Abstract
Sociologists coined the term “anomie” to describe societies that are characterized by disintegration and deregulation. Extending beyond conceptualizations of anomie that conflate the measurements of anomie as ‘a state of society’ and as a ‘state of mind’, we disentangle these conceptualizations and develop an analysis and measure of this phenomenon focusing on anomie as a perception of the ‘state of society’. We propose that anomie encompasses two dimensions: a perceived breakdown in social fabric (i.e., disintegration as lack of trust and erosion of moral standards) and a perceived breakdown in leadership (i.e., deregulation as lack of legitimacy and effectiveness of leadership). Across six studies we present evidence for the validity of the new measure, the Perception of Anomie Scale (PAS). Studies 1a and 1b provide evidence for the proposed factor structure and internal consistency of PAS. Studies 2a-c provide evidence of convergent and discriminant validity. Finally, assessing PAS in 28 countries, we show that PAS correlates with national indicators of societal functioning and that PAS predicts national identification and well-being (Studies 3a & 3b). The broader implications of the anomie construct for the study of group processes are discussed.

Abstract
There is considerable evidence for an adaptive role of inversions, but how their genetic content evolves and affects the subsequent evolution of chromosomal polymorphism remains controversial. Here, we track how life-history traits, chromosomal arrangements and 22 microsatellites, within and outside inversions, change in three replicated populations of Drosophila subobscura for 30 generations of laboratory evolution since founding from the wild. The dynamics of fitness-related traits indicated adaptation to the new environment concomitant with directional evolution of chromosomal polymorphism. Evidence of selective changes in frequency of inversions was obtained for seven of 23 chromosomal arrangements, corroborating a role for inversions in adaptation. The evolution of linkage disequilibrium between some microsatellites and chromosomes suggested that adaptive changes in arrangements involved changes in their genetic content. Several microsatellite alleles increased in frequency more than expected by drift in targeted inversions in all replicate populations. In particular, there were signs of selection in the O3+4 arrangement favouring a combination of alleles in two loci linked to the inversion and changing along with it, although the lack of linkage disequilibrium between these loci precludes epistatic selection. Seven other alleles increased in frequency within inversions more than expected by drift, but were not in linkage disequilibrium with them. Possibly these alleles were hitchhiking along with alleles under selection that were not specific to those inversions. Overall, the selection detected on the genetic content of inversions, despite limited coverage of the genome, suggests that genetic changes within inversions play an important role in adaptation.

Abstract
Clinal variation is one of the most emblematic examples of the action of natural selection at a wide geographical range. In Drosophila subobscura, parallel clines in body size and inversions, but not in wing shape, were found in Europe and South and North America. Previous work has shown that a bottleneck effect might be largely responsible for differences in wing trait-inversion association between one European and one South American population. One question still unaddressed is whether the associations found before are present across other populations of the European and South American clines. Another open question is whether evolutionary dynamics in a new environment can lead to relevant changes in wing traits-inversion association. To analyse geographical variation in these associations, we characterized three recently laboratory founded D. subobscura populations from both the European and South American latitudinal clines. To address temporal variation, we also characterized the association at a later generation in the European populations. We found that wing size and shape associations can be generalized across populations of the same continent, but may change through time for wing size. The observed temporal changes are probably due to changes in the genetic content of inversions, derived from adaptation to the new, laboratory environment. Finally, we show that it is not possible to predict clinal variation from intrapopulation associations. All in all this suggests that, at least in the present, wing traits-inversion associations are not responsible for the maintenance of the latitudinal clines in wing shape and size.

Abstract
PURPOSE We evaluated the results of esophagocoloplasty (ECP) in children by performing a 45-year retrospective cohort study in a single center. MATERIALS AND METHODS We collected all of the medical charts of patients who underwent ECP at our hospital from January 1969 to January 2014. We reviewed the medical history for each patient and then contacted the patients by phone to obtain responses to a questionnaire. The questionnaire evaluated the following four areas: overall general state, gastrointestinal function, dependence on the Health Sanitary System, and their aesthetic satisfaction. RESULTS We contacted 96 patients, and 72 completed our questionnaire. There were 45 males and 27 female respondents, with a mean age of 34.5 years. The mean Karnofsky performance status index was 96.4%. There were excellent scores obtained from 55 patients and fairly good scores from 16 patients. There was 1 patient with a low score, and there were no scores reported below 70%. Most patients (58/72) reported regular bowel habits, and no patients required drugs or other measures to facilitate defecation. Gastroesophageal reflux was present in 51 patients, and 62.8% have bothersome symptoms. Twenty-five patients used pharmacological therapies. Forty-eight patients (66.6%) were satisfied with the aesthetic result of surgery (mean score in a scale from 0 to 5, is 3). CONCLUSIONS ECP can be used in children who require esophageal substitution. The resulting long-term QoL is acceptable. However, the aesthetic outcomes remain a problem.

