Cases Of Allergic Rhinitis Research Articles

Integrated analysis of remote sensing with meteorological and health data for allergic rhinitis forecasting in Tianjin.

Long time series of vegetation monitoring can be carried out by remote sensing data, the level of urban greening is objectively described, and the spatial characteristics of plant pollen are indirectly understood. Pollen is the main allergen in patients with seasonal allergic rhinitis. Meteorological factors affect the release and diffusion of pollen. Therefore, studying of the complex relationship between meteorological factors and allergic rhinitis is essential for effective prevention and treatment of the disease. In this study, we leverage remote sensing data for a comprehensive decade-long analysis of urban greening in Tianjin, which exhibits an annual increase in vegetative cover of 0.51 per annum, focusing on its impact on allergic rhinitis through changes in pollen distribution. Utilizing high-resolution imagery, we quantify changes in urban Fractional Vegetation Coverage (FVC) and its correlation with pollen types and allergic rhinitis cases. Our analysis reveals a significant correlation between FVC trends and pollen concentrations, with a surprising value of 0.71, highlighting the influence of urban greenery on allergenic pollen levels. We establish a robust connection between the seasonal patterns of pollen outbreaks and allergic rhinitis consultations, with a noticeable increase in consultations during high pollen seasons. our findings indicate a higher allergenic potential of herbaceous compared to woody vegetation. This nuanced understanding underscores the importance of pollen sensitivity, alongside concentration, in driving allergic rhinitis incidents. Utilizing a Generalized Linear Model, significant features influencing the number of visits for allergic rhinitis (P < 0.05) were identified. Both GLM and LSTM models were employed to forecast the visitation volumes for rhinitis during the spring and summer-autumn of 2022. Upon validation, it was found that the R² values between the simulated and actual values for both GLM and LSTM models surpassed the 95% confidence threshold. Moreover, the R² values for the summer-autumn seasons (GLM: 0.56, LSTM: 0.72) were higher than those for spring (GLM: 0.22, LSTM: 0.47). Comparing the errors between the simulated and actual values of GLM and LSTM models, LSTM exhibited higher simulation precision in both spring and summer-autumn seasons, demonstrating superior simulation performance. Overall, our study pioneers the integration of remote sensing with meteorological and health data for allergic rhinitis forecasting. This integrative approach provides valuable insights for public health planning, particularly in urban settings, and lays the groundwork for advanced, location-specific allergenic pollen forecasting and mitigation strategies.

An Inflammatory Question? Prenatal Air Pollution, Childhood Allergic Rhinitis, and Healthy Fats.

A study of more than 650 toddlers found that two polyunsaturated fatty acids were associated with fewer cases of allergic rhinitis (hay fever) in children who had been exposed prenatally to higher levels of PM2.5.

Обоснование необходимости профилактики аллергического ринита на территории Воронежской области

The allergic diseases, the major role in etiology of which is played by allergens present in ambient air, are common. To develop practical guidelines on prevention of allergic rhinitis as the most prevalent disorder in the structure of allergy, it is necessary to estimate all the conditions, both negatively and positively affecting this disorder. The study was aimed to assess factors affecting the incidence, detection, and registration of cases of allergic rhinitis in the Voronezh Region. The report forms № 12 and № 30 provided substantive inputs to the study, along with the laboratory test data provided by private clinics and the social and hygienic monitoring data. Epidemiological analysis was performed by retrospective method; the territories were ranked by various indicators; the correlation analysis method was applied. We determined the incidence rates and the districts at high risk of allergic rhinitis (pollinosis) in all population groups for the period 2012–2021. We determined the structure of aeroallergens identified in private healthcare institutions, assessed the staffing levels of allergists in the public institutions of the Voronezh Region, and identified significant environmental factors. The identified features of the prevalence, diagnosis, and registration of allergic rhinitis in the Voronezh Region can be used to improve preventive measures targeting this allergic disorder.

Predictive Value of Fractional Exhaled Nitric Oxide (FeNO) in the Diagnosis of Asthma for Epidemiological Purposes-An 8-Year Follow-Up Study.

