Refractory angina pectoris (RAP) is a clinical syndrome characterized by persistent chest pain caused by myocardial ischemia that is unresponsive to optimal pharmacological therapy and revascularization procedures. Spinal cord stimulation (SCS) has emerged as a promising therapeutic option for managing RAP, offering significant symptom relief and improved quality of life. A systematic literature review was conducted to evaluate the clinical effectiveness, mechanisms of action, and safety profile of SCS in treating RAP.

Methods: A patient with C3-C6 myelomalacia and spastic tetraparesis previously treated with decompressive laminectomy underwent implantation of 10 kHz SCS for pain management through a trial procedure followed by permanent implantation. Due to the presence of epidural fibrotic scar tissue in the area of the previous C3-C6 laminectomy, the leads could not be implanted at the cervical level; therefore, the leads were positioned at the thoracic level.
The authors report their experience with twenty-one consecutive patients who presented with symptoms and imaging characteristics of a herniated lumbar disc; of whom, at the time of surgery had a vascular loop instead. The procedure was performed on 14 women and seven men with a mean age of 39 years. Clinical complaints included lumbar aching with one limb overt radiculopathy in all patients; with additional sphincter dysfunction in two cases.

Article Synopsis
- A study on adult patients with degenerative disc disease and chronic low back pain compared two surgical techniques: stand-alone pedicle screw fixation (SAPF) and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF).
- The research included 62 patients who had undergone surgery, assessing outcomes like pain levels and patient satisfaction at a 24-month follow-up.
- Findings showed no significant differences in pain scores, patient satisfaction, or lumbar lordosis between the two surgical techniques, although both groups reported improved walking distance post-surgery.

Background: Febrile neutropenia is a life-threatening condition commonly observed in patients with hematologic malignancies. The aim of this article is to provide updated knowledge about bloodstream infections in febrile neutropenia episodes within the Andean region of Latin America.
Method: This retrospective study was based in 6 hospitals in Chile, Ecuador, and Peru and included adult patients with acute leukemia or lymphoma and febrile neutropenia between January 2019 and December 2020.
