Abstract
PURPOSE Due to limited imaging options, the visualization of a local relapse of prostate cancer used to pose a considerable challenge. However, since the integration of 18F-PSMA-1007-PET/CT into the clinic, a relapsed tumor can now easily be detected by hybrid imaging. The present study aimed to evaluate and map the allocate relapse in a large cohort of prostate cancer patients focusing on individual patient management conclusions for radiation therapy. PROCEDURES The current study included 135 men with prostate cancer after primary treatment who underwent 18F-PSMA-1007-PET/CT due to biochemical relapse detecting a local relapse. Imaging data were reassessed and analyzed with regard to relapse locations. For the correlation of tumor foci with clinical data, we used binary logistic regression models as well as the Kruskal-Wallis test and Mann-Whitney test. RESULTS In total, 69.6% of all patients (mean age: 65 years) underwent prostatectomy while 30.4% underwent radiation therapy. PET imaging detected most frequently a unifocal relapse (72.6%). There was a statistically significantly higher rate of ipsilateral cases among the relapsed tumors. Comparing both treatment approaches, tumors relapsed most commonly within the posterior region after surgery and transition/peripheral zone after radiation therapy, respectively. CONCLUSIONS The present study confirms that 18F-PSMA-1007-PET/CT is highly suitable for the localization and allocation of a local relapse in patients with prostate cancer. The data enable further optimizing dose prescriptions and target volume delineations of radiation therapy in the future.

Abstract
BackgroundSternocostoclavicular hyperostosis (SCCH) is an inflammatory bone disorder within the spectrum of chronic non-bacterial osteomyelitis. SCCH can be a manifestation of SAPHO syndrome, standing acronym for synovitis, acne, pustulosis, hyperostosis and osteitis, but also appears as an isolated clinical entity without joint and skin involvement1,2. Consensus on nomenclature, diagnostic classification, and therapy for SCCH is currently lacking3. Literature is diffuse, and spreads over a wide range of medical disciplines, calling for a first systematic overview.ObjectivesWe critically appraised literature with the aim to i) gain overview on the clinical presentation of SCCH and features leading to diagnosis and to ii) evaluate different treatment modalities and treatment response. We focused on the clinical entity of SCCH in adults, either isolated or as a part of SAPHO syndrome.MethodsWe conducted a systematic review and meta-analysis according to the PRISMA guidelines on the clinical presentation and therapeutic modalities applied in adult SCCH patients. Studies covering these respective domains were selected. Risk of bias was assessed using validated tools according to study type. Untransformed numerical data and double-arcsine transformed proportional data were analyzed in a random effects model in R-4.0.5; pooled proportions were reported with 95% confidence intervals (95%CI). Treatment response was categorized as good, partial, or none.Results28(i) and 12(ii) studies were included, containing heterogeneous data on 1818 patients. A female predisposition (67%, 95%CI 60-73) and major diagnostic delay (5 years 95%CI 3-7) were noted. Clinical presentation was marked by anterior chest pain (89%, 95%CI 79-96), and swelling (79%, 95%CI 62-91). Pustulosis palmoplantaris was present in 53%, 95%CI37-68, whereas acne (8%, 95%CI4-13) and peripheral arthritis (24%, 95%CI 11-39) were less prevalent. Inflammatory markers were inconsistently elevated and autoantibodies and HLA-B27 prevalence normal. Histopathology was unspecific, and cultures almost exclusively negative. Increased isotope uptake (99%, 95%CI96-100) was the most consistent imaging finding. Amongst manifold treatments (see Figure 1), NSAIDs were mainly partially effective. Pamidronate and biologicals (mainly TNF-α inhibitors) yielded good, though heterogeneous, response in 83%, 95%CI 60-98 and 56%, 95%CI 26-85 respectively.Figure 1.Treatment modalities applied in SCCH and their effects on bone pain (data from trials and several cohort studies combined)ConclusionLiterature on SCCH is extremely heterogeneous. Timely diagnosis proves challenging and mainly follows from the increased isotope uptake on nuclear examination. Biopsies, autoantibodies and HLA-status are non-contributory, and inflammatory biochemical profiles only variably detected. Pamidronate and TNF-α inhibitors emerged as promising therapies, but powered, placebo-controlled research with standardized measures of response is warranted. Inherently, international consensus on SCCH’s diagnostic classification and name appears critical to improve scientific collaboration on this rare disease, and to advance the development of clinical guidelines.References[1]Saghafi M, Henderson MJ and Buchanan WW.

