Sexual dysfunction is a common problem for patients with cancer as well as cancer survivors. Unfortunately, sexual difficulties are often not identified by the cancer care team, and most patients receive little or no assistance in dealing with the effects of cancer and its treatment on intimacy. In this article, recommendations concerning assessment of sexual function are presented and various treatments are reviewed. The authors recommend that questions concerning sexual difficulties and intimacy be incorporated into the initial evaluation of patients with cancer. The assessment of sexual difficulties should continue throughout treatment and recovery. The cancer care team can initiate interventions including patient education and treatments for altered desire, erectile dysfunction, and estrogen deficiency. These interventions may result in marked improvement in symptoms. Some forms of sexual dysfunction may require referral to a specialist. Based on their experience, the authors conclude that assessment and treatment of sexual dysfunction in patients with cancer should become standard practice, and that quality of life is enhanced when attention to the sexual consequences of cancer and its treatment are addressed.
A procedure was developed for the analysis of estrogens in environmental water and effluents. Samples were extracted by passing through polymer-impregnated solid-phase extraction discs or C18 cartridges, followed by gas chromatography-negative chemical ionisation mass spectrometry of the pentafluorobenzoyl derivatives. The derivatives were stable and gave diagnostic negative molecular ions as the base peak for each of the major estrogens studied. The absolute recovery of estrogens spiked into clean groundwater using the disc procedure was 84-116% at the 10 ng l(-1) level (calculation not based on use of internal standards). Using doubly deuterated estradiol as internal standard added prior to extraction, the % relative standard deviation of estrogen extraction and analysis in spiked groundwater at the 10 ng(-1) level was 2.6-9.8%. Detection limits were 0.2 ng l(-1) or below for the major estrogens, based on a 2.5 litre sample. The most abundant estrogen was estrone, with concentrations over the range 6.4-29 ng l(-1) in effluents, and 0.2 to 17 ng l(-1) in water from the River Thames.
