Abstract
Fragile X-associated tremor/ataxia syndrome (FXTAS), a neurodegenerative disorder, affects fragile X (FMR1) gene premutation carriers in late life. Studies have shown cognitive impairments in FXTAS including executive dysfunction, working memory and visuospatial deficits. However, less is known about cognition in females with FXTAS. Thus, we examined semantic processing and verbal memory in female FXTAS patients with event-related potentials (ERPs) and neuropsychological testing. Sixty-one females (34 FXTAS, Mage = 62.7; 27 controls, Mage = 60.4) were studied with 32-channel ERPs during a category judgment task in which semantically congruous (50%) and incongruous items were repeated approximately 10-140 seconds later. N400 and P600 amplitude data were submitted to analysis of covariance. Neuropsychological testing demonstrated lower performance in verbal learning and executive function in females with FXTAS. Event-related potential analyses showed a significant reduction of the N400 congruity effect (incongruous - congruous) in the FXTAS group. The N400 congruity effect reduction in females with FXTAS was mainly due to increased N400 amplitude to congruous new words. No significant abnormalities of the N400 repetition effect or the P600 repetition effect were found, indicating preserved implicit memory and verbal memory, respectively, in females with FXTAS. The decreased N400 congruity effect suggests abnormal semantic expectancy and/or semantic network disorganization in female FXTAS patients. The enhanced N400 amplitude to congruous new words may reflect decreased cognitive flexibility among FXTAS women, making access to less typical category exemplar words more difficult.

Abstract
OBJECTIVE To choose between laparoscopic "vascular hitch" (VH) and dismembered pyeloplasty (DP) in treatment of aberrant lower pole crossing vessels potentially responsible for pelviureteric junction obstruction (PUJO) in older children. PATIENTS AND METHODS Retrospective study of 19 patients treated laparoscopically for PUJO. Based on videos of the procedures, we studied the anatomical relationship between the renal pelvis, the pelviureteric junction, and the aberrant vessels. RESULTS Eight patients had laparoscopic VH and 11 had DP. All patients with DP needed drainage. In the VH group, 7/8 patients were asymptomatic and had decreased pelvic dilation. Half of them accepted MAG3 scintigraphy, and in these patients the obstructive syndrome disappeared completely. The last patient in this group was lost to follow-up. We observed three anatomical variations in the location of polar vessels: type 1 (in front of the dilated pelvis), type 2 (in front of the pelviureteric junction), type 3 (under the pelviureteric junction, resulting in ureteral kinking). CONCLUSION Laparoscopic VH is a simple technique involving no urinary anastomosis or drainage, but we cannot guarantee that the crossing vessels are the sole etiology for PUJO. Following our experience, only patients with type 3 anatomical variations and with a normal pelviureteric junction should be proposed for VH.

Abstract
Marinesco-Sjögren syndrome (MSS; MIM 248800) is an autosomal recessive disorder characterized by congenital cerebellar ataxia, early cataracts, developmental delay, myopathy and short stature. Alterations in the gene SIL1 cause MSS in some patients with typical findings. In this study, molecular investigations including sequencing of the SIL1 gene, western blotting and microscopic investigations in fibroblast cultures were carried out in a cohort of 15 patients from 14 unrelated families, including the large, inbred family reported by Superneau et al., having the clinical features of MSS to provide insights into the pathophysiology of the disorder. A total of seven different mutations were found in eight of the patients from seven families. The mutations caused loss of the BIP-associated protein (BAP) protein in four patients by western blot. Novel clinical features such as dental abnormalities, iris coloboma, eczema and hormonal abnormalities were noticed in some patients, but there was no clear way to distinguish those with and without SIL1 mutations. Cultured fibroblasts contained numerous cytoplasmic inclusion bodies, similar to those identified in the brain of the whoozy mouse in five unrelated patients, three with and two without SIL1 mutations, suggesting some SIL1 negative patients share a common cellular pathogenesis with those who are SIL1 positive.

