- Abstract
The combination of duodenal atresia (DA) and esophageal atresia (EA) is very rare. With improvements in prenatal sonography and the use of fetal magnetic resonance imaging (MRI), these malformations can be diagnosed in a more accurate and timely manner; polyhydramnios remains the most common sign despite having a low specificity. The high rate of associated anomalies (in 85% of cases) can also impact neonatal management and increase the morbidity rate; thus, it is of paramount importance to look for every possible associated malformation, such as VACTERL and chromosomic anomalies. The surgical management of this combination of atresias is not well defined and changes according to the patient's clinical status, the type of EA, and the other associated malformations. Management ranges from a primary approach for one of the atresias with delayed correction of the other (56.8%) to a simultaneous repair of both atresias (33.8%) with or without gastrostomy, or total abstention (9.4%). We suggest that a simultaneous approach can be safely performed on patients in good physical condition, with a birth weight over 1500 g, and with no major respiratory distress; this method begins by closing the tracheoesophageal fistula to protect the lung and then repairing the DA. The mortality rate has decreased over the years, dropping from 71% before 1980 to 24% after 2001. In this review, we present the available evidence on these conditions, focusing mostly on the epidemiology, prenatal diagnosis, neonatal management strategies, and outcome, with the aim of determining how the different clinical features and surgical approaches may impact on morbidity and mortality., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 French Society of Pediatrics.

- Abstract
Purpose: Adverse Drug Reactions (ADRs) leading to hospital admission was estimated to 3.6 to 21.7%. Despite its importance in terms of patients care, readmission to hospital due to ADRs remains poorly documented. The aim of our study was to investigate the rate and main characteristics of readmission for ADRs., Methods: We undertook a retrospective study during two years (2011-2012) in the post-emergency unit of Toulouse university hospital (south western, France). We selected all unplanned hospitalization for acute disease and included all cases of patients admitted twice fold or more for ADRs. Characteristics of drug-induced ADRs were assessed according to appropriate use or not., Results: Out of the 197 readmitted patients, 71 was related to ADRs (3.6%) corresponding to 17.8‰ patients-year. Mean age was 82.3 years and 67% were women. The most frequent ADRs found were vascular (n=41, 18.4%), gastro-intestinal (n=28, 12.6%), cardiac (n=28, 12.6%), neurologic (n=26, 11.7%), metabolic (n=26, 10.3%) and psychiatric (n=24, 9.9%). The drugs mainly involved were psychoactive, cardiovascular, digestive or antithrombotic agents. The context of occurrence of ADRs was related to inappropriate drug prescription in 56% of cases. A total of 24 patients were admitted twice for the same ADR and 2 others three times. For 22 patients (30.9%), the same drugs were involved., Conclusion: Our data show hospital readmission was due to ADRs in 3.6% of cases. In 1.1% of cases, the same couple "drug-ADR" was involved. Furthermore, in 56% of cases, repeated admissions are related to an inappropriate drug prescription., (Copyright © 2015. Published by Elsevier SAS.)

- Abstract
Purpose: In vivo dosimetry transit using portal imaging is a promising approach for quality assurance in radiotherapy. A comparative evaluation was conducted between a commercial solution, EPIgray(®) and an in vivo dosimetry control reference using semiconductors diodes., Material and Methods: The performance of the two in vivo dosimetry methods was assessed. The primary endpoint was the dose deviation between the reconstructed dose at the prescription point and the measured dose using the ionization chamber in phantoms or the calculated predictive dose by the treatment planning system with patients. The deviation threshold was set to ±5%. In total, 107 patients were prospectively included and treated with 3D-conformal radiotherapy (3D-CRT) or intensity-modulated radiotherapy (IMRT) techniques for tumours of the brain, chest and head and neck., Results: The dosimetric accuracy of EPIgray(®) in phantom were comparable to diodes in terms of repeatability (0.11%), reproducibility (0.29-0.51%) with a mean dose deviation of 0.17% (SD: 1.11). The rates of radiotherapy sessions out of the tolerance for the brain (3D-CRT and IMRT), thorax (3D-CRT) and the head and neck (IMRT) were respectively 0%, 9.6% and 5.3% with a mean dose deviation ranging between 0.49% and 1.53%. The mean of dose deviation between three consecutive sessions with EPIgray(®) validates 99.1% of treatments., Conclusion: The performance of EPIgray(®) in in vivo dosimetry is consistent with the recommendations of the European Society for Radiotherapy and Oncology (ESTRO) and equivalent to semiconductor diodes for 3D-CRT. It also allows adequate control for IMRT, which is technically difficult to perform with the diodes., (Copyright © 2014 Société française de radiothérapie oncologique (SFRO).

- Abstract
Purpose: In vivo dosimetry is now widely recommended to avoid major treatment error. Transit dosimetry using portal imagers allows fast and accurate in vivo dose verifications. Several teams have published clinical studies but no recommendation has been proposed to define tolerance levels and validation criteria. This study proposes a simple methodology to assess the overall standard deviation of transit dosimetry and was applied to our transit dosimetry method., Material and Methods: In a first step, the uncertainties due to the dose reconstruction method are evaluated. Their estimation is based on a set of geometries, representative of clinical situations for which 45 points of measurement have been defined. In a second step, we studied the variations of our method in clinical situations. During the treatment session of the patient, the dose was reconstructed and the differences between reconstructed dose and prescribed dose were used to define a realistic tolerance level, adapted to the clinical routine. Then, a methodology is proposed to determine if the transit dosimetry method, with the defined tolerance level allows detecting significant treatment errors (>5% of the prescribed dose). RESULTS - , Conclusion: Applying this methodology we concluded that a tolerance level of 6.5% (k=2) can be associated with our method. With this value, it is demonstrated that in many cases differences of 5% (or less) on the prescribed dose can be detected. This study demonstrates clearly that in vivo transit dosimetry is not able to detect all the treatment errors but remains an ultimate and efficient tool in many situations., (Copyright © 2013 Société française de radiothérapie oncologique (SFRO).

