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.

Complement inhibition attenuates brain edema and neurological deficits induced by thrombin.
The present study examined whether thrombin activates the complement cascade in the brain and whether N-acetylheparin, an inhibitor of complement activation, attenuates brain injury induced by thrombin. There were three sets of studies. In the first set, rats had an intracerebral infusion of either five-unit thrombin or a needle insertion. ⋯ Behavior was also significantly improved by N-acetylheparin (P < 0.05). In conclusion, thrombin-induced edema formation and neurological deficits were both reduced by N-acetylheparin. This suggests that inhibition may be a novel treatment for the thrombin-induced brain injury that occurs in intracerebral hemorrhage.

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.

Multicenter Study Clinical Trial Controlled Clinical TrialQuality management in traumatic brain injury (TBI) lessons from the prospective study in 6.800 patients after acute TBI in respect of neurorehabilitation.
Preliminary results on epidemiology, acute hospital care, and neurorehabilitation of TBI are presented of the first ever prospective controlled German study to analyse the use of regional structures and quality management as provided by the German social healthcare system. The sum of inhabitants in Hannover and Münster area was 2,114 million. Within an area of 100 kilometres diameter each. 6.783 acute TBI (58% male) were admitted for acute treatment from March 2000 to 2001. ⋯ The management of frequent complications in 148 patients (=57%) and the high number of one or more different consultations (n = 196) confirmed the author's concept for early neurosurgical rehabilitation in TBI when rehabilitation centres were compared regarding GCS and GOS: Early GOS 1 = 4%; GOS 2 = 2,7%, GOS 3 = 37,3%, GOS 4 = 26,7%, GOS 5 = 29,3%, final GOS scores were 1 = 1,2%, 2 = 1,7%, 3 = 21,8%, 4 = 36,2%, and 5 = 39,1% of all patients at the end of rehabilitation. Mean duration for both "B" and "C" was 41 days compared to 80 days for "D" and "E". An assessment of both GCS and GOS was insufficient.
