Abstract
Objectives Proximal humerus fractures account for four-five % of all fractures. Shoulder hemiarthroplasty is indicated for complex fractures with high complication rates when treated with ORIF. This study aims to evaluate the correlation between the proper intraoperative tuberosity reduction, and the mid-to-long-term clinical outcome in a series of patients treated with hemiarthroplasty after proximal humerus fracture. Methods Forty-one patients with proximal humerus fractures who underwent hemiarthroplasty surgery between July 2009 and December 2019 were retrospectively reviewed. Quantitative analysis of the reduction of the tuberosities was performed on postoperative X-rays focusing on the distance between reconstructed greater tuberosity and the apex of the head of the prosthesis, (head-tuberosity distance), and contact between tuberosity and humerus diaphysis. The University of California Los Angeles Score (UCLA) was calculated for each patient. Results The mean time to surgery was 6.29 ± 2.8 days (range 2-18 days). Nine patients out of 41 (22%) had non anatomic tuberosity, and 32 (78%) were anatomic reduced. The UCLA score at the final follow-up was good and excellent (≥27) in 27 patients (66%), and poor (<27) in 14 (34%). A significant correlation was observed between proper tuberosity reduction and good/excellent UCLA scores (P<0.001). Conclusion Hemiarthroplasty is a valid and reliable technique for the treatment of proximal humerus fracture not eligible for internal fixation, with high risk of failure. The proper tuberosity reconstruction, paying special attention to the HTD and the contact between the cortical of the humeral diaphysis and the reconstructed tuberosity, is essential to reach a good clinical outcome.

Abstract
Patients with autosomal dominant (AD) hyper-IgE syndrome (HIES) suffer from a constellation of manifestations including recurrent bacterial and fungal infections, severe atopy, and skeletal abnormalities. This condition is typically caused by monoallelic dominant-negative (DN) STAT3 variants. In 2020, we described 12 patients from eight kindreds with DN IL6ST variants resulting in a new form of AD HIES. These variants encoded truncated GP130 receptors, with intact extracellular and transmembrane domains, but lacking the intracellular recycling motif and the four STAT3-binding residues, resulting in an inability to recycle and activate STAT3. We report here two new DN variants of IL6ST in three unrelated families with HIES-AD. The biochemical and clinical impacts of these variants are different from those of the previously reported variants. The p.(Ser731Valfs*8) variant, identified in seven patients from two families, lacks the recycling motif and all the STAT3-binding residues, but its levels on the cell surface are only slightly increased and it underlies mild biological phenotypes with variable clinical expressivity. The p.(Arg768*) variant, identified in a single patient, lacks the recycling motif and the three most distal STAT3-binding residues. This variant accumulates at the cell surface and underlies severe biological and clinical phenotypes. The p.(Ser731Valfs*8) variant shows that a DN GP130 expressed at near normal levels on the cell surface can underlie heterogeneous clinical presentations, ranging from mild to severe. The p.(Arg768*) variant demonstrates that a truncated GP130 protein retaining one STAT3-binding residue can underlie severe HIES.

Abstract
BACKGROUND Glecaprevir and Pibrentasvir (G/P) determine high rates of sustained virological response (SVR) with optimal safety profile in patients with chronic hepatitis C virus (HCV) infection. The efficacy and safety of G/P in Caucasian patients aged 75 years and older have not been widely analysed. METHODS This is a retrospective multicentre real-world study enrolling all consecutive patients 75 years and older who received G/P between October 2017 and January 2022 at five referral centres in Italy. SVR was analysed by intention-to-treat (ITT) and per-protocol analyses (PP). RESULTS A total of 570 patients met the inclusion criteria and were analysed: mean age was 80 (75-97) years, 356 (62%) were females, 52% (298/570) had HCV-1, 44% (252/570) had HCV-2 and 137 (24%) patients had liver cirrhosis. Four hundred and sixty-three (81%) patients were taking at least one concomitant drug, with 144 (25%) taking ≥5 concomitant drugs. G/P was given for 8 weeks in 488 patients (86%). During treatment, 48 patients (8%) reported side effects, with 10 (2%) patients discontinuing treatment prematurely. Two patients developed treatment-unrelated serious adverse events. Overall, the SVR rate was 97.9% (558/570) by ITT analysis and 99.6% (558/560) by PP analysis. SVR rates remained consistently high among subgroup analysis stratified by genotype, treatment duration, fibrosis stage and concomitant medications. CONCLUSIONS Treatment with G/P achieved 97.9% SVR rates in HCV patients older than 75 years of age. Safety was optimal with only 2% of patients discontinuing early.

Abstract
Patients with inherited CARMIL2 or CD28 deficiency have defective T cell CD28 signaling, but their immunological and clinical phenotypes remain largely unknown. We show that only one of three CARMIL2 isoforms is produced and functional across leukocyte subsets. Tested mutant CARMIL2 alleles from 89 patients and 52 families impair canonical NF-κB but not AP-1 and NFAT activation in T cells stimulated via CD28. Like CD28-deficient patients, CARMIL2-deficient patients display recalcitrant warts and low blood counts of CD4+ and CD8+ memory T cells and CD4+ TREGs. Unlike CD28-deficient patients, they have low counts of NK cells and memory B cells, and their antibody responses are weak. CARMIL2 deficiency is fully penetrant by the age of 10 yr and is characterized by numerous infections, EBV+ smooth muscle tumors, and mucocutaneous inflammation, including inflammatory bowel disease. Patients with somatic reversions of a mutant allele in CD4+ T cells have milder phenotypes. Our study suggests that CARMIL2 governs immunological pathways beyond CD28.

Abstract
BACKGROUND & AIMS Obeticholic acid (OCA) has recently been restricted in patients with primary biliary cholangitis (PBC) with "advanced cirrhosis" because of its narrow therapeutic index. We aimed to better define the predicting factors of hepatic serious adverse events (SAEs) and non-response in cirrhotic patients undergoing OCA therapy. METHODS Safety and efficacy of treatment were evaluated in a cohort of consecutive PBC cirrhotic patients started with OCA. OCA response was evaluated according to the Poise criteria. Risk factors for hepatic SAEs and non-response were reported as risk ratios (RR) with 95% confidence intervals (CIs). RESULTS One hundred PBC cirrhotics were included, 97 Child-Pugh class A and 3 class B. Thirty-one had oesophageal varices and 5 had a history of ascites. Thirty-three per cent and 32% of patients achieved a biochemical response at 6 and 12 months respectively. Male sex (adjusted-RR 1.75, 95%CI 1.42-2.12), INR (1.37, 1.00-1.87), Child-Pugh score (1.79, 1.28-2.50), MELD (1.17, 1.04-1.30) and bilirubin (1.83, 1.11-3.01) were independently associated with non-response to OCA. Twenty-two patients discontinued OCA within 12 months: 10 for pruritus, 9 for hepatic SAEs (5 for jaundice and/or ascitic decompensation; 4 for upper digestive bleeding). INR (adjusted-RR 1.91, 95%CI 1.10-3.36), lower albumin levels (0.18, 0.06-0.51), Child-Pugh score (2.43, 1.50-4.04), history of ascites (3.5, 1.85-6.5) and bilirubin (1.30, 1.05-1.56), were associated with hepatic SAEs. A total bilirubin≥1.4 mg/dl at baseline was the most accurate biochemical predictor of hepatic SAEs under OCA. CONCLUSIONS An accurate baseline assessment is crucial to select cirrhotic patients who can benefit from OCA. Although OCA is effective in one third of cirrhotics, bilirubin level ≥1.4 mg/dl should discourage from its use.