Abstract
BACKGROUND Platinum-based primary or adjuvant chemoradiation is the treatment of choice for patients with cervical cancer. However, despite national guidelines and international recommendations, many aspects in diagnosis, therapy, and follow-up of patients with cervical cancer are not based on valid data. METHODS To evaluate the current patterns of care for patients with cervical cancer in Germany, a questionnaire with 25 items was sent to 281 radiooncologic departments and out-patient health care centers. RESULTS The response rate was 51%. While 87% of institutions treat 0-25 patients/year, 12 % treat between 26 and 50 and only 1% treat more than 50 patients/year. In 2011, the stage distribution of 1,706 treated cervical cancers were IB1, IB2, IIA, IIB, IIIA/IIIB, and IV in 11, 12, 11, 22, 28, and 16%, respectively. CT (90%) and MRI (86%) are mainly used as staging procedures in contrast to PET-CT with 14%. Interestingly, 27% of institutions advocate surgical staging prior to chemoradiation. In the majority of departments 3D-based (70%) and intensity-modulated radiotherapy (76%) are used for percutaneous radiation, less frequently volumetric arc techniques (26%). Nearly all colleagues (99.3%) apply conventional fractioning of 1.8-2 Gy for external-beam radiotherapy, in 19% combined with a simultaneous integrated boost. Cisplatinum mono is used as a radiosensitizer with 40 mg/m(2) weekly by 90% of radiooncologists. For boost application in the primary treatment, HDR (high-dose rate) brachytherapy is the dominant technique (84%). In patients after radical hysterectomy pT1B1/1B2, node negative and resection in sound margins adjuvant chemoradiation is applied due to the occurrence of 1-4 other risk factors in 16-97%. There is a broad spectrum of recommended primary treatment strategies in stages IIB and IVA. CONCLUSION Results of the survey underline the leading role but also differences in the use of chemoradiation in the treatment of cervical cancer patients in Germany.

Abstract
Premutation alleles (55-200 CGG repeats) of the fragile X mental retardation (FMR1) gene have been linked to various types of clinical involvement ranging from mood and anxiety disorders to immunological disorders and executive function deficits. Carrier females typically have a premutation allele and a normal allele (<55 CGG repeats). Although rare, seven cases of females that carry two expanded alleles (compound heterozygous premutation) have been reported. Here, we report on four members of a family including two compound heterozygous premutation sisters with similar CGG allele sizes, affected with different levels of clinical severity.

Abstract
The clinical progression of Alzheimer disease (AD) was studied in European subjects under treatment with AChE inhibitors (AChE-I) in relation to geographical location over a 2-years period. One thousand three hundred and six subjects from 11 European countries were clustered into 3 regions (North, South, West) and investigated with biannual follow-up over 2 years. Primary outcomes were cognitive, functional and behavioral measures. Caregiver burden, hospital admission and admission to nursing home were also recorded. Participant cognitive function declined non-linearly over time (MMSE: -1.5 pts/first year, -2.5 pts/second year; ADAScog: + 3.5 pts/first year, + 4.8 pts/second year), while the progression of behavioral disturbances (NPI scale) was linear. Neither scale showed regional differences, and progression of the disease was similar across Europe despite different health care systems. Functional decline (ADL, IADL) tended to progress more rapidly in Southern Europe (p=0.09), while progression of caregiver burden (Zarit Burden Interview) was most rapid in Northern Europe (5.6 pts/y, p=0.04). Incidences of hospital admission (10.44, 95%CI: 8.13-12.75, p < 0.001) and admission to nursing home (2.97, 95%CI: 1.83-4.11, p < 0.001) were lowest in Southern Europe. In general cognitive and functional decline was slower than in former cohorts. European geographical location reflecting differences in culture and in health care system does not impact on the progression of AD but does influence the management of AD subjects and caregiver burden.

Abstract
Anophthalmia/microphthalmia (A/M) represent severe developmental ocular malformations. Currently, mutations in known genes explain less than 40% of A/M cases. We performed whole-genome copy number variation analysis in 60 patients affected with isolated or syndromic A/M. Pathogenic deletions of 3q26 (SOX2) were identified in four independent patients with syndromic microphthalmia. Other variants of interest included regions with a known role in human disease (likely pathogenic) as well as novel rearrangements (uncertain significance). A 2.2-Mb duplication of 3q29 in a patient with non-syndromic anophthalmia and an 877-kb duplication of 11p13 (PAX6) and a 1.4-Mb deletion of 17q11.2 (NF1) in two independent probands with syndromic microphthalmia and other ocular defects were identified; while ocular anomalies have been previously associated with 3q29 duplications, PAX6 duplications, and NF1 mutations in some cases, the ocular phenotypes observed here are more severe than previously reported. Three novel regions of possible interest included a 2q14.2 duplication which cosegregated with microphthalmia/microcornea and congenital cataracts in one family, and 2q21 and 15q26 duplications in two additional cases; each of these regions contains genes that are active during vertebrate ocular development. Overall, this study identified causative copy number mutations and regions with a possible role in ocular disease in 17% of A/M cases.

