Radiofrequency Ablation for Solitary Autonomously Functioning Thyroid Nodules: Multicenter Study from Latin America.

Autonomously functioning thyroid nodules (AFTNs) represent ∼5% of all thyroid nodules and often necessitate definitive treatments such as surgery or radioiodine (I), both of which have inherent risks. Radiofrequency ablation (RFA) has emerged as an effective and safe therapeutic option for managing AFTNs. This study aims to assess the effectiveness and safety of RFA for solitary AFTNs in various countries across Latin America.

Unilateral Horner's Syndrome and Upper Limb Paresthesia Following Labor Epidural Analgesia: A Case Report.

Horner's syndrome arises from a disruption in the sympathetic nervous system. Although it is an uncommon complication of labor epidural analgesia, its occurrence is significantly more frequent among pregnant women. The incidence of Horner's syndrome after epidural analgesia for labor is 0.

Unveiling the Uncommon: A Case Report of Horner's Syndrome as a Rare Glimpse Into Giant Cell Arteritis.

Giant cell arteritis (GCA) is an inflammatory vasculitis affecting large and medium-sized arteries, leading to complications such as arterial dissection, blindness, and stroke. Rarely, GCA presents with Horner's syndrome due to sympathetic neuron involvement from arterial inflammation. This case report discusses an 82-year-old female with hypertension, atrial fibrillation, and arthritis who presented with a 24 h history of right eye ptosis, blurred vision, dizziness, and aching eye pain.

CT-guided Left Stellate Ganglion Cryoneurolysis for Refractory Ventricular Arrhythmias.

Background Ventricular arrhythmias (VAs), including ventricular tachycardia and ventricular fibrillation, present substantial therapeutic challenges due to their high morbidity, mortality, and increasing prevalence. Current treatments often prove infeasible or inadequate in patients with refractory VAs. Purpose To evaluate the safety and effectiveness of CT-guided left stellate ganglion cryoneurolysis (SGC) in the treatment of refractory VAs.

Delayed Horner's syndrome and acute stress disorder caused by a large dog bite on the neck: Case report.

Rationale: The occurrence of delayed Horner's syndrome caused by a dog bite to the neck is rarely reported. Acute stress disorder (ASD) can easily be neglected when diagnosing this disease in trauma patients who cannot be effectively observed. The symptoms of Horner's syndrome may not be readily detected in patients with ASD.

Pupil sparing oculomotor nerve palsy with concomitant Horner syndrome as a presentation of mantle cell lymphoma relapse.

A woman in her 70s, with a background of mantle cell lymphoma (MCL), presented with headache and diplopia. Neuro-ophthalmic examination revealed a combination of Horner syndrome and ipsilateral pupil sparing oculomotor nerve palsy (ONP). Cerebrospinal fluid immunophenotyping demonstrated CD5 positive clonal B lymphocytes, consistent with neurological involvement by MCL.

Application of microsurgical surgery in patients with proximal vertebral artery stenosis unsuited for endovascular treatment: a single-center retrospective study.

To investigate the clinical efficacy and safety of microsurgical surgery in patients with proximal vertebral artery stenosis unsuitable for endovascular treatment. A retrospective analysis was conducted on the clinical data of 34 patients with proximal vertebral artery stenosis who underwent microsurgical surgery at the Department of Cerebrovascular Surgery, Shengli Oilfield Central Hospital, Dongying, Shandong, from March 2020 to April 2023. Preoperative imaging confirmation of proximal vertebral artery stenosis or occlusion was obtained using cervical CT angiography (CTA), CT perfusion imaging (CTP), and magnetic resonance angiography (MRA).

Perioperative and long-term outcomes of bilateral cardiac sympathetic denervation via video-assisted thoracoscopic surgery in patients with refractory ventricular arrhythmias.

Background: Bilateral cardiac sympathetic denervation (CSD) performed via video-assisted thoracoscopic (VAT) surgery shows potential in managing ventricular tachycardia (VT), thereby reducing arrhythmic burden. In this setting, the scarcity of studies addressing both perioperative and long-term outcomes creates a substantial gap in the optimal management of patients with multiple comorbidities and limited treatment options. This observational study aimed to assess the medical comorbidities, as well as the short- and long-term outcomes of patients who underwent CSD for VT refractory to catheter ablation and medical therapy at a referral tertiary teaching hospital.

Anatomical and histological classification of the stellate ganglion: implications for clinical nerve blocks.

Purpose: The stellate ganglion (SG), or cervicothoracic ganglion, is usually located anterior to the neck of the first rib. Various techniques, such as ultrasonographic imaging and fluoroscopic approaches, are used to assist in the anesthetic blockade of the SG. However, there are reported complications associated with SG block; some patients had medication-related or systemic side effects, and some had procedure-related or local side effects.

Recovery of the Total Birth Brachial Plexus Palsy without Surgical Treatment: A Single-Center, Retrospective Study and Literature Review.

 Spontaneous recovery of a birth brachial plexus disorder is difficult to predict. Although root avulsion and total plexus injury is indicated for surgical management, early nerve surgery is still doubtful. Hand motion is obviously an important indicator for predicting the function of an affected limb.

Differentiation of Horner Syndrome and Physiological Anisocoria by Automated Pupillometry.

Background: The differentiation of Horner syndrome from physiological anisocoria is important yet clinically challenging. We investigated the diagnostic accuracy of pupillometry to discriminate Horner syndrome from physiological anisocoria compared to pharmacological testing with the alpha-2-agonist apraclonidine, which is considered the current gold standard.

Methods: Forty-four adult patients, mostly referred to our neuro-ophthalmology service for evaluation of anisocoria, were included.

Horner's syndrome caused by the first rib fracture sustained during coronary artery bypass grafting: a case report and literature review.

Background: Horner's syndrome is a rare complication of cardiovascular surgery. A bone fragment and hematoma due to rib fracture after cardiac surgery may cause injury to the brachial nerve plexus and sympathetic nerve trunk, leading to neurologic disorders and Horner's syndrome. However, few reports have revealed the etiology of Horner's syndrome after cardiovascular surgery based on imaging.

Horner Syndrome Secondary to Rapid Enlargement of a Mediastinal Lymphatic Malformation.

Horner syndrome is a clinical triad of ptosis, miosis, and anhidrosis, which commonly prompts urgent neuroimaging. The differential diagnosis of new-onset Horner syndrome in children includes neurological emergencies. We report here a case of a 13-month-old male infant with acute-onset Horner syndrome, subsequently found to have a large mediastinal lymphatic malformation compressing the trachea and neck vasculature.

Upper Extremity Blocks for Hand Surgeons: A Literature Review of Regional Anaesthesia Techniques, Efficacy, and Safety.

Regional anaesthesia (RA) techniques have increased in popularity due to evidence of reductions in acute pain, chronic pain, postoperative nausea and vomiting (PONV), and pulmonary complications. While upper extremity blocks (UEBs) have been the subject of several comprehensive reviews, no review to date has synthesised the information on their use in hand surgery. A search of PUBMED and Cochrane databases was performed to identify the evidence associated with upper extremity blocks.
