    Castration and tail-docking of pre-wean piglets are common procedures that are known to induce pain and would benefit from pain mitigation. Flunixin meglumine (FM) is a non-steroidal anti-inflammatory drug currently approved in the United States for pyrexia in swine and lameness pain in cattle. The objective of this study was to establish the pharmacokinetic (PK) parameters resulting from intravenous (IV), intramuscular (IM), oral (PO) and transdermal (TD) administration of FM in pre-wean piglets. FM was administered to thirty-nine pre-wean piglets at a target dose of 2.2 mg/kg for IV and IM and 3.3 mg/kg for PO and TD route. Plasma was collected at twenty-seven time points from 0 to 9 days after FM administration and concentrations were determined using ultra-high performance liquid chromatography coupled with mass spectrometry (UPLC-MS). Pharmacokinetic data were analyzed using noncompartmental analysis (NCA) methods and nonlinear mixed-effects (NLME). Initial plasma concentration for IV (C0) 11,653 Ī¼g/L and mean peak plasma concentrations (Cmax) 6,543 Ī¼g/L (IM), 4,883 Ī¼g/L (PO), and 31.5 Ī¼g/L (TD) were measured. The time points of peak FM concentrations (tmax) were estimated 30 min, 1 h, and 24 h for IM, PO, and TD, respectively. The bioavailability (F) of PO and IM FM was estimated at >99%, while the bioavailability of TD FM was estimated to be 7.8%. The reported Cmax of FM after IM and PO administration is consistent with therapeutic concentration ranges that mitigate pain in other species and adult pigs. However, the low estimated concentration of FM after TD dosing is not expected to mitigate pain in pre-wean piglets. The low F of TD FM suggests that expanding the surface area of application is unlikely to be sufficient to establish an effective TD dose for pain, while the high bioavailability for PO FM should allow for an effective dose regimen to be established.This article is published as Kittrell, Heather C., Jonathan P.

    O estudo teve como objetivo avaliar as condiƧƵes do mobiliĆ”rio escolar disponibilizado aos alunos com paralisia cerebral nas escolas estaduais da cidade do Natal/RN em 2008 e a participaĆ§Ć£o do fisioterapeuta na prescriĆ§Ć£o deste mobiliĆ”rio. Os dados foram coletados atravĆ©s de um protocolo de avaliaĆ§Ć£o junto a cinco alunos com paralisia cerebral e formulĆ”rio aplicado aos diretores das instituiƧƵes de ensino, sendo analisados por meio das categorias suscitadas. Os resultados apontaram a presenƧa de mobiliĆ”rio escolar que nĆ£o atende as necessidades especĆ­ficas de posicionamento dos alunos avaliados e a ausĆŖncia do fisioterapeuta na prescriĆ§Ć£o desse mobiliĆ”rio. Constata-se a necessidade dos Ć³rgĆ£os gestores no Ć¢mbito da educaĆ§Ć£o de Natal/RN em cumprir o que determina a lei e disponibilizar mobiliĆ”rio escolar adequado aos alunos pesquisados. Assim, procurou-se garantir os recursos necessĆ”rios para promover um ensino de qualidade para os educandos com paralisia cerebral no contexto da escola regular.<br>The objective of this study was to evaluate the conditions of school furniture available for students with cerebral palsy in public schools in the city Natal, Rio Grande do Norte in 2008, looking at how physical therapists participated in the process of prescribing such furniture. The data was collected using an evaluation protocol with students with cerebral palsy and with school principals who filled out forms. The analysis was undertaken according to the categories that arose from the data. The results indicated that: 1) school furniture doesnā€™t meet the specific positioning needs of the students that were evaluated and 2) physical therapists do not participate in prescribing appropriate furniture. The study showed that in Natal, Rio Grande do Norte, educational administrators need to carry out the policies that have been determined by law in order to make proper school furniture available to students with cerebral palsy. The necessary resources must be ensured in order to guarantee optimum educational conditions for students with cerebral palsy in the regular school context
