Global developmental delay (GDD), defined as a significant delay in two or more developmental domains (e.g., gross/fine motor, cognitive, speech/language, personal/social, activities of daily living), affects 1–3% of children. According to the Israeli Ministry of Health, thyroid function studies are not indicated in children with GDD unless there are systemic features suggestive of thyroid dysfunction (https://www.health.gov.il/hozer/mr36_2012.pdf). This approach also exists in other countries with newborn screening programs for congenital hypothyroidism.

We present the case of an infant with GDD, who despite normal newborn screening tests, underwent a repeated extended thyroid function analysis (including T₃ levels) leading to a diagnosis of Allan-Herndon-Dudley syndrome, a rare genetic neurodevelopmental syndrome.

Background: Several studies have suggested that iron deficiency may be related to the pathophysiology of attention deficit hyperactivity disorder (ADHD) due to the role of iron in the production of dopamine and noradrenaline.

Objectives: To evaluate the status of iron deficiency in ADHD children, using ferritin levels, a reliable measure of iron storage in body tissue, as an iron status marker, and to investigate a possible correlation between ferritin levels and the diagnosis of ADHD.

Methods: The study group included 113 newly referred ADHD children aged 5–15 years (mean age 8.8 ± 2.7).

Results: Ferritin levels were below 20 ng/ml in 67 children (59%) and above 20 ng/ml in 45 (41%). There was a very low inverse statistical correlation between scores on Conners’ Rating Scale and ferritin levels, probably without clinical significance. 

Conclusions: Our findings suggest that low iron stores may be related to ADHD pathophysiology; therefore, ferritin should be included in the overall evaluation of children with ADHD.

Background: In the developing child the nervous system undergoes a maturation process. The development and organization of any motor ability is the naturally adopted preference among the possibilities and constraints. The motor behavior of children with cerebral palsy is a personal automatic preference based on such constraints. One of the clinical measures designed for measuring the function of children with CP[1] is the Gross Motor Function Measure. Motor development curves for children with CP have been established based on the GMFM[2] instrument and Gross Motor Function Classification System.

Objectives: To examine the change over time in gross motor function for children with CP attending a special education school for handicapped children in Israel.

Method: We conducted a retrospective review of the medical records of children at various ages and with varying degrees of severity who were being treated by a multidisciplinary team. The study population comprised 106 children aged 3–8 years with CP who were attending the school of special education at Assaf Harofeh Medical Center. The GMFM-88 test was performed annually for the study children over a 7 year period (1995–2001).

Results: During the study period the GMFM measures scores improved significantly. The rate of improvement and top achievements over the years differed according to the severity of the motor impairment. The gross motor development reached a plateau at the age of 6–7 years.

Conclusions: The changes in gross motor development of the study population were similar to the profile of changes in the developmental process of children who develop normally. The nature of the curves of gross motor change for the children with CP should be borne in mind when designing individual treatment goals and strategies for a child.
