ABSTRACT

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. Migraine was diagnosed according to the international criteria. RESULTS: A total of 3914 patients underwent a breath test and 2200 an esophagogastroduodenoscopy at two hospitals, in Piedmont (Italy), in a 5-year period; a total of 1362 questionnaires were included in the study. The mean age of the subjects was 53 years; there were 777 women (57%). HP was detected in 364 (27%) subjects. A total of 702 (51%) subjects suffered from headache: migraine with aura was diagnosed in 176 subjects (176/702, i.e., 25% of the headache group; 176/1362, i.e., 13% of the total population); migraine without aura in 98 subjects (98/702, i.e., 14% of the headache group; 98/1362, i.e., 7% of the total). The logistic regression model did not detect any significant association between HP infection and headache, while a significant association between HP and headache frequency (p =0.009) was found, independently of age, gender, comorbidity, and diagnostic category. CONCLUSION: Our study does not reveal an association between chronic HP infection and migraine. However, since HP is significantly associated with higher headache frequency, a role for HP as a risk factor for headache chronification, possibly underlain by inflammatory mechanisms, may be supposed.

ABSTRACT

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. RESULTS: Our approach was successful, sparing our already frail patient further surgical procedures. Six months pyelography confirmed the complete ureteral blockage with absence of extravasation. CONCLUSIONS: In complicated scenarios with urinary leakages and frail patients, synthetic glues such as Ifabond might represent an interesting therapeutic option to solve the fistulas, leading to durable success with a minimally invasive approach.

ABSTRACT

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. The quantity of BM infiltrate was assessed on CD45, CD20 and CD3 stained sections. The mean percentage of total (TI) and intrasinusoidal (ISI) lymphocytes was calculated in 10 areas for each case. TI quantity was 21.57 in PSL and 35.05 in non-PSL (P = 0.04). ISI quantity was 5.23 in PSL and 7.62 in non-PSL (P = 0.08), 5.83 in SMZL and 2.83 in other types of PSL (P = 0.12), 4.46 in non-splenic MZL and 8.21 in other types of non-PSL (P = 0.28). No difference in ISI quantity was found among the lymphoma subtypes, either in PSL (P = 0.74) or non-PSL (P = 0.3). The data demonstrate that ISI quantity in BM biopsies is not a reliable diagnostic parameter for SMZL.

ABSTRACT

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. MVD was expressed as the mean number of vessels/mm2. The mean CD34+ and CD105+ MVD values were significantly higher in T3-T4 tumours and those in an advanced clinical stage; furthermore, CD105+ MVD was significantly higher in N+ tumours. The patients with a high CD105+ MVD had a significantly shorter disease-free and overall survival; CD34+ MVD was not associated with survival. Similarly, in the subset of lymph-node negative patients, higher CD105+ MVD values were significantly associated with either OS and DFS. Multivariate analysis showed that a high CD105+ MVD was the only independent marker of tumour recurrence or death. Our data suggest that CD105+ MVD may represent an additional prognostic factor in HNSCC patients providing more accurate data for the determination of prognosis and management in the subset of lymph node negative patients.
