Abstract
Inflammatory pituitary lesions account for 1.8% of all specimens from the German Pituitary Tumor Registry. They occure in 0.5% of the autoptical specimens and in 2.2% of the surgical cases. Women are significantly more often affected than men and are often younger when first diagnosed. In general, primary and secondary inflammation can be distinguished, with secondary types occurring more frequently (75.1%) than idiopathic inflammatory lesions (15.4%). In primary inflammation, the lymphocytic type is more common (88.5%) than the granulomatous type of hypophysitis (11.5%). The most common causes of secondary inflammation are Rathke's cleft cysts (48.6%), followed by tumors (17.4%) such as the craniopharyngioma (9.1%), adenoma (5.5%) or germinoma (2.0%). More causes are tumor-like lesions (7.1%) such as xanthogranuloma (3.5%) or Langerhans histiocytosis (3.5%), abscesses (5.5%), generalized infections (5.1%), spreaded inflammations (4.7%) and previous surgeries (4.0%). In 1.6% of all specimens the reason for the inflammation remains unclear. The described classification of hypophysitis is important for specific treatment planning after surgery.

Abstract
BACKGROUND Autopsies are a valuable tool for understanding disease, including COVID-19. MATERIALS AND METHODS The German Registry of COVID-19 Autopsies (DeRegCOVID), established in April 2020, serves as the electronic backbone of the National Autopsy Network (NATON), launched in early 2022 following DEFEAT PANDEMIcs. RESULTS The NATON consortium's interconnected, collaborative autopsy research is enabled by an unprecedented collaboration of 138 individuals at more than 35 German university and non-university autopsy centers through which pathology, neuropathology, and forensic medicine autopsy data including data on biomaterials are collected in DeRegCOVID and tissue-based research and methods development are conducted. More than 145 publications have now emerged from participating autopsy centers, highlighting various basic science and clinical aspects of COVID-19, such as thromboembolic events, organ tropism, SARS-CoV‑2 detection methods, and infectivity of SARS-CoV-2 at autopsy. CONCLUSIONS Participating centers have demonstrated the high value of autopsy and autopsy-derived data and biomaterials to modern medicine. The planned long-term continuation and further development of the registry and network, as well as the open and participatory design, will allow the involvement of all interested partners.

Abstract
Sporadic Alzheimer's disease (SAD) is the most common form of dementia, and cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most frequent hereditary ischemic small vessel disease of the brain. Relevant biomarkers or specific metabolic signatures could provide powerful tools to manage these diseases. Therefore, the main goal of this study was to compare the postmortem frontal cortex gray matter, white matter and cerebrospinal fluid (CSF) between a cognitively healthy group and CADASIL and SAD groups. We evaluated 352 individual lipids, belonging to 13 lipid classes/subclasses, using mass spectrometry, and the lipid profiles were subjected to multivariate analysis to discriminate between the dementia groups (CADASIL and SAD) and healthy controls. The main lipid molecular species showing greater discrimination by partial least squares-discriminant analysis (PLS-DA) and a higher significance multivariate correlation (sMC) index were as follows: phosphatidylserine (PS) PS(44:7) and lysophosphatidylethanolamine (LPE) LPE(18:2) in gray matter (GM); phosphatidylethanolamine (PE) PE(32:2) and phosphatidylcholine PC PC(44:6) in white matter (WM), and ether PE (ePE) ePE(38:2) and ether PC (ePC) ePC(34:3) in CSF. Common phospholipid molecular species were obtained in both dementias, such as PS(44:7) and lyso PC (LPC) LPC(22:5) in GM, PE(32:2) in WM and phosphatidic acid (PA) PA(38:5) and PC(42:7) in CFS. Our exploratory study suggests that phospholipids (PLs) involved in neurotransmission alteration, connectivity impairment and inflammation response in GM, WM and CSF are a transversal phenomenon affecting dementias such as CADASIL and SAD independent of the etiopathogenesis, thus providing a possible common prodromal phospholipidic biomarker of dementia.

