Juvenile dermatomyositis associated interstitial lung disease, rarely seen in pediatric age groups, has adverse effects on survival. Anti-melanoma differentiation associated gene 5, one of the identified autoantibodies in juvenile dermatomyositis, preferentially affects the lung tissue and may cause rapidly progressive interstitial lung disease. It is a major cause of mortality in juvenile dermatomyositis. In this case report, we present a pediatric patient diagnosed with juvenile dermatomyositis without anti-melanoma differentiation associated gene 5 antibody positivity.Publication Metadata only Pediatric flexible bronchoscopy in the intensive care unit: A multicenter study(2021-07-01T00:00:00Z) Atag, Emine; Unal, Fusun; YAZAN, HAKAN; Uyan, Zeynep Seda; ERGENEKON, ALMALA PINAR; Yayla, Esra; Mertturk, Edanur; Telhan, Leyla; Meral, Ozge; KÜÇÜK, HANİFE BÜŞRA; Gunduz, Mehmet; GÖKDEMİR, YASEMİN; ERDEM ERALP, ELA; KIYAN, GÜRSU; ÇAKIR, Erkan; GİRİT, SANİYE; Karakoc, Fazilet; Oktem, Sedat; YAZAN, HAKAN; KÜÇÜK, HANİFE BÜŞRA; ÇAKIR, ERKANIntroduction Flexible bronchoscopy (FB) is frequently used for assessment and treatment of patients with respiratory diseases. Our aim was to investigate the contribution of FB to diagnosis and therapy in children admitted to the intensive care units (ICU) and to evaluate the safety of FB in this vulnerable population. Methods Children less than 18 years of age who underwent FB in the five neonatal and pediatric ICUs in Istanbul between July 1st, 2015 and July 1st, 2020 were included to the study. Demographic and clinical data including bronchoscopy indications, findings, complications, and the contribution of bronchoscopy to the management were retrospectively reviewed. Results One hundred and ninety-six patients were included to the study. The median age was 5 months (range 0.3-205 months). The most common indication of FB was extubation failure (38.3%), followed by suspected airway disease. Bronchoscopic assessments revealed at least one abnormality in 90.8% patients. The most common findings were airway malacia and the presence of excessive airway secretions (47.4% and 35.7%, respectively). Positive contribution of FB was identified in 87.2% of the patients. FB had greater than 1 positive contribution in 138 patients and 80.6% of the patients received a new diagnosis. Medical therapy was modified after the procedure in 39.8% and surgical interventions were pursued in 40% of the patients. Therapeutic lavage was achieved in 18.9%. There were no major complications. Conclusion Flexible bronchoscopy is a valuable diagnostic and therapeutic tool in neonatal and pediatric ICUs and is not associated with major complications.Publication Open Access A Rare Cause of Pulmonary Hypertension in a 4-Year-Old Toddler: Association of Cor Triatriatum Sinister and Pulmonary Arteriovenous Malformation(2020-11-01T00:00:00Z) Yozgat, Can Yilmaz; ÇAKIR, Erkan; YAZAN, HAKAN; OTÇU TEMUR, Hafize; YAKUT, KAHRAMAN; YOZGAT, YILMAZ; ÇAKIR, ERKAN; YAZAN, HAKAN; OTÇU TEMUR, HAFİZE; YAKUT, KAHRAMAN; YOZGAT, YILMAZCor triatriatum sinister is a rare congenital cardiac anomaly. The anomaly is caused by a fibromuscular membrane that divides the left atrium into two cavities. This membrane can lead to the obstruction of left atrial flow and also create pulmonary venous hypertension. Pulmonary arteriovenous malformation (PAVM) is notorious for its aberrant blood flow between the pulmonary arteries and veins. Herein, we report a case of a 4-year-old toddler who had a unique form of pulmonary hypertension presenting with cor triatriatum sinister and diffuse PAVM. After the surgical treatment of cor triatriatum sinister, both pulmonary arteriovenous malformation and pulmonary hypertension disappeared.Publication Open Access CLINICAL AND RADIOLOGICAL EVALUATION OF PATIENTS WITH POSTINFECTIOUS BRONCHIOLITIS OBLITERANS(2019-06-01T00:00:00Z) ÇAKIR, Erkan; Khalif, Fatouma; BİLGİN, MEHMET; Al Shadfan, Lina; YAZAN, HAKAN; YILMAZ, İREM; NURSOY, MUSTAFA ATİLLA; BİLGİN, MEHMET; YAZAN, HAKAN; YILMAZ, İREM; NURSOY, MUSTAFA ATİLLAPublication Metadata only Balanced Double Aortic Arch Causing Persistent Respiratory Symptoms Mimicking Asthma in an Infant(2020-09-01T00:00:00Z) OTÇU TEMUR, Hafize; Yozgat, Can Yilmaz; UZUNER, SELÇUK; Ugurlucan, Murat; YAZAN, HAKAN; ÇAKIR, Erkan; YOZGAT, Yılmaz; OTÇU TEMUR, HAFİZE; UZUNER, SELÇUK; YAZAN, HAKAN; ÇAKIR, ERKAN; YOZGAT, YILMAZDouble aortic arch (DAA) is a common form of complete vascular ring. The state of the condition leads to upper airway impediment and compression of the esophagus. A balanced DAA is an extremely rare anomaly. The anatomical aberration cannot be easily diagnosed with echocardiography when an infant has chronic respiratory distress. Herein, we present the case of an 11-month-old girl who had chronic respiratory distress and a balanced DAA.Publication Open Access A Rare Presentation of Acquired Laryngomalacia and Tracheomalacia in a Child Associated with Apricot Sulfurization(2020-12-01T00:00:00Z) Vehapoğlu Türkmen, Aysel; Çakır, Erkan; Uzuner, Selçuk; Çalım, Ömer Faruk; Yazan, Hakan; VEHAPOĞLU TÜRKMEN, AYSEL; ÇAKIR, ERKAN; UZUNER, SELÇUK; ÇALIM, ÖMER FARUK; YAZAN, HAKANSulfur fumigation has come to replace traditional sun drying methods for drying fruits over the years around the world as it is a cheaper and faster method because of its pesticidal and anti-bacterial properties. We report the case of an 11-year-old boy with acquired severe biphasic stridor who was exposed to extremely high concentrations of sulfur dioxide (SO2) during apricot sulfurization processes with his mother. The patient's bronchoscopy revealed severe glottic and subglottic damage. Exposure to SO2 is a health risk, particularly for individuals who are sulfide-sensitive, especially in childhood. The pulmonary epithelium may be directly injured by inhaled toxic substances at various levels of the respiratory system. To the best of our knowledge, this is the first case reported of acquired airway damage associated with sulfurization in a pediatric patient without a known history of any respiratory disease or symptoms.
