Condividere il sapere creativo di Giacomo Verde. Dall’archivio documentale all’archivio empatico. Anna Maria Monteverdi intervista Gabriele Coassin
No full textPatrimoni a rischio sono quegli archivi audiovisivi anni Ottanta (anche di natura tea-trale) non ancora censiti nella loro completezza e che in alcuni casi, necessitano di restauro a fini di conservazione e valorizzazione dei contenuti. dedicato tutta la sua vita alla produzione, all’archiviazione e restauro di materiali d’arte audiovisivi e infine, all’insegnamento; il suo laboratorio (un vero e proprio “museo storico del video”) ha ancora macchine antiche infunzione (116 videoregistratori, 90 proiettori, 74 registratori audio, 138 macchine fotografiche di tutte le epoche) grazie alla costante manutenzione, perfettamente in grado di leggere e duplicare formati oggi obsoleti, di dif-ficile reperibilità anche per Mediateche regionali. Interviene su VHS e Super VHS, video 8, Hi 8, U-Matic -BVU, Betamax, Betacam, Video 2000 per digitalizzarli e acquisire i contenuti prima che questi vadano irrimediabilmente perduti2. Si rivolgono al suo laboratorio Gallerie d’Arte e Musei nazionali non solo per il recupero dei nastri “offesi” dal tempo e dagli sbalzi di temperatura, ma anche per mettere in mostra audiovisivi originali degli anni Settanta e Ottanta che necessitano di lettori non più in uso. A lui dobbiamo anche laproduzione di alcune delle prime opere di video arte di Giacomo Verde con il quale aveva stretto una grande amicizia all’epoca della residenza veneta di Verd
One-port vs. three-port diagnostic vitrectomy for posterior segment diseases of unknown origin
No full textPurpose: To compare the safety and the effectiveness of one-port vs. three-port diagnostic vitrectomy in undiagnosed cases of posterior segment inflammation.
Methods: We retrospectively collected data from 80 consecutive diagnostic vitrectomies performed using a one-port (n = 40) or a three-port approach (n = 40). Cases of suspected postoperative endophthalmitis were not included in the study. Several variables were compared among groups, including length of surgery, postoperative best-corrected visual acuity (BCVA), diagnostic success and surgical complications.
Results: The mean duration of surgery was shorter in the one-port group when compared to the three-port group (15 ± 8 min vs. 49 ± 30; p = 0.0001). The patients were observed for a mean follow-up of 19 months (range 1-84). In the one-port group, the mean BCVA improved from 1.31 ± 0.96 to 0.57 ± 0.59 logarithm of minimum resolution (LogMAR) (p = 0.0009). In the three-port group, BCVA improved from 0.98 ± 0.76 to 0.51 ± 0.76 LogMAR (p = 0.0005). The difference in mean postoperative BCVA between groups was not significative at the last follow-up. One-port vitrectomy yields to a final diagnosis in 80% of the cases, and three-port vitrectomy in 48%. Most of the one-port vitrectomies were carried out under topical anesthesia. After surgery, in both groups three eyes developed a retinal detachment.
Conclusions: In this pilot study, the one-port diagnostic vitrectomy has proven to be as effective and safe as the three-port approach, allowing a reduction in surgical times. One-port diagnostic vitrectomy might be considered as the first option for those cases where more complex surgical procedures are not needed

Influence of the Renin Profile on the Blood Pressure Response to Different Doses of Hydrochlorothiazide plus either Quinapril or Captopril
No full textThe antihypertensive efficacy and safety of quinapril 20mg plus hydrochlorothiazide 6.25mg were compared over 8 weeks with Captopril 50mg plus hydrochlorothiazide 15mg in 52 patients with mild to moderate essential hypertension (27 men and 25 women age 49.7 ±8.4 years). The study also evaluated the relationship between antihypertensive efficacy and plasma renin activity/blood pressure sensitivity to changes in dietary sodium intake. The combination of quinapril or Captopril with hydrochlorothiazide showed similar antihypertensive effects and tolerability. Neither blood pressure salt sensitivity nor renin profile were predictive of blood pressure response to either therapy. These results suggest that the antihypertensive efficacy of an angiotensin converting enzyme inhibitor when administered in fixed ratio with a thiazide diuretic is independent of salt sensitivity in hypertension. © 1994, Adis International Limited.
