PURPOSE To describe 7 cases of unilateral, chronic and/or recurrent anterior uveitis caused by cytomegalovirus (CMV) in immunocompetent patients; to identify specific ophthalmologic characteristics; and to evaluate the clinical effect of valganciclovir treatment. DESIGN Retrospective observational case series. PARTICIPANTS Immunocompetent patients (n =(More)
A controlled group study involving 12 patients was performed with the purpose of comparing the effects of EMG feedback in the (re-)learning of motor control to the effects of a conventional physical therapy procedure (NDT). The therapy was focussed on the improvement of the dorsiflexion function of the foot. Special attention was given to the measurement(More)
OBJECTIVE Graves' ophthalmopathy (GO) and Graves' hyperthyroidism are closely associated diseases and thought to be caused by the same autoimmune process. An obvious explanation for this would be the presence of autoantibodies reacting with an autoantigen present in the orbit and the thyroid gland. The TSH-Receptor (TSH-R) antibodies are a likely candidate,(More)
In chronic hypoxemia blood flow and oxygen supply to vital organs are maintained, but to nonvital organs they are decreased. We measured organ blood flows (microspheres) and whole blood viscosity in 10 chronically hypoxemic lambs, with an atrial septal defect and pulmonary stenosis, and in 8 control lambs. Vascular hindrance (resistance/viscosity) was(More)
Adhesion molecules play a key role in autoimmune disorders, and serum concentrations of soluble adhesion molecules are increased in Graves' ophthalmopathy (GO). Whether this is due to the strong association with smoking is unknown. It is also not known if the severity or activity of GO determine the serum levels of adhesion molecules. We measured serum(More)
Increased serum cytokine levels have been reported in patients with autoimmune thyroid disease, but less is known about their levels in patients with Graves' ophthalmopathy (GO). It is not known whether GO is a cell-mediated or humoral autoimmune disease. We investigated whether serum cytokines are elevated in GO patients and whether the cytokines were Th1-(More)
We have measured the amplitude of ocular counterrolling (OCR) and the change in vertical deviation in the Bielschowsky head-tilt test (BHT) in 23 cases of unilateral superior oblique palsy. OCR was measured with a photographical method, using limbal, conjunctival vessels as landmarks. Average OCR of the healthy eye was 5.4 +/- 2.4 (SD) deg either side, at(More)
In patients with massive pulmonary embolism threatened by haemodynamic instability, thrombolytic treatment is recommended. But when it fails, therapeutic options remain limited and are mainly guided by local expertise. In the current case, we report a potential treatment modality for this situation. A 60-year-old male patient collapsed several times at(More)
