Data on survival with mucosal melanoma and on prognostic factors of are scarce. It is still unclear if the disease course allows for mucosal melanoma to be treated as primary cutaneous melanoma or if differences in overall survival patterns require adapted therapeutic approaches. Furthermore, this investigation is the first to present 10-year survival rates for mucosal melanomas of different anatomical localizations. 116 cases from Sep 10 1984 until Feb 15 2011 retrieved from the Comprehensive Cancer Center and of the Central Register of the German Dermatologic Society databases in Tübingen were included in our analysis. We recorded anatomical location and tumor thickness, and estimated overall survival at 2, 5 and 10 years and the mean overall survival time. Survival times were analyzed with the Kaplan-Meier method. The log-rank test was used to compare survival times by localizations and by T-stages. We found a median overall survival time of 80.9 months, with an overall 2-year survival of 71.7%, 5-year survival of 55.8% and 10-year survival of 38.3%. The 10-year survival rates for patients with T1, T2, T3 or T4 stage tumors were 100.0%, 77.9%, 66.3% and 10.6% respectively. 10-year survival of patients with melanomas of the vulva was 64.5% in comparison to 22.3% of patients with non-vulva mucosal melanomas. Survival times differed significantly between patients with melanomas of the vulva compared to the rest (p = 0.0006). It also depends on T-stage at the time of diagnosis (p < 0.0001).

Neuromuscular disorders (NMD) are chronic devastating diseases. The aim of this multicenter cross-sectional study was to evaluate the socioeconomic impact of three NMDs in Germany. Patients ( n  = 107) with amyotrophic lateral sclerosis (ALS), myasthenia gravis (MG) or facioscapulohumeral muscular dystrophy (FSHD) were recruited consecutively in seven centers in Germany. The health-economic data were collected using a “bottom-up” approach consisting of comprehensive questionnaires and patient diaries. Costs were evaluated from the societal perspective in 2009 Euros (EUR). Total annual costs from the societal perspective were EUR 36,380 (95% CI 27,090–47,970) per patient in ALS, EUR 26,240 (95% CI 17,770–37,940) in FSHD and EUR 14,950 (95% CI 10,470–21,730) in MG. The main components of costs were the expenditures of health insurance and the loss of productivity of patients and their caregivers. The following independent cost-driving factors were identified: disease severity, assistance in activities of daily living (ADL), dementia and younger age in ALS, disease severity in FSHD and assistance in ADL, disease severity and assistance in ADL in MG. The socioeconomic burden of NMDs in Germany is considerable. Further studies evaluating both the health-economic and clinical effects of NMD treatment as well as disease management programs and benchmarking activities are necessary.

Neuromuscular disorders are rare diseases with a chronic and debilitating course. Unfortunately, data on the health-related quality of life (HRQoL) in neuromuscular diseases are limited. The objective of this multicentre cross-sectional study was to compare the HRQoL in patients with amyotrophic lateral sclerosis (ALS), facioscapulohumeral muscular dystrophy (FSHD) and myasthenia gravis (MG) and to identify the determinants of the HRQoL in these diseases. We recruited 91 consecutive outpatients with ALS ( n  = 37), FSHD ( n  = 17) or MG ( n  = 37) in seven specialized German health centres. The HRQoL was determined using the 36-Item Short Form Health Survey (SF-36) and the EuroQol (EQ-5D). Independent predictors of the HRQoL were identified using multiple regression analysis. The HRQoL in all domains of the SF-36, except for bodily pain, was significantly reduced. The domains related to physical health (physical functioning, physical role) were most affected. The EQ-5D-index score was most reduced in ALS (0.54) and least reduced in MG (0.89). Independent predictors of a reduced HRQoL were disease severity and depression in ALS, and disease severity, depression, older age and increased body-mass index in MG. The patterns of HRQoL-impairment in neuromuscular disorders share some common features, such as a more pronounced reduction in the HRQoL related to physical health, but there are a number of disease-specific features that should be considered in outcomes of clinical trials and treatment guidelines. In addition to the treatment of motor symptoms, greater attention should be paid to the treatment of depression, which was found to be among the independent predictors of the HRQoL in ALS and MG.

