OBJECTIVES: 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. METHODS: 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...

OBJECTIVES: The adenosine A2A antagonist istradefylline has been used to treat Parkinson disease (PD) with symptoms of wearing-off since 2013 in Japan. Previous randomized controlled trials of istradefylline compared with placebo included PD patients experiencing an average daily OFF time of more than 2 hours. The purpose of this study is to assess the efficacy of 20 mg/d istradefylline in PD subjects experiencing an average daily OFF time of 3 hours or less. METHODS: Fifteen patients were enrolled into this retrospective study...

OBJECTIVES: Obsessive-compulsive disorder (OCD) is notably a comorbid disorder in patients with schizophrenia. This study aimed to evaluate clinical features and correlates of early onset patients with schizophrenia with OCD. METHODS: In the present study, we included 10 patients with both schizophrenia and OCD and 19 patients with schizophrenia without OCD. The mean antipsychotic doses the patients needed for treatment are standardized as chlorpromazine equivalent dose...

OBJECTIVE: This study aims to report the case of a patient with recurrent subdural hemorrhage (SDH) who was administered tissue plasminogen activator through a subdural drain to enhance drainage and prevent recurrence. METHODS: An 85-year-old man was treated for subacute over chronic SDH that kept on reaccumulating despite serial twist drill drainage, burr hole drainage, and craniotomy. No coagulopathy was identified with adequate blood pressure control. RESULTS: Treatment with tissue plasminogen activator resulted in successful drainage of the SDH, and the patient had no further recurrence at 9-month follow-up...

OBJECTIVE: The aim was to evaluate fingolimod safety and patient profiles in a real-world setting in Buenos Aires, Argentina. METHODS: Relapsing-remitting patients with multiple sclerosis who had been prescribed fingolimod and at least 18 months or more of follow-up were included. Demographic, clinical, and safety issues were described during first dose and follow-up. RESULTS: A total of 145 patients were included, 68% female; mean age, 30 ± 10...

Mihir Parekh, Gopal Krishna Dash, Isthiaque Ahamed
A 74-year-old man with peripheral neuropathy due to diabetes presented with deliberate ingestion of 450 mg of pregabalin (PBG) over a period of 8 hours followed by altered mental status. A bedside electroencephalogram was performed to rule out nonconvulsive status epilepticus, which showed continuous triphasic waves (TWs) with slow background activity. He recovered after 48 hours of stopping PBG, and his repeat electroencephalogram after 72 hours did not show any TWs. We present a rare case of PBG-induced TWs thereby highlighting the extent of the etiologic spectrum of TWs and discussing the literature related to this association...

BACKGROUND: In Japan, selegiline has been approved for combination therapy with levodopa for Parkinson disease (PD). We conducted a trial of selegiline monotherapy for early PD. METHODS: In this 12-week controlled phase III trial, a total of 292 subjects were randomized to receive placebo (n = 146) (full analysis set 140) or selegiline (n = 146) (full analysis set 139). The primary outcome measure was the change in the Unified Parkinson Disease Rating Scale part I + II + III total score from baseline to the final visit...

Dropped head (DH) syndrome is a phenomenon of disproportionate neck anteflexion that has been reported in patients with Parkinson disease (PD). Antiparkinsonian medications such as dopaminergic agonists (DAs) have been implicated in the onset of DH episodes. Deep brain stimulation (DBS) is an important therapeutic option after the failure of conventional treatments such as DA therapy in patients with PD. Here, we report the case of a patient with rigid-akinetic parkinsonism who developed DH syndrome after the initiation of DA treatment...

OBJECTIVE: The aim of this study was to report worsening of Tourette syndrome (TS) in 2 patients treated with varenicline. BACKGROUND: Abnormal dopaminergic signaling is likely involved in the pathophysiology of TS. Varenicline is a partial α4β2 nicotinic acetylcholine agonist that enhances dopamine release. Therefore, the use of varenicline may influence tics in patients with TS. METHOD: We analyzed and described 2 case studies on patients with significant worsening of tics after treatment with varenicline...

OBJECTIVE: This study aimed to compare the presence of agitation in traumatic brain injury patients treated with amantadine with those not treated with amantadine in the intensive care unit (ICU). METHODS: This was a retrospective cohort study conduced in a trauma ICU of a tertiary care institution in the United States. Patients who received amantadine were compared with patients who did not receive amantadine. The primary outcome measure was the presence of agitation, defined as the Richmond Agitation Sedation Scale score of +2 or higher...

OBJECTIVES: Adverse neurologic outcome can be a debilitating complication after cardiac surgery. The aim of this study was to investigate the potential neuroprotective action of erythromycin, a well known antibiotic agent, regarding postoperative cognitive decline in patients undergoing cardiac surgery. METHODS: Forty patients scheduled for elective coronary artery bypass grafting surgery were prospectively randomly assigned in 2 groups: the erythromycin group (n = 19) who received erythromycin at a dose of 25 mg/kg before and after surgery and the control group (n = 21) who did not receive it...

Reversible corpus callosum splenial (CCS) lesions have been described in patients with varied etiologies. The most common causes of previously reported reversible focal lesions of the CCS are viral encephalitis, antiepileptic drug toxicity/withdrawal, and metabolic disorders. Intravenous immunoglobulin (IVIG) therapy is used for different immune-mediated diseases. It is generally safe, and serious adverse reactions are uncommon. We presented a rare case of disturbed consciousness with reversible CCS lesions after IVIG therapy for Guillain-Barre syndrome in an adult woman...

Divalproex was successfully used in a 7-year-old boy suffering from treatment-refractory school refusal complicated with a mood disturbance and anxiety. Divalproex had demonstrated a rapid effect in reducing school anxiety and improving school attendance after multiple failures of other agents. Divalproex may be an effective agent for treating school refusal in children with emotional and/or behavior disturbances.

Jose David Avila
Trazodone is a serotonin antagonist and reuptake inhibitor that is widely used for the treatment of depression and insomnia. Fatal overdose is rare and usually occurs when combined with other drugs or alcohol. Only a few lethal cases of pure trazodone overdose have been reported, all attributed to cardiotoxicity. We reported a 37-year-old woman who presented after ingesting 6.45 g of trazodone in a suicidal attempt. She was hyponatremic because of the syndrome of inappropriate antidiuretic hormone secretion and, shortly after, had a seizure and developed fatal cerebral edema...

Thomas Müller, Peter Riederer, Edna Grünblatt
BACKGROUND: Biogenic amines and monoamine oxidase inhibitors influence peripheral monoamine oxidase enzyme activity in chronic levodopa/dopa decarboxylase inhibitor-treated patients with Parkinson disease. Rasagiline is an irreversible inhibitor of monoamine oxidase B. Safinamide blocks this isoenzyme in a reversible fashion. OBJECTIVES: The aim of this study was to determine monoamine oxidase A (plasma) and B (platelets) enzyme activity in long-term levodopa-treated patients without and with additional oral intake of 50- or 100-mg safinamide or 1-mg rasagiline or first-time intake of rasagiline...

Ayse Kartal
Levetiracetam is an antiepileptic drug that has been used both as adjunctive therapy and monotherapy in pediatric patients with epilepsy. We report a patient with cerebral palsy and epilepsy who took 200 mg/kg per day of levetiracetam for 55 days with no apparent adverse effects. Four other cases of accidental overdose were found in the literature; none of these was associated with any apparent adverse effects. These findings suggest that, in at least some cases, levetiracetam doses much higher than the recommended maximum of 60 mg/kg per day can be administered without apparent adverse effects...
