A genetic and clinical study was done on 20 index cases and their families who had lived in Chonnam province, visited Chonnam University Hospital from 1968 through 1983, and were diagnosed as peudoxanthoma elasticum based on clinical and histopathological findings. In Chonnam province, pseudoxanthoma elsticum occurred in a incidence of more thar, one per 125,000. The male to female ratio was 1: 1.25 (8: 10) with only the cases of familial occurrence although the sex ratio was 1: l. 85 (7: 13) among 20 index cases. Among 8 index cases showing familial occurrence, 6 showed autosomal recessive inheritance with 5 Type 1 and 1 Type 2 whereas 2 showed the autosomal dominant inheritance with both of thern Type 2 (Pope), pointing out the genetic heterogeneity in pseudoxanthorna elsticum. The age of patients ranged from 12 to 42 years old at the time of their first visit to our hospital, but the age that the patients first recognized the disease onset ranged from 9 to 22 years old. The duration of t he disease was also variable ranging from 11/2 to 30 years. The angioid streaks were observed in 38g of the cases whose disease duration ranged from 11/2 to 20 years. The sites of skin lesions were the neck, axillae and groin in the order of frequency.

OBJECTIVES: The present study examines the relationship between depressive symptoms and subjective chewing and pronunciation ability in Korean seniors. Our goal is to provide the data required to develop appropriate oral health interventions programs for seniors. METHODS: The Center for Epidemiologic Studies-Depression Scale (CES-D) is widely used depressive symptoms assessment. A Korean version was used for the 2009 Community Health Survey, which was consulted to extract the present study's subjects, comprising 50,694 Korean seniors (males, 20,582; females, 30,112) aged ≥65 years. Those with a CES-D score ≥16 were rated 'depressed.' SAS version 9.3 was used for the data analysis. RESULTS: Prevalence of depressive symptoms increased as the subjects' socioeconomic status decreased, number of health issues increased, health behavior worsened, and chewing and pronunciation discomfort increased. Males with chewing difficulties were found to have 1.45 times (95% confidence interval [CI], 1.29 to 1.63) greater risk of depressive symptoms than those without, while males with pronunciation discomfort were found to have 1.97 times greater risk of depressive symptoms than those without (95% CI, 1.76 to 2.20). Females with chewing difficulty were found to have 1.50 times (95% CI, 1.39 to 1.61) greater risk of depressive symptoms than those without, and females with pronunciation discomfort were found to have 1.55 times greater risk of depressive symptoms than those without (95% CI, 1.44 to 1.67). CONCLUSIONS: Intervention programs designed to help with oral health management and alleviate depressive symptoms in seniors are urgently needed. As the prevalence of depressive symptoms may vary geographically, research examining potential variance at city, district, and town levels would be beneficial.

The incidence of cancer is sharply increasing. Cancer is a leading cause of death as well as a significant burden on society. The incidence of urological cancer has shown a higher than average increase and will become an important concern in the future. Therefore, an overall and accurate understanding of the incidence of urological cancer is essential. In this study, which was based on the Korea National Cancer Incidence Database, annual incident cases, age-standardized incidence rates, annual percentage change (APC), and distribution by age group were examined in kidney, bladder, and prostate cancers, respectively. From 1999 to 2011, the total number of each type of urological cancer was as follows: kidney cancer (32,600 cases, 25.5%), bladder cancer (37,950 cases, 29.7%), and prostate cancer (57,332 cases, 44.8%). The age-standardized incidence rates of prostate cancer showed a significant increase with an APC of 12.3% in males. Kidney cancer gradually increased with an APC of 6.0% for both sexes and became the second most frequent urological cancer after 2008. Bladder cancer showed no significant change with an APC of -0.2% for both sexes and has decreased slightly since 2007. The distribution of kidney cancer according to age showed two peaks in the 50- to 54-year-old and 65- to 69-year-old age groups. Bladder and prostate cancers occurred mostly in the 70- to 74-year-old age group. The proportions of male to female were 2.5:1 in kidney cancer and 5.6:1 in bladder cancer. We have summarized the incidence trends of kidney, bladder, and prostate cancers and have provided useful information for screening and management of these cancers in the future.