Abstract
AIM This study aims to highlight the importance of early diagnosis, timing, optimal treatment sequence and multidisciplinary approach as key factors in the orthodontic management of impacted and retained teeth associated with odontomas. METHODS Literature about classification, epidemiology, aetiopathogenesis, histopathology and therapeutic options about odontomas and impacted teeth in orthodontics was reviewed. Two case reports are presented, showing different timing in diagnosis and surgical removal of odontomas and some biomechanical approaches. CONCLUSION An early removal of the odontoma is certainly a more effective and simpler procedure in the approach to this problem.

Abstract
Ruptures of the extensor apparatus can have different etiologies and be complicated by underlying situations. Direct repair is not always possible, and reconstruction procedures can be insufficient, which leads to the appearance of multiple augmentation techniques to improve the strength of these constructs. Despite the proven results of these techniques, numerous procedures are described without any gold standard. We present our augmentation method for repairing the knee extensor apparatus with a vascular prosthesis that facilitates healing, does not interfere with the primary procedure, has no donor morbidity or rejection risk, and allows earlier mobilization and rehabilitation. The technique was used in different cases with multiple etiologies that needed reinforcement, with promising results.

Abstract
BACKGROUND The aim of this study was to evaluate the results of different treatments for pelvic Osteoblastoma (OB). METHODS We retrospectively evaluated 34 patients affected by primary pelvic OB from 3 oncologic referral centers. Patients with a minimum follow-up of 24 months were included. Local recurrence (LR) rate and complications were recorded. RESULTS The primary treatment was radio-frequency ablation (RFA) in 4 patients (11.8%), curettage (ILC) in 21 (61.7%) and resection (EBR) in 9 (26.5%). Mean follow-up was 8.9 years (SD ± 6.6). Local recurrence free survival (LRFS) rate after primary surgery was 79.4% at 3 and 5 years. In details, LRFS rate at 3 and 5 years was 50.0% in RFA, 81.0% in ILC and 88.9% in EBR. Post-operative complications occurred in 6/34 patients (17.7%), in particular after EBR. CONCLUSIONS RFA is the least invasive technique to treat OB but with high LR rate. Thus, it should be reserved to very small lesions. ILC is a suitable treatment for stage II OB. For stage III OB, EBR is the treatment of choice, despite an increased risk of complications. For selected stage III OB (relatively small, periacetabular area) ILC might be considered.

Abstract
BACKGROUND Delirium is thought to be common across various settings of care; however, still little research has been conducted in rehabilitation. AIM We investigated the prevalence of delirium, its features and motor subtypes in older patients admitted to rehabilitation facilities during the three editions of the "Delirium Day project". METHODS We conducted a cross-sectional study in which 1237 older patients (age ≥ 65 years old) admitted to 50 Italian rehabilitation wards during the three editions of the "Delirium Day project" (2015 to 2017) were included. Delirium was evaluated through the 4AT and its motor subtype with the Delirium Motor Subtype Scale. RESULTS Delirium was detected in 226 patients (18%), and the most recurrent motor subtype was mixed (37%), followed by hypoactive (26%), hyperactive (21%) and non-motor one (16%). In a multivariate Poisson regression model with robust variance, factors associated with delirium were: disability in basic (PR 1.48, 95%CI: 1.17-1.9, p value 0.001) and instrumental activities of daily living (PR 1.58, 95%CI: 1.08-2.32, p value 0.018), dementia (PR 2.10, 95%CI: 1.62-2.73, p value < 0.0001), typical antipsychotics (PR 1.47, 95%CI: 1.10-1.95, p value 0.008), antidepressants other than selective serotonin reuptake inhibitors (PR 1.3, 95%CI: 1.02-1.66, p value 0.035), and physical restraints (PR 2.37, 95%CI: 1.68-3.36, p value < 0.0001). CONCLUSION This multicenter study reports that 2 out 10 patients admitted to rehabilitations had delirium on the index day. Mixed delirium was the most prevalent subtype. Delirium was associated with unmodifiable (dementia, disability) and modifiable (physical restraints, medications) factors. Identification of these factors should prompt specific interventions aimed to prevent or mitigate delirium.

Abstract
Introduction Delirium and sarcopenia are common, although underdiagnosed, geriatric
syndromes. Several pathological mechanisms can link delirium and low skeletal muscle mass, but few studies have investigated their association. We aimed to investigate (1) the association between delirium and low skeletal muscle mass and (2) the possible role of calf circumference mass in finding cases with delirium. Methods The analyses were conducted employing the cross-sectional “Delirium Day” initiative, on patient 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes and hospices in Italy in 2017. Delirium was diagnosed as a 4 + score at the 4-AT scale. Low skeletal muscle mass was operationally defined as calf circumference ≤ 34 cm in males and ≤ 33 cm in females. Logistic regression models were used to investigate the association between low skeletal muscle mass and delirium. The discriminative ability of calf circumference was evaluated using non-parametric ROC analyses. Results A sample of 1675 patients was analyzed. In total, 73.6% of participants had low skeletal muscle mass and 24.1% exhibited delirium. Low skeletal muscle mass and delirium showed an independent association (OR: 1.50; 95% CI 1.09–2.08). In the subsample of patients without a diagnosis of dementia, the inclusion of calf circumference in a model based on age and sex significantly improved its discriminative accuracy [area under the curve (AUC) 0.69 vs 0.57, p < 0.001]. Discussion and conclusion Low muscle mass is independently associated with delirium. In patients without a previous diagnosis of dementia, calf circumference may help to better identify those who develop delirium.

Abstract
Biofilms confine bacterial cells within self-produced matrices, offering advantages such as protection from antibiotics and entrapment of nutrients. Polysaccharides are major components in these macromolecular assemblies, and their interactions with other chemicals are of high relevance for the benefits provided by the biofilm 3D molecular matrix. NMR is a powerful technique for the study and characterization of the interactions between molecules of biological relevance. In this study, we have applied multifrequency saturation transfer difference (STD) NMR and DOSY NMR approaches to elucidate the interactions between the exopolysaccharide produced by Burkholderia multivorans C1576 (EpolC1576) and the antibiotics kanamycin and ceftadizime. The NMR strategies presented here allowed for an extensive characterization at an atomic level of the mechanisms behind the implication of the EpolC1576 in the recalcitrance phenomena, which is the ability of bacteria in biofilms to survive in the presence of antibiotics. Our results suggest an active role for EpolC1576 in the recalcitrance mechanisms toward kanamycin and ceftadizime, though through two different mechanisms.

