    Evaluation of panoramic radiomorphometric indices related to low bone density in sickle cell disease

    In sickle cell disease, erythroid hyperplasia causes trabecular destruction leading to low bone density. This condition could be suspected by the radiomorphometric indices and your diagnosis becomes relevant in a multidisciplinary context of health care for sickle cell subjects, providing prognostics and contributing to determine adequate therapeutic and preventive actions. The aim of this study was to assess the risk of low bone density in subjects with sickle cell disease (SCD) through analysis of panoramic radiographic exams by radiomorphometric indices. Seventy-eight Brazilian subjects with SCD took part in this study and were subdivided into four groups: (I) 31 SCD subjects aged under 40 years; (II) 13 SCD subjects aged 40 years or more; (III) 12 normal subjects aged under 40 years; and (IV) 22 normal subjects aged 40 years or more. In the panoramic radiographs, the mandibular cortical index (MCI) classification, increased spacing of the trabecular bone, panoramic mandibular index (PMI), and mental index (MI) were evaluated. Exact Fisher's test was used to compare age between the different groups. Descriptive analysis of the data was performed to evaluate the simple visual estimation of low bone density (increased bone trabecular space and MCI), and a one-way analysis of variance (Bonferroni criteria) was used to compare the means of the quantitative indices (PMI and MI). The significance level was p < 0.05. In the MCI classification, C2 was more prevalent, especially in groups I and IV. Increased spacing of the trabecular bone was more frequent in groups I and II. MI did not show a statistically significant difference among the groups. PMI showed a statistically significant difference only between groups III and IV. The radiomorphometric indices applied in the present study can be used on panoramic radiographs to detect the presence of low bone density in SCD subjects.23720372042FAPESB (Bahia Research Support Foundation

    O objetivo deste estudo foi avaliar o efeito da duração da amamentação exclusiva e mista sobre os níveis de hemoglobina de lactentes. Trata-se de um estudo de seguimento com seis meses de duração, envolvendo 150 crianças nascidas na maternidade de Mutuípe, Bahia, Brasil. Mensalmente, as crianças eram submetidas ao exame de sangue para avaliação dos níveis de hemoglobina e realizava-se coleta de dados de consumo alimentar. Foram obtidos, ainda, dados obstétricos e sócio-econômicos. Utilizou-se o modelo linear de efeitos mistos para investigar as associações de interesse. Ao final do seguimento, a perda amostral foi de 15,3%, e detectou-se uma prevalência de 71,7% de anemia. Constatou-se um incremento de 0,091g/dL nos níveis de hemoglobina a cada mês de duração de aleitamento materno exclusivo (p = 0,031), enquanto, a cada mês de duração de aleitamento materno misto, os níveis de hemoglobina declinaram em 0,097g/dL (p = 0,017). Concluiu-se que as práticas alimentares inadequadas parecem estar diretamente envolvidas na etiologia da deficiência nutricional de ferro nesse período da vida.<br>This six-month follow-up study aimed to assessing the effect of length of both exclusive breastfeeding and mixed feeding on hemoglobin levels in 150 infants born at the Mutuípe maternity facility in Bahia State, Brazil. Blood tests were performed monthly to assess the hemoglobin levels, at which time data were gathered on food intake. Obstetric and socioeconomic data were also collected. The linear mixed effects model was used to investigate the target associations. Loss to follow-up was 15.3%, and anemia prevalence was 71.7%. An increase of 0.091g/dL (p = 0.031) in hemoglobin levels was found for each month of exclusive breastfeeding, while a decrease of 0.097g/dL (p = 0.017) was shown for each month of mixed feeding. In conclusion, inadequate food practices appear to be directly involved in the etiology of iron deficiency anemia during infancy
