A 5‐month‐old colt sustained a mandibular degloving injury and penetrating cheek wound after catching his cheek on a metal hook. Avulsion of the lower left lip and cheek exposed parts of the underlying labial surface, interalveolar margin and body of the mandible. The injury prevented the colt from closing his mouth completely and food accumulated between the degloved mandible and avulsed soft tissues. Surgical repair included 7 stented, transmandibular mattress sutures placed over the length of the interalveolar margin, closing the dead space and repositioning the avulsed soft tissues. The horse recovered without complications and functional as well as cosmetic outcome were excellent. 相似文献

The case report presented here describes in detail the treatment and clinical progression of a case of severe chronic laminitis in a 10‐month‐old Arabian filly. Starting from the acute onset of clinical signs through the severe, debilitating progression of the disease, the report describes the medical, surgical and farriery treatment over a period of 8 months. The combination of deep digital flexor tendon tenotomy, hoof wall resection, corrective trimming and shoeing was successful in halting progression of the disease. The successful treatment resulted in new healthy hoof wall growth, re‐establishment of normal third phalanx‐hoof wall alignment and reversal of the degenerative modelling changes that occurred in the third phalanx. To the best of our knowledge, this is the first study describing treatment of severe chronic laminitis in such a young filly. 相似文献

Vertebral body osteomyelitis in the cervical spine secondary to Rhodococcus equi has been treated both medically and surgically. This Case Report describes a 4‐month‐old foal exhibiting severe neurological signs from R. equi vertebral body osteomyelitis. Rapid, significant resolvement of neurological signs was noted in this case with surgical debridement and use of synthetic bone filler. The outcome suggests that aggressive surgical therapy in conjunction with synthetic allograft may be indicated in treatment of cervical vertebral body osteomyelitis. 相似文献

A 3‐month‐old Quarter Horse filly presented with corneal ulceration in the right eye with extensive coalescing periocular ulcerations, erosions, and cutaneous crusts. Similar periocular lesions were present around the left eye, on the gingival mucosa, and on the cutaneous and mucosal surfaces of the lips. Based on the severity of the filly's corneal lesions, expense and duration of treatment, euthanasia was elected. Histological post mortem examination revealed numerous hyperplastic and/or dysplastic epithelial cells adjacent to areas of ulceration and erosion with intranuclear viral inclusion bodies. Equine herpesvirus‐3 (EHV‐3) was identified by polymerase chain reaction from the right cornea and lip. The virus was isolated from the right cornea, right eyelid and lip. The dam presented with multifocal to coalescing perineal vesicles. EHV‐3 was confirmed by polymerase chain reaction from the vulvar lesions and the mare recovered spontaneously. This is the first case of EHV‐3 corneal infection reported in horses and emphasises that EHV‐3 should be included as a differential diagnosis for vesicular lesions involving the equine periocular and oronasal epithelium. 相似文献

A 3‐month‐old female Basset Hound‐Shar Pei mix puppy (Ba‐Shar or Sharp Asset) presented with oral bleeding due to a cracked molar. On physical exam, an aural hematoma was also noted that the owner indicated was chronic. The puppy was hospitalized for over 24 h until the bleeding was brought under control. At 4 months of age, the puppy again presented with oral bleeding due to loss of deciduous teeth and was hospitalized until bleeding was controlled. Coagulation screening tests, platelet numbers, and von Willebrand Factor antigen levels were within reference limits. Based on the presence of platelet‐type bleeding in the face of normal screening test results, samples were submitted for DNA testing for Basset Hound thrombopathia. The puppy tested as affected for the calcium and diacylglycerol regulated guanine nucleotide exchange factor I (CalDAG‐GEFI) mutation causing this disorder. This is the first time thrombopathia has been diagnosed in a “designer” breed. 相似文献

