Abstract
PURPOSE To determine the incidence of enterocutaneous fistulas (ECFs) developed after elective incisional hernia (IH) repair using intraperitoneal uncoated polypropylene (PPE) mesh. METHODS This is a retrospective descriptive study of a prospective cohort of patients undergoing elective IH repair using intraperitoneal uncoated PPE mesh at the Department of General Surgery of a high complexity University Hospital. RESULTS Between January 1992 and December 2013, 695 IH repairs were performed using intraperitoneal uncoated PPE mesh. The omentum was placed between the mesh and bowel in 507 patients (73 %). In 188 patients (27 %) it was not possible to place the omentum between the mesh and bowel; therefore, in 69 patients (9.92 %) the PPE mesh was placed over the bowel, whereas in 119 patients (17.12 %) a Vicryl® mesh was placed between the bowel and PPE mesh. Six hundred and seventy-eight (97.5 %) IH repairs were open whereas 17 (2.5 %) were laparoscopic. Postoperative complications consisted of seroma (5.9 %), hematoma (4.3 %), wound infection (4.8 %), and mesh infection (4.0 %). Recurrence of IH occurred in 52 patients (7.4 %) after a mean follow-up of 59 months. Four (0.5 %) patients required additional surgery due to intestinal occlusion. Neither acute nor chronic ECFs were encountered during follow-up in 695 patients. CONCLUSION Based on these results, the placement of intraperitoneal uncoated PPE mesh for elective IH repair might be a safe procedure that is not associated with ECF formation.

Abstract
SETTING In 2012, Peru's National Tuberculosis Program (NTP) reported that children aged 0-14 years accounted for 7.9% of the country's tuberculosis (TB) incidence. This figure is likely an underestimate due to suboptimal diagnosis of childhood TB. OBJECTIVE To identify barriers to childhood TB diagnosis in Lima, Peru. DESIGN Using semi-structured guides, moderators conducted in-depth interviews with four NTP administrators and five pulmonologists specializing in TB and 10 focus groups with 53 primary care providers, community health workers (CHWs), and parents and/or guardians of pediatric TB patients. Two authors independently performed inductive thematic analysis and identified emerging themes. RESULTS Participants identified five barriers to childhood TB diagnosis: ignorance and stigma among the community, insufficient contact investigation, limited access to diagnostic tests, inadequately trained health center staff, and provider shortages. CONCLUSION Recent efforts to increase childhood TB detection have centered on the development of new technologies. However, our findings demonstrate that many diagnostic barriers are rooted in socio-economic and health system problems. Potential solutions include implementing multimedia campaigns and community education to reduce ignorance and stigma, prioritizing contact investigation for high-risk households, and training primary care providers and CHWs to recognize and evaluate childhood TB.

Abstract
Among atomically thin two-dimensional (2D) materials, molybdenum disulfide (MoS2) is attracting considerable attention because of its direct bandgap in the 2H-semiconducting phase. On the other hand, a 1T-metallic phase has been revealed, bringing complementary application. Recently, thanks to top-down fabrication using electron beam (EB) irradiation techniques, in-plane 1T-metal/2H-semiconductor lateral (Schottky) MoS2 junctions were demonstrated, opening a path toward the co-integration of active and passive two-dimensional devices. Here, we report the first transport measurements evidencing the formation of a MoS2 Schottky barrier (SB) junction with barrier height of 0.13-0.18 eV created at the interface between EB-irradiated (1T)/nonirradiated (2H) regions. Our experimental findings, supported by state-of-the-art simulation, reveal unique device fingerprint of SB-based field-effect transistors made from atom-thin 1T layers.

Abstract
UNLABELLED Aromatic L-amino acid decarboxylase (AADC) deficiency is an autosomal recessive inborn error of metabolism, affecting catecholamines and serotonin biosynthesis. Cardinal signs consist in psychomotor delay, hypotonia, oculogyric crises, dystonia, and extraneurological symptoms. PATIENTS AND METHODS We present a retrospective descriptive multicentric study concerning ten French children with a biochemical and molecular confirmed diagnosis of AADC deficiency. RESULTS Clinical presentation of most of our patients was consistent with the previous descriptions from the literature (hypotonia (nine children), autonomic signs (nine children), sleep disorders (eight children), oculogyric crises (eight children), motor disorders like hypertonia and involuntary movements (seven children)). We described however some phenotypic particularities. Two patients exhibited normal intellectual abilities (patients already described in the literature). We also underlined the importance of digestive symptoms like diarrhea, which occurred in five among the ten patients. We report in particular two children with chronic diarrhea, complicated by severe failure to thrive. Vanillactic acid (VLA) elevation in urines of one of these two patients led to suspect the diagnosis of AADC deficiency, as in two other patients from our population. CONCLUSION Some symptoms like chronic diarrhea were atypical and have been poorly described in the literature up to now. Diagnosis of the AADC deficiency is sometimes difficult because of the phenotypic heterogeneity of the disease and VLA elevation in urines should suggest the diagnosis.

