Abstract

Purpose: To study the treatment and outcomes of children with retinoblastoma (RB) with extraocular tumor extension (RB-EOE) and compare them with RB without extraocular tumor extension (RB-w/o-EOE). Design: Multicenter intercontinental collaborative prospective study from 2017 to 2020. RB-EOE cases included those with overt orbital tumor extension in treatment-naive patients. Cases with microscopic orbital extension detected postenucleation were excluded from the study. Participants: A total of 319 children with RB-EOE and 3116 children with RB-w/o-EOE. Intervention: Chemotherapy, enucleation, exenteration, radiotherapy. Main Outcome Measures: Systemic metastasis and death. Results: Of the 3435 RB patients included in this study, 309 (9%) were from low-income countries (LIC), 1448 (42%) from lower-middle income, 1012 (29%) from upper-middle income, and 666 (19%) patients from high-income countries. There was an inverse relationship between the percentage of RB-EOE and national income level, with 96 (31%) patients from LIC, 197 (6%) lower-middle income, 20 (2%) upper-middle income, and 6 (1%) patients from high-income countries (P = 0.0001). The outcomes were statistically significant for RB-EOE compared with RB-w/o-EOE: systemic metastasis (32% vs. 4% respectively; P = 0.0001) and metastasis-related death (63% vs. 6% respectively; P = 0.0001). Multimodal treatment was the most common form of treatment (n = 177; 54%) for RB-EOE, with most cases undergoing a combination of intravenous chemotherapy and enucleation (n = 97; 30%). Adjuvant external beam radiotherapy (EBRT) after surgery (enucleation/orbital exenteration) was given in only 68 (21%) cases. Kaplan–Meier analysis for systemic metastasis and metastasis-related death in RB-EOE was 28% and 57% at 1 year, 29% and 60% at 2 years, and 29% and 61% at 3 years, respectively. Cox regression analysis revealed that the risk of death from RB-EOE was greater in patients aged >4 years than

Abstract

Introduction:Pulmonary embolism is the sudden obliteration (total or partial)of the trunk of the pulmonary artery or one of its branches by a circulating foreign body, most often fibrino-cruoric. Objectives:To study the place of chest CT angiography in the diagnosis of pulmonary embolism Material And Method:This was a descriptive prospective study from February 1, 2020 to January 31, 2021 taking into account all patients referred during this period for clinical suspicion of pulmonary embolism to the medical clinic Marie Curie et les Etoiles. The examinations were performed with a GE 16-bar scanner in helical mode with and without injection of iodinated contrast product by an automatic injector. Results:We diagnosed 43 pulmonary embolisms out of 327 thoracic CT angiography performed by highlighting hypodense gaps inside one or more pulmonary arteries as well as certain branches of division and the sudden interruption of the opacification of certain distal arteries. The prevalence of pulmonary embolism was 13.15%. The female sex predominated with 52% (n=22) and the sex ratio was 1.16. The average age of patients in our series was 45 years with extremes (25 to 85 years). The age group of 41-50 years waspredominant. Dyspnea and chest pain were the most frequent clinical information with44.18% and 18.60% respectively. The seat of the pulmonary embolism concerned the right pulmonary arteries and the seat of the pulmonary embolism concerned the right and left pulmonary arteries in 60.46% and the right side was the most affected. Chronic Obstructive Pulmonary Disease (COPD) Pleurisy and Covid-19 were the lesions most associated with pulmonaryembolism (48.83%, 18.60% and 16.28%) Conclusion:Pulmonary embolism is a serious and life-threatening pathology. Its diagnosis of certainty is made with the thoracic CT angiography, the realization of which must not suffer from any delay. &nbsp

Abstract

Aims: To describe the clinical and evolutionary aspects of the primary closure of exstrophy at the CHU Gabriel Touré. Materials and Methods: This was a retrospective and prospective study carried out from January 2014 to December 2019 in all the children admitted and operated on for bladder exstrophy at the CHU Gabriel Touré. Results: We collected 35 cases of exstrophy, ie25 boys and 10 girls. The mean age at diagnosis was 4.8 months. The bladder plate was both normal and budded, ie 28.6% of cases. Plaque infection was found in 45.7%. A malformation was associated in 34.3% of cases. Primary plaque closure was achieved in all of our patients. Postoperative morbidity was 28.6% of cases and mortality 11.4% of cases. Conclusion: Bladder exstrophy is a rare malformation of the urogenital sphere, its management is complex and its mortality is not null. [ABSTRACT FROM AUTHOR]

