Abstract
In 2021, a national network of multidisciplinary medical competence-centers has established itself in Germany that is committed to ensuring the care of people with thalidomide embryopathy. This article would like to draw attention to this competence network and give an overview of the most important medical care needs of aging people with thalidomide-induced body and sensory impairments. Here, the available scientific evidence and clinical peculiarities in medical care from a general medical-internal, orthopedic-paintherapeutic, sociomedical and psychosomatic-psychotherapeutic perspective will be presented and necessary tasks for the future will be discussed.

Abstract
OBJECTIVE The aim of the study was to show the frequency, localisation, intensity, quality and degree of chronic pain in people with thalidomide-induced congenital defects (thalidomide embryopathy) and to investigate the association with biopsychosocial factors more closely. METHODS A group of 202 people from North Rhine-Westphalia with thalidomide embryopathy were studied for the first time both physically for the pattern of the original damage and also psychiatrically in a structured diagnostic interview (SCID I & SCID II). The results were combined with a standardized pain interview (MPSS) and questionnaires on further pain-related (SF-36, painDETECT) and sociodemographic variables and analysed. In the analysis 167 completed datasets were included. RESULTS The prevalence of pain in the sample population was 94%. The majority (107, 54.0%) already showed an advanced stage of chronicity in the MPSS: 63 subjects with Stage II (37.7%) and 44 with Stage III (26.3%). In 74 subjects (44.3%) the PainDetect score showed a possible or neuropathic pain component. The factors that most reliably influenced the chronicity of pain proved to be hip pain (p<0.001) and also mental health disorders (p=0.001), above major depression (p<0.001) and also somatic symptom disorders and substance-related disorders (p=0.001 in each case). Social variables proved non-significant here (p=0.094 for living alone, p=0.122 for unemployment, p=0.167 for lack of college education), as did the care situation (p=0.191 for care dependency) and the underlying pattern of organ damage (p=0.229 for damage to hearing, p=0.764 for dysmelia). CONCLUSIONS People with thalidomide defects frequently suffer from a separate pain disorder which can be seen as secondary thalidomide-induced damage and which requires specialized and personalized multimodal pain management.

Abstract
The update of the German S3 guideline on atraumatic femoral head necrosis in adults aims to provide an overview of diagnosis and treatment. All clinical studies, systematic reviews, and meta-analyses published in German or English between 01.05.2013 and 30.04.2017 were included. Of 427 studies, 28 were suitable for analysis. Risk factors are corticosteroids, chemotherapy, kidney transplants, hemoglobinopathies, and alcoholism. Differential diagnoses are for example bone marrow edema, insufficiency fracture, and destructive arthropathy. Radiography should be performed upon clinical suspicion. In patients with normal radiography findings but persistent complaints, magnetic resonance imaging (ARCO classification) is the method of choice. Computed tomography (CT) can be used to confirm/exclude articular surface collapse. A subchondral sclerosis zone >30% in CT indicates a better prognosis. Left untreated, a subchondral fracture will develop within 2 years. The risk of disease development in the opposite side is high during the first 2 years, but unlikely thereafter. In conservative therapy, iloprost and alendronate can be used in a curative approach, the latter for small, primarily medial necrosis. Conservative therapy alone as well as other drug-based and physical approaches are not suitable for treatment. No particular joint-preserving surgery can currently be recommended. Core decompression should be performed in early stages with <30% necrosis. From ARCO stage IIIc or in stage IV, the indication for total hip arthroplasty should be checked. Results after total hip arthroplasty are comparable with those after coxarthrosis, although the revision rate is higher due to the relatively young age of patients. Statements on the effectiveness of cell-based therapies such as expanded stem cells or bone marrow aspirates cannot currently be made.

Abstract
Zusammenfassung. Hintergrund: Zwischen 1957 und 1962 wurden in Deutschland ca. 5000 sogenannte Contergan-Kinder geboren, deren Mütter während der Schwangerschaft das Beruhigungs- und Schlafmittel Contergan genommen hatten. Fragestellung: Das Ziel der Studie war es, die pflegerische Versorgung, ungedeckte Bedarfe und finanzielle Eigenleistungen vor dem Hintergrund der Conterganschädigung mit ihren spezifischen Ausprägungen bei einzelnen Betroffenen sowie eventuelle zukünftige Herausforderungen zu erheben. Methoden: Es wurde eine Befragung mittels Fragebogen zu der pflegerischen Versorgung, den Bedürfnissen und vorliegenden Pflegestufen durchgeführt. Außerdem gab es eine orthopädische und psychische Untersuchung der Betroffenen hinsichtlich ihrer körperlichen Behinderungen und Beeinträchtigungen sowie psychischer Störungen. Ergebnisse: Die Contergangeschädigten teilen sich bezüglich ihrer pflegerischen Bedürfnisse in zwei Gruppen: Personen mit und ohne Beeinträchtigungen der Extremitäten. Das Vorhandensein des pflegerischen Bedarfes und die dafür aufgewendeten privaten Mittel verlaufen entlang dieser Grenze. Viele der Betroffenen werden nur von ihrem sozialen Umfeld pflegerisch betreut, was eine eigene Problematik darstellt, da das Umfeld der Betroffenen mitaltert und sie teilweise sogar noch von ihren Eltern versorgt werden. Schlussfolgerungen: Die Prävalenz für die Pflege bei Contergangeschädigten ist höher als in der deutschen Allgemeinbevölkerung derselben Altersgruppe, professionelle Pflegedienstleister sind unterrepräsentiert. Diese sollten häufiger in Anspruch genommen werden und dem spezifischen Bedarf der Betroffenen gerecht werden.