Abstract
Real-world evidence on the course of Hepatitis C Virus (HCV) chronic liver disease after Sustained Virologic Response (SVR) obtained with direct-acting antiviral drugs (DAAs) are still limited, and the effects on mortality remain unclear. We evaluated the post-treatment survival of 4307 patients in the RESIST-HCV cohort (mean age 66.3 ± 11.6 years, 56.9% males, 24.7% chronic hepatitis, 66.9% Child-Pugh A cirrhosis and 8.4% Child-Pugh B cirrhosis) treated with DAAs between March 2015 and December 2016 and followed for a median of 73 weeks (range 16-152). Proportional cause-specific hazard regression for competing risks was used to evaluate the survival and to assess the predictors of liver and cardiovascular death. Overall, 94.7% of patients achieved SVR while 5.3% were HCV RNA-positive at last follow-up. Sixty-three patients (1.4%) died during the observation period. SVR was associated with a decreased risk of liver mortality (hazard ratio,HR0.09, beta -2.37, p < .001). Also, platelet count (HR 0.99, beta-0.01, p = .007) and albumin value (HR 0.26, beta -1.36 p = .001) were associated with liver mortality by competing risk analysis. SVR was associated with a reduced risk of cardiovascular mortality regardless of presence of cirrhosis (HR 0.07, beta-2.67, p < .001). Presence of diabetes (HR 3.45, beta 1.24, p = .014) and chronic kidney disease class ≥3 (HR 3.60, beta 1.28, p = 0.016) were two factors independently associated with higher risk of cardiovascular mortality. Patients with SVR to a DAA therapy have a better liver and cardiovascular survival, and the effects of HCV eradication are most evident in patients with compensated liver disease.

Ectopic pregnancies occur in about 1-2 % of all pregnancies, with a high rate of maternal mortality due to bleeding caused by the rupture of the ectopic pregnancy. Ipsilateral ectopic pregnancy on a tubal remnant after salpingectomy is rare and it is associated with a higher mortality rate when compared to other ectopic pregnancies. Diagnosis and treatment of these pregnancies can be difficult, requiring a multidisciplinary management to plan the best treatment for the patient. The objective of this video is to show the laparoscopic removal of a tubal pregnancy on the stump of a previous salpingectomy with the application of three laparoscopic rings/endoloops ® to isolate the tubal portion from the uterus.

Abstract
BACKGROUND & AIMS Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is responsible for coronavirus disease 2019 (COVID-19), which in males, especially in advanced age, can sometimes evolve into acute respiratory distress syndrome. In addition, mild to moderate alterations in liver function tests (LFTs) have been reported in the worst affected patients. Our review aims to analyse data on the incidence and prognostic value of LFT alterations, the underlying mechanisms and the management of pre-existing liver disease in COVID-19 affected patients. METHODS We searched available literature through online PubMed database using terms as "SARS-CoV-2," "Liver damage," "Liver Function tests," "COVID-19," "pre-existing liver disease," "drug-induced liver injury." RESULTS Available evidence suggest that there could be a relationship between SARS-CoV-2 infection and liver damage, although the underlying involved mechanism remains unclear. Cohort studies have shown that high ALT levels, low platelet counts and low albumin levels at admission and during hospitalisation are associated with a high mortality rate. Unfortunately, little is known about the impact of COVID-19 on pre-existing liver damage. While chronic viral infections or NAFLD are associated with an increased risk of COVID-19 progression, patients with cirrhosis may have increased susceptibility to SARS-CoV-2 infection due to their systemic immunocompromised status. DILI seems common among hospitalised patient with severe pneumonia. CONCLUSION Mild to moderate liver impairment during Covid-19 is common, especially in patients with pre-existing liver disease. Further studies should be performed in order to understand how pre-existing liver conditions may influence and worsen progression of liver disease in COVID-19 patients.

Abstract
Background/Aims Patients with genotype 3 hepatitis C virus (G3-HCV) cirrhosis are very difficult to treat compared to patients with other HCV genotypes. The optimal treatment duration and drug regimen associated with ribavirin (RBV) remain unclear. To evaluate the efficacy and safety of daclatasvir (DCV)/sofosbuvir (SOF) plus a flat dose of 800 mg RBV (flat dose) compared to DCV/SOF without RBV or DCV/SOF plus an RBV dose based on body weight (weight-based) in G3-HCV patients with compensated or decompensated cirrhosis. Methods We analyzed data for 233 G3 cirrhotic patients. Of these, 70 (30%), 87(37%) and 76 (33%) received SOF/DCV, SOF/DCV/RBV flat dose, and SOF/DCV/RBV weight-based dose, respectively. Treatment duration was 24 weeks. Sustained virological response (SVR) was evaluated at week 12 posttreatment (SVR12). Results Overall, SVR12 was achieved in 220 out of 233 patients (94.4%). The SVR12 rate was lower in the DCV/SOF group than in the DCV/SOF/RBV flat-dose group and the DCV/SOF/RBV weight-based group (87.1% vs 97.7% and 97.4%, respectively, p=0.007). A higher incidence of anemia occurred in the DCV/SOF/RBV weight-based group compared to those in the other two groups (p<0.007). Conclusions We found that the DCV/SOF/RBV flat-dose regimen is an effective treatment in terms of efficacy and safety in patients with G3-HCV compensated or decompensated cirrhosis. Therefore, antiviral regimens without RBV should be restricted only to naïve patients with G3-HCV compensated cirrhosis who have a clear contraindication for RBV.

Abstract
Biofilms are aggregates of microbial cells encased in a highly hydrated matrix made up of self-produced extracellular polymeric substances (EPS) which consist of polysaccharides, proteins, nucleic acids, and lipids. While biofilm matrix polysaccharides are unraveled, there is still poor knowledge about the identity and function of matrix-associated proteins. With this work, we performed a comprehensive proteomic approach to disclose the identity of proteins associated with the matrix of biofilm-growing Burkholderia multivorans C1576 reference strain, a cystic fibrosis clinical isolate. Transmission electron microscopy showed that B. multivorans C1576 also releases outer membrane vesicles (OMVs) in the biofilm matrix, as already demonstrated for other Gram-negative species. The proteomic analysis revealed that cytoplasmic and membrane-bound proteins are widely represented in the matrix, while OMVs are highly enriched in outer membrane proteins and siderophores. Our data suggest that cell lysis and OMVs production are the most important sources of proteins for the B. multivorans C1576 biofilm matrix. Of note, some of the identified proteins are lytic enzymes, siderophores, and proteins involved in reactive oxygen species (ROS) scavenging. These proteins might help B. multivorans C1576 in host tissue invasion and defense towards immune system assaults.

