Abstract
INTRODUCTION A multi-centre study has been conducted, during 2005, by means of a questionnaire posted on the Italian Society of Emergency Medicine (SIMEU) web page. Our intention was to carry out an organisational and functional analysis of Italian Emergency Departments (ED) in order to pick out some macro-indicators of the activities performed. Participation was good, in that 69 ED (3,285,440 admissions to emergency services) responded to the questionnaire. METHODS The study was based on 18 questions: 3 regarding the personnel of the ED, 2 regarding organisational and functional aspects, 5 on the activity of the ED, 7 on triage and 1 on the assessment of the quality perceived by the users of the ED. RESULTS AND CONCLUSION The replies revealed that 91.30% of the ED were equipped with data-processing software, which, in 96.83% of cases, tracked the entire itinerary of the patient. About 48,000 patients/year used the ED: 76.72% were discharged and 18.31% were hospitalised. Observation Units were active in 81.16% of the ED examined. Triage programmes were in place in 92.75% of ED: in 75.81% of these, triage was performed throughout the entire itinerary of the patient; in 16.13% it was performed only symptom-based, and in 8.06% only on-call. Of the patients arriving at the ED, 24.19% were assigned a non-urgent triage code, 60.01% a urgent code, 14.30% a emergent code and 1.49% a life-threatening code. Waiting times were: 52.39 min for non-urgent patients, 40.26 min for urgent, 12.08 for emergent, and 1.19 for life-threatening patients.

Abstract
BACKGROUND Gadolinium derivatives are ionic paramagnetic contrast agents used to enhance magnetic resonance images, labeled as a pregnancy category C by the Food and Drug Administration because of a lack of epidemiological studies concerning first-trimester exposure. METHODS Prospective cohort study to determine whether gadolinium derivatives exposure in periconceptional period is a risk factor for pregnancy or fetal development. RESULTS We report the outcome of 26 pregnant women exposed to gadolinium derivatives in the first trimester without adverse effect on pregnancy and neonatal outcome. CONCLUSIONS Currently, this study represents the only prospective investigation of gadolinium derivatives in pregnancy, but more data are necessary to exclude a teratogenic risk.

Abstract
OBJECTIVE To investigate the role of pulsed electromagnetic field (PEMF) exposure parameters (exposure length, magnetic field peak amplitude, pulse frequency) in the regulation of proteoglycan (PG) synthesis of bovine articular cartilage explants. METHODS Bovine articular cartilage explants were exposed to a PEMF (75 Hz; 2 mT) for different time periods: 1, 4, 9, 24 h. Then, cartilage explants were exposed for 24 h to PEMFs of different magnetic field peak amplitudes (0.5, 1, 1.5, 2 mT) and different frequencies (2, 37, 75, 110 Hz). PG synthesis of control and exposed explants was determined by Na2-35SO4 incorporation. RESULTS PEMF exposure significantly increased PG synthesis ranging from 12% at 4 h to 17% at 24 h of exposure. At all the magnetic field peak amplitude values, a significant PG synthesis increase was measured in PEMF-exposed explants compared to controls, with maximal effect at 1.5 mT. No effect of pulse frequency was observed on PG synthesis stimulation. CONCLUSIONS The results of this study show the range of exposure length, PEMF amplitude, pulse frequency which can stimulate cartilage PG synthesis, and suggest optimal exposure parameters which may be useful for cartilage repair in in vivo experiments and clinical application.

Abstract
The present study assesses the adaptation of a group of female patients with either manifest or suspected breast cancer who have undergone Magnetic Resonance Imaging (MRI) after receiving psychological support. Several studies in literature have reported the effectiveness of such support in reducing anti-oxidant and depression aspects related to MRI. Two random groups of patients, from the Service of Diagnostics Imaging of the Oncological Unit of the Regina Elena Institute of Rome, were enrolled. The experimental group (EG) received routine information together with extra psychological. The control group (CG) received only routine information. All the patients underwent a psychological evaluation, before (TO) and after (T1) the exam. The following evaluation instruments were used: the Crown Crisp Experimental Index (C.C. E.I.), the State-Trait Anxiety Inventory (S.T.A.I. Y1-Y2) and the Self Rating Depression Scale (S.D.S.) for TO and the State-Trait Anxiety Inventory (S.T.A.I. Y1 and the Self Rating Depression Scale (S.D.S.) for T1. Results prior to the MRI exam (TO), show that the women receiving extra information and emotional support (EG) suffer considerably less anxiety and depression compared to the control group. Results after the MRI exam (T1), indicate that the way the exam is carried out is also relevant in reducing anxiety. The level of anxiety, however, was significantly lower in the experimental group compared to the control. Depression levels, on the other hand, remained unaltered. Our results indicate that a psychological intervention aimed at providing more information and giving more emotional support helps patients adapt with a reduction of anxiety and depression.

