“…Both methimazole and propylthiouracil (PTU) inhibit thyroid hormone production by inhibiting thyroid peroxidase. ‐Propylthiouracil is the most commonly used antithyroid medication in humans; however, adverse effects and limited studies prevent use in dogs 2,4,14 . Methimazole is routinely used to manage hyperthyroidism in cats and occasionally used in dogs 15 .…”

Key Clinical Message Thyroid storm is a rare, life‐threatening endocrine emergency that may occur in dogs. With rapid identification and early aggressive therapy, long‐term survival is possible. Abstract The aim of this paper was to describe the successful emergency management and long‐term survival of a dog with probable thyroid storm. We present proposed guidelines for the characterization of thyroid storm in dogs, and treatment considerations as utilized for this patient. A 6‐year‐old female spayed German Shepherd Dog was presented to a multispecialty center for radiation planning and treatment of a previously diagnosed nonresectable functional thyroid carcinoma. Recovering from anesthesia, the patient developed clinical features that would qualify as thyroid storm using human metrics. The patient improved with aggressive treatment of thyroid storm, extrapolating from human and feline recommendations. This is the first known report of long‐term survival in a canine with suspected thyroid storm. The crisis was effectively identified and emergently treated.

“…However, an article by Ward that does list clinical signs of feline thyroid storm 5 was published without peer review and the strength of the claims in this article were questioned by Peterson. 17 The papers that list criteria for thyroid storm in cats 5 12 focus on the conscious patient, and therefore must be interpreted with caution for this case. However, even when using these diagnostic criteria, our patient still would have been considered at risk of impending or current thyroid storm when presented to the hospital.…”

“…19 30 While a variety of triggers are postulated to explain elevations in free T 4 , it is not known if these occur in cats. 17 In any case, since the advent of antthyroid medications, the guidelines for human anaesthesia include that, where possible, a patient's thyrotoxicosis be controlled before surgery. 20 This is also recommended in the veterinary literature.…”

“…7 9 11 12 However, while thyroid storm is well recognised in human medicine, including during anaesthesia, [13][14][15][16] the progression and diagnosis of thyroid storm is less clear in feline medicine, indeed, some clinicians think the likelihood of true thyroid storm occurring in cats is minimal. 17 Thyroid storm has not yet been described in the veterinary literature, and thus the mortality rate is not known, nevertheless, it seems to be a recognised condition and diagnostic criteria have been published. 5 12 18 However, without any prior case reports or case series where the criteria have been used as a diagnostic instrument, its utility in identifying storm events must be exercised with restraint.…”

Suspected thyroid storm in a cat anaesthetised for bilateral thyroidectomy

A 14-year-old female neutered domestic short hair cat was referred for assessment of uncontrolled hyperthyroidism. The owners were advised that a bilateral thyroidectomy was required due to the presence of comorbidities that rendered radioiodine therapy inappropriate. During the procedure the cat exhibited unexpected extreme tachycardia, hypertension, hypercapnia, severe respiratory and metabolic acidosis and ventricular arrhythmias, which all resolved after removal of the thyroid glands. Recovery was complicated by the development of congestive heart failure and hypertension which were successfully managed and the cat was discharged five weeks after presentation. Thyroid storm was considered a possible explanation for the events that occurred during anaesthesia as well as the subsequent congestive heart failure and hypertension. Thyroid storm during anaesthesia has not been reported in animals. The similarities between the reported case and thyroid storm events in humans are discussed.

“…A icterícia foi citada por 3,77% dos participantes e embora não seja associada às manifestações primárias do hipertireoidismo em felinos, pode estar relacionada a complicações, como hepatopatia por efeito colateral ao uso de metimazol ou nas alterações hepáticas da "tireoid storm" (DAMINET et al, 2014, PETERSON, 2016 A azotemia pode ocorrer em 20 a 70% dos gatos hipertireoideos (PETERSON et al, 1983, MOONEY, 1996 que a presença doenças concomitantes afetam a indicação de qualquer modalidade terapêutica.…”

AGRADECIMENTOSMeus agradecimentos a todos que me ajudaram de alguma forma nessa trajetória. À minha mãe, pela paciência, pela amizade, por toda ajuda e principalmente por sempre acreditar no meu potencial. Muito mais do que eu mesma. Essa conquista também é sua.Ao Thomas, pelo companheirismo, amizade, amor, e por toda ajuda física e emocional que também foi crucial na execução deste trabalho. Além de não permitir que eu desista dos meus sonhos nos momentos mais difíceis. Aos animais; aos que tutelo e aos pacientes que me ensinam todos os dias sobre a arte de clinicar e a arte de amar. Ao Professor Dr. Archivaldo por tornar este sonho possível, por ser uma grande inspiração profissional (tanto clínico como acadêmico) desde a época de graduação. Por toda confiança depositada, pela orientação e paciência. Devo a ele todas as conquistas dentro da especialidade de felinos e da pós graduação. A todos os professores do curso, em especial aos do departamento de clínica médica. À professora Dra. Marcia Mery que também me traz grande inspiração como pesquisadora. Aos meus colegas de pós graduação pela parceria nas aulas e discussões clínicas. Com destaque à Marcela Pimenta que tanto me ajudou, na divulgação dos questionários e no momento final da confecção desta dissertação. E as grandes amigas Fernanda Chicharo e Pamela Backschat. Às veterinárias clínicas do HOVET, Bruna, Vera, Khadine, Denise e em especial à Andrea. Obrigada pela confiança, pelo conhecimento compartilhado e pela amizade. Ao Thom Y, pela inspiração. A CAPES pela ajuda financeira e a bolsa concedida. A todos os veterinários que dispuseram de seu tempo respondendo o questionário desta pesquisa. Sem dúvidas, este trabalho não seria possível sem a colaboração dos mesmos. E a todos aqueles que contribuíram de alguma forma, muito obrigada. "O conhecimento amplia a vida. Conhecer é viver uma arte que a realidade impede desfrutar." Carlos Bernardo Gonzàlez Pecotche RESUMO PADIN, B.R. Avaliação dos conhecimentos básicos de médicos veterinários brasileiros sobre o hipertireoidismo felino. [Evaluate the level of knowledge about hyperthyroidism in cats among the Brazilian veterinary community]. 2018. 105 f. Dissertação (Mestrado em Ciências) -Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, São Paulo, 2018. O hipertireoidismo é a endocrinopatia mais prevalente em felinos. Sua incidência vem aumentando nos últimos anos em todo mundo embora ainda seja pouco frequente no Brasil. Estudos evidenciam que gatos com manifestações clínicas da endocrinopatia têm baixa suspeição da doença pelos clínicos comparado a prevalência da mesma. Assim, este trabalho objetivou avaliar as opiniões e experiências de médicos veterinários brasileiros acerca da abordagem e manejo de felinos com hipertireoidismo por meio de um questionário com 22 perguntas sobre o tema. Foram respondidos 1113 questionários, onde 535 (48%) dos veterinários disseram realizar a palpação da tireoide em todos os gatos que atendem. Perda de peso (89,2%), hiperatividade (82,8%) e polifagia (...
