We examined epidemiologic study of 6,072 patients who visited Wonkwang Neuropsychiatric hospital since July 11 of 1986 until July 10 of 1991 and compared this results with previous study(Park et al 1986). The study revealed as follows:1. Of total patients males visited this hosptial more than females as 57.1%, Most of them(84.0%) resided Iri and neighbouring Iri. In the point of insurance, insured patients, medicaid patients and uninsured patients were 57.1%, 21.8% and 21.1% respectively. On the distribution of age, the twenties, the thirties were 24.6%, 22.8% respectively and twenties and thirties were about half of total patients. 2. Of outpatients neurotic disorder was the most as 46.0%, secondly mood disorder and thirdly convulsive disorder, but of inpatients schizophrenia was the most as 30.5%, secondly organic mental disorder and thirdly mood disorder. 3. Of males neurotic disorder was the most as 23.4%, secondly schizophrenia, and thirdly organic mental disorder, but of females neurotic disorder was the most as 39.9%, secondly mood disorder and thirdly schizophrenia. alcoholic mental disorder(94.6%), organic mental disorder, child mental disorder were mostly found in males,but mood disorder(64.5%) and neurotic disorder were mostly found in females. 4. On the distribution of age neurotic disorder was found the most in the thirties(25.3%), next in the twenties and in the forties, and schizophrenia was found the most in the twenties(40.5%), next in the thirties and in the forties, but mood disorder was found the most in the twenties, next in the thirties and in the forties but revealed similar rates relatively. 5. On the distribution of age of onset neurotic disorder developed nearly half during the twrnties and the thirties, schizophrenia developed mostly during the twenties (51.3%), secondly the teens and thirdly the thirties, but mood disorder developed firstly the twenties(30.7%), secondly the thirties and thirdly the fifties. on the average age of onset of illness neurotic disorder, mood disorder and schizophrenia were 32.7 years, 36.1 years and 23.6 years respectively. 6. On the duration of illness more than two years was 28.3% in neurotic disorder, 68.5% in schizophrenia and 3.9% in mood disorder and on the average duration of illness schizophrenia, mood disorder and neurotic disorder were 73.2 months, 45.5 months and 29.5 months respectively.

Running title: Cases of anesthesia for extremely low birth weight infant. Extremely low birth weight infants (birth weight < 1000 g) are prone to various morbidities such as respiratory distress syndrome, intraventricular hemorrhage, periventricular leukomalacia, patent ductus arteriosus, necrotizing enterocolitis and retinopathy. To accomplish successful anesthetic management, many precautions must be continuously taken during the operation. First, inspired oxygen concentration should be adjusted to avoid oxygen toxicity. Second, body temperature must be maintained adequately. Third, hemodynamic parameters should be kept stable. We report 2 cases of successful anesthetic management for extremely low birth weight infant who underwent ligation of patent ductus arteriosus at the neonatal intensive care unit.

저자들은 56세 여성 환자의 왼쪽 쇄골 하 정맥에 시행한 이식형 약제주입기 카테터의 삽입 후 발생한 비정상 위치에 대한 증례를 보고하고자 한다. 카테터의 끝은 환자의 늘 어진 가슴, 체위, 신체의 움직임, 카테터의 유동성 등의 영향으로 천자된 정맥 내에서 견인되고 뒤쪽으로 이동하였다. 환자는 어떠한 증상도 호소하지 않았지만 비정상 위치의 카테터는 심각한 합병증을 유발할 수 있기 때문에 제거되었다. 따라서 시술자는 약제주입기 삽입 전에 환자의 신체 상태와 단순 흉부 촬영상을 확인하고 카테터의 비정상 위치가 발생할 수 있는 위험 징후를 알아차려야 하겠다.

Fabry disease(FD) is an X-linked recessive lysosomal disorder caused by a deficiency of a-galactosidase A(a-Gal A), localized at Xq22. Besides onset of pain and paresthesias in the extremities, FD was diagnosed by absence of a-Gal A activity. In this experiment the a-Gal A activity of Korean FD patients was spectrometrically analysed using an artificial substate, 4-Mrthylumbellifery1-a-D-galactoside. As expected, no a-Gal A activity was detected in lymphocytes and lymphoblastoid cells from FD patients. To screen the mutation in their a-Gal A genes, we performed single strand conformation polymorphism(SSCP) and PCR-direct sequencing form seven a-Gal A exons. The nonsense mutation was identified both in classically affected hemyzygotes and a heterozygote. They showed the C to T transition at nucleotide number 11,002, resulting in a arginine-to-stop(R342X). This result will be applicable for pre- and neonatal detection of FD and to define the genotype/phenotype correlation.

