A música associada às necessidades terapêuticas de pacientes com deficiência

The use of music and/or its elements (instruments, sound, rhythm, melody and harmony) in environments with people attended by public health centers, aims at promoting communication, facilitating the expression and the relationship in the first contact, hence favoring organization of standards and other relevant therapeutic objectives to assist physical, mental, social and cognitive needs of people, thus promoting the process of environmental adaptation, behavioral conditioning and social inclusion. The purpose of this project is to use music and its sound elements, as well as recreational activities, developed in stages called: socialization session, art workshop and complementary activities, with patients assisted at CAOE (Disabled People Dental Care Center) and their relatives. The objective is to provide them psychological wellbeing, inclusion to physical space, relaxation, stimulation of rhythmic and sonorous perceptions, memorization, emotions externalization, help and encouragement for the development of motor coordination during their daily activities of daily. Recreational activities, handling and contacting with musical instruments, broadcasting and producing sounds, stimulate cognitive capacity, interactivity and entertainment activities can greatly contribute to improve the behavioral reaction and adaptation of these patients, during their dental treatment.

Hemofilia A em cão: relato de caso

Hemophilia A is an X-linked inherited disorder characterized by a Factor VIII (FVIII) deficiency, being therefore transmitted by female dogs to their offspring. Since it is a secondary hemostatic defect, the main clinical signs are hematomas and deep hemorrhage in body cavities, muscles and joints. A four-month-old male Boxer was presented to the Veterinary Hospital at the School of Veterinary Medicine and Animal Science in Botucatu with excessive bleeding due to an incision made three days prior by another veterinarian to drain a local hematoma. Laboratory results showed platelet count within the reference range, as well as prolonged whole blood clotting and activated partial thromboplastin times. FVIII activity was 0,96%, which characterizes the most severe degree of hemophilia A.

Estudo morfofuncional dos rins de cães da raça Golden Retriever afetados pela distrofia muscular (GRMD)

A Distrofia Muscular de Duchenne (DMD) é uma miopatia severa de caráter recessivo ligada ao cromossomo X e o modelo animal de estudo mais relevante é o Golden Retriever Muscular Dystrophy (GRMD). Além das severas alterações que ocorrem na musculatura estriada, muitos estudos mostram que outras estruturas, inclusive viscerais, podem se mostrar alteradas nesta patologia. Desta forma, este trabalho objetivou análisar e comparar possíveis alterações estruturais e funcionais do rim em cães GRMD. Neste modelo de estudo, foi possível observar a presença das faces convexa e côncava, do hilo renal e dos pólos craniais e caudais dos rins. O órgão mostrou-se envolto por uma cápsula fibrosa. Em um corte sagital do órgão, notou-se a presença das regiões cortical e medular e da pelve renal. Na análise microscópica foi possível identificar a zona medular e cortical com suas estruturas: os corpúsculos renais formados pelo glomérulo e pela cápsula de Bowman, os túbulos contorcidos proximais e distais, os ductos coletores, vasos sanguíneos e os segmentos das Alças de Henle. As dosagens séricas de creatinina e uréia encontram-se dentro dos limites de normalidade. Desta forma, de acordo com os nossos resultados, podemos concluir que os animais afetados estudados, não apresentaram alterações estruturais ou funcionais dos rins, o que nos permitir sugerir que apesar da ingestão hídrica comprometida, a estrutura renal, mantem- se preservada nos animais GRMD.

Estudo morfológico do Sistema Nervoso Central de cães com Distrofia Muscular do Golden Retriever (GRMD)

Distrofia muscular de Duchenne é uma desordem neuromuscular causada pela mutação ou deleção do gene da distrofina, a qual é ligada ao cromossomo X. Estudos recentes têm demonstrado o importante papel da distrofina no SNC, sendo sua deficiência relacionada com uma variedade de anormalidades na função do SNC, como comportamento e disfunção cognitiva. Os modelos animais mais adequados para esses estudos são os que apresentam o quadro clinico mais semelhante ao da DMD encontrada em humanos, como cães Golden Retriever com distrofia muscular (GRMD). Por não haver ainda estudos a respeito do SNC de animais GRMD, o objetivo deste trabalho foi analisar a morfologia do encéfalo dos GRMD e o de animais não distróficos, através de análise macroscópica, utilizando métodos de medição e registro fotográfico, e análise microscópica, utilizando a técnica de coloração de violeta cresil modificada. Entretanto, usando a metodologia proposta, não foi possível verificar diferenças significativas no encéfalo quando comparados os animais distróficos e os não distróficos, o que está em concordância com a literatura para a DMD usando os mesmos parâmetros. Em tempo, existe uma variação individual na morfologia do encéfalo do cão, independente de serem animais do grupo de distróficos ou controles. Outras técnicas devem ser aplicadas a fim de elucidar as consequências da ausência total ou parcial da distrofina no SNC