Abstract
BACKGROUND Gastrointestinal endoscopies are increasingly being carried out with sedation. All of the drugs used for sedation are associated with a certain risk of complications. Data currently available on sedation-associated morbidity and mortality rates are limited and in most cases have substantial methodological limitations. The aim of this study was to record severe sedation-associated complications in a large number of gastrointestinal endoscopies. METHODS Data on severe sedation-associated complications were collected on a multicentre basis from prospectively recorded registries of complications in the participating hospitals (median documentation period 27 months, range 9 - 129 months). RESULTS Data for 388,404 endoscopies from 15 departments were included in the study. Severe sedation-associated complications occurred in 57 patients (0.01 %). Forty-one percent of the complications and 50 % of all complications with a fatal outcome (10/20 patients) occurred during emergency endoscopies. In addition, it was found that 95 % of the complications and 100 % of all fatal complications affected patients in ASA class ≥ 3. CONCLUSIONS Including nearly 400,000 endoscopies, this study represents the largest prospective, multicenter record of the complications of sedation worldwide. The analysis shows that sedation is carried out safely in gastrointestinal endoscopy. The morbidity and mortality rates are much lower than previously reported in the literature in similar groups of patients. Risk factors for the occurrence of serious complications include emergency examinations and patients in ASA class ≥ 3.

We aimed to characterize nerve fibres in the proximal and distal areas of the peritoneal endometriotic lesions in order to understand the chronic inflammatory process in endometriosis. METHODS Peritoneal endometriotic lesions (proximal area) (n = 17), the matching unaffected peritoneum (distal area) and healthy peritoneum of patients without endometriosis (n = 15) were analysed with the neuronal markers PGP 9.5, calbindin, calretinin and parvalbumin. Peritoneal fluids of women with and without endometriosis were used for Western blot analysis and for the neuronal growth assay. The protein expression of neuronal PC-12 cells incubated with peritoneal fluids was analysed. RESULTS The overall nerve fibre density was significantly reduced in the distal area of the lesion when compared with the proximal area or with healthy peritoneum. The density of calbindin-, calretinin- and parvalbumin-positive nerve fibres was significantly increased in the endometriosis group. Calretinin expression was elevated in the peritoneal fluid of women with symptomatic endometriosis when compared with women with asymptomatic endometriosis. Furthermore, PC-12 cells incubated with peritoneal fluid of women with endometriosis showed a higher proliferation rate and a stronger neurite outgrowth than the control group. PC-12 cells incubated in peritoneal fluids of women with endometriosis expressed less calretinin but more calbindin than the control group. CONCLUSIONS Calcium-binding proteins seem to be increased in endometriosis-associated nerve fibres and might play an important role in the chronic inflammatory condition and the pain pathogenesis of endometriosis.

Abstract
Barrett's esophagus is characterized by the replacement of squamous epithelium by columnar epithelium that is intestinal metaplasia-positive or -negative in the distal esophagus. Gastroesophageal reflux disease, which is frequent and prolonged in esophageal atresia, probably plays a major role in the development of Barrett's esophagus through repeated mucosal damage. Long-term acid exposure contributes to carcinogenesis in Barrett's esophagus of intestinal type, but its effect on gastric metaplasia is less well defined. Recent studies have suggest that metaplasia arises in about 15% of patients with esophageal atresia, with a lag time to developing metaplasia from initial surgical correction of about 10 years. Preliminary data from an ongoing multicenter study including 88 patients with esophageal atresia aged 15-19 years showed gastric metaplasia in 42% of patients (29 fundic and 7 cardial metaplasia), while one patient presented intestinal metaplasia. Esophageal mucosal abnormalities can be observed in esophageal atresia patients at endoscopy despite the absence of symptoms. Whether prolonged, aggressive, acid suppression is beneficial in these situations remains to be determined. Barrett's metaplasia can be removed by endoscopic mucosal resection or destroyed with endoscopic ablative techniques, such as photodynamic therapy, radiofrequency ablation, and cryotherapy. The risk of developing esophageal carcinoma is still a controversial issue as only a few clinical cases have been reported in young adults with esophageal atresia. As late complications of esophageal atresia, particularly esophagitis and Barrett's esophagus, are increasingly being recognized, long-time systematic follow up of the esophageal mucosa including multistage biopsies is therefore required even in asymptomatic patients.

