Background: A secondary spontaneous pneumothorax is a complication of an underlying pulmonary disease. In recent years, there have been only a few scattered reports of patients with silicosis also having a pneumothorax. Silicosis, a form of disabling pulmonary fibrosis, is a well-known occupational disease resulting from high-level exposure to silica or silica-containing dusts. The objective of the present study was to elucidate any associations between the occurrence of a pneumothorax, and pulmonary function tests and clinical observations performed prior to the pneumothorax; these two factors may be predictors for a pneumothorax among workers exposed primarily to silica-containing respirable dust. Methods: A diagnosis of silicosis was made on several factors: silica dust exposure, appropriate interval of time after exposure, clinical findings, pulmonary function tests and chest radiological findings. A checklist was designed for collecting data of occupational history, respiratory signs, and symptoms from onset of dust exposure to the occurrence of a pneumothorax. Spirometery was conducted in accordance to the recommendations of standard protocols and guidelines posited by the American Thoracic Society. Autopsies were performed in three cases where the patient had suffered a pneumothorax due to silicosis. Mann—Whitney U-tests and Fisher's exact tests were used to determine any associations between pneumothorax and predictor factors. Results: An association between a progressive decrease in pulmonary function test values and a pneumothorax was observed. The occurrence of a pneumothorax was associated with complaints of pleuretic chest pain, resting dyspnea, respiratory distress, paroxysmal nocturnal dyspnea, orthopnea and crackle. Conclusion: A characteristic decline in pulmonary function test values and the severity of respiratory impairment may facilitate the occurrence of a pneumothorax in silicosis.

Background: Spirometry is a universal, simple, and non-invasive pulmonary function test. Spirometry, along with calculation of the forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), is helpful for diagnosing obstructive or restrictive lung disease. Postoperative Pulmonary Complications are defined as unintended pulmonary abnormalities that occur as a result of surgery which cause identifiable dysfunction. Purpose: To find the evidence showing the importance of pre-operative PFT to predict risk of pulmonary complications after abdominal surgery Methodology: The study was conducted according to Preferred Reporting Items for systematic reviews and meta-analysis guidelines. Evidences selected since year 2002- 2020 from PubMed, Google Scholar, Physiotherapy Evidence Database (PEDro), ResearchGate and ScienceDirect. Key words used were: Pulmonary Function Tests, Post-Operative Pulmonary Complications, and Abdominal Surgery. Analysis was done using 2 scales: Centre for Evidence-Based Medicine Levels of Evidence Scale. Total 12 articles were found. Among them 10 were selected. Results: 5 articles showed that preoperative PFT is important in prediction of PPCs while the other half concluded that routine preoperative spirometry is not necessary before non-thoracic surgeries. Conclusion: Based on evidences, in the nutshell it is reviewed that there is controversy regarding the value of preoperative pulmonary functions test in non-thoracic surgeries. Keywords: Pulmonary Function Tests, Post-Operative Pulmonary Complications, and Abdominal Surgery

Introduction: Allergic Rhinitis and Asthma adversely affects height in children and it could be considered as an objective tool to assess severity, compliance and lung functions in children. We studied the correlation between height and pulmonary function tests with classification of allergic rhinitis and asthma. Aims & Objectives: 1) To study the height parameter with the grade of asthma and allergic rhinitis 2) To evaluate the pulmonary function test with the severity of asthma and allergic rhinitis 3) To correlate height and pulmonary function test with the classification of asthma and allergic rhinitis. Material and Methods: A prospective study including 30 patients in the age group of 5-12 years diagnosed with allergic rhinitis (AR) and bronchial asthma was conducted in a private tertiary care hospital in Navi Mumbai. History was entered in a pre-designed proforma and height was measured using a calibrated stadiometer along with pulmonary function tests recorded at the initial and two visits, 3 months apart. Results: Height increased significantly in patients without AR (p-value<0.01), with mild intermittent (p-value=0.02) and mild persistent AR (p-value<0.01) on subsequent visits. Patients with intermittent, mild persistent and moderate persistent asthma showed a statistically significant increase in height (p-value<0.01) with subsequent assessments. No significant increase in height was noted in patients with moderate persistent AR (p-value=0.14) and severe persistent asthma (p-value=0.16). At baseline, the height correlated significantly with FEV1 (p value<0.01), FVC (p value<0.01), Pre and Post-PEFR (p value<0.01, each). This trend continued at the first follow up. At the second follow-up, height correlated significantly with all parameters of pulmonary function tests (p value<0.01 for FEV1, FVC, FEV1/FVC ratio and PEFR). Conclusion: Height correlation with classification of AR and Asthma along with pulmonary function test has emerged as a simple, safe, cost-effective method in assessing control and monitoring the disease.

