Abstract
OBJECTIVES The safety of thiopurines and anti-tumor necrosis factor-α (TNF-α) drugs during pregnancy remains controversial, as the experience with these drugs in this situation is limited. Our aim is to assess the safety of thiopurines and anti-TNF-α drugs for the treatment of inflammatory bowel disease (IBD) during pregnancy. METHODS Retrospective, multicenter study in IBD patients. Pregnancies were classified according to the therapeutic regimens during pregnancy or during the 3 months before the conception: non-exposed group, pregnancies exposed to thiopurines alone (group A), and pregnancies exposed to anti-TNF-α drugs (group B). An unfavorable Global Pregnancy Outcome (GPO) was considered if pregnancy developed with obstetric complications in the mother and in the newborn. RESULTS A total of 187 pregnancies in the group A, 66 pregnancies in the group B, and 318 pregnancies in the non-exposed group were included. The rate of unfavorable GPO was different among the three groups (31.8% in non-exposed group, 21.9% in group A, and 34.8% in group B), being lower in pregnancies under thiopurines than among non-exposed (P = 0.01). The rate of pregnancy complications was similar among the three groups (27.7% in non-exposed, 20.9% in group A, and 30.3% in group B). The rate of neonatal complications was different among the three groups (23.3% in non-exposed group, 13.9% in group A, and 21.2% in group B), being lower in pregnancies under thiopurines than among non-exposed (P = 0.01). In the multivariate analysis, the treatment with thiopurines (odds ratio = 0.6; 95% confidence interval = 0.4-0.9, P = 0.02) was the only predictor of favorable GPO, whereas maternal age >35 years at conception was the only predictor of unfavorable GPO. The treatment with anti-TNF-α drugs was not associated with an unfavorable GPO. CONCLUSION The treatment with thiopurines and anti-TNF-α drugs does not seem to increase the risk of complications during pregnancy and does seem to be safe for the newborn.

Abstract
Femoral vessel injuries are amongst the most common vascular injuries admited in busy trauma centers. The evolution of violence and the increase in penetrating trauma from the urban battlefields of city streets has raised the incidence of femoral vessel injuries, which account for approximately 70% of all peripheral vascular injuries. Despite the relatively low mortality associated with these injuries, there is a high level of technical complexity required for the performance of these repairs. Similarly, they incur low mortality but are associated with significantly high morbidity. Prompt diagnosis and treatment are the keys to successful outcomes with the main goals of managing ischemia time, restoring limb perfusion, accomplishing limb salvage and instituting rehabilitation as soon as possible.

Abstract
INTRODUCTION Vascular injuries in branch vessels of the popliteal artery, such as the tibioperoneal trunk, and shank vessels, such as anterior, posterior tibial, and peroneal vessels, occur in both blunt and penetrating trauma. Their management has evolved significantly in the past few decades. While their incidence is variable, limb loss and morbidity remain significant. MATERIAL AND METHODS Physical examination, along with measuring an Ankle-Brachial Index (ABI), is still sometimes all that is required for diagnosis and can expeditiously triage those that require urgent operation. Despite our technological advancements and newer algorithms for lower extremity vascular trauma, operative intervention and exposure still remain difficult and pose a great challenge for surgeons that normally do not operate on this area. CONCLUSIONS Shank vessel injuries still comprise a significant proportion of combat and civilian vascular injuries, and modern advances have led to a dramatic decrease in amputation rates.

Abstract
INTRODUCTION Injury to the iliac vessels poses a serious and frustrating treatment dilemma for all trauma surgeons. Generally, patients present in profound shock secondary to severe hemorrhage from either iliac arterial, venous, or combined injuries. Despite improvements in our emergency medical services (EMS), rapid transport, standard training of trauma surgeons, and improved technology, the morbidity and mortality from iliac vessel injuries remain high, ranging from 25 to 40 %. MATERIALS AND METHODS A systematic review of the literature, with emphasis placed on the diagnosis, treatment, and outcomes of these injuries, incorporating the author's experience. CONCLUSIONS Injuries to the iliac vessel remain a daunting task, even after great advances in anatomic injury grading and damage control as well as advances in surgical techniques and critical care. Despite all the advances in treatment and appropriate management strategies, the morbidity and mortality from iliac vessel injuries remain high, demonstrating the complex challenge their treatment presents to even the modern-day trauma surgeon.

