[Therapy and prognosis of hip fractures in psychogeriatric patients]. / Therapie en prognose van de heupfractuur bij psychogeriatrische patiënten.

In a retrospective study of 198 patients with fractures of the proximal femur from a defined population (i.e. all patients were living in a psychogeriatric nursing home) age, sex, type of fracture, type of treatment, psychiatric diagnosis, survival and mobility after the injury were analysed. We were able to demonstrate a positive association between the female sex and the prevalence of hip fracture. With regard to the type of fracture the occurrence of (per)trochanteric fracture was higher in men than in women; medial dial fractures were more frequent in women. Our findings suggested that in women with senile dementia operative treatment has better results with regard to survival. There was no association between type of operation and survival.

Phase fluorometer for measurement of picosecond processes.

Time-dependent fluorescence processes can be investigated using a phase fluorometer with variable frequency. The high cutoff frequency of 500 MHz leads to a time-resolving power of about 1 ps.
