We sought to estimate the total proportion of patients with pediatric tuberculosis, characterize tuberculosis by its anatomical location and sputum smear
status, and to determine any association of the sociodemographic and clinical determinants with tuberculosis infection among pediatric patients in Kelantan.
In conclusion, the levels of rifampicin were below the MIC in most of the samples in both phases of treatment, and there was no significant association between frequency of samples with drug levels below 0.5 [micro]g/mL with conversion of the sputum smears
. These data suggest that pre-doses samples offer limited information on the exposure of M.
Univariate analysis identified older age, higher sputum smear
grading and previous FLD outcomes as factors associated with poor treatment outcome.
The present study was conducted with an objective of comparing the efficacy of various counter stains in Auramine O staining method enabling better detection of acid fast bacilli in sputum smears
According to Alladi Mohan and SK Sharma, sputum smear
negativity in TB cases are due to inadequate sputum sample at the time of examination.
This study was done to assess the nutritional status in sputum smear
positive and sputum smear-negative cases of PTB.
Identifying pulmonary tuberculosis in patients with negative sputum smear
 used two-class pixel classifiers such as Bayes classifier, linear regression classifier, logistic linear classifier and quadratic discriminant classifier to segment the sputum smear
The proportion of AFB sputum smear
positive results was reduced by 2.1% in the last study period, March 2014-Feb.
Table 3 presents the grading of AFB in sputum smear
specimen as evaluated by fluorescent microscopy.
These include high intensity initial sputum smear
AFB grade, cavitary lesion, uncontrolled hyperglycaemia/diabetes mellitus, old age, certain ethnic population (e.g., Hispanic), multidrug-resistant tuberculosis, initial treatment with less than four antitubercular drugs, and non-rifampicin-based treatment regimens [8-14].
Before availability of the Xpert MTB/RIF test, the diagnosis of pulmonary TB in resource-limited settings was based primarily on detection of acid-fast bacilli by sputum smear