Abstract

Background. Posterior urethral valves are membranous folds that obstruct urine output. The treatment is multidisciplinary. Aim: To describe the results of valves destruction using the Fogarty catheter. Patients and Methods: This was a retrospective and descriptive study ranging from January 1st, 2014 to December 31th, 2020 in all boys admitted for posterior urethral valves confirmed by retrograde urethrocystography and treated in the department of pediatric surgery by Fogarty valve destruction technique. After the treatment the patients were followed for a period of 6 months with an ultrasound and serum creatinine level. The chi square test was used to discuss the results with a significance threshold of p≤ 0.05 Results: In 7 years we managed 82 cases of posterior urethral valves. The average age of our patients was 9.1± 14.73 months (1 day and 72 months). The mean serum creatinine level was 97.38 ±133.35 μmol/L. A vesico-ureteral reflux was associated with the urethral valves in 29.3% and a vesical diverticulum in 32.9%. Bilateral ureterohydronephrosis was noted in 61%. After 3 months of follow-up the serum creatinine level remained high in 13.4% and a vesico-ureteral reflux persisted in 18.3% of cases. The mean time to valve destruction was 57 ±4.15 days (1 and 660 days). During six months of survey our success rate was 70.7%. Urinary tract infection was noted in 19.5%, and the mortality rate was 9.76%. Conclusion: Although an alternative method, valves destruction technique by the Fogarty probe can give satisfactory results. The rapid diagnosis and treatment of valves will help to improve the prognosis.

Abstract

BackgroundThe travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe.MethodsA cross-sectional analysis including 518 treatment-naïve patients with retinoblastoma residing in 40 European countries and 1024 treatment-naïve patients with retinoblastoma residing in 43 African countries.ResultsCapture rate was 42.2% of expected patients from Africa and 108.8% from Europe. African patients were older (95% CI −12.4 to −5.4, pConclusionsFewer than half the expected number of patients with retinoblastoma presented to African referral centres in 2017, suggesting poor awareness or other barriers to access. Despite the relatively shorter distance travelled by African patients, they presented with later-stage disease. Health education about retinoblastoma is needed for carers and health workers in Africa in order to increase capture rate and promote early referral.

Abstract

L’ostéo-arthrite est une inflammation infectieuse métaphysaire et épiphysaire avec un épanchement intra-articulaire purulent. Il s’agit d’une urgence diagnostique et thérapeutique.Nous décrivons les aspects épidémio-cliniques, thérapeutiques et évolutifs des ostéo-arthrites de l’enfant dans un contexte de diagnostic tardif au centre hospitalier et universitaire Gabriel Touré de Bamako, Mali.Il s’agissait d’une étude rétrospective et prospective (rétrospective=1an, prospective= 1 an) sur une période de 2 ans allant du 1er janvier 2014 au 31 Décembre 2016.En deux ans, nous avons colligé 40 cas d’ostéoarthrite; ce qui a représenté une fréquence hospitalière de 1,4%. L’âge moyen des patients était de 6,35 ans avec des extrêmes de 28 jours et 14 ans. La sex-ratio était de 1,6. La douleur était le motif de consultation le plus fréquent. La porte d’entrée a été trouvée dans 67,5% des cas. Nous avions noté 27 cas d’hémoglobinopathie. Le genou était l’articulation la plus atteinte (42,5%). La culture bactériologique était positive dans 80% des cas et le germe le plus isolé était le Staphylococcus aureus dans 42,5% des cas. Nous avons eu recours à la chirurgie dans 75% des cas. L’évolution était favorable dans 85% des cas.L’ostéo-arthrite est une pathologie rare dans notre pratique. La prise en charge rapide et correcte permet d’obtenir des résultats satisfaisants. Le dépistage des hémoglobinopathies est important pour prévenir voir éviter les séquelles invalidantes.Mots clés: Ostéo-arthrite, Enfant, Bamako, MaliEnglish AbstractSeptic arthritis which results from the presence of purulent effusion in the joint space can co-exist with osteomyelitis involving the epiphysis and metaphysis in childre.