Abstract
Abstract
BACKGROUND
Ketogenic diet (KD) and fasting have anticancer effects in tumor models, possibly due to a differential stress response with sensitization of tumor cells and protection of normal tissue. We therefore set up ERGO2 (NCT01754350), the first randomized clinical trial of calorically-restricted KD and intermittent fasting (KD-IF) in addition to re-irradiation for recurrent malignant gliomas.
MATERIAL AND METHODS
Patients were randomized 1:1 to re-irradiation combined with either calorically unrestricted diet (standard diet, SD) or KD-IF. The KD-IF schedule included 3 days of KD (21–23 kcal/kg/d), followed by 3 days of fasting and again 3 days of KD. The primary endpoint was progression-free survival (PFS) rate at 6 months (PFS6). Secondary endpoints were PFS, local control, overall survival (OS), frequency of epileptic seizures, rate of ketosis and quality of life.
RESULTS
50 patients were included. Four patients quit the trial before treatment and three patients stopped KD-IF prematurely. Of the 20 patients who completed KD-IF, 17 patients developed ketosis at day 6, and glucose levels declined significantly. KD-IF was well-tolerated with a modest weight loss of -2.1±1.8 kg. No severe adverse events attributable to the diet occurred. There was no difference in PFS6 between the two groups (KD-IF: 20%, SD: 16%). Similarly, no difference in PFS, local PFS6 and OS were observable. Explorative analysis revealed that among patients of the KD-IF group, those who achieved ketosis of at least 1.5 mmol/l had significantly longer PFS compared to those with lesser or no ketosis.
CONCLUSION
KD-IF is feasible and effective in inducing ketosis in heavily pretreated patients with recurrent glioblastoma. However, the short schedule reported here failed to increase the efficacy of re-irradiation.

Abstract
AIMS In the search for blood-based biomarkers of neurodegenerative diseases, we characterized the concentration of total prion protein (t-PrP) in the plasma of neurodegenerative dementias. We aimed to assess its accuracy in this differential diagnostic context. METHODS Plasma t-PrP was measured in 520 individuals including healthy controls (HC) and patients diagnosed with neurological disease control (ND), Alzheimer's disease (AD), sporadic Creutzfeldt-Jakob disease (sCJD), frontotemporal dementia (FTD), Lewy body dementia (LBD) and vascular dementia (VaD). Additionally, t-PrP was quantified in genetic prion diseases and iatrogenic CJD. The accuracy of t-PrP discriminating the diagnostic groups was evaluated and correlated with demographic, genetic and clinical data in prion diseases. Markers of blood-brain barrier impairment were investigated in sCJD brains. RESULTS Compared to HC and ND, elevated plasma t-PrP concentrations were detected in sCJD, followed by FTD, AD, VaD and LBD. In sCJD, t-PrP was associated neither with age nor sex, but with codon 129 PRNP genotype. Plasma t-PrP concentrations correlated with cerebrospinal fluid (CSF) markers of neuro-axonal damage, but not with CSF t-PrP. In genetic prion diseases, plasma t-PrP was elevated in all type of mutations investigated. In sCJD brain tissue, extravasation of immunoglobulin G and the presence of swollen astrocytic end-feet around the vessels suggested leakage of blood-brain barrier as a potential source of increased plasma t-PrP. CONCLUSIONS Plasma t-PrP is elevated in prion diseases regardless of aetiology. This pilot study opens the possibility to consider plasma t-PrP as a promising blood-based biomarker in the diagnostic of prion disease.

Abstract
BACKGROUND Primary angiitis of the central nervous system (PACNS) is a rare but serious condition. A fraction of patients suffering from PACNS concurrently exhibit pronounced cerebral amyloid angiopathy (CAA) which is characterized by deposits of amyloid-β (Aβ) in and around the walls of small and medium-sized arteries of the brain. PACNS with CAA has been identified as a distinct disease entity, termed Aβ-related angiitis (ABRA). Evidence points to an immune reaction to vessel wall Aβ as the trigger of vasculitis. OBJECTIVE To investigate whether the inflammatory response to Aβ has (1) any effect on the status of immune activation in the brain parenchyma and (2) leads to clearance of Aβ from brain parenchyma. METHODS We studied immune activation and Aβ load by quantitative immunohistochemical analysis in brain parenchyma adjacent to affected vessels in 11 ABRA patients and 10 matched CAA controls. RESULTS ABRA patients showed significantly increased immune activation and decreased Aβ loads in the brain parenchyma adjacent to affected vessels. CONCLUSION Our results are in line with the hypothesis of ABRA being the result of an excessive immune response to Aβ and show that this can lead to enhanced clearance of Aβ from the brain parenchyma by immune-mediated mechanisms.

