This study showed an elevated ALT and an abnormal gallbladder wall to be biomarkers significantly associated with anaphylaxis in dogs with acute hypersensitivity reactions.

The prognosis for acute spinal injury is varied and is dependent upon the presence of concurrent trauma, location, and type of primary injury sustained, and extent of neurologic impairment at the time of initial presentation. The etiology of the underlying trauma is of great importance in determining prognosis and outcome. Loss of deep pain is generally accepted as a poor prognostic indicator; however, even these patients can recover depending on their response to treatment.

Objective: To review the pathophysiology, diagnosis, current treatment, and prognosis of heatstroke. Etiology: Heatstroke can be a life-threatening condition occurring because of an imbalance of heat dissipation and production. Certain factors may predispose some animals to heatstroke. The pathophysiology and sequelae of heatstroke share similarities with that of sepsis; thus, multiple organ dysfunction often ensues. The pathophysiological derangements that occur with heatstroke result from a complex series of events associated with direct cytotoxicity of heat and initiation of the acute-phase response by endotoxin, inflammatory cytokines, and chemokines. Activation of endothelial cells, coagulation factors, and fibrinolysis (with ensuing microvascular thrombosis) leads to hypoxia and organ dysfunction. Heat shock proteins produced secondary to sudden heating act as protein chaperones or molecular guardians to provide protection against future heatstroke and may be implicated as a possible genetic component of heatstroke.Diagnosis: A history of recent exercise or being confined in a hot and/or humid environment, combined with clinical signs such as body temperature above 401C (1041F), panting, tachycardia, hyperemia, dry mucous membranes, and depression to prostration is consistent with a diagnosis of heatstroke. A complete blood count performed during the initial examination of dogs with suspected heatstroke often includes nucleated red blood cells. Therapy: The mainstays for treating heatstroke include rapid evaporative cooling, volume replacement to provide cardiovascular support, and management of secondary complications. Prognosis: The prognosis is multifactorial. There is a significant negative correlation between comatose mental status, decreased temperature, and hypoglycemia with mortality.

This study suggests that RIV at a median dose of 0.89 mg/kg by mouth once daily was safe and well tolerated in a small group of dogs with presumed pIMHA able to tolerate oral medications and treated with a standardized immunosuppressive treatment protocol. Conclusions regarding the relative efficacy of RIV as compared to CL and LDA cannot be made due to the small size of the treatment groups and because pharmacodynamic effects were not assessed.

It is apparent that TF and TFPI are important in health and disease. An enhanced understanding of the physiologic and pathophysiologic roles of these factors provides better insight into coagulation, inflammation, angiogenesis, disseminated intravascular coagulation, and tumor metastasis. This greater understanding may provide for the development of therapeutics for sepsis, disseminated intravascular coagulation, and neoplasia.
