Self-effectiveness and healthy lifestyle behaviors in adolescents with asthma.

OBJECTIVES: The aim of this study was to examine the self-efficacy and healthy lifestyle behavior levels in adolescents with asthma. MATERIALS AND METHODS: Socio-demographic questionnaire form, questions about adherence to asthma medication, asthma control test, healthy lifestyle behaviors scale, and self-efficacy scale for children and adolescents with asthma were administered to 150 patients whom age range between 12-18, in follow up with asthma in the pediatric allergy outpatient clinic. RESULTS: There was no statistically significant relationship between healthy lifestyle behaviors scale and self-efficacy scale scores between adolescents with controlled and uncontrolled asthma. When patients were grouped regarding the treatment compliance, both healthy lifestyle behaviors scale and asthma self-efficacy scale scores were found to be higher in patients with treatment compliance. When the patients were grouped on the basis of gender, regular follow-up visits, and smoking, there was no significant difference between healthy lifestyle behaviors and self-efficacy scale scores. CONCLUSIONS: The findings showed us the importance of the relationship between healthy living and adolescent self-efficacy in adherence to treatment, while there are many more components in asthma control.

Monetary values of increasing life expectancy: Sensitivity to shifts of the survival curve.

Individuals' monetary values of decreases in mortality risk depend on the magnitude and timing of the risk reduction. We elicited stated preferences among three time paths of risk reduction yielding the same increase in life expectancy (decreasing risk for the next decade, subtracting a constant from or multiplying risk by a constant in all future years) and willingness to pay (WTP) for risk reductions differing in timing and life-expectancy gain. Respondents exhibited heterogeneous preferences over the alternative time paths, with almost 90 percent reporting transitive orderings. WTP is statistically significantly associated with life-expectancy gain (between about 7 and 28 days) and with respondents' stated preferences over the alternative time paths. Estimated value per statistical life year (VSLY) can differ by time path and averages about $500,000, roughly consistent with conventional estimates obtained by dividing estimated value per statistical life by discounted life expectancy.

Evaluation of the Impact of Environmental Changes on Asthma Control in Children, Access to Health Care, and Treatment Adherence in Early COVID-19 Lockdown.

OBJECTIVE: During the coronavirus disease 2019 pandemic, lockdown measures and difficulties in accessing healthcare have impacted asthma management in children. This study aimed to determine the evaluation of the impact of environmental changes on asthma control in children, access to health care, and treatment adherence in early coronavirus disease 2019 lockdown. MATERIALS AND METHODS: The study included children with asthma aged 6-11 years. A survey form was administered to the patients who visited the pediatric allergy outpatient clinic between June 1 and 30, 2020. The survey acquired demographic information about the children and their families as well as information about their asthma symptoms, how they reached healthcare services, and adherence. The childhood asthma control test was administered. The P values <.05 were considered significant. RESULTS: The study included a total of 123 children (female/male : 48/75) with a mean age of 8.4 ± 1.9 years. According to the mothers' self-report, it was found that 78% of the patients were not able to follow-up routinely, 19.5% were non-adherence to treatment, and 16.2% were poorly controlled asthma. It was found that, based on childhood asthma control test scores, asthma control was better during the pandemic lockdown period (P = .001). Asthma symptoms were better in 41.5% of the patients compared to the previous months and in 53.7% compared to the same period last year. CONCLUSION: Our study found that the children's asthma was controlled although most of them did not have their follow-up visits, and poorly controlled asthma was higher in older children in early coronavirus disease 2019 lockdown.

Anxiety Levels and Changes in Health and Hygiene Behaviors in Mothers of Children with Asthma in Early COVID-19 Lockdown in Turkey.

