The prolonged disability of patients suffering from chronic fatigue may be due to sustaining factors that are independent of the cause and subject to intervention. This study reexamined a cohort of patients with chronic fatigue to define medical and psychiatric predictors of persistent symptoms. ⋯ At initial examination, patients with chronic fatigue, more than eight medically unexplained physical symptoms (excluding symptoms in the case criteria for CFS), a lifetime history of dysthymic disorder, longer than 1.5 years of chronic fatigue, less than 16 years of formal education, and who were older than 38 years were the most likely to have persistence of symptoms of chronic fatigue at the 2.5-year follow-up.

The aim of the study was to investigate the mechanisms of myocardial catecholamine refractoriness in septic shock. ⋯ An increase in the expression of Gi alpha could also be important in conditions other than chronic heart failure, eg, septic shock. An increase of Gi alpha could play a pathophysiologically relevant role in catecholamine refractoriness in septic shock and could provide a target for pharmacologic treatment in this condition.

The clinical manifestations associated with hyperandrogenism, such as hirsutism and acne, are disturbing to most patients. In addition to correcting androgen-related problems, concerns such as contraception or other metabolic problems (for example, lipid/lipoprotein abnormalities, diabetes, hypertension) associated with these disorders and the effects of unopposed estrogen on the endometrium also need to be considered. Oral contraceptives are a therapeutic modality that may address these multiple problems. ⋯ From a clinical standpoint, 60-100% of women with hirsutism improve on oral contraceptives; acne shows improvement in a high percentage of women as well. The use of oral contraceptives also reduces the risk of endometrial hyperplasia that may be associated with anovulatory states. Finally, current low-dose preparations containing the newer progestins (for example, norgestimate and desogestrel) appear to be either neutral, or perhaps beneficial, with respect to their metabolic impact.
