Abstract
After the discussion of a straightforward narrative description of the pre-surgical steps required before actual incision in the semi-sitting position1, using vestibular schwannoma surgery as an example, the authors intend likewise to provide a narrative description of the steps following incision, for safe resection of vestibular schwannomas, again attempting to simplify a complex procedure into a more reproducible one. Vestibular schwannoma surgeries are known to be intrinsically related to complications due to their intimate relationship to cranial nerves and vessels as well as brainstem structures in the posterior fossa. It is therefore paramount not only to be familiar with the anatomical and surgical nuances of the procedure, but having an easy-to-follow strategy to significantly reduce complications rate to a minimum. The authors have therefore divided the surgical steps into five major momentums of the procedure, from skin disruption and subcutaneous tissue dissection and retraction, through craniotomy, dural opening, tumor resection with internal acoustic meatus opening, and final closure. Enumeration of the steps, therefore, serve as a facilitated guide for the surgical steps that can be reproduced time and again for better surgical outcomes and the video supplement serves as a useful visual guide for improved understanding of the distinct phases of the surgical intervention.

Abstract
Cervical spondylotic myelopathy (CSM) can be successfully decompressed via either anterior cervical corpectomy and fusion (ACCF) or posterior laminectomy with fusion (LMF). However, few studies have compared the isolated effect of both techniques on cervical sagittal balance, a surrogate end point for clinical outcomes.We aimed to compare the sagittal balance radiological outcomes of ACCF against LMF. A case-matched controlled study of radiological cervical alignment parameters (C0-2, C2-3, index angles, T1 slope, and sagittal vertical axis (SVA)) in two groups of patients was performed by using pre- and postoperative neutral cervical X-rays.In total, 34 patients were enrolled (ACCF n = 17; LMF n = 17). The mean preoperative C2-7 angle was similar (11.58 ± 16.00° for ACCF; 13.36 ± 12.21° for LMF) in both cohorts. Both led to a loss of lordosis (-2.68 ± 13.8°, p = 0.43; -2.94 ± 11.5°, p = 0.31, respectively). At the C0-2, the two operations induced opposite variations (-0.9 ± 8.0°, p = 0.709 for ACCF; 3.5 ± 15.4°, p = 0.357 for LMF). ACCF led to a significant increase in SVA (7.1 ± 11.9 mm, p = 0.002). The C2-3 disk angle more pronouncedly increased with LMF.Both techniques show an equivalent kyphotic effect, with a greater disadvantage for ACCF. The negative impact on SVA changes is greater with ACCF. Both affect the C0-2 unit, with a tendency for kyphosis with ACCF and one for lordosis with LMF. When choosing the appropriate decompression and fusion technique, preoperative sagittal balance parameters should be included in the decision-making process.

Abstract
Cervical spondylosis is the leading cause of cervical myelopathy. When surgery is indicated, it is commonly addressed through an anterior or posterior cervical approach, such as cervical discectomy and fusion (ACDF) or laminectomy and fusion (LMF). Besides their own merits, each one has specific approach- or device-related complications, such as dysphagia, significant postoperative pain, wound infection, adjacent segment degeneration (ASD), and pseudoarthrosis. Through a tissue-sparing minimally invasive technique, posterior cervical fusion (PCF) has shown unfolding compelling evidence of biomechanical stability, good clinical outcomes, and high fusion rates, with fewer complications and better econometrics. On the basis of our own experience, we discuss here the indications, advantages, and drawbacks of minimally invasive PCF.

Abstract
The armamentarium of surgical treatment options for lumbar spondylolisthesis (LS) includes decompression alone, stabilization with interlaminar devices, or instrumented fusion, through open or minimally invasive approaches. Despite its safe profuse use in distinctive lumbar spine disorders, using percutaneous pedicle screws (PPSs) alone to stabilize LS has never been described before. We performed a retrospective study of prospectively collected data, enrolling 24 patients with LS and scrutinizing clinical and radiological outcomes. A statistically significant decrease in visual analog scale (VAS) scores (p < 0.001) and Oswestry Disability Index (ODI) scores (p < 0.001) was observed, as was a reduction in the intake of acetaminophen after surgery (p = 0.022). In the long-term, PPS effectively reduced the index-level range of motion (p < 0.001), reduced preoperative slippage (p = 0.03), and maintained foraminal height, thus accounting for the positive clinical outcomes. It induced a significant segmental kyphotic effect (p < 0.001) that was compensated for by a favorable increase in the pelvic incidence minus lumbar lordosis (PI-LL) index (0.028).

