The clinical, radiographic, and pathological findings in 155 patients with symptomatic Rathke's cleft cysts are discussed. Eight patients were treated by the authors and 147 were collected in a review of the literature. This lesion occurred more often in female than male patients by a 2:1 margin, and the mean age at presentation was 38 years. The average(More)
At every phase of its development, human-computer interaction has had its devices for disabling critical thinking. In recent years, terms like "hypertext" and "groupware" have sometimes functioned that way. But such excesses have been countered by critical and debunking literature (e.g., Jones, 1987; Grudin, 1991). I would like to draw attention to another(More)
The neurological complications secondary to embolism from atrial myxoma are reviewed. A patient with intracranial and skeletal metastases is described to emphasise the malignant potentiality of this tumour. A classification of atrial myxoma metastases is presented.
A case of a 29-year-old woman with a cystic lesion in the right cerebellopontine angle, who had three bouts of chemical meningitis in 1 year, is reported. The lesion proved to be a delicate, thin-walled cyst, in part with a squamous lining and in part with a respiratory epithelial (tall, columnar, ciliated, mucus-secreting) lining. Various possibilities to(More)
The technique of autologous iliac crest bone grafting is an important aspect in the treatment of patients with cleft lip, cleft palate, and other craniofacial disorders. In patients with cleft lip and palate, the alveolar bone graft creates a continuous maxillary arch, closes the oronasal fistula, provides bony support for facial soft tissue and teeth, and(More)
Retrospective study was done on 118 patients who underwent nonsurgical endodontics and then surgical endodontics. Seventy-nine patients had pain before nonsurgical endodontics, and an additional 39 were pain free. After the open surgical procedure, six patients (5%) had continual pain and were considered failures. Three patients (2.5%) were thought to have(More)
A double-blind, randomized study of 137 patients compared the effectiveness of single doses of etodolac, 200 and 400 mg, zomepirac, 100 mg, and placebo in relieving moderate to severe pain following third molar extractions. Throughout the 12-hour evaluation period, doses of both etodolac and zomepirac were significantly superior to placebo for total(More)
Spasticity may result in part from segmental spinal disinhibition. We determined the content and specific activity of glycine (the putative neurotransmitter thought to mediate spinal postsynaptic inhibition) and serine (the probable precursor of glycine) in feline spastic spinal cord following the intra-aortic administration of two labelled precursors of(More)
