[Possibility of early diagnosis of diabetic nephropathies].

The serum and urine level of beta-2-microglobulin was examined by the authors in different stages of nephropathy of 250 patients suffering from diabetes mellitus (I type 178 pts, II type 72 pts). Beta-2-microglobulin values measured in diabetic patients without renal microangiopathy did not show any difference compared with that of the controls. In patients with freshly discovered diabetes mellitus significantly decreased beta-2-microglobulin levels were found, probably due to the increased glomerular filtration rate.

Fluoroangiographic picture of the acute stage of the retinal lesion in subacute sclerosing panencephalitis.

The fluoroangiographic examination of the acute stage of retinal lesion in a 16-year-old girl suffering from SSPE showed an exclusively localized retinal vascular involvement 4 days after the onset of her visual complaints. A week later this occlusive vascular lesion progressed to a large area of capillary bed obstruction and it was followed up angiographically. The choroid was involved even during the late stages of evolution of retinal lesion at a low degree.

[Binocular inferior altitudinal hemianopia following occult hemorrhage (author's transl)].

Authors report a case of binocular inferior altitudinal hemianopia caused by occult haemorrhage from the gastrointestinal tract. There was a 36 hours' period between the onset of visual field defects of the two eyes. The ocular signs have thrown light on the grave anaemic condition.