The follow-up included 128 (out of 447) children, 70 girls and 58 boys. The FeNO was measured at baseline only. The prevalence of asthma-like symptoms was measured with the adopted version of the ISAAC questionnaire. After 8 years of FeNO measurement, 5 new cases of asthma, 2 cases of attacks of dyspnoea, 1 case of wheezy in the chest, and 18 cases of allergic rhinitis occurred. The FeNO values, measured at the baseline of the study, for new cases of the above diseases were 53.4 ± 75.9 ppb, 11 ± 1.5 ppb, 12.0 ppb, and 16.3 ± 12.4 ppb, respectively. The best diagnostic accuracy parameters were found in the new cases of asthma, where the sensitivity was 40.0%, the specificity was 98.6%, and the AUC was 66.6%. The diagnostic odds ratio was 46.9 when considering the FeNO cut-off >35 ppb. The FeNO measurement is a fair method for asthma prognosis in early school-aged children with asthma-like symptoms measured on the population level but requires further confirmation at the clinical level with more accurate diagnostic tools.

Local allergic rhinitis: considerations.

The term "local allergic rhinitis" has gained popularity as a clinical entity in recent years. Despite the apparent contradiction in the definitions of "nasal" and "local," we offer insights based on our extensive experience in the field. Local allergic rhinitis has been recognized and treated for many years, so it is not a new discovery. The nasal provocation test, which was introduced in the 1980s, was critical in identifying allergic rhinitis cases with suggestive symptoms but negative allergy tests. Our reflections aim to contribute to a precise terminological decision that is consistent with various points of view.

Molecular sensitization patterns to cat and dog allergens in Lithuanian children population

BackgroundOver the last few decades, there was observed an increase of asthma and allergic rhinitis cases caused by allergy to pets. ObjectiveThis study aimed to analyze molecular sensitization patterns to dog and cat allergens in Lithuanian children who were experiencing allergy-like symptoms. Materials and methodsA total of 574 children (0–18 years) were tested for allergen-specific immunoglobulin E (sIgE) levels with ALEX2 (ALEX2®, Allergy Explorer Test System). Positive sera were further analyzed for sensitization to cat (Fel d 1, Fel d 2, Fel d 4, and Fel d 7) and dog (Can f 1, Can f 2, Can f 3, Can f 4, Can f 5, and Can f 6) allergen components. ResultsTwo hundred forty-seven children tested positive (sIgE ≥0.3 kUA/L) to at least 1 dog or cat allergen component. There were 61.1% children sensitized to components from both sources, 29.2% – exclusively to cat, and 9.7% – to dog components. The major sensitizers were Fel d 1 (84.8%) and Can f 1 (59.4%). There were 42.9% patients sensitized to 3 or more different mammalian protein families and 40.4% – to 3 or more lipocalins. There were 5.7% of children sensitized both to Fel d 1 + Fel d 4 and Can f 1/2 + Can f 5, indicating the high risk of severe asthma. Monosensitization to Fel d 1 was the dominant pattern among Lithuanian children (26.3%). ConclusionThe majority of children were cat/dog-polysensitized, although sensitization only to cat allergens was most observed. Extensive molecular profiling can be an useful tool for accurate true sensitization diagnosis and prognosis of disease severity.

What's childhood asthma in French Guiana? A cohort study based on children referred for allergology consultations at the Cayenne hospital center.

