ABSTRACT
BACKGROUND: Hyperthyroid cats often have urine specific gravity (USG) values <1.035. It remains unclear how USG changes after treatment, if USG can be used to predict azotemia after treatment, or how iatrogenic hypothyroidism influences USG values. OBJECTIVES: To determine the proportion of hyperthyroid cats with USG <1.035 vs ≥1.035; if USG changes after treatment; and whether USG <1.035 correlated with unmasking of azotemia or hypothyroidism. ANIMALS: Six hundred fifty-five hyperthyroid cats treated with radioiodine; 190 clinically normal cats. METHODS: Prospective, before-and-after study. Hyperthyroid cats had serum thyroxine, thyroid-stimulating hormone, and creatinine concentrations, and USG measured before and 6 months after successful treatment with radioiodine. RESULTS: Of untreated hyperthyroid cats, USG was ≥1.035 in 346 (52.8%) and <1.035 in 309 (47.2%). After treatment, 279/346 (80.6%) maintained USG ≥1.035, whereas 67/346 (19.4%) became <1.035; 272/309 (88%) maintained USG <1.035, whereas 37/309 (12%) became ≥1.035. Only 22/346 (6.4%) with USG ≥1.035 developed azotemia after treatment, compared with 136/309 (44%) with <1.035 (P < .001). Of cats remaining nonazotemic, 38% had USG <1.035, compared with 20% of normal cats (P < .001). The 137 cats with iatrogenic hypothyroidism had lower USG after treatment than did 508 euthyroid cats (1.024 vs 1.035), but USGs did not change after levothyroxine supplementation. USG <1.035 had high sensitivity (86.1%) but moderate specificity (65.2%) in predicting azotemia after treatment. CONCLUSIONS AND CLINICAL IMPORTANCE: Hyperthyroidism appears not to affect USG in cats. However, cats with evidence of sub-optimal concentrating ability before radioiodine treatment (USG < 1.035) are more likely to develop azotemia and unmask previously occult chronic kidney disease. Iatrogenic hypothyroidism itself did not appear to affect USG values.

O aumento de animais domésticos tem se tornado constante e a forma mais eficaz para seu controle populacional é a castração. O tratamento de feridas cirúrgicas pode ser demorado ou ineficaz em pacientes com fatores predisponentes que desfavoreçam a cicatrização, como os idosos, diabéticos, obesos, desnutridos, e que apresentam processos infecciosos. Devido ao assunto, a busca por técnicas inovadoras e eficazes que favoreçam o processo cicatricial, impulsiona uma série de estudos científicos em todo o mundo. Diante disso pode-se utilizar a fitoterapia, a ciência na qual se proporciona o bem-estar animal e trata as enfermidades por meio das plantas medicinais, vem cada vez mais sendo usada, estimulando as defesas naturais do organismo do animal, tornando-se uma das melhores opções de tratamento não-agressivo. Assim neste trabalho foi utilizada a pomada manipulada à base de barbatimão nas porcentagens de 2,5% e 10% e placebo em gatas, para a cicatrização de ferida cirúrgica pós-operatório. Foram utilizadas no presente trabalho nove gatas hígidas, com a mesma média de idade, peso e escore corporal, divididas em três grupos com três gatas cada (G1, G2 e Grupo C). Todas as fêmeas passaram pelo procedimento de ovariohisterectomia. No pós-operatório, cada grupo recebeu um tipo de tratamento: o Grupo 1 foi tratado com pomada manipulada à base de barbatimão na concentração de 2,5%, enquanto o Grupo 02 fez uso da pomada manipulada na concentração 10% e o Grupo C recebeu a pomada de placebo.(AU)
The increase of domestic animals has become constant and the most effective way for its population control is castration. The treatment of surgical wounds can be lengthy or ineffective in patients with predisposing factors that disadvantage healing, such as the elderly, diabetic, obese, malnourished, and those with infectious processes. Due to the subject, the search for innovative and effective techniques that favor the healing process, propels a series of scientific studies around the world. Therefore, we can use herbal medicine, the science in which provides animal welfare and treat diseases through medicinal plants, is increasingly being used, stimulating the natural defenses of the animal's body, becoming one of the best non-aggressive treatment options. Thus, in this study will be used the barbatimão manipulated ointment in the percentages of 2.5% and 10% and placebo in cats, for postoperative surgical wound healing. Will be used in this study nine healthy cats, with the same average age, weight and body score, divided into three groups with three cats each (G01, G02 and Group C). All females will undergo the ovariohysterectomy procedure. In the postoperative period, each group will receive one type of treatment: Group 1 will be treated with barbatimão-manipulated ointment at a concentration of 2.5%, while Group 2 will use a manipulated ointment at a concentration of 10% and Group C received the placebo ointment.(AU)

Todas las hembras se sometieron a un procedimiento de ovariohisterectomía. En el postoperatorio, cada grupo recibió un tipo de tratamiento: el grupo 1 fue tratado con ungüento manipulado a base de barbatimão en una concentración de 2.5%, mientras que el grupo 2 usó el ungüento manipulado en concentración 10% y el grupo C recibió la pomada de placebo.(AU)

A 9-year-old, spayed female domestic shorthair cat presented for polyphagia, polydipsia, and polyuria following chronic methylprednisolone acetate therapy for pruritus. Initial diagnostics were consistent with uncomplicated diabetes mellitus. Serum calcium was within reference range. Within 12 hours the cat developed depression, anorexia, vomiting, and severe dehydration. Laboratory analysis indicated marked hypercalcemia as measured by both ionized and total calcium concentration. No underlying neoplastic or inflammatory process was identified. An adrenocorticotropic hormone stimulation test was indicative of adrenocortical insufficiency. The hypercalcemia resolved with glucocorticoid supplementation and correction of the dehydration. The diabetes mellitus and adrenal insufficiency both resolved within 9 weeks.

A 9-year-old Bedlington Terrier was evaluated because of weight loss, inappetence, and hematemesis. Copper storage disease had been diagnosed previously on the basis of high hepatic copper concentration. Treatment had included dietary copper restriction and administration of trientine for chelation of copper. A CBC revealed microcytic hypochromic anemia. High serum activities of liver enzymes, high bile acid concentrations, and low BUN and albumin concentrations were detected. Vomiting resolved temporarily with treatment, but the clinicopathologic abnormalities persisted. Results of transcolonic portal scintigraphy suggested an abnormal shunt fraction. Results of liver biopsy and copper quantification revealed glycogen accumulation and extremely low hepatic copper concentration. Serum and hair copper concentrations were also low. Chelation and dietary copper restriction were tapered and discontinued. Clinical signs and all clinicopathologic abnormalities improved during a period of several months.
