PURPOSE: Urethrocutaneous fistulas and urethral strictures are the most frequent complications after hypospadias repair. We reviewed outcomes after surgical repair of these complications to evaluate the factors determining successful outcome. MATERIALS AND METHODS: In 60 patients with fistula or stricture after hypospadias repair performed between September 1993 and January 2008, we reviewed incidences, clinical features, and outcome after repair with respect to initial hypospadias types. RESULTS: Fistulas were observed in 42 patients and were surgically repaired in 39 (92.8%). In 8 (19.0%) and 3 (7.1%) patients, concurrent meatal and urethral strictures were noted, respectively. The number of fistulas was single in 38 (90.5%) and 2 in 4 (9.5%) patients. Fistulas occurred most frequently from the penoscrotal type hypospadias (22/65, 33.8%) and had initially undergone transverse preputial island flap repair (13/26, 50%). Complete excision of the fistulous tract and multilayer advancement flap closure was the most common method for fistula repair (24), followed by cross-suture in 9 and repeat urethroplasty in 6. Initial management was successful in 35 (89.7%) patients. Urethral strictures were observed in 16 patients with equal incidences at the meatus and the other portion of the urethra. Successful outcome was achieved in all metal stenosis after repeat meatoplasty, whereas for urethral strictures, 4 (20%) patients who underwent visual urethrotomy experienced recurrent strictures. CONCLUSIONS: Urethrocutaneous fistulas can be successfully repaired by complete excision and cross-suture closure and multiple coverage with healthy tissues. In urethral strictures, reconstruction of ample neo-meatus is the key to achieving sufficient stream regardless of the stricture site.

We have experienced 2 patients with dorsally migrated sequestrated lumbar disc herniation with cauda equina syndrome and obtained a complete motor and sensory recovery after early decompressive laminectomy and discectomy with or without fusion in all cases. The purpose of this paper is to report two unusual cases of lumbar disc herniation that we experienced, and to emphasize the importance of early decompressive surgery for the treatment of cauda equina syndrome accompanied with dorsally migrated sequestrated lumbar disc herniation.

In the mid 1980's, the ITA(internal thoracic artery) graft was clearly recognized to be superior to the sapheonous vein graft in respect to long term patency. Therefore, there has been growing interest in the arterial conduit with the possibility of improving the long term result. We have been performing CABG with GEA since 1998 with the same purpose. For mid-term and long-term follow up, we have been performing postoperative coronary angiography. In this paper, a case of GEA spasm, a purported drawback of this conduit, during postoperative coronary anigiography and relieved by direct infusion of 200 microgram isoket into the GEA is reported. The current case which exemplifies the spastic nature of RGEA is accompanied with coronary angiography.

PURPOSE: We mapped the location of prostate cancer in Korean men, and investigated the volume and tumor distribution in relation to clinicopathological variables. MATERIALS AND METHODS: The volume of cancer and the anatomic location of each tumor foci were determined from 186 radical prostatectomy specimens, which were digitized to fit into a prototype prostate model. Using the computer-based digital images, the zonal cancer volume and distributional frequency were analyzed with respect to the clinical and pathological parameters, which were demonstrated in gray scales. RESULTS: The preoperative serum prostate-specific antigen (PSA) level ranged from 2.0 to 38.9ng/ml. The mean cancer volume of the 186 specimens was 4.5ml (median 1.9ml, range 0.01-37.7). The impalpable cancers were located more anteriorly and in the transition zone, and were also were smaller in volume (2.7ml vs. 5.5ml, p=0.004) than the palpable cancers. Cancers with seminal vesicle invasion were located more medially in the peripheral zone, and were larger in volume than organ-confined cancers or cancers with extracapsular extension (13.2ml vs. 3.0ml, p<0.001). For Gleason scores of 2-6, 7, and 8-10, the mean cancer volumes were 2.2, 3.7 and 8.2ml, respectively (p<0.001). High grade cancers were located more medially in the peripheral zone, especially when approaching the apex. CONCLUSIONS: T1c cancers are located more anteriorly and in the transition zone; therefore, inclusion of these areas for targeted biopsy may help to improve the detection of cancer in patients with elevated PSA levels and impalpable prostate cancer. A medial location of seminal vesicle invasive cancers may imply an ejaculatory ducts route of invasion rather than a direct extracapsular extension.

