PURPOSE: To report the clinical and genetic study of two families of Egyptian origin with clinical anophthalmia. To further determine the role of the retina and anterior neural fold homeobox gene (RAX) in anophthalmia and associated cerebral malformations. METHODS: Three patients with clinical anophthalmia and first-degree relatives from two consanguineous families of Egyptian origin underwent full ophthalmologic, general and neurologic examination, and blood tests. Cerebral magnetic resonance imaging (MRI) was performed in the index cases of both families. Genomic DNA was prepared from venous leukocytes, and direct sequencing of all the exons and intron-exon junctions of RAX was performed after PCR amplification. RESULTS: Clinical bilateral anophthalmia was observed in all three patients. General and neurologic examinations were normal; obesity and delay in psychomotor development were observed in the isolated case. Orbital MRI showed a hypoplastic orbit with present but rudimentary extraocular muscles and normal lacrimal glands. Cerebral MRI showed agenesis of the optic nerves, optic tracts, and optic chiasma. In the index case of family A, the absence of the frontal and sphenoidal sinuses was also noted. In the index case of family B, only the sphenoidal sinus was absent, and there was significant cortical atrophy. The three patients carried a novel homozygous c.543+3A>G mutation (IVS2+3A>G) in RAX. Parents were healthy heterozygous carriers. No mutations were detected in orthodenticle homeobox 2 (OTX2), ventral anterior homeobox 1 (VAX1), or sex determining region Y-box 2 (SOX2). CONCLUSIONS: This is the first report of a homozygous splicing RAX mutation associated with autosomal recessive bilateral anophthalmia. To our knowledge, only two isolated cases of anophthalmia, three null and one missense case affecting nuclear localization or the DNA-binding homeodomain, have been found to be caused by compound heterozygote RAX mutations. A novel missense RAX mutation was identified in three patients with bilateral anophthalmia and a distinct systemic and neurologic phenotype. The mutation potentially affects splicing of the last exon and is thought to result in a protein that has an aberrant homeodomain and no paired-tail domain. Functional consequences of this change still need to be characterized.
Failure to thrive in a girl born into a family affected by familial dysalbuminemic hyperthyroxinemia
Resumo:
Autosomal dominant familial dysalbuminemic hyperthyroxinemia (FDH)is characterized by modified human serum albumin (HSA) inducing asubstantially higher affinity for thyroxine (T4). Histidin or prolinsubstitution on residue R218 produces localized conformationalchanges of HSA creating additional room for T4 binding, leadingto 14-20 fold normal total T4 (TT4) levels. Affected individuals areconsidered euthyroid. Our patient is an 18 months-old swiss girl bornto a mother known for the rare R218P mutation in the HSA gene.She presented with severe failure to thrive (height -2.92 SD, weight-3.6 SD), habitual hip dislocation without anatomical anomaly, latefontanelle closing and protruding ears. Psychomotor development isslightly retarded. Thyroid function testing confirmed extremely high TT4(1446.0 nmol/l) levels, which are similar to her brother's values (1534.4nmol/l and 1757.6 nmol/l respectively). Free T4 seems slightly elevated(26 pmol/l), probably due to methodological reasons. TSH (0.92 mU/l),free T3 (4.4 pmol/l) and thyroxin binding globulin (32 mg/l) are withinthe normal range. Her two half-brothers, affected by the samemutation, are now 18.7 (P1) and 16.6 (P2) years old and wereoriginally described by S. Pannain et al. in 2000. Both werecharacterized by growth retardation (-2.1 and -2.2 SD) before the ageof 4 years. P1 has reached a normal adult height (-0.4 SD) and P2has caught up to normal growth (-0.68 SD) with moderate bonematuration delay. Pubertal development and anterior pituitary functionare adequate. Primary growth and developmental retardation in thefirst years of life with adequate catch-up seem to be a distinctcharacteristic in FDH with R218P mutation. Hip dislocation is typicallyseen in other situations associated to thyroid disorders, like Downsyndrome. These findings might be explained by altered early thyroidhormone utilization in children with FDH.
Multisystem Developmental Disorder in Children from 2 to 6 Years Old : A Three Years Follow-Up Study
Resumo:
This research studied children who had been diagnosed with Multisystem Developmental Disorder (MSDD) (NC, 2002) under the Diagnostic Classifications of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC: 0 - 3). They all showed, to a varying degree, difficulties in relating to others, play, affective interaction and severe delay in developing communication skills. Some studies have observed continuity in the diagnosis of autism during the first years of life. The objective of this study is to analyse the development of infants with MSDD whose diagnosis of autism was not confirmed. We also attempted to verify any possible psychomotor developmental differences based on, or related to, the severity and typology (B and C) of the MSDD. To enable us to do this we carried out a 3-year follow-up during which we assessed the infants (n = 15) and their parents. They are 2 - 4 years old. Results showed that type B children did present a greater impairment of psychomotor development in assessment tests. However, we did not observe any correlation between the degree of severity of the initial symptoms and later diagnoses. Conclusion: although our sample is small, we can conclude that there isn’t a clear evolution in the diagnosis, but we have found significant differences in the symptomatology between the type B and C

