ABSTRACT. The study aimed to evaluate whether the addition of pequi increases the nutritional value of meatballs made with piranha and pacu fillets. Piranhas were obtained from the colony of fishermen; pacu with the fish farmer and the pequis were collected in nature. Fish were filleted and triturated, and the resulting masses were used to prepare 4 types of meatballs: piranha fillet with 2.0% pequi pulp, piranha fillet without pequi pulp, pacu fillet with with 2.0% pequi pulp, and pacu fillet without pequi pulp. After preparation, acceptance, purchase intention and frequency of consumption were evaluated with untrained tasters. Chemical composition parameters evaluated were crude protein, lipids, ash, moisture, carotenoids and antioxidant activity. Results of acceptability for all formulations were similar. The chemical composition of piranha meatballs presented differences (p < 0.05) for lipids and carotenoids. Pacu meatballs showed no difference (p > 0.05) for moisture, carotenoids, and antioxidant activity. The addition of pequi did not alter the organoleptic characteristics, however increased the nutritional values, therefore, it can add value to the product to be marketed and be more nutritionally attractive to the consumer.

OBJETIVO: Realizar o primeiro censo brasileiro de cirurgia refrativa. MÉTODOS: Entre agosto de 2001 e fevereiro de 2002 foram enviados questionários para 7.890 oftalmologistas brasileiros, com questões sobre aspectos demográficos, tendências, padrões de práticas, instrumentos, cuidados pré-operatórios e mercado da cirurgia refrativa. RESULTADOS: Novecentos e vinte questionários (11,67%) foram devidamente respondidos. O laser in situ ceratomileuse é a técnica preferida para correção de dioptrias entre +5,00 e -7,00 D. O excimer laser mais utilizado é o Nidek® EC 5000 e o microceratótomo mais freqüente é o Hansatome. Outros aspectos como: demográficos, procedimentos, técnicas, tendências, volume cirúrgico, cuidados pré-operatórios e mercado também foram analisados. CONCLUSÃO: A partir desta pesquisa, pode-se observar e monitorar aspectos demográficos, padrões de práticas, tendências, tecnologia e mercado da cirurgia refrativa no Brasil e compará-las com outras pesquisas semelhantes em outras partes do mundo.

PURPOSE: To perform the first Brazilian refractive surgery survey. METHODS: Between August 2001 and February 2002, a questionnaire was mailed to 7890 Brazilian ophthalmologists. The questionnaire presented questions about demographic aspects, technology, instruments, market, trends, practice patterns and cost of refractive surgery. RESULTS: Nine hundred and twenty questionnaires (11.67%) were answered. LASIK is the preferred technique for correction between +5.00 and -7.00 D. The mostly used excimer laser is Nidek® EC 5000, and Hansatome is the mostly used microkeratome. Others aspects like: demographic, techniques, practice patterns, trends, market, and pre-, intra- and postoperative care, were analyzed. CONCLUSION: With this survey, the Brazilian ophthalmologists can observe and monitor these aspects of refractive surgery in Brazil, and compare them with others surveys.

Objetivo: Avaliar o sucesso na redução da pressão intra-ocular, com a utilização de trabeculectomia simples e quando associada a 5-fluorouracil ou mitomicina-C e avaliar se o tempo de exposição à mitomicina-C modifica este índice de sucesso. Métodos: Analisaram-se retrospectivamente 171 olhos consecutivos, entre janeiro de 1989 e março de 1998, sendo 16 olhos submetidos à trabeculectomia simples, 38 olhos à trabeculectomia e aplicação pós-operatória de 5-fluorouracil e 117 olhos à trabeculectomia e aplicação intra-operatória de mitomicina-C. Resultados: Os resultados mostraram uma redução significativa da PIO (pressão intra-ocular), com o uso de antifibroblásticos (p < 0,05). O tempo de exposição à mitomicina-C não apresentou diferença estatisticamente significativa (p > 0,05). Conclusões: Os autores concluem que a trabeculectomia associada a drogas antifibroblásticas reduz a PIO de maneira significativa e promove estabilidade a curto prazo.

Purpose: To evaluate the success in reducing intraocular pressure (IOP) using trabeculectomy without antifibro-blastic drugs and trabeculectomy with adjunct 5-fluorou-racil or mitomycin-C as well as to assess if the time of mito-mycin-C exposure modifies this success rate. Methods: 171 consecutive eyes operated between January 1989 and March 1998 were retrospectively analyzed, 16 eyes having been submitted to simple trabeculectomy, 38 eyes to trabeculectomy and postoperative application of 5-fluorouracil and 117 eyes to trabeculectomy and intra-operative application of mitomycin-C. Results: There was a significant reduction in IOP with the use of antifibroblastic drugs (p<0.05). Exposure time to mitomycin-C did not present a statistically significant difference (p>0.05). Conclusions: Trabeculectomy associated with antifibro-blastic drugs significantly reduces IOP and promotes short-term stability.