The optimal treatment for patients with asymptomatic carotid artery stenosis is under debate. Since best medical treatment (BMT) has improved over time, the benefit of carotid endarterectomy (CEA) or carotid artery stenting (CAS) is unclear. Randomised data comparing the effect of CEA and CAS versus BMT alone are absent. We aimed to directly compare CEA plus BMT with CAS plus BMT and both with BMT only. SPACE-2 was a multicentre, randomised, controlled trial at 36 study centres in Austria, Germany, and Switzerland. We enrolled participants aged 50–85 years with asymptomatic carotid artery stenosis at the distal common carotid artery or the extracranial internal carotid artery of at least 70%, according to European Carotid Surgery Trial criteria. Initially designed as a three-arm trial including one group for BMT alone (with a randomised allocation ratio of 2·9:2·9:1), the SPACE-2 study design was amended (due to slow recruitment) to become two substudies with two arms each comparing CEA plus BMT with BMT alone (SPACE-2a) and CAS plus BMT with BMT alone (SPACE-2b); in each case in a 1:1 randomisation. Participants and clinicians were not masked to allocation. The primary efficacy endpoint was the cumulative incidence of any stroke or death from any cause within 30 days or any ipsilateral ischaemic stroke within 5 years. The primary safety endpoint was any stroke or death from any cause within 30 days after CEA or CAS. The primary analysis was by intention-to treat, which included all randomly assigned patients in SPACE-2, SPACE-2a, and SPACE-2b, analysed using meta-analysis of individual patient data. We did two-step hierarchical testing to first show superiority of CEA and CAS to BMT alone then to assess non-inferiority of CAS to CEA. Originally, we planned to recruit 3640 patients; however, the study had to be stopped prematurely due to insufficient recruitment. This report presents the primary analysis at 5-year follow-up. This trial is registered with ISRCTN, number ISRCTN78592017. 513 patients across SPACE-2, SPACE-2a, and SPACE-2b were recruited and surveyed between July 9, 2009, and Dec 12, 2019, of whom 203 (40%) were allocated to CEA plus BMT, 197 (38%) to CAS plus BMT, and 113 (22%) to BMT alone. Median follow-up was 59·9 months (IQR 46·6–60·0). The cumulative incidence of any stroke or death from any cause within 30 days or any ipsilateral ischaemic stroke within 5 years (primary efficacy endpoint) was 2·5% (95% CI 1·0–5·8) with CEA plus BMT, 4·4% (2·2–8·6) with CAS plus BMT, and 3·1% (1·0–9·4) with BMT alone. Cox proportional-hazard testing showed no difference in risk for the primary efficacy endpoint for CEA plus BMT versus BMT alone (hazard ratio [HR] 0·93, 95% CI 0·22–3·91; p=0·93) or for CAS plus BMT versus BMT alone (1·55, 0·41–5·85; p=0·52). Superiority of CEA or CAS to BMT was not shown, therefore non-inferiority testing was not done. In both the CEA group and the CAS group, five strokes and no deaths occurred in the 30-day period after the procedure. During the 5-year follow-up period, three ipsilateral strokes occurred in both the CAS plus BMT and BMT alone group, with none in the CEA plus BMT group. CEA plus BMT or CAS plus BMT were not found to be superior to BMT alone regarding risk of any stroke or death within 30 days or ipsilateral stroke during the 5-year observation period. Because of the small sample size, results should be interpreted with caution. German Federal Ministry of Education and Research (BMBF) and German Research Foundation (DFG).

Objective Suspicious incidental gastrointestinal FDG uptake during positron-emission tomography/computed tomography (PET/CT) examinations can be caused by different diseases, including malignancies. However, differentiation with PET alone is difficult. The aim of this study was to investigate the potential of PET alone, contrast-enhanced CT (ceCT), and low-dose CT (ldCT) in routine PET/CT protocols for differentiation of incidental gastrointestinal lesions. Materials and Methods Sixty patients with incidental gastrointestinal lesions who underwent a routine PET/CT protocol with ldCT and ceCT were retrospectively analysed. The PET lesions were evaluated regarding their FDG uptake patterns and the standard uptake value. The anatomical correlates in both CT protocols were compared in regard to the correct lesion classification with the reference standard endoscopy. Results Sixty-two lesions were found in 60 patients (17 malignant, 10 premalignant, 5 benign, 13 inflammatory, 17 physiological). The differentiation of the FDG uptake patterns did not enable reliable lesion classification. The positive predictive value for pathology was 0.81 for ceCT in PET/CT and 0.70 for ldCT. Malignancies were detected in 100% of the patients by ceCT vs. 29.4% by ldCT. The false negative rate of ceCT for all pathologies was 31.1%, vs. 68.9% for ldCT. False positive results (17/62) could not be excluded sufficiently by either CT protocol. Conclusion PET/ceCT protocols provide additional benefit especially in detecting gastrointestinal malignancies as a cause of suspicious incidental gastrointestinal FDG uptake. However, since follow-up endoscopy cannot be forgone due to the considerable false negative rate even with ceCT, the addition of ceCT to a routine PET/ldCT protocol cannot be recommended for this purpose.