Abstract
Background Between 1957 and 1961 the substance Thalidomide was sold in West Germany and taken by many women as a sedative during pregnancy. This lead to miscarriages and infants been born with several severe malformations. The aim of this study was to describe the current situation of women impaired by Thalidomide induced embryopahty in North Rhine-Westphalia (Nordrhein-Westfalen), Germany, in comparison with the results found in a study done in 2002 by Nippert et al. Methods Questionnaires as well as examinations were performed. Data were compared using descriptive and inductive statistical methods. Results Both studies show that women impaired by Thalidomide embryopathy face a poorer health status than women their age in the general population and live in fear of further deteriorating health. The majority can only work reduced hours or are already retired due to poor health. Most of those who need assistance are being assisted by their social environment, while professional care is still utilized in only few cases. Conclusions An obvious need for a shift in the provision of assistance and/or care provided was found as the social environment supporting the impaired women is also aging and therefore in high danger of breaking apart. Trial registration The study has been registered at German Clinical Trials Register, DRKS00010593, on 07.06.2016 retrospectively.

Effects of ovarian fluid and genetic differences on sperm performance and fertilization success of alternative reproductive tactics in Chinook salmon. J Evol Biol 2017; 30:1236-1245.

Abstract
In many species, sperm velocity affects variation in the outcome of male competitive fertilization success. In fishes, ovarian fluid (OF) released with the eggs can increase male sperm velocity and potentially facilitate cryptic female choice for males of specific phenotypes and/or genotypes. Therefore, to investigate the effect of OF on fertilization success, we measured sperm velocity and conducted in vitro competitive fertilizations with paired Chinook salmon (Oncorhynchus tshawytscha) males representing two alternative reproductive tactics, jacks (small sneaker males) and hooknoses (large guarding males), in the presence of river water alone and OF mixed with river water. To determine the effect of genetic differences on fertilization success, we genotyped fish at neutral (microsatellites) and functional [major histocompatibility complex (MHC) II ß1] markers. We found that when sperm were competed in river water, jacks sired significantly more offspring than hooknoses; however, in OF, there was no difference in paternity between the tactics. Sperm velocity was significantly correlated with paternity success in river water, but not in ovarian fluid. Paternity success in OF, but not in river water alone, was correlated with genetic relatedness between male and female, where males that were less related to the female attained greater paternity. We found no relationship between MHC II ß1 divergence between mates and paternity success in water or OF. Our results indicate that OF can influence the outcome of sperm competition in Chinook salmon, where OF provides both male tactics with fertilization opportunities, which may in part explain what maintains both tactics in nature.

Abstract
INTRODUCTION The treatment of adult non-traumatic avascular necrosis of the femoral head (AVN; N-ANFH) within an estimated incidence of 5000-7000 cases per annum in Germany remains a challenge. Risk factors include steroids, alcohol abuse, chemotherapy and immunosuppressive medication, but a genetic predisposition has been suggested. Early diagnosis of this often bilateral disease process is essential for successful conservative or joint preserving surgical management. In this review, we present the update German consensus S3 guideline "diagnosis and management for N-ANFH" as a concise summary. MATERIALS AND METHODS This systematic review is based on the published literature from January 1, 1970 to April 31, 2013 (German and English language). Inclusion criteria were systematic reviews, meta-analyses and relevant peer review publications. We identified a total of 3715 related publications, of which 422 were suitable according to the SIGN criteria, but only 159 fulfilled our inclusion criteria. RESULTS AND CONCLUSIONS Clinical suspicion of N-ANFH mandates radiographic evaluation. If radiographs are normal MRI scans are recommended, which should be evaluated according to the ARCO-classification. Differential diagnoses include transient osteoporosis, bone bruise, insufficiency fracture and destructive arthropathy. Untreated, subchondral fractures commonly occur within 2 years, during which the risk for contralateral involvement is high-thereafter unlikely. Conservative management with Ilomedin and Alendronat can be tried, but other pharmacological or physical treatments are inappropriate. No specific joint preserving procedure can be recommended, but core decompression should be considered in early stages if necrosis is <30 %. In ARCO stages IIIc or IV total hip arthroplasty (THA) should be contemplated, which offers similar outcome compared to osteoarthritis. Young age is the main risk factor for higher revision rates after THA for N-ANFH.

Abstract
BACKGROUND The treatment of fracture nonunion (pseudarthrosis) is often lengthy and debilitating for the patient. There are operative and conservative therapies available. RESEARCH QUESTION Does the systemic use of osteoanabolic acting substances (osteoanabolics) lead to an acceleration of the delayed fracture healing and/or strengthening of the fracture? Which types of pseudarthrosis are suitable for this treatment option? MATERIALS AND METHODS A literature review was carried out focusing on the systemic anabolic therapy options for the treatment of delayed healing of fractures or pseudarthrosis. Additionally, our own case studies are presented. RESULTS Teriparatide and strontium ranelate have a positive effect on the healing of fractures in animal studies and in humans. There are also case studies on the use of both substances in delayed fracture healing or pseudarthrosis. The scientific knowledge regarding teriparatide is significantly more comprehensive. However, prospective randomized trials are lacking so far. CONCLUSION The systemic use of anabolics can be a therapeutic option, especially for biological reactive pseudarthrosis. However, these are off-label treatments and contraindications should be especially well heeded. Because of the numerous positive results, from the point of view of teriparatide treatment, a multicentric, prospective randomized study on the treatment of aseptic pseudarthrosis should be initiated.

