IGMPlot: A program to identify, characterize, and quantify molecular interactions.

We describe the development and features of a program called IGMPlot, which is based on the independent gradient model (IGM) and its local descriptor δ g . The IGM approach analyzes the gradient of the electron density (ED) in a molecular system to identify regions of space where chemical interactions take place. IGMPlot is intended for use by both experimental scientists and theoretical chemists. It is standalone software written in C++, with versions available for multiple platforms. Some key features are: probing and quantifying interactions between two given molecular fragments, determining bond strength (IBSI), estimating the atomic contributions to an intermolecular interaction and preparing data to build 2D and 3D representations of interaction regions. The software has been updated to include new features: critical point analysis of the ED, assessing ED asymmetry of a given bond (PDA) and a new descriptor called q g designed to enhance the IGM- δ g analysis. The program can be found at: http://igmplot.univ-reims.fr.

[Vulvar mass in neonatal period : spot the difference]. / Diagnostic différentiel d'une masse vulvaire en période néonatale.

We report the cases of two female newborns who present, at the first day, a interlabial mass. In both cases, the antenatal scans were normal, and the clinical examination in the delivery room didn't reveal any other abnormality. Similar features may suggest the same diagnosis. However, in the first case, it is a paraurethral cyst which causes the bulging of vaginal introitus whereas, in the second infant, it is an imperforated hymen. Paraurethral cysts are uncommon and even more so among infants. The diagnosis is primarily clinical, and ultrasound confirms the diagnosis and verifies the absence of other associated anomalies. These cysts usually resolve spontaneously. Rarely, they can lead to urinary retention. The second diagnosis, imperforate hymen, is the most common congenital malformation of the female genital tract. It can lead to hydrocolpos with the upstream accumulation of vaginal secretion and sometimes induce a hydrometrocolpos, with vaginal and uterine dilatation. The resulting mass can cause obstruction of surrounding urinary or digestive structures. Surgical management is generally necessary.

Nous rapportons le cas de deux nouveau-nés de sexe féminin qui présentaient une masse au niveau vulvaire, dans les premiers jours de vie. Dans les deux cas, le reste de l'examen clinique était sans particularité et aucune anomalie n'avait été décelée en anténatal. Les présentations cliniques semblables peuvent faire évoquer le même diagnostic. Pourtant, dans le premier cas, c'est un kyste para-urétral qui cause la masse alors que, dans le second, c'est une imperforation de l'hymen. Ces deux pathologies sont peu fréquentes chez les nourrissons. Leur diagnostic est avant tout clinique et l'échographie permet à la fois de confirmer celui-ci et de vérifier l'absence d'autres anomalies. La plupart du temps, les kystes para-urétraux régressent spontanément. Cependant, ils peuvent parfois être la cause d'une rétention urinaire. En cas d'imperforation de l'hymen, la réalisation d'un acte chirurgical est, par contre, nécessaire afin d'éviter des complications plus tardives. Un hydrocolpos peut y être associé, il est dû à la rétention de sécrétions vaginales en amont. La masse engendrée peut provoquer une obstruction des structures avoisinantes.

[A case of severe congenital nephrotic syndrome secondary to NPHS1 mutation]. / Syndrome néphrotique congénital sévère avec mutation NPH S1.

The congenital nephrotic syndrome is a rare and severe pathology, and its management represents a real challenge for pediatric nephrologists. We report the case of a congenital nephrotic syndrome secondary to a homozygous mutation of the NPHS1. The young patient has a severe clinical course, and benefits of a management by anti-proteinuric treatment and a unilateral nephrectomy. This clinical case illustrates the difficulties of the management of a severe congenital nephrotic syndrome. To date, it is difficult to identify these patients beforehand because there is a poor correlation between the genotype and the phenotype of the NPHS1 mutation. There are two managements described in the literature: an early bilateral nephrectomy at 7 kg of weight with a renal transplant around 10 kg, versus a conservative management via an anti-proteinuric treatment and/or an unilateral nephrectomy. Current evidence is based on retrospective studies and the choice of a conservative approach versus early bilateral nephrectomy should take into account the severity of protein loss and its complications.

