We report the case of a 67-year-old female with hypertension and rheumatoid arthritis who had 5 unprovoked episodes of anaphylaxis in an 18-month period of time. We review idiopathic anaphylaxis, including its definition, diagnostic work-up, and differential diagnosis.

INTRODUCTION: The fungal balls of the paranasal sinuses are usually seen in the maxillary and sphenoid sinuses. Although, the lesion of the concha bullosa, without sinus participation, is very uncommon. We report the case of a fungal ball of concha bullosa in an 88-year-old patient. OBJECTIVE: The objective of our review of literature is to investigate the epidemiological, clinical, paraclinical, and therapeutic characteristics of patients diagnosed with fungus ball in concha bullosa...

Radiologic findings of fungal sinus disease are generally opacification in paranasal computed tomography (CT) images. The Hounsfield unit (HU) is a standardized objective unit that is also suitable for measuring remodeling and opacifications on CT scans of bone sections of patients with chronic rhinosinusitis. We hypothesized that HU values could provide valuable information in isolated sphenoid sinus lesions before surgery. Between 2012 and 2019, 35 patients underwent functional endoscopic sinus surgery for sphenoid sinus lesions...

Although inferior turbinectomy with submucosal resection effectively reduces the volume of the inferior turbinate, there is room for improvement in surgical procedures. Techniques have been developed to reduce crusting and bleeding while efficiently achieving volume reduction. State-of-the-art procedures pertaining to the local injection site, incision line, exposure of the periosteum, submucosal outfracture of the turbinate bone, trimming of redundant mucosa, and incision line suturing are described. Pre and postoperative Nasal Obstruction Symptom Evaluation (NOSE) scores and postoperative inferior turbinate bleeding and crusting were evaluated...

BACKGROUND: Anosmia and hyposmia have many etiologies, including trauma, chronic sinusitis, neoplasms, and respiratory viral infections such as rhinovirus and SARS-CoV-2. We aimed to systematically review the literature on the diagnostic evaluation of anosmia/hyposmia. METHODS: PubMed, EMBASE, and Cochrane databases were searched for articles published since January 1990 using terms combined with Medical Subject Headings (MeSH). We included articles evaluating diagnostic modalities for anosmia, written in the English language, used original data, and had two or more patients...

Chronic spontaneous urticaria (CSU, chronic idiopathic urticaria) is a clinical diagnosis characterized by recurrent urticaria of unknown origin, with or without angioedema, that occurs for six weeks or longer. Management of CSU includes a second-generation H1 antihistamine and/or elimination of exacerbating factors. If initial treatment is unsuccessful, trials of first generation H1 antihistamine, H2 blocking antihistamine, leukotriene-receptor antagonist, anti-inflammatory or immunosuppressive agents may be administered...

Introduction: The SARS-CoV-2 virus has infected more than 63,000,000 people worldwide after emerging from Wuhan, China in December 2019. This outbreak was declared a Public Health Emergency in January 2020, and a pandemic in March. While rare, reinfection with the virus has been reported on multiple occasions. Case Presentation: We present a case report of an individual with mannose binding lectin deficiency who tested positive on two separate occasions, months apart, and did not develop IgG antibodies to SARS-CoV-2...

Study Design: Retrospective review of patients undergoing sinus surgery for indication of chronic rhinosinusitis with and without nasal polyposis. Setting: Tertiary referral center. Participants: Patients who underwent FESS from 2008-2017; excluding skull base, craniofacial, or oncologic surgery. Primary study group were patients aged 65 years and older...

BACKGROUND: Oral allergy syndrome is a unique type of food allergy caused by cross-sensitivity between inhalant allergens and food allergens. Despite its significant prevalence and potentially serious outcome, the knowledge base and practice patterns on OAS are not well known among otolaryngologists. Our study is designed to understand the practice patterns of otolaryngologists in screening, testing, and treating OAS through a web-based survey. METHODS: Three thousand otolaryngologists were randomly selected from a membership list of the American Academy of Otolaryngology - Head and Neck Surgery...

