Abstract: nowadays, the human immunodeficiency virus infection (hiv) is a cronic disease. in the frecuent clinical situations with fever, limph nodes and loss weight it is necessary to determine their etiology, for establishing a specific treatment. gastrointestinal opportunistic infections or gastric lymphomatous or sarcomatous process, which can accumulate ga67, may be present in the patient with acquired immunodeficiency syndrome. we report 2 cases with gastric uptake in which endoscopy and biopsy was obtained. in the first one, with previous treatment with omeprazol and almalgate for gastroesophagic reflux, endoscopy and biopsy were normal and in the second patient an helicobacter pylori infection was diagnosed. we think that gastric uptake of ga67 in hiv patients, must indicate to the clinician to rule out associated pathologies

Abstract: considering the clinical and surgical importance of lymphaticovenous communications, little described in cervical region, we presented and discussed the variations of these communications observed after the left supraclavicular fossa dissection of 34 adult cadavers used in the descriptive and topographic anatomy of the universidade federal de s?o paulo - escola paulista de medicina, brazil. we found two cases (5,9%) of lymphatic vessels that reach the left subclavian vein, near of the jugulosubclavian angle. in both cases, the thoracic duct was present and reach the usual local. anatomical studies of these variations are important due to it knowledge help to avoid consequences after chirurgical proceedings in the cervical region. besides, the findings of these studies contribute with more details on the lymphatic ways in this region

Abstract: La Administración de Tecnología de Información (ATI), pese a constituirse en una oportunidad profesional se encuentra desatendida curricularmente. Esta situación, ha conllevado a la escasa presencia de profesionales con dicho perfil, para hacer frente al arraigado y perjudicial fenómeno del Despilfarro Computacional. Para contribuir a subsanar lo anterior, el Grupo STI ha realizado esfuerzos investigativos alineados con estándares internacionales como CobiT , encaminados a desarrollar en los estudiantes y profesionales en Computación competencias en Consultoría en ATI. Así, se espera aportar a modificar la idea de la TI no como simple apoyo sino como función vital en las organizaciones.

Abstract: the arteries of the upper limb are variables principally due to modifications ocurred during the embryological development. the bifurcation of the braquial artery in their terminal branches, the ulnar and radial arteries, occurs at the elbow level but sometimes, it can be higher. in order to determine the level of bifurcation of this artery and their relationship with the median nerve, we made a morphometric study of these parameters in 72 upper limbs of 36 formolized adult brazilian cadavers from both sexes. the limbs were dissected and the morphometric data recorded with a digital caliper. we considered the biepicondylar line (bel) as a reference point. in the 87,5%of the cases, the braquial artery splits distal to this line and in 11,1%was proximal to it. when this bifurcation was distal, the average distance was 38.4 mm in the male and 30.0 mm in the female. the applied regression test to confirm a possible relation between this level of bifurcation and the forearm length was not significative. when the bifurcation was distal to the bel, the median nerve crossed ventral to the braquial artery in 54,9% of the cases and dorsal to it in 23,5% of them. the crossing point corresponded to 64,6 mm proximal to the bel

Abstract: Las arterias del miembro superior presentan variaciones debido fundamentalmente a modificaciones ocurridas durante el desarrollo embriológico. La bifurcación de la arteria braquial en arterias radial y ulnar ocurre a nível del codo pudiendo ésta ser más alta o más baja. Con el propósito de determinar el nivel de bifurcación de esta arteria y sus relaciones con el nervio mediano, realizamos un estudio morfométrico de estos parámetros en 72 miembros superiores de cadáveres formolizados, adultos, brasile os, de ambos sexos, utilizando para ello la disección y registrando los datos morfométricos con un paquímetro digital. Como punto de referencia se consideró a la línea biepicondilar (LBE). En el 87, 5 % de los casos, la arteria braquial se bifurcó distal a esta línea y en el 11,1 % fue proximal a la misma. La distancia promedio para la primera fue de 38,4 mm en el sexo masculino y de 30,00 mm en el femenino. El test de regresión linear aplicado para ver la posible relación entre este nivel y la longitud del brazo no fue estadistícamente significativo. Cuando la bifurcación fue distal a la LBE el nervio mediano cruzó ventralmente a la arteria braquial en 54,9 % de los casos y dorsalmente en 23,5 %. El punto de cruzamiento fue localizado a 64,6 mm de la línea biepicondilar The arteries of the upper limb are variables principally due to modifications ocurred during the embryological development.

Abstract: the musculocutaneous nerve is responsible for the motor innervation of the anterior arm muscles and sometimes it carryes by a short distance fibers of the median nerve. this fibers are part of a communicating branch between both, which may be ocurrent or not. with the object to detect their frequence of ocurrence and their localization level in the arm, 32 upper limbs from 16 formolized cadavers of brazilian individuals, from both sexes were dissected. the communicating branch was found in 10 cases (31.3 %), 9 of them on males with 4 cases in the right and 6 in the left side; in two individues it was bilateral. this investigation confirmed the macroscopical disposition of the communicating branch from the musculocutaneous nerve to the median nerve in 9 cases (90% of the total cases found) and at the contrary disposition in only one case. one of them was a double disposition. the branch was totally localized at the proximal third of the arm in two cases (20 %), inside the median third in 4 cases (40%) and between the proximal third an the median in the remaining 4 (40% of cases). the case with a contrary disposition was only found in the median third. the presence of this branch has an embriologic explanation and in cases of musculocutaneous nerve lessions can be to affected structures innervated by the median nerve

Abstract: due to increase of renal transplants and vascular reconstructions, the knowledge of variations of renal arteries is very important. the literature indicates that each kind have one artery, however sometimes there are origin and number variations. we describe in this article two cases with three arteries in the left side, found in the anatomy unit from health sciences faculty, universidad católica del maule, talca, chile. in one case, the origin of renal artery r1 (superior) from abdominal aorta, was to level of superior mesenteric artery origin. this r1 following a 30 mm trajectory divided in two minor branches of similar diameter and entered in the hilus passing in front of the renal vein. the origin of r2 (middle) was distal 4 mm to the r1, corresponding to a posterior branch that entered in the renal hilus and the r3 (inferior) originates distal 23 mm to the r2. this last artery entered in renal cortex, inferior to the renal sinus notch. in the second case, there were diferences with respect to the first case because r1 and r3 entered in the hilus, and, r2, with descendent course entered in renal cortex, similar to r3 of first case. the knowledge of these multiple arteries is necessary and should be kept in mind before and during surgery involving the renal region
