BACKGROUND: A rapid and sensitive surveillance culture has a pivotal role in infection control of methicillinresistant Staphylococcus aureus (MRSA). This study was aimed to compare the performance of MRSASelect (Bio-Rad, France) to that of mannitol salt agar containing 6 microgram/mL of oxacillin (MSA-OX) for detecting MRSA in surveillance cultures. METHOD: From May to June 2006, 86 nasal swabs and 21 sputum specimens were enrolled. All specimens were inoculated onto MRSASelect and MSA-OX, which were incubated for 2 days and 3 days, respectively, and colonies were read daily by a technologist. Pink colonies on MRSASelect and yellow colonies on MSA-OX were examined with Gram stain, Pastorex(R) Staph-plus (Bio-Rad) and mecA-PCR. After the final reading, both media were re-examined by a superviser. RESULTS: Of the 107 specimens cultured, 32 (29.9%) were positive for MRSA. Of these, 27 were detected by both media, one by MSA-OX only, and 4 by re-examination. The day-1 and day-2 sensitivities/specificities of MRSASelect were 78.1%/97.3% and 84.4%/97.3%, respectively, while those of MSA-OX were 53.1%/100% and 78.1%/92.1%, respectively. With MRSASelect, two more positives were detected at day 2, but their incubation was less than 18 hour at day 1. There were six false positive organisms detected: three Enterobacter spp., one Acinectobacter spp., and two coagulase-negative staphylococci (CNS). But, the two CNS grew on MSA-OX only. CONCLUSION: MRSASelect with 1-day incubation showed a sensitivity equivalent to and a specificity better than MSA-OX with 2-day incubation. MRSASelect should be a useful medium for MRSA surveillance when it is read after an incubation of 18-28 hours with the confirmatory Gram stain of screen-positives.

This study is designed to draw out new integrated subjects of the Korean Oriental Pharmacists' Licensing Examination (KOPLE). In 2004, for the revision of subjects, we have analyzed the curriculums of the Oriental Pharmacy department, the oriental pharmacist's (OP's) job description book, and the elementary items of KOPLE. We also examined the system of the Chinese Herb Pharmacists' Examination and other health personnel licensing examinations and studied the data of items and compared them with KOPLE. We heard the public opinion on the present KOPLE. We developed a subfield of 18 subjects, a middle category of 188 items, and a small category of 1,026 items. We proposed a new KOPLE that consists of three subjects: basic oriental pharmacy, applied oriental pharmacy, and laws and regulations.

Pericardial effusions can be developed by any form of pericarditis; infective pericarditis such as viral or bacterial infection and non-infective, inflammatory pericarditis related with generalized disease such as end-stage renal disease or connective tissue disease and irradiation, postpericardiectomy syndrome, drugs and non-inflammatory pericarditis by malignancy, hypothyroidism, trauma on chest. In children, pericardial effusions are usually related with viral infection, generalized disease or cardiac surgery. We experienced three unusual cases of pericadial effusion by Mycoplasma pneumonia infection, Rickettsia tsutsugamushi infection and post-thoracotomy effusive constrictive pericarditis.

OBJECTIVE: This study was conducted to evaluate the relationship between job stress and quality of life for hospital workers by type of employment. METHODS: Data were obtained for 361 workers in a large hospital 172 of whom were categorized as typical workers defined by permanent employee and 189 of whom were categorized as atypical workers defined by fixed-term contraction. Job stress was assessed using the Korean Occupational Stress Scale-Short Form and the World Health Organization Quality of Life-BREF Questionnaire RESULTS: Atypical workers had significantly higher scores for job-related stress in the domains of insufficient control, over work, job insecurity, and lack of reward in the workplace compared with typical workers, who had higher scores for stress in the domains of job demands and occupational climate. Test scores also indicated that typical workers had a significantly better quality of life than atypical workers, especially in terms of mental health, social relationships and environment. CONCLUSION: These findings suggested that factors contributing to job-related stress were different between typical and atypical hospital and typical workers are likely to have a better quality of life.

BACKGROUND: Procedures for rapid identification and susceptibility testing by direct inoculation (DI) from positive blood culture bottles into an automated system have not been standardized. This study was purposed to evaluate DI from BACTEC 9240 blood culture system (BD, USA) into MicroScan (Dade Behring, USA) or Phoenix (BD, USA). METHODS: From May to June 2006, bacterial pellets from positive aerobic bottles showing gram-positive cocci (GPC) or gram-negative rods (GNR) of single morphology were directly inoculated to MicroScan PosCombo1A and NegCombo32 and to Phoenix PMIC/ID-107 and NMIC/ID-53. In addition, the automated instruments were also inoculated from subcultures (standard inoculations, SI). Species identification and susceptibilities were compared between DI and SI and between MicroScan and Phoenix. RESULTS: A total of 108, 104, and 78 specimens were tested with MicroScan, Phoenix, and both, respectively. When DI and SI were matched, 94.8% of GPC were correctly identified with MicroScan, compared to 80.7% with Phoenix, and 93.9% of GNR were correctly identified with MicroScan, compared to 95.7% with Phoenix. DI with MicroScan and Phoenix showed correct susceptibilities in 94.6% of 1,150 and 96.5% of 660 tests (with very major error [VME] of 1.1% and 1.1%), respectively, among GPC and in 94.4% of 942 and 96.3% of 781 tests (with VME of 0.6% and 0%), respectively, of GNR. Correlation of identification/susceptibilities between MicroScan and Phoenix using DI were 81.8%/98.0% for Staphylococcus aureus and 100.0%/95.6% for Escherichia coli. CONCLUSIONS: DI warrants a reliable method for identification and susceptibility testing of both GPC and GNR in MicroScan, and those of only GNR in Phoenix.

