Social networking sites are a popular way for physicians to communicate about clinical, professional, and social topics. These sites can be used for educational purposes, professional interaction, and for general discussion. There are many popular sites oriented toward health care professionals, each with their own functionality and style. We reviewed the top physician-oriented networking sites, as well as popular general social networking sites that can be used for physician communication. We also provide background on social media communication, as well as specific advice for online physician communication and a discussion of confidentiality. © 2013, Lippincott Williams & Wilkins.

Methamphetamine (METH) causes partial depletion of central monoamine systems and cognitive dysfunction in rats and humans. We have previously shown and now further show that the positive correlation between expression of the immediate-early gene Arc (activity-regulated, cytoskeleton-associated) in the dorsomedial (DM) striatum and learning on a response reversal task is lost in rats with METH-induced striatal dopamine loss, despite normal behavioral performance and unaltered N-methyl-D-aspartate (NMDA) receptor-mediated excitatory post-synaptic currents, suggesting intact excitatory transmission. This discrepancy suggests that METH-pretreated rats may no longer be using the dorsal striatum to solve the reversal task. To test this hypothesis, male Sprague-Dawley rats were pretreated with a neurotoxic regimen of METH or saline. Guide cannulae were surgically implanted bilaterally into the DM striatum. Three weeks after METH treatment, rats were trained on a motor response version of a T-maze task, and then underwent reversal training. Before reversal training, the NMDA receptor antagonist DL-2-amino-5-phosphonopentanoic acid (AP5) or an Arc antisense oligonucleotide was infused into the DM striatum. Acute disruption of DM striatal function by infusion of AP5 impaired reversal learning in saline-, but not METH-, pretreated rats. Likewise, acute disruption of Arc, which is implicated in consolidation of long-term memory, disrupted retention of reversal learning 24 h later in saline-, but not METH-, pretreated rats. These results highlight the critical importance of Arc in the striatum in consolidation of basal ganglia-mediated learning and suggest that long-term toxicity induced by METH alters the cognitive strategies/neural circuits used to solve tasks normally mediated by dorsal striatal function. © 2012 American College of Neuropsychopharmacology.

Summary Objective To develop estimates of the direct cost of epilepsy in the United States for the general epilepsy population and sub-populations by systematically comparing similarities and differences in types of estimates and estimation methods from recently published studies. Methods Papers published since 1995 were identified by systematic literature search. Information on types of estimates, study designs, data sources, types of epilepsy, and estimation methods was extracted from each study. Annual per person cost estimates from methodologically similar studies were identified, converted to 2013 U.S. dollars, and compared. Results From 4,104 publications discovered in the literature search, 21 were selected for review. Three were added that were published after the search. Eighteen were identified that reported estimates of average annual direct costs for the general epilepsy population in the United States. For general epilepsy populations (comprising all clinically defined subgroups), total direct healthcare costs per person ranged from $10,192 to $47,862 and epilepsy-specific costs ranged from $1,022 to $19,749. Four recent studies using claims data from large general populations yielded relatively similar epilepsy-specific annual cost estimates ranging from $8,412 to $11,354. Although more difficult to compare, studies examining direct cost differences for epilepsy sub-populations indicated a consistent pattern of markedly higher costs for those with uncontrolled or refractory epilepsy, and for those with comorbidities. Significance This systematic review found that various approaches have been used to estimate the direct costs of epilepsy in the United States. However, recent studies using large claims databases and similar methods allow estimation of the direct cost burden of epilepsy for the general disease population, and show that it is greater for some patient subgroups. Additional research is needed to further understand the broader economic burden of epilepsy and how it varies across subpopulations. © Wiley Periodicals, Inc. © 2015 International League Against Epilepsy.

Allergic rhinitis (AR) and chronic idiopathic urticaria (CIU) are common causes of substantial illness and disability in preschool children. Antihistamines are commonly used to treat preschool children with these conditions, but their use is based mostly on extrapolated efficacy from adult populations; it is thus important to characterize the safety of antihistamines in the pediatric population. This study was designed to assess the safety of levocetirizine dihydrochloride oral liquid drops in infants and children with AR or CIU. Two multicenter, double-blind, randomized, parallel-group studies randomized infants aged 6-11 months (study 1, n = 69) and children aged 1-5 years (study 2, n = 173) to levocetirizine, 1.25 mg (q.d. or b.i.d., respectively), or placebo for 2 weeks, using a 2:1 ratio. Safety evaluations included treatment-emergent adverse events (TEAEs), vital signs, electrocardiographic (ECG) assessments, and laboratory tests. The overall incidence of TEAEs was similar between levocetirizine and placebo in both studies. Most TEAEs were mild or moderate in intensity. TEAEs prompted discontinuation of therapy in three patients receiving levocetirizine in study 1. No clinically relevant changes from baseline in vital signs or laboratory parameters were apparent in either study; changes from baseline in these evaluations were similar between groups. No significant changes were observed in ECG parameters, including corrected QT interval. Levocetirizine, 1.25 and 2.5 mg/day, was well tolerated in infants aged 6-11 months and in children aged 1-5 years, respectively, with AR or CIU. Copyright © 2010, OceanSide Publications, Inc.

A randomized, double-blind, placebo-controlled study (N01103, NCT00105040) evaluated behavioral and emotional effects of adjunctive levetiracetam (LEV) treatment in children and adolescents (4-16. years old) with uncontrolled partial-onset seizures. Patients received adjunctive LEV 20-60. mg/kg/day (n=64) or placebo (n=34) for 12. weeks. The Achenbach Child Behavior Checklist (CBCL) and portions of the Child Health Questionnaire-Parent Form 50 (CHQ-PF50) were used to assess behavioral and emotional functioning at baseline and end of the treatment period. Worsening of the mean CBCL Aggressive Behavior score occurred for LEV but not placebo, leading to similar results for Externalizing Syndromes and Total Problems (all P<0.05 vs placebo). The change in the CBCL Activities Competence score favored LEV (P<0.05). These results are in line with the known safety profile of LEV. © 2010 Elsevier Inc.