Abstract
BACKGROUND Our study aims at disclosing epidemiology and most relevant clinical features of esophageal atresia (EA) pointing to a model of multicentre collaboration. METHODS A detailed questionnaire was sent to all Italian Units of pediatric surgery in order to collect data of patients born with EA between January and December 2012. The results were crosschecked by matching date and place of birth of the patients with those of diagnosis-related group provided by the Italian Ministry of Health (MOH). RESULTS A total of 146 questionnaires were returned plus a further 32 patients reported in the MOH database. Basing on a total of 178 patients with EA born in Italy in 2012, the incidence of EA was calculated in 3.33 per 10,000 live births. Antenatal diagnosis was suspected in 29.5% patients. 55.5% showed associated anomalies. The most common type of EA was Gross type C (89%). Postoperative complications occurred in 37% of type C EA and 100% of type A EA. A 9.5% mortality rate was reported. CONCLUSIONS This is the first Italian cross-sectional nationwide survey on EA. We can now develop shared guidelines and provide more reliable prognostic expectations for our patients.

Abstract
Solutions containing 8 and 32 wt% myoglobin are studied by means of infrared spectroscopy, as a function of temperature (290 K and lower temperatures), in the mid- and far-infrared spectral range. Moreover, ultrafast time-resolved infrared measurements are performed at ambient temperature in the O-D stretching region. The results evidence that the vibrational properties of water remain the same in these myoglobin solutions (anharmonicity, vibrational relaxation lifetime…) and in neat water. However, the collective properties of the water molecules are significantly affected by the presence of the protein: the orientational time increases, the solid-liquid transition is affected in the most concentrated solution and the dynamical transition of the protein is observed, from the point of view of water, even in the least concentrated solution, proving that the water and myoglobin dynamics are coupled.

Abstract
The effect of intestinal colonisation on the immune system was investigated in germ-free mice monoassociated with Lactobacillus strains isolated from calf faeces. Single doses of Lactobacillus acidophilus L36 or Lactobacillus salivarius L38 were administered to germ-free mice by intragastric gavage. Ten days later, the mice were euthanised. Gene expression levels of interleukin 5 (IL-5), IL-6, IL-10, IL-12b, IL-17a, gamma interferon (IFN-γ), transforming growth factor beta 1 (TGF-β1), and tumour necrosis factor alpha (TNF-α) were quantified in segments of the small and large intestines by real time quantitative polymerase chain reaction. All the mice were colonised rapidly after Lactobacillus administration with intestinal counts ranging from 6.53 to 8.26 log cfu/g. L. acidophilus L36 administration increased the expression of cytokines involved with the Th2 (IL-5, IL-6 and TGF-β1) and Th17 (IL-17a, TNF-α and IL-6) inflammatory response, whereas L. salivarius L38 appeared to stimulate a pattern of less diversified cytokines in the intestine. Intragastric gavage of L. acidophilus L36 and L. salivarius L38 induced similar levels of colonisation in the digestive tracts of germ-free mice but stimulated different immune responses in the intestinal mucosa. The different immunomodulation patterns might facilitate the potential use of these lactobacilli as probiotics to treat distinct pathological conditions, for example protection against Citrobacter rodentium infection by stimulating IL-17 production.

