99mTechnetium-Mercaptoacetyltriglycin (MAG3) zum Nachweis von Nierenveränderungen nach extrakorporaler Stoßwellenlithotripsie

1992

Extracorporeal shock wave lithotripsy (ESWL) has become the treatment of choice for urinary calculi. 117 patients were studied prospectively with 99mTc mercaptoacetyltriglycine (MAG3) before and after ESWL. 79 (66%) of the 119 kidneys treated had abnormal findings. Of these 63/119 (53%) had abnormal scans. 41 (65%) had focal lesions with a delayed intrarenal transport. The remaining 22 had a diffuse delay of intrarenal transport. A loss of relative renal function of 3% and more compared to the pretreatment values was observed in 50/119 (42%) patients. 99mTc MAG3 should be done routinely together with radiologic tests (CT or MRI) before and after ESWL to select the patients at risk for post …

Laparoscopic sentinel lymph node mapping and excision of the rectum using a radioactive tracer — a prospective experimental study

2009

Introduction: Patients with a low risk T1 rectal carcinoma can undergo the therapy of a local excision. In these patients the lymph node status remains unknown. There is a potential risk of up to 7% for nodal metastasis, in high risk cases it can rise up to 35%. To investigate the possibility of using the Sentinel lymph node (SLN) concept, which is anchored in the therapy of malignant melanoma and breast cancer, an experimental study on pigs was undertaken. The objective of the study was to laparoscopically identify and extract SLN’s from the rectum using a radioactive tracer (RT). Material und Methods: The experiment was conducted upon 30 pigs, because sample size calculation indicated tha…

99mTc–MAG3–Nierenfunktionsszintigraphie ohne und mit Captopril zur Diagnostik der renovaskulären Hypertonie

1993

In this study, the diagnostic value of renal function scintigraphy performed both without and with ACE inhibition has been evaluated using the new radiopharmaceutical 99mTc-MAG3. In cases of decompensated renal artery stenoses, the typical scan finding with this tubular excreted agent was shown to be a distinct parenchymal nuclide retention in combination with a delayed appearance of the radiotracer in the pelvic system. Using this criterion in 43 patients with suspected renovascular hypertension, sensitivity and specificity were 89 and 88%, respectively. Bilateral positive findings were non-specific; excluding them from the study, specificity increased to 100%. In renal insufficiency, capt…

Computertomographie nach extrakorporaler Stoßwellenlithotripsie (ESWL) der Nieren

1993

In 105 patients CT studies were done prospectively after renal ESWL with a second generation lithotripter. 33 (31%) of the patients had renal oedema (n = 8), renal (n = 20) or extrarenal (n = 31) bleeding. Three of the 23 patients who had a three year follow-up had chronic renal changes, 10 had renal stones. As blunt renal trauma can be the cause of renal hypertension a longterm follow-up is necessary in ESWL patients, particularly if there was renal bleeding after treatment. Further studies are needed to determine the exact risk of renal hypertension after ESWL.

Natura della tecnica e tecnica della natura

2015

Attraverso i 10 contributi che raccoglie, il volume tenta un'articolazione del rapporto fra natura e tecnica che è anche un attraversamento di alcuni passaggi cruciali della filosofia occidentale e che funge da ricostruzione del loro rapporto.

L'inquietudine dell'uomo fra prassi e tecnica

2017

The essay questions the relationship between prassi and techne in today's fully-tech society. The analysis moves from the aristotelian distinction between the various epistemai and continues through the comparison with the heideggerian idea of the root of knowing in the effectivity of existence, and with the gadameric perspective that highlights the similarities and differences between techne and praxis by bringing out at the same time the peculiarities of an irreducible knowledge of the technique.

Più che una lontana analogia. Psicoanalisi, techne e retorica greca.

2010

L'articolo si propone di mostrare la fecondità teorica della nozione greca di techne per la comprensione dello statuto epistemologico della psicoanalisi. Ripercorrendo la strada tracciata da Aristotele, vengono così indivduate le caratteristiche più significative della techne greca, una forma di sapere congetturale e fallibile, ma non per questo disinteressata alla verità, un sapere intrinsecamente orientato al fare che prevede una comprensenza di dimensione teorica e finalità produttiva. Su questo sfondo, il confronto si focalizza su una techne specifica, la retorica, che con la psicoanalisi condivide il riconoscimento del peculiare potere che le parole hanno nella vita degli uomini. É inf…

Socrate era un corruttore?

2007

Il socratico sapere di non sapere, riletto e individuato come rapporto tra piano teoretico e piano pratico (in Aristotele, Kant, Schelling)permette il rilievo di quel piano di assoluta alterità che compete propriamente alla libertà dell'uomo.

Semantica ed epistemologia di techne nella Grecia antica

2016

Sulla scorta del libro di Claude Calame intitolato "Prometeo genetista" e di cui l'A. ha curato parte della traduzione italiana, viene indagata l'ampia gamma di significati propri del termine greco "techne" e della corrispondente radice. La ricerca riguarda in particolare il valore semantico proprio del termine, che si contraddistingue, alla luce dell'analisi condotta sulle più antiche attestazioni nella letteratura greca sino al IV secolo a.C., come una vera e propria "vox media". Il carattere sostanzialmente medio del termine, evidente nell'uso linguistico di autori quali Eschilo e Sofocle, si connota più o meno positivamente a seconda della valutazione del singolo autore, e in primo luog…