Abstract
Spinal intradural extramedullary (ID-EM) tumors are pathologies widely treated through a classical open approach. However, minimally invasive surgery is gaining traction as a comparable treatment option because it carries less morbidity and may reduce healthcare costs.This study aimed to compare the clinical and functional outcomes of open versus minimally invasive approaches for patients with ID-EM tumors. We performed a retrospective analysis on prospectively collected data from patients with ID-EM tumors submitted to surgery. Baseline features and operative variables were compared, including surgery duration and estimated blood loss (EBL). Postoperative data covered tumor histology, length of stay (LOS), complication(s), and neurological status (Medical Research Council (MRC) scale) at the last follow-up.In total, 46 patients were included: 30 (65.2%) operated through an open approach and 16 (34.8%) through a minimally invasive surgical (MIS) approach. The predominant histology type was schwannomas (43.5%). Lesions more frequently affected the lumbar spine (34.8%). The tumor dimensions were similar in both cohorts. The minimally invasive approach was on average 76.7 min faster and correlated positively with less EBL (140 mL less than that of the open approach). Patients in the MIS group had shorter LOSs (5.63 days vs. 17.27 days) and had fewer postoperative complications. No significant difference in functional outcome was found.MIS is as effective as the traditional approach in achieving comparable functional outcomes, with advantages such as shorter surgery durations, less blood loss, and shorter hospital LOSs.

Abstract
The use of plant elicitors for controlling Pseudomonas syringae pv. actinidiae (Psa), the etiological agent of the kiwifruit bacterial canker (KBC), has been analysed in the past and, while salicylic acid (SA) seems to decrease disease susceptibility, methyl jasmonate (MJ) shows an opposite effect. However, the metabolic and genomic responses of Psa-infected plants following elicitation with these two compounds, as compared with non-elicited Psa-inoculated plants, are poorly understood, being the focus of this study. Micropropagated A. chinensis 'Hayward' plants were elicited with MJ or SA, and further inoculated with Psa. Fifteen days post-inoculation, Psa population in MJ-treated plants was increased by 7.4-fold, whereas SA elicitation led to decreased Psa colonization (0.5-fold), as compared with non-elicited inoculated plants. Additionally, elicitation with MJ or SA generally decreased polyphenols and lignin concentrations (by at least 20%) and increased total proteins (by at least 50%). MJ led to the upregulation of SOD, involved in plant antioxidant system, and reporter genes for the jasmonic acid (JA) (JIH and LOX1), abscisic acid (SnRK), SA (ICS1), and ethylene (ACAS1, ETR1 and SAM) pathways. Moreover, it increased ABA (40%) and decreased carotenoids (30%) concentrations. Contrastingly, comparing with non-elicited Psa-inoculated plants, SA application resulted in the downregulation of antioxidant system-related genes (SOD and APX) and of reporter genes for ethylene (ETR1) and JA (JIH and ETR1). This study contributes to the understanding of potential mechanisms involved in kiwifruit plant defences against Psa, highlighting the role of the JA, ABA and ethylene in plant susceptibility to the pathogen.

Abstract
Hypertension (HTN) in children and adolescents is an important pathology, of, guarded prognosis, associated with modifiable and non-modifiable factors. The estimated prevalence is around 3.5% which increases progressively with age. The ideal method for its diagnosis is the measurement of blood pressure (BP) with auscultatory instruments. According to the American Academy of Pedia trics (AAP), BP should be measured in children older than three years of age once a year, and in children younger than three years of age if they present risk factors. Once the HTN is confirmed, the evaluation should be directed towards the detection of a causative disease and/or the search for risk factors associated with a primary HTN. The objective of treating primary and secondary HTN in pediatrics is to achieve a BP level that decreases the risk of target organ damage. Therapeutic op tions include treatment according to specific etiology, non-pharmacological and pharmacological one. This paper presents the position of the Chilean Society of Pediatrics Nephrology Branch with the aim of guiding pediatricians and pediatric nephrologists in the correct management of HTN in childhood. In this second part, recommendations on antihypertensive treatment are presented with an emphasis on lifestyle changes.

Abstract
Renal transplantation (RTx) is an effective therapy to improve clinical outcomes in pediatric patients with terminal chronic kidney disease. However, chronic immunosuppression with glucocorticoids (GCs) reduces bone growth and BMD. The mechanisms causing GC-induced growth impairment have not been fully clarified. Fibroblast growth factor 23 (FGF23) is a peptide hormone that regulates phosphate homeostasis and bone growth. In pathological conditions, FGF23 excess or abnormal FGF receptors (FGFR) activity leads to bone growth impairment. Experimental data indicate that FGF23 expression is induced by chronic GC exposure. Therefore, we hypothesize that GCs impair bone growth by increasing FGF23 expression, which has direct effects on bone growth plate. In a post hoc analysis of a multicentric randomized clinical trial of prepubertal RTx children treated with early GC withdrawal or chronic GC treatment, we observed that GC withdrawal was associated with improvement in longitudinal growth and BMD, and lower plasma FGF23 levels as compared with a chronic GC group. In prepubertal rats, GC-induced bone growth retardation correlated with increased plasma FGF23 and bone FGF23 expression. Additionally, GC treatment decreased FGFR1 expression whereas it increased FGFR3 expression in mouse tibia explants. The GC-induced bone growth impairment in tibiae explants was prevented by blockade of FGF23 receptors using either a pan-FGFR antagonist (PD173074), a C-terminal FGF23 peptide (FGF23180-205) which blocks the binding of FGF23 to the FGFR-Klotho complex or a specific FGFR3 antagonist (P3). Finally, local administration of PD173074 into the tibia growth plate ameliorated cartilage growth impairment in GC-treated rats. These results show that GC treatment partially reduces longitudinal bone growth via upregulation of FGF23 and FGFR3 expression, thus suggesting that the FGF23/Klotho/FGFR3 axis at the growth plate could be a potential therapeutic target for the management of GC-induced growth impairment in children.

