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.

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.

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.

CT and MRI in hydatid disease of cervical vertebrae.

Hydatid disease (HD) of the cervical spine is rare. A case investigated by computed tomography (CT) and magnetic resonance imaging (MRI) is presented. While CT shows the bone lesion better, MRI is superior in demonstrating compression of neural structures. The complementary use of CT and MRI in such cases is suggested.

Craniocervical junction malformation treated by transoral approach. A survey of 25 cases with emphasis on postoperative instability and outcome.

An experience with 25 consecutive cases of craniocervical junction (CCJ) malformations operated upon via the transoral route is reported. Twenty-two patients also underwent posterior occipito-cervical stabilization with alloplastic material and in only one patient was transoral odontoidectomy and fusion with bone autograph performed. Indication for the transoral route consisted of an irreducible ventral compression of the cervicobulbar junction by the abnormal bone complex. Two patients died during the early postoperative period and the remaining 23 survivors were followed for an average of 3.5 years: 17 of these showed marked improvement and 5 a stabilization of the neurological disturbances. A further patient, who refused posterior stabilization, eventually died because of progressive cranial settling. Long-term results have shown this approach to be decisive in the surgical management of well-selected CCJ anomalies.

Non-operative management of acute upper cervical injuries.

The results of a closed, non-operative type of treatment in acute upper cervical injury have been reviewed, especially as they relate to the use of the halo cast or vest. The morbidity with the use of this device has been minimal and there has been no mortality. Early patient mobilization has been readily achieved and in the case of the Hangman's, Jefferson's, and odontoid fractures, stable solid bony healing has been achieved in nearly all cases. Similar results have been noted in the C-1 arch fracture, as well as the acute post-infectious subluxations of C-1/C-2. In a small number of cases involving traumatic C-1/C-2 and occipital/atlas subluxation, there has occurred a significant incidence of instability, despite adequate closed treatment. This has been likely to be due to the serious ligamentous disruption in these cases and it would appear that surgical fusion may be the preferential form of initial treatment in this group of injuries.

[Fractures and dislocations of the cervical spine caused by hanging (author's transl)].

In comparison to the pattern of lesions of the soft tissue of the neck and the CVC in case of suicidal hanging 17 postmortal fracture-dislocations of the neck are investigated. It could be demonstrated that on principle in case of hanging the dens-fracture can occur. With respect to the hangman's fracture (Wood-Jones) a differentiation into 3 types is proposed.

The ring of C2 and evaluation of the cross-table lateral view of the cervical spine.

The cross-table lateral view is essential in the initial workup of a trauma patient with a suspected cervical-spine injury. The identification of the radiographic "ring" of C2 on the cross-table lateral view is discussed. When a type III odontoid fracture is present, the ring of C2 is disrupted. We propose that "identification of the ring of C2" should be added to the emergency physicians' systematic checklist when clearing a cross-table lateral view of the cervical spine.

Comparison of mandibular growth with other variables during puberty.

The purpose of this investigation was to compare growth characteristics of the mandible during puberty with growth characteristics of the hyoid bone, cervical vertebrae, hand bones and standing height. Data were compiled from serial lateral cephalometric roentgenograms, hand-wrist roentgenograms and body height records of 33 Japanese girls between 9 and 14 years old. Records were updated annually. The mandibular growth rate differed from the other growth rates. The timing of maximum growth velocity of the mandible varied more widely than the timing of maximum growth velocity of the other parameters measured, and the total amount of mandibular growth did not correlate to any other measurement. The timing and magnitude of circumpubertal growth acceleration of various components of the body vary within a certain range of difference. However, the amount and timing of mandibular growth seems to be more variable than the other areas studied.

[Dorsal stabilization in dislocated fractures of C-1 and C-2 vertebrae with Palacos and wiring].

During 1 year 6 patients with dislocated fractures of C-1 and C-2 vertebrae (fractures of the odontoid process) and 1 patient with a pseudarthrosis of the odontoid process have been treated. 6 patients have been treated surgically by internal fixation of the arch of C-1 and C-2 spinous process by wiring and plastic material (Palacos). No complications occurred. The advantage of the method was early mobilization of the patients and reduction of hospitalization. Clinical and radiographic follow-up studies showed stable fusion on Flexion-extension X-rays and boney union of the fracture of the odontoid process.

[Changes in the cervical spine in juvenile rheumatoid arthritis (author's transl)].

Changes in the cervical spine in juvenile rheumatoid arthritis can be shown by A.P., lateral and functional views with maximal flexion and extension, and particularly by tomography. The latter is essential for proper evaluation of the atlanto-occipital and atlanto-axial joints and of the odontoid. Atlanto-axial subluxation was found in eight out of eighty-four patients. Destruction of the odontoid was found in twelve out of fifty-three patients examined by tomography. The earliest tomographic changes at the atlanto-occipital joint consists of isolated joint narrowing, erosions and fusion and were observed in sixty-four out of sixty-six patients examined. Similar findings at the atlanto-axial joint were observed in thirty-seven out of sixty-six cases. The severity of the changes correlated with seropositivity and duration of the disease. The most marked changes were found with a prolonged history and a positive Rose-Waaler reaction.

Computed tomography of spinal fractures.

Computed tomography (CT) has aided significantly in the diagnosis and management of spinal fractures. The examination is easy, relatively quick, and avoids potentially harmful manipulation. The diagnostic advantages of CT include precise anatomic delineation and indication of extent of fractures, assessment of spinal stenosis, and demonstration of associated peraspinal lesions.