Síndrome de Lennox-Gastaut: descripción clínica y correlación de la frecuencia de crisis con el coeficiente intelectual

Trata de describir las características clínicas del síndrome de Lennox- Gastaut en los niños del Hospital Vicente Corral Moscoso y ADINEA (Asociación para el Desarrollo Integral del Niño Excepcional del Azuay) de la ciudad de Cuenca-Ecuador; y determinar la relación existente entre la frecuencia de crisis epilépticas de un niño con diagnóstico de síndrome de Lennox-Gastaut y su grado de retardo mental. Son diagnosticados treinta pacientes de los cuáles 17 fueron del sexo masculino 56,7y 13 pacientes sexo femenino 43,3. La mayoría inician sus crisis antes del año de edad, se relacionan con un mayor retardo mental y a su vez con mayor frecuencia de crisis. La etiología más frecuente es la hipoxis al nacimiento, que está relacionada con la precaria atención de salud del país, en la mayoría de los casos no es posible determinar su etiología, pero existe una importante predisposición familiar. Indican que se debería ampliar los métodos de diagnóstico a fin de precisar mejor la etiología

Prevalencia del bocio e hipotiroidismo en la parroquía Cojitambo

Se estima que mil millones de personas se hallan expuestas al riesgo de padecer bocio por deficiencia de yodo y la mayoria de ellas viven el las regiones tropicales del tercer mundo ya hace treinta años se estimo que más de docientos millones de personas estuvieron afectadas del bocio y existen muy poca razón para creer en ese número sea diferente. En nuestro país al igual que en otras naciones del tercer mundo, el indice de afectación por bocio endémico todavía tiene connotación médica y social importante, como lo demuestra el INIMS, en sus estudios realizados en el año 1983 en las 10 provincias de la sierra con una prevalencia del 36.5% de bocio endémico es decir muy similar a la encontrada en el año 1960 a pesar del adelanto científico y técnologico de la sociedad la misma que es un problema real de la salud pública que no ha sido resuelto. El bocio endémico es mucho más que un simple problema estético ya que va asociado epidemiológicamente al cretinismo endémico con la sordumudez y el retardo mental así como tambien la elevación de la tasa de mortalida perinatal, bajo peso al nacer y retardo en el desarrollo.

The reduced expression of the HADH2 protein causes X-linked mental retardation, choreoathetosis, and abnormal behavior

Recently, we defined a new syndromic form of X-linked mental retardation in a 4-generation family with a unique clinical phenotype characterized by mild mental retardation, choreoathetosis, and abnormal behavior (MRXS10). Linkage analysis in this family revealed a candidate region of 13.4 Mb between markers DXS1201 and DXS991 on Xp11; therefore, mutation analysis was performed by direct sequencing in most of the 135 annotated genes located in the region. The gene (HADH2) encoding L-3-hydroxyacyl-CoA dehydrogenase II displayed a sequence alteration (c.574 C-->A; p.R192R) in all patients and carrier females that was absent in unaffected male family members and could not be found in 2,500 control X chromosomes, including in those of 500 healthy males. The silent C-->A substitution is located in exon 5 and was shown by western blot to reduce the amount of HADH2 protein by 60%-70% in the patient. Quantitative in vivo and in vitro expression studies revealed a ratio of splicing transcript amounts different from those normally seen in controls. Apparently, the reduced expression of the wild-type fragment, which results in the decreased protein expression, rather than the increased amount of aberrant splicing fragments of the HADH2 gene, is pathogenic. Our data therefore strongly suggest that reduced expression of the HADH2 protein causes MRXS10, a phenotype different from that caused by 2-methyl-3-hydroxybutyryl-CoA dehydrogenase deficiency, which is a neurodegenerative disorder caused by missense mutations in this multifunctional protein.

Mandibulofacial Syndrome With Growth and Mental Retardation, Microcephaly, Ear Anomalies With Skin Tags, and Cleft Palate in a Mother and Her Son: Autosomal Dominant or X-Linked Syndrome?

We report on a Brazilian mother and her son affected with mandibulofacial dysostosis, growth and mental retardation, microcephaly, first branchial arch anomalies, and cleft palate. To date only three males and one female, all sporadic cases, with a similar condition have been reported. This article describes the first familial case with this rare condition indicating autosomal dominant or X-linked inheritance. (C) 2009 Wiley-Liss, Inc.

