    Correlative imaging and histopathology of a complicated sinonasal teratocarcinosarcoma
    (SA Journal of Radiology, 2023) van Zyl, Tineke; Leon, Janse van Rensburg; Opperman, Johan F; Naidoo, Komeela; Merven, Marc
    Sinonasal teratocarcinosarcoma (SNTCS) is a highly malignant and rare tumour characterised by a complex admixture of teratomatous and carcinosarcomatous components. In the head and neck area, it almost exclusively occurs in the sinonasal cavities; however, rare instances of nasopharyngeal and oral cavity involvement have been reported, with fewer than 100 cases reported in the literature. Contribution: The contributed case involves the correlative CT, MRI and histopathology of a sinonasal teratocarcinosarcoma with intracranial involvement

    Dental practitioners’ knowledge and attitude towards ultrasonography at the UWC faculty of dentistry
    (Universty of the Western Cape, 2023) Simpson, Jessica Amy; van Zyl, Tineke
    Ultrasonography (USG) - a method in which images are created using sound waves - has gained popularity in the medical field due to its cost-effectiveness, accessibility, portability, non-invasiveness, lack of ionizing radiation, and ability to produce real-time images. Yet, despite the high rate of disease and trauma in the country, as well as the shocking waiting times of other imaging modalities like MRI, South Africa is still lagging when it comes to incorporating USG in dentistry. Could the reason for this be due to dental practitioners not being aware of the multiple therapeutic and diagnostic abilities of USG and, therefore not willing to make use of an alternate imaging modality?. The Knowledge-Attitude-Behaviour (KAB) model was developed for health promotion and is based on the idea that knowledge will directly affect a person’s attitude, which in turn indirectly affects their behaviour. Therefore, in this case, if dental practitioners were educated about the uses of USG, their attitude towards using this imaging modality when treating patients could change, eventually leading to increased uptake of USG in clinical practice.
