Abstract
BACKGROUND Routine prophylactic abdominal drains after laparoscopic appendectomy for perforated appendicitis in children are still controversial. Throughout the history of surgery, potential benefits of the abdominal drains have been described. However, in recent studies, no benefits were observed and serious complications have been reported. METHODS From January 2000 to December 2013, all charts of the pediatric patients who underwent laparoscopic appendectomy in our tertiary center were revised. The data from 1736 appendectomies were analyzed. We only included those patients with perforated appendicitis treated with early appendectomy (n = 192). Prophylactic drains were established according to the surgeon's preference. The sample was divided into two groups, those with drain (n = 117) and those without drain (n = 75). Demographics, operative findings, and postoperative outcomes were analyzed in both groups. RESULTS Of all patients, 121 were male and 71 were female with a mean age of 7.77 ± 3.4 years. There were not statistically significant differences between the groups in gender (p = 0.82) and mean age (p = 0.31). There were no statistically significant differences between the two groups in the rate of intra-abdominal abscess, wound infection, and bowel obstruction. However, the drainage group has been statistically associated with an increased requirement of antibiotic and analgesic medication, fasting time, operative time, and length of hospital stay. CONCLUSION The prophylactic use of abdominal drainage after laparoscopic appendectomy for perforated appendicitis in children does not prevent postoperative complications and may be associated with negative outcomes. Prospective randomized studies will be necessary to verify this question.

Abstract
Pt NPs covered with zwitterionic amidinates as ligands exhibit an exciting ligand effect in the hydrogenation of carbonyl groups when electron donor/acceptor groups are introduced in the N-substituents.
Ligand control of metal nanoparticles (MNPs) is rapidly gaining importance as ligands can stabilize the MNPs and regulate their catalytic properties. Herein we report the first example of Pt NPs ligated by imidazolium-amidinate ligands that bind strongly through the amidinate anion to the platinum surface atoms. The binding was established by 15N NMR spectroscopy, a precedent for nitrogen ligands on MNPs, and XPS. Both monodentate and bidentate coordination modes were found. DFT showed a high bonding energy of up to –48 kcal mol–1 for bidentate bonding to two adjacent metal atoms, which decreased to –28 ± 4 kcal mol–1 for monodentate bonding in the absence of impediments by other ligands. While the surface is densely covered with ligands, both IR and 13C MAS NMR spectra proved the adsorption of CO on the surface and thus the availability of sites for catalysis. A particle size dependent Knight shift was observed in the 13C MAS NMR spectra for the atoms that coordinate to the surface, but for small particles, ∼1.2 nm, it almost vanished, as theory for MNPs predicts; this had not been experimentally verified before. The Pt NPs were found to be catalysts for the hydrogenation of ketones and a notable ligand effect was observed in the hydrogenation of electron-poor carbonyl groups. The catalytic activity is influenced by remote electron donor/acceptor groups introduced in the aryl-N-substituents of the amidinates; p-anisyl groups on the ligand gave catalysts several times faster the ligand containing p-chlorophenyl groups.

Abstract
OBJECTIVE This study sought to evaluate the long-term osteosynthesis results for AO/OTA 31.A1-A2 pertrochanteric fractures treated with the percutaneous compression plate (PCCP). MATERIALS AND METHODS This investigation was a retrospective observational descriptive study of 335 patients, with a minimum follow-up of 2 years and a maximum follow-up of 8 years (2004-2011). RESULTS The average post-operative hospital stay was 6.2 days, and the average decrease in haemoglobin levels after the intervention was 2.7 mg/dL, with transfusion required for one-third of the patients. Complications related to the implant were observed in 4.2 % of patients; the most notable complication was cut-out (2.4 % of patients), and 3 cases involved pseudarthrosis with breakage of the implant (0.9 % of patients). CONCLUSIONS From the results obtained in this study and an analysis of previously published work, we believe that the PCCP may be the implant of choice for AO/OTA 31.A1-A2 fractures.

Abstract
Studies that analyze the epidemiology and risk factors for invasive fungal disease (IFD) after engraftment in alloSCT are few in number. This single-center retrospective study included 404 alloSCT adult recipients surviving >40 days who engrafted and were discharged without prior IFD. All patients who received ⩾20 mg/day of prednisone were assigned to primary oral prophylaxis (itraconazole or low-dose voriconazole). The primary end point was the cumulative incidence (CI) of probable/proven IFD using the European Organization for Research and Treatment of Cancer and Mycoses Study Group (EORTC/MSG) criteria. The independent prognostic factors after multivariate analyses were used to construct a post-engraftment IFD risk score. The 1-year CI of IFD was 11%. The non-relapse mortality was 40% in those developing IFD and 16% in those who did not. The intent-to-treat analysis showed that 17% of patients abandoned the assigned prophylaxis. Age >40 years, ⩾1 previous SCT, pre-engraftment neutropenia >15 days, extensive chronic GVHD and CMV reactivation were independent risk factors. The post-engraftment IFD score stratified patients into low risk (0-1 factor, CI 0.7%), intermediate risk (2 factors, CI 9.9%) and high risk (3-5 factors, CI 24.7%) (P<0.0001). The antifungal prophylaxis strategy failed to prevent post-engraftment IFD in 11% of alloSCT. Our risk score could be useful to implement risk-adapted strategies using antifungal prophylaxis after engraftment.

