Each organ of a patient with the Down's Syndrome (trisomy 21) shows the pathology. One notices the specific features already with an infant. The life expectation of these children has increased considerably and it depends upon the appearance or not of a heart defect. The ventricular septum defect is most frequent but a small number of these patients show a complex cardiopathy. The incidence of pulmonary hypertension is also high. The obstruction of gastroenteric tract can cause problems from the prenatal phase onwards. The main endocrinological difficulties are dysfunction of the thyroid gland and also infertility. Ocular disorders like refraction disorders occur frequently. Due to decreased conduction, there is a hearing loss. The cellular immunity is clearly reduced, hence, the susceptibility to infections like hepatitis B, increases. The major oral problems are apparently oversized tongue and a high sensitivity to gingivitis.

This study determined the knowledge, attitude and practice of oral health care workers in public clinics in South Africa towards HIV/AIDS and investigated the implementation of infection control measures. A total of 727 questionnaires were distributed to dentists, dental therapists, oral hygienists and chairside assistants in the public dental clinics of 9 provinces, of which 276 were returned from 8 provinces, giving a response rate of 38%. The questionnaire covered demographic factors and assessed issues such as knowledge, infection control practices, continuing education, legal, ethical and psychosocial issues and available support for HIV/AIDS. The common oral manifestations seen by respondents were candidiasis, acute necrotising ulcerative gingivitis (ANUG), hairy leukoplakia and Kaposi's sarcoma. Of the 174 who had a previous HIV test, 48% were for insurance purposes and 21% for post-needle-stick injury. Over 10% of the respondents indicated that gloves were not available at all, that there was an inadequate supply of water, and that there was no autoclave in their clinic. Nearly 50% of the clinicians had not had hepatitis B vaccination in the last 3 years. Fifteen respondents (5.4%) were not willing to treat HIV-positive patients. Only 48% had access to a written post-exposure management protocol and post-exposure medication was available to only 36.6%. The vast majority of the respondents clearly expressed a need for additional education on HIV/AIDS. The study demonstrated a need to add knowledge, enhance personal skills and improve the application of universal precautions.