Les patients atteints de cancers reçoivent différents traitement, tels que la radiothérapie ou la chimiothérapie. Actuellement, environ 60% des enfants survivants du cancer développent des effets secondaires cognitifs, consécutifs aux traitements énoncés précédemment. Compte tenu de la perspective du développement psychomoteur de l’enfant et de l’immaturité du système nerveux central (SNC) chez ces patients, il s’avère particulièrement pertinent d’étudier les effets secondaires que provoquent les traitements anticancéreux sur le développement cognitif de cette population de malades. Des études ont démontrées l’existence de liens étroits entre ces effets secondaires et l’abolition de la neurogénèse provoquée principalement par l’irradiation. Ce projet de maîtrise porte sur les effets du facteur de croissance épidermique, l’EGF (un facteur de croissance impliqué dans la prolifération cellulaire) sur la neurogénèse de la souris. Nous avons également cherché un vecteur de sécrétion efficace pour permettre une diffusion continue d’EGF à long terme (2 à 4 semaines). Notre hypothèse est que l’EGF serait capable de stimuler la neurogénèse et protéger les cellules de l’apoptose dans le cerveau de la souris, suite à une irradiation. Nous avons montré un effet positif de l’EGF sur la formation et la prolifération des neuroblastes Dcx(+) dans la zone sous ventriculaire (ZSV) et non dans l’hippocampe (Hi), suite à l’injection de l’EGF, directement dans le cerveau à l’aide d’une pompe osmotique. Nous avons observé que cette augmentation de la quantité de jeunes neurones est indépendante de la capacité de l’EGF à les protéger de l’apoptose. L’EGF ne protège pas non plus les blastes leucémiques, issus de lignées de cellules humaines, des effets secondaires d’une irradiation. Les cellules souches mésenchymateuses (CSM) modifiées génétiquement et générées pour sécréter l’EGF ne montrent aucun effet sur la stimulation de la neurogénèse quand elles sont directement injectées dans le cerveau. Finalement, nos résultats indiquent que l’EGF pourrait être un bon candidat pour le développement de nouvelles thérapies pour traiter les effets secondaires que provoque une irradiation du cerveau. L’utilisation de pompes pour permettre l’administration d’EGF dans le cerveau devient alors très intéressante pour améliorer la qualité de vie des patients.

Objetivos: analisar o desenvolvimento neuropsicomotor antes e depois de cirurgia cardíaca em crianças através de dois instrumentos: exame neurológico e do teste de Denver II Métodos: foram randomicamente selecionadas os lactentes com indicação de cirurgia cardíaca com utilização de circulação extra-corpórea no período de abril de 2001 a setembro de 2002 Delineamento: coorte prospectivo não controlado Intervenções: Um dia antes da cirurgia eletiva, na alta da unidade de terapia intensiva pediátrica cardíaca e entre 3 a 6 meses após a cirurgia cardíaca os pacientes incluídos no estudo eram submetidos a um exame neurológico padronizado realizado pelo mesmo neurologista pediátrico e ao teste de Denver II aplicado por 2 pediatras de maneira independente, apresentando uma concordância de resultados entre 89-100% . Estatística: O test t student para amostras pareadas para os índices de Denver II . Teste do Qui-quadrado para as categorias do exame neurológico antes e depois de cirurgia. Foi estimado um tamanho amostral de 15 crianças. Resultados: Foram incluídas 20 crianças, com idade média no momento da correção de 6,7 ± 4,2 meses e peso médio 5,3± 2,2 quilogramas. Os defeitos septais ocorreram em 11 casos (55%). O tempo médio de circulação extra-corpórea era 67± 23,6 minutos, com o uso de ultrafiltração modificada. Quinze crianças tinham atraso no desenvolvimento de neuropsicomotor no momento da cirurgia, mas em seis foi observado normalização depois de 3 a 6 meses de seguimento (p=0,11). Quando os índices de Denver II, dentro de cada domínio, foram analisados (índices motor grosseiro, motor fino, linguagem, total e pessoal-social), observou-se um aumento em todos os domínios após a cirurgia, exceto o último (p < 0.05). O percentual médio de melhora nos índices oscilou entre 17 a 23%. Um tamanho de efeito grande foi calculado para linguagem e moderado nas habilidades de motoras. Conclusão: Apesar destas crianças estarem em risco de novos achados neurológicos, os resultados sugerem uma melhora precoce nos índices de desenvolvimento neuropsicomotor após cirurgia cardíaca com extra-corpórea.

Abstract: When and how the dentist intervenes have repercussions on children's physical and emotional patterns. The objective of the present study was to conduct a longitudinal behavioral analysis during dental care of babies aged 0 to 3 years. A total of 216 patients seen at the Baby Clinic of the School of Dentistry at Araçatuba, São Paulo State University (UNESP), were selected. The selection criterion was attendance at ten dental care sessions at bimonthly intervals for routine procedures such as clinical examination and oral hygiene. There was a predominance of cooperative behavior compared to uncooperative behavior when each visit was analyzed separately. The behavior of the patients must have been directly influenced by their psychomotor development. Constant attendance and exposure of the baby to non-stressful dental stimuli are factors that favor a cooperative behavior.

