Medical conditions of children and young people with Down syndrome.

BACKGROUND: The life expectancy of people with Down syndrome (DS) has significantly increased in the last decades. We describe the congenital malformations and main comorbidities of a cohort of children and young people with DS and analyse their differences according to age and gender groups. METHODS: This retrospective cross-sectional study was conducted at DS centre of Bambino Gesù Children's Hospital in Rome (Italy). The period for reviewing all electronic health records ran from July 2016 to September 2017. We collected data on clinical conditions and compared them with the general paediatric population. Moreover, we compared the main comorbidities, dental diseases and body mass index data between age groups. RESULTS: Seven hundred sixty-three children and young people with DS included in this study were aged 7.45 ± 5.49 years. Gender distribution included 58.19% male patients. The majority of our population (71.04%) came from central regions of Italy. Respiratory diseases (19%), congenital heart defects (72.23%), malocclusions (58.62%), astigmatism (20.31%), farsightedness (16.51%), near-sightedness (12.19%) and autoimmune hypothyroidism (3.28%) were more frequent in our population compared with the typical paediatric population. Upper respiratory tract infections and underweight were significantly more frequent in the youngest children, whereas dental diseases, refractive errors, obesity and autoimmune hypothyroidism increased over age. CONCLUSIONS: Children and young people with DS present a high prevalence of potentially treatable medical conditions making multidisciplinary teams a mandatory need for this population.

Evaluation of the relationship between obesity, dental caries and periodontal disease in adolescents.

AIM: To assess the prevalence of caries, oral hygiene quality and periodontal disease in a cohort of obese adolescents compared to a control group. MATERIALS AND METHODS: Study Design: cross-sectional study conducted on 204 subjects (age range 10-16 years). Ninety obese subjects (BMI >90) and 114 normal-weight subjects (BMI <75) were visited at the Bambino Gesù Children's Hospital and in a junior high school in Rome, respectively. An ad hoc questionnaire (investigating demographic and oral health behaviour data) was filled in by patients and their caregivers. Accurate oral examinations were conducted. The Decayed-Missing-Filled Teeth/Surfaces Index in both permanent (DMFT/DMFS) and primary dentition (dmft/dmfs), Gingival Bleeding Index (GBI), Visible Plaque Index (VPI), and Probing Depth (PD) were recorded. STATISTICS: data analysis was carried out using the Statistical Package for the Social Sciences (SPSS 21.0; SPSS IBM, New York, NY). The data of the two groups were compared by means of Student's t Test or the Mann-Whitney test for numerical data and the Chi-square test for categorical data. RESULTS: Patients affected by obesity, compared with controls, presented less compromised teeth in the primary dentition (dmft obese: 0.30 ±± 1.12; normal-weight: 1.00 ± 1.90; P<0.001) and less compromised dental surfaces (dmfs obese: 0.51 ± 2.14; normal-weight: 1.61 ± 3.10; P<0.001). Furthermore obese patients showed minor gingival inflammation with less bleeding on probing (GBI) (obese: 23.95 ± 21.43; normal-weight: 38.17± 24.37; P<0.001), and less probing depth in a greater number of sites (PPD ≤ 3) (obese: 101.92 ± 9.27; normal-weight: 97.28 ± 12.13; P<0.001). Moreover, the obese group showed a better oral hygiene (VPI) (obese: 25.69 ±25.83; normal-weight: 37.72 ±24.34; P<0.001). CONCLUSION: In our study, obese adolescents showed a better oral hygiene, fewer compromised teeth and better periodontal health when compared with normal-weight patients.
