Background
Endogenous Cushing’s syndrome (CS) results in increased cardiovascular morbidity and mortality. This risk seems to be lower in patients with incidentally discovered mild autonomous cortisol secretion (MACS) but without the clinical features of CS. We aimed to describe and compare the cardiac morphology and function in patients with overt CS and MACS to a representative sample of a local prospective population-based cohort (STAAB).
Methods/Results: We comprehensively characterized 40 patients with overt CS (mean age 47 ± 13 years, 75% women) and 18 patients with MACS (62 ± 11 years, 56% women; both p ≤ 0.001 when compared to CS) including detailed transthoracic echocardiography. Logistic regression adjusted for age and sex showed no significant differences between both groups regarding body mass index (BMI), systolic and diastolic blood pressure (BP), lipids, HbA1c, and echocardiographic parameters of cardiac morphology and function (table). The comparison with STAAB participants (n = 4965, 55 ± 12 years, 52% women; logistic regression adjusted for age and sex) revealed significantly higher BMI, triglycerides, HbA1c, and diastolic but not systolic BP (table). Compared to STAAB participants, patients exhibited a smaller left ventricle (LV) with thicker septal and posterior walls, and a less favorable diastolic function. LV ejection fraction (LVEF) was higher, although longitudinal contraction, measured by tricuspid annular plane systolic excursion (TAPSE), and LV global longitudinal strain (GLS) were lower in both ventricles compared to STAAB participants (table).
Conclusion
Patients with both MACS or CS exhibited a compromised metabolic profile and diastolic function pattern when compared to a population-based cohort. Higher LVEF despite lower GLS suggests a compensatory increase in LV radial contraction in states of hypercortisolism. Cardiac impairment was similar in patients with CS or MACS suggesting an adverse effect of hypercortisolism even at clinically inconspicuous levels. Abstract Figure.

Abstract
OBJECTIVE The present study aimed to characterize involuntary psychiatric admissions and coercive measures within psychiatric hospitals regarding their temporal development and processual aspects. Moreover, the influence of socio-economic factors on involuntary admissions and coercive measures was investigated. METHODS Different data sets from the federal state of North-Rhine Westphalia (NRW) were used in this study. In addition to a survey in which n = 33 hospitals responded (40.7%), official data from the Federal Health Ministry were analysed over a decade regarding involuntary admissions and coercive measures. These data were available for all n = 54 districts, respectively, all n = 81 psychiatric hospitals in NRW. Datasets were mainly analysed comparing different socio-economic clusters. RESULTS The hospital admission rate increased significantly over time (from 1.12 to 1.34 per 1000 inhabitants) within ten years. However, whereas the admission rates differed significantly between socio-economic clusters, the amount of coercive measures used in the hospitals did not. Compared to general psychiatry and addiction medicine, geriatric psychiatry had the highest amount of involuntary admissions (12.2% under public law, 14.1% under civil law). Furthermore, most coercive measures lasted at least an hour. CONCLUSION It seems that, despite intense discussions and enhanced efforts to reduce coercion, there are still some neglected aspects, such as the need for coercive measures and their duration, particularly in the geriatric psychiatric setting. In addition, the results show that further approaches to prevent involuntary admissions are needed to address other stakeholders beyond the hospitals and further aspects of the socio-economic environment.