Abstract
Erythrocytes are continuously exposed to risk of oxidative injury due to oxidant oxygen species. To prevent damage, they have antioxidant agents namely, catalase (Cat), glutathione peroxidase (GPx), and peroxiredoxin 2 (Prx2). Our aim was to contribute to a better understanding of the interplay between Prx2, Cat, and GPx under H2O2-induced oxidative stress, by studying their changes in the red blood cell cytosol and membrane, in different conditions. These three enzymes were quantified by immunoblotting. Malondialdehyde, that is, lipoperoxidation (LPO) in the erythrocyte membrane, and membrane-bound hemoglobin (MBH) were evaluated, as markers of oxidative stress. We also studied the erythrocyte membrane protein profile, to estimate how oxidative stress affects the membrane protein structure. We showed that under increasing H2O2 concentrations, inhibition of the three enzymes with or without metHb formation lead to the binding of Prx2 and GPx (but not Cat) to the erythrocyte membrane. Prx2 was detected mainly in its oxidized form and the linkage of metHb to the membrane seems to compete with the binding of Prx2. Catalase played a major role in protecting erythrocytes from high exogenous flux of H2O2, since whenever Cat was active there were no significant changes in any of the studied parameters. When only Cat was inhibited, Prx2 and GPx were unable to prevent H2O2-induced oxidative stress resulting in increasing MBH and membrane LPO. Additionally, the inhibition of one or more of these enzymes induced changes in the anchor/linker proteins of the junctional complexes of the membrane cytoskeleton-lipid bilayer, which might lead to membrane destabilization.

Abstract
Necrotizing enterocolitis is a gastrointestinal emergency typical of premature infants. Intestinal strictures infrequently complicate medical or surgical treatment of necrotizing enterocolitis. Postnatal cytomegalovirus infection with gastrointestinal linvolvement has occasionally been described in subjects with necrotizing enterocolitis. We report the case of a full term infant presenting necrotizing enterocolitis, acquired cytomegalovirus infection and post necrotizing enterocolitis colonic stricture.List of abbreviations: necrotizing enterocolitis = NEC,cytomegalovirus = CMV.

Abstract
Chromosomal inversions are present in a wide range of animals and plants, having an important role in adaptation and speciation. Although empirical evidence of their adaptive value is abundant, the role of different processes underlying evolution of chromosomal polymorphisms is not fully understood. History and selection are likely to shape inversion polymorphism variation to an extent yet largely unknown. Here, we perform a real-time evolution study addressing the role of historical constraints and selection in the evolution of these polymorphisms. We founded laboratory populations of Drosophila subobscura derived from three locations along the European cline and followed the evolutionary dynamics of inversion polymorphisms throughout the first 40 generations. At the beginning, populations were highly differentiated and remained so throughout generations. We report evidence of positive selection for some inversions, variable between foundations. Signs of negative selection were more frequent, in particular for most cold-climate standard inversions across the three foundations. We found that previously observed convergence at the phenotypic level in these populations was not associated with convergence in inversion frequencies. In conclusion, our study shows that selection has shaped the evolutionary dynamics of inversion frequencies, but doing so within the constraints imposed by previous history. Both history and selection are therefore fundamental to predict the evolutionary potential of different populations to respond to global environmental changes.

Abstract
OBJECTIVE We examined the reliability of the main prenatal and postnatal prognosis-related indexes that can be used to evaluate congenital diaphragmatic hernia (CDH) outcome. METHODS Seventy-seven neonates with CDH were analyzed according to CDH prognosis-related factors, divided into prenatal findings, postnatal clinical values and postnatal predictive outcome scores applied at birth and within the first 12-24 h. The data are compared between two groups: survivors and non-survivors. RESULTS During prenatal age, major associated anomalies, intrathoracic stomach, diagnosis prior to 25 weeks of gestational age and lung-to-head ratio < 0.6 were statistically significant, demonstrating their greater incidence in non-survivors. The majority of postnatal values at PICU admission were found to be reliable in identifying the CDH outcome: paO2/FiO2, oxygenation index, alveolar-arterial-O2 gradient, arterial-alveolar-O2 tension ratio, pH, mean blood pressure, body temperature. All the postnatal predictive outcome scores (Apgar 1' and 5', CDH-Study-Group equation, Score for Neonatal-Acute-Physiology II, SNAP-Perinatal-Extension II, Pediatric Risk of Mortality III and Wilford-Hall/Santa-Rosa formula) were statistically significant with more favorable values for prognosis in the survivors group. CONCLUSION The chances of predicting CDH outcome are fairly high. During prenatal age, only a few findings may be obtained. Conversely, many postnatal indexes and scores can reliably predict such outcome.

