Objectives Randomized controlled trials (RCTs) have established the efficacy of galcanezumab, an antibody binding calcitonin gene-related peptide (CGRP) ligand, in the preventive treatment of migraine. The objective was to summarize real-world data evaluating galcanezumab in the preventive treatment of migraine, to complement RCT results with evidence observed in clinical practice. Methods A literature search was conducted to identify real-world studies evaluating galcanezumab in the treatment for patients with migraine. Results Twenty-five studies were identified; some only evaluated galcanezumab, and others used pooled data from multiple anti-CGRP antibodies. The studies recruited diverse patient populations, including patients who had failed multiple prior preventive therapies. Treatment was associated with significant reductions from baseline in monthly migraine days and monthly headache days by 4.3 to 12.9 and 3.1 to 13.9, respectively. These values were numerically greater than those reported in most galcanezumab RCTs. Significant decreases from baseline were evident within the first month of treatment, and efficacy was maintained throughout the follow-up periods, ranging from 3 to 12 months. Galcanezumab was also associated with improvements in other efficacy end points, including decreased headache pain intensity, reduction in analgesic use, and improvements in daily functioning and quality of life. Functionality scores, as assessed by the Migraine Disability Assessment Scale questionnaire, decreased by 27 to 75 points from baseline at 3 to 12 months. Galcanezumab was associated with a low discontinuation rate and higher rates of persistence compared with standard migraine preventive treatments. Conclusions The results provide complementary data that galcanezumab is effective across the diverse patient populations observed in routine clinical practice.

Background Obsessions, compulsions, and stereotypes are common psychopathological manifestations of obsessive-compulsive, psychotic, and autism spectrum disorders (ASDs). These nosological entities may be present in comorbidity, with relevant clinical difficulties in the differential diagnosis process. Moreover, ASDs are a complex group of disorders, with a childhood onset, which also persist into adulthood and present heterogeneous symptom patterns that could be confused with psychotic disorders. Methods and Results We report a case of a 21-year-old man characterized by sexual and doubt obsessions; disorganized, bizarre, and stereotyped behaviors and compulsions; and social withdrawal, inadequate social skills, visual dispersions, and hypersensitivity to light stimuli. Obsessive and compulsive features were initially included within the differential diagnosis of psychotic and obsessive-compulsive spectrum disorders. However, aforementioned psychopathological elements did not improve when multiple antipsychotic drugs (olanzapine, haloperidol, and lurasidone) were administered in the hypothesis of schizophrenia and even worsened with clozapine therapy at a dose of 100 mg/d. Obsessions and compulsions progressively reduced during the fluvoxamine 14-week treatment paradigm at a dose of 200 mg/d. Considering the persistent deficits in social communication and interactions as well as the restricted interests pattern, a differential diagnostic hypothesis of ASD was formulated, and it was then confirmed at the final evaluation at a third-level health care center. Conclusions We discuss similarities and differences in the psychopathology of obsessions, compulsions, and stereotypes in the previously mentioned disorders, to underline factors that can help in the differential diagnosis of similar cases, and consequently in the appropriateness of treatment choice.

Methods We present a detailed clinical, laboratory, electroencephalogram/magnetic resonance imaging description and a 4-month follow-up of a case of stroke and provoked seizures as manifestation of angel's trumpet intoxication. Results/discussion A 76-year-old woman presented with stuporous state evolving in 48 hours in bilateral mydriasis, vomiting, global aphasia, confusion, and stereotyped movement. An interictal electroencephalogram, performed 72 hours later, showed frequent generalized epileptiform discharges, and a brain magnetic resonance imaging revealed 2 small subcortical lesions in the right frontal lobe on diffusion weighted imaging sequences. When completely recovered, she could tell that she had mistaken angel's trumpet flowers for pumpkin flowers, so she had eaten them. Conclusions Angel's trumpet intoxication is a neurological emergency that deserves attention of both the media in matter of plant poisoning and the scientific forums because of the high lethal potential to better choose the diagnostic and therapeutic process.

