Abstract
BACKGROUND AND OBJECTIVES The highest incidence of death in systemic sclerosis due to pulmonary disease raises the need for early detection and treatment. The study aim is the assessment of interstitial pulmonary disease by Multi Detector High Resolution CT (MDCT) and finds its relationship with the other disease parameters and the Pulmonary Function tests (PFT). PATIENTS AND METHODS A prospective cross-sectional study was performed in Assiut University Hospitals from May 2018 to January 2020 and included 62 consecutive SSc female patients. Demographic, clinical, Laboratory, PFT and MDCT assessment were conducted for all participants. RESULTS The coarseness of fibrosis was 8.32 (range 0.0-17), the average proportion of ground-glass opacification was 28.3% (range, 0.0%-75%). Honey-comb pattern was seen in (52.5%). Mean Extent of disease was 46.25±3.7 (range 5-81). Restrictive deficit found in 42 patients. Significant relation was found between the extent of disease and the percentage predicted FVC (r=0.373, p 0.018) and FEV1/FVC (r=0.593, p 0.000) and coarseness of fibrosis and proportion of ground glass opacification correlated inversely with VC (r=-0.385, p=0.014, r=-0.376, p=0.017 respectively), Rayanud's phenomena, modified Rodnan Skin Score and Medsger's general are positively correlated with MDCT disease extent. CONCLUSION Scoring of systemic sclerosis (SSc) related interstitial lung disease (SSc-ILD) could be applicable as one of the important tools for disease assessment.

Abstract
OBJECTIVE This analysis investigates any potential differences in pulmonary function test (PFT) outcomes among pediatric patients with cystic fibrosis (CF) receiving both medical management (MM) and functional endoscopic sinus surgery (FESS) versus MM alone for CF exacerbation. STUDY DESIGN Prospective cohort. SETTING Pediatric tertiary care facility. METHODS The data was prospectively collected from July 2011 to March 2020. Diagnosis of CF and age ≤ to 18 were required. All patients were hospitalized and treated for CF exacerbations with both FESS with MM and MM alone at variable time intervals, although the order of initial treatment received differed. Two-way ANOVA with repeated measures were used to determine the effect of receiving FESS with MM versus MM alone on PFT outcomes over time (during admission, at discharge, at 3 months, at 6 months, and at 12 months). RESULTS 13 pediatric patients, 7 of which had FESS with MM initially and 6 who had MM alone initially, and 20 events of both FESS and MM were included for analysis. For PFT outcomes, there was no statistically significant two-way interaction between treatment type and time following treatment, p = 0.492. The main effect of treatment did not show a statistically significant difference in FEV1 between treatment types, p = 0.737. There was no statistically significant association between treatment type and time between hospital readmission in months, p = 0.111. CONCLUSION There was no significant difference between PFT outcomes in pediatric patients hospitalized for CF exacerbation treated with MM with or without FESS at any time interval.

Abstract
Children with rheumatic disease have rare pulmonary manifestations that may cause significant morbidity and mortality. These children are often clinically asymptomatic until disease has significantly progressed, so they should be screened for pulmonary involvement. There has been recent recognition of a high mortality-related lung disease in systemic-onset juvenile idiopathic arthritis; risk factors include onset of juvenile idiopathic arthritis less than 2 years of age, history of macrophage activation syndrome, presence of trisomy 21, and history of anaphylactic reaction to biologic therapy. Early recognition and treatment of lung disease in children with rheumatic diseases may improve outcomes.

Abstract
PURPOSE E-cigarette or vaping product use associated lung injury (EVALI) has received national attention as an epidemic resulting in cases of significant morbidity and mortality. We aim to present the clinical and imaging findings in adolescents with pulmonary symptoms from suspected EVALI. METHODS Chest radiographs and CTs of adolescents (< 19 years) with acute pulmonary symptoms and history of vaping were reviewed by two radiologists in consensus. Clinical presentation and laboratory data were derived from the electronic medical records including pulmonary function tests (PFTs). RESULTS Eleven patients were identified (9 male, mean 16.6 years). The most common presentation was progressive, subacute respiratory distress with abdominal pain. All but one of the patients tested positive for tetrahydrocannabinol. Chest radiograph features were notable for interstitial pattern of opacities (91%) and basilar abnormalities (82%). CT features were notable for ground-glass opacities (89%), interstitial opacities (78%), and subpleural sparing (67%). Eight patients underwent PFTs. Six had diffusing capacity measurement, which demonstrated impaired diffusion in 3 (50%). All patients received supportive treatment with supplemental oxygen and corticosteroids. CONCLUSION Adolescents with suspected EVALI commonly present with subacute respiratory distress with abdominal pain. Imaging findings include ground-glass opacities, subpleural sparing, and basilar opacities, most consistent with organizing pneumonia or hypersensitivity pneumonitis. Recognition of the common imaging findings may have significant patient management implications, especially if the diagnosis is not suspected clinically. The lung function effects of vaping are consistent with mildly reduced airflow, which improves on follow-up testing, and reduced diffusion capacity, which, concerningly, does not improve.

