Blood circulation was measured by laser doppler flowmetry in fasciocutaneous flaps of 24 patients who underwent reconstructive surgery for mammary carcinoma. 19 of the 24 patients had clinical signs of deficient circulation in the flaps. 14 patients were treated with electrical nerve stimulation (ENS) and 10 with placebo-ENS. Varying degrees of necrosis developed in 8 of the 10 patients who received placebo stimulation but in none of those treated with ENS. In the 5 patients with good capillary refilling and no signs of stasis or oedema before treatment, only minor increases in blood flow occurred after ENS.

Home and outpatient electrostimulation in the treatment of urinary incontinence in women: a systematic review.
BMC Womens Health
January 2025
Postgraduate Program in Medicine and Human Health, Bahiana School of Medicine and Public Health, Rua Silveira Martins, nº 3386, Cabula, Salvador, BA, 41150-000, Brazil.
Introduction And Hypothesis: Urinary incontinence (UI) is defined as any involuntary loss of urine and can be associated with urgency and/or physical exertion. Electrical stimulation (ES) has recently been identified as a proven therapeutic alternative for UI, with few side effects and low cost. This systematic review, registered on the Prospective Register of Systematic Reviews (RD42024528812), investigated whether home-based ES would be as viable as outpatient ES in the treatment of women with UI.

Direct current (DC) electrical block of peripheral nerve conduction shows promise for clinical applications to treat spasticity, pain, and cardiac arrhythmias. Most previous work has used invasive nerve cuffs. Here we investigate the potential of non-invasive transcutaneous direct current motor block (tDCB).

Department of Regional Health Research, University of Southern Denmark, Odense, Denmark.
Background: The objective was to investigate if cryoneurolysis were superior to sham in reducing pain intensity in patients with chronic knee osteoarthritis. We hypothesized that cryoneurolysis was an effective and safe therapy to reduce chronic pain in patients with knee osteoarthritis.
Methods: The study was a randomized, double-blind, sham-controlled.
Abolition of Aorticorenal Ganglia Pacing Responses Improves Denervation Efficacy.
Hypertension
January 2025
Cardiology Department (P.B., X.L., V.T.T., M.A.B., A.V., E.Y., D.M.N., U.P., J.L., S.P.T., P.C.Q.), Westmead Hospital, Sydney, Australia.
Background: Transcatheter renal denervation (RDN) remains inconsistent despite developments in ablation technologies, due to the lack of an intraprocedural physiological end point.
Objective: To identify whether aorticorenal ganglion (ARG) guided RDN using microwave (MW) catheter leads to more consistent denervation outcomes compared with empirical MW ablation.
Methods: Pigs underwent sham procedure (n=8) or bilateral RDN using an in-house built open-irrigated MW catheter.
Technical aspects of neuraxial analgesia during labor and maternity care: an updated overview.

Labor analgesia is increasingly widespread throughout the world with a rate ranging from 10 to 60%. The benefits regarding clinical and non-clinical maternal-fetal outcomes are currently discussed in international scientific literature. Even stage of labor needs a different and appropriate approach to control the pain; however, different techniques are reported in literature.
