Abstract
OBJECTIVE To investigate the relationship of umbilical vein flow (UVF) measured close to term with abnormal fetal growth and adverse perinatal outcome in a cohort of pregnancies at low risk of placental insufficiency. METHODS This was a prospective multicenter observational study conducted across two tertiary maternity units. Patients with a singleton appropriate-for-gestational-age fetus between 35 and 38 weeks' gestation were included. Pregnancies at higher risk of placental insufficiency or with fetal anomalies were excluded. At ultrasound examination, the abdominal circumference (AC), umbilical vein diameter and peak velocity of the umbilical vein were measured, and, using these variables, a new variable, UVF/AC, was calculated. The primary outcome was the occurrence of severely stunted fetal growth, defined as a greater than 40-percentile drop between estimated fetal weight at the third-trimester ultrasound and birth weight. The occurrence of adverse perinatal outcome (defined as one of the following: neonatal acidosis (umbilical artery pH < 7.15 and/or base excess > 12 mmol/L) at birth, 5-min Apgar score < 7, neonatal resuscitation or neonatal intensive care unit admission) was analyzed as a secondary outcome. RESULTS Between April 2021 and March 2023, 365 women were included in the study. The mean UVF/AC at enrolment was 6.4 ± 2.6 mL/min/cm, and 35 (9.6%) cases were affected by severely stunted fetal growth. Severely stunted fetal growth was associated with a lower mean UVF/AC (5.4 ± 2.6 vs 6.5 ± 2.6 mL/min/cm; P = 0.02) and a higher frequency of UVF/AC < 10th percentile (8/35 (22.9%) vs 28/330 (8.5%); P = 0.01). Moreover, UVF/AC showed an area under the receiver-operating-characteristics curve (AUC) of 0.65 (95% CI, 0.55-0.75; P = 0.004) in predicting the occurrence of severely stunted fetal growth, and the optimal cut-off value of UVF/AC for discriminating between normal and severely stunted fetal growth was 7.2 mL/min/cm. This value was associated with a sensitivity and specificity of 0.77 (95% CI, 0.60-0.90) and 0.33 (95% CI, 0.28-0.39), and positive and negative predictive values of 0.11 (95% CI, 0.07-0.15) and 0.93 (95% CI, 0.87-0.97), respectively. Regarding the occurrence of adverse perinatal outcome, this was associated independently with maternal age (adjusted odds ratio (aOR), 0.93 (95% CI, 0.87-0.99); P = 0.04), UVF/AC Z-score (aOR, 0.53 (95% CI, 0.30-0.87); P = 0.01) and augmentation of labor (aOR, 2.69 (95% CI, 1.28-5.69); P = 0.009). UVF/AC showed an AUC of 0.65 (95% CI, 0.56-0.73; P = 0.005) in predicting the occurrence of adverse perinatal outcome, and the optimal cut-off value of UVF/AC for discriminating between normal and adverse perinatal outcome was 6.7 mL/min/cm. This value was associated with a sensitivity and specificity of 0.70 (95% CI, 0.54-0.83) and 0.40 (95% CI, 0.34-0.45), and positive and negative predictive values of 0.14 (95% CI, 0.09-0.19) and 0.91 (95% CI, 0.85-0.95), respectively. CONCLUSIONS Our data demonstrate an association between reduced UVF close to term, severely stunted fetal growth and adverse perinatal outcome in a cohort of low-risk pregnant women, with a moderate ability to rule out and a poor ability to rule in either outcome. Further studies are needed to establish whether the assessment of UVF can improve the identification of fetuses at risk of subclinical placental insufficiency and adverse perinatal outcome. © 2023 The Authors.

Abstract
Smartphones in medical settings pose infection risks due to harbouring pathogenic bacteria. This pilot study assesses the effectiveness duration of sanitisation methods, focusing on 70% isopropyl alcohol wipes and UVC boxes, aiming to obtain preliminary data on the reduction in Total Bacterial Load 3 hours post-sanitisation. A randomised monocentric trial with two intervention arms (wipes and UVC boxes) was designed. As participants, healthcare workers from three wards at Fondazione Policlinico Universitario "A. Gemelli" IRCCS Hospital were recruited, stratified by ward, and block randomised within each ward to control confounders. Seventy-one healthcare workers, mostly nurses (62%) were included in the study. Initial bacterial load reduction was significant with both disinfection techniques, but after 3 hours both methods showed increased bacterial levels, with wipes displaying potentially higher residual efficacy (p=0.056). To adequately size a trial (89% power, significance level 0.05) for assessing the residual efficacy of alcohol-impregnated wipes compared to UVC boxes at 3 hours post-sanitisation, 503 professionals per group were required. This study highlights the necessity for guidelines on hospital smartphone sanitisation and educational initiatives for healthcare workers and patients. Further studies, adequately sized, are necessary to determine optimal sanitisation intervals and assess pathogen transmission risks.

