The feasibility of inducing protective immunity to Acanthamoeba keratitis was tested in a pig model. Experiments were designed to determine if ocular infection with Acanthamoeba trophozoites would elicit protection against reinfection. Additional experiments examined whether injection of parasite antigens either intramuscularly, subconjunctivally, or by(More)
Type 2 diabetes mellitus (T2DM) continues to rise in prevalence in the United States and worldwide. Despite advances in medical treatments for T2DM, many patients remain uncontrolled. By targeting centrally mediated pathways of glucose metabolism, bromocriptine represents a novel therapeutic option in T2DM. Several small clinical trials demonstrate(More)
OBJECTIVE To review the pertinent basic and clinical research describing the complex effects of excess thyroid hormone on carbohydrate metabolism. METHODS We performed a MEDLINE search of the English-language literature using a combination of words (ie, "thyrotoxicosis and diabetes," "diabetic ketoacidosis and thyroid storm," "carbohydrate metabolism and(More)
Hypocalcemia is a well-known complication of total thyroidectomy. Patients who have previously undergone gastric bypass surgery may be at increased risk of hypocalcemia due to gastrointestinal malabsorption, secondary hyperparathyroidism, and an underlying vitamin D deficiency. We present the case of a 58-year-old woman who underwent a total thyroidectomy(More)
Modern medical practices allow patients to survive acute insults and be sustained by machinery and medicines for extended periods of time. We define chronic critical illness as a later stage of prolonged critical illness that requires tracheotomy. These patients have persistent elevations of inflammatory cytokines, diminished hypothalamic-pituitary(More)
OBJECTIVE Patients who remain critically ill for prolonged periods and require tracheotomy, defined as chronic critical illness (CCI), display elevated levels of bone resorption. The measurement of bone turnover markers reveals that osteoclastic bone resorption is not only enhanced but also uncoupled from osteoblastic bone formation. We examine the effect(More)
Insulin resistance is common and often multifactorial in acutely critically ill patients. At our institution, glycemic control is achieved in these patients using an intravenous insulin protocol. The authors present a case in which a patient developed severe insulin resistance following surgical repair of a thoracic aorta aneurysm. Postoperatively, the(More)
Bariatric surgery is an effective treatment option for obesity. Commonly utilized procedures are either restrictive, malabsorptive, or both. Substantial weight loss can be achieved. Postoperatively, patients experience nutritional, metabolic, and hormonal changes that have important clinical implications. The postoperative diet should be advanced carefully,(More)
Both glycemic control and adequate nutrition support impact the clinical outcome of hospitalized patients. Providing nutrition to malnourished patients using the enteral or parenteral route may increase the risk of hyperglycemia, especially in patients with diabetes. Hyperglycemia can be managed through the use of enteral tube feeds with reduced(More)
