The objective of this study is to analyse surgical outcomes in a series of patients who underwent subtotal petrosectomy in combination with cochlear implantation. Retrospective chart review. Thirty patients (32 ears) underwent subtotal petrosectomy and cochlear implantation in one stage. Indications for subtotal petrosectomy included the following cholesteatoma, chronic otitis media, previous canal wall-down, osteoradionecrosis, revision surgery for clinical reasons, inner ear malformations, middle ear anatomical variations and severe cochlear ossification. Follow-up ranged from 2 to 54 months. Only 2 complications related to the subtotal petrosectomy (1 subcutaneous abdominal haematoma and 1 subcutaneous abdominal seroma) occurred in this series. Complete electrode insertion was achieved in all but 4 cases. Subtotal petrosectomy is a safe procedure and can offer technical advantages in some cases of complex cochlear implantation. Subtotal petrosectomy is a safe procedure and can offer technical advantages in some cases of complex cochlear implantation. The purpose of this study was to assess vestibular findings and clinical history in a large cohort of patients affected by Ménière's disease. We retrospectively analysed 511 adult patients fulfilling criteria for definite unilateral Ménière's disease according to Barany Society. Thorough clinical history, audiometric exam, central nervous system MRI, quantification of serum autoantibodies and complete vestibular function test were performed. Mean age at clinical record was 55.4 years, while age at onset of the first vertigo attack was 47.4 ± 14.3 years. Ménière's disease overlapped with migraine in 43.4% of patients. In 31.7% of cases, positivity was found for at least one autoantibody. Forty-nine patients (9.6%) had family history for Ménière's disease. Bedside examination resulted in 14.7% positivity for video head impulse test, 58.9% for skull vibration-induced nystagmus, 38.7% for the positional test and 23.1% for the post head shaking test. Complete negative examination was reported in 115 cases. Ménière's disease was seen to present a characteristic phenotypic pattern in our cohort, confirming the crucial role of thorough anamnesis and bedside examination in diagnosis.

The introduction of monoclonal antibody (mAb) therapies represents a promising treatment for refractory chronic rhinosinusitis (CRS). We assessed the effects of selected mAbs (omalizumab, mepolizumab, benralizumab) on CRS in severe asthmatic patients in a real-life setting. A prospective observational study on severe asthmatic patients, treated with 3 different mAb (omalizumab, mepolizumab, benralizumab), and comorbid CRS was conducted. All patients were followed for 52 weeks. The degree of nasal control, SinoNasal Outcome Test (SNOT) 22, Nasal Polyp Score (NPS), Lund Kennedy Score (LKS) were collected at baseline and at 52-week. 40 patients (33 with nasal polyps) were studied. 33 patients (82.5%) had uncontrolled nasal disease at baseline, and 15 (37.5%) were uncontrolled after 52 weeks. Significant improvement was observed for SNOT 22 (P < 0.001), SNOT 1-12 (P < 0.001) and degree of nasal control (P < 0.001). Differences in NPS (P = 0.130) and LKS (P = 0.124) were not significant. Net change in the above-mentioned parameters among the three treatment groups was not significantly different. The study shows an improvement of nasal symptoms after 52 weeks of mAb treatment, which was not associated with significant improvement of endoscopic findings. Larger studies are needed to assess the real-life efficacy of mAbs in CRS.

Over the years, evidence-based data and technical improvements have consolidated the central role of radiation therapy (RT) in head and neck cancer (HNC) treatment, even in the elderly. This survey aimed to describe the management of the elderly HNC patients among Italian Radiation Oncology Departments (RODs) and provide possible suggestions for improvement. An online survey based on 43 questions was sent to RODs via email. For each RODs, a radiation oncologist with expertise in HNC was invited to answer questions addressing his/her demographic data, ROD multidisciplinary unit (MU) organisation and ROD management policy in elderly HNC patients. In total, 68 RODs answered, representing centres located in 16 Italian regions. MU was considered the core of HNC patient management in almost all the entire country. https://www.selleckchem.com/products/CP-690550.html However, in many RODs, there was minimal access to a routinely comprehensive geriatric assessment at diagnosis. Most treatments were reported by respondents as curative (89% on average) and the preferred treatment technique was intensity modulated radiation therapy (IMRT). A considerable variation between RODs was found for RT target volumes. There was a relation between the specialist's years of experience and type of concomitant systemic therapy prescribed. Substantial differences in elderly HNC management have been found, especially concerning patient clinical evaluation and target volume delineation. This survey shows the necessity to design a prospective national trial to provide a uniform treatment strategy and define an effective patient-centred approach.

Pol III, the largest nuclear RNA polymerase, is composed of a conserved core region and eight constitutive regulatory subunits, but how these factors jointly regulate Pol III transcription remains unclear. Here, we present cryo-EM structures of human Pol III in both apo and elongating states, which unveil both an orchestrated movement during the apo-to-elongating transition and an unexpected apo state in which the RPC7 subunit tail occupies the DNA-RNA-binding cleft of Pol III, suggesting that RPC7 plays important roles in both autoinhibition and transcription initiation. The structures also reveal a proofreading mechanism for the TFIIS-like subunit RPC10, which stably retains its catalytic position in the secondary channel, explaining the high fidelity of Pol III transcription. Our work provides an integrated picture of the mechanism of Pol III transcription regulation.