Abstract
Introduction: Developing techniques for the tagless isolation of homogeneous cell populations in physiological-like conditions is of great interest in medical research. A particular case is Gravitational Field-Flow Fractionation (GrFFF), which can be run avoiding cell fixation, and that was already used to separate viable cells. Cell dimensions have a key role in this process. However, their dimensions under physiological-like conditions are not easily known since the most diffused measurement techniques are performed on fixed cells, and the fixation used to preserve tissues can alter the cell size. This work aims to obtain and compare cell size data under physiological-like conditions and in the presence of a fixative.Methods: We developed a new protocol that allows the analysis of blood cells in different conditions. Then, we applied it to obtain a dataset of human cord blood cell dimensions from 32 subjects, comparing two tubes with anticoagulants (EDTA and Citrate) and two tubes with different preservatives (CellRescue and CellSave). We analyzed a total of 2071 cells by using confocal microscopy via bio-imaging to assess dimensions (cellular and nuclear) and morphology.Results: Cell diameter measured does not differ when using the different anticoagulants, except for the increase reported for monocyte in the presence of citrate. Instead, cell dimensions differ when comparing anticoagulants and cell preservative tubes, with a few exceptions. Cells characterized by high cytoplasm content show a reduction in their size, while morphology appears always preserved. In a subgroup of cells, 3D reconstruction was performed. Cell and nucleus volumes were estimated using different methods (specific 3D tool or reconstruction from 2D projection).Discussion: We found that some cell types benefit from a complete 3D analysis because they contain non-spherical structures (mainly for cells characterized by poly-lobated nucleus). Overall, we showed the effect of the preservatives mixture on cell dimensions. Such an effect must be considered when dealing with problems highly dependent on cell size, such as GrFFF. Additionally, such information is crucial in computational models increasingly being employed to simulate biological events.

Abstract
BACKGROUND Spinal muscular atrophy (SMA) is due to the homozygous absence of SMN1 in around 97% of patients, independent of the severity (classically ranked into types I-III). The high genetic homogeneity, coupled with the excellent results of presymptomatic treatments of patients with each of the three disease-modifying therapies available, makes SMA one of the golden candidates to genetic newborn screening (NBS) (SMA-NBS). The implementation of SMA in NBS national programmes occurring in some countries is an arising new issue that the scientific community has to address. We report here the results of the first Italian SMA-NBS project and provide some proposals for updating the current molecular diagnostic scenario. METHODS The screening test was performed by an in-house-developed qPCR assay, amplifying SMN1 and SMN2. Molecular prognosis was assessed on fresh blood samples. RESULTS We found 15 patients/90885 newborns (incidence 1:6059) having the following SMN2 genotypes: 1 (one patient), 2 (eight patients), 2+c.859G>C variant (one patient), 3 (three patients), 4 (one patient) or 6 copies (one patient). Six patients (40%) showed signs suggestive of SMA at birth. We also discuss some unusual cases we found. CONCLUSION The molecular diagnosis of SMA needs to adapt to the new era of the disease with specific guidelines and standard operating procedures. In detail, SMA diagnosis should be felt as a true medical urgency due to therapeutic implications; SMN2 copy assessment needs to be standardised; commercially available tests need to be improved for higher SMN2 copies determination; and the SMN2 splicing-modifier variants should be routinely tested in SMA-NBS.

Abstract
Introduction Up to 80% of patients scheduled for surgery experience preoperative anxiety, which may implicate perioperative psychological and physical discomforts. Several studies focused on this phenomenon in neurosurgical setting, still controversial evidence exists. Objectives Our aim is to synthesize this evidence, investigating prevalence, implications and therapy of preoperative anxiety in brain surgery patients. Methods We performed a systematic review of literature by searching PubMed, Embase, and Cochrane Library databases. Data were extracted using the PICO framework. PRISMA guidelines were applied, and the risk of bias was assessed using the RoB 2 and ROBINS tools, as was the methodological quality of the included studies, following GRADE criteria; we excluded articles with serious risk of bias and/or low quality. Results We included 27 articles, accounting for 2558 patients of twelve different countries. Prevalence of anxiety before brain surgery was up to 89%, reaching higher levels in women. Anxiety concerned mostly anesthesia and surgical outcome. No correlation emerged between level of anxiety and laterality, histological type of tumor or survival rate. Before surgery, anxious patients performed worse in cognitive tasks and had worse subjective evaluation of their cognitive abilities. After surgery, preoperative anxiety was associated with depression, longer hospitalization, increase of physical disability and lower quality of life. Effective approaches to reduce anxiety were acupuncture, music therapy, virtual reality and pharmacological support. Conclusions Preoperative anxiety in brain surgery patients is a common experience that should not be underestimated to achieve a better perioperative care through early detection and adequate pharmacological or non-pharmacological management.

Abstract
Preoperative anxiety is a common reaction exhibited by up to 80% of patients who are scheduled for surgical procedures and characterized by psychological and physical changes which may affect their perioperative period. Our aim is to report the most up-to-date evidence on preoperative anxiety in brain surgery patients through a systematic analysis of the studies produced in the last decades. We performed a systematic review of literature by searching PubMed, Embase, and Cochrane Library databases. Data were extracted using the Population, Intervention, Comparison, Outcome framework and critically analyzed. PRISMA guidelines were applied, and the risk of bias of the included studies was assessed using the Risk of bias (RoB) 2 and ROBINS tools, as was the methodological quality, following GRADE criteria. We included 27 articles, accounting for 2558 patients in twelve different countries. The prevalence of preoperative anxiety ranged from 17 up to 89%, higher in female patients. Preoperative anxiety was associated with lower quality of life and cognitive performance, higher need for information, poorer memory and attention, longer hospitalization, depressive symptoms, and increase of physical disability; no correlation with survival rate was found. Seven randomized controlled trials attested the efficacy of acupuncture, music therapy, virtual reality, and pharmacological support in lowering anxiety levels. Preoperative anxiety is a common phenomenon that could negatively affect the perioperative period of brain surgery patients: this is something that should not be neglected to achieve better care through early prevention and optimal management.

