Small bowel malignancy consists 1~2% of overall gastrointestinal tract cancer and leiomyosarcomas of small intestine are 10~20% of small bowel malignancy. Small bowel leiomyosarcomas are rare in incidence and have no specific symptoms, signs or definite radiologic findings, so it is not easy to diagnose at early stage of disease. They are found occasionally by unknown origined gastrointestinal bleeding, abdominal pain, intestinal obstruction, perforation and palpable mass, and diagnosed mostly by operation. Recently annual case reports are increasing trend in Korea. We experienced two cases of small bowel leiomyosarcomas which was diagnosed finally by pathologic findings, so we report them with literatural review.

Malignant tumor is found in 1-2% of ovarian benign cystic teratomas. Among these malignant neoplasms, squamous cell carcinoma is by far the most common malignancy, whereas the incidence of struma ovarii is less than 5% in mature teratoma. As far as concerned the struma ovarii, a very small percentage is associated with carcinoid, mucinous or serous cystadenoma, or Brenner tumor. However, any reports of struma ovarii associated with squamous cell carcinoma in the same ovary could not be found in English literature. Recently we have experienced a case of squamous cell carcinoma and struma ovarii arising in an ovarian benign cystic teratoma in 72 year old female patient.

Background: Some epidemiological studies have indicated that weather and air pollution can cause adverse health conditions and that these effects can exhibit regional variation. The prevalence of headache is so high and it is a common cause of morbidity. Therefore, this study evaluated whether weather and air pollution were associated with the prevalence of headaches. Methods: A symmetric bidirectional case-crossover design was applied, using conditional logistic regression models to determine the association between headaches and weather and air pollution. From January 2006 to August 2007, a total of 245 patients with headaches were recruited. Headache subtypes were classifi ed as migraine, tension-type headaches, and others. Meteorological data (average temperature and relative humidity) and values related to air pollutants (CO, NO2 , O3 , SO2 , and particulate matter with an aerodynamic diameter of less than 10 μm) were obtained. Results: Higher average temperatures were associated with the total number of headaches (hazard ratio 1.124-1.130; P<0.001). With regard to headache subtype, O3 seems to provoke headaches, especially those related to tension and those listed as other headache varieties. Conversely, other pollutants, especially CO and SO2 , showed the opposite association. Conclusions: These fi ndings indicated that temperature and some air pollutants are able to affect headaches, suggesting that weather and air pollution levels seem to have an effect on the risk of headache.

Phytobezoar is rare disease in the stomach and small bowel of the patient without underlying previous gastroenterologic pathology. Because it usually occurs secondarily to peptic ulcer surgery, poor mastication, diabetes mellitus, hypothyroidism and connetive tissue disease. In morden medicine, phytobezoars found in the stomach and/or intestines in humans, are known to be associated with considerable morbidity and even mortality. Patients with gastric bezoar present with chronic postprandial epigastic pain, nausea, and vomitihg. It is diagnosed by endoscopic examination or radiologic study and treated by surgical removal or non-surgical methods including conservative treatment, enzymatic dissolution, and endoscopic removal. We have experienced a case of small intestinal obstruction due to a fragment of gastric bezoar of the patient without underlying etiologic cause. So we report the case with a brief review of literatures.

The purpose of this study was to analyze information about food and nutrition topics presented throughout the television broadcast media, thereby suggest the optimal communication method to give right information to the general public. To perform this study, total sixteen monitoring people were recruited and trained through monitoring practice before and during the study. Five domestic TV channels were selected to be monitored, for six months. For the best efficiency, all the monitoring people were divided into 8 teams based on the regional consideration. The statistical analysis of data was completed using SAS program. The main results of this study are as follows. First, the total reporting cases of information about foods and nutrition were 237 , among which about 30% was classified as appropriate and 70% as inappropriate based on the trained monitors' evaluation. Second, the analysis of contents about incorrect informations showed that the insufficient descriptions of terminology and contents were the highest. And insufficient scientific evidences, incorrect contents excessively entertainment-oriented, no provision of alternatives , improper selection of expert advisors were followed. These results suggest that systematical monitoring should be continued to reduce the frequency of incorrect communication thereby give the right information in food and nutrition area to the general public. And there should be a closely cooperated system to provide the professional information to broadcasting production team by establishing the strategic program. In order to do that, most importantly the advisory team should be organized to professionally connect mass media to corresponding specialists. In addition, more educational programs about food and nutrition should be developed to provide right information to the general public.

Purpose: This study aims to describe the characteristics of safety incidents and factors associated with injury for patients with Home Mechanical Ventilation (HMV) at the hospital. Methods: This is a retrospective study. Data were collected from the work log of respiratory home care nurses and the patients’ electronic medical records were investigated. In order to compare group differences, independent t-test and x 2 test were used. Associated factors with injury development were identified by generalized mixed modeling analysis controlling for age and gender. Results: A total of 304 patients on HMV were included in this study, among which 129 (42.4%) experienced 352 HMV-related incidents. Mean frequency of incidents for each patient was 5.11±3.98, ranged from 1 to 15 times.In 19.0% of the incidents, injury was developed. Types of incident and persons involved in the incidents were significantly associated with the patient's injury. In the case of the safety incidents, patient’s injury was significantly higher in accidents caused by respiratory circuit problems compared to those caused by problems with the ventilator operation by the medical staff (coefficient=1.25, p=.020). In addition, in the case of those involved in the safety incidents, patient’s injury was significantly higher in the accident caused by the patient family members or caregivers than that caused by the medical personnel (coefficient=1.25, p=.019). Conclusion In order to minimize injury caused by incidents in patients with HMV, hospitals need to provide systemic education to their medical staff and caregivers to enhance awareness of the importance of reporting and safety management.

BACKGROUND AND PURPOSE: Although the 15-item Geriatric Depression Scale (GDS15) is a widely used depression screening questionnaire, the implications of the GDS15 in patients with Alzheimer's disease (AD) are questionable. We designed this study to explore the GDS15 factor structure and the relationships between these factors and cognitive-behavioral aspects. METHODS: The GDS15, cognitive function tests, and the Korean-Neuropsychiatry Inventory were administered to 310 patients with probable AD, who were not medicated before visiting the hospital. Three factors were identified by principal components analysis. A bivariate correlation analysis was conducted to determine the relationships between factors and neurocognitive and behavior symptoms. RESULTS: Factor 2 was correlated with the Korean Boston Naming Test, calculating ability, the go-no-go test, the Controlled Oral Word Association Test (COWAT), the Color Word Stroop Test (CWST; words and color), aggression, depression, and apathy. Factor 3 was correlated with calculating ability, the Seoul Verbal Learning Test, immediate recall, copy, and delayed recall on the Rey-Osterieth Complex Figure Test, contrasting on the COWAT, and words and delusion on the CWST. We identified three factors and revealed that the GDS15 may be comprised of a heterogeneous scale. CONCLUSIONS: These results suggest that the GDS15 may be comprised of a heterogeneous scale and suggest multi-dimensional properties of the GDS15 in patients with AD.
