Cecal dilatation and distension in a Holstein calf

Cecal dilatation and distention is an important disorder in early lactation dairy cows, however, reports describing the anatomical pathology findings of this condition are scarce in the literature. Etiopathogenesis of cecal dilatation and distention is often attributed to high concentrate feeds, but there is also evidence of myoelectrical dysfunction contributing to its occurrence. Diagnosis is often made based on physical exam findings, with the contribution of ancillary exams. This paper aims to describe a case of cecal dilatation with clinical, laboratorial and pathology findings of a 5-month-old Holstein calf that presented abdominal distension, positive succussion of the right flank and mild dehydration. Clinical pathology findings included neutrophilic leukocytosis with regenerative left shift and elevated ruminal chloride. Ultrasonographic examination of the right abdomen showed distended and hypomotile intestinal loops. Despite that, due to the patients age, which prevented rectal palpation, and lack of some characteristic clinical and clinical pathology findings, diagnosis was only possible post mortem. Macroscopical and microscopical findings demonstrated cecum dilatation with edema, hemorrhage and thrombi. Despite being well known by large animal clinics, anatomical pathologists must be aware of this condition.(AU)

Hipercrescimento dentário e má oclusão em Porquinho-da-Índia (Cavia porcellus) / Dental overgrowth and malocclusion in guinea pig (Cavia porcellus)

Dental overgrowth and malocclusion are a common problems in the clinic of rodentsraised as companion animals. A guinea pig was attended in a private clinic with clinicalsigns compatible with dental overgrowth and malocclusion, condition that wasdiagnosed by radiography. Despite attempts at treatment, the animal was affected bymany relapses and was euthanized.

Diagnóstico presuntivo de Osteomielite em coelho (Oryctolagus cuniculus) / Presumptive diagnosis of rabbit Osteomyelitis (Oryctolagus cuniculus)

A variety of organisms have been implicated in bone infections such as bacteria and fungi.A male rabbit, with a history of locomotion difficulty, with the presence of a foot injury inboth posterior limbs, characterizing bubble foot, which were already ulcerated, edema inthe tarsal joints, besides the presence of pus in the region. An x-ray of the posterior limbswas requested, with areas of osteolysis being observed. The animal's history andradiographic result were used to give a presumptive diagnosis of osteomyelitis. Astreatment, enrofloxacin therapy was instituted, in addition to cleansing the pododermitewith iodine at 1%. The animal did not present improvement in the clinical picture, beingsubmitted to euthanasia.

Uso de doramectina no tratamento de sarna causada por ácaro do gênero Cheyletiella sp. em coelho (Oryctolagus cuniculus) / Use of doramectin in the treatment of scabies caused by mites of the genus Cheyletiella sp. in rabbit (Oryctolagus cuniculus)

Skin diseases in rabbits can often be caused by mites. A rabbit, male, of unknown age,was attended in a private clinic with severe itch and crusting in the auricle. The scrapingof skin was positive for the presence of the mite Cheyletiella sp. The treatment wasefficient and consisted of the use of doramectin 0,4 mg/kg during five weeks.
