Randomized Controlled Trial Clinical Trial
Are the metabolic effects of rosiglitazone influenced by baseline glycaemic control?
To compare the metabolic effects of rosiglitazone, an antidiabetic agent of the thiazolidinedione class, in patients with type 2 diabetes with fair to moderate glycaemic control (glycosylated haemoglobin (HbA(lc)) < 9%) and poor glycaemic control (HbA(lc) > or = 9%). ⋯ Rosiglitazone significantly improved HbA(lc) and FPG levels in patients with type 2 diabetes, with the greatest improvements observed in patients with baseline HbA(lc) levels > or =9%.

Diabetes mellitus is a chronic disease that is monitored by measurement of haemoglobin A1c (A1C) as an index of glycaemic control. The limitations of using A1C, given the consensus clinical practice recommendations made by the American Diabetes Association, need to be better understood by clinicians. ⋯ Laboratories need to report current values and the analyse six internal quality control specimens for each analytical run. 'Delta check' criteria ought to be applied and results reported to highlight acute deviations in A1C. Such procedures will aid the attainment of the clinical quality requirements and give appropriate results for audit purposes.

Stress urinary incontinence (SUI) is the involuntary loss of urine associated with physical activities such as running, jumping, or lifting, or with sneezing and coughing. For many patients it can be a very bothersome symptom, causing social isolation, loss of self-esteem, and increased expenses. ⋯ This paper reviews the current pharmacological treatment options for SUI, describing the mechanism of action, efficacy, and possible adverse effects of each. A new centrally-acting compound with dual activity as a balanced serotonin and norepinephrine reuptake inhibitor, duloxetine, may offer a promising new approach for treatment.

Measurement of glycosylated hemoglobin (HbA1c) remains the gold standard for the assessment of glycemic control in patients with type 2 diabetes. Recent investigations have studied the correlations between HbA1c levels and other aspects of glucose metabolism, specifically, postprandial glucose (PPG) and fasting plasma glucose (FPG). The results suggest that PPG is also important to overall glycemic control and may be a better index of glucose regulation than FPG. ⋯ Many patients receive combination therapy, thereby benefiting from multiple mechanisms of glucose control, although in most cases insulin must later be added to the regimen in order to effectively suppress FPG. Thus, all aspects of glucose metabolism appear to be clinically relevant and should be monitored for effective diabetes management. Further study will more precisely define the clinical significance of PPG.

Comparative Study
Utilization patterns and net direct medical cost to Medicaid of irritable bowel syndrome.
Patients with irritable bowel syndrome are frequent users of the health care system. ⋯ Irritable bowel syndrome was shown to impose an economic burden on the Medicaid program. The cost of treating patients with irritable bowel syndrome is higher than the cost of treating matched ambulatory Medicaid recipients without the condition.
