There are many problems facing the neurosurgeon when separating craniopagus twins. The condition is rare, with an incidence of 1 in 2.5 million births. As such there is a paucity of information in the literature regarding strategies for separation. ⋯ The aim of this article is to discuss the preoperative work-up, technical details of surgery, postoperative care and lessons learned with respect to the separation of craniopagus twins.

Baseline and 12-month follow-up data from a prospective controlled study on patients treated with SCS for neuropathic limb pain (NLP) are analyzed critically. The outcome on pain, use of medication, and quality of life are reported and compared with the literature. Patients enrolled from April 1999 to December 2001 were part of a quality system study by the Dutch Working Group on Neuromodulation. ⋯ The difference between baseline and 12-m follow-up is statistically significant for all measures. We conclude that the outcome measures indicate that SCS significantly reduces pain and enhances quality of life in patients having NLP not responding to other adjuvant therapy. Recommendations are proposed to make studies more comparable.

Use of stereotactic PET images in dosimetry planning of radiosurgery for brain tumors: clinical experience and proposed classification.
We developed a technique that allows the routine integration of PET in stereotactic neurosurgery, including radiosurgery. We report our clinical experience with the combined use of metabolic (i.e., PET) and anatomic (i.e., MRI and CT) images for the radiosurgical treatment of brain tumors. We propose a classification describing the relative role of the information provided by PET in this multimodality image-guided approach. ⋯ The integration of PET in radiosurgery provides additional information that opens new perspectives for the optimization of the treatment of brain tumors.
