Recently, a series of 5-HT7 receptor antagonists have been developed (24,29,36,68). Among them SB-258741, R-(+)-1-(toluene-3-sulfonyl)-2-[2-(4-methylpiperidin-1-yl)ethyl]-pyrrolidine, (compound "13" in 36,37) was one of the most potent and specific compounds. Due to a lack of specific ligands the pharmacology of 5-HT7 receptor antagonists is still relatively unexplored. It has been suggested, however, that 5-HT7 receptor ligands could be useful in the therapy of various disorders such as sleep disorders, schizophrenia, depression, migraine, epilepsy, pain, or memory impairment. Many of these conceivable indications are not supported by pharmacological data. It is, therefore, of particular interest to review the data generated from studies of one of these most potent and specific 5-HT7 receptor antagonists, SB-258741, with a goal of testing the validity of the proposed clinical indications. In this review, the author describes pharmacology of this compound in order to define its potential clinical use. The available safety pharmacology data are discussed in an attempt to predict potential side effects of specific 5-HT7 receptor antagonists.

In summary, the treatment of patients with FM requires a proper assessment of the reason for the unrefreshing sleep, which is an important component of the FM syndrome. Sleep laboratory investigations provides a suitable rationale for management where a specific primary sleep disorder is determined. Nonspecific treatments include various behavioral approaches to improve sleep hygiene, fitness, and regular proper nutrition that serve to regularize disturbances in circadian sleep-wake rhythms. As yet, no medication is known to improve the EEG sleep arousal disorders that include phasic (alpha-delta), tonic alpha non-REM sleep disorders, or the periodic K alpha cycling alternating pattern disorder. Traditional hypnotic agents, while helpful in initiating and maintaining sleep and reducing daytime tiredness, do not provide restorative sleep or reduce pain. Tricyclic drugs, such as amitriptyline and cyclobenzaprine, may provide long term benefit for improving sleep but may not have a continuing benefit beyond one month for reducing pain. The use of a biologic agent that facilitates sleep-related neuroendocrine functions, for example growth hormone, is reported to improve symptoms but the need for injection and high cost restrict its use. No systematic studies have been reported on the use of remedial measures for the management of PLMS/restless legs syndrome and sleep apnea that occur in some patients with FM.

239 women, who constituted 61% of the 389 undergoing sterilization operations in a Geneva maternity hospital in 1977, were interviewed by telephone 18 months-2 years later to assess the occurrence of psychosexual side effects. 20% reported gaining more than 3 kg; 10% experienced psychological trouble manifested in irritability, depression, or sleep disorders; 15% reported a persistent desire for a child or pregnancy; 1/3 reported an improved sexual adjustment; 10% reported a deterioration; and 7% reported experiencing pain during intercourse. 20% were under 30 years old at the time of the operation but they did not experience a higher rate of side effects than the older women. Women without any children, women from lower socioeconomic levels, and immigrant women expressed higher degrees of regret. Women exposed to religious opposition to sterilization, all of whom were practicing Catholics, were more likely to experience psychosexual side effects. Negative repercussions were also more common when the decision was made on medical grounds rather than as a personal choice by the woman, and when the procedure immediately followed abortion or childbirth. 16% felt that they had received insufficient medical information prior to the procedure. The experience of regret at not having another child and desire for another pregnancy were less when women who had themselves undergone the operation were involved in counseling.

