ABSTRACT
OBJECTIVE: Capillary blood gas test has had ample use in the infantile population. In the adult population, the information is limited and controversial. The agreement between capillary-arterial gases seems to parallel the pH and the carbon dioxide pressure in different studied populations. In order to know the degree of agreement between these gases, we evaluate them at breathing room air and at 100% of oxygen fractions at 2,240 meters above sea level. METHODS: We obtained capillary-arterial blood gases simultaneously from subjects with stable cardiopulmonary disease in both conditions of inspired oxygen. Demographic, hemodynamic, diagnostic, and laboratory variables were gathered. Statistical analysis: agreement was analyzed with the intraclass correlation coefficient and the Bland-Altman procedure. RESULTS: We studied 101 subjects, 48 men and 53 women, whose respective ages were 55 +/- 16 and 56 +/- 16. Mean systemic arterial pressure was 94.96 +/- 10.57 mmHg. Hemoglobin was 15.94 +/- 2.48 g/dl. The agreement between the variables with the inspired oxygen fractions, 21%, 100%, and the mean difference in parenthesis was respectively: potential hydrogen, 0.94 (0.0091), 0.94 (0.0039); oxygen pressure, 0.90 (2.94), 0.84 (74.99); carbon dioxide pressure, 0.97 (0.079), 0.97 (0.179); bicarbonate, 0.93 (-0.067), 0,96 (0.262); total dissolved carbon dioxide, 0.94 (-0.142), 0.93 (0.161); base excess: 0.94, (-0.125), 0.92 (0.235); oxygen saturation, 0.98 (0.764), 0.97(0.202). CONCLUSIONS: Capillary blood gas test could be a useful alternative to the arterial one, nevertheless, it is limited by its low agreement with the oxygen pressure in both oxygen inspired fractions.

El Herpes Zóster es una infección producida por el virus Varicela - Zoster, siendo el único virus herpes capaz de producir dos cuadros diferentes: Varicela, como una enfermedad eruptiva de la infancia y Zóster, como una virosis de la edad adulta o de la senectud. En nuestro país, ha sido un problema poco estudiado y no se cuenta con investigaciones que reflejen el comportamiento real en el Centro Dermatológico Nacional "Dr. Francisco José Gómez Urcuyo", se realizó un estudio descriptivo, de corte transversal, no probalilístico con el objetivo de determinar el comportamiento clínico y terapéutico del Herpes Zóster. El universo lo conformaron 721 pacientes que fueron atendidos por primera vez en la consulta externa con diagnóstico de Herpes Zóster, la muestra fue constituida por 614 pacientes en los que se encontraron todos los datos completos. Dentro de los principales resultados, 326 pacientes fueron del sexo femenino y 286 masculinos. La gran mayoría de los pacientes (94 porciento) procedían del área urbana y sólo un 6 porciento eraan del área rural. 270 (45 porciento) fueron mayores de 50 años...
