BACKGROUND:Adrenocortical carcinoma (ACC) is a rare malignancy, and it was only in 2004 that the International Union Against Cancer (UICC) defined TNM criteria and published the first staging classification. However, to date, the prognostic value of the proposed classification has not been evaluated.METHODS:The German ACC Registry comprising 492 patients was searched for patients who were diagnosed between 1986 and 2007 with detailed information on primary diagnosis and a minimum follow‐up of 6 months. Patients were assigned to UICC tumor stage, and disease‐specific survival (DSS) was assessed. In addition, the contribution of potential risk factors for DSS was evaluated.RESULTS:In total, 416 patients with a mean follow‐up of 36 months met the inclusion criteria (stage I, n = 23 patients; stage II, n = 176 patients; stage III, n = 67 patients; stage IV, n = 150 patients). Kaplan‐Meier analysis revealed a stage‐dependent DSS. However, DSS in patients with stage II ACC did not differ significantly from DSS in patients with stage III ACC (hazard ratio, 1.38; 95% confidence interval, 0.89‐2.16). Furthermore, patients who had stage IV ACC without distant metastases had an improved DSS compared with patients who had metastatic disease (P = .004). An analysis of different potential risk factors for defining stage III ACC revealed important roles in DSS for tumor infiltration in surrounding tissue, venous tumor thrombus (VTT), and positive lymph nodes; whereas tumor invasion in adjacent organs carried a prognosis similar to that of infiltration in surrounding tissue only.CONCLUSIONS:The 2004 UICC staging classification for ACC has significant limitations. On the basis of the current analysis, a revised classification with superior prognostic accuracy is proposed (the European Network for the Study of Adrenal Tumors classification). In this system, stage III ACC is defined by the presence of positive lymph nodes, infiltration of surrounding tissue, or VTT; and stage IV ACC is restricted to patients with distant metastasis.

Summary:Purpose: To determine the incidence and casefatality rate of status epilepticus (SE) in adults in Hessen, Germany, we performed a prospective, population-based study from July 1997 through June 1999.Methods: All adult patients residing within the zip-code area 35 (area-35) with SE were included. Area-35 had 743.285 adult inhabitants, including 123.353 adult inhabitants of the primary service area of the University Hospital Marburg (PS-area). Patients were reported by 16 hospitals in the area and were prospectively identified and carefully reviewed within 5 days by one of the authors. Based on the crude annual incidence of SE and a rate of underascertainment of 10% determined for the PS-area, the corrected, age-adjusted incidence of SE in area 35, more representative of the population of Germany, was calculated.Results: The crude annual incidence in the PS-area was 15.8/ 100,000 [95% confidence interval (CI), 11.2-21.6]. The calculated, corrected, age-adjusted incidence of SE in area 35 was 17.1/100,000. It was higher for men compared with women (26.1 vs. 13.7) and for those aged 60 years and older (54.5 vs. 4.2/100,000, p < 0.0001). The etiology was mainly remote symptomatic due to cerebrovascular disease. Epilepsy was previously diagnosed in only 50% of the patients. The case-fatality rate was 9.3%.Conclusions: Based on our data, at least 14,000 patients would be affected by SE in Germany, associated with ∼1,300 deaths annually. The incidence of SE in Germany is similar to that found in the white United States population. Furthermore, this study confirms the higher incidence of SE in male patients and in the elderly population. This may be due to a higher incidence of cerebrovascular disease in these subpopulations.
Objective To determine the effectiveness of extracorporeal shock wave therapy compared with placebo in the treatment of chronic plantar fasciitis. Design Randomised, blinded, multicentre trial with parallel group design. Setting Nine hospitals and one outpatient clinic in Germany. Participants 272 patients with chronic plantar fasciitis recalcitrant to conservative therapy for at least six months: 135 patients were allocated extracorporeal shock wave therapy and 137 were allocated placebo. Main outcome measures Primary end point was the success rate 12 weeks after intervention based on the Roles and Maudsley score. Secondary end points encompassed subjective pain ratings and walking ability up to a year after the last intervention. Results The primary end point could be assessed in 94% (n=256) of patients. The success rate 12 weeks after intervention was 34% (n=43) in the extracorporeal shock wave therapy group and 30% (n=39) in the placebo group (95% confidence interval − 8.0% to 15.1%). No difference was found in the secondary end points. Few side effects were reported. Conclusions Extracorporeal shock wave therapy is ineffective in the treatment of chronic plantar fasciitis.
It is unclear whether focal epilepsies chronically influence the processing of cortex distant to the epileptogenic zone. Therefore, motor cortex excitability was analysed in patients with temporal and extratemporal epilepsies whose epileptogenic zones did not include the primary motor area. Single and paired-pulse transcranial magnetic stimulation (TMS) was applied to the primary motor cortex in 20 healthy controls and 23 patients with focal epilepsy (39.4 +/- 13.2 years; 12 left, 11 right; 14 temporal, nine extratemporal: six frontal, three parieto-occipital) ipsi- and contralateral to the epileptogenic zone. In all patients, the epileptogenic zone did not include the primary motor cortex. The resting motor threshold (RMT), the cortical silent period (CSP), the intracortical inhibition [ICI; combined interstimulus intervals (ISI) 2 and 3 ms] and the intracortical facilitation (ICF; combined ISI 10 and 15 ms) were determined. The measures obtained ipsilateral to the epileptogenic zone were compared with those elicited in contralateral hemispheres and, in exploratory analyses, with controls using non-parametric tests, including Hodges-Lehmann estimates of median differences (HLE) with 95% confidence intervals (CI). In the patient group, the CSP elicited in the ipsilateral motor cortex (median 162.3 ms) was shortened compared with the contralateral CSP (median 174.6 ms; HLE 15.9 ms; CI 6.2, 27.0 ms; P = 0.002). This interhemispheric difference was more pronounced in extratemporal epilepsies (HLE 23.4 ms; CI -3.2, 67.6 ms) compared with temporal epilepsies (HLE 14.3 ms; CI 4.7, 26.2 ms). Patients with parieto-occipital epilepsies showed the greatest interhemispheric differences in CSP (HLE 33.5 ms) and patients with mesial temporal epilepsies the smallest (HLE 9.9 ms). No significant differences were found between ipsi- and contralateral RMT, ICI or ICF. In analyses of subgroups, the CSP was shorter in epileptic hemispheres of patients with extratemporal epilepsies (141.4 ms) than in controls (173.4 ms; HLE 40.0 ms; CI 3.2, 83.4 ms; P = 0.029). ICF was increased in epileptic hemispheres of extratemporal epilepsies (147.6%) compared with temporal epilepsies (114.6%; HLE 33.0%; CI 4.1, 68.3%; P = 0.038). The results suggest that focal epilepsies influence chronically distant cortex, leading to decreased inhibition and increased facilitation in the ipsilateral motor cortex even when the epileptogenic zone is apart from it. This alteration may be due to synaptic reorganization and appears to be more pronounced in extratemporal and neocortical temporal than in mesial temporal epilepsies. This may have diagnostic implications.