Abstract
BACKGROUND In the literature many studies can be found addressing the effectiveness of individual measures and therapies within the medical rehabilitation. The duration of the rehabilitation itself is rarely taken into account. Consequently the duration of postoperative inpatient medical rehabilitation after initial implantation of alloarthroplastic hip and knee replacements in osteoarthritis of the hip or knee was the object of our analysis. PATIENTS AND METHODS In the present prospective study 100 patients each with osteoarthritis of the hip or knee were presented at a follow-up treatment postoperatively after primary implantation of alloarthroplastic hip and knee replacements. Two different scores were used (Staffelstein score, Lequesne score), which were collected at a weekly follow-up (T1-T4) to determine the degree of mobility in the initial examination of the patient and after three weeks. By setting a target score at admission of the patient to the CSO, which stood for achieving the rehabilitation objective, the rehabilitation period could be changed individually. RESULTS Our study showed that the highest rehabilitation progress has been achieved in both the total hip replacement and total knee replacement in patients at the end of the second week of rehabilitation (T2-T3). Thus, in the Staffelstein score 74 % (n = 74) of hip replacement patients and 46 % (n = 46) of knee replacement patients had already reached their rehabilitation aim between T2 and T3. From the third week on there was a marked flattening of the rehabilitation progress. Also the Lequesne scores obtained confirmed these results. CONCLUSION Based on the score-driven detection of mobility degree of rehabilitation at the beginning of the follow-up treatment, the individual design of the rehabilitation process with the active participation of the patient is possible. In a large number of cases a reduction of the rehabilitation period can be achieved to less than 21 days. This finding is particularly important in times of limited financial resources, because the saved resources can be used for other rehabilitation groups. Therefore, in a greater number of patients, a shortening of the duration of the rehabilitation is possible.

Abstract
PURPOSE We determined the efficacy and safety of pelvic floor myofascial physical therapy compared to global therapeutic massage in women with newly symptomatic interstitial cystitis/painful bladder syndrome. MATERIALS AND METHODS A randomized controlled trial of 10 scheduled treatments of myofascial physical therapy vs global therapeutic massage was performed at 11 clinical centers in North America. We recruited women with interstitial cystitis/painful bladder syndrome with demonstrable pelvic floor tenderness on physical examination and a limitation of no more than 3 years' symptom duration. The primary outcome was the proportion of responders defined as moderately improved or markedly improved in overall symptoms compared to baseline on a 7-point global response assessment scale. Secondary outcomes included ratings for pain, urgency and frequency, the O'Leary-Sant IC Symptom and Problem Index, and reports of adverse events. We compared response rates between treatment arms using the exact conditional version of the Mantel-Haenszel test to control for clustering by clinical center. For secondary efficacy outcomes cross-sectional descriptive statistics and changes from baseline were calculated. RESULTS A total of 81 women randomized to the 2 treatment groups had similar symptoms at baseline. The global response assessment response rate was 26% in the global therapeutic massage group and 59% in the myofascial physical therapy group (p=0.0012). Pain, urgency and frequency ratings, and O'Leary-Sant IC Symptom and Problem Index decreased in both groups during followup, and were not significantly different between the groups. Pain was the most common adverse event, occurring at similar rates in both groups. No serious adverse events were reported. CONCLUSIONS A significantly higher proportion of women with interstitial cystitis/painful bladder syndrome responded to treatment with myofascial physical therapy than to global therapeutic massage. Myofascial physical therapy may be a beneficial therapy in women with this syndrome.

Abstract
INTRODUCTION Osteoporosis is the most common generalized disease of the skeleton, yet it is markedly undertreated in Germany. METHODS Selective literature review on the basis of the current German guidelines regarding the prevention, diagnosis, and treatment of osteoporosis in postmenopausal women and in men aged 60 and above, and a further search of literature published in the last three years. RESULTS AND DISCUSSION The indication for dual X-ray absorptiometry (DXA) measurement for the specific diagnosis of osteoporosis is derived from the patient's age, sex, history of fractures in the past, and further risk factors. The therapeutic threshold for osteoporosis has been set at a 30% predicted risk of osteoporotic fractures occurring within 10 years. The treatment consists of basic measures for fracture prevention combined with specific pharmacotherapy. The recommended drugs for the treatment of osteoporosis in postmenopausal women in particular are alendronic and ibandronic acid, raloxifen, risedronic acid, and strontium ranelate; the only approved drugs for men at present are alendronic and risedronic acid and teriparatid. Intensive patient education markedly improves the otherwise poor compliance with osteoporosis treatment.

Abstract
Non-infective inflammations of the vertebral spine can be caused by seronegative spondylarthropathies or rheumatoid arthritis, respectively. Seronegative spondylarthropathies include ankylosing spondylitis, psoriatic arthritis, reactive arthritis, arthritis associated with inflammatory bowel diseases and undifferentiated arthritis. This review discusses etiology and pathogenesis, epidemiology, clinical features, diagnosis and differential diagnoses of these chronic inflammatory diseases with a special focus on vertebral involvement.

Abstract
OBJECTIVES To evaluate the responsiveness of composite scales to change over time in a clinical trial of patients with interstitial cystitis (IC). The measurement of symptoms in IC includes the O'Leary-Sant Symptom and Problem Indexes and the University of Wisconsin Interstitial Cystitis Inventory and scales that measure the individual symptom domains of pain/discomfort, urgency, and voiding frequency. METHODS The data were derived from a randomized clinical trial conducted by the Interstitial Cystitis Clinical Trials Group. Participants met the National Institutes of Health-National Institute for Diabetes, and Digestive and Kidney Diseases criteria for IC and reported at least moderate pain and frequency. The primary endpoint was a patient-reported global response assessment (GRA) at 24 weeks. Secondary endpoints included the three composite indexes, pain/discomfort and urgency, and 24-hour frequency. Responsiveness was assessed by comparing symptom score changes against response categories defined by the GRA. RESULTS Of the 121 subjects in the original trial, 94 with complete data were included. All three composite indexes were sensitive to subject improvement over time as measured by the GRA. A 1.2-point change in the O'Leary-Sant indexes and a 3.1-point change in the Wisconsin IC inventory corresponded to a one-category change in the GRA. Individual symptoms were also responsive. The correlation was high among the changes in the six outcome measures. CONCLUSIONS The three composite symptom scales are responsive to change over time in patients with IC. These indexes provide important insight into symptom changes and are recommended as secondary endpoints in future clinical trials of IC. Additional endpoints addressing individual symptom domains should also be considered to aid in the evaluation of effect mechanisms.