Abstract
The goal was to study the effect of modulated sinusoidal currents electrophoresis and ultraphonophoresis of the phytocomplex on disruptions in the microcirculation system in the affected joint area and on changes in connective tissue metabolism parameters, metabolic processes, and electrolyte metabolism in patients with knee joint osteoarthritis. Seventy-two patients were randomly assigned to five groups. Patients of the first group were prescribed modulated sinusoidal currents electrophoresis of the phytocomplex. The second group was prescribed ultraphonophoresis of the phytocomplex, the third group was prescribed amplipulse therapy (modulated sinusoidal currents), the fourth group was prescribed ultrasound therapy, and the fifth group was prescribed basic drug therapy. Drug therapy of patients of the fifth group was comparable to the drug treatment of patients of the first four groups. The concentration of the phytocomplex in the working composition was 10%. Electrotherapy was carried out in the full-wave modulated sinusoidal currents mode with I and IV types of operation while ultrasound therapy was carried out in continuous mode with an ultrasound intensity of 0.6 W/cm2. To assess the state of microcirculation, the laser Doppler flowmetry method was used. The pronounced anti-dystrophic effect after the use of modulated sinusoidal currents electrophoresis and ultraphonophoresis of the phytocomplex in patients with knee joint osteoarthritis was based on the correction of microcirculatory disruptions: an increase in the capillary blood flow, an increase in the blood perfusion in tissues, and a decrease in congestion effects in the venular microcirculation. The use of modulated sinusoidal currents electrophoresis of the phytocomplex (ultraphonophoresis of the phytocomplex had an even greater effect) improved the connective tissue metabolism and the content of seromucoid, fibrinogen, and mucoproteins. The use of the studied treatment methods improved magnesium and phosphorus parameters of the electrolyte metabolism. Modulated sinusoidal currents electrophoresis and ultraphonophoresis of the phytocomplex contributed to the elimination of the metabolic imbalance of acid phosphatase. Ultraphonophoresis of the phytocomplex also contributed to balancing of the alanine aminotransferase and alkaline phosphatase content. As a result of the study, the effect of modulated sinusoidal currents electrophoresis and ultraphonophoresis of the phytocomplex on disruptions in the microcirculation system in the affected joint area and on changes in connective tissue metabolism parameters, metabolic processes, and electrolyte metabolism in patients with knee joint osteoarthritis was established. The obtained results provide the basis for further studies to assess the overall effectiveness of the use of modulated sinusoidal currents electrophoresis and ultraphonophoresis of the phytocomplex in patients with knee joint osteoarthritis.

Abstract
La loi de santé 2015 introduit le principe du tiers payant généralisé (TPG), qui a déjà généralisé l’opposition de la quasi-totalité des médecins libéraux. Au-delà des aspects symboliques du circuit de l’argent, objets de réflexions psychanalytiques plus ou moins légitimes, il s’agit aussi d’un processus macroéconomique qui permet aux assureurs privés d’avoir leur mot à dire sur ce qui est remboursé ou pas. Or les intérêts de la Sécurité sociale sont-ils tout à fait les mêmes que ceux des assureurs privés ? Les déclarations des dirigeants des groupes mutualistes sont tout à fait éclairantes sur le sujet… notamment leur regret de ne pas constituer eux-mêmes la plateforme de paiement qui reste aux mains de la Sécurité sociale. Tous les outils se mettent néanmoins progressivement en place pour passer du « remboursement selon les besoins, basé sur une cotisation selon les moyens », au principe assurantiel du « remboursement selon le niveau de cotisation et de risque ». Où est donc l’amélioration de l’accès, et pour quels soins ? Dans le même temps, les « mutuelles » deviennent obligatoires pour tous les salariés, ce qui accroît considérablement le nombre de cotisants, et « responsables » ce qui limite les remboursements notamment des dépassements d’honoraires. S’il s’agissait initialement de répondre au problème hautement médiatisé du renoncement aux soins, la loi de santé bénéficiera-t-elle bien aux patients ? Pendant ce temps, rien n’est fait sur les questions de démographie médicale, et de répartition géographique des praticiens libéraux, soumis aussi aux technocratiques nouvelles normes d’accessibilité aux personnes handicapées. L’unité créée chez les médecins libéraux contre cette loi permettra-t-elle de trouver des issues honorables ? Le pire pourrait être que les médecins libéraux se retrouvent mieux rémunérés grâce aux mutuelles, sur le modèle des rémunérations sur objectifs de santé publique (ROSP)…