Asthma is a multifactorial chronic disease, whose most frequent etiology is allergy, especially to Blomia tropicalis. In French Guiana, the childhood prevalence of Blomia T sensitization is unkwown. The aim of this study was to determine the proportion of sensitization to Blomia T and other mites in asthmatic children, and to describe the characteristics of childhood asthma in French Guiana. A retrospective cohort study focused on children from 0 to 18 years of age, followed for asthma at the Department of Pediatrics of the Cayenne Hospital Center in French Guiana. All asthmatic children followed by the same paediatric allergist were systematically skin-tested with Bt total extract, and Bt-specific IgE tests were additionally performed to confirm specific sensitization. All follow-up variables were collected from medical records. The outcome was sensitization to Blomia tropicalis and other allergens, and the explanatory variables were those of asthma follow-up. Patients were categorized into Blomia tropicalis sensitization yes/no. Logistic regression analysis was used to assess the relationship between follow-up variables and the outcome. 302 patients were followed: 177 cases of allergic rhinitis, 135 allergic conjunctivitis, 105 atopic dermatitis, 153 food allergy, and 14 cases of drug allergy. Poly-allergy (respiratory, food, skin, and medicinal) was present in 239 children. There were 158 children followed for asthma, of whom 103 (65%) were sensitized to Blomia tropicalis. The median age of the asthmatic children sensitized to Blomia tropicalis was 7 years, and 3 years for those who were not sensitized (p < 0.001). Among the girls (n = 58), 67% were sensitized to Blomia; 97 (92%) asthmatic children co-sensitized to Blomia tropicalis, Dermatophagoides pteronyssinus, and Dermatophagoides farinae. Multivariate analysis showed that the childhood asthma in French Guiana is characterized by a median age of 7 years (p < 0.001), a high prevalence of Blomia tropicalis (p < 0.001), co-sensitization to other mites (p < 0.001), and a high prevalence of co-sensitization to cockroaches (p = 0.006). The area under the ROC curve was close to 0.9, confirming the quality of our model. In French Guiana, asthma is characterized by a high prevalence of Blomia tropicalis sensitization.

Surgical treatment of vidianneurectomy and selective vidianneurectomy in 60 cases of refractory allergic rhinitis

Objective: To explore the effect of vidian neurectomy and selective vidian neurectomy in the treatment of moderate and severe persistent allergic rhinitis (AR). Methods: A total of 60 patients with moderate-to-severe persistent AR treated in Zhejiang Provincial Hospital of Integrated Traditional Chinese and Western Medicine from June 2018 to June 2020 were selected, including 28 males and 32 females. A total of 40 cases in the observation group were subjected to vidianneurectomy, while, 20 cases in the control group underwent selective vidianneurectomy. Patients in the two groups were followed up at 6 months, 1 year, and 2 years, respectively, and evaluated according to AR diagnostic and efficacy assessment criteria. Four symptoms of sneezing, clear runny nose, nasal congestion, and nasal itching were scored as efficacy indices before and at 6 months, 1 year, and 2 years after surgery. The regression of the lower turbinate swelling after surgery was assessed by nasal endoscopy or sinus CT. Postoperative tear secretion was followed up in both groups, and patients with dry eyes were counted in combination with ocular symptoms. SPSS 19.0 software was used to statistically analyze the data before and after the surgery and between the two groups. Results: The preoperative, 6-month, 1-year, and 2-year postoperative inferior turbinate signs were (2.73±0.45), (1.20±0.41), (1.25±0.49) and (1.30±0.56) points in the observation group and (2.75±0.44), (1.45±0.69), (1.75±0.72) and (1.90±0.85) points in the control group, respectively, with a statistically significant difference in the between-subjects effect test between the two groups (F=8.28, P<0.05), indicating a more durable surgical effect in the observation group. The total effective rate at 2 years after surgery was 95.0% (38/40) in the observation group and 50% (10/20) in the control group. The difference between the two groups by Fisher's exact test was statistically significant. No dry eye patient was found in either group at a 1.5-year postoperative follow-up. Conclusion: Both vidianneurectomy and selective vidianneurectomy have good recent treatment effects, vidianneurectomy has better long-term curative effects than selective vidianneurectomy.

Is Allergic Rhinitis Associated With Enuresis Nocturna In Childhood ?

