    Aplasia of the optic nerve is an extraordinarily rare congenital anomaly that affects one or both optic nerves and is associated with the absence of the central retinal vessel and retinal ganglion cells. We report a case of unilateral optic nerve aplasia in a 4-month-old infant who was found to have left microphthalmos on routine postnatal checkup. Family history, antenatal history, and systemic evaluation were unremarkable. Magnetic resonance imaging showed absent left optic nerve with left microphthalmos. The optic chiasm was present and slightly deviated towards the right side. The remaining cerebral and ocular structures were normal.

    Pure red cell aplasia is an uncommon complication of diphenylhydantoin therapy. It has not been reported in Indian literature. Awareness of the entity helps in establishing the cause of anaemia in these patients and alerts the physicians to the need of comprehensive haematological monitoring in these patients. A case of 58-year-old male who developed pure red cell aplasia following three months of diphenylhydantoin therapy is reported here.

    1985-01-01

    On the basis of the studies of the embryogenesis of the vagina, the authors consider that malformations classically described as being partial aplasia should not be separated from the total absence of the vagina. The important feature is the association of a functioning or non functioning uterus with the absence of the vagina. They believe that it is incorrect to describe the pouch of menstrual retention associated with a functioning uterus as "haematocolpos" and that is not justified to describe the cup-shaped vestibular depression as "hemi-vagina". According to the authors, although vaginal aplasia with a functioning uterus forming a pouch of menstrual retention constitutes an absolute indication for surgery, surgery is not justified in cases of vaginal aplasia with a non functioning uterus. If Frank's method fails in these cases, the patient or the couple should be referred to a sexologist, as women with this anomaly retain a perfect femininity, although unable to conceive.

    Congenital skin aplasia, or aplasia cutis congenita (ACC) is a rare congenital disease. It is characterized by the absence of skin at birth, localized or widespread, of one or several areas. This condition commonly involve the scalp but can also involve more rarely the trunk or limbs. However it is most frequently an isolated disorder, it can be associated with other anomalies, such as the Adams-Oliver syndrome, the association with a fetus papyraceus or with an epidermolysis bullosa. Many hypothesis have been suggested: vascular, genetic, traumatic, pharmacological or an anomaly in the neural tube closure process, but the exact mechanism is still unknown. Morbidity and mortality of this malformation depends on the affected area and the size of the defect. The main risk is the infection, hemorrhage and thrombosis in the case of a scalp defect with an underlying bone defect, the exposure of the meninges and the superior sagittal sinus. The initial management of ACC will therefore involve several plastic surgery techniques, from more simple to more complex, using conservative wound care to flaps techniques. Other techniques can be performed later, in the management of ACC sequelae, such as skin expansion for scarring alopecia. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Full Text Available Pulmonary aplasia is a rare congenital anomaly in which there are absence of pulmonary vessels, bronchus and parenchyma. It is distinguished from pulmonary agenesis by the presence of rudimentary stump bronchus. Patients are usually diagnosed in childhood. Patients without additional anomaly and the patients with mild disease can be diagnosed in adulthood. The left lung was not observed at the chest X-ray of 19-year-old male patient with respiratory distress in exercise. Left lung aplasia was diagnosed by computed tomography and ventilation perfusion scintigraphy. The patients with lung aplasia have an increased risk of infections. Therefore the follow-up of the patients is important.

    Full Text Available Aplasia cutis congenita is a rare disorder, which presents with congenital absence of skin. Besides isolated presentation, it may manifest with other developmental malformation of cardiovascular, gastrointestinal, genitourinary and central nervous systems, and malformation syndromes such as chromosomal abnormalities, Adams-Oliver syndrome, Bart′s syndrome, and Johanson-Bilzzard syndrome. Here, we present two cases of aplasia cutis congenita, which represent two different types of the disease. The first case presented as non-syndromic aplasia cutis congenita of scalp, and the other case presented as a part of Bart′s syndrome.

  14. Unilateral aplasia of both cruciate ligaments

    Directory of Open Access Journals (Sweden)

    2010-02-01

    Full Text Available Abstract Aplasia of both cruciate ligaments is a rare congenital disorder. A 28-year-old male presented with pain and the feeling of instability of his right knee after trauma. The provided MRI and previous arthroscopy reports did not indicate any abnormalities except cruciate ligament tears. He was referred to us for reconstruction of both cruciate ligaments. The patient again underwent arthroscopy which revealed a hypoplasia of the medial trochlea and an extremely narrow intercondylar notch. The tibia revealed a missing anterior cruciate ligament (ACL footprint and a single bump with a complete coverage with articular cartilage. There was no room for an ACL graft. A posterior cruciate ligament could not be identified. The procedure was ended since a ligament reconstruction did not appear reasonable. A significant notch plasty if not a partial resection of the condyles would have been necessary to implant a ligament graft. It is most likely that this would not lead to good knee stability. If the surgeon would have retrieved the contralateral hamstrings at the beginning of the planned ligament reconstruction a significant damage would have occurred to the patient. Even in seemingly clear diagnostic findings the arthroscopic surgeon should take this rare abdnormality into consideration and be familiar with the respective radiological findings. We refer the abnormal finding of only one tibial spine to as the "dromedar-sign" as opposed to the two (medial and a lateral tibial spines in a normal knee. This may be used as a hint for aplasia of the cruciate ligaments.

    2008-01-01

    Five reports have examined unilateral submandibular gland aplasia. The purposes of this report are to demonstrate submandibular gland aplasia leading to contralateral gland hypertrophy in the setting of oral cavity cancer and to discuss the corresponding diagnostic and management challenges. This study is a case report of a 60-year-old male who presented with pain on the right side of the mobile tongue. This report uses literature review. A 60-year-old male presented with pain on the right side of the mobile tongue. Subsequent results of punch biopsy revealed squamous cell carcinoma in situ with foci of microinvasion of the tongue. Head and neck examination revealed no abnormalities. The patient underwent a wide-local excision of the tongue lesion. Postoperative computed tomographic (CT) scan showed an asymmetric mass on the ipsilateral side of the cancer in the region of the submandibular gland. The gland was noted to be abnormally large. A diagnosis of contralateral submandibular gland aplasia was made. The patient is cancer-free at 2 years postlocal excision. Salivary gland aplasia is an extremely rare disorder and is often associated with various congenital syndromes. Unilateral submandibular gland aplasia is even rarer with ours representing the sixth reported case. Aplasia is believed to stem from a regional disturbance in early fetal development. Common symptoms can include dysphagia, dry mouth, decreased taste, and tooth decay. In the presence of a history of oral cavity cancer, unilateral submandibular gland aplasia poses a challenge during postoperative cancer follow-up. Unilateral submandibular gland aplasia in the setting of oral cavity cancer poses a unique challenge for cancer follow-up. Hypertrophy of the submandibular gland on the other side can masquerade as nodal metastasis. Head and neck examination as well as CT scan can be inconclusive. Regular confirmatory tests such as fine needle aspiration biopsy and positron emission tomography/CT for

    To describe the underrecognized inner ear malformation characterized by complete aplasia of the labyrinthine semicircular canals associated with a relatively well-formed cochlea, to investigate its relationship with known syndromic forms of hearing loss, and to hypothesize regarding the potential embryopathogenesis of this anomaly. A retrospective case review consisting of cases of sensorineural hearing loss with radiographic evidence demonstrating agenesis of the semicircular canals associated with a cochlea that was either morphologically normal or sufficiently well developed to accommodate the full insertion of a cochlear implant electrode. Cases were identified by computerized tomography findings that identified the anomaly under study. Departments of otolaryngology and radiology in a tertiary referral center, with a large cochlear implant program serving over 800 patients, more than half of whom are children. Fifteen patients with the anomaly under study were identified. Each patient underwent a complete otologic examination, audiometric studies, and high resolution computerized tomography of the temporal bone in axial and coronal planes. The bony morphology of the cochlea, round and oval windows, vestibule, semicircular canals, and vestibular aqueduct, and the course of the facial nerve were examined. Auditory findings and otologic treatment are presented. Of the 15 identified patients, 4 were nonsyndromic, 9 had CHARGE association (Coloboma of the eye, congenital Heart defects, choanal Atresia, mental and/or growth Retardation, Genital hypoplasia, and Ear anomalies and/or deafness), 1 met criteria for Noonan's syndrome, and one had features of both these syndromes. Although the cochlea was present in all cases, the cochlear morphology was usually abnormal in the CHARGE association patients. Of the 20 ears in the CHARGE subjects, only 3 ears (15%) were seen to have completely normal development of the cochlea in both the basal and upper turns. The others

    Aplasia cutis congenita (ACC) is a rare congenital malformation that commonly involves the scalp, but can affect pericranium, bone and dura mater. Complications are rare, but can be fatal, so early treatment must be achieved. The treatment remains controversial with no consensus between the conservative and surgical approach. The aim of this study is to describe our experience in the management of ACC. Retrospective review of the medical records of all children up to 14 years diagnosed with ACC and treated between 2000 and 2013. There were a total of 22 cases of ACC with lesions ranging from 1cm (0.79 cm(2)) to 14cm (153.94 cm(2)). ACC of the scalp was found in 18 cases, with 3 in extremities and 1 in trunk. Conservative treatment was performed on 9 patients and 13 underwent surgical treatment (8 primary closures, 2 plasties, 2 skin grafts, and 1 skin flap). Two patients died due to complications of other diseases not related with the ACC. ACC is a rare disease that can be fatal. A complete initial assessment to establish early treatment is necessary to prevent this. Surgery should be considered as an initial therapeutic option in defects >4cm (>12.6 cm(2)) as it prevents the risk of fatal complications. Copyright © 2014 Asociación Española de Pediatría.

    Aplasia cutis congenita (ACC) is a rare malformation characterized by absent or scarred areas of skin at birth. Although most commonly found on the scalp, ACC can also involve other locations. Its etiology and pathogenesis remain unclear. To describe the epidemiologic, clinical, therapeutic, and evolutionary aspects of ACC through a hospital series. We conducted a retrospective study from 1995 to 2012 and reported all cases of ACC. We enrolled 22 cases (14 girls and eight boys) of ACC during 18 years. The mean age at diagnosis was 5.7 years. Sixteen ACC involved the scalp, five the trunk, and one the left buttock. ACC was oval-shaped in 20 cases, triangular in one case, and linear in one case. The mean size was 4 cm. ACC was associated with bone defects in two cases, various malformations in eight (37.1%), and with syndromic malformation in three (Adams-Olivier syndrome: two cases; Goltz syndrome: one case). Conservative treatment consisting of wound dressing with vaseline was indicated in six cases. Bone reconstruction was performed in two cases. Regular follow-up and no treatment was recommended in 14 cases. Our study emphasizes the frequent association of ACC with malformations (37.1%) and bone defects (9%). © 2015 The International Society of Dermatology.

    Full Text Available Aplasia of the mandibular condyle is extremely rare when not seen in association with or as a part of any syndrome. The incidence is estimated to be 1 in 5.600 births. Growth disturbances in the development of the mandibular condyle may occur in utero late in the first trimester and may result in disorders, such as aplasia or hypoplasia of the mandibular condyle. We report a case of aplasia of left mandibular condyle along with hypoplasia of right condylar head in a 20-year-old female patent. The patient reported to the clinic with the complaint of proclined upper front teeth, wanting to improve her esthetics. Clinical, conventional radiography and computer tomographic studies revealed the complete absence of condyle on the left and hypoplasia of the head of mandibular condyle on the right side. The etiology was unknown and on the basis of history, clinical study and radiological examination it was suggested to be of developmental origin.

    Cutis aplasia congenita (CAC), a congenital absence of skin and its appendages, may extend into underlying muscles and bones. The scalp is the commonest site and it may be associated with acrania. CAC presents either as a thin transparent membrane, a black eschar, an ulcer or a healed scar. The dilemma of either immediate surgical management or conservative treatment is much more pronounced in the presence of acrania. Two patients with scalp lesions measuring 12 x 8 cm and 14 x 12 cm respectively and one patient with 4 cm wide circumferential trunk cutis aplasia treated conservatively are presented. The conservative treatment is simple, easy to carry out, and effective even for large defects; therefore, it is recommended in cutis aplasia congenita till complete healing. Surgical interventions such as tissue expansion and resurfacing, contracture release, etc. are for the correction of subsequent deformity at a later date.

    Congenital absence of the parotid gland is a rare entity. Absence is most commonly unilateral, and is not associated with accessory glandular tissue. In the majority of reported cases, parotid gland aplasia is seen with craniofacial abnormalities or hypoplasia of other ectodermal structures, particularly the lacrimal glands. We present a 14-year-old male with bilateral parotid gland aplasia detected incidentally on MRI of the brain and then confirmed on neck CT. The studies also revealed accessory parotid tissue superficial to the left masseter muscle. There were no associated craniofacial abnormalities. The lacrimal glands and submandibular glands were normal. (orig.)

    Full Text Available Maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. The majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. Conventional radiographs could not differentiate between inflammatory mucosal thickening, neoplasm, and hypoplasia of the sinus. Computed tomography (CT and also cone beam computed tomography (CBCT are the proper modalities to detect these conditions. In the present study, CBCT findings of three cases with maxillary sinus hypoplasia and aplasia are reported.

    2008-01-01

    Aplasia cutis congenita (ACC) is a rare congenital defect in which localized or widespread areas of the skin are absent at birth. In the majority of cases, it is limited to the scalp especially on the vertex although other areas of the body may also be involved. Other congenital malformations can be associated with ACC. We present herein the case of a new born male with unilateral absence of skin on the extensor surface of the right lower leg. There was no associated malformation or skin disease such as blistering or nail abnormailty. According to the classification outlined by Frieden, the condition was diagnosed as type VII aplasia cutis congenita. The treatment of this large ulcer was conservative, wet dressing and prophylactic topical antibiotics. On follow up after 2 years showed that the patient was nearly cured of the ulcer and had only minimal scar formation. PMID:27303163

    This is a case report (and review of the literature) of a 12-year and 10-month-old girl with a rare congenital anomaly of uterus didelphys, unilateral cervix aplasia, and ipsilateral renal aplasia. She had severe dysmenorrhea from the first menses. In an effort to preserve fertility, a cervical fistula was made that closed over. A laparoscopic hemi-hysterectomy was done successfully and rapidly with laparoscopic morcellation. Because no ureter was present, it was not necessary to trace it. For this congenital anomaly, laparoscopic morcellation of the obstructed hemiuterus is the preferred treatment either as a primary procedure or as a secondary procedure following failure of a surgical cervical fistula for the young patient.

This study retrospectively reviewed the CT and MRI findings of five patients with SCC aplasia. The CT and MR findings were analyzed for SCC, direction of facial nerve canal, cochlea, vestibule, oval or round window, middle ear ossicles, and internal auditory canal (IAC). The subjects included three boys and two girls ranging in age from one to 120 months (mean age; 51 months). Four of the subjects had the CHARGE syndrome, and one had the Goldenhar syndrome. Moreover, four subjects had sensorineural hearing loss and one had combined hearing loss. The course of the facial nerve canal was abnormal in all five cases. Moreover, trapped cochlea and dysplastic modiolus were each observed in one case. Four subjects had atresia of the oval window; whereas ankylosis of the ossicles was present in three subjects. IAC stenosis was present in one patient with the CHARGE syndrome. The aberrant course of the facial nerve canal, atresia of the oval window, and abnormal ossicles were frequently associated in patients with SCC aplasia. In addition, the Goldenhar and CHARGE syndromes were also commonly associated syndromes.

    Pure red cell aplasia is an orphan disease, and as such lacks rationally established standard therapies. Most cases are idiopathic; a subset is antibody-mediated. There is overlap between idiopathic cases and those with T-cell large granular lymphocytic leukemia, hypogammaglobulinemia, and low-grade lymphomas. In each of the aforementioned, the pathogenetic mechanisms may involve autoreactive cytotoxic responses. We selected 62 uniformly diagnosed pure red cell aplasia patients and analyzed their pathophysiologic features and responsiveness to rationally applied first-line and salvage therapies in order to propose diagnostic and therapeutic algorithms that may be helpful in guiding the management of prospective patients, 52% of whom were idiopathic, while the others involved large granular lymphocytic leukemia, thymoma, and B-cell dyscrasia. T-cell-mediated responses ranged between a continuum from polyclonal to monoclonal (as seen in large granular lymphocytic leukemia). During a median observation period of 40 months, patients received a median of two different therapies to achieve remission. Frequently used therapy included calcineurin-inhibitors with a steroid taper yielding a first-line overall response rate of 76% (53/70). Oral cyclophosphamide showed activity, albeit lower than that produced by cyclosporine. Intravenous immunoglobulins were effective both in parvovirus patients and in hypogammaglobulinemia cases. In salvage settings, alemtuzumab is active, particularly in large granular lymphocytic leukemia-associated cases. Other potentially useful salvage options include rituximab, anti-thymocyte globulin and bortezomib. The workup of acquired pure red cell aplasia should include investigations of common pathological associations. Most effective therapies are directed against T-cell-mediated immunity, and therapeutic choices need to account for associated conditions that may help in choosing alternative salvage agents, such as intravenous immunoglobulin

    Conclusiones: La aplasia pulmonar es una entidad infrecuente. Debido a la variabilidad en la presentación clínica debe tenerse un alto índice de sospecha ante el hallazgo de la radiopacidad total del hemitórax. Los métodos diagnósticos que se utilizan son radiografía, tomografía y gammagrafía. Para confirmar el diagnóstico se requiere realizar broncoscopia. La escisión del muñón y la traslocación diafragmática se han descrito como opciones quirúrgicas de tratamiento.

