OBJECTIVES: Physical exercise has become popular in recent years. It has been known that exercise is related to the development of heartburn, belching, regurgitation and chest pain. However there are few data concerning the effect of exercise on esophageal motor function and gastroesophageal reflux. We evaluated the effect of exercise intensity on esophageal motor activity and gastroesophageal reflux. METHODS: We studied healthy volunteers (15 males, age: 28+/-5 years, BW: 68+/-10kg) using a 24 hours ambulatory esophageal pressure, pH catheter and portable digital data recorder (Microdigitrapper 4Mb, Synetics Medical, Sweden). Subjects exercised on a treadmill (Marquette Case 15 Electronic INC) at 50% and 70% maximal heart rate for 30 min. Subjects rested 2 hours before exercise (base line) and for 30 min between exercise sessions. RESULTS: 1) Exercise of 50% maximal heart rate reduced total contraction, contraction duration, percentage of simultaneous contraction and repetitive contraction, (P<0.05) but increased percentage of contractions above 20mmHg amplitude (P<0.05). 2) Exercise of 70% maximal heart rate decreased total contraction, esophageal amplitude, contraction duration and percentage of peristaltic contraction, (P<0.05) but increased percentage of simultaneous contraction (P<0.05). 3) Gastroesophageal reflux was not change on both 50% maximal heart rate and 70% maximal heart rate exercise. CONCLUSION: More propulsive esophageal motility are induced following exercise of 50% maximal heart rate, but not 70% maximal heart rate.

The antiarrhythmic effect of oral amiodarone was evaluated by 24-hr Holter monitoring in 12 patients with frequent and/or complex ventricular ectopy. Amiodarone was administered as following schedule; 600mg a day for the 1st week, 400mg a day for the 2nd week and 200mg a day, 5 days a week from the 3rd week. In 9 patients, the frequency of VPC decreased significantly or the grade of VPC changed to the more benign grade, so we considered them as "Effective Group" (75%). In 7 patients, both the frequency and the grade of VPC improved, so we considered them as "Excellent Group" (58%). No significant side effect was observed during investigation. We concluded that amiodarone is very effective antiarrhythmic drug and has no serious side effect during a short-term observation.

Atrophie blanche is a rare vasculitis reported by Milian in 1929, that is characterizel by small erythematous, telangiectatic purpura which developes central hemorragic curst or painful ulceration and heals with atrophic white scar several months later. It is seen more commonly in middle-aged women and become worse in summer. It manifests primarly on the lower legs, ankles and dorsa of the feet, rarely on the elbows and dorse of the hands, where are the areas of the poor blood circulation. This case was 45 year-old woman who had suffered from periodic painful ulceration on the legs, ankles, dorsa of feet k hands and. elbows for about 18 years. Histopathologic findings showed fibrinoid degeneration R partial occlusion in the capillaries and mild perivascular chronic inflammatory cells infiltration in the upper corium. The lesion was not so improved by systemic k local corticosteroid therapy for about 3 months,

A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.