Abstract
To determine if a relationship exists between patient body habitus and urinary incontinence after radical retropubic prostatectomy (RRP) for clinically localized prostate cancer. A questionnaire developed by combining parts of lower urinary tract symptom questionnaires concerning voiding symptoms after RRP was mailed to 268 consecutive patients who underwent RRP over a 2-year period. The interval between surgery and questionnaire administration was greater than 24 months for each patient. No interval was greater than 54 months. The questionnaire attempted to overcome the subjectivity of patient documented urinary incontinence by probing different aspects of each patient's voiding symptoms. Body mass index (BMI), obtained from preoperative anesthesia records, was used as the measurement for body habitus. Pearson correlations were used to determine relationships between BMI and responses and the independent t-test was used to determine differences between grouped responses and BMI. One hundred and eighty-two of 268 (68%) questionnaires were returned. No relationship was detected between BMI and patient estimates of urinary control, QOL relating to urinary symptoms, severity of stress incontinence, or use of protection (pad use). As well, no statistically significant relationship was found between BMI and a patient's willingness to undergo RRP again, based on his voiding symptoms, if given the choice. In conclusion, although patient body habitus may be related to other clinical outcomes following RRP, there does not appear to be a relationship of BMI to post-RRP urinary incontinence.

Abstract
OBJECTIVE To assess the efficacy of long-term sacral neuromodulation (InterStim(R), Medtronic Inc., Minneapolis, MN) in treating chronic pelvic pain associated with interstitial cystitis (IC, a symptom complex of urinary urgency, frequency and pelvic pain, often necessitating narcotics) refractory to standard therapy. PATIENTS AND METHODS Twenty-one patients (17 female, four male, mean age 45.5 years, range 17-68) with refractory IC with chronic pelvic pain were reviewed retrospectively. In these patients a mean of six previous treatments for IC had failed. All patients had had cystoscopy and hydrodistension to confirm their diagnoses. All had a permanent InterStim device implanted by one surgeon (K.M.P.) between 2000 and 2002, after responding to a temporary test. Data were collected from chart reviews and patient questionnaires. Intramuscular morphine dose equivalents (MDEs) were calculated before and after implantation. RESULTS All 21 patients responded to the questionnaire; the mean (range) follow-up after implantation was 15.4 (7.4-23.1) months. Eighteen patients used chronic narcotics before the InterStim and 20 reported moderate or marked improvement in pain afterward. The mean MDE decreased from 81.6 to 52.0 mg/day (36%) after implantation (P = 0.015). Four of 18 patients stopped all narcotics after InterStim implantation. CONCLUSIONS Sacral neuromodulation decreases narcotic requirements and subjective pelvic pain in patients with refractory IC. Further decreases in MDE are anticipated as dose reductions continue in patients who improved.

Abstract
AIM The sonographic early diagnosis of heterotopic ossifications after total hip replacement. MATERIAL AND METHOD 53 patients were sonographically and radiologically examined after a total hip-replacement. RESULTS. In the sonographic exam,positive findings were shown in 49.1% (n=26) one week, 66% (n=35) three weeks,73.6% (n=39) six weeks and 77.3% (n=41) twelve weeks after surgery. 88.5% of patients showing positive results in the sonographic exam carried out one week after surgery, later on showed positive x-ray findings (p<0.001). Of the three-week positive x-ray findings (n=19), 78.9% had condensations in the sonographic exam (p<0.001). CONCLUSIONS Sonographic imaging after hip-replacement seems to be a sensitive and specific method which allows an early diagnosis of ossifications one week after surgery in 2/3 of patients. In this context a therapy concept which helps avoiding the development ossifications would be welcome.

Abstract
A safe differentiation of fibrodysplastic lesions from "real" bone tumours is of high importance because a fibrous dysplasia often requires no further therapy. While polyostotic involvement of fibrous dysplasia can be safely diagnosed before therapy, in monostotic disease differential diagnostic problems may occur. In the present investigation only in 6 of 14 mon- and biostotic lesions caused by fibrous dysplasia a correct diagnosis could be established by radiologic methods. However, in all cases of fibrous dysplasia malignancy could be excluded by radiology and the false diagnosis had no therapeutic consequences.

Abstract
Close cooperation between acute and rehabilitation clinics are an exception even today. Although operative reconstruction may have been successful, hand injuries will have poor functional results if rehabilitation is insufficient. With the establishment of multi-disciplinary intensive rehabilitation of patients with complex hand injuries under inpatient conditions, a close cooperation of the Clinic of Plastic and Hand Surgery, Klinikum Wuppertal, and the Orthopaedic Clinic, Rhein-Sieg-Klinik Nümbrecht, was created. A good functional outcome of the injured hands with a low percentage of remaining invalidity and an early return to work of the affected patients are the dominant aims of this rehabilitation model. When the initial and reconstructive treatment is finished in the Clinic of Plastic and Hand Surgery, inpatient rehabilitation by an experienced rehabilitation team starts immediately. Clinical control of all patients with complex hand injuries is performed in a weekly consultation hour by the hand surgeons and the rehabilitation team. Weekly reports guarantee close and timely documentation of the clinical course. After the end of inpatient rehabilitation, patients return to work, take part in vocational rehabilitation or, if necessary, continue with ambulant treatment organized and controlled by the acute clinic.

Abstract
Bilateral ruptures of patellar tendon are a rare event and occur mainly in older patients suffering from systemic diseases like lupus erythematosus, chronic renal failure, rheumatoid arthritis or are taking longterm corticosteroids. Only few cases of spontaneous bilateral rupture of patellar tendon without underlying systemic disease are described in literature up to now. This report provides a patient with bilateral patellar tendon rupture, where in further check up and follow up only a mild diabetes mellitus treated by diet could be detected as systemic disease. In current opinion diabetes mellitus does not belong to the "typical" underlying systemic diseases for tendon ruptures. In literature research diabetes mellitus was only mentioned once together with a bilateral patellar tendon rupture.

