Smoking and Gastro-oesophageal Reflux

Gastro-oesophageal sphincter pressure and intraoesophageal pH has been studied in 25 chronic smokers who complained of heartburn. Smoking a cigarette invariably caused a fall in sphincter pressure, and pH measurements showed an increased tendency for reflux to occur while smoking. When lower oesophageal pH was measured overnight one-third of all reflux episodes occurred while the patients were smoking, and reflux was seen during the smoking of two-thirds of all the cigarettes consumed. It is concluded that cigarette smoking is a common reversible cause of gastro-oesophageal reflux.     

Neurological Disease after Partial Gastrectomy

Clinical and laboratory signs of neurological disease were found in 14 patients many years after partial gastrectomy. Vitamin B₁₂ deficiency occurred in most patients, but only those three who had signs of subacute combined degeneration of the cord and no osteomalacia responded well to treatment.     

Iron-Deficiency Anemia After Partial Gastrectomy

Although the mechanism for its development is not well understood, iron-deficiency anemia is a well-recognized consequence of partial gastrectomy. The reported incidence varies considerably, depending upon the criteria used to define anemia, and other factors. Rapid emptying of the gastric remnant, intestinal “hurry”, and borderline dietary-iron intake, with or without concomitant blood loss, produce malabsorption of some forms of iron that appears to be responsible for development of the deficiency. The diagnosis rests on hematological findings in the peripheral blood, the evaluation of iron stores, epithelial changes, and the response to adequate treatment. Oral iron therapy can be both effective and inexpensive and should form the mainstay of treatment.
