    Background For more effective and safer usage of antibiotics, the dosing strategy should be individualized based on the patients’ characteristics, including race. The aim of this study was to investigate the population pharmacokinetic (PK) profiles of piperacillin and tazobactam in Korean patients with acute infections. Materials and Methods At least four consecutive 2/0.25 g or 4/0.5 g doses of piperacillin/tazobactam (TZP) were intravenously infused over 1 h every 8 h for patients with creatinine clearance (CLcr) ≤50 ml/min or CLcr >50 mL/min, respectively. Blood samples from 33 patients at a steady-state were taken pre-dose and at 0 min, 30 min, and 4-6 h after the fourth infusion. The population PK analysis was conducted using a non-linear mixed-effects method. A likelihood ratio test was used to select significant covariates, with significance levels of P <0.05 for selection and P <0.01 for elimination. Results Both piperacillin PK and tazobactam PK were well described by a two-compartment model with first-order elimination. Creatinine clearance and body weight, as covariates on clearance (CL) and volume of central compartment (V1), were selected among the covariates possibly affecting PK parameters of both drugs. CL was defined as CL = 2.9 + 4.03 × CLcr /47 for piperacillin and CL = 1.76 + 4.81 × CLcr /47 for tazobactam. V1 was defined as V1 = 19.5 × weight/60 for piperacillin and V1 = 22.6 × weight/60 for tazobactam. Conclusion The PK profiles of TZP at a steady-state in Korean patients with acute infections were well described by a two-compartment model with first-order elimination. Both piperacillin and tazobactam clearances were significantly influenced by creatinine clearance. PMID:27659435

    Cytokines/chemokines play key roles in modulating disease progression in human immunodeficiency virus (HIV) infection. Although it is known that early HIV-1 infection is associated with increased production of proinflammatory cytokines, the relationship between cytokine levels and HIV-1 pathogenesis is not clear. The concentrations of 18 cytokines/chemokines in 30 HIV-1 negative and 208 HIV-1 positive plasma samples from Korean patients were measured by the Luminex system. Early HIV-1 infection was classified according to the Fiebig stage (FS) based on the characteristics of the patients infected with HIV-1. Concentrations of interleukin-12 (IL-12), interferon-inducible protein-10 (IP-10), macrophage inflammatory protein-1α (MIP-1α) and regulated upon activation, normal T cells expressed and secreted (RANTES) were increased significantly during the early stage of HIV-1 infection (FS II-IV) compared with the HIV-1-negative group. Of these cytokines, an elevated level of IP-10 was the only factor to be correlated positively with a higher viral load during the early stages of HIV-1 infection (FS II-IV) in Koreans (R = 0.52, P < 0.0005). Therefore, these results suggest that IP-10 may be an indicator for HIV-1 viremia and associated closely with viral replication in patients with early HIV-1 infection.

    The endosymbionts of 4 strains of Acanthamoeba (KA/E9, KA/E21, KA/E22, and KA/E23) isolated from the infected corneas of Korean patients were characterized via orcein stain, transmission electron microscopic examination, and 16S rDNA sequence analysis. Double membrane-bound, rod-shaped endosymbionts were distributed randomly throughout both the trophozoites and cysts of each of Acanthamoeba isolates. The endosymbionts of KA/E9, KA/E22, and KA/E23 were surrounded by electron-translucent areas. No lacunae-like structures were observed in the endosymbionts of KA/E21, the bacterial cell walls of which were studded with host ribosomes. Comparative analyses of the 16S rDNA sequences showed that the endosymbionts of KA/E9, KA/E22 and KA/E23 were closely related to Caedibacter caryophilus, whereas the KA/E21 endosymbiont was assigned to the Cytophaga-Flavobacterium-Bacteroides (CFB) phylum. In the 4 strains of Acanthamoeba, the hosts of the endosymbionts were identified as belonging to the Acanthamoeba castellanii complex, which corresponds to the T4 genotype. Acanthamoeba KA/E21 evidenced characteristics almost identical to those of KA/E6, with the exception of the existence of endosymbionts. The discovery of these endosymbionts from Acanthamoeba may prove essential to future studies focusing on interactions between the endosymbionts and the amoebic hosts. PMID:17374972

    We have previously showed that long-term intake of Korean red ginseng (KRG) delayed disease progression in human immunodeficiency virus type 1 (HIV-1)-infected patients. In the present study, to investigate whether this slow progression was affected by KRG intake alone or in combination with HLA factor, we analyzed clinical data in 68 HIV-1-infected patients who lived for more than 5 years without antiretroviral therapy. The average KRG intake over 111.9 ± 31.3 months was 4,082 ± 3,928 g, and annual decrease in CD4 T cells was 35.0 ± 28.7/μl. Data analysis showed that there are significant inverse correlations between the HLA prognostic score (0.29 ± 1.19) and annual decrease in CD4 T cells (r = −0.347; P < 0.01) as well as between the amount of KRG intake and annual decrease in CD4 T cells (r = −0.379; P < 0.01). In addition, KRG intake significantly slowed the decrease in CD4 T cells even when influence of HLA class I was statistically eliminated (repeated-measure analysis of variance; P < 0.05). We also observed significant correlation between KRG intake and a decrease in serum-soluble CD8 antigen level (r = 0.62; P < 0.001). In conclusion, these data show that KRG intake independently and significantly affected the slow depletion of CD4 T cells irrespective of HLA class I. PMID:15817756

    We compared the activities of tedizolid to those of linezolid and other commonly used antimicrobial agents against gram-positive cocci recovered from patients with skin and skin structure infections (SSSIs) and hospital-acquired pneumonia (HAP) in Korean hospitals. Gram-positive isolates were collected from 356 patients with SSSIs and 144 patients with HAP at eight hospitals in Korea from 2011 to 2014. SSSIs included impetigo, cellulitis, erysipelas, furuncles, abscesses, and infected burns. Antimicrobial susceptibility was tested by using the CLSI agar dilution method. All of the gram-positive isolates were inhibited by ≤1 μg/mL tedizolid. The minimum inhibitory concentration [MIC]₉₀ of tedizolid was 0.5 μg/mL for methicillin-resistant Staphylococcus aureus, which was 4-fold lower than that of linezolid. Tedizolid may become a useful option for the treatment of SSSIs and HAP caused by gram-positive bacteria. PMID:26206690

    The role of infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) in terms of survival among dialysis patients remains incompletely understood. In the present multicenter prospective cohort study, we investigated the prevalences of HBV and HCV infection among 3,321 patients receiving maintenance dialysis in Korea, and assessed the impacts of these infections on survival. All included patients underwent hepatitis B antigen (HBsAg) and HCV antibody (Ab) testing, which revealed that 236 patients (7.1%) were HBsAg-positive, and 123 patients (3.7%) were HCV Ab-positive. HBsAg-positive and HCV Ab-positive patients were matched to hepatitis virus-negative patients using a propensity score at a ratio of 1:2. The prevalences of HBV and HCV infection did not significantly differ according to dialysis modality. Linear-by-linear association analysis revealed that hepatitis B prevalence significantly increased with increasing dialysis vintage (p = 0.001), and hepatitis C prevalence tended to be higher with increasing dialysis vintage (p = 0.074). We compared the survival of HBsAg-positive and HCV Ab-positive patients to that of hepatitis virus-negative patients. After propensity score matching, cumulative survival did not differ between HBsAg-positive and HBsAg-negative patients (p = 0.37), while HCV Ab-positive patients showed significantly lower survival than HCV Ab-negative patients (p = 0.03). The main conclusions of the present study are that HBV infection prevalence increased with longer dialysis vintage, and that both HBV and HCV infections were most prevalent among patients with the longest dialysis vintage. Additionally, HCV infection among maintenance dialysis patients is associated with an increased risk of mortality. PMID:26263373

    Background HIV-associated neurocognitive disorder (HAND) is an independent predictor of early mortality and is associated with many difficulties in activities of daily living. We sought to determine the prevalence of and risk factors for HAND in HIV-infected Koreans. In addition, we investigated the performance of screening tools and components of neuropsychological (NP) tests for diagnosing HAND. Methods HIV-infected patients were enrolled consecutively from two different urban teaching hospitals in Seoul, South Korea between March 2012 and September 2012. Participants completed a detailed NP assessment of six cognitive domains commonly affected by HIV. The Frascati criteria were used for diagnosing HAND. Four key questions, international HIV dementia scale (IHDS) and MoCA-K were also assessed as potential tools for screening for HAND. Results Among the 194 participants, the prevalence of HAND was 26.3%. Asymptomatic neurocognitive impairment, minor neurocognitive disorder accounted for 52.9% and 47.1% of the patients with HAND, respectively. In multivariate analysis, hemoglobin levels ≤13g/dL (p=0.046) and the current use of protease inhibitor-based regimen (p=0.031) were independent risk factors for HAND. The sensitivity and specificity of IHDS were 72.6% and 60.8%, and MoCA-K were 52.9% and 73.4%, respectively. IHDS (p<0.001) and MoCA-K (p<0.001) were both useful for screening for HAND. Among NP tests, the sensitivity and specificity of the Grooved Pegboard Test were 90.2% and 72.0%, and the Wisconsin Card Sorting Test were 61.2% and 84.4%, respectively. Conclusions HAND is a prevalent comorbidity in HIV-infected Koreans. Active screening and diagnosis with useful tools, like IHDS, MoCA-K and Grooved Pegboard Test, could be used to identify this important complication. PMID:24580888

    Acne is a chronic inflammatory disease of the pilocebaceous unit that presents with various spectrum and severity. Genetic backgrounds and environmental factors are also considered to be relevant, but few studies have focused on Korean patients. A cross-sectional epidemiologic study on family history of Korean acne patients was performed to analyze family history of acne, and to compare the severity and characteristics of acne in association with family history. A total of 221 patients were enrolled, 98 male (44.3%) and 123 female (55.7%). Patients were grouped as patients with (A+) or without (A-) family history of acne. In a second analysis, patients with any experience of acne treatment were evaluated. Severity of acne was measured with Burton's grading system and Korean Acne Grading System (KAGS). Female patients had a higher tendency to have family history than males (P = 0.002). Group A+ had statistically significant earlier onset of acne (P = 0.002). In inexperienced patients, patients with family history showed a relatively earlier onset (P = 0.084). This study confirmed the role of heredity in acne. Family history of acne is associated with earlier onset of the disease, and more non-inflammatory lesions.

    Background Korean Americans have one of the lowest screening rates for colorectal cancer. Although physician recommendation is one of the most important predictors of cancer screening across populations, only few Korean American patients receive such a recommendation. Methods We interviewed 14 Korean American physicians in Los Angeles area who primarily serve Korean Americans to explore why they are reluctant to recommend colorectal cancer screening to their Korean patients. Results Physicians identified barriers attributable to themselves (i.e., lack of knowledge, fear of medicolegal liability), their patients (i.e., patient’s unfamiliarity with the concept of screening), and the health care system (i.e., lack of referral network, poor reimbursement). Discussion Our results suggest the need for multi-faceted interventions directed at the physicians, their patients, and the health care system. Further research is needed to validate our results and to assess the extent to which they apply to physicians from other racial/ethnic groups. PMID:18607728

    Purpose Roflumilast is the only oral phosphodiesterase 4 inhibitor approved to treat chronic obstructive pulmonary disease (COPD) patients [post-bronchodilator forced expiratory volume in 1 second (FEV1) <50% predicted] with chronic bronchitis and a history of frequent exacerbations. This study evaluated the efficacy and safety of roflumilast in Korean patients with COPD and compared the efficacy based on the severity of airflow limitation. Materials and Methods A post-hoc subgroup analysis was performed in Korean COPD patients participating in JADE, a 12-week, double-blinded, placebo-controlled, parallel-group, phase III trial in Asia. The primary efficacy endpoint was the mean [least-squares mean adjusted for covariates (LSMean)] change in post-bronchodilator FEV1 from baseline to each post-randomization visit. Safety endpoints included adverse events (AEs) and changes in laboratory values, vital signs, and electrocardiograms. Results A total of 260 Korean COPD patients were recruited, of which 207 were randomized to roflumilast (n=102) or placebo (n=105) treatment. After 12 weeks, LSMean post-bronchodilator FEV1 increased by 43 mL for patients receiving roflumilast and decreased by 60 mL for those taking placebo. Adverse events were more common in the roflumilast group than in the placebo group; however, the types and frequency of AEs were comparable to those reported in previous studies. Conclusion Roflumilast significantly improved lung function with a tolerable safety profile in Korean COPD patients irrespective of the severity of airflow limitation. PMID:27189287

    In the early 1990s, 20 haemophiliacs (HPs) were infected with a common source of HIV-1 viruses through the contaminated clotting factor IX. The aim of this study is to review 20 HPs infected with a common source of virus. The enrolled patients have been consecutively treated with Korean red ginseng (KRG), zidovudine (ZDV) or two-drug therapy and highly active antiretroviral therapy (HAART). We determined full-length pol gene over 20 years and human leukocyte antigen (HLA) class I with peripheral blood mononuclear cells and reviewed medical records. Eighteen HPs experienced various opportunistic infections or clinical manifestations. There were significant inverse correlations between the HLA prognostic score and the annual decrease in CD4+ T-cell counts prior to HAART (AD) (P < 0.05) and the amount of KRG and the AD (P < 0.01). From 1998, the HPs had been treated with HAART. Each of the two patients died without and with HAART regimen respectively. At present, 16 HPs have been alive with HAART. Among the 16 HPs, 12 and 4 are on HAART-plus-KRG and HAART only respectively. Eleven HPs including 2 HPs with G-to-A hypermutations had revealed resistance mutations. Ten and two HPs have shown poor adherence and incomplete viral suppres-sion on HAART respectively. Virological failure based on WHO guidelines was not observed on KRG-plus-HAART. Two HPs revealed additional resistance mutations against two classes on KRG-plus-HAART. As a nationwide study, we first report overall features on clinical course of Korean haemophiliacs. Further education on the importance of drug adherence is needed.

    Autochthonous hepatitis E virus (HEV) is an emerging pathogen in developed countries, and several cases of acute HEV infection have been reported in South Korea. However, there have been no reports on HEV-associated Guillain-Barré syndrome (GBS) in Korea. We recently experienced the case of a 58-year-old Korean male with acute HEV infection after ingesting raw deer meat. Persistent cholestasis was resolved by the administration of prednisolone. At 2.5 months after the clinical presentation of HEV infection, the patient developed weakness of the lower limbs, and was diagnosed with GBS associated with acute hepatitis E. To our knowledge, this is the second report on supportive steroid therapy for persistent cholestasis due to hepatitis E, and the first report of GBS in a Korean patient with acute HEV infection.

    Functional Assessment Staging (FAST) was devised to meet the need for a more brief patient-derived rating scale for evaluating changes in functional performance and activities of daily living skills in all the stages of Alzheimer's disease (AD). FAST was administered to 464 patients with probable AD according to the National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria. The patients were also evaluated using the Korean version of the Mini-Mental Status Examination (K-MMSE), the Clinical Dementia Rating (CDR), the Clinical Dementia Rating-Sum of Boxes (CDR-SB), the Global Deterioration Scale (GDS), the Barthel Activities of Daily Living (B-ADL), and the Seoul-Instrumental Activities of Daily Living (S-IADL). For patients with moderate to severe dementia, the Korean versions of the Severe Impairment Battery (SIB-Ko) and Baylor profound mental status examination (BPMSE-Ko) were also administered. There were significant correlations between the FAST and the K-MMSE scores (r= - 0.71, p< 0.001), between the FAST and the SIB-Ko scores (r= - 0.54, p< 0.001) and between the FAST and the BPMSE-Ko scores (r=- 0.46, p< 0.001). The FAST was also correlated with the CDR, the CDR-SB, the B-ADL, and the S-IADL (p< 0.001). Ultimately, FAST is a reliable and valid assessment technique for evaluating functional deterioration in AD patients throughout the disease course. Moreover, the findings of the present study suggest that the FAST elucidates a characteristic pattern of progressive, ordinal, and functional decline in AD in Korean AD patients with dementia.

    Objective The survival of Huntington’s disease (HD) patients is reported to be 15–20 years. However, most studies on the survival of HD have been conducted in patients without genetic confirmation with the possible inclusion of non-HD patients, and all studies have been conducted in Western countries. The survival of patients with HD in East Asia, where its prevalence is 10–50-fold lower compared with Western populations, has not yet been reported. Methods Forty-seven genetically confirmed Korean HD patients from independent families were included in this retrospective medical record review study. Results The mean age at onset among the 47 patients was 46.1 ± 14.0 years. At the time of data collection, 25 patients had died, and these patients had a mean age at death of 57.8 ± 13.7 years. The Kaplan-Meier estimate of the median survival from onset in the 47 patients was 14.5 years (95% confidence interval: 12.3–16.6). None of the following factors were associated with the survival time in the univariate Cox regression analysis: gender, age at onset, normal CAG repeat size, mutant CAG repeat size, and the absence or presence of non-motor symptoms at onset. Conclusion This is the first Asian study on survival in HD patients. Survival in Korean HD patients may be shorter than that reported for Western populations, or at least is in the lower range of expected survival. A larger longitudinal observation study is needed to confirm the results found in this study. PMID:27667189

    Objectives Recently, somatic mutations in KCNJ5, ATP1A1, ATP2B3, and CACNA1D genes were found to be associated with the pathogenesis of aldosterone-producing adenoma (APA). This study aimed to investigate the prevalence of somatic mutations in KCNJ5, ATP1A1, ATP2B3, and CACNA1D and examine the correlations between these mutations and the clinical and biochemical characteristics in Korean patients with APA. Methods We performed targeted gene sequencing in 66 patients with APA to detect somatic mutations in these genes. Results Somatic KCNJ5 mutations were found in 47 (71.2%) of the 66 patients with APA (31 cases of p.G151R and 16 cases of p.L168R); these two mutations were mutually exclusive. Somatic mutations in the ATP1A1, ATP2B3, and CACNA1D genes were not observed. Somatic KCNJ5 mutations were more prevalent in female patients (66% versus 36.8%, respectively; P = 0.030). Moreover, patients with KCNJ5 mutations comprised a significantly higher proportion of patients younger than 35 years of age (19.1% versus 0%, respectively; P = 0.040). There were no significant differences in pre-operative blood pressure, plasma aldosterone, serum potassium, lateralization index, and adenoma size according to mutational status. Patients with KCNJ5 mutations were less likely to need antihypertensive medications after adrenalectomy compared with those without mutation (36.2% versus 63.2%; P = 0.045). Conclusions The present study demonstrated the high prevalence of somatic KCNJ5 mutations in Korean patients with APA. Carriers of somatic KCNJ5 mutations were more likely to be female. Early diagnosis and better therapeutic outcomes were associated with somatic KCNJ5 mutations in APA. PMID:26807823

    Purpose The purpose of this study was to develop and validate a novel knee evaluation instrument, the Korean Knee Score (KKS), to reflect a floor life style with high knee flexion. In addition, we aimed to assess the importance of high knee flexion activity for Korean patients. Materials and Methods The KKS was developed following the guidelines of the International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine. During development step, generated items were asked to 50 patients to determine importance and obtain an impact score for each item. A total of 634 patients were included in the validation survey. Results Forty one items were generated and impact scores of each item about floor life style were higher than other items. The KKS exhibited excellent reliability (intraclass correlation coefficient=0.931) and strong internal consistency (Cronbach's α=0.973). The content validity was good, with no ceiling or floor effect. The construct, convergent, and divergent validities were good. Moderate responsiveness was evident, with a standardized response mean of 0.74. Conclusions The KKS, has good validity, reliability, and responsiveness. The KKS includes items for floor life style, which are thought more important for Korean patients. The KKS can be used as a good evaluation questionnaire for Korean knee osteoarthritis patients.

    Background The incidence and etiology of hepatocellular carcinoma (HCC) vary widely according to race and geographic regions. The insertional mutagenesis of adeno-associated virus 2 (AAV2) has recently been considered a new viral etiology of HCC. The aim of this study was to investigate the frequency and clinical characteristics of AAV2 in Korean patients with HCC. Methods A total of 289 unrelated Korean patients with HCC, including 159 Hepatitis-B-related cases, 16 Hepatitis-C-related cases, and 114 viral serology-negative cases, who underwent surgery at the Samsung Medical Center in Korea from 2009 to 2014 were enrolled in this study. The presence of AAV2 in fresh-frozen tumor tissues was investigated by DNA PCR and Sanger sequencing. The clinical and pathological characteristics of AAV2-associated HCC in these patients were compared with previous findings in French patients. Results The AAV2 detection rate in Korean patients (2/289) was very low compared with that in French patients (11/193). Similar to the French patients, the Korean patients with AAV2-related HCC showed no signs of liver cirrhosis. The Korean patients were younger than the French patients with the same AAV2-associated HCC; the ages at diagnosis of the two Korean patients were 47 and 39 yr, while the median age of the 11 French patients was 55 yr (range 43-90 yr). Conclusions AAV2-associated HCC was very rare in Korean patients with HCC. Despite a limited number of cases, this study is the first to report the clinical characteristics of Korean patients with AAV2-associated HCC. These findings suggest epidemiologic differences in viral hepatocarcinogenesis between Korean and European patients. PMID:27374713

    Isolated hypoparathyroidism (IH) shows heterogeneous phenotypes and can be caused by defects in a variety of genes. The goal of our study was to determine the clinical features and to analyze gene mutations in a large cohort of Korean patients with sporadic or familial IH. We recruited 23 patients. They showed a broad range of onset age and various values of biochemical data. Whole exome sequencing was performed on two affected cases and one unaffected individual in a family. All coding exons and exon-intron borders of GCMB, CASR, and prepro-PTH were sequenced using PCR-amplified DNA. In one family who underwent the whole exome sequencing analysis, approximately 300 single nucleotide changes emerged as candidates for genetic alteration. Among them, we identified a functional mutation in exon 2 of GCMB (C106R) in two affected cases. Besides, heterozygous gain-of-function mutations in the CASR gene were found in other subjects; D410E and P221L. We also found one single nucleotide polymorphism (SNP) in the prepro-PTH gene, five SNPs in the CASR gene, and four SNPs in the GCMB gene. The current study represents a variety of biochemical phenotypes in IH patients with the molecular genetic diagnosis of IH.

    This observational study aimed at evaluating recent superwarfarin intoxication of Korean patients. Ten patients were diagnosed as or highly suspicious for superwarfarin intoxication. Case report forms described by attending hematologists of the patients were collected and analyzed. Bleeding symptoms were varied among the patients. Patients uniformly showed prolonged prothrombin time (PT) and activated thromboplastin time (aPTT) with decreased activity of vitamin K dependent coagulation factors. Positive serum brodifacoum test results in 4 of 5 requested patients contributed to confirmatory diagnosis. Psychiatric interview revealed an attempted ingestion in one patient. High dose vitamin K1 therapy promptly corrected prolonged PT and aPTT, but hasty discontinuation caused repeated bleeding diathesis in 6 patients. Route of intoxication was unknown or not definite among 8 of 10 patients. Three patients had a possibility of environmental exposure considering their occupations: there might be intoxication by transdermal absorption or inhalation. Therefore, high dose and prolonged use of vitamin K1 therapy is necessary for effective detoxification. Further detailed investigation on environmental exposure and efforts to improve availability of the blood level test in clinic are requested. PMID:21165290

    Most of the implants used for total knee arthroplasty (TKA) in Asian patients have been produced based on anthropometry of Western people. Since anatomic features and life styles are different between Western and Eastern people, there would be ethnic differences in terms of conformity of implants to the patient's anatomy or clinical results after TKA. Therefore, surgeons in Asia are particularly interested in related surgical techniques and implant designs used in TKA for improved clinical results and patient satisfaction. In this review, we investigated the anthropometric differences of Koreans from Westerners. Koreans are of shorter stature, less weight, and smaller skeletal structure and have a higher incidence of constitutional varus alignment of the lower extremity. Moreover, compared to Westerner TKA populations, the proportion of female patients was large and primary osteoarthritis was prevalent in preoperative diagnosis in Korean TKA patients. Culturally, Koreans have life styles that demand high flexion positions of the knee such as squatting, kneeling, and cross-legged sitting. Although there were no notable differences in the complication and revision rates following TKA between Westerners and Koreans, the incidence of postoperative deep vein thrombosis and pulmonary thromboembolism was lower in Koreans than Westerners. We hope that further research on implant designs and more interest in TKA will improve outcomes in Korean patients.

    Background The etiology of chronic urticaria (CU) remains unknown in most patients. Possible causes in some cases include food, but the role of allergy to food antigens in patients with CU remains controversial. Objective The aim of this study was to evaluate the association between food allergy and CU. Methods Korean patients with CU were assessed for a previous history of food allergy that caused symptoms of CU. Blood samples were taken from 350 patients to measure food allergen-specific IgE. Based on history and laboratory results, open oral food challenge (OFC) tests were performed. Results Of 350 participants, 46 (13.1%) claimed to have experienced previous food hypersensitivity. Pork (n=16) was the main food mentioned, followed by beef (n=7), shrimp (n=6), and mackerel (n=6). We found that 73 participants (20.9%) had elevated levels of food-specific IgE, with pork (n=30), wheat (n=25), and beef (n=23) being the most common. However, when the open OFC tests were conducted in 102 participants with self-reported food hypersensitivity or raised levels of food-specific IgE, only four participants showed a positive reaction to pork (n=3) or crab (n=1). Conclusion Although some participants claimed to have a history of CU related to food intake, when an open OFC test was conducted, few of them had positive results. We therefore conclude that food allergy is an uncommon cause of chronic CU. PMID:27746634

    Background Atopic dermatitis is a global public health concern owing to its increasing prevalence and socioeconomic burden. However, few studies have assessed the economic impact of atopic dermatitis in Korea. Objective We conducted a cost analysis of atopic dermatitis and evaluated its economic impacts on individual annual disease burden, quality of life, and changes in medical expenses with respect to changes in health related-quality of life. Methods The cost analysis of atopic dermatitis was performed by reviewing the home accounting records of 32 patients. The economic impact of the disease was evaluated by analyzing questionnaires. To handle uncertainties, we compared the results with the data released by the Health Insurance Review & Assessment Board on medical costs claimed by healthcare facilities. Results The direct cost of atopic dermatitis per patient during the 3-month study period was 541,280 Korean won (KRW), and expenditures on other atopic dermatitis-related products were 120,313 KRW. The extrapolated annual direct cost (including expenditures on other atopic dermatitis-related products) per patient was 2,646,372 KRW. The estimated annual indirect cost was 1,507,068 KRW. Thus, the annual cost of illness of atopic dermatitis (i.e., direct+indirect costs) was estimated to be 4,153,440 KRW. Conclusion The annual total social cost of atopic dermatitis on a national level is estimated to be 5.8 trillion KRW. PMID:26082587

    In the combined antiretroviral therapy era, HIV-infected patients remain a vulnerable population for the onset of bloodstream infections (BSI). Worldwide, nontyphoid salmonellae, Streptococcus pneumoniae, Escherichia coli, Staphylococcus aureus and coagulase negative staphylococci are the most important pathogens. Intravenous catheter associated infection, skin-soft tissue infection and endocarditis are associated with Gram-positive bacteremia. Among the Gram-negative, nontyphoidal Salmonella have been previously correlated to sepsis. Other causes of BSI in HIV-infected patients are mycobacteria and fungi. Mycobacteria constitute a major cause of BSI in limited resource countries. Fungal BSI are not frequent and among them Cryptococcus neoformans is the most common life-threatening infection. The degree of immunosuppression remains the key prognostic factor leading to the development of BSI. PMID:26950194

    2016-01-01

    Research of the FLG mutation in various ethnic groups revealed non-overlapping mutation patterns. In addition, Japanese and Chinese atopic patients showed somewhat different mutations. These ethnic differences make the research on Korean patients mandatory; however, no systematic research on Korean atopic dermatitis (AD) patients has been performed. This study aims to investigate the genetic polymorphism of FLG in Korean atopic dermatitis patients. The study was made up of three groups including 9 Ichthyosis vulgaris (IV) patients, 50 AD patients and 55 normal controls: the ichthyosis group was incorporated due to the reported association between the FLG mutation and IV. In comparison to other sequencing methods, the overlapping long-range PCR was used. We revealed the genetic polymorphism of filaggrin in Koreans, and at the same time, we discovered nonsense mutations in p.Y1767X and p.K4022X in Korean AD patients. By using FLG sequencing techniques confirmed in this study, new mutations or genetic polymorphisms with ethnic characteristics would be detected and further larger studies of repeat number polymorphisms could be performed.

    AIM: To compare the mid-term outcomes of laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in obese Korean patients. METHODS: All consecutive patients who underwent either LSG or LRYGB with primary to treat morbid obesity between January 2011 and December 2012 were retrospectively reviewed. Patients with a body mass index (BMI) ≥ 30 kg/m2 with inadequately controlled obesity-related comorbidities (e.g., diabetes, obstructive sleep apnea, hypertension, or obesity-related arthropathy) or BMI ≥ 35 kg/m2 were considered for bariatric surgery according to the International Federation for the Surgery of Obesity-Asia Pacific Chapter Consensus statements in 2011. The decision regarding the procedure type was made on an individual basis following extensive discussion with the patient about the specific risks associated with each procedure. All operative procedures were performed laparoscopically by a single surgeon experienced in upper gastrointestinal surgeries. Baseline demographics, perioperative surgical outcomes, and postoperative anthropometric data from a prospectively established database were thoroughly reviewed and compared between the two surgical approaches. RESULTS: One hundred four patients underwent LSG, and 236 underwent LRYGB. Preoperative BMI in the LSG group was significantly higher than that of the LRYGB group (38.6 kg/m2 vs 37.2 kg/m2, P = 0.024). Patients with diabetes were more prevalent in the LRYGB group (18.3% vs 35.6%, P = 0.001). Operating time and hospital stay were significantly shorter in the LSG group compared with the LRYGB group (100 min vs 130 min, P < 0.001; 1 d vs 2 d, P = 0.003), but the incidence of perioperative complications was similar between the groups (P = 0.351). The mean percentage of excess weight loss (%EWL) was 71.2% for LRYGB, while it was 63.5% for LSG, at mean follow-up periods of 18.0 and 21.0 mo, respectively (P = 0.073). The %EWL at 1, 3, 6, 12, 18, 24, and 36 mo was equivalent

    It is well known that many Korean patients with type 2 diabetes mellitus (T2DM) were non-obese and had decreased insulin secretion in past. However, during the past three decades, lifestyles in Korea have been westernized. As a result, the prevalence of obesity, the main cause of diabetes has increased. Thus, there is still a question as to whether the main pathophysiology of current Korean T2DM is insulin resistance or an insulin secretion defect. Because various anti-diabetes medications having different mechanisms of action are currently used as therapeutics, it is important to understand which of these factors is the main physiology in the development of diabetes in Koreans. In this review, we review changes in obesity prevalence, insulin resistance and insulin secretion defects in Korean T2DM during three decades. PMID:27546870

    HIV primary resistance, drug resistance in treatment-naïve patients, is an emerging public health issue. The prevalence of HIV primary resistance mutations down to the level of 1% minor variants was investigated using ultradeep pyrosequencing (UDPS) in HIV-positive Korean blood donors and in treatment naïve chronic patients for the comparison. The entire pol region was sequenced from 25 HIV-positive blood donors, and 18 treatment-naïve chronic HIV patients. UDPS was successful in 19 blood donors and 18 chronic patients. In total, 1,011,338 sequence reads were aligned, and 28,093 sequence reads were aligned on average per sample. The prevalence of HIV primary resistance mutations in the HIV-positive blood donors and chronic HIV patients were 63.2% and 44.4% according to UDPS, respectively. Protease inhibitor (PI) drugs demonstrated different patterns in HIV-positive blood donors and chronic HIV patients, whereas non-nucleoside reverse transcriptase inhibitors (NNRTI), nucleoside reverse transcriptase inhibitors (NRTI), and integrase inhibitor (INI) drugs showed similar patterns between the two groups. Higher level of primary resistance prevalence was observed mainly because UDPS method could detect mutations in minor variants with 1-10% frequency. The higher resistance prevalence was observed in HIV-positive blood donors than in chronic patients. Considering that treatments for HIV-infected patients were recently amended to start at an earlier stage, information about degree of drug resistance to each drug between the two groups would help to establish future policies, design additional clinical trials, assess HIV patient care in Korea.

    In 2014, an H5N8 outbreak of highly pathogenic avian influenza (HPAI) occurred in South Korea. The H5N8 strain produced mild to moderate clinical signs and mortality rates in commercial chicken farms, especially Korean native chicken farms. To understand the differences between their pathogenicity in SPF chicken and Korean native chicken., we evaluated the mean bird lethal doses (BLD50) of the Korean representative H5N8 virus (A/broiler duck/Korea/Buan2/2014) The BLD50values of the H5N8 virus were 10(5.3)EID50 and 10(6.7)EID50 in SPF and Korean native chickens, respectively. In addition, the mean death time was much longer, and the viral titers in tissues of H5N8-infected chickens were significantly lower, in the Korean group than in the SPF group. These features of the H5N8 virus likely account for its mild-to-moderate pathogenicity in commercial chicken farms, especially Korean native chicken flocks, despite the fact that it is a highly pathogenic virus according to the OIE criteria. To improve current understanding and management of HPAI, pathogenic characterization of novel emerging viruses should be performed by natural route in major poultry species in each country.

    The purpose of this study was to compare clinical and virological differences between non-cytopathic (ncp) bovine viral diarrhea virus (BVDV)-1 and ncp BVDV-2 isolated from Korean field cases. Each five naïve calves were experimentally infected with Korean ncp BVDV-1 or BVDV-2 isolates. Two additional age-matched animals were used as uninfected controls. Leukocyte, lymphocyte, and platelet counts declined in all infected calves, but were significantly lower and remained decreased longer in calves infected with ncp BVDV-2 isolate. The number of monocytes was greater in calves infected with ncp BVDV-2. Flow cytometric assay showed that lymphocyte apoptosis occurred with an increase of annexin-V positive cells in all infected calves by day 6. Tumor necrosis factor alpha (TNF-α) concentration in all infected calves was lower than in control calves. In ncp BVDV-1 infected calves, interferon gamma (IFN-γ) levels in the serum were increased by day 6 compared to calves infected with ncp BVDV-2. These results demonstrated that the Korean ncp BVDV-2 isolate shows a reduced IFN-γ production, indicating prevention of the antiviral activity, and therefore promotes the development of pathological effects.

    In patients with nonvalvular atrial fibrillation (AF), the risk of stroke varies considerably according to individual clinical status. The CHA2DS2-VASc score is better than the CHADS2 score for identifying truly lower risk patients with AF. With the advent of novel oral anticoagulants (NOACs), the strategy for antithrombotic therapy has undergone significant changes due to its superior efficacy, safety and convenience compared with warfarin. Furthermore, new aspects of antithrombotic therapy and risk assessment of stroke have been revealed: the efficacy of stroke prevention with aspirin is weak, while the risk of major bleeding is not significantly different from that of oral anticoagulant (OAC) therapy, especially in the elderly. Reflecting these pivotal aspects, previous guidelines have been updated in recent years by overseas societies and associations. The Korean Heart Rhythm Society has summarized the new evidence and updated recommendations for stroke prevention of patients with nonvalvular AF. First of all, antithrombotic therapy must be considered carefully and incorporate the clinical characteristics and circumstances of each individual patient, especially with regards to balancing the benefits of stroke prevention with the risk of bleeding, recommending the CHA2DS2-VASc score rather than the CHADS2 score for assessing the risk of stroke, and employing the HAS-BLED score to validate bleeding risk. In patients with truly low risk (lone AF, CHA2DS2-VASc score of 0), no antithrombotic therapy is recommended, whereas OAC therapy, including warfarin (international normalized ratio 2-3) or NOACs, is recommended for patients with a CHA2DS2-VASc score ≥2 unless contraindicated. In patients with a CHA2DS2-VASc score of 1, OAC therapy should be preferentially considered, but depending on bleeding risk or patient preferences, antiplatelet therapy or no therapy could be permitted.

    A retrospective review of hospital admission records was conducted on patients who were admitted to the Communicable Disease Center (CDC)/Tan Tock Seng Hospital, Singapore from 1 January 2004 to 31 December 2005. There were 5 HIV patients who were admitted with dengue infection during the study period. Their symptoms were generally mild and recovery was uneventful. None of the patients developed dengue hemorrhagic fever or dengue shock syndrome. The symptoms and signs of dengue infection in HIV patients are nonspecific. It is important for healthcare workers to maintain a high index of suspicion in order to make the diagnosis. Interactions between pathogenesis pathways or with antiviral treatments may have contributed to the apparently less severe dengue infections in HIV patients. This observation needs to be explored further.

    The Neuropsychiatric Inventory (NPI) is a standardized, validated, and reliable tool to assess neuropsychiatric derangements in dementia patients. The aim of this study is to develop the Korean version of the NPI (K-NPI) and to test its reliability and usefulness in dementia patients. The subjects were 49 normal controls and 92 patients with Alzheimer's disease (43), vascular dementia (32), frontotemporal lobar degeneration (11), and other causes (6). Their caregivers familiar with the subjects' everyday behavior were interviewed with the K-NPI. In a subgroup (29/141) of the caregivers, the K-NPI was repeated for test-retest reliability, average of 23.1 days after the initial test. Prevalence rates of 12 behavioral domains in dementia patients were comparable to those of the original NPI; apathy was the most common and hallucination was the least common behavior. Total K-NPI scores correlated positively with dementia severity assessed with the Korean Mini-Mental State Examination. Test-retest reliabilities of frequencies and severities of all subscales were significantly high. Depression, anxiety, apathy, irritability, night-time behavior, and eating change were identified at very low rates in normal controls and were significantly less than those in dementia patients (p<0.001). The K-NPI, whose reliability and competency are comparable to those of the original version, may be a reliable and useful tool for measuring neuropsychiatric disturbances in Korean dementia patients.

    The purpose of the present study was to investigate the relationship between Korean language-specific dysgraphia and unilateral spatial neglect in 31 right brain stroke patients. All patients were tested for writing errors in spontaneous writing, dictation, and copying tests. The dysgraphia was classified into visuospatial omission, visuospatial destruction, syllabic tilting, stroke omission, stroke addition, and stroke tilting. Twenty-three (77.4%) of the 31 patients made dysgraphia and 18 (58.1%) demonstrated unilateral spatial neglect. The visuospatial omission was the most common dysgraphia followed by stroke addition and omission errors. The highest number of errors was made in the copying and the least was in the spontaneous writing test. Patients with unilateral spatial neglect made a significantly higher number of dysgraphia in the copying test than those without. We identified specific dysgraphia features such as a right side space omission and a vertical stroke addition in Korean right brain stroke patients. In conclusion, unilateral spatial neglect influences copy writing system of Korean language in patients with right brain stroke. PMID:25729257

    Deep vein thrombosis (DVT) and subsequent pulmonary embolism (PE) remain significant causes of morbidity, mortality in patients with spinal cord injury (SCI). Since incidence of DVT after SCI in Korean population has not been much studied, we retrospectively analyzed the medical records of 185 SCI patients admitted for acute rehabilitation unit to investigate the incidence of DVT. Color Doppler ultrasonography was performed to screen for the occurrence of DVT at the time of initial presentation to acute rehabilitation unit. Primary study outcome was the incidence of DVT. Possible risk factors for DVT including the epidemiologic characteristics, completeness of motor paralysis, cause of injury, spasticity, surgery, and active cancer were analyzed. The incidence of DVT after SCI was 27.6%. In multiple logistic regression analysis, absence of spasticity was a significant independent risk factor (P<0.05) for occurrence of DVT. Symptomatic pulmonary embolism was evident in 7 patients without an episode of sudden death. Therefore, it is concluded that the incidence of DVT after SCI in Korean patients is comparable with that in Western populations. This result suggests that pharmacologic thromboprophylaxis should be considered in Korean patients with SCI.

    Objectives: The study aimed to determine changes in laboratory data for cancer patients receiving Korean medicine (KM) care, with a focus on patients’ functional status, cancer-coagulation factors and cancer immunity. Methods: We conducted an observational study of various cancer patients in all stages admitted to the East-West Cancer Center (EWCC), Dunsan Korean Hospital of Daejeon University, from Mar. 2011 to Aug. 2011. All patients were under the center’s multi-modality Korean-medicine-based inpatient cancer care program. The hospitalization stay at EWCC ranged from 9 to 34 days. A total of 80 patients were followed in their routine hematologic laboratory screenings performed before and after hospitalization. Patients were divided into three groups depending on the status of their treatment: prevention of recurrence and metastasis group, Korean medicine (KM) treatment only group, and combination of conventional and KM treatment group. The lab reports included natural killer (NK) cell count (CD16 + CD56), fibrinogen, white blood cell (WBC), lymphocytes, monocytes, neutrophil, red blood cell (RBC), hemoglobin, platelet, Erythrocyte Sedimentation Rate (ESR), and Eastern Cooperative Oncology Group (ECOG) performance status. Results: With a Focus on patients’ functional status, cancer-coagulation factors and cancer immunity, emphasis was placed on the NK cell count, fibrinogen count, and ECOG scores. Data generally revealed decreased fibrinogen count, fluctuating NK cell count and decreased ECOG, meaning improved performance status in all groups. The KM treatment only group showed the largest decrease in mean fibrinogen count and the largest increase in mean NK cell count. However, the group’s ECOG score showed the smallest decrease, which may be due to the concentration of late-cancer-stage patients in that particular group. Conclusions: Multi-modality KM inpatient care may have positive effect on lowering the cancer coagulation factor fibrinogen, but its

In this study, we reviewed observational studies on adverse events (AEs) or complications relevant to acupuncture practice in Korean literature for assessing their reporting quality and suggested recommendations for future ones on acupuncture-related infections. Method. Electronic databases including Medline, Embase, Cochrane library, Korean studies Information Service System, DBpia, National Digital Science Library, and Korean National Assembly Library were searched until May 2015. Combination of keywords including "acupuncture" and "infection" were used for searching databases. Result. A total of 23 studies from 2,739 literature articles were identified from electronic database searching until May 2015. From this review, we found that most case studies did not report enough information for judging causality between acupuncture and the AEs (or complications) as well as appropriateness of the acupuncture practice. In addition, acupuncture experts rarely participated in the reporting of these AEs (or complications). Conclusion. Based on these limitations, we suggest a tentative recommendation for future case studies on acupuncture-related infection. We hope that this recommendation would contribute to the improvement of the reporting quality of acupuncture-related AEs (or complications) in the future.

    Genetic alterations implicated in the leukemogenesis of T cell acute lymphoblastic leukemia (T-ALL) have been identified in recent years. In this study, we investigated gene mutation profiles and prognostic implications in a series of Korean T-ALL patients. The study patients were 29 Korean patients with T-ALL; 13 adults (45 %) and 16 children (55 %; male-to-female ratio, 25:4). Clinical, hematologic, and cytogenetic findings were reviewed. We performed mutation analyses for NOTCH1, FBXW7, PHF6, and IL7R genes and survival analyses according to the mutational status. Gene mutations were identified in 66 % of the patients in our series (19/29). Eighteen patients (62 %) had NOTCH1/FBXW7 mutations. Sixteen patients (55 %) had NOTCH1 mutations including nine novel mutations, and eight patients (28 %) had known FBXW7 mutations. Eight patients (28 %; six males and two females) had PHF6 mutations including four novel mutations. Three patients (10 %) had IL7R mutations, which were all novel in-frame insertion or deletion-insertions. The gene mutation profile combined with cytogenetics and FISH study for the p16 gene detected genetic aberrations in 90 % of patients (26/29). There was no significant difference in the frequency of gene mutations between the pediatric and adult patients with T-ALL. Survival analyses suggested a favorable prognostic implication of NOTCH1 mutations in adult T-ALL. Gene mutation studies for NOTCH1, FBXW7, PHF6, and IL7R could detect genetic alterations in a majority of Korean T-ALL patients with novel mutations. We observed similar mutation profiles between adult and pediatric T-ALL, and a favorable prognostic implication of NOTCH1 mutations in adult T-ALL.

    The identification and clinical validation of cancer driver genes are essential to accelerate the translational transition of cancer genomics, as well as to find clinically confident targets for the therapeutic intervention of cancers. Here we identified recurrent LMNA-NTRK1 and TPM3-NTRK1 fusions in Korean patients with colon cancer (3 out of 147, 2%) through next-generation RNA sequencing (RNA-seq). NTRK1 fusions were mutually exclusive oncogenic drivers of colon cancer that were accompanied with in vitro potential of colony formation and in vivo tumorigenicity comparable to KM12, a human colon cancer cell line harboring TPM3-NTRK1 fusion. NTRK1-encoded TrkA protein was prevalent in 11 out of 216 Korean (5.1%) and 28 out of 472 Chinese patients (5.9%) from independent cohorts, respectively. The expression level of TrkA was significantly correlated with NTRK1 fusion (p = 0.0192), which was verified by a fluorescence in situ hybridization (FISH). Korean patients with TrkA-positive colon cancer had a marginal but significant shorter overall survival time than TrkA-negative colon cancer [hazard ratio (HR) = 0.5346, 95% confidential interval (CI) = 0.2548-0.9722, p = 0.0411]. In addition, KM12 cell line was sensitive to selective TrkA inhibitors. These results demonstrate that NTRK1 fusion is granted as a clinically relevant target for therapeutic intervention of colon cancer. PMID:26716414

    Background Rapid and complete reversal of neuromuscular blockade (NMB) is desirable at the end of surgery. Sugammadex reverses rocuronium-induced NMB by encapsulation. It is well tolerated in Caucasian patients, providing rapid reversal of moderate (reappearance of T2) rocuronium-induced NMB. We investigated the efficacy and safety of sugammadex versus neostigmine in Korean patients. Methods This randomized, safety assessor-blinded trial (NCT01050543) included Korean patients undergoing general anesthesia. Rocuronium 0.6 mg/kg was given prior to intubation with maintenance doses of 0.1-0.2 mg/kg as required. Patients received sugammadex 2.0 mg/kg or neostigmine 50 µg/kg with glycopyrrolate 10 µg/kg to reverse the NMB at the reappearance of T2, after the last rocuronium dose. The primary efficacy endpoint was the time from sugammadex or neostigmine administration to recovery of the train-of-four (TOF) ratio to 0.9. The safety of these medications was also assessed. Results Of 128 randomized patients, 118 had evaluable data (n = 59 in each group). The geometric mean (95% confidence interval) time to recovery of the TOF ratio to 0.9 was 1.8 (1.6, 2.0) minutes in the sugammadex group and 14.8 (12.4, 17.6) minutes in the neostigmine group (P < 0.0001). Sugammadex was generally well tolerated, with no evidence of residual or recurrence of NMB; four patients in the neostigmine group reported adverse events possibly indicative of inadequate NMB reversal. Conclusions Sugammadex was well tolerated and provided rapid reversal of moderate rocuronium-induced NMB in Korean patients, with a recovery time 8.1 times faster than neostigmine. These results are consistent with those reported for Caucasian patients. PMID:24427455

    The aim of this study was to identify the attitudes of elderly Korean patients toward death and dying using Q-methodology to aid in the development of basic strategies for nursing care of elderly Koreans. Thirty participants at a university hospital sorted 40 selected Q-statements on a nine-point scale. Data analysis identified three types of attitudes toward death and dying in elderly patients in Korea: religion-dependent, science-adherent, and sardonic. Religion-dependent elders are highly dependent upon religion as evidenced by their reply that they would like to rely on God and a minister the most. Science-adherent elders have great affection for life and believe in modern medical advancements. The sardonic elders regard death as the dispensation of nature so there is no need to be afraid of death and dying. This study will contribute to the understanding that nurses and other health professionals have of the perceptions of elderly Koreans about death and dying. Also, the findings may provide the basis for the development of more appropriate strategies to improve death and dying education programs of health professionals.

    To investigate the contribution of the interleukin-6 receptor (IL-6R) gene single nucleotide polymorphisms (SNPs) to the neurological status of Korean patients with ischemic stroke (IS), two SNPs of the IL-6R gene (rs4845617, 5 UTR; rs2228144, Ala31Ala) were selected. IS patients were classified into clinical phenotypes according to two well-defined scores: the National Institutes of Health Stroke Survey (NIHSS) and the Modified Barthel Index scores. There were 121 IS patients and 291 control subjects. The SNP rs4845617 significantly contributed to the neurological status of patients with IS (P = 0.011 in codominant model 2, P = 0.006 in recessive model, and P = 0.008 in log-additive model). Allele frequencies of rs4845617 and rs2228144 demonstrated no significant difference in IS patients and controls. The AG and GG haplotypes differed between the NIHSS 1 (NIHSS scores < 6) group and the NIHSS 2 (NIHSS scores ≥ 6) group in patients with IS (P = 0.014, P = 0.0024). These results suggest that rs4845617 of the IL-6R gene is associated with the neurologic status of Korean patients with IS. PMID:26955245

    [Purpose] The present study investigated a wide range of stroke patients living in South Korea using the Korean Community Health Survey raw data to determine the correlation between stroke and physical activity. [Subjects and Methods] This study used raw data from the 2012 Korean Community Health Survey. The total number of participants was 228,921; of the 4,475 stroke patients who had been diagnosed by a medical doctor or an oriental medical doctor, the data for 4,460 patients, excluding 15 whose amount of physical activity was unclear, were used in the analysis. [Results] The amount of physical activity performed by patients who had sequelae was significantly lower than that performed by patients who no longer had sequelae. Similarly, for the type of sequelae, palsy in the arms and legs, facial palsy, communication disability, swallowing or eating disability, and visual disability were associated with lower physical activity. Furthermore, as the number of sequelae increased, patients performed significantly less physical activity. [Conclusion] The findings suggest that when decisions on national policies and budgets are made, methods for increasing the physical activity of patients with a history of stroke should be considered.

    The objective of this study was to investigate the clinical and genetic features of Korean patients with facioscapulohumeral muscular dystrophy type 1 (FSHD), and assessed the impact of molecular defects on phenotypic expression. We enrolled 104 FSHD patients from 87 unrelated Korean families with D4Z4 repeat array of less than 11 copies on 4q35. Sixty-one men and forty-three women were enrolled. Median D4Z4 copy number was 4 units and 99 (95%) Korean patients with FSHD carried 1-6 units. The median age at symptom onset was 13 [interquartile range: 8-17] years old. In 100 symptomatic patients, muscle weakness began in facial muscles in 58 patients, shoulder-girdle muscles in 37, and pelvic-girdle muscles in 5. Disease severity was significantly correlated with D4Z4 copy number. In addition, women were more severely affected than men even though there were no differences in age at examination or in D4Z4 copy number between the two genders. This gender difference among Korean patients was the opposite of analysis on individuals of European ancestry. In conclusion, the present study demonstrated the new diagnostic threshold for FSHD in Koreans based on the D4Z4 repeat array size distribution from 1 to 6 units and expanded the clinical spectrum.

    Abstract To investigate whether the log odds of positive lymph nodes (LODDS) system is a more accurate prognostic tool than the number-based (pN) or ratio-based (rN) lymph node staging system in Korean patients with gastric cancer (GC). The LODDS is a recently proposed staging modality in surgical oncology. However, it is unclear whether LODDS is superior to the pN or rN system in terms of predicting the prognosis of GC patients who underwent radical gastrectomy with extended lymphadenectomy and had a greater number of retrieved lymph nodes. Clinicopathological data from 3929 patients who had undergone curative gastrectomy for GC were reviewed. In addition, overall survival rates according to pN and rN classification stratified by the LODDS were analyzed. A multivariate analysis of survival rate was performed using a Cox proportional hazard model. pN, rN, and LODDS were significantly correlated with 5-year survival rate. Spearman correlation test showed no correlation between LODDS and number of lymph nodes retrieved. The receiver operating characteristic (ROC) curves showed that the 3 staging systems had comparable prognostic accuracy (P < 0.05). Survival analysis according to pN and rN classification stratified by the LODDS staging system demonstrated that LODDS is superior to pN and rN. The LODDS is independently and significantly associated with the OS of Korean patients with GC, and its prognostic value is superior to that of the other lymph node staging systems in Korean patients.

    Background/Aims Quality of life is closely related to anemia in patients with inflammatory bowel disease (IBD). Several studies have reported on anemia in patients with IBD in Western countries. This study investigated the prevalence and clinical characteristics of anemia in Korean patients with IBD. Methods We reviewed the medical records of 92 patients with ulcerative colitis (UC) and 76 patients with Crohn's disease (CD) who were followed regularly at a single tertiary medical center in Korea between January 2003 and December 2012. Hemoglobin (Hb) thresholds used to define anemia were <13.0 g/dL in men and <12.0 g/dL in women according to the World Health Organization criteria. We chose the lowest Hb level in each year as a representative value because Hb levels changed at each examination and anemia was associated with disease deterioration. The relationship between clinical variables and lowest Hb level was assessed. Results The prevalence of anemia was 36.3% in patients with UC and 41.6% in patients with CD. Anemia in patients with CD was associated with hospital admission, 5-aminosalicylate (5-ASA) and infliximab treatment in men. Anemia in patients with UC was associated with hospital admission, oral steroid use, thiopurine and infliximab treatment in men. Conclusions The prevalence of anemia in Korean patients with IBD was comparable to that of patients in Western countries. Anemia was associated with male patients with CD who were admitted to the hospital and received medications including 5-ASA and infliximab, and men with UC who were admitted to the hospital and received medications including oral steroids, thiopurine and infliximab.

    Methylcrotonylglycinuria (MCG) is an inborn error of leucine catabolism and results from the deficiency of 3-methylcrotonyl-CoA carboxylase. Patients with MCG show a highly variable clinical phenotype, ranging from asymptomatic to severe. With the introduction of newborn screening using tandem mass spectrometry, most patients with MCG are identified in their asymptomatic neonatal periods. Owing to their fair clinical outcomes, there exists a controversy over the need for aggressive medical intervention or even for newborn screening for MCG. Our study, reporting 11 Korean MCG patients from nine unrelated families, who were identified by newborn screening or family member testing and normally developed without experiencing an metabolic crisis during the follow-up period of 2.6±1.96 years (range, 1-10 years), indicates that the aggressive medical intervention might not be needed at least for the MCG patients identified by screening program in asymptomatic period. A total of six MCCC2 mutations, but no MCCC1 mutation, were identified in 17 of 18 alleles (94.4%). p.D280Y was identified in the 12/18 alleles (66.7%), indicating a founder effect. Moreover, the rest five variants, p.S342K, p.Q496H, p.P552S, p.T556A and p.P459S, were all previously unreported. The results of our study indicate that the distinct molecular genetic characteristics exist in Korean MCG patients.

    Purpose To determine the prevalence of thyroid eye disease among dysthyroid Korean patients and to analyze the relationship between demographic data, lifestyle risk factors, and status of thyroid disease and thyroid eye disease. Methods All dysthyroid patients who visited endocrinology clinics in 24 general hospitals in Korea during a chosen one-week period were enrolled in this cross-sectional study. Data were collected during an interviewer-administered questionnaire and chart review. Demographic data, lifestyle risk factors, and status of thyroid disease variables were analyzed as risk factors using multivariable regression models to identify independent associations with thyroid eye disease. Results A total of 1,632 dysthyroid patients were included (1,301 females [79.7%] and 331 males [20.3%]). Two hundred eighty-three of these patients (17.3%) had thyroid eye disease. Multiple logistic regression analyses revealed that female gender, young age, Graves' disease, dermopathy, anti-thyroid medication treatment, and radioiodine treatment were independent risk factors for thyroid eye disease. Conclusions The lower prevalence of thyroid eye disease in dysthyroid Korean patients and the influence of gender on risk factors in this study are novel findings compared to studies performed involving Europeans. Although the risk factors for thyroid eye disease are understood in part, a more in-depth comparative study of gender and ethnic groups is needed to fully understand the biological significance of the demographic factors.

