REVIEW
Bridget L Hopewell, Cristen Paige, David O Francis
Vocal tremor is a neurologic disorder with myriad etiologies (eg, Parkinson disease, medications, or essential tremor). Vocal tremor can limit intelligibility and social interaction and can result in isolation in nonprofessional voice users. In a professional singer whose entire career is based on voice quality, onset of a vocal tremor is devastating. We report a case of sudden-onset vocal tremor that impeded a young professional singer's ability to perform and record her album. The etiology was determined to be a medication side effect of lamotrigine; a reaction that has not been previously reported...

We sought to examine the risk of psychiatric symptoms associated with a first prescription for specific antiepileptic drugs (AEDs) used in monotherapy in a general cohort of patients with epilepsy. We used The Health Improvement Network database (comprising the years 2000-2012) to identify incident patients with epilepsy. The index date was that on which they met the case definition for epilepsy, and analyses only included patients who remained on monotherapy or received no AED therapy following diagnosis to avoid confounding by polytherapy...

OBJECTIVE: Despite numerous treatments for epilepsy, over 30% of patients remain resistant to available antiseizure drugs (ASDs). Thus, there is a strong need for more effective ASDs for these individuals. Early ASD discovery has historically relied on acute in vivo seizure models (maximal electroshock, subcutaneous pentylenetetrazol, 6 Hz), which lack the pathophysiology that defines chronic epilepsy. Etiologically relevant rodent models of pharmacoresistant epilepsy exist (eg, phenytoin (PHT)- and lamotrigine (LTG)-resistant amygdala-kindled rat and focal kainic acid mouse), but these models are resource- and labor-intensive and thus unsuitable for frontline ASD discovery...

Background Valproate is a widely prescribed antiepileptic drug for generalized epilepsies, due to the extensive knowledge on its efficacy since it is on the market for many decades. However, a large number of new antiepileptic medicines was introduced into clinical practice and may be better options for treatment, considering that these medicines differ in terms of efficacy spectrum. Despite extensive research, questions regarding which medicine would constitute the first option for the monotherapy treatment of generalized epilepsy remain...

BACKGROUND: Pregnant women with epilepsy on antiepileptic drugs (AEDs) may experience a reduction in serum AED levels. This has the potential to worsen seizure control. OBJECTIVE: To determine if, in pregnant women with epilepsy on AEDs, additional therapeutic drug monitoring reduces seizure deterioration compared with clinical features monitoring after a reduction in serum AED levels. DESIGN: A double-blind, randomised trial nested within a cohort study was conducted and a qualitative study of acceptability of the two strategies was undertaken...

OBJECTIVES: Eslicarbazepine acetate (ESL) is a once-daily (QD) oral antiepileptic drug (AED) for focal-onset seizures (FOS). Pharmacokinetic (PK) and pharmacodynamic (PD) models were developed to assess dose selection, identify significant AED drug interactions, and quantitate relationships between exposure and safety and efficacy outcomes from Phase 3 trials of adjunctive ESL. METHODS: Eslicarbazepine (the primary active metabolite of ESL) population PK was evaluated using data from 1351 subjects enrolled in 14 studies (11 Phase 1 and three Phase 3 studies) after multiple oral doses ranging from 400 to 1200 mg...

PURPOSE: Hyponatremia induced by antiepileptic drugs is common, but detailed evidence is lacking. This can be problematic for the treating neurologist confronted with a patient with severe hyponatremia in need of an alternative drug. The objective of this study was to examine the association between individual antiepileptic drugs and hospitalization due to hyponatremia. METHODS: This was a register-based case-control study of patients in the general Swedish population...

REVIEW

Since the inception of clinical teratology, the vast majority of scientific work has focused on identification of drugs and environmental agents causing malformations in humans as a dichotomous variable (i.e. yes or no), as well as the relative and absolute risks of such occurrences. Generally, the dose dependency of such events has not been investigated. With the establishment of large pregnancy databases, dose-dependence relationships are being uncovered for increasing numbers of medications, including valproic acid, carbamazepine, phenobarbital, lamotrigine, topiramate, and lithium...

