Evaluation of the Burden of HPV-Related Hospitalizations as a Useful Tool to Increase Awareness: 2007–2017 Data from the Sicilian Hospital Discharge …
2020
In light of the implementation of human papillomavirus (HPV) prevention strategies, epidemiological studies in different geographical areas are required in order to assess the impact of HPV-related diseases. The purpose of the present study was to describe the burden of HPV-related hospitalizations in Sicily. A retrospective observational study estimated 43,531 hospitalizations attributable to HPV from 2007 to 2017. During the observed period, there was a decrease for all HPV-related conditions with a higher reduction, among neoplasms, for cervical cancer (annual percent change (APC) = &minus
Resistin: An Inflammatory Cytokine. Role in Cardiovascular Diseases, Diabetes and the Metabolic Syndrome
2014
Resistin is an adipocyte- and monocyte-derived cytokine which has been implicated in the modulation of insulin action, energy, glucose and lipid homeostasis. Resistin has been associated with insulin resistance and many of its known complications. As a molecular link between metabolic signals, inflammation, and vascular dysfunction, resistin can be proposed as playing a significant role in the heightened inflammatory state induced by metabolic stress linked to excessive caloric intake, thus contributing to the risk for metabolic syndrome (MetS), type 2 diabetes (T2DM), and cardiovascular diseases (CVD). In this review, we highlighted the role of resistin, as an inflammatory cytokine, in the…
Pharmacological treatments for opiate and alcohol addiction: A historical perspective of the last 50 years.
2018
Addiction pharmacotherapy aims to prevent drug abstinence symptoms, reduce drug craving and relapse, and normalize physiologic functions disrupted by chronic use of the drug. During the last 50 years, there has been an enormous revolution in pharmacotherapy for drug addiction. From abstinence as practically the only treatment option available, there are now multiple drugs on the market that have proved their efficacy in treating opiate and alcohol disorders. The present review will focus on the pharmacological treatments of the drugs whose consumption most affects individuals and society: alcohol and opiates. We will review the drugs most widely prescribed to prevent relapse and maintain ab…

Role of neurophysiology in the clinical practice of primary pediatric headaches
2007
The role of electrophysiological studies in pediatric headaches is controversial. In childhood headaches, neurophysiological examinations are of interest for potential clinical use because they are noninvasive and are scarcely influenced by environmental factors or drug use. Electrophysiological studies in childhood headache principally explored the role of electroencephalographic (EEG) evaluations in migraine, while less evidence has been reported about other neurophysiological techniques, such as evoked potentials, event-related potentials, and, less often, transcranial magnetic stimulation. In this brief review, we point out our attention to the aid of neurophysiological methods in the c…
Preclinical progress with CHF2819, a novel orally active acetylcholinesterase inhibitor
2002
(-)-(3aS,8aS,1S)-1,2,3,3a,8,8a-hexahydro-1,3a,8-trimethylpyrrolo[2,3-b]indol-5-ol-2′-ethylphenylcarbamate N-oxide hydrochloride (CHF2819) is a novel, orally active acetylcholinesterase inhibitor (AChEI) for Alzheimer's disease (AD). CHF2819 appears as a selective inhibitor of AChE, being 115 times more potent against this enzyme than butyrylcholinesterase (BuChE). Moreover, CHF2819 appears more selective for inhibiting central (brain) than peripheral (heart) AChE. In vivo studies show that CHF2819 significantly increases acetylcholine (ACh) levels in young adult rat hippocampus in a dose-dependent manner. Moreover, aged animals exhibit a marked increase in hippocampal concentrations of this…
Protrhombotic Effects of Contraceptives
2010
The use of oral contraceptives first became widespread some 40 years ago, and reports of an excess risk of cardiovascular disease among women who used these agents soon followed. Few drugs have been the object of such intensive epidemiological research, the outcome of which has provided clinicians with detailed information about risks not only of specific thrombotic diseases but also important non-contraceptive benefits from the pill. Recently, oral contraceptives have been classified by some according to "generation" (first, second, third, and most recently, fourth generation): first-generation formulations containing lynestrenol or norethindrone, second-generation formulations containing …
The role of fibrate treatment in dyslipidemia: an overview.
2012
Dyslipidemia, and especially atherogenic dyslipidemia, a combination of small low-density lipoproteins cholesterol (LDL-C), decreased high-density lipoprotein cholesterol (HDL-C) and increased triglyceride (TG) concentrations, represents a major cardiovascular (CV) risk factor. Nuclear receptor peroxisome proliferator-activated receptors (PPARs) are involved in the regulation of lipid metabolism; PPAR ligands are used to treat dyslipidemias. Fibrates have a major impact on TG metabolism as well as on modulating LDL size and subclasses. Fibrates target atherogenic dyslipidemia by increasing plasma HDL-C concentrations and decreasing small dense LDL (sdLDL) particles and TGs, thus contributin…
Pharmacokinetic Study on Adenomatous Prostate Tissue Concentrations of Cef operazone

Cephalosporins do not reach active therapeutical concentrations in the prostatic tissue in patients suffering from chronic bacterial prostatitis. Cefoperazone is an exception. Its efficacy in the trea
Methotrexate-Loaded Polymethylmethacrylate Bone Cement for Local Bone Metastasis Therapy: Pilot Animal Study in the Rabbit Patellar Groove
2008
Local chemotherapy is an option in bone metastasis treatment. On the other hand, evaluation of side effects on bone is a difficult issue in drug development and biomaterials research. Most animal models to date are inappropriate or not feasible. Rabbits are an alternative to other bigger mammals and have an appropriate bone structure compared to rats and mice. The patellar groove model of the rabbit offers a standardized and sensitive model to evaluate bone-compromising drug effects. We tested the system with a reproducible polymethacrylate implant as carrier and loaded this system with methotrexate. Three methotrexate concentrations were used in the test samples (250 mg, 1 g and 4 g per 40…
