Li Fioretti di Sancto Francesco
No full textIl grande pannello, realizzato nel 1940 dal Laboratorio Artigiano Triestino su disegno di Anita Pittoni, venne esposto per la prima volta alla VII Triennale Internazionale d’Arte decorativa e fu il frutto del concorso indetto dall’Ente Triennale di Milano e dall’Enapi di Roma (il cui scopo era quello di indurre gli artisti a fornire disegni moderni d’arte applicata alle scuole e ai laboratori femminili di ricamo e merletto). Il concorso prevedeva che vi partecipassero 19 tende da esporre alle finestre dell’emiciclo del Palazzo delle Arti. Il tema risultava libero, uniche direttive da seguire: misure e tecniche. Anita Pittoni decise di illustrare in 8 riquadri la vita di San Francesco. Il manufatto reca iscrizioni in volgare umbro accompagnate da raffigurazioni dal carattere primitivo. Il risultato fu ottimale tant’è che il lavoro si aggiudicò la medaglia d’oro per il disegno e una menzione d’onore per il suo contributo all’Enapi. Alla Pittoni si deve l’invenzione di una nuova interpretazione delle tecniche della maglia e dell’uncinetto, usate sino ad allora per realizzare principalmente pizzi e merletti. Furono da lei adoperate per realizzare sofisticati tessuti d’arredamento. Alla mostra degli artisti triestini alla Permanente di Milano la Pittoni presentò, oltre al grande pannello, anche vari oggetti di moda femminile quali costumi per la spiaggia, mantelli, un abito estivo di rete gialla, una giacca di canapa, un costume da sera in rame, borsette, bandoliere, bottoni, tappeti ed altri accessori. Ciò che colpì delle creazioni di Anita fu la constatazione che era un’artista capace di creare forme e ritmi tessendo filati come altri usavano parole e suoni. Le parti figurative sono accompagnate da scritte ricamate che riportano alcuni passi tratti dai Fioretti di San Francesco. Nel primo riquadro si legge una parte tratta dal Capitolo 9 in cui San Francesco, essendo con fra Lione in un luogo dove non avevano libri e breviario col quale recitare le preghiere del mattutino, i due si accordarono affinché Fra Lione ripetesse quanto San Francesco diceva. San Francesco iniziò così: “O Signore mio del cielo e della terra, io ho commesso contro a te tante iniquità e tanti peccati, che al tutto son degno d’esser da te maledetto”. E frate Lione anziché rispondere come Francesco gli aveva indicato rispose con la frase ricamata sul pannello: “O frate Francesco, Iddio ti farà tale, che tra li benedetti tu sarai singolarmente benedetto”. Accanto a questa frase si può ammirare il ricamo decorato in cui San Francesco viene elevato da due figure angeliche. La grande tenda presenta una decorazione “a scacchiera”: alla parte scritta corrisponde una formella decorata e viceversa per quattro fasce orizzontali. Il ritmo delle due colonne è ulteriormente scandito dalla realizzazione, in senso verticale, di una sorta di rima incrociata (ABAB). La seconda formella illustra un passo tratto dal 16° Capitolo dei Fioretti in cui San Francesco, accogliendo gli inviti di Santa Chiara e San Silvestro di predicare a quante più genti possibili, iniziò a predicare anche agli uccelli. La terza formella scritta riprende nuovamente parte del Capitolo 9 caratterizzata dallo scambio di battute tra San Francesco e San Lione. Nella parte iconografica invece ritroviamo San Francesco circondato da fiori. Gli ultimi due riquadri, trattano un passo del 15° capitolo dei Fioretti. Quello illustrato a sinistra, si vede San Francesco in saio con di fronte Santa Chiara. La formella è impreziosita da un decoro, nella parte superiore, a motivo a stella, mentre nella parte inferiore, vi è un motivo decorativo floreale con degli uccellini. La parte scritta chiude invece il pannello decorativo nel quale sono riportate le parole di santa Chiara: “ed ella come figliuola di santa obbidienza avea risposto: “Padre, io sono sempre apparecchiata ad andare dovunque voi mi manderete”. Acquistato dall’Università degli Studi di Trieste nel 1951 è attualmente visibile nell’aula Magna della sede principale dell’Università.Pannello a velo, ricamo su tulleFirmato in basso a destra “Anita Pittoni”Edificio Centrale, Aula Magn

Respiratory depression following administration of low dose buprenorphine as postoperative analgesic after fentanyl balanced anaesthesia
No full textOpioids are among the most ancient and widely used drugs in anaesthesiology. The pharmacology of opioid analgesics and their receptors is a complex and not fully understood matter; even more complex are the interactions between different classes of opioids at both molecular and clinical levels. We want to report here a clinical observation to emphasize the importance of the theoretical basis of anaesthesiology. This paper contains a clinical observation of respiratory depression following the administration of buprenorphine as postoperative analgesic after balanced anaesthesia with fentanyl. The observed case is interpreted in the light of the pharmacokinetics and pharmacodynamics of the different classes of opioid drugs (agonists, agonists-antagonists, antagonists) and of the interactions with their respective receptors