Abstract
Albuminuria affects millions of people, and is an independent risk factor for kidney failure, cardiovascular morbidity and death. The key cell that prevents albuminuria is the terminally differentiated glomerular podocyte. Here we report the evolutionary importance of the enzyme Glycogen Synthase Kinase 3 (GSK3) for maintaining podocyte function in mice and the equivalent nephrocyte cell in Drosophila. Developmental deletion of both GSK3 isoforms (α and β) in murine podocytes causes late neonatal death associated with massive albuminuria and renal failure. Similarly, silencing GSK3 in nephrocytes is developmentally lethal for this cell. Mature genetic or pharmacological podocyte/nephrocyte GSK3 inhibition is also detrimental; producing albuminuric kidney disease in mice and nephrocyte depletion in Drosophila. Mechanistically, GSK3 loss causes differentiated podocytes to re-enter the cell cycle and undergo mitotic catastrophe, modulated via the Hippo pathway but independent of Wnt-β-catenin. This work clearly identifies GSK3 as a critical regulator of podocyte and hence kidney function.

Abstract
Aims and background High ferritin serum levels have been reported in patients suffering from various malignancies. The aim of this study was to evaluate the role of ferritinemia in the preoperative diagnosis of ovarian carcinoma. Methods Between March 1993 and September 1996, 60 patients suffering from ovarian carcinoma were surgically treated at our Department. Their ferritin serum levels were measured preoperatively by a solid-phase, two-site chemiluminescent immunometric assay and compared with those of a group of 60 healthy, age-matched, non pregnant controls. Results The mean serum concentration of ferritin was 54.7 ± 7.8 ng/ml (range, 14–135) in healthy controls and 112.3 ± 21.2 ng/ml (range, 9–947) in patients with ovarian carcinoma. The difference was statistically significant (P = 0.005, X2 test = 7.951). Serum ferritin was elevated preoperatively (cutoff ≥ 120 ng/ml) in 18/60 patients with malignancy (sensitivity 30%), whereas the CA 125 levels were above the cutoff in 53/60 patients (sensitivity 88.3%). Only 2/60 women of the control group had ferritin titers > 120 ng/ml (specificity 96.7%). The ferritin levels increased with advancing disease stage; no significant correlation was found between ferritin concentration and neoplastic histology and grading. The mean serum iron levels were also measured preoperatively in patients with ovarian carcinoma and healthy controls. They were 57.2 ± 3.8 and 66.3 ± 2.61 μg/dl, respectively, and the difference was not significant (P = 0.655, X2 test= 0.200). Conclusions The present study underlines that although ferritin shows an elevated specificity, its low sensitivity does not suggest any true usefulness as a tumor marker in epithelial ovarian cancer.

Abstract
This paper presents a novel poly(dimethylsiloxane) (PDMS) microfluidic immunosensor that integrates a complementary metal-oxide-semiconductor (CMOS) optical detection system for a rapid and highly-sensitive quantification of salivary cortisol. The simple and non-invasive method of saliva sampling provides an interesting alternative to the blood, allowing a fast sampling at short intervals, relevant for many clinical diagnostic applications. The developed approach is based on the covalent immobilization of a coating antibody (Ab), a polyclonal anti-IgG, onto a treated PDMS surface. The coating Ab binds the capture Ab, an IgG specific for cortisol, allowing its correct orientation. Horseradish peroxidase (HRP)-labelled cortisol is added to compete with the cortisol in the sample, for the capture Ab binding sites. The HRP-labelled cortisol, bonded to the capture Ab, is measured through the HRP enzyme and the tetramethylbenzidine (TMB) substrate reaction. The cortisol quantification is performed by colorimetric detection of HRP-labelled cortisol, through optical absorption at 450nm, using a CMOS silicon photodiode as the photodetector. Under the developed optimized conditions presented here, e.g., microfluidic channels geometry, immobilization method and immunoassay conditions, the immunosensor shows a linear range of detection between 0.01-20ng/mL, a limit of detection (LOD) of 18pg/mL and an analysis time of 35min, featuring a great potential for point-of-care applications requiring continuous monitoring of the salivary cortisol levels during a circadian cycle.

