[Assessment of Occupational Problems in Neurological Rehabilitation]. / Assessment beruflicher Problemlagen in der Neurorehabilitation.

Introduction: The so-called Würzburg Screening (WS) is recommended for assessing occupational problems among rehabilitation patients. However, it is unclear whether it can be used in neurological rehabilitation. Data of the WS as well as of a medical opinion of occupational problems (both assessed at the beginning of rehabilitation) was compared with prognoses of occupation at the end of rehabilitation. Methods: Data of 347 neurological post-acute rehabilitation patients were analyzed. Data of the WS as well as of a medical opinion of occupational problems (both assessed at the beginning of rehabilitation) was compared with prognoses of occupation at the end of rehabilitation. Results: The sensitivity of the WS to predict poor occupational outcome was 61.5 % while its specificity was 59.4 %. When combined with medical opinion, its sensitivity was higher (75 %) with a specificity of only 50.9 %. Regarding the prediction of further need for rehabilitation, the WS had a sensitivity of 56.3 % and specificity 76.4 %. Combined with the medical assessment, the sensitivity increased to 76.5 %, whereas the specificity was slightly lower with 76,1 %. Conclusion: Neither the WS alone nor the combination with a medical assessment allows valid prognoses of occupational problems and further rehabilitation needs at the beginning of rehabilitation. This suggests that the validity of the WS, which has been demonstrated for other indications, does not simply apply to neurological rehabilitation. Further studies are necessary to determine the validity of this scale.

[Occupational rehabilitation of neurological patients - long-term outcome data]. / Berufliche Teilhabe von neurologischen Rehabilitanden - Langzeitergebnisse eines medizinisch-beruflichen Rehabilitationszentrums (Phase II).

Occupational rehabilitation in Germany is done in specialized centres (so-called "Phase II" centres). In the present study, long-term outcome data of 237 neurological rehabilitation patients (mean age 38.3 years) were analyzed. Most of the patients had suffered brain injuries. The examination took place some 7 years after the end of occupational rehabilitation and approximately 10 years after the injury. About 60% of patients returned to work (35% worked, 9.3% were seeking a job, 13.5% underwent training). Positive predictors for return to work were lower age and high educational level. The results from this study suggest that occupational rehabilitation is effective. Controlled and multi-centre studies should be carried out.

Quality of life after liver transplantation.

Quality of life (QoL) is an outcome criterion of increasing importance after orthotopic liver transplantation (OLT). The background of this development is the dramatic improvement in patient survival rates over the past two decades combined with the question of the quality of this survival. Among 339 OLT performed in Kiel since 1987, 123 recipients (70 males, 53 females) of mean age 56.7 +/- 13.1 years who underwent transplantation between August 1992 and June 2007 were subjected to European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) C30 plus a liver transplant specific module to analyze QoL. In addition, we included 40 patients listed for OLT in the univariate and multivariate analyses performed using SPSS13.0. A cohort of healthy individuals served as the control group. QoL (global health) among liver recipients was reduced compared with the control group and improved compared with patients on the waiting list. Comparison of the underlying liver diseases showed a comparable QoL between postalcoholic cirrhosis and cholestatic liver diseases. Retransplantation was accompanied by a significant loss of QoL. Cyclosporine-treated recipients displayed a better QoL compared with those treated with tacrolimus. After establishing a system of continuous, systematic QoL assessment, we combined these results with survival outcomes. Further research must focus on advanced statistical methodology that combines these 2 major outcome parameters (QoL and survival). Furthermore, the influence of medical parameters, such of co-morbidity or immunosuppression, needs to be further established with reference to QoL.

Outpatient treatment of severe peripheral ischemia with intravenous intermittent low-dose iloprost. An open pilot study.

BACKGROUND: Iloprost given in a standard dose regimen (0.5-2 ng/kg/min for 6 hours daily over 21-28 days) has proven to be effective and safe in hospitalized patients with critical limb ischemia. Major drawbacks of the standard regimen are the high frequency of side effects, the long duration of the daily infusion, and a hospital stay of 3 to 4 weeks. Recently, the efficacy of low doses of iloprost (25 mg/day) was demonstrated. This open pilot study was undertaken to identify a more practical and cost-effective regimen with less side effects. The feasibility, efficacy and safety of an individually adapted, intermittently applied low-dose iloprost regimen in an outpatient setting were evaluated. METHODS: Twenty-seven patients with severe peripheral ischemia in the limbs or part of the limb due to various etiologies, who were eligible for outpatient treatment, were enrolled into the study. The infusion of iloprost (50 microg in 250 ml 0.9% saline) was started at 0.5 ng/kg BW/min and titrated to the individual optimum dose, which was defined as the maximum dose at which the patient felt entirely comfortable. The frequency of the iloprost infusions and the duration of the treatment were individually determined in each patient according to the severity of the clinical condition. Outcome endpoints were the response rates achieved by day 28, defined as substantial relief from rest pain and evidence of ulcer healing. The patients were followed up for a minimum of 6 months. RESULTS: A total of 27 patients (15 male, 12 female, mean age 65 years) were treated. Twenty-four patients received daily infusions with a break at weekends (5 times/week); 3 patients were treated every second day (3 times a week). The mean daily iloprost dose actually given was 20+/-5 microg, the mean duration of treatment was 3.6+/-0.8 weeks, i.e. a mean of 17+/-4 infusions were administered. Six patients with one-vessel run-off underwent percutaneous transluminal angioplasty (PTA) of their single calf vessel. Twenty-six patients showed clinical improvement by day 28; excluding those who had had PTA, the response rate to iloprost was 74% (20/27). No patient required admission to hospital while receiving outpatient treatment; no side effects occurred after adjustment to the optimum dose. At long-term follow-up (11+/-3 months), 76% of patients were alive and had a viable limb. CONCLUSIONS: In a limited number of patients with severe peripheral ischemia of various etiologies, long-term outpatient treatment with an individually adapted low-dose iloprost regimen was feasible and safe. Our data suggest that flexible treatment modalities might be as effective as rigid standard treatment regimens, the former being more advantageous in terms of greater practicability and cost-effectiveness due to outpatient management. Further studies are needed to confirm the efficacy of this individually adapted, low-dose outpatient iloprost treatment regimen in a larger number of patients.

[Left ventricular arrhythmogenic dysplasia]. / Linksventrikuläre arrhythmogene Dysplasie.

The present rare case study of left ventricular dysplasia attempts to improve understanding of the clinical picture of arrhythmogenic right ventricular dysplasia (ARVD), based on additional facts concerning this clinical picture which has been increasingly diagnosed over the last few years in the investigation of sudden death in adolescents.
