Use of sleep-promoting medications in nursing home residents : risks versus benefits. This paper reviews the use of sleep-promoting medications in nursing home residents with reference to risks versus benefits. Up to two-thirds of elderly people living in institutions experience sleep disturbance. The aetiology of sleep disturbance includes poor sleep hygiene, medical and psychiatric disorders, sleep apnoea, periodic limb movements and restless leg syndrome. One key factor in the development (...) to avoid long-acting benzodiazepines and to use hypnotics for as brief a period as possible, in most cases not exceeding 2-3 weeks of treatment. Patients receiving benzodiazepines are at increased risk of daytime sedation, falls, and cognitive and psychomotor impairment. Zaleplon, zolpidem, zopiclone and eszopiclone may have some advantages over the benzodiazepines, particularly with respect to the development of tolerance and dependence.

Moreover, transdermal dopaminergic drugs, particularly rotigotine, seem the ideal treatment for patients experiencing restless legs syndrome or periodic limb movement disorder during sleep, disorders that are quite common in elderly people or in association with neurodegenerative diseases. Unlike dopaminergic drugs (...) administration of drugs during the day to maintain constant plasma medication levels, which in turn increases the likelihood of poor adherence. Consequently, several attempts have been made to develop pharmacological preparations that can achieve a constant rate of drug delivery. For example, transdermal lisuride and apomorphine have been shown to reduce motor fluctuations and duration of 'off' periods in advanced Parkinson's disease, while rotigotine allows significant down-titration of levodopa without

), was established for in vivo imaging of arteriogenesis in mice and compared with LDPI.Using the accepted model of ligation of the left femoral artery of 45 C57BL6 mice, we determined arteriogenesis both by LDPI and ICGA, which were applied before and periodically after ligation of the left femoral artery (each group n = 7). Collateral artery growth within the hind limb was additionally verified by histologic workup.Determination of flow by ICGA, as represented by maximal pixel intensity (ratio of left/right (...) increase in the number of collaterals. The intraindividual ratio increased from 1.0 +/- 0.05 before ligation to 1.35 +/- 0.10 at 2 weeks and 1.41 +/- 0.08 at 3 weeks after ligation (P < .05).Our data demonstrate that ICGA represents a potent tool for the quantification of collateral flow in small animal models. The current standard of LDPI seems to rather represent blood movements within the superficial skin but not of the entire hind limb.

Longitudinal centerline stent graft movement at 1 year was similar in the suprarenal and infrarenal groups (4.3 +/- 4.4 mm vs 4.8 +/- 4.3 mm; P = .6). Patients with longitudinal centerline movement of more than 5 mm at 1 year or clinical evidence of migration at any time during the follow-up period comprised (...) graft was measured on preoperative, postimplantation, and 1-year three-dimensional computed tomographic scans, with movement more than 5 mm considered to be significant. Aortic diameters were measured perpendicular to the centerline axis. Proximal and distal fixation lengths were defined as the lengths of stent-graft apposition to the aortic neck and the common iliac arteries, respectively.There were no significant differences in age, comorbidities, or preoperative aneurysm size (suprarenal, 6.0 cm

and outcomes were similar in both types of wounds. There was 1 death in the study group, and 1 patient required skin grafting. All other survivors had healing by secondary intention without disability. The period for complete epithelization varied between 3 and 8 weeks. Patients were discharged home when 70% of the wound had healed. There was extensive scarring in 3 children with NF involving the back. The other children had minimal or no scarring. None of the patients had any restriction in the movement (...) of limbs or joints. These findings were compared with 16 retrospective patients of NF treated before January 2000 by the conventional approach of aggressive early debridement, the results of the conservative approach were superior with shorter hospital stay, lower number of blood transfusions, earlier appearance of granulation tissue, and shorter duration of complete healing.We conclude that the conservative management of NF offers advantages in morbidity without compromising the outcome.

limb movement disorder, circadian rhythm disorder, insomnia, and hypersomnia. Headache, particularly morning headache and chronic headache, may be consequent to, or aggravated by, a sleep disorder, and management of the sleep disorder may improve or resolve the headache. Sleep-disordered breathing is the best example of this relationship. Insomnia is the sleep disorder most often cited by clinical headache populations. Depression and anxiety are comorbid with both headache and sleep disorders (...) Headache and sleep disorders: review and clinical implications for headache management. Review of epidemiological and clinical studies suggests that sleep disorders are disproportionately observed in specific headache diagnoses (eg, migraine, tension-type, cluster) and other nonspecific headache patterns (ie, chronic daily headache, "awakening" or morning headache). Interestingly, the sleep disorders associated with headache are of varied types, including obstructive sleep apnea (OSA), periodic

