Abstract
BACKGROUND AND AIMS Highly sensitive technologies are available for the molecular characterization of solid tumors, including digital PCR (dPCR). Liquid biopsy, based on the analysis of cell-free DNA (cfDNA), is often used to assess EGFR or RAS alterations in lung and colorectal cancers. Our study aimed to compare the results of two different dPCR platforms for the detection of mutations in cfDNA. METHODS Plasma samples from lung and colorectal cancer patients collected as per routine procedures have been tested. cfDNA Was extracted from plasma, and samples were screened on the droplet digital PCR (ddPCR, BioRad) and solid dPCR QIAcuity (Qiagen). RESULTS A total of 42 samples were analyzed, obtained from 20 Non-Small Cell Lung Cancer (NSCLC) patients carrying an EGFR or a KRAS mutation on tissue at diagnosis, and from 22 samples of colorectal cancer (CRC) patients, 10 of which presenting a KRAS mutation. EGFR mutation detection was 58.8% for ddPCR and 100% for dPCR (κ = 0.54; 95% CI, 0.37-0.71), compared to tissue results. The detection rate for RAS mutations was 72.7% for ddPCR and 86.4% for dPCR (κ = 0.34; 95% CI, 0.01-0.68), compared to tissue results. CONCLUSIONS This study showed moderate agreement between dPCR and ddPCR. Sampling effect or threshold settings may potentially explain the differences in the cfDNA data between the two different platforms.

Abstract
BACKGROUND The health risk level in the operating theaters is directly correlated to the safety level offered by the healthcare facilities. This is the reason why the national Authorities released several regulations in order to monitor better environmental conditions of the operating theaters, to prevent occupational injuries and disease and to optimize working conditions. For the monitoring of environmental quality of the operating theaters following parameters are considered: quantity of supplied gases, anesthetics concentration, operating theatres volume measurement, air change rate, air conditioning system and air filtration. The objective is to minimize the risks in the operating theaters and to provide the optimal environmental working conditions. This paper reports the environmental conditions of operating rooms performed for several years in the public hospitals of the Campania Region. METHODS Investigation of environmental conditions of 162 operating theaters in Campania Region from January 2012 till July 2014 was conducted. Monitoring and analysis of physical and chemical parameters was done. The analysis of the results has been made considering specific standards suggested by national and international regulations. RESULTS The study showed that 75% of the operating theaters presented normal values for microclimatic monitoring, while the 25% of the operating theaters had at least one parameter outside the limits. The monitoring of the anesthetics gases showed that in 9% of measurements of nitrous oxides and 4% of measurements of halogenated was not within the normal values.

Abstract
Aircraft are constructed by modules that are covered by a "primer" layer, which can often contain hexavalent chromium [Cr(VI)], known carcinogen to humans. While the occupational exposure to Cr(VI) during aircraft painting is ascertained, the exposure assessment of assembly workers (assemblers) requires investigations. Three biological monitoring campaigns (BM-I,II,III) were performed in an aviation industry, on homogeneous groups of assemblers (N = 43) and controls (N = 23), by measuring chromium concentrations in end-shift urine collected at the end of the working week and the chromium concentration difference between end- and before-shift urines. BM-I was conducted on full-time workers, BM-II was performed on workers after a 3-4 day absence from work, BM-III on workers using ecoprimers with lower Cr(VI) content. Samples were analyzed by atomic absorption spectroscopy and mean values were compared by T-test. Even if Cr concentrations measured during BM-I were lower than Biological Exposure Indices by ACGIH, statistically significant differences were found between urinary Cr concentrations of workers and controls. Despite 3-4 days of absence from work, urinary chromium concentrations measured during BM-II were still higher than references from nonoccupationally exposed populations. In the BM-III campaign, the obtained preliminary results suggested the efficacy of using ecoprimers. The healthcare of workers exposed to carcinogenic agents follows the principle of limiting the exposure to "the minimum technically possible". The obtained results evidence that assemblers of aviation industries, whose task does not involve the direct use of primers containing Cr(VI), show an albeit slight occupational exposure to Cr(VI), that must be carefully taken into consideration in planning suitable prevention measures during risk assessment and management processes.

Abstract
BACKGROUND Power plant workers are potentially exposed to nitrogen dioxide (NO2) and may therefore be at higher risk of pulmonary diseases than the general population. AIMS To assess the association of NO2 exposure with spirometric abnormalities in power plant workers. METHODS Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and forced expiratory ratio (FER = FEV1/FVC) were correlated with demographic characteristics, smoking history and environmental exposure to NO2 in power plant workers exposed to environmental NO2 at work and in a control group of administrative employees. Twenty-four hour environmental NO2 concentrations were measured at each workplace. RESULTS The concentrations of environmental NO2 ranged from 1.21 to 7.82 mg m(-3) with a mean value of 3.91 + 1.51 mg m(-3). The results showed that FEV1 and FVC were significantly lower in 347 power plant workers than in the 349 controls (P < 0.001). The FER was significantly correlated with age, environmental NO2 concentration, smoking and height. CONCLUSIONS Occupational exposure to NO2 emissions in power plants is significantly associated with lung function abnormalities as assessed by spirometry. Spirometric measurements in power plant workers exposed to NO2 emissions may be an effective means of detecting early signs of impaired respiratory health in this group of workers.

