Abstract: the polycystic ovary syndrome (pos) is a disorder of non well defined etiology with an aberrant hormonal pattern. the results of a descriptive cross-sectional study in which 30 women with clinical hyperandrogenism and at least 2 echographic elements suggestive of pos that were determined testosterone (t), androstenedione (ad), dihydroepiandrosterone (dhea) and its sulfate (dheas), follicle stimulating hormone (fsh) and luteinizing hormone (lh), were shown. descriptive statiscians and person's correlation test were used to analyze the results. the behavior of gonadotropins was very variable. the fsh was diminished in 3 cases, normal in 24 and increased in 3, with normal mean values (5.45 ui/l). the lh had values under the range of normality in 1 case, normal in 10 and high in 19, and an elevated mean value (12.49 ui/l). the ratio lh/fsh was over 3 in 14 patients (46.6 %). the mean values of all the androgens, excepting dheas were high; in 46.6 % of the cases it was found a rise of more than one androgen, and biochemical hyperandrogenism was not proved in 4 cases. the ad and the dhea were the most frequently rised androgens (50 % each one), followed by the t (30.0) and the dhea (10.0). no correlation was observed among the studied variables. it was concluded that the association of clinical hyperandrogenism and echographic signs of pos did not guarantee uniformity in the hormonal behavior, so it is necessary to continue working to determine the diagnostic element that identifies the syndrome really.

Abstract: El hipertiroidismo subclínico se define por la presencia de niveles disminuidos o no detectables de tirotropina, asociados a concentración de tetrayodotironina y triyodotironina libres dentro de parámetros normales. Su prevalencia en la población varía entre un 0,5 y un 16 % aproximadamente, y es el tratamiento con levotiroxina sódica la causa más frecuente. No siempre resulta tan asintomático, y las afectaciones principales ocurren sobre el sistema cardiovascular y óseo. Esta condición médica puede ser reversible espontáneamente. Por lo controversial del tema, el presente trabajo trata los aspectos clínicos más relevantes y la conducta a seguir. Subclinical hyperthyroidism is defined by presence of decreased o non-detected levels of thyrotropin, associated with free concentrations of tetraiodothyronine and triiodothyromime within normal parameters. Its prevalence in population differs between 0,5 % and 16 % approximately, and the sodium Levothyroxine treatment is the more frequent cause. Not always it is so asymptomatic, and main affections occur on cardiovascular and osseous system. This medical condition may be spontaneously reversible. Due to controversial of this topic, present paper approaching the more significant clinical features and the strategy to go on.

Abstract: ANTECEDENTES: la osteoporosis y diabetes mellitus constituyen problemas de salud para la población senescente en general y para la mujer en particular. El descontrol metabólico y las lesiones microvasculares de la DM afectan todo el organismo, incluyendo el hueso. OBJETIVO: determinar la calidad del hueso en mujeres de edad mediana con diabetes mellitus tipo 2. MéTODOS: estudio descriptivo-transversal, consistente en determinar la calidad del hueso en 30 mujeres con diabetes mellitus tipo 2, y 20 sin diabetes mellitus que constituyeron el grupo control. Se les realizó historia clínica, para precisar: edad, índice de masa corporal, circunferencia de cintura y actividad física; además, en las diabéticas: tiempo de evolución de la diabetes mellitus, glucemia en ayunas y posprandial de 2 h. La calidad del hueso se determinó mediante densitómetro LEXUS y se expresó como contenido mineral óseo y T-score en L2-L4 y el radio. Se utilizaron los criterios de la OMS para definir osteoporosis. Se emplearon estadígrafos descriptivos y correlaciones lineales. RESULTADOS: el 33 % de las pacientes con diabetes mellitus tipo 2 tuvo osteoporosis en el radio, y el 3,3 % en L2-L4, lo que ocurrió en el 75 y el 30 % respectivamente de las no diabéticas. El contenido mineral óseo en: L2-L4 de las diabéticas fue 0,561 g/cm2 yen el radiode 0,358 g/cm2, mientras en las no diabéticas fue 0,285 y 0,313 g/cm2 respectivamente (p<0,01 sig). El T-score de L2-L4 y el radio en ambos grupos fue mejor en las pacientes con actividad física adecuada. En las que tenían diabetes mellitus tipo 2 hubo asociación significativa positiva entre el índice de masa corporal > de 18,5 kg/m2 de superficie corporal (sc) y la circunferencia de cintura > de 88 cm con el contenido mineral óseo, y asociación negativa entre el T-score en el radio y la glucemia en ayunas 3 a 7mmol/L, y entre el tiempo de evolución > de 5 a os con el contenido mineral óseo en L2-L4 (p<0,05 sig). CONCLUSIONES: en nuestro estudio la calidad del hueso en las mujeres con diabetes mellitus tipo 2 fue mejor que en las que no tenían diabetes mellitus. BACKGROUND: osteoporosis and diabetes mellitus are health problems for the aging population in general and for females in particular.

