Ramadan Exposure In Utero and Child Mortality in Burkina Faso: Analysis of a Population-Based Cohort Including 41,025 Children.
2017
Ramadan exposure in utero can be regarded as a natural experiment with which to study how nutritional conditions in utero influence susceptibility to disease later in life. We analyzed data from rural Burkina Faso on 41,025 children born between 1993 and 2012, of whom 25,093 were born to Muslim mothers. Ramadan exposure was assigned on the basis of overlap between Ramadan dates and gestation, creating 7 exclusive categories. We used proportional hazards regression with difference-in-differences analysis to estimate the association between Ramadan exposure at different gestational ages and mortality among children under 5 years of age. Under-5 mortality was 32 deaths per 1,000 child-years. U…
A retrospective analysis of oral and maxillofacial pathology in a pediatric population from Rio de Janeiro?Brazil over a 75-year period
2018
Background The aim of this study was to analyze the distribution of oral and maxillofacial lesions affecting children and adolescents patients from a single oral pathology laboratory from Rio de Janeiro, Brazil. Material and Methods Oral and maxillofacial lesions biopsied in patients younger than 19-years were retrieved from the oral pathology files of the Department of Oral Diagnosis and Pathology, School of Dentistry, Federal University of Rio de Janeiro over a 75-year period (1942-2017). The clinical data and the diagnoses of each case were included in a Microsoft Excel® database, being classified into 13 categories according to the etiology. A descriptive analysis of the variables age, …
Serotypes, Antibiotic Resistance, and Class 1 Integrons in Salmonella Isolates from Pediatric Cases of Enteritis in Tehran, Iran
2011
The present study was conducted to investigate serotype distribution, antimicrobial resistance patterns, carriage of class 1 integron, and clonality of Salmonella strains isolated from patients aged 0-12 years in Tehran, Iran, during 2007-2008. A total of 139 Salmonella isolates were studied. Salmonella serotypes Enteritidis, Infantis, and Typhimurium included 84.9% of isolates, Enteritidis accounting for 41.7%. The most prevalent resistances were to doxycycline (64.7%), nalidixic acid (61.2%), tetracycline (51.8%), and streptomycin (42.8%). Fifty-three (38.1%) isolates contained class 1 integron. Eight different gene cassettes were identified, aadA1 being the most frequently encountered. P…
Analisi delle evidenze epidemiologiche sui fattori di rischio indoor per malattie respiratorie e allergiche nelle strutture scolastiche [Analysis of …
2012
Il diritto a respirare aria sana nelle scuole è stato sancito già nell’anno 2001 in un documento dell’European Federation of Asthma and Allergy Associations che ha evidenziato scarsa attenzione e assenza di direttive specifiche dell’Unione Europea relativamente agli effetti sulla salute da inquinamento dell’aria nelle scuole, ed è sostenuto dal numero enorme di bambini e ragazzi che frequentano le aule scolastiche. Negli ultimi anni, a livello europeo si è sviluppato un sempre crescente interesse nei confronti dell’effetto della qualità dell’aria dell’indoor scolastico (IAQ) sulla salute dei ragazzi, e sono stati avviati numerosi progetti di ricerca internazionali mirati, appunto, a determi…
Validation of the swimming competence questionnaire for children.
2020
Two studies were employed to test the reliability and validity of the Swimming Competence Questionnaire (SCQ) among primary school children. Study 1 was a cross-sectional survey in 4959 primary school children. Study 2 was a pre-post-test quasi-experiment among 1609 primary school children who underwent a 20-lesson learn-to-swim programme. In Study 1, exploratory structural equation modelling revealed excellent goodness-of-fit and scale reliability for a two-factor model comprising distance and skill factors, which supported the construct and convergent validity. SCQ scores were significantly and positively correlated with swimming outcomes (i.e., self-efficacy, intention, swimming frequenc…
PLAYING WITH THE COLORS-PRE-SCHOOL CHILDREN’S SELF-DIRECTED DRAWING EXPERIANCE
2019
At the pre-scool age, playing is the main key to the child’s way to express them selfs in drawing process. In order to ensure the self-directed drawing, there is a need for the availability of diverse naterials throughout of the day, enabling the child to act and play in accordance with his intentions. In a drawing process, trying out different techniques, tools,mixing colors, trying to discover new ways of expression, observing and imitating other (children’s or adult) actions, provides the basic conditions for meaningful activity of a child. The aim of the thesis is to find out theoretically and practically the essence of self-directed drawing activity of preschool children and possibilit…

Electropherotypes, subgroups and serotypes of human rotavirus strains causing gastroenteritis in infants and young children in Palermo, Italy, from 1…
1990
During 1985-89, an epidemiological survey was conducted in Palermo, Sicily (Southern Italy) on group A human rotavirus (HRV) strains which cause gastroenteritis in infants and young children. Two hundred and thirty eight HRV strains were characterized for subgroup and serotype using monoclonal-antibody-based ELISA systems, and for electropherotype using polyacrylamide gel electrophoresis. Subgroup II strains were largely predominant, constituting 218/238 of the positive stool samples (91.6%). Among the serotypes, 192/238 strains (80.7%) were serotype 1 and 16 strains (6.7%) were serotype 4; serotype 2 circulated intermittently and serotype 3 was nearly absent (only one subgroup I strain was…
G2 rotavirus infections in an infantile population of the South of Italy: variability of viral strains over time.
2005
Rotavirus positive samples collected in Palermo, Italy, during 2002–2004 did not react with the G2 type-specific RV5:3 monoclonal antibodies (MAbs) and could be identified as G2 only by RT-PCR genotyping. The genetic variation of VP7 and VP4 antigenic proteins was studied in 14 G2 samples including a selection of both those successfully characterized by serotyping and those failing to be serotyped. The phylogenetic analysis performed on partial VP7 sequences showed a temporal clustering of these strains, with those isolated in Palermo in 2003 belonging to the same lineage of G2 MAbs-unreactive strains identified in UK in 1996–1997 and in Bari, Italy, in 2003–2004. A single amino acid substi…
Characterization of the first extended-spectrum beta-lactamase-producing nontyphoidal Salmonella strains isolated in Tehran, Iran.
2009
The infections caused by Salmonella remain a significant public health problem throughout the world. beta-Lactams and fluoroquinolones are generally used to treat invasive Salmonella infections, but emergence and spread of antibiotic-resistant strains are being increasingly notified in many countries. In particular, detection of extended-spectrum beta-lactamases (ESBLs) in Salmonella spp. is a newly emerging threat worldwide. This study was carried out to characterize beta-lactamase-producing Salmonella strains identified in Tehran, Iran. Over the 2-year period from 2007 to 2008, 6 of 136 Salmonella isolates recovered from pediatrics patients, including three Salmonella enterica serotypes E…