Abstract
BACKGROUND Liver resection is the only curative therapeutic option for intrahepatic cholangiocarcinoma (ICC), but the approach to recurrent ICC is controversial. This study analysed the outcome of liver resection in patients with recurrent ICC. METHODS Demographic, radiological, clinical, operative, surgical pathological and follow-up data for all patients with a final surgical pathological diagnosis of ICC treated in a tertiary referral centre between 2001 and 2015 were collected retrospectively and analysed. RESULTS A total of 190 patients had liver resection for primary ICC. The 1-, 3- and 5-year overall survival (OS) rates were 74·8, 56·6 and 37·9 per cent respectively. Independent determinants of OS were age 65 years or above (hazard ratio (HR) 2·18, 95 per cent c.i. 1·18 to 4·0; P = 0·012), median tumour diameter 5 cm or greater (HR 2·87, 1·37 to 6·00; P = 0·005), preoperative biliary drainage (HR 2·65, 1·13 to 6·20; P = 0·025) and local R1-2 status (HR 1·90, 1·02 to 3·53; P = 0·043). Recurrence was documented in 87 patients (45·8 per cent). The mean(s.d.) survival time after recurrence was 16(17) months. Independent determinants of recurrence were median tumour diameter 5 cm or more (HR 1·71, 1·09 to 2·68; P = 0·020), high-grade (G3-4) tumour (HR 1·63, 1·04 to 2·55; P = 0·034) and local R1 status (HR 1·70, 1·09 to 2·65; P = 0·020). Repeat resection with curative intent was performed in 25 patients for recurrent ICC, achieving a mean survival of 25 (95 per cent c.i. 16 to 34) months after the diagnosis of recurrence. Patients deemed to have unresectable disease after recurrence received chemotherapy or chemoradiotherapy alone, and had significantly poorer survival. CONCLUSION Patients with recurrent ICC may benefit from repeat surgical resection.

Abstract
Abstract
As the WHO-Health-in-all-Policies-concept suggests many of the health-related aspects of the social, physical and economic environments can be modified within the community setting. In reality, developing and implementing population-based health initiatives is often challenging for both communities and researchers. To guide future efforts of community health initiatives, we systematically analyzed challenges we encountered and the lessons learned.
We systematically reviewed daily logbooks, meeting minutes and press releases about the initiative to identify successes, unexpected challenges and barriers in its implementation. Comments from two reflective workshops held in the partner community identified additional areas of knowledge. Retrospective content analysis of these sources uncovered emerging process-related themes.
Success was evident in a high degree of citizen participation in initiative-related forums. Challenges included a greater need to a) develop a common vision before starting initiative activities, b) establish an effective collaboration between community residents and our team, c) create more transparent lines of communication, foster trust and better manage community expectations. Establishing a project office in the community for regular updates, trust building and partnering with a professional communication agency were key steps that helped turn some challenges into successes. Barriers identified were missing resources both within the community and our team, a limited time period and limited possibilities of reach into all systems within the community (e.g. kindergartens).
The use of the method of retrospective process analysis helped to uncover detailed insights into the operational implementation process of a community health initiative. These insights serve as a transfer of practical knowledge, which intends to enable researchers and practioneers within communities to plan and conduct their community health initiatives to large success.
Key messages
Analyzing the process of health initiatives retrospectively uncovers detailed insights into implementation processes and helps to understand successes, challenges and barriers of the initiative. Insights into the implementation process of health initiatives function as guidance to other researchers and practioneers to support future efforts in the field of community health.

Abstract
Abstract
Background
Neighborhoods and their characteristics play a key role for establishing and maintaining health and wellbeing of their residents. However, before programs promoting health and wellbeing in the neighborhood can be planned and implemented, it is necessary to identify local needs for action. This is especially important for the stakeholders that work in the neighborhood (e.g., employees of the local community, headmasters of schools). We thus developed exemplary for Herzogenried -a neighborhood in the German city of Mannheim- a barometer that aims to assess and monitor health and wellbeing in the neighborhood and indicates potential needs for action.
Methods
We conducted a detailed literature search to identify indicators that were associated with health and wellbeing in neighborhoods. Based on the search we created a primary list of indicators, which we presented and discussed during 15 meetings with a total of 26 different stakeholders. Available data on the indicators agreed on were checked for accuracy, statistically processed, and visualized for incorporation into the barometer.
Results
The barometer consists of the following eight dimensions which in total include 80 indicators: population structure, population development, household structure, material wellbeing, education, family and upbringing, health, and personal security. The barometer also includes a map that displays structural characteristics of the neighborhood such as physicians, schools, supermarkets. An important challenge we faced was the availability of indicators as some of them were only accessible at the community level or for specific age groups.
Conclusions
The barometer offers a comprehensive overview on the neighborhood, provides first hints for the local stakeholders on needs for action, and helps to prioritize the issues that should be addressed to promote health and wellbeing in Herzogenried. It will also serve as a prototype for other neighborhoods in the future.
Key messages
The barometer was planned to serve as a transferable tool to identify and prioritize action steps for neighborhood development and to help promoting health and wellbeing of their residents. As the barometer displays indicators relevant for various community stakeholders it can serve to identify joint goals and thus foster stronger trans-sectoral collaboration at the neighborhood level.