Neurological involvement is a common feature of the antiphospholipid syndrome (APS). A variety of thrombotic and non-thrombotic manifestations may accompany the presence of antiphospholipid antibodies (aPL). We retrospectively reviewed the prevalence of aPL in a cohort of over 350 unselected patients from a neurological clinic and studied the neurological manifestations of APS. We found that within this cohort the prevalence of aPL was about 15%. Most of the patients with aPL suffered from strokes and transient ischemic attacks (TIA). One patient died from spinal infarction. Non-thrombotic manifestations also occurred in 40% of these patients, such as multiple sclerosis, chorea, seizures or cerebral malignancies. No significant correlations of the titres or different types of aPL and the type of the neurological symptoms could be found. In comparison to age and sex matched patients of the cohort where the presence of aPL could be excluded, the occurrence of non-thrombotic manifestations was significantly more frequent and varied in the group of patients with aPL. The higher incidence of stroke in the non-APS group could be explained by the significantly higher presence of other laboratory risk factors, mainly hypercholesterinemia. This investigation indicates that aPL may play an important role in the etiology of various neurological syndromes.

High-sensitive C-reactive protein (hs-CRP) is a marker of inflammation which has been shown in several prospective studies to independently predict myocardial infarction, stroke and peripheral artery disease. Patients with antiphospholipid antibodies (aPL) are at increased risk of recurrent thromboembolic events, but the possibility of predicting this risk seems rather limited. Similarities were recently found between aPL and CRP in the pathology of thrombosis. The current study investigated the predictive role of hs-CRP in a cohort of patients with neurological manifestations. A follow-up investigation was done in a cohort of 55 aPL-positive patients with acute manifestations of neurological disease. hs-CRP levels were measured in all patients at enrolment and were compared to the patients’ condition after a median period of 32 months. Lupus anticoagulants were detected according to the Standardization of Lupus Anticoagulants (SSC) of the ISTH. Anticardiolipin tests were performed by a β2-glycoprotein I-dependent enzyme-linked immunsorbent assay (Pharmacia ELISA). hs-CRP was measured by latex-enhanced turbidometry (dimension RXL, Dade Behring). Cerebral infarctions and transient ischemic attacks were the most frequent cerebral events. In patients with aPL, elevated levels of hs-CRP were closely associated with an increased rate of recurrent or residual symptoms (OR, 12.5; 95% CI, 3.72–41.94) and were not related to other risk factors, except smoking ( p < 0.05 ). The rate at which a given patient's condition deteriorated was also related to the level of hs-CRP. In patients with antiphospholipid syndrome (APS), elevated levels of hs-CRP may identify a group of patients which is at high risk of recurrent or residual neurological symptoms and which may benefit from more careful follow-up and from antithrombotic therapy.

Hysteria was the Sphinx of nervous disorders. In ancient times the cause of hysteria was supposed to be sited in the womb. However the French Neurologist Jean-Martin Charcot favoured the ovaries as the site of the origin of hysteria, and he recommended the therapeutic compression of the ovaries in order to terminate hysterical fits. To this end, the treatment of hysteria in women was carried out by the surgical removal of one ovary. This surgical intervention was not without risk in the 19th century, but more to the point it did not help the patients. Most German Neurologists doubted this “hysteric ovary” theory, but it was not until after 1901 that Steinhausen was able to prove by statistical analysis, that the “hysteric” ovary did not exist at all. Statistical data analysis also helped to support the connection between Syphilis and Tabes dorsalis, which usually became clinically manifest several years after infection. In those days neither cerebrospinal fluid analysis nor serology were available. Apart from several nonspecific suspected causes of Tabes - it was the use of the newly invented sewing machine that came under suspicion as the trigger of Tabes dorsalis.
