Historical Article
The history of spinal surgery for disc disease: an illustrated timeline.
This article presents the evolution in medical history which leads to the surgical treatment for ruptured discs. Only at the last century the precise diagnosis of a ruptured lumbar disc could be made after tremendous efforts of the many medical pioneers in the study of the spine. The experience gained with the lumbar spine was rapidly transferred to the cervical spine. ⋯ Our understandings of the relation between symptoms and signs and of that between anatomy and pathophysiology have led to more successful surgical treatment for this disease. Nowadays lumbar and cervical discectomies are the most frequent operations carried out by neurosurgeons. Our current care of patients with this kind of spinal disorders is based on the work of our ancient medical heroes.

Ullrich congenital muscular dystrophy and Bethlem myopathy: clinical and genetic heterogeneity.
Ullrich congenital muscular dystrophy (UCMD), due to mutations in the collagen VI genes, is an autosomal recessive form of CMD, commonly associated with distal joints hyperlaxity and severe course. A mild or moderate involvement can be occasionally observed. ⋯ Bethlem myopathy should be considered in the differential diagnosis of UCMD, even in patients without fingers contractures; overlap between Ullrich and Bethlem phenotypes can be supposed.

Vestibular paroxysmia is a syndrome of cross-compression of the VIII cranial nerve and was first described by Jannetta who used the term "disabling positional vertigo". This syndrome is characterized by brief attacks of vertigo, tinnitus, vestibular and auditory deficits. MRI may show the VIII nerve compression from vessels in the posterior fossa, such as the basilar, vertebral, anterior-inferior cerebellar or the posterior-inferior cerebellar arteries. ⋯ This study describes eight patients with vestibular paroxysmia. Four of them showed also clinical signs suggesting cross-compression of the V and/or VII nerve. Seven patients treated with carbamazepine had significant improvement of vertigo and tinnitus.
