Presumed pituitary apoplexy in 26 dogs: Clinical findings, treatments, and outcomes.

ABSTRACT:

Background

Pituitary apoplexy refers to hemorrhage or infarction within the pituitary gland resulting in acute neurological abnormalities. This condition is poorly described in dogs.

Objectives

To document presenting complaints, examination findings, endocrinopathies, magnetic resonance imaging (MRI), treatments, and outcomes of dogs with pituitary apoplexy.

Animals

Twenty-six client-owned dogs with acute onset of neurological dysfunction.

Methods

Retrospective case series. Dogs were diagnosed with pituitary apoplexy if MRI or histopathology documented an intrasellar or suprasellar mass with evidence of hemorrhage or infarction in conjunction with acute neurological dysfunction. Clinical information was obtained from medical records and imaging reports.

Results

Common presenting complaints included altered mentation (16/26, 62%) and gastrointestinal dysfunction (14/26, 54%). Gait or posture changes (22/26, 85%), mentation changes (18/26, 69%), cranial neuropathies (17/26, 65%), cervical or head hyperpathia (12/26, 46%), and hyperthermia (8/26, 31%) were the most frequent exam findings. Ten dogs (38%) lacked evidence of an endocrinopathy before presentation. Common MRI findings included T1-weighted hypo- to isointensity of the hemorrhagic lesion (21/25, 84%), peripheral enhancement of the pituitary mass lesion (15/25, 60%), brain herniation (14/25, 56%), and obstructive hydrocephalus (13/25, 52%). Fifteen dogs (58%) survived to hospital discharge. Seven of these dogs received medical management alone (median survival 143 days; range, 7-641 days) and 8 received medications and radiation therapy (median survival 973 days; range, 41-1719 days).

Conclusions and clinical importance

Dogs with pituitary apoplexy present with a variety of acute signs of neurological disease and inconsistent endocrine dysfunction. Dogs that survive to discharge can have a favorable outcome.

Project description:Background contextThis is the first study to systematically evaluate the value of a longer treatment period for massage. We provide a framework of how to conceptualize an optimal dose in this challenging setting of nonpharmacologic treatments.PurposeThe aim was to determine the optimal dose of massage for neck pain.Study design/settingTwo-phase randomized trial for persons with chronic nonspecific neck pain. Primary randomization to one of five groups receiving 4 weeks of massage (30 minutes 2x/or 3x/wk or 60 minutes 1x, 2x, or 3x/wk). Booster randomization of participants to receive an additional six massages, 60 minutes 1x/wk, or no additional massage.Patient sampleA total of 179 participants from Group Health and the general population of Seattle, WA, USA recruited between June 2010 and August 2011 were included.Outcome measuresPrimary outcomes self-reported neck-related dysfunction (Neck Disability Index) and pain (0-10 scale) were assessed at baseline, 12, and 26 weeks. Clinically meaningful improvement was defined as greater than or equal to 5-point decrease in dysfunction and greater than or equal to 30% decrease in pain from baseline.MethodsClinically meaningful improvement for each primary outcome with both follow-up times was analyzed using adjusted modified Poisson generalized estimating equations (GEEs). Secondary analyses for the continuous outcomes used linear GEEs.ResultsThere were no observed differences by primary treatment group at 12 or 26 weeks. Those receiving booster dose had improvements in both dysfunction and pain at 12 weeks (dysfunction: relative risk [RR]=1.56 [1.08-2.25], p=.018; pain: RR=1.25 [0.98-1.61], p=.077), but those were nonsignificant at 26 weeks (dysfunction: RR=1.22 [0.85-1.74]; pain: RR=1.09 [0.82-1.43]). Subgroup analysis by primary and booster treatments found the booster dose only effective among those initially randomized to one of the 60-minute massage groups.Conclusions"Booster" doses for those initially receiving 60 minutes of massage should be incorporated into future trials of massage for chronic neck pain.
