The purpose of this study was to investigate the epidemiology, pattern of injury and management of facial dog bite injuries. Methods: The authors conducted a retrospective cohort study over a 5-year period of patients who sustained a facial dog bite injury. The study setting was an Oral and Maxillofacial Surgery Department at a level 1 trauma centre, servicing an estimated catchment population in excess of 950,000 people. Results: In total, 171 patients were managed in the designated period from January 2017 to January 2022...

In late December 1973, the United States enacted what some would come to call "the pitbull of environmental laws." In the 50 years since, the formidable regulatory teeth of the Endangered Species Act (ESA) have been credited with considerable successes, obliging agencies to draw upon the best available science to protect species and habitats. Yet human pressures continue to push the planet toward extinctions on a massive scale. With that prospect looming, and with scientific understanding ever changing, Science invited experts to discuss how the ESA has evolved and what its future might hold...

BACKGROUND: Veterinarians hold distinct breed-specific pain sensitivity beliefs that differ from the general public but are highly consistent with one another. This is remarkable as there is no current scientific evidence for biological differences in pain sensitivity across dog breeds. Therefore, the present study evaluated whether pain sensitivity thresholds differ across a set of dog breeds and, if so, whether veterinarians' pain sensitivity ratings explain these differences or whether these ratings are attributed to behavioral characteristics...

Dextrocardia with situs solitus is a rare disorder caused by embryological malformation. It may be asymptomatic and overlooked when isolated, or when it presents with different symptoms and clinical signs associated with other cardiac and extracardiac malformations. The present article describes the radiologic, electrocardiographic, and echocardiographic findings of a Pitbull dog with isolated dextrocardia and situs solitus .

A 15-month-old intact female Pitbull was referred because of recurrent, episodic, self-limiting, excitement-induced bleeding from nontraumatised skin. No abnormalities were detected upon physical examination. Subsequently, the dog went for a walk under the direct supervision of one of the authors, became overexcited and, after approximately five minutes, bloody liquid, with a patchy distribution, appeared along the hair shafts of the face and neck. The affected skin was congested, partially blanching on diascopy and bloody liquid was oozing from the follicular openings...

A 9-year-old castrated male pitbull dog was presented for evaluation of a subconjunctival swelling of 10 days duration. On ophthalmic examination, a subcutaneous mass was identified at the right lateral canthus. An excisional biopsy was performed, and histopathological analysis confirmed a diagnosis of a subcutaneous fibroma. Eleven months after surgical excision, the dog had no evidence of recurrence. Fibroma should be included in the differential diagnosis of rapidly enlarging eyelid masses.

BACKGROUND: Onchocerca lupi is an emerging, zoonotic filarioid nematode associated with ocular disease in companion animals in North America and the Old World. The areas where this parasite is assumed to be endemic in the USA comprise southwestern states. Thus far, all cases reported outside of the southwest are associated with travel or animal movement. METHODS: An 11-year-old, castrated male Pitbull dog from McAllen, Hidalgo County, southern Texas, with no travel history, was diagnosed with a perforating corneal ulceration of the right eye...

Electroporation is a technique that increases the uptake of chemotherapeutic drugs by tumors. Electrochemotherapy (ECT) has been successfully used to treat solid tumors. Recently, novel applications have been explored in the treatment of visceral tumors. This report aimed to describe the ECT as an approach to vesical carcinoma in three dogs. The patients received ECT with bleomycin as an intravenous bolus and intra-lesional cisplatin (cases 2 and 3). The ECT was performed by electroporator (Onkodisruptor® ) using a plate and/or a single pair needle array electrode...

OBJECTIVE: The aim of this study was to identify risk factors associated with facial dog bites and discuss prevention strategies. STUDY DESIGN: This is a retrospective analysis of facial dog bites treated at the Massachusetts General Hospital (MGH) from 1997to 2018. Patients were identified through the Research Patient Data Registry. The predictor variables included demographic characteristics, circumstantial information regarding the injury, and dog characteristics...

Canine congenital malformations are structural or functional abnormalities of organs present at birth that possibly interfere with the viability of newborns, thus contributing to neonatal mortality. This study evaluated and described the incidence of congenital malformations in neonatal dogs and determined the mortality rates among those affected. Of the 178 litters and 803 newborns included in the study, 24.7% (44/178) of the litters presented neonates with congenital malformations. The total rate of neonates that presented malformations was 6...

OBJECTIVES: To investigate the capacity of a trained dog to identify LC in patients with malignant SPN. METHODS: We collected 90 exhaled gas samples from 30 patients with SPN (3 samples/patient). As controls we used 61 healthy volunteers and 18 COPD patients without SNP or LC, in each of whom we collected 5 exhaled gas samples (n = 395). The dog (Blat, a 4-year-old crossbreed between a Labrador Retriever and a Pitbull) and the methodology used were the same as previously reported by our group (see: https://drive...