    Background: Systemic candidiasis is a major complication in neutropenic cancer patients undergoing treatment. Most systemic fungal infections emerge from endogenous microflora so the aim of the present study was to identify Candida species isolated from the different regions of body in neutropenic patients in compare with the control group. Methods: A total of 309 neutropenic cancer patients and 584 patients without cancer (control group) entered in the study. Molecular identification of clinical isolates was performed by PCR-RFLP technique. Results: Twenty-two out of 309 patients had candidiasis (7.1%). Male to female ratio was 1/1 and age ranged from 23 to 66 years. Colorectal cancer and acute myeloid leukemia (AML) were the most common cancers. Candida albicans was the most prevalent Candida species among neutropenic patients (50%) and control group (57.9%). Mortality rate in cancer patients was 13.6% in comparison with control group (5.2%). Conclusion: Since candidiasis is an important cause of morbidity and mortality in neutropenic patients, precise identification of Candida species by molecular techniques can be useful for the appropriate selection of antifungal drugs particularly in high risk patients.

    2002-03-15

    Infective endocarditis (IE) in elderly patients presents a unique diagnostic and therapeutic challenge. Atypical presentations frequently lead to delayed diagnosis and poor outcome. IE in elderly persons is somewhat more common among men. Underlying degenerative valvular disease, mitral valve prolapse, and the presence of a prosthetic valve are important risk factors predisposing elderly persons to IE. Streptococci and staphylococci are the predominant organisms, which are recovered from approximately 80% of elderly patients with IE. In older patients, IE occurs somewhat more frequently on the mitral valve than it does on the aortic valve. The presence of calcific valvular lesions and the prosthetic valves often confound the echocardiographic findings in elderly patients. A high index of suspicion and an aggressive diagnostic approach are required to ensure timely diagnosis and appropriate therapy.

    Population-based studies have reported an increased risk of suicidal ideation in patients with migraine. However, there is some controversy as to whether migraine itself is a risk factor for suicidal ideation after adjusting for psychiatric comorbidities. We calculated the frequency of suicidal ideation among patients with migraine visiting a tertiary care hospital and determined its risk factors. Patients with migraine and healthy controls completed self-report questionnaires to assess depression, anxiety, and suicidal ideation, and the frequency of suicidal ideation. Risk factors for suicidal ideation were investigated in terms of demographic, clinical, and psychiatric variables. One hundred eighty-five patients with migraine (156 females and 29 males; mean age 39.1 years) and 53 age and education-matched healthy controls participated in the study. The frequency of suicidal ideation was significantly greater in patients with migraine than healthy controls (odds ratio [OR]=5.09, 95% confidence interval [CI] 1.17-22.10, p=0.003), but this significance was not sustained after adjusting for comorbid depression and anxiety. The risk of suicidal ideation in patients with migraine was associated with lower education levels, higher frequency of migraine attacks, stronger intensity of headaches, and presence of phonophobia, chronic migraine, depression, and anxiety. The strongest predictor was depression (OR=15.36, 95% CI 5.39-43.78, p<0.001), followed by the intensity of headache while completing the questionnaire (OR=1.293, 95% CI 1.077-1.553; p=0.006). The contribution of migraine-specific variables to suicidal ideation is trivial compared to that of depression and headache intensity.

    We aimed to estimate the annual direct medical costs of South Korean systemic lupus erythematosus (SLE) patients, and their predictors. The 2010 annual direct medical costs of SLE patients in the Hanyang BAE Lupus cohort in South Korea were assessed. The information was taken directly from the hospital database and medical records, and included clinical characteristics, disease activity, organ damage, and healthcare utilization. Cost predictors were estimated with a multivariate linear regression model. A total of 749 SLE patients (92.7 % female, mean age 35.7 ± 11.3 years, mean disease duration 9.6 ± 4.9 years) were studied. Their mean annual direct medical costs amounted to USD 3305. The largest component of these costs was the cost of medication (USD 1269, 38.4 %), followed by those of diagnostic procedures and tests (USD 1177, 35.6 %). Regression analysis showed that adjusted mean SLE disease activity index score (p < 0.0001), systemic damage index (p < 0.0001), and renal (p = 0.0039) and hematologic (p = 0.0353) involvement were associated with increased direct medical costs, whereas longer disease duration was associated with lower direct medical costs. Greater disease activity and greater organ damage predict higher costs for South Korean SLE patients. Major organ involvement such as renal disorder and hematologic involvement also predicts higher costs, whereas longer duration of disease predicts lower costs.

    Objective To investigate the association of family history of stroke with functional outcomes in stroke patients in Korea. Methods A case-control study was conducted. A total of 170 patients who were admitted to a rehabilitation unit were included. Risk factors for stroke such as age, sex, diabetes mellitus, hypertension, atrial fibrillation, smoking, high blood cholesterol and homocysteine level, obesity, and family history of stroke were taken into account. Stroke subtypes were the following: large vessel infarct, small vessel infarct, embolic infarct, subarachnoid hemorrhage, and intracranial hemorrhage. Stroke severity as assessed with the National Institutes of Health Stroke Scale (NIHSS), functional outcomes using the Korean version of the Modified Barthel index (K-MBI), Functional Independence Measurement (FIM), and cognitive function using the Korean version of Mini-Mental State Examination (K-MMSE) were assessed at admission and discharge. Results Subjects with a family history of stroke were more likely to have an ischemic stroke (90.7%) than were those without a family history (70.9%). The K-MBI, FIM, NIHSS, and K-MMSE scores did not show significant differences between patients with or without family history. Conclusion Family history of stroke was significantly associated with ischemic stroke, but not with functional outcomes. Other prognostic factors of stroke were not distributed differently between patients included in this study with or without a family history of stroke. PMID:26798613

    AIM: To identify prognostic factors and to correlate APC mutations with clinical features, including extracolic manifestations. METHODS: One hundred thirty-five patients who underwent surgical procedures for familial adenomatous polyposis (FAP) were included. FAP was diagnosed when the number of adenomatous polyps was > 100. Data related to patient, extracoloic manifestations, cancer characteristics, operative procedure, follow up and surveillance were collected. APC mutation testing was performed in the 30 most recent patients. DNA was extracted from peripheral blood and polymerase chain reaction products using 31 primer pairs on APC gene were sequenced. A retrospective study was performed to investigate a causal relationship between prognosis and feature of patient. RESULTS: The mean age of the 51 patients with colorectal cancer (CRC) was older than that of those without CRC (30.5 vs 36.9, P = 0.002). Older individuals were more likely to have colon cancer at the time of FAP diagnosis [odds ratio, 4.75 (95%CI: 1.71-13.89) and 5.91(1.76-22.12) for 40-49 years and age > 50 vs age < 30). The number of confirmed deaths was 13 and the median age at death was 40 years (range, 27 to 85 years). Ten of the deaths (76.9%) were from CRC. Another cause of two cases of death were desmoid tumors (15.4%). Development of cancer on remnant rectal or ileal mucosa after surgery was not observed. The APC mutation testing revealed 23 pathogenic mutations and one likely pathogenic mutation, among which were four novel mutations. The correlation between mutational status and clinical manifestations was investigated. Mutations that could prodict poor prognosis were at codon 1309 which located on mutation cluster region, codon 1465 and codon 1507. CONCLUSION: Identification of APC mutations should aid in the diagnosis and counseling of family members in terms of early diagnosis and management of FAP. PMID:27158207

    The purpose of this study was to translate pain sensitivity questionnaires (PSQ) into the Korean language, perform a cross-cultural adaption of the PSQ, and validate the Korean version of PSQ in patients with degenerative spinal disease. The PSQ was translated forward and backward, cross-culturally adapted by 2 independent translators, and approved by an expert committee. The final Korean version of the PSQ was tested on 72 patients with degenerative spinal disease. Test-retest reliability was evaluated for 60 patients (83%) who completed the second assessment in an interval of 4 weeks. The mean PSQ-minor, PSQ-moderate, and PSQ-total (standard deviation [SD]) were 5.40 (2.02), 6.46 (1.98), and 5.93 (1.93), respectively. The PSQ-total, PSQ-minor, and PSQ-moderate of the Korean version showed very good internal consistencies determined by the Cronbach's α of 0.926, 0.869, and 0.877, respectively. For convergent validity, the PSQ scores of the Korean version showed significant correlations with pain catastrophizing scale (PCS) (r = 0.377, P = 0.002; r = 0.365, P = 0.003; r = 0.362, P = 0.003 for PSQ-total, PSQ-minor, and PSQ-moderate of the Korean version, respectively). For test-retest reliability, the intraclass correlation coefficients were 0.782 for PSQ-total, 0.752 for PSQ-minor, and 0.793 for PSQ-moderate. In conclusion, the validated Korean version of PSQ is a transculturally equivalent, reliable, and valid tool to assess individual pain sensitivity.

    Purpose The association between the red cell distribution width (RDW) and vasospastic angina (VSA) has not been elucidated. We investigated the association of the RDW with the incidence and angiographic subtypes of VSA in Korean patients. Materials and Methods A total of 460 patients who underwent intracoronary ergonovine provocation tests were consecutively enrolled and classified into two groups: the VSA group (n=147, 32.0%) and non-VSA group (n=313, 68.0%). The subjects were classified into 3 subgroups (tertiles) according to the baseline level of RDW assessed before the angiographic provocation test. Results The VSA group had a higher RDW than the non-VSA group (12.9±0.8% vs. 12.5±0.7%, p=0.013). The high RDW level demonstrated an independent association with the high incidence of VSA [second tertile: hazard ratio (HR) 1.96 (1.13–2.83), third tertile: HR 2.33 (1.22–3.47), all p<0.001]. Moreover, the highest RDW tertile level had a significant association with the prevalence of the mixed-type coronary spasm [HR 1.29 (1.03–1.59), p=0.037]. Conclusion The high level of RDW was significantly associated with the prevalence of VSA and the high-risk angiographic subtype of coronary spasm, suggesting that a proactive clinical investigation for VSA could be valuable in Korean patients with an elevated RDW.

    Background Narrowband UVB (NBUVB) is currently used to treat early mycosis fungoides (MF). There are a number of reports on the efficacy and safety of NBUVB in Caucasians, but little data is available for Asians. Objective This study was designed to evaluate the effectiveness and safety of NBUVB for early stage MF in Korean patients. Methods We enrolled 14 patients (12 men, 2 women; age range, 10~64 years) with clinically and histologically proven MF. Three patients were stage IA, and the others were stage IB. The patients received NBUVB phototherapy three times a week. The starting dose was 70% of the minimal erythema dose and was increased in 20 percent increments if the previous treatment did not cause erythema. Clinical response, total number of treatments, total cumulative dose, duration of remission and side effects were investigated. Results Eleven of 14 patients (78.6%) achieved complete remission within a mean of 15.36±5.71 weeks (range, 5~27 weeks), 31.0±7.4 treatments (range, 16~39 treatments) and a mean cumulative UVB dose of 31.31±12.16 J/cm2 (range, 11.4~46.8 J/cm2). Three of the 14 patients (21.4%) achieved a partial remission. After discontinuation of treatment, 6 of 11 patients (54.5%) with complete remission relapsed after a mean of 8.5±4.09 months. No serious adverse effects were observed except for hyperpigmentation (7/14, 50%). Conclusion Our data suggest that NBUVB therapy is safe and effective for the treatment of early stage MF in Korean patients. PMID:22148015

    We investigated the validity of the 2005 and 2010 McDonald magnetic resonance imaging (MRI) criteria for dissemination in space (DIS) to predict the conversion of clinically definite multiple sclerosis (CDMS) in 94 Korean patients with clinically isolated syndromes (CIS). The sensitivity, specificity, accuracy, positive and negative predictive values of the 2005, 2010 McDonald DIS criteria were comparable to those observed in the Caucasian population. This finding suggests that after careful exclusion of alternative explanations, particularly neuromyelitis optica (NMO) and NMO spectrum disorder (NMOSD), both the 2005 and 2010 McDonald DIS criteria are also useful to predict conversion to CDMS in Korean patients with CIS.

    As an acquired immunodeficiency, human immunodeficiency virus (HIV) infection is primarily responsible for opportunistic infections in infected patients. However, opportunistic infections also occur in individuals with human T cell lymphotrophic virus type 1 (HTLV-1) infection. Here, we report opportunistic infections in two Japanese HTLV-1-seropositive patients. The first patient was a 67-year-old male, who had cytomegalovirus infection associated with esophagogastritis and terminal ileitis. The patient was HTLV-1-positive and was diagnosed with smoldering adult T cell leukemia (ATL). High levels of serum soluble IL-2 receptor (sIL-2R; 4,304 U/mL) and an increased percentage of CD4+CD25+ T cells (75.5%) in peripheral blood were also detected. The second patient was a 78-year-old female, a known asymptomatic HTLV-1 carrier, who presented with persistent herpes zoster, followed by Pneumocystis jirovecii pneumonia. Disease progression of smoldering ATL along opportunistic infections was observed with very high levels of serum sIL-2R (14,058 U/mL) and an increased percentage of CD4+CD25+ T cells (87.2%) in peripheral blood. In patients with suspected opportunistic infections, both HTLV-1 and HIV should be considered. In HTLV-1-positive patients, an increase in the CD4+CD25+ T cell subset may have its value as a prognostic marker. PMID:26693362

    The association of vitiligo and pernicious anemia has been previously documented. The low levels of folic acid and vitamin B12 were thought to be related to vitiligo. To date, there have been very few reports about the serum levels of folic acid and vitamin B12 in patients with vitiligo. Using radioimmunoassay, we measured the serum levels of folic acid and vitamin B12 in 100 Korean patients with vitiligo. The mean serum levels of folic acid and vitamin B12 were 6.31 +/- 2.82 ng/ml and 630.25 +/- 230.94 pg/ml, respectively, in patients with vitiligo. These levels showed no significant difference compared to the normal control group, suggesting that folic acid and vitamin B12 do not appear to play a role in the pathogenesis of vitiligo.

    Wilson's disease is an inherited disease of copper metabolism leading to the toxic accumulation of copper, primarily in the liver and brain. Although the literature shows successful outcomes after proper treatment, pregnant patients with Wilson's disease still need close monitoring and management. Here, we report the case of a successful pregnancy in a Korean woman with Wilson's disease. A 33-year-old primigravid patient with Wilson's disease visited our antenatal clinic. Of her own volition, she had stopped her medication 2 years earlier. Oral zinc oxide therapy was started, and she was closely monitored throughout her pregnancy. She delivered a healthy female infant weighing 3.13 kg through a cesarean section. After delivery, the clinical course of both the mother and the baby were uneventful. We review crucial points in the treatment and the management dilemmas raised by the patient. PMID:26430668

    Cancer is a potential life-threatening illness that engenders considerable psychologic distress, requiring persistent coping for the treatment procedures. In this cross-sectional descriptive study stress levels and coping strategies of 257 cancer patients residing in South Korea are addressed. Lazarus and Folkman's theory of stress and coping was used as the theoretical framework. The data were collected from November 1999 to March 2000 by face-to-face interviews. Study participants were primarily male (62.6%) and married (91.4%). Cancer of the gastrointestinal system was the most prevalent type of cancer (31.3%). Women and the patients in the third-stage of cancer showed higher stress but less coping than other groups. Stress was negatively correlated with both problem-focused coping and emotion-focused coping. Korean patients with cancer used emotion-focused coping strategies more than problem-focused coping strategies.

    Background Decitabine was evaluated for its efficacy and safety in Korean patients with myelodysplastic syndrome with IPSS score of 0.5 or over. Design and Methods Decitabine 20 mg/m2/day was given intravenously over one hour for five consecutive days every four weeks. The primary end point was overall response rate. Results A total of 101 patients were analyzed. The International Prognostic Scoring System risk category was Intermediate-2/High in 47.5%. A median of 5 courses (range 1–18) were delivered. The overall response rate was 55.4% (13 complete responses, one partial response, 23 marrow complete responses, and 19 hematologic improvements). Forty-eight patients (47.5%) showed some hematologic improvement. With a median follow-up duration of 478 days (range 69–595), median overall survival was 17.7 months. Patients who showed hematologic improvement had significantly longer overall survival than those who did not (19.2 vs. 15.9 months, P=0.006 by landmark analysis at six months). The difference in overall survival was evident in the Intermediate-2/High risk group but not in the Intermediate-1 risk group. The progression-free survival and acute myeloid leukemia-free survival were 61.9% and 77.9% at one year, respectively. Among 489 assessable treatment courses, there were 97 fever episodes requiring intravenous antimicrobials. Conclusions Decitabine treatment was feasible and effective in Korean patients with myelodysplastic syndrome, and the overall survival was significantly longer in patients showing hematologic improvement.

    In this study, we investigated the prevalence of sexually transmitted infections (STIs) using multiplex real-time PCR assay in healthy Korean women. We also evaluated the risk factors of STIs, and compared the various factors between the STI-positive and the STI-negative groups. A total of 799 endocervical swab samples from healthy Korean women who visited our hospital for general medical check-ups during January 2012 to October 2012 were included. Eight STIs including Human papillomavirus (HPV), Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), Mycoplasma hominis (MH), Ureaplasma urealyticum (UU), Ureaplasma parvum (UP), and Trichomonas vaginalis (TV) were detected using Anyplex II STI-7 Detection assay Detection (Seegene, Seoul, Korea) and Hybrid Capture 2 High-Risk HPV DNA test (Digene Corporation, Gaithersburg, MD, USA) according manufacture's protocols. Ninety-seven (12.1%) subjects were positive for HPV. Of 393 (49.2%) subjects were infected with at least one microorganism and a total of 499 STIs were identified. Among the 393 STI-positive subjects, the proportion of single, double and triple infection was 76.3%, 20.4% and 3.3%, respectively. The median age of the STI-positive group (47 years, range 42-52) was younger than the STI-negative group (49 years, range 43-56; P < 0.001). The infection rate of HPV was significantly higher in the STI-positive group (15.8%, 62/393) than the STI-negative group (8.6%, 35/406) (P = 0.002). PMID:24462432

    Sweet potatoes (Ipomea batatas L.) are grown extensively, in tropical and temperate regions, and are important food crops worldwide. In Korea, potyviruses, including Sweet potato feathery mottle virus (SPFMV), Sweet potato virus C (SPVC), Sweet potato virus G (SPVG), Sweet potato virus 2 (SPV2), and Sweet potato latent virus (SPLV), have been detected in sweet potato fields at a high (~95%) incidence. In the present work, complete genome sequences of 18 isolates, representing the five potyviruses mentioned above, were compared with previously reported genome sequences. The complete genomes consisted of 10,081 to 10,830 nucleotides, excluding the poly-A tails. Their genomic organizations were typical of the Potyvirus genus, including one target open reading frame coding for a putative polyprotein. Based on phylogenetic analyses and sequence comparisons, the Korean SPFMV isolates belonged to the strains RC and O with >98% nucleotide sequence identity. Korean SPVC isolates had 99% identity to the Japanese isolate SPVC-Bungo and 70% identity to the SPFMV isolates. The Korean SPVG isolates showed 99% identity to the three previously reported SPVG isolates. Korean SPV2 isolates had 97% identity to the SPV2 GWB-2 isolate from the USA. Korean SPLV isolates had a relatively low (88%) nucleotide sequence identity with the Taiwanese SPLV-TW isolates, and they were phylogenetically distantly related to SPFMV isolates. Recombination analysis revealed that possible recombination events occurred in the P1, HC-Pro and NIa-NIb regions of SPFMV and SPLV isolates and these regions were identified as hotspots for recombination in the sweet potato potyviruses.

    Vitamin D is considered essential for bone and muscle health, and some studies have demonstrated the positive effects of vitamin D on metabolic diseases and cancer. Nevertheless, a high prevalence of vitamin D deficiency has been reported in various populations, regardless of country or race. However, no studies regarding the prevalence of vitamin D deficiency in Korean orthopedic patients currently exist. This cross-sectional study included 272 male and 937 female patients aged 50 years and older who were consecutively admitted to the authors' orthopedic department. Vitamin D (25-hydroxy vitamin D), bone turnover markers (osteocalcin, c-telopeptide), and bone mineral density were measured. The prevalence of vitamin D deficiency and its association with other factors were evaluated. Mean patient age was 67.2 ± 8.9 years, and mean level of vitamin D was 16.1 ± 9.1 ng/mL. Overall, 91.2% of patients had deficient (<20 ng/mL; 70.6%) or insufficient (20-30 ng/mL; 20.6%) levels of vitamin D. Vitamin D level did not vary by age group or sex. The level of vitamin D was significantly associated with osteocalcin, c-telopeptide, calcium, alkaline phosphatase, total cholesterol, triglycerides, low-density lipoprotein cholesterol, and glucose (P<.01). Vitamin D level in Korean orthopedic patients of this region was extremely low, regardless of sex and age. Although vitamin D was not directly associated with bone mineral density, there were significant associations between vitamin D and other factors related to bone health and metabolic diseases.

    Talaromyces (Penicillium) marneffei is an important pathogenic thermally dimorphic fungus causing systemic mycosis in Southeast Asia. The clinical significance of T. marneffei became evident when the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome epidemic arrived in Southeast Asia in 1988. Subsequently, a decline in the incidence of T. marneffei infection among HIV-infected patients was seen in regions with access to highly active antiretroviral therapy and other control measures for HIV. Since the 1990s, an increasing number of T. marneffei infections have been reported among non-HIV-infected patients with impaired cell-mediated immunity. Their comorbidities included primary adult-onset immunodeficiency due to anti-interferon-gamma autoantibodies and secondary immunosuppressive conditions including other autoimmune diseases, solid organ and hematopoietic stem cell transplantations, T-lymphocyte-depleting immunsuppressive drugs and novel anti-cancer targeted therapies such as anti-CD20 monoclonal antibodies and kinase inhibitors. Moreover, improved immunological diagnostics identified more primary immunodeficiency syndromes associated with T. marneffei infection in children. The higher case-fatality rate of T. marneffei infection in non-HIV-infected than HIV-infected patients might be related to delayed diagnosis due to the lack of clinical suspicion. Correction of the underlying immune defects and early use of antifungals are important treatment strategies. Clinicians should be familiar with the changing epidemiology and clinical management of T. marneffei infection among non-HIV-infected patients. PMID:26956447

    [Purpose] The purpose of this study was to establish the reliability and validity of the Short Musculoskeletal Function Assessment questionnaire, which was translated into Korean, for patients with musculoskeletal disorder. [Subjects and Methods] Fifty-five subjects (26 males and 29 females) with musculoskeletal diseases participated in the study. The Short Musculoskeletal Function Assessment questionnaire focuses on a limited range of physical functions and includes a dysfunction index and a bother index. Reliability was determined using the intraclass correlation coefficient, and validity was examined by correlating short musculoskeletal function assessment scores with the 36-item Short-Form Health Survey (SF-36) score. [Results] The reliability was 0.97 for the dysfunction index and 0.94 for the bother index. Validity was established by comparison with Korean version of the SF-36. [Conclusion] This study demonstrated that the Korean version of the Short Musculoskeletal Function Assessment questionnaire is a reliable and valid instrument for the assessment of musculoskeletal disorders.

    Mucopolysaccharidosis IVA (MPS IVA; OMIM #253000) is caused by the deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS), a lysosomal enzyme involved in the catabolism of keratan and chondroitin sulfate. In this study, we examined biochemical and genetic data from 6 Korean patients presenting with classic MPS IVA by measuring GALNS activity in peripheral blood leukocytes and skin fibroblasts. We initially identified Korean patients with MPS IVA by clinical, biochemical, and genetic analyses. We performed PCR-direct sequencing to identify molecular defects of the GALNS gene in patients and assessed the mutational statuses of family members as well as 50 healthy unrelated subjects. In silico analyses were performed to check for novel mutations. The mean age of the six female patients was 8.0 ± 5.2 years (range: 2-17 years), and were all found to have severe reductions of GALNS enzyme. A total of 12 mutant alleles were identified, corresponding to 7 different mutations. Five novel mutations were c.218A>G (p.Y73C), c.451C>A (p.P151T), c.725C>G (p.S242C), c.752G>A (p.R251Q), and c.1000C>T (p.Q334X). Two other mutations were c.1156C>T (p.R386C) and c.1243-1G>A. Two mutations, c.451C>A and c.1000C>T, accounted for 58% of all mutations in this sample.

    Abstract Evidence showing higher acute myocardial infarction (AMI) mortality rates among female compared with male inpatients has stimulated interest in whether this disparity is the result of biological factors or differences in the provision of healthcare services. We investigated the impact of sex on in-hospital mortality rates due to AMI, and evaluated the contribution of differences in the delivery of optimal medical services for AMI. We retrospectively constructed a dataset of 85,329 new patients admitted to Korean hospitals with AMI between 2003 and 2007 from the Korea National Health Insurance Claims Database. We used the claims database to provide information about treatment after admission or death for each patient. Proportionally more female than male patients aged 65 years or older had complications; however, proportionally fewer female patients underwent invasive procedures. Female patients had a higher in-hospital mortality rate than males (21.2% vs 14.6%, odds ratio [OR] 1.58, 95% confidence interval [CI] 1.52–1.64). The probability of death within 30 days after admission remained higher for females than males after adjusting for demographic characteristics and severity (OR 1.08, 95% CI 1.04–1.13). After additionally adjusting for invasive and medical management, the probability of death within 30 days did not differ between males and females (OR 1.04, 95% CI 0.99–1.08). A similar trend was revealed by an additional analysis of patients according to younger (<65 years) and older (≥65 years) age groups. The higher in-hospital mortality rates after AMI in Korean female patients was associated with a lower procedure rate. Evidence indicating that AMI symptoms differ according to sex highlights the need for health policies and public education programs that raise awareness of sex-related differences in early AMI symptoms to increase the incidence of appropriate early treatment in females.

    Background and Objectives Right heart catheterization is traditionally performed using a femoral vein approach that involves admission, bed rest, and risks of bleeding and hematoma. Recent studies have confirmed safety of the use of forearm vein for right cardiac catheterization. In the present study, we evaluated the feasibility of right cardiac catheterization via the antecubital fossa vein in Korean patients. Subjects and Methods The medical records of all patients who underwent right heart catheterization at our hospital between January 2003 and December 2014 were reviewed retrospectively. Right cardiac catheterizations via the antecubital fossa vein and the femoral vein were compared in terms of demographic data (age, sex, weight, height, and body mass index), indications for right cardiac catheterization, and procedural and outcome data (initial success rate, procedure time, compression to ambulation time, and complications). Results We reviewed 132 cases (antecubital fossa vein approach, n=37; femoral vein approach, n=95). The demographic data, initial success rate (100% vs. 100%) and procedure time (21.6±16.8 min vs. 25.6±12.6 min, p=0.14) were similar in both groups. The antecubital fossa vein group had a shorter mean compression to ambulation time than the femoral vein group (0.0 min vs. 201.2±48.1 min, p<0.01). No complications were observed in either group. Conclusion Our study indicated the ease of performance of right cardiac catheterization via the antecubital fossa vein. Thus, the antecubital fossa vein can be an alternative access site for right cardiac catheterization in Korean patients. PMID:27014351

    This study was carried out to investigate the relationship between the therapeutic effects of treatment for tic disorder and Korean medicine clinical tests, including body mass index (BMI) and heart variability rate (HRV). This study was not a clinical trial, but a data analysis of 87 tic patients who were treated for 6 months during the time period from Nov. 2010 to Jan. 2012. The clinical evaluation of the symptoms was recorded using the Korean version of the Yale Global Tic Severity Scale (YGTSS). The BMI and the HRV were measured according to a schedule, and various kinds of statistical methods were used. Among the 87 patients, the number of males was 3.34 times the number of females, and 58 patients (66.7%) had been suffering for more than 12 months. The onset age of the males was significantly lower than that of the females, and males had the symptoms longer than females had. Also, males with a family history of tics were 2.5 times as many as females, and their onset ages were substantially lower. At the first medical examinations, the average score on the YGTSS was 34.08, and it decreased linearly as the treatment progressed. After 4 and 6 months of treatment, it had decreased significantly. The YGTSS score and the period of suffering correlated positively. At the first visit, each HRV datum was in the normal range. After the 6 months' treatment, Ln (TP), Ln (LF), and Ln (HF) had dropped substantially in the normal range while Ln (VLF) and the LF/HF ratio had not changed in a meaningful way. During the treatment period, the BMI stayed relatively constant without any meaningful changes.

    Abstract Good's syndrome (GS) is a rare combination of thymoma and hypogammaglobulinemia, resulting in immunodeficiency. Patients with GS are highly susceptible to bacterial infection, particularly encapsulated bacterial infection in upper and lower respiratory tracts. Good's syndrome patients with moderate-to- severe infection are often hospitalized. Clinical features of GS patients remain to be characterized. Patients with the discharge diagnosis of GS and simultaneous infection from Peking Union Medical College Hospital between January 2001 and July 2015 were retrospectively analyzed. Among 14 hospitalized GS patients, 12 of them were admitted for severe infections. Mean patient age was 56.7 + 10.1 years. Average concentrations of serum IgG, IgA, and IgM were 2.3 + 1.9 g/L, 0.28 + 0.28 g/L, and 0.06 + 0.07 g/L, respectively. Respiratory and intestinal tracts were the most common sites for infection, which occurred in 7 and 4 patients, respectively. Pathogens identified in 10 patients included cytomegalovirus in 5 patients, Pneumocystis jirovecii, Clostridium difficile in 2 patients, Klebsiella pneumonia in 2 patients, and Streptococcus pneumonia and Hemophilus influenza in 1 patient. Ten patients were treated with antibiotics and immunoglobulin replacement. Only 1 patient who was on immunosuppressant therapy died from P. jirovecii pneumonia. Infection was the most frequent cause for hospitalization of GS patients. Both respiratory and intestinal tracts were the most common sites of infection. Cytomegalovirus and P. jirovecii represented 2 common opportunistic pathogens isolated from hospitalized GS patients with infections. PMID:26632723

    The evolution of HIV is the result of an explosive combination of factors-a high rate of mutation, replication dynamics, frequent recombination, and natural selection. To understand the evolution of the distinctive Korean HIV-1 B clade, we investigated the characteristics of the genetic variation of the HIV-1 subtype B env gene within the group of Korean men who have sex with men (MSM). From 1985 to 2005, 700 HIV-1-infected Koreans were sequenced at the V1 to V5 region of the HIV-1 env gene. In the phylogenetic analysis, 560 isolates were identified as HIV-1 subtype B, and 489 of the 560 isolates were HIV-1 Korean clade B. Based on epidemiologic investigation, 249 of 700 HIV-1-infected patients were HIV-1 subtype B-infected MSM. Interestingly, the proportion of the GPGS motif in MSM infected by Koreans was 1.6 times higher than in MSM infected by foreigners, and the genetic expansions of diversity and divergence for HIV-1 subtype B in Korean MSM were 2.1% and 2.5%, respectively. This was much lower than those observed in other countries. Therefore, our findings imply that the HIV strains in this group were closely related. This result may be helpful for understanding the evolution of the distinct HIV-1 Korean B clade.

    Depression is an important comorbidity of asthma. However, little information is available about depression and its potential impact on asthma control in Korean adult asthma patients. We aimed to estimate the prevalence and risk factors for depression in Korean adults with persistent asthma. The 127 non-elderly (20-64 yr) and 75 elderly (≥65 yr) patients with asthma were recruited. Demographic and clinical data were extracted, and the patients completed the Asthma Specific Quality of Life (AQOL) questionnaire and asthma control test (ACT). Depression status was defined using the Korean version of the Patient Health Questionnaire-9 (PHQ-9). Depression was more prevalent in non-elderly (18.9%) than in elderly patients with asthma (13.3%). Patients with depression were significantly younger, had lower economic status, shorter disease duration, poorer asthma control, and worse AQOL scores (P<0.05). Within the non-elderly group, younger age and shorter disease duration were significantly associated with depression (P<0.05). Within the elderly group, a higher body mass index and current smoking status were significantly associated with depression (P<0.05). The PHQ-9 score was significantly correlated with worse ACT and AQOL scores in both groups. In conclusion, depression is strongly associated with poor asthma control and quality of life in Korean adult asthma patients. Our results provide important clues that used to target modifiable factors which contribute to development of depression in asthma patients.

  6. Hepatitis C Virus Infection in HIV-infected Patients.

    The hepatitis C virus (HCV) is a spherical enveloped RNA virus of the Flaviviridae family, classified within the Hepacivirus genus. Since its discovery in 1989, HCV has been recognized as a major cause of chronic hepatitis and hepatic fibrosis that progresses in some patients to cirrhosis and hepatocellular carcinoma. In the United States, approximately 4 million people have been infected with HCV, and 10,000 HCV-related deaths occur each year. Due to shared routes of transmission, HCV and HIV co-infection are common, affecting approximately one third of all HIV-infected persons in the United States. In addition, HIV co-infection is associated with higher HCV RNA viral load and a more rapid progression of HCV-related liver disease, leading to an increased risk of cirrhosis. HCV infection may also impact the course and management of HIV disease, particularly by increasing the risk of antiretroviral drug-induced hepatotoxicity. Thus, chronic HCV infection acts as an opportunistic disease in HIV-infected persons because the incidence of infection is increased and the natural history of HCV infection is accelerated in co-infected persons. Strategies to prevent primary HCV infection and to modify the progression of HCV-related liver disease are urgently needed among HIV/HCV co-infected individuals.

    Purpose To describe the change of lacrimal gland volumes in Korean patients with thyroid-associated ophthalmopathy (TAO) via computed tomography (CT). Methods A retrospective review of CT images from 217 TAO patients and 135 control subjects was performed. The TAO patients were diagnosed between May 2005 and May 2014 and had a CT performed on initial presentation (330 orbital CT scans). These images were compared with 270 orbital CT scans from the control group, obtained between May 2013 and May 2014. An open source DICOM viewer was used to calculate the volume of the lacrimal gland. Results The mean volume of the lacrimal gland in TAO patients was 0.816 cm3 in the right orbit (standard deviation [SD], 0.048) and 0.811 cm3 in the left orbit (SD, 0.051), with no significant difference between right and left (p = 0.192). However, significant differences were observed between TAO patients and healthy individuals (p < 0.001). There was no significant difference between mean lacrimal gland volumes of males (0.812 cm3; SD, 0.037) and females (0.816 cm3; SD, 0.029) (p = 0.513). There was a negative correlation between gland volume and age in TAO patients (Pearson r = -0.479, p = 0.00). The subjective tearing (right: r = 0.244, p = 0.018; left: r = 0.226, p = 0.024), corneal superficial punctate keratopathy (right: r = 0.192, p = 0.040; left: r = 0.206, p = 0.036), and exophthalmometry (right: r = 0.182, p = 0.032; left: r = 0.180, p = 0.046) correlated with lacrimal gland volume. Conclusions This study is the first to use CT images to calculate the lacrimal gland volume of Korean TAO patients. In TAO patients, the lacrimal gland volume was notably increased compared to control subjects. The lacrimal gland volume decreased with age, but there was no difference between gender and no difference between left and right. The lacrimal gland volume correlated with subjective tearing, corneal superficial punctate keratopathy and exophthalmometry. PMID:27729751

    The aim of this study is to evaluate the prevalence of BK virus (BKV) infection in HIV-positive patients receiving highly active antiretroviral therapy (HAART) in our hospital. The presence of BKV was analysed in urine and plasma samples from 78 non-selected HIV-infected patients. Clinical data were recorded using a pre-established protocol. We used a nested PCR to amplify a specific region of the BKV T-large antigen. Positive samples were quantified using real-time PCR. Mean CD4 count in HIV-infected patients was 472 cells/mm3 and median HIV viral load was <50 copies/mL. BKV viraemia was detected in only 1 HIV-positive patient, but 57.7% (45 out of 78) had BKV viruria, which was more common in patients with CD4 counts>500 cells/mm3 (74.3% vs 25.7%; p=0.007). Viruria was present in 21.7% of healthy controls (5 out of 23 samples, p=0.02). All viral loads were low (<100 copies/mL), and we could not find any association between BKV infection and renal or neurological manifestations. We provide an update on the prevalence of BKV in HIV-infected patients treated with HAART. BKV viruria was more common in HIV-infected patients; however, no role for BKV has been demonstrated in this population.

    Urinary tract infections in catheterised patients continue to present a challenge in reducing healthcare-associated infection. In this article, an infection prevention and control team in one NHS trust reports on using audit results to focus attention on measures to reduce bacterial infections. Educational initiatives have an important role in reducing infection, but there is no single solution to the problem. Practice can be improved using a multi-targeted approach, peer review and clinical audit to allow for shared learning and experiences. These, along with informal education in the clinical area and more formal classroom lectures, can ultimately lead to improved patient outcomes.

    Limited data are available on inappropriate shocks in Korean patients implanted with an implantable cardioverter-defibrillator (ICD). We investigated the impact of inappropriate shocks on clinical outcomes. This retrospective, single-center study included 148 patients treated between October 1999 and June 2011. The primary outcome was a composite event of all-cause mortality or hospitalization for any cardiac reason. The median follow-up duration was 29 months (interquartile range: 8 to 53). One or more inappropriate shocks occurred in 34 (23.0%) patients. A history of atrial fibrillation was the only independent predictor of inappropriate shock (hazard ratio [HR]: 4.16, 95% confidence interval [CI]: 1.89-9.15, P < 0.001). Atrial fibrillation was the most common cause of inappropriate shock (67.7%), followed by supraventricular tachycardia (23.5%), and abnormal sensing (8.8%). A composite event of all-cause mortality or hospitalizations for any cardiac reason during follow-up was not significantly different between patients with or without inappropriate shock (inappropriate shock vs no inappropriate shock: 35.3% vs 35.4%, adjusted HR: 1.06, 95% CI: 0.49-2.29, P = 0.877). Inappropriate shocks do not affect clinical outcomes in patients implanted with an ICD, although the incidence of inappropriate shocks is high. PMID:22690092

    This descriptive cross-sectional study aimed to investigate whether malnutrition occurs in outpatients with liver cirrhosis, and to compare the nutritional status of patients with alcoholic and viral liver cirrhosis using a variety of objective measures. This study also aimed to provide useful information about nutritional education and nutritional therapies for medical teams and patients with liver cirrhosis. Sixty-six Korean men between the ages of 30 and 69 with liver cirrhosis (24 alcohol-related and 42 virus-related) were recruited from the Internal Medicine Centres, Hanyang University Hospital, Seoul, Korea. The results showed that patients with alcoholic liver cirrhosis (ALC) were significantly lower in socio-economic status than patients with viral liver cirrhosis (VLC) (P<0.05). The energy intakes (excluding alcohol-derived energy) were 1448kcal and 1769kcal in the ALC and the VLC groups, respectively (P<0.05). As well, vitamin C intake was found to be higher in the VLC group than the ALC group, yet still more than 125% of the RDA for both groups (P<0.05). Among nutritional indices, only the TSF thickness showed interaction with the aetiology and the severity of the cirrhosis (P<0.05). Thus, these findings indicate that outpatients with liver cirrhosis in this study, particularly those with alcoholic liver cirrhosis, consumed a lower energy intake than suggested, but may not have been in a status of malnutrition. Body fat is more affected than other nutritional parameters in patients with liver cirrhosis. PMID:12810412

    2016-01-01

    Objectives: The purpose of this study is to examine the magnitude of and the factors associated with the downward mobility of first-episode psychiatric patients. Methods: This study used the claims data from the Korean Health Insurance Review and Assessment Service. The study population included 19 293 first-episode psychiatric inpatients diagnosed with alcohol use disorder (International Classification of Diseases, 10th revision [ICD-10] code F10), schizophrenia and related disorders (ICD-10 codes F20-F29), and mood disorders (ICD-10 codes F30-F33) in the first half of 2005. This study included only National Health Insurance beneficiaries in 2005. The dependent variable was the occurrence of downward mobility, which was defined as a health insurance status change from National Health Insurance to Medical Aid. Logistic regression analysis was used to assess factors associated with downward drift of first-episode psychiatric patients. Results: About 10% of the study population who were National Health Insurance beneficiaries in 2005 became Medical Aid recipients in 2007. The logistic regression analysis showed that age, gender, primary diagnosis, type of hospital at first admission, regular use of outpatient clinic, and long-term hospitalization are significant predictors in determining downward drift in newly diagnosed psychiatric patients. Conclusions: This research showed that the downward mobility of psychiatric patients is affected by long-term hospitalization and medical care utilization. The findings suggest that early intensive intervention might reduce long-term hospitalization and the downward mobility of psychiatric patients. PMID:26841885

    A seasonal variation of glucose homeostasis in humans has been reported in various geographic regions. In this study, we examined seasonal variations in hemoglobin A1c (HbA1c) in patients with type 2 diabetes living in Korea. We analyzed 57,970 HbA1c values from 4,191 patients and the association of these values with ambient temperature for 3.5 yr. Overall, HbA1c exhibited its highest values from February to March and its lowest values from September to October (coefficient for cos t = -0.0743, P = 0.058) and the difference between the peak and nadir in a year was 0.16%-0.25%. A statistically significant seasonal variation was observed in the patients who were taking oral anti-diabetic drugs (OADs) without insulin treatment (coefficient for cos t = -0.0949, P < 0.05). The Spearman correlation coefficient between daily HbA1c values and the corresponding 3-month moving average ambient temperature was -0.2154 (95% confidence interval [CI]: -0.2711, -0.1580; P < 0.05). In conclusion, HbA1c values exhibited a seasonal variation in Korean patients with type 2 diabetes, with the highest values during the cold season, particularly in those who were treated with OADs, which should be taken into account in clinical practice for stable glucose control during the cold season.

    The data were presented in abstract form at the 45(th) meeting of the American Society of Nephrology, October 30-November 04 2012, San Diego, CA, USA. Circulating autoantibodies against M-type phospholipase A2 receptor (PLA2R) are important pathogenic antibodies of idiopathic membranous nephropathy (MN) in adults. However, previous studies on the clinical impact of anti-PLA2R antibodies demonstrated several limitations, including insufficient numbers of study subjects and different time points and methods for anti-PLA2R antibody measurement. To verify the clinical significance of anti-PLA2R antibodies in Korean patients with MN, we measured autoantibodies in serum samples obtained at the time of biopsy from a total of 100 patients with idiopathic MN who had not yet received immunosuppressive treatment. We detected anti-PLA2R antibody in 69 patients, and we observed that autoantibody reactivity reflected the severity of disease activity. Proteinuria and hypoalbuminemia were more severe in patients with anti-PLA2R than in those without the autoantibodies (2.95 g/g vs. 6.85 g/g, P = 0.003; 3.1 g/dL vs. 2.5 g/dL, P = 0.004, respectively). Additionally, the clinical severities worsened proportionally as the levels of anti-PLA2R antibodies increased (P = 0.015 and P for trend <0.001 for proteinuria and hypoalbuminemia, respectively). However, neither the levels nor the presence or absence of anti-PLA2R antibody showed a significant correlation with clinical outcomes, such as remission rate and time to remission. In conclusion, we observed that anti-PLA2R antibodies are highly prevalent in Korean patients with idiopathic MN and that they reflect the clinical disease activity before the administration of immunosuppressive treatment. However, the levels of anti-PLA2R antibody at the time of kidney biopsy may not predict the clinical outcomes in current clinical practice.

    Objective To evaluate the prevalence and associated factors involved in cellulitis with lymphangitis among a group of Korean patients who were being treated for lymphedema. We present our epidemiologic research and we also report a systematic review of these types of cases. Methods This was a retrospective medical record study among 1,246 patients diagnosed with lymphedema. The study was carried out between January 2006 and December 2012 at the Kosin University Gospel Hospital and Seoul National University Bundang Hospital. Cases were examined for onset time, affected site, seasonal trend, and recurrence pattern of lymphedema, lymphangitis, and cellulitis. We also evaluated the history of blood-cell culture and antibiotic use. Results Ninety-nine lymphedema patients experienced complications such as cellulitis with accompanying lymphangitis. Forty-nine patients had more than two recurrences of cellulitis with lymphangitis. The incidence and recurrence of cellulitis with lymphangitis were significantly higher in the patients with lower-extremity lymphedema. There was a significant trend toward higher cellulitis prevalence in the lower-extremity lymphedema group according to the time of lymphedema onset. Among the cellulitis with lymphangitis cases, 62 cases were diagnosed through blood-cell culture; 8 of these 62 cultures were positive for β-hemolytic streptococci. Conclusion The prevalence rate of cellulitis with lymphangitis in patients with lymphedema was 7.95%, and the prevalence of recurrent episodes was 3.93%. Especially, there was high risk of cellulitis with lymphangitis after occurrence of lower-extremity lymphedema with passage of time. Lymphedema patients should be fully briefed about the associated risks of cellulitis before treatment, and physicians should be prepared to provide appropriate preventive education. PMID:27152284

  18. Cryptococcal Infections in Non-Hiv-Infected Patients

    2013-01-01

    Infections due to Cryptococcus species occur globally and in a wide variety of hosts, ranging from those who are severely immunosuppressed to those who have phenotypically “normal” immune systems. Approximately 1 million cases of cryptococcosis occur throughout the world, and is it estimated that there are 650,000 associated deaths annually. Most of these cases occur among patients with advanced HIV disease, but a growing number occur among solid organ transplant recipients and others receiving exogenous immunosuppression, patients with innate and acquired immunodeficiency, and otherwise immunologically normal hosts. Much of our recent knowledge is solely derived from clinical experience over the last 2 to 3 decades of cryptococcosis among HIV-infected patients. However, based on recent observations, it is clear that there are substantial differences in the epidemiology, clinical features, approaches to therapy, and outcome when comparing HIV-infected to non–HIV-infected individuals who have cryptococcosis. If one carefully examines cryptococcosis in the three largest subgroups of patients based on host immune status, specifically, those with HIV, solid organ transplant recipients, and those who are non-HIV, non-transplant (NHNT) infected persons, then one can observe very different risks for infection, varied clinical presentations, long-term complications, mortality, and approaches to therapy. This article focuses on cryptococcosis in the non–HIV-infected patient, including a brief review of ongoing events in the Pacific Northwest of the United States and Canada relative to the outbreak of Cryptococcus gattii infections among a largely immunologically normal population, and highlights some of the key insights and questions which have emerged as a result of these important new observations.

    Background/Aims Peginterferon plus ribavirin remains a standard therapy for patients with chronic hepatitis C (CHC) in Korea. We investigated the efficacy and long-term outcome of peginterferon and ribavirin therapy in Korean patients with CHC, particularly in relation to the stage of liver fibrosis. Methods The incidence of sustained virological response (SVR), hepatic decompensation, hepatocellular carcinoma, and liver-related death was analyzed in 304 patients with CHC; the patients were followed up for a median of 54 months. Results Among patients with HCV genotype 1, the SVR rate was 36.7% (18/49) and 67% (69/103) for patients with and without cirrhosis, respectively (p<0.001). For patients with non-1 HCV genotypes, the SVR rates were 86.0% (37/43) in cirrhotic patients and 86.2% (94/109) in noncirrhotic patients. SVR significantly reduced the risk of liver-related death, hepatic decompensation, and hepatocellular carcinoma, which had hazard ratios of 0.27, 0.16, and 0.22, respectively (all p<0.05). However, despite the SVR rate, patients with advanced fibrosis were still at risk of developing liver-related complications. Conclusions A relatively high SVR rate was achieved by peginterferon plus ribavirin therapy in Korean patients with CHC, which improved their long-term outcomes. However, all CHC patients with advanced hepatic fibrosis should receive close follow-up observations, even after successful antiviral treatment. PMID:27114417

  20. Patient rights and healthcare-associated infection.

    The Universal Declaration of Human Rights was adopted by the United Nations in 1948, and since that time, human rights have become widely recognized and legally enforceable in many countries. Patient rights are now included in healthcare constitutions, such as that of the English National Health Service, and in professional codes of practice. Patient rights have a number of implications for the control of healthcare-associated infections (HCAI), including: (1) justification for infection control over and above economic benefit; (2) focus and emphasis on the individual patient experience; (3) identification of some of the actions taken to control infection as breaches of rights; (4) bridging professional, infection control and public health ethics; (5) a requirement to specify the conditions under which rights can be breached; and (6) grounds for those seeking compensation for HCAI. Assuring patient rights has the potential to improve the patient experience, and in so doing, improve public confidence in healthcare provision and providers.

    We report a case of CTX-M-55-type extended-spectrum β-lactamase (ESBL)-producing Shigella sonnei infection in a 27-year-old Korean woman who had traveled to China. The patient was admitted to the hospital due to abdominal pain, watery diarrhea, and fever (39.3℃). S. sonnei was isolated from her stool specimens, and the pathogen was found to be resistant to cefotaxime due to CTX-M-55-type ESBL. Insertion sequence (IS)Ecp1 was found upstream of the blaCTX-M-55 gene. The blaCTX-M-55 gene was transferred from the S. sonnei isolate to an Escherichia coli J53 recipient by conjugation. Pulsed-field gel electrophoresis and Southern blotting revealed that the blaCTX-M-55 gene was located on a plasmid of approximately 130 kb. PMID:23483349

    Purpose The purpose of this study is to identify risk factors for severe thyroid-associated orbitopathy (TAO) and compressive optic neuropathy in Korean patients. Methods This study was a retrospective comparative case series. All TAO patients who were first seen at our institution between 2005 and 2009 and who had follow-up periods of at least 6 months were included. Patients were divided into mild or moderate and severe TAO groups. Cases were also segregated based on the presence or absence of optic neuropathy. Demographics, smoking status, comorbidities, thyroid hormonal status, thyroid autoantibody levels, and clinical presentations were assessed. Results A total of 99 patients (83 with mild to moderate courses and 16 with severe courses; 90 without optic neuropathy and 9 with optic neuropathy) were included in this study. On multiple logistic regression analysis, smoking status was a predictive risk factor for a severe course of TAO and the development of optic neuropathy (odds ratios = 6.57 and 10.00, respectively). Other factors such as age, gender, free T4 level, thyroid binding-inhibiting immunoglobulin, and a history of diabetes were not predictive of severe TAO or optic neuropathy. Conclusions Although various factors may influence the severity of TAO and the development of optic neuropathy, this study showed that smoking was a risk factor for severe TAO and the development of optic neuropathy. Therefore, it is important for patients with Graves' disease to refrain from smoking. Frequent and careful observation should also be performed in current smokers, as TAO patients who smoke are susceptible to a severe course and/or optic neuropathy. PMID:21052505

    Background and Purpose Little is known about the relationships between provoking risk factors, prognosis, and optimal duration of anticoagulation in patients with cerebral venous thrombosis (CVT), especially in Asians. We aimed to investigate whether the prognosis and required duration of anticoagulation in CVT patients differ according to the provoking risk factors. Methods Prospectively recorded data from a tertiary medical center in South Korea were retrospectively reviewed. CVTs were categorized into three groups: unprovoked, those with possibly resolved provoking factors (PR), and those with persistent provoking factors (PP). The baseline characteristics, treatment, and prognosis of patients in these three groups were analyzed. Results From 2000 to 2015, 61 patients presented with CVT: 19 (31.1%) unprovoked, 11 (18.0%) with PR, and 31 (50.9%) with PP. The patients in our cohort had a slight female predominance and lower frequency of oral contraceptive use compared to Western cohorts. Median follow-up and duration of anticoagulation were 35 and 8 months, respectively. Despite the similarities in baseline characteristics, deaths (n=3; P=0.256) and recurrences (n=7; P=0.020) were observed only in the PP group. The median intervals to death and recurrence were 9 and 13 months, respectively. Death was associated with underlying disease activity, not with CVT progression. Recurrences in the PP group were associated with lack of anticoagulation (P=0.012). Conclusions Although the prognosis of CVT is generally benign in Koreans, recurrence and death were observed in patients with persistent risk factors, suggesting their need for long-term treatment with anticoagulants.

    In the last two decades, much progress has been made in the control of burn wound infection and nasocomial infections (NI) in severely burned patients. The continiually changing epidemiology is partially related to greater understanding of and improved techniques for burn patient management as well as effective hospital infection control measures. With the advent of antimicrobial chemotherapeutic agents, infection of the wound site is now not as common as, for example, urinary and blood stream infections. Universal application of early excision of burned tissues has made a substantial improvement in the control of wound-related infections in burns. Additionally, the development of new technologies in wound care have helped to decrease morbidity and mortality in severe burn victims. Many examples can be given of the successful control of wound infection, such as the application of an appropriate antibiotic solution to invasive wound infection sites with simultaneous vacuum-assisted closure, optimal preservation of viable tissues with waterjet debridement systems, edema and exudate controlling dressings impregnated with Ag (Silvercel, Aquacell-Ag). The burned patient is at high risk for NI. Invasive interventions including intravenous and urinary chateterization, and entubation pose a further risk of NIs. The use of newly designed antimicrobial impregnated chateters or silicone devices may help the control of infection in these immunocomprimised patients. Strict infection control practices (physical isolation in a private room, use of gloves and gowns during patient contact) and appropriate empirical antimicrobial therapy guided by laboratory surveillance culture as well as routine microbial burn wound culture are essential to help reduce the incidance of infections due to antibiotic resistant microorganisms.

    Patients' knowledge concerning high blood pressure (HBP) is a useful outcome measure in HBP education programs. However, valid and easy-to-use HBP knowledge assessment tools are scarce. The purpose of the study was to validate the HBP Knowledge Test (HKT) in two independent samples of Korean Americans with HBP (N=885). A total of 61% of the sample were women with a mean age of about 61 years (standard deviation=11.0) and 44% reported some college education or greater. Psychometric and item response theory analyses identified 21 items that fit a unidimensional model to form the HKT. Internal consistency was acceptable, with Cronbach's α=0.70. Construct validity testing revealed that patients with controlled BP had significantly higher HKT scores than those with uncontrolled BP (P=.012). The HKT is a simple questionnaire for assessing and monitoring HBP knowledge. It is sensitive to differences in blood pressure control status and should provide a valid, reliable, and standardized measure of HBP knowledge with wide relevance.

