The preventive care of medication-related osteonecrosis of the jaw (MRONJ): a position paper by Italian experts for dental hygienists
2022
Abstract Purpose The prevention and early diagnosis of medication-related osteonecrosis of the jaw (MRONJ) is fundamental to reducing the incidence and progression of MRONJ. Many in the field believe that dental hygienists should play an integral role in primary and secondary MRONJ prevention. However, to date, very few publications in the literature have proposed standardised MRONJ protocols, which are dedicated to dental hygienists. The aim of this study was to provide guidance to the health care providers managing MRONJ. Methods The expert opinion in this study was developed by dental hygienists from the main Italian technical-scientific associations (Italian Dental Hygienists Associatio…
Pertussis in adults with persistent cough: a prospective follow up study in primary care.
2009
Despite high coverage of pertussis vaccine, B. pertussis has remained endemic and adults are recognized as reservoir for infection among incompletely immunized infants. Between November 15th 2004 and November 14th 2006, 37 general practitioners, attending 56,658 adults, recruited all patients with persistent cough. A diagnosis of pertussis was considered in those with an unexplained cough, lasting 14 or more days and a positive polymerase chain reaction (PCR) or enzyme-linked immunosorbent assay (ELISA) IgG anti-Pertussis Toxin (PT). During the period of the study 86 patients presented with persistent cough (106 cases per 100,000 person-years). According to laboratory criteria, 35% were cla…
Efficacy of Acellular Pertussis Vaccine in Early Childhood After Household Exposure
1996
Objective. —To evaluate the efficacy of a three-dose primary vaccination with a diphtheria-tetanus tricomponent acellular pertussis vaccine against "typical" pertussis, defined as a spasmodic cough of 21 days or longer with confirmation of Bordetella pertussis infection by culture or serology. Design. —Passive monitoring for suspected first household (index) cases of typical pertussis in six areas in Germany comprising 22 505 children vaccinated with study vaccine at 3, 4, and 5 months of age. Blinded, prospective follow-up of household contacts of index cases for incidence and progression of pertussis. Setting. —Six areas in Germany with a high incidence of pertussis. Subjects. —Four hundr…
Spatial distribution of brucellosis in sheep and goats in Sicily from 2001 to 2005
2007
Spatial analysis is making an increasingly important contribution to surveillance measures due to its ability to enable immediate visualization of information on the phenomenon studied. The authors describe the spatial distribution of prevalence and incidence of brucellosis in small ruminants in Sicily between 2001 and 2005. the study was conducted by integrating geografic information system (GIS)tecnology (MapInfo Professional 7.0) with SaTscan software to the perform an epidemiological analysis of the municipalities and to locate problem areas. A comparison between the thematic maps produced for brucellosis in small ruminants on the basis of prevalence and incidence data for each individu…
Atmospheric dust, early cases, and localized meningitis epidemics in the African meningitis belt: an analysis using high spatial resolution data.
2018
8 pages; International audience; Background : Bacterial meningitis causes a high burden of disease in the African meningitis belt, with regular seasonal hyperendemicity and sporadic short, but intense, localized epidemics during the late dry season occurring at a small spatial scale [i.e., below the district level, in individual health centers (HCs)]. In addition, epidemic waves with larger geographic extent occur every 7–10 y. Although atmospheric dust load is thought to be an essential factor for hyperendemicity, its role for localized epidemics remains hypothetic.Objectives : Our goal was to evaluate the association of localized meningitis epidemics in HC catchment areas with the dust lo…
Cardiovascular disease burden: Italian and global perspectives
2021
Background Cardiovascular disease (CVD) is still the leading cause of death worldwide, responsible for an estimated 17.8 million deaths globally in 2017, accounting for 31.8% of all deaths. In this review, we aim to provide an updated overview of CVD burden from an Italian and a global perspective. Methods Crude and age-standardized incidence and prevalence, as well as age-standardized mortality rate and morbidity rate (expressed as disability-adjusted life years - DALYs), of different cardiovascular conditions, derived from the Global Burden of Disease Injuries, and Risk Factors Study (GBD) 2017, were reported and compared between Italy and the world. Results Crude prevalence of CVD in Ita…
TP53 mutations and hepatocellular carcinoma: insights into the etiology and pathogenesis of liver cancer.
2007
Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide and the major risk factors include chronic infections with the hepatitis B (HBV) or C (HCV) virus, and exposure to dietary aflatoxin B(1) (AFB(1)) or alcohol consumption. Multiple genetic and epigenetic changes are involved in the molecular pathogenesis of HCC, for example, somatic mutations in the p53 tumor suppressor gene (TP53) and the activation of the WNT signal transduction pathway. AFB(1) frequently induces G:C to T:A transversions at the third base in codon 249 of TP53 and cooperates with HBV in causing p53 mutations in HCC. The detection of TP53 mutant DNA in plasma is a biomarker of both AFB(1) exposur…
Germline Predisposition to Pediatric Cancer, from Next Generation Sequencing to Medical Care
2021
Knowledge about genetic predisposition to pediatric cancer is constantly expanding. The categorization and clinical management of the best-known syndromes has been refined over the years. Meanwhile, new genes for pediatric cancer susceptibility are discovered every year. Our current work shares the results of genetically studying the germline of 170 pediatric patients diagnosed with cancer. Patients were prospectively recruited and studied using a custom panel, OncoNano V2. The well-categorized predisposing syndromes incidence was 9.4%. Likely pathogenic variants for predisposition to the patient’s tumor were identified in an additional 5.9% of cases. Additionally, a high number of pathogen…
Statistical methods for spatial cluster detection in childhood cancer incidence : A simulation study
2021
BACKGROUND AND OBJECTIVE: The potential existence of spatial clusters in childhood cancer incidence is a debated topic. Identification of such clusters may help to better understand etiology and develop preventive strategies. We evaluated widely used statistical approaches to cluster detection in this context.; METHODS: Incidence of newly diagnosed childhood cancer (140/1,000,000 children under 15 years) and nephroblastoma (7/1,000,000) was simulated. Clusters of defined size (1-50) were randomly assembled on the district level in Germany. Each cluster was simulated with different relative risk levels (1-100). For each combination 2000 iterations were done. Simulated data was then analyzed …
Recurrences following treatment of proliferative verrucous leukoplakia: A systematic review and meta-analysis.
2021
Objective A systematic review and meta-analysis was made of the incidence of recurrences in patients with proliferative verrucous leukoplakia subjected to different types of treatment. Methods The study was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. A literature search was made in the Medline (PubMed), EMBASE and Web of Science databases, together with a manual search, covering the period from 1985 to January 2020, with no language restrictions. Studies were included if they described treatments applied to at least 10 patients with the corresponding outcomes. Methodological quality was evaluated using Jadad sca…