Abstract
The aim of this study was to investigate the relationship between the geometry of the proximal femur and the incidence of intra-operative fracture during uncemented total hip arthroplasty (THA). We studied the pre-operative CT scans of 100 patients undergoing THA with an uncemented femoral component. We measured the anteroposterior and mediolateral dimensions at the level of division of the femoral neck to calculate the aspect ratio of the femur. Wide variations in the shape of the femur were observed, from round, to very narrow elliptic. The femurs of women were narrower than those of men (p < 0.0001) and small femurs were also narrower than large ones. Patients with an intra-operative fracture of the calcar had smaller and narrower femurs than those without a fracture (p < 0.05) and the implanted Corail stems were smaller in those with a fracture (mean size 9 vs 12, p < 0.0001). The variability of the shape of the femoral neck at the level of division contributes to the understanding of the causation of intra-operative fractures in uncemented THA.

Abstract
The tegument of all herpesviruses contains a capsid-bound large protein that is essential for multiple viral processes, including capsid transport, decapsidation at the nuclear pore complex, particle assembly, and secondary envelopment, through mechanisms that are still incompletely understood. We report here a structural characterization of the central 970 residues of this protein for herpes simplex virus type 1 (HSV-1 UL36, 3164 residues). This large fragment is essentially a 34-nm-long monomeric fiber. The crystal structure of its C terminus shows an elongated domain-swapped dimer. Modeling and molecular dynamics simulations give a likely molecular organization for the monomeric form and extend our findings to alphaherpesvirinae. Hence, we propose that an essential feature of UL36 is the existence in its central region of a stalk capable of connecting capsid and membrane across the tegument and that the ability to switch between monomeric and dimeric forms may help UL36 fulfill its multiple functions.

Abstract
Objectives Rotator cuff tears are among the most common and debilitating
upper extremity injuries. Chronic cuff tears result in atrophy and
an infiltration of fat into the muscle, a condition commonly referred
to as ‘fatty degeneration’. While stem cell therapies hold promise
for the treatment of cuff tears, a suitable immunodeficient animal
model that could be used to study human or other xenograft-based
therapies for the treatment of rotator cuff injuries had not previously
been identified. Methods A full-thickness, massive supraspinatus and infraspinatus tear
was induced in adult T-cell deficient rats. We hypothesised that,
compared with controls, 28 days after inducing a tear we would observe
a decrease in muscle force production, an accumulation of type IIB
fibres, and an upregulation in the expression of genes involved
with muscle atrophy, fibrosis and inflammation. Results Chronic cuff tears in nude rats resulted in a 30% to 40% decrease
in muscle mass, a 23% reduction in production of muscle force, and
an induction of genes that regulate atrophy, fibrosis, lipid accumulation,
inflammation and macrophage recruitment. Marked large lipid droplet
accumulation was also present. Conclusions The extent of degenerative changes in nude rats was similar to
what was observed in T-cell competent rats. T cells may not play
an important role in regulating muscle degeneration following chronic
muscle unloading. The general similarities between nude and T-cell
competent rats suggest the nude rat is likely an appropriate preclinical
model for the study of xenografts that have the potential to enhance
the treatment of chronically torn rotator cuff muscles. Cite this article: Bone Joint Res 2014;3:262–72.

Abstract
OBJECTIVE We investigated the link between DNA hypomethylation and clinical penetrance in facioscapulohumeral dystrophy (FSHD) because hypomethylation is moderate and heterogeneous in patients and could not thus far be correlated with disease presence or severity. METHODS To investigate the link between clinical signs of FSHD and DNA methylation, we explored 95 cases (37 FSHD1, 29 asymptomatic individuals carrying a shortened D4Z4 array, 9 patients with FSHD2, and 20 controls) by implementing 2 approaches: methylated DNA immunoprecipitation and sodium bisulfite sequencing. RESULTS Both methods revealed statistically significant differences between asymptomatic carriers or controls and individuals with clinical FSHD, especially in the proximal region of the repeat. Absence of clinical expression in asymptomatic carriers is associated with a level of methylation similar to controls. CONCLUSIONS We provide a proof of concept that the targeted approaches that we describe could be applied systematically to patient samples in routine diagnosis and suggest that local hypomethylation within D4Z4 might serve as a modifier for clinical expression of FSHD phenotype. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that assays for hypomethylation within the D4Z4 region accurately distinguish patients with FSHD from individuals with D4Z4 contraction without FSHD.

