OBJECTIVE: Mind-body training (MBT) may control reactions to stress and regulate the nervous and immune systems. The present study was designed to assess the effects of MBT on plasma cytokines and their interactions with catecholamines. METHODS: The study group consisted of 80 subjects who practice MBT and a control group of 62 healthy subjects. Plasma catecholamine (norepinephrine, NE; epinephrine, E; and dopamine, DA) and cytokine (TNF-alpha, IL-6, IFN-gamma, and IL-10) levels were measured, and the differences between the MBT and control groups and the interactions of cytokines with catecholamines were investigated. RESULTS: A significant increase in IL-10+IFN-gamma was found in females of the MBT group compared with controls. Also, a significant increase of IL-10 (anti-inflammatory cytokine) in the MBT group was shown in a specific condition in which TNF-alpha and IL-6 (pro-inflammatory cytokines) are almost absent (≤1 ng/L) compared with controls. In the MBT group, significant positive correlations were found between IL-10 and the NE/E ratio and between IL-10 and the DA/E ratio, whereas the control group did not show any such correlations. CONCLUSION: MBT may increase IL-10, under specific conditions such as a decrease of pro-inflammatory cytokines or E, which may regulate the stress response and possibly contribute to effective and beneficial interactions between the nervous and immune systems.

PURPOSE: This study was conducted to identify the spiritual well-being and spiritual care of hospice team members. METHOD: Between December 2005 and February 2006, a questionnaire was given to 192 hospice team members. The instruments used in this study were the Spiritual Well-Being Scale(SWBS) developed by Paloutzian, & Ellison(1984), and a Spiritual Care Performance Scale developed by the authors. RESULTS: The levels of spiritual well-being were relatively high: significantly lower in the 25-29 years old, in the unmarried, and in the 1-2 million won income groups, and significantly higher in Protestants, Catholics, clergy, and volunteers. The levels of performance of spiritual care were intermediate; significantly higher in clergy, and those with 10 or more years of experience. There was a positive correlation between: levels of spiritual well-being and age; levels of spiritual well-being and performance of spiritual care; and levels of performance of spiritual care and age. The factors affecting the levels of spiritual well-being included religion, age, and performance of spiritual care. The factors affecting the levels of performance of spiritual care were the years of hospice experience and spiritual well-being. CONCLUSION: Because there was a positive correlation between levels of spiritual well-being and performance of spiritual care, there is a need to develop a strategies to increase the spiritual well-being of hospice team members.

Posttransplant lymphoproliferative disorder (PTLD) are among the most serious and potentially fatal complications of chronic immunosuppression in organ transplant recipient and also the most common malignancies, accounting for 21 percent of all malignancies in organ transplants versus 5 percent of malignancies in the general population. PTLD is associated with immunosuppression and Epstein Barr virus (EBV). Treatment modality of PTLD includes antiviral agent, interferon, intensive chemotherapy and monoclonal antibody. Choice of treatment modality depends on clinical presentation of PTLD. We report here a case of PTLD involving liver and renal allograft treated with rituximab.

Giardia intestinalis infections arise primarily from contaminated food or water. Zoonotic transmission is possible, and at least 7 major assemblages including 2 assemblages recovered from humans have been identified. The determination of the genotype of G. intestinalis is useful not only for assessing the correlation of clinical symptoms and genotypes, but also for finding the infection route and its causative agent in epidemiological studies. In this study, methods to identify the genotypes more specifically than the known 2 genotypes recovered from humans have been developed using the intergenic spacer (IGS) region of rDNA. The IGS region contains varying sequences and is thus suitable for comparing isolates once they are classified as the same strain. Genomic DNA was extracted from cysts isolated from the feces of 5 Chinese, 2 Laotians and 2 Koreans infected with G. intestinalis and the trophozoites of WB, K1, and GS strains cultured in the laboratory, respectively. The rDNA containing the IGS region was amplified by PCR and cloned. The nucleotide sequence of the 3' end of IGS region was determined and examined by multiple alignment and phylogenetic analysis. Based on the nucleotide sequence of the IGS region, 13 G. intestinalis isolates were classified to assemblages A and B, and assemblage A was subdivided into A1 and A2. Then, the primers specific to each assemblage were designed, and PCR was performed using those primers. It detected as little as 10 pg of DNA, and the PCR amplified products with the specific length to each assemblage (A1, 176 bp; A2, 261 bp; B, 319 bp) were found. The PCR specific to 3 assemblages of G. intestinalis did not react with other bacteria or protozoans, and it did not react with G. intestinalis isolates obtained from dogs and rats. It was thus confirmed that by applying this PCR method amplifying the IGS region, the detection of G. intestinalis and its genotyping can be determined simultaneously.

