    Notes: Summary We report on incidental findings during family screening of two kindreds with multiple endocrine neoplasia type IIa. Pheochromocytoma and medullary thyroid carcinoma of considerable size were detected. The results underline the importance of early diagnosis of the syndrome, since the afflicted may be almost or wholly asymptomatic. High resolution chromosome banding studies were carried out in both families, but no abnormality was found. Linkage analysis using DNA markers closely related to the chromosomal locus at chromosome 10 was carried out and was positive in two asymptomatic offspring of one family, whereas the markers were not informative in a second family. We recommend early linkage analysis for establishing the genetic status in offspring of multiple endocrine neoplasia type IIa families to identify for further screening those who are predicted to be gene carrier.

    The short-term fixation of radiopharmaceuticals in bone (1979)
    Springer
    European journal of nuclear medicine 4 (1979), S. 423-428

    Notes: Abstract The relationship between local blood flow and bone clearance of 18 F, 32 P-P (orthophosphate), 32 P-PPi (pyrophosphate), 45 Ca, 85 Sr, 99mTc- and 113 Sn-EHDP was evaluated in the non-adult rat. During one single blood passage nearly 100% of 18 F was extracted in the femoral diaphysis, the extraction efficiency for the other radiopharmaceuticals was about 40%. Blood flow and bone clearance was higher and the extraction efficiency lower in the distal femoral epiphysis including the growth plate. The short-term bone uptake of 32 P-P was lowered considerably by the simultaneous application of inactive orthophosphate, whereas the bone uptake of 32 P-PPi was not suppressed. It is suggested that the rapid deposition of radiopharmaceuticals in bone is not caused by an ionic exchange process on crystal surfaces of already existing mineral but is due to an ionic exchange during the precipitation of calcium phosphate in the calcifying bone matrix. Only 18 F is exchanged with hydroxyl groups of already precipitated hydroxyapatite, whereas the calcium and phosphate ions in the precipitated hydroxyapatite are not further accessible to an exchange process.

    Relationship between blood flow and radiostrontium uptake in the healing bone fracture (1979)

    Notes: Abstract The healing of a diaphyseal tibia fracture was followed in the rat. Callus formation, blood flow and Sr-85 uptake were assessed by a ratio comparison of the fractured to the contralateral side. No correlation was found between blood flow and Sr-85 deposition in the callus and the adjacent bone of the same extremity. It is concluded that the deposition of a radiopharmaceutical in bone is primarily related to the presence of calcifiable organic bone matrix and only secondarily to the bone formation rate and to variations in the local blood flow.

    Description / Table of Contents: Zusammenfassung Von 1980–1985 wurden 1839 Patienten mit Schilddrüsenknoten untersucht. Sonographisch wiesen 98 % der Strumaknoten echoarme oder komplexe Strukturen auf. Bei 85 % war die Radionuklidspeicherung herabgesetzt, 10 % (n = 182) waren cytologisch positiv oder suspekt. Von diesen 182 Patienten wurden 60 operiert und 122 regelmäßig nachuntersucht. Bei 35 der 60 operierten Patienten konnte histologisch ein Schilddrüsencarcinom nachgewiesen werden. Die Kombination von echoarmer Raumforderung, szintigraphisch kaltem Knoten und cytologisch positivem oder auch nur suspektem Befund erfordert dringend die Operation.
    Notes: Summary From 1980 to 1985 1,839 patients with thyroid nodules were investigated. 98 % of them showed ultrasonic patterns of either echo-poor or complex structures, 85 of the nodules were scintigraphically cold, in 10% (n = 182) cytological findings were positive or at least suspect. Of these 182 patients 60 underwent operation, whereas 122 were followed up continuously. In 35 of 60 patients operated histological examination confirmed thyroid carcinomas. The combination of echo-poor, cold nodules and cytological positive or suspect findings urgently requires operation.

    Description / Table of Contents: Zusammenfassung Von 1960–1983 wurden 423 Patienten mit Schilddrüsencarcinomen behandelt. Bei folliculären, medulldren und anaplastischen Carcinomen wurde die Thyreoidektomie angestrebt. Die Hemithyreoidektomie mit Keilexcision der gesunden Seite erfolgte beim papillären Carcinom mit einseitigem Befall. Nach Thyreoidektomie wurde die Hormontherapie durchgeführt. Anaplastische Carcinome wurden postoperativ extern bestrahlt. Die Zehnjahresüberlebensraten betrugen beim folliculären Carcinom ohne Metastasen 65%, mit Metastasen 30%, beim papillären Carcinom ohne Metastasen 90%. Nur 50% der Patienten mit medullarem Carcinom überlebten 5 Jahre. Beim anaplastischen Carcinom starben 80% innerhalb von 6 Monaten.
    Notes: Summary From 1960 to 1983, 423 patients with thyroid carcinoma were treated. In follicular, medullary, and anaplastic carcinomas, thyroidectomy was carried out where possible. Hemithyroidectomy with wedge excision of the healthy side was performed in unilateral papillary carcinoma. After thyroidectomy, hormone therapy was given. Anaplastic carcinomas were postoperatively irradiated externally. The 10-year survival rates were 65% in follicular carcinoma without metastases, 30% in follicular carcinoma with metastases, and 90% in papillary carcinoma without metastases. Only 50% of the patients with medullary carcinoma survived for 5 years. Among anaplastic carcinoma cases, 80% died within 6 months.