Objective: We aimed to evaluate our patient’s treatment responses to three-month immunotherapy for allergic rhinitis with or without asthma, and to investigate the factors affecting treatment Material and Methods: A total of 53 patients receiving subcutaneous immunotherapy for allergic rhinitis with or without asthma were included in the study. All patients were positive for mite skin prick test. Asthma was present as a concomitant disease in 28(52.8%) patients. Patients with and without asthma were classified in two groups as “Allergic rhinitis + Asthma+” and “Allergic rhinitis+ Asthma-“. The values of pulmonary function tests of all patients, and in rhinitis with asthma patients, the Asthma Control Test scores before and after three months of treatment were recorded. Results: In “Allergic rhinitis + Asthma+” and “Allergic rhinitis + Asthma-“groups, male/female ratio was 7/21 and 10/15, mean age was 33±9 and 32±9 years. No statistically significant differences were present between the pre-treatment and 3-month-treatment values of pulmonary function test. The difference between the pre-treatment and 3-month treatment asthma control test scores was strongly significant. Conclusion: In allergic rhinitis, which is quite commonly associated with asthma, the control of asthma is also provided with the treatment of allergic rhinitis. By using pulmonary function test in allergic rhinitis and asthma control test in asthma, we showed that the effectiveness of allergen specific immunotherapy started in 3 months which was earlier from current literature.

Pulmonary Function Tests are one of the prime tool to evaluate respiratory symptoms and diagnose disease. It is also used for functionality and preoperative risk evaluation.Many organizations, including the National Asthma Education and Prevention Program, Global Initiative for Chronic Obstructive Lung Disease (GOLD), and American Thoracic Society (ATS), recommend using these tests.(1–3)When added to correlate with clinical history. Pulmonary Function Test have an high accuracy in predicting the diagnosis and further management of the patient. Pulmonary function test assesses the integrated mechanical function of the lung, chest wall, respiratory muscles, and airways and is valuable tool in evaluating patients with respiratory symptoms

A multicentre, cross-sectional study was carried out in six centres across Canada to establish a national standard for pulmonary function tests using healthy, lifetime nonsmokers, with each centre aiming to test 10 men and 10 women from each decade from 20 to 80 years of age. Data from each centre were used to derive prediction equations for each centre, and pooled data from all centres (total: 327 women and 300 men) were used to derive Canadian predicted equations. The predictive models were compared with three widely used published models for selected tests. It was found that, in general, the equations modelled for each centre could be replaced by the models obtained when pooling all data (Canadian model). Comparisons with the published references showed good agreement and similar slopes for most tests. The results suggest that pulmonary function test results obtained from different centres in Canada were comparable and that standards currently used remain valid for Canadian Caucasians.

Background Patients with a mediastinal mass are at risk for cardiorespiratory complications in the perioperative period. The authors' objectives were to evaluate the incidence of life-threatening intraoperative cardiorespiratory and postoperative respiratory complications in adult patients and to study the usefulness of clinical signs and symptoms, radiologic evaluation, and pulmonary function tests in the determination of the perioperative risk. Methods The authors reviewed the investigation and treatment of adult patients presenting with anterior or middle mediastinal masses for surgery under anesthesia between January 1994 and July 2000. Results Ninety-eight patients underwent 105 anesthetic cases. The incidences of intraoperative cardiorespiratory and postoperative respiratory complications were 4 in 105 and 11 in 105, respectively. No collapse of the airways occurred during anesthesia. However, a high incidence of early postoperative life-threatening respiratory complications was observed (7 in 105). In a multivariate logistic regression analysis model, perioperative complications were predicted by the occurrence of cardiorespiratory signs and symptoms at the initial presentation (odds ratio [OR], 6.2) and the presence of combined obstructive and restrictive patterns (mixed pulmonary syndrome) on pulmonary function tests (OR, 3.9). Intraoperative complications were associated with pericardial effusion on computed tomography scan (OR, 19.8). Postoperative respiratory complications were related to tracheal compression of more than 50% on preoperative computed tomography scan evaluation (OR, 7.4) and mixed pulmonary syndrome on pulmonary function tests (OR, 15.1). Conclusion Obstruction of the airway in an adult with a mediastinal mass is a rare event in the intraoperative period. Nevertheless, caution should be observed for the occurrence of early postoperative life-threatening respiratory complications. Patient at high risk of perioperative complications can be identified by the occurrence of cardiopulmonary signs and symptoms at presentation, combined obstructive and restrictive pattern on pulmonary function tests, and computed tomography scan findings (tracheal compression &gt; 50%, pericardial effusion, or both).

Aim: The aim of the study was to determine the effect of intermaxillary xation on pulmonary function. Methods:133 patients comprising 107 males and 26 females with age ranging from 18 to 50 were taken up for study. The patients' Pulmonary Function Tests were done using spirometer to measure the necessary parameters before and after the application of intermaxillary xation. The values obtained were also compared with 50 healthy volunteers. Results: The results showed that there is a signicant decrease in values of Pulmonary Function Test after the application of intermaxillary xation. Conclusion: Pulmonary status evaluation becomes necessary on account of the obstructive nature of intermaxillary xation. This simple and routinely used procedure should be avoided in respiratory compromised patients with Pulmonary Function Test values lower than the predicted value.
