Abstract Background. Plastic bronchitis (PB) is a pulmonary disease characterized by the formation of bronchial casts (BCs) that lead to airway blockage. The study aimed to investigate the clinical features of PB related to respiratory tract infection. Methods. A retrospective analysis was performed on data collected over a 5-year period (from January 2015 to December 2019) on children with PB (n=269). The clinical manifestations, laboratory data, imaging findings and management, were investigated. The single fiberoptic bronchoscopy (FOB, n=144) and multiple-treatment groups (n=125) were compared.Results. A total of 269 PB children were included with a mean age of 6.7 ± 2.8 years. The majority of cases (n=241, 89.6%) were diagnosed with Mycoplasma pneumonia (MP) infection. The mean duration of fever and hospitalization was 10.6 ± 3.7 and 9.3 ± 3.2 days, respectively. All patients presented with cough and fever, 62 (23.0%) suffered from hypoxemia, and 144 (53.5%) had extrapulmonary complications. Higher levels of ESR, CRP, PCT, IL-6, LA, LDH, FER and D-dimer were observed. CT findings, including pulmonary consolidation, segmental or lobar atelectasis, pleural effusion and pleural thickening, were observed in 97.4%, 46.5%, 47.9% and 63.2% of cases, respectively. Furthermore, multivariate logistic regression analysis showed that N% >75.5%, LDH >598.5U/L, and D-dimer>1.2mg/L were independent risk factors for multiple therapeutic FOB. Conclusions. MP is a major pathogen responsible for PB in children. Patients with PB are more likely to experience persistent fever and excessive inflammation and have severe radiological findings. FOB is an effective treatment for patients with PB, and children may require multiple FOBs for cast removal. N% >75.5%, LDH >598.5U/L and D-dimer > 1.2mg/L are independent predictors of multiple FOB treatment.

Objective: To compare the efficacy of total laryngeal anesthesia and simple local anesthesia during awake fiberoptic bronchoscopy. Study Design: Quasi-experimental study. Place and Duration of Study: Department of Pulmonology, Combined Military Hospital Lahore, from Jan to Jul 2020. Methodology: A total of 70 patients, who were undergoing fiberoptic bronchoscopy were divided into two groups. Group-I patients were given topical anesthesia with 2% Lignocaine while group-II patients, in addition to topical Lignocaine, had 2% Lignocaine injected into bilateral internal laryngeal nerves for total laryngeal anesthesia. Assessment of efficacy of anesthesia was evaluated by Reasoner scale. Results: In group-I, 26 (74.28%) patients showed mild or moderate cough and gagging during stage-1. Fifteen (42.85%) patients showed moderate cough and gagging that interfered with the procedure during stage-2 and 19 (54.28%) patients showed mild cough or gagging that did not interfere with the procedure in stage-3. In group-II, 17 (48.57%) patients exhibited mild cough or gagging during stage-1. Sixteen (45.71%) exhibited mild cough or gagging that did not interfere with the procedure during stage-2 with all the patients showing either no cough or mild cough and gagging that did not interfere with the procedure during stage-3. More patients of group-II 32 (91.42%) agreed to a repeat test if required medically as compared to group-I 28 (80%). Conclusion: Patients undergoing fiberoptic bronchoscopy who underwent total laryngeal anesthesia and sedation, in addition to topical anesthesia experienced less cough and gagging than those receiving only local anesthesia.

Plastic bronchitis (PB) is a rare and potentially fatal disease characterized by acute progressive dyspnea caused by bronchial casts in the bronchial tree. We analyzed two children with asthma and PB who presented with high fever, cough and dyspnea. Both cases showed acute onset and rapid disease progression. Laboratory examination revealed that both children were infected with influenza A virus. Emergency fiberoptic bronchoscopy was performed within 20 hours of admission. Immediately after removing the bronchial casts, their dyspnea symptoms improved significantly, and they recovered after comprehensive treatment with antiviral drugs, antibiotics and glucocorticoids. When children with asthma have acute progressive and difficult-to-relieve dyspnea after infection with influenza A virus, clinicians should be aware of the possibility of PB and perform bronchoscopy as soon as possible to facilitate early diagnosis and treatment and improve patient prognosis.

