Case Report History J. McA., a male aged 47 years, was first seen at a medical clinic of the Royal Southern Hospital on June i, 1954. He was complaining of attacks of unconsciousness for the past ten months. At first he had two or three fits a week, but they were now occurring as often as four or five times a day. The attacks were preceded by a buzzing in the left ear and were often followed by...

INTRODUCTION The carotid body tumour was first described by von Haller in 1743. The first two, unsuccessfully surgically treated carotid body tumours, were done by Reinger in 1880 (his patient died), and by Maydel in 1886 (his patient developed hemiplegia). Scudder made the first successful surgical removal of the carotid body tumour in 1903. Using data from the Cologne (Germany) Medline Resear...

The respiratory system is subject to the aging process, which could limit its responsiveness to hyperventilatory stimuli. Attenuation of the ventilatory response to hypoxia in old age is, as yet, an unresolved issue. Such attenuation may be germane for the pathogenesis of respiratory disorders developing more often in elderly subjects. The aim of this study was to determine the potential advers...

FIGuRE 1. Lateral tomogram of neck showing forward displacement of trachea by soft tissue mass (hollow arrows) with luminal narrowing (single solid arrow). extrinsic obstruction of the trachea is an extremely rare phenomenon. Elderr mentioned a rare patient with medias-tinal lymphoma may require immediate tracheostomy. Our patient did not present with peripheral bulky disease and her chronic ly...

The purpose of the present study was to investigate whether hypoxia influences acetylcholine (ACh) release from the rabbit carotid body and, if so, to determine the mechanism(s) associated with this response. ACh is expressed in the rabbit carotid body (5.6 +/- 1.3 pmol/carotid body) as evidenced by electrochemical analysis. Immunocytochemical analysis of the primary cultures of the carotid bod...
