Assessment of CC may vary considerably among medical specialists. Objectives: The aim was to evaluate similarities and consistency of responses across different specialists when performing a basic assessment of CC patients in primary care, and referring patients based on clinical findings or test results. Methods: A modified Delphi approach was used. A survey with 74 statements on initial assessment of CC and referral pathways was addressed to a panel of different specialists, who voted the statements in two rounds. Results: Seventy-seven physicians [18 primary care physicians (PCPs), 24 pulmonologists, 22 allergists, and 13 ear, nose, and throat specialists] from the National Healthcare System of Spain answered the questionnaire. After two rounds, the panel reached a consensus on 63 out of the 74 proposed items (85.1%). Consensus was not reached among the panelists of at ...

We aimed to generate expert consensus-based recommendations for the management of UAD patients. Methods Using a two-round Delphi method, Spanish expert allergists, pulmonologists and otolaryngologists expressed their agreement on 32 statements (52 items) on a 9-point Likert scale, classified as appropriate (median 7–9), uncertain (4–6) or inappropriate (1–3). Consensus was considered when at least two-thirds of the panel scored within the range containing the median. Results A panel of 30 experts reached consensus on the appropriateness of 43 out of the 52 (82.7%) items. The usefulness of certain biomarkers (tissue and peripheral blood eosinophil count, serum total IgE, and fraction of exhaled nitric oxide [FeNO]) in the identification and fol...

This response is caused by dysregulation of the autonomic nervous system at various levels of the nasal autonomic reflex arc. Various stimuli (methacholine, histamine, adenosine 5'-monophosphate, cold air, mannitol, rapsaicin, phentolamine, and distilled water) have been used in an attempt to find the test that most reliably differentiates between healthy individuals and patients and also between different types of rhinitis. Despite the small number of publications available, in the present review, we provide an update on current nonspecific nasal provocation techniques. The studies published to date are not comparable: the stimuli applied act through different mechanisms and are used to assess different pathways, and the methodologies differ in terms of selection of participants, concentrations used, and assessment of response (criteria for positivity). Given the limit...

Many grafts and flaps from the endonasal fossa have been demonstrated to be useful in the control of complications such a cerebrospinal fluid leaks. Review and analysis of these resources are necessary in skull base recontruction to improve outcomes. The target is to create a consensus document on the use of different endonasal flaps and grafts in the skull base surgery. Literature review of the most relevant free grafts and vascularized flaps from the endonasal fossa. Analysis using the Delphi method on the use of the different endonasal resources for endoscopic repair of skull base defects. We obtained two results: 1) A selection of the most representative flaps and grafts from the endonasal fossa, describing origin, surface and indications, based on a literature review. 2) A consensus document, using Delphi methodology, with general considerations (2), recommendations (10) and limitations (6) of the different endonasal flaps and grafts. We present the first consensus document in the field of extended endonasal endoscopic surgery using the Delphi method as a working tool. We highlight the usefulness of the nasoseptal flap together with other endonasal flaps and grafts for skull base reconstruction.

Methods: 102 out of 421 (24.2%) mildly symptomatic COVID-19 patients completed a second questionnaire about the evolution of their symptoms one year after the infection using visual analog scales (VAS). A subgroup of 69 patients also underwent psychophysical evaluation of olfactory function through UPSIT. Results: The prevalence of chemosensory dysfunction decreased from 82.4% to 45.1% after 12 months, with 46.1% of patients reporting a complete recovery. Patients older than 40 years (OR = 0.20; 95% CI: [0.07, 0.56]) and with a duration of loss of smell longer than four weeks saw a lower odds ratio for recovery (OR = 0.27; 95% CI: [0.10, 0.76]). In addition, 28 patients (35.9%) reported suffering from parosmia, which was associated with moderate to severe taste dysfunction at the basel...

Although a number of studies have described AR, no studies compared children and adult AR populations. The objective was to compare the AR characteristics between two AR cohorts of children and adults. Methods: Two AR cohorts (children and adults) from Spain were studied through observational cross-sectional multicentre studies. AR was classified based on classical (allergen exposure), original (o-ARIA), and modified (m-ARIA) ARIA criteria. AR was evaluated by Total 4-Symptoms Score (T4SS), and disease severity by Visual Analogue Scale (VAS, 0-100 mm). AR comorbidities were also evaluated. Results: A total of 5,405 patients (1,275 children, 4,130 adults) were studied. According to symptom’s duration, intermittent AR was more frequent in children than in adults. Using o-ARIA severity, more children than adults had moderate/severe AR while, using m-ARIA, more children than adults had severe AR. T4SS was higher...

In 40 cases an impacted foreign body was found. The most frequent location was the upper third of the esophagus (33/82,5%). The most common type of foreign body was chicken bones in adults (17/42) and coins in children (2/4). Nine patients (all adults) had complications.Conclusions Due to its low cost and morbility, flexible endoscopy is the first choice for managing esophageal foreign bodies. Rigid esophagoscopy is still an appropriate technique when flexible endoscopy fails or it is not possible.

Research paper thumbnail of A new criterion by which to discriminate between patients with moderate allergic rhinitis and patients with severe allergic rhinitis based on the Allergic Rhinitis and its Impact on Asthma severity items

The high prevalence of moderate/severe patients suggests the need to differentiate between them. To identify the categorization that maximizes discrimination between moderate and severe allergic rhinitis (AR) by using ARIA guidelines. Observational, cross-sectional study. Clinical characteristics, nasal symptoms (Total Symptom Score 4), and health-related quality of life (HRQL; Rhinoconjunctivitis Quality of Life Questionnaire and Short Form 12) were assessed. The association of severity items (sleep, daily activities/sport, work/school, and troublesome symptoms) with symptoms and HRQL was analyzed using linear regression models. ANOVA and effect sizes were used to assess differences in symptoms and HRQL among groups defined by the number of affected ARIA items. Nontreated patients (N = 141) with moderate/severe AR were studied. All severity items showed a similar independent association with symptoms and HRQL scores, and there were no interaction effects, indicating that categorization of patients into moderate and severe could be based only on the number of items affected. Effect sizes were highest between patients with 4 affected ARIA items and those with 3, 2, or 1 affected item (effect sizes greater than 0.8 in all comparisons using Rhinoconjunctivitis Quality of Life Questionnaire and Short Form 12 Physical Composite Summary, and greater than 0.5 using the Total Symptom Score 4; P < .001). Using ARIA severity items, the criterion that best discriminates AR severity is considering moderate those with 1 to 3 affected items and severe those with 4. Discrimination between patients with moderate and severe AR should help to obtain homogeneous populations for both research and clinical purposes.

The adverse effects of antihistamines upon the central nervous system (CNS) depend upon their capacity to cross the blood-brain barrier (BBB) and bind to the central H1 receptors (RH1). This in turn depends on the lipophilicity of the drug molecule, its molecular weight (MW), and affinity for P-glycoprotein (P-gp) (CNS xenobiotic substances extractor protein). First generation antihistamines show scant affinity for P-gp, unlike the second generation molecules which are regarded as P-gp substrates. Histamine in the brain is implicated in many functions (waking-sleep cycle, attention, memory and learning, and the regulation of appetite), with numerous and complex interactions with different types of receptors in different brain areas. Bilastine is a new H1 antihistamine that proves to be effective in treating allergic rhinoconju...
