Retropharyngeal abscess (RPA) in children is a serious deep neck space infection that rarely is complicated by extension into the mediastinum. RPA with mediastinal abscess requires prompt surgical management, generally via external or transoral approach. We present the case of a 3-year-old boy with RPA with mediastinal extension who was managed with a unique multidisciplinary surgical approach with otolaryngology and interventional radiology. A transoral approach was utilized to pass a transnasal drain with image guidance into the mediastinal fluid collection. This report reviews the presentation and surgical management of RPA with mediastinal extension and describes a unique minimally invasive approach to drainage.
  The Italian Guideline for the management of acute otitis media (AOM) in children has been recently updated. We conducted a cross-sectional survey to investigate the adherence of Italian primary care paediatricians to the guideline recommendations.
 
  A questionnaire including 13 closed-ended questions was administered to the paediatricians participating in the 24th National Congress of Practical Pediatrics, held in Florence in November 2019.  https://www.selleckchem.com/  The answers were collected and analyzed.
 
  Eight hundred fifty-four out of 1000 questionnaires were collected (85.4%). Most of the participants declared that they did not remove the cerumen (63.9%). Pneumatic otoscope and tympanometry were routinely used by a minority of paediatricians (9.6% and 3.9%, respectively); all the participants declared to routinely prescribe oral analgesic drugs and 97.6% of them considered amoxicillin or amoxicillin/clavulanic acid as the first-choice antibiotic. In an uncomplicated unilateral AOM case, the preferred strategy was immediate antt use of antibiotics in terms of optimal dosage, duration and number of daily administrations, and to implement proper AOM prevention strategies.
 Our data suggest adequate adherence of the guideline recommendations considering the preferred antibiotic drug, pain management and the choice between immediate antibiotic therapy and watchful waiting. Conversely, targeted training programs are needed to improve adherence to recommendations on cerumen removal, use of pneumatic otoscopy, correct use of antibiotics in terms of optimal dosage, duration and number of daily administrations, and to implement proper AOM prevention strategies.
  To evaluate the factors contributing to middle ear pathology, hearing and speech development among cleft palate children treated for middle ear effusion.
 
  A prospective cross-sectional otoscopic and audiological analysis was conducted on 102 cleft palate children (204 ears) aged 1-18 years old who were treated for middle ear effusion at our centre. Retrospective chart review was done to determine patient characteristics and prior patient management. The aim was to assess the effect of ventilation tube insertion (VTI) on hearing, speech and chronic otitis media; comparing the timing and number of ventilation tubes per ear and determining other factors affecting the short-term and long-term outcome.
 
  68 children or 130 ears (63% of all cases) were selectively treated with ventilation tube insertion. Repeat procedures (more than 2) were performed in 41 ears. Among children with VTI performed, the incidence of chronic otitis media in children after the age of 4 was 17%. Overall, abnormal tympanic membrane finvative approach especially when considering repeated tube insertions. A long-term follow-up paired with interval hearing assessment is advocated until early adulthood.
 Treatment with early ventilation tube insertion prior to the age of one year provides a hearing benefit in children less than 4 years of age, but no significant difference after 4 years of age. Factors significantly affecting the outcome after 4 years of age was the timing of palatal closure and total number of tube insertions. We recommend a conservative approach especially when considering repeated tube insertions. A long-term follow-up paired with interval hearing assessment is advocated until early adulthood.The effect of breathing parameters on the airway deposition of the inhaled aerosols with known size was intensively studied in the literature. However, in the case of dry powder aerosol drugs both the quantity and quality of the particles emitted by the inhaler and inhaled by the patients is a complex function of the patient's breathing parameters, which in turn depend also on the disease severity and current status of the patient. The aim of this study was to evaluate the impact of breathing parameters, gender, age, symptoms and exacerbation history related disease severity (GOLD groups) of chronic obstructive pulmonary disease (COPD) patients on the lung dose of four different drugs emitted by three DPIs (dry powder inhalers). Breathing profiles of 47 COPD patients were recorded while they inhaled through Turbuhaler®, Breezhaler® and Genuair® inhalers. Patient specific emitted doses and particle size distributions were determined for Symbicort® Turbuhaler®, Onbrez® Breezhaler®, Seebri® Breezhaler® and Bretaignificantly higher deposition for drugs emitted by Breezhaler® and Genuair®. Lung doses of two different drugs dispensed in the same inhaler can be significantly different.In this study, we examined differences in resting-state functional connectivity between sub-regions of the Default Mode Network (DMN) and whole brain voxels in 22 individuals with high schizo-obsessive traits (SOT), 30 with high schizotypal traits (SCT) alone, 20 with high obsessive-compulsive traits (OCT) alone and 30 with low trait scores (LT). We found that the SOT group showed the most reduced functional connectivity within the DMN compared with the other groups. The SOT group also showed increased connectivity between the DMN and the Salience Network, and between the DMN and the Auditory Network compared with the LT group. The SCT group exhibited increased connectivity between the DMN and the Salience Network, and between the DMN and the Executive Control Network (ECN) compared with the LT group. The OCT group exhibited decreased connectivity within the DMN, between the DMN and the Salience Network, and between the DMN and the ECN compared with the LT group. These findings highlight different changes in DMN-related functional connectivity associated with high SOT, SCT and OCT traits and may provide insight into the dysfunctional brain networks in the early stage of schizophrenia spectrum disorders.