Introduction&#x0D; Allergic rhinitis is the most common form of non-infectious rhinitis and is manifested with the symptoms of nasal congestion, sneezing, nasal discharge, and itching. Primary enuresis nocturna is involuntary urination while asleep after five years, at which bladder control usually begins. Our objective was to evaluate the relationship between allergic rhinitis and primary enuresis nocturna in childhood in this research.&#x0D; Methods:&#x0D; We included 300 children with allergic rhinitis and 300 control cases between the age of 5 and 17 years. With allergic rhinitis cases, age, gender, body mass index percentile, other allergic disorders, allergic rhinitis diagnosis age, allergic rhinitis severity and distribution, presence of primary enuresis nocturna, and presence of primary enuresis nocturna in the family were recorded. Subjects with disorders causing enuresis were excluded from the study.&#x0D; Results:&#x0D; The mean age in the allergic rhinitis and control groups was 9,6±3,4 vs. 10,0±3,1 years, respectively (p=0,15). There was no statistical difference between the two groups in terms of gender, age, body mass index percentile, and primary enuresis nocturna presence in the family (p=0.29, p=0.15, p=0.46, p=0.17; respectively). Primary enuresis nocturna was significantly higher in allergic rhinitis cases (p=0.02). Primary enuresis nocturna was significantly higher in boys than in girls (p=0.007). There is a significant difference in age and gender between those with and without primary enuresis nocturna in allergic rhinitis groups (p=0,001, p=0.01, respectively).&#x0D; Conclusion:&#x0D; We conclude that as allergic rhinitis increases the incidence of primary enuresis nocturna and worsens the quality of life, its treatment should not be neglected.

Twenty cases of perennial and seasonal allergic rhinitis treated with LumiMed® Nasal Device

BackgroundAllergic rhinitis is the most common allergic disease, with a prevalence up to 40% in the general population. Allergic rhinitis requires daily treatment to block inflammatory mediators and suppress the inflammatory response. However, these medications may have harmful side effects. Photobiomodulation as a treatment modality to reduce inflammation has been beneficial in many chronic disorders, yet therapy has not been US Food and Drug Administration approved for the treatment of allergic rhinitis. The LumiMed Nasal Device was designed to address the limitations associated with the treatment of allergic rhinitis with photobiomodulation. This in-office study hopes to show efficacy, usability, and comfortability of the LumiMed Nasal Device.Case presentationTwenty patients with allergic rhinitis were treated during high allergy season with LumiMed Nasal Device. The average age of patients was 35 years (10–75); 11 were female and 9 were male. The population’s ethnicities were white (n = 11), Black (n = 6), Oriental (n = 2), and Iranian (n = 1). Patients were treated with twice-daily dosing, 10 seconds in each nostril, for 10 consecutive days. After 10 days, patients were evaluated for symptom relief, device comfort and device ease of use. The Total Nasal Symptom Score was used to assess severity of main symptoms of allergic rhinitis. The sum of Total Nasal Symptom Scores for each symptom category was calculated (total possible scores per patient were 0–9). Rhinorrhea/nasal secretions, nasal congestion, and nasal itching/sneezing were evaluated on a scale of 0–3 (0 no symptoms, 1 mild symptoms, 2 moderate symptoms, 3 severe symptoms). Device comfort was evaluated on a scale of 0–3 (0 no discomfort, 1 mild discomfort, 2 moderate discomfort, 3 severe discomfort). Device ease of use was evaluated on a scale of 0–3 (0 very easy, 1 somewhat difficult, 2 difficult, 3 very difficult).ConclusionsThe results from these case studies indicated that of the 20 patients in this case study, 100% of patients experienced improvement in overall Total Nasal Symptom Score after using LumiMed Nasal Device. Of those patients, 40% brought their Total Nasal Symptom Score down to 0. Furthermore, 95% felt the LumiMed Nasal Device was comfortable to use, while 85% of patients felt the LumiMed Nasal Device was easy to use.

Psoriasis associated with asthma and allergic rhinitis: a US-based cross-sectional study using the All of US Research Program.

