Avaliou-se o emprego do adesivo de éster de cianoacrilato na síntese de feridas cutâneas de asininos, a partir da análise do tempo de duração do procedimento cirúrgico e do processo cicatricial. Para tanto, foram utilizados cinco asininos clinicamente sadios, machos, adultos, pesando 103±8,5 kg, nos quais foi realizada uma incisão cutânea de 10 cm, em sentido dorso-ventral, na região tóraco-lateral, caudal à escápula e ventral à cernelha, em ambos os lados. Realizou-se a aproximação dos tecidos adjacentes com categute simples 2-0 e a aproximação da pele, de um lado com fio de náilon (Grupo controle) e no lado oposto com o adesivo (Grupo Tratamento). Foram realizadas, diariamente, avaliações clínicas das feridas e por meio de microscopia de luz decorridos 10, 20 e 30 dias. A cola de cianoacrilato demonstrou ser uma alternativa viável para síntese cutânea de asininos, por ter reduzido o tempo de realização do procedimento cirúrgico em 35,3% e por permitir boa coaptação dos bordos da ferida, sem interferir com o processo cicatricial.

We evaluated the use of adhesive cyanoacrylate ester in the synthesis of skin wounds of donkeys by analyzing the duration of surgery and healing process. For this, we used five clinically healthy, male donkeys, weighing 103 ± 8.5 kg, in which we performed a 10 cm skin incision in the dorsal-ventral direction, in the thoraco-lateral region, ventral to the scapula and caudal to the withers on both sides. The adjacent tissue was brought together with 2-0 simple catgut and approximation of the skin on one side with nylon (Control Group) and on the opposite side with adhesive (treatment group). We assessed the wounds daily and clinically and by light microscopy after 10, 20 and 30 days. The cyanoacrylate glue proved to be a viable alternative for cutaneous synthesis of donkeys, for reducing the time of surgical procedure in 35.3%, and for allowing a good coaptation of the edges of the wound, without interfering with the healing process.

This study aimed to evaluate the occurrence of schistosomiasis in areas with low endemicity using polymerase chain reaction (PCR) as a diagnostic method. We analysed faecal samples from 219 individuals residing in Piau and Coronel Pacheco, state of Minas Gerais, Brazil, using a single faecal sample from each individual and two slides of the Kato-Katz technique as a gold standard. Fifteen out of the 219 samples were positive with both methods of diagnosis. One sample was diagnosed as positive by the Kato-Katz technique only and 61 were diagnosed only by PCR. The positivity rates were 7.3% with the Kato-Katz method and 34.7% with PCR. When both techniques were assumed to have 100% specificity and positive individuals were identified by both methods, the sensitivity of the Kato-Katz method was 20.8% and the PCR sensitivity was 98.7%. The Kappa index between the two techniques was 0.234, suggesting weak agreement. The assessment of a single faecal sample by PCR detected more cases of infection than the analysis of one sample with two slides using the Kato-Katz technique, suggesting that PCR can be a useful diagnostic tool, particularly in areas with low endemicity.
