    Notes: Background: Coronary artery disease (CAD) is associated with a small but measurable amount of electrical disorganization, which may appear as temporal electrical heterogeneity on the electrocardiogram and is not visible with the low resolution, 12-lead electrocardiogram. A newly developed, multilead, high-fidelity variance cardiograph captures the heterogeneity component of the electrocardiograph signal. The subsequent analysis produces an electrical heterogeneity index (EHI) by quantifying phase-invariant electrical disorganization, which represents cardiac abnormalities that are modulated onto the measured high frequency electrocardiogram. A prospective investigation was conducted to determine the predictive accuracy of the variance cardiograph to detect clinically important CAD.Methods: Sixty-five patients (group I) with documented CAD were given the variance cardiography test, as well as 21 normal volunteers (group II). An EHI 〉; 75 from the variance cardiograph was determined to best represent a positive test for clinically important CAD.Results: Group I had a mean EHI of 89.5 ± 19.7, while group II had a mean EHI of 61.1 ± 19.1 (P 〈 0.001). The variance cardiograph had a sensitivity of 79%, a specificity of 76%, a positive predictive value of 91%, and a negative predictive value of 55%.Conclusions: These results demonstrate that analysis of the temporal electrical heterogeneity component of the electrocardiographic signal obtained by the variance cardiograph provides a new and reliable stress-free test For the detection of CAD.

    Notes: Abstract In a house-to-house survey in Ernakulam district, Kerala State, 10914 individuals were interviewed for their tobacco and alcohol habits and examined for the presence of oral leukoplakia. Very few females (1.6%) were found to be alcohol users and they were excluded from further analysis. Among 7604 males, 30.4% used alcohol regularly, 25.4% occasionally and 44.2% were non-users. The prevalence of leukoplakia was significantly higher among regular (5.7%) and occasional (3.9%) users than among non-users (2.9%) of alcohol. Alcohol usage was found to be related to age as well as tobacco habits. The prevalence of leukoplakia was higher among alcohol users in each age-group as well as in each tobacco habit category. After age-adjustment the difference between alcohol users and non-users, although reduced, remained significant. For most tobacco habit categories the trend remained similar after age-adjustment except for the mixed habits group, for which there was a reversal of the trend. The alcohol habit may, perhaps, produce discernible effects only in association with other ‘weak’ etiological risk factors, such as a single tobacco habit of smoking or chewing rather than a ‘strong’ etiologic factor such as the mixed habits of chewing and smoking.

    Inhibition of In Vitro Immune Responses by a Fraction from Seminal Plasma (1976)

    Notes: We studied the inhibitory effects of a fraction of bovine seminal plasma on in vitro lymphocyte responses to specific and nonspecific ligands. Seminal plasma was fractionated by Sephadex G-100 chromatography, and the inhibitory component was found to have a molecular weight of above 100,000 daltons. This fraction was devoid of lymphocytotoxity and could inhibit, in a dose-dependent mode, both the primary antibody response of normal mouse spleen cells to the thymus-dependent antigen sheep erythrocytes and the one-way mixed lymphocyte reactions. Concanavalin A-induced proliferate T-cell responses were also inhibited by the same fraction. The inhibition of the T-lymphocyte responses to Con A was complete at suboptimal concentrations of the mitogen and could only partially be overcome at supraoptimal concentrations. Four other fractions in seminal plasma were also studied in this particular system, three being without effect and one being stimulatory. The inhibitory fraction was also found to inhibit the polyclonal B-cell responses induced by fetal calf serum. The importance of the present findings for the immunophysiology of reproduction are discussed.G.

    Notes: Abstract The prevalence of oral mucosal lesions in Malaysia was determined by examining a representative sample of 11 707 subjects aged 25 years and above throughout the 14 states over a period of 5 months during 1993/1994. A two-stage stratified random sampling was undertaken. A predetermined number of enumeration blocks, the smallest population unit in the census publication was selected from each state. With the selected enumeration block, a systematic sample of living quarters was chosen with a random start. The survey instrument included a questionnaire on sociodemographic characteristics and a clinical examination. The clinical examination was carried out by 16 specially trained dental public health officers and the diagnosis calibrated with a final concordance rate of 92%. The age in the sample ranged from 25 to 115 years with a mean of 44.5+14.0. The sample comprised 40.2% males and 59.8% females; 55.8%. were Malays, 29.4% Chinese,10.0% Indians and 1.2% other ethnic groups. Oral mucosal lesions were detected in 1131 (9.7%.) subjects. 5 (0.04%) had oral cancer, 165 (1.4%) had lesions or conditions that may be precancerous (leukoplakia. erythroplakia, submucous fibrosis and lichen planus) and 187 (1.6%) had betel chewer's mucosa. The prevalence of oral precancer was highest amongst Indians (4.0%) and other Bumiputras (the indigenous people of Sabah and Sarawak) (2.5%) while the lowest prevalence was amongst the Chinese (0.5%).

    Notes: Oral cancer is caused by chewing and smoking of tobacco. To assess the feasibility of primary prevention of oral cancer, two cohorts were studied in base-line surveys and then followed up annually for 10-yr in Ernakulam district of Kerala state. The intervention cohort consisted of 12212 tobacco users aged 15 yr and over, who were exposed to a concentrated program of eduction against tobacco use. The control cohort was a non-concurrent cohort of 6075 tobacco users studied using similar methods but with a minimal amount of advice against tobacco use. The stoppage of tobacco use increased and the incidence rate of leukoplakia decreased significantly and substantially in the intervention cohort compared to the control cohort. The decrease in the incidence of leukoplakia was indicative of the decrease in the risk of oral cancer since the two were intimately related. This study demonstrated feasibility of primary prevention of oral cancer.

    Leukoplakia and incidence of oral cancer (1989)

    Notes: Reports from India showing comparatively lower prevalence rates of oral leukoplakia and lower malignant transformation rates than in western countries appear paradoxical because of high incidence rates of oral cancer in India. On a closer examination of available data however, it becomes clear that there is no inconsistency.
