OBJECTIVES: Insomnia is one of the major concerns in the elderly population. Cognitive behavioral treatment for insomnia is the first line treatment option, but there are some limitations including time and cost burdens and the requirement for sufficient cognitive resources to obtain a proper treatment effect. The Brief intervention for insomnia (BII) is a treatment that focuses on behavioral aspects of insomnia in primary care practices. The purpose of this study was to evaluate the effects of BII in community-dwelling older adults. METHODS: A total of 47 older adults with insomnia were enrolled from community centers between May 2016 and January 2018. They participated in the BII program for three weeks. We gathered sleep-related participant information with using the Pittsburgh sleep quality index (PSQI), the Sleep hygiene index, and a sleep diary. Clinical efficacy was evaluated by comparing total sleep time (TST), sleep latency (SL), waking after sleep onset (WASO), and sleep efficiency (SE) before and after the treatment. RESULTS: There was significant improvement in sleep-related features after BII. Global score and sleep quality from the PSQI, freshness, and WASO from the sleep diary showed statistically significant improvement. CONCLUSION: We found BII showed positive clinical efficacy in community dwelling older adults, especially from the perspective of subjective sleep quality and WASO. This finding implies that BII can be effectively applied for the managment of elderly insomnia patients in a community setting.

OBJECTIVE: We designed a nationwide study with limited exclusion criteria to investigate the prevalence of metabolic syndrome (MetS) in Korea and its relationship with antipsychotic medications. METHODS: This multicenter, cross-sectional, and observational study included patients diagnosed with schizophrenia or schizoaffective disorder. Sixteen hospitals enrolled 845 patients aged 18 to 65 years prescribed any antipsychotic medication between August 2011 and August 2013. MetS was diagnosed using the criteria of the modified Adult Treatment Panel III of the National Cholesterol Education Program with the Korean abdominal obesity definition (waist circumference ≥85 cm in women, ≥90 cm in men). RESULTS: The prevalence of MetS in all patients was 36.5% and was significantly higher in men than women (men, 40.8%; women, 32.2%) and was significantly correlated with age [odds ratio (OR) 1.02] and duration of illness (OR 1.03). The prevalence of MetS across antipsychotic drugs in the major monotherapy group was as follows: 18.8% for quetiapine, 22.0% for aripiprazole, 33.3% for both amisulpride and paliperidone, 34.0% for olanzapine, 35% for risperidone, 39.4% for haloperidol, and 44.7% for clozapine. CONCLUSION: The prevalence of MetS is very high in patients with schizophrenia or schizoaffective disorder. Screening and monitoring of MetS is also strongly recommended.

PURPOSE: This study was performed in order to determine the changes over time in preventable and potentially preventable traumatic death rates, and to assess the factors that affected the deaths of trauma patients which occurred in Korean pre-hospital and hospital settings. METHODS: All trauma deaths occurring either in the emergency department (ED) or after admission at twenty Korean hospitals between August 2009 and July 2010 were retrospectively analyzed. The deaths were initially reviewed by a team of multidisciplinary specialists and classified into non-preventable, potentially preventable, and preventable deaths. Only preventable and potentially preventable deaths were the subject of our analysis. Structured data extraction included patient demographics, vital signs, injury severity, probability of survival, preventability of mortality, reported errors in the evaluation and management of the patient, and classification of error types (system, judgment, knowledge). RESULTS: During the study period, 446 trauma victims died in the ED or within 7 days after admission. The mean age was 52 years, 74.1% were men and the mean time from injury to death was 35.6 hours. The most common cause of death was head injury (44.7%) followed by hemorrhage (30.8%) and multi-organ failure (8.0%). The rates of preventable/potentially preventable deaths were 35.2% overall and 29.8% when limited to patients surviving to admission. Of all death classifications, 31.2% were potentially preventable and 4.0% were preventable. Errors leading to preventable death occurred in the emergency department (51.2%), pre-hospital setting (30.3%) and during inter-hospital transfer (60.8%). Most errors were related to clinical management (48.4%) and structural problems in the emergency medical system (36.5%). CONCLUSION: The preventable death rates for Korean trauma victims were higher than those found in other developed countries, possibly due to poorly established emergency medical systems for trauma victims in pre-hospital and hospital settings. A system wide approach based on the emergency medical system and well-developed in-hospital trauma teams should be adopted in order to improve the quality of care of trauma victims in Korea.