Castleman's disease(CD) is rare in childhood. It is defined as a localized nodal hyperplasia in mediastinum or cervical area. It is also called angiofollicular lymph node hyperplasia, lymph nodal hamartoma, giant lymph node hyperplasia. It was first described in 1956 by Castleman et al. as a lesion of mediastinal mass. The etiology of CD is not clear. The histologic classification of CD is hyaline vascular and plasma cell type. The hyaline-vascular type is more frequent, and characterized by small hyaline-folliclees and interfollicular capillary proliferation. The plasme cell type is characterized by the large follicles with intervening sheets of plasma cells. The clinical classification of CD is solitary and multicentric type. The solitary type is usually asymptomatic but, the multicentric type is usually combined systemic manifestations, such as fever, anemia, hyperglobulinemia. Complete surgical resection of involved lymph nodes is both diagnostic and therapeutic. The prognosis of solitary type is good, in a general way. We experienced CD cases in five-year-old girl, who had a 4x3 cm solid mass in postrior triangle of neck, right. The mass was removed completely and confirmed Castleman's disease microscopically. The histopathologic finding was a proliferation of germinal centers with hyaline thickening of the wall and the interfollicular stroma showed hyperplastic vessels admixed with lymphocytes, plasma cells and eosinophils. She discharged after six days of operation and her prognosis was good.

OBJECTIVES: Alcohol consumption is a well-established risk factor for cancer. Despite extensive research into the relationship between alcohol consumption and cancer risk, the effect of light alcohol consumption on cancer risk remains a topic of debate. To contribute to this discourse, we conducted a comprehensive systematic review and meta-analysis. METHODS: Our systematic review aimed to investigate the associations between different levels of alcohol consumption and the risk of several cancer types. We focused on analyzing prospective associations using data from 139 cohort studies. Among them, 106 studies were included in the meta-analysis after a quantitative synthesis. RESULTS: Our analysis did not find a significant association between light alcohol consumption and all-cause cancer risk (relative risk, 1.02; 95% confidence interval, 0.99 to 1.04), but we observed a dose-response relationship. Light alcohol consumption was significantly associated with higher risks of esophageal, colorectal, and breast cancers. Light to moderate drinking was associated with elevated risks of esophageal, colorectal, laryngeal, and breast cancers. Heavy drinking was also found to contribute to the risk of stomach, liver, pancreas, and prostate cancers, thereby increasing the risk of almost all types of cancer. Additionally, females generally had lower cancer risks compared to males. CONCLUSIONS Our findings highlight that cancer risks extend beyond heavy alcohol consumption to include light alcohol consumption as well. These findings suggest that there is no safe level of alcohol consumption associated with cancer risk. Our results underscore the importance of public health interventions addressing alcohol consumption to mitigate cancer risks.

Background: Alcohol consumption is a major risk factor for cancer, and when combined with smoking, the risk increases. Nevertheless, few studies have comprehensively evaluated the combined effects of alcohol consumption and smoking on the risk of various cancer types.Therefore, to assess these effects, we conducted a systematic review and meta-analysis. Methods: We performed a systematic search of five literature databases, focusing on cohort and case-control studies. Considering exposure levels, we quantified the combined effects of alcohol consumption and smoking on cancer risk and assessed multiplicative interaction effects. Results: Of 4,452 studies identified, 24 (4 cohort studies and 20 case-control studies) were included in the meta-analysis. We detected interaction effect of light alcohol and moderate smoking on head and neck cancer risk (relative risk [RR], 4.26; 95% confidence interval [CI], 2.50–7.26; I2 = 65%). A synergistic interaction was observed in heavy alcohol and heavy smoking group (RR, 35.24; 95% CI, 23.17–53.58; I2 = 69%). In more detailed cancer types, the interaction effect of heavy alcohol and heavy smoking was noticeable on oral (RR, 36.42; 95% CI, 24.62–53.87; I2 = 46%) and laryngeal (RR, 38.75; 95% CI, 19.25–78.01; I2 = 69%) cancer risk. Conclusion Our study provided a comprehensive summary of the combined effects of alcohol consumption and smoking on cancers. As their consumption increased, the synergy effect became more pronounced, and the synergy effect was evident especially for head and neck cancer. These findings provide additional evidence for the combined effect of alcohol and smoking in alcohol guidelines for cancer prevention.