Abstract
Small supernumerary marker chromosomes (sSMCs) are structurally abnormal chromosomes that cannot be characterized by karyotype. In many prenatal cases of de novo sSMC, the outcome of pregnancy is difficult to predict because the euchromatin content is unclear. This study aimed to determine the presence or absence of euchromatin material of 39 de novo prenatally ascertained sSMC by array-comparative genomic hybridization (array-CGH) or single nucleotide polymorphism (SNP) array. Cases were prospectively ascertained from the study of 65,000 prenatal samples [0.060%; 95% confidence interval (CI), 0.042-0.082]. Array-CGH showed that 22 markers were derived from non-acrocentric markers (56.4%) and 7 from acrocentic markers (18%). The 10 additional cases remained unidentified (25.6%), but 7 of 10 could be further identified using fluorescence in situ hybridization; 69% of de novo sSMC contained euchromatin material, 95.4% of which for non-acrocentric markers. Some sSMC containing euchromatin had a normal phenotype (31% for non-acrocentric and 75% for acrocentric markers). Statistical differences between normal and abnormal phenotypes were shown for the size of the euchromatin material (more or less than 1 Mb, p = 0.0006) and number of genes (more or less than 10, p = 0.0009). This study is the largest to date and shows the utility of array-CGH or SNP array in the detection and characterization of de novo sSMC in a prenatal context.

Abstract
Introduction: In spite of the existence of guidelines and international recommendations, many aspects in the diagnosis, therapy and follow-up of patients with cervical cancer are not based on validated data. A broad spectrum of different opinions and procedures concerning the therapy for patients with cervical cancer is under controversial discussion by the responsible gynaecologists in German hospitals. Methods: The present study is intended to picture the current treatment situation for cervical cancer in Germany. For this purpose a specially developed questionnaire with questions divided into 19 subsections was sent to all 688 gynaecological hospitals in Germany. Results: The response rate to the questionnaire was 34 %. 91 % of the hospitals treated between 0 and 25 patients with cervical cancer per year. 7.5 % treated between 26 and 50 and 1.4 % of the hospitals more than 50 patients per year. The bimanual examination was the most frequently used staging method (98 %); PET-CT was the least used staging method (2.3 %). Interestingly 48 % of the hospitals used surgical staging. The great majority of the hospitals (71 %) used abdominal radical hysterectomy (Wertheim-Meigs operation) to treat their patients. TMMR via laparotomy was used by 13 %. 16 % of the hospitals performed laparoscopic or robot-assisted radical hysterectomies. The sentinel concept was hardly used even in the early stages. It must be emphasised that in 74 % of the hospitals radical hysterectomies were performed even in cases with positive pelvic lymph nodes and in 43 % also in cases with positive paraaortic lymph nodes. The therapy of choice for FIGO IIB cancers is primary radiochemotherapy (RCTX) in 21 % of the hospitals; operative staging followed by radiochemotherapy in 24 % and treatment by radical hysterectomy followed by adjuvant RCTX was employed in this situation by 46 % of the hospitals. In 15-97 % of the hospitals for node-negative and in sano resected patients in stage pT1B1/1B2 after radical hysterectomy, an adjuvant RCTX is recommended when further risk factors exist (LVSI, tumour > 4 cm, age < 40 years, adenocarcinoma, S3). Conclusion: A broad spectrum of differing staging and therapy concepts is in use for patients with cervical cancer in Germany. A standardisation of therapy is needed. An update of national guidelines could help to achieve more transparency and a standardisation of treatment for patients with cervical cancer.