Background: To determine the predictive value of peripheral blood cell parameters for refractory Mycoplasma pneumoniae pneumonia (RMPP) in children over 6 years old.Methods: A retrospective study was conducted in children with RMPP admitted to the respiratory department of Tianjin Children's Hospital from September 2017 to September 2019, and non-refractory Mycoplasma pneumoniae pneumonia (NRMPP) was selected by the propensity score method and matched according to the ratio of 1:1.5. We analyzed the differences in clinical characteristics, peripheral blood cell parameters, imaging findings, and treatments between the two groups, and further determined the predictive value of peripheral blood cell parameters on RMPP.Results: There were 76 patients in the RMPP group and 114 patients in the NRMPP group. We found that the RMPP group has a longer clinical course and a higher incidence of intrapulmonary and extrapulmonary complications (p < 0.01). Moreover, the proportion of children in the RMPP group who received immunotherapy (such as glucocorticoid, gamma immunoglobulin) and fiberoptic bronchoscopy intervention was higher than that in the NRMPP group (p < 0.01). Meanwhile, the level of neutrophil, neutrophil/lymphocyte ratio (NLR), platelet count/lymphocyte ratio (PLR), mean platelet volume/lymphocyte ratio (MPVLR), C-reactive protein (CRP), lactic dehydrogenase (LDH), and interleukin (IL)-6 in the RMPP group was significantly higher (p < 0.01) than those in the NRMPP group. The incidence of pulmonary consolidation, atelectasis, and pleural effusion was also higher in the RMPP group (p < 0.05). ROC curve and binary logistic regression analysis showed that NLR > 3.92 (OR = 3.243; 95% CI = 1.485–7.081; p = 0.003), MPVLR > 5.29 (OR = 2.700; 95% CI = 1.258–5.795; p = 0.011), and pleural effusion (OR = 3.023; 95% CI = 1.424–6.420; p = 0.004) were significant factors in predicting RMPP. Our study showed that NLR had higher accuracy in predicting RMPP than CRP.Conclusions: The parameters of peripheral blood cells might be a predictor of RMPP. NLR > 3.92, MPVLR > 5.29, and pleural effusion might have important predictive value for RMPP in children over 6 years old.

Fiberoptic bronchoscopy (FOB) is one of the important modalities in helping to uphold the diagnosis and stadium of bronchogenic carcinoma. However, FOB has some limitations, namely invasive, time-consuming, requiring sedation, intolerable in patients who are critically ill, and difficult to evaluate distal airway side of severe stenosis. To identify the imaging capability of virtual bronchoscopy (VB) examinations in evaluating abnormalities in the tracheobronchial in bronchogenic carcinoma. Observational study with total sampling. Data was obtained from the histopathologic with diagnosis of bronchogenic carcinoma in 1 year. Retrospectively, the data were obtained from the archives of thoracic CT examinations in Radiology and FOB examination in Lung Operating Room. The variables assessed were the finding of mass of endobronchial based on its location, the main bronchi constriction, lobar bronchi constriction, segmental bronchi constriction, and compression/tracheal deformity. The results of VB were examined by three radiologists independently and were then compared with the results of FOB. The observation results of VB and FOB were used to analyse the degree of conformity. There is a low level of agreement on the finding of endobronchial mass, lobar bronchi and segmental bronchi constriction, sufficient level of agreement on the main bronchial constriction finding. VB has a limited capacity to evaluate abnormalities of the tracheobronchial compared with FOB, but VB has an advantage in evaluating the patency of the distal airway of severe obstruction.

Abstract Background Pulmonary toxicity due to chemotherapeutic agents can occur with many established and new drugs. Strong clinical suspicion is important as the clinical presentation is usually with nonspecific symptoms like cough, dyspnea, fever, and pulmonary infiltrates. Timely discontinuation of the offending agent alone can improve the condition. Methods A prospective observational study on patients receiving chemotherapy at an 800-bedded tertiary care hospital was performed from 2014 to 2016. Consecutive patients on chemotherapy, presenting with nonresolving respiratory symptoms were evaluated with contrast-enhanced computerized tomography of chest, diffusion lung capacity for carbon monoxide (DLCO), fiberoptic bronchoscopy with lavage, and biopsy, after excluding all causes for pulmonary infections. Descriptive data has been depicted. Results A total of 18 patients were evaluated for persistent symptoms of dry cough, dyspnea, and fever among 624 who received chemotherapy during the study period. Ground-glass opacities on high-resolution CT was the most common imaging finding, others being patchy subpleural consolidation and pleural effusion. Lymphocyte-predominant bronchoalveolar lavage was detected in nine. Eight of the 15 patients who underwent DLCO, had abnormal results. Seven had significant histopathological findings on bronchoscopic lung biopsy, which revealed organizing pneumonia as the most common pattern. Paclitaxel, fluorouracil, gemcitabine, and tyrosine kinase inhibitors were the common culprit drugs. Discontinuation alone of the culprit drug was effective in 15 and 3 needed oral corticosteroids for relief of symptoms. None of the patients died due to the toxicity. Conclusion An incidence of 2.8% for chemotherapy-induced lung injury was seen in our observational study of 3 years, with parenchymal, interstitial, and pleural involvement due to various chemotherapeutic agents. Oral steroids maybe required in a subset of patients not responding to discontinuation of the culprit agent.