Parkinson disease (PD) is a neurodegenerative disorder, characterized by the excellent response to l-dopa and by asymmetry of neurological signs. The aim of the present study is to investigate a possible relationship between responsiveness to l-dopa in patients with PD and asymmetry detected by single photon emission computed tomography (SPECT) with [I]FP-CIT (DaTSCAN).We performed a retrospective study in 20 patients with PD never previously exposed to l-dopa, who had undergone (1) a short-term l-dopa test with l-dopa/carbidopa 250/25 mg to quantify dopaminergic responsiveness, and (2) a SPECT with DaTSCAN to assess the degree of nigrostriatal neuronal degeneration. We estimated the magnitude and the duration of the response to l-dopa test as well as the striatal asymmetry index (SAI) detected by SPECT with DaTSCAN.At l-dopa short-term test, most patients showed at least a mild response to the drug, and only 3 patients presented no response. Overall, the Unified Parkinson's Disease Rating Scale-Motor Examination section score at baseline was 24.9 ± 8.2, and that at peak was 21.2 ± 8 with a magnitude of the response scoring 16 ± 13.9%; the duration was 254 ± 91.2 minutes. The caudate and putamen uptakes of DaTSCAN were lower contralaterally to the most affected side. A significant positive correlation between the SAI and the magnitude of the response to l-dopa was found (r = 0.64, P = 0.002). Linear regression model provided an increase of 0.76 units of magnitude of l-dopa response every SAI unit.Asymmetry resulted positively related to the magnitude of the response to l-dopa short-term test and may be usefully used to predict dopaminergic responsiveness in patients with PD.

Sexual dysfunction is a common adverse effect in selective serotonin reuptake inhibitors users. We report a case of substantial improvement in sexual function with cariprazine at very low dosage.

Although lithium is widely used as a first-line treatment for mood disorders, its mood-stabilizing effects remain not fully understood. A growing body of data are stressing that lithium seems to show broader properties, including neuroprotective effects. Lithium's ability to inhibit glycogen synthase kinase 3β, an enzyme that participates in the phosphorylation of τ, a microtubule-associated protein, stimulated interest in its possible therapeutic role in Alzheimer disease and other neurodegenerative disorders. Preliminary data also support exploration of lithium's potential therapeutic role in multiple sclerosis, an autoimmune disorder that is associated with co-occurring mood disorders. Lithium is associated with teratogenic risks to the developing fetus; however, recently revised downward estimates of its teratogenic risk of causing fetal cardiac malformation suggest that its potential therapeutic benefit to both mothers with bipolar disorder and their offspring should be considered in at least some cases. A 43-year-old woman previously diagnosed with bipolar disorder and MS was treated with lithium and thyroid hormone supplementation as her sole medications during her pregnancy. The patient remained euthymic throughout her pregnancy and over the course of her 5-year follow-up evaluations on this medication regimen. In addition to her stable mood, there has been no symptomatic progression or relapse of her MS, and her daughter continues to develop normally.The case supports consideration of balancing lithium's mood-stabilizing benefit with its known teratogenic risk during pregnancy. The case also supports exploration of possible additional benefit in the context of MS co-occurring with bipolar disorder.

Polyneuropathy (PN) is a frequent and significant clinical manifestation of multiple myeloma that may be observed at onset of disease or induced during treatment as a therapy-related complication. Polyneuropathy may be a relevant issue in myeloma patients owing to its significant impact on the quality of life, considering that it may lead to dose reduction or treatment discontinuation. The present retrospective study intended to evaluate efficacy of pregabalin (PGB) in treatment of PN in multiple myeloma patients.Medical charts of 108 consecutive PN myeloma patients were reviewed. Data regarding the tumor history and therapy as well as the clinical and neurophysiological examinations 6 months before and after initiation of PGB therapy were collected.Thirty-eight medical charts had all the requested information. All patients (n = 38) underwent bortezomib-based treatment; 19 were previously treated and 19 were treatment naive. At first neurologic visit, all patients had PN symptoms (grade 2 of National Cancer Institute-Common Toxicity Criteria) without relevant pain. Neurophysiological evaluation showed a significant decrease in sensory nerve action potential amplitude (P = 0.006), conduction velocity (P = 0.006), and distal latency (P = 0.03) of sensory nerves between the first and the last neurological examination, in all patient population. Similar results were observed in treatment-naive patients, when the study cohort was stratified according to previous treatment. On the contrary, no significant differences were found between the first and the last neurophysiological follow-up evaluation in previously treated patients. Six months after PGB treatment, all patients reported disappearance of neurological symptoms (grade 0 National Cancer Institute-Common Toxicity Criteria).In this retrospective study, improvement in neurological symptoms during PGB therapy was observed in the total population, despite the presence of a distal, sensory axonal neuropathy, as evidenced by neurophysiological examination.

