Objective: To compare the effects of general anesthesia combined with epidural preemptive analgesia with general anesthesia on stress reaction in the retroperitoneal laparoscopic surgery.
Methods: Forty patients with adrenal tumors undergoing retroperitoneal laparoscopic surgeries were randomly assigned into general anesthesia combined with epidural preemptive analgesia group (GE) and general anesthesia group (G). Each group had 20 cases.
Purpose: The effect of recombinant human erythropoietin (rhEPO) on neuropathic pain remains unclear. This study aimed to determine the effects of preemptive administration of rhEPO on the behavioural changes and neuroinflammatory responses in a rat model of neuropathic pain.
Methods: Fifty rats were randomly allocated into five groups, sham-operation treated with saline and L5 spinal nerve transection treated with different doses of rhEPO (0 [saline], 1000, 3000, or 5000 U x kg(-1), respectively).

Conclusion: Abnormal caloric and vestibular evoked myogenic potential (VEMP) responses are frequently encountered with a large cerebellopontine angle (CPA) schwannoma, while normal caloric responses and abnormal VEMPs are noted with a large CPA meningioma. This difference may possibly exist because schwannoma causes vestibular deficits via parenchymal involvement, while vestibular deficits in the meningioma are mostly due to compression neuropathy.
Objectives: This study aimed to compare the tumor characteristics in relation to vestibular function, i.
