Neonatal hydrometrocolpos is the cystic dilatation of the vagina and uterus, which is caused by the combination of vaginal obstruction such as imperforate hymen, transverse vaginal septum, or vaginal atresia, and glandular secretion by maternal estrogenic stimulation. Although hydrometrocolpos is a rare congenital abnormality unlike pubertal hematocolpos, it is one of the relatively common abdominal masses in neonates. In typical cases the diagnosis may be determined easily by the combination of a pelvic mass, upper urinary tract dilatation and a bulging membrane in the vaginal introitus. The presense of a lower abdominal mass in a female infant should always arouse suspicion of hydrometrocolpos and lead to careful examination of the vagina. We report a case of neonatal hydrometrocolpos due to imperforate hymen which was initially presented as a large abdominal mass and a bulging membrane in the vaginal introitus. For 72 hrs, the abdominal mass increased rapidly, accompanied by urinary tract obstruction. It was relieved by a simple incision of the imperforate hymen and drainage of 300 cc of whitish mucoid vaginal fluid, and by Foley catheter drainage of 750 cc urine. No other anomaly was observed.

PURPOSE: Gene therapy, stem cell therapy, and low-energy extracorporeal shockwave therapy (ESWT) have been investigated as treatments for refractory erectile dysfunction (ED), but inconclusive evidence has been obtained. We investigated the effect of a next-generation electromagnetic cylinder ESWT device on an animal model of ED. MATERIALS AND METHODS: Diabetes mellitus (DM)-induced rats were divided into 3 groups: group 1, control; group 2, DM; and group 3, DM+ESWT. Rats were treated with ESWT 3 times a week for 2 weeks. After the treatment course, intracavernous pressure was measured and the corpus cavernosum and cavernous nerve were evaluated. RESULTS: In the DM group, all parameters predicted to be significantly lower in the ED model had statistically significantly decreased (p < 0.01). As a measurement of erectile function, intracavernous pressure was evaluated. The DM+ESWT group exhibited significantly restored erectile function compared to the DM group (p < 0.05). Moreover, ESWT treatment restored smooth muscle content, as assessed by Masson's trichrome staining (p < 0.05). Finally, corporal tissue and the dorsal nerve were evaluated by immunohistochemistry, Western blotting, and ELISA. After ESWT treatment, vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), platelet endothelial cell adhesion molecule-1, cyclic guanosine monophosphate, and neuronal nitric oxide synthase (nNOS) expression levels were restored to levels in the DM group (p < 0.05). CONCLUSIONS: Electromagnetic cylinder ESWT device resulted in increased VEGF, nNOS, and eNOS expression; reduced smooth muscle atrophy; and increased endothelial cell regeneration in a DM-associated ED model. Our data suggest that safe and effective application could be possible in future clinical studies.

PURPOSE: Testosterone replacement therapy is an effective treatment for late-onset hypogonadism (LOH) despite a few contraindications and side-effects. The aim of this study was to determine whether modified Ojayeonjonghwan (KH-204, Korean herbal formula) improved LOH. KH-204 is a strong antioxidant herbal formula. We evaluated the effect of Korean herbal prescription on androgen receptor (AR) expression in an aged rat model of LOH. MATERIALS AND METHODS: Eighteen-month-old rats were used as aged LOH rat models. Eighteen Sprague-Dawley rats were randomly divided into three equal groups of six animals each and treated with one of the following: 1) normal control group (oral administration with distilled water, n=6), 2) KH-204 200 group (oral administration with 200 mg/kg of KH-204, n=6), and 3) KH-204 400 group (oral administration with 400 mg/kg of KH-204, n=6). After four weeks of treatment (once daily, distilled water or KH-204), serum testosterone levels, changes in testicular and epididymal weight, Western blotting analysis of AR expression and measurement of oxidative stress were examined. RESULTS: Treatment with the herbal formulation KH-204 200 mg/kg and 400 mg/kg (1) increased the weights of testis and epididymis; (2) increased the level of serum testosterone; (3) increased the level of superoxide dismutase and reduced the level of 8-hydroxy-20-deoxyguanosine; and (4) upregulated AR expression in testicular tissue. CONCLUSIONS: KH-204 might be an effective alternative for LOH. It improves antioxidant mechanisms and increases testicular AR expression without side-effects.

BACKGROUND: Surgical site infection (SSI) is prominent among the total incidence of healthcare-associated infections, and is a major contributing factor in the trend of increasing medical costs. There have been numerous efforts to analyze the conditions and causes of SSI for the purpose of prevention. In this study of SSI development after gastric surgery, we evaluated the prevalence of specific pathogens and compared the clinical characteristics observed between gram-positive (GPB) and gram-negative bacteria (GNB). MATERIALS AND METHODS: We conducted a retrospective study of patients who developed SSI within 30 days after gastric surgery at 13 clinics in Korea, between January 2007 and December 2008. Only those cases of SSI which included confirmed pathogen were included in this study. RESULTS: Among the 121 patients who developed SSI, GPB were observed in 32 patients and 36 cases, and GNB were isolated in 32 patients and 36 cases. Methicillin resistant Staphylococcus aureus (MRSA) was the most frequently isolated pathogen in this analysis. There were no differences observed between the GPB and GNB group in terms of baseline characteristics, patient or procedure related risk factors, or factors associated with prophylactic antibiotics. CONCLUSIONS: In the previous studies of the occurrence of SSI after gastric surgery, it was reported that the majority of observed pathogens were enteric GNB. Further studies of the incidence of SSI after gastric surgery, particularly those related to MRSA infection, are necessary.
