Background: Peripheral neuropathies (PN) and primary headaches (PH) are common comorbidities in inflammatory bowel disease (IBD) patients. We aimed to evaluate whether PN and PH affect the same subgroups of IBD patients.
Methods: Since 2004, we established a cohort study to evaluate neurological diseases in IBD patients.

Article Synopsis
- Helicobacter pylori is linked to chronic gastric inflammation and increases the risk of duodenal and gastric ulcers, as well as gastric cancer.
- This study assessed H. pylori genotypes in 134 Brazilian patients with varied gastric conditions, finding the s1m1 vacA variant was most common and associated with more severe diseases.
- The presence of the cagA gene and mixed vacA strains were significantly linked to gastric cancer and peptic ulcers, indicating that more virulent H. pylori strains are prevalent in regions with high gastric cancer rates in northeastern Brazil.
