ABSTRACT

La reconstrucción posterior a una cirugía oncológica resectiva maxilar es todo un desafío. Debido a esto, existen diversas técnicas quirúrgicas cuyo objetivo apunta a mantener no solo la funcionalidad, sino también la estética facial, especialmente en el área del reborde infraorbitario. El injerto de hueso calvarial es una opción segura y versátil para realizar una reconstrucción primaria en el reborde infraorbitario. Esta técnica está indicada en aquellos pacientes en los cuales la resección cutánea y exenteración orbitaria no son necesarias. Por este motivo, a continuación, analizaremos este tipo de injerto a propósito de un caso clínico en el que se usó asociado a un colgajo pediculado de fascia temporoparietal.


Reconstruction after maxillary resective oncological surgery is a challenge. Because of this, there are many surgical techniques whose objective is to maintain not only function but also facial aesthetics, especially in the infraorbital rim area. The calvarial bone graft is a safe and versatile option to perform a primary infraorbital rim reconstruction. This technique is indicated in those patients in whom skin resection and orbital exenteration are not necessary. For this reason, we will now analyze this type of graft in relation to a case in which it was used associated with a temporo-parietal fascia flap.

ABSTRACT

Resumen Uno de los pilares fundamentales en el manejo de la pandemia por SARS-CoV2 es la detección temprana de la presencia del virus en pacientes. El método más utilizado es mediante hisopado nasofaríngeo para amplificar ácidos nucleicos mediante reacción en cadena de polimerasa (PCR). Las complicaciones asociadas a la técnica de hisopado aún no están completamente caracterizadas. Hasta ahora hay un caso reportado internacionalmente de fístula de líquido cefalorraquídeo poshisopado nasofaríngeo. Presentamos dos casos de fístula posterior a dicho examen: el primer caso un paciente de género femenino con sospecha de hipertensión intracraneal idiopática, cuya brecha se reparó quirúrgicamente; el segundo caso un paciente de género masculino con antecedente de hidrocefalia y meningitis neonatal que, al estudio por rinorraquia, se encuentra un meningoencefalocele en el receso frontal derecho, también reparado quirúrgicamente.


Abstract One of the cornerstones in the management of coronavirus pandemic is the early identification of virus presence in patients. The most used test is the nasopharyngeal swab, used to amplify nucleic acids through polymerase chain reaction. Complications with this test have not been completely characterized. Until now, only one international report of cerebrospinal fluid leak has been reported. We present two cases of leak after nasopharyngeal swab test: the first case corresponded to an adult feminine gender patient with suspected idiopathic intracranial hypertension, whose gap was surgically repaired; the second case adult male patient with medical history of hydrocephalus and neonatal meningitis who was further studied for rhinoliquorrhea that showed a meningoencephalocele occupying the right frontal recess.

ABSTRACT

Giant cell arteritis is the most common vasculitis in patients aged over 50 years. We report an 89-year-old woman with significant weight loss and persistent frontal-occipital headaches lasting two months. The neurological examination at admission identified a decrease in visual acuity of the left eye, paralysis of the third cranial nerve of the right eye and alterations of body motility without objective signs of damage of the motor or sensitive pathways. Magnetic resonance imaging showed changes of the temporal artery wall and in both vertebral arteries, as well as bilateral cerebellar and occipital ischemic lesions. The Doppler ultrasound of the temporal arteries was compatible with Giant cell arteritis. Treatment with steroids was started. While receiving oral prednisone, the patient suffered new infarcts of the posterior territory, documented with a CAT scan.

ABSTRACT

RESUMEN El síndrome de Susac (SS) es una enfermedad autoinmune microangiopática poco frecuente, caracterizada por la tríada clínica: encefalopatía, alteraciones visuales e hipoacusia. Es una entidad de prevalencia desconocida dado su difícil diagnóstico debido a que la mayoría de las veces no se presenta con la tríada clínica clásica, y, dado que presenta múltiples diagnósticos diferenciales. Se reporta un caso de SS presentado en el Hospital del Salvador, con descripción de sus manifestaciones clínicas, estudio y manejo inicial. Además de una revisión en la literatura sobre la variabilidad de los hallazgos clínicos y el manejo de esta patología.


ABSTRACT Susac syndrome (SS) is a rare autoimmune micronagiopathic disease, characterized by the clinical triad of, encephalopathy, visual impairment and hearing loss. It is a difficult entity to diagnose since most of the time it does not present itself with the classical clinical triad, and it may be confused with other differential diagnoses. One clinical case of a patient with SS is described, its clinical manifestations, diagnosis and initial treatment. In addition, a literature review about the multiple clinical findings and management of these disease.
