Histopathology reporting of temporal artery biopsy specimens for giant cell arteritis: results of a modified Delphi study.

Unlabelled: The temporal artery biopsy (TAB) is regarded as the gold-standard test in the diagnosis of giant cell arteritis (GCA). There is a lack of agreement among experienced pathologists regarding the diagnostic features and classification of inflammation observed in TAB sections in the diagnosis of GCA.

Aims: The aim of this research study was to establish consensus on the key parameters which should be included in a standardised reporting proforma for TAB specimens.

The ventrolateral medulla and medullary raphe in sudden unexpected death in epilepsy.

Sudden unexpected death in epilepsy (SUDEP) is a leading cause of premature death in patients with epilepsy. One hypothesis proposes that sudden death is mediated by post-ictal central respiratory depression, which could relate to underlying pathology in key respiratory nuclei and/or their neuromodulators. Our aim was to investigate neuronal populations in the ventrolateral medulla (which includes the putative human pre-Bötzinger complex) and the medullary raphe.