The objective was to compare the prevalence and severity of fatigue in patients with Parkinson's disease (PD) with that in two control groups, one consisting of randomly chosen control subjects of the same age and sex distribution and the other consisting of patients with coxarthrosis waiting to receive total hip replacement. We also explored the possible correlation of demographic and clinical data to the presence and severity of fatigue. Sixty-six patients with PD, 131 randomly chosen controls and 79 patients with coxarthrosis, waiting to receive total hip replacement, were evaluated for fatigue. Patients and controls with a depressive mood disorder or cognitive impairment had been excluded from the study. Fatigue was measured by the Fatigue Severity Scale (FSS). For the patients with PD the mean total FSS score was 4.1, compared with 2.7 amongst the randomly chosen control group and 2.9 in the group consisting of patients with coxarthrosis. Fifty per cent of the patients with PD had a mean total FSS score of 4 or higher, compared with 25% in both of the two control groups. There was no correlation between pain, presence of self-reported nocturnal sleep disorders or duration of PD and fatigue. The patients with fatigue did have a more advanced disease, measured both by Unified Parkinson's Disease Rating Scale score and Hoehn and Yahr stage. Although the univariate analyses indicated that more severe parkinsonism was correlated to the symptom, the multivariate analysis showed that none of the studied variables were significant explanatory factors for fatigue. Fatigue is a common symptom in patients with PD without depression or dementia. The study indicates that fatigue is an independent symptom of the disease without relation to other motor or non-motor symptoms.

Noxious stimuli and painful disorders interfere with sleep, but disturbances in sleep also contribute to the experience of pain.Chronic paroxysmal hemicrania and possibly cluster headaches are related to REM sleep. Whereas headache is associated with snoring and sleep apnea, morning headaches are not specific for any primary sleep disorder. Nevertheless, the management of the sleep disorder ameliorates both morning headache and migraine.Noxious stimuli administered into muscles during slow-wave sleep (SWS) result in decreases in delta and sigma but an increase in alpha and beta EEG frequencies during sleep. Noise stimuli that disrupt SWS result in unrefreshing sleep, diffuse musculoskeletal pain, tenderness, and fatigue in normal healthy subjects. Such symptoms accompany alpha EEG sleep patterns that often occur in patients with fibromyalgia. The alpha EEG patterns include phasic and tonic alpha EEG sleep as well as periodic K alpha EEG sleep or frequent periodic cyclical alternating pattern. Moreover, alpha EEG sleep, as well as sleep-related breathing disorder and periodic limb movement disorder, occur in some patients with fibromyalgia, rheumatoid arthritis and osteoarthritis. Depression and not alpha EEG sleep are features of somatoform pain disorder. Disturbances in sleep, pain behaviour and psychological distress influence return to work in workers who have suffered a soft tissue injury, e.g. low back pain. Patients with irritable bowel disorder have disturbed sleep and have increased REM sleep. In conclusion, there is a reciprocal relationship between sleep quality and pain. The recognition of disturbed or unrefreshing sleep influences the management of painful medical disorders.

Cluster headaches are characterized by unilateral paroxysmal attacks of severe pain with associated symptoms. The headaches occur during particular sleep stages and are associated with other chronobiologic factors. Several sleep disorders have been associated with the occurrence of cluster headache; multiple hormonal influences affect the relationship between sleep and headache. Melatonin and other treatments that affect circadian rhythm have been suggested for the treatment of cluster headache. Obstructive sleep apnea can occur in patients with cluster headache; attempts to treat one disorder may influence the other. Sleep disorders such as insomnia and narcolepsy also may be associated with and influence cluster headaches. This article examines the relationship between the various sleep disorders and cluster headache, and reviews current research. Normal and abnormal sleep and details of treatments for specific sleep disorders that may decrease the frequency and severity of cluster headaches also are discussed. The relationship between obstructive sleep apnea, which is the most common sleep disorder, and cluster headache is discussed in detail.

The relationship between sleep and sleep disorders and headache remains unclear. Clinical experience and numerous studies document some sort of relationship, but the exact nature remains understudied and complex. Changes in sleep duration and sleep quality appear to be capable of affecting headaches of different types. Obstructive sleep apnea can cause or exacerbate headaches in a susceptible person. Obstructive sleep apnea also may cause a specific headache when awakening, which is different from migraine or tension headache and disappears after treatment of the sleep and breathing disturbance. Hypnic headache is another type of sleep-exclusive headache that has been proposed. Hypnic headaches are brief, moderately severe, and affect the elderly primarily.

