Hemifacial spasm. Results of unilateral myectomy 总被引:1,自引:0,他引:1
Hemifacial spasm (HFS) is a disorder characterized by unilateral involuntary spasm of the muscles innervated by the facial nerve (cranial nerve VII). The etiology is often a redundant or ectatic artery in the cerebellopontine angle that compresses the facial nerve. Neurosurgical decompression with implantation of a sponge between the ectatic artery and the facial nerve produces good results, but has a high complication rate and a poor patient acceptance rate. Various modes of peripheral neurectomy have also been advocated, but the recurrence rate is high and the preexisting functional and cosmetic eyelid deformities are exacerbated. The results of unilateral periorbital myectomy in 21 HFS patients are presented. Follow-up ranging from 1 to 7 years was available on 16 patients. Excellent or good results were obtained in 94% of these cases, and postoperative complications were minor. Transient lymphedema and forehead anesthesia are the most common complications. An unforseen benefit of periorbital myectomy surgery is the improvement or relief of lower facial contractions that occurred in 75% of patients. The authors believe the myectomy procedure is a safe, effective, predictable therapy for those HFS patients unwilling to risk a neurosurgical operation, and allows simultaneous reconstruction of associated eyelid and eyebrow deformities. 相似文献

Few things in life are as disconcerting to a woman as losing her hair. Yet thinning hair, usually from age or a genetic predisposition to male-pattern balding, is a common problem. In this article, Dr Parkinson discusses causes of thinning hair, how to differentiate them, and how to treat them. 相似文献

Veterans experience chronic pain at greater rates than the rest of society and are more likely to receive long-term opioid therapy (LTOT), which, at high doses, is theorized to induce maladaptive neuroplastic changes that attenuate self-regulatory capacity and exacerbate opioid dose escalation. Mindfulness meditation has been shown to modulate frontal midline theta (FMT) and alpha oscillations that are linked with marked alterations in self-referential processing. These adaptive neural oscillatory changes may promote reduced opioid use and remediate the neural dysfunction occasioned by LTOT. In this study, we used electroencephalography (EEG) to assess the effects of a mindfulness-based, cognitive training intervention for opioid misuse, Mindfulness-Oriented Recovery Enhancement (MORE), on alpha and theta power and FMT coherence during meditation. We then examined whether these neural effects were associated with reduced opioid dosing and changes in self-referential processing. Before and after 8 weeks of MORE or a supportive psychotherapy control, veterans receiving LTOT (N = 62) practiced mindfulness meditation while EEG was recorded. Participants treated with MORE demonstrated significantly increased alpha and theta power (with larger theta power effect sizes) as well as increased FMT coherence relative to those in the control condition—neural changes that were associated with altered self-referential processing. Crucially, MORE significantly reduced opioid dose over time, and this dose reduction was partially statistically mediated by changes in frontal theta power. Study results suggest that mindfulness meditation practice may produce endogenous theta stimulation in the prefrontal cortex, thereby enhancing inhibitory control over opioid dose escalation behaviors.Subject terms: Human behaviour, Addiction 相似文献

The epidemiology of hyperuricaemia and gout in Taiwan aborigines 总被引:4,自引:1,他引:4
To determine the prevalence of hyperuricaemia, gout and gout-related
factors in Central Taiwan Atayal aborigines, 342 subjects over 18 yr old
were interviewed and examined. A questionnaire was designed to screen for
signs and symptoms of gout and gout-related risk factors. Serum uric acid,
triglyceride and creatinine were measured in all subjects. The prevalence
of hyperuricaemia was 41.4% and that of gout 11.7% in aborigines. The uric
acid level was 7.9+/-1.7 mg/dl in males and 5.7+/-1.5 in females, and
differed significantly under age 70 yr (P < 0.001). Significantly
increased triglyceride, creatinine and alcoholism was found in gouty
patients compared with non-gouty patients. In 40 cases with gout, 54% had
tophi and 35% of their first- degree relatives had gout. The high
prevalence of hyperuricaemia and gout in Taiwan Atayal aborigines, a
significant family predisposition, increased creatinine level and
alcoholism suggest multiple factors affecting the hyperuricaemia.