Abstract
KEY POINTS We expanded a prior model of whole-body O2 transport and utilization based on diffusive O2 exchange in the lungs and tissues to additionally allow for both lung ventilation-perfusion and tissue metabolism-perfusion heterogeneities, in order to estimate V̇O2 and mitochondrial PO2 (PmO2) during maximal exercise. Simulations were performed using data from (a) healthy fit subjects exercising at sea level and at altitudes up to the equivalent of Mount Everest and (b) patients with mild and severe chronic obstructive pulmonary disease (COPD) exercising at sea level. Heterogeneity in skeletal muscle may affect maximal O2 availability more than heterogeneity in lung, especially if mitochondrial metabolic capacity (V̇ MAX ) is only slightly higher than the potential to deliver O2 , but when V̇ MAX is substantially higher than O2 delivery, the effect of muscle heterogeneity is comparable to that of lung heterogeneity. Skeletal muscle heterogeneity may result in a wide range of potential mitochondrial PO 2 values, a range that becomes narrower as V̇ MAX increases; in regions with a low ratio of metabolic capacity to blood flow, PmO2 can exceed that of mixed muscle venous blood. The combined effects of lung and peripheral heterogeneities on the resistance to O2 flow in health decreases with altitude. ABSTRACT Previous models of O2 transport and utilization in health considered diffusive exchange of O2 in lung and muscle, but, reasonably, neglected functional heterogeneities in these tissues. However, in disease, disregarding such heterogeneities would not be justified. Here, pulmonary ventilation-perfusion and skeletal muscle metabolism-perfusion mismatching were added to a prior model of only diffusive exchange. Previously ignored O2 exchange in non-exercising tissues was also included. We simulated maximal exercise in (a) healthy subjects at sea level and altitude, and (b) COPD patients at sea level, to assess the separate and combined effects of pulmonary and peripheral functional heterogeneities on overall muscle O2 uptake (V̇O2) and on mitochondrial PO2 (PmO2). In healthy subjects at maximal exercise, the combined effects of pulmonary and peripheral heterogeneities reduced arterial PO2 (PaO2) at sea level by 32 mmHg, but muscle V̇O2 by only 122 ml min(-1) (-3.5%). At the altitude of Mt Everest, lung and tissue heterogeneity together reduced PaO2 by less than 1 mmHg and V̇O2 by 32 ml min(-1) (-2.4%). Skeletal muscle heterogeneity led to a wide range of potential PmO2 among muscle regions, a range that becomes narrower asV̇ MAX increases, and in regions with a low ratio of metabolic capacity to blood flow, PmO2 can exceed that of mixed muscle venous blood. For patients with severe COPD, peak V̇O2 was insensitive to substantial changes in the mitochondrial characteristics for O2 consumption or the extent of muscle heterogeneity. This integrative computational model of O2 transport and utilization offers the potential for estimating profiles of PmO2 both in health and in diseases such as COPD if the extent for both lung ventilation-perfusion and tissue metabolism-perfusion heterogeneity is known.

Abstract
A challenge model for pancreas disease in Atlantic salmon, Salmo salar L. fry, was developed comparing two salmonid alphavirus (SAV) subtypes: SAV1 and SAV5. Viral doses of 3 × 10(5) TCID50 mL(-1) for SAV1 and 3 × 10(4) for SAV5 were tested in triplicate tanks, each containing 450 salmon fry. Cumulative mortalities of 1.2% were recorded. Titres of virus recovered from the mortalities ranged from 10(2) to 10(7) TCID50 mL(-1) . Fry were sampled at 3, 5 and 7.5 weeks post-challenge. Sampling after 3 weeks revealed a high prevalence of infection in the absence of clinical signs, and infectious virus was recovered from 80% and 43% of sampled fry infected with SAV1 and SAV5, respectively. After 5 weeks pancreas, heart and red skeletal muscle lesions were generally observed, whilst degeneration in white skeletal muscle was observed only in fish infected with SAV1. In situ hybridisation confirmed the presence of viral genome in infected pancreas, heart and muscle. After 7.5 weeks, infectious virus (both isolates) was recovered from 13.3% of the fish sampled, with a viral titre of 10(2) TCID50 mL(-1) . Clearly, salmon fry are susceptible to SAV infection and pancreas disease.

Abstract
In previous calculations of how the O2 transport system limits .VO2(max), it was reasonably assumed that mitochondrial P(O2) (Pm(O2)) could be neglected (set to zero). However, in reality, Pm(O2) must exceed zero and the red cell to mitochondrion diffusion gradient may therefore be reduced, impairing diffusive transport of O2 and .VO2(max). Accordingly, we investigated the influence of Pm(O2) on these calculations by coupling previously used equations for O2 transport to one for mitochondrial respiration relating mitochondrial .VO2 to P(O2). This hyperbolic function, characterized by its P50 and V˙MAX, allowed Pm(O2) to become a model output (rather than set to zero as previously). Simulations using data from exercising normal subjects showed that at .VO2(max), Pm(O2) was usually <1mmHg, and that the effects on .VO2(max) were minimal. However, when O2 transport capacity exceeded mitochondrial V˙MAX, or if P50 were elevated,Pm(O2) often reached double digit values, thereby reducing the diffusion gradient and significantly decreasing .VO2(max).

