Previous studies on the relationship between olfaction and depression have revealed mixed results. In addition, few have focused on the reciprocity of this association. The aim of this study is to ...combine depression and olfactory data in two separate patient populations to further understand their association. A systematic literature review was conducted using 3 online databases to identify studies correlating olfaction and depression in patients presenting with either primary depression or primary olfactory dysfunction. For the depressed population, weighted means and standard deviations for the Sniffin' Sticks Test and the 40-item Smell Identification Test were combined using 10 studies. For the olfactory dysfunction population, weighted means of Beck's Depression Inventory were combined using 3 studies. Independent t-tests were used to compare differences between groups. Comparing primary depressed patients with controls, depressed patients showed decreased scores in olfactory threshold (6.31±1.38 vs. 6.78±0.88, P = 0.0005), discrimination (12.05±1.44 vs. 12.66±1.36, P = 0.0073), identification (12.57±0.74 vs. 12.98±0.90, P < 0.0001), and 40-Item Smell Identification Test (35.31±1.91 vs. 37.41±1.45, P < 0.0001). In patients with primary olfactory dysfunction, Beck's Depression Inventory scores were significantly different between patients classified as normosmics, hyposmics and anosmics (5.21±4.73 vs. 10.93±9.25 vs. 14.15±5.39, P ≤ 0.0274 for all 3 comparisons). In conclusion, patients with depression have reduced olfactory performance when compared with the healthy controls and conversely, patients with olfactory dysfunction, have symptoms of depression that worsen with severity of smell loss.
Background With a focus on patient-centered care, there is increasing policy interest in patient-reported outcome measures (PROMs) to inform improvements in health care delivery. Given the importance ...of understanding patient-reported outcomes during the management of chronic rhinosinusitis (CRS), PROMs will play an essential role in informing and tailoring the right intervention to the right patient. Objective The objective of this systematic review was to identify and assess the quality of PROMs being used for adults with CRS. Methods A systematic review of Ovid MEDLINE (R) (1947-May 2015), Embase, and the Cochrane databases was performed using the following key terms: “chronic” AND “*sinusitis” AND PROM OR patient reported outcome measure* OR quality of life OR questionnaire OR survey OR valid* OR develop*. An unlimited truncation strategy (placement of *) was used to capture all variations of terms used. The quality of each PROM was assessed and reported using standardized criteria from the COnsensus-based Standards for the selection of health status Measurement INstruments checklist. Results A total of 15 PROMs validated for use in adult patients with CRS were identified. Fourteen instruments were specific to adults with CRS, and one was a generic quality-of-life instrument (EuroQol five-dimensional questionnaire EQ-5D). There was significant variation in the quality of development and reporting of psychometric properties. Overall, the highest quality validated PROMs for adults with CRS were (1) the 22-item Sinonasal Outcome Test (19 points), (2) the Questionnaire of Olfactory Disorders (14 points), (3) the Sinusitis Control Test (14 points), and (4) the EQ-5D (13 points). Most of the PROMs were developed for research purposes such as determining changes in health-related quality of life or symptoms after an intervention as opposed to improving clinical decision making. Conclusions Based on quality assessment, the 22-item Sinonasal Outcome Test, the Questionnaire of Olfactory Disorders, and the Sinusitis Control Test provided the highest quality CRS-specific PROMs, whereas the EQ-5D provided the highest quality generic quality-of-life instrument. Future CRS PROMs will need to incorporate clinical domains that assess common comorbid diseases along with patient values and preferences to improve clinical decision making.
