Some sexual differentiation disorders are associated with gonadal neoplasia and increased incidence of testicular tumors has been discribed in the patients with, XY gonadal dysgenesis. The incidence of testicular tumors in infants and children are rare, representing only 1% of all pediatric solid tumors. In general, gonadal stromal tumors are one of the most characteristic endocrine tumors of the testis, endocrine activity occurs in at least 10-20%, among them Leydig cell tumors and Sertoli cell tumors are clinically important. Although the exact pathogenesis is unknown, endocrine activity due to estrogen secretion can be manifested clinically with gynecomastia or precocious puberty. We experienced and reported a child who visited for sexual precocity and had XY gonadal dysgenesis with Sertoli cell tumor.

PURPOSE: The cause and pathogenesis of lower urinary tract symptoms (LUTS) in elderly men is unclear. We analyzed the clinical and urodynamic findings of elderly patients with LUTS to search for accurate diagnosis and effective treatments. MATERIALS AND METHODS: We performed a retrospective chart review of 154 male patients older than 65 years old with LUTS who underwent urodynamic studies between January 2002 and December 2008. The patients were divided into irritative and obstructive symptom groups according to their chief complaints. The urodynamic findings between two groups were compared. And the prevalence of detrusor dysfunction (either detrusor underactivity; DU or detrusor overactivity; DO) according to age, history of urinary retention, the presence of an indwelling urethral catheter, neurologic disease, or diabetes was estimated. RESULTS: The mean age of men was 70.8+/-4.5 years. On urodynamics, detrusor dysfunction was detected in 116 (75.4%) of 154 patients. Seventy eight (50.6%) patients showed demonstrable evidence of DU of whom 33 (21.4%) had concomitant DO, while 18 (11.7%) had concomitant bladder outlet obstruction (BOO). BOO and DO was identified in 67 (43.5%) and 71 (46.1%) patients, respectively. The prevalence of was significantly greater in the presence of history of acute urinary retention and an indwelling urethral catheter. CONCLUSION: One hundred forty one (91.6%) elderly patients with LUTS showed urodynamic abnormalities such DO, DU and BOO. Urodynamic study would play a important role in establishing a correct diagnosis in elderly patients with LUTS and deciding on additional treatments.

To evaluate the role of capsular polysaccharide (CPS) as a virulence factor, the interaction of V. vulnificus with mouse peritoneal macrophages and serum, which are involved in the clearance of bacteria from blood and other tissues, were examined. In this study, MO6-24/0 (wild strain; hemolysin- and capsule-positive), MO6-24/I' (acapsular spontaneous mutant), CVD 752 (acapsular transposon mutant), and CVD 707 (hemolysin-negative and capsule-positive mutant) were used. The strain with CPS (MO6-24/0 and CVD 707) were more resistant to phagocytosis by mouse peritoneal macrophages compared with acapsular strains (MO6-24/T and CVD 752), and the resistance to phagocytosis was not changed by serum opsonin in the capsular strains. Acapsular strains were more susceptible to serum bactericidal activity than the capsular strains through the classical complement pathway. MO6-24/0 strain were detected in blood, spleen, liver and lung at 4 hours after intraperitoneally infection, whereas CVD 752 were not detected. All tested strains could induced the transcription of inflammatory cytokine gene such as IL-1, IL-6, IL-10 and TNF-u, and their inductions were not decreased by cytochalasin B treatment. This results demonstrate that CPS of V. vulnificus plays an important role in V. vulnificus infection through interfering nonspecific host defense system such as blood clearance and phagocytosis.

Carotid body tumor is uncommon and has been a source of fear and curiosity to the surgeon for many years. This puzzling tumor attaches itself so intimately to the carotid artery system that its routine removal is often associated with serious consequences. The justification for its extirpation has been debated vigorously. Recently, we have experienced a case of carotid body tumor and obtained good result after total removal. We report our case with a brief review of the articles.

We report here on a case of priapism that was associated with the use of tadalafil. A 41 year-old-man visited our urology outpatient department with a relapsed erection he'd experienced for 3 days. He had no contributing factors for the priapism. He had taken tadalafil, which was prescribed at a local medical center 3 days previously. After the development of priapism, he first visited the emergency department of other hospital. Aspiration was done and then the priapism was resolved. Yet the priapism recurred 2 days later, andaspiration and other bedside management failed to resolve it. After his arrival to our department, weimmediately performed a caverno-glandular shunt with 18-gauge needle and we observed bright reddish- color blood. An intracorporal ephedrine injection and saline irrigation were then done. After that, the patient gradually experienced detumescence. The priapism did not recur during the 2 days of the hospitalization period. At the outpatient follow-up of 3 months later, patient almost recovered to his full erectile function and he had normal sexual activity.

In this case study, we investigated the effects of robot-assisted gait training on the plasticity of motor system in a stroke patient using functional MRI. A patient who suffered from the left hemiparesis following the right MCA infarction performed gait training with a robot-assisted gait orthosis. Before and after gait training, motor performances were assessed and functional MRIs were acquired with motor activation task of affected lower limb. After gait training with a robot-assisted orthosis, the patient's motor performances were improved and cortical activities were changed. Activation in the ipsilesional primary sensorimotor cortex was increased and cortical reorganization was induced in a way that nearby regions were recruited for the movement of affected lower limb. The results of this study showed that gait training with a robot-assisted orthosis induced cortical reorganization of the motor network that resulted in enhancement of motor performance of the lower limb.

Eosinophilic gastroenteritis (EG) is characterized by eosinophilic infiltration of the bowel wall and variable gastrointestinal manifestations. Clinicians should have a high index of suspicion for EG when faced with gastrointestinal symptoms and peripheral eosinophilia to avoid incorrect diagnosis and inappropriate treatments. A 24-year-old woman was admitted to our hospital complaining of acute right lower quadrant abdominal pain and a laparoscopic appendectomy performed for a presumed diagnosis of an acute appendicitis. However, the procedure revealed bowel edema and a moderate amount of ascites without evidence of a suppurative appendicitis. Postoperatively, she showed persistent and progressive eosinophilia, exudative eosinophilic ascites, eosinophilic infiltration of the resected appendix wall, and eosinophilic infiltration of gastroduodenal mucosa. A punch biopsy of the abdominal skin also revealed inflammation with marked eosinophilic infiltration of the skin. She recovered after the treatment with a low dose of steroid for the EG with eosinophilic dermatitis. EG with eosinophilic dermatitis has not been reported yet and is considered fortuitous in this case.
