Case ReportsSurgical treatment of spinal intradural carcinoma metastases.
Intradural metastases of nonneurogenic origin represent an extremely rare manifestation of systemic cancer. The respective literature is very scarce. ⋯ Intradural metastases are associated with limited survival time. Accordingly, the aim of surgery is strictly palliative. The majority of patients benefit with respect to neurological deficit/pain (67%) independent of the extent of resection. Thus, decompressive surgery is recommended to increase the quality of life.

Clinical TrialIntravenous and oral levetiracetam in patients with a suspected primary brain tumor and symptomatic seizures undergoing neurosurgery: the HELLO trial.
Levetiracetam (LEV) is a newer anticonvulsant with a favorable safety profile. There seem to be no relevant drug interactions, and an intravenous formulation is available. Therefore, LEV might be a suitable drug for the perioperative anticonvulsive therapy of patients with suspected brain tumors undergoing neurosurgery. ⋯ Our data show the feasibility and safety of oral and intravenous LEV in the perioperative treatment of tumor-related seizures. Although this was a single arm study, the efficacy of LEV appears promising. Considering the side effects and interactions of other anticonvulsants, LEV seems to be a favorable option in the perioperative treatment of brain tumor-related seizures.

Comparative StudyCement leakage as a possible complication of balloon kyphoplasty--is there a difference between osteoporotic compression fractures (AO type A1) and incomplete burst fractures (AO type A3.1)?
Besides the treatment of osteoporotic vertebral compression fractures of AO type A1, balloon kyphoplasty (BKP) is seen as a therapeutic option even in the treatment of incomplete osteoporotic burst fractures (AO type A3.1). However, due to involvement of the posterior vertebral body wall, the risk of cement leakages is considered to be higher. This study focuses on the frequency and pattern of cement leakages in AO type A3.1 fractures compared with osteoporotic compression fractures (AO type A1). ⋯ Cement leakages remain a problem in BKP. Although there was no significant difference between AO type A3.1 and all A1 fractures, subgroup analysis revealed a statistically significant higher risk of cement extrusions in A3.1 compared to A1.1 fractures. None of the affected patients showed new neurological deficits due to cement extravasations. Still, balloon kyphoplasty can be considered a safe procedure, even in the treatment of painful osteoporotic vertebral fractures of AO type A3.1.

Pregnancy and childbirth after microsurgery for lumbar disc herniation.
The influence of previous lumbar discectomy on pregnancy and childbirth has not been extensively studied. This study reports the course of pregnancies after lumbar discectomy. ⋯ The incidence of radicular pain during pregnancy after microsurgical discectomy for lumbar disc herniation was 18%. The incidence and prevalence of LBP are among the highest reported in the literature. The incidence of low back pain and radiculopathy signs does not change significantly with subsequent pregnancies. The operation rate for recurrent lumbar disc herniation or adjacent level disease after pregnancy seems not to be higher than the overall rate reported in the literature.

Thoracolumbar extradural arachnoid cysts: a study of 14 consecutive cases.
To investigate characteristic clinical and radiological features of extradural arachnoid cysts (EDACs) in the thoracolumbar region, a retrospective review of medical records and imaging studies was performed. EDACs are well known but relatively rare lesions in the thoracolumbar spinal canal. The most common site is the lower thoracic spine, and it may cause neurological symptoms by compressing the spinal cord or nerve root. In this study, the pathogenesis, symptomatology, diagnostic approach, and surgical management of EDACs will be discussed. ⋯ Thoracolumbar EDAC patients presented paraparesis and leg pain. Complete excision and closing the communicating point with the subarachnoid space were the choices of treatment, and the outcomes were favorable.
