The nevus of Ota is a benign dermal melanocytic lesion that most commonly occurs unilaterally in areas innervated by the first and second division of the trigeminal nerve. Acquired bilateral nevus of Ota-like macules(ABNOM) are located bilaterally on the forehead, temples, eyelids, cheeks, and/or nose. They usually occur in the fourth or fifth decade of life in women(rarely in men). In contrast to the nevus of Ota, ABNOM have not been observed in the mucous membranes of the oral cavity, nose, or eyes. Traditional treatments were palliative, risky electrocautery, or cryotherapy. These methods resulted in permanent pigmentary changes and/or scarring. Recently utilizing the principle of selective photothermolysis, the Q-switched Alexandrite laser has been reported to be successful in treating benign pigmentary lesions and tattoos. Our study evaluated the treatment of 127 patients with nevus of Ota and ABNOM with the Q-switched Alexandrite laser(755 nm, 100 nsec). Nevi were treated up to 7 times with 7-8 J/cm2 at a minimum of 6 weeks interval. Good therapeutic effects were gained (up to 50% improvement was seen in 89% of patients.) and our patients were very satisfied. No patients had permanent textural change or scarring. Treatment with on Alexandrite laser for nevus of Ota & ABNOM is considered to be a safe and effective method.

Small bowel capsule endoscopy (CE) was first introduced 15 years ago, and a large amount of literature has since been produced, focused on its indication, diagnostic yields, and safety. Guidelines that have made CE the primary diagnostic tool for small bowel disease have been created. Since its initial use in the small bowel, CE has been used for the esophagus, stomach, and colon. The primary indications for small bowel CE are obscure gastrointestinal bleeding, unexplained iron deficiency anemia, suspected Crohn's disease, small bowel tumors, nonsteroidal anti-inflammatory drug enteropathy, portal hypertensive enteropathy, celiac disease, etc. Colon CE provides an alternative to conventional colonoscopy, with possible use in colorectal cancer screening. Guidelines for optimal bowel preparation of CE have been suggested. The main challenges in CE are the development of new devices with the ability to provide therapy, air inflation for better visualization of the small bowel, biopsy sampling systems attached to the capsule, and the possibility of guiding and moving the capsule by an external motion controller. We review the current status and future directions of CE, and address all aspects of clinical practice, including the role of CE and long-term clinical outcomes.

BACKGROUND: Syncope is both one of the most common and one of the most challenging problems seen in medical practice. In spite of intensive medical evaluation, the cause of syncope remains unknown in a significant number of patients. In recent years, head-up tilt test has been of increasing interest as a diagnostic aids in patients with unexplained syncope. This study investigated the clinical utility of this technique in te evaluation of patients with vasovagal syncope. METHODS: Seven patients with unexplained syncope were evaluated with a 60 degree or 80 degree head-up tilt test with or without intravenous infusion of isoproterenol(1-4ug/min) in an attempt to provoke bradycardia, hypotension or both. There were 4 males and 3 females with a mean age of 35+/-8 years. RESULTS: 1) During head-up tilt test, vasovagal responses were provoked in 5 of 7 patients(71.4%) with syncope of unknown origin. During the test, there was no complication associated with the test. 2) During tilt-induced vasovagal reponse, mean systolic blood pressure decreased to 84+/-12mmHg from supine control of 125+/-21mmHg(p<0.01) and mean diastolic blood pressure decreased to 50+/-17mmHG from supine control of 76+/-14mmHg(p<0.01). 3) Five patients with positive results of the tests were followed up for 12months and they had a good outcome free of recurrence. CONCLUSION: Head-up tilt test appeared safely applicable test in patients with suspected vasovagal syncope and good prognosis was expected in the patients.

Chondroid syringoma is a rare primary skin tumor arising from eccrine sweat gland. In 1982, Nasse had found a primary skin tumor having similar morphology as in the mixed tumor of the salivary glands. In 1961, Hirsch and Helwig proposed more descriptive diagnostic term, "Choindroid syringma". The authors experienced two cases of chondroid syringma. The first case was a 47 year old male patient who had had a subcutaneous nodule in the right forehead for two months. It was a well circumscribed mass, that showed tan gray myxoid cut surface with firm consistency. Microscopically, it was a wel diagnosed as chondroid syringoma with tubular, branching lumina. The second case was a 51 year old female patient who had had a subcutaneous nodule in the left forehead for 3 months. It was well circumscribed, ad easily shelled out. It had a typical microscopic features of chondroid syringoma with small, tubular lumina.

Twenty nine cases of segmental tibial fracture were treated at Ewha Womans University Hopital, Department of Orthopedic Surgery, during the period from January, 1970 to December, 1984. The following results were obtained. 1. Most common fracture level was type I, high middle segment, occurred about 12 cases (41.4%). 2. In view of the higher incidence of open fracture (16 cases, 55.1%) and comminuted fracture (22 cases, 75.9%), fracture was caused by high velocity. 3. Various external and internal fixation methods were applied, but higher union rate was seen in the cases of Küntscher nailing and plating with bone graft. 4. Excluding the cases of type V, average union rate was 28.5 weeks and open fracture (ave. 29.6 weeks) required more longer union rate than closed fracture (ave. 26 weeks). 5. Higher rate of complication (21 cases, 72.4%) was noted than other types of tibial fracture. 6. Good result was obtained for treatment of 5 cases of delayed union or non-union by plating and bone graft than any other methods.