Abstract
Microorganisms often grow in communities called biofilms where cells are imbedded in a complex self-produced biopolymeric matrix composed mainly of polysaccharides, proteins, and DNA. This matrix, together with cell proximity, confers many advantages to these microbial communities, but also constitutes a serious concern when biofilms develop in human tissues or on implanted prostheses. Although polysaccharides are considered the main constituents of the matrices, their specific role needs to be clarified. We have investigated the chemical and morphological properties of the polysaccharide extracted from biofilms produced by the C1576 reference strain of the opportunistic pathogen Burkholderia multivorans, which causes lung infections in cystic fibrosis patients. The aim of the present study is the definition of possible interactions of the polysaccharide and the three-dimensional conformation of its chain within the biofilm matrix. Surface plasmon resonance experiments confirmed the ability of the polysaccharide to bind hydrophobic molecules, due to the presence of rhamnose dimers in its primary structure. In addition, atomic force microscopy studies evidenced an extremely compact three-dimensional structure of the polysaccharide which may form aggregates, suggesting a novel view of its structural role into the biofilm matrix.

Abstract
BACKGROUND & AIMS The effectiveness of direct-acting antivirals (DAAs) against hepatitis C virus (HCV), following successful treatment of early hepatocellular carcinoma (HCC), has been studied extensively. However, the benefit in terms of overall survival (OS) remains to be conclusively demonstrated. The aim of this study was to assess the impact of DAAs on OS, HCC recurrence, and hepatic decompensation. METHODS We prospectively enrolled 163 consecutive patients with HCV-related cirrhosis and a first diagnosis of early Barcelona Clinic Liver Cancer stage 0/A HCC, who had achieved a complete radiologic response after curative resection or ablation and were subsequently treated with DAAs. DAA-untreated patients from the ITA.LI.CA. cohort (n = 328) served as controls. After propensity score matching, outcomes of 102 DAA-treated (DAA group) and 102 DAA-untreated patients (No DAA group) were compared. RESULTS In the DAA group, 7/102 patients (6.9%) died, HCC recurred in 28/102 patients (27.5%) and hepatic decompensation occurred in 6/102 patients (5.9%), after a mean follow-up of 21.4 months. OS was significantly higher in the DAA group compared to the No DAA group (hazard ratio [HR] 0.39; 95% CI0.17-0.91; p = 0.03). HCC recurrence was not significantly different between the DAA and No DAA groups (HR0.70; 95% CI0.44-1.13; p = 0.15). A significant reduction in the rate of hepatic decompensation was observed in the DAA group compared with the No DAA group (HR0.32; 95% CI0.13-0.84; p = 0.02). In the DAA group, sustained virologic response was a significant predictor of OS (HR 0.02; 95% CI 0.00-0.19; p <0.001), HCC recurrence (HR 0.25; 95% CI 0.11-0.57; p <0.001) and hepatic decompensation (HR 0.12; 95% CI 0.02-0.38; p = 0.02). CONCLUSIONS In patients with HCV-related cirrhosis who had been successfully treated for early HCC, DAAs significantly improved OS compared with No DAA treatment. LAY SUMMARY We aimed to determine whether direct-acting antivirals (DAAs) significantly improve overall survival in patients with hepatitis C virus-related compensated cirrhosis and a first diagnosis of hepatocellular carcinoma (HCC) which has been successfully treated with curative resection or ablation. Using propensity-score matched patients, we found that DAAs improved overall survival and reduced the risk of hepatic decompensation. However, the risk of HCC recurrence was not significantly reduced.

Abstract
BACKGROUND & AIMS Studies have produced conflicting results of the incidence of hepatocellular carcinoma (HCC) in patients with hepatitis C virus-associated cirrhosis treated with direct-acting antivirals (DAAs). Data from clinics are needed to accurately assess the occurrence rate of HCC in patients with cirrhosis in the real world. METHODS We collected data from a large prospective study of 2,249 consecutive patients (mean age = 65.4 years, 56.9% male) with hepatitis C virus-associated cirrhosis (90.5% with Child-Pugh class A and 9.5% with Child-Pugh class B) treated with DAAs from March 2015 through July 2016 at 22 academic and community liver centers in Sicily, Italy. HCC occurrence was evaluated by Kaplan-Meier curves. Cox regression analysis was used to identify variables associated with HCC development. RESULTS A sustained virologic response (SVR) was achieved by 2,140 patients (total = 95.2%; 95.9% with Child Pugh class A and 88.3% with Child Pugh class B; P < .001). Seventy-eight patients (3.5%) developed HCC during a mean follow-up of 14 months (range = 6-24 months). At 1 year after exposure to DAAs, HCC developed in 2.1% of patients with Child-Pugh class A with an SVR and 6.6% of patients with no SVR and in 7.8% of patients with Child-Pugh class B with an SVR and 12.4% of patients with no SVR (P < .001 by log-rank test). Albumin level below 3.5 g/dL (hazard ratio = 1.77, 95% confidence interval = 1.12-2.82, P = .015), platelet count below 120 × 109/L (hazard ratio = 3.89, 95% confidence interval = 2.11-7.15, P < .001), and absence of an SVR (hazard ratio = 3.40, 95% confidence interval = 1.89-6.12, P < .001) were independently associated increased risk for HCC. The mean interval from exposure to DAAs to an HCC diagnosis was 9.8 months (range = 2-22 months) and did not differ significantly between patients with (n = 64, 9.2 months) and without (n = 14, 12.0 months) an SVR (P = .11). A larger proportion of patients with an SVR had a single HCC lesion (78% vs 50% without an SVR; P = .009) or an HCC lesion smaller than 3 cm (58% vs 28% without an SVR; P = .07). CONCLUSIONS In an analysis of data from a large prospective study of patients with hepatitis C virus-associated compensated or decompensated cirrhosis, we found that the SVR to DAA treatment decreased the incidence of HCC over a mean follow-up of 14 months.

Abstract
BACKGROUND Data on HCV-related hepatocellular carcinoma (HCC) early recurrence in patients whose HCC was previously cured, and subsequently treated by direct-acting antivirals (DAAs), are equivocal. AIM To assess the risk of HCC early recurrence after DAAs exposure in a large prospective cohort of HCV-cirrhotic patients with previous successfully treated HCC, also looking for risk factors for cancer early recurrence. METHODS We enrolled 143 consecutive patients with complete response after curative treatment of HCC, subsequently treated with DAAs and monitored by the web-based RESIST-HCV database. Clinical, biological, and virological data were collected. The primary endpoint was the probability of HCC early recurrence from DAA starting by Kaplan-Meier method. RESULTS Eighty-six per cent of patients were in Child-Pugh class A and 76% of patients were BCLC A. Almost all patients (96%) achieved sustained virological response. Twenty-four HCC recurrences were observed, with nodular or infiltrative pattern in 83% and 17% of patients, respectively. The 6-, 12- and 18-month HCC recurrence rates were 12%, 26.6% and 29.1%, respectively. Main tumour size and history of prior HCC recurrence were independent risk factors for HCC recurrence by Cox multivariate model. CONCLUSIONS Probability of HCC early recurrence in patients who had HCC previously cured remains high, despite HCV eradication by DAAs. Risk was comparable but not higher to that reported in literature in DAA-untreated patients. Previous HCC recurrence and tumour size can be used to stratify the risk of HCC early recurrence. Further studies are needed to assess impact of DAAs on late recurrence and mortality.

