Two cases of interferon-alpha-induced sarcoidosis koebnerized along venous drainage lines : new pathogenic insights and review of the literature of interferon-induced sarcoidosis

La sarcoïdose est une affection inflammatoire granuiomateuse systémique d'origine inconnue touchant le plus fréquemment les poumons, le système lymphoïde, le foie, les yeux et la peau. Dans cet article, nous rapportons deux cas de sarcoïdose cutanée touchant les avant-bras de deux patients anciens toxicomanes traités par interféron-a et ribavirine pour une hépatite C chronique. Nous procédons à une revue de la littérature de la sarcoïdose induite par l'interféron et élaborons une nouvelle hypothèse pathogénique de l'effet Koebner dans la sarcoïdose cutanée. Dans le cas des deux patients que nous décrivons, la distribution des lésions cutanées coïncide avec les anciens sites d'injection d'héroïne le long des trajets veineux des deux avant- bras. Cette distribution unique de l'atteinte cutanée suggère que les dommages tissulaires induits par la répétition d'injections percutanées puissent représenter un terrain favorisant au développement local d'une sarcoïdose cutanée. Fait intéressant, il a été récemment démontré que les cellules dendritiques plasmacytoïdes - sous-type de cellules dendritiques généralement absent de la peau - infiltrent rapidement les sites de peau lésée. Ces cellules sont la source d'une production endogène d'interféron-a, cytokine connue pour promouvoir le processus de cicatrisation, mais également pour favoriser le développement de sarcoïdose chez des individus prédisposés. Ainsi, nous postulons que les lésions de sarcoïdose cutanée limitées le long des trajets veineux - sites préalables d'injection percutanée de drogues - peuvent résulter d'une expression locale supplémentaire d'interféron-a. Celle-ci serait en outre favorisée par le traitement de ribavirine dans le cadre de l'hépatite C, connu pour renforcer la production endogène d'interféron-a. L'identification de nombreuses cellules dendritiques plasmacytoïdes circonscrivant l'inflammation granuiomateuse sur la biopsie cutanée de l'un de nos patients semble être un argument dans ce sens, conforté par l'absence de corps étranger détecté en microscopie par lumière polarisée. Cette observation semble pouvoir représenter un point crucial dans la compréhension des mécanismes physiopathologiques à la base de l'infiltration des cicatrices cutanées par la sarcoïdose. Des investigations supplémentaires doivent encore être effectuées afin de confirmer cette hypothèse.

Ammonium Phosphate/Fly Ash Road Base Construction, HR-294, Construction Report, 1987

The objective of this research project was to evaluate the construction and service performance of ammonium phosphate/fly ash (APFA) treated base courses of crushed fines and/or unprocessed sand. Specific test results related to construction of the test sections were included in the 1987 construction report by Iowa State University. The performance of the experimental sections is dealt with in this final report. This 1986 project demonstrated that in all cases the control sections utilizing a Type B base experienced dramatically less cracking in the surface than the APFA treated base sections. The cost per mix and subsequent surface maintenance costs for the APFA base sections, especially those having a substantial amount of limestone, were higher than the Type B base control sections. This type of construction may prove to be economical only when petroleum product costs escalate.

Abstract

Reliability of P-drive in occupational therapy following a short training session: A promising instrument measuring seniors' on-road driving competencies

Introduction Occupational therapists could play an important role in facilitating driving cessation for ageing drivers. This, however, requires an easy-to-learn, standardised on-road evaluation method. This study therefore investigates whether use of P-drive' could be reliably taught to occupational therapists via a short half-day training session. Method Using the English 26-item version of P-drive, two occupational therapists evaluated the driving ability of 24 home-dwelling drivers aged 70 years or over on a standardised on-road route. Experienced driving instructors' on-road, subjective evaluations were then compared with P-drive scores. Results Following a short half-day training session, P-drive was shown to have almost perfect between-rater reliability (ICC2,1=0.950, 95% CI 0.889 to 0.978). Reliability was stable across sessions including the training phase even if occupational therapists seemed to become slightly less severe in their ratings with experience. P-drive's score was related to the driving instructors' subjective evaluations of driving skills in a non-linear manner (R-2=0.445, p=0.021). Conclusion P-drive is a reliable instrument that can easily be taught to occupational therapists and implemented as a way of standardising the on-road driving test.

Survival after surgical drainage of malignant pericardial effusion.

OBJECTIVES: Management of malignant pericardial effusion (PE) is complex. Cardiac surgeons are not necessarily familiar with or are challenged by the many underlying etiologies. Analyzing risk factors for mortality may help to estimate the benefit of surgery in high-risk patients. METHODS: Patients undergoing a surgical pericardiotomy for malignant PE, between 2001 and 2011, were included. The influence of tumor type, disease extension, intra-pericardial tumor infiltration on early mortality and long-term survival as well as freedom from symptoms after drainage, and the use of sclerosing agents on PE recurrence rates was analyzed. RESULTS: PE drainage was performed on 46 patients 12 ± 30 months after tumor diagnosis. Malignant diseases were lung cancers (50 %), breast cancers (15 %), lymphoma and leukemia (13 %), cancers of the digestive tract (13 %), and others (9 %). 80 % of patients were symptomatic and symptom relief was achieved in 65 %. Nobody died during surgery. Recurrence rate was 4 %. Early in-hospital mortality was 22 %. After 1 year, 29 % of patients were alive. Eleven patients (24 %) had a complete tumor regression. Metastatic spread (p < 0.001), pericardial infiltration (p = 0.02), and intra-pericardial Bleomycin (p = 0.01) injection were associated with increased mortality. Hematological malignancies had a better prognosis for survival. CONCLUSION: Surgical pericardiotomy is safe, associated with a low recurrence rate and symptom relief in the majority of dyspneic patients. Intra-pericardial Bleomycin may reduce recurrent effusion but does not ameliorate survival. Long-term survival rate was low with an increased mortality in cases of metastatic spreading, pericardial infiltration, and as the tumor of origin: breast cancers. Leukemic and lymphatic tumors have better prognosis.

International STakeholder NETwork (ISTNET): creating a developmental neurotoxicity (DNT) testing road map for regulatory purposes.

A major problem in developmental neurotoxicity (DNT) risk assessment is the lack of toxicological hazard information for most compounds. Therefore, new approaches are being considered to provide adequate experimental data that allow regulatory decisions. This process requires a matching of regulatory needs on the one hand and the opportunities provided by new test systems and methods on the other hand. Alignment of academically and industrially driven assay development with regulatory needs in the field of DNT is a core mission of the International STakeholder NETwork (ISTNET) in DNT testing. The first meeting of ISTNET was held in Zurich on 23-24 January 2014 in order to explore the concept of adverse outcome pathway (AOP) to practical DNT testing. AOPs were considered promising tools to promote test systems development according to regulatory needs. Moreover, the AOP concept was identified as an important guiding principle to assemble predictive integrated testing strategies (ITSs) for DNT. The recommendations on a road map towards AOP-based DNT testing is considered a stepwise approach, operating initially with incomplete AOPs for compound grouping, and focussing on key events of neurodevelopment. Next steps to be considered in follow-up activities are the use of case studies to further apply the AOP concept in regulatory DNT testing, making use of AOP intersections (common key events) for economic development of screening assays, and addressing the transition from qualitative descriptions to quantitative network modelling.