Le syndrome néphrotique congénital est une pathologie rare et sévère, dont la prise en charge représente un défi pour les néphrologues pédiatriques. Nous rapportons le cas d'un jeune patient présentant cette pathologie secondaire à une mutation homozygote du gène NPHS1. Il présente un tableau clinique sévère et bénéficie d'un traitement anti-protéinurique et d'une néphrectomie unilatérale. Ce cas clinique illustre les difficultés de la prise en charge des cas sévères, dont l'identification préalable est difficile à ce jour car la corrélation entre le génotype et le phénotype de la mutation NPHS1 est pauvre. Il existe deux prises en charges décrites dans la littérature : une néphrectomie bilatérale précoce vers 7 kg de poids et une greffe rénale vers 10 kg, ou bien une prise en charge conservative via un traitement anti-protéinurique et/ou une néphrectomie unilatérale permettant de postposer la greffe. Les données actuelles n'étant basées que sur des études rétrospectives, le choix entre une approche conservative et une néphrectomie bilatérale précoce doit prendre en compte la sévérité de la déperdition protéique et ses complications.

[Late preterm : high risk newborns despite appearances]. / La prématurité tardive : des nourrissons fragiles malgré les apparences.

Late preterm infants are born between 34 weeks of amenorrhea and 36 weeks 6 days. Late preterms represent the largest proportion of premature infants (about 75 %). Late prematurity is increasing in recent decades. While studies initially focused on mortality and morbidity related to very preterm birth, the late preterms have been the subject of increased attention over the past 15 years. Late preterm infants have an increased risk of respiratory complications, infections, feeding problems, hypothermia and hypoglycemia. Neonatal, infant and during adulthood mortalities are significantly higher in late preterm than in term infants. In addition, late preterm infants carry an increased risk of long-term morbidities, such as neurodevelopmental delay, cerebral palsy, chronic respiratory or metabolic diseases. This review highlights the evidence that late preterm infants are high risk newborns and require adapted follow-up.

Les enfants nés entre 34 semaines d'aménorrhée et 36 semaines 6 jours sont dans la période de prématurité tardive. Ils sont également appelés «late-preterm¼. Ces enfants représentent près de 75 % des naissances prématurées dans les pays industrialisés. Cette prématurité tardive est en augmentation croissante sur les dernières décennies. Alors qu'initialement les études se concentraient essentiellement sur la mortalité et les morbidités liées à la grande prématurité, la population des prématurés tardifs a fait l'objet d'une attention accrue ces 15 dernières années. Il est ainsi démontré que ces enfants présentent un risque accru de complications respiratoires, d'infections, de problèmes d'alimentation, d'hypothermie et d'hypoglycémie. La mortalité néonatale, infantile et jusqu'à l'âge adulte des late-preterm est significativement plus élevée que chez les nouveau-nés à terme. De plus, les morbidités à long terme, tels que le retard neurodéveloppemental, l'infirmité motrice cérébrale, les pathologies respiratoires chroniques ou métaboliques, sont significativement plus élevées. A travers cette revue de la littérature, nous revoyons ces risques, qui contribuent à faire des «late preterm¼ une population fragile et nécessitant un suivi adapté.

[Therapeutic advances in neonatology]. / Actualités thérapeutiques en néonatologie.

In this article, we will review major therapeutic advances in neonatology over the past ten years. We will discuss the antenatal administration of magnesium sulfate, the interest of hypothermia in the context of hypoxic ischaemic encephalopathy, the benefits and modalities of placental transfusion, less invasive techniques for ventilation and administration of the surfactant, possibilities to fortify breast milk and the concept of developmental care. These therapeutic advances are sometimes based on new therapeutics, sometimes on new concepts and, sometimes, on new less invasive techniques. They have made it possible to optimize the care of premature babies but also of term newborns.

