Intra-arterial thrombolysis in 100 patients with acute stroke due to middle cerebral artery occlusion

BACKGROUND AND PURPOSE: The purpose of this study was to evaluate the safety and efficacy of local intra-arterial thrombolysis (LIT) using urokinase in patients with acute stroke due to middle cerebral artery (MCA) occlusion. METHODS: We analyzed clinical and radiological findings and functional outcome 3 months after LIT with urokinase of 100 consecutive patients. To measure outcome, the modified Rankin scale (mRs) score was used. RESULTS: Angiography showed occlusion of the M1 segment of the MCA in 57 patients, of the M2 segment in 21, and of the M3 or M4 segment in 22. The median National Institutes of Health Stroke Scale (NIHSS) score at admission was 14, and, on average, 236 minutes elapsed from symptom onset to LIT. Forty-seven patients (47%) had an excellent outcome (mRs score 0 to 1), 21 (21%) a good outcome (mRs score 2), and 22 (22%) a poor outcome (mRs score 3 to 5). Ten patients (10%) died. Excellent or good outcome (mRs score < or =2) was seen in 59% of patients with M1 or M2 and 95% of those with M(3) or M(4) MCA occlusions. Recanalization as seen on angiography was complete (thrombolysis in myocardial infarction [TIMI] grade 3) in 20% of patients and partial (TIMI grade 2) in 56% of patients. Age <60 years (P<0.05), low NIHSS score at admission (P<0.00001), and vessel recanalization (P=0.0004) were independently associated with excellent or good outcome and diabetes with poor outcome (P=0.002). Symptomatic cerebral hemorrhage occurred in 7 patients (7%). CONCLUSIONS: LIT with urokinase that is administered by a single organized stroke team is safe and can be as efficacious as thrombolysis has been in large multicenter clinical trials.

Preserving middle lobe to improve lung function in non-small-cell lung cancer

When a lung tumor arises in segment 6, the close anatomical relationship to the middle lobe bronchus may make a lower bilobectomy necessary. Sleeve lobectomy may be an alternative. These procedures were compared retrospectively in 36 patients operated on between January 2005 and December 2006 with non-small-cell lung cancer (stage I-IIIB) of the right lower lobe. Sleeve lobectomy was performed in 21 patients and bilobectomy in 15 (41%). Preoperative lung function was comparable in both groups. Radical resection was achieved in 34/36 patients. Operation time was 121 min for sleeve lobectomy and 144 min for bilobectomy. Chest tubes were removed after 5 days in both groups. Postoperative lung function was better after sleeve lobectomy than bilobectomy (forced expiratory volume in 1st sec: 78% vs. 69%). Preservation of the middle lobe by sleeve lobectomy is feasible. There was no evidence that this resection was less radical, and complication rates were similar in both groups.

Stud.IP and ILIAS in an EU-Funded Project for the Middle East

In autumn 2005 InWEnt (Internationale Weiterbildung und Entwicklung/Capacity Building International gGmbH) on behalf of the EU invited to tender for three web based trainings (WBT). The precondition: either the open-source-platform Stud.IP or ILIAS should be used. The company data-quest decided not to offer the use of either Stud.IP or ILIAS, but both in combination - and won the contract. Several month later, the new learning environment with the combined powers of Stud.IP and ILIAS was ready to serve WBT-participants from all over the world. The following text describes the EU-Project "Efficient Management of Wastewater, its Treatment and Reuse in the Mediterranean Countries" (EMWater), the WBT concept and the experiences with the new Stud.IP-ILIAS-interface.
