Post laminoplasty cervical kyphosis-Case report.

INTRODUCTION: Cervical kyphosis is a progressive cervical sagittal plane deformity that may cause a reduction in the ability to look horizontally, breathing and swallowing difficulties, sense of thoracic oppression and social isolation. Moreover, cervical kyphosis can cause myelopathy due to a direct compression by osteo-articular structures on the spinal cord or to a transitory ischaemic injury. The treatment of choice is surgery. The goals of surgery are: nervous structures decompression, cervical and global sagittal balance correction and vertebral stabilization and fusion. PRESENTATION OF CASE: In October 2008 a 35 years old woman underwent surgical removal of a cervical-bulbar ependymoma with C1-C5 laminectomy and a C2-C5 laminoplasty. Five months after surgery, the patient developed a kyphotic posture, with intense neck and scapular girdle pain. The patients had a flexible cervical kyphosis. Therefore, we decided to perform an anterior surgical approach. We performed a corpectomy C4-C5 in order to achieve the anterior decompression; we placed a titanium expansion mesh. DISCUSSION: Cervical kyphosis can be flexible or fixed. Some authors have reported the use of anterior surgery only for flexible cervical kyphosis as discectomy and corpectomy. This approach is useful for anterior column load sharing however it is not required for deformity correction. CONCLUSION: The anterior approach is a good surgical option in flexible cervical kyphosis. It is of primary importance the sagittal alignment of the cervical spine in order to decompress the nervous structures and to guarantee a long-term stability.

Spinal schwannomatosis in the absence of neurofibromatosis: A very rare condition.

Schwannomatosis is defined as an extremely rare tumors syndrome characterized by the presence of multiple schwannomas in the absence of typical signs of NF1 and NF2 syndromes. The genetic and molecular analysis performed on these tumors makes it possible to name schwannomatosis as distinct clinical and genetic syndrome. The treatment in the case of symptomatic lesions is surgical removal; if the lesions are asymptomatic it is better to perform serial MRI studies. Given the high incidence of developing additional lesions in patients with schwannomatosis, it remains imperative to perform serial brain and spinal cord MRI studies during follow-up. The differential diagnosis is important including clinical and radiological criteria plus molecular genetic analysis of tumor cells and lymphocyte DNA. We report a rare case of spinal schwannomatosis in which genetic analysis performed on surgical samples showed two different mutations in the cells of the two lesions.

Management of calcified thoracic disc herniation using ultrasonic bone curette SONO-PET®: technical description.

This paper describes the surgical management of a post-traumatic calcified thoracic disc herniation treated using ultrasonic bone curette SONO-PET®. The case described concerns a young man with a symptomatic calcified thoracic disc herniation, who underwent posterolateral approach and transversoarthropediculectomy. Patient underwent posterolateral approach with excellent postoperative results. Neurophysiological monitoring somato-sensory evoked potential (SSEP) and muscle motor evoked potentials (MMEP), inclination of 30° toward the unaffected side of the operating table, the use of Ultrasonic Bone-Curette SONO-PET® and proper reconstruction of the three floors of the back muscles allows the removal of the disc herniation safer and risk's free, and less invasive for the patient.

A possible role of ID-Migraine in the emergency department: study of an emergency department out-patient population.

Headache symptoms account for 1-3% of admissions to an emergency department (ED). Most patients affected by a primary headache (PH) have migraine, although they are often misdiagnosed as 'headache not otherwise specified'. We investigated the possibility of using ID-Migraine (ID-M) to improve migraine recognition in the ED setting. We planned a pilot study involving ED out-patients with a diagnosis of PH. Diagnoses of a blinded headache expert were subsequently matched with the ID-M results. We tested ID-M on 230 patients (199 PH, 31 secondary headaches). Considering only PH, ID-M exhibited a sensitivity of 0.94 and specificity of 0.83 with a positive predictive value (PPV) of 0.99. The ID-M is a simple migraine screener with high sensitivity, high specificity and high PPV, even in an ED-derived population. Methodical use of this tool in an ED setting may, once a secondary headache has been excluded, lead to rapid diagnosis of migraine.
