ReviewEndocrine dysregulation in critically ill foals and horses.
Critical illness challenges many endocrine homeostatic systems to overcome diseases, stress, and hostile conditions that threaten survival. Coordinated and consecutive responses by the autonomic nervous system, endocrine metabolic adaptations to mobilize and conserve energy and electrolytes, cardiovascular adjustments to maintain organ perfusion, and immunomodulation to overcome infections and inflammation are required. Because most admissions to equine intensive care units are related to horses with gastrointestinal disease and septic foals, most endocrine information during critical disease are generated from these populations. This article presents an overview on endocrine responses to critical illness in horses and foals and also some comparative information.

ReviewWater homeostasis and diabetes insipidus in horses.
Diabetes insipidus (DI) is a rare disorder of horses characterized by profound polyuria and polydipsia (PU/PD), which can be caused by loss of production of arginine vasopressin (AVP). This condition is termed neurogenic or central DI. ⋯ Equine clinicians may differentiate true DI from more common causes of PU/PD by a systematic diagnostic approach. DI may not be a correctable disorder, and supportive care of affected horses requires an adequate water source.

ReviewDisorders of calcium and phosphate metabolism in horses.
Calcium and phosphate have structural and nonstructural functions, and their concentrations in the extracellular compartment are affected by the physiologic status of the animal as well as diseases. Important progress in understanding calcium and phosphorus metabolism in healthy and diseased horses and foals has been made in recent years. ⋯ One critical point in the homeostasis of these minerals is their interaction and interdependence with other ions, including potassium and magnesium. In this review, the author provides a clinical overview on disorders of calcium and phosphate in the horse.
