Has the Coronavirus Disease 2019 Pandemic Played a Role in the Early Detection of Pulmonary Embolism in Children?

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.

Surgery versus conservative management in congenital lobar emphysema: follow up and indicators for surgery.

INTRODUCTION: Congenital lobar emphysema (CLE), a rare developmental lung malformation, involves the hyperaeration of one or more lung lobes caused by partial obstruction and occurs at a rate of 1/20,000-30,000 live births. Here, we aimed to retrospectively examine the clinical, radiological, and bronchoscopy findings of patients with CLE who were diagnosed and treated by surgical or non-surgical (conservative) approaches at our center and compared our results with those in the literature. METHODS: We examined the clinical, radiological, and bronchoscopy findings of 20 patients with CLE aged 0-18 years at our center between 2013 and 2020. In addition, we examined the symptoms and findings recorded during the patients' follow-up in this retrospective descriptive study. RESULTS: The median age of 20 patients with CLE at diagnosis was 3.2 years (range 1 day-17 years). Respiratory distress and mediastinal shift were more prominent in patients who underwent surgery, and they were diagnosed at an earlier age compared with patients who were followed up conservatively (p = 0.001, 0.049, 0.001, respectively). Neither the pulmonary lobe involvement nor the bronchoscopy findings were found to be indicative of surgery. DISCUSSION: We observed that respiratory distress and mediastinal shift were more prominent in patients with a diagnosis of CLE who underwent surgery compared with patients who were conservatively followed up. Moreover, we observed that those who underwent surgery were diagnosed with CLE at an earlier age. In line with the literature, the pulmonary symptoms and CLE-related imaging findings in our study were reduced during conservative follow-up.

Health-related Quality of Life for Children With Leukemia: Child and Parental Perceptions.

BACKGROUND: The importance of health-related quality of life (HRQoL) in patients with acute lymphoblastic leukemia (ALL) has increased in recent years. This study aimed to assess HRQoL in children with ALL, affecting factors, and the relationship between parent proxy-report and child self-report HRQoL. MATERIALS AND METHODS: A total of 59 children and their parents (both mother and father) were enrolled in this cross-sectional study. Turkish version of the Pediatric Quality of Life Inventory (PedsQL) 3.0 Cancer Modules were used to determine HRQoL. RESULTS: According to subscales of the self-report form, nausea and operational anxiety scores differed significantly by the treatment status; communication score varied considerably by the hospitalization length of stay; pain and hurt, cognitive problems, and perceived physical appearance scores differed significantly by the maternal chronic disease status (P<0.05). The presence of maternal chronic disease was significantly related to the total score of the parent-proxy report (mother) (P<0.05). There was a moderate correlation between total scores of child and mother (P<0.05, r=0.419) but not with the father. CONCLUSION: Children on-treatment had significant problems in nausea and procedural anxiety subscales; however, children who were hospitalized more had fewer issues in the communication subscale. Also, children whose mother had chronic disease had poorer HRQoL regarding pain and hurt cognitive problems and treatment anxiety. Given the importance of assessment and monitoring HRQoL in children with ALL, health professionals should be aware of how parents' chronic disease affects HRQoL. Psychosocial support should be provided to children and their parents, especially for those whose parents have a chronic illness.

Experience of flexible bronchoscopy in the pediatric pulmonary diseases clinic.

Introduction: Flexible bronchoscopy is a valuable method in the diagnosis and treatment of respiratory tract diseases in children. This study aimed to examine the indications for and results of flexible bronchoscopy in children. Materials and Methods: The study included patients aged 0-18 years who underwent flexible bronchoscopy between 1 January 2017 and 31 December 2022. The patients were evaluated for demographic characteristics, indications for bronchoscopy, comorbidities, bronchoscopy findings, and the results of bronchoalveolar lavage. Result: During the defined study period, a total of 410 flexible bronchoscopy procedures were performed. 51.9% of the patient population were male, and 48.1% were female, with a mean age of 96.93 ± 63.45 months. The most common indication for flexible bronchoscopy was recurrent lower respiratory tract infection (26.8%), followed by chronic cough (19.1%). The bronchoalveolar lavage culture results showed that the most commonly isolated microorganisms were H. influenzae non-type b (7.8%) followed by M. catarrhalis (7.3%). Mucus obstruction and secretion (33.0%) constituted the most common bronchoscopic findings, while the flexible bronchoscopy examination was normal in 27% of patients. No serious complications occurred in any patient during or after the procedure. Conclusions: The results of this study demonstrated that the most common indication for flexible bronchoscopy was recurrent lower respiratory tract infection and the most common bronchoscopy finding was purulent secretion with mucus obstruction. Flexible bronchoscopy is an important diagnostic and treatment tool for patients with recurrent respiratory symptoms. It is a highly valuable method as it enables direct visualization of the airways and facilitates the collection of bronchoalveolar lavage samples.

Clinical radiological and pathological staging of children with hypersensitivity pneumonitis.

OBJECTIVE: Hypersensitivity pneumonitis (HP) is rare in the pediatric population. To date, there are no studies defining a correlation between clinical, radiological, and pathological findings in children with HP. The objective of this study is to define the clinical, and radiological characteristics and prognosis of childhood HP and to examine the clinical, radiological, and pathological correlation between HP stages. METHODS: Patients with suspected HP and followed at two tertiary care hospitals between 2000 and 2020 were retrospectively evaluated. Computed tomography (CT) of the chest of patients was evaluated by a single radiologist. The interagreement between clinical and radiological severity of the patients was calculated with the κ test. RESULTS: Fourteen children with suspected HP were identified. The results of 10 patients with the definitive diagnosis were as follows: one patient (10%) had acute, five patients (50%) had subacute, and four patients (40%) had chronic HP. The most prominent findings in chest CT were hilar, or hilar and subcarinal lymphadenopathy (80%), centrilobular nodules (60%), patchy or diffuse ground-glass opacities (50%), and cysts (50%). The interagreement between clinical and radiological severity of the patients was 100% (approximate significance: 0.003). The diagnosis of four patients with suspected HP who were unresponsive to standardized medical treatments or developed multisystem involvement was diagnosed with other diseases. One patient (10%) with definitive chronic HP died due to respiratory failure during follow up. CONCLUSION: Similar to adult HP, the prognosis is worse in children with existing fibrotic equivalents in chest CT. Patients who are not responding to standard medical treatments or develop multisystem involvement should be evaluated for other lung diseases.