Psoriasis is a common chronic inflammatory disease with multiple known comorbidities. Increasing evidence suggests some mechanistic overlap in the immunopathogenesis of psoriasis and some cases of asthma and allergic rhinitis (AR), but the potential association between psoriasis and asthma and AR has not been thoroughly investigated. The study aimed to investigate the association between psoriasis and asthma and AR. We used data from the NIH All of US Research Program, a nationwide longitudinal cohort of US adults, collected from 2018 to present. The source population comprised a demographically and socioeconomically diverse cohort of over 300,000 Americans. We used multivariable logistic regression models to examine the association between psoriasis and asthma and AR, after adjusting for sociodemographic variables, body mass index, and smoking status. In total, 235,551 participants (mean [SD] age, 54.7 [16.6] years; 59.3% female), including 5165 individuals with psoriasis and 230,386 individuals without psoriasis, were included in our analysis. Participants with psoriasis had significantly higher prevalence of asthma (26.1% vs. 12.9%; P < 0.001) and AR (31.8% vs. 13.4%; P < 0.001) compared to participants without psoriasis. Psoriasis was significantly associated with both asthma [adjusted odds ratio (aOR) 2.22; 95% confidence interval (CI) 2.08-2.37] and AR (aOR, 2.57; 95% CI 2.42-2.73). In subgroup analyses, associations remained stable in multivariable analyses after stratification by age, sex, and income. Psoriasis is associated with both asthma and AR in our sample of US adults. Further research is needed to explore potentially unifying inflammatory pathways among psoriasis, asthma, and AR.

Role of aralia racemosa in management of allergic rhinitis

Allergic rhinitis is a disease characterized by watery coryza, sneezing with irritation in nose, throat and eyes. Cases of allergic rhinitis is increasing globally, and it is impacting the quality of life of patient and increasing the economic burden of the country. The symptoms of allergic rhinitis though does not lead to mortality but it can cause various complications, thus these symptoms should not be neglected and proper,management should be done to prevent the complications and improve the quality of life of patients. Aralia racemosa is one of the most commonly indicated medicine for allergic rhinitis which can aid in improving the symptoms of allergic rhinitis along with asthma.

Hyper IgE syndrome with autoimmune hemolytic anemia in Saudi Arabia

Background: Hyper IgE syndrome (HIES) is a rare primary immunodeficiency disorder characterized by elevated serum immunoglobulin E (IgE) levels. Autosomal dominant and autosomal recessive forms of HIES have been reported. Autosomal recessive HIES typically includes a history of asthma, atopic dermatitis, food allergy, and recurrent viral infection. HIES diagnosis requires genetic study, which is time-consuming and not always feasible. Case Presentation: We report the case of an 8-year-old female. The patient recently presented to our emergency department with pallor and syncope. Upon examination, the hemoglobin level was 4.9 g/dl. Direct antiglobulin test showed a positive result. The patient had an admitting diagnosis of autoimmune hemolytic anemia, a rare complication of autosomal recessive HIES. The patient is a known case of asthma, herpetiformis dermatitis, nut allergy, and allergic rhinitis. HIES was the first possible diagnosis, which was further confirmed by clinical presentation and a high serum IgE count. The patient was referred to a tertiary care center for genetic counseling and further follow-up. Conclusion: HIES is a rare immune deficiency disorder that can be inherited in either an autosomal dominant or recessive pattern. Although these two types show similar clinical presentations, certain features remain distinct, providing a valuable insight into the final diagnosis even without the gene study results. To the best of our knowledge, no study has evaluated HIES in general, and no case report has evaluated autosomal recessive HIES in Saudi Arabia. This case study will guide the medical community in the early-stage diagnosis and management of HIES.

Prevalence of rhinology related consultations in an ear, nose throat clinic in a period of 1 year

&lt;div class="WordSection1"&gt;&lt;p&gt;&lt;strong&gt;Background:&lt;/strong&gt; Several studies have been conducted to forecast the top emergencies that are frequently seen among patients in an ENT clinic. In the past four years, there has been only one study that calculates the prevalence of a specific rhinology disease (allergic rhinitis) in five Middle Eastern countries. The results of the study have demonstrated that 1808 of 33,486 subjects enrolled in the study have fulfilled the case definition of allergic rhinitis. The mentioned study has only reviewed active cases of allergic rhinitis, disinclining other rhinology conditions that patients frequently complain of. The following paper will calculate the prevalence of common rhinology conditions generally in a specialized ENT clinic in the Kingdom of Bahrain over a period of 1 year.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods:&lt;/strong&gt; Patients’ information was collected prospectively on monthly basis starting from June 2021 until June 2022. The patients were registered under a senior ENT consultant at a semi-governmental hospital in The Kingdom of Bahrain.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results:&lt;/strong&gt; Out of 2711 subjects enrolled in the study, 1424 patients have been registered with rhinology related complaints, exhibiting approximately (52.4%) of the total sample size. Allergic rhinitis was the most prevalent clinically diagnosed rhinology disease and Rhinoplasty surgery was the most frequently operated surgery. The socio-demographics of the study measured (52.0%) Higher females ration between Rhinology patients. In contrast, A higher percentage of males attended the clinic for otology/ear consultations (57.2%).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions:&lt;/strong&gt; Rhinology related consultations is concluded to be more prevalent compared to otology and laryngology.&lt;/p&gt;&lt;/div&gt;