From nature versus nurture, via nature and nurture, to gene x environment interaction in mental disorders

It is now generally accepted that complex mental disorders are the results of interplay between genetic and environmental factors. This holds out the prospect that by studying G x E interplay we can explain individual variation in vulnerability and resilience to environmental hazards in the development of mental disorders. Furthermore studying G x E findings may give insights in neurobiological mechanisms of psychiatric disorder and so improve individualized treatment and potentially prevention. In this paper, we provide an overview of the state of field with regard to G x E in mental disorders. Strategies for G x E research are introduced. G x E findings from selected mental disorders with onset in childhood or adolescence are reviewed [such as depressive disorders, attention-deficit/hyperactivity disorder (ADHD), obesity, schizophrenia and substance use disorders]. Early seminal studies provided evidence for G x E in the pathogenesis of depression implicating 5-HTTLPR, and conduct problems implicating MAOA. Since then G x E effects have been seen across a wide range of mental disorders (e.g., ADHD, anxiety, schizophrenia, substance abuse disorder) implicating a wide range of measured genes and measured environments (e.g., pre-, peri- and postnatal influences of both a physical and a social nature). To date few of these G x E effects have been sufficiently replicated. Indeed meta-analyses have raised doubts about the robustness of even the most well studied findings. In future we need larger, sufficiently powered studies that include a detailed and sophisticated characterization of both phenotype and the environmental risk.

Fragile X mental retardation protein is translated near synapses in response to neurotransmitter activation

Local translation of proteins in distal dendrites is thought to support synaptic structural plasticity. We have previously shown that metabotropic glutamate receptor (mGluR1) stimulation initiates a phosphorylation cascade, triggering rapid association of some mRNAs with translation machinery near synapses, and leading to protein synthesis. To determine the identity of these mRNAs, a cDNA library produced from distal nerve processes was used to screen synaptic polyribosome-associated mRNA. We identified mRNA for the fragile X mental retardation protein (FMRP) in these processes by use of synaptic subcellular fractions, termed synaptoneurosomes. We found that this mRNA associates with translational complexes in synaptoneurosomes within 1–2 min after mGluR1 stimulation of this preparation, and we observed increased expression of FMRP after mGluR1 stimulation. In addition, we found that FMRP is associated with polyribosomal complexes in these fractions. In vivo, we observed FMRP immunoreactivity in spines, dendrites, and somata of the developing rat brain, but not in nuclei or axons. We suggest that rapid production of FMRP near synapses in response to activation may be important for normal maturation of synaptic connections.

A highly conserved protein family interacting with the fragile X mental retardation protein (FMRP) and displaying selective interactions with FMRP-related proteins FXR1P and FXR2P

The absence of the fragile X mental retardation protein (FMRP), encoded by the FMR1 gene, is responsible for pathologic manifestations in the Fragile X Syndrome, the most frequent cause of inherited mental retardation. FMRP is an RNA-binding protein associated with polysomes as part of a messenger ribonucleoprotein (mRNP) complex. Although its function is poorly understood, various observations suggest a role in local protein translation at neuronal dendrites and in dendritic spine maturation. We present here the identification of CYFIP1/2 (Cytoplasmic FMRP Interacting Proteins) as FMRP interactors. CYFIP1/2 share 88% amino acid sequence identity and represent the two members in humans of a highly conserved protein family. Remarkably, whereas CYFIP2 also interacts with the FMRP-related proteins FXR1P/2P, CYFIP1 interacts exclusively with FMRP. FMRP–CYFIP interaction involves the domain of FMRP also mediating homo- and heteromerization, thus suggesting a competition between interaction among the FXR proteins and interaction with CYFIP. CYFIP1/2 are proteins of unknown function, but CYFIP1 has recently been shown to interact with the small GTPase Rac1, which is implicated in development and maintenance of neuronal structures. Consistent with FMRP and Rac1 localization in dendritic fine structures, CYFIP1/2 are present in synaptosomal extracts.

Mental health issues and resources in rural and regional communities : an exploration of perceptions of service providers

Objective: To identify service providers’ and community organisations’ perceptions of the resources available to support people with mental illness and the unmet needs of this client group in rural Queensland. Design: An exploratory study was undertaken involving focus group interviews across the study sites. Setting: Five regional towns in rural Queensland. Participants: Ten to 14 members were recruited for each of the five focus groups. The groups represented a diverse mix of participants including health and community service providers and representatives from community organisations. Results: Participants identified gaps in services in relation to health, employment and education, housing and accommodation, transport and social inclusion and health promotion. Inter-service communication and inappropriate funding models were themes affecting service delivery. Conclusions: Specific service issues of housing and transport were identified to be particularly problematic for people with mental illness across all towns. Intersectoral communication and funding models require further research.
