Abstract
Mucopolysaccharidosis II (MPS II) is a rare, life-limiting lysosomal storage disease caused by reduced iduronate-2-sulfatase activity. Patients experience broad ranging signs and symptoms, including bone and joint manifestations. This study reported on orthopedic involvement and management in patients with MPS II using 15 years of data from the Hunter Outcome Survey (HOS). Of the 245 patients in the study population, 90.2% had skeletal deformity (median onset, 2.8 years), 76.7% had upper body stiffness (onset, 4.2 years), and 61.2% had lower body stiffness (onset, 5.3 years); 63.7% of patients had at least three joint manifestations. Orthopedic manifestations were common in adults and children with MPS II, and in patients with and without cognitive impairment. Joint range of motion (JROM) was restricted in all joints assessed (shoulder, elbow, hip, wrist, knee, and ankle). Little correlation was observed between JROM measurements, subjective reports of joint stiffness and limited function, and 6-minute walk test results. Patients with joint stiffness and limited function were generally more likely to have central and peripheral nervous system, pulmonary, and cardiovascular manifestations than those without these symptoms. Carpal tunnel decompression was the most common orthopedic surgery (recorded in 49/245 patients [20.0%]), but orthopedic surgeries were uncommon overall. Our findings highlight the need for routine monitoring of orthopedic manifestations using multiple assessment types in patients with MPS II to help inform clinical decision-making and improve patient quality of life. They also underline the contribution of factors other than orthopedic manifestations to the walking ability of patients with MPS II.

Abstract
Approximately two-thirds of patients with mucopolysaccharidosis II (MPS II; Hunter syndrome) have neuronopathic disease, with central nervous system involvement; one-third have non-neuronopathic disease. This analysis of data from the Hunter Outcome Survey (HOS) compared the clinical manifestations and surgical and nonsurgical procedure history in patients with neuronopathic or non-neuronopathic MPS II. Prospective patients were identified in July 2018 in HOS for inclusion in this analysis as those with stable cognitive impairment status as assessed at 10 years of age and at a minimum of one follow-up visit at 11 to <20 years of age. Patients were stratified according to cognitive impairment status at 10 years into neuronopathic and non-neuronopathic groups, and clinical manifestations and surgical and nonsurgical procedure history were compared between the two groups. In total, 193 patients had cognitive impairment status assessments available (at 10 years and 11 to <20 years of age), 151 of whom had stable cognitive impairment status and were included; 100/151 (66.2%) were in the neuronopathic group and 51/151 (33.8%) in the non-neuronopathic group. The proportion of patients demonstrating manifestations by system organ class and the number of surgical and nonsurgical procedures per patient were broadly comparable in the neuronopathic and non-neuronopathic groups both before and after patients' 10th birthdays. The most common manifestations before patients' 10th birthdays, including facial features, joint stiffness and limited function, and hepatomegaly were reported in >80% of patients in both groups. For the neuronopathic and non-neuronopathic groups, the median [10th percentile, 90th percentile] number of different types of surgical and nonsurgical procedures per patient (3 [1, 6] and 3 [1, 7], respectively) and of all procedures per patient (4 [1, 10] and 5 [2, 11], respectively) before patients' 10th birthdays were similar, although the type of procedure may have differed. Thus, in the first two decades of life, patients with non-neuronopathic disease were found to have similar somatic manifestations to those of the neuronopathic group and undergo procedures for complications as often as those with neuronopathic disease.

Abstract
Abstract
Objective
The treatment of complex proximal humerus fractures in elderly patients is not yet fully eluci-dated. Of all treatment options reverse shoulder arthroplasty (RSA) and non operative treat-ment (NOT) appear to provide the best results. Evidence to guide the choice between the two is sparse. Therefore, this review provides an overview of the available evidence on RSA versus non-operative treatment.
Methods
Studies comparing RSA and NOT were included for direct comparison by systematic re-view and pooled analysis for patient rated outcome and range of motion. Additionally, indirect comparison of case-series and non-comparative studies on either treatment modalities was performed separately.
Results
Comparative: Reverse shoulder arthroplasty resulted in better patient rated outcome scores and better range of motion. Pain and treatment satisfaction scores were better after RSA. Non comparative studies reported similar patient rated and range of motion scores for both RSA and after NOT.
Conclusion
The functional and range of motion outcomes after RSA seem satisfactory and potentially superior to NOT in elderly patients. The complication rate is acceptably low and an overall revision rate of 5% was found. These results should however be viewed in light of distinct differences in patient characteristics between treatment groups.

