Experience gained in the risk assessment (RA) of genetically engineered (GE) crops since their first experimental introductions in the early nineties, has increased the level of familiarity with these breeding methodologies and has motivated several agencies and expert groups worldwide to revisit the scientific criteria underlying the RA process. Along these lines, the need to engage in a scientific discussion for the case of GE crops transformed with similar constructs was recently identified in Argentina. In response to this need, the Argentine branch of the International Life Sciences Institute (ILSI Argentina) convened a tripartite working group to discuss a science-based evaluation approach for transformation events developed with genetic constructs which are identical or similar to those used in previously evaluated or approved GE crops. This discussion considered new transformation events within the same or different species and covered both environmental and food safety aspects. A construct similarity concept was defined, considering the biological function of the introduced genes. Factors like environmental and dietary exposure, familiarity with both the crop and the trait as well as the crop biology, were identified as key to inform a construct-based RA process.

OBJECTIVE: To determine the prevalence of voiding dysfunction (VD) in patients with persistent vulvovaginitis (PVV), and to evaluate the clinical response of PVV in the treatment of VD. PATIENTS AND METHODS: Girls four years or older who consulted for PVV for at least one month and who did not respond to general measures. A physical examination was performed with visual inspection and colposcopy; vaginal samples for culture and vaginoscopy were carried out. On every patient urodynamic studies were performed. Girls who were diagnosed with VD were treated. A pediatric gynecologist did the follow-up; a successful response was considered when inflammatory symptoms and vaginal discharge ceased. RESULTS: Twenty patients were included, mean age 8.6 years (range: 4.6-14 years); 75% prepubertal symptoms lasted for 1.8 years; 19 (95%) had urodynamia, 10 (52.6%) had an overactive bladder, 8 (42.1%) external bladder sphincter dyssynergia, 1 (5.2%) hypotonic bladder, and 13 (65%) showed improvement. CONCLUSION: VD is an important cause when considering the etiology of PVV.

Este trabajo expone en particular los resultados obtenidos, mediante la aplicación del SIG, en cuencas cordilleranas argentinas donde se utilizó para el cálculo de los parámetros de entrada del Sistema de Pronósticos Hidrológicos y también para realizar el análisis de los resultados. Se demostró que SIG es una herramienta potente tanto para los modelos de simulación hidrológica como para interpretar los procesos hidrológicos en diferentes áreas de las cuencas hidrográficas

Tumors of the nervous system are the third most common malignant disease in Cuban children, after leukemia and lymphoma. In 138 patients with the diagnosis of brain tumor results of treatment by surgery and radiation were studied. The survival rate at 1, 3 and 5 years was 50, 40 and 37.6%. The best results were achieved in astrocytomas, mid grain and brain stem tumors and oligodendrogliomas.
