Management of Harlequin Syndrome Under ECPELLA Support: A Report of Two Cases and a Proposed Approach

The use of ECPELLA in patients with severe lung disease may result in an unfavorable phenomenon of differential hypoxia. The simultaneous evaluation of three arterial blood samples from different arterial line (right radial artery, left radial artery, ECMO arterial line) in patients at risk of Harlequin syndrome (also called differential hypoxemia (DH)) can localize the 搈ixing cloud� along the aorta. Focusing the attention on the 搈ixing cloud� position instead of on isolated flows of Veno?Arterial Extracorporeal Membrane Oxygenation (VA ECMO) and Impella CP makes the decision making easier about how to modify MCSs flows according to the clinical context. Herein, we present two cases in which ECPELLA configuration was used to treat a cardiogenic shock condition and how the ECPELLA-induced hypoxia was managed.

Harlequin color change in a newborn who was positive for COVID-19: report of a case

Harlequin color change is a benign, idiopathic, self-limiting disorder characterized by the appearance of skin divided into two distinctly colored areas. Its etiology is unknown but thought to be caused by immaturity of hypothalamic regulation of peripheral vascular tone. COVID-19 infection in neonates is infrequent and rarely symptomatic, with only a few cases described in the literature. In isolation, both conditions have a low incidence. It is the first case reported in the world literature of harlequin color change in a newborn who tested positive for COVID-19. There isn't a single publication that links harlequin color change to COVID-19.

El cambio de color arlequín es un trastorno benigno, idiopático y autolimitado que se caracteriza por una apariencia de la piel dividida en dos zonas de color distinto. Su etiología es desconocida, pero se cree que está causada por una inmadurez hipotalámica del tono vascular periférico. La infección por COVID-19 en neonatos es infrecuente y raramente sintomática, con sólo unos pocos casos descritos en la literatura. De forma aislada, ambas afecciones tienen una baja incidencia. Este es el primer caso descrito en la literatura mundial de cambio de coloración arlequín en un recién nacido que dio positivo a COVID-19. Aun no existe ninguna publicación que relacione el cambio de color arlequín con COVID-19.

Harlequin syndrome: a case report / Síndrome de arlequín: reporte de un caso

El síndrome de Arlequín es una condición neurológica poco común, la mayoría de las veces benigna. Por lo general la mayor parte de los casos son de causa idiopática (aunque existen causas secundarias). Esta afección consiste en la aparición de eritema e hiperhidrosis facial unilateral desencadenado por el ejercicio, calor, emociones o estrés, la que se produce debido a una disfunción contralateral de la vía simpática vasodilatadora y sudomotora. Se presenta el caso de un paciente de sexo masculino de 49 años, que relata presentar un cuadro de 15 años de evolución caracterizado por la aparición de eritema y sudoración excesiva de la hemicara derecha, la cual termina abruptamente en la línea media de la cara, gatillado por el ejercicio y el calor en verano, mientras que la hemicara izquierda presenta anhidrosis sin eritema.

The Harlequin syndrome is a rare neurological condition, most of the time benign. In general, most cases are idiopathic (although there are secondary causes). This condition consists in the appearance of unilateral facial erythema and hyperhidrosis triggered by exercise, heat, emotions or stress, which occurs due to a contralateral dysfunction of the sympathetic vasodilator and sudomotor pathway. We present the case of a 49-year-old male patient, with no relevant morbid history, who reports a medical history of 15 years of evolution, characterized by the appearance of erythema and excessive sweating of the right side of his face, which ends abruptly in the middle line of the face, triggered by exercise and heat during the summer. While the left side presents anhidrosis without erythema.

Harlequin Syndrome Following Resection of Mediastinal Ganglioneuroma

Harlequin syndrome is a rare disorder of the sympathetic nervous system characterized by unilateral facial flushing and sweating. Although its etiology is unknown, this syndrome appears to be a dysfunction of the autonomic nervous system. To the best of our knowledge, thus far, very few reports on perioperative Harlequin syndrome after thoracic surgery have been published in the thoracic surgical literature. Here, we present the case of a 6-year-old patient who developed this unusual syndrome following the resection of a posterior mediastinal mass.

A pediatric case of idiopathic Harlequin syndrome / 소아과

Harlequin syndrome, which is a rare disorder caused by dysfunction of the autonomic system, manifests as asymmetric facial flushing and sweating in response to heat, exercise, or emotional factors. The syndrome may be primary (idiopathic) with a benign course, or can occur secondary to structural abnormalities or iatrogenic factors. The precise mechanism underlying idiopathic harlequin syndrome remains unclear. Here, we describe a case of a 6-year-old boy who reported left hemifacial flushing and sweating after exercise. He had an unremarkable birth history and no significant medical history. Complete ophthalmological and neurological examinations were performed, and no other abnormalities were identified. Magnetic resonance imaging was performed to exclude lesions of the cerebrum and cervicothoracic spinal cord, and no abnormalities were noted. His final diagnosis was classic idiopathic harlequin syndrome. Herein, we report the first pediatric case of idiopathic harlequin syndrome in Korea.

Síndrome disautonómico de Ross: variaciones de un tema / Disautonomic Ross syndrome: variations about one theme

El síndrome de Ross fue descrito en 1958 como una afección degenerativa del sistema nervioso autónomo definido por la tríada de anhidrosis generalizada, disminución de los reflejos tendinosos y pupila tónica. Desde su descripción inicial se han descrito cerca de cuarenta casos. Comunicamos tres pacientes con variantes de interés que incluyen la presencia de espasmos cíclicos espontáneos del esfínter de iris, el desarrollo conjunto de síndrome de Holmes-Adie en un lado y síndrome Horner posganglionar en el otro, trastornos del desarrollo piloso en el lado de la anhidrosis, alteraciones de la motilidad intestinal, lengua sin papilas gustativas y disfunción sexual.

Ross Syndrome was described in 1958 as a degenerative condition of the autonomic nervous system defined by a triad of generalized anhidrosis, reduction of tendon reflexes and tonic pupil. Since its initial description about 40 cases have been described. We communicate three cases with variants of interest involving the presence of the simultaneous development of syndrome of Holmes-Adie on one side and Horner syndrome in the other, disorders of pilous follicle development on the side of anhidrosis, spontaneous disturbances of intestinal motility, tonque without papillae and sexual dysfunction.

Harlequin Syndrome with Crossed Sympathetic Deficit of the Face and Arm

Harlequin syndrome is characterized by unilateral hyperhidrosis and flushing, which are predominantly induced by heat or exercise. Usually, the sympathetic deficits confine to the face. Rarely, the autonomic deficits involve the arm or the parasympathetic neurons in the ciliary ganglia. We report a 43-yr-old woman who presented with facial flushing and sweating in the right side, which were mainly induced by exercise. The facial flushing accompanied relative coldness in the right arm. Valsalva maneuver, cold pressure and 0.125% pilocarpine test, and computed tomography of the chest were normal. The crossed sympathetic deficit in the left face and right arm suggested that the lesions were multifocal. The sympathetic impairment in our patient may lie on a spectrum of pre- and postganglionic autonomic dysfunction, which was observed in Holmes-Adie, Ross, and Guillain-Barre syndrome.
