Publication Metadata only Foreign body aspiration: What is the outcome?(WILEY-LISS, 2002) YILDIZELİ, BEDRETTİN; Karakoc, F; Karadag, B; Akbenlioglu, C; Ersu, R; Yildizeli, B; Yuksel, M; Dagli, EUndiagnosed and retained foreign bodies may result in serious complications such as pneumonia, atelectasis, or bronchiectasis. We reviewed a total of 174 children with foreign body aspiration (FBA). Clinical, radiological, and bronchoscopic findings of these patients were evaluated according to the nature of foreign body and elapsed time from aspiration to diagnosis. Significant differences were noted between patients with organic and inorganic FBA in terms of clinical and radiological findings. Cough, recurrent pneumonia, and fever were the most common presenting symptoms in patients with delayed diagnosis. Long-term follow-up was available for 110 patients for a mean duration of 37.8 +/- 23.7 months (range, 1-88 months). We evaluated the course of recovery after bronchoscopic removal. Organic FBA was of comparable duration as for inorganic FBA, and prolonged follow-up was associated with increased risk of persistent symptoms and bronchiectasis (P < 0.001). The risk of long-term complications increased with increasing elapsed time from aspiration to diagnosis; complications were as high as 60% in children who were diagnosed 30 days after FBA (P = 0.0035). Bronchiectasis was a major complication, found in 25% of patients whose diagnosis was delayed by more than 30 days (P = 0.0001). Three patients with bronchiectasis underwent lobectomy. Patients with persistent asthma-like symptoms such as cough and wheezing required treatment with inhaled corticosteroids and bronchodilators. The positive response to this treatment was thought to be a confirmation of the development of transient bronchial hyperresponsiveness induced by foreign bodies. We conclude that timely diagnosis and appropriate treatment of FBA is important to prevent long-term complications in affected children.

The disease is heterogeneous and classified into six groups. Pulmonary parenchymal involvement may be a feature of several subtypes of NPD, including type B. Progressive pulmonary involvement in NPD type B is a major cause of morbidity and mortality It is usually diagnosed at older ages. Only a few cases with early pulmonary involvement have been reported. In this report, a patient with NPD type B, hospitalized with the diagnosis of pneumonia at age 3 months, is presented. Following treatment for pneumonia, she continued to have persistent respiratory symptoms and became oxygen-dependent. High-resolution computed tomography of the chest revealed diffuse interstitial changes. During follow-up, the patient developed hepatosplenomegaly. Lung, liver, and bone marrow biopsies showed characteristic findings for NPD. Biochemical studies also confirmed the diagnosis, and the sphingomyelinase enzyme level of the patient was low. Unilateral lung lavage was performed in order to decrease lipid storage as a treatment modality However, there was no clinical or radiological improvement. The patient died at age 15 months due to progressive respiratory failure. Pulmonary involvement is a rare entity in early childhood in patients with NPD type B, but should be considered in the differential diagnosis of persistent interstitial lung disease. It may cause progressive respiratory failure, but the treatment options remain limited.Publication Metadata only Withdrawal of inhaled steroids in children with non-cystic fibrosis bronchiectasis(WILEY, 2008) KARADAĞ, BÜLENT TANER; Guran, T.; Ersu, R.; Karadag, B.; Karakoc, F.; Demirel, G. Y.; Hekim, N.; Dagli, E.To study the effects of inhaled steroid withdrawal on bronchial hyperreactivity, sputum inflammatory markers and neutrophilic apoptosis in children with non-cystic fibrosis (non-CF) bronchiectasis. To evaluate the role of inhaled steroids in the treatment of children with non-CF bronchiectasis with specific emphasis on the bronchial hyperreactivity and neutrophilic apoptosis. Twenty-seven children with steady-state non-CF bronchiectasis were evaluated primarily with metacholine challenge tests and apoptotic neutrophil ratios in induced sputum and secondarily with symptom scores, pulmonary function tests and tumour necrosis factor-alpha (TNF-alpha), interleukin-8 (IL-8) levels and neutrophil ratios in induced sputum before and after 12-week withdrawal of inhaled steroids. There were 16 girls and 11 boys. Median (interquartile range) age was 11.4 (9.5-13.6) years, follow-up duration was 3.5 (2-6.5) years. Symptom scores (4 vs. 3; P = 0.27), oxygen saturation (95% vs. 97%; P = 0.06), pulmonary function tests (FEV1: 82% predicted vs. 83% predicted; P = 0.73), sputum neutrophil ratios (29.9% vs. 46.8%; P = 0.20), TNF-alpha (58 pg/mL vs. 44.5 pg/mL; P = 0.55) and IL-8 (2.7 ng/mL vs. 2.4 ng/mL; P = 0.82) levels in induced sputum were similar before and after 12-week withdrawal of inhaled steroids. However, the number of patients with bronchial hyperreactivity increased (37% vs. 63% of patients; P = 0.016) and neutrophilic apoptosis in induced sputum decreased (42.8% vs. 20.2%; P = 0.03) after withdrawal. In this study, 12 week-withdrawal of inhaled steroid treatment resulted in a significant increase in bronchial hyperreactivity and decrease in neutrophil apoptosis, but no change in sputum inflammatory markers in