Brain MRI study did not reveal any abnormalities. Cerebrospinal fluid (CSF) collected from the cerebellomedullary cistern showed a marked increase of total nucleated cell count (400 cells/μL). Cytological evaluation identified the presence of a monomorphic round cell population characterized by large cell bodies, a single eccentrical located nucleus with high nuclear:cytoplasmatic ratio, and marked atypia with anisocytosis, anisokaryosis, and multiple nucleoli. Leptomeningeal carcinomatosis (LC) was suspected. The dog was euthanatized for worsening of clinical signs. Post-mortem examination identified an anaplastic mammary carcinoma in the nodular mammary mass. Infiltration by neoplastic cells exhibiting the same morphological features was detected along leptomeninges of the telencephalon and cerebellum associated with cortical and subcortical parenchymal micrometastases. To our knowledge, this is the first case of LC in a dog detected by CSF evaluation but without any MRI abnormalities. This finding emphasizes the usefulness of CSF cytology in patients with suspected LC even in the absence of any MRI identifiable lesions.","PeriodicalId":17185,"journal":{"name":"Journal of the American Animal Hospital Association","volume":"59 4","pages":"184-187"},"PeriodicalIF":1.3,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9817325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neurological examinations were consistent with left-sided lesions between spinal cord segments C1 and C5. Orthogonal radiographs of the cervical spine showed a microchip dorsoventrally oriented, partially embedded in the cervical vertebral canal. Fluoroscopy was used to localize and retrieve the foreign body from the cervical spinal cord in each case. Improvement in clinical condition and return to ambulation was observed in both cats within 48 hr of surgical removal of the implant. No significant perioperative adverse events were noted during the surgical retrieval of the microchip. Two previously reported cases of intraspinal canal microchip placement had been treated surgically by hemilaminectomy. This approach carries a risk of complications, including hemorrhage from the venous sinus, iatrogenic damage to the spinal cord, and improper identification of the surgical site, requires advanced surgical training, and typically has an extended surgical time. The use of fluoroscopy to assist intraoperative localization of a spinal canal foreign body may lessen the requirement for more invasive surgical procedures.","PeriodicalId":17185,"journal":{"name":"Journal of the American Animal Hospital Association","volume":"59 4","pages":"193-197"},"PeriodicalIF":1.3,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9811327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the indications for the use of TXA and EACA in cats and to describe dosing regimens used, occurrence of adverse events, and patient outcomes. This was a retrospective multicenter study. Medical databases were searched for feline patients billed for TXA or EACA between 2015 and 2021. Thirty-five cats met the inclusion criteria; 86% received TXA and 14% received EACA. The most common indication was nontraumatic hemorrhage (54%), followed by traumatic hemorrhage (17%) and elective surgery (11%). The median dose was 10 mg/kg for TXA and 50 mg/kg for EACA. Overall, 52% of cats survived to discharge. Potential adverse events were noted in 7/35 (20%) patients. Of these, 29% survived to discharge. No standardized dosing regimen was identified; rather, dose, dosing interval, and duration of administration varied markedly between patients. Administration was potentially associated with severe adverse events, although the retrospective design makes it difficult to establish a causal association with antifibrinolytic use.

Sedated thoracic radiographs revealed a luxated fifth intersternebral joint with the sixth sternebra being cranioventrally displaced (along with the seventh and eight sternebrae) to the level of the mid fourth sternebra. There were sharply marginated, short oblique fractures of the distal sixth costal cartilages bilaterally with mild dorsal displacement of the distal segment. The sternal luxation was palpated more aggressively once the patient was sedated and deemed to be stable. Because of the stability of the luxation and absence of sternebral fractures, conservative medical management in the form of analgesics and rest was instituted.

Consultation with a toxicologist revealed concern for manganese toxicosis resulting in hepatic injury. Both dogs developed subsequent acute liver injury, despite decontamination and initial management with N-acetylcysteine and cholestyramine. The patients were managed with calcium ethylenediaminetetraacetic acid, paraaminosalicylic acid, allopurinol, Vitamin E, ginkgo biloba, and S-adenosylmethionine/silybin. Liver values returned to normal in both dogs. Manganese exposure was confirmed with urine manganese analysis in one dog and fecal examination in the other dog.