Abstract
Abstract
Objective
This meta-analysis aims to compare open reduction and internal fixation with a plate (ORIF) versus nailing for humeral shaft fractures in terms of healing, complications, general quality of life and shoulder/elbow function.
Methods
PubMed/Medline/Embase/CENTRAL/CINAHL was searched for both randomised clinical trials (RCT) and observational studies comparing ORIF with nailing for humeral shaft fractures. Effect estimates were pooled across studies using random effects models and presented as weighted odds ratio (OR) or risk difference (RD) with corresponding 95% confidence interval (95%CI). Subgroup analysis was performed stratified by study design (RCTs and observational studies).
Results
A total of ten RCT's (525 patients) and eighteen observational studies (4906 patients) were included. The effect estimates obtained from observational studies and RCT's were similar in direction and magnitude. More patients treated with nailing required re-intervention (RD: 2%; OR 2.0, 95%CI 1.0 – 3.8) with shoulder impingement being the most predominant indication (17%). Temporary radial nerve palsy secondary to operation occurred less frequently in the nailing group (RD: 2%; OR 0.4, 95% CI 0.3 – 0.6). Notably, all but one of the radial nerve palsies resolved sponta-neously in each groups. Nailing leads to a faster time to union (mean difference: -1.9 weeks, 95%CI -2.9 – -0.9), lower infection rate (RD: 2%; OR: 0.5, 95%CI 0.3 – 0.7) and shorter operation duration (mean difference: -26 minutes, 95%CI -37 – -14). No differences were found regarding non-union, general quality of life, functional shoulder scores, and total upper extremity scores.
Conclusion
Nailing carries a lower risk of infection, postoperative radial nerve palsy, shorter operation duration, and time to union. Absolute differences, however, are small and almost all patients with radial nerve palsy recovered spontaneously. Satisfactory results can be achieved with both treatment modalities and both techniques have their inherent pros and cons.

Abstract
The hips are frequently involved in inheritable diseases which affect the bones. The clinical and radiological presentation of these diseases may be very similar to common hip disorders as developmental dysplasia of the hip, osteoarthritis and avascular necrosis, so the diagnosis may be easily overlooked and treatment may be suboptimal. Mucopolysaccharidosis (MPS) and Mucolipidosis (ML II and III) are lysosomal storage disorders with multisystemic involvement. Characteristic skeletal abnormalities, known as dysostosis multiplex, are common in MPS and ML and originate from intra-lysosomal storage of glycosaminoglycans in cells of the cartilage, bones and ligaments. The hip joint is severely affected in MPS and ML. Hip pathology results in limitations in mobility and pain from young age, and negatively affects quality of life. In order to better understand the underlying process that causes hip disease in MPS and ML, this review first describes the normal physiological (embryonic) hip joint development, including the interplay between the acetabulum and the femoral head. In the second part the factors contributing to altered hip morphology and function in MPS and ML are discussed, such as abnormal development of the pelvic- and femoral bones (which results in altered biomechanical forces) and inflammation. In the last part of this review therapeutic options and future perspectives are addressed.

Abstract
Mucopolysaccharidosis IVA is an autosomal recessive condition caused by mutations in the GALNS gene, which encodes N-acetylgalactosamine-6-sulfatase, also called galactosamine-6-sulfatase (GALNS). A reduction in or absence of effective GALNS leads to faulty catabolism of keratan sulfate and chondroitin-6-sulfate within the lysosome; their accumulation causes cell, tissue, and organ dysfunction. The connective tissue, cartilage, ligaments, and bone of patients with Morquio A syndrome are particularly affected. Patients with Morquio A syndrome are at high risk of neurological complications because of their skeletal abnormalities; many patients are in danger of cervical myelopathy due to odontoid hypoplasia and ligamentous laxity leading to atlantoaxial subluxation. The multisystemic involvement of patients with Morquio A syndrome requires treatment by multidisciplinary teams; not all members of these teams may be aware of the potential for subluxation and quadriparesis. A multinational, multidisciplinary panel of 10 skeletal dysplasia or Morquio A syndrome specialists convened in Miami, FL on December 7 and 8, 2012 to develop consensus recommendations for early identification and effective management of spinal cord compression, for anesthesia and surgical best practices, and for effectual cardiac and respiratory management in patients with Morquio A syndrome. The target audience for these recommendations includes any physician who may encounter a patient with Morquio A syndrome, however doctors who do not have access to the full spectrum of specialists and resources needed to support patients with Morquio A syndrome should attempt to refer patients to a center that does. Physicians who manage Morquio A syndrome or comorbid conditions within specialty centers should review these expert panel recommendations and fully understand the implications of spinal cord instability for their own practices.

