Giant aneurysm of the petrous carotid artery presenting with facial numbness.

We present the case of a 56-year-old man who complained of numbness in his cheek, and was shown to have a very large partly thrombosed aneurysm of the ipsilateral petrous carotid artery. The radiological findings and differential diagnosis are discussed. Aneurysm of the petrous carotid should be included in the differential diagnosis of any parasellar mass.

An automatic sigh feature for animal ventilators.

A device is described that provides a reliable automatic deep breath to an animal being ventilated with a typical laboratory ventilator. The deep breath is provided by closing a solenoid valve in the expiratory tubing causing the animal to inspire two, three, or four consecutive tidal volumes without expiration. The interval between deep breaths is selected to be every 1, 2, 4, 6, 8, or 10 min. Control of this interval is provided by simple integrated circuits. Total parts cost of this device is approximately $90.
