ABSTRACT
Dystrophic epidermolysis bullosa (DEB) is a rare genetic skin disease characterized by blisters and ulcers on the skin and mucosa after minor friction. The risk of invasive squamous cell carcinoma on the unhealed ulcers increases with age. Tracheal intubation during general anesthesia may induce tracheal stricture due to blister formation and/or scarring in DEB patients and cause severe airway obstruction. There is no consensus for handling DEB patients' fragile mucosa and skin during general anesthesia. We report an adult DEB patient who received two operations under different general anesthesia methods. The experience from this particular patient and her response to anesthesia may provide a satisfactory guide to avoid complications and improve the outcome for DEB patients receiving general anesthesia.

High-frequency spinal cord stimulation (HFSCS) at 10 kHz provides paresthesia-free treatment for chronic pain. However, the underlying mechanisms of its action have not been fully elucidated. The aim of the present study was to investigate the effect of HFSCS treatment on spinal glutamate release and uptake in spared nerve injury (SNI) rats. HFSCS was applied to the T10/T11 spinal cord 3 days after SNI. The concentration of spinal glutamate, glutamate transporter activity and miniature excitatory postsynaptic currents (mEPSCs) from neurons in lamina II were evaluated. HFSCS treatment alleviated SNI pain induced by mechanical and cold allodynia. HFSCS treatment also partially restored altered spinal glutamate uptake activity, the levels of spinal glutamate, and the frequency of mEPSCs following SNI. In conclusion, HFSCS treatment attenuated SNI-induced neuropathic pain and partially restored the altered glutamate uptake after SNI.
