The presence of endogenous acids from bacteria acting on a suitable substrate combined with sources of exogenous biocorrosives such as exogenous acids and proteolytic enzymes in areas of stress concentration are hypothesized to lead to the development and progression of cervical and root caries (RC). Quantifying the effects of each of the mechanisms (stress and biocorrosion) is a daunting task to investigate since so many factors are involved at various times in the etiology of noncarious cervical lesions (NCCLs), cervical caries (CC), and RC...

BACKGROUND: The cervical vestibular evoked myogenic potential (cVEMP) represents an inhibitory reflex of the saccule measured in the ipsilateral sternocleidomastoid muscle (SCM) in response to acoustic or vibrational stimulation. Since the cVEMP is a modulation of SCM electromyographic (EMG) activity, cVEMP amplitude is proportional to muscle EMG amplitude. We sought to evaluate muscle contraction influences on cVEMP peak-to-peak amplitudes (VEMPpp), normalized cVEMP amplitudes (VEMPn), and inhibition depth (VEMPid)...

We transplanted human olfactory bulb OECs (hOECs) mixed with collagen into a unilateral transection of four dorsal roots (C6-T1) in a rat model. By mixing with collagen, we could maximise the limited numbers of hOEC from an olfactory bulb biopsy and optimise cavity-filling. Cyclosporine was administered daily to prevent immune rejection. Forelimb proprioception was assessed weekly in a vertical climb task. Half of the rats receiving hOEC transplants showed some functional improvement ('responders') over six weeks of the study whilst the other half did not ('non-responders') and performed similarly to 'injured only' rats...

Invasive cervical resorption (ICR) is an aggressive and invasive form of external tooth resorption that commences in the cervical region which can be managed using either a nonsurgical, surgical or a combination of nonsurgical and surgical approach. The restoration of resorptive defects having a coronal and radicular extent can be challenging as a single material cannot be used to restore the entire defect. This case presented with Heithersay's Class 3 ICR lesion in tooth #12, which was managed initially using a surgical approach and restoration of ICR defect with a combination of resin modified glass ionomer cement, composite resin and mineral trioxide aggregate (MTA)...

BACKGROUND: Spinal epidural lipomatosis (SEL) is a rare pathologic growth of histologically normal unencapsulated adipose tissue in the epidural space. Although rare, SEL can compress the spinal cord or nerve roots causing myelopathy or radiculopathy. While SEL has been associated with long-term exposure to endogenous or exogenous steroids and obesity, idiopathic forms of SEL are much rarer. CASE REPORT: In this report, we present the first case of SEL isolated to the cervical region compressing the spinal cord in a healthy, non-obese, preadolescent patient...

Mineralization of bones and teeth is tightly regulated by levels of extracellular inorganic phosphate (Pi) and pyrophosphate (PPi). Three regulators that control pericellular concentrations of Pi and PPi include tissue-nonspecific alkaline phosphatase (TNAP), progressive ankylosis protein (ANK), and ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1). Inactivation of these factors results in mineralization disorders affecting teeth and their supporting structures. This study for the first time analyzed the effect of decreased PPi on dental development in individuals with generalized arterial calcification of infancy (GACI) due to loss-of-function mutations in the ENPP1 gene...
