BACKGROUND: Neuronal remodeling in human heart disease is not well understood. METHODS: Stellate ganglia from patients with cardiomyopathy (CMY) and refractory ventricular arrhythmias undergoing cardiac sympathetic denervation (n = 8), and from organ donors with normal hearts (n = 8) collected at the time of organ procurement were compared. Clinical data on all subjects were reviewed. Electron microscopy (EM), histologic, and immunohistochemical assessments of neurotransmitter profiles, glial activation and distribution, and lipofuscin deposition, a marker of oxidative stress, were quantified...

PURPOSE: Palmar hyperhidrosis (PH) is excessive sweating of the palms resulting from sympathetic overactivity, and patients who undergo endoscopic thoracic sympathectomy (ETS) show reduced cardiac demand after 1 year and improved cerebral perfusion within 2-4 weeks. However, the long-term risks of major adverse cardiovascular events (MACE) following ETS remain unclear. METHODS: We searched the Longitudinal National Health Insurance Database in Taiwan and identified PH patients (International Classification of Disease, Ninth Revision, Clinical Modification diagnostic code 708...

OBJECTIVE: The association of antiphospholipid antibody syndrome (APS) and hypercoagulability is well known. Arterial compromise leading to ischemia of organs and/or limbs in patients with APS is uncommon, frequently unrecognized, and rarely described. We evaluated our institutional experience. METHODS: Retrospective review was conducted. From August 2007 to September 2016, 807 patients with diagnosis of APS were managed in our Institution. Patients with primary and secondary APS who required interventions were examined...

BACKGROUND: Catheter ablation is now a mainstay of therapy for ventricular arrhythmias (VA). However, there are scenarios where either physiologic or anatomical factors make ablation less likely to be successful. OBJECTIVES: To demonstrate that cardiac sympathetic denervation (CSD) may be an alternate therapy for patients with difficult to ablate VA. METHODS: We identified all patients referred for CSD at a single center for indications other than LQTS and CPVT who had failed catheter ablation...

Interleukin-17A (IL-17A) is considered an important pro-inflammatory cytokine but its importance in joint diseases such as rheumatoid arthritis (RA) is unclear. It has also been reported that IL-17A may induce pain but it is unclear whether pro-inflammatory and pro-nociceptive effects are linked. Here we studied in wild type (WT) and IL-17A knockout (IL-17AKO) mice inflammation and hyperalgesia in antigen-induced arthritis (AIA). We found that the severity and time course of AIA were indistinguishable in WT and IL-17AKO mice...

BACKGROUND & OBJECTIVES: Hyperhidrosis is a pathologic condition of excessive sweating in amounts greater than physiologic needs. Endoscopic thoracic sympathectomy (ETS) is a globally accepted treatment modality for primary palmar and axillary hyperhidrosis. ETS also has distinctive effects on the heart, circulatory and respiratory systems. In this study early effects of ETS on electrocardiographic (ECG) parameters of hyperhidrosis patients were evaluated. METHODS: Twelve-lead ECGs were performed on 72 patients who were free from cardiovascular, metabolic, neurological and pulmonary diseases and underwent planned ETS because of hyperhidrosis, before and after the procedure within the first 24 h...

We evaluated the endothelial function of patients with Buerger disease using peripheral arterial tonometry test, and examined the factors that are significantly correlated with the endothelial dysfunction in these patients. We performed the peripheral arterial tonometry test in 22 patients with Buerger disease. We recorded the patients' characteristics, including ankle brachial pressure index and reactive hyperemia index, which reflect the endothelial dysfunction. We divided the patients with Buerger disease into the conservative treatment and lumbar sympathectomy group...

Local sympathetic denervation by surgical sympathectomy is used in the treatment of lower limb ulcers and ischemia, but the restoration of cutaneous sympathetic nerve functions is less clear. This study aims to explore the recovery of cutaneous sympathetic functions after bilateral L2-4 sympathectomy. The skin temperature of the left feet, using a point monitoring thermometer, increased intraoperatively after sympathectomy. The cytoplasm of sympathetic neurons contained tyrosine hydroxylase and dopamine β-hydroxylase, visualized by immunofluorescence, indicated the accuracy of sympathectomy...

INTRODUCTION: Treatment refractory ventricular arrhythmias (VAs) are often driven and exacerbated by heightened sympathetic tone. We aim to conduct a systematic review and meta-analysis of published studies of a temporary percutaneous stellate ganglion block (SGB) on VA burden and defibrillation episodes in patients with treatment refractory VAs. METHODS: Relevant studies from January 1960 through May 2017 were identified in PubMed and Google Scholar. We performed a patient-level analysis using Student's t-test to compare outcomes before and after SGB...