Dans cet article, nous allons passer en revue les grandes avancées thérapeutiques dans le domaine de la néonatologie au cours des dix dernières années. Nous traiterons de l'administration anténatale du sulfate de magnésium, de l'intérêt de l'hypothermie contrôlée dans le cadre de l'encéphalopathie d'origine hypoxo-ischémique, des bénéfices et modalités de la transfusion placentaire, des techniques moins invasives pour la ventilation et pour l'administration du surfactant, de la fortification du lait maternel et du concept de soins de développement. Ces avancées thérapeutiques reposent tantôt sur des nouveautés thérapeutiques, tantôt sur de nouveaux concepts et, parfois, sur de nouvelles techniques moins invasives. Elles ont permis d'optimiser la prise en charge des prématurés, mais aussi des nouveau-nés à terme.

Sentinel lymph node biopsy without axillary lymphadenectomy after neoadjuvant chemotherapy is accurate and safe for selected patients: the GANEA 2 study.

PURPOSE: GANEA2 study was designed to assess accuracy and safety of sentinel lymph node (SLN) after neo-adjuvant chemotherapy (NAC) in breast cancer patients. METHODS: Early breast cancer patients treated with NAC were included. Before NAC, patients with cytologically proven node involvement were allocated into the pN1 group, other patient were allocated into the cN0 group. After NAC, pN1 group patients underwent SLN and axillary lymph node dissection (ALND); cN0 group patients underwent SLN and ALND only in case of mapping failure or SLN involvement. The main endpoint was SLN false negative rate (FNR). Secondary endpoints were predictive factors for remaining positive ALND and survival of patients treated with SLN alone. RESULTS: From 2010 to 2014, 957 patients were included. Among the 419 patients from the cN0 group treated with SLN alone, one axillary relapse occurred during the follow-up. Among pN1 group patients, with successful mapping, 103 had a negative SLN. The FNR was 11.9% (95% CI 7.3-17.9%). Multivariate analysis showed that residual breast tumor size after NAC ≥ 5 mm and lympho-vascular invasion remained independent predictors for involved ALND. For patients with initially involved node, with negative SLN after NAC, no lympho-vascular invasion and a remaining breast tumor size 5 mm, the risk of a positive ALND is 3.7% regardless the number of SLN removed. CONCLUSION: In patients with no initial node involvement, negative SLN after NAC allows to safely avoid an ALND. Residual breast tumor and lympho-vascular invasion after NAC allow identifying patients with initially involved node with a low risk of ALND involvement.

Left heart disease: a frequent cause of early pulmonary hypertension in systemic sclerosis, unrelated to elevated NT-proBNP levels or overt cardiac fibrosis but associated with increased levels of MR-proANP and MR-proADM: retrospective analysis of a French Canadian cohort.

OBJECTIVES: Pulmonary hypertension (PH) causes mortality in systemic sclerosis (SSc). Pulmonary arterial hypertension (PAH) and left heart disease (LHD) are frequent causes of PH. Therefore, we studied PAH and LHD in early PH. METHOD: A total of 432 French Canadian SSc patients were studied retrospectively. All underwent screening for PH. We analysed clinical, serological, and radiographic data from 26 patients with early PH diagnosed by right heart catheterization (RHC). SSc patients with (n = 21) and without PH (n = 19) were prospectively re-evaluated by cardiac magnetic resonance imaging (MRI) and serial measurements of N-terminal pro-brain natriuretic peptide (NT-proBNP) and the haemodynamic biomarkers mid-regional pro-atrial natriuritic peptide (MR-proANP) and mid-regional pro-adrenomedullin (MR-proADM). RESULTS: The most frequent cause of early PH was LHD (58%). PAH was seen in 34% of patients. No association was found between the type of PH and autoantibodies. Early LHD-PH, but not early PAH, was associated with lower NT-proBNP (p = 0.024), but MR-proANP and MR-proADM levels were higher in early LHD-PH than in patients without PH (p = 0.014 and p = 0.012, respectively). Only one patient had abnormal cardiac MRI explaining LHD-PH. CONCLUSIONS: Early PH in SSc, like late PH, is heterogeneous and RHC is essential for determining its underlying cause. The most frequent cause of early PH was LHD. Levels of MR-proANP and MR-proADM, but not NT-proBNP, were increased in early LHD-PH, and may be more reliable than NT-proBNP as a biomarker of early PH in this subgroup of patients. Cardiac MRI did not explain LHD-PH. This study is the first to identify a high frequency of LHD in early PH correlating with normal NT-proBNP levels but increased MR-proANP and MR-proADM levels in SSc patients.

