A 13-year-old female domestic shorthair cat was examined because of weight loss over 4 months. The history included being neutered when a kitten and no signs of estrus recognized by the owner since this surgery. A mid-abdominal mass was palpated. Ultrasonographic abdominal evaluation revealed a tubular fluid-filled mass. The cat underwent surgery to remove the mass, which was one horn of the uterus. The patient made a full recovery.
This report describes a 14-year-old neutered male Norwegian Forest cat that was evaluated for a complaint of inappetence, lethargy, and ocular protrusion with third eyelid prolapse. The systemic blood pressure was elevated at 205/129 mmHg. Fundic examination revealed severe retinal hemorrhage in both eyes. Based on an ultrasound study of the retrobulbar area, a thrombus caudal to the right globe was suspected. Over 18 days, the cat exhibited significant clinical improvement as well as good blood pressure control. To our knowledge this is the first report of a retrobulbar thrombus in a cat with systemic hypertension.
We report evidence of intragraft lymphocyte activation in the early days of FSGS recurrence. Aspiration biopsy cultures showed failure of cyclosporin A to inhibit interleukin-2 (IL-2) production by infiltrating lymphocytes. If our findings are confirmed in similar patients, a trial with anti-IL-2-receptor antibody could be warranted.
Pesq. Vet. Bras. 33(1):80-85, janeiro 2013 80 RESUMO.-O hipertireoidismo é a endocrinopatia mais comum em gatos idosos. Devido à natureza progressiva da doença, a identificação de um estágio subclínico se torna Avaliação do perfil clínico e laboratorial de gatos hipertireoideos com ou sem lobo tireoidiano aumentado a palpação cervical Hyperthyroidism is the most common endocrine disorder of older cats. Due to the progressive nature of the disease, the identification of a subclinical stage is essential in order to have a better control of the disease. The present study was a survey of the frequency of feline hyperthyroidism in Rio de Janeiro, from March, 2007 to April, 2008. The purpose of this study was to perform an evaluation of the clinical, laboratorial and echocardiographic aspects in a feline population of naturally acquired hyperthyroidism, with or without palpable thyroid gland. The selection of the cats was done by the documentation of an elevation of total thyroxine (TT4) levels by radioimmunoassay. The animals were divided in two groups according to the thyroid palpation: group I (non-palpable thyroid lobe) and group II (palpable thyroid lobe). Laboratorial and complete clinical evaluations were performed in all cats. The clinical evaluation included behavioral evaluation, body weight, body condition, dermatologic, cardiopulmonary auscultation, thyroid palpation and systolic blood pressure reading. Besides the TT4, the following exams were performed: urea, creatinine, alanine aminotransferase (ALT), alkaline phosphatase (ALP) and glucose. Thirty one cats had an echocardiogram performed. On the basis of TT4 concentrations, 51 of the 178 cats were classified as hyperthyroid. One or more enlarged thyroid glands were palpated in 25 of the 51 hyperthyroid cats and were included at Group II. Twenty six cats didn't palpable thyroid gland and were included at Group I. Clinical, laboratorial and echocardiographic parameters were similar between the two groups. However, the TT4 levels were significantly lower in the non-palpable thyroid group. All geriatric cats must be thyroid gland palpable on clinic examination and have TT4 measured. Many hyperthyroid cats may be asymptomatic and early diagnosis prevents organ damage such as liver, kidneys and heart.
