Fluorescein for resection of high-grade gliomas: A safety study control in a single center and review of the literature
2017
Background: The importance of a complete resection of high-grade gliomas (HGGs) has been highlighted in scientific literature, in order to limit tumor recurrence and above all to improve disease-free survival rates. Several fluorescent biomarkers have been tested to improve intraoperative identification of residual tumor; 5-aminolevulinic acid (5-ALA) and fluorescein sodium (FS) are now starting to play a central role in glioma surgery. We performed a retrospective analysis on 47 patients operated for HGGs. Here we report our preliminary data. Methods: Data of 47 consecutive patients with HGG have been collected in our study (25 males, 22 females; mean age: 60.3 years, range: 27-86 years). …
Survey of root canal irrigating solutions used in dental practices within Germany.
2014
Aim Irrigant usage information in relation to years of professional experience was collected from general dentists in different German federal states by means of a questionnaire. Methodology A short survey concerning endodontic treatment and use of irrigants was mailed to 4240 dentists or delivered to 3720 dental offices as an extra page in a journal in eight German states. Detailed information concerning the most frequently used irrigants, their concentrations, the spectrum of disinfectants used in root canal treatment concepts for vital and nonvital pulps, main topics of continuing education as well as years of professional experience was collected. The statistical analysis of differences…
Sodium Oxybate Therapy for Alcohol Withdrawal Syndrome and Keeping of Alcohol Abstinence
2018
BACKGROUND Gamma-hydroxybutyrate (GHB or sodium oxybate) is both an exogenous and endogenous molecule with neuromodulator properties. In the United States, GHB is an approved drug for the treatment of narcolepsy and narcolepsy with cataplexy in adults. In some European Union countries, sodium oxybate is applied for the treatment of opioid and alcohol withdrawal. OBJECTIVE The aim of the present review was to describe the state of art of the pre-clinical research and the clinical evidence related to GHB used alone or in combination with other treatments in alcohol withdrawal syndrome and alcohol abstinence maintenance. METHOD Internationally published pre-clinical findings and clinical studi…
PO-0322 The Effective Dose Of Sodium Bicarbonate In Severe Acute Dehydration And Metabolic Acidosis Due To Acute Diarrhoea In Children
2014
Background Still exist controversies about sodium bicarbonate (SB) effectiveness in metabolic acidosis (MA). The SB dose finally remain at discretion of physician. Aims Proving SB efficiency in severe acute dehydration (SAD) with MA secondary to acute diarrhoea (AD) in children. Methods Retrospective study conducted between May–September 2013, in 0–5 years old patients hospitalised for AD with SAD and MA. We chose the propitious age group and season for acute gastrointestinal pathology. We considered SAD loss >10% of body weight and severe MA pH Results In A Group, at admission, 57,14% presented pH 15; at 4 H, all presented alkalosis. In B Group, at admission, 50% presented severe MA; at 1 …
Secretory effect of azodisalicylate (azodisal sodium) on the short circuited mucosa of the rat ileum in vitro.
1988
Azodisalicylate (ADS) is one of the newly developed substitutes of sulphasalazine consisting of two molecules of 5-amino-salicylic acid. Azodisalicylate caused diarrhoea in some patients, apparently caused by an antiabsorptive secretagogue action of this compound. The mechanism of this was studied in the short circuited isolated mucosa of the rat ileum. Mucosal addition of ADS increased the potential difference (PD) and short circuit current (Isc) at a concentration of 1.3.10(-4) mol/l (4 mg/dl) with maximal effects at 1.3.10(-3) mol/l (40 mg/dl). Epithelial resistance was only slightly decreased at the higher concentrations of 40 and 100 mg/dl. Serosal ADS had no effect on electrical param…
Sodium-hydrogen exchange inhibition: novel strategy to prevent myocardial injury following ischemia and reperfusion.
1999
Activation of Na+/H+ exchange and subsequent calcium overload in cardiac myocytes appear to play an important role in myocardial tissue injury following ischemia and reperfusion. Results of several in vitro studies in isolated myocytes and heart preparations and in vivo studies in pigs and rats have suggested that inhibition of Na+/H+ exchange is an effective means to prevent lethal reperfusion injury, arrhythmia, and improve myocardial contractile dysfunction. In patients with acute myocardial infarction (MI), any preventive agent is administered immediately before or shortly after reperfusion, rather than before the occurrence of coronary occlusion. The direct interventional approach to t…
Model-specific effects of bumetanide on epileptiform activity in the in-vitro intact hippocampus of the newborn mouse.
2007
The immature brain has a higher susceptibility to develop seizures, which often respond poorly to classical pharmacological treatment. It has been recently suggested that bumetanide, which blocks Na(+)-dependent K(+)-Cl(-)-cotransporter isoform 1 (NKCC1) and thus attenuates depolarizing GABAergic responses, could soothe epileptiform activity in immature nervous systems. To evaluate whether bumetanide consistently attenuates epileptiform activity, we investigated the effect of 10 microM bumetanide in five different in-vitro epilepsy models using field potential recordings in the CA3 region of intact mouse hippocampal preparations at postnatal day 4-7. Bumetanide reduced amplitude and frequen…
Analysis of radiolucent gallstones by computed tomography for in vivo estimation of stone components.
1990
. Successful oral litholytic and other non-operative therapies of gallstones require exact determination of the stone components. Since computed tomography (CT) provides highly sensitive measurement of density, we performed a study to evaluate whether CT measurement of stone density allows a prediction of the composition of radiolucent gallstones. Twenty-eight patients presenting with 29 radiolucent gallbladder (n= 17) or common bile duct stones (n=12) were included. Prior to operative or endo-scopic therapy the attenuation values (Hounsfield Units, HU) were assessed in vivo by CT under standardized conditions (Somatom II, 125 KV, 130 mAs). After surgical or endoscopic stone removal the con…
Narratives of Patients with Fatal Outcomes During the Phase 2 TITAN and Phase 3 HERCULES Studies
2019
Background: Acquired thrombotic thrombocytopenic purpura (aTTP) is a rare but life-threatening thrombotic microangiopathy, with an untreated mortality rate of >90%. Prompt treatment with therapeutic plasma exchange (TPE) and immunosuppression improves outcomes in patients with aTTP, but 10-20% of patients still die acutely from this disease. The aim of this analysis was to describe in more detail the characteristics and disease courses of the patients who died during the caplacizumab clinical development program. Methods: Patient narratives on all deaths occurring during the phase 2 TITAN and phase 3 HERCULES studies were extracted. Results: In the overall study periods, a total of 6 pat…
Inspired supplemental oxygen reduces markers of oxidative stress during elective colon surgery.
2007
.Anaesthesia was induced with sodium thiopental andfentanyl, and maintained with sevoflurane. After inductionof anaesthesia, patients were randomly assigned 30 or80 per cent oxygen throughout surgery and for 6 hafterwards. During surgery, lungs were ventilated involume-controlled mode (10 ml/kg), whereas during the6 h afterwards respiration was spontaneous with an oxygenmask (16 l/min)
