Recent expansion of biomedical knowledge on the interactions between the
fetus, placenta, and the mother have transformed our view of pregnancy in
general. Recent basic and clinical investigations have improved significantly our
understanding on how hormones affect the pregnancy, and on how pregnancy
affects the fetal and maternal hormones. Because pregnancy may be seen as the
ultimate hormonally mediated event, the topic of endocrinology of pregnancy is
Sexual dysfunction is one of the most common conditions seen in a
primary care provider’s office. Large surveys indicate that one fourth or
more of patients report sexual distress or dysfunction. Yet the diagnosis is
rarely made, even though most patients who have a sexual problem report
that they wish their physician would ask about it.
Why do physicians not uncover sexual problems? Many physicians state
that they do not know what to do when they uncover a sexual problem.
Medical advances have been occurring at breathtaking speed, with diagnostic and treatment
options becoming available for conditions for which none previously existed. However, several
aspects of health care remain the same. Patients continue to rely heavily on clinicians for help in
understanding the burgeoning evidence in medical research and for providing optimal health
care. Clinicians remain steadfast in their quest to meet the needs of their patients and to encourage
innovation in meeting those needs.
This study was motivated by a conflict between the nonproliferation
objectives of the Energy Policy Act of 1992, which created increasing
pressures to phase out U.S. exports of highly enriched uranium
(HEU) for medical isotope production, and the Energy Policy Act of 2005,
which sought to increase the reliability of medical isotope supply by lifting
the requirements of the 1992 Act for HEU exports to Canada, the
Belgium, France, and Germany for medical isotope production.
