Abstract
Increased paternal age has been associated with an increased risk for autism spectrum disorders. The present study compared the paternal age distribution in autism spectrum disorders children with that of the general population and among children with attention deficit hyperactivity disorder. Study participants were drawn from the records of children diagnosed with one of these conditions in the years 1998-2006 at the Weinberg Child Development Center, Israel. Data regarding paternal age distribution in the general Israeli population were drawn from the yearly official publications of the Central Bureau of Statistics, Israel. Paternal age at the child's birth was found for autism spectrum disorders children (n = 268) and attention deficit hyperactivity disorders children (n = 320). Paternal age distribution of the attention deficit hyperactivity disorder children was similar to that of the general population in Israel, whereas autism spectrum disorders children were born to older fathers, compared with either the general population (P < 0.001) or children with attention deficit hyperactivity disorder (P = 0.04). These results support the claim that increased paternal age is associated with a birth of a child with autism spectrum disorders, but indicate that this finding cannot be generalized to attention deficit hyperactivity disorder.

Abstract
Osteochondrodysplasias like thanatophoric dysplasia, osteogenesis imperfecta, achondroplasia, and other genetic skeletal disorders like fibrodysplasia ossificans progressiva are infrequently seen in clinical practice. In cases of sporadic achondroplasia as well as in fibrodysplasia ossificans progressiva, there is a strong association with paternal age, a relationship that is less evident in other genetic osteochondral diseases. No other constitutional or environmental factor has proven to be associated with these disorders. The use of prenatal ultrasonography as a routine component of prenatal care is crucial in the early suspicion of osteochondrodysplasias whereas definitive diagnosis is usually obtained by pre-natal molecular analysis. In the case of fibrodysplasia ossificans progressiva, recognition of congenital great toe malformations associated with rapidly-appearing soft tissue swelling is sufficient to make the proper clinical diagnosis, which can be confirmed by genetic testing. Large regional centres will improve diagnosis performance, provide accurate genetic counselling, and ensure an integral assistance for these often severe and incapacitating conditions.
