Abstract
A 9‐year‐old intact female toy poodle was presented with oedema around the neck, including pus and cutaneous necrosis, 2 days after starting firocoxib treatment and placement of a cervical collar for intervertebral disc disease. Cytology of the pus revealed predominantly mature neutrophils with fewer macrophages and lymphocytes, indicating sterile inflammation. Although a skin biopsy could have provided more diagnostic information, it was not performed at presentation. Firocoxib treatment was discontinued, and immunosuppressive therapy including cyclosporine was initiated, which significantly alleviated the skin lesions. The dog recovered fully in 7 weeks. The final diagnosis was a possible cutaneous adverse drug reaction to firocoxib based on history, clinical signs and response to therapy.

Abstract
Abstract
A four-year-old intact male Labrador retriever was presented with acute onset of ulcerative lesions around both eyes, on the mucocutaneous junctions around the muzzle and nares, and on the lateral aspects of paw pads. All lesions were symmetrical and well demarcated. The rest of ocular and systemic examination was unremarkable. The onset of lesions was acute and coincided with an episode of intense hunting in switchgrass. Similar lesions were present in another dog used in the same hunting trip. The clinical presentation was suggestive of a possible immune-mediated skin disease. However, the patient responded to systemic antibiotic treatment with full recovery without recurrence upon cessation of therapy. Traumatic origin should be included into differential diagnosis of mucocutaneous ulcerative lesions presenting as a possible immune-mediated skin disease.

Abstract
OBJECTIVE To report the outcome of treatment of uncomplicated allergic reactions in dogs with diphenhydramine vs diphenhydramine plus glucocorticoid and to determine the incidence rate of uncomplicated allergic reactions DESIGN: Retrospective study between January 1, 2012 and August 15, 2018. SETTING Privately owned, 24-hour emergency and specialty referral veterinary hospital. ANIMALS Eight hundred and eighty cases of dogs treated for uncomplicated allergic reaction with diphenhydramine alone or in combination with a glucocorticoid. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Two hundred ninety-nine dogs were treated with diphenhydramine alone, and 581 were treated with diphenhydramine plus Dex SP. There was no difference between the 2 groups for response to initial therapy, need for additional veterinary intervention after discharge, or persistent signs at follow-up. The cumulative incidence of emergency department presentation for uncomplicated allergic reaction in this hospital was 1.2%. CONCLUSIONS There was no difference in measured outcomes between dogs treated with diphenhydramine alone vs those treated with a glucocorticoid in addition to diphenhydramine in this population of dogs.

Abstract
Studies using the Mouse Grimace Scale have shown that for many NSAID, including meloxicam, minimal doses of at least 20 mg/kg may be necessary to achieve adequate peri- and post-operative analgesia in mice. However, more data are needed to determine whether such NSAID doses exceed the threshold for gastrointestinal ulceration or induce other relevant pathology. We administered equal volumes of saline or injectable meloxicam (1 or 5 mg/mL) at a dose of 20 mg/kg SC to 20 young adult male and female C57BL/6N mice daily for 6 d and performed necropsies on all mice on the seventh day. Mice given 5 mg/mL meloxicam subcutaneously developed significantly more severe pathology at the injection site than saline controls. Pathology was characterized by full-thickness epidermal necrosis; cavitary lesions within subcutis, muscle, or fat; steatitis; and myositis. Mice that received 1 mg/mL meloxicam subcutaneously developed lesions that were qualitatively similar but far less severe than those after 5 mg/mL. However, no pathologic lesions typically associated with NSAID toxicity, such as gastric ulceration and liver and kidney lesions, were seen. These results demonstrate that although meloxicam injected subcutaneously causes concentration-dependent skin pathology at the injection site, a dose of 20 mg/kg can be safely administered subcutaneously at a concentration of 1 mg/mL for as long as 6 d.

Abstract
Case summary A 9-year-old male neutered Devon Rex cat presented with bilaterally symmetrical ulcerative lesions with mucopurulent exudate that developed rapidly. The lesions were apparent on the axillae, ventral abdomen and inguinal areas. The cat was systemically well. Piroxicam was being administered for palliative treatment of a previously diagnosed salivary adenocarcinoma. Histopathology revealed severe extensive epidermal ulceration with focal dyskeratotic keratinocytes in the stratum granulosum without lymphocyte satellitosis. Resolution of skin lesions was observed after discontinuing piroxicam. Similar lesions developed after previous piroxicam administration, further suggesting a possible adverse reaction to this drug. In addition, the Naranjo score indicated that piroxicam was a probable cause for the ulcerative skin lesions. Relevance and novel information This is the first report of piroxicam, a non-steroidal anti-inflammatory drug, as a probable cause of ulcerative skin lesions in a cat.

Abstract
Brucellosis is one of the most common contagious and communicable zoonotic diseases with high rates of morbidity and lifetime sterility. There has been a momentous increase over the recent years in intra/interspecific infection rates, due to poor management and limited resources, especially in developing countries. Abortion in the last trimester is a predominant sign, followed by reduced milk yield and high temperature in cattle, while in humans it is characterized by undulant fever, general malaise, and arthritis. While the clinical picture of brucellosis in humans and cattle is not clear and often misleading with the classical serological diagnosis, efforts have been made to overcome the limitations of current serological assays through the development of PCR-based diagnosis. Due to its complex nature, brucellosis remains a serious threat to public health and livestock in developing countries. In this review, we summarized the recent literature, significant advancements, and challenges in the treatment and vaccination against brucellosis, with a special focus on developing countries.

