Some religious rites of Hajj (the obligatory pilgrimage that many Muslims make to Mecca) cannot be performed during menstruation, so women may wish to suppress their menses. Eliminating monthly periods could further improve the quality of women’s lives, reducing both physical pain and mood swings that can be disruptive or debilitating, to say nothing of the inconvenience and cost of managing mo...

Menorrhagia, defined clinically as menstrual blood loss in excess of 80 ml per cycle, is a common gynaecological complaint that presents both to primary and secondary care. The aim of this review of the literature is to discuss current opinion in the investigation and management of menorrhagia. As menorrhagia is a subjective condition that is difficult and impractical to assess objectively, thi...

OBJECTIVE To evaluate menstrual cycle histories among women with type 1 diabetes, their sisters, and unrelated control subjects without diabetes across all reproductive ages. RESEARCH DESIGN AND METHODS Menstrual and reproductive histories were obtained by questionnaire from 143 women with type 1 diabetes, 186 sisters without diabetes, and 158 unrelated control subjects without diabetes parti...

Standard microeconomic theory proves that, when a externality occurs, the solution of the social cost problem requires that the producers face an additional cost identical to the marginal damage caused by them at the efficient level of the externality. Pigouvian taxes, and adequately designed property rights markets, are both political instruments to put this theory into practice. Nevertheless,...

The acute effects of luteinizing hormone releasing hormone (LHRH) on the release of prolactin (PRL) were investigated in 12 normal cycling women and 42 women with various menstrual disorders. LHRH (100 micrograms) was bolusly injected intramuscularly and PRL levels were measured immediately before the injection and at 30 minutes and 60 minutes after the injection. LHRH elicited an increase of m...

Research on parental depression is beginning to recognize the importance of studying fathers in relation to maladaptive outcomes in their offspring. Paternal depression is hypothesized to correlate with internalizing and externalizing psychopathology in children and adolescents and to compromise adaptive parent-child relationships (e.g., increased conflict). In the present paper, meta-analytic ...

BACKGROUND It is well documented that friends' externalizing problems and negative parent-child interactions predict externalizing problems in adolescence, but relatively little is known about the role of siblings. This four-wave, multi-informant study investigated linkages of siblings' externalizing problems and sibling-adolescent negative interactions on adolescents' externalizing problems, w...

Recent discoveries stress the importance of studying positive emotion disturbances (PED) yet there remains little empirical work or integrative conceptual framework in this domain. We suggest that an ideally suited opportunity to advance the study of PED is to consider a cross-species evolutionary framework. We apply this framework—drawing from principles of stabilizing selection—to recent empi...