Abstract
OBJECTIVE Osteomyelitis is an inflammation of the bone marrow mainly caused by bacteria such as Staphylococcus aureus. It typically affects long bones, e.g. femora, tibiae and humeri. Recently micro-computed tomography (μCT) techniques offer the opportunity to investigate bone micro-architecture in great detail. Since there is no information on long bone microstructure in osteomyelitis, we studied historic bone samples with osteomyelitis by μCT. MATERIALS AND METHODS We investigated 23 femora of 22 individuals suffering from osteomyelitis provided by the Collection of Anatomical Pathology, Museum of Natural History, Vienna (average age 44 ±19 years); 9 femora from body donors made available by the Department of Applied Anatomy, Medical University of Vienna (age range, 56-102 years) were studied as controls. Bone microstructure was assessed by μCT VISCOM X 8060 II with a minimal resolution of 18 μm. RESULTS In the osteomyelitic femora, most prominent alterations were seen in the cortical compartment. In 71.4% of the individuals with osteomyelitis, cortical porosity occurred. 57.1% of the individuals showed cortical thinning. In 42.9% trabecularisation of cortical bone was observed. CONCLUSION Osteomyelitis is associated with severe alterations of cortical bone structure otherwise typically observed at old age such as cortical porosity and cortical thinning.

Abstract
A spectroelectrochemical cell has been designed to combine electrochemistry and ultrafast two-dimensional infrared (2D-IR) spectroscopy, which is a powerful tool to extract structure and dynamics information on the femtosecond to picosecond time scale. Our design is based on a gold mirror with the dual role of performing electrochemistry and reflecting IR light. To provide the high optical surface quality required for laser spectroscopy, the gold surface is made by electron beam evaporation on a glass substrate. Electrochemical cycling facilitates in situ collection of ultrafast dynamics of redox-active molecules by means of 2D-IR. The IR beams are operated in reflection mode so that they travel twice through the sample, i.e., the signal size is doubled. This methodology is optimal for small sample volumes and successfully tested with the ferricyanide/ferrocyanide redox system of which the corresponding electrochemically induced 2D-IR difference spectrum is reported.

Abstract
A setup for the simultaneous measurement of mid-infrared spectra and static light scattering is described that can be used for the analysis of the formation of nanoscale and microscopic aggregates from smaller molecules to biopolymers. It can be easily integrated into sample chambers of infrared spectrometers or combined with laser beams from tunable infrared lasers. Here, its use for the analysis of the formation of amyloid fibrils from intact proteins is demonstrated. The formation of amyloid fibrils or plaques from proteins is a widespread and pathogenetic relevant process, and a number of diseases are caused and correlated with the deposition of amyloid fibrils in cells and tissues. The molecular mechanisms of these transformations, however, are still unclear. We report here the simultaneous measurement of infrared spectra and static light scattering for the analysis of fibril formation from egg-white lysozyme. The transformation of the native form into non-native forms rich in β-sheet structure is measured by analysis of the amide I spectral region in the infrared spectra, which is sensitive for local structures. At the same time, light scattering signals at forward direction as well as the forward/backward ratio, which are sensitive for the number of scattering centers and their approximate sizes, respectively, are collected for the analysis of fibril growth. Thermodynamic and kinetic parameters as well as mechanistic information are deduced from the combination of the two complementary techniques.

