Chronic Spontaneous Urticaria Triggered by the AstraZeneca/Oxford COVID-19 Vaccine with Achieved Remission: A Case Report

New adverse reactions to the COVID-19 vaccines are being identified as vaccination rates increase worldwide. Recently, there have been two reports of Moderna (mRNA-1273) vaccine induced relapse of chronic spontaneous urticaria (CSU) that was previously well controlled. Herein, we report a case of AstraZeneca/Oxford (ChAdOx1) vaccine triggered CSU in a patient with no history of CSU with achieved remission.

Cholesterol Granuloma of the Maxillary Sinus—A Case Report and Literature Review

Cholesterol Granulomas of the Maxillary Sinus, considered an unusual presentation at this anatomical site. Over last 2 decades, only few cases are reported in the literature (English) and no available comprehensive reviews or studies on this entity. Herein in this article we present a comprehensive literature review of the available reports of 16 cases along with reporting a new case which we managed, aided with its histopathological pictures. This review article can be a reference for practitioners in the field of otorhinolaryngology who may encounter these cases. Also, it attracts the attention to consider this pathology among the differential diagnoses of nasal masses. Moreover, including a described pathological imaging may help young pathologist to identify this pathology.

Factors Affecting the Control of Chronic Rhinosinusitis With Nasal Polyps: A Comparison in Patients With or Without NERD

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. Mean follow-up time was 9.9 years (range 1.1–15.3). Endpoints reflecting uncontrolled CRSwNP were revision ESS, and need for rescue/advanced therapy (e.g. antibiotics, oral corticosteroids and/or biological therapy) during follow-up. NERD was variable of interest and gender, age, asthma, allergic rhinitis (AR), smoking, Lund-Mackay (LM) score of sinus computed tomography scans previous ESS and baseline total ethmoidectomy were used as covariates. Results Twenty-one (49.7%) NERD patients and 18 (25.7%) non-NERD patients underwent revision ESS within a mean ± SD of 4.3 ± 2.8 and 3.7 ± 2.6 years, respectively (p = .013, by Logrank test). In Cox´s regression models, NERD, female gender, young age, asthma, AR, previous ESS, and lack of total ethmoidectomy were associated with revision-ESS. In adjusted model, only the total ethmoidectomy predicted revision-free survival. In adjusted logistic regression model, there was an insignificant trend that NERD and LM score were associated with the need for rescue/advanced therapy in the follow-up. Conclusions Patients with NERD had higher risk of uncontrolled CRSwNP than patient group without NERD, as measured by revision ESS and/or need for rescue/advanced therapy in the follow-up. In addition, baseline total ethmoidectomy was associated with revision-free survival.

Diagnosis of Anosmia and Hyposmia: A Systematic Review

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. Results A total of 2065 unique titles were returned upon the initial search. Of these, 226 abstracts were examined, yielding 27 full-text articles meeting inclusion criteria (Level of evidence ranging from 1 to 4; most level 2). The studies included a total of 13,577 patients. The most utilized diagnostic tools were orthonasal smell tests (such as the Sniffin’ Sticks and the UPSIT, along with validated abridged smell tests). Though various imaging modalities (including MRI and CT) were frequently mentioned in the workup of olfactory dysfunction, routine imaging was not used to primarily diagnose smell loss. Conclusion The literature includes several studies on validity and reliability for various smell tests in diagnosing anosmia. Along with a thorough history and physical, validated orthonasal smell tests should be part of the workup of the patient with suspected olfactory dysfunction. The most widely studied modality was MRI, but criteria for the timing and sequence of imaging modalities was heterogenous.

