OBJECTIVE: Several lines of evidence suggest that brain-derived neurotrophic factor (BDNF) plays a role in the pathophysiology of anxiety. We analyzed the association of the BDNF gene polymorphism, G196A (val66met), in the coding region of exon XIIIA in chromosome 11p13, and generalized social anxiety disorder (GSAD). METHODS: Patients with GSAD (n=73) and age-matched control subjects (n=152) were tested for the BDNF (val66met) polymorphism. A clinical interview and a Mini-International Neuropsychiatric Interview were conducted by trained psychiatrists in order to diagnose GSAD. The symptomatic characteristics of the GSAD patients were assessed with the Hamilton Anxiety Rating Scale, the Beck Anxiety Inventory, the Retrospective Self Report of Inhibition, the Spielberger State-Trait Anxiety Inventory, and the Liebowitz Social Anxiety Scale. RESULTS: There were no significant differences in the frequencies of the genotypes (chi2=0.961, degree of freedom [df]=2, p=0.619), alleles (chi2=0.415, df=1, p=0.519), or allele (methionine) carriers (chi2=0.019, df=1, p=0.889) between the patients and controls. In addition, when we compared the severity of social anxiety symptom as determined by the clinical scales with the genotypes of the BDNF gene, we could not find any significant differences between the genotypes or allele carriers. CONCLUSION: These results do not support the hypothesis that the BDNF gene might be a candidate gene for susceptibility or severity of GSAD in the Korean population in this study.

Carbon monoxide (CO) is a well-known chemical asphyxiant, which causes tissue hypoxia with prominent neurological and cardiovascular injury. After exposure to CO, several cardiac manifestations have been reported, including arrhythmias, acute myocardial infarction, and pulmonary edema. However, an ST elevation myocardial infarction (STEMI) due to CO poisoning is a very rare presentation, and the treatment for STEMI due to CO poisoning is not well established. Here, we report a rare case of STEMI complicated by increased thrombogenicity secondary to acute CO poisoning and complete revascularization after antithrombotic treatment.

BACKGROUND: Atopic dermatitis (AD) is characterized by pruritic and eczematous skin lesions, which often cause depressive symptoms, anxiety, stress, sleep disturbances, social withdrawal, and stigmatization. METHODS: In total, 23,442 subjects (434 AD patients and 23,008 control subjects) aged 19 years or older and without a history of major medical illness or depressive disorders were selected from The Fifth Korea National Health and Nutrition Examination Survey 2007-2012. Following the initial selection, 2,170 age- and sex-matched control subjects were selected using 1:5 propensity score matching. Multiple logistic regression analysis was performed to identify the presence of depressive symptoms of at least 2 weeks in duration. RESULTS: The demographic, socioeconomic, and clinical characteristics of AD patients and control subjects were presented and compared, and some variables differed significantly between groups. Presence of depressive symptoms was set as dependent variable, and multiple logistic regression analysis was performed as follows: (1) unadjusted; (2) with alcohol use, exercise status, smoking status, and body mass index (BMI) adjusted for; and (3) with alcohol use, exercise status, smoking status, marital status, occupation, BMI, total caloric intake, history of hypertension, and history of diabetes mellitus adjusted for. Depressive symptoms were significantly higher (odds ratios, 1.46, 1.40, and 1.36; 95% confidence intervals, 1.09-1.95, 1.0.4-1.88, and 1.01-1.85, respectively) in AD patients relative to those of matched controls. CONCLUSION: AD and clinical depression interact closely, and causal relationships between the two conditions have frequently been observed. Physicians should consider mental health interventions cautiously. It is particularly important that primary care physicians provide comprehensive, continuous long-term care.