Objective: The restrictions imposed by the coronavirus disease 2019 (COVID-19) pandemic have caused significant changes in people's lives. This study aimed to investigate anxiety levels and changes in health and hygiene behaviors in mothers of children with asthma in early COVID-19 lockdown in Turkey. Materials and Methods: This study was a cross-sectional survey conducted on children with asthma, 6 to 11 years of age, between June 1 and 30, 2020, in Turkey. A sociodemographic data form, health and hygiene behavior form, childhood asthma control test, and state-trait anxiety inventory were administered to the mothers of the children. Results: The asthma group included 123 children (Female: 39.0%) and median age, interquartile range (IQR) [minimum-maximum]: 8.0 (6) [6-12] years; the control group included 88 children (Female: 47.7%) median age, IQR [minimum-maximum]: 8.0 (7) [5-12] years. Increased hygiene behaviors and high compliance with social isolation measures were recorded in the early lockdown, with no difference between the groups. Before the pandemic, the most frequently used cleaning products were general-purpose cleaners. During the early lockdown, however, the most frequently used product was disinfectants and was similar in both groups. In both groups, the rate of using nutritional supplements increased during the pandemic period, but the rate was higher in children with asthma both before and during the early lockdown (P < 0.001). The anxiety levels of the mothers in asthma and control groups were similar. Conclusion: This study is the first in Turkey demonstrating that, in mothers of children with asthma, lifestyle changes related to health and hygiene and anxiety levels are similar to those of other children and their mothers during the early lockdown period of COVID-19 pandemic.

An evaluation of the factors affecting the clinical and laboratory findings, prognosis, and treatment response in children with chronic urticaria.

Chronic urticaria (CU) is a rare disease in childhood, and studies in children are limited. In this study, the aim was to investigate the clinical and laboratory findings and demographic characteristics of children with CU and to determine the factors affecting prognosis. The study included 141 patients aged 0-18 years who were diagnosed with CU in the pediatric allergy outpatient clinic between January 1, 2013, and December 31, 2018. Risk factors related to prognosis were investigated by comparing the duration of CU and treatment response with clinical and etiological features. IBM SPSS version 24 was used for statistical analyses. In the study group, the female/male ratio was 69/55, and the median age at first visit was 9.5 years (min:1, max:17). Among patients, 63 (44.5%) had an accompanying atopic disease, and 23 (16.3%) had chronic disease. Of the patients, 124 (88%) had chronic spontaneous urticaria, and 17 patients (12%) had chronic inducible urticaria (CIU). Of those with CIU, 72.2% had symptomatic dermographism, 16.7% had cholinergic urticaria, and 11.1% had cold urticaria. After the evaluations, the most common pathological findings in our patients were intestinal parasitosis (n = 14), anemia (n = 10), and urinary tract infection (n = 8). The median total duration of urticaria was 47 weeks (min:8, max:284). The duration of urticaria was longer in patients with atopy (p < 0.05), and the group that went into remission with standard-dose antihistamine was the group with highest eosinophil count (p = 0.022). In most children with CU, the underlying cause/disease cannot be determined. In our study, treatable triggers were found in some of the patients. Therefore, it is appropriate for each patient to be evaluated with selected laboratory tests after detailed history and physical examination.

Comparison of diagnostic tests for suspected cow's milk allergy in children with atopic dermatitis.

BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease. A third of pediatric AD patients have also food allergy. Although food challenge test is gold standard test for the diagnosis of food allergies, they should be administered by experienced physicians, considering that the test is time-consuming and carries some risks. Documentation of the efficacies of specific IgE (sIgE), skin prick test (SPT), and atopy patch test (APT) are important for determining the necessity of oral food challenge tests(OFC). METHODS: Fifty-three AD patients with suspected cow's milk allergy (CMA) were included in our study. Diet-related questions were asked to the patients. Blood samples were taken for measurement of total blood count, total IgE, and milk sIgE. OFC, SPT, and APT were performed using pasteurized cow milk. RESULTS: The mean age of the study population was 1.4±0.8 years, and the male:female ratio was 1.12. Cow milk allergy was detected in 45.3% of the patients after OFC. A comparison between CMA(+) and CMA(-) patients revealed no significant difference in sIgE positivity (P=0.940), but there was a significant difference in SPT (P=0.000) and APT (P=0.001) positivity. When our study group was divided into immediate reaction, delayed onset reaction, and not reactive subgroups after OFC, efficacy of SPT was more prominent in immediate reaction subgroup while APT was more efficient in delayed reaction subgroup. CONCLUSIONS: Our study showed that using SPT test with APT test in allergic reactions with IgE and other mechanisms such as AD will increase the diagnostic yield, thereby reducing the need for OFC.