Abstract
Objectives The computerized tomography with perfusion technique (pCT) has proved to have some potentialities in the oncologic field as a possible tool to identify neoangiogenesis in vivo. The purpose of the present job is to test the correlations existing between perfusion data and pathologic features in the evaluation of vascularization in kidney cancer. Methods 6 patients with clinical diagnosis of renal tumor awaiting surgical treatment underwent preoperatively pCT scans. Axial images encompassing the greatest diameter of the cancer were compared with the respective histological sections. Results A correlation between tumor histological subtype and perfusion index was observed and shown. Moreover, clear cell RCC of different Fuhrman grades showed statistically significant differences in perfusion values (T test). Specifically, high perfusion indexes were associated with high density of microvessels with abnormal architecture at the microscopic evaluation of tumor specimen. Conversely, lower perfusion index were detected in tumors with lower microvascular density. Conclusions pCT scans can provide significant data on tumor angiogenesis and, eventually, suggest tumor histological subtype. The possibility of identifying preoperatively tumor histotype can be of particular relevance in patients with small renal tumors, suitable for minimally-invasive surgery or active surveillance program.

Abstract
Endocannabinoids are a class of lipid mediators involved in a wide range of physiological pathways including pain perception, and immunological defences. In particular, the involvement of endocannabinoids in bone metabolism and bone resorption has recently been studied. Moreover, one study on total knee arthroplasty describes the probable role of endocannabinoids in pain perception after surgery. The aim of the present study was to evaluate variations of endocannabinoid concentrations in patients undergoing total hip or total knee arthroplasty before and after surgery. Sera from 23 patients were collected at three different times: before surgery and at two different times during rehabilitation, and endocannabinoids were quantified by HPLC-MS/MS analysis. Mean values of endocannabinoids in presurgical serum samples were: 6.11±0.5 ng/ml for N-palmitoylethanolamide, 1.39±0.08ng/ml for N-stearoylethanolamide, 4.84±0.04 ng/ml for N-oleoylethanolamide, 0.44±0.03ng/ml for N-arachidonoylethanolamide, 0.84±0.05ng/ml for N-linoleoylethanolamide, 0.17±0.01ng/ml for N-α-linolenoylethanolamide. Statistical analysis showed a significant decrease of all the endocannabinoids after surgery, while there were no remarkable differences between total hip and total knee arthroplasties or between genders. Moreover, the results show no significant correlation between endocannabinoid concentrations and C-reactive protein and Erythrocyte sedimentation rate. The present study shows for the first time a specific and univocal behaviour of six endocannabinoids and N-acylethanolamides in orthopaedic surgery, suggesting the endocannabinoid system as a possible pharmacological target for presurgical therapeutics.

Abstract
The onset of an infectious complication in an infant leads to an increase in costs for the health of the newborn, psychological costs for the family, and economic costs for the hospital. Several studies have demonstrated that hospital infections are preventable in part: the adoption of "safe" care practices in fact involves the reduction of 35%. Essential principals for the prevention of nosocomial infections are: a particular attention to the care of the skin, of the umbilical stump and of the newborn's eyes, as well as of the tools for every-day use; the implementation of correct behaviors during washing of the hands; prevention of the spread of respiratory viruses; the environmental control; training courses for healthcare personnel and for infant's families.

Abstract
PURPOSE Granulocyte colony-stimulating factors (G-CSFs), filgrastim and lenograstim, are recognised to be useful in accelerating engraftment after autologous stem cell transplantation. Several forms of biosimilar non-glycosylated G-CSF have been approved by the European Medicines Agency, with limited published data supporting the clinical equivalence in peripheral blood stem cell mobilisation and recovery after autologous stem cell transplantation. METHOD With the aim of comparing cost-effective strategies in the use of G-CSF after autologous stem cell transplantation, we retrospectively evaluated 32 patients consecutively treated with biosimilar filgrastim XM02 (Tevagrastim) and 26 with lenograstim. All patients received G-CSF (biosimilar or lenograstim) at a dosage of 5 mcg/kg/day subcutaneously from day 5 to absolute neutrophil count of 1500/mmc for three days. RESULTS The median time to absolute neutrophil count engraftment was 11 days for the filgrastim XM02 group and 12 days for the lenograstim group. As for platelets recovery, the median time was 12 days in both groups. The median number of G-CSF vials used for patients was 9.5 for Tevagrastim and 10.5 for lenograstim, reflecting a mean estimated cost of about 556.1 euros for Tevagrastim versus 932.2 euros for lenograstim (p< 0.001). The median days of febrile neutropenia were 1.5 and 1 for filgrastim XM02 and lenograstim, respectively. No adverse event related to the use of XM02 filgrastim was recorded. CONCLUSION In our experience, filgrastim XM02 and lenograstim showed comparable efficacy in shortening the period of neutropenia after cytoreduction and autologous stem cell transplantation, with a favourable cost effect for filgrastim XM02.

Abstract
Radical prostatectomy (RP) represents the most frequently chosen therapeutic option for treating newly diagnosed localized prostate cancer. Cancer recurrence after surgery is linked to biologic variables. But are these the only ones that must be considered to give an explanation of a possible local or distal recurrence, or can it also admit the possibility that an incorrectly conducted surgery has a negative role in the unfavorable evolution after PR? Prostate cancer recurrence, as a matter of fact, is related also to surgical technique. The PR, by definition is a surgical, potentially complicated act. Surgery outcomes depend on a whole serires of factors: the surgeon's ability, and the way the surgical procedure is conducted, play an essential role. Here we evaluate the role of biological and surgical factors on biochemical recurrence.

