The present study was performed to evaluate clinical manifestations and histopatological findings of 95 patients with pityriasis roses who visited the Department of Dermatology in National Medical Center from October of 1979 to September of 1982. The results are as follows, 1. Clinical Manifestations: 1. The number of patients with pityriasis roses were 95, which occupied 0. 98/o of new out-patients in the department of dermatology in the same period. 2. In sex distribution, males were 36 and females were 59, with male to female ratio of I: l. 6. R. Age of onset varied from 13 months to 58 years with a mean of 26. 0 years and 68% of cases belonged to 15 years to 84 years. 4. Seasonal incidence was 32% in winter, 27% in summer, 22% in autumn and l9% in spring. 5. iMild prodromal symptoms developed in 8 cases(%) and itching was noted in 58 cases (61%), which was mild to moderate exeept for severe itching in 2 cases. 6. Herald patch was found in 42 cases (44%) and the predilection sites were the trunk and the thighs. 7. Daughter lesions could be classified into macular type 69 cases (73g), pa.pular type 22 cases (23%), pustular type 2 cases (2%), urticarial type 1 case (I,3 and purpuric type 1 case (1%) They appeared on the back (79%), the chest (74%), the abdomen(73%), the thighs (47%), the upper arms (40%), the lower legs (24%),the forearrns (22%), the neck (16%), the face (7 %), dorsa of the hands (4%) and dorsa of the feet(2%).

BACKGROUND: If the corrections of the cryptorchid testes are delayed, it may lead the patients to suffer loss of testes or fertility. So we purposed to analyze the present status of correction and the causes of delay and tried to emphasize the needs to educate and inform the ideal age for correction. METHODS: Total 363 cryptorchid patients who visited our hospital in 10 years from January 1987 to December 1996 were divided into 3 groups according to their ages at visit as under 2, 3 to 5 and over 6 years groups. We analyzed the operative findings of the 3 groups, compared the ratio of the over 6 group during the half ten years till 1991 to the same ratio after 1992 and also analyzed the causes of delay in 81 patients for whom the causes of delay could be identified in over 6 years group. RESULTS: The age distributions showed 88 patients(24.2%) of under 2 years group, 118 patients(32.5%) of 3 to 5 years group and 157 patients(43.3%) of over 6 years group. When we compare the former 5 years till 1991 to the latter 5 years after 1992, the number of the patients who underwent orchiopexy under the age of 2 were increased from 34 (19.1%) to 54(29.2%) and those over the age of 6 were decreased from 88(49.4%) to 69 (37.3%) but still in higher proportion. The intraoperative findings showed that the rate of atropic or smaller testes than normal size in over 6 years group(128 testes, 73.1%) were higher than those of under 2 years(10 testes, 9.8%) and 3 to 5 years group(28 testes, 20.2 %). The most common causes of delay in over 6 years group was recommendation by relatives or neighbors(36 patients, 48.1%) and the remainders were advices of doctors other than urologists(27 patients, 33.3%), poor economic status(8 patients, 9.9%) and unawareness of the anomaly(7 patients, 8.6%). CONCLUSIONS: To prevent the loss of testicular function or testis itself in patient with cryptorchidism, the early correction should be performed because the recommended age for the correction tends to be decreased. The public information for the recommended age should be provided and also educational programs for the primary physicians are supposed to be performed.

STUDY DESIGN: Changes of morphology and phenotype of cultured cells in media added lactate were observed. OBJECTIVES: To evaluate the effect of lactate on morphology and phenotype of cultured intervertebral disc cell. SUMMARY OF LITERATURE REVIEW: It was reported that lactate and pH were important factor in the degeneration of intervertebral disc. However the effect of lactate on morphology and phenotype of cultured intervertebral disc cell have not been studied. MATERIALS AND METHODS: Cells were dissociated enzymatically from rabbit nucleus pulposus. After attaining monolayer growth, the cells were incubated in media added 2mM or 5mM lactate. Total cell counts and morphological changes of the cells were periodically observed. Changes in cell phenotype were investigated by use of anti-collagen antibody stain. RESULTS: The cell groups added no lactate and 2mM lactate showed no difference in cell counts, morphology and phenotype. The cell group added 5mM lactate showed a reduction in final cell Counts and highel'ratio of fibroblastic cell in total population. Anti-collagen I Ab stained the Intra-and extra-cellular area of fibroblastic cells and intracellular area of chondrocytic cells. CONCLUSIONS: The current study suggests that high concentration of lactate inhibit intervertebral disc cell proliferation and accelerate morphological and phenotypical change to fibroblastic cell.

