Self-reported sleep disturbances and levels of vitality and fatigue were studied in a secondary analysis of 25 pregnant and 29 postpartum employed women. Results indicate that pregnant women have problems initiating and maintaining sleep, and postpartum women have problems maintaining sleep, but not falling asleep. The primary reason for midsleep awakenings was urinary frequency among the pregnant women, and child care responsibilities among the postpartum women. Chronic sleep disturbance was indicated by a greater percentage of postpartum women who fell asleep easily, very few who felt highly energetic at work, and most who perceived a high level of fatigue during the past week. Even with these sleep disruptions, no differences occurred in the mean scores for perception of fatigue and vitality between the two groups. Clinicians can use these findings to educate women about some changes they may anticipate and how they might manage them during pregnancy and postpartum.

Respiratory and sleep disturbances may be important causes of morbidity in Steele-Richardson-Olszewski syndrome but the frequency and character of nocturnal abnormalities remains uncertain. A prospective study of 11 patients with Steele-Richardson-Olszewski syndrome and age-matched control subjects was undertaken using clinical assessments, a structured sleep questionnaire, spirometry, static maximum inspiratory and expiratory pressures and nocturnal oximetry. The mean age of the Steele-Richardson-Olszewski syndrome patients was 63.2 (52-70) years and mean disease duration was 4.0 (2-6) years. There was moderate to severe motor disability in nine and mild to moderate dementia in eight. In the patients with Steele-Richardson-Olszewski syndrome the following abnormalities contributed to sleep disturbances significantly more frequently than in normal controls: depression, dysphagia, frequent nocturnal awakenings (usually associated with urinary frequency), immobility in bed, difficulty with transfers, impaired dressing and feeding. There was profound impairment of voluntary respiratory control whilst automatic and limbic control were well maintained. Nocturnal respiratory abnormalities were not present even in the most severely disabled. In Steele-Richardson-Olszewski syndrome sleep abnormalities are common; they relate to the cognitive, pseudobulbar and extrapyramidal disturbances and may therefore be amenable to symptomatic control.

The relationship between nocturnal urinary frequency and sleep disturbances is investigated in aged men in 12 rural towns in Kyoto and Shiga Prefectures. The subjects were 178 men who did not have diseases or symptoms that were likely to affect urinary condition or sleep. There were no significant differences in sleep disturbances, except sleep maintenance, between the normal group (nocturnal urinary frequency below twice per night) and the abnormal group (nocturnal urinary frequency twice or more per night). In healthy aged men, nocturnal urinary frequency only caused disturbance in sleep maintenance, but did not cause any other sleep disturbance.

Overactive bladder (OAB) is a common condition characterised by the symptoms of urinary frequency and urgency, with or without urge incontinence and nocturia. The prevalence of OAB increases markedly with age in both men and women. OAB can have a detrimental effect on physical functioning and psychological well-being, as well as significantly reducing quality of life. Antimuscarinic therapy -- with or without behavioural therapy -- represents the most common treatment for patients with OAB. Several antimuscarinic agents are currently available for the treatment of OAB in adults, including oxybutynin, tolterodine, trospium chloride, darifenacin and solifenacin. The antimuscarinics all appear to exert their clinical effect through inhibition of the bladder muscarinic receptors, but they vary both in structure and in their functional profile. While efficacy has been demonstrated in adult populations (including patients >65 years of age), few studies have been reported specifically in a geriatric population, and antimuscarinics are often underutilised in the elderly despite the marked increase in the prevalence of OAB in this age group. One explanation for this apparent underuse of an effective treatment option may be concerns about the frequency of anticholinergic adverse events, such as dry mouth; the likelihood of detrimental CNS effects, including cognitive impairment and sleep disturbances; and the potential for harmful interactions with existing pharmacotherapy. When selecting an antimuscarinic agent for the management of an elderly patient presenting with OAB, in addition to considering evidence of clinical efficacy and tolerability, issues of safety specific to an older population should be borne in mind. In particular, the likelihood of detrimental CNS effects should be considered, including cognitive impairment and sleep disturbances, secondary to anticholinergic load. Oxybutynin and tolterodine have both been associated with cognitive adverse events and effects on sleep architecture and quality. In contrast, trospium chloride and darifenacin do not appear to be associated with cognitive adverse events and trospium chloride does not negatively affect sleep architecture or quality. Biotransformation by the cytochrome P450 (CYP450) system is an important step in the activation or elimination of a large number of drugs, including oxybutynin, tolterodine, darifenacin and solifenacin, raising the possibility of clinically relevant and potentially serious drug interactions. In elderly patients, such interactions are of particular relevance given the potential for declining activity of certain members of the CYP450 family combined with decreased hepatic blood flow, which can reduce first-pass metabolism and thus the bioavailability of drugs metabolised via this route. Of the antimuscarinic agents used to treat OAB, only trospium chloride is not extensively metabolised in the liver by the CYP450 system and is excreted largely as the active parent compound in the urine. This paper provides an overview of the pathophysiology of OAB and reviews current approaches to achieving a differential diagnosis and selecting appropriate treatment for the older patient. The pharmacology and clinical effects of current medication for the treatment of OAB symptoms in patients defined by the OAB pharmacology literature as 'elderly' are also reviewed.

Fibromyalgia (FM) is a generalized chronic pain condition that is often accompanied by symptoms such as fatigue, sleep disturbances, psychological and cognitive alterations, headache, migraine, variable bowel habits, diffuse abdominal pain, and urinary frequency. Its key assessment domains include pain, fatigue, disturbed sleep, physical and emotional functioning, and patient global satisfaction and health-related quality of life (HRQL). A number of evaluation measures have been adapted from the fields of rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis, and others such as the Fibromyalgia Assessment Status (FAS) index and the Fibromyalgia Impact Questionnaire (FIQ) have been specifically developed. The aim of this study was to assess the impact of FM on HRQL by comparing the performance of the FAS index, the FIQ and the Health Assessment Questionnaire [HAQ] in 541 female and 31 male FM patients (mean age 50 years; mean disease duration 7.7 years) entered in the database of a web-based survey registry developed by the Italian Fibromyalgia Network (IFINET). Tests of convergent validity showed that the FAS index and FIQ significantly correlated with each other (rho=0.608, p<0.0001), but there were also significant correlations between the FAS index and other clinical measures of disability, including the HAQ (rho=0.423, p<0.0001), anxiety (rho=0.138, p=0.0009), depression (rho=0.174, p<0.0001) and, especially, the number of comorbidities (rho=0.147, p=0.0004). The FAS index revealed a statistically significant difference between males and females (p=0.048), analysed using the Mann-Whitney U-test for all pair wise comparisons. The FAS index is a valid three-item instrument (pain, fatigue and sleep disturbances) that performs at least as well as the FIQ in FM patients, and is simpler to administer and score. Both questionnaires may be useful when screening FM patients, with the choice of the most appropriate instrument depending on the setting.