Abstract
Em um delineamento experimental usando o fatorial 3x2, três crioprotetores internos, glicerol (GLI), etilenoglicol (EG) e dimetilformamida (DMF), e dois externos, gema de ovo (GEMA) e lipoproteína de baixa densidade (LDL), avaliaram-se a motilidade ao descongelamento de GLI-GEMA 53,9±1,96, sendo superior aos demais tratamentos (P<0,05). Na avaliação de morfologia ao descongelamento, não houve diferença (P>0,05) entre os tratamentos EG-GEMA 68,3±1,58, EG-LDL 72,2±2,39 e DMF-GEMA 68,7±1,67 que foram mais altos que os demais (P<0,05). A avaliação de integridade de membrana por fluorescência ao descongelamento GLI-GEMA 34,2±2,28 e EG-GEMA 30,9±1,32 não diferiram entre si (P>0,05), mas foram mais elevados que os demais (P<0,05), enquanto que a HOST dos tratamentos DMF-GEMA 13,6±1,30 e DMF-LDL 9,8±0,78 diferirem entre si (P<0,05) e foram mais baixas que as demais (P<0,05). O uso de etilenoglicol associado à gema de ovo pode ser uma alternativa ao uso de glicerol nos protocolos de congelamento de sêmen de touros.

Abstract
Wound healing requires a proper functioning of keratinocytes that migrate, proliferate and lead to a competent wound closure. Impaired wound healing might be due to a disturbed keratinocyte function caused by the wound environment. Basically, chronic wound fluid (CWF) differs from acute wound fluid (AWF). The aim of this study was to analyse the effects of AWF and CWF on keratinocyte function. We therefore investigated keratinocyte migration and proliferation under the influence of AWF and CWF using MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] test and scratch assay. We further measured the gene expression by qRT-PCR regarding growth factors and matrixmetalloproteinases (MMPs) involved in regeneration processes. AWF had a positive impact on keratinocyte proliferation over time, whereas CWF had an anti-proliferative effect. Keratinocyte migration was significantly impaired by CWF in contrast to an undisturbed wound closure under the influence of AWF. MMP-9 expression was strongly upregulated by CWF compared with AWF. Keratinocyte function was significantly impaired by CWF. An excessive induction of MMP-9 by CWF might lead to a permanent degradation of extracellular matrix and thereby prevent wounds from healing.

Abstract
The case of a female patient with a suprasellar optic glioma is reported, who was admitted to the intensive care unit due to decompensated diabetes insipidus with hypernatremia of 194 mmol/l. The sodium concentration was reduced slowly over 4 days and the patient recovered without sequelae. Based on this case the article deals with the pathophysiology and therapy of hypernatremia. An increase in extracellular osmolarity leads to augmented production of intracellular osmolytes in order to maintain the cell volume constant. Due to this counterregulation correction of the sodium concentration must be done with caution.

Abstract
INTRODUCTION Impaction of foreign bodies in the upper gastrointestinal tract represents a rare endoscopic emergency regarding the danger of organic lesions. Therefore, the therapeutic strategy, rational postinterventional monitoring and potential consequences for the course in the future are often not clear. METHODS Out of all oesophagogastroduodenoscopies performed between 2008 and 2010 (n = 10,830), the endoscopies due to bolus impaction were analysed retrospectively concerning endoscopic findings, course of intervention and causative predisposing factors using descriptive statistics. RESULTS In the study period, endoscopy was performed in 45 different patients 49 times when foreign body impaction was suspected. In 38 cases (77.6%) a foreign body could be detected by endoscopy, most frequently a meat bolus (65.8%), followed by dental prostheses and tablets. Endoscopic removal could be successfully performed in 97.4%. An operation was necessary in only one patient. A macroscopically unremarkable upper gastrointestinal tract without any predisposing conditions for foreign body impaction could be detected in 33.3%. In one case eosinophilic oesophagitis could be diagnosed histologically. The foreign body was pushed into the stomach by the "push technique" in 54.1%. The foreign body removal was performed as an ambulant intervention in 63.2%. DISCUSSION In the majority of cases, impacted foreign bodies of the upper gastrointestinal tract could be removed safely by endoscopy, e.g., using the "push technique". However, the therapeutic strategy should be individually adjusted based on the consistancy of the foreign body. If no predisposing conditions can be found, histological diagnosis should be performed to detect potential eosinophilic oesophagitis early enough.