INTRODUCTION: Anaphylaxis to jackfruit (Artocarpus heterophyllus) is rare. Two previously reported cases have been published in two healthcare workers from jackfruit endemic regions. Latex allergy and birch pollen cross reactivity have both been associated with jackfruit anaphylaxis, providing two separate mechanisms of sensitization. We present a case of jackfruit anaphylaxis in a young latex allergic non-healthcare worker in a non-endemic region. CASE REPORT: A 21-year-old male had an anaphylactic reaction immediately after ingesting dried jackfruit...

Background: The most severe thunderstorm asthma (TA) event occurred in Melbourne on the 21st November 2016 and during this period, daily pollen information was available and accessible on smart devices via an App. An integrated survey within the App allows users to self-report symptoms. Objective: To explore patterns of symptom survey results during the period when the TA event occurred. Methods: Symptom data from the Melbourne Pollen Count and Forecast App related to asthma history, hay fever symptoms, and medication use was explored...

OBJECTIVES: The aim was to compare the control of chronic rhinosinusitis with nasal polyps (CRSwNP) after endoscopic sinus surgery (ESS), in patients with/without nonsteroidal anti-inflammatory drug exacerbated respiratory disease (NERD). Study Desing : A retrospective hospital-based sample of CRSwNP patients with/without NERD with follow-up. SETTING: Tertiary rhinology centers. METHODS: Electronic patient record data from 116 CRSwNP patients (46 with NERD and 70 without NERD) undergoing ESS during 2001-17 were studied...

BACKGROUND: Various graft materials that are classified as autografts, xenografts, and allografts based on their origin have been used to endoscopically repair skull base defects. Tutoplast® (Tutogen Medical GmbH), an allogeneic natural collagen matrix, is processed through chemical sterilization that preserves tissue biocompatibility and structural integrity. OBJECTIVE: To study the safety and efficacy of Tutoplast Fascia Lata and Tutoplast Temporalis Fascia® as primary graft materials in the endoscopic reconstruction of skull base defects of different sizes and etiologies and to compare the outcomes with those of other traditional graft materials based on our experience...

Meningitis remains a rare but potentially life-threatening intracranial complication of acute rhinosinusitis. We describe a case of a 62-year-old man with a background of chronic rhinosinusitis who presented to hospital with confusion, fever and bilateral green purulent rhinorrhoea. After immediate sepsis management, urgent contrast-enhanced computed tomography head revealed opacification of all paranasal sinuses and bony erosion of the lateral walls of both ethmoid sinuses. He was treated with intravenous antibiotics, topical nasal steroids, decongestants and irrigation...

Background: The Taiwan Smell Identification Test (TWSIT) was developed and successfully administered in Taiwanese population since 2015. However, for sanitation reason, the original liquid-jar form of this test is not appropriate. The commercialized TWSIT was then re-designed as "scratch-and-sniff" version: the TIBSIT (Top International Biotech, Taipei, Taiwan). This project aims to investigate the normative value of TIBSIT in different age groups and genders. Methods: Volunteers aged 20 to 80 with no subjective smell loss were recruited in a rhinology clinic...

OBJECTIVES: YouTube is the second most visited website in the world and can be a useful resource for patients to gain insight into surgical procedures. A multitude of studies have evaluated the quality of otolaryngology-specific healthcare information available on the YouTube platform, but to our knowledge, the online content regarding functional endoscopic sinus surgery available on this site has not been systematically evaluated. STUDY DESIGN: Cross sectional study...

Background: Primary ciliary dyskinesia (PCD) is characterised by an imbalance in mucociliary clearance leading to chronic respiratory infections. Cilia length is considered to be a contributing factor in cilia movement. Recently, IFT46 protein has been related to cilia length. Therefore, this work aims to study IFT46 expression in a PCD patients cohort and analyse its relationship with cilia length and function, as it was not previously described. Materials and methods: The expression of one intraflagellar transport ( IFT46 ) and two regulating ciliary architecture ( FOXJ1 and DNAI2 ) genes, as well as cilia length of 27 PCD patients, were measured...

Background: Chronic rhinitis is a common condition generally treated with medical therapies. However, 10-22% of patients are refractory to medical therapies. A cryotherapy handheld device targeting the postganglionic nerve fibers of the posterior nasal nerve (PNN) now serves as an additional option for therapy. This study evaluates the efficacy of the cryosurgical ablation device of the PNN in the clinic setting. Methods: This was a prospective single-arm trial of 24 adult patients at seven locations within a large health maintenance organization...
