Diabetic thoracic radiculopathy: a case of a young woman with clinical improvement following immunotherapy.

2020

Thoracic radiculopathy is a rare cause of thoracic-abdominal or abdominal pain in subjects with poorly controlled diabetes. We present a case of a young woman with type I diabetes and a severe abdominal pain in both lower quadrants. An extensive diagnostic gastroenterological and gynaecological workup did not disclose abnormalities. Electromyography revealed an initial polyneuropathy and significant neurogenic abnormalities in the T10-T12 paravertebral muscles. Following the hypothesis that the radiculopathy-related abdominal pain might have an immuno-mediated pathogenesis, the patient underwent a complex trial of immunotherapy, which was accompanied by a sustained improvement over months t…

Childhood growth predicts higher bone mass and greater bone area in early old age: findings among a subgroup of women from the Helsinki Birth Cohort …

2017

Abstract Summary: We examined the associations between childhood growth and bone properties among women at early old age. Early growth in height predicted greater bone area and higher bone mineral mass. However, information on growth did not improve prediction of bone properties beyond that predicted by body size at early old age. Introduction: We examined the associations between body size at birth and childhood growth with bone area, bone mineral content (BMC), and areal bone mineral density (aBMD) in early old age. Methods: A subgroup of women (n = 178, mean 60.4 years) from the Helsinki Birth Cohort Study, born 1934–1944, participated in dual-energy X-ray absorptiometry (DXA) measuremen…

Can the transverse foramen/vertebral artery ratio of double transverse foramen subjects be a risk for vertebrobasilar transient ischemic attacks?

2018

The C6 is the cervical vertebra into which the vertebral artery enters the passage of the transverse foramen and it is the vertebra most affected by double transverse foramina. There is currently little information about the relation between the vertebral artery and the double transverse foramen in C6. We aimed to test whether subjects with a double transverse foramen in C6 have a reduced transverse foramen/vertebral artery ratio when compared with normal anatomy subjects who possess a single transverse foramen which may be a risk for transient vertebral artery stenosis. We measured the area of the transverse foramen and the vertebral artery in 27 double transverse and 56 normal anatomy sub…

Glia to neuron ratio in the posterior aspect of the human spinal cord at thoracic segments relevant to spinal cord stimulation.

2019

Spinal cord stimulation (SCS) applied between T8 and T11 segments has been shown to be effective for the treatment of chronic pain of the lower back and limbs. However, the mechanism of the analgesic effect at these medullary levels remains unclear. Numerous studies relate glial cells with development and maintenance of chronic neuropathic pain. Glial cells are electrically excitable, which makes them a potential therapeutic target using SCS. The aim of this study is to report glia to neuron ratio in thoracic segments relevant to SCS, as well as to characterize the glia cell population at these levels. Dissections from gray and white matter of posterior spinal cord segments (T8, T9, interse…

Effects of exercise frequency and training volume on bone changes following a multi-component exercise intervention in middle aged and older men: Sec…

2021

Progressive resistance training (PRT) combined with weight-bearing impact exercise are recommended to optimize bone health, but the optimal frequency and dose of training remains uncertain. This study, which is a secondary analysis of an 18-month intervention in men aged 50–79 years, examined the association between exercise frequency and the volume of training with changes in DXA and QCT-derived femoral neck (FN) and lumbar spine (LS) bone outcomes, respectively. Men were allocated to either thrice-weekly PRT plus impact exercise training (n = 87) or a non-exercising (n = 85) group. Average weekly exercise frequency (ExFreq) and training volume per session [PRT volume (weight lifted, kg), …

Analysis of the relationship between the double transverse foramen and the possibility of developing clinical symptoms after whiplash

2017

Introduction: Currently there is no information about the possibility of developing clinical symptoms after whiplash in double transverse foramen subjects. Our aim was to test whether subjects with double transverse foramen have an increased risk of presenting with acute headache, dizziness, vertebral artery dissection, and vomiting after whiplash. Methods: We recorded the absence/presence of double transverse foramen, and the absence/presence of neck pain, acute headache, dizziness, vertebral artery dissection, and vomiting in 85 patients who had suffered whiplash injuries in car rear-end impacts in road traffic accidents. We used the odds ratio test to determine whether double transverse …

Calcified Spinal Meningioma: A Lurking Danger

2017

Tumors of the spine with an intradural location have an incidence ranging from 3 to 10 per 100,000 persons per year, and intradural extramedullary tumors account for two thirds of all intraspinal neoplasms. Among these, spinal meningiomas account for 25%–46% of all spinal cord tumors. They develop from the arachnoid cells that differentiate from neural crest cells and, like cerebral meningioma, they have a slow-growing behavior. Although spinal meningiomas are not uncommon, calcified spinal meningioma is rare in spinal location. Calcified meningioma manifests with extensive matrix and tends to infiltrate the surrounding structures. It exhibits a growth pattern limited by an incompletely dev…

Trabecular trajectory in the articular processes of the human fourth cervical vertebra

2001

The articular processes (AP) of the neural arch have been implicated in weight transmission through the cervical spine. To analyse the mechanism of weight transmission in the AP, we studied the direction of forces within it, in particular, the pattern of trabecular trajectories. Twenty-two AP from C4 vertebrae were studied in anatomical sections, and corresponding photoelastic models from selected sections were constructed and analysed. Anatomical and photoelastic findings show the subarticular spongiosa of the superior articular process (SAP) to be orthogonally arranged with vertical and oblique trabeculae in the direction of compressive forces and additional trabeculae always oriented per…