Abstract

Ce travail a pour objectif d’évaluer les résultats de l’embrochage centromédullaire élastique stable (ECMES) dans les fractures diaphysaires du fémur chez l’enfant. Il s’agissait d’une étude prospective qui s’est déroulée de Janvier 2013 à Décembre 2013 dans le service de Chirurgie Pédiatrique du CHU Gabriel TOURE portant sur tous les enfants âgés de 7 à 15ans et présentant une fracture diaphysaire du fémur et dont le délai de consultation n’excédait pas 21 jours. En guise de résultat, nous avons opéré 15 cas de fracture diaphysaire du fémur soit 5% des fractures opérées (300 cas). L’effectif était composé de 8 filles contre 7 garçons soit un sexe ratio de 0,88. L’âge moyen de nos patients était de 10,1 ans avec des extrêmes de 7 et 14 ans. L’étiologie la plus fréquente était les accidents de la voie publique (73,3%). Le choc était direct dans 86,6%. Le fémur droit était atteint dans 53%. Le délai moyen de consultation était de 6 heures. Le trait de fracture était transverse dans 80% et oblique dans 20%. Le siège le plus fréquent était le 1/3 moyen de la diaphyse fémorale. Le délai moyen de prise en charge était de 3 jours.Nous avons procédé à un embrochage centromédullaire élastique stable ascendant dans 86,6%. Les résultats ont été évalués avec un recul moyen de 5 mois, ils étaient excellents dans 93,3% et un seul cas de raideur en extension de 10 degrés. En conclusion, l’ECMES est une technique particulièrement adaptée au traitement chirurgical des fractures diaphysaires du fémur de l’enfant d’âge scolaire. Bien pratiqué, il donne de bons résultats. Le traitement orthopédique doit rester de règle mais ceci n’est plus aussi formel qu’avant.Mots clés: fracture, diaphyse fémorale, grand enfant, ECMESEnglish AbstractThe objective of this work is to evaluate the results of stable elastic centro medullary insertion (ECMES) in diaphyseal femoral fractures in children. This was a prospective study that took place from January 2013 to December 2013 in the Department of Pediatric Surgery of CHU Gabriel TOURE, covering all children aged 7 to 15 years and presenting a diaphyseal fracture of the femur and whose consultation period did not exceed 21 days. We performed 15 cases of diaphyseal fracture of the femur or 5% of the fractures performed (300 cases). The number was 8 girls versus 7 boys, a sex ratio of 0.88. The average age of our patients was 10.1 years with extremes of 7 and 14 years. The most frequent etiology was road traffic accidents (73.3%). The shock was direct in 86.6%. The right femur was reached in 53%. The average time to consult was 6 hours. The fracture line was transverse in 80% and oblique in 20%. The most frequent seat was the middle 1/3 of the femoral diaphysis. The average waiting time was 3 days. We performed a stable elastic centro medullary insertion in 86.6%. The results were evaluated with an average follow-up of 5 months, excellent in 93.3% and a single case of stiffness in extension of 10 degrees. To conclude, stable elastic centro medullary insertion is a technique particularly adapted to the surgical treatment of diaphyseal fractures of the femur of the school-aged child. Well done, it gives good results. Orthopedic treatment must remain the rule, but this is no longer as formal as before.Keywords: fracture, femoral diaphysis, large child, ECMES