Food-induced anaphylaxis in early childhood and factors associated with its severity.

Background: Several factors that increase the risk of severe food-induced anaphylaxis have been identified. Objective: We aimed to determine the demographic, etiologic, and clinical features of food-induced anaphylaxis in early childhood and also any other factors associated with severe anaphylaxis. Methods: We carried out a medical chart review of anaphylaxis cases from 16 pediatric allergy and immunology centers in Turkey. Results: The data of 227 patients with 266 food-induced anaphylaxis episodes were included in the study. The median (interquartile range) age of the first anaphylaxis episode was 9 months (6-18 months); 160 of these patients were boys (70.5%). The anaphylaxis episodes were mild in 75 cases (28.2%), moderate in 154 cases (57.9%), and severe in 37 cases (13.9%). The most frequent food allergens involved were cow's milk (47.4%), nuts (16.7%), and hen's egg (15.8%). Epinephrine was administered in only 98 (36.8%) of these anaphylaxis episodes. A logistic regression analysis revealed two statistically significant factors that were independently associated with severe anaphylaxis: the presence of angioedema and hoarseness during the anaphylactic episode. Urticaria was observed less frequently in patients who developed hypotension. In addition, confusion and syncope were associated with 25.9- and 44.6-fold increases, respectively, in the risk of concomitant hypotension. Conclusion: Cow's milk, nuts, and hen's egg caused the majority of mild and moderate-to-severe anaphylaxis episodes. The presence of angioedema and hoarseness in any patient who presents with a history of food-induced anaphylaxis should alert clinicians that the reaction may be severe. In addition, the presence of confusion, syncope, or stridor probably indicates concomitant hypotension.

Identifying the effects of scientific information and recommendations on physicians' prescribing behavior.

We investigate how the prescribing behavior of physicians reacts to scientific information and recommendations released by public authorities. Taking the example of antidepressant drugs, we use French panel data on exhaustive prescriptions made by a representative sample of general practitioners to more than 110,000 depressed patients between 2000 and 2008. New results revealing an increase in suicidal thinking among children taking selective serotonin reuptake inhibitors (SSRIs) were reported in 2004 and prompted the release of new guidelines by public health authorities. We identify the effect of this unexpected warning on physicians' drug choices while addressing the possibility that patients heterogeneity may be correlated with unobserved physician characteristics. While the warning decreased the average probability of prescribing SSRIs, we find that physicians' responses to the warning were very heterogeneous and larger if the physician had a higher preference for prescribing SSRIs before the warning.

Proven Food-Induced Acute Urticaria and Predictive Factors for Definitive Diagnosis in Childhood.

BACKGROUND: Urticaria can be the only sign of a food allergy or can be seen together with other signs and symptoms of a food allergy. OBJECTIVE: To determine the demographic, etiologic, and clinical features of food-induced acute urticaria in childhood. METHODS: Patients suspected of food-induced acute urticaria were included in this prospective cross-sectional multicenter study. RESULTS: Two hundred twenty-nine urticaria cases were included in this study. Seventeen patients who did not meet the inclusion criteria of the study were excluded. Of the 212 included cases, 179 (84.4%) were diagnosed with definitive food-induced acute urticaria. The most common foods causing acute urticaria were cow's milk, hen's eggs, and nuts in 56.4, 35.2, and 19% of cases, respectively. The positive predictive value of a history of milk-induced acute urticaria together with a milk-specific IgE >5 kU/L for cow's milk-induced acute urticaria was 92% (95% CI: 81-96%). A history of cow's milk-induced and/or hen's egg-induced acute urticaria was consistent with a definitive diagnosis of food-induced urticaria (Chen's kappa: 0.664 and 0.627 for milk and eggs, respectively). Urticaria activity scores were higher in patients with food-induced acute urticaria (p = 0.002). CONCLUSION: Cow's milk, hen's eggs, and nuts were the most common allergens in the etiology of childhood food-induced acute urticaria. Although the urticaria activity score provides guidance for diagnosis, an oral food challenge is often essential for the definitive diagnosis of a patient with a history of food-induced acute urticaria.