Abstract
PURPOSE Evaluation of functional outcome and socio-economic results of patients with complex hand injuries after inpatient rehabilitation. PATIENTS AND METHODS In a prospective investigation 36 patients with complex hand injuries received an intensive therapy regime under inpatient conditions. In all patients functional parameters of the hand (total active range of motion, palm to palm distance, spread between thumb and index finger, spread between thumb and little finger) and the score of Buck-Gramcko were registered initially and at the end of inpatient rehabilitation. Socio-economic data (kind of discharge, job reintegration, further treatment) were documented as well. RESULTS The total active range of motion could be improved from 36% to 69%, spread D1-D5 from 18.5 to 20.7 cm and spread D1-D2 from 13.9 to 15.6 cm. The palp to palm distance of all fingers was reduced from 4.6 cm to 2.3 cm. The Buck-Gramcko score of all injured fingers improved from 4.2 points (poor) at admission, to 11.8 points (good) at discharge, At the end of inpatient rehabilitation 18 patients could return to their job either gradually or on full-time. CONCLUSION Even patients with complex hand injuries, good functional results could be achieved by an intensive inpatient rehabilitation characterised by close medical supervision and guidance and tight clinical controls.

Abstract
OBJECTIVES To obtain preliminary urinary cytokine data on subjects with active interstitial cystitis (IC), subjects with IC in remission after bacille Calmette-Guérin (BCG), and control (non-IC) subjects. IC is a severe, debilitating bladder disease of unknown etiology and no cure. In controlled clinical trials, intravesical BCG has been shown to be an effective and durable treatment for IC. The durability of this treatment led us to speculate on the mechanism by which intravesical BCG may treat IC. Evidence exists that IC may be mediated by an abnormal immune profile within the bladder. Intravesical BCG is known to stimulate the immune system of the bladder. METHODS Fresh voided urine was collected from 15 subjects with active IC, 9 subjects with IC who received intravesical BCG and had been in remission for an average of 2.6 years, and 11 non-IC subjects. The urine was immediately centrifuged, aliquoted, and frozen in liquid nitrogen. At the time of urine collection, a validated IC questionnaire was completed. The enzyme-linked immunosorbent assay technique was used to determine levels of urinary cytokines interleukin (IL)-2, IL-4, IL-6, IL-8, IL-10, IL-12, tumor necrosis factor (TNF), human granulocyte-macrophage colony stimulating factor (hGM-CSF), IL-1beta, and interferon-gamma (IFN-gamma). RESULTS Cytokines IL-4, IL-10, IL-12, TNF, hGM-CSF, IL-1beta, and IFN-gamma were not detected. Significant elevations in symptom scores and IL-2, IL-6, and IL-8 were found in the urine of subjects with active IC compared with subjects with IC in remission and control subjects. The urinary cytokine levels and symptom scores were identical in the IC group who had received BCG and the control group. CONCLUSIONS Elevations in symptom scores and urinary cytokine levels were seen in subjects with active IC, suggesting an abnormal immune profile in this disease. Subjects with IC in remission after receiving BCG had identical cytokine levels and symptom scores as non-IC control subjects. Intravesical BCG may be effective in treating IC by correcting an aberrant immune imbalance in the bladder, leading to long-term symptomatic improvement. A prospective study is ongoing to further investigate the role of the immune system in IC.

Abstract
PURPOSE Interstitial cystitis is a severe debilitating bladder disease characterized by unrelenting pelvic pain and urinary frequency. A prospective, double-blind, placebo controlled study of the use of intravesical bacillus Calmette-Guerin (BCG) in the treatment of interstitial cystitis was recently completed with a mean followup of 8 months. Results demonstrated a 60% BCG response rate, compared to a 27% placebo response rate. We now report the long-term followup results of those patients who received intravesical BCG. MATERIALS AND METHODS Subjects randomized to receive BCG were followed at routine intervals with questionnaires and voiding diaries identical to those in the blinded study. Adverse events were closely monitored in the treatment and followup phases of the study. Subject baseline values were compared to followup data. RESULTS Of the BCG responders mean followup was 27 months (range 24 to 33), and 8 of 9 (89%) continue to have an excellent response in all parameters measured. The global interstitial cystitis survey improved 70%, daily voids decreased 31%, nocturia improved 54%, mean voided volume increased 61%, pelvic pain decreased 81%, vaginal pain decreased 71%, urgency decreased 71% and dysuria decreased 82%. Overall well-being improved 54% and the Rand-36 quality of life survey overall improved 64%. In 86% of the patients (6 of 7) dyspareunia resolved. Of the initial BCG nonresponders there was no significant difference in interstitial cystitis symptomatology from baseline to last followup, suggesting that BCG does not worsen interstitial cystitis symptoms. No long-term adverse events from BCG were noted. CONCLUSIONS Intravesical Tice BCG is safe, effective and durable in the treatment of interstitial cystitis. Of those patients who received only 6 weekly treatments and responded favorably 89% continue to have an excellent response with followup ranging from 24 to 33 months.

Abstract
PURPOSE A psychometric analysis of the University of Wisconsin Interstitial Cystitis Scale was conducted on 30 females previously enrolled in a phase II double-blind randomized controlled trial evaluating the efficacy of six weekly intravesical instillations of TICE BCG. The analyses were to: (1) evaluate the adequacy of the seven individual IC component items for measuring the range of patient responses; (2) verify the 2-factor (IC versus reference) construct of the scale; (3) evaluate the internal consistency and reliability of the IC items; (4) better define the scale's applicability and limitations; and (5) if possible, make recommendations for improvements in the scale. MATERIALS AND METHODS Standard psychometric analyses were used to perform the evaluation, and included descriptive analysis of individual items, computing of item-total correlations and Cronbach's internal consistency measures, and the application of factor and Rasch analyses. RESULTS The original 7-item IC scale was found to have ceiling effects that could limit its use in detecting small therapeutic differences. It was also found that the Pelvic item originally assigned to the reference set of items of the scale should be included as an IC item when used in a comparable IC population. After including this item into the IC scale Cronbach's alpha was 0.84, compared with 0.82. CONCLUSIONS The UW-IC Scale has psychometric properties similar to other measurement instruments used in clinical research, and appears worthy of further study in well-characterized IC populations. The reference items suggest that IC patients do not indiscriminately report high values for generalized body complaints, but do so on bladder related symptoms as recorded by the IC items of the scale. Although the scale has limitations it appears applicable for use in future IC intervention clinical trials.