Abstract
Inflammation of the blood vessel wall has been reported infrequently in dogs, and it may occur without apparent cause (primary vasculitis) or as a pathologic reaction to a range of initiating insults (secondary vasculitis). The aims of our study were to report histologic, clinical, and survival data from a large series of cases with primary and secondary vasculitis, and to compare the clinical parameters and outcome data between groups. Clinical data was collected retrospectively from the medical records of 42 client-owned dogs with a histologic diagnosis of primary or secondary vasculitis, and follow-up information was obtained. Cases were grouped according to clinical and histologic descriptors, and biochemical, hematologic, and survival data was compared between groups. Several forms of primary vasculitis were observed, and vascular inflammation was observed in conjunction with numerous other diseases. Female dogs were more likely to develop primary vasculitis, and serum globulin concentration was greater in dogs with primary vasculitis compared to those with underlying disease. All dogs with primary vasculitis of the central nervous system died or were euthanized shortly after presentation, but other forms of primary vasculitis could be managed effectively. In conclusion, presentation of clinical cases in this series was variable, and there did not appear to be well-defined vasculitic syndromes as described in people.

Abstract
Cutaneous vasculitis is an inflammatory process targeting blood vessels. Underlying factors include drugs, infectious diseases, adverse reactions to food, malignancies, and immune-mediated diseases. Vasculitis is a reaction pattern warranting a workup to identify triggers. Presenting symptoms include purpura, pitting edema, and skin ulcerations. Constitutional signs include fever, depression, and anorexia and seem to be present in the majority of patients. Once a diagnosis is confirmed, treatment and follow-up must be tailored to the individual. High-dose immunosuppressive medications are only recommended once infectious diseases capable of producing a similar constellation of clinical signs have been ruled out.

Abstract
A 59-yr-old female Nile hippopotamus (Hippopotamus amphibius) was diagnosed and treated for severe dermatitis. Lesions included large areas of depigmentation, erosions, and ulcerations on glabrous skin areas, limbs, and perineal region. Histopathologic lesions included a markedly edematous, focally eroded, ulcerative to necrotic epidermis; foci of keratinocyte apoptosis; and a mixed suppurative dermatitis. Most of the dermal vessels had variable hyalinized walls with plump endothelial cells and frequent intramural neutrophils, and some vessels had vascular thrombi consistent with vasculitis. Culture of the lesions yielded beta-hemolytic Streptococcus, Morganella morgannii, and Enterococcus sp. The hippopotamus was successfully treated with sulfamethoxazole and trimethoprim, amoxicillin, and pentoxifylline for more than 2 mo, and the condition did not recur over the subsequent 16 mo.

Abstract
Adverse drug reactions (ADRs) can be dose dependent or idiosyncratic. Most idiosyncratic reactions are believed to be immune-mediated; such drug hypersensitivities and allergies are unpredictable. Cutaneous reactions are the most common presentation of drug allergies. In veterinary medicine it can be difficult to assess the true prevalence of adverse drug reactions, although reports available suggest that they occur quite commonly. There are multiple theories that attempt to explain how drug allergies occur, because the pathogenesis is not yet well understood. These include the (pro)-hapten hypothesis, the Danger Theory, the pi concept, and the viral reactivation theory. Cutaneous drug allergies in veterinary medicine can have a variety of clinical manifestations, ranging from pruritus to often fatal toxic epidermal necrolysis. Diagnosis can be challenging, as the reactions are highly pleomorphic and may be mistaken for other dermatologic diseases. One must rely heavily on history and physical examination to rule out other possibilities. Dechallenge of the drug, histopathology, and other diagnostic tests can help to confirm the diagnosis. New diagnostic tools are beginning to be used, such as antibody or cellular testing, and may be used more in the future. There is much yet to learn about drug allergies, which makes future research vitally important. Treatment of drug allergies involves supportive care, and additional treatments, such as immunosuppressive medications, depend on the manifestation of the disease. Of utmost importance is to avoid the use of the incriminating drug in future treatment of the patient, as subsequent reactions can be worse, and ultimately can prove fatal.

Abstract
Iragüen, D., Urcelay, S., San Martín, B. Pharmacovigilance in veterinary medicine in Chile: a pilot study. J. vet. Pharmacol. Therap.34, 108-115. In Chile, there is no present government policy to survey and analyse adverse drug reactions (ADRs) in the field of veterinary medicine. The intent of this study is to assess, for the first time, ADR frequency in treated animals. To this purpose, a 6-month period pilot study based on WHO recommendations was conducted to monitor ADRs in cats and dogs for frequently used drugs and common labelled signs. Of a total of 149 detected ADRs, 29 (6 in cats and 23 in dogs) were notified by means of ADR report forms, while the rest was identified after reviewing patient clinical records, thus evidencing strong under-reporting problems. More than 70% of ADRs were related to antimicrobials, vaccines and tranquilizers. In dogs, there was a significant effect on ADRs' presentation when acepromazine, amoxicillin, carprofen, ivermectin, sextuple vaccine (polyvalent vaccine that confers immunity against canine distemper virus, canine parvovirus, Leptospira canicola, L. icterohemmoragiae, canine adenovirus type 2 and canine parainfluenza virus) and phytomenadione (subcutaneous injection) were administered. In the case of cats, a significant influence on ADRs was detected when acepromazine, amoxicillin or vitamin K was administered. Present results suggest the need for a pharmacovigilance programme in veterinary medicine for timely ADR-presenting drug detection and drug safety improvement.
