OBJECTIVE: To outline the geographical distribution pattern of gestational trophoblastic disease (GTD) in a referral center in Bahia, Brazil, and determine the demographics of the disease.STUDY DESIGN: We conducted a study of data retrieved from medical records of 140 GTD patients referred to our Trophoblastic Diseases Center in 2002-2007, assessing geographical distribution across health care districts, demographics, referral sources, and previous pregnancy status.RESULTS: The most common GTD types were hydatidiform mole (106, 75.7%), invasive mole (32, 22.9%), choriocarcinoma (1, 0.7%), and placental site trophoblastic tumor (1, 0.7%). GTD incidence was 8.5 in 1,000 deliveries. Most patients originated from the coastal region (East district), which includes the state capital (77.9%). The 20-34 age group predominated (65%). Education level (67.9% attended elementary school only) and employment rate (42.9%) were low. Secondary hospitals were the principal source of referral (84.3%), followed by self-referrals (15.7%). Regarding previous pregnancy status, 42.1% (n = 59) had had term pregnancy, 39.3% (n = 55) no pregnancy, 15% (n = 21) miscarriage, and 0.7% (n = 1) ectopic pregnancy; 4 patients (2.9%) had previous hydatidiform mole.CONCLUSION: GTD predominated in the peak fertility age group and among patients of unfavorable sociodemographic status.

Brazilian spotted fever is caused by the bacterium Rickettsia rickettsii, which is the most pathogenic species of the spotted-fever rickettsiae group and is transmitted by the bite of infected ticks. Amblyomma cajennense is the most important tick species involved in the cycle of this zoonosis in Brazil as it presents low host specificity, great number of natural reservoirs and wide geographic distribution. It was first described in the state of São Paulo in 1929 and later in Rio de Janeiro, Minas Gerais and Bahia. The number of cases decreased in the 1940's with the development of new plague control techniques and antibiotics. In the last decades, the number of new cases has increased. The current review aimed at reporting some of the epidemiological and public health aspects of this reemergent disease with new foci, mainly in the southeastern region of Brazil.

Avaliou-se o fornecimento de concentrados com baixo e alto teor de óleo de soja a cavalos atletas, submetidos a duas intensidades de treinos aeróbicos montados, sobre a resposta metabólica de parâmetros bioquímicos do sangue, de importância ao desempenho esportivo. Foram utilizados quatro cavalos, em delineamento experimental quadrado latino, com tratamentos em esquema fatorial 2x2 (duas inclusões de óleo de soja e duas rotinas de treinos aeróbicos). Os tratamentos foram compostos por teores de 5 e 15% de óleo de soja nos concentrados e duas intensidades de treinos montados por 40 e 60min, classificadas como aeróbicas. As amostras de sangue foram colhidas após o último treino de 40 ou 60min, de cada período experimental. Monitorou-se, após o exercício, os parâmetros bioquímicos, triglicerídeos (TG), colesterol total (CT), glicose (GLI) e lactato (LAC). Houve redução no teor TG (P<0,05) para cavalos consumindo 15% de óleo e treinados aerobicamente por 60 min., o CT elevou-se em função do aumento da inclusão de óleo (P<0,05), incremento LAC (P<0,05) em cavalos treinados por 60min., independente do nível de óleo ingerido (1,48mmol/L), bem como não se verificou efeito (P>0,05) dos tratamentos sobre GLI. Concluiu-se que, para cavalos atletas em atividade aeróbica, o oferecimento de concentrado com alto teor óleo de soja deve ser associado ao treino montado de maior intensidade.

The objectives of this article are to provide a short history of dentistry and dental education in Brazil and to analyze the nature of its development to date. The databases consulted are those provided by the Brazilian Federal Council of Dentistry, Brazilian Ministry of Health, Brazilian Ministry of Education, National Institute of Studies and Educational Research Anisio Teixeira, and Brazilian Institute of Geography and Statistics. Formal dental education in Brazil started in the late nineteenth century with the creation of courses annexed to existing schools of medicine in Rio de Janeiro and Bahia. Today, there are 191 institutions of higher education nationwide granting degrees in dentistry (137 private [71.7 percent] and fifty-four public [28.3 percent]), with a total of 17,157 student positions offered annually. These schools graduate around 10,000 professionals per year-one of the highest rates in the world. Both the distribution of schools of dentistry and of dentists varies among the regions of the country, with the greatest concentrations in major metropolitan centers with high population density, resulting in limited coverage in the more deprived regions. A review of epidemiological data for oral health and distribution of dentists in Brazil indicates that there is a lack of systematic planning for the allocation of the dental workforce and a lack of consideration of regional needs in the development of dental training programs in Brazil today.

