Preretinal partial pressure of oxygen gradients before and after experimental pars plana vitrectomy.

PURPOSE: To evaluate preretinal partial pressure of oxygen (PO2) gradients before and after experimental pars plana vitrectomy. METHODS: Arteriolar, venous, and intervascular preretinal PO2 gradients were recorded in 7 minipigs during slow withdrawal of oxygen-sensitive microelectrodes (10-μm tip diameter) from the vitreoretinal interface to 2 mm into the vitreous cavity. Recordings were repeated after pars plana vitrectomy and balanced salt solution (BSS) intraocular perfusion. RESULTS: Arteriolar, venous, and intervascular preretinal PO2 at the vitreoretinal interface were 62.3 ± 13.8, 22.5 ± 3.3, and 17.0 ± 7.5 mmHg, respectively, before vitrectomy; 97.7 ± 19.9, 40.0 ± 21.9, and 56.3 ± 28.4 mmHg, respectively, immediately after vitrectomy; and 59.0 ± 27.4, 25.2 ± 3.0, and 21.5 ± 4.5 mmHg, respectively, 2½ hours after interruption of BSS perfusion. PO2 2 mm from the vitreoretinal interface was 28.4 ± 3.6 mmHg before vitrectomy; 151.8 ± 4.5 mmHg immediately after vitrectomy; and 34.8 ± 4.1 mmHg 2½ hours after interruption of BSS perfusion. PO2 gradients were still present after vitrectomy, with the same patterns as before vitrectomy. CONCLUSION: Preretinal PO2 gradients are not eliminated after pars plana vitrectomy. During BSS perfusion, vitreous cavity PO2 is very high. Interruption of BSS perfusion evokes progressive equilibration of vitreous cavity PO2 with concomitant progressive return of preretinal PO2 gradients to their previtrectomy patterns. This indicates that preretinal diffusion of oxygen is not altered after vitrectomy. The beneficial effect of vitrectomy in ischemic retinal diseases or macular edema may be related to other mechanisms, such as increased oxygen convection currents or removal of growth factors and cytokines secreted in the vitreous.

Posada en funcionament d'una oficina de tramitació ràpida (OTRA) de la Direcció General d'Indústria, del Govern de les Illes Balears

La Direcció General d’Indústria té com a principal finalitat el control de les instal•lacions i de diferents activitats de l’àmbit industrial; exerceix aquesta funció mitjançant la tramitació de documentacions tècniques i la inspecció. Com tota Administració Pública, es troba en un entorn molt dinàmic, on només les empreses més competitives poden subsistir i els ciutadans tenen noves necessitats molt diferents de les de fa un temps. Ambdós, empreses i ciutadans, exigeixen serveis de qualitat a un sector públic que no té altra alternativa que caminar en la mateixa direcció. L’objectiu d’aquest treball és planificar una sèrie d’accions estratègiques que permetran la millora dels serveis oferts a fi de complir amb les expectatives de la ciutadania. S’ha realitzat una anàlisi interna i de l’entorn de l’organització, el resultat de la qual ha estat la detecció d’una sèrie de punts de millora. A continuació s’ha definit una pla operatiu de qualitat, emmarcat dins del segon Pla Estratègic de Qualitat del Govern de les Illes Balears, amb tres propostes d’actuació: la separació de funcions, la tramitació ràpida d’expedients i el pla de formació. Les propostes esmentades constitueixen les bases d’una nova unitat orgànica (Oficina de Tramitació Ràpida), el model organitzatiu de la qual queda definit en els diferents apartats del treball. Igualment, s’hi descriu el procés de posada en funcionament dels distints procediments que es vagin adaptant al nou sistema i la planificació dels treballs a dur a terme, que seguiran el cicle de la qualitat de Deming, és a dir, planificar, fer, verificar i actuar.