Cutis marmorata telangiectatica congenita(CMTC) is a rare congenital cutaneous vascular anomaly. The major skin findings are persistent, fixed cutis marmorata, telangiectasia, and phlebectasia. In approximately 50 % of patients, the disorder tends to be associated with various con-genital anomalies. We describe in this report a 4-month-old male infant with CMTC. The patient had red or violet marbled patches, telangiectases, and atrophy on the right arm present at birth. During the follow up period of 12 months, there was no change in the cutis marmorata pattern and telangiectases, whereas the atrophy has been less prominent than at the initial visit.

Agminated lentigines may be defind as a circumscribed grouping of small pigmented macules arranged in a small or large group, often in a segmental pattern, each macule consisting of a lentiginous epidermal proliferation of melanocytes. We report five cases of agminated lentigines in otherwise healthy persons. Histologic exarnination of the pigmented lesion revealed findings consistent with lentigo simplex.

MR images of seven patients with histologically documented synovial sarcoma were reviewed to find the suggestive or pathognomonic findings of the disease. MR appearance of the tumor was inhomogeneous, multiseptated mass with various degree of internal septation and infiltrative tumor margin. The signal intensity of the mass was slightly hyperintense relative to muscle on T1-weighted image and hyperintense relative to subcutaneous fatty tissue on T2-weighted image.

PURPOSE: In the diagnosis of pediatric urinary tract infection(UTI), the use of invasive methods, such as voiding cystourethrography(VCUG), is controversial. A retrospective study was carried out to evaluate the necessity for VCUG in assessing pediatric UTI. MATERIALS AND METHODS: Between April 2000 and March 2002, 70 children (60 boys, 10 girls) with symptomatic UTI were evaluated. All patients were evaluated with renal ultrasonography(RUS), 99mTc-DMSA renal scintigraphy(DMSA renal scan) and VCUG. The results of the VCUG were compared with RUS and similar comparisons made between the results of the VCUG and DMSA renal scans. Patients with both normal a RUS and DMSA renal scan were then evaluated for the frequency and grade of vesicoureteral reflux(VUR) on the VCUG. RESULTS: The mean age at the initial evaluation was 7.95 months, ranging from 1 to 52 months. RUS and DMSA scan abnormalities were found in 38(54.3%) and 26(37.1%) children, respectively. Of the 22 patients with VUR confirmed by VCUG, 11(50.0%) had an abnormal RUS, and 12 (54.5%) patients had abnormal DMSA renal scans. Of the 19 patients with both a normal RUS and DMSA scan, 4(21.2%, 6 kidney-ureter unit) were found to have VUR on VCUG. CONCLUSIONS: This study illustrated that a considerable number of patients may have significant VUR, despite normal renal ultrasonography and DMSA scans. Therefore, VCUG remains important in assessing pediatric UTI.

Bowens disease is an intraepithelial squamous cell carcinoma. It occur s anywhere on the surface of the body. Bowens disease involving the nail bed epithelium is very rate. Recently, some literatures showed that human papillomavirus is sssociated with squamous cell carcinoma of the finger by in situ hybridization or polymerase chain reaction. A 30-year-old housewife deve]oped longitudinal melanonychia with as imptomatic fissured nail plate on her right third finger. The hiat,ologic specimen showed diffuse anaplastic change confined to the nail bed epithelium. The subungual eyithelium was found to contain human papillomavirus DNA type 31/33/35 with the use of in situ hybridization.
