This letter is in reply to a previous article of April 30 asking if oral contraceptives cause disease of the uterine arteries. The writer has found that changes in the small vessels of the endometrium are an early effect of taking oral contraceptives. Proliferation of endometrial arterioles has been related to headache and migraine incidence. Distended sinusoids have accompanied tiredness and dilated leg veins. Stromal condensation around sinusoids has been found with leg cramps. These changes have preceded thrombosis. It is thought that oral contraceptives cause generalized vascular overactivity. Symptoms are usually rapidly reversible on discontinuing the therapy. At an acute migraine clinic, oral contraceptives and smoking have been important contributing factors in patients requiring emergency treatment. Oral contraceptives are thought to be a more potent cause of bascular disease than smoking.

A patient at 42 weeks of pregnancy called the emergency department complaining of painful uterine contractions for six hours. She was advised to come to the hospital immediately. An episode of vomiting caused a 60-minute delay in her arrival. Dyspnea, fatigue, and leg cramps developed. In the emergency department she was anxious, alert, and cyanotic. Fetal distress was diagnosed. Within 15 minutes the patient had bradycardic cardiopulmonary arrest. Resuscitation attempts and agonal caesarean section failed. Autopsy revealed massive pulmonary amniotic fluid emboli. Amniotic fluid embolus must be considered in the differential diagnosis of pregnant patients with complaints of shortness of breath and signs of shock with bradycardia.

This study investigated the percentage of carbohydrate utilization than can be accounted for by glucose ingested during exercise performed after the ingestion of the potent lipolysis inhibitor Acipimox. Six healthy male volunteers exercised for 3 h on a treadmill at about 45% of their maximal oxygen uptake, 75 min after having ingested 250 mg of Acipimox. After 15-min adaptation to exercise, they ingested either glucose dissolved in water, 50 g at time 0 min and 25 g at time 60 and 120 min (glucose, G) or sweetened water (control, C). Naturally labelled [13C]glucose was used to follow the conversion of the ingested glucose to expired-air CO2. Acipimox inhibited lipolysis in a similar manner in both experimental conditions. This was reflected by an almost complete suppression of the exercise-induced increase in plasma free fatty acid and glycerol and by an almost constant rate of lipid oxidation. Total carbohydrate oxidation evaluated by indirect calorimetry, was similar in both experimental conditions [C, 182, (SEM 21); G, 194 (SEM 16) g.3 h-1], as was lipid oxidation [C, 57 (SEM 6); G, 61 (SEM 3) g.3 h-1]. Exogenous glucose oxidation during exercise G, calculated by the changes in 13C:12C ratio of expired air CO2, averaged 66 (SEM 5) g.3 h-1 (19% of the total energy requirement). Consequently, endogenous carbohydrate utilization was significantly smaller after glucose than after placebo ingestion: 128 (SEM 18) versus 182 (SEM 21) g.3 h-1, respectively (P < 0.05). Symptoms of intense fatigue and leg cramps observed with intake of sweet placebo were absent with glucose ingestion.(ABSTRACT TRUNCATED AT 250 WORDS)

The frequency and severity of physical and emotional menstrual symptoms were investigated with a cross-sectional study of 502 women not seeking treatment for menstrual symptoms. The most frequent symptoms were abdominal bloating, backache, headache, constipation, low abdominal pain, fatigue and symptoms related to depression. Some symptoms increased during the late luteal phase, and others were related to the women's life-style. Lack of schooling and living in rural areas were associated with headache, backache, sadness, insecurity, restlessness and weakness. Women from urban areas with more schooling had more breast tenderness, abdominal pain, irritability, depression, aggressiveness and increased sexual desire. Younger women had increased appetite, lack of concentration, insecurity, desire to be alone, weakness and dissatisfaction with their looks. Heavier women had more leg cramps, swollen feet, lack of coordination and polydipsia. Menstrual symptoms seem to be determined by the interplay of the menstrual cycle with biologic factors and life-style.

