Approaches to the diagnosis of smear-negative and sputum-scarce TB in South Africa
… Africa, an HIV-endemic setting, the burden of smear-negative (SN) and sputum-scarce (SS) TB is a major public health catastrophe. Diagnostic delay or failure is a key bottleneck. We hypothesised that i) assisted sputum smpling using sputum induction (SI), and ii) the use of the newer diagnostic …

Barriers and facilitators to colposcopy attendance following an abnormal pap smear: patient and provider perspectives
… if women with abnormal Papanicolaou (Pap) smears are appropriately investigated. Colposcopy attendance following an abnormal Pap smear is a major problem in South Africa. The aim of this study was to explore barriers and facilitators to colposcopy attendance following an abnormal Pap smear …

A two phase local study, comparing liquid-based cytology to the conventional cervical pap smear
… where only 5% of women receive a repeat PAP smear within a five year period. The lifetime risk for the development of cervical cancer in black South African women is an estimated 1 :26 compared to 1 :83 for white South African women, the majority of whom have been screened. The age …

Creating a virtual slide map from sputum smear images for region-of-interest localisation in automated microscopy
… for the detection of tuberculosis (TB) in sputum smears seeks to address the strain on technicians in busy TB laboratories and to achieve faster diagnosis in countries with a heavy TB burden. As a step in the development of an automated microscope, the project described here was concerned with …

pH Change Following Smear Layer Removal and Final Rinse with 95% Ethyl Alcohol Using Calcium Hydroxide Medicament or BC Sealer
Introduction: An in vitro investigation of pH change at the external root surface after final rinse of 95% ethyl alcohol using Ultracal XS, Calasept Plus, or obturation with BC sealer. Methods: 80 single rooted extracted human teeth were decoronated with a standardized root length of 15mm. All root …

A cost effectiveness analysis of different ways of analyzing sputum for turberculosis diagnosis: direct smear microscopy, natural sedimentation and centrifugation
In Malawi, sputum smear microscopy (Ziehl-Neelsen) is a major diagnostic technique for pulmonary tuberculosis (TB). Though relatively rapid, it tends to be poorly sensitive since it requires a large number of organisms to be present in the specimen before they can be detected. Two approaches that …

Can clinical audit, an intervention to influence medical practice, improve the diagnosis of smear negative tuberculosis in three Latin American countries?
BACKGROUND Clinical audit is an intervention designed to improve the quality of clinical care. Although well established in high income countries, there is little research evidence for its effectiveness in resource poor settings. AIMS AND OBJECTIVES I aimed to evaluate the effectiveness of clinical …

The relative importance of barriers to cervical cancer screening in older women : A review of 140 women and their pap smear providers
… 50 and 69 years (M "'58.21 years) and 23 Pap smear providers completed a Cervical Cancer Screening Questionnaire designed to identify the relative importance of barriers to attendance for cervical screening, as well as providers own barriers and issues. Responsibility for health, familiarity …

Utility of newer and novel technologies for the diagnosis and treatment-monitoring of tuberculosis using different biological fluids
Smear microscopy has a poor sensitivity, cannot identify drug resistance, and when followed up with culture tests it takes several weeks to obtain a result. Furthermore, sputum-scarce and smear negative tuberculosis is difficult to diagnose. The use of biological samples other than sputum such as …