The aim was to evaluate plasma and cerebrospinal fluid (CSF) nimodipine concentrations in patients with aneurysmal subarachnoid hemorrhage and their correlation with clinical outcome.Nimodipine infusion was started at 1 mg/h and increased up to 2 mg/h and continued up to 21 days in surviving patients. Arterial and CSF samples were collected at least after 24 hours of stable nimodipine dosing. Delayed cerebral ischemia and vasospasm were documented by new neurological deficits and neuroimaging. The clinical outcome was assessed at 9 months by the modified Rankin scale.Twenty-three patients were enrolled. Nimodipine dose was 13 to 38 μg/kg per hour. Nimodipine arterial and CSF concentrations were 24.9 to 71.8 ng/mL and 37 to 530 pg/mL, respectively. Dose did not correlate with arterial or CSF concentrations. Arterial concentrations did not correlate with corresponding CSF concentrations. Doses and arterial concentrations did not correlate with the clinical outcome and were not associated with the occurrence of delayed cerebral ischemia. However, patients with no significant disability after 9 months of hemorrhage showed significantly higher CSF nimodipine concentrations (P = 0.015) and CSF-to-plasma ratios (P = 0.011) compared with patients who showed some degree of disability or who died.Cerebrospinal fluid nimodipine concentrations measured during hospital drug infusion showed a correlation with long-term clinical outcome in patients with aneurysmal subarachnoid hemorrhage. These very preliminary data suggest that CSF concentrations monitoring may have some value in managing these patients.

Catatonia is a rare condition that can occur in developmental disorders, but it is more frequently seen in schizophrenia. Recently, a high prevalence of cerebrospinal fluid abnormalities including the detection of antineuronal autoantibodies has been observed in psychotic patients. Among these autoimmune encephalopathies associated with a psychiatric condition, a great deal of attention has been paid to anti-N-methyl-D-aspartate receptor (NMDAr) encephalitis, which may present, among other things, symptoms such as catatonia, which therefore imposes a differential diagnosis with respect to the early psychosis. The aim of our study was to describe the clinical characteristics of 4 cases with catatonic symptoms to understand the differences between the psychotic symptoms due to a type of encephalitis anti-NMDAr and the psychotic symptoms without anti-NMDAr.

Bipolar disorder (BD) patients with a comorbid substance use disorder (SUD) are notoriously difficult to treat. Atypical antipsychotics (AAPs) are widely prescribed in BD, but their efficacy in patients with comorbid SUD is still debated. The aim of the present article is to systematically review the literature findings on the efficacy and safety of AAPs in BD patients with comorbid SUD.We searched PubMed to identify original studies focused on the treatment of dual diagnosed BD with AAPs.Ten articles met our inclusion/exclusion criteria, involving a total of 969 subjects, 906 affected by BD and 793 with comorbid SUD: 4 were randomized controlled trials, 4 were open label trials and 2 were observational studies, published between 2002 and 2017. The most commonly abused substances were alcohol and cocaine. The AAPs used to treat patients were quetiapine (n = 337), asenapine (n = 119), olanzapine (n = 80), risperidone (n = 62), and aripiprazole (n = 48). In terms of safety, AAPs were usually well tolerated. Atypical antipsychotics were usually efficacious on acute mood symptoms, whereas their impact on substance-related issues was reported only in those studies without a placebo comparison.According to our results, even though AAPs are widely used and efficacious in treating the clinical symptoms of BD, there are not enough data to suggest their adjunctive benefit on craving and substance consumption.