Abstract
Most of the clinical manifestations of the antiphospholipid syndrome (APS) can be related to thrombotic events; however, placental thrombosis cannot explain all of the pregnancy complications that occur in women with this syndrome. In this regard, it has been hypothesized that antiphospholipid (aPL) antibodies can directly attack trophoblasts, but it is still unclear what pathogenetic mechanisms play a role and which aPL antibodies subpopulations are involved. Although it has been assumed that aPL antibodies are directed against anionic phospholipids (PLs), current advances in the field suggest that antibodies to PL-binding plasma protein such as beta2-glycoprotein-I (beta2-GPI) are the clinically relevant aPL antibodies. It appears that following the attachment of beta2-GPI to PLs, both molecules undergo conformational changes that result in the exposure of cryptic epitopes within the structure of beta2-GPI allowing the subsequent binding of antibodies. aPL antibodies detected by anti-beta2-GPI assays are associated with fetal loss. However, there is still debate on how the antibodies might induce the obstetrical manifestations. The significantly improved outcome of pregnancies treated with heparin has stimulated interest in the drug's mechanisms of action. Several mechanisms could explain its beneficial effects, because in addition to a direct effect of heparin on the coagulation cascade, it might protect pregnancies by reducing the binding of aPL antibodies, reducing inflammation, facilitating implantation and/or inhibiting complement activation. Further investigations are needed to better understand how aPL antibodies induce obstetric complications and to better clarify the functional role of heparin in the human placenta leading to more successful therapeutic options.

Abstract
Cultured mouse D3 embryonic stem (ES) cells differentiating into embryoid bodies (EBs) expressed several Wnt isoforms, nearly all isotypes of the Wnt receptor Frizzled and the Wnt/Dickkopf (Dkk) co-receptor low-density lipoprotein receptor-related protein (LRP) type 5. A 4-day treatment with retinoic acid (RA), which promoted neural differentiation of EBs, substantially increased the expression of the Wnt antagonist Dkk-1, and induced the synthesis of the Wnt/Dkk-1 co-receptor LRP6. Recombinant Dkk-1 applied to EBs behaved like RA in inducing the expression of the neural markers nestin and distal-less homeobox gene (Dlx-2). Recombinant Dkk-1 was able to inhibit the Wnt pathway, as shown by a reduction in nuclear beta-catenin levels. Remarkably, the antisense- or small interfering RNA-induced knockdown of Dkk-1 largely reduced the expression of Dlx-2, and the neuronal marker beta-III tubulin in EBs exposed to RA. These data suggest that induction of Dkk-1 and the ensuing inhibition of the canonical Wnt pathway is required for neural differentiation of ES cells.

Abstract
Mitoxantrone is an antineoplastic agent considered a potential human teratogen because of its mechanism of action and is classified by the US Food and Drug Administration in pregnancy category risk D. In the literature there are only four cases of women exposed to the drug in late pregnancy. We report the first case of mitoxantrone therapy in the first trimester and during the pregnancy. A 41-year-old woman affected with multiple sclerosis, conceived during therapy and continued mitoxantrone until 29 weeks and 3 days of her pregnancy. She delivered by cesarean section at 39 weeks a growth restricted female baby weighing 1950g without evidence of congenital malformations.

Abstract
Maternal thrombophilias increases the risk of an adverse pregnancy outcome. An extensive literature review highlights the role of inherited and acquired thrombophilic disorders in spontaneous abortion, both early and late, recurrent or isolate, in intrauterine growth retardation, in placenta abruption, in pre-eclampsia and in venous thromboembolism. We have particularly focused attention on the following factors: antithrombin III (ATIII), proteins C (PC) and S (PS) deficiencies, genetic mutations particularly factor V Leiden (FVL), prothrombin gene G20210A (PTM) and the thermolabile variant of the methylene tetrahydrofolate reductase C677T (MTHFR) gene, lupus anticoagulant (LAC) and anticardiolipin antibodies, VIIIc factor, hyperhomocysteinemia and acquired activated protein C resistance. Appropriate treatment can improve pregnancy outcome without teratogenic effects.

