This study was conducted to find out an appropriate means for preventing the juvenile delinquency (JD), which is supposed to be greatly realted to family environment. The data were collected through a questionnaire survey with a means of writing by themself, to 257 middle and high school students and 309 juvenile delinquents who were in confinement. The questionnaire was consisted of 27 items of juvenile delinquencies, 15 questions about personal environment in their period of childhood, 36 questions on their home atmosphere, 25 items with regard to their parental behavior to their children in the rearing of them. The extent of delinquency was calculated by summing the numbers of experienced delinquencies of the listed items. The study subjects were divided into two groups; student group (SG) and juvenile delinquent group (JDG) and the collected data were analyzed with the extent of delinquency in each group by SPSS/PC+statistical package. The extent of JD was increased as the study subjects grew older, defective families were more common, total family income was more poor, parents' educational level was lower, personal expenses were higher and the conflicts between parents were more high in JDG as compared with of SG. The differences were statistically significant. As long as the extent of delinquency is concerned, delimquent points of JDG were significantly higher as compared with that of SG in all items except one item, below the primary school item in fathers' educational level. (In order to prevent JD in our country, it is recommended that educational level and the living standared of the lower class people should be raised, the sound families which do have less conflictsshould be established as much as possible, the present educational system which is making much conflicts between parents and their offsprings should be changed so that their given temperament would be brought up to the highest level, defective families should be reduced as much as possible and adults should not do actions that are considered not to be done by youngsters and must set a good example.)

The pulmonary cytology has reached a high level of accuracy. By the examination of the sputum and/or bronchial brushings, it is now possible to make a diagnosis in 70% to 90% of patients with cancer. Primary melanoma of the lung is very rare and there have been reported about 20 cases in the world literature. We present a case of primary malignant melanoma of the lung in a 61-year-old male diagnosed by cytologic examination of sputum, bronchial brushing and aspirated pleural fluid. Histologic examination of bronchoscopic biopsy and examination of the skin and other primary sites confirmed the diagnosis.

To evaluate the antihypertensive effects of serotonin antagonist, ketanserin, a daily dosage of 10~40mg (18.9+/-6.8 mean+/-SE) was administered to 22 patients with essential hypertension and aged 55??1 years (64+/-7.7 mean+/-SE) for 12 weeks. After 12 weeks of ketanserin treatment mean blood pressure decreased from 177.9+/-11.9 to 15.7+/-15.3mmHg in systole and from 104.2+/-7.4 to 88.4+/-7.9mmHg in diastole (P<0.001). There was no significant change in heart rates with ketanserin treatment. The antihypertensive treatment with ketanserin was effective in 18 patients(81.8%) and ineffective in 4 patients (18.2%). Adverse reactions such as drowsiness (8.7%), edama (4.3%) and weakness (4.3%) were noted, but all were mild and transient. This results suggest that ketanserin is an effective and safe antihypersive agent in the treatment of essential hyperension.

The diagnosis of Hodgkin's disease is based on the morphologic identification of Reed-Sternberg (RS) cells and its variants in paraffin-embedded sections. The origin of RS cells remains a subject of controversy, and cells resembling RS cells are observed in some non-Hodgkin's lymphoma of T-cell lineage. In this study, eighteen cases of Hodgkin's disease (3 nodular sclerosis, 6 diffuse lymphocyte predominance, and 9 mixed cellularity) were studied with peanut agglutinin(PNA), anti-Leu-M1(CD15), LN2(CD74), Ber-H2(CD30) and bauhinia purpurea (BPA) by the avidin-biotin-peroxidase complex(ABC) method in paraffin-embedded sections. RS cells and their variants revealed positive reactions with one or more of the reagents in all examined cases. BPA staining was positive in 17 of 18 cases (94.4%), PNA staining was positive in 9 of 18 cases (50.0%), Leu MI was positive in 7 of 18 cases(38.9%), Ber-H2 was positive in 11 of 18 cases (61.1%), and LN2 was positive in 8 of 18 cases(44.4%). The staining properties of examined markers were recognized as paranuclear, diffuse cytoplasmic and cellular membranous patterns, but LN2 disclosed diffuse cytoplasmic staining in the positive cells. BPA also showed dense cytoplasmic staining reaction with macrophage-histiocytes. BPA reactivity was not affected by fortnalin fixation or paraffm embedding. Thirty six cases of non-Hodgkin's lymphomas(IO T-cell and 26 B-cell type) were also examined. The neoplastic cells of those cases did not stain positive with BPA, PNA, and Leu-Mi, but stained positively with LN2 in 3 cases of T-cell lymphomas and 14 cases of B-cell lymphomas, and BeT-H2 in T-cell lymphomas. In conclusion, to facilitate the detection of RS cells and related variants in paraffm sectionse of Hodgkin's disease, BPA can be used as a useful marker because of its high-detection rate, reproducible staining pattem, and resistance to fixative.

