Transabdominal Motor Action Potential Monitoring of Pedicle Screw Placement During Minimally Invasive Spinal Procedures: A Case Study.

Precise pedicle screw placement is a critical skill during minimally invasive spinal surgeries but can pose various challenges. Techniques such as electromyography (EMG) have been traditionally utilized for this purpose but have several shortcomings. Transabdominal motor action potential (TaMAP) has been examined as a possible effective neuromonitoring alternative and is hypothesized to provide important data on symptomatic malpositioned pedicle screws.

Mirtazapine for pruritus.

Pruritus is a relatively rare but distressing symptom associated with cholestasis, renal failure, and malignancies. Medical management recently has included the use of ondansetron and paroxetine. We report four patients whose pruritus responded to mirtazapine.
