AbstractCanine African Trypanosomosis (CAT) is a rarely described disease with frequently lethal outcome. A 5-year-old female mongrel dog weighing 22 kg was presented in Austria due to unilateral uveitis, pancytopenia, and anorexia 4 months after return from a trip through Western Africa. Trypanosoma spp. flagellates were detected in a blood smear and identified as Trypanosoma congolense forest type by PCR. Initial treatment with imidocarb and miltefosine led to clinical improvement but only isometamidium chloride hydrochloride applied intramuscularly led to complete eradication of the pathogen from the dog’s blood 4 months later.

A seven-year-old female mongrel dog was presented at the Sokoine University of Agriculture Teaching Animal Hospital for second opinion regarding a progressive swelling of the right hind limb of two months duration. Clinical examination revealed a loss of body condition, tachypnea and tachycardia, a painful immobile solid mass of 20 cm x 14 cm x 10 cm located on the right stifle joint, leucocytosis, and anaemia. Radiographic examination of the joint revealed marked soft tissue swelling with amorphous areas of mineralization and complete destruction of the proximal tibia. Smooth and solid periosteal reaction was seen around the tibia and fibula with a Codman’s triangle. Multiple nodules and a mass with soft tissue opacity were seen in the lung fields. Post-mortem examination revealed separation of tibia and fibula, softening of the proximal parts of the tibia, and complete integration of the proximal region of the two bones and articular tissues into the surrounding muscular tissues. Multifocal nodular lesions of variable sizes were mostly found in the lungs and partly in the liver. Histologically, predominantly oval and round cells with variable nuclear sizes and moderate mitoses were observed in tissue samples from the joint, lungs and the liver although some parts of the lung metastases showed both round and spindle shaped tumor cells. Clinical profile is suggestive of aggressive biphasic (spindle and epithelial) type of synovial cell sarcoma with lung and liver metastasis. Early radiographic and biopsy examination of persistent musculoskeletal nodules is recommended for early diagnosis and interventions.

Ectrodactyly is the term used to designate cases in which soft and bone tissue separation within the distal region of the thoracic limbs is present. It is observed in particular below the metacarpal bones and extending to the radius and ulna. In addition, it can often be associated with ipsilateral elbow luxation. We describe a case of ectrodactyly in a 3-month-old mongrel dog, where bone and soft tissue separation occurred between the third and fourth digits, extending proximally to the carpal region. We identified shortening of the ulna without elbow luxation. The dog was subjected to a surgical procedure comprising bone and soft tissue reconstruction and ulnar diaphyseal osteotomy, which was fixed using a Steinmann pin in the intramedullary canal, maintaining a distance of 1 cm between the two ulnar fragments. Two distal phalanges were removed because it was not possible to reposition them anatomically in the limb. The dog walked with mild lameness nine months after surgery.

In comparing gas exchange responses of the methacholine- (MCh) challenged mongrel dog with leukotriene receptor blockers and placebo at different inspiratory O2 fractions (FIO2), we previously noted systematically different values of cardiac output as a function of drug administration and/or FIO2. This confounds identification of the effects of FIO2 and/or drugs on gas exchange, because shunt is well known to vary directly with cardiac output when other factors are equal. Accordingly, in six dogs we examined the dependence of combined shunt and low ventilation-perfusion (VA/Q) blood flow (“shunt”) on cardiac output in the MCh-challenged mongrel dog. Two dogs breathed 100% O2, another two breathed room air, and the final pair breathed 12% O2 while cardiac output was altered several times by sequentially opening and closing arteriovenous fistulas every 10 min for approximately 90 min after a standard MCh challenge. On 100% O2, shunt increased by 11.0% of the cardiac output per 1-l/min increase in cardiac output. On room air, the value was 7.4%. With 12% O2 breathing shunt rose by only 2.2% per 1-l/min rise in blood flow. This FIO2 -dependent behavior of the shunt-cardiac output relationship was highly reproducible, both within and between animals. It suggests that the increase in shunt with cardiac output depends more on vascular tone of noninjured areas than on tone of the low VA/Q regions (which are hypoxic at all FIO2 values).

Abstract BACKGROUND: Watertight repair of the dura is imperative after neurosurgical procedures involving the brain or spinal cord because inadequately treated leakage of cerebrospinal fluid (CSF) from punctured dura can have serious consequences such as meningitis, arachnoiditis, or epidural abscess. OBJECTIVE: To assess the efficacy of Evicel Fibrin Sealant (Human) to prevent CSF leakage using a 2.0-cm durotomy mongrel dog repair model and to compare the tissue response with Tisseel (a fibrin sealant) and Duraseal (a synthetic polyethylene glycol [PEG] hydrogel sealant). METHODS: The canine durotomy repair model was used. This well-characterized model assesses the ability of sealants to achieve intraoperative watertight seals of the dura mater, as well as long-term safety and efficacy. This study included 27 mongrel dogs and had a 28-day duration. RESULTS: The 3 sealants were 100% effective in preventing CSF leakage intraoperatively at 15 mm Hg. The 2 fibrin sealants were 100% effective in postoperative sealing; the PEG hydrogel was not. Microscopically, the tissue changes induced by Evicel at the durotomy site were similar in nature except for foamy macrophages seen only with the PEG hydrogel. The extent and severity of adhesions at 28 days were less with the fibrin sealants than with the PEG hydrogel. CONCLUSION: Evicel, a fibrin sealant, was safe and effective in achieving and maintaining a watertight seal of the dura. The performance of the fibrin sealants was similar to that of the synthetic PEG hydrogel sealant with the exception of a Duraseal seal, which leaked.

This study is aimed at synthesizing all available evidence on vertical alveolar osteogenesis distraction (VAOD) in animal trials to determine whether the animal model used and its handling influence or not, and find which is the most appropriate animal model for this specific technique. This systematic review has been carried out following the PRISMA statements. Bibliographic sources have been consulted manually by two reviewers. Risk of bias was assessed using a version of the Newcastle-Ottawa-Scale (NOS). The selection criteria established by expert researchers were applied in order to decide which studies should be included in the review. Twenty-six studies met the inclusion criteria and were included in the review. Twenty-four of them had a high quality (score between 7 and 9), two medium quality (score between 4 and 6), and none low quality (score between 1 and 3). The highest possible score was 9 (using the NOS). Six studies complied with all NOS criteria. The animal model has been seen to influence the results, leading to failure in some cases. The most used animal model on VAOD, with fewer complications, was the Mongrel dog. The use of the pig and minipig is not recommended, due to the difficulties in handling and complications encountered.
