ABSTRACT
The three classic symptoms of carotid cavernous fistula (CCF) are pulsating exophthalmos, bruit and conjunctival chemosis. Here, we present a clinical case of isolated abducens nerve palsy due to a high-flow CCF in an 84-year-old woman, without the typical congestive orbito-ocular features. It was a diagnostic challenge because, for patients older than 50 years with cardiovascular risk factors, ischaemic mononeuropathy is the most frequent aetiology. This case illustrates the least common type of CCF that can be easily misdiagnosed. Physicians should consider fistula as a possible diagnosis in a patient with isolated abducens nerve palsy even without the classic triad.
ABSTRACT
INTRODUCTION: Stroke (CVA) in young adults comprises approximately 10% of all cerebrovascular events. The information available on the recurrence of a new event in this population and particularly in Latin America is limited. Our objective was to examine the presence of stroke recurrence after having presented a stroke. METHODS: A retrospective cohort study was carried out, including patients with arterial cerebral infarctions between the ages of 18 and 55, between January 2005 and May 2020. The main outcome was the recurrence of a cerebrovascular attack. RESULTS: 138 patients were included during a median follow-up of 24 months. The 52.2% (n = 72) were male patients and 73.4% (n = 94) had an initial NIHSS score of less than 4. The 38% (n = 52) had a history of arterial hypertension and 13, 1% (n = 18) history of previous stroke / TIA. 13% (n = 18) presented recurrence during their follow-up. DISCUSSION: The recurrence of neurovascular events occurs predominantly in patients with a history of previous stroke/TIA, probably secondary to diseases that are difficult to diagnose.
Introducción: El ataque cerebral (ACV) en adultos jóvenes comprende aproximadamente el 10% de todos los eventos cerebrovasculares. La información disponible sobre la recurrencia de un nuevo evento en esta población y particularmente en Latinoamérica es limitada. Nuestro objetivo fue examinar la presencia de recurrencia de ACV luego de haber presentado un infarto cerebral. Métodos: Se realizó un estudio de cohorte retrospectivo, incluyendo pacientes con infartos cerebrales arteriales en edades comprendidas entre 18 y 55 años, entre enero de 2005 a mayo de 2020. El resultado principal fue la recurrencia de un ataque cerebrovascular. Resultados: Se incluyeron 138 pacientes durante una mediana de seguimiento de 24 meses. El 52.2% (n = 72) de sexo masculino y el 73,4% (n = 94) tuvo un NIHSS inicial menor a 4. El 38% (n = 52) tenía antecedentes de hipertensión arterial y 13,1% (n = 18) antecedentes de ACV / ataque isquémico transitorio (AIT) previo. El 13% (n = 18) presento recurrencia durante su seguimiento. Discusión: La recurrencia de los eventos neurovasculares ocurren predominantemente en pacientes con antecedentes de ACV/AIT previo, probablemente secundario a enfermedades de difícil diagnóstico.

Erythromelalgia is a rare syndrome characterised by recurrent erythema, heat and burning pain in the extremities. There are two types: primary (genetic) and secondary (toxic, drug-related or associated with other diseases). We report a 42-year-old woman who developed erythromelalgia after taking cyclosporine for myasthenia gravis. Although exact mechanism for this rare adverse effect is unclear, it is reversible, and so clinicians should be aware of the association . Additional use of corticosteroids could aggravate cyclosporine's toxic effects.
