A total of 276 patients with taeniasis alone and taeniasis associated with enterobiasis or lambliasis were involved in the study. The most prevalent features in patients of all the three groups were combinations of the painful, dyspeptic and astheno-vegetative syndromes, the least so--an isolated astheno-vegetative syndrome. Combinations of these syndromes more frequently occur in taeniasis concomitant with enterobiasis (61% vs. 51% in taeniasis alone). Associations of taeniasis with enterobiasis or lambliasis are more frequently diagnosed in children. Combinations of the three syndromes were revealed in the patients with taeniasis coursing against the background of chronic gastritis, duodenal ulcer, cholepathies: in 79% vs. 33.3% in an uncomplicated course. Fenasal therapy for 3 days in a daily dose of 3 g proved fairly effective: 85.7 +/- 6.3% of adults and 82.6 +/- 6.4% of children recovered.

Two cases of chronic giardiasis of the stomach diagnosed from gastric mucosal biopsy specimens are reported. The first case was associated with an acute-on-chronic gastritis and Helicobacter-like organisms, and the second with an adenocarcinoma of the stomach. In both cases the trophozoites had been missed in earlier biopsy specimens. As far as is known this is the first report of giardiasis of the stomach.

A patient with giardiasis in an inflamed gastric antral biopsy specimen is reported. Helicobacter pylori were not identified and no other cause of the gastritis was apparent. This condition may be more common than has been previously supposed and may be linked to bile reflux or hypochlorhydria.

Information is limited concerning the prevalence of Helicobacter pylori infection in asymptomatic children. Since January 1989, we have endoscoped 60 children for recurrent abdominal pain or for obtaining small-intestinal biopsy (their ages were a mean of 6.6 (range 9 months-13 years); there were 37 boys and 23 girls. Antral biopsies were obtained from all subjects and these were studied for the presence of gastritis and stained for H. pylori using modified Gram's stain. All biopsies were cultured for H. pylori. Children endoscoped for small-intestinal biopsy (n = 18) were used for comparison. Of the 42 children who had abdominal pain, 24 showed histological gastritis and 13 had H. pylori on microscopy (31% H. pylori-associated gastritis). In the compared group, five showed histological gastritis, and all had H. pylori on microscopy (27.7%). Culture was positive in 15; sensitivity was 85.7%. Six children, three pairs of siblings, had H. pylori gastritis supporting environmental etiology. Two had coinfection with intestinal giardiasis. Seven children were treated with daily oral amoxycillin (50 mg/kg) and tinidazole (20 mg/kg) for 6 weeks. In 3 (42.3%) H. pylori colonization cleared with healing of gastritis and resolution of symptoms. These results indicate that H. pylori gastritis is equally prevalent in symptomatic and asymptomatic children (31 and 27.7%, respectively; p > 0.05) in our population. It seems that the combination of oral amoxycillin and tinidazole is a poor choice in the treatment of H. pylori-associated gastritis in Kuwaiti children.

One hundred and two patients suffering from giardiasis and/or chronic gastritis were subjected for upper gastrointestinal endoscopy. Purified immune rabbit's serum against Giardia lamblia was used in ELISA and immunoperoxidase (IIP) techniques for detection of Giardia antigen in the stomach. Results showed that out of 70 cases with intestinal giardiasis, 8 (11.4%) by ELISA and 6 (8.6%) by IIP showed gastric giardiasis. Higher percentage of gastric giardiasis (14%) was encountered in cases with both giardiasis and chronic gastritis (50) than in cases with giardiasis alone (5%) but with statistically insignificant difference (P > 0.05). None of the cases with chronic gastritis alone (without giardiasis) was positive for gastric giardiasis. Dyspepsia was the main presenting symptom in cases with gastric giardiasis (P < 0.05) with significant (P < 0.05) association. Helicobacter pylori was encountered in 6 out of 8 cases (75%) with gastric giardiasis (P < 0.05) with significant (P < 0.05) association. Duodenogastric reflux was detected in 4 out of 8 cases (50%). Histopathological changes in antral mucosa were detected in all cases of gastric giardiasis. This study indicates that under abnormal circumstances most probably with decreased gastric acidity, gastric giardiasis can occur in concomitance with intestinal giardiasis. So, one has to search for Giardia in gastric biopsies, particularly those showing chronic atrophic gastritis and H. pylori. Also, one has to be aware of gastric giardiasis as a possible cause of upper gastrointestinal symptoms.

