The melanotic neuroectodermal tumor of infancy(MNTl) is a rare, usually benign, pigmented lesion which most frequently involves the maxilla. Skull, brain, and mandible are other craniofacial sites; this anatomic region accounts for 87% of all cases. The vast majority of MNTl, nearly 95%, present in infants of both sexes within the first year of life. Most cases of MNTl follow a benign course, with a 15% propensity for local recurrence. MNTl is regarded as a primitive neuroectodermal tumor with polyphenotypic differentiation. We report a classical MNTl which occurred in left lower maxilla in 6-month old female infant. She developed an ill defined, firm swelling on the left alveolar ridge and gum during 3 weeks. Mass excision reveals ill defined, grayish-tan hard mass, measuring 2.0x1.6 cm. Microscopically, the tumor reveals irregular alveolar pattern of melanin-containing cuboidal cells and nests of small round cells. The immunohistochemical staining for melanoma-associated antigen, neuron-specific enolase and cytokeratin show positive reactions. Ultrastructural examination showed intracytoplasmic melanosome, tonofilament and desmosome.

PURPOSE: We applied lateral lithotomy position to the severe ureteral stricture cases supposed to fail with only retrograde approach. MATERIAL AND METHODS: From October 1997 to April 1999, 13 patients with severe ureteral stricture (lenghth>2cm or complete obstruction) supposed to fail with only retrograde approach and one patient with study. The causes of ureteral strictures were pelvic malignancy in 5, tuberculosis in 4, trauma in 2 and others in 2. The patient's ipsilateral shoulder was rotated and fixed like lateral position. And ipsilateral pelvis was elevated with sandbag or pad and rotated about 45 degrees, too. The retrograde approach was tried at first, if fail, antegrade approach was combined. RESULTS: We could insert ureteral stent via retrograde approach only in 3 patients and we needed aid of antegrade approach for passage through ureteral stricture in the other 11 patients (79%). Percutaneous antegrade approaches were combined in those 11 patients and we could pass the guide wire and indwell the stent in 10 of 11 patients (91%) using this position. CONCLUSIONS: The lateral lithotomy position was very helpful to the simultaneous retrograde and antegrade approach in severe fibrotic or malignant ureteral strictures.

OBJECTIVE: To investigate the patterns of the temperature effect on motor nerve conduction parameters according to various warming methods and to obtain the most valuable method of warming in clinical setting. METHOD: Twenty normal subjects were studied. After limb cooling in cold water, the cooled hands were warmed by hot pack, fan heater, and whirl pool. The median motor responses were recorded at abdnctor pollicis brevis after the stimulation at the wrist during warming at 1 min interval until the temperature increment reached plateau. We measured the temperature changes and conduction parameters were measured at each examination. RESULTS: The time constants for temperature increment and distal motor latency, duration, area of compound muscle action potentials showed shorter tendency by hot pack and whirl pool than by fan heater (p<0.05). For the measurement of distal motor latency, time constant of whirl pool (2.49 1.21 min) was shorter than that of fan heater (7.12 3.12 min) or hot pack (5.96 1.98 min) (p<0.05). CONCLUSION: These findings suggest that the use of whirl pool is the most effective method for warming of the cooled limb.

History taking, physical examination and x-ray study of both elbows were made on 55 senior high school, college and vocational baseball pitchers who visited the Department of Orthopedic Surgery of Hanyang University Hospital from March 1, 1980 to April 30, 1980. The results of this study were as follows: 1. Average age of 13 high school pitchers was 17.2 years, of 20 college pitchers was 20.1 years, and of 22 vocational pitchers was 23.4 years and average duration of pitching of high school pitchers was 3.8 years, college pitchers was 7.4 years, and vocational pitchers was 9.8 years. 2. Overhand type pitchers were 39(70.9%) and it was the most common pitching style. 3. 45(81.8%) complained elbow pain and the order of frequency was medial, lateral, and posterior. 4. 45(81.8%) showed hpertrophy of forearm and 38(69.1%) showed hypertrophy of arm. 5. Valgus deformity of the elbow joint was observed In 34(61.8%) and flexion contracture of the elbow joint was in 41 (74.5%). 6. Changes on x-ray were ossicle, traction spur, humeroulnar hypertrophy, narrowing of joint space, calciflcation of soft tissue and others. 7. Changes on x-ray were in proportion to duration of pitching and especially combined Iesions were observed more often ln overhand type pitchers.

PURPOSE: High interleukin-1 beta(IL-1beta) expression in the skin biopsy specimens of patients with Henoch-Schonlein Purpura(HSP) has been observed. We examined IL-1beta gene polymorphism in patients with HSP. The purpose of this study is to examine the relationship between IL-1beta gene polymorphism and renal involvement in HSP. METHODS: Patients from mideast Korea with HSP were studied. All patients had at least 6 months of follow up. Patients and ethnically matched controls were genotyped for IL-1beta gene polymorphism by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: Thirty-four patients(all younger than 15 years old) who had been diagnosed with HSP and 27 controls were examined. No allele or genotype differences between the HSP and control groups were observed. No significant association between the carriage of IL-1beta(-511) T allele and renal involvement(P=0.525, OR:1.417, CI:0.545-3.686) was found. CONCLUSION: In unselected patients with HSP, carriage of IL-1beta(-511) T allele does not appear to influence renal involvement.

OBJECTIVE: To assess the relationship between vaginal cytology and bone mineral density in postmenopausal women. METHODS: In 93 postmenopausal women, vaginal cytology smears were taken for maturation index, serum estradiol level and bone mineral density were also taken. the percentage of each cell type found By vaginal cytology was multiplied to its specific value:superficial cells, 1.0; intermediate cell, 0.6; parabasal cell, 0.2 and modified to maturation value. Bone mineral density was measured at lumbar spine using DEXA. RESULTS: The mean bone mineral density was 0.88+/-0.14g/cm2. Mean maturation value was 50.53+/-20.74 and it was related with age and bone mineral density. CONCLUSION: Maturation value of vaginal epithelial cell represents the influence of estrogen on bone mineral density.
