Regulatory assessment of in vitro skin corrosion and irritation data within the European framework: Workshop recommendations

Validated in vitro methods for skin corrosion and irritation were adopted by the OECD and by the European Union during the last decade. In the EU, Switzerland and countries adopting the EU legislation, these assays may allow the full replacement of animal testing for identifying and classifying compounds as skin corrosives, skin irritants, and non irritants. In order to develop harmonised recommendations on the use of in vitro data for regulatory assessment purposes within the European framework, a workshop was organized by the Swiss Federal Office of Public Health together with ECVAM and the BfR. It comprised stakeholders from various European countries involved in the process from in vitro testing to the regulatory assessment of in vitro data. Discussions addressed the following questions: (1) the information requirements considered useful for regulatory assessment; (2) the applicability of in vitro skin corrosion data to assign the corrosive subcategories as implemented by the EU Classification, Labelling and Packaging Regulation; (3) the applicability of testing strategies for determining skin corrosion and irritation hazards; and (4) the applicability of the adopted in vitro assays to test mixtures, preparations and dilutions. Overall, a number of agreements and recommendations were achieved in order to clarify and facilitate the assessment and use of in vitro data from regulatory accepted methods, and ultimately help regulators and scientists facing with the new in vitro approaches to evaluate skin irritation and corrosion hazards and risks without animal data.

Onychomycosis insensitive to systemic terbinafine and azole treatments reveals non-dermatophyte moulds as infectious agents.

BACKGROUND: Dermatophytes are the main cause of onychomycoses, but various non-dermatophyte filamentous fungi are often isolated from abnormal nails. OBJECTIVE: Our aim was the in situ identification of the fungal infectious agent in 8 cases of onychomycoses which could not be cured after systemic terbinafine and itraconazole treatment. METHODS: Fungal DNA was extracted from nail samples, and infectious fungi were identified by restriction fragment length polymorphism (RFLP) of amplified fungal ribosomal DNA using a previously described PCR/RFLP assay. RESULTS: PCR/RFLP identification of fungi in nails allows the identification of the infectious agent: Fusarium sp., Acremonium sp. and Aspergillus sp. were found as a sole infectious agent in 5, 2 and 1 cases, respectively. CONCLUSIONS: Fusarium spp. and other non-dermatophyte filamentous fungi are especially difficult to cure in onychomycoses utilising standard treatment with terbinafine and itraconazole. PCR fungal identification helps demonstrate the presence of moulds in order to prescribe alternative antifungal treatments.

Sensitive headspace gas chromatography analysis of free and conjugated 1-methoxy-2-propanol in urine

Glycol ethers still continue to be a workplace hazard due to their important use on an industrial scale. Currently, chronic occupational exposures to low levels of xenobiotics become increasingly relevant. Thus, sensitive analytical methods for detecting biomarkers of exposure are of interest in the field of occupational exposure assessment. 1-Methoxy-2-propanol (1M2P) is one of the dominant glycol ethers and the unmetabolized urinary fraction has been identified to be a good biological indicator of exposure. An existing analytical method including a solid-phase extraction and derivatization before GC/FID analysis is available but presents some disadvantages. We present here an alternative method for the determination of urinary 1M2P based on the headspace gas chromatography technique. We determined the 1M2P values by the direct headspace method for 47 samples that had previously been assayed by the solid-phase extraction and derivatization gas chromatography procedure. An inter-method comparison based on a Bland-Altman analysis showed that both techniques can be used interchangeably. The alternative method showed a tenfold lower limit of detection (0.1 mg/L) as well as good accuracy and precision which were determined by several urinary 1M2P analyses carried out on a series of urine samples obtained from a human volunteer study. The within- and between-run precisions were generally about 10%, which corresponds to the usual injection variability. We observed that the differences between the results obtained with both methods are not clinically relevant in comparison to the current biological exposure index of urinary 1M2P. Accordingly, the headspace gas chromatography technique turned out to be a more sensitive, accurate, and simple method for the determination of urinary 1M2P.[Authors]

Cardiomyocyte dysfunction during the chronic phase of Chagas disease

Chagas disease, which is caused by the parasite Trypanosoma cruzi, is an important cause of heart failure. We investigated modifications in the cellular electrophysiological and calcium-handling characteristics of an infected mouse heart during the chronic phase of the disease. The patch-clamp technique was used to record action potentials (APs) and L-type Ca2+ and transient outward K+ currents. [Ca2+]i changes were determined using confocal microscopy. Infected ventricular cells showed prolonged APs, reduced transient outward K+ and L-type Ca2+ currents and reduced Ca2+ release from the sarcoplasmic reticulum. Thus, the chronic phase of Chagas disease is characterised by cardiomyocyte dysfunction, which could lead to heart failure.