Abstract
Participants on spaceflights and international scientific analog Mars missions can encounter medical incidents (accidents, illnesses) and psychological issues (e.g., stress, group interaction, sleep disturbance, emotions). The aim of this study was to examine these parameters in a field crew living in a desert environment similar to Mars (Group 1) and in Mission Support Center (MSC) personnel on "Earth" (Group 2) during a 4-week mission. Of the 107 medical interventions in the field, 73 mainly minor incidents together with four near accidents and 29 medical checkup interventions were recorded. Of the 32 medical interventions, medical treatments for 23 incidents of minor severity were necessary in Group 2. Injuries (Group 1: 1.4/100 h, Group 2: 0.1/100 h) were significantly increased in the field, and illnesses (Group 1: 0.3/100 h, Group 2: 3.0/100 h) in the MSC personnel. Causes of accidents and illnesses are described. Psychological results show that emotions and stress remained stable in both groups. Sympathy, social competence, teamwork, and leadership showed high scores. These scores were lower on "Earth" but significantly increased in the last weeks. The Sahara's nighttime coldness was reflected in an increased wake-up frequency, and a longer sleeping time peaked in the third week, probably as a result of overfatigue. MARS2013 was a successful mission with highly motivated participants and minor medical incidents. For future analog missions and possibly long-distance open-space missions, some recommendations in terms of medical and psychological preparedness are made to reduce risks for field crew members and MSC personnel.

Abstract
"Push-Pull" is an inexpensive and eminently practical strategy designed for developing countries in order to exploit sound principles of chemical ecology for agricultural pest management. This strategy is specifically suitable for small holder farmers. Their experience can easily be integrated into existing farming practices in their immediate environment. "Push-pull" within one and a half decades became widely established and meanwhile is greatly beneficial to practitioners in East Africa, mainly Kenya. The classical push-pull approach used for applied plant-insect management was pioneered by Khan and Pickett (2000) and subsequent papers of Pickett (2003) and Khan et al. (2006, 2008). Relevant plant species explored so far were maize or sorghum intercropped with other East African plants (Desmodium spp. resp. Melinis minutiflora) possessing natural chemicals repellent resp. attractive for stem borer moths Chilo partellus (Lepidoptera), whereby Desmodium spp. was grown inside the maize rows while M. minutiflora surrounded it. Both simultaneous actions combined resulted in a significant decrease of stem borers in the area to be protected. A benefit to cost ratio of 2.5 was realized. Within a period of 15 years the number of subscribing farmers substantially increased from a few dozen to more than 80,000 in 2014. Two experiments along the paths of chemical ecology were undertaken between Sept 2012 and Feb 2013: One was designed to investigate if the legume D. intortum known to produce repellent volatiles against stem borer moths induces defence in Zea mays varieties. We looked at two open-pollinated farmers' varieties and two commercial hybrid varieties suspecting the farmers' varieties to be responsive rather than the hybrids. However, no defence induction was detected in this study so far. This could be explained by an insufficient production of defence inducing volatiles in leaves of D. intortum whereas flowers might produce a sufficient response. More detailed study is needed. A second approach made use of species-specific insect monitoring traps baited with highly specific female sex pheromones for attracting and monitoring destructive insect pests. The female sex pheromone (8-methyl-decane-2-ol propanoate) of Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae) (Western Corn Rootworm) is readily available as bait in the "Metcalf sticky cup trap" for trapping males, an extraordinarily sensitive technique for monitoring the presence or absence of male beetles in a given area. Li et al. (2006) had argued for the likelihood of easy immigration of this cosmopolitan maize pest into East Africa. Our results, however, so far indicate the absence of a local population in the area of Mbita, while not excluding its presence at Nairobi or Mombasa. Both investigations contribute to different aspects of Kenyan economic development and may be seen as two independent but complementary contributions towards livelihood improvement of small holder farmers in Kenya.