Abstract
We used Bayesian evolutionary analysis to study linguistic data and infer phylogenetic trees of language evolution. Languages were encoded as binary strings indicating the presence or absence of members of cognate classes, the equivalence of classes of words with similar meaning, and shared ancestry. These strings formed the alignment data used to compute the posterior likelihood of a tree with respect to Bayes’ formula. Informative priors are crucial for testing hypotheses regarding the age of common ancestry and divergence times and should include as much available information as possible. Here, we investigated the birth–death process as a method to construct tree priors specifically suitable for modeling the evolution of cognate data. To test these models, we will use a dataset of the languages from Vanuatu, an island nation featuring world’s highest language density.

Abstract
The large number of nanomaterial-based applications emerging in the materials and life sciences and the foreseeable increasing use of these materials require methods that evaluate and characterize the toxic potential of these nanomaterials to keep safety risks to people and environment as low as possible. As nanomaterial toxicity is influenced by a variety of parameters like size, shape, chemical composition, and surface chemistry, high throughput screening (HTS) platforms are recommended for assessing cytotoxicity. Such platforms are not yet available for genotoxicity testing. Here, we present first results obtained for application-relevant nanomaterials using an automatable genotoxicity platform that relies on the quantification of the phosphorylated histone H2AX (γ-H2AX) for detecting DNA double strand breaks (DSBs) and the automated microscope system AKLIDES® for measuring integral fluorescence intensities at different excitation wavelengths. This platform is used to test the genotoxic potential of 30 nm-sized citrate-stabilized gold nanoparticles (Au-NPs) as well as micellar encapsulated iron oxide nanoparticles (FeOx-NPs) and different cadmium (Cd)-based semiconductor quantum dots (QDs), thereby also searching for positive and negative controls as reference materials. In addition, the influence of the QD shell composition on the genotoxic potential of these Cd-based QDs was studied, using CdSe cores as well as CdSe/CdS core/shell and CdSe/CdS/ZnS core/shell/shell QDs. Our results clearly revealed the genotoxicity of the Au-NPs and its absence in the FeOx-NPs. The genotoxicity of the Cd-QDs correlates with the shielding of their Cd-containing core, with the core/shell/shell architecture preventing genotoxicity risks. The fact that none of these nanomaterials showed cytotoxicity at the chosen particle concentrations in a conventional cell viability assay underlines the importance of genotoxicity studies to assess the hazardous potential of nanomaterials.

Abstract
Ayurveda is a traditional Indian system of medicine that is more than 3000 years old, consisting mostly of a specific diet, oily infusions mainly in the area of the head, enemas, medicinal plants and yoga. It is based on a naturopathic and anthropological belief in association with the hinduistic religion. Ayurveda has been practiced very successfully in India but so far it has only been insufficiently appreciated by western medicine, especially psychiatry. An exception is Scharfetter from Zürich who wrote a review article on this topic in 1976. Nevertheless, it is probable that particularly the immunological mechanisms of psychotic and affective disorders can be influenced by the application of ayurvedic methods; however, the empirical data source, particularly with respect to randomized controlled trials and meta-analyses regarding psychiatric disorder symptoms is limited. Even if Ayurveda is applied in a highly individualized manner, this should be rapidly improved for further evidential assessment. First positive experiences in the neuropsychiatric field in Germany are already available.

