Diarrhea has a multifactorial etiology and is one of the main diseases affecting dairy calves, promoting high mortality rates in the first weeks of life. This study aimed to assess diarrhea incidence and clinical aspects, as well as clinical responses to treatment (oral and intravenous) with electrolyte solutions. A total of 40 crossbred newborn calves were subjected to daily physical examination until 25 days. Calves with diarrhea (score 3) and dehydration (8% to 10%) received electrolyte replacement therapy orally or intravenously, according to estimated fluid loss, as well as a maintenance volume (oral). Blood and urine samples were collected between 16 and 24 hours after birth and at 5, 10, 15, 20, and 25 days; in diarrheic animals, these materials were collected immediately after the identification of diarrhea and at 2, 12, 24, and 48 hours after treatment initiation. Globular Volume (GV) and Total Plasma Proteins (TPP) were evaluated, in addition to physicochemical urine characteristics. Failures in the transfer of passive immunity may have contributed to the occurrence of diarrhea in 30 calves (75%), which maintained good body condition with no complications. Urine analysis showed a higher pH in non-diarrheic calves (6.7) compared to diarrheic calves (6.2) (p=0.0029), indicating acidification; higher GV, TPP, and urine density were found for diarrheic calves, with reductions 2 hours after hydration and slight variations up to 48 hours, indicating the effectiveness of hydration and acidosis correction.

Subclinical ketosis (SCK) is one of the main metabolic diseases to occur during the transition period in dairy herds. The aim of this study was to evaluate the localized incidence of SCK in dairy cows in the semi-arid region of the state of Paraíba, Brazil, and to correlate this data with the number of weeks of lactation and the body condition score (BCS). Samples were collected from the coccygeal vein of 257 lactating dairy cows, with a view to determining serum ketone and glucose body levels. Animals that presented serum ketone body levels equal to or greater than 1.2 mmol/dL were considered to have SCK. It was found that 5.45% of the dairy cows presented SCK. The weeks of lactation and the BCS had no influence (P > 0.05) on the levels of serum ketone bodies or glucose of the dairy cows. For serum ketone body levels, 94.55% (243) of the cows remained within the normal limits for metabolites. Most of the cows, 67.70% (174) were within normal serum glucose levels, while 23.35% (60) presented hypoglycaemia, and 8.95% (23) presented hyperglycaemia. The BCS and serum glucose levels are negatively correlated, with a coefficient of -0.1329 (P = 0.0335). No significance was found 0.087 (P = 0.1608) for the correlation between the BCS and serum ketone body levels. The localized incidence of SCK in this study was 5.45% of the total number of cows, with the BCS and number of weeks of lactation having no influence on incidence of the disorder.

Eyelid agenesis, also known as palpebral coloboma, is the most frequent congenital abnormality of feline´s eyelid compromising the patient's ocular health. The treatment of choice is blepharoplasty, which can be performed using different surgical techniques, depending on the extent of the coloboma. This paper reports a feline case diagnosed with coloboma in approximately 50% of the temporal and bilateral upper eyelid, which was treated using the Roberts-Bistner technique. Attention to the primary surgical care and delicate manipulation of tissues allowed maximum use of the wholly healed flaps. Trichiasis is a common complication inherent to traditional coloboma correction techniques and despite this was observed in both eyes a few weeks after surgery, the, reconstructive blepharoplasty provided adequate eyelid function and good cosmesis for the correction of eyelid agenesis in this patient.

This study describes the findings of the clinical and anatomopathological diagnosis in cattle affected by perforated abomasal ulcers and with comorbidities. Twenty-five cattle were evaluated, young (n=8, aged less than two years) and adults (n=17, aged greater than two and a half years), diagnosed with perforated abomasal ulcers. Epidemiological information was retrieved from the medical records. Blood, ruminal fluid, and peritoneal fluid (PI) samples were collected for laboratory examination. Ultrasound examination, exploratory laparotomy, and post mortem examinations were performed for diagnostic purposes. The main clinical findings of perforated ulcers in the present study were: apathy, dehydration, intestinal hypomotility, diarrheal stools, hypomotile or atonic rumen, tachycardia, tachypnea, abdominal distention with bilateral bulging, and increased abdominal tension. The most frequent abnormal hematological findings were hypoproteinemia and neutrophilic leukocytosis with a left shift. The peritoneal fluid (PL) showed an inflammatory reaction in the cytology, characteristic of an exudate. A confirmatory diagnosis of peritonitis by ultrasonography was possible in five cases, and in two cases at exploratory laparotomy. In the post mortem examination, the ulcers were characterized as type 3, 4, or 5, with comorbidities present in 68% of the cases. It is necessary to combine ultrasonography with abdominal centesis and exploratory laparotomy procedures to suggest perforated ulcers. However, post mortem examination better characterizes the type of perforated ulcer present, particularly type 5.

