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.

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.

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.

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.

55 consecutive anatrophic nephrolithotomies on 53 patients performed between July, 1983 and June, 1990 were reviewed. The patients (36 male and 19 female) ranged in age from 3 to 72 years. The operation time averaged 219.8 minutes with a range of 120-330 minutes, and the ischemic time ranged between 20 and 90 minutes, with a mean of 43.5 minutes. Postoperative complications developed in 18 patients, which were such as persistent urinary tract infection in 5cases (9.4%), atelectasis in 4 (7.5%), transient urine leak in 2 (3.8%), delayed bleeding in 2 (3.8%) and urinary retention in 2 (3.8%). Postoperative residual stones were identified in 15 (27.3%), but in 8 of these 15patients stones were delivered spontaneously and thus 48 of 55 cases (87.3%) became stone free. The recurrence of stone was noted in 2 out of 48 patients during the short follow up period. Anatrophic nephrolithotomy seems to be an effective method compared to other procedure because of decreasing recurrence of stone by complete stone removal and reconstruction of abnormal collecting system.

Epidermoid Cyst is a very rare benign neoplasm of the testis which represents about 1% of all testicular tumors. Ultrasonography findings of epidermoid cyst are so variable in reported cases that it is not eas y to diagnose preoperatively. The echogenecity of mixed echoic. it may show hyperechoic rim, and rarely shows target apperance. Target appearance may be a specific finding of epidermoid cyst, and it may be helpful to diagnose preoperatively. we describe a case of epidermoid cyst of the testis demonstrating double target sign on ultrasonography.