In this study perceived well-being and functioning in 28 uraemic patients (14 women and 14 men, mean age 54 years) were measured in the predialysis stage during conservative renal therapy and 3-9 months after having started maintenance dialysis treatment. The patients had participated in a patient education programme in the predialysis stage. Disease-specific symptoms, perceived health (Health Index), functional (SIP) and emotional (STAI) status were analysed. The results showed that there were no significant differences in the patients' correction of uraemia, frequency of symptoms or anxiety prior to and after having started dialysis. After having started dialysis treatment, fatigue, lack of energy and functional disability in work increased while disability in recreation and pastime decreased. Standard bicarbonate correlated significantly to the symptoms of leg cramps and itching. Serum albumin correlated significantly to eating dysfunction in the SIP. There was a large variation within the group with regard to their self-rated disturbances. Some patients reported a relatively intact quality of life, some reported a moderate influence, and some a severe decrease in quality of life irrespective of whether they were in the predialysis state or on maintenance haemodialysis or CAPD. In conclusion, dialysis treatment resulted in increased fatigue and lack of energy, while disease-specific symptoms, functional disability and anxiety did not increase during the first months on dialysis. The symptoms of itching and leg cramps correlated significantly with level of metabolic acidosis, and eating disability correlated with serum albumin levels, indicating that biochemical variables should be combined with patient assessment of health and well-being in order to optimize treatment and care. Moreover, the wide range of scores in all the research variables indicates that assessment of quality of life can be helpful in allocating support to those patients in need of it.

Reactions to oral contraceptive therapy tend to be maximal during the first few months of use. They include nausea or epigastric discomfort, malaise, dizziness, nervousness, fatigue, weakness, leg cramps, headache, and depression. The estrogenic component is thought to be the cause. There may also be a psychogenic basis reflecting apprehension. Breast tenderness is an occasional complaint and intermenstrual spotting or breakthrough bleeding is often reported. Increasing dosage has reduced this symptom. Dysmenorrhea prior to treatment may be improved but occasionally it is aggravated. Drug-induced amenorrhea presents a double problem in that failure to resume medication 7 days after completion of a cycle results in a risk of conception. Episodes of severe uterine bleeding in patients discontinuing use after several months or years have been reported. Other side effects include a skin reaction resembling acne, pruritus, hirsutism, thinning of scalp hair, increased skin pigmentation, and weight gain or loss. Serious vascular complications and hepatic dysfunction have been shown and deviation of thyroid function may be shown by increase of serum protein-bound iodine (PBI). Clinical signs of hyperthyroidism have not been described. Oral contraception is associated with elevated plasma cortisol (hydrocortisone) levels and decreased urinary levels of 17-hydroxycorticosteroids (17-OCHS). Suppression of ovarian activity by oral contraceptives is rapidly reversible. Fear of carcinogenesis has caused much alarm but no proof as of the present time. Safety of long term use will require additional years of experience.

Psychosis only rarely occurs in patients with untreated Parkinson's disease. Much more commonly, psychosis is induced by drug therapy for Parkinson's disease and is the strongest known risk factor for nursing home placement. Delusions are less frequent than hallucinations, but are more concerning as they are often paranoid in nature. Treatment begins with a search for correctable infectious, toxic, and metabolic aetiologies. If symptoms persist, anti-Parkinson's disease medications are slowly reduced. However, withdrawal of these drugs usually worsens parkinsonism and is often not tolerated. Certain atypical antipsychotics can be used to treat psychosis without compromising motor function. The choice of atypical antipsychotic is largely based on ease of use and adverse effect profile as most have comparable efficacy in improving psychosis. Currently, there are five marketed atypical drugs - clozapine, risperidone, olanzapine, quetiapine and ziprasidone. Ziprasidone is the only agent whose adverse effect profile has not been reported in Parkinson's disease. The most common adverse effects of clozapine in Parkinson's disease are sedation, orthostatic hypotension and sialorrhoea. Sedation is generally helpful since these patients are frequently awake at night and tend to have worse behavioural problems then. Clozapine does not induce deterioration of motor function, but it has the potential to cause agranulocytosis, which is idiosyncratic and not dose-related. In risperidone-treated Parkinson's disease patients, reported adverse effects include somnolence, sialorrhoea, dizziness, palpitations, constipation, delirium, fatigue, leg cramps, depression, urinary incontinence and hypotension. Although in some Parkinson's disease studies, risperidone has been well tolerated, others have shown that many patients are unable to tolerate the drug due to deterioration of motor function. While an initial study of olanzapine in Parkinson's disease psychosis showed the drug to be effective without deterioration of motor function, succeeding reports demonstrated a deleterious effect of the drug on motor functioning. The most common adverse effects of quetiapine in Parkinson's disease patients are sedation and orthostatic hypotension. There is a lack of double-blind trials; however, cumulative reports involving >200 Parkinson's disease patients strongly suggest that quetiapine is well tolerated and effective. Unlike clozapine, it does not improve tremor and may induce mild deterioration of motor function. Recently, cholinesterase inhibitors have been reported to alleviate psychosis in Parkinson's disease. Although ondansetron, an antiemetic with antiserotonergic properties, has been reported to relieve psychosis in Parkinson's disease, its prohibitive cost has prevented further study in this population. Electroconvulsive treatment is generally reserved for the patient with psychotic depression who is unable to tolerate any pharmacological therapy.

