objectives:the purpose of this study was to investigate of effects of sensory integration therapy (sit) on social interaction and sensory and motor performance in children with autism spectrum disorders (asd). methods:24 children with asd (22 boys, 2 girls), aged 6-12 years that matched on iq and gender, were randomly assigned to an experimental or control group. we requested participants of th...

congenital epulis is a very rare benign soft-tissue tumor of uncertain histogenesis, which is also known as “gingival granular cell tumor of the newborn”. it occurs almost exclusively as a single tumor along the alveolar ridge of the maxilla in newborn females. although congenital epulis is strikingly similar to the more common adult granular cell tumor histologically, in contrast to the latter...

Usher syndrome is the most prevalent cause of hereditary deaf-blindness, characterized by congenital sensorineural hearing impairment and progressive photoreceptor degeneration beginning in childhood or adolescence. Diagnosis and management of this disease are complex, and the molecular changes underlying sensory cell impairment remain poorly understood. Here we characterize two zebrafish model...

CONTEXT Hereditary peripheral neuropathies (hereditary motor-sensory neuropathies or hereditary demyelinating neuropathies) are abnormalities of Schwann cells and their myelin sheaths, with peripheral nerve dysfunction. They include Charcot-Marie-Tooth disease, Dejerine-Sottas disease, congenital hypomyelinating neuropathy and hereditary neuropathy with liability to pressure palsy. OBJECTIVE ...

Distinct preference for visual number symbols was recently discovered in the human right inferior temporal gyrus (rITG). It remains unclear how this preference emerges, what is the contribution of shape biases to its formation and whether visual processing underlies it. Here we use congenital blindness as a model for brain development without visual experience. During fMRI, we present blind sub...

Unsteady gait is a relatively common presentation to the pediatric emergency and neurology services. Unsteadiness can be due to a wide variety of causes, however, the primary concern on initial assessment is to exclude serious disorders such as meningitis, encephalitis, or brain tumors. Recognizing benign and non-neurological causes of unsteady gait is essential to avoid unnecessary investigati...

Congenital blindness is one of the rare human models to explore the role of experience-driven cross-modal compensation after early sensory deprivation. We re-examined spatial attention abilities in congenitally blind participants and sighted controls using a paradigm comparable to the one of our previous study (Collignon, Renier, Bruyer, Tranduy, & Veraart, 2006), except that this time the audi...

For the purpose of this paper, the term disability will encompass the following impairments: disability that can increase vulnerability to abuse resulting from physical, sensory, or mental impairments, or a combination of impairments; physical disability resulting from injury (e.g., spinal cord injury, amputation), chronic disease (e.g., multiple sclerosis, rheumatoid arthritis), or congenital ...

Pain protects the body from damaging effects of harmful stimuli. Congenital insensitivity to pain is a rare inherited disorder characterized by diminished or absent sensitivity to pain, touch, and pressure that leads to frequent trauma and self-mutilation. The disorder is part of the hereditary sensory and autonomic neuropathy (HSAN) family, in which 5 types have been recognized. Research and c...

Loss-of-function mutations in the SCN9A gene encoding voltage-gated sodium channel Nav1.7 cause congenital insensitivity to pain in humans and mice. Surprisingly, many potent selective antagonists of Nav1.7 are weak analgesics. We investigated whether Nav1.7, as well as contributing to electrical signalling, may have additional functions. Here we report that Nav1.7 deletion has profound effects...