    Abstract Previous studies suggested that serum gamma-glutamyltransferase (GGT) levels were associated with the prevalence of cardiovascular disease (CVD) risk factors including hypertension, diabetes mellitus (DM), and metabolic syndrome (MetS) in the general population. We aimed to investigate the relationship between serum GGT levels and CVD risk factors in Korean hypertensive patients. This cross-sectional study was based on data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2011 to 2012. The analysis included 1541 hypertensive participants. Study participants were divided into groups according to tertiles of serum GGT with cutoff points of 20 and 35 U/L. Serum GGT levels were positively associated with the components of MetS (P value < 0.05, except for systolic blood pressure and high-density lipoprotein cholesterol). After adjusting for possible confounders, serum GGT levels were associated with an increased risk of MetS, high waist circumference, high triglyceride level, fasting plasma glucose, DM, and the urinary albumin-to-creatinine ratio (P = 0.001). In hypertensive patients, serum GGT levels are positively associated with major cardiovascular risk factors such as MetS, DM, and urinary albumin excretion. PMID:26683926

  7. Lower than expected hepatitis B virus infection prevalence among first generation Koreans in the U.S.: results of HBV screening in the Southern California Inland Empire

    PubMed Central

    2014-01-01

    Background Hepatitis B virus (HBV) infection is prevalent in Asian immigrants in the USA. California’s Inland Empire region has a population of approximately four million, including an estimated 19,000 first generation Koreans. Our aim was to screen these adult individuals to establish HBV serological diagnoses, educate, and establish linkage to care. Methods A community-based program was conducted in Korean churches from 11/2009 to 2/2010. Subjects were asked to complete a HBV background related questionnaire, provided with HBV education, and tested for serum HBsAg, HBsAb and HBcAb. HBsAg positive subjects were tested for HBV quantitative DNA, HBeAg and HBeAb, counseled and directed to healthcare providers. Subjects unexposed to HBV were invited to attend a HBV vaccination clinic. Results A total of 973 first generation Koreans were screened, aged 52.3y (18-93y), M/F: 384/589. Most (75%) had a higher than high school education and were from Seoul (62.2%). By questionnaire, 24.7% stated they had been vaccinated against HBV. The serological diagnoses were: HBV infected (3.0%), immune due to natural infection (35.7%), susceptible (20.1%), immune due to vaccination (40.3%), and other (0.9%). Men had a higher infection prevalence (4.9% vs. 1.7%, p = 0.004) and a lower vaccination rate (34.6% vs. 44.0%, p = 0.004) compared to women. Self-reports of immunization status were incorrect for 35.1% of subjects. Conclusions This large screening study in first generation Koreans in Southern California demonstrates: 1) a lower than expected HBV prevalence (3%), 2) a continued need for vaccination, and 3) a need for screening despite a reported history of vaccination.

    2014-01-01

    Background Many studies have shown that clinical characteristics and outcomes differ depending on pathologic variants of focal segmental glomerulosclerosis (FSGS). However, these are not well defined in Asian populations. Methods This retrospective study evaluated clinical features and outcomes of pathologic FSGS variants in 111 adult patients between January 2004 and December 2012. Primary outcome was the composite of doubling of baseline serum creatinine concentrations (D-SCr) or onset of end-stage renal disease (ESRD). Secondary outcome included complete (CR) or partial remission (PR). Results There were 70 (63.1%), 20 (18.0%), 17 (15.3%), 3 (2.7%), and 1 (0.9%) patients with not-otherwise specified (NOS), tip, perihilar, cellular, and collapsing variants, respectively. At presentation, nephrotic-range proteinuria occurred more commonly in tip lesion than in other variants. The overall 5-year renal survival rate was 76.8%. During a median follow-up of 34.5 months, only 1 (5.0%) patient with a tip lesion reached the composite end point compared to 2 (11.8%) and 12 (17.1%) patients in perihilar and NOS variants, but this difference was not statistically significant in an adjusted Cox model. However, tip lesion was associated with a significantly increased probability of achieving CR (P = 0.044). Conclusion Similar to other populations, Korean adult patients with FSGS have distinct clinical features with the exception of a rare frequency of cellular and collapsing variants. Although pathologic variants were not associated with overall outcome, the tip variant exhibited favorable outcome in terms of achieving remission. Further studies are required to delineate long-term outcome and response to treatment of the pathologic variants. PMID:24666814

    Objective The ratio of 2nd to 4th digit length (2D:4D) is a sexually dimorphic trait. Men have a relatively shorter second digit than fourth digit. This ratio is thought to be influenced by higher prenatal testosterone level or greater sensitivity to androgen. The purpose of this study is to investigate the relationship between alcohol dependence and 2D:4D in a Korean sample and whether 2D:4D can be a biologic marker in alcohol dependence. Methods In this study, we recruited 87 male patients with alcohol dependence from the alcohol center of one psychiatric hospital and 52 healthy male volunteers who were all employees in the same hospital as controls. We captured images of the right and left hands of patients and controls using a scanner and extracted data with a graphics program. We measured the 2D:4D of each hand and compared the alcohol dependence group with the control group. We analyzed these ratios using an independent-samples t-test. Results The mean 2D:4D of patients was 0.934 (right hand) and 0.942 (left hand), while the mean 2D:4D of controls was 0.956 (right hand) and 0.958 (left hand). Values for both hands were significantly lower for patients than controls (p<0.001, right hand; p=0.004, left hand). Conclusion Patients who are alcohol dependent have a significantly lower 2D:4D than controls, similar to the results of previous studies, which suggest that a higher prenatal testosterone level in the gonadal period is related to alcoholism. Furthermore, 2D:4D is a possible predictive marker of alcohol dependence. PMID:27121425

    This article reviewed & analyzed 33 studies of the Health Belief Model applied to korean chronic ill patients which were published from 1975 to 1990. The findings of analysis are as follows. The subjects of researchs are patients with various chronic illness including Pulmonary Tb., DM., Hemodialysis & Kidney Transplantation, Hypertension, etc. The type of research is retrospective survey in all studies. The measurement of health belief in all studies & sick role behavior in most studies have relied on self report. The analysis of the relationship between health belief and sick role behavior was done using correlation coefficient in most studies. To analyze empirical support for the relationship between health belief and sick role behavior, Significance ratio was computed. This ratio is value wherein the number of statistically significant findings with relationship in the expected direction for an HBM dimension are divided by total number of studies which reported significance levels for that dimension. Examination of this ratio across the 33 studies reveals susceptibility (30.3%), severity (34.4%), benefit (65.6%), barrier (50%). The following suggestions are based on the above findings and literature review. 1. It is necessary to develop the reliable, valid and standardized instrument for measurement of health beliefs. 2. In the further measurement of perceived susceptibility of the chronic ill patients. It is considering that the perceived susceptibility and perceived severity are measured together or the measurement of perceived susceptibility is eliminated. 3. Relationship between perceived severity and sick role behavior is suggested to be analized using ANOVA, chi 2 square instead of correlation coefficient. 4. Sick role behaviors should be measured by both self report and objective measurement. 5. Prospective, longitudinal survey should be needed. 6. Other factors influencing sick role behaviors of chronic ill patients should be investigated further.

    To investigate the underlying genetic influences of primary glaucoma in Korea, molecular analysis was performed in 112 sporadic cases, and results compared with healthy controls. The myocilin (MYOC) and optineurin (OPTN) genes were directly sequenced in 112 unrelated patients, including 17 with primary open-angle glaucoma, 19 with juvenile open-angle glaucoma, and 76 with normal tension glaucoma. Healthy unrelated Korean individuals (n=100) were used as the non-selected population control. A total of three MYOC and four OPTN variants potentially associated with primary glaucoma were identified in 4 and 18 patients, respectively. A novel variant of MYOC, p.Leu255Pro, was predicted to be potentially pathogenic by in silico analysis. Another, p.Thr353Ile, has been previously reported. These two missense variants were detected in patients with a family history of glaucoma. Combined heterozygous variants p.[Thr123=;Ile288=] were identified in 2 of 112 (2%) patients but not in healthy controls. Among OPTN variants, a novel variant p.Arg271Cys was identified. Homozygous p.[Thr34=;Thr34=] (4/112, 4%), homozygous p.[Met98Lys;Met98Lys] (4/112, 4%), or combined heterozygous p.[Thr34=;Arg545Gln] (9/112, 8%) was significantly associated with the development of primary glaucoma [odds ratio (OR)=8.768, 95% confidence interval (CI)=1.972–38.988; relative risk=1.818, 95% CI=1.473–2.244; P=0.001]. The present study provides insight into the genetic or haplotype variants of MYOC and OPTN genes contributing to primary glaucoma. Haplotype variants identified in the present study may be regarded as potential contributing factors of primary glaucoma in Korea. Further studies, including those on additional genes, are required to elucidate the underlying pathogenic mechanism using a larger cohort to provide additional statistical power. PMID:27485216

    Abstract Background: Critically ill patients have an increased risk of developing infections and infectious complications, sometimes followed by death. Despite a substantial investment of resources in outcomes improvement, optimum treatment for such patients remains unclear for practicing intensivists. Methods: We conducted a review that highlights the most recent developments in the prevention, diagnosis, and management of infection and the evaluation of its outcomes. The review examines the prevention of infection, such as through daily bathing with chlorhexidine and the addition of probiotics to treatment regimens, and questions the previous standards of care, including the monitoring of gastric residuals and treatment of severely ill patients with drotrecogin alfa (activated). It also discusses novel approaches to the treatment of severely ill infected patients with extra-corporeal membrane oxygenation and the earlier normalization of body temperature. Results: The development of new antibiotics continues at a slow pace, with the likelihood that alternative approaches to the management of infection, including changes in the quality of patient care, are producing needed improvements. Conclusions: Clinical outcomes of infection are improving slowly as medical teams strive for better patient care. Lack of reimbursement is unnecessary as a punitive approach to infectious diseases.

[Subjects and Methods] A total of 16 subjects were recruited from St. Vincent’s Hospital in South Korea. At each testing session, subjects completed the K-CB&M, Berg balance scale (BBS), timed up and go test (TUG), and functional reaching test. All tests were administered by a physical therapist, and subjects completed the tests in an identical standardized order during all testing sessions. [Results] The inter- and intra-rater reliability coefficients were high for most subscores, while moderate inter-rater reliability was observed for the items “walking and looking” and “walk, look, and carry”, and moderate intra-rater reliability was observed for “forward to backward walking”. There was a positive correlation between the K-CB&M and BBS and a negative correlation between the K-CB&M and TUG in the convergent validity assessments. [Conclusion] The reliability and validity of the K-CB&M was high, suggesting that clinical practitioners treating Korean patients with hemiplegia can use this material for assessing static and dynamic balance.

    Objective To evaluate Korean physiatrists' practice of performing intramuscular botulinum toxin injection in anticoagulated patients and to assess their preference in controlling the bleeding risk before injection. Methods As part of an international collaboration survey study, a questionnaire survey was administered to 100 Korean physiatrists. Physiatrists were asked about their level of experience with botulinum toxin injection, the safe international normalized ratio range in anticoagulated patients undergoing injection, their tendency for injecting into deep muscles, and their experience of bleeding complications. Results International normalized ratio <2.0 was perceived as an ideal range for performing Botulinum toxin injection by 41% of the respondents. Thirty-six respondents replied that the international normalized ratio should be lowered to sub-therapeutic levels before injection, and 18% of the respondents reported that anticoagulants should be intentionally withheld and discontinued prior to injection. In addition, 20%–30% of the respondents answered that they were uncertain whether they should perform the injection regardless of the international normalized ratio values. About 69% of the respondents replied that they did have any standardized protocols for performing botulinum toxin injection in patients using anticoagulants. Only 1 physiatrist replied that he had encountered a case of compartment syndrome. Conclusion In accordance with the lack of consensus in performing intramuscular botulinum toxin injection in anticoagulated patients, our survey shows a wide range of practices among many Korean physiatrists; they tend to avoid botulinum toxin injection in anticoagulated patients and are uncertain about how to approach these patients. The results of this study emphasize the need for formulating a proper international consensus on botulinum toxin injection management in anticoagulated patients. PMID:27152278

    Abstract Abstract Lung cancer has a high mortality rate and is often diagnosed at the metastatic stage. Gefitinib is a targeted molecular therapeutic drug used to treat patients with non-small-cell lung cancer (NSCLC). Korean herbal medicines may also have therapeutic efficacy against lung cancer, reduce the side effects associated with chemotherapy, and improve patient quality of life (QOL). This case report describes the effects of a Korean herbal medicine regimen combined with gefitinib in a patient with NSCLC and bone metastasis. The Korean herbal medicine regimen included woohwanggeosa-dan, hwanggibujeong-dan and geonchilgyebok-jeong. The computed tomography (CT) findings showed that following combination treatment, the size of the tumor was markedly decreased without serious adverse events. Moreover, the Eastern Cooperative Oncology Group (ECOG) performance status was improved and cancer-related pain was decreased. These results suggest that a combination of Korean herbal medicines and gefitinib may be an effective therapeutic option for patients with advanced NSCLC and bone metastasis. Further studies are needed to examine the mechanism and the clinical efficacy of Korean herbal medicines against NSCLC.

Molecular analysis of the FLG gene in this study showed nine null and one unclassified mutation in 13 of 81 Korean patients with atopic dermatitis (AD): five novel null mutations (i.e. p.S1405*, c.5671_5672delinsTA, p.W1947*, p.G2025* and p.E3070*); four reported null mutations (i.e. c.3321delA, p.S1515*, p.S3296* and p.K4022*); and one unclassified mutation (i.e. c.306delAAAGCACAG). These variants are nonsense, premature termination codon or in-frame deletion expected to cause loss-of-function of FLG. Genotype-phenotype correlation is not obvious in Korean AD patients with FLG null mutations. According to a review of the mutational spectra of the FLG gene in the Asian populations, FLG null mutations appeared to be unique in each population but some mutations such as p.R501*, c.3321delA, p.S1515*, p.S3296* and p.K4022* were commonly found in at least two of the selected Asian populations including Korean, Japanese, Chinese, Singaporean Chinese or Taiwanese. Further investigations on a larger group of Korean AD would be necessary to elucidate its clinical pathogenesis and mutational spectrum related to specific FLG null mutations for AD.

    From 2005 to 2013, there were 15 dengue patients aged over 60 years old who were admitted to Photharam Hospital, Ratchaburi, Thailand. Ten were females and five were males. Nine had dengue fever (DF), and 6 had dengue hemorrhagic fever (DHF). A trending shift in age group towards adults has been seen during the past decades. No deaths were seen in these elderly patients with dengue disease, indicating early recognition and effective management of these dengue patients. The trend towards higher age in dengue patients is a problem of concern, which needs further elaboration.

    Recognition of the alterations of host defense allows a rational approach to preventing associated infections. One of the most effective strategies for preventing infection in the granulocytopenic patient is the combined use of oral non-absorbable antibiotics, laminar air-flow room reverse isolation with strict housekeeping techniques, low microbial diet, sterile water, and topical antiseptics and antibiotics. The prohibitive cost, however, warrants that this system be restricted to research settings. The suppression of aerobic Gram-negative bacilli and fungi and the preservation of colonization resistance with such combinations as trimethoprim-sulfamethoxazole and nystatin show promise in preventing infection in the granulocytopenic patient. Prevention of infection in neutropenic patients also requires attention to simpler but very effective measures such as immunizations, antimicrobial prophylaxis against intracellular and nonbacterial pathogens in high-risk patients, limiting invasive diagnostic and monitoring procedures, hand-washing by all personnel between visiting patients, oral hygiene, low microbial diets, axillary and perianal swabbing, and care with venipunctures and marrow aspirates. Finally, while the recommendations for prevention of infection are likely to continue to change with resulting improvement in patient care [92, 93], a tabulation summarizing current practices can be established based on our current knowledge (Table 1).

    Counselling of patients with chronic hepatitis C infections is often limited to discussions regarding how the virus is transmitted and what can be done to decrease the risk of transmission to others. The purpose of the present study was to document the principal concerns of newly diagnosed and follow-up patients with chronic hepatitis C, and thereby enhance counselling strategies and content. Seventy newly diagnosed and 115 follow-up patients with chronic hepatitis C virus (HCV) infection were initially asked in an open-ended manner (volunteered concerns) and then to prioritize from a prepared list of seven potential concerns (prioritized concerns), to identify those concerns that were of utmost importance to them. The most common volunteered concerns of newly diagnosed patients in decreasing order were: disease progression (27%), premature death (19%), infecting family members (13%), side-effects of treatment (11%) and miscellaneous others. In decreasing order, prioritized concerns included: infecting family members, development of liver cancer, infecting others, development of cirrhosis, social stigma of having liver disease, need for liver transplant and loss of employment. The principal volunteered and prioritized concerns of follow-up patients were similar to those of newly diagnosed patients. Volunteered and prioritized concerns were relatively consistent across the different genders, age groups, ethnic backgrounds, education level, marital status, employment, modes of viral acquisition and in the case of follow-up patients, duration of follow-up. These results indicate that health care providers who focus counselling efforts exclusively on viral transmission are unlikely to address other important concerns of newly diagnosed and follow-up patients with chronic HCV infection.

    Sarcopenia-related falls and fractures are increasing worldwide due to the aging population. The purpose of this study was to 1) evaluate anthropometric characteristics related to hip fracture in Korean patients, 2) investigate sarcopenia prevalence in hip fracture (HF) and non-hip fracture (NF) groups, and 3) investigate the correlation between sarcopenia and osteoporosis. This case-control study examined 359 HF and 1,614 NF normal populations using Korea National Health and Nutrition Examination Survey data. We performed whole-body dual energy X-ray absorptiometry to analyze body composition using the skeletal muscle mass index (SMI: lean mass/height2) and bone mineral density (BMD). In the HF group, using the AWGS definition, the prevalence of sarcopenia in women and men was 44.3% and 68.2%, respectively; in the NF group, it was 7.1% and 16.1%, respectively. Lower appendicular SMI (P < 0.001), leg muscle mass (P < 0.001), and higher prevalence of sarcopenia (P < 0.001) were observed in the HF group after adjustment for age and gender. In multivariate analysis, sarcopenia (OR = 6.52; 95% CI = 4.67-9.09), age (OR = 1.15; 95% CI = 1.13-1.17), and osteoporosis (OR = 1.87; 95% CI = 1.35-2.58) were associated with the occurrence of a hip fracture. This study showed a higher prevalence of sarcopenia in patients with hip fractures compared with a normal population, and higher prevalence of sarcopenia in men. PMID:27510394

    Acute hepatitis B, caused by hepatitis B virus (HBV) strains with drug resistant mutations or pre-core/basal core promoter (PC/BCP) mutations, is a public health concern, because this infection is often associated with poor disease outcome or difficulty in therapeutic choice. The HBV genotype, the prevalence of drug resistant mutations, and PC/BCP mutations in Korean patients with acute hepatitis B were studied. From 2006 to 2008, 36 patients with acute hepatitis B were enrolled prospectively in four general hospitals. Among them, 20 showed detectable HBV DNA (median value was 4.8 log copies/mL). HBV genotyping and analysis of HBV mutations that conferred resistance against lamivudine, adefovir, or entecavir and of PC/BCP mutations were performed using highly sensitive restriction fragment mass polymorphism (RFMP) analysis. All 20 patients were infected with HBV genotype C, which causes almost all cases of chronic hepatitis B in Korea. No patient showed mutations that conferred resistance against lamivudine (L180M, M204V/I), adefovir (A181T, N236S), or entecavir (I169M, A184T/V, S202I/G, M250V/I/L). However, four patients had BCP mutations, and two had PC mutations. Platelet counts were significantly lower in the four patients with PC/BCP mutations compared to those with wild type. In this study, all acute hepatitis B patients had genotype C HBV strains with no drug resistant mutations. However, 20% showed PC/BCP mutations. This highlights the need for further study on the significance of PC/BCP mutations.

    The present study was performed to determine the incidence and predictive factors of benign renal lesions in Korean patients undergoing nephrectomy for presumed renal cell carcinoma on preoperative imaging. We analyzed the pathologic reports and medical records of 1,598 eligible patients with unilateral, nonmetastatic, and nonfamilial renal masses. Of the 1,598 renal masses, 114 (7.1%) were benign lesions, including angiomyolipoma in 47 (2.9%), oncocytoma in 23 (1.4%), and complicated cysts in 18 (1.1%) patients. On univariate analysis, the proportion of benign lesions was significantly higher in female patients, and in patients with smaller tumors, cystic renal masses, and without gross hematuria as a presenting symptom. When renal lesions were stratified by tumor size, the proportion of benign as opposed to malignant lesions decreased significantly as tumor size increased. On multivariate analysis, female gender, smaller tumor size, and cystic lesions were significantly associated with benign histological features. The findings in this large cohort of Korean patients show a lower incidence (7.1%) of benign renal lesions than those of previous Western reports. Female gender, cystic renal lesions, and smaller tumor size are independent predictors of benign histological features.

    Objective To assess the clinical usefulness of the relatively short instrument, the Korean version of the Mini-Mental State Examination (MMSE-K), for testing the association between cognition and language function in subacute post-stroke aphasia patients. Methods Medical charts of 111 post-stroke patients (65 men; age 69.6±10.0 years; 124.6±80.6 days post-onset) were reviewed retrospectively. All patients were assessed longitudinally for aphasia using the validated Korean version of the Western Aphasia Battery (K-WAB) and for cognition using the MMSE-K. Patients were categorized and analyzed according to 3 aphasia-severity clusters. Results All subscales of the K-WAB showed significant improvement in follow-up assessments in all groups (p<0.05 or p<0.01). Only the scores of orientation, language function, and total score of MMSE-K showed significant improvement in all groups (p<0.01). The more severely impaired group showed stronger Pearson correlation coefficients between cognition and language function. Additionally, comparisons between correlation coefficients showed that the association of improvement in orientation with that of fluency and AQ% (aphasia quotient %) was significant in the more severely impaired group. Conclusion Among subacute post-stroke aphasic patients, patients with more severe aphasia showed greater impairments to cognitive function; in addition, recovery of orientation may be related to recovery of language function.

    Objectives: In Korea, cancer is one of the most important causes of death. Cancer patients have sought alternative methods, like complementary and alternative medicine (CAM) together with Western medicine, to treat cancer. Also, there are many kinds of providers of CAM therapy, including providers of Korean oriental medicine therapy. The purpose of this study is to identify the behaviors of Korean oriental medicine therapy and CAM therapy providers who treat cancer patients and to provide background knowledge for establishing a new policy with the management and quality control of CAM. Methods: Structured and well organized questionnaires were made, and 350 persons were surveyed concerning the providers of CAM or Korean oriental medicine. The questionnaires were collected and analyzed. Results: The questionnaires (182) were collected. The questionnaires identified a total of 73 known providers, such as medicinal professionals or other providers of CAM suppliers, 35.6% of whom had had experience with treating cancer patients (52.6% vs. 29.6%). The treatment methods were a little different: alternative therapy and nutritional therapy being preferred by medicinal professionals and mind body modulation therapy and alternative therapy being preferred by other CAM providers. Four patients (7.4%) experienced side effects, and 6 patients (12.5%) experienced legal problems. As the method for managing the therapy, CAM providers, medicinal professionals, and other CAM providers had different viewpoints. For example, some CAM providers stated that both legislation and an official education on CAM or a national examination were needed as a first step to establish the provider’s qualifications and that as a second step, a license test was needed for quality control. To the contrary, medicinal professionals stated that a license test was needed before legislation. Conclusion: Adequate management and quality control of CAM providers is thought to involve both education and

    Hemodialysis catheter related infections (HCRI) are one of the major causes of increasing mortality, morbidity and cost of therapy in hemodialysis patients. Prevention of HCRI requires the identification of predisposing risk factors. To determine the frequency of HCRI risk factors, we studied 116 patients (54% male, mean age of 49.5+/-16 years) patients with HCRI between 2003-2004. Forty one percent of the patients were diabetic. There was a history of previous catheter placement and infection in 41% and 32% of patients, respectively. Pathogenic organisms isolated from blood cultures included Staphylococcus-aureus 42%, Coagulase-negative Staphylococci 20%, E. Coli 19%, Enterococci 7%, Streptococcus D 7%, Pseudomonas aeruginosa 4%, and Klebsiella 1%. Bacterial resistance to vancomycin and amikacin was present in 7% and 4% of the cases, respectively. Hemodialysis catheter related blood borne infections comprised 67% of the total blood-borne infections in our hospital. No significant statistical association was found between HCRI and age, gender, diabetes mellitus, serum albumin level <30 g/L, leukocyte count, erythrocyte sedimentation rate, anatomical location of catheter, mean duration of antibiotic therapy, mean catheter duration, frequency of hemodialysis sessions, pathogenic organisms, and history of previous catheter infection. We conclude that the prevalence of pathogenic organisms of HCRI were similar to previous studies. However, bacterial resistance to antibiotics was low. The mean duration of catheter usage was longer than previously reported. PMID:17237890

    Purpose To estimate the etiology and features of the eyes with rubeosis iridis among Korean patients. Materials and Methods This study is a retrospective review of 533 Korean patients with rubeosis iridis who visited an eye hospital in Seoul, Korea. We defined rubeosis iridis as visible blood vessels on the iris surface detected during a slit-lamp examination. All cases were reviewed for age at the time of diagnosis, medical history, the most likely cause of rubeosis iridis, visual acuity, and intraocular pressure. Results The most commonly observed cause of rubeosis iridis was diabetic retinopathy (DR; n = 337, 63.2%), followed by retinal vein occlusion (RVO; n = 101, 18.9%), ocular ischemic syndrome (OIS; n = 24, 4.5%), retinal detachment (n = 17, 3.2%), and uveitis (n = 15, 2.8%). The cause was classified as miscellaneous in 18 cases (3.4%); in 21 eyes (3.9%), the cause was not clear. Age at the time of rubeosis iridis diagnosis was lower in patients with DR (56.5 years) than in those with RVO (61.0 years) and OIS (64.8 years; P < 0.01). Intraocular pressure of the eyes with DR (37.3 mmHg) and RVO (39.5 mmHg) was higher than that of the eyes with OIS (25.8 mmHg; P < 0.01). Conclusion In our population-based single center study, DR was the leading cause of rubeosis iridis followed by RVO and OIS among Korean patients. The clinical characteristics of the eyes with rubeosis iridis differed according to etiology. This finding may be useful when assessing eyes with rubeosis iridis. PMID:27490797

    Little information is currently available regarding bloodstream infection (BSI) in patients with solid tumors who, for a variety of reasons, are particularly predisposed to develop this condition. In this review we focus on the incidence, epidemiology, clinical features, etiology, antimicrobial resistance, and outcomes of BSI of adult cancer patients with solid tumors. Most episodes of BSI occur in non-neutropenic patients, in whom the site of primary or metastatic tumor often serves as the portal of entry. The urinary tract and the abdomen are the most frequent sources of infection, and cholangitis is the most common recurrent source of BSI. Gram-negative bacilli are becoming the leading cause of BSI in patients with solid tumors, and the rate of multidrug resistance is increasingly being recognized. The case-fatality rate in patients with solid tumors and BSI is high, especially among those with comorbidities, advanced neoplasms, corticosteroid therapy, and shock at presentation.

    Few data have been published regarding the epidemiology and outcome of infective endocarditis (IE) in patients with chronic hepatic disease (CHD). A retrospective analysis of the Studio Endocarditi Italiano (SEI) database was performed to evaluate the epidemiology and outcome of CHD+ patients compared with CHD- patients. The diagnosis of IE was defined in accordance with the modified Duke criteria. Echocardiography, diagnosis, and treatment procedures were in accordance with current clinical practice. Among the 1722 observed episodes of IE, 300 (17.4 %) occurred in CHD+ patients. The cause of CHD mainly consisted of chronic viral infection. Staphylococcus aureus was the most common bacterial species in CHD+ patients; the frequency of other bacterial species (S. epidermidis, streptococci, and enterococci) were comparable among the two groups. The percentage of patients undergoing surgery for IE was 38.9 in CHD+ patients versus 43.7 in CHD- patients (p = 0.06). Complications were more common among CHD+ patients (77 % versus 65.3 %, p < 0.001); embolization (43.3 % versus 26.1 %, p < 0.001) and congestive heart failure (42 % versus 34.1 %, p = 0.01) were more frequent among CHD+ patients. Mortality was comparable (12.5 % in CHD- and 15 % in CHD+ patients). At multivariable analysis, factors associated with hospital-associated mortality were having an infection sustained by S. aureus, a prosthetic valve, diabetes and a neoplasia, and CHD. Being an intravenous drug user (IVDU) was a protective factor and was associated with a reduced death risk. CHD is a factor worsening the prognosis in patients with IE, in particular in patients for whom cardiac surgery was required.

    Healthcare associated infections (HAI) are a major threat to patient safety and are costly to health systems. Our goal is to predict the HAI performance of a hospital using the patients' experience responses as input. We use four classifiers, viz. random forest, naive Bayes, artificial feedforward neural networks, and the support vector machine, to perform the prediction of six types of HAI. The six types include blood stream, urinary tract, surgical site, and intestinal infections. Experiments show that the random forest and support vector machine perform well across the six types of HAI.

    Because of shared routes of transmission, hepatitis C and HIV coinfection is common in the United States, affecting 15% to 30% of HIV-infected individuals. In the era of highly effective antiretroviral therapy, hepatitis C virus (HCV)-related liver disease has emerged as a significant cause of morbidity and mortality. Accordingly, the Infectious Diseases Society of America and the American Association for the Study of Liver Disease guidelines for the management of HCV recommend that patients with HIV/HCV undergo medical evaluation for HCV-related liver disease and consideration for HCV treatment and, if indicated, orthotopic liver transplantation. However, the treatment of patients with HIV/HCV is complicated by the relatively high prevalence of medical and psychiatric comorbidities and the challenges of anti-HCV therapy in the setting of HIV disease and antiretroviral therapy. Nonetheless, recently completed randomized controlled trials provide evidence of the safety, tolerability, and efficacy of HCV treatment with pegylated interferon-alpha plus ribavirin in HIV-infected individuals. This review focuses on the epidemiology, natural history, and management of HCV in the HIV-infected patient.

    Several Western guidelines recommend the routine use of pharmacologic thromboprophylaxis for cancer surgery patients to prevent venous thromboembolism (VTE). However, the necessity of routine pharmacologic perioperative thromboprophylaxis in Asian gastric cancer (GC) patients has not been clearly determined. To determine the necessity of routine perioperative pharmacologic thromboprophylaxis in Korean gastric cancer patients, the incidence of postoperative VTE was prospectively evaluated in gastric cancer patients receiving surgery. Among 610 GC patients who had received surgery, 375 patents underwent routine duplex Doppler ultrasonography (DUS) on days 5-12 following surgery to detect VTE and then VTE-related symptoms and signs were checked at 4 weeks after surgery (cohort A). The 235 patients that declined DUS were registered to cohort B and the occurrence of postoperative VTE was retrospectively analyzed. In cohort A, symptomatic or asymptomatic VTE until 4 weeks after surgery was detected in 9 patients [2.4%; 95% confidence interval (CI); 0.9-3.9]. Tumor stage was a significant factor related to VTE development [stage I, 1.4%; stage II/III, 2.4%; stage IV, 9.7% (P = 0.008)]. In multivariate analysis, patients with stage IV had a higher postoperative VTE development [odds ratio, 8.18 (95% CI, 1.54-43.42)] than those with stage I. In cohort B, a low incidence of postoperative VTE was reaffirmed; only one postoperative VTE case (0.4%) was observed. In conclusion, the incidence of postoperative VTE in Korean GC patients was only 2.4%. Risk-stratified applications of perioperative pharmacologic thromboprophylaxis are thought to be more appropriate than the routine pharmacologic thromboprophylaxis in Korean GC patients receiving surgery.

    We try to find out the best weight values of CA125 and HE4 in a discriminant formula classifying ovarian cancer patients from benign patients. We utilize a logistic regression analysis for the early screening system of the ovarian cancer for Korean patients. We compare our system with ROMA (Risk of Ovarian Malignancy Algorithm) of Abbot corp. In view of AUC (Area under the ROC curve), sensitivity with 95% of specificity and accuracy are considered. We performed experiments based on the logistic regression analysis separated by the case of pre- and post- menopausal stages and by the stages of progression of cancer. In our experiments, we can increase about 15.6% points of sensitivity with 95% of specificity, compared to that of ROMA. In premenopausal cases, ROMA shows 93.32% of AUC value and our system shows 97.48% of AUC, 4.1% points higher than ROMA. AUC of the ROMA for premenopausal women was 93.32%, whereas the AUC of our system was 97.48%. Furthermore, the AUC of the ROMA for early-staged ovarian cancer was 91.35%, whereas the AUC of our system was 97.22%, showing that the diagnostic performance of our system was superior over that of the ROMA in Korean patient cases.

    Mutations in the glutaryl-CoA dehydrogenase gene can result in Glutaric aciduria type 1(GA 1) by accumulation of glutaric acid, 3-hydroxyglutaric acid (3-OH-GA), and glutarylcarnitine (C5DC). GA 1 is characterized by macrocephaly, subdural hemorrhage (SDH), and dystonic movement disorder after acute encephalopathic crisis. We report a Korean patient with GA1 and a novel mutation. A 16-month-old boy presented with SDH, macrocephaly, and developmental delay. In the neurologic examination, the patient had mild axial hypotonia, but otherwise normal neurologic functions. The brain MRI showed large amounts of bilateral SDH and high signal intensity in both basal ganglia and thalamus. Metabolic screening tests detected highly elevated urinary GA levels but 3-OH-glutaric acid was normal. C5DC was 0.94 μM/L (reference range < 0.3 μM/L). The patient had compound heterozygous mutations of the GCDH gene: p.Arg257Gln (c.770G>A) and p.Cys308Arg (c.922T>C). p.Cys308Arg is a novel mutation; reports of p.Arg257Gln were also rare both in Caucasians and Asian populations. In summary, we hereby report one Korean patient with GA1 with clinical, biochemical, and radiologic characteristics confirmed by genetic analysis. PMID:24795062

    Currently, there are few studies on candidaemia in the severely burned patient. These patients share the same risk factors for invasive fungal infections as other critically ill patients, but have certain characteristics that make them particularly susceptible. These include the loss of skin barrier due to extensive burns, fungal colonisation of the latter, and the use of hydrotherapy or other topical therapies (occasionally with antimicrobials).

    Currently, there are few studies on candidaemia in the severely burned patient. These patients share the same risk factors for invasive fungal infections as other critically ill patients, but have certain characteristics that make them particularly susceptible. These include the loss of skin barrier due to extensive burns, fungal colonisation of the latter, and the use of hydrotherapy or other topical therapies (occasionally with antimicrobials). In addition, the increased survival rate achieved in recent decades in critically burned patients due to the advances in treatment has led to the increase of invasive Candida infections. This explains the growing interest in making an earlier and more accurate diagnosis, as well as more effective treatments to reduce morbidity and mortality of candidaemia in severe burned patients.

    The primary aim of this study was to estimate the prevalence of BRCA1/2 mutations among familial breast cancer (BC) patients in Korea. We analyzed 775 familial BC patients who were enrolled in the Korean Hereditary Breast Cancer (KOHBRA) study and treated at 36 institutions between May 2007 and May 2010. Patients with familial BC were defined as BC patients with family histories of BC or ovarian cancer (OC) in any relatives. All probands received genetic counseling and BRCA genetic testing was performed after obtaining informed consent. The mean age of BC diagnosis was 43.6 years. The numbers of probands with family histories of BC only and OC only were 682 and 93, respectively. The overall prevalence of the BRCA mutation among familial BC patients was 21.7 % (BRCA1 9.3 % and BRCA2 12.4 %). Subgroup analyses observed prevalences of the BRCA mutation as follows: 19.6 % among patients with BC family history only (BRCA1 7.6 % and BRCA2 12.0 %) and 36.6 % among patients with OC family history only (BRCA1 21.5 % and BRCA2 15.1 %). Most of the subgroups satisfied the 10 % probability criteria to undergo BRCA testing. However, the prevalence of the BRCA mutations among subgroups that had 2 BC patients in a family with both age at diagnosis of more than 50 years old did not reach the 10 % criteria (4.1 %). Korean familial BC patients are good candidates for BRCA testing even when they have family histories of single breast cancers. However, proband age at diagnosis should be carefully considered when selecting patients for testing.

    The disparity between patients awaiting transplantation and available organs forced many patients to go overseas to receive a transplant. Few data concerning overseas transplantation in Korea are available and the Korea Society for Transplantation conducted a survey to evaluate the trend and outcome of overseas transplantation. The survey, conducted on June 2006, included 25 hospitals nationwide that followed up patients after receiving kidney transplant (KT) or liver transplant (LT) overseas. The number of KT increased from 6 in 2001 to 206 in 2005 and for LT from 1 to 261. The information about overseas transplant came mostly from other patients (57%). The mean cost for KT was $21,000 and for LT $47,000. Patients were admitted for 18.5 days for KT and 43.4 days for LT. Graft and patient survival was 96.8% and 96.5% for KT (median follow up 23.1 months). Complication occurred in 42.5% including surgical complication (5.3%), acute rejection (9.7%) and infection (21.5%). Patient survival for LT was 91.8% (median follow up 21.2 months). Complication occurred in 44.7% including 19.4% biliary complication. Overseas KT and LT increased rapidly from 2001 to 2005. Survival of patients and grafts was comparable to domestic organ transplantation, but had a high complication rate. PMID:21218024

    Severe burn patients are one subset of critically patients in which the burn injury increases the risk of infection, systemic inflammatory response and sepsis. The infections are usually related to devices and to the burn wound. Most infections, as in other critically ill patients, are preceded by colonization of the digestive tract and the preventative measures include selective digestive decontamination and hygienic measures. Early excision of deep burn wound and appropriate use of topical antimicrobials and dressings are considered of paramount importance in the treatment of burns. Severe burn patients usually have some level of systemic inflammation. The difficulty to differentiate inflammation from sepsis is relevant since therapy differs between patients with and those without sepsis. The delay in prescribing antimicrobials increases morbidity and mortality. Moreover, the widespread use of antibiotics for all such patients is likely to increase antibiotic resistance, and costs. Unfortunately the clinical usefulness of biomarkers for differential diagnosis between inflammation and sepsis has not been yet properly evaluated. Severe burn injury induces physiological response that significantly alters drug pharmacokinetics and pharmacodynamics. These alterations impact antimicrobials distribution and excretion. Nevertheless the current available literature shows that there is a paucity of information to support routine dose recommendations. PMID:27013315

    To compare the effectiveness of two drainage systems in controlling urinary tract infections (UTIs), 65 elderly home care patients with indwelling urinary catheters participated in a retrospective intervention study. The patients first used a Foley drainable bag (DB) system, followed by a nondrainable one (NDB). Both systems used a Foley catheter. Data were obtained from physicians, nurses, caregivers, and patients regarding the number of UTIs and hospitalizations that occurred when using each system. Using the DB, 65 patients had 1,395 UTIs, 27 of which required hospitalization. Using the NDB, 2 patients had 71 UTIs, 2 of which required hospitalization. The cost for the non-hospitalization UTIs with DBs was estimated at $1,153,665 compared to $57,890 with NDBs. The hospital costs with DBs were estimated at $274,170 and $15,540 with NDBs. Because DBs were used longer than NDBs (mean = 44.4 months and 8.8 months, respectively), patients who used each bag for the same period of time were compared. When these patients used NDBs they had significantly fewer UTIs (56, with one hospitalization for 7 days) than when they used DBs (242, with 10 hospitalizations for 37 days). Although the cost of purchasing the non-replaceable NDBs is greater, the use of NDBs drastically reduced levels of infection as well as the overall cost to maintain catheterized patients.

    Objective To evaluate the efficacy and safety of sorafenib for Korean patients with metastatic renal cell carcinoma (mRCC). Methods A total of 177 mRCC patients using sorafenib as first- (N = 116), second- (N = 43), and third-line (N = 18) therapies were enrolled from 11 Korean centers between 2006 and 2012. The patient characteristics, therapy duration, tumor response, disease control rate, and tolerability were assessed at baseline and at routine follow-ups, and the progression-free survival (PFS) and overall survival (OS) times and rates were analyzed. Results Among all patients, 18 (10.2%) stopped sorafenib treatment for a median of 1.7 weeks, including 15 (8.5%) who discontinued the drug, while 40 (22.6%) and 12 (6.8%) patients required dose reductions and drug interruptions, respectively. Severe adverse events (AEs) or poor compliance was observed in 64 (36.2%) patients, with 118 (7.4%) ≥grade 3 AEs. During the treatment, one myocardial infarction was observed. The number of ≥grade 3 AEs in the first-line sorafenib group was 71 (6.8% of the total 1048 AEs). During a median follow-up of 17.2 months, the radiologically confirmed best objective response rate, disease control rate, median PFS, and median OS were 22.0%, 53.0%, 6.4 months (95% confidence interval [CI], 5.2–8.9), and 32.6 months (95% CI, 27.3–63.8) for the total 177 sorafenib-treated patients, respectively, and 23.2%, 56.0%, 7.4 months (95% CI, 5.5–10.5), and not reached yet (95% CI, 1.0–31.1) for the first-line sorafenib group, respectively. Conclusions Sorafenib produced tolerable safety, with a ≥grade 3 AE rate of 7.4% and an acceptable disease control rate (53.0%) in Korean mRCC patients. PMID:26308612

    Infective endocarditis (IE) is a potentially fatal cardiac infection associated with an inhospital mortality rate of up to 22%. Fifty per cent of IE cases develop in patients with no known history of valve disease. It is therefore important to remain vigilant to the possibility of the diagnosis in patients with a febrile illness and unknown source. From a military perspective, our patients are unique due to the breadth of pathogens they are exposed to, and blood-culture-negative IE is a risk. In particular, there should be awareness of Coxiella burnetii as a possible causative pathogen. In this review we incorporate the latest consensus from systematic reviews and publications identified by a literature search through Medline. We describe the diagnosis and management of IE with particular reference to the military population.

    Filovirus infection presents many unique challenges to patient management. Currently no approved treatments are available, and the recommendations for supportive care are not evidence based. The austere clinical settings in which patients often present and the sporadic and at times explosive nature of filovirus outbreaks have effectively limited the information available to evaluate potential management strategies. This review will summarize the management approaches used in filovirus outbreaks and provide recommendations for collecting the information necessary for evaluating and potentially improving patient outcomes in the future.

    Purpose The aim of this study was to investigate the efficacy of low-molecular-weight heparin (LMWH) for the prevention of venous thromboembolism in Korean patients who underwent hip fracture surgery (HFS). Materials and Methods Prospectively, a total 181 cases were classified into the LMWH user group (116 cases) and LMWH non-user group (65 cases). Each group was sub-classified according to fracture types as follows: 81 cases of intertrochanteric fracture (group A: 49, group B: 32) and 100 cases of neck fracture (group C: 67, group D: 33). We compared the incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE) according to LMWH use. Results Of the 181 cases, four DVTs were found in the LMWH user groups (1 in group A, and 3 in group C). One case of PE was found in LMWH non-user group D. The incidences of DVT and PE showed no statistically significant differences between the LMWH user and non-user groups (p=0.298 and 0.359, respectively). In subgroup analysis, no statistically significant differences were found between groups A and B and between groups C and D. Conclusion The administration of LMWH was not effective in the prevention of venous thromboembolism and PE in the Korean patients who underwent HFS. PMID:27401653

    This study was performed to investigate the clinical characteristics of lupus cystitis and determine the risk factors and clinical outcomes of lupus cystitis in patients with systemic lupus erythematosus (SLE). We retrospectively reviewed 1064 patients at Seoul St. Mary's Hospital in Seoul, Korea, from 1998 to 2013. Twenty-four patients had lupus cystitis. Lupus cystitis was defined as unexplained ureteritis and/or cystitis as detected by imaging studies, cystoscopy, or bladder histopathology without urinary microorganisms or stones. Three-fourths of patients with lupus cystitis had concurrent lupus mesenteric vasculitis (LMV). The initial symptoms were gastrointestinal in nature for most patients (79.2%). High-dose methylprednisolone was initially administered to most patients (91.7%) with lupus cystitis. Two patients (8.3%) died of urinary tract infections. Sixty-five age- and sex-matched patients with SLE who were admitted with other manifestations were included as the control group. Patients with lupus cystitis showed a lower C3 level (p = 0.031), higher SLE Disease Activity Index score (p = 0.006), and higher ESR (p = 0.05) upon admission; more frequently had a history of LMV prior to admission (p < 0.001); and less frequently had a history of neuropsychiatric lupus (p = 0.031) than did patients with SLE but without lupus cystitis. The occurrence of lupus cystitis was associated with a history of LMV (OR, 21.794; 95% CI, 4.061-116.963). The median follow-up period was 3.4 years, and the cumulative one-year mortality rate was 20%. Complications developed in 33.3% of patients with lupus cystitis and were related to survival (log-rank p = 0.021). Our results suggest that the possibility of lupus cystitis should be considered when a patient with SLE and history of LMV presents with gastrointestinal symptoms or lower urinary tract symptoms. Development of complications in patients with lupus cystitis can be fatal. Thus, intensive treatment

Atypical cutaneous features characterized the infection. This observation, combined with the rapidity with which reinfection occurred, suggests that the natural history of CV infection may be altered in patients with underlying ichthyoses.

    Cytomegalovirus (CMV), a member of the Herpesviridae family, is an opportunistic infection with a typically benign course in the healthy host but has a more ominous course in the immunocompromised population. CMV infection commonly affects the visceral organs, particularly the respiratory and the gastrointestinal tract. CMV cutaneous lesions are rare and can be easily missed. We present a case of a 76-year-old woman presenting with a diffuse non-pruritic macular lesion with scattered vesicles and bullae, which was initially treated as a varicella zoster virus infection and herpes simplex viral infection, but was later found on biopsy to be due to cytomegalovirus. She has a history of Sjögren's syndrome, interstitial lung disease, and being on chronic immunosuppression therapy. This case highlights the importance of considering CMV infection in the differential diagnosis of vesicular skin lesions in immunocompromised patients. Based on a PubMed search for “cutaneous cytomegalovirus”, “cutaneous CMV”, “cytomegalovirus skin”, and “skin CMV” in material published in the last 20 years (from 1996 to 2016) and reviewing any applicable referenced material outside of those dates, cases of cutaneous CMV are not well documented.

    Cystatin-C, a marker of mild renal dysfunction, has been reported to be associated with cardiovascular diseases including vasospastic angina (VSA). We aimed to investigate the impact of cystatin-C level on the prevalence and angiographic characteristics of VSA in Korean patients.A total of 549 patients in the VA-KOREA (Vasospastic Angina in KOREA) registry who underwent ergonovine provocation tests were consecutively enrolled. Estimated glomerular filtration rate (eGFR) and levels of serum creatinine (Cr) and cystatin-C were assessed before angiography.The patients were classified into two groups: the VSA group (n = 149, 27.1%) and the non-VSA group (n = 400). Although eGFR and Cr levels were similar between the two groups, the VSA group had a significantly higher level of cystatin-C (P < 0.05). A high level of cystatin-C (second tertile, hazard ratio 1.432; 95% confidence interval [1.1491.805]; P = 0.026, third tertile, 1.947 [1.132-2.719]; P = 0.003) and current smoking (2.710 [1.415-4.098]; P < 0.001) were independently associated with the prevalence of VSA. Furthermore, the highest level of cystatin-C (> 0.96 ng/mL) had a significant impact on the incidence of multivessel spasm (2.608 [1.061-4.596]; P = 0.037).A high level of cystatin-C was independently associated with the prevalence of VSA and with a high-risk type of VSA in Korean patients, suggesting that proactive investigation of VSA should be considered for patients with mild renal dysfunction indicated by elevated cystatin-C.

    Background Chemerin is a novel adipokine that is associated with inflammation and adipogenesis. However, it remains unclear whether chemerin is involved in patients with cardiovascular disease. We investigated whether the serum chemerin levels of Korean patients with coronary artery disease correlated with specific cardiometabolic parameters. Methods In total, 131 patients, all of whom had coronary artery stenosis exceeding 50%, participated in this study. Their serum chemerin levels and cardiometabolic parameters were measured. The serum chemerin levels of two groups of patients were compared; those with one stenotic vessel (n=68) and those with multiple stenotic vessels, including left main coronary artery disease (n=63). Results Serum chemerin levels correlated positively with the degree of coronary artery stenosis and fasting glucose, triglyceride, total cholesterol, low density lipoprotein cholesterol, and high sensitive C-reactive protein levels. The group with multiple stenotic vessels, including left main disease, had higher chemerin levels than the group with one stenotic vessel (t=-2.129, P=0.035). Multiple binary logistic regression showed chemerin was not an independent risk factor of multiple vessel disease (odds ratio, 1.018; confidence interval, 0.997 to 1.040; P=0.091). Conclusion Serum chemerin levels have a significant correlation with several cardiometabolic risk factors and the degree of coronary artery stenosis in Korean patients with coronary artery disease. However, multiple binary logistic regression showed chemerin was not an independent risk factor of multiple vessel disease. Additional investigations are necessary to fully elucidate the role of chemerin in cardiovascular disease. PMID:21785745

    2013-09-01

    Hepatitis C virus (HCV) infection is observed in around 20% of dialysis patients and in allograft recipients and results in a significant morbidity and mortality, especially after transplantation. Its prevalence has markedly decreased in patients who are candidates for transplantation since the introduction of screening, hygiene and prevention measures, including systematic screening of blood and organ donations, use of erythropoietin, and compliance with universal hygiene rules. A liver biopsy is preferable to non-invasive biochemical and/or morphological tests of fibrosis to evaluate liver fibrosis before and even after transplantation. In HCV-infected dialyzed patients who are not candidates for renal transplantation, the indication for antiviral therapy is limited to significant fibrosis (fibrosis ≥ 2 on the METAVIR scale). Antiviral treatment should be proposed to any HCV-infected candidate for renal transplantation, whatever the baseline histopathology. The recommendation is to use standard interferon-α as monotherapy, but pegylated interferon can be used, resulting in sustained virological response, while low doses of combined ribavirin may enhance the antiviral efficacy. After transplantation, interferon-α is contra-indicated but may be used in patients for whom the benefits of antiviral treatment clearly outweigh the risks, especially that of allograft rejection. All cirrhotic patients should be screened for hepatocellular carcinoma, whose risk is enhanced by immunosuppressive regimens. Sustained suppression of necro-inflammation may result in the reversal of cirrhosis, which reduces liver-related morbidity and improves patient and allograft survival. Finally, due to the high mortality after renal transplantation, active cirrhosis must be considered to be a contraindication to kidney transplantation, but an indication to combined liver-kidney transplantation; on the contrary, inactive compensated cirrhosis may permit renal transplantation alone.

    Acute alcoholic hepatitis (AH) is a life-threatening disease and its course is often determined by infections. However, the pattern of pathogens has not been studied. We examined the microbiological pathogens that caused blood-borne infection in patients with AH. We included 32 AH patients without infection at inclusion. Patients were followed for 1 month and their infection status was recorded based on clinical records, radiologic exams and cultures of different secreta. Nine patients (28%) developed blood culture-positive infections. The agents were of heterogeneous aetiology and came from various sites of infection. Candida species accounted for three of these infections (33%). Five patients (16%) died, two of which had positive blood cultures. A high fraction was invasively infected by a heterogeneous spectrum of microbes including yeasts and commensal bacteria. This may reflect the severe immune impairment of AH and suggests thorough infection screening and an immediate broad-spectrum antibiotic approach if infection is suspected.

    This cross-sectional study sought to identify the prevalence of medication adherence and to explore the role of depression and self-efficacy on medication adherence among patients with coronary artery diseases. Participants were recruited among outpatients who successfully underwent primary percutaneous coronary intervention (PCI) with drug-eluting stent at academic medical centres in Cheonan, South Korea. Medication adherence was evaluated by the eight-item Morisky Medication Adherence Scale using a validated Korean version. Prevalence of non-adherent to medication was 60.3%. With non-depressed and high self-efficacy as reference and after adjusting for age and gender, the models showed that those with depression and low self-efficacy are more likely to be non-adherent to medication. Therefore, future studies should focus on the development of interventions designed to reduce depression and increase self-efficacy for improving patient adherence to cardiovascular medications following PCI.

    Background and Objectives We sought to determine whether an elevated homocysteine (Hcy) level is associated with a worse prognosis in Korean patients with coronary artery disease (CAD). Subjects and Methods A total of 5839 patients (60.4% male, mean age 61.3±11.2 years) with CAD were enrolled from 2000 to 2010 at Gangnam Severance Hospital. CAD was diagnosed by invasive coronary angiography. Laboratory values including Hcy level were obtained on the day of coronary angiography and analyses were performed shortly after sampling. Patients were divided into two groups according to their Hcy levels. Baseline risk factors, coronary angiographic findings, length of follow-up, and composite endpoints including cardiac death (CD) and non-fatal myocardial infarction (NFMI) were recorded. 1:1 propensity score matched analysis was also performed. Results Over a mean follow-up period of 4.4±2.5 years, there were 132 composite endpoints (75 CD and 57 NFMI) with an event rate of 2.3%. Mean Hcy level was 9.9±4.3 µmol/L (normal Hcy 7.9±1.5 µmol/L and elevated Hcy 13.9±5.1 µmol/L). Kaplan-Meier survival analysis showed an association of elevated Hcy level with worse prognosis (p<0.0001). In addition, a multivariate Cox regression analysis showed an association of elevated Hcy level with worse prognosis for both the entire cohort (hazard ratio [HR] 2.077, 95% confidence interval [CI] 1.467-2.941, p<0.0001) and the propensity score matched cohort (HR 1.982, 95% CI 1.305-3.009, p=0.001). Conclusion Elevated Hcy level is associated with worse outcomes in Korean patients with CAD. PMID:27014345

    Diagnostic delay frequently occurs in Crohn's disease (CD) patients because of diagnostic limitations. However, diagnostic delay and its related factors remain poorly defined. Therefore, we aimed to identify the predictors associated with diagnostic delay and to evaluate the impact of diagnostic delay on clinical course in a Korean CD patient cohort. We performed a multicenter retrospective analysis of 1,047 CD patients registered in the Crohn's Disease Clinical Network and Cohort study in Korea. The mean interval of diagnostic delay was 16.0 ± 33.1 months. Multivariate analysis showed that older age at diagnosis (≥40 years) (p = 0.014), concomitant upper gastrointestinal (UGI) disease (p = 0.012) and penetrating disease behavior at diagnosis (p = 0.001) were positively associated with long diagnostic delay (≥18 months). During the longitudinal follow-up, long diagnostic delay was independently predictive of further development of intestinal stenosis (hazard ratio [HR], 1.43; 95% confidence interval [CI], 1.07-1.93; p = 0.017), internal fistulas (HR, 1.62; 95% CI, 1.12-2.33; p = 0.011), and perianal fistulas (HR, 1.38; 95% CI, 1.06-1.80; p = 0.016). However, as for the risk of abscess formation, bowel perforation, and CD-related abdominal surgery, no significant association with diagnostic delay was observed. Older age at diagnosis, UGI involvement, and penetrating behavior are associated with long diagnostic delay in Korean CD patients. Moreover, diagnostic delay is associated with an increased risk of CD-related complications such as intestinal stenosis, internal fistulas, and perianal fistulas.

    Despite the huge advance that antiretroviral therapy represents for the prognosis of infection by the human immunodeficiency virus (HIV), opportunistic infections (OIs) continue to be a cause of morbidity and mortality in HIV-infected patients. OIs often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an OI. The present article updates our previous guidelines on the prevention and treatment of various OIs in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome.