Abstract
PURPOSE To investigate the value of contrast-enhanced ultrasound (CEUS) in histologic prediction of focal liver lesions after liver transplantation. MATERIALS AND METHODS 10 focal liver lesions in 10 patients after liver transplantation were scanned using CEUS and the CEUS results were compared with the histopathological results. RESULTS Among 10 focal liver lesions, 7 proofed to be histopathological benign and 3 lesions proofed to be histopathological malignant. All lesions (100%) were correctly report as benign or malignant in the report of the CEUS examination. CONCLUSION CEUS can be helpful in the differentiation of benign and malignant focal liver lesions in patients after liver transplantation and can be used in clinical management of focal liver lesions.

Abstract
PURPOSE To analyse the diagnostic performance of contrast-enhanced ultrasound (CEUS) in patients with vascular complications and transplant rejection compared to histopathological results. MATERIALS AND METHODS Our study consisted of 45 retrospectively analysed patients that underwent liver transplantations between January 1993 and December 2015 and developed post-transplant vascular complications with transplant rejection. CEUS examinations took place between September 2006 and December 2015. CEUS findings were correlated with histopathological results. RESULTS CEUS showed a sensitivity of 61.5%, a specificity of 100.0%, a positive predictive value (PPV) of 100.0% and a negative predictive value (NPV) of 86,5% in the detection of vascular complications with post-transplant rejection. 5 examinations were reported as normal whereas the histopathological result showed a transplant rejection (false-negative). CONCLUSION CEUS might be a useful additional non-invasive technique for the assessment of vascular complications with post-transplant rejection in patients after liver transplantation.

Abstract
Complex trends in occupancy determined by many influencing factors, clear state-specific differences in imprisonment practices as well as recently implemented statutory alterations to the appropriate paragraphs in criminal law, underline the necessity for qualitative high-grade concomitant research of German forensic commitment; however, neither the structural prerequisites nor an adequate data situation are currently present in order to do justification to this aim. Not even the total number of patients currently accommodated in forensic commitment can be elucidated from the publicized (partial) statistics. This consensus paper, which was formulated by three research institutes active at the state level, describes the limited possibilities for current forensic healthcare research and raises the demand for a nationwide uniform data situation on patients in forensic commitment. Furthermore, how the appropriate elicitation instrument should be organizationally and structurally achieved, is sketched from a scientific perspective. This article aims at initiating a discussion on a sustainable improvement in the prerequisites for healthcare research in German forensic commitment and targets a sensitization of decision makers in politics and administration for this topic.

Abstract
OBJECTIVES To determine the inpatient management for patients with acute idiopathic facial palsy (IFP) in Thuringia, Germany. DESIGN Population-based study. SETTING All inpatients with IFP in all hospitals with departments of otolaryngology and neurology in 2012, in the German federal state, Thuringia. MAIN OUTCOME MEASURES Patients' characteristics and treatment were compared between departments, and the probability of recovery was tested. RESULTS A total of 291 patients were mainly treated in departments of otolaryngology (55%) and neurology (36%). Corticosteroid treatment was the predominant therapy (84.5%). The probability to receive a facial nerve grading (odds ratio [OR=12.939; 95% confidence interval [CI]=3.599 to 46.516), gustatory testing (OR=6.878; CI=1.064 to 44.474) and audiometry (OR=32.505; CI=1.485 to 711.257) was significantly higher in otolaryngology departments, but lower for cranial CT (OR=0.192; CI=0.061 to 0.602), cerebrospinal fluid examination (OR=0.024; CI=0.006 to 0.102). A total of 131 patients (45%) showed a recovery to House-Brackmann grade≤II. A pathological stapedial reflex test (Hazard ratio [HR]=0.416; CI=0.180 to 0.959) was the only independent diagnostic predictor of worse outcome. Prednisolone dose >500 mg (HR=0.579; CI 0.400 to 0.838) and no adjuvant physiotherapy (HR=0.568; CI=0.407 to 0.794) were treatment-related predictors of worse outcome. CONCLUSIONS Inpatient treatment of IFP seems to be highly variable in daily practice, partly depending on the treating discipline and despite the availability of evidence-based guidelines. The population-based recovery rate was worse than reported in clinical trials.