Abstract
Parkinson's disease (PD) is diagnosed when striatal dopamine (DA) loss exceeds a certain threshold and the cardinal motor features become apparent. The presymptomatic compensatory mechanisms underlying the lack of motor manifestations despite progressive striatal depletion are not well understood. Most animal models of PD involve the induction of a severe dopaminergic deficit in an acute manner, which departs from the typical, chronic evolution of PD in humans. We have used 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administered to monkeys via a slow intoxication protocol to produce a more gradual development of nigral lesion. Twelve control and 38 MPTP-intoxicated monkeys were divided into four groups. The latter included monkeys who were always asymptomatic, monkeys who recovered after showing mild parkinsonian signs, and monkeys with stable, moderate and severe parkinsonism. We found a close correlation between cell loss in the substantia nigra pars compacta (SNc) and striatal dopaminergic depletion and the four motor states. There was an overall negative correlation between the degree of parkinsonism (Kurlan scale) and in vivo PET ((18)F-DOPA K(i) and (11)C-DTBZ binding potential), as well as with TH-immunoreactive cell counts in SNc, striatal dopaminergic markers (TH, DAT and VMAT2) and striatal DA concentration. This intoxication protocol permits to establish a critical threshold of SNc cell loss and dopaminergic innervation distinguishing between the asymptomatic and symptomatic parkinsonian stages. Compensatory changes in nigrostriatal dopaminergic activity occurred in the recovered and parkinsonian monkeys when DA depletion was at least 88% of control, and accordingly may be considered too late to explain compensatory mechanisms in the early asymptomatic period. Our findings suggest the need for further exploration of the role of non-striatal mechanisms in PD prior to the development of motor features.

Abstract
BACKGROUND Ciclosporin has proven to be effective in patients with corticosteroid-refractory ulcerative colitis (UC). When therapy with this drug fails, infliximab can be considered to avoid colectomy. The efficacy and safety of this sequential approach remain unknown. AIM To assess the efficacy and safety profile of treatment with infliximab after failure of ciclosporin in patients with a corticosteroid-refractory flare of UC. METHODS Retrospective review of medical records of patients with a corticosteroid-refractory flare of UC who did not respond to ciclosporin and received salvage therapy with infliximab within a month of discontinuing ciclosporin. The severity of the flare and response to the treatment were graded using the Lichtiger index. Cumulative rates of colectomy were calculated using Kaplan-Meier analysis. Cox regression analysis was performed to identify predictors of colectomy. To evaluate the safety profile of this treatment strategy, any adverse event occurring after the first infusion of infliximab was considered. RESULTS The study population comprised 47 patients with corticosteroid-refractory UC treated with infliximab after failure of ciclosporin. The median baseline Lichtiger index was 13. The mean time from the last ciclosporin dose to the first infliximab infusion was 6 days. After the first infliximab infusion, 13% of patients achieved remission, and 74% partial response. Of the 35 patients who received the third infliximab infusion, 60% achieved remission, and 37% partial response. Fourteen patients (30%) underwent colectomy. The rate of adverse events was 23%. One death occurred in a 40-year-old man who failed ciclosporin and infliximab and underwent surgery 10 days after the first infliximab infusion; he died of nosocomial pneumonia. CONCLUSIONS Treatment with infliximab makes it possible to avoid colectomy in two-thirds of corticosteroid-refractory UC patients in whom ciclosporin fails. However, the rates of adverse events and mortality mean that the decision to administer sequential therapy (ciclosporin-infliximab) should be taken on an individual basis.