Abstract: El síndrome de ovarios poliquísticos (SOP) es un trastorno de etiología no bien precisada con un patrón hormonal aberrante. Se muestran los resultados de un estudio descriptivo transversal en el que se incluyeron 30 mujeres con hiperandrogenismo clínico y al menos 2 elementos ecográficos sugestivos del SOP, a quienes se les determinó testosterona (T), androstenediona (Ad), dihidroepiandrosterona (DHEA) y su sulfato (DHEAs), hormona folículo estimulante (FSH) y hormona luteinizante (LH). Se emplearon estadígrafos descriptivos y prueba de correlación de Person para el análisis de los resultados. El comportamiento de las gonadotropinas fue muy variable: la FSH estuvo disminuida en 3 casos, normal en 24 y aumentada en 3, con valores medios normales (5,45 UI/L); la LH tuvo valores inferiores al rango de la normalidad en 1 caso, normales en 10 y elevados en 19, y un valor medio elevado (12,49 UI/L); la relación LH/FSH fue mayor de 3 en 14 pacientes (46,6 %). Los valores medios de todos los andrógenos, excepto la DHEAs, estuvieron elevados; en el 46,6 % de los casos se encontró elevación de más de 1 andrógeno y en 4 casos no se demostró hiperandrogenismo bioquímico; la Ad y la DHEA fueron los andrógenos más frecuentemente elevados (50 % cada una), seguidos de la T (30,0) y la DHEAs (10,0). No se demostró correlación entre ninguna de las variables estudiadas. Se concluye que la asociación de hiperandrogenismo clínico y signos ecográficos del SOP no garantiza uniformidad en el comportamiento hormonal, por lo que se debe continuar trabajando para determinar el elemento diagnóstico que verdaderamente identifique el síndrome.

Abstract: Los injertos de cartílago son ampliamente utilizados en Cirugía Plástica; sin embargo, existe un riesgo potencial de reabsorción que puede comprometer los logros obtenidos. Algunos autores presentan resultados exitosos utilizando injertos de cartílago envueltos en fascia. El propósito del trabajo es aportar evidencia científica en relación a las posibles ventajas de los mismos. Realizamos un estudio descriptivo, prospectivo, experimental y comparativo de 20 ratas blancas Sprague-Dawley, desde mayo a octubre del 2007. Las unidades de muestra fueron los cortes histológicos obtenidos del cartílagos tras ser implantados durante 8 semanas. Trabajamos con 2 grupos: grupo estudio, de 10 ratas con cartílago autológo envuelto en fascia y grupo control, de 10 ratas con cartílago sólo. Se realizó examen histológico e inmunohistoquímico determinando viabilidad, reacción inflamatoria, necrosis, reabsorción y capacidad de regeneración. Los injertos de cartílago autólogo envueltos en fascia resultaron menos fiables que los injertos de cartílago solos, mostrando una mayor reabsorción (80% frente a 60%), menor capacidad de regeneración (50% frente a 80%), mayor respuesta inflamatoria (80% frente a 30%), menor viabilidad (16% frente a 38%) y con necrosis (30%). El análisis estadístico no mostró diferencia significativa. En conclusión, la envoltura en fascia del injerto de cartílago autólogo no aumentó su viabilidad, ni disminuyó su reabsorción, en animales de experimentación.
