PMS is probably a group of entities which include various symptoms that occur during the 7 to 10 days before menstruation and disappear a few hours after the onset of menstruation. The definition of PMS lacks objective criteria. The most common symptoms are irritability, bloating, aggressiveness, mastodynia, and headaches. The prevalence of PMS is estimated at 30 to 40 per cent. PMS is more prevalent among women working outside the home, alcoholics, women of high parity, and women with toxemic tendency; it probably runs in families. The etiology of PMS is no less obscure to us than when it was first described by Frank in 1931. No single theory has been established to explain the entire diversity of PMS symptomatology. The multitude of possible etiologic factors includes psychosocial bases, progesterone deficiency, prolactin excess, thyroid hypofunction, renin angiotensin alternations, antidiuretic hormone excess, decreased colloidosmotic pressure, endorphin activity alternations, serotonin metabolism alternations, prostaglandin action, vitamin deficiency, and such unconventional theories as the ovarian infection or the "yeast overgrowth" theory. A partial resolution of this divergence of hypotheses comes from the biopsychosocial model developed by Keye and Trunnel. According to this model, a biologic, perhaps genetically determined, predisposition to PMS is realized when past and present life experiences, attitudes, beliefs, coping styles, and social forces interact to stress a woman. The diagnosis of PMS is based on establishing a relationship between the luteal phase of the cycle and the symptoms. The evaluation of PMS patients includes the use of a monthly diary to scale the symptoms, a physical examination, and biochemical studies to rule out other disorders. Management includes education, reassurance, and drug therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

The effectiveness of pulsed high-dose oral dexamethasone therapy in children with refractory chronic idiopathic thrombocytopenic purpura (ITP) is evaluated. Thirteen children with severe chronic ITP were enrolled in the study from an outpatient pediatric hematology clinic (ages 2-14 years), 5 boys and 7 girls. They did not maintain a response to other forms of therapy (IVIg, Anti-D, conventional steroids, danazol) and one girl relapsed after splenectomy. Dexamethasone was administered orally at a dosage of 40 mg/M2/day (maximum 40 mg/day) for 4 consecutive days. The cycle was repeated once a month for 6 months. The immediate response to therapy was excellent as the mean platelet count at day 1 was 15 x 10(9)/L, while mean platelet count at day 4 was 158 x 10(9)/L. At the end of 6 cycles 3 patients maintained a platelet count of >150 x 10(9)/L and 4 patients showed partial response. At the end of the first year and second year (12 and 24 months after onset of treatment) 3 patients still had complete response, 3 patients had partial response, and 7 patients were failures. Six of the failures underwent splenectomy and one was shifted to dapsone, had no response, and refused splenectomy. Side effects were tolerable. They included bloating, nausea, vomiting, insomnia, anxiety, and depression, and transient glucosuria; however, they were not severe enough to discontinue the cycles. Mean duration of illness prior to start of dexamethasone was not significantly different in between responders and nonresponders. Dexamethasone given orally in high doses is an effective drug in achieving short-term platelet responses. Long-term remission is obtained in nearly half the patients with well-established chronic ITP. Its effectiveness in almost half the patients, minimal side effects, and low cost indicate that this treatment should be considered in patients with chronic ITP who do not tolerate the disease well before considering splenectomy.
