The case records of 20 horses with tetanus referred to the Ontario Veterinary College-Veterinary Teaching Hospital between 1970 and 1990 were reviewed. The fatality rate was 75%. There was a strong association with previous vaccination and survival (P = .03). Most of the animals had been injured an average of 9 days (range 2 to 21 days) prior to development of clinical signs. Hyperesthesia and prolapse of the third eyelid were the most common clinical signs. Treatment regimens varied during hospitalization; however, all horses received parenteral penicillin, tranquilizers, tetanus toxoid, and antitoxin. Five of the nonsurviving animals were given intrathecal tetanus antitoxin. One animal had seizures as a complication of intrathecal treatment. The prognosis was best for horses that (1) had been vaccinated prior to the injury, (2) responded to the phenothiazine tranquilizers, and (3) did not rapidly (over 24 to 48 hours) become recumbent. Considering the species susceptibility, potential for contaminated wounds, and the increased survival of vaccinated horses, yearly revaccination is recommended.

Rocky Mountain spotted fever (RMSF) was diagnosed in 30 dogs examined at North Carolina State University, Veterinary Teaching Hospital between 1984 and 1997. Historical, physical examination, and laboratory abnormalities were reviewed. Diagnostic criteria included a four-fold rise in antibody titer to Rickettsia rickettsii (R. rickettsii) (n=15) or a single R. rickettsii antibody titer of 1:1,024 or greater (n=15; when this initial titer was determined one week or more after the onset of clinical signs). Fifteen (50%) dogs were greater than seven years of age, and 13 (43%) dogs were between two and seven years of age. There was no sex predilection. Only five (17%) dogs had a history of known tick exposure. Presumably due to delayed diagnosis, dogs with antibody titers of 1:1,024 or greater at the time of presentation had a higher incidence of more severe neurological dysfunction (e.g., ataxia, hyperesthesia, vestibular disease, and seizures) and cutaneous lesions (e.g., hyperemia, edema, petechiae, ecchymoses, and necrosis). Laboratory findings included anemia, leukocytosis accompanied by toxic granulation of neutrophils, hypoalbuminemia, and coagulation abnormalities; signs were generally more severe in the 15 dogs with R. rickettsii antibody titers of 1:1,024 or greater at the time of presentation. Twelve (40%) dogs in this study were severely thrombocytopenic (less than 75 x10(3) platelets/microl; reference range, 200 to 450 x 10(3)/microl), without clinical evidence of fulminant disseminated intravascular coagulation. In this study, the survival rate following R. rickettsii infection was 100%.

A 5-year-old, castrated male mixed-breed dog was presented for paraparesis, ataxia, hyperesthesia, and thrombocytopenia of 5 months' duration and recurrent seizures during the preceding 2 weeks. Multifocal neurological, ophthalmological, pulmonary, and cardiac diseases were identified. Magnetic resonance imaging and cerebrospinal fluid analysis supported a tentative diagnosis of neoplastic or inflammatory disease. A computed tomography-guided biopsy provided both cytopathological and histopathological evidence of intravascular lymphoma. The disease progressed despite chemotherapy with prednisone, L-asparginase, and vincristine. Postmortem histopathological examinations suggested intravascular lymphoma in the central and peripheral nervous systems as well as in multiple other organ systems. This is the first description of an antemortem diagnosis and treatment of intravascular lymphoma involving the central nervous system of a dog.

A 6-month-old, female, mixed-breed dog presented for acute, progressive, flaccid paraplegia and bilateral pelvic-limb hyperesthesia. A lymphocytic pleocytosis with 366 mg/dL protein was found on cerebral spinal fluid (CSF) evaluation. Electromyography (EMG) demonstrated positive sharp waves and fibrillations in the left pelvic limb; the M wave of the left sciatic nerve was not obtainable by nerve stimulation. Seizures and dementia began during recovery from anesthesia. Six days after onset of paralysis, the dog was euthanized. Direct fluorescent antibody testing of the brain was positive for raccoon rabies virus. This case demonstrates clinical evaluation, CSF analysis, and EMG in an animal with rabies meningoencephalomyelitis.

Three dogs (two Rottweilers and a Flat-coated retriever) showed various neurological signs, including apathy, depression, circling, a partial decrease in functions associated with cranial nerves, seizures, hyperaesthesia, proprioceptive deficits, and increased spinal reflexes. In all three cases, necropsy revealed a solid, distinct, white mass in the brain and multiple, poorly demarcated, firm nodular proliferations in the lung; in one case the liver was also affected. Histopathological examination showed loosely aggregated, pleomorphic cells, with abundant eosinophilic cytoplasm. The neoplastic cells sometimes contained vacuoles or phagocytized cells. Binucleated and multinucleated giant cells, and mitotic figures, were common. Immunohistochemically, the tumour cells reacted strongly for lysozyme and vimentin, but there was no reaction for S-100 protein, cytokeratin, CD3 or CD79a. The histological and immunohistochemical examinations indicated a histiocytic origin of the tumour cells and malignant histiocytosis was therefore diagnosed.

