Highly sensitive dynamic strain measurements by locking lasers to fiber Bragg gratings.

A novel, sensitive, simple, and robust strain interrogation technique is analyzed and experimentally tested. By locking a laser wavelength to the midreflection wavelength of a standard fiber Bragg grating and measuring the error signal, we achieve high dynamic strain sensitivity of 45 picostrain/ radicalHz rms at 3 kHz, where the dominant noise in the experiment is the laser frequency noise.

Short-term tolerance of pulse methylprednisolone therapy in patients with diabetes mellitus.

Purpose: To assess the short-term tolerance of pulse methylprednisolone in patients with diabetes.

Design: Retrospective study in a national eye center.

Participants: Eighty patients with type 2 diabetes, half of them also treated for hypertension, who received 3-day pulse methylprednisolone between January 1999 and December 2002 for eye disorders and were monitored according to a written protocol.

[Glucose tolerance of high-dose intravenous methylprednisolone therapy in ophthalmology].

Introduction: Short-term, high-dose intravenous methylprednisolone therapy, also called pulse methylprednisolone, is widely used in a variety of inflammatory eye diseases. Monitoring blood glucose during this therapy is recommended. We evaluated the clinical implications of glycemia monitoring during repeated pulse methylprednisolone for eye disease.

Intravenous pulse methylprednisolone therapy in eye disease: effect on glucose tolerance.

Purpose: To determine which subjects need close glycemic monitoring during intravenous pulse methylprednisolone therapy for eye disease.

Design: Retrospective study in a national eye center.

Participants: Two hundred twenty-four subjects who received over a one-year period 250 to 1000 mg daily intravenous methylprednisolone over 3 consecutive days for ophthalmologic conditions.

[Thyroid orbital pathologies in ophthalmological settings].

Objective: To illustrate the originality and diversity of an ophthalmologic pathology associated with a thyroid disease (OATD), we report 42 cases of patients hospitalised or having consulted an ophthalmologic department for this disease over a period of 4 years.

Method: Each patient was assessed by an endocrinologist and an ophthalmologist. Data included the OATD severity score, date of occurrence compared with the thyroid disease and determination of thyroid function and immune abnormalities.