T cell mediated immunity amlifies macrophage capacities to kill and digest the bacilli through production of interferon-gamma (IFN-gamma). The secreted cytokines of Th1 and Th2 cells can mutually regulate and inhibit each other's function. Therefore, the fine balance between the secreted cytokines is important for the resulting nature of tuberculosis. In this study, activation marker and cytokine production profiles were compared in patients with active tuberculosis and healthy control, and according to degree of radiographic extent and pleural involvement. METHOD:Forty-four patients with active pulmonary tuberculosis and 25 normal controls were recruited. We measuerd soluble interleukin-2 receptor(sIL-2R), IFN-r, IL-4 and IL-5 produced from blood mononuclear cells in vitro stimulation with phytohemagglutinin by ELISA. RESULTS: The sIL-2R and IFN-gamma from patients with active pulmonary tuberculosis were significantly lower than normal control, while IL-4 and IL-5 were not different between two group. The sIL-2R and IFN-r decreased in proportion to the extent of pulmonary involvement, and the sIL-2R and IFN-r from pulmonary tuberculosis with pleural effusion were significantly lower than those without pleural effusion. CONCLUSION: At the level of systemic T cells, development of tuberculosis is associated with diminished Th1 but not enhanced Th2 response.

OBJECTIVE: To evaluate the depiction rate and morphologic features of myocardial bridging (MB) of the left anterior descending coronary artery (LAD) using dual-source CT (DSCT). MATERIALS AND METHODS: CT scans from a total of 1,353 patients who underwent DSCT were reviewed retrospectively for LAD-MB. Seventy-eight patients were excluded due to poor image quality or poor enhancement of the coronary artery. The length and depth of the MB were analyzed and classified as superficial or deep with respect to the depth (< or = 1 or > 1 mm) of the LAD tunneled segment. Superficial MB was subdivided into complete or incomplete types according to full or partial encasement of the myocardium. RESULTS: Of the 1,275 patients included in this study, 557 cases of MB were found from 536 patients (42%). Superficial MB was observed in 368 of 557 (66%) cases, and deep MB was seen in 189 of 557 (34%) cases. Superficial MB showed 2 types: complete (128 of 368, 35%) and incomplete (240 of 368, 65%). The mean length of a tunneled segment for superficial MB was 16.4 +/- 8.6 mm. The mean length and depth of a tunneled segment for deep MB were 27.6 +/- 12.8 mm and 3.0 +/- 1.4 mm, respectively. The incidence of atherosclerotic plaques in a 2-cm-long segment proximal to MB was 16%. CONCLUSION: The depiction rate of LAD-MB using DSCT in a large series of patients was 42%, with two-thirds of MB segments being the superficial type.

Many neoplasms, including lung cancer, breast cancer, melanoma, and gastrointestinal tract malignancy, possess potential for skin metastasis. Skin metastases can represent the first presentation of such malignancies and may be observed incidentally during routine exam. Skin metastases from gastric adenocarcinoma are uncommon, with a prevalence rate of 0.04-0.8%. Cutaneous metastases from gastric cancer are generally observed as the initial symptom of advanced gastric cancer. Early detection and treatment can increase patient survival. A 42-year-old woman visited our department with nodule about 1 cm in size on the right frontal scalp noticed incidentally after laparoscopy-assisted distal gastrectomy and adjuvant systemic chemotherapy for early gastric cancer about 16 months prior. The patient was diagnosed with skin metastasis from gastric adenocarcinoma. Complete excision of the skin lesion and additional chemotherapy were performed. Herein, we report a case of nodular tumor-like scalp metastasis from early gastric cancer with a brief review of the literature.

BACKGROUND: Immunologic and inflammatory responses of cardiopulmonary bypass(CPB) influence postoperative mortality and morbidity with multiple organ injury. It has been reported that ischemia/reperfusion induced-myocardial injury during CPB is causative of release of inflammatory cytokines such as interleukin-6(IL-6) and tumor necrosis factor-alpha (TNF-alpha). The purpose of this study was to detect the time course of the activated cytokine and troponin-T(TnT), and to examine the correlation between such parameters during CPB. MATERIAL AND METHOD: The serial samples were collected from arterial blood via radial arterial catheter in 23 patients who are underwent open heart surgery (OHS) with CPB, the IL-6, TNF-alpha and TnT were checked. RESULT: (1) IL-6, TNFalpha- and TnT concentration increased significantly during CPB with a peaking level of CPB-off (p 0.05). (2) IL-6 had highly positive correlation with aortic cross clamping time and total bypass time(r=0.80, 0.78; p 0.05, respectively). (3) There was no correlation among IL-6, TNF-alpha and TnT. CONCLUSION: In conclusion, these data showed that elevated production of serum IL-6 during CPB was attributable to ischemia/reperfusion induced-myocardial damage. IL-6 will become a new and sensitive biological marker in assessment of myocardial damage during OHS with CPB. However, further studies will be needed to apply IL-6 in more patient population.
