Ninety patients who had suspected or confirmed fenestral or cochlear otosclerosis underwent CT examination. Foci of demineralization in the otic capsule were discovered in 20 ears (12 patients). Audiometric studies of the 12 patients revealed sensorineural hearing loss (SNHL) with distinct correlation of CT findings with progressivity and with involvement(More)
Enhanced expression of heat shock protein (HSP) has been shown to be protective against laboratory models of septic shock. Induction of HSPs to improve outcome in human disease has not been exploited because laboratory induction agents are themselves toxic and not clinically relevant. In this study, we demonstrate that a single dose of intravenous glutamine(More)
We have recently examined three young patients with congenital unilateral profound sensorineural hearing loss. On computed tomography the only abnormality discovered was a remarkably enlarged vestibular aqueduct on the abnormal side. The vestibular aqueduct syndrome is an important cause of congenital hearing loss. Although this finding has been well(More)
Of more than 200 patients who underwent high-resolution computed tomography (CT) of the middle ear, the vast majority had tubotympanic disease in one of its forms: middle ear effusion, tympanosclerosis, granulation tissue, tympanic membrane retractions, or acquired cholesteatoma. The CT appearance of each of these conditions is discussed and illustrated.(More)
Thirty-five consecutive patients with the clinical diagnosis of fenestral otosclerosis were evaluated with high-resolution computed tomography (CT). Twenty-six were diagnosed as having this disorder by CT evidence of abnormal bony excrescences at or adjacent to the oval window. The diagnosis was made upon examination of 1.5-mm-thick targeted sections(More)
OBJECTIVE To determine the effect of intravenous glutamine supplementation vs. an isonitrogenous control on infectious morbidity in severely burned patients. Previous clinical studies in seriously ill patients suggest a beneficial effect of glutamine on infectious morbidity, but no trials have examined possible clinical benefits in severely burned patients.(More)
High-resolution computed tomography (CT) provides an excellent method for examination of the surgically altered middle ear and mastoid. Closed-cavity and open-cavity types of mastoidectomy are illustrated. Recurrent cholesteatoma in the mastoid bowl is easily diagnosed. Different types of tympanoplasty are discussed and illustrated, as are tympanostomy(More)
Clinical trials have demonstrated that glutamine (GLN) supplementation can decrease infectious morbidity and improve survival in a number of settings of critical illness. The mechanism of this protection remains unclear. The objective of this study was to evaluate the effect of GLN on cytokine release, organ injury, and survival from endotoxin-induced(More)
