Motor development of children with attention deficit hyperactivity disorder

Objective: To compare both global and specific domains of motor development of children with attention deficit hyperactivity disorder (ADHD) with that of typically developing children. Methods: Two hundred children (50 children with clinical diagnoses of ADHD, according to the DSM-IV-TR and 150 typically developing controls), aged 5 to 10 years, participated in this crosssectional study. The Motor Development Scale was used to assess fine and global motricity, balance, body schema, and spatial and temporal organization. Results: Between-group testing revealed statistically significant differences between the ADHD and control groups for all domains. The results also revealed a deficit of nearly two years in the motor development of children with ADHD compared with the normative sample. Conclusion: The current study shows that ADHD is associated with a delay in motor development when compared to typically developing children. The results also suggested difficulties in certain motor areas for those with ADHD. These results may point to plausible mechanisms underlying the relationship between ADHD and motor difficulties

Traditional allergen immunotherapy presents several clinical drawbacks that can be reduced by using nanoparticles-basedallergen-delivery systems, modulating the immune response towards a protective one. In this context, the goal of this work was to assess the potential of poly(anhydride) nanoparticles (NP) for cashew nut oral immunization. Cashew nut allergens-loaded nanoparticles (CNE-NP) were prepared by solvent displacement method. After nanoparticles characterization, oral immunomodulation ability was evaluated in BALB/c mice. Our results demonstrated that CNE-NP induced a higher Th1/Th2 ratio in comparison with animals immunized with free cashew nut proteins. Indeed, a decrease in splenic Th2 cytokines (IL-4, IL-5, and IL-13), and an enhancement of pro-Th1 (IL-12 and IFN-γ) and regulatory (IL-10) cytokines was observed. Furthermore, mice orally immunized with CNE-NP presented an increased expansion of CD4+ T regulatory cells, such as CD4+Foxp3+ and CD4+LAP+, in the mesenteric lymph nodes. In conclusion, oral immunization with a single dose of poly(anhydride) nanoparticles loaded with cashew nut proteins leaded to a pro-Th1 and Treg immune response. Furthermore, their immunomodulatory properties could be introduced as a new approach for management of cashew nut allergy

Prevalence of spinocerebellar ataxia 36 in a US population.

ObjectiveTo assess the prevalence and clinical features of individuals affected by spinocerebellar ataxia 36 (SCA36) at a large tertiary referral center in the United States.MethodsA total of 577 patients with undiagnosed sporadic or familial cerebellar ataxia comprehensively evaluated at a tertiary referral ataxia center were molecularly evaluated for SCA36. Repeat primed PCR and fragment analysis were used to screen for the presence of a repeat expansion in the NOP56 gene.ResultsFragment analysis of triplet repeat primed PCR products identified a GGCCTG hexanucleotide repeat expansion in intron 1 of NOP56 in 4 index cases. These 4 SCA36-positive families comprised 2 distinct ethnic groups: white (European) (2) and Asian (Japanese [1] and Vietnamese [1]). Individuals affected by SCA36 exhibited typical clinical features with gait ataxia and age at onset ranging between 35 and 50 years. Patients also suffered from ataxic or spastic limbs, altered reflexes, abnormal ocular movement, and cognitive impairment.ConclusionsIn a US population, SCA36 was observed to be a rare disorder, accounting for 0.7% (4/577 index cases) of disease in a large undiagnosed ataxia cohort

A diagnostic ceiling for exome sequencing in cerebellar ataxia and related neurological disorders

Genetic ataxias are associated with mutations in hundreds of genes with high phenotypic overlap complicating the clinical diagnosis. Whole-exome sequencing (WES) has increased the overall diagnostic rate considerably. However, the upper limit of this method remains ill-defined, hindering efforts to address the remaining diagnostic gap. To further assess the role of rare coding variation in ataxic disorders, we reanalyzed our previously published exome cohort of 76 predominantly adult and sporadic-onset patients, expanded the total number of cases to 260, and introduced analyses for copy number variation and repeat expansion in a representative subset. For new cases (n = 184), our resulting clinically relevant detection rate remained stable at 47% with 24% classified as pathogenic. Reanalysis of the previously sequenced 76 patients modestly improved the pathogenic rate by 7%. For the combined cohort (n = 260), the total observed clinical detection rate was 52% with 25% classified as pathogenic. Published studies of similar neurological phenotypes report comparable rates. This consistency across multiple cohorts suggests that, despite continued technical and analytical advancements, an approximately 50% diagnostic rate marks a relative ceiling for current WES-based methods and a more comprehensive genome-wide assessment is needed to identify the missing causative genetic etiologies for cerebellar ataxia and related neurodegenerative diseases

Fonoaudiologia X ronco/apneia do sono Speech therapy and snore and sleep apnea

TEMA: sendo o sono necessário para termos energia, o ronco e a apneia do sono tornam-se obstáculos que acarretam problemas de saúde, como também problemas sociais, conjugais, escolares, entre outros. OBJETIVO: contribuir para um maior conhecimento do profissional fonoaudiólogo sobre as causas, consequências, diagnóstico e formas de tratamento da apneia obstrutiva do sono (AOS), a fim de favorecer a definição da conduta por este profissional, seja ela, encaminhar para um diagnóstico, tratar (por meio de fonoterapia) essa patologia ou indicar o tratamento médico, seja ele, cirúrgico ou conservador. CONCLUSÃO: as possíveis alterações fonoaudiológicas encontradas nestes pacientes são: língua alargada apresentando hipotonia, palato mole com volume aumentado, dificuldade na alimentação devido ao aporte insuficiente de ar e ao bruxismo, possivelmente causado pela tensão e ansiedade decorrentes das noites mal dormidas. Outras alterações podem ser encontradas decorrentes do tratamento cirúrgico empregado em alguns casos, como a disfagia ou até mesmo alterações na fala e na ressonância da fala decorrente de uma uvulopalatoplastia. O enfoque do tratamento fonoaudiológico é a mioterapia dos músculos envolvidos, priorizando a musculatura palatal. Percebe-se que o fonoaudiólogo pode contribuir para amenizar os sintomas encontrados nestas patologias, proporcionando uma qualidade de vida melhor aos seus portadores.<br>BACKGROUND: sleeping is necessary to provide us with energy. However, snoring and sleep apnea become obstacles that cause not only health problems, but also social, marital and educational issues. PURPOSE: contribute with a better understanding of the causes to the speech therapist, as well as the diagnosis and forms of treatment for Obstructive Sleep Apnea (OSA). Facilitate the definition of conduct by the therapist, be it a guide for a diagnosis, a treatment for that disease (through speech therapy) or the indication of medical treatment (surgical or conservative). CONCLUSION: some possible speech pathologies found in these patients are: enlarged tongue presenting hypotonia, soft palate with increased volume, difficulty in feeding due to insufficient intake of air and bruxism, possibly caused by tension and anxiety of bad night's sleep. Other changes can be found due to surgical treatment used in some cases, such as dysphagia or even alterations in speech and resonance of speech caused by an uvulopalatoplasty. The focus of speech therapy is the myotherapy of the involved muscles, prioritizing the palatal muscles. It is perceived that the speech therapists can help to ease the symptoms found in these diseases, providing a better life quality for their patients