Cytogenetics in the management of mature B-cell non-Hodgkin lymphomas: Guidelines from the Groupe Francophone de Cytogénétique Hematologique (GFCH).

Non-Hodgkin lymphomas (NHL) consist of a wide range of clinically, phenotypically and genetically distinct neoplasms. The accurate diagnosis of mature B-cell non-Hodgkin lymphoma relies on a multidisciplinary approach that integrates morphological, phenotypical and genetic characteristics together with clinical features. Cytogenetic analyses remain an essential part of the diagnostic workup for mature B-cell lymphomas. Karyotyping is particularly useful to identify hallmark translocations, typical cytogenetic signatures as well as complex karyotypes, all bringing valuable diagnostic and/or prognostic information. Besides the well-known recurrent chromosomal abnormalities such as, for example, t(14;18)(q32;q21)/IGH::BCL2 in follicular lymphoma, recent evidences support a prognostic significance of complex karyotype in mantle cell lymphoma and Waldenström macroglobulinemia. Fluorescence In Situ Hybridization is also a key analysis playing a central role in disease identification, especially in genetically-defined entities, but also in predicting transformation risk or prognostication. This can be exemplified by the pivotal role of MYC, BCL2 and/or BCL6 rearrangements in the diagnostic of aggressive or large B-cell lymphomas. This work relies on the World Health Organization and the International Consensus Classification of hematolymphoid tumors together with the recent cytogenetic advances. Here, we review the various chromosomal abnormalities that delineate well-established mature B-cell non-Hodgkin lymphoma entities as well as newly recognized genetic subtypes and provide cytogenetic guidelines for the diagnostic management of mature B-cell lymphomas.

Evaluation of Toll-like receptor and adaptor molecule polymorphisms for susceptibility to tuberculosis in a Colombian population.

Immunological studies have supported the idea that innate immunity is critical for the control of Mycobacterium tuberculosis (Mtb) infection in humans. Despite the overwhelming evidence showing the critical role of Toll-like receptors (TLRs) in the in vitro recognition of Mtb, the in vivo significance of individual TLRs has been more difficult to demonstrate consistently. We were interested in examining the role of genes of TLRs and molecules involved in their signalling cascades, and a case-control study was designed to test the association of polymorphisms of these innate immune genes with pulmonary tuberculosis (TB) in a Colombian population. In this study, we did not find an association with TLR2, TLR4, TLR9, MyD88 or MAL/TIRAP polymorphic variants. These findings suggest that those genes are not involved as risk factors for pulmonary TB in our population.

[Composite midfacial flap vascularized by the facial artery: a preliminary anatomic study]. / Lambeau composite médiofacial vascularisé par l'artère faciale: étude anatomique préliminaire.

INTRODUCTION: Extended facial tissue defects are difficult to reconstruct because of the anatomical and functional complexity of the area. Recently, composite facial allotransplantation was used for reconstruction. This could be performed because of specific facial blood supply and its facial and maxillary anastomoses. Could a composite naso-labio-mental flap rely on the sole blood supply of a facial artery anastomosis? We performed an anatomic study of a naso-labio-mental composite flap vascularized by the facial artery. MATERIAL AND METHOD: The study relied on arteriographies made on cadaveric heads and in vivo. The following data was analyzed: caliber of facial and maxillary arteries, terminal branch of facial arteries, and vascular territories. RESULTS: Sixteen facial arteries and six maxillary arteries were studied. The mean facial artery caliber was 2.06 mm (1-3.2mm). The facial artery ended in the nasal area in 68.8% of the cases. The latero-nasal artery was always present; it was a branch of the facial artery in 66.7% of cases. The two facial arteries, when injected bilaterally, always allowed complete facial composite flap circulation. The nasal territory of the flap was not opacified by the homolateral facial artery in 16.7% of the cases. DISCUSSION: Both facial artery anastomoses are recommended as blood supply for composite midfacial flaps. Preoperative imaging should be used systematically to assess the vascular network before harvesting.

