    Resultados de histologia renal são muito escassos em pacientes com rabdomiólise e injúria renal aguda (IRA) associada a dengue. Descrevemos caso de dengue complicado por rabdomiólise e IRA no qual a biópsia renal mostrou necrose tubular aguda (NTA) e deposição renal de mioglobina. Paciente de 28 anos que apresentou dengue complicado por IRA grave e rabdomiólise é descrito. Ele necessitou de diálise por três semanas. A biópsia renal mostrou NTA, com imunohistoquímica fortemente positiva para mioglobina nos túbulos renais. O paciente recebeu alta com recuperação da função renal. Em conclusão, descrevemos caso de dengue complicado por IRA e rabdomiólise, em que a biópsia renal mostrou NTA e deposição de mioglobina. Sugerimos que creatinofosfoquinase deve ser monitorizada em pacientes com dengue para permitir o diagnóstico precoce de rabdomiólise e a instituição de medidas protetoras para o rim.Renal histology results are very scarce in dengue-associated rhabdomyolysis patients developing acute kidney injury (AKI). We report a case of dengue fever-induced AKI associated to rhabdomyolysis with a renal biopsy showing acute tubular necrosis (ATN) and renal deposition of myoglobin. A 28-year-old patient who presented dengue fever (DF) complicated by severe AKI and rhabdomyolysis is described. The patient required hemodialysis for three weeks. A renal biopsy revealed ATN with positive staining for myoglobin in the renal tubuli. The patient was discharged with recovered renal function. In conclusion, this case report described a biopsy proven ATN associated to DF-induced rhabdomyolysis, in which renal deposition of myoglobin was demonstrated. We suggest that serum creatine phosphokinase should be monitored in DF patients to allow for an early diagnosis of rhabdomyolysis and the institution of renal protective measures

    Eletrorretinograma (ERG) é o meio diagnóstico objetivo e não-invasivo para avaliar a função retiniana e detectar precocemente, em várias espécies, lesões nas suas camadas mais externas. As indicações mais comuns para ERG em cães são: avaliação pré-cirúrgica de pacientes com catarata, caracterização de distúrbios que causam cegueira, além de servir como importante modelo para o estudo da distrofia retiniana que acomete o homem. Vários são os fatores que podem alterar o ERG tais como: eletrorretinógrafo, fonte de estimulação luminosa, tipo do eletrodo, tempo de adaptação ao escuro, tamanho pupilar, opacidade de meios e protocolo de sedação ou anestesia; além da espécie, raça e idade. Objetivou-se com este estudo padronizar o ERG para cães submetidos à sedação, seguindo o protocolo da International Society for Clinical Electrophysiology of Vision (ISCEV), utilizando Ganzfeld e eletrodos Burian Allen. Foram realizados 233 eletrorretinogramas em cães, 147 fêmeas e 86 machos, com idades entre um e 14 anos. Dos 233 cães examinados, 100 apresentavam catarata em diferentes estágios de maturação, 72 eram diabéticos e apresentavam catarata madura ou hipermadura, 26 apresentaram eletrorretinograma compatível com degeneração retiniana progressiva, três apresentaram eletrorretinograma compatível com síndrome da degeneração retiniana adquirida subitamente e 32 não apresentaram lesão retiniana capaz de atenuar as respostas do ERG, sendo considerados normais quanto à função retiniana. A sedação foi capaz de produzir boa imobilização do paciente sem rotacionar o bulbo ocular, permitindo adequada estimulação retiniana bilateralmente, com auxílio do Ganzfeld. O sistema eletrodiagnóstico Veris registrou com sucesso e simultaneamente de ambos os olhos, as cinco respostas preconizadas pela ISCEV. Como o ERG de campo total tornou-se exame fundamental na rotina oftalmológica, sua padronização é indispensável quando se objetiva comparar resultados de laboratórios distintos. A confiabilidade e reprodutibilidade deste protocolo foi demonstrada com a obtenção de registros de ótima qualidade utilizando protocolo padrão da ISCEV, eletrorretinógrafo Veris, Ganzfeld e eletrodos Burian Allen nos cães submetidos à sedação.Electroretinogram (ERG) is an objective non invasive diagnostic method to evaluate retinal function which permits the early detection of lesions at retinal external layers, even before the appearance of clinical signs. In dogs, ERG is mostly utilized for preoperative evaluation in patients presenting cataracts; characterization of disturbances causing blindness, among the utilization of dogs as animal models in scientific research. Several factors interfere in ERG responses, such as the ERG machine, light stimulation, electrode, time spent on dark adaptation, pupil size, means opacity, sedation or anesthetization, species, breed and age. The purpose of this study was to standardize the full field ERG in sedated dogs, according to the International Society for Clinical Electrophysiology of Vision (ISCEV) protocol, using Ganzfeld and bipolar electrodes. Two hundred thirty threes ERGs were performed in 147 female and 86 male with ages from 1 to 14 years old. Among those 233 dogs, 100 presented cataracts in different stages of maturation, 72 were diabetic and presented mature or hypermature cataracts, 26 presented ERG compatible to progressive retinal degeneration, 3 presented ERG compatible to sudden acquired retinal degeneration syndrome; for 32 dogs no abnormal ERG was registered and they were considered as having normal retinal function. Sedation was capable to induce a good immobilization with no bulb rotation, resulting uniform retinal stimulation, using Ganzfeld. Veris system successfully registered all 5 ISCEV responses, simultaneously from both eyes, at the same time. Full field ERG became a fundamental ophthalmic exam, then, its standardization is mandatory to allow comparison between ERGs from different laboratories. The reliability and reproducibility of this protocol has shown very good responses, using ISCEV protocol, Veris system, Ganzfeld and Burian Allen electrodes in sedated dogs.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

    COPIGMENTAÇÃO INTRA E INTERMOLECULAR DE ANTOCIANINAS: UMA REVISÃO

    Get PDF
    Este trabalho apresenta revisão de literatura sobre a reação de copigmentação intra e intermolecular e sua relevância na estabilização de antocianinas. Flavonóides não-antociânicos, alcalóides, aminoácidos e nucleosídios, entre outros, podem atuar como copigmentos de antocianinas. O aumento na estabilidade das antocianinas ocorre devido à proteção fornecida pelo copigmento frente à reação de hidratação do cátion flavilium. Estudos ainda são necessários para avaliar a estabilidade de antocianinas adicionadas de copigmentos em sistemas modelos de alimentos, visando aumentar o espectro de aplicação dessas como corantes em alimentos e bebidas. ANTHOCYANINS INTRA AND INTERMOLECULAR COPIGMENTATION: A REVIEW Abstract This research presents literature review about the reaction of intra and intermolecular copigmentation and its revealance in anthocyanins stabilization. Non-anthocyanic flavonoids, alkaloids, amino acids, nucleosides, and others, can act as anthocyanins copigments. The increase in the stability of anthocyanins occurs due to protection supplied by the copigment towards the hydratation reaction of colored flavylium cation. Studies to evaluate anthocyanins stabilization added of copigments in food models system are still necessary, aiming to enhance the application spectra as colorants in foods and beverages
