Adesão ao tratamento do hipotireoidismo congênito segundo relato de cuidadores
(2010-04) OLIVEIRA, Fabiana Pereira Sabino de; FERREIRA, Eleonora Arnaud Pereira
This study aims at identifying variables which interfere on the entry into the treatment according to reports of caregivers of children suffering from Congenital Hypothyroidism seen at the Center of Reference in Pará State. Fifty main caregivers, with different degrees of kinship to the children and ranging from 17 to 55 years old, took part in this study. The variables related to the treatment entry were identified by means of interviews with the caregivers following structured pilot instructions. Results showed that most of the caregivers are not aware of the characteristics of the disease, its etiology, diagnosis, treatment and prognostic, regardless the age, school degree, kinship and amount of time the child is on the Program, which makes the treatment entry more difficult. In most children, the Newborn Screening Test was not done in the right time, fact that brought damage to the treatment.

Adesão ao tratamento por cuidadores de crianças com hipotireoidismo congênito

Chronic diseases which require attention and continuous evaluations and have called for attention ofhealth professionals, specially those who devote themselves to the area ofPediatric Psychology, who devote themselves to the study of child development, as well as to the relationship between health and sickness and the interferences in the life quality of children and their relatives. This study aims accomplishing a descriptive study to identify variables making easier or more difficult, the adherence to the treatment of caregivers of children with Congenital Hypothyroidism, attended by the Center of Reference in Pará State. Fifty main caregivers ranging between 17 to 55 years of age. Forty mothers, four grandmothers, four fathers and two aunts took part in this study. Variables related to the adherence were identified by means of structured interviews. Program characteristics were analyzed through structured interviews carried out by the team professionals. The analyses of caregivers reports showed that some of the demands to the treatment adherence are not being supplied. Informations about the illness characteristics, etiology, diagnostics, treatment and prognostics are not part of the repertory of most caregivers, independently of age, school degree, degree of relationship with reiatives and time of participation in the Neonatal Selection Programo Significant differences were found regarding the adequate time for the exam accomplishment, which showed the delay of the treatment start. The difficulties described by the professionals as to the adherence to the treatment by the caregivers were attributed not only to the problems showed by the Program structure itselfbut also by the lack of interest to it. The study brings relevant implications to the implantation of more effective and efficacious prevention programs to attend the needs of caregivers and promote the adequate child development.

Avaliação eletrorretinográfica de ratos wistar jovens submetidos à tireoidectomia bilateral
(Universidade Federal do Pará, 2012-10-31) RODRIGUES, Keuri Eleutério; ROCHA, Fernando Allan de Farias; http://lattes.cnpq.br/3882851981484245
The thyroid synthesizes thyroxine (T4) and 3,5,3 '-triiodothyronine (T3), both hormones have a crucial role in the development of the central nervous system, including the retina and visual system. The decrease in blood levels of T3 and T4 causes a syndrome called hypothyroidism, which may lead to visual impairment. The visual deficits generated by hypothyroidism are directly related to the development period of the individual. It has been demonstrated in murine models that congenital hypothyroidism decreases the retinal thickness, the number of cells and interferes with the differentiation of M cones. Here, we investigated the possible functional changes in juvenile rat’s retina after bilateral thyroidectomy using noninvasive electrophysiological responses. Therefore, we divided the rats into three groups (control, sham and thyreoidectomized) each containing n≥8 animals. The surgeries were performed 30 days post-natal and the full-field electroretinogram (ERG) were performed 10, 15, 20, 25 and 30 days after surgery, using standard protocols for assessing the scotopic response maximum, photopic response (with and without the use of light filters) and response to flicker (12, 15, 18 and 30 Hz). The parameters analyzed were implicit time and amplitude of a- and b-waves of ERG. We also perform monitoring of clinical parameters of animals in order to identify characteristics that indicate a hypothyroidism, as well as the dosage of thyroid hormones. The results showed that there was a decrease in the a- and b-waves amplitudes in thyroidectomy animals (10, 15, 20, 25 and 30 days after surgery), compared to control and sham animals at all the stimulation protocols used in ERG. The results of the evaluation of the implicit time for both waves showed none statistical difference when comparing to control and sham groups. Also we observed a reduction in size and weight of thyroidectomy animals, associated with reduced levels of thyroid hormone (T3). Thus we concluded that the thyroid hormones are directly related to functional changes in the retina of thyroidectomy animals, together with the reduction of weight and size.

Existe uma relação entre as frequências dos polimorfismos do gene TSHR e os marcadores de ancestralidade genética em pacientes com hipotireoidismo congênito primário?
(Universidade Federal do Pará, 2024-10) LOURENÇO, Victor Henrique Botelho; ALVES, Erik Artur Cortinhas; http://lattes.cnpq.br/9125390243566397; HTTPS://ORCID.ORG/0000-0001-8824-8075; SILVA, Luiz Carlos Santana da; http://lattes.cnpq.br/6161491684526382; https://orcid.org/0000-0003-1017-6221
Literature shows a correlation between ethnicities and pathogenic variants of the receptor TSH hormone gene (TSHR). Some of these polymorphisms can be as risk factors for the development of Primary Congenital Hypothyroidism (PCH). In this study, we investigate the relationship between the frequencies of TSHR gene polymorphisms with the genetic influence of African, Amerindian, and European ancestry informative markers in patients diagnosed with PCH in an Amazonian population in Brazil. The study was conducted on samples of 106 patients diagnosed with PCH. Genomic DNA was isolated from peripheral blood samples, and 10 exons from the TSHR were automatically sequenced. Ancestry-Informative Marker identification was performed using a panel of 48 markers, and the results were compared with parental Amerindian, Western European, and Sub-Saharan African populations using Structure v2.3.4 software. Four nucleotide alterations were identified among 49 patients. The distribution of tested ancestry markers among the 106 patients indicated a significant difference in the percentages of Amerindian (32.2%), European (41.80%), and African (25.9%) ancestry. A logistic regression analysis revealed no significant association between the rs2075179 and rs1991517 polymorphisms and genetic ancestry. This study found no evidence of a relationship between polymorphic TSHR gene variants and genetic ancestry markers in patients with PCH.
