Coronary heart disease risk factors in black and white patients with non‐insulin‐dependent diabetes mellitus

Objective. To determine possible racial differences in risk factors for coronary heart disease (CHD) in black and white patients with noninsulin‐dependent diabetes mellitus (NIDDM).

Methods: Study of risk factors for coronary heart disease among 308 subjects who met the WHO criteria for NIDDM.

Results. Both black and white patients were found to have a high prevalence of hypertension, obesity, low high density lipoprotein (HDL) cholesterol, low leisure‐time physical activity levels, and an atherogenic dietary profile. Black males were more likely to have hypertension, reported a greater intake of dietary cholesterol, and had lower triglycerides, higher HDL cholesterol levels, a lower CHOL/HDL ratio, and a lower waist to hip ratio (WHR) than white males. Black females had higher mean arterial and diastolic blood pressures, had lower triglycerides, higher HDL cholesterol, a lower CHOL/HDL ratio, a higher subscapular/triceps ratio and lower reported leisure‐time energy expenditure compared to white females. There were no racial differences found for obesity level.

Conclusion. Our results indicate that racial differences in CHD risk factors exist among black and white patients with NIDDM. The complex genetic, sociocultural and environmental interactions involving CHD risk factors that contribute to the development of CHD may eventually provide clues to the etiology of the disease.     

Insulin-like growth factor (IGF)-I,-II and IGF-binding proteins in the cyst fluid of a patient with astrocytoma

Insulin-like growth factor (IGF)-I,-II and IGF-binding proteins (IGFBPs) were demonstrated in the cyst fluid of a patient with a hypothalamic astrocytoma. The astrocytoma cyst fluid was subjected to gel chromatography at low pH and the IGF-I and IGF-II levels were measured by specific radioimmunoassays. Immunoreactive IGF-I and IGF-II levels were 19 ng/ml and 78 ng/ml respectively. Several-fold higher IGF-II values were obtained when cyst fluid was not extracted or was extracted with acid ethanol before radioimmunoassay analysis. The immunoreactive IGFBP-1 concentration was 26 ng/ml. Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and subsequent Western ligand blotting with [¹²⁵I]IGF-II revealed bands at 200, 34.5, 29.5, 24 and 21 kD as visualized by autoradiography. Binding studies demonstrated that these binding proteins bind specifically [¹²⁵I]IGF-I and [¹²⁵I]IGF-II. These observations suggest that IGFs as well as IGF-binding proteins are produced by astrocytoma cells and may act in a paracrine or autocrine fashion capable of modulating the growth of astrocytoma tumours.     

Psychoeducational groups to teach children sexual abuse prevention skills

A series of studies on sexual abuse prevention are presented to highlight important clinical and research issues. In a multi-modal evaluation conducted by the author, elementary children who participated in three group sessions using the Feeling Yes, Feeling No prevention program increased significantly in knowledge and the ability to discriminate unsafe from safe situations. Gains were maintained over a one-year follow-up period. Approximately 5% of the children disclosed sexually abusive experiences. Participating children also exhibited no more anxiety or behavior problems after the program than control children. A second study evaluated the relative efficacy of prevention programs for children conducted by teachers vs. expert consultants. Children in each trainer condition demonstrated equivalent knowledge gains and made equivalent numbers of disclosures. Clinical research by other authors is reviewed to highlight important issues in prevention groups with preschoolers and adolescents, the impact of prevention education on feelings about sexuality, and behavioral effects of prevention programs. Finally, the incorporation of prevention education into psychotherapeutic groups for child victims is discussed.     

The geographical distribution of multiple sclerosis,rheumatoid arthritis,rheumatic heart disease and poststreptococcal nephritis in Sardinia: Climatic and socioeconomic factors

Summary The comparative geography of multiple sclerosis (MS) and non-neurological diseases considered to be autoimmune is of great interest. But there are few appropriate investigations. Some have found an increase in the frequency of MS, rheumatoid arthritis and rheumatic heart disease depending on the geographic latitude. Nevertheless, the significance of the latitude effect as an indicator of a possible etiological relationship between MS and these conditions has been questioned. In this paper, the frequency of MS, rheumatoid arthritis, rheumatic heart disease and poststreptococcal nephritis is reported from Sardinia where appreciable differences in climatic and socioeconomic conditions exist. There was a positive correlation of the distribution of MS with the distribution of rheumatic heart disease and poststreptococcal nephritis. On the other hand, no correlation was found with the distribution of rheumatoid arthritis.

