Sleep Wake Patterns and Nocturnal Sleep Parameters in the Morning and Evening Types / 신경정신의학

OBJECTIVES: The aim of our study was to compare sleep wake patterns and nocturnal sleep parameters between the morning type (MT) and evening type (ET). METHODS: The Morningness-Eveningness Questionnaire, Pittsburgh Sleep Quality Index (PSQI), and Korean version of the Epworth Sleepiness Scale (KESS) were administered to subjects recruited among visitors to the Chuncheon National Museum from 2010 to 2011. Actigraphy data (Actiwatch-2, Philips-Respironics Co.) were collected from eight MT (Age 38.0+/-3.8, M : F=2 : 6), 12 neither type (NT) (Age 34.2+/-5.1, M : F=2 : 10), and nine ET (Age 30.3+/-6.8, M : F=2 : 7) subjects. RESULTS: Scores for PSQI and KESS did not differ significantly among the MT, NT, and ET groups. No differences in time in bed, total sleep time, sleep efficiency, wake after sleep onset, sleep latency, and fragmentation index were observed among the three groups. In the ET group, the mean wake time on free days was significantly later, and the mean sleep duration on free days was significantly longer, compared with those of the MT group (p<0.01). CONCLUSION: No differences in sleep quality, daytime sleepiness, and nocturnal sleep parameters were observed among the MT, NT, and ET groups. Compared to MT subjects, ET subjects showed later wake time and longer sleep duration on free days.

Primary Repair of a Huge Incisional Hernia by Using an External Oblique Myofascial Releasing Technique without Mesh: A Case Report

Incisional hernias are one of the most common complications after abdominal surgery and are an important cause of postoperative morbidity. Various methods are available for repairing incisional hernias, such as primary suture repair, an open mesh technique, and a laparoscopic mesh technique. The surgical management of a large incisional hernia by using a prosthetic mesh in a contaminated operative field (i.e., opened bowel from previous stoma or bowel resection) remains a difficult challenge because the non-absorbable mesh used is accompanied by a potential risk of infection and its related morbidity. We present a case of a large abdominal-wall defect, which was corrected by utilizing an external oblique myofascial releasing technique without the use of mesh, in a patient with an incisional hernia coexistent with Hartmann's colostomy.

A case of Malignant Mixed Mullerian Tumor of the ovary / 대한산부인과학회지

Malignant mixed Mullerian tumor of the ovary is extremely rare. This is heterologous neoplasms which apparently arise from undifferentiated mullerian stroma and is composed of mixture of malignant epithelial and stromal elements. We report a case of malignant mixed mullerian tumor of the ovary with brief literature review.

A case of Huge Isolated Retroperitoneal Leiomyoma / 대한산부인과학회지

Primary retroperitoneal neoplasms are rare, accounting for only 0.1-0.2% of all malignancies. Retroperitoneal location of leiomyoma are uncommon. Less than 2% of retroperitoneal tumors are leiomyomas. We report a case of huge retroperitonal leiomyoma mimicking solid adnexal mass with brief literature review.

A case of low grade endometrial stromal sarcoma / 대한산부인과학회잡지

Uterine sarcoma is a rare female neoplasm that accounts for about 2-4% of all uterine malignancies. According to the classification of Norris and Taylor, the subgroup of endometrial stromal sarcoma (ESS), comprising approximately 7-15% of all uterine sarcomas, can be divided into low-grade ESS and high-grade ESS and is characterized by proliferations composed of cells with endometrial stromal cell differentiation. We experienced this infrequent malignant tumor in a 52-year old woman and was treated by total abdominal hysterectomy with bilateral salpingo-oophorectomy followed by adriamycin chemotherapy. We present a case of low-grade ESS with a brief review of the literature.