No full textSpinal anesthesia in outpatient knee surgery: 22-Gauge versus 25-gauge sprotte needle
No full textSpinal anesthesia in day-care surgery is still controversial because of the possibility of postdural puncture headache (PDPH). The use of the Sprotte needle with a conical tip that spreads the dural fibers may reduce the incidence of PDPH. The aim of this study was to compare the 22-gauge and 25- gauge Sprotte needles with respect to PDPH and postoperative complaints in outpatients undergoing arthroscopy. The rate of spinal anesthesia failure and the feasibility of unilateral spinal anesthesia when using a low dose of anesthesia was also verified. For this randomized, prospective study, 234 patients undergoing elective arthroscopy were chosen. Patients were allocated randomly to have spinal anesthesia with either a 22-gauge or 25-gauge Sprotte needle. Dural puncture was performed with the patient in a lateral flexed decubitus position. After the injection of anesthetic solution (0.5-1.2 mL of 1% bupivacaine in 8% glucose) patients remained in the lateral decubitus position for 30 min. ..

Relationship between central venous pressure and bioimpedance vector analysis in critically ill patients
No full textOBJECTIVE: To assess the relationship between central venous pressure values and bioelectrical impedance vector analysis (BIVA), which may be used as complementary methods in the bedside monitoring of fluid status. DESIGN: Cross-sectional evaluation of a consecutive sample. SETTING: Intensive care unit of a university hospital. PATIENTS: One hundred and twenty-one consecutive Caucasian, adult patients of either gender, for whom routine central venous pressure measurements were available. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Central venous pressure values and impedance vector components (i.e., resistance and reactance) were determined simultaneously. Total body water predictions were obtained from regression equations according to either conventional bioimpedance analysis or anthropometry (Watson and Hume formulas). Variability of total body water predictions was unacceptable for clinical purposes. Central venous pressure values significantly and inversely correlated with individual impedance vector components (r2 = .28 and r2 = .27 with resistance and reactance, respectively), and with both vector components together (R2 = .31). Patients were classified in three groups according to their central venous pressure value: low (0 to 3 mm Hg); medium (4 to 12 mm Hg); and high (13 to 20 mm Hg). Three BIVA patterns were considered: vectors within the target (reference) 75% tolerance ellipse (normal tissue hydration); long vectors out of the upper pole of the target (dehydration); and short vectors out of the lower pole of the target (fluid overload). The agreement between BIVA and central venous pressure indications was good in the high central venous pressure group (93% short vectors), moderate in the medium central venous pressure group (35% normal vectors), and poor in low central venous pressure group (10% long vectors). CONCLUSIONS: Central venous pressure values correlated with direct impedance measurements more than with total body water predictions. Whereas central venous pressure values >12 mm Hg were associated with shorter impedance vectors in 93% of patients, indicating fluid overload, central venous pressure values <3 mm Hg were associated with long impedance vectors in only 10% of patients, indicating tissue dehydration. The combined evaluation of intensive care unit patients by BIVA and central venous pressure may be useful in therapy planning, particularly in those with low central venous pressure in whom reduced, preserved, or increased tissue fluid content can be detected by BIV
Anti-beta 2-glycoprotein I antibodies bind to central nervous system.
No full textAnti-beta 2-GPI antibodies (a beta 2-GPI) were found in serum from patients with anti-phospholipid syndrome (APS) and/or systemic lupus erythematosus (SLE). Since a beta 2-GPI are often found in patients with anti-cardiolipin antibodies (aCL), their role in thrombosis as well as other central nervous system (CNS) manifestations in APS is unclear. We, therefore, investigated whether affinity-purified a beta 2-GPI bind the CNS. Astrocyte and neuron cell lines and histological sections were used as CNS substrates. Indirect immunofluorescence and/or streptavidin-biotin-peroxidase techniques revealed that astrocytes, neurons and vascular endothelium were bound by purified a beta 2-GPI (mouse monoclonal, rabbit polyclonal, human serum Ig a beta 2-GPI). This suggests a potential role for a beta 2-GPI in the CNS damage, as a beta 2-GPI might contribute to CNS pathology by either a direct interaction with astrocytes and neurons or an interaction with cerebral vascular endothelial cells. CNS immunoreaction was also demonstrated using six a beta 2-GPI-positive sera from patients (four with neurological manifestations). No binding to CNS was seen using a beta 2-GPI-negative sera, i.e. five from SLE patients (two with CNS involvement) and six healthy donors, or a monoclonal aCL without a beta 2-GPI immunoreactivity. Thus, the CNS reactivity by the a beta 2-GPI-positive sera appears specifically due to a beta 2-GPI and independent from aCL. Because of the presence of aCL in all patient sera, and the CNS involvement in three control patients, it is not possible to attribute a direct role for a beta 2-GPI in neurological diseases in this study
