Symptomatic ventral cervical cord compressions have been treated by anterior discectomy with fusion, anterior corpectomy and fusion, discectomy with an artificial disc, and minimally invasive techniques. There are complications associated with the fusion procedure, especially when a long segment fusion is undertaken. Partial removal of the vertebral body without fusion could help in avoiding fusion and its associated complications. We are describing the detailed surgical technique, indications, limitations, and early results of endoscopic partially corpectomy...

BACKGROUND: Air-conducted and skull-tap cervical vestibular evoked myogenic potentials (AC-cVEMP and Tap-cVEMP) have been shown to be very promising tools in clinical practice. They are noninvasive, easy to obtain and - importantly - they require little time and the cost of the instruments is low. OBJECTIVES: The aim of this study was to evaluate the usefulness of the combined use of ACand Tap-cVEMPs as a diagnostic tool for advanced assessment of vestibular schwannoma in determining tumor origin, and to investigate whether the results are helpful for a surgeon as an additional source of information about the tumor before surgery...

Recovery from serious neurological injury requires substantial rewiring of neural circuits. Precisely-timed electrical stimulation could be used to restore corrective feedback mechanisms and promote adaptive plasticity after neurological insult, such as spinal cord injury (SCI) or stroke. This study provides the first evidence that closed-loop vagus nerve stimulation (CLV) based on the synaptic eligibility trace leads to dramatic recovery from the most common forms of SCI. The addition of CLV to rehabilitation promoted substantially more recovery of forelimb function compared to rehabilitation alone following chronic unilateral or bilateral cervical SCI in a rat model...

We herein report anesthetic management during aortic valve replacement for aortic valve regurgitation in a patient with adult mucopolysaccharidosis type II (MPS type 2) (Hunter syndrome). This disorder is rare and related to the accumulation of a mucopolysaccharide in lysosomes. It affects various organs, including the airways, heart, and central nerves. In children with MPS type 2, the risk of airway obstruction during anesthesia/sedation is high, and the degree of difficulty increases with aging. The patient described herein was a 33-year-old male without mental retardation...

Cervical laminoplasty was initially described for the management of cervical myelopathy resulting from multilevel stenosis secondary to ossification of the posterior longitudinal ligament. The general concepts are preservation of the dorsal elements, preservation of segmental motion, and expansion of the spinal canal via laminar manipulation. No clear evidence suggests that laminoplasty is superior to either posterior laminectomy or anterior cervical diskectomy and fusion. However, laminoplasty has its own advantages, indications, and complications...

RATIONALE: Cervical open-door laminoplasty can enlarge the volume of the cervical vertebral canal and thus has become an effective and safe treatment for multilevel cervical disc herniation and cervical stenosis. Some post-surgery complications exist, such as reduction of cervical alignment and local kyphosis. However, aggravation of cervical disc herniation at the surgical level during short-term follow-up has not been discussed. Additionally, spontaneous disappearance of herniated disc pulposus is a common phenomenon in the lumbar region but is relatively rare in the cervical region...

The giant (>3 m) parasitic nematode Crassicauda magna infects kogiid whales, although only 3 studies to date have provided detailed descriptions of these worms, all based upon fragmented specimens. These fragments were found within the neck region of kogiids, an unusual anatomic site for this genus of parasites. C. magna is a species-specific parasite among kogiids, infecting only pygmy sperm whales Kogia breviceps, and with a primarily cervico-thoracic distribution. To date, however, the pattern of habitat use within the host and transmission path of this parasite remain unknown...

Background: The physiological sagittal spinal curvature represents a typical feature of good body posture in the sagittal plane. The cervical and the lumbar spine are curved anteriorly (lordosis), while the thoracic segment is curved posteriorly (kyphosis). The pelvis is inclined anteriorly, and the lower limbs' joints remain in a neutral position. However, there are many deviations from the optimal body alignment.The aim of this paper is to present the most common types of non-structural misalignments of the body posture in the sagittal plane...

A 40-year-old female presented with a skin rash, hepatosplenomegaly, hypothyroidism, IgG-λ monoclonal gammopathy, slightly elevated serum VEGF levels, and >1-year history of weakness in the posterior cervical muscles. Based on these symptoms and her clinical course, she was suspected of having POEMS syndrome. However, because there was no sign of peripheral neuropathy (PN), the criteria for the diagnosis of POEMS syndrome were not met. Consequently, she continued follow-up and was under close observation as an outpatient...

Disorders of sexual development are rare in non-human primates. We report a case of true hermaphroditism in a 19-year-old, nulliparous, female baboon (Papio spp.). At necropsy, the animal was obese with adequate muscle mass and hydration. Reproductive organs appeared normal with the exception of 2 firm nodular structures in the myometrium (1-1.5 cm diameter) and a thickened, dark endocervical mucosa. Histologically, both gonads were ovotestes and contained discrete areas of ovarian and testicular tissue. There were follicles in various stages of development surrounded by ovarian stroma...