Abstract
Heparin is used widely for the prevention of pregnancy loss in pregnant women with thrombophilia. However, it is still unknown if heparin may be able to affect trophoblast functions. Therefore, we investigated the hypothesis that low-molecular weight heparin (LMWH) might regulate in vitro trophoblast invasiveness and placental production of matrix metalloproteinases (MMPs) and tissue inhibitors (TIMPs). In the first-trimester placental tissue, the MMP-9 expression was observed in both villous and extravillous cytotrophoblast cells, and MMP-2 mainly in villous cytotrophoblast. In human choriocarcinoma cells (JAR), MMP-2 was the dominant form. Heparin significantly enhanced both pro-MMPs and the active forms, and increased Matrigel invasiveness of extravillous trophoblast and choriocarcinoma cells. In choriocarcinoma cells the heparin effect was also indirect, inducing a significant decrease in TIMP-1 and TIMP-2 protein expressions and mRNAs. The present data suggest that the increase in trophoblast invasion by heparin is due to a specific protein playing a role in placental invasion. These observations may help in understanding the effects of heparin treatment during pregnancy.

Abstract
Rubella is the first virus demonstrated as a teratogen. There is a high risk to develop congenital rubella syndrome (CRS) if the infection occurs in the first part of pregnancy, particularly in women without specific immunological protection. Specific therapies to prevent CRS are not available. Many developed countries have specific vaccination programs and maternal rubella is rare. However, in developing countries or where campaigns of rubella surveillance and preconceptional vaccination are inadequate, there are still cases of CRS registered despite primary possibilities of prevention. Maternal infection is not indicative of vertical transmission in 100% of cases, and damage does not necessarily occur in all cases of fetal infection. This is the reason why an adequate prenatal counselling is mandatory, particularly in cases of proven maternal infection. Advanced prenatal diagnostic techniques, invasive or not, should be offered to the women especially in order to distinguish the cases without fetal damage. Prevention of voluntary interruption of pregnancy for the latter or in case of maternal false IgM rubella antibody positivity or IgM "chronic carrier" patients is mandatory. World wide, the aim is to perform an adequate primary prevention through vaccination of childbearing age women without specific immunological protection.

Abstract
AIM Many women exposed to completely innocuous agents during pregnancy have a high perception of adverse effects to such an extent that they may interrupt their pregnancy. The objective of our study is to evaluate the importance of the perception of the risk level in making the decision to end the pregnancy and the relevance that a teratology consultation can have in preventing unmotivated terminations of pregnancy METHODS We carried out a survey on 350 women in Rome who voluntarily interrupted their pregnancy to evaluate the prevalence due to presumed teratogen. Contemporarily we studied the pregnancy outcomes, the clinical, the psychological and the socio-economic factors of 142 women who contacted our Teratology Information Service (TIS) in the 1(st)trimester of pregnancy because suspected of teratogen exposure: 72 decided to terminate their pregnancy, whereas 70 were used as a control group. RESULTS On 350 women who voluntarily interrupted their pregnancy, 4 cases (1.4%) reported exposure to a suspected teratogen, but our evaluation determined only 1 case. On 72 women decided to terminate their pregnancy and who contacted our TIS, after counselling 73% continued their pregnancy with respect to 97% of the control group. Those women who interrupted their pregnancy did so because of personal reasons independently to or the type of exposure or the risk attributed by us. CONCLUSIONS From our data it appears that a percentage of voluntary abortions is related to suspected teratogen exposure and that TIS are effective in the prevention of this kind of voluntary abortions caused by groundless fears.

Abstract
Relatively few attempts have been made in the past to isolate and expand lymphatic endothelial cells (LECs). Recently this task has become feasible thanks to the identification of new lymphatic markers such as Podoplanin, Lyve-1, Prox-1 and D2-40. Using a two-step purification method based on the sorting of endothelial cells with Ulex Europaeus Agglutinin 1-coated beads followed by purification with monoclonal antibody D2-40, we were able to purify and in vitro expand human derived LECs from tissues such as lymph node, spleen, thymus, palatine tonsil and iliac lymphatic vessels. The isolated LECs were expanded on collagen type 1 and fibronectin coated flasks for up to 8-10 passages and then analyzed for phenotypic and functional properties. LECs were able to form a capillary like network, when seeded on Cultrex BME, indicating their capability to form lymphatic vessels in vitro. Comparative studies were performed, and we found that specific lymphatic and vascular markers were differentially expressed by LECs prepared from different sources, clearly demonstrating the phenotypic heterogeneity of LECs from different organs and different segments of the lymphatic vasculature. We here propose a new technique to make available ready sources of abundant well-characterized human LECs to examine normal profiles and behavior to compare with abnormal conditions.