Abstract
The transmission of lymphocystis disease virus (LCDV) to gilthead seabream, Sparus aurata L., larvae was investigated using fertilized eggs from a farm with previous reports of lymphocystis disease. LCDV genome was detected by PCR-hybridization in blood samples from 17.5% of the asymptomatic gilthead seabream broodstock analysed. Using the same methodology, eggs spawned from these animals were LCDV positive, as well as larvae hatched from them. The presence of infective viral particles was confirmed by cytopathic effects development on SAF-1 cells. Whole-mount in situ hybridization (ISH) and immunohistochemistry (IHC) showed the presence of LCDV in the epidermis of larvae hatched from LCDV-positive eggs. When fertilized eggs were disinfected with iodine, no viral DNA was detected either in eggs (analysed by PCR-hybridization) or in larvae (PCR-hybridization and ISH). These results suggest the vertical transmission of LCDV, the virus being transmitted on the egg surface. Larvae hatched from disinfected eggs remain LCDV negative during the endotrophic phase, as showed by PCR-hybridization, ISH and IHC. After feeding on LCDV-positive rotifers, viral antigens were observed in the digestive tract, which suggests that viral entry could be achieved via the alimentary canal, and that rotifers can act as a vector in LCDV transmission to gilthead seabream larvae.

Abstract
INTRODUCTION Minimally Invasive Surgery (MIS) is getting more and more important in our specialty. However, the formation of the residents on MIS is, in many cases, irregular. The purpose of this study is to assess the state of training in MIS among the residents of Pediatric Surgery and their potential weaknesses. MATERIAL AND METHODS An electronic survey was distributed among 71 residents of Pediatric Surgery from 17 national hospitals. RESULTS The response rate was 70.2%.100% of the residents are interested in a broadening of training activities in MIS. The main areas of interest are gastrointestinal (92%) and thoracic (47%) surgery. Only 57% have access to training facilities and less than half of them attend to courses and conferences. 80% believe that they are not given adequate attention from specialized associations. 52% think they should do rotations at referral centers, 86% that courses and seminars should be enhanced, and 44% that the responsibility of the resident in surgery should be increased. The main defects encountered in their training are scarce volume of patients, lack of financial support and overcoming the learning curve of surgeons in their services. CONCLUSIONS Despite the advance of the MIS, resident's training in this discipline still has shortcomings, as expressed in their views. Knowledge of the current state of training should be the starting point for designing a training strategy that ensures adequate skills.

Abstract
The pneumoperitoneum induced during laparoscopy has cardiovascular and respiratory effects that have to be taken into account to perform laparoscopic procedures in neonates and small infants. The aim of this paper is to describe the hemodynamic and ventilatory changes that occur in a group of these patients undergoing standard laparoscopic procedure. We performed a retrospective review of patients undergoing laparoscopic pyloromyotomy in our institution. We collected demographic data, data from the intervention, outcome and complications and hemodynamic parameters (heart rate--HR--and blood pressure--BP--) and respiratory (O2 saturation--SO2--and exhaled CO2--ECO2--) at different times during surgery. We performed statistical analysis of these data. We reviewed a total of 55 charts. Mean age was 34 days and average weight 3,785 g. All patients were ventilated with pressure control mode and received maintenance fluid therapy. BP, HR and SO2 were stable throughout the surgery not showing significant differences. The ECO2 increased significantly after inflation, however it was controlled by increasig respiratory rate. In conclusion, the hemodynamic and ventilatory response in these patients is controllable with anesthetic and surgical measures but it is important to consider the possible consequences of pneumoperitoneum in this group of patients.

Abstract
A simple and low cost method for wavelength control of economical random non-preselected independent ONU sources is shown to increase the number of users in an OFDMA-PON. The method is based on OLT monitoring and thermal tuning control; it has been validated through Monte-Carlo simulations and a probabilistic model. The minimum optical spectral gap between the ONUs wavelengths that guarantees a tolerable amount of optical beat interference has been determined through an experiment.

Abstract
INTRODUCTION Pectus carinatum (PC) is a deformity that involves the protrusion of the anterior chest wall. It is 10 times less frequent than pectus excavatum. It has a progressive growth and is more common with men. There are two different types, the lower or condrocorporal which is the most common one, and the upper or condromanubrial. Most of the time there are no cardio-respiratory symptoms. OBJECTIVE We present our experience in the orthopedic treatment of the pectus carinatum. METHOD Retrospective review of patients treated in our hospital from 2002 until 2009. Patients were treated with observation, aerobic exercises, postural change and/or compression braces. Literature review was performed of the treatment for this pathology. RESULTS 18 patients have been diagnosed with PC, 16 were men and 2 women. All were treated in a nonoperative way. Only 11 of them used a compression brace. We missed two follow-ups and another has just yet begun to achieve proper results. All the rest have had excellent results with nonoperative treatment. None of them have had a surgical treatment. CONCLUSION The PC is a disease that most often is a cosmetic problem, with no impact on a cardio-respiratory level. Classically it has been a surgical entity. In our experience we have found that the orthopedic method is an effective alternative, safe and with a significant reduction in morbidity. But we need the collaboration of the patient to accept and maintain continuity in the use of the prostheses.