Abstract
Cognitive functioning can be differentially modulated by components of the immune system. Interferon-γ (IFNγ) is a pro-inflammatory cytokine whose production is altered in many conditions displaying some degree of cognitive deficits, although its role in cognitive functioning is still unclear. Here we show that the absence of IFNγ selectively enhances cognitive behaviours in tasks in which the hippocampus is implicated. Moreover, the absence of IFNγ leads to volumetric and cell density changes that are restricted to the dorsal part of the hippocampus. In the dorsal hippocampus, the absence of this pro-inflammatory cytokine leads to an increase in the numbers of newly born neurons in the subgranular zone of the dentate gyrus (DG), an adult neurogenic niche known to support learning and memory, and to an enlargement of the dendritic arborization of DG granule and cornu ammonis (CA)1 pyramidal neurons. Moreover, it also modestly impacts synaptic plasticity, by decreasing the paired-pulse facilitation in the Schaffer collateral to CA1 pyramidal cell synapses. Taken together, our results provide evidence that IFNγ is a negative regulator of hippocampal functioning, as its absence positively impacts on dorsal hippocampus structure, cell density, neuronal morphology and synaptic plasticity. Importantly, these neuroplastic changes are associated with improved performance in learning and memory tasks. Therefore, blockage of the IFNγ signalling may present as promising therapeutic targets for the treatment of inflammation-associated cognitive dysfunction.

Abstract
BACKGROUND Glucocorticoid immunosuppressant therapy in pediatric kidney transplant (Tx) recipients does not allow the improvement of growth after Tx. OBJECTIVE To determine the effect of early steroid withdrawal (SW) on longitudinal growth, insulin sensitivity (IS), and body composition (BC). METHODS This was a prospective, randomized, multicenter study in Tx. Insulin-like growth factor (IGF)-I, IGF-binding protein 3 (IGFBP3), IS, and BC (DEXA/pQCT) were determined at baseline and up to 12 months after Tx. RESULTS A total of 30 patients were examined; 14 patients were assigned to the SW group (7 male, 7 female; 12 in Tanner stage I) and 16 patients were assigned to the steroid control (SC) group (10 male, 6 female;12 in Tanner stage I). Their chronological age was 7.8 ± 4.3 years, height was -2.3 ± 0.99 SD scores (SDS), and body mass index -0.3 ± 1.2 SDS. After 1 year, the SW group showed an increase in height SDS (+1.2 ± 0.22 vs. +0.60 ± 0.13 SDS in the SC group, p < 0.02), lower IGFBP3 (p < 0.05), cholesterol (p < 0.05), and higher high-density lipoprotein cholesterol (p < 0.05). SW patients had lower trunk fat with no differences in IS. Only in prepubertal patients, the SW group had lower glycemia (p < 0.05), very low-density lipoprotein cholesterol (p < 0.01), triglycerides (p < 0.05), triglycerides/glycemia index (TyG; p < 0.02), and better lean mass. Both groups showed an improvement in lean mass after kidney Tx. CONCLUSIONS SW improved longitudinal growth, lipid profile, and trunk and lean fat in Tx patients. In prepubertal recipients, the decrease in TyG suggests better IS.

Abstract
In the process of remediation of mine sites, the establishment of a vegetation cover is one of the most important tasks. This study tests two different approaches to manipulate soil properties in order to facilitate plant growth. Mine waste from Ingurtosu, Sardinia, Italy rich in silt, clay, and heavy metals like Cd, Cu, and Zn was used in a series of greenhouse experiments. Bacteria with putative beneficial properties for plant growth were isolated from this substrate, propagated and consortia of ten strains were used to inoculate the substrate. Alternatively, sand and volcanic clay were added. On these treated and untreated soils, seeds of Helianthus annuus, of the native Euphorbia pithyusa, and of the grasses Agrostis capillaris, Deschampsia flexuosa and Festuca rubra were germinated, and the growth of the seedlings was monitored. The added bacteria established well under all experimental conditions and reduced the extractability of most metals. In association with H. annuus, E. pithyusa and D. flexuosa bacteria improved microbial activity and functional diversity of the original soil. Their effect on plant growth, however, was ambiguous and usually negative. The addition of sand and volcanic clay, on the other hand, had a positive effect on all plant species except E. pithyusa. Especially the grasses experienced a significant benefit. The effects of a double treatment with both bacteria and sand and volcanic clay were rather negative. It is concluded that the addition of mechanical support has great potential to boost revegetation of mining sites though it is comparatively expensive. The possibilities offered by the inoculation of bacteria, on the other hand, appear rather limited.

