Spectrally tunable, temporally shaped parametric front end to seed high-energy Nd:glass laser systems.

We describe a parametric-amplification-based front end for seeding high-energy Nd:glass laser systems. The front end delivers up to 200 mJ by parametric amplification in 2.5-ns flat-in-time pulses tunable over more than 15 nm. Spectral tunability over a range larger than what is typically achieved by laser media at similar energy levels is implemented to investigate cross-beam energy transfer in multibeam target experiments. The front-end operation is simulated to explain the amplified signal's sensitivity to the input pump and signal. A large variety of amplified waveforms are generated by closed-loop pulse shaping. Various properties and limitations of this front end are discussed.

Esquistosomiasis vesical y en la población pediátrica. Reporte de un caso y revisión de la literatura / Bladder schistosomiasis in the pediatric population. Case report and literatur review

La esquistosomiasis es una enfermedad que afecta a más de 200 millones de personas a nivel mundial. Es poco frecuente en nuestro medio, estando sobre todo distribuida a lo largo de África, en algunas áreas del Oriente Medio, en el oeste de Asia y ciertas zonas de América Latina. Se estima que 88 millones de los infectados son menores de 15 años. La hematuria es el síntoma cardinal, y se debe sospechar en los pacientes provenientes de las áreas de riesgo (sobre todo África subsahariana). Presentamos el caso de un niño de 11 años, originario de Mali, que consultó por presentar durante un año macrohematuria monosintomática; se siguió nuestro método diagnóstico, evidenciando la enfermedad causante del proceso, estableciéndose tras ello la terapéutica pertinente. Se realiza a partir de ahí una revisión de la literatura de la patología que nos ocupa (AU)

Schistosomiasis is a prevalent disease affecting more than 200 million people world wide. Even though is an infrequent disease in our environment, it is endemic trough Africa, some Middle East areas, Western Asia and certain South American areas. There are approximately 88 million children, 15 years old or less, affected. Hematuria is the paramount symptom, and we should suspect this infection in patients who come from this risky area. We report an 11 year old boy, originally from Mali, who complaint about having approximately a year of gross hematuria, discussing the pertinent assessment and treatment.