BACKGROUND AND OBJECTIVES: The purpose of this study is to evaluate endothelium dependent vasodilation in the diabetic patients suffering with coronary artery disease (CAD). SUBJECTS AND METHODS: 43 patients who presented with typical chest pain and who underwent coronary angiography were enrolled in this study. They were classified into diabetic patients with CAD (n=13), non-diabetic patients with CAD (n=13), diabetic patients without CAD (n=7), and non-diabetic patients without CAD (n=10), according to the presence of CAD and diabetes mellitus. Endothelium-dependent vasodilation of the brachial artery was measured in all the subjects by performing 7.5 MHz high-resolution ultrasound sonography. RESULTS: The endothelium-dependent vasodilation in the diabetic patients with CAD was 1.30+/-2.13% and it was 5.72+/-3.70% in the non-diabetic patients with CAD. There was a significant difference between the two groups (p=0.001). The endothelium-dependent vasodilation in diabetic patients without CAD was 2.28+/-1.88% and it was 10.70+/-10.19% in the non-diabetic patients without CAD. There was a significant difference between the two groups (p=0.029). The endothelium-dependent vasodilations in the diabetic group was 2.28+/-1.88% and it was 10.70+/-10.19% in the non-diabetic group for all the patients. There was a significant difference between the two groups (p=0.029). There was correlation between the endothelium-dependent vasodilation and the fasting blood sugar. There was negative correlation between the endothelium-dependent vasodilation and the fasting blood sugar (FBS) in the patients with CAD (r=-0.59, p=0.002). However, there was no correlation between the endothelium-dependent vasodilation and the FBS in the patients without CAD (r=-0.327, p=0.201). There was negative correlation between the endothelium-dependent vasodilation and the FBS in all subjects (r=-0.352, p=0.021). CONCLUSION: The endothelium-dependent vasodilation was decreased in the diabetic patients with CAD as compared to the non-diabetic patients with CAD. There was also was negative correlation between the endothelium-dependent vasodilation and the FBS in the patients with CAD.

BACKGROUND: The purpose of this study is to investigate the epidemiology and microbiological susceptibility patterns of vancomycin-resistant enterococci (VRE) in Seoul National University Hospital. METHODS: The VRE isolates between May 1998 and October 1999 were studied. We reviewed the medical records of VRE-isolated patients for clinical and epidemiologic data. The susceptibility of VRE to ampicillin, vancomycin, teicoplanin, gentamicin, streptomycin, ciprofloxacin, imipenem, rifampin, tetracyclin were determined by micro-dilution method. PCR for genotyping and PFGE for molecular epidemiology were performed. RESULTS: Twenty-nine VRE isolates were identified from 14 patients, 12 patients from clinical specimens and two from only rectal surveillence cultures. All strains were E. faecium and expressed vanA genotype. The vancomycin MIC and teicoplanin MIC were >128microgram/mL for all isolates. All isolates also resistant to most other antibiotics tested (ampicillin 84.2%, gentamicin 73.7%, streptomycin 73.7%, ciprofloxacin 84.2%, tetracycline 63.2%, rifampin 84.2%, imipenem 94.7%). PFGE analysis revealed 17 distinct PFGE strain types from 14 patients and there were no predominent types. Two patterns, each of them represented by two isolates, were identical. One of which was not associated epidemiologically but the other was associated with direct spread from colonized patient at the intensive care unit. CONCLUSION: The majority of VRE cases occurring at Seoul National University Hospital were not caused by epidemiologic strains but sporadic isolations although there was one case of patient to patient spread.
