[Flumazenil, a benzodiazepine antagonist, in endoscopic premedication]. / Experiencia con flumazenil, antagonista de las benzodiapezinas, en premedicación endoscópica.

Midazolam is the benzodiazepine recommended for anaesthesia induction when an early recovering is desirable. Flumazenil, which is also a hydrosoluble imidazobenzodiazepine, improves the safety of the forhere one because it immediately reduces the degree of sedation. With this purpose, this last drug has been studied in 25 patients who had been previously treated with Midazolam in order to carry out different endoscopic studies. The Flumazenil average dose used was 0.276 mg and the conscience recovering after its intravenous injection, evaluated by a simple oral numeric regression test, oscillated between 60 and 300 seconds with an X of 96 seconds. Once the study was finished, all patients were discharged from hospital after two-hour observation, except for one patient (4%) who suffered a complication and so was discharged after a twenty-four-hour control. No doubt the advent of a drug opposed to benzodiazepine receptors used in anaesthetic induction shows the possibility of a quick recovering and moreover. Quicker discharge from hospital.

[Diagnostic value of tumor markers in pleural effusions]. / Utilidad diagnóstica de los marcadores tumorales en exudados pleurales.

In order to discriminate between benign and malignant effusions, the value of alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA) and beta subunit of human chorionic gonadotropin (GNCH Sub-beta) has been estimated in pleural exudates. A sample of 65 patients, 33 with a malignant (histologically and/or cytologically established) and 32 with a benign effusion was analysed. Only mean CEA in malignant effusions was significantly higher than in benign effusions (p less than 0.01). In the detection of malignant effusion CEA showed a sensitivity of 57% and a specificity of 97%; AFP a sensitivity of 9% and a specificity of 97% and GNCH Sub beta a sensitivity of 9% and a specificity of 90%.

Utilidad diagnostica de los marcadores tumorales en exudados pleurales / Diagnostic value of tumor markers in pleural effusions

Se estudiaron 65 pacientes con derrame pleural cuyo análisis físico-químico demostró la presencia de exudado, con la finalidad de valorar la utilidad de la alfa-fetoproteina (AFP), el antígeno carcinoembrionario (CEA) y la gonadotrofina coriónica humana subundad beta (GNCH Sub-ß) como marcadores tumorales. A todos los pacientes se les realizó estudio citolófico, físico, químico, bacteriológico y dosaje de los marcadores mencionados en el líquido pleural, llegándose al diagnóstico de origen neoplásico del mismo en base a la citologia y/o biopsia pleural. Los pacientes fueron divididos en dos grupos: 1) 33 neoplásicos y 2) 32 no neoplásicos. El CEA fue el único marcador tumoral significativamente más elevado en los derrames pleurales neoplásicos que en los no neoplásicos (p < 0,01). en relación al valor de estos marcadores como métodos de detección del origen neoplásico de un exudado pleural, se halló que el CEA tuvo una sensibilidad del 57% y una especialidad del 97%, la AFP una sensibilidad del 9% y una especificidad del 97% y la GNCH Sub-ß una sensibilidad del 9% y una especificidad del 90%
