Facioscapulohumeral muscular dystrophy (FSHD) is one of the most frequent forms of muscular dystrophy. The aims of this study were: 1) to evaluate the prevalence of sleep disordered breathing (SDB) in patients with FSHD; 2) to define the sleep-related respiratory patterns in FSHD patients with SDB; and 3) to find the clinical predictors of SDB. Fifty-one consecutive FSHD patients were enrolled, 23 women, mean age 45.7+/-12.3 years (range: 26-72). ⋯ The presence of SDB does not depend on the clinical severity of the disease. SDB is often asymptomatic, and no clinical or physical measure can reliably predict its occurrence. A screening of SDB should be included in the clinical assessment of FSHD.

Cerebrovascular reactivity (CVR) testing with CO2 challenge is used clinically as a measure of cerebrovascular reserve. However it is not known whether CVR measures the same physiological process as spontaneous cerebral autoregulation (CA). ⋯ We showed a decrease in spontaneous CA after vasodilatation. However, the lack of correlation between baseline CA and degree of CVR suggests that cerebrovascular reserve and CA are based in part on distinct physiological mechanisms. Further studies are needed to determine which of these parameters is most useful to guide treatment decisions in pathological states.

The purpose of the study is to investigate the embolic potential as well as ultrasonic characteristics of plaques in patients presenting with severe unilateral restenosis at least 1 year after carotid endarterectomy (CEA), compared with patients with severe unilateral primary carotid stenosis. ⋯ Carotid plaques in patients with severe unilateral carotid restenosis at least 1 year after surgery and in patients with primary lesions are similar in their embolic potential and ultrasonic characteristics.

Randomized Controlled Trial
Efficacy and tolerability of pregabalin in essential tremor: a randomized, double-blind, placebo-controlled, crossover trial.
We performed a double-blind, crossover-design study to assess the tolerability and efficacy of pregabalin (PGB) in patients with essential tremor (ET). Twenty patients (11 women; mean age of 62.2+/-12.7 years, mean ET duration of 25.5+/-14.9 years) with ET were randomized for treatment with PGB (150-600 mg/day) or placebo, titrated over 6 weeks. ⋯ We found no improvement in any of the TRS measures and a statistically significant worsening of QUEST scores while patients were taking PGB. Adverse events were similar in frequency to previously published studies of PGB, the most common being drowsiness and dizziness.

Case Reports
Spontaneous spinal epidural hematoma: an urgent complication of adding clopidogrel to aspirin therapy.
We report a 56-year-old patient who had been taking antihypertensive medication in combination with prophylactic aspirin for 19 years who was diagnosed with stable angina with significant coronary artery stenosis on angiography. He was treated with drug-eluting coronary stent placement. Clopidogrel was added to the previous treatment regimen after stent placement. ⋯ The present case is interesting because it is the first case in spine which corresponds to the findings of MATCH study that bleeding tendency would be raised by dual antiplatelet treatment (aspirin+clopidogrel). With the popularity of antiplatelet medications, physicians should be aware of this critical side effect and provide urgent treatment. Furthermore, we should be cautious when we prescribe clopidogrel in addition to aspirin because it could cause bleeding complications like SSEH.
