Artificial intelligence for reduced dose 18F-FDG PET examinations: a real-world deployment through a standardized framework and business case assessment.

Background: To determine whether artificial intelligence (AI) processed PET/CT images of reduced by one-third of 18-F-FDG activity compared to the standard injected dose, were non-inferior to native scans and if so to assess the potential impact of commercialization.

Materials And Methods: SubtlePET™ AI was introduced in a PET/CT center in Italy. Eligible patients referred for 18F-FDG PET/CT were prospectively enrolled.

Autosomal recessive progressive myoclonus epilepsy due to impaired ceramide synthesis.

Autosomal recessive progressive myoclonus epilepsy due to impaired ceramide synthesis is an extremely rare condition, so far reported in a single family of Algerian origin presenting an unusual, severe form of progressive myoclonus epilepsy characterized by myoclonus, generalized tonic-clonic seizures and moderate to severe cognitive impairment, with probable autosomal recessive inheritance. Disease onset was between 6 and 16 years of age. Genetic study allowed to identify a homozygous nonsynonymous mutation in CERS1, the gene encoding ceramide synthase 1, a transmembrane protein of the endoplasmic reticulum (ER), catalyzes the biosynthesis of C18-ceramides.

Head-to-Head Comparison of Aripiprazole and Risperidone in the Treatment of ADHD Symptoms in Children with Autistic Spectrum Disorder and ADHD: A Pilot, Open-Label, Randomized Controlled Study.

Background: Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are frequently overlapping neurodevelopmental disorders. Individuals in whom the disorders are comorbid show more severe impairment because of deficits in the processing of social situations, adaptive functioning, and executive control than individuals with either disorder alone.

Objective: This open-label pilot study aimed to evaluate and compare the efficacy and tolerability of risperidone and aripiprazole for treating ADHD symptoms in patients with both ASD and ADHD over the course of 24 weeks of treatment.

Genetics of reflex seizures and epilepsies in humans and animals.

Introduction: Reflex seizures are epileptic events triggered by specific motor, sensory or cognitive stimulation. This comprehensive narrative review focuses on the role of genetic determinants in humans and animal models of reflex seizures and epilepsies.

Methods: References were mainly identified through MEDLINE searches until August 2015 and backtracking of references in pertinent studies.

Rapid versus slow withdrawal of antiepileptic monotherapy in 2-year seizure-free adult patients with epilepsy (RASLOW) study: a pragmatic multicentre, prospective, randomized, controlled study.

Antiepileptic drug withdrawal may be an option for patients who have been seizure free for some years. The best withdrawal rate is questionable; in particular, it is unknown whether "rapid" withdrawal is associated with a higher risk of relapse as compared to "slow" withdrawal. We aim to establish if a slow or a rapid withdrawal schedule of antiepileptic monotherapy influences relapse rate in adult patients with focal or generalized epilepsy who have been seizure free for at least 2 years.

Evaluation of acute cardiovascular effects of immediate-release methylphenidate in children and adolescents with attention-deficit hyperactivity disorder.

Attention-deficit hyperactivity disorder is a frequent condition in children and often extends into adulthood. Use of immediate-release methylphenidate (MPH) has raised concerns about potential cardiovascular adverse effects within a few hours after administration. This study was carried out to investigate acute effects of MPH on electrocardiogram (ECG) in a pediatric population.

Generic Olanzapine Substitution in Patients With Schizophrenia: Assessment of Serum Concentrations and Therapeutic Response After Switching.

Background: Several reports of loss of efficacy or adverse effects have been described after generic substitution of antipsychotics. To date, studies comparing serum drug levels in patients switched to generic antipsychotics in a standard clinical setting are lacking. The aim of this study was to investigate if switching to generic olanzapine in patients affected by schizophrenia is associated with differences in its serum concentrations and therapeutic response.

Indications of newer and older anti-epileptic drug use: findings from a southern Italian general practice setting from 2005-2011.

Aims: The aim of the study was to analyze the prescribing pattern of both newer and older AEDs.

Methods: A population of almost 150 000 individuals registered with 123 general practitioners was included in this study. Patients who received at least one AED prescription over 2005-2011 were identified.

Minor and repetitive head injury.

Traumatic brain injury (TBI) is the leading cause of death and disability in the young, active population and expected to be the third leading cause of death in the whole world until 2020. The disease is frequently referred to as the silent epidemic, and many authors highlight the "unmet medical need" associated with TBI.The term traumatically evoked brain injury covers a heterogeneous group ranging from mild/minor/minimal to severe/non-salvageable damages.

Effectiveness of risk minimization measures for cabergoline-induced cardiac valve fibrosis in clinical practice in Italy.