Abstract
The management of blunt abdominal traumatism with a moderate amount of free peritoneal fluid and without solid organ injury as well as the one of minimal penetrating trauma is controversial. We present three cases of blunt abdominal trauma and two of penetrating trauma that underwent diagnostic laparoscopy in our department. We found a small bowel perforation in one of the cases of blunt trauma that was repaired by externalization of the jejuna loop by one of the ports. In the other two cases we found intestinal and mesenteric contusions and free fluid that were treated by peritoneal drainage. One of the cases of penetrating trauma presented omentum evisceration with no other injuries and the second presented a gastric perforation that needed reconversion to laparotomy. In our experience and according to literature, laparoscopy should be taken into account as a diagnostic procedure and sometimes also therapeutic in selected cases of both blunt and penetrating abdominal trauma in pediatric population.

Abstract
Gilthead seabream (Sparus aurata) and European seabass (Dicentrarchus labrax) were subjected to either experimental infection with Photobacterium damselae subsp. piscicida or Nodavirus after a period of 2 weeks of crowding in which fish were subjected to a 5-fold increase in density (10-50 kg/m(3)). Samples were obtained before the crowding period (0 h or control) and at 24h and 72 h after crowding from both groups of infected fish. The Complement haemolytic activity and the expression of the C3 gene were evaluated in blood and liver samples respectively. The bacteriolytic and lysozyme activities were also assessed. The results showed that Complement haemolytic activity was reduced at 72 h with both bacteria and virus in high density Gilthead seabream, and a similar increase was observed at low density. Bacteriolytic activity under both bacterial and viral challenges for both species was increased at 24h, under low density. At high density, the bacterial challenge did not induce significant changes. C3 mRNA abundance was substantially increased after pathogen treatments in low density groups at 24h but no significant changes were detected at high densities. These results support the idea of the suppressor effect of stressors on the immune system since a reduction of Complement activity under virus and high density, or lack of response in C3 expression under high density were observed.

Abstract
The use of laparoscopy in patients with ventriculo-peritoneal shunts has been controversial. There is concern about the risk malfunction or infection of the shunt as well as about the possibility of adhesions that could make the surgical procedures too difficult to be undertaken by minimally invasive surgery. We present our results in pediatric patients with ventriculoperitoneal shunts that have undergone laparoscopic procedures in our department. We have performed 16 surgical procedures. The most frequent indication was fundoplication. During surgery there were no complications or intracranial hypertension episodes. Two of the procedures were considered by the surgeons more difficult and longer than usual. None of them required conversion to open technique. One shunt had to be replaced after surgery because of infection. According to our experience minimally invasive surgery is feasible and safe in pediatric patients with ventriculo-peritoneal shunts.

Abstract
AIMS To detect the possible coexistence of striped jack nervous necrosis virus (SJNNV) and red-spotted grouper nervous necrosis virus (RGNNV) genotypes in a single fish, a methodology based on the combination of PCR amplification and blot hybridization has been developed and applied in this study. METHODS AND RESULTS The degenerate primers designed for the PCR procedure target the T4 region within the capsid gene, resulting in the amplification of both genotypes. The subsequent hybridization of these amplification products with two different specific digoxigenin-labelled probes resulted in the identification of both genotypes separately. The application of the RT-PCR protocol to analyse blood samples from asymptomatic wild meagre (Argyrosomus regius) specimens has shown a 46.87% of viral nervous necrosis virus carriers. The combination of RT-PCR and blot hybridization increases the detection rate up to 90.62%, and, in addition, it has shown the coexistence of both genotypes in 18 out of the 32 specimens analysed (56.25%). CONCLUSIONS This study reports the coexistence of betanodaviruses belonging to two different genotypes (SJNNV and RGNNV) in wild fish specimens. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first report demonstrating the presence of SJNNV and RGNNV genotypes in the same specimen. This study also demonstrates a carrier state in this fish species for the first time.

Abstract
INTRODUCTION The inguinal hernia surgery is common in the pediatric population although laparoscopic management today, is not considered the standard technique. The aim of this study is to review the results of our study and evaluate the contralateral side in patients with unilateral hernia. MATERIAL AND METHODS Retrospective study of laparoscopic herniorraphy at our hospital since the beginning of the art in 1999 with a total of 348 patients. The indications of laparoscopy have been the availability of umbilical hernia associated, doubt diagnosis, recurrence of open surgery, bilateral tumor and casual diagnosis. We analyzed the following parameters: sex, age, weight, associated diagnosis, intra and postoperative complications, recurrence and follow-up. RESULTS 474 hernias were repaired laparoscopically in 348 patients. A predominance of males against females (30%). In 37 patients (11%) the diagnosis was made during another operation. 39 patients with recidive open surgery were operated by laparoscopy. We had only 2% intraoperative complications and 2% of recurrences. The follow-up period is 10 years. CONCLUSIONS Laparoscopic herniorraphy may be a routine procedure with results comparable to open surgery. Laparoscopy offers a good overview of the anatomy, easily identifying the defect, with a technique increasingly used in the field of pediatric surgery.