Unusual Location of a Fungus Ball: The Concha Bullosa, a Review of the Literature

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. Methods A case of a patient who was diagnosed with concha bullosa of a fungus ball is reported. Demographic data, clinical presentation, imaging, and treatments were recorded. Key images were obtained. A review of the literature was also performed. Results A total of 12 cases have been reported so far in the literature revealed by different symptoms. The mean age was 38.8 years and the gender ratio was ∼12 (female):1 (male). The endoscopic surgical approach was the most frequently used treatment and provides good outcomes. Neither postoperative complications nor recurrences were noted, however, there is insufficient follow-up data. Conclusion Concha bullosa fungal ball is a rare diagnosis that can be revealed by different symptoms. It should be considered in patients with and unexplained chronic facial pain. A preoperative computed tomography scan is an essential tool in making a diagnosis. Endoscopic surgery is the treatment of choice, with a low morbidity and recurrence rate.

Choanal Atresia Repair With Stents and Flaps: A Systematic Review Article

Background Choanal Atresia is an obliteration by an atretic plate of the posterior choanae due to a failure of the bucconasal membrane to rupture. The insertion of stents post choanal atresia repair is familiar. Still, there are limited studies in the literature that specify the time to remove it, the best materials, and the effectiveness of each kind. Objective Our study aims to compare different types of choanal atresia stents and flaps and the outcome of different kinds of stents and flaps that use post-operatively. Also, to assess the risk of restenosis post-operatively with varying types of Stent and flaps. Methods A systematic review via databases for different types of stents and flaps used in choanal atresia, including 31 studies with precise technique, variety of stents, restenosis rates, and risk factors (unilaterality, the component of the atretic plate). And about 10 different approaches to flaps reconstruction were mentioned. Results According to the data, we observed a successful rate of choanal atresia repair by using the ordinary ETT post-operatively ranged from 28 to 94.2%, which could be explained due to many factors. Post-operative Instructions on care and suctioning provided a good impact. Other types of stents found in case series like steroid eluting stents, Nelaton catheters, Silastic stents, or modified ETT have a promising future during 26 to 39 weeks follow-up. Still, they need further studies with randomization and more data. Flaps with different approaches and techniques showed promising results and fewer complication rates with or without stents, also now have been used in practice providing suitable alternatives for stents. Conclusion The original types of choanal atresia stents were shown to have a wide variety of results, while innovative materials of stents showed promising results, however, in relatively small case studies. Flaps were now used in practice giving other choices for stents with fewer complications, better healing, and new choana formation.

Olfactory-Specific Quality of Life Outcomes after Endoscopic Endonasal Surgery of the Sella

Objective To assess olfactory outcomes as measured by an olfactory-specific quality of life (QOL) questionnaire in patients undergoing EESBS for sellar lesions. Design Retrospective case series. Setting Tertiary academic medical center. Participants In total, 36 patients undergoing EESBS for lesions limited to the sella were evaluated. Main Outcome Measures The following were performed before and three months after surgery: 22-Item Sinonasal Outcomes Test (SNOT-22), University of Pennsylvania Smell Identification Test (UPSIT), and the Assessment of Self-reported Olfactory Functioning (ASOF), which has three domains: subjective olfactory capability scale (SOC), smell-related problems (SRP), and olfactory-related quality of life (ORQ). Results Median age at surgery was 52.5 years, with a median tumor size of 1.8 cm (range: 0.2 to 3.9 cm). Pre- and postoperative median scores were 35 [34, 36.2] and 34.5 [32, 36] for UPSIT, 21 [7.5, 33.5] and 21.5 [6.8, 35.7] for SNOT-22, 10 [9, 10] and 9 [8, 10] for ASOF-SOC, 5 [4.8, 5] and 4.5 [4, 5] for ASOF-SRP, and 5 [5, 5] and 5 [4.5, 5] for ASOF-ORQ. There was no significant change in the two of the three domains of the ASOF. Correlation between ASOF and UPSIT scores were weak. Older age and larger tumor size were associated with worsened olfaction after surgery. Conclusions Patients did not experience significant changes in olfactory-specific QOL three months after EESBS, as measured by two domains of the ASOF. The ASOF may serve as a useful adjunctive tool for assessing olfaction after surgery. The lack of correlation between UPSIT and ASOF suggests the need for more research in subjective olfactory-related quality of life after surgery.

