Detailed clinical, genetic and neuroimaging characterization of OFD VI syndrome.
2012
Oral-facial-digital syndrome type VI (OFD VI) is characterized by the association of malformations of the face, oral cavity and extremities, distinguished from the 12 other OFD syndromes by cerebellar and metacarpal abnormalities. Cerebellar malformations in OFD VI have been described as a molar tooth sign (MTS), thus, including OFD VI among the "Joubert syndrome related disorders" (JSRD). OFD VI diagnostic criteria have recently been suggested: MTS and one or more of the following: 1) tongue hamartoma(s) and/or additional frenula and/or upper lip notch; 2) mesoaxial polydactyly of hands or feet; 3) hypothalamic hamartoma. In order to further delineate this rare entity, we present the neuro…
A preliminary clinical trial using flowable glass-ionomer cement as a liner in proximal-ART restorations: the operator effect
2013
Objectives: This in vivo study was carried out to assess the influence of the operator experience on the survival rate of proximal-ART restorations using a two-layer technique to insert the glass-ionomer cement (GIC). Study Design: Forty five proximal cavities in primary molars were restored in a school setting according to the ART technique. The cavities were restored by two operators with Ketac Molar Easymix, and received a flowable layer of GIC prior to a second GIC layer with a regular consistency. The operators had different clinical experiences with ART (no experience or two years of experience), but both completed a one-week training to perform the restorations and the GIC mixing in …
Treatment of prepubertal periodontitis. A case report and discussion.
1992
Abstract This paper reports the treatment of prepubertal periodontitis in a 3–year-old girl with Papillon-Lefevre Syndrome. Initially, the patient was found to have a myeloperoxidase deficiency and microbiological tests have identified Bacteroides and Fusobacterium, in 60% and 25%, respectively of the total number of microbial flora cultivated. The initial treatment was extraction of all the primary teeth with grade 3 mobility, scaling, root planing and daily subgingival irrigation with a 0.2% solution of chlorhexidine. Several months before the eruption of the first permanent molars, the rest of the primary teeth were extracted. The patient was treated with daily subgingival irrigation of …
Diversity of human rotaviruses detected in Sicily, Italy, over a 5-years period (2001-2005).
2007
It is well known that the death of dopaminergic neurons of the substantia nigra pars compacta (SNc) is the pathological hallmark of Parkinson's disease (PD), the second most common and disabling condition in the expanding elderly population. Nevertheless, the intracellular cascade of events leading to dopamine cell death is still unknown and, consequently, treatment is largely symptomatic rather than preventive. Moreover, the mechanisms whereby nigral dopaminergic neurons may degenerate still remain controversial. Hitherto, several data have shown that the earlier cellular disturbances occurring in dopaminergic neurons include oxidative stress, excitotoxicity, inflammation, mitochondrial dy…
Molecular spreading and predictive value of preclinical IgE response to Phleum pratense in children with hay fever.
2012
Background IgE sensitization against grass pollen is a cause of seasonal allergic rhinitis. Objective We sought to investigate the evolution at the molecular level and the preclinical predictive value of IgE responses against grass pollen. Methods The German Multicentre Allergy Study examined a birth cohort born in 1990. A questionnaire was administered yearly, and blood samples were collected at 1, 2, 3, 5, 6, 7, 10, and 13 years of age. Grass pollen–related seasonal allergic rhinitis (SARg) was diagnosed according to nasal symptoms in June/July. Serum IgE antibodies to Phleum pratense extract and 8 P pratense molecules were tested with immune-enzymatic singleplex and multiplex assays, res…
Why Asian children outperform students from other countries? Linguistic and parental influences comparing Chinese and Italian children in preschool e…
2016
This paper focusing on the complex situation of the Italian multiculturalism and trying to reply to why Asian children mathematically outperform students from other countries, discusses from the epistemological point of view, Chinese children’s skills before to start their formal education in Italian educational school context. A review of the literature, comparing pre-schoolers competences of Asian and Western students, reveals two important influenced factors: linguistic and parental stimuli. In particular many researchers showed that the structure of the Chinese language provides in children a head start in basic math skills, for example to discover, since preschool activities, a pre-alg…
Informal musical activities are linked to auditory discrimination and attention in 2-3-year-old children: an event-related potential study
2012
The relation between informal musical activities at home and electrophysiological indices of neural auditory change detection was investigated in 2-3-year-old children. Auditory event-related potentials were recorded in a multi-feature paradigm that included frequency, duration, intensity, direction, gap deviants and attention-catching novel sounds. Correlations were calculated between these responses and the amount of musical activity at home (i.e. musical play by the child and parental singing) reported by the parents. A higher overall amount of informal musical activity was associated with larger P3as elicited by the gap and duration deviants, and smaller late discriminative negativity r…
Road Traffic Pollution and Childhood Leukemia: A Nationwide Case-control Study in Italy
2016
Background The association of childhood leukemia with traffic pollution was considered in a number of studies from 1989 onwards, with results not entirely consistent and little information regarding subtypes. Aim of the study We used the data of the Italian SETIL case-control on childhood leukemia to explore the risk by leukemia subtypes associated to exposure to vehicular traffic. Methods We included in the analyses 648 cases of childhood leukemia (565 Acute lymphoblastic–ALL and 80 Acute non lymphoblastic-AnLL) and 980 controls. Information on traffic exposure was collected from questionnaire interviews and from the geocoding of house addresses, for all periods of life of the children. Re…
Insights on Kawasaki disease and multisystem inflammatory syndrome: relationship with COVID-19 infection.
2021
At the beginning of coronavirus disease 2019 (COVID-19) children seemed to be less affected and with milder symptoms than adults. Afterward, however, a warning was released regarding the possible association between COVID-19 and Kawasaki disease (KD) or Kawasaki-like disease. Thereafter, labels of Paediatric Inflammatory Multisystem Syndrome Temporally associated with SARS-CoV-2 (PIMS-TS) in Europe and Multisystem Inflammatory Syndrome in Children (MIS-C) in the USA were coined to refer to this new disease entity. The reality is that PIMS-TS/MIS-C resembles certain KD complications such as toxic shock syndrome and macrophage activation syndrome than to classic KD. PIMS-TS/MIS-C and KD share…
Persistence of Human Bocavirus 1 in Tonsillar Germinal Centers and Antibody-Dependent Enhancement of Infection
2021
Human bocavirus 1 (HBoV1), a common pediatric respiratory pathogen, can persist in airway secretions for months hampering diagnosis. It also persists in tonsils, providing potential reservoirs for airway shedding, with the exact location, host cell types, and virus activity unknown.
