This study aims to explore the impact of distributional changes in coronavirus disease 2019 (COVID-19) infection fear with sex differences. A quota sampling strategy was followed and 483 Korean adults were surveyed in a community sample. Self-report questionnaires were used to assess COVID-19 infection fear, depressive symptoms, and general characteristics.Quantile regression was used to explore the regression relationship of COVID-19 infection fear and an individual’s sex. There was a significant difference in COVID-19 infection fear (P= 0.001) and depression (P = 0.008) between the sexes - male and female. The differences between sexes at the 20th and 30th percentiles were significant (β = 2.04, P = 0.006; β = 1.5, P = 0.004, respectively). The results demonstrate that sex significantly predicts COVID-19 infection fear and women had significantly greater fear than men in the mild-level of COVID-19 infection fear.

BACKGROUND: Most of adult patients with chronic immune thrombocytopenic purpura (ITP) that was refractory or relapsed to high-dose corticosteroid have been treated with splenectomy as a 2nd line treatment. However, these patients may have increased morbidity and mortality according to the operation and the increased risk of infection for a lifetime after splenectomy. Despite of the above risks, 30~40% of these patients can't maintain remission. Furthermore, the remission rate after splenectomy is relatively lower in patients with corticosteroid-refractory chronic ITP than that in those patients with corticosteroid-responsiveness. We studied whether danazol, an attenuated androgen, is useful or safe as 2nd line treatment for chronic ITP instead of splenectomy and which factors are associated with the response to danazol. METHODS: Among the patients with chronic ITP who failed corticosteroid therapy in our hospital, 28 patients who received danazol as the 2nd line treatment were analyzed retrospectively. A complete response was defined that the platelet count was increased to 150 x 10(3)/microL, and a partial response was defined that the platelet count was increased above 50 x 10(3)/microL or there was an increased platelet count of more than 20 x 10(3)/microL from the pre-treatment platelet count when the platelet count was above 50 x 10(3)/microL at the time of danazol therapy. RESULTS: The median age of patients was 44 years (range: 19~67) and the number of male patients was 9 (32.1%) and the number of females was 19 (67.9%). The starting daily doses of danazol were variable from 200 to 600mg, though most of the patients were treated with 400mg daily (18 cases, 64.3%). The median duration of danazol therapy was 201.5 days (range: 13~973) and the median duration from ITP diagnosis to danazol treatment was 56 days (range: 20~2,430). Among the accrued 28 patients, 22 patients showed a response to danazol (78.5%); there were 6 patients (21.4%) with a complete response and 16 patients (57.1%) with a partial response. The median duration from danazol treatment to response was 30 days (range: 0~180). The median response duration of danazol treatment was 330 days (95% CI: 182~478) by the Kaplan-Meiyer method. For the danazol-responsive patients, 9 patients (40.9%) remained in remission and 13 patients (59.1%) relapsed. Grade 3~4 toxicity was observed in two patients and three patients stopped danazol because of adverse effects. Hepatotoxicity was the most common toxicity. CONCLUSION: Our findings suggest that danazol is a beneficial, safe choice as the 2nd line treatment for patients with chronic ITP that was refractory or relapsed to corticosteroid.

An internal hernia is a rare disease that causes bowel obstruction. It is difficult to diagnose because the symptoms and the signs are the same as those for other obstructive diseases of the bowel. Early diagnosis and management are essential, and early surgical management may reduce complications such as ischemia, and strangulation. We experienced two cases of internal hernias. One patient underwent a laparotomy, and had a transmesenteric defect with a herniated and strangulated small bowel segment. The other patient underwent a laparoscopic surgery, and we found that the left broad ligament had a focal defect with a herniated small bowel segment. An internal hernia is an uncommon disease, and its differentiation from other obstructive diseases of the bowel is difficult. However, the clinician should consider that the internal hernia might be the cause of the bowel obstruction, especially in patient with no previous history of intra- abdominal surgery. Early diagnosis can improve the clinical outcome through early surgery.

Objective: To investigate the health-related quality of life (HRQOL) related to hyperthermic intraperitoneal chemotherapy (HIPEC) following primary or interval cytoreductive surgery for primary ovarian cancer. Methods: Between 2010 and 2016, a total of 184 patients were randomly assigned to receive cytoreductive surgery with HIPEC (n=92) or without HIPEC (n=92). Quality of life (QOL) assessment was evaluated at baseline (before surgery); on postoperative day 7; after the 3rd and 6th cycle of adjuvant chemotherapy; and at 3, 6, 9, and 12 months after randomization. Patient-reported QOL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) core questionnaire (EORTC-QLQ-C30), ovarian cancer questionnaire modules (QLQ-OV28), and the MD Anderson Symptoms Inventory (MDASI). Results: Of the 184 patients enrolled, 165 (83/92 in the HIPEC group and 82/92 in the control group) participated in the baseline QOL assessment. There were no statistically significant differences in functional scales and symptom scales in QLQ-C30; symptom scales, including gastrointestinal symptoms QLQ-OV28; and severity and impact score in MDASI between the 2 treatment groups until 12 months after randomization. Conclusion HIPEC with cytoreductive surgery showed no statistically significant difference in HRQOL outcomes. Thus, implementation of HIPEC during either primary or interval cytoreductive surgery does not impair HRQOL.

