2010

Abstract After publication of the updated World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues in 2008, the Pathology Working Group of the International Lymphoma Epidemiology Consortium (InterLymph) now presents an update of the hierarchical classification of lymphoid neoplasms for epidemiologic research based on the 2001 WHO classification, which we published in 2007. The updated hierarchical classification incorporates all of the major and provisional entities in the 2008 WHO classification, including newly defined entities based on age, site, certain infections, and molecular characteristics, as well as borderline categories, early and “in situ” …

Oral Findings in Postmenopausal Women Attending Dental Hospital in Western Part of India

2012

Objectives: To know the nature, incidence and severity of oral manifestations occurring in postmenopausal women. Study design: Oral changes were observed in 365 postmenopausal women and 365 age matched male individuals attending the department of Oral Medicine and Radiology. The patients were asked about complaints of dry mouth, taste and breath changes, mucosal and facial pain and were examined for oral changes such as ulceration, white and red lesions. The results obtained from the study were then correlated with various other similar studies. Results: The important oral findings in postmenopausal women were mucosal burning/pain (25.8%), dry mouth (27.1%), altered taste (3.6%), altered br…

Gene Rearrangements and Other Molecular Features in Aggressive B-Cell Lymphomas of Patients with and without HIV-Infection

2015

Abstract Aggressive B-cell Lymphomas are the second most frequent AIDS-defining cancers. Few studies have compared the molecular characteristics of aggressive B-cell lymphomas in patients with and without HIV-infection; and to our knowledge, there are no reports comparing the incidence of gene rearrangements between the two groups and their impact on outcome in series treated with RCHOP. We retrospectively studied two series of patients with (N=32) and without HIV-infection (N=43) with diffuse large B-cell lymphomas (DLBCL) NOS (75% and 70%, respectively), T-rich DLCBL (13% and 5%), transformed DLBCL (3% and 14%) and double-hit (DH) DLCBL (9% and 11%) [defined by translocations affecting MY…

Risk Factors, Lifestyle and Prevention among Adolescents with Idiopathic Juvenile Scoliosis: A Cross Sectional Study in Eleven First-Grade Secondary …

2021

Adolescent idiopathic scoliosis (AIS) has an incidence of 2–3% in the general population and a multifactorial etiology. The present study aims to analyze modifiable risk factors and their interactions in the development of AIS in order to increase knowledge about the disease and to prevent the evolution of AIS in young students with tailored public health strategies. A cross-sectional study was conducted over two consecutive school years among students attending 11 first-grade secondary schools in the province of Palermo, Italy. A self-administered questionnaire that investigated socio-demographical, physical and anamnestic characteristics and habits, focusing on possible risk factors…

2021

ObjectivePatients with sickle cell disease (SCD) are prone to multiple episodes resulting in frequent hospital visits. We determined the time trends, sociodemographic and health factors associated with length of stay (LoS) for patients with SCD in Ghana.Design, participants, settingWe retrospectively analysed SCD hospitalisation records of 22 680 patients from a nationwide database of the Ghana Health Service from 2012 to 2017.Outcome measuresFactors associated with LoS were estimated using Cox regression, while the cumulative incidence of being discharged alive was estimated with in-hospital death as a competing risk.ResultsPatients admitted for SCD over 6 years constituted 22 680 (0.8%) o…

Epidemiology of pneumococcal disease in children in Germany

2001

UNLABELLED Recently published and as yet unpublished data allow a reasonable estimate of the annual burden of pneumococcal disease in Germany. At least 277,000 episodes of otitis media and at least 2,000 episodes of sinusitis occur in children under the age of 5 y. Pneumococcal meningitis was found in 200 children under the age of 16 y; the estimate for all age groups ranges from 450 to 1100 cases. Of approximately 150,000 cases of ambulatory pneumococcal pneumonia, at least 63,000-105,000 patients are hospitalized each year. CONCLUSION Further studies of pneumococcal epidemiology in Germany are needed, and continued surveillance will be necessary for a better understanding of the overall b…

Seroepidemiology of pertussis infection in an urban childhood population in Cameroon.

1991

In 1989, the prevalence of IgG antibodies to pertussis toxin (PT) in a sample of 367 unvaccinated apparently healthy children 5-14 years old was estimated by ELISA in Kumba City (Cameroon). Children were recruited using a systematic random sampling from six primary schools located in different districts of the city. The sample was representative of the various socioeconomic classes. The overall prevalence was 75%; it increased from 62% in 5 year old children to 81% in children 12-14 years old (P less than 0.01). IgG antibody prevalence was positively related to the family size. Children belonging to households of nine or more members had a 2.2-fold risk (C.I. 95 per cent = 1.1-4.6) of previ…

Systematic review of the association between particulate matter exposure and autism spectrum disorders

2017

Particulate matter (PM) as an environmental pollutant is suspected to be associated with autism spectrum disorders. The aim of the present study was to review the epidemiological literature currently available on the relation between PM exposure and diagnosis of ASD. The PubMed database was searched from November 2015 up to January 2016 by one of the authors. We included observational studies (cohort and case control studies) published in English carried out in children within the last 10 years, measuring PM exposure and health outcomes related to ASD. 13 studies met the inclusion criteria. Four of the studies found no association between PM exposure and ASD. The other 8 studies show positi…

OC-87 Gaucher disease in romania – baseline characteristics, specific diagnosis. treatment and outcome

2017

Gaucher disease is a autosomal recessive inherited monogenic disease caused by beta-glucocerebrosidase deficiency. Clinically, there are three types: type 1 (non-neuronopathic), type 2 (acute neuronopathic) and type 3 (chronic neuronopathic), in 92%, 1% and respectively 7% of patients. Specific diagnosis has been possible in Romania since 1997 and enzyme replacement therapy since 2002. The aim of the study is to present the epidemiologic, clinical and molecular data of the Romanian patients with Gaucher disease ant their evolution. Patients and methods Seventy-nine patients (76 patients with Gaucher disease type 1 and 3 patients with Gaucher disease type 3; F/M=1.37/1) were evaluated clinic…

The changing scenario of hepatocellular carcinoma in Italy: an update

2021

Background and aims: Epidemiology of hepatocellular carcinoma (HCC) is changing in most areas of the world. This study aimed at updating the changing scenario of aetiology, clinical presentation, management and prognosis of HCC in Italy during the last 15 years. Methods: Retrospective analysis of the Italian Liver Cancer (ITA.LI.CA) database included 6034 HCC patients managed in 23 centres from 2004 to 2018. Patients were divided into three groups according to the date of cancer diagnosis (2004-2008, 2009-2013 and 2014-2018). Results: The main results were: (i) a progressive patient ageing; (ii) a progressive increase of non-viral cases and, particularly, of ‘metabolic’ and ‘metabolic + alc…