    Thymoma, a rare epithelial neoplasm, is the most common anterior-superior mediastinal tumour. Thymoma can occur sporadically or in association with other conditions, such as myasthenia gravis, pure red cell aplasia (PRCA), and hypogammaglobulinemia. Only 5% of thymoma cases develop PRCA; however, 10-50% of patients presenting with PRCA have an associated spindle cell type thymoma. Thymoma complicated by PRCA is associated with a poor outcome. We report the case of a 38-year-old female who presented with chest pain, and was diagnosed with an anterior mediastinal mass. A thymectomy was performed, and histopathological examination revealed mixed thymoma; two months later, the patient developed PRCA. The present case reinforces the need for clinicians to be vigilant with thymoma patients, even following thymectomy.

    Full Text Available A case of pure red cell aplasia in a simultaneous kidney-pancreas transplant recipient on immunosuppressive therapy is reported here. The patient presented with anemia unresponsive to erythropoietin treatment. Bone marrow cytomorphology was highly suggestive of parvovirus pure red cell aplasia, which was confirmed with serology and polymerase chain reaction positive for parvovirus B19 DNA in peripheral blood. After the administration of intravenous immunoglobulin the anemia improved with a rising number of the reticulocytes.

    Philosophe et sinologue, François Jullien présente ici une conférence qu'il a prononcée auprès de chefs d'entreprise et dans le milieu du management. D'un côté, la conception européenne de l'efficacité est liée à la modélisation comme à la finalité et revendique l'action jusqu'à l'héroïsme ; de l'autre, la pensée chinoise de l'efficience, indirecte et discrète, s'appuie sur le potentiel de situation et induit des " transformations silencieuses ", sans éclat ni même événement. Par-delà cet écart, il s'agira d'interroger la nature de l'effectivité ; ou comment l'intervention humaine réussit à se brancher sur la propension des choses et s'y laisse intégrer. Ce propos se garde donc de séparer tant soit peu l'art d'opérer sur des situations et l'exercice de la philosophie ; en résultent des effets de lecture portant sur l'histoire du XXe siècle ainsi que la géopolitique - et géoéthique - à venir.

  6. A Patient with Unilateral Tibial Aplasia and Accessory Scrotum: A Pure Coincidence or Nonfortuitous Association?

    Directory of Open Access Journals (Sweden)

    Zoran Gucev

    2010-01-01

    Full Text Available Tibial aplasia is an uncommon lower limb malformation that can occur isolated or be part of a more complex malformation pattern. We describe a 9-year-old boy born after uneventful pregnancy and delivery. Family history was negative for maternal diabetes and other malformations. The patient presented with left tibial aplasia and homolateral prexial foot polydactyly. He also displayed enamel dysplasia and bifid scotum with cryptorchidism. Literature review failed to identify a significant syndromic association between lower limb defects of the tibial type and the genital anomalies reported here. The combination of tibial aplasia with midline genital malformations further supports the hypothesis that the tibial ray development mirrors the morphogenetic process of the radial structures. Accordingly, the malformation pattern observed in the present patient may be pathogenetically explained by an insult occurring during late blastogenesis.

    Flow cytometric reticulocyte quantification was assayed in ten patients undergoing bone marrow transplantation (BMT) with previous conditioning by chemotherapy and total body irradiation. A reticulocyte maturity index (RMI) was determined taking into account the RNA content. With the aim of testing the utility of RMI as an early predictor of functional recovery in marrow aplasia, other hematological indicators as neutrophils count were comparatively evaluated. Mean time elapsed between BMT and engraftment evidence by RMI was 17,6 days. In six patients the RMI was the earliest indicator of functional recovery. The applicability of this assay in the pursuit of radioinduced bone marrow aplasia is discussed. (authors). 4 refs., 4 figs., 2 tabs

    This case study reports on a patient who relapsed with thymoma (mixed type) nine years after tumor resection. After four courses of rescue chemotherapy (docetaxel and cisplatinum), the patient was further diagnosed with pure red cell aplasia. It was noticed that cyclosporin A (CsA), which was administered to treat aplasia, could reverse chemoresistance. Its mechanism is not completely clear, but the hypothesis of CsA inhibiting P-glycoprotein mediated drug efflux is the most acceptable.

    Full Text Available Background: Tibial aplasia is of heterogeneous aetiology, the majority of reports are sporadic. We describe the reconstruction procedures in two subjects - a daughter and father manifested autosomal dominant (AD inheritance of the bilateral tibial aplasia and split hand-foot syndrome. Materials and Methods: Reconstruction of these patients required multiple surgical procedures and orthoprosthesis was mandatory. The main goal of treatment was to achieve walking. Stabilization of the ankle joint by fibular-talar-chondrodesis on both sides, followed by bilateral Brown-procedure at the knee joint level has been applied accordingly. Results: The outcome was with improved function of the deformed limbs and walking was achieved with simultaneous designation of orthotic fitting. Conclusion: This is the first study encompassing the diagnosis and management of a father and daughter with bilateral tibial aplasia associated with variable split hand/foot deformity without foot ablation. Our patients showed the typical AD pattern of inheritance of split-hand/foot and tibial aplasia.

  6. Bullous aplasia cutis congenita: Case report and review of the literature

    Directory of Open Access Journals (Sweden)

    Maria Teresa Garcia-Romero

    2011-01-01

    Full Text Available Aplasia cutis congenita is a rare condition characterized by the absence of skin and sometimes other underlying structures such as bone or dura. It can be a part of various syndromes and can be associated with multiple genetic diseases, malformation patterns, or a combination of all. It is even considered as a form frustre of a neural tube defect in several literatures. Bullous aplasia cutis congenita is a clinical subtype of the condition, with extremely few cases reported in the literature. It presents as a cystic or bullous lesion at birth, which eventually transforms into an atrophic, flat scar covered by a thin epithelium. Some cases present with a dark collar hair sign around the lesion, which can be even more indicative of an underlying neural tube defect. Management remains controversial and depends on the characteristics of the lesion, but conservative treatment is usually chosen.

    2009-04-01

    Full Text Available Introduction: There are various reports of the prevalence of frontal sinus aplasia in different geographical areas and ethnic origins. The size and shape of frontal sinus is different among various populations. This study used CT scan images to investigate the frequency of absence of frontal sinuses in adults of northeastern Iran. Materials and Methods: The present study was performed retrospectively on the axial and coronal CT scans of the paranasal sinuses from a series of 588 patients who had referred to CT scan ward of Mashhad Imam Reza hospital without any other sinus pathology. Results: The mean age of patients was 44.39± 19.44 years. Unilateral and bilateral aplasia of frontal sinuses was seen in 36 and 51 patients, respectively. The dominant sinus was in the left side in 68.24% of cases. Conclusion: The lower incidence of frontal sinus aplasia in this particular ethnic and geographical area relative to other populations emphasizes the effect of environmental and genetic factors on the development of frontal sinuses.

    In veterinary medicine congenital abnormalities of the diaphragm and pericardium are rare, idiopathic malformations, being reported mainly in dogs. This report documents an unusual case of developmental defects in a foal consisting of diaphragmatic hernia concurrent with pericardial aplasia. Following a normal delivery, a full term, female Friesian stillborn foal with the placenta was presented for necropsy. External morphological examination indicated a normally developed foal. At necropsy, a large oval defect (approximately 20 × 15 cm in size) was observed in the left-dorsal side of the diaphragm (left lumbocostal triangle). This defect allowed the intestinal loops, spleen and partially the liver to translocate into the thorax. The loops of the left ascending colon, including the pelvic flexure and partially the small intestine covered the cranial and dorsal posterior parts of the heart due to the complete absence of the left pericardium. The remaining pericardium presented as a white, semi-transparent strip, partially covering the right side of the heart. The left lung and the main bronchus were severely hypoplastic to approximately one-fifth the size of their right homologue. The intermediate part of the liver, containing mainly the enlarged quadrate lobe was translocated in the thorax, severely enlarged and showed marked fibrosis. Histologically in the herniated lobes we diagnosed hepatic chronic passive congestion, telangiectasia and medial hypertrophy of blood vessels. Concomitant malformation involving diaphragmatic hernia and pericardial aplasia in horses have not been previously reported. Moreover, this is the first case describing pericardial aplasia in horse.

    2016-01-01

    The aim of the study was to assess the significance of environmental risk factors for teeth aplasia and hypoplasia in cleft lip and palate children. Two hundred and forty-seven cleft lip and palate (CLP) children were enrolled in the study including 105 (42.5%) with bilateral CLP and 57.5% with unilateral CLP. The mean age was 11.2±4.9 years. Teeth condition was assessed clinically and radiologically. The impact of risk factors for teeth anomalies was analyzed by retrospective data obtained from computer database (absence of preoperative orthopedic treatment, palatal defects after primary palatoplasty and type of primary procedures). Surgical trauma by early periosteoplasty (at the age of 3-4 months), excessive scarring and tissue traction due to absence of early orthopedic treatment and palatal defect were associated with significantly higher incidence of incisors hypoplasia (both developmental enamel defects and microdentia) and aplasia of central incisors not seen in the other study subgroups. Incisors aplasia and hypoplasia in CLP patients do not always have disembryogenic origin but may depend on external environmental factors, including surgical trauma.

    The objective of this study was to assess short-term benefits and risks of utero-vaginal anastomosis done for cases of cryptomenorrhea due to cervical atresia with vaginal aplasia. Prospective study. Surgical procedures were done between December 2013 and September 2015 at the department of Obstetrics and Gynecology, Cairo University Hospital. Five patients who had cryptomenorrhea due to cervical atresia associated with vaginal aplasia were included. Utero-vaginal anastomoses were performed in 2 stages; a stage of McIndoe vaginoplasty and a stage of excision of the atretic cervical tissue and anastomosing the uterus to the neovagina. Follow-up was done by gynecological and ultrasound examination in a duration ranged from 12 to 36 months. Occurrence of regular menstrual flow and relief of the severe cyclic pain. All patients had relief of the severe cyclic pain. Four patients had regular menstrual flow. One patient developed occlusion of the track after 1 year and needed dilatation once. Three patients developed low vaginal stenosis without occlusion of the track. One patient had rectal injury repaired without causing postoperative morbidity. Uterovaginal anastomosis is a promising conservative management option for cervical atresia with vaginal aplasia, which has benefits but is not free of risks. Long-term follow-up is still needed to judge its feasibility. We recommend performing McIndoe vaginoplasty as a starting stage before the anastomosis preferably in a separate setting.

    Comentários: A aplasia cutis congénita é uma lesão que pode ser causadora de grande ansiedade parental, pelo que é importante ao Pediatra o seu reconhecimento e devido esclarecimento. Apesar de se tratar, na maioria das vezes, de um defeito benigno, é importante o conhecimento da sua relação com outras anomalias e síndromes de forma a otimizar a sua orientação precoce e adequada. Da mesma forma, é importante o aconselhamento genético, nos casos que assim o justifiquem.

    Iron deposition can occur in the kidneys as a result of hemolysis or extensive iron overload from transfusions. With T2* MRI, renal iron deposition can be visualized. In this report, renal corticomedullary junction iron deposition is noted using T2* MRI in a boy with red cell aplasia. The renal corticomedullary junction iron deposition is an indication of the severity of his iron overload. This is an unusual finding and brings clinical attention to the boy's renal function for further evaluation. (orig.)

    Full Text Available Both pure red cell aplasia (PRCA and hypogammaglobulinemia are rarer conditions than myasthenia gravis (MG in thymoma patients. Several articles have discussed the relation between PRCA and thymoma or hypogammaglobulinemia and thymoma, and their proper treatments. Instances of both PRCA and hypogammaglobulinemia in a thymoma patient are few and reported sporadically in the literature. We discuss a 46-year-old woman with thymoma and simultaneous PRCA and hypogammaglobulinemia who achieved complete remission from PRCA after perioperative steroid administration and extended thymectomy, and review the literature.

  19. Bilateral posterior semicircular canal aplasia and atypical paroxysmal positional vertigo: a case report

    2008-01-01

    Summary Isolated congenital malformations of semicircular canals are rare abnormalities. Most inner ear abnormalities occur in syndromes and are associated with hearing loss. Unilateral or bilateral single aplasia of one semicircular canal does not usually result in vertigo, but these become clinically important if there are clinical complaints of vertigo. Computed tomography imaging and high resolution magnetic resonance imaging may reveal inner ear abnormalities. The case is presented here of a 46-year-old male with a 10-year history of recurrent positional vertigo with strong onset when changing position to the left side. Magnetic resonance imaging of the inner ear showed a bilateral posterior semicircular canal aplasia as well as an enlarged vestibule on both sides. Dix-Hallpike positional manoeuvre revealed a positional nystagmus in the left head-hanging position of short duration and latency of a few seconds. When rising, vertigo occurred, but no nystagmus was visible. The fast phase of the nystagmus was mainly vertical down-beating with a slight torsional component to the uppermost ear. Although benign paroxysmal vertigo of the anterior canal was suspected, physical therapy was not effective using a modified liberatory manoeuvre. Brandt-Daroff therapy was effective permanently.

    Background: Aplasia cutis congenita (ACC) is a part of a heterogeneous group of conditions characterized by the congenital absence of epidermis, dermis, and in some cases, subcutaneous tissues or bone usually involving the scalp vertex. There is an estimated incidence of 3 in 10,000 births resulting in a total number of 500 reported cases to date. The lesions may occur on every body surface although localized scalp lesions form the most frequent pattern (70%). Complete aplasia involving bone defects occurs in approximately 20% of cases. ACC can occur as an isolated defect or can be associated with a number of other congenital anomalies such as limb anomalies or embryologic malformations. In patients with large scalp and skull defects, there is increased risk of infection and bleeding along with increased mortality and therefore prompt and effective management is advised. Case Description: We describe two cases of ACC, involving a 4 × 3 cm defect managed conservatively and a larger 10 × 5 cm defect managed surgically with the use of a temporo-occipital scalp flap. Both cases had an excellent outcome. Conclusions: Multiple treatment regimens exist for ACC, but there is no consensus on treatment strategies. Conservative treatment has been described and advocated, but many authors have emphasized the disadvantages of this treatment modality. Decision between conservative and surgical management must be individualized according to lesion size and location. PMID:29204308

    This study aimed to gather statistically validated information on the changes in orthodontic variables in patients with bilateral upper lateral incisor aplasia treated with isolated orthodontic space closure. Data were collected from 25 (15 females, 10 males) consecutively treated, unselected adolescents [mean age at the end of treatment 16.4 years, standard deviation (SD) 1.3] after orthodontic space closure using push-and-pull mechanics (PPM). The changes in the relevant parameters were determined by comparing baseline and final lateral headfilms and casts. Following verification of normal distribution by means of a Kolmogorov-Smirnov test, a two-tailed t-test for related data was performed. SNA, ANB, OcP-NL, OcP-ML, upper space balance, overbite, overjet, bilateral molar relationship, and L1-NB changed significantly (P orthodontic space closure for bilateral upper lateral incisor aplasia using PPM can be regarded as a valid alternative to prosthetic solutions. Long-term use of Class III elastics does not lead to significant changes in relevant orthodontic parameters.

    A 30-year-old postpartum woman was admitted to our hospital because of progressive anemia, malaise, night sweating, headache and low grade fever which began 9 days after delivery (day 0). She had normocytic hypochromic anemia accompanied with marked decrease in reticulocytes. In addition, a temporary decrease in platelets and white blood cells especially neutrophils were observed. Bone marrow smears showed an apparent decrease in erythroid cells and the presence of giant proerythroblasts (1.2%) as well as hemophagocytes (1.2%). IgM and IgG antibody against human parvovirus B19 (HPV) was detected on day 22 of the disease although negative results were obtained on day 3. The presence of the virus in the blood on admission was confirmed by dot-blot analysis. Thus, this case was diagnosed as acute pure red cell aplasia and hemophagocytic syndrome caused by HPV infection. This patient had been given iron for iron deficiency anemia before delivery and the iron deficiency was still present after the episode of the present disease although the iron metabolism data was perturbed during the disease. These findings suggest that HPV could cause acute pure red cell aplasia not only in patients with hemolytic anemia but also in patients with iron deficiency anemia or after acute bleeding. Furthermore it is suggested that pancytopenia often observed on HPV infection could be at least partly caused by hemophagocytic syndrome.

    Nevus sebaceus syndrome (SNS) is a constellation of nevus sebaceus with extracutaneous findings, including the ophthalmologic nervous, and musculoskeletal systems. Didymosis aplasticosebacea is a recently described entity consisting of aplasia cutis congenita and nevus sebaceus, implying twin spotting (didymosis). We describe a neonate with a nevus sebaceus on the scalp and a limbal dermoid on her left eye. Contiguous with the nevus sebaceus was a giant congenital melanocytic nevus and numerous areas of membranous aplasia cutis congenita. We propose the acronym SCALP (nevus sebaceus, central nervous system malformations, aplasia cutis congenita, limbal dermoid, pigmented nevus) to summarize the unique features of this case and review the two similar cases in the literature.

    Localised agenesis of the scalp is the most frequent patern in aplasia cutis congenita (ACC), a congenital absence of the skin and occasionally of deeper layers. Several clinical groups are characterised by the location and pattern of skin defects, associated malformations and the mode of inheritance. Death occurs in 20 % of cases, secondary to the associated anomalies, to infections or to haemorrhage from ulceration of the sagittal sinus when there is also a defect of the underlying skull. In this latter case, we close the defect by two rotational scalp flaps (Orticochea technique) at birth. A three-dimensional CT study is useful for showing the extent of the skull defect and the deformity of the craniofacial complex and the changes in the bone after treatment. (orig.)