    Objectives To explore perceptions and experiences of patients with chronic fatigue with traditional Korean medicine (TKM) and their motivation for choosing TKM. Design Qualitative, one-on-one, in-depth interview study. Setting Primary TKM hospitals in Seoul, Incheon and Daejeon, South Korea. Results 15 patients with chronic fatigue were interviewed in this study. Patients with chronic fatigue experienced physical and psychological symptoms that resulted in severe difficulties associated with routine daily activities. The motivations for choosing TKM were primarily dissatisfaction with conventional medicine and previous positive experiences with TKM. While undergoing TKM treatment, patients found that TKM practitioners considered fatigue to be a treatable illness; also, patients felt comfortable with the doctor–patient relationship in TKM. Conclusions Healthcare providers need to be concerned about the symptoms of chronic fatigue to a degree that is in line with the patient's own perceptions. Korean patients with chronic fatigue choose TKM as an alternative to fulfil their long-term needs that were unmet by conventional medicine, and they are greatly positively influenced by TKM. TKM may present a possible therapy to alleviate symptoms of diseases that conventional medicine does not address and is an approach that has a considerable effect on Korean patients. PMID:26351179

    Background Guidelines for esophagogastroduodenoscopy (EGD) in the West allow the continued use of warfarin under therapeutic international normalized ratio (INR) level. In Korea, no guidelines have been issued regarding warfarin treatment before EGD. The authors surveyed Korean cardiac surgeons about how Korean cardiac surgeons handle warfarin therapy before EGD using a questionnaire. Participants were requested to make decisions regarding the continuation of warfarin therapy in two hypothetical cases. Methods The questionnaire was administered to cardiac surgeons and consisted of eight questions, including two case scenarios. Results Thirty-six cardiac surgeons at 28 hospitals participated in the survey, and 52.7% of the participants chose to stop warfarin before EGD in aortic valve replacement patients without risk factors for thromboembolism. When the patient’s INR level was 2, 31% of the participants indicated that they would choose to continue warfarin therapy. For EGD with biopsy, 72.2% of the participants chose warfarin withdrawal, and 25% of the participants chose heparin replacement. In mitral valve replacement patients, 47.2% of the participants chose to discontinue warfarin, and 22.2% of the participants chose heparin replacement. For EGD with biopsy in patients with a mitral valve replacement, 58.3% of the participants chose to stop warfarin, and 41.7% of the participants chose heparin replacement. Conclusion This study demonstrated that attitudes regarding warfarin treatment for EGD are very different among Korean surgeons. Guidelines specific to the Korean population are required.

    The purpose of this study was to compare the effects of Korean mindfulness-based stress reduction (K-MBSR), walking, and patient education regarding diabetes mellitus (DM) on stress response, glycemic control, and vascular inflammation in patients with diabetes mellitus. A cluster randomized trial including 56 adults with diabetes mellitus (K-MBSR group = 21, walking group = 18, patient education group = 17) was conducted between 13 July and 14 September 2012. The questionnaire included the Diabetes Distress Scale and Perceived Stress Response Inventory. Fasting blood samples were used to measure levels of cortisol, blood glucose, plasminogen activator inhibitor-1 (PAI-1), and tissue plasminogen activator (t-PA). There were no statistically significant differences between the effects of K-MBSR, walking, and patient education on stress, glycemic control, or vascular inflammation. However, in the K-MBSR and walking groups, significant reductions in the levels of serum cortisol and PAI-1 were observed. A significant reduction in psychological responses to stress was observed in the walking and patient education groups. Longitudinal studies could provide better insight into the impact of K-MBSR, walking, and patient education on health outcomes in adults with diabetes mellitus.

    Many Korean American persons have hypertension, but competing life priorities often prevent them from attending health-promotion educational activities. Using principles of community-based participatory research, the authors conducted a prospective clinical trial to determine the effectiveness of a mailed vs an in-class culturally tailored education intervention. A total of 380 hypertensive Korean American persons from the Baltimore/Washington area were assigned to a more intense in-class education group or a less intensive mail education group. Evaluation of postintervention blood pressure (BP) outcomes revealed that significant reductions in systolic BP (13.3 mm Hg and 16.1 mm Hg, respectively) and diastolic BP (9.5 mm Hg and 10.9 mm Hg) and increases in BP control rates (42.3% and 54.3%) were achieved in both groups. No significant differences in BP outcomes between groups, however, were found. In conclusion, education by mail was an effective strategy for improving BP control and may be a viable approach for other immigrant groups if the education materials address their cultural needs.

    Invasive fungal diseases caused by yeasts still play an important role in the morbidity and mortality in neutropenic patients with haematological malignancies. Although the overall incidence of invasive candidiasis has decreased due to widespread use of antifungal prophylaxis, the incidence of non-Candida albicans Candida species is increasing compared with that of C.albicans, and mortality of invasive candidiasis continues to be high. In addition, there has been an increase in invasive infections caused by an array of uncommon yeasts, including species of the genus Malassezia, Rhodotorula, Trichosporon and Saprochaete, characterised by their resistance to echinocandins and poor prognosis.

    Purpose We evaluated the efficacy and toxicity of mammalian target rapamycin inhibitors in Korean patients with metastatic renal cell carcinoma (mRCC) with chronic renal insufficiency not requiring dialysis. Materials and Methods Korean patients with mRCC and chronic renal insufficiency not requiring dialysis treated with everolimus or temsirolimus between January 2008 and December 2014 were included. Patient characteristics, clinical outcomes, and toxicities were evaluated. Overall survival (OS) and progression-free survival (PFS) durations were evaluated according to the degree of renal impairment. Results Eighteen patients were considered eligible for the study (median age, 59 years). The median glomerular filtration rate was 51.5 mL/min/1.73 m2. The best response was partial response in six patients and stable disease in 11 patients. The median PFS and OS durations were 8 months (95% confidence interval [CI], 0 to 20.4) and 32 months (95% CI, 27.5 to 36.5), respectively. The most common non-hematologic and grade 3/4 adverse events included stomatitis, fatigue, flu-like symptoms, and anorexia as well as elevated creatinine level. Conclusion Mammalian target rapamycin inhibitors were efficacious and did not increase toxicity in Korean patients with mRCC and chronic renal insufficiency not requiring dialysis. PMID:26875195

    Background All over the world, chromosomal microarray (CMA) is now the first tier diagnostic assay for genetic testing to evaluate developmental delay (DD), mental retardation (MR), and autism spectrum disorder (ASD) with unknown etiology. The average diagnostic yield of the CMA test is known to be about 12.2%, while that of conventional G-banding karyotype is below 3%. This study aimed to assess the usefulness of CMA for the purpose of clinical diagnostic testing in the Korean population. Methods We performed CMA and multiplex ligation-dependent probe amplification (MLPA) tests in 96 patients with normal karyotype and unexplained DD, MR, or ASD. The CMA was conducted with CytoScan 750K array (Affymetrix, USA) with an average resolution of 100 kb. Results Pathogenic copy number variations (CNVs) were detected in 15 patients by CMA and in two patients by MLPA for four known microdeletion syndromes (Prader-Willi/Angelman syndrome, DiGeorge syndrome, Miller-Dieker syndrome and Williams syndrome) designated by National Health Insurance system in Korea. The diagnostic yield was 15.6% and 2.1%, respectively. Thirteen (13.5%) patients (excluding cases with pathogenic CNVs) had variants of uncertain clinical significance. There was one patient with a 17.1-megabase (Mb) region of homozygosity on chromosome 4q. Conclusions Our findings suggest the necessity of CMA as a routine diagnostic test for unexplained DD, MR, and ASD in Korea. PMID:26206688

    The purpose of this study is to examine the psychological states and the stress levels of the Korean mothers who have cleft lip and palate child patients. The authors explored whether psychological assessments of the mothers with child patients could play a role in screening for psychiatric counseling. Thirty-six mothers of child patients admitted to receive cleft lip and palate surgery at Seoul National University Children's Hospital were recruited as subjects of this study. The 3 questionnaires included in the study were the Beck Depression Inventory, Beck Anxiety Inventory, and Parenting Stress Inventory. We compared these results with those of general population according to the domestic studies. The statistical significances of these results were analyzed using Mann-Whitney method. The average score from the Beck Depression Inventory was 8.89 with standard deviation of 6.08. The average score from the Beck Anxiety Inventory was 9.69 with standard deviation of 6.89. In the Parenting Stress Inventory, the average score was 55.06 and standard deviation was 16.45. However, there were no statistically significant differences between mothers whose children have underwent surgery versus no surgery and mothers whose children had visible versus invisible anomalies. The reliable psychological analysis of depression, anxiety, and stress levels of the mothers of child patients allowed the authors to assess the psychological states of the mothers of child patients. Such assessment can play a vital role in the screening of candidates who need psychiatric treatment or consultation.

    Objectives HIV-infected patients are at increased risk of developing mental health symptoms, which negatively influence the treatment of the HIV-infection. Mental health problems in HIV-infected patients may affect public health. Psychopathology, including depression and substance abuse, can increase hazardous sexual behaviour and, with it, the chance of spreading HIV. Therefore, it is important to develop an optimal treatment plan for HIV-infected patients with mental health problems. The majority of HIV-infected patients in the Netherlands (almost 60%) are homosexual men. The main objectives of this study were to describe the clinical and demographic characteristics of patients with HIV who seek treatment for their mental health symptoms in the Netherlands. Secondly, we tested whether HIV infected and non-infected homosexual patients with a lifetime depressive disorder differed on several mental health symptoms. Methods We compared a cohort of 196 patients who visited the outpatient clinic for HIV and Mental Health with HIV-infected patients in the general population in Amsterdam (ATHENA-study) and with non-HIV infected mental health patients (NESDA-study). DSM-IV diagnoses were determined, and several self-report questionnaires were used to assess mental health symptoms. Results Depressive disorders were the most commonly occurring diagnoses in the cohort and frequent drug use was common. HIV-infected homosexual men with a depressive disorder showed no difference in depressive symptoms or sleep disturbance, compared with non-infected depressive men. However, HIV-positive patients did express more symptoms like fear, anger and guilt. Although they showed significantly more suicidal ideation, suicide attempts were not more prevalent among HIV-infected patients. Finally, the HIV-infected depressive patients displayed a considerably higher level of drug use than the HIV-negative group. Conclusion Habitual drug use is a risk factor for spreading HIV. It is also more

    Purpose Several studies have shown that HIV patients are at higher risk of lung cancer. Our aim is to analyse the prevalence and features of lung cancer in HIV-infected patients. Methods The clinical charts of 4,721 HIV-infected patients seen in three hospitals of southeast Spain (study period 1992–2012) were reviewed, and all patients with a lung cancer were analysed. Results There were 61 lung cancers, giving a prevalence of 1.2%. There was a predominance of men (82.0%), and smokers (96.6%; mean pack-years 35.2), with a median age of 48.0 (41.7–52.9) years, and their distribution according to risk group for HIV was: intravenous drug use 58.3%, homosexual 20.0%, and heterosexual 16.7%. Thirty-four (56.7%) patients were Aids cases, and 29 (47.5%) had prior pulmonar events: tuberculosis 16, bacterial pneumonia 9, and P. jiroveci pneumonia 4. The median nadir CD4 count was 149/mm3 (42–232), the median CD4 count at the time of diagnosis of the lung cancer was 237/mm3 (85–397), and 66.1%<350/mm3. 66.7% were on ART, and 70% of them had undetectable HIV viral load. The most common histological types of lung cancer were adenocarcinoma and epidermoid, with 24 (40.0%) and 23 (38.3%) cases, respectively. There were 49 (80.3%) cases with advanced stages (III and IV) at diagnosis. The distribution of treatments was: only palliative 23 (39.7%), chemotherapy 14 (24.1%), surgery and chemotherapy 8 (13.8%), radiotherapy 7 (12.1%), surgery 4 (6.9%), and other combined treatments 2 (3.4%). Forty-six (76.7%) patients died, with a median survival time of 3 months. The Kaplan-Meier survival rate at 6 months was 42.7% (at 12 months 28.5%). Conclusions The prevalence of lung cancer in this cohort of HIV-patients is high. People affected are mainly men, smokers, with transmission of HIV by intravenous drug use, and around half of them with prior opportunistic pulmonary events. Most patients had low nadir CD4 count, and were immunosuppressed at the time of diagnosis. Adenocarcinoma

    Serratia marcescens is a Gram-negative bacillus belonging to the Enterobacteriaceae family. Because of increasing reports of antimicrobial resistance, this bacterium has received considerable attention and has emerged as an important pathogen. In order to reveal clinical and microbiological characteristics of S. marcescens cutaneous infection and to suggest appropriate antibiotic treatment, we retrospectively analyzed 17 strains isolated from wound swabs of Korean patients between November 2005 and March 2014. A total of 13 patients (five men and eight women) were included in our study, with a mean age of 46.3 years (range, 21-82). Based on medical history, seven patients were classified as immunocompromised. Prior predisposing factors for infections were noted in 12 patients, including pre-existing leg ulcers or dermatitis (5/13), preceding cancer surgeries (2/13), plastic surgeries and filler injection (2/13), traumas (2/13) and medical procedures following cutaneous abscess (1/13). Cutaneous infections showed various clinical presentations, including spontaneous dermal abscess, fingernail change, painful nodules and papular erosions. We found that third- and fourth-generation cephalosporins, gentamicin, levofloxacin and meropenem appeared active against all 17 strains in vitro. Clinically, all patients treated with empirical first-generation cephalosporin showed treatment resistance, and oral quinolone monotherapy was the most preferred antibiotic regimen without treatment failure, with an average treatment duration of 25 days (range, 14-42). This study demonstrates the various clinical presentations and treatment responses for cutaneous S. marcescens infection. Moreover, we suggest that initial antibiotic coverage should be broad enough to account for multidrug resistance in this rare pathogen.

    2009-01-01

    Nearly one fourth of individuals with human immunodeficiency virus (HIV) infection have hepatitis C virus (HCV) infection in the US and Western Europe. With the availability of highly active antiretroviral therapy and the consequent reduction in opportunistic infections, resulting in the prolongation of the life span of HIV-infected patients, HCV co-infection has emerged as a significant factor influencing the survival of HIV patients. Patients with HIV/HCV co-infection have a faster rate of fibrosis progression resulting in more frequent occurrences of cirrhosis, end-stage liver disease, and hepatocellular carcinoma. However, the mechanism of interaction between the two viruses is not completely understood. The treatment for HCV in co-infected patients is similar to that of HCV mono-infection; i.e., a combination of pegylated interferon and ribavirin. The presence of any barriers to anti-HCV therapy should be identified and eliminated in order to recruit all eligible patients. The response to treatment in co-infected patients is inferior compared to the response in patients with HCV mono-infection. The sustained virologic response rate is only 38% for genotype-1 and 75% for genotype-2 and -3 infections. Liver transplantation is no longer considered a contraindication for end-stage liver disease in co-infected patients. However, the 5 year survival rate is lower in co-infected patients compared to patients with HCV mono-infection (33% vs 72%, P = 0.07). A better understanding of liver disease in co-infected patients is needed to derive new strategies for improving outcome and survival. PMID:19673011

    We investigated the distribution of Malassezia yeast in 120 Chinese (20 patients from each of six cities) and 20 Korean patients with scalp seborrheic dermatitis (SD) and dandruff (SD/D) using ITS1 and ITS2 polymerase chain reaction-restriction fragment length polymorphism. Bioactivity was studied by quantifying sebum lipid production by human primary sebocytes and inflammatory cytokine, interleukin-8 (IL-8) production was studied by exposing HaCaT keratinocytes with extracts of five standard Malassezia strains; M. globosa, M. restricta, M. sympodialis, M. dermatis and M. slooffiae. M. restricta and M. globosa were the most frequently encountered species from both Chinese and Korean patients. These two Malassezia species also promoted neutral lipid synthesis although the result was not statistically significant and induced significant increase in IL-8 production among the five Malassezia species studied. The study suggests a possible role of these organisms in the pathogenesis of SD/D. PMID:26786542

    Background and Purpose Variant alleles of CYP2C9 and VKORC1 account for differences in anticoagulation response. We sought to establish a warfarin dosing formula for individualized target International Normalization Ratio of Prothrombin Times (INRs) using data from single nucleotide polymorphisms (SNPs) in VKORC1 and CYP2C9 in Korean patients. Methods Ischemic stroke patients displaying stable target INR for at least 3 months before enrollment were analyzed. Warfarin and vitamin K levels were measured to adjust for confounders. Phenotypes were defined using the 'warfarin response index' (WRI) defined as INR divided by the daily maintenance warfarin dose. We tested SNPs in CYP2C9 (3 sites: 430C>T (rs1799853), 1075A>C (rs1057910), 1076T>C) and VKORC1 (14 sites: 381C>T, 861C>A (rs17880887), 2653G>C, 3673A>G, 5496G>T, 5808T>G (r17882154), 6009C>T, 6484T>C (rs9934438), 6853C>T (rs17886369), 7566T>C, 8767G>C, 8814T>C, 9041G>A (rs17880624), and 9071G>T) using a standard sequencing method. Multivariate linear regression analysis was applied to establish the formula for warfarin dosage. Results All 204 patients had excellent drug compliance. The mean INR was 2.22 (+0.56) and mean daily maintenance dose of warfarin was 3.92 mg (+1.54). Patients with low WRI were younger (P<0.001) with high body mass index (P=0.003), high prevalence of wild-type CYP2C9 polymorphism (1075A>C, P<0.001), and six heterozygote SNPs in VRORC1 (P<0.001), which were tightly interlinked (381T>C, 3673G>A, 6484T>C, 6853C>G. 7566C>T, 9041G>A) (r2=1). Based on these data, a warfarin dosing formula was established. Conclusions WRI is influenced by age, body mass index and SNPs in VKORC1 and CYP2C9 in Korean stroke patients. The obtained warfarin dosing formula may be clinically applicable. PMID:24324947

    BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) infection is emerging as a major problem in vascular surgical practice. The aim of this study was to review the management of patients with MRSA infection complicating vascular surgical operations. METHODS: Data were obtained from the vascular audit, case notes, intensive therapy unit (ITU) notes, high dependency unit (HDU) notes and microbiological records of patients who underwent either arterial reconstruction (n = 464) or limb amputation (n = 110) between April 1994 and October 1998. RESULTS: Forty-nine vascular surgical patients developed clinical MRSA infection (9%). Clinical MRSA infection in patients who had undergone aorto-iliac reconstruction (n = 18) was associated with a 56% mortality (n = 10) and the most common infections were bacteraemia (55%) and pneumonia (50%). MRSA infection occurred in 17 patients who had undergone infra-inguinal bypass and was associated with a 29% mortality (n = 5). The most common site of MRSA infection was the groin wound (76%) leading to anastomotic dehiscence and death in one patient (11%) and necessitating wound debridement in 4 patients (22%). MRSA infection of the groin wound in the presence of a prosthetic graft (n = 3) led to anastomotic dehiscence in 2 patients, and graft excision in 2 patients. Similar complications were not observed in the presence of an underlying autogeneous long saphenous vein graft (n = 16). MRSA infection following major lower limb amputation (n = 14) was associated with death in 5 patients (36%). Wound infection in 10 amputees (71%) led to revision of the amputation to a higher level in 2 (14%) and wound debridement in 2 (14%). CONCLUSIONS: MRSA infection has a high mortality in vascular surgical patients in general, and following aorto-iliac reconstruction in particular. Autogeneous vein may confer some protection against local complications following groin wound infection. Strategies aimed at reducing the incidence of infection

  18. The Level of Serum Cholesterol is Negatively Associated with Lean Body Mass in Korean non-Diabetic Cancer Patients

    PubMed Central

    2016-01-01

    Due to poor nutrition and abnormal energy metabolism, cancer patients typically experience the loss of muscle mass. Although the diabetic conditions or dyslipidemia have been reported as a causal link of cancer but the consequence of such conditions in relation to gain or loss of skeletal muscle mass in cancer patients has not been well documented. The purpose of this study was to investigate the relationship of lean body mass and systemic parameters related to lipid metabolism in non-diabetic cancer patients using data from the Korean National Health and Nutrition Examination Survey (KNHANES) 2008-2011. As results the level of serum total cholesterol (total-C) was negatively associated with both total lean body mass and appendicular lean body mass in cancer patients after adjustment for sex, physical activity, energy intake and comorbidity. The associations between consumption of dietary factors (energy, carbohydrate, protein and fat) and lean body mass were disappeared after adjusting comorbidities of cancer patients. Multivariate-adjusted linear regression analysis by quartiles of serum total-C showed that higher quartile group of total-C had significantly lower percent of lean body mass than reference group in cancer patients. The data indicate that serum lipid status can be the potential estimate of loss of skeletal muscle mass in cancer patients and be referenced in nutrition care of cancer patients under the onset of cachexia or parenteral/enteral nutrition. This data need to be confirmed with large pool of subjects and should be specified by stage of cancer or the site of cancer in future studies. PMID:27152302

    Due to poor nutrition and abnormal energy metabolism, cancer patients typically experience the loss of muscle mass. Although the diabetic conditions or dyslipidemia have been reported as a causal link of cancer but the consequence of such conditions in relation to gain or loss of skeletal muscle mass in cancer patients has not been well documented. The purpose of this study was to investigate the relationship of lean body mass and systemic parameters related to lipid metabolism in non-diabetic cancer patients using data from the Korean National Health and Nutrition Examination Survey (KNHANES) 2008-2011. As results the level of serum total cholesterol (total-C) was negatively associated with both total lean body mass and appendicular lean body mass in cancer patients after adjustment for sex, physical activity, energy intake and comorbidity. The associations between consumption of dietary factors (energy, carbohydrate, protein and fat) and lean body mass were disappeared after adjusting comorbidities of cancer patients. Multivariate-adjusted linear regression analysis by quartiles of serum total-C showed that higher quartile group of total-C had significantly lower percent of lean body mass than reference group in cancer patients. The data indicate that serum lipid status can be the potential estimate of loss of skeletal muscle mass in cancer patients and be referenced in nutrition care of cancer patients under the onset of cachexia or parenteral/enteral nutrition. This data need to be confirmed with large pool of subjects and should be specified by stage of cancer or the site of cancer in future studies. PMID:27152302

    Purpose To evaluate the diagnostic value of the Korean version of the Douleur Neuropathique 4 (DN4) questionnaire and to validate this questionnaire in terms of psychometric properties in patients with chronic pain due to degenerative spinal disease. Materials and Methods The Korean version of the DN4 questionnaire, which was translated and linguistically validated by the MAPI Research Group, was tested on 83 patients with lumbar or lumbar-radicular pain. Test-retest reliability was evaluated in a subsample of 40 patients who completed two assessments with an interval of 2 weeks. Nociceptive pain and neuropathic component pain were diagnosed in 40 and 43 patients, respectively. Results The Cronbach's α coefficient of internal consistency was 0.819, and the test-retest intraclass correlation coefficient (3, 1) (95% confidence interval) was 0.813 (0.776–0.847) (n=40). The area under the receiver-operator characteristics curve was 0.953 (p<0.001), with 95% confidence interval between 0.869 and 0.990. The Korean version of the DN4 questionnaire showed a sensitivity of 100% and 87.1%, and a specificity of 88.2% and 94.1% at the cutoff value of 3/10 and 4/10, respectively, for discriminating neuropathic component pain. Conclusion The present study demonstrated the good discriminatory power of DN4 between nociceptive pain and neuropathic component pain in patients with lumbar or lumbar-radicular pain. PMID:26847299

    The objectives of this review were (1) to review recent literature on the rates, risk factors, and outcomes of infections in patients who had chronic kidney disease (CKD) and did or did not require renal replacement therapy; (2) to review literature on the efficacy and use of selected vaccines for patients with CKD; and (3) to outline a research framework for examining key issues regarding infections in patients with CKD. Infection-related hospitalizations contribute substantially to excess morbidity and mortality in patients with ESRD, and infection is the second leading cause of death in this population. Patients who have CKD and do not require renal replacement therapy seem to be at higher risk for infection compared with patients without CKD; however, data about patients who have CKD and do not require dialysis therapy are very limited. Numerous factors potentially predispose patients with CKD to infection: advanced age, presence of coexisting illnesses, vaccine hyporesponsiveness, immunosuppressive therapy, uremia, dialysis access, and the dialysis procedure. Targeted vaccination seems to have variable efficacy in the setting of CKD and is generally underused in this population. In conclusion, infection is a primary issue when caring for patients who receive maintenance dialysis. Very limited data exist about the rates, risk factors, and outcomes of infection in patients who have CKD and do not require dialysis. Future research is needed to delineate accurately the epidemiology of infections in these populations and to develop effective preventive strategies across the spectrum of CKD severity.

    Brachydactyly type C (BDC) is characterized by shortening of the middle phalanges of the index, middle, and little fingers. Hyperphalangy of the index and middle finger and shortening of the first metacarpal can also be observed. BDC is a rare genetic condition associated with the GDF5 gene, and this condition has not been confirmed by genetic analysis so far in the Korean population. Herein, we present a case of a 6-yr-old girl diagnosed with BDC confirmed by molecular genetic analysis. The patient presented with shortening of the second and third digits of both hands. Sequence analysis of the GDF5 gene was performed and the pathogenic mutation, c.1312C>T (p.Arg438Cys), was identified. Interestingly, this mutation was previously described in a patient who presented with the absence of the middle phalanges in the second through fifth toes. However, our patient showed no involvement of the feet. Considering intrafamilial and interfamilial variability, molecular analysis of isolated brachydactyly is warranted to elucidate the genetic origin and establish a diagnosis.

    Objective Clozapine is the treatment of choice for refractory schizophrenia. The aim of this study was to compare the pharmacokinetics of the brand name (Clozaril) formulation and a generic formulation (Clzapine) of clozapine in Korean schizophrenic patients. Methods A prospective, randomized, crossover study was conducted to evaluate the steady-state pharmacokinetic profiles of Clozaril and Clzapine. Schizophrenic patients were randomized to receive either the brand name or generic formulation (100 mg twice daily) for 10 days, followed by the other formulation for 10 days. Plasma samples were collected on the last day of each treatment period. Results Twenty-two of 28 patients (78.6%) completed the study. The mean Cmax,ss values for Clzapine and Clozaril were 524.62 and 551.18 ng/mL, and the mean AUC0-12 values were 4479.90 hr·ng/mL and 4724.56 hr·ng/mL, respectively. The 90% CI values for the natural logarithmically transformed Cmax,ss and AUC0-12 ratios (Clzapine to Clozaril) after a single oral dose (100 mg) were 0.934 (0.849-1.028) and 0.936 (0.869-1.008), respectively. Five patients (20.8%) among 24 patients who took Clzapine reported 11 adverse events and six adverse events were reported by four patients (15.4%) among 26 who took Clozaril; there were no significant differences on physical examination or in vital signs, ECG, and laboratory tests between groups. Conclusion Generic clozapine (Clzapine) appears to be bioequivalent to brand name clozapine (Clozaril). PMID:26207129

    The aim of this study was to describe cutaneous infections, which are zosteriform in distribution, including two patients with dermatomal Staphylococcus aureus infection. Herpes zoster infectious lesions usually occur in a dermatomal distribution. Other viruses, such as herpes simplex virus, can also appear with zosteriform lesions and closely mimic the clinical presentation of herpes zoster. Additionally, other skin infections, less commonly, are zosteriform. Two patients who developed zosteriform S aureus skin infection are described. A medical literature search for zosteriform dermatomal infections yielded other cutaneous infections with a zosteriform presentation. Two patients had S aureus and methicillin-resistant S aureus infection with skin lesions occupying the T11-T12 dermatomes and the T4 dermatome, respectively. They responded to antibacterial agents and adjuvant therapy. Patients with viral, fungal, and spirochete zosteriform infections are summarized. In addition to varicella-zoster virus infection, zosteriform skin infection can occur with viral (varicella-zoster virus, herpes simplex virus, and Epstein-Barr virus), superficial (dermatophyte), and deep (phaeohyphomycosis and zygomycosis) fungal, and bacterial (S aureus and methicillin-resistant S aureus) infections. These infections should be considered in the differential diagnosis of a zosteriform infection that does not present with the classic clinical picture for herpes zoster or that does not respond to standard treatments for varicellazoster virus.

    We report a 52-yr-old Korean woman with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) whose diagnosis was confirmed by skin biopsy and the presence of a novel mutation in the NOTCH3 gene. The patient's clinical features were rather unusual in that 1) clinical presentations were only two episodes of stroke and mild dementia unaccompanied by mood disturbances or migraine, and 2) there was no family history. Brain MRI showed T2 hyperintensities in both temporal pole areas in line with the recent suggestion by O'Sullivan et al. that the abnormality could be a radiologic marker of CADASIL. FDG-PET also showed a hypometabolism in the temporal pole areas with an abnormal finding on MRI in addition to the hypometabolism in cortical and subcortical regions. We could learn from this case that CADASIL may be included in the differential diagnoses in patients with vascular dementia associated with a small vessel disease, even in the absence of a family history, especially when there are no known stroke risk factors and when the MRI shows T2 hyperintensity in the temporal pole regions.

    Objective Cognitive symptoms are an important component of depression and the Perceived Deficits Questionnaire-Depression is one of only a few instruments available for the subjective assessment of cognitive dysfunction in depression. Thus, the present study aimed to validate a Korean version of the PDQ-D (K-PDQ-D) using patients with major depressive disorder (MDD). Methods This study included 128 MDD patients who were assessed at study entry and 86 of these patients were then completed 12 weeks of antidepressant monotherapy. All subjects were assessed with the K-PDQ-D, the Montgomery-Asberg Depression Rating Scale (MADRS), the Sheehan Disability Scale (SDS), the EuroQol-5 dimensions questionnaire (EQ-5D), and the number of sick leave days taken in the previous week. The internal consistency, Guttman’s split-half and test-retest reliabilities, factorial analyses, and concurrent and predictive validities of the K-PDQ-D were investigated. Results The K-PDQ-D exhibited excellent internal consistency and reliabilities, and was composed of four factors with high coefficients of determination. The concurrent validity analyses revealed that the K-PDQ-D scores were significantly correlated with the MADRS, SDS, and EQ-5D scores and the number of sick leave days taken. The K-PDQ-D scores at study entry significantly predicted changes in sick leave days and EQ-5D score from study entry to the 12-week endpoint. Conclusion The newly developed K-PDQ-D is a reliable and valid instrument for the evaluation of subjective cognitive symptoms in MDD patients. The K-PDQ-D may assist in the gathering of unique information regarding subjective cognitive complaints, which is important for the comprehensive evaluation of patients with MDD. PMID:26792037

    Purpose. Patients may not achieve a clinical benefit after percutaneous cholecystostomy due to the inherent difficulty in identifying patients who truly have infected gallbladders. We attempted to identify imaging and biochemical parameters which would help to predict which patients have infected gallbladders. Methods. A retrospective review was performed of 52 patients undergoing percutaneous cholecystostomy for clinical suspicion of acute cholecystitis in whom bile culture results were available. Multiple imaging and biochemical variables were examined alone and in combination as predictors of infected bile, using logistic regression. Results. Of the 52 patients, 25 (48%) had infected bile. Organisms cultured included Enterococcus, Enterobacter, Klebsiella, Pseudomonas, E. coli, Citrobacter and Candida. No biochemical parameters were significantly predictive of infected bile; white blood cell count >15,000 was weakly associated with greater odds of infected bile (odds ratio 2.0, p = NS). The presence of gallstones, sludge, gallbladder wall thickening and pericholecystic fluid by ultrasound or CT were not predictive of infected bile, alone or in combination, although a trend was observed among patients with CT findings of acute cholecystitis toward a higher 30-day mortality. Radionuclide scans were performed in 31% of patients; all were positive and 66% of these patients had infected bile. Since no patient who underwent a radionuclide scan had a negative study, this variable could not be entered into the regression model due to collinearity. Conclusion. No single CT or ultrasound imaging variable was predictive of infected bile, and only a weak association of white blood cell count with infected bile was seen. No other biochemical parameters had any association with infected bile. The ability of radionuclide scanning to predict infected bile was higher than that of ultrasound or CT. This study illustrates the continued challenge to identify bacterial cholecystitis

    2016-01-01

    Purpose The goal of this study was to develop a Korean version of the Benefit, Satisfaction, and Willingness to Continue (BSW) questionnaire from the original version, with subsequent linguistic validation by Korean patients with overactive bladder who undergo active treatment by a physician. Methods Translation and linguistic validation were performed in January 2013. The validation process included permission for translation, forward translation, reconciliation, backward translation, cognitive debriefing, and proofreading. Results During the forward translation process, the terms or phrases of ‘benefit,’ ‘willingness,’ “have you had any benefit?,” “taking all things into account” were adjusted to be more appropriate expressions in the Korean language than those used in the original version. During the backward translation process, no changes were made in terms of the sematic equivalence. In the cognitive debriefing session, 5 patients were asked to fill in the answers within 5 minutes; most reported that the translated questions were clear and easy to understand. One patient felt the questions were a little bit difficult to understand; however, the panel decided not to change the expressions because the overall level of comprehension was high and the translated terms were accurate enough to convey the meaning of the original version of the BSW. Conclusions The present study showed a successful linguistic validation of the BSW questionnaire. Further studies are needed to assess of the psychometric properties of the BSW. PMID:27706015

    Purpose Primary congenital glaucoma (PCG) is an autosomal recessive form of glaucoma that manifests within the first year of life and if left untreated, leads to irreversible blindness. Cytochrome P450 1B1 (CYP1B1) is the major gene known to be associated with PCG. The role of the CYP1B1 gene in disease pathogenesis and the relatively low detection rate of CYP1B1 mutations in some populations, especially Asians, remain unexplained. We hypothesized that altered gene dosage of CYP1B1 or anterior segmental dysgenesis causative genes may be involved in the pathogenesis of PCG. Methods We performed whole genome exon-focused array comparative genome hybridization (aCGH) to identify copy number variation (CNV) in 20 Korean PCG patients and their parents. Results We identified 12 patients with at least one rare gene-containing copy number variation each, corresponding to 25 CNVs (5 deletions and 20 duplications) at frequencies of 5-30% in PCG patients and 0% in controls. The 25 CNVs were not located at known chromosomal loci for PCG, namely GLC3A, which harbors CYP1B1 (2p21), GLC3B (1p36.2-p36.1), or GLC3C (14q23), and did not include any target genes associated with PCG or anterior segmental dysgenesis. Conclusions Further genetic studies with larger cohorts of patients are necessary to validate our results and to elucidate other genetic mechanisms underlying PCG, because the identified CNVs might be PCG-specific pathogenic variants and may explain the disease pathogenesis of PCG.

    A retrospective review of all 248 liver biopsies performed in patients with HIV infection at two referral centres in London over a 12 year period revealed five cases of major bleeding following biopsy, with four deaths. The risk of major bleeding was 2.0%, and mortality was 1.6% following liver biopsy. The risk of bleeding as much higher than in published series of biopsies done in patients without HIV infection, owing in part to the high prevalence of thrombocytopaenia and clotting abnormalities in patients with HIV infection. HIV infection per se may also increase the risk of bleeding following liver biopsy. PMID:8655172

    The authors have reviewed the clinical manifestations and therapy of hydrocephalus shunt infections in 32 patients with a total of 35 shunt infections. These 35 infections accounted for 43 hospital admissions. First infections usually developed within 2 months following surgery. At the time of diagnosis, 89% of patients were febrile. Fever and cough as a symptom complex characterized the initial clinical presentation in six of 19 episodes of infection complicating ventriculoatrial (VA) shunts, as compared with none of 21 episodes in which infection complicated ventriculoperitoneal (VP) shunts. Seven of 21 infectious episodes occurring in patients with VP shunts in situ were associated with significant abdominal pain and tenderness. These patients usually had no other clinical features to suggest shunt infection. Both of these symptom complexes often led to delays in diagnosis and treatment. Causative organisms included Staphylococcus epidermidis in 21, Staphylococcus aureus in seven, Gram-negative aerobic bacilli in seven, diphtheroids in five, Streptococcus species in four, and anaerobes in three. Five infections were polymicrobial in nature. Positive blood cultures were seen in 13 of 17 infectious episodes complicating VA shunts, as compared with only three of 13 other infections. When the shunt was completely removed, with or without replacement, all 13 patients were cured. When intravenous antibiotics were administered in conjunction with incomplete shunt removal, only eight of 15 courses resulted in cure. Intraventricular antibiotics were administered in four patients and all were cured. Therapy of shunt infections with parenteral antibiotics and incomplete shunt removal is associated with an unacceptably high failure rate.

    Despite the huge advance that antiretroviral therapy represents for the prognosis of infection by the human immunodeficiency virus (HIV), opportunistic infections (OIs) continue to be a cause of morbidity and mortality in HIV-infected patients. OIs often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an OI. The present article updates our previous guidelines on the prevention and treatment of various OIs in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome. PMID:26976381

    Tuberculosis is the most common opportunistic infection in human immunodeficiency virus (HIV) infected persons. HIV-infected patients have a high incidence of tuberculous meningitis as well. The exact incidence and prevalence of tuberculous meningitis in HIV-infected patients are not known. HIV infection does not significantly alter the clinical manifestations, laboratory, radiographic findings, or the response to therapy. Still, some differences have been noted. For example, the histopathological examination of exudates in HIV-infected patients shows fewer lymphocytes, epithelioid cells, and Langhan's type of giant cells. Larger numbers of acid-fast bacilli may be seen in the cerebral parenchyma and meninges. The chest radiograph is abnormal in up to 46% of patients with tuberculous meningitis. Tuberculous meningitis is likely to present with cerebral infarcts and mass lesions. Cryptococcal meningitis is important in differential diagnosis. The recommended duration of treatment in HIV-infected patients is 9-12 months. The benefit of adjunctive corticosteroids is uncertain. Antiretroviral therapy and antituberculosis treatment should be initiated at the same time, regardless of CD4 cell counts. Tuberculous meningitis may be a manifestation of paradoxical tuberculosis-associated immune reconstitution inflammatory syndrome. Some studies have demonstrated a significant impact of HIV co-infection on mortality from tuberculous meningitis. HIV-infected patients with multidrug-resistant tuberculous meningitis have significantly higher mortality. The best way to prevent HIV-associated tuberculous meningitis is to diagnose and isolate infectious cases of tuberculosis promptly and administer appropriate treatment.

    Background: We anticipated that patients with HIV infection living in endemic areas were at greater risk of infection which can reactivate due to immunosuppression; therefore, we analyzed the prevalence of latent Leishmania infantum infection in patients infected with HIV. Methods: A total of 179 patients with HIV infection were screened for the presence of anti-Leishmania antibodies using indirect immunofluorescent antibody test (IFAT) (Leishmania-spot IF; bioMérieux, Marcy l’Etoile, France). All patients were followed up for at least 1 year. The primary end-point was to confirm the presence of Leishmania infection. Results: Significant titer of antibodies to Leishmania was detected in six (3%; 95% confidence interval: 0.5–5.5%) asymptomatic patients. Two of them had visceral leishmaniasis that was confirmed by parasite visualization in clinical samples, the presence of Leishmania promastigotes in Novy–MacNeal–Nicolle culture, polymerase chain reaction (PCR)-based methods, and/or urinary antigen test. Among 173 patients with indirect immunofluorescent antibody test below 1∶40, one HIV-infected patient severely immunosuppressed, confirmed negative by IFAT, was diagnosed of visceral leishmaniasis. Conclusion: The use of indirect immunofluorescent antibody test for Leishmania screening is not justified in asymptomatic patients with HIV infection living in endemic areas due to the small rate of significant antibody titer and the low frequency of clinical disease.

    Geriatric assessment (GA) is resource-consuming, necessitating screening tools to select appropriate patients who need full GA. The objective of this study is to design a novel geriatric screening tool with easy-to-answer questions and high performance objectively selected from a large dataset to represent each domain of GA. A development cohort was constructed from 1284 patients who received GA from May 2004 to April 2007. Items representing each domain of functional status, cognitive function, nutritional status, and psychological status in GA were selected according to sensitivity (SE) and specificity (SP). Of the selected items, the final questions were chosen by a panel of oncologists and geriatricians to encompass most domains evenly and also by feasibility and use with cancer patients. The selected screening questions were validated in a separate cohort of 98 cancer patients. The novel screening tool, the Korean Cancer Study Group Geriatric Score (KG)-7, consisted of 7 items representing each domain of GA. KG-7 had a maximal area under the curve (AUC) of 0.93 (95% confidence interval (CI) 0.92-0.95) in the prediction of abnormal GA, which was higher than that of G-8 (0.87, 95% CI 0.85-0.89) within the development cohort. The cut-off value was decided at ≤ 5 points, with a SE of 95.0%, SP of 59.2%, positive predictive value (PPV) of 85.3%, and negative predictive value (NPV) of 82.6%. In the validation cohort, the AUC was 0.82 (95% CI 0.73-0.90), and the SE, SP, PPV, and NPV were 89.5%, 48.6%, 77.3%, and 75.0%, respectively. Furthermore, patients with higher KG-7 scores showed significantly longer overall survival (OS) in the development and validation cohorts. In conclusions, the KG-7 showed high SE and NPV to predict abnormal GA. The KG-7 also predicted OS. Given the results of our studies, the KG-7 could be used effectively in countries with high patient burden and low resources to select patients in need of full GA and intervention. PMID:26401951

    Geriatric assessment (GA) is resource-consuming, necessitating screening tools to select appropriate patients who need full GA. The objective of this study is to design a novel geriatric screening tool with easy-to-answer questions and high performance objectively selected from a large dataset to represent each domain of GA. A development cohort was constructed from 1284 patients who received GA from May 2004 to April 2007. Items representing each domain of functional status, cognitive function, nutritional status, and psychological status in GA were selected according to sensitivity (SE) and specificity (SP). Of the selected items, the final questions were chosen by a panel of oncologists and geriatricians to encompass most domains evenly and also by feasibility and use with cancer patients. The selected screening questions were validated in a separate cohort of 98 cancer patients. The novel screening tool, the Korean Cancer Study Group Geriatric Score (KG)-7, consisted of 7 items representing each domain of GA. KG-7 had a maximal area under the curve (AUC) of 0.93 (95% confidence interval (CI) 0.92−0.95) in the prediction of abnormal GA, which was higher than that of G-8 (0.87, 95% CI 0.85–0.89) within the development cohort. The cut-off value was decided at ≤ 5 points, with a SE of 95.0%, SP of 59.2%, positive predictive value (PPV) of 85.3%, and negative predictive value (NPV) of 82.6%.

    Hip joint replacement is 1 of the most successful surgical procedures of the last century and the number of replacements implanted is steadily growing. An infected hip arthroplasty is a disaster, it leads to patient suffering, surgeon's frustration and significant costs to the health system. The treatment of an infected hip replacement is challenging, healing rates can be low, functional results poor with decreased patient satisfaction. However, if a patient-adapted treatment of infected hip joints is used a success rate of above 90% can be obtained.Patient-adapted treatment is based on 5 important concepts: teamwork; understanding the biofilm; diagnostic accuracy; correct definition and classification of PJI; and patient-tailored treatment.This review presents a patient-adapted treatment strategy to prosthetic hip infection. It incorporates the best aspects of the single and staged surgical strategies and promotes the short interval philosophy for the 2-stage approach. PMID:26044528

    Two patients with known human immunodeficiency virus (HIV) infections and receiving antiretroviral treatment developed neuromyelitis optica (Devic's disease). One patient tested positive for serum aquaporin-4 immunoglobulin G antibodies. Both patients were treated with high dose pulsed intravenous methylprednisolone followed by standard sessions of plasma exchange both at the onset attack and during disease relapses. For maintenance therapy, one patient received rituximab infusions and the second patient received mycophenolate mofetil orally. Despite treatment, both patients are currently wheelchair-bound due to severe paraparesis. Neuromyelitis optica can occur in the course of HIV infection and poses an ongoing therapeutic challenge.

    In September 2011, the Korean Society of Hematology Lymphoma Working Party held a nationwide conference to establish a consensus for assessing bone marrow (BM) involvement in patients with lymphoma. At this conference, many clinicians, hematopathologists, and diagnostic hematologists discussed various topics for a uniform consensus in the evaluation process to determine whether the BM is involved. Now that the discussion has matured sufficiently to be published, we herein describe the consensus reached and limitations in current methods for assessing BM involvement in patients with lymphoma.

    Long-pulsed 755-nm alexandrite and long-pulsed 1064-nm neodymium:yttrium-aluminum-garnet (Nd:YAG) lasers have been used for photorejuvenation of the face. The aim of this study was to investigate the safety and efficacy of long-pulsed alexandrite and long-pulsed Nd:YAG lasers for photorejuvenation in Korea. One hundred and sixteen Korean patients with photo-aged facial skin were enrolled. Sixty-two patients with facial pigmentation underwent long-pulsed alexandrite laser treatment. Eleven patients that wanted to improve facial pigmentation with minimal pain had quasi-long-pulsed alexandrite laser treatment. Forty three patients had long-pulsed Nd:YAG laser therapy. Outcome assessments included standard photographs and global evaluation by blinded investigators. The self-assessment grade was provided in questionnaires. Forty-four percent of patients reported excellent or good improvement of their pigmentary lesions (>50% improvement) using a long-pulsed alexandrite laser. Of patients who underwent long-pulsed Nd:YAG laser treatment, 36% reported excellent or good improvement in skin tightening, 50% in facial flushing and 45% in pigmentary lesions. We conclude that long-pulsed alexandrite and long-pulsed Nd:YAG lasers are safe and effective for facial photorejuvenation in Koreans.

    The aim of this study was to compare anti-tumor necrosis factor-α (TNFα) treatment status in rheumatoid arthritis (RA) patients with the Korean National Health Insurance (KNHI) reimbursement eligibility criteria and with American College of Rheumatology (ACR) recommendations, Japan College of Rheumatology (JCR) guidelines and British Society for Rheumatology (BSR) guidelines. Between December 2011 and August 2012, outpatients from 17 South Korean general hospitals diagnosed with RA according to the 1987 ACR criteria were enrolled into a noninterventional, cross-sectional, observational study. Of 1700 patients (1414 female (83.2 %), mean age of 56.6 ± 12.0, mean disease duration 97.9 ± 91.8 months), 306 (18.0 %) had used anti-TNFα agents, and 224 (13.2 %) were currently using an anti-TNFα agent. Of 1394 anti-TNFα-naive patients, 32 (2.3 %) met KNHI reimbursement guidelines, 148 (10.6 %) met ACR recommendations, and 127 (9.1 %) and 126 (9.0 %) were considered eligible for anti-TNFα agents according to JCR and BSR guidelines, respectively. The main discrepancy was the higher active joint count required by the KNHI eligibility criteria. In the opinion of treating rheumatologists, the KNHI reimbursement criteria ineligibility accounted for 15.3 % (n = 213) of the reasons for not initiating anti-TNFα agents in anti-TNFα-naive group. The anti-TNFα user group showed significantly higher disease activity than the anti-TNFα-naive group based on DAS28 score. In comparison with the ACR recommendations and JCR and BSR guidelines, fewer patients met KNHI reimbursement eligibility criteria for anti-TNFα agents. The current amendment of the KNHI criteria based on DAS28 score will improve an access to biologic agents including anti-TNFα treatment for South Korean patients with active RA.

    Ehlers-Danlos syndrome (EDS) is a hereditary disorder of the connective tissue. EDS type IV (EDS IV), the vascular type of the disease, is characterized by easy bruising, thin skin with visible veins, and spontaneous rupture of the large arteries, uterus, or bowel. EDS IV is caused by mutations in the gene for type III procollagen (COL3A1). However, recent studies suggest that the causative mutation of EDS IV is not homogeneous. We report our experience with three patients presenting with clinical features of type IV EDS. A 48-yr-old woman presented with acute aortic dissection (patient 1) and 36-yr-old and 21-yr-old women presented with carotid-cavernous fistula (patients 2 and 3, respectively). All three patients bruised easily. Two patients (patients 1 and 3) had thin transparent skin with visible veins. Genetic analysis of COL3A1 revealed a Gly732Val (c.2195G>T) mutation in patient 1 and a duplication of 15 base pairs (c.3221_3235dup) which resulted in an interposition of five amino acids (p.Gly1074_Pro1078dup) in patient 2. However, no mutations were observed in COL3A1 or transforming growth factor β receptors 1 and 2 in patients 3, which might be either due to a deletion of single or multiple exons in the COL3A1 gene or due to a genetic heterogeneity. This is the first report of genetically confirmed cases of EDS IV in Korea. PMID:17728513

    We aimed; 1) to determine the validity of the EuroQol 5D (EQ-5D) for the health-related quality of life (HRQOL) of Korean patients with type 2 diabetes, and 2) to identify associated factors of the HRQOL of these patients. Follow-up surveys were conducted for consecutive patients with type 2 diabetes. HRQOL was assessed using the EQ-5D and the Short Form-36 (SF-36). The validity of EQ-5D was assessed with the perspectives of known group, convergent and discriminant validity. Additionally, a linear mixed model using a backward elimination was used for identify associated factors. Of the 1,072 patients included in the first survey, 858 (80.0%) completed the questionnaires in the follow-up. In the known group validity, the problem rates in each EQ-5D dimension were highest among women, elderly people, and less-educated subjects. The Spearman's ρ between the EQ-5D and the SF-36 scales were larger in the comparable dimensions than those in the less comparable dimensions. In the final model, we found that sex, age, education, body mass index, atrial fibrillation, stroke, and retinopathy were statistically significant. Our data suggest that the EQ-5D is a valid tool for Korean patients with type 2 diabetes and that various factors could affect their HRQOL. PMID:22379335

    The advent of combination antiretroviral drug regimens has transformed HIV infection from a fatal illness into a manageable chronic condition. All patients with HIV infection should be considered for antiretroviral therapy, regardless of CD4 count or HIV viral load, for individual benefit and to prevent HIV transmission. Antiretroviral drugs affect HIV in several ways: entry inhibitors block HIV entry into CD4 T cells; nucleotide and nucleoside reverse transcriptase inhibitors prevent reverse transcription from RNA to DNA via chain-terminating proteins; nonnucleoside reverse transcriptase inhibitors prevent reverse transcription through enzymatic inhibition; integrase strand transfer inhibitors block integration of viral DNA into cellular DNA; protease inhibitors block maturation and production of the virus. Current guidelines recommend six combination regimens for initial therapy. Five are based on tenofovir and emtricitabine; the other uses abacavir and lamivudine. Five include integrase strand transfer inhibitors. HIV specialists should assist with treating patients with complicated HIV infection, including patients with treatment-resistant HIV infection, coinfection with hepatitis B or C virus, pregnancy, childhood infections, severe opportunistic infections, complex drug interactions, significant drug toxicity, or comorbidities. Family physicians can treat most patients with HIV infection effectively by choosing appropriate treatment regimens, monitoring patients closely, and retaining patients in care. PMID:27092564

    Intermittent Pneumatic Compression (IPC) device has been used to prevent venous thromboembolism (VTE). This study investigated the effectiveness of IPC device. We evaluated incidences of deep vein thrombosis (DVT) and pulmonary embolism (PE) in total hip arthroplasty (THA) patients after use of IPC device, and compared with historical incidences from our institution. We applied IPC device in 741 patients who underwent 870 elective primary THAs from January 2010 to December 2013, DVT was detected in 3 patients (0.3%) by sonography, and one (0.1%) of them was symptomatic. Symptomatic PE occurred in 1 patient (0.1%) and there were no cases of fatal PE. The incidence of symptomatic DVT was significantly lower than the historical control (P = 0.042). The IPC is a safe and effective prophylaxis of VTE after primary THA in Korea. PMID:27478345

    Vitamins are essential micronutrients for maintenance of tissue functions. Vitamin deficiency is one of the most serious and common health problems among both chronic alcoholics and the homeless. However, the vitamin-level statuses of such people have been little studied. We evaluated the actual vitamin statuses of alcoholic homeless patients who visited an emergency department (ED). In this study the blood levels of vitamins B1, B12, B6, and C of 217 alcoholic homeless patients were evaluated retrospectively in a single urban teaching hospital ED. Vitamin C deficiency was observed in 84.3% of the patients. The vitamin B1, B12, and B6 deficiency rates, meanwhile, were 2.3%, 2.3%, and 23.5%, respectively. Comparing the admitted patients with those who were discharged, only the vitamin C level was lower. (P=0.003) In fact, the patients' vitamin C levels were markedly diminished, vitamin C replacement therapy for homeless patients should be considered in EDs.

    Pneumocystis jiroveci (formerly P. carinii) is an opportunistic fungus responsible for pneumonia in immunocompromised patients. Pneumocystosis in non-HIV-infected patients differs from AIDS-associated pneumocystosis in mostly two aspects: diagnosis is more difficult, and prognosis is worse. Hence, efforts should be made to target immunocompromised patients at higher risk of pneumocystosis, so that they are prescribed long-term, low-dose, trimethoprime-sulfamethoxazole, highly effective for pneumocystosis prophylaxis. Patients at highest risk include those with medium and small vessels vasculitis, lymphoproliferative B disorders (chronic or acute lymphocytic leukaemia, non-Hodgkin lymphoma), and solid cancer on long-term corticosteroids. Conversely, widespread use of prophylaxis in all patients carrier of inflammatory diseases on long-term corticosteroids is not warranted. The management of pneumocystosis in non-AIDS immunocompromised patients follows the rules established for AIDS patients. The diagnosis relies on the detection of P. jiroveci cyst on respiratory samples, while PCR does not reliably discriminate infection from colonization, in 2015. High-doses trimethoprim-sulfamethoxazole is, by far, the treatment of choice. The benefit of adjuvant corticosteroid therapy for hypoxic patients, well documented in AIDS patients, has a much lower level of evidence in non-HIV-infected patients, most of them being already on corticosteroid by the time of pneumocystosis diagnosis anyway. However, based on its striking impact on morbi-mortality in AIDS patients, adjuvant corticosteroid is recommended in hypoxic, non-HIV-infected patients with pneumocystosis by many experts and scientific societies.

