Traumatic Rupture of the Aorta

nervous system may have a bearing on the production of " functional hyperinsulinism."Cori (1931) in an extensive review concluded that vagal impulses play a part in the finer regulation of the insulin production, and Cannon et al. (1924) have shown that nervous control of the adrenal medulla via the splanchnic nerves ensures a rapid adrenaline response.It can well be appreciated how the continuance of abnormal stress in a susceptible individual may give rise to abnormality or instability in the control of these opposing impulses by the hypothalamic region.The terminal stages of the glucose- tolerance test is illustrative of this.Summary A case of " reactive hyperinsulinism," manifest by an excessive post-prandial fall of the blood-sugar level, is described.Points in the differential diagnosis from hyperinsulinism' due to tumour of the pancreatic islets are discussed.My thanks are due to Dr. H.