Abstract
The surface lipopolysaccharide of gram-negative bacteria is both a virulence factor and a B cell antigen. Antibodies against O-antigen of lipopolysaccharide may confer protection against infection, and O-antigen conjugates have been designed against multiple pathogens. Here, we describe a simplified methodology for extraction and purification of the O-antigen core portion of Salmonella lipopolysaccharide, suitable for large-scale production. Lipopolysaccharide extraction and delipidation are performed by acetic acid hydrolysis of whole bacterial culture and can take place directly in a bioreactor, without previous isolation and inactivation of bacteria. Further O-antigen core purification consists of rapid filtration and precipitation steps, without using enzymes or hazardous chemicals. The process was successfully applied to various Salmonella enterica serovars (Paratyphi A, Typhimurium, and Enteritidis), obtaining good yields of high-quality material, suitable for conjugate vaccine preparations.

Abstract
Growth failure is almost inextricably linked with chronic kidney disease (CKD) and end-stage renal disease (ESRD). Growth failure in CKD has been associated with both increased morbidity and mortality. Growth failure in the setting of kidney disease is multifactorial and is related to poor nutritional status as well as comorbidities, such as anemia, bone and mineral disorders, and alterations in hormonal responses, as well as to aspects of treatment such as steroid exposure. This review covers updated management of growth failure in these children including adequate nutrition, treatment of metabolic alterations, and early administration of recombinant human growth hormone (GH).

Abstract
Prior to the introduction of the MenAfriVac™ serogroup A glycoconjugate vaccine in September 2010, serogroup A was the major epidemic disease-causing meningococcal serogroup in the African meningitis belt. However, recently serogroup X meningococcal (MenX) disease has received increased attention because of outbreaks recorded in this region, with increased endemic levels of MenX disease over the past 2 years. Whereas polysaccharide-protein conjugate vaccines against meningococcal serogroups A, C, W and Y (MenA, MenC, MenW, MenY) are on the market, a vaccine able to protect against MenX has never been achieved. The structure of serogroup A, C, W and Y meningococcal polysaccharides has been already fully elucidated by NMR. MenX capsular polysaccharide (MenX CPS) structure is also documented but fewer characterization data have been published. We have applied here (1)H NMR, (31)P NMR and HPLC to evaluate the stability of MenX CPS in aqueous solution as compared to MenA capsular polysaccharide (MenA CPS). The stability study demonstrated that MenA CPS is more susceptible to hydrolytic degradation than MenX CPS. The different stereochemistry of the N-acetyl group at position C(2) of mannosamine (MenA CPS) and glucosamine (MenX CPS) respectively might play a fundamental role in this susceptibility to polysaccharide chain degradation. The satisfactory stability of MenX CPS predicts the possibility that a stable fully-liquid MenX polysaccharide or glycoconjugate vaccine could be developed.

Abstract
In this randomized controlled study, effectiveness, operative time, and acceptability of endometrial polypectomy were compared using an AlphaScope vs an office operative lens-based hysteroscope (LBH). One hundred fifty women with a diagnosis of endometrial polyp were operated on using an AlphaScope or LBH in the office setting. In 73 procedures using the AlphaScope (97.3%) and 68 using the LBH (90.7%), the polyp was successfully removed completely. In the AlphaScope group, 2 procedures were incomplete because of excessive endometrial mucosa thickness. In the LBH group, 3 procedures were incomplete because of difficulty in management of a large polyp, and 4 procedures were stopped because of patient pain and low compliance. Time to completion of the procedure and complete removal of the polyp was significantly shorter in the AlphaScope group than in the LBH group (p < .05). Similarly, the pain score at the end of the procedure was significantly lower in the AlphaScope group than in the LBH group (p < .05). The AlphaScope is an effective operative hysteroscope that increases the possibility of performing endometrial polypectomy in the office setting without anesthesia and improves the indications for and acceptability of office hysteroscopy.

Abstract
This prospective, comparative trial investigated the impact on mean change in height standard deviation score (SDS), acute rejection rate, and renal function of early steroid withdrawal in 96 recipients with 5 years of follow-up. Recipients under basiliximab induction and steroid withdrawal (SW: TAC/MMF; n = 55) were compared with a matched steroid control group (SC: TAC/MMF/STEROID, n = 41). SW received steroids until Day 6, SC decreased to 10 mg/m(2) within 2 months post-transplant. Five years after SW, the longitudinal growth (SDS) gain was 1.4 ± 0.4 vs. 1.1 ± 0.3 for SC group (p < 0.02). Height benefits in prepubertal and pubertal status in both groups were demonstrated in the delta growth trends (mixed model; p < 0.01). Biopsy-proven acute rejection in SW was 11% and 17.5%, SC (p: ns). Mean eGFR (ml/min/1.73 m(2)) at 5 years post-transplant was SW 80.6 ± 27.8 vs. 82.6 ± 25.1 for SC (p: ns). The death-censored graft survival rate at 1 and 5 years was 99 and 90% for SW; 98 and 96% for SC (p = ns). PTLD incidence in SW 3.3 vs. 2.5% in SC (p: ns). Five years post-transplant, early steroid withdrawal showed positive impacts on growth, stable renal function without increased acute rejection risk, and PTLD incidence.