Abstract
No Brasil existem poucos estudos sobre a ocorrência da infecção pelo vírus da imunodeficiência felina (FIV), assim como a determinação dos subtipos circulantes, o que é indispensável para o desenvolvimento de vacinas e novos testes diagnósticos. O presente trabalho investigou a ocorrência da infecção pelo FIV entre os anos de 2010 e 2011 em gatos domésticos submetidos a atendimento clínico na cidade de Pelotas e região. Amostras de sangue total de 70 animais, incluindo suspeitos (28) ou não suspeitos (42) da infecção pelo FIV, foram submetidas à reação de PCR nested. Os resultados indicaram uma frequência de infecção de 15,7% (11/70) e a análise dos fatores associados (sexo, idade e condição clínica) evidenciou uma maior ocorrência em gatos com idade superior a 10 anos e acometidos por infecções crônicas e recidivantes. Oito amostras positivas na PCR nested foram submetidas a sequenciamento genômico e somente o subtipo B foi detectado na região estudada.

Abstract
BACKGROUND Germ cell tumors in females are uncommon, and bilateral metachronous ovarian teratoma is even exceptional, with sporadic cases described in the literature. CASE We report on a girl in whom a metachronous ovarian teratoma occurred 6 years after the first. The simultaneous onset of germ-line anomalies in other members of the family supports the existence of genetic or environmental factors conferring susceptibility to germ cell lesions. SUMMARY AND CONCLUSION The case here illustrated reminds the issue of the appropriate follow-up of these patients and of their families.

Abstract
BACKGROUND The present study was aimed at assessing the behavioural and physiological responsiveness of three children with profound intellectual and multiple disabilities to a set of sensory stimuli. METHODS Eighteen items, 'believed' by clinicians to be appropriate for routine interventions, were presented to the participants and responsiveness was assessed in terms of: (i) consistent behavioural and electrodermal reactions and (ii) biphasic changes in heart rate. RESULTS Results were twofold. First, all participants showed frequent consistent physiological reactions but rare consistent behavioural ones. Second, all participants showed biphasic changes in heart rate, pointing to the possibility of different appraisals (novelty and pleasantness) of most of the presented items. CONCLUSIONS Data here presented may have implications for the development and the emotional well-being of individuals with profound intellectual and multiple disabilities in that it suggests that reactions to, and potential appraisals of, sensory stimuli may occur despite the lack of consistent observable behaviours.

Abstract
Warthin tumor (papillary cystadenoma lymphomatosum, adenolymphoma) is a benign neoplasm from salivary glands and is almost restricted to the parotid gland and the periparotid lymph nodes. Its etiopathogenesis has been associated with tobacco smoke. Several authors believe that the tumor develops from heterotopic salivary gland tissues or through the attraction of a heavy lymphoid reaction. Most cases involve the lower pole or the tail of the parotid. Since its description, a few cases have been reported in other sites, like the submandibular salivary gland. This study aimed to describe a rare presentation of a Warthin tumor and discuss its etiology and differential diagnosis. A 72-year-old male patient presented an asymptomatic, nodular mass adjacent to the submandibular salivary gland. Based on clinical diagnosis of cervical lymphadenopathy, the patient underwent a surgical excision of the lesion. Histopathological exam revealed a benign neoplasm from salivary glands composed of two components: epithelial and lymphoid. The findings were consistent with Warthin tumor. Warthin tumor from submandibular salivary gland is a rare lesion. Professionals should not misinterpret their site of origin, as if they were from the lower pole or the tail of the parotid.

Abstract
Cancer cachexia is a muscle wasting condition that occurs in response to a malignant growth in the body. The mechanisms regulating cardiac muscle mass with cachexia are not well understood. Using the ApcMin/+ mouse model of colorectal cancer, we investigated how cachexia affects the regulation of 5′-adenosine monophosphate-activated protein kinase (AMPK), protein kinase B (Akt) and mammalian target of rapamycin (mTOR) signaling in the heart. Compared to age-matched C57BL/6 (BL6) mice, ApcMin/+ body mass and heart mass were lower at 12 (11±5 and 8±3%, respectively) and 20 weeks (26±3 and 6±4%, respectively) of age (P<0.05). Diminished heart mass in the 20-week-old ApcMin/+ mice coincided with a decreased rate of myofibrillar protein synthesis and increased AMPKα phosphorylation. Cachexia decreased mTOR phosphorylation and the phosphorylation of the mTOR substrates, S6 ribosomal protein and 4EBP1 independent of Akt activation. These changes in mTOR-related protein signaling were accompanied by modest increases in the amount of Beclin1 but not protein ubiquitination or cardiomyocyte apoptosis. Taken together, these data suggest that loss of cardiac mass during cachexia progression in the ApcMin/+ mouse is associated with an Akt-independent suppression of anabolic signaling and evidence of increased autophagy.

