RESUMO
Abstract Submental intubation (SMI) is useful in surgical procedures where nasotracheal intubation is contraindicated and orotracheal intubation is not ideal, making it an alternative to tracheostomy since it is performed in less time, with less morbidity and mortality, minimal postoperatory care, as well as an aesthetically acceptable scar. We present 2 cases of pediatric patients with a successful SMI. In addition, we briefly review current literature regarding pediatric population.
Resumen La intubación submentoniana (ISM) es útil en procedimientos quirúrgicos en donde la intubación nasotraqueal está contra indicada y la intubación orotraqueal no es ideal, siendo así una alternativa a la traqueostomía, ya que se realiza en menor tiempo, con menor morbimortalidad y mínimos cuidados posoperatorios, y con una cicatriz estéticamente aceptable. Se presentan dos casos de pacientes pediátricos en los cuales la ISM fue exitosa y se revisa de forma breve la literatura relacionada en población infantil.

La evaluación de las biopsias cardiovasculares proporciona una visión panorámica actual sobre el avance de la cirugía y patología cardiovascular en nuestro país, especialmente en la Gran Caracas donde se concentran los mayores centros hospitalarios. Evaluar el material de patología quirúrgica cardiovascular y su relación con la situación médica y socioeconómica de nuestro medio. Se analizaron las biopsias cardiovasculares de los últimos 7 años (2001-2007) diagnosticados en la sección de patología cardiovascular del instituto Anatomopatológico (UCV). Se compararon con los 7 años anteriores (1994-2000). Se obtuvo las frecuencias del número total de las biopsias por año (2001-2007) y de los tipos de biopsias según su naturaleza. Se describió los protocolos del estudio anatomopatológico según el tipo de patología y los criterios de diagnóstico. Se demostró un aumento progresivo de las biopsias en los últimos 7 años (n =1550) vs. (n = 669). La distribución del material (2001-2007) según su naturaleza reveló: biopsias vasculares (51,0%), biopsias vasculares (35,0%), tumores cardíacos (5,0%) biopsia pericárdicas (4,0%) y las biopsias endomiocárdicas, congénitos y misceláneas (2,0% c/uno). Este trabajo proporcionó una visión panorámica de algunas enfermedades cardiovasculares quirúrgicas. Se comprobó un predominio de valvulopatías especialmente de las estenosis aórticas y valvulopatías reumáticas así como de los tumores cardíacos y un aumento importante de traumas vasculares por armas de fuego y blancas, así como descenso de las biopsias endomiocárdicas. Estas evidencias apuntan a algunos problemas de salud en relación con la situación socioeconómica de nuestro medio.
The evaluation of the material of cardiovascular biopsies provides a present panoramic vision on the advance of the surgery and cardiovascular pathology in our country, specially in the Great Caracas where the greater centers hospitals are concentrated in which this surgical subspecialty works. It is to evaluate the material of present cardiovascular surgical pathology and its relation with the medical and socioeconomic situation of our means. The annual information of the cardiovascular biopsies of last the 7 years (2001-2007) diagnosed in the Section of Cardiovascular Pathology of Institute of Pathology was analyzed (UCV). They were compared with the numbers of the 7 previous years. (1994-2000). One obtained the frequencies of the total number of the biopsies per year (2001-2007) and of the types of biopsies according to his nature. The protocols of the pathologic study of the material were described according to the type of pathology and the criteria talked about of the diagnostic. One in the last demonstrated to a progressive increase of the biopsies 7 years (n = 1550). The distribution of the material according to its nature revealed: valvular biopsies (51,0%), vascular biopsies (35,0%), cardiac' tumours (5,0%) Pericardial biopsies (4,0%) and the endomycardial biopsies, congenital and miscellaneous material (2,0% c/one). This work provided a panoramic vision of some surgical cardiovascular diseases. A predominance of valvulopathy of the aortic stenosis and rheumatic valvulopathy was verified especially as well as of cardiovascular tumours. A real reduction of the endomiocardicas biopsies was observed and an important increase of injuries you will tilt by gunshot wound and white. These evidences indicate to some problems of health in relation to our socioeconomic situation.

The distribution of intramembrane particles in human erythrocytes was studied by freeze-fracture on young and old cells and compared to that obtained after ATP depletion or following addition of a clustering agent. It was shown that intramembrane particles became aggregated and the mean particle density increased as the cells aged. Likewise, both particle aggregation and increased density were found in young cells after moderate ATP depletion. In contrast, mean particle density was markedly reduced in both cell types after exhaustive depletion. Paradoxically, Zn treatment led to decreased particle density in young cells, whilst producing the opposite effect in aged cells. The results suggest that their low ATP content may account for the increased particle density of senescent cells.
