Other spinal abnormalities associated with DSS include widened intervertebral disks, small, dense vertebral bodies, irregular vertebral endplates, hypoplastic vertebral bodies, and pronounced vertebral anterior notches.More than 80% of patients also reported abnormalities of the skull. Common symptoms include craniofacial hyperostosis, which is the excessive growth of bone in the skull and face. Skull base sclerosis, periorbital sclerosis, hypoplastic mandibular condyle, and absent paranasal or frontal sinuses are present in rare cases.It is also reported that individuals may also have pelvic abnormalities. This includes the development of narrow iliac wings, as well as widened femoral necks. However, incidence of both symptoms are rare in patients with DSS, occurring in less than 30% of cases.The occurrence of DSS also leads to deformities of the limbs. 80% of patients reported with abnormalities of the metaphysis such as metaphyseal flaring, radiolucent metaphyses, abnormal metaphyseal trabeculation, which is abnormal trabecula patterns in the metaphyseal region, and epimetaphyseal sclerosis. Other limbic abnormalities include progressive bowing of long bones, which is present in rare cases. Physical abnormalities
In general, patients appear to be short statured. In addition, as a result of sclerosis of the frontal and parietal region of the calvarium, macrocephaly and square shaped heads are reported in more than 80% of patients.Abnormal skin conditions of red-violet macular mottled skins over the entire body are occasionally observed in patients. However it is unclear whether this clinical feature is relevant to diagnosis of DSS. Neurological abnormalities
Visual problems are often found in people with DSS.
However the trend of substituting sweetened drinks for milk has been found to lead to excess weight gain. Legal
Some jurisdictions use laws and regulations in an effort to steer children and parents towards making healthier food choices. Two examples are calorie count laws and banning soft drinks from sale at vending machines in schools. In the United Kingdom the Obesity Health Alliance has called on whichever party wins the general election to take measures to reduce childhood obesity, for example by banning advertisements for unhealthy foods before 9:00 pm and banning sports sponsorship by manufacturers of unhealthy foods. The failure of the present UK government to cut sugar, fat and salt content in foods has been criticised. Health experts, the health select committee and campaigners described Conservative plans over childhood obesity as, "weak" and "watered down". Physical activity
Physical inactivity of children has also shown to be a serious cause, and children who fail to engage in regular physical activity are at greater risk of obesity. Researchers studied the physical activity of 133 children over a three-week period using an accelerometer to measure each childs level of physical activity. They discovered the obese children were 35% less active on school days and 65% less active on weekends compared to non-obese children. Physical inactivity as a child could result in physical inactivity as an adult.