Abstract
BACKGROUND Gastrointestinal tract duplications (ATD) are rare malformations that occur with an incidence of 1 in 4000-5000 live births, with heterogeneous clinical pictures in relation to the different location and size. The purpose of this study was to analyze the role of minimally invasive surgery in the management of ATDs, through a critical analysys of 15 years of experience of the Department of Paediatric Surgery, University of Bologna. METHODS The medical records of 22 children diagnosed with ATDs were retrospectively reviewed (January 1995-August 2010). The study analyses: clinical presentation, preoperative diagnosis, site, anatomic type, treatment, and outcome. RESULTS Children were 16 males and 6 females, with age ranged from 1 day to 10 years. 20 ATDs (91%) were cystic type, while 2 cases (9%) were tubular one. During the first period of our experience, 10 (45.5%) cases were approached with an open surgery. Then subsequent 8 (36.4%) cases were treated with a diagnostic laparoscopy. This approach permitted also to perform a minilaparotomy, close to the site of the malformation, with a short length of the scar. In 2 cases (9%), we realized an ileal resection with end-to-end anastomosis with a trans-umbilical video-assisted procedure. In 2 cases (9%), we performed a complete removal of the lesions, after complete ligation of the vascular pedicle through a laparoscopic approach. 10 cases (45.5%) were located in the ileum, 6 cases (27.3%) were esophageal duplication, 3 cases (13.6%) were gastric duplications, 2 cases (9%) were located in the colon-rectum. The postoperative course was uneventful in all the cases. DISCUSSIONS AND CONCLUSIONS this study shows how, in the management of intestinal duplications, a mininvasive approach, is increasingly taking the field, along with increasing the "learning curve" with laparoscopy. In experienced hands, the laparoscopic approach allows an accurate definition of the exact site of duplication and a miniinvasive treatment with similar principles of open techniques.

Abstract
Most founding events entail a reduction in population size, which in turn leads to genetic drift effects that can deplete alleles. Besides reducing neutral genetic variability, founder effects can in principle shift additive genetic variance for phenotypes that underlie fitness. This could then lead to different rates of adaptation among populations that have undergone a population size bottleneck as well as an environmental change, even when these populations have a common evolutionary history. Thus, theory suggests that there should be an association between observable genetic variability for both neutral markers and phenotypes related to fitness. Here, we test this scenario by monitoring the early evolutionary dynamics of six laboratory foundations derived from founders taken from the same source natural population of Drosophila subobscura. Each foundation was in turn three-fold replicated. During their first few generations, these six foundations showed an abrupt increase in their genetic differentiation, within and between foundations. The eighteen populations that were monitored also differed in their patterns of phenotypic adaptation according to their immediately ancestral founding sample. Differences in early genetic variability and in effective population size were found to predict differences in the rate of adaptation during the first 21 generations of laboratory evolution. We show that evolution in a novel environment is strongly contingent not only on the initial composition of a newly founded population but also on the stochastic changes that occur during the first generations of colonization. Such effects make laboratory populations poor guides to the evolutionary genetic properties of their ancestral wild populations.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) still has a high mortality despite advanced assistance techniques. The aim of this study is to verify the validity of five respiratory and blood-gas-derived indices in defining presurgical stabilization: the oxygenation index (OI), the alveolar-arterial O(2) gradient (A-aDO(2)), the arterial-alveolar O(2) tension ratio (a/AO(2)), the arterial pH and the PaCO(2). METHODS The study involved 73 neonates with CDH where the accuracy of stabilization was assessed through the survival percentage and the contemporary behaviour of mean arterial pressure (MAP), ductal shunting, urine output and lactate levels. The trend of the indices was compared in two groups (stable/fit for surgery vs unstable/unfit for surgery) at five times (PICU admission, 6, 12, 24 hours after admission, assessment of clinical stabilization). RESULTS Fifty-five neonates were defined stabilized on the basis of the indices and underwent surgery with a 100% survival rate; 18 patients died before surgery, having never achieved clinical stabilization. MAP, ductal shunting, urine output and lactate levels were normal in the stabilized patients and altered in the non stabilized. Of the five parameters considered, all three oxygenation-linked indices (OI, A-aDO(2), a/AO(2)) are very powerful, whereas pH and PaCO(2) appears valid but more tardive. Their progressive improvement (OI<10, A-aDO(2)<250 mmHg, a/AO(2)>0.50, PaCO(2)<55 mmHg, pH>7.35) defined presurgical stabilization, thus allowing CDH surgical correction. CONCLUSION The study confirms the validity of these indices as a guide to the treatment of neonates with CDH, showing a good reliability in identifying presurgical stabilization.

