Disorders of mineral metabolism are common in both the office and hospital setting. The diagnosis can be simplified by remembering the target organs involved--intestine, kidney, and bone--and by assessing the presence of kidney disease, levels of parathyroid hormone, and vitamin D status. Although the list of possible causes for these derangements is long, most patients who have hypercalcemia have hyperparathyroidism or malignancy; those who have hypocalcemia, hypophosphatemia, and hypomagnesemia have reduced gastrointestinal absorption, and those who have hyperphosphatemia and hypermagnesemia have increased intake in the setting of kidney disease.

Both acute and chronic sinusitis are common diseases associated with significant morbidity and consumption of health care dollars. Acute sinusitis is caused by an infectious process and can often be difficult to distinguish from a viral upper respiratory infection, as signs, symptoms, and even the results of most diagnostic tests overlap. In contrast, chronic sinusitis is an inflammatory disease and, contrary to common practice, long term antibiotics are likely not useful. This article reviews the diagnosis and management of both acute and chronic sinusitis and includes discussion of the prevalence of disease, our current understanding of disease pathogenesis, diagnosis, and contemporary treatment.

Continuous subcutaneous insulin infusion has provided patients who have diabetes with a system for achieving treatment targets with a lower incidence of severe hypoglycemia. Patients prefer the flexibility, convenience, and physiologic glycemic control of continuous subcutaneous insulin infusion. Future insulin pumps will be implanted within the body and the "loop" will be closed, providing a physiologic insulin delivery system. This system will provide the means for achieving near-normal glycemia, limit episodes of severe hypoglycemia, and prevent long-term complications of diabetes mellitus.