Abstract
18 Background: The study of the sentinel node biopsy is a common method to assess axillary involvement before surgical resection. The OSNA assay based on reverse transcriptase loop mediated amplification (RT-LAMP) and quantification of cytokeratin 19 (CK19) mRNA allows a rapid intra-operative detection of the metastases in the sentinel lymph node in breast cancer patients. Pathologists considered micro metastases when the size of the node involvement was between 0.2 and 2 mm and the OSNA method assess micro metastases when the copy number of CK19 is between 250 and 5000. Methods: From a total of 341 patients in which sentinel node had been analyzed, we studied a series of 32 patients whose sentinel nodes had micro metastases assessed by OSNA and who underwent subsequent axillary dissection. Median breast tumour size was 1.6 cm, 10 patients (31%) had less than 1 cm in size and only 6 patients (19%) had >2 cm. 78% of patients shown positive oestrogen receptor and 14 patients (44%) had low Ki67 (<14%). The CK19 mRNA was quantified in all patients (32) resulting in a median value of 540 (210-4800). Results: The median value of the nodes removed by axillary dissection was 14 (9-19). We found tumor invasion in none of them by histopathological conventional study. Conclusions: Since we have found no axillary involvement when the sentinel node have micro metastases analyzed by the OSNA method it seems that quantitative measure of CK19 by OSNA may be a useful procedure in order to avoid axillary dissection, although it would be necessary to perform larger studies to demonstrate this effect.

Abstract
INTRODUCTION In this study, we attempt to find out the percentage of uninfected infants born to HIV-infected women and exposed in-utero and perinatally to Antiretroviral Treatment (ART) that show high lactate levels, or any other mitochondrial damage markers (such as hypertransaminasaemia or hyperamylasaemia), during the first three months of age. We shall also establish whether certain drugs used in-utero are associated with higher lactate, transaminase or amylase levels. METHODS We analysed the available data from 623 uninfected infants born in the Spanish FIPSE cohort that were born in the period 2000-2005. The normal values for lactate, transaminases and amylase were set according to AIDS Clinical Groups Trials toxicity tables for infants. RESULTS The percentages of children with high lactate levels at 0.5; 1.5 and 3 months of age were 48%, 51.4% and 43% among those infants with available data. Respectively, the percentages of children with high AST values were 13.2; 10.4 and 17.2%. The values for high ALT were 3.3%; 3.4% and 5%. The percentages for hyperamylasaemia were 0%; 0.6% and 2.6%. We found no significant difference among the drugs used in utero for the four analysed biochemical markers along the first three months of age. CONCLUSIONS We have found a high proportion of hyperlactataemia among infants exposed in-utero to ART, as shown in other cohorts of similar characteristics. No morbidity or mortality was communicated to the cohort analysis group. No ART drug among those used in-utero was statistically associated with a higher proportion of high lactate levels in these infants.

Abstract
INTRODUCTION Recent reports show that Antiretroviral Treatment (ART) during pregnancy does not affect somatic growth of children born to HIV-infected mothers, are reassuring. The aim of this study is to perform an anthropometric analysis of the uninfected children followed in the Spanish FIPSE cohort during their first 18 months of life, and to describe the possible risk factors during pregnancy that may influence low birth weight. METHODS The FIPSE cohort includes 8 public hospitals in Madrid, and prospectively follows children born to HIV-infected women at these hospitals. We collected data on 601 uninfected children, following standardised protocols, during their first 2 years of life. A P value<0.05 was considered statistically significant. Data from the Pablo Orbegozo Foundation were used to compare the means of our population with the standard weight, longitude an occipitofrontal circumference (OFC) of the Spanish population during the first 18 months of life. RESULTS The mean weight was 2766g (+/-590), and 2967g (+/-427) when premature neonates were excluded. The proportion of Intrauterine Growth Restriction among non- premature neonates was 19.8% (95% CI: 16.3-23.8). Children born to mothers that used illicit drugs weighed less: 2752g (+/-325) vs. 3002g (+/ 435), P<0.001, as did children born to mothers who smoked during pregnancy: 2842g (+/-363) vs. 3018g (+/-444), P>0.001. Maternal anaemia did not influence the low birth weight of the children when premature neonates were excluded. We found no statistically significant differences depending on the ART received during pregnancy. Children born to mothers who had CD4 > 500 cell /mm were heavier (2834g +/-503) than those whose mothers had CD4 of less than 200 cell/mm (2565g +/-702), P=0.008. These differences disappeared when premature neonates were excluded. Children born to mothers with undetectable viral load were heavier (2866g +/-532 vs. 2704g +/-588, P=0.005), but these differences also disappeared when the prematures were excluded from the analysis. Mean weight, length, and OFC of our population at birth (excluding premature neonates) were lower than the Spanish standards. (z for weight=-0.83; z for length =-1.02; z for OFC=-1.00), but these differences are not statistically significant and disappear at 18 months of age (z for weight=-0.08; z for height=-0.32; z for OFC=-0.31). The type of ART did not have any significant influence. DISCUSSION There is a very significant difference between the weight of the children born to mothers addicted to illicit drugs and the rest of the children. Similarly, the weight of the children born to smoking mothers is significantly lower. There was no association between maternal anaemia and the type of ART. The children of our population have lower weights, length and OFC at birth, but this may due to the high number of scheduled caesarean births, practised at 38 weeks of pregnancy (54.5%). Our children catch-up with anthropometric measurements during the first and second year of life, and these are similar to Spanish standards at 18 months old.

