Sphenopalatine Ganglion Stimulation to Augment Cerebral Blood Flow: A Randomized, Sham-Controlled Trial.

Background and Purpose- Many patients with acute ischemic stroke are not eligible for thrombolysis or mechanical reperfusion therapies due to contraindications, inaccessible vascular occlusions, late presentation, or large infarct core. Sphenopalatine ganglion (SPG) stimulation to enhance collateral flow and stabilize the blood-brain barrier offers an alternative, potentially more widely deliverable, therapy. Methods- In a randomized, sham-controlled, double-masked trial at 41 centers in 7 countries, patients with anterior circulation ischemic stroke not treated with reperfusion therapies within 24 hours of onset were randomly allocated to active SPG stimulation or sham control.

Obesity is an independent predictor of mortality, especially among patients suffering from chronic illnesses. Basically, obesity occurs as a result of an imbalance between the amount of food consumed and the energy expenditure of a person. Obesity treatment is aimed at creating a new imbalance of reduced food intake and increased energy expenditure.

Attenuation of liver ischemia-reperfusion-induced atrial dysfunction by external pacing but not by isoproterenol.

Remote ischemia-reperfusion detrimentally affects myocardial function by initially interfering with the rate of contraction. We investigated the usefulness of isoproterenol versus external electrical pacing in attenuating secondary functional damage of isolated Wistar rat atria. Atrial strips (n = 10/group) were bathed within oxygenated Krebs-Henseleit solution that exited from isolated livers that had been either perfused normally (controls) or underwent no flow (ischemia) for 2 h.

Surgical treatment of lumbar spinal stenosis in patients aged 65 years and older.

Spinal stenosis syndrome affects mainly patients at their 5th-6th decades of life. The main goals of surgical treatment in the elderly are to allow the individual to walk longer distances, maintain the activities of daily living (ADL) and social life. Our aim was to evaluate the results of surgical treatment for lumbar spinal stenosis in elderly patients.

Does the combination of a simultaneous subcapital fracture of humerus and hip fracture in elderly patients carry a prognostic value?

The most important factor to cause hip fractures in elderly is probably osteoporosis. Other factors are the increase in fall frequency and the protective response to trauma. Osteoporotic fractures occur most commonly, at the hip, vertebra, distal radius and proximal humerus.

Deep skin slough following skin traction for hip fractures.

Introduction: Elderly patients who fracture their hips are susceptible to complications associated with bed rest before surgery. In some institutions a skin traction device is used in order to relieve pain before surgery. The authors followed ten patients who developed severe (deep) skin slough and evaluated the relationship to the skin traction device.