    Background Although rosacea is a chronic cutaneous inflammatory disorder that's commonly seen in adults, the etiology and pathogenesis of the illness remain unclear. A well established diagnostic classification and grading system may play a critical role in performing research and it would serve as a diagnostic reference in the clinical field. Objective We sought to classify the patients with the new standard classification and grading system and we wanted determine the peculiar features and relationships of each subtype. We also analyzed the relationships between the degree of sun exposure and each subtype. Methods We reviewed the medical records and clinical photos of 168 patients who were diagnosed with rosacea from 2002 to 2007 at our hospital. The standard classification and grading system suggested by the National Rosacea Society (NRS) Expert Committee was adopted to evaluate each patient's subtype and the severity. Results The male:female ratio was 1:2.29. The mean age at the time of diagnosis was 47.8 years. The mean duration of disease was 3.5 years. Sun exposure and hot baths/exercise were the two most common precipitating factors, while the majority of patients did not have any specific factor that relieved their symptoms. According to the NRS classification and grading system, the patients were classified into four subtypes. One hundred sixty two (96.4%) patients were diagnosed with the erythematotelangiectatic subtype irrespective of severity. Eighty five (50.6%) patients had the papulopustular subtype and 24 (14.3%) patients had ocular rosacea. Eight (4.8%) patients displayed mild phymatous change. The degree of sun exposure had significant correlation with the development and severity of the erythematotelangiectatic subtype (p<0.05), while it had no correlation with the papulopustular, ocular and phymatous subtypes. Conclusion Although the erythematotelangiectatic subtype was the most common subtype of rosacea, many patients also had other subtypes

    Purpose Previous studies suggest that the concentration of 25-hydroxyvitamin D [25(OH)D] in cord blood may show an inverse association with respiratory tract infections (RTI) during childhood. The aim of the present study was to examine the influence of 25(OH)D concentrations in cord blood on infant RTI in a Korean birth cohort. Methods The levels of 25(OH)D in cord blood obtained from 525 Korean newborns in the prospective COhort for Childhood Origin of Asthma and allergic diseases were examined. The primary outcome variable of interest was the prevalence of RTI at 6-month follow-up, as diagnosed by pediatricians and pediatric allergy and pulmonology specialists. RTI included acute nasopharyngitis, rhinosinusitis, otitis media, croup, tracheobronchitis, bronchiolitis, and pneumonia. Results The median concentration of 25(OH)D in cord blood was 32.0 nmol/L (interquartile range, 21.4 to 53.2). One hundred and eighty neonates (34.3%) showed 25(OH)D concentrations less than 25.0 nmol/L, 292 (55.6%) showed 25(OH)D concentrations of 25.0-74.9 nmol/L, and 53 (10.1%) showed concentrations of ≥75.0 nmol/L. Adjusting for the season of birth, multivitamin intake during pregnancy, and exposure to passive smoking during pregnancy, 25(OH)D concentrations showed an inverse association with the risk of acquiring acute nasopharyngitis by 6 months of age (P for trend=0.0004). Conclusion The results show that 89.9% of healthy newborns in Korea are born with vitamin D insufficiency or deficiency (55.6% and 34.3%, respectively). Cord blood vitamin D insufficiency or deficiency in healthy neonates is associated with an increased risk of acute nasopharyngitis by 6 months of age. More time spent outdoors and more intensified vitamin D supplementation for pregnant women may be needed to prevent the onset of acute nasopharyngitis in infants. PMID:24244212

    Occult hepatitis C virus (HCV) infection is a new form of chronic HCV infection described by the presence of the genomic HCV-RNA in liver biopsy and/or peripheral blood mononuclear cell (PBMC) samples, and undetectable levels or absence of HCV-RNA and in the absence or presence of anti HCV antibodies in the plasma specimens. The aim of the present study was to evaluate the occurrence of occult HCV infection (OCI) among Iranian subjects infected with human immunodeficiency virus (HIV) using RT-nested PCR. From March 2014 until April 2015, 109 Iranian patients with established HIV infection were enrolled in this cross-sectional study. After extraction of viral RNA from the plasma and PBMC samples, HCV-RNA status was examined by RT-nested PCR using primers from the 5'-NTR. HCV genotyping was conducted using RFLP analysis. For the confirmation of HCV genotyping by RFLP method, the PCR products were sequenced. Of the 109 patients, 50 were positive for antibodies against HCV. The HCV-RNA was detected in PBMC specimens in 6 (10.2%) out of the total 59 patients negative for anti-HCV Abs and undetectable plasma HCV-RNA and also from 4 (8.0%) out of the total 50 patients positive for anti-HCV Abs and undetectable plasma HCV-RNA. HCV genotyping analysis showed that 6 (60.0%) patients were infected with HCV subtype 3a, 3 (30.0%) were infected with HCV subtype 1a and 1 (10.0%) patient was infected with HCV subtype 1b. This study revealed the incidence of OCI (9.2%) in HIV-infected Iranian patients. Hence, designing prospective studies focusing on the detection of OCI in these patients would provide more information. J. Med. Virol. 88:1960-1966, 2016. © 2016 Wiley Periodicals, Inc.

    We aimed to examine internalized stigma of patients with mental illness in Korea and identify the contributing factors to internalized stigma among socio-demographic, clinical, and psychosocial variables using a cross-sectional study design. A total of 160 patients were recruited from a university mental hospital. We collected socio-demographic data, clinical variables and administered self-report scales to measure internalized stigma and levels of self-esteem, hopelessness, social support, and social conflict. Internalized stigma was identified in 8.1% of patients in our sample. High internalized stigma was independently predicted by low self-esteem, high hopelessness, and high social conflict among the psychosocial variables. Our finding suggests that simple psychoeducation only for insight gaining cannot improve internalized stigma. To manage internalized stigma in mentally ill patients, it is needed to promote hope and self-esteem. We also suggest that a relevant psychosocial intervention, such as developing coping skills for social conflict with family, can help patients overcome their internalized stigma.

    Histoplasmosis is a systemic infection caused by the dimorphic fungus Histoplasma capsulatum. In immunocompromised patients, primary pulmonary infection can spread to the skin and meninges. Clinical manifestations appear in patients with a CD4(+) lymphocyte count of less than 150 cells/μL. Coccidioidomycosis is a systemic mycosis caused by Coccidioides immitis and Coccidioides posadasii. It can present as diffuse pulmonary disease or as a disseminated form primarily affecting the central nervous system, the bones, and the skin. Cryptococcosis is caused by Cryptococcus neoformans (var. neoformans and var. grubii) and Cryptococcus gattii, which are members of the Cryptococcus species complex and have 5 serotypes: A, B, C, D, and AD. It is a common opportunistic infection in patients with human immunodeficiency virus (HIV)/AIDS, even those receiving antiretroviral therapy. Histopathologic examination and culture of samples from any suspicious lesions are essential for the correct diagnosis of systemic fungal infections in patients with HIV/AIDS.

    PURPOSE The purpose of this study was to to analyze the effect of Type 2 diabetes on tooth mortality, implant treatment and prosthetic status. MATERIALS AND METHODS 275 Type 2 diabetics and 300 non-diabetics, aged 40-80 years were selected for analysis. The assessment of number of teeth, missing teeth, fixed prostheses (bridge pontics), implants using panoramic radiographs and dental records were carried out. RESULTS Diabetes mellitus (DM) patients had a higher number of missing teeth (P<.05) and placed implants (P=.074), age (P<.05), male gender percentage (P=.042), smoker percentage (P<.05) than non-DM patients. In univariate analysis, the patients in older group showed significantly higher number of tooth loss rate at the first dental examination than the patients in younger group. Tooth loss rate of smokers did not show higher value than that of non-smokers. When multiple variables including DM, age, smoking, gender were considered together, diabetics and older group patients showed significantly higher tooth loss rate at the first dental examination than non-diabetics and younger group patients, respectively. Smokers and male group did not show a significant difference than non-smokers and female group, respectively. CONCLUSION Tooth mortality and implant treatment rate were significantly higher in the DM group as indicated by univariate and multivariate logistic regression analysis. Old age groups showed significantly higher odds ratios and tooth loss rate. As diabetics showed the higher tooth loss rate than non-diabetics, diabetics also had more implant restorations than non-diabetics. PMID:23508020

    Lunula is the white, half-moon shaped area seen in proximal ends of some nails. Though a few studies have described the nail changes that can occur in association with HIV infection, none of these paid much attention to lunula. Aims and Objectives. To study the lunula in fingernails among HIV infected patients. Materials and Methods. An observational, cross-sectional study to record presence of lunula in 168 HIV-positive patients and compare it with age and sex matched 168 healthy HIV-negative control. Anolunula (absence of lunula) in HIV-positive patients was correlated with CD4 counts, stages of HIV infection, time since patient was diagnosed as HIV-positive, and status of antiretroviral therapy. Results. Anolunula was present in significantly more fingernails in HIV-positive patients compared to HIV-negative controls. There was a highly significant difference for total anolunula (anolunula in all fingernails) in study and control group. Incidence of total anolunula was directly proportional to the stage of HIV infection, increasing progressively as the HIV infection advances from stage 1 to stage 4. Conclusion. Absence of lunula is related to not only HIV infection per se but also the stages of HIV infection.

    Although oxidized low-density lipoprotein (LDL) and lysophosphatidylcholine (LPC) have been proposed as important mediators of the atherosclerosis, the long-term contribution to the risk of cardiovascular disease (CVD) in hemodialysis patients has not been evaluated. This study investigated the relation between oxidized LDL and LPC levels with long term risk of CVD. Plasma oxidized LDL and LPC levels were determined in 69 Korean hemodialysis patients as a prospective observational study for 5 yr. During the observation period, 18 cardiovascular events (26.1%) occurred including 6 deaths among the hemodialysis patients. The low LPC level group (≤ 254 µM/L, median value) had much more increased risk of CVD compared to the high LPC level group (> 254 µM/L) (P = 0.01). However, serum levels of oxidized LDL were not significantly different between groups with and without CVD. In adjusted Cox analysis, previous CVD, (hazard ratio [HR], 5.68; 95% confidence interval [CI], 1.94-16.63, P = 0.002) and low LPC level (HR, 3.45; 95% CI, 1.04-11.42, P = 0.04) were significant independent risk factors for development of CVD. It is suggested that low LPC, but not oxidized LDL, is associated with increased risk of CVD among a group of Korean hemodialysis patients.

  6. What are patient factors associated with the quality of diabetes care?: results from the Korean National Health and Nutrition Examination Survey

    2012-01-01

    Background Recently there has been a growing interest in healthcare quality control in Korea. We examined the association between patient factors and quality indicators of diabetic care among Korean adults with diabetes. Methods We obtained a sample of 335 adults aged 20 or older diagnosed with diabetes from the 2005 Korean National Health and Nutrition Examination Survey. Patient factors were divided into two categories: socioeconomic position and health-related factors. Quality indicators for diabetes care were defined as receiving preventive care services for diabetes complications (e.g., fundus examination, microalbuminuria examination, diabetes education) and diabetes-related clinical outcomes (e.g., HbA1c, blood pressure, LDL-cholesterol). We performed multiple logistic regression analyses for each quality indicator. Results We found that people with lower education levels or shorter duration of diabetes illness were less likely to receive preventive care services for diabetes complications. Women or people with longer duration of diabetes were less likely to reach the glycemic target. Obese diabetic patients were less likely to accomplish adequate control of blood pressure and LDL-cholesterol. Conclusions Several factors of patients with diabetes, such as education level, duration of illness, gender, and obesity grade are associated with the quality of diabetes care. These findings can help inform policy makers about subpopulations at risk in developing a public health strategy in the future. PMID:22913274

    Sepsis is an important and serious complication in hemodialysis (HD) patients. Here we report on a case of spina bifida with ventriculo-peritoneal (VP) shunt infection who was on HD and underwent at least 5 months of investigations before a source of the infection was found and eventually treated successfully. We believe this to be the first reported case of VP shunt-associated sepsis in a patient on HD.

  8. Translation and Validation of a Korean Version of the Xerostomia Inventory in Patients with Primary Sjögren’s Syndrome

    2016-01-01

    This study was conducted to generate and validate a cross-culturally adapted Korean version of the xerostomia inventory (XI), an 11-item questionnaire designed to measure the severity of xerostomia. The original English version of the XI was translated into Korean according to the guidelines for cross-cultural adaptation of health-related quality-of-life measures. Among a prospective cohort of primary Sjögren’s syndrome (pSS) in Korea, 194 patients were analyzed. Internal consistency was evaluated by using Cronbach’s alpha, and test-retest reliability was obtained by using an intraclass correlation coefficient (ICC) analysis. Construct validity was investigated by performing a correlation analysis between XI total score and salivary flow rate (SFR). Cronbach’s alpha for internal consistency was 0.868, and the ICC for test-retest reliability ranged from 0.48 to 0.827, with a median value of 0.72. Moderate negative correlations between XI score and stimulated SFR, unstimulated SFR, and differential (stimulated minus unstimulated) SFR were observed (Spearman’s rho, ρ = −0.515, −0.447, and −0.482, respectively; P < 0.001). The correlation analysis between the visual analogue scale (VAS) score of overall dryness and SFR indicated a smaller ρ value (−0.235 [P = 0.006], −0.243 [P = 0.002], and −0.252 [P = 0.003], respectively), which supports that XI more accurately reflects the degree of xerostomia in the pSS patients. In conclusion, the Korean version of the XI is a reliable tool to estimate the severity of xerostomia in patients with pSS. PMID:27134493

    Obesity is a disease threatening health and is known one of risk factors causing chronic disease. In Traditional Korean Medicine, bi-sup is casus of obesity. Wnt10b has been indicated as a potential regulator of adipogenesis in vivo and in vitro models of obesity. To analyze the distribution of wnt10b polymorphism between bi-sup group and non-bi-sup group in Korean elder subjects with cerebral infarction (CI). The study group was composed of patients with CIwho were admitted to one of the thirteen Korean oriental medical hospitals participating in this study from 2009 to 2010. A total of 670 CI patients, including 416 with bi-sup group and 254 with non-bi-sup group, participated in this study. Genotype of G-607C was conducted by primer extension using TaqManprobe and five percent of subjects were re-genotyped by direct sequencing to confirm the accuracy of the genotyping. The association of the SNP with the bi-sup group versus non-bi-sup group was performed by multiple logistic regression. Frequency of C allele in bi-sup was 45.75% which was significantly lower than 56.69% in non-bi-sup (P=0.0043, OR=0.628 [0.453-0.864]). Subjects with GC or CC type in bi-sup was also 72.36%, that was also small compared with 78.35% in non-bi-sup (P=0.0467, OR=0.675 [0.458-0.994]). These results suggest that G-607C might be used as a diagnostic genetic marker for bi-sup in stroke patients and in the development of personalized medical care. PMID:26885084

    Human polyomavirus BK virus (BKV) is a double-stranded DNA virus that infects approximately 90 % of the general population as a subclinical or mild infection. In immunosuppressed patients, such as HIV cases, BKV may be reactivated resulting hemorrhagic cystitis and tubulointerstitial nephritis. However, there are limited studies on prevalence and molecular epidemiology of BKV in Iran. We therefore aimed to evaluate the prevalence and subtypes of BKV in Iranian HIV patients. A total of 99 patients with HIV infection were enrolled in the study. Presence of BKV DNA in plasma was evaluated by nested PCR. PCR products were sequenced directly, and phylogenetic analysis was performed. BKV DNA was detected in 8.08 % of HIV patients. BKV viremia presented in 4 out of 25 patients (16 %) not receiving antiretroviral therapy in comparison with 4 out 74 of HAART-treated patients (5.4 %) (P = 0.023). In patients with CD4 counts ≥200 cells/mm(3), viremia was found more commonly (7/80 = 8.8 %) than in those with lower counts (1/19 = 5.2 %) (not significant). All sequenced BKV isolates belonged to subtype Ib-2. Our findings indicated that the prevalence of BKV viremia is relatively prevalent in patients with HIV infection and significantly higher in naïve than HAART-treated cases. Therefore, HAART can eliminate BKV infection from plasma and reduce viremia although the actual implication of BKV viremia in HIV patients is not clear.

    Since 2001, financial support has been provided for all patients with neuromuscular disease (NMD) who require ventilatory support due to the paralysis of respiratory muscles in Korea. The purpose of this study was to identify ventilator usage status and appropriateness in these patients. We included 992 subjects with rare and incurable NMD registered for ventilator rental fee support. From 21 February 2011 to 17 January 2013, ventilator usage information, regular follow-up observation, and symptoms of chronic hypoventilation were surveyed by phone. Home visits were conducted for patients judged by an expert medical team to require medical examination. Abnormal ventilatory status was assessed by respiratory evaluation. Chronic respiratory insufficiency symptoms were reported by 169 of 992 subjects (17%), while 565 subjects (57%) did not receive regular respiratory evaluation. Ventilatory status was abnormal in 102 of 343 home-visit subjects (29.7%). Although 556 subjects (56%) reported 24-hour ventilator use, only 458 (46%) had an oxygen saturation monitoring device, and 305 (31%) performed an airstacking exercise. A management system that integrates ventilator usage monitoring, counselling and advice, and home visits for patients who receive ventilator support could improve the efficiency of the ventilator support project.

    Craniofrontonasal syndrome (CFNS) is a very rare genetic disorder with variable clinical phenotypes, including brachycephaly, hypertelorism, and a bifid nasal tip. Moreover, longitudinal splittings of the nails and skeletal abnormalities may accompany this condition. CFNS is inherited in an X-linked dominant manner; however, affected heterozygous females exhibit additional and more severe manifestations compared with affected hemizygous males, paradoxically. Here, we report for the first time in Korea two girls with molecularly confirmed CFNS. They commonly showed the typical craniofacial manifestations of CFNS, whereas the severity and the type of associated anomalies differed between them, suggesting phenotypic diversity for this disease. One patient showed unilateral coronal synostosis, cleft palate, and septate uterus together with intellectual disability. The other patient exhibited bilateral coronal synostosis and normal developmental milestones, without anomalies in other organs. A Sanger sequencing analysis of these patients revealed one novel (IVS2+3G>T) and one previously reported mutation (p.Gly151Ser) in EFNB1 Both patients were de novo cases without a family history of CFNS.

    Paediatric respiratory tract infections are one of the most common reasons for physician visits and hospitalisation, and are associated with significant morbidity and mortality. The role of physicians and other healthcare professionals has expanded from merely treating disease to implementing measures aimed at health maintenance and disease prevention. Therefore, children with recurrent respiratory tract infections represent a great challenge for the paediatrician, from both therapeutic and preventive standpoints. The paediatrician must first determine whether these recurrent infections are because of host-derived factors or are the result of increased environmental exposure. Host-derived factors may be nonimmunological or related to host immunodeficiency. The leading cause of recurrent respiratory tract infections throughout the world is increased environmental exposure in children attending nursery school or daycare centres. Acute otitis media in children is of particular concern because of its high incidence, frequent recurrence, and serious long term sequelae, e.g. hearing loss. The socioeconomic impact of these recurrent infections is staggering, and there remains much scope for devising methods for their treatment and prevention. Recent approaches have included the encouragement of breastfeeding, the use of intravenous immunoglobulin and respiratory syncytical virus immune globulin, as well as methods of stimulating immunity, such as ribosomal immunotherapy.

    Abstract Objectives: to analyze the occurrence and predisposing factors for surgical site infection in patients submitted to heart transplantation, evaluating the relationship between cases of infections and the variables related to the patient and the surgical procedure. Method: retrospective cohort study, with review of the medical records of patients older than 18 years submitted to heart transplantation. The correlation between variables was evaluated by using Fisher's exact test and Mann-Whitney-Wilcoxon test. Results: the sample consisted of 86 patients, predominantly men, with severe systemic disease, submitted to extensive preoperative hospitalizations. Signs of surgical site infection were observed in 9.3% of transplanted patients, with five (62.5%) superficial incisional, two (25%) deep and one (12.5%) case of organ/space infection. There was no statistically significant association between the variables related to the patient and the surgery. Conclusion: there was no association between the studied variables and the cases of surgical site infection, possibly due to the small number of cases of infection observed in the sample investigated.

    SUMMARY Human adenoviruses (HAdVs) are an important cause of infections in both immunocompetent and immunocompromised individuals, and they continue to provide clinical challenges pertaining to diagnostics and treatment. The growing number of HAdV types identified by genomic analysis, as well as the improved understanding of the sites of viral persistence and reactivation, requires continuous adaptions of diagnostic approaches to facilitate timely detection and monitoring of HAdV infections. In view of the clinical relevance of life-threatening HAdV diseases in the immunocompromised setting, there is an urgent need for highly effective treatment modalities lacking major side effects. The present review summarizes the recent progress in the understanding and management of HAdV infections. PMID:24982316

    Healthcare-associated infections (HAIs) are an important cause of morbidity and mortality in the USA. They are associated with a substantial increase in health care costs each year. Fortunately, many HAIs are preventable, and their eradication is a national priority. Chlorhexidine (CHG) bathing has been used as an infection prevention measure, either alone or bundled with other interventions, with mostly beneficial results. The recent surge in its use as an agent of choice for skin antisepsis has lead to concerns over emerging resistance among microorganisms. Moreover, compliance with CHG-bathing protocols is not routinely monitored. Policies developed to determine the best infection prevention practice must consider that a "one-size-fits-all" strategy may lead to the selection of CHG-tolerant microorganisms, thereby emphasizing the need for more robust guidelines and additional studies on the role of chlorhexidine bathing for the prevention of HAIs.

For this study, 1046 HIV-positive patients were examined regarding psychoses. A total of 301 patients (28.8%) were HIV-positive but asymptomatic, and 380 patients (36.2%) had the lymphadenopathy syndrome. One hundred thirty-two patients (12.6%) suffered from an AIDS-related complex and 233 patients (22.3%) from AIDS. Of these 1046 patients, only 9 (0.9%) suffered from psychoses. One patient with a paranoid-hallucinatory syndrome was asymptomatic; one in the lymphadenopathy syndrome was manic. The other 7 patients were all in late stages of the infection. A causal relationship between HIV infection and psychosis and probable in only 3 patients. These data do not indicate a markedly elevated prevalence of psychosis in HIV-positive or AIDS patients.

    There is a growing need for kidney and liver transplants in persons living with HIV. Fortunately, with the significant advances in antiretroviral therapy and management of opportunistic infections, HIV infection is no longer an absolute contraindication for solid organ transplantation. Data from several large prospective multi-center cohort studies have shown that solid organ transplantation in carefully selected HIV-infected individuals is safe. However, significant challenges have been identified including prevention of acute rejection, management of drug-drug interactions and treatment of recurrent viral hepatitis. This article reviews the selection criteria, outcomes, and special management considerations for HIV-infected patients undergoing liver or kidney transplantation.

    Human metapneumovirus (hMPV) is considered an important cause of acute respiratory infections. hMPV can cause morbidity in hematopoietic stem cell transplant recipients and recent research has demonstrated that it is an important virus in patients admitted to hospital with respiratory infections and suspected of having pandemic 2009 influenza A (H1N1pdm09) virus. The purpose of this study was to investigate infections caused by hMPV in two groups of patients admitted to hospital: Immunocompromized patients with a potential risk of severe outcomes and immunocompetent patients with severe acute respiratory syndrome. A total of 288 samples were tested: 165 samples were collected from patients with suspected influenza A (H1N1) pdm09 infection during the first pandemic wave in 2009; and 123 samples were collected from patients of a hematopoietic stem cell transplantation program in 2008-2009. Amplification of the hMPV genes was performed by polymerase chain reaction. This was followed by sequencing and phylogenetic analysis. hMPV was detected in 14.2% (41/288) of all samples: 17% (28/165) of immunocompetent patients with suspected H1N1 infection and 10.6% (13/123) among hematopoietic stem cell transplant recipients. hMPV accounted for 12.1% (8/66) of immunocompetent adults patients with severe respiratory infections (median age, 55.9 years). Two hMPV subtypes were identified, A2 (26.9%; 7/26) and B2 (73.1%; 19/26) but no difference was observed between the patient groups in terms of age or immunosuppression level. This study highlights the significance of hMPV in immunocompetent adult patients with severe infections and further investigations are recommended for understanding the impact of this virus.

    The lifetime risk of dying from sepsis is approximately 2-3% in persons with (functional) asplenia. Both patients and their physicians are not always fully aware of these risks and the implementation of preventive measures is insufficient. Physicians should inform both patients and colleagues on the consequences of lost splenic function. Primary care physicians should screen their lists for patients with (functional) asplenia and offer these patient adequate preventive measures when needed. PMID:27650028

    Sera from a total of 268 patients with protozoan, helminth, bacterial (leprosy and tuberculosis) infections or appropriate controls, were assayed for anti-tubulin antibodies in an indirect enzyme-linked immunosorbent assay (ELISA), using purified tubulin as antigen. Levels of serum anti-tubulin antibody were significantly elevated in 67% of patients with visceral leishmaniasis, in 60% of patients with cutaneous leishmaniasis, in 89% of patients with onchocerciasis, in 100% of patients with schistosomiasis, and in 94% of patients with leprosy. Little or no increase in anti-tubulin antibody levels was seen in sera from patients with malaria (Plasmodium vivax) or tuberculosis. PMID:3115642

    Purpose Doxorubicin/cyclophosphamide followed by docetaxel chemotherapy (AC-D) is an intermediate risk factor (incidence of 10%–20%) for febrile neutropenia (FN) in breast cancer. However, the reported incidence of FN while using this regimen was obtained mostly from Western breast cancer patients, with little data available from Asian patients. This study aimed to assess the incidence of FN in Korean breast cancer patients and to describe clinical variables related to FN. Methods From September 2010 to February 2013, data from the Yonsei Cancer Center registry of breast cancer patients who received neoadjuvant or adjuvant chemotherapy with four cycles of AC-D (60 mg/m2 doxorubicin, 600 mg/m2 cyclophosphamide every 3 weeks for four cycles followed by 75 mg/m2 or 100 mg/m2 docetaxel every 3 weeks for four cycles) were analyzed. The incidence of FN, FN associated complications, dose reduction/delays, and relative dose intensity (RDI) were investigated. Results Among the 254 patients reported to the registry, the FN incidence after AC-D chemotherapy was 29.5% (75/254), consisting of 25.2% (64/254) events during AC and 4.7% (12/254) during docetaxel chemotherapy. Dose reductions, delays, and RDI less than 85.0% during AC were observed in 16.5% (42/254), 19.5% (47/254), and 11.0% (28/254) of patients, respectively. Patients with FN events frequently experienced dose reduction/delays, which eventually led to a decreased RDI. Conclusion The incidence of FN during AC-D neoadjuvant or adjuvant chemotherapy was higher than expected in Korean breast cancer patients. Whether these patients should be classified as a high-risk group for FN warrants future prospective studies. PMID:27064666

    The therapeutic dose of warfarin is dependent upon intrinsic patient characteristics that are highly variable. We assessed the effects of CYP2C9, VKORC1 1173 C/T polymorphisms, and old age on warfarin dosing and sensitivity by measuring plasma S-/R-warfarin levels in Korean patients. INR and the plasma S-/R-warfarin concentrations were determined in 58 patients who had the VKORC1 1173C/T CYP2C9 genotypes, were on a long-term anticoagulation regimen with warfarin, and took a daily dose of warfarin. The pharmacokinetic sensitivity of warfarin was significantly higher in the CYP2C9 *1/*3 genotypes than in the CYP2C9 *1/*1 genotypes [ratio of S-warfarin concentration/dose, 0.53 vs. 0.21; p=0.01]. Pharmacodynamic sensitivity in older patients (≥ 75 years) with the CYP2C9 *1/*1 and VKORC1 1173 TT genotypes was significantly higher as compared to younger patients (<75 years) [Ratio of INR/S-warfarin concentration, 4.88 vs. 3.41; p = 0.026]. The CYP2C9*3 allele and old age (≥ 75 years) with the VKORC1 1173 T allele were also associated with increased risk of over-anticoagulation. The increase of over-anticoagulation risk and warfarin sensitivity is related to the CYP2C9*3 allele and old age with the VKORC1 1173 T allele in Korean patients with thromboembolic disease. These findings suggest that a lower initial and maintenance dose should be considered for the patients with CYP2C9 *3 allele and advanced age in this patient population. However, due to the limited number of patients in the study population, our finding needs to be confirmed by a larger, well-controlled study. PMID:22075505

    Mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episode (MELAS) and myoclonic epilepsy and ragged-red fibers (MERRF) are rare disorders caused by point mutation of the tRNA gene of the mitochondrial genome. To understand the pathogenetic mechanism of MELAS and MERRF, we studied four patients. Serially sectioned frozen muscle specimens with a battery of histochemical stains were reviewed under light microscope and ultrastructural changes were observed under electron microscope. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis was performed and the tRNA genes were sequenced to confirm mutations. In two patients with MELAS, strongly succinyl dehydrogenase positive blood vessels (SSVs) and many cytochrome oxidase (COX) positive ragged-red fibers (RRFs) were observed, and A3243G mutations were found from the muscle samples. In two patients with MERRF, neither SSV nor COX positive RRFs were seen and A8344G mutations were found from both muscle and blood samples. In the two MERRF families, the identical mutation was observed among family members. The failure to detect the mutation in blood samples of the MELAS suggests a low mutant load in blood cells. The histochemical methods including COX stain are useful for the confirmation and differentiation of mitochondrial diseases. Also, molecular biological study using muscle sample seems essential for the confirmation of the mtDNA mutation. PMID:11850598

    Infection with Candida species remains a major problem in HIV infected patients. The analysis of over 15,000 hospitalisations (1985-2007) in the AVK cohort shows an increasing incidence of non-albicans species in candida esophagitis. Although our analysis shows a decreasing incidence of opportunistic infections like PCP, cerebral toxoplasmosis and others since the introduction of highly active antiretroviral therapy the incidence of candida esophagitis remains as high as in the years before the HAART era. This observation might reflect the development of resistance against fluconazole and the selection of non-albicans species as a consequence of a long-term prophylactic treatment of HIV+ patients over years.

    This article reports long-term infection and treatment failure in 18 symptomatic individuals infected with Blastocystis spp. Patients were initially treated with either metronidazole, iodoquinol or triple combination therapy consisting of nitazoxanide, furazolidone and secnidazole. Following treatment, resolution of clinical symptoms did not occur and follow-up testing revealed ongoing infection with the same subtype. Patients then underwent secondary treatment with a variety of antimicrobial agents but remained symptomatic with Blastocystis spp. still present in faeces. Sequencing of the SSU rDNA was completed on all isolates and four subtypes were identified in this group: ST1, ST3, ST4 and ST5. This study highlights the lack of efficacy of several commonly used antimicrobial regimens in the treatment of Blastocystis and the chronic nature of some infections. It also demonstrates the need for further research into treatment options for Blastocystis infection. PMID:24243286

    Renal disease is a common complication of HIV-infected patients, associated with increased risk of cardiovascular events, progression to AIDS, AIDS-defining illness, and mortality. Early and accurate identification of renal disease is therefore crucial to improve patient outcomes. The use of serum creatinine, along with proteinuria, to detect renal involvement is essentially to screen for markers of glomerular disease and may not be effective in detecting earlier stages of renal injury. Therefore, more sensitive and specific markers are needed in order to early identify HIV-infected patients at risk of renal disease. This review article summarizes some new and important urinary markers of tubular injury in HIV-infected patients and their clinical usefulness in the renal safety follow-up of TDF-treated patients.

    The magnitude and duration of dengue viraemia were studied in 153 patients with naturally acquired dengue infection in Jakarta, Indonesia. The duration of viraemia ranged from 2 to 12 days, but most patients had detectable circulating virus for 4-5 days. Accurate measurement of peak virus titres was not possible for many patients because of late admission to the hospital. Composite pictures of viraemia for each serotype, however, showed that many patients infected with dengue 1, 2, or 3 had circulating virus titres ranging from barely detectable to over 10(8) MID(50) per ml for 3-5 days. Virus titres in patients infected with dengue 4 were about 100-fold lower. Dengue haemagglutination-inhibition antibody titres of 80 or less had little effect on viraemia, but antibody titres of 160 or greater were associated with a decrease in virus isolation rate and in virus titre. The duration and magnitude of viraemia did not vary significantly with the severity of the disease and was only slightly higher in patients classified as primary dengue infections than in those classified as secondary infections. Measurement of viraemia in fatal dengue haemorrhagic fever (DHF) cases showed that these patients had significant quantities of circulating virus at the time of death.

    Abstract Optic nerve sheath diameter (ONSD) seen on ocular US has been associated with increased intracranial pressure (IICP). However, most studies have analyzed normal range of ONSD and its optimal cut-off point for IICP in Caucasian populations. Considering ONSD differences according to ethnicity, previous results may not accurately reflect the association between IICP and ONSD in Koreans. Therefore, we conducted this study to investigate normal range of ONSD and its optimal threshold for detecting IICP in Korean patients. This prospective multicenter study was performed for patients with suspected IICP. ONSD was measured 3 mm behind the globe using a 13-MHz US probe. IICP was defined as significant brain edema, midline shift, compression of ventricle or basal cistern, effacement of sulci, insufficient gray/white differentiation, and transfalcine herniation by radiologic tests. The results of the ONSD are described as the median (25th–75th percentile). The differences of ONSD according to disease entity were analyzed. A receiver operator characteristic (ROC) curve was generated to determine the optimal cut-off point for identifying IICP. A total of 134 patients were enrolled. The patients were divided into 3 groups as follows: patients with IICP, n = 81 (60.5%); patients without IICP, n = 27 (20.1%); and control group, n = 26 (19.4%). ONSD in patients with IICP (5.9 mm [5.8–6.2]) is significantly higher than those without IICP (5.2 mm [4.8–5.4]) (P < 0.01) and normal control group (4.9 mm [4.6–5.2]) (P < 0.001). Between patients without IICP and normal control group, the difference of ONSD did not reach statistical significance (P = 0.31). ONSD >5.5 mm yielded a sensitivity of 98.77% (95% CI: 93.3%–100%) and a specificity of 85.19% (95% CI: 66.3%–95.8%). In conclusion, the optimal cut-off point of ONSD for identifying IICP was 5.5 mm. ONSD seen on ocular US can be a feasible method for detection and serial monitoring of ICP in

    We describe a case of heparin binding site Arg79Cys mutation in the gene encoding antithrombin, SERPINC1, in a Korean patient with hereditary antithrombin (AT) deficiency. The patient was a 34-year-old Korean man who presented with deep vein thrombosis (DVT) in his right leg without precipitating factors. On outpatient evaluation, coagulation tests without anticoagulation revealed a decreased AT III activity level at 48%, but normal AT III antigen level at 103%, indicating type II AT deficiency. Family studies revealed that his father (62 years of age) had decreased AT activity (48%) but had normal AT antigen levels (116%), indicating that the proband had a paternally inherited type II AT deficiency. Direct sequencing of the SERPINC1 gene in the patient and his father revealed a heterozygotic missense mutation, a cytosine to thymine substitution at nucleotide position 235 in exon 2 of the SERPINC1 gene (p.Arg79Cys). To our knowledge, this is the first report of Arg79Cys heterozygote mutation in family members with venous thromboembolism.

    Pachydermoperiostosis (PDP), or primary hypertrophic osteoarthropathy, is a rare genetic disease affecting both skin and bones. Both autosomal dominant with incomplete penetrance and recessive inheritance of PDP have been previously confirmed. Recently, hydroxyprostaglandin dehydrogenase (HPGD) and solute carrier organic anion transporter family member 2A1 (SLCO2A1) were reported as pathogenic genes responsible for PDP. Both genes are involved in prostaglandin E2 (PGE2) degradation. We aimed to identify responsible genes for PDP and the clinical features in Korean patients with PDP. Six affected individuals and their available healthy family members from three unrelated Korean families with PDP were studied. All of the patients displayed complete phenotypes of PDP with finger clubbing, pachydermia, and periostosis. Mutation analysis revealed a novel heterozygous mutation in the SLCO2A1 gene at nucleotide 302 causing a substitution of the amino acid isoleucine to serine at codon 101 (p.IIe101Ser) in affected individuals. We also identified known SLCO2A1 mutations, one homozygous for c.940+1G>A, and another compound heterozygous for c.940+1G>A and c.1807C>T (p.Arg603*) from two PDP families. Genetic analyses of the PDP patients showed no abnormality in the HPGD gene. Our study further supports the role of mutations in the SLCO2A1 gene in the pathogenesis of PDP and could provide additional clues to the genotype-phenotype relations of PDP. PMID:27134495

    Because there are clear molecular differences entailing different treatment effectiveness between Korean and non-Korean cancer patients, identifying distinct molecular characteristics of Korean cancers is profoundly important. Here, we report a web-based data repository, namely Korean Cancer Genome Database (KCGD), for searching gene signatures associated with Korean cancer patients. Currently, a total of 1,403 cancer genomics data were collected, processed and stored in our repository, an ever-growing database. We incorporated most widely used statistical survival analysis methods including the Cox proportional hazard model, log-rank test and Kaplan-Meier plot to provide instant significance estimation for searched molecules. As an initial repository with the aim of Korean-specific marker detection, KCGD would be a promising web application for users without bioinformatics expertise to identify significant factors associated with cancer in Korean.

    In order to provide safe and secure medical care for patients, health care-associated infections (HAI) must not occur. HAI should be considered as incidents, and countermeasures should be viewed as a patient safety management itself. Healthcare-associated infection control (HAIC) is practiced by the infection control team (ICT), which is based on multidisciplinary cooperation. Team members have to recognize that it is the most important to make use of the expertise of each discipline. In addition, all members must try to respond quickly, to help the clinic staff. Visualized rapid information provision and sharing, environmental improvement, outbreak factor analysis, hand hygiene compliance rate improvement, proper antibiotic use (Antimicrobial Stewardship Program: ASP), and regional cooperation & leadership comprise the role of the ICT in the flagship hospital. Regarding this role, we present our hospital's efforts and the outcomes. In conclusion, for medical practice quality improvement, healthcare-associated infection control should be conducted thoroughly along with an awareness of patient safety.

    Purpose of the Review Substance use may persist throughout the life course and has a substantial impact on health outcomes globally. As HIV-infected individuals are disproportionately impacted by substance use and living longer, it is critical that providers and researchers alike understand the impact of substance use on older, HIV-infected patients and potential treatment options. To this end, we conducted a review of the literature focusing on the most commonly used substances to outline the epidemiology, health consequences, treatment options and latest research relevant to older, HIV-infected patients. Recent Findings Substance use impacts older, HIV-infected patients with regards to HIV-related and non-HIV related outcomes. Counseling strategies are available for marijuana and stimulant use disorders. Brief counseling is useful alongside medications for alcohol, tobacco and opioid use disorders. Many medications for alcohol, tobacco, and opioid use disorders are safe in the setting of antiretroviral therapy. Unfortunately, few interventions targeting substance use in older, HIV-infected patients have been developed and evaluated. Summary As older, HIV-infected patients continue to experience substance use and its related health consequences, there will be a growing need for the development of safe and effective interventions which address the complex needs of this population.

    We investigated the clinical and laboratory characteristics of pregnancies with systemic lupus erythematosus (SLE) and identified lupus flare predictors during pregnancy. Additionally, we examined lupus activity and pregnancy outcomes in SLE patients who continued, discontinued or underwent no hydroxychloroquine (HCQ) treatment during pregnancy. We retrospectively analyzed 179 pregnancies in 128 SLE patients at Seoul St. Mary's Hospital, Korea, between 1998 and 2012 and then assessed the clinical profiles and maternal and fetal outcomes. Overall, 90.5% of pregnancies resulted in a successful delivery and were divided into two groups: those who experienced lupus flares (80 pregnancies, 44.7%) and those who did not (99 pregnancies, 55.3%). Increased preeclampsia, preterm births, low birth weight, intrauterine growth restriction (IUGR), and low 1-minute Apgar scores occurred in pregnancies with lupus flares compared to pregnancies in quiescent disease. Lupus flares were predicted by HCQ discontinuation, a history of lupus nephritis, high pre-pregnancy serum uric acid and low C4 levels. Our study indicates that achieving pre-pregnancy remission and continuing HCQ treatment during pregnancy are important for preventing lupus flares.

    The target of the case study was to investigate the efficiency of an alternative combined therapy scheme of herpes simplex infections versus the routine therapy by acyclovir or famvir as applicable to HIV-infected patients. leukinferon was shown to induce the antoherpetic acyclovir efficiency. The use of the latter concurrently with cycloferon for the treatment of infections provoked by herpes simple virus-1 (HSV-1) and HSV-2 in HIV-infected patients prolongs the remission period in case of the above opportunistic infections. The leukinferon anti-herpetic efficiency is, obviously, related with the phagocytosis stimulation and with its positive influence exerted on hemopoiesis. The combined therapy can be stated to be most effective in HIV, clinical stages B1 and 2.

    Until few years ago, HIV infection was an absolute contraindication to consider organ transplants. Since HAART introduction, patient survival increased dramatically, but high mortality due to liver and kidney diseases became evident. For these reasons, this group of patients is now reconsidered for organ transplantation. In 2008, the Argentine Society of Transplants (SAT) and the Argentine Infectious Diseases Society (SADI), encouraged by the increasing published experience on kidney and liver transplants in this population, decided to form a Working Group, to prepare an update on this issue and elaborate practical recommendations for the better management of these patients. The first meeting was held on December 4th 2008. The most important conclusion was that HIV infection did not contraindicate a solid organ transplant. Later on, taking into account the accumulated experience and the available literature, the current document was prepared. HIV infected patients must fulfill certain clinical, immunological, virological and psychosocial criteria to be considered for solid organ transplants. HIV infected recipients of kidney and liver transplants currently show similar short and middle term survival to non HIV infected patients. There is not yet enough data on intrathoracic transplants in these patients in order to include them on a waiting list for these organs-transplants. Interactions between immunosupressors and antiretroviral drugs (specially protease inhibitors) are very important, and require a strict monitoring of immunosupressor levels.

    During a 20-month period all acute nonlymphocytic patients (87 patient trials) receiving cytotoxic chemotherapy were placed on an oral nonabsorbable antibiotic regimen consisting of gentamicin, vancomycin, and nystatin in addition to an intensive program of infection prevention aimed at reducing exogenously acquired and body-surface potential pathogens. Although side effects of anorexia, diarrhea, and nausea were common, gentamicin-vancomycin-nystatin was ingested 80% of the study time. Microbial growth in gingival and rectal cultures was substantially reduced. The incidence of bacteremias and other serious infections was low. Pseudomonas aeruginosa, other gram-negative bacilli, and Candida species caused few infections along the alimentary canal, whereas infections of the skin (especially Staphylococcus aureus) were not reduced compared with those occurring in former years. A total of the 104 acquired gram-negative bacilli were gentamicin resistant; 5 subsequently caused infection. Thus, despite certain definite drawbacks, the use of oral nonabsorbable antibiotics to suppress alimentary tract microbial flora in combination with other infection prevention techniques in granulocytopenic cancer patients has proven feasible and tolerable and has been associated with a low order of life-threatening infections.

    Epidemiological evidence implicates bacterial infection as a common triggering stimulus for psoriasis. Recent studies suggest that continuing, subclinical streptococcal and staphylococcal infections might be responsible not only for relapse of acute guttate psoriasis but also for a new episode of chronic plaque psoriasis. In this study 195 patients suffering from a severe form of chronic plaque psoriasis hospitalized between 1996 and 1998 were examined. The presence of subclinical microbial infection of the upper respiratory tract was studied by the cultivation of pathogens from this area. Patients with other provoking factors, such as a positive history of taking any drugs that may exacerbate psoriasis, endocrine and metabolic factors, alcohol abuse, trauma, dental focus and clinically evident bacterial infection, were excluded. Subclinical streptococcal and/or staphylococcal infections were detected in 68% of tested patients and in only 11% of the control group. The results of this study indicate that subclinical bacterial infections of the upper respiratory tract may be an important factor in provoking a new relapse of chronic plaque psoriasis. Searching for, and eliminating, microbial infections could be of importance in the treatment of psoriasis.

    The Prevention of Orthopaedic Implant Infection in Patients Undergoing Dental Procedures evidence-based clinical practice guideline was codeveloped by the American Academy of Orthopaedic Surgeons (AAOS) and the American Dental Association. This guideline replaces the previous AAOS Information Statement, "Antibiotic Prophylaxis in Bacteremia in Patients With Joint Replacement," published in 2009. Based on the best current evidence and a systematic review of published studies, three recommendations have been created to guide clinical practice in the prevention of orthopaedic implant infections in patients undergoing dental procedures. The first recommendation is graded as Limited; this recommendation proposes that the practitioner consider changing the long-standing practice of routinely prescribing prophylactic antibiotic for patients with orthopaedic implants who undergo dental procedures. The second, graded as Inconclusive, addresses the use of oral topical antimicrobials in the prevention of periprosthetic joint infections. The third recommendation, a Consensus statement, addresses the maintenance of good oral hygiene.

    The present study was performed to report 15 anisakiasis cases in Korea and to review the Korean cases reported in the literature. Total 32 Anisakis type I larvae were detected in the stomach of 15 patients by the endoscopy. Single worm was detected from 12 cases, and even 9 larvae were found from 2 cases. Epigastric pain was most commonly manifested in almost all cases, and hemoptysis and hematemesis were seen in 1 case each. Symptom manifestations began at 10-12 hr after eating fish in 73.3% cases. Endoscopy was performed 1-2 days after the symptom onset in most cases. The common conger, Conger myriaster, was the probable infection source in 7 cases. In the review of Korean anisakiasis cases, thus far, total 645 cases have been reported in 64 articles. Anisakis type I larva was the most frequently detected (81.3%). The favorable infection site of larvae was the stomach (82.4%). The common conger was the most probable source of human infections (38.6%). Among the total 404 cases which revealed the age and sex of patients, 185 (45.8%) were males, and the remaining 219 (54.2%) were female patients. The age prevalence was the highest in forties (34.7%). The seasonal prevalence was highest in winter (38.8%). By the present study, 15 cases of gastric anisakiasis are added as Korean cases, and some epidemiological characteristics of Korean anisakiasis were clarified. PMID:26323845

    The increasing incidence of skin and soft tissue infections requires family physicians to be familiar with the management of these conditions. Evidence of systemic infection, such as fever, tachycardia, and hypotension, is an indication for inpatient management. Urgent surgical referral is imperative for those with life-threatening or rapidly advancing infections. In patients with uncomplicated abscesses measuring less than 5 cm in diameter, surgical drainage alone is the primary therapeutic intervention. Wound irrigation using tap water has similar outcomes as irrigation using sterile water. When antimicrobials are indicated, choice of agents depends on local resistance and susceptibility patterns. In settings where suspicion of methicillin-resistant Staphylococcus aureus (MRSA) is low, beta-lactam antibiotics are the first-line treatments for uncomplicated skin and soft tissue infections without focal coalescence or trauma. When empiric coverage for MRSA is indicated and the infection is uncomplicated, oral agents, such as tetracyclines, trimethoprim/sulfamethoxazole, and clindamycin, are preferred. Vancomycin is the first-line agent for MRSA in hospitalized patients, and newer agents, such as linezolid, daptomycin, and tigecycline, should be reserved for patients who do not respond to or cannot tolerate vancomycin therapy. There are insufficient data to support eradicating the carrier state in patients with MRSA or their contacts with nasal mupirocin or antibacterial body washes. Standard infection-control precautions, including proper and frequent handwashing, are a mainstay of MRSA prevention.

    The aim of the study was to assess the association between usual dietary nutrient intake and obesity in Korean type 2 diabetic patients. We examined 2,832 type 2 diabetic patients from the Korean National Diabetes Program cohort who completed dietary assessment and clinical evaluation in this cross-sectional study. In men, higher dietary fiber intake was associated with a lower odds of being obese (Ptrend = 0.003) and in women, higher protein intake was associated with a lower odds of being obese (Ptrend = 0.03) after adjustment for age, diabetes duration, HbA1c, alcohol drinking, income, education level, and calorie intake. In men, higher fiber intake was associated with lower odds of obesity after further adjustment for diastolic blood pressure, physical activity, and possible confounding nutritional intake and medication. The multivariable adjusted odds ratio for the highest quintile of fiber intake was 0.37 (Ptrend < 0.001). In women, protein intake was not associated with obesity after further adjustment. In conclusion, higher intake of dietary fiber is associated with lower odds of being obese in type 2 diabetic men, suggesting a role for dietary fiber in the management and prevention of obesity in type 2 diabetes (ClinicalTrials.gov: NCT 01212198).

    A retrospective survey of nocardia and actinomyces infections in five local hospitals was conducted over a 3-year period in El Paso, Texas, a border city, in the southwestern United States. The medical records of 42 patients with suspected nocardiosis or actinomycosis were reviewed. One patient was diagnosed with actinomyces and 12 patients with nocardia. Microbiological data included morphologic characteristics, biochemical profile, and susceptibility testing. Predisposing factors included leukemia, renal insufficiency, renal transplant, and lymphoma. No predisposing factors were found in 67% (n = 8) of patients (including the patient with actinomycosis). Twenty-three percent (n = 3) of patients had disseminated disease without evidence of underlying disease or immunosuppression. The mortality and morbidity of these infections appeared to be low.

    The dramatic change of the natural history of HIV-infected patients by highly active antiretroviral therapy (HAART) has exposed these patients to cardiovascular risk, including cardiovascular disease and hypertension. In HIV-infected patients, the development of arterial hypertension, at least in the medium-long term is an established feature, although recognized predictors of its development have not been clearly identified. In addition, conflicting data regarding the influence of antiretroviral therapy (ART) are reported. The presence of a proinflammatory state and oxidative stress-mediated endothelial dysfunction seem, however, to play a pathophysiologic role. In this review, we examine and provide a comprehensive, literature based, consideration of the pathophysiologic aspects of hypertension in these patients. HIV-infected patients, independently of the presence of hypertension, remain at very high cardiovascular risk due to the presence of the same cardiovascular risk factors recognized for the general population with, in addition, the indirect influence of the ART, essentially via its effect on lipid metabolism. This review based on the evidence from the literature, concludes that the management of HIV-infected patients in terms of cardiovascular prevention emerges as a priority. The consideration of cardiovascular risk in these patients should receive the same emphasis given for the general population at high cardiovascular risk, including adequate blood pressure control according to international guidelines.

    In this study, genetic analysis was conducted to investigate the association of angiotensin I converting enzyme (ACE) gene polymorphism with clinical phenotype based on differentiation-syndrome of bronchial asthma patients. Differentiation-syndrome is a traditional Korean medicine (TKM) theory in which patients are classified into a Deficiency Syndrome Group (DSG) and an Excess Syndrome Group (ESG) according to their symptomatic classification. For this study, 110 participants were evaluated by pulmonary function test. Among them, 39 patients were excluded because they refused genotyping. Of the remaining patients, 52 with DSG of asthma (DSGA) and 29 with ESG of asthma (ESGA), as determined by the differentiation-syndrome techniques were assessed by genetic analysis. ACE insertion/deletion (I/D) polymorphism analysis was conducted using polymerase chain reaction (PCR). Student's t, chi-square, Fisher and Hardy-Weinberg equilibrium tests were used to compare groups. No significant differences in pulmonary function were observed between DSGA and ESGA. The genotypic frequency of ACE I/D polymorphism was found to differ slightly between DSGA and ESGA (P = .0495). However, there were no significant differences in allelic frequency observed between DSGA and ESGA (P = .7006, OR = 1.1223). Interestingly, the allelic (P = .0043, OR = 3.4545) and genotypic (P = .0126) frequencies of the ACE I/D polymorphism in female patients differed significantly between DSGA and ESGA. Taken together, the results presented here indicate that the symptomatic classification of DSGA and ESGA by differentiation-syndrome in Korean asthma patients could be useful in evaluation of the pathogenesis of bronchial asthma.

    Infections cause significant morbidity and mortality in patients undergoing hemodialysis. Bloodstream infections (BSIs) are particularly problematic, accounting for a substantial number of hospitalizations in these patients. Hospitalizations for BSI and other vascular access infections appear to have increased dramatically in hemodialysis patients since 1993. These infections frequently are related to central venous catheter (CVC) use for dialysis access. Regional initiatives that have shown successful decreases in catheter-related BSIs in hospitalized patients have generated interest in replicating this success in outpatient hemodialysis populations. Several interventions have been effective in preventing BSIs in the hemodialysis setting. Avoiding the use of CVCs in favor of access types with lower associated BSI risk is among the most important. When CVCs are used, adherence to evidence-based catheter insertion and maintenance practices can positively influence BSI rates. In addition, facility-level surveillance to detect BSIs and stimulate examination of vascular access use and care practices is essential to a comprehensive approach to prevention. This article describes the current epidemiology of BSIs in hemodialysis patients and effective prevention strategies to decrease the incidence of these devastating infections.

    Surveys of yellowing viruses in plastic tunnels and in open field crops of melon (Cucumis melo cultivar catalupo), oriental melon (C. melo cultivar oriental melon), and cucumber (C. sativus) were carried out in two melon-growing areas in 2014, Korea. Severe yellowing symptoms on older leaves of melon and chlorotic spots on younger leaves of melon were observed in the plastic tunnels. The symptoms were widespread and included initial chlorotic lesions followed by yellowing of whole leaves and thickening of older leaves. RT-PCR analysis using total RNA extracted from diseased leaves did not show any synthesized products for four cucurbit-infecting viruses; Beet pseudo-yellows virus, Cucumber mosaic virus, Cucurbit yellows stunting disorder virus, and Melon necrotic spot virus. Virus identification using RT-PCR showed Cucurbit aphid-borne yellows Virus (CABYV) was largely distributed in melon, oriental melon and cucumber. This result was verified by aphid (Aphis gossypii) transmission of CABYV. The complete coat protein (CP) gene amplified from melon was cloned and sequenced. The CP gene nucleotide and the deduced amino acid sequence comparisons as well as phylogenetic tree analysis of CABYV CPs showed that the CABYV isolates were undivided into subgroups. Although the low incidence of CABYV in infections to cucurbit crops in this survey, CABYV may become an important treat for cucurbit crops in many different regions in Korea, suggesting that CABYV should be taken into account in disease control of cucurbit crops in Korea.

    Pneumocystis jiroveci (formerly P. carinii) is an opportunistic fungus responsible for pneumonia in immunocompromised patients. Pneumocystosis in non-HIV-infected patients differs from AIDS-associated pneumocystosis in mostly two aspects: diagnosis is more difficult, and prognosis is worse. Hence, efforts should be made to target immunocompromised patients at higher risk of pneumocystosis, so that they are prescribed long-term, low-dose, trimethoprime-sulfamethoxazole, highly effective for pneumocystosis prophylaxis. Patients at highest risk include those with medium and small vessels vasculitis, lymphoproliferative B disorders (chronic or acute lymphocytic leukaemia, non-Hodgkin lymphoma), and solid cancer on long-term corticosteroids. Conversely, widespread use of prophylaxis in all patients carrier of inflammatory diseases on long-term corticosteroids is not warranted. The management of pneumocystosis in non-AIDS immunocompromised patients follows the rules established for AIDS patients. The diagnosis relies on the detection of P. jiroveci cyst on respiratory samples, while PCR does not reliably discriminate infection from colonization, in 2015. High-doses trimethoprim-sulfamethoxazole is, by far, the treatment of choice. The benefit of adjuvant corticosteroid therapy for hypoxic patients, well documented in AIDS patients, has a much lower level of evidence in non-HIV-infected patients, most of them being already on corticosteroid by the time of pneumocystosis diagnosis anyway. However, based on its striking impact on morbi-mortality in AIDS patients, adjuvant corticosteroid is recommended in hypoxic, non-HIV-infected patients with pneumocystosis by many experts and scientific societies.

    An elderly female patient with an uncomplicated urinary tract infection from Salmonella newport is presented. Radiological and laboratory studies were performed because of her systemic and exposure risk factors as well as prior urinary tract abnormalities. While this patient was successfully treated as an outpatient with oral antibiotics, complications and recurrence are common and deserve close follow-up with repeat urine cultures at a minimum. Further laboratory and radiological testing should be guided by patient gender, risk factors and recurrence. PMID:25193813

    Abstract: Infective dermatitis is a chronic exudative eczematous eruption presenting in human T-lymphotropic virus type 1 (HTLV-1)–infected people. It presents with relapsing erythematous, scaly, and crusted lesions affecting simultaneously the scalp, external ear, retroauricular area, eyelid, paranasal skin, neck axilla, and groin. Superimposed Staphylococcus and Streptococcus infection are common. It mainly affects children and exceptionally adults, and there are only a few published cases. The authors present the first reported case in Paraguay of an adult patient who had symptoms of human T-lymphotropic virus type 1–associated progressive tropical spastic paraparesis, and 6 years after the onset of the neurological symptoms, the patient developed infective dermatitis lesions on the skin, with frequent exacerbations since then.

    Dengue infection is a major public health problem, affecting the general population in Southeast Asia. Hematologic aberrations in dengue infection include atypical lymphocytosis, coagulopathy, and predominant thrombocytopenia. Bleeding and other presentations in 30 Thai patients with dengue infection during an endemic season (2003) are presented. A review of the clinical presentation of these patients was performed. All had fever as a chief complaint. The three most common complaints were fever (100%), vomiting (90%), and cough (90%), respectively. Concerning bleeding, only eight cases (26.6%) had signs of bleeding. Those manifestations included petechiae (seven cases, 23.3%) and melena (one case, 3.3%). Skin bleeding (petechiae) due to thrombocytopenia is the most common bleeding manifestation in dengue infection. However, physicians should not overlook bleeding from other less common sites such as the gastrointestinal tract and genitourinary tract.

