Tuberculosis and anaesthesia.

Anaesthesiologists and other healthcare workers have been at risk for nosocomial infection with tuberculosis for many years, however the advent of effective infection control techniques and the development of antibiotics for Mycobacterium tuberculosis have decreased the risk of nosocomial infection. The risk of transmission of tuberculosis from patients to healthcare workers is a neglected problem in many developing and underdeveloped countries as they lack the resources to prevent nosocomial transmission of tuberculosis. Patients with active tuberculosis can present with problems related to tuberculosis or unrelated problems like trauma to anaesthetist for various surgeries.

Chronic necrotising pulmonary aspergillosis: a rare complication in a case of silicosis.

Chronic necrotising pulmonary aspergillosis (CNPA) is a rare complication of silicosis whose diagnosis requires a high index of suspicion as it mimics tuberculosis. We report a case of a 52-year-old male with a long history of silica dust exposure and progressively increasing dyspnoea for the past eight years, productive cough, fever, weight loss for past three months and hemoptysis for preceding three weeks. Based on the clinical, radiological and microbiological evidence, he was diagnosed to be a case of CNPA with aspergilloma complicating silicosis.

Scimitar syndrome: imaging by magnetic resonance angiography and Doppler echocardiography.

We report magnetic resonance angiographic demonstration of both an anomalous pulmonary venous drainage and an anomalous systemic arterial supply in a patient with scimitar syndrome. Contrast-enhanced magnetic resonance angiography provides an excellent non-invasive diagnostic tool for demonstrating this complex congenital lesion in detail. A two-dimensional and colour Doppler echocardiography was also performed to show the anomalous venous drainage and to analyse the anomalous flow velocity pattern.