PURPOSE: AQP-1 (Aquaporin-1) and VEGF (vascular endothelial growth factor) are known to play an important role in ultrafiltration in peritoneal dialysis. The aim of this study was to evaluate the expression of AQP-1 and VEGF and VEGFR-1 (VEGF type 1 receptor) in peritoneums obtained from uremic non-dialyzed patients and peritoneal dialysis patients and to see if expression of these molecules are correlated with each other and with pathological findings in peritoneum. METHODS: Peritoneal expressions of AQP-1, VEGF and VEGFR-1 were examined by immunohistochemistry using specific antibody to each molecule. The degree of vascular proliferation and inflammation in peritoneal tissues were assessed semi-quantitatively by a single pathologist. RESULTS: AQP-1, VEGF and VEGFR-1 were mainly expressed in the vascular endothelial cells in the peritoneum. No significant difference in peritoneal expression of these molecules was found according to the clinical situations in which peritoneal tissues were obtained. The degree of expression of AQP-1 and VEGF were related to each other but not related to expression of VEGFR-1. The expressions of AQP-1 and VEGF were related to the vascular proliferation. The expression of AQP-1 was also related to inflammation. CONCLUSION: In end-stage renal disease patients before and after initiation of peritoneal dialysis, the peritoneal expressions of AQP-1 and VEGF were related to vascular proliferation. Inflammation might have some influence in expression of AQP-1.

OBJECTIVES: Many patients diagnosed with cancer suffer from various psychiatric symptoms such as depression, anxiety and insomnia as well as cancer itself. Patients with cancer are more vulnerable to possible adverse events of psychotropic medications. Although antidepressants are widely used among cancer patients, there is little information about tolerability of antidepressants. This study was conducted to compare tolerability of antidepressants in cancer patients referred for psychiatric consultation. METHODS: The participants were cancer patients who had been referred to psychiatrist for their psychiatric symptoms. We retrospectively analyzed the data of patients diagnosed with cancer from 9 general hospitals in Korea. The discontinuation rate for a 6 months period after treatment initiation for three antidepressants(Escitalopram, Mirtazapine, Paroxetine) were compared. RESULTS: Antidepressants were prescribed for 96.3% of subjects and Escitalopram 150(47.2%), Mirtazapine 92 (28.9%) and Paroxetine 76(23.9%) were prescribed frequently in order There were no significant differences in discontinuation rates among the three antidepressants during the 6 month period after initiation of pharmacotherapy. But there was a difference in discontinuation rates between inpatients versus outpatients(p<0.0001). CONCLUSIONS: In a naturalistic setting for the antidepressant treatment for cancer patients, it seems that there are no differences in discontinuation rates among these three antidepressants. It is therefore essential that such interactions are carefully considered when treating patients of antidepressants who already have cancer.

BACKGROUND: The prevalence of acute kidney injury (AKI) in elderly patients has grown considerably. Age-associated changes in the immune system can be one of the critical factors determining AKI outcomes. This study aimed to investigate the role of senescence of bone marrow (BM)-derived cells in the development of AKI, focusing on the immune response. METHODS: Female 7-week-old C57BL/6 mice were irradiated and treated with BM cells from either 48-week-old or 8-week-old male mice. Ischemia-reperfusion injury (IRI) was induced, and their functional deterioration, histological tubular damage, and inflammatory responses were compared. For the in-vitro study, lipopolysaccharide (LPS)-stimulated cytokine production by BM cells from old and young mice were examined. RESULTS: At 24 hours after IRI, there was no significant difference in the number of circulating immune cells between the mice transplanted with old or young BM cells. However, the mice with old BM cells showed less functional deterioration and histological tubular injury than those with young BM cells. Moreover, macrophage infiltration and renal cytokine interleukin (IL)-12 levels were lower in the mice with old BM cells at 24 hours post-IRI. Consistently, the in vitro study showed that LPS-induced production of cytokines interferon-γ, monocyte chemoattractant protein-1, and IL-10 was attenuated in cultured old BM cells, suggesting that age-related functional changes in these cells may lead to reduced inflammation in IRI. CONCLUSION: Immunosenescence could affect the susceptibility and response to renal IRI. Further studies specifically addressing age-related alterations can help in the development of treatment strategies for elderly patients with AKI.