Abstract
We demonstrate the cnoidal wave formation in a two-laser system with a saturable absorber in the cavity of one of the lasers. Another laser is used to activate the saturable absorber in order to control the pulse shape, width, intensity and frequency. Using the three-level laser model based on the Statz--De Mars equations, we show that for any value of the saturable absorber parameter there exists a certain modulation frequency for which the pulse shape is very close to a soliton shape with less than 5% error at the pulse base. Such a device may be prominent for optical communication and laser engineering applications.

Abstract
INTRODUCTION In the Puglia region (South Italy) about 200 new hospitalizations for cervical cancer are registered every year. The study investigated the frequency of Human Papillomavirus (HPV) infection and the genotype distribution of HPV in a sample of women with known cytology attending the outpatient clinics of four Gynecological Departments of the University of Bari over a four-year period (2005-2008). METHODS Cervical samples from 1,168 women were analyzed for the presence of HPV-DNA through Polymerase Chain Reaction (PCR) in L1 region and reverse hybridization. The cytological results were associated with HPV positivity and type-specific prevalence. RESULTS Overall, HPV infection was found in 355 (30.4%) women. HPV-DNA was found in 34.4% of women with a cytological diagnosis of ASCUS, in 46.8% of women with Low-grade Squamous Intraepithelial Lesion (LSIL) and in 87.0% of women with High-grade Squamous Intraepithelial Lesion (HSIL)/carcinoma. Also 16.0% of women with normal Pap smear were found to be HPV-DNA positive. The most common HPVgenotype was type 16 found in 27.3% of positives, followed by type 53 (11.5%), type 66 (9.2%) and type 31 (9.0%). HPV genotype 18 was found in 6.4% of positives. Types 16 or 18 were detected in about 34% (120/355) of all infected women, in about 33% of LSIL and in 60% of HSIL/ carcinoma HPV-positive women. Among low risk (LR) genotypes, type 61 was found in 10.7% of HPV positive women, type 62 in 8.4%, type 42 in 8.1% and type CP6108 in 7.8%. DISCUSSION AND CONCLUSIONS The findings of the study give evidence that HPV infection is frequent in the studied cohort of women. The most widespread genotypes found were 16 and 53. These data may represent a benchmark for future evaluation after the recent introduction of vaccination against HPV in 12-year-old girls.

Abstract
AIM The aim of this study was to determine the diagnostic accuracy of minihysteroscopy with fluid distention and vaginoscopic approach for the diagnosis of endometrial pathologies. METHODS This controlled clinical study was conducted on 930 women with endometrial abnormalities who referred to our Department of Obstetrics and Gynecology, University Medical School of Bari, to perform hysterectomy. One week before hysterectomy all the patients underwent minihysteroscopy with fluid distention. Histological diagnoses were compared with the hysteroscopic findings, and the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were determined. RESULTS Hysteroscopy was technically successful in all women and revealed sensitivity of 98%, specificity of 99%, a positive predictive value of 92%, a negative predictive value of 99%, and diagnostic accuracy of 99% for the diagnosis of endometrial carcinoma. CONCLUSIONS Size reduction of the hysteroscope is of greatest importance for reducing pain and risk of vasovagal reaction. In conclusion, the best approach in terms of ease, reliability, acceptability, and safety to patients in whom intrauterine exploration is indicated should be simple diagnostic mini-hysteroscopy using a small-diameter, rod lens hysteroscope with a single-flow diagnostic sheath, vaginoscopic approach, and fluid distention. In this way in about 90% of patients, a correct diagnosis and proper choice for eventual subsequent operative strategy can be obtained, without discomfort and risk.

Abstract
OBJECTIVE The cavum veli interpositi (CVI) is a space within the double-layered tela choroidea of the third ventricle. Occasionally, this space is fluid-filled and sonographically visible as an interhemispheric anechoic cyst. Because of its rarity, the incidence of CVI cyst is undetermined and the outcome of affected individuals has been found to be variable. The aim of this study was to report our experience of the sonographic findings and outcome of fetuses affected by CVI cysts. METHODS In five fetuses with a CVI cyst, we performed targeted prenatal ultrasound scans of intracranial structures and a detailed anatomical survey to rule out associated malformations. Follow-up consisted of neurological examination and neurosonography. RESULTS The CVI cyst appeared as a well-defined anechoic lesion without adjacent mass effect. In all fetuses the cyst was single and in two cases it enlarged slightly during pregnancy. The cyst was isolated in three fetuses and associated with borderline ventriculomegaly in two. A single umbilical artery was the only associated extracranial anomaly and this was detected in only one fetus. Neurosonography confirmed the presence of CVI cysts in all cases after delivery. During postnatal follow-up (range 10-48 months), the cyst regressed in one case within 1 month after delivery while the size of the others remained stable. No infant developed psychomotor disorders. CONCLUSIONS Prenatal sonographic diagnosis of CVI cysts is feasible. Its finding in isolation is consistent with favorable postnatal outcome.