Buerger's disease is characterized by recurring progressive inflammation and occlusions in small and medium arteries and veins of the limbs. Its cause is unknown, but it is most common in young men with a history of tobacco use. It is responsible for ischemic ulcers and extreme pain in the hands and feet. In many cases, notably in patients with the most severe presentations, there is no possibility of improving the condition with surgery (limb revascularisation), and therefore, alternative therapies (e.g. sympathectomy) is used...

The nervous system plays a profound regulatory role in maintaining appropriate immune responses by signaling to immune cells. These immune cells, including B- and T-cells, can further act as intermediary messengers, with subsets of B- and T-cells expressing choline acetyltransferase (ChAT), the enzyme required for acetylcholine (ACh) synthesis. Neural control of ACh release from ChAT+ T-cells can have powerful immune implications, regulating lymphocyte trafficking, inflammation, and prevent death due to experimental septic shock...

BACKGROUND: Vagus nerve stimulation is currently clinically evaluated as a treatment for inflammatory bowel disease. However, the mechanism by which this therapeutic intervention can have an immune-regulatory effect in colitis remains unclear. We determined the effect of intestine-specific vagotomy or intestine-specific sympathectomy of the superior mesenteric nerve (SMN) on dextran sodium sulfate (DSS)-induced colitis in mice. Furthermore, we tested the efficacy of therapeutic SMN stimulation to treat DSS-induced colitis in rats...

BACKGROUND: We present a case series of upper extremity fibromuscular dysplasia (UE FMD) consisting of 22 patients from two tertiary referral centers focusing on clinical presentation, diagnostic findings, and interventional outcomes. FMD is a noninflammatory, nonatherosclerotic arteriopathy that has a predisposition for middle-aged women. Involvement of the UE is thought to be rare. Patients with UE FMD can present with claudication or ischemia, or they can be incidentally diagnosed...

We examined whether glucagon-like peptide-1 (GLP-1) affects β-cell mass and proliferation through neural pathways, from hepatic afferent nerves to pancreatic efferent nerves via the central nervous system, in high-fat diet (HFD)-induced obese rats. The effects of chronic administration of GLP-1 (7-36) and liraglutide, a GLP-1 receptor agonist, on pancreatic morphological alterations, c-fos expression and brain-derived neurotrophic factor (BDNF) content in the hypothalamus, and glucose metabolism were investigated in HFD-induced obese rats that underwent hepatic afferent vagotomy (VgX) and/or pancreatic efferent sympathectomy (SpX)...

All patients (36 hands) with connective tissue disorders who underwent periarterial sympathectomy of the hand alone or in conjunction with vascular bypass at our institution between 1995-2013 were reviewed. The durable resolution of ulcers was significantly higher in patients treated by periarterial sympathectomy and bypass than in patients treated by periarterial sympathectomy alone. Although there were more digital amputations in patients treated by periarterial sympathectomy alone, the difference was not statistically significant...

INTRODUCTION: Facial hyperhidrosis (FH) may lead patients to a significantly impaired quality of life (QOL). Video-assisted thoracoscopic sympathectomy (VATS) is reserved for more severe cases refractory to common first-line agents. The aim of this study was to evaluate the efficacy of VATS for FH and to compare the results between patients with facial hyperhidrosis as main complaint (FHMC) and patients with facial hyperhidrosis as nonmain complaint (FHNMC). METHODS: This was a retrospective study based on medical chart analysis from March 2000 to January 2014: 40 patients with FHMC and 136 patients with FHNMC...

Existing experimental studies of the effect of sympathetic nerve fibers on bone marrow cells are based on the systemic administration of neurotoxic 6-hydroxydopamine. The method of global chemical sympathectomy has some serious disadvantages and could lead to questionable results. We describe a new method of local chemical sympathectomy of rat femoral bone marrow using guanethidine (Ismelin) delivery using an osmotic mini pump. Local guanethidine treatment for 14days led to complete elimination of sympathetic fibers in femoral bone marrow in contrast to bone marrow of contralateral or naïve femurs...

BACKGROUND: Periarterial sympathectomy is a proposed surgical treatment for patients with refractory Raynaud syndrome; however, there is debate regarding the indications and extent of dissection. Due to the segmental arterial sympathetic innervation, we favor an extended sympathectomy in concert with vein graft reconstruction of occluded vessels when necessary. The purpose of this study is to examine outcomes of extended periarterial sympathectomy in our patients. METHODS: A retrospective chart review was performed on 46 patients who underwent 58 periarterial sympathectomies (12 bilateral) since 1981...
