Situação vacinal de crianças atendidas em uma unidade de saúde na cidade de Porto Velho

Foi analisada a situação vacinal de 173 crianças de 0 a 2 anos de idade atendidas na Policlínica Hamilton Raulino Gondin situada num bairro periférico da cidade de Porto Velho, Rondônia. Os dados foram colhidos de maio a setembro de 2001 e obtidos através de entrevistas realizadas com o acompanhante da criança mediante a aplicação de formulário padronizado. Através deste instrumento foram analisadas as carteiras de vacina das crianças, tendo como critério o aprazamento das doses e colhidas informações referentes aos aspectos sócio-econômicos e culturais da família onde a criança está inserida. Os resultados mostraram que os maiores percentuais de atrasos encontrados foram 6,4% para a vacina contra a febre amarela e 5,8% para as vacinas contra sarampo (1ª e 2ª dose) e contra o Haemophilus influenza tipo b-Hib 3ª dose. Dentre os motivos de atrasos vacinais pesquisados o de maior relevância foi à falta de informação da mãe ou responsáveis. Estudando os fatores sócio-econômicos e culturais da família das crianças da amostra, evidenciou-se predominância de mães jovens, com idade entre 19 e 25 anos. Em relação ao grau de escolaridade do acompanhante das crianças, detectamos o percentual de 63,0% para o I grau incompleto. Analisando a renda das famílias das crianças do estudo observou-se que 29,5% vivem com rendimento compreendidos entre 1 e 2 salários mínimos.

BILL E. KUNKLE INTERDISCIPLINARY BEEF SYMPOSIUM: Temperament and acclimation to human handling influence growth, health, and reproductive responses in Bos taurus and Bos indicus cattle

Temperament in cattle is defined as the fear-related behavioral responses when exposed to human handling. Our group evaluates cattle temperament using 1) chute score on a 1 to 5 scale that increases according to excitable behavior during restraint in a squeeze chute, 2) exit velocity (speed of an animal exiting the squeeze chute), 3) exit score (dividing cattle according to exit velocity into quintiles using a 1 to 5 scale where 1 = cattle in the slowest quintile and 5 = cattle in the fastest quintile), and 4) temperament score (average of chute and exit scores). Subsequently, cattle are assigned a temperament type of adequate temperament (ADQ; temperament score <= 3) or excitable temperament (EXC; temperament score > 3). To assess the impacts of temperament on various beef production systems, our group associated these evaluation criteria with productive, reproductive, and health characteristics of Bos taurus and Bos indicus-influenced cattle. As expected, EXC cattle had greater plasma cortisol vs. ADQ cattle during handling, independent of breed type (B. indicus x B. taurus, P < 0.01; B. taurus, P < 0.01; B. indicus, P = 0.04) or age (cows, P < 0.01; heifers or steers, P < 0.01). In regards to reproduction, EXC females had reduced annual pregnancy rates vs. ADQ cohorts across breed types (B. taurus, P = 0.03; B. indicus, P = 0.05). Moreover, B. taurus EXC cows also had decreased calving rate (P = 0.04), weaning rate (P = 0.09), and kilograms of calf weaned/cow exposed to breeding (P = 0.08) vs. ADQ cohorts. In regards to feedlot cattle, B. indicus EXC steers had reduced ADG (P = 0.02) and G:F (P = 0.03) during a 109-d finishing period compared with ADQ cohorts. Bos taurus EXC cattle had reduced weaning BW (P = 0.04), greater acute-phase protein response on feedlot entry (P <= 0.05), impaired feedlot receiving ADG (P = 0.05), and reduced carcass weight (P = 0.07) vs. ADQ cohorts. Acclimating B. indicus x B. taurus or B. taurus heifers to human handling improved temperament (P <= 0.02), reduced plasma cortisol (P < 0.01), and hastened puberty attainment (P <= 0.02). However, no benefits were observed when mature cows or feeder cattle were acclimated to human handling. In conclusion, temperament impacts productive, reproductive, and health characteristics of beef cattle independent of breed type. Hence, strategies to improve herd temperament are imperative for optimal production efficiency of beef operations based on B. taurus and B. indicus-influenced cattle.

Frontonasal dysplasia: clinical evaluation on audiological and brainstem electrophysiological profiles

Frontonasal dysplasia (FND) is a rare malformative complex affecting the frontal portion of the face, the eyes and the nose; it may occur singly or associated with other clinical signs. No systematic studies describing hearing in this condition were found. AIM: To evaluate hearing sensitivity and sound stimulus conduction from cochlea to brainstem in patients with clinical signs of FND. METHODS: 21 patients with isolated or syndromic FND were submitted to a clinical (otological/vestibular antecedents and otoscopy) and instrumental (pure tone and speech audiometry, tympanometry and brainstem auditory evoked response) hearing evaluation. DESIGN: A clinical, cross-sectional observational prospective study. RESULTS: Hearing thresholds were normal in 15 (70%) patients, abnormal in 5 (25%), mostly with conductive hearing loss; one patient did not cooperate with testing. The tympanometric curve was type A in 30 (72%) ears, type C in 5 (12%), type As in 4 (9%) and type B in 3 (7%). The auditory brainstem response (ABR) showed no abnormalities. CONCLUSION: Patients with FND showed no abnormalities in the auditory system from cochlea to brainstem in this study. Mild conductive hearing loss found in some is probably related to cleft palate. Further evaluation of hearing pathways at higher levels is recommended.

Caracterização mineralógica, petrológica e química da sulfetação nos reef's da mina Canavieiras, Jacobina, Bahia

In the Serra de Jacobina, localized in the North Central portion of the state of Bahia, occours the Jacobina Group. It’s a sedimentary basin and the gold deposit is stocked on the basal portion, which consist on quartzites intercalated with oligomítico metaconglomerates of Serra do Córrego Formation. There are controversies about the origin of the gold mineralization, but the currently most accepted hypothesis corresponds to a paleoplacer deposit with subsequent ore remobilization and concentration by hydrothermal process. The sulphidation is one of the main results of hydrothermal process, which was more detail characterized, besides identifying if there was more than one sulfides phase generation and its relationship with gold mineralization. The analyzes were performed from the main reef's (metaconglomerates mineralized levels) of Mine Canavieiras: Maneira, Holandez, Liberino, Piritoso, MU and LU. Chemical analyzes semi-quantitative were developed with EDS in MEV and also petrographics analyses. The main sulfide is pyrite, followed by chalcopyrite. Six groups of pyrite were classified according with chemical composition, however they show similarities in their habit and occurrence. Were identified four types of chlorite, labeled A, B, C, D. Gold occurs in free form, associate to pyrites, to Fe-Ti-Muscovite, to chlorite type B and to microfractures with iron hydroxide. Gold presents three different compositions: pure, with Ag or associated with U-Zr. The results of chemical analysis showed that the hydrothermal process have as their main source, ultramafic rocks present in the Jacobina Basin

Tendência de crescimento facial em ortodontia e ortopedia funcional dos maxilares

The knowledge of the facial growth trend is very important in orthodontic treatment. A lateral headfilm is recommended in all young patients undergoing a preorthodontic guidance program to anticipate the best time to begin any mechanical procedures and the possibilities to determine the type of facial growth trend. In type A it will be observed that the middle and lower face are growing forward and downward in unison, with no change in ANB angle. Type B growth trends reveals that growth is downward and forward, with the middle face growing forward more rapidly than the lower and in type C the lower face is growing downward and forward more rapidly than the middle face revealing a decrease in the size of the ANB angle.