Abstract
INTRODUCTION Mother-to-child HIV transmission is currently around 1% in western countries, due to prevention measures. Antiretroviral drugs do have adverse effects, anaemia and myelosupression caused by AZT being the most observed effects. In the present study, we analyse the prevalence of anaemia and neutropenia in an uninfected children cohort born to HIV-infected women. MATERIAL AND METHODS We followed up 623 uninfected children belonging to the FIPSE cohort according to standardised protocols. This cohort groups 8 hospitals from Madrid and follows up HIV infected pregnant women and their children. Anaemia and neutropenia were defined according to the ACTG (AIDS Clinical Trails Group) toxicity tables. Children were classified according to prematurity, ethnic origin, birth weight, withdrawal syndrome, in-utero treatment and neonatal prophylaxis. Categorical variables were compared with the chi2 or the Fisher tests. RESULTS Anaemia was observed in 188 (30.1%) children during follow-up and 161 (25.8%) had anaemia grade 2 or higher. Prematurity (p < 0.001), low birth weight (p = 0.005) and Highly Active Antiretroviral Treatment (HAART) with Protease Inhibitors (p = 0.016) were associated with higher percentages of anaemia in children. Nadir haemoglobin values were reached by 6 weeks of life and anaemia was transient and disappeared by six months of age. Neutropenia was present in 41.9% (261 children) and 22.7% of the children had moderate-severe neutropenia. Prematurity was again associated with neutropenia (p = 0.01) and low birth weigh was associated only with moderate-severe neutropenia (p = 0.023). African infants had a higher percentage of neutropenia than the rest of the children (50% vs. 44%), although the differences were not significant. The type of in-utero treatment did not appear to influence the neutropenia. Neutropenia was still present in 12.5% of infants at 18 months of age. The type of neonatal prophylaxis to prevent mother-to-child transmission (monotherapy, dual therapy or triple therapy) did not influence either cytopenia. CONCLUSION In our series, the proportion of children with anaemia is high: 30.1% Prematurity, low birth weight and HAART with IP were associated with a higher proportion of anaemia, which was transient and had little clinical relevance. The proportion of children with neutropenia was higher (41.9%) and was associated with prematurity, low birth weight and African origin. The type of neonatal prophylaxis does not seem to influence the development of cytopenias. Persistence of neutropenia (without clinical significance) was observed in a small percentage of the children 12.5%, at 18 months of age.

Abstract
INTRODUCTION Mother-to-Child HIV transmission is now just 1% in western countries, due to prevention measures. Antiretroviral Treatment (ART) drugs do have adverse effects, anaemia and myelosupression caused by cidovudina being the most commonly observed effects. In the present study, we have analysed the proportion and characteristics of congenital malformations (CM) or birth defects (BD) in a cohort of uninfected children born to HIV-infected women. METHODS A total of 623 uninfected children belonging to the FIPSE cohort were followed up according to standardised protocols. This cohort includes 8 public hospitals from Madrid and follows up HIV-infected pregnant women and their children. Children were classified according to prematurity, ethnic origin, birth weight, withdrawal syndrome, in-utero treatment. Birth defects were described and defined according to the EUROCAT, the European registry for BD. Mild errors of morphogenesis were excluded from the analysis. Categorical variables were compared with the X(2) or the Fisher test. RESULTS A total of 78% (486) of the mothers were of Caucasian origin; 18.8% (117) used some illicit drug (heroine, cocaine or methadone) during gestation; 51 mothers (8.1%) received no ART, 10 (1.6%) received monotherapy and 469 (75.3%) received HAART. BD were seen in 52 children, with the most frequent being genitourinary and cardiological. Anaemia in the first trimester was an associated risk for BD (17.9% vs. 8.1%, P = 0,04). Similarly, mothers who used any illicit drug (plus methadone), had a slightly higher risk for BD in their offspring (13.8% vs. 7.6%, P = 0,04) There was no increased risk for BD significantly associated with any of the in-utero used antiretrovirals, although Nevirapine use in-utero showed a protective effect. Children born to mothers who received ART in the first trimester had the same rate of BD (7.4%) as those whose mothers started ART in the second trimester (8.8%), P = 0,67. CONCLUSIONS The proportion of BD that we have observed seems higher than those shown in other European teratogenicity studies and also higher than those shown in cohorts with HIV and antiretroviral exposed infants. This may be due to the fact that our series show the results of an active surveillance system (that includes ultrasound), where BD classically appear in a higher proportion. Immunovirological characteristics of the mother did not influence the proportion of BD, but anaemia in the fist trimester and the use of illicit drugs (or methadone) did. No specific antiretroviral drug was associated with an increase in BD, although Nevirapine showed a possible protective effect in the statistical analysis. Mothers who started antiretrovirals in the first trimester do not have more BD in their offspring than mothers who started on antiretrovirals later on.

