Efficacia di Buprenorfina/Naloxone nel trattamento delle tossicodipendenze: monitoraggio dei pazienti in terapia presso il Ser.T. di Marsala, ASL n. …

2018

Il lavoro sperimentale è stato eseguito nel periodo gennaio 2016-marzo 2017, presso il Ser.T. di Marsala dell’ASL n. 9 di Trapani, sotto la guida del Dott. Gaetano Gurgone e del Prof. Fabio Venturella, lavoro in cui sono stati altresì analizzati i dati relativi agli ultimi cinque anni. Il compito prevalente del Ser.T. è l’assessment, inteso come processo di raccolta, integrazione ed interpretazione delle informazioni.Si esplica attraverso: la diagnosi, la cura, la riabilitazione. Questo lavoro vuole essere quindi il resoconto di 15 mesi di osservazione su pazienti trattati con Buprenorfina/Naloxone,operando un confronto con pazienti trattati con il Metadone.Il campione è costituito da 32 so…

Neuronal and extraneuronal uptake and efflux of catecholamines in the isolated rabbit heart

1974

1. Isolated rabbit hearts were perfused with (−)-noradrenaline, (−)-adrenaline and (±)-isoprenaline for various time periods (1–180 min) and then washed with an amine-free medium. The venous concentration of the amine was estimated fluorimetrically during the infusion and after its end, to study removal and efflux, respectively. 2. In untreated hearts and after pretreatment with reserpine the removal had a constant rate over 20–60 min. After pretreatment with pargyline to block monoamine oxidase (MAO), however, the removal of noradrenaline declined exponentially to zero. Inhibition of the neuronal uptake (desipramine) and chemical sympathectomy (6-hydroxydopamine) abolished the removal of n…

Beta-adrenoceptor stimulation enhances transmitter output from the rat phrenic nerve.

1988

Abstract 1. Neurally-evoked output of newly synthesized [3H]-acetylcholine from the rat phrenic nerve was measured in the absence of cholinesterase inhibitors. 2. Noradrenaline and isoprenaline enhanced neurally-evoked transmitter output markedly. Moreover, immediately after the application of noradrenaline the basal tritium efflux increased significantly. 3. Pretreatment with propranolol (0.1 mumol l-1) or atenolol (0.3 mumol l-1) completely prevented the stimulatory effect of noradrenaline and isoprenaline on evoked transmitter output. 4. The facilitatory effect of isoprenaline declined, when the exposure time was increased. This observation supports the assumption that beta-adrenoceptors…

Effect of cocaine and related drugs on the uptake of noradrenaline by heart and spleen

1961

Noradrenaline uptake by heart and spleen after intravenous infusion of noradrenaline was measured in the pithed rat. Cocaine, given before the infusion, inhibited the noradrenaline uptake in relation (a) to the dose administered and (b) to the amount of noradrenaline infused. There was an association between increase in the pressor response to a test dose of noradrenaline and inhibition of the uptake by the heart. Drugs related chemically to cocaine, such as alpha-cocaine, amethocaine, and atropine, did not alter the noradrenaline uptake or potentiate the blood pressure response to noradrenaline. The noradrenaline uptake by the heart was unchanged after dibenamine, but blocked by the dichlo…

Supportive and Palliative care

2021

The definition of palliative and supportive care is often overwhelming and may be confused in common clinical practice. Supportive care is the multiprofessional attention to the individual’s overall physical, psychosocial, spiritual, and cultural needs and should be available at all stages of the illness. Palliative care shares the same objectives of supportive care, and some authors consider it in the advanced stages of disease. Actually it is important to carry out all these interventions from the earlier phases of disease to improve patient quality of life, to prevent therapy discontinuation for side effects, and hence to an optimization of outcomes. Quality of life is a heterogeneous co…

Conversion ratios for opioid switching in the treatment of cancer pain: a systematic review

2011

In this paper we describe the results of a systematic search of the literature on conversion ratios during opioid switching. This is part of a project of the European Palliative Care Research Collaboration to update the European Association for Palliative Care recommendations for the use of opioid analgesics in the treatment of cancer pain. Studies were eligible for inclusion if they involved adult patients with chronic cancer pain, contained data on opioid conversion ratios, were prospective and were written in English. Thirty-one studies were identified and included. The majority of the studies had methodological flaws and were not designed to explore or demonstrate equianalgesic dose da…

Percutaneous Stone Manipulation

1981

Percutaneous stone manipulation by direct ultrasound disintegration, extraction or chemolysis was done on 34 patients. A total of 15 patients presented with an operatively established nephrostomy, while percutaneous nephrostomy and subsequent dilation of the nephrostomy channel were done in 19. The rate of complete stone clearance was 19 of 20 stones after percutaneous nephrostomy and 8 of 16 stones in the group with an operatively established nephrostomy. The primary goal, to remove obstructing pelvic stones, was achieved in all cases. There were no untoward side effects, such as back pressure damage owing to flushing of the collecting system during ultrasound disintegration, or persistent…

Isoprenaline and forskolin increase evoked vasopressin release from rat pituitary

1982

Isolated neurointermediate lobes of rat pituitaries were incubated in Krebs solution. The vasopressin release evoked by electrical stimulation (0.2 ms, 80 V, 15 Hz, 10 s trains at 10 s intervals for a total of 10 min) was completely inhibited by tetrodotoxin. Isoprenaline increased the evoked vasopressin release to a maximum of 60% (EC50 10 nM) and this effect was antagonized surmountably by propranolol. Forskolin increased the vasopressin release by 98%. These results suggest the presence within the neurohypophysis of a beta-adrenoceptor-linked adenylate cyclase facilitating vasopressin secretion.

Other Methods to Assess Renal Damage

2015

Although glomerular filtration rate (GFR) and proteinuria remain gold standard in the evaluation of renal target organ damage, imaging techniques and image-derived parameters allow for both assessment of renal function and estimation of cardiovascular risk. Enhancement in digital image processing permits dynamic measurement of renal vascular and intraparenchymal processes in real time. The most relevant in terms of clinical use to assess hypertension-induced organ damage are the renal resistive index (RRI), renal calcium score, and functional magnetic resonance imaging.
