Section of Pulmonary & Critical Care

OBJECTIVES: To assess the Pre-bronchodilator criteria and the Post-bronchodilator criteria of FEV1/FVC ratio in diagnosing Airflow obstruction.

METHODS: An observational study was conducted from 1988 to 2006 at the Aga Khan University Hospital Patients referred to the pulmonary function test laboratory for spirometry with bronchodilator reversibility at the hospital during the above said period were enrolled. Forced spirometry was performed according to ATS guidelines. All patients who had pre-bronchodilator criteria of airflow obstruction were analyzed and compared with the post bronchodilator criteria.

RESULTS: A total of 4222 individuals underwent spirometry out of which 4072 individuals were studied. Using the pre …

Section of Pulmonary & Critical Care

Hughes-Stovin Syndrome (HSS) is a very rare clinical disorder characterized by thrombophlebitis and multiple pulmonary and/or bronchial aneurysms. Less than 40 published cases of HSS have been described in English medical literature so far. The exact etiology and pathogenesis of HSS is unknown, possible causes include infections and angiodysplasia. HSS has also been considered as a variant of Behcet's disease (BD). Patients with HSS usually present with cough, dyspnea, fever, chest pain and haemoptysis. The management of HSS can either be medical or surgical. Medical management includes the use of steroids and cytotoxic agents. Cyclophosphamide, in particular, is a favored …

Negative Pressure Pulmonary Oedema: A Rare Complication Following General Anaesthesia, Zeeshan Waheed, Javaid Khan

Section of Pulmonary & Critical Care

An important cause of pulmonary oedema is Negative Pressure Pulmonary Oedema (NPPE) which characteristically develops soon after extubation from an endo-tracheal intubation. In this case report we identified a case of previously healthy man who was intubated for General Anaesthesia for extraction of impacted molar tooth. Soon after extubation he developed severe respiratory distress. Immediate diagnosis of NPPE secondary to post extubation laryngospasm was made. He was promptly treated with 100 percent oxygen via CPAP (continuous positive airway pressure) mask and within an hour he markedly improved and subsequently became asymptomatic. NPPE is an important cause of morbidity and need …

Differentiating Asthma From Its Mimics, Zeeshan Waheed, Muhammad Irfan, Mohammad Salih, Ali Bin Sarwar Zubairi Jan 2011

Differentiating Asthma From Its Mimics, Zeeshan Waheed, Muhammad Irfan, Mohammad Salih, Ali Bin Sarwar Zubairi

Section of Pulmonary & Critical Care

All that wheezes is not asthma this adage accredited to Chevalier Jackson emphasizes the importance of differentiating asthma from its mimics, particularly if the patient is not responding to usual therapy. The above statement also warrants further diagnostic evaluation and management of non-asthma conditions that mimic asthma. We present here a case of a middle aged female who presented with severe bronchospasm, initially labeled as asthma but was resistant to usual anti-asthma therapy. After further workup she was eventually diagnosed to have esophageal achalasia.