Human cytomegalovirus (HCMV) isolated from Korean patients is different in the antigenic and genomic structure of gB from the laboratory-adapted strain. To dissect the reactivity to HCMV glycoprotein B (gB) domains, each domain gene of gB of HCMV SNUCH1, Korean isolate, was amplified from the extracted DNA of the virus-infected fibroblasts with the specific primers by polymerase chain reaction (PCR). Amplified DNA was cloned into pcDNA3. Immunofluorescent staining and western blot analysis revealed that the expressed gB in mammalian cells was immunoreactive and equivalent to the naturally expressed gB in virus-infected fibroblasts. The antigenic component reactive with monoclonal antibodies, MCMVA 57, 88, and 98 appeared at the D3 domain of gB molecule, and that with MCMVA 66 and 135 at the D2b domain. Antibody titer was measured with HCMV-infected fibroblasts and the domains of gB expressed in mammalian cells. There was no correlation between the antibody titer to the whole HCMV and neutralizing antibody titer, and between the antibody titer to whole HCMV and whole gB. It was more reasonable to use whole gB than whole HCMV in the comparison with the neutralizing antibody titer. D3 was representative domain in gB molecule in the anti-gB reactivity. Conclusively it is highly recommendable to use the representing isolates in Korea and its domains for the detection of antibody or the analysis of antigen in the aspect of immunological properties and molecular structures.

PURPOSE: The relationship between pathological parameters, such as blood vessel, lymphatic and perineural invasions, and prognosis, are controversial. We retrospectively analyzed the charts of patients with bladder cancer to identify the prognostic significance of these parameters. MATERIALS AND METHODS: A retrospective review of 125 of 181 patients with bladder cancer treated with radical cystectomy was conducted. Patients treated with neoadjuvant or adjuvant chemotherapy and those who were found to have lymph node metastasis after cystectomy were excluded from the study. RESULTS: The mean patient age was 62.5 years(range 39-84) and the overall median follow-up was 40.1months(range 1 to 146). Blood vessel, lymphatic, and perineural invasions were present in 8.8%, 20.8%, 8.8% of the specimens, respectively, and 28% of the patients had at least one of three factors. Univariate analysis revealed that blood vessel lymphatic, and perineural invasions were prognostic predictors of survival. However, only tumor stage and blood vessel invasion were calculated to be independent factors of survival on multivariate analysis. CONCLUSIONS: In this series, the pathological stage and blood vessel invasion are significant parameters of tumor-free survival in patients who have undergone cystectomy for bladder cancer. Our findings suggest that blood vessel, lymphatic, and perineural invasions should be examined more carefully.

PURPOSE: This study was performed to evaluate the level of I-TAC in tears of patients with dry eye syndrome and its correlation with the tear surface parameters. METHODS: I-TAC levels were measured by enzyme-linked immunosorbent assay (ELISA) in tear samples collected from 33 dry eye patients (16 patients with Sjogren syndrome and 17 patients with non-Sjogren syndrome) and 15 control subjects. The correlations between I-TAC levels and tear surface parameters including tear film break-up time (BUT), basal tear secretion, tear clearance rate (TCR), corneal sensation, keratoepitheliopathy and conjunctival goblet cell density were analyzed. RESULTS: The mean levels of I-TAC were 717+/-377 pg/ml in patients with dry eye and 444+/-119 pg/ml in control subjects (P=0.003). The mean levels in Sjogren syndrome patients (1261+/-324 pg/ml) were significantly higher than those of non-Sjogren syndrome patients (614+/-131 pg/ml, P=0.003). I-TAC levels correlated significantly with basal tear secretion (P=0.006), TCR (P=0.007), keratoepitheliopathy (P=0.022) and goblet cell density (P<0.001), but did not correlate with BUT (P=0.110) and corneal sensation (P=0.090). CONCLUSIONS: The level of I-TAC is elevated in tears of patients with dry eye syndrome including Sjogren syndrome. The level correlates with disease severity and tear surface parameters.