Abstract

Les urgences chirurgicales sont des affections graves avec une mortalité élevée dans les pays en développement. Cette mortalité varie de 20 à 70% [1]. L’objectif était d’étudier les facteurs ayant influencé la mortalité des urgences chirurgicales néonatales. Il s’agissait d’une étude rétrospective réalisée sur une période de 5 ans du 1er janvier 2010 au 31 décembre 2014. Elle a porté sur tous les nouveaux- nés de 0 à 21 jours pris en charge pour urgences chirurgicales viscérales au CHU Gabriel Touré. Les urgences neurochirurgicales et traumatologiques n’ont pas été inclues dans l’étude. Nous avons enregistré, en guise de résultats, 4079 hospitalisations en néonatologie parmi lesquelles 357 cas d’urgences chirurgicales. Ce qui a représenté 8,7 %. L’effectif comprenait 212 garçons et 145 filles. Le sex-ratio était de 1,46. L’âge moyen des patients était de 5,7 ± 0,5 jours (extrêmes : 2 h et 21 jours). Le délai moyen de consultation était de 5,4 jours (extrêmes : 2 h et 21 jours). L’atrésie de l’oesophage et le laparoschisis avaient des taux de mortalité respectifs de 91 et 100%. Une pathologie associée était notée chez 50,4% de nos patients.La colostomie était la méthode chirurgicale la plus fréquente. La mortalité post-opératoire était de 42,3%. Les facteurs incriminés à la mortalité étaient l’âge, l’hypotrophie, la présence de malformations associées, la situation socio-économique des parents, leur niveau de scolarisation et la survenue de complications post-opératoires (p < 0.05). Le sexe et le délai de prise en charge n’étaient pas déterminants. En somme, la mortalité des urgences chirurgicales néonatales dans notre pays reste très élevée et multifactorielle.Mots-clés: Urgences chirurgicales, néonatale, mortalitéEnglish AbstractSurgical neonatal emergencies have grave consequences with a high mortality rate in developing countries. This mortality varies from 20 to 70% [1]. All this was about studying the factors influencing the mortality of surgical neonatal emergencies. It was a retrospective study done during 5 years from January, 1st 2010 to December 31th 2014. It includes all new-borns aged from 0-21 days admitted in surgical emergencies of Gabriel Touré teaching hospital. Neurosurgical and trauma emergencies were not included in the study. As results, we had 4079 new-borns admitted in neonatology among which 357 were cases of surgical emergencies (8.7%). There were 212 boys and 145 girls. Sexratio was 1.46. Mean age was 5.7±0.5 days. Mean time limit of consultation was 5.4 days. The most lethal diseases were oesophageal atresia and gastroschisis with mortality rates of 91 and 100% respectively. An associated disease was noted in 50.4%. Colostomy was the most frequent surgical intervention. Postoperative mortality rate was 42.3%. This mortality rate was influenced by patient’s age, underweight, presence of associated malformations, parent’s socio-economic conditions and education level; and post-operative complications (p< 0.05). Patients’ sex, consultation delay was not significant. To conclude, the rate of mortality of surgical neonatal emergencies in our country remains high and multifactorial.Keywords: Surgical emergencies, neonate, mortality

Abstract

The In-vitro protein digestibility, protein nutritional quality and functional characteristics (protein solubility, water/oil binding capacity, emulsifying capacity and foaming capacity) of gingerbread plum and peanut seed flour were studied. Among the nutritional parameters, the proportion of essential amino acids to total amino acids (E/T), amino acid scores (AAS) and protein efficiency ratio (PER) were studied. Defatted gingerbread plum seed meal (DGPSM) showed a high nutritional quality with PER and AAS values of 2.35 and 65.53 respectively. The solubility profile of DGPSM was similar to that of defatted peanut meal (DPM), with minimum solubility observed at pH 4 and maximum solubility at pH 10 and higher. Water and oil holding capacities were 3.01 and 3.12; 2.96 and 3.11 g/g for DGPSM and DPM respectively. DGPSM showed good foaming capacity (145 mL /100 mL) and stability (110 mL /100 mL) even after 60 min at room temperature. The emulsifying capacity of DGPSM was 29%. Bulk densities were 0.30 and 0.28 g/mL for DGPSM and DPM respectively. Finally, DGPSM was easily hydrolyzed by trypsin in vitro. These results show that DGPSM has functional properties that may find applications in the food industry.La digestibilidad de proteínas in vitro, la calidad nutricional de proteínas y las características funcionales (solubilidad de proteínas, capacidad de enlace agua/aceite, capacidad emulsionante y capacidad espumante) de harina de semillas de ciruela de pan de jengibre y de cacahuete fueron estudiadas. Entre los parámetros nutricionales, la relación aminoácidos esenciales/aminoácidos totales (E/T), el perfil de aminoácidos (AAS) y el coeficiente de eficacia proteica (PER) fueron estudiadas. Harina de semillas de ciruela de pan de jengibre (DGPSM) mostraron una alta calidad nutricional con unos valores de PER y de AAS de 2.35 y 65.53 respectivamente. El perfil de solubilidad de DGPSM fue similar al de la harina desengrasada de cacahuete (DPM), con una mínima solubilidad observada a pH 4 y un máximo de solubilidad a pH 10 y superior. Las capacidad de retención de agua y de aceite fueron 3.01 y 3.12; 2.96 y 3.11 g/g para DGPSM y DPM respectivamente. DGPSM mostró una buena capacidad espumante (145 mL /100 mL) and estabilidad (110 mL /100 mL) incluso después de 60 min a temperatura ambiente. La capacidad emulsionante de DGPSM fue del 29%. Las densidades fueron 0.30 y 0.28 g/ml para DGPSM y DPM respectivamente. Por último, DGPSM fue fácilmente hidrolizado por tripsina in vitro. Estos resultados mostraron que DGPSM tienen propiedades funcionales que pueden encontrar aplicación en la industria alimentaria.

