Imaging phaeochromocytoma
Item type: Journal Article • Journal: Journal of Endocrinology, Metabolism and Diabetes of South Africa • Authors: Janse P van Rensburg --- Division of Radiodiagnosis, Department of Medical Imaging and Clinical Oncology, Faculty of Health Sciences, South AfricaThe phaeochromocytoma (pheochromocytoma) is a hormonally active tumour of neuroendocrine origin. This article reviews the embryology, anatomy, nomenclature and pathology as it relates to the imaging of phaeochromocytomas and paragangliomas. The imaging findings and the role of different imaging modalities... -
A review of the radiological imaging modalities of non-traumatic small bowel obstruction
Item type: Journal Article • Journal: South African Family Practice • Authors: Narisha Maharaj --- Department of Radiology, South Africa Bhugwan Singh --- Department of Surgery, South AfricaSmall bowel obstruction is a common clinical presentation that presents a diagnostic conundrum. Over the last 2 decades, there has been a paradigm shift in the radiological investigation of small bowel obstruction (SBO) and in the indication for and timing... -
Imaging in gynaecological oncology follow-up
Item type: Journal Article • Journal: Southern African Journal of Gynaecological Oncology • Authors: B R Howard --- Department of Obstetrics and Gynaecology, Gynaecology Oncology Unit, R P Soeters --- Department of Obstetrics and Gynaecology, Gynaecology Oncology Unit,The early detection of a gynaecological cancer recurrence is important in order to institute early treatment. Numerous imaging techniques have been used to follow up patients after treatment of gynaecological malignancies. These include plain X-rays, ultrasound, CT scan, MRI scan... -

Three-dimensional visualisation of brooding behaviour in two distantly related brittle stars from South African waters
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: J Landschoff --- Department of Biological Sciences and Marine Research Institute, South Africa CL Griffiths --- Department of Biological Sciences and Marine Research Institute, South AfricaBrooding in ophiuroids (Echinodermata: Ophiuroidea) is a highly-developed reproduction strategy and has evolved independently several times. In South African waters, brooding occurs both in the very small amphiurid Amphipholis squamata, which is hermaphroditic, and in the large ophiodermatid Ophioderma wahlbergii,... -
Sheddable armour: identification of osteoderms in the integument of Geckolepis maculata (Gekkota)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Daniel J. Paluh --- , , USA Aaron H. Griffing --- , , USA Aaron M. Bauer --- , , USAOsteoderms are bony deposits that form within the dermal layer of skin in vertebrates. Within geckos, osteoderms are uncommon, only described in Gekko gecko and the genus Tarentola.

Comparative skull osteology and preliminary systematic revision of the African lizard genus Heliobolus (Squamata: Lacertidae)
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Mirjam Dubke --- , Germany Christy A. Hipsley --- , Germany Johannes Müller --- , GermanyThe anatomy of African lacertid lizards (Lacertidae: Eremiadini) is poorly known, which has hindered a better understanding of their evolutionary relationships. This applies especially to the East African clade, which includes the genera Nucras, Latastia, Philochortus, Pseuderemias and Heliobolus. We... -

Digging adaptations evolved independently in two lineages of Psammophiid snake: evidence from cranial morphology
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Nick Sekits --- Whitman College, United States Walter Tunnell-Wilson --- Whitman College, United States Kate Jackson --- Whitman College, United StatesThe Beaked Snakes (Rhamphiophis) are semi-fossorial snakes with reinforced snouts adapted for digging. The Skaapstekers (Psammophylax) are generalist terrestrial snakes. Both belong to the family, Psammophiidae. The Striped Beaked Snake (Kladirostratus acutus) was originally assigned to the genus Rhamphiophis, because... -
