Uncommon manifestations of histiocytosis X.

Histiocytosis X is a group of disorders of uncertain etiology with a variety of manifestations that are usually related to the age of the patient. Treatment consists of local curettage, irradiation and chemotherapy. The prognosis depends on the systems involved. The oral and perioral tissues are occasionally involved and often lead to the diagnosis. We report a case with spinal cord involvement and a case of facial nerve paralysis secondary to involvement of the petrosal bone. Also included is a case of involvement of the mandibular condyle.

Car transportation conditions of preschool children: use of children's car safety seats.

The objective of this study was to evaluate children's car safety seat usage in a non-random study population of the Capital and surrounding area of Attica and a provincial region in Greece. One or both of the parents of 1556 children (aged 0-4 years) were interviewed. A questionnaire covering car safety seat usage by area of residence, age of parents, educational background, socioeconomic status and the number of siblings was completed. Optimal car safety seat restraint usage in the Attica region was 10.4% for infants 0-6 months old, 37.6% for infants 7-12 months old, 40.9% for children aged 1-2 years and 12% for children aged 3-4 years; the use of restraint systems in the provincial area was even lower at 4.9%, 15.2%, 24% and 6.6%, respectively. The mother's age, number of children and the socioeconomic status of the family seemed to influence the purchase and usage of the car safety seat. Such a high percentage of non-usage of car safety restraint seats has led to the Paediatric Society's initiative to create informative general public educational programmes and to urge governmental legislation regarding mandatory usage of children's car safety seats.