Abstract

A study of the validation and calibration process for integrated water vapor (IWV) measurements derived from sun radiometry at the 940-nm solar absorption channel employed in the Aerosol Robotic Network (AERONET) Aerosol Canada (AEROCAN) is presented. The sun radiometer data are compared with GPS meteorology records used as a reference. Three Canadian sites from different climatic regimes covering the period 2000–04 are considered. The observations from five different sun radiometers (IWV-SUN) were processed using the initial AERONET IWV retrieval procedure (V1) whereas GPS-derived IWV (IWV-GPS) was retrieved using “GPSpace” software developed by the Geodetic Survey division of Natural Resources Canada. A sensitivity study is carried out to highlight the influence of both central wavelength and signal amplitude on the 940-nm filter characteristics, which are instrument dependent and can drift due to aging. The comparison between IWV-SUN (V1) and IWV-GPS shows an average rmse of 0.23 ± 0.11 g cm−2 (22%) and a mean bias of −0.09 ± 0.16 g cm−2 (9%). Furthermore, it is shown that the use of GPS for determining the 940-nm channel calibration constants for the solar radiometers improves IWV retrievals (rmse reduced by about 35% and bias by a factor of 3–10) without any knowledge of the 940-nm filter characteristics. These results are discussed within the context of the new AERONET IWV processing procedure (V2), which accounts for solar 940-nm region filter characteristics. The GPS receiver technique appears to be a powerful calibration tool because of its continuous observation capability, its robustness, and its operational simplicity.

Abstract

BackgroundThe travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, the most common childhood eye cancer. We aimed to investigate the travel burden and its impact on clinical presentation in a large sample of patients with retinoblastoma from Africa and Europe.MethodsA cross-sectional analysis including 518 treatment-nai¨ve patients with retinoblastoma residing in 40 European countries and 1024 treatment-nai¨ve patients with retinoblastoma residing in 43 African countries.ResultsCapture rate was 42.2% of expected patients from Africa and 108.8% from Europe. African patients were older (95% CI −12.4 to −5.4, p<0.001), had fewer cases of familial retinoblastoma (95% CI 2.0 to 5.3, p<0.001) and presented with more advanced disease (95% CI 6.0 to 9.8, p<0.001); 43.4% and 15.4% of Africans had extraocular retinoblastoma and distant metastasis at the time of diagnosis, respectively, compared to 2.9% and 1.0% of the Europeans. To reach a retinoblastoma centre, European patients travelled 421.8 km compared to Africans who travelled 185.7 km (p<0.001). On regression analysis, lower-national income level, African residence and older age (p<0.001), but not travel distance (p=0.19), were risk factors for advanced disease.ConclusionsFewer than half the expected number of patients with retinoblastoma presented to African referral centres in 2017, suggesting poor awareness or other barriers to access. Despite the relatively shorter distance travelled by African patients, they presented with later-stage disease. Health education about retinoblastoma is needed for carers and health workers in Africa in order to increase capture rate and promote early referral.