Abstract
A non-destructive procedure based on nested RT-PCR and dot-blot hybridization has been developed for the detection of asymptomatic IPNV-carrier fish. The pair of primers designed for RT-PCR amplified a 599-bp fragment of the pVP2 region within the polyprotein gene, resulting in the detection of IPNV genotype III.1. The use of a nested RT-PCR allowed the amplification of IPNV genotypes III.1 and I.2. In addition, a 191-bp probe was designed for hybridization studies used in combination with the nested RT-PCR. The application of the nested RT-PCR to analyse blood samples from asymptomatic redbanded seabream, Pagrus auriga, and common seabream, P. pagrus, specimens showed a 53.1% and 77.8% prevalence of IPNV-carriers, respectively. The combination of nested RT-PCR and dot-blot hybridization increased the detection rates up to 100% for redbanded seabream and 94.4% for common seabream. Therefore, the protocol described in this study is highly sensitive and specific for the detection of IPNV in asymptomatic carrier fish, and, in addition, the results demonstrate the carrier state in two newly cultured sparid species in southern Spain.

Abstract
Naïve sea bass juveniles (38.4 + or - 4.5 g) were intramuscularly infected with a sublethal dose of betanodavirus isolate 378/I03, followed after 43 days by a similar boosting. This infection resulted in an overall mortality of 7.6%. At various intervals, sampling of fish tissues was performed to investigate: i) B and T lymphocyte content in organs and tissues; ii), proliferation of leucocytes re-stimulated in vitro with inactivated virus; iii) presence of serum antibody specific for betanodavirus; iv) expression of genes coding for the following immunoregulatory molecules involved in innate and acquired responses: type I IFN, Mx, IL-1, Cox-2; IL-10, TGF-beta, TCRbeta, CD4, CD8alpha, IgM, by using a quantitative PCR array system developed for sea bass. The obtained results showed a detectable increase of T cells and B cells in PBL during betanodavirus infection. Furthermore, leucocytes obtained from blood, head kidney, and gills showed a detectable "in vitro" increase in viability upon addition of inactivated viral particles, as determined by measuring intracellular ATP concentration. ELISA analysis of sera showed that exposure to nodavirus induced a low, but specific antibody titer measured 43 days after infection, despite the presence of measurable levels of natural antibody. Finally, a strong upregulation of genes coding for type I IFN, Mx, and IgM was identified after both infection and boosting. Interestingly, an upregulation of Cox-2 until boosting, and of TGF-beta and IL-10 after boosting was also observed, while the other tested genes did not show any significant variations with respect to mock-treated fish. Overall, our work represents a first comprehensive analysis of cellular and molecular immune parameters in a fish species exposed to a pathogenic virus.

Abstract
Immunohistochemistry (IHC) and in situ hybridization (ISH) techniques have been used for the detection of lymphocystis disease virus (LCDV) in formalin-fixed, paraffin-embedded tissues from gilt-head seabream, Sparus aurata L. Diseased and recovered fish from the same population were analysed. IHC was performed with a polyclonal antibody against a 60-kDa viral protein. A specific digoxigenin-labelled probe, obtained by PCR amplification of a 270-bp fragment of the gene coding the LCDV major capsid protein, was used for ISH. LCDV was detected in skin dermis and gill lamellae, as well as in several internal organs such as the intestine, liver, spleen and kidney using both techniques. Fibroblasts, hepatocytes and macrophages seem to be target cells for virus replication. The presence of lymphocystis cells in the dermis of the skin and caudal fin, and necrotic changes in the epithelium of proximal renal tubules were the only histological alterations observed in fish showing signs of the disease.

Abstract
The investigation of a male with impalpable testes is one of the most frequent diagnostic indications of laparoscopy and it is accepted as a therapeutic tool for the treatment of the intra-abdominal testis. We have studied thirteen patients being surgically operated by a video-assisted orchidopexy without spermatic vessels section. The technique consists of wide mobilization of the spermatic vessels and the vas deferens from the posterior peritoneum, sectioning the gubernaculum and descending of the testis to the scrotum. In all the cases, the internal groin ring was later closed by means of a laparoscopy. There were no intraoperative complications. In 100% of the cases, the testis was descended to the scrotum. The surgical time oscillated between 40 and 80 minutes (60 minutes mean). At follow-up from 6 months to 4 years, the outcome was satisfactory in 11 patients, whereas in 2 cases the operated testis ascended.

