Abstract
Background Plastic bronchitis (PB) is a rare and severe lung disease. It can be triggered by influenza virus infection, which is a common respiratory infection in children. Bronchoscopy can aid in the early detection and treatment of PB. However, the outcomes and risk for PB development in pediatric patients with influenza virus infection are not fully understood. Methods Data from 321 children diagnosed with influenza virus pneumonia who underwent bronchoscopy examinations between 1st January, 2009 and 31st December, 2020 were retrospectively analyzed to assess the outcomes and risk factors associated with PB development. Results This study included 97 girls and 224 boys with influenza virus pneumonia with a median age of 42 months. Among them, 36 patients (11.2%) were categorized as having PB based on bronchoscopy findings. PB patients had significantly longer fever durations (p=0.010) and higher risks of developing severe conditions including respiratory failure (p<0.001), acute respiratory distress syndrome (p<0.001), and air-leak syndrome (p<0.001) compared to non-PB patients. Conventional treatment including the use of neuraminidase inhibitors and antibiotics did not differ between the PB and non-PB patients, but PB patients required more anti-inflammatory treatment (p=0.019) and ventilator support (p<0.001). Combined univariate and multivariate analyses suggested that radiographic findings, including mediastinal emphysema (p=0.012) and lung consolidation (p=0.012), as well as increased levels of neutrophils (p=0.026), aspartate aminotransferase (p=0.004), and lactate dehydrogenase (p<0.001), were identified as risk factors for PB development in patients with influenza virus pneumonia. Although PB patients required more intensive care and had longer hospital stays, they all recovered well after treatment. Conclusion Influenza virus infection is linked to PB development in children. Identifying risk factors and early intervention such as bronchoscopy can improve the prognosis of children with PB.

Abstract
Plastic bronchitis (PB) is a severe acute respiratory disease that develops as a result of the formation of branching mucus plugs in the bronchial tree. PB is known as a complication of influenza A virus infection, but some cases have been associated with influenza B virus infections. This patient was a 3-year-old boy with no history of allergic disease who developed PB requiring ventilator management after influenza B virus infection. He was hospitalized and managed with ventilator support because of acute respiratory failure. Influenza B virus infection was diagnosed via rapid antigen test and real-time reverse-transcription polymerase chain reaction (RT-PCR). A bronchoscopy performed after a chest X-ray and computed tomography confirmed the presence of extensive atelectasis in the right lung field and mucus plugs in the right bronchus. The patient’s respiratory condition improved rapidly after removal of the plugs. Quantitative real-time RT-PCR performed with nasal and aspirated sputum samples obtained at hospitalization revealed a higher viral RNA load in the upper rather than in the lower respiratory tract. Viral replication in the lower respiratory was not found to be a major contributor toward mucus plug formation. The finding of increased serum IgE in the absence of a history of allergic disease suggests that an allergic reaction contributed to the formation of mucus plugs.

Abstract
Plastic bronchitis is a rare, underdiagnosed and potentially fatal condition. It is characterised by the formation and expectoration of branching gelatinous plugs that assume the shape of the airways. These airway plugs differ from the allergic mucin that characterises allergic bronchopulmonary aspergillosis and mucoid impaction of the bronchi. Plastic bronchitis is most often encountered in the paediatric population following corrective cardiac surgery, such as the Fontan procedure. It also occurs in adults. Plastic bronchitis in adults is rare, heterogeneous in its aetiology, and can lead to respiratory distress or even life-threatening airway obstruction. Plastic bronchitis in adulthood should not be overlooked, particularly in patients with chronic inflammatory lung diseases. This review presents current understanding of the presentation, aetiology, pathogenesis, pathology and management of plastic bronchitis in adults.

Abstract
BACKGROUND Plastic bronchitis (PB) is a rare, variable, and potentially fatal disease. This study aimed to assess the efficacy of fiberoptic bronchoscopy (FOB) and bronchoalveolar lavage (BAL) in treating children with PB. METHODS In total, 15 children with PB, between 2012 and 2020, were enrolled in our study. Within 12 hours of admission, FOB and BAL were performed and reviewed under local anesthesia and sedation. Before and after FOB, clinical findings and chest imaging were evaluated. RESULTS Regarding the onset of symptoms before FOB, all cases had prominent cough for 7.00 ± 4.55 days, and 14 had persistent high fever. In total, 13 cases had complete obstruction from bronchial casts, consistent with consolidated lesions; 2 had partial airway obstruction. Within 3 days, complete resolution was revealed in nine cases. Overall, six cases underwent repeated FOB (range, 2-3 times) for persistent atelectasis and airway obstruction. Except for two cases with type 2 PB, cast histology confirmed type 1 PB for all cases. Only eight children had minor intra- and post-procedure complications. Reverse transcription-polymerase chain reaction for Mycoplasma pneumoniae in sputum and BAL samples were positive in 13 cases. Next-generation sequencing of the BAL samples was positive for adenovirus and Human parainfluenza virus in one case, respectively. During 1 month to 7 years of follow-up, no patient developed PB recurrence, asthmatic attacks, or chronic cough. CONCLUSIONS Early FOB and BAL were effective in alleviating clinical findings, atelectasis, and airway obstruction. Serial FOB could be performed in patients with recurrent symptoms.

Abstract
Introduction The aim of this study was to evaluate the severity of hematological findings according to etiology in patients with pancytopenia and bicytopenia. Methods Patients with bicytopenia and pancytopenia who were examined in Diyarbakir Children Hospital Pediatric Hematology and Oncology clinic between June 2017-June 2018 were evaluated retrospectively. Results Of the 130 patients included in the study, 73 (56.2%) were male and 43 (43.8%) were female. The mean age of the patients was 4.9 ± 4.86. Forty-five (34.6%) patients had pancytopenia and 85 (65.3%) had bicytopenia. The youngest patient was 1-month old and the oldest patient was 18-year-old. The mean blood count parameters were white blood cell (WBC): 10.207 ± 39.781, neutrophil: 1515 ± 1418, hgb: 9.3 ± 2.3, mean corpuscular volume (MCV): 80 ± 13.1, platelet: 118.823 ± 93.645. Three out of 130 patients had hyperleukocytosis (WBC > 50.000/mm3). Vitamin B12 deficiency was detected in 35 patients. When patients with primary hematological disease were compared with patients with secondary causes of cytopenias, a significant difference was found in terms of leukocyte count, hemoglobin level, MCV elevation, and low platelet count. Conclusion The determination of the severity of cytopenias in differential diagnosis may be useful in distinguishing primary hematological diseases from secondary causes of pancytopenia and bicytopenia. However, vitamin B12 deficiency in developing countries is one of the most important causes of public health as well as in the etiology of pancytopenia and bicytopenia.
