First results of a European multi-center registry of patients with anorectal malformations.
2013
Background: The European consortium on anorectal malformations (ARM-NET) was established to improve the health care of patients and to identify genetic and environmental risk factors. The aim of the present study was to present the first results on clinical data of a large European cohort of ARM patients based on our registry. Methods: In 2010, the registry was established including patient characteristics and data on diagnosis, surgical therapy, and outcome regarding complications. Patients born between 2007 and 2012 were retrospectively added. A descriptive analysis of this cohort was performed. Results: Two hundred and three ARM patients were included. Syndromes or chromosomal abnormalit…

Frequent reduction or absence of detection of the JAK2-mutated clone in JAK2V617F-positive patients within the first years of hydroxyurea therapy
2008
Abstract Objective: To analyse the effect of hydroxyurea (HU) on the JAK2-V617F allelic ratio (%JAK2-V617F) of patients with Polycythaemia Vera (PV) and Essential Thrombocythaemia (ET). Methods: Thirty-six patients were examined sequentially prior to and after on-set of (HU) therapy (8 PV, 17 ET), or while remaining untreated (2 PV, 9 ET). For all patients, the %JAK2-V617F was determined in purified blood granulocytes using sensitive allele-specific, quantitative PCRs. In a second study, two distinct groups of patients were examined at a single time point at the time of diagnosis (99 PV, 178 ET) or while receiving HU (36 PV, 98 ET). Results: HU therapy (median duration: 15 months) reduced t…
Vaccuuming method as a successful strategy in the diagnosis of active infestation by Pediculus humanus capitis
2020
ABSTRACT Most human epidemiological and clinical studies use visual inspection of the hair and scalp to diagnose Pediculus humanus capitis , however this method has low sensitivity to diagnose active infestations (presence of nymphs and adult lice). Vacuuming the hair and scalp has been used as a diagnostic method, but there are no previous data comparing its effectiveness with visual inspection. The aim of this study was to determine the prevalence of overall infestation (nits and trophic stages), of active infestation by Pediculus humanus capitis , and to evaluate the effectiveness of vacuuming in comparison with the visual inspection. Visual inspection was performed by three examiners an…
Ethnobotanical survey and cytotoxicity testing of plants of South-western Nigeria used to treat cancer, with isolation of cytotoxic constituents from…
2010
Abstract Ethnopharmacological relevance There is only scant literature on the anticancer components of medicinal plants from Nigeria, yet traditional healers in the area under study claim to have been managing the disease in their patients with some success using the species studied. Aim of study To document plants commonly used to treat cancer in South-western Nigeria and to test the scientific basis of the claims using in vitro cytotoxicity tests. Methods Structured questionnaires were used to explore the ethnobotanical practices amongst the traditional healers. Methanol extracts of the most common species cited were screened for cytotoxicity using the sulforhodamine B (SRB) assay in both…
Concordance of assays designed for the quantification of JAK2V617F: a multicenter study
2008
Background Many different techniques have been designed for the quantification of JAK2 V617F allelic burden, sometimes producing discrepant results. Design and Methods JAK2 V617F quantification techniques were compared among 16 centers using 11 assays based on quantitative polymerase chain reaction (with mutation-specific primers or probes, or fluorescent resonance energy transfer/melting curve analysis), allele-specific polymerase chain reaction, conventional sequencing or pyrosequencing. Results A first series of blinded samples (granulocyte DNA, n=29) was analyzed. Seven assays (12 centers) reported values inside the mean±2SD; the mean coefficient of variation was 31%. Sequencing techniq…

Immunoproteasome LMP2 60HH Variant Alters MBP Epitope Generation and Reduces the Risk to Develop Multiple Sclerosis in Italian Female Population
2010
BackgroundAlbeit several studies pointed out the pivotal role that CD4+T cells have in Multiple Sclerosis, the CD8+ T cells involvement in the pathology is still in its early phases of investigation. Proteasome degradation is the key step in the production of MHC class I-restricted epitopes and therefore its activity could be an important element in the activation and regulation of autoreactive CD8+ T cells in Multiple Sclerosis.Methodology/principal findingsImmunoproteasomes and PA28-alphabeta regulator are present in MS affected brain area and accumulated in plaques. They are expressed in cell types supposed to be involved in MS development such as neurons, endothelial cells, oligodendroc…
Immunogenicity of reduced antigen content tetanus–diphtheria–acellular pertussis vaccine in adolescents as a sixth consecutive dose of acellular pert…
2006
Three hundred and nineteen adolescents aged 10-12 years who had been previously vaccinated with five doses of acellular pertussis-containing vaccines received single doses of Tdap (reduced-antigen-content tetanus, diphtheria, acellular pertussis) and hepatitis A vaccines in a double-blind crossover trial. Long-term antibody persistence following vaccination with Tdap at pre-school age was similar to that following vaccination with DTaP (diphtheria-tetanus-acellular pertussis). After the sixth dose booster, Tdap induced a vigorous immune response, consistent with protection against diphtheria, tetanus and pertussis diseases.
Angiogenesis in oral lichen planus: an in vivo and immunohistological evaluation.
2010
Oral lichen planus (OLP) is an autoimmune disease with an inflammatory pathogenesis. The angiogenetic phenomenon is a mechanism at the base of the pathogenesis of chronic inflammatory processes. The aim of this research is to evaluate the angiogenetic phenomenon, comparing an in vitro method with an in vivo one. Thirty OLP patients and 30 healthy subjects were enrolled in the study. Immunohistochemical analysis of the vascular-endothelial growth factor (VEGF) and vascular-endothelial adhesion molecules were carried out by the means of primary antibodies and anti-CD34, anti-VEGF, anti-CD106 antigen (VCAM-1) and anti-CD54 antigen (ICAM-1). Capillary density and others capillaroscopic paramete…
