Learning disabilities: analysis of 69 children

With this article we intend to demonstrate the importance of evaluation and follow up of children with learning disabilities, through a multidisciplinary team. As well as to establish the need of intervention. We evaluate 69 children, from Aline Picheth Public School, in Curitiba, attending first or second grade of elementary school, through general and evolutionary neurological examination, pediatric checklist symptoms, and social, linguistic and psychological (WISC-III, Bender Infantile and WPPSI-figures) evaluation. The incidence was higher in boys (84,1%), familiar history of learning disabilities was found in 42%, and writing abnormalities in 56,5%. The most frequent diagnosis was attention deficit and hyperactivity disorder, in 39,1%. With this program, we aimed to reduce the retention taxes and stress the importance of this evaluation, and, if necessary, multidisciplinary intervention in the cases of learning disabilities.

Δ9-THC Intoxication by Cannabidiol-Enriched Cannabis Extract in Two Children with Refractory Epilepsy: Full Remission after Switching to Purified Cannabidiol.

Animal studies and preliminary clinical trials have shown that cannabidiol (CBD)-enriched extracts may have beneficial effects for children with treatment-resistant epilepsy. However, these compounds are not yet registered as medicines by regulatory agencies. We describe the cases of two children with treatment-resistant epilepsy (Case A with left frontal dysplasia and Case B with Dravet Syndrome) with initial symptom improvement after the introduction of CBD extracts followed by seizure worsening after a short time. The children presented typical signs of intoxication by Δ9-THC (inappropriate laughter, ataxia, reduced attention, and eye redness) after using a CBD-enriched extract. The extract was replaced by the same dose of purified CBD with no Δ9-THC in both cases, which led to improvement in intoxication signs and seizure remission. These cases support pre-clinical and preliminary clinical evidence suggesting that CBD may be effective for some patients with epilepsy. Moreover, the cases highlight the need for randomized clinical trials using high-quality and reliable substances to ascertain the safety and efficacy of cannabinoids as medicines.

Menkes' disease: case report

Menkes disease is a rare neurodegenerative disorder due to an intracellular defect of a copper transport protein. We describe a 7 months male patient who presented with seizures, hypoactivity and absence of visual contact. The investigation disclosed pilli torti and thrycorrexis nodosa in the hair, low serum levels of both copper and ceruloplasmin, brain magnetic resonance study showed atrophy and white matter hypointensities on T1-weighted images, electroencephalogram reveals moderate background activity disorganization and epileptiform activity, and muscle biopsy with type 2 fiber atrophy. The clinical, laboratorial, genetic, muscle biopsy and neurophysiological findings in Menkes disease are discussed.A doenca de Menkes e uma rara desordem neurodegenerativa causada por defeito intracelular na proteina transportadora do cobre. Descrevemos um paciente de 7 meses, masculino, com crises convulsivas, hipoatividade e ausencia de contato visual. A investigacao demonstrou pilli torti e thrycorrexis nodosa; niveis sericos baixos de ceruloplasmina e cobre; RNM de crânio com atrofia e reducao de sinal da substância branca (imagens em T1); eletroencefalograma com moderada desorganizacao da atividade de base e atividade irritativa; e biopsia muscular com atrofia de fibras do tipo 2. As caracteristicas clinicas, laboratoriais, geneticas, biopsia muscular e estudo neurofisiologico na doenca de Menkes sao discutidas.

Reactivation of herpes simplex virus-1 following epilepsy surgery.

Purpose The present study reports a case of encephalitis due to herpes simplex virus-1 (HSV-1), following surgical manipulation of the site of a primary infection. Methods Herpes simplex virus-1 infection was confirmed by CSF PCR and DNA sequencing. Results The patient was an 11-year-old girl who required temporal lobe surgery for epilepsy. She had meningoencephalitis due to HSV at the age of 20 months, and she was treated with acyclovir. Three years later, the patient developed uncontrolled seizures that became more frequent and changed in character at 11 years of age. On the 12th postoperative day, she developed fever and seizures, and she was diagnosed with HSV-1 by positive CSF PCR. She was treated with acyclovir (30 mg/kg/day for 21 days). In this report, we describe the patient and review the relevant literature. Conclusion The authors stress the potential risk of reactivation of HSV encephalitis after intracranial surgery. Herpes simplex virus encephalitis must be considered in neurosurgical patients who develop postoperative seizures and fever.

Psychogenic nonepileptic seizures: an overview

Pyschogenic nonepileptic seizures (PNES) are common and potentially harmful - both physically and emotionally - events. They are often under or misdiagnosed. Not only neurologists managing epilepsy, but also generalists and ER physicians should be aware of its existence, preventing unnecessary tests, as well as, iatrogenic interventions. The assistance provided to these patients is often inadequate, even at larger and busier epilepsy centers. That clearly impacts on the prognosis of this condition, which is fairly difficult to manage per se, yet with the best possible quality of care, including well trained multiprofessional teams.

Right and left mesial temporal lobe seizures in one patient: Bona fide semiological, interictal, ictal, and MRI evidence

We present the case of a 36-year-old patient with bilateral independent manual automatisms associated with seizures coming independently from the left and right temporal lobes, as documented by surface EEG ictal recordings. An MRI showed evidence of bilateral mesial temporal sclerosis, more prominent on the right side. We speculate whether clinical semiology (along with the ictal EEG and imaging findings) discourages the pursuit of invasive monitoring, leading to more aggressive medical management in this particular case.

