OBJECTIVES: Sleep problems has been consistently reported as a suicidal risk factor in adults and, recently, also in adolescents. In this study, dividing study subjects by the previous suicidal behaviors (suicidal vs non-suicidal), we compared the group differences of suicidal risk factors, and examined the possibility of sleep as a suicidal risk factor. METHODS: Study subjects were 561 (271 boys and 290 girls) from a community sample of high school students. Suicidal Risk Behavior Checklist, Center for Epidemiological Study-Depression (CES-D), Symptom Checklist-90-Revision (SCL-90-R) Anxiety and Aggression subscale, Pittsburg Sleep Quality Index (PSQI) were done. RESULTS: Forty six students (8.1%) reported previous actual self-harm behavior as a suicidal attempt, 181 students (32.4%) reported having suicidal thought only. Three hundred thirty four students (59.5%) reported no previous suicidal behavior (thought and attempt, both). Suicidal behavior group showed higher score on risk behaviors such as school violence, substance use and internet addiction. CES-D, SCL-90-R, PSQI showed significant group difference. Logistic regression analysis showed suicidal risk were significantly associated with depression, stress in suicidal risk factors and sleep latency, daytime dysfunction in PSQI. Analysis of variance (ANOVA) shows the most prolonged sleep latency and increased index of all PSQI components except sleep efficiency in suicidal attempt group. CONCLUSIONS: Sleep Problems had a strong association with the suicidal risk behavior in adolescents. Sleep problems, especially, prolonged sleep latency, daytime dysfunction might be important markers for suicidal behavior. Screening for sleep problems in adolescents are encouraged for the parents, school teachers, and related medical physicians.

OBJECTIVES: The analysis of heart rate variability (HRV) is a useful non-invasive tool to investigate the autonomic nerve function. Previous studies on the relationship between HRV and depression have been reported controversial results. Similarly, the correlation between the serum lipids and depression is debatable. The purpose of this study is to examine the relationship between heart rate variability, lipid profile and depression. METHODS: A total of 42 patients with major depressive disorder (MDD) and 32 age and sex-matched normal subjects who had no previous history of major medical and mental illnesses were recruited for this study. A structured-interview was used to assess the general characteristics and psychiatric illness. HRV measures were assessed by time-domain and frequency-domain analyses. Psychological symptoms were measured using the Hamilton rating scale for anxiety (HAM-A), Hamilton rating scale for depression (HAM-D). In addition, the evaluation for lipid profile was performed by blood test. RESULTS: In serum lipid profile test, MDD group showed higher cholesterol (197.68+/-42.94 mg/dL vs. 176.85+/-34.68 mg/dL, p=0.044), TG (139.45+/-92.54 mg/dL vs. 91.4+/-65.68 mg/dL, p=0.018), LDL (130.03+/-33.18 vs. 106.62+/-27.08, p=0.004) level than normal control group. In HRV time domain analyses, the standard deviation of the NN interval (SDNN) was decreased in MDD group than normal control group, but was not significant (32.82+/-14.33 ms vs. 40.36+/-21.40ms, p=0.078). ApEn (Approximate Entrophy) was significantly increased in MDD group than normal control group (1.13+/-0.11 vs. 0.91+/-0.18, p<0.001). ApEn was correlated with LDL level (r=0.277, p=0.028), HAM-D scores (r=0.534, p<0.001) and HAM-A scores (r=0.470, p<0.001). CONCLUSION: MDD patients showed increased ApEn, one of the HRV measurement. And this ApEn was correlated with LDL, HAM-D and HAM-A scores. In this study, the analysis of ApEn would be a useful test of MDD.

There are various reports referring to the clinical siignificances and removal of postgastrectomy bezoar. In this case, suture thread were thought to he the important factor of the bezoar formation, This bezoar was removed intaetly uaing fiber-optic endoscope in patinet who had postgastrectomy bezoar, by cutting the thread by biopsy forceps.

OBJECTIVES: This study was aimed to examine the prevalence of neuroleptic-induced irregular menstruation and its related factors as well as the possible relationship of irregular menstruation with psychopathology and extrapyramidal symptoms in schizophrenic patients. METHODS: Thirty five schizophrenic inpatients at Naju National Mental Hospital who satisfied the diagnostic criteria of DSM-IV were selected. They had drug-free periods for more than 1 month before admission and had been taking neuroleptics for more than 3 months after admission. From all patients, reliable information regarding the sociodemographic characteristics, the menstrual histories before and after admission and clinical characteristics, including previous and current medications were investigated. The following were also evaluated: Serum prolactin level(by radioimmunoassay), psychopathology(by positive and negative syndrome scale: PANSS), and extrapyramidal symptoms(by extrapyramidal symptom rating scale: ESRS). RESULTS: Twelve patients(34%) showed regular menstruation and 23 patients(66%) were suffering from irregular menstruation. Of those with irregular menstruation, 13 patients(37%) had oligomenorrhea and 10 patients(29%) had amenorrhea. There were no differences in sociodemographic characteristics and menstrual histories before admission between the regular and irregular menstruation groups. But, the significant differences between the two were found in the following variables: The irregular menstruation group had shorter durations of illness, higher daily doses of current neuroleptics, higher serum prolactin levels, higher scores on the general psychopathology scale of PANSS, and higher scores on the parkinsonian symptom scale, hypokinetic symptom factor and clinical global impression of ESRS. CONCLUSION: The high prevalence of the irregular menstruation in schizophrenic patients reflects a state of hyperprolactinemia due to the interference of dopamine activity by high doses of neuroleptics.

In order to assess the efficiency of Percoll gradient centrifugation(PGC) as a method of sperm selection, we have examined morphological characteristics of spermatozoa from 40 teratozoospermic patients attending the Infertility Clinic of Inchon Gil Gerneral Hospital. Patients were divided into three groups according to percentage normal morphology in the fresh sample : group A(n=5), < 5% normal morphology : group B(n=21), 5~14% normal morphology : and group C(n=14), > 14% normal morphology. Morphology slides were perpared using Diff-Quik staining techniques and evaulated by Kruger strict criteria, under oil immersion at a magnification of X 1000, specific defects, head, neck and tail were assesed individualy. The results were as follows. 1. Following PGC, sperm samples with enhanced morphology were recovered for all groups. 2. For group A, PGC did not select a sample with significantly improved morphological characteristics. 3. Usually, sperm defects affected by PGC was head and neck. No significant difference was found for tail abnormality. In conclusion, Percoll gradient centrifugation is an efficient sperm preparation technique when the semen sample exhibits teratozoospermia, especially head or neck abnormality. However, in sample with < 5% normal form or tail abnormality, There is not significant improvement following PGC.
