The development of solid-phase assays for antibody detection has aided in the frequent detection of human leukocyte antigen (HLA) antibodies in nonalloimmunized males. Some scientists have reported that these HLA antibodies are produced to pathogens or allergens and the reactivity with HLA coated beads is the result of cross-reactive epitopes. These(More)
PURPOSE The WHO diagnostic criteria underscore the role of bone marrow (BM) morphology in distinguishing essential thrombocythemia (ET) from early/prefibrotic primary myelofibrosis (PMF). This study examined the clinical relevance of such a distinction. METHODS Representatives from seven international centers of excellence for myeloproliferative neoplasms(More)
Diagnosis of essential thrombocythemia (ET) has been updated in the last World Health Organization (WHO) classification. We developed a prognostic model to predict survival at diagnosis, named IPSET (International Prognostic Score for ET), studying patients with WHO-defined ET. Age 60 years or older, leukocyte count ≥ 11 × 10(9)/L, and prior thrombosis(More)
BACKGROUND AIMS Mesenchymal stromal cells (MSC) have recently been identified as a therapeutic option in several clinical conditions. Whereas bone marrow (BM) is considered the main source of MSC (BM-MSC), the invasive technique required for collection and the decline in allogeneic donations call for alternative sources. Human umbilical cord (UC) represents(More)
We examined the prevalence and prognostic relevance of bone marrow reticulin fibrosis in 526 patients with World Health Organization-defined polycythemia vera evaluated at the time of initial diagnosis. Seventy-four patients (14%) displayed mostly grade 1 reticulin fibrosis, with only 2 cases showing higher-grade fibrosis. Presenting clinical and laboratory(More)
Helicobacter pylori colonization and the incidence, severity, activity and topography of gastritis were investigated systematically in antrum and corpus mucosal biopsies of 1177 subjects undergoing endoscopy in the absence of gastric complaints (asymptomatic, 49) or for non-ulcer dyspepsia (NUD; 631 patients, 72 of whom had gastric and/or duodenal(More)
Lymphocytic gastritis is characterized by lymphocytic infiltration of the surface and pit epithelium. Its cause has not been established, but an association with Helicobacter pylori infection or celiac disease has been suggested. We evaluated the histologic features of both gastric and duodenal biopsy specimens from 245 consecutive children and adolescents,(More)
AIMS Although it accounts for fewer than 0.2% of all head and neck tumours, temporal bone squamous cell carcinoma (SCC) is an aggressive malignancy with a poor prognosis in advanced cases. Novel therapeutic strategies should be developed focusing on specific targeted therapies. Maspin is a serpin showing tumour-suppressing activity which has therapeutic(More)
The spectrum of endocrine cell changes occurring in 80 cases of body-fundus chronic atrophic gastritis (CAG), mostly type A or multifocal, including various types of hyperplasia, precarcinoid lesions (20 cases), and neoplasia (carcinoid, 24 cases) have been analyzed histologically, histochemically, and ultrastructurally. Changes associated with gland(More)
Nerve sheath myxoma (NSM) of the oral mucosa is a slow-growing, benign, often asymptomatic submucosal mass. We report on a case of classical NSM of the tongue, with diagnostic and therapeutic approach to the case. Many NSM arise within the endoneurium of a peripheral nerve. It is a rare condition with no apparent differences between sexes in its prevalence.(More)
