Mepivacaine Versus Bupivacaine Spinal Anesthesia for Primary Total Joint Arthroplasty: A Systematic Review and Meta-Analysis.

Background: Mepivacaine is an intermediate acting amide local anesthetic that can be used for neuraxial anesthesia in total joint arthroplasty (TJA) with a shorter duration of action (1.5-2 hours) compared to the more commonly used local anesthetic bupivacaine. The purpose of this study was to perform a systematic review and meta-analysis comparing bupivacaine and mepivacaine spinal anesthesia during elective TJA and the surgical outcomes of the time to full neurologic motor return, pain, mobility, length of stay (LOS), and complications including transient neurologic symptoms and urinary function.

Osteomalacia and Insufficiency Fractures Secondary to Intravenous Iron Therapy: A Case Report.

Introduction: Intravenous (IV) iron therapy is associated with hypophosphatemia, and long-term administration may lead to osteomalacia and insufficiency fracture. Awareness of this complication could severely reduce patient morbidity. Our patient continued her iron therapy for 17 months after her initial complaint.