Helicobacter pylori (Hp) gastritis is a worldwide problem significantly associated with duodenal and gastric peptic ulcer disease, gastric carcinomas, and MALT-type lymphomas. A simple, rapid, reproducible, reliable, and inexpensive stain to detect the organism in gastric biopsy specimens is thus of great value. To assess the reliability and cost-effectiveness of a novel Alcian yellow-toluidine blue (Leung) stain for Hp, we stained 60 endoscopic mucosal biopsy specimens from patients with Hp gastritis and measured time to detection of organism, Hp numbers (scale, 1-5), and technical costs. We also stained serial 5-microm step sections of 17 of these cases with the Giemsa and modified Steiner (MS) methods, and similar measurements were made. Also, specimens from various normal gastrointestinal sites and metaplastic lesions, as well as four cases each of giardiasis and cryptosporidiosis, were stained with the Leung method. In the subset of 17 cases, the Leung stain enhanced detection time and compared favorably with the Giemsa method, though the MS method was somewhat superior. Hp scores were similar among all groups. Mean time to detection and Hp scores were similar in the larger (n = 60) group stained with hematoxylin and eosin and the Leung stain. Material costs and technologist's time for Giemsa stains, however, were greater than for the Leung stain, and technologist's time for MS was nearly fourfold that of the Leung stain. With the Leung method, mucus from all gastrointestinal sites and metaplastic lesions stained yellow, and this stain provided excellent contrast and morphologic definition in giardiasis and cryptosporidiosis. We suggest that the newly developed Alcian yellow-toluidine blue (Leung) histochemical stain is a good choice as the standard for routine Hp staining because it is the cheapest and easiest to prepare and because pathologists' detection with this stain compares favorably with detection times achieved with more traditional and established methods.

Thirty patients treated with proton pump inhibitor and still having symptoms related to gastritis or peptic ulcers were subjected to upper gastrointestinal endoscopy and gastric biopsy for detection of giardiasis in these cases. Results showed presence of 3 (10%) cases of gastric giardiasis, intestinal metaplasia and presence of H. pylori in these cases. It is concluded that there may be a relation between the presence of gastric giardiasis and the intake of proton pump inhibitor. The endoscopists have to search for gastric giardiasis especially in the presence of H. pylori and/or intestinal metaplasia.

Chronic gastritis and intestinal metaplasia associated with naturally occurring colonization by Helicobacter aurati and two other microaerobic species were observed in Syrian hamsters. Thirty-five hamsters, between 7 and 12 months of age, were evaluated from two research and three commercial facilities. Microaerobic bacteria were cultured from the hamster stomachs. These bacteria included H. aurati, a fusiform, urease-positive species; a second novel helical, urease-negative Helicobacter sp.; as well as a smaller, urease-negative Campylobacter sp. Southern blot analysis detected Helicobacter spp. DNA in the gastric tissues of all 35 hamsters; 15 hamsters also had Campylobacter sp. DNA in their gastric tissues. When examined by light microscopy, argyrophilic bacteria consistent with H. aurati or the second Helicobacter sp. were present in antral sections of 12 out of the 15 hamsters where bacteria were seen, while 9 out of the 15 hamsters had bacteria resembling the Campylobacter sp. The presence of Helicobacter spp. but not the presence of Campylobacter sp. was significantly correlated to gastritis severity (P < 0.0001 for Helicobacter spp., P = 0.6025 for Campylobacter sp.) and intestinal metaplasia, as measured by numbers of goblet cells (P = 0.0239 for Helicobacter spp., P = 0.5525 for Campylobacter sp.). Severely affected hamsters also had Giardia sp. within their metaplastic gastric pits. Hamsters with naturally occurring helicobacter-associated gastritis provide a model for studying the development of intestinal metaplasia and gastric giardiasis in H. pylori-infected humans.

A 56 year-old male patient had a gastric resection (Billroth II) at age 33. In 1993 he had vague upper digestive complaints. During investigations for a moderate anaemia biopsies performed during an oesogastroduodenoscopy revealed a jejunitis with Giardia lamblia (G.l.) trophozoites which were also found on the gastric mucosa associated with Helicobacter pylori related chronic active gastritis. The few publications dealing with the presence of Giardia lamblia in the stomach either assert or cast some doubts on the pathogenicity of this protozoa for the gastric mucosa. Gastric involvement by G.l. is usually associated with duodeno-jejunal disease responsible for diarrhoea which may occur as epidemics of varying extension. Since Giardia lamblia infection is not submitted to reporting in Switzerland, the epidemiology in our country is scarcely known and investigated. In our opinion, however, health authorities in Switzerland should consider the need of reporting this infectious disease.

Eighty five children with recurrent abdominal pain(RAP) were studied. Organic cause was noticed in 70 cases and non-organic in 15 cases. Giardiasis was the commonest organic cause in 57 (67.0 percent), either alone or with other parasitic infestations. Other organic causes include gallstones (4.7 percent), urinary infections (4.7 percent), esophagitis/gastritis (3.5 percent) and abdominal tuberculosis (2.3 percent). Single parent, school phobia, sibling rivalry, RAP in other family members and nocturnal enuresis are significant factors associated with nonorganic causes