Abstract
AIMS The development and evaluation of a protocol based on polymerase chain reaction (PCR) and nucleic acid hybridization techniques for the specific detection of lymphocystis disease virus (LCDV) in several marine fish species. METHODS AND RESULTS The pair of primers for PCR, OBL3 and OBL4, was designed based on published nucleotide sequence (LCDV-1) and amplifies a fragment within the major capsid protein. The sensitivity was evaluated using DNA from purified viral particles, as well as from cells inoculated with several viral concentrations. The PCR combined with slot blot was the most sensitive methodology, detecting 2.5 ng of viral DNA. Using this methodology LCDV was detected at 5 days postinoculation from SAF-1 cells initially inoculated with 10(-5) TCID(50) ml(-1). The combination of PCR with membrane hybridization has also been proved to be adequate to detect LCDV from apparently healthy carriers by means of caudal fin sample analysis. This asymptomatic infection was also demonstrated by classical virological methods (cell culture and immunoblot). CONCLUSIONS The protocol described in this study allows the specific detection of LCDV, both in cell cultures and in fin homogenates from asymptomatic fish. SIGNIFICANCE AND IMPACT OF THE STUDY The detection of asymptomatic carriers by a rapid molecular method using caudal fin sampling, which does not imply animal killing, could be an important tool to control epizootics caused by LCDV, as fish could be analysed before their introduction and/or mobilization in farm facilities.

Abstract
The proportion of recurrent tuberculosis (TB) cases caused by re-infection has varied widely in previous studies. The aim of the present study was to determine the relative frequency of relapse and exogenous re-infection in patients with second episodes of TB, using DNA fingerprinting. A population-based retrospective longitudinal descriptive study was conducted in Madrid (Spain) during 1992-2004. The study consisted of 645 patients with culture-confirmed TB. Of these, 20 (3.1%) were retained because they presented with a second isolate of Mycobacterium tuberculosis. Finally, 12 of these cases were excluded because they did not complete the full treatment prescribed. All strains were typed by restriction fragment length polymorphism analysis and some by mycobacterial interspersed repetitive unit-variable number of tandem repeats analysis. The patients with recurrent TB were compared with those without recurrent TB. For seven out of the eight patients, the restriction fragment length polymorphism patterns of the Mycobacterium tuberculosis strains from the episodes of recurrent disease showed identical initial and final genotypes, indicating relapse; the remaining recurrent case showed different genotypes, suggesting exogenous re-infection. Re-infection is possible among people in developed countries, but the rates are lower than those occurring in high-risk areas. The risk factors for recurrent tuberculosis should be taken into account in the follow-up of treatment and tuberculosis control strategies.

Abstract
The onset and development of symptoms of three Sambucus species, S. ebulus, S. nigra and S. racemosa were studied in 2002 under three different experimental conditions, in charcoal filtered air (CF), and in two ozone enriched treatment: non filtered air plus 40 ppb ozone (NF+), and non filtered air plus 70 ppb ozone (NF++). The herb S. ebulus was more sensitive than the shrubs S. racemosa and S. nigra. Some plants of the three species showed visible injury below the AOT40 threshold of 10,000 ppb.h, established for protection of vegetation. Ozone produced a decrease in chlorophyll content in S. ebulus, and impaired both stomatal conductance and net photosynthesis in S. ebulus and S. nigra. A complementary study in 2004 with S. ebulus, confirmed a decrease in chlorophyll content after fumigation, associated to a decrease in N content of the leaves. Since S. ebulus is a widespread species in Europe and it is very sensitive to ozone, it could be a very appropriate plant for the biomonitoring studies across large areas in this continent.

Abstract
INTRODUCTION Clinical nutrition is an activity realized in most of Health Centres of France, Canada, Great Britain and USA. The aim of our work was to determine activity and resources of Nutrition Units of Hospitals in the Community of Castilla y León. MATERIAL AND METHODS A questionnaire was send to all Hospitals of Castilla y León (SACYL); Hospital Universitario Rio Hortega, Hospital Clinico Universitario, Hospital Comarcal de Medina del Campo, Hospital General Yagüe-Divino Vallés (Burgos), Complejo Hospitalario de Le6n, Hospital General de Segovia, Hospital Virgen de Sonsoles de Avila, Hospital Virgen de la Concha de Zamora, Hospital Comarcal de Aranda de Duero, Hospital Comarcal de Miranda, Hospital General de Soria, Hospital Clinico Universitario de Salamanca. RESULTS Nine Centres responded questionnaire (75%). A total of 5 Hospitals had a Unit of Nutrition (55.6%). The results showed an average of 0.37 +/- 0.55 specialists for each 400 beds, 0.87 +/- 0.63 nurses for each 400 beds and 1.91 +/- 2.3 auxiliaries for each 400 beds, with an average of 0.21 +/- 0.41 specialists for each 100,000 habitants, 0.49 +/- 0.36 nurses for each 100,000 habitants and 1.09 +/- 1.2 auxiliaries for each 100,000 habitants. The activity of these Units is demanded by other Units, with an average of 3.2 +/- 3.4 consultations per day. The main diseases of this activity were 33.3% tumoral pathology, 55.6% surgery and 11.1% neurological pathology. Oral supplements were the first intervention tool. Only 3 Centres had a home artificial nutrition consultation. The main diseases of this activity were post surgical patients (33,3%), tumoral pathology (33,3%), neurological pathology (22%) and inflammatory bowel disease (11%). CONCLUSION Resources in Units of Nutrition of Castilla y Leon were limited. However, activity in Hospital an in home is equal than other areas. New actions of Local Administration are necessaries to follow recommendations of Council of Europe.