A 9‐month‐old French Bulldog was presented with a chronic history of lateral strabismus and intermittent third eyelid protrusion in the left eye. The neuro‐ophthalmological examination revealed mild ptosis of the left upper eyelid, mild lateral strabismus, and external ophthalmoparesis of the left eye. Retraction and ventral deviation of the left eye globe with protrusion of the third eyelid and elevation of the upper eyelid were elicited on attempted voluntary adduction of the left eye. Hematology, serum biochemistry, serology for infectious diseases, magnetic resonance of the head, and cerebrospinal fluid analysis did not reveal significant abnormalities. Forced duction test did not show signs of mechanical restriction in ocular motility. A suspected congenital cranial dysinnervation disorder resembling Duane retraction syndrome in humans was diagnosed based on the typical clinical signs and exclusion of structural abnormalities. The clinical signs remained stable for 9 months until the time of writing this report. 相似文献

Follicular fluid (FF) accumulates in the antrum of the ovarian follicle. In addition, FF provides the microenvironment for oocyte development, oocyte maturation and competence, which are acquired during follicular development. Superstimulatory treatment of 1‐month‐old lambs can achieve synchronous development of numerous growing follicles. However, these growing follicles are unable to completely mature and ovulate. Furthermore, the oocytes exhibit lower competence compared with those of ewes. In this study, we utilized an isobaric tag for relative and absolute quantification (iTRAQ)‐based proteomics analysis and compare protein composition between pre‐pubertal and adult superstimulated follicle FF in sheep. In total, 243 differentially expressed proteins were identified, including 155 downregulated and 88 upregulated between lamb and ewe. Gene ontology (GO) and KEGG pathway analysis indicated that the differentially expressed proteins are involved in signal transduction, anatomical structure development, stress response, metabolic pathways, and the complement and coagulation cascades. Many of the proteins known to affect follicle development were observed in lower abundance in FF of lamb (e.g. ADAMTS9, CD14, CTNNB1, FST, GCLC, HSPG2, IGFBP2, IGFBP6, INHBA, PRL, PAPPA, POSTN, PRDX1, SERPINA1, SOD3, STC1, VEGFC, etc.). However, a higher abundance was observed for proteasome proteins. Inadequate amounts of these proteins in FF may be lead to the unique characteristics of follicular development in lamb. These differentially expressed proteins illuminate the age‐dependent changes in protein expression in the follicle microenvironment. 相似文献

The muscles of the infrapubic abdominal wall of crocodilians play an important role in their ventilatory mechanism. Yet the anatomy and homology of these muscles is poorly understood. To gain new insights into the anatomy of the crocodilian infrapubic abdominal wall, we dissected a specimen of Crocodylus niloticus. Origin and insertion of the muscles, as well as their arrangement relative to each other was examined in great detail. The findings were compared with those of other crocodilian taxa to detect potential variability of the muscles of interest. The homology of the muscles was studied by comparing the muscles of the crocodilian infrapubic abdominal wall with those of other diapsids. In Crocodylus niloticus, the infrapubic abdominal wall consists of four muscles: Musculus truncocaudalis, M. ischiotruncus, and Mm. rectus abdominis externus and internus. The arrangement of the muscles of the infrapubic abdominal wall of Crocodylus niloticus is consistent with that found in most other crocodilian taxa. In some crocodilian taxa, an additional muscle, M. ischiopubis, is found. In the remaining diapsids, only M. rectus abdominis is present. The crocodilian M. truncocaudalis, M. ischiotruncus and, if present, M. ischiopubis appear to be derivates of M. rectus abdominis; the development of those might be related to the evolution of the unique crocodilian ventilatory mechanism. 相似文献

Squamous cell carcinoma (SCC) is the second most common neoplasm reported in the horse, but occurs rarely in the oral cavity. Clinical signs may be insidious in onset and mimic other non‐neoplastic processes, thus delaying appropriate treatment. Timely evaluation and advanced diagnostic imaging may offer the opportunity to initiate definitive treatment. This report describes a young gelding with mandibular SCC that was evaluated for mandibular swelling failing to respond to symptomatic therapy. 相似文献

