Skeletal demineralisation and low serum concentrations of 25-hydroxy-vitamin-D were observed in patients with primary biliary cirrhosis. Neither oral nor parenteral vitamin-D increased 25-hydroxy-vitamin-D in serum or prevented further skeletal demineralisation. In contrast, oral 25-hydroxy-vitamin-D increased serum-25-hydroxy-vitamin D concentrations in(More)
Skeletal growth and mineralization in 54 adolescent and adult patients with inflammatory bowel disease have been analyzed comprehensively. Quantitative and qualitative radiologic techniques consisted of conventional roentgenography, photon absorptiometry, and radiographic morphometry. The data are correlated with the type, duration, and severity of disease,(More)
BACKGROUND Laparoscopic cholecystectomy, introduced less than 2 years ago, is widely accepted by patients and physicians despite the lack of controlled trials comparing this technology with conventional cholecystectomy. Recent series have described a variable incidence of biliary tract injury with laparoscopic gallbladder removal. The primary interaction of(More)
A 72-year-old female with ulcerative colitis of 30 years duration underwent total proctocolectomy for a cecal mass thought to be an adenocarcinoma. Pathologic examination of the colon revealed 22 tumors, all of which proved to be malignant lymphoma, histiocytic type. Thirteen cases of non-Hodgkins malignant lymphoma and 2 cases of Hodgkins disease of the(More)
Postprandial levels of copper, ceruloplasmin, iron, total iron binding capacity, cholesterol, vitamin A, carotene, folic acid, vitamin C, albumin, and total globulins in plasma, of 25-OH-vitamin D in serum, and of glutathione reductase activity, an index of riboflavin status, in erythrocytes were determined in a group of 18 juvenile cystic fibrosis patients(More)
Our nonphysician provider (NPP) experience has transformed the functioning and image of our practice. It allows the practice to care for poorly compensated or noncompensated patients and contains costs under managed care. NPPs enable our physicians to maintain reasonable workloads and focus their energy and skills on high-level diagnosis and treatment. This(More)
An unusual incidence of a duodenal leiomyosarcoma in a 10-year-old boy is presented. The corrected diagnosis was made after a 27-month course of occult gastrointestinal bleeding, vague abdominal complaints, and anemia. Gastrointestinal radiography and upper gastrointestinal endoscopy were useful in localizing the lesion. The tumor was removed at exploratory(More)
Acute dilatation of the colon with signs of systemic toxicity developed in an elderly man with malignant lymphoma. Although barium contrast X-rays taken previously were interpreted as consistent with granulomatous colitis, rectal biopsy had revealed features characteristic of malignant lymphoma, poorly differentiated lymphocytic type. Bone marrow and lymph(More)
