We investigated the actual status of antipsychotics maintenance therapy(AMT) for schizophrenic patients through a mail survey sent to psychiatrists practicing in Seoul and Kyonggj province who had no less than two years of psychiatric expertise and who were below fifty years of age. Out of 453 questionnaires sent, 215 completed questionnaires were returned (response rate 47%). The majority of respondents considered pharmacotherapy as the most important longterm treatment strategy for schizophrenia. Haloperidol was selected by the majority as their first choice neuroleptics. The proposed mean daily maintenance dosage was 383+/-229(75-1250)mg in chlorpromazine equivalent. The mean duration of AMT was 1.8+/-1.0(0.25-7.5)years after the first episode and 3.6+/-1.8(0.5-10)years after multi-episodes. Psychotherapy was regarded as more important by the resident psychiatrists group than by the certified psychiatrists. There were preferential differences for a particular treatment strategy, dosage and duration of AMT among the different clinics. A great number of respondents(93%) regarded long-term continuous maintenance as their major AMT policy, Only a few respondents(4.3%) were satisfied with the established guidelines for AMT in treatment of schizophrenia. The results show considerable variations in psychiatrists opinions on AMT which was influenced by grades of expertise of the clinician and the working environment of the clinic or the hospital. To decrease these variabilities and make clinically useful guidelines, it will be necessary' to do further pharmacoepidemiological studies as well as other types of related clinical research.

OBJECTIVE: This is a prospective clinical study on survivors of the collapse accident of a major department store building occurred in Seoul in lune 1995 to investigate the incidence of acute PTSD, to identify risk factors affecting the severity of PTSD symptoms, and to evaluate the pattern of symptom changes over time. METHOD: Thirty-two victims were interviewed with modified Korean version of the PTSD-I(DSM-III-R) to determine the severity of symptoms and diagnosis of PTSD. Degrees of anxiety and depression were measured with Hamilton's Anxiety Scale(HAS) and Depression Scales(HDS) respectively. Subjects were assessed in series at one month(time point 1) and three month(time point 2) from the time the accident occurred. RESULTS: The incidence of PTSD in the subjects over the 3 months was 41% using by full criteria and 48% by partial criteria. Regression analysis at the time point 1, the HDS score, which was partially related with death of accompanied persons(friends/relatives/colleagues), contributed significantly to the PTSD-I variances. At the time point 2, loss of consciousness contributed significantly to the variance of the PTSD-1, HDS and HAS scores. Between tire point 1 and time point 2, the overall severity of PTSD symptoms far all the subjects has remained almost unchanged. However, re-experience and hyperarousal symptoms were improved in comparison with avoidance symptoms, although not statistically significant. CONCLUSIONS: This study result show a high risk of developing PTSD and partial PTSD among the building collapse victims. The death of accompanied person, severity of depression and loss of consciousness are all regarded as major factors affecting the severity of PTSD. Of PTSD symptom clusters, avoidance symptoms are likely to be less changeable than reexperience and hyperarousal symptoms over time.

Systemic lupus erythematosus(SLE) is an autoimmune disease involving many organs. Mesenteric vasculitis is one of the serious organ involvement in this disease. Mesenteric vasculitis may produce mucosal ulceration, bowel edema with paralytic ileus, hemorrhagic ileitis, intussusception, perforation and mesenteric infarction. Because of high mortality rate, early diagnosis and treatment of this manifestation is very important. We experienced a case of SLE with extensive smell bowel infarction due to mesenteric vasculitis. She was 29 years old. She was suffered frem severe abdominal pain for three days. Abdominal computed tomography showed diffusse wall thickening of the small intestinal wall. After high dose intravenous steroid, her abdominal symptoms were improved. She was discharged with low dose oral steroid(15mg/day) treatment. Seven months later, she presented with sudden abdominal pain. Intravenous methylprednisolon(2mg/Kg) was started. Three days later, her abdominal symptoms were not subsided. On the plain radiograph of the abdomen, marked ileus was demonstrated. Mesenteric angiography showed diffuse decreased small bowel vascularity. A provisional diagnosis of small bowel infarction and obstruction, we performed exploratory laparotomy. She undergone small bowel segmental resection. The diagnosis was small bowel infaction due to mesenteric vasculitis.

Malignant melanoma is a malignant neoplasm originated from melanocyte. Primary malignant melanoma of the esophagus is a very rare disease comprising 0.1% of all primary neoplasms of the esophagus. As with other primary mucosal malignant melanoma, primary malignant melanoma of the esophagus has poor prognosis because of the tendency to present as an advanced neoplasm with aggressive biological behavior. We present an operated case of primary malignant melanoma of the esophagus confirmed by the adjacent squamous mucosa contained junctional nests of tumor cells showing focal pagetoid spread consistent with melanoma in situ, with a clinicopoathological review of the literatures.