Abstract
OBJECTIVE The substitution of selenium activates the selenium-dependent enzyme glutathione peroxidase, which is important for scavenging free radicals. To date, only limited data are available about the clinical impact of selenium regarding the toxicities due to free radical producing therapies, e.g. irradiation or chemotherapy, and therefore the objective of this study was to investigate the clinical impact of selenium in such therapies. PATIENTS AND METHODS 39 patients (8 female, 31 male) with advanced head and neck cancer were included in a randomised phase II study. The mean age was 63.52+/-9.31 years. Tumour localizations: oral cavity 15 patients, oropharynx 19 patients, hypopharynx 5 patients, carcinoma of unknown primary 1 patient. Group A (n=22) received 500 microg sodium selenite on the days of radiotherapy and 300 microg sodium selenite on days without radiotherapy. Group B (17) was irradiated without any selenium substitution. Both groups were well balanced according to age, gender, localization and stage of the tumour. The RTOG grade of radiation-associated toxicities was evaluated once per week. RESULTS The following serious toxicities were observed (group A vs. group B): dysphagia 22.7% vs. 35.3%, loss of taste 22.7% vs. 47.1%, dry mouth 22.7% vs. 23.5%, and stomatitis 36.4% vs. 23.5%. A statistical trend (Fisher's exact test) was only seen for the loss of taste (p=0.172). The weekly patient analysis (Student's t-test) showed a significant reduction of dysphagia in the selenium group (Group 1) at the last week of irradiation. CONCLUSION This small randomised trial showed limited effects of selenium in the prevention of ageusia (loss of taste) and dysphagia due to radiotherapy of head and neck cancer.

Abstract
e20698 Background: The substitution of selenium effects in activation of the selenium dependent enzyme glutathione peroxidase which is important for scavenging free radicals. Until today only limited data are available about the clinical impact of selenium regarding the toxicities due to free radical producing therapies, e.g. irradiation or chemotherapy. Methods: 39 patients (8 female, 31 male) with advanced head neck cancer were included to a randomized phase II study. All patients had shown a reduced concentration of selenium in the blood and serum (main inclusion criterium). The mean age was 63.52 ± 9.31 years. Tumour localizations: oral cancer 15 patients, oropharynx 19 patients, hypopharynx 5 patients, CUP 1 patient. Group A (n=22) received 500 μg sodium selenite at the days of radiotherapy and 300 μg sodium selenite at holidays or weekend. Group B (17) was irradiated without any selenium substitution. Both groups were well balanced according age, gender, localization and stage of the tumour. We evaluated the RTOG grade of radiation-associated toxicities once per week. Following statistical methods were used: Mantel-Haenssel-χ2-test, Fisher's exact Test. SPSS. Results: We observed the following serious toxicities (group A versus group B): dysphagia 22.7% vs. 35.3%, loss of taste 22.7% vs. 47.1%, dry mouth 22.7% vs. 23.5%, and stomatitis 36.4% vs. 23.5%. A statistical trend (Fisher's exact test) is only seen in the area of loss of taste (p=0.172). The analysis per week had only shown a significant reduction of dysphagia in the selenium group at the last week of irradiation (p=0.04). Conclusions: The small randomized trial has shown limited effects of selenium in the prevention of ageusia (loss of taste) and dysphagia due to radiotherapy because of head and neck cancer. A clinical relevant radioprotection was not observed. [Table: see text]

Abstract
AIM The aim of the present study was a comparative investigation of the functional improvement reported by patients suffering from primary osteoarthritis of the knee or hip undergoing total joint replacement and assessed at 3 months. METHOD In a prospective, controlled clinical trial, 56 patients with primary osteoarthritis of the hip and 59 patients with primary osteoarthritis of the knee undergoing total joint replacement were assessed at two measuring times (day of admission = t1 and 3-month follow-up = t2) using the XSMFA-D (Extra Short Musculoskeletal Function Assessment Questionnaire--German version), WOMAC (Western Ontario and McMasters Universities) arthrosis index and FFb-H OA (Function Assessment Questionnaire Hannover Osteoarthritis). The statistical analysis included effect sizes as standardised response mean, t-test and covariance analysis. RESULTS Both groups of patients demonstrated significant improvements of the musculoskeletal functions measured. The effect sizes between baseline scores and 3-month follow-up scores range from 0.4 to 2.0 and can be considered as large effects. The covariance analysis showed significant differences between patients with osteoarthritis of the hip and knee for almost every score examined. Patients with hip replacement showed large improvements. A significant influence of the presurgery baseline score on the 3-month score was found consistently. Further analysis showed that patients with medium or strong degrees of disability according to the Function index of the XSMFA-D showed the strongest effects of change at 3 months. However, their scores at t2 were less than the scores of the less disabled patients at t1. CONCLUSION We conclude that patients with hip replacement show more improvement 3 months after the surgery than patients with knee replacement. Furthermore, it was seen that patients who were more disabled before surgery achieved more improvement than the less-disabled patients. However, they did not achieve the level of the less disabled patients. Thus, the recommendation that total joint replacement should be performed as late as possible should be reviewed.