Abstract
Background: Aim of the study was to compare the quality of loop excision using a colposcope with results using the VITOM system. Results compared included cervical volume removed, intra- and postoperative complications, and positive resection margins. Methods: A total of 200 patients with histologically confirmed high-grade cervical premalignant lesions, persistent atypical cytological results and/or suspicious colposcopic findings, and cytological and histological discrepancies were included in the study. In transformation zone type 1 (T1) only a superficial cone biopsy was done, in zones type 2 and 3 (T2 and T3) a superficial outside cone biopsy or a deeper inside cone biopsy were done respectively, followed by endocervical curettage. Volume of removed tissue, complications, and positive resection margins were compared for the colposcopy and the VITOM groups. Findings: Demographic and reproductive features were similar between groups. In the VITOM group 49 % of patients had zone T1, 30 % had zone T2, and 21 % had zone T3. In the group of patients managed by colposcopy, 48, 45, and 7 % of patients had zone T1, T2 and T3 zone, respectively (p < 0.01). A "top hat" procedure was done in 65 % of patients in the VITOM group and in 38 % of patients in the colposcopy group (p < 0.05). Mean volume of removed cervical tissue measured was similar, with 1.2 cm3 measured in the VITOM group and 1.14 cm3 in the colposcopy group (p > 0.05). There were no significant differences in the type of procedure or the mean volume of removed tissue. Results were similar for both groups with respect to positive resection margins and complications. Conclusion: VITOM is a safe and reliable system. Results using the VITOM system are comparable to those obtained with conventional colposcopy. The potential advantage of VITOM is the broader availability of endoscopic systems in the operating theatre.

Abstract
Cardiac arrest with subsequent cardiopulmonary resuscitation causes an ischemic reperfusion syndrome of the whole body resulting in localized damage of particularly sensitive organs, such as the brain and heart, together with systemic sequelae. The main factor is a generalized activation of inflammatory reactions resulting in symptoms similar in many aspects to those of sepsis. Systemic inflammation strengthens organ damage due to disorders in the macrocirculation and microcirculation due to metabolic imbalance as well as the effects of direct leukocyte transmitted tissue destruction. The current article gives an overview on the role of inflammation following cardiac arrest and presents in detail the underlying mechanisms, the clinical symptoms and possible therapeutic approaches.

Abstract
Compararam-se as concentrações de cálcio, glicose e insulina em ovelhas gestantes e não gestantes submetidas ao teste de tolerância à glicose (TTG). Oito ovelhas gestantes (GG) e oito não gestantes (NG) foram submetidas ao TTG por meio da administração endovenosa de uma solução de glicose, na dose de 500mg/kg de peso vivo. Amostras de sangue foram coletadas nos tempos de -15, zero, 15, 30, 45, 60, 90, 120, 150 e 180 minutos, sendo zero min o momento da infusão, para avaliação da concentração sanguínea de glicose, cálcio e insulina. Foi avaliada a taxa de metabolização de glicose e insulina, por meio do cálculo da área sob a curva (ASC). As concentrações de glicose, cálcio, insulina e a ASC da insulina não diferiram entre os grupos (P>0,05), entretanto as três últimas ASCs da glicose foram mais elevados nas gestantes (P<0,05), que correspondem ao período entre 90 e 180min. O teste de correlação de Pearson revelou correlação negativa entre concentração de cálcio e insulina nas gestantes (P<0,05). Estes resultados indicam menor taxa de metabolização de glicose em ovelhas gestantes e uma possível relação de cálcio e insulina no terço final de gestação.

Abstract
BACKGROUND To date, the safety and tolerability of proton pump inhibitors (PPIs) have been demonstrated in studies of up to 10 years. AIM To report on the tolerability, safety and efficacy of up to 15 years' continuous treatment with pantoprazole in patients with severe acid-peptic disease. METHODS Following healing of endoscopically confirmed peptic ulcer or reflux oesophagitis during 4-12 weeks' treatment with pantoprazole (40-80 mg/day), adult patients received open-label maintenance treatment with pantoprazole (40-160 mg/day) for up to 15 years in a single centre combined study (10-year initial study; 5-year extension study). Safety assessments were carried out using endoscopy, clinical examination, clinical laboratory investigations, serum gastrin determination, gastric mucosal histology and mucosal endocrine cell quantification. RESULTS The safety set comprised 142 patients. At 12 weeks, healing rates were 95.8%. During long-term treatment, mean fasting gastrin levels rose from baseline to moderate levels throughout the study. Mean enterochromaffin-like cell density showed a moderate initial increase during the first 3 years, remaining stable thereafter. These changes were not associated with any clinically relevant changes of the gastric mucosa. Patients with successful Helicobacter pylori eradication showed long-term regression of antral and corpus gastritis during continued pantoprazole treatment. CONCLUSIONS Daily pantoprazole maintenance therapy for up to 15 years for severe acid-peptic disease is effective and well tolerated, with no identified safety concerns. The longest study to date, these data provide reassuring evidence for the long-term safety of pantoprazole.