We aimed to assess the potential relationship between intrasubject 9-tetrahydrocannabinol/cannabidiol (THC/CBD) oromucosal spray plasma profiles and clinical effects elicited by subacute dosing in chronically treated patients with multiple sclerosis (MS).The study design was pilot, single center, open, and prospective. The patients were challenged with a morning test dose of 2 THC/CBD sprays at a 15-minute interval. Venous blood samples were collected before the first spray administration and every 30 minutes after the second spray, until 240 minutes postdosing. Patients rated their spasticity by the Numerical Rating Scale (NRS) simultaneously with blood drawings. Postural and motor tests were performed before the first spray and 90 and 180 minutes thereafter.Twelve patients were recruited. Peak plasma concentrations of THC/CBD largely varied among patients, from 0.60 to 13.29 ng/mL for THC and 0.55 to 11.93 ng/mL for CBD. Time to peak plasma concentrations ranged from 150 to 240 minutes for THC and 90 to 240 minutes for CBD. Patients' NRS serial scores decreased after dosing, from a median value of 6 to 3.5 (P < 0.001). A significant inverse correlation was observed between median intrasubject repeated NRS scores and corresponding median values of both THC (P < 0.01) and CBD (P < 0.002) plasma concentrations. No significant effect of cannabinoids dosing could be appreciated according to posturographic and motor tests.Our kinetic dynamic findings from THC/CBD oromucosal spray are the first obtained in real MS patients. Although preliminary, they suggest that subacute dosing might elicit a subjective clinically significant effect on MS-related spasticity, paralleling cannabinoids measurable plasma concentrations.

Hyperkinetic movement disorders may be difficult to treat, but cases where patients respond to alcohol and/or drugs with similar effects have been described. We report the case of a 64-year-old man with tardive dyskinesia characterized by severe uncontrolled dystonic and myoclonic jerks of the face, shoulders, and arm and forearm muscles, which improved with oral sodium oxybate. Our case suggests the possibility to test sodium oxybate in patients with severe, drug-resistant hyperkinetic syndromes, especially when they are known to improve with alcohol.

Generic antiepileptic drugs represent a measure to maximize cost saving. Levetiracetam (LEV) is one of most commonly used and effective antiepileptic drugs. The objective of our work was to demonstrate the effectiveness and safety of overnight switch from monotherapy with Keppra (original drug) to epitiram (generic drug) at the same dose.In our observational study, we consecutively enrolled 37 seizure-free patients with epilepsy who expressed the wish to switch to a generic drug for economic reasons. During the 6-month evaluation period, we assessed treatment efficacy, tolerability, compliance, and intersubject variability of LEV serum concentration. At each visit, clinical and neurological examination, scales, video-electroencephalogram, and blood sample analysis to evaluate LEV plasma level were performed.A total of 36 of 37 enrolled patients switched from Keppra to epitiram, which was administered at the same dose in monotherapy. Three of 36 patients dropped out during follow-up for adverse events. The other 33 subjects had neither seizures nor adverse events. No significant differences in electroencephalogram features and scale scores were revealed; the intersubject variability of LEV serum concentration did not differ significantly at follow-up evaluation (P = 0.53). All the patients expressed good clinical personal impression and continued to take epitiram. The switchback rate was 8 %.The switch from Keppra to epitiram was easy and safe in our population, and epitiram can be considered as effective and tolerable as Keppra. Only a slight, non-statistically significant variability in LEV serum concentration was documented after the switch from Keppra to epitiram. Larger epileptic populations should be studied to confirm these results.

Compulsive buying disorder (CBD) is a condition characterized by excessive preoccupations, impulses, and behaviors regarding buying, resulting in serious psychological, social, and financial problems. Even though it has not been included in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, "behavioral addictions" section, CBD is a hot topic in current clinical psychiatry, because of its relevant prevalence (at least 5% in adult populations) and severe effect on quality of life.The CBD shares some clinical features with substance-related and behavioral addictions, impulse control disorders, and obsessive compulsive disorder, and it is often comorbid with other psychiatric illnesses (especially depressive and anxiety disorders). The treatment of CBD is therefore difficult, and clear therapeutic guidelines are not yet available. Treating the comorbid disorders as the first-line approach, or combining drugs with different pharmacodynamic profiles, has been suggested to address this challenging condition.A 60-year-old woman affected by a severe form of CBD with comorbid major depressive disorder, resistant/intolerant to previous selective serotonin reuptake inhibitor treatments and only partially responder to mirtazapine, achieved a good clinical improvement adding bupropion.Combining 2 agents with different pharmacological profiles and mechanisms of action, such as bupropion and mirtazapine, could be a useful strategy in the management of complex CBD cases.