Abstract
Miller Fisher syndrome (MFS) is considered to be an uncommon variant of Guillain-Barré Syndrome. The disease is clinically characterized by acute ataxia of limbs, areflexia and ophthalmoplegia, although the set of symptoms and signs can be quite heterogeneous, with a benign and monophasic course. We describe a case of recurrent MFS where there have been four clinical episodes occurred with complete remission after each relapse. Last recurrence was treated with oral steroids. The reported frequency of recurrent MFS in literature is variable as well as the best treatment in these cases. We add a new case treated with steroid and we perform a review of the literature.

Abstract
Biofilms are a collective mode of bacterial life in which a self-produced matrix confines cells in close proximity to each other. Biofilms confer many advantages, including protection from chemicals (including antibiotics), entrapment of useful extracellular enzymes and nutrients, as well as opportunities for efficient recycling of molecules from dead cells. Biofilm matrices are aqueous gel-like structures composed of polysaccharides, proteins, and DNA stabilized by intermolecular interactions that may include non-polar connections. Recently, polysaccharides extracted from biofilms produced by species of the Burkholderia cepacia complex were shown to possess clusters of rhamnose, a 6-deoxy sugar with non-polar characteristics. Molecular dynamics simulations are well suited to characterizing the structure and dynamics of polysaccharides, but only relatively few such studies exist of their interaction with non-polar molecules. Here we report an investigation into the hydrophobic properties of the exopolysaccharide produced by Burkholderia multivorans strain C1576. Fluorescence experiments with two hydrophobic fluorescent probes established that this polysaccharide complexes hydrophobic species, and NMR experiments confirmed these interactions. Molecular simulations to model the hydrodynamics of the polysaccharide and the interaction with guest species revealed a very flexible, amphiphilic carbohydrate chain that has frequent dynamic interactions with apolar molecules; both hexane and a long-chain fatty acid belonging to the quorum-sensing system of B. multivorans were tested. A possible role of the non-polar domains of the exopolysaccharide in facilitating the diffusion of aliphatic species toward specific targets within the biofilm aqueous matrix is proposed.

Abstract
OBJECTIVES To evaluate the morbidity, and the therapeutic value of surgery after chemoradiation in a large series of locally advanced cervical cancers (LACC). The prognostic role of different clinico-pathological factors has been also evaluated. METHODS Between October 1997 and October 2006, 161 LACC patients were treated at both the Gynecologic Oncology Units of the Catholic University of Rome and Campobasso. Radiotherapy was administered to the whole pelvic region in combination with cisplatin and 5-fluorouracil. Radical surgery was performed 5-6 weeks after the end of the treatment. RESULTS A clinical complete/partial response was observed in 153 patients and radical surgery was performed in 152 cases. The overall rate of surgical complications was 33% with 15 (10%) patients experiencing severe toxicities. At pathological examination 111 of 152 patients (73%) showed absent/microscopic residual disease. With a median follow-up of 28 months, the 5-year disease free-survival (DFS) was 83% and the 5-year overall survival (OS) 90%. Advanced FIGO (Federation Internationale de Gynecolgie et d'Obstetrique) stage, pathological response and lymph node involvement were found significantly associated with clinical outcome. CONCLUSIONS We confirmed in a larger series the safety and efficacy of this multimodal approach in the treatment of LACC. The pathological assessment of response can allow not only a tailored surgery in selected patients, but also the identification of patients with higher risk of recurrence to be submitted to adjuvant therapies.

Abstract
OBJECTIVES To investigate the blood flow within invasive cervical carcinoma by transvaginal two-dimensional (2D) color spectral Doppler and three-dimensional (3D) color power angiography and to correlate these parameters with the clinicopathological characteristics. METHODS Seventy-four patients with invasive cervical carcinoma were enrolled for the analysis. Squamous cell carcinoma serum antigen levels (SCC) were obtained for all the patients. Sections of all malignant tissues were analyzed for tumor expression of cyclooxygenase-2 (COX-2). All patients underwent color and spectral Doppler examination and 44 patients had 3D color power angiography. Color spectral Doppler parameters (color score, lowest resistance index (RI), highest peak systolic velocity (PSV)) and 3D color power angiography indices (relative color, average color, flow measure) of FIGO I/II cervical cancers were compared with those obtained in a control group of 24 patients with a normal uterine cervix. Pulsed Doppler parameters and the 3D vascular indices were compared with clinicopathological parameters, SCC serum antigen levels and tumor COX-2 expression. RESULTS At color Doppler analysis 72 patients (97%) showed intralesional detectable vessels. Color spectral Doppler and 3D-derived parameters were significantly different in FIGO I/II cervical cancers compared with those in women with a normal cervix. A significantly higher color score (P = 0.0008), lower RI (P = 0.032) and higher PSV (P = 0.004) were associated with a tumor diameter > or =4 cm compared with smaller tumors. The highest PSV was significantly higher in patients with FIGO stage III/IV compared with FIGO stage I/II (P = 0.0069). There was a direct correlation between PSV and SCC (r = +0.44, P = 0.003). The median relative color was significantly higher in patients with a higher color score (P = 0.0006). No statistically significant correlations were found between 3D color power angiography parameters and the clinicopathological characteristics or between the 3D vascular parameters and biological factors. CONCLUSIONS Alterations of 3D ultrasound-derived vascular indices were found in patients with cervical cancer compared with those with a normal cervix. Moreover, some vascular indices proved to be associated with tumor size. The assessment of a possible clinical role of 2D and 3D ultrasound-derived vascular indices in cervical cancer deserves further investigation.

Abstract
The in vitro interaction between the new antimetabolite gemcitabine (GEM) and topotecan (TPT) was analyzed in A2780 ovarian cancer cells. The growth inhibitory effect was assessed after 3 days of drug exposure. GEM and TPT obtained in vitro IC50 values of 2.1 +/- 0.9 and 33.7 +/- 10.2 nM, respectively. The interaction between GEM and TPT was evaluated by exposing cancer cells at increasing doses of GEM (0.1, 1, and 10 nM) and TPT (1, 10, 100, and 1000 nM). Analysis of data about the interaction between GEM and TPT was performed by applying the isobole method. An antagonistic effect was noticed when GEM was combined with TPT in the tested concentration range. DNA analysis was also performed and showed an augmentation of cells blocked in the G2/M phase during TPT exposure, while an increase of blocked cells in the G0/1, phase was observed after GEM treatment. This latter effect was predominant when the two drugs were used in combination. We also investigated the effect of sequential exposure to drugs, pretreating A2780 cells for 24 h with TPT and then for 48 h with GEM, and, conversely, pretreating A2780 cells with GEM for 24 h and thereafter with TPT for 48 h. Both these combined sequential treatments showed an antagonist effect of the drugs' combination. Long-term growth inhibition effect was established by clonogenic assay performed after 10 days of culture after drug treatment. Also these data confirmed the antagonistic effect between GEM and TPT in A2780 ovarian cancer cells.

