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 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.

P. , YILMAZ YEĞİT C., Cenk M., Gulieva A., Kalyoncu M., SELÇUK M., DOĞRU Ö., ERDEM ERALP E., GÖKDEMİR Y., Karakoc F., et al.Background and Aim Pulmonary embolism (PE) is a potentially life-threatening disease in children. The objective of the study is to evaluate the utility of adult-based pulmonary embolism rule-out criteria (PERC), Pediatric PE Model, and D-dimer in the diagnosis of PE in children. Material and Methods The study consisted of patients under 18 years of age who were consulted to the Pediatric Pulmonology Clinic for the evaluation of PE. Patients were divided into two groups based on the confirmation of PE. The group with the presence of PE (n = 20) consisted of children who were diagnosed with PE. The group with the absence of PE (n = 28) consisted of children with clinically suspected PE but negative diagnostic imaging. Adult validated clinical decision PERC rule and Pediatric PE Model were retrospectively applied to the patients. Results In the study, PERC demonstrated a sensitivity of 60% and a specificity of 46% for the diagnosis of PE in children. When PE Model was evaluated for the children, it was found a 50% sensitivity and 75% specificity. Combining PE Model and PERC rule with D-dimer did not increase the specificity and sensitivity. Smoking was found to be relevant for PE in the childhood. Twenty-five percent of the patients had a genetic tendency for PE. All of the patients had an underlying disease as well. Conclusion None of the current risk assessment tools (PE Model, PERC, D-dimer) were found to be accurate in predicting PE. Further larger population studies are still required to develop a better diagnostic approach.Publication Metadata only Polisomnografi aracılığıyla tanı alan bir nöroblastom olgusu(2019-10-11) ERGENEKON, ALMALA PINAR; ERDEM ERALP, ELA; GÖKDEMİR, YASEMİN; EKER, NURŞAH; TOKUÇ, AYŞE GÜLNUR; KARADAĞ, BÜLENT TANER; YILMAZ YEĞİT C., ERGENEKON A.

T.Publication Metadata only Health-related quality of life in patients with bronchiolitis obliterans(WILEY, 2020) KARADAĞ, BÜLENT TANER; Atag, Emine; Ikizoglu, Nilay Bas; Ergenekon, Pinar; Kalin, Sevinc; Unal, Fusun; Gokdemir, Yasemin; Eralp, Ela Erdem; Yalcin, Koray; Oktem, Sedat; Ersu, Refika; Karakoc, Fazilet; Karadag, BulentIntroduction Bronchiolitis obliterans (BO) is mainly caused by infections and hematopoietic stem cell transplantation (HSCT). This study aimed to investigate the health-related quality of life (HRQOL) of children with BO compared to the healthy children and also to assess the HRQOL according to the etiology. Methods Postinfectious (group 1) and post-HSCT BO (group 2) patients and healthy children were included in the study. HRQOL was assessed by the Short Form-36 (SF-36) and St George's Respiratory Questionnaire (SGRQ). Correlations between demographic and clinical characteristics, pulmonary function tests, high-resolution chest tomography scores, and HRQOL were assessed. Results Thirty-seven postinfectious and post-HSCT BO patients and 34 healthy children were included in the study. Mean age was 13.8 +/- 0.7 years. Mean forced vital capacity and forced expiratory volume(1)were 60.7 +/- 2.7% predicted, and 49.8 +/- 3.1% predicted, respectively. The SF-36 scores were lower in BO patients compared to healthy children (P < .01). Patients with better lung functions had higher SF-36 scores, but lower SGRQ. The number of inhaled therapies, acute exacerbations, hospitalizations were inversely correlated with SF-36. A positive correlation was found between these parameters and total SGRQ scores (r = .507,P = .02;r = .409,P = .12;r = .326,P = .049, respectively). SF-36 scores were better in group 1 for subscales of physical role functioning and social role functioning compared to group 2. (P = .01,P = .01, respectively). Conclusion The HRQOL of patients with BO measured by SF-36 was low compared to healthy children. SF-36 scores were more affected in post-HSCT BO patients. HRQOL of children with chronic lung disease should be taken into consideration in the management of these patients.Publication Metadata only Comparison of Conventional Pulmonary Rehabilitation and High-Frequency Chest Wall Oscillation In Primary Ciliary Dyskinesia(WILEY-BLACKWELL, 2014) KARADAĞ, BÜLENT TANER; Gokdemir, Yasemin; Karadag-Saygi, Evrim; Erdem, Ela; Bayindir, Ozun; Ersu, Refika; Karadag, Bulent; Sekban, Nimet; Akyuz, Gulseren; Karakoc, FaziletBackgroundEnhancement of mucociliary clearance by pulmonary rehabilitation (PR) is advocated in primary ciliary dyskinesia (PCD). Our primary aim was to compare the efficacy and safety of postural drainage, percussion and vibration [conventional PR (CPR)], and high frequency chest wall oscillation (HFCWO) by studying change in pulmonary function. Our secondary aim was to evaluate patient preferences regarding the two methods. MethodsThis was a controlled randomized crossover study. PCD patients between the ages of 7 and 18 years were assigned to two groups, first group performed airway clearance with CPR at hospital for 5 days and after a 2-day washout period HFCWO was applied to the same group at home. HFCWO was applied first to the other group and then these patients were hospitalized for CPR. The primary outcome measure of the study was pulmonary function test (PFT). The secondary outcomes were pulse arterial oxygen saturation (SpO(2)) and the perceived efficiency and comfort level. ResultsPFT values of patients increased significantly after both PR methods (before/after): CPR: FVC: 77.014.1/81.8 +/- 13.0 (P=0.002); FEV1: 72.9 +/- 14.8/78.7 +/- 13.5 (P=0.001); PEF: 73.8 +/- 14.5/82.5 +/- 14.5 (P=0.001); FEF25-75: 68.6 +/- 27.6/74.9 +/- 29.3 (P=0.007). HFCWO: FVC: 75.1 +/- 15.3/80.3 +/- 13.9 (P=0.002); FEV1: 71.4 +/- 16/77.4 +/- 14.6 (P=0.001); PEF: 70.9 +/- 18.0/78.3 +/- 17.7 (P=0.002); FEF25-75: 70.5 +/- 23.4/76.4 +/- 25.6 (P=0.006). There were no significant differences in % predicted FVC, FEV1, PEF, and FEF25-75 increased values with CPR and HFCWO. HFCWO was found more comfortable (P=0.04). Two PR methods were found efficient and no desaturation occurred during PR. ConclusionsPFTs were significantly increased after both PR methods. There were no differences in PFTs and SpO(2) between the CPR and HFCWO groups. Both PR methods were found efficient. HFCWO was found more comfortable. HFCWO may be an option in patients with chronic pulmonary disease and low adherence to PR. Pediatr Pulmonol. 2014; 49:611-616.

