Improvement of bone properties in children with osteogenesis imperfecta after pamidronate: a bone biopsy study.

OI, or bone brittle disease, is characterized by increased mineralization of bone matrix independently of clinical severity. So, a beneficial effect of antiresorptive treatments such as bisphosphonates (BP) is questionable. We aim to compare the bone matrix characteristics before and after BP pamidronate (PAM).

[Urinary incontinence in children].

URINARY INCONTINENCE IN CHILDREN. Urinary incontinence in children and adolescents is most often of functional origin. Questioning and clinical examination with a bladder diary should look for underlying urological or neurological causes.

Acute axonal neuropathy subtype of Guillain Barré syndrome in a French pediatric series: Adequate follow-up may require repetitive electrophysiological studies.

Different subtypes of Guillain Barré Syndromes (GBSs) are defined by their electrophysiological characteristics, acute inflammatory demyelinating neuropathy (AIDP), and acute motor/motor-sensory axonal forms (AMAN/AMSAN) with either reversible nerve conduction failure (RCF) or axonal degeneration. Our aim was to describe initial clinical and electrophysiological characteristics of axonal forms of GBS in a pediatric population and their short- and long-term evolution. Electroneuromyogram (ENMG) results were collected at diagnosis and at two months of evolution and interpreted using the recently proposed pattern of RCF vs axonal degeneration.

Unilateral predominance of abnormal movements: A characteristic feature of the pediatric anti-NMDA receptor encephalitis?

Anti-NMDA receptor encephalitis is a treatable autoimmune disease characterized by cognitive, motor and psychiatric features that primarily affects young adults and children. We present a case of a 7-year-old boy with asymmetrical (mainly right hemibody) and abnormal polymorphic movements without concomitant scalpictal EEG changes but had background slowing predominating over the left hemisphere. This report illustrates previous descriptions of asymmetric presentation of abnormal movements in pediatric anti-NMDA receptor encephalitis and emphasizes the importance of video-EEG interpreted within the overall clinical context, to differentiate epileptic from non-epileptic abnormal movements in patients with autoimmune encephalitis.