Abstract
INTRODUCTION Congenital tracheomalacia (CTM) is a rare disease causing tracheal wall collapse when breathing. Herein, we show our experience in the management of this type of airway anomaly, settling the indications for surgical or endoscopic treatment. PATIENTS AND METHODS We have performed a retrospective study, from 1991 to 2003, of patients with a bronchoscopic diagnosis of CTM or bronchomalacia (BM). We have analyzed the following facts: sex, age, indication of the initial bronchoscopy, ethiology, clinical group, anatomic type, associated malformations, treatment modality, complications, results, and time of follow-up. RESULTS 46 patients have been included in this study: 25 boys (54%) and 21 girls (45%). Mean age at diagnosis has been 11 months. The indications for diagnostic bronchoscopy have been: respiratory distress (24%), lung athelectasia (24%), stridor (21%), congenital tracheoesophageal fistula (11%), extubation failure (11%), apneic spells (6%), and recurrent pneumonia (2%). Secondary CTM has been much more frequent (82%) than the primary type (17%). Patients have been classified into 3 groups according to the severity of symptoms: group I--mild symptoms (7 patients); group II---moderate (22); and group III, severe (17). Tracheomalacia was diagnosed in 26 cases (56%), bronchomalacia in 12 (26%) and tracheobronchomalacia in 8 patients (17%). Almost all the patients (95%) have showed other associated malformations. Medical treatment has been instituted in 29 patients (63%), 15 cases (32%) have been managed surgically or endoscopically, and in 2 cases no treatment was tried because of their critical clinical status. In addition, in 17 patients (37%) an antireflux surgical procedure was performed. Satisfactory results have been achieved in 72% of treated patients, fair results were obtained in 4 (9%), and a poor outcome occurred in 2 (4,5%). Another 8 patients have died during follow-up due to unrelated causes. 36 patients (78%) are alive with a mean follow-up period of 5,3 years. CONCLUSIONS Most patients with CTM can he treated conservatively though spontaneous resolution may he expected after the first year of life. Surgical or endoscopical procedures are indicated in those patients with severe respiratory symptoms.

Abstract
An immunoblot technique for the detection of lymphocystis disease virus (LCDV) in naturally infected gilt-head seabream (Sparus aurata, L.) has been developed. A specific antiserum against a 60 kDa viral protein has been proven to be an appropriate tool for LCDV diagnosis either from inoculated cell cultures or from fish tissues using the immunoblot assay. The sensitivity of this technique varied between 10(-1) and 10(2) TCID50. LCDV has also been detected in fish tissues from both, diseased and asymptomatic gilt-head seabream. For the asymptomatic fish detection, a viral amplification step in cell culture and a subsequent viral concentration using polyethylene glycol (PEG) (600 wt) are required. On the contrary, immunoblot allowed the detection of LCDV antigens directly from tissue homogenates of diseased fish. The method described in this study shows higher sensitivity than classical detection techniques based on cell culture inoculation.

Abstract
We describe a continuous flow mode of ventilation for repair of type I esophageal atresia in an infant. This type of atresia is defined by distal stenosis of the esophagus with a proximal blind pouch and no connection to the tracheobronchial tree. In traditional repair procedures the surgical approach is by thoracotomy, but newer videoassisted thoracoscopic techniques have introduced novel challenges to ventilatory mechanics in these low-weight infants. The literature contains little discussion of the anesthetic management or respiratory mechanics of these patients. Trying to maintain adequate tidal volume and oxygenation while thoracoscopic maneuvers take place increases the risk of barotrauma. Single-lung ventilation with a continuous flow respirator was effective in the case we report.

Abstract
Two viruses were isolated from cultured sole, Solea senegalensis, and wild blackspot sea bream, Pagellus bogaraveo, and preliminarily characterized as lymphocystis disease viruses (LCDVs). Viral isolates were characterized by morphological, biochemical and biophysical properties. In addition, the susceptibility of four fish cell lines was also tested. LCDV isolates developed cytopathic effects on the SAF-1 cell line at 5 and 6 days post-infection and reached titres of 10(6) TCID50 mL(-1). The antigenic and structural protein analysis of the two new LCDV isolates showed identical profiles to that obtained for LCDV strain Leetown NFH (ATCC VR-342), used as a reference viral strain, and for an LCDV isolate collected from gilt-head sea bream, Sparus aurata, cultured in southern Spain. Molecular confirmation was performed by polymerase chain reaction. Specific primers for LCDV produced a 270-bp DNA fragment, the expected size for LCDV.

Abstract
An in situ hybridisation (ISH) technique has been developed to detect sole aquabirnavirus in infected fish cell lines bluegill fibroblast (BF-2), EPC, and chinook salmon embryo cells (CHSE-214). A 613 bp cDNA probe for viral RNA coding for a fragment of VP2 protein was generated by reverse transcription polymerase chain reaction (RT-PCR) using infectious pancreatic necrosis virus (IPNV) specific DNA primers. Infected cells were strongly labelled, and no non-specific reaction was observed in non-infected cells used as negative controls. The specificity of the probe was examined by testing it against a range of IPNV serotypes such as Ab, Sp and VR-299. The ISH technique was compared with the immunofluorescence procedure to determine the sensitivity of detection of sole aquabirnavirus in BF-2 cells. The probe used in the ISH technique detected weak positivity at 8h post-inoculation (p.i.) in the cytoplasm of infected BF-2 cells inoculated with 10(3) TCID50/ml, whilst the labelling appears at 24h p.i. when the immunofluorescence technique was applied. At all other time intervals the results were equivalent.