Abstract
PURPOSE Traditional teaching in urology has been to avoid electrosurgical devices in penile surgical procedures. In the last several years cutting current has been routinely used on the penis for making skin incisions, degloving, creating Byars flaps and destroying skin bridges. The purpose of this study was to determine the complications and final outcomes of electro-surgery. MATERIALS AND METHODS A 5-year retrospective chart review was done to determine the complications and final outcomes of exclusively using electrical current to perform pediatric penile procedures. RESULTS Electrosurgery was used to perform the entire surgical dissection in 346 patients, including circumcision in 124, repeat circumcision in 68, penoscrotal fusion/chordee repair in 127 and skin bridge procedures in 27. All patients had a satisfactory cosmetic result. After correction of penoscrotal fusion, separation at the scrotal suture line in 2 patients healed secondarily without sequelae. There was no hematoma, tissue necrosis or skin sloughing and all surgery was performed on an outpatient basis. CONCLUSIONS Electrosurgery can be used safely and effectively for routine penile procedures, providing a bloodless operative field and excellent cosmetic results.

Abstract
During total hip replacement, identifiable myocardial ischemia occurs intraoperatively, indicating myocardial strain. Coronary heart disease (CHD) patients are at risk during this type of surgery. Perioperatively, CHD patients had significantly longer ST depressions than patients not suffering from CHD (3348 min vs 454 min). The number of depression episodes was also significantly higher for CHD patients (160 vs 36). Comparing the perioperative with the postoperative stage demonstrated that CHD patients experienced a highly significant shift towards shorter periods of ST-segment depression postoperatively.

Abstract
Early diagnosis of nontraumatic avascular necrosis of the femoral head has been much improved by introduction of magnetic resonance imaging (MRI). Intertrochanteric osteotomies are dominating in operative treatment of advanced necrosis of the femoral head. Studies concerning with long-term results are rare in literature. The aim of the present study was the assessment of the long-term results (> 10 years) of advanced avascular necrosis (n = 33 hips, 8 stage Ficat II, 19 stage Ficat III, 6 stage Ficat IV). In 29 cases of joint-preserving operation was primarily performed. The average follow up time of the patients was 13 years. In 13 patients a joint-destructive operation (total hip replacement or arthrodesis) was secondarily necessary. The average time interval between joint-preserving and -destructive operation was 53 months (minimal 10, maximal 180 months). Quality of life is often reduced in patients after joint-preserving hip operations. Only 3 of 14 patients with still existing joint-preserving operation were painless postoperatively and could continue their former job. The other patients suffered from pain and reductions of their activity of daily life. 4 of them had to retire early.

Abstract
The local and systemic release of thromboxane A2, prostaglandin I2, leukotriene B4 (LTB4), tumor necrosis factor alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), and interleukin-8 (IL-8) were studied before and after operation in 29 patients with acute and 22 with chronic posttraumatic osteomyelitis. Twenty patients without osteomyelitis, who underwent operations for fractures of the lower extremities, served as controls. Blood and tissue samples from the osteomyelitic and control groups were collected under defined conditions and mediators were determined by radioimmunoassay (thromboxane B2, 6-keto-prostaglandin F1 alpha, LTB4) or by enzyme-linked immunosorbent assay (TNF-alpha, IL-1 beta, and IL-8). In addition, common parameters (leukocyte count, C-reactive protein, temperature) were measured. The best correlation with acute disease activity was given by TNF-alpha, IL-6, IL-8, and LTB4. Plasma levels of these mediators in acute osteomyelitis were significantly increased compared to chronic osteomyelitis and to controls, respectively. Tissue samples from osteomyelitic focus showed significantly increased levels for IL-8, IL-6, TNF-alpha, IL-1 beta, and LTB4 in acute osteomyelitis, whereas the values for TxB2 and 6-keto-prostaglandin F1 alpha were only slightly increased compared to the chronic osteomyelitis group. This study describes the local and systemic liberation of various mediators in acute and chronic posttraumatic osteomyelitis in detail for the first time and provides data for pre- and postoperative monitoring of disease activity and demonstrates new pathogenetic and therapeutic aspects of bone modulation in osteomyelitis.

Abstract
With the aid of monoclonal antibodies, macrophages can be split into functionally distinct subpopulations on the basis of their phenotype. Absence of macrophage subtypes has been noted in chronic inflammatory processes, e.g. posttraumatic osteomyelitis, rheumatoid arthritis and sarcoidosis. In the inflammatory focus of acute septic arthritis (n = 13 patients) however, macrophages constitute the majority of immunocompetent cells. The inflammatory macrophage subtype 27E10 was clearly present in increased numbers in 11 of 13 biopsies from the inflammatory foci, showing the effector task of this subtype in synovial resistance. The anti-inflammatory macrophage subset RM3/1 was present in increased numbers in biopsies of infected tissue and the surrounding soft tissue. The occurrence of 25F9-positive macrophages, typical of the late phase of inflammation, varied widely in the biopsies.

Abstract
Macrophage subtypes were detected in cryostat sections of biopsies from patients with chronic osteomyelitis, acute joint infections and normal bone marrow, using monoclonal antibodies against different macrophage populations. The resident macrophage subtype 25F9, the gluco-corticoid-inducible macrophage RM 3/1 and the inflammatory type 27E10 were found in abundance in acute infections. They were also present in tissue sections of uninflamed bone marrow. By contrast, in about 50% of the biopsies from patients with chronic osteomyelitis a reduced number of macrophage subtypes, or even the lack of one or more macrophage subpopulations was found. The unusual absence of macrophage phenotypes seems to be restricted to the area of osteomyelitis because in the tissues of inflamed sinuses in these patients, the macrophage subtypes were present. These findings suggest a disturbance at the level of the macrophages which may contribute to the persistence of the inflammatory process in osteomyelitis.

