[Show abstract][Hide abstract] ABSTRACT: Purpose
The purpose of this study was to compare prostate volume measured by transrectal ultrasonography (TRUS) between transaxial scanning and midsagittal scanning. We tried to determine which method is superior.
Materials and Methods
A total of 968 patients who underwent TRUS for diagnosis of any diseases related to the prostate were included in this study. When measuring prostate volume by TRUS, we conducted the measurements two ways at the same time in all patients: by use of height obtained by transaxial scanning and by use of height obtained by midsagittal scanning. Prostate volume was calculated by using the ellipsoid formula ([height×length×width]×π/6).
For prostate volume measured by TRUS, a paired t-test revealed a significant difference between using height obtained by transaxial scanning and that obtained by midsagittal scanning in all patients (28.5±10.1 g vs. 28.7±9.9 g, respectively, p=0.004). However, there were no significant differences in the prevalence of prostate volume more than 20 g (known benign prostatic enlargement [BPE]) between the two methods by chi-square test (90.5% [n=876], 90.8% [n=879], respectively; p=0.876). When analyzed in the same way, there were no significant differences in the prevalence of prostate volume more than 30 g (generally, high-risk BPE) between the two methods (34.5% [n=334], 36.3% [n=351], respectively; p=0.447).
Although prostate volume by TRUS differed according to the method used to measure height, that is, transaxial or midsagittal scanning, we conclude that there are no problems in diagnosing BPE clinically by use of either of the two methods.

[Show abstract][Hide abstract] ABSTRACT: Despite successful hypospadias repair surgery, complications may occur. We report on a case of recurrent urinary tract infection from urethral stricture and urethral hair growth after hypospadias repair surgery. A 33-year-old man who first underwent hypospadias repair surgery at the age of seven underwent two more visual internal urethrotomy operations afterward. He was referred to our hospital because of voiding difficulty, dysuria, and residual urine sense. His urethral meatus was located at 1 cm proximal ventral sulcus from the glans. We found the urethral stricture and one hair in the urethra at the 2 cm proximal portion from the urethral meatus by retrograde urethrography and urethroscopy. Bacteriuria was found on urine culture, thus, we resolved the problems with soundation, epilation, and antibiotic therapy. However, the patient kept experiencing these problems recurrently; therefore, we managed his problems by recurrent urethral soundation, hair epilation, and antibiotic treatment with three years of regular follow-up.
[Show abstract][Hide abstract] ABSTRACT: In the development of solvent-free offset ink, the roles of resin molecular weight and used solvent on the ink performance were evaluated by examining the relationship between the various properties of resin and solvent and print quality. To find the best performing resin, the soy-oil fatty acid methyl ester (FAME) was applied to the five modified-phenolic resins having different molecular weights. It is found from the experimental results that the ink made of higher molecular weight and better solubility resin gives better printability and print quality. It is because larger molecular weight resin with better solubility gives higher rate of ink transfer. From the ink application of different esters to high molecular weight resin, the best printing performance was yielded from the soy-oil fatty acid butyl ester (FABE). It is due to its high kinematic viscosity resulting in the smallest change of ink transfer weight upon multiple number of printing, which improves the stability of ink quality.

[Show abstract][Hide abstract] ABSTRACT: Our objective was to examine the association between the Geriatric Nutritional Risk Index (GNRI) and mortality in Korean hemodialysis (HD) patients. We examined the GNRI of 120 maintenance HD patients and followed these patients for 120 months. Predictors for all-cause death were examined using life table analysis and the Cox proportional hazards model. Life table analysis revealed that subjects with a GNRI < 90 (n = 19) had a marginally lower survival rate than did those with a GNRI ≥ 90 (n = 101) (Wilcoxon test, P = 0.048). Multivariate Cox proportional hazards analyses demonstrated that the GNRI was a significant predictor of mortality (hazard ratio 0.966, 95% confidence interval 0.945-0.995, P = 0.018), after adjusting for age, sex, presence of diabetes mellitus, and body weight. These results demonstrate that the GNRI may be a significant predictor of mortality in Korean HD patients.