Abstract
To validate the provisional findings of a number of smaller studies and explore additional determinants of characteristic diagnostic investigation results across the entire clinical spectrum of sporadic Creutzfeldt-Jakob disease (CJD), an international collaborative study was undertaken comprising 2451 pathologically confirmed (definite) patients. We assessed the influence of age at disease onset, illness duration, prion protein gene (PRNP) codon 129 polymorphism (either methionine or valine) and molecular sub-type on the diagnostic sensitivity of EEG, cerebral MRI and the CSF 14-3-3 immunoassay. For EEG and CSF 14-3-3 protein detection, we also assessed the influence of the time point in a patient's illness at which the investigation was performed on the likelihood of a typical or positive result. Analysis included a large subset of patients (n = 743) in whom molecular sub-typing had been performed using a combination of the PRNP codon 129 polymorphism and the form of protease resistant prion protein [type 1 or 2 according to Parchi et al. (Parchi P, Giese A, Capellari S, Brown P, Schulz-Schaeffer W, Windl O, Zerr I, Budka H, Kopp N, Piccardo P, Poser S, Rojiani A, Streichemberger N, Julien J, Vital C, Ghetti B, Gambetti P, Kretzschmar H. Classification of sporadic Creutzfeldt-Jakob disease based on molecular and phenotypic analysis of 300 subjects. Ann Neurol 1999; 46: 224-233.)] present in the brain. Findings for the whole group paralleled the subset with molecular sub-typing data available, showing that age at disease onset and disease duration were independent determinants of typical changes on EEG, while illness duration significantly influenced positive CSF 14-3-3 protein detection; changes on brain MRI were not influenced by either of these clinical parameters, but overall, imaging data were less complete and consequently conclusions are more tentative. In addition to age at disease onset and illness duration, molecular sub-type was re-affirmed as an important independent determinant of investigation results. In multivariate analyses that included molecular sub-type, time point of the investigation during a patient's illness was found not to influence the occurrence of a typical or positive EEG or CSF 14-3-3 protein result. A typical EEG was most often seen in MM1 patients and was significantly less likely in the MV1, MV2 and VV2 sub-types, whereas VV2 patients had an increased likelihood of a typical brain MRI. Overall, the CSF 14-3-3 immunoassay was the most frequently positive investigation (88.1%) but performed significantly less well in the very uncommon MV2 and MM2 sub-types. Our findings confirm a number of determinants of principal investigation results in sporadic CJD and underscore the importance of recognizing these pre-test limitations before accepting the diagnosis excluded or confirmed. Combinations of investigations offer the best chance of detection, especially for the less common molecular sub-types such as MV2 and MM2.

Abstract
BACKGROUND The prevalence and characteristics of sleep-wake disturbances in sporadic Creutzfeldt-Jakob disease (sCJD) are poorly understood. METHODS Seven consecutive patients with definite sCJD underwent a systematic assessment of sleep-wake disturbances, including clinical history, video-polysomnography, and actigraphy. Extent and distribution of neurodegeneration was estimated by brain autopsy in six patients. Western blot analyses enabling classification and quantification of the protease-resistant isoform of the prion protein, PrPSc, in thalamus and occipital cortex was available in four patients. RESULTS Sleep-wake symptoms were observed in all patients, and were prominent in four of them. All patients had severe sleep EEG abnormalities with loss of sleep spindles, very low sleep efficiency, and virtual absence of REM sleep. The correlation between different methods to assess sleep-wake functions (history, polysomnography, actigraphy, videography) was generally poor. Brain autopsy revealed prominent changes in cortical areas, but only mild changes in the thalamus. No mutation of the PRNP gene was found. CONCLUSIONS This study demonstrates in sporadic Creutzfeldt-Jakob disease, first, the existence of sleep-wake disturbances similar to those reported in fatal familial insomnia in the absence of prominent and isolated thalamic neuronal loss, and second, the need of a multimodal approach for the unambiguous assessment of sleep-wake functions in these patients.

