Polycythemia vera (PV) is characterized by the presence of the JAK2V617F mutation in virtually all patients. Several studies have shown that the JAK2V617F mutational load decreases during treatment with alpha-interferon 2. We report on molecular and histomorphological bone marrow responses in seven PV patients with profound molecular responses during and ...

PCR-based clonality testing can be performed in all lymphoproliferations by analysing gene rearrangements of antigen receptors, rearrangements that are unique for each kind of lymphocyte. Reactive lymphoproliferations have polyclonally rearranged Ig/TCR genes, whereas malignant proliferations (leukaemias and lymphomas) show clonal rearrangements. The aim of this study was to assess the ...

The immunophenotypic profile of hematological malignancies is usually consistent among different sites of involvement; this consistency allows reliable diagnosis from peripheral blood, bone marrow, or lymph node, especially in cases of acute leukemia. Although in a minority of lymphoma patients, two or more different populations with discordant immunophenotypes have been ...

Gaucher disease (GD) is a lysosomal storage disorder characterized by anemia and thrombocytopenia, hepatosplenomegaly, and skeletal involvement. The management of Gaucher disease was improved by the development of enzyme replacement therapy (ERT). However, the bone response to ERT is generally slower compared to other clinical manifestations. Some have recommended the ...

Multi-drug resistance (MDR) is a major challenge in the treatment of multiple myeloma (MM). There is low sensitivity of technetium-99m methoxy isobutyl isonitrile ((99m)Tc-MIBI) whole body scan (WBS) in the detection of active MM lesions, because (99m)Tc-MIBI is washed out from malignant cells in the presence of P-glycoprotein (PGP). The ...

The determination of telomere length is useful for the characterization of dyskeratosis congenita (DC) and of aplastic anemias (AA) as well as hematological malignancies. Short telomeres result from a specific defect of telomere maintenance in DC and likely from higher cellular turnover in AA and hematological malignancies. Data are not ...

BACKGROUND: Turner syndrome (TS) is a congenital chromosomal abnormality, resulting in short stature, short fourth metacarpal, and retarded skeletal maturation in children. The existing methods of diagnosis, which include carpal angle, metacarpal sign, and body mass index (BMI), cannot accurately diagnose TS. The authors propose a novel procedure for examining ...

Much of the work aimed at elucidating the pathogenesis of osteonecrosis (ON) of the femoral head has focused on bone blood supply, with little attention to the surrounding synovial tissue (ST). We hypothesized that patients with ON exhibit synovial inflammation. Using immunohistological techniques, we found that a large population of ...

Infiltration anaesthesia with articaine, a local anaesthetic able to penetrate bone, may relieve procedural pain better than lidocaine in bone marrow aspiration and biopsy. This randomised, double-blind study comprised 150 patients with suspected or known haematologic disease. Either articaine 20mg/ml (50 patients), articaine 40mg/ml (49 patients) or lidocaine 20mg/ml (51 ...

Although it is known that neurofibromatosis 1 (NF1) patients suffer from vitamin D deficiency and display decreased bone mineral density (BMD), a systematic clinical and histomorphometrical analysis is absent. Our data demonstrate that NF1 patients display high bone turnover and accumulation of osteoid and that supplementation of vitamin D has ...

INTRODUCTION: There are very few data about relations between leptin and bone mineral density (BMD) in regular haemodialysed patients. We aimed to examine the relationship of serum leptin levels with BMD values in dialysed patients. We also assessed whether leptin is a significant predictor of BMD in haemodialysed patients. MATERIALS ...

Osteonecrosis (ON) is commonly caused by high doses of glucocorticoids or ethanol intake. We previously reported suppression of BMP-2 by dexamethasone was more pronounced and enhancement by lovastatin was less pronounced in bone marrow stromal cells (BMSCs) from patients with ON than from patients without ON. We therefore presumed the ...

We did a cross-sectional analysis of chronic pulmonary obstructive disease (COPD) patients without chronic use of systemic glucocorticoids (CUG). Osteoporosis was found in 51% and bone mineral density (BMD) was correlated with severity of disease. Low levels of vitamin D were found in 94%. All COPD patients may benefit from ...

Osteoporosis represents an important cause of morbidity in thalassaemia major patients; the etiopathogenesis is multifactorial and includes expansion of the bone marrow, endocrine disorders, iron overload and genetic factors. Two cytokines, osteoprotegerin (OPG) and receptor activator of nuclear factor kappa B ligand (RANKL), have recently been identified as important mediators ...

Chronic rhinosinusitis (CRS) is basically an inflammatory disease of the mucosa and periosteum of the sinuses. The possibility of local osteitis can cause persistent mucosal inflammation and lead to failure of treatment. Bone scintigraphy is the gold standard procedure for detecting the bone involvement. This study was designed to evaluate ...

Patients with bone metastases and elevated urinary N-telopeptide (uNTx), representing excessive bone resorption, are at increased risk for skeletal-related events (SREs), cancer progression, and death. Osteoclast-mediated bone resorption is regulated by RANKL. We evaluated the effect of denosumab, a fully human monoclonal antibody against RANKL, in patients with bone metastases ...

Cytopenia is a common problem in hematology outpatient clinics and among hospitalized patients. A bone marrow (BM) aspirate and biopsy are often performed to rule out an infiltrative versus intrinsic BM process, such as myelodysplastic syndrome (MDS). We have previously described a flow cytometric (FCM) assay useful in diagnosing MDS ...