OBJECTIVE: This study was done to investigate the genetic polymorphism of Aldehyde Dehydrogenase (ALDH) II and Tryptophan Hydroxylase (TPH) and examine effects of socio-demographic, psychological and genetic factors on the alcohol use in freshmen of a university in Korea. METHODS: ALDH II (N=534) and TPH (N=504) genotypes of 551 subjects were analyzed using polymerase chain reaction and restriction fragment length polymorphism method. The severity of alcohol drinking was assessed by average alcohol use per drinking episode and frequency of drinking per month. Characteristics of alcohol related behaviors, socio-demographic information, and motives and expectancies of drinking in the subjects, were assessed by designed questionnaires and selfreport scales. RESULTS: The frequencies of NN, ND, and DD genotype of ALDH II (N=534) were 64.0%, 30.1%, and 5.8%, while those of AA, AC, and CC genotypes of TPH (N=504) were 31.7%, 48.4%, 19.8% respectively. The distribution of ALDH II genotypes was not correlated with that of TPH genotypes. Subjects with D (-) (NN) genotype showed more average alcohol use per drinking episode (chi2 trend=29.42, p=0.001) and higher severity index of alcohol drinking (F=9.36, df=2, p=0.000) compared with those with D (+) (ND or DD) genotypes. Subjects with D (-) genotype showed higher frequency of heavy drinking behavior (chi2 trend=5.25, p=0.022) and blackout episode (chi2 trend=17.84, p=0.001). Socio-demographic, psychological, and genetic factors seemed to contribute to the severity of alcohol drinking in the subjects. CONCLUSIONS: C allele of TPH genotypes is important in determining the severity of drinking in subjects with NN genotype of ALDH II. Social motive, gender, and D allele of ALDH II genotype are contributing factors to determine the severity of drinking in total subjects. D allele of ALDH II genotypes plays an important role in determining the severity and motives of drinking, and other alcoholrelated behaviors.

OBJECTS:We investigated a possible association between the polymorphic trinucleotide repeat(TNR) expansion in neuronal potassium channel gene KCNN3 and schizophrenia. METHODS: CAG/CTG repeat distribution in KCNN3, CTG18.1 and ERDA1 was examined and the copy number of ligation product in repeat expansion detection(RED) was measured in Korean patients with schizophrenia(n=245) and ethnically matched healthy controls(n=116). RESULTS: Longer alleles in the KCNN3 gene were over-represented in patients. The frequency of alleles with CAG repeats longer than 19 copy in the KCNN3 gene was higher in the patients with schizophrenia as compared to controls(73.3% vs. 65.1%;p=0.029, Fisher's exact test). And this difference was more prominent in schizophrenic patients with familial background(p=0.03, Fisher's exact test). We found no difference in the frequency of longer alleles between negative and positive subtypes of schizophrenia. Ligation product size in RED and alleles with CAG repeat number in the CTG18.1 gene was not increased in the patients. The copy number of ligation product in RED was highly correlated with CAG/CTG copies of ERDA1 in the patient group(r=0.45, p<0.001) as well as in the control group(r=0.44, p<0.001). However, CAG repeat length in the KCNN3 gene was not correlated with ERDA1 score. CONCLUSIONS: Our results support the hypothesis that the longer allele of KCNN3 may be considered as a candidate gene for schizophrenia, especially in the case with familial background. And the RED assay results was affected by the CAG copy number of ERDA1.

PURPOSE: To determine the incidence of asymptomatic bacteriuria in Korean preschool children, we performed national survey. MATERIALS AND METHODS: We surveyed kindergardens in seven representative cities of Korea. Before performing urine culture, we selected children by urine dipstick screening method(leukocyte esterase and nitrite test). And we analysed the incidence according to sex, age and socioeconomic status. RESULTS: Total registered population was 2,239 children and male to female ratio was 1.16. Overall, asymptomatic bacteriuria was found in 1.03%(23 children). In the male the incidence was 0.3%(3 children) and in the female it was 2.0%(19 children). Less than 4 years old children showed higher incidence (2.9%) than those of any other age groups, such as, 0.5% in 4, 1.1% in 5 and 1.3% in 6 years old. High, middle and low socioeconomic status groups showed the incidence as 0%, 0.9% and 1.4%, respectively The number of leukocyte esterase positive children was 184(8.2%) and that of nitrite positive children was 115(5.1%). Among them urine culture was performed in 175children and 23 children showed significant bacteriuria(colony count> 100,000/ml), so predictability of asymptomatic bacteriuria by dipstick test was 13.1% Radiologic study was performed in 9 children who had bacteriuria, but none of them showed urological abnormalities. CONCLUSIONS: From the above data, we found that asymptomatic bacteriuria is more common in female, younger age and lower socioeconomic status among the Korean preschool children. Considering cost-benefit aspects of the screening for asymptomatic bacteriuria, however, we should re-evaluate the necessity of our study on these particular age groups.