    Pure red cell aplasia (PRCA) and autoimmune hemolytic anemia (AIHA) have rarely been reported as an extrahepatic manifestation of acute hepatitis A (AHA). We report herein a case of AHA complicated by both PRCA and AIHA. A 49-year-old female with a diagnosis of AHA presented with severe anemia (hemoglobin level, 6.9 g/dL) during her clinical course. A diagnostic workup revealed AIHA and PRCA as the cause of the anemia. The patient was treated with an initial transfusion and corticosteroid therapy. Her anemia and liver function test were completely recovered by 9 months after the initial presentation. We review the clinical features and therapeutic strategies for this rare case of extrahepatic manifestation of AHA.

    Popliteal pterygium syndrome (PPS) and Van der Woude syndrome (VWS) are caused by mutations in the gene interferon regulatory factor 6 (IRF6). Skeletal, genital malformations and involvement of the skin occur in PPS and orofacial clefting and lip pits occur in both. We report on a patient with unilateral cleft lip and palate, ankyloblepharon, paramedian lip pits, unilateral renal aplasia, and a coronal hypospadias. By sequencing IRF6, we detected a novel missense mutation (Arg339Ile). The other family members were unaffected and had no IRF6 mutations, including the patient's brother who was also born with hypospadias. The patient and his brother were both conceived by in vitro fertilization (IVF). It is discussed whether the renal malformation in the patient is related to the IVF procedure or to the IRF6 mutation. 2008 Wiley-Liss, Inc.

    A thymoma with pure red cell aplasia (PRCA) is relatively rare. A 71-year-old woman complainted of dizziness and her blood cell count showed a severe anemia. She was diagnosed as PRCA by bone marrow aspiration biopsy, which showed marked decrease in number of erythroblasts. In addition, the chest computed tomography revealed a solid tumor in the anterior mediastinum. She underwent extended thymothymectomy through median sternotomy. The resected specimen was 10.5×9.7 cm in diameter. The pathological diagnosis was type AB thymoma of the World Health Organization classification, and Masaoka stage I. Ciclosporin was started to treat PRCA 3 months after the surgery, and she has been well for about 1 year after surgery without recurrence of thymoma or relapse of anemia.

    Objective: To discuss how to diagnose and treat thymoma associated with pure red cell aplasia (PRCA). Methods: Three patients of thymoma associated with PRCA were treated with thymothymectomy, and the local radiotherapy was conducted after operation for avoiding the thymoma reproduction. Determining of their peripheral blood hemoglobin was used to evaluate the postoperation result in PRCA. If PRCA can not be relieved, oral prednisone and cyclosporin A were given. Results: One patient with PRCA was cured, the second patient remained in remission by treatment with prednisone and CsA, and the third patient was in progress. Conclusion: The treatment by means of 'thymothymectomy-local radiotherapy-use of prednisone and CsA', is effective for thymoma associated with PRCA

    The isolated aplasia of the serratus anterior muscle with winging of scapula is very rare, and only a few cases are reported. Here, we present a case of a 30-year-old Korean male who initially presented with a left flank pain. His physical exam did not show any significant finding in his right shoulder. However, his chest radiograph showed absence of right serratus anterior muscle and slightly elevated and medially rotated right scapula. Subsequent CT scan showed the right serratus anterior muscle aplasia and medial winging of the right scapula. This case is unique in two aspects. First, the combination of abnormalities is different from the typical congenital abnormalities involving shoulder girdle, such as Sprengel deformity or Poland syndrome. Secondly, this was incidentally diagnosed with chest radiograph, without clinical impression. Careful reading of chest radiograph can help the radiologists to detect such clinically silent abnormalities.

    Agenesis of the paranasal sinuses is an uncommon clinical condition that appears mainly in the frontal (12%) and maxillary (5-6%) sinuses; in some populations, it appears at a higher proportion. This study investigated the prevalence of agenesis of the frontal sinuses using dental volumetric tomography (DVT) in Turkish individuals. The frontal sinuses of 410 patients were examined by DVT scans in the coronal planes for evidence of the absence of the frontal sinuses. A bilateral and unilateral absence of the frontal sinuses was seen in 0.73% and 1.22% of cases, respectively. In one case, both agenesis and aplasia of the frontal sinus was seen (0.24%). The low percentage of frontal sinus agenesis must be considered during pre-surgical planning related to the sinuses. DVT may be used as a diagnostic tool for the examination of frontal sinus aplasia.

    The lessons learnt from the treatment of previous radiation accidents using either bone marrow transplantation or growth factor therapy suggest that it is of importance to investigate new therapeutic regiments. Ex vivo expansion of haematopoietic stem cells, precursors and differentiated cells is a new approach of growth factor therapy which may be of interest for the treatment of patients with irradiation-induced bone marrow aplasia. Ex vivo expanded maturing cells could be used to limit the early risks bound to aplasia (infections related to granulocytopaenia, bleedings associated with thrombocytopaenia), whereas expanded immature cells could hasten haematopoietic recovery. Indeed, it is possible to culture from the blood or bone marrow the cells able to proliferate and differentiate. A sufficient quantity of cells to cover the transfusion needs of a radiation victim through an aplasia episode can be produced, in presence of a specific growth factor combination. Qualitative studies shows that the expanded cells exhibit a close to normal functionality. Long-term culture techniques demonstrate the expansion of immature cells. We have set up a high dose total body irradiation non-human primate model in order to study the therapeutic potential of ex vivo expansion of autologous progenitors and differentiating cells. All the steps of the process (sampling, positive selection of the immature cells, ex vivo expansion, irradiation of the animals, reinjection of the cultured cells and study of the outcome) are established. In order to allow the long term follow up of the ex vivo expanded haematopoietic cells (homing to the bone marrow or localization to specific organs for example), a retroviral gene transfer technique for transduction of green fluorescence protein (GFP) gene toward the selected immature blood or bone marrow cells is under development in this model.

    AIM: The purpose of this study was to evaluate the findings of three-dimensional (3D) volume rendering (VR) imaging in common crus aplasia (CCA) of the inner ear. MATERIALS AND METHODS: Using 3D VR imaging of temporal bone constructive interference in steady state (CISS) magnetic resonance (MR) images, we retrospectively reviewed seven inner ears of six children who were candidates for cochlear implants and who had been diagnosed with CCA. As controls, we used the same method to examine 402 inner ears of 201 patients who had no clinical symptoms or signs of sensorineural hearing loss. Temporal bone MR imaging (MRI) was performed with a 1.5 T MR machine using a CISS sequence, and VR of the inner ear was performed on a work station. Morphological image analysis was performed on rotation views of 3D VR images. RESULTS: In all seven cases, CCA was diagnosed by the absence of the common crus. The remaining superior semicircular canal (SCC) was normal in five and hypoplastic in two inner ears, while the posterior SCC was normal in all seven. One patient showed bilateral symmetrical CCA. Complicated combined anomalies were seen in the cochlea, vestibule and lateral SCC. CONCLUSION: 3D VR imaging findings with MR CISS sequence can directly diagnose CCA. This technique may be useful in delineating detailed anomalies of SCCs.

    Nivolumab is an antibody against programmed cell death 1 and functions as an immune checkpoint inhibitor for various malignancies, including unresectable melanomas. Nivolumab causes several immune-related adverse events, which typically include skin rash, pneumonitis, thyroid dysfunction, hepatitis, and colitis; in rare cases, anemia may be present. There are several reports of autoimmune hemolytic anemia that has developed in response to nivolumab; however, there are few reports of pure red cell aplasia (PRCA). We describe a patient who developed PRCA during nivolumab administration. A 70-year-old Japanese woman received nivolumab for cardiac metastasis from malignant melanoma from an unknown site. Twenty-one months after nivolumab administration (31 courses), treatment was discontinued because she developed severe anemia. Blood test results indicated normocytic, normochromic anemia, and reticulocytopenia, but all other components were normal. Bone marrow aspiration showed increased megakaryocytes and decreased erythroblasts; these findings were consistent with PRCA. Anemia improved without recurrence after treatment with corticosteroids and blood transfusions. The steroid dosage was reduced gradually, and to date, the patient has not experienced recurrence of anemia. The tumor decreased in size and the patient has shown a continued response to treatment with decrease in disease for 3 years. Although it is unclear how nivolumab causes PRCA, hematological toxicities have been reported in patients treated with immunotherapy drugs. PRCA might be an unrecognized immune-mediated adverse event that did not manifest during the clinical trial phase.

    Simultaneous onset of autoimmune hemolytic anemia (AIHA) and pure red cell aplasia (PRCA) is rare and any possible association between these two disorders remains obscure. A 46-year-old previously healthy woman was diagnosed as having AIHA based on severe anemia, positive direct and indirect Coomb's tests, decreased serum haptoglobin, elevated serum LDH, and indirect bilirubin-dominant hyperbilirubinemia. Oral steroid administration (1 mg/kg) and subsequent half-pulse steroid therapy ameliorated the AIHA, but the anemia was unexpectedly prolonged with the low peripheral blood reticulocyte count further decreasing to 0.11%. Bone marrow aspiration revealed a marked decrease in erythroblasts with an M/E ratio of 69.5. Anti-parvovirus B19 IgM antibody and serum B19 viral DNA (10 9 copy/ml) were detected but no other distinct abnormalities which might have caused acquired PRCA were detected. Therefore, she was considered likely to have idiopathic AIHA and acquired PRCA simultaneously. AIHA-mediated erythroblastosis probably raised the parvovirus B19 DNA level to an extraordinary degree and thereby led to severe aplastic crisis, subsequently causing prolonged anemia. Parvovirus B19 infection should be considered in AIHA patients showing unexpectedly low reticulocyte counts.

    We report a female patient with endocrine abnormalities, hypogonadotropic hypogonadism and amazia (breasts aplasia/hypoplasia but normal nipples and areolas) in a rare syndrome: Van Maldergem syndrome (VMS). Our patient was first evaluated at age 4 for intellectual disability, craniofacial features, and auditory malformations. At age 15, she presented with no breast development and other findings consistent with hypogonadotropic hypogonadism. At age 37, she underwent whole exome sequencing (WES) to identify pathogenic variants. WES revealed compound heterozygous variants in DCHS1 (rs145099391:G > A, p.P197L & rs753548138:G > A, p .T2334 M) [RefSeq NM_003737.3], diagnostic of Van Maldergem syndrome (VMS-1). VMS is a rare autosomal disorder reported in only 13 patients, characterized by intellectual disability, typical craniofacial features, auditory malformations, hearing loss, skeletal and limb malformations, brain abnormalities with periventricular neuronal heterotopia and other variable anomalies. Our patient had similar phenotypic abnormalities. She also had hypogonadotropic hypogonadism and amazia. Based on the clinical findings reported, two previously published patients with VMS may also have been affected by hypogonadotropic hypogonadism, but endocrine abnormalities were not evaluated or mentioned. This case highlights an individual with VMS, characterized by compound heterozygous variants in DCHS1 . Our observations may provide additional information on the phenotypic spectrum of VMS, including hypogonadotropic hypogonadism and amazia. However, the molecular genetic basis for endocrine anomalies observed in some VMS patients, including ours, remains unexplained.

    The present study aimed to determine whether routine orthodontic space closure can be successfully achieved in patients with unilateral aplasia of the lower second premolars without extracting contralateral or opposing teeth. The dental records and lateral cephalograms of 17 consecutively treated subjects (11 females, 6 males) aged between 14.8 and 19.3 years at the end of active treatment (mean 16.1 years) were analysed. The spaces were closed by 'push-and-pull' mechanics (PPM). Pre- and post-treatment data were compared using a Student's t-test. At the end of active treatment, all parameters (ANB, SNA, SNB, ML/NL, U1-NA, L1-NB, overbite and overjet, upper and lower midline, upper and lower space balance) presented mean values close to accepted norms with satisfactory standard deviations (SDs). Five indicators of success changed significantly: (1) Space closure in the aplastic region was achieved. (2) On the aplastic side, a mean mesial molar relationship of 1.12 (SD 0.18) cusp width (cw) was achieved. The mean alteration from pre- to post-treatment was 1.53 cw (SD 0.29, P space and balanced space ratios.

    Aplasia cutis congenita is a rare malformation characterized by localized congenital absence of the skin. It rarely occurs on the trunk and limbs, and can occur in isolation or as part of a heterogeneous group of syndromes. We report a case of a 4-day-old boy with a 5.6-cm- diameter tumor, with a central crust, non-indurate and no inflammatory rim; localized on the scalp and a small, atrophic hairless scar appeared 6 months later (approximately 5cm in length) at the site of the previous tumor.

    2002-12-01

    After a description of the context of medullary aplasia (haematological radiobiology, radiation acute syndrome, therapeutic care), and an overview of knowledge about the interleukin-1 and medullary stroma cells, this research thesis aims at investigating therapeutic alternatives for radio-accidental aplasia. More precisely, it aims at defining means to get cytokines which are efficient for haematopoiesis. Interleukin-1 is chosen for its properties and tests are performed on a macaque with two approaches for gene transfer: an ex vivo transfer by retroviral vector enabling an integration in the target cell genome, and an in situ transfer by adeno-viral vector directly applied in the animal osseous medulla

    2014-01-01

    Objectives Aplasia cutis congenita is a rare congenital condition, and it is difficult to find scientific support for optimal treatment strategies. In addition, these may vary due to defect size, tissue layers involved, contemporary malformations, and the physiologic status of the affected child. Clinical Presentation This case report describes complete skin coverage in 20 weeks and uneventful healing of a large 11 × 9-cm defect of the vertex, involving both skin and skull bone, using conservative treatment. To prevent infection and promote healing, the defect was kept moist and covered at all times, and it was treated with surgical debridement when necessary. For infection control, ionized silver-coated dressings were used in addition to prophylactic antibiotics over the first 3.5 weeks. Follow-up was 2 years. Conclusion Surgical treatment is usually preferred for larger aplasia cutis congenita defects, but it is accompanied with potential risks and will exacerbate secondary reconstruction of alopecia or skull bone defects. This case shows that even very complex defects may be treated conservatively. PMID:25485218

    An eighteen-year-old female with Graves thyrotoxicosis presented with methimazole-induced agranulocytosis and total myeloid aplasia. The bone marrow at presentation showed complete absence of myeloid precursors and striking plasmacytosis. 16 days later, myeloid precursors were still absent morphologically; however bone marrow flow cytometry and cell culture detected an improvement in myelogenesis, which was soon followed by clinical recovery of agranulocytosis. Neutrophil recovery was delayed until day 22 after cessation of methimazole despite G-CSF use, consistent with a direct toxic effect on committed myeloid cells. Our findings suggest that cell culture and flow cytometric evaluation of bone marrow myeloid progenitors can be used as a guide to anticipate neutrophil recovery.

    A 64-year-old woman developed pure red cell aplasia (PRCA) 4 years after thymectomy for thymoma. During anti-thymocyte globulin treatment, the patient developed cytomegalovirus pneumonia and was thus unable to continue immunosuppressive therapy and became transfusion dependent. Deferasirox was started for treatment with iron overload when serum ferritin increased to >1000 ng/mL. Seven months after initiation of deferasirox treatment, serum ferritin level decreased the normal range and the patient has remained transfusion independent thereafter. Deferasirox was discontinued when serum ferritin level decreased below 500 ng/mL, and she has maintained in complete remission over the last 15 months. Hypotheses have been raised regarding the improvement of hematopoiesis by deferasirox treatment, but the mechanism whereby this might be achieved remains unclear. Deferasirox treatment may be clinically beneficial both by reducing iron overload and by improving hematopoiesis in patients with PRCA.

It was first described in 1987 by Stock; the mechanism involved is an immunologically mediated condition secondary to an unknown viral infection. The disease is associated with a dismal prognosis. Spontaneous recovery from acquired AA is very rare however some patients (50-70% recover after immunosuppressive therapy, such as Cyclosporin A (CsA and Antithymocyte globulin (ATG, even after liver transplantation. Another treatment option is bone marrow transplantation.

    Full Text Available À la tête du Pérou de 1990 à 2000, Alberto Fujimori a su rester populaire en combinant les recettes traditionnelles et nouvelles du populisme. Le discrédit des partis politiques et des syndicats a constitué un contexte favorable à l’arrivée et au maintien au pouvoir de ce non-professionnel de la politique, auquel des valeurs d’honnêteté et de compétence ont été spontanément prêtées. Le chef d’Etat péruvien a construit en outre, tout au long de ses mandats successifs, une stratégie politique destinée à asseoir sa légitimité. Cette stratégie s’est fondée sur des actions telles que : la mise en place d’une relation directe et quasi affective avec les couches les plus défavorisées de la population par le biais de pratiques clientélistes ; la déstructuration du tissu social dans l’objectif d’éviter toute opposition et de renforcer le pouvoir du chef de l’Etat ; l’instrumentalisation de certains groupes d’acteurs, notamment par l’intermédiaire des programmes sociaux ; enfin, le contrôle permanent, et sans cesse renforcé, de l’information, via la surveillance des médias et des opposants. Fondée sur une image d’efficacité, la gestion politique d’Alberto Fujimori est demeurée populaire jusqu’à la fin des années 1990, lorsque la révélation d’affaires de corruption a accéléré la chute de son régime.Presidente de Perú de 1990 a 2000, Alberto Fujimori supo conservar su popularidad mezclando viejas y nuevas recetas del populismo.

  2. CD19 CAR-targeted T cells induce long-term remission and B Cell Aplasia in an immunocompetent mouse model of B cell acute lymphoblastic leukemia.

