Conventional high-dose antipsychotics tend to result in more side effects, negative symptoms and dysphoria, and at the same time lower the cognitive function which is already impaired in most schizophrenics. Florid psychotic symptoms, negative symptoms and cognitive impairment greatly impede psychosocial performance and eventual reintegration int society. The reduction of symptom and the improvement of cognitive funtions and social skills are therefore central to the psychiatric rehabilitation process. The purpose of this study was to evaluate the dose-reduction effects of antipsychotics more than 1,500mg equivalent of chlorpromazine. Fifty-one chronic schizophrenics who maintained high-does antipsychotics for more than three months were randomly assigned to two groups : 20 patients comprised the dose-maintaining group and 31 patients made the dose-reduction group. Over a sixteen weekperiod Positive and Negative Syndrome Scale(PANSS), Extrapyramidal Symptom(EPS), Nurses' Observation Scale for Inpatient Evaluation(NOSIE-30), Continuous Performance Test(CPT), Quality of Life(QOL), and haloperidol/reduced haloperidol blood levels were determined at the base line and after 2, 4, 6, 8, 12, 16 weeks to evaluate the dose reduction effects of high-dose antipsychotics. The results were as follows: 1) Dose-reduction is highly effective in reducing positive and negative symptoms, and general psychopathology. Effects were most prominent at 8, 12, 16 weeks. Among the dose reduction group, positive symptoms in positive symptom group and negative symptoms in negative symptom group were more reduced. 2) Extrapyramidal symptoms showed no significant difference between two groups. But EPS was reduced time after time within two groups. 3) Hit rates of Continuous Performance Test, which indicate attentional capacity, increased significantly after dose reduction. 4) Haloperidol and reduced haloperidol blood levels decreased until the 4th week, after which they were constant. 5) Total scores of Nurses' Observation Scale for Inpatient Evaluation were unchanged between the two groups. But among the indices, social interest and personal neatness were improved in the dose-reduction group and retardation was aggrevated in the dose-maintaining group. 6) Total quality of life scores were unchanged between two groups. But in the dose maintaining group, satisfaction scores of attention, autonomy, and interpersonal relationship decreased progressively. These findings suggest that the dose reduction of antipsychotics for chronic schizophrenics on programs of high-dose antipsychotics were effective. Dose reduction should therefore be implemanted to spread the rehabilitation and improve quality of life for chronic schizophrenics.

PURPOSE: To evaluate the role of bile duct obstuction in the development of atrophy of the liver, using ananimal model. MATERIALS AND METHODS: Seven rabbits were divided into two groups : group 1(n=5), in which therewas selective bile duct ligation, and group 2(n=2), which underwent a sham operation. Each group was evaluated using CT for changes in hepatic volume after selective bile duct ligation or a sham operation. In group I, the diameter of dilated bile duct was measured 2, 4, 8, 12 and 16 weeks after bile duct ligation, while gross andhistologic change were evaluated in all cases. RESULTS: In group 1, bile duct dilatation was seen on CT two weeks after selective bile duct ligation, and did not change significantly during follow-up. In four of five cases, CT revealed no evidence of significant atrophy of the involved segment. Pathologic specimens, however, revealed dilatation of the bile duct, periductal fibrosis, infiltration of chronic inflammatory cells, and periportalfibrosis. One of five cases showed segmental liver atrophy after selective bile duct ligation. In addion to the above pathologic findings, there was obstruction of the portal vein by foreign body reaction. In group 2, no evidence of dilated bile duct or liver atrophy was revealed by CT or pathologic specimen after a sham operation. CONCLUSION: During long-term follow-up of 16 weeks, obstruction of the bile duct did not play a major role in the development of lobar atrophy in the rabbit.

The majority of lung cancers associated with hyperamylasemia are adenocarcinomas. Here we report an unusual case of a 54-year-old male patient who complained of dyspnea, anterior chest wall discomfort and facial edema for one month, presenting with a huge mediastinal mass and hyperamylasemia complicated by pericardial effusion Histological evaluation of mediastinal mass revealed small cell carcinoma and pericardium showed nonspecific inflammation with fibrosis. The serum amylase had an electrophoretic mobility similar to that of salivary gland enzyme. There were no evidence of a salivary or pancreatic causes of hyperamylasemia. After chemotherapy, parenchymal lung lesions improved and hyperamylasemia disappeared. For the mannagement of peracardial effusion a pericardial window was forms(i. We concluded that the striking increase in serum amylase was due to the ectopic production of this enzyme by the tumor.

Acute urinary retention in aseptic meningitis is rarely encountered, and the diagnosis of aseptic meningitis may be less than straightforward, because its symptoms and neurological signs are occasionally mild or absent. We report a case in which acute urinary retention provided an appropriate indication for the diagnosis of aseptic meningitis as the cause of an undiagnosed fever.

