A picture can express something instead of having a thousand words that cannot do it. This phrase, which symbolically connotes a whole scheme of a signs system, is known as Semiotics. This paper presents the process of an educational video game development based on semiotic analysis. We used Extreme Programing Agile Methodology combined with a proposal of the modified Elemental Tetrad Game Design Model to develop a video game known as "Tic-Tac-Toe". The mathematical model was implemented with Artificial Intelligence algorithms and a graphical user interface including Semiotics; this was optimized for producing an enjoyable and interactive environment. With the purpose of stimulating cognitive development of children, this research combines theories about stimulating cognitive development of children; game design model, Semiotic Analysis harnesses the Model of Aleferenko, and uses algorithms based on heuristics and numerical methods in client-server architecture. The concept was tested with a representative sample of seven to eleven years old children. The results demonstrated that educational video games with Semiotics stimulate the cognitive development of children.
La leucemia de células dendríticas es una patología hematológica maligna rara, altamente agresiva, derivada de precursores de células dendríticas plasmocitoides. Se manifiesta con lesiones cutáneas e infiltración a médula ósea. Se presenta el caso clínico de un paciente masculino de 63 años de edad, quien presentó deterioro neurológico en contexto de uremia y leucocitosis con sospecha de leucemia aguda. Para la confirmación del diagnóstico requirió marcadores inmunológicos por citometría de flujo. Se identificó fenotipo compatible con leucemia/linfoma blástico de célula dendrítica plasmocitoide. Se inició un régimen de quimioterapia esquema 7+3, basado en citarabina 338 mg + 500 ml de NaCl 0,9 % en infusión intravenosa continua de 24 horas e Idarrubicina 20 mg + 250 ml de NaCl 0,9 % pasar IV en 2 horas. Recibió terapia de sustitución renal por 5 sesiones. El paciente pasó a estado crítico pese a tratamiento oncohematológico, presentó fallo multiorgánico y paro cardíaco. Se realizó reanimación cardiopulmonar avanzada de alta calidad, sin obtener retorno de la circulación espontánea y se declaró su fallecimiento. Se concluyó que esta neoplasia oncohematológica permite pocas expectativas de vida y los protocolos terapéuticos que mejoren la sobrevida son escasos.
