[Near infrared spectroscopy: a noninvasive optical method for monitoring cerebral oxygenation and hemodynamics]. / Spektroskopia w bliskiej podczerwieni--nieinwazyjna metoda optyczna monitorowania oksygenacji i hemodynamiki mózgu.

The Near Infrared Spectroscopy (NIRS) has been established as a non-invasive method for monitoring the oxygenation state of human brain at the bedside. This possible by observing spectral changes in the tissue caused by presence of oxygenated hemoglobin, deoxygenated hemoglobin and cytochrome aa3. In this paper the technical data of the NIRS instrument and its clinical application particularly in investigation of cerebral oxygenation and hemodynamic has been described.

[2 cases of Sneddon syndrome]. / Dwa przypadki zespolu Sneddona.

Two cases of Sneddon syndrome (S.s.) in a 33 and 53-year-old women who developed arterial hypertension, cerebral ischaemic signs and who have livedo reticularis or livedo racemosa, are reported. The authors describe clinical, radiological and biological features of this rare disease, as well as diagnostic investigations including the measurements of the antiphospholipid antibodies (APA). The possible role of APA in the pathogenesis of S.s. is discussed.