An 11‐month‐old Border collie presented collapsed and continued to deteriorate rapidly despite supportive treatment. The dog had a history of failure to thrive and recurring respiratory infection. Laboratory abnormalities included neutrophilic leucocytosis, Heinz body anaemia, hyperammonaemia, hyperbilirubinaemia, proteinuria and hypocobalaminaemia. Post‐mortem examination revealed multi‐focal necrosis within the heart, kidneys, pancreas, liver, meninges and cerebral cortex. Fungal hyphae in lesions were identified as Scedosporium prolificans following culture. Subsequent genotyping confirmed that the dog carried the CUBN:c.8392delC mutation in a homozygous state, verifying hereditary cobalamin deficiency (a.k.a. Imerslund‐Gräsbeck syndrome). Cobalamin deficiency may have been a predisposing factor for the development of systemic fungal infection in this dog. 相似文献

A 13‐year‐old Thoroughbred gelding was presented for evaluation of recurrent colic of 4 weeks duration. These colic episodes were mild and responsive to medical therapy. Episodes of colic became more frequent and more painful. Exploratory laparotomy revealed a large intestine duplication with a cystic structure located at the caecocolic junction that was unable to be exteriorized and therefore not amenable to surgical correction. Thirty‐six hours following surgery, the horse became acutely painful, sweaty, and febrile suggesting gastrointestinal rupture. Post mortem examination showed a 0.6 × 1 m duplication and a 0.5 × 0.6 m cystic dilation that was probably associated with the caecum. There was a 10 × 30 cm area of rupture located within the duplication. Histological evaluation confirmed the presence of a true duplication. 相似文献

This case report describes the identification of multiple soft tissue sarcomas in the pharyngeal region of a 5‐year‐old Quarter Horse mare. Diagnostic work‐up included physical examination, radiography, ultrasonography, endoscopic examination of upper airways and guttural pouch, and post mortem examination with histopathology. Humane euthanasia was indicated due to the chronicity of the condition, prognosis and financial constraints. 相似文献

Cerebellar abiotrophy (CA) is an uncommon neurological disease that most commonly affects Arabian horses. Affected horses are typically identified within the first 6 months of life. Intention tremor, wide based stance and ataxia are common clinical signs observed in affected individuals. No treatment is available for resolution of clinical signs. Definitive diagnosis is based on histopathological examination of cerebellar tissue, which is characterised by loss of Purkinje cell layer. This report describes a case of cerebellar abiotrophy that had a delayed diagnosis until 6 years of age. 相似文献

The crude testicular cells (CTCs) contain many cell types, such as Sertoli cells, leydig cells, spermatogonial stem cells (SSCs), spermatocytes, and other somatic testicular cells, that secrete various growth factors needed in spermatogenesis. The objective of this study was to characterize development of 5‐day‐old mice testicular cells cultured. Crude testicular cells prepared from the testes of 5‐day‐old male mice were cultured in Dulbecco's Modified Eagle Medium and incubated at 37°C in a 5% CO2 atmosphere for 6 days. The results demonstrated that the testicular cells developed rapidly with a population doubling time (PDT) of 0.63 days and more than 90% of cells were viable after being cultured for 3 days. The number of Sertoli‐like cells increased significantly over days 1, 3, and 6 to 22.1%, 34.6%, and 50.1%, respectively. A significant increase was also observed in fibroblast‐like cells (15.5% on day 1 to 28.8% on day 3 and to 26.6% on day 6). In contrast, the number of spermatogonia‐like cells decreased significantly (54.3%, 30.4%, and 18.7%, on days 1, 3, and 6, respectively). These data indicated that the developmental pattern of the testicular cell in this study might be affected by the niche provided by the cultured testicular cells. 相似文献

This article reports the successful management of a 2‐year‐old Thoroughbred filly that presented with clinical signs of hypertrophic osteopathy, diffuse granulomatous dermatitis, lethargy and inappetence. An infectious primary focus was suspected due to an elevated white blood cell count (WBC), marked neutrophilia and dramatically increased serum amyloid A (SAA) and plasma fibrinogen levels. After failure to respond to a range of antimicrobial treatments, an actinomycetes bacterial infection, such as Mycobacterium avium or Rhodococcus equi, was suspected and the horse was started on rifampicin and clarithromycin treatment, which resulted in a rapid and pronounced improvement in clinical signs. After 10 weeks of treatment the skeletal manifestations had regressed, both clinically and radiographically, in addition to normalisation of the WBC count, SAA and fibrinogen levels. 相似文献