Uncontrolled headache induced by oxcarbazepine

Headache induced by acute exposure to a specific drug constitutes an idiosyncratic side effect. Metabolic imbalance appears as the leading aetiology, among several other hypotheses. Either primary headaches show a higher susceptibility to this idiosyncratic reaction or a drug-induced primary headache evolves in intensity and duration, becoming uncontrolled until the complete discontinuation of the drug in consideration. The goal of this study is to describe three patients diagnosed with migraine and epilepsy (both under control) who evolved into status migrainosus after the introduction of oxcarbazepine (OXC), as part of a switch off from carbamazepine (CBZ). Twenty-four to seventy-two hours following the switch, all patients developed intractable headache, despite the use of different symptomatic drugs. Complete recovery of the headache symptoms occurred only after OXC was discontinued. We discuss the potential mechanisms associated to OXC and status migrainosus, drug-induced headaches and uncontrolled headaches.

Analysis of frontal sharp transients in 32 neonatal polysomnography in healthy fullterm newborns

OBJECTIVE To identify and quantify frontal sharp transients found in neonatal polysomnography of healthy full term newborns in each stage of the sleep-wake cycle within the first 48 hours of life. METHOD The EEG from healthy term 32 newborns, legal age of two days and with adequate monitoring during pregnancy. Frontal sharp transients (FST) were quantified, according to synchronous or asynchronous, in each stage of the sleep-wake cycle. The results were compared by Kruskal-Wallis-test. RESULTS FST were counted individually in each sleep phase, being present during quiet sleep (QS) in all tracings. FST bilateral and synchronous and lateralized FST were more frequent during QS (p<0.05). CONCLUSION Lateralized FST were found mostly during quiet sleep. FST asynchronous in healthy full term newborns were normal and depended of FST density. FST unilateral appearance should not necessarily be considered abnormal as well.

No Acute Effects of Cannabidiol on the Sleep-Wake Cycle of Healthy Subjects: A Randomized, Double-Blind, Placebo-Controlled, Crossover Study

Cannabidiol (CBD) is a component of Cannabis sativa that has a broad spectrum of potential therapeutic effects in neuropsychiatric and other disorders. However, few studies have investigated the possible interference of CBD on the sleep-wake cycle. The aim of the present study was to evaluate the effect of a clinically anxiolytic dose of CBD on the sleep-wake cycle of healthy subjects in a crossover, double-blind design. Twenty-seven healthy volunteers that fulfilled the eligibility criteria were selected and allocated to receive either CBD (300 mg) or placebo in the first night in a double-blind randomized design (one volunteer withdrew from the study). In the second night, the same procedure was performed using the substance that had not been administered in the previous occasion. CBD or placebo were administered 30 min before the start of polysomnography recordings that lasted 8 h. Cognitive and subjective measures were performed immediately after polysomnography to assess possible residual effects of CBD. The drug did not induce any significant effect (p > 0.05). Different from anxiolytic and antidepressant drugs such as benzodiazepines and selective serotonin reuptake inhibitors, acute administration of an anxiolytic dose of CBD does not seem to interfere with the sleep cycle of healthy volunteers. The present findings support the proposal that CBD do not alter normal sleep architecture. Future studies should address the effects of CBD on the sleep-wake cycle of patient populations as well as in clinical trials with larger samples and chronic use of different doses of CBD. Such studies are desirable and opportune.

THE EFFECT OF ADAPTED SPORTS IN QUALITY OF LIFE AND BIOPSYCHOSOCIAL PROFILE OF CHILDREN AND ADOLESCENTS WITH CEREBRAL PALSY

ABSTRACT Objective: The participation in sports and recreational activities promotes inclusion and the quality of life (QOL) for people with some type of disability. This study aims to evaluate and describe the effect of adapted sports (AS) on the QOL and biopsychosocial profile of children/adolescents with cerebral palsy (CP). Methods: Forty-seven children/adolescents with CP were evaluated and referred to AS (soccer and swimming). The QOL was evaluated by the Pediatric Outcome Data Collection Instrument (PODCI) and the biopsychosocial profile by the Behavior Checklist for Children/Adolescents (CBCL). These instruments considered the influence of gender, age, race, social income, education and topography of spasticity. Results: Seventeen children/adolescents who practiced AS were re-evaluated after one year. There was significant improvement in the dimensions of transfers and mobility (p=0.009), upper extremity function (p=0.021) and global function (p=0.004) of IARRP. There was significant improvement considering the attention disorder syndrome (p=0.026), and the attention deficit hyperactivity disorders (p=0.008) in the Diagnostic and Statistical Manual of Mental Disorders (DSM)-oriented analysis (CBCL). Children/adolescents with diplegia obtained greater benefit than those with hemiplegia in relation to the comfort and pain (p=0.02) and global dimension (p=0.027) (PODCI). The boys had higher scores in total competence (p=0.048); the extremely poor group obtained higher levels in the breaking rules syndrome (p=0.008). Conclusions: The AS had a positive effect on the QOL and biopsychosocial profile of children/adolescents with CP in this sample, especially considering the global and upper extremity function, capacity for transfers and mobility, and benefits in the problems related to difficulties in attention.
