A 71-year-old man with characteristic clinical and pathological pictures of Cronkhite-Canada syndrome associated with gastric cancer is presented. Histological examinations of gastric and colonic polyps which resembled juvenile type revealed no malignant cells. The patient slowly recovered after subtotal gastrectomy and elemental diet supplement with antiplasmin agents. As for as is known to the authors, a total of 69 cases with this syndrome were reported in Japan including our patient. Of these cases 8 had cancer of the gastrointestinal tract. Two of them, including our case, had gastric cancer. Another one was associated with gastric cancer but not intestinal polyposis. The remaining 5 cases were associated with colonic cancer. Caution must be paid to the fact that cachexia or malabsorption in some patients with this syndrome results from gastrointestinal malignancy. The prognosis of this syndrome consisted of 20 deaths including 2 postoperative deaths, 33 of improvement including 4 of natural remission and 4 of remission after gastrectomy or colectomy, 7 unchanged and the remainder not described.

A malignant lymphoma of the small bowel developed in a 75-year-old woman who had severe late-onset hypogammaglobulinemia with intestinal malabsorption and nodular lymphoid hyperplasia. The tumor arose in the midst of the abnormal lymphoid follicles and appeared to be of B-immunoblastic type. Immunoperoxidase staining, however, failed to reveal immunoglobulins in the tumor cells. In vitro immunologic studies showed that immunoglobulin production by the patient's peripheral lymphocytes had decreased and that this decrease was mediated by hydrocortisone-sensitive suppressor cells. These findings suggest that nodular lymphoid hyperplasia of the intestine in the context of severe immunodeficiency is a premalignant condition.

The absorption of oral methotrexate (MTX) has been studied in 124 children with acute lymphoblastic leukemia (ALL). Blood levels of MTX were very variable and unpredictable. There was a 20-fold difference between the highest and lowest peak level achieved. Division into two groups has shown that those children who absorb MTX slowly have a worse disease-free survival. It is possible that MTX damages the intestinal mucosa and causes a malabsorption of itself in some children. It is suggested that future protocols for the treatment of ALL should include pharmacokinetic studies, which may help to explain the unexpected relapses of good prognosis patients and lead to the development of more effective treatment.

Coeliac disease is a permanent food intolerance with a genetic basis which persists throughout the whole life. Ingestion of gluten proteins (wheat, rye, barley, oats) causes atrophy of the jejunal villi and, as a consequence, malabsorption. Diagnosis can only be proved by three consecutive intestinal biopsies; initially on normal diet, after 12--18 months of gluten-free diet, and after a final challenge with gluten-containing food. Biochemical changes have been discussed for a long time to be of primary importance in the pathogenesis of coeliac disease. Recently, however, evidence is increasing that immunological mechanisms are primary factors in the development of the disease. A synopsis of biochemical and immunological phenomena and of membrane receptor alterations of enterocytes and immunocytes which are genetically based is more likely to answer the question of pathogenesis than any single theory. Therapeutically, life-long gluten-free diet is necessary. In some cases, after a long course the prognosis is limited by the increased incidence of malignancy.

Glucose Tolerance Factor (GTF) is synthesized in vivo from absorbed dietary chromium, and acts as a physiological enhancer of insulin activity, binding to insulin and potentiating its action about three-fold. Since GTF is well absorbed orally, the development of sufficiently concentrated and stable supplementary sources of this agent may enable convenient and physiologically appropriate pharmacological modulation of insulin activity. A review of the numerous physiological actions of insulin suggests a number of therapeutic applications for GTF, in such diverse ailments as diabetes mellitus, hyperlipidemia, reactive hypoglycemia, obesity, cancer, protein malnutrition or malabsorption, endogenous depression, Parkinsonism, hypertension and cardiac arrhythmias. GTF supplementation may also have value in preventive medicine.

Coccidia were found in a patient suffering from malabsorption syndrome. In addition, immunologic investigation showed combined humoral and cellular immunodeficiency. Treatment with metronidazole induced the disappearance of coccidia from the stool and clinical remission. Six months later, the patient was seen with acute lymphoproliferative disease and died thereafter. The possible relationship between malabsorption, immunodeficiency, coccidiosis, metronidazole, and malignancy is reviewed.

To determine whether lactose malabsorption can be induced in children receiving cancer chemotherapy, lactose breath hydrogen tests (LBHT) were performed on 27 patients (ages 2 months to 16 10/12 years, mean 4 3/12 years) with neoplastic disease. Nine patients had an LBHT before their first course of chemotherapy and then 7--26 days afterwards. Eighteen other patients, less than 5 years old and presumed by virtue of age to be normal lactose absorbers, had an LBHT 7--24 days after their last course of chemotherapy. All nine in the first group had a normal LBHT before chemotherapy, and three had an abnormal LBHT 7--21 days later. Six of eighteen patients in the second group had an abnormal LBHT. Of the nine patients with an abnormal LBHT, six had a history of diarrhea associated with chemotherapy. These findings have important implications for children receiving cancer chemotherapy. High-calorie, milk-containing solutions used in nutritional support may precipitate cramps and diarrhea in some of these patients. A therapeutic trial of a low lactose diet in children in whom diarrhea develops during chemotherapy may be indicated.

In a group of cancer patients selected to exclude common causes of abnormal lipid absorption, we have examined this function using a breath test. Abnormal breath tests of fatty acid absorption (FABT) are found in most cancer patients, as has been previously claimed. These tests are abnormal in both quality (delayed peak in nine of ten patients, and quantity (reduced maximum peak in five of ten patients) of fatty acid absorption. In many patients abnormal FABT is not due to chemotherapy. Our preliminary results indicate no definite malabsorption mechanism but more stringent tests of absorption need to be applied. Malnutrition is common in cancer patients, even in those with little or no weight loss, and some of the malnutrition may be related to abnormal lipid absorption or to other disturbed aspects of lipid metabolism.

Fatty acid absorption breath tests (FABT) were found to be abnormal in most subjects in a group of cancer patients selected to exclude common causes of abnormal lipid absorption, including chemotherapy and radiation therapy. The breath tests were abnormal in both quality (delayed peak in 9 of 10 patients) and quantity (reduced maximum peak in 5 of 10 patients) of fatty acid absorption. Retrospective separation of patients into 2 groups (normal or low maximum peak height FABT), either at a common time after the start of the test or at each individual's maximum peak height FABT regardless of time, was significant at 0.005 and 0.001, respectively. The low maximum peak heights were in the range of the malabsorption syndrome. Further studies of pancreatic function and fat malabsorption are warranted before the abnormal results can be ascribed to altered intermediary metabolism or peripheral utilization of lipids.

Fifty cases of histologically proven intestinal tuberculosis are presented. Although intestinal tuberculosis is declining in Iraq, it is still a common condition affecting the bowel. Most of the lesions were primary and usually of bovine origin. The peak age incidence was between 30-39 years. Sexes were equally affected. The clinical presentation is usually intestinal obstruction, less commonly abdominal malignancy, malabsorption, or appendicular mass. All patients were explored and resection was carried out in 40; all were given antituberculous chemotherapy. The results are very satisfactory in the 47 patients that continued chemotherapy for over one year.
