Pyelocaliceal diverticulum is a well recognized uncommon entity, usually noted incidentally on excretory urography by lack of clinical symptoms, About 500 cases had been reported with similar entity till 1975. We report 6 cases of stone-containing pyelocaliceal diverticula and additional one case and the literature has been reviewed briefly.

Infectious disease consultation contributes to optimal antibiotic use as well as improved treatment outcomes in many infectious diseases, especially severe infections like bacteremia. However, communication and language matter in consultations between clinicians. Communication barriers are even more complex among professionals who speak Korean, since there are significant challenges for practicing medicine while relying on language translations. This review aims to address some of the components that should be included in infectious diseases consultations for Korean-speaking specialists.

Growth stimulatory/inhibitory factors and their receptors are the important mediators of control of epithelial cell proliferation and differentiation. The aim of this study was to observe the distribution of epidermal growth factor receptor (EGFR) and transforming growth factor-beta1 type II receptor (TbetaRII) during carcinogenesis of oral squamous cell carcinoma (OSCC). Formalin fixed, paraffin embedded tissue from 25 oral leukoplakias (OL) and 15 OSCC was immunostained by avidin-biotin complex method. In OSCC, the carcinomatous area and the adjacent dysplastic/ hyperplastic area were examined. In OL, the hyperplasia and the epithelial dysplasia were examined. Monoclonal anti-EGFR Ab and polyclonal anti-TbetaRII Ab were applied. EGFR was mainly expressed in the basal layer and was increased with epithelial dysplasia in OL. TbetaRII was not detected in the basal cell layer and dysplastic area in OL. In contrast, the dysplastic area adjacent to OSCC showed positivity in the entire layer including the dysplastic area. In all cases of OSCC, both EGFR and TbetaRII showed positive reactions. EGFR was increased with the progression to the malignancy, and the expression pattern of TbetaR II was altered to be positive in the basal cell layer with progression to malignancy. These results suggest that the expression of EGFR appeared to be an early event and TbetaR II may be related to malignant transformation during oral carcinogenesis. The expression pattern of EGFR and TbetaR II may contribute to predict the risk of the development of carcinoma in oral premalignant lesions.

Partial Unilateral Lentiginosis (PUL) is a rare pigmentary disorder characterized by the numerous lentigines confined to a body segment, with a sharp demarcation at the midline. We report two cases of PUL. A 38-year-old woman had asymptomatic discrete small hyperpigmented macules that were scattered on the T7~L1 dermatomes on the left side of her trunk and were clearly demarcated in the midline on both anterior and posterior sides. In the other case, an 18- year-old woman had hyperpigmented macules that were scattered on the left neck, shoulder, and anterior chest. Other anomalies including neurofibromatosis, neurologic anomalies, and multiple lentiginous syndrome were not related in both cases. We report two cases of PUL having no other anomalies.

Herpes simplex virus infections, with their increasing tendenes are one of the most common infectious diseases. But there have been no systematic investigations on the prevalence of HSV antibodies according to ages in Korea. We therefore decided to investigate this prevalence using micro-neutralization tests. Blood samples were collected from 502 randomly selected men and women, 5 months to 77 years of age who were outpatients or hospitalized patients at the Hanyang University Hospital between 1990-1991. Students at the Hanyang university college of medicine, and other volunteers were also tested. All of the serum samples were assayed for antibodies to HSV useing the microneutralization test. The Cos strain of HSV 1 and the YHS 2-1 strain of HSV 2 were use3 in our study. The antibody titers were expressed as the highest serum dilution causing 80% plaque reduction. The individuals with a neutralizing antibody titer of 1: 2 or higher to HSV 1 were regardel as having the antibody to HSV l. To determine HSV 2 antibody activity, the II/I index was used (II/I mdex : log HSV1 antibody titer/log, HSV 2 antibody titer, lI/I index >0.85) The results obtained were the followings : 1. HSV 1 antibodies were found at a relatively high rate in young a es and its prevalence gradually increased with age. 2. HSV 1 antibody titers iricreased with age. 3. HSV 2 antibodies were not found in children under 11 years of ae but were found in teenagers at a relatively low rate. The prevalence tended to increas with age. 4. HSV 2 antibody titers showed a higher value in those over 31 years of age.

We report a case of a photosensitivity reaction in a 76-year-old inale induced by chlorpropamide ingestion. The patient had erythematous scaly patches on the sur. -exposed areas, A phototest revealed the decreased minimal erythemal dose(MED) to UVA(5J/cm). A photopatch test and photo-scartch test with 1% chlorpropamide ointment and 0.1% chlorpropamic!e .olution were all negative. An oral provocation test was performed, which showed a positive result with marked decrease of MED to UVA (5J/cm). After the cessation of chlorpropamide, his skin lesions were improved markedly with complete loss of photosensitivity. Macular hypopigmentations (leukcme.anoderma) appeared on the previous erythematous patchy ereas, but disappeared during the follow-up period.
