PURPOSE: The purpose of this study was to evaluate the accuracy of Tc-99m DTPA diuretic renal scans in children upper urinary tract. MATERIALS AND METHODS: We reviewed diuretic renal scans of 14 pediatric patients (age range: 3 days to 4 years) with unilateral hydronephrosis diagnosed by ultrasonography. Diuretic renal scan was done using Tc-99m DTPA and standardized protocol. In 3 neonates, diuretic renal scans were performed within 1 week and 3-7 months after birth. RESULTS: Six patients required pyeloplasty and eight were managed conservatively. All 6 patients requiring pyeloplasty were diagnosed as having ureteropelvic junction obstruction in the diuretic renal scan. In these 6 patients, post-operative renal scans at 3-12 months after surgery were converted to nonobstructive pattern in 5 and a nonobstructive patterns in 1. In 3 patients who underwent diuretic renal scan within 1 week after birth., nonobstructive patterns of initial scan were coverted to obstructive patterns in the follow-up scan. However, all patients with nonobstructive diuretic renal scans performed after the neonatal period did well on serial ultrasonography and showed favorable clinical outcome without progression to obstruction. CONCLUSION: Tc-99m DTPA diuretic renal scan with standarized protocol is useful in assessing suspected ureteropelvic junction obstruction in children as an initial diagnostic or post-operative follow-up modality. Nonobstructive or indeterminate scan RESULTS in the neonatal period requires follow-up scan to monitor development of the obstructive pattern.

Meningiomas are usually thought of as firm solid tumors and most standard references make no mention of cystic meningiomas. Although several cases of cystic meningioma have been reported in the literature and their neuroradiological features discussed, the rarity of this entity makes its preoperative diagnosis difficult. Recently, the authors encountered a case of cystic meningioma, which was thought as ependymal cyst or infarction, preoperatively. In this report the authors discussed its clinical, neuroradiological and pathological characteristics with brief reviews of the literature.

Tailgut cysts in retrorectal or presacral space are rare and the derivatives of the embryonic post-anal gut. It is thought to arise from vestiges of embryonic hindgut. The lesions were usually multicystic and lined by a variety of epithelial types, including ciliated columnar, mucin-secreting columnar, transitional, and squamous epithelium. Tailgut cyst has been found in men and women of various ages but is more common in women and is usually associated with middle age. They may be the source of the chronic perirectal symptoms and rarely undergo malignant change, so early diagnosis and accurate evaluation is important. Complete surgical resection should be considered because of a long term risk of malignant change. We report two cases of tailgut cyst.

PURPOSE: Leptin has been considered a link between metabolic state and reproductive activity. Defective reproductive function can occur in leptin-deficient and leptin-excessive conditions. The aim of this study was to examine the effects of centrally injected leptin on the hypothalamic KiSS-1 system in relation to gonadotropin-releasing hormone (GnRH) action in the initial stage of puberty. METHODS: Leptin (1 microg) was injected directly into the ventricle of pubertal female mice. The resultant gene expressions of hypothalamic GnRH and KiSS-1 and pituitary LH, 2 and 4 hours after injection, were compared with those of saline-injected control mice. The changes in the gene expressions after blocking the GnRH action were also analyzed. RESULTS: The basal expression levels of KiSS-1, GnRH, and LH were significantly higher in the pubertal mice than in the prepubertal mice. The 1-microg leptin dose significantly decreased the mRNA expression levels of KiSS-1, GnRH, and LH in the pubertal mice. A GnRH antagonist significantly increased the KiSS-1 and GnRH mRNA expression levels, and the additional leptin injection decreased the gene expression levels compared with those in the control group. CONCLUSION: The excess leptin might have suppressed the central reproductive axis in the pubertal mice by inhibiting the KiSS-1 expression, and this mechanism is independent of the GnRH-LH-estradiol feedback loop.

Leiomyosarcoma of the penis is an extremely rare disease. We have encountered a case of leiomyosarcoma of the penis in a 45 year old man. On staging work up. local invasion to corpus cavernosum. but no evidence of lymph node metastasis was evident. After the confirmation of leiomyosarcoma by excisional biopsy, the patient underwent partial penectemy. Herein we report this case with the review of literatures.

OBJECTIVES: The purpose of this study is to investigate the characteristics of drinking patterns and the prevalence of hazardous drinking and alcohol use disorder with the assessment of alcohol policy needs in community population of urban city in Korea. METHODS: Data was collected from 1,000 residents in a single urban city in Korea, from June 1 to July 31, 2011 by a questionnaire. As research tools, socio-demographic characteristics composed of variables based on study purpose, alcohol problems and alcohol use disorder state scales composed with Alcohol Use Disorder Identification Test(AUDIT) and Cut down, Annoyed, Guilty, Eye-opener(CAGE), and the assessment of alcohol policy needs in community population questions were used. RESULTS: The lifetime experience of alcohol drinking was 97.4%. For the frequency of drinking, 21.9% of population responded 2 to 4 times per weekly. 24.4% of male had one time or more high risk drinking, defined as having four or more drinks in a sitting, per week. 51.6% experienced the first time drinking of alcohol in adolescence. The lifetime prevalence of hazardous drinking and alcohol use disorder were 14.9% and 3.3%, respectively using AUDIT. Alcohol use disorder were 9.6% with the CAGE scale. Problem drinking were 8.4% in this study. They requested the program such as prevention education(57.2%), construction of liaison system to treatment facilities( 50.1%), alcohol counseling and intervention(41.7%), and rehabilitation program(39.8%). CONCLUSIONS: These results demonstrate that alcohol problem and alcohol use disorder were much prevalent, and these problem started in the earlier age. It is necessary to develop an effective alcohol prevention program or policy with considering the needs in community population.