WHAT IS KNOWN AND OBJECTIVE: Toxic prolongation of the QRS interval most often results from blockade of cardiac voltage-gated sodium channels and manifests on electrocardiogram with a right bundle-branch block-like morphology. Rarely, a left bundle-branch block (LBBB) morphology has been reported. CASE REPORT: We report a case of transient LBBB resultant from ingestion of lamotrigine and citalopram which was refractory to sodium bicarbonate therapy and eventually resolved spontaneously...

Background: Prepulse inhibition (PPI) of the acoustic startle reflex is an operational measure of sensorimotor gating. The findings on PPI deficits in bipolar disorder (BD) are inconsistent among studies due to various confounding factors such as gender. This study aimed to assess sensorimotor gating deficits in patients with BD stratified by gender and state (depressed/euthymic), and to explore related clinical variables. Methods: Subjects were 106 non-manic BD patients (26 BD I and 80 BD II; 63 with depression and 43 euthymic) and 232 age-, gender-, and ethnicity-matched (Japanese) healthy controls...

Andrew Levy, Manjit S Matharu
Short-lasting unilateral neuralgiform headache attacks (SUNHA) is characterized by strictly unilateral trigeminal distribution pain that occurs in association with ipsilateral cranial autonomic features. There are two subtypes: short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA). These disorders are rare but highly disabling. The management of SUNHA can be challenging...

INTRODUCTION: Women with epilepsy have increased risk of complications in pregnancy with consequences for the mother and child. There are no studies on the influence of parity on complications in women with epilepsy. MATERIAL AND METHODS: This was a population-based cohort study of all first and second births in the Medical Birth Registry of Norway 1999-2013. Risks were estimated and complication rates were compared in distinct women with epilepsy treatment categories...

The potential endocrine disrupting effects of the commonly prescribed anti-epileptic drug lamotrigine (LAM) was investigated using the H295R steroidogenic in vitro assay and computational chemistry methods. The H295R cells were exposed to different concentrations of LAM and a multi-steroid LC-MS/MS method was applied to quantify the amount of secreted steroid hormones. LAM affected several steroid hormones in the steroidogenesis at therapeutic concentrations. All progestagens as well as 11-deoxycorticosterone and corticosterone increased 100-200% with increasing concentrations of LAM suggesting a selective inhibitory effect of LAM on CYP17A1, in particular on the lyase reaction...

Psychiatric disorders are more common in patients with epilepsy than in the general population. The aims of the study were to assess the frequency and type of psychotropic drug usage in patients with epilepsy, to assess the risk factors for their use, and to assess their proconvulsive potential and the risk of interactions with antiepileptic drugs. This 20-month prospective study included patients treated at the university hospital outpatient clinic. Psychotropic drugs have been classified according to the Anatomical Therapeutic Chemical Classification System...

Carbendazim is a fungicide commonly used as active substance in plant protection products and biocidal products, for instance to protect facades of buildings against fungi. However, the subsequent occurrence of this fungicide and potential endocrine disruptor in the aqueous environment is a major concern. In this study, high resolution mass spectrometry shows that carbendazim can be detected with an increasing abundance from the source to the mouth of the River Rhine. Unexpectedly, the abundance of carbendazim correlates poorly with that of other fungicides used as active ingredients in plant protection products (r2 of 0...

BACKGROUND: Evidence for the comparative teratogenic risk of antiepileptic drugs is insufficient, particularly in relation to the dosage used. Therefore, we aimed to compare the occurrence of major congenital malformations following prenatal exposure to the eight most commonly used antiepileptic drugs in monotherapy. METHODS: We did a longitudinal, prospective cohort study based on the EURAP international registry. We included data from pregnancies in women who were exposed to antiepileptic drug monotherapy at conception, prospectively identified from 42 countries contributing to EURAP...

We summarize evidence supporting contemporary pharmacological treatment of phases of BD, including: mania, depression, and long-term recurrences, emphasizing findings from randomized, controlled trials (RCTs). Effective treatment of acute or dysphoric mania is provided by modern antipsychotics, some anticonvulsants (divalproex and carbamazepine), and lithium salts. Treatment of BD-depression remains unsatisfactory but includes some modern antipsychotics (particularly lurasidone, olanzapine + fluoxetine, and quetiapine) and the anticonvulsant lamotrigine; value and safety of antidepressants remain controversial...
