Ortner's syndrome, also known as cardiovocal syndrome, is a rare cause of hoarseness due to compression of the left recurrent laryngeal nerve caused by pathology of cardiovascular structures in the mediastinum. It was first described by Norbert Ortner in 1897, who associated the syndrome with mitral stenosis. It typically presents as paresis of the left recurrent laryngeal nerve, which is mechanically compressed in the area of the aortic arch.

A 68-year-old woman were admitted with chief complaints of persistent hoarseness, dysphagia and dyspnea on effort. She was found to have a left atrial myxoma with obstruction of mitral inflow on echo-cardiogram. The tumor was extensively attached to the atrial septum and left atrium.

Multisystem inflammatory syndrome in children (MIS-C) is a rare condition following SARS-CoV-2 infection associated with intestinal manifestations. Genetic predisposition, including inborn errors of the OAS-RNAseL pathway, has been reported. We sequenced 154 MIS-C patients and utilized a novel statistical framework of gene burden analysis, "burdenMC," which identified an enrichment for rare predicted-deleterious variants in BTNL8 (OR = 4.

Ortner's syndrome or cardiovocal syndrome is a rare condition referring to laryngeal recurrent nerve paralysis due to cardiovascular conditions. We report the case of a 66-year-old man, with a medical history of active smoking, who complained of hoarseness of voice secondary to vocal cord palsy. A neck and thoracic CT scan revealed severe enlargement of pulmonary main artery, which caused compression of the left recurrent laryngeal nerve in the aortopulmonary window The prolonged course of the left laryngeal nerve makes it susceptible to injury from cardiovascular structures in the mediastinum.

Article Synopsis
- A novel mutation (c.3506G>A, p.G1169D) in the Ca1.3 gene is linked to a syndrome that causes autism, developmental delays, and other neurological and hormonal disorders in children, presenting with varying severities.
- Two patients with this mutation exhibited different symptoms: one had severe issues including respiratory problems and hearing loss, while the other had a milder phenotype possibly due to mosaicism of the mutation.
- Functional studies showed that the mutation enhances channel activity, leading to abnormal calcium channel behavior, but treatments with calcium channel blockers (isradipine and nifedipine) did not produce positive effects for the severely affected patient.
