Correlations between BMD data obtained with spiral CT and standard quantitative CT were highly significant. By using a conversion factor, BMD measurements can be determined with routine abdominal spiral CT scans.

37 patients with clinically and radiologically proved reflex sympathetic dystrophy syndrome were scintigraphed by 99mTc-MDP (three-phase-scintigraphy). In 87% of the examinations (all three-phases) an increased tracer accumulation in the region of the affected limb could be seen scintigraphically. The majority of the positive results (92% resp. 87%) were found in the interval phase (phase II) and the late phase (phase III) of the scintigraphic examinations.--We recommend a staging of the increase of the tracer accumulation when examining the reflex sympathetic dystrophy syndrome. This staging doesn't significantly correlate with the familiar clinical and radiological stagings. However it may be useful when assessing the course of the syndrome.--Increased tracer accumulations could be observed in the case of clinically, radiologically and scintigraphically manifest reflex sympathetic dystrophy syndrome in the region of the foot, frequently in the ipsilateral knee region, rarely in the ipsilateral hip joint region, although clinically the syndrome could not be observed in these regions.

The process of chronic hypophosphatemic vitamin D-resistant rickets--observation of two cases. With the male patient--our first case--the disease was sporadic and had not been recognized for a long time. In his early adulthood it manifested itself as Umbauzonen (pseudofractures) in the larger context of active osteomalacia. It was possible to observe the pseudofractures before and while the patient was treated with drugs. High doses of vitamin D 3 and dosage of phosphate mitigated the complains although with respect to the radiological, scintigraphic, humoral and histological findings there was only slow improvement or no improvement at all.--The patient's daughter is affected by the disease as well. In her case the pathological signs of her bones became better when treated with vitamin D 3.
