The progression of sensory blockade in the hand following a forearm Bier block with ropivacaine is currently unknown. The hands of 10 healthy adult human subjects were anesthetized with ropivacaine, and their sensitivities to cold and touch were tested until the completion of anesthesia. On average, insensitivity to cold occurred uniformly throughout the hand within 9 mins; however, touch sensation was not complete until approximately 20 mins after injection. The spread of anesthesia occurred in a semisystematic way, spreading proximally and distally from the site of injection (mid-dorsum of the hand), and, at a slower rate, from the dorsum of the hand to the palm.

Safety of pre-operative venogram for hemodialysis access planning in pre-end-stage kidney disease patients.

Background: Although conventional pre-operative venography can accurately delineate venous anatomy as an alternative to ultrasound for hemodialysis access planning, it may carry a risk of contrast-induced acute kidney injury (AKI) and progression of renal failure in chronic kidney disease (CKD) patients not yet on dialysis. Therefore, the objective of this study was to evaluate the safety and efficacy of pre-operative venograms in pre-end-stage kidney disease (ESKD) patients.
Methods: We performed a retrospective cohort study (2018-2022) of consecutive pre-ESKD patients who underwent staged bilateral venograms for preoperative vein mapping prior to hemodialysis access creation at a tertiary care medical center.

Vascular access for coronary, peripheral, and structural interventions has changed significantly over the past two decades. The evolving demand for both large-bore access for valvular interventions and mechanical support devices, and for safer access for coronary interventions, in patients with comorbidities have driven progress in these areas. This review will provide an overview of the techniques of arterial access in the femoral, forearm (radial and ulnar), and alternative (transcarotid, transaxillary, and transcaval) locations based on the latest evidence and experience.

Purpose: Effective rehabilitation after orthopaedic surgery is critical. The early post-operative phase is increasingly managed in outpatient settings, necessitating objective measures such as step counts to monitor rehabilitation progress. However, it remains unclear if commercially available wearables or accelerometers using simple algorithms can accurately count steps in early post-operative conditions.

Article Synopsis
- A 50-year-old man presented with a large mass in his left thigh causing significant pain and impaired functionality, with imaging showing widespread tumors in several body parts, but the primary cancer source was unknown.
- Despite rapid tumor progression, he began treatment with nivolumab, an immunotherapy drug, and further genomic profiling led to a re-diagnosis of SMARCA4-deficient epithelioid sarcoma.
- After 5 weeks of treatment, the patient showed significant improvement despite facing some immune-related side effects; by the 12th dose, he had a positive response to the therapy with no new complications.

Shoulder septic arthritis is a severe infection of the shoulder joint, commonly caused by bacteria such as . It leads to inflammation, severe pain, swelling, and reduced mobility in the affected shoulder. The condition is typically diagnosed through clinical evaluation, blood tests, imaging studies, and joint aspiration.
