BACKGROUND: With rapid growth in the number of older Koreans and prevalence of dementia, exercise has been emphasized as first, second and third prevention of dementia. A few study, however, investigate effects of detraining and retraining in demented elders. Therefore, the purpose of this study was to investigate the effects of 24 week exercise followed by 12 week detraining and retraining on physical and cognitive function in demented seniors. METHODS: Thirty-five demented older adults were assigned into exercise and control group. Exercise group performed multi-component exercise, 2 times a week for 24 weeks. After 12 week detraining, subjects were retraining for 12 weeks. Subjects were tested four times on physiological variables, physical function and cognitive function. Ten subjects in exercise group and 6 subjects in control group were remained at final 48 week, and data from them were analyzed. RESULTS: There were no significant effects on physiological variable in both groups. However, 24 week exercise improved upper and lower body strength, flexibility, dynamic mobility and physical function. These effects, however, were significantly decreased in 12 week detraining period and increased again after 12 week retraining. There were significance group differences. Cognitive function was improved after 24 week exercise but decreased in detraining and retraining period and no significant difference between groups was shown. CONCLUSIONS: The present study suggests that positive effects after exercise tend to be reduced once one stops exercise, and be improved again after retraining. Therefore, strategies to encourage demented elders to exercise are needed.

OBJECTIVES: The sensitivity and accuracy of thermistor airflow signal has been debated. The purposes of this study were to compare apnea-hypopnea index(AHI) detected from a conventional thermistor signal and a nasal pressure transducer of airflow(NPT), to evaluate the value of NPT for the diagnosis of upper airway resistance syndrome (UARS), and to measure airway pressure fluctuations which produced respiratory arousals in UARS by naso-oro-esophageal manometer catheter. The subjects were 30 patients with obstructive sleep apnea syndrome [mild(540), 10), and 6 UARS patients. Airway resistance arousal in this study was defined as arousals which were not associated with apnea or hypopnea of thermistor signal, but showed significant decrease of nasal airflow pressure just before arousal and a prompt recovery of nasal airflow pressure after arousal, The airway pressure fluctuations were measured during 260 airway resistance arousals observed in 10 patients with OSAS, 2 with UARS. RESULTS: Mean AHIs of patients with OSAS were 33.4 by thermistor and 48.4 by NPT. The AHIs of mild, moderate and severe OSAS group were 10.2, 32.1, 65.4 respectively by thermistor and 23.1, 45.9, 76.4 by NPT. The mean AHI of patients with UARS was 3.2 by tehrmistor and 108 by NPT. The mean AHI of patients with nonspecific arousals was 2.7 by thermistor and 4.4 by NPT. The mean airway pressure changes during resiratory arousals of different groups were 8.7 cmH2O in mild OSAS, 11.4 cmH2O in moderate OSAS, 24.7 cmH2O in severs OSAS and 6.6 cmH2O in UARS. CONCLUSION: The nasal pressure transducer of airflow was more sensitive and accurate for assessing respiratory disturbances of patients with OSAS and was extremely helpful for the diagnosis of UARS without esophageal pressure monitoring. From the results, we would like to propose carefully the NPT diagnostic criteria for sleep disordered breathing as follows : NPT-AHI 5-15->UARS, 15-35->mild OSAS, 35-55->moderate OSAS and >55 ->severe OSAS.

The relative merits of cartilage scoring versus suturing in techniques for correcting the prominent ear remains a subject of debate among leading plastic surgeons. We compared a variety of echniques for correcting the prominent ear in 72 rabbit ears using scoring, horizontal mattress sutures, and combination scoring and suturing. The ears were splinted with a right-angle fold for 3 postoperative weeks, and the animals were sacrificed after 8 weeks. Suturing techniques in combination with scoring maintained an angulation significantly closer to the desired 90 degrees than cartilage scoring or cartilage suturing only(p<0.05). Histological analysis demonstrated a significant increase in cartilage hyperplasia by suturing alone, whereas the other techniques achieved only mild to moderate increases. We recommend cartilage scoring and suturing through skin incision on severe degrees of prominent ear, and cartilage needle scoring and buried suturing through slit incision on mile-to-moderate degrees of prominent ear.

A case of cutaneous cartilaginous tumor was diagnosed from solitary nadular skin lesion on a toe of 59-year old female. Lack of information about cartilage tumors in the dermatologic literature suggest that they rarely develop as supeficial lesions. General clinico-pathologic feature of the tumor is reviewed.

BACKGROUND: In recent years gonorrhea has been pandemic and remains one of the most common sexually transmitted diseases(STD) in the world, especially in developing countries. OBJECTIVE & METHOD: For the detection of a more effective therapeutic regimen and to assess the prevalence of penicillinase-producing Neisseria gonorrhoeae (PPNG), we have been studying patients who have visited the VD Clinic of Choong-ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. RESULTS: In 1995, 97 strains of N. gonorrhoeae were isolated, among which 41(42.3%) were PPNG. CONCLUSION: Since the prevalence of PPNG was reported as 21.9% in 1981, the rate fluctuated. However, in 1993, there was an increase up to 74.3%. Thereafter, the prevalence rate decreased to 64.3% in 1994 and 42.3% in 1995. These changes will therefore need continuous observation.

BACKGROUND: This study was performed to determine and compare the practice patterns of management of hypertension of the internists and family physicians in general hospitals and to compare them according to the JNC V guidelines. METHODS: Questionnaires were mailed to total 964 of internists and family physicians in general hospitals during May, 1996. 217 of them were returned with the response rate of 23.5%. Chi-square test and Fishers exact test were performed to examine the statistical difference between two groups. RESULTS: The mean age of the respondents was 39.1 and 77.9% of them were male. 65.4 % of hospitals for respondents were located in metropolitan cities. Concerning the number of measurements of blood pressure, 0.5% of the respondents measured just once before confirmation of the diagnosis. Items for physical examinations for initial evaluation were as follows; cardiac auscultation(94.0%), measurements of body weight and height(58.9%), abdominal examination(52.8%), auscultation for carotid bruit(41.7%), fundoscopic examination (25.6%). Regarding the laboratory tests, the frequency of evaluation of all item were higher than that of the physical examinations. For initial drug therapy, calcium channel blockers and ACE inhibitors were the most frequently chosen mediations. No difference was found between two specialties or tertiary and secondary hospitals in this trend. With educations for the life-style modification, 60-80% of the respondents educated the patients. No difference was found between two specialties except one item. CONCLUSIONS: As a whole the JNC V guidelines were not followed faithfully for the management of hypertension.

A case of pulsating exophthalmos is reported in a 50 years old Korean Woman. The complaints of this case were exophthalmos, chemosis on Rt. eye and intracranial bruit. The etiology of this case is considered due to toxemia of pregnancy and hypertension without trauma. A brief review of the literatures related with the etiology, symptom and therapy is made.