Abstract
PMN (polymorphonuclear neutrophil) elastase is a proteolytic enzyme which is a biochemical marker for abnormal granulocyte stimulation. In inflammation and sepsis, excessive neutrophil stimulation results in significant amounts of PMN elastase being released into the plasma which indicates the severity of the disease and its prognosis. In 62 patients with osteomyelitis or suppurative arthritis, PMN elastase had a diagnostic sensitivity of 81%, which is comparable to the nonspecific erythrocyte sedimentation rate. Sensitivity of C-reactive protein (CRP) was 71%, fibrinogen 54% and leucocyte count 26%. PMN elastase was also useful in the follow up of patients with bone and joint infections; in the early post-operative period it became normal more quickly than the other findings unless the patients developed complications. Ten days after operation, PMN elastase was normal in 75% of the patients compared to the CRP which became normal in only 25%. Later both results were similar: on discharge from hospital, PMN elastase was normal in 77% and CRP in 71%.

Abstract
Osteocalcin is a vitamin K-dependent bone protein synthesized by osteoblasts. In generalized bone disorders serum osteocalcin correlates with osteoblast activity. Bone resorption and new bone formation occur in chronic osteomyelitis, dependent on the level of inflammatory activity. In 17 patients with active chronic osteomyelitis undergoing surgery, the serum levels of osteocalcin, alkaline phosphatase and C-reactive protein were measured before and after treatment. The osteocalcin levels were within the normal range preoperatively (10.8 +/- 11.0 micrograms/l), in the early postoperative period, and at discharge. It is therefore not a helpful marker in the clinical management of this condition.

Abstract
Macrophage subpopulations were detected immunohistochemically with the aid of monoclonal antibodies in tissue sections of 15 patients with posttraumatic osteomyelitis at the beginning of therapy and after combined operative/antibiotic treatment. Macrophages represent the majority of the immunocompetent cells in osteomyelitis tissue. Before the start of therapy, the acute inflammatory macrophage subtype 27E10 was absent or rarely found in 8/13 evaluable biopsies from the osteomyelitis focus, and a further decrease in the expression of these macrophage antigens was observed after treatment. The RM3/1-positive macrophage associated with the down-regulation of inflammation was detectable to a low extent in 4/13 evaluable biopsies from the osteomyelitis focus before the start of therapy. After treatment of the infection, an increase in this subtype was found in the cellular inflammatory infiltrates in the tissue samples examined. In 8/15 biopsies a marked expression of the RM3/1 antigen was observed. At the start of treatment, the macrophage 25F9, which dominates in the late phase of inflammation, was missing in 3/13 tissue samples. After combined operative/antibiotic treatment the 25F9-positive macrophage was found in all patients, having increased in 7/14 biopsies studied. These data suggest that treatment of posttraumatic osteomyelitis leads to a local macrophage subtype distribution in the osteomyelitis focus resembling the pattern of a late inflammatory reaction.

Abstract
In patients with chronic post-traumatic osteomyelitis, several deficits in immunological response were demonstrated. In a prospective trial of 20 patients with proven osteomyelitis, histological analysis of lymphocyte subsets in peripheral blood and in the infected bone tissue was performed. The effects of chronic osteomyelitis on lymphocyte subsets in the peripheral blood and in inflamed tissue were only slight. The T4/T8 ratio was diminished in only two patients and had no relationship to the clinical course. Interleukin 2 receptor determination was negative in 83% of biopsies of infected tissue. Osteomyelitis may possibly cause a defect in lymphocyte/macrophage cooperation.

Abstract
Similar to other chronic inflammatory diseases such as rheumatoid arthritis the distribution of macrophage subtypes seems to be disturbed in post-traumatic osteomyelitis. This atypical distribution is clearly locally restricted in osteomyelitis. 27E10-positive macrophages found only during the acute phase of inflammation were reduced in 39%, the 25F9-positive subtype, predominating in the late stage of inflammation, was missing in 33%. The antiinflammatory macrophage RM3/1 was decreased in 40% of the osteomyelitis biopsies. Local suppression of macrophage subsets has to be discussed as one of the reasons for the persistence of chronic inflammatory processes in osteomyelitis.

Abstract
A prospective trial was carried out in 156 unselected patients (41 men, mean age 67.5 years, 115 women, mean age 71.4 years) who had undergone total hip joint replacement because of degenerative or inflammatory arthritis or fracture of the neck of the femur. The excised femoral heads were subjected to three-stage bone bank screening so as to ascertain how many of them would pass the clinical, biochemical and microbiological exclusion criteria. Only 26 out of 156 femoral heads (17%) proved to be acceptable for the bone bank. Ninety patients (58%) were excluded on clinical grounds such as old age (over 80 years), malignant neoplasms, rheumatoid arthritis, previous intraarticular injections or long-term steroid medication. Positive hepatitis serology excluded 19%, and raised preoperative neopterin concentration excluded 25%, though three months postoperatively this was confirmed in only 2%. Routine neopterin assay seems to be a useful step towards improved bone bank screening, since neopterin concentration is clearly increased in recent virus infections such as HIV. Bacterial contamination was of no practical importance. Because of the low proportion of femoral heads passed as suitable for the bone bank, the existing exclusion criteria will have to be critically scrutinized, and alternative procedures for harvesting bone safe for transplantation (freeze drying, autoclaving, irradiation) will have to be employed.

