In the eye of the storm: iodinated contrast medium induced thyroid storm presenting as cardiopulmonary arrest.

The administration of iodinated contrast medium may lead to excess free thyroid hormone release and cause thyroid storm. A woman presented to the emergency department with dyspnea, hemoptysis, and intermittent bilateral lower extremities edema. Physical examination revealed mildly enlarged thyroid. Patient underwent a computed tomography scan of the chest with intravenous iodinated contrast medium to rule out pulmonary embolism, the patient developed a thyroid storm second to iodinated contrast medium injection. Proper treatment was provided and the patient had a good outcome. We present this case of an unusual presentation of a thyroid storm with cardiac arrest. This case illustrates that evaluating thyroid function tests in patients with an enlarged thyroid prior to the administration of iodinated contrast medium could prevent the development of thyroid storm.

Chronic kidney disease and diabetes.

Chronic kidney disease has a significant worldwide prevalence affecting 7.2% of the global adult population with the number dramatically increasing in the elderly. Although the causes are various, diabetes is the most common cause of CKD in the United States and an increasing cause of the same worldwide. Therefore, we chose to focus on diabetic chronic kidney disease in this review. The pathogenesis is multifactorial involving adaptive hyperfiltration, advanced glycosylated end-product synthesis (AGES), prorenin, cytokines, nephrin expression and impaired podocyte-specific insulin signaling. Treatments focus on lifestyle interventions including control of hyperglycemia, hypertension and hyperlipidemia as well treatment of complications and preparation for renal replacement therapy. This review examines the current literature on the epidemiology, pathogenesis, complications and treatment of CKD as well as possible areas of future disease intervention.

Primary hyperparathyroidism: Skeletal and non-skeletal effects, diagnosis and management.

Primary hyperparathyroidism (PHPT) is the third most common endocrinopathy seen today, and is most frequently found in the 6th to 7th decade of life. PHPT can present with various degrees of symptoms, and can affect many organ systems, including the skeletal, renal, central nervous system and cardiovascular system. Despite this, the most common presentation of hyperparathyroidism is "asymptomatic" with the diagnosis being made incidentally with the initial finding of hypercalcemia on routine laboratory studies, leading to further investigation. Surgical versus medical management is usually based on factors such as age and complications related to hyperparathyroidism (i.e. the presence of renal stones, renal insufficiency and bone loss and significant increases in serum calcium). Treatment options include parathyroidectomy, bisphosphonates, calcitonin and calcimimetics. In this review, we discuss primary hyperparathyroidism in detail with a focus on clinical manifestations particularly in the elderly population. We highlight the indications for surgical versus medical management and compare some of the uses of newer therapeutic agents relative to traditional ones.
