Inhibition of neutral endopeptidase (NEP) facilitates neurogenic inflammation

2005

Neutral endopeptidase (NEP) and angiotensin-converting enzyme (ACE) are involved in neuropeptide degradation and may modulate neurogenic inflammation. We therefore explored the effect of specific blockers of NEP and ACE on the intensity of neurogenic inflammation. We investigated eight subjects on three occasions. Two pairs of microdialysis fibers equipped with intraluminal wires were inserted intracutaneously into the volar forearms and electrical stimuli were delivered via the intraluminal electrodes. The microdialysis fibers were perfused either with normal saline, phosphoramidon (NEP inhibitor), or captopril (ACE inhibitor). CGRP release was assessed in the microdialysis eluate via a sp…

Hemisensory disturbances in patients with complex regional pain syndrome.

2018

Sensory disturbances often spread beyond the site of injury in complex regional pain syndrome (CRPS) but whether this applies equally to CRPS I and II, or changes across the course of the disease, is unknown. Establishing this is important, because different symptom profiles in CRPS I and II, or in acute vs chronic CRPS, might infer different pathophysiology and treatment approaches. To explore these questions, sensory disturbances were assessed in the limbs and forehead of 71 patients with CRPS I and 33 patients with CRPS II. Pain had persisted up to 12 months in 32 patients, for 13 to 36 months in 29 patients, and for longer than this in 43 patients. Patients with CRPS I were more likely …

Systemic Treatment in Advanced Phyllodes Tumor of the Breast: A Multi-institutional European Retrospective Case-series Analyses

2022

Abstract Background: We aimed at investigating outcome of systemic treatments in advanced breast PT. Methods: All cases of advanced breast PT treated with systemic treatments from 1999 to 2019, in one of the referral sarcoma centres involved in the study, were retrospectively reviewed. Results: 56 female patients were identified. Median age was 52 (range 25-76) years. Patients re-ceived a median number of 2 systemic treatments (range 1-4). Best responses according to RECIST were: 1 (3.7%) CR, 11 (40.7%) PR, 6 (22.2%) SD, 9 (33.3%) PD with anthracyclines plus ifosfamide (AI); 2 (16.7%) PR, 4 (33.3%) SD, 6 (50.0%) PD with anthracycline alone; 3 (18.8%) PR, 4 (25.0%) SD, 9 (56.3%) PD with high…

Surgical Neuropelveology: Lateral Femoral Cutaneous Nerve Endometriosis. Laparoscopic Resection and Nerve Transplantation

2021

ABSTRACT Study Objective To demonstrate the application of surgical neuroanatomic principles for the diagnosis and treatment of deep infiltrating endometriosis involving the lateral femoral cutaneous nerve. Design Video demonstration of laparoscopic lateral femoral cutaneous endometriosis resection with nerve transplant. Setting Endometriosis infiltrating somatic nerves is a poorly known condition, which can cause severe neuropathic symptoms [1] and is often unrecognized with a subsequent treatment delay [1] . Intimate knowledge of pelvic neuroanatomy and expertise in minimally invasive surgery are essential to manage this challenging surgical scenario 2 , 3 , 4 . Interventions Thirty-six y…

Depletion of Alloreactive Donor T Lymphocytes by CD95-Mediated Activation-Induced Cell Death Retains Antileukemic, Antiviral, and Immunoregulatory T …

2007

In allogeneic hematopoietic stem cell transplantation (AHSCT) graft-versus-host disease (GVHD) and graft-versus-leukemia (GVL) effect are closely but not invariably linked. Thus, harnessing donor lymphocyte mediated GVL immunity and separating it from GVHD is of particular interest. Based on results obtained in murine models we have explored the CD95-mediated activation-induced cell death (AICD) strategy to selectively deplete alloreactivity in human donor T lymphocytes in vitro. Following stimulation of CD3(+) T cells isolated from HLA-A* 0201-positive donors with HLA or minor histocompatibility antigen mismatched hematopoietic or nonhematopoietic cells in the presence of agonistic anti-CD…

Chapter 1 Pain and hyperalgesia: definitions and theories

2006

Publisher Summary This chapter describes pain as an unpleasant sensory and emotional experience associated with actual or potential tissue damage. It reflects the first-person perspective of pain: “pain is an unpleasant sensory and emotional experience.” “Nociception” is a term that may more adequately reflect these aspects of pain sensation. The chapter reviews that the adequate stimulus to activate the receptive organs of the nociceptive system consists of either actual or potential tissue damage. But not all noxious stimuli are detected by the nociceptive system. Therefore, the adequate stimulus for this system in the strict sense is that subset of noxious stimuli that can be encoded by …

Photoactivation of Anticancer Ru Complexes in Deep Tissue: How Deep Can We Go?

2017

Activation of anticancer therapeutics such as ruthenium (Ru) complexes is currently a topic of intense investigation. The success of phototherapy relies on photoactivation of therapeutics after the light passes through skin and tissue. In this paper, the photoactivation of anticancer Ru complexes with 671-nm red light through tissue of different thicknesses was studied. Four photoactivatable Ru complexes with different absorption wavelengths were synthesized. Two of them (Ru3 and Ru4) were responsive to wavelengths in the “therapeutic window” (650–900 nm) and could be activated using 671-nm red light after passing through tissue up to 16-mm-thick. The other two (Ru1 and Ru2) could not be ac…

Central pain processing in patients with shoulder pain : a review of the literature

2017

Background Shoulder pain is a common health problem in which changes in shoulder structure cannot always explain the patient's perceived pain. Central sensitization (CS) might play a role in a subgroup of these patients. Methods The literature was systematically reviewed to address the role of CS in patients with shoulder pain. Electronic databases PubMed and Web of Knowledge were searched for relevant studies. Results Eighteen full-text articles were included, methodological quality was scored, and information was extracted. Studies were clustered on those studying patients with musculoskeletal (MSK) shoulder pain and those studying patients with hemiplegic shoulder pain (HSP). In particul…
