Rationale: Evidence-based medicine represents the effort to highlight the best intervention for patients, clinicians, and policy makers, each from their respective viewpoint, to solve a particular health condition. According to a recently diffused grading system of evidence and recommendations for medical interventions, efficacy and safety represent 2 of the most important features to consider, and data from meta-analyses of randomized controlled clinical trials (RCTs) is the strongest supporting demonstration. Fexofenadine has been used for its efficacy and safety in the treatment of allergic rhinitis (AR) for many years although no meta-analyses supporting its use currently exist. The aim of this study is to assess for the first time the efficacy and safety of fexofenadine in the treatment of AR by means of a meta-analytic analysis of existing RCTs. Since specific evidence should be provided to address recommendations in a pediatric population, the quality of the estimates of this subgroup analysis is assessed. Methods: All double-blind, placebo-controlled randomized trials assessing the efficacy of fexofenadine in AR were searched for in OVID, Medline, and Embase databases up to December 2007. Outcomes were extracted from original articles; when this information was not available, the authors of each trial were contacted. Some graphics were digitalized. The RevMan 5 program was used to perform the analysis. GradePro 3.2.2 was used to assess the quality of the evidence for a pediatric population. Results: Of 2,152 identified articles, 20 were potentially relevant trials. Eight studies satisfied the inclusion criteria and were included in the meta-analysis. The main reasons for exclusion were: unnatural exposure, strong study limitations, an atypical outcome measurement, a design for other outcomes, and not being a placebo-controlled, single-blind study. Seven trials investigated a mixed population of adults and children, 1 trial investigated only children, and 1 trial only adults. In 1,833 patients receiving fexofenadine (1,699 placebo), a significant reduction of the daily reflective total symptom scores (TSS) (SMD –0.42; 95% CI –0.49 to –0.35, p < 0.00001) was found. Positive results were also found for morning instantaneous TSS and individual nasal symptom scores (sneezing, rhinorrhea, itching, and congestion). The safety analysis did not show a significant difference in reported adverse events (AE) between the active and placebo treatment groups (OR = 1.03; 95% CI 0.87–1.22, p = 0.75). A very low heterogeneity between the studies was detected, so a fixed-effects model was used. The mean quality level of the included trials was medium. Specific information for a pediatric population may be assumed with a moderate quality of evidence from only 1 study and with a low quality of evidence, mainly due to indirectness, from the others. Conclusions: This study has 5 major strengths: it represents the first attempt to evaluate the efficacy and safety of fexofenadine in the treatment of AR by means of a meta-analysis...
Otitis Media with Effusion (OME) is an inflammatory condition of the middle ear cleft, acute or chronic, with collection of fluid in the middle ear with an intact tympanic membrane. It is a very common disease in childhood, the most frequent cause of hearing loss in childhood and often requiring surgery. OME is called chronic when the fluid in the middle ear persists for more than three months or when the episodes recur six or more times in one year. The current article covers various aspects of OME including definition, epidemiology. Pathomechanisms, risk factors, role of allergy in OME, impact of upper airway disease on OME, eosinophilic otitis media and management of OME.
Background: On March 20 2020, the Argentine Ministry of Health enforced a mandatory quarantine throughout the country in response to the COVID-19 pandemic. Aims: The object of this study is to determine the initial impact on mental health of Argentine population, by measuring the prevalence of anxiety, depression, insomnia, and self-perceived stress and by determining the associated risk factors, and to analyze that impact in relation to the number of confirmed cases and deaths. Method: A cross-sectional survey was conducted through a digital questionnaire, which was completed by 1,985 respondents between March 29 and April 12. The prevalence of anxiety, depression, stress and insomnia was measured with the Generalized Anxiety Disorder-7 Scale (GAD-7), the 9-Item Patients Health Questionnaire (PHQ-9); the Perceived Stress Scale (PSS-10) and the Pittsburgh Sleep Quality Index (PSQI), respectively. Results: The 62.4% of the surveyed population reported signs of psychological distress. It was found that being a woman, being 18 to 27 years old, living with family members or a partner, smoking, and having a poor sleep quality were the significant risk factors. Conclusion: Despite the low number of COVID-19 confirmed cases and deaths at that time, a strong impact on mental health indicators was revealed. The authors of this study recommend the monitoring of the population at risk over time and early interventions in order to avoid long-lasting mental health problems.
Childhood asthma is a widespread health problem because of its epidemic prevalence, as asthma affects more than 300 million people worldwide. Results from cross-sectional and cohort studies show that asthma starts in childhood in a large proportion of cases. A proper diagnosis is easier to make in adults and school-age children, as permanent changes in lung development, the strong impact of environmental factors on the airways, the immunologic maturity process, and the use of some diagnostic tools make asthma more difficult to diagnose in preschool children. This period of a child's life is an interesting challenge for pediatricians and specialists. The aim of the present review is to analyze the current knowledge regarding making an early and accurate asthma diagnosis and therefore deciding on the correct treatment to gain control over asthma symptoms and minimize health risks.
Latin-American children with asthma and/or allergic rhinitis showed sleep disorders identified by the CSHQ when compared to normal controls. Despite being treated, asthma causes sleep impairment, especially when uncontrolled.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