Abstract
This study explores the possibility that the celiac disease (CD) may be correlated with the insurgence of some oral signs, as based on a systematic review of the literature. Should this correlation be proven, any dentistry's screening would then be important to diagnose early celiac sprue pathogenesis. A literature survey was accomplished by using the Medline database (Entrez PubMed). The survey, which covered the period from the year 1972 to 2009, provided 382 published articles. Of these, 29 articles were selected according to inclusionary/exclusionary criteria, and consequently qualified for the final review analysis. Manual searching through the reference lists of the selected articles allowed the obtainment of others 17 articles. Findings gathered through this literature's review corroborate the significance of a causal relationship between some oral signs and CD. There are enough evidence making the correlation between CD and oral defects scientifically sustainable. This recognition should lead dentists to play more significant roles in screening for CD, as otherwise, if not properly diagnosed and not treated with a gluten-free diet, may eventually cause some malignancies.

Abstract
From January 2004, R/R MM cases referred to the Institution received LD-VTD regimen. Patients, irrespective of age, PS and life expectancy, were enrolled in the study once they had a measurable disease. Planned therapy: Velcade 1.0 mg m(-2) i.v. twice weekly for 2 weeks of a 28-day cycle for up to 6 cycles, oral Dexamethasone 24 mg on the day of and the day following each Velcade dose and Thalidomide 100 mg each evening. DVT prophylaxis with warfarin to maintain international normalized ratio between 2.0-3.0 was planned in all patients. As of 1 June 2005, 18 were the treated patients: median age 63 years, median time from diagnosis 5.8 years, a median of 4 previous therapy lines. Seventeen were the valuable patients and 9 (53%) were the responders: 2 CR, 6 PR, 1 MR. Six were the stable disease and 2 the progressive ones. Median time to best response was 2 months. Toxicity was negligible. No case of DVT was recorded. Except for the first cycle, subsequent cycles were delivered on an outpatient basis. After a median follow-up of 11 months, 12 patients were alive and 5 died (3 disease progression, 1 heart failure, 1 intestinal bleeding). Thus, the LD-VTD regimen applied appears feasible and effective in elderly and heavily pre-treated R/R myeloma patients.

Abstract
OBJECTIVES. Several authors hypothesized the usefulness of the non-contrast helical computed tomography (NCHCT) with the determination of stone Hounsfield Unit (HU) values in order to predict urinary stone compositions. Preoperative knowledge of stone composition might be interesting in pre-operative decision-making process. The aim of this study was to evaluate the possible correlation between stone chemical composition and correspondent stone HU value in an in-vivo experience. METHODS. Forty patients with urinary stones were preoperatively studied with abdominal NCHCT, where stone HU values were reported. Stone chemical composition was obtained in each patient, using the colorimetric method. The HU value of each stone was compared with the correspondent chemical analysis. Results. The median HU values of calcium oxalate (n=10), mixed calcium oxalate and phosphate (n=19), calcium phosphate (n=2), uric acid (n=6) and mixed uric acid and calcium oxalate (n=3) stones were 1060 HU [interquartile range (IQR) 743.75-1222.5]; 900 HU (IQR 588.5-1108.5); 774 HU (range 720-828); 371 HU (IQR 361.25-436.25) and 532 HU (range 476-626), respectively. CONCLUSIONS. Our results confirmed a statistically significant difference of the HU values between calcium and pure uric acid calculi, suggesting a correlation between stone chemical composition and CT-density.

Abstract
BACKGROUND. The management of bilateral renal stones still represents a therapeutic challenge and synchronous bilateral percutaneous nephrolithotomy (PCNL) appears to be a well tolerated, safe and relatively rapid procedure with a favorable cost-benefit ratio. The purpose of the present study is to report our experience in the synchronous percutaneous treatment of bilateral renal stones. METHODS. We retrospectively evaluated clinical files from 4 consecutive patients (BS, BE, OCB, FL), who underwent a synchronous bilateral PCNL, performed by the same operator (ZF), for the management of renal persistent and/or recurrent stones after extracorporeal shock wave lithotripsy, or other surgical maneuvers. From each patient's file we recorded a clinical history, any peri- and post-operative complication, any therapeutic resolution employed and the outcomes in terms of stones persistence/recurrence. RESULTS. Overall, 3 men (BS, BE, FL) and 1 woman (OCB), their age ranging from 31 up to 76 years, consecutively underwent synchronous bilateral PCNL. In 75% of cases a calcium- oxalate nephrolithiasis was found. We did not find any peri- or post-operative complication. All patients were stone-free after a mean follow-up of 12 months (range: 3-24 months). CONCLUSIONS. Synchronous bilateral PCNL is a relatively safe procedure; it may be performed in selected patients without increasing the morbidity of this surgical maneuver. The simultaneous treatment of the contra-lateral kidney may be taken into account only when the PCNL of the first side has been performed quickly and easily without any peri-operative complication.

Abstract
Since 1996, the Emilia-Romagna Region has been promoting screening programmes for cervical cancer, selecting resident women aged 25-64 as a target population. This analysis concerns a second round of screening performed in the city of Ferrara and its province. A total of 103,971 women were invited to be screened, but only 55.51% of them arrived on the day of the scheduled screening. We therefore decided to investigate the reasons for this lack of participation using preliminary findings from the local screening program registry. These indicated that non-attendance was related to variables such as area of residence and age, and significant differences were observed between localities, with a consistently greater participation in industrial neighbourhoods and their surroundings than in rural areas. In order to elucidate these observations further, a cross-sectional survey, placing special emphasis on setting, area of residence, age and level of education, was performed by structured telephone questionnaire, in order to identify the reasons behind non-attendance. Approximately 94% of the contacted women agreed to be interviewed, thereby demonstrating that a telephone interview is a valid means of collecting data in such cases. It should be noted that, among the women unwilling to respond to the questionnaire, a marked increase in percentage was observed for those resident in rural areas, of whom approximately 50% fell into the under-40 age group. The results of the survey indicated, as demonstrated by several previous studies, that age and the area of residence are both determining factors in the decision or not to participate in a screening programme. It was also observed that women who had completed the lower and upper secondary school education were shown to pay greater attention to health matters than those who had not.

