Objetivo: Determinar la frecuencia de agresividad y conducta antisocial en estudiantes universitarios con dependencia al teléfono móvil. Materiales y métodos: Se incluyeron 66 estudiantes universitarios entre 18 a 25 años (54,5 % eran mujeres). Los participantes completaron la escala Mobile Phone Problematic Use Scale para la dependencia del teléfono móvil y la escala del Inventario Multifásico de la Personalidad de Minnesota, versión 2-RF para comportamiento antisocial y la agresividad. Resultados: Se encontró dependencia del teléfono móvil en el 22,7 % de la muestra (punto de corte: percentil 80). Además, se observó una significación estadística (p <0.01) en 8 escalas del MPPI-2-RF, que incluían CR4, AG y AGGR-r, relacionadas con la agresión y el comportamiento antisocial. Conclusiones: Existe una relación entre la dependencia del teléfono móvil y las escalas de agresividad y comportamiento antisocial. Postulamos que la dependencia del teléfono móvil podría ser un factor criminógeno.

Introduction. Determining the postmortem interval is usually based on macroscopic-morphological criteria (cadaveric phenomena); some other objective methods are often difficult to access in daily practice; therefore we analyze the usefulness of the histopathological examination of the skin as a supplementary method for determining the postmortem interval. Materials and methods.  23 patients and 92 skin biopsies were analyzed. All samples were taken in a maximum time of 6 h postmortem. Biopsies were classified into 4 groups according to the postmortem interval, with 23 biopsies in each group: 1 (1 to 6 h.); 2 (25 to 30 h.); 3 (49 to 54 h.); 4 (73 to 78 h); 21 histological criteria were analyzed with Fisher test and principal component analysis. Results.  Skin biopsies of 23 corpses (mean age 51.6 years, 15 males and 8 females) were studied. 21 histological criteria were analyzed by Fisher test; statistical significance (p <0.001) with a reliability of 94.61% was achieved in 15 parameters. With the 15 selected parameters, a principal component analysis established that there were differences among the 4 analyzed groups. Conclusions. The skin histological changes may be used as a supplementary parameter in the forensic evaluation of the early postmortem interval.

Introduction: In the forensic identification of unidentifed corpses, several technological clinical tools are used in order to obtain data that may be relevant in the judicial investigation. One of them is the registration and documentation of tattoos. Tattoos are body modifications with marks on the skin made by impregnating the epidermis with various pigments forming diverse figures. Their presence plays a very important role in our society, as it is also in the study of forensic sciences. Case report: The naked corpse of an unidentified female was located in a sewage stream, in an advanced process of putrefaction, with no soft tissues on the face due to cadaveric anthropophagy. In the external inspection, several tattoos were located that made positive forensic identification possible. Discussion: Biometric features, scars, marks on the body and tattoos have been especially important at a legal and forensic level, their state of conservation persists even after an advanced state of cadaveric decomposition, they remain even after the loss of the superficial layers of skin Conclusions. With this report we demonstrate the usefulness of the exterior study of the corpse and inspection of tattoos in the identification of unidentified corpses.