Abstract
AIM The present study had the objective of evaluating the psychometric characteristics of the shortened 16-item version of the German Short Musculoskeletal Function Assessment questionnaire (XSMFA-D), which was designed for routine assessment of functional capacity in patients with various orthopaedic disorders treated either surgically or medically. METHODS A total of 382 patients from seven different samples with either osteoarthritis of the knee, osteoarthritis of the hip, rheumatoid arthritis or rotator cuff tear treated either in surgical hospitals or rehabilitation settings were assessed both before and after treatment. The XSMFA-D was compared with both questionnaires measuring similar constructs and widely accepted indicators of health status in musculoskeletal disorders. Psychometric characteristics were computed. RESULTS The internal consistency (Cronbach's alpha) exceeded 0.90 in most cases for the function index and was between 0.80 and 0.90 in most cases for the bother index of the XSMFA-D. Retest-reliability was between 0.80 and 0.95 for the function index and between 0.60 and 0.92 for the bother index. Correlations between the XSMFA-D subscales and the other questionnaires were substantial, showing construct validity. Criterion validity was also demonstrated as significant relationships with accepted external parameters such as function tests, judgements by physicians, pain self-ratings by patients and disease severity scores were found. Sensitivity to change was as high as for the other assessment instruments used in this study. CONCLUSIONS The XSMFA-D, a very short assessment instrument, proved to be practical, reliable, valid and sensitive to change among the various patient samples studied. It may be recommended for the assessment of patients' state as well as the evaluation of treatments.

Abstract
BACKGROUND An international study of the epidemiologic characteristics of Creutzfeldt-Jakob disease (CJD) was established in 1993 and included national registries in France, Germany, Italy, the Netherlands, Slovakia, and the United Kingdom. In 1997, the study was extended to Australia, Austria, Canada, Spain, and Switzerland. METHODS Data were pooled from all participating countries for the years 1993 to 2002 and included deaths from definite or probable CJD of all etiologic subtypes. RESULTS Four thousand four hundred forty-one cases were available for analysis and included 3,720 cases of sporadic CJD, 455 genetic cases, 138 iatrogenic cases, and 128 variant cases. The overall annual mortality rate between 1999 and 2002 was 1.67 per million for all cases and 1.39 per million for sporadic CJD. Mortality rates were similar in all countries. There was heterogeneity in the distribution of cases by etiologic subtype with an excess of genetic cases in Italy and Slovakia, of iatrogenic cases in France and the UK, and of variant CJD in the UK. CONCLUSIONS This study has established overall epidemiologic characteristics for Creutzfeldt-Jakob disease (CJD) of all types in a multinational population-based study. Intercountry comparisons did not suggest any relative change in the characteristics of sporadic CJD in the United Kingdom, and the evidence in this study does not suggest the occurrence of a novel form of human bovine spongiform encephalopathy infection other than variant CJD. However, this remains a possibility, and countries currently unaffected by variant CJD may yet have cases.

Abstract
Intradural extramedullary bronchiogenic cysts are rare findings. All five reported cases were located cervically or upper thoracically. To our knowledge, we describe the first case of an intraspinal bronchiogenic cyst in a thoracolumbar location. We present the case of a 41-year-old patient with a known spina bifida occulta who suffered from a continuous, sharp, and therapy-refractory pain in the left leg. Magnetic resonance imaging of the thoracic and lumbar vertebra revealed an intradural extramedullar mass at T12 to L1 level. After laminectomy T-12 through L-1/L-2 and longitudinal opening of the dura mater, the cystic mass was shown to be attached to the conus medullaris and the cauda equina, and therefore could be removed only partially. Histopathological examination revealed the diagnosis of bronchiogenic cyst. We therefore conclude that intradural extramedullary bronchiogenic cysts may appear also at thoracolumbar levels. Surgical resection can be achieved with good outcome.

Abstract
A collaborative study of human transmissible spongiform encephalopathies has been carried out from 1993 to 2000 and includes data from 10 national registries, the majority in Western Europe. In this study, we present analyses of predictors of survival in sporadic (n = 2304), iatrogenic (n = 106) and variant Creutzfeldt-Jakob disease (n = 86) and in cases associated with mutations of the prion protein gene (n = 278), including Gerstmann-Sträussler-Scheinker syndrome (n = 24) and fatal familial insomnia (n = 41). Overall survival for each disease type was assessed by the Kaplan-Meier method and the multivariate analyses by the Cox proportional hazards model. In sporadic disease, longer survival was correlated with younger age at onset of illness, female gender, codon 129 heterozygosity, presence of CSF 14-3-3 protein and type 2a prion protein type. The ability to predict survival based on patient covariates is important for diagnosis and counselling, and the characterization of the survival distributions, in the absence of therapy, will be an important starting point for the assessment of potential therapeutic agents in the future.