- Abstract
Anorectal malformations (ARM) are the result of an abnormal development of the terminal part of the digestive tract interesting anus and/or rectum that occur early between the sixth and tenth week of embryonic development. They carry a malformation spectrum of severity depending on the level of disruption of the anorectal canal and of the associated caudal malformations (sacrum and spine). ARM are associated in over half the cases with other malformations that can be integrated in some cases in known syndromes. If surgical treatment to restore anatomy as normal as possible is indispensable, post-operative care is essential for these patients whose defecation mechanisms are altered, to reach if not continence, at least a socially acceptable cleanliness., (Copyright © 2013 Elsevier Masson SAS.

- Abstract
Pain associated with vaso-occlusive crisis is the main cause of hospitalization in children with sickle cell disease. Recent studies have suggested that pain might have a neuropathic component. Lidocaine patches are commonly prescribed as a topical analgesic in adult neuropathic pain. This study reports the efficacy and safety of such treatment in 6 patients with sickle cell disease, aged 6-18 years, who had been hospitalized for vaso-occlusive crisis after failure of the standard analgesic treatment. These data have led to setting up a confirmatory phase II trial, which is currently underway., (Copyright © 2013 Elsevier Masson SAS. All rights reserved.)

- Abstract
Neisseria meningitidis is associated with severe invasive infections such as meningitis and fulminant septicemia. Septic arthritis due to N. meningitidis is rare and bone infections have been reported exceptionally. We report the case of a 7-year-old boy who presented with septic arthritis of the right hip associated with a septic location on the pelvis and pyomyositis of the adjacent muscle. Culture of the joint fluid was sterile but universal 16S polymerase chain reaction (PCR) of this fluid revealed group B N. meningitidis. Our patient had never presented any symptoms of meningitis or septicemia and blood cultures were all sterile. Despite appropriate antibiotic treatment, the course of the disease was unusually long and his status did not improve until surgical lavage of the hip was performed. Moreover, MRI imaging showed bilateral hypersignals of the adjacent muscles and revealed an abscess formation in the left gluteus maximus muscle. Presumptive diagnosis bacterial myositis was confirmed by an elevation of creatine phosphokinase in the sera up to 21-fold the normal value but the culture of the abscess, performed 10 days after initiation of antibiotics, was sterile. Despite an initially unfavorable course, this patient's status improved after surgical drainage and he fully recovered 1 month later. This observation illustrates an unusual presentation of invasive meningococcal infection. The respective roles of infection and an inflammatory phenomenon during the course of the disease are discussed. Moreover, this case emphasizes the value of PCR for bacteriological diagnosis of bone and joint infections., (Copyright © 2012. Published by Elsevier SAS.)

- Abstract
Background: Most non-small-cell lung cancer (NSCLC) patients receive cisplatin-based chemotherapy though clinical response is restricted to a subset of patients. DNA repair protein levels are possible surrogates for cisplatin-induced DNA adduct (and subsequent cell death) repair efficiency and thus molecular determinants of therapeutic efficacy. The International Adjuvant Lung Trial (IALT)-Bio study previously suggested ERCC1 and MSH2 as predictive of cisplatin-based therapeutic benefit., Patients and Methods: DNA repair protein expression (XPF, BRCA1, ERCC1, MSH2, p53, PARP1, and ATM) was assessed by immunohistochemistry on a large subset of patients (N = 769) from the IALT trial. Tissue Microarray slides were digitally scanned and signal quantified by user-defined macros. Statistical analyses (univariate and multivariate) of 5-year disease-free survival (DFS) and 5-year overall survival used binary cut-offs (H score low/high expression)., Results: In patients with squamous cell carcinoma (SCC), ATM, p53, PARP1, ERCC1, and MSH2 displayed significant (borderline) predictive values, mainly on DFS with chemotherapy efficacy limited to low marker levels. Adenocarcinoma (ADC) results were not significant. BRCA1 and XPF were not significant for predictive modeling in either SCC or ADCs., Conclusion: Here predictive utility of DNA repair enzymes co-segregates with SCC histology, focusing their predictive value to this histological subclass of NSCLC. Distinct mechanisms of chemotherapeutic response or resistance might exist among histological subclasses of solid tumors.

- Abstract
The vaginal flora of a healthy woman is composed of the Doderleïn bacilli (different species of lactobacilli) forming a biofilm on the mucosa. These bacteria have a beneficial effect by inhibiting growth, adhesion or spread of other microorganisms. Different mechanisms are recognized, including secretion of organic acids, production of antimicrobial substances (hydrogen peroxide, bacteriocins and biosurfactants), competition for nutrients (arginine deiminase), competition for receptors (adhesion on the epithelium), steric exclusion (biosurfactants, adhesion on the epithelium or on the fibronectin) and co-aggregation. This ecological balance can be disturbed by drugs (antibiotics and spermicides) or by local devices. A new therapeutic approach has been proposed to restore a normal flora: the use of probiotics by the association of different lactobacilli with combined antimicrobial activity.
