The signal intensity of paranasal sinus mucocele is highly variable, ranging from high to low on both T1 weighted and T2 weighted sequence, This variation is likely due to the combined effects of decreased free water concentration, cross-linking and polymerization of the macromolecular mucus glycoprotein, and increased viscosity. We have experienced three cases of the paranasal sinus mucocele with different signal intensity on Magnetic Resonance Imaging. We describe MR characteristics of the paranasal sinus mucocele and compare with MR characteristics for other paranasal sinus disease.

PURPOSE: Prostate cancer is rarely diagnosed in men younger than 40 years of age. At present, the available data show a low rate of cancer detection from prostate-specific antigen (PSA) screening of this group of young men. We analyzed the outcome of prostate biopsy results in patients of this age group with a high PSA. MATERIALS AND METHODS: Between October 1997 and August 2008, a total of 81 men less than 40 years of age were referred from the Health Care Promotion Center as the result of elevated PSA levels. Six men with prostatitis were excluded. The remaining 75 men were asymptomatic and had normal findings on the digital rectal examination (DRE) and were selected to have a transrectal ultrasound-guided prostate biopsy for suspected prostate cancer. The patients with sustained high PSA levels underwent repeat biopsies. RESULTS: The median age of the 75 men was 33 years (range, 26-40 years) and the mean PSA level was 6.57 ng/ml (range, 4.32-13.45 ng/ml). The results of the primary biopsy was 1 (1.3%) case of prostate cancer, 70 cases (93%) with benign tissue, 2 cases (2.6%) with inflammation, and 1 case each (1.3%) with high grade intraepithelial neoplasia (HGPIN) and atypical small acinar proliferation (ASAP). Of the 10 men who underwent a second biopsy, all had benign findings. Three of the men who underwent a third biopsy all had benign tissue findings. CONCLUSIONS: The prostate cancer detection rate in young men less than 40 years of age with high PSA levels and normal DREs was very low. Repeat biopsy for sustained high PSA levels in young men less than 40 years of age may not be indicated.

PURPOSE: To evaluate the efficacy and safety of artificial urinary sphincter (AUS) for the treatment of stress urinary incontinence (UI) after prostate surgery. MATERIALS AND METHODS: We performed a retrospective chart review of 19 patients who underwent AUS implantation from July 2003 to November 2008. Efficacy was evaluated in terms of the postoperative changes in daily pad use, incontinence visual analogue scale (I-VAS), International Continence Society male-Short Form questionnaire (ICS-male SF), Incontinence Quality of Life questionnaire (I-QoL), and patients' satisfaction postoperatively. No pad use was defined as cure, and use of 1 pad or fewer per day as improvement. Cure and improvement were regarded as success. Complications and durability of the AUS were evaluated. RESULTS: The median age of the patients was 70.0 years (range, 47-76 years). With a median follow-up period of 11.8 months (range, 6.2-48.1 months), the success rate was 68.4% (13/19; cure in 12 and improvement in 1). I-VAS, subscale scores of ICS-male SF (incontinence and QoL), and total and subscale scores of I-QoL (psychosocial impact, social embarrassment, avoidance, and limiting behaviors) were significantly improved. Fifteen (78.9%) patients reported being satisfied. Six (31.5%) patients required revision: volume adjustment for 2, second cuff implantation for 2, pump reposition for 1, and pump reposition, volume adjustment, and second cuff implantation for 1. One of the patients who had a second cuff implantation had the sphincter explanted for infection. CONCLUSIONS: Despite the high rate of revision, the satisfaction rate was high and the quality of life was significantly improved after AUS implantation for urinary incontinence after prostate surgery.

Although stress-induced cardiomyopathy (SCMP) is a reversible disease and the prognosis is usually excellent, several complications can occur and can result in fatal adverse events. The formation of left ventricular (LV) thrombus is one of these critical complications of SCMP. This report describes a case of SCMP complicated by formation of a LV thrombus that became increasingly mobile as LV contractility recovered, and for which surgical removal was performed. Here, we report a case of SCMP complicated by LV thrombus and review the literature regarding this topic.

