Thermograpic study of upper extremities in patients with cerebral palsy

Lampe R., Kawelke S., Mitternacht J., Turova V., Blumenstein T., Alves-Pinto A.

Trophic disorders like reduced skin blood circulation are well-known epiphenomenon of cerebral palsy (CP). They can influence quality of life and can lead to skin damages and, as a consequence, to decubitus. Therefore, it is important to analyse temperature regulation in patients with CP. Thermal imaging camera FLIR BCAM SD was used to study the dependency of skin blood circulation in upper extremities of patients with CP on hand dominance, hand force and hand volume. The hand force was evaluated using a conventional dynamometer. The hand volume was measured with a volumeter. A cold stress test for hands was applied in 22 patients with CP and 6 healthy subjects. The warming up process after the test was recorded with the thermal camera. It was confirmed that the hands of patients warm up slower comparing to healthy persons. The patients’ working hands warm up faster than non-working ones. A slight correlation was established between the hand grip force of the working hands and their warm up time. No correlation was found between the warming up time and the volume of the hand. The results confirm our assumption that there is a connection of peripheral blood circulation to upper limb motor functions.

The Holocene sea level rise in the Southern Baltic as reflected in coastal peat sequences

Lampe R., Janke W.

Polish Geological Institute Special Papers

Vol. 11

Coastal peatlands depend in respect to their vertical growth totally on the sea level, are witnesses of its variations and, furthermore, preserve remnants of organisms which permit conclusions about the nutrient content and salinity of the flood water and thus of the surrounding sea. Black layers which occur frequently in the peat profiles point to evolution phases whereas the sea level fell or the mire became desiccated. Around thirty radiocarbon data, data from pollen and diatom analyses as well as from geochemical investigations provide the base to reconstruct the sea level history. The placement of particular transgression/regression stages could be determined with a higher accuracy than before and demonstrate a strong correlation to climate oscillations such as to the Late Bronze Age dry period or the Little Ice Age climate deterioration. Uncertainties still remain in regard to the regression magnitudes and to the length of the hiatuses in the peat sequences.
