Diastatic skull fractures (DSFs) in children are difficult to detect in skull radiographs before they develop into growing skull fractures; therefore, little information is available on this topic. However, recent advances in 3-dimensional (3D) computed tomography (CT) imaging technology have enabled more accurate diagnoses of almost all forms of skull fracture. The present study was undertaken to document the clinical characteristics of DSFs in children and to determine whether 3D CT enhances diagnostic accuracy. ⋯ 3D CT was found to be markedly superior to skull radiography or 2D CT for detecting DSFs. This finding indicates that 3D CT should be used routinely rather than 2D CT for the assessment of pediatric head trauma.

Stereotactic radiosurgery (SRS) is a well-established treatment modality for cerebral arteriovenous malformations (AVMs). The main limiting factor in the radiosurgical treatment of AVMs is the volume of the nidus, with high-grade lesions often requiring combined treatment to reduce the SRS target volume. To overcome this limitation, we have been using a combined treatment approach consisting of endovascular embolization with Onyx followed by SRS. ⋯ The multimodality treatment of cerebral AVMs using embolization with Onyx followed by SRS is feasible and safe. The use of Onyx significantly reduced the SRS treatment target volume.

Comparative Study
Comparison of different sequences of MRI and Ultrasongram with Nerve Conduction Studies in peripheral neuropathies.
Peripheral neuropathies refer to a group of disorders in which there is damage to the nerves of the peripheral nervous system. Electrophysiologic studies are the main stay for the diagnosis of peripheral neuropathies. However, direct visualization of the nerves is possible with exact localization of site of disease with high-resolution ultrasonography (USG) and 3-Tesla magnetic resonance imaging (MRI) scanner, and newer magnetic resonance (MR) sequences. ⋯ USG is a sensitive technique to diagnose peripheral neuropathies and it should be used as a screening modality for focused MR to be performed later. Turbo spin echo T2W fast spin has the highest sensitivity to identify nerve disease and is comparable with nerve conduction studies. Among the newer sequences, diffusion tensor imaging should be performed to increase diagnostic confidence.

Comparative Study
Minimally invasive versus open surgery for lumbar synovial cysts.
Lumbar synovial cysts are relatively infrequent. Historically, these benign lesions have been treated with open excision, sometimes associated with fusion. The aim of this study is to compare minimally invasive surgery (MIS) with open surgery (OS) for the treatment of lumbar synovial cysts. ⋯ In this study, MIS for the treatment of lumbar synovial cysts appears to be more effective than OS in relieving radicular symptoms. Furthermore, MIS is better tolerated by patients and is potentially cost saving for the Health Service, due to the reduction in hospital stay and the reduced requirement for painkillers.

Non-small-cell lung cancer (NSCLC) is one of the most common primary tumor sites among patients with metastatic spinal cord compression (MSCC). This disorder is related to neurologic dysfunction and can reduce the quality of life, but the association between MSCC and death is unclear. The aim of this study was to analyze the impact of the occurrence of symptomatic MSCC on overall survival of patients with NSCLC. ⋯ MSCC is an important and independent predictor of NSCLC worse survival. This effect was not influenced by sociodemographic and clinical factors.