Abstract
BACKGROUND Complementary/alternative medicine (CAM) is gaining increasing importance especially in the treatment of patients with breast carcinoma. The purpose of this analysis was to investigate the prevalence of CAM in patients with breast carcinoma, to statistically describe the preparations and therapies used, and to determine the reasons for their use, the source of information and the individual perception. PATIENTS AND METHODS The statements of 203 patients with breast carcinoma who underwent radiotherapy were analyzed. The median age was 54 years (range 38-77 years). All patients underwent surgery as first therapy. 36 patients received a second-line radiotherapy because of metastases (27 patients) or local recurrence (9 patients). RESULTS 159 patients (78%) stated to carry out an additional treatment. 31 out of the 36 patients with metastases or local recurrence used CAM. Vitamin preparations (67%), mistletoe therapy (59%), and mineral preparations (33%) were used most frequently. 70% of the patients used a combination of two or more preparations/therapies. The most cited reason for using CAM was the aim of increasing quality of life (28%) and improving the immune system (27%). 72% stated an improvement of their individual perception. The main source of information was the general practitioner or the gynecologist. CONCLUSION The radiotherapist has to take these complementary/alternative therapies into consideration; their importance should be evaluated in further studies.

Abstract
BACKGROUND The changed mineral status is well known in different tumor types. This phenomenon has influenced the redox potential of patients suffering from solid cancers. A prospective trial was conducted to evaluate the specifics for untreated head and neck cancer patients. MATERIAL AND METHODS We included 100 patients with advanced squamous cell carcinoma of the head and neck region before each kind of treatment. Following serum-concentrations were measured by atom absorption spectrometry: selenium, copper, zinc, and ferrum. Additionally we evaluated the activity of glutathion peroxidase and the concentration of malondialdehyde of the serum. RESULTS 66 % of all patients have shown a decreased serum-concentration of selenium. These patients were additionally characterized by decreased activities of endogenous glutathionperoxiase. A third of all patients had decreased zinc and iron levels. Copper was found enhanced in 30 %. In trend the malondialdehyde was increasing due to decreasing selenium levels. CONCLUSIONS Head neck cancer patients show the same characteristic trace element status as other solid tumors: decreased selenium, zinc and iron, increased copper. The therapeutic consequences of these observations are still unclear.

Abstract
Transmissible spongiform encephalopathies are degenerative disorders affecting the central nervous system (CNS) occurring in a variety of species. The causative agent is thought to be composed of an abnormal form of the host encoded prion protein (PrPC), termed PrPSc. The conformational change of PrPC into PrPSc can occur spontaneously, however, it can also be induced by PrPSc. Prion diseases such as bovine spongiform encephalopathy (BSE), scrapie and variant Creutzfeldt-Jakob-Disease (vCJD) are most likely caused by peripheral uptake of prions. The process by which prions proceed to the CNS following peripheral uptake is referred to as neuroinvasion. Infection with prions is thought to occur in two phases: After ingestion prions first replicate in lymphatic tissue and then gain access to the CNS via peripheral nerves. Studies looking at the biochemical and clinical characteristics of BSE and vCJD demonstrated that BSE is most likely responsible for vCJD in humans.

Abstract
Transmissible spongiform encephalopathies (TSE) are dementing diseases and have been known to affect humans for over 90 years. The most common of these is the sporadic form of Creutzfeldt-Jakob disease (sCJD), followed by its familial (fCJD) and an iatrogenic (iCJD) form. 1996 a variant of CJD (vCJD) has been described in the UK, of which so far 131 cases have been observed worldwide. Specific biochemical and neuropathological signatures allow to distinguish between vCJD and sCJD and lead to the hypothesis that vCJD is due to transmission of BSE prions to humans. Although promising therapeutical approaches are being investigated, human TSE remain untreatable entities. Thus preventive measures are essential. In Switzerland the population has been exposed to BSE prions, too, but no case of vCJD as described in the UK has been observed until now. Since 2001, however, a so far unexplained increase of sCJD cases is being observed.