Abstract
OBJECTIVE The aim of this study was to assess the association among the pathological status of different lymph node groups and parametrium in a single institutional population of 103 locally advanced cervical cancer (LACC) cases who underwent surgery after a neoadjuvant approach. A series of 29 early cervical cancer patients was also included in the analysis. METHODS Eighty-two LACC patients with documented clinical response to neoadjuvant treatment and 29 early stage cases underwent radical surgery. The operative technique consisted of a type II-V radical hysterectomy and systematic pelvic lymphadenectomy (median number of lymph nodes removed 46; range 5-140). Sixty-four cases were submitted to para-aortic lymphadenectomy up to the level of the inferior mesenteric artery (median number of lymph nodes removed 13; range 1-37). RESULTS Two subgroups of lymph nodes were defined: lower pelvic lymph nodes (LPN), including obturator and external iliac nodes, and upper pelvic nodes (UPN) including common iliac, presacral, and internal iliac nodes. Metastatic UPN involvement showed a strict association with LPN involvement: in LACC cases, 6 of 7 (86%) positive UPN cases had tumor disease at the LPN level. The single positive UPN case with negative LPN was intraoperatively identified by palpation and frozen section. Similarly, in early cervical cancer patients, 100% of positive UPN cases showed metastatic involvement at the LPN level. Sixty-three of 70 (90%) LACC patients with negative histological parametrium had negative LPN. Among 12 cases with metastatic involvement of parametrium, 5 cases (41.7%) had positive LPN. In early stage cervical cancer, 23 of 27 (85%) cases with negative parametrium showed no lymph nodal involvement. Intraoperative palpation of the parametrium could identify all cases with parametrial involvement not predicted by LPN status. CONCLUSIONS These data offer the basis for tailoring the extent of radical surgery in LACC patients, through the selection of those lymph node stations likely to provide reliable information on the pathological status of UPN and parametrium.

Abstract
Research focused on the development of new anticancer agents has been based mainly on the assessment of the antitumour activity. This yields a large number of newly developed drugs endowed with good antitumour properties, but heavy side-effects on myelopoiesis. In this work, we validate a new method potentially useful to assess myelotoxic effect of newly developed agents. The proposed technique uses peripheral blood CD34+ cells as source of haematopoietic progenitors. These cells are grown in liquid culture in the presence of cytokines able to induce differentiation versus the three main lineages. Doxorubicin, carboplatin and topotecan served as reference drugs to investigate the accuracy of the technique. The three drugs mimick the effects reported in vivo. Doxorubicin and carboplatin produce a specific effect toward erythropoietic and thrombopoietic lineages, respectively, and topotecan a three-lineage toxicity. An advantage of the technique is the possibility to further investigate myelotoxicity. Here, we assessed differentiation markers in CD34+ cells to evaluate if the three drug treatments can affect the process of differentiation. Data show that the drug treatments were unable to modulate the expression of the selected differentiation markers in the surviving population. We propose this method as an innovative tool to score the myelotoxic effect of compounds in the first steps of drug development to further develop those compounds with the best ratio between activity and myelotoxic effects. Moreover, the fact that the method is performed in liquid phase allows its optimisation in a conventional "high throughput system".

Abstract
PURPOSE Among flavonoids, chalcones have been identified as interesting compounds having chemopreventive and antitumor properties. We studied a panel of newly developed chalcone analogues (S1-S10) using MDA-MB 231 and MCF-7 ADRr breast cancer cells and the T-leukemic Jurkat cell line. Quercetin was used as the reference compound. METHODS Antiproliferative activity was evaluated by cell counts performed after 72 h of exposure to the drugs. DNA analysis and redox activity were evaluated using flow cytometry. Apoptosis was assessed by morphological analysis, using YOYO-1 as DNA dye; p-glycoprotein function was ascertained by quantitating the efflux of rhodamine 123. RESULTS All cells were sensitive to chalcone analogues yielding IC50 in micromolar concentrations with the following order regardless of the multidrug resistance (MDR) status: S1 > S2 > quercetin. S1 and S2, the most active compounds, were selected to evaluate their effect on the cell cycle, apoptosis, redox activity, and modulation of the p-glycoprotein function. No significant perturbation in cell cycle was seen with concentration up to 1 microM after 24 h. After 72 h a slight increase in G2/M block and DNA fragmentation occurred at 10 microM. Morphological analysis of apoptosis showed that chalcone analogues induced apoptosis to a higher extent than quercetin. Redox analysis demonstrated that all substances were able to increase intracellular thiol levels, which returned to baseline value after 24 h for all drugs except quercetin. Production of reactive oxygen species was essentially unaffected by all compounds. Finally, in MDR-positive MCF-7 ADRr cells chalcone analogues were unable to modulate p-glycoprotein function while quercetin was able to. CONCLUSIONS Newly developed S1 and S2 chalcones have a different but higher antitumor activity than quercetin and could be considered as potential new anticancer drugs.

Abstract
Taxanes antitumour agents such as paclitaxel and docetaxel represent a successful family of chemotherapeutic drugs. Unfortunately, acquired and innate resistance represents a clinical problem for these drugs. We investigated, on a panel of 7 human cancer cell lines, the growth inhibition effect of 3 newly developed taxanes (SB-T-1213, SB-T-1250 and SB-T-101187) with modification at the C10 and C3' positions of the taxane framework. These positions have been previously characterized as critical to make taxanes highly active against cells overexpressing the efflux pump P-glycoprotein (P-gp). Paclitaxel and docetaxel were used as reference compounds. Results unambiguously indicate the exceptional activity of the novel taxanes toward P-gp positive cells (up to >400 fold higher potency than that of paclitaxel). SB-T-1213 and SB-T-1250 are also substantially more active than the reference compounds against P-gp negative cells. To better understand the mechanisms underlying the enhanced activity of the newly developed taxanes, we performed cell cycle and apoptosis analysis. This study demonstrates that the striking growth inhibition effect exhibited by the novel taxanes is ascribed to their increased ability in inducing apoptosis and G(2)/M cell cycle block. SB-T-1213 and SB-T-1250 are also more active than reference compounds in inducing intracellular accumulation of the beta-tubulin subunits. Finally, it is revealed that these novel taxanes have ability to inhibit the function of the P-gp efflux pump on the basis of the Rhodamine 123 assay. These findings strongly suggest that SB-T-1213, SB-T-1250 and SB-T-101187 represent a new tool to overcome innate or acquired P-gp mediated taxane-resistance.

Abstract
We have summarized chemical, physical, and microbiological characteristics of Quaternary Ammonium Salts: particularly, benzalchromium chloride and didecyl-dimethyl-ammonium chloride characteristics were analyzed. These compounds may act as antimicrobial agents in different way: 1) they are surface-active agents and will denature protein or cause dissociation of an enzyme from its prosthetic group; 2) they may alter the cell permeability of bacteria and yeasts; 3) they may stimulate the glycolysis reaction and 4) may inhibit oxidation of lactate. These latest activities may play a role in maintenance of physiologic microbial ecology of vagina or in the re-establishment of the vaginal ecosystem after vaginitis or vaginosis. We have also summarized the physiologic variation of vaginal ecosystem during the different phases of women's life and the microbiology of vagina during vaginitis and vaginosis. The results of more recent studies about the therapeutic role of quaternary ammonium compounds in vulvo-vaginal infections an in vaginosis are synthetically reported. We concluded that quarternary ammonium compounds are efficacious, handy and safe, in obstetrics and gynecology. A very good compliance and low costs of these compounds suggest that they may be used alone as well in association with specific antimicrobial agents in the treatment of most of gynecological infections, and particularly in bacterial vaginosis.

