Canine Hypothyroidism with Neurological Disorders
Background: Hypothyroidism is characterized by hypofunction of the thyroid gland. It results in deficient production of thyroid hormones. Neurological disorders resulting from hypothyroidism are rare, which highlights the importance of this study. This study reports a case of hypothyroidism in a dog with neurological clinical signs, that was treated at the Universidade Estadual de Santa Cruz’s Veterinary Hospital (HV-UESC).

Case: A 4-year-old male intact Dogo Argentino breed dog, weighing 64 kg, presenting obesity, anorexia, prostration, walking in circles, and chronic dermatopathy was presented at HV-UESC. Upon physical examination, the animal presented a deficit of proprioception in the 4 limbs, with preserved superficial and deep pain. No alteration was observed in the ears, that could explained the clinical signs. In terms of dermatopathy, the animal presented symmetrical alopecia in the lateral region of the thighs and tail. Blood samples were collected for a complete blood count and biochemical tests of urea, creatinine, ALT, AST and cholesterol. Imaging radiography and ultrasonography were performed, which ruled out thoracic and abdominal changes that could be related to the case. Prior to receiving the blood test results, idiopathic encephalitis was suspected and enrofloxacin and prednisone were prescribed for 7 days. During the medication period, previous exams were provided, which indicated only increased cholesterol (500 mg/dL). The animal showed no improvement with the prescribed medication. In view of the clinical signs presented by the patient and the results of the additional tests, hormonal disease was suspected, compatible with hypothyroidism. Thus, hormonal tests of total T4, free T4, and TSH were requested, leading to verification of reduced total T4 (0.3 ng/dL) and free T4 (0.15 ng/dL) levels, and confirming the dysfunction of the thyroid gland. The previous treatment was suspended and thyroid hormone replacement was initiated. After 3 days of treatment, the neurological signs regressed and the animal became more active; after 30 days, the areas of alopecia decreased. Although the patient did not receive the recommended clinical follow-up for such cases, it was possible to establish the ideal levothyroxine dosage for the dog after appropriate adjustments, which permitted thyroid hormone levels to return to normal.
Discussion: This report refers to a case of hypothyroidism in a giant dog breed. The dog in the report showed clinical signs of a dermatological, metabolic, and neurological nature, which is consistent with a lack of thyroid hormone. The main signs presented by the animal were neurological, such as walking in circles and a deficit of proprioception in the four limbs. These clinical signs are rarely mentioned in the literature associated with hypothyroidism. Laboratory abnormalities are correlated with the severity and chronicity of the disease. The animal showed a decrease in total T4 and free T4, which is to be expected in a hypothyroid animal. As a result, levothyroxine replacement treatment was initiated. The dose used for the dog, which is the recommended dose in the literature, greatly increased its total T4 levels. As a result, the dose was readjusted after a new clinical evaluation. The rate of metabolism and absorption of levothyroxine varies widely and is independent of weight. The patient showed quickly improvement in neurological signs, activity level, and serum cholesterol rate. Regarding dermatological signs and body condition, there was a more gradual improvement. This corroborates what is mentioned in the literature, which indicates that improvements can take many months.

Análises macro e microscópica de enxertos cutâneos por semeadura após laserterapia de baixa intensidade
Os enxertos de pele são uma alternativa para o fechamento de lesões extensas onde a reaproximação dos bordos da ferida não é possÃvel. A incorporação do enxerto no leito receptor depende de conexões arteriais e venosas dessas duas partes. Baseando-se em trabalhos em que a laserterapia de baixa intensidade acelera o processo de cicatrização e favorece angiogênese e, com intenção de se obter melhor resultado em enxertos cutâneos por semeadura, optou-se pela aplicação do laser HeNe. Dessa forma 20 ratos foram submetidos a esta técnica de enxertia e separados em dois grupos iguais, um tratado com laser e outro não (controle). Os resultados mostraram maior velocidade de cicatrização, menor tempo de reação inflamatória, maior número de vasos sanguÃneos, epitelização e queratinização precoces nos animais tratados com laser em relação aos não tratados, sugerindo então que a laserterapia de baixa intensidade é efetiva para o uso em enxertos por semeaduraSkin grafts are the alternative to close big lesions, when the borders approach are difficult or impossible. The graft incorporation on receptor site depends of blood vessels conection. Based on literature that low-level laser therapy acceletares the cicatricial process and favors the angiogenesis, HeNe laser was applied to accelerate the cicatricial process on island skin grafts. For this, 20 rats were submitted to this graft technique and divided in two groups with the same number of animals, one called laser and other called control. The results show faster cicatrization, short inflammatory period, larger number of blood vessels and precocious epitelization and queratinization on he laser group. These facts suggest that low-level laser therapy is effective and helps island skin grafts cicatrizatio

[Inability and neglect in ovarian-salpingohysterectomy of a bitch - Case report.] ImperÃcia e negligência em ovariosalpingohisterectomia de uma cadela - Relato de caso. Revista Brasileira de Medicina Veterinária, 36(4):425-429, 2014. Departamento de Ciências Agrárias e Ambientais, Universidade Estadual de Santa Cruz, Rodovia Jorge Amado, Km 16, Salobrinho, Ilhéus, BA 45662-900 Brasil. E-mail: [email protected] The veterinarian is error-prone in professional performance and is subject to punishment by the Board of Veterinary Medicine, establishing a series of penalties based on the Code of Ethics of the Veterinarian and vary according to the offense committed. Research shows that judicial conflicts involving clinic small animals tend to increase in major centers and in most situations, these conflicts include moral damages. The incompetence, recklessness and negligence are characterized as elements of guilt or the externalization of wrongful conduct and offenses arising from these elements are mainly causal, lack of information and knowledge of the professional offender. The objective of this report is to describe a case of recklessness and malpractice in a female Rotweiller sterilization surgery (ovary-salpingo-hysterectomy) and after a laparotomy performed at the Veterinary Hospital of the Universidade Estadual de Santa Cruz, was found an accidental ureter in a ligature and an abdominal cavity encapsulated foreign body

Efficacy of Preemptive Analgesia with Amantadine for Controlling Postoperative Pain in Cats Undergoing Ovariohysterectomy
This study aimed to evaluate the effect of the preemptive administration of amantadine on postoperative analgesia in cats undergoing ovariohysterectomy and its influence on the physiological parameters. Twenty healthy domestic cats scheduled to undergo ovariohysterectomy at the Santa Cruz State University, Ilhéus, were divided into two groups: the control group (Group C; n = 10) and the amantadine group (Group A; n = 10). The cats in Group C received placebo capsules 30 min prior to the standard anesthetic protocol, whereas those in Group A received 5 mg/kg of amantadine orally 30 min prior to the standard anesthetic protocol. Postoperative pain was assessed using the visual analog scale and the UNESP-Botucatu multidimensional scale for the evaluation of postoperative pain in cats. The administration of amantadine had no effect on the physiological parameters evaluated. The pain scores in Group A were lower than those in Group C, indicating that the frequency of rescue analgesic administration cats in Group A was lower. That way, preemptive oral administration of amantadine at a dose of 5 mg/kg was effective at controlling postoperative pain in cats undergoing ovariohysterectomy. Moreover, no adverse effects or alterations in the physiological patterns were observed in the treated animals
