PURPOSE: The purpose of this study was to review articles related to the psychometric properties of the Perceived Stress Scale (PSS). METHODS: Systematic literature searches of computerized databases were performed to identify articles on psychometric evaluation of the PSS. RESULTS: The search finally identified 19 articles. Internal consistency reliability, factorial validity, and hypothesis validity of the PSS were well reported. However, the test-retest reliability and criterion validity were relatively rarely evaluated. In general, the psychometric properties of the 10-item PSS were found to be superior to those of the 14-item PSS, while those of the 4-item scale fared the worst. The psychometric properties of the PSS have been evaluated empirically mostly using populations of college students or workers. CONCLUSION: Overall, the PSS is an easy-to-use questionnaire with established acceptable psychometric properties. However, future studies should evaluate these psychometric properties in greater depth, and validate the scale using diverse populations.

One case of Incontinentia pigmenti associated with convulsion has been presented and she has delayed growing and emerciation. The patient who was four months old girl had been affected irregular mesh-like dark brown or chocolate colored pigmentation on both leg (inner surfeee). Diagnosis was confirmed by characteristic clinical appearance, laboratory findings and histopathology.

BACKGROUND AND OBJECTIVES: Coronary collateral circulation is known to have beneficial effects in patients with angina pectoris and myocardial infarction. The purpose of this study is to determine the predictors of collateral vessels development, the pathways of collateral circulation and the changes in collateral flow after coronary intervention and its functional significance in patients with total occlusion. MATERIALS AND METHODS: One hundred thirty five patients who underwent coronary angiogram between Jan '97 and Dec '97 in Chonnam University Hospital (out of 3,264 cases) had total occlusion of one coronary artery were classified into two groups: angina pectoris (Group I:50 M, 19 F, 62.4+/-11.0 years) and acute myocardial infarction (Group II: 47 M, 19 F, 62.0+/-9.5 years). RESULTS: Among 135 patients, 123 patients had collateral circulation. Collaterals were more frequently observed and better developed (grade 2 or 3) in Group I than Group II. Proximal and ostial lesions were associated with well developed collaterals. Collateral circulation was more frequently observed and well developed in proportion to the duration of angina in Group I. In 123 patients with collateral circulation, 247 collateral circulations were observed. Right coronary artery (RCA) and Left circumflex coronary artery (LCX) were more frequent recipient arteries than left anterior descending coronary artery (LAD)(RCA:2.20+/-1.02, LCX:1.88+/-0.94, LAD:1.29+/-0.8 respectively, RCA vs. LAD:p<0.001, LCX vs. LAD:p=0.014). Coronary interventions were performed in 50 out of 135 patients, collateral flow of Group II decreased much more than Group I after intervention (Group I: 5/14, Group II: 24/36, p=0.046). The wall motion score was lower in patients with well developed than poorly developed collaterals (20.7+/-4.91 vs. 23.7+/-6.22, p=0.015). CONCLUSION: Proximal or ostial lesion and duration of angina are major predictive factors for the development of collateral circulation. Collateral circulation is associated with preserved myocardial contractility.After coronary intervention in patients with acute myocardial infarction, recruitment of preexisting collaterals may be more important mechanism rather than neoangiogenesis.

One case of tuberculosis verrucosa cutis associated with inguinal lymphnode enlargement is presented. The patient, 24 years old male, has had palm-sized, dark-brown colored, indurated verrucous patch on left buttoek since 12 years old. Diagnosis was confirmed by characteristic clinical appearance, laboratory findings and histopathology. So he has been treated with I.N.A.H., P.A.S., streptomycin and pyridoxine. Remarkable effect was observed.

BACKGROUND: The purpose of this study was to assess the prevalence of orthostatic hypotension(OH) and its associations with demographic characteristics, body mass index, medications, disease and activities of daily living. METHODS: Orthostatic hypotension was assessed at 1 minutes after the patients arose from a supine position among the 183 elderly patients aged 60 years or older in a mental hospital. RESULTS: The prevalence of orthostatic hypotension defined by changes in systolic or diastolic blood pressure was 41.0% and the prevalence of systolicorthostatic hypotension was 13.1%. Body mass index and serum sodium concentration were lower in women with orthostatic hypotension than those without orthostatic hypotension, but there were no differences among men. Orthostatic hypotension was significantly associated with the level of supine systolic and diastolic blood pressure. Through multiple logistic regression analysis, orthostatic hypotension seerned to be associated with factors such as body mass index, supine diastolic blood pressure and serum sodium concentration. There was no association between orthostatic hypotension and factors such as sex, age and medications. CONCLUSIONS: Orthostatic hypotension was common in the long-term hospitalized elderly patients. It was associated with hypertension, hyponatremia and low body weight.
