Evaluation of blood glucose measurement techniques: locating sources of error.

Researchers evaluating the accuracy of rapid blood glucose monitoring (RBGM) techniques have often concluded that RBGM was sufficiently accurate for clinical use. However, investigators of patients' use of RBGM have more often reported unacceptable levels of accuracy and have shown individual differences between patients in the level of accuracy attained. Responsibility for excessive errors has commonly been attributed to patients' inadequacy in using RBGM. The logic of such attributions is questioned. Data are presented which indicates that errors attributed to patient inaccuracy may actually be due to (a) inaccuracy of reference blood glucose determinations used to evaluate patients' accuracy and (b) variable accuracy of RBGM techniques dependent on the range of blood glucose levels: some patients may appear to be less accurate than others simply because their blood glucose levels fall into a range less accurately measured by the RBGM technique. Furthermore, data presented reveal batch to batch variation in accuracy of the particular reagent strips used. Such variation between batches may help to account for inconsistencies between RBGM evaluation studies in which apparently identical reagent strips were used.

Accuracy of subjective blood glucose estimation by patients with insulin-dependent diabetes.

A between-groups design using a baseline, treatment, follow-up procedure was used to investigate the accuracy of 20 patients with insulin-dependent diabetes when subjectively estimating their blood glucose levels. Patients were encouraged to attend to their mood for cues when making estimates of their blood glucose. Their capacity for reducing estimation errors when given immediate or delayed feedback of actual blood glucose was examined. The results showed that neither delayed nor immediate feedback produced a significant improvement in the mean estimation accuracy of these groups of patients or in their ability to predict whether their blood glucose was in the acceptable or unacceptable range. Patients were particularly inaccurate in detecting Low [less than 4.0 mmol/L (less than 72.0 mg/dl)] and Very High [greater than 16.0 mmol/L (greater than 288.0 mg/dl)] blood glucose levels. Examination of mood-blood glucose relationships revealed consistent patterns for individual subjects and considerable differences between subjects.

Orbital decompression.

A new technique for exposure of the orbit for decompression of the orbit is described. It may be used for other purposes such as orbital fracture repair, orbital exploration for tumors in the inferior orbit, or reconstruction of the orbit by a variety of methods. The technique provides ready, broad exposure. The approach also avoids not uncommon complications of the eyelid, approaches to the orbit such as skin shrinkage and ectropion of the lower lid. It also results in minimal cosmetic deformity.

Exposure of the inferior orbit with fornix incision and lateral canthotomy.

Exposure of the inferior orbit is necessary for exploration of the orbit for repair of orbital fractures, reconstruction of the orbit to correct enophthalmos with a volume implant, and decompression of the orbit to relieve the symptoms and improve appearance in cases of dysthyroid exophthalmos. The usual approach to the inferior orbit has been through a subciliary skin incision and dissection of a skin flap to the orbital rim. A technique is presented which utilizes an inferior fornix conjunctival incision combined with a lateral canthotomy and outward rotation of the lower lid. The advantages of this technique are that it avoids a lengthy skin incision with dissection which may present skin shrinkage if repeated surgery is necessary, employs a very simple closure, and provides better exposure of the nasal, inferior and lateral orbits while leaving the lower lid structures intact, preserving its integrity.
