Cost effectiveness of boceprevir or telaprevir for previously treated patients with genotype 1 chronic hepatitis C.
2013
Background & Aims Randomised controlled trials (RCTs) show that triple therapy (TT) with peginterferon alfa, ribavirin, and boceprevir (BOC) or telaprevir (TVR) is more effective than peginterferon-ribavirin dual therapy (DT) in the treatment of genotype 1 (G1) chronic hepatitis C (CHC) patients with previous relapse (RR), partial response (PAR), and null-response (NR). We assess the cost-effectiveness of TT compared to no therapy in the treatment of patients previously treated with G1 CHC. Methods The available published literature provided the data source. The target population was made up of previously treated Caucasian patients with G1 CHC and these were evaluated over a lifetime horizo…
Non-convulsive status epilepticus associated with tiagabine in a pediatric patient
2003
We report a 4-year-old patient who developed non-convulsive status epilepticus (NCSE) following tiagabine (TGB) as add-on treatment for refractory partial seizures. NCSE occurred while the patient received TGB 0.83mg/kg/day. In our case, the TGB reduction led to a significant improvement of electroclinical features. The mechanisms of this abnormal effect are not clear. GABA-ergic hyperfunction and/or multiplicity of interlinked brain GABA systems associated with individual specific sensitivity could play a critical role in the pathogenesis of NCSE. This is the first report of NCSE documented by electroencephalogram (EEG) in a child under 12 years of age on TGB treatment. © 2003 Elsevier Sci…
Role of Associated Cortical Lesions in Motor Partial Seizures and Lenticulostriate Infarcts
1995
In a population-based study, we evaluated seizures occurring in the first 15 days after strokes among 1,640 consecutive patients who had ischemic (814 infarcts with atheroma and 126 with cardiogenic embolism, 273 lacunar infarcts, 259 transient ischemic attacks) or hemorrhagic stroke (129 supratentorial hematomas and 24 subarachnoïd hemorrhage) on computed tomography (CT) scan. Ninety patients had an epileptic seizure in the first 15 days after stroke onset. Thirteen of the 90 had a lenticulostriate infarct, diagnosed on CT scan, without an apparent ipsilateral cortical ischemic lesion. No lenticulostriate hematoma was observed with seizures. To determine the possible existence of an ipsila…
A randomized, double-blind comparison of antiepileptic drug treatment in the elderly with new-onset focal epilepsy.
2015
Objective: To compare the effectiveness of controlled-released carbamazepine (CR-CBZ) to levetiracetam (LEV) and to lamotrigine (LTG) in elderly patients with newlydiagnosedfocalepilepsy.Methods: Randomized, double-blind, parallel-group trial conducted between January2007andAugust2011,in47ambulatoryorhospitalsitesinGermany,Austria,orSwit-zerland. Eligible participants were aged ≥60, had new-onset epilepsy, had no acute ill-nessasthecauseoftheirseizures,andhadnocontraindicationtothedrugsinthetrial.Patients were randomized 1:1:1 to CR-CBZ, LTG, or LEV. Doses were up-titrated for6 weeks and could be maintained or adjusted depending on seizure relapse or tolera-bility over an additional period …
External validation of the preoperative Karakiewicz nomogram in a large multicentre series of patients with renal cell carcinoma
2012
Purpose: To perform a formal external validation of the preoperative Karakiewicz nomogram (KN) for the prediction of cancer-specific survival (CSS) using a large series of surgically treated patients diagnosed with organ-confined or metastatic renal cell carcinoma (RCC). Methods: Patient population originated from a series of retrospectively gathered cases that underwent radical or partial nephrectomy between years 1995 and 2007 for suspicion of kidney cancer. The original Cox coefficients were used to generate the predicted risk of CSS at 1, 2, 5, and 10 years following surgery and compared to the observed risk of CSS in the current population. External validation was quantified using meas…
Effects of prosthetic treatment for shortened dental arches on oral health-related quality of life, self-reports of pain and jaw disability: results …
2005
A multi-centre randomized clinical trial is under way at 14 university dental schools in Germany to compare prosthodontic treatments for the shortened dental arch (SDA). One of the aims of this pilot-study was to measure the effect of two treatment options of the SDA on oral health-related quality of life and on the Research Diagnostic Criteria (RDC) for temporomandibular disorders (TMD). Thirty-four patients participated in the pilot-study. Inclusion criteria were: all molars were missing and the presence of at least both canines and one premolar in each quadrant. Participants were randomly assigned to receive either removable partial dentures including molar replacement (RPD_group) or ret…
Cholecystokinin-8 sulfate modulates the anticonvulsant efficacy of vigabatrin in an experimental model of partial complex epilepsy in the rat.
2009
Summary Purpose: We evaluated the possible additive effect induced by the administration of the anticonvulsant vigabatrin (VGB) and cholecystokinin-8 sulfate (CCK-8S) on an experimental model of partial complex seizures (maximal dentate gyrus activation, MDA). Moreover, the functional involvement of γ-aminobutyric acid (GABA) neurotransmission was tested by iontophoretically administering bicuculline (GABA receptor antagonist) in the dentate gyrus. Methods: Urethane anesthetized rats were pretreated with VGB (50, 100 or 200 mg/kg, i.p.) or CCK-8S (8 nmol/kg, i.p.) alone or coadministered with VGB (50 mg/kg, i.p.). Dentate gyrus epileptic activity was obtained through the repetitive electr…
Elective partial nephrectomy is equivalent to radical nephrectomy in patients with clinical T1 renal cell carcinoma: results of a retrospective, comp…
2012
Study Type - Therapy (cohort) Level of Evidence 2b What's known on the subject? and What does the study add? Few studies supported the expanded indications for nephron-sparing surgery (NSS) in selected patients with 4.1 cm renal tumours in the size range (T1b). However, all these comparative studies included both imperative and elective partial nephrectomy and patient selection for analysis was based on pathological stage (pT1) and not on clinical stage (cT1). Patients with clinically organ-confined RCC (cT1) who are candidates for elective PN have a limited risk of clinical understaging. NSS is not associated with an increased risk of recurrence and cancer-specific mortality both in cT1a a…
Modelling of Pe C alloys solidification using the artificial heat source method
1997
Abstract In the paper the numerical solutions concerning the cast iron and also the carbon steel solidification are presented. In order to take into account the non-linearities appearing in differential equations describing the boundary-initial problem considered — a certain algorithm called the artificial heat source method has been used. The examples illustrating the possibilities of proposed method applications have been solved by means of the boundary element method, but the others numerical methods can be also utilized.
Characterization of Non-linear Inductors Including Thermal Effects for Power Applications
2018
This paper is focused on the behaviour of non-linear inductors employed in DC/DC switching converters considering the effects due to variations of both current and temperature. The characterization of the inductors is performed by a buck converter operated to stimulate the inductor under test by a constant current with superimposed a large signal. The measurements are carried out at several inductor’s temperature values. Data are automatically collected by a novel virtual instrument developed by the authors in LabVIEW® environment aiming to obtain a polynomial based analytical model. The deep knowledge of the inductor model allows its design to be optimized improving the power density of th…
