Whether or not the eradication of Helicobacter pylori is a risk factor for reflux esophagitis (RE) is a question at issue. To find an answer, it is necessary to clarify the influence of H. pylori eradication on the mechanism of RE. ⋯ The cure of H. pylori infection does not, by itself, cause RE in patients who have few other risk factors for RE.

Superparamagnetic iron oxide-enhanced MR imaging for focal hepatic lesions: a comparison with CT during arterioportography plus CT during hepatic arteriography.
We aimed to evaluate the efficacy of a breath-hold superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance (MR) imaging protocol for the detection of focal hepatic lesions, in comparison with a non-breath-hold SPIO-enhanced imaging protocol and computed tomography during arterioportography (CTAP) plus CT during hepatic arteriography (CTHA). ⋯ As a preoperative test, SPIO-enhanced MR imaging could have the potential to replace CTAP plus CTHA in a certain clinical setting.

Kaposi's sarcoma is an uncommon neoplasm that occasionally involves the gastrointestinal tract in immunosuppressed individuals. Infection with human herpes virus 8 is known to be necessary for developing all forms of Kaposi's sarcoma. We report a renal transplant recipient who developed visceral Kaposi's sarcoma 18 months after the transplantation. ⋯ Standard forceps biopsies of the gastric lesions failed to make the correct diagnosis. However, endoscopic resection successfully led to the correct diagnosis of Kaposi's sarcoma and herpes simplex virus 8 infection as well. This is the first report of a patient with visceral Kaposi's sarcoma who underwent endoscopic resection that reliably confirmed histological diagnosis and the viral genome at the same time.

Infection with Helicobacter pylori has been associated with chronic idiopathic urticaria (CIU). The aim of this study was to investigate the efficacy of H. pylori eradication in the treatment of patients with CIU. ⋯ Eradication of H. pylori would be a valid choice for patients with CIU, although the prevalence of H. pylori infection is not higher in patients with CIU than it is in controls.
