    Notes: Abstract Background:Gemcitabine is active in patients with otherwiseresistant or refractory ovarian cancer. As the drug is well tolerated, studiesusing gemcitabine combined with other antineoplastic agents are needed. Theaim of the study was to determine the maximum tolerated dose (MTD) ofepirubicin combined with gemcitabine, with and without support of G-CSF. Patients and methods:Patients with platinum-resistant orrefractory ovarian cancer were eligible. Gemcitabine (G) (starting dose 800mg/m2 day 1 and 8; 200 mg/m2 escalation per level) andepirubicin (E) (starting dose 60 mg/m2 day 1; 15 mg/m2escalation per level) were given every 21 days for four to six cycles. G-CSF(filgrastim 5 µg/kg/die) was given in case of grade 4 neutropenia(levels without support) or from day 9 up to leukocyte count〉10,000/mm3 after nadir (levels with support). Cohorts of threepatients were enrolled at each level, and another three patients were planned,if one dose-limiting toxicity (DLT) was registered. MTD was determined firstwithout and then with G-CSF. Results:Four levels were studied (G 800 + E 60; G 1000 + E 60;G 1000 + E 75; G 1000 + E 75 + G-CSF) with four, four, three and threepatients enrolled, respectively. DLT (grade 4 febrile neutropenia) wasobserved in two patients at level 3. Thus, G1000 + E 60 mg/m2 wasthe MTD without G-CSF. The addition of prophylactic G-CSF did not allow afurther increase of the dose and grade 4 thrombocytopenia was the DLT at level4. Non-hematological toxicity was mild. Grade 2 mucositis was reported in fourpatients. Among the 13 patients with measurable or evaluable disease, 3partial responses were observed for an overall response rate of 23.1%. Conclusions:The combination of gemcitabine 1000 mg/m2(day 1, 8) and epirubicin at 60 mg/m2 (day 1) is a feasibletherapy. Grade 4 neutropenia is frequent and G-CSF support is often required.With prophylactic support of G-CSF, the DLT is thrombocytopenia.

    Description / Table of Contents: Sommario Scopo di questo studio è stato indagare l'eventuale influenza della fistola arterovenosa (FAV) sulla velocità di conduzione nervosa in pazienti in trattamento emodialitico periodico, per le sue pssibili implicazioni nella patogenesi della sindrome del tunnel carpale (CTS). Vengono presentati i dati relativi a 22 pazienti. I risultati non hanno evidenziato differenze statisticamente significative dei parametri elettrografici considerati. Pertanto i nostri dati suggeriscono che la FAV (eseguita secondo la tecnica “termino-terminale”) non riveste un ruolo significativo nell'alterazione della conduzione nervosa. È possibile che fenomeni di furto nel territorio dell'arteria radiale, che si verificano con FAV eseguite con altra modalità, siano, almeno in parte, responsabili dei casi di CTS segnalati nella letteratura al riguardo.
    Notes: Abstract The aim of this study was to investigate the possible influence of arteriovenous fistula (AVF) on nerve conduction velocity in patients on intermittent hemodialysis and its relevance to the pathogenesis of carpal tunnel syndrome (CTS). The data on 22 patients showed no statistically significant differences in the electrographic parameters considered. This suggests that AVF by the end-to-end method plays no significant part in the alteration of nerve conduction. Possibly radial steal phenomena, which occur with other types of AVF, are at least partly responsible for the reported cases of CTS.

    Notes: The performance of the gas chromatography/alternating current plasma detector as a selective detector for organolead compounds is investigated. The helium make-up flow rate and the spatial position from which the lead emission is viewed, have an effect on the detector response. The detection limit for tetrabutyl lead was established as 130 pg/s and the lead selectivity ratio was found to exceed 13,800. Some applications of organolead determination in complex matrices were also studied in order to demonstrate the selectivity and sensitivity of the alternating current plasma detector.