Abstract
BACKGROUND The scheduled update to the German S3 guidelines on fibromyalgia syndrome (FMS) by the Association of the Scientific Medical Societies ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften", AWMF; registration number 041/004) was planned starting in March 2011. MATERIALS AND METHODS The development of the guidelines was coordinated by the German Interdisciplinary Association for Pain Therapy ("Deutsche Interdisziplinären Vereinigung für Schmerztherapie", DIVS), 9 scientific medical societies and 2 patient self-help organizations. Eight working groups with a total of 50 members were evenly balanced in terms of gender, medical field, potential conflicts of interest and hierarchical position in the medical and scientific fields. Literature searches were performed using the Medline, PsycInfo, Scopus and Cochrane Library databases (until December 2010). The grading of the strength of the evidence followed the scheme of the Oxford Centre for Evidence-Based Medicine. The recommendations were based on level of evidence, efficacy (meta-analysis of the outcomes pain, sleep, fatigue and health-related quality of life), acceptability (total dropout rate), risks (adverse events) and applicability of treatment modalities in the German health care system. The formulation and grading of recommendations was accomplished using a multi-step, formal consensus process. The guidelines were reviewed by the boards of the participating scientific medical societies. RESULTS AND CONCLUSION Amitriptyline and-in case of comorbid depressive disorder or generalized anxiety disorder-duloxetine are recommended. Off-label use of duloxetine and pregabalin can be considered in case of no comorbid mental disorder. Strong opioids are not recommended.

Abstract
BACKGROUND MicroRNA-143 (miRNA-143) is frequently down-regulated in colorectal cancer (CRC) and may influence CRC cell proliferation, apoptosis and sensitivity to 5-fluorouracil. mRNA encoded by the KRAS oncogene has been identified as a target of miRNA-143. However, the prognostic significance of miRNA-143 expression and the ability to predict patient response to epidermal growth factor receptor (EGFR)-targeted agents have not yet been explored. METHODS We examined 77 CRC patients who were identified by pyrosequencing to have wild-type KRAS and were subsequently treated with EGFR-targeted therapy with the monoclonal antibodies cetuximab or panitumumab. MicroRNA-143 expression was measured in CRC tissue and corresponding non-neoplastic colon tissue by RT-PCR and its expression level was correlated with clinico-pathological characteristics. Univariate and multivariate analyses were used to calculate cancer-specific survival (CSS). The progression-free survival (PFS) and objective response rates on EGFR-targeted therapy were also evaluated. RESULTS Down-regulation of miRNA-143 was observed in 47 out of 77 (61%) tumours. Multivariate Cox regression analysis identified low levels of miRNA-143 expression as an independent prognostic factor with respect to CSS (hazard ratio=1.92, confidence interval=1.1-3.4, P=0.024). A significant difference was also observed with regard to PFS on EGFR-targeted therapy (P=0.031), but there were no significant differences with regard to the objective response rates. CONCLUSION Our data indicate that miRNA-143 expression levels serve as an independent prognostic biomarker for CRC in KRAS wild-type patients. No role for miRNA-143 expression as a predictive biomarker for EGFR-targeted agents could be identified. Given its negative impact on CSS and PFS, miRNA-143 represents a novel prognosticator and a promising drug target for patients with CRC.

Abstract
BACKGROUND An interdisciplinary guideline for the treatment of fibromyalgia syndrome (FMS) and chronic widespread pain (CWP) was developed in cooperation with ten German medical and psychological associations and two patients' self-help organizations. METHODS Using the Cochrane Collaboration Reviews (1993-12/2006), Medline (1980-2006), PsychInfo (1966-12/2006), and Scopus (1980-12/ 2006) a systematic literature search was performed, which included all randomised controlled trials (RCT) evaluating multicomponent therapy in FMS and CWP. Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine. The strength of recommendation was graded according to the German program for disease management guidelines. Consensus was achieved using a multi-step nominal group procedure. RESULTS The short-term use of amitriptyline is strongly recommended (grade A) and the short-term use of fluoxetine und duloxetine is recommended (grade B). CONCLUSIONS The recommendations regarding pharmacological treatment of FMS are limited by the short duration of the RCT, the lack of follow-ups and absence of cost-effectiveness studies.