Abstract
BACKGROUND Caudal block with levobupivacaine or ropivacaine is the most commonly used regional anaesthesia in children. METHODS The aim of study was to compare the cardiocirculatory profile induced in two matched groups of young patients, submitted to caudal anaesthesia with levobupivacaine or ropivacaine for an elective subumbilical surgery. Sixty children were enrolled: thirty received levopubivacaine 0.25% and thirty ropivacaine 0.2%. Intraoperative heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) were monitored at following times: Ta0 (after anaesthesia induction), Tal (after caudal anaesthesia), Ta2 (five minutes later), Ta3 (ten minutes later), Ts1 (at surgical incision), Ts2, Ts3, Ts4, Ts5 (every 10 minutes during surgery), Taw (at the awakening). RESULTS In both groups the cardiocirculatory trend remained within normal ranges at all times considered, demonstrating the safety of the method with both drugs. Both groups showed a similar trend at the different monitoring times: low decrease in HR, SBP and DBP after caudal block, slight increase in parameters after skin incision, slight decrease during surgery, increase at awakening. Regarding SBP and DBP, the levobupivacaine group children generally showed higher levels compared to the ropivacaine group, especially for DBP. CONCLUSIONS Paediatric caudal anaesthesia is an effective method with an very infrequent complication rate. Possible hypotheses for differing haemodynamic behaviour could include a stronger vasoconstriction reflex of innervated areas during caudal anaesthesia with levobupivacaine and a lower levobupivacaine induced block of the sympathetic fibers, related to different pharmacokinetic profile of low concentrations of the local anaesthetics used in paediatric epidural space.

Abstract
The urination pattern of the Mozambique tilapia (Oreochromis
mossambicus) depends on social context, and the olfactory potency
of urine released depends on social rank (males) and reproductive status
(females). This strongly suggests that urine mediates chemical communication in
this species. The current study tested, firstly, whether urine production rate
depends on sex or social status and, secondly, whether differences in urination
pattern and volume of urine stored are associated with variation in the
morphology of the urinary bladder. Finally, the effect of urination during
aggressive male–male interactions was assessed. Urine production in
catheterized fish depended neither on sex nor social status (males).
Nevertheless, males had larger kidneys than females. Dominant males had heavier
urinary bladders than subordinate males or females, mainly due to enlarged
muscle fibres, thicker urothelium and a thicker smooth muscle layer. In male
pairs wherein urination was prevented by temporary constriction of the genital
papillae, social interaction escalated to aggression (mouth-to-mouth fighting)
more rapidly and frequently than control pairs. This was accompanied by elevated
plasma testosterone and 11-ketotestosterone levels. In control encounters, the
male that initiated the aggressive behaviour was usually the winner of the
subsequent fight; this did not happen when the males could not urinate. These
results suggest that the larger, more muscular bladder of dominant males is an
adaptation, facilitating higher urination frequency, post-renal modulation and
storage of larger urine volumes for longer. It is likely that urinary pheromones
modulate aggression in male–male encounters by providing information on
the social rank and/or motivation of the emitter; males are unlikely to invest
in costly highly aggressive fights if they judge their opponent to be more
dominant. Thus, a morphological explanation for the differing urination patterns
of dominant and subordinant males, and females, has been provided, and a
possible function for this behaviour in male–male interactions is
suggested.

Abstract
UNLABELLED Machado-Joseph disease/spinocerebellar ataxia type 3 (MJD/SCA3) may rarely presents a parkinsonian phenotype. Considering that mutations in the glucocerebrosidase (GBA) gene have been associated with Parkinson disease, we investigated whether these would be more prevalent in MJD/SCA3 patients with parkinsonian manifestations than in those without them. METHODS MJD/SCA3 patients with parkinsonian features were identified and compared to relatives and to a MJD/SCA3 control group with no such features. The GBA gene was sequenced and, in a subset of patients and in normal volunteers, GBA enzyme activity was measured. RESULTS We have identified nine index MJD/SCA3 patients with parkinsonian manifestations. Overall, GBA sequence variations were found in 3/9 MJD/SCA3 index cases with parkinsonian manifestations (33%) and in 0/40 MJD/SCA3 controls without parkinsonism (p=0.03, Fisher exact test). The GBA sequence variations found were p.K(-27)R, p.E326K, and p.T369M. The latter two sequence variations were also found in two symptomatic relatives with no parkinsonian manifestations. A MJD/SCA3 relative belonging to the first positive pedigree and carrier of the p.K(-27)R mutation also presented parkinsonian manifestations. GBA activity in MJD/SCA3 patients was similar to those found in the normal control group. CONCLUSION Sequence variations at the GBA gene may play a role as a minor, modifying gene of MJD/SCA3 phenotype. This hypothetical role was not related to changes in GBA activity in peripheral leukocytes.