Abstract
5587 Background: Chemoradiotherapy is the standard treatment of advanced cervical cancer. Neoadjuvant chemotherapy (NAC) may represent an alternative for locally advanced cervical cancer (LACC).This study was undertaken to evaluate the efficacy of NAC in young patients with squamous LACC. Methods: Since 2000 to 2008, 61 pts (mean age 43 yrs) with squamous LACC were treated with NAC and afterwards evaluated for radical surgery. Eligibility included proven histologically diagnosis of squamous cervical carcinoma, FIGO stage IB2/IIA>4cm/IIB, measurable disease, ECOG PS 0–2, no prior therapy and age under 49 years. All patients received TIP regimen (cisplatin 50 mg/m2 i.v. day 1, paclitaxel 175 mg/m2 over 3 hrs i.v.day1, ifosfamide 5,000 mg/m2 plus mesna 6,000 mg/m2 over 24 hrs i.v. day 1–2). Each cycle was repeated every 21 days. Patients were evaluated 4–6 weeks after the completion of the third cycle with the purpose to perform radical surgery according to clinical response. Results: 35pts (57.4%) were stage IB2; 9 (14.7%) were IIA >4cm; and 17 (27.9%) were IIB. After restaging the clinical results were: CR = 4/61 (6.6%), PR = 51/61 (83.6%); no response = 5/61 (8.2%); progression = 1/61 (1.6%). A total of 55 pts (90.1%) were eligible for surgery; 6/61 pts (9.8%) were submitted to curative radiotherapy (until 2004) or chemoradiotherapy. Pathological responses after surgery were: 4 pCR (7.3%); 46 pPR (83.6%); and 5 (9.1%) pPR with presence of positive surgical margins or metastatic lymph nodes. Out of 55 pts, 50 received 2 cycles of TIP regimen as a consolidation therapy before follow-up; 5 pts with incomplete pPR underwent radio/chemoradiotherapy. After NAC an overall downstaging of LACC was obtained in 50/61 pts (82.0%). In this group of pts at the median follow-up of 42 months (range 4–98) updated as of December 2008, the 3-years progression-free survival and overall survival are 85.9% and 82.0%, respectively. Conclusions: Our results indicate that TIP regimen-based NAC is an attractive option in young women with squamous LACC (IB2,IIA >4cm, IIB) that strongly desire surgery.The rate of patients with a prolonged remission of disease (82.0%) suggests that the clinical benefit of TIP regimen-based NAC followed by surgery may be comparable to chemoradiotherapy. No significant financial relationships to disclose.

Abstract
The vertical distribution of Hg and Pb were determined in a sediment core collected from the Sagua estuary (North Cuba) that receives input from the Sagua river, one of the most polluted rivers discharging into the Cuban coastal environment. Depth profiles of metal concentrations were converted to time-based profiles using the (210)Pb dating method and confirmed with the (137)Cs fallout peak. The mean mass accumulation rate was estimated to be 0.17+/-0.04 g cm(-2)y(-1) (mean sediment accumulation rate 0.52+/-0.13 cm y(-1)) and the core bottom was estimated to date back about 130 years. The historical sedimentary record showed a strong enrichment of mercury concentrations in the past decades, caused by the incomplete treatment of industrial wastes from a chlor-alkali plant with mercury-cell technology in the Sagua river basin. Lead fluxes to sediments showed a gradual increase from the 1920s to present, which agrees with a population increase in Sagua la Grande City. Fluxes of both metals have increased the past 25 years, with values reaching a maximum of 0.5 and 3.9 microg cm(-2)y(-1) for Hg and Pb, respectively.

Abstract
Gastrointestinal stromal tumors (GISTs) are among the most common mesenchymal tumors of the gastrointestinal tract. Diagnosis of GIST on ultrasound examination can be difficult because of their similarity in appearance to gynecological neoplasms. We present two cases of GIST originating from the small bowel and the stomach, which were preoperatively misdiagnosed as a uterine leiomyoma and an ovarian tumor, respectively. The ultrasonographic differential diagnosis of these pelvic masses is discussed.

