Multidisciplinary evaluation in erectile dysfunction after radical prostatectomy.

Radical prostatectomy is associated with a postoperative impotence rate of 90%, a sequel that is the least acceptable to the patient. The use of the nerve-sparing procedure according to Walsh (1) with 70% restoration of sexual power postoperatively is limited considering the prevalence of periprostatic tumour invasion. A method is described which satisfies the demand for both a radical surgical procedure and postoperative restoration of sexual power.

Familial polyposis coli in childhood.

Familial polyposis coli has generally been considered a disorder of adulthood that is rarely identified in children. We report 3 affected kindreds in which the disorder was diagnosed in 6 of 11 potentially affected children between 8 and 16 years of age. Experience with these kindreds demonstrates that polyps frequently develop during childhood in affected individuals. Colonoscopy was found to be preferable to the air-contrast barium enema, in that it was as sensitive a technique for detection of adenomas, and in that it also permitted collection of biopsies for histologic confirmation. We recommend that colonoscopy be performed late in the first decade of life before symptoms develop. Total colectomy, rectal mucosectomy, and ileo-anal anastomosis eliminated the risk of malignancy, preserved anal sphincter function by both clinical and manometric assessment, and was readily adapted to by these children.

Nutritional rehabilitation of malnourished patients with cystic fibrosis.

We examined the effect of nutritional rehabilitation in cystic fibrosis patients with severe disease. Thirteen malnourished patients (seven males, six females, age 7-27 yr) were studied over 7-16 mo. Oral supplementation was attempted initially in 12 patients (mean duration 6.7 mo); only 2 patients gained weight, 2 withdrew, and 1 died. The remaining 7 patients failed to achieve adequate weight gain and were commenced on nasogastric supplementation with a semisynthetic formula. An additional patient was entered without a prior period of oral supplementation because of the severity of malnutrition. Weight gain was achieved in 7 of 8 patients with nasogastric supplementation (mean duration 6.4 mo). Weight gain was associated with an increase in lean body mass, total body fat, and height velocity. While pulmonary function and biochemical parameters were unchanged, patient well-being improved and episodes of pneumonia decreased.

Granulopoiesis in Shwachman's syndrome (pancreatic insufficiency and bone marrow dysfunction).

Granulopoiesis was studied in 10 children with Shwachman's syndrome (chronic neutropenia and exocrine pancreatic insufficiency). Marrow proliferative activity assessed by determination of mitotic indices and tritiated thymidine uptake into granulocytic cells was normal. Assay of bone marrow granulocyte colony-forming cells (CFU-C) in a methylcellulose tissue culture system demonstrated normal CFU-C numbers in four patients and reduced numbers in five. The granulocyte colonies formed were indistinguishable from normal colonies morphologically. Production of colony-stimulating activity (CSA) from patients' peripheral blood leukocytes appeared normal when tested on control marrow. No serum inhibitors against CFU-C or CSA could be demonstrated using both control and autologous marrow, and co-culture of patients' peripheral blood lymphocytes with control marrow did not inhibit CFU-C growth. We conclude that in Shwachman's syndrome committed granulocytic stem cells are present, and the numbers detected in vitro vary widely as does the clinical neutropenia. The proliferative activity of recognizable granulocytic cells is normal and neither a deficiency of humoral stimulators nor the presence of serum or cellular inhibitors of granulopoiesis can be demonstrated.
