The aim of this study was to provide a beneficial treatment effect of mesenchymal stem cell products derived from the canine amniotic membrane (AM-MSC) on the complicated wound healing process in dogs. AM-MSCs were characterized in terms of morphology, phenotypic profile, and multilineage differentiation potential. The in vitro study of the effect of canine amniotic mesenchymal stem cell conditioned media (AMMSC-CM) on a primary skin fibroblast cell culture scratch assay showed a decrease in the measured scratch area of about 66.39% against the negative control (Dulbecco’s Modified Eagle’s Medium—32.55%) and the positive control (Dulbecco’s Modified Eagle’s Medium supplemented with FGF2, N2, B27, and EGF—82.077%) after 72 h treatment. In the experimental study, seven dogs with complicated nonhealing wounds were treated with a combination of antibiotics, NSAIDs, and local AMMSC-CM application. After 15 days of therapy, we observed a 98.47% reduction in the wound surface area as opposed to 57.135% in the control group treated by conventional therapy based on debridement of necrotic tissue, antibiotic therapy, pain management, and change of wound dressing.

Background: Surgical wound dehiscence (SWD) is defined as a complete or partial separation of the surgical incision site after surgery and represents a serious complication in soft tissue surgery. Case presentation: We present a clinical case of wound dehiscence in a 7-month-old dachshund. The primary cause was an attack by another dog, leading to the development of a deep bite wound in the back area perforating the anus and numerous minor injuries in the same area. After initial treatment and apparently good general health, numerous necrotic foci were observed during wound cleaning on the 3rd day after treatment. The wound was subsequently revised and an experimentally developed biomaterial based on chitosan in combination with manuka honey was applied. The use of this combination resulted in an accelerated healing process and almost complete closure of the wound already on the 12th day after application. Conclusions: This case demonstrates and simultaneously points to the promising possibilities of using chitosan-based biomaterials and honey as natural products for the successful treatment of wounds and management of postoperative complications.

This case report describes the immunohistochemical examination of poorly differentiated squamous cell carcinoma (SCC) in a sixteen-year-old Slovak Warmblood gelding. Clinical examination detected a dull, painless percussion in frontal and maxillary sinuses. The left arch of the mandible had an irregular surface with a painful tap. The submandibular lymph nodes were bilaterally asymmetric with left sided hypertrophy, smooth to palpation, hard and painless. The tumorous mass was overgrown through the laryngeal mucosa, not observed in the oral cavity. The patient was in a poor clinical condition and was euthanized six months after the first clinical signs were observed. Histological examination of the samples taken from the tumorous mass showed the presence of proliferated cells of epithelial origin. The histological finding of the mandible showed focal osteolysis with multinuclear cells, which were bordered by mesenchymal tissue and a moderately dense collagen. Immunohistochemically, tumorous cells were positive for p63 and cytokeratin AE1/AE3. Protein p63 confirmed the metastatic spread of the tumour and was demonstrated to be a suitable marker for poorly differentiated SCC.

In the present work, we describe the clinical–pathological case of an 11-month-old Border Collie dog, which was presented by its owner to a private veterinary clinic for the purpose of determining the diagnosis and subsequent therapy. The owner reports anamnestic data of abdominal enlargement, persistent apathy, fatigue, and vomiting. A complete examination of the patient was performed, consisting of clinical, hematological, and biochemical blood tests, X-ray, and USG examinations. Based on the findings, a probatory laparotomy was indicated, during which a large multi-lobular cystic irregular mass was detected, affecting the entire liver parenchyma, including macroscopic metastatic foci of the omentum and diaphragm. Due to the inoperable finding, the patient was humanely euthanized during the surgical procedure. Subsequently, an autopsy was performed with the collection of samples for histopathological and PCR examination of the tissue. Serological examination was also performed. The results confirmed a rare generalized form of alveococcosis (Echinococcus multilocularis) in the dog as an intermediate host.