Abstract
Disruption followed by intravasal embolization is a rare (0.5%) however possible complication secondary to the insertion of a central venous catheter. The carriers of these implantable systems are patients who, for their cure and at times even for their survival, require the chronic intravenous infusion of drugs and solutions. Therefore materials that can allow long-term insertion with a minimum of complications are the most suitable. There are several causes of disruption and embolization of cannulae. The most common are represented by the pinch-off syndrome and catheter disconnection from reservoir. The literature on the subject is illustrated and a personal case treated with intravascular retrieval is reported.

Abstract
The growth inhibitory effect of paclitaxel, docetaxel, and newly developed taxanes IDN5109, IDN5111, and IDN5127 was assessed on peripheral blood (PB) CD34+ maintained in liquid culture and on three human cancer cell lines (MDA-MB231, MCF-7 ADRr, CEM VBLr). Concomitantly, DNA analysis was also performed. For unfractionated peripheral blood progenitor cells (PBPC) toxicity was also assessed by clonogenic assay. The cytotoxic effects induced by taxanes toward PBPC as measured by clonogenic assay were correlated with those found for multidrug resistance (MDR)-positive cell lines (IDN5109 > IDN5111 > IDN5127 > docetaxel > paclitaxel). We established a therapeutic index (TI) between the antitumor activity in MDR-positive cells and the toxicity toward PBPC. Paclitaxel and IDN5109, as determined by TI, showed the best value in MDR-negative and MDR-positive cells, respectively. The ranking of the cytotoxic effects observed in PB CD34+ was not correlated with that obtained in clonogenic assay and in cancer cells (IDN5127 > IDN5109 > docetaxel > IDN5111). Remarkably, in DNA analysis docetaxel induced the maximal cell cycle blocking activity. Newly developed taxanes IDN5109 and IDN5111 are endowed of a profile of anticancer activity in MDR-bearing cells and toxicity toward hematopoietic progenitors better than that of docetaxel. However, mechanism(s) underlying toxicity toward hematopoietic progenitors could be, at least in part, different from that of docetaxel and likely dependent on the interaction with P-glycoprotein function in PB CD34+ cells.

Abstract
Using a model of human cervical cancer (ME-180 cells), the anti-tumour activity of paclitaxel was compared to that of docetaxel and IDN5109, a newly developed taxane. The growth inhibition effect of taxanes was assessed after 3 days of exposure. DNA analysis, the taxane-dependent modulation of the expression of the alpha and beta subunits of tubulin and DNA fragmentation were assessed by flow cytometry. The presence of apoptosis was confirmed by morphological analysis using a laser scan cytometer. For the evaluation of "in vivo" anti-tumour activity, taxanes were administered to nude mice intravenously once daily, according to a q3/4d x 4 schedule. Docetaxel, IDN5109 and paclitaxel obtained "in vitro" IC(50) values of 0.86, 1.4 and 2.4 nM, respectively. DNA analysis demonstrated a transient block at the G(2)/M phase of the cell cycle only after 12 h of culture in the presence of taxanes and an increase of nuclear fragmentation suggestive for apoptosis after additional 12 and 60 h of exposure. Morphological analysis confirmed the presence of apoptosis. Taxanes induced a down-modulation of the alpha subunit of tubulin in the G(0/1) phase of the cell cycle, and an overexpression of the beta subunit in the G(2)/M phase. A strong anti-tumour activity was obtained "in vivo" for nude mice xenografted using ME-180 cells (T/C=0% for all drugs). These data indicate that the three taxanes are strongly active both "in vitro" and "in vivo" toward ME-180 cells. Clinical studies are now needed to ascertain if the higher anti-tumour activity observed "in vitro" using docetaxel and IDN5109 yields a better clinical response in advanced cervical carcinoma with respect to paclitaxel.

Abstract
Three new 7-0-substituted deacetamidothiocolchicine derivatives have been evaluated for their antitumor activity against various human tumor cell lines, some of which express the multidrug resistance (MDR) phenotype, for their impact on the cell cycle and their binding to tubulin. Colchicine and thiocolchicine were used as reference compounds. Thiocolchicine was the most active agent on MDR-negative cells in terms of growth inhibition, whereas for multidrug-resistant cells, thiocolchicone was the most active compound (IC50 = 14 nM). As indicated by statistical analysis, a perfect agreement for the potency order (IC50 values) of the compounds between all the MDR-negative cancer cells (k = 1.00), a poor agreement between MDR-positive and MDR-negative cancer lines, and a moderate agreement (k = 0.50) between the two resistant cancer cells MCF-7 ADRr and CEM VBL were observed. To gain further insight into the mechanism of the antitumor activity of colchicinoids, the most active compounds, colchicone and thiocolchicone, were selected to evaluate their effect on cell cycle, apoptosis, and tubulin interaction. The highest recruitment activity into the G21/M phase of the cell cycle was detected in thiocolchicone-treated breast cancer cells. Interestingly, after 72 h of culture, when the cell cycle block subsided, a consistent amount of DNA fragmentation, a hallmark of apoptosis, was evident. Morphological analysis of MCF-7 ADRr cells confirmed this hypothesis and revealed that thiocolchicone was able to induce apoptosis in this MDR-bearing model. We also demonstrated, using flow cytometry, that thiocolchicone interacts with alpha- and beta-tubulin, thereby affecting the expression of both subunits.

Abstract
This study was designed to assess the effects of administration of dietary soy on reproductive function and fertility of female Wistar rats. Four groups, each of 20 females, were used. Control animals were fed a standard cereal-based diet for rats. Treated animals were fed a standard diet supplemented with 0.7%, 1.2% or 2.4% of a soy extract. Treatment started at weaning and continued until day 7 post-partum (day of sacrifice). Growth depression was seen in the 2.4% soy group. Vaginal opening occurred earlier in females receiving soy supplemented feed when compared with controls. Analysis of vaginal smears revealed that all animals were cycling, although an increase in the mean duration of each cycle was seen in the 2.4% soy group. Uterine effects were observed in high-dose females and included increases in weight, oedema, endothelial hyperplasia and leucocytic infiltration. Vaginal modifications (i.e. inflammation, hyperkeratosis and dyskeratosis) and alterations in the distribution of follicular size in the ovaries were also observed among treated animals. These data suggest that long-term exposure to high doses of phytoestrogens can produce significant agonistic actions in several oestrogen-dependent tissues and parameters, even though in this model no clear influence on reproductive processes was observed.

