Developmental Umbilical Abnormality

An Unusual Developmental Abnormality of the Arms

Spatial attention deficits in patients with acquired or developmental cerebellar abnormality.

Recent imaging and clinical studies have challenged the concept that the functional role of the cerebellum is exclusively in the motor domain. We present evidence of slowed covert orienting of visuospatial attention in patients with developmental cerebellar abnormality (patients with autism, a disorder in which at least 90% of all postmortem cases reported to date have Purkinje neuron loss), an...

OEIS Complex: developmental insights into a severe congenital abnormality of body wall development

White Matter Abnormality Correlates with Developmental and Seizure Outcomes in West Syndrome of Unknown Etiology.

BACKGROUND AND PURPOSE West syndrome is an epileptic encephalopathy characterized by epileptic spasms, a specific pattern on electroencephalography of hypsarrhythmia, and developmental regression. Our aim was to assess white matter abnormalities in West syndrome of unknown etiology. We hypothesized that diffusion tensor imaging reveals white matter abnormalities, especially in patients with poo...

Autoimmune disease as a consequence of developmental abnormality of a T cell subpopulation

Neonatal thymectomy (NTx), especially around day 3 after birth, causes various organ-specific autoimmune diseases in mice. This report shows that: (a) T cells expressing the interleukin 2 receptor alpha chains (CD25) ontogenically begin to appear in the normal periphery immediately after day 3, rapidly increasing within 2 wk to nearly adult levels (approximately 10% of CD3+ cells, especially of...
