Pleuroperitoneal hernias are the most uncommon type of diaphragmatic hernias in dogs and cats. The treatment of choice is surgery and may involve the use of prosthetic implant through celiotomy. In the current report, laparoscopic repair of a congenital pleuroperitoneal hernia using polypropylene mesh in a dog is described. The surgery was feasible. Appropriate reduction of the hernia was carried out and no complications were noted.

Mesothelioma is a very aggressive malignant tumor with low survival rates that is often diagnosed belatedly. Pericardial effusion is a common consequence in cases of mesothelioma, with pericardiocentesis and pericardiectomy indicated; therefor thoracocentesis is necessary to drain the contents no longer retained in the pericardium. The present report describes a mesothelioma–carrying dog with a history of cardiac tamponade that underwent thoracoscopic pericardiectomy and, later, thoracoscopic implantation of a fully implantable catheter to function as a thoracic drain. In the consulted literature, there is no use of a fully implantable catheter for this purpose. The authors consider that there was an improvement in the quality of life.

Introduction: Nanoparticle solutions have been studied to improve antimicrobial effect. The aim of this study was to develop, characterize, and evaluate the in vitro and in vivo antiseptic efficacy of 0.25% aqueous-based chlorhexidine nanoemulsion (NM-Cl 0.25% w/v). Methods: The NM-Cl 0.25% w/v (2.5mg/mL) and free chlorhexidine nanoemulsion (FCN; same composition of NM-Cl without the molecule of chlorhexidine) were synthetized by the spontaneous emulsification method. Characterization analyses of physical and chemical properties were performed. The NM-Cl 0.25% w/v was compared with chlorhexidine 0.5% alcohol base (CS-Cl 0.5%) in vitro studies (microdilution study and kill curve study), and in vivo study (antisepsis of rats dorsum). Kruskal-Wallis test was used between groups and inside the same group, at different sample times and the Mann-Whitney test was performed when difference was detected. Results: The NM-Cl 0.25% w/v presented adequate physicochemical characteristics for a nanoemulsion, revealing a more basic pH than FCN and difference between zeta potential of NM-Cl 0.25% w/v and FCN. The NM-Cl 0.25% w/v and CS-Cl 0.5% solutions were more effective on Gram-positive than on Gram-negative bacteria (p≤0.05). NM-Cl 0.25% w/v presented upper antiseptic effect in the microdilution study and residual antiseptic effect was maintained for a longer time when compared to CS-Cl 0.5% (kill curve study). The four-fold (minimal inhibitory concentration) of NM-Cl 0.25% were the formulations with most durable effect within those tested, presenting residual effect until T6 for both bacteria. In the in vivo study, both formulations (NM-Cl 0.25% w/v and CS-Cl 0.5%) had a reduction of the microorganisms in the skin of the rats (p<0.0001) not revealing any difference between the formulations at different times, showing the antiseptic effect of NM-Cl (p≤0.05). Conclusion: Both in vitro and in vivo experiments demonstrated that NM-Cl showed promising future as an antiseptic for cutaneous microbiota.

A 2-year-old female mixed-breed cat weighing 2.7 kg presented with recurrent rectal prolapse. The following report describes its treatment by laparoscopic-assisted incisional colopexy using two portals. The procedure was effective and without trans- or postoperative complications. Recurrent prolapses did not recur in the 2 months of postoperative observation.

RESUMOA intussuscepção uterina é condição rara em pequenos animais. No presente relato descreve-se um caso de intussuscepção uterina em um canino, fêmea Yorkshire Terrier no pós-parto imediato, diagnosticada por meio de laparotomia exploratória e pela avaliação anatomopatológica. Realizou-se a ovariossalpingohisterectomia (OSH) como tratamento definitivo para a alteração. Conclui-se, portanto, que a intussuscepção uterina pode ocorrer em cadelas, de forma espontânea no pós-parto imediato.Palavras-chave: cão, cirurgia, inversão uterina, parto ABSTRACT Uterine intussusception has rarely been described in small animals. In this report we describe a case of uterine intussusception in a female Yorkshire terrier immediately postpartum, diagnosed by exploratory laparotomy and anatomopathologic evaluation. Ovariosalpingohisterectomy (OSH) was performed as definitive treatment. It is concluded that the intussusception of the uterus may occur spontaneously in dogs immediately postpartum.Keywords: dog, surgery, uterine inversion, parturition INTRODUÇÃO  O útero é o órgão reprodutivo muscular que serve como local de inserção para óvulos fertilizados e que proporciona fonte de nutrição fetal, sendo formado pela cérvix, um corpo e dois cornos (Wykes e Olson, 1996). O corpo uterino tem cerca de 1,5cm de comprimento e 1cm de largura nas cadelas, enquanto nas gatas pode ter 2cm de comprimento. Está localizado parcialmente na cavidade pélvica, mas em fêmeas pluríparas pode se posicionar totalmente dentro da cavidade abdominal. O corpo uterino situa-se entre o cólon descendente e a bexiga. Uma projeção interna musculomembranosa, não visível externamente, estende-se 1cm para dentro deste, dividindo o lúmen uterino longitudinalmente. Nas cadelas, a cérvix possui Recebido em 28 de fevereiro de 2013 Aceito em 16 de dezembro de 2013 *Autor para correspondência (corresponding author) E-mail: mauriciovelosobrun@hotmail.com cerca de 1cm de comprimento (Stone, 2007). O tubérculo cervical situa-se na extremidade cranial da prega média dorsal e está separado por uma prega transversal evidente (Wilson, 2003). O orifício interno da cérvix está voltado quase que dorsalmente, e o orifício externo está direcionado ventralmente, na direção do assoalho vaginal (Wilson, 2003;Stone, 2007).As anomalias congênitas uterinas em caninos ou felinos são raras, podendo ocorrer atresia, aplasia segmentar, corpo uterino septado, hipoplasia, fusão cornual, cérvix dupla e agenesia de corno uterino (útero unicórnio), sendo esta a mais comum (Pinto Filho et al., 2001;Stone, 2007). Já entre as anomalias adquiridas, encontram-se a hiperplasia endometrial cística/piometra, a hidrometra, a subinvolução dos sítios http://dx

, ambos durante dois dias de pós-operatório. Para avaliação da dor pós-cirúrgica, foram utilizadas as escalas de Melbourne e escala visual analógica (EVA), além de mensurações de glicemia e cortisol sérico. Não houve diferença ao se avaliarem os grupos GM e GMT pela escala de Melbourne nem pela EVA. As mensurações de cortisol não atingiram valores superiores aos de referência para a espécie, enquanto os valores de glicemia não apresentaram variação significativa ao longo do tempo de avaliação nem entre grupos. Com os resultados deste estudo, foi possível concluir que a utilização de meloxicam associado ou não ao tramadol, nas doses e posologias propostas, é eficaz para controlar a dor pós-operatória de cadelas submetidas à OVH laparoscópica com dois portais. Palavras-chave: cão, analgesia, AINES, videocirurgia ABSTRACT The aim of this study was to evaluate the efficacy of meloxicam with or without tramadol for pain control after laparoscopic-assisted ovariohysterectomy (OVH) by two-portal access. Were selected 14 healthy dogs to perform video-assisted OVHs. The animals were divided randomly into two groups (GM and GMT
