Bispectral index monitoring to detect delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage.

PURPOSE: Evaluate the bispectral index (BIS) monitoring to detect delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH). MATERIALS AND METHODS: A single-center prospective study in patients with aSAH. BIS monitoring was recorded during 25-120 min in two periods, within the initial 72 h (BIS1) and between days 4 and 6 (BIS2) from admission. The median for each exported BIS parameter was analyzed. Transcranial Doppler (TCD) sonography was simultaneously performed with BIS1 (TCD1) and BIS2 (TCD2) monitoring. A multivariate logistic regression model was built to identify the variables associated with DCI. RESULTS: Sixty-four patients were included and 16 (25%) developed DCI. During BIS2 monitoring, significant differences were found in BIS value (left, p = 0.01; right, p = 0.009), 95% spectral edge frequency (left and right, p = 0.04), and total power (left and right, p = 0.04). In multivariable analysis, vasospasm on TCD2 (OR 42.8 [95% CI 3.1-573]; p = 0.005), a median BIS2 value <85 in one or both sides (OR 6.2 [95% CI 1.28-30]; p = 0.023), and age (OR 1.08 [95% CI 1.00-1.17]; p = 0.04) were associated with the development of DCI. CONCLUSIONS: BIS value is the most useful BIS parameter for detecting DCI after aSAH. Pending further validation, BIS monitoring might be even more accurate than TCD.

Imaging Findings of Duodenal Duplication Cyst Complicated with Duodenal Intussusception and Biliary Dilatation.

Duodenal duplication cyst is an extremely rare congenital anomaly usually diagnosed in childhood. However, it may remain asymptomatic for a long period. In adults it usually manifests with symptoms related to complications as pancreatitis, jaundice, or intussusception. We present the radiology findings of a patient with a duodenal intussusception secondary to a duplication cyst. The usefulness of the magnetic resonance (MR) in this case is highlighted.

Pre-operative embolization of thyroid arteries in a case of refractory amiodarone-induced thyrotoxicosis. Case report / Embolización preoperatoria de las arterias tiroideas en un caso de tirotoxicosis refractaria por amiodarona. Reporte de caso

Abstract Introduction: Amiodarone has become one of the main antiarrhythmic drugs. However, it may cause a wide variety of adverse effects, sometimes severe. Amiodarone-induced thyroid dysfunction is one of the best known problems, resulting in either thyrotoxicosis or hypothyroidism. Case presentation: A patient who, after 2 years of using amiodarone for the control of atrial fibrillation, developed thyrotoxicosis, refractory to conventional medical treatment. To optimize the patient's clinical condition before total thyroidectomy, embolization of thyroid arteries was performed. Conclusion: Embolization of the thyroid arteries as bridge therapy to thyroidectomy is an uncommon alternative in patients with amiodarone-induced hyperthiroidism. However, this treatment was useful to improve our patient's symptoms and to optimize the anesthetic/surgical procedure.

Resumen Introducción: La amiodarona se ha convertido en uno de los principales fármacos empleados en el manejo de las arritmias cardiacas. Sin embargo, puede llegar a presentar una amplia variedad de efectos adversos, en ocasiones graves. La alteración de la función tiroidea es uno de sus problemas más conocidos, que puede causar tanto hipertiroidismo como hipotiroidismo. Presentación del caso: Se presenta el caso de un paciente que, después de recibir durante dos años amiodarona para el control de una fibrilación auricular, desarrolló una tirotoxicosis refractaria al tratamiento médico clásico, por lo que se decidió realizar una embolización de las arterias tiroideas previa a tiroidectomía total, para lograr una optimización preoperatoria de su situación clínica. Conclusión: La embolización de las arterias tiroideas como terapia puente a la tiroidectomía es una alternativa poco empleada en pacientes con hipertiroidismo, más aun si es debido a la administración de amiodarona, con escasos datos publicados en la literatura. En nuestro caso fue de utilidad para mejorar la sintomatología del paciente y optimizar el procedimiento anestésico-quirúrgico.

Bladder endometriosis and endocervicosis: presentation of 2 cases with endoscopic management and review of literature.

Urinary tract endometriosis and endocervicosis are an uncommon pathologic finding, with a common embryological origin. We present 2 cases of female patients with bladder mass. The first one was a finding of a nodular formation in the bladder during study of a nonviable foetus and the second was an incidental finding of a neoformation in the fundus of the bladder during the realization of an ultrasound. In both cases, we performed a surgical management with transurethral resection. Histopathological examination revealed a bladder endometrioma in the first case and endocervicosis with associated endometriosis in the second.
