Seizure-like reactions induced by propofol in dogs: prevalence and clinical insight

This study investigated the incidence of seizure-like reactions induced by propofol in dogs treated at the Veterinary Hospital of UNIUBE over three years, highlighting its low frequency and the scarcity of reports in veterinary literature. During the study period, the prevalence of these reactions was 0,02% among dogs receiving propofol as a sedative or anesthetic agent. One case was described and discussed: a three-year-old female dog presented the reaction during anesthetic induction for elective ovariohysterectomy, was treated with ketamine, and showed resolution of signs, allowing the surgery to proceed without complications. Although rare, seizure-like reaction can occur in healthy, young dogs. Several theories have been proposed to explain its mechanism, including propofol antagonism to glycine receptors, stimulation of subcortical dopaminergic areas, and toxicity of metabolites. Ketamine treatment was effective in stopping the crisis in this specific case. In conclusion, seizure-like reaction is a reality in veterinary surgical centers, and ketamine administration is an effective option for its treatment.

Recurrent cerebrovascular accidents caused by intravascular lymphoma in a dog

An eight-year-old, neutered male labrador was presented with recent recurrent vestibular episodes. MRI was consistent with multiple lacunar ischaemic infarcts in the thalamus and medulla oblongata. The imaging diagnosis was...

Multiple lipoma in a stray donkey (first report in veterinary literature)

Lipoma is a common benign tumor of well-differentiated adipocytes, which seen in most domestic animals. A 5-year-old male stray donkey was necropsied for educational purposes in the veterinary hospital of Shahid Bahonar University of Kerman. The animal was cachectic, but normal in the other respects. At necropsy, the tumors were well-circumscribed, unencapsulated, soft white to yellow masses very similar to normal fat tissue. These masses were attached to stomach, small intestine, and pancreas. Microscopic findings indicated that the cells of the tumor were identical to those in normal fat tissue. Large vacuoles replaced the cytoplasm, with peripheralization of the nuclei. No necrosis, inflammation, dystrophic calcification, and fibrosis were seen. Based on the aforementioned macroscopic and histopathologic findings multiple lipoma was diagnosed. Based on author’s knowledge, multiple lipoma in various organs such as the stomach, intestine, and pancreas has not been reported in animals, especially in donkey. In conclusion, we report here a very rare case of multiple lipoma (lipomatosis) with no clinical signs in a stray donkey.

Manganese-responsive congenital carpus valgus in a calf (first report in veterinary literature)

A 4-day-old female Iranian cross-breed calf with a history of weakness, ataxia, difficulty in moving, and congenital abnormal position of forelimbs was referred to the Veterinary Clinic of Shahid Bahonar University of Kerman. In clinical examination weakness, ataxia, difficulty in moving, and carpus valgus deformity were observed. Vital signs, hematological indices, and serum concentrations of electrolytes, minerals, total protein, albumin, and trace elements were normal, but serum concentration of manganese was low. Because of carpus valgus deformity and low level of serum concentration of manganese, congenital manganese deficiency was suspected. Manganese sulfate was administered orally at a dose rate of 50 mg/day for 2 weeks. After the treatment, all clinical signs subsided. Radiography of forelimbs after treatment revealed no abnormality. Carpus valgus due to manganese deficiency has not been reported previously, and this is first report in veterinary literature. In the present report, low serum concentration of manganese and response to manganese supplementation confirmed that the cause of carpus valgus was manganese deficiency. The pregnant cow (the mother of the present calf) had low serum concentration of manganese. She was fed on corn silage, which was low in manganese during pregnancy. The cause of carpus valgus is believed to be maternal manganese deficiency.

Congenital lipoblastoma in a neonate calf: first report in veterinary literature

Lipoblastoma is a rare benign tumour of adipose tissue that usually occurs in young children. Although around 100 cases of lipoblastoma have been reported in humans, no report has been previously described in animals. This case report describes the clinical and histopathological findings of a congenital lipoblastoma located at the tail base of a 2-day-old male calf. Grossly, the mass was pink with a partly ulcerated and haemorrhagic surface. The calf showed no neurological deficits. Radiographs of the vertebral column revealed no abnormalities, and surgical excision was performed. Histopathology of the mass was consistent with lipoblastoma. The calf was followed up for 13 months and found to be healthy with no signs of recurrence. To the best of the authors' knowledge, this is the first case of lipoblastoma in the veterinary literature. Lipoblastoma should thus be considered in the differential diagnosis list for congenital adipose tissue tumours in animals.

Apoplectiform Septicemia in Turkeys

JUDGING from the very few reports in veterinary literature, one is led to believe that streptococcic infection in poultry is of rather rare occurrence. It seems, however, perfectly plausible that with more diligent examination of autopsy specimens, that is by recourse to the microscope and to bacteriological methods for the differentiation and diagnosis of septicemic diseases of fowl, streptococcic infection may be more frequently demonstrated.To the writer’s knowledge, streptococcicosis has not before been reported from turkeys. The polymorphic streptococcus observed in turkeys by Krage and Weissgerber (1924) is said to have been identical, in all probability, with the Corynebacterium pseudotuberculosis rodentium. As a matter of fact, the American literature has been silent on apoplectiform septicemia for nearly twenty-five years. That an interesting observation, made several years ago, while affiliated with the Veterinary Department of the North Dakota Agricultural Experiment Station, shall not go unrecorded, the writer feels justified in .