Association of birthweight with lung function and respiratory diseases: results from the GEIRD study

Abstract Background Early life conditions are associated with lung function and the development of respiratory and non-respiratory illnesses. The relationship with birthweight (BW) is however conflicting. We examined associations of BW with lung function and respiratory diseases within the GEIRD (Gene-Environment Interaction in Respiratory Diseases) study. Methods GEIRD is an Italian multi-centre, multi-case control study of people aged 20-84 from the general population conducted from 2008 to 2014. The study included cases of COPD, asthma, allergic rhinitis and controls. Multinomial logistic regression was performed with case/control status (control/COPD/asthma/allergic rhinitis) as response variable, and BW as main determinant adjusting for sex, age and smoking status. Results Of 2,287 reporting BW, 6.4 % (n = 147) had low BW (&amp;lt;2500 gr), and this proportion was greater in women than men (7.8% vs. 5.1%; p = 0.006). Lung volumes were significantly lower in individuals with low than normal BW. Median FEV1 was 3.01 L (p25-p75=2.60-3.45 L) versus 3.16 L (2.65-3.86 L) (p = 0.019) and median FVC was 3.68 L (3.19-4.34 L) versus 3.91 (3.34-4.81 L) (p = 0.003). However, FEV1 and FVC were not affected by BW when expressed as percent predicted. Of note, both men and women with low BW were shorter than those with normal BW (mean±SD: 160.2±5.5 vs. 162.6±6.5 cm in women, p = 0.009; 172.4±6.1 vs. 174.8±7.2 cm in men, p &amp;lt; 0.001). FEV1/FVC expressed as absolute ratio or as percent predicted, was not affected by BW. In multinomial analysis, BW was not associated with respiratory diseases in adulthood. However, those with low BW had a higher risk of self-reported hospitalisation for lung disease before age 2 (10.3% vs. 4.1%) and severe respiratory infection before age 5 (16.9% vs. 8.8%) (p = 0.003). Conclusions BW was not associated with lung function in adulthood, when controlling for sex and height. Low BW was a risk factor for respiratory diseases in childhood, not in adulthood. Key messages • Low birthweight was associated with respiratory diseases in childhood but not in adulthood. • Although spirometrically-assessed lung volumes were lower in adults with low birthweight, this is likely explained by associations of low birthweight with sex and height.

Prevalence of Otorhinolaryngological Manifestations of COVID-19 Infection during Third Wave and Comparison from Seasonal Flu and Allergic Rhinitis in a Tertiary Care Hospital

Background: Ever since the cluster of COVID-19 cases seen in Wuhan, China, the animal-origin virus has created havoc. These changes in clinical manifestations have been tracked in different waves, in different countries, also the virus behaving differently according to race and culture. To assess the prevalence of symptoms of COVID-19 infection during the third wave and compare it with seasonal flu and allergic rhinitis. Materials and Methods: A cross-sectional, comparative study was conducted at a tertiary hospital in Bareilly. A close-ended questionnaire was prepared to assess the otorhinolaryngological symptoms of COVID-19, seasonal flu, and allergic rhinitis. ENT findings were further confirmed by a suitable test. Results: A total of 145 tested positive for COVID-19 infection, 121 patients were diagnosed with seasonal flu, and 124 patients were diagnosed as cases of allergic rhinitis. Fever was the most common symptom in seasonal flu (100%) and COVID (93.8%) patients. Rhinorrhea (100%), lacrimation (100%), and sneezing (100%) were common symptoms in the allergic rhinitis group. A Chi-square test with Bonferroni correction showed a significant difference in the prevalence of symptoms in all three groups (P &lt; 0.0001). Vaccination also contributed to less severity of COVID-19 disease. Conclusion: Involvement of otorhinolaryngology is considered a biomarker in all three groups with less frequent pulmonary features. It becomes necessary to correctly differentiate COVID-19 from the other two diseases for the proper treatment of patients.