Intestinal tuberculosis is an infectious disease which is still prevalent in the developing countries including Korea. It may occur insidously, have a vague clinical marofestation, and take a chronic course. We have analyzed 101 cases of intestinal tuberculosis. proven by clinical and histopathologic diagnosis for 10yrs since 1977. The results are as follows: 1) Intestinal tbc was prevalent in the age of 20-30 and the male to female ratio was 1:1.7. 2) Among clinical manifestations, abdominal pain, and tenderness, general malaise and abdominal mass were observed in order of frequency. 3) Active pulmonary lesion was associated in 73 cases (73.3%). 4) Ileocecal region was the most frequent site of involvement in barium study and in colonoscopy. 5) The most frequent colonoscopic finding was multiple ulceration and pseudopolyposis and chronic granulomatous inflammation was noted in 58% on hitopathology. 6) Ulcerative type was the most common type 45.4% by intestinal x-ray and colonofiberscopic examination

PURPOSE: We report the results of microvascular anastomosis using a microvascular anastomotic coupler (MAC) system. MATERIALS AND METHODS: Twenty cases (12 patients) of venous anastomoses performed using a coupler system were examined. The patients' age, gender, preoperative diagnosis, donor tissue, vessel diameters, size of coupler, time for anastomosis, patency rate immediately after surgery and the final survival rate of the transferred tissue were evaluated. RESULTS: The mean time for anastomosis using the coupler system was 3 min and 15 sec. The immediate patency rate after anastomosis was 100% without any leakage of blood or thrombus formation. At the final follow up, the transferred tissue survived in all cases. CONCLUSION: Microvascular anastomosis using a coupler system in orthopaedic reconstructive surgery can shorten the vascular anastomosis time and significantly reduce the total ischemic time of the transferred tissue. This system can be easily used after a short training period. This system minimizes the intimal damage of the vessel, easily overcomes the diameter discrepancy and provides secure fixation at the anastomosis site. This system can be a good strategy for substituting the conventional suture anastomosis.

Background: The number of general cosmetic practitioners impersonating dermatologists in Korea has increased, leading to serious harm that is significant enough to attract the attention of health authorities, which dermatologists are deeply concerned about. Objective: We conducted a survey targeting dermatologists to gather their opinions on the behavior, problems, and countermeasures of general cosmetic practitioners disguising themselves as dermatologists. Methods: A total of 280 dermatologists completed the survey between January and February 2024. The questions covered demographic characteristics, experiences of cosmetic general practitioners falsely introduced themselves as dermatologists, complications experienced by patients who received treatment after being mistaken for a dermatologist, the seriousness of the problem for cosmetic general practitioners impersonating dermatologists, and the relationship between the shortage of essential medical personnel and the phenomenon of cosmetic general practitioners disguising themselves as dermatologists. Results: Despite cases in which cosmetic general practitioners impersonate dermatologists, most dermatologists have not responded appropriately in many instances. Dermatologists have reported many cases of complications after receiving dermatological treatment from such cosmetic general practitioners. Most dermatologists are concerned about the serious problems of general cosmetic practitioners, disguising themselves as dermatologists and anticipating many adverse effects. Conclusion We believe that we need to pool our wisdom to solve these problems and expect that this study will provide valuable basic data for solving these problems in the dermatology and medical environments of Korea.
