    Notes: Abstract Phase noise due to thermodynamic fluctuations in the optical path length is evaluated in this paper for basic fibre interferometers. In Mach-Zehnder and Michelson interferometers, where the temperature phase fluctuation (TPF) is that intrinsic to the fibre, this noise has been reported to be comparable to shot noise and a possible limit to sensor sensitivity in practical cases. We show that in Sagnac interferometers, used in fibre gyro and in Faraday current sensors, the TPF noise is decreased with respect to that intrinsic to the fiber because propagation in the same optical path leads to a correlation of the phase fluctuations. In addition, we show that in Fabry-Perot and ring resonators, as multiple reflections increase the effective path length, TPF noise is enhanced and can be dominant over shot noise even for moderate fibre lengths.

    Notes: Abstract With reference to squeezed states, we analyse the noise performances of the basic detection schemes in fibre telecommunications and interferometry. We have developed a semiclassical approach that allows us to translate the quantum mechanical formalism into synthetic expressions and rules only involving directly measurable physical quantities. As a result, we find that in the telecommunication field squeezed states do not allow significant improvements in system performances: in practice, the signal-to-noise ratio cannot be increased in standard detection schemes, both direct and coherent, by squeezing either the signal (because of propagation losses) or by the local oscillator. On the contrary, a significant improvement can be obtained in interferometric measurements if squeezed vacuum is coupled into the normally unused beamsplitter port.

    Notes: Abstract An analysis of the propagation process in fog has been performed by means of the Monte Carlo method. The effect of multiple scattering on image quality and on visibility range has been studied, together with the detailed time dependence of the light at the receiving system. The improvement in visibility achievable with range gating techniques has been evaluated.

    Notes: Abstract Main mechanisms involved in the development of chemotherapy-induced anemia are the direct bone marrow damage and the renal impairment with a secondary deficient production of erythropoietin. The first mechanism is induced by almost all cytotoxic drugs whilst the second one has been demonstrated with cisplatin treatment. NSCLC patients are generally treated with platinum-based chemotherapy and then both mechanisms are involved in the development of anemia which can be, as a consequence, more frequent and more severe compared to other cancer patients. Chemotherapy regimens such as MVP (mitomycin, vindesine, platin), cisplatin–etoposide and cisplatin–teniposide induce grade ≥2 anemia in 64%, 46% and 83% of patients, respectively, with grade 3–4 anemia occurring in 29%, 15% and 24% of patients. New chemotherapy regimens are also associated with a high incidence of anemia. Carboplatin–paclitaxel induces grade 3–4 anemia in 34% of patients and 30% of patients need blood transfusions. Similarly, 33% of patients treated with cisplatin-gemcitabine require blood transfusions. Erythropoietin is able to correct anemia in nearly 60%–80% of patients receiving platinum-based chemotherapy and in nearly 40% of patients treated with regimens without platinum compounds, leading to a reduction in blood transfusion requirement. Moreover, erythropoietin is able to prevent anemia development in cancer patients. Due to the high incidence of anemia, erythropoietin may represent an important tool in the supportive care of NSCLC patients. Erythropoietin use is mainly limited by the economic cost and then efforts should be made to identify the subset of patients in whom this supportive therapy is cost-effective. Patient and disease characteristics, factors predicting the probability to be transfused as well as factors predicting the response to erythropoietin can be useful in selecting patients likely to benefit from erythropoietin therapy.

    Notes: Abstract Objective: To describe the use of drugs among Italian women during pregnancy and to compare it with other reports in Italy from the last 10 years. Methods: A random sample of women who delivered in 1995–1996 were interviewed with regard to the care they received during pregnancy, delivery and the post-natal period. Information on antenatal care included maternal reports on the use of drugs during pregnancy. Results: Of the 9004 women interviewed, 75% took at least one drug during pregnancy. Users took a median number of two drugs. Iron (51%) and vitamins (25%) dominate prescriptions throughout pregnancy. Fifteen percent of women reported treatment for threatened abortion and 27% for risk of pre-term delivery. The data do not differ from the drug exposure profile during pregnancy reported in other Italian studies. Logistic regression analysis of drug use (excluding haematologicals and nutritionals) shows an increased risk of usage for older women, the better educated, for those who reported health problems and those who had compulsory bed rest and/or hospitalisation during pregnancy. Conclusion: Seventy-five percent of the women reported use of at least one drug during pregnancy. Haematological and nutritional drugs are over prescribed. Although hormones have been clearly proven to be ineffective in preventing threatened abortion, the study shows an almost unchanged and out of date prescription pattern of progestational drugs. In order to avoid unnecessary exposure to potential risk, maternity care procedures should be reviewed and strictly related to an “evidence-based” approach.