Abstract
The present paper is a review of the data available in the literature concerning the prenatal exposure to radiation evaluating the reported teratogenic effect. We have particularly focused on the fetal effects of maternal ionising radiation exposure, both diagnostic and occupational, particularly in terms of congenital anomalies and birth weight. Ionising radiation represents a possible teratogen for the fetus, but this risk has been found to be dependent on the dosage and the effects correlatable to the gestational age at exposure. Recently, of particularly note is the fact that maternal thyroid exposure to diagnostic radiation has been associated with a slight reduction in the birth weight. Inadvertent exposure from diagnostic procedures in pregnancy doesn't usually increase the natural risk of congenital anomalies but creates a considerable state of maternal anxiety. Diagnostic radiological procedures should be avoided in pregnant women unless the information cannot be obtained by other techniques.

Abstract
OBJECTIVES To report our personal experience in the surgical treatment of cholesteatoma in children with Down syndrome. STUDY DESIGN Retrospective study. SETTING Tertiary care otology and skull base centers. PATIENTS Nine patients with Down syndrome were surgically treated for cholesteatoma. Two patients had bilateral disease, resulting in a total of 11 ears surgically treated. INTERVENTION A canal-wall-up mastoidectomy was performed in two ears; in eight of the ears, a canal-wall-down mastoidectomy was carried out and a modified Bondy procedure was performed in one ear. RESULTS Residual cholesteatoma was found in one ear after the canal-wall-up mastoidectomy and recurrent cholesteatoma developed in another ear, also after canal-wall-up mastoidectomy. The recurrence required conversion to canal-wall-down mastoidectomy. One patient developed a perforation of the neotympanic membrane that had to be revised. CONCLUSIONS Cholesteatoma in children with Down syndrome is a challenging entity for the otologic surgeon. Otolaryngologists should always suspect a cholesteatoma in each child with Down syndrome presenting warning symptoms such as otorrhea and hearing loss. If there is any doubt on inspection, further imaging studies (high-resolution computed tomography) are necessary. To the best of our knowledge, the current study is the first report to document the surgical treatment of cholesteatoma in subjects with Down syndrome.

Abstract
Postpartum hemorrhage, frequently due to uterine atony, is an important cause of maternal death and morbidity. The knowledge of causes, of antenatal and intrapartum risk factors and of physiopathological changes in hemodynamics and coagulation during pregnancy are essential for the management of the condition. At the present time, many efforts are made to organize a multidisciplinary approach to this complication of delivery involving clinical and laboratory staffs, since the rapid correction of hypovolemia, the diagnosis and treatment of defective coagulation, the surgical and pharmacological control of bleeding are mandatory. Several medical options have been developed and the surgical management includes traditional and newer conservative procedures with variable success rates. The developments in the treatment of postpartum hemorrhage may reduce hysterectomy that is to be considered the last resort to resolve the hemorrhage in some cases. In the modern management of postpartum hemorrhage protocols and guidelines should be available in every delivery room.

Abstract
An adverse influence on reproductive life and obstetric complications are known to occur in women with celiac disease (clinical and subclinical disease) or inflammatory bowel diseases. Treatment can improve the pregnancy outcome; therefore, it is advisable that a clinical evaluation is performed by a joint team of obstetricians, internists and surgeons. The preconception clinical evaluation of the affected women is useful to focus on the different clinical aspects of the disease and to indicate specific therapeutic strategies. In this study a review of the literature regard to celiac disease and inflammatory bowel disease in pregnancy is presented.

Abstract
Apoptosis was induced in cultured cerebellar granule cells by lowering extracellular K+ concentrations (usually from 25 to 10 mM). The apoptotic phenotype was preceded by an early and transient increase in the intracellular levels of the disialoganglioside, GD3, which behaves as a putative pro-apoptotic factor. We examined whether activation of Fas receptor mediates the increase in GD3 formation in granule cells committed to die. Degenerating granule cells showed increased expression of both Fas receptor and its ligand (Fas-L), at times that coincided with the increase in GD3 levels and the induction of GD3 synthase mRNA. Addition of neutralizing anti-Fas-L antibodies reduced the extent of 'low-K+'-induced apoptosis and abolished the increase in GD3 levels and GD3 synthase mRNA. Similar reductions were observed in cultures prepared from gld or lpr mice, which harbor loss-of-function mutations of Fas-L and Fas receptor, respectively. In addition, exogenous application of soluble Fas-L further enhanced both the increase in GD3 formation and cell death in cultured granule cells switched from 25 into 10 mM K+. We conclude that activation of Fas receptor is entirely responsible for the increase in GD3 levels and contributes to the development of apoptosis by trophic deprivation in cultured cerebellar granule cells.