Il Discorso dell'amore verso la patria (1631) di Ludovico Zuccolo

Scopo di questo studio è la disamina e la divulgazione dei pregi letterari e del valore concettualmente innovativo del Discorso dell 'amore verso la patria di Ludovico Zuccolo. L'analisi dei contenuti dell'opera, unitamente alla puntualizzazione delle sue caratteristiche formali e stilistiche, permette di vedere come questo scrittore proponga, utilizzando la forma letteraria del discorso politico, una riuscita codificazione della tematica dei diritti e dei doveri dei cittadini verso la patria; operazione in cui si sostanzia, a mio avviso, l'apporto innovativo dello Zuccolo. Dopo l'iniziale riscoperta, da parte di Benedetto Croce, del capitolo delle Considerazioni sulla Ragion di Stato, l`opera dello Zuccolo ha generato un certo interesse critico fra gli studiosi di letteratura politica del "900" senza tuttavia divenire oggetto di contributi esaustivi malgrado, a nostro parere, la presenza di elementi di originalità di pensiero nel Discorso dell 'amore verso la patria. Inoltre, l'opinione degli specialisti non è mai stata unanime riguardo al valore e ai contenuti delle opere di questo autore. Se per il Croce, ne << La Critica >> del 1926, egli appare come colui che ha prodotto, «Lo scritto più acuto e originale sull'argomento [della Ragion di Stato], composto in quel seco1o.>> (p. 301), per altri egli si presenta come un dotto estensore di trattati politici nei quali sfoggia abilmente la sua erudizione classica e Luigi Firpo arriva a suggerire addirittura che lo Zuccolo sia colpevole di plagio proprio laddove tratta il tema della Ragion di Stato : Al punto in cui siamo, una cosa è certa, e cioè che i conti non tornano : non riesco a credere che uno scrittore inzeppi centinaia e centinaia di pagine di luoghi comuni, di erudizione d"accatto, di oziosità accademiche, e poi un bel mattino, morso dalla tarantola o baciato in fronte da Minerva, metta in carta il piccolo capolavoro, le pagine meditate e profonde, e perciò lungamente soffeite, che pure gli appartengono per una paternità incontestata e certa. Dico questo, perché in un caso del genere, non al miracolo s"avrebbe da credere, ma, semmai, al plagio. (1). Catherine Pitiot, nel suo saggio La retorica politica nell 'opera utopica di Ludovico Zuccolo, coglie invece in questo autore unicamente l"utopista che << lntende allontanarsi dalla realtà contemporanea per modificarla, correggerla e presentare un'in1magine che sia fondamentalmente diversa, a livello strutturale. >> (2). Di parere diametralmente opposto Rodolfo de Mattei, che attribuisce allo Zuccolo lo status di anti-utopista per eccellenza, tipico di uno scrittore che, Non ha voluto usufruire della facile libertà della fantasia per sovvertire l'ordine storico e per alterare arbitrariamente la natura umana, cioé per proporre un ordinamento mirante ad una radicale trasformazione della società e quindi di assai dubbia realizzazione. (3). Altri studiosi, fra cui Bruno Nediani, si sono dedicati alla descrizione della personalità dello Zuccolo, attingendo alle sue lettere - che lo stesso Nediani ha riscoperto - oltre che ai brevi accermi che di sé fa lo Zuccolo negli scritti. Dal saggio del Nediani, La personalità di Ludovico Zuccolo (1969), emerge la figura di un uomo tormentato e insoddisfatto, ossessionato dal sospetto dell"autorità ecclesiastica, costretto a procacciarsi impieghi inadeguati presso i potenti, all'inseguimento dell'obiettivo di una carriera che, comunque, finisce con il risultargli sempre, prima o poi, insopportabile. Più recentemente, Sergio Bertelli, nel suo contributo alla Storia della letteratura di Cecchi e Sapegno, ha aperto una nuova prospettiva sullo Zuccolo proponendolo come colui che, Spezza finalmente il cerchio moralistico costruito dal Botero attorno al pensiero machiavelliano e la ragion di stato cessa di essere giudicata vera o falsa, buona o malvagia, interessando in sé e per sé, cioé nei suoi presupposti e nei suoi fini esclusivamente politici.

