Tiroiditis de Quervain. Informe de caso / De Queravin’s thyroiditis. Inform of a case

La tiroiditis de Quervain es probablemente de origen viral. Los síntomas suelen aparecer después de una infección de las vías respiratorias altas, y se caracterizan por malestar general, febrícula y dolor, generalmente unilateral, sobre el tiroides o referido hacia los oídos o la mandíbula. En la exploración se destaca una gran sensibilidad a la palpación del tiroides, que se encuentra aumentado de tamaño y nodular. En algunas ocasiones no aparece dolor, siendo raro que debute con signos de hipertiroidismo grave. Lo característico es el aumento de la velocidad de sedimentación y la disminución de la captación tiroidea de yodo radiactivo. Respecto a los niveles hormonales, en una primera etapa, T4, T3 están elevadas y TSH suprimida; posteriormente, a medida que se vacía la glándula de hormona se produce una fase de hipotiroidismo. El diagnóstico diferencial debe establecerse con la enfermedad de graves y con la tiroiditis silente, entre otras. El proceso evoluciona a lo largo de varios meses produciéndose recuperación completa de la función tiroidea. En aquellos casos más leves, los síntomas se suelen controlar con antiinflamatorios, siendo necesaria la utilización de esteroides en los casos que presentan más gravedad. No está indicado el tratamiento con antitiroideos y se puede utilizar el propanolol para controlar los síntomas de hipertiroidismo. Al tener un paciente con estas características decidimos presentarlo.

This entity probably has a viral origin. The symptoms usually began after an infection of the upper respiratory ways and are characterized by general discomfort, mild fever and pain, generally unilateral, on the thyroid or referred to ears and jawbone. In the exploration, there is a great sensibility at the touch of the thyroid, nodular and increased in size. Sometimes there is no pain, being rare the debut with signs of serious hyperthyroidism. What it is characteristic is the increase of the sedimentation speed and the decrease of the thyroidal capture of radioactive iodine. Respecting the hormonal levels, in the first stage T4 and T3 are increased and TSH eliminated; lately, as the hormonal gland gets empty, there is a stage of hypothyroidism. The differential diagnosis should be established with the serious disease and with the silent thyroiditis. The process evolves during several months achieving the complete recovering of the thyroidal function. In those milder cases, it is usual to control the symptoms with anti inflammatory drugs, being necessary the use of the steroidal ones in most in the most serious cases. It is not indicated the treatment with anti thyroids and propranolol may be used to control the symptoms of hyperthyroidism. Having a patient with these characteristics we decided to present the case.

Transformación leucémica del clon Marchiafava Micheli. Informe de caso / Leukemic transformation of the Marchiafava Micheli clone. Inform of a case

La hemoglobinuria paroxística nocturna, también conocida como síndrome de Marchiafava-Micheli, es una enfermedad clonal y adquirida, causada por una mutación somática en el gen PIG-A que se encuentra en el cromosoma X y codifica una proteína involucrada en la síntesis del glicosilfosfatidilinositol, el cual le sirve como anclaje a muchas proteínas de la membrana celular; es la única anemia hemolítica adquirida por defecto de la membrana del eritrocito. Se caracteriza por una anemia hemolítica crónica intravascular, hemoglobinuria, hipercoagulabilidad, citopenia debido al fallo de la médula ósea, trombosis y raramente transformación leucémica. Al tener un paciente con estas características se decidió presentarlo.

The nocturnal paroxysmal hemoglobinuria, also known as Marchiafava-Micheli syndrome, is a clonal and acquired disease, caused by a somatic mutation of the PIG-A gene located in the X chromosome and modified a protein involved in the glicosilfosfatidilinositol synthesis that serves as anchorage for many proteins of the cell membrane; it is the only hemolytic anemia acquired by defect of the erythrocyte membrane. It is characterized by a chronic intravascular hemolytic anemia, hemoglobinuria, hyper coagulation, cytopenia due to the marrow failure, thrombosis and rarely leukemic transformation. Having a patient with these characteristics we decided to present the case.

14, 15-epoxygeranylgeraniol and extracts isolated from Pterodon emarginatus Vog. fruits: antitumor activity on glioblastoma cells.

Plant-derived substances have traditionally played important roles in the treatment of human diseases, including of great significance to cancer therapy. Plants of the genus Pterodon (Fabaceae, Leguminosae), commonly known as ‘sucupira’, are disseminated throughout the central region of Brazil and have been used frequently in popular medicine. In recent years, interest in these plants has increased considerably. The biological effects of their extracts and pure metabolites have been investigated in several experimental models in vivo and in vitro. Until the present day, the antitumor effect of Pterodon plants on brain tumors is unknown. Therefore, the aim of this work was to investigate the action of P. emarginatus Vogel extracts and its fractions on glioblastoma cells. The hexane (HE), dichloromethane (DE) and ethanol (EE) extracts were obtained from seeds powder in each solvent. The diterpene 14,15-epoxygeranylgeraniol was obtained from HE fractionation. For tumorigenic assays, the extracts and fractions were added to U87MG, a human glioblastoma cells line. The cell viability assay showed that the proliferation of U87MG was inhibited by both extracts and the 14,15- epoxygeranylgeraniol. Further trials in vivo will help to confirm these results, and may contribute to generate natural compounds for the treatment of this type of cancer.

Pharmaceutical properties of 'sucupira' (Pterodon spp. ) / Propriedades farmacêuticas de "sucupira" (Pterodon spp. )

The plant of the genus Pterodon (Fabaceae, Leguminosae), commonly known as 'sucupira' or 'faveira', are disseminated throughout the central region of Brazil and has frequently been used in popular medicine for its anti-rheumatic, analgesic, and anti-inflammatory properties. In recent years, interest in these plants has increased considerably. The biological effects of different phytoextracts and pure metabolites have been investigated in several experimental models in vivo and in vitro. The literature describes flavonoids, triterpene and steroids, while one paper presented studies with proteins isolated from the genus. This review provides an overview of phytochemical and pharmacological research in Pterodon, showing the main chemical compounds studied to date, and focusing on the relationship between these molecules and their biological activity. Furthermore, this study paves the way for more in-depth investigation, isolation and characterization of the molecules of this plant genus.

As plantas do gênero Pterodon (Fabaceae/Leguminosae), conhecidas popularmente como "sucupira branca" ou "faveira", encontram-se distribuídas pela região central do Brasil e são frequentemente utilizadas na medicina popular por suas propriedades antirreumáticas, analgésicas e antiinflamatórias. Nos últimos anos, o interesse por estas plantas tem aumentado consideravelmente. Os efeitos biológicos dos diferentes fitoextratos e metabólitos puros têm sido investigados em vários modelos experimentais in vivo e in vitro.