Haemangiosarcoma (HSA) is a malignant tumour of vascular endothelial cells. It is common in dogs, but rare in other species, and may arise in any tissue. A dermal location of canine HSA has been associated with short survival and recurrence after surgical excision. Solar radiation has been proposed as a predisposing factor in shorthaired dogs with light skin pigmentation. There are no studies relating the expression of immunohistochemical markers to survival of dogs with cutaneous haemangiosarcoma (cHSA). Such data could contribute to establishing prognostic factors and new therapies based on the expression of target molecules...

INTRODUCTION: Dog bite injuries to the face are a serious, yet modifiable public health concern. This study explores the relationship between dog breed and the risk of biting and injury. The objective of this study is to determine the relative risk and severity of dog bite injuries to the face by breed. METHODS: Retrospective chart review of facial dog bite injuries presenting to the University of Virginia Health System and Nationwide Children's Hospital. Additionally, descriptive data was collected from 240 patients over the last 15 years...

Facial fractures due to dog attacks have an unknown incidence rate. To date, only 41 cases of canine bite trauma in a pediatric patient, associated with facial fracture, have been reported in the literature. As major species of involving dogs are the American pitbull terrier and rottweiler. Due to the intense kinematics of this trauma, the treatment becomes complex. Thus, attention to the primary repair of such complex lesions ensures satisfactory results, which is the focus of this discussion. The purpose of this review was to analyze how different ways to approach this type of trauma in children for clarification or correct management...

A 14-month-old female pitbull terrier mix was presented for evaluation of dysphagia of 8 months' duration secondary to intermittent dorsiflexion of the tongue apex. Physical and neurological examinations were unremarkable with the exception of the dorsiflexed tongue. Serum creatine kinase activity was increased (703 IU/L, reference interval: 55 to 257 IU/L), and electromyography of the tongue demonstrated areas of fibrillation potentials. Histopathology of the tongue showed myopathic changes with excessive variability in myofibre size and endomysial fibrosis...

OBJECTIVES: Early lung cancer (LC) diagnosis is key to improve prognosis. We explored here the diagnostic performance of a trained dog to discriminate exhaled gas samples obtained from patients with and patients without LC and healthy controls. METHODS: After appropriate training, we exposed the dog (a 3-year-old cross-breed between a Labrador Retriever and a Pitbull) to 390 samples of exhaled gas collected from 113 individuals (85 patients with LC and 28 controls, which included 11 patients without LC and 17 healthy individuals) for a total of 785 times...

OBJECTIVE: To provide an overview of the epidemiology of canine multicentric lymphoma in Germany. MATERIAL AND METHODS: A total of 411 dogs with multicentric malignant lymphoma were retrospectively analysed regarding breed, age, sex, weight and the number of animals dogs with hypercalcaemic lymphoma and B-/T-immunophenotype, and compared to two reference populations (total own clinic population, n   =   52  142; dogs with health insurance in Germany, n   =   123  423)...

BACKGROUND: Cranial cruciate ligament rupture (CCLR) is one of the most important stifle injuries and a common cause of lameness in dogs. Our objective was to measure the vertical forces in the pads of Pitbulls with cranial cruciate ligament rupture (CCLR) using a pressure sensitive walkway. A pressure sensitive walkway was used to collect vertical force data from the pads of 10 Pitbulls affected with unilateral CCLR. Ten healthy Pitbulls were included in the study as controls. Velocity varied between 1...

This work aimed at giving a deeper insight into peculiar cases of intersexuality occurring in dogs and known as XX true hermaphrodism due to the existence of both testicular and ovarian tissue in one or both gonads in the presence of an XX chromosome constitution. Clinical, histological and genetic approaches were used in the study of an 8-month-old Cocker Spaniel dog and a 3-year-old mixed-breed Pitbull, both showing a female phenotype, clitoromegaly and male behavior. A normal female karyotype (2n = 78,XX) was noticed, and polymerase chain reaction failed to detect SRY in genomic DNA obtained from peripheral blood lymphocytes of both dogs...

The expertise on the interpretation of and 11 b TierSchG assumes that a hypertrophy of aggressive behaviour exists in some blood lines of Bull Terriers, American Staffordshire Terriers and Pitbull type dogs. This study was carried out to detect whether a hypertrophy of aggressive behaviour occurred in a certain Bull Terrier breed line. A total of 38 dogs representing this line were tested according to the guidelines of the Dangerous Animals Act of Lower Saxony, Germany (GefTVO) enacted on July 5th, 2000. Furthermore, the results of their behaviour towards other dogs during the test were compared to those of 347 dogs tested by Böttjer (2003) in order to investigate possible significant differences in the occurrence of inadequate or disturbed aggressive behaviour...