Abstract
OBJECTIVE To assess clinical features and general health status of adult patients with mucopolysaccharidosis (MPS) VI. METHODS This report includes the clinical history of patients older than 18 years with slowly progressing MPS VI and the retrospective analysis of the outcomes of available data collected between September 2003 and October 2008 at the Center of Pediatric and Adolescent Medicine, University Medical Center, Johannes Gutenberg-University of Mainz, Germany. Variables included were urinary glycosaminoglycan (uGAG) level, mutation analysis, body height, forced vital capacity (FVC), 6-minute walk test, echocardiographic findings, the need for craniocervical decompression surgery, orthopaedic findings and ophthalmological assessments. RESULTS The analysis included nine patients with MPS VI aged 19-29 years. The median age at diagnosis was 12 (range 6-20) years. At the time of the assessment (median age 25 years), median uGAG was 29 (range 15-149) μg/mg creatinine and median height 152 (range 136-161) cm. All patients had a FVC below standard values, seven showed reduced endurance in the 6-minute-walk test, all had valve changes with valve replacement in three, two underwent craniocervical decompression surgery, two underwent carpal tunnel surgery, five had ear/nose/throat (ENT) interventions, seven had hip pain/dysplasia, seven had corneal clouding and two were visually impaired. CONCLUSIONS Although patients with slowly progressing MPS VI are a heterogeneous group showing disease manifestations in several organs, they seem to have some typical characteristics in common. Despite the attenuated clinical course, many of these patients show severe morbidity. Therefore, early diagnosis and proper follow-up and treatment are essential.

Abstract
Mucopolysaccharidosis type II (MPS II or Hunter syndrome) is a rare, inherited disorder caused by deficiency of the lysosomal enzyme iduronate-2-sulfatase. As a result of this deficiency, glycosaminoglycans accumulate in lysosomes in many tissues, leading to progressive multisystemic disease. The cardiopulmonary and neurological problems associated with MPS II have received considerable attention. Orthopedic manifestations are common but not as well characterized. This study aimed to characterize the prevalence and severity of orthopedic manifestations of MPS II and to determine the relationship of these signs and symptoms with cardiovascular, pulmonary and central nervous system involvement. Orthopedic manifestations of MPS II were studied using cross-sectional data from the Hunter Outcome Survey (HOS). The HOS is a global, physician-led, multicenter observational database that collects information on the natural history of MPS II and the long-term safety and effectiveness of enzyme replacement therapy. As of January 2009, the HOS contained baseline data on joint range of motion in 124 males with MPS II. In total, 79% of patients had skeletal manifestations (median onset, 3.5 years) and 25% had abnormal gait (median onset, 5.4 years). Joint range of motion was restricted for all joints assessed (elbow, shoulder, hip, knee and ankle). Extension was the most severely affected movement: the exception to this was the shoulder. Surgery for orthopedic problems was rare. The presence of orthopedic manifestations was associated with the presence of central nervous system and pulmonary involvement, but not so clearly with cardiovascular involvement. Orthopedic interventions should be considered on an individual-patient basis. Although some orthopedic manifestations associated with MPS II may be managed routinely, a good knowledge of other concurrent organ system involvement is essential. A multidisciplinary approach is required.

Abstract
Mucopolysaccharidosis type II (MPS II) is a rare, life-limiting, X-linked recessive disease characterised by deficiency of the lysosomal enzyme iduronate-2-sulfatase. Consequent accumulation of glycosaminoglycans leads to pathological changes in multiple body systems. Age at onset, signs and symptoms, and disease progression are heterogeneous, and patients may present with many different manifestations to a wide range of specialists. Expertise in diagnosing and managing MPS II varies widely between countries, and substantial delays between disease onset and diagnosis can occur. In recent years, disease-specific treatments such as enzyme replacement therapy and stem cell transplantation have helped to address the underlying enzyme deficiency in patients with MPS II. However, the multisystem nature of this disorder and the irreversibility of some manifestations mean that most patients require substantial medical support from many different specialists, even if they are receiving treatment. This article presents an overview of how to recognise, diagnose, and care for patients with MPS II. Particular focus is given to the multidisciplinary nature of patient management, which requires input from paediatricians, specialist nurses, otorhinolaryngologists, orthopaedic surgeons, ophthalmologists, cardiologists, pneumologists, anaesthesiologists, neurologists, physiotherapists, occupational therapists, speech therapists, psychologists, social workers, homecare companies and patient societies. Take-home message Expertise in recognising and treating patients with MPS II varies widely between countries. This article presents pan-European recommendations for the diagnosis and management of this life-limiting disease.