. In a second period monitoring 177 patients, lumbar catheter insertion was abandoned in favour of exclusive thoracic placement for epidural catheters. Additionally, to prevent outward movement, the catheters were inserted deeper into the epidural space (mean (SD) 5.2 (1.5) cm in Period Two vs 4.6 (1.3) cm in Period One). Lower leg motor weakness declined from 14.7% to 5.1% (odds ratio 0.35; 95% confidence interval 0.16-0.74) between the two periods. Similarly, the frequency of premature catheter (...) Audit of motor weakness and premature catheter dislodgement after epidural analgesia in major abdominal surgery. In a quality improvement audit on epidural analgesia in 300 patients after major abdominal surgery, we identified postoperative lower leg weakness and premature catheter dislodgement as the most frequent causes of premature discontinuation of postoperative epidural infusion. Lower limb motor weakness occurred in more than half of the patients with lumbar epidural analgesia

with either a locked unreamed tibial nail or a monolateral fixator in a sheep model. Interfragmentary movements and ground reaction parameters were monitored in vivo throughout the healing period. After sacrifice, the tibiae were examined mechanically and histologically. Bending angles and axial torsion at the fracture site were larger in the nail group within the first five weeks post-operatively. Unlike the fixator group, the operated limb in the nail group did not return to full weight bearing during (...) the treatment period. Mechanical and histomorphometrical observations showed significantly inferior bone healing in the nail group compared to the fixator group. In this study, unreamed nailing of a tibial diastasis did not provide rotational stability of the osteosynthesis and resulted in a significant delay in bone healing.

3015. The two faces of Eve: dopamine's modulation of wakefulness and sleep. (Abstract)

The two faces of Eve: dopamine's modulation of wakefulness and sleep. In Parkinson's disease (PD), waking is frequently punctuated by sleep episodes, including rapid eye movement (REM) (i.e., dream) sleep, and sleep is interrupted by motor activities such as periodic limb movements and REM sleep behavior disorder. Because these pathologic behaviors are unaccounted for by contemporary models, this review summarizes the complex effects of dopamine (DA) on normal and pathological waking-sleeping (...) . Maintenance of wakefulness is probably promoted by mesocorticolimbic DA circuits, and suppression of nocturnal movement appears to be influenced by indirect pathways linking midbrain DA neurons with pre-motor structures in the mesopontine tegmentum and ventromedial medulla. A diencephalospinal DA system may have an additional important role in mediating state-specific sensorimotor activity that is relevant to periodic limb movements and restless legs syndrome.

is a syndrome characterised by a severely increased dopamine concentration in the CNS; overstimulation of the dopamine D1 receptors compared with D2 receptors in the spinal cord may lead to D1-related pain and generate periodic limb movements; iron deficiency may be a main predisposing factor of augmentation, probably caused by a reduced function of the dopamine transporter; therapy with levodopa or dopamine agonists should remain at low doses and; iron supplementation and opiates are the therapy of choice

beverages per week) reduced the risk for sleepiness. Multiple risk factors were more commonly present in those with complaints of sleepiness. The presence of periodic limb movements, which are common in older adults, was not associated with sleepiness.There is a distinct differential diagnosis of excessive daytime sleepiness in older adults. Many of the risk factors that we identified are treatable.Ann Neurol 2006;59:893-904. (...) . Multivariable modeling identified the following as simultaneously significant risk factors for excessive sleepiness: severe sleep-disordered breathing (apnea-hypopnea index, >30 episodes/hr), self-report of poor sleep quality, increased percentage of time in rapid eye movement sleep, pain at night at least three times per week, wheezing or whistling from chest at night, and medications with sleepiness as a side effect. Male sex also was associated with increased risk, whereas alcohol use (more than seven

Left hemibody myoclonus due to anomalous right vertebral artery. A 43-year-old man presented with sporadic, sudden, brief, and involuntary jerks of his left limbs and trunk muscles. The electromyographic recordings showed short-lasting highly synchronized bursts, compatible with myoclonus limited to the left hemibody. Blink reflex, masseter silent period, cortical and spinal magnetic stimulation, somatosensory cortical evoked potentials, and electroencephalogram (EEG) were normal; the EEG back (...) -averaging showed no spikes preceding the myoclonus. Magnetic resonance imaging and magnetic resonance angiography showed the presence of an anomalous nonectasic right vertebral artery compressing the right side of ventral medulla oblongata. We hypothesize that the aberrant right vertebral artery induced abnormal activation of descending motor tracts responsible for the myoclonus.(c) 2004 Movement Disorder Society.
