O presente trabalho relata um surto de intoxicação por sal em ovinos no Brasil, em uma propriedade no estado do Pará. De um total de 545 ovinos, oito animais adoeceram (1,46%) e quatro destes morreram (50%). A avaliação das instalações e do manejo indicaram como fatores predisponentes a ingestão excessiva de mistura mineral e a restrição hídrica. Os principais sinais clínicos foram decúbito, diminuição ou ausência da sensibilidade cutânea, ausência dos reflexos de ameaça, palpebral e auricular, midríase, nistagmo, opistótono, espasticidade de membros, sonolência e estupor. Havia ainda, timpanismo, diarreia, taquipneia, taquicardia, desidratação e poliúria. A evolução do quadro clínico nos animais que morreram variou de duas horas e meia a 48 horas. As médias das concentrações séricas de sódio e de potássio de 31 ovinos do mesmo lote afetado pela intoxicação, em amostras colhidas durante o surto, revelaram hipernatremia (190mEq/l) e hipercalemia (8,2mEq/l). À necropsia, observou-se em um animal, achatamento das circunvoluções cerebrais. Microscopicamente, neste animal, evidenciou-se vacuolização moderada do neurópilo, particularmente nas lâminas intermediárias do córtex cerebral, com aumento dos espaços perineural e perivascular. Nessas áreas foram observados ainda, acentuada tumefação e edema dos astrócitos e necrose neuronal aguda. A dosagem de sódio no encéfalo de um ovino, revelou-se elevada com valor de 3.513ppm. O diagnóstico foi realizado com base na epidemiologia, nos sinais clínicos, nas lesões macro e microscópicas e nas dosagens de sódio no soro e no encéfalo dos ovinos.

OBJECTIVE: To assess whether the Brazilian Driving Dry Law reached its goal after the three years following its enactment. METHODS: We onnducted a retrospective study of patients with craniofacial fractures who underwent surgery at a university hospital in two periods: before the Law (2005 to 2008) and after the Law (2008 to 2011). RESULTS: 265 patients (220 men and 45 women) were operated on during this period, 149 (56%) before and 116 (44%) after the Law, which indicates a reduction in the number of traumatisms (p=0.04). The age range between 19 and 40 years predominated in both periods. The main causes of traumas were car accidents, physical aggression and falls. Alcohol abuse was identified in 15.4% patients before and 19% patients after the enactment. The jaw and the maxillo-zygomatic complex were the most affected bones. CONCLUSION: The drop in the number of polytraumatized patients operated on at this institution in the three years following the Driving Dry Law was 22%, which is below the expected and desired percentage. These results must be compared to those of different services offering the same attendance type in order to compile data and enlarge statistics. The low index of reduction in the number of traumatisms and the report of alcohol abuse by several patients at the moment of trauma, even after the law, evidence the need of adopting stricter measures to control and punish violators.

This work presents an analysis of the pattern variation of the sky conditions in Botucatu/SP. The classification was based on the clarness index KT. It was used in the classification a database of global solar irradiance in the horizontal, measured at Radiometric Station of UNESP in Botucatu (latitude 22.85°S, longitude 48.43°W, altitude 786 m) from 1996 to 2005. We analyzed the variations in frequency, during the photoperiod and over the year, of the sky conditions: I - Cloudy (KT < 0.35); II - party cloudy with dominance for the diffuse (0.35 < 0.55 < KT)) III - party cloudy with dominance for the clear (0.55 < KT < 0.65) and IV - clear (KT > 0.65). The frequency of sky conditions I and II are higher during the rainy season of the year and in hours close to sunrise and sunset. And it is lower during the dry season an in hours near noon, in wich there is a predominance of sky conditions III and IV. The monthly hourly frequency of sky condition I ranged from 46,91% of the photoperiod in January to 25.27% in August. And the frequency monthly daily ranged from nine days in January to three days in August. To the sky condition IV, the frequency monthly hourly ranged from 38.81% of the photoperiod in August to 18.17% im January. And the frequency monthly daily ranged from 17 days in August to three days in January.