Chronic obstructive pulmonary disease (COPD) is a substantially under-diagnosed disorder, and the diagnosis is usually delayed until the disease is advanced. However, the benefit of early diagnosis is not yet clear, and there are no guidelines in Korea for doing early diagnosis. This review highlights several issues regarding early diagnosis of COPD. On the basis of several lines of evidence, early diagnosis seems quite necessary and beneficial to patients. Early diagnosis can be approached by several methods, but it should be confirmed by quality-controlled spirometry. Compared with its potential benefit, the adverse effects of spirometry or pharmacotherapy appear relatively small. Although it is difficult to evaluate the benefit of early diagnosis by well-designed trials, several lines of evidence suggest that we should try to diagnose and manage patients with COPD at early stages of the disease.

Social welfare services for respiratory-disabled persons in Korea are offered based on the respiratory impairment grade, which is determined by 3 clinical parameters; dyspnea, forced expiratory volume in 1 second (FEV1), and arterial oxygen tension. This grading system has several limitations in the objective assessment of respiratory impairment. We reviewed several guidelines for the evaluation of respiratory impairment and relevant articles. Then, we discussed a new grading system with respiratory physicians. Both researchers and respiratory physicians agreed that pulmonary function tests are essential in assessing the severity of respiratory impairment, forced vital capacity (FVC), FEV1 and single breath diffusing capacity (DLco) are the primarily recommended tests. In addition, we agreed that arterial blood gas analysis should be reserved for selected patients. In conclusion, we propose a new respiratory impairment grading system utilizing a combination FVC, FEV1 and DLco scores, with more social discussion included.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major cause of chronic morbidity and mortality throughout the world and is the only major disease that is continuing to increase in both prevalence and mortality. The second Korean National Health and Nutrition Survey revealed that the prevalence of COPD in Korean subjects aged > or =45 years was 17.2% in 2001. Further surveys on the prevalence of COPD were not available until 2007. Here, we report the prevalence of spirometrically detected COPD in Korea, using data from the fourth Korean National Health and Nutrition Survey (KNHANES IV) which was conducted in 2007~2009. METHODS: Based on the Korean Statistical Office census that used nationwide stratified random sampling, 10,523 subjects aged > or =40 years underwent spirometry. Place of residence, levels of education, income, and smoking status, as well as other results from a COPD survey questionnaire were also assessed. RESULTS: The prevalence of COPD (defined as forced expiratory volume in 1 sec/forced vital capacity <0.7 in subjects aged > or =40 years) was 12.9% (men, 18.7%; women, 7.5%). In total, 96.5% of patients with COPD had mild-to-moderate disease; only 2.5% had been diagnosed by physicians, and only 1.7% had been treated. The independent risk factors for COPD were smoking, advanced age, and male gender. CONCLUSION: The prevalence of COPD was 12.9% in the KNHANES IV data. Most patients with COPD were undiagnosed and untreated. Based on these results, a strategy for early COPD intervention is warranted in high risk subjects.

