The kinetics of changes in inflammatory indices in induced sputum from eight prednisone dependent asthmatics whose minimum clinical maintenance and exacerbation doses were known were investigated. The study began on the last day of a course of 30 mg prednisone daily for one week. Thereafter, the daily prednisone was reduced in a structured way to below the maintenance dose. This treatment was c...

Although the Gram stain and culture of expectorated sputum are considered standard methods for the diagnosis of presumptive pneumococcal pneumonia, these methods remain relatively insensitive and nonspecific. We developed an enzyme immunoassay (EIA) for the quantitation of pneumococcal C polysaccharide (PnC) in the sputum of patients with presumptive pneumococcal pneumonia. Of 34 patient sputum...

A retrospective study of laboratory reports of sputums examined in the first 3 months of 1977 and of 1978 showed some interesting findings, which were similar in these 2 years. Analysis of the findings demonstrated that information from a proportion of sputum cultures were not helpful to the clinicians. Probable causes of such unhelpful results and some ways to overcome these problems were disc...

Introduction: Diagnosis of tuberculosis under the National Tuberculosis Control Program (NTCP) is based on microscopic examination of sputum. The main objective of this study was to assess the perception of physicians and patients regarding the importance of chest X-ray in diagnosing pulmonary tuberculosis with a view to suggest corrective measures. Materials & Methods: One hundred and eight...

BACKGROUND Improving childhood tuberculosis (TB) evaluation and care is a global priority, but data on performance at community health centers in TB endemic regions are sparse. OBJECTIVE To describe the current practices and quality of TB evaluation for children with cough ≥2 weeks' duration presenting to community health centers in Uganda. METHODS Cross-sectional analysis of children (<15 ...

The simplest, cheapest, and fastest diagnostic method for tuberculosis (TB) is the detection of acid-fast bacilli (AFB) by microscopy. The algorithm advised for the diagnosis of TB recommends examination of three consecutive sputum specimens from TB suspects for the presence of AFB. In the present study, we evaluated the contribution of each specimen to the final detection of TB suspect patient...

One of the limitations in the use of induced sputum to measure indices of airway inflammation is the perceived need to process the sample within 2 h. Therefore, the authors investigated whether the processing of induced sputum could be delayed. Induced sputum samples obtained from asthmatic subjects (n=30) were examined. Each sample was stored at 4 degrees C. A portion was selected and processe...
