Socioeconomic, comorbidity, lifestyle, and quality of life comparisons between chronic rhinosinusitis phenotypes.

Background: Chronic rhinosinusitis (CRS) is a heterogeneous group of inflammatory sinonasal disorders with key defining symptoms, but traditionally separated into phenotypes by clinical/endoscopic findings. It is not known whether the two phenotypes have differing socioeconomic, comorbidity, and lifestyle differences. This analysis of the Chronic Rhinosinusitis Epidemiology Study (CRES) database sought to analyze any key differences in the socioeconomic variables between those with CRS with nasal polyps (CRSwNPs) and those without nasal polyps (CRSsNPs).

Photodynamic Therapy as a New Treatment for Chronic Rhinosinusitis - A Systematic Review.

This review examines the latest evidence for photodynamic therapy (PDT) in treating chronic rhinosinusitis. MedLine, EMBASE and TRIP Database searches were conducted using the terms: "photodynamic" or "phototherapy" or "photo" and "sinusitis" or "rhinosinusitis," date range January 2000 to May 2020. A total of 192 records were initially identified, after duplicates and exclusions, 9 full papers and 3 abstracts were included.

Exploring the association between ingestion of foods with higher potential salicylate content and symptom exacerbation in chronic rhinosinusitis. Data from the National Chronic Rhinosinusitis Epidemiology Study.

Introduction: Pharmacological salicylates are known to trigger respiratory exacerbations in patients with Non-Steroidal Exacerbated Respiratory Disease (N-ERD), a specific phenotype of Chronic Rhinosinusitis (CRS) and asthma. The impact of dietary sources of salicylates across subgroups of CRS is not well understood. The hypothesis is that in patients with nasal polyps present, there is likely to be a higher incidence of symptom exacerbation due to dietary salicylates regardless of any known response to pharmacological salicylate.

Assessing and treating adult patients with hearing loss.

Hearing loss is a very common presentation both in primary and secondary care. In addition to causing significant morbidity, it can make communication with patients very challenging, and thus impact other aspects of their care. This article presents an approach to the assessment and management of this condition.

Current use of baseline medical treatment in chronic rhinosinusitis: Data from the National Chronic Rhinosinusitis Epidemiology Study (CRES).

Objectives: According to clinical and comissioning guidelines for chronic rhinosinusitis (CRS), patients being referred to secondary care should have failed primary medical treatment with nasal douching (ND) and intranasal corticosteroids (INCS). The study objectives were to identify the rate of specific medical therapy in CRS patients and establish any differences in medication use, for both CRS and associated medical conditions, between CRS phenotypes.

Design And Setting: Case-control study in a secondary care setting.

Multicentre prospective clinical application of the T14 paediatric outcome tool.

Objective: This study aimed to measure changes in disease-specific quality of life in children following tonsillectomy or adenotonsillectomy.

Methods: A multicentre prospective cohort study was performed involving seven ENT departments in England. A total of 276 children entered the study over a 2-month period: 107 underwent tonsillectomy and 128 adenotonsillectomy.

The burden of revision sinonasal surgery in the UK-data from the Chronic Rhinosinusitis Epidemiology Study (CRES): a cross-sectional study.

Objectives: The aim of this study was to investigate the surgical revision rate in patients with chronic rhinosinusitis (CRS) in the UK CRS Epidemiology Study (CRES). Previous evidence from National Sinonasal Audit showed that 1459 patients with CRS demonstrated a surgical revision rate 19.1% at 5 years, with highest rates seen in those with polyps (20.

Lessons learnt from the diagnosis and antimicrobial management of necrotising (malignant) otitis externa: our experience in a tertiary referral centre.

Necrotising otitis externa is an uncommon and aggressive infection of the external auditory canal with a tendency to present in the elderly and immunocompromised patient. We report a series of twenty-five patients admitted to our institution over a four-year period with this diagnosis. We review the diagnosis and antimicrobial management of these cases, and propose a treatment algorithm based on our experience.

Skin graft survival on subcutaneous hinge flaps: an algorithm for nasal reconstruction.

Objectives/hypothesis: To assess the survival of full-thickness skin grafts and perichondrial cutaneous grafts when placed on subcutaneous soft tissue flaps used in nasal reconstruction.

Study Design: Retrospective case series from a secondary-care cutaneous cancer practice.

Methods: Twenty-eight patients with nasal defects secondary to basal cell carcinoma excision were included.

Cysteinyl leukotriene type I receptor desensitization sustains Ca2+-dependent gene expression.

Receptor desensitization is a universal mechanism to turn off a biological response; in this process, the ability of a physiological trigger to activate a cell is lost despite the continued presence of the stimulus. Receptor desensitization of G-protein-coupled receptors involves uncoupling of the receptor from its G-protein or second-messenger pathway followed by receptor internalization. G-protein-coupled cysteinyl leukotriene type I (CysLT1) receptors regulate immune-cell function and CysLT1 receptors are an established therapeutic target for allergies, including asthma.

An evidence based review of the assessment and management of penetrating neck trauma.

Background: Although relatively uncommon, penetrating neck trauma has the potential for serious morbidity and an estimated mortality of up to 6%. The assessment and management of patients who have sustained a penetrating neck injury has historically been an issue surrounded by significant controversy. OBJECTIVES OF REVIEW: To assess recent evidence relating to the assessment and management of penetrating neck trauma, highlighting areas of controversy with an overall aim of formulating clinical guidelines according to a care pathway format.

Is surgical debridement and topical 5 fluorouracil the optimum treatment for woodworkers' adenocarcinoma of the ethmoid sinuses? A case-controlled study of a 20-year experience.

Objectives: Woodworkers' adenocarcinoma of the ethmoid sinuses is an extremely rare occupational malignancy with a locally aggressive course. Treatment with surgical exenteration and topical 5 fluorouracil (5FU) packs has become standard treatment over the last 10 years in this ENT unit. This study presents level 2 evidence that 5FU provides improved survival over previous management with primary radiotherapy and salvage craniofacial resection.

Evidence-based medicine as a tool for clinical decision-making in Puerto Rico.

Evidence-based medicine (EBM) is defined as "the process of systematically finding, appraising and using contemporaneous research findings as the basis for clinical decisions". Although EBM has been extensively described across the Americas and Europe, no study has looked at the practice of EBM in Puerto Rico. A cross-sectional analysis based on a 23-item questionnaire was employed.

Silicone Foley catheters outperform latex Foley catheters for post-nasal packing: an in-vitro study.

Objectives: To determine the best Foley catheter and inflation fluid for post-nasal packing.

Design: Experimental study.

Setting: District General Hospital (Wexham Park Hospital).

Inflammatory pseudotumour of the neck with multifocal sites on positron emission tomography scan imaging.

We present a patient with an inflammatory pseudotumour of the neck with multifocal sites in the head and chest responding to steroids. A review of the literature revealed that this is the first case of a pseudotumour with multiple sites in the head and neck as revealed by 2-[18]fluorodeoxyglucose (FDG) PET scan imaging.

Use of isotope ratios to identify sources contributing to pediatric lead poisoning in Peru.

In 1998, a school-based blood lead level (BLL) survey of 2,510 children, conducted in Lima and Callao, Peru, revealed elevated BLLs in children from 2 Callao schools (mean BLL = 25.6 microg/dl; n = 314) and in children from Callao overall (mean BLL = 15.2 microg/dl; n = 898), compared with children from Lima (mean BLL = 7.