The purpose of this study was to compare food intakes between Korean breast cancer patients and a healthy control group. We compared the intake of nutrients of 117 food items between Korean breast cancer patients (n=97) and age matched healthy controls (n=97). Nutrient intake was estimated using a quantitative food frequency questionnaire. The mean caloric intake of breast cancer patients and healthy controls was not significantly different. Breast cancer patients consumed significantly less fat and antioxidant nutrients such as vitamin A, retinol, beta-carotene, vitamin C and vitamin E when compared to the control subjects. Among the food items, the intake of eggs (p<0.01), legumes (p<0.05), vegetables (p<0.05), seasonings (p<0.001), and oils and fats (p<0.01) in breast cancer patients was significantly lower than that in the controls. These results suggest that Korean breast cancer patients consumed less amount of soy and vegetables, which are rich source of antioxidant nutrients and phytosterols. Thus, dietary guidance to increase intake of these foods may be beneficial in the prevention of breast cancer.

BACKGROUND/AIMS: The individual course of Crohn's disease is diverse, and some patients may require bowel resection. The aims of this study were to determine the early surgery rate of Crohn's disease and to identify risk factors associated with early surgery in Korea. METHODS: Ninety six patients with Crohn's disease (68 men; median age at the time of diagnosis: 25 years), who had been followed up more than a year, were retrospectively analyzed. Early surgery was defined as a bowel operation for Crohn's disease or its complications occurring within 3 years from diagnosis. Early surgery rate and risk factors for early surgery were identified. RESULTS: Fifteen patients (15.6%) underwent early surgery. The cumulative surgery rate was 8.6% after 6 months, 11.9% after 12 months, 14.1% after 18 months, and 16.7% after 24 to 36 months. Multivariate analysis revealed penetrating or stricturing behavior to be an independent risk factor for early surgery (p<0.001, Exp (B)=2.97 CI 1.39-6.37). CONCLUSIONS: The cumulative early surgery rate in Korean patients seems to be lower than Western patients. Penetrating or stricturing behavior is significantly associated with early surgery, requiring early aggressive medical treatments.

Yang Seon RYU ; Chan Hong JEON
Journal of Rheumatic Diseases 2012;19(1):59-62
Radiation recall phenomenon is an inflammatory reaction which occurs at a previously irradiated area after the administration of causative agents, especially anticancer drugs. Radiation recall mostly involves skin and rarely affects internal organs. We, hereby, report a rare case of radiation recall myositis. A 51-years-old man visited the hospital due to pain and weakness of the left thigh. He had been diagnosed with a skin metastasis of pancreatic adenocarcinoma, at the left thigh and treated with radiotherapy and subsequent combination chemotherapy of 5-FU and cisplatin. After the 5th cycle of chemotherapy, the patient developed pain and weakness localized at the previous radiation field. An MRI revealed myositis of left gluteus medius muscle. Muscle biopsy showed no malignant cells or signs of infection. He was diagnosed as having radiation recall myositis and treated with steroid and NSAID. Soon after, pain and weakness gradually improved. Although rare, a possibility of radiation recall myositis should be considered when a patient with history of radiotherapy has a myopathy.

Behcet's disease (BD) is a rare, multisystemic disorder characterized by vasculitis. Although renal involvement rarely coexists with BD, several types of renal involvements have been reported: amyloidosis, glomerulonephritis and vascular involvement. Herein, we report a rare case of BD complicated with IgA nephropathy (IgAN). A 42-year-old woman visited the hospital due to joint pains and painful subcutaneous nodules. Based on her medical history of recurrent orogenital ulcers, arthritis, enteral ulcers, erythema nodosum-like skin lesions, and a positive pathergy test, we diagnosed her with BD. To evaluate proteinuria, we performed a renal biopsy. The patient was diagnosed with BD complicated with IgAN, and treated with a low dosage of steroid, colchicine, as well as angiotensin II type I receptor blockers. Although renal involvement in BD is rare, it is important to periodically perform renal function assessments in patients with BD involving abnormal urine results.