Given the relationship between allergic rhinitis (AR) and asthma, it can be hypothesized that reducing inflammation in the upper airway with intranasal corticosteroid (INCS) medications may improve ...asthma outcomes. The goal of this study was to perform a systematic review with meta‐analysis of the efficacy of INCS medications on asthma outcomes in patients with AR and asthma. Asthma‐specific outcomes from randomized, controlled studies evaluating INCS medications in patients with AR were evaluated, including studies that compared INCS sprays to placebo, INCS sprays plus orally inhaled corticosteroids to orally inhaled corticosteroids alone, and nasally inhaled corticosteroids to placebo. Sufficient data for meta‐analysis were retrieved for 18 trials with a total of 2162 patients. Asthma outcomes included pulmonary function, bronchial reactivity, asthma symptom scores, asthma‐specific quality of life, and rescue medication use. The subgroup of studies comparing INCS spray to placebo had significant improvements in FEV1 (SMD = 0.31; 95% CI, 0.04–0.58), bronchial challenge (SMD = 0.46; 95% CI, 0.12–0.79), asthma symptom scores (SMD = −0.42; 95% CI, −0.53 to −0.30), and rescue medication use (SMD = −0.29; 95% CI, −0.58 to −0.01). Nasal inhalation of corticosteroids significantly improved morning and evening peak expiratory flow. There were no significant changes in asthma outcomes with the addition of INCS spray to orally inhaled corticosteroids. Thus, the results of this meta‐analysis demonstrated that intranasal corticosteroid medications significantly improve some asthma‐specific outcome measures in patients suffering from both AR and asthma. This effect was most pronounced with INCS sprays when patients were not on orally inhaled corticosteroids, or when corticosteroid medications were inhaled through the nose into the lungs. Overall, intranasal corticosteroid medications improve some asthma‐specific outcome measures in patients with both AR and asthma. Further research is needed to clarify the role of INCS sprays as asthma‐specific therapy, as well as the role of the nasal inhalation technique as a monotherapy in patients suffering from both asthma and AR.
Background
Olfactory dysfunction (OD) is common and has been reported as an early indicator of COVID-19. However, the reported prevalence of OD in the general population varies widely depending upon ...the metric used to assess olfaction.
Methodology/Principal: To perform a systematic review and meta-analysis of the prevalence of OD in the healthy general population, review the various assessment metrics used, and compare pooled OD prevalence rates.
Results
A total of 175,073 subjects were identified (mean age 63.5 years, range 18 to 101) with an overall OD prevalence of 22.2% (95% CI 14.8–30.6). OD prevalence was significantly greater using objective olfactory assessments, compared to subjective measures (28.8%, CI 20.3–38.2 versus 9.5%, CI 6.1–13.5, p < 0.001). The prevalence of OD was greater using expanded identification tests (>8 items) compared to brief test with ≤8 items (30.3%, CI 16.2–46.5 versus 21.2%, CI 12.3–31.8). Prevalence was higher in studies with a mean age greater than 55 years compared to those with a mean age of 55 years or less (34.5%, CI 23.4–46.5 versus 7.5%, CI 2.6–14.5, p < 0.001).
Conclusions
The reported prevalence of OD in the general population depends on the testing method and population age. OD prevalence was greater in studies using objective tests, expanded identification tests, and in those with older subjects.

Acne is one of the most common disorders treated by dermatologists and other health care providers. While it most often affects adolescents, it is not uncommon in adults and can also be seen in ...children. This evidence-based guideline addresses important clinical questions that arise in its management. Issues from grading of acne to the topical and systemic management of the disease are reviewed. Suggestions on use are provided based on available evidence.
Background Current clinical classifications of chronic rhinosinusitis (CRS) have weak prognostic utility regarding treatment outcomes. Simplified discriminant analysis based on unsupervised ...clustering has identified novel phenotypic subgroups of CRS, but prognostic utility is unknown. Objective We sought to determine whether discriminant analysis allows prognostication in patients choosing surgery versus continued medical management. Methods A multi-institutional prospective study of patients with CRS in whom initial medical therapy failed who then self-selected continued medical management or surgical treatment was used to separate patients into 5 clusters based on a previously described discriminant analysis using total Sino-Nasal Outcome Test-22 (SNOT-22) score, age, and missed productivity. Patients completed the SNOT-22 at baseline and for 18 months of follow-up. Baseline demographic and objective measures included olfactory testing, computed tomography, and endoscopy scoring. SNOT-22 outcomes for surgical versus continued medical treatment were compared across clusters. Results Data were available on 690 patients. Baseline differences in demographics, comorbidities, objective disease measures, and patient-reported outcomes were similar to previous clustering reports. Three of 5 clusters identified by means of discriminant analysis had improved SNOT-22 outcomes with surgical intervention when compared with continued medical management (surgery was a mean of 21.2 points better across these 3 clusters at 6 months, P < .05). These differences were sustained at 18 months of follow-up. Two of 5 clusters had similar outcomes when comparing surgery with continued medical management. Conclusion A simplified discriminant analysis based on 3 common clinical variables is able to cluster patients and provide prognostic information regarding surgical treatment versus continued medical management in patients with CRS.
