Rânula bilateral com recidiva em glândula mandibular e sublingual em cão / Ranula bilateral with recurrence in submandibular gland and sublingualin dog

A mucocele sublingual é uma afecção incomum em cães, porém de grande importância para a medicina veterinária, devido aosprejuízos gerados por suas consequências. Deste modo, o presente relato tem como objetivo descrever o caso de mucocelesublingual em cão com posterior recidiva em glândula mandibular e sublingual, bem como discutir sua importância para a medicinaveterinária. Foi atendido no Hospital Veterinário Dix-Huit Rosado Maia HOVET/ Universidade Federal Rural de Semiárido(UFERSA), um cão macho, com um ano e 10 meses de idade, apresentando aumento de volume bilateral na região sublingualhá, aproximadamente, dois meses. Após exame clínico suspeitou-se de mucocele da glândula sublingual bilateral (rânula)indicando-se o tratamento de ressecção da glândula sublingual esquerda devido ao aspecto nodular e marsupalização da glândulasublingual direita. Passado um mês da alta médica o animal retornou ao HOVET UFERSA com queixa de aparecimento de umnovo aumento de volume sublingual e na região cervico-ventral suspeitando-se de uma possível mucocele cervical e recidivada mucocele sublingual esquerda. Indicou-se como tratamento a sialoadenectomia sublingual e mandibular. Cerca de dez diasapós a última cirurgia o cão não apresentava mais aumento de volume da área afetada e não havia sinais de alteração quanto àprodução de saliva. O tratamento sugerido proporcionou bons resultados promovendo a reparação tecidual e reestruturação dolocal afetado e diminuindo o índice de recidiva.(AU)

The sublingual mucocele is a rare disease in dogs, but very important for veterinary medicine due to losses generated by itsconsequences. Thus, this report aims to describe the case of sublingual mucocele in a dog with subsequent relapse in mandibularand sublingual gland and discuss their importance to veterinary medicine. It was the Veterinary Hospital Dix-Huit Rosado Maia -HOVET / Universidade Federal Rural de Semi-árido (UFERSA), a male dog with one year and 10 months, an increase of bilateralvolume in the sublingual region for approximately two months. After clinical examination was suspected of mucocele of bilateralsublingual gland (ranula) indicating the treatment of sublingual left gland resection due to nodular and marsupalização the rightsublingual gland. After one month of a medical release the animal returned to HOVET - UFERSA with emergence of complaint froma further increase in sublingual volume and cervical-ventral region suspecting it is a possible cervical mucoceles and recurrenceof sublingual mucocele left. It is stated as a treatment to sublingual and mandibular sialoadenectomy. About ten days after the lastsurgery, the dog had no more swelling of the affected area and no signs of change with saliva production. However, the suggestedtreatment provided good results by promoting tissue repair and restructuring of the affected area and decreasing the recurrence rate.(AU)

Morphometric alteration of intestinal epithelium of rats (Rattus norvegicus) submitted to the technique of enteropexy

Background: Due to the numerous complications that enteropexy may cause in domestic animals and humans, this study aimed at investigating the microscopic level, the damage generated by this technique in mice, in order to investigate the morphometric changes caused by enteropexy technique in rats. Materials, Methods & Results: Eighteen Wistar rats were submitted to surgical technique of enteropexy. To evaluate intestinal disorders they were euthanized at 30 (Group I), 60 (group II) and 90 (group III) days after the procedure. The animals were perfused with 2.5% glutaraldehyde and 4% paraformaldehyde for the removal of intestinal fragments for analysis in conventional microscopy and scanning electron microscopy. In classical histopathology, group I presented mild lesions with necrosis of the epithelium and infiltration of mononuclear cells. After 60 days, extensive ischemic necrosis area was observed, characterized by the denudation of epithelium cells and cellular debris in the lumen surface and loss of intestinal crypts. After 90 days (group III) lesions were evident and were characterized by strong coagulative necrosis of epithelial cells and intestinal crypts. Under electron microscopy, group I showed early fusion of the adjacent intestinal walls. After 60 days there was adherence of luminal stenosis and intestinal walls. In group III loss of epithelium and substitution [...](AU)

Aspectos clínicos da dermatite atópica em cães oriundos de uma clínica especializada em dermatologia veterinária na cidade de Natal-RN / Clinical aspects of atopic dermatitis in dogs coming at a veterinary dermatology clinic in the cityof Natal, RN

A dermatite atópica canina é definida como uma enfermidade cutânea pruriginosa, com predisposiçãogenética, porém multifatorial. Desponta uma grande importância na área da dermatologia e alergologiaveterinária por corresponder a uma doença de curso crônico, com sintomatologia clássica, atípica ougrave. O presente trabalho objetivou a descrição clínica de cães atópicos oriundos da capital potiguarbrasileira. Analisaram-se 27 atendimentos com diagnóstico de dermatite atópica canina.Buscou-se caracterizar a enfermidade conforme a idade do animal,raça, gênero sinais clínicos (e respectivas localizaçõesanatômicas) e complicações secundárias.Dos 27 pacientes acometidos com dermatite atópica, 52% eram fêmeas e 48% machos. Dentre o padrão racial,houve predominância do Poodle (33,33%), seguido doMaltês (18,52%).Com relação à faixa etária, detectou-se uma média de 4,14 anos. O prurido foi evidenciadoem 100% dos animais, principalmente na região digital/interdigital. Dentre as complicações associadas, destacou-se a piodermite bacteriana e a otite, ambas com frequência de 29,63%. Para a localização das lesões, a forma disseminada foi a mais prevalente (48,15% dos casos). Em caninos nativos da capital potiguar do Brasil, com histórico de dermatopatia alérgica crônica, deve-se considerar a possibilidade de atopia. (AU)

The canine atopic dermatitis is defined as an itchy skin disease with genetic predisposition, howevermultifactorial. Great importance stands out in the field of veterinary dermatology and allergy as itcorresponds to achronic disease, with classic symptoms, atypicalor severe. The study aimed to a clinical description of atopic dogs coming from Natal, Brazil. Twenty seven (27) animals with a diagnosis of canine atopic dermatitis were analyzed. It was sought to characterize the disease according to the animals age, race, sex, clinical signs (and their anatomical locations) as well as secondary complications. It was observed that out of the 27patients affected with atopic dermatitis, 52% were femalesand 48%males.Amongtheracial pattern, predominated Poodle(33,33%), followed by Maltese(18,52%).Regarding the age group, we detected an average of 4,14years.The it ching was evidenced in100% ofthe patients, mainly in the digital/interdigital region. Among the associated complications, bacterialpyoderma and otitis were noteworthy, both with frequency of29,63%. For the location of the lesions, it was perceived prevalence of disseminated kind, being present in 48,15% of the animals. In canine native of Natal in Brazil, with a history of chronic allergic skin disease, one should consider the possibilityof atopy. (AU)