Abstract
Among a nationally representative sample of adults with an alcohol use disorder, the authors tested whether perceived stigmatization of alcoholism was associated with a lower likelihood of receiving alcohol-related services. Data were drawn from a face-to-face epidemiologic survey of 34,653 adults interviewed in 2004-2005 who were aged 20 years or older and residing in households and group quarters in the United States. Alcohol abuse/dependence was diagnosed by using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, version (AUDADIS-IV). The stigma measure used was the Perceived Devaluation-Discrimination Scale. The main outcome was lifetime intervention including professional services and 12-step groups for alcohol disorders. Individuals with a lifetime diagnosis of an alcohol use disorder were less likely to utilize alcohol services if they perceived higher stigma toward individuals with alcohol disorders (odds ratio = 0.37, 95% confidence interval: 0.18, 0.76). Higher perceived stigma was associated with male gender (β = -0.75; P < 0.01), nonwhite compared with non-Hispanic white race/ethnicity, lower income (β = 1.0; P < 0.01), education (β = 1.48; P < 0.01), and being previously married (β = 0.47; P = 0.02). Individuals reporting close contact with an alcohol-disordered individual (e.g., relative with an alcohol problem) reported lower perceived stigma (β = -1.70; P < 0.01). A link between highly stigmatized views of alcoholism and lack of services suggests that stigma reduction should be integrated into public health efforts to promote alcohol treatment.

Abstract
Hunter syndrome is a rare, X-linked disorder caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase. In the absence of sufficient enzyme activity, glycosaminoglycans accumulate in the lysosomes of many tissues and organs and contribute to the multisystem, progressive pathologies seen in Hunter syndrome. The nervous, cardiovascular, respiratory, and musculoskeletal systems can be involved in individuals with Hunter syndrome. Although the management of some clinical problems associated with the disease may seem routine, the management is typically complex and requires the physician to be aware of the special issues surrounding the patient with Hunter syndrome, and a multidisciplinary approach should be taken. Subspecialties such as otorhinolaryngology, neurosurgery, orthopedics, cardiology, anesthesiology, pulmonology, and neurodevelopment will all have a role in management, as will specialty areas such as physiotherapy, audiology, and others. The important management topics are discussed in this review, and the use of enzyme-replacement therapy with recombinant human iduronate-2-sulfatase as a specific treatment for Hunter syndrome is presented.

Abstract
BACKGROUND Undiagnosed patients with the attenuated form of mucopolysaccharidosis (MPS) type I often have joint symptoms in childhood that prompt referral to a rheumatologist. A survey conducted by Genzyme Corporation of 60 European and Canadian rheumatologists and pediatric rheumatologists demonstrated that < 20% recognized signs and symptoms of MPS I or could identify appropriate diagnosis tests. These results prompted formation of an international working group of rheumatologists, pediatric rheumatologists, and experts on MPS I to formulate a rheumatology-based diagnostic algorithm. The resulting algorithm applies to all MPS disorders with musculoskeletal manifestations.Bone and joint manifestations are prominent among most patients with MPS disorders. These life-threatening lysosomal storage diseases are caused by deficient activity of specific enzymes involved in the degradation of glycosaminoglycans. Patients with attenuated MPS disease often experience diagnostic delays. Enzyme replacement therapy is now commercially available for MPS I (laronidase), MPS II (idursulfase), and MPS VI (galsulfase). PRESENTATION OF THE HYPOTHESIS Evolving joint pain and joint contractures in the absence of inflammation should always raise the suspicion of an MPS disorder. All such patients should undergo urinary glycosaminoglycan (uGAG) analysis (not spot tests for screening) in a reputable laboratory. Elevated uGAG levels and/or an abnormal uGAG pattern confirms an MPS disorder and specific enzyme testing will determine the MPS type. If uGAG analysis is unavailable and the patient exhibits any other common sign or symptom of an MPS disorder, such as corneal clouding, history of hernia surgery, frequent respiratory and/or ear, nose and throat infections; carpal tunnel syndrome, or heart murmur, proceed directly to enzymatic testing. Refer patients with confirmed MPS to a geneticist or metabolic specialist for further evaluation and treatment. TESTING OF THE HYPOTHESIS We propose that rheumatologists, pediatric rheumatologists, and orthopedists consider our diagnostic algorithm when evaluating patients with joint pain and joint contractures. IMPLICATIONS OF THE HYPOTHESIS Children and young adults can suffer for years and sometimes even decades with unrecognized MPS. Rheumatologists may facilitate early diagnosis of MPS based on the presenting signs and symptoms, followed by appropriate testing. Early diagnosis helps ensure prompt and appropriate treatment for these progressive and debilitating diseases.

