[Hearing results of cholesteatoma middle ear surgery using open and closed techniques].

The author described an analysis of hearing results in open and closed tympanoplasties of ear cholesteatoma. 172 patients were operated upon. 73 have had open and 99 closed technique. The better hearing results were obtained in closed surgery, but not so good as expected. The unsuccessful hearing results were two times frequent in open surgery. We prefer the two step closed intervention after all pathologic lesions being eradicated.

Serum retinol level in patients with colorectal premalignant and malignant lesions.

Serum retinol levels were determined by a fluorometric method in patients with colorectal cancer or polyps and those with inflammatory bowel disease. Serum retinol levels in patients with benign or malignant colorectal polyps and stage B cancer (modified Dukes' classification) were similar to those found in controls. By contrast, serum retinol levels were significantly lower in patients with Dukes' stage C or D. Among cancer patients that were followed after surgical treatment serum retinol levels did not differ significantly from those found in controls. Patients who died of metastases during follow-up possessed very low serum retinol levels. These findings suggest that a decreased serum retinol level in cancer patients is a consequence rather than a precursor of the neoplastic process. Furthermore, this study suggests that the marked decrease in serum retinol level might be an indicator of poor prognosis in colorectal cancer patients after surgery.

Short- and long-term results of colonoscopic polypectomy in children.

Eighty-four colorectal polyps of up to 3.3 cm in diameter were removed with the diathermy snare during 48 colonoscopies on 42 children, aged 2 to 18 years (mean, 7.4 years). Most polyps were juvenile and the majority were located in the sigmoid colon (55%) or rectum (37%). No complications related to medication, colonoscopy, or snare polypectomy were observed. The two presenting symptoms, rectal bleeding and anemia, disappeared soon after polypectomy in all but one patient with adenomatous polyposis coli, subsequently operated upon. Follow-up examinations, including total colonoscopy, performed 4 months to 7 years (mean, 25 months) later did not reveal abnormalities in any of the 37 children whose previously removed polyps were juvenile. The authors conclude that endoscopic snare polypectomy is an effective and safe treatment for colorectal polyps in the pediatric age group.