Yet, little is known about the genetic profile of CF patients in Turkey. This study sought to determine the mutation distribution among CF patients seeking care at Marmara University. MethodsTwo hundred fifty previously diagnosed CF patients were included in the study. CFTR gene exons 1 to 27 were amplified by a polymerase chain reaction and whole DNA sequencing was performed. Duplications and deletions were investigated by the multiplex ligation-dependent probe amplification (MLPA) technique in patients with one or two unidentified mutations in sequence analysis. ResultsCFTR mutation analysis revealed 80 mutations and five large deletions were present in our study population. The five most common mutations were (delta) F508 (c.1521-1523delCTT) (28.4%), 1677delTA (c.1545-1546delTA) (6.4%), 2789+5G->A (c.2657+5G>A) (5.8%), N1303K (c.3909C>G) (2.4%), and c.2183AA->G (c.2051-2052delAAinsG) (4.0%). Large deletions were found in 16 patients. Four novel mutations and two novel deletions were detected in this study. ConclusionsWe have identified four novel mutations and two novel deletions using next-generation DNA sequencing and the MLPA technique and obtained an overall mutation detection rate of 91.4%. Detection of novel variants in CF patients will assist in genetic counseling and in determining appropriate patients for new therapies.Publication Metadata only Sleep disordered breathing and sleep quality in children with bronchiolitis obliterans(WILEY, 2016) KARADAĞ, BÜLENT TANER; Uyan, Zeynep S.; Turan, Ihsan; Ay, Pinar; Cakir, Erkan; Ozturk, Ersin; Gedik, Ahmet H.; Gokdemir, Yasemin; Erdem, Ela; Sen, Velat; Karadag, Bulent; Karakoc, Fazilet; Ersu, RefikaThe incidence of sleep-disordered breathing (SDB) increases in chronic lung diseases. Our aim was to evaluate SDB and sleep quality in children with postinfectious bronchiolitis obliterans (BO) and assess associated risk factors. We hypothesized that children with BO are at increased risk for SDB and have impaired sleep quality. We also hypothesized that severity of SDB and impairment of sleep quality is related to the severity of lung disease. Sleep Related Breathing Disorder (SRBD) subscale of the Pediatric Sleep Questionnaire (PSQ) and Pittsburgh Sleep Quality Index (PSQI) questionnaires; spirometry, impulse oscillometry (IOS), and overnight polysomnography (PSG) were performed. Twenty-one patients (14 male, median age: 8.3 years) were enrolled. Five patients (25%) had a PSQ score of >0.33, predictive of a SDB. Ten patients (48%) had poor sleep quality. Four patients (19%) had an OAHI of >1/hr. Nineteen patients (90%) had a high desaturation index. Four patients (19%) had a mean oxygen saturation of <93%. Median central apnea time was 7.5 (IQR: 6.9-9.1) seconds. Central apnea index of the patients correlated positively with R5, R10, R15, R20, Z5, and negatively with X10 and X15 at IOS. There was a positive correlation between the lowest oxygen saturation and FVC, FEV1, X5, X10, X15, X20 while there was a negative correlation between lowest saturation and the central apnea index at PSG, R5, R10, and Z5 at IOS. Mean oxygen saturation during PSG correlated positively with FVC, FEV1, FEF25-75, X5, X10, X15, X20 results. The risk of nocturnal hypoxia is increased in patients with BO and correlated to the severity of lung disease determined by pulmonary function tests. Although BO patients have a shorter duration of central apneas, they are more prone to desaturate. Pediatr Pulmonol. 2016;51:308-315. (c) 2015 Wiley Periodicals, Inc.