OBJECTIVE: To analyse sexual assault cases epidemiologically. METHODS: We evaluated 129 female patients who visited the female sexual assault center in northeast area of Seoul with a complaint of sexual assault. After patient's consent was obtained, history taking and physical examination was performed. Photographic record was obtained on appropriate sites. We reviewed their medical and standardized rape records and photographs retrospectively. Descriptive statistics was performed with medico-legal parameters. RESULTS: Of 129 sexual assault victims, 44.2% were under 19 years of age. Spring was relatively vulnerable season for sexual assaults, vulnerable time was between 12 to 18 o'clock for victims younger than 14 years and between 0 to 6 o'clock for victims older than 13 years. Most frequent place was hotel for adolescent victims and was victim's house for other age groups. Sixty seven percent of assailants were strangers to the victims. Genital trauma was more frequent in victims younger than 20 years and alcohol use was more prevalent among adolescent victims. 82.2% of victims visited hospital within 24 hours and 91.4% of victims has destroyed potential physical evidences by bathing, douching, tooth brushing, changing clothes, defecation or urination. Follow up rates are low: 28.7% in obstetrics and gynecology clinic, 5.4% in psychiatric clinic. CONCLUSION: This study provide more accurate information about epidemiology of sexual assaults.

The purpose of this study was to examine the ultrastructural characteristic of the normal pylorus mucosa, and their structural changes induced by the ligation of common bile duct of the male rabbits weighing about 1.5 kg each. Experiment animals were divided into normal, sham operation, and experimental groups. Common bile duct ligation was performed under ether anesthesia and anjmals were sacrificed on the 1st, 3rd, 5th, 7th and 14th day after operation. The mucosal specimen of the pylorus, were fixed and embedded with common method. The sections were cut on a LKB-V ultratome, and observed under a JEM 100CX II electron microscope. The results were as follow : 1. In the early stages (1st, 3rd, 5th day groups) following the ligation, surface mucous cells have the various electron densities and shape of the mucous granules. In the late stages (7th, 14th day groups) following the ligation, many surface mucose cells containing numerous electron dense mucous granules are seen. 2. In the early stage of the ligation of bile duct, secretory function of EC cells was depressed, but in the later stage, the cells showed recovered secretory activity. 3. Secretory function of D cells was depressed on the early groups after the ligation of common bile duct, but they showed recovered secretory activity from the late groups after the ligation of the common bile duct. 4. Secretory function of G cells was activated on the early groups after the ligation of common bile duct, but they showed depressed secretory activity from the late groups after the ligation of the common bile duct. Considering the above findings, common bile duct ligation probably causes the dysfunction of the pyloric surface mucous cells that results in delayed mucous formation and secretion, and recovered mucous secretory function on the late stages. EC cells and G cells, depressed the secretory activities on the early stages and recovered on the late stages of the ligation of common bile duct. But D cells in the pyloric mucosa was activated on the early groups after the ligation of common bile duct ligation, but they was depressed secretory activities on the late groups.

BACKGROUND: This study compared the bronchodilator efficacy and safety of tiotropium inhalation capsules (18microgram once daily) with a ipratropium metered dose inhaler (2 puffs of 20microgram q.i.d.) in patients with chronic obstructive pulmonary disease (COPD). METHOD: After the initial screening assessment and a two-week run-in period, patients received either tiotropium 18microgram once daily or ipratropium 40microgram four times daily over a period of 4 weeks in a double blind, double dummy, parallel group study. The outcome measures were the lung function, the daily records of the peak expiratory flow rate (PEFR), the patients' questionnaire, and the use of concomitant salbutamol. The forced expiratory volume in one second (FEV1) and the forced vital capacity (FVC) were measured 5 minutes before inhalation, and 0.5, 1, 2 and 3 hours after inhaling the study drug on days 0, 14 and 28. RESULT: In 16 centers, 134 patients with a mean (SD) age of 66 (7) years and a predicted FEV1 of 42 (12)% were analyzed. The trough FEV1 response was significantly higher in the tiotropium group than in the ipratropium group after a four-week treatment period. The weekly mean morning PEFR of the tiotropium group was consistently higher than that of the ipratropium group during the 4-week treatment period with differences ranging from 12.52 to 13.88 l/min, which were statistically significant. Tiotropium was well tolerated by the COPD patients during the 4-week treatment period and had a similar safety profile to ipratropium. CONCLUSION: This study shows that tiotropium administrated once daily has a superior bronchodilator effect with a similar safety profile in treating COPD patients compared with ipratropium, inhaled four times daily.