The complex karyotype in hematological malignancies: a comprehensive overview by the Francophone Group of Hematological Cytogenetics (GFCH).

Karyotype complexity has major prognostic value in many malignancies. There is no consensus on the definition of a complex karyotype, and the prognostic impact of karyotype complexity differs from one disease to another. Due to the importance of the complex karyotype in the prognosis and treatment of several hematological diseases, the Francophone Group of Hematological Cytogenetics (Groupe Francophone de Cytogénétique Hématologique, GFCH) has developed an up-to-date, practical document for helping cytogeneticists to assess complex karyotypes in these hematological disorders. The evaluation of karyotype complexity is challenging, and it would be useful to have a consensus method for counting the number of chromosomal abnormalities (CAs). Although it is not possible to establish a single prognostic threshold for the number of CAs in all malignancies, a specific consensus prognostic cut-off must be defined for each individual disease. In order to standardize current cytogenetic practices and apply a single denomination, we suggest defining a low complex karyotype as having 3 CAs, an intermediate complex karyotype as having 4 CAs, and a highly complex karyotype as having 5 or more CAs.

Appraisal of the burden of genital warts from a healthcare and individual patient perspective.

OBJECTIVE: Worldwide, genital warts, caused by human papillomavirus (HPV) is a common, sexually transmitted disease. The overall disease management strategy for genital warts should be determined not only by the prevalence, but also by the impact of the disease on individuals and society. The purpose of this study was therefore to investigate the epidemiological, economic and quality of life (QoL) burden of genital warts. METHODS: A systematic literature review was conducted on the epidemiology, QoL and management cost of genital warts in the USA, UK and France, based on studies published between 1998 and 2008. Due to scarcity of data, all studies reporting standardized QoL assessments among patients with genital warts were utilized, regardless of country of origin. Original studies were preferred over information cited in review articles. RESULTS: Data from three countries suggest that genital warts occur in 0.06-0.23% of the population each year. Despite the fact that spontaneous remissions occur frequently (up to 40%), patients often prefer immediate treatment. While treatment can be costly in absolute terms (€163-510 per treatment episode), these costs are lower compared with other sexually transmitted infections (STIs). Modest reductions in QoL have been noted, which may be mitigated through adequate patient education and support. CONCLUSIONS: While genital warts are an inconvenience for many patients, the occurrence may be lower than often quoted in the literature, and the economic burden on society is less than for other prominent STIs. However, concerted efforts to establish improved data collection and surveillance systems are needed in order to accurately define the burden of genital warts on individuals and society.

[Tongue reconstruction with a bilateral infrahyoid flap innervated by Ansa Cervicalis after total glossectomy]. / Le lambeau infrahyoïdien bilatéral innervé par l'Ansa Cervicalis pour la reconstruction des glossectomies totales.

INTRODUCTION: Reconstruction after total glossectomy remains a functional challenge. It must provide a large volume to ensure adequate phonation and swallowing. We present the larynx sparing bilateral infrahyoid flap reconstruction procedure after total glossectomy. PATIENTS AND METHOD: Three patients managed for an epidermoid carcinoma of the tongue, classified T4N0, underwent total glossectomy. The tongue was reconstructed with a bilateral infrahyoid flap pedicled on two superior thyroid arteries and innervated by Ansa Cervicalis. RESULTS: Oral food intake was resumed after 8 to 20 days. No false route was observed. The muscular flap mobility was clinically satisfactory. It was assessed by EMG in one case. Esophageal transit confirmed the absence of stasis and false route for one patient. DISCUSSION: This short series proves the feasibility of bilateral innervated and pedicled infrahyoid flap procedure. It is an alternative to volumetric and functional reconstruction after total glossectomy. The indications are rare and restricted to patients without IIa nodal region invasion. Our results are still limited and need to be confirmed by a larger series and by a more systematic assessment.

[Empirical antibiotic therapy for urinary tract infection in children. Analysis of three hundred patients admitted to a general hospital]. / Antibiothérapie empirique dans les infections urinaires de l'enfant. Analyse de trois cents patients admis dans un hôpital général.