Adolescents with asthma reported more peer victimization, more anger repression, and less anger expression.

OBJECTIVE: The aim of this study was to investigate the peer victimization and anger expression in adolescents with asthma. The relationship between asthma control and psychological features was also examined. METHODS: The study was a cross-sectional study with a healthy control group. The sample of the study was composed of 61 adolescents who were previously diagnosed by a physician with asthma of various intensities. Sixty adolescents with no chronic disorders were enrolled as the control group. Peer victimization was examined using the Multidimensional Peer Victimization Scale (MPVS). The State-Trait Anger Expression Inventory (STAXI) was used to assess anger expression styles. Emotional and behavioral symptoms of the adolescents were measured using the Strengths and Difficulties Questionnaire (SDQ). RESULTS: Adolescents with asthma reported more peer victimization in the subscales of physical, social, verbal, attacks on property, and frightening in the MPVS; and having more problems in emotional, social, and peer relations areas in the SDQ (p < .001 for all subscales) compared to the control group. The results were similar between the groups regarding the conduct problems and hyperactive behaviors. The adolescents with asthma reported more anger repression and less anger expression than the control group (p < .001 for both subscales). CONCLUSIONS: The results indicated that the adolescents with asthma were subjected to more peer victimization and experienced more difficulties in anger expression than the controls. Based on the findings of this study, we suggest that these psychological factors should be kept in mind during the management of asthma in adolescents.

Physicians' Approach to Anaphylaxis in Childhood.

METHODS: A questionnaire form consisting of a total of 18 questions was prepared. Six questions concerned demographic data; 7 questions inquired about physician's knowledge level about treatment of anaphylaxis. In the last part, 5 different case scenarios were given, and their diagnoses and treatments were asked. RESULTS: A total of 120 physicians participated in the study. Of the participants, 66.7% were residents. The rate of correct answer about dose of epinephrine was 57.5%. The rates of making correct diagnoses in anaphylaxis case scenarios 1, 2, and 3 were 60%, 73.3%, and 91.7%, respectively, whereas epinephrine administration rates were 54%, 67.5%, and 92.5%, respectively. When the answers of all these questions given by the residents and specialists and among physicians who updated and did not update were compared, there were no statistically significant differences except epinephrine administration rate and its route (P < 0.05). CONCLUSIONS: The results of the current study suggest that physicians' knowledge levels were inadequate in making the diagnosis of anaphylaxis, and physicians use epinephrine in conditions without hypotension or an undefined possible/known allergen contact. Information about epinephrine administration was partially correct. It is currently considered to be the simplest measure to have a written anaphylaxis action plan including diagnostic criteria for anaphylaxis.

Infant colic or early symptom of autism spectrum disorder?

BACKGROUND: Gastrointestinal (GI) disorders are common in autism spectrum disorder (ASD). Infant colic (IC), the functional GI disorder of infancy, has not been evaluated in this patient group. The aim of this study was therefore to determine the rate of IC in ASD and investigate a possible association between ASD and IC. METHODS: The subjects consisted of 100 ASD patients (mean age, 6.6 ± 3.5 years) and 100 healthy controls (mean age, 5.3 ± 2.8 years). The parents were questioned using the diagnostic criteria for infant colic for clinical research purposes defined in Rome IV to diagnose IC, retrospectively. The sample size was estimated using a maximum type I error probability of 5% (alpha) and a type II error of 20%. RESULTS: The rate of IC was 16% and 17% in the ASD group and control group, respectively (P ˃ 0.05). Excessive crying with late onset and long duration in infants was defined as persistent crying. The rate of persistent crying was significantly higher in the ASD group than in the control group (32% vs 9%, P < 0.001). The relative risk of persistent crying was 4.40 in ASD. The likelihood of being misdiagnosed with IC in this group was 78%. CONCLUSION: The rate of IC is not increased in patients with ASD, but infants with excessive crying should be very thoroughly evaluated before being diagnosed with IC. In particular, persistent crying in infants (i.e. excessive crying with late onset and long duration) may be an early symptom of ASD.