    Bone and soft tissue infection in the foot of diabetic patients is a well-described issue in the literature. A sound anatomical knowledge of the foot anatomy and compartments is mandatory to understand the mechanisms of infection spread. We describe four cases of diabetic foot infection complicated by long ascending infection. All did not respond initially to antibiotic treatment and the usual surgical debridement and were cured only after excision of the infected tendons. We highlight a rare but serious complication of the diabetic foot disease not commonly seen by the surgical community. We hope that this report raises the awareness of this condition so that a prompt diagnosis is made and appropriate treatment started, thereby reducing the risk of major lower limb amputations.

    Hepatitis B surface antigen is widely used in hepatitis B virus surveillance; patients who test negative for the antigen are judged to be uninfected. However, occult hepatitis B virus infection has been confirmed with hepatitis B virus DNA at low levels in the liver and peripheral blood in patients positive for hepatitis B core antibody or hepatitis B surface antibody, even if they test negative for hepatitis B surface antigen. To investigate the prevalence of occult hepatitis B virus in hemodialysis patients, we performed cross-sectional analysis of 161 hemodialysis patients in two related institutions for hepatitis B surface antigen, hepatitis B core antibody, and hepatitis B surface antibody. Hepatitis B surface antigen, hepatitis B core antibody, or hepatitis B surface antibody was present in 45 patients (28.0%). Hepatitis B virus DNA was present in six patients (3.7%), all of whom also tested positive for hepatitis B core antibody. Hepatitis B surface antibody positivity was unrelated in only one of the six patients. Four of the six patients were positive for hepatitis B surface antigen; however, two (1.3%) of these with occult hepatitis B virus infection were found to be hepatitis B surface antigen negative. Occult hepatitis B virus infection may be missed in hepatitis B virus surveillance using hepatitis B surface antigen alone; therefore, routine hepatitis B core antibody screening is necessary. Patients who test positive for hepatitis B core antibody should undergo further hepatitis B virus DNA testing to enable accurate hepatitis B virus screening.

    Over 100 HIV-infected patients have initiated chronic dialysis at San Francisco General Hospital (SFGH) since 1985. This study employed retrospective analysis to identify determinants of and trends in survival among HIV-infected patients who have initiated chronic dialysis at SFGH from January 1, 1985 to November 1, 2002 (n = 115). Cohort patient survival was compared with survival after an AIDS-opportunistic illness in all HIV-infected patients in San Francisco during the study period. Higher CD4 count (hazard ratio [HR], 0.86 per 50 cells/mm(3) increase; 95% confidence interval [CI], 0.80 to 0.93) and serum albumin (HR, 0.53 per 1 g/dl increase; CI, 0.36 to 0.78) at initiation of dialysis were strongly associated with lower mortality. Survival for those initiating dialysis during the era of highly active antiretroviral therapy (HAART) was 16.1 mo versus 9.4 mo for those initiating dialysis before this time, but this difference was not statistically significant. In adjusted analysis, only a non-statistically significant trend toward improved survival during the HAART era was noted (HR, 0.59; CI, 0.34 to 1.04). By comparison, survival for all HIV-infected patients after an AIDS-opportunistic illness in San Francisco increased from 16 mo in 1994 to 81 mo in 1996. The dramatic improvement in survival that has occurred since the mid-1990s for patients with HIV appears to be greatly attenuated in the sub-group undergoing dialysis. Although this may partly reflect confounding by race, injection drug use and HCV co-infection, future attempts to improve survival among HIV-infected dialysis patients should focus on barriers to the effective use of HAART in this group.

    HEV infection is an emerging public health problem worldwide Data concerning HEV infection in HIV+ patients in Greece is scare. The aim of the study was to determine HEV seroprevalence in patients with HIV infection in Greece. We studied 243 HIV(+) patients 214 men (88%) and 29 women (12%) with a median age of 45 years (range 19-83) who attended the HIV unit of Pathophysiology Department of Laikon General Hospital in Athens for the presence of anti-HEV IgG antibodies with (EIA) (EIA HEV IgG, Adaltis, Rome, Italy Eighteen/243 patients (7.3%) were positive for HEV IgG antibodies, a seroprevalence that was not different from that described for the blood donors group from Greece There was no difference of the presence of HbsAg, hepatitis C and hepatitis A between the HEV(+) and HEV(-) patients. There was no statistically significant difference between the HEV(+) and HEV(-) group in terms of HIV acquisition, sexual orientation, median duration of HIV infection, ART treatment, or duration of ART. Only the median age of HEV(+) was 52 years (35-78) while that of HEV(-) was 44 years (19-83)(P = 0.03). Only 2/18(11.1%) HEV(+) HIV(+) patients had abnormal ALT and AST values. The seroprevalence of hepatitis E in HIV(+) patients in Greece seems to be the same with that of the general population thus implying that HIV infection is not a risk factor for HEV infection and only age shows a positive correlation with seropositivity.

    Patient's perceptions of risk from bloodborne viruses (BBVs) and variant Creutzfeldt-Jacob Disease (vCJD) in relation to attendance at dental practice is understudied. This survey of an opportunistic sample of 50 dental practice patients examined patients' perceptions of the risk of acquiring BBVs and vCJD following dental treatment. Major concerns of patients revolved around hand hygiene practices rather than risks from BBVs or vCJD. No patient had avoided or delayed a visit to the dentist because of concerns over risks of cross infection.

    Background and Objectives We conducted a review of current data on respiratory syncytial virus (RSV) prophylaxis with palivizumab, in Korean children with congenital heart diseases (CHD). In 2009, the Korean guideline for RSV prophylaxis had established up to five shots monthly per RSV season, only for children <1 year of age with hemodynamic significance CHD (HS-CHD). Subjects and Methods During the RSV seasons in 2009-2015, we performed a retrospective review of data for 466 infants with CHD, examined at six centers in Korea. Results Infants received an average of 3.7±1.9 (range, 1-10) injections during the RSV season. Fifty-seven HS-CHD patients (12.2%) were hospitalized with breakthrough RSV bronchiolitis, with a recurrence in three patients, one year after the initial check-up. Among patients with simple CHD, only five (1.1%) patients received one additional dose postoperatively, as per the limitations set by the Korean guideline. Among the 30 deaths (6.4%), five (1.1%) were attributed to RSV infection; three to simple CHD, one to Tetralogy of Fallot, and one to hypertrophic cardiomyopathy (HCM). Of the three HCM patients that exceeded guidelines for RSV prophylaxis, two (66.6%) were hospitalized, and one died of RSV infection (33.3%). Conclusion In accordance to the Korean guideline, minimal injections of palivizumab were administered to patients having HS-CHD infection remains significant among children with simple CHD, cardiomyopathy, and children above the age of one year with HS-CHD.

    Sweet's syndrome is an uncommon dermatosis and can be associated with a wide variety of illnesses including infections and malignancies. Sweet's syndrome as a dermatological manifestation in human immunedeficiency virus (HIV) infection is rarely reported. Furthermore, called acute febrile neutrophilic dermatosis is characterized by fever and skin lesions, which are often erythematous papules and pseudovesicles. Diagnosis is based on clinical features and histology. The gold standard for treatment is systemic steroids although many other medications have been tried with variable success. We here report a case of Sweet's syndrome in an HIV-infected patient. PMID:26396453

    The interface of multiple sclerosis (MS) and infection occurs on several levels. First, infectious disease has been postulated as a potential trigger, if not cause, of MS. Second, exacerbation of MS has been well-documented as a consequence of infection, and, lastly, infectious diseases have been recognized as a complication of the therapies currently employed in the treatment of MS. MS is a disease in which immune dysregulation is a key component. Examination of central nervous system (CNS) tissue of people affected by MS demonstrates immune cell infiltration, activation and inflammation. Therapies that alter the immune response have demonstrated efficacy in reducing relapse rates and evidence of brain inflammation on magnetic resonance imaging (MRI). Despite the altered immune response in MS, there is a lack of evidence that these patients are at increased risk of infectious disease in the absence of treatment or debility. Links between infections and disease-modifying therapies (DMTs) used in MS will be discussed in this review, as well as estimates of occurrence and ways to potentially minimize these risks. We address infection in MS in a comprehensive fashion, including (1) the impact of infections on relapse rates in patients with MS; (2) a review of available infection data from pivotal trials and postmarketing studies for the approved and experimental DMTs, including frequency, types and severity of infections; and (3) relevant risk minimization strategies, particularly as they pertain to progressive multifocal leukoencephalopathy (PML).

    Introduction Helicobacter pylori is a gram-negative urease-producing bacterium causally linked with gastritis, peptic ulcer disease and gastric adenocarcinoma. Infection is more frequent and acquired at an earlier age in developing countries compared to European populations. The incidence of Helicobacter pylori infection in dyspeptic Ghanaian patients was 75.4%. However, epidemiological factors associated with infection vary across populations. Methods This study used a cross-sectional design to consecutively sample dyspeptic patients at the Endoscopy Unit of the Korle-Bu Teaching Hospital, Accra between 2010 and 2012. The study questionnaire elicited their epidemiological clinical characteristics. Helicobacter pylori infection was confirmed by rapid-urease examination of antral biopsies at upper Gastro-intestinal endoscopy. Results The sample population of dyspeptic patients attending the Endoscopy Unit for upper GI endoscopy yielded 242 patients of which 47.5% were females. The age distribution of H. pylori-infection was even across most age – groups, ranging from 69.2% (61 – 70) years to 80% (21 – 30) years. Helicobacter pylori prevalence decreased across areas mapping to the three residential classes in accordance with increasing affluence with rural areas having the highest prevalence. The unemployed and patients in farming had relatively high Helicobacter pylori infection rates of 92.3% and 91.7% respectively. Conclusion Helicobacter pylori is endemic in Ghana but the persistently high prevalence across age groups despite significant community anti-microbial use suggests likely re-crudescence or re-infection from multiple sources in a developing country. Socio-cultural factors such as residential class and farming may be facilitating factors for its continued prevalence. PMID:26430475

    AIM: To describe the intensive care unit (ICU) outcomes of critically ill cancer patients with Acinetobacter baumannii (AB) infection. METHODS: This was an observational study that included 23 consecutive cancer patients who acquired AB infections during their stay at ICU of the National Cancer Institute of Mexico (INCan), located in Mexico City. Data collection took place between January 2011, and December 2012. Patients who had AB infections before ICU admission, and infections that occurred during the first 2 d of ICU stay were excluded. Data were obtained by reviewing the electronic health record of each patient. This investigation was approved by the Scientific and Ethics Committees at INCan. Because of its observational nature, informed consent of the patients was not required. RESULTS: Throughout the study period, a total of 494 critically ill patients with cancer were admitted to the ICU of the INCan, 23 (4.6%) of whom developed AB infections. Sixteen (60.9%) of these patients had hematologic malignancies. Most frequent reasons for ICU admission were severe sepsis or septic shock (56.2%) and postoperative care (21.7%). The respiratory tract was the most frequent site of AB infection (91.3%). The most common organ dysfunction observed in our group of patients were the respiratory (100%), cardiovascular (100%), hepatic (73.9%) and renal dysfunction (65.2%). The ICU mortality of patients with 3 or less organ system dysfunctions was 11.7% (2/17) compared with 66.6% (4/6) for the group of patients with 4 or more organ system dysfunctions (P = 0.021). Multivariate analysis identified blood lactate levels (BLL) as the only variable independently associated with in-ICU death (OR = 2.59, 95%CI: 1.04-6.43, P = 0.040). ICU and hospital mortality rates were 26.1% and 43.5%, respectively. CONCLUSION: The mortality rate in critically ill patients with both HM, and AB infections who are admitted to the ICU is high. The variable most associated with increased mortality was

    Purpose Bariatric surgery is relatively new in Korea, and studies comparing different bariatric procedures in Koreans are lacking. This study aimed to compare the clinical outcomes of laparoscopic adjustable gastric banding (LAGB), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG) for treating morbidly obese Korean adults. Materials and Methods In this multicenter retrospective cohort study, we reviewed the medical records of 261 obese patients who underwent different bariatric procedures. Clinical outcomes were measured in terms of weight loss and resolution of comorbidities, such as diabetes, hypertension, and dyslipidemia. Safety profiles for the procedures were also evaluated. Results In terms of weight loss, the three procedures showed similar results at 18 months (weight loss in 52.1% for SG, 61.0% for LAGB, and 69.2% for RYGB). Remission of diabetes, hypertension, and dyslipidemia was more frequent in patients who underwent RYGB (65.9%, 63.6%, and 100% of patients, respectively). Safety profiles were similar among groups. Early complications occurred in 26 patients (9.9%) and late complications in 32 (12.3%). In the LAGB group, five bands (6.9%) were removed. Among all patients, one death (1/261=0.38%) occurred in the RYGB group due to aspiration pneumonia. Conclusion The three bariatric procedures were comparable in regards to weight-loss outcomes; nevertheless, RYGB showed a higher rate of comorbidity resolution. Bariatric surgery is effective and relatively safe; however, due to complications, some bands had to be removed in the LAGB group and a relatively high rate of reoperations was observed in the RYGB group.

    Chronic liver infection by hepatitis C virus (HCV) is a major public health concern. Despite partly successful treatment options, several aspects of intrahepatic HCV infection dynamics are still poorly understood, including the preferred mode of viral propagation, as well as the proportion of infected hepatocytes. Answers to these questions have important implications for the development of therapeutic interventions. In this study, we present methods to analyze the spatial distribution of infected hepatocytes obtained by single cell laser capture microdissection from liver biopsy samples of patients chronically infected with HCV. By characterizing the internal structure of clusters of infected cells, wemore » are able to evaluate hypotheses about intrahepatic infection dynamics. We found that individual clusters on biopsy samples range in size from 4-50 infected cells. In addition, the HCV RNA content in a cluster declines from the cell that presumably founded the cluster to cells at the maximal cluster extension. These observations support the idea that HCV infection in the liver is seeded randomly (e.g. from the blood) and then spreads locally.

    We illustrate 2 cases of pneumonia associated with Bordetella pertussis infection in 72-year-old and 61-year-old patients with cancer receiving myelosuppressive therapy after hematopoietic stem cell transplantation. Bacterial infections are a significant cause of morbidity and mortality in patients with cancer, and those receiving hematopoietic stem cell transplant, solid organ transplant, or myelosuppressive therapy are at increased risk. The infection was detected and the 2 patients had good outcomes following azithromycin treatment. Pertussis, also known as whooping cough, is a contagious respiratory illness that has become a public health challenge due to decreased immunity of the pertussis vaccine. Therefore, it is critical to recognize pertussis early in the course of the disease.

    Hepatitis B virus (HBV) infection continues to be a major public health problem worldwide. Although treatment indications are well established in clinical practice guidelines, there are some risk groups, such as pregnant women and immunosuppressed patients, who require different and specific management of HBV infection. In pregnant women, treatment indication should be individualized and the risk of HBV transmission to the newborn evaluated because cases of vertical transmission continue to be reported, despite active and passive immunoprophylaxis. In patients receiving immunosuppressive therapy, HBV reactivation is associated with high morbidity and mortality, even in patients with past HBV infection, highlighting the importance of screening and the need to evaluate prophylactic therapy in some cases.

    This review explores the extensive influence of viral infections leading to chronic deterioration of lung function in patients with cystic fibrosis (CF). The mechanisms how viral agents affect the pathogenesis as well as the inflammatory and immune response of CF are discussed. Viral infections of the upper and lower respiratory tract due to viruses in CF patients and methods for diagnosis of respiratory viruses are described in detail. The importance of respiratory and non-respiratory viral agents for the pathogenesis, especially for the exacerbation of bacterial lower respiratory tract infections and course of CF, is stressed, especially emphasizing respiratory syncytial virus, influenza virus, rhinovirus, and human herpes viruses. Possible harmful effects of further viruses like adenovirus, bocavirus, coronavirus, metapneumovirus, parainfluenzavirus on the lung function of CF patients are discussed. The potential use of adenovirus-based vectors for somatic gene therapy is mentioned. PMID:24688762

    2015-01-01

    Eosinophilia is not uncommonly encountered in patients infected with human immunodeficiency virus (HIV); particularly at initiation of care or among those with advanced disease. The clinical manifestation most commonly associated with eosinophilia in this patient population is skin rash. Management of these patients is challenging due to a paucity of data evaluating diagnostic testing and therapeutic strategies. Patients born in or with significant travel to parasite-endemic countries are more likely to have tissue-invasive helminthes, such as Strongyloides or Schistosoma. Patients without such risk factors are unlikely to have parasitic infections and frequently will have self-resolution of eosinophilia. When a detailed history, physical exam and diagnostic work-up is unrevealing, we sometimes consider empirical therapy with ivermectin. Praziquantel may also be considered for those at risk for schistosomiasis. PMID:26126686

    Purpose To report the incidence and clinical outcomes of non-cytomegalovirus (non-CMV) ocular opportunistic infections in patients with AIDS in the era of highly active antiretroviral therapy (HAART). Design Multicenter, prospective, observational study of patients with AIDS Methods Medical history, ophthalmologic examination, and laboratory tests were performed at enrollment and every 6 months subsequently. Once an ocular opportunistic infection was diagnosed, patients were seen every 3 months for outcomes. Results At enrollment, 37 non-CMV ocular opportunistic infections were diagnosed: 16 patients, herpetic retinitis; 11 patients, toxoplasmic retinitis; and 10 patients, choroiditis. During the follow-up period, the estimated incidences (and 95% confidence intervals [CI]) of these were: herpetic retinitis, 0.007/100 person-years (PY) (95% CI 0.0004, 0.039); toxoplasmic retinitis, 0.007/100 PY (95% CI 0.004, 0.039); and choroiditis 0.014/100 PY (95% CI 0.0025, 0.050). The mortality rates appeared higher among those patients with newly diagnosed or incident herpetic retinitis and choroiditis (rates=21.7 deaths/100 PY [P=0.02] and 12.8 deaths/100 PY [P=0.04]) respectively, than that for patients with AIDS without an ocular opportunistic infection (4.1 deaths/100 PY); Toxoplasmic retinitis did not appear to be associated with greater mortality (6.4/100 PY, P=0.47). Eyes with newly-diagnosed herpetic retinitis appeared to have a poor visual prognosis with high rates of visual impairment (37.9/100 PY) and blindness (17.5/100 PY), whereas those outcomes in eyes with choroiditis appeared to be lower (2.3/100 PY and 0/100 PY, respectively). Conclusions Although uncommon, non-CMV ocular opportunistic infections may be associated with high rates of visual loss and/or mortality. PMID:23068916

    2012-01-01

    Human herpesviruses may cause infections of the central nervous system during primary infection or following reactivation from a latent state. Especially in immunosuppressed patients the infection can take a life-threatening course, and therefore early diagnosis of herpesvirus-associated neurological diseases should have high priority. Clinical presentation in these patients is usually without typical features, making diagnosis even more challenging. Therefore general broad testing for different herpesviruses in cerebrospinal fluid samples is highly recommended. In addition, determination of the virus DNA level in the cerebrospinal fluid by quantitative assays seems to be of high importance to determine prognosis. Moreover, it might help to differentiate between specific virus-associated disease and unspecific presence of virus in the cerebrospinal fluid, especially in immunocompromised patients. Polymerase chain reaction analysis of cerebrospinal fluid has revolutionized the diagnosis of nervous system viral infections, particularly those caused by human herpesviruses. This review summarizes the role human herpesviruses play in central nervous system infections in immunocompromised patients, with a focus on the clinical manifestation of encephalitis. PMID:22973424

    Since there are limited data on the incidence and clinical findings of central nervous system (CNS) infection by three α-herpesviruses including human herpes simplex virus 1 (HSV-1), HSV-2 and varicella-zoster virus (VZV) in Korea, a retrospective analysis of clinical data and polymerase chain reaction (PCR) results was performed in patients who presented with suspicion of acute viral meningitis and/or encephalitis at the emergency department of a tertiary referral hospital in Seoul, Korea. During the 3-year study period, a total of 224 cerebrospinal fluid (CSF) samples from 224 patients were examined. Among the 224 patients, 135 (60.3%) patients were identified as having aseptic meningitis (n = 70, 51.9%), encephalitis (n = 41, 30.4%) or meningoencephalitis (n = 24, 17.8%) at discharge. Twenty-four (17.8%) patients were identified as having VZV meningitis (n = 16, 11.9%), VZV meningoencephalitis (n = 2, 1.5%), HSV-2 meningitis (n = 4, 3.0%), or HSV-1 encephalitis (n = 2, 1.5%). Of the 24 patients infected with the three herpesviruses, immunocompromised patients accounted for 33.3% (n = 8). Skin rashes were observed in half (n = 9) of the patients with VZV, and none with HSV-1 or HSV-2. One patient with VZV meningitis and four patients with brain parenchymal involvement had neurologic sequelae. In conclusion, three herpesviruses are important causative agents of CNS infectious disease with significant morbidity in adults, regardless of the immunologic status. Therefore, CSF should be examined for HSV-1, HSV-2, and VZV using sensitive diagnostic methods in all cases of adult patients with clinical manifestations of CNS disease in order to identify the correct etiology and to determine appropriate therapy.

    The year 2012 was the 50th anniversary of the Korean Neurosurgical Society, and in 2013, the 15th World Congress of Neurosurgery took place in Seoul, Korea. Thus, it is an appropriate occasion to introduce the world to the history of the Korean Neurosurgical Society and the foundation, development, and growth of Korean neurosurgery. Historical materials and pictures were collected and reviewed from the history book and photo albums of the Korean Neurosurgical Society. During the last 50 years, the Korean Neurosurgical Society and Korean neurosurgery have developed and grown enormously not only in quantity but also in quality. In every aspect, the turning point from the old to the new era of the Korean Neurosurgical Society and Korean neurosurgery was the year 1980.

    Bacterial infections are common but have become increasingly resistant to drugs. The aim of the present study was to examine the combined treatment of traditional Chinese and Western medicine in 30 cases of pulmonary infection with multidrug resistant Acinetobacter baumannii. Patients were divided into groups A and B according to drug treatments. Cefoperazone or sulbactam and tanreqing were administered in group A, and cefoperazone or sulbactam in group B. The curative effect and prognosis of the two groups were recorded and the remaining treatments were performed routinely in the clinic. For the combined therapy group, which was administered sulperazone and tanreqing, 8 patients were recovered, 6 patients had significant effects, 3 patients exhibited some improvement and 1 patient had no response. One of the patients did not survive after 28 days. By contrast, there were 4 patients that were successfully treated, 3 patients with significant effects, 2 patients with some improvement and 2 patients had no response in the sulperazone group, and 4 patients did not survive after 28 days. In conclusion, the combined therapy of cefoperazone or sulbactam supplemented with tanreqing was identified to be more effective than cefoperazone or sulbactam as monotherapy, for treating multidrug resistant Acinetobacter baumannii.

    Tinea capitis is generally thought to be a common disease in children but not in adults. When infection does occur in adults, it may have an atypical appearance. We report an elderly female with inflammatory tinea capitis caused by Trichophyton rubrum. She had numerous pustular lesions throughout the scalp with alopecia, initially treated for bacterial infection. We concluded that tinea capitis should remain in the differential diagnosis of elderly patients with alopecia and pyoderma like presentations and culture test should be routinely done in such patients to avoid complications.

    Background The Clinical Assessment Interview for Negative Symptoms (CAINS) is one of the validated interview measures of negative symptoms in psychotic disorders. The Motivation and Pleasure Scale-Self-Report (MPSR) is a self-report measure that assesses the motivation and pleasure domains of negative symptoms based on the CAINS. This study evaluated the reliability and validity of a Korean version of the MPSR. Methods A total of 139 patients with schizophrenia completed the MPSR, CAINS, Scale for the Assessment of Negative Symptoms (SANS), Brief Psychiatric Rating Scales, Calgary Depression Scale for Schizophrenia, and other measures of trait and cognitive function. Results The 15-item MPSR showed good internal consistency. In addition, it also had a good convergent validity with the Motivation and Pleasure subscale of the CAINS and the anhedonia/avolition subscale of the SANS. The scale was not associated with psychotic symptoms, agitation/mania, and depression/anxiety, and it showed good discriminant validity. MPSR scores were significantly correlated with Behavioral Activation System total score for trait measure. Conclusion The Korean version of the MPSR is a notable self-report method for examining the severity of negative symptoms in schizophrenia. PMID:27274251

    Objective The goal of this study was to assess the effect of high-dose simvastatin on cerebral vasospasm and its clinical outcome after aneurysmal subarachnoid hemorrhage (SAH) in Korean patients. Methods This study was designed as a prospective observational cohort study. Its subjects were aneurysmal SAH patients who had undergone aneurysm clipping or coiling. They were assigned to 1 of 3 groups : the 20 mg, 40 mg, and 80 mg simvastatin groups. The primary end-point was the occurrence of symptomatic vasospasm. The clinical outcome was assessed with the modified Rankin Scale (mRS) score after 1 month and 3 months. The risk factors of the development of vasospasm were assessed by logistic regression analysis. Results Ninety nine patients with aneurysmal SAH were treated and screened. They were sequentially assigned to the 20 mg (n=22), 40 mg (n=34), and 80 mg (n=31) simvastatin groups. Symptomatic vasospasm occurred in 36.4% of the 20 mg group, 8.8% of the 40 mg group, and 3.2% of the 80 mg group (p=0.003). The multiple logistic regression analysis showed that poor Hunt-Hess grades (OR=5.4 and 95% CI=1.09-26.62) and high-dose (80 mg) simvastatin (OR=0.09 and 95% CI=0.1-0.85) were independent factors of symptomatic vasospasm. The clinical outcomes did not show a significant difference among the three groups. Conclusion This study demonstrated that 80 mg simvastatin treatment was effective in preventing cerebral vasospasm after aneurysmal SAH, but did not improve the clinical outcome in Korean patients.

    In type 2 diabetic patients, the relationships between 25-hydroxyvitamin D and parathyroid hormone levels, and glycemic control, remain unclear. We evaluated associations between 25-hydroxyvitamin D, parathyroid hormone, and hemoglobin A1c levels after adjusting for other covariates, including log transformed 25-hydroxyvitamin D levels and log transformed parathyroid hormone levels, in Korean patients with type 2 diabetes. In total, 1,175 patients with type 2 diabetes were selected from 8,857 individuals who completed the baseline survey of the Dong-gu study, conducted in Korea from 2007 to 2010. After adjusting for other covariates, we found that the mean hemoglobin A1c level was inversely associated with the 25-hydroxyvitamin D level (Q1: 7.47% [7.30–7.63], Q2: 7.25% [7.09–7.40], Q3: 7.17% [7.02–7.32], Q4: 7.19% [7.02–7.35]; p for trend = 0.021, p for between groups = 0.050) and the parathyroid hormone level (Q1: 7.35% [7.19–7.51], Q2: 7.34% [7.19–7.50], Q3: 7.28% [7.13–7.43], Q4: 7.09% [6.94–7.24]; p for trend = 0.022, p for between groups = 0.048). However, the mean fasting glucose level was not associated with either the 25-hydroxyvitamin D or parathyroid hormone level. In conclusion, inverse associations were evident between hemoglobin A1c, 25-hydroxyvitamin D and parathyroid hormone levels in Korean patients with type 2 diabetes. The associations remained significant after adjusting for other covariates, including the log transformed 25-hydroxyvitamin D levels and log transformed parathyroid hormone levels. PMID:27362844

    Objective Osteoarthritis (OA) of the temporomandibular joint (TMJ) is generally thought to be an age-related disease like those of other joints. This study aims to investigate the incidence of computed tomographic (CT) OA changes in Korean temporomandibular disorder (TMD) patients diagnosed by the Research Diagnostic Criteria for TMD (RDC/TMD). Materials and methods The clinical records and radiographs of 1038 TMD patients (297 men and 741 women with mean age 31.1 ± 17.4 and 34.0 ± 16.2, respectively) diagnosed based on RDC/TMD Axis I in 2010 were reviewed. Results The incidence rate of OA changes in TMD patients is estimated to 27.3%, and higher in women than in men (15.5% in men and 32.0% in women) by 2.3 odds (p < 0.001). It has no correlation with age, showing an almost flat incidence rate throughout the age from the 2nd decade and has no correlation as well with pain or disc displacement diagnosed according to RDC/TMD, while arthrosis/arthritis diagnosis based on RDC/TMD supplemented by plain radiographs shows high risk of OA changes on CT by 38.8 odds (p < 0.05). Conclusions These results imply that the OA changes in young Korean TMD patients are as common as in the old and have no correlation with clinical pain and noise. Considered with high prevalence of TMDs known in the young population, the overall/absolute OA changes in the TMJ can be even higher in the young than in the old population, not like in other joints.

    This study evaluated the ultrasound (US) features of 20 patients with MAGI and concomitant papilloma virus (HPV) infection compared to 20 patients with microbial (presence of Chlamydia trachomatis alone) MAGI and 20 patients with amicrobial (inflammatory) MAGI. Patients with HPV infection showed significantly (p < 0.05) higher total prostate, seminal vesicles, and epididymal US signs (18.0 ± 2.0) compared to the other 2 groups (12.0 ± 4.0 versus 10.0 ± 3.0, resp.). In addition, patients with MAGI and HPV had a higher prevalence of complicated forms of MAGI [prostatovesiculitis (PV) and prostate-vesiculo-epididymitis (PVE)] and a higher frequency of the fibrosclerotic variant compared to the other groups (70.0 ± 10.0% versus 48.0 ± 5.0% versus 15.0 ± 10.0%). Moreover, HPV infected patients had a higher number of US criteria suggestive for MAGI in the periurethral region of the prostate compared to the other groups. In particular, the patients showed a higher ratio between periurethral and lobar US criteria distribution (5.0 versus 0.5). Finally, the seminal fluid concentration of CD45pos leukocytes (2.0 ± 0.2 versus 1.3 ± 0.3 versus 1.0 ± 0.3 mil/mL) was significantly higher and sperm progressive motility was significantly lower in these patients compared to other groups.

    The present study aimed to evaluate the molecular epidemiology of HBV in chronic HBV infected cases from northeast India (NEI), since scanty data are available from the region which has a predominant ethnically distinct tribal population. A total of 523 clinically diagnosed index chronic HBV infected cases and 172 asymptomatic patients (based on family screening) were enrolled with informed consent. Patients were stratified based on serology, imaging, pathology, and clinical data and grouped as chronic HBV and cirrhotic cohorts. Analysis for serum HBV DNA levels and HBV genotyping was performed, and was statistically co-related with disease severity. Males were more prone to chronic HBV infection. Majority of the patients who had Chronic HBV infection based on family screening were females (59.88%), majorly wives of index patients. Mean viral load in Chronic HBV patients was almost 4.5-folds higher than cirrhosis patients, and was significantly associated with e-antigen positive status(P < 0.001) in both groups. HBV genotype D was the most prevalent genotype (62.30%) in NEI. Mixed genotype infection of A + D was found from Assam, along with C + D cases (1.29%) cumulatively. There is a high prevalence of HBV genotype C (13.96%) in our studied cohort which was found to be associated with higher viral load(P = 0.018), e-antigen positivity(P = 0.043), and increased cirrhosis risk compared to Chronic HBV cases [OR = 1.670]. Family contacts in NEI are prone to infection with HBV and development of Chronic HBV. Higher presence of e-positive cases and genotype C along with the mixed genotypes in NEI is unique and of significance with reference to predisposition to disease severity and even response to antiviral therapy.

    AIM: To describe the frequency of H pylori infection among 1000 southern Iranian dyspeptic patients. METHODS: A prospective study was performed in a referral hospital in south of Iran from 1999 to 2005. One thousand dyspeptic patients (518 males, mean ± SD age of 49.12 ± 12.82 years) consecutively underwent upper gastrointestinal endoscopy. Multiple gastric antral biopsy samples were taken from all patients for rapid urease test and histopathologic examination (96.9% satisfactory samples). Patients were considered H pylori-infected if one or both tests were positive. RESULTS: Six hundred and seventy-one patients (67.1%, 95% confidence interval [CI]: 64.2%-70.0%) were H pylori-infected. H pylori positivity was significantly more frequent in patients with peptic ulcer disease (PUD) than in those with non-ulcer dyspepsia (P < 0.001). Male-to-female ratio for duodenal and gastric ulcers was 2.7:1 and 1.5:1, respectively. Moreover, the duodenal-to-gastric ulcer ratio was 1.95:1. The frequency of H pylori infection among those with endoscopic diagnosis of gastritis, duodenal ulcer, gastric ulcer, and normal mucosa was 70.1% (398/568), 86.2% (150/174), 71.9% (64/89), and 33.5% (54/161), respectively. H pylori infection, male sex, and older age were independently associated with PUD in multivariate analysis. H pylori positivity was associated with chronic gastritis, and chronic active gastritis with odds ratios of 34.21 (95% CI: 12.19%-96.03%) and 81.21 (95% CI: 28.85%-228.55%), respectively. CONCLUSION: H pylori and PUD are highly frequent in dyspeptic patients from south of Iran. H pylori is a cardinal risk factor for chronic active or inactive gastritis. PMID:17006984

    Invasive pulmonary aspergillosis is a life-threatening mycosis that only affects patients with immunosuppression, chemotherapy-induced neutropenia, transplantation, or congenital immunodeficiency. We studied the clinical, genetic, histological, and immunological features of 2 unrelated patients without known immunodeficiency who developed extrapulmonary invasive aspergillosis at the ages of 8 and 18. One patient died at age 12 with progressive intra-abdominal aspergillosis. The other patient had presented with intra-abdominal candidiasis at age 9, and developed central nervous system aspergillosis at age 18 and intra-abdominal aspergillosis at age 25. Neither patient developed Aspergillus infection of the lungs. One patient had homozygous M1I CARD9 (caspase recruitment domain family member 9) mutation, while the other had homozygous Q295X CARD9 mutation; both patients lacked CARD9 protein expression. The patients had normal monocyte and Th17 cell numbers in peripheral blood, but their mononuclear cells exhibited impaired production of proinflammatory cytokines upon fungus-specific stimulation. Neutrophil phagocytosis, killing, and oxidative burst against Aspergillus fumigatus were intact, but neither patient accumulated neutrophils in infected tissue despite normal neutrophil numbers in peripheral blood. The neutrophil tissue accumulation defect was not caused by defective neutrophil-intrinsic chemotaxis, indicating that production of neutrophil chemoattractants in extrapulmonary tissue is impaired in CARD9 deficiency. Taken together, our results show that CARD9 deficiency is the first known inherited or acquired condition that predisposes to extrapulmonary Aspergillus infection with sparing of the lungs, associated with impaired neutrophil recruitment to the site of infection.

  12. Clinical and Genetic Features of Korean Patients with Recurrent Fever and Multi-System Inflammation without Infectious or Autoimmune Evidence

    PubMed Central

    2016-01-01

    Autoinflammatory disease (AID) is a newly proposed category of disorders characterized by unprovoked episodes of inflammation without any infectious or autoimmune evidence. We aimed to characterize the clinical and genetic features of patients who had recurrent fever and multi-system inflammation but remain unclassified for any established AIDs. Medical records of 1,777 patients who visited our Rheumatology Clinic between March 2009 and December 2010 were reviewed to identify those who met the following criteria; 1) presence of fever, 2) inflammation in two or more organ systems, 3) recurrent nature of fever or inflammation, 4) no evidence of infection or malignancy, 5) absence of high titer autoantibodies, and 6) failure to satisfy any classification criteria for known AIDs. Genotyping was performed for common missense variants in MEFV, NOD2/CARD15, and TNFRSF1A. A small number of patients (17/1,777, 0.95%) were identified to meet the above criteria. Muco-cutaneous and musculoskeletal features were most common, but there was a considerable heterogeneity in symptom combination. Although they did not satisfy any established classification criteria for AIDs, substantial overlap was observed between the clinical spectrum of these patients and known AIDs. According to the newly proposed Eurofever criteria for periodic fevers, eleven of them were classified as TNF receptor-associated periodic syndrome and two as mevalonate kinase deficiency. However, no examined genetic variants including those in TNFRSF1A were found in these patients. A new set of classification criteria needs to be developed and validated for Asian patients with unclassified AIDs. PMID:26839472

    Context: Hepatitis-C virus (HCV) infection and diabetes mellitus (DM) have a significant association with skin disorders. Aims: The aim of this study was to assess the impact of HCV infection on the pattern of cutaneous infections among diabetic patients. Methods and Material: A prospective study included diabetic patients who attended Al-Hussein University hospital, Cairo during the period from 2008 to 2010. Patients were examined for skin infections, and investigated for HCV infection. Statistical Analysis Used: SPSS (version 11.5). Results: The study included 163 patients (102 males and 61 females) with a mean age of 46.2 ± 4.83 years. Ninety five patients (58.3%) were HCV+ve (group A) while 68 patients (41.8%) were HCV-ve (group B). Skin infections in group A included fungal (48.4%), viral (26.3%), bacterial (22.1%) and parasitic (3.2%) while in group B, the spectrum included bacterial (41.2%), fungal (39.7%), viral (11.7%) and parasitic (7.4%). Onychomycosis was the commonest infection in group A (25.2%) compared with folliculitis in group B (19.1%). Cutaneous infections in HCV+ patients were more characterized by increased severity, aggressive course, resistance to treatment and rapid relapse. Conclusions: HCV infection has a significant impact in increasing and changing the spectrum of skin infections in diabetic patients. Severe and resistant infections in diabetics could be an important sign of HCV infection. PMID:24891654

  14. Cardiovascular risk and dyslipidemia management in HIV-infected patients.

    2012-01-01

    HIV infection and antiretroviral therapy each appear to increase cardiovascular disease risk. Increased risk may be attributable to the inflammatory effects of HIV infection and dyslipidemia associated with some antiretroviral agents. The prevalence of cardiovascular disease is increasing as patients live longer, age, and acquire traditional coronary heart disease (CHD) risk factors. In general, any additional cardiovascular risk posed by HIV infection or antiretroviral therapy is of potential concern for patients who are already at moderate or high risk for CHD. Long-term and well-designed studies are needed to more accurately ascertain to what degree HIV infection and antiretroviral therapy affect long-term cardiovascular disease risk. Management of dyslipidemia to reduce CHD risk in HIV-infected patients is much the same as in the general population, with the cornerstone consisting of statin therapy and lifestyle interventions. Smoking cessation is a major step in reducing CHD risk in those who smoke. This article summarizes a presentation by James H. Stein, MD, at the IAS-USA live continuing medical education activity held in New York City in March 2012.

    Bartonella henselae is a bacterium which can cause a wide range of clinical manifestations, ranging from fever of unknown origin to a potentially fatal endocarditis. We report a case of Bartonella henselae infection in a pediatric-aged patient following a scratch from a kitten. The patient initially presented with a prolonged fever of unknown origin which was unresponsive to antibiotic treatment. The patient was hospitalized with worsening fevers and night sweat. Subsequent ultrasound imaging demonstrated multiple hypoechoic foci within the spleen. A contrast-enhanced CT of the abdomen and pelvis was also obtained which showed hypoattenuating lesions in the spleen and bilateral kidneys. Bartonella henselae IgG and IgM titers were positive, consistent with an acute Bartonella henselae infection. The patient was discharged with a course of oral rifampin and trimethoprim-sulfamethoxazole, and all symptoms had resolved following two weeks of therapy. PMID:27127672

    The prevalence of invasive mycoses is increasing, especially among patients who are immunocompromised or hospitalized with serious underlying diseases. Such infections are associated with a high morbidity and significant mortality, requiring early diagnosis and appropriate treatment but also an optimal prophylaxis in patients with high risk factors. We report a case of triple fungal infection including an invasive pulmonary aspergillosis by Aspergillus fumigatus, a candidemia by Candida albicans and a Pneumocystis pneumonia. The overall clinical picture of this patient was liver cirrhosis with medical history of immunosuppressive treatment for Crohn disease and a non-hodgkin lymphoma. There was no antifungal prophylaxis for this patient. Under treatment, the issue was unfavourable with multivisceral failure.

    Background Although liver transplantation has been widely practised, post-operative bacterial infection is still a frequent complication which contributed to an increased risk of fatality. There were studies on preoperative use of probiotics for liver transplant patients and acquired reduction in postoperative sepsis and wound infection, but the relevant clinical experience with pre- and probiotics is still limited. Objectives This study is to assess fibre and probiotic use aimed at preventing bacterial sepsis and wound complications in patients undergoing liver transplantation. Study methods There were a total of sixty-seven adult patients scheduled for liver transplantation were included in a public teaching hospital. From January to December 2011, 34 continuous patients following liver transplantation were put on fibre + probiotics. In retrospectively, from January to December 2010, 33 continuous patients were collected as a control group and they were only received fibre post operation. The incidence of bacterial infections was compared in patients receiving either fibre and lactobacillus or fibre only. Statistical analysis was performed using SPSS 15. The t test, fisher’s and chi- square test was used to compare discrete variables. Results In summary, in the analysis of 67 liver transplant recipients, 8.8% group A patients developed infections compared to 30.3% group B patients. The difference between groups A and B was statistically significant in both cases. In addition, the duration of antibiotic therapy was significantly shorter in the lactobacillus-group. Wound infection was the most frequent infections and enterococci the most frequently isolated bacteria. Fibre and lactobacilli were well tolerated in most cases. The operating time, amount of intra- and post-operatively transfused units of blood, fresh frozen plasma and albumin did not differ significantly between the groups. Conclusions Combined fibre and probiotics could lower the incidence of

    Since the 1960s, regular hemodialysis (HD) was recognized as a risk factor for the development of infective endocarditis (IE), particularly at vascular access sites. The present report describes our experience at the Etat Major General Agadir, Morocco, of taking care of IE in patients on regular dialysis. A retrospective analysis was made of five cases of IE in patients receiving regular HD having arteriovenous fistula as vascular access. They were sent from four private centers and admitted in our formation between January 2004 and March 2009. Infective endocarditis was detected after 34.5 months following initiation of dialysis. The causative organisms included Staphylococcus and Enterococcus in two cases each and negative blood culture in one case. A recent history of infection (<3 months) of the vascular access was found in three cases. Peripheric embolic phenomena were noted in two cases. A pre-existing heart disease was common and contributed to heart failure. Mortality was frequent due to valvular perforations and congestive heart failure, making the medical treatment alone unsatisfactory. Two patients survived and three of our patients received a prosthetic valve replacement, with a median survival after surgery of 10.3 months/person. The clinical diagnosis of infective endocarditis in regularly dialyzed patients remains difficult, with the presence of vascular calcification as a common risk factor. The vascular catheter infections are the cardinal gateway of pathogenic organisms, which are mainly Staphylococcus. The prognosis is bad and the mortality is significant, whereas medical and surgical treatments are often established in these patients who have many factors of comorbidity. PMID:21196639

    Hepatitis E virus is responsible for sporadic cases of acute, self-limited viral hepatitis not only in endemic but also in industrialized countries. In addition, some reports confirm that it can cause chronic infection and even cirrhosis in immunosuppressed and also in patients infected with HIV. There are few data about prevalence and incidence of HEV chronic infection in HIV-HEV coinfected individuals in Spain. The aim of this study is to investigate the prevalence of anti-HEV IgG in a representative sample of 448 patients infected with HIV and determine the role of age, gender, and CD4 counts in the detection of anti-HEV IgG antibodies in blood. In addition, the clinical features and ALT levels in relation to the presence of anti-HEV IgM and/or HEV-RNA in the blood of these patients were investigated. Anti-HEV IgG antibodies were detected in serum using a commercial enzyme immunoassay. All positive samples were studied further for the presence of anti-HEV IgM antibodies. In addition, HEV RNA was amplified by reverse transcriptase (RT)-nested PCR in all serum samples with IgM anti-HEV. The overall prevalence of anti-HEV IgG was 10.4% (45/448, 95% C.I. 7.2-12.8%). HEV-RNA was found in only one patient out of the 45 anti-HEV IgG positive samples studied. Regarding to gender and CD4 count, no difference in seroprevalence could be observed. This prevalence data suggest that patients infected with HIV can be considered a risk group for HEV infection and that chronic coinfection HEV-HIV seems to be a very rare event. PMID:24136591

    Recently, the taxonomy of Ochroconis (Ascomycota, Pezizomycotina, Venturiales, Sympoventuriaceae) has been revised with the recognition of an additional genus, Verruconis. Ochroconis comprises mesophilic saprobes that occasionally infect vertebrates which mostly are cold-blooded, while Verruconis contains thermophilic species which is a neurotrope in humans and birds. On the basis of molecular data it is noted that only a single Ochroconis species regularly infects immunocompetent human hosts. Here we report a subcutaneous infection due to Ochroconis mirabilis in a 50-year-old immunocompetent female patient. In vitro antifungal susceptibility tests revealed that terbinafine was the most effective drug. The patient was successfully cured with oral administration of terbinafine 250 mg daily in combination with 3 times of topical ALA-photodynamic therapy for 9 months. PMID:27182484

    Chlamydia is a sexually transmitted disease of epidemic proportions, infecting an estimated 4 million people a year. It results not only in infertility and ectopic pregnancy but also in infant morbidity and mortality. Ectopic pregnancy is responsible for 11 percent of maternal deaths. About 60 percent of infected women can transmit the bacteria at birth to their infants. Early detection and treatment of chlamydia in both men and women, especially prenatal women, is critical. Chlamydia trachomatis infection of the cervix was found in 8.1 percent of a group of 1,004 pregnant women at a hospital prenatal clinic by means of a direct fluorescent antibody test. The prevalence of C. trachomatis was only 0.7 percent in 277 pregnant women receiving prenatal care from private practitioners. All patients between 27 and 30 weeks gestation who tested positive were treated with oral erythromycin. Their partners were treated with tetracycline. The outcome of pregnancy in patients treated for chlamydial infection was compared with a control group of noninfected mothers from the same population. The frequency of premature rupture of the membranes, prematurity, and low Apgar scores among the treated women were not significantly different from those in the control group. There was a significant difference, however, between the two groups in the incidence of low mean birth weight infants and the presence of meconium. Children can acquire a chlamydial infection at birth from contact with infected cervico-vaginal secretions. If not detected and treated, these infected infants may develop conjunctivitis, bronchiolitis, and pneumonia. It is suggested, therefore, that all patients at prenatal clinics be screened for chlamydial cervicitis.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1910182

    Universal infantile hepatitis B virus (HBV) vaccination may lead to an increase in vaccine escape variants, which may pose a threat to the long-term success of massive vaccination. To determine the prevalence of occult infections in Korean vaccinated individuals, 87 vaccinated subjects were screened for the presence of HBV DNA using both the nested PCR protocol and the VERSANT HBV DNA 3.0 assay. The mutation patterns of variants were analyzed in full-length HBV genome sequences. Their HBsAg secretion and replication capacities were investigated using both in vitro transient transfection and in vivo hydrodynamic injection. The presence of HBV DNA was confirmed in 6 subjects (6.9%). All six variants had a common mutation type (X8Del) composed of an 8-bp deletion in the C-terminal region of the HBV X gene (HBxAg). Our in vitro and in vivo analyses using the full-length HBV genome indicated that the X8Del HBxAg variant reduced the secretion of HBsAg and HBV virions compared to the wild type. In conclusion, our data suggest that a novel mutation (X8Del) may contribute to occult HBV infection in Korean vaccinated individuals via a reduced secretion of HBsAg and virions, possibly by compromising HBxAg's transacting capacity.

    Background The ratio of the diameter of the main pulmonary artery (mPA) to the diameter of the aorta (Ao) on chest computed tomography is associated with diverse clinical conditions. Herein, we determined the functional and prognostic implications of the mPA/Ao ratio in Korean chronic obstructive pulmonary disease (COPD) patients. Methods The study population comprised 226 chronic obstructive pulmonary disease patients from the Korean Obstructive Lung Disease cohort who underwent chest computed tomography. We analyzed the relationships between the clinical characteristics, including pulmonary function, echocardiography findings, St. George's Respiratory Questionnaire, 6-minute walking (6MW) distance, and exacerbation with the mPA, Ao, and mPA/Ao ratio. Results The mean age was 65.8 years, and 219 (96.9%) patients were male. The mean FEV1% predicted and FEV1/FVC ratio were 61.2% and 47.3%, respectively. The mean mPA and Ao were 23.7 and 36.4 mm, respectively, and the mPA/Ao ratio was 0.66. The mPA/Ao ratio correlated negatively with the 6MW distance (G = -0.133, P = 0.025) and positively with the right ventricular pressure (G = 0.323, P = 0.001). After adjustment for potential confounders, the mPA/Ao ratio was significantly associated with 6MW distance (β = -107.7, P = 0.017). Moreover, an mPA/Ao ratio >0.8 was a significant predictor of exacerbation at the 1-year (odds ratio 2.12, 95% confidence interval 1.27–3.52) and 3-year follow-ups (odds ratio 2.04, 95% confidence interval 1.42–2.90). Conclusions The mPA/Ao ratio is an independent predictor of exercise capacity and an mPA/Ao ratio >0.8 is a significant risk factor of COPD exacerbation. PMID:27152915

  6. Correction options for lipoatrophy in HIV-infected patients.

    Engelhard, Peter

    2006-03-01

    Lipoatrophy (LA) is a form of lipodystrophy, characterized by volume depletion caused by fat loss in the limbs, buttocks, and face. Facial volume loss is the most obvious outward sign of LA because it alters the facial contours in the cheeks, temples, and orbits. Lipodystrophy and LA are most commonly seen in patients with HIV on highly active antiretroviral therapy (HAART), which was introduced in the mid-1990s for the management of HIV, and is currently considered the mainstay therapy for HIV-infected patients. However, the etiology of LA is likely multifactorial as underlying patient conditions, including duration and severity of HIV and increasing age, have also been found to contribute to its occurrence. The volume loss of LA can be very dramatic with some patients exhibiting no signs of facial fat. As a result, many HIV-infected patients with associated LA suffer from psychological and lifestyle effects, which can lead to noncompliance with HAART. Thus, increases in facial volume and improvement in morphology is anticipated to reduce anxiety caused by LA in HIV-infected patients, and improve quality of life. This review discusses the benefits and limitations of several treatment options available to correct the volume depletion associated with LA, including antiretroviral switching, permanent surgical implants and injectables, poly-L-lactic acid, collagen, and hyaluronic acid derivatives.

    This study aims to assess the incidence rate of Pteropine orthreovirus (PRV) infection in patients with acute upper respiratory tract infection (URTI) in a suburban setting in Malaysia, where bats are known to be present in the neighborhood. Using molecular detection of PRVs directly from oropharyngeal swabs, our study demonstrates that PRV is among one of the common causative agents of acute URTI with cough and sore throat as the commonest presenting clinical features. Phylogenetic analysis on partial major outer and inner capsid proteins shows that these PRV strains are closely related to Melaka and Kampar viruses previously isolated in Malaysia. Further study is required to determine the public health significance of PRV infection in Southeast Asia, especially in cases where co-infection with other pathogens may potentially lead to different clinical outcomes.

    Poor perineal wound healing and infections after proctectomy surgery cause a significant proportion of physical and psychological morbidities, such as pain, leakage, and abscesses. In the long run, some of these symptoms will lead to extended periods of hospitalization. These kinds of postoperative complications are also associated with delays in possible chemotherapy treatment. The aim of this study was to describe patient experiences of perineal wound infections following proctectomy due to rectal cancer, and the importance of the communication with and the self-care support from the nurse for these patients. Five women and five men (61-87 years, median age 71 years) were included and interviewed. A qualitative content analysis of the interviews was carried out and the following main categories emerged: "Managing postoperative complications," "Being independent," "Feeling safe," and "Accepting the situation." A perineal wound infection after a proctectomy is devastating for the individual patient. The limitations and changes to the patients' lives turn into new daily routines, which force them to find new ways to live and to accept the situation. For many of them, the infections remained for several months and, sometimes, for years. The ability to lead an independent life is drastically reduced, but through continuity in care it is possible to create a feeling of safety. Information, communication, and self-care support are all important and valuable factors for recovery. Specialized care containing an action plan is therefore needed in clinical practice to reduce the number of perineal wound infections postoperatively and should be initiated when the patient is discharged from the ward and continue until recovery.

    Objective This study reports the clinical characteristics and outcome of HIV-associated Penicilliummarneffei infection in northern Vietnam. Methods We conducted a retrospective chart review of all patients with laboratory confirmed Penicilliummarneffei infection admitted to the National Hospital for Tropical Diseases in Hanoi, Vietnam, between July 2006 and September 2009. Results 127 patients with P. marneffei infection were identified. All were HIV-infected; median CD4+ T-cell count was 24 cells/μl (IQR:12-48); 76% were men. Common clinical features were fever (92.9%), skin lesions (82.6%), hepatomegaly (61.4%), lymphadenopathy (40.2%), weight loss (59.1%) and cough (49.6%). Concurrent opportunistic infections were present in 22.0%; half of those had tuberculosis. Initial treatment regimens were: itraconazole or ketoconazole capsule (77.2%), amphotericin B (20.5%), and fluconazole (1.6%). In-hospital mortality was 12.6% and showed no significant difference in patients treated with itraconazole (or ketoconazole) and amphotericin B (p = 0.43). Dyspnea, ascites, and increased LDH level were independent predictors of mortality. No seasonality was observed. Conclusion The clinical features, treatments and outcomes of HIV-associated P. marneffei infection in northern Vietnam are similar to those reported in other endemic regions. Dyspnea was an important predictor of mortality. More patients were treated with itraconazole than amphotericin B and no significant difference in treatment outcome was observed. It would be of clinical value to compare the efficacy of oral itraconazole and amphotericin B in a clinical trial. PMID:22897817

    Objective: Prophylactic antibiotics significantly reduce prosthetic joint infection (PJI) rates after hip and knee arthroplasty. However, the rise of antibiotic resistance has raised concern over the adequacy of conventional prophylaxis. This study aimed to identify organisms causing early PJI in hip and knee arthroplasties and their sensitivity to current prophylactic antibiotics. Method: We performed a multicentre audit of 4009 primary hip and knee arthroplasties (1852 hips and 2157 knees) at three tertiary referral hospitals. PJIs were identified according to the Infectious Diseases Society of America (IDSA) definition and all patients were followed for two years. For patients with confirmed PJIs, causative bacteria and their antibiotic sensitivities were identified. Results: Thirty-five PJI cases in total were identified in the follow-up period of two years, consisting of 13 hips and 22 knees. The overall definite prosthetic joint infection rate was 0.87% (0.7% for hips, 1.0% for knees). 51.4% of PJIs occurred within the first 6 weeks, 62.9% within the first 3 months and 82.9% during the first year. Ninety-six percent (96%) of patients were given cefazolin as prophylaxis. Thirty-four percent (34%) of patients were infected with Coagulase-negative staphylococci, which were the most common infective organisms. 91.7% of these organisms were resistant to cefazolin. Twenty-five percent (25%) of patients were infected with Staphylococcus aureus, 9.1% of which were methicillin resistant. Overall, 58% of organisms were resistant to cefazolin. Sixty percent (60%) of patients who were treated with cefazolin and had available sensitivities for infective organism(s) were infected with cefazolin-resistant organisms. Conclusions: The majority of bacteria causing early PJI are resistant to the antibiotic prophylaxis given at the time of surgery. Whilst all the organisms cultured were sensitive to vancomycin, concerns regarding antibiotic stewardship remain and there is

    Immunomodulatory antibodies that enhance the immune system to fight cancer are revolutionizing the treatment of patients with an expanding variety of malignancies. There is a unique spectrum of side effects associated with immunomodulatory antibodies, termed immune-related adverse events (irAEs), which include colitis and hepatitis among others. The treatment of refractory or severe irAEs can occasionally require significant immunosuppression, involving steroids or tumor necrosis factor-alpha antagonists, placing these patients at risk for infections. We present the first reported case to our knowledge of an opportunistic infection in a patient treated with an immunomodulatory antibody. As the use of immunomodulatory antibodies expands and more patients develop irAEs that require treatment with immunosuppression, recognition of the potential for opportunistic infections in this emerging patient population will be critical. Prospective trials are needed to define the optimal immunosuppressive management of irAEs and determine whether prophylactic antiviral, antibacterial, or antifungal therapies are beneficial in this unique population.