Epilepsy heavily affects the quality of life (QoL) of patients with brain tumor because in addition to taking treatments for the oncological illness, patients are required to live with the long-term taking of antiepileptic drugs (AEDs). The AEDs' adverse effects are common in these patients and can negatively influence their perceptions of their QoL.We conducted an observational pilot study in patients with brain tumor-related epilepsy to verify efficacy, tolerability, and impact on QoL and global neurocognitive performances of zonisamide (ZNS) in add-on.We recruited 13 patients (5 females, 8 males; mean age, 49.6 years) presenting uncontrolled seizures. At first visit and at final follow-up at 6 months, patients underwent neurological examination, evaluation of adverse events, and cognitive and QoL tests. A seizure diary was given.Eight patients underwent chemotherapy, 3 underwent radiotherapy, and 5 had disease progression. Mean dosage of ZNS at final follow-up was 300 mg/d.Of 9 patients who reached the sixth month follow-up, the mean weekly seizure number before ZNS had been 3.2 ± 5.0, and at final follow-up, the mean weekly seizure number was 0.18 ± 0.41 (P = 0.05).Compared with baseline, we observed stability in all cognitive domains, except for verbal fluency that significantly worsened.Results on QoL tests showed that QoL remained unchanged over time, which could indicate that ZNS did not influence the patients' perceived QoL.Zonisamide as add-on in our patients seems to be well tolerated and efficacious in controlling seizures. Despite having limitations represented by the fact that our study is observational, with a small study population and a short follow-up period, our results confirm that when choosing an AED, in addition to efficacy, the drug's effect on patients' QoL also needs to be considered, especially for patients facing many psychosocial challenges, such as those with brain tumor-related epilepsy.

Traditional pharmacotherapy has undoubtedly improved the outcome of patients with psychiatric disorders, but partial efficacy or poor tolerability persists in a number of these subjects. Among different compounds, zonisamide has been used to address unmet needs of standard pharmacotherapy. The purpose of the present article is to provide a review about the use of zonisamide for the treatment of psychiatric conditions.A research in the main database sources has been conducted to obtain an overview of the use of zonisamide in psychiatric disorders or associated conditions (obesity and smoking cessation).Most available data indicate the possible effectiveness of zonisamide for the treatment of acute phases of bipolar disorder, binge-eating disorder (BED), alcohol misuse, and obesity. A further assessment of the safety and tolerability of zonisamide is made necessary by the fact that, with the exception of BED, for all other disorders at least some data come from studies with combined pharmacological therapies.Zonisamide may have some utility, especially as an adjunctive therapy, for the management of acute phases and weight gain in bipolar disorder and for prevention of alcohol misuse. Preliminary evidence indicates zonisamide as a candidate compound for the treatment of BED and obesity. However, open-label design and small sample sizes of most available studies prevent from drawing sound conclusions about the utility of this compound in psychiatry.

Several in vitro data have reported negative interference by dopamine-agonists on the expression of dopamine transporter (DAT), whereas the majority of imaging studies have shown that neither L-dopa nor dopamine-agonists interfere with DAT availability. As yet, there are no in vivo studies on DAT expression after treatment with rotigotine.We evaluated presynaptic nigrostriatal function in 8 patients with de novo Parkinson disease (age, 59 ± 6.2 years; male/female sex, 5/3) using 123-I- N-ω-fluoropropyl-2-β-carbomethoxy-3-β-(4-iodophenyl)nortropane (FP-CIT) single-photon emission computed tomography before and after 3 months of treatment with rotigotine (mean dose, 7.75 ± 1.98 mg). For data analysis, specific (left and right caudate, left and right putamen) to nonspecific (occipital cortex) binding ratios, putamen-to-caudate ratios, and asymmetry indices were calculated.After rotigotine, motor symptoms improved in all patients (Unified Parkinson Disease Rating Scale III mean score, 11.88 ± 2.59 vs 7.63 ± 1.92 on therapy; P = 0.0022). Striatal FP-CIT levels showed a significant improvement in every patient at the follow-up scan. Comparisons between before and after treatment in the whole group revealed a significant improvement in FP-CIT uptake in both caudate and putamen (P < 0.001 in each nucleus). Putamen-to-caudate ratio and asymmetry indices did not show any significant difference before and after treatment.Although the study population was small, we found DAT overexpression after chronic treatment with rotigotine, presumably related to its pharmacological profile. The DAT upregulation by rotigotine in an opposite direction with respect to early Parkinson disease compensatory mechanisms might reduce the risk of dyskinesia, but it could imply less motor benefit because of less stimulation by the dopamine itself on dopaminergic receptors.

