This case-control study identified the association between the arsenic methylation capacity and developmental delays and explored the association of this capacity with the health status of children. We recruited 120 children with developmental delays and 120 age- and sex-matched children without developmental delays. The health status of the children was assessed using the Pediatric Quality of Life Inventory (PedsQL) and Pediatric Outcomes Data Collection Instrument (PODCI). The arsenic methylation capacity was determined by the percentages of inorganic arsenic (InAs%), monomethylarsonic acid (MMA(V)%), and dimethylarsinic acid (DMA(V)%) through liquid chromatography and hydride generation atomic absorption spectrometry...

PURPOSE: Children undergoing operative intervention while induced under general anesthesia are at risk for experiencing a significant decrease in core body temperature that can lead to adverse systemic effects. Given that the head contributes an estimated 18% of a child's body surface area, we theorized that a liquid-warming garment applied to the head could control a pediatric patient's core body temperature during surgical procedures. METHODS: Patients undergoing elective, non-cranial, general surgical procedures were enrolled in the study...

We have previously shown alterations in the composition of the gut microbiota in children with enthesitis-related arthritis (ERA). To explore the mechanisms by which an altered microbiota might predispose to arthritis, we performed metabolomic profiling of fecal samples of children with ERA. Fecal samples were collected from two cohorts of children with ERA and healthy control subjects. Nano-liquid chromatography-mass spectroscopy (LC-MS) was performed on the fecal water homogenates with identification based upon mass: charge ratios...

Accidents and burns are a major problem in Italy and in industrialized countries, due to the consequences they have on health, especially in children aged 0-4 years. In Italy, about 400 people die each year from burns, with over 70% of these occurring in the home. In the European Union, burns are one of the top five causes of death from accidents, accounting for 3% of all deaths from accidents and violence in those age groups. One percent of all deaths in children are due to burns. In this paper, we illustrate the results of qualitative analysis, conducted according to the methodology of content analysis, on narratives included in the anamnesis of clinical papers at the ED in 738 cases of burns in children (0-14 years) observed in a sample of Emergency Departments in the years 2005-2009...

BACKGROUND: Middle ear adenoma with neuroendocrine differentiation (MEA-ND), also known as carcinoid tumor of the middle ear, is an extremely rare neoplasm, especially when located within the tympanic cavity. To the best of our knowledge, this represents the first pediatric case of a MEA-ND described in Europe. Excluding the present case, only three other pediatric cases of this disease have been published globally. CASE REPORT: We report on a 15-year-old female patient who presented with conductive hearing loss of the right ear...

We investigated the knowledge level and risk factors for pediatric unintentional burns in rural Southwest China with an aim to provide basic evidence for the prevention strategies. A stratified sampling method was used to recruit 1842 rural children from 9 schools. Self-reported burns during the past 12 months and relevant risk factors were collected by questionnaires. The burn incidence of all surveyed children was 12.7% (95% confidence interval [95% CI] 11.2-14.2%). We found that burn incidence had a trend to increase with the increasing school grade level and a trend to decrease with increasing knowledge scores on burns...

BACKGROUND: Microsampling techniques have several advantages over traditional blood collection. Dried blood spot (DBS) sampling and blood collection with heparinized capillaries are the standard techniques. Volumetric absorptive microsampling (VAMS) is a novel technique that collects a fixed volume of blood by applying an absorbent tip to a blood drop. In the present study we explored the feasibility of HbA1c monitoring with VAMS sampling at home and analysis in the laboratory. METHODS: Diabetic patients were enrolled in this study during consultation with the endocrinologist...

Otitis media (OM) or middle ear inflammation is the most common pediatric disease and leads to significant morbidity. Although understanding of underlying disease mechanisms is hampered by complex pathophysiology it is clear that epithelial abnormalities underpin the disease. There is currently a lack of a well characterised in vitro model of the middle ear (ME) epithelium that replicates the complex cellular composition of the middle ear. Here we report the development of a novel in vitro model of mouse middle ear epithelial cells (mMECs) at air liquid interface (ALI) that recapitulates the characteristics of the native murine ME epithelium...
