Spontaneous fracture of atlas of cervical spine affected by rheumatoid arthritis.

A case of spontaneous fracture of the atlas in a 67-year-old woman who had suffered from rheumatoid arthritis for more than 20 years is described. This fracture is unique and can present diagnostic problems. Lying in the coronar plane makes the atlas difficult to visualize radiographically. Computer-guided tomography is a helpful diagnostic technique. The brittleness of the cervical spine in long-term rheumatoid patients should also be kept in mind when performing endotracheal intubation.

Serum, Cell-Free, HPV-Human DNA Junction Detection and HPV Typing for Predicting and Monitoring Cervical Cancer Recurrence.

Almost all cervical cancers are caused by human papillomaviruses (HPVs). In most cases, HPV DNA is integrated into the human genome. We found that tumor-specific, HPV-human DNA junctions are detectable in serum cell-free DNA of a fraction of cervical cancer patients at the time of initial treatment and/or at six months following treatment. Retrospective analysis revealed these junctions were more frequently detectable in women in whom the cancer later recurred. We also found that cervical cancers caused by HPV types outside of phylogenetic clade α9 had a higher recurrence frequency than those caused by α9 types in both our study and The Cancer Genome Atlas cervical cancer database, despite the higher prevalence of α9 types including HPV16 in cervical cancer. Thus, HPV-human DNA junction detection in serum cell-free DNA and HPV type determination in tumor tissue may help predict recurrence risk. Screening serum cell-free DNA for junctions may also offer an unambiguous, non-invasive means to monitor absence of recurrence following treatment.

Sleep attacks--apparent relationship to atlantoaxial dislocation.

Sleep attacks, while being characteristic of narcolepsy, have been reported in several metabolic and central nervous system disorders--most of which are refractory to treatment. We have recently treated a 47-year-old man with disabling sleep attacks who was found to have atlantoaxial dislocation. Despite narrowing of the sagittal cervical canal diameter to 12 mm (behind the dens), symptoms of spinal cord compression were mild and intermittent, while signs were absent. Posterior fusion of the C-1 and C-2 vertebrae resulted in relief of symptoms. We suggest that this sleep disorder was a function of impaired efferent control of respiration.

Craniospinal and cervicospinal malformations associated with maxillonasal dysostosis (Binder syndrome).

Craniospinal and cervicospinal malformations were found in 15 (53.5%) of 28 cases of maxillonasal dysostosis (Binder syndrome) in which a complete radiographic analysis could be done. These anomalies have not been reported previously. Analysis of the anomalies suggested a common induction factor, or, at least, a simultaneity in the development of the maxillonasal and vertebral dysplasias that characterize Binder syndrome. The following procedures are recommended: (1) examination of the cranial and cervical spine in all subjects with symptoms of Binder syndrome, and (2) regular examination of patients with spinal malformations, so that any neurologic damage may be detected early.

Pathology of the cervical spine in rheumatoid arthritis: a controlled study of 44 spines.

Cervical spines (with occiputs) of 44 patients with rheumatoid arthritis (RA) were compared with 44 control spines from patients without RA, matched for sex and age. There were six severe and seven slight atlanto-axial dislocations (both horizontal and vertical, two of which had been treated surgically) in the RA group and none in the control group. Ankylosis, synchondrosis, syndesmosis, bone erosions, and redness of synovial tissue in the atlanto-axial, atlanto-occipital and cervical intervertebral joints were more frequent in the RA group than in the control spines. The lesions permitting the best discrimination between the RA and control groups were used to calculate an overall score for the whole cervical spine. Sixteen of the 44 RA patients scored higher than the highest control value; only nine scored lower than the median control score. A higher score than the average value found for the RA spines was obtained by the male patients, the patients with seropositivity or subcutaneous nodules, the patients treated with corticosteroids, the patients who died in the Department of Rheumatology, and those whose death was related to the RA itself or to the treatment given.

[Severe trauma of neck and skull base ].

The concept of internal decapitation comprises lesions within the skull base, upper spinal column with partial or complete destruction of the cervical part of the medulla. By means of casualties due to internal decapitation we demonstrate that, besides the known causes, a rotational damage at the juncture of the upper spinal column to the skull base as well as fractures by axial stretching may cause such traumas. A decrease of such accident's consequences is hardly possible because of the amount of energy involved causing the damage. Due to a steady increase of traffic, particularly by motor-bicycle, we shall have to cope with more cases of this kind of damage.

Computer tomography for lesions of the craniovertebral region.

The images obtained by computed tomography constitute a new and interesting approach to lesions of the craniovertebral region. The criteria of basilar invagination must be systematically checked in routine examination. The main interest of CT scanning is the simultaneous view of the bony structures as well as the central nervous system in a completely innocuous way.

The radiology of rheumatoid involvement of the cervical spine.

The radiological features of cervical spine involvement in rheumatoid arthritis are described. These include atlanto-axial subluxation, in both the horizontal and vertical planes, sub-axial dislocation, erosions, and vertebral end plate sclerosis. Detailed radiological investigation, using inclined plane radiography, auto-tomography, tomography, and myelography may all be required to demonstrate the abnormalities. Disorders of mobility can only be assessed with dynamic views and fluoroscopy and the mechanics of these derangements vary depending on the type of subluxation encountered. The cumulative effects of the lesions conform to certain characteristic patterns and include marked reduction of neck height, disorders of mobility, and changes in the capacity of the spinal canal. The discrepancy between these changes and the clinical and neurological findings is discussed.

Posterior atlanto-axial fusion: a new compression clamp for laminar osteosynthesis.

A new method of dorsal arthrodesis in patients with atlanto-axial instability of different etiology is described. In three patients solid laminar osteosynthesis C1/C2 was achieved by insertion of an autogenous cortico-cancellous bone graft into the interlaminar space and by a bilateral application of the lately developed metal clamp. The technical principles of the clamp guarantee a permanent pressure on the graft and a solid initial stability in the segment. Additional external fixation and immobilization of the patient are not necessary. Complications as known from other procedures of the atlanto-axial dorsal fusion will be prevented efficiently.