Abstract
The inlet patch (IP) is an area of heterotopic gastric mucosa in the cervical esophagus commonly seen during upper endoscopy. Although generally asymptomatic IP has been associated with esophageal and supraesophageal symptoms and, though rare, in adult with malignant transformation. We describe two cases of recurrent episodes of laryngospasm associated with IP. In both cases there was a good response to prolonged acid suppression therapy.

Abstract
Spontaneous aneurysms of the ductus arteriosus are rare complications of a patent ductus arteriosus. It is met at any age but it is most commonly seen in children under two months of age. Echocardiography is the best test to diagnose a ductus arteriosus, but actually the role of thoracoscopy is to help in differential diagnosis of mediastinal masses. Surgery should be recommended without delay, to avoid fatal complications, with the resection of the thrombosed aneurysm of the ductus arteriosus.

Abstract
The Authors report a proposal of recommendations concerning Minimally Invasive Surgery (MIS) in Paediatric Oncology. Since the exact role of MIS in Paediatric Oncology is still not completely defined, a restrict panel of Italian Paediatric Surgeons, some interested in Oncologic Surgery, others in MIS, prepared a schematic document, mainly founded on literature data, to provide Paediatric Surgeons with recommendations useful to approach paediatric tumours with MIS. The final draft was approved by the Italian Group of Paediatric Oncologic Surgeons. The Authors summarize the feasibility of MIS, when performed with different purposes (biopsy / resection) and timing (initial / delayed surgery) for the most common solid tumours in children. The oncologic criteria must be always followed with MIS as well as with "open" surgery.

Abstract
The purpose of this research was to design, test, and optimize a continuous microwave extraction method using temperature and residence time during and after microwave exposure as optimizing parameters for extraction of major isoflavones (genistin, genistein, daidzin, and daidzein) from soy flour. The extraction yield of four isoflavones at different heating temperatures (55 and 73 degrees C) and extraction times (0, 4, 8, 12, and 16 min) were investigated and compared with yields provided by a conventional solvent extraction method. The microwave prototype consisted of multiple, commercially available, batch-type, house-hold microwave units placed on top of each other in series to impart a continuous operation. The optimum parameters for microwave-assisted extraction of isoflavones were 73 degrees C for 8 min using a 3:1 ethanol-to soy flour ratio. At these parameters, the total yield of isoflavones extracted doubled, while the amount of oil extracted was 12%. Continuous microwave-assisted solvent extraction is a viable method for extraction of soybean isoflavones at relatively short residence times and high throughput.

Abstract
INTRODUCTION The aim of this paper was to report the management of a very rare malformative association of Left Pulmonary Artery (LPA) sling and Tracheal Lobe which is not still reported in scientific literature. MATERIALS AND METHODS The Authors describe the clinical case of a 6 years old girl that was admitted for chronic respiratory symptoms associated with recurrent upper respiratory infections. The CT-scan with virtual bronchoscopy showed an ectopic bronchus arising from the right side of the upper third of the trachea and ending in an accessory pulmonary lobe, covered by normal pleura, located in the upper mediastinum. The tracheo-broncoscopy showed a stenotic tracheal lumen with complete cartilaginous ring with an evident vascular pulsation in the middle of stenotic tract. An angio-CT confirmed the vascular anomalies with the LPA which passes between the lower trachea and the accessory tracheal bronchus and the coexistence of a persistent left superior vena cava. The surgical approach, after the thoracoscopic exploration, was a double procedure through a median sternotomy with cardiopulmonary bypass has permitted to excise completely the tracheal lobe and to reimplant the left pulmonary artery into the main pulmonary artery. RESULTS No more upper respiratory symptoms or pulmonary infections have been observed during the clinical and instrumental follow up. CONCLUSIONS Current controversy in the management of Pulmonary Artery sling include surgical approach (median sternotomy versus left thoracotomy), use or non-use of cardiopulmonary bypass, and reimplantation versus translocation with distal tracheal resection. In our experience LPA reimplantation and tracheal lobe resection have been made easily and safely by the same sternotomy utilized for the cardio-pulmonary by-pass.

