Knochenbefunde bei Psoriasis
Unter 40 mit der Ganzkorperscintigraphie (Technetium-Diphosphonat) untersuchten Psoriatikern fanden sich bei 3 Patientinnen diffuse und umschriebene pathologisch gesteigerte Nuklidanreicherungen im Schadelskelet. Diese gelenkfernen Proliferationszeichen im Knochenbereich weisen ebenso wie der gegenuber dem Gelenkscan haufiger positive Knochenscan auf eine Fruhbeteiligung des knochernen Skelets bei Psoriasis hin.
First experiences with a high-resolution ultrasonic scanner in the diagnosis of malignant melanomas
The use of high-resolution ultrasonic instruments with transducer frequencies above 8 MHz makes it possible to visualize malignant melanomas of a thickness of more than 0.7 mm. While the sonolucent structure has not permitted the dignity of a lesion to be judged to date, it is easy to determine the maximal tumor thickness as well as infiltration of the subcutis. Thus "low-risk" and "high-risk" melanomas may be differentiated preoperatively according to these parameters. The results are of great use for the operator to plan the extent of his intervention, as well as to select patients for prophylactic regional lymphonodectomy.
Joint involvement in psoriasis.
21 unselected hospital patients with psoriasis (7 female, 14 males) were examined for joint lesions by clinical, roentgenological and scintigraphical methods (6 mCi99mTc-Pertechnetate, 4 mCi99mTc-Pyrophosphate). According to traditional concepts only 5 patients suffered from psoriatic arthropathy, in 8 other patients an extensive case history revealed some joint complaints.
