The multifactorial etiology of BCC(basal cell carcinoma) are incompletely understood, including factors leading to multiple lesions in some patients. Cases of multiple BCCs reported in the literature have been associated with UV irradiation, inorganic arsenic poisoning, X-ray therapy, hematologic malignancy and several genodermatoses such as nevoid BCC syndrome, albinism, xeroderma pigmentosum. Multiple BCCs presented on the sun-protected areas, lacking predisposing risk factors which have been known, is rare skin condition. However, it suggests that there may be an unknown genetic susceptibility to the development of multiple BCCs. We report a rare case of multiple BCCs, which had developed only on the sun-protected areas in 64-year-old man, without any known predisposing causes.

To determine the concentration and the physiologic role of metal components in blood plasma and seminal plasma in relation to male infertility, the concentrations of twelve metal components in blood plasma and seminal plasma including Na, Mg, K, Ca, Cr, Mn, Fe, Cu, Zn, Se, Cd and Pb were measured by atomic absorbance spectrophotometery or ion selective electrode analysis. Semen and blood samples were obtained from a total of 110 men including 70 male infertility patients, 20 vasectomized persons and 20 fertility proven volunteers visited to the Male Infertility Clinic of Pusan National University Hospital. The concentrations of Ca, Zn, Mg, Cr and Cd in control group were higher in seminal plasma than in blood plasma, and additionally Pb were higher in infertility group. The concentrations of all metal components revealed no significant difference according to patients' age, resident, occupation, sperm density, motility and hormone level in blood plasma, but some metal components including Ca, Mg, Cu, Mn, Cd and Pb revealed a significant difference according to each these parameters except patient's age in seminal plasma. The concentrations of Mn, Cd and Pb in the vasectomy persons were higher than in the infertility group III including testicular and epididymal factors, but not in blood plasma. We conclude that the quantitative changes of metal components in the seminal plasma may have effects on not only spermatogenesis and sperm function, but also contribute to diagnostic parameter according to organ specificity of the metal in the male reproduction.

There is debatable opinions as to the nature and clinical significance of the changes that may occur in the spine after posterior spine fusion performed in growing children. Clinical survey is known to be difficult because X-ray films in children are not easy to interpret and measure in the presence of disease and accuracy is uncertain due to magnification on X-ray films. Authors selected 8 cases of tuberculous spondylitis which were managed with posterior spine fusion under the criterias that cases had surgery under 10 years old, no evidence of pseudoarthrosis clinically and roentgenologically on serial examinations at least once 1 year, follow-up more than 2 years since 3 months after surgery, enough spines are included on lateral X-ray films, and accurate measurement and correction of magnification are possible. The cases were surveyed for changes occured in fused spines after posterior spine fusion and the results were as follows: 1. There was actual lengthening of grafted bone mass after solid fusion in all cases although the amounts were minimal. 2. The fused spines grew 46% on an average less than adjacent normal unfused spines. 3. The vertebral bodies of fused spines grew nearly same as the adjacent normal vertebral bodies. 4, The intervertebral disc spaces of the fused spines were narrowed in all cases. 5. The intervertebral angles had tendency to increase and kyphosis angles to decrease.

The adult long bone is known to be very rarely infected by the hematogenous route because of the different vascular pattern from the children and the clinical pattern of the primary hematogenous pyogenic osteomyelitis occurred in adult long bones is very different from the well known acute osteomyelitis of the children. The authors studied 16 cases of the hematogenous pyogenic osteomyelitis occurred in the adult long bones without previous history of the bone infection and the diagnosis was confirmed by histological and/or bacteriological examinations. The cases were 8 males and 8 females having ages between 19 years to 50 years old. The involved bones were 6 femurs, 5 tibias, 2 humeri and fibulas and a ulna and the involved sites were 10 in shafts and 6 in ends of long hones. All the cases had insidious onset without acute symptoms and the course was rather subacute form. There were three different types based on x-ray findings and operative findings. 5 cases were cortical type having localized cortical thickening in the shaft around one or several small intracortical ahscesses, 7 cases were medullary localized type having well circumscribed bone abscess and 4 cases were medullary diffuse type having extensive irregular destruction with occasional small sequestrum. The problems of these cases were differential diagnosis because there were no typical symptoms or signs of the infection and the x-ray findings were very confusing, but most of the cases healed well hy simple surgery and antibiotics.