Abstract
The paper presents the early results of a study involving a group of 312 non smoking and not professionally exposed subjects (144 males and 168 females) in order to evaluate the probable presence of urinary mutagens possibly derived from aspecific exposures. Urine samples were assayed by the Ames test on the YG1024 Salmonella typhimurium strain in the presence of S9 mix with plate incorporation method with preincubation. At the moment of sample collection, the subjects were invited to fill a questionnaire on their main characteristics and lifestyle. On the basis of laboratory data analysis, it emerged that, on 288 samples with a valuable mutagenic activity, 20 urinary extracts (8 of which were males and 12 were females) showed mutagenicity levels twice as much as spontaneous revertants. Diet and indoor exposure to passive smoking, fireplace and cooking fume exposure seemed to play a major role among the lifestyle behaviours investigated in generating positive mutagenic response with a statistically significant difference between positive and negative samples induction (Chi square, P = 0.0057 and P = 0.0168 respectively). After correction of induced revertants by means of creatinine excretion determination, it appeared that females, who had the higher mean urinary mutagenic activity, showed a mutagenicity level twice as much as men (364 +/- 491 revertants/mmole creatinine for males against 605 +/- 868 revertants/mmole creatinine in females, Mann-Whitney U-test, z = -3.97, P < 0.0001) possibly in consequence of their greater cooking fumes exposure. The study, that carefully evaluated the characteristics of involved subjects, reveals the presence, even though modest, of mutagens in urine of an apparently not significantly exposed population. In addition, standardization of method leads to suppose little feasible a confounding influence of considered features. Moreover, it would be therefore rather interesting to study the effect of low exposure time persistence.

Abstract
7093 Background: Byrd et al (Blood 2003) confirmed the synergistic effect of Rituximab and Fludarabine in the treatment of CLL patients (pts). The choice of purine analogue still remains controversial. We evaluated feasibility, efficacy, and toxicity of 2-CdA-Rituximab combination in the treatment of CLL and SLL pts requiring treatment. Methods: The combination therapy consisted of intravenous Rituximab at a dose of 375 mg/m2 on Day 1 and 2-CdA at a dose of 0.1 mg/kg (sc injection) per day on Days 2 through 6. The course was repeated at 4-week intervals for 4 times. 31 pts (21 CLL and 10 SLL) was enrolled in the study and the median age was 59 years (31–73); 42% of pts were pre-treated. A CT scan was abnormal in 95% of CLL pts. Immunophenotypic evaluation by ZAP-70 was positive in 70% of pts while no evaluable pts showed an adverse prognostic cytogenetic features by FISH. Minimal residual disease (MRD) assessment was performed by flow-cytometry and PCR methods. Results: 2 pts had to discontinue therapy after 2 cycle: one due to herpes zoster reactivation and the other one to the progression disease (PD). We observed grade 3 and 4 neutropenia in 4 pts (12%), major infections in 4 pts (12%) and no episodes of grade 3–4 thrombocytopenia. 24 pts were evaluable for response with an ORR of 96%. At the end of therapy 10 pts (42%), 7 CLL and 3 SLL, achieved a CR, with negative MRD (by PCR) in 4 pts (3 untreated); 13 pts (54%) obtained a PR and 1 patient had no response. With a median follow-up of 12 months (range 3–34) 7 pts (2 pts with MRD+CR and 5 pts with PR after treatment) experimented a PD; 5 of these pts were pre-treated and 2 died because of PD. Conclusions: The combination of 2- CDA and Rituximab seems to be tolerable and active principally for untreated pts and able to induce a molecular clearance also in pre-treated pts. The achieving of a CR with negative MRD seems to be the most important issue to improve the outcome. No significant financial relationships to disclose.

Abstract
The incidence and prognostic relevance of bone marrow (BM) and leukapheresis (PBPC) tumor cell contamination (TCC) in breast cancer patients is still to be circumstantiated. We developed a new comprehensive gene expression panel to study cytokeratins (CK), maspin (MAS) and mammaglobin (MAM) as possible predictors of prognosis. Forty-eight patients undergoing high dose chemotherapy (HDCT) and PBPC support were enrolled and analyzed for TCC on 116 PBPC apheresis and 96 BM obtained at basal conditions. All of the patients were evaluated by reverse transcriptase nested PCR (RT-PCR) for MAM and MAS gene expression and by immunocytochemistry (ICC) and nested RT-PCR to evaluate CK expression. PBPC and BM frequency of CK-positive (+) cells was 12-13% by ICC and 71-73% by RT-PCR respectively. Sixty-seven percent of CK ICC+ samples were MAM RT-PCR+ and 89% of them were MAS RT-PCR+. PBPC and BM frequency of MAM+ cells was 21% and 31% respectively, while for MAS+ cells it was 48% and 52% respectively by RT-PCR. After 71 mo median FU, 16 patients (33%) relapsed and 14 (88%) had BM/PBPC TCC. No marker had an impact on overall survival (OS) but MAS expression on BM and MAM expression on PBPC correlated with a statistically significant improved (p=0.05) and worsened RFS (p=0.06) respectively. These data confirm the activity of MAM as a negative prognostic factor and show for the first time that MAS could work as a tumor suppressor gene even in a clinical setting, since it protects from recurrence.

