BACKGROUND: The safety of ergonovine provocation for coronary vasospasm (CVS) performed outside the catheterization laboratory has been questioned. We sought to address the issues of safety, feasibility and clinical impact of noninvasive diagnosis of CVS. METHOD AND RESULTS: We retrospectively analyzed the results of bedside ergonovine provocation testing with monitoring of left ventricular regional wall motion abnormalities (RWMAs) by 2-dimensional echocardiography (ergonovine echocardiography, Erg Echo). After confirmation of no significant fixed epicardial coronary artery disease, 1,504 Erg Echo were performed in 1,372 patients from July 1991 to December 1997. Erg Echo was prematurely terminated in 13 patients (0.9%) due to limiting side effects unrelated with myocardial ischemia. Among 1,491 completed tests, 32% (477) showed positive results with development of RWMAs in 467 tests (98%) or ST displacement in ECG in 10 tests (2%). During the test, transient arrhythmias developed in 1.7% (26/1491) including transient ventricular tachycardia (2) and atrioventricular block (4), which were promptly reversed with nitroglycerin. There were no procedure-related death or development of myocardial infarction. On the basis of angiographic criteria in 218 patients, who also underwent invasive spasm provocation test during coronary angiography, the sensitivity and specificity of Erg Echo for the diagnosis of CVS were 93% and 91% respectively. From 1990 to 1997, total 2,073 spasm provocation tests were performed either during invasive coronary angiography in the catheterization or in the echocardiography laboratory. Since 1994, noninvasive Erg Echo became a more popular diagnostic method and comprised more than 95% of all spasm provocation tests in recent 3 years. Erg Echo was also performed safely in outpatient clinic setting without hospital admission in 34% (500/1491). CONCLUSIONS: Erg Echo is highly feasible, accurate and safe for diagnosis of CVS and can replace the invasive spasm provocation test during coronary angiography in the catheterization laboratory.

OBJECTS: Thls study was designed to assess muscle tensions while working at a YDT workstation with surface electromyography (SEMG). METHODS: Variables texted were desk height, monitor positon on the desk, distance from edge of the desk to the keyboard. Eleven female volunteers working in the tele-com munication company were seated at an ergonomically adjusted workstation. They were assigned to a task of typing for 5 minutes and were given a 10 minutes resting with hands in their lap. For the initial experiment, the desk height was fixed to standard desk height(65.0 cm) recommended by ANSI and latter adjusted to a higher desk height (72.8 cm) for this study such that the subjects experienced slight elevation of shoulders. The monitor position initially at the center on the desk and latter left site of the desk (45o from monitorneck axles). The keyboard was positioned to an optimal distance (15 cm from the desk edge) and an abnormal distance (30 cm). Five muscle groups (paraspinal muscles, upper trapezium muscle, supraspinatus muscle, infraspinatus muscle, and rhomboid muscle) were selected for the study. The data of SEMG were analyzed by 2x2x2xs mixed factorial design. RESULTS: The results were as follows: 1. SEMG activity recorded from the paraspinal muscles were significantly higher when the angle of the monitor adjusted to 45 degree from the center of the desk.. 2. SEMG activity recorded from the upper trapezius/supraspinatus/infraspinatus muscles were significantly higher when the hight of the desk was elevated from the recommended height.3. SEMG activity from the rhomboid muscle showed no significantiy difference in all test conditions. CONCLUSIONS: The results of thls study confirm that the helght of a VDT workstation and the angle of the monitor are risk factors of upper extremity cumulative trauma disorders. Also SEMG would be useful for measuring muscle activities during workstation assessment.

BACKGROUND: The skin of patients with atopic dermatitis (AD) exhibits a striking susceptibility to colonization with Staphylococcus aureus (S. aureus). Superantigens produced by S. aureus and their specific IgE antibodies are thought to be important precipitating factors of AD, but there are few reports evaluating these 2 factors at the same time, particularly in adult AD patients. OBJECTS: Our purpose was to investigate the differences in the culture degree of S. aureus from the lesion, non-lesion, and control group of child and adult AD patients, to research the correlation between the exotoxin production, total IgE, anti-SEA IgE and the disease severity by SCORAD index, to ascertain the differences between child and adult AD patients. METHODS: The clinical severity of 30 child (2 to 15 years of age) and 30 adult patients (16 to 40 years of age) with AD was evaluated by using SCORAD index. S. aureus was isolated from lesional and non-lesional skin of AD patients, and from healthy controls. Staphylococcal exotoxins were detected by using reversed passive latex agglutination toxin detection kits. Anti-SEA IgE antibody was determined by using AlaSTATt assay RESULTS: S. aureus colonizations were found in 11 (36.7%) of the lesional skin, in 5 (16.7%) of the non-lesional skin of 30 child AD patients, and in 26 (86.7%), in 20 (66.7%) of 30 adult AD patients, respectively. The colonization rates of S. aureus in child patients were much lower than those in adult patients, both form lesional skin and non-lesional skin. Staphylococcal exotoxins were detected in 5 (45.5%) of the 11 colonizations from lesional skin, in 2 (40%) of the 5 colonizations from non-lesional skin of children, and in 10 (38.5%) of the 26 colonizations, in 9 (45%) of the 20 colonizations of adults, respectively. Staphylococcal enterotoxin A (SEA) was most frequently detected in both groups. S. aureus colonization was correlated with the severity of AD in childhood, but not in adulthood. However, there were no statistical significances between severity of AD and others such as exotoxin production, and the level of total IgE and anti-SEA IgE in both groups. CONCLUSION: The colonization of S. aureus was more common in adult AD patients than child AD patients. Anti-SEA IgE level was much higher in adult AD patients than in child AD patients. It is tempting to speculate that the colonization of S. aureus and exotoxin production might be related to the disease. duration rather than clinical severity of AD.

The onset of systemic scleroderma in the first. decade of lif occurs in less than 1.5% of instances. Systemic sclerodrma in childhood have been characterized by less severe visceral involvement and a benign course We report a boy, aged 7 years, with a history of Raynaid; phenomenon and dysphagia. He had a mask-like face, flexion contracture of hands and knee joints, digital pitting scars, ichthyosiform skin change on leg and hyperpigrnented induration on all extremities and trunk. Antinuclear antibodies were positive in nucleolar type and Scl-70 antiocy was also present. On radiologie study, the pattern of reflux esophagitis and resorption of the listal ends of all phalanges were nated. Histopathological findings were compatible with sclerodma. He was treated with Penicillamine-D and oral corticosteroic with good improvernent.

Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.
