As well as the long-T2 relaxation components normally detected with conventional imaging techniques, the brain has short-T2 components. We wished to use ultra-short (0.08 ms) echo time (UTE) pulse sequences to assess the feasibility of imaging these in normal subjects and patients. UTE sequences were employed, with or without fat suppression, 90 degree(More)
A 54 year old man is described with signs compatible with ocular myasthenia gravis and an apparent excellent response to pyridostigmine. Subsequent clinical progression and further investigation suggested the presence of an inflammatory brain stem lesion, which responded to corticosteroid therapy. Clinical relapse, including the development of central(More)
Krabbe's disease (globoid cell leucodystrophy) is a disorder involving the white matter of the peripheral and central nervous systems. Mutations in the gene for the lysosomal enzyme galactocerebrosidase (GALC) result in low enzymatic activity and decreased ability to degrade galactolipids found in myelin. The disease is classically of infantile onset, but(More)
OBJECTIVE Determination of the efficacy of pulsed Alexandrite Laser technology for rapid noninvasive hair removal. SUMMARY BACKGROUND DATA Although previous studies have already shown that Ruby lasers are capable of noninvasive hair removal, a technology for the substantial increase of treatment speed is of great interest. METHODS We have used a 2 msec(More)
The use of bilateral hearing aids is based on the assumption that the human auditory system functions best when both ears receive incoming acoustic information. There is evidence, however, that some elderly individuals perform better while using unilateral as opposed to bilateral amplification. The main objective of the present study was to compare speech(More)
Neuromyelitis optica (NMO) is an inflammatory autoimmune disease of the central nervous system that preferentially targets the optic nerves and spinal cord. The clinical presentation may suggest multiple sclerosis (MS), but a highly specific serum autoantibody against the astrocytic water channel aquaporin-4 present in up to 80% of NMO patients enables(More)
BACKGROUND Laser-assisted hair removal with the long pulsed ruby laser is a promising new technique based on selectively targeting melanin in hair follicles. OBJECTIVE The purpose of this study was to evaluate the efficacy and safety of the long pulsed ruby laser (EpiTouch) for hair removal. METHODS The Epitouch laser was used for hair removal of the(More)
The method for laser and light assisted hair removal is based on the theory of selective photothermolysis. Selective absorption of hair chromophores from lasers and broad band light sources results in destruction of hair follicles while leaving the skin undamaged. A discussion of the basic principles of selective photothermolysis as it applies to hair(More)
The differential diagnosis of subacute onset ataxia in the setting of enteropathy is wide. A 54 year old patient with a pancerebellar syndrome and known ulcerative jejunoileitis is described. Small bowel biopsy showed evidence of enteropathy associated T cell lymphoma and subsequent neuropathological analysis and immunophenotyping confirmed metastasis of(More)
The psychotropic effect of Elroquil has been studied in 13 cats (8 of them having electrodes implanted in the hypothalamus). Diazepam was used as the reference drug. By electrical stimulation of the brain structures various states of excitation, such as rage, anxiety, restlessness and negation could be provoked. Evaluation was made by a scoring scale and(More)