We analyzed the MR findings of spinal epidural mass in 23 patients retrospectively. MR images were performed at 1.5T unit. The lesions were confirmed as metastasis(12 cases), lymphoma (2 cases), leukemia(1 cases), multiple myeloma(2 cases), meningioma(3 cases), neurofibroma(1 case), dysraphism with lipoma(1 case) and lipomatosis(4 cases), Most MRI examinations consisted of T1, proton density and T2 weighted sagittal imaging of the spine, with additional pulse sequences or image planes as needed for clarification. The level of the spinal epidural mass was cervical spine level in 2 cases, thoracic in 15 cases, lumbar in 7 cases, and sacral in 2 cases. The location of epidural mass within the spinal canal was eccentric in 20 cases, multiple in 2 cases, and encircled in 4 cases. Paraspinal mass was seen in 11 cases. Signal intensity of epidural mass was variable. The marrow of spine revealed low signal intensity(SI) on TIWI and high SI on T2WI in 14 cases. In conclusion, MRI is a useful diagnostic tool for the evaluation of spinal epidural mass.

BACKGROUND: Recently, it has been suggested that autoantibodis face of melanocytes are prevent in the sera of vitiligo patients. However, these autoantibodies exist, whether they are specific for vitiligo a vitiligo patients possess them. In addition, the specificity of the iti lecular weight of the antigen are all unsolved areas demanding further. OBJECTIVE: To investigate the possible role of autoimmune microvitiligo, this study was designed to verify the presence of auto and vitiligo antigen from the surface of melanocytes, the specificity of gene specific antigens on the sunever, it is not known whether ents, and what percentage of goantigen and the exact moier research. anisms in the development of bodies in vitiligo patients, the utoantibodies and vitiligo anti. METHODS: Indirect immuvofluorescent microscopy, flow cytoriiety, and ELISA was done to compare the reactions between melanocytes and sera. SDS-PAC island immunoblotting were used for the identification of vitiligo antigen. RESULTS: Vitiligo sera showed more prominent fluorescence and higher optical density on the surface of melanocytes than normal sera. Forty-four percent of vitiligo sera was directed to melanocytic surface antigen with a molecular weight of 65kDa. The sition assay using rabbit antimelanocytic antibody showed an inhibition of the reaction betw er vitiligo sera and melanocytes in ELISA and immunoblotting. CONCLUSION: A surface antigen of 65kd was identified from melanocytes and 44.4% of the vitiligo sera showed positive reactions to this antigen.

Retinal arteriovenous crossing sites are important because they are generally the points at which. in branch retinal obstruction, a blockage of venous blood flow occurs. We evaluated retrospectively the cases of 54 patiens wIth a recent temporal branch retinal vein occlusion to determine the relative anatomic position of the obstructed vein in relation to its crossing artery. In 54 (100%) of 54 eyes, the artery lay antenor to the vein, toward the vitreous cavity. In the control corssing site, the artery lay anterior to the vein 41.3% (J9/46) of the time (p<0.01) The second control group, which was obtained by examining all of the first-and second-order, without BRVO, consisted of 103 crossing sites. In this second control group's artenovenous crossmgs, the arteries were situated anteriorly in 83 (80.6%) of 103 crossing sites (p<0.005). Our observation that the artery lies anterior to the vein at the all of BRVO crossing sites contributes further evidence that mechanical factors play a prominent role in the causing BRVO.