The objective of this work was to analyze the cases of otitis in companion animals treated at the Veterinary Hospital Jeremias Pereira da Silva / Universidade Federal do Piauí (UFPI) and the profile of antimicrobial drugs used in the treatment of these infections. A retrospective cross-sectional observational epidemiological study was carried out on the assisted animals with otitis at the Veterinary Hospital Jeremias Pereira da Silva / (UFPI), during the period from January 2015 to December 2020, through access to the registration system called “Doctorvet”, evaluating the characteristics of the patients treated, the diagnosis and therapy adopted and the clinical response to these services. Mixed breed dogs (MBDs), with bilateral presentation of this disease and the presence of comorbidities were frequent occurrences in the animals treated. Antibiotic prescriptions of aminoglycosides (Gentamicin and Neomycin) were the most used, in formulations associated with other substances, such as antifungals and anti-inflammatories, with the commercial presentation Aurivet being the most prescribed and the one that received the greatest number of favorable reports. However, the use of other different therapeutic protocols was evidenced without justification for this choice. Establishing therapeutic protocols to be followed by veterinary clinicians, when treating otitis, and monitoring the success or failure of these prescriptions, will contribute to reveal much more than the epidemiological profile of the etiologic agents, but the adequate use of antimicrobial agents, controlling the increase in rates of antibiotic resistance, as well as consolidating promising therapeutic approaches for these infections.
这项工作的目的是分析在皮奥伊联邦大学（Universidade Federal do Piauí，UFPI）杰雷米亚斯-佩雷拉-达席尔瓦兽医院（Jeremias Pereira da Silva / Veterinary Hospital Jeremias Pereira da Silva）接受治疗的伴侣动物耳炎病例以及用于治疗这些感染的抗菌药物的概况。通过访问名为 "Doctorvet "的登记系统，对2015年1月至2020年12月期间在杰雷米亚斯-佩雷拉-达席尔瓦兽医院（UFPI）接受过耳炎辅助治疗的动物进行了一项回顾性横断面流行病学观察研究，评估了接受治疗的患者特征、采用的诊断和疗法以及对这些服务的临床反应。在接受治疗的动物中，混种犬（MBD）经常出现双侧发病和合并症。氨基糖苷类抗生素（庆大霉素和新霉素）是最常用的抗生素，与其他药物（如抗真菌药和消炎药）一起配伍使用，其中商业化的 Aurivet 是最常用的抗生素，也是获得最多好评的抗生素。不过，也有使用其他不同治疗方案的证据，但都没有说明这样做的理由。制定兽医临床医生在治疗中耳炎时应遵循的治疗方案，并监测这些处方的成败，将有助于揭示的不仅仅是病原体的流行病学概况，还有抗菌剂的充分使用、控制抗生素耐药性的增加，以及巩固对这些感染有前景的治疗方法。

Tegumentary mycobacteriosis in cats is not very common. Three manifestations of skin disease associated with mycobacteria are recognized in domestic cats: feline leprosy, cutaneous tuberculosis and atypical mycobacteriosis. This study aims to describe a case of feline pyogranulomatous panniculitis associated with Mycobacterium spp., diagnosed through histopathology and histochemistry. The case occurred in a domestic feline, three years old, five kg, male, of mixed breed, which, in the clinical-physical exam, presented multiple subcutaneous nodules without ulceration of the epidermis and of firm-elastic consistency in the axillary and pectoral regions. One of the axillary nodules was surgically removed, placed in 10% formalin and sent for anatomopathological examination. Histologically, severe, sometimes multifocal, marked focally extensive pyogranulomatous dermatitis and panniculitis were revealed. Amid pyogranulomatous panniculitis, there was the formation of extracellular lipid vacuoles, also called lipocysts, surrounded by numerous neutrophils and histiocytes and with a lumen displaying eosinophilic amorphous material with a granular appearance. Histological sections were submitted to special Ziehl-Neelsen staining to detect alcohol-acid-resistant bacillus (BAAR), revealing multiple extra and intra-histiocytic mycobacteria inside the lipocysts. Thus, the anatomopathological and histochemical findings found in the feline indicated that this was the first case of pyogranulomatous dermatitis and panniculitis associated with Mycobacterium spp. reported in southern Brazil.

This is the first report of equine nasal rhinosporidiosis in Mineiros, Goiás, diagnosed through the histopathological analysis of granulomatous masses removed from a horse’s nostril of a 12-year-old male horse, through a surgical procedure. Microscopy revealed a papillomatous tissue lesion covered by moderately hyperplastic squamous epithelium, rich, loose fibrocollagenous tissues, well vascularized, accompanied by an accentuated inflammatory reaction constituted by a mixture of macrophages, lymphocytes, plasmocytes, and smaller number of neutrophils, and numerous round to oval structures with a unilamellar wall and a central nucleus surrounded by basophilic granular material, which were morphologically compatible with Rhinosporidium spp. sporangia.

