Nineteen cases of ulnar nerve abscess were subjected to evacuation and later on to extraneural decompression with medical longitudinal epineurotomy. Excellent sensory recovery was seen and was earlier than motor recovery. Sensory recovery was seen more in younger than in elder age group. Evacuation of abscess and "traneural and intraneural decompression reduces the pressure effects on nerve and recovery is seen which can be explained on the basis of increased vascularity postoperatively.

Lateral olivocochlear neurons modulate cochlear responses to noise exposure.

The sense of hearing originates in the cochlea, which detects sounds across dynamic sensory environments. Like other peripheral organs, the cochlea is subjected to environmental insults, including loud, damage-inducing sounds. In response to internal and external stimuli, the central nervous system directly modulates cochlear function through olivocochlear neurons (OCNs), which are located in the brainstem and innervate the cochlear sensory epithelium.

Spinal cord injury (SCI) leads to acute tissue damage that disrupts the microenvironmental homeostasis of the spinal cord, inhibiting cell survival and function, and thereby undermining treatment efficacy. Traditional stem cell therapies have limited success in SCI, due to the difficulties in maintaining cell survival and inducing sustained differentiation into neural lineages. A new solution may arise from controlling the fate of stem cells by creating an appropriate mechanical microenvironment.

Objective: To evaluate the impact of adding epidural dexmedetomidine to low-concentration patient-controlled epidural analgesia (PCEA) on pain control and side effects in total knee arthroplasty (TKA).
Methods: In this double-blind study, American Society of Anesthesiologists I to II patients undergoing TKA were assigned to receive 0.125% bupivacaine + fentanyl 4 µg/mL (group R) or 0.

An origami-based tactile sensory ring utilizing multilayered conductive paper substrates presents an innovative approach to wearable health applications. By harnessing paper's flexibility and employing origami folding, the sensors integrate structural stability and self-packaging without added encapsulation layers. Knot-shaped designs create loop-based systems that secure conductive paper strips and protect sensing layers.

Background Due to its affordability and ease of application, the subarachnoid block is the most frequently used method for lower abdominal procedures. Levobupivacaine has an onset of sensory and motor blockade comparable to that of bupivacaine and prolongs the duration of analgesia while facilitating quick recovery from motor block. Fentanyl and dexmedetomidine, when used as additives to intrathecal local anesthetic, can extend the duration of sensory and motor blockade and enhance postoperative analgesia.