For more than 25 years, treatment of acute pyelonephritis in children has been the subject of debates. Recent publications (including of Cochrane database review) let think that oral antibiotics could be as safe as intravenous treatement at least regarding the major concerns of urinary infection: renal scaring, time to defervescence and sterilization of urine at 72 hours. To investigate if such a protocol could be applied in our country, we first determine the rate of bacterial resistance to oral antibiotics commercially available in Belgium. Antibiograms of 191 outpatients with a diagnosis of pyelonephritis show that neither amoxicillin, amoxicillin/clavulanate nor trimethoprim/sulphamethoxazol can be recommended as an empiric treatment of febrile urinary infection among children in our region. Only 80% of bacterial strains were sensitive to amoxicillin/clavulanate, a level far below the rate reported in literature in favour of oral treatment of acute pyelonephritis (> 90%). Cefuroxime seems to be a better candidate as first line therapy, however no clinical study supports its use.

A multirecurrent ameloblastoma metastatic to the lung.

INTRODUCTION: The ameloblastoma is a rare tumor of odontogenic epithelial origin. It is a neoplasm in which ameloblastic features are revealed by the primary growth in jaws and by any metastatic growth. Recurrences are usually local and distant metastases are rare. We present a case of a multirecurrent ameloblastoma of the mandible metastatic to the lung. OBSERVATION: We present a case of a mandibular malignant ameloblastoma in a 42-year old man with widespread pulmonary metastases. Some of these lesions were treated surgically. DISCUSSION: Ameloblastoma metastasis often occurs in the lung. The curative treatment is surgical. The results of palliative chemotherapy and radiotherapy are not always efficient.

Genetic variants in the region harbouring IL2/IL21 associated with ulcerative colitis.

OBJECTIVES: Genetic susceptibility is known to play a large part in the predisposition to the inflammatory bowel diseases (IBDs) known as Crohn's disease (CD) and ulcerative colitis (UC). The IL2/IL21 locus on 4q27 is known to be a common risk locus for inflammatory disease (shown in coeliac disease, type 1 diabetes, rheumatoid arthritis, systemic lupus erythematosus and psoriasis), while the roles that interleukin 2 (IL2) and IL21 play in the immune response also make them attractive candidates for IBD. The objective of this study was to test for association between the IL2/IL21 locus and the IBDs. METHODS: The four single nucleotide polymorphisms (SNPs) in the IL2/IL21 locus most associated with coeliac disease were genotyped in 1590 subjects with IBD and 929 controls from The Netherlands, and then replicated in a North American cohort (2387 cases and 1266 controls) and an Italian cohort (805 cases and 421 controls), yielding a total of 4782 cases (3194 UC, 1588 CD) and 2616 controls. Allelic association testing and a pooled analysis using a Cochran-Mantel-Haenszel test were performed. RESULTS: All four SNPs were strongly associated with UC in all three cohorts and reached genome-wide significance in the pooled analysis (rs13151961 p = 1.35 x 10(-10), rs13119723 p = 8.60 x 10(-8), rs6840978 p = 3.0 7x 10(-8), rs6822844 p = 2.77 x 10(-9)). A moderate association with CD was also found in the pooled analysis (p value range 0.0016-9.86 x 10(-5)). CONCLUSIONS: A strong association for the IL2/IL21 locus with UC was found, which also confirms it as a general susceptibility locus for inflammatory disease.

The importance of using 3D ultrasound during pelvic organ prolapse surgery in relation to pre- and post-operative quality of life questionnaires.