Abstract
Despite progress in AML therapy, most patients eventually relapse, even the ones with normal or favorable karyotype. Since survival is poor once relapse occurs, new genetic tools above karyotype at diagnosis are needed to predict leukemia free survival. Recently, Flt3/ITD has been reported as an independent marker for clinical outcome in most studies concerning adult AML patients. To assess the prognostic relevance of activating mutations of Flt3, pretreatment samples of 100 not-M3 AML patients, all of them subjected to an intensive chemotherapy regimen, were analyzed for Flt3/ITD; 25/100 patients had one or more Flt3-ITD. Flt3/ITD patients had higher WBC count (P = 0.005), a lower incidence of a preceding MDS (P = 0.004) and most of them had a normal karyotype. Flt3/ITD had no impact on CR achievement while karyotype remained the most powerful prognostic factor (HR 2.8 95% CI 1.2 6.3). However, post-remission outcome was significantly worsened by the presence of Flt3/ITD. Median RFS of the Flt3/ITD patients was 5 vs. 27 months compared to the patients with wild-type Flt3 (P = 0.0002); moreover, Flt3/ITD patients had a significantly poorer post-remission survival (11 vs. 38 months, P = 0.01). On multivariate analysis, the presence of Flt3-ITD significantly affected relapse free survival and post-remission survival (HR 3.1 and 2.1, respectively). Thus, post-remission outcome highly depends on Flt3 status. Flt3 mutations identify patients at high risk of relapse, who should prospectively receive, according to age, either more aggressive or alternative therapeutic approaches.

Abstract
When studying unidentified putrefied or skeletonised human remains it may be difficult to obtain information on drug habits which may prove important for the construction of a biological profile or lead to hypotheses on the manner of death. The detection of morphine and codeine in teeth from human remains may prove crucial in obtaining such information and thus give forensic odontology and anthropology a further tool for identification. Because teeth can be an important deposit of exogenous substances accumulated both in the pulp and in the calcified tissues, they are an invaluable source of data from a toxicological point of view. The authors therefore tested 3 groups of teeth for morphine and codeine: the first group consisted of artificially aged teeth from individuals known to have died of heroin overdose; the second, of teeth from individuals with no history of drug abuse; the third, of teeth from cases of burnt, putrefied and skeletonised remains found in conditions strongly suggestive of a drug-related death. Results showed that in groups 1 and 3 morphine and codeine could still be identified in the teeth, proving that these tissues may be a reliable source for toxicological information concerning the history of the individual. Further studies are needed to verify whether the substances detected reflect drugs in circulation in an acute phase (and therefore present in blood vessels in the pulp) or whether they represent drugs which have percolated and been stored in dentine and enamel and thus denote a history of drug abuse. Nonetheless this study shows that teeth may be an important source of toxicological information in the forensic scenario.

Abstract
INTRODUCTION In Spiral CT, the pitch is the ratio of the distance the tabletop travels per 360 degrees rotation to nominal slice width, expressed in mm. Performing Spiral CT examinations with pitch 2 allows to reduce examination time, exposure and contrast dose, and X-ray tube overload. We investigated the yield of pitch 2 in lung parenchyma studies, particularly relative to diagnostic image quality. MATERIAL AND METHODS Thirty patients were submitted to Spiral CT with pitch 1 [10 mm slice thickness, 10 mm/s table feed; 10 mm (a') and 5 mm (a") reconstruction index: protocol A] and with pitch 2 [10 mm slice thickness, 20 mm/s table feed; 10 mm (b') and 5 mm (b") reconstruction index: protocol B]. Five expert radiologists evaluated the images separately and blindly, grading noise, bronchial wall resolution and diagnostic yield on a 0-5 point scale. The results of protocol A versus protocol B images were analyzed statistically using the Mann-Whitney U-test. RESULTS The mean scores for each parameter ranged 4.13 (.70 standard deviation) for protocol B with 5 mm reconstruction index (b") to 4.81 (.44 standard deviation) for protocol A with 10 mm reconstruction index (a'). These values (max: 5) indicate very positive results on both protocol A and B images. There were no statistically significant interprotocol differences, except for bronchial wall resolution, in favor of protocol A with 5 mm reconstruction index (a") (p = .025), and for diagnostic yield, in favor of protocol A with 10 mm reconstruction index (a') (p = .018). CONCLUSIONS Spiral CT with pitch 2 is a reliable tool for lung parenchyma studies which permits to reduce examination time and contrast dose, as well as X-ray tube overload and exposure dose.

Abstract
This study was aimed at comparing the diagnostic value of conventional computed tomography (CCT) with that of spiral computed tomography (SCT) in sinonasal structures and ostiomeatal complex in thirty patients with inflammatory disease. Ten patients were examined with CCT (3-mm slice thickness, 120 kV, 100 mA, 2-s gantry rotation) and 20 were examined with SCT (3-mm slice thickness, 120 kV, 200 mA, 1-s gantry rotation and computed image reconstruction every 3 mm); table gain was 3 mm (Pitch 1) in 10 patients and 5 mm (Pitch 1.6) in the other 10 patients. With the latter study protocol, diagnostic image quality was the same as with the other two protocols. Moreover, examination time was reduced, with increased patients' comfort; the exposure dose and X-ray tube overload were also reduced, with increased system yield.