    Directory of Open Access Journals (Sweden)

    Marco L Davila

    Full Text Available Although many adults with B cell acute lymphoblastic leukemia (B-ALL are induced into remission, most will relapse, underscoring the dire need for novel therapies for this disease. We developed murine CD19-specific chimeric antigen receptors (CARs and an immunocompetent mouse model of B-ALL that recapitulates the disease at genetic, cellular, and pathologic levels. Mouse T cells transduced with an all-murine CD3ζ/CD28-based CAR that is equivalent to the one being used in our clinical trials, eradicate B-ALL in mice and mediate long-term B cell aplasias. In this model, we find that increasing conditioning chemotherapy increases tumor eradication, B cell aplasia, and CAR-modified T cell persistence. Quantification of recipient B lineage cells allowed us to estimate an in vivo effector to endogenous target ratio for B cell aplasia maintenance. In mice exhibiting a dramatic B cell reduction we identified a small population of progenitor B cells in the bone marrow that may serve as a reservoir for long-term CAR-modified T cell stimulation. Lastly, we determine that infusion of CD8+ CAR-modified T cells alone is sufficient to maintain long-term B cell eradication. The mouse model we report here should prove valuable for investigating CAR-based and other therapies for adult B-ALL.

    A thymoma with pure red cell aplasia( PRCA) is relatively rare, and the treatment of the disease has not established yet. We describe a case of a thymoma associated with PRCA treated with a surgery and remission-induction therapy by ciclosporin. An 80-year-old man complained of dizziness and his blood cell count showed a severe anemia. He was diagnosed as PRCA by bone-marrow aspiration biopsy, which showed abatement of erythroblasts. In addition, the chest computed tomography revealed a solid tumor in the anterior mediastinum, strongly suggesting a thymoma. Oral administration of ciclosporin as remission-induction therapy for PRCA was started at 1st. The treatment contributed to partial remission for PRCA without blood transfusion. Consecutively thymectomy through median sternotomy was performed at 6 weeks after initiation of the treatment without any transfusions or complications. Histology of the solid tumor showed the thymoma of type B2 in World Health Organization (WHO) category. We continued to treat PRCA with ciclosporin after the surgery. The patient has been surviving for 2 years after surgery without any recurrence of thymoma or relapse of anemia. Combined therapy of surgery and remission-induction therapy with ciclosporin assumed to be a good strategy of the treatment for the patient with a thymoma associated with PRCA.

    Full Text Available BACKGROUND The incidence of Prelingual deafness with bilateral profound sensory neural hearing loss varies among different regions with overall prevalence rate of one case per 1000 live births. Overall, there are more than 40 million such children all over the World. Hearing losses may be genetic or non-genetic. Genetic hearing losses (50% may be syndromic (15% or nonsyndromic (35%. Genetic hearing loss may be Autosomal or X-linked, Dominant or Recessive, Syndromic or Non-Syndromic. Adequate radiological assessment and confirmation of select cases is utmost important before proceeding to cochlear implant surgery. This study aims at a statistical analysis of various radiological presentation in bilateral profound sensory neural hearing loss in prelingual deafness children selected for cochlear implant in our Institution for a period of one year from January 2016 to January 2017, with study and analysis of Michel’s Aplasia and its variations included in the study. MATERIALS AND METHODS The study is done as a retrospective study at Vellore Medical College at the ENT Department for a period of one year from Jan 2016- Jan 2017, based on the radiological presentation of 20 children included in the study group with other prior investigations. Interpretation was done based on the inner ear anomalies and individual variations are analysed. Study Design- Retrospective study. RESULTS Radiological analysis of 20 cases included in the study group of Prelingual deafness candidates with bilateral profound sensory neural hearing loss selected for cochlear implant showed that three cases had Michel’s Aplasia with individual radiological variations which were analysed, while other cases had radiologically normal middle and inner ear. CONCLUSION Inner ear anomalies of children with bilateral profound sensory neural hearing loss are variable. Although, incomplete partition type and cochlear Hypoplasia type are common according to International studies, Michel

    We report VEMP results in a patient with aplasia of bilateral semicircular canals and a small vestibular cavity. The patient was a 27-year-old male. The computed tomograph showed absolutely no formation of his semicircular canals, together with hypoplasia of his vestibular cavity and cochlea in both ears. His oVEMP was recorded near the extraocular muscles on the left side when elicited by BCV in the Fz. The clinical profile of this patient suggested that oVEMP elicited by BCV recorded near the extraocular muscles originated from otolithic end organs, and not from semicircular canal afferents.

    Aplasia Cutis Congenita (ACC) is a rare condition characterized by the absence of a portion of skin at birth. Skin defects are usually small (0.5 to 3 cm) and located on the scalp. Although there can be other physical or genetic abnormalities, ACC is most often a benign isolated condition. Rarely is an underlying bony defect present, and this association increases the rate of complications. We report a case of a newborn male with ACC of the entire crown and vertex scalp, non-ossified parietal skull and dysplastic corpus callosum. The patient's skull and skin defects were treated non-surgically, and he recovered well.

La distribution tend dans tous les cas vers un schema type qui se maintient ensuite identique a lui-meme en fonction de la charge corporelle. L'analyse biochimique de l'etat du cesium dans les milieux biologiques montre qu'il y est transporte sous une forme libre et ionisee. Abordant le probleme du mode de penetration de l'ion cesium dans le milieu intracellulaire et notamment par l'etude cinetique du systeme plasma-hematie in vivo et in vitro, les auteurs adoptent l'hypothese d'un transport actif du cesium par la membrane cellulaire. Ils en arrivent ainsi a un schema general de la distribution du cesium dans l'organisme, essentiellement caracterise par un equilibre dynamique de repartition entre deux compartiments: 99 pour cent du cesium est accumule dans le pool intracellulaire, 1 pour cent dans les liquides extracellulaires. Ce dernier compartiment est ouvert sur les emonctoires. Du fait du transport actif par les membranes cellulaires, la charge du pool intracellulaire est rapide, mais la decharge est lente. Ce phenomene est le facteur limitant de la decroissance de la charge corporelle. De ce schema les auteurs deduisent les raisons de l'echec relatif des diverses voies therapeutiques explorees a ce jour par eux-memes, et par d'autres auteurs. La stimulation des emonctoires naturels, dans le cas des diuretiques par exemple, ne saurait accroitre que l'epuration du compartiment extracellulaire. Or ce dernier ne contient que 1 pour cent de la charge corporelle et sa recharge est lente. En outre, les procedes visant a contrarier ou inhiber le transport actif du cesium par la membrane cellulaire restent, a ce jour, incompatibles avec la survie de la cellule. (auteurs)

    We followed the biological fate of a complex formed on one side with either a rare earth (cerium-144) or a transuranium element (plutonium-239), and on the other side with a chelating agent of the polyamino acid series (EDTA, BAETA, DTPA, TTHA). This method allowed to study: 1 - the in vivo stability of the various complexes and to compare them; 2 - the stability of the complexes as a function of the isotope - chelating agent weight relationships; 3 - the metabolism of the chelating agents resulting in stable complexes, i. e. DTPA and TTHA mainly. This simple method brought out the higher efficiency, of DTPA in chelating rare earths and plutonium and for therapeutic purposes.

  14. Amelioration de l'efficacite energetique du procede d'electrolyse de l'aluminium conception d'un nouveau bloc cathodique

    Blais, Mathieu

    Au Quebec, les alumineries sont de grandes consommatrices d'energie electrique, soit pres de 14 % de la puissance installee d'Hydro-Quebec. Dans ce contexte, des petits gains en efficacite energetique des cuves d'electrolyse pourraient avoir un impact important sur la reduction globale de la consommation d'electricite. Le projet de maitrise decrit dans cette etude repond a la problematique suivante : comment l'optimisation de la geometrie d'un bloc cathodique en vue d'uniformiser la densite de courant peut augmenter l'efficacite energetique et la duree de vie de la cuve d'aluminium? Le but premier du projet est de modifier la geometrie en vue d'ameliorer le comportement thermoelectrique des blocs cathodiques et d'accroitre par le fait meme l'efficacite energetique du procede de production d'aluminium. La mauvaise distribution de la densite de courant dans la cuve est responsable de certains problemes energetiques ayant des impacts negatifs sur l'economie et l'environnement. Cette non-uniformite de la distribution du courant induit une usure prematuree de la surface de la cathode et contribue a reduire la stabilite magnetohydrodynamique de la nappe de metal liquide. Afin de quantifier les impacts que peut avoir l'uniformisation de la densite de courant a travers le bloc cathodique, un modele d'un bloc cathodique d'une cuve de la technologie AP-30 a ete concu et analyse par elements finis. A partir de son comportement thermoelectrique et de donnees experimentales d'une cuve AP-30 tirees de la litterature, une correlation entre le profil de densite de courant a la surface du bloc et le taux d'erosion local au meme endroit a ete creee. Cette relation correspond au modele predictif de la duree de vie de tout bloc du meme materiau a partir de son profil de densite de courant. Ensuite, une programmation a ete faite incorporant dans une meme fonction cout les impacts economiques de la duree de vie, de la chute de voltage cathodique et de l'utilisation de nouveaux materiaux

    Full Text Available A laboratory study has been undertaken to elucidate the influence of structural parameters of polymer/electrolyte systems commonly used for the formulation of water-based drilling fluids on their performances as filtrate reducers or cuttings dispersion inhibitors. The dependence of properties of bentonite/polymer/electrolyte systems on polymer molecular characteristics has been studied. The results indicate that polymer dimensions which depend on both salinity and polymer molecular weight have a major influence on the efficiency in inhibiting cuttings dispersion. Filtration properties of the investigated model fluids have been found to be strongly dependent on polymer/bentonite interactions : an increase in molecular weight of polymeric additives can induce clay particle flocculation resulting in poor filtration control whereas an increase in polymer negative charges improves bentonite dispersion and thus filtration properties. Une étude de laboratoire a été entreprise pour évaluer l'influence exercée par les paramètres structuraux des systèmes polymère/électrolyte couramment utilisés pour la formulation de fluides de forage à base d'eau sur leurs performances en tant que réducteurs de filtrat ou inhibiteurs de dispersion des déblais. Les relations entre les propriétés des systèmes bentonite/polymère/électrolyte et les caractéristiques moléculaires du polymère ont été étudiées. Les résultats montrent que les dimensions du polymère qui dépendent à la fois de la salinité et du poids moléculaire ont une influence majeure sur son efficacité à inhiber la dispersion des déblais. On a constaté que les propriétés de filtration des modèles de fluides étudiés dépendent fortement de l'interaction polymère/bentonite : une augmentation du poids moléculaire des additifs polymères peut entraîner une floculation des particules argileuses provoquant un mauvais contrôle de filtration, alors qu'une augmentation des

Au sein du collège les enseignants vivent en direct la nécessaire adaptation de leur projet pédagogique à la spécificité des élèves et à la différenciation de leurs actes. Ces enseignants, entre deux rives, ont au quotidien à la fois, à conduire leur activité, à auto évaluer celle-ci et à construire des pratiques efficaces.

Ces procédures sont en interaction avec la construction chez l’enseignant d’un sentiment d’auto-efficacité qui, au-delà de renforcer l’estime de soi, est un véritable moteur de la valorisation et de la production des actes d’enseignement.In their day to day work, teachers are required to make decisions, evaluate the positive elements in their environment and mobilize resources in order to organize their pedagogical activity.

    Congenital dysplastic aortic syndromes range from coarctation at the aortic isthmus to more extended aortic disease (midaortic syndrome). The latter is usually restricted to dysplastic aortic segments of up to 15 cm. Long segment dysplasia of the entire abdominal or thoracic aorta is extremely rare. This case of a 30-year-old patient with a very long segment congenital thoracoabdominal aortic coarctation and infrarenal aortobi-iliac and cavobi-iliac aplasia represents to our knowledge the most extended congenital vascular malformation in a surviving adult patient. The developed extensive collateral pathways ensured the survival of the patient, so that the main clinical manifestation was a refractory hypertension. Because of the extent of the disease, open surgery represented the only viable option. Interestingly, after 30 years of uncontrollable hypertension, the patient's blood pressure promptly responded to surgical treatment. A concomitant infrarenal aplasia of both the aorta and cava vein is also very unusual and points to a major developmental deficit during vascular embryogenesis. Copyright © 2015 Elsevier Inc.

    Bone marrow aplasia observed following ionizing radiation exposure (Total Body Irradiation; gamma dose range: 2-10 Gy) is a result, in particular, of the radiation-induced (RI) apoptosis in hematopoietic stem and progenitor cells (HSPC). We have previously shown in a baboon model of mobilized peripheral blood CD34{sup +} cell irradiation in vitro that RI apoptosis in HSPC was an early event, mostly occurring within the first 24 hours, which involves the CD95 Fas pathway. Apoptosis may be significantly reduced with a combination of 4 cytokines (4F): Stem Cell Factor (SCF), FLT-3 Ligand (FL), thrombopoietin (TPO), and interleukin-3 (IL-3), each at 50 ng{center_dot}mL{sup -1} (15% survival versus <3% untreated cells, 24 h post-irradiation at 2.5 Gy). In this study we show that addition of TNF-{alpha}(800 IU/ml) induces an increase in 4F efficacy in terms of cell survival 24 h after incubation (26% survival after 24 h irradiation exposure at 2.5 Gy) and amplification (k) of CD34{sup +} cells after 6 days in a serum free culture medium (SFM) (k{sub CD34{sup +}} = 4.3 and 6.3 respectively for 4F and successive 4F + TNF-{alpha}/4F treatments). In addition, the 4F combination allows culture on pre-established allogenic irradiated stromal cells in vitro at 4 Gy (k{sub CD34{sup +}} = 4.5). Overall this study suggests (i) the potential therapeutic interest for an early administration of anti-apoptotic cytokines with or without hematopoiesis inhibitors (emergency cytokine therapy) and (ii) the feasibility in the accidentally irradiated individual, of autologous cell therapy based on ex vivo expansion in order to perform autograft of residual HSPC collected after the accident.

    To report the combined hysteroscopic and laparoscopic treatment of a complete septate uterus with unilateral cervical aplasia (class U2bC3V0/ESHRE/ESGE classification) and isolated mullerian remnants. Step-by-step presentation of the surgical treatment (Canadian Task Force classification 4). Complete septate uterus with unilateral cervical aplasia (formally Robert's uterus) is characterized by the presence of a uterine septum completely dividing the endometrial cavity into an obstructed hemicavity and a contralateral nonobstructing hemicavity connected normally to the existing cervix. It has always been described as isolated without any associated anomaly. A 30-year-old woman was referred to our department for dysmenorrhea and primary infertility. Hysterosalpingography showed the presence of a right (RT) hemiuterus with a patent fallopian tube; further evaluation with 2- and 3-dimensional ultrasound and magnetic resonance imaging showed an externally normal-appearing uterus, a right normal hemicavity connected normally with the existed cervix and, a left hemicavity fully divided from the right one by a complete septum and not connected with the cervix. Interestingly, a peculiar complex mass with cystic areas, attached posterolaterally from the left side to the uterine wall at the level of the isthmus and the upper cervix, was also diagnosed. The study protocol was approved by our local institutional review board. During outpatient hysteroscopy, a right uterine hemicavity with a single ostium was identified without any communication with the left hemicavity. The patient was then scheduled for combined laparoscopic and hysteroscopic treatment. During laparoscopy, a normal uterine body with multiple myomas and a pseudocystic lesion attached posteriorly and left laterally to the uterus at the level of the isthmus and the upper cervix were shown; no communication between the cystic part of that lesion and the isthmus or the cervicovaginal canal was observed.

    The patient was a 47-year-old man diagnosed as having autoimmune hemolytic anemia (AIHA) in April 2011. He also had a congenital chromosomal abnormality, a balanced translocation. Treatment with prednisolone (PSL) 60 mg/day resulted in resolution of the AIHA, and the treatment was completed in November 2011. While the patient no longer had anemia, the direct and indirect Coombs tests remained positive. In May 2013, he developed recurrent AIHA associated with acute pure red cell aplasia (PRCA) and hemophagocytic syndrome (HPS) caused by human parvovirus B19 (HPV B19) infection. Tests for anti-erythropoietin and anti-erythropoietin receptor antibodies were positive. Steroid pulse therapy resulted in resolution of the AIHA, PRCA, as well as HPS. The serum test for anti-erythropoietin antibodies also became negative after the treatment. However, although the serum was positive for anti-HPV B19 IgG antibodies, the patient continued to have a low CD4 lymphocyte count (CD4, <300/μL) and persistent HPV B19 infection (HPV B19 DNA remained positive), suggesting the risk of recurrence and bone marrow failure.

    Full Text Available Two cases of Aspergillosis in immunocompromised children are reported. Both were caused by Aspergillns flavus. Early diagnosis and treatment led to the remission of the process. One patient had acute myeloid leukemia; the fungus was isolated from the blood. The other patient with bone marrow aplasia, presented an invasive aspergillosis of the paranasal sinuses with dissemination of fungal infection; the diagnosis was obtained by histology and culture of biopsied tissue from a palatal ulceration.No presente trabalho são registrados dois casos de aspergilose em crianças imunocomprometidas. O estudo micológico completo identificou Aspergillus flavus como agente dos dois processos. A presença cada vez mais frequente da aspergilose invasiva deve-se ao número crescente de pacientes imunocomprometidos, muitos com hemopatias graves submetidos à quimioterapia. O diagnóstico precoce em um dos casos possibilitou remissão do processo. Tratava-se de paciente com leucemia mielóide aguda, tendo sido isolado o fungo do sangue circulante. O segundo caso evoluiu para óbito, com infecção fúngica generalizada.

