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.

Two cases of malignant histiocytosis, in which skin involvement was a prominent finding at initial clinical presentation, are reported. 1nteresting histopathologic findings, including Langerhans granule in one case and numerous eosinophils in another, were observed. In one case remission was achieved with BACOP chemotherapy (Bleomycin, Adriamycin, Cyclophosphamide, Vincristine, and Prednisone). In the other case, the patient died nine months after the onset of the disease without any treatment.

There are many factors affecting surgical results of cervical spondylotic myelopathy. Age, duration of symptom, neurologic status, and direction of surgical approach are side to have prognostic implications. Also a high signal intensity on T2 weighted magnetic resonance imaging(HSI on T2WI) is insisted as a poor prognostic factor. We analyzed these factors in 56 patients treated over a 10-year period retrospectively. Statistical analysis was done using chi square, Mantel-Haenszel. Cochran-Mantel-Haenszel, Wilcoxon, and logistic procedure. We preferred anterior decompression when compressive lesions existed ventrally. However posterior decompression was performed in a 4 or more level stenosis. Age ranged from 22 to 74 year(mean : 50.8). 25 patients underwent the anterior procedure, 33 patients the posterior procedure, and 2 both procedures. Neurologic status was graded both preoperatively and at follow-up using the Nurick grading system from 1 to 5. The preoperative Nurick grade was 2.75+/-0.16(mean+/-SE). Mean follow-up period was 13.8 months(SE 0.14). The follow-up Nurick grade was 2.125+/-0.14, and these was noted an improvement of 0.63+/-0.12. The amount of improvement was equivalent between the anterior and the posterior approaches(0.52 vs. 0.73 respectively, p=0.67). There was no mortality. Uni- and multivariant analysis demonstrated that age, duration of symtom and HSI on T2WI had no significant effect on either follow-up Nurick grade or amount of improvement, but the preoperative Nurick grade had a significant effect(p<0.000). Comparable results can be obtained with either approaches if chosen properly. Only the preoperative Nurick grade has the prognostic value.

The main purpose of this study was to characterize and classify families of KT recipients and to identify family adaptability and cohesion, as family function, by the Circumplex model. A Cross-sectional survey approach was employed for this research project. The data was collected by the questionnaire method in 3 general hospitals in Seoul and Kyonggi-do, Korea. The Family Adaptability and Cohesion Evaluation Scales III was used. By Convenient sampling, a total of 190 subjects (Male 117, Female 73) with an average age of 39.7 years (range: 18-62 yrs.) participated. The mean age at transplantation was 36.8 yrs. (SD: 9.4 yrs.). On an average, the patients had received transplants 39.9 months previously. The data was analyzed by percentage of frequency, t-test, and one-way ANOVA by the SPSS program. The results were as follows: 1. The mean family adaptability score was 30.26(SD: 6.6, range: 12-49) and the mean family cohesion score was 34.96(SD: 6.5, range: 15-48). 2. All of 16 distinct types of family system were identified. Among them, 'Flexibly connected types' (32 families, 16.8%) were the most common and 'chaotically disengaged types' (2 families, 1.1%) were the least common. 3. Dividing the 16 unit typology into 3 basic groups of types, 'Balanced types' composed 88 families (46.3%), 'Mid-range types' composed 76 families (40.0%), and 'extreme types' composed 26 families (13.7%). 4. The family adaptation differed according to age, education level, marital status, the diagnostic age of CRF, and level of recipient's perception of the family's importance. The family cohesion differed according to age, employment status, number of kid, and level of recipient's perception of the family's importance. In conclusion, by providing nursing intervention designed to increase family adaptability and cohesion, considering the socio-demographic factors of recipient and family, nurses may improve the recipient's family function and health, and also the recipient's health and quality of life.

Empyema thoracis following pneumonia, intra-abdominal pathology, trauma, and surgical procedure continues to be a source of major morbidity and mortality. Thirty seven adult and eleven pediatric patients with empyema thoracis were treated at the University of Yeungnam Medical Center from May 1983 to November 1986. Age distribution ranged from 6 months to 72 years and showed a double-peaked curve with the highest incidence between 36 and 65 years and below 15 years of age. There were male predominance in patients above 16 years of age. The most common predisposing factors was impaired consciousness due to either alcoholism or head injury. The causes of empyema were as follows: pneumonia 64.6%, ling abscess 6.4%, intraabdominal pathology 6.4%, and surgical procedure 6.4%. The cardinal symptoms were fever, cough, chest pain, dyspnea, sputum, weight loss, anorexia, and night sweat in orders. Culture of empyema fluid were positive in 50% of patients. The isolated organisms were Gram-negative bacilli 33.3%, staphylococcus aureus 25%, and streptococcus 25%. The patients received antibiotics in conjunction with various invasive procedures: chest tube drainage 77.1%, decortications 6.3%, and repeated thoracentesis 10.3%. There were 4 deaths, 1 child and 3 adults, with an overall mortality of 8.3%.
