Abstract
A fourteen-day-old warmblood colt presented with severe neurological signs of unknown origin. The foal was recumbent and comatose, and showed spastic motion of the head. Computed tomography (CT) examination revealed multiple impression fractures to the left parietal and temporal bones, as well as traumatic brain injury. Three fragments of the temporal bone were dislocated into the cranial vault. The foal was surgically treated within 24 hours of presentation: the fragments were elevated and the largest fragment was fixated with an L-shaped titanium MatrixMidface 0.8 mm reconstruction plate. The brain injury resolved with medical treatment and supportive care. Apart from a localized wound abscess that was drained, postoperative healing was uneventful and the foal regained the ability to ambulate 18 days after surgery. Follow-up CT imaging documented good fracture healing and a favorable development of the soft tissue injuries. Seven months after surgery, the foal was fully recovered and showed no neurological signs.

Abstract
An eleven-year-old, female goat was presented for evaluation of breathing difficulties and epistaxis. Radiographs and computed tomographic (CT) examination of the head revealed the presence of a space-occupying lesion involving the right nasal passage and invading the cranial vault and retrobulbar space. Histologic examination and detection of viral genome from the nasal mass led to the diagnosis of nasal transitional carcinoma with concomitant infection with Enzootic Nasal Tumor Virus (ENTV-2). In this case report, the presence of a nasal transitional carcinoma is described in a goat; a very rare tumor which, to the authors’ knowledge, has not been previously reported in goats. Reverse transcription polymerase chain reaction (RT-PCR) detected the genome of ENTV-2 within the neoplastic tissue, suggesting an infectious etiology.

Abstract
Distal sesamoidean ligament (DSL) injury is a recognized cause of lameness in horses. The purpose of this study was to describe the contrast-enhanced computer tomography (CE-CT) findings in horses with injury to the DSL compared to a control group without injury to the DSL. Medical records of horses referred for CE-CT between 2008 and 2015 were reviewed. Cases were selected retrospectively based on a CE-CT imaging finding of injury to the DSL. Three horses had DSL injury as the only finding, while the remaining horses had one or more concomitant injuries. DSL injury and fetlock trauma and/or suspensory branch desmitis were the most frequent injury combinations. CE-CT can be of value in diagnosing DSL injury. The high number of concurrent DSL and fetlock and/or suspensory lesions suggests that further investigation should be considered when evaluating horses with injuries related to either of these structures.

Abstract
To the authors’ knowledge, this is the first report, in which a simultaneous occurrence of Salmonella-associated multifocal osteomyelitis and intra-abdominal abscessation in a foal presenting with weight loss, diarrhea and fever is described. No evidence of failure of passive immune transfer had been present at birth. Radiographic examination revealed multifocal type P osteomyelitis. Bacterial culture of synovial fluid revealed a Salmonella spp. Antibiotic treatment was adjusted based on the sensitivity results; however without clinical improvement. The foal developed abscess formations within the left femoral region, and finally a Salter Harris type I fracture of the left femur. Euthanasia was elected based on this finding. Post-mortem computed tomography revealed a large mass within the caudal abdomen that extended into the left pelvic and hind limb region, as well as multifocal osteomyelitis. Pathological examination identified the mass as a large abscess with multiple fistula tracts. Salmonella spp. was additionally cultured post mortem.

Abstract
A 15-month-old great Dane dog, showing clinical signs related to hypertrophic osteopathy, was diagnosed radiographically with a mass in the region of the thoracic oesophagus. Exploratory thoracotomy revealed an extensive, highly vascularized and locally invasive oesophageal mass and the presence of nodules in adjacent lung lobes. The dog was humanely destroyed intra-operatively. Histological examination revealed that the mass was an embryonal rhabdomyosarcoma. This is the first report of rhabdomyosarcoma of the oesophagus of a dog. Rhabdomyosarcoma should be considered a differential diagnosis when a mass adjacent to the oesophagus is diagnosed.

Abstract
REASONS FOR PERFORMING STUDY Tarsal pain is a common cause of hindlimb lameness in horses. Diagnosis can usually be made with radiography and ultrasonography; however, in some cases, these techniques are inconclusive and additional imaging is necessary. No studies describing computed tomography (CT) features of different tarsal lesions in horses with tarsal lameness are reported. OBJECTIVES Our aims were as follows: 1) to characterise CT abnormalities in horses with tarsal lameness; 2) to compare CT findings with those from other imaging techniques; and 3) to assess whether CT can help to diagnose tarsal pathology. STUDY DESIGN Retrospective case series. METHODS Computed tomography of the tarsus was performed on 15 horses (n = 17 joints) with tarsal lameness. The horses were divided into 3 groups depending on the reason for CT examination, as follows: 1) other imaging techniques were inconclusive; 2) evaluation of a fracture; or 3) other imaging techniques showed tarsal lesions, and CT was performed to assess whether additional lesions were present. RESULTS Group 1 included 7 horses. Lesions detected with CT included subchondral cyst-like lesions (2 horses); an osteolytic lesion in the cochlea tibiae (one horse); degenerative changes of the distal tarsal joints (2 horses); osteolytic lesions tarsometatarsal joint (one horse); and sclerosis of the third tarsal bone with a lesion of the tarsometatarsal interosseous ligament (one horse). In this group, CT provided information on the character and extent of the lesion that was not available with other imaging techniques. Computed tomography revealed more information about the extent and complexity of the fracture than radiography in Group 2, whereas CT did not provide extra information in Group 3. CONCLUSIONS Focal lesions located between the tarsal bone surfaces are difficult or even impossible to detect with radiography and ultrasonography, but they can be detected and characterised with CT. POTENTIAL RELEVANCE Computed tomography of the tarsus should be considered when radiography and ultrasonography are inconclusive, or for further evaluation of tarsal fractures.

