Oral Health Profiles and Related Quality of Life in Thalassemia Children in Relation to Iron Overload: A Cross-Sectional Study.

The aim was to assess the oral health of children with ß-thalassemia major (BTM) and their oral health-related quality of life (OHRQoL) in relation to the serum ferritin level (SFL). Thirty-nine children with BTM underwent an interview, salivary sampling and an oral clinical examination. The Early Childhood Oral Health Impact Scale (ECOHIS) was used to assess their OHRQoL. The mean age of the participants was 9 ± 3 years, with 62% females. The body mass index and salivary secretion rate were within normal ranges. The mean plaque index, gingival bleeding index and number of decayed, missing and filled tooth surfaces were 70 ± 29, 38 ± 25 and 3.2 ± 4, respectively, with no significant differences between individuals with SFL below or above 2000 ng/mL (p > 0.05). No significant differences were observed between the two groups in any of the ECOHIS questions (p > 0.05). The mean ECOHIS score was 4.2 ± 4. Individuals with SFL ≥2000 ng/mL had a significantly higher mean score in the family domain "Parent Distress" than those with lower SFL (p ≤ 0.05). Within the study limits, children with ß-thalassemia major generally had high dental caries experience and gingival inflammation, yet an acceptable OHRQoL. Those with high SFL had less favorable scores in the domain "Parent Distress".

Assessment of cardiac functions in children with sickle cell anemia: doppler tissue imaging study.

BACKGROUND AND AIMS: The extent in which sickle cell anemia (SCA) impacts myocardial function in children is unclear. Doppler tissue imaging (DTI) was introduced as a new non-invasive echocardiographic method for assessment of ventricular systolic and diastolic functions. We undertook this study to assess subclinical impact of SCA on global myocardial performance in affected children using DTI and to correlate it with mean hemoglobin concentration. METHODS: Eighty five children with SCA (mean age 11.82 ± 3.7 years) was included as the study group and 55 age- and sex-matched healthy children as the control group. Conventional two-dimensional echocardiography was performed in both groups and DTI was used to determine right ventricular (RV) and left ventricular (LV) Tei indexes. Mean Hb concentration was correlated to the cardiac functions of SCA children. RESULTS: RV and LV Tei indexes were significantly higher in SCA group (mean ± SD: 0.54 ± 0.19 vs. 0.27 ± 0.01, p <0.0001 and 0.47 ± 0.09 vs. 0.30 ± 0.07, p <0.0001, respectively). Also, mean Hb concentration was correlated negatively with both LV Tei index (r = -0.611, p <0.0001) and with RV Tei index (r = -0.894, p <0.0001). On the contrary, fractional shortening (FS) did not correlate with mean Hb concentration (r = -0.044, p = 0.681). CONCLUSIONS: DTI technique appears to be more sensitive than conventional echocardiography in the early detection of myocardial dysfunction in children with SCA. This provides insights into the value of early screening and the potential for preventive therapy in children to avert cardiac morbidity and mortality in adults with SCA.