[Show abstract][Hide abstract] ABSTRACT: The spontaneous and serial rupture of the bilateral Achilles tendons without history of significant trauma is an uncommon complication in long-term hemodialysis (HD) patients. The majority of these patients have additional predisposing factors, such as previous use of fluoroquinolone antibiotics or corticosteroids. In general, this condition is associated with a coexisting systemic disease, including chronic kidney disease (CKD), secondary hyperparathyroidism, systemic lupus erythematosus (SLE), and diabetes mellitus (DM). Here, we report a 46-year-old man who had been undergoing regular HD for 11 years. He developed a spontaneous and consecutive rupture of both Achilles tendons. Based on previous reports of tendon ruptures in uremic patients and on the patient's lack of corticosteroid or fluoroquinolone use, we believe that secondary hyperparathyroidism was the predisposing factor in this patient. The mechanism seems to be related to a high parathyroid hormone (PTH) level, which results in osteolytic bone resorption at the tendon insertion site. Treatment and prevention of such tendon ruptures include early surgical repair and control of secondary hyperparathyroidism, by use of vitamin D analogs, and total parathyroidectomy, with or without autotransplantation of a parathyroid gland.

[Show abstract][Hide abstract] ABSTRACT: The herpesviridae family includes, among others, herpes simplex virus, varicella zoster virus, Epstein-Barr virus, and cytomegalovirus. Herpesviridae viral infections (HVIs) can lead to serious complications in lymphoma patients undergoing chemotherapy. There is no consensus on the dose and duration of antiviral prophylaxis in these patients. We retrospectively analyzed the incidence and risk factors for HVI in lymphoma patients undergoing chemotherapy.
We reviewed the records of 266 patients who were newly diagnosed with lymphoma and received chemotherapy without acyclovir prophylaxis between June 1996 and August 2009.
The cumulative incidence rate of HVI was 20.16% for 5 years from the start of chemotherapy. Independent predictive factors for HVI in lymphoma patients were: female sex [hazard ratio (HR) 2.394; 95% confidence interval (CI): 1.245-4.607; P=0.009], cumulative dose of steroids per body surface area of at least 2500 mg/m(2) (HR 7.717; 95% CI: 3.814-18.703; P<0.001), and history of neutropenic fever (HR 0.297; 95% CI: 0.150-0.588; P<0.001).
Female sex, high dose of steroids per body surface area, and neutropenic fever were risk factors for HVI in patients with lymphoma undergoing chemotherapy without acyclovir prophylaxis.

[Show abstract][Hide abstract] ABSTRACT: For treating advanced non-small cell lung cancer (NSCLC), epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are known to be very effective in nonsmokers, women, Asian and person with EGFR mutations. The efficacy of EGFR-TKI was analyzed based on the radiologic studies and the serum levels of carcinoembryonic antigen (CEA) to evaluate whether serum CEA can be used as a predicative marker of the response to EGFR-TKI therapy.
[Show abstract][Hide abstract] ABSTRACT: Hepatosplenic T-cell lymphoma is a rare histologic type of peripheral T-cell lymphoma, which is characterized clinically by predominant involvement of the liver and spleen, with little or no adenopathy, and an often aggressive course. We experienced a case of a 44-year-old female who was diagnosed with hepatosplenic γ δ T-cell lymphoma with bone marrow involvement. The patient was treated with multi- agent chemotherapy with Bortezomib plus CHOP (cyclophosphamide, vincristine, prednisone, doxorubicin), Alemtuzumab plus DHAP (dexamethasone, cisplatin, cytarabine), and IMVP-16 (Ifosfamide, MTX, etoposide); however, she failed to achieve partial remission. After salvage chemotherapy (GemOx: Gembicine, oxaliplatin, dexamethasone), she underwent allogeneic stem cell transplantation from an HLA sibling donor with one mismatch . The patient is currently living and has remained in complete remission for 6 months since transplantation.