Abstract
The European Union (EU) has 25 member-states and 455 million inhabitants. Statistics on traffic accidents in the EU show that more than 45,000 people are killed annually, including 5200 in France. At the same time, nearly two million persons in the EU require medical treatment for traffic-accident-related injuries, including 109,000 in France. In addition, traffic accidents are the major cause of death of those individuals aged 15 to 24 years. One third of the EU inhabitants will be hospitalized during their life due to a traffic accident with a cost over 160 billion euro (2-3% of the Gross Domestic Product). An important contributing factor to crashes is the use of alcohol and/or illicit drugs or medication when driving, as they exert negative effects on cognition and psychomotor functions. For illicit drugs, abuse of cannabis with or without alcohol is a major concern for the EU. In fact, three million Europeans use cannabis daily and 80% of them drive after use. A number of French studies since 1999 have underlined the high prevalence of cannabis found in the blood of injured or killed drivers. From medical or judicial observations, it is clear that cannabis use increases the risk of traffic accidents. Many groups outside Europe have also shown the association between drug abuse and crashes. The number of casualties related to certain medicines, especially benzodiazepines remains at a high level, particularly in the elderly. In many countries the prevalence of medicinal drugs associated with car accidents is higher than with cannabis. Annex III of the European Union Council Directive of July the 29th 1991 in fact states that a driving license should not be issued to or renewed for applicants or drivers who are dependent on psychotropic substances or use them regularly. Recently, France has categorized the medicinal drugs available in the country by using three pictograms: level one yellow, "be careful"; level two orange, "be very careful"; level three red, "don't drive". It is an important campaign that increases awareness among the public and the medical professionals about the potential dangerous effects of medicinal drugs when driving. The EU objective of reducing the number of fatalities to 25,000 by 2010 will require strengthening measures against the use of alcohol, illicit and medicinal drugs by not well-informed drivers. It is not only a really great challenge, but also a significant investment towards improving public health in France as well as in Europe.

Abstract
By using the selective ACE inhibitor captopril, we studied the effect of the angiotensin converting enzyme (ACE) on larval growth, metamorphosis, and reproduction in a lepidopteran species, the cotton leafworm, Spodoptera littoralis. Captopril was detrimental to adult formation and oviposition, and in female moths it elicited decreasing ecdysteroid levels, but increasing trypsin activities. Our results suggest that captopril downregulates oviposition by two independent pathways. Apparently, oviposition is influenced by a complex interaction of ACE, trypsin activity, and ecdysteroid levels.

Abstract
In Europe, three million people consume cannabis every day. Investigations showed that more than two thirds of drug users drive after having smoked cannabis. Epidemiological studies show that between 0.5% and 8.2% of the general driving population is positive for cannabis. For drivers wounded or deceased as a result of an accident, the percentage varies respectively from 3.3% to 10% and from 2.2% to 8.4%. Finally, very high percentages are found in the studies which analysed the presence of drugs in drivers suspected of driving under the influence of drugs: more than 50% in Austria, Belgium, Germany, Switzerland and the United Kingdom. Six European countries adopted an analytical or 'per se' legislation and the cut-offs vary between 0.3 and 2 ng/mL THC. In the Netherlands, experimental studies carried out after administration of cannabis clearly showed the impairing effects, in particular in the event of simultaneous consumption of cannabis and alcohol. Various research projects financed by the European Union studied the epidemiologic aspects (IMMORTAL), detection by psychotechnical tests (CERTIFIED) and roadside drug detection (ROSITA and ROSITA-2).

Abstract
The role of angiotensin converting enzyme (ACE, peptidyl dipeptidase A) in metamorphic- and reproductive-related events in the Egyptian cotton leafworm, Spodoptera littoralis (Lepidoptera, Noctuidae) was studied by using the selective ACE inhibitor captopril. Although oral administration of captopril had no effect on larval growth, topical administration to new pupae resulted in a large decrease of successful adult formation. Oviposition and overall appearance of adults emerging from treated larvae did not differ significantly from those emerging from non-treated larvae. In contrast, topical or oral administration of captopril to newly emerged adults caused a reduction in oviposition. By evaluating the effect of captopril on ecdysteroid titers and trypsin activity, we revealed an additional physiological role for ACE. Captopril exerted an inhibitory effect on ecdysteroid levels in female but not in male adults. Larvae fed a diet containing captopril exhibited increased trypsin activity. A similar captopril-induced increase in trypsin activity was observed in female adults. In male adults, however, captopril elicited reduced levels of trypsin activity. Our results suggest that captopril downregulates oviposition by two independent pathways, one through ecdysteroid biosynthesis regulation, and the other through regulation of trypsin activity. Apparently, fecundity is influenced by a complex interaction of ACE, trypsin activity, and ecdysteroid levels.