Abstract
A 1-year-old girl presented with fever, asthenia, and splenomegaly with hypersplenism. Abdominal ultrasound scan and magnetic resonance imaging showed multiple nodular cystic masses in an enlarged spleen. The histological examination of the resected spleen showed a novel type of vascular tumor called littoral cell angioma. The histopathologic and immunohistochemical features of this rare lesion are described. Distinction from other splenic vascular tumors is stressed because the clinical behavior of this new entity seems to be benign.

Abstract
We present here a characterization of the telomeric and subtelomeric regions of Trypanosoma cruzi chromosomes, using three types of recombinants: cosmids from a genomic library, clones obtained by a vector-adaptor protocol, and a recombinant fragment cloned by a Bal31 trimming protocol. The last nine nucleotides of the T. cruzi overhang are 5'-GGGTTAGGG-3', and there are from 9 to 50 copies of the hexameric repeat 5'-TTAGGG-3', followed by a 189-bp junction sequence common to all recombinants. The subtelomeric region is made of sequences associated with the gp85/sialidase gene family, and/or sequences derived from SIRE, a retrotransposon-like sequence, and also the retrotransposon L1Tc. We discuss the possible implications of this genome organization.

Abstract
OBJECTIVE The objective of this study was to determine the incidence of surgical wound infection and the impact of this on the implementation of an antibiotic protocol according to the type of surgery and the prevailing endogenous flora in our neonatology unit. PATIENTS AND METHODS Patients' charts were retrospectively reviewed in order to assess the effectiveness of a protocol of surgical prophylaxis, comparing the incidence of postsurgical wound infection in two periods of time. Surgical interventions were classified according to the period of the study in which they were performed, before (period A) and after (period B) the protocol was undertaken. In addition, if the antibiotics administered fit or not those indicated in the protocol, it was classified as correct or not. RESULTS A total of 31 (37%) of the interventions were performed in period A, whereas 53 (63%) were carried out in period B. No statistically significant differences were found between periods with regard to the proportion of infections 925.8% vs 15%). When prophylactic antibiotics were administered correctly, infection occurred in 10.2%, as compared to 31.4% when they did not fit the protocol (p < 0.05). The duration of the antibiotics was longer in period A, in infected wounds and when prophylaxis was not correct. CONCLUSIONS The correct adjustment to the protocol significantly decreases the incidence of wound infections, as well as the duration of antibiotic use. An appropriate policy of antibiotic prophylaxis in surgery is advantageous in terms of economic cost and might prevent antibiotic resistance and avoid unnecessary toxicity.

Abstract
Strategies to construct the physical map of the Trypanosoma cruzi nuclear genome have to capitalize on three main advantages of the parasite genome, namely (a) its small size, (b) the fact that all chromosomes can be defined, and many of them can be isolated by pulse field gel electrophoresis, and (c) the fact that simple Southern blots of electrophoretic karyotypes can be used to map sequence tagged sites and expressed sequence tags to chromosomal bands. A major drawback to cope with is the complexity of T. cruzi genetics, that hinders the construction of a comprehensive genetic map. As a first step towards physical mapping, we report the construction and partial characterization of a T. cruzi CL-Brener genomic library in yeast artificial chromosomes (YACs) that consists of 2,770 individual YACs with a mean insert size of 365 kb encompassing around 10 genomic equivalents. Two libraries in bacterial artificial chromosomes (BACs) have been constructed, BACI and BACII. Both libraries represent about three genome equivalents. A third BAC library (BAC III) is being constructed. YACs and BACs are invaluable tools for physical mapping. More generally, they have to be considered as a common resource for research in Chagas disease.

Abstract
Visceral leishmaniasis (VL), an endemic parasitosis in Spain, is increasing as an important opportunistic infection in AIDS patients. We describe four cases of severe haemophilic patients with end-stage HIV disease who present with visceral leishmaniasis. We report the clinical course, methods of diagnosis and response to therapy. From the assessed clinical data it does not appear to be any difference with regard to VL either in other HIV risk groups or in immunocompetent groups. In contrast with previous reports, we have found that despite their immunodepressed state, positive serology for Leishmania was found in three of the four cases. A similar observation has been made in patients with VL who are immunodepressed because of other reasons. We also confirm previous reports of poor response and intolerance of antimony treatment, the deteriorating course of the disease in AIDS patients and that there is only a slight relationship between the disease and the cause of patient death. We agree with the proposition that this pathology ought to be included in the definition critera for AIDS.

Abstract
A 14-year-old girl presented with dysphagia and weight loss. Barium swallow, computed tomography, and endoscopy showed a polypoid intraluminal mass in the cervical esophagus. The tumor was locally resected and postoperative chemotherapy and radiotherapy were administered. Histological examination of the surgical specimen established a diagnosis of synovial sarcoma. The patient remains free of discernible disease 30 months after surgery. Esophageal sarcomas are rare tumors. This appears to be the second reported case of esophageal synovial sarcoma in a child.
