Additionally, to determine whether there is any correlation between the ultrasonographic findings in lesional skin and local Canine Atopic Dermatitis Extent and Severity Index, 4th iteration (CADESI‐04) or its domains (erythema, lichenification, excoriations/alopecia). As a secondary aim, six cAD dogs were re‐evaluated after management intervention.AnimalsTwenty dogs with cAD (six were re‐examined after treatment) and six healthy dogs.Materials and MethodsIn all dogs, ultrasonographic examination was performed on the same 10 skin sites, using a 50 MHz transducer. Wrinkling of skin surface, presence/width of subepidermal low echogenic band, hypoechogenicity of dermis and thickness of the skin were evaluated and scored/measured blindly.ResultsDermal hypoechogenicity was more common and severe in lesional compared to macroscopically nonlesional skin of dogs with cAD. In lesional skin, presence/severity of wrinkling of skin surface and of dermal hypoechogenicity were positively correlated with presence/severity of lichenification, while severity of dermal hypoechogenicity was positively correlated with local CADESI‐04. A positive correlation between the change in skin thickness and the change in the severity of erythema during treatment was noted.Conclusions and Clinical RelevanceHigh‐frequency ultrasound biomicroscopy may be useful for the evaluation of skin of dogs with cAD and for evaluating the progression of skin lesions during treatment.

A 3-year-old, client-owned, neutered male DSH cat was referred with one-month history of three generalized tonic-clonic seizures and intermittent left thoracic limb spontaneous knuckling. Nine months ago, the animal had been bitten on the head by a wild carnivore. Prior to the traumatic event the cat was reported to be neurologically normal. On admission, physical examination was unremarkable. Neurological examination revealed left hemi-neglect syndrome, characterised by decreased postural reactions on the left thoracic and pelvic limb, and absent menace bilaterally, most likely post-ictal. Neuroanatomical localisation was right forebrain. Haematology, biochemistry and bile acid stimulation test were unremarkable. Blood serology for Toxoplasma gondii, FIV, FeLV and FCoV were all negative. MRI of the head revealed protrusion of brain and meninges into the right frontal sinus, mild meningeal contrast uptake of the protruding tissue and the adjacent brain in the calvarium. CSF analysis was unremarkable. Final diagnosis was traumatic frontoethmoidal meningoencephalocele with late-onset forebrain syndrome due to presumptive post-traumatic encephalomalacia. The cat remained seizure-free on the four-month follow-up. This is the first report of traumatic meningoencephalocele in small animals. The finding in this case emphasizes the importance of a complete neurological investigation in patients with history of head trauma despite the absence of initial neurological signs. Differentials for delayed neurological signs after traumatic meningoencephalocele include encephalomalacia, recurrent meningitis with/without CSF rhinorrhea or cerebral ischaemic infarction

It has been proposed as a model for human Type 2 DM given many shared features. Small case studies demonstrate feline DM also occurs as a result of insulin resistance due to a somato-trophinoma. The current study estimates the prevalence of hypersomatotropism or acro-megaly in the largest cohort of diabetic cats to date, evaluates clinical presentation and ease of recognition. Diabetic cats were screened for hypersomatotropism using serum total insulin-like growth factor-1 (IGF-1; radioimmunoassay), followed by further evaluation of a subset of cases with suggestive IGF-1 (>1000 ng/ml) through pituitary imaging and / or histo-pathology. Clinicians indicated pre-test suspicion for hypersomatotropism. In total 1221 dia-betic cats were screened; 319 (26.1%) demonstrated a serum IGF-1>1000 ng/ml (95% confidence interval: 23.6–28.6%). Of these cats a subset of 63 (20%) underwent pituitary imaging a...

Indications to perform an ultrasonographic examination of the urinary tract include: serum biochemistry findings, physical findings, species or age-related indications (e.g. breeds with familial renal disease, suspicion of congenital abnormalities in young animals) and radiographic findings that include abnormal appearing kidneys and/ or urinary bladder.