Abstract
Eleven patients surgically treated for fracture of the acetabulum were examined postoperatively by MRI in order to reveal any signs of necrosis of the femoral head at an early stage. The means of osteosynthesis used underwent preliminary testing in order to exclude magnetic or thermal phenomena. The study confirmed the usefulness of this test in the early diagnosis of this serious complication. In 3 cases the presence of the means of osteosynthesis obstructed a correct interpretation of the images.

Abstract
In nine samples of adult populations (2707 males and 2871 females, aged 20-59 years) we studied the relationship between educational level and several lifestyle factors at risk for coronary heart disease (CHD), (i.e., smoking, alcohol consumption, dietary fat intake, sedentary behaviour at work and leisure) and the association between education and certain CHD risk factors (i.e., total cholesterol, HDL-cholesterol, triglycerides, systolic and diastolic blood pressure, body mass index). The data were analyzed separately in samples from North, Central and Southern Italy. The results show that educational level is often associated to the lifestyle factors considered here. This association was positive for both men and women for physical activity at leisure and work stress and only for women with respect to smoking. It was negative for both men and women for alcohol consumption and physical activity at work and for men only for cigarette smoking. The age-adjusted mean levels of the CHD risk factors show some significant differences among subjects with different educational levels, which were not always the same for the three geographical areas. This was with the exception of BMI in females, which appears negatively associated to education in all areas. These differences decreased after adjustments were made for daily cigarette smoking, wine consumption and dietary fat intake. Education seems to play a determining role in lifestyle, however, its direct and indirect effects on some major CHD risk factors are somewhat different in areas at different socio-economic conditions.

Abstract
Forty-eight patients with oncologic prosthetic devices (modular rotatory shoulder, Kotz, custom made) and metallic means of fixation (Sherman's plates, Ender's rods, etc.) underwent MRI in order to: 1) assess possible physical changes in the magnetic field or the alloys under examination; 2) detect the presence and type of artifacts, and 3) verify the onset of eventual noxious effects of the alloy on the patient. The diagnostic investigation was preceded by an experimental phase which was characterized by: A) a study of the temperature fluctuations of the alloys when submitted to the magnetic field and to radiofrequency; B) the identification and characterization of the artifacts, as well as C) their physical interpretation. During examination, there was no evidence of any mobilization of the means of fixation, sensation of endogenous heat, or other subjective complaints on the part of the patient. The authors observed that, even in the presence of artifacts, MRI provided good evaluation of the soft tissues around the devices by identifying tumor recurrences in the presence of an oncological prosthesis. MRI was also capable of showing trophic changes in the tissues surrounding the means of fixation. Thus, the method exhibits no contraindications in the study of these patients but, on the other hand, does not allow the evaluation of the integrity or mobilization of the prosthetic devices.

Abstract
Eleven patients suffering from neuroblastoma and Wilms' tumor were examined with MR imaging (25 examinations). The results were compared with those obtained with other diagnostic methods--e.g. CT--to verify MR reliability in locating and staging the lesions. Signal patterns were studied, as recorded on T1- and T2-weighted sequences using various repetition and echo times. An attempt was made to verify the presence of pathognomonic findings and to differentiate tumors from post-therapy fibroses. All findings were subsequently confirmed at biopsy or, in the patients who underwent surgery, by surgical findings. To carry out all the procedures, the patients had to be sedated or to be administered a general anesthetic. When possible, a brain or surface coil was used to obtain a clear, well-defined image in thin-section (7-8 mm) sequences. MR imaging allowed all lesions to be detected and located in the examined population. A large thrombus in the vena cava and local adenopathy were observed in a patients suffering from Wilms' tumor. Spread into the spinal canal was present in 2 cases of neuroblastoma. One of the main advantages of MR imaging is its multiplanarity which usually allows lesion extent to be demonstrated, together with the involved organs. The additional advantages of MR imaging over CT should not be underestimated. MR allows images of the abdomen to be obtained devoid of respiratory artifacts and provides a sharp contrast between pathological and healthy tissue without contrast medium administration. In all the patients who underwent it, MR imaging proved superior to CT in the evaluation of the intraspinal spread of paraspinal lesions. MR also allowed serial follow-up to be carried out, with no risk of subsequent proteximetric problems, thus helping distinguish tumor masses from fibrous tissue in all patients.

Abstract
Forty-four patients affected with thoracic esophageal carcinoma underwent preoperative CT to evaluate the value of this method in both staging and assessing the resectability of esophageal tumors. The authors compared the CT findings with intraoperative macroscopic ones, pathologic, and bronchoscopic results in mid-high neoplasms. CT staging criteria were drawn from a careful review of literature and from personal experience. Thirty-nine patients were submitted to surgery, and esophagectomy was possible in 34 of them. CT diagnostic accuracy was higher in proximal esophageal tumors than in sub-bronchial ones; as for the surgical choice, CT provided fundamental guidelines, especially if the choice was a blunt esophagectomy where it is important to exclude tumoral involvement of the airways (accuracy: 82.6%) or of the aorta (accuracy: 89.7%). CT staging accuracy was limited by the low sensitivity of the method in detecting lymphatic (local: 66.6%, distant: 64.2%) and hepatic metastases. Combined thoraco-abdominal CT, tracheobronchoscopy and liver US, besides MR imaging and endoscopic US, allow a better preoperative evaluation of esophageal carcinomas.

