Studies investigating the possible benefits of transcranial direct current stimulation on left dorsolateral prefrontal cortex in children and adolescents with attention-deficit hyperactivity disorder (ADHD) have not been performed. This study assesses the effect of transcranial direct current stimulation in children and adolescents with ADHD on neuropsychological tests of visual attention, visual and verbal working memory, and inhibitory control. An auto-matched clinical trial was performed involving transcranial direct current stimulation in children and adolescents with ADHD, using SNAP-IV and subtests Vocabulary and Cubes of the Wechsler Intelligence Scale for Children III (WISC-III). Subjects were assessed before and after transcranial direct current stimulation sessions with the Digit Span subtest of the WISC-III, inhibitory control subtest of the NEPSY-II, Corsi cubes, and the Visual Attention Test (TAVIS-3). There were 9 individuals with ADHD according to Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) criteria. There was statistically significant difference in some aspects of TAVIS-3 tests and the inhibitory control subtest of NEPSY-II. Transcranial direct current stimulation can be related to a more efficient processing speed, improved detection of stimuli, and improved ability to switch between an ongoing activity and a new one.
Objective: To describe the 2-year neurodevelopmental outcome in children with cerebral palsy associated with congenital Zika (CZ) and explore variables associated with a more severe presentation. Methods: Data on 69 children with cerebral palsy associated with CZ, followed in a neurorehabilitation hospital, who consecutively attended the neurodevelopmental assessment at 2 years of age, were collected. Bayley III Scales of Infant and Toddler Development, Hammersmith Infant Neurological Examination, and Gross Motor Function Classification System were used for the outcome evaluation. Descriptive and inferential statistical analysis were performed. Results: The median age at follow-up was of 24.0 (23-32) months. Only 3 (4.3%) children were not microcephalic. The majority presented with bilateral (94.2%), spastic (100.0%), Gross Motor Function Classification System grade IV or V (92.8%) cerebral palsy, epilepsy (73.1%), extremely low performances on cognitive (94.2%), language (95.7%), and motor (95.7%) Bayley-III Scales of Infant and Toddler Development Test scores. The median Hammersmith Infant Neurological Examination score was of 21.0 (range 9-75). There was a correlation between birth head circumference with the cognitive ( r = 0.3, P < .01), language ( r = 0.3, P < .01), and motor ( r = 0.3, P < .01) Bayley-III Scales of Infant and Toddler Development Test scores, as well as with the Hammersmith Infant Neurological Examination score ( r = 0.2, P < .03). An association was observed between an inferior median Hammersmith Infant Neurological Examination score with congenital microcephaly ( P = .04), arthrogryposis ( P = .02), and epilepsy in the first year ( P < .01). Conclusion: Cerebral palsy related to CZ presents with a severe global impairment at a 2-year follow-up. Birth head circumference, arthrogryposis, and early epilepsy are associated with a worse outcome and may be considered as prognostic markers. These findings are important for the neurorehabilitation planning, parents’ guiding, and future prognostic studies.
A mass immunization campaign with a Urabe-containing measles-mumps-rubella vaccine was carried out in 1997 in the city of Salvador, northeastern Brazil, with a target population of children aged 1-11 years. There was an outbreak of aseptic meningitis following the mass campaign. Cases of aseptic meningitis were ascertained through data collected from the records of children admitted to the local referral hospital for infectious diseases between March and October of 1997, using previously defined eligibility criteria. Vaccination histories were obtained through home visits or telephone calls. Eighty-seven cases fulfilled the study criteria. Of those, 58 cases were diagnosed after the vaccination campaign. An elevated risk of aseptic meningitis was observed 3 weeks after Brazil's national vaccination day compared with the risk in the prevaccination period (relative risk = 14.3; 95% confidence interval: 7.9, 25.7). This result was confirmed by a case series analysis (relative risk = 30.4; 95% confidence interval: 11.5, 80.8). The estimated risk of aseptic meningitis was 1 in 14,000 doses. This study confirms a link between measles-mumps-rubella vaccination and aseptic meningitis. The authors discuss the implications of this for the organization and planning of mass immunization campaigns.
Transcranial direct current stimulation is a noninvasive brain stimulation technique that has been studied for the treatment of neuropsychiatric disorders in adults, with minimal side effects. The objective of this study is to report the feasibility, tolerability, and the short-term adverse effects of transcranial direct current stimulation in children from 5 to 12 years of age. It is a naturalistic study of 14 children who underwent 10 sessions of transcranial direct current stimulation as an alternative, off-label, and open-label treatment for various languages disorders. Frequency, intensity, adverse effects, and perception of improvement reported by parents were collected. The main side effects detected were tingling (28.6%) and itching (28.6%), acute mood changes (42.9%), and irritability (35.7%). Transcranial direct current stimulation is a feasible and tolerable technique in children, although studies regarding plastic and cognitive changes in children are needed to confirm its safety. In conclusion, this is a naturalistic report in which we considered transcranial direct current stimulation as feasible in children.
Muscle over-activity is one of the cardinal features of spasticity and it is a common disability of stroke patients. In this group, spasticity is responsible for several limitations that interfere in their daily activities and quality of life. To treat spasticity, neurologists usually prescribe drugs as baclofen, tizanidine or benzodiazepines or even use definitive treatment as phenol or surgery. Authors suggest the use of botulinum toxin type A (BTX-A) for spasticity in the upper limbs after stroke, but there are few papers with adequate methodology supporting this idea. In this article we summarize the data of previous double-blind, randomised clinical trials to asses, with a meta-analysis, if BTX-A is an adequate treatment for spasticity due to stroke. The results show a statistical superiority of BTX-A ov%r placebo on reducing muscle tone by the Modified Ashworth Scale (WMD= 0.95 [0.74 to 1.17]) in patients with post-stroke upper limb spasticity.
Current treatments for infected dogs with leishmaniasis do not always provide long-term control of the disease and clinical relapses are common. In this study, the usefulness of long-term allopurinol administration in the maintenance of clinical remission in canine leishmaniasis was evaluated. Fifteen dogs with natural leishmania infection were subjected to an initial treatment based on the simultaneous administration of meglumine antimoniate (100 mg/kg/day) and allopurinol (30 mg/kg/day). Once clinical remission was achieved, a maintenance treatment with allopurinol (20 mg/kg/day) administered for one week a month was instituted. Results were compared with those of a retrospective control group comprising 15 infected dogs which only followed the induction treatment. Relapses occurred in 86 per cent of control dogs within 14 months of discontinuing treatment. In contrast, those dogs on intermittent oral allopurinol administration were successfully maintained in clinical remission for a follow-up period of 10 to 44 months. In this latter group, specific antibody titres decreased or were unchanged, no side effects directly attributable to allopurinol were seen and treatment was well accepted by the owners. It is concluded that long-term intermittent administration of allopurinol is an effective way of maintaining clinical remission in dogs with leishmaniasis.