Abstract
BACKGROUND The objective of the KORA-Age research consortium is to assess the determinants and consequences of multimorbidity in the elderly and to look into reasons for successful aging in the general public. PATIENTS AND METHODS In the KORA-Age cohort study 9,197 persons were included who where born in the year 1943 or before and participants of previous KORA cohort studies conducted between 1984 and 2001 (KORA: Cooperative Health Research in the Region of Augsburg). The randomized intervention study KORINNA (Coronary infarct follow-up treatment in the elderly) tested a nurse-based case management program with 338 patients with myocardial infarct and included an evaluation in health economics. RESULTS A total of 2,734 deaths were registered, 4,565 participants submitted a postal health status questionnaire and 4,127 participants were interviewed by telephone (response 76.2% and 68.9% respectively). A gender and age-stratified random sample of the cohort consisting of 1,079 persons took part in a physical examination (response 53.8%). CONCLUSION The KORA-Age consortium was able to collect data in a large population-based sample and is contributing to the understanding of multimorbidity and successful aging.

Abstract
Liver cell transplantation (LCT) is considered a new therapeutic strategy for the treatment of acute liver failure and inborn metabolic defects of the liver. Although minimally invasive, known safety risks of the method include portal vein thrombosis and pulmonary embolism. Since no systematic data on these potential side effects exist, we investigated the toxicological profile of repeated intraportal infusion of allogeneic liver cells in 30 rabbits under GLP conditions. Rabbit liver cells were administered once daily for 6 consecutive days at 3 different dose levels, followed by a 2-week recovery period. No test item-related mortality was observed. During cell infusion, clinical findings such as signs of apathy and hyperventilation, moderate elevations of liver enzymes ALT and AST and a slight decrease in AP were observed, all fully reversible. Cell therapy-related macroscopic and histological findings, especially in liver and lungs, were observed in animals of all dose groups. In conclusion, the liver and lungs were identified as potential toxicological target organs of intraportal allogeneic liver cell infusion. A NOAEL (no observed adverse effect level) was not defined because of findings observed also in the low-dose group. No unexpected reactions became apparent in this GLP study. Overall, LCT at total doses up to 12 % (2 % daily over 6 days) of the total liver cell count were tolerated in rabbits. Observed adverse effects are not considered critical for treatment in the intended patient populations provided that a thorough monitoring of safety relevant parameters is in place during the application procedure.

Abstract
Fraser syndrome (FS) and microphthalmia syndromic 9 (MCOPS9) are autosomal recessive conditions with distinct, and some overlapping features affecting the ocular, respiratory and cardiac systems. Mutations in FRAS1 and FREM2 occur in FS, and mutations in STRA6 occur in MCOPS9. We report two sibships, in the same family, where four deceased offspring had ocular, respiratory and cardiac abnormalities. Two sibs with microphthalmia had syndactyly and laryngeal stenosis, suggesting a clinical diagnosis of FS. Our results indicate that they were compound heterozygotes for novel FRAS1 mutations, p.Cys729Phe and p.Leu3813Pro. The other two sibs, first cousins to the first sib pair, had anophthalmia, lung hypoplasia and cardiac anomalies, suggesting a retrospective diagnosis of MCOPS9. Our results indicate compound heterozygous STRA6 mutations, a novel frameshift leading to p.Tyr18* and a p.Thr644Met mutation. The one surviving individual from these sibships is heterozygous for the p.Tyr18*STRA6 mutation and has bilateral ocular colobomata and microphthalmia. This work emphasises the need for careful phenotypic characterisation to determine genes for assessment in ocular syndromic conditions. It also indicates that heterozygous STRA6 mutations may rarely contribute to microphthalmia and coloboma.
