Celiac disease (CD) is an immune-based reaction to dietary gluten. CD can present with a diverse array of symptoms. Many CD patients have no symptoms at all. Thus, a great number of atypical cases of CD remain undiagnosed, leading to a risk of long-term complications. Some atypical symptoms of CD such as pregnancy complications, infertility, recurrent abortions, intrauterine growth restriction, preterm delivery, and severe preeclampsia have been investigated in undiagnosed and diagnosed pregnant women with CD. Nutrient deficiency and autoimmune pathogenic mechanisms have been hypothesized to be the explanation of these adverse pregnancy outcomes. Recently, an association between obstetric complications and anti-tissue transglutaminase antibodies titers in women with CD has been reported. While the adverse effects of CD on the reproductive system are well investigated, there are only a few reports in the literature on the effect of pregnancy and puerperium on CD. We reviewed the published literature on the adverse effects and pathophysiology of CD in reproductive disorders and the effect of pregnancy and puerperium on the manifestation of CD.

Background: Open access gastroscopy allows physicians to refer patients for endoscopic procedures without a prior consultation.

Objectives: To compare the safety and efficacy of OAG[1] with gastroscopy performed after a gastroenterological consultation.

Methods: Patients referred for gastroscopy directly (open access) or after consultation with a gastroenterologist, by physicians in the departments of internal medicine and surgery at a major tertiary center, were compared for indications, background disease, outcome and diagnostic yield. The data were collected prospectively over a 5 month period following the introduction of OAG at the center. Physicians in both departments participated in an education program on the indications and procedure of gastroscopy. For each patient referred for OAG the attending physician completed a specially designed questionnaire that had to be signed by a senior physician. Data were managed and analyzed with Excel and SPSS software.

Results: The study sample comprised 494 patients: of whom 236 were referred for OAG and 258 after prior consultation. On multivariate analysis, hospitalization in the department of internal medicine was the only independent factor for OAG. Severe background disease and aspirin treatment had no effect on physician use of OAG, although they served as a “red light” for the gastroenterology consultants. There was no difference in the diagnostic yield of the procedures (26.4% normal findings for OAG and 28.3% for consultations) or in mortality rates. The main indications for referral to gastroscopy in the surgery department were melena, hematemesis, and "coffee grounds," and anemia and vomiting in the internal medicine department.
Conclusions: OAG is feasible and beneficial in an academic medical center setting, with no bias in appropriateness of indications or decrease in the diagnostic yield compared to the traditional approach. More attention should be directed to safety issues by the referring physicians

Background: The ¹³C-urea breath test is the best non-invasive test to validate Helicobacter pylori eradication. Serology is unreliable for this purpose due to the slow and unpredictable decline in the antibodies titer.

Objectives: To characterize a specific group of patients who were treated for H. pylori and tested for successful eradication by ¹³C-UBT[1] in our central laboratory and to correlate the eradication success rate with specific drug combinations, and to evaluate other factors that may influence eradication success.

Methods: ¹³C-UBT for H. pylori was performed in the central laboratory of Clalit Health Services. The breath test was performed by dedicated nurses in 25 regional laboratories and the samples were analyzed by a mass spectrometer (Analytical Precision 2003, UK). The physician who ordered the test completed a questionnaire computing demographic data (age, gender, origin), indication, use of non-steroidal anti-inflammatory drugs or proton pump inhibitor, and combination of eradication therapy.

Results: Of the 1,986 patients tested to validate successful H. pylori eradication, 539 (27%) had a positive test (treatment failure group) and 1,447 (73%) had a negative test (successful treatment group). Male gender, older age and European-American origin predicted better eradication rates. Dyspeptic symptoms and chronic PPI[2] therapy predicted treatment failure. Combination therapy that included clarithromycin had a higher eradication rate than a combination containing metronidazole. The combination of omeprazole, amoxicillin and clarithromycin achieved an eradication rate of 81.3%, which was better than the combination of omeprazole, metronidazole and clarithromycin (77.2%) (not significant), or of omeprazole, amoxicillin and metronidazole (66.1%) (P < 0.01).

Conclusion: Gender, age, origin, dyspepsia and PPI therapy may predict H. pylori eradication results. Our findings also support an increase in metronidazole resistance of H. pylori strains in Israel, as described in other countries. We recommend combination therapy with omeprazole, amoxicillin and clarithromycin and avoidance of metronidazole as one of the first-line eradication drugs.