Abstract
PMN elastase, a proteolytic enzyme, is a biochemical marker for pathologic granulocyte stimulation. In the presence of sepsis, excessive neutrophil stimulation occurs and significant amounts of PMN elastase are released into the plasma and serve as an indicator for the severity of the disease and the prognosis. PMN elastase is also a useful parameter for preoperative diagnostic management and postoperative follow-up of bone and joint infections. In patients with osteomyelitis and joint empyema (n = 48) PMN elastase had a sensitivity of 77%, which was only exceeded by that of the unspecific erythrocyte sedimentation rate (sensitivity 89%). Sensitivities of other inflammation parameters were lower: C-reactive protein (CRP) 67%, fibrinogen 50%, neopterin 32% and leukocyte count 21%. Determination of PMN elastase levels was also helpful in postoperative follow-up of patients with bone and joint infections. In the early postoperative period PMN elastase levels normalized more quickly than the other parameters unless patients actually developed complications. At the first postoperative determination (day 2-4 after surgery) 38% of the patients (n = 24) already had PMN elastase levels within the normal range (less than or equal to 40 micrograms/l) (CRP 13%). After 10 days PMN elastase was normal in 57% and CRP in 30% of the patients. Later on both parameters reacted similarly: by the time of discharge from hospital levels of PMN elastase were normal in 70% and CRP levels in 74%.

Abstract
Investigations in patients with chronic post-traumatic osteomyelitis could demonstrate several deficits in immunologic response: Phagocytic activity of phagocytes is lowered accompanied by a functional deminution of leukocyte receptors for C3. Intracellular killing is diminished. Investigations concerning T lymphocyte subpopulations verified a decrease in total T cells and helper/inducer T cells. Dysfunctions in specific humoral immune response are still debatable.

Abstract
In several investigations rejections were accused of being a possible cause for the loosening of hip endoprostheses. Using immunocytochemical techniques we studied the number and type of lymphocytes in the tissue adjacent to loosened hip endoprostheses. Tissue samples were taken from 18 patients being reoperated for a loosened endoprostheses. Impressive lymphocyte infiltrates were found in 4 of 18 patients (22%). These infiltrates only consisted of T-cells. In the other samples only few lymphocytes were detected belonging to T- and B-lymphocyte population, respectively. In our patients T-cell mediated rejections were of minor importance for the loosening of total hip replacement. B-cell accumulations were detected in none of the samples.

Abstract
Progressive liver fibrosis in rats develops when they are fed a diet deficient in choline. This diet also results in a pronounced and selective decrease in the liver microsomal content of a phase I drug-metabolizing enzyme belonging to the cytochrome P-450III gene family. Because P-450III cytochromes characteristically catalyze the N-demethylation of erythromycin, we believed that the production of breath CO2 from erythromycin would be dramatically reduced in choline-deficient rats. However, when 12 choline-deficient rats were compared with 9 control rats, the reduction in CO2 production from erythromycin (mean decrease 71%) was essentially identical to that from aminopyrine (mean decrease 69%), a substrate believed to be metabolized normally by the hepatocyte in fibrotic liver disease. Furthermore, we found that the relative erythromycin and aminopyrine demethylase activities were comparable when measured in vitro in liver microsomes prepared from the choline-deficient rats. To determine the molecular basis for the erythromycin demethylase activity in the choline-deficient rats, the liver microsomes were subjected to immunoblot analysis using a variety of polyclonal and monoclonal antibodies capable of distinguishing individual P-450III-related proteins. Our studies confirm that a major erythromycin demethylase belonging to the P-450III family, termed P-450p, was greatly reduced in the choline-deficient rat liver. However, the specific concentration of a second P-450p-related protein was essentially normal and that of a third P-450p-related protein was actually increased in the choline-deficient rat liver.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In two groups of patients the influence of unspecific immunostimulation (group 1) and combined immunosuppression (group 2) on lymphocyte subpopulations was studied. Patients constituting group 1 suffered from gastric and colorectal carcinoma, respectively, and were preoperatively treated with 10 mg whole cell preparation of immunostimulating Propionibacterium avidum KP-40 (Köln-Propioni, strain 40). Patients of group 2 were submitted to combined immunosuppressive therapy and treated with antilymphocyte globulin, prednisone, and azathioprine subsequent to renal transplantation. Immunostimulation with P. avidum KP-40 resulted in a significant increase (p less than or equal to 0.01) of the natural killer (NK) cell population, whereas total leukocyte and lymphocyte counts as well as helper and suppressor T lymphocyte subsets did not evidently differ from control values. On the contrary after immunosuppression all subsets of lymphocytes as well as NK cells significantly decreased.

Abstract
HIV-1 and HIV-2 antibodies, erythrocyte sedimentation rate, leucocytes and additionally serum neopterin levels were measured in 100 potential spongiosa donors. HIV antibodies were negative in all patients, whereas in 24% neopterin levels were elevated (greater than 10 nmol/l). Enhanced neopterin production is related to activity in cell-mediated immune response. In further investigations of these patients we found in 29% infections, 38% tumor diseases and 13% autoimmune diseases, all being exclusion criteria for spongiosa transplantation. In 3 patients increased neopterin values were the only pathological screening parameters. The measurement of serum neopterin levels showed to be a helpful parameter for the selection of spongiosa donors.

Abstract
In 15 patients the influence of unspecific immunostimulation/immunomodulation was studied. Patients constituting the therapeutical group suffered from colorectal- and gastric carcinoma, respectively, and were preoperatively treated with 10 mg whole cell preparation of immunomodulating Propionibacterium avidum KP-40. This adjuvant immunotherapy resulted in a significant increase (p less than 0.01) of the natural killer (NK)-cell population, however, total leukocyte and lymphocyte count as well as helper- and suppressor T-lymphocyte subsets did not significantly differ form control values.

Abstract
This prospective randomized study demonstrated that a preoperative intravenous infusion of 10 mg of the bacterial preparation Propionibacterium avidum KP-40 to patients with gastrointestinal tumors significantly (P less than 0.001) enhanced the secretion of neopterin, measurable as long-lasting (greater than 16 days) elevated urine excretion. Postoperative re-infusion of P. avidum KP-40 caused (statistically significant (p less than 0.001] re-enhancement of neopterin urine levels.
