HIV/AIDS pandemic has caused a resurgence of TB, resulting in increased morbidity and mortality worldwide. HIV and Mycobacterium tuberculosis have a synergistic interaction; each accentuates progression of the other. Clinical presentation of TB in early HIV infection resembles that observed in immunocompetent persons. In late HIV infection, however, TB is(More)
Miliary tuberculosis is a potentially lethal form of tuberculosis resulting from massive lymphohaematogeneous dissemination of Mycobacterium tuberculosis bacilli. The emergence of the HIV/AIDS pandemic and widespread use of immunosuppressive drugs has changed the epidemiology of miliary tuberculosis. Impaired cell-mediated immunity underlies the disease's(More)
Malaria is an important treatable cause of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) in the tropics and in the returning traveller in the non-endemic areas. ARDS is an important complication in severe, complicated falciparum malaria and has been described in P. vivax and P. ovale malaria also. Malarial ALI/ARDS is more common in(More)
Multidrug-resistant tuberculosis (MDR-TB), caused by Mycobacterium tuberculosis that is resistant to both isoniazid and rifampicin with or without resistance to other drugs, is a phenomenon that is threatening to destabilize global tuberculosis (TB) control. MDR-TB is a worldwide problem, being present virtually in all countries that were surveyed.(More)
Chikungunya fever, caused by "Chikungunya virus," is an arbovirus disease transmitted by the bite of infected mosquitoes belonging to the genus Aedes. Chikungunya fever epidemics have been reported from several countries around the world. The disease that was silent for nearly 32 years re-emerged in the October 2005 outbreak in India that is still ongoing.(More)
BACKGROUND Drug-induced hepatotoxicity (DIH) is the most common adverse drug reaction leading to interruption of antituberculosis treatment. Worldwide, different reintroduction regimens have been advocated, but no consensus guidelines are available. Reintroduction of antituberculosis drugs in patients with DIH has never been studied systematically. We aimed(More)
INTRODUCTION AND AIM OF THE STUDY To document abnormalities on spirometry in patients with type1 diabetes mellitus (DM) and to study the determinants of these. MATERIAL AND METHODS Thirty nine patients attending the type 1 DM clinic underwent spirometry. The absolute FEV1 and FVC were compared with the predicted ones and expressed as a percentage of the(More)
The objective of this prospective observational clinical study is to derive and validate a diagnostic model for prediction of obstructive sleep apnea (OSA) in subjects presenting with non-sleep-related complaints in a tertiary care center in north India. We included 102 subjects (group I, range 31-70 years) presenting to the hospital with non-sleep-related(More)
BACKGROUND & OBJECTIVES Antituberculosis (anti-TB) drug induced hepatotoxicity (DIH) is the most common side effect leading to interruption of therapy. Wide variations have been found in the reported incidence of hepatotoxicity during short-course chemotherapy. Several risk factors for hepatotoxicity have been suggested in previous studies. We undertook a(More)
Tobacco consumption ranks high among the leading health risks and tuberculosis (TB) is a major public health issue in countries where the smoking problem has reached epidemic proportions. Given that both smoking and TB are major health concerns and are widely prevalent in several countries, it is surprising that the association between smoking and TB is(More)