    In order to provide safe and secure medical care for patients, health care-associated infections (HAI) must not occur. HAI should be considered as incidents, and countermeasures should be viewed as a patient safety management itself. Healthcare-associated infection control (HAIC) is practiced by the infection control team (ICT), which is based on multidisciplinary cooperation. Team members have to recognize that it is the most important to make use of the expertise of each discipline. In addition, all members must try to respond quickly, to help the clinic staff. Visualized rapid information provision and sharing, environmental improvement, outbreak factor analysis, hand hygiene compliance rate improvement, proper antibiotic use (Antimicrobial Stewardship Program: ASP), and regional cooperation & leadership comprise the role of the ICT in the flagship hospital. Regarding this role, we present our hospital's efforts and the outcomes. In conclusion, for medical practice quality improvement, healthcare-associated infection control should be conducted thoroughly along with an awareness of patient safety. PMID:27363228

    The magnitude of intestinal parasitic infection in acquired immunodeficiency syndrome patients requires careful consideration in the developing world where poor nutrition is associated with poor hygiene and several tropical diseases. However, there have been very few studies addressing this issue in Cameroon. This study was conducted to determine the prevalence of intestinal parasitosis in HIV/AIDS patients in Dschang -Cameroon. Stool and blood specimens from HIV/AIDS patients and control group were screened respectively for intestinal parasites and for HIV antibodies. Intestinal parasites were identified using direct microscopy, formalin-ether concentration and Ziehl Neelsen methods. Out of 396 participants recruited among patients consulting at hospital, 42 (10.6%) were HIV positive, thirty of them treatment naïve. The overall prevalence of intestinal parasites was 14.64%. Out of 42 HIV/AIDS patients, 59.5% (25/42) were infected with intestinal parasites, while only 9.32% (33/354) of the HIV negative patients were infected with intestinal parasites. The parasites detected in our study population included Crystosporidium parvum (2.53%), Entamoeba histolytica (7.52%), Entamoeba coli (4.04%), Giardia lamblia (0.25%), Trichuris trichura (0.25%), Strongyloides stercoralis (0.25%) and Taenia spp. (0.25%). In the HIV infected group, Crystosporidium parvum (19.04%), Entamoeba histolytica (19.04%), Entamoeba coli (21.42%), Giardia lamblia (2.38%), Strongyloides stercoralis (0.25%) and Taenia spp. (0.25%) were found. Crystosporidium parvum was found to be significantly higher in HIV/AIDS patients than in controls (P<0.05). Multivariate analysis showed that the HIV status and the quality of water were the major risk factors for intestinal parasitosis. Routine examinations of stool samples for parasites would significantly benefit the HIV patients by contributing in reducing morbidity and improving the efficiency of antiretroviral treatment.

    Abstract Currently, limited data are available regarding the efficacy and safety of pegylated interferon alpha-2a (PEG-IFN α-2a) in Korean patients with chronic hepatitis B (CHB), in whom hepatitis B virus (HBV) genotype C is the most common type. We collected data from 439 patients (HBeAg positive, n = 349; HBeAg negative, n = 90) with CHB who were treated with PEG-IFN α-2a as a first-line therapy from 18 institutions. Treatment responses at the end of treatment (ET) and at 6 months posttreatment (PT6) were compared between the patients who were treated for 24 weeks versus 48 weeks, and adverse events (AEs) were evaluated. In HBeAg-positive patients, those who received PEG-IFN α-2a for 48 weeks showed significantly higher HBV DNA suppression (HBV DNA < 2000 IU/mL) than those who were treated for 24 weeks (48 weeks vs 24 weeks; at ET, 44.4% vs 36.7%, P = 0.035; at PT6, 35.9% vs 13.3%, P = 0.035). The HBeAg seroconversion rate at ET was 18.1% in 48-week treatment group, which is significantly higher than the 2.2% (P < 0.001) that was seen in 24-week treatment group. This finding also continued at PT6 (29.0% vs 10.0%, P < 0.001). Following 48 weeks of treatment in HBeAg-negative patients, HBV DNA suppression at ET was higher than in HBeAg-positive patients (87.8% vs 44.4%). AEs were typical of those associated with PEG-IFN α-2a. In naïve Korean HBeAg-positive CHB patients treated with PEG-IFN α-2a, higher rates of HBV DNA suppression and HBeAg seroconversion were achieved in the 48-week treatment group than in the 24-week treatment group without additional risk of AEs.

    Background Leptin is an adipokine with complex metabolic, neuroendocrine and immune functions. Our objective was to evaluate leptin serum levels in a cohort of Romanian HIV-infected patients undergoing antiretroviral therapy in relation to their immune-virological status, lipid and glucose metabolic abnormalities and the presence of metabolic syndrome (MS). Methods We enrolled consecutive non-diabetic HIV-infected patients aged 18 and over on stable cART for at least 6 months. Blood samples were tested for: leptin, CD4 T cells count, HIV viral load and lipid panel. Results A total of 90 HIV-infected patients were included in the study: 50 males (55.6%) with a mean age of 33.3 years and 40 females with a mean age of 30.4 years. Most patients (74.4%) had HIV viral load below the limit of detection and the median CD4 count for the cohort was 476 (410) cells/cmm. More than one third of the patients (41.1%) had hypoleptinemia. The prevalence of MS was 13.3%. Hypoleptinemia was significantly more frequent in men. In a subset of patients with undetectable HIV viral load, the median leptin value was 0.6 (6.07) ng/mL in patients with poor immune recovery (CD4 count ≤ 200/cmm) compared to 2 (3.07) ng/mL for those with better immune response (CD4 count > 200/cmm), without statistical significance. The median values of leptin were similar for persons with and without MS criteria. HDL-cholesterol values were positively correlated to leptin values in a linear regression model. Conclusion A significant proportion of patients in our study presented low levels of leptin; this finding was not associated with immune and virological parameters or the presence of MS. Hypoleptinemia was significantly correlated with lower levels of HDL-cholesterol, a key cardiovascular risk factor. PMID:26405677

    Background Molecular techniques can often reveal a broader range of pathogens in respiratory infections. We aim to investigate the prevalence and age pattern of viral co-infection in children hospitalized with lower tract acute respiratory infection (LT-ARI), using molecular techniques. Methods A nested polymerase chain reaction approach was used to detect Influenza (A, B), metapneumovirus, respiratory syncytial virus (RSV), parainfluenza (1–4), rhinovirus, adenovirus (A—F), bocavirus and coronaviruses (NL63, 229E, OC43) in respiratory samples of children with acute respiratory infection prospectively admitted to any of the GENDRES network hospitals between 2011–2013. The results were corroborated in an independent cohort collected in the UK. Results A total of 204 and 97 nasopharyngeal samples were collected in the GENDRES and UK cohorts, respectively. In both cohorts, RSV was the most frequent pathogen (52.9% and 36.1% of the cohorts, respectively). Co-infection with multiple viruses was found in 92 samples (45.1%) and 29 samples (29.9%), respectively; this was most frequent in the 12–24 months age group. The most frequently observed co-infection patterns were RSV—Rhinovirus (23 patients, 11.3%, GENDRES cohort) and RSV—bocavirus / bocavirus—influenza (5 patients, 5.2%, UK cohort). Conclusion The presence of more than one virus in pediatric patients admitted to hospital with LT-ARI is very frequent and seems to peak at 12–24 months of age. The clinical significance of these findings is unclear but should warrant further analysis. PMID:26332375

    Retinoids, a family of molecules capable of profound impact on many biological functions, have antiproliferative, differentiative, and immunomodulatory properties. The present study assessed the effect of 13-cis-retinoic acid (13-CRA) treatment in 13 chronic cervicitis and 52 cervical intraepithelial neoplasia patients. We examined low- and high-risk human papilloma virus titer (using the hybrid capture method) and made a colposcopic and cervicographic examination before and after treatment with 13-CRA at 1 mg/kg for 4 to 12 weeks. Patients were between 27 and 64 years, the average age being 36.6 years. Histology revealed chronic cervicitis in 13 cases, mild dysplasia in 18 cases, moderate dysplasia in 18 cases, and severe dysplasia in 16 cases, totaling 65 cases. The expression rate of high-risk human papilloma virus (HPV 16, 18) was 9 of 13 cases (69%) in chronic cervicitis, 7 of 18 cases (38%) in mild dysplasia, 9 of 18 cases (50%) in moderate dysplasia, and 12 of 16 cases (75%) in severe dysplasia, with the overall expression rate being 37 of 65 cases (57%). Following 13-CRA treatment, decreases in high-risk titer were observed in 6 of 9 cases (66%) of chronic cervicitis, 4 of 11 cases (36%) of mild dysplasia, 7 of 9 cases (77%) of moderate dysplasia, and 8 of 12 cases (75%) of severe dysplasia. Overall, HPV titer decreased in 25 of 41 cases (61%). Minimal changes were found in colposcopic and cervicographic observations during the study. In summary, high-risk HPV titer decreased after treatment with 13-CRA in the majority of patients with cervical intraepithelial neoplasia. This study supports the potential of retinoids to interrupt multi-step carcinogenesis, possibly by down-regulation of gene products (E6,E7) produced by HPV infection.

    2015-01-01

    Human nocardiosis, caused by Nocardia spp., an ubiquitous soil-borne bacteria, is a rare granulomatous disease close related to immune dysfunctions. Clinically can occur as an acute life-threatening disease, with lung, brain and skin being commonly affected. The infection was classically diagnosed in HIV infected persons, organ transplanted recipients and long term corticosteroid treated patients. Currently the widespread use of immunomodulators and immunossupressors in the treatment of inflammatory diseases changed this scenario. Our purpose is to review all published cases of nocardiosis in immunomodulated patients due to inflammatory diseases and describe clinical and laboratory findings. We reviewed the literature concerning human cases of nocardiosis published between 1980 and 2014 in peer reviewed journals. Eleven cases of nocardiosis associated with anti-tumor necrosis factor (TNF) prescription (9 related with infliximab and 2 with adalimumab) were identified; 7 patients had inflammatory bowel disease (IBD), 4 had rheumatological conditions; nocardia infection presented as cutaneous involvement in 3 patients, lung disease in 4 patients, hepatic in one and disseminated disease in 3 patients. From the 10 cases described in IBD patients 7 were associated with anti-TNF and 3 with steroids and azathioprine. In conclusion, nocardiosis requires high levels of clinical suspicion and experience of laboratory staff, in order to establish a timely diagnosis and by doing so avoid worst outcomes. Treatment for long periods tailored by the susceptibility of the isolated species whenever possible is essential. The safety of restarting immunomodulators or anti-TNF after the disease or the value of prophylaxis with cotrimoxazole is still debated. PMID:26074688

    9 months after immigration into Switzerland, a 38-year-old male patient from Liberia/West Africa developed granulomatous and subsequently ulcerative nodules in the face. The heterosexual patient, with no history of i.v. drug abuse, tested positive for HIV-2. Histology of a skin biopsy revealed superficial colonization by numerous fungal elements described as spores and hyphae that were compatible with the initial isolation of Candida parapsilosis. The definite diagnosis of African histoplasmosis was established 3 weeks later after review of the PAS-stained direct smear and after cultures had grown a cream-colored mold subsequently identified as Histoplasma capsulatum var. duboisii. There were no signs of disseminated disease. The lesions cleared under therapy with itraconazole (200 mg q 24h for 2 weeks, subsequently 100 mg q 24h) as well as ketoconazole and Aqua Dalibour (A. zinco-cuprica) locally for 2 months. Follow-up was not possible. Despite alarmingly increasing numbers of HIV-positive patients in Africa, the general incidence of African histoplasmosis seems to be stable with only a few cases per year. To our knowledge only four cases of disseminated African histoplasmosis have been reported in HIV-positive patients; localized cutaneous infection as in our patient, seems to be the exception. The low incidence of this infection is in contrast to the substantial number of HIV-positive patients with disseminated histoplasmosis by H. capsulatum var. capsulatum in the United States.

HCV genotype, viral load, abdominal ultrasonographic findings, and HCV-specific cell-mediated immunity (CMI) were examined among 141 healthcare workers infected with HCV (68 workers with and 73 workers without S. mansoni). HCV genotype 4 was dominate, and viral loads were 2.62 ± 0.69 × 106 and 4.24 ± 1.4 × 106 IU/mL among patients with and without coinfection, respectively (P = 0.309); 23.5% with and 32.9% without coinfection had spontaneously resolved HCV infection (P = 0.297). Interferon-γ spot-forming cells/106 peripheral blood mononuclear cells among responding viremic patients with and without coinfection were 716 ± 194 and 587 ± 162, whereas among aviremic patients, it was 794 ± 272 and 365 ± 36 (P > 0.05), respectively. In conclusion, there was no statistical difference in HCV spontaneous resolution, viral load, liver pathology, or CMI in patients with or without S. mansoni coinfection, suggesting that it did not impact the outcome of HCV infection.

    Appropriate screening for HIV infection is the cornerstone of HIV-related care. There have been several recent changes in testing technology and screening recommendations. The US Preventive Services Task Force recommends universal HIV screening at least once for adolescents and adults ages 15 to 65 years, and additional screening for patients at higher risk, although evidence is insufficient to determine optimum rescreening intervals. All pregnant women should be screened for HIV infection in the first trimester, and pregnant women at high risk should be screened again in the third trimester. The Centers for Disease Control and Prevention recommends use of an algorithm using fourth-generation tests for screening; this decreases the window period between infection and detection to as few as 14 days, thereby reducing the number of false-negative results. Home HIV testing kits, which require follow-up confirmatory testing, also are available. Clinicians should be aware of HIV-specific laws in their states, including those criminalizing HIV exposure and transmission. Thorough medical and laboratory evaluations are essential at initiation of care for patients with HIV infection, along with appropriate follow-up monitoring, as recommended in various guidelines.

    The first kidney transplantation was performed in 1951 and ever since then living donor transplantation became a more and more important solution for patients with end-stage renal disease (ESRD). Renal transplantation is a life-saving procedure. Morbidity and mortality on waiting-lists are strongly correlated with the time of dialysis and end-stage renal disease is one of the most important causes of death; this is the reason why transplantation has to be performed as soon as possible in order to reduce the time of dialysis. Once the transplantation is performed, a number of complications may occur in post-transplant evolution, the most important of which is rejection. The rejection may appear through several mechanisms, but one of the most frequent causes of rejection is cytomegalovirus (CMV) infection. It is very important to have a precocious and fast diagnosis of CMV infection in order to maintain the functionality and survival of the graft. PP65 CMV antigenemia has proven its effectiveness in detecting and monitoring the CMV infection in transplanted patients. In the laboratory of the Clinical Institute of Urology and Renal Transplantation (ICUTR) of Cluj Napoca the CMV infection is evidenced by two methods: PP65antigenemia and IgM antibody identification by chemiluminiscence.

    We report the first Korean case of lung diseases caused by Mycobacterium abscessus subsp. bolletii in a previously healthy male, except for a previous history of pulmonary tuberculosis and bronchiectasis. All serial isolates are identified as M. abscessus subsp. bolletii by multi-locus sequence analysis based on the hsp65, rpoB, and 16S rRNA fragments. At the genetic level, the isolate has the erm(41) gene with a T28 sequevar, associated with clarithromycin resistance, and no rrl mutation. The isolate is resistant to clarithromycin. Although the symptoms and radiographic findings have improved after combination of antibiotics, the follow-up sputum cultures are persistently positive. PMID:24523815

    A 59-year-old woman suffering from chronic lymphocytic leukemia developed pulmonary lesions; bronchoalveolar lavage was performed for possible systemic fungal infection. However, direct microscopic analysis revealed ciliated protozoa identified as Balantidium coli. B. coli is the only known pathogenic ciliate, and is usually associated with intestinal infection in areas associated with pig rearing. On very rare occasions the organisms may invade extra-intestinal organs, in this case the lungs of an immunocompromised patient. This case is unusual as balantidiasis is rare in Europe, the patient had no obvious contact with pigs, and there was no history of diarrhea prior to pulmonary colonization. Metronidazole was rapidly administered, and the condition improved after 24-48 hr. PMID:12827655

    The incidence of hospital-acquired infections varies between 2 and 15% (on average 5 to 8%). Most common nosocomial infections are urinary tract infections, wound infections, respiratory tract infections, septicemia and infections of the skin and subcutaneous tissue. Nosocomial infections arise essentially via two routes: endogenously from the bodies own flora or exogenously via direct or indirect contact with the patient. Bacteria are most commonly transmitted from patient to patient by hands. Air as a vehicle, by which bacteria are transmitted, plays a relatively minor role. Priorities in hospital infection control are: hand washing and hand desinfection, improvement of certain nursing techniques, isolation of infected or susceptible patients, an infection control team with a nurse epidemiologist, surveillance and control of antibiotic therapy regimens, especially of antibiotic prophylaxis. Routine floor desinfection could not be shown to significantly reduce the hospital infection rate.

    Although infective endocarditis (IE) is relatively uncommon, it remains an important clinical entity with a high in-hospital and 1-year mortality. It is most commonly caused by viridans streptococci. Staphylococcus aureus is responsible for a malignant course of IE and often requires early surgery to eradicate. Other rarer causes are various bacilli, including the HACEK (Haemophilus, Actinobacillus,Cardiobacterium, Eikenella and Kingella spp.) group of organisms and fungi. The clinical presentation varies. Patients may present with a nonspecific illness, valve dysfunction, heart failure (HF) and symptoms due to peripheral embolisation. The diagnosis is traditionally based on the modified Duke criteria and rests mainly on clinical features and to a lesser extent on certain laboratory findings,microbiological assessment and cardiovascular imaging. Identification of the offending micro-organism is not only important from a diagnostic point of view, but also makes targeted antibiotic treatment possible and provides useful prognostic information. A significant proportion of microbiological cultures are negative, frequently owing to the administration of antibiotics prior to appropriate culture.Blood-culture-negative IE poses significant diagnostic and treatment challenges. The course of the disease is frequently complicated, and sequelae include HF, local intracardiac extension of infection (abscess, fistula, pseudoaneurysm), stroke and intracranial haemorrhage due to septic emboli or mycotic aneurysm formation as well as renal injury. Management includes prolonged intravenous antibiotics and consideration for early surgery with removal of infective tissue and valve replacement in patients who have poor prognostic features or complications. Antibiotic administration for at-risk patients to prevent bacteraemia during specific procedures (particularly dental) is recommended to prevent IE.

    Mees' lines, or transverse striate leukonychia, are classically associated with arsenic poisoning, but have been described in other cases of acute or chronic illness. Their pathogenesis is thought to be a disruption of nail plate keratinization secondary to systemic stress. Mees' lines are observed in a patient with helminthic and amebic infections and no history of arsenic exposure. This case demonstrates another clinical setting in which Mees' lines can appear, providing further evidence that Mees' lines may chronicle systemic disease.

Even if the diagnosis of an IgA deficiency has normally no specific therapeutic consequences, it is important to identify this disorder because it is associated with a higher incidence of allergic reaction during treatment with blood products and can also evolve into a common variable immunodeficiency.

    2014-06-01

    Survival has improved in patients with cystic fibrosis (CF), in part because of aggressive antimicrobial management. Two multidrug-resistant environmental bacteria, the Burkholderia cepacia group and nontuberculous mycobacteria, have emerged. Improving genomic and proteomic technologies are allowing better identification of bacteria and fungi found in the CF lung and detection of viral agents that may be associated with pulmonary exacerbations. Anaerobic bacteria and Streptococcus angionsus group organisms may play a role in chronic CF lung infections. The diversity of organisms declines perhaps as a result of aggressive antimicrobial therapy, and an apex predator, Pseudomonas aeruginosa, may emerge in many patients with CF.

    Stress has significant adverse impacts on health outcomes of HIV-infected patients. Our study explored coping with stress strategies by HIV-infected Iranian patients. A qualitative content analysis study was conducted at the Consultation Clinic of HIV at the Imam Khomeini Hospital in Tehran, Iran in 2012. Twenty-six semi-structured in-depth interviews were done. Participants were asked about coping strategies for stress. After the first interview, continuous analysis of data was started and continued up to data saturation. Results showed that participants used two categories of strategies (emotion-based coping and problem-based coping) to cope with stress. Emotion-based coping had two sub-themes: adaptive and maladaptive. The problem-based coping category had three sub-themes: participation in education sessions, adherence to medication, and efforts to maintain a healthy lifestyle. Explanations of different strategies available to HIV-infected patients to cope with stress may help develop tailored interventions to improve the psychological conditions of people living with HIV.

    The patient, a 30-year-old housewife, visited a nearby doctor in mid August 2002 because of weight loss and neck swelling. HIV tests done at the hospital were positive. She was referred to and admitted to our hospital on October 2 for detailed examination and treatment of the neck tumor. A coat of epithelial debris extended from the oral cavity to the pharynx and an abscess and a fistula were found in the left tonsil. After hospitalization, an abscess culture revealed the presence of acid-fast bacteria, which was identified as Mycobacterium peregrinum. Treatment with imipenem and clarithromycin resulted in the normalization of CRP (0.1 mg/dl), on day 5 of treatment. The patient was discharged from the hospital after treatment for 2 weeks with imipenem and clarithromycin. Thereafter, the patient received continuous treatment with faropenem and clarithromycin for 4 more weeks, and has shown no signs of recurrence for 11 months to date. Only a few cases of infection with this bacterial strain have been reported. This infection is difficult to treat because most antituberculosis agents are not effective against it and there is limited availability of effective antibiotics. Medical treatment of infection caused by Mycobacterium peregrinum may be useful in such cases. PMID:15805720

    A wide variety of disorders of diverse pathogenic mechanisms can trigger spinal cord dysfunction in HIV-1-infected patients. The most common such condition is HIV-1-associated myelopathy (HM) which characteristically complicates advanced HIV-1 disease in patients with low CD4 cell counts and previous AIDS-defining diagnoses. We describe an unusual presentation of HM in a previously asymptomatic patient with a relatively preserved CD4 cell count (458 cells/mm3) who was even unaware of his serological status. The patient presented with a clinically severe, slowly progressive myelopathy and could not walk unassisted. Significant neurological improvement could be obtained as rapidly as within 4 weeks after the institution of an antiretroviral combination of only two nucleoside analog HIV-1 reverse transcriptase inhibitors (zidovudine and didanosine). An HIV-1 protease inhibitor was also prescribed at that point but could only be added to intensify the regimen 3 months later, when significant neurological improvement had already been recorded. We also review the disorders reported to derange spinal cord function in previously asymptomatic HIV-1-infected patients.

    The optimal antiretroviral therapy (ART) regimen for human immunodeficiency virus (HIV)–infected patients with cancer remains unknown, as clinical trials are lacking and published data are insufficient to guide recommendations. When concomitant use of chemotherapy and ART is anticipated, overlap of toxic effects and drug–drug interactions between chemotherapy and ART may alter the optimal choice of ART. Prospective studies are urgently needed to further define the toxic effects of combined chemotherapy and ART in HIV-positive cancer patients. Such studies should aid the development of guidelines for treatment of this population. For now, clinicians should individualize decisions regarding treatment of HIV according to clinical and laboratory findings, cancer treatment plan (chemotherapy, radiotherapy, or surgery), liver or renal disease, potential adverse drug effects (eg, rash, gastrointestinal intolerance, bone marrow suppression), and patient preference. This review focuses on what infectious disease specialists need to know to select the most appropriate ART regimens for patients receiving chemotherapy. PMID:24642555

    Systematic studies have shown that gram-positive organisms are the leading cause of invasive bacterial disease in patients with cancer. A broad range of gram-positive bacteria cause serious infections in the cancer patient with the greatest burden of disease being due to staphylococci, streptococci, and enterococci. The evolution of cancer therapy and the changing epidemiology of major gram-positive pathogens mean that ongoing efforts are needed to understand and mitigate the impact of these bacteria in patients with malignancy. The development of novel antibacterials, optimization of treatment approaches, implementation of improved vaccines, and manipulation of the microbiome are all active areas of investigation in the goal of improving the survival of the cancer patient through amelioration of the disease burden of gram-positive bacteria.

    The systemic host response to microbial infection involves clinical signs and symptoms of infection, including fever and elevated white blood cell (WBC) counts. In addition, inflammatory mediators are released, including activated complement product C3a, interleukin 6 (IL-6), and the acute-phase reactant secretory phospholipase A(2) (sPLA(2)). To compare the value of the latter with the former in predicting (the degree of) microbial infection at the bedside, we determined clinical variables and took blood samples daily for 3 consecutive days in 300 patients with a new fever (>38.0 degrees C rectally or >38.3 degrees C axillary). Microbiological culture results for 7 days after inclusion were collected. Patients were divided into clinical and microbial categories: those without and with a clinical focus of infection and those with negative cultures, with positive local cultures or specific stains for fungal (n = 13) or tuberculous infections (n = 1), and with positive blood cultures, including one patient with malaria parasitemia. The area under the curve (AUC) of the receiver operating characteristic (ROC) for prediction of positive cultures was 0.60 (P < 0.005) for peak temperature and 0.59 (P < 0.01) for peak WBC count, 0.60 (P < 0.005) for peak C3a, 0.63 (P < 0.001) for peak IL-6, and 0.61 (P < 0.001) for peak sPLA(2). The AUC under the ROC curve for prediction of positive blood cultures was 0.68 (P < 0.001) for peak temperature and 0.56 for peak WBC count (P < 0.05). The AUC for peak C3a was 0.69, that for peak IL-6 was 0.70, and that for sPLA(2) was 0.67 (for all, P < 0.001). The degree of microbial invasion is thus a major determinant of the clinical and inflammatory host response in patients with fever. Moreover, circulating inflammatory mediators such as C3a and IL-6 may help to predict positive blood cultures, together with clinical signs and symptoms of the host response to microbial infection, even before culture results are available. This may help in

    Purpose The benefit–risk balance for drugs can alter post approval owing to additional data on efficacy or adverse events. This study developed a quantitative benefit–risk assessment (BRA) model for statins using multicriteria decision analysis with discrete choice experiments and compared a recent BRA with that at the time of approval. Patients and methods Following a systematic review of the literature, the benefit criteria within the statin BRA model were defined as a reduction in the plasma low-density lipoprotein cholesterol level and a reduction in myocardial infarction incidence; the risk criteria were hepatotoxicity (Liv) and fatal rhabdomyolysis (Rha). The scores for these criteria were estimated using mixed treatment comparison methods. Weighting was calculated from a discrete choice experiment involving 203 Korean patients. The scores and weights were integrated to produce an overall value representing the benefit–risk balance, and sensitivity analyses were conducted. Results In this BRA model, low-density lipoprotein (relative importance [RI]: 37.50%) was found to be a more important benefit criterion than myocardial infarction (RI: 35.43%), and Liv (RI: 16.28%) was a more important risk criterion than Rha (RI: 10.79%). Patients preferred atorvastatin, and the preference ranking of cerivastatin and simvastatin was switched post approval because of the emergence of additional risk information related to cerivastatin. Conclusion A quantitative statin BRA model confirmed that the preference ranking of statins changed post approval because of the identification of additional benefits or risks. PMID:27358567

[Subjects] The subjects were 30 patients with acute stroke. [Methods] The subjects were randomly assigned to either the experimental group (EG) or the control group (CG). The EG subjects received CBCR with the CoTras program. The CG subjects received conventional cognitive rehabilitation. All subjects participated in a standard rehabilitation program according to a daily inpatient treatment schedule. In addition to standard rehabilitation, the subjects received 20 sessions (5 days a week for 4 weeks) of CBCR or conventional cognitive rehabilitation for 30 min. To compare the two groups, the Lowenstein Occupational Therapy Cognitive Assessment (LOTCA) and Motor-free Visual Perception Test-3 (MVPT-3) were performed. [Results] Both groups showed significant improvement in LOTCA and MVPT-3. Furthermore, there were significant differences in LOTCA and MVPT-3 between the two groups. [Conclusion] CBCR with CoTras may contribute toward the recovery of cognitive function and visual perception in patients with acute stroke.

    The risk of herpes zoster among patients with juvenile idiopathic arthritis (JIA) exposed to biologics has not been evaluated. We determined incidence rates of herpes zoster among children with JIA in correlation with medication at time of occurrence and total drug exposure. The German biologics register database was used to identify patients with herpes zoster. Crude infection rates and incidence ratios (IRR) were compared to published rates. Demographics and overall exposure and particular exposure time to corticosteroids, immunosuppressive drugs and biologics were analyzed. The JIA cohort included 3,042 patients with 5,557.9 person-years of follow-up; 1,628 have used corticosteroids, 2,930 methotrexate and 1,685 etanercept. In total, 17 herpes zoster events have been documented [6/1,000 patients (3.5-9.0); 3.1/1,000 patient-years (1.9-4.9)]. Thus, the incidence rate in JIA patients was higher than expected [IRR 2.9 (1.8-4.5), p < 0.001]. In all patients, the event resolved completely. There were two complications, one patient developed intercostal neuralgia, and one had a recurrent herpes zoster. Compared to the healthy population, a significant higher IRR is observed in JIA patients who received a monotherapy with etanercept or in combination with steroids and methotrexate, but not in JIA patients exposed to methotrexate without biologics. In comparison with our control group of patients treated with methotrexate, the IRR was higher for exposure to etanercept monotherapy and combination of etanercept and corticosteroids irrespective of methotrexate use. A generally higher incidence rate in JIA patients treated with etanercept was observed. No serious or refractory manifestations occurred.

    Lower respiratory tract infections (LRTIs) are one of the most frequent medical conditions seen in out-patients. They all cause morbidity, and although most are minor some may be life-threatening, thus appropriate disease management is important. Clinical features are usually used to classify LRTIs, but this approach may be inaccurate. It may therefore be simpler to describe a patient's symptoms without applying a label, such as "bronchitis", since the latter means different things to different people. Classification of LRTIs should aim to aid management. The two main management decisions are: whether to manage the patient at home; and whether to prescribe antibiotics. Investigations are carried out in the hospital environment to aid these decisions, however in the community investigation in only a minority of cases are done as they are costly and impractical. Markers of severity of LRTI have been identified in a number of studies and their value in clinical practice is now being assessed, however most studies suggest that severely ill patients are correctly identified and admitted to hospital. Currently, antibiotics are used liberally for lower respiratory tract infections. However most infections are not bacterial in origin and will not be affected by such therapy. The idea that antibiotics are harmless placebos for such illnesses is no longer tenable since the appearance and rapid spread of antibiotic resistance in bacteria. Only in community-acquired pneumonia and some patients with exacerbations of chronic bronchitis do antibiotics actually alter the course of the illness. In those groups antibiotics should be targetted at the casual pathogens and in other groups such therapy should be avoided. Much current research interest is focused on determining which (if any) is the best antibiotic in these situations. PMID:9510671

    Liver disease associated with hepatitis C virus (HCV) is a significant and increasing cause of death for HIV-infected patients, but limited data exist to guide treatment of coinfection. Increased knowledge of HCV disease and its treatment among HIV care practitioners and adoption of routine care procedures can improve management of coinfected patients. This article discusses HCV screening and diagnosis, counseling and health care maintenance, and evaluation for and supervision of treatment in HIV-seropositive patients who are coinfected with HCV. The experiences of the Oakland, California-based Alameda County Medical Center, which treats more than 200 coinfected patients, are detailed and serve as the basis for suggested management strategies.

    The emergence of direct-acting antiviral (DAA) agents has revolutionized the treatment schema for hepatitis C virus (HCV) infection. From cure rates to tolerability, DAA agents have shown outstanding profiles compared with the prior therapy of pegylated interferon with ribavirin. However, the efficacy and safety profiles of DAA therapy in older patients, particularly the elderly, have been unclear, and patients in the 1945 to 1965 birth cohort constitute the largest proportion of the HCV population in the United States. Treating elderly patients with pegylated interferon and ribavirin has been challenging due to the frequent presence of multiple comorbidities in the elderly and high discontinuation rates caused by adverse events. Now, as more DAA agents have become widely studied and approved, subgroup analyses for the elderly population are being elucidated. Analysis of the current literature shows that these agents have been effective, well tolerated, and safe in the elderly population. This article highlights the efficacy and safety differences in interferon-based therapy and interferon-free regimens for elderly patients with HCV infection. PMID:27482173

    Background Compared with coronary computed tomographic angiography (CCTA), the coronary artery calcium score (CACS) may be limited in predicting adverse cardiovascular events in asymptomatic diabetic patients. Methods We evaluated the predictive value of CACS for obstructive coronary plaques (OCPs) assessed by CCTA in 328 consecutive asymptomatic patients with type 2 diabetes mellitus who had an estimated glomerular filtration rate greater than 60 ml/min/1.73 m2. Results In total, 29 (9%) patients had OCPs: calcified or mixed OCPs and noncalcified OCPs were found in 26 (8%) and three (1%) patients, respectively. On the basis of a CACS of 0, 1–10, 11–100, and greater than 100, OCPs were found in 2, 5, 15, and 36% of patients, respectively. On receiver operating characteristic curve analysis, the optimal cutoff CACS for predicting OCPs was found to be 33, with 83% sensitivity and 81% specificity (area under the curve, 0.853; 95% confidence interval, 0.777–0.930; P<0.001). Positive and negative predictive values of a CACS of 33 for OCPs were 30 and 98%, respectively. On multivariate logistic regression analysis, age [odds ratio (OR), 1.09], microalbuminuria (OR, 3.43), current smoking (OR, 3.93), and CACS greater than 33 (OR, 15.85) were found to be independently associated with an increased risk for OCPs (P<0.05, respectively). The predictive significance of CACS greater than 33 for OCPs improved after considering the status of microalbuminuria and current smoking. Conclusion These findings suggest that CACS is an effective gatekeeper for evaluating obstructive coronary artery disease using CCTA in asymptomatic Korean patients with type 2 diabetes mellitus who have near-normal kidney function.

    The HIV epidemic has huge dimensions: in 2009, 33.3million people worldwide, including 2.5million children, were affected by human immunodeficiency virus (HIV) infection. The introduction of Highly Active Anti-Retroviral Therapy (HAART) has significantly modified the course of HIV disease, with longer survival and improved quality of life, but it has simultaneously lead to the appearance of previously unrecognized complications, such as ischemic cardiovascular events. Many studies have shown a higher rate of premature atherosclerosis in patients with HIV infection, leading to coronary, cerebrovascular, or peripheral arterial disease. However, it is still debated whether cardiovascular complications are a consequence of HIV infection itself or of the long-term use of HAART. In particular, myocardial infarction has been suggested to be associated with the use of abacavir. Endothelial dysfunction and platelet activation are markers of atherosclerosis and of increased cardiovascular risk. Here we review the evidence that endothelial dysfunction and platelet alterations are associated with chronic HIV infection, the possible role of different HAARTs, and the possible pathophysiologic mechanisms. Potential therapeutic implications are also discussed.

    Abstract Background Helminth infections are highly prevalent in tropical and subtropical countries, coexisting in Chagas disease endemic areas. Helminth infections in humans may modulate the host immune system, changing the Th1/Th2 polarization. This immunological disturbance could modify the immune response to other infections. The aim of this study is to evaluate the relationship between clinical, microbiological and epidemiological characteristics of Chagas disease patients, with the presence of helminth infection. Methods A prospective observational study was conducted at Vall d’Hebron University Hospital (Barcelona, Spain). Inclusion criteria were: age over 18 years, diagnosis of Chagas disease, and not having received specific treatment for Chagas disease previously to the inclusion. The study protocol included Chagas disease assessment (cardiac and digestive evaluation, detection of T. cruzi DNA measured by PCR in peripheral blood), and helminth infection diagnosis (detection of IgG anti-Strongyloides stercoralis by ELISA, microscopic examination of stool samples from three different days, and specific faecal culture for S. stercoralis larvae). Results Overall, 65 patients were included, median age was 38 years, 75.4% were women and most of them came from Bolivia. Cardiac and digestive involvement was present in 18.5% and 27.7% of patients respectively. T. cruzi PCR was positive in 28 (43.1%) patients. Helminth infection was diagnosed in 12 (18.5%) patients. No differences were observed in clinical and epidemiological characteristics between patients with and without helminth infection. Nevertheless, the proportion of patients with positive T. cruzi PCR was higher among patients with helminth infection compared with patients without helminth infection (75% vs 35.8%, p = 0.021). Conclusions We observed a high prevalence of S. stercoralis infection among chronic Chagas disease patients attended in our tropical medicine unit. Strongyloidiasis was associated

    A large body of evidence indicates that HIV-infected patients, both men and women, as well as adults and children, have a higher risk of developing arteriosclerotic cardiovascular disease. This evidence comes from studies whose main primary variables were the clinical manifestations of arteriosclerotic cardiovascular disease (acute myocardial infarction, silent myocardial ischemia, stroke and peripheral arterial disease) and the distinct markers of premature atherosclerosis and endothelial dysfunction determined in different sites (carotid, coronary or peripheral arteries) and with distinct diagnostic procedures (carotid intimamedia thickening, coronary artery calcification, flow-mediated vasodilation, arterial rigidity, ankle/arm index, etc.). This excess risk of arteriosclerotic cardiovascular disease in HIV-positive patients is clearly associated with the HIV infection per se and with classical cardiovascular risk factors, and, to a lesser extent and less uniformly, with the use of first-generation protease inhibitors. Hypertension, whose association with HIV infection is far less clear, is related to both traditional cardiovascular risk factors and to lipodystrophy.

    Abstract Background: Risk factors for catheter-associated urinary tract infections (CAUTIs) in patients undergoing non-cardiac surgical procedures have been well documented. However, the variables associated with CAUTIs in the cardiac surgical population have not been clearly defined. Therefore, the purpose of this study was to investigate risk factors associated with CAUTIs in patients undergoing cardiac procedures. Methods: All patients undergoing cardiac surgery at a single institution from 2006 through 2012 (4,883 patients) were reviewed. Patients with U.S. Centers for Disease Control (CDC) criteria for CAUTI were identified from the hospital's Quality Assessment database. Pre-operative, operative, and post-operative patient factors were evaluated. Univariate and multivariable analyses were used to identify significant correlations between perioperative characteristics and CAUTIs. Results: There were 55 (1.1%) documented CAUTIs in the study population. On univariate analysis, older age, female gender, diabetes mellitus, cardiogenic shock, urgent or emergent operation, packed red blood cell (PRBC) units transfused, and intensive care unit length of stay (ICU LOS) were all significantly associated with CAUTI [p<0.05]. On multivariable logistic regression, older age, female gender, diabetes mellitus, and ICU LOS remained significantly associated with CAUTI. Additionally, there was a significant association between CAUTI and 30-d mortality on univariate analysis. However, when controlling for common predictors of operative mortality on multivariable analysis, CAUTI was no longer associated with mortality. Conclusions: There are several identifiable risk factors for CAUTI in patients undergoing cardiac procedures. CAUTI is not independently associated with increased mortality, but it does serve as a marker of sicker patients more likely to die from other comorbidities or complications. Therefore, awareness of the high-risk nature of these patients should lead to

    BACKGROUND: Acute infective conjunctivitis is a self-limiting condition that commonly presents to primary care. Patients' understanding of conjunctivitis, their reasons for attendance, and their responses to different management strategies, are unknown. AIM: To explore patients' understanding of conjunctivitis and its management. DESIGN OF STUDY: Qualitative study using semi-structured one-to-one interviews. SETTING: Three general practices in Hampshire and Wiltshire. METHOD: Twenty-five patients presenting with conjunctivitis at their general practices were interviewed. Main outcome measures were patients' perceptions of conjunctivities, their experience and knowledge of the disease, beliefs regarding treatment, and their responses to different management strategies and a patient information leaflet. RESULTS: Patients regarded conjunctivitis as a minor illness, although some considered it might become more serious if not treated. Nearly all were confident at recognising conjunctivitis. They stated a preference for not taking medication, but believed that conjunctivitis would not clear up without treatment. However, they were open to alternative management approaches; for example, the delayed prescription approach, because they trusted their general practitioners' (GPs') judgement. Once they were aware of the self-limiting nature of conjunctivitis, patients felt they would prefer to wait a few days to see if the condition improved before seeking medical advice, even if this resulted in a few more days of symptoms. CONCLUSION: Patients who attend their general practices with conjunctivitis present for treatment because they are not aware of its self-limiting nature. Providing patients with this information may enable patients, enhance self-management, and reduce the use of topical antibiotics and the demand for urgent general practice appointments.

    ABSTRACT Despite ACIP recommendation and cost-effectiveness established in those 19–59 y old diabetes patients the uptake of Hepatitis B vaccine in diabetes patients is low. There is need to highlight the impact of Hepatitis B virus (HBV) infection in diabetes patients in terms of healthcare utilization and costs to recognize the burden of HBV in this population. This retrospective claims analysis included patients with diabetes and HBV (cases; n=1,236) and those with diabetes without HBV (controls; n=4,944), identified by ICD-9-CM diagnosis codes. Cases were matched with 4 controls using propensity score matching. Healthcare utilization and cost were compared; incremental effect of HBV infection was assessed using multivariate analysis. In the adjusted analyses, the mean number of hospitalizations (0.6 vs 0.4), outpatient service visits (34.2 vs. 20.4), and office visits (10.9 vs. 9.8) were 41%, 68%, and 11% higher, respectively, in cases vs. controls (all p<0.05). Gastroenterologist visits (0.8 vs. 0.2) and infectious disease visits (0.1 vs. 0.0) were 80% and 18% higher in subset of case and controls with these events. Cases ($39,435) incurred $16,397 incremental total costs compared with controls ($23,038). Medical ($30,968 vs. $17,765) and pharmacy costs ($8,029 vs. $5,114) were both significantly higher for cases (p < 0.0001). Healthcare utilization and costs were higher among patients with diabetes and HBV than in those with diabetes alone. These results provide evidence supporting the need for HBV vaccination among unvaccinated diabetes patients. PMID:27050021

    Due to their shared transmission route, hepatitis B virus (HBV) or hepatitis C virus (HCV) co-infections can be observed in human immunodeficiency virus (HIV)-infected cases and are associated with more severe clinical courses. The detection of HBV DNA despite HBV surface antigen (HBsAg) seronegativity is defined as occult HBV infections. According to the current seroepidemiological data, Turkey is classified as an intermediate HBV, low HIV endemic region. Occult HBV infections have previously been reported from Turkey but has not been investigated previously in HIV infected cohorts. The aim of this study was to identify occult HBV infections in HIV-infected persons. Twenty-eight HIV-positive cases followed-up at Hacettepe University Hospital, Infectious Diseases Unit were included in the study after informed consent. For the detection of HBsAg, anti-HBs and anti-HCV, commercial ELISA tests (Architect System, Abbott Diagnostics, USA) were employed. Absolute CD4+ and CD8+ T-cell counts were determined via flow cytometry. HIV viral load was calculated via COBAS TaqMan HIV-1 Real-time PCR (Roche Diagnostics, USA) and the presence of HBV DNA was evaluated via COBAS TaqMan HBV Real-time PCR (Roche Diagnostics, USA), in addition to a nested PCR assay targeting HBV S gene. The mean age of the study group was 43.2 (range between 27-65) years, 64.3% (18/28) of them were males and the mean duration of HIV infection was 4.2 (2-11) years. Mean CD4+ ve CD8+ T-cell counts were 414 ± 267 cells/mm3 and 854 ± 293 cells/mm3, respectively. Twenty-six (92.8%) cases were under highly-active anti-retroviral therapy at the time of the study, 88.5% of which included HBV-active drugs (lamivudine or tenofovir). HIV RNA were found negative in 11 (39.3%) patients, of those nine (81.8%) were the cases who treated with HBV-active antiretroviral therapy. HBsAg were negative in all of the 28 patients, while the positivity rates of anti-HBs and anti-HCV were 39.3% (11/28) and 3.6% (1

    Objective Nurse telephone counseling can improve the management of chronic conditions, but the effectiveness of this approach in underserved populations is unclear. This study evaluated the use of bilingual nurse-delivered telephone counseling in Korean Americans (KAs) participating in a community-based intervention trial to improve management of hypertension. Methods KAs were randomized to receive 12 months of hypertension-related telephone counseling that was more intensive (bi-weekly) or less intensive (monthly). Counseling logs were kept for 360 KAs who completed the pre- and post-intervention evaluations. Results The overall success rate for the intervention was 80.3%. The level of success was significantly influenced by the dose of counseling, employment status, and years of US residence. Over the 12-month counseling period, both groups showed improvement with regard to medication-taking, alcohol consumption, and exercise but not smoking, with no significant group differences. Conclusion Bilingual telephone counseling could reach monolingual KAs and improve their hypertension management behavior. Practice implications Bilingual nurse telephone counseling may have wide applicability, serving as an effective means of disseminating evidence-based chronic disease management guidelines to a linguistically isolated community with limited health resources and information.

    Usher syndrome type II (USH2) is the most common form of Usher syndrome, characterized by moderate to severe hearing impairment and progressive visual loss due to retinitis pigmentosa. It has been shown that mutations in the USH2A gene are responsible for USH2. The authors herein describe a 34-year-old Korean woman with the typical clinical manifestation of USH2; she had bilateral hearing disturbance and progressive visual deterioration, without vestibular dysfunction. Molecular genetic study of the USH2A gene revealed a novel frameshift mutation (c.2310delA; Glu771LysfsX17). She was heterozygous for this mutation, and no other mutation was found in USH2A, suggesting the possibility of an intronic or large genomic rearrangement mutation. To the best of our knowledge, this is the first report of a genetically confirmed case of USH2 in Korea. More investigations are needed to delineate genotype-phenotype correlations and ethnicity-specific genetic background of Usher syndrome. PMID:23526569

    The aim of the present study was to construct a cost-effective noninvasive diagnostic index for prediction of hepatic steatosis in patients with hepatitis B virus(HBV) infection. From January 2011 to January 2015, a total of 364 consecutive subjects who underwent liver biopsies were enrolled. The Receiver-operating characteristic(ROC) curves and Obuchowski measure were constructed to evaluate the diagnostic accuracy of the new index. The AUROCs of steatosis index of patients with HBV infection (SIHBV) in predicting of steatosis were 0.929 (95% confidence interval:0.889-0.970, P < 0.05) in the model group and 0.855 (0.794-0.917, P < 0.05) in the validation group respectively. Comparisons of AUROCs demonstrated that SIHBV was significantly superior to Korean Score, fatty liver index (FLI), hepatic steatosis index (HSI), lipid accumulation product(LAP), and fatty liver disease (FLD) index for prediction of hepatic steatosis in model group and validation group(all P < 0.01). Especially for patients with hepatic steatosis percentage of 5.0-9.9% and 10.0-19.9%, SIHBV had a sensitivity of 63.6% and 79.2%, whereas it were 29.1% and 45.8% for Ultrasonography (all P < 0.05). In conclusion, as a cost-effective, simple, noninvasive, and readily available method, SIHBV may act as a massive screening tool before further examinations such as MRI, CT, transient elastography, or liver biopsy, especially for developing countries.

    Background The present study examines the association between carotid and coronary atherosclerosis and metabolic syndrome in human immunodeficiency virus (HIV)–infected adults. Methods We measured the common and internal carotid intima-media thickness (c-IMT) using B-mode ultrasonography, and we measured coronary artery calcium (CAC) using high-resolution, electrocardiographic, synchronized, computed tomography, for 314 HIV-infected men and women. Metabolic syndrome was defined by National Cholesterol Education Program/Adult Treatment Panel III criteria. We compared the c-IMT measurements and CAC scores of patients with metabolic syndrome with the scores of those without metabolic syndrome using a Wilcoxon test for continuous variables and a χ2 test for categorical variables. To examine the association between surrogate markers and metabolic syndrome, we used logistic regression analysis. Results Participants with metabolic syndrome were more likely to have a common c-IMT measurement >0.8 mm than were those without metabolic syndrome (17% vs.7%; P=.009), but both groups were equally likely to have an internal c-IMT measurement >1.0 mm (20% vs. 13%; P=.15). Any positive CAC score was more likely to occur for participants with metabolic syndrome (80.3% vs. 46.7%; P < .0001). In a multivariate model adjusted for sex, age, ethnicity, and smoking status, participants with metabolic syndrome were more likely than those without metabolic syndrome to have an abnormal common c-IMT measurement (odds ratio [OR], 2.9; P= .020) and detectable CAC scores (OR, 4.9; P < .0001) but not a higher internal c-IMT measurement (OR, 1.6; P=.255). Conclusion Our study demonstrates that HIV-infected individuals with metabolic syndrome may be at increased risk for subclinical atherosclerosis and supports screening for metabolic syndrome among HIV-infected patients at risk for cardiovascular disease.

    Twenty five patients with peripheral neuropathy at different stages of human immunodeficiency virus (HIV) infection are reported. Cerebrospinal fluid (CSF) findings were available in 17 cases, electrophysiology in all and a neuromuscular biopsy in 11. Of six otherwise asymptomatic HIV+ patients, five had chronic inflammatory demyelinating polyneuropathy (CIDP) and one acute inflammatory demyelinating polyneuropathy (AIDP). CSF showed pleocytosis in all cases. Infiltration of the endoneurium and/or the epineurium by mononuclear cells was seen in biopsies from three cases. These six patients recovered either spontaneously, or with corticosteroids or plasmaphereses. Of five patients with AIDS related complex (ARC), three had distal predominantly sensory peripheral neuropathy (DSPN), one CIDP and one mixed neuropathy. Of 14 patients with AIDS, one had mononeuropathy multiplex and 13 painful DSPN. Electrophysiological studies were consistent with an axonopathy. Nerve biopsies in six cases showed axonal changes but surprisingly associated with marked segmental demyelination in two cases. Cell infiltration was present in nerve samples in two cases. Five patients died within six months after the onset of the neuropathy. PMID:2559161

    Hepatitis C signifies a highly prevalent infection in patients with end stage renal disease. Most frequently it is associated to glomerulonephritis, patients on hemodialysis and renal transplants. The prevalence of HCV antibodies in hemodialysis patients varies between 5-70% depending on the geographical location of the patients. Factors associated with the prevalence of anti HCV in patients with hemodialysis include: age, blood transfusions, tattoos, use of illegal drugs, time in hemodialysis, more than two hospitalizations, treatment in multiple hemodialysis units or a kidney transplant. In some of the reported outbreaks of hepatitis in hemodialysis units, the phylogenetic analysis indicate that the transmission of HCV could relate to failures or breaches in general precautions in the management of these type of patients resulting in nosocomial transmission owed to sharing equipment or instruments employed in the hemodialysis or by transmission from professional members of the hemodialysis units. Antiviral treatment may be affected by a number of co-factors and co-morbidities, it consist mainly of non pegylated interferon or pegylated interferon. The treatment with interferon after a renal transplant is associated with an increase in the number of rejections; reason enough to recommended that treatment should be administered before the transplant.

    Although Korea had a national surveillance system for Creutzfeldt-Jakob disease (CJD), it was mainly dependent on attending physician's reports. Thus, little prospective data about the epidemiology, characteristics, and final diagnoses of suspected patients were available. We have established a nationwide network for the active surveillance of patients with suspected CJD. When the requested cerebrospinal fluid (CSF) samples tested positive for 14-3-3 protein, we investigated the clinical characteristics of the corresponding patients and followed them until their final diagnoses were confirmed. A total of 218 samples were requested for CSF assays from May 2010 to August 2012, and 106 (48.6%) were positive for 14-3-3 protein. In 89 patients with complete clinical data, 38 (42.7%) were diagnosed with probable CJD and the estimated annual occurrence of CJD was 16.3 persons-per-year. The most common diagnoses of the remainder were central nervous system infection and any-cause encephalopathy. Non-CJD subjects showed worse initial consciousness levels than CJD patients. This preliminary study showed that the number of reported cases of CJD and the true positivity rates of CSF 14-3-3 protein assays were both low in Korea. An active surveillance system is urgently needed to provide the latest nationwide epidemiological data of CJD.

The HLA class I and II allele distribution was analyzed in 49 antiretroviral (ART)-treated HIV-positive patients with persistent warts, 42 noninfected controls, and 46 HIV-positive controls. The allele HLA-B*44 was more frequently identified in HIV-positive patients with warts (P = .004); a susceptible haplotype (HLA-B*44, HLA-C*05; P = .001) and protective genes (HLA-DQB1*06; P = .03) may also contribute. Cutaneous wart biopsy specimens from HIV-positive patients harbored common wart types HPV27/57, the unusual wart type HPV7, and an excess of Betapapillomavirus types (P = .002), compared with wart specimens from noninfected controls. These findings suggest that HLA testing might assist in stratifying those patients in whom vaccination should be recommended. PMID:26908737

    It is crucial to ensure an optimal clinical management of HCV infection in HIV-co-infected persons. The reasons for the development of guidelines on HCV-infection treatment in HIV-infected persons arise from the need for a standardised management of HIV/HCV coinfection in our Institute. The aim of these guidelines are: to clarify principles of clinical management of HCV infection in HIV-infected patients to care-providers; to improve the awareness of HIV-infected patients cared for our Institute on current management of HCV infection; to improve the quality of care on this topic. These guidelines, based on Evidence based Medicine principles, have been developed by a panel of experts, who conducted a systematic review of the literature, mainly taking into account current international recommendations. In the present document, the most frequent clinical presentation occurring in the management of HIV/HCV co-infected patients at our Institution are discussed. The adherence to present guidelines and their effectiveness at our Institution, outcome indicators will be evaluated. The present guidelines cannot entirely substitute the judgement of an expert clinician. However, adherence to these guidelines will contribute to the improvement of the standard of care of HIV/HCV-co-infected persons.