Abstract
BACKGROUND Bone metastases are common in lung cancer and are leading to increasing consumption of health care resources. The therapeutic choice for the clinician is extensive, from biphosphonates to percutaneous vertebroplasty. In the absence of official guidelines the management varies from centre to centre. There are very few economic analyses of these patients. METHODS Study 06-01 of the French Lung Oncology Group is a medico-economic analysis of the management of bone metastases in lung cancer. It is a national, multicentre, observational, epidemiological study. The primary objective is to assess the epidemiology, the management strategies and the costs of bone metastases in lung cancer. The secondary objective is to develop a medico-economic model of the management based on a Markov model in order to evaluate the effectiveness of different therapeutic strategies. EXPECTED RESULTS The aim of this study is a better understanding of theses patients at a time when few observational studies have been undertaken.

Abstract
A new controller based on a combination of Sliding Mode Control and Fuzzy Logic is proposed. The conventional sliding surface is modified using a set of fuzzy rules. This combination confers controller robustness and flexibility. A neutralization process and a mixing process are used to compare the performance of the new controller to that of a conventional sliding mode controller and a PID controller.

Abstract
INTRODUCTION The impact of chemotherapy-induced anemia on the quality of life (QOL) of patients with lung cancer has been little studied. OBJECTIVE We evaluated the feasibility of measuring QOL among patients receiving chemotherapy for lung cancer, and the possible correlation of QOL with the haemoglobin level. METHODS This was a prospective study of 53 patients starting chemotherapy (total 155 cycles); QOL was measured with the specific Fact-An scale. RESULTS The mean haemoglobin level before treatment was 13.1+/-2.3 g/dl. During chemotherapy 45.3% of patients received erythrocytic growth factors and 15.1% were transfused; 26.4% of patients refused to answer or could not answer the QOL questionnaire. There was a strong correlation between the Hb level and overall QOL (r=0.343, p=0.0004), as well as the physical and functional subscales (but not the cognitive and social subscales). CONCLUSIONS Although QOL could not be measured in one-quarter of cases, it was clearly affected by anaemia, which supports a strategy of early diagnosis and management of anaemia due to chemotherapy for lung cancer.

Abstract
There are estimated to be 350 million chronic carriers of hepatitis B infection worldwide. Patients with chronic hepatitis B are at risk of liver cirrhosis with associated mortality because of hepatocellular carcinoma and other complications. An important goal, therefore, is the development of an effective therapeutic vaccine against chronic hepatitis B virus (HBV). A major barrier to the development of such a vaccine is the impaired immune response to HBV antigens observed in the T cells of affected patients. One strategy to overcome these barriers is to activate mucosal T cells through the use of nasal vaccination because this may overcome the systemic immune downregulation that results from HBV infection. In addition, it may be beneficial to present additional HBV epitopes beyond those contained in the traditional hepatitis B surface antigen (HbsAg) vaccine, for example, by using the hepatitis B core antigen (HBcAg). This is advantageous because HBcAg has a unique ability to act as a potent Th1 adjuvant to HbsAg, while also serving as an immunogenic target. In this study we describe the effect of coadministration of HBsAg and HBcAg as part of a strategy to develop a more potent and effective HBV therapeutic vaccine.