Abstract
Verotoxin-producing Escherichia coli (VTEC) strains are the cause of food-borne and waterborne illnesses around the world. Traditionally, surveillance of the human population as well as the environment has focused on the detection of E. coli O157:H7. Recently, increasing recognition of non-O157 VTEC strains as human pathogens and the German O104:H4 food-borne outbreak have illustrated the importance of considering the broader group of VTEC organisms from a public health perspective. This study presents the results of a comparison of three methods for the detection of VTEC in surface water, highlighting the efficacy of a direct VT immunoblotting method without broth enrichment for detection and isolation of O157 and non-O157 VTEC strains. The direct immunoblot method eliminates the need for an enrichment step or the use of immunomagnetic separation. This method was developed after 4 years of detecting low frequencies (1%) of E. coli O157:H7 in surface water in a Canadian watershed, situated within one of the FoodNet Canada integrated surveillance sites. By the direct immunoblot method, VTEC prevalence estimates ranged from 11 to 35% for this watershed, and E. coli O157:H7 prevalence increased to 4% (due to improved method sensitivity). This direct testing method provides an efficient means to enhance our understanding of the prevalence and types of VTEC in the environment. This study employed a rapid evidence assessment (REA) approach to frame the watershed findings with watershed E. coli O157:H7 prevalences reported in the literature since 1990 and the knowledge gap with respect to VTEC detection in surface waters.

Abstract
AIMS To describe the rehabilitation of non-ambulatory children with cerebral palsy and to explore adjustability on their individual needs. MATERIAL AND METHOD Data described are extracted from an on-going national cohort study, following during 10years 385 children with cerebral palsy, aged from 4 to 10, Gross Motor Function Classification System IV and V. We analysed data from the first 190 patients (mean age 6years 10months (SD 2.0), 111 boys), focusing on physiotherapy, ergotherapy, psychomotility and speech therapy in medico-social and liberal sectors. RESULTS In medico-social sector, duration of paramedical care is significantly more important than in liberal sector (structure of care: median=4.25h/week, liberal sector: median=2.00h/week) (P<0.0001). More than 4 different types of care per week are given in medico-social sector, while in liberal sector children benefit from only 2 different types of care a week. In investigators opinion, rehabilitation in structures of care is 71.65% adapted as opposed to 18.75% in the liberal sector (P<0.001). Children level V have less time of rehabilitation than the others (P=0.0424). INTERPRETATION Rehabilitation of children with cerebral palsy who are not able to walk, with an objective to improve quality of life, is truly multidisciplinary and suitable in medico-social sector.

Abstract
Facioscapulohumeral muscular dystrophy (FSHD) is one of the most prevalent adult muscular dystrophies. The common clinical signs usually appear during the second decade of life but when the first molecular dysregulations occur is still unknown. Our aim was to determine whether molecular dysregulations can be identified during FSHD fetal muscle development. We compared muscle biopsies derived from FSHD1 fetuses and the cells derived from some of these biopsies with biopsies and cells derived from control fetuses. We mainly focus on DUX4 isoform expression because the expression of DUX4 has been confirmed in both FSHD cells and biopsies by several laboratories. We measured DUX4 isoform expression by using qRT-PCR in fetal FSHD1 myotubes treated or not with an shRNA directed against DUX4 mRNA. We also analyzed DUX4 downstream target gene expression in myotubes and fetal or adult FSHD1 and control quadriceps biopsies. We show that both DUX4-FL isoforms are already expressed in FSHD1 myotubes. Interestingly, DUX4-FL expression level is much lower in trapezius than in quadriceps myotubes, which is confirmed by the level of expression of DUX4 downstream genes. We observed that TRIM43 and MBD3L2 are already overexpressed in FSHD1 fetal quadriceps biopsies, at similar levels to those observed in adult FSHD1 quadriceps biopsies. These results indicate that molecular markers of the disease are already expressed during fetal life, thus opening a new field of investigation for mechanisms leading to FSHD.