    Full Text Available Trois expérimentations ont été conduites de 1996 à 1998 au niveau de la prise d'eau de l'usine hydroélectrique de Camon, sur la Garonne, de manière à tester l'efficacité d'un exutoire de surface destiné aux smolts de saumon atlantique. Ce dispositif de dévalaison est situé en rive gauche, au niveau du plan des grilles. Son efficacité a été évaluée par la méthode de marquage-recapture et le comportement des smolts dans le canal d'amenée a été suivi grâce à la technique de radio-pistage. L'efficacité initiale du dispositif est apparue faible en 1996 (moyenne de 34 % . Le suivi par radio-pistage a révélé que l'emplacement de l'exutoire n'était pas responsable de sa faible efficacité, les poissons stationnant préférentiellement à proximité. Cependant, la présence d'une ascendance masque son entrée. Suite à la mise en place d'une grille de tranquillisation et de platelages horizontaux au niveau de l'entrée de l'exutoire, cette efficacité a été portée à une valeur moyenne de 73 %. De bonnes conditions hydrauliques générales dans le canal d'amenée associées à une hydrodynamique locale favorable aux environs immédiats de l'entrée de l'exutoire s'avèrent indispensables à l'obtention d'une efficacité satisfaisante du dispositif de dévalaison. L'utilisation d'un éclairage nocturne intermittent a non seulement eu un effet sur le comportement des smolts dans le canal d'amenée en maintenant ces derniers dans les zones directement éclairées mais aussi sur les rythmes d'entrée des poissons dans l'exutoire, les passages apparaissant principalement en début d'extinction. La capture de 7 715 salmonidés sauvages a permis d'étudier les rythmes de dévalaison au niveau d'un obstacle. Les pics journaliers de passage semblent liés principalement à de forts débits et/ou à une augmentation de la température de l'eau. L'activité de dévalaison au niveau d'un obstacle apparaît en outre essentiellement

    Full Text Available Une expérimentation a été conduite en 1996 au niveau de l'aménagement hydroélectrique de St. Cricq (gave d'Ossau dans le but de tester deux dispositifs de dévalaison destinés à éviter le passage dans les turbines des smolts de saumon atlantique (Salmo sala L.. Le premier, localisé au barrage, consiste en une barrière acoustique répulsive destinée à détourner les smolts vers un clapet de décharge. Le champ sonore, généré par 16 émetteurs immergés, est dans la gamme de fréquence 100-600 Hz avec un niveau sonore maximal de 120-130 dB. Le deuxième dispositif, localisé à l'usine, consiste en un exutoire de surface situé en rive, à proximité immédiate de la grille de prise d'eau. L'efficacité des deux dispositifs a été évaluée par marquage-recapture et le comportement des smolts a été suivi par radiotélémétrie. Les passages de smolts par le clapet du barrage varient de 20 % à 60 % ; cette efficacité résulte essentiellement du débit élevé transitant par le clapet. Les tests effectués avec et sans barrière acoustique n'ont mis en évidence aucun effet significatif du champ sonore. L'efficacité de l'exutoire du bassin de mise en charge est d'environ 80 %. La faible largeur de la prise d'eau (11 m, le faible espacement des barreaux de la grille de prise d'eau (2,5 cm, les conditions hydrauliques devant la grille qui guident rapidement les poissons vers l'entrée de l'exutoire, et la configuration de l'entrée de l'exutoire qui crée un écoulement à faible gradient de vitesse peuvent expliquer l'efficacité élevée de ce dispositif.

    Full Text Available Pour réduire le coût et assurer un comportement relativement plus ductile pour des éléments en béton armés renforcés, l’addition des fibres de verre pourrait être considérée comme solution de rechange, puisqu’elles sont relativement plus déformables et meilleur marché que la fibre de carbone. Dans ce sens, le travail actuel vise à évaluer l’efficacité du renfort externe sur les poutres renforcées par le tissu de FRP (verre-carbone. Un total de sept poutres en béton armé a été renforcé en flexion et en cisaillement, et testé sous un chargement quatre points cyclique statique. Les champs des contraintes et de déformation ont été contrôlés par un système de caméra numérique “Gom-Aramis”. Les résultats ont été analysés en termes de résistance, rigidité, ductilité et mode de rupture. To reduce the cost and to ensure a behavior relatively more ductile for concrete strengthening elements, the addition of glass fibers could be regarded as solution of replacement, since they are relatively more deformable and cheaper than carbon fiber. In this sense, current work aims at evaluating the effectiveness of the external reinforcement on the beams strengthened by fabric of FRP (glass – carbon. Seven concrete beams reinforced were strengthening in bending and shearing, and were testing under four point cyclic static. The fields of the stresses and deformation were controlled by a numerical system of camera “Gom-Aramis”. The results were analyzing in term of resistance, rigidity, ductility and mode of failure

  6. One-Dimensional Modelling of Polymer Flood Performance. Analytical and Graphical Solutions Modélisation de l'efficacité du déplacement unidimensionnel par injection de polymères. Solutions analytiques et graphiques

    Full Text Available A graphical method for simulating linear polymer flooding is proposed. The method is based upon the analytical solution of Darcy's law and continuity equation which describe the two-phase, one-dimensional, incompressible flow of oil and polymer solution through the reservoir rock. Continuous polymer injection and polymer slug injection are considered. Several physical mechanisms determining microscopic displacement efficiency are taken into account: resistance factor, residual resistance factor, retention composed by adsorption and mechanical entrapment, and inaccessible pore volume. Other properties are not considered: mixing and dispersion, shear and thermal degradation. This analytical-graphical model closely reproduces linear laboratory oil displacement experiments. Consequently, it can be used by the Field Engineer to rapidly estimate the additional oil recoverable by a linear polymer flood. On propose dans cet article une méthode graphique de simulation de l'injection de polymères dans le cas unidimensionnel. Cette méthode est basée sur la solution analytique de la loi de Darcy et de l'équation de continuité qui décrivent l'écoulement diphasique incompressible unidimen-sionnel d'huile et d'une solution de polymères à travers la roche réservoir. On examine l'injection continue et l'injection de bouchons de polymères. On prend en compte plusieurs mécanismes physiques qui déterminent l'efficacité du déplacement microscopique : facteur de ré-sistance, facteur de résistance résiduel, rétention due à l'adsorption et au piégeage mécanique et, enfin, volume des pores inacessibles. On ne tient pas compte des autres propriétés : mélange et dispersion, dégradation mécanique et thermique. Ce modèle analytique et graphique reproduit très directement les expériences de laboratoire de déplacement d'huile en milieu unidimensionnel. II peut donc être utilisé par l'ingénieur de chantier pour une estimation rapide de l

    Full Text Available Cet article présente une analyse de l’usage pédagogique du réseau socio-numérique Facebook comme dispositif d’apprentissage collaboratif à distance dans l’enseignement supérieur, notamment à l’Institut supérieur des études technologiques de Mahdia (Tunisie. Cette recherche qualitative vise à évaluer l’efficacité du travail collaboratif dans le cadre d’une activité d’apprentissage impliquant des étudiants en informatique. Nous tentons à cet effet de déterminer en quoi l’usage de Facebook comme outil de partage, de communication et d’échanges en réseau favoriserait la mise en place d’un processus efficace de co-construction des savoirs et d’interactions entre apprenants. Pour atteindre cet objectif, l’analyse s’appuie sur le paradigme de l’apprentissage social de Bandura (1977 qui met l’accent sur le jeu d’interactions permanentes entre les comportements d’un individu, son fonctionnement cognitif et les variables de l’environnement. Les données issues des traces d’activités sur le mur du groupe Facebook et des contenus d’entretiens semi-directifs ont permis après analyse d’établir que l’utilisation pédagogique de Facebook a effectivement favorisé la coproduction des savoirs attendus chez les étudiants au cours de l’activité. Ainsi, nous sommes parvenus à la conclusion que l’usage de Facebook est efficace pour la mise en place d’une activité d’apprentissage collaborative à distance. Cependant, cela nécessite l’élaboration en amont d’un véritable scénario de formation organisant le déroulement de l’activité.

    Full Text Available Au cours de cette étude est analysée l'influence de l'énergie de surface d'un tambour déshuileur sur son efficacité et sa sélectivité de relevage. Quatre tambours en acier inoxydable, en polychlorure de vinyle, en polypropylène et en dérivé fluorocarboné de tensions critiques de mouillage différentes sont testés comparativement en fonction de l'histoire de leur expositionvis-à-vis de phases hydrocarbure (kérosène et eau. Les essais réalisés montrent que seuls les tambours en dérivé fluorocarboné de très faible tension critique de mouillage s'avèrent intéressants pour des utilisations industrielles. En effet, ils présentent un comportement indépendant de l'histoire de leur exposition ce qui les rend très faciles à utiliser, sans précautions particulières, du fait de leur très grande sélectivité vis-à-vis des hydrocarbures. Par contre, les autres tambours, qui présentent des contributions polaires non négligeables à leur énergie de surface, ont des comportements vis-à-vis des hydrocarbures fonction de l'histoire de leur exposition et ne s'avèrent pas sélectifs vis-à-vis des hydrocarbures à récupérer. The aim of this article is to analyze the influence of the surface energy of a deoiling drum on its gathering efficiency and selectivity. The project consists in testing drums having the same size but made of materials having different surface energies so as to evaluate the influence of this key parameter that had previously been poorly analyzed. Four materials were chosen : stainless steel, polyvinyl chloride, polypropylene, and a fluorocarbon derivative. These materials are representative, a priori, of the behavior of most materials because of the position of their critical wetting tension (gamma c compared to the superficial tension values of water (72 dyn/cm and the hydrocarbon phases to be gathered (25 to 35 dyn/cm (Fig. 1. It should be noted that the fluorocarbon derivative drum tested was patented by

    The theoretical and experimental study of the collection of carriers built up by ionization in standard chambers, is made by varying the value of different acting parameters. In the presence of constant ionization intensity and under a D.C. and A.C. voltage, the effect of geometry, recombination, diffusion and attachment is analyzed. The compensation of thermal neutron D.C. chambers is equally considered. Under a time dependent ionization intensity and D.C. voltage, is then studied the effect of recombination on current response, and on the collection efficiency of all formed charges. (author) [French] L'etude theorique et experimentale de la collection des porteurs crees par ionisation dans les chambres couramment utilisees est entreprise en fonction de la valeur des differents parametres agissants. En presence d'une ionisation constante et sous une tension d'alimentation d'abord continue puis alternative, on analyse l'influence de la geometrie, de la recombinaison, de la diffusion et de l'attachement. La compensation des chambres a courant continu de mesure neutronique est egalement examinee. Ensuite, sous une intensite d'ionisation variable dans le temps et en alimentation continue, on etudie l'effet de la recombinaison sur la reponse en courant et sur l'efficacite de la collection de la charge totale liberee.

Le dispositif de dévalaison est situé en rive droite à proximité immédiate du plan des grilles. Le débit moyen alimentant l'exutoire a varié au cours de l'étude de 0,4 m3/s à 1,2 m3/s ce qui correspond à 1,6 % à 4,3 % du débit turbiné. Lefficacité du dispositif a été évaluée grâce à la technique de marquage-recapture. Le comportement des smolts dans le canal d'amenée a été suivi par radiotélémétrie. L'efficacité de l'exutoire (moyenne : 17 % s'est révélée très faible en 1995 â cause de conditions hydrauliques défavorables. Un mur déflecteur a été mis en place en 1997 afin de modifier l'écoulement dans le canal et améliorer le guidage des poissons vers l'entrée du dispositif de dévalaison. L'efficacité de l'exutoire est passée à 55 %. Le comportement des poissons à l'amont immédiat des grilles de prise d'eau est très dépendant des conditions hydrodynamiques dans le canal d'amenée. L'efficacité de l'exutoire semble croître avec la longueur des poissons, la proportion des classes de taille inférieures à 19 cm étant plus faible sur les poissons piégés que sur les poissons lâchés. Cette sélection est très certainement liée à l'espacement relativement important des barreaux des grilles de la prise d'eau (30 mm qui malgré le courant tangentiel au plan de grilles demeurent plus perméables aux individus les plus petits. L'éclairage de l'entrée de l'exutoire ne paraît pas avoir d'influence sur les déplacements des poissons radiomarqués dans le canal d'amenée, le facteur hydraulique étant prépondérant. Il modifie cependant les rythmes de passage des poissons par l'exutoire.

    L’épidémie du Virus de l'Immunodéficience Humaine en milieu pédiatrique est surtout le résultat de la transmission mère-enfant. Notre étude a pour objectif de décrire l'efficacité de la prévention de la transmission mère-enfant du Virus de l'Immunodéficience Humaine par le protocole OMS 2010 (Option A et trithérapie) au centre médical saint Camille de Ouagadougou. Nous avons mené une étude d'une cohorte d'enfants suivis dans le cadre de la prévention de la transmission mère-enfant du Virus de l'Immunodéficience Humaine au centre médical saint Camille de Ouagadougou sur une période de 2 ans allant du 1er Janvier 2012 au 31 Décembre 2013. Nous avons obtenu l'accord de 4900 femmes enceintes pour le dépistage de l'infection du Virus de l'Immunodéficience Humaine et 238 gestantes ont été diagnostiquées séropositives soit 4,86% de séroprévalence. Les femmes étaient surtout infectées par le Virus de l'Immunodéficience Humaine avec de type I (95,38%)). La majorité était sous trithérapie (74,3%) et (25,7%) sous prophylaxie (option A). Les nouveau-nés (92,5%) ont reçu un traitement antirétroviral à base de névirapine dans les 72 heures après la naissance. L'allaitement sécurisé a été appliquée dans 78% des cas. Le taux global de transmission mère-enfant du VIH était de 3,6% avec 3% de transmission chez les enfants nés de mères sous trithérapie antirétrovirale et 6,3% dans les cas de prophylaxie antirétrovirale. Le facteur de risque de transmission a été le long délai du début d'administration des antirétroviraux chez le nouveau-né. La mortalité infantile à un an était de 3,5%. Cette étude a révélé l'efficacité de l'Option A et conforté celle de la trithérapie, le passage à l'Option B+ serait donc plus bénéfique. PMID:26966499

    Applying DTPA aerosol for the treatment of lung contamination by lanthanum we were able to determine its effectiveness as a function of time. Provided it was administered early during the two hours after exposure, over 50 per cent could be removed using lower therapeutic doses than those prescribed for other routes of administration. Its association with some enzymes did not enhance the chelator therapeutic effect. We also calculated the constant of passage of lanthanum through the alveolar wall and found a value of 0.016 mn{sup -1}. Finally, as we have discovered a large part cannot be mobilized by DTPA, we shall now study the physico-chemical mechanisms involved in this protection. (authors) [French] L'emploi du DTPA en aerosol dans le traitement des contaminations pulmonaires par le lanthane, nous a permis d'etablir et d'evaluer son efficacite en fonction du temps. A condition d'etre utilise precocement, dans les deux heures qui suivent la contamination, une fraction superieure a 50 pour cent peut etre eliminee et ceci avec des doses therapeutiques inferieures a celles preconisees pour les autres voies d'administration. L'association avec quelques autres enzymes n'a pas permis d'ameliorer l'effet therapeutique de ce chelateur. Nous avons egalement chiffre la constante de passage du lanthane a travers la barriere alveolaire dont la valeur est de l'ordre de 0.016 mn{sup -1} Enfin, la decouverte d'une importante partie non piegeable par le DTPA nous amene maintenant a etudier les mecanismes physico-chimiques de cette protection.

    Full Text Available Dans le présent article, nous faisons état de la variabilité selon le captureur de l'efficacité de répulsifs à base d'huiles végétales appliquées sur la peau contre les piqûres de Simulium damnosum s. l. Les expérimentations ont été effectuées en zones de savane (Chaussée-Niaka et de forêt (Soubré de Côte d'Ivoire. Les formulations (lotions, crèmes] testées lors de ces travaux ont été obtenues à partir d'huiles d'amande de palme (Elaeis guineensis, de coco (Cocos nucifera et de gobi (Carapa procera. La technique classique de capture sur homme à l'aide de tubes à hémolyse en matière plastique a été utilisée. Pour chaque journée d'expérimentation, un captureur non traité (jambes non enduites de répulsif servait de témoin. Les résultats indiquent qu'en savane, quels que soient le répulsif et le captureur, la densité simulidienne se situait de 1 à 4, 1 à 6 et de 2 à 10 simulies par homme et par jour lorsque le captureur était respectivement protégé avec le coco, le palmiste et le gobi. Avec les mêmes répulsifs, en zone de forêt, l'agressivité simulidienne variait de 9 à 16, de 2 à 30 et de 8 à 49 piqûres par jour. En comparaison, le témoin recevait de 67 à 90 et de 310 à 533 piqûres par jour, respectivement en zones de savane et de forêt. Malgré les variations importantes dans le nombre de simulies capturées en fonction du captureur choisi, nos résultats montrent que quels que soient le répulsif et l'espèce simulidienne, une protection similaire est conférée à tous les captureurs. Ils indiquent également que le recours à des substances naturelles locales, utilisées comme répulsifs en application dermique, est l'une des meilleures méthodes de protection personnelle contre les simulies.