Abstract
BACKGROUND Adverse events (AE) represent a significant clinical problem after infusion of cryopreserved HPC. However, the factors playing a role in the pathogenesis have not yet been fully established. METHODS We prospectively collected data on AE that occurred with 179 HPC infusions performed on patients affected with hematologic neoplasm after high-dose chemotherapy. The stem cell source was hemopoietic progenitor cells aphaeresis (HPC-A) in 157 cases and hemopoietic progenitor cell BM (HPC-BM) in 22 cases. In all cases, an endotoxin-free DMSO was used. RESULTS One or more AE were registered in 51/179 infusions (28.6%). The frequency of AE was higher after HPC-A than after HPC-BM (31.3% vs. 4.5%; chi(2) test, P =0.008). With univariate logistic regression, other factors found important for AE were age (P =0.028), number of total nucleated cells infused per kilogram (P =0.002), volume per kilogram infused (P =0.057), volume of packed RBC (P =0.019), a content of non-mononuclear cells >0.5 x 10(8)/kg (<P =0.0001) and actual time of infusion (P =0.058). When all aforementioned factors were evaluated with a multivariate logistic regression, only age of patient (P =0.024) and a content of non-mononuclear cells >0.5 x 10(8)/kg (P =0.0003) remained significant. A significant correlation existed between reduction of cardiac frequency both with volume per kilogram infused (r =0.221, P =0.02) and actual time of infusion (r =0.269, P =0.005). DISCUSSION Cardiovascular changes are influenced by volume per kilogram infused and by actual time of infusion, while non-cardiovascular AE are dependent on patient age and contamination by non-mononuclear cells in apheretic harvests.

Abstract
AIM The progressive appearance of specific embryological structures has been successfully used to define the ultrasonographic gestational age (GA). In our study we have revised this technique by comparing our results with the ones from Warren et al. obtained in 1989. Aim of the study is to evaluate the accuracy of this technique when applied working with new instrumentations and average skilled sonographers. METHODS Sixty-five pregnant women with correct GA ranging between 4 and 12 weeks have been observed between April 2003 and March 2004. We exposed them to an ultrasound examination looking for these structures in terms of presence/absence: gestational sac, yolk sac, embryo pole with cardiac activity, thromboencephalic cavity, falx cerebri and physiologic midgut herniation. We used transvaginal sonography (TVS) until 11 weeks of GA, from 11 weeks + 1 day we switched to transabdominal sonography (TAS). We have compared our results with the ones published by Warren et al. RESULTS Gestational sac's visualization has been possible between 4 weeks+3 days/5 weeks of GA. Yolk sac has been visualized between 5 weeks+4 days/6 weeks of GA, embryo with cardiac activity has been observed between 5 weeks+6 days/6 weeks+2 days of GA, romboencephalic cavity has been visualized between 7 weeks and 7 weeks+5 days, falx cerebri has been detected between 9 weeks+1 day/10 weeks+3 days. Visualization of physiologic midgut herniation has been possible between 8 weeks+3 days/8 weeks+6 days; it disappeared between 10 weeks+3 days/11 weeks +1 day. CONCLUSIONS Although the technological improvement in the US equipment in the last 15 years and the combination of TVS with TAS, there has been no advanced visualization of those single embryological structures. Indeed there has been a reduction of the time range during which those structures have been visualized. This improvement might have important practical implications in the ultrasonographic assessment of GA.

Abstract
Between 1989 and 2002, 178 renal transplants were performed in 168 pediatric patients in Chile. The mean age was 10.9 +/- 3.7 years (range 1 to 17.9). End-state renal disease etiologies were: congenital renal hypoplasia/dysplasia, chronic glomerulonephritis, and reflux nephropathy. Seventy received a graft from a living donor (LD), and 108 from a cadaveric donor (CD). Only 9% received antibody induction. Acute rejection episodes were reported in 76 patients: 38% in LD recipients and 48% in CD recipients (P = NS). One-, 3-, and 5-year graft survivals were 88%, 84%, and 76%, respectively, for LD and 86%, 79%, and 68% for CD recipients. Actuarial graft survival was significantly better among those patients with serum creatinine < 1 mg/dL at 1 year posttransplant compared with those with creatinine > 1 mg/dL (P < .05). The graft survival rate has improved from the first period (1989 to 1996) to the second period (1997 to 2002); (P = .05). Patient survival rates at 1, 3, and 5 years were 98%, 98%, and 98%, respectively, for LD, and 95%, 94%, and 94% for CD. Global height/age Z-score decreased from -0.7 at birth to -1.5 when dialysis started, and to -2.4 at the time of transplantation. The Z-score height/age at 1, 3, and 5 years posttransplantation was -2.25, -2.24, and -2.5. No significant differences were observed in transplant outcomes comparing patients younger than 7 years with those older ones. In conclusion, pediatric renal transplant has been performed in Chile with acceptable morbidity. The patient and graft survivals are similar to the reported international experience. In the last period there was a significant improvement in graft survival.