OBJECTIVE: The primary goals of the present study were to assess intellectual function in participants with schizophrenia or bipolar disorder (BD) and to investigate the relationships between cognitive decline and the severity of each type of psychopathology. METHODS: The present study included 51 patients with schizophrenia and 42 with BD who were recruited from the psychiatry outpatient clinic of Jeju University Hospital between March 2011 and March 2014. The Korean Wechsler Adult Intelligence Scale (K-WAIS) was administered to each of the 93 participants, and they were categorized into two groups based on their current intelligence quotient (IQ) and their estimated premorbid IQ: severely impaired group (SIG) and mildly impaired group (MIG). The Minnesota Multiple Personality Inventory (MMPI) and the Brief Psychiatric Rating Scale (BPRS) were used to assess psychopathology. RESULTS: The SIG schizophrenia participants exhibited significantly higher scores on the frequent (F) and schizophrenia (Sc) subscales of the MMPI, but significantly lower scores on the correction (K) and psychopathic deviate (Pd) subscales compared with the MIG schizophrenia participants. Furthermore, the BPRS scores were significantly higher in the SIG schizophrenia participants relative to the MIG schizophrenia participants. The SIG BD participants had significantly higher F, masculinity-femininity (Mf), paranoia (Pa), and Sc but significantly lower Pd scores compared with the MIG BD participants. CONCLUSION: The present findings revealed a significant discrepancy between the estimated premorbid levels of cognitive function and current cognitive function in participants with schizophrenia or BD. Moreover, this discrepancy was correlated with severity of psychopathology in both groups.

OBJECTIVE: The purpose of this study was to evaluate the occurrence of the suicidal ideation and associated factors with self-reported suicidal ideation within the last 12 months among Korean high school students. METHODS: A total of 697 adolescents were recruited from high schools (age range: 15-16 years) in Jeju area. According to existence of suicidal ideation, they were divided into two groups-suicidal ideation group and non-suicidal ideation group, and the differences between groups in terms of various sociodemographic and clinical characteristics, including depression (Beck Depression Inventory), and health related conditions. RESULTS: A total of 187 (26.8%) high school students reported suicidal ideation, and the rate of suicidal attempt was 4.9% (n=34). The associated factors of suicidal ideation were depression [odds ratio (OR)=2.42, p< or =0.001], short sleep duration (OR=1.84, p=0.009), current alcohol use (OR=4.94, p< or =0.001), self reported poor health (OR=2.10, p=0.004), and school bullying (OR=3.06, p=0.002). CONCLUSION: These results may have important implications for the strategies and specified intervention in preventing suicidal ideation in Korean high school students.

OBJECTIVE: This study evaluated the occurrence and associated factors with self-reported suicidal ideation within the last 12 months among Korean elementary school students. METHODS: In a school-based cross-sectional survey, a total of 657 students were recruited from elementary schools (age range: 11??2 years) in Jeju area. They filled out self-completing questionnaires on suicidality (suicidal ideation and suicidal attempt), depression (Kovacs' Children's Depression Inventory), and sociodemographic characteristics, including school and family factors. RESULTS: A total of 192 (29.2%) students reported suicidal ideation, and the rate of suicidal attempt was 6.1% (n=40). Logistic regression analysis identified factors associated with recent suicidal ideation. Female had higher rates of suicidal ideation than male [odds ratio (OR)=1.81, p=0.005], and students with depression (OR=3.23, p<0.001) and experience of abuse in the home (OR=6.77, p<0.001) were at high risk for suicidal ideation. CONCLUSION: These results suggest that suicidal ideation and actions are relatively common in Korean elementary school students, and have implications for prevention and intervention.

PURPOSE: This study was conducted to describe the trends and age-period-cohort effects on the incidence and mortality rate of cervical cancer in Korea. MATERIALS AND METHODS: The incidence and mortality rate of cervical cancer among ≥ 20-year-old women from 1993 to 2012 were obtained from the Korea Central Cancer Registry and the Korean Statistical Information Service. Age-standardized rates were calculated and Joinpoint regression was used to evaluate the trends in the incidence and mortality rate. Age-period-cohort analysis was performed to investigate the independent effects of age, period and cohort. RESULTS: The incidence of cervical cancer decreased from 32.8 per 100,000 in 1993 to 15.9 per 100,000 in 2012 (annual percent change [APC], –3.9%; 95% confidence interval [CI], –4.2% to –3.6%). The mortality rate decreased from 5.2 per 100,000 in 1993 to 2.1 per 100,000 in 2012 (APC, –4.8%; 95% CI, –5.1% to –4.4%); however, the incidence and mortality rates among young women (< 30 years old) increased. An age-period-cohort model of the incidence and mortality rate showed decreasing period effects between 1993 and 2008 and decreasing cohort effects between 1928 and 1973, while birth cohorts after 1973 exhibited slight increases in the incidence and mortality rate of cervical cancer. CONCLUSION: Recent decreases in the incidence and mortality rate of cervical cancer were due to decreases in the period and cohort effects, which reflect the implementation of a cancer screening program and changes in lifestyle. However, our findings also highlighted an increase in cohort effects on the incidence and mortality rate among young women born after 1973.