    Full Text Available This paper describes a faculty development model called the highly relevant mentoring (HRM model; the model includes a framework as well as some practical strategies for meeting the professional development needs of faculty who teach web-based courses. The paper further emphasizes the need for faculty and administrative buy-in for HRM and examines relevant theories that may be used to guide HRM in web-based teaching environments. Of note is that HRM was conceived by the instructional design staff who contributed to this paper before the concept of high impact mentoring appeared in the recent literature (2009. While the model is appropriate in various disciplines and professions, the examples and scenarios provided are drawn from a Canadian university’s experience of using HRM, in conjunction with a pedagogical approach called ICARE, in a variety of nursing courses and programs. Cet article décrit un modèle de formation du personnel enseignant intitulé « highly relevant mentoring (HRM » (mentorat haute efficacité; ce modèle comprend une structure et des stratégies pratiques visant à combler les besoins en formation du corps professoral d’une faculté offrant des cours en réseau. L’article souligne la nécessité d’un appui facultaire et administratif au HRM et étudie les théories pertinentes pouvant servir à guider le HRM dans des milieux d’enseignement en réseau. On notera que le HRM a été conçu par l’équipe de conception de matériel pédagogique qui a contribué à cet article avant l’apparition, dans les publications récentes (2009, du concept de « high impact mentoring » (mentorat à haut rendement. Bien que ce dernier modèle convienne à diverses disciplines et professions, les exemples et les scénarios fournis ici sont tirés de l’expérience d’utilisation du HRM dans une université canadienne, conjointement à une approche pédagogique appelée ICARE, dans une variété de cours et de programmes

    A six-month-old baby with congenital patent ductus arteriosus (PDA), bilateral microtia and canal atresia was referred for hearing assessment. The audiology assessment revealed bilateral profound hearing loss, which is atypical for a case of pure canal atresia. Imaging was performed much earlier than usual and, as suspected, the patient also had bilateral severe inner ear anomaly. It is extremely rare for a person to have both external and inner ear anomaly because of the different embryological origin. The only suitable hearing rehabilitation option for this kind of patients is brainstem implant. However, the parents had opted for sign language as a form of communication.

    la disponibilité d’énergie de traction électrique et la durabilité de la batterie. La conception du système de gestion thermique de la batterie basse tension doit donc prendre en compte les exigences requises de la chaîne de traction et du véhicule, la conception et l’architecture du pack batterie, les contraintes d’environnement, au moindre coût et au moindre poids, etc., tout en optimisant les compromis entre ces paramètres souvent antagonistes. Le processus de conception du thermomanagement de la batterie basse tension de traction fait l’objet de la première partie de cet article. Ce processus sera illustré par deux exemples, l’un mettant en oeuvre l’air en provenance de l’habitacle du véhicule et l’autre, par un refroidissement direct via le circuit de réfrigération du véhicule. Pour une application concrète, le processus de décision doit intégrer l’ensemble des modes de thermomanagement étudiés dans ce contexte et les différents paramètres et exigences pris en compte en tant que données d’entrée. La seconde partie de l’article présente un modèle de simulation thermoélectrique simplifié de la batterie basse tension de traction. Quelques résultats de calculs seront présentés à titre d’exemples dans deux perspectives différentes, d’une part, le dimensionnement thermique du système de thermomanagement, et d’autre part, l’optimisation du bilan énergétique du véhicule. Par ailleurs, ce modèle de simulation simplifié a également permis d’identifier et d’évaluer plusieurs stratégies pertinentes de gestion thermique de la batterie. Ces stratégies visent à améliorer l’efficacité et la performance du véhicule tout en ménageant la durée de vie de la batterie. La troisième partie présente certaines de ces stratégies. Parmi celles-ci, le post-refroidissement et le préconditionnement thermique de la batterie basse tension de traction, en préchauffage par conditions froides et en

    In our therapeutic activity the non-conventional indications represent 5-10% relative to the indisputable indications which the hyperthyroidism in the second half of the life and the differential thyroid cancers are. In this paper our experience since 1966 is revised and confronted with the data of international literature. In the last almost 40 years we have treated 178 hyperthyroidism of which 17 were youngsters between 16 and 20 years old, 17 multi-nodular euthyroid goiters (MEG), 85 advanced cardiopathies and 8 Cordarone cardiopathies. The indications are precise: relapses after ATS or surgery in young subjects, counter-indications or surgery refusal for the MEGs and cardiologic indications. The long term surveillance was managed by an adequate code. Immediate morbidity is null. The efficiency is high in the hyperthyroidism treatment. The hypothyroidism is diagnosed and early treated. The reduction of the MEG mass is significant. An objective amelioration of the heart state was obtained (23%). The evaluation of the preventive effect of induced hyperthyroidism by Cordarone is underway. In conclusion, the enlargement of indications concerns mainly the hyperthyroidism in young subjects. In order to avoid carcinogenic risks we excluded the children under 16 years, excepting for special situations. This extension to the procreation age imposes a rigorous application of contraception and radiation protection instructions and needs a prolonged evaluation of results

    Targeted therapies are now more often used in lung cancer. Inhibitors of EGFR and of angiogenesis have demonstrated a certain activity in this disease. Some experimental in vitro or in vivo studies are in favour of combined targeted therapies and radiation. For example, additive or supra-additive effects have been shown when inhibitors of the EGFR tyrosine kinase were given with radiation. In advanced lung cancer, the combination of bevacizumab with chemotherapy was demonstrated to produce better survival outcomes. But a high rate of fatal hemoptysis was reported with this drug, particularly for central and squamous tumors. This could be a limitation for its use in combination with radiation. Drugs with multiple targets are becoming available; their association with radiation seems to be promising. (author)

    obstruer les lignes de transport et les installations de traitement d'effluents pétroliers. Pour contrôler ces dépôts d'hydrates, on utilise fréquemment, comme inhibiteurs, le méthanol ou les glycols. Aujourd'hui, les équilibres thermodynamiques des hydrates de gaz sont bien connus ; par contre, les cinétiques de formation et de croissance doivent être étudiées afin de mettre en évidence de nouveaux moyens de contrôle grâce à l'étude des mécanismes de formation des hydrates hors équilibre. Le présent travail propose une étude de la cinétique de formation de l'hydrate de méthane dans une boucle de recirculation de laboratoire dans laquelle le mélange liquide, saturé de méthane, circule à une pression maximum de 75 bar. La pression constante au cours des expériences est maintenue par ajout de gaz frais. Dans un premier temps, nous avons étudié les effets de la pression (35-75 bar, de la vitesse d'écoulement du liquide (0,5-3 m/s, de la rampe de refroidissement (2-15°C/h et de la quantité d'hydrocarbure présent dans la charge (0-96 % sur les cinétiques de formation de l'hydrate. Nous proposons ensuite une nouvelle méthode de prédiction, en premier lieu, des conditions thermodynamiques (pression et température correspondant aux valeurs de vitesse de croissance maximum de l'hydrate, puis de ces vitesses de croissance maximum. Nous avons obtenu un bon accord entre valeurs expérimentales et calculées. Enfin, nous avons évalué, en utilisant la procédure expérimentale décrite précédemment, l'efficacité de quelques inhibiteurs cinétiques et tensioactifs mis au point pour éviter, soit la nucléation, soit la croissance des cristaux et l'agglomératon de particules d'hydrates de méthane.

Si fascinantes que soient ses applications – laser, cryptographie, GPS, ordinateur, imagerie médicale –, la physique quantique fait cependant intervenir des paradoxes déroutants pour notre logique ordinaire.

    Images in medicine have to help the doctor in a diagnostic or therapeutic aim. The choice must be made in function of pathology or organ as known (it is not necessary to ask for a computed tomography where we know that only an echography can give the answer to the question we ask ), the criteria must stay the best performance for the cheapest price, but the quality of interpretation is a more important thing. It is important to avoid a lot of examinations which do not give better informations but are heavy to endure for the patients. In conclusion, the aim of this kind of proceedings is to assure to the patients who come confidently to us, the best service at the less constraints price without forgetting that a conclusion depends on a given methodological situation and reminding of beside machines we have not to forget the men.

    Nano-technology can be used to manage and assemble substances in unprecedented ways in the history of products for human health. Underlying this revolution are the possibilities for using new therapeutic processes and separating a drug's various functions (distribution, effects, etc.). This is not possible with classical drugs. Nano-medicine has made it possible to develop new approaches to treating cancer, by using nano-particles with physical effects at the scale of the malignant cell. Hard metallic oxide nano-particles have been designed so that they can play a therapeutic role when activated by x-rays. The x-rays irradiation will free electrons from the metallic oxide, these electrons will lose energy through collisions with water molecules and will create free radicals in the cells. These free radicals are very reactive and will damage the covalent bounds of the molecules located around the nano-particles. Clinical tests on man are expected to begin very soon. These 'x-ray-activable' nano-particles might set off a revolution in the practice of radiotherapy for destroying or controlling malignant tumors

    A real technological revolution has deeply modified the field of application and perspectives of nuclear medicine, and nuclear oncology in particular, during the past 5 years. Diagnostic applications such as positron emission tomography (PET) with {sup 18}F-fluorodeoxyglucose (FDG) have had a significant impact on the diagnostic strategy adopted by medical oncologists, with the addition of invaluable functional data to already available anatomical data provided by conventional imaging modalities. Numerous other {sup 18}F-labeled tracers currently under clinical evaluation have been developed to study various tumor functions (tumor proliferation, hypoxia, hemo-therapy-induced apoptosis, etc.). These tracers may have a considerable impact on therapeutic strategies. Other positron-emitting radionuclides, such as copper-64, iodine-124, and yttrium-86 (whose respective half-lives are 12.7 hours, 4.2 days. and 14.7 hours) will soon be available for certain clinical indications, such as immuno-PET (with monoclonal antibodies or antibody fragments used as carriers) or pretreatment dosimetry, which cannot be performed with fluorine-18 due its short half-life. As far as therapeutic applications are concerned, the use of internal radiotherapy, which has been restricted to thyroid cancer for a long time, was recently extended to other cancers as new carriers, such as monoclonal antibodies (radioimmunotherapy) or peptides (radio-peptide therapy), new targeting methods (pre-targeting), and new radionuclides, especially alpha particle emitters (alpha therapy), became available. These technological advances require that specific radiation safety regulations be implemented to protect nuclear medicine personnel, patients' close relatives, and the environment. Most current regulations concern diagnostic applications with technetium-99m and therapeutic applications with iodine-131. Regulations pertaining to the clinical use of {sup 18}F-FDG were recently enacted (2001). Regarding exposure nuclear medicine personnel, the amount of radioactivity used for therapeutic purposes is currently limited to 740 MBq, which requires that the patient be kept in a shielded room. Radiation exposure can be roughly estimated by measuring the exposure rate (in {mu}Sv/h) delivered at a distance of 1 meter from a source of one MBq. When considering both the exposure rate and half-life, it appears that similar doses of iron-52, yttrium-86, and iodine-124 deliver a high dose rate immediately after injection and during the following few hours. Current regulations on environmental exposure limit radioactivity levels in hospital sewage falls out to 1000 Bq/L, for technetium 99m, and 100 Bq/L, for iodine-131. Forthcoming regulations for other radionuclides should not be established solely based on general rules such as the 100 Bq/L limit. Impact studies similar to those required in the nuclear industry, should be conducted. (author)

    We report a unique anomalous renal venous drainage on a 25-year-old man who had congenital absence of the right renal vein and an aberrant venous drainage through the lower pole of the kidney into the inferior vena cava. To our knowledge, this anomaly has not been previously reported in the peer-reviewed literature. State-of-the-art imaging findings are presented.

    Based on a case report of aplastic anemia associated with malformation, we discuss the diagnostic criteria and the nosologic problem between the 2 principal aplastic anemia accompanied with malformation: Fanconi disease and dyskeratosis congenita. A 19-year-old girl, issued from a third degree consanguineous marriage, was admitted because of anemic and hemorrhagic syndrome. Physical examination showed several malformations: microphtalmia, brownish spots, generalized hyperpigmentation and ungueal dystrophy without mucosal leucoplasia. Statural and ponderal retardation were noted. On the hemogram there was a pancytopenia and on biopsy, the bone marrow was desertic. The caryotype performed on peripheral blood lymphocytes after sensibilisation with mitomycin C revealed chromosomal instability aspects. Based on these clinical and biological features, the diagnosis of hereditary aplastic anaemia was retained. The patient was given norethandrolone. She died 3 months later by septic shock. Coexistence of aplastic anemia with a malformative syndrome suggests most probably an hereditary form of aplastic anemia. Fanconi anemia is the most frequent. It associates characteristic anomalies of the face, with microphtalmia, brownish spots, statural and ponderal retardation, and thumb anomalies. Ungueal dystrophy, mucosal leucoplasia are almost pathognomonic of congenital dyskeratosis. When the malformative syndrome is not characteristic, the cytogenetic study may also fail to make the differential diagnosis, as was the situation in our case.

    A 6 yr old male Yorkshire terrier was presented for an ~6 yr history of progressive cough and dyspnea. Thoracic radiographs revealed a 6 cm diameter mass within the right caudal thorax. Thoracic ultrasound identified an intrathoracic mass ultrasonographically consistent with liver tissue and a chronic diaphragmatic hernia was suspected. Exploratory laparotomy was performed, but no evidence of a diaphragmatic hernia was identified. Thoracic exploration identified abnormal lung parenchyma. The accessory lung lobe was removed using a stapling devise near its base. The consolidated mass had the gross appearance of liver and was histologically identified as ectopic hepatic tissue. Ectopic hepatic tissue, unlike ectopic splenic and pancreatic tissue, is rare and generally has a subdiaphragmatic distribution. This solitary case report demonstrates that ectopic intrathoracic hepatic tissue should be considered a differential diagnosis for a caudal mediastinal mass.

    1979-01-01

    In the first phase of treatment of acute lymphatic leukemia in children (ALL) with aggresive cytostatic protocols, the doctor is, in some patients, forced to modify the antitumor therapy over a certain period of time because of bone marrow depression. The authors attempted to pull patients with ALL through this critical phase of the disease - by administering "profilactically" Lithium Carbonate (Li2CO3) ( in order to stimulate granulopoiesis) or, if anaemia, leukopenia and thrombocytopenia had already occurred, by administering concentrates of erythrocytes, leukocytes and platelets - without discontinuing the administration of cytostatics. The results of these attempts are reported.

    External apical root resorption is an adverse effect of orthodontic treatment. It reduces the length of root and breaks the integrity of teeth and dental arch. Orthodontics is the only dental specialty that clinically uses the inflammatory process to correct the mal-aligned teeth. Hence, it is necessary to know the risk factors of root resorption and do everything to reduce the rate of root resorption. Hence, all predisposing factors which are systemic as well as local should be considered be...

    Congenital anomalies of the upper limbs are rare and etiologically heterogeneous. Herein, we report a male infant with non-syndromic bilateral Type Vb ulnar longitudinal dysplasia with radiohumeral synostosis (apparent humeral bifurcation), and bilateral oligo-ectro-syndactyly who was born following an uncomplicated pregnancy, with no maternal use of prescription or illicit medication. Array CGH (60,000 probes) and chromosomal breakage analysis (DEB) were normal. Similar appearances have been reported in children exposed to thalidomide or cocaine, but sporadic patients have also been reported without a prior history of exposure to known teratogens. © 2018 Wiley Periodicals, Inc.

    White Certificate Schemes mandate energy companies to promote energy efficiency through flexibility mechanisms, including the trading of energy savings. They can be characterized as a quantity-based, baseline-and-credit system for the diffusion of energy efficient technologies. This paper compares experiences with White Certificate Schemes in Great Britain, Italy and France, in order to identify the basic drivers of each, and ultimately offer an original interpretation as an adaptive instrument, in the sense that it can take different forms in response to specific institutional contexts. A first analysis shows that Schemes perform well in terms of static efficiency, i.e. they are cost-effective and generate net social benefits over the period considered, though with large discrepancies rooted in different technological potentials. Regarding dynamic efficiency, i.e. the ability to induce and sustain technological change over the long haul, market transformation occurred in Great Britain, but was poorly incentivized in Italy and France by inadequate compliance cost recovery rules. Substantial organizational change has occurred in every country, mainly by strengthening vertical relationships between obliged parties and upstream businesses. Overall, the obligation (rather than the market component) drives the early phases of the Schemes. (authors)

    Full Text Available Following its National Strategy of Justice Reform 2011-2016, the Republic of Moldova has aimed to improve its national laws and practices regarding the effects of foreign arbitral awards. Lately, the code of civil procedure has been amended and the Supreme Court of Justice adopted a decision for a more uniform jurisprudence on the recognition and enforcement of foreign arbitral awards. Being part to the New York Convention of 1958 on the recognition and enforcement of foreign arbitral awards, the Republic of Moldova needs to bring its national law and judicial practice in line with the standards of the international treaty. Also, a favorable legal environment for the international efficiency of the foreign ar bitral awards would respond to the Moldova’s goals to integrate into the international and European trade, which became topical considering the signature of the Association Agreement with the EU and the economic embargos announced by the Russian Federation. This articles aims to assess the conformity of the national law of Repu blic of Moldova with the New York Convention of 158 and to identify the main rules for the recognition and enforcement of foreign arbitral awards within Moldova’s territory.

    Chaque année, des patients décèdent faute d'organes disponibles pour une transplantation. Chacun étant libre de donner ou non ses organes pour le bien d'autrui, l'Etat ne saurait juridiquement contraindre ses concitoyens à faire don d'une partie de leur corps, tant de leur vivant qu'après leur mort. La liberté n'étant pas absolue, la sauvegarde de la santé et de la vie des receveurs potentiels justifie pourtant de mettre sur pied des mesures de promotion du don d'organes à l'attention de la p...

  14. Reduced BMP signaling results in hindlimb fusion with lethal pelvic/urogenital organ aplasia: a new mouse model of sirenomelia.