Abstract
Transmissible spongiform encephalopathies (TSEs), or prion diseases, are rare fatal neurodegenerative diseases of humans and animals. Although some TSEs, like scrapie in sheep, have been known to exist for centuries, bovine spongiform encephalopathy (BSE) was recognized only 15 years ago. New variant Creutzfeldt-Jakob disease (nvCJD) of humans is probably caused by consumption of BSE-infected materials. The nature of the infectious agent is not fully elucidated, but substantial evidence suggests that it is devoid of nucleic acids and consists at least in part of an abnormal form of a host protein termed PrP(C). Despite their rarity, prion diseases have become an important topic in public health and basic research because of the connection between nvCJD and BSE and also because of the unusual biological attributes of the infectious agent.

Abstract
Only a few years ago, the idea that transmissible spongiform encephalopathies could be treated pharmacologically would have met with considerable scepticism. Even now, there is no way to cure a patient or animal suffering from a manifest prion disease. But recent, exciting developments seem to indicate that immunological and pharmacological interventions could have some potential for the pre-exposure and post-exposure prophylaxis of prion diseases. Although it is unlikely that we will be able to cure the clinically overt stages of prion diseases in the foreseeable future, palliative and even life-prolonging interventions might no longer be confined to the realm of science fiction.

Abstract
Transmissible spongiform encephalopathies are commonly propagated by extracerebral inoculation of the infectious agent. Indirect evidence suggests that entry into the central nervous system occurs via the peripheral nervous system. Here we have investigated the role of the sympathetic nervous system in prion neuroinvasion. Following intraperitoneal prion inoculation, chemical or immunological sympathectomy delayed or prevented scrapie. Prion titers in spinal cords were drastically reduced at early time points after inoculation. Instead, keratin 14-NGF transgenic mice, whose lymphoid organs are hyperinnervated by sympathetic nerves, showed reduction in scrapie incubation time and, unexpectedly, much higher titers of prion infectivity in spleens. We conclude that sympathetic innervation of lymphoid organs is rate limiting for prion neuroinvasion and that splenic sympathetic nerves may act as extracerebral prion reservoirs.

Abstract
In a randomized phase II trial in Germany, we investigated the clinical and economic impact of amifostine protection against the hematological and oral toxicities of carboplatin administered concurrently with standard fractions of radiotherapy. 28 patients with squamous cell carcinomas of the head and neck received adjunctive or primary radiotherapy (5 days per week with daily fractions of 2 Gy, up to a total dose of 60 Gy) in conjunction with carboplatin (70 mg/m2) on days 1-5 and days 21-26. All patients received radiation encompassing at least 75% of the major salivary glands. Patients were randomized to receive radiation and carboplatin (RCT) alone or RCT preceded by rapid infusion of amifostine (500 mg) on days carboplatin was administered. The 14 patients who received amifostine, in comparison to 14 patients in the control arm, had significantly fewer episodes of grade 3 or 4 thrombocytopenia (p = 0.001), mucositis (p = 0.001), and xerostomia (p = 0.001). The patients receiving amifostine accrued significantly lower supportive care costs for resources related to infection ($241 vs. $1,275, p < 0.01), red blood cell and platelet support ($286 vs. $1,276 p = 0.06) alimentation ($343 vs. $894, p = .01), and hospitalization ($286 vs. $2,429, p < 0.01). Overall, including the costs of amifostine, mean per patient supportive care costs were $4,401 for the amifostine group and $5,873 (p = .02) for the control group. Our results from a randomized phase II trial indicate that selective cytoprotection with amifostine potentially offers clinical and economic benefits in patients with advanced head and neck cancer receiving radiochemotherapy. Additional economic studies alongside randomized phase III trials and from other countries are needed.

Abstract
Spongiform encephalopathies are infectious neurodegenerative diseases caused by pathogens that seem to be devoid of any informational nucleic acids. Histopathologically, these diseases are characterized by spongiform degeneration of the central nervous system. Although the main pathological changes during the course of the disease occur in the brain, the infectious agent accumulates early in lymphoid tissue. The consecutive development of clinical disease depends on the presence of an intact immune system including mature B-cells and follicular dendritic cells. In this article we review the state of knowledge on the routes of neuroinvasion used by the infectious agent in order to gain access to the central nervous system upon entry into extracerebral sites.