Abstract
BACKGROUND The presence of widespread lung microvascular circulation and abundant connective tissue with a large reserve raises the possibility that the lung may be a target organ of the pathologic processes induced by type 2 diabetes. Pulmonary function tests (PFTs) are noninvasive medical tests that show how well the lungs are working. OBJECTIVE The aim was to compare pulmonary function tests (PFTs) and their associated factors among type 2 diabetic patients and non-diabetics at Jimma Medical Center (JMC). METHODS A comparative cross-sectional study was conducted at JMC, Jimma, Southwest Ethiopia among 298 study participants from April 1 to May 30, 2019. A face-to-face interview with semi-structured questionnaire was conducted. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), ratio of FEV1/FVC, peak expiratory flow (PEF), and forced expiratory flow (FEF25-75) were recorded by using a digital Spirometer. Independent samples t-test, simple and multiple linear regression analysis were used. RESULTS The present study indicated that means of the PFTs among type 2 diabetics were significantly reduced when compared to their matched non-diabetics (FVC (%) (m=73.7±13.8 vs m=93.8±12.3), FEV1 (%) (m=76.4±13.4 vs m=93.3±12.4), FEV1/FVC (%) (m=78.99±11.4 vs m=96.6±9.33), PEF (L/s) (m=3.91±0.28 vs m=5.03±0.35), and FEF25-75 (L/s) (m=2.89±0.75 vs m=3.39±0.82)). This study also indicated that body mass index (BMI) (β=-1.93, P<0.001) and fasting blood sugar (FBS) (β=-0.22, P<0.001) were negative predictors of FVC%. BMI (β=-1.93, P<0.001) and FBS (β=-0.29, P<0.001) were negative predictors of FEV1%. BMI (β=-1.403, P<0.001) was a negative predictor of mean FEV1/FVC. BMI (β=-1.39 P<0.001) and FBS (β=-0.15, P<0.001) were negative predictors of mean PEF (L/s). BMI (β=-0.075, P<0.001) and FBS (β=-0.075, P<0.001) were negative predictors of FEF25-75 (L/s). CONCLUSION The present study showed that there were significantly reduced mean scores of FVC, FEV1, FEV1/FVC, PEF, and FEF25-75 among type 2 diabetic patients as compared to non-diabetic participants. The FBS and BMI were independent risk factors of the PFTs among the diabetics, unlike among non-diabetic participants.

Abstract
BACKGROUND Most studies addressing the impact of hematopoietic stem cell transplantation (SCT) on pulmonary function test (PFT), and the various factors affecting that impact have been performed on the allogenic type. Few have addressed PFT changes in autologous SCT. This study describes PFT changes seen in autologous SCT recipients and addresses the various factors impacting these changes. PATIENTS AND METHODS We reviewed the medical records of 223 consecutive adult autologous SCT recipients. We collected pre-transplant and post-transplant data, as well as PFT data and long-term mortality. RESULTS A total of 123 patients with lymphoma receiving the BEAM (carmustine, etoposide, aracytin, and melphalan) conditioning regimen had a significant 5% drop in mean forced vital capacity and total lung capacity but no significant change in forced expiratory volume in one second/forced vital capacity ratio nor in diffusion lung capacity of carbon monoxide adjusted to volume. Fifteen percent of the patients with lymphoma had a clinically significant drop of 15% in their lung volume parameters. The patients with multiple myeloma receiving the melphalan conditioning regimen had no significant change in any of the PFT parameters. Smoking, baseline PFT parameters, and radiation did not affect lung function or mortality. CONCLUSIONS Autologous SCT impact on lung function depends on the disease and conditioning regimen. It leads to a drop in lung volumes but no obstruction or decrease in diffusion in patients with lymphoma receiving the BEAM regimen. Autologous SCT did not affect lung functions in patients with multiple myeloma, and these patients may not need screening PFTs.

