Objective: Chylothorax refers to the presence of chyle in the pleural space. There are multiple etiologies of chylothorax. Our aim in this study was to evaluate the clinical manifestations, causes, and treatment of chylothorax in childhood and also to show the differences between the 2 age groups admitted to a tertiary care children’s hospital. The second aim was to evaluate the clinical and radiologic features of patients diagnosed as having Gorham-Stout disease via chylothorax. Materials and Methods: The archives were reviewed for chylothorax documented in the last 31 years. Twenty-two patients (11 girls and 11 boys) were included. Patients were divided into 2 groups: the younger group aged under 24 months and the older group aged over 24 months. Results: A total of 22 patients had chylothorax, and 10 were aged younger than 24 months. In the younger group, etiologies were in order congenital heart surgery, congenital chylothorax, and Gorham-Stout disease. In the older group, etiologies were Gorham-Stout disease, congenital heart surgery, heart failure, heart transplantation, thrombus, intestinal lymphangiectasia, and idiopathic. The most common treatment in the younger group was the medium-chain triglyceride diet (70%), and in the older group, it was sirolimus (50%). Conclusion: There is a wide variety of underlying etiologies in childhood, so a multidisciplinary approach is important to identify the underlying diagnosis. The common etiologies were postoperative and Gorham-Stout disease in our study. All patients with Gorham-Stout disease had a good prognosis. Gorham-Stout disease should be considered in patients of any age with a diagnosis of chylothorax who have bone lesions. [ABSTRACT FROM AUTHOR]

Objective: Asthma is the most common chronic lung disease in childhood. Difficult-to-treat asthma is defined as the continuation of symptoms or attacks of patients despite step 4 or 5 of Global Initiative for Asthma therapy. In the differential diagnosis of these patients, flexible fiberoptic bronchoscopy is recommended to exclude other lung diseases. In this study, we aimed to examine the clinical and radiologic features and flexible fiberoptic bronchoscopy findings of patients referred to our pediatric pulmonology department due to difficult-to-treat asthma and determine the effects of flexible fiberoptic bronchoscopy on the differential diagnosis and treatment. Materials and Methods: The demographic characteristics and flexible fiberoptic bronchoscopy results of 62 patients who were diagnosed as having difficult-to-treat asthma in our pediatric pulmonology department between January 2015 and June 2020 were evaluated retrospectively. The symptoms, history, medications, physical examination findings, pulmonary function tests, and radiologic findings of patients who underwent flexible fiberoptic bronchoscopy were evaluated.

Nasal gliomas are rare and benign congenital tumors caused by abnormal embryonic development. There are three clinical types as extranasal, intranasal and mixed. These masses are firm, non-pulsatile, gray or pink and clinically obstruct the nasal cavity or cause an extranasal deformity. Radiological examination is necessary to determine if intracranial involvement is present. The treatment requires surgical excision and a multidisiplinary approach. We present a newborn patient who was diagnosed with nasal glioma and underwent surgical excision in this study and discuss the relevant literature. [ABSTRACT FROM AUTHOR]