McArdle's disease is a rare, inherited deficiency of myophosphorylase, an enzyme required for the utilization of glycogen. Patients with myophosphorylase deficiency classically present with exercise intolerance, leg pain and muscle fatigue. The case of a young woman with exertional dyspnea and leg cramps is described. Exercise testing confirmed the presence of exercise intolerance and demonstrated an accelerated heart rate response, despite the absence of an anaerobic threshold and a respiratory exchange ratio of less than 1.0. Subsequent ischemic forearm testing and muscle biopsy confirmed the diagnosis of myophosphorylase deficiency. Evaluation of lung mechanics with esophageal pressure measurements demonstrated the presence of respiratory muscle weakness and early fatiguability, suggesting that the patient's dyspnea might have been attributable to an increased respiratory effort. Dyspnea is not a classic symptom associated with myophosphorylase deficiency, although subclinical respiratory muscle impairment may be present. No previous studies have evaluated respiratory muscle function during exercise in patients with myophosphorylase deficiency.

BACKGROUND: Recent research indicates that sleep disturbances are common in persons with multiple sclerosis (MS), though research to date has primarily focused on the relationship between fatigue and sleep. In order to improve treatment of sleep disorders in MS, a better understanding of other factors that contribute to MS sleep disturbance and use of sleep medications in this population is needed. METHODS: Individuals with MS (N = 473) involved in an ongoing self-report survey study were asked to report on use of over-the-counter and prescription sleep medications. Participants completed the Medical Outcomes Study Sleep (MOSS) scale and other common self-report symptom measures. Multiple regression was used to evaluate factors associated with sleep problems and descriptive statistics were generated to examine use of sleep medications. RESULTS: The mean score on the MOSS scale was 35.9 (standard deviation, 20.2) and 46.8% of the sample had moderate or severe sleep problems. The majority of participants did not use over-the-counter (78%) or prescription (70%) sleep medications. In a regression model variables statistically significantly associated with sleep problems included depression, nighttime leg cramps, younger age, pain, female sex, fatigue, shorter duration of MS, and nocturia. The model explained 45% of the variance in sleep problems. Of the variance explained, depression accounted for the majority of variance in sleep problems (33%), with other variables explaining significantly less variance. CONCLUSIONS: Regression results indicate that fatigue may play a minor role in sleep disturbance in MS and that clinicians should consider the interrelationship between depression and sleep problems when treating either symptom in this population. More research is needed to explore the possibility of under-treatment of sleep disorders in MS and examine the potential effectiveness of nonpharmaceutical treatment options.

Up to 60 percent of adults report that they have had nocturnal leg cramps. The recurrent, painful tightening usually occurs in the calf muscles and can cause severe insomnia. The exact mechanism is unknown, but the cramps are probably caused by muscle fatigue and nerve dysfunction rather than electrolyte or other abnormalities. Nocturnal leg cramps are associated with vascular disease, lumbar canal stenosis, cirrhosis, hemodialysis, pregnancy, and other medical conditions. Medications that are strongly associated with leg cramps include intravenous iron sucrose, conjugated estrogens, raloxifene, naproxen, and teriparatide. A history and physical examination are usually sufficient to differentiate nocturnal leg cramps from other conditions, such as restless legs syndrome, claudication, myositis, and peripheral neuropathy. Laboratory evaluation and specialized testing usually are unnecessary to confirm the diagnosis. Limited evidence supports treating nocturnal leg cramps with exercise and stretching, or with medications such as magnesium, calcium channel blockers, carisoprodol, or vitamin B(12). Quinine is no longer recommended to treat leg cramps.
