Background: The papanicolaou (pap) smear has been used to screen cervical cancer since 1940. Recently, a number of new technologies have been developed to improve the detection of cervical cancer and its precursors. However, there is substantial controversy about whether the new tests offer meaningful advantages over the conventional pap smear. Ideally, these new tests will increase the early d...
BACKGROUND Many women undergoing cervical screening as part of a national South African screening programme may be positive for HIV. The performance of liquid-based cytology (LBC) on samples from HIV-positive women needs to be determined. OBJECTIVES The performance of the Cellslide® automated LBC system was evaluated as a possible alternative to conventional cytology in a national cervical ca...
OBJECTIVE The aim of this study was to examine cells (split-sample) that were retained on sampling devices used to collect conventional Pap smears (primary smears) in order to evaluate specimen adequacy and cytological diagnosis of scrapings that are routinely discarded. STUDY DESIGN Cervical scrapings from women attending routine cervical cancer screening were obtained using a cervical brush...
Background and purpose: Because of the importance of early diagnosis of cervical cancer and high false negative results of conventional smear method, several studies have been performed to find a more appropriate test in recent years. Fluid-based methods especially thin prep are considered to have the highest potential to reduce the false negative results and to increase the adequacy of speci...
BACKGROUND Collection technique is critical in the performance of the Papanicolaou (Pap) smear as an important screening tool for cervical cancer. While superior devices have been established, less effective devices continue to be used for both conventional and liquid-based Pap smears. Our aim is to determine the performance of collection devices currently used in obtaining conventional Pap sme...
BACKGROUND Desmoplastic melanoma is a variant of malignant melanoma that can range in appearance from sarcomatoid to scar-like. Cytomorphology of desmoplastic melanoma has been previously described on conventional smears; however, to our knowledge, detailed cytomorphology on ThinPrep has so far not been described. Herein, we describe the cytomorphology of two cases of desmoplastic melanoma on f...
We used a slide culture technique to detect tubercle bacilli surviving in sputum smears (n=46) after conventional heat fixation and Ziehl-Neelsen staining. In all heat-fixed sputum smears, tubercle bacilli survived after time 0 (n=22), 24 h (n=7), 48 h (n=7), 72 h (n=4), and seven days (n=6). None of the stained sputum smears showed growth on slide cultures. Viable tubercle bacilli remaining in...
