A Comprehensive Assessment of Long-Term Complications in Patients with Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis.

Introduction: Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and SJS/TEN overlap syndrome are rare severe hypersensitivity reactions that lead to epithelial sloughing. Studies investigating the chronic multisystem effects of these syndromes and assessing patients in terms of quality of life (QOL), depression, and anxiety in the pediatric population are limited. In this study, we aimed to investigate the long-term effects of these diseases from a multisystem perspective.

Clinical characteristics of patients requiring lung transplantation referral in national cystic fibrosis registry data.

Background: We aimed to determine the number of cystic fibrosis (CF) patients recorded in the Cystic Fibrosis Registry of Türkiye (CFRT) who were in need of lung transplantation (LT) referral and examine clinical differences between patients who were LT candidates due to rapid forced expiratory volume in one second (FEV₁) decline and LT candidates without rapid FEV₁ decline in the last year to identify a preventable cause in patients with such rapid FEV₁ decline.

Methods: All CF patients recorded in the CFRT in 2018 were evaluated in terms of LT. Patients were divided into those with FEV₁ below 50% and in need of LT due to a decrease of 20% or more in the previous year (Group 1) and those who did not have FEV₁ decline of more than 20% in the previous year but had other indications for LT (Group 2).

Several factors that increase the risk of severe food-induced anaphylaxis have been identified. 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. We carried out a medical chart review of anaphylaxis cases from 16 pediatric allergy and immunology centers in Turkey.

Clinical findings of patients with cystic fibrosis according to newborn screening results.

Background: Cystic fibrosis (CF) is a lethal recessive genetic disease caused by loss of function associated with mutations in the CF trans-membrane conductance regulator. It is highly prevalent (approximately 1 in 3,500) in Caucasians. The aim of this study was to compare demographic and clinical features, diagnostic tests, treatments, and complications of patients with CF whose newborn screening (NBS) with twice-repeated immune reactive trypsinogen testing was positive, normal, and not performed.

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.

Evaluation of pulmonary findings in patients with humoral immunodeficiency.

Aim: To determine the frequency of sinopulmonary infections, detect changes in the respiratory system, and measure functional capacity of the lungs in our patients with humoral immunodeficiency.

Patients eligible for modulator drugs: Data from cystic fibrosis registry of Turkey.

Background: A better understanding of cystic fibrosis transmembrane conductance regulator biology has led to the development of modulator drugs such as ivacaftor, lumacaftor-ivacaftor, tezacaftor-ivacaftor, and elexacaftor-tezacaftor-ivacaftor. This cross-sectional study evaluated cystic fibrosis (CF) patients eligible for modulator drugs.

Methods: Data for age and genetic mutations from the Cystic Fibrosis Registry of Turkey collected in 2018 were used to find out the number of patients who are eligible for modulator therapy.

Clinical features and accompanying findings of Pseudo-Bartter Syndrome in cystic fibrosis.

Background: Pseudo-Bartter syndrome (PBS) is a rare complication of cystic fibrosis (CF) and there are limited data in the literature about it. We aimed to compare clinical features and accompanying findings of patients with PBS in a large patient population.

Methods: The data were collected from the Cystic Fibrosis Registry of Turkey where 1170 CF patients were recorded in 2017.

Cystic fibrosis in Turkey: First data from the national registry.

Background: Cystic fibrosis (CF) care has been implemented in Turkey for a long time; however, there had been no patient registry. For this purpose, the Turkish National CF Registry was established. We present the first results of registry using data collected in 2017.

Perceptions of parents and physicians concerning the Childhood Asthma Control Test.

Background: The Childhood Asthma Control Test (C-ACT) has been proposed to be a simple, patient-based test that is able to reflect the multidimensional nature of asthma control. In this analysis, the aim was to evaluate the perceptions of physicians and caregivers concerning C-ACT and its predictive value for future asthma-related events.

Method: In a multicenter prospective design, 368 children aged 4-11 years with asthma who were either well- or not well-controlled were included in the study.

Airborne pollen in European and Asian parts of Istanbul.

Pollen concentrations in the atmosphere of Istanbul, a city located between two continents, has been monitored for 1 year as part of a larger research program. The sampling sites were located in two different continents: the Asian part (AS) and the European part (EP). The sampling was performed in AS and EP of the city by using Hirst type volumetric method, and pollen grains of 58 and 62 taxa were identified in the two parts, respectively.

During 2 years, a total of 57,124 pollen grains/m(3), which belonged to 66 taxa and 869 unidentified pollen grains, were recorded. In the region investigated, Pinus sp.

A multi-center survey of childhood asthma in Turke--I: the cost and its determinants.

Successful management of childhood asthma requires a thorough idea of the economic impact of asthma and its determinants, as policy makers and physicians inevitably influence the outcome. The aim of this study was to define the cost of childhood asthma in Turkey and its determinants. In April 2006, a multi-center, national study was performed where data regarding cost and control levels were collected.

Risk factors for wheezing in primary school children in Bursa, Turkey.

Background: Wheezing is the most common symptom of childhood respiratory tract illnesses. It is important not only for its associated acute morbidity, but also for the fact that early childhood wheezing confers a high risk for asthma. Epidemiological studies from various countries show that 10-15% of children <1 year of age and 25% of children <5 years of age have wheezing-associated respiratory tract illness, and one-third of these children develop asthma later in life.
