We investigated whether patients' perceived glycemic control and self-reported diabetes self-care correlated with their actual glycemic control.
A survey was administered among patients with diabetes mellitus at an outpatient clinic with structured self-report questionnaires regarding perceived glycemic control and diabetes self-management. Actual glycemic control was defined as a change in glycated hemoglobin (A1C) or fasting plasma glucose (FPG) since the last clinic visit.
Patients who perceived their glycemic control as "improved" actually showed a mild but significant decrease in the mean A1C (-0.1%,
Patients should be encouraged to assess and monitor diabetes self-care more objectively to motivate behavioral modifications and improve their actual glycemic control.

The current perception threshold (CPT) could be quantified by stimulating Aβ and C fibers at 2,000 and 5 Hz, respectively. C fibers play a role in the autonomic nervous system and are involved in temperature and pain sensation. We evaluated the usefulness of CPT for diagnosing distal polyneuropathy (DPN) and cardiovascular autonomic neuropathy (CAN) in diabetic patients.
The CPT was measured in the index finger (C7 level) and in the third toe (L5 level) in diabetic patients aged 30 to 69 years. We assessed DPN according to the neuropathy total symptom score-6 (NTSS-6) and 10-g monofilament pressure sensation. Subjects with a NTSS-6 >6 or with abnormal 10-g monofilament sensation were defined to have DPN. CAN was evaluated by spectral analysis of heart rate variability and by Ewing's traditional tests.
The subjects with DPN had significantly higher CPT at all of the frequencies than the subjects without DPN (
Although the CPT is significantly associated with neuropathic symptoms or signs corresponding to the nerve fiber stimulated, it provides little additional information compared with conventional evaluations.

Patients with type 2 diabetes who require insulin therapy are commonly elderly and have poor visual acuity. In this study, we examined the clinical usefulness of the indicator magnifying window (IMW) for elderly patients with type 2 diabetes. We recruited 50 patients with type 2 diabetes over the age of 60 who had used insulin pens for glucose control. They were asked to set the insulin pen at randomly selected doses with or without an IMW. We assessed dosing accuracy, convenience, self-confidence, need for eyeglasses, preference, and willingness to recommend the IMW to other patients. Although the IMW did not improve the dosing accuracy or convenience, it significantly decreased the need for eyeglasses. Overall, the clinical usefulness of the IMW is quite limited in elderly patients with type 2 diabetes.