The purpose of this study was to identify long-term psychosocial effects of allogenic, syngenic and autologous haematopoetic stem cell transplantation (HSCT) on relevant parameters (physical performance, role and sexual functioning, intimate relationships, professional and social rehabilitation). A total of 163 patients, who had undergone an autologous (11.6%), syngenic (3.1%) or allogenic (85.3%) HSCT at the Department of Internal Medicine III, Ludwig-Maximilians-University, during a preceding 16-year period, were asked to complete the Herschbach Questionnaire on Stress in Cancer Patients in order to evaluate their current psychosocial distress status. An additional questionnaire for demographic data was used. Reduced quality of life as a result of HSCT is restored to its pre-HSCT level by most patients within 2 years after transplantation (no differences between groups transplanted 2-5, 6-9 or >10 years ago). The majority of patients had serious problems with "fitness" (24%), followed by problems with "pain" (17.2%) and "fear/emotional stress" (14.1%). Professional reintegration is an important factor in patients' well-being. However, 30.7% of these patients did not return to work at all. Unemployed patients had significantly higher scores for pain, anxiety, sleep disorders, depression, impairments in social functioning, partnership and family life. Only 9.8% of all patients took part in a psychotherapeutic programme and 39.3% in a rehabilitation programme. Identifying strategies for risk patients (e.g. lower education and married) need to be developed in order to optimize support for this group. Although some patients show a higher distress score in anxiety/fear and psychophysical performance, only 9.8% of all patients took advantage of available psychotherapy.

Consecutive patients with a minimum age of 65 years and at least one additional diagnosis participated in a standardized interview during the initial assessments in two geriatric hospitals ( n=86), a multidisciplinary pain center ( n=60), and three primary care practices ( n=117). The average age of the total sample was 76.29 years (SD=7.40); females constituted 73.3% of the sample. The average number of drugs consumed by the patients amounted to 7.31 (SD=2.66) with a maximum number of 19 drugs. Nearly three-quarters of the patients indicated a reduction in their pain by avoiding physical activity. Every second patient often felt depressed and without energy. The most frequent symptoms were a dry mouth, sleep disorders, fatigue, constipation, and dizziness. Patients from the geriatric hospitals were older and better educated, reported fewer painful body regions, indicated lower intensity and duration of pain as well as a lower number of pain medications. On the other hand, they were characterized by a higher intensity of comorbidity and by increased functional impairment. Patients from the pain clinic suffered more frequently from pain in the hip and the pelvis. They took stage I analgesics more often and admitted more frequently to adjusting the drug consumption to changes in well-being and situational factors. They felt the highest amount of impairment in their social activities. Nevertheless, they expressed the highest confidence in future improvement.

The aim of this work was to determine the concentration of total and ionized magnesium in hair and blood of patients with primary hypertension and the influence of oral magnesium supplementation (Slow-Mag B6) on clinical parameters and blood pressure values. 92 patients were recruited from the Family Care Unit, Pomeranian Academy of Medicine in Szczecin. Each patient was treated during at least 6 months preceding the study with a single antihypertensive agent from one of the following groups: ACE inhibitors, beta-receptor inhibitors, Ca channel blockers, diuretics. The control group included patients with hypertension not treated pharmacologically. Changes in ionized magnesium concentration before and after oral magnesium supplementation were studied in relation to total cholesterol, triglycerides, and other parameters of importance in hypertension. Significantly lower total magnesium concentrations were demonstrated in hair of patients receiving ACE inhibitors and diuretics in comparison to controls. Ionized magnesium concentrations in serum of hypertensive patients were significantly reduced as compared with controls. A highly significant increase in these levels was noted after magnesium supplementation. Blood pressure values after magnesium supplementation were reduced in the study group by an average of 15-20 mmHg for systolic and 5-9 mmHg for diastolic blood pressure. Correlations between ionized magnesium and triglyceride concentrations in patients treated with Ca channel blockers before oral Mg supplementation were found. Patients treated with diuretics demonstrated correlations between total magnesium and total cholesterol concentrations. Following oral magnesium supplementation with Slow-Mag B6 at 320 mg/day, the frequency of complaints reported by patients, including irregular heart beat, pricking heart pain, nervousness, sleep disorders, irritability/tearfulness was reduced. There was no effect on other complaints, such as mental and physical fatigue, constipation/diarrhea, and anxiety.
