ABSTRACT
La vasculitis reumatoidea es un proceso inflamatorio poco frecuente que confiere una morbilidad y mortalidad significativa en pacientes con artritis reumatoidea (AR). Presenta una incidencia de 0,7 a 5,4% de los casos de AR y hasta un 40% de mortalidad a 5 años, siendo la manifestación extraarticular de mayor gravedad1,2. Se caracteriza por el desarrollo de vasculitis necrotizante; ocurre típicamente en pacientes masculinos con AR seropositiva de larga data, nodular y erosiva, tabaquistas y, en general, tiene mal pronóstico. Se presenta una serie de casos, paciente masculino y femenino con AR y manifestaciones extraarticulares, necrosis digital y compromiso multiorgánico, interpretados como cuadros de vasculitis reumatoidea, realizando tratamiento de referencia con inmunosupresores.
Rheumatoid vasculitis is a rare inflammatory process that confers significant morbidity and mortality in patients with rheumatoid arthritis (RA); it has an incidence of 0.7 to 5.4% of RA cases and up to 40% mortality at five years, making it the most serious of all the extra-articular manifestations of RA1,2. It is characterized by the development of necrotizing vasculitis, it typically occurs in male patients with long-standing seropositive RA, erosive nodular, smokers and generally has a poor prognosis. A series of cases is presented, male and female with RA and extra-articular manifestations, digital necrosis and multiorgan system involvement, interpreted as rheumatoid vasculitis, undergoing treatment with immunosuppressants.

Statins are frequently prescribed in clinical practice for their proven efficacy in prevention of cardiovascular and cerebrovascular diseases. Despite the recognized beneficial effects of this class of drugs, in recent years, many studies published in medical literature have shown a wide range of adverse effects as a consequence of this therapy, including the risk of peripheral neuropathy. The purpose of this article is to report a case in which clinical features consistent with multiple mononeuropathy probably secondary to use of pravastatin were observed. The case report is followed by a review of the relevant literature.
As estatinas são frequentemente prescritas na prática clínica por sua comprovada eficácia na prevenção de doenças cardiovasculares e cérebrovasculares. Apesar dos reconhecidos efeitos benéficos dessa classe medicamentosa, nos últimos anos, diversos estudos publicados na literatura médica vem evidenciando uma ampla variedade de efeitos colaterais como consequência desta terapia, incluindo o risco de neuropatias periféricas. O objetivo deste artigo é relatar um caso no qual foram observadas manifestações clínicas compatíveis com o diagnóstico de mononeuropatia múltipla sensitiva, provavelmente secundária ao uso de pravastatina. O relato de caso é acompanhando de uma revisão de dados pertinentes da literatura.

La parálisis aislada del tercer par craneal no es frecuente en los niños. Entre las causas que la originan se encuentran las congénitas, traumáticas, infecciosas, tumorales, vasculares, tóxicas y desmielinizantes. Se presenta un paciente de 3 años de edad con el diagnóstico de una oftalmoplejía aguda dolorosa del tercer par craneal, cuya etiología no se pudo demostrar. El cuadro clínico desapareció de forma espontánea y no ha presentado recurrencias después de 3 años de seguimiento. Se concluye que ante un paciente con parálisis del tercer par craneal es necesario realizar una exhaustiva evaluación con el propósito de precisar las diversas causas que la provocan
Isolated third cranial nerve palsy is not frequent in children. Among the causes are congenital, traumatic, infectious, tumoral, vascular, toxic and demyelinizing. This is the case of a 3-years old patient diagnosed with acute painful ophthalmoplegia of the third cranial nerve, in which etiology could not be proved. The clinical picture disappeared spontaneously and no recurrence has emerged after 3 years of follow-up. It was concluded that when dealing with a patient with third cranial nerve palsy, it is necessary to make a thorough assessment to precise over the different causes

Objetivo: presentar un caso de mononeuropatía hipertrófica localizada. Descripción: paciente de 39 años de edad, que presenta una historia de dolor intenso y progresivo, hipoestesia en la región tenar y déficit motor en la mano izquierda. El examen físico mostró atrofia hipotener, mano en garra cubital y signo de Tinel en el antebrazo (8cm distal a la epitróclea). Intervención: la IRM mostró una masa a lo largo del recorrido del nervio cubital en el antebrazo. Se sugirió entonces tratamiento quirúrgico. No se obtuvo registro de conducción nerviosa durante la estimulación intraoperatoria, por lo cual se resecó la zona de fascículos afectados y se reemplazó la lesión por injertos autólogos extraídos de nervio sural. El diagnóstico histopatológico fue dificultoso y después de varias revisiones se concluyó que se trataba de de una mononeuropatía hipertrófica localizada. Conclusión: la paciente se encuentra actualmente bajo seguimiento y está mostrando signos de mejoría de la anestesía junto a remisión completa del dolor.
The authors report the case of a 39 year-old female, who presented with 10 years history of intense progressive pain, hypoesthesia in hypotenar region and motor deficit in the left hand. The physical exam showed hypotenar muscles atrophy, "claw hand", and Tinels sign in the forearm (8 cm distal from the medial epicondyle). Magnetic resonance imaging showed a mass lesion along ulnar nerve path in the forearm. Surgical treatment was, then, suggested. Nerve conduction could not be registered during intra-operative stimulation. Microsurgical resection of the damaged nerve fascicles and sural nerve grafting were performed. Histopathological diagnosis was difficult and could only be confirmed as localized hypertrophic mononeuropathy after revision of the biopsied material. The patient is being followed up and she is showing signs of hypoesthesia improvement in addition to complete remission of the pain.
