Abstract: Gastrointestinal motor function in patients with primary anorexia nervosa has rarely been investigated. We studied oesophageal motor activity in 30 consecutive patients meeting standard diagnostic criteria for primary anorexia nervosa (Feighner et al; DSM III). Seven were found to suffer from achalasia instead of primary anorexia nervosa, one from diffuse oesophageal spasm and one from severe gastro-oesophageal reflux and upper oesophageal sphincter hypertonicity, while partly non-propulsive and repetitive high amplitude, long duration contractions prevailed in the lower oesophagus of another six. In four patients with oesophageal dysmotility not responding to therapy and in 12 of 15 patients with normal oesophageal manometry, gastric emptying of a semisolid meal was studied. Emptying was normal in only three but markedly delayed in 13 cases (half emptying times 97-330 min, median: 147 min, as compared with 21-119 min, median: 47 min, in 24 healthy controls). In eight patients, the effects of domperidone 10 mg iv and placebo were compared under random double blind conditions. Half emptying times were shortened significantly (p less than 0.01) by domperidone. Conclusions: symptoms of disordered upper gastrointestinal motor activity may be mistaken as indicating primary anorexia nervosa; clinical evaluation of patients with presumed primary anorexia nervosa should rule out the possibility that disordered oesophageal motor activity underlies the symptoms; delayed gastric emptying is a frequent feature in primary anorexia nervosa and might be returned to normal with domperidone.

Abstract: Several preclinical and clinical studies have documented that dose or dose intensity of chemotherapeutic agents are important factors for response of patients' tumors. This finding has prompted empiric trials of certain chemotherapeutic agents in high-dose or regional administration treatment regimens. The present study was performed to identify agents that would be particularly good candidates for high-dose or regional administration regimens against particular types of tumors. Using a human tumor cloning technique, we constructed dose in vitro response lines for ten different chemotherapeutic agents against seven different histologic types of malignancies. Slopes of the lines indicated the agents with the greatest increases of in vitro response per increment in dose of the agent. Tumors against which the agents gave the steepest dose response lines included lymphoma, head and neck cancer, ovarian cancer, and small-cell lung cancer, while the dose response lines for non-small-cell lung cancer, breast cancer, and colon cancer were quite flat. Suggestions for clinical trials based on these findings include the use of high-dose melphalan for patients with lymphoma, head and neck, and ovarian cancer; the use of mitoxantrone in high-dose regimens for patients with breast cancer; high-dose cisplatin regimens for patients with small-cell lung cancer; high-dose bleomycin regimens for patients with non-small-cell lung and head and neck cancer; and regional perfusion of liver metastases from colorectal cancer with cisplatin. Prospective testing of high-dose or regional administration regimens suggested by this new model should indicate its use for prediction of the best agent to use in high-dose regimens against a particular tumor type.

Abstract: Yersinia enterocolitica was cultured from feces of 122 symptomatic adults in a single facility using selective culture media; all isolates were confirmed in an independent reference laboratory. Of 128 isolates, multiple serotypes were defined and all were biochemically typical for Yersinia enterocolitica. Other agents were seen in 20 patients; of these, seven were Yersinia fredriksenii and six were Clostridium difficile. Diarrhea (80%) and abdominal pain (64%) were common, whereas other features such as fever (9%) and bloody stools (8%) were unusual. Use of antibiotics (24%) or opiates (28%) in the month before culture was common. The terminal ileum was seen radiographically in 20 patients, but only two barium studies showed abnormalities. Fiberoptic endoscopy and biopsy studies, done in greater than 50% of the cases, showed minimal or no changes in most patients. However, 3 patients had pseudomembranous colitis with concomitant Clostridium difficile cytotoxin and 7 had diffuse severe colitis. New culture techniques, and possibly geographic differences, have contributed to the high isolation rates of this organism. Yersinia enterocolitica occurs sporadically, involves a variety of serotypes, and is associated with a broader clinical spectrum than was formerly appreciated.
