Examinou-se a mortalidade por neoplasias no Brasil, utilizando-se dados oficiais do Ministério da Saúde, abrangendo 26 Unidades da Federação e 13 diferentes localizações neoplásicas, para os anos de 1980, 1983 e 1985. As Análises de Agrupamento e de Componentes Principais revelaram comportamento heterogêneo entre regiões do país, com relação às 13 variáveis estudadas, sendo que os principais elementos discriminantes foram as neoplasias malignas da traquéia/brônquio/pulmão, seguidas das do estômago, esôfago, cólon e pâncreas. Análises complementares evidenciaram tendência de crescimento das taxas de mortalidade para as neoplasias malignas da próstata (17,74%), da traquéia/brônquio/pulmão(15,22%), da mama (11,32%), do pâncreas (10,23%), do cólon (8,08%), do colo uterino (6,45%) e da laringe (6,36%). Houve redução da mortalidade por neoplasias benignas/carcinoma in situ/ outras (27,37%), por neoplasias malignas no reto sigmóide/ânus (7,67%), do estômago (5,31%), de outro local do útero não especificado (2,56%), por leucemia (0,70%) e por neoplasias malignas do esôfago (0,44%). As neoplasias malignas do estômago foram a principal causa de morte por câncer no Brasil, representando 21,30% do total médio, seguidas das neoplasias malignas da traquéia/brônquio/pulmão(17,49% do total médio). Destacam-se os altos índices de mortalidade por neoplasias malignas do esôfago no Estado do Rio Grande do Sul.

Hyperprolactinemia is the most frequent endocrine disorder of the hypothalamus-hypophysis axis observed in women of reproductive age. It is characterized by elevated serum prolactin levels. Prolactin production is regulated by the inhibitory action of a neurotransmitter, dopamine. Clinical manifestations include irregular menstrual cycle, amenorrhea, galactorrhea, infertility and libido decrease, but psychological symptoms, especially anxiety and depression, have also been associated with hyperprolactinemia. Nonetheless, few studies about this condition are available. In the pathogenesis of psychiatric disorders, prolactin may have either a direct action on the central nerve system or an indirect effect via gonadal hormones or function as independent factors as a result of dopamine depletion. Thus, since the prevalence of psychiatric disorders in patients with hyperprolactinemia was detected, it was concluded that further studies are necessary to investigate the basis of a potential relationship between both hyperprolactinemic and psychiatric conditions.

The basalts of the Formação Serra Geral in Parana Basin in the Mato Grosso do Sul and Mato Grosso states cover an area of 180,000 km2. They rest on the Botucatu sandstones and they are recovered by the sedimentary rocks of Bauru and Caiuá Groups. The mineralogical composition of these rocks are plagioclase (40%-55%), clinopyroxenes (19%-40%; augite and pigeonite), opaque minerals (2%-10%; magnetite and ilmenite) and olivine (1.5%). Geochemical data show two different types of basalts, named ATi-Pitanga (2.6% < TiO2 < 4.2%; 396 ppm < Sr < 438 ppm) and BTi-Ribeira (1.7% TiO2 <2.4%, 246 ppm < Sr < 286 ppm). In general, ATi-Pitanga have gently higher La/Yb(n) (6,1 ± 1,5ppm) than those BTi-Ribeira (5.6 ± 1,7ppm). The geochemical differences between ATi-Pitanga and BTi-Ribeira probably are related to different degrees of partial melt of a same mantle source, or to different mantle sources. The field relations show that BTi-Ribeira is displaced towards the north-western margin of the Paraná Basin and the thickness of lava flows increases towards the Paraná Graben, suggesting that ATi-Pitaga overlies BTi-Ribeira.
