Neurocognitive functioning in children diagnosed with diabetes before age 10 years.
Our objective was to determine scores on tests of neurocognitive functioning in children diagnosed with diabetes before age 10 years and to determine the association of age of diagnosis, duration of diabetes, subtle hypoglycemia, severe hypoglycemia, and history of hypoglycemic seizures with these neurocognitive test scores. Fifty-five of 62 eligible patients with a mean age of 7.9 +/- 1.6 years followed in our center were given the Woodcock-Johnson Psychoeducational Battery, Beery Developmental Test of Visual-Motor Integration, Finger Tapping, Grooved Pegboard, and Verbal Selective Reminding tests to evaluate the following domains: memory/attention, visual-perceptual, broad cognitive function, academic achievement, and fine motor speed/coordination. Fifteen age-matched siblings served as controls. ⋯ However, specific aspects of neurocognitive functioning may be adversely affected by having had a hypoglycemic seizure, but not by episodes of severe hypoglycemia without seizure. Lower HbA1c and an increase in the number of blood glucose levels less than 70 mg/ dL (subtle hypoglycemia) which were associated with higher scores in some domains of academic achievement and memory suggests that stable glycemia may influence cognitive abilities and/or that successful diabetes management requires cognitive skills. Strategies to diminish the risk of seizures with hypoglycemia should be investigated.

Comparative StudyOutcome of trigger finger treatment in diabetes.
Trigger finger is an underdiagnosed hand disorder causing disability in longstanding diabetic patients. Sixty diabetic patients [39 insulin-dependent diabetes mellitus (IDDM) and 21 non-insulin-dependent diabetes mellitus (NIDDM)] and 60 nondiabetic patients were examined. All were initially treated by steroid injections: failure to alleviate symptoms was the indication for surgery. ⋯ Diabetic patients should be diagnosed early for multiple and diffuse types of trigger digits. Steroid injection as the first mode of therapy is highly recommended although not always successful. Surgery is the definitive treatment but requires a long course of physiotherapy and may be associated with some complications.

Comparative StudyPulse oximetry for the assessment of autonomic neuropathy in diabetic patients.
Altered vascular responses to various thermal stimuli correlate well with the changes of autonomic neuropathy. These responses were assessed by the use of pulse oximetry. Standard cardiac autonomic function tests were performed in normal subjects (n = 12), diabetic patients without autonomic neuropathy (n = 8), and diabetic patients with autonomic neuropathy (n = 7). ⋯ In diabetics with autonomic neuropathy, the rate of fall in percentage oxygen saturation was significantly slower (p < 0.0001), less intense (p < 0.0001) and with delayed subsequent recovery (p = 0.013), compared to normal subjects. Rebound rise in oxygen saturation was absent in all the diabetics with autonomic neuropathy, compared to 2 of 12 normal subjects (p < 0.0001). We conclude that pulse oximetry may be a potentially useful, simple, and noninvasive bedside method for assessment of diabetic autonomic neuropathy.

Comparative StudyCerebrospinal fluid levels of beta endorphin in painful and painless diabetic polyneuropathy.
beta endorphin (beta-EP) is an important modulator of central pain pathways. To examine whether changes in central production of beta-EP contribute to the pathogenesis of diabetic neuropathic pain, we compared the cerebrospinal fluid (CSF) levels of beta-EP and its precursor proopiomelanocortin (POMC) between 15 diabetic patients with chronic painful diabetic polyneuropathy, eight patients with severe painless diabetic neuropathy, and ten nondiabetic controls. Both peptides were measured by specific monoclonal antibody-based two-site immunoradiometric assays (IRMAs). ⋯ However, POMC levels were 80-fold higher than those of beta-EP and should always be considered when interpreting immunoreactive beta-EP or other derivative peptide levels in CSF. We conclude that CSF beta-EP levels appear to be reduced in diabetic polyneuropathy but they do not relate to the presence of neuropathic pain. This might explain why opioid analgesics are of little, if any, help in alleviating diabetic neuropathic pain.
