Idiopathic ureteropelvic junction stricture is not an uncommon disorder with resultant hydronephrosis of affecting kidney, and most frequently encountered in infant and children. Multiple causes of stricture have been identified. Abnormal organization of smooth muscle bundles at the ureteropelvic junction has been reported, and electron microscopy has demonstrated excessive collagen deposition within the intramural stroma. However, the exact cause of obstruction of UPJ stricture is uncertain. We reviewed 23 cases with idiopathic hydronephrosis underwent dismembered pyeloplasty. Examination of strictured segment with light the normal interwoven pattern, were arranged into an abundant outer circular and an inner longitudinal layer in 21 of 23 cases. But muscle thickness was not changed, and collagen was normal in both amount and arrangement. This results suggested that the abnormal muscle arrangement at the ureteropelvic junction might be the cause of the idiopathic stricture.

Ureteropelvic junction obstruction is one of the most common problems requiring surgical correction in children. Glomerular development, which continues at birth, may interfered with by obstruction. So the recognition and correction of ureteropelvic Junction obstruction at this early age are important. Fortunately, to date, the widespread use of maternal ultrasound has led to an increase in the detection of fetal obstructive uropathy. The operative technique varied according to the nature and severity of the abnormality, but the dismembered pyeloplasty that resect the adynamic segment completely is favored and very successful. We reported 17 cases underwent dismembered pyeloplasty in children due to severe hydronephrosis (over Grade IV) secondary to UPJ stricture, and obtained satisfactory results. Nephrostomy drainage of the kidney was used in l3 cases, and duration was within 2 weeks in most cases. Ureteral stent was used only in 4 cases associated with severe infection or repeated pyeloplasty. In 13 cases followed up over 3 months (Mean: 16 months), the good result was in 11 cases (84.6%) and fair in 2 cases(l5.4%).

Bilateral renal cell carcinoma is very rare and represents a challenge to the clinician. In the past, bilateral renal cell carcinoma indicated a poor prognosis. But recent, aggressive operative intervention with 'nephron-salvaging procedure' can improve the survival of bilateral renal cell carcinoma. We experienced two cases of bilateral renal cell carcinoma; the former was multicystic nature, well-differentiated bilateral renal cell carcinoma and the later was found incidentally during cadaver donor transplantation due to brain tumor, and it was documented Von-Hippel-Lindau`s syndrome on autopsy.

Malignant hyperthermia is a potentially fatal hypermetabolic syndrome characterised by hyperpyrexia and skeletal muscle rigidity. It can be induced by all of the currently used inhalation anesthetics or by injection of succinylcholine. A case of malignant hyperthermia was experienced which developed 80 minute after induction of general anesthesia with thiopental sodium, suecinylcholine, halothane, N2O and O2. One and half hours after induction, arrhythmia developed and was followed by unstable blood pressure, hyperpyrexia and muscle rigidity. Anesthesia was terminated and vigorous emergency treatment and dantrolene were administered. The patient recovered normal body temperature and consciousness, but expired about 4 days after induction because of late complication including disseminated intravascular coaggulation. The etiologic factor, clinieal feature, treatment and prevention of Malignant hyperthermia are discussed.

Emphysematous pyelonephritis is a rare, life-endangering suppurative infection of the renal parenchyma and perirenal tissues. The disease is encountered mainly in the diabetic patient with or without ureteral obstruction and is characterized by the production of intrarenal and occasionally, perirenal gas. We report a case of emphysematous pyelonephritis, treated by left nephrectomy, in 55-year-old diabetic woman.

Takayasu's arteritis is generally recognized as a chronic, idiopathic, inflammatory disease, which affects the aorta and the proximal portions of its major branches. We experienced a patient with Takayasu's arteritis who was presented with main pulmonary artery stenosis and right coronary ostial occlusion without involvement of aorta nor its major branches. She was managed with pulmonary arterioplasty and coronary artery bypass graft. This case emphasize that the disease cannot affect the aorta.

Adeno-associated virus (AAV) and human papillomavirus (HPV) DNAs were found in abnormal quality semen, early abortus and female genital tissues. It was suggested that they might cause male infertility and miscarriages. This study was performed to determine the detection rate of these viruses in the semen and to assess the relationship between the presence of virus and male factor infertility and recurrent miscarriages. Sixty-three of 99 recruited male were included in this study according to the completeness of follow-up and the sample availability. Fourteen male with normal reproductive capacity were allocated to control group, 15 male with abnormal results in semen analysis were grouped as male factor infertility (MF) group, and 34 male whose spouses have had history of repeated spontaneous abortions were designated as repeated miscarriage (RM) group. AAV and HPV were detected in semen by polymerase chain reaction. The detection rate of AAV in the MF infertility group and RM group was 60.0% and 50.0%, respectively, while 14.3% in the control group (p < 0.05). However, the differences in the detection rate of HPV were not statistically significant among groups. These results suggest that AAV could be related to repeated miscarriages and male infertility.

This study was conducted to evaluate the influence of alcohol consumption on the risk of ocular trauma. We retrospectively reviewed the medical records of 1,024 patients who visited emergency department and received ophthalmologic examination from January 1 to December 31, 2009. The patients were divided into 2 groups: those with ocular trauma (n = 494) and those without (n = 530); the influence of alcohol consumption was compared between these 2 groups. In the ocular trauma group, the association of the causes and types of ocular trauma with alcohol consumption was evaluated. One of 530 patients of no trauma group and 117 (23.7%) of 494 patients of trauma group were related with alcohol intake, and the difference was statistically significant (P < 0.001). Concerning the causes, physical assault was significantly more common in alcohol-associated injury (P < 0.001). Regarding the types of injury, orbital wall fracture and hyphema showed a significant association with alcohol consumption (P < 0.001). Older age and nighttime injury were significantly related to the increased risk of alcohol-associated ocular trauma (P = 0.018 and < 0.001, respectively). In conclusion, alcohol consumption significantly increases the risk of ocular trauma.

Atrial septal aneurysm (ASA) was reported as a cause of unknown origin of central or peripheral thromboembolism with patent foramen ovale, aortic debris and spontaneous echo contrast. Especially the paradoxical right to left shunt via micro-fenestration on this sac may be the important cause of this embolism. We report a case of 39 year-old female patient who had atrial septal aneurysm with multiple renal infarction. Symptom was improved with aneurysmectomy and patch closure, then long term anticoagulation has been continued.

Osteogenesis imperfecta is one of the groups of hereditary disorders of connective tissue which includes the Ehlers-Danlos syndrome, the Marfan syndrome, pseudoxanthoma elasticum, and Hurler syndrome. While cardiovascular involvement is associated with each of these disorders, it is least common in osteogenesis imperfecta and is overshadowed by the bony, ocular, otologic, cutaneous, and dental manifestations that are characteristic of the disorder. In evaluating patients with osteogenesis imperfecta, careful attention should be paid to cardiovascular findings and if valvular lesions are noted, patients should be instructed regarding the need for antibiotic prophylaxis for dental and surgical procedures. We report a case of osteogenesis imperfecta associated with aortic regurgitation.
