PURPOSE: The incidence of overactive bladder (OAB) and the efficacy of alpha blocker and tolterodine combination therapy were examined in patients with symptomatic benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Between March 2001 and December 2001, 144 BPH patients were subdivided into those with BPH, or BPH with OAB, based on urodynamic studies. All patients were treated with alpha blockers for 3 months. Patients with no symptomatic improvement were treated with alpha blockers and tolterodine for 2 months. An increase in the International prostate symptom scores (IPSS) of more than 3 points after medication was considered an improvement, but if not, as a failure. RESULTS: Of the 144 patients, 76 (53%) had BPH and 68 (47%) had BPH with OAB. The patients with BPH and OAB were older (p<0.05), but no differences were observed in the serum creatinine, IPSS, prostate volume, maximum flow rate or post-void residual urine (PVR) between the 2 groups. After 3 months treatment with alpha blockers, 79% (60/76) of the BPH and 35% (24/68) of the BPH with OAB patients had improved (p<0.05). Of the patients showing no improvement, 38% (6/16) with BPH and 73% (32/44) with BPH and OAB showed improvement after the addition of tolterodine. CONCLUSIONS: The combination therapy was more effective than alpha blockers alone in the treatment of patients with coexisting BPH and OAB. We recommend identifying these patients with an initial urodynamic study, which allows for the appropriate management and identification of those patients that may benefit from a more invasive treatment.

An epidermal cyst, presenting as an intrascrotal tumor, with no relation to the testicles or cord structures, is a rare benign tumor. Their etiology is unknown, but the most widely accepted theory on the histogenesis of testicular epidermal cysts is that they are the end result of a monolayer teratoma arising from germ cells; however, an extratesticular epidermoid cyst is believed to be an abnormal closure of the median raphe and urethral groove. An extratesticular epidermal cyst is normally subcutaneous, and can be localized anywhere along the median raphe, from the distal penis to the anus. To our knowledge, there has been no case reported in the Korean literature. A case of an intrascrotal epidermal cyst is reported in a 44-year-old man.

Herein, a new left renal vein stenting procedure (expandable metallic stent placement), which provided relief for an 18-year-old man incapacitated by an intermittent gross hematuria, is reported. The placement of an expandable metallic stent is a minimally invasive therapy, and a simpler and more physiological therapy than previous approaches to Nutcracker syndrome.

Supernumerary kidney is one of the very rare anomalies of the urinary tract. Only about 75 cases have been reported since it was first described in 1656. Herein we present a case of supernumerary kidney which was diagnosed by ultrasonography, intravenous urography and CT scanning.

PURPOSE: To evaluate the cysticidal effect of 5 kinds of commercially available contact lens disinfectants against 2 clinical isolates of Acanthamoeba. METHODS: Five kinds of commercially available contact lens disinfectants were soaked with cysts of Acanthamoeba ludgdunesis and castellanii at the concentration of 10(3), 10(4), and 10(5) cells/ml for 1 and 4 or 6 hours. Cysts which were not excysted in 7 days after treatment were recognized to be killed. Morphologic changes were evaluated by electron microscopic observation. RESULTS: Contact lens disinfectants which contain myristamidopropyl dimethylamine (MAPD) showed the best cysticidal effect. These disinfectants demonstrated a cysticidal effect on both Acanthamoeba species of all concentrations in 6-hour treatment. Contact lens disinfectants which contain polyhexamethylene biguanide (PHMB) did not demonstrate cysticidal effect, except for Acanthamoeba castellanii at the concentration of 10(3) cells/ml, in either 4- or 6-hour treatment. Separation of plasma membrane from endocyst and damage of organelles were prominent in cases showing a cysticidal effect. CONCLUSIONS: Contact lens disinfectant which contains MAPD may be helpful in preventing the Acanthamoeba keratitis. A higher concentration of PHMB is required to be effective in preventing Acanthamoeba keratitis.

BACKGROUND: Reactive oxygen species (ROS) are known to be related to cardiovascular diseases. Many studies have demonstrated that angiotensin-converting enzyme inhibitors have beneficial effects against ROS. We investigated the antioxidant effect of captopril and enalapril in nitric oxide mediated vascular endothelium-dependent relaxations. MATERIALS AND METHODS: Isolated rabbit abdominal aorta ring segments were exposed to ROS by electrolysis of the organ bath medium (Krebs-Henseleit solution) after pretreatment with various concentrations (range, 10-5 to 3x10-4 M) of captopril and enalapril. Before and after electrolysis, the endothelial function was measured by preconstricting the vessels with norepinephrine (10-6 M) followed by the cumulative addition of acetylcholine (range, 3x10-8 to 10-6 M). The relevance of the superoxide anion and hydrogen peroxide scavenging effect of captopril and enalapril was investigated using additional pretreatments of diethyldithiocarbamate (DETCA, 0.5 mM), an inhibitor of Cu/Zn superoxide dismutase, and 3-amino-1,2,4-triazole (3AT, 50 mM), an inhibitor of catalase. RESULTS: Both captopril and enalapril preserved vascular endothelium-dependent relaxation after exposure to ROS in a dose-dependent manner (p<0.0001). Pretreatment with DETCA attenuated the antioxidant effect of captopril and enalapril (p<0.0001), but pretreatment with 3AT did not have an effect. CONCLUSION: Both captopril and enalapril protect endothelium against ROS in a dose-dependent fashion in isolated rabbit abdominal aortas. This protective effect is related to superoxide anion scavenging.

Case reports after accidental subdural injection during attempted epidural block have usually described extensive neuraxial blocks with a characteristic radiographic appearance on contrast injection. We experienced a case of cervical subdural injection with unusual clinical findings and radiographic appearance. A 51-year-old female patient with central herniated nucleus pulposus at cervical (C5/6) and lumbar level (L4/5, L5/S1) was referred to the pain clinic. During attempted cervical epidural block at the C6/7 interspace with fluoroscopy, injection of the 4 ml contrast showed posterior spread at cervical level. After cervical epidural steroid injection, the contrast was also confined to the posterior aspect of the spinal canal at lumbar level with fluoroscopy. In order to discriminate subdural space from epidural space, we performed transforaminal epidural injection of the 2 ml contrast at the L5/S1 interspace and we could confirm cervical epidural injection was made into the subdural space. We discuss the clinical characteristics of a subdural injection and the appearance of the cervical and lumbar subdurogram.

BACKGROUND: To evaluate the effectiveness of minimally invasive surgery total hip arthroplasty (THA) using the two-incision technique as described by Mears. METHODS: From January 2003 to December 2006, sixty-four patients underwent total hip arthroplasty using the one-incision (group I) and two-incision (group II) technique by one surgeon. There were 34 hips in group I and 30 hips in group II. There was no difference in age, gender, and causes of THA between the two groups. We evaluated the operation time, bleeding amount, incision length, ambulation, hospital stay, and complications between the two groups. RESULTS: There was no difference in the bleeding amount between the two groups. Operation time was longer in the two-incision group than in the one-incision group. Operation time of the two-incision technique could be reduced after 15 cases. Patients started ambulation after surgery earlier in group II than group I, and the hospital stay was shorter in group II than in group I. There was no difference in clinical results between the two groups. There was no difference in component position of the acetabular cup and femoral stem between the two groups. Intraoperative periprosthetic fracture occurred in four cases (13.3%) in group II. CONCLUSIONS: Two-incision THA has the advantage of rapid recovery and shorter hospital stay. However, longer operation time and a high complication rate compared to one-incision are problems that need to be solved in the two-incision technique.
