Treatment of oral squamous cell carcinoma in a horse by surgical debulking followed by metronomic chemotherapy          下载免费PDF全文

A 19‐year‐old Quarter Horse gelding presented with a 6‐week history of hypersalivation, halitosis and dysmasesis. Oral examination revealed retention of food and saliva and the presence of a raised, nodular, 6 × 7 cm, ulcerated mass on the dorsal surface of the tongue base. The mass was confirmed histologically as squamous cell carcinoma. Complete resection of the mass was not possible and surgical laser debulking was followed 15 days later by chemotherapy with a combination of meloxicam and cyclophosphamide in metronomic regimen. After one week, there was a significant improvement in clinical signs and food consumption returned to normal. Therapy was well tolerated with no alteration in haematological or urinalysis parameters. After 5 months of excellent life quality, the horse showed progressive difficulties in mastication and swallowing. Endoscopic examination showed extension of the tumour to all the aboral aspect of the tongue and, with the owner's consent, the patient was subjected to euthanasia. This is believed to be the first report on the combined use of meloxicam and cyclophosphamide in a metronomic fashion for management of an oral squamous cell carcinoma in a horse. Since metronomic therapy is less expensive than conventional chemotherapy, easily administrable and well tolerated, it should be considered as a possible treatment option for nonresectable equine malignant tumours.  相似文献   

Alternative method to facilitate resolution of paraphimosis after penile trauma in the horse          下载免费PDF全文

E. De Brouwer  T. Ribera  F. Climent  M. Prades 《Equine Veterinary Education》2017,29(12):655-658

Inflammation associated with traumatic injury to the penis is characterised by pain, heat and oedema. Ensuing penile swelling interferes with retraction of the penis into the prepuce, resulting in paraphimosis. This report describes the use of a 5 l capacity pressure infusion bag to reduce penile oedema in three horses. This technique provided complete resolution of oedema and associated paraphimosis in approximately 1 h. The use of the bag, along with an abdominoinguinal bandage, a plastic funnel suspensory device, or a penile repulsion device (Probang) to avoid recurrence, offers a novel treatment that may be performed with the horse sedated.  相似文献   

Preputial fibroma in a gelding          下载免费PDF全文

An 11‐year‐old gelding presented with a large mass located in the dermis of his preputium that surrounded the penis completely. This mass was first noted years ago but did not increase in size. Histological examination diagnosed a fibroma. No treatment was initiated since no signs of discomfort were noticed and the gelding was performing at a high level in competitive showjumping. Next to skin tumours, tumours of the penis and preputium are most common. Most frequently, squamous cell carcinomas and sarcomas are diagnosed. Although fibromas can develop anywhere in connective tissue, a preputial location of a fibroma in a gelding is rare. Differential diagnosis and possible treatment options are discussed.  相似文献

In the last decade, progenitor cells isolated from dissociated endometrial tissue have been the subject of many studies in several animal species. Recently, endometrial cells showing characteristics of mesenchymal stem cells (MSC) have been demonstrated in human, pig and cow uterine tissue samples. The aim of this study was the isolation and characterization of stromal cells from the endometrium of healthy bitches, a tissue that after elective surgery is routinely discarded. Multipotent stromal cells could be isolated from all bitches enrolled in the study (n = 7). The multipotency of cells was demonstrated by their capacity to differentiate into adipocytic, osteocytic and chondrocytic lineages. Clonogenicity and cell proliferation ability were also tested. Furthermore, gene expression analysis by RT‐PCR was used to compare the expression of a set of genes (CD44, CD29, CD34, CD45, CD90, CD13, CD133, CD73, CD31 CD105, Oct4) with adipose tissue‐derived MSC. Stromal cells isolated from uterine endometrium showed similar morphology, ability of subculture and plasticity, and also expressed a panel of genes comparable with adipose tissue‐derived MSC. These data suggest that endometrial stromal cells fulfil the basic criteria proposed by the “Mesenchymal and Tissue Stem Cell Committee of the International Society for Cellular Therapy” for the identification of mesenchymal stem cells. Although endometrial mesenchymal stem cells (EnMSC) showed a lower replicative ability in comparison with adipose tissue‐derived MSC, they could be considered a cell therapeutic agent alternative to adipose tissue or bone marrow‐derived MSC in dog.  相似文献   

Prevention of intestinal parasites in a tri‐border area of Latin America: Children perceptions and an integral health education strategy          下载免费PDF全文

To investigate knowledge of school‐aged children and their perception on intestinal parasites, and to assess knowledge reconstruction on prevention practices after specific training in the subject. We performed an activity package that included the analysis of children's drawings of intestinal parasites, and information and communication technologies (ITCs) to transfer knowledge about these pathogens and prevention measures. Retrieval learning activities were performed to fixation of general and specific prevention and control measures.Overall, we found that there is a knowledge gap in many aspects of parasite biology and ecology, and therefore on the risk of infection and acquisition mechanisms. After ITCs, the children improved their knowledge over non‐trained children.The approaches used to transfer knowledge and for learning, fixation were valuable tools for incorporating changes in misconceptions and in the deep‐rooted habits that favour entero‐parasitic diseases. This has important implications for the specific design of future education materials and campaigns. Understanding of perceptions helps to provide justifications and knowledge to achieve changes in unhealthy habits, and it constitutes the basis for the transformation of many risky practices.  相似文献
