Background: Diabetic neuropathy (DN) is a heterogeneous condition characterized by complex pathophysiological changes affecting both autonomic and somatic components of the nervous system. Inflammation and oxidative stress are recognized contributors to the pathogenesis of DN. This study aims to evaluate the therapeutic potential of dichloroacetic acid (DCA) in alleviating DN symptoms, focusing on its anti-inflammatory and antioxidant properties.

The purpose of this study was to clarify sex differences in the inhibition of sympathetic vasomotor outflow which is caused by the loading of cardiopulmonary baroreceptors. Ten young males and ten age-matched females participated. The participants underwent a passive leg raising (PLR) test wherein they were positioned supine (baseline, 0º), and their lower limbs were lifted passively at 10º, 20º, 30º, and 40º.

Lambert-Eaton myasthenic syndrome (LEMS) is an autoimmune neuromuscular junction disorder characterized by proximal weakness, autonomic dysfunction, and areflexia associated with antibodies against voltage-gated calcium channels (VGCCs). Psychotic symptoms can occur in many autoimmune neurological disorders but they have rarely been observed in myasthenic syndromes. We report the case of a 21-year-old woman with primary autoimmune LEMS due to anti-VGCC antibodies subtype P/Q, who developed psychotic symptoms 3 years after the onset of motor symptoms.

Management of refractory ventricular fibrillation (VF) in patients with implantable implantable cardioverter defibrillator (ICD) presents a therapeutic challenge. We present a case of pediatric refractory ventricular tachycardia (VT)/Torsade de Pointe managed effectively with bilateral stellate ganglion block (SGB) with a long-acting local anesthetic for 18 days as a bridge to more definitive surgical management.

Background: Central synucleinopathies, including Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), involve alpha-synuclein accumulation and dopaminergic cell loss in the substantia nigra (SN) and locus coeruleus (LC). Pure autonomic failure (PAF), a peripheral synucleinopathy, often precedes central synucleinopathies.
Objectives: To assess early brain involvement in PAF using neuromelanin-sensitive magnetic resonance imaging (NM-MRI) and fluorodopa-positron emission tomography (FDOPA-PET), and to determine whether PAF patients with a high likelihood ratio (LR) for conversion to a central synucleinopathy exhibit reduced NM-MRI contrast in the LC and SN compared with controls and low-LR patients.
