A cross-sectional study on the association between Helicobacter pylori infection and headache.

Background: The relationship between chronic Helicobacter pylori (HP) infection and headache has been discussed for long; nevertheless, the results of the studies are still contrasting.

Objective: This cross-sectional study is aimed to investigate a possible association between HP and headache, mainly migraine.

Methods: We screened, by a self-administered questionnaire, the subjects undergoing a breath test or an esophagogastroduodenoscopy.

Therapeutic ureteral occlusion with Ifabond cyanoacrylate glue: an interesting solution.

Objective: The aim of this study was to present a novel approach for complete and permanent ureteral occlusion using a percutaneous injection of Ifabond cyanoacrylate glue.

Methods: We describe in detail all the steps of our surgery, performed on a 79-year-old patient with urinary leakage from ureteral stump following radical cystectomy. N-hexyl-cyanoacrylate glue (Ifabond) was used to occlude the distal ureter and solve the leakage.

Intrasinusoidal bone marrow infiltration and splenic marginal zone lymphoma: a quantitative study.

Intrasinusoidal infiltration (ISI) is a pattern of invasion that is rarely found on bone marrow (BM) biopsies, and is considered as a hallmark of splenic marginal zone cell lymphoma (SMZL). We analysed BM biopsies showing intrasinusoidal infiltration from 54 consecutive patients with different types of lymphoma to verify if ISI quantity was a diagnostic criterion for SMZL. There were 35 primary splenic lymphoma (PSL) and 19 non-PSL; 28 SMZL, three non-splenic MZL, six mantle cell, six small lymphocytic, four follicular, four diffuse large B cell, one peripheral T cell, one lymphoplasmacytic and one anaplastic large-cell lymphoma.

Prognostic relevance of CD105+ microvessel density in HNSCC patient outcome.

Angiogenesis is essential for the development and progression of malignant tumours, and there is increasing evidence that microvessel density (MVD) can be considered an indirect marker of neo-angiogenesis. However, there is still disagreement concerning the clinical relevance and prognostic significance of MVD in head and neck squamous cell carcinomas (HNSCCs). MVD was evaluated in 127 HNSCC patients by means of immunohistochemistry using monoclonal antibodies (mAbs) against CD34 and CD105 (endoglin), which has recently been described as a potent marker of neo-vascularisation in various malignancies.