Abstract
Nociceptin/orphanin FQ (N/OFQ) acts as an anxiolytic-like agent in the rat and behaves as a functional antagonist of corticotropin-releasing factor (CRF) due to its ability to oppose CRF biological actions. In response to stress, CRF triggers changes in neurotransmitter systems including serotonin (5-HT). The role of 5-HT1A receptor in anxiety has been supported by preclinical and clinical studies. The present study investigated the possible functional antagonism between N/OFQ (1nmol/rat) and CRF (0.2nmol/rat) in anxiety-related conditions in rats, using elevated plus maze and defensive burying tests, in order to confirm previous literature results. Moreover, possible changes in the serotonergic system were studied in areas rich of serotonergic neurons: frontal cortex and pons. In both tests N/OFQ showed anxiolytic-like effects while CRF displayed anxiogenic-like effects. N/OFQ before CRF treatment counteracted the anxiogenic-like effects evoked by CRF. In frontal cortex, N/OFQ significantly decreased 5-HT levels but did not modify the hydroxyindoleacetic acid (5-HIAA) ones; CRF modified neither 5-HT nor 5-HIAA content but counteracted changes induced by N/OFQ alone. In pons, N/OFQ induced no change in serotonergic activity while CRF significantly decreased 5-HT levels and increased 5-HIAA content. The two peptides' combination reinstated serotonergic parameters to controls. In frontal cortex, N/OFQ increased the 5HT1A receptor density but reduced its affinity, while CRF alone did not induce any change. In pons, CRF decreased 5HT1ABmax and KD whereas N/OFQ was ineffective. All biochemical modifications were reverted by N/OFQ plus CRF treatment. The present study confirms that N/OFQ counteracts CRF anxiogenic-like effects in the behavioral tests evaluated. These effects may involve central serotonergic mechanisms since N/OFQ plus CRF induces a reversion of serotonergic changes provoked by single peptide. Our data support the hypothesis that N/OFQ may behave as functional CRF antagonist, this action being of interest for the treatment of anxiety disorders.

Abstract
Neuropeptide S (NPS) produces several biological actions by activating a formerly orphan GPCR, now named NPS receptor (NPSR). It has been previously demonstrated that NPS stimulates murine leukocyte chemotaxis in vitro. In the present study we investigated the ability of NPS, in comparison with the proinflammatory peptide formyl-Met-Leu-Phe (fMLP), to stimulate human monocyte chemotaxis. At a concentration of 10(-8)M fMLP significantly stimulated chemotaxis. NPS produced a concentration dependent chemotactic action over the concentration range 10(-12) to 10(-5)M. The NPSR antagonists [D-Cys((t)Bu)(5)]NPS, [(t)Bu-D-Gly(5)]NPS and SHA 68 were used to pharmacologically characterize NPS action. Monocyte chemoattractant effect of NPS, but not fMLP, was completely blocked by either peptide antagonists or SHA with the nonpeptide molecule being more potent. None of the NPSR antagonists modified per se random cell migration. Thus, the present study demonstrated that NPS is able to stimulate human monocyte chemotaxis and that this effect is entirely due to selective NPSR activation.

Abstract
Neuropeptide S (NPS) regulates various biological functions by selectively activating the NPS receptor (NPSR). Recently, the NPSR ligand [(t)Bu-D-Gly(5)]NPS was generated and in vitro characterized as a pure antagonist at the mouse NPSR. In the present study the pharmacological profile of [(t)Bu-D-Gly(5)]NPS has been investigated. [(t)Bu-D-Gly(5)]NPS activity was evaluated in vitro in the calcium mobilization assay at the rat NPSR and in vivo in the locomotor activity and righting reflex tests in mice and in the elevated plus maze and defensive burying assays in rats. In vitro, [(t)Bu-D-Gly(5)]NPS was inactive per se while it inhibited the calcium mobilization induced by 30 nM NPS (pK(B) 7.42). In Schild analysis experiments [(t)Bu-D-Gly(5)]NPS (0.1-10 μM) produced a concentration-dependent rightward shift of the concentration-response curve to NPS, showing a pA(2) value of 7.17. In mouse locomotor activity experiments, supraspinal injection of [(t)Bu-D-Gly(5)]NPS (1-10 nmol) dose dependently counteracted NPS (0.1 nmol) stimulant effects. In the mouse righting reflex assay [(t)Bu-D-Gly(5)]NPS (0.1-10 nmol) fully prevented the arousal-promoting action of the natural peptide (0.1 nmol). Finally, [(t)Bu-D-Gly(5)]NPS (3-30 nmol) was able to completely block NPS (1 nmol) anxiolytic-like actions in rat elevated plus maze and defensive burying assays. Collectively, the present results demonstrated that [(t)Bu-D-Gly(5)]NPS behaves both in vitro and in vivo as a pure and potent NPSR antagonist. This compound represents a novel and useful tool for investigating the pharmacology and neurobiology of the NPS/NPSR system.

