ABSTRACT
In this paper, the use of three liquid crystal displays (LCDs) as targets for an experimental corneal topographer is proposed. The main advantage is that the geometrical pattern in the target can be modified without moving any mechanical part to apply the dynamic point shifting (DyPoS) method. Some results on the capabilities of the LCDs, obtained with photo frames, for measuring a 6.37 mm radius of curvature calibration sphere, and applying the DyPoS method, are presented. It is shown that the error in measuring the radius of curvature with DyPoS is reduced to 3% of the real value and the RMS in elevation or sagitta differences is around 15 µm, 30% or 66% of the values obtained without DyPoS, respectively.

To study the concentration of the proteine alpha-2 macroglobulin and caeruloplasmin in both sexes. Material.- 50 subjects were studied, 25 healthy men and 25 healthy women. They were between 20 and 40 years old. Results. The seric concentration of alpha-2 macroglobulin and caeruloplasmin was highest in the feminine sex than in the concentrations increase in pregnant women and in women who have oral contraceptives, it depends on the estrogenic medication (AU)

OBJECTIVE: To find the prevalence of flu vaccination and factors affecting the likelihood of being vaccinated. DESIGN: Observational, descriptive and cross-sectional study. SETTING: A district in Health Area III, Asturias, Spain. PARTICIPANTS: People of 65 and over selected by simple random sampling from the health card data base. The size of the sample was 386 users, of whom 326 agreed to take part. MAIN MEASUREMENTS: By means of a survey of our own design, conducted by phone interview, the variables gathered were social and personal details, accessibility, personal view of vaccination and attitude to it. A descriptive analysis and population estimates were made, with logistic regression used to identify associated variables. RESULTS: A 70.6% (95% CI, 65.9-75.2) of the population under study had been vaccinated. The main arguments for non-vaccination were: "don't want to" (35.5%; 95% CI, 25.8-45.2) and enjoyment of good health (34.4%; 95% CI, 24.8-44); 25% (95% CI, 19-30) of the elderly with some chronic pathology were not vaccinated; 92.3% (95% CI, 89.6-95) of those surveyed said they had not been contacted by their Health Centre; 35.7% (95% CI, 30.7-40.7) thought they would catch the flu the same if they were vaccinated; 41.6% (95% CI, 36.6-46.6) did not think so. Logistic regression showed positive association of vaccination and belief in its use (OR=338; 95% CI, 4.48-25084). CONCLUSIONS: Vaccination coverage in our health district was higher than that found by other studies and matched the figures stated in the programme record system. Raising awareness of the usefulness of vaccination is a strategy to be assessed in relation to increased coverage. We could not show that active phone recruitment affects vaccination at all.

Objetivo. Conocer la prevalencia de la vacunación antigripal y los factores implicados en la probabilidad de vacunarse. Diseño. Observacional, descriptivo y transversal. Emplazamiento. Una zona básica de salu (ZBS) del Área Sanitaria III de Asturias. Participantes. Personas ≥ 65 años seleccionadas por muestreo aleatorio simple a partir de base de datos de la tarjeta sanitaria. El tamaño de la muestra fue de 386 usuarios, de los cuales aceptaron participar 326. Mediciones principales. Mediante un cuestionario de elaboración propia realizado a través de entrevista telefónica. Se recogen variables sociodemográficas, de accesibilidad, de opinión personal y actitud frente a la vacunación. Se realiza un análisis descriptivo y estimaciones poblacionales mediante el análisis de regresión logística para identificar las variables asociadas. Resultados. El 70,6 por ciento (intervalo de confianza [IC] del 95 por ciento, 65,9-75,2) de la población en estudio ha sido vacunada. Como principales argumentos para no vacunarse refieren: «no querer» en el 35,5 por ciento (IC del 95 por ciento, 25,8-45,2) y gozar de buena salud en el 34,4 por ciento (IC del 24,8-44). El 25 por ciento (IC del 95 por ciento, 19-30) de los ancianos con alguna enfermedad crónica no es vacunado. El 92,3 por ciento (IC del 95 por ciento, 89,6-95) de los encuestados refiere no haber sido contactado por su centro de salud. El 35,7 por ciento (IC del 95 por ciento, 30,7-40,7) considera que tiene la gripe igual aunque se vacune, y el 41,6 (IC del 95 por ciento, 36,6-46,6) opina que no. Al aplicar el análisis de regresión logística se observa que la creencia en la utilidad de la vacuna se asocia positivamente con la vacunación (odds ratio = 338; IC del 95 por ciento, 4,48-25084). Conclusiones. La cobertura vacunal en nuestra ZBS es más elevada que la recogida en otros estudios y se ajusta a las cifras declaradas por el sistema de registro del programa. La sesibilización respecto a la utilidad de la vacuna sería una estrategia que se debería valorar en relación con el incremento de las coberturas. No hemos podido demostrar que la captación telefónica activa posea alguna influencia sobre la vacunación.(AU)

Se aportan tres casos de carotenodermia dietética tras la ingestión abundante de alimentos ricos en carotenos (zanahorias, naranjas). Se trata de dos varones y una mujer, adultos jóvenes, dos de ellos con antecedentes psicopatológicos. El principal problema clínico que plantean es la posible confusión con ictericias, aunque la pigmentación es sólo cutánea, no de escleróticas, la tonalidad es amarillo-anaranjada y la determinación de bilirrubina normal. La confirmación del diagnóstico se hace por la cuantificación de carotenos, que están elevados (AU)
There are three cases of dietetic carotenodermia after the great ingestion of food which is rich in carotenoids (carrot, oranges). There are two men and a woman, they are young adults, two of them have previous psicopathologics. The main clinic problem which appears is the possible mistake with icterics, although the pigmentation is only in this case skin, the pigmentation is not of eschlerotics, the shade of the skin is yellow- orange and the determination of normal billirubin. The confirmation of the diagnostic is made by the quantification of carotenes which are raised (AU)
