We recently encountered a case of hereditary spherocytosis coexisting with Gilbert's syndrome. Patient was initially diagnosed with Gilbert's syndrome and observed, but other findings suggestive of concurrent hemolysis, such as splenomegaly and gallstones were noted during the follow-up period. Therefore, further evaluations, including a peripheral blood smear, osmotic fragility test, autohemolysis test, and red blood cell membrane protein test were performed, and coexisting hereditary spherocytosis was diagnosed. Genotyping of the conjugation enzyme uridine diphosphate-glucuronosyltransferase was used to confirm Gilbert's syndrome. Because of the high prevalence rates and similar symptoms of these 2 diseases, hereditary spherocytosis can be masked in patients with Gilbert's syndrome. In review of a case and other article, the possibility of the coexistence of these 2 diseases should be considered, especially in patients with unconjugated hyperbilirubinemia who also have splenomegaly and gallstones.

BACKGROUND AND OBJECTIVES: It is necessary to establish the most efficient diagnostic and therapeutic method for benign paroxysmal positional vertigo (BPPV), which is appropriate for Korean healthcare system. We aimed to evaluate current state of Korean clinician's diagnostic and therapeutic approaches for BPPV. MATERIALS AND METHODS: A 16-item survey was emailed to the members of dizziness department of Otology Research Interest Group in the Korean Otologic Society (n=68). 43 were returned and analyzed. RESULTS: All respondents (100%) used Dix-Hallpike test as a diagnostic tool for vertical canal-BPPV. Supine roll test was used for diagnosing lateral canal BPPV in nearly all the respondents (97.7%). Epley maneuver was chosen as otolith repositioning maneuver (ORM) for posterior canal BPPV in all respondents and barbecue rotation (BBQ) was used for treating lateral canal BPPV with geotropic nystagmus in 95.3% of respondents. Extreme variation was noted for therapeutic approach of lateral canal BPPV with ageotropic nystagmus BBQ, with 4 kinds of ORM and adjunctive measures to liberate otolith from cupula, while BBQ was again the most commonly used ORM (76.7%). CONCLUSION: The development of practical and efficient ORM for lateral canal BPPV with ageotropic nystagmus is necessary.

PURPOSE: There are still debates on the benefit of mass screening for prostate cancer (PCA) by prostate specific antigen (PSA) testing, and on systemized surveillance protocols according to PSA level. Furthermore, there is a paucity of literature on current practice patterns according to PSA level in the Korean urologic field. Here, we report the results of a nationwide, multicenter, retrospective chart-review study. MATERIALS AND METHODS: Overall 2122 Korean men (>40 years old, PSA >2.5 ng/mL) were included in our study (from 122 centers, in 2008). The primary endpoint was to analyze the rate of prostate biopsy according to PSA level. Secondary aims were to analyze the detection rate of PCA, the clinical features of patients, and the status of surveillance for PCA according to PSA level. RESULTS: The rate of prostate biopsy was 7.1%, 26.3%, 54.2%, and 64.3% according to PSA levels of 2.5-3.0, 3.0-4.0, 4.0-10.0, and >10.0 ng/mL, respectively, and the PCA detection rate was 16.0%, 22.2%, 20.2%, and 59.6%, respectively. At a PSA level >4.0 ng/mL, we found a lower incidence of prostate biopsy in local clinics than in general hospitals (21.6% vs. 66.2%, respectively). A significant proportion (16.6%) of patients exhibited high Gleason scores (> or =8) even in the group with low PSA values (2.5-4.0 ng/mL). CONCLUSION: We believe that the results from this nationwide study might provide an important database for the establishment of practical guidelines for the screening and management of PCA in Korean populations.

Malignant colonic obstruction can lead an emergency operation for decompression, and this can cause post-operative complications due to poor bowel preparation. Self-expandable metal stent (SEMS) insertion is useful for avoiding an emergency operation and unnecessary complications. However, SEMS insertion for dual malignant colonic obstructions is very rare. We report here on a case of two SEMS that were inserted in dual malignant colonic obstructions caused by synchronous colon cancer. A 66-year-old man visited our hospital due to abdominal distension. Sigmoidoscopy and an abdominopelvic computerized tomographic (CT) scan revealed synchronous colon cancer at the splenic flexure and distal descending colon with dual obstruction. The initial SEMS insertion on the descending colon was not effective for decompression due to the proximal obstruction. After the second SEMS insertion on the splenic flexure through the first stent, all the signs and symptoms due to obstruction disappeared. SEMS insertion is considered to be useful for treating dual malignant colonic obstruction caused synchronous colon cancer.