<P>PURPOSE: To overcome the problem of organ motion in intensity-modulated radiation therapy (IMRT), gated IMRT is often used for the treatment of lung cancer. In this study, the authors investigated the accuracy of the delivered monitor units (MUs) from each segment during gated IMRT using a two-dimensional detector array for user-specific verification purpose. METHODS: The authors planned a 6 MV photon, seven-port step-and-shoot lung IMRT delivery. The respiration signals for gated IMRT delivery were obtained from the one-dimensional moving phantom using the real-time position management (RPM) system (Varian Medical Systems, Palo Alto, CA). The beams were delivered using a Clinac iX (Varian Medical Systems, Palo Alto, CA) with the Millennium 120 MLC. The MatriXX (IBA Dosimetry GmbH, Germany) was validated through consistency and reproducibility tests as well as comparison with measurements from a Farmer-type ion chamber. The authors delivered beams with varying dose rates and duty cycles and analyzed the MatriXX data to evaluate MU delivery accuracy. RESULTS: There was quite good agreement between the planned segment MUs and the MUs computed from the MatriXX within +/- 2% error. The beam-on times computed from the MatriXX data were almost identical for all cases, and they matched well with the RPM beam-on and beam-off signals. A slight difference was observed between them, but it was less than 40 ms. The gated IMRT delivery demonstrated an MU delivery accuracy that was equivalent to ungated IMRT, and the delivered MUs with a gating signal agreed with the planned MUs within +/- 0.5 MU regardless of dose rate and duty cycle. CONCLUSIONS: The authors can conclude that gated IMRT is able to deliver an accurate dose to a patient during a procedure. The authors believe that the methodology and results can be transferred to other vendors' devices, particularly those that do not provide MLC log data for a verification purpose.</P>

<P><B>Summary</B></P> <P><B>Background</B></P> <P>Adjuvant chemotherapy after surgery improves survival of patients with stage II–III, resectable gastric cancer. However, the overall survival benefit observed after adjuvant chemotherapy is moderate, suggesting that not all patients with resectable gastric cancer treated with adjuvant chemotherapy benefit from it. We aimed to develop and validate a predictive test for adjuvant chemotherapy response in patients with resectable, stage II–III gastric cancer.</P> <P><B>Methods</B></P> <P>In this multi-cohort, retrospective study, we developed through a multi-step strategy a predictive test consisting of two rule-based classifier algorithms with predictive value for adjuvant chemotherapy response and prognosis. Exploratory bioinformatics analyses identified biologically relevant candidate genes in gastric cancer transcriptome datasets. In the discovery analysis, a four-gene, real-time RT-PCR assay was developed and analytically validated in formalin-fixed, paraffin-embedded (FFPE) tumour tissues from an internal cohort of 307 patients with stage II–III gastric cancer treated at the Yonsei Cancer Center with D2 gastrectomy plus adjuvant fluorouracil-based chemotherapy (n=193) or surgery alone (n=114). The same internal cohort was used to evaluate the prognostic and chemotherapy response predictive value of the single patient classifier genes using associations with 5-year overall survival. The results were validated with a subset (n=625) of FFPE tumour samples from an independent cohort of patients treated in the CLASSIC trial (NCT00411229), who received D2 gastrectomy plus capecitabine and oxaliplatin chemotherapy (n=323) or surgery alone (n=302). The primary endpoint was 5-year overall survival.</P> <P><B>Findings</B></P> <P>We identified four classifier genes related to relevant gastric cancer features (<I>GZMB, WARS, SFRP4</I>, and <I>CDX1</I>) that formed the single patient classifier assay. In the validation cohort, the prognostic single patient classifier (based on the expression of <I>GZMB, WARS</I>, and <I>SFRP4</I>) identified 79 (13%) of 625 patients as low risk, 296 (47%) as intermediate risk, and 250 (40%) as high risk, and 5-year overall survival for these groups was 83·2% (95% CI 75·2–92·0), 74·8% (69·9–80·1), and 66·0% (60·1–72·4), respectively (p=0·012). The predictive single patient classifier (based on the expression of <I>GZMB, WARS</I>, and <I>CDX1</I>) assigned 281 (45%) of 625 patients in the validation cohort to the chemotherapy-benefit group and 344 (55%) to the no-benefit group. In the predicted chemotherapy-benefit group, 5-year overall survival was significantly improved in those patients who had received adjuvant chemotherapy after surgery compared with those who received surgery only (80% [95% CI 73·5–87·1] <I>vs</I> 64·5% [56·8–73·3]; univariate hazard ratio 0·47 [95% CI 0·30–0·75], p=0·0015), whereas no such improvement in 5-year overall survival was observed in the no-benefit group (72·9% [66·5–79·9] in patients who received chemotherapy plus surgery <I>vs</I> 72·5% [65·8–79·9] in patients who only had surgery; 0·93 [0·62–1·38], p=0·71). The predictive single patient classifier groups (chemotherapy benefit <I>vs</I> no-benefit) could predict adjuvant chemotherapy benefit in terms of 5-year overall survival in the validation cohort (p<SUB>interaction</SUB>=0·036 in univariate analysis). Similar results were obtained in the internal evaluation cohort.</P> <P><B>Interpretation</B></P> <P>The single patient classifiers validated in this study provide clinically important prognostic information independent of standard risk-stratification methods and predicted chemotherapy