Abstract
From December 1987 to January 1989, 66 patients were studied by liver MR imaging: 38 of them were found to have liver tumors, and 28 were studied as a control group. The authors' purpose was to compare the diagnostic accuracy of 0.5 T MR imaging to that of other techniques (CT and US), using mixed Spin-Echo and Inversion Recovery sequences (UTSS). Spin-Echo sequences were used first, with very short repetition times (TR 260, TE 20). Mixed sequences (UTSS) followed, both T1-weighted, lasting 12' and 13' respectively, and then T2-weighted Multiecho sequences lasting 9'. T1-weighted Inversion Recovery sequences provided with good contrast between normal and neoplastic parenchyma, and demonstrated all the lesions shown by other techniques. UTSS proved to be the most sensitive sequence in exactly defining the lesion and its relationship to hepatic vessels. Signal characteristics of T2-weighted Multiecho sequences allowed some neoplastic types to be distinguished that were found to have a particular behavior, especially hemangiomas. T1 and T2 maps were used to characterize the different lesions.

Abstract
Twenty-five patients (16 with malignant soft-tissue tumors and 9 with suspected recurrence), previously studied with conventional radiography and Computed Tomography (CT), were examined with Magnetic Resonance (MR) imaging. MR findings were surgically and anatomo-histopathologically confirmed. Six more patients with benign lesions were examined for differential diagnosis. MR capabilities are here evaluated to detect and eventually characterize the lesion, and to assess its exact location. No false positives were found, and there was only one false negative, in a case of recurrent Malignant Fibrous Histiocytoma (MFH). In another case of MFH the infiltration of the adjacent vessels and nerves was not imaged. After a careful review of all the examinations, MR imaging appears to be able to provide much information for surgical planning about tumor extent and margins, thanks to its contrast resolution between tumor and surrounding anatomical structures. Therefore, MR imaging can be reasonably employed as the examination of choice when a soft-tissue tumor is clinically suspected, because of the multi-planar images it provides with and of its differential imaging parameters.

Abstract
A new pulse sequence characterized by simultaneous multislice spin echo (SE) and short inversion time (TI) with inversion recovery (STIR) acquisitions is demonstrated. For the STIR component, a repetition time of 1,000 ms and TI of 210 ms were chosen to suppress the signal from normal liver at 0.5 T and create a fast sequence suitable for screening purposes. Phase correction of the STIR with the SE's signal as a reference resulted in high contrast real IR images that were free of phase error artifact. In 13 min the entire liver could be imaged in 14 adjacent slices, each slice portrayed in an ensemble of four images: a T1-weighted SE image, IR real and modulus images, and a T1 map. Forty-one patients with liver pathology and 10 normal volunteers were examined with the sequence implemented on a commercially available 0.5 T imager (Gyroscan; Phillips). Images demonstrated high liver-lesion contrast and sensitivity to liver lesions. Lesions of less than 1 cm in diameter and lymphomatous lesions, commonly occult to magnetic resonance, were detected.

Abstract
Correct orthopedic therapy for traumas of the cervical rachis requires perfect knowledge of the spatial balance of the fracture focus. The authors believe Computed Tomography (CT) to be the most suitable, and often indispensable, method for this purpose. Twenty-four patients were examined for traumatic pathology of the cervical rachis. In 7 cases with clinically minor traumas, the negative outcome of the traditional exam was considered reliable and sufficient for therapeutic purposes. The extant 17 patients were examined also by means of CT, either to better determine the characteristics of skeletal lesions already ascertained with traditional techniques or to assess the presence of clinically-suspected osteo-articular lesions, even with negative conventional X-rays. For 9 of these patients orthopedic treatment was considered sufficient, whereas 8 patients underwent surgery and were subsequently examined with CT, which allowed correct evaluation of postoperative pictures even in the presence of metal prostheses. In 10 cases CT demonstrated the presence of lesions which had not been diagnosed with traditional X-ray techniques.

Abstract
Thirty-five patients with temporal bone fractures were examined; the fractures were sometimes associated with dislocation of the ossicular chain caused by road fatalities. Computed Tomography (CT) was performed either because of the presence of clinical symptoms associated with trauma of the temporal bone, or because of a hemotympanum discovered during a CT scan of the brain. Thirty-three fractures were detected: 19 longitudinal, 6 transverse, and 8 complex. An incudostapedial dislocation was also detected, together with a displacement of a stapedial prosthesis from the lenticular process of incus, and 3 incus-malleus dislocations associated with fractures. High resolution CT allows the precise definition of the course of the fractures, of the associated dislocation of the ossicular chain, and of facial nerve lesion, thus allowing a more accurate surgical intervention. In the examination of the temporal bone, high resolution CT is preferable to pluridirectional tomography because it is easier and faster to perform. Moreover, high resolution CT helps reduce the radiation dose, and yields higher-quality images with more accurate diagnostic information. High resolution CT also allows the brain and the temporal bone to be studied at the same time.

Abstract
The diagnostic utility of preoperative intravenous urography (IVU) carried out in patients with carcinoma of the large bowel is still controversial. In the period between 1978 and 1984 only 8 out of the 347 patients undergoing surgery for carcinoma of the large bowel showed urinary tract involvement at operation. IVU had been carried out in 106 patients before surgery. The survey results agreed with histological reports in 103 case records: 101 true negative, 2 true positive. Two false positive cases and one false negative were also found. Among the eight patients who at surgery revealed urinary tract involvement, only in three IVU had been proposed; in the remaining 5 cases it had not been requested. It may be suggested that the early recognition of colon carcinoma does not allow the neoplasia to further develop in the urinary tract, at least not in as high a percentage as in the past. We therefore deem it necessary to use at first less invasive and faster methods, such as echography, limiting IVU to those cases where a well-grounded clinical suspicion or a previously executed echography suggest deeper investigation.