Zusammenfassung Die Ähnlichkeit zwischen Multipler Sklerose (MS) und nicht neurologischen autoimmunen Erkrankungen veranlassen zur Annahme, daß einige gemeinsame ätiologische Mechanismen im Spiele sein könnten. Das Problem der vergleichenden geographischen Verteilung von Multipler Sklerose und autoimmuner Krankheit ist wenig untersucht. Einige Forscher fanden eine ähnliche Zunahme der Häufigkeit der MS, rheumatoider Arthritis und rheumatischer Herzkrankheiten bei zunehmenden Breitengraden. Es besteht allerdings Zweifel, ob tatsächlich dieser latitude effect als ein wirklicher Indikator von ätiologischen Gemeinsamkeiten zwischen den genannten Krankheiten anzusehen ist. Wir berichten in der vorliegenden Arbeit über die Häufigkeit von MS, rheumatoider Arthritis und rheumatischen Herzkrankheiten sowie Nephritis nach Streptokokkeninfektionen in Sardinien, wo nennenswerte Unterschiede in Bezug auf klimatische und sozioökonomische Gegebenheiten bestehen. Die Verteilung der MS zeigte eine positive Korrelation mit der Verteilung rheumatischer Herzkrankheiten und von Nephritis nach Streptokokkeninfektion. Andererseits wurde keine Korrelation mit der Verteilung der Polyarthritis rheumatica festgestellt.

     

The effects of a subjective monitoring task in the physiological measure of genital response to erotic stimulation

Instrumentation has been developed which promises to further our understanding of the relationship between cognitive and physiological factors in the sexual arousal process. Past research has examined this relationship by continuous measurement of genital response, and discrete posttest measurement of subjective arousal. The self-report or cognitive lever allows individuals to rate feelings of arousal continuously throughout a stimulus interval by positioning a lever device along a calibrated scale. In this way, structural patterns of physiological and cognitive response can be examined. However, since attention has been shown to be an important cognitive operation in the processing of sexual stimuli, there is concern that this subjective measuring task may confound laboratory assessment by altering genital responsivity through distractive or possibly facilitative mechanisms. In order to test the methodological limitations of the cognitive lever, 14 male and female college students were exposed to duplicate viewings of erotic videotapes while alternately using and not using the self-report device. Results indicated that lever usage was not obtrusive in females, but was in males to the point of altering physiological response. In addition, the study took advantage of the continuous, concurrent measurements and examined patterns of convergence and divergence between the two. Results of correlational analyses indicated, in line with past research, that for men greater degrees of erection result in significantly higher subjective-objective agreement. Patterns for women as a group were much less clear, with only two significant correlations appearing. Finally, the limitations of the cognitive lever were discussed.This research was funded in part by VA Merit Review Research Grant 041-34-7119 and NIMH Grant MH33553.     

Posterior approach in cervical spondylotic myeloradiculopathy

Summary Clinical and radiological data are reported concerning 44 patients suffering from cervical spondylotic myeloradiculopathy, and operated by the posterior approach; late results are evaluated.Type of onset, signs and symptoms are specified. Myeloradicular involvement was present in 52% of cases, medullary in 41%, radicular in 7%. Congenital stenosis was present in 68% of patients.Laminectomy was performed at 2–3 levels in 4 cases, at 4 levels in 10 cases, at 5 levels in 14, and extended to 6 or more levels in 16 patients. Posterior foraminotomy was performed 28 times. At follow-up evaluation (6 months to 8 years) results were excellent good in 46% of cases, fair in 34%, unchanged in 9%, and worse in 11%. First symptoms appeared more than 2 years before surgical treatment in 22 patients, between 2 years and 6 months in 15, and less than 6 months before in 7 patients. In this study a statistically significant inverse relation is demonstrated between: 1. results and duration of the disease, 2. results and gravity of motor deficits.     

Psychological characteristics of males with secondary erectile failure

This study was designed to obtain objective data on the personality profiles of two groups of males with a primary complaint of erectile failure and compare them to a group of psychiatric patients unselected for sexual dysfunction and to a sexually normal control group. Utilizing the Eysenck Personality Inventory, the Institute of Personality and Ability Testing Anxiety Scale, Symptom Checklist, and the Minnesota Multiphasic Personality Inventory, it was determined that males applying to a university/county hospital sex-dysfunction clinic appeared similar to patients seen in the same clinic who were unselected for sex dysfunction and more psychologically disturbed than patients with the same complaint applying for treatment at a private clinic. All three groups showed more psychopathology than sexually normal males. The implications of these findings are discussed.
