Esporotricose felina na região periocular - eficácia do tratamento com itraconazol / Feline sporotrichosis in the periocular region - successful treatment with itraconazole

Background: Sporotrichosis is a zoonotic disease caused by a dimorphic fungi of the Sporothrix schenckii complex. It isan emerging zoonosis with worldwide distribution, thus of great importance to public health. The infection occurs fromtraumatic inoculation of the fungus in the human skin from contaminated plants and soils and through bites or scratchesof infected animals. The occurrence of sporotrichosis has been related to zoonotic transmission, especially by domesticfelines. This work aims to report the successful use of itraconazole as monotherapy in a case of localized feline sporotrichosis and highlight the effectiveness of cytology in its diagnosis.Case: A 1-year-and-4-month-old spayed female cat undefined breed, weighing 3.1 kg, was referred to the VeterinaryMedical Teaching Hospital of the Universidade Estadual de Maringá (UEM), city of Umuarama, presenting a serosanguinous ulcerative lesion located in the left periocular region The clinical picture of the patient progressed over 3 months.Treatments with antibiotic therapy, corticosteroids, and surgical procedures were conducted, without clinical improvement. A new lesion in the distal portion of the thoracic limb emerged, proving that the disease remained in progression.Hematological exams were performed, among them hemogram, renal and hepatic biochemical analyses, SNAPS to identifythe feline immunodeficiency virus feline leukemia virus (FIV/FeLV), and cytology of the lesion through imprints. Thehematological results were all within the normal standards for the species. Cytology showed a large amount of oval andfusiform structures phagocyted by polymorphonuclear cells, free at the bottom of the slide, compatible with Sporothrixspp. The treatment administered was itraconazole (100 mg/cat), orally administered every 24 h, cefovecin sodium 8 mg/kg,subcutaneous, single dose, topical use of...

Agenesia renal unilateral em gatinha / Unilateral renal agenesis in kitten

Background: The kidneys are a pair of organs that maintain homeostasis, and perform hormonal and excretory functions; the functional unit of the kidney is the nephron. Approximately 2% of cats are born with some structural or functional anomaly, which occurs during fetal development. Unilateral renal agenesis is a rare congenital anomaly in felines, where the cat has only one kidney. This can lead to a series of dysfunctions, with clinical signs, especially when the contralateral organ does not adequately compensate, since there is more than one concomitant congenital disease like kidney dysplasia, which is the abnormal formation of the kidney structures. This study aimed to report the case of a kitten diagnosed with unilateral renal agenesis; the clinical signs, diagnosis, and treatment. Case: A 2-month-old mixed breed female kitten, weighing 0.5 kg, was attended in a veterinary clinic with emesis, hyporexia, hypodipsia, normuria, and diarrhea. Upon physical examination, dehydration, hyperthermia, and renomegaly by abdominal palpation were observed. Complementary examinations such as serum urea and creatinine estimation, abdominal ultrasound, and excretory urography, were requested, and the results include hemoglobin (9 g/dL), mean corpuscular volume (26%), normocytic normochromic anemia, urea (312 mg/dL), and creatinine (3.5 mg/dL). The abdominal ultrasound showed renomegaly on the left kidney and the absence of the right kidney. The above results and excretory urography help to confirm the diagnosis of unilateral renal agenesis and suggested renal dysplasia. The patient was hospitalized to stabilize her condition. The treatment is symptomatic and supportive and aims to increase the patient’s quality of life. Treatment with metoclopramide, erythropoietin, fluid therapy with ringer’s lactate solution, and renal therapeutic feed was prescribed. After 4 days of hospitalization and treatment, the serum creatinine was within normal...

Diagnostic accuracy of the electrocardiogram for detection of atrial and ventricular overloads in dogs

Background: Analysis of the electrocardiogram may suggest atrial and ventricular overloads. However, it has a lowsensitivity and specificity for diagnosis of cardiac chamber overload. The accuracy of electrocardiographic interpretation can be improve using new cut-offs for the duration and amplitude of the electrocardiographic waves. Ourobjective was to evaluate the use of the electrocardiogram in the diagnosis of atrial and ventricular overload, usingechocardiography as the gold standard test for the diagnosis of atrioventricular overload. We aimed to define newcut-off values that would increase the sensitivity and specificity of the electrocardiogram for diagnosis of chamberoverload in dogs.Materials, Methods & Results: Eletrocardiogram records were obtained in 81 dogs divided into 3 groups: Group1A (healthy dogs ≤ 10 kg); Group 1B (dogs ≤ 10 kg with mitral or tricuspid valve disease); Group 2 (dogs weighingbetween 10.1 and 20 kg) and Group 3 (dogs > 20.1 kg). Duration in milliseconds (ms) and amplitude in millivolts(mV) of P waves and QRS complexes, PR and QT segment, T wave amplitude and ST segment were evaluated in leadDII. Using leads I and III, the mean cardiac electrical axis in the frontal plane, expressed in degrees, was determinedas the mean of three consecutive measurements. Values considered normal in Group 1A and 1B for the durantion ofP wave was ≤ 45 ms and QRS duration ≤ 55 ms. In Group 2 the duration of P wave was ≤ 47 ms and QRS duration ≤61 ms. In Group 3 the duration of P wave was ≤ 50 ms and duration QRS ≤ 64 ms. These values (duration of P waveand QRS duration) were compared with echocardiographic measurements of the left atrium, considering the referencevalue AE/Ao ≤ 1.4 and measurements of the left ventricle in M-mode according to the body weight, respectively. AP wave amplitude ≤ 0.4 mV suggested that the right atrium size was normal and this was...(AU)