AIM: The main aim of this study is to evaluate the interest of three-dimensional ultrasound perineal in the measurement of the levator hiatus area as an objective reflection of the surgical correction of pelvic organ prolapse (POP). Our hypothesis is that POP surgery decreases the size of the levator hiatus area. MATERIALS AND METHODS: A longitudinal and prospective study was conducted between April and July 2017 in the Department of Gynaecology & Obstetrics at University Hospital of Angers. Surgery was performed either by laparoscopy (sacrocolpopexy) or vaginal surgery (with or without the use of mesh). All patients were handed an information letter and signed an informed consent before being included in the study. A questionnaire was fullfilled before and one month after surgery. A clinical evaluation using the simplified POP-Q classification and a perineal 3D ultrasound were carried out before and after surgery by the same professional. The levator hiatus area was assessed before and after surgery in order to evaluate the impact of surgery on the levator hiatus area. Simplified POP-Q measurements and responses to PFDI-20 and PFDI-7 questionnaires were also collected. RESULTS: A total of 18 patients were included in the study and four were excluded. Seven underwent laparoscopic surgery and seven underwent vaginal surgery. The levator hiatus area decreased substantially from 20.87 to 16.55cm2 on mean (p=0.0001) at rest. Regarding patient satisfaction, the PFDI-20 score improved after surgery from 89.36 to 37.87 on mean (p=0.006), but the PFIQ-7 score did not reveal any significant changes (p=0.096). For the clinical examination, we used the simplified POP-Q with Ba measurement from 2.3 to -1.92cm (p=0.005) or Bp from -1.5 to -2.46cm, which is not a significant change (p=0.14). Points C (or D in cases with a history of hysterectomy) changed from -3.1 to -6.15cm (p=0.03). CONCLUSION: The levator hiatus area seems to decrease after POP surgery. 3D ultrasound seems a new and complementary procedure that allowed to evaluate objectively the levator hiatus area and thus the clinical findings of the surgery.

Immune checkpoint inhibitors versus second line chemotherapy for patients with lung cancer refractory to first line chemotherapy.

PURPOSE: Anti Programmed Death-ligand (PD1/PD-L1) directed immune-checkpoint-inhibitors (ICI) are widely used to treat patients with advanced non-small cell lung cancer (NSCLC) who progress after first line chemotherapy. The best strategy after early progression under first line has not been specifically studied. PATIENTS AND METHODS: We conducted a multicenter, retrospective study including all consecutive NSCLC patients progressing within the first 3 months following introduction of first-line chemotherapy and being treated with second line ICI monotherapy or chemotherapy between March 2010 and November 2017. We analysed the clinicopathological data and outcome under second line chemotherapy vs. second line ICI: objective response rate (ORR), progression-free survival (PFS), overall survival (OS. RESULTS: We identified 176 patients with refractory disease, 99 who received subsequent immunotherapy and 77 undergoing chemotherapy. The 2 populations were comparable regarding the main prognostic criteria, median age was 60, main histology was adenocarcimoma (68.2%). PFS was not significantly different between both treatments 1.9 [1.8-2.1] versus 1.6 month [1.4-2.0] (P=0.125). Compared to chemotherapy, ICI treated patients had a superior OS (P=0.03) (Median [95% CI] OS 4.6 [2.8-6.7] versus 4.2 months [3.4-5.9] and a non-significant improvement in ORR (17.2% versus 7.9%, respectively, P=0.072). Poor performance status (ECOG PS≥2) and a higher number of metastatic sites (≥3) were associated with poorer prognosis. KRAS-mutated patients did not seem to benefit more from ICI than chemotherapy. CONCLUSIONS: ICI appears to be the preferred second-line treatment for patients who are refractory to first line chemotherapy.

[276 cases of horizontal infrahyoid myocutaneous flap]. / Le lambeau musculocutané infrahyoïdien à palette cutanée horizontale : à propos de 276 cas.

INTRODUCTION: The infrahyoid myocutaneous flap was described by Wang et al. in 1986. The horizontal design of the skin paddle is a modification of this technique allowing for a smaller scar. We have been systematically using this modified technique for 10 years. We had for aim to describe the interest of the horizontal infrahyoid myocutaneous flap for cervicofacial carcinology. PATIENTS AND METHODS: A horizontal infrahyoid myocutaneous flap procedure was performed in 276 cervicofacial carcinology patients for lesions of the mouth floor, the mandibular gum, the oropharynx and the tongue between March 1997 and March 2007. RESULTS: No complications were observed in 252 patients. No patient presented with total flap necrosis. DISCUSSION: Modifying the infrahyoid myocutaneous flap technique with a horizontal design of the skin paddle does not modify the reliability of the flap and prevents more extensive scars. The main indications of this technique are defects of the mouth floor, the tongue and the oropharynx.