Abstract
PURPOSE The jejunal-ileal atresias are the most common cause of intestinal occlusion in neonatal period and the duodenal atresia is the most common cause of high bowel obstruction in newborn. The treatment classically used is performed by a transverse sovraumbilical laparotomy. The first "minimal-invasive" approach was performed at the end of the years '70. Nowadays three clusters of thought are delineated about of mini-invasive treatment of small bowel atresias: the intestinal continuity can be established with a circumbilical incision, a totally laparoscopic technique or a laparoscopically assisted approach. It's presented our initial experience of bowel atresia in newborn treated with laparoscopically assisted approach. MATERIALS AND METHODS Three newborns with prenatal diagnosis of suspected bowel obstruction and one with suspected duodenal atresia, confirmed the diagnosis after birth, underwent to laparoscopically-assisted surgery to correct these congenital anomalies. We have treated with this procedure a duodenal atresia, two jejunal atresias and an ileal form. Surgical management was consisted of an explorative laparoscopy that allowed to recognize and isolate the pathological portion. The second step was traditional open surgery: after the exteriorization of the pathological tract through the umbilical wound, we performed the intestinal anastomosis. RESULTS In all cases the operation was completed successfully, no conversion was necessary. Intraoperatively no complications occurred. The post-operative course was uneventful. CONCLUSION The video-assisted technique for the correction of small bowel atresia adds the advantages of the classic laparotomic procedure to the laparoscopic ones.

Abstract
We describe the macroscopic anatomy of the intestine of the giraffe (Giraffa camelopardalis). The small intestine was divided into duodenum, jejunum and ileum as usual. The caecum was attached to the ileum by a long ileocaecal fold, and to the proximal ansa of the ascending colon by a caecocolic fold. The ascending colon was the most developed portion of the gross intestine and had the most complex arrangement with three ansae: the proximal ansa, the spiral ansa and the distal ansa. The proximal ansa completely encircled the caecum, describing a 360 degrees gyrus, and represented the widest portion of the intestine. The spiral ansa was formed by three and a half centripetal gyri, a central flexure and three centrifugal gyri. The last centrifugal gyrus left the spiral and described nine flexures of different form and direction over the left side of the mesentery. The two portions that formed each of these flexures ran parallel to each other. The last part of this gyrus ran parallel to the jejunum. When compared with domestic cattle, giraffe had a comparatively short small intestine and a comparatively long large intestine, with a resulting small ratio of small:large intestine. Reasons are presented why this should be considered a peculiarity of cattle-like ruminants rather than a different representative of a browser-grazer dichotomy in general.

Abstract
PURPOSE Colonic atresia and stenosis are rare causes of intestinal obstruction in the infant. Only 1.8%-15% of intestinal atresias occur in the colon. Congenital colonic stenosis is even less common than colonic atresia. Only 10 cases have been reported in Literature since 1966 and only one late-onset case has been reported in Literature until now. We describe the case of a 4-month-old baby coming to our attention because of an intestinal subocclusion due to a congenital colonic stenosis of the ascending colon. CASE REPORT A 4-month-old baby came to our attention for persistent abdominal distension, reduction of bowl function and decaying of overall clinical conditions. A plain abdominal radiograph showed distended intestinal loops with air-fluid levels and no gas in the rectum. During the barium enema the contrast medium appeared to completely fill the lumen of the colon up to the ileo-cecal valve and Cecum appearing higher than normal. Beyond the ileo-cecal valve, the contrast medium showed an abnormal hypotonic dilatation of the small intestinal loops. Suspecting an organic intestinal obstruction, an explorative laparotomy was deemed necessary and at halfway in the ascending colon a stenosis was found. RESULTS The post-operative course was uneventful and the patient is currently in good clinical conditions, has a normal diet and is thriving. CONCLUSION Considering both the Literature and our own experience, it is wise to reckon the congenital colonic stenosis as a rare but possible cause of complete or partial intestinal obstruction not only in the newborn but also throughout the first year of life.