Abstract
PURPOSE To evaluate the sensitivity and specificity of contrast-enhanced ultrasound (CEUS) and computed tomography (CT) in the diagnosis of malignancies after liver transplantation. MATERIALS AND METHODS A total of 23 patients with suspicious liver masses after liver transplantation with initial imaging series between September 2006 and September 2015 were statistically analysed. CEUS and CT were compared in their diagnosis of malignancy with CT being the gold standard. Out of 23 patients 9 patients showed malignant masses in CT, which could also be detected in 7 out 9 of cases using CEUS. RESULTS CEUS showed a sensitivity of 77.8%, a specificity of 100.0%, a positive predictive value (PPV) of 100.0% and a negative predictive value (NPV) of 87,5% in comparison with CT being the gold standard. In 2 cases CT showed a malignancy, contrary to the CEUS examination that was reported as normal. CONCLUSION CEUS seems to be an alternative option for the evaluation of malignant masses in liver transplant patients. CEUS shows a high specificity and PPV in the detection of malignant liver masses.

Abstract
BACKGROUND The symptom "delusions" is a central psychopathological symptom in psychiatric diseases. Since the beginning of psychiatry various disciplines have attempted to explain and understand delusions but even now no generally accepted definition of this phenomenon exists. AIM A comprehensive review of current psychopathological and neurobiological theories of delusions is given. MATERIAL AND METHODS PubMed and Google scholar searches were performed using the keywords "delusion", "psychodynamic" and "neurobiology", both in English and German. Relevant German textbooks of psychiatry were also included. DISCUSSION A differentiated perspective of the phenomenon of delusions appears to be necessary to approach this complex and fascinating symptom. A one-dimensional approach does not do justice to the complexity of delusions. The various explanatory approaches can increasingly be linked to each other and are no longer considered to be mutually exclusive.

Abstract
PURPOSE To compare the sensitivity and specificity of contrast-enhanced ultrasound (CEUS) and magnetic resonance imaging (MRI) in the evaluation of unclear renal lesions to the histopathological outcome. MATERIALS AND METHODS A total of 36 patients with a single unclear solid renal lesion with initial imaging studies between 2005 and 2015 were included. CEUS and MRI were used for determining malignancy or benignancy and initial findings were correlated with the histopathological outcome. Out of the 36 renal masses a total of 28 lesions were malignant (77.8%) and 8 were found to be benign (22.2%). Diagnostic accuracy was testes by using the histopathological diagnosis as the gold standard. RESULTS CEUS showed a sensitivity of 96.4%, a specificity of 100.0%, a positive predictive value (PPV) of 100.0% and a negative predictive value (NPV) of 88,9%. MRI showed a sensitivity of 96.4%, a specificity of 75.0%, a PPV of 93.1% and a NPV of 85.7%. Out of the 28 malignant lesions a total of 18 clear cell renal carcinomas, 6 papillary renal cell carcinomas and 4 other malignant lesions, e.g. metastases, were diagnosed. Out of the 8 benign lesions a total 3 angiomyolipomas, 2 oncocytomas, 1 benign renal cyst and 2 other benign lesions, e.g. renal adenomas were diagnosed. Using CEUS, 1 lesion was falsely identified as benign. Using MRI, 2 lesions were falsely identified as benign and 1 lesion was falsely identified as malignant. CONCLUSION CEUS is an useful method which can be additionally used to clinically differentiate between malignant and benign renal lesions. CEUS shows a comparable sensitivity, specificity, PPV and NPV to MRI. In daily clinical routine, patients with contraindications for other imaging modalities can particularly benefit using this method.