Epidemiologic Characteristics of the Pneumoconiosis Patients in Manufacturing Industries / 한국역학회지

Pneumoconiosis was the first reported occupational disease in Korea and was the most common one until 1990. In the past, most pneumoconiosis patients were found among underground workers in various mines. Recently this occupational disease has increasingly affected workers in manufacturing industries such as ship building, briquette, glass, foundry industries, and so on. In order to investigate the scale of pneumoconiosis in manufacturing industries, we evaluated the detailed medical examination records and insurance deliberation data from 1989 until 1994. Information about work history, medical history, and exposure dust type were collected for each member of the study population. All chest X-rays were interpreted and classified using the International Labor Organization(ILO) scale by three radiologist who have had extensive experience evaluation pneumoconiosis. For the calculation of the incidence rate of manufacturing pneumoconiosis, we analyzed the Specific Health Examination data and estimated the population at risk as a denominator of the incidence rate. We divided manufacturing industry into 9 subclasses by industrial classification and estimated the incidence rate of pneumoconiosis per 100,000 workers at risk respectively. The results were as follows, 1. 485 workers were newly diagnosed with pneumoconiosis during 6 years from 1989 to 1994. 482 workers had radiographs consistent with simple pneumoconiosis and three with progressive massive fibrosis. Among those with radiographs consistent with simple pneumoconiosis, 395 workers(81.4%) had category 1 profusion, 76 workers(15.7%) had category 2 profusion and 11 workers(2.3%) had category 3 profusion. 2. Almost all of them were male(97.9%) and their average age was 48.3 uears. Manufacturing pneumoconiosis patients were more common in their forties and fifties. 3. The average duration of dust exposure required for the occurrence of pneumoconiosis was 13.5 years. In the case of metal products manufacturing which is mostly related to welding, the average duration of dust exposure was 12.0 years. It was slightly shorter than other manufacturing industries. The average duration of dust exposure required for the occurrence of pneumoconiosis seemed to be shorter in welding operators, even though the welders lung has a weak tissue reaction and the condition is reversible. 4. According to the Industrial classification, 299 cases(61.6%) were found in workers of non-metal mineral products manufacturing, and 56 cases(11.5%) in basic metals industry. 5. The average annual incidence rate of pneumoconiosis in manufacturing industries from 1990 to 1994 was 56.6 per 100,000 workers at risk. On sub-classification, the average annual incidence rate of pneumoconiosis in non-metal mineral products manufacturing industry was the highest among them, showing 479 per 100,000 workers at risk. 6. Radiologic prevalence rate of tuberculosis in these cases was 6.6%. 7. X-ray category profusion in newly diagnosed manufacturing pneumoconiosis varied according to sub-classification. The proportion of category 1 profusion in metal products manufacturing is higher than that in non-metal mineral products manufacturing. 8. The type pattern of small round opacities varied according to sub-classification in manufacturing industry. In non-metal mineral products manufacturing, the small round opacity were observed 25.9% cases with p type, 72.1% with q type and 2.0% with r type respectively. But in metal products manufacturing, the small round opacity were observed 51.4% cases with p type and 48.6% with q type respectively. The cause might be that the exposed dust is different according to job. 9. The type pattern of small round opacities varied according to dust type. Metal dusts showed similar radiologic shape to the coal dusts, but welding fume showed more frequent p type(60.3%) and less frequent q type(377%). rock dust showed less frequent p types(18.3%) and more frequent q types(75.3%). Since the incidence rate of non-metal manufacturing workers showed higher rate than other manufacturing industry, Preventive measures and health care education should be carefully carried out in these workers.

A Cross-Sectional Study on Smoking and Tuberculosis Prevalence in Korea / 한국역학회지

In Korea, National Tuberculosis Prevalence surveys have been regularly carried out in every 5 years since 1965 and the 7th one was done on March 27-June 10, 1995. In this 7th survey, three variables related to smoking(smoking experience, number of cigarettes the smokers consume a day, and the age they started smoking) were included in the survey form. This study is a result of an analysis of data on smoking and tuberculosis prevalence for males aged 20 and over to see how the smoking is associated with tuberculosis prevalence of the Korean adult males. It was found that the smoking prevalence of Korean adult males aged 20 and over was 60.8% and the tuberculosis prevalence of Korean adult males was 2.2%. In univariate analysis, tuberculosis prevalence was higher among current and ex-smokers(2.4%) than non-smokers(2.0%), eventhough the difference was not statistically significant. However, in multivariate stratification analysis controlling for age and living place, smoking variables were significantly or marginally associated with tuberculosis prevalence in some strata.
