RESUMEN
Introduction The tuberculosis (TB) diagnosis involves various methods, such as microscopic examination, culture-based methods, molecular techniques, chest X-rays, serological tests, and interferon-gamma release assays. These methods help identify and confirm TB and its resistance to rifampicin, balancing speed and accuracy for prompt treatment initiation and effective disease management. Aims and objectives To assess the diagnostic accuracy of GeneXpert, Ziehl-Neelsen staining, and fluorescence staining compared to culture media in TB-suspected patients. Materials and methods We analysed 416 patient samples for TB over one year using GeneXpert, Ziehl-Neelsen staining, fluorescence staining, and Löwenstein-Jensen (LJ) medium. Only samples with a suspicion of TB were included in the study. The samples received without clinical history and requests for all four tests were excluded. Results A total of 416 patient samples were categorised into pulmonary and extrapulmonary samples. GeneXpert detected 62 positive cases for TB, out of which 53 were rifampicin-sensitive, seven were rifampicin-indeterminate, and two were rifampicin-resistant. The indeterminate samples were further evaluated using the line probe assay (LPA), of which six were rifampicin-sensitive, and one was rifampicin-resistant. Fluorescent staining detected 44 cases, Ziehl-Neelsen staining detected 40 cases, and LJ culture medium detected 65 cases. Conclusion GeneXpert is superior to staining methods for detecting TB. GeneXpert, combined with microscopy and culture, can enhance TB and multi-drug resistant tuberculosis (MDR-TB) detection and aid in early treatment initiation.
RESUMEN
INTRODUCTION: Urinary incontinence (UI) is increasingly recognized as a significant health problem, which remains a hygienic as well as social problem. Women have higher risk of developing incontinence in their lifetime compared with men. Urinary tract infection can increase the incidence of incontinence. Present study was undertaken to assess the association of UTI in married women who presented with UI. AIM: The present study was aimed to identify the patients (married women) with complaints of UI and determining its association with UTI; and to identify the causative organism for the UTI along with its antimicrobial susceptibility pattern. MATERIALS AND METHODS: This is a cross-sectional, non-randomized study of 107 married women with UI, who attended outpatient department in our hospital. Mid-stream urine (MSU) samples were collected from these patients with positive history of incontinence. Screening of urine for significant bacteriuria and culture to identify the etiological agents were performed followed by evaluation of their antimicrobial susceptibility profiles using Kirby Bauer disc diffusion method. RESULTS: Overall 25.2% of patients with incontinence had a positive urine culture. History of UTI was elicited in around 38.3% of patients, among which 15% had positive urine culture and 10.3% of the patients who did not have a history had positive culture. Escherichia coli was the commonest causative organism (66.6) causing UTI, followed by Enterococcus spp. (22.3%), Klebsiella pneumoniae (7.4%) and Proteus mirabilis (3.7%). The antimicrobial susceptibility pattern for Escherichia coli showed high sensitivity to Nitrofurantoin (94.4%) and high resistance to Ampicillin (94.4%). CONCLUSION: Our study revealed one in every four incontinent patients had UTI and almost half of them suffered from previous episodes of UTI. Thus appropriate correction of the existing UTI can help in the treatment of UI.