The necessity of routine prostate biopsy prior to transurethral resection of the prostate (TURP) in elderly comorbid patients with a high prostate specific antigen (PSA) level remains controversial. We assessed the role of TURP in prostate cancer diagnosis in these individuals. A total of 197 patients underwent TURP in conjunction with prostatic needle biopsy. Pathologic reviews of specimens of TUR chips and biopsy cores were analyzed. Overall, prostate cancer (CaP) was detected in 114 patients (57.6%). Ninety-eight cancers (86%) were detected with TURP and biopsy, and seven cancers (6.1%) with only TURP. The Gleason score of a TUR-specimen was identical to that of the biopsy-core in 43.9% of cases. Variables associated with diagnostic accuracy in the TUR-specimens included the prebiopsy PSA level, prostate specific antigen density (PSAD), and the Gleason score in biopsy cores. In patients with a PSA level and a PSAD that was greater than 15.4 ng/mL and 0.69 ng/mL/g, respectively, 100% of the cancers were detected in the TUR-specimens. Our results suggest that a prostatic biopsy might be omitted prior to TURP in elderly patients with significant co-morbidity and levels for PSA of >15.4 ng/mL.

OBJECTIVE: To investigate the frequency of gut inflammation in the ankylosing spondylitis and the role of gut lesion in the pathogenesis of the ankylosing spondylitis. METHODS: Ileocolonoscopy and biopsy were performed in 24 patients with. ankylosing spondylitis. RESULTS: 1) Endoscopic lesions were observed in 7 patients(29.2%) of 24 patients and more often in the terminal ileum(6/7) than in the colon(I/7). Among 7 patients with endoscopic lesions, 5 patients were presented as juvenile chronic arthritis. 2) Histologic signs of gut inflammation were detected in 14 patients(58. 3%). Actue lesions were seen in 2 patients (8. 3%) and chronic lesions were seen in 12 patients (50%). 3) In 12 patients without the involvement of peripheral joints, acute lesion was not seen(0%), and chronic lesions were seen in 6 patients(50%). In 12 patients with the involvement of peripheral joints, acute lesions were seen in 2 patients (16.7%), and chronic lesions were seen in 6 patients(50%). Gut inflammations were more frequent in patients with the involvement of peripheral joints than in those without the involvement of peripheral joints. 4) In 12 patients without the administration of sulfasalazine, acute lesion was not seen(0%), and chronic lesions were seen in 7 patients(58.7%) In 12 patients with the administration of sulfasalazine, acute lesions were seen in 2 patients (16.7%), and chronic lesions were seen in 5 patients(41.6%). The frequency of gut lesions in patients without the administration of sulfasalazine was not different from that in patients with the administration. of sulfasalazine (p<0.05). CONCLUSION: Gut inflammation was frequently found in patients with ankylosing spondylitis. Chronic gut inflammation could play a role in the pathogenesis of the ankylosing spondylitis.

BACKGROUND: Hand eczema is one of the most common skin disorders and negatively affects quality of life. However, a large-scale multicenter study investigating the clinical features of patients with hand eczema has not yet been conducted in Korea. OBJECTIVE: To identify the prevalence of various hand diseases, which is defined as all cutaneous disease occurring in hands, and to investigate the clinical features of patients with hand eczema and the awareness about hand eczema in the general population and to compare the prevalence of hand eczema between health care providers and non-health care providers. METHODS: To estimate the prevalence of hand diseases, we analyzed the medical records of patients from 24 medical centers. Patients were assessed by online and offline questionnaires. A 1,000 from general population and 913 hand eczema patients answered the questionnaire, for a total of 1,913 subjects. RESULTS: The most common hand disease was irritant contact dermatitis. In an online survey, the lifetime prevalence of hand eczema was 31.2%. Hand eczema was more likely to occur in females (66.0%) and younger (20~39 years, 53.9%). Health care providers and housewives were the occupations most frequently associated with hand eczema. Winter (33.6%) was the most common season which people experienced aggravation. The 63.0% and 67.0% answered that hand eczema hinders their personal relationship and negatively affects daily living activities, respectively. CONCLUSION: Hand eczema is a very common disease and hinders the quality of life. The appropriate identification of hand eczema is necessary to implement effective and efficient treatment.
