Stereotactic Radiosurgery for Spinal Haemangioblastoma: A Retrospective Single-Centre Experience from the United Kingdom.

Introduction: Haemangioblastoma is a benign, vascular tumour of the central nervous system. Stereotactic radiosurgery (SRS) is increasingly being used as a treatment for spinal lesions to avoid complex surgery, especially in patients with multi-focal tumours associated with von Hippel-Lindau syndrome (VHL). Here, we present the outcomes of patients treated in our centre using a CyberKnife VSI (Accuray, Inc.

Genetic substructure and complex demographic history of South African Bantu speakers.

South Eastern Bantu-speaking (SEB) groups constitute more than 80% of the population in South Africa. Despite clear linguistic and geographic diversity, the genetic differences between these groups have not been systematically investigated. Based on genome-wide data of over 5000 individuals, representing eight major SEB groups, we provide strong evidence for fine-scale population structure that broadly aligns with geographic distribution and is also congruent with linguistic phylogeny (separation of Nguni, Sotho-Tswana and Tsonga speakers).

Hearing Difficulties as a Result of Traumatic Brain Injury.

Background: Traumatic brain injury (TBI) has been shown to result in hearing difficulties (i.e., deficits in the processing of auditory information) without impacting pure-tone threshold detection.
