Introduction:  The diagnosis of pleural tuberculosis remains a clinical challenge due to the paucibacillary nature of disease. Medical thoracoscopy remains the gold standard in diagnosing tuberculous pleuritis.

Objective:  To establish the diagnostic yield of sago-seed thoracoscopic appearance of pleura in tuberculosis and its correlation with histopathology, tissue AFB culture and tissue Xpert MTB/Rif assay.

Objectives: To compare the diagnostic accuracy of two systems in predicting mortality among patients with acute exacerbation of chronic obstructive pulmonary disease.

Methods: The cross-sectional study was conducted from November 2017 to June 2018 in the Department of Chest Medicine, Jinnah Postgraduate Medical Centre, Karachi, and comprised patients with acute exacerbation of chronic obstructive pulmonary disease. Dyspnoea-eosinopenia-consolidation-acidaemia-atrial fibrillation system was compared with acute physiology and chronic health evaluation II scoring system after mortality scores were calculated for each patient.

Objectives: To find out the association of weight, height and age with spirometry variables and to generate a regression equation by taking weight as an independent variable beside age and height among children and adolescents of Karachi.

Methods: A modified form of ISSAC questionnaire was used. The spirometry variables recorded were Forced vital capacity (FVC), Forced expiratory volume in 1 second (FEV), FEV/FVC, Peak expiratory flow rate (PEF), Forced expiratory flow between 25% and 75% expired volume (FEF).

Background: Early diagnosis of pleural tuberculosis is difficult as it is a paucibacillary disease and a combination of tests is required to diagnose it, which have varied diagnostic accuracy and increase the cost. The aim of this study was to evaluate the diagnostic performance of the Xpert MTB/Rif assay on thoracoscopic pleural biopsy specimens.

Methods: A total of 201 patients with exudative pleural effusion and normal lung parenchyma were included in the study.

Background: The treatment of early pleural empyema depends on the treatment of ongoing infection by antimicrobial therapy along with thoracocentesis. In complicated empyema this treatment does not work and lung will not expand until removal of adhesions. The objective of the current study is to analyze the experience of management of multiloculated, exudative and fibrinopurulent empyema through rigid medical thoracoscopy under local anaesthesia and to explore new ways to manage the entity.

Objective: To determine the frequency of misdiagnosis of tuberculosis in interstitial lung disease cases.

Methods: This is a prospective study including patients registered in the interstitial lung disease clinic, Jinnah Postgraduate Medical Center, Karachi, during May-June 2017. Diagnosis of tuberculosis was only confirmed if there was any bacteriological evidence of tuberculosis at the time of diagnosis or if there was improvement in symptoms after treatment in patients diagnosed as having tuberculosis on clinical grounds.

Objective: To evaluate the effectiveness and safety of using BiPAP through endotracheal tube in comatose Chronic Obstructive Pulmonary Disease (COPD) patients with hypercapnic respiratory failure.

Methods: This is a prospective study done at Department of Chest Medicine, Jinnah Postgraduate Medical Centre, Karachi, during March to June 2017. It included all comatose COPD patients with hypercapnic respiratory failure who had a poor functional status prior to the illness and who did not meet the criteria to be kept on mechanical ventilator.
