- Abstract
Background. The aim of this study is to valuate thè efficacy of cytoriductive surgical in females with ovarian carcinoma in advanced stadium, and to define thè role of this surgical for thè sur-vival of females with hepatic metastases. Methods. This is a retrospective study. 164 fe¬males with ovarian cancer in IV stadium was ex-amined. 64 females had hepatic metastasis. Ali patients had cytoriductive surgical. Results. The survival in thè patients without hepatic metastasis was 38 months if thè cytor-eduction was very good; it was 18.3 months if there is residuai disease. The survival in thè patients with hepatic metastasis was 50,1 months if thè cytoreduction was very good; it was 27 months if there is residuai disease. Conclusions. A very good surgical is very impor-tant for thè survival of patients with ovarian cancer in advanced stadium. This is true also in thè patients with hepatic metastases.

Asthma is a heterogeneous chronic inflammatory disease of the airways. The most prevalent form is atopic asthma, which is initiated by the exposure to (inhaled) allergens. Intermittent attacks of breathlessness, airways hyperresponsiveness, wheezing, coughing, and resultant allergen-specific immune responses characterize the disease. Nociceptin/OFQ-NOP receptor system is able to combine anti-hyperresponsiveness and immunomodulatory actions. In particular, N/OFQ is able to inhibit airways microvascular leakage and bronchoconstriction through a presynaptic and non-opioid mechanism of action that blocks tachykinin release. Moreover, it also acts on allergenic sensitization because it is able to modulate the immune response that triggers the development of airway hyperresponsiveness through an interaction on cell membranes of dendritic cells (DCs) that are generally responsible to start and sustain allergic T helper 2 (TH2)-cell responses to inhaled allergens in asthma. In asthmatic patients, sputum showed elevated N/OFQ levels that are related to increased eosinophil counts. The addition of exogenous N/OFQ in sputum obtained from patients with severe asthma attenuated eosinophils migration and release of inflammatory mediators. These observations confirmed that elevated endogenous N/OFQ levels in asthmatic sputum were lower than the ones required to exert beneficial effects, suggesting that supplementation with exogenous N/OFQ may need. In conclusion, the innovative role of N/OFQ in counteracting airways inflammation/hyperresponsiveness opens new potential targets/strategies in asthma treatment.

- Abstract
Objective: Adjuvants or alternatives to antibiotics in urinary tract infections (UTIs) during pregnancy seem advisable because of possible fetal stress. The present study assessed the effectiveness of a food supplement containing L-methionine and Hibiscus sabdariffa L. and Boswellia serrata Roxb. extracts as a treatment for symptomatic UTIs in pregnancy., Design: Pregnant patients with symptomatic cystitis were screened for UTIs in three different clinical centers. Those unwilling to take antibiotics were offered two alternative treatments: (A) a 1-week treatment with the food supplement or (B) a week in which they were advised to increase their fluid consumption to more than 1.5 L daily. After 1 week, group B patients who still had positive urine cultures (UCs) or had no UC performed took the food supplement for an additional week. UCs were performed on all patients at the first visit (w0) and on most of them at 7 days (w1). Patients who were still positive at w1 or had no UC performed at w1 had UC performed 14 days (w2) thereafter., Results: Of 264 pregnant women enrolled, 216 joined group A, while 48 joined group B. At w1, 70.0% of group A patients and 43.2% of those in group B had negative UCs (p = 0.003). The reduction of bacterial load was 42.2% ± 8.0% and 4.5% ± 9.2%, respectively (p < 0.0001). At w1, symptoms disappeared in 135 patients (62.5%) in group A and 22 patients (45.8%) in group B (p = 0.03). At w2, 30 of 32 group B patients who switched to taking the supplement for the second week had negative UCs, including 20 who had been positive at w1. At w2, all group A patients had negative UCs. No side effects were reported., Conclusions: The food supplement provided effective treatment and might be an adjuvant or alternative to antibiotic therapy of symptomatic UTI in pregnancy.

- Abstract
Liposomes formulated with dimyristoyl-sn-glycero-phosphatidylcholine, DMPC, and either one of the cationic gemini surfactants (S,S)-2,3-dimethoxy-1,4-bis(N-hexadecyl-N,N-dimethylammonio)butane bromide, 1a, and (S,R)-2,3-dimethoxy-1,4-bis(N-hexadecyl-N,N-dimethylammonio)butane bromide, 1b, were investigated as vehicles of the photosensitizer m-tetrahydroxyphenylchlorin, m-THPC, to cell models of malignant glioma. The delivery efficiency of DMPC/1a and DMPC/1b liposome formulations were evaluated on the murine glioblastoma cell line C6 and on the human glioblastoma cell line LN229 by flow cytometry and laser scanning confocal microscopy. The stereochemistry of the spacer of the gemini was found to strongly influence the delivery efficiency of m-THPC to cells, the mode of interaction with the cell membrane, and the intracellular distribution of m-THPC. The physicochemical features of liposomes were investigated with the aim of explaining the parameters that control their biological features. Differences that could account for the different biological activity of the formulations concern the values of surface potential and the environment of m-THPC at the water/liposome interface.

- Abstract
Background: The aim of the present study was to compare the laparoscopic second-look with laparotomic second-look as regards the consistency of diagnosis of residual tumoral disease after first step treatment in patients affected by ovarian cancer, and to evaluate the feasibility of the laparoscopic second-look., Methods: Twenty-one patients affected by ovarian cancer underwent laparoscopic second-look followed by laparotomic second-look. Six months after the first surgical intervention all the patients showed no contraindications to laparoscopic second-look. All the surgeries were performed with the same procedure: after the introduction of the trocars the lysis of adherences was carried out, the whole abdominal cavity was explored, 18 abdominal-pelvic sites were examined, direct biopsies were performed and samples for the cyto- and histological analysis were obtained., Results: Positive predictive value for laparoscopy was 100% (6 out of 6 cases), while negative predictive value was 84% (2 false negative cases out of 12). The complete abdominal-pelvic examination was possible in 95% of cases with laparotomy while in 41% of cases with laparoscopy, because of post-operative severe adherences., Conclusions: Laparoscopic second-look has a good consistency as regards the diagnosis of residual tumoral disease, but its feasibility is lower than laparotomy owing to the presence of severe adherences and the high risk of intra- and post-operative compliances.