To evaluate the severity of wearing-off and dyskinesia in patients with complicated Parkinson disease (PD) after switching L-dopa oral therapy from a "pulsatile" administration, consisting in intermittent multiple daily small doses of the drug, to a "pulse" administration, consisting in standard oral doses given at specific interdose intervals.Thirty-four PD patients with motor complications were monitored twice with standardized waking day motor status evaluations using the Unified Parkinson Disease Rating Scale-Motor Examination (UPDRS-ME) and the Abnormal Involuntary Movement Scale (AIMS) after switching L-dopa administration modality from "pulsatile" to "pulse." To quantify predictable motor fluctuations, a Wearing Off Index was computed based on changes in treatment response magnitude.On the whole, after switching from "pulsatile" to "pulse" administration, there was a reduction in number of L-dopa daily doses and an increase in the amount of the dosage of the single doses, AIMS maximum score decreased without increasing motor disability. More specifically, in predominant fluctuating patients, there was a significant reduction in UPDRS-ME average score as well as in Wearing Off Index. In predominant dyskinetic patients, there was a significant reduction in average and maximum AIMS scores with no changes in average and maximum UPDRS-ME scores.Switching L-dopa therapy from "pulsatile" to "pulse" modality may reduce the severity of wearing-off and dyskinesia in complicated PD.

Treatment-resistant schizophrenia (TRS) is a condition characterized by intense symptom severity and poor response to different antipsychotic agents. The first therapeutic option in TRS is clozapine, but often high/medium doses are not tolerated. Adding an oral antipsychotic to low doses of clozapine is a promising strategy in the management of TRS. On the contrary, there are few data on combined clozapine/long-acting injectable (LAI) medications, and none on clozapine/LAI-aripiprazole.A 21-year-old male schizophrenic patient, resistant to several oral and LAI medications, partially improved after clozapine 300 mg/d treatment. Unfortunately, he also reported excessive sedation and an episode of myoclonus, so clozapine was reduced to 150 mg/d, but no additional benefits were observed. Subsequently, LAI-aripiprazole (first 200 mg/mo, then 400 mg/mo) was added, and the patient's conditions dramatically improved over time. After 1 year of observation, symptoms reduction was 50% or greater, without significant adverse events.Clozapine use in TRS is often reduced or delayed due to the fear of serious adverse effects. Adding LAI-aripiprazole to low doses of clozapine may be a useful therapeutic option to obtain a good efficacy/tolerability balance.

Despite optimal medical treatment, up to 30% of patients with epilepsy continue to experience recurrent seizures, and the challenge for new more efficacious and better-tolerated drugs is continuing. New antiepileptic drugs include the evolution of preexisting drugs and new compounds identified through the investigation of additional molecular targets, such as SV2A synaptic vesicle protein, voltage-gated potassium channels, ionotropic and metabotropic glutamate receptors, and gap junctions.We report the available data about different classes of molecules that are in the pipeline for treatment of focal epilepsy. We will present data available on drugs derived from the evolution of preexisting anticonvulsants. We will then report the results on clinical trials performed with new compounds identified through the investigation of additional molecular targets.The challenge for new, more efficacious, more specific, and better-tolerated drugs is continuing and a better knowledge of mechanisms underlying epilepsy should represent the guide for future research. The ultimate goal of treatment should be not only to render the patients seizure free but also to improve the quality of life and reduce costs of medical care.

