Prolonged cimetidine therapy in ulcerated Barrett's columnar-lined esophagus.

In a 77-year-old man with dysphagia, x-rays demonstrated an irregular stenotic process in the lower third of the esophagus, suggesting malignancy. Endoscopy disclosed moderate narrowing of the lumen and several ulcers separated by bulges. Serial biopsies revealed Barrett's mucosa. Cimetidine 1 g/day led to prompt improvement and endoscopically there was a disappearance of the lesions after 3 months of therapy. Reduction of the drug to 400 mg/day 3 months later with supplements of antacids and metoclopramide was followed by reappearance of symptoms and recurrence of a deep ulcer. Raising the dose of cimetidine to 1 g/day again resulted in healing and since then a maintenance dose of 600 mg cimetidine with antacids and metoclopramide has been successful in preventing recurrence. This long-term study in a patient with Barrett's esophagus showed 1) that cimetidine can be effective in treating such patients; 2) the prophylactic value of multitherapy as a maintenance regimen, and 3) the importance of careful follow-up.

New therapeutic approach in postoperative phytobezoars.

Postoperative phytobezoars (duration from 2 months to 46 years) after surgery for duodenal ulcer disappeared in seven patients, by both x-ray and gastroscopy, on conservative approach aimed at the major role of delayed gastric emptying in phytobezoar formation. During a 3-day period, metoclopramide was given by drip infusion, 40 mg/24 hours, and the patient received only a copious clear diet, with no solid food. In one patient, two courses of treatment were necessary for complete elimination of the phytobezoar. None of the patients had any underlying disease. All but one had good dentition. "Disruption" of the bezoars allowed the discovery upon endoscopy of unusual etiological features such as carcinoma of the stoma and stomal polypoid hypertrophic gastritis (so-called gastritis cystica polyposa ) in one patient, and a retained suture narrowing the stoma in another.

Intrasinusoidal metastatic melanoma of the liver with reactive hepatitis. An immunologic phenomenon?

The macrophage migration inhibition factor (MIF) test toward extracts of choroidal melanoma was repeated four times in a patient with ocular malignant melanoma. In the initial stage, when there was only an ocular finding, the MIF test result was positive. It remained so for a period of two years, even when intrasinusoidal hepatic diffusion developed concomitantly with a nonspecific reactive hepatitis. These histologic findings can be interpreted as evidence of the presence of an immune reaction at a particular moment in the disease process. Several months later, when the patient's condition went into an abrupt decline and showed extensive nodular spread, the results of MIF test were found to have become negative.

Basal cell carcinomas, gastrointestinal carcinomas, and ulcerative colitis in relation to the disappearance of a plasma factor.

Our previous findings have shown that the plasma of cancer patients lacks a factor (LCMEF) that is characterized by its ability to enhance lymphocytic cortisol metabolism. In the present study we have examined whether this phenomenon also appears in patients suffering from basal cell carcinoma, a seldom metastasizing disease, and in patients with ulcerative colitis regarded to be at high risk of developing cancer. Known concentrations of human lymphocytes from healthy donors were incubated with cortisol in media containing 50% phosphate-buffered saline (PBS) and 50% of one of the following additions: 1) homologous plasma, 2) plasma from the patients being tested, or 3) additional PBS. Previous findings showed that the plasma of cancer patients has a mean metabolism-enhancing rate of 62% of that obtained with homologous plasma. In the present work the results were as follows: basal cell carcinomas--98%, gastrointestinal carcinomas--63%, ulcerative colitis--95%, and healthy donors--90%. The results with regard to cancer patients show that lack of LCMEF does not characterize basal cell carcinoma and ulcerative colitis. Hence, it is possible that the disappearance of LCMEF 1) does not characterize ulcerative colitis as long as a malignant tumor does not appear and 2) does not characterize seldom metastasizing disease (basal cell carcinoma).

Evaluation of prajmalium-induced cholestasis by immunologic tests.

Cholestatic jaundice developed in four patients after the administration of prajmalium bitartrate. The clinical, histologic, ultrastructural, and immunologic findings were determined. In all patients, the clinical and morphologic features indicated idiosyncrasy. Two antibodies distributed in a granular pattern along the bile canaliculi were detected by immunofluorescence in all patients. In one patient, autoimmune markers were found in the serum, and in two instances, the migration-inhibition factor assay against the offending drug was found to be positive. The data support the concept that immunologic processes may participate in the production of the cholestatic syndrome.

Candidal infection of benign gastric ulcers in aged patients.

In seven elderly patients with benign gastric ulcer, numerous spores and mycelia of Candida were found in the inflammatory exudate and in the base of the ulcer. All patients were treated with cimetidine and antacids. In five patients the ulcer failed to heal. Cimetidine was replaced with mycostatin and after four weeks of treatment, the ulcers healed completely in four patients. It is assumed that in the elderly, due to the weakening of the host defense mechanisms, Candida may invade the base of the ulcer and disturb the normal process of healing.