Abstract
Spongiform encephalopathies are a group of infectious neurodegenerative diseases. The infectious agent that causes transmissible spongiform encephalopathies was termed prion by Stanley Prusiner. The prion hypothesis states that the partially protease-resistant and detergent-insoluble prion protein (PrPsc) is identical with the infectious agent, and lacks any detectable nucleic acids. Since the latter discovery, transgenic mice have contributed many important insights into the field of prion biology. The prion protein (PrPc) is encoded by the Prnp gene, and disruption of Prnp leads to resistance to infection by prions. Introduction of mutant PrPc genes into PrPc-deficient mice was used to investigate structure-activity relationships of the PrPc gene with regard to scrapie susceptibility. Ectopic expression of PrPc in PrPc knockout mice proved a useful tool for the identification of host cells competent for prion replication. Finally, the availability of PrPc knockout and transgenic mice overexpressing PrPc allowed selective reconstitution experiments aimed at expressing PrPc in neurografts or in specific populations of hemato- and lymphopoietic cells. The latter studies helped in elucidating some of the mechanisms of prion spread and disease pathogenesis.

Abstract
The prion was defined by Stanley B. Prusiner as the infectious agent that causes transmissible spongiform encephalopathies. A pathological protein accumulating in the brain of scrapie-infected hamsters was isolated in 1982 and termed prion protein (PrPSc). Its cognate gene Prnp was identified more than a decade ago by Charles Weissmann, and shown to encode the host protein PrP(C). Since the latter discovery, transgenic mice have contributed many important insights into the field of prion biology, including the understanding of the molecular basis of the species barrier for prions. By disrupting the Prnp gene, it was shown that an organism that lacks PrP(C) is resistant to infection by prions. Introduction of mutant PrP genes into PrP-deficient mice was used to investigate the structure-activity relationship of the PrP gene with regard to scrapie susceptibility. Ectopic expression of PrP in PrP knockout mice proved a useful tool for the identification of host cells competent for prion replication. Finally, the availability of PrP knockout mice and transgenic mice overexpressing PrP allows selective reconstitution experiments aimed at expressing PrP in neurografts or in specific populations of haemato- and lymphopoietic cells. The latter studies have allowed us to clarify some of the mechanisms of prion spread and disease pathogenesis.

Abstract
HISTORY AND CLINICAL FINDINGS A 76-year-old man was admitted for a coronary angiography because of a postinfarction angina. Clinical examination was normal except a grade 2/6 systolic murmur and a slightly impaired vibration sense. INVESTIGATIONS A slight anaemia, a slightly impaired renal function, and a slightly elevated cholesterol level could be found. The ECG showed a chronic anterior myocardial infarction. In the coronary angiography a double vessel disease was seen. TREATMENT AND COURSE A percutaneous transluminal coronary angioplasty of the left anterior descending artery was performed and four stents were implanted. During the procedure a rush occurred in both legs following an appearance of livedo reticularis. Renal function deteriorated and there was an markedly increased number of eosinophils. With a new neurological check a marked peripheral neuropathy could be found. A biopsy of the sural nerve showed a necrotizing granulomatous inflammation of the nerve and the surrounding small arteries. Several small arteries contained needle shaped crystal clefts in their walls. The appearances were of multiple cholesterol emboli. Besides treatment of pain an immunosuppressive therapy with prednisone (100 mg/d) and cyclophosphamide (50 mg/d) showed no improvement. The patient died 2 months after the diagnosis of cholesterol emboli. CONCLUSION Typically, cholesterol embolism occurs in elderly men within the eight weeks after arterial procedure. Diagnosis can be made only by histological examination. Cholesterol emboli syndrome may mimic systemic vasculitis. Therapy trial of cholesterol emboli syndrome usually fails and mortality rate is high.

Abstract
PURPOSE In a retrospective analysis the efficacy of radiotherapy in the treatment of hidradenitis suppurativa was assessed. PATIENTS AND METHODS Data from 231 patients undergoing radiotherapy for hidradenitis suppurativa in the last years in 2 hospitals were analyzed. The patients were treated with an orthovoltage therapy unit with 175 kV, 0.5 mm copper-filtering. The single doses reached from 0.5 Gy to 1.5 Gy up to total doses between 3.0 Gy and 8.0 Gy in one series. In chronic recurrent disease 2 or more series with a total dose of more than 10.0 Gy were given. RESULTS Complete relief of symptoms at the end of radiotherapy was achieved in 89 patients (38%). In 92 patients (40%) there was clear improvement of symptoms. Only 2 patients did not react to radiotherapy. No side effects of radiotherapy occurred. CONCLUSION Radiotherapy should be given more consideration as a treatment option for hidradenitis suppurativa.