Long bone fractures are common in juvenile cattle, however, cases of fractures occurring in the intrauterine environment during pregnancy are rare. The objective of this report is to present a case of an open consolidated fracture of the metacarpal that occurred in uterus, in a newborn calf, in which the surgical approach used was successful. A 48-hour-old female bovine was treated at the Veterinary Hospital of Paranaense University, who presented a complete, open and poorly consolidated transverse diaphyseal fracture in uterus during the gestational period on clinical and radiographic examination. As a therapeutic approach, open reduction was chosen, with ostectomy followed by stabilization with type IA external skeletal fixator. Four 4mm transcortical pins were positioned proximally and distally to the newly formed fracture line, followed by two more pins in the proximal phalanges region, seeking to stabilize the metacarpophalangeal joint, since flexural deformity of that joint was observed after the realignment of the longitudinal axis of the metacarpal, even after the section of the superficial and deep digital flexor tendons and suspensory ligament. The ESF was removed after 32 days, when radiographic signs of neoproliferation and bone consolidation were observed. In a last evaluation 15 months after the surgical correction, a complete and satisfactory recovery was observed regarding the development and well-being of the animal.

In a last evaluation 15 months after the surgical correction, a complete and satisfactory recovery was observed regarding the development and well-being of the animal.","PeriodicalId":38626,"journal":{"name":"Acta Veterinaria Brasilica","volume":"40 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139603288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to describe the macroscopic and histological lesions observed in domestic newborn felines with facial lesions characterized by holoprosencephaly associated with synophthalmia and arhinia. A feline with multiple craniofacial congenital anomalies was necropsied, and the brain was collected, followed by photodocumentation and histopathological processing with H&E. The diagnosis of alobar holoprosencephaly with grade (I) morphological lesions of the face was made through the anatomopathological changes observed during the clinical and necroscopic examination, characterized by deformation of the cerebral hemispheres, shown failure in the forebrain vesicle development, located in the cranial neural tube part, associated with craniofacial dysmorphisms. In the microscopic study of the CNS, lesions characterized by abnormal lamination of the cerebral hemisphere's outermost cell layers and multiple areas of vacuolization of the cortex and in the cerebellum low cell density of the granular layer, with the presence of large intracytoplasmic vacuoles and absence of Purkinje cells were observed. It was not possible to determine the deformation cause, since laboratory tests were not performed, as well as the association with the FeLV virus.

Complementary tests are essential for defining the diagnosis, prognosis, and treatment of diseases in animals. White blood count is the most common laboratory method for identifying and evaluating inflammatory processes in small animals. Therefore, this study aimed to evaluate plasma fibrinogen and C-reactive protein as supplementary tools for diagnosing inflammatory processes in dogs, correlating them with the results of the white blood count and the clinical condition of the animal. The sample size was calculated considering the estimated population of dogs living in the rural area of Curuçá, PA, Brazil. The sample included randomly selected healthy and unhealthy dogs. The animals underwent a clinical examination and complete blood count, fibrinogen, and C-reactive protein tests. Of a total of 149 animals, 17.4% (26/149) had hyperfibrinogenemia, 39.6% (59/149) were C-reactive protein positive, and 48.3% (72/149) had leukocytosis. Of the cases of leukocytosis, 63.8% (46/72) were due to neutrophilia. The analysis of the plasma protein: fibrinogen ratio in animals with hyperfibrinogenemia showed that the increased results were related to inflammatory processes in 84.6% (22/26) of these dogs. The results showed that fibrinogen and C-reactive protein are promising tools to identify inflammatory processes in dogs even before the presence of clinical signs; therefore, they are considered supplementary routine care methods to detect recent inflammatory processes not yet identified in the white blood count.
辅助检查对确定动物疾病的诊断、预后和治疗至关重要。白细胞计数是确定和评估小动物炎症过程最常用的实验室方法。因此，本研究旨在评估血浆纤维蛋白原和 C 反应蛋白作为诊断犬炎症过程的辅助工具，并将其与白细胞计数结果和动物的临床状况联系起来。样本量是根据生活在巴西宾夕法尼亚州库鲁卡农村地区的狗的估计数量计算得出的。样本包括随机挑选的健康和不健康的狗。这些动物接受了临床检查和全血细胞计数、纤维蛋白原和 C 反应蛋白检测。在总共 149 只动物中，17.4%（26/149）患有高纤维蛋白原血症，39.6%（59/149）C 反应蛋白呈阳性，48.3%（72/149）患有白细胞增多症。在白细胞增多的病例中，63.8%（46/72）是由中性粒细胞增多引起的。对高纤维蛋白原血症动物血浆蛋白：纤维蛋白原比率的分析表明，84.6%（22/26）的狗血浆蛋白：纤维蛋白原比率升高与炎症过程有关。结果表明，纤维蛋白原和 C 反应蛋白是一种很有前途的工具，甚至在出现临床症状之前就能识别犬的炎症过程；因此，它们被认为是检测白细胞计数尚未识别的近期炎症过程的辅助常规护理方法。
