Resumen
The constants of motion of the following systems are deduced: a relativistic particle with linear dissipation; a no-relativistic particle with a time explicitly depending force; a no-relativistic particle with a constant force and time depending mass; and a relativistic particle under a conservative force with position depending mass. The Hamiltonian for these systems, which is determined by getting the velocity as a function of position and generalized linear momentum, can be found explicitly at first approximation for the first system. The Hamiltonians for the other systems are kept implicitly in their expressions for their constants of motion.

We report a newborn female with trisomy 18 associated to ichthyosis vulgaris of unusual congenital onset. Case report. The proposita born from a preterm pregnancy and presented also birth hypotrophy. Prenatally exposure to anesthesics, analgesics, antibiotics and antiacid drugs. Initial feeding problems were observed. Physical findings consisted in craniofacial dismorphy, congenital heart disease, besides contractural, genitalia and dermatoglyphic anomalies. Chromosomal studies showed 47XX, +18 as a regular finding. Her dermatosis, located on lower extremities extensor surfaces was clinically and histopathologically considered as ichthyosis vulgaris. The patient expired at 37 days of extrauterine life due to multiple organic failures. Conclusion. Trisomy 18 was considered advanced maternal age related and ichthyosis most probably to a autosomal dominant spontaneous mutation. Differential diagnosis of autosomal dominant and X-linked ichthyosis were included. Since occurrence of both events in the same patient is about 1:2,000,000, this observation most probably corresponded to a previously undescribed association.",,,,,,,,,"http://hdl.handle.net/20.500.12104/40299","http://www.scopus.com/inward/record.url?eid=2-s2.0-0029613824&partnerID=40&md5=06141caf48d0f2cee65eac34f84de4cf",,,,,,"10",,"Boletin Medico del Hospital Infantil de Mexico",,"591 595",,"52",,"Scopus",,,,,,"autosomal dominant ichthyosis vulgaris; Edwards syndrome; trisomy 18; X-linked ichthyosis",,,,,,"Congenital ichthyosis vulgaris in a patient with trisomy 18 [ICTIOSIS VULGAR CONGENITA EN UNA PACIENTE CON TRISOMIA 18]",,"Article"
