Posttraumatic erectile potential of spinal cord injured men: how physiologic recordings supplement subjective reports.

OBJECTIVE: To investigate by means of a neurophysiologic model the remaining erectile function in spinal cord injured men. DESIGN: A nonrandomized control trial. SETTING: A Referred Care Center. SUBJECTS: Forty-seven spinal cord injured men and 7 noninjured controls. INTERVENTION: The subject penile responses were recorded by a penile strain gauge during two sessions--one to obtain baseline responses, and one with reflexogenic stimulation (masturbation) and psychogenic stimulation (film). MEASURES: Average tumescence, maximal tumescence, percentage rigidity, and duration of tumescence and rigidity. RESULTS: Significant results were found for subjects with lower lesions using psychogenic stimulation as their optimal mode compared with reflexogenic stimulation as an alternate mode, and for subjects with higher lesions using reflexogenic stimulation as their optimal mode, compared with psychogenic stimulation as an alternate mode. The responses with optimal stimulation modes were comparable to those achieved by controls. CONCLUSION: The findings validate the neurophysiologic model of posttraumatic erectile potential as a function of the lesion type and stimulation source. The results were comparable to those of noninjured subjects; the potential for normal function is present and may be amenable to sexual rehabilitation or use in conjunction with new oral drug treatments for impotence.

Food habits of French Canadians in Montreal, Quebec.

OBJECTIVES: Since the 1960's, marked sociocultural and economic changes have affected lifestyle, religious practices, and family structure among French Canadians in Quebec. Recent nutritional assessment was unavailable, despite indications of change. METHODS: A survey was carried out in 1988 in a representative sample living in Greater Montreal, to obtain current data on food habits, nutrient intakes and sociodemographic factors, using interviewer-administered questionnaires and seven-day food records. RESULTS: Some 845 families (1450 individuals from different age groups) were studied in two phases: summer/fall and winter/spring. Mean household size in the study population was 2.7. Among adults, extremes of educational level were observed, with 33% having elementary school only and 28% having completed university. On average, each household spent $CAN 89.90 a week for food, $26.00 for tobacco, and $13.50 for alcohol. Breakfast was eaten regularly by 90% of subjects while 96% ate lunch and 99% ate dinner. Morning snacks were consumed by 36% and afternoon snacks were taken by 50%. Milk was consumed with breakfast by 24% of respondents, with lunch by 19%, and with dinner by 24%. On weekdays, 81% of subjects ate their main meals at home, while on weekends this figure was 95%. Time spent for meals varied by meal, and was slightly longer on weekends. Specialty diets, including vegetarianism, were followed by 7% of the study subjects, while 22% adhered to health-related diets. CONCLUSIONS: The food record analyses revealed adequate nutrient intakes overall in relation to the 1990 Canadian Recommended Nutrient Intakes, although further investigation is needed before addressing dietary quality in specific age-sex groups. Protein comprised 16% of energy, fat 38%, and carbohydrates composed 45% or 46% for males and females, respectively. Subsequent analyses will evaluate nutrient intakes in relation to health and sociodemographic indicators in this population.

Patterns of calcium intake among French-Canadians living in Montreal.

In order to determine calcium intake, 1,450 French-Canadians of both sexes, all age groups and various socio-economic status, were recruited in Montreal and Laval using a stratified randomized selection. One thousand and sixty-five (73%) subjects completed food records: 82.4% for a period of seven days, the others for periods varying from one to six days, providing 6,590 days of food records. Subjects ranged in age from one month to 95 years with a mean age of 35.1 years. No seasonal variation in calcium intake was observed. On average, men consumed more calcium than women. This difference was significant for age groups 13 to 15, 19 to 24 and 25 to 49 (p < 0.05). Womens' diets, however, had a higher calcium density than those of men, except among 10-15-year-olds. Mean calcium intake exceeded the RNI for the Canadian population in all age groups except females aged 10 to 15 years, and both men and women aged 50 years and over. The results of this study suggest that those in the study region most at risk for insufficient calcium intake are adolescent females and older men and women.
