  • A reporting association of risperidone with pituitary tumors has been observed. (biomedcentral.com)
  • found spontaneous reporting of pituitary tumors to be disproportionately higher among patients treated with risperidone compared with other antipsychotics. (biomedcentral.com)
  • Based on adjusted reporting ratios (that is, reports of specific adverse events as a proportion of all reports of adverse events for a given medication), reports of pituitary tumors were 8-fold higher in risperidone-treated patients than in olanzapine-treated patients, 31-fold higher than in quetiapine-treated patients, 6-fold higher than in ziprasidone-treated patients, and 3-fold higher than in haloperidol-treated patients.

  • Whereas a potential link between risperidone and pituitary tumor cannot be discounted, there may be other explanations for the considerably higher number of tumors reported with risperidone relative to other antipsychotics. (biomedcentral.com)
  • Pituitary tumors represent from 10% to 25% of all intracranial neoplasms. (healthlinkbc.ca)
  • 5 ] Carcinomas account for 0.1% to 0.2% of all pituitary tumors. (healthlinkbc.ca)
  • His laboratory contributed to the discovery of new genes and pathways involved in the physiological adaptation to homeostasis in response to stress, hypoxia (lack of cellular oxygen), physiopathological processes (pituitary tumors),, and to the discovery of new targets for pharmacological treatments.

  • Folliculo-stellate (FS) cells are non-endocrine cells that play a crucial role in paracrine communication within the pituitary and produce factors controlling prolactin and gonadotrophin release. (ox.ac.uk)
  • NBS) and were prepared for quantitative electron microscopy to assess the effects of season on FS and lactotroph cell density, morphology and distribution, as well as on junctional contacts between cells. (ox.ac.uk)
