We used freeze-thawed muscle grafts to restore continuity to the affected nerve in 22 painful cutaneous neuromas. In 11 of the 15 neuromas in the upper limb, pain was partially or completely relieved; in six of these there was some recovery of distal sensation. Partial pain relief was achieved in only two of the seven neuromas in the lower limb. The difference is attributed to the longer grafts...

Seven patients with meningiomas and five patients with neuromas were examined with spin-echo sequences on a 0.35-T imaging system. Signal enhancement and relaxation rate increments with gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) were evaluated, as well as relaxation rate contributions, indicators of Gd-DTPA accessibility to the tissue water. The average signal enhancement rate wit...

OBJECTIVE Determine whether auditory cortex (AC) organization changed following eighth cranial nerve surgery in adults with vestibular-cochlear nerve pathologies. We examined whether hearing thresholds before and after surgery correlated with increased ipsilateral activation of AC from the intact ear. STUDY DESIGN During magnetic resonance imaging sessions before and 3 and 6 months after surg...

N eurofibromatosis type 1 (NF-1) is a genetic disorder predominantly affecting tissues derived from neural ectoderm producing a multifocal neurocutaneous disease. It is usually inherited as an autosomal dominant trait with variable penetrance and phenotypic expression, affecting one in 2500-3300 live births. A closely related condition, neurofibromatosis type-2 (NF-2) occurs much less frequentl...

BACKGROUND Whether or not there is a relationship between use of mobile phones (analogue and digital cellulars, and cordless) and head tumour risk (brain tumours, acoustic neuromas, and salivary gland tumours) is still a matter of debate; progress requires a critical analysis of the methodological elements necessary for an impartial evaluation of contradictory studies. METHODS A close examina...