BACKGROUND: To meet the need for a subspecialized skin type system, the Baumann skin type (BST) system was proposed. OBJECTIVE: To evaluate the distribution of BST types and influencing factors among Korean women. METHODS: BST questionnaires were administered to 1,000 Korean women. The possible responses were as follows: oily (O) or dry (D), sensitive (S) or resistant (R), pigmented (P) or non-pigmented (N), and wrinkled (W) or tight (T). The correlations of the BST with the subjects' age, location, ultraviolet (UV) ray exposure, drinking and smoking habits, and blood type were assessed. RESULTS: The OSNT, DSNT, DRNT, and OSNW skin types were the most common skin types (55.3%). The O, S, P, and W types accounted for 46.6%, 68.8%, 23.2%, and 31.9%, respectively. The proportion of the O and S type was the highest in Gyeongsangbuk-do (55.0%) and Seoul (77.2%). The proportion of the P and W type was the highest in Gyeongsangbuk-do (33.0%) and Chungcheong-do (39.0%). The O type decreased in the higher age group, whereas the P and W type showed a reversed tendency. In smokers, the proportion of W type was significantly higher than in the non-smokers (66.3% vs. 24.1%, p<0.05). CONCLUSION: The 4 most common BST types were OSNT, DSNT, DRNT, and OSNW. In the comparison across the 4 BST parameters according to the age, region, smoking and drinking habits, occupation, blood type, and UV exposure, significant differences were observed. Individualized and customized skin care is required according to the personal skin type.

OBJECTIVES: Antidepressants are frequently used for treatment of psychological distress among cancer patients. The aim of this study is to investigate the characteristics of psychiatric consultations and antidepressant use for cancer patients. METHODS: Participants in the study included cancer patients who had been referred for psychiatric consultation. A total of 488 patients were recruited from nine general hospitals in Korea. Questionnaires based on medical records, including antidepressants prescribed, were investigated by psychiatrists. RESULTS: The most common psychiatric diagnosis of subjects was depressive disorders (72.4%), followed by anxiety disorders (13.0%), and adjustment disorders (7.3%). Antidepressants were prescribed for 96.3% of subjects and escitalopram, mirtazapine, and paroxetine were prescribed frequently, in order. Anxiolytics and hypnotics were used for 58.2% of the subjects, for which lorazepam and alprozolam were preferred. During the study period, 226 (46.8%) subjects discontinued treatment and the most common cause was improvement of symptoms (123, 54.4%). CONCLUSION: Our results showed a tendency of prescription of antidepressants and anxiolytics and common psychiatric problems in Korean cancer patients. We suppose that these data would be helpful to clinicians who manage psychiatric symptoms of cancer patients.

B cells play an important role in the pathogenesis of rheumatoid arthritis (RA). High levels of B cell activating factor (BAFF) are detected in autoimmune diseases. BAFF and BAFF receptor (BAFF-R) are expressed in B and T cells of RA synovium. The study was undertaken to identify the NF-kappaB signal pathway involved in the induction of BAFF-R in human B cells. Immunohistochemical staining of NF-kappaB p65, NF-kappaB p50, BAFF, and BAFF-R was performed on sections of synovium from severe and mild RA and osteoarthritis (OA) patients. Peripheral blood mononuclear cells (PBMCs) were isolated from control and RA patients and B cells were isolated from controls. BAFF-R was analyzed by flow cytometry, realtime PCR and confocal staining after treatment with NF-kappaB inhibitors. NF-kappaB p65, NF-kappaB p50, BAFF, and BAFF-R were highly expressed in severe RA synovium relative to mild RA synovium or OA synovium. BAFF-R expression was reduced by NF-kappaB inhibitors in PBMCs and B cells from normal controls. We also showed reduction in expression of BAFF-R via inhibition of the NF-kappaB pathway in PBMCs of RA patients. BAFF/BAFF-R signaling is an important mechanism of pathogenesis in RA and that BAFF-R reduction by NF-kappaB blocking therapy is another choice for controlling B cells in autoimmune diseases such as RA.