Abstract
A cell population undergoing apoptosis usually contains varying proportions of cells in the diverse stages of the process, from very early continuously through to secondary necrosis. This heterogeneity acts as a confounding factor in metabolic studies if a general population is investigated. Using fluorescent probes and multiparameter flow cytometry, we report on metabolic changes occurring during X-ray-induced apoptosis in human peripheral blood lymphocytes and relate the observed alterations to cells at various phases of the process assessed by monitoring the progressive loss of selective plasma membrane permeability. Data show that alterations of mitochondria cardiolipin and a reduction of plasma membrane potential are rather early events as they commence in cells which still possess an impermeable plasma membrane. Conversely, mitochondrial transmembrane potential is impaired only when plasma membrane permeability starts to be altered, that is, in relatively later apoptotic cells, thereby reflecting the complexity of mitochondria demise during apoptosis. The prooxidant/antioxidant balance is altered in cells in early apoptosis with a correlated increase of prooxidants and depletion of thiols, the latter indicative for the progressive impairment of this detoxifying mechanism. The imbalance in prooxidant/antioxidant remained evident through apoptosis suggesting that oxidative damage starts early and then continues, eventually leading to cellular disruption. Assessing cell transit through the apoptotic process and coupling the observed metabolic changes to selected stages of the process enables one to improve the understanding of the temporary sequence of biochemical phenomena occurring in a given model.

Abstract
Recent data have demonstrated that the anti-oestrogen tamoxifen (TAM) is able to facilitate apoptosis in cancer cells not expressing oestrogen receptor (ER). In an attempt to identify the biochemical pathway for this phenomenon, we investigated the role of TAM as an oxidative stress agent. In two ER-negative human cancer cell lines, namely T-leukaemic Jurkat and ovarian A2780 cancer cells, we have demonstrated that TAM is able to generate oxidative stress, thereby causing thiol depletion and activation of the transcriptional factor NF-kappaB. As described for other oxidative agents, TAM was able to induce either cell proliferation or apoptosis depending on the dose. When used at the lowest dose tested (0.1 microM), a slight proliferative effect of TAM was noticed in terms of cell counts and DNA synthesis rate, whereas at higher doses (10 microM) a consistent occurrence of apoptosis was detected. Importantly, the induction of apoptosis by TAM is not linked to down-regulation or functional inactivation by phosphorylation of the antiapoptotic bcl-2 protein.

Abstract
A series of newly developed paclitaxel analogues have been tested for their growth inhibitory activity on two human breast cancer cell lines, one of which expresses the MDR (multidrug resistance) phenotype. Paclitaxel (taxol) was used as a reference compound. Three new classes of taxanes were analyzed: the cephalomannine compounds, the pyrazoline derivatives and the seco-derivatives. Our results demonstrated an increased antiproliferative activity of pyrazoline derivatives on drug-resistant cancer cells with respect to paclitaxel. These compounds were able to block MDR-bearing MCF-7 ADRr cells in the G2/M phase of cell cycle and, consequently, induce programmed cell death. In keeping with the antiproliferative effects, cells treated with paclitaxel derivatives showed a more pronounced cell cycle arrest than the parent compound paclitaxel. Also, apoptotic cell death, calculated as a percent of DNA fragmentation, occurred to a greater extent in cells exposed to pyrazoline derivatives. The development of new paclitaxel analogues with greater antitumour activity on MDR-positive cells may be useful in selecting new taxanes effective on resistant tumors.

Abstract
BACKGROUND To evaluate the efficacy and safety of intravaginal quaternary ammonium antimicrobial compounds (SQA) versus clindamycin 2% intravaginal cream (CL) in the treatment of bacterial vaginosis (VB). MATERIALS AND METHODS One hundred-thirty-three patients affected by VB were enrolled in the study from January 1995 to October 1997. Patients were classified according to Amsel's criteria and/or to the indications of the Scandinavian Society of Bacterial Vaginosis. Twenty-three patients were initially excluded from the study, and 110 patients were randomized in two groups, SQA versus CL. Patients were reevaluated after 3 weeks, 3 months and 6 months from the end of therapy. The safety of treatment was also investigated. RESULTS Of 110 patients, 59 were treated with SQA and 51 with CL. One hundred (90.9%) patients completed the therapy and were subjected to the first control after 3 weeks from the end of therapy. A significant reduction of most of the symptoms and all signs of VB was observed in the group treated with SQA. Similarly, a significant reduction of most of the symptoms (vaginal and urinary in particular) and all signs of VB was observed in the group treated with CL. The percentage of response was 86.7% for SQA group and 87.2% for CL group. Moreover, after 3 months from the end of therapy, 47.2% and 50% of the patients treated with SQA and CL, respectively, recurred, and after 6 months 78.5% and 75% of the patients recurred, respectively. CONCLUSIONS SQA treatment conferred 86.7% of response after 3 weeks from the end of therapy, with poor side effects and a good compliance in good keeping with the results obtained with CL treatment.

Abstract
We analyzed the prognostic significance of epidermal growth factor receptor (EGFR) in a large prospective series of 90 cervical cancer patients observed for a long follow-up period. EGFR levels ranged from 0 to 52.1 fmol/mg protein, with a median value of 6.0 fmol/mg protein. Patients with an advanced stage of disease expressed lower EGFR levels than those with an early stage of disease (median values were 7.8 fmol/mg protein for patients with stage I-II and 4.2 fmol/mg protein for patients with stage III-IV, P = 0.013). There was no correlation between EGFR expression and other clinicopathological parameters analyzed. No significant relationship was shown between EGFR positivity and overall survival. No significant relationship between EGFR status and disease-free survival was observed. Cox univariate regression analysis using EGFR as a continuous variable showed that EGFR levels are not associated with the risk of disease recurrence after treatment or death (P-value not significant). Our data didn't seem to indicate a prognostic role of EGFR in cervical cancer.

Abstract
In this study the in vitro antitumor activity of a series of 20 colchicine analogues was tested and compared with colchicine and thiocolchicine on three different human cancer cell lines, two of which express the multidrug-resistance (MDR) phenotype. At concentrations from 1 nM to 100 microM, all compounds tested inhibited cancer cell proliferation. The IC50 values indicate that the three fluorinated analogues were the most active compounds, with a similar decreasing order of potency (IDN 5005 > IDN 5079 > IDN 5080) on the two MDR-expressing cell lines, whereas thiocolchicine was the most effective compound on the MDR-negative MDA-MB 231 cells. A strong correlation (r = 0.94; P = 0.004) was found between IC50 values obtained using the two MDR-positive cell lines. Conversely, IC50 values obtained in MDA-MB 231 cells did not show a significant correlation with MDR-positive cell lines, thereby suggesting some difference in the antiproliferative mechanism(s) of colchicine analogues. Cell cycle analysis of the most active analogues in breast cancer cells showed a relationship between cell cycle blocking activity and growth inhibition. The most active agents on the MDR-positive MCF7 ADRr cell line, after 24 h of culture, in terms of cell cycle blocking activity were the three fluorinated analogues. Interestingly, after 72 h, when the cell cycle block subsided, a consistent amount of DNA fragmentation was evident. The extent of cell cycle block, measured as the G2/G1 ratio, was significantly correlated with the apoptosis rate expressed as a percentage of DNA fragmentation on both cell lines, thereby suggesting that a large number of blocked cells underwent the apoptotic pathway.