Aiming to study the affect of commercial biorregulators Stimulate (R) e X-Cyte (R) over sprouting uniformity of Superior Seedless grape cultivar, pruned in May 22, 2006, a field trial was carried out at at Koshiyama farm, in Juazeiro municipality (Bahia State / Northeastern Brazil). The trial was carried out in randomized blocks with four replications and three useful plants per plot, six stakes per plant were evaluated. Forty-eight hours after yield prun, the stakes were sprayed with T1: Dormex (R) (5%); T2: Dormex (R) (5%) + Nitro Plus 9 (R); T3: Stimulate (R) (0,5%); T4: Stimulate (R) (0,5%) + Nitro Plus 9 (R); T5: Stimulate (R) (1,0%); T6: Stimulate (R) (1,0%) + Nitro Plus 9 (R); T7: X-Cyte (R) (0,25%); T8: X-Cyte (R) (0,25%) + Nitro Plus 9 (R); T9: X-Cyte (R) (0,5%); T10: X-Cyte (R) (0,5%) + Nitro Plus 9 (R); T11: X-Cyte (R) (0,25%) + Stimulate (R) (0,5%); T12: X-Cyte (R) (0,25%) + Stimulate (R) (0,5%) + Nitro Plus 9 (R), Nitro Plus 9 (R) used at a rate of 100 L ha(-1) via ferti-irrigation. Results show that Stimulate (R) and X-Cyte (R), when compared to the commercial product Dormex (R) commercially, did not show significant effects on the sprouts number after sproutings and proportion of grown stems; products that as an alternative the Dormex (R) in yield the grape 'Superior Seedless', at the studied conditions.

The genus Actinocephalus comprises 25 species and is restricted to Brazil, occurring mainly in the Espinhaco Mountains of Minas Gerais and Bahia States. Previous anatomical studies have reported the occurrence of intracellular papillae in the Actinocephalus roots, without dealing with their ultrastructure and function. The purpose of this paper is to investigate the structure, the composition and the probable function of the intracellular papillae of Actinocephalus roots, based on light microscopy, transmission electron microscopy and histochemical tests. The intracellular papillae occurred in all root tissues, from the rhizodermis to the vascular cylinder; they presented different forms and sizes and, ultrastructurally, they corresponded to material deposited between the cell wall and the plasma membrane. The histochemical tests carried out were positive for cellulose, pectin and callose. The intracellular papillae are responses of the plant cells to the interaction with fungi. They work as a physical barrier restricting fungal penetration, and they may also favor the supply of water and nutrients to the plant, since they increase root absorption surface. This might explain why the species of Actinocephalus are among the tallest Eriocaulaceae despite their reduced radicular system and the nutritional deficiency of the soil in which they grow.

Recent field work in Atlantic Rain Forest patches in the southern region of the State of Bahia, Brazil, resulted in the discovery of some populations of an unidentified species of the Scinax catharinae group. An extensive literature review, along with the examination of specimens and distribution patterns of all known species of this group, showed that Hyla strigilata Spix, 1824, a long confused species with lost type material, is an available name for the specimens from Bahia. In order to clarify the taxonomic problems surrounding this taxon, the nomenclatural history of Hyla strigilata is reviewed and a neotype is designated, described, and figured. The association of this name to extant populations from southern Bahia and its consequent stabilization is considered important since it is the type species of the genus Ololygon, a name available for the clade of Scinax catharinae. Data on habits, habitat, and geographic distribution are also presented.

A pesca de arrasto é o método mais comum de captura de camarão. Esta técnica causa impactos negativos na fauna demersal devido ao grande número de animais que são capturados acidentalmente e que geralmente são devolvidos mortos ao mar. As conseqüências desta metodologia de pesca e os aspectos biológicos das espécies envolvidas são pouco estudados, especialmente no Nordeste do Brasil. Este estudo tem como objetivo mostrar aspectos biológicos de Isopisthus parvipinnis (tortinha) capturada como fauna acompanhante da pesca do camarão sete barbas (Xiphopenaeus kroyeri) na região de Ilhéus, no estado da Bahia, Brasil. Um total de 1290 indivíduos foram capturados em coletas mensais, em três pontos de coleta distintos, de março de 2003 a fevereiro de 2005. O índice de dispersão de Morisita padronizado sugere que a espécie, na área analisada, apresenta uma distribuição agregada. O número de indivíduos variou significativamente entre as estações do ano (p < 0,0001), sendo maior durante o inverno. O comprimento estimado de primeira maturação (L50) foi de 159 mm, sendo que 95% dos indivíduos capturados estavam abaixo deste valor. A razão sexual encontrada foi de 1,5 machos para cada fêmea. Quanto à dieta, foram identificadas 10 categorias alimentares, sendo que Decapoda Dendobranchiata foi a mais importante em freqüência numérica e de ocorrência. Este fato sugere que Isopisthus parvipinnis é uma espécie carnívora, com tendência a carcinofagia, ao menos nos indivíduos jovens.