Abstract
BACKGROUND AND OBJECTIVE Allergic skin and respiratory diseases show a high prevalence in most industrial countries. In addition, during the last years ragweed colonization has increased in Europe. Ambrosia pollen ( AMBROSIA ARTEMISIIFOLIA L. - common ragweed) are highly allergenic. Due to the late flowering time (august/September) of ragweed this can result in increasing health threats for allergic populations. This is of particular importance for those who already are sensitive to some grass or tree pollen. These individuals can then suffer from allergies during nearly the whole year. The present study examined the prevalence of sensitization to ragweed in German children and possible health implications. METHODS Between 2004 and 2007 sera of 1323 10-years old children in Baden Württemberg were tested in-vitro for specific IgE-antibodies against common aeroallergens including ragweed pollen. RESULTS Specific IgE-antibodies to extracts of common ragweed pollen were present in 10 - 17 % of the tested sera depending on the year of investigation. CONCLUSION The determined specific IgE-antibodies may be the result of a direct sensitization to ragweed pollen or correspond to cross-reactivity to other plants of the asteraceae subfamily or some nutritional allergens. The detection of sensitization to ragweed pollen does not prove actual allergic disease. However, a ragweed derived allergy should be considered in the differential diagnosis when allergic symptoms are present in direct connection to the flowering-time of ragweed. Ragweed plants should be removed and the spread of the plant 'restricted', as experiences in other countries with already wide spreading show.

Abstract
Mucopolysaccharidoses are a family of metabolic disorders characterized by a deficiency in the catabolic lysosomal pathways. They are rare, inherited diseases which lead to progressive cellular, tissue and organ damage across a broad spectrum of phenotypes. To prevent irreversible damage early diagnosis is essential. Typical signs and symptoms are the thoracolumbar gibbus, shortened and plumped metacarpal bones, hip dysplasia, deformed ribs and ovoid vertebral bodies. Due to the typical deformation of the pelvis hip dislocation occurs often in childhood. Bilateral carpal tunnel syndrome is frequent. Bone marrow transplantation and enzyme replacement therapy are available. Orthopaedic interventions are based on individual therapeutic decisions and indications.

Abstract
BACKGROUND Flicker light is an easy method to test sensory function after stress. The aim of this study was to determine the influence of flicker stress on temporal contrast sensitivity in healthy controls and patients with glaucomatous alteration of the optic disk. METHODS A commercially available full-field stimulator (Retiport, Roland Consult) equipped with white LEDs was modified to perform psychophysical tests. The patients underwent measurements of the recovery time interval from cessation of flicker stress until recognition of a pregiven flicker contrast after photo stress. In addition, we studied contrast sensitivity with a continuous flickering target and with a flicker burst protocol avoiding adaptation to prevailing flicker. All tests were performed at a constant retinal illumination and at a frequency of 37 Hz for provocation as well as for contrast sensitivity tests. SUBJECTS Normal healthy controls (40), "preperimetric" (62), and "perimetric" (52) open-angle glaucoma patients were studied. Exclusion criteria were age lower than 31 years, visual acuity under 0.6, and perimetric mean defect more than 9.5 dB. RESULTS Recovery time after flicker stress was significantly longer in patients than in normals and longer in perimetric than in preperimetric patients. Analysis in perimetric patients revealed a larger area under ROC for the provocation test (0.95) than in contrast sensitivity tests (continuous flicker method: 0.90, flicker burst mode: 0.84). CONCLUSION High-power LEDs which are installed in modern full-field devices can be used as a helpful tool to study psychophysical properties. In the present study it could be shown that threshold, adaptation, and recovery of temporal transfer characteristics are impaired in many patients with glaucoma.

Abstract
7527 Background: Initial treatment strategies in FL include observation (obs), rituximab (R), chemotherapy ± R, and XRT. A recent study suggests initial therapy may impact FL survival (JCO 23:8447). NLCS is the first prospective observational study in the US designed to assess FL presentation, prognosis, treatment, and clinical outcomes. We describe initial therapeutic strategy in NLCS FL pts. Methods: FL pts diagnosed within 6 months with no prior lymphomas were recruited in this ongoing study. Data collected includes histology, stage, therapy, response, relapse and death. There is no specified treatment regimen. Results: From 3/04 to 11/05 1493 pts enrolled at 237 sites in the United States. Demographics have been initially reported at ASH 2005 (Blood 106:293a) and are comparable to SEER. Initial therapeutic strategy was: obs, 19%; R-monotherapy, 13%; chemo+R, 51%; XRT, 5%; chemo only, 4%. Chemo+R regimens were: R-CHOP, 59%; R-CVP, 19%; R-fludarabine based,11%; other, 11%. Choice to initiate therapy was associated with FLIPI, stage, and grade (p < 0.0001). Significant regional differences (p < 0.0001) were noted: obs was used in 13% of pts in Southeast and 31% in Northeast (NE); fludarabine-based R-chemo was used in 18% of pts in Southwest and only 3% in NE. Academic sites were more likely than community sites to treat pts on clinical trials (12% vs 4%). In pts treated with R or chemo+R, a higher FLIPI was not associated with decision to utilize chemotherapy. 26% of initially observed pts have switched to active therapy after a median of 2.8 months on obs since diagnosis; this was associated with baseline grade (III>II>I), but not stage or FLIPI. Conclusions: Diverse regimens are used for initial management of FL in the United States. Few pts are treated on clinical trials. Significant differences among regions and between center types suggest physician preference may drive initial therapy. Studies such as NLCS are needed to better understand the impact of initial therapy on short- and long-term outcomes. [Table: see text]

