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.

BACKGROUND: Early detection and treatment of cytomegalovirus (CMV) infection is very important because CMN infection is a major cause of morbidity and mortality after organ transplantation. CMV antigenemia assay has been reported to be very sensitive and specific for detection of CMV infection among many laboratory methods. However, there is no single method correlated well with the infection state up to now. We compared the results of SHARP Signal System Assay (Digene, USA) using PCR and hybridization with those of CMV antigenemia assay (Clonab CMV-kit; Biotest AG, Germany) to evaluate their clinical usefulness. METHODS: We performed SHARP Signal Assay on whole blood samples of 125 from 56 transplanted patients submitted for CMV antigenemia at Samsung Medical Center. We compared the results with those of CMV antigenemia and evaluated the correlation with CMV disease state. RESULTS: Fifty six patients were classified as three groups; 43 patients with no evidence of CMV infection, four patients with CMV infection and 9 patients with CMV disease. Twenty four cases (19.2%) showed discrepant results between the two methods. Of the 22 cases showing positive only by SHARP Signal Assay, two cases were proved to be CMV disease, 12 cases were on antiviral treatment and remaining cases had no evidence of infection. Two cases showing positive only by CMV antigenemia were confirmed to be CMV disease. For CMV disease, the sensitivity of SHARP Signal Assay and CMV antigenemia were 85.7% and 90.5%, respectively and the specificity of them were 73.1% and 93.3%, respectively. CONCLUSIONS: CMV antigenemia is thought to be useful for early diagnosis and follow-up of antiviral treatment as a quantitative and highly specific method, and SHARP Signal Assay can be used as a complementary method because it correlates well with disease state.

Background: The absence of effective antiviral medications and vaccines increased the focus on non-pharmaceutical preventive behaviors for mitigating against the coronavirus disease 2019 (COVID-19) pandemic. To examine the current status of non-pharmaceutical preventive behaviors practiced during the COVID-19 outbreak and factors affecting behavioral activities, we compared to the 2015 Middle East respiratory syndrome coronavirus (MERS-CoV) outbreak in Korea. Methods: This was a serial cross-sectional population-based study in Korea with four surveys conducted on June 2 and 25, 2015 (MERS-CoV surveys), and February 4, and April 2, 2020 (COVID-19 surveys). Of 25,711 participants selected using random digit dialing numbers, 4,011 participants (aged ≥ 18 years) were successfully interviewed, for the 2020 COVID-19 (n = 2,002) and 2015 MERS-CoV (n = 2,009) epidemics were included. Participants were selected post-stratification by sex, age, and province. The total number of weighted cases in this survey equaled the total number of unweighted cases at the national level. We measured the levels of preventive behaviors (social distancing [avoiding physical contact with others]), and practicing transmission-reducing behaviors such as wearing face mask and handwashing. Results: Between the surveys, respondents who reported practicing social distancing increased from 41.9%–58.2% (MERS-CoV) to 83.4%–92.3% (COVID-19). The response rate for the four surveys ranged between 13.7% and 17.7%. Practicing transmission-reducing behaviors (wearing face masks and handwashing) at least once during COVID-19 (78.8%, 80.2%) also increased compared to that during MERS-CoV (15.5%, 60.3%). The higher affective risk perception groups were more likely to practice transmission-reducing measures (adjusted odds ratio, 3.24–4.81; 95 confidence interval, 1.76–6.96) during both COVID-19 and MERS-CoV. Conclusion The study findings suggest markedly increased proportions of non-pharmaceutical behavioral practices evenly across all subgroups during the two different novel virus outbreaks in Korea. Strategic interventions are needed to attempt based on preventive behavior works.

We report a case of primary cutaneous mucinous adenocarcinotna in a 64-year-old female. The tumor was about 2cm in size, forminga round dome-shaped alopecic scalp mass which had gradually increased in size over about 5 years, Histalogic examination revealed that the tumor was divided into numerous compartments by strands of fibrous tissue. In each compartment, abundant amounts of pale-staining mucin surrounded nests or cords of moderately anaplastic epithelial cells. We couldn't find any evidence of internal neoplasms as a source of metastasis. We resected the tumor with approximately a 1 cm margin and then performed a split thickness skin graft.

Localized fibrous tumor is an uncommon submesothelial origin tumor found in pleura most commonly. Sixty five-year-old man with right lower quadrant pain was admitted. He was treated with resection of tumor and was diagnosed as localized fibrous tumor of pelvic cavity. He is now being followed up without any evidence of recurrence for 34 months. This case is presented with reviewing references.

PURPOSE:Ghrelin is an endogenous ligand of the growth hormone secretagogue receptor, and stomach is the major site of ghrelin secretion. The purpose of this study is to compare the serum ghrelin concentrations between patients with type 2 diabetes mellitus (DM) and normal adults. We studied also whether serum ghrelin levels in the patients with type 2 DM are correlated with body mass index (BMI), serum insulin, lipid profiles, and creatinine levels. METHODS:Forty patients with type 2 DM and forty normal adults were included in this study. We measured heights and weights of the subjects and calculated their BMIs. Blood samples were obtained to measure the ghrelin concentration and their sera were stored at -20degreeC until used. In all subjects, serum ghrelin levels were measured using the commercially available Ghrelin(human) EIA kit. RESULTS:No differences of mean values were detected between the control group and the type 2 diabetic group for age, body weight, BMI, and the levels of serum total cholesterol, triglyceride, HDL cholesterol, and creatinine. But ghrelin level of the type 2 diabetic group (71.1+/-30.5 ng/L) was significantly lower than the control group (139.7+/-36.9 ng/L). In the control group, the ghrelin level showed positive correlation with HDL cholesterol (Pearson's correlation coefficient=0.37, P<0.05). In the diabetic group, the ghrelin level showed weakly positive correlation with insulin concentration. However, there was no significant relationship between serum ghrelin and various parameters in the diabetic patients group. CONCLUSION: In this study, ghrelin concentration in type 2 diabetic patients was lower than that in the control group. In the control group, serum ghrelin concentrations were positively correlated with HDL cholesterol. In the type 2 diabetic group, there was no significant correlation between insulin and ghrelin concentrations.

Calvarium protects the brain, the most important organ. The defect of calvarium results in not only deformity but also fatal injury from the trauma. The cranial bone defects result from 1) removal of bone flap for intracranial decompression or infection 2) fracture 3) excision of tumor 4) craniectomy for craniosynostosis. The goals of cranioplasty are to protect the brain from trauma and make the aesthetically acceptable contour. From 1990 to 1995, we experienced twelve cases of cranioplasty using autogenous bone graft; 5 cases with rib bone, 3 cases with iliac bone, 2 cases with calvarial bone, and 2 cases with rib and calvarial bones. The result was very excellent without any significant complications.
