ABSTRACT

PURPOSE: Lung cancer is the leading cause of cancer death in Spain. The objective of our study was to evaluate the characteristics of patients diagnosed with stages I-III non-small-cell lung cancer, as well as the impact that epidemiological changes, diagnostic improvements and surgical therapeutic innovations have had on survival in the past 20 years. METHODS: Retrospective analysis of patients diagnosed with early and locally advanced non-small-cell lung cancer between years 2000 and 2017 in our institution. RESULTS: A total of 859 patients were included. An increase in the percentage of women diagnosed over time was observed. Statistically significant differences were observed in the mean age at diagnosis, with a progressive increase in the different periods. The percentage of current or former smokers was similar in all periods. Adenocarcinoma was the most frequent histologic type with a progressive increase in its frequency. The percentage of patients diagnosed in early stages has been increasing over the years. In stages I-II, there was a significant increase in the median survival (29.7 months: 2000-2004, 68.73 months: 2010-2014) that could be seen in stage III as well (14.7 months: 2000-2004, 30.63 months: 2015-2017). CONCLUSIONS: A variation of clinical characteristics of lung cancer in Spain has been observed in recent years, as well as an improvement in survival in early and locally advanced stages, due not only to the treatments, but also to a more accurate detection of these tumors. Little progress has been made in tobacco habit with high stable percentages over the years.

ABSTRACT

Los cordomas son tumores óseos primarios, poco frecuentes, derivados de remanentes no diferenciados de la notocorda. Por su origen histológico, suelen ubicarse en la línea media del esqueleto axial, y los lugares de presentación más frecuentes son la base del cráneo y la columna. Se caracterizan por presentar un crecimiento lento, por lo que tienden a ser clínicamente silenciosos hasta alcanzar tamaños que causan manifestaciones que varían según el sitio de presentación; sin embargo, tienen alta agresividad y recurrencia local. El tratamiento es quirúrgico e, idealmente, se busca una resección completa de la lesión. El artículo presenta el caso de un hombre de 20 años de edad, quien desarrolló un cordoma en la articulación facetaría superior izquierda de C4, que es una localización rara.


Chordoma are rare primar? bone tumours derived from non'difieren tiated remains of the notochord. Due to their histological origina, the most common site of presentation is on the mid'line of the axial skeleton, with a distribution that is most frequent on the sacral bone, skull base and mobile spine. These tumours have a slow growth rate, which means that symptoms occur when the size of the mass causes different manifestations according to its site of presentation. Howeveti they have aggressive behaviour with high rates of local recurrence. Ideal treatment is based on surgical block removal if possible. This article presents the case of a 20' year'old male patient with diagnosis of a chordoma on the leít superior facetar? articulation of C4.

ABSTRACT

BACKGROUND: We have shown that oligodeoxynucleotide IMT504 improved blood glucose and islet beta-cell content in streptozotocin (STZ)-induced diabetic rats, inducing early expression of progenitor markers. Here we determined the effect of IMT504 on islet infiltration and on immunomodulatory proteins indoleamine 2,3-dioxygenase (IDO) and TNF-α-stimulated gene/protein 6 (TSG-6) in islets of STZ-diabetic rats, at the time of progenitor markers expression. METHODS: Male rats were i.p. injected with STZ [60 mg/kg body weight (BW)] or citrate buffer (control) (day 1). Starting on day 4, STZ animals were daily treated with saline (STZ-saline) or IMT504 (20 mg/kg BW/day s.c., STZ-IMT504) and killed after two consecutive decreases in blood glucose. Islet area and insulin expression, CD3 (T lymphocytes), CD68 (macrophages), IDO and TSG-6 immunostainings were determined. Islet infiltration was also evaluated by haematoxylin staining. RESULTS: STZ-induced diabetes in rats, with an important decrease in islet area was reversed by IMT504. Diabetes development did not involve islet infiltration, determined by haematoxylin and by the absence of significant T lymphocyte and macrophage presence. IMT504 did not induce changes in these parameters. IDO was not expressed in controls; the percentages of IDO-positive islets were very low and similar in STZ-saline and STZ-IMT504. Scarce TSG-6 was expressed in all groups, without significant differences. CONCLUSIONS: IMT504 improved insulin content but did not alter IDO or TSG-6 staining in islets of STZ-diabetic rats, suggesting that they do not participate in the IMT504-induced repair process. IMT504 did not per se modify leukocyte presence in islets of diabetic rats.

ABSTRACT

Antecedentes: La infección urinaria es una de las causas más frecuentes de consulta en la población pediátrica. En la mayoría de los casos manejada empíricamente,siendo el Trimetoprim/sulfametoxazol el antibiótico más utilizado. El propósito de esta investigación es establecer la frecuencia de los diferentes agentes etiológicos causantes de infecciones del tracto urinario (ITU), su resistencia y sensibilidad a los antibióticos en población pediátrica. Materiales y métodos: Se realizó un análisis retrospectivo de 180 historias clínicas de niños menores de 14 años que ingresaron a una unidad de segundo nivel de atenciónen salud, del Valle de Aburrá. Resultados: Escherichia coli causó el 52.0% de las ITU, seguida del Enterococcus sp(26%). La resistencia al Trimetoprim/Sulfametoxazol fue del 80%, seguida por Ampicilina(71.4%) y Ciprofloxacina (61.5%). Los antibióticos con mejor respuesta fueron laAmikacina (94.4%) y la nitrofurantoína (93.3%). Se estableció que existe una relaciónsignificativa (p=0.003; OR= 2.53) entre urocultivo positivo para E. coli y pacientes confiebre; el 6.11% de la población presentó malformación del tracto genitourinario. Conclusiones: Escherichia coli fue el agente más frecuente en infección del tractourinario, presentando alta resistencia al Trimetoprim/Sulfametoxazol. La malformación más frecuente fue el reflujo vesicoureteral principalmente en menores de dos años; además se mostró la importancia de conocer los datos epidemiológicos locales y el comportamiento de estas bacterias, para un adecuado manejo y seguimiento de niños con infección del tracto urinario...

ABSTRACT

Desde una perspectiva psicosocial que ahonda en la dimensión subjetiva de la cultura se indaga en creencias y valores asociadas al trabajo. A partir de investigaciones previas y los presupuestos de la teoría de los valores, la centralidad del trabajo y la ética protestante del trabajo, se ha realizado un estudio empírico de naturaleza exploratoria descriptiva. El objetivo general de la investigación marco es explorar en diferentes muestras urbanas aspectos psicosociales relacionados con el trabajo. En este estudio se analiza la información obtenida de una muestra no probabilística intencional compuesta por 226 sujetos activos laboralmente de la ciudad de Buenos Aires y el Conurbano Bonaerense que respondieron a un cuestionario auto-administrado. Los resultados muestran una alta centralidad absoluta y relativa del trabajo, la presencia de valores de autotrascendencia y apertura al cambio y puntuaciones altas en lo que refiere a Ética Protestante del Trabajo y Competitividad.

ABSTRACT

Eleven male chronic alcoholics without cirrhosis but with clinical features of alcoholism were studied. Ten healthy men of similar age served as controls. After suppressing hormone (FSH), luteinizing hormone (LH), 17-beta-oestradiol (E2) and testosterone were determined in basal conditions and after administration of clomiphene citrate in each case. Basal levels of FSH, LH and E2 were higher and the testosterone level lower in the alcoholic group. After stimulation, there was no difference in gonadal hormone levels between both groups, suggesting a normal hypothalamic-pituitary axis with an adequate gonadal response.