    Human babesiosis is a zoonosis primarily transmitted through Ixodes ticks and alternatively by routes such as blood transfusions from asymptomatic donors. We report the first case of human babesiosis caused by Babesia divergens in a patient with HIV. This study also focuses on elucidating the possible transmission route of infection in this patient, who received numerous blood transfusions but showed patent symptoms only after splenectomy. A battery of detection tools along with a novel Western-Blot Assay and Enzyme Linked Immunosorbent Assay using the major surface protein of B. divergens (Bd37) as a target were used to evaluate the presence of B. divergens or antibodies against the parasite in samples from the patient and the blood donors involved in this case. A retrospective study of the humoral status against the parasite revealed B. divergens IgG antibodies in one of the implicated donors, but also showed that the patient had been already exposed to the parasite before any transfusion. Thus, this analysis of natural and transfusion transmission routes suggests a pre-existing subclinical babesiosis in the patient. PMID:25686807

    Objective To validate a new risk stratification system for thyroid nodules, the Korean Thyroid Imaging Reporting and Data System (K-TIRADS), using a prospective design. Materials and Methods From June 2013 to May 2015, 902 thyroid nodules were enrolled from four institutions. The type and predictive value of ultrasonography (US) predictors were analyzed according to the combination of the solidity and echogenicity of nodules; in addition, we determined malignancy risk and diagnostic performance for each category of K-TIRADS, and compared the efficacy of fine-needle aspiration (FNA) with a three-tier risk categorization system published in 2011. Results The malignancy risk was significantly higher in solid hypoechoic nodules, as compared to partially cystic or isohyperechoic nodules (each p < 0.001). The presence of any suspicious US features had a significantly higher malignancy risk (73.4%) in solid hypoechoic nodules than in partially cystic or isohyperechoic nodules (4.3–38.5%; p < 0.001). The calculated malignancy risk in K-TIRADS categories 5, 4, 3, and 2 nodules were 73.4, 19.0, 3.5, and 0.0%, respectively; and the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for malignancy were 95.5, 58.6, 44.5, 96.9, and 69.5%, respectively, in K-TIRADS categories 4 and 5. The efficacy of FNA for detecting malignancy based on K-TIRADS was increased from 18.6% (101/544) to 22.5% (101/449), as compared with the three-tier risk categorization system (p < 0.001). Conclusion The proposed new risk stratification system based on solidity and echogenicity was useful for risk stratification of thyroid nodules and the decision for FNA. The malignancy risk of K-TIRADS was in agreement with the findings of a previous retrospective study. PMID:27587972

    The lung infection with Pseudomonas aeruginosa is regarded as one of the major causes of health decline in patients with cystic fibrosis (CF). The CF host response to the persistent bacterial antigen load in the endobronchiolar lumen is characterized by a pronounced humoral response, local production of cytokines, influx of neutrophils into the lung and a protease-protease inhibitor imbalance predominantly sustained by released neutrophil elastase. CF is an autosomal recessive disease, and we could demonstrate for our local patient population that the age-dependent risk to become chronically colonized with P. aeruginosa can be differentiated by the disease-causing CFTR mutation genotype. The age-specific colonisation rates were significantly lower in pancreas sufficient than in pancreas insufficient patients. P. aeruginosa is occasionally detected in throat swabs already in infancy or early childhood in most patients although there is a lapse of several years amenable to preventive measures such as vaccination until onset of persistent colonization. The epidemiology of the infection with P. aeruginosa was investigated by quantitative macrorestriction fragment pattern analysis. The distribution and frequency of clones found in CF patients match that found in other clinical and environmental aquatic habitats, but the over-representation of specific clones at a CF clinic indicates a significant impact of nosocomial transmission for the prevalence of P. aeruginosa-positive patients at a particular center. Most patients remain colonized with the initially acquired P. aeruginosa clone. According to direct sputum analysis the majority of patients is carrying a single clonal variant at a concentration of 10(7)-10(9) CFU. Co-colonization with other species or other clones is infrequent. Independent of the underlying genotype, the CF lung habitat triggers a uniform, genetically fixed conversion of bacterial phenotype. Most CFP, aeruginosa strains become non-motile, mucoid

    To understand the molecular mechanisms of parasitism in vivo, it is essential to elucidate how the transcriptomes of the human hosts and the infecting parasites affect one another. Here we report the RNA-seq analysis of 116 Indonesian patients infected with the malaria parasite Plasmodium falciparum (Pf). We extracted RNAs from their peripheral blood as a mixture of host and parasite transcripts and mapped the RNA-seq tags to the human and Pf reference genomes to separate the respective tags. We were thus able to simultaneously analyze expression patterns in both humans and parasites. We identified human and parasite genes and pathways that correlated with various clinical data, which may serve as primary targets for drug developments. Of particular importance, we revealed characteristic expression changes in the human innate immune response pathway genes including TLR2 and TICAM2 that correlated with the severity of the malaria infection. We also found a group of transcription regulatory factors, JUND, for example, and signaling molecules, TNFAIP3, for example, that were strongly correlated in the expression patterns of humans and parasites. We also identified several genetic variations in important anti-malaria drug resistance-related genes. Furthermore, we identified the genetic variations which are potentially associated with severe malaria symptoms both in humans and parasites. The newly generated data should collectively lay a unique foundation for understanding variable behaviors of the field malaria parasites, which are far more complex than those observed under laboratory conditions.

    Five cases of orf virus infection in Korean black goats were diagnosed in our laboratory between 2010 and 2011. One orf virus (ORF/2011) was isolated from an ovine testis cell line (OA3.Ts) for use as a vaccine candidate. Sequences of the major envelope protein and orf virus interferon resistance genes were determined and compared with published reference sequences. Phylogenetic analyses revealed that orf viruses from Korean black goats were most closely related to an isolate (ORF/09/Korea) from dairy goats in Korea. This result indicates that the orf viruses might have been introduced from dairy goats into the Korean black goat population.

    Invasive pulmonary aspergillosis (IPA) is a rare pathology with increasing incidence mainly in critical care settings and recently in immunocompetent patients. The mortality of the disease is very high, regardless of an early diagnosis and aggressive treatment. Here, we report a case of a 56 yr old previously healthy woman who was found unconscious at home and admitted to the emergency room with mild respiratory insufficiency. In the first 24 hours she developed an acute respiratory failure with new radiographic infiltrates requiring Intensive Care Unit admission. A severe obstructive pattern with impossibility of ventilation because of bilateral atelectasis was observed, requiring emergent venovenous extracorporeal membrane oxygenator device insertion. Bronchoscopy revealed occlusion of main bronchi, demonstrating by biopsy an invasive infection by Aspergillus fumigatus and A. flavus. Despite an aggressive treatment and vital support the patient had a fatal outcome. The forensic study confirms the diagnosis of IPA but also revealed the presence of disseminated aspergillosis.

    Purpose To evaluate the Recurrence Score® of the quantitative 12-multigene expression assay and to determine risk groups based on the continuous Recurrence Score® in Korean patients. Method A total of 95 patients with pathological T3N0 tumors and mismatch repair-proficient tumors were enrolled. The Recurrence Score® was used to classify risk groups (low risk, <30; intermediate risk, 30–40; high risk, ≥41). Results Fifty-four patients (56.8%) were aged over 70 years. There were 49 men (51.6%) and 56 cases of right-sided colon cancer (58.9%). Eight cases (8.4%) had well-differentiated tumors, and 86 cases (90.5%) showed moderate differentiation. Only one case (1.1%) had a poorly differentiated tumor. Three patients (3.2%) had lymphovascular invasion. Sixty-one patients were identified as low risk (64.2%) and 34 patients as intermediate risk (35.8%). There were no high-risk patients. Although not significant, the 3-year recurrence risk increased with the Recurrence Score®. Conclusion Distribution patterns of risk groups based on the Recurrence Score®, particularly the absence of a high-risk group, were different from the prior validation studies. These findings suggest that ethnic differences between Koreans and Western patients are potential contributing factors for different gene expressions in the quantitative 12-multigene expression assay.

    Rabson-Mendenhall syndrome (RMS) is a rare syndrome manifested by extreme insulin resistance with hyperinsulinemia, acanthosis nigricans, tooth dysplasia and growth retardation. Our patient was first noted at the age of 8 months due to pigmentations on skin-folded areas. Initial laboratory tests showed normal fasting glucose (69 mg/dL). Fasting insulin level was severely elevated, up to 554.6 µIU/mL, and c-peptide level was increased, up to 13.81 ng/mL. However, hemoglobin A1c was within normal range (4.8%). He is now 11 yr old. His growth development followed the 5-10th percentile and oral hypoglycemic agents are being administered. The last laboratory results showed insulin 364.1 µIU/mL, C-peptide 4.30 ng/mL, and hemoglobin A1c 7.6%. The boy was a compound heterozygote for the c.90C > A and c.712G > A mutations of the insulin receptor gene, INSR, which are nonsense and missense mutations. In summary, we report the first Korean case of RMS, which was confirmed by two novel mutations of the INSR. PMID:22563226

    Disseminated sporotrichosis occurs in individuals with impaired cellular immunity, such as in cases of neoplasia, transplantation, diabetes, and especially, acquired immunodeficiency syndrome. This report presents a 32-year-old Brazilian human immunodeficiency virus (HIV)-infected patient who developed a protracted condition of disseminated sporotrichosis with endocarditis, bilateral endophthalmitis, and lymphatic involvement. He needed cardiac surgery to replace the mitral valve. Sporothrix brasiliensis isolates were recovered from cultures of subcutaneous nodules and mitral valve fragments. Species identification was based on classical and molecular methods. The patient received amphotericin B for 52 days and subsequently, oral itraconazole. He remains asymptomatic, and he is on maintenance therapy with itraconazole. Despite his positive clinical outcome, he developed bilateral blindness. To our knowledge, this case is the first report of endocarditis and endophthalmitis caused by S. brasiliensis. PMID:22403321

    Background Few data on the virological determinants of hepatitis B virus (HBV) infection are available from southern Africa. Methods We enrolled consecutive HIV-infected adult patients initiating antiretroviral therapy (ART) at two urban clinics in Zambia and four rural clinics in Northern Mozambique between May 2013 and August 2014. HBsAg screening was performed using the Determine® rapid test. Quantitative real-time PCR and HBV sequencing were performed in HBsAg-positive patients. Risk factors for HBV infection were evaluated using Chi-square and Mann-Whitney tests and associations between baseline characteristics and high level HBV replication explored in multivariable logistic regression. Results Seventy-eight of 1,032 participants in Mozambique (7.6%, 95% confidence interval [CI]: 6.1–9.3) and 90 of 797 in Zambia (11.3%, 95% CI: 9.3–13.4) were HBsAg-positive. HBsAg-positive individuals were less likely to be female compared to HBsAg-negative ones (52.3% vs. 66.1%, p<0.001). Among 156 (92.9%) HBsAg-positive patients with an available measurement, median HBV viral load was 13,645 IU/mL (interquartile range: 192–8,617,488 IU/mL) and 77 (49.4%) had high values (>20,000 UI/mL). HBsAg-positive individuals had higher levels of ALT and AST compared to HBsAg-negative ones (both p<0.001). In multivariable analyses, male sex (adjusted odds ratio: 2.59, 95% CI: 1.22–5.53) and CD4 cell count below 200/μl (2.58, 1.20–5.54) were associated with high HBV DNA. HBV genotypes A1 (58.8%) and E (38.2%) were most prevalent. Four patients had probable resistance to lamivudine and/or entecavir. Conclusion One half of HBsAg-positive patients demonstrated high HBV viremia, supporting the early initiation of tenofovir-containing ART in HIV/HBV-coinfected adults. PMID:27032097

    Prevalence of HGV(GBV-C) infection and its coinfection with HBV a HCV infections were studied in group of 82 haemodialysis patients. This study was realized 20 months latter again -- 16 patients from 82 were running in dialysis, 17 patients were transplanted and 49 patients died (non of this viruses was cause of their death). HGV(GBV-C) RNA was detected in serum of 22 patients, 20 months latter it was detected in serum of 3 patients; one positive was new. 20 months latter any HGV(GBV-C) RNA was not detected in serum of 4 originally positive patients. Three of ten HBsAg positive patients were coinfected by HGV(GBV-C) RNA; 20 months latter any coinfection was found. In the first we found HGV(GBV-C) RNA in serum of 5 anti-HCV positive patients and in serum of 1 HCV RNA positive patient; 20 months latter it was in serum of 1 and 1 respectively. Elevation of ALT and AST levels were found in serum of 3 from 82 patients; two patients were coinfected with HBV or HCV. Any from 2 running dialysis patients with elevation of ALT and AST levels was not HGV(GBV-C) RNA positive. This virus is not probably frequent cause of liver disease in dialysis patients and it is not necessary to routinely screen for HGV(GBV-C) infection in this group of patients. PMID:19569590

To determine if daily bathing with Chlorhexidine gluconate can decrease the rate of nosocomial infection in pediatric oncology patients, we reviewed rates of infections in pediatric oncology patients over a 14-month span. Intervention group received daily bath with Chlorhexidine, while the control group did not receive daily bath. The results showed that daily bath with antiseptic chlorhexidine as daily prophylactic antiseptic topical wash leads to decreased infection density amongst the pediatric oncology patients, especially in patients older than 12 years of age. Furthermore, daily chlorhexidine bathing significantly reduced the rate of hospital acquired infection in patients older than 12 years of age. The findings of this study suggest that daily bathing with chlorhexidine may be an effective measure of reducing nosocomial infection in pediatric oncology patients.

    Caring for liver transplant patients suffering from chronic hepatitis C virus (HCV) infection is a challenging task for transplant surgeons and primary physicians alike. HCV is the leading cause of liver transplantation in the USA and comes with a myriad of complications that increase morbidity and mortality. This review focuses on patient follow-up, spanning from before the liver transplant occurs to the patient’s long-term health. Pretransplant, both donor and recipient variables, must be carefully chosen to ensure optimal surgical success. Risk factors must be identified and HCV viral load must be reduced to a minimum. In addition to standard transplant complications, HCV patients suffer from additional problems, such as fibrosing cholestatic hepatitis and widespread viremia. Physicians must focus on the balance of immunosuppressive and antiviral medications, while considering possible side effects from these potent drugs. Over the years following surgery, physicians must identify any signs of failing liver health, as HCV-positive patients have an increased risk for cirrhosis and certain life-threatening malignancies.

    West Nile virus (WNV), a mosquito-borne RNA virus for which there is no treatment, began emerging as a threat to health in the United States in 1999. Since then, its frequency and apparent clinical severity have increased. Patients with severe disease may experience ocular complications that include pain, vitreous inflammation, nonrelapsing chorioretinitis, retinal vasculitis, chorioretinal scarring, optic neuritis, and retinal hemorrhages. Age appears to be a risk factor for the development of ocular symptoms. Most patients with ocular involvement report floaters or decreased vision. Many ocular inflammatory conditions with an associated underlying systemic cause often present with chorioretinitis. However, the characteristic distribution and linear array or scattered pattern of the chorioretinal lesions seen in WNV is distinctive. The foregoing notwithstanding, other multifocal choroidopathies must be considered including syphilis, ocular histoplasmosis, multifocal choroiditis, tuberculosis, and sarcoid. Although topical steroids were reported to resolve WNV-induced uveitis and its associated keratic precipitates, most cases resolved irrespective of treatment, and relapses were uncommon. It is important for the eye care professional to be alert to the possible presence of WNV, particularly in older patients who present with ocular symptoms during mosquito season. Thus, a thorough ocular evaluation should include a dilated fundus examination and, when indicated, fluorescein angiography should be performed in patients suspected of being infected with WNV.

    Introduction As data from Clostridium difficile infection (CDI) in intensive care unit (ICU) are still scarce, our objectives were to assess the morbidity and mortality of ICU-acquired CDI. Methods We compared patients with ICU-acquired CDI (watery or unformed stools occurring ≥ 72 hours after ICU admission with a stool sample positive for C. difficile toxin A or B) with two groups of controls hospitalized at the same time in the same unit. The first control group comprised patients with ICU-acquired diarrhea occurring ≥ 72 hours after ICU admission with a stool sample negative for C. difficile and for toxin A or B. The second group comprised patients without any diarrhea. Results Among 5,260 patients, 512 patients developed one episode of diarrhea. Among them, 69 (13.5%) had a CDI; 10 (14.5%) of them were community-acquired, contrasting with 12 (17.4%) that were hospital-acquired and 47 (68%) that were ICU-acquired. A pseudomembranous colitis was associated in 24/47 (51%) ICU patients. The median delay between diagnosis and metronidazole administration was one day (25th Quartile; 75th Quartile (0; 2) days). The case-fatality rate for patients with ICU-acquired CDI was 10/47 (21.5%), as compared to 112/443 (25.3%) for patients with negative tests. Neither the crude mortality (cause specific hazard ratio; CSHR = 0.70, 95% confidence interval; CI 0.36 to 1.35, P = 0.3) nor the adjusted mortality to confounding variables (CSHR = 0.81, 95% CI 0.4 to 1.64, P = 0.6) were significantly different between CDI patients and diarrheic patients without CDI. Compared to the general ICU population, neither the crude mortality (SHR = 0.64, 95% CI 0.34 to 1.21, P = 0.17), nor the mortality adjusted to confounding variables (CSHR = 0.71, 95% confidence interval (CI) 0.38 to 1.35, P = 0.3), were significantly different between the two groups. The estimated increase in the duration of stay due to CDI was 8.0 days ± 9.3 days, (P = 0.4) in comparison to the diarrheic population

    This study investigates factors associated with the self-reported use of complementary therapies, types of therapies used, and sources of complementary therapy information among HIV-positive patients attending a public, HIV outpatient clinic in New Orleans. A convenience sample of 287 clients (220 men and 67 women) was given a self-administered anonymous questionnaire. Overall, complementary therapy use was 31%. Patients who used complementary therapy were more likely to be white (O.R., 2.5), female (O.R. 3.3), a high school graduate (O.R. 2.9), and to know another complementary therapy user (O.R. 7.8). Age, sexual orientation, CD4 cell count, injection drug use, living with another HIV-infected person, having pain, and HIV support group membership were not associated. Men were more likely than women, and whites were more likely than nonwhites, to use vitamins/minerals, imagery/meditation, and dietary regimens. Nonwhites were more likely than whites, and women more likely than men, to use spiritual healing. Of those using complementary therapy, men were more likely than women, and whites more likely than nonwhites, to get information about complementary therapy from HIV organizations, friends, and homosexual-oriented media. Doctors and nurses were the most frequently cited source of complementary therapy information for women. Frequency, type of therapies used, and source of information about complementary therapy among HIV-infected persons vary by race and gender. Clinicians should be educated about complementary therapies so that they can provide information to their patients and be aware of self-treatment behavior.

    Hepatitis B virus (HBV) vaccination is recommended for HIV patients. Despite the relative success of HBV vaccination, breakthrough infections can occur infrequently in patients, and it can be due to occult HBV infection, vaccine unresponsiveness and/or emergence of escape mutants. This study assessed the presence of occult HBV infection and S gene escape mutants in HIV-positive patients after HBV vaccination. Ninety-two HIV-positive patients were enrolled in this study, including 52 responders to HBV vaccine and 40 non-responders. All of the cases received HBV vaccine according to routine HBV vaccination protocols. The presence of HBV-DNA was determined by real-time polymerase chain reaction (PCR). In HBV-DNA positive samples, the most conserved regions of S gene sequences were amplified by nested PCR and PCR products were sequenced. Occult HBV infection was detected in two cases. Glycine to arginine mutation at residue 145 (G145R) within the 'a' region of the S gene was detected in one of the occult HBV infection cases who was in the non-responder group. This study showed that the prevalence of occult HBV infection and vaccine escape mutants was low in our HBV-vaccinated HIV-positive patients in both responder and non-responder groups, so there was no alarming evidence indicating breakthrough HBV infection in our vaccinated HIV-positive cases.

    Cryptosporidiosis has been reported to be associated with HIV/acquired immune deficiency syndrome, which greatly reduces the quality of life and shortens the life expectancy of HIV-infected patients. In order to properly treat the infected patients, accurate and automatic diagnostic tools need to be developed. In this study, a novel microfluidic immunochip system was presented for the surveillance and the rapid detection of Cryptosporidium infection in 190 HIV-infected patients from Guangxi, China, using the P23 antigen of Cryptosporidium. The procedure of detection can be completed within 10 min with 2 μl sample consumption. The system also was evaluated using the standard ELISA method. Among 190 HIV-infected individuals, the rate of P23 positivity was 13.7%. Seropositivity in HIV-infected individuals was higher in female patients. The seropositivity to P23 was higher in HIV-infected individuals with high viral load, although the difference was statistically insignificant. Significantly higher Cryptosporidium seropositivity was observed in HIV-infected individuals with a CD4+ T-cell count of <200 cells/μl than in those with ≥200 cells/μl. Our results also demonstrate that a lower CD4+ T-cell count may reflect an increased accumulated risk for cryptosporidiosis. The detection system was further validated using the standard ELISA method and good correlation between the two methods was found (r = 0.80). Under the same sensitivity, this new microfluidic chip device had a specificity of 98.2%. This developed system may provide a powerful platform for the fast screening of Cryptospordium infection in HIV-infected patients. PMID:25945140

    Background We investigated the prevalence, awareness, treatment, and control rate of hypertension in Korean adults with diabetes using nationally representative data. Methods Using data of 5,105 adults from the fifth Korea National Health and Nutrition Examination Survey in 2011 (4,389 nondiabetes mellitus [non-DM]), 242 newly diagnosed with DM (new-DM), and 474 previously diagnosed with DM (known-DM), we analyzed the prevalence of hypertension (mean systolic blood pressure ≥140 mm Hg, diastolic blood pressure ≥90 mm Hg, or use of antihypertensive medication) and control rate of hypertension (blood pressure [BP] <130/80 mm Hg). Results The prevalence of hypertension in diabetic adults was 54.6% (44.4% in new-DM and 62.6% in known-DM, P<0.0001 and P<0.0001, respectively) compared with non-DM adults (26.2%). Compared to non-DM, awareness (85.7%, P<0.001) and treatment (97.0%, P=0.020) rates were higher in known-DM, whereas no differences were found between new-DM and non-DM. Control rate among all hypertensive subjects was lower in new-DM (14.9%), compared to non-DM (35.1%, P<0.001) and known-DM (33.3%, P=0.004). Control rate among treated subjects was also lower in new-DM (25.2%), compared to non-DM (68.4%, P<0.0001) and known-DM (39.9%, P<0.0001). Conclusion Higher prevalence and low control rate of hypertension in adults with diabetes suggest that stringent efforts are needed to control BP in patients with diabetes, particularly in newly diagnosed diabetic patients.

    Toxoplasmosis is one of the most common opportunistic parasitic diseases in patients living with HIV/AIDS. This study aimed to determine the seroprevalence of Toxoplasma infection in HIV-infected patients and to identify associated risk factors in Toxoplasma seropositive patients. This study was conducted at a regional public hospital in Hat Yai, southern Thailand during October 2009 to June 2010. Blood samples were collected from 300 HIV-infected patients. Each subject also answered a socio-demographic and risk factors associated with Toxoplasma infection. The prevalence of anti-Toxoplasma IgG antibodies in HIV-infected patients was 109 (36.3%), of which 83 (76.2%) had past infection and 26 (23.9%) had recently acquired Toxoplasma infection as indicated by their IgG avidity. Multivariate analysis using logistic regression showed that gender difference (adjusted OR = 1.69, 95% CI = 1.05-2.72) was the only factor associated with Toxoplasma infection. From the results obtained, these HIV-infected patients could be at high risk of developing clinical evidence of severe toxoplasmosis. Therefore, it is necessary to introduce primary behavioral practices to prevent Toxoplasma infection among HIV-infected patients. PMID:26635769

    Although hepatitis B virus (HBV) and human immunodeficiency virus (HIV) co-infection is common, only few data are available on HBV among HIV patients including occult hepatitis B infection (OBI), regardless of serological markers. This study aims to determine the prevalence of OBI and overall HBV infection, associated factors, HBV genotypes, and surface (S) gene mutations in a population of treatment-naïve HIV-infected patients in Brazil. A cross-sectional study was conducted in treatment-naïve HIV-infected patients in Central Brazil. All samples were tested for HBV serological markers and HBV DNA. Sequence analysis of the S gene and overlapping polymerase gene was preformed. Overall, 25.1% (127/505) of the patients had markers of current or previous HBV infection, which was associated with age over 40 years, history of injection drug use, and homosexual sex. The hepatitis B surface antigen (HBsAg) seroprevalence was 4.9% (25/505). HBV DNA was detected in 39 out of 505 patients: 20 of them were HBsAg-positive and 19 were HBsAg-negative, resulting in an OBI prevalence of 3.8%. Patients with OBI had significantly higher HCV seropositivity rate compared to HBsAg-positive patients. Sequencing of the S gene revealed Y100C, T131N, and D144A mutations. One patient had the M204I and L180M drug-resistance mutations (polymerase). HBV genotypes A (A1, A2), D (D2, D3), and F (F2) were identified. In conclusion, OBI represented almost half of all HBV infections with detectable HBV DNA, suggesting that hepatitis B diagnosis in HIV patients should include in addition to serological markers the detection of HBV DNA.

    Urinary tract infections (UTIs) are symptomatic infections of the urinary tract, mainly caused by the bacterium Escherichia coli. One in two women suffers from a UTI at least once in her life. The young and sexually active are particulaly affected, but it is also seen in elderly, postmenopausal women. The likelihood of recurrence is high. Diagnosis is made with regard to typical complaints and the presence of leucocytes and nitrites in the urine. A culture is unnecessary in most cases. Uncomplicated UTI should be distinguished from complicated UTI, which has a risk of severe illness. The treatment of choice--short-term therapy with trimethoprim or nitrofurantoin--is successful in over 80% of the cases. Co-trimoxazol fluoroquinolones or cephalsporins are not considered first-choice drugs. There are indications that general practitioners' (GPs') management of UTI is not always optimal, specifically concerning diagnostic tests, the application of second-choice antibiotics, and the length of prescribed treatment courses. Many points relevant to GPs requirefurther research, such as epidemiology and resistance of urinary pathogens in the community and natural history of UTI, as well as optimal management in elderly or complicated patients and men.

    AIDS is one of the serious global health concerns caused by Human Immuno Deficiency(HIV) virus and is predominantly a sexually transmitted disease. Currently there is no vaccine or cure for AIDS still Anti Retroviral Therapy (ART) is successful. It reduces both the mortality and the morbidity of HIV infection, but is expensive and inaccessible in many countries. However intense the therapy may be, HIV virus is rarely eliminated, and drug resistance is a major setback during long-term therapy. The development of new drugs and strategies and exploring alternative systems of medicine for antiviral herbs or drugs is the need of the age to improve treatment outcomes. Ayurveda describes many diseases which incorporate HIV like illness e.g. Rajayakshma, Ojo Kshaya, Sannipata jwara etc. HIV infection affects multisystems, chiefly the Immune System which can be correlated to Ojo Kshaya. Rasayana Chikitsa is the frontline therapy employed to treat Ojus disorders. Therefore Shilajatu (Mineral pitch), Centella asiatica (Mandukaparni), Tinospora cordifolia (Guduchi) and Emblica officinalis (Amalaki), well known for their Immuno-modulator and antioxidant properties were selected to evaluate their role on immune system. The study was carried on 20 patients from OPD and IPD of Kayachikitsa, S.S.Hospital, IMS, BHU and was randomly allocated into Treated group (Shilajatu+ART) and Control group (ART). Treated Group responded better to ART both clinically and biochemically. The results show that Shilajatu decreases the recurrent resistance of HIV virus to ART and improves the outcome of the therapy PMID:22131681

    The results of bacteriological studies made between 1964 and 1971 by workers at the Varia Laboratory, Institute of Medical Microbiology on 767 patients treated at the Clinic of Gnathofacial Surgery, Department of Medicine, Friedrich Schiller University at Jena, are evaluated. The testees (x=275) were included in groups with specific diagnoses, and a breakdown was made according to the detection of aerobic pus-forming germs. Gram-positive cocci were detected in 92% of the cases and their pathogenetic representatives, 76,5% of the cases. Rodshaped germs (Enterobacteriaceae, Pseudomonas) were observed only in 37,9% of the cases. Staphylococcus aureus, which accounted for 62,5%, was the most frequently observed species. It was followed, in order of frequency of detection, by greening streptococci and Staphylococcus epidermidis. Monoinfection was far more frequently observed than multi-infection. Also, the problems associated with the differentiation of streptococci are pointed out since other investigators found streptococci to be the most frequent agents producing odontogenic infections.

    Disseminated Scedosporium prolificans infection occurs mainly in immunocompromised patients. The mortality rate is high, as the fungus is resistant to most antifungal agents. Here, we present the case of a 66-year-old female with acute myeloid leukemia who developed infective endocarditis caused by S. prolificans infection during induction chemotherapy. Her 1,3-β-D-glucan levels were elevated and computed tomography revealed bilateral sinusitis and disseminated small nodular masses within the lungs and spleen; it nonetheless took 6 days to identify S. prolificans by blood culture. The patient died of multi-organ failure despite the combined use of voriconazole and terbinafine. Autopsy revealed numerous mycotic emboli within multiple organs (caused by mitral valve vegetation) and endocarditis (caused by S. prolificans). The geographic distribution of this infection is limited to Australia, the United States, and southern Europe, particularly Spain. The first Japanese case was reported in 2011, and four cases have been reported to date, including this one. Recently, the incidence of S. prolificans-disseminated infection in immunocompromised patients has increased in Japan. Therefore, clinicians should consider S. prolificans infection as a differential diagnosis when immunocompromised patients suffer disseminated infections with elevated 1,3-β-D-glucan levels.

    Mycobacterium tuberculosis (MTB) and human immunodeficiency virus (HIV) coinfection remains a global public health challenge. We report a 40 year old African American male who is a known HIV-positive patient, non-compliant with his antiretrovirals and developed pulmonary tuberculosis. His chief complaints were chronic cough, fever, night sweats and undocumented weight loss. He had a prior positive T-SPOT-TB test; however, chest radiograph and sputum smear examination revealed normal results. PCR-based GeneXPERT MTB/RIF assay was ordered and confirmed MTB infection. The sputum cultures grew MTB and sensitivities showed susceptibility to all primary anti-tuberculosis medications. A delay in diagnosis and initiation of MTB therapy, in the setting of HIV or AIDS, may result in rapid disease progression and worse clinical outcome. PMID:26744689

    BACKGROUND Infection in systemic lupus erythematosus (SLE) is common and is one of the leading causes of morbidity and mortality. OBJECTIVE To study the risk and occurrence of infection in Egyptian SLE patients and to determine its characteristics. METHODS A total of 200 SLE patients were followed up for 1 year at monthly intervals, undergoing clinical and laboratory evaluation. Disease activity was assessed by SLE disease activity measurement (SLAM) score. Infections were diagnosed on basis of clinical findings, medical opinion, positive blood and urine cultures, Gram stain results, and specific serological assays as measurement of CMV and EBV antibodies. RESULTS A total of 55% of patients developed infection, 45% had one infection, and the rest had multiple infection episodes. Total number of infections was 233 infections/year, 47.2% were major and 52.8% were minor infections. Urinary tract was the most commonly involved site with bacterial infection being the commonest isolated organism (46.4%), and E. coli the commonest isolated bacteria (14.2%). There were 51 episodes caused by systemic viral infection (CMV in 25, EBV in 22, HCV in 3, and 1 in HBV). CONCLUSION There is a high rate of infection among SLE patients. Disease activity, leukopenia, high CRP level, positive anti-dsDNA, consumed C3, and cyclophosphamide therapy are independent risk factors for infection in SLE. PMID:25125988

    Objective: To investigate the differences of T lymphocyte subgroups and high-sensitivity C reactive protein (HsCRP) levels among patients with venous thromboembolism (VTE), VTE patients with infection, simple infection patients and the normal controls. Method: 289 patients were enrolled in this study and divided into control group, VTE group, VTE with infection group and simple infection group. Result: Compared with the control group, the serum levels of CD3+, CD4+, CD8+ T lymphocytes significantly decreased and CD4+/CD8+ ratio significantly increased in simple infection group (P < 0.05); CD3+ and CD8+ T lymphocytes significantly decreased and CD4+/CD8+ ratio significantly increased in VTE and VTE with infection group (P < 0.05); the proportion of declined CD3+ and CD8+ T lymphocytes increased, and the proportion of increased CD4+/CD8+ ratio statistically elevated in three disease groups. As an important inflammatory factor, all HsCRP levels in three disease groups significantly increased when compared with the control group. Conclusion: Immune dysfunction exists in both of VTE and infection patients, while VTE patients tend to be accompanied with infections. The changes of T lymphocyte subgroups in VTE patients, who were independent from infection, could cause T lymphocyte immune dysfunction, suggesting that there were abnormalities of T lymphocyte immune function in VTE itself. The overall T lymphocyte functions of recognizing antigens and transducing activation signals decline in VTE patients. Besides, the function of T lymphocyte of directly killing virus microbes declines significantly and the inflammatory mechanisms are involved in the occurrence and development of venous thrombosis.

    2015-04-01

    The spectrum of bacterial pathogens encountered in cystic fibrosis (CF) lung disease has expanded over the last decade. In addition to established pathogens, such as Pseudomonas aeruginosa, Burkholderia cepacia complex and Staphylococcus aureus, novel Gram-negative non-fermenter bacteria and non-tuberculous mycobacteria have gained in clinical significance. Air sampling performed in inpatient and outpatient clinics, and analysis of cough aerosols expelled by CF patients provides evidence for potential airborne transmission of CF pathogens. Two outbreaks of 'Mycobacterium abscessus subsp. massiliense' have been reported among CF patients, raising the question of airborne transmission of non-tuberculous mycobacteria. In response to newer epidemiological evidence, international infection control guidance documents have changed. Guideline documents agree on the importance of specifications for ventilation when planning new CF inpatient facilities. New CF units should consider providing negative-pressure inpatient and outpatient rooms to diminish the risk of airborne contamination of ward corridors and communal areas. Air exchange rates of inpatient rooms and pulmonary function testing rooms need to be considered and optimized whenever possible. International guidelines disagree as to whether patients should be requested to wear masks in the hospital environment. PMID:25791927

    To examine rates of Shigella infections in household contacts of pediatric shigellosis patients, we followed contacts and controls prospectively for 1 week after the index patient obtained care. Household contacts of patients were 44 times more likely to develop a Shigella infection than were control contacts (odds ratio 44.7, 95% CI 5.5–361.6); 29 (94%) household contacts of shigellosis patients were infected with the same species and serotype as the index patient’s. Pulsed-field gel electrophoresis showed that 14 (88%) of 16 with infected contacts had strains that were indistinguishable from or closely related to the index patient’s strain. Latrine area fly counts were higher in patient households compared with control households, and 2 patient household water samples were positive for Shigella. We show high susceptibility of household contacts of shigellosis patients to Shigella infections and found environmental risk factors to be targeted in future interventions. PMID:26484778

    Antiretroviral therapy advances have proportioned to AIDS patients a survival increase. At the same time, the permanence of the seropositive people in the nosocomial environment becomes common not only by the adverse reactions caused by this therapy, but also by several opportunistic diseases that take them into and out of hospital environment. During the hospital permanence, the patients expose their impaired immune system to the nosocomial virulent microorganisms, and acquire destructive nosocomial infections that sometimes can be lethal. Among several hospital syndromes described, little is known about infections in immunocompromised patients and how their immune system is able to determine the course of the infection. The objective of this study was to describe the major microorganisms involved in the nosocomial infections of HIV-1 seropositive patients associated with their immunological status. The survey was carried out with the Hospital Infection Control Service records, from University Hospital, Londrina, Paraná, Southern of Brazil, during the period from July 2003 to July 2004. From all the cases studied (n=969), 24 patients (2.5%) had AIDS diagnosis and a half of them was women with the mean of CD4+ T cells counts of 158/mm3. The main topography of the infection was pulmonary (50.0%) and the main isolated microorganisms were Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. A major incidence of infection was observed in patients with CD4+ T cells counts lower than 50/mm3. The study of the relationship between the impairment of the immune system and infectious agents could provide a better healthcare of people living with HIV/AIDS and advances into the nosocomial infection control systems.

    Peripheral artery disease (PAD) is an important marker for the risk stratification of patients with coronary artery disease (CAD). We investigated the prevalence of PAD in patients undergoing percutaneous coronary intervention (PCI) with CAD and the relationship between ankle-brachial pressure index (ABPI) and CAD severity. A total of 711 patients undergoing PCI for CAD from August 2009 to August 2011 were enrolled. PAD diagnosis was made using the ABPI. The prevalence of PAD was 12.8%. In PAD patients, mean values of right and left ABPI were 0.71 ± 0.15 and 0.73 ± 0.15. Patients with PAD had a higher prevalence of left main coronary disease (14.3% vs 5.8%, P = 0.003), more frequently had multivessel lesions (74.9% vs 52.1%, P < 0.001) and had higher SYNTAX score (18.2 ± 12.3 vs 13.1 ± 8.26, P = 0.002). Using multivariate analysis, we determined that left main CAD (OR, 2.954; 95% CI, 1.418-6.152, P = 0.004) and multivessel CAD (OR, 2.321; 95% CI, 1.363-3.953, P = 0.002) were both independently associated with PAD. We recommend that ABPI-based PAD screening should be implemented in all patients undergoing PCI with CAD, especially in severe cases. PMID:23341717

    To perform a valid comparison of rates among surgeons, among hospitals, or across time, surgical wound infection (SWI) rates must account for the variation in patients' underlying severity of illness and other important risk factors. From January 1987 through December 1990, 44 National Nosocomial Infections Surveillance System hospitals reported data collected under the detailed option of the surgical patient surveillance component protocol, which includes definitions of eligible patients, operations, and nosocomial infections. Pooled mean SWI rates (number of infections per 100 operations) within each of the categories of the traditional wound classification system were 2.1, 3.3, 6.4, and 7.1, respectively. A risk index was developed to predict a surgical patient's risk of acquiring an SWI. The risk index score, ranging from 0 to 3, is the number of risk factors present among the following: (1) a patient with an American Society of Anesthesiologists preoperative assessment score of 3, 4, or 5, (2) an operation classified as contaminated or dirty-infected, and (3) an operation lasting over T hours, where T depends upon the operative procedure being performed. The SWI rates for patients with scores of 0, 1, 2, and 3 were 1.5, 2.9, 6.8, and 13.0, respectively. The risk index is a significantly better predictor of SWI risk than the traditional wound classification system and performs well across a broad range of operative procedures.

    Levels of the soluble form of the interleukin-1 receptor like 1 protein (IL-1RL-1 / ST2) are elevated in the serum of patients with diseases characterized by an inflammatory response. The objective of this study was to determine the concentration of soluble ST2 (sST2) in dengue infected patients during the course of the disease. Twenty four patients with confirmed dengue infection, classified as dengue fever, and eleven patients with other febrile illness (OFI) were evaluated. Levels of sST2 in serum and laboratory variables usually altered during dengue infections were measured. Dengue infected patients had higher serum sST2 levels than OFI at the end of the febrile stage and at defervescence (p=0.0088 and p=0.0004 respectively). Patients with secondary dengue infections had higher serum sST2 levels compared with patients with primary dengue infections (p=0.047 at last day of fever and p=0.030 at defervescence). Furthermore, in dengue infected patients, we found a significant negative correlation of sST2 with platelet and WBC counts, and positive correlation with thrombin time and transaminases activity. We suggest that sST2 could be a potential marker of dengue infection, could be associated with severity or could play a role in the immune response in secondary dengue virus infection. PMID:18226917

    Introduction BRCA mutation testing allows index patients and their families to be provided with appropriate cancer risk-reduction strategies. Because of the low prevalence of BRCA mutations in unselected breast cancer patients and the high cost of genetic testing, it is important to identify the subset of women who are likely to carry BRCA mutations. In the present study, we examined the association between BRCA1/2 germline mutations and the immunohistochemical features of breast cancer. Methods In a retrospective review of 498 breast cancer patients who had undergone BRCA testing at Seoul National University Bundang Hospital between July 2003 and September 2012, we gathered immunohistochemical information on estrogen receptor (er), progesterone receptor (pr), her2 (human epidermal growth factor receptor 2), cytokeratin 5/6, egfr (epidermal growth factor receptor), and p53 status. Results Among the 411 patients eligible for the study, 50 (12.2%) had germline mutations in BRCA1 or BRCA2. Of the 93 patients with triple-negative breast cancer (tnbc), 25 with BRCA1/2 mutations were identified (BRCA1, 20.4%; BRCA2, 6.5%). On univariate analysis, er, pr, cytokeratin 5/6, egfr, and tnbc were found to be related to BRCA1 mutations, but on multivariate analysis, only tnbc was significantly associated with BRCA1 mutations. Among patients with early-onset breast cancer or with a family history of breast or ovarian cancer, BRCA1 mutations were significantly more prevalent in the tnbc group than in the non-tnbc group. Conclusions In the present study, tnbc was the only independent predictor of BRCA1 mutation in patients at high risk of hereditary breast and ovarian cancers. Other histologic features of basal-like breast cancer did not improve the estimate of BRCA1 mutation risk. PMID:27803593

    Purpose Laparoscopic sleeve gastrectomy (LSG) has been gaining marked popularity as a stand-alone treatment for morbid obesity. This study aimed to evaluate the midterm outcomes and efficacy of LSG performed at a single center in Korea. Methods The records of 192 consecutive patients who underwent LSG between April 2009 and December 2012 were retrospectively reviewed. The patients' demographics and surgical outcomes including anthropometric data were analyzed. Results The mean preoperative body mass index was 40.0 ± 7.2 kg/m2, and 120 patients (62.5%) had at least one obesity-related comorbidity. Three patients (1.6%) required endoscopic or surgical intervention to manage postoperative bleeding or leakage. At the postoperative 1-, 2-, 3-, and 4-year follow-ups, the mean percent of excess weight loss (%EWL) values were 72.6%, 80.6%, 71.1%, and 57.8%, respectively, with follow-up rates of 81%, 56%, 58%, and 30% respectively. The overall mean %EWL reached 68.3% ± 27.2% at a mean follow-up of 25 months. Obesity-related comorbidities were resolved in >70% of the patients after surgery. Twelve months after LSG, 25 patients (13.0%) showed a %EWL of <50%; 9 (4.7%) required conversion to gastric bypass due to inadequate weight loss, intolerable reflux symptoms, or intractable diabetes. Conclusion These midterm results show that LSG is a safe and effective surgical procedure for morbidly obese patients. However, a longer follow-up period is necessary to elucidate whether LSG can achieve durable weight loss and long-term outcomes, comparable to those of more aggressive procedures. PMID:25960987

    Genomic mutations occurring during reverse transcription of hepatitis B virus (HBV) could explain its genetic diversity and account for 8 genetically distinct genotypes that are geographically distributed quite differently. The main objectives of this study were to determine the prevalence of hepatitis B virus genotypes in patients with chronic hepatitis B and to see if there was a relationship between genotypes and risk factors for transmission based on HBeAg status. A total of 14 serum samples were analyzed using INNO-LIPA HBV genotyping assay. Genotype D was the most prevalent (64.3%) followed by genotype A (28.6%). There was one case of co-infection (D/E genotypes) that was confirmed by PCR sequencing. All patients except one were HBeAg-negative and anti-HBe-positive. The risk factors for HBV transmission were unknown in half of the cases; in the other half, sexual, transfusion, maternal or interfamilial transmission were observed. The results show that genotype D is the most prevalent genotype in our hospital, followed by genotype A. On the other hand, no relationship was found between HBeAg status and genotype.

    Scrub typhus is an infectious disease caused by Orientia tsutsugamushi-induced systemic vasculitis, but the involvement of the gastrointestinal tract and the endoscopic findings associated with scrub typhus are not well understood. We performed a prospective study and recommend performing esophagogastroduodenoscopy (EGD) for all possible scrub typhus patients, regardless of gastrointestinal symptoms. Gastrointestinal symptoms, endoscopic findings and clinical severity based on organ involvement and ICU admission were analyzed. Gastrointestinal symptoms occurred in up to 76.4% of scrub typhus patients. The major endoscopic findings were ulcers (43/127, 33.9%). Interestingly, 7.1% (9/127) of the patients presented with esophageal candidiasis. There was no correlation between the presence or absence of gastrointestinal symptoms and the endoscopic grade (P = 0.995). However, there was a positive correlation between the clinical severity and the endoscopic findings (P = 0.001). Sixty-three percent of the patients presented with erosion or ulcers on prospectively performed endoscopic evaluations, irrespective of gastrointestinal symptoms. Gastrointestinal symptoms did not reflect the need for endoscopy. Scrub typhus patients could have significant endoscopic abnormalities even in the absence of gastrointestinal symptoms.

Good therapeutic results achieved in patients treated with prednisolone and cyclophosphamide suggest inhibiting action of glucocorticoids on Mycoplasma infection.

    The rate of diagnosis of colonization/infection of the airways with Achromobacter xylosoxidans has increased in cystic fibrosis patients, but its clinical significance is still controversial. This retrospective, case-control study aimed to evaluate the clinical impact of A. xylosoxidans colonization/infection in cystic fibrosis patients. Individuals who were chronically colonized/infected (n=10), intermittently colonized/infected (n=15), and never colonized/infected with A. xylosoxidans (n=18) were retrospectively evaluated during two periods that were 2 years apart. Demographic characteristics, clinical data, lung function, and chronic bacterial co-colonization data were evaluated. Of the total study population, 87% were pediatric patients and 65.1% were female. Individuals chronically colonized/infected with A. xylosoxidans had decreased forced expiratory volume in 1 s (51.7% in the chronic colonization/infection group vs 82.7% in the intermittent colonization/infection group vs 76% in the never colonized/infected group). Compared with the other two groups, the rate of co-colonization with methicillin-resistant Staphylococcus aureus was higher in individuals chronically colonized/infected with A. xylosoxidans (P=0.002). Changes in lung function over 2 years in the three groups were not significant, although a trend toward a greater decrease in lung function was observed in the chronically colonized/infected group. Compared with the other two groups, there was a greater number of annual hospitalizations in patients chronically colonized/infected with A. xylosoxidans (P=0.033). In cystic fibrosis patients, there was an increased frequency of A. xylosoxidans colonization/infection in children, and lung function was reduced in patients who were chronically colonized/infected with A. xylosoxidans. Additionally, there were no differences in clinical outcomes during the 2-year period, except for an increased number of hospitalizations in patients with A. xylosoxidans.

    Hepatitis C virus (HCV) infection is the most common chronic blood-borne infection in the United States; the prevalence in maintenance hemodialysis patients substantially exceeds that in the general population. In hemodialysis patients, HCV infection has been associated with increased occurrence of cirrhosis and hepatocellular carcinoma and increased mortality. Injection drug use and receipt of blood transfusions before 1992 has accounted for most prevalent HCV infections in the United States. However, HCV transmission among patients undergoing hemodialysis has been documented frequently. Outbreak investigations have implicated lapses in infection control practices as the cause of HCV infections. Preventing these infections is an emerging priority for renal care providers, public health agencies, and regulators. Adherence to recommended infection control practices is effective in preventing HCV transmission in hemodialysis facilities. In addition, adoption of routine screening to facilitate the detection of incident HCV infections and hemodialysis-related transmission is an essential component of patient safety and infection prevention efforts. This article describes the current epidemiology of HCV infection in US maintenance hemodialysis patients and prevention practices to decrease its incidence and transmission.

    Study Design Prospective study. Purpose To evaluate the reliability and validity of the adapted Korean version of the Quality of Life Questionnaire of the European Foundation for Osteoporosis (ECOS-16). Overview of Literature The validity of the Korean version of ECOS-16 has not been completely demonstrated. Methods Translation/retranslation of the English version of ECOS-16, and full cross-cultural adaptation were performed. The Korean version of a visual analog scale measure of pain, and the Korean versions of ECOS-16 and of the previously validated short form-36 (SF-36) were mailed to 158 consecutive patients with osteoporosis. Factor analysis and reliability assessment using kappa statistics of agreement for each item, intraclass correlation coefficient, and Cronbach's α were done. Construct validity was evaluated by comparing responses to ECOS-16 with responses to SF-36 using Pearson's correlation coefficient. Results Factor analysis extracted three factors. All items had a kappa statistics of agreement >0.6. The ECOS-16 showed good test/re-test reliability (0.8469) and internal consistency of Cronbach's α (0.897). The Korean version of ECOS-16 showed significant correlation with SF-36 total scores and with single SF-36 domains scores. Conclusions The adapted Korean version of the ECOS-16 was successfully translated and showed acceptable measurement properties. It is considered suitable for outcome assessments in Korean patients with osteoporosis. PMID:27790315

    There is controversy regarding the impact of infection on long-term prognosis in osteosarcoma patients. Clinical trials and experiments relating to this field could bring reconsideration of immunotherapy for osteosarcoma. The clinical records were reviewed of 125 osteosarcoma patients with a mean follow-up of 5.1±3.9 years (range, 0.5–19.8 years), and a review of the literature was also carried out. Chronic localized infections (but not systemic infection) were determined in 6 patients (4.8%). Similar chemotherapeutic regimens (P=1.00) and histological reactions (P=0.65) were observed in patients with or without infection. Tumor location of proximal tibia (P=0.04) was more common in infected patients. More amputations (P<0.001) were necessitated in infected patients due to uncontrolled infection. The 5-year overall survival rate and event-free survival rate in infected patients were 100%, which were significantly higher than that of the non-infected patients, of whom the rates were 54 and 43% respectively (log-rank test: total survival, P=0.01; tumor-free survival, P=0.01). Distant metastasis was an independent risk factor for survival determined by Cox regression analysis (P<0.001, 95 confidence interval, 1.59–3.98). These findings suggested infection was likely to have positive effects on survival in osteosarcoma patients, however, underlying mechanisms remain to be elucidated. Reconsideration of the association of infection and survival in osteosarcoma patients will help to explore novel therapeutic routes and targets in these patients. PMID:26137256

    Estimates of occult hepatitis B virus (HBV) infection prevalence varies among different studies depending on the prevalence of HBV infection in the study population and on the sensitivity of the assay used to detect HBV DNA. We investigated the prevalence of occult HBV infection in cirrhotic patients undergoing liver transplantation in a Brazilian referral center. Frozen liver samples from 68 adults were analyzed using a nested polymerase chain reaction assay for HBV DNA. The specificity of the amplified HBV sequences was confirmed by direct sequencing of the amplicons. The patient population comprised 49 (72.1%) males and 19 (27.9%) females with a median age of 53 years (range=18-67 years). Occult HBV infection was diagnosed in three (4.4%) patients. The etiologies of the underlying chronic liver disease in these cases were alcohol abuse, HBV infection, and cryptogenic cirrhosis. Two of the patients with cryptic HBV infection also presented hepatocellular carcinoma. Markers of previous HBV infection were available in two patients with occult HBV infection and were negative in both. In conclusion, using a sensitive nested polymerase chain reaction assay to detect HBV DNA in frozen liver tissue, we found a low prevalence of occult HBV infection in cirrhotic patients undergoing liver transplant, probably due to the low prevalence of HBV infection in our population.

    Introduction: It is known that cytomegalovirus (CMV) infection is a common problem among kidney transplant patients. This infection can be increased morbidity and decreased graft survival. This problem has been associated with acute rejection too. Patients and Methods: One hundred and thirty renal transplant patients were included in a prospective, case-control study. The renal transplant patients were divided into two groups; patients group with CMV infection and control group without CMV infection. Serum CMV-IgG in all patients was positive (donor and recipients). None of patients had received anti-thymocyte-globulin and thymoglobulin. CMV infection was diagnosed by quantitative CMV-PCR (polymerase chain reaction) test (more than 500 copies/μg). Rejection episode was defined by kidney isotope scan or biopsy. Results: In the group of 66 CMV infection patients (41 male [62.1%] and 25 female [37.9%]) the incidence of graft rejection was 36%, however in the group of 64 control patients the incidence of graft rejection was 9.4 % (P < 0.005). Conclusion: CMV infection is important predisposing factor for acute allograft rejection after kidney transplantation. The results of this study suggests that the control of CMV infection could decrease episodes of acute kidney rejection. PMID:27471740

    Diagnosis of infections in cancer patients is usually problematic since differentiating between infection and fever of unknown origin is often a considerable clinical challenge. In general, increase concentration of blood procalcitonin (PCT) is associated with severe bacterial infection. PCT with an optimal cutoff level of 0.5 ng/mL seems to be the most helpful biochemical parameter in detecting severe infections, mainly bloodstream infection, in patients with hematological cancers. In all clinical situations, the elevated level of PCT should be carefully analyzed, always with a thorough physical examination and an appropriate microbiological assessment. PMID:26858528

    Although increasing attention has been paid to the use of dental care by HIV patients, the existing studies do not use probability samples, and no accurate population estimates of use can be made from this work. The intent of the present study was to establish accurate population estimates of the use of dental services by patients under medical care. The study, part of the HIV Cost and Services Utilization Study (HCSUS), created a representative national probability sample, the first of its kind, of HIV-infected adults in medical care. Both bivariate and logistic regressions were conducted, with use of dental care in the preceding 6 months as the dependent variable and demographic, social, behavioral, and disease characteristics as independent variables. Forty-two percent of the sample had seen a dental health professional in the preceding 6 months. The bivariate logits for use of dental care show that African-Americans, those whose exposure to HIV was caused by hemophilia or blood transfusions, persons with less education, and those who were employed were less likely to use dental care (p < 0.05). Sixty-five percent of those with a usual source of care had used dental care in the preceding 6 months. Use was greatest among those obtaining dental care from an AIDS clinic (74%) and lowest among those without a usual source of dental care (12%). We conclude that, in spite of the high rate of oral disease in persons with HIV, many do not use dental care regularly, and that use varies by patient characteristics and availability of a regular source of dental care.

    Aerococcus urinae is an uncommon pathogen that was first identified in 1992. Herein, we report a case of bloodstream infection caused by A. urinae, which occurred in a 92-year-old Korean female patient with an underlying urologic infection who had altered consciousness. The blood culture yielded positive results for A. urinae; however, identifying A. urinae was challenging. Ultimately, we used 16S ribosomal RNA (rRNA) gene sequencing to identify the organism. The patient recovered after being treated with ertapenem and meropenem. To our knowledge, this is the first report of a case of A. urinae sepsis in South Korea. PMID:26868516

    The mean platelet volume (MPV) is a laboratory marker associated with platelet function and activity. Increased MPV in thromboembolic disease is considered an important risk factor. The aim of this study was to compare the MPV and MPV/platelet count (MPV/P) ratio between deep vein thrombosis (DVT) and control subjects. We retrospectively reviewed the medical records of patients (n = 91) admitted due to newly diagnosed DVT from December 2010 to March 2012. The control group (n = 311) underwent health screening at our Hospital. Median MPV was higher in DVT patients compared to controls (8.6 fl vs. 7.9 fl, p < 0.0001). The DVT patients also had a higher MPV/P ratio compared to the control group (0.0388 fl/(10(9)/l) vs. 0.0308 fl/(10(9)/l), p < 0.0001). MPV was inversely correlated with platelet count in DVT patients (correlation coefficient = -0.33, p = 0.001). Receiver operator characteristic analysis revealed that an MPV cutoff value of 8.2 fl provided 70.3% sensitivity and 72.7% specificity. An MPV/P cutoff value of 0.0363 fl/(10(9)/l) showed 60% sensitivity and 73% specificity. MPV and MPV/P ratio could be considered meaningful laboratory markers for the risk of DVT.

    The aim of this study was to investigate the diphtheria-tetanus-pertussis antibody titers after antineoplastic treatment and to suggest an appropriate vaccination approach for pediatric hemato-oncologic patients. A total of 146 children with either malignancy in remission after cessation of therapy or bone marrow failure were recruited. All children had received routine immunization including diphtheria-tetanus-acellular pertussis vaccination before diagnosis of cancer. The serologic immunity to diphtheria, tetanus and pertussis was classified as: completely protective, partially protective, or non-protective. Non-protective serum antibody titer for diphtheria, tetanus and pertussis was detected in 6.2%, 11.6%, and 62.3% of patients, respectively, and partial protective serum antibody titer for diphtheria, tetanus and pertussis was seen in 37%, 28.1%, and 8.9% of patients. There was no significant correlation between the severity of immune defect and age, gender or underlying disease. Revaccination after antineoplastic therapy showed significantly higher levels of antibody for each vaccine antigen. Our data indicates that a large proportion of children lacked protective serum concentrations of antibodies against diphtheria, tetanus, and pertussis. This suggests that reimmunization of these patients is necessary after completion of antineoplastic treatment. Also, prospective studies should be undertaken with the aim of devising a common strategy of revaccination.
