The aim of our study was to determine hormonal or biochemical markers in patients with clinically palpable left varicocele but without a history of infertility, with especial emphasis on nitric oxide, related with improved seminal parameters after varicocelectomy. Semen samples were obtained from 202 patients with left varicocele grade II or III. Nitric oxide levels in seminal plasma were determined by the Griess technique. Testicular volume was determined ultrasonographically in both testes and hormonal profile was measured. The post-operative sperm concentration increased significantly in patients with normal sperm count or moderate oligozoospermia, but we did not find an increment in sperm count in patients with mild and severe oligozoospermia after surgery. The mean percentage of normal motility significantly increased after surgery, but we did not observe a significant increment in morphologically normal sperm count and testicular volume after varicocele repair. Moreover, we did not find any correlation between nitric oxide concentrations and severity of oligozoospermia, asthenozoospermia or abnormal sperm morphology in this population. It is concluded that in the general male population, varicocele repair is not associated with an improved semen profile in all cases. We did not observe a significant correlation between nitric oxide concentrations and semen profile.

: A brief questionnaire has been developed to measure behaviour related to dietary fat intake. It is self‐administered and self‐coded. Mean completion time is about three minutes. Criterion validity was assessed by comparison with a well‐established food frequency questionnaire using 124 adults from Newcastle and Sydney. The correlations with the questionnaire scores were: r = 0.55 for total fat as a percentage of total energy, r = 0.67 for saturated fat as a percentage of total energy, and r = 0.44 for polyunsaturated to saturated fat ratio. Reproducibility was assessed by re‐use by 25 subjects after seven to nine months (r = 0.85). When used in a community survey of over 300 randomly chosen people in the Hunter Region, the mean scores for men and for women and among different age groups were significantly different. The questionnaire was strongly associated with other scales measuring attitudes, behaviour and knowledge related to low‐fat diets. The questionnaire appears suitable for rapid self‐assessment by subjects, and as it directs their attention to aspects of their diet which might need improvement, it could be used for health education. It might also be used for epidemiological studies to rank subjects broadly according to their fat‐intake behaviour.

A number of studies report comparisons among ethnic/ racial groups in terms of health attitudes, health practices, and socio-economic and mental health status. Of special concern is the mental health status and coping potential of young women of childbearing age because of the special vulnerability of individuals in this group and the vulnerability of their children. The well-being of future generations is at stake when maladaptive functioning compounded by severe social conditions create a climate for inadequate growth and development for large numbers in a population, even for short periods of time. This paper reports the results of a study examining self concepts and mental health status of two distinct populations within one ethnic group-young Hispanic women living on the U.S. side of the Texas-Mexico border versus a similar sample of young Hispanic women living on the Mexico side. Within each sample, the never-pregnant versus ever-pregnant adolescents were compared. The young women in both groups reported intense feelings related to emotional distress. The young women in Ciudad Juarez reported somewhat more positive feelings related to recent well-being. The El Paso women reported a less traditionally feminine persona (they felt more aggressive, confident, successful, energetic, and successful), yet they experienced less happiness, hopefulness, and life satisfaction. However, neither group could be described as reporting positive mental status and those women who had been pregnant were no different than their never-pregnant counterparts. Rather, the results signal serious problems throughout the two populations. Health care and social service workers must recognize and be prepared to address intense personal distresses in both of these young, Hispanic-female, border populations.

Dietary data were obtained during a community‐based study of risk factors for heart disease in 1983. Results were compared for men and women in broadly defined socioeconomic groups based on occupation and education. People in higher status occupation groups and with more education, and women more than men, had food consumption patterns more consistent with current health promotion messages. For example, they reported eating more wholemeal or brown bread and more fresh fruit and vegetables, drinking more skim or low‐fat milk, eating fewer eggs and having less sugar in hot drinks or on cereals. There was some evidence, however, of an interplay of influences of cost and health awareness. For example, retired men were less likely than employed men to eat butter, cream, fresh fruit and vegetables, while men in the upper socioeconomic groups reported relatively higher consumption of butter and cream. The results emphasise the need for a range of strategies aimed at specific subgroups in order to improve national dietary patterns in Australia.
