Article Abstract
Background: Systemic amyloidosis can cause severe refractory pain, often inadequately managed with conventional analgesics. Intrathecal drug delivery systems (IDDS) have been used for chronic pain control but are rarely reported in amyloidosis cases.
Case Report: We present a female patient in her late 50s with systemic light-chain amyloidosis and type III intestinal failure, experiencing significant weight loss and debilitating abdominal pain during enteral and parenteral feeding. After unsuccessful trials of oral analgesics, antineuropathic medications, and interventional procedures, an IDDS was implanted to deliver a combination of bupivacaine and morphine. The therapy allowed her to resume enteral and parenteral nutrition, reduce opioid consumption, gain weight, improve functionality, and decrease hospital admissions despite disease progression.
Conclusions: This case highlights the efficacy of intrathecal analgesia in managing severe refractory pain from amyloidosis. Early consideration of IDDS may improve quality of life in similar patients by providing effective long-term pain control.

Hypervirulent is a recently identified pathotype characterized by high virulence and rapid dissemination. It is associated with invasive infections at multiple anatomical sites, including liver abscesses, necrotizing fasciitis, meningitis, myositis, and endophthalmitis. It has emerged as a significant threat to public health due to its aggressive clinical course and high mortality rate.

Background: Arnold-Chiari Malformation Type I (ACM-I) is a congenital disorder that can lead to severe neurological symptoms. While decompression surgery is the standard treatment, postoperative complications such as cerebrospinal fluid (CSF) leakage and infections can result in critical outcomes. Here, we report a case of septic shock following decompression surgery in a patient with ACM-I, emphasizing the challenges in postoperative critical care management.

Chemotherapy-induced peripheral neuropathy accompanied by neuropathic pain (CIPN) is a major neurotoxicity of cisplatin, a platinum-based drug widely used for lung, ovarian, and testicular cancer treatment. Chemotherapy-induced peripheral neuropathy accompanied by neuropathic pain causes drug discontinuation and severely affects life quality with no FDA-approved interventions. We previously reported that platinum-based drugs increase levels of sphingosine 1-phosphate (S1P) in the spinal cord and drive CIPN through activating the S1P receptor subtype 1 (S1PR1).

Objectives: Eosinophilia is a hallmark of a variety of disease processes, but its association with chronic pain has not been well-established. We evaluated the incidence and clinical relevance of eosinophilia in patients who underwent spinal cord stimulation (SCS) or intrathecal drug pump (ITP) implantation for high-impact chronic pain.
Materials And Methods: We retrospectively reviewed 212 patients who underwent SCS or ITP implantation between 2017 and 2024 at the University of Arizona, Tucson.
