A 63-year-old male was diagnosed with autoimmune autonomic ganglionopathy based on the finding of plasma antibodies to the nicotinic acetylcholine receptor (nAChR) of autonomic ganglia. He complained of mouth and eye dryness, dysphagia, severe constipation, erectile dysfunction, urgency, frequent urination, habitual orthostatic syncope and presyncope. A remarkable symptomatic orthostatic hypotension without changes in heart rate was present. We here describe the 3-year time course of the changes in spectral indices of cardiovascular autonomic control LF/HF and LFSAP, dysautonomia symptoms intensity and anti-nAChR antibodies following repetitive selective immunoadsorptions...

PURPOSE OF REVIEW: Thoracic radiation therapy is an effective treatment for several malignancies, such as Hodgkin's lymphoma and breast cancer. Over the years, however, the incidence of cardiovascular events has increased in these patients, notably in younger survivors who do not have traditional risk factors. This review summarizes the pathology, incidence, clinical presentation, and management of cardiac events after radiation therapy. RECENT FINDINGS: Mediastinal radiation therapy accelerates the atherosclerosis process, resulting in early onset coronary artery disease...

BACKGROUND: Most patients with spinal cord injury (SCI) suffer from neurogenic lower urinary tract dysfunction (NLUTD), bowel dysfunction and sexual dysfunction. If these remain untreated, severe medical complications and serious limitations (restrictions) in quality of life are imminent. OBJECTIVES: In the long term, there are considerable differences in the treatment results of highly specialized centers versus other treatment facilities. MATERIALS AND METHODS: Against this background, a consensus-based guideline, according to the AWMF (Association of the Scientific Medical Societies in Germany) criteria (S2k), was developed by the neuro-urology working group of the DMPG (German-Speaking Medical Society of Paraplegia)...

REVIEW

Many pharmacological and psychological approaches have been found efficacious in patients with generalized anxiety disorder (GAD), but many treatment-seeking patients will not respond and others will relapse despite continuing with interventions that initially had beneficial effects. Other patients will respond but then stop treatment early because of untoward effects such as sexual dysfunction, drowsiness, and weight gain. There is much scope for the development of novel approaches that could have greater overall effectiveness or acceptability than currently available interventions or that have particular effectiveness in specific clinical subgroups...

RATIONALE: Slow transit constipation (STC) is a common disease of which the etiology is still not clear. Multiple hypotheses have been proposed to explain STC, including autonomic neuropathy, disorders of the enteric nervous system and so forth. Morphological abnormalities of the enteric nerves of the colon in patients with STC have been extensively reported, while there have been no morphological reports focusing on extrinsic extramural fibers from the pelvic plexus to the distal colon (i...

Cardiac hypertrophy is associated with autonomic imbalance, characterized by enhanced sympathetic activity and withdrawal of parasympathetic control. Increased parasympathetic function improves ventricular performance. However, whether pyridostigmine, a reversible acetylcholinesterase inhibitor, can offset cardiac hypertrophy induced by pressure overload remains unclear. Hence, this study aimed to determine whether pyridostigmine can ameliorate pressure overload-induced cardiac hypertrophy and identify the underlying mechanisms...

Intercellular communication among autonomic nerves, endothelial cells (ECs) and vascular smooth muscle cells (VSMCs) plays a central role in an uninterrupted regulation of blood flow through vascular contractile machinery. Impairment of this communication is linked to development of vascular diseases such as hypertension, cerebral/coronary vasospasms, aortic aneurism, and erectile dysfunction. Although the basic concept of the communication as a whole has been studied, the spatiotemporal correlation of ECs/VSMCs in tissues at the cellular level is unknown...

BACKGROUND: We hypothesized in this study that transcranial direct current stimulation (tDCS) of primary motor cortex could exert top-down modulation over subcortical systems associated with autonomic control and thus be useful to revert some of the dysfunctional changes found in the autonomic nervous system (ANS) of subjects with spinal cord injuries (SCI). OBJECTIVE: To explore the acute effect of tDCS on ANS indexed by Heart Rate Variability (HRV) in individuals with SCI and analyze whether this effect depends on the gender, degree, level and time of injury...

PURPOSE: Adults after surgical repair of tetralogy of Fallot (ToF) may have impaired vascular and cardiac autonomic function. Thus, we wanted to assess interrelations between heart rate variability (HRV) and heart rate recovery (HRR), as parameters of cardiac autonomic function, and arterial stiffness, as a parameter of vascular function, in adults with repaired ToF as compared to healthy controls. METHODS: In a case-control study of adults with repaired ToF and healthy age-matched controls we measured: 5-min HRV variability (with time and frequency domain data collected), carotid artery stiffness (through pulse-wave analysis using echo-tracking ultrasound) and post-exercise HRR (cycle ergometer exercise testing)...

RATIONALE: Hereditary amyloidosis is diagnosed worldwidely with an increasing incidence. As the most common form, transthyretin-related hereditary amyloidosis (ATTR amyloidosis) is an autosomal dominant inherited disease due to mutations of TTR. Over the past several decades, more than 130 mutations have been reported. Previous studies suggested that ATTR amyloidosis initially showed polyneuropathy and autonomic dysfunction but later involving many visceral organs, such as kidney. PATIENT CONCERNS: A young proband carrying TTR p...

Spinal cord injury (SCI) is characterised by profound respiratory compromise secondary to the level of loss of motor, sensory and autonomic control associated with the injury. This review aims to detail these anatomical and physiological changes after SCI, and outline their impact on respiratory function. Injury-related impairments in strength substantially alter pulmonary mechanics, which in turn affect respiratory management and care. Options for treatments must therefore be considered in light of these limitations...

BACKGROUND: Device interrogation has become a standard part of the syncope evaluation for patients admitted with permanent pacemakers (PPM) or implantable cardiac defibrillators (ICD), although few studies have shown interrogation yields clinically useful data. The purpose of this study is to determine the diagnostic yield of device interrogation as well as other commonly performed tests in the workup of unexplained syncope in patients with previously implanted PPMs or ICDs. METHODS: We retrospectively reviewed records of 88 patients admitted to our medical center for syncope with previously implanted pacemakers between January 1, 2005 and January 1, 2015 using ICD-9 billing data...
