PURPOSE: Patients with familial adenomatous polyposis need prophylactic colectomy and ileorectal anastomosis or restorative proctocolectomy. Preoperative rectal polyp counts have been used as one factor to determine which operation should be done, triaging patients according to risk of rectal cancer or completion proctectomy after ileorectal anastomosis. This study was designed ...

The elderly have an increased incidence of oropharyngeal colonization with respiratory pathogens, a well-known risk factor for the development of pneumonia. Changes in the oral milieu may occur secondary to decreased salivary production and abnormalities in swallowing. These abnormalities, common in the elderly, may result in impaired clearance of organisms, ...

Tracheoesophageal voice prostheses in laryngectomized patients commonly deteriorate due to the presence of yeasts, particularly Candida species. We describe the first case of colonization of such a device by Cryptococcus neoformans in a patient with a history of glottic carcinoma. The isolate showed an identical genomic pattern with C. neoformans ...

PURPOSE: After resection of the distal rectum with a straight reanastomosis, poor bowel function can occur. This is felt to be because of the loss of the rectal reservoir. To overcome this, a neoreservoir using a colonic J-pouch has been advocated in low colorectal and coloanal anastomosis. However, difficulties in ...

Bulmer M - - 2000
BACKGROUND: Rigid sigmoidoscopy forms an integral part of the out-patient assessment of patients with colorectal symptoms. However, the value of this of this examination is often diminished by faecal loading of the rectum. This trial aimed to determine the ability of a single self-administered glycerine suppository to clear the rectum ...
Trevisani G T - - 2000
BACKGROUND: Ogilvie's syndrome, or acute colonic pseudo-obstruction, is a common and relatively dangerous condition. If left untreated, it may cause ischemic necrosis and colonic perforation, with a mortality rate as high as 50 percent. Neostigmine enhances excitatory parasympathetic activity by competing with acetylcholine for attachment to acetylcholinesterase at sites of ...