Abstract

IMPORTANCE: Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child’s life and vision. However, anecdotal evidence suggests that many children across the world are diagnosed late. To our knowledge, the clinical presentation of retinoblastoma has never been assessed on a global scale. OBJECTIVES: To report the retinoblastoma stage at diagnosis in patients across the world during a single year, to investigate associations between clinical variables and national income level, and to investigate risk factors for advanced disease at diagnosis. DESIGN, SETTING, AND PARTICIPANTS: A total of 278 retinoblastoma treatment centers were recruited from June 2017 through December 2018 to participate in a cross-sectional analysis of treatment-naive patients with retinoblastoma who were diagnosed in 2017. MAIN OUTCOMES AND MEASURES: Age at presentation, proportion of familial history of retinoblastoma, and tumor stage and metastasis. RESULTS: The cohort included 4351 new patients from 153 countries; the median age at diagnosis was 30.5 (interquartile range, 18.3-45.9) months, and 1976 patients (45.4%) were female. Most patients (n = 3685 [84.7%]) were from low- and middle-income countries (LMICs). Globally, the most common indication for referral was leukocoria (n = 2638 [62.8%]), followed by strabismus (n = 429 [10.2%]) and proptosis (n = 309 [7.4%]). Patients from high-income countries (HICs) were diagnosed at a median age of 14.1 months, with 656 of 666 (98.5%) patients having intraocular retinoblastoma and 2 (0.3%) having metastasis. Patients from low-income countries were diagnosed at a median age of 30.5 months, with 256 of 521 (49.1%) having extraocular retinoblastoma and 94 of 498 (18.9%) having metastasis. Lower national income level was associated with older presentation age, higher proportion of locally advanced disease and distant metastasis, and smaller proportion of familial history of retinoblastoma. Advanced disease at diagnosis was more common in LMICs even after adjusting for age (odds ratio for low-income countries vs upper-middle–income countries and HICs, 17.92 [95% CI, 12.94-24.80], and for lower-middle–income countries vs upper-middle–income countries and HICs, 5.74 [95% CI, 4.30-7.68]). CONCLUSIONS AND RELEVANCE: This study is estimated to have included more than half of all new retinoblastoma cases worldwide in 2017. Children from LMICs, where the main global retinoblastoma burden lies, presented at an older age with more advanced disease and demonstrated a smaller proportion of familial history of retinoblastoma, likely because many do not reach a childbearing age. Given that retinoblastoma is curable, these data are concerning and mandate intervention at national and international levels. Further studies are needed to investigate factors, other than age at presentation, that may be associated with advanced disease in LMICs.

Abstract

Objectives: to identify the main causative agents of infection associated with care and their susceptibility to antibiotics used and to identify risk factors for care-associated infection. Material and methods: This was a cross-sectional study with prospective data collection, conducted from 1 November 2016 to 1 April 2017 among all children admitted to the pediatric surgery department. Nonconsenting parents and cases of necrosectomy were included in this study. Results: Our study involved 200 patients, 30 of whom presented a care-associated infection (15% infection rate). The average age of patients with infection was 56.33 ± 48.66 months (1 and 180 months). The main pathogens responsible for infection of the operative site were: Escherischia coli (4 cases), Acinetobacterbaumanii (3 cases), Klebsiella pneumoniae (2 cases), Staphylococcus aureus (2 cases), Enterobacter cloacae (1case), Pseudomonas aeruginosa (1 case) and Enterobacter faecalis (1 case). In the burned patients, the organisms found were: Acinetobacter baumanii (7 cases), Klebsiella pneumoniae (6 cases), Staphylococcus aureus (6 cases), Escherischia coli (4 cases), Pseudomonas aeruginosa (2 cases) and Enterobacter faecalis (2 cases). Escherichia coli was noted in urinary tract infection. Antibiotics tested were amoxicillin, amoxicillin-clavulanic acid, ceftriaxone, imipenem, gentamicin and ciprofloxacin. The mode of recruitment and the duration of hospitalization were the risk factors noted. Conclusion: The infection associated with care is a frequent occurrence in our practice. These infections mainly occur at the operating sites. The germs found were: Acinetobacter, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus. They are all sensitive to imipenem and resistant to amoxicillin. The infection remains formidable in health care. It is essential to give special attention to the prevention of infectious risk, especially in the surgical setting. [ABSTRACT FROM AUTHOR]

Abstract

This study investigates the utility of the land degradation index (LDI) approach to express land degradation in a small Mediterranean watershed with enhanced thematic mapper plus (ETM+) data. The LDI is based on the concept of the soil line, and was elaborated from advanced spaceborne thermal emission and reflection radiometer (ASTER) sensor data and field spectra measurements. The implementation of the LDI index uses all the bands of the spectral domain in the visible, near infrared (NIR), and short wave infrared (SWIR). Field measurements were carried out in the Saboun experimental basin located in a marl soil region of the Moroccan western Rif for which soil, hydrological, and erosion databases were readily available. The present study provided the opportunity for studying and characterizing the state of soil degradation using the LDI. Our results show the interest of the use of the LDI with ASTER data to study or to map land degradation. It provides more accurate results (Kappa = 0,79) when compared w...

