RESUMO
Objectives@#. In this study, we evaluated the associations between birth-related exposures, postnatal factors, and the risk of allergic rhinitis and asthma in children and adolescents. @*Methods@#. We performed a comprehensive search of five literature databases up to May 2023. To quantify the associations of birth-related exposures (birth weight, delivery mode, prematurity, sex, maternal age, and parental allergy history) and postnatal factors (birth order, number of siblings, breastfeeding exclusivity, and breastfeeding duration) with allergic disease, we calculated pooled odds ratios and 95% confidence intervals. We conducted subgroup analyses for allergic disease type, birth order, number of siblings, and parental allergy history. The methodological quality of the identified studies was evaluated using the Newcastle-Ottawa Scale. @*Results@#. This meta-analysis included 31 studies, encompassing 218,899 patients in total. The birth-related exposures of low birth weight, maternal age, and prematurity (less than 37 weeks gestation) were not significantly associated with the risk of asthma or allergic rhinitis during childhood or adolescence. Male sex, family history of allergy, and cesarean delivery were linked to an elevated risk of asthma or allergic rhinitis. Among postnatal factors, exclusive breastfeeding, breastfeeding for longer than 6 months, second or later birth order, and having siblings exhibited protective effects against allergic diseases in offspring. @*Conclusion@#. The risks of allergic rhinitis and asthma were elevated in male patients, those delivered by cesarean section, and those with a family history of allergy. Conversely, exclusive breastfeeding, breastfeeding for longer than 6 months, and having siblings corresponded to a reduced risk of respiratory allergic diseases.
RESUMO
Objectives@#. Multiple minimally invasive techniques for chronic rhinitis treatment focus on posterior nasal nerve ablation. We conducted a systematic review and meta-analysis to evaluate the efficacy of cryotherapy and radiofrequency ablation for alleviating symptoms in patients with allergic and nonallergic rhinitis. @*Methods@#. We retrieved studies from PubMed, Scopus, Embase, Web of Science, and Cochrane Database up to July 2023. Data on the impact of cryotherapy and radiofrequency ablation on quality of life and symptom ratings of rhinitis were extracted and evaluated. @*Results@#. An analysis of 12 studies involving 788 patients demonstrated significant improvements in quality of life and rhinitis-related symptoms (nasal obstruction, itching, rhinorrhea, and sneezing) in patients treated with cryotherapy or radiofrequency ablation (symptom score at 24 months and quality of life score at 3 months). However, radiofrequency ablation had a more positive effect on nasal symptoms after 3 months than cryotherapy. Nonallergic rhinitis patients responded more favorably to posterior nerve ablation than patients with allergic rhinitis. Both techniques enhanced disease-specific quality of life during the initial 3 months of treatment (cryotherapy, 84.6%; radiofrequency, 81.6%; P=0.564). After 3 months of treatment, a clinical improvement in all nasal symptoms (minimal clinically important difference in the total nasal symptom score: >1.0 points) was seen in 81.8% and 91.9% of patients who underwent cryotherapy and radiofrequency ablation, respectively (P=0.005), suggesting that radiofrequency is more likely to lead to clinical improvement. @*Conclusion@#. Rhinitis-associated subjective symptom scores and quality of life may be improved by both cryotherapy and radiofrequency ablation. Ablation was more efficacious than cryotherapy for nasal symptoms in patients with nonallergic rhinitis. To corroborate these findings, further randomized controlled studies directly comparing these two techniques are warranted.
RESUMO
Microfluidic systems can be used to control picoliter to microliter volumes in ways not possible with other methods of fluid handling. In recent years, the field of microfluidics has grown rapidly, with microfluidic devices offering possibilities to impact biology and medicine. Microfluidic devices populated with human cells have the potential to mimic the physiological functions of tissues and organs in a three-dimensional microenvironment and enable the study of mechanisms of human diseases, drug discovery and the practice of personalized medicine. In the field of otorhinolaryngology, various types of microfluidic systems have already been introduced to study organ physiology, diagnose diseases, and evaluate therapeutic efficacy. Therefore, microfluidic technologies can be implemented at all levels of otorhinolaryngology. This review is intended to promote understanding of microfluidic properties and introduce the recent literature on application of microfluidic-related devices in the field of otorhinolaryngology.
RESUMO
Objectives@#. This study evaluated the diagnostic value of various symptoms of coronavirus disease 2019 (COVID-19) in screening for this disease. @*Methods@#. Two authors (working independently) comprehensively reviewed six databases (PubMed, Cochrane Database, Embase, Web of Science, Scopus, and Google Scholar) from their dates of inception until November 2020. The predictive value of patient-reported symptoms, including otolaryngologic and general symptoms, was evaluated in adults who underwent testing for COVID-19. True-positive, true-negative, false-positive, and false-negative data were extracted from each study. The methodological quality of the included studies was evaluated using the quality assessment of diagnostic accuracy studies tool (ver. 2). @*Results@#. Twenty-eight prospective and retrospective studies were included in the meta-analysis. The diagnostic odds ratio (DOR) of a change in olfaction and/or taste was 10.20 (95% confidence interval [CI], 8.43–12.34). The area under the summary receiver operating characteristic curve was 0.8. Olfactory and/or taste changes had a low sensitivity (0.57; 95% CI, 0.47–0.66) but moderate negative (0.78; 95% CI, 0.69–0.85] and positive (0.78; 95% CI, 0.66–0.87) predictive values and a high specificity (0.91; 95% CI, 0.83–0.96). Olfactory and/or taste changes had a higher diagnostic value than the other otolaryngologic symptoms, a higher DOR and specificity, and a similar or higher diagnostic value than the other general symptoms. @*Conclusion@#. Among otolaryngologic symptoms, olfactory and/or taste dysfunction was the most closely associated with COVID-19 and its general symptoms, and should therefore be considered when screening for the disease.
