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...

BACKGROUND: Pressurized metered-dose inhalers (pMDIs) should be shaken before use to prevent creaming or sedimentation of the drugs in solution; however, data published on this topic are limited, and it is rarely specified how soon after shaking the device should be actuated. Delays between shaking and firing the pMDI have previously been shown to cause significant inhomogeneity in delivered dose. We studied the effect of various shake-fire delays on the drug delivered from five commercially available pMDIs commonly prescribed for asthma and chronic obstructive pulmonary disease to assess the potential variability in delivered dose...

BACKGROUND: Inflammatory bowel disease [IBD] is considered to result from the interplay between host and intestinal microbiota but its pathogenesis is incompletely understood. While IBD in adults has shown to be associated with marked changes in body fluid metabolomics, there are only few studies in children. Hence, this prospective study addressed the faecal and serum metabolomics in newly diagnosed paediatric IBD. METHODS: Paediatric patients with IBD undergoing diagnostic endoscopies and controls also with endoscopy but no signs of inflammation provided blood and stool samples in a tertiary care hospital...
