To determine the rate of subacute recanalization and reocclusion and its effect on clinical outcomes among patients with ischemic stroke treated with endovascular treatment. Subacute recanalization and reocclusion occurring hours after completion of the intravenous or intra-arterial thrombolysis for acute ischemic stroke has been reported in anecdotal cases. ⋯ We found that new or additional recanalization occurs in one-fourth of the patients within 24 h of endovascular treatment and is not associated with any adverse consequences. Subacute reocclusion occurs infrequently after endovascular treatment.

Case Reports
Cerebral air embolism resulting in fatal stroke in an airplane passenger with a pulmonary bronchogenic cyst.
Cerebral air embolism is a rare cause of stroke, but may occur in patients undergoing invasive cardiac and pulmonary procedures, as well as in divers suffering pulmonary barotrauma from rapid ascent. Cerebral air embolism during air travel, however, is particularly rare. ⋯ This case suggests the importance of considering cerebral air embolism in patients with stroke associated with air travel; restricting air travel in patients with intrapulmonary cysts may be prudent.

The initial noncontrast computed tomography (CT) study of the head after an aneurysmal subarachnoid hemorrhage (SAH) is used to predict the risk of developing vasospasm. Changes in the extent of subarachnoid blood seen on CT images occur as a function of time after SAH, but there is no consensus on the time interval during which this study needs to be completed. ⋯ We propose that only CT scans obtained within 24 h of a subarachnoid bleeding event should be used to estimate the risk of vasospasm.

Stroke is the third most common cause of death in the Western World and is a condition seen by Neurologists, General Physicians and Primary Care Physicians. Neurogenic pulmonary edema can complicate the management of large strokes and cerebral hemorrhage. While the principles of management of this type of pulmonary edema are similar to the more common cardiogenic pulmonary edema, placing a patient in the prone position may be a helpful maneuver facilitating recovery. ⋯ This technique of prone positioning for ventilation is of importance to physicians who manage stroke and its complications.

The role of non-invasive ventilation and factors predicting extubation outcome in myasthenic crisis.
Myasthenic crisis is a great threat to patients with myasthenia gravis. Usage of non-invasive ventilation (NIV) to prevent intubation and timing of extubating of patients in myasthenic crisis are important issues though not well documented. ⋯ NIV may be applied to those patients with a low APACHE II score and a lesser degree of metabolic compensation for respiratory acidosis. For patients undergoing invasive mechanical ventilation, extubation failure is associated with significant in-hospital morbidity in myasthenic crisis. Adequate levels of Pemax and cough strength correlate significantly with extubation success.
