ABSTRACT
KEY POINTS: SinoNasal Microbiota Transfer (SNMT) was safe with immediate benefit in all recipients, with sustained improvement in two of three recipients for up to 180 days. The addition of antimicrobial photodynamic therapy worsened chronic rhinosinusitis. These promising SNMT results warrant further study of safety and efficacy.
ABSTRACT
Ectopic olfactory neuroblastoma (ONB) is a rare neuroendocrine sinonasal malignancy which arises from sinonasal regions where olfactory neuroepithelium does not exist. Presentation of syndrome of inappropriate antidiuretic hormone release (SIADH) in patients with ectopic ONB is extremely rare. We report a case of a 22-year-old patient with ectopic ONB and paraneoplastic SIADH that was managed at our center. The ONB was arising from the left lamina papyracea and extending into the maxillary and ethmoid sinuses and filling the nasal cavity. Correction of sodium levels occurred within 24 hours of endoscopic resection via a combined trans-nasal transorbital approach. To avoid negative sequela secondary to rapid sodium correction, the patient was managed by desmopressin to obtain gradual sodium correction, which was achieved on the fourth postoperative day. Ectopic presentation of ONB with paraneoplastic SIADH is extremely rare with only 7 cases reported in the literature to date. Management via surgical resection and/or radiotherapy for these patients requires the managing clinician to be vigilant of serum sodium levels. A multidisciplinary approach is essential for optimal outcomes.
ABSTRACT
OBJECTIVE: A deviated nasal septum (DNS) can result in an anatomical obstruction and impact lung function through prolonged suboptimal inspiration. Given the improvements in respiration reported by patients following septoplasty or septorhinoplasty (with or without inferior turbinate reduction), our study investigated the effect of these procedures on pulmonary function through a systematic review and meta-analysis. DATA SOURCES: Medline, Embase, Cochrane Databases, Web of Science, and Google Scholar. REVIEW METHODS: The review was registered with PROSPERO [CRD42022316309]. The study population was composed of adult patients (18-65) who were symptomatic with confirmed DNS. Extracted outcomes (pre-operative versus postoperative) included the six-minute walk test (6MWT) and pulmonary function tests (FEV1, FVC, FEV1/FVC, FEF25-75, PEF). Meta-analyses were performed using a random-effects model. RESULTS: Three studies included measures of the 6MWT in meters and all three found a statistically significant increase in the distance walked after surgery with a mean difference of 62.40 m (95% CI 24.79-100.00). Statistically significant improvements in PFT outcomes were observed with a standard mean difference of 0.72 for FEV1 (95% CI 0.31-1.13), 0.63 for FVC (95% CI 0.26-1.00), and 0.64 for PEF (95% CI 0.47-0.82). Of the twelve studies which measured PFT outcomes, six showed statistically significant improvements, three studies showed mixed results, and three studies found no difference in PFT outcomes between pre-and post-surgery testing. CONCLUSIONS: The present study suggests that pulmonary function does improve after nasal surgery for DNS, but the high heterogeneity observed in the meta-analyses indicates that the evidence supporting this conclusion is low.

Allergic fungal rhinosinusitis (AFRS) is a noninvasive subtype of chronic rhinosinusitis with nasal polyps (CRSwNP) that usually develops in immunocompetent atopic individuals and is more common in geographic regions characterized by warm temperatures and high humidity, conducive to higher environmental fungal presence. Allergic fungal rhinosinusitis usually presents with unique computed tomography findings and significant polyp burden, yet patients often report minimal sinus symptoms. Patients with AFRS often have extremely elevated serum total and fungal-specific IgE levels. Treatment almost always requires surgery, in which adjuvant medical therapy is critical to success. However, until recently the choice of adjuvant therapy has consisted primarily of either oral and/or topical steroids. Although oral corticosteroids decrease recurrence after surgery, data for the effectiveness of other adjunctive pharmacologic agents, including topical and oral antifungal agents and immunotherapy, have remained unclear and hence are not recommended in recent guidelines including the International Consensus of Allergy and Rhinology. Three biologics, omalizumab, dupilumab, and mepolizumab, have recently been approved for treating CRSwNP in general, but clinical trials to date with these biologics did not involve AFRS patients. Recently published case reports and smaller prospective studies have shown good efficacy of these biologics on the AFRS subgroup of patients. This article provides an overview of the understanding of the pathophysiology of AFRS, implications of this understanding on the possible role of biologics, and clinical reports on the use of biologics in treating AFRS. Because biologics are indicated for treating CRSwNP, follow up real-world evidence studies are needed for AFRS.