Abstract

Flagrant soil erosion in Morocco is an alarming sign of soil degradation. Due to the considerable costs of detailed ground surveys of this phenomenon, remote sensing is an appropriate alternative for analyzing and evaluating the risks of the expansion of soil degradation. In this paper, we characterize the state of land degradation in a small Mediterranean watershed using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data and ground-based spectroradiometric measurements. The two visible, the near-infrared and six shortwave infrared bands of the above sensor were calibrated using ground measurements of the spectral reflectance. Field measurements were carried out in the Saboun experimental basin located in the marl soil region of the Moroccan western Rif. The study leads to the development and evaluation of a new spectral approach to express land degradation. This index called Land degradation index (LDI) is based on the concept of the soil line derived from spectroradiometric ground measurements. In this study, we compare LDI and the spectral angle mapping (SAM) approaches to assess and map land degradation. Results show that LDI provides more accurate results for mapping land degradation (Kappa = 0.79) when compared to the SAM method (Kappa = 0.61). Validation and evaluation of the results are based on the thematic maps derived from the ground data (organic matter, clay, silt and sand) by kriging, DEM, slope gradient and photointerpretation.

Abstract

Ground‐based sunphotometry measurements acquired under clear sky conditions can be used to investigate atmospheric aerosol optical properties. Such measurements are not only important in their own right as a technique for monitoring generic aerosol dynamics, but also represent a direct means of evaluating the contribution of aerosol induced radiative forcing in the modelling of climate change. In this paper we analyze derived aerosol optical properties using datasets from the Canadian AEROCAN (AERosol CANada) sunphotometer network. The AEROCAN network currently includes eight sunphotometers distributed across Canada at sites chosen in order to obtain a diverse sampling of continental, maritime and arctic aerosols. Some of these sites have been operational since 1993 as part of the Boreal Ecosystem‐Atmosphere Study (BOREAS). These instruments permit standard and automatic multi‐wavelength measurements of solar extinction radiance centred on the solar disk as well as sky radiance scans off the sola...

Abstract

The closure anomalies of the peritoneal-vaginal canal include several clinical entities, which are at the origin of various symptomatology. Objective: To study the anatomo-clinical and therapeutic aspects of pathologies of the peritoneal-vaginal canal. Materials and method: This was a prospective study from January 1st to December 31st, 2015 carried out in the pediatric surgery department of University Hospital Gabriel Touré. It covered all children aged 0-15 years old with a pathology of the peritonealvaginal canal operating in the department during the study period. This study did not include cases that were not operated on or not seen during the study period. Results: During the study period, 2,699 children were treated in pediatric surgery, of which 150 cases of pathology of the peritonealvaginal canal had a hospital frequency of 5.5%. The average age was 3.25 ± 9.63 years. The sex ratio was 14. The reason for consultation was intermittent or permanent inguinal or inguino-scrotal swelling in all children. The pathology was discovered by the parents during the pushing efforts in 46.7%. Inguino-scrotal swelling was found on physical examination in 40% of cases. The right side was reached in 60% of the cases. Hernia accounted for 80.6% of these pathologies. We recorded 31 cases of strangulation and 11 cases of craze. Immediate operative follow-up was simple in 92% of patients. This rate was 96% after 6 months. Conclusion: Pathologies of the peritoneal-vaginal canal are very common in pediatric surgical practice. The first place of these pathologies is occupied by hernia. They preferentially affect male infants. [ABSTRACT FROM AUTHOR]

Abstract

Heat shock protein 10 (Hsp10) in eukaryotes, originally identified as a mitochondrial chaperone, now is also known to be present in cytosol, cell surface, extracellular space and peripheral blood. Functionally besides participating in mitochondrial protein folding in association with Hsp60, Hsp10 appears to be related to pregnancy, cancer and autoimmune inhibition. Hsp10 can be released to peripheral blood at very early time point of pregnancy and given another name called early pregnancy factor (EPF), which seems to play a critical role in developing a pregnant niche. In malignant disorders, Hsp10 is usually abnormally expressed in the cytosol of malignant cells and further released to extracellular space, resulting in tumor-promoting effect from various aspects. Furthermore, distinct from other heat shock protein members, whose soluble form is recognized as danger signal by immune cells and triggers immune responses, Hsp10 after release, however, is designed to be an inhibitory signal by limiting immune response. This review discusses how Hsp10 participates in various physiological and pathological processes from basic protein molecule folding to pregnancy, cancer and autoimmune diseases, and emphasizes how important the location is for the function exertion of a molecule.