Abstract
BACKGROUND From 1970 to 1990 increasing rates of asthma and allergic sensitisation were observed in several countries. The aim of this study was to investigate time trends in the prevalence of asthma and allergic sensitisation among school children in Germany between 1992 and 2001. METHODS Parental reports of asthma, hay fever, and wheezing and measurements of specific serum IgE antibodies were investigated in six serial cross sectional surveys of 9-11 year old school children in three study areas in south west Germany. RESULTS A total of 6762 school children of mean age 10 years (mean participation rate 77.9%) took part in the investigation in the three study areas. Over the 9 year study period no increase in the prevalence of current wheezing and asthma was observed. In addition, the prevalence of atopic sensitisation remained unchanged during the observation period. CONCLUSIONS These data, using parental reports and objective measures of allergy, suggest that there has been no further increase in the prevalence of asthma and atopy since 1992. The epidemic may thus have reached a plateau.

Abstract
Although PCB and PCB-containing materials are not processed for a long time, PCB is under discussion again and again caused by the pollution of indoor environments. To objectify the discussion, the dates of the PCB-biomonitoring, the organochlorine-compounds (DDE, HCB, beta-/gamma -HCH, PCDD/PCDF) and the polybrominated biphenyl ethers concerning the investigations within the project "Sentinel Health Departments" in Baden-Wurttemberg are represented. Additionally results from children from Kazakhstan (Aral-Sea area) and from teachers which are working in PCB polluted schools as well as from a long term investigated test person are reported. Blood concentrations of the following compounds decreased from 1996/97 to 2002/03: the sum of the concentration of PCB 138,153 and 180 decreased from 0.46 microg/L to 0.20 microg/L, DDE from 0.32 microg/L to 0.17 microg/, HCB from 0.20 microg/L to 0.08 microg/L, beta-HCH below the level of detection, I-TEQ NATO to 4.8 pg/g blood fat, TEQ WHO (without PCB) to 5.5 pg/g blood fat, PCB 126 to 18,8,pg/g blood fat and PCB 169 to 12.8 pg/g blood fat. The influence of breast feeding and the gender on the level of the pollution is conspicious. No local correlations were found in Baden-Wurttemberg, but they were found in comparison with the results of Kazakhstan (Aral-Sea area). The difficulty to produce time series while the analyzing pollutants are more and more decreasing, as well as the change of the calculation base of the summation of parameters like I-TEQ NATO to TEQ WHO are discussed.

Abstract
So far there have been rather few reliable and comparable data available on indoor pollution with mould. Following the publication of the Federal Environmental Agency and the Health Agency Baden-Württemberg which supports the assessment of mould pollution of indoor air, it seemed advisable to investigate as to how far these criteria can be used for the assessing the mould pollution in daily practice. The results of investigations of 130 homes and 117 classrooms in Baden-Württemberg. will be represented.

Abstract
The study examined the exposure to biological indoor air agents and their possible role for allergies and respiratory tract illnesses of children. It was conducted as a case control study (atopic vs non-atopic children) at the four surveillance public health departments in Baden-Württemberg in the winter season 1999/2000 and included 379 children of the fourth class. The concentrations of the house dust mite antigens Der F1, Der p1, and Der Gr2 as well as cat allergen Fel d1 were determined in the children's bedrooms on the ground and in the mattress. Specific IgE-antibodies against allergens from house dust, mites and cat were determined in the serum of the children. For mite allergens the following medians ( micro g/g) were estimated in floor dust: Der p1 = 0.6, Der f1 = 2.3, Gr2 = 0.1; in mattresses: Der p1 = 1.2, Der f1 = 3.4, Gr2 = 0.3. The median of Fel d1 in floor dust was 0.2 microg/g, in mattresses 0.1 microg/g. Sensitisation to dust mite allergen was found to be more prevalent than sensitisation to cat. The distribution of sensitisation among the cases and controls is different. Among the cases, more subjects were sensitised to dust mites (32.9 %) and cat (13.1 %). Among the controls, 17.1 % were sensitised to dust mites and 4.1 % to cat. The results showed no direct association between the prevalence of allergies or respiratory tract illnesses and the indoor concentrations of the allergens. Possible reasons for these findings are discussed.

