003) and use of preoperative steroids in patients with sinonasal polyposis was associated with lower POD1 pain scores (
= .03).

Even on POD1, majority of patients experienced either mild or no pain, and this decreases with each POD. Narcotics are grossly overprescribed and underutilized by patients postoperatively after FESS. We advocate for more judicious prescribing habits of narcotics by Otolaryngologists after FESS, and emphasize relying on non-narcotic alternatives like Acetaminophen or NSAIDS to diminish narcotic use and abuse in the postoperative period.

Phototherapy with narrow-band ultraviolet B (narrow-band UVB) is clinically effective treatment for atopic dermatitis. In the present study, we examined the effects of intranasal irradiation with narrow-band UVB on nasal symptom, upregulation of histamine H
receptor (H1R) gene expression and induction of DNA damage in the nasal mucosa of allergic rhinitis (AR) model rat.

AR model rats were intranasally irradiated with 310 nm of narrow-band UVB. Nasal mucosal levels of H1R mRNA were measured using real-time quantitative reverse transcriptase (RT)-PCR. DNA damage was evaluated using cyclobutane pyrimidine dimer (CPD) immunostaining.

In toluene 2,4-diisocyanate (TDI)-sensitized rats, TDI provoked sneezes and H1R gene expression in the nasal mucosa. Intranasal pre-irradiation with 310 nm narrow-band UVB at doses of 600 and 1400, but not 200 mJ/cm
significantly inhibited the number of sneezes and upregulation of H1R gene expression provoked by TDI. CPD-positive cells appeared in the nasal mucosa after intranasal narrow-band UVB irradiation at a dose of 1400, but not 200 and 600 mJ/cm
. The suppression of TDI-provoked sneezes and upregulation of H1R gene expression lasted 24 hours, but not 48 hours, after narrow-band UVB irradiation with a dose of 600 mJ/cm
.

Intranasal pre-irradiation with narrow-band UVB dose-dependently inhibited sneezes and upregulation of H1R gene expression of the nasal mucosa in AR model rats, suggesting that the inhibition of nasal upregulation of H1R gene expression suppressed nasal symptom. The suppression after narrow-band UVB irradiation at a dose of 600 mJ/cm
was reversible without induction of DNA damage. These findings indicated that low-dose narrow-band UVB phototherapy could be effectively and safely used for AR treatment in a clinical setting.

Previous investigations suggest the use of extract from the roots of
(EPs 7630) for the therapy of uncomplicated rhinosinusitis. The aim of this prospective study was to compare the effects of herbal drug EPs 7630 and antibiotic roxithromycin on chemokine production in nasal mucosa and clinical parameters in patients with uncomplicated acute bacterial rhinosinusitis (ABRS).

Seventy-eight ABRS patients were divided into 26 patients receiving EPs 7630 tablets, 3 × 20 mg/day per os (group 1), 26 patients receiving roxithromycin tablets, 2 × 150 mg/day per os (group 2), both for 10 days, and 26 patients who received no therapy (Control group). We measured chemokine levels in nasal secretions by flow cytometry and assessed clinical parameters on day 0 and day 10 of investigation.

EPs 7630 increased concentrations of MCP-1 (
= .001) and IP-10 (
= .049) and decreased levels of MIP-1α (
 < .001), ENA-78 (
 < .001), and IL-8 (
 < .001). Roxithromycin increased levels of IP-10 (
= .049) and decreased levels of MCP-1 (
 < .001), MIP-1α (
 < .016), ENA-78 (
 < .001), and IL-8 (
 < .001). Comparison of the non-treated patients' group with groups 1 and 2 revealed significant improvement of all clinical parameters in treated patients (
 < .001), but therapy with roxithromycin resulted in better improvement in nasal symptoms and endoscopic findings than therapy with EPs 7630.

Our results suggest the presence of similar modulatory effects of both therapies on production of chemokines that regulate the function of neutrophils and monocytes in nasal mucosa. Roxithromycin shows better clinical efficacy than EPs 7630 in patients with uncomplicated ABRS.

Data on the pathogenesis of anosmia during COVID-19 suggest potential olfactory nerve involvement. Zinc is an essential micronutrient that regulates the immune responses, and zinc deficiency is known to induce anosmia and ageusia. We previously proposed that a drop in nasal zinc level is a normal nasal immune response to acute viral infections, including SARS-CoV-2 infection, and play a role in the pathogenesis of anosmia. learn more The drop in the local zinc level in response to SARS-CoV-2 may lead to lower type 1 interferons and shift toward Th2 immune responses; if prolonged, it may lead to increased viral replication and more severe disease. In people who are at risk for baseline systemic zinc deficiency, such as the elderly and those with chronic diseases such as, chronic lung disease, diabetes, cardiovascular disease, and cancer, SARS-CoV-2 infection-induced drop in nasal zinc level may be more severe and prolonged and lead to an insufficient anti-viral nasal immune response and control the spread of the virus systemically and to the lungs. A better understanding of the clinical implications of baseline systemic zinc deficiency on anosmia and nasal immune responses may allow the development of new treatment strategies to slow down or stop the systemic invasion of SARS-CoV-2.
To determine the demographics, presentation, management, and outcomes of patients with recurrent angioedema. To compare the findings to patients with ACE inhibitor related angioedema.

Retrospective case series with chart review of patients who presented to a tertiary-care hospital between January 2010 and December 2017 with two or more episodes of angioedema. Excluded were patients with anaphylactic reaction, medication induced angioedema, or angioedema secondary to an infectious etiology. A group of 88 patients who presented during the same time period with ACE inhibitor related angioedema was used as a control. Statistical analysis was conducted using a two-tailed Fisher exact test and a multivariate logistical regression model to determine significant associations.

Ninety-one patients were identified; 61 met the selection criteria and had 217 total episodes of angioedema episodes presenting to the emergency department. Fifty percent were Caucasian or Hispanic. The average number of episodes was 3.5 (range 2-23).