PURPOSE: To evaluate the CT and US features of the colonic villous tumors. MATERIALS AND METHODS: We retrospectively reviewed the CT findings of 11 cases with histologically proved colonic villous tumor. CT parameters evaluated were morphological appearances and enhancing pattern (size, shape, margin, presence or absence of fronds, bowel wall thickening). CT features of six cases with malignant change were compared with five tumors without malignant change. US features available in 10 patients were also analyzed. RESULTS: On CT, thetumors showed irregular margin(n=9), presence of fronds(n=6), lobulated shape(n=11), with pericolonic invasion(n=1). Six cases with malignant change were larger(mean, 6.8cm in diameter) than those without malignant change(mean, 3.3 cm). US features in 10 cases were intraluminal mass(n=5), colonic wall thickening(n=5), with variable echogenicity. CONCLUSIONS: Colonic villous tumor appeared as a nonspecific mass on CT and US with adifficulty in distinguishing from colon carcinoma.

The angiotensin-converting enzyme (ACE) gene DD homozygote has been suggested to be a significant risk factor for the progression of diabetic nephropathy. We analyzed clinical parameters and ACE genotype distribution between type 2 diabetic patients at the extremes of renal risk, i.e. an end-stage renal failure (ESRF) group (n = 103, group 1) who were on dialysis therapy due to progression of diabetic nephropathy, and a no progression group (n = 88, group 2) who had maintained normal renal function and normoalbuminuria for more than 15 years. There were no significant differences in age, sex, body mass index, HbA1c level, or lipid profiles between the two groups (p > 0.05). Group 1 had a significantly higher prevalence of hypertension [group 1: 82.5% (85/103) vs. group 2: 50.0% (44/88), p < 0.05] and diabetic retinopathy [group 1: 103/103 (100%) vs. group 2: 28/88 (31.8%), p < 0.05] than group 2. Daily urinary albumin excretion was also higher in group 1 than in group 2 [group 1: 2873 +/- 2176 mg/day vs. 12 +/- 7 g/day, p < 0.05]. The frequencies of the DD, ID, and II genotypes of the ACE gene in group 1 and group 2 were 26.2%, 47.6%, and 26.2%, and 7.9%, 57.9%, and 34.2%, respectively. The ACE genotype frequencies between the two groups were significantly different according to a chi-square test with Bonferroni's correction (p = 0.004). The presence of the DD genotype increased the risk of ESRF 4.286-fold compared to the II genotype [odds ratio 4.286, 95% CI 1.60- 11.42, p = 0.005]. The frequency of the D-allele was higher in both male and female patients in group 1 compared to group 2, but reached statistical significance only in males [male, group 1: 50.8% vs. group 2: 35.0%, p = 0.018, female, group 1: 48.8% vs. group 2: 39.5%, p = 0.231]. This study, although limited by sample size, showed that type 2 diabetic ESRF patients more frequently expressed the DD genotype. These findings may substantiate the previously noted relationship between the ACE DD genotype and the progression of diabetic nephropathy in Korean type 2 diabetic patients.

PURPOSE: To evaluate whether the presence of a peripheral echogenic rim surrounding internal low echogenicityis helpful in the diagnosis of atypical hepatic hemangioma. MATERIALS AND METHODS: Within a two-year period, aretrospective review of the sonographic appearances of 24 atypical hemangiomas in 21 patients was performed. Diagnosis was made by dynamic and delayed enhanced CT, MR imaging or clinical follow up for one year, including follow-up sonogram. The sonographic appearances of these hemangiomas were analyzed for pattern and thickness ofthe echogenic rim, internal echo pattern, shape, and size. Additionally, forty six lesions of hepatoma, metastasis, abscess and intrahepatic cholangiocarcinoma confirmed by pathology within the same period were also evaluated for the presence of echogenic rim. RESULTS: Twenty-three of 24 lesions showed an echogenic rim ; these were thick in nine cases, and thin in 14 cases. The thickness of the rim was either uniform(n=10) or eccentric(n=13). The average maximum diameter of atypical hemangioma was 4.4cm (range of diameters, 1.5-12cm). The internal echo pattern was partially or entirely hypoechoic in 15 lesions, homogeneously isoechoic in three, and mixed insix cases. Twenty-one lesions were round, and the shape of three was irregular. The other forty six masses including hepatocellular carcinoma, metastases, cholangiocarcinoma and hepatic abscesses did not show an echogenicrim. CONCLUSIONS: The presence of a sonographic echogenic rim in a hepatic mass may help in the diagnosis ofhepatic hemangioma.