Abstract
Since 1992, in Baden-Württemberg, ten-year old children have been surveyed in the project "Sentinel Health Departments" to study their exposure to environmental pollutants and possible health effects. In the four study areas 1200 children have been investigated every year initially, since 1996 every second year. The data for mercury in body fluids are reported here. The decrease in the body burden of mercury as a result of the declining usage of dental amalgam fillings, was been verified. In 1992/93, of all the children who had been surveyed, the 95 percentile for the body burden of mercury was 3.1 microg/l and in 2000/01 1.35 microg/l. Also to be discussed is the reason why mercury-based cosmetic ointments seriously exceed the HBM-II-intervention-value. Because of using these ointments, concentrations of mercury in urine up to 1400 microg/l were found. A study within the project "Sentinel Health Departments" compared the concentrations of mercury in the urine of adults with those in blood and salvia. The results support the opinion that mercury in urine is appropriate for estimating the mercury uptake from dental amalgam fillings. It can be assumed that these results reflect the situation in the entire Federal Republic of Germany. The ten years' experience confirms that the concept of the "Sentinel Health Departments" is excellently suited to obtain data relevant for environmental health of children. Environmental health protection and the essential gathering of data for future health observation in Baden-Württemberg.

Abstract
BACKGROUND In Germany, where geogenic selenium concentrations are low, only few data on selenium status in children are available. Aim of the study was to investigate serum selenium concentrations of children in a population-based sample and to additionally investigate spatial and temporal differences. METHOD In three consecutive cross sectional studies the selenium concentration in serum was determined in 1,918 children (mean age 10.3 years) from four study areas. Potential factors of influence were assessed by questionnaires filled in by parents and physicians, respectively. Selenium determination was done by hydride atomic absorption spectrometry after microwave digestion. RESULTS Mean selenium concentrations for the subcollectives ranged from 54.5 +/- 10.5 micro g/l to 71.9 +/- 15.1 micro g/l. The minimum observed was 14 micro g/l, the maximum 216 micro g/l. Turkish children had lower selenium concentrations than German children and children of other nationality, respectively. Controlling for sex and year of investigation German children from Stuttgart had significantly lower selenium concentrations than children from Aulendorf/Bad Waldsee. In the same regression model for the period from 1995/96 to 1998/99 a decreasing trend was found to be significant. However, the regression model only explains a very small part of variance. CONCLUSIONS The selenium concentrations determined in this study are in the range also found in other studies in children from Germany. They are far below the toxicologically relevant range, which starts at about 600 micro g/l. The 5 th percentile in nearly all subcollectives was below the threshold limit of the lower tolerable selenium concentration of 45 micro g/l. For children from south Germany deficiency of selenium is therefore more to be suspected than a burden relevant to health. Selenium supplementation should however be considered thoroughly. Balanced nutrition is also a main factor for an optimum selenial supply.

Abstract
PURPOSE We evaluated the efficacy of topical brimonidine in visual field preservation and/or improvement in eyes undergoing controlled glaucoma. METHODS Seventy eyes of patients were trained with two different visual field test strategies: The Octopus Tendency Oriented Perimetry (TOP) G1 and the Frequency Doubling Technology (FDT) 30 degrees. Following 2-4 months of brimonidine treatment, there were significant improvements in visual field, as assessed using the TOP G1 strategy (p = 0.003). The FDT 30 degrees test revealed no statistically significant differences. CONCLUSIONS These data support the results of other studies, which indicate that brimonidine may increase mean sensitivity in visual field tests. Since it is known that the control of intraocular pressure does not fully protect glaucomatous eyes from visual field loss, it is possible that the neuroprotective qualities of brimonidine may contribute to visual field preservation in glaucomatous eyes.

Abstract
The rare case of a 3.5 month-old infant diagnosed with a endobronchial haemangioma is presented and discussed against a background of reference literary material. A main-bronchus sleeve resection with end-to-end anastomosis was performed without reduction of lung parenchyma. No complications were documented during the period of observation. The results of repeated bronchoscopy showed the post-operative period to be of a non-problematic nature.