On June 2008, the European Medicines Agency (EMA) introduced changes to the Summary of Product Characteristics (SPC) for cabergoline and pergolide, to reduce the risk of cardiac valvulopathy in users of these drugs. To assess the effectiveness of EMA recommendations in Italian clinical practice, we retrospectively reviewed medical charts of patients with degenerative Parkinsonism treated with cabergoline in three large Italian clinics between January 2006 and June 2012. The prevalence and the severity of cardiac valve regurgitation were assessed in patients who stopped cabergoline therapy prior to June 2008 or continued therapy after that date.

Pharmacokinetic and pharmacodynamic interactions between antiepileptics and antidepressants.

Introduction: Antiepileptic-antidepressant combinations are frequently used by clinicians; their pharmacokinetic (PK) and pharmacodynamic (PD) drug interactions (DIs) have not been well studied but are frequently likely to be clinically relevant.

Areas Covered: This article provides a comprehensive review of PK DIs between antiepileptics and antidepressants. In the absence of PD DI studies, PD information on pharmacological mechanisms and studies on efficacy and safety of individual drugs are reviewed.

Complications of trauma patients admitted to the ICU in level I academic trauma centers in the United States.

Background: The aims of this study were to evaluate the complications that occur after trauma and the characteristics of individuals who develop complications, to identify potential risk factors that increase their incidence, and finally to investigate the relationship between complications and mortality.

Methods: We did a population-based retrospective study of trauma patients admitted to ICUs of a level I trauma center. Logistic regression analyses were performed to determine independent predictors for complications.

Changes in the prescribing pattern of antidepressant drugs in elderly patients: an Italian, nationwide, population-based study.

Background: Despite the high use of antidepressants (ADs) among the elderly, there is limited information about the prescribing pattern of these drugs in the Italian elderly population. The aim of this study was to analyze the trend in the use of ADs in the Italian elderly patients in the years 2003-2009, and specifically, to evaluate rates and predictors of AD treatment discontinuation in depressed older patients.

Methods: The nationwide general practice Health Search Database (HSD) was used to identify AD users aged 65 years old and over from 2003 to 2009.

ECG parameters in children and adolescents treated with aripiprazole and risperidone.

Atypical antipsychotics (AP) are increasingly being used in children and adolescents for the treatment of psychiatric disorders. Atypical AP may cause QT prolongation on the electrocardiogram (ECG), which predisposes patients to an increased risk of developing threatening ventricular arrhythmias. Although this phenomenon has been exhaustively reported in adults, few studies investigated the safety of these drugs in pediatric patients.

Effects of L'Aquila earthquake on the prescribing pattern of antidepressant and antipsychotic drugs.

Background: Natural disasters provoke an increase in mental and medical disorders in survivors. Monitoring drug prescription changes after natural disasters can provide an indirect evaluation of trauma impact in the population. Moreover, it could be useful to both identify risk categories that require special assistance and assess possible drug abuse or misuse.

Ketotifen-induced nocturnal bruxism.

Unlabelled: Nocturnal bruxism is a common oromandibular movement disorder highly prevalent in children, but its pathophysiological mechanism has not been fully explained. Iatrogenic sleep bruxism has been described following treatment with several psychotropic medications. However, no case of antihistamine-induced bruxism has been reported to date.

The challenge of mild traumatic brain injury: role of biochemical markers in diagnosis of brain damage.

During the past decade there has been an increasing recognition of the incidence of mild traumatic brain injury (mTBI) and a better understanding of the subtle neurological and cognitive deficits that may result from it. A substantial, albeit suboptimal, effort has been made to define diagnostic criteria for mTBI and improve diagnostic accuracy. Thus, biomarkers that can accurately and objectively detect brain injury after mTBI and, ideally, aid in clinical management are needed.

Clinical pharmacokinetics of new-generation antiepileptic drugs at the extremes of age: an update.

Epilepsies occur across the entire age range, and their incidence peaks in the first years of life and in the elderly. Therefore, antiepileptic drugs (AEDs) are commonly used at the extremes of age. Rational prescribing in these age groups requires not only an understanding of the drugs' pharmacodynamic properties, but also careful consideration of potential age-related changes in their pharmacokinetic profile.

α-Synuclein in CSF of patients with severe traumatic brain injury.

Objective: The study aims to examine α-synuclein in the CSF of patients with severe traumatic brain injury (TBI) and its relationship with clinical characteristics and long-term outcomes.

Methods: This prospective case-control study enrolled patients with severe TBI (Glasgow Coma Score ≤ 8) who underwent ventriculostomy. CSF samples were taken from each TBI patient at admission and daily for up to 8 days after injury and successively assessed by ELISA.

Acute cerebellar ataxia following meningococcal group C conjugate vaccination.

Acute cerebellar ataxia is the most common cause of childhood ataxia, usually resulting from infections or vaccinations. Cases of acute cerebellar ataxia have been reported as a consequence of several viral and bacterial infections as well as immunizing agents, such as varicella, influenza, hepatitis B, and diphtheria-pertussis-tetanus vaccines. Although immunization with meningococcal group C conjugate vaccines has been associated with several neurological side effects, acute cerebellar ataxia has not been previously reported.