Pre-diagnostic concordance with the WCRF/AICR guidelines and survival in European colorectal cancer patients: a cohort study.

BACKGROUND Cancer survivors are advised to follow lifestyle recommendations on diet, physical activity, and body fatness proposed by the World Cancer Research Fund/American Institute of Cancer Research (WCRF/AICR) for cancer prevention. Previous studies have demonstrated that higher concordance with these recommendations measured using an index score (the WCRF/AICR score) was associated with lower cancer incidence and mortality. The aim of this study was to evaluate the association between pre-diagnostic concordance with WCRF/AICR recommendations and mortality in colorectal cancer (CRC) patients. METHODS The association between the WCRF/AICR score (score range 0-6 in men and 0-7 in women; higher scores indicate greater concordance) assessed on average 6.4 years before diagnosis and CRC-specific (n = 872) and overall mortality (n = 1,113) was prospectively examined among 3,292 participants diagnosed with CRC in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort (mean follow-up time after diagnosis 4.2 years). Multivariable Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality. RESULTS The HRs (95% CIs) for CRC-specific mortality among participants in the second (score range in men/women: 2.25-2.75/3.25-3.75), third (3-3.75/4-4.75), and fourth (4-6/5-7) categories of the score were 0.87 (0.72-1.06), 0.74 (0.61-0.90), and 0.70 (0.56-0.89), respectively (P for trend <0.0001), compared to participants with the lowest concordance with the recommendations (category 1 of the score: 0-2/0-3). Similar HRs for overall mortality were observed (P for trend 0.004). Meeting the recommendations on body fatness and plant food consumption were associated with improved survival among CRC cases in mutually adjusted models. CONCLUSIONS Greater concordance with the WCRF/AICR recommendations on diet, physical activity, and body fatness prior to CRC diagnosis is associated with improved survival among CRC patients.

La mediació penal en l’àmbit del menor i la seva incidència a Catalunya

La mediació en l‘àmbit penal del menor és un mitjà innovador de resolució de conflictes, que s’ha de promoure per les seves innegables avantatges envers el model de punició tradicional. Permet que tots el agents afectats puguin intervenir i apropa la justícia a la societat, tot donant un paper fonamental a la víctima i afavorint-hi les possibilitats resocialitzadores i educatives del menor infractor. L’objectiu principal ha de ser facilitar al menor, que tot just comença la seva carrera criminal, les eines necessàries per evitar-ne l’evolució com a adult delinqüent, amb el consegüent benefici per a tota la societat. Igualment, la víctima, gran oblidada del procés penal, adquireix un nou protagonisme per decidir l‘abast de la seva reparació i, alhora, la societat reforça els mecanismes per obtenir la pau social. Aquestes finalitats tan loables mereixen l’esforç de les institucions per invertir en mitjans personals i materials que garanteixin l’eficàcia i la viabilitat dels programes de mediació i reparació. L’experiència a Catalunya, comunitat pionera en aquest àmbit, ve avalada per uns resultats excel·lents en el camp de la jurisdicció dels menors, segons reconeixen els mateixos protagonistes. Els resultats favorables de la mediació en l’àmbit del menor han permès, fins i tot, iniciar la primera experiència a l’Estat pel que fa a la mediació en la justícia penal d’adults. S’obren, doncs, noves possibilitats dins la filosofia del dret penal que ens permetran assolir en el futur solucions innovadores, proposades per les persones directament afectades. Aquest ha estat l’objectiu del nostre estudi, tot mirant d’aprofundir els avantatges de la mediació envers al sistema punitiu tradicional i els resultats de la seva implantació a Catalunya, així com cercar solucions que alleugeressin la sempre sobrecarregada Administració de justícia.