    Directory of Open Access Journals (Sweden)

    Kentaro Suzuki

    Full Text Available Sirenomelia, also known as mermaid syndrome, is a developmental malformation of the caudal body characterized by leg fusion and associated anomalies of pelvic/urogenital organs including bladder, kidney, rectum and external genitalia. Most affected infants are stillborn, and the few born alive rarely survive beyond the neonatal period. Despite the many clinical studies of sirenomelia in humans, little is known about the pathogenic developmental mechanisms that cause the complex array of phenotypes observed. Here, we provide new evidences that reduced BMP (Bone Morphogenetic Protein signaling disrupts caudal body formation in mice and phenocopies sirenomelia. Bmp4 is strongly expressed in the developing caudal body structures including the peri-cloacal region and hindlimb field. In order to address the function of Bmp4 in caudal body formation, we utilized a conditional Bmp4 mouse allele (Bmp4(flox/flox and the Isl1 (Islet1-Cre mouse line. Isl1-Cre is expressed in the peri-cloacal region and the developing hindimb field. Isl1Cre;Bmp4(flox/flox conditional mutant mice displayed sirenomelia phenotypes including hindlimb fusion and pelvic/urogenital organ dysgenesis. Genetic lineage analyses indicate that Isl1-expressing cells contribute to both the aPCM (anterior Peri-Cloacal Mesenchyme and the hindlimb bud. We show Bmp4 is essential for the aPCM formation independently with Shh signaling. Furthermore, we show Bmp4 is a major BMP ligand for caudal body formation as shown by compound genetic analyses of Bmp4 and Bmp7. Taken together, this study reveals coordinated development of caudal body structures including pelvic/urogenital organs and hindlimb orchestrated by BMP signaling in Isl1-expressing cells. Our study offers new insights into the pathogenesis of sirenomelia.

    Bone marrow graft failure and poor graft function are frequent complications following hematopoietic stem cell transplantation and result in significant morbidity and mortality. Both conditions are associated with graft versus host disease (GVHD), although the mechanism remains undefined. Here we show in two distinct murine models of GVHD (complete MHC- and class II-disparate) that mimic human peripheral blood stem cell transplantation that Th1 CD4+ cells induce bone marrow failure in allogeneic recipients. Bone marrow failure following transplant of allogeneic naïve CD4+ T cells was associated with increased CD4+ Th1 cell development within bone marrow and lymphoid tissues. Using IFNγ-reporter mice, we found that Th1 cells generated during GVHD induced bone marrow failure following transfers into secondary recipients. Homing studies demonstrated that transferred Th1 cells express CXCR4, which was associated with accumulation within bone marrow and spleen. Allogeneic Th1 cells were activated by radiation-resistant host bone marrow cells and induced bone marrow failure through an IFNγ-dependent mechanism. Thus, allogeneic Th1 CD4+ cells generated during GVHD traffic to hematopoietic sites and induce bone marrow failure via IFNγ-mediated toxicity. These results have important implications for prevention and treatment of bone marrow graft failure following hematopoietic stem cell transplantation. PMID:23523972

  16. Gene therapy strategy to reduced bone marrow aplasia: evaluation in cynomolgus macaque exposed to a gamma total body irradiation

    The aim of this work was to assess whether direct intra-marrow injection of an adeno-viral vector expressing human IL-1α gene stimulates hematopoiesis in healthy non-irradiated and gamma irradiated cynomolgus macaques. In the first hand, we have evaluated the feasibility of this gene therapy strategy in two healthy non-irradiated macaques. In this work, we have observed an increase of neutrophil, monocyte and platelets in the two animals treated with the therapeutic construct. This effect was associated with no abnormal clinical side effect. On the other hand, we have evaluated this strategy in non-human primate exposed to a sublethal gamma irradiation. Two of three animals treated by the therapeutic construct reduced significantly the neutropenia, thrombocytopenia and anemia radio-induced. In conclusion, this gene therapy strategy gave a similar clinical benefit comparatively to systemic administration of huIL-1α but without severe side effect. (author) [fr

    The brachytherapy in the treatment of rhabdomyosarcomas of the nasogenian groove has to be discussed when it exists a residual tumor after an initial chemotherapy and leads to good results, in term of local control. An advantage of the brachytherapy in comparison with external irradiation, in the treatment of children tumors, is the small size of the treated volume, that allows to decrease the aftereffects incidence. The brachytherapy comes in the frame of a therapeutic needing a multidisciplinary approach and a cooperation between surgeons, brachy-therapists and onco-pediatricians. (N.C.)

    Abnormalities in children exposed to radiation during gestation occur more specially when the mother irradiation is made between the third and the eleventh week of pregnancy. However a case is reported through a child irradiated in utero and whom development is normal. So, more than a proposition of abortion to the parents it would be convenient to propose a long term surveillance by pediatricians and register these cases in a national data base, this rounding up of knowledge will allow to consolidate the advices that could be given to the parents on taking any precaution in this particularly difficult context.

    Actually the radiotherapy that concerns 50% of anti tumoral treatments is accompanied by side effects. The evolution of this therapy turns towards the limitation of the early effects but also the delayed effects in order to improve the quality of life of patients. The first answer was to reduce the radiation doses and the irradiated volume. Three directions are to be kept in mind concerning the digestive tissues: Fight against the break of the epithelial homeostasis by increasing the pool of cells before irradiation and by facilitating the processes of restoration and epithelial regeneration by the stimulation of the proliferation of the cells of progenitor compartments; Fight against the phenotype changes of the cells, and more globally against the cellular activation and its consequences: activation of the vascular endothelium and the initiation of the inflammatory and thrombosis processes; activation of the vascular smooth muscular cells and stenosis; oxidative stress and tissue hypoxia; recruitment and activation of the mesenchyme cells and matrix unbalance; to consider the global nature of the secondary effects, and become aware that there is, besides the physical twilight connected to the irradiation configuration, a biological twilight, that is to say a potential repercussion of the irradiation effects out of the field, on the global nature of an organ even an organism, and this in the therapy and accident configurations.

    The treatment of soft tissue sarcomas of limbs should be discussed within an experienced multimodality team. Surgical resection remains the cornerstone of therapy for localized disease and achieves a five years overall survival around 75% and a local recurrence rate as low as 10% in the best series. In complex cases, neo-adjuvant treatments may be used such as systemic chemotherapy, isolated limb perfusion, or radiotherapy to achieve an optimal conservative approach. Molecular genetics of sarcomas and quality of margins are essential to guide diagnosis and therapeutic selection. In case of marginal or incomplete resection, a new enlarged surgical resection should always be discussed before administration of any adjuvant treatments. Many retrospective studies and two randomized studies (one of adjuvant brachytherapy and one of external beam radiotherapy) have shown that adjuvant radiotherapy after complete surgery significantly reduces the risk of local recurrence in extremity soft tissue sarcomas. A randomized study has compared pre- to postoperative radiotherapy. The results in terms of local control are similar in both arms. The risk of surgical complications is higher in the preoperative arm and the risk of late sequelae is higher in the postoperative arm. A randomized study within the French sarcoma group is ongoing evaluating the omission of postoperative radiotherapy in favourable cases. Presently, the role of systematic first-line invasive treatment (including surgery and/or radiotherapy) of desmoids is debated. It is becoming evident that up to 50% of patients with desmoids benefit from a front-line non-aggressive policy, because growth arrest is a common feature of this disease. Additional study of the molecular determinants of desmoid behaviour is needed to guide treatment. (authors)

    This thesis deals with the synthesis of phosphorus molecules towards anticancer therapeutics. A simple method which allows the tri-alkyl-phosphines oxides synthesis radiolabelled by phosphorus 32 has been established, with a satisfactory specific activity for biological studies on animal model. A increase of the specific activity seems to be possible from the point of view of a human therapy utilization. Results on healthy mice are very hopeful. An original method to obtain N substituted amino-phosphonic acid esters, by reaction of an organo-borane with an azido-alkyl-phosphonate, has been tested. A simple method for the hydrolyze of esters phosphonic functions by the dichloro-boranes, has also been developed. (A.L.B.)

    Purpose We retrospectively analyzed anatomo-clinic, therapeutic and progressive particularities of 74 young patients (= 20 years) with nasopharyngeal carcinoma treated between 1993 and 2005. Patients and methods Initial work-up included a fiberoptic naso-fiberscopy with biopsy, computed tomography and/or MRI of nasopharynx and neck, chest X-ray, abdominal ultrasonography and bone scan. Patients were treated with either primary chemotherapy (epirubicin and cisplatin) followed by radiotherapy or concomitant radio chemotherapy (five fluorouracil and cisplatin). Radiotherapy was delivered to a total dose of 70 to 75 Gy to nasopharynx and involved cervical lymph nodes and 50 Gy to the remainder cervical areas. Results The median age was 16 years. Sixty-three percent of patients had undifferentiated tumors. Sixty-six percent had locally advanced tumor. With a median follow-up of 107 months, one patient presented a local relapse, 24 patients developed distant metastases with a median delay of 7 months. The 5 years overall survival and disease-free survival were 66 and 65 %. Late complications were dominated by dry mouth and endocrine disorders. Comments Pediatric nasopharyngeal carcinoma is characterized by an early metastatic diffusion. Local control is excellent but with severe late toxicities. New techniques of radiotherapy and new molecules of chemotherapy could improve these results. (authors)

    This document analyzes the impact of the choices made by all actors, from the energy producers to the process and infrastructure designers and the end users, in the evolution of energy consumptions. Some very little improvements made in the energy efficiency of appliances can become equivalent to the production of several oil fields or power plants at the world scale. More efficient energy uses will not replace the additional productions but they must be considered together to be compared. The energy files are first analyzed as a whole in order to show the hidden field of energy choices. In this framework, users, designers and fitters have to face very different choices because they consider efficiency improvements under different aspects: scientifical, technical, economical and social (public information and habits). These differences in efficiency uses have a time and spatial impact on the growth of energy consumption. The economical and social factors influence the collective way to consume energy and are expressed by the energy intensity of the economic activity. The last part of this document analyzes the influence of this notion on the world energy consumption scenarios at the 2050 prospects. (J.S.)

    The Co-op Agrilait de St-Guillaume is located at near Drummondville, Quebec. The facility employs 160 people to produce 3 million kilograms of cheese annually. In addition, 21 million litres of whey are produced. This sub-product of cheese is turned into powder to make ice cream, protein shakes, energy drinks, and feed for animals. The cost of transforming whey had gone up over the last five years, which also cut into the operating budget. Whey transformation also consumed large amounts of well water. In order to address these challenges, the energy consumption of the facility was evaluated in an effort to lower the energy costs by 30 per cent, lower water consumption and reduce water pollution. The study identified and measured the energy consumption for each activity related to the whey transformation process. The equipment and procedures used in the facility were subsequently modernized and the air quality in the facility was also improved. The improvement in whey transformation rendered the facility profitable again. The project was financed by capital loans over a ten year period, and the money saved during the first year was over $400,000. The money saved over the next 10 years will be more than 2 million dollars. 5 figs.

    Full Text Available The objective of this research is to identify the determinants of the effectiveness or the economic inefficiency of corn producers in the oases of Kanem in Chad. From a stochastic border of production, we estimate and break up into technical and allocative effectiveness, the levels of economic effectiveness. The factors responsible for the inefficiency were highlighted by the estimate of a Tobit model to take into account the truncated character (0 or 1 of the dependent variable (effectiveness. The analysis of the values of estimated parameters of 251 farmers in 2014 showed that production inputs affected significantly the production cost. More precisely, the price of fertilizers, herbicides, total equipment and labour are the factors highly influenced the production cost of corn.  As a whole, the indices of allocative effectiveness vary from 48.6 % to 95.1 %. The average allocative effectiveness is 80.5 % and the economic effectiveness of the production of corn indicates a variable level between 43.6 % and 83.4 % with an average of 55.8 %. In general, these various results obtained on the effectiveness show that in the oases of Kanem, exist still reserves of productivity to develop in order to increase the production of corn and to increase the income of the producers. As for the analysis of the determinants of the technical and economic effectiveness, it showed that the variables such as sex, age, principal activity (agriculture improve the technical and economic effectiveness of the corn producers in the zone of research.

    The Four Points Hotel is located in Toronto and possesses 296 rooms. The annual budget devoted to energy costs was 460 500 dollars. In 1998, the hotel management team met with an energy management team to devise an energy efficiency plan. Approximately one year later, renovation and upgrading work began with the help of the Energy Innovators Initiative from the Office of Energy Efficiency, Natural Resources Canada. The electricity bill represented 73 per cent of the annual energy budget of the hotel. Therefore, lighting seemed like a logical starting point. Each of the 2 700 lamps in the building was replaced with energy efficient lighting. Lighting levels were maintained, and were even improved, as was the case in the interior parking garage. The heating boiler was replaced by an energy efficient one, on the advice of the energy efficiency team. Five heating, ventilation, and air conditioning systems located on the roof, were replaced by energy efficient systems which optimized the ventilation in the hotel. Energy costs were down, as well as the maintenance costs, and the reliability was greatly improved. Energy management is centrally controlled by a computer system called LONWorks. The customers have the possibility of setting their room thermostat between 19 and 24 Celsius. The biggest advantage of the system is the wireless communication between the main building and the parking garage. The parking garage therefore benefits from the same control system without the additional costs associated with the installation of cables. At the start, the expected energy savings were 20 per cent. The management team discovered that the energy savings were more in the order of 35 per cent. In other words, it means 653,000 kWh of electricity and 878,530 hours in gas savings. The first seven months after the completion of the work yielded 52,680 dollars in savings. The hotel business represents a sector where energy efficiency yields big savings, in addition to helping the country meet its goals in terms of climate change. Additional information on the Energy Innovators Initiative is available from Natural Resources Canada.

    Full Text Available New Criteria to Judge Stove Efficiency in the Charcoal Combustion. The water boil test efficiency for choosing the most economic stove in combustion is estimated on the basis of four stoves. In addition to the heating and boiling energy usually considered as selection criterion, other criteria such as the boiling time and the combustion rate have been taken to indicate efficiency. Strangely, it appeared that the stove which maintains water at its boiling point for a long time and has the lowest combustion rate doesn 't valorize fuel energy efficiently if you only keep to the heating and boiling energy. The cooking test made it possible to explain that apparent contradiction : the fuel energy fraction which doesn't enter in the calculation of the heating and boiling energy isn't really lost. A low combustion rate associated with a long boiling time proved to be the best criteria of choosing the most economic stove in fuel. Therefore, the only water boil test doesn't make it possible to identify the most economically efficient stove. Resorting to the cooking test is compelling.

However, as practitioners, have we ever thought of comparing them? In the present article, we will first compare these two types of reading by considering 20 possible differences. This comparison will lead us to a question: how can we help the second language reader to be more efficient when reading on screen? Suggestions will be made based on ideas drawn from introspective verbal protocols collected during an experiment involving eight French-speaking undergraduate students who were met on an individual basis and who were asked to read a hypertext in English. Pragmatic avenues for practitioners will be suggested. At the turn of the twenty-first century, when an increasing number of undergraduate students must cope not only with hypertext reading but also with a second language, being acquainted with ways of helping them is becoming essential.

    Full Text Available In order to evaluate the efficacy of 11 cereal herbicides on no till soft wheat, two trials were conducted in Chaouia region during 2014-2015 growing season. Dominant species of weed flora in Sidi El Aidi site were: Bromus rigidus, Lolium rigidum and Avena sterilis. Dominant species of weed flora in Ouled Said site were: Avena sterilis, Centaurea diluta and Papaver rhoeas. The obtained results showed that “Pyroxsulam” and “Mesosulfuron Sodium + Iodosulfuron sodium” gavethe best efficacy on rip gut brome. Prosulfocarb provided excellent control of ryegrass but no effect on ripgut brome or wild oat. Broadleaf herbicides provided moderate to good control. “Mesosulfuron Sodium +Iodosulfuron sodium” need to be completed with an broadleaf herbicide in case centaurea diluta is present. “Pyroxsulam” need to be tank mixed with a broadleaf herbicide to widen its weeds spectrum. Treatment with “Pendimethalin”as pre-emergence herbicide allowed an early complete control of weeds and good crop selectivity.

    Full Text Available Maize is a very susceptible crop to early competition of weeds. The use of post sowing and pre-emergence herbicides is a mandatory to reduce the impact of weeds on the crop. Two trials were conducted, under irrigation regime, during the growing season 2013-14 in Loukkos on a sandy soil and in Gharb on a clay soil. Weed flora recorded in trials sites was composed of 19 species belonging to 14 botanical families. Based on % cover of each species, Cyperus rotundus, Polygonum convolvulus and Urtica urens were dominant in Loukkos, however, Beta macrocarpa, Chrozophora tinctoria and Amaranthus blitoïdes were dominant in Gharb. All tested herbicides were selective of maize and Integrity, Lumax, Guardian, Prowl and Primextra efficacies on weed species were excellent. However, Dual Gold gave good efficacy on broadleaved species. As grasses,Paspalum distichum was tolerant to all herbicides, Digitaria sanguinalis was well controlled by all tested herbicides. Prowl and Dual Gold failed to control Phalaris brachystachys. The species susceptibility to herbicides varies with the herbicide. Thus, the number of species not controlled (on 19 varies from 1 to 4. The maximum failure was observed with Dual Gold and the minimum with Lumax, Guardian and Primextra.

    Acoustic enclosures and hoods are widely used to reduce machine noise in industrial workshops. Unfortunately these devices are never entirely soundproof, and this noise leakage tends to reduce their overall efficiency. Theoretical models exist for predicting the acoustic behaviour of slits in enclosure panels by calculating the amount of energy transmitted and describing the spatial distribution pattern (directivity) of the radiated sound field. This paper briefly examines two of these models which are simple to use for practitioners working on the `sound-tightness` of enclosures, and proposes technical solutions for reducing noise transmission through most types of commercial enclosures at the design stage: sealing compounds, flaps and profiled seals, noise baffles, acoustically absorbent materials, reactive mufflers.

