyzed and stenosis grade and location were categorized by AHA classification. RESULTS: There were no significant differences between the stable angina and unstable angina in risk factors and vessel involvement, numbers of lesions, calcification and total obstruction. In morphologic analysis, complex lesions were more frequent in unstable angina than stable angina (49% vs 33%, p<0.05). The mean of percent diameter stenosis was not signigicantly different between two groups, but severe stenotic lesions with 90% or more stenosis were more frequent in unstable angina (34% vs 22%, p<0.05). Locations of involved vessels were similar between the angina groups. Complex lesions were distributed more frequent in RCA and simple lesions were more in LAD and LCX (p<0.05). CONCLUSIONS: The lesions with both complex morphology and severe degree stenosis are closely implicated in unstable angina.

Craniofacial clefts are rare among facial anomalies with an incidence of 1.5 to 5 per 100,000 births, and 1 per 100 cases of cleft lip and palate. The Tessier No. 7 clefts are unusual lesions that result from failure of the embryonic mandibular and maxillary processes to properly fuse and form the corners of the mouth. We experienced a case of Tessier No. 7 craniofacial cleft in a 1 day-old female patient who presented with a macrostomia and auricular malformation. The diagnosis was established by clinical and radiographic findings. A brief review of literature was made.

A localized area of alopecia of the scalp can be a challenge in diagnosis. We report two patients with alopecia which was found to be associated with underlying congenital melanocytic nevus. Congenital melanocytic nevus should be taken into consideration in the differential diagnosis of alopecic plaques of the scalp.

From January 1995 to December 1997, a total of 219 cases pelviscopic surgery was performed at Il Sin Christian Hospital. To evaluate the safty and efficacy of pelviscopic surgery, we reviewed indication of operation, mean age, parity, history of abdominal operation, type of operation, duration of hospitalization and complication retrospectively. The number of pelviscopic surgery have risen from 33 cases in 1995 to 53 cases in 1996 and 133 cases in 1997. The most common indications were 118 cases for ectopic pregnancy (53.9%) and 42 cases for ovarian cyst (19.2%), 20 cases for infertility (9.1%) in order. Among the ovarian cyst, endometrioma was the most common. The mean age of patients was 31+/-6.7 years old and mean parity was 0.77. In most cases, mean blood loss was lesser than 100 cc except 500 cc in LAVH, 150 cc in CISH, 106.7 cc in ectopic mass removal. The postoperative hospital stay was varied from 0 day to 10 days, but usually 2 days. The 26 cases had complicated and the most common complication was fever above 38degrees C. In conclusion, it is evident that pelviscopic surgery is lesser invasive technique, has lower complication rate and shorter the length of hospitalization. So, we expect the number and indication of pelviscopic surgery will be increased in future.

This study was aimed to explore the relationship between the type of family system and the self-concept of kidney-transplantation recipients. 190 recipients were sampled from 3 general hospitals in Seoul and Kunggi-area, KOREA. Family Cohesion and Adaptability Evaluation Scale III (Olson et al., 1985) of the Circumplex Model (Olson et al., 1983) and Self-concept Test (Jeong, Won Sik, 1968) were used to collect the data. The data collected was analyses by the t-Test and ANOVA. It was found that there were no differences on recipients' self-concepts by types of family systems. But there were differences in recipients' self-concepts by family cohesion and adaptability levels. That is, the higher level of cohesion and adaptability, the higher the recipients' self-concepts. The type of family system and recipients' self-concept are related. So the recipients and the family of recipients must be included in subjects of medical and nursing care.

Annular erythema associated with lupus erythematosus/ Sjogrens syndrome has recently been described in Orientals. We present a patient with recurrent annular erythema who partially demonstrated features of lupus erythematosus. A 32-year-old man was referred to us for recurrent annular erythema. Laboratory findings revealed mild leukopenia and the presence of antinuclear antibodies at a titer of 320 with a finely speckled pattern on Hep-2 substrates. Anti-Ro/La antibodies were also detected. A skin biopsy specimen revealed the findings of perivascular and periappendageal lymphocytic infiltration without prominent hydropic degeneration of the basal layer. Skin lesions subsided with hydroxychloroquine (400-200mg/day).