Objective: To review scientific literature in order to check how infant development surveillance is being carried out in Brazil. Data sources: Search on databases (PubMed, Medline, SciELO and CAPES Database Thesis) for studies on medical practices related to surveillance and monitoring of child development in Brazil from 2000 to 2011. The terms used for research were: child development surveillance, early intervention, developmental screening, and developmental screening tests. There were ten texts on the subject under study. Original articles, reviews, and thesis were analyzed, as well as the reference lists of publications on the topic. Data synthesis: Studies on monitoring of child development in Brazil showed major failures from pediatrician formation to clinical practice. Conclusions: It is urgent to offer continued medical education to pediatricians in order to update their knowledge about child development monitoring, especially due to the increasing numbers of preterm infants.

Dance activities were administered to a group of deaf adolescents via visual and auditory stimuli in order to improve their perceptions of monotonic rhythmic structures. Status of psychomotor development was also assessed before and after participation in the program. Twenty deaf adolescents (ages between 12 and 13 years) were divided into two groups, experimental (EG) and control (CG). Before and after participating in the program for 26 weeks, participants were evaluated in rhythmical tasks adapted from the classical test of M. Stambak. The tasks included the perception of drum beats, actually viewed hit movements, or heard via a sound amplifier. Psychomotor tests were administered only to the EG. The period of practice with dance activities changed the individuals' performance in the monotonic rhythmic test. Also, the success rate improved in both, visual and auditory input tasks. Individuals in the CG showed no changes in performance. For the EG, in the post-test, the status of psychomotor development was six months below the target age of the tests (i.e., 11 years). Findings suggested that dance activities can change deaf individuals' auditory perception of rhythmic structures. Participation in such a program can also positively affect psychomotor development. © FTCD/FIP-MOC.

O objetivo foi identificar os determinantes da saúde ruim em populações ribeirinhas menores de dois anos, residentes no Pará, Brasil. Foram avaliadas 202 crianças, considerando-se saúde ruim como variável desfecho, sendo composta pela combinação do estado nutricional, desenvolvimento físico-motor e intercorrências no último mês. Utilizou-se modelo multinível de análise hierárquica, considerando-se como preditoras da saúde ruim variáveis com p < 0,05 após ajuste. A razão de chance bruta apontou que o estado de saúde ruim é maior para as crianças de famílias que têm casa própria, são de maior idade e têm probabilidade de aleitamento materno exclusivo aos dois, três, quatro e cinco meses. Após ajuste, observa-se que crianças provenientes de famílias com casa própria têm 2,76 vezes mais chance de ter saúde ruim; esta também aumenta com a idade, chegando a ser 5,04 vezes maior entre as crianças de 18 a 23 meses, comparativamente às menores de 7 meses. Ter casa própria e mais idade representam, nessas comunidades, mais tempo de exposição ao risco de saúde ruim.

No presente estudo foram analisados possíveis fatores bio-sócio-ambientais interferentes na exposição ao mercúrio em crianças ribeirinhas. Participaram 103 crianças das regiões do rio Tapajós, rio Acará e ilha do Marajó. O tipo de estudo foi seccional analítico. Foram colhidas amostras de cabelo para análise dos teores de Hgtotal, de sangue (análise de hemoglobina e hematócrito) e fezes. Foram utilizados índices antropométricos na análise do crescimento das crianças. Na avaliação do desenvolvimento neuropsicomotor foi aplicado o teste de triagem Denver II modificado. A maior média dos teores de Hgtotal em amostras de cabelo das crianças foi na região do Tapajós (5,58 μg/g) e 0,65 μg/g nas demais localidades. A prevalência de Hgtotal >10 μg/g foi 25% e 7,5% em São Luiz do Tapajós e Barreira. O consumo diário de peixes pelas famílias das crianças quando relacionado com teores de Hgtotal p(valor) foi < 0,05. A prevalência do tempo de amamentação das crianças nos grupos com menos de 12 meses e maior de 6 meses para as localidades do rio Tapajós, quando relacionadas com teores de Hgtotal no cabelo das crianças apresentou p(valor) <0,05. A prevalência de anemia nas crianças da região Tapajós era de 46,7% e quando relacionada com teores de Hgtotal p(valor) <0,0001.Os exames coproscópicos indicaram que 68,3% eram poliparasitadas, quando relacionadas com Hgtotal p(valor) <0,05. O perfil do crescimento observado através dos indicadores do estado nutricional era 82,6% com peso adequado para idade e 14,5% com peso muito baixo e baixo. O desempenho neuropsicomotor examinado pelo teste de triagem Denver II modificado apresentou cinco crianças como suspeitas de atraso no desenvolvimento. Concluiu-se que localidades no entorno de atividades garimpeira as crianças ribeirinhas são expostas ao risco de contaminação mercurial. Fatores bio-sócio-ambientais interferentes na exposição ao mercúrio tais como consumo diário de peixes, tempo de amamentação, anemia, enteroparasitoses apresentaram relações estatísticas significativas com o Hgtotal no cabelo das crianças.