Abstract
In dorsal root ganglia substance P is synthesized ribosomally, probably via a precursor. A second peptide, apparently a modified form of substance P (8-11), is cosynthesized with substance P and transported with it down both dorsal roots and peripheral branches. Four times as much substance P-like immunoreactivity is transported peripherally as centrally. Only 30% of axonal substance P-like immunoreactivity is available for rapid axonal transport and this is transported at a rate of 4.9 mm h-1. Axonal transport is not necessary for substance P synthesis. Doses of anisomycin which inhibit CNS protein synthesis by more than 95% do not cause any fall in substance P levels over an eight-hour period in ganglia, spinal cord or brain, suggesting that turnover is slower than that of conventional transmitters. However, stimulation of the hindlimbs of these animals reduces substance P levels in the dorsal horn. The turnover rate of spinal cord substance P, estimated either by relating the amount transported down dorsal roots to that in terminals or by measuring the decline of substance P levels after intrathecal colchicine, is four to five days. The functional organization of the substance P neuron is discussed with particular reference to the maintenance of peptide levels in terminals.

Abstract
The roles of insulin-like growth factors (IGFs) in regulating growth and their modulation by six IGF binding proteins (IGFBP) are well established. IGFBP-5, the most abundant IGFBP stored in bone, is an important regulator of bone formation via IGF-dependent and -independent mechanisms. Two new proteins, four and a half lim (FHL)-2, a transcription modulator that interacts with IGFBP-5, and a disintegrin and metalloprotease (ADAM)-9, an IGFBP-5 protease, have been identified as potential regulators of IGFBP-5 action in bone. We tested the hypothesis that agents which modulate bone formation by regulating IGFBP-5 expression would also regulate FHL-2 and ADAM-9 expression in a coordinated manner. We evaluated the expression of IGFBP-5, FHL-2, and ADAM-9 by real-time reverse transcriptase (RT)-PCR during differentiation of mouse bone marrow stromal cells into osteoblasts and in response to treatment with bone formation modulators in the LSaOS human osteosarcoma cell line. IGFBP-5 and FHL-2 increased 4.3- and 3.0-fold (P < or = 0.01), respectively, during osteoblast differentiation. Dexamethasone (Dex), an inhibitor of bone formation, decreased IGFBP-5 and FHL-2 and increased ADAM-9 in LSaOS cells (P < or = 0.05). Bone morphogenic protein (BMP)-7, a stimulator of bone formation, increased IGFBP-5 and decreased ADAM-9 (P<0.01). To determine if BMP-7 would eliminate Dex inhibition of IGFBP-5, cells were treated with Dex+BMP-7. The BMP-7-induced increase in IGFBP-5 was reduced, but not eliminated, in the presence of Dex (P < or = 0.01), indicating that BMP-7 and Dex may regulate IGFBP-5 via different mechanisms. Transforming growth factor (TGF)-beta, a stimulator of bone formation, increased IGFBP-5 and FHL-2 expression (P < or = 0.01). IGF-I and TNF-alpha decreased expression of ADAM-9 (P<0.05). In conclusion, our findings are consistent with the hypothesis that FHL-2 and ADAM-9 are important modulators of IGFBP-5 actions and are, in part, regulated in a coordinated manner in bone.

Abstract
Germ cell tumour is the most frequent malignant tumour type in young men with a 100% rise in the incidence every 20 years. Despite this, the high sensitivity of germ cell tumours to platinum-based chemotherapy, together with radiation and surgical measures, leads to the high cure rate of > or = 99% in early stages and 90%, 75-80% and 50% in advanced disease with 'good', 'intermediate' and 'poor' prognostic criteria (IGCCCG classification), respectively. The high cure rate in patients with limited metastatic disease allows the reduction of overall treatment load, and therefore less acute and long-term toxicity, e.g. organ sparing surgery for specific cases, reduced dose and treatment volume of irradiation or substitution of node dissection by surveillance or adjuvant chemotherapy according to the presence or absence of vascular invasion. Thus, different treatment options according to prognostic factors including histology, stage and patient factors and possibilities of the treating centre as well may be used to define the treatment strategy which is definitively chosen for an individual patient. However, this strategy of reduction of treatment load as well as the treatment itself require very high expertise of the treating physician with careful management and follow-up and thorough cooperation by the patient as well to maintain the high rate for cure. Treatment decisions must be based on the available evidence which has been the basis for this consensus guideline delivering a clear proposal for diagnostic and treatment measures in each stage of gonadal and extragonadal germ cell tumour and individual clinical situations. Since this guideline is based on the highest evidence level available today, a deviation from these proposals should be a rare and justified exception.