Abstract
BACKGROUND A reliable early marker is required for diagnosis of cobalamin deficiency. We calculated an appropriate holotranscobalamin (HoloTC) cut-off point for identifying cobalamin deficiency using an immunoenzymatic assay. METHODS Determination of the cut-off threshold and correlation between HoloTC and the other diagnostic parameters routinely used for vitamin B(12) deficiency [total vitamin B(12) (tB(12)), folate, homocysteine] were measured in 250 routine blood specimens from 107 men (mean age 59.0+/-18.8 years) and 143 women (mean age 54.2+/-23.1 years). The inclusion criterion was serum tB(12) concentration <or=221 pmol/L. RESULTS Analytical performance results agreed with those reported by others. A weak correlation (R=0.42) was found between HoloTC and tB(12). A 40 pmol/L cut-off threshold was chosen for HoloTC and the associated sensitivity and specificity was 0.86 and 0.66, respectively. Out of 250 tested samples, 126 showed tB(12) concentrations 139-221 pmol/L (gray zone, GZ) and 124 had tB(12) concentrations <139 pmol/L (low, L). Values less than the cut-off for HoloTC were present in 68.2% and 37.9% of cases in the GZ and L group, respectively (p<0.01), and in 53.2% of subjects. CONCLUSIONS Our results confirmed the analytical reliability of the AxSYM HoloTC assay. The method is adequate for routine use and a cut-off threshold of 40 pmol/L is appropriate for assessing cobalamin deficiency in populations with reduced tB(12) values.

Abstract
The nucleotide sequence of the variable 16S-23S rDNA internal transcribed spacer (ITS) was determined in 32 strains of Mycobacterium avium, including 29 clinical isolates, two environmental isolates and the reference strain M. avium ATCC 35712. The results were compared with those obtained by the IS1245-based restriction fragment length polymorphism (RFLP) assay. The strains belonged to three distinct ITS sequevars, Mav-A, Mav-B and Mav-C. Sixteen of 17 isolates of the Mav-B sequevar were from HIV-positive patients; the Mav-A sequevar included six and five isolates from HIV-positive and HIV-negative individuals, respectively, as well as the two environmental isolates and the M. avium reference strain ATCC 35712; only one isolate, from a HIV-infected patient, belonged to the Mav-C sequevar. IS1245-RFLP analysis of M. avium isolates of sequevars Mav-A and Mav-B showed that isolates occurring in clusters of identical or highly related RFLP patterns generally belong to the same sequevar, and that M. avium strains belonging to the same sequevar may present distinct and unrelated IS1245-RFLP patterns. The question of the molecular markers specific for M. avium clones pathogenic for man is discussed.

Abstract
Systemic lupus erythematosus (SLE) has been described by many authors as a multisystem disorder involving variable and protean clinical manifestations and with an unpredictable course. We report the case of a 68-year-old woman suffering from SLE in whom tremor appeared ten years before a clinical picture suggestive of SLE and which remained the only clinical neurological sign even during overt disease. Tremor and other SLE manifestations disappeared with corticosteroid therapy.

Abstract
We describe four patients with Churg-Strauss syndrome admitted to the hospital in 1988. Some clinical and histological features of particular relief are present in these cases. All patients had been treated with corticosteroids and they are now in remission. Our work suggests that Churg-Strauss syndrome is not a rare disease and that an early diagnosis and appropriate therapy may influence favourably at least long term survival.

Abstract
The Authors report a case of eosinophilic cellulitis (Wells' syndrome). The patient was a 61 year old woman, diabetic, with a cardio-respiratory insufficiency and a maniaco-depressive psycosis. She presented, on the upper arms and trunk, a cutaneous eruption of erythematous-urticarial plaques, that histopathologically were characterized by a dermic leukocyte population, with a prevalence of eosinophils, distributed in the perivascular site. Laboratory tests revealed eosinophilia and circulating immune complexes. The etiopathogenesis of the disease is discussed as is the possible role of immune complexes in eosinophilic cellulitis.

Abstract
Sequential or simulatineous use is made of four types of antiproliferative drugs in the modern treatment of malignant lymphoma: alkylating drugs, including procarbazine; Vinca rosea alkaloids; antibiotics; corticosteroids. The simulataneous employment of two or more drugs appears to give best results, though it cannot eradicate the disease; this is possible with radiation or surgery in the early stages. Chemotherapy is nevertheless without alternative in the more advanced stages. Long periods of even complete remission may thus be achieved.

Abstract
A case of Hodgkin's disease confined to the spleen is described. A picture of sepsis with rapidly progessive cachexia was present from the outset. Necrosy revealed no gross evidence of the disease and diagnosis was solely dependent on the histological evidence.