Doublecortin-like kinase 1 (Dclk1), a microtubule-associated kinase, marks the fifth lineage of intestinal epithelial cells called tuft cells that function as tumor stem cells in Apc mutant models of ...colon cancer. In order to determine the role of Dclk1 in dextran sulfate sodium (DSS) induced colonic inflammation both intestinal epithelial specific Dclk1 deficient (VillinCre;Dclk1f/f) and control (Dclk1f/f) mice were fed 3% DSS in drinking water for 9 days, allowed to recover for 2 days, and killed. The clinical and histological features of DSS-induced colitis were scored and immunohistochemical, gene expression, pro-inflammatory cytokines/chemokines, and immunoblotting analyses were used to examine epithelial barrier integrity, inflammation, and stem and tuft cell features. In DSS-induced colitis, VillinCre;Dclk1f/f mice demonstrated exacerbated injury including higher clinical colitis scores, increased epithelial barrier permeability, higher levels of pro-inflammatory cytokines and chemokines, decreased levels of Lgr5, and dysregulated Wnt/b-Catenin pathway genes. These results suggest that Dclk1 plays an important role in regulating colonic inflammatory response and colonic epithelial integrity.
ABSTRACT
Oral lichenoid reactions represent a common end point in response to extrinsic agents (drugs, allergens), altered self‐antigens, or superantigens. Oral lichen planus, a common and ...under‐recognized inflammatory disorder, shares many clinical and histopathological features with oral lichenoid drug reaction and oral lichenoid contact reaction. Clinical presentation can vary from asymptomatic white reticular striae to painful erythema and erosions. Cutaneous and additional mucosal involvement is common. Delay in diagnosis of extraoral mucocutaneous lichen planus (LP) results in conjunctival scarring; vaginal stenosis; vulvar destruction; and stricture of the esophagus, urethra, and external auditory meatus. Although the etiology of LP is idiopathic, oral lichenoid reactions may be caused by medications or exogenous agents such as cinnamates and other flavorings. The clinical features, evaluation, and management of these oral lichenoid reactions are discussed.
Objectives
Many studies have reported that olfactory dysfunction frequently occurs in chronic rhinosinusitis (CRS) populations; however, the prevalence and degree of olfactory loss has not been ...systematically studied. The aims of this study were to use combined data to report the prevalence of olfactory dysfunction and to calculate weighted averages of olfactory test scores in CRS patients.
Data Sources
A search was conducted in PubMed and Scopus, following the methods of Preferred Reporting Items for Systematic Review and Meta‐Analysis guidelines.
Review Methods
Studies reporting the prevalence of olfactory dysfunction using objective measures or olfactory test scores using validated scales were included.
Results
A total of 47 articles were included in a systematic review and 35 in the pooled data analysis. The prevalence of olfactory dysfunction in chronic rhinosinusitis was found to be 30.0% using the Brief Smell Identification Test, 67.0% using the 40‐item Smell Identification Test, and 78.2% using the total Sniffin' Sticks score. Weighted averages ± standard deviation of olfactory test scores were 25.96 ± 7.11 using the 40‐item Smell Identification Test, 8.60 ± 2.81 using the Brief Smell Identification Test, 21.96 ± 8.88 using total Sniffin' Sticks score, 5.65 ± 1.51 using Sniffin' Sticks–Threshold, 9.21 ± 4.63 using Sniffin' Sticks–Discrimination, 9.47 ± 3.92 using Sniffin' Sticks–Identification, and 8.90 ± 5.14 using the Questionnaire for Olfactory Disorders–Negative Statements.
Conclusions
In CRS populations, a significant percentage of patients experience olfactory dysfunction, and mean olfactory scores are within the dysosmic range.
