Helicobacter pylori (HP) is the most common cause of nonerosive nonspecific gastritis. Gastric and duadenal ulcer both are found to be associated with HP infection. Another consequence of HP infection is that it may progress to chronic atrophic gastritis which is a well recognized risk factor for adenocarcinoma of the stomach. So by extension, HP infection can be accepted as a risk factor for gastric cancer. From this aspect, identification of risk groups is increasingly important. It is well-known that patients with diabetes mellitus are more prone to infection. Besides this, presence of gastroparesis diabeticorum may lead to bacterial overgrowth in the upper gastrointestinal (GI) tract. The present crossectional study was planned to study the presence of HP infection in diabetic patients with alterations in upper GI motility and to compare the results with healthy control group. Group I consisted of 51 patients with type II diabetes mellitus (as defined by National Data Group criteria) without any dyspeptic symptoms. Twenty-five age-matched healthy people served as a control in group II. Radionuclide-labelled solid meals were used to calculate gastric emptying time (GET). According to the results, patients in group I were divided into two groups. Patients with prolonged GET were grouped as group IA, while group IB consisted of patients with normal or shortened GET. Presence of HP gastritis is determined by histopathologic examination of endoscopic biopsy specimen. The results showed that the prevalence of HP gastritis in group I and II were 80.4% and 56% respectively and the difference was significant statistically (p: 0.03). In group IA, the prevalence of HP infection was estimated to be 88.2%, while in group IB it was 76.5% but the difference was not significant (p: 0.31). We have not found any correlation between HbA1c levels and the presence of HP infection in both group IA and IB (p values 0.26 and 0.15 respectively). We conclude that the prevalence of HP gastritis is higher in asymptomatic diabetic patients compared with healthy people. But there is no association between the alterations in GET and the presence of HP gastritis as indicated by our results. So prolonged GET may not be regarded as a specific pathogenic mechanism or a cause of HP infection in NIDDM patients.

Long-term follow-up was performed 16 to 26 years after conservative (group I, n = 18) and operative (group II, n = 38) treatment of 56 patients who had infantile hypertrophic pyloric stenosis (IHPS). The study encompassed the scintigraphic determination of gastric emptying rates for solids and liquids, an interview to obtain medical history and ascertain whether a current disorder of the upper gastrointestinal tract was present, and a clinical examination. Gastric emptying rates were measured on two different days for solids and liquids. The standard solid meal consisted of two scrambled eggs, two slices of toast, and 20 g of margarine. The gastric emptying rate for liquids was measured using 300 mL of apple juice. The scrambled eggs and apple juice were each marked with 2.2 MBq technetium 99m-sulphur-colloid. Two control collectives were used in this study; one group (physicians) served to create a reference curve for gastric emptying, and the other group, with the same age and gender distributions as those of the patients, served to evaluate the frequency of gastrointestinal complaints, by means of a questionnaire. There was no significant rate difference for gastric emptying between the patients treated conservatively or surgically and the controls. No association could be construed between the frequency of gastrointestinal symptoms or disorders and the gastric emptying rates for solids and liquids. The results presented here substantiate that clinically relevant disturbances of stomach motility after IHPS appear to be rare.

Liquid elimination function of the stomach was studied in 41 patients and 9 normal subjects by using SPECT technique. The result suggested that six kinds of the liquid elimination curve of stomach can be classified. Patients with chronic gastritis and peptic ulcer mostly were kinds of slow elimination (1) and (2). Normal subjects mostly were kind of (6). The pathophysiologic significance of six kinds liquid elimination pattern needs further research.

Even though Ga-67 imaging has been used widely in the diagnosis of malignant as well as inflammatory lesions, its uptake in the stomach has been reported in the literature mainly in gastric lymphoma and carcinoma. As shown in this case, intense gastric uptake of the radionuclide may be seen in common gastritis without malignancy. Perhaps the benign gastric uptake of Ga-67 deserves more emphasis.
