Percutaneous disc decompression using Coblation (Nucleoplasty trade mark) implements the principle of volumetric reduction to achieve disc decompression and reduce intradiscal pressure. Previous analyses have shown that Nucleoplasty achieves reduction in volume and intradiscal pressure with minimal damage to surrounding tissue in the treated disc. ⋯ Nucleoplasty for disc decompression is one of the least-invasive techniques in the minimally invasive category, thus far exhibiting a very low incidence of complications. Although no long-term data are available, these preliminary results indicate that the Nucleoplasty procedure is a safe and moderately effective procedure for reducing pain in patients presenting with predominant discogenic low back pain associated with contained disc herniation.

We sought to identify predictors of death or discharge to home for patients with nontraumatic subdural hematoma (NT-SDH). ⋯ In this study, GCS score was the major predictor of outcome. Patients with NT-SDH who were male or with good GCS score were less likely to die and more likely to be discharged home. Unlike patients with intracerebral hemorrhage (ICH),lesion size did not predict outcome for patients with NT-SDH. Extent of involvement (on the right side) was a predictor of death.

Determining the appropriateness of selected surgical and medical management options in recurrent stroke prevention: a guideline for primary care physicians from the National Stroke Association work group on recurrent stroke prevention.
Despite a decade of successful clinical trials for stroke prevention, substantial gaps exist in the application and implementation of this information in community practice. The frequency of guideline use is low, and there remains controversy regarding the standard of practice. Patients with stroke may have multiple risk factors and concomitant stroke mechanisms, factors that are not addressed in stroke clinical trials and guideline statements. ⋯ Appropriateness was less where bleeding or surgical risk was excessive. Using consensus evidence from clinical trials, we have developed recurrent stroke prevention guidelines for routine and more complex patient scenarios according to appropriateness methodology. Broad application of these guidelines in primary practice promises to reduce the burden of recurrent stroke.

Children with sickle disease are at high risk for ischemic stroke and transient ischemic attacks, usually secondary to intracranial arteriopathy involving the terminal internal carotid and proximal middle cerebral and anterior cerebral arteries, which may be diagnosed using transcranial Doppler ultrasound or magnetic resonance angiography (MRA). Other central nervous system (CNS) complications include seizures and coma, which may be secondary to ischemic stroke, sinovenous thrombosis, reversible posterior leukoencephalopathy, or acute demyelination. The immediate priority after an acute CNS event is to improve cerebral oxygenation with oxygen supplementation to maintain peripheral saturation measured using pulse oximetry between 96% and 99%, and a simple transfusion of packed cells within an hour of presentation if the patient's hemoglobin is less than 10 g/dL. ⋯ Emerging primary prophylaxis regimens being tested include citrulline and arginine, aspirin, and overnight oxygen supplementation. Physicians caring for children with sickle cell disease also should ensure adequate nutrition, including five servings of fruit and vegetables a day. The role of vitamin supplementation is controversial, particularly when patients must take daily penicillin prophylaxis.

Myomectomy at time of cesarean delivery: a retrospective cohort study.
Myomectomy at time of cesarean delivery is traditionally discouraged because of the risk of hemorrhage. A retrospective cohort study was performed to determine whether myomectomy at time of cesarean delivery leads to an increased incidence of intrapartum and short-term postpartum complications. ⋯ In selected patients, myomectomy during cesarean delivery does not appear to result in an increased risk of intrapartum or short-term postpartum morbidity.
