Central Vestibulopathy in a Female Collegiate Basketball Player: A Case

Abstract: We present a unique case of a collegiate athlete who suffered from a mild head injury following a multi-car motor vehicle accident and was later diagnosed with central vestibulopathy. A concussion is a mild head injury that involves a physiological disruption of brain function with at least one of four characteristics: (a) any period of loss of consciousness; (b) any retrograde or anterograde amnesia; (c) any immediate alteration of mental status; and (d) any neurological deficits (Kay et al., 1993). A history of brief unconsciousness is considered an indication for hospitalization because of the risk of delayed complications, such as a hematoma which is a collection of blood around the brain (Jennett, 1976). Approximately 90 % of new head injury cases each year are diagnosed as a concussion (Gottshall, Drake, Gray, McDonald, & Hoffer, 2003). While many concussions are diagnosed each year, certified athletic trainers and team physicians often have difficulty detecting and classifying concussions because of the varying signs and symptoms (Kelly & Torg, 1995). The most common signs and symptoms o

Successful renal vein reconstruction with bovine arterial heterografts.

Extensive damage to a short right renal vein complicated transplant surgery in two patients. The use of a segment of modified bovine arterial heterograft permitted successful transplantation in both cases. These results are in contrast to the reported inability of bovine arterial heterografts to remain patent elsewhere in the systemic venous system

Transplante isogênico de ilhotas de Langerhans no fígado de ratos: metodologia para separação e purificação das ilhotas de Langerhans Isogenic islet transplantation on the rat liver: Method for isolation and purification of the rat islets

A maior indicação do transplante de pâncreas ou de ilhotas de Langerhans é o diabetes mellitus do tipo I. O processo deve suprir as necessidades de insulina mantendo os níveis glicêmicos dentro da normalidade. Estudou-se o transplante isogênico de ilhotas de Langerhans no fígado de ratos WAG-RT1u. Com o método de separação e purificação das ilhotas de Langerhans obteve-se 2.834 ± 551,64 ilhotas com pureza de 83 ± 2,45%. O transplante de 2.834 ± 551,64 ilhotas de Langerhans no fígado destes animais, normalizou a glicemia que chegou a 35 mmol/L após indução do diabetes pela estreptozotocina, ficando em 9,62 ± 2,65 mmol/L nos primeiros 10 dias após o enxerto e 7,43 ± 0,27 mmol/L nos dias subseqüentes (P <0,05). O tempo médio de sobrevida das ilhotas transplantadas foi de 73 dias. Assim, o método para separação e purificação de ilhotas de Langerhans de ratos foi eficaz e o isotransplante de ilhotas de Langerhans em ratos foi efetivo na correção do diabetes induzido por estreptozotocina, havendo sobrevida média superior a 73 dias do enxerto e do animal quando os animais foram sacrificados.<br>The major indication for pancreas or islet transplantation is diabetes mellitus type I. This process has to supply the insulin necessity keeping glucose under control. We have studied isogenic islet transplantation on the rat (WAG-RT1u) liver. The method of isolation and purification of the islets obtained 2.834 ± 551,64 islets with purity of 83 ± 2,45%. Diabetes was induced by streptozotocin and seric glucose prior transplantation was 35 mmol/L. The islet transplantation of 2.834 ± 551,64 islets in the rat liver has normalized glucose test from 9,62 ± 2,65 mmol/L 10 days after transplantation to 7,43 ± 0,27 mmol/L later in the follow-up (P <0,05). The median survival time of the islets was 73 days. In conclusion both the method of isolation and purification of the islets and islet transplantation was effective in the control of the diabetes induced by streptozotocin with median survival time of both islet and rat more than 73 days when rats were sacrificied
