Estenosis congénita aislada del conducto auditivo interno como causa de hipoacusia neurosensorial unilateral y paresia del nervio facial / Congenital internal auditory canal stenosis presenting with unilateral sensorineural hearing loss and facial nerve dysfunction

RESUMEN La estenosis del conducto auditivo interno con aplasia/hipoplasia del nervio cocleovestibular es una patología muy infrecuente. Suele ser unilateral y puede acompañarse de aplasia/hipoplasia del nervio facial y otras malformaciones del oído interno. Se presentan aquí dos casos clínicos de pacientes pediátricos con estenosis del conducto auditivo interno unilateral con compromiso del séptimo y octavo par craneal ipsilateral. Se describen las historias y evaluaciones clínicas, hallazgos audiovestibulares, hallazgos imagenológicos, tratamientos indicados y sus resultados.

ABSTRACT Congenital internal auditory canal stenosis associated with aplasia/hypoplasia of the cochleovestibular nerve is a very infrequent pathology. It is usually unilateral and may be accompanied by aplasia/hypoplasia of the facial nerve and other malformations of the inner ear. We hereby present two clinical cases of pediatric patients with congenital internal auditory canal stenosis, with involvement of the seventh and eighth ipsilateral cranial nerve. The medical histories and clinical evaluations, audiovestibular findings, imaging findings, treatments and their results are described.

Uso del sistema POPQ para la clasificación de los prolapsos: Hospital Parroquial de San Bernardo / Use of the POPQ system for prolapses classification: Hospital Parroquial de San Bernardo

El sistema de Pelvic Organ Prolapse Quantification (POPQ) ha demostrado ser útil, fácil de aprender, rápido de realizar y con una buena confiabilidad intra e interobservador. Quisimos comenzar a aplicar este tipo de clasificación y compararla con la clasificación clásica de Baden y Walker descrita en la ficha clínica. Para esto se realizó un estudio observacional de 41 pacientes en que se comparó el sistema tradicional consignado en la ficha, con la medición de nueve puntos que utiliza el sistema POPQ. En 17 por ciento de los casos ambos sistemas coincidieron en el diagnóstico del descenso de todos los elementos del prolapso: pared anterior, posterior y cuello uterino. El sistema POPQ permite un diagnóstico acabado del estado y magnitud del descenso de los órganos pelvianos.

The Pelvic Organ Prolapse Quantification (POPQ) System has proved to be a good method for describing and quantifying pelvic organ prolapse. The objective of this observational study was to compare the classification consigned in the clinical records (Baden and Walker classification) with the new POPQ system. In the first 41 cases we proceed to evaluate our patients by mean of the POPQ system. In only 17 percent of the cases the two systems agreed in the diagnosis of the anterior, posterior and cervix descents. POPQ system allows an acute diagnosis of the state and magnitude of the descent of pelvic organs.

A propósito de la muerte de Cano de Aponte y los accidentes ecuestres / On the death of Gabriel Cano de Aponte

Gabriel Cano de Aponte was Governor of Chile since 1717 and util his death in 1733, being 68 years old. As a soldier, he was an experimented horse rider. The sequence ofevents that caused his death three months after an equestrian accident are unclear. A systematic clinical analysis of the later is the main objective of this review. Historians have documented Cano de Aponte's "inclination for unbridled fun and equestrian exercises". During a holiday Cano de Aponte suffered a horse fall and subsequent crushing by the latter. It has been stated that a spinal lesion caused by the accident kept him bedridden for a period of three months, clear in reason and with intense pain, before his death. However, there is no evidence on historie data that conveys any typical sign associated to spinal injury following the accident. Therefore we suggest that Cano de Aponte suffered a complex pelvic ring fracture. The fact that he was prostrated, lucid, but suffered and intense pain best sustains the hypothesis of a pelvic fracture. After the initial period, one ofthe most common causes of death resulting from a pelvic fracture is deep venous thrombosis with secondary pulmonary thromboembolism. This must have been the sequence ofevents that most probably caused Cano de Aponte's death).
