[Excretion of nitrates with saliva and urine and nitrite excretion with saliva in patients with chronic gastritis and duodenal ulcer].

The study assessed excretion of nitrates in urine and saliva and that of nitrites with saliva of patients suffering gastric and duodenal ulcer. In both study groups, a positive correlation was established between nitrate concentration in saliva, on the one hand, and that in urine, and nitrite level in urine, on the other. The groups failed to show a difference in nitrate concentrations in either urine or saliva. Since retention of nitrates in the body of chronic gastritis patients held as precancer of the stomach proved no higher than that in patients with duodenal ulcer, the authors cast doubt on endogenous nitroso compounds as a cause of gastric cancer in cases of chronic gastritis.

[Errors in the diagnosis of peptic ulcer].

The diagnosis made at the polyclinics and at the gastroenterology clinic were studied and compared. There were 2515 patients admitted to or discharged from hospital with a diagnosis of peptic ulcer. In gastric ulcer (630 patients), the erroneous diagnoses accounted for 24.8 +/- 1.1% including 7.7 +/- 0.7% of cases undiagnosed at the polyclinics and 17.0 +/- 1.0% of cases with an overdiagnosis. In duodenal ulcer, the respective figures were 15.1 +/- 0.6, 5.7 +/- 0.4 and 9.3 +/- 0.5%. The level of gastric ulcer diagnosis was lower than that of duodenal ulcer (p less than 0.01), the rate of overdiagnoses in both cases was, respectively 2.2- and 1.6-fold higher than that of underdiagnoses. The erroneous diagnoses mostly fall within faulty ulcer localization, chronic gastritis, chronic duodenitis, and chronic biliary diseases. Three groups of factors were distinguished among the causes of errors in the diagnosis of peptic ulcer: underestimation by the physicians of the pathomorphism and changed symptomatology; erroneous assessment of the disease history and examination data; not taking into sufficient account of the disease course determined by the sex, age and polymorbidity of the today's patient. The causes of errors were not infrequently found to go together.
