Twenty-one patients classified as “high-risk” problems were observed to assess fetal well-being, size, and growth with repeated plasma estriol and ultrasonographic measurements. Estriol levels were of value in the estimation of the fetal condition if fetal size and age were known. When serial plasma estriol measurements and ultrasonographic cephalometry are used together, the fetal well-being, size, and growth may be more accurately assessed and the risk of prematurity greatly reduced. Further combined studies are needed to clarify the relative values of estriol levels and ultrasonography in the assessment of fetal status. The cirteria of normal fetal growth and welfare in high-risk situations must be established in an effort to decrease high perinatal loss rates. 相似文献

Neurochemical imaging studies can identify molecular targets of abused drugs and link them to the underlying pathology associated with behaviors such as drug dependence, addiction and withdrawal. positron emission tomography (PET) is opening new avenues for the investigation of the neurochemical disturbances underlying drug abuse and addiction and the in vivo mechanisms by which medications might ameliorate these conditions. PET can identify vulnerable human populations, treatment strategies and monitor treatment efficacy. Thus, with this tool and the knowledge it provides, the potential for developing novel drugs and treatment strategies for drug addiction is now close at hand. 相似文献

ZusammenfassungFragestellung. Das Ziel dieser prospektiven Untersuchung bestand in dem Vergleich der Frühergebnisse von 2 verschiedenen Behandlungsstrategien bei diaphysären Klavikulafrakturen des Typs A und B der OTA-Klassifikation.Methoden. In der 1. Gruppe wurden 27 Patienten konservativ im Rucksackverband behandelt, in der 2. Gruppe wurde die Fraktur bei 26 Patienten minimal-invasiv mit einem elastischen Titannagel intramedullär geschient. In einem Zeitraum von 6 Monaten wurden die Ergebnisse der Behandlung zu 7 Zeitpunkten evaluiert.Ergebnisse. Während des gesamten Untersuchungszeitraums konnten signifikant bessere Ergebnisse hinsichtlich der Schulterfunktion, des Constant-Score, des DASH-Score, der subjektiven Zufriedenheit, der subjektiven Schmerzempfindung und des kosmetischen Ergebnisses festgestellt werden. Die Dauer der Arbeitsunfähigkeit war in der Gruppe der operierten Patienten um mehr als die Hälfte kürzer.Schlussfolgerung. Die elastisch stabile intramedulläre Osteosynthese der diaphysären Klavikulafraktur ist ein sicheres, minimal-invasives Verfahren, das funktionell und kosmetisch in der Frühphase nicht zu schlechteren Ergebnissen führt als die konservative Therapie mit dem Rucksackverband. 相似文献

Summary GFAP, Factor VIII/RAg, laminin, and fibronectin were immunohistochemically investigated in 15 glioblastomas and 15 gliosarcomas. GFAP was found variably positive in the glial areas. F VIII/RAg characterizes the endothelial cells and in gliosarcomas suggests the origin of the sarcomatous component from the endothelial proliferations. Laminin separates the two components and characterizes the inner and the outer basement membranes in the vessels. It is multiplied and thickened in endothelial proliferations, while it is often fragmented in the larger vessel wall proliferations. Our observations confirm that gliosarcoma represents the last stage of a process which starts with the endothelial hyperplasia of glioblastoma.Partially supported by CNR, Special Project Center, Grant no. 82.00410.96 相似文献

Prognosis and clinical varieties of ALS disease 总被引:1,自引:0,他引:1

210 cases of ALS disease in the period 1955–1979 are considered. Different parameters such as sex, age, duration and clinical
course have been correlated with four clinical types: conventional, pseudopolyneuritic, pyramidal and bulbar. The age distribution
shows a peak in the fifth decade of life. The sex ratio is 2.08∶1. Considering together all the clinical types, the mean duration
of the disease is 27.05 months. The bulbar variety has the poorest prognosis (19.6 months) and the pyramidal variety the best
(37.59 months). Familiarity is evidenced in only 3 cases. All our data are discussed and compared with those of the literature.
Sommario Sono stati considerati 210 casi di Sclerosi Laterale Amiotrofica nel periodo dal 1955 al 1979. Sono stati messi in relazione ai 4 tipi clinici della malattia: tipo convenzionale, pseudopolinevritico, piramidale e bulbare, vari parametri quali sesso, età, durata e decorso clinico. La distribuzione per età mostra un picco di incidenza nella 5a decade di vita. Il rapporto maschi/femmine è di 2,08∶1. La durata mediana di malattia per tutti i 4 tipi è di 27,05 mesi. La varietà bulbare ha la prognosi peggiore (19,6 mesi) mentre quella piramidale ha la prognosi migliore (37,59 mesi). Solamente in 3 casi è stata messa in evidenza una storia familiare. Tutti i nostri dati sono discussi e confrontati con quelli della letteraura.相似文献

The records of 65 consecutive patients discharged from the hospital with a diagnosis of primary parenchymal neoplasm of the kidney were reviewed. Four of the 65 patients had neoplasms which were not detected by excretory urography. The 4 undetected lesions included 3 renal cell carcinomas and 1 oncocytoma. All of these lesions projected from the anterior or posterior surface of the kidney, and all 4 were clearly demonstrated by computed tomography. Normal findings on an excretory urogram do not completely exclude a neoplasm of the kidney. When there is strong clinical suspicion of a renal neoplasm, computed tomography should be the initial examination or should be done even if the urogram has shown normal findings. 相似文献
