Endoscopic carpal tunnel release surgery: retrospective study of 390 consecutive cases.
Endoscopic carpal tunnel release (ECTR) surgery was developed by Okutsu and Chow in 1989. Many reports indicated that the endoscopic technique reduces postoperative morbidity with minimal incision, minimal pain and scarring, a shortened recovery period and high level of patient satisfaction. To evaluate these reports, a retrospective study was conducted with 390 procedures of two-portal Chow technique for idiopathic carpal tunnel syndrome. ⋯ The mean DML and SVC values at final follow-up were 3.8 msec and 42.3 m/s, respectively. In conclusion, ECTR can be used in the carpal tunnel syndrome and is a reliable alternative to the open procedure with excellent self-report of patient satisfaction. Reduced recovery period with minimal tissue violation and incisional pain can be expected.

The term internal neurolysis means removal of fibrotic tissue inside a nerve trunk. Unfortunately the term was used for procedures with complete isolation of fascicles with all consequences like damage of links between the fascicle and impairment of blood supply. The conclusion based on some negative experiences that all surgery within a nerve trunk has to be avoided cannot be accepted. ⋯ It stops immediately if this aim is achieved or continues with resection and reconstruction if an irreparable damage is present. It is better to use terms that describe exactly what was done and abandon the ill-defined term "internal neurolysis". Fibrosis of the paraneurium remains outside the epineurium but causes the same consequences as fibrosis of the epineurium.

Survey of traumatic brain injury management in European Brain-IT centres year 2001.
The aim of this study was to obtain basic knowledge about the current local conditions and neurointensive care of traumatic brain injury (TBI) in the new multi-centre collaborative BrainIT group. ⋯ There seemed to be an agreement on neurointensive care policies within the BrainIT group. The suggested order of treatment was generally in accordance with published guidelines although the suggested order and combinations of different treatments varied. Variation of treatment within the range of prescribed standards provides optimal conditions for an interesting future analysis of treatment and monitoring data in reality using the BrainIT database.

An open collaborative international network has been established which aims to improve inter-centre standards for collection of high-resolution, neurointensive care data on patients with traumatic brain injury. The group is also working towards the creation of an open access, detailed and validated database that will be useful for hypothesis generation. In Part A, we describe the underlying concept of the group and it's aims and in Part B we describe the current status of the groups development. ⋯ The BrainIT network provides a more standardised and higher resolution data collection mechanism for research groups, organisations and the device industry to conduct multicentre trials of new health care technology in patients with traumatic brain injury.

Management of ruptured aneurysms combined with coexisting aneurysms.
In patients suffering from subarachnoid haemorrhage (SAH) and presenting with multiple intracranial aneurysms (MIA) two questions have to be decided on: 1st when is the ideal moment to eliminate the ruptured aneurysm and 2nd when to treat the coexisting aneurysms. In our series we retrospectively analysed 124 SAH-patients presenting with a total of 323 aneurysms. In 57 patients the ruptured aneurysm and all coexisting aneurysms were clipped during the first operation, whereas in 9 patients only some of the coexisting aneurysms (group-A; age in median 55 years) were clipped besides the ruptured one. ⋯ Six to 12 months after the initial SAH, 78% of the cases in both groups reached a Glasgow Outcome Score of 4 or 5. Even if in patients with coexisting unruptured intracranial aneurysms the elimination of each and every aneurysm is recommended, the advantages of an unstaged procedure versus the additional strain caused by the prolongation of the procedure, e.g. approach over the midline, 2 or more craniotomies, and the risk of additional ischemic damage to the brain, caused by increased manipulation of cerebral arteries and brain tissue, have to be carefully considered. This is of special importance in dealing with patients in higher Hunt and Hess grades.