Abstract

Spatial remote sensing atmospheric correction algorithms validation remains a challenge particulary over land and coastal environment. To assess this type of algorithm in the case of MERIS scheme, we propose a methodology based on the use of in-situ extinction and sky measurements from the world-wide Sun radiometer network AERONET. The spectral dependency in the blue and red derived from the extinction measurements is used to parameterize an aerosol model defined by the Jung power law size distribution in a first step and a chemical composition represented by a refractive index. This model is used to compute the phase function, a main input to a radiative transfer code (successive order of diffusion based) that allows to simulate the atmospheric parameters (radiances, transmittances). A comparison between the diffuse transmittance from sky measurements and that simulated allow to check the validity of the proposed method. The context of the study is calibration and validation in remote sensing using only the radiative properties of the atmosphere. A sensitivity study of the method to various parameters and an error budget will be reported.

Abstract

The present work analyzes the potential of NASA EO-1 Hyperion imaging spectrometer to characterize urban structure from summer-based cloud free data over downtown Montreal (Quebec, Canada). This spaceborne hyperspectral sensor provides Earth imagery at 30 m spatial resolution, 7.5 km swath in 220 contiguous spectral bands between 400 and 2500 nm with 10 nm spectral resolution. The investigations were carried out from a slight off-nadir imagery over Montreal (Canada) in order to respond to wireless telecommunication needs. A compiled urban material spectral library is also considered. Reduction to ground radiance (apparent reflectance) was achieved from several calibration procedures. Thereafter, well-established mapping techniques were considered to characterize urban materials, especially roofs and walls of buildings. The preliminaries results highlight the potential of spaceborne hyperspectral for urban space characterization.

Abstract

[1] Atmospheric water vapor is a key parameter for the analysis of climatic systems (greenhouse gas effect), in particular over high latitudes where water vapor displays an important seasonal variability. The sparse spatial and temporal sampling of atmospheric water vapor observations across Canada needs to be improved. A series of instruments and methods including a 940-nm solar absorption band radiometer (R) and radiosonde (S) analysis from a numerical weather prediction model and a ground-based bi-frequency Global Positioning System (GPS) were used to evaluate the integrated atmospheric water vapor (IWV) at various sites in Canada and Alaska from a multiyear database. The IWV-R measurements were collected within the framework of the North American Sun Radiometry network (AERONET/AEROCAN). Intercomparisons between [IWV-GPS and IWV-S], [IWV-R and IWV-GPS], and [IWV-R and IWV-S] show root mean square (RMS) differences of 1.8, 1.9, and 2.2 kg m � 2 , respectively. GPS meteorology appears to be the easiest approach to calibrate the solar radiometer water vapor band owing to its flexibility, and it allows us to overcome the Sun radiometry limitation in high-latitude areas like the Arctic. The sensitivity of the GPS retrieval to various parameters like GPS satellite constellation and meteorological data are discussed. The classical linear relationship between the surface temperature and the integrated weighted mean temperature profile needed for IWV-GPS retrieval may be significantly different for Arctic air masses compared with midlatitude air masses in the case of tropospheric temperature profile inversion. An ever-expanding multiyear (1994–2001) North American summer water vapor climatology, derived from AERONET/Canadian Sun Radiometer Network, is presented and analyzed, showing a mean value of 19.8 ± 6.1 kg m � 2 and variations from 17 kg m � 2 in Alaska to 23 kg m � 2 in southeastern Canada. The results in Bonanza Creek, Alaska, show significant interannual variations with a peak in 1997, which may

Abstract

The Arctic is known as a key area for the detection of climate changes and atmospheric pollution on a global scale. In this paper we describe a new Canadian sunphotometer network called AEROCAN, whose primary mandate is to establish a climatology of atmospheric aerosols. This network is part of AERONET, the worldwide federated sunphotometer network managed by the NASA Goddard Space Flight Center. The potential of sunphotometer data from the AERONET/AEROCAN network for monitoring of Arctic aerosols is illustrated, using examples of the multiyear variation of aerosol optical properties and atmospheric precipitable water vapour content at some stations, and in particular at Bonanza Creek, Alaska since 1994. Despite its sparse spatial density, the network represents an important tool for monitoring the spatio-temporal variation of Arctic aerosols. It also represents an important source of independent aerosol data, which we feel should be further developed in northern areas to improve our understanding of how atmospheric aerosols influence global climate.
