Chelation treatment in sickle-cell-anaemia: much ado about nothing?

2011

Summary Blood transfusions may prevent and treat serious complications related to sickle-cell disease (SCD) when performed according to specific guidelines. However, blood transfusion requirements in SCD inevitably lead to increased body iron burden. An adequate chelation treatment may prevent complications and reduce morbidity and mortality. This review evaluates the effectiveness, safety and costs of chelation treatment. The included trials were examined according to the recommendations of the American College of Cardiology (ACC) and the American Heart Association (AHA). Overall, 14 trials and a total of 502 patients with SCD were included in this review. Deferoxamine alone (s.c. or i.v.)…

The dilemma for patients with chronic hepatitis C: treat now or warehouse?

2013

Dual therapy with peginterferon and ribavirin, the only treatent for chronic hepatitis C available In Italy and in many other ountries worldwide up to 2013, obtains satisfactory response ates in infections with hepatitis C virus (HCV) genotype 2, but far rom optimal for other genotypes [1,2]. Eradication requires 6–12 onths of therapy, with significant inconvenience for patients: dverse reactions force premature termination in about 20% of atients and reduced the quality of life for almost all who persist n treatment. In view of the important and prolonged side effects, nterferon-based treatment is perceived as a nightmare by many symptomatic,well-being, socially activepatients (the largema…

Cost-effectiveness of bedaquiline in MDR and XDR tuberculosis in Italy

2016

ABSTRACT Objective: To evaluate the cost-effectiveness of bedaquiline plus background drug regimens (BR) for multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) in Italy. Methods: A Markov model was adapted to the Italian setting to estimate the incremental cost-effectiveness ratio (ICER) of bedaquiline plus BR (BBR) versus BR in the treatment of MDR-TB and XDR-TB over 10 years, from both the National Health Service (NHS) and societal perspective. Cost-effectiveness was evaluated in terms of life-years gained (LYG). Clinical data were sourced from trials; resource consumption for compared treatments was modelled according to advice from an expert c…

The new frontier of bone formation: a breakthrough in postmenopausal osteoporosis?

2009

Osteoporosis is a chronic disease that accelerates after menopause in many women. Most of the pharmacologic attempts to control the disease, such as hormone therapy, have emphasized the constraint of bone resorption. Since recent years have witnessed important advances in the field of bone formation, this review aims to update the present knowledge on the mechanisms affecting osteoblastogenesis and on the therapeutic results achieved by recently approved drugs.We sought peer-reviewed, full-length basic and clinical articles published between 1995 and May 2008 using a PubMed search strategy, with the terms osteoporosis and osteoblast, osteoporosis and strontium ranelate, and osteoporosis and…

Muscarinic mobilization of choline in rat brain in vivo as shown by the cerebral arterio-venous difference of choline.

1987

In anesthetized rats, the choline levels of cerebrospinal fluid and plasma obtained from blood collected from peripheral vessels (carotid artery, cardiac vessels) and from the transverse sinus were determined with a radioenzymatic assay. Cortical release of choline was studied using the "cup technique." The plasma choline level of the peripheral blood (11.5 mumol/L) was lower than that of the sinus blood. The resulting cerebral arterio-venous difference of choline was negative (3.2 mumol/L) and reflected the net release of choline from the whole brain. The plasma choline levels were not different irrespective of whether the rats were anesthetized with ether, urethane, or pentobarbital. Howe…

Long-term outcome of antiandrogen monotherapy in advanced prostate carcinoma: 12-year results of a phase II study

2003

OBJECTIVE To present the long-term outcome of patients with locally advanced or metastatic prostate carcinoma treated by first-line antiandrogen monotherapy. PATIENTS AND METHODS From 1983 to 1990, 41 patients with advanced prostate carcinoma were treated with flutamide monotherapy until progression or the appearance of toxicity. Twenty-five patients (61%) had T3-T4N0M0 and 16 (39%) T2–4N0–3M1 prostate carcinoma. Consensus criteria were adopted to evaluate the response. Plasma testosterone and sexual function were recorded for the first 3 years. RESULTS Flutamide was administered for up to 147 months; seven patients (17%) interrupted the treatment because of toxicity. There was an objective…

Infradian rhythms of serotonin and serotonin‐N‐acetyltransferase in the pineal gland of male rats

1983

Abstract The present investigation was carried out to determine whether in the pineal gland of male Sprague‐Dawley rats infradian rhythms with respect to serotonin, serotonin‐N‐acetyltransferase (NAT) activity, and hydroxyindole‐O‐methyltransferase (HIOMT) can be detected. The serotonin data obtained over a period of 4 weeks and subjected to power spectral analysis suggest the presence of infradian rhythms in the range of 6 and 4.3 days. NAT activity, obtained over a period of 28 days, revealed a 7‐day‐rhythm. A second peak occurring at 2.3 days remained just below the significance limit. HIOMT activity studied over a period of 8 days showed no statistically significant differences between …

Periodontal condition and recurrence of periodontitis associated with alcohol consumption in periodontal maintenance therapy

2020

Background This study followed individuals in periodontal maintenance therapy (PMT) over 6 years and longitudinally evaluated the effects of the frequency of alcohol consumption on the recurrence of periodontitis (RP). Material and methods From a 6-year follow-up cohort study with 268 individuals under PMT, 142 patients who attended at least one PMT visit within 12 months were determined to be eligible. Based on their alcohol consumption, participants were categorized into 3 groups: none or occasional alcohol use (NA; n=88), moderate alcohol use (MA; n=26) and intense alcohol use (IA; n=24). Complete periodontal examination and alcohol consumption were evaluated at 2 times, T1 (after active…

Biological interactions between calcium silicate-based endodontic biomaterials and periodontal ligament stem cells: A systematic review of in vitro s…

2021

Background Most recently, the biological interactions, that is cytocompatibility, cell differentiation and mineralization potential, between calcium silicate-based biomaterials and periodontal ligament stem cells (PDLSCs) have been studied at an in vitro level, in order to predict their clinical behaviour during endodontic procedures involving direct contact with periodontal tissues, namely root canal treatment, endodontic surgery and regenerative endodontic treatment. Objective The aim of the present systematic review was to present a qualitative synthesis of available in vitro studies assessing the biological interaction of PDLSCs and calcium silicate-based biomaterials. Methodology The p…
