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.

Direct intraarterial measurement of blood pressure is an important diagnostic procedure in critical patients and premature baby care. Direct measurement was more accepted and confident method in physician than the indirect methods. But the presence of a significant amplification of systolic pressure in peripheral artery may lead to important error. So we have investigated the degree of the systolic pressure amplification from the ascending aorta to the femoral artery in children. Pressure waves recorded in the ascending aorta, aortic arch, diaphragmatic level of the descending aorta, common iliac artery, and femoral artery in 37 patients with congenital heart disease, aged 9 months to 21 years old (mean 7.16 yrs old) during diagnostic cardiac catheterization. The results were as follows 1) Amplification of the systolic pressure increased progressively from the ascending aorta to the femoral artery (16.7%) 2) Diastolic pressure decreased progressively from the ascending aorta to the femoral artery (6.5%) 3) Mean pressure decreased progressively from the ascending aorta to the femoral artery (1.5%) 4) Pulse pressure increased progressively from the ascending aorta to the femoral artery (42.8%) 5) There was significant drop (7%) of the systolic pressure of the ascending aorta compared with that of left ventricle. The results showed that the peripheral amplifications were limited to the systolic and pulse pressure, but the diastolic and mean pressure in peripheral arteries were lower than that of central artery.

A various type of hairline and height of forehead is considered as a result of genetic effect. The conventional corrective surgical operation of low hairline in forehead has been too complicated and painful to apply, and also has many disadvantages such as scar, bleeding, risks of anesthesia. Recently four classes of devices are designed to remove hair with intense light beam : Nd-Yag lasers with carbon cream, the Ruby lasers, the Alexandrite lasers, and the polychromic broad band light source of flashlamp technology. The goal of these therapeutic modality is to destroy the melanin pigment selectively in hair follicle without injuring the skin for permanent epilation. We have been used long pulse infrared Alexandrite laser for treat low hair line in 27 patients from Dec. 1997 to Dec. 1998. We experienced 3 cases of temporary hyperpigmentation and 1 case of bulla, and the most of patients were satisfied in 89%. The average lengthening of forehead was 2.2cm (median line) and 2.3cm (paramedian line). We achieved successful result without permanent hyperpigmentation or scarring

Dyschromatosis universalis hereditaria was reported in 1933 by Ichikawa and Hiraga in Japan. This disease is characterized by small pigmented and depigmented mottled macules on the trunk and extremities. We report two cases of dyschromatosis universalis. Case one is a 47-year-old man presented with hypoand hyperpigmented spots on the trunk and extrexities. At about 30 years of age, he started to show pigmentary changes on the back, which became progressively spread to the other parts of the trunk and extremities. Case two is a 27-year-old man with numerous mottled hypo-and hyperpigmented spots on the trunk and extremities. He started to show pigmentary changes on the back about 12 years ago. This pigmentary changes also became progressively spread to the other part of the trunk and extrimities. There were no family history of similar disease. On physical exminations, both patients had hrown rice-grain sized pigmented and depigmented macules without scales and atropy on the trunk and extremites. Fontana-Masson stains revealed decreased and increased melar in granules in the basal cell layers in the hypopigrnented and hyperpigmented lesions respectively.
