Do nurses risk underestimating the problems of patients with frontal lobe neoplasms?
Patients with frontal lobe neoplasms seemed, overall, to run the same risk of their problems being underestimated as patients with cerebral neoplasms located at other sites. Neurosurgical nurses tended to overestimate patients' problems, particularly in cases with neoplasms not located in the frontal lobe. This unexpected finding needs to be addressed with further research, and might warrant a different approach to caring for patients with frontal lobe neoplasms, whose problems are overestimated less, so that they might receive less supportive care.
This study shows that tonic pain alters visual cortex excitability, a brain region unrelated to pain processing. These changes probably reflect defensive strategies against pain. Extending the study from healthy volunteers to patients with migraine between attacks would offer the opportunity to investigate visual cortical excitability under conditions when baseline habituation is absent.