Sertraline is a selective serotonin reuptake inhibitor used as an antidepressant and antipanic agent in children and adolescents. Sertraline is well tolerated and its safety profile in overdose is favorable. However, sertraline overdose may cause a toxic hyperserotonergic state known as serotonin syndrome (SS). Serotonin syndrome may be misdiagnosed in children because it has been reported mostly in adults. In the present case report, we describe a 16-year-old female patient who ingested 2000 mg of sertraline to attempt suicide. The patient showed symptoms and signs suggestive of SS, characterized by an asynchronicity between organic and psychiatric symptoms. In addition, the patient showed a variability of psychiatric symptoms through time. Thirteen hours after sertraline overdose, she was poorly cooperative with poverty of speech and marked emotional tension, but she was oriented in space and time and was able to remember what happened to her and to reconstruct the dynamics of the fact. Twenty-four hours after sertraline overdose, the patient developed a delusion of reference associated with intense anxiety and depressed mood. In the present case report, we discuss the pathophysiologic mechanisms of the observed clinical manifestations and propose an observation period for sertraline overdose in children and adolescents that is sufficiently long (at least 72 hours) even in the absence of unstable vital signs.

Premenstrual dysphoric disorder (PMDD) is a disabling condition affecting approximately 2% to 8% of women during reproductive age. It has been recently included in the mood disorder section of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, but its treatment as a primary psychiatric illness is still debated, because of the high prevalence of other mental disturbances in PMDD patients. On the other hand, clear clinical guidelines for PMDD patients not suffering from comorbid mental conditions are not yet available. The aim of the present study was therefore to systematically review the original articles pertaining to the treatment of PMDD in adult women free of any current or previous psychiatric comorbidity.We searched PubMed to identify published studies on PMDD, including randomized controlled trials, open-label trials, and case series or case reports involving adult women with no history of comorbid mental conditions. The search was conducted in April 2015.We found 55 studies fulfilling our inclusion criteria, 49 of them focused on pharmacological/chemical agents and the remaining 6 on nonpharmacological interventions.Based on the results of our qualitative synthesis, the best therapeutic option in the treatment of adult PMDD patients free of other mental disorders are selective serotonin reuptake inhibitor antidepressants (especially paroxetine and fluoxetine) and low doses of oral estroprogestins. Other interventions, such as light therapy, cognitive behavioral therapy, food supplements, and herbal medicines, showed promising effects, but other investigations are needed to confirm their efficacy.

This was the first 12-week, open-label, uncontrolled trial aimed at exploring the efficacy of acetyl-L-carnitine (ALC) add-on pharmacotherapy on clinical symptoms and cognitive functioning in 15 schizophrenia patients with suboptimal clinical response despite receiving clozapine (CLZ) monotherapy at the highest tolerated dosage.After clinical (Positive and Negative Symptoms Scale [PANSS]) and neuropsychological (Wisconsin Card Sorting Test, Stroop Color-Word Test, Verbal Fluency Test) assessments, patients received 1 g/d of ALC for 12 weeks.A final sample of 9 subjects completed the study. Acetyl-L-carnitine augmentation of CLZ significantly reduced only PANSS domains "positive" (P = 0.049); at end point, only 2 subjects (22.2% of the completers) reached a minimal improvement (25% reduction in PANSS total score). No significant differences emerged in cognitive performances at the end of the study; effect sizes were small in each explored cognitive dimension.The findings provide preliminary evidence that ALC added to ongoing CLZ treatment appeared to be ineffective to improve symptoms in schizophrenia patients who have failed to respond sufficiently to CLZ. Further trials with adequately powered methodology are needed to identify which augmentation strategies are more effective in schizophrenia patients showing a suboptimal response to CLZ.

A paradoxical effect of antiepileptic drugs was defined as an increased seizure frequency or severity occurring shortly after introducing a drug considered effective for that kind of epilepsy. In addition, this effect should occur at nontoxic drug serum levels. So far, pathophysiological mechanisms underlying this phenomenon have not been clarified. Recent evidence suggests that the variability of drug effects may depend on precise intrinsic properties of dynamic networks involving the drug and its binding site. Although several reports of paradoxical seizure exacerbation have been reported for levetiracetam (LEV), a possible association with focal cortical dysplasia has never been described nor investigated. In this report, we document a paradoxical effect induced by LEV monotherapy in a patient with type II focal cortical dysplasia at LEV serum levels within the therapeutic range. A hint of pathophysiological hypothesis underlying this potential relationship will be also suggested.