Abstract
BACKGROUND Empirical data on the impact of personality pathology on acute treatment outcome for depression are mixed, in part because of challenges posed by assessing trait-like personality patterns while patients are in an active mood episode. To our knowledge, no previous study has examined the effect of personality pathology on maintenance treatment outcome. By maintenance treatment we refer to long-term treatment provided to prevent depression recurrence among remitted patients. METHOD Structured Clinical Interviews for the DSM-III-R Personality Disorders (SCID-II) were obtained on a sample of 125 recurrently depressed women following sustained remission of the acute mood episode and prior to entering maintenance treatment. SCID-II interviews were then repeated following 1 and 2 years of maintenance interpersonal psychotherapy. RESULTS At the pre-maintenance assessment, 21.6% of the sample met SCID-II personality disorder criteria. Co-morbid personality pathology was related to an earlier age of onset, more previous depressive episodes, and a greater need for adjunctive pharmacotherapy to achieve remission of the acute mood episode. Co-morbid personality pathology predicted both higher rates of depression recurrence and a shorter time to recurrence over the 2-year course of maintenance treatment. Notably, among those patients who remained depression-free, continuous levels of personality pathology steadily declined over the 2-year course of maintenance therapy. CONCLUSIONS Results highlight the need for early and effective intervention of both episodic mood disorder and inter-episode interpersonal dysfunction inherent to the personality disorders. Future maintenance treatment trials are needed to clarify the relationship between episodic mood disorder and personality function over time.

Abstract
Patients experiencing constant pain continue to receive less than optimal treatment. In the case of cancer pain in particular, adequate therapy is a must. On the basis of the WHO analgesic ladder, nonopioids and opioids of varying potency must be applied as required, together with antiemetics, laxatives, gastric-protective preparations and bisphosphonates to ameliorate side effects. A particular problem in the treatment of cancer pain is the suddenly occurring stress and perforation pain. This can be reduced with fast-acting opioids such as the fentanyl stick. If the patient does not respond adequately to any of the noninvasive methods, local anesthetics and opiates applied via an i.v. pump system that permits bolus application and spinal and epidural methods have proven useful.

Abstract
Of 405 patients with stage IV transitional cell carcinoma from an international multicenter phase III trial, 70 were randomized in Germany to receive either gemcitabine/cisplatin or standard MVAC systemic chemotherapy for locally advanced or metastatic urothelial cancer. Overall survival as the primary endpoint of the study was similar in both arms (median survival GC 15.4 months vs MVAC 16.1 months), as were tumor-specific survival and time to progressive disease. In the intent-to-treat analysis, the 5-year overall survival rate was 10% for patients randomized to GC and 18% randomized to MVAC. Tumor overall response rates (GC 54%, MVAC 53%) were similar. The toxic death rate was 0% in the GC arm and 3% (one patient) in the MVAC arm. Significantly more GC than MVAC patients experienced grade 3/4 anemia (GC 52%, MVAC 20%) with significantly more red blood cell transfusions in the GC arm.Significantly more GC than MVAC patients had grade 3/4 thrombocytopenia (GC 54%, MVAC 17%) without grade 3/4 hemorrhage or hematuria in either arm. More MVAC patients experienced grade 3/4 neutropenia (GC 56%, MVAC 61%, p=1.000), neutropenic or leukopenic fever (GC 0%, MVAC 10%, p=0.237), mucositis (GC 0%, MVAC 7%, p=0.495), and alopecia (GC 6%, MVAC 36%, p=0.004). GC represents a reasonable alternative for the palliative treatment of patients with locally advanced and metastatic transitional cell carcinoma. Sustained long-term survival was only found for patients with locally advanced cancer, lymphatic metastases, or solitary distant metastasis but not for visceral metastatic disease.