Administración satisfactoria de la vacuna triple viral mediante una prueba de provocación gradual en una paciente con anafilaxia después de una vacunación previa / Successful administration of measles-rubella-mumps vaccine by graded challenge in a case with anaphylaxis after prior vaccination

La alergia al huevo es una de las alergias alimentarias más frecuentes durante la niñez, junto con la alergia a la leche de vaca. La vacuna triple viral (VTV), contra el sarampión, la rubéola y las paperas, es parte del calendario de vacunación pediátrica y contiene proteína de huevo. La recomendación aceptada en la actualidad es que la VTV debe administrarse en una sola dosis y bajo supervisión médica en los pacientes con alergia al huevo. Si bien se ha informado que la VTV es segura para estos pacientes, algunos tuvieron anafilaxia. En general, la anafilaxia después de una vacunación previa se considera una contraindicación. En este artículo, presentamos el caso de la administración satisfactoria de la VTV mediante el incremento gradual de la dosis a una paciente que tuvo anafilaxia después de una vacunación previa.

Egg allergy is one of the most common food allergies during childhood along with cow's milk allergy. The measles-mumps-rubella (MMR) vaccine is included in the pediatric immunization schedule and contains egg protein. The currently accepted opinion is that the MMR vaccination should be done in a single dose under medical observation in patients with egg allergy. Although it is reported that the MMR vaccine is safe for that patients, there are some patients who developed anaphylaxis. Generally, the development of anaphylaxis after the previous vaccination is reported as a contraindication. We present a successful administration of MMR vaccine by gradually increased doses for a patient who developed anaphylaxis after the previous vaccination.

Pediatricians' approach to children with acute urticaria.

BACKGROUND: Acute urticaria is a common condition in childhood that concerns both patients and pediatricians. The aim of this study was to evaluate the general approach of pediatricians to children with acute urticaria. METHODS: A data collection form consisting of 17 questions was created to evaluate pediatricians' general knowledge and practical approaches about urticaria. This form was distributed at the hospitals where pediatricians and pediatric residents work. The data was recorded in SPSS for Windows v.15 (SPSS, Inc., Chicago, IL, USA). The frequency (%) was used for descriptive data, while Pearson χ2 and Fisher's Exact tests were used for comparisons between groups. P<0.05 was considered significant. The study was approved by the local ethics committee. RESULTS: Pediatricians suggest that foods and food additives are the most common etiological factors in the development of urticaria and, therefore, often advise dietary changes. Second-generation antihistamines are preferred for treatment and are administered for about 5-7 days. Pediatric residents were found to prefer parenteral drug administration for the treatment of urticaria. A different generation antihistamine therapy was applied for treatment of patients who did not respond to the initial treatment. It was also determined that patients were referred to allergists when urticaria was accompanied by angioedema or when patients were resistant to conventional treatment. CONCLUSIONS: Pediatricians' knowledge regarding the diagnosis and treatment of urticaria was less extensive than expected. According to the results, there was some confusion among physicians regarding the etiological role of some foods in acute urticaria and the strategies for removal of these foods from the diet during the treatment. Participants' treatment approaches were partially correct and sufficient. In general, there were no differences observed between pediatric residents and pediatricians in terms of the management of patients with urticaria, except the route of administration.

Cross-reactivity syndromes: presentation of two cases and review of the literature.

Cross-reactivity has important consequences in some immune disorders, including allergic and autoimmune diseases, which can affect both diagnostic and therapeutic approaches. One of the most common cross-reactivity syndromes is pollen-food syndrome (PFS). The patient is sensitized with pollen by the airways and exhibits an allergic reaction to food antigen with a structural similarity to the pollen. PFS usually presents with pruritus and swelling of the mouth and throat during or just after ingestion of fresh, uncooked fruits and vegetables. Latex fruit syndrome is another cross-reactivity syndrome. It is the association of latex allergy and allergy to plant foods, which affects up to 50% of latex-allergic patients. Here, we present two cases with crossreactivity syndrome.

Rapid and easy diagnosis of Netherton syndrome with dermoscopy.

