Objective: To describe acute cerebral compression caused by an epidural hematoma (EDH) in a dog with cryptococcal infection.
Case Summary: An 18-month-old neutered male Neapolitan Mastiff was found comatose with no preceding clinical signs apart from a mild forelimb lameness. A CT scan of the head revealed a lesion within the right caudal nasal cavity that traversed the cribriform plate in addition to a right epidural lesion resulting in compression of the right cerebrum. Assessment of brain death was made based on the presence of coma, apnea, and absence of brain stem reflexes and included assessment of the vestibulo-ocular reflex. Postmortem identified a large EDH causing marked compression of the right frontal lobe. A nasal biopsy cultured Cryptococcus gattii.
New Or Unique Information Provided: EDH formation in a dog secondary to cryptococcosis has not been previously reported. This is also the first time a caloric vestibulo-ocular reflex assessment has been reported in a dog.

Voluntary movement, motivation, and reinforcement learning depend on the activity of ventral midbrain neurons, which extend axons to release dopamine (DA) in the striatum. These neurons exhibit two patterns of action potential activity: low-frequency tonic activity that is intrinsically generated and superimposed high-frequency phasic bursts that are driven by synaptic inputs. acute striatal brain preparations are widely employed to study the regulation of evoked DA release but exhibit very different DA release kinetics than recordings.

Background And Purpose: Pituitary adenylate cyclase activating polypeptide (PACAP) is a human migraine trigger that is being targeted for migraine. The δ-opioid receptor (δ-receptor) is a novel target for the treatment of migraine, but its mechanism remains unclear. The goals of this study were to develop a mouse PACAP-headache model using clinically significant doses of PACAP; determine the effects of δ-receptor activation in this model; and investigate the co-expression of δ-receptors, PACAP and PACAP-PAC1 receptor.

A knowledge gap may exist when attempting to identify the pathogenetic mechanisms resulting in the syndrome of inappropriate antidiuretic hormone (SIADH) or hypotonic hyponatremia. Ectopic secretion of antidiuretic hormone [ADH] is the classic cause of SIADH. But another form of inappropriate secretion of ADH occurs when interleukin 6 is activated.

Forecasting the progression of the disease in the early inflammatory stage of the most prevalent type of multiple sclerosis (MS), referred to as relapsing-remitting multiple sclerosis (RRMS), is essential for making prompt treatment modifications, aimed to reduce clinical relapses and disability. In total, 58 patients with RRMS, having an Expanded Disability Status Scale (EDSS) score less than 4, were included in this study. Baseline magnetic resonance imaging (MRI) was performed, and brain and spinal cord lesions were evaluated.
