Can Magnetic Resonance Imaging Reveal Lower Motor Neuron Damage after Traumatic Spinal Cord Injury? A Scoping Review.

Restoring muscle function to patients with spinal cord injuries (SCIs) will invariably require a functioning lower motor neuron (LMN). As techniques such as nerve transfer surgery emerge, characterizing the extent of LMN damage associated with SCIs becomes clinically important. Current methods of LMN diagnosis have inherent limitations that could potentially be overcome by the development of magnetic resonance imaging (MRI) biomarkers: specific features on MRI that are indicative of LMN integrity.

[Hypothalamic hamartomas: control of seizures after partial removal in one case].

Objective: To describe a patient with intractable seizures and hypothalamic hamartoma that was only partially resected with complete control of seizures and improvement in behavior after surgery.

Clinical Case: He had gelastic seizures from the first months of life associated with hypothalamic hamartoma. We used magnetic resonance spectroscopy to localize and measure the lesion in the temporal lobes and in the hamartoma.

Arteriovenous malformation in hypomelanosis of Ito.

Hypomelanosis of Ito (HI) is a neurocutaneous syndrome with multisystemic involvement. Its most frequent neurological abnormalities are mental retardation and seizures. EEG, CT and MRI findings are not characteristic enough to be diagnostic.

Diffraction theory of optimized low-resolution Fresnel encoded lenses.

A mathematical model describing the behavior of low-resolution Fresnel encoded lenses (LRFEL's) encoded in any low-resolution device (e.g., a spatial light modulator) has recently been developed.

[Neuro-urologic impact of spinal cord untethering in patients with myelomeningocele and tethered cord].

Changes in bladder behaviour and neurological symptoms were evaluated in 47 patients underwent untethered spinal cord because of tethered cord syndrome secondary to myeloneningocele closure. Patients were located in 3 categories (A < or = 5 years, B 6-10 years and C > 10 years) in relation to age of treatment. After untethering 77% improved neurologically and the best results were evident in children whose condition was repaired promptly (90%).