Abstract
Bullous autoimmune diseases are organ-specific disorders characterized by an autoantibody-mediated blistering of skin and mucous membranes. The detection of tissue-bound and serum autoantibodies is prerequisite for the diagnosis of autoimmune blistering diseases. The individual entities of this group may be difficult to differentiate on clinical grounds alone. An accurate diagnosis is however important for prognosis and therapy. A preliminary diagnostic step includes direct and indirect immunofluorescence microscopy, which provide information about the binding pattern and isotype of autoantibodies and allow the diagnosis of the autoimmune blistering disease. Subsequent characterization of the molecular specificity of autoantibodies is necessary for the exact classification of autoimmune bullous dermatoses. The quantitative measurement of autoantibodies against structural proteins of the skin may be often used to assess disease severity at follow-up.

Abstract
Diagnosis of cutaneous forms of lupus erythematosus (LE), including chronic discoid LE (CDLE) and subacute cutaneous LE (SCLE), is usually based on characteristic clinical and histopathological findings. We aimed to visualize morphological changes in lesions of cutaneous LE using optical coherence tomography (OCT), and to correlate the OCT findings with histopathology. Six patients with CDLE and five patients with SCLE were investigated. Prior to skin biopsy, OCT assessment was performed on previously marked lesions. The images of OCT and corresponding histology were evaluated side-by-side on the PC screen. The thickening and disruption of the entrance signal in OCT images correlated with the hyperkeratosis which was observed in the histological sections. Atrophy of the epidermis, which was demonstrated by histology, could also be detected in the OCT pictures showing a thinned layer below the entrance signals. On OCT, a patchy reduction of reflectivity was observed in the upper dermis corresponding to dense patchy, partly lichenoid, lymphocytic infiltrates and oedema of the upper dermis. Furthermore, OCT images displayed increased signal-free cavities which histopathologically corresponded to dilated vessels in the upper dermis. All OCT parameters studied significantly (P < 0.05) correlated with histopathological features as indicated by coefficients of correlation ranging from 0.55 to 0.94. OCT enables to demonstrate micromorphological changes in cutaneous LE which correlate with histopathological findings. Nevertheless, the current technique does not allow one to visualize definite diagnostic features of cutaneous LE. However, OCT may be a promising method for objective monitoring of LE activity and treatment effects over time in vivo

Abstract
Collagen vascular diseases and vasculitides comprise various diseases, which may affect virtually every organ system. Therefore, their diagnosis and management is often an interdisciplinary challenge. Because of the heterogeneous symptoms, these diseases have significant overlap, which interferes with the clinical diagnosis and may require additional investigation. Therefore, a rational and comprehensive diagnostic work-up should be performed at the initial presentation before initiation of therapy. The detection of antinuclear (ANA) or anticell antibodies by indirect immunofluorescence microscopy on Hep2 cells is used to screen for autoantibodies in collagen vascular diseases. The molecular specificity of autoantibodies should be further characterized using immunoassays with recombinant or purified protein. When systemic autoimmune disease is suspected, the function of the frequently affected organs should be evaluated. The immunopathological findings should always be interpreted in the context of clinical, histological, and imaging data. The detection of autoantibodies is helpful for the initial diagnosis, provides prognostic information, may indicate involvement of organs or systems and some parameters may also be used for disease monitoring. The clinical significance of autoantibodies is emphasized by the fact that their detection constitutes diagnostic criteria for most collagen vascular diseases and several vasculitides. The screening for ANCA may be performed using immunoassays with recombinant myeloperoxidase and proteinase 3 or by indirect immunofluorescence microscopy on granulocytes. In this article, the current diagnostic tools and their relevance for the diagnosis and monitoring of systemic autoimmune diseases with primary skin involvement are reviewed.