Alpha-chloralose (AC) is an anaesthetic compound also used as a rodenticide, and has dose-dependent central nervous system mixed effects of excitation and depression. The objectives of this study were to detail the clinical and clinicopathological characteristics, as well as the treatment and prognosis, of AC toxicosis in dogs and cats. Medical records were retrospectively reviewed for AC poisoning between the years 1989 and 2004, and 33 dogs and 13 cats were included in the study. The most common clinical signs were seizures, muscle tremor, hyperaesthesia, hypothermia, salivation, myosis, stupor, coma and ataxia. Coma was more common, while salivation and ataxia were less common in cats compared to dogs. Although hypothermia was very common, especially in cats (90.9%), hyperthermia was frequently observed in dogs (21%). Treatment in all patients was supportive and symptomatic, and the most commonly used anticonvulsants were diazepam and barbiturates; however, severe unresponsive seizures in three dogs had to be controlled with inhalant gas anaesthesia. The hospitalisation period was 1-3 days, and the overall mortality rate was 6.5%. Alpha-chloralose poisoning seems to have a favourable prognosis in dogs and cats.

Four incidents of Duranta erecta (golden dewdrop, Sheena's Gold, Geisha Girl) poisoning affecting nine dogs and a cat produced drowsiness, hyperaesthesia and tetanic seizures in all affected animals with evidence of alimentary tract irritation (vomiting, gastric and intestinal haemorrhage, diarrhoea, melaena) in five dogs and the cat. Fruits and leaves were seen to be eaten by affected animals. Therapy was successful in three of the dogs. Repeated diazepam doses and, in some cases, additional pentobarbitone or propofol anaesthesia, were successful in controlling seizures.

Phacomatosis pigmentokeratotica (PP) is a mosaic disorder that represents a distinct epidermal naevus syndrome. Its defining features are an epidermal naevus that is usually of the sebaceous type and a speckled lentiginous naevus arranged in a chequerboard pattern. In addition, there are neurological, ophthalmological and skeletal abnormalities, including limb hemiatrophy with muscular weakness, ptosis, seizures and ipsilateral segmental hyperaesthesia and hyperhidrosis. We report a 44-year-old man with an extensive epidermal naevus and an ipsilateral speckled lentiginous naevus. He also had ipsilateral right leg hypertrophy and a suprasellar dermoid cyst with associated neurological abnormalities. We propose that this case represents an unusual example of PP.

Forty-two cases of feline permethrin toxicity treated at a referral hospital in Sydney, Australia were retrospectively reviewed. In most cases canine permethrin spot-on (PSO) flea products had been directly applied to affected cats. Most presented during summer and there was an increase in cases during the 2007/2008 period. Clinical signs included; tremors/muscle fasciculations (86%), twitches (41%), hyperaesthesia (41%), seizures (33%), pyrexia (29%), ptyalism (24%), ataxia (24%), mydriasis (19%) and temporary blindness (12%). Treatment involved decontamination, anticonvulsants and supportive care. Methocarbamol was not used. Complications occurred in 33% of cats and included: hypothermia (29%), electrolyte abnormalities (26%), aspiration pneumonia (12%), hypoproteinaemia (12%), anaemia (5%), apnoea (7%), respiratory arrest (5%), cardiorespiratory arrest (2%), pleural effusion (2%), urinary tract infection (2%) and corneal ulceration (2%). One cat was euthanased. Feline permethrin toxicity may result in severe clinical signs requiring intensive treatment. Despite prominent label warnings, cases of feline permethrin toxicity continue to occur in Australia and may be fatal.

West Nile Virus (WNV) is an enveloped, positive-sense RNA virus belonging to the genus Flavivirus, antigenically related to the Japanese encephalitis complex in the family Flaviviridae. The principal vectors are mosquitoes, in particular Culex spp, and virus amplification seems to occur in susceptible birds that are the principal vertebrate reservoir hosts, whereas humans, horses and other vertebrates are considered incidental or dead-end hosts. The first Italian equine outbreak was reported in late summer of 1998 in Tuscany, in the area surrounding the Fucecchio marshes, where 14 clinical cases of WND in housed equines were recorded. In 2011 WNV appeared for the first time in Sardinia, representing the first clinical cases in equines in Italy in 2011. The outbreak occurred both in humans and in equines. The serological survey performed on 253 equines living in the province of Oristano detected a total of 87 IgG-positive subjects. Among them, 46 horses showed neurological signs such as ataxia, paresis, paralysis, hyperesthesia, muscle fasciculations, seizures, or fever. Nine of them died or were euthanized. In forthcoming years, surveillance of wild birds and insects will be used to forecast the extension and spread of WNV. The information gathered will be used to direct or optimise strategies intended to prevent virus transmission.