Value of Hounsfield Units in the Evaluation of Isolated Sphenoid Sinus Lesions

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. Tissues obtained from the sphenoid sinus were divided into two groups, fungal and nonfungal, according to the findings of histopathologic examinations. HU values were measured in sphenoid sinus sections on paranasal CT scans of these two groups. Differences in mean and maximum HU values between the two groups were statistically significant ( p < .05). The maximum HU values calculated from the sphenoid sinus were 435.08 and 196.23 ( p ≤ .05) in the fungal group and nonfungal group, respectively. The mean HU values calculated from the sphenoid sinus were 64.31 and 29 ( p ≤ .05) in the fungal and nonfungal groups, respectively. At the maximum cutoff value of 241, the sensitivity and specificity of the HU maximum were 84.6% and 77.3%, respectively. At the mean cutoff value of 41.5, the sensitivity and specificity of the HU mean were 76.9% and 86.4%, respectively. HU is an objective value used in radiographic density measurement. The HU values were higher in fungal lesions than in nonfungal inflammations, and they are useful in preoperative measurement.

Qualitative Olfactory Disorders: Patient Experiences and Self-Management

Background Qualitative olfactory disorders in the form of parosmia and phantosmia are very subjective and cannot be measured at present. They pose an unpleasant experience for patients and a therapeutic challenge for clinicians. Objective This study aimed to characterise the specific experiences of patients affected by the qualitative symptoms of parosmia and phantosmia including both triggers for symptoms and self-help measures they have tried. Methods A cross-sectional survey questionnaire was developed with the input of patient experts within the charity Fifth Sense. The survey was then open online for 3 months to charity members complaining of qualitative symptoms. The survey captured the frequency and impact of symptoms and self-management undertaken. Reflective feedback was also captured from a patient workshop. Results There were 100 participants; 61% female, age range 13-88. Common self-reported aetiology included sinonasal disease (17%), idiopathic (33%) and post-viral olfactory loss (26%) and post-traumatic olfactory loss (23%). Parosmia was reported as a daily symptom in 67% compared to 31% for phantosmia; 36% complained of suffering with both symptoms. Only 4% of respondents reported having received any successful treatment for their qualitative symptoms and 58% reported having received no treatment whatsoever. Olfactory training was the most common self-management method reported. Conclusion This study illustrates that qualitative disturbances remain problematic for those who experience them due to the duration of symptoms, the relative lack of experience or knowledge amongst medical professionals and the lack of therapeutic options. In future, consideration needs to be given to adaptation and coping strategies to help patients deal with these symptoms.

Otolaryngologists Practice Pattern on Oral Allergy Syndrome

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. A survey was designed to include demographic questions and questions about OAS understanding, screening, and management. Surveys were sent to selected otolaryngologists via mail. Responses were de-identified and analyzed using SPSS. Results Out of the 50 survey responses, 46 reported treating environmental allergy in their practices. Twenty eight out of 46 reported knowing about OAS (60.9%). Fifteen out of the 28 physicians screened for OAS (53.6%). Out of the responders who knew about OAS, 12 (42.9%) reported diagnosing under 5 cases in the past year, 7 (25%) diagnosed 5 to 10 cases, and 7 (25%) reported diagnosed more than 10 cases in the past year. Eleven (39.3%) reported ordering component allergy testing for food allergies. Twenty six (92.9%) reported using avoidance, 18 (64.3%) prescribed oral antihistamine medications, 14 (50%) prescribed epi-pen, and 19 (67.9%) desensitized patients to environmental allergies as a treatment for OAS. 26 (93%) reported using more than one of the listed treatments. 10 (36%) reported using all four methods. Conclusion Only 60.9% of the responders had a knowledge of OAS. Only 53.6% of those screened for OAS. Current treatment for OAS includes avoidance of allergens, desensitization of environmental allergens, prescription of oral antihistamine and epi-pen. Nearly everyone (93%) reported using more than one treatment method.
