TL;DR: A consensus statement was produced to guide decision-making on GH replacement in children and adult survivors of cancer, in those treated for intracranial and pituitary tumours and in patients with increased cancer risk.
Journal ArticleDOI
Neurofibromatosis Type 1 and pancreatic islet cell tumours: an association which should be recognized.
TL;DR: A 75-year-old female with known NF-1 was being investigated for episodes of recurrent collapse and results confirmed the presence of endogenous hyperinsulinism according to recent guidelines.
Journal ArticleDOI
A case of post-traumatic isolated ACTH deficiency with spontaneous recovery 9 months after the event.
TL;DR: This is the first reported case of reversible isolated adrenocorticotrophic hormone (ACTH) deficiency following head trauma, and a case of a man who suffered a transient period of secondary hypoadrenalism after a serious TBI.
Journal ArticleDOI
Expression of guanylyl cyclase-B (GC-B/NPR2) receptors in normal human fetal pituitaries and human pituitary adenomas implicates a role for C-type natriuretic peptide.
Iain R. Thompson,Annisa N. Chand,Peter J. King,Olaf Ansorge,Niki Karavitaki,Ceri Alexander Jones,Dolkun Rahmutula,David G. Gardner,Vladimir Zivkovic,Caroline P.D. Wheeler-Jones,Imelda M. McGonnell,Márta Korbonits,Richard A. Anderson,John Wass,Alan S. McNeilly,Robert C. Fowkes +15 more
TL;DR: These data are the first to show NPR2 expression in normal human fetal and adult pituitaries and adenomatous pituitary tissue and suggest a role for these receptors in both pituitsary development and oncogenesis, introducing a new target to manipulate these processes in pituitARY adenomas.