children with non-CF bronchiectasis was observed.Publication Open Access Late Diagnosis of Infants with PCD and Neonatal Respiratory Distress(MDPI, 2020-09-04) KARADAĞ, BÜLENT TANER; Goutaki, Myrofora; Halbeisen, Florian S.; Barbato, Angelo; Crowley, Suzanne; Harris, Amanda; Hirst, Robert A.; Karadag, Bulent; Martinu, Vendula; Morgan, Lucy; O'Callaghan, Christopher; Ozcelik, Ugur; Scigliano, Sergio; Ucros, Santiago; Yiallouros, Panayiotis; Schulzke, Sven M.; Kuehni, Claudia E.Neonatal respiratory distress (NRD) is common among infants with primary ciliary dyskinesia (PCD), but we do not know whether affected neonates receive a timely diagnosis. We used data from the international PCD cohort and assessed the proportion of patients with PCD who had a history of NRD and their age at diagnosis, stratifying by presence of laterality defects. First we analyzed data from all participants diagnosed after 2000, followed by individuals from a subgroup diagnosed using stricter criteria. Among the 1375 patients in the study, 45% had a history of NRD and 42% had laterality defects. Out of the 476 children with definite PCD diagnosis, 55% had a history of NRD and 50% had laterality defects. Overall, 30% of children with PCD were diagnosed during the first 12 months of life. This varied from 13% in those with situs solitus and no NRD, to 21% in those with situs solitus and NRD, 33% in those with situs anomalies but no NRD, and 52% in those with both situs anomalies and NRD. Our results suggest that we need to improve our knowledge of the neonatal presentation of infants with PCD and apply it so that these patients will receive appropriate care sooner.Publication Metadata only Bronchoscopic evaluation of unexplained recurrent and persistent pneumonia in children(WILEY-BLACKWELL, 2013) KARADAĞ, BÜLENT TANER; Gokdemir, Yasemin; Cakir, Erkan; Kut, Arif; Erdem, Ela; Karadag, Bulent; Ersu, Refika; Karakoc, Faziletd Background: Persistent or recurrent pneumonia in children can pose a significant challenge to paediatricians and respiratory physicians. Aim: The aim of this study is to determine the role of flexible bronchoscopy (FB) in evaluation of recurrent or persistent pneumonia that remain otherwise unexplained by non-invasive diagnostic tests in children. Methods: Retrospective evaluation of patients who underwent FB with an indication of recurrent or persistent pneumonia from 1997 to 2011. Results: Among 2600 FB procedures, 434 (17%) were performed with the indication of recurrent or persistent pneumonia. There were 237 (54%) boys. Median age at presentation was 84 months, and median duration of symptoms was 9 months. FB led to specific diagnosis in 33% of the cases. The most common diseases diagnosed by FB were malacia disorders (n: 32, 7%), aspirated foreign body (n: 30, 7%), endobronchial tuberculosis (n: 20, 5%), congenital airway anomalies (n: 14, 3%), mucus plugs (n: 14, 3%), pulmonary haemosiderosis (n: 12, 3%) and middle lobe syndrome (n: 11, 3%). During FB, only 6% of the patients had minor complications such as transient hypoxia, stridor and tachycardia. Conclusions: In our study, FB proved to be a safe and effective tool in evaluation of children with persistent or recurrent pneumonia. FB is indicated for children with recurrent or persistent pneumonia where the underlying diagnosis remains unclear even after non-invasive diagnostic tests.Publication Metadata only Mucoepidermoid carcinoma of the bronchus: A rare entity in childhood(WILEY, 2005) YILDIZELİ, BEDRETTİN; Kut, A; Karadag, B; Karakoc, F; Ersu, R; Yildizeli, B; Kotiloglu, E; Yuksel, M; Dagli, EPublication Metadata only Evaluation of caregiver burden, somatization and sleep quality in mothers of children with cystic fibrosis(2022-12-08) KARAVUŞ, MELDA; GÖKDEMİR, YASEMİN; ERDEM ERALP, ELA; ERGENEKON, ALMALA PINAR; KARADAĞ, BÜLENT TANER; AYVAZ, İLKNUR; HIDIROĞLU, SEYHAN; Ayvaz İ., Karavuş M., Hıdıroğlu S., Atasoy A., Karagöz D.

This is the first CF-specific health-related quality of life (HRQOL) measure validated in a Muslim country. Fifty-one children aged 6-13 years treated at four centers in Turkey and 30 parents participated in this cross-sectional study. Demographic characteristics and disease severity parameters were recorded for all participants. All participants completed the parent or child versions of CFQ-R and KINDL questionnaires at enrollment. Reliability and construct validity analysis were carried out. Both children and parents endorsed a range of responses, with no evidence of floor or ceiling effects. Item-to-total correlations indicated that most items were more highly correlated with their intended scale than competing scales. Good internal consistency was found for majority of child and parent scales. CFQ-R scales correlated significantly with clinical indices of disease severity. Good evidence of convergent validity with a generic HRQOL scale was found. Turkish versions of CFQ-R Child and Parent instruments have demonstrated adequate reliability and validity and can be utilized in clinical trials or integrated into clinical evaluation and follow-up of Turkish children with CF.Publication Open Access Key paediatric messages from the 2018 European Respiratory Society International Congress(EUROPEAN RESPIRATORY SOC JOURNALS LTD, 2019-04) KARADAĞ, BÜLENT TANER; Nenna, Raffaella; Hunt, Katie A.; Dassios, Theodore; Collins, Jennifer J.
