Penile melanosis is a new disease entity which is benign and different from pigmented nevus and acral lentiginous melanoma in situ. A 20-year-old man had hyperpigmented macules on the glans penis and penile shaft for 5 years. Clinical and histologic findings were consistent with penile melanosis and giant melanosome complexes were observed ultrastructurally.

Discoid meniscus has been defined as a morphological anomaly, and several clinical classification has been proposed. Commonly used classification is Watanabes classification; complete, incomplete and Wrisberg ligament type discoid meniscus. It is a relatively more common disease of the knee in Korea and Japan than western countries. Eighty-one discoid meniscal tears which were operated arthroscopically between the period of June, 1991 and August, 1996 were reviewed retrospectively. The purpose of this study is to analyze the pattern of the tear and the extent of arthroscopic resection according to the arthroscopic classification of the discoid meniscus. Thirty-three cases were classified as complete and forty-five cases as incomplete and three cases were Wrisberg ligament type. The major pattern of the tear in the complete type lesions was horizon- tal(in twenty-three) and complex(in seven) tear. Of the knees that had an incomplete type lesion, longitudinal(in ten including six bucket-handle tear) and degenerative tear(in eight) were observed more frequently, and horizontal tear(in ten) less frequently than that of the complete type. The extent of arthroscopic resection of the discoid meniscus was related to the pattern of tear and type of the discoid meniscus. For the majority of the horizontal tear, arthroscopic partial meniscectomy (twentyeight of thirty-four) was performed, but arthroscopic subtotal and total meniscectomy was performed more frequently for longitudinal tear, complex tear, and Wrisberg ligament type.

From March 1992 to June 1994, we experienced five failed cases of anterior cruciate ligament reconstruction. Four out of five cases had reconstruction in other hospitals. Two of them had anterior cruciate ligament reconstruction using artificial ligament, one using bone-patellar tendon-bone auto- graft, and one using bone-patellar tendon-bone autograft augmented by artificial ligament. The remaining one case had arthroscopic anterior cruciate ligment reconstruction using bone-patellar ten- don-bone autograft in Asan Medical Center. We performed arthroscopic revision anterior cruciate ligament reconstruction using allograft in four cases and bone-patellar tendon-bone autograft in one case. All cases were treated with vigorous postoperative rehabilitation program including postoperative immediate range of motion(ROM) exercise and muscle strengthening exercise. Postoperative results were evaluated by Lysholm knee score in average 17.2 months(range from 12 months to 25 months). The average Lysholm score improved from 49.8 to 81.4. At follow-up study, anterior drawer test with Telos device revealed 2mm of average side to difference.

Melanosomes were isolated from the human hair by graded centrifugation and identified by transmission and scanning electron microscopic examination. Melanosomes were separated from the keratinous structures by treating with strong NaOH solution for 15 hours. The keratinous structures were removed by centrifugation ai 2,500xg and 3,500xg for 10 minutes respectively at 0 ℃. The isolated melanosomes were collected by centrifugation at 7,800xg at 0 ℃. Scanning electron microscopic examination made it possible to evaluate the global structure of purified melanosomes.

Distal renal tubular acidosis (RTA) is a biochemical syndrome as a deficiency of hydrogen in secretion by the distal tubule and collecting duct. Owing to the nature of the defect, hyperchloremic non-anion gap metabolic acidosis and high urine pH despite severe systemic acidosis is characterized. Typical manifestations of distal RTA are growth retardation, rickets, polyuria and nephrocalcinosis. We experienced a case of distal renal tubular acidosis in a 4 years old female child who complained of growth retardation and gait disturbance. She showed typical hyperchloremic non-anion gap metabolic acidosis and persistent high urine pH. In radiographic examination. we found delayed bone age and severe rachitic changes of wrist, elbow, and knee as well as nephrocalcinosis. In ammonium chloride loading test, high urine pH persisted despite the lowering blood HCO3- concentration. After alkali therapy, she is in well condition with excellent growth velocity and absence of rachitic changes.