PURPOSE: The aim of this study is to report on preliminary data regarding the prevalence of major eye diseases in Korea. METHODS: We obtained data from the Korea National Health and Nutrition Examination Survey, a nation-wide cross-sectional survey and examinations of the non-institutionalized civilian population in South Korea (n = 14,606), conducted from July 2008 to December 2009. Field survey teams included an ophthalmologist, nurses, and interviewers, traveled with a mobile examination unit and performed interviews and ophthalmologic examinations. RESULTS: The prevalence of visual impairment, myopia, hyperopia and astigmatism in participants over 5 years of age was 0.4 +/- 0.1%, 53.7 +/- 0.6%, 10.7 +/- 0.4%, and 58.0 +/- 0.6%, respectively. The prevalence of strabismus and blepharoptosis in participants over 3 years of age was 1.5 +/- 0.1% and 11.0 +/- 0.8%, respectively. In participants over 40 years of age, the prevalence of cataract, pterygium, early and late age-related macular degeneration, diabetic retinopathy and glaucoma was 40.2 +/- 1.3%, 8.9 +/- 0.5%, 5.1 +/- 0.3%, 0.5 +/- 0.1%, 13.4 +/- 1.5%, and 2.1 +/- 0.2%, respectively. CONCLUSIONS: This is the first nation-wide epidemiologic study conducted in South Korea for assessment of the prevalence of eye diseases by both the Korean Ophthalmologic Society and the Korea Center for Disease Control and Prevention. This study will provide preliminary information for use in further investigation, prevention, and management of eye diseases in Korea.

OBJECTIVE: Although increased expression of receptor for advanced glycation end products (AGE) in osteoarthritis (OA) has been reported, little is known concerning the role of AGEs in the pathogenesis of OA. This study was undertaken to determine the effect of AGEs on the regulation of matrix metalloproteinase (MMP) expressions and activities in human OA chondrocytes METHODS: OA chondrocytes were treated with increasing doses of AGE-bovine serum albumin (AGE-BSA). The expressions of MMPs were determined by both enzyme-linked immunosorbent assay (ELISA) and immunoblot analysis. The activities of MMPs were evaluated by both gelatin and casein zymography assays. In addition, electrophoretic mobility shift assay (EMSA) was employed to investigate the DNA binding activity of nuclear factor-kappa B (NF-kappaB) by AGE-BSA treatment. RESULTS: The productions of MMP-1, -3, and -13 were significantly elevated by AGE-BSA in a dose dependent manner. The elevated activities of MMP-1, -3, and -13, and TNF-alpha by AGE-BSA were also observed. DNA binding activity of NF-kappaB was markedly increased by AGE-BSA treatment implicating possible involvement of NF-kappaB mediated pathway in the AGE-BSA induced MMP-1, -3, and -13, and TNF-alpha productions in OA chondrocytes. Taken together, this study demonstrates the stimulatory effect of AGE-BSA on the productions of MMPs and TNF-alpha and suggests the possible involvement of NF-kappaB mediated pathway in OA chondrocytes. CONCLUSION: These results suggest that AGE may play a role in pathogenesis of OA.

Prosthetic vascular graft infection (PVGI) is a relatively uncommon complication of peripheral vascular surgery and although rare, is the most severe complication in reconstructive vascular surgery. The early diagnosis of this complication can reduce the mortality. We report a case of aorto-femoral bypass graft infection, which was diagnosed by Tc-99m HMPAO WBC scan, complicated with infective endocarditis. A 60-year-old man had been operated with aortofemoral bypass graft because of aortojejunal fistula due to abdominal aortic aneurysm. Nine months later, he was admitted with fever of two months' duration. On echocardiolography, aortic regurgitation and vegetation were observed, and then he was diagosed with infective endocarditis. He was treated with antibiotics for 6 weeks. Recurrent bacteremia of unknown origin persisted despite antibiotic therapy. Multiple microorganisms were separately isolated from the blood cultures. He complained of intermittent right groin pain. Imaging study (CT, MRI, US) showed no definite evidence of graft infection. However, Tc-99m HMPAO WBC scan demonstrated uptake in the aortofemoral bypass graft site. The patient underwent emergent aortofemoral graft removal with axillobifemoral bypass and right femoropopliteal bypass.

Secondary amyloidosis is characterized by accumulation of an amorphous proteinous material in the various tissue and organs with infectious disease or inflammatory disease. Symptoms of the amyloidosis are variable according to the involved organs. Reactive amyloidosis of bladder in rheumatoid arthritis (RA) is a rare condition with hematuria in the most cases. However, we report two cases of patients with RA, who have frequency due to secondary amyloidosis of bladder without hematuria. Therefore secondary amyloidosis of urinary bladder should be considered as a possible cause of frequency in patients with long-term RA.

Cytomegalovirus (CMV) infection is more frequent in immunocompromised patients those with acquired immunodeficiency syndrome (AIDS), malignant disease, steroid therapy. However, CMV can infect a healthy person who has normal immunity. Most cases of CMV infections are due to reactivation of latent virus. We report a case of cytomegalovirus colitis in a 73 years old woman who has congestive heart failure with normal immunity. Sigmidoscopy reveals cobble stone like mucosa and deep ulceration. CMV infection produces a cytomegalic cell containing a intranuclear inclusion, which is surrounded by clear halo in Hematoxylin-Eosin stain. Immunohistochemical stain for CMV reveals focal positive in cytoplasm and in nuclei of large cells. We diagnosed CMV colitis with histopathologic finding and immunohistochemistry through sigmoidoscopic mucosal biopsy.
