RESUMEN
BACKGROUND: The decline in pulmonary function is a predictor of disease progression in patients with cystic fibrosis (CF). This study aimed to determine the decline rate of percent predicted forced expiratory volume in 1 s (ppFEV1) based on the data of the CF Registry of Turkey. The secondary aim was to investigate the risk factors related to the decline in ppFEV1. METHODS: A retrospective cohort study of CF patients over 6 years old, with pulmonary function data over at least 2 years of follow-up was extracted from the national CF registry for years 2017-2019. Patients were classified according to disease severity and age groups. Multivariate analysis was used to predict the decline in ppFEV1 and to investigate the associated risk factors. RESULTS: A total of 1722 pulmonary function test results were available from 574 patients over the study period. Mean diagnostic age was older and weight for age, height for age, and body mass index z scores were significantly lower in the group of ppFEV1 < 40, while chronic Pseudomonas aeruginosa (p < .001) and mucoid P. aeruginosa colonization (p < .001) were significantly higher in this group (p < .001). Overall mean annual ppFEV1 decline was -0.97% (95% confidence interval [CI] = -0.02 to -1.92%). The mean change of ppFEV1 was significantly higher in the group with ppFEV1 ≥ 70 compared with the other (ppFEV1 < 40 and ppFEV1: 40-69) two groups (p = .004). Chronic P. aeruginosa colonization (odds ratio [OR] = 1.79 95% CI = 1.26-2.54; p = .01) and initial ppFEV1 ≥ 70 (OR = 2.98 95% CI = 1.06-8.36), p = .038) were associated with significant ppFEV1 decline in the whole cohort. CONCLUSIONS: This data analysis recommends close follow-up of patients with normal initial ppFEV1 levels at baseline; advocates for early interventions for P. aeruginosa; and underlines the importance of nutritional interventions to slow down lung disease progression.
RESUMEN
OBJECTIVE: Pulmonary embolism (PE) poses a significant threat to children, and nonspecific symptoms lead to delayed diagnosis. The emergence of coronavirus disease 2019 (COVID-19) has increased the complexity as it is associated with similar symptoms and increased risk of thrombotic complications. This study aimed to assess the risk factors, clinical presentations, and diagnostic features of PE in pediatric patients and to examine the impact of the COVID-19 pandemic on children with PE. MATERIALS AND METHODS: We conducted a retrospective descriptive study examining the clinical and diagnostic data of 44 pediatric patients with radiologically confirmed PE. The study compared and analyzed patients diagnosed before and during the COVID-19 pandemic. RESULTS: In the study, 21 of 44 pediatric patients were diagnosed in the 4 years before the COVID-19 pandemic, and 23 were diagnosed with PE during the COVID-19 pandemic. The mean time to diagnosis was 8 (2 to 14) days before the pandemic and 1 (1 to 2) days during the pandemic ( P < 0.001). The most common associated condition in both groups was infection (65.9%). Dyspnea (65.9%) and tachypnea (50.0%) were common symptoms. Except for deep vein thrombosis, there were no significant differences according to associated conditions between the groups ( P = 0.001). Pulmonary emboli were anatomically detected using computed tomography angiography, showing bilateral involvement in 45.4% of patients, segmental artery involvement in 38.6%, and main artery involvement in 15.9%. CONCLUSION: The COVID-19 pandemic heightened suspicion of pediatric PE and accelerated diagnosis. Standardized diagnostic guidelines are increasingly necessary to balance accurate diagnosis with avoiding excessive imaging.

BACKGROUND AND AIM: Flexible bronchoscopy (FB) poses a risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission due to aerosol generation. This study aimed to assess the utilization, indications, outcomes, and safety of FB in pediatric patients for noncoronavirus disease of 2019 (COVID-19) reasons during the pandemic. MATERIALS AND METHODS: We retrospectively analyzed pediatric patients who underwent FB for non-COVID-19 indications at a tertiary children's hospital's pulmonary clinic during the COVID-19 pandemic. Patients showed no COVID-19 symptoms and tested negative for SARS-CoV-2 by real-time polymerase chain reaction (PCR) of nasopharyngeal and throat swabs within 24 h before the procedure. FBs were conducted in the operating room, with healthcare professionals (HCPs) wearing personal protective equipment, including medical N95 masks, gloves, gowns, and eye protection. RESULTS: Between March 2020 and April 2022, 167 pediatric patients underwent FB for non-COVID-19 indications. Common indications included foreign body aspiration (22.7%), stridor (10.1%), and atelectasis (8.9%). No COVID-19 symptoms were observed in patients on the 1st and 10th days post-FB. During the 1-month follow-up, 52 patients underwent SARSCoV-2 PCR testing, and one patient tested positive in the third week after the procedure. None of the HCPs in the FB team experienced COVID-19 symptoms or tested positive for SARS-CoV-2. CONCLUSION: A bronchoscopy protocol with safety precautions minimized the risk of COVID-19 transmission, allowing safe FB performance for non-COVID-19 indications in pediatric patients during the pandemic. The experience gained in FB during COVID-19 is valuable for similar situations in the future.

INTRODUCTION: Biologic modifying agents are associated with an increased risk for infection with mycobacteria. The aim of this study is to document patients who received different biologic modifying therapies in our pediatric rheumatology department and the possibility of development of tuberculosis (TB). METHODOLOGY: This retrospective study was conducted in Ankara City Hospital. Pediatric patients who were treated with biologic modifying agents between 2010-2020 were documented. Development of TB and the risk factors were assessed in this patient group. RESULTS: There were 72 patients who were treated with different biologic modifying agents. Tuberculin skin test (TST) was positive in 7 (9.7%) patients during follow up. Three patients whose TST was positive had received canakinumab, 2 received etanercept, 1 received adalimumab and 1 received anakinra. Median duration of therapy was 43.5 (16.5-168) months for these patients and the duration was longer than patients who did not develop latent tuberculosis (p = 0.04). Patients who developed latent TB under treatment were significantly older than the patients who did not (p = 0.01). CONCLUSIONS: According to our findings, 9.7% of pediatric patients who received biologic modifying agent therapy developed latent TB. Patients who developed latent TB were older, and the duration of treatment was longer than patients who did not develop latent TB. Although not statistically significant, canakinumab, which is known as an agent less likely to cause TST conversion, was in fact the most common agent that caused TST conversion.