BACKGROUND: Netherton syndrome is a rare autosomal recessive disease demonstrating ichthyosis linearis circumflexa, atopic findings, and hair shaft anomalies. Trichorrhexis invaginata is the pathognomonic hair shaft anomaly seen in this syndrome. OBJECTIVE: In recent years, hair shaft anomalies have been described as "matchstick" and "golf tee" signs. We present a patient with Netherton syndrome diagnosed by the presence of matchstick and golf tee hairs in addition to trichorrhexis invaginata.

Expectoration of a foreign body at the late period: A case report.

Foreign body (FB) aspiration is a relatively common problem in children, particularly during the first 3 years of life. It is an emergency condition and the removal of the FB by bronchoscopy is the primary treatment. Children with undiagnosed retained foreign bodies may present with respiratory symptoms including recurrent or persistent wheezing, with or without respiratory failure. Spontaneous expectoration of a FB is a rare occurrence. Herein, we present a case that was diagnosed with FB aspiration during investigation for persistent wheezing and who expectorated part of a sunflower seed 2 months after aspiration.

Use of complementary and alternative medicine in children who have no chronic disease.

AIM: In this study, we aimed to evaluate complementary and alternative methods of medicine, determine the frequencies of usage of these methods and investigate the factors which have an impact on their usage. MATERIAL AND METHODS: The study was conducted between October, the 15(th) and November, the 15(th) 2012. Approval was obtained from the local ethics committee (08.10.2012/732). The study form prepared was applied to the mothers of the children who presented to our general outpatient clinic and had no chronic disease. The data were recorded in SPSS for Windows v.16 program. Descriptive statistics, chi-square, Mann-Whitney U and logistic regression analyses were applied. A p value of <0.05 was considered significant. RESULTS: Two hundred and six children were included in the study. Complementary and alternative medicine was used in 83% of the patients. Wearing an evil eye (45%) bead and prayer (35%) to protect from the evil eye were the most commonly used methods. The most common medical conditions which caused to use of complementary and alternative medicine included anemia, diarrhea, constipation and cough. Belief-based application were being used in 73% of the patients and herbal methods were being used in 57%. In 18% of the patients, interventional methods including cutting had been performed. No difference was found between the patients in whom these methods were used and not used in terms of familial income, education levels of the parents, family type and residence (p>0.05). CONCLUSIONS: Complementary and alternative methods of medicine are applied substantially frequently in children. Physicians should have information about these methods in terms of their effects and side effects and warn families and especially mothers about potential risks.

The effects of suplatast tosilate treatment and prophylaxis on lung histopathology in a mouse model of chronic asthma.

INTRODUCTION: Suplatast tosilate is a medication that inhibits TH2-type cytokines. We aimed to investigate the effects of suplatast tosilate treatment and prophylaxis on lung histopathology and cytokine levels in a mouse model of chronic asthma. MATERIALS AND METHODS: Forty-two BALB/c mice were divided into 6 groups: group I (control), group II (vehicle control), group III (dexamethasone), group IV (prophylaxis with suplatast tosilate), group V (treatment with suplatast tosilate), and group VI (prophylaxis and treatment with suplatast tosilate). All of the groups, except for the control and vehicle control groups, were sensitized and challenged with ovalbumin. The mice in the study groups, except those in the group receiving suplatast tosilate for prophylaxis only, were treated with study drugs. After the mice were killed, IL-4, IL-5, and interferon-γ levels were quantified in the lung tissue, which were examined histologically by light and electron microscopy. RESULTS: There were significant improvements in all histopathological parameters in the group treated with suplatast tosilate compared with the vehicle control group. Similar improvements were observed when the group receiving prophylaxis and treatment with suplatast tosilate was compared with the vehicle control as well. There were no significant differences between the group receiving only prophylaxis with suplatast tosilate and the vehicle control group. Cytokine levels were significantly higher in the vehicle control group when compared with the control group. Although all of the groups had lower cytokine levels than those of the vehicle control group, the differences were not statistically significant. CONCLUSIONS: Treatment with suplatast tosilate was effective in improving all histopathological parameters in a mouse model of chronic asthma. It was observed that the use of prophylactic suplatast tosilate was ineffective and had no additional effects when administered together with treatment.
