PURPOSE: The purpose of this study was to identify associated factors of chewing discomfort among community-dwelling elderly. METHODS: The study was cross-sectional design and secondary data analysis using the 6th Korea National Health and Nutrition Examination Survey. Among the total of 7,550 participants, data was analyzed with 1,126 adults aged 65 years and over. Chewing discomfort was assessed by the perceived chewing discomfort. Multivariate logistic regression analysis was used to find the associated factors of chewing discomfort. RESULTS: Along with 61.7% of the participants reported having chewing discomfort, 85.2% reported to perceive poor oral health and 35.0% had oral pain. In multivariate logistic regression, perceived oral health (OR 3.22, 95% CI 2.24~4.63), oral pain (OR 2.46, 95% CI 1.76~3.43), activity limitation (OR 1.71, 95% CI 1.05~2.80), teeth requiring treatment (OR 1.61, 95% CI 1.14~2.26), number of remaining teeth (OR 1.60, 95% CI 1.22~2.10) and educational level (OR 1.56, 95% CI 1.15~2.12) were the significant predictors of chewing discomfort. CONCLUSION: The prevalence in chewing discomfort was high in elderly Koreans and various factors were associated with chewing discomfort. To improve chewing ability, it is suggested that the national level of policies offer strategical oral health programs in this population.

A 49-year-old woman with anemia who developed headache and seizure after blood transfusion was diagnosed with posterior reversible encephalopathy syndrome (PRES). Magnetic resonance imaging showed typical PRES findings including lesions in bilateral parieto-occipital subcortical white matter and overlying cortex. Only a few cases of PRES after transfusion have been reported and this case is unique in that there was a latent period between infusion and development of PRES. We postulate that rapid change of hemoglobin level may disrupt cerebral autoregulation and result in delayed PRES. We suggest that neurological symptoms after blood transfusion should be appropriately investigated.

Native valve endocarditis (NVE) without preexisting structural valve or congenital cardiac malformation especially in pediatric group is rare. A case of isolated tricuspid valve endocarditis in a 7-year-old child without any cardiac malformation is described. This child had suffered from fever and productive cough for 3 weeks. Blood culture grew Staphylococcus aureus. Fever was not controlled even with proper antibiotic treatment. Transthoracic echocardiogram and lung perfusion scan revealed a large vegetation on the tricuspid valve with multiple embolism Surgical procedures included vegetectomy partial cusps resection and pericardial patch valvuloplasty. Th patient was in NYHA class I during follow up.

OBJECTIVES: The aims of this study were to find and compare the effect of directional (DIR) processing of two different hearing aids via both subjective and objective methods, to determine the association between the results of the subjective and objective evaluations, and to find out individual predictive factors influencing the DIR benefit. METHODS: Twenty-six hearing aid users fitted unilaterally with each two different experimental hearing aid performed modified Korean Hearing in Noise Test (K-HINT) in three DIR conditions; omnidirectional (OMNI) mode, OMNI plus noise reduction feature, fixed DIR mode. In order to determine benefits from DIR benefit within a hearing aid and compare performance of the DIR processing between hearing aids, a subjective questionnaire was administrated on speech quality (SQ) and discomfort in noise (DN) domain. Correlation analysis of factors influencing DIR benefit was accomplished. RESULTS: Benefits from switching OMNI mode to DIR mode within both hearing aids in K-HINT were about 2.8 (standard deviation, 3.5) and 2.1 dB SNR (signal to ratio; SD, 2.5), but significant difference in K-HINT results between OMNI and OMNI plus noise reduction algorithm was not shown. The subjective evaluation resulted in the better SQ and DN scores in DIR mode than those in OMNI mode. However, the difference of scores on both SQ and DN between the two hearing aids with DIR mode was not statistically significant. Any individual factors did not significantly affect subjective and objective DIR benefits. CONCLUSION: DIR benefit was found not only in the objective measurement performed in the laboratory but also in the subjective questionnaires, but the subjective results was failed to have significant correlation with the DIR benefit obtained in the K-HINT. Factors influencing individual variation in perceptual DIR benefit were still hard to explain.

Mitochondrial myopathy is characterized by variable clinical manifestations from mild limb weakness to fatal respiratory failure and central nervous system sequela. But it is a rare event that sleep disordered breathing become a clue of diagnosis for mitochondrial myopathy. We report a case of a 21 year-old man who was diagnosed as mitochondrial myopathy during the investigation for the possible cause of chronic hypoventilation syndrome. Before being admitted to our hospital, he was suspected as having sleep apnea syndrome in another hospital. We re-evaluated the history, physical examination, laboratoy findings and polysomnography in detail. Severe hypoxemia was noted during REM sleep on nocturnal polysomnography and the diagnosis of mitochondrial myopathy was made by muscle biopsy in rectus abdominis muscle. We treated him with bilevel positive airway pressure therapy during sleep and it could reverse the hypoxemia during REM sleep. He could be discharged with improved condition and is being well with the use of this ventilatory assistance.

Intramural esophageal dissection is a rare disorder that's characterized by a lengthy laceration between the mucosal and submucosal layers of the esophageal wall, and the esophageal wall is without perforation. The three different types of acute esophageal injury are a mucosal tear (Mallory-Weiss syndrome), full-thickness rupture (Boerhaave's syndrome) and intramural esophageal dissection. Most intramural esophageal dissections respond to conservative management with a very good prognosis. This rare condition should be considered in patients who present with acute chest pain, dysphagia or odynophagia, and particularly in the presence of a bleeding disorder or where there has been recent administration of antiplatelet medication, anticoagulants or thrombolytics to avoid inappropriate treatment with surgery. We present here a rare case of intramural dissection of the esophagus that occurred when the patient was taking antiplatelet medication.

Ectopic pregnancy is a common medical problem that is difficult to diagnose and potentially may lead to significant mortality or morbidity. The incidence of ectopic pregnancy is definitely increasing due to the rise in pelvic inflammatory disease (PID), pelvic surgery, intrauterine device (IUD), and assisted reproductive technologies, such as in vitro fertilization and embryo transfer (IVF-ET). Combined ectopic gestations are much rare and their true incidence is unknown. Multiple ectopic gestations may occur in a variety of locations. The majority involve one or both fallopian tubes. We report a case of combined tubal and cervical pregnancies, and discuss their management.

The purpose of this study was to identify important items from the medical records to be used in the standardized discharge abstract. Common items were identified by analyzing medical records from the 11 largest hospitals in Seoul. Non-common items were identified by a questionnaire survey from the directors of medical record departments of 152 teaching hospitals. The results of research was follows; 1. Thirty eight common items were included in the analyzed sheet of 11 hospitals. 2. Eighty two non-common items were identified from the analyzed. Of these,10 items were found to be important items for the discharge abstract. 3. Another 26(half) or 18(first quarter) important non-common items were identified from the survey. 4. It was notified in the non-common standardized items group that the importance of some items like the patient's occupation, underlying cause of death, nosocomial infection, complications, house staff code in charge of completing records, and items concerning quality improvement showed difference by the number of beds. The importance of house staff code who is responsible for completion of the record also showed statistically significant difference by the number of beds per medical record professional and by regions. The item of the types of nosocomial infection also showed statistically significant difference between the regions. Most hospitals obtain a lot of medical information from the computerized discharge abstract. One of the results of the study showed that the concerned sheet can housed as both the data for the medical insurance claims and the basic data for medical quality improvement. Therefore, the discharge abstract should be regarded as the most necessary sheet to be standardized. It was found that 92.8% of the directors of medical record departments of nationwide teaching hospitals acknowledged the necessity of standardization of medical record data set.