Abstract
BACKGROUND Fuchs endothelial corneal dystrophy (FECD) is one of the most common indications for corneal transplants. FECD is associated with various genes, e.g., COL8A2 or SLC4A11. Among other things a TGC trinucleotide repeat expansion in intron 2 of the TCF4 gene has been characterised in FECD patients and the allele G of the polymorphism rs613872 in intron 3 of the same gene has been associated with this disease. Our intention was to investigate sources in molecular genetics in the German population and to calculate the odds ratio as indicator for the chance to suffer from FECD. PATIENTS AND METHOD 42 unrelated FECD patients, 93 unrelated controls and 17 members of a family with four FECD affected patients have been examined for the described changes in the TCF4 gene. After amplification of the TGC repeats with specific PCR the obtained products were electrophoretically divided according to their length and investigated with a triplet-primed PCR. Polymorphism rs613872 was analysed by Sanger sequencing. All coding exons of the adjacent genes TCF4 and LOXHD1 were sequenced in six patients in order to exclude potential disease associated mutations. RESULTS 33 out of 42 unrelated analysed patients (79 %) had a TGC repeat expansion (> 50 TGC repeats) in intron 2 of the TCF4 gene. Out of 93 controls only 10 (10.8 %) showed an expanded allele. In the family the four diseased and four healthy subjects of the 17 examined family members had an expanded allele. Analysis of the polymorphism rs613872 in intron 3 of the TCF4 gene exhibited 33 of 42 unrelated patients (78.6 %) heterozygous TG and four homozygous GG (9.5 %). 65 of 93 controls were homozygous TT (69.9 %) and only 21 heterozygous TG (22.6 %). Of the 17 family members nine had the genotype TG, including the four FECD patients. Sequencing of the coding exons of TCF4 and LOXHD1 in six patients showed no variant described with FECD. The odds ratio as indicator for being affected by FECD in our data for the expanded TGC allele is 30. The chance of being affected is thus 30 times higher when someone exhibits the expanded allele. For a carrier of the risk allele G the chance is 16.5 times higher. DISCUSSION An expanded TGC allele with more than 50 TGC repeats in intron 2 and the described risk allele G of the polymorphism rs613872 in intron 3 of the TCF4 gene appear as an association to FECD. The chance to be affected by FECD is up to 30 times higher. With molecular genetics also donors with clinically unknown FECD may be detected.

Abstract
BACKGROUND Obsessive-compulsive symptoms are common with a high prevalence of 3.5 % in adults with intellectual disabilities (ID). The present article reviews different aspects (epidemiology, aetiology, clinical features, diagnostic methods and treatment). METHOD A computerized search of the relevant literature was done using Pubmed and Cochrane databases. RESULTS Difficulties in diagnosing obsessive-compulsive disorder in adults with ID result from difficulties in differentiating true compulsions from stereotypical and repetitive behaviors as also from the fact that patients with ID have cognitive and language impairments. Genetic diseases are most frequently the cause of congenital intellectual disability but only a few with ID are affected by OCD symptoms. Low-dose serotonergic anti-depressants are used in the treatment of OCD symptoms. However, there are only a few controlled treatment studies of obsessive-compulsive symptoms in people with ID. CONCLUSION Further research especially regarding treatment of OCD in people with ID is urgently needed.

Abstract
The response of the vitreous after panretinal argon laser photocoagulation was followed over a period of 60 days. Two phases can be discerned. An an immediate reaction to the disturbance of the blood-retinal barrier at the site of the pigment epithelium the total protein content and malate dehydrogenase activity rise sharply within 3 days, 4- to 5-fold above a normal. The more protracted increase of lysosomal enzyme activities which reach their peak heigh after 14 days only, can be attributed to the action and proliferation of phagocytic cells. 2 months after treatment all parameters have returned to their normal levels.
