Abstract: Objetivo: Evaluar la reducción del astigmatismo corneal preexistente en la cirugía de catarata mediante incisiones limbares relajantes (ILRs). Método: Estudio prospectivo de dos grupos de pacientes (tratamiento y control) con astigmatismo prequirúrgico ≥1D. Los 30 pacientes del grupo control fueron sometidos a facoemulsificación por incisión temporal en córnea clara y los 32 pacientes del grupo tratamiento a ILRs junto a facoemulsificación por incisión temporal en córnea clara. Se usó el test de Holladay para valorar la eficacia del tratamiento. Asimismo, presentamos un peque o estudio de la prevalencia y distribución del astigmatismo en nuestra población de trabajo. Resultados: El seguimiento promedio de los 62 pacientes fue de 3 meses, con un cambio astigmático medio a los 3 meses de -0.55D (-0,75 a -0,35) en el grupo tratamiento y de 0.04D (-0,3 a 0,3) en el grupo control (p<,000). Conclusiones: Las ILRs son un método sencillo y efectivo para conseguir reducir el astigmatismo previo durante la cirugía de catarata y con ello la dependencia de gafa.

Abstract: Caso clínico: Se presenta el caso de una paciente de tres a os de edad con neurofibromatosis tipo 1. La exploración oftalmológica reveló, mediante resonancia nuclear magnética, la presencia de un glioma de curso silente en el nervio óptico del ojo izquierdo. Discusión: La neurofibromatosis-1 produce múltiples manifestaciones en el campo oftalmológico, siendo los gliomas de la vía óptica los tumores del sistema nervioso central más frecuentes en la enfermedad. Por lo general suelen afectar al quiasma y su curso suele ser indolente, aceptándose un tratamiento conservador con seguimiento estrecho hasta que se detecte progresión.

Abstract: Caso clínico: Se presenta la evolución de un paciente con oftalmopatía de Graves (OG) tratado con análogos de la somatostatina, así como las indicaciones, pauta y resultados obtenidos. Discusión: Son pocas las opciones terapéuticas efectivas para el manejo de la oftalmopatía asociada a disfunción tiroidea de origen autoinmune. Los análogos de la somatostatina inhiben la proliferación y activación de los linfocitos, y se acumulan en el tejido orbitario durante la fase activa de la enfermedad oftálmica. Así, nos permitieron en el caso presentado llegar a la fase inactiva de la enfermedad sin secuelas importantes.

Abstract: Objetivo: Establecer una base de datos para el GDx-VCC representativa para nuestra población de entre 6 a 9 a os y analizar los datos obtenidos por rango de edades. Método: Se analizó la densidad de la CFN mediante oftalmoscopía de barrido con láser (GDx) a 116 ni os procedentes de un único colegio y los resultados fueron sometidos a estudio estadístico por edades y en global a fin de determinar el rango de valores considerable como la normalidad para esa población y las posibles diferencias entre ellos. Resultados: En el análisis global por cuadrantes de los datos estudiados por el GDx se encontró un promedio TSNIT de 59,43 (IC95% 58,41-60,45); superior de 71,35 (IC95% 69,99-72,70); inferior de 70,08 (IC95% 68,71-71,45) y una desviación estándar TSNIT de 25,11 (IC95% 24,36-25,86). En el análisis por edades se observan valores medios por cuadrantes comparables a los del global. Conclusiones: El estudio de la CFN mediante GDx se puede realizar sin problema en la población infantil de 6 a 9 a os dada la mínima colaboración requerida, obteniendo así datos objetivos sobre su estado y desarrollo durante estas edades.

Abstract: the phenomenon of immigration has had an impact on the health care of the population. the immigrant population in spain today represents approximately 8% of the total population. the majority of this population proceeds from countries with low income, and its origin and distribution is diverse. the immigrant population is characterised by its being young and healthy, and with a capacity to adapt to changes, but its social, economic and labour conditions are frequently insecure and favour vulnerability to disease. in spite of the number of immigrants of the male sex being globally higher than that of women, the percentage of immigrants of the female sex is growing. this increase of the female immigrant population has resulted in the appearance of specific health care needs, especially with respect to sexual and reproductive health. to which we must add a substantial increase in pathologies prevalent in the countries of origin, such as anaemia, tuberculosis, malnutrition, haemoglobinopathies, consanguinity, hypocalcaemia, hepatitis b and/or c, sexually transmitted infections, infectious diseases transmitted by arthropods, such as chagas disease and other parasitoses, as well as genital mutilations. the aim of this article is to analyse the factors that make it difficult to control gestation in the immigrant population, as well as to establish guidelines for acting in antenatal care consultations. insistence is placed on health education and prevention during pregnancy, and consideration is given to the appearance of rare diseases related to some of these groups.

Abstract: The phytochemical study of Uruguayan specimens of Allophylus edulis (Sapindaceae) yielded the isolation of various natural products being some of them reported for the first time in this species. Although most of them are ubiquitous in the plant kingdom, some revealed in this study to have anti insect properties. Two sesquiterpenes (6,7-Epoxicaryophyllene and spathulenol), two phytosterols (sitosterone and sitosterol), a pentacyclic triterpene (lupeol) and a clerodane diterpene were isolated. 6,7-Epoxycaryophyllene, lupeol and sitosterol showed to be deterrent against the aphid Myzus persicae and the coleopteran Epilachna paenulata. Moreover, the crude ethanolic extract of twigs of A. edulis showed to be deterrent against both insect species being some of its fractions also active against another aphid, Rhopalosiphum padi. Various active compounds against different insect models have been isolated from the twigs extract of A. edulis. The results evidenced synergic as well as antagonistic effects in the mixture, summed to differential activity against the insects, a desirable attribute when developing botanical pesticides.
