BACKGROUND Sugar-rich foods are of the main components of daily human meals. These foods with high sugar and low water content kill bacteria. However, osmotolerant yeasts survive and multiply. The aim of this study was to examine the occurrence of intracellular Helicobacter pylori (H. pylori) and Staphylococcus spp. in yeast isolates from sugar-rich foods. METHODS Thirty-two yeast isolates from fresh fruits, dried fruits, commercial foods, and miscellaneous foods were identified by the sequencing of amplified products of 26S rDNA. Fluorescence microscopy and LIVE/DEAD bacterial viability kit were used to examine the occurrence of live bacteria inside the yeast's vacuole. Immunofluorescence assay was used to confirm the identity of intracellular bacteria as H. pylori and Staphylococcus . Polymerase chain reaction (PCR) was used for the detection of 16S rDNA of H. pylori and Staphylococcus in the total DNA of yeasts. RESULTS Yeasts were identified as members of seven genera; Candida, Saccharomyces, Zygosaccharomyces, Pichia, Meyerozyma, Metschnikowia, and Wickerhamomyces. Intravacuolar bacteria were stained green with a bacterial viability kit, revealing that they were alive. Immunofluorescence assay confirmed the identity of intracellular H. pylori and Staphylococcus spp. PCR results revealed that among the 32 isolated yeasts, 53% were H. pylori -positive, 6% were Staphylococcus -positive, 18.7% were positive for both, and 21.8% were negative for both. CONCLUSION Detection of H. pylori - and Staphylococcus -16S rDNA in yeast isolates from dried fruits, and commercial foods showed the occurrence of more than one kind of endosymbiotic bacterium in yeasts' vacuoles. While the establishment of H. pylori and Staphylococcus in yeast is a sophisticated survival strategy, yeast serves as a potent bacterial reservoir.BACKGROUND Functional gastrointestinal system diseases (FGIDs) are a group of childhood disorders, our knowledge of which is relatively limited. More importantly, the different subgroups among such a disease group are closely interrelated, and their natural courses and interrelations have yet to be fully clarified. Functional constipation and gastroesophageal reflux disease (GERD) are most frequently seen among this group. However, evidence as to whether any relationship exists between them is limited. In this study, we tried to examine the existence or absence of this relationship. METHODS First, patients with functional constipation were identified based on ROME III criteria, which included 205 patients. All patients were classified into two groups of 185 and 20 patients based on their ability to respond to the questions. Then age, sex, duration of constipation, treatment, and symptoms associated with reflux were examined based on the GERD questionnaire (in case group 185) and I-GERD (in case group 20). Scoctional constipation. In the present study, no significant relationship was found between Rome III criteria and reflux. CONCLUSION The frequency of GERD among cases with constipation was 14.1%. There was no significant relationship between Rome III criteria and reflux.BACKGROUND Multiple sclerosis (MS) is a chronic disease with significant morbidity. A wide spectrum of risk factors has been suggested that triggers the development of MS. Piceatannol purchase Among them, several viral infections have been implicated to play a role in MS pathogenesis. We aimed to evaluate the relationship between viral diseases, including Epstein-Barr virus (EBV), human herpes virus 6 (HHV-6), cytomegalovirus (CMV), and hepatitis B virus (HBV) and MS in the present case-control study. METHODS About 100 patients with confirmed MS and age- and sex-matched individuals were selected as case and control groups, respectively. The patients were randomly selected from individuals diagnosed by neurologists based on the clinical signs and symptoms and imaging procedures. RESULTS More than 100 patients with MS and patients who were referred for other causes were analyzed for the presence of DNA of EBV, HHV6, CMV, and HBV separately. 9.37% of the control group had a positive test for the DNA of EBV in a real-time polymerase chain reaction (PCR), while the frequency of positive test result was zero in the case group (p = 0.0012). HBV DNA was not detected in both the case and control groups. The prevalence of CMV was 0.88 and zero in the control and case groups, respectively (p = 0.3410). For HHV6, 9.73 % of the control group had a positive result, while this test was positive in 5.88% of the patients with MS (p = 0.2959). CONCLUSION We detected a significantly higher number of individuals with DNA of EBV in their blood among the control group compared with the case group. In conclusion, the results suggest a surprisingly adverse association between MS and EBV, and no association was found between the presence of DNA of HBV, CMV, and HHV6 and MS.BACKGROUND The Crohn's Disease Endoscopic Index of Severity (CDEIS) and the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) are two validated endoscopic scoring system to evaluate patients with inflammatory bowel diseases (IBD). We conducted this study to evaluate the correlation between clinical symptoms and lab tests with these indexes in patients with Crohn's disease (CD) and ulcerative colitis (UC). METHODS In this analytical study, 373 consecutive patients referred to Shahid Mohammadi Hospital with IBD were enrolled. All patients underwent complete ileocolonoscopy, and the endoscopic severity indexes (CDEIS and UCEIS) were calculated, and their relation with clinical symptoms and lab tests was evaluated. RESULTS Fever observed only in six patients (1.6%). It was associated with significantly higher CDEIS and UCEIS (p = 0.02 and p less then 0.001, respectively). Also, diarrhea was correlated with significantly higher UCEIS (p less then 0.001). The mean fecal calprotectin was 647.64 ± 409.37 µg/g in CD and 567.30 ± 342.49 µg/g in UC patients. Higher calprotectin level was observed in patients with higher CRP level (p = 0.001), erythrocyte sedimentation rate (ESR) level, CDEIS, and UCEIS (r = 0.438; 0.473; and 0.517; respectively, all with p less then 0.001). CONCLUSION Our study showed that although fever and diarrhea are associated with higher endoscopic severity scores in patients with IBD, no clinical symptom could reliably predict the endoscopic results, alone. Furthermore, higher fecal calprotectin level is associated with higher ESR and C reactive protein levels, CDEIS, and UCEIS.