Abstract
Waldenstrom's macroglobulinemia (WM, lymphoplasmacytic lymphoma) is a B-cell lymphoproliferative disorder in which CD20 is expressed on tumor cells from most patients. Several small studies have suggested a benefit from the anti-CD20 monoclonal antibody rituximab (Rituxan, MabThera) in patients with WM. In this retrospective study, we examined the outcome of 30 previously unreported patients with WM who received treatment with single-agent rituximab (median age 60; range 32-83 years old). The median number of prior treatments for these patients was 1 (range 0-6), and 14 patients (47%) received a nucleoside analogue before rituximab therapy. Patients received a median of 4.0 (1-11.3) infusions of rituximab (375 mg/m2). Three patients received steroids with their infusions for prophylaxis of rituximab-related infusion syndrome. Overall, treatment was well tolerated. Median immunoglobulin M (IgM) levels for all patients declined from 2,403 mg/dL (range 720-7639 mg/dL) to 1,525 mg/dL (range 177-5,063 mg/dL) after rituximab therapy (p = 0.001), with 8 of 30 (27%) and 18 of 30 (60%) patients demonstrating >50% and >25% decline in IgM, respectively. Median bone marrow lymphoplasmacytic (BM LPC) cell involvement declined from 60% (range 5-90%) to 15% (range 0-80%) for 17 patients for whom pre- and post-BM biopsies were performed (p < 0.001). Moreover, 19 of 30 (63%) and 15 of 30 (50%) patients had an increase in their hematocrit (HCT) and platelet (PLT) counts, respectively. Before rituximab therapy, 7 of 30 (23.3%) patients were either transfusion or erythropoietin dependent, whereas only 1/30 (3.3%) patients required transfusions (no erythropoietin) after rituximab. Overall responses after treatment with rituximab were as follows: 8 (27%) and 10 (33%) of the patients achieved a partial (PR) and a minor (MR) response, respectively, and an additional 9 (30%) of patients demonstrated stable disease (SD). No patients attained a complete response. The median time to treatment failure for responding (PR and MR) patients was 8.0 months (mean 8.4: range 3-20+ months), and 5.0 months (mean 6.1; range 3-12+ months) for patients with SD. These studies therefore demonstrate that rituximab is an active agent in WM. Marked increases in HCT and PLT counts were noted for most patients, including patients with WM who had MR or SD. A prospective clinical trial to more completely define the benefit of single-agent rituximab in patients with WM has been initiated by many of our centers.

Abstract
A 3-month-old female child suffered from tachypnea and dyspnea with abnormal blood gas values. Chest X-rays revealed an increased transparency of the left lung and a mediastinal shift to the right side. High resolution computed tomography (CT) documented a narrowing of the left upper stem bronchus. Ensuing endoscopy detected an occlusive endobronchial tumor mass that did not infiltrate the bronchial cartilage as confirmed with endobronchial ultrasonic monitoring. Based on gross histological examination of the surgical specimen obtained using sleeve resection, the highly vascularized tumor exhibited an adenomatoid growth pattern with a rather homogeneous population of nuclei. The light microscopical presentation was consistent with a juvenile (infantile) hemangioma, which was confirmed using immunohistochemical examinations despite the display of neuroendocrine features. Although endobronchial juvenile hemangiomas are an extremely rare event in early childhood, this case underscores the necessity to not neglect its occurrence in differential diagnosis.

Abstract
In order to get more information about potential health hazards due to indoor air PCBs the present study investigated the PCB indoor concentration in schools as well as the blood levels of 6 PCB-indicator congeners in teachers from these schools. 151 teachers (78 male and 73 female; mean age 48 years) from 3 contaminated and 2 control schools participated in the study. Maximal indoor air values for total PCBs (6 PCB-indicator congeners times 5) in schools ranged from 1587 to 10655 ng/m3. Blood analyses indicated an increase in mean PCB 28 level from 0.036 (control group) to 0.098 microg/l in teachers from a school with heavy contamination of low chlorinated PCB. But there was no significant increase of PCB 138, 153 and 180 in blood above the normal background concentrations in any of the contaminated schools (mean values of all groups: PCB 138 = 0.66, 153 = 0.95, 180 = 0.70 microg/l blood). The results of blood analyses and additional toxicokinetic calculations suggested that inhalative PCB-uptake in the most contaminated schools caused a minor increase above mean background-PCB concentrations in blood. In conclusion, despite high PCB indoor air levels in schools, there was only a moderate increase in blood concentrations of teachers, mainly due to congeners with low chlorination (PCB 28 to PCB 101).

Abstract
Family-aided assertive community treatment (FACT) was enhanced by adding vocational specialists to help persons with severe mental illness obtain competitive employment. Results were then tested against those of conventional vocational rehabilitation (CVR). The FACT cohort demonstrated significantly better employment rates than did the CVR, while negative symptoms declined in the former and increased in the latter. No evidence was found that competitive work presented a significant risk for relapse.

Abstract
To assess the preliminary efficacy of rituximab therapy in Waldenstrom's macroglobulinemia (WM), we examined the clinical and laboratory data for all patients with WM treated on IDEC Pharmaceuticals sponsored trials and one patient treated at Walter Reed Army Medical Center. Seven symptomatic patients with WM were treated with four (n = 6) or eight (n = 1) weekly infusions of rituximab (375 mg/m2). Patients had received a median of three prior therapies (range 1-4) which included alkylator therapy in all (five patients refractory) and fludarabine in four (all refractory). Therapy was tolerated well in all patients without decrement in cellular immune function or significant infectious morbidity. Partial responses were noted in three of these patients, including two with fludarabine-refractory disease. The median progression-free survival for these patients was 6.6 months (range 2.2-29+ months). These data suggest that rituximab has clinical activity in heavily pre-treated patients with Waldenstrom's macroglobulinemia. Based on these data, clinical studies of Rituximab in previously untreated and treated WM appear indicated.