Trends in the Epidemiology of Allergic Diseases of the Airways in Children Growing Up in an Urban Agglomeration.

The prevalence of asthma and allergies among children has become an increasing problem in the last few decades. Data on the population of children and adolescents, especially living in polluted cities, are limited and based on studies carried out in small groups. In our study, we analyzed the incidence of asthma and allergic rhinitis between 2014 and 2018. We analyzed data collected from nearly 30,000 children aged seven to eight and adolescents aged 16–17, which allowed us to assess the frequency of allergic diseases in the population of children and youth in Krakow. More than 40% of respondents reported allergic symptoms, and nearly 50% of them were not diagnosed and treated. In the group of seven- and eight-year-olds with a positive history of allergies, 52% had allergic rhinitis and 9.1% had asthma. In the group of 16–17-year-olds, allergic rhinitis was diagnosed in 35.8%, while asthma was found in 4.9% of cases. The results obtained over the course of 10 years has shown the reduction in the frequency of asthma (from 22% in the case of asthma in both age groups) and allergic rhinitis cases (from 63.9% in adolescents). In our opinion, this can be considered a positive effect of the preventive measures taken in Kraków after 2010. Although there is still a higher incidence of allergic diseases among children and young people living in urban areas compared to rural areas, the trend apparently has reversed for some diseases.

The prevalence of asthma, allergic rhinitis, and eczema among school-aged children in Qatar: A Global Asthma Network Study.

This cross-sectional study aims to utilize the Global Asthma Network (GAN) questionnaires to estimate the prevalence of asthma, allergic rhinitis, and eczema among children in Qatar. The study population was comprised of children ages 6-7 and 13-14 years, along with their parents or guardians. The English and Arabic versions of the GAN questionnaires were used to collect data for this study. A total of 2646 participants were recruited (1210 in the 6-7 years age groupand 1436 in the 13-14 years age group), in addition to a total of 3831 parents or guardians. The overall prevalence of diagnosed asthma, lifetime allergic rhinitis, and diagnosed eczema in our study sample were as follows: 34.6%, 30.9%, and 37.4%, respectively. The current study showed an increased prevalence rate of asthma and eczema comparing to previous local estimates. These rates were higher in some cases or comparable in other cases to those found elsewhere. It is recommended that future research focus on studying the various factors contributing to the cases of asthma, allergic rhinitis, and eczema in Qatar. The reporting of this study conforms with the STROBE statement.

Pulmonary function tests in children with allergic rhinitis

Background: Allergic Rhinitis is a chronic and common respiratory disorder due to its prevalence, effect on quality of life, performance at school and work place, economic burden and link with asthma. Pulmonary function tests like FEF (25-75%) and PEFR are impaired in allergic rhinitis Expiratory air flow limitation is the hallmark of physiological change in allergic rhinitis. Aims and Objective: The present study aims to study pulmonary function tests such as FVC, FEF, (25-75%) and PEFR in allergic rhinitis cases to evaluate their predilection to the development of asthma. Materials and Methods: The study was carried out in the Department of Physiology at Index Medical College Hospital and Research Center, Indore, Madhya Pradesh. The study was done on 80 male and female subjects of the age group of 6 to 18 years. Forty male and female subjects suffering from allergic rhinitis attending the Ear, Nose and Throat outpatient department of IMCHRC, Indore were taken as cases. Forty males and females were taken as controls after careful selection as per inclusion and exclusion criteria. PFT was done by Digital Spirometer – Helios 401 manufactured by RMS India.