Abstract
BACKGROUND Lung function tests reflect the underlying physiological condition of the airways and the alveoli. Therefore, they help to evaluate the respiratory health of an individual. Lung functions are compromised far before appearance of the signs and symptoms of chronic respiratory diseases. Air pollution adversely affects lung function. Exposure to sources of pollution differ between men and women due to commuting and smoking habits. The present study was carried out in Delhi to assess the association of exposure to air pollution sources with lung function of young adult females, as this younger age group is expected to have a different exposure profile than older women. METHODS The present study was conducted on the campus of a central university in Delhi among 18- to 25-year old females (n=200). A pre-tested, close-ended and interviewer-administered questionnaire was used that consisted of information on sociodemographic details of the participants and self-reported exposure to air pollution sources at the residence of participants, during their commute to and from college, and at school. Both active and passive smoking status were recorded. Lung function was assessed using a digital spirometer. RESULTS A significant association was observed between percentage of predicted value of forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) and peak expiratory flow (PEF) with the number of years the participant had resided in Delhi (p<0.05). Forced vital capacity and FEV1 of those using closed transport methods such as car, metro, and air-conditioned (A/C) bus were significantly better than those who used open transport methods such as non-A/C bus and scooter (p<0.05). Forced vital capacity and FEV1 were significantly decreased among those who had a smoke-producing factory in the vicinity of their residence (p<0.05). A significant decrease in FVC and FEV1 was observed among active smokers and among those who were exposed to passive smoking by family members in comparison to those who were not exposed (p<0.05). CONCLUSIONS The results of the present study suggest that air pollution exposure plays a role in determining the lung function profile of young adult females. This study provides baseline data on lung function of young adult females which could be used in future longitudinal cohort studies. PARTICIPANT CONSENT Obtained. ETHICS APPROVAL The study was approved by the Institutional Ethics Committee of University College of Medical Sciences. COMPETING INTERESTS The authors declare no completing financial interests.

Abstract
OBJECTIVES Idiopathic subglottic stenosis (ISGS) can have significant impacts on quality of life (QOL), but it remains unclear how patients' subjective responses correlate with objective measurement of disease severity. Peak expiratory flow percentage (PEF%) has been shown to be an effective measure of disease severity in subglottic stenosis. This study aims to identify the key QOL questions correlated with PEF% and proposes a statistical model for prediction of disease severity. METHODS Patients with ISGS presenting to an academic laryngologist were included retrospectively from 2012 to 2016. Peak expiratory flow percentage (age, sex, and height adjusted) was recorded for each visit, along with four validated QOL instruments (European QOL-Five Dimensions; RAND 36-Item Health Survey; Clinical COPD [Chronic Obstructive Pulmonary Disease] Questionnaire; and the Airway, Dyspnea, Voice, and Swallowing Summary Assessment). A stepwise multiple linear regression was used to identify statistically significant independent variables correlated with PEF%, and a model was built with these variables. RESULTS Thirty-two patients were included, with a total of 271 patient encounters. Overall scores from each of the four QOL instruments were correlated with PEF% values recorded each visit (P < 0.05). Question responses correlating most positively included overall breathlessness, difficulty catching breath, cough within the past week, dyspnea with moderate activity, perception that voice changes are restricting social life, and overall general health (all P < 0.01). A model constructed using six nonoverlapping questions yielded an adjusted R2 of 0.58. CONCLUSION Quality of life is correlated to PEF% in ISGS. Using a limited number of QOL questions, clinicians can predict objective worsening or improvement of disease severity, as measured by spirometry. LEVEL OF EVIDENCE 2b. Laryngoscope, 2017.

Abstract
OBJECTIVE AND DESIGN Sarcoidosis and idiopathic pulmonary fibrosis (IPF) are both associated with deregulated inflammatory mechanisms partially triggered by aggravated oxidative stress. 8-Isoprostane has been proposed as a reliable marker of oxidative stress, linked to several pulmonary diseases. We aimed to explore differences in 8-isoprostane levels in IPF and sarcoidosis patients, and controls. METHODS We included 16 IPF and 55 sarcoidosis patients, as well as 17 controls in the study. 8-Isoprostane levels were measured in serum and in bronchoalveolar lavage (BAL). RESULTS Serum 8-isoprostane levels were increased in all patient groups vs controls (p<0.001). The systemic 8-isoprostane concentrations were higher in sarcoidosis patients as compared to IPF subjects and controls (p=0.017 and p<0.001, respectively). IPF patients exhibited increased serum 8-isoprostane levels when compared to controls (p<0.001). Sarcoidosis patients presented significantly increased 8-isoprostane BAL levels when compared to IPF patients (p=0.002). CONCLUSION Our data indicate that the level of oxidative stress, as reflected by 8-isoprostane concentrations, is enhanced in patients with sarcoidosis, and to a lesser extent, in IPF patients when compared to controls, suggesting a potential implication of redox imbalance in both diseases.