    Vinches, Ludwig

    Manufactured titanium dioxide nanoparticles (nTiO2) enter into the formulation of several commercial products including cosmetics, paints, varnishes or food. An increasing number of people will be exposed to nanoparticles (NP), in particular, scientists during their research and workers in companies. As such, they are an emerging source of hazard. Indeed, an increasing number of studies are warning against their likely harmful effects on health. The International Agency for Research against Cancer has classified nTiO2 as being possibly carcinogenic to humans. Furthermore some studies have shown that the skin is not an impervious membrane to the NP and that NP penetration is possible when the skin is injured by abrasion, after repeated flexions or even intact. Therefore, dermal protection will be necessary in order to thoroughly protect NP users. Based upon the precautionary principle, gloves should be used as protection against chemicals. However, to the best of our knowledge, no study on their resistance towards NP has been conducted. In this study, the performance of protective gloves was evaluated with respect to nTiO2 solutions and powders, under conditions simulating occupational use. Mechanical deformations, simulating those produced by hand flexing, were applied to nitrile and butyl rubber and latex samples that were in contact with nTiO2 in water, in propylene glycol or in powder form. nTiO 2 penetration through the protective gloves was determined after deformations of the materials. Following these results, the physicochemical and mechanical phenomena that facilitate the penetration of nTiO2 were identified and studied. It was shown that mechanical deformations caused both damage to the sample surface but also a change in the degree of crystallinity of the glove material. Strain energy was also measured. It decreased significantly in presence and absence of nTiO2, indicating a weakening of the polymer chains. A qualitative study showed that repetitive deformations also lead to a decrease in the size of the agglomerates that were contained in the nTiO2 powder. Glove materials that were in contact with colloidal solutions produced a swelling phenomenon. Finally, measurements of the elongation of glove samples immersed in colloidal solutions were used to determine diffusion coefficients across the materials. The transport of the nanoparticles was driven by that of the carrier liquid (water or propylene glycol). Given the carrier solutions and nanoparticles could be transported through the gloves, exposure to skin could occur.

    Lead causes damage to the body by inducing oxidative stress. The sites of damage include the bone marrow, where marrow hypoplasia and osteosclerosis may be observed. Leaves of Carica papaya, which have antioxidant and haemopoietic properties, were tested against the effect of lead acetate in experimental rats. The rats were divided into 8 groups; control, lead acetate only, Carica papaya (50 mg and 200 mg), post-treatment with Carica papaya (50 mg and 200 mg) following lead acetate administration and pre-treatment with Carica papaya (50 mg and 200 mg) followed by lead acetate administration. The substances were administered for 14 days. The effects were evaluated by measuring protein carbonyl content (PCC) and glutathione content (GC) in the bone marrow. Histological changes in the bone marrow were also observed. The results showed that Carica papaya induced a significant reduction in the PCC activity and significantly increased the GC in the bone marrow. Carica papaya also improved the histology of the bone marrow compared with that of the lead acetate-treated group. In summary, Carica papaya was effective against the oxidative damage caused by lead acetate in the bone marrow and had a stimulatory effect on haemopoiesis.

    Full Text Available A 9-year-old female received a double allogeneic stem cell transplant (SCT from an ABO-incompatible HLA-matched sibling for β-thalassemia major, without achieving a complete donor chimerism. Subsequently, the patient received autologous SCT and five donor lymphocyte infusion, without increasing donor chimerism. After the double transplant failure, we performed an unrelated transplant from a full-matched umbilical cord blood (UCBT. Due to the severe immunosuppression of the patient, we did not administer any conditioning regimen nor GVHD prophylaxis. On day +40 after UCBT, trilinear engraftment was documented. Surprisingly, the hematopoietic reconstitution was related to the re-expansion of the autologous (β-thalassemic hematopoietic stem cell, as documented by chimerism studies on both peripheral blood and bone marrow. At present, 30 months after UCBT, there is stable hematopoietic autologous reconstitution. This is the first description of the restoration of autologous hematopoiesis obtained with cord blood infusion in a thalassemia-major patient after a double transplant failure.

    The sparing of viable hematopoietic stem and progenitor cells located in underexposed bone marrow territories associated with the relative radioresistance of certain stem cell populations is the rationale for autologous cell therapy consisting of ex vivo expansion of residual cells after collection postirradiation. The feasibility of this treatment mainly depends on time constraints and hematopoietic cell threshold. We showed in this study that in the absence of early-acting mobilizing agent administration, subliminar amounts of CD34{sup +} cells can be collected (1 x 10{sup 6} CD34{sup +} cells/100 mL bone marrow or for 1 L apheresis) from 6-Gy {gamma} globally irradiated baboons. Residual CD34{sup +} cells were successfully expanded in serum-free medium in the presence of antiapoptotic cytokine combination (stem cell factor + FLT-3 ligand + thrombopoietin + interleukin 3, 50 ng/mL each, i.e., 4F): K{sub CD34{sup +}} = x2.8 and x13.7 (n=2). Moreover, we demonstrated the short-term neutrophil engraftment potential of a low-size mixed expanded graft (1.5 x 10{sup 6} final CD34{sup +}cells/kg) issued from the coculture of unirradiated (20%) and 2.5-Gy in vitro irradiated (80%) CD34{sup +} cells on an allogeneic stromal cell layer in the presence of 4F. Further preclinical research needs to be performed to clearly establish this therapeutic approach that could be optimized by the early administration of antiapoptotic cytokines. (author)

    The E coil highly expressing rhIL-6 constructed by our department was fermented and rhIL-6 products were extracted and purified. The specific activity of the purified rhIL-6 products reached 4.83 x 10 8 IU/mg. The rhIL-6 products were used to treat BALB/c mice injured by 60 Co irradiation for six days (2 μg/big/each). The results showed that the bleeding time, coagulation time and prothrombin time of the rhIL-6 treatment group were significantly shorter than those of the control group (P<0.01), the platelet count and WBC increased by 130% and 165% in the treatment group as compared with the control, the numbers of CFU-Mix cultured in vitro and CFU-s in spleen were significantly higher than those in the control group (P<0.01). These results suggest that rhIL-6 exerts beneficial effects on the recovery of mice from radiation-induced injuries of hematopoietic stem/progenitor cells, and thus helps recovery from radiation injury of bone marrow and hematopoietic function.

    This clinical report describes the fixed prosthodontic rehabilitation of an infra-occluded primary molar. Diagnostic considerations included the patient's age, occlusal status, condition of the infra-occluded tooth including the degree of infra-occlusion and root resorption, as well as adjacent alveolar bone levels. Due to the patient's young age, an invasive prosthetic approach was delayed in favor of an onlay restoration, which represented a more rapid and conservative therapeutic choice. The treatment involved the design and fabrication of a composite onlay on the deciduous molar using a ceramic optimized polymer on a fiber-reinforced composite framework. Three years later, intraoral radiography showed satisfactory marginal adaptation. No change was observed in periodontal tissues.

    Purpose: to evaluate the prognosis value of the PET with F.D.G. in the intermediary therapy evaluation of Hodgkin lymphoma after four chemotherapies, in comparing different criteria of interpretation. Conclusions: our study confirms the excellent negative predictive values of the PET at four chemotherapies in the Hodgkin lymphoma, with different evaluated criteria. The positive predictive value is low with the three methods but PET was decision-making in this series whom 27% of patients were transplanted. The positive predictive value was however higher according to the Gallamini criteria, showing the increased risk of recurrences in this group, even after a graft. (N.C.)

    The therapeutic potential of bone marrow-derived human mesenchymal stem cells (h.M.S.C.) has recently been brought into the spotlight of many fields of research. One possible application of the approach is the repair of injured tissues arising from side effects of radiation treatments and accidents. The first challenge in cell therapy is to assess the quality of the cell and the ability to retain their differentiation potential during the expansion process. Efficient delivery to the sites of intended action is also necessary. We addressed both questions using h.M.S.C. cultured and then infused to Non Obese Diabetes/Severe Combined Immunodeficiency (N.O.D./S.C.I.D.) mice submitted to total body irradiation. Further, we tested the impact of additional local irradiation superimposed to total body irradiation (T.B.I.), as a model of accidental irradiation. Our results showed that the h.M.S.C. used for transplant have been expanded without significant loss in their differentiation capacities. After transplantation into adult unconditioned mice, h.M.S.C. not only migrate in bone marrow but also into other tissues. Total body irradiation increased h.M.S.C. implantation in bone marrow and muscle and further led to engraftment in brain, heart, and liver. Local irradiation, in addition to T.B.I., increased both specific homing of injected cells to the injured tissues and to other tissues outside the local irradiation field. M.S.C. may participate to restoration of intestinal homeostasis 3 days post abdominal irradiation. This study suggests that using the potential of h.M.S.C. to home to various organs in response to tissue injuries could be a promising strategy to repair the radiation induced damages. (author)

    Delayed radiation enteritis is an intestinal fibrosis induced by accidental or therapeutic radiation for pelvic and abdominal cancer treatments. Studies of molecular mechanisms involved in the development and maintenance of fibrosis have showed the respective contribution of CTGF, low TGF-{beta}1 concentrations and Rho/ROCK pathway. Thus, based on the relationship between CTGF, TGF-{beta}1 and Rho pathway, 2 therapeutics strategies have been develop. First, a pravastatin curative gift leads to a fibro-lysis involving an inhibition of Rho and in cascade a reduction of CTGF expression and extracellular matrix deposition. The data suggest that reversal of established radiation fibrosis in the gut is possible. Second, a pravastatin prophylactic gift prevents the installation of a chronic fibrosis but does not protect the tumor. On the base of these results, the radiation therapy department of the Institut Gustave Roussy will soon initiate 2 clinical trials. (author)

    This dossier gathers a series of short articles about energy security and efficiency in a context of policy transition. The first paper deals with the use of international standards to promote energy efficiency thanks to efficient public policies and private sector actions. This was the main topic of the mixed workshop organized by the International electrotechnics Commission (IEC) in spring 2009. The second paper presents the new strategic analysis of the European commission in the domain of energy which stresses on the '20-20-20' climate change proposals approved in December 2008. A new European action plan for energy security and solidarity defines 5 domains requiring an extra action to warrant a sustainable energy supply. The commission is also examining the challenges that Europe will have to face between 2020 and 2050. The third article treats of the security of natural gas supplies which represents a quarter of the European Union (EU) energy mix. The supply crises susceptible to occur may have serious economic and social consequences. Therefore, the EU must be prepared to warrant its security of supplies. Cogeneration allows the EU to stay close to its energy goals. Buildings play a key role in the realisation of the EU's energy saving objectives and fight against climate change. The new directive on buildings energy efficiency (2002/91/CE) will allow to exploit this potential of saving and to stimulate sustainable investment and employment as well. Finally, the publication of the second WBCSD (World business council for sustainable development) international report on buildings energy efficiency has led GDF Suez utility to reaffirm its commitment in favour of energy saving and efficiency.

    The melanoma is an invasive pathology for which no treatment is efficient on the disseminated form. The works of the Laboratory aim to conceive molecules presenting a specific affinity for the melanoma by targeting the melanin. The aim of this project is to evaluate for the mouse, the anti tumoral effect of vectorized {sup 131}I by the tracer ICF01012 that presents a durable and specific tumor concentration adapted to an application in internal vectorized radiotherapy. Conclusions: A significant anti tumoral effect of the internal vectorized radiotherapy using the compound {sup 131}I-ICF01012 is demonstrated on two models of melanomas whatever their aggressive potential is. This effect is associated to a inhibition of the tumor cells dissemination towards lungs. The optimization of the therapy protocol is running in order to get a maximal therapy efficiency associated to a controlled toxicity of non-targeted pigmented organs. (N.C.)

    Full Text Available Efficiency of Estrous Synchronization and Artificial Insemination in Azawak Cows: Interest of the Progesterone Profile. For a few years, the sperm of selected Azawak bull has been used in artificial insemination (AI on the local bovine races of Niger, to improve the potential of production. Two methods of estrous and ovulation synchronization are compared: vaginal spirals PRID (Progesterone Vaginal Intra Device and intra muscular injection of GnRH (Gonadotropin Releasing Hormon. For this purpose, seven and six Azawak Females were successively used by treatment. AI were carried out twice at 56 h and 68 h for the PRID, and 20 h and 44 h for the GnRH, after stop of the treatment. Heats appearance was controlled by direct observation during the 7 days following the end of the treatment. Blood were carried out for ten females (5 of each batch three times per day from J9 to J16, then once daily until J27, and finally at twice-weekly intervals during the 5 weeks which followed, in order to establish a profile of plasmatic progesterone by animal. In addition, a pregnant diagnosis was carried out per transrectal palpation, three months after AI. For each of the two treatments, three females expressed estrus, including two before the first AI, and the third later (1 and 5 days respectively for the PRID and GnRH. The increase of plasmatic progesterone rate of these two cows, occurred in the two days after the first AI, with a pregnant on both for the PRID, and two for GnRH. The three whose heats were not noted, were not pregnant in both cases, and had an increase in the plasmatic progesterone rate 3 and 8 days after the first AI respectively for the PRID and GnRH. In conclusion, we did not observe a difference in the answers of two treatments. Moreover, the females without estrus observed, were showed a normal cycle (by the progesterone profile but with late ovulations that have not allowed fecundation. These results suggest us once more, to make the first IA as of the appearance of heats, and in addition, to inseminate only on heats observed.

    Radiotherapy-induced emesis depends on the site of irradiation, the field size and the dose per fraction and is generally less intense than chemotherapy-induced emesis. Established anti-emetic drugs offer only limited symptom control (50%). Ondansetron, a 5HT[sub 3] receptors antagonist, had proven a complete or a major control efficacy (0-2 emetic episodes) of 68 to 95% in three pilot studies (fractionated, single-dose and total body irradiations). In controlled studies, ondansetron efficacy was significantly higher than placebo, metoclopramide and prochlorperazine. The treatment was well tolerated in the different studies.

    An efficient ventilation system provides a good indoor air quality by eliminating air pollutants and ensuring a satisfactory air renewal. Unlike most research works that deal with test cells with controlled boundary conditions, our study focuses on ventilation efficiency in a real environment. In situ experiments are performed and provide the boundary conditions necessary for CFD (Computational Fluid Dynamics) computations. Using CFD for predicting indoor air quality in a real environment is thus analyzed. The influence of permeability on numerical predictions quality is shown. Unfortunately, it is difficult to quantify accurately the air leakages and their airflow rates. Our study proposes a simplified model that includes air infiltration rates in the CFD computations, and that yields satisfactory results. A critical analysis of ventilation efficiency indices is then performed. It is shown that it is currently impossible to evaluate the air change efficiency ( a e ) in an occupied zone. Concerning the air pollutants removal effectiveness, it is shown that the usual index C e is not suited to ventilation systems with variable airflow rates. For such cases, a new formulation of this index is given. The ratio between the airflow rate and the nominal airflow rate of the ventilation system is also taken into consideration. A coupled analysis of this new index and of this airflow rate ratio enables us to assess the air pollutants removal effectiveness while considering the energetic cost of ventilation. We finally show that there is no universal index. The choice of the index depends on the pollutant, on the pollutant concentration, and on the airflow rate. A tool of decision-making aid is thus proposed in order to evaluate the air pollutants removal effectiveness for various ventilation systems. This tool is flexible and rather simple to use. (author)

    Platelet life-span was studied in 165 patients (including 25 children) with chronic idiopathic thrombocytopenic purpura (of at least one year duration) using 111 indium-oxinate-labeled autologous platelets. The site of platelet destruction was not correlated with age, severity of the disease or presence of immunologic anomalies; this site was characteristic of each individual and remained unchanged in a given patient when the test was repeated several times. Splenectomy was performed in 79 patients (at the discretion of physicians who elected splenectomy in 63% of patients with splenic destruction versus 26% only of patients with hepatic destruction). A very close correlation was found between site of destruction and efficiency of splenectomy. However, 13% of initially improved patients developed a recurrence. Spontaneous improvement was seen in only 8 of the non-splenectomized patients with long-term follow-ups (1-5 years).

    Context. - The 'Standards, Options and Recommendations' (SOR) collaborative project was initiated in 1993 by the Federation of the French Cancer Centres (FNCLCC), with the 20 French Regional Cancer Centres, several French public university and general hospitals, as well as private clinics and medical specialty societies. Its main objective is the development of serviceable clinical practice guidelines in order to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review, followed by a critical appraisal by a multidisciplinary group of experts. Draft guidelines are produced, then validated by specialists in cancer care delivery. Objectives. - Produce technical practice guidelines for the brachytherapy of prostate cancer using the methodology developed by the Standards, Options and Recommendations project. Methods. - The FNCLCC and the French Urology Association (AFU) first designated the multidisciplinary group of experts. Available data were collected by a search of Medline and lists selected by experts in the group. A first draft of the guidelines was written, they validated by independent reviewers. Results. - The main recommendations are: 1/ Brachytherapy with permanent seeds alone is a possible curative treatment for prostate cancer patients with the following prognosis factors: tumour stage T1 or T2a (TNM 1992), Gleason score {<=} 6 and PSA < 10 {mu}g/L. 2/ Combined treatment with brachytherapy and hormonal therapy could be more efficient than brachytherapy alone for prostate cancer patients with Gleason score > 7 and/or PSA > 10. 3/ Combination of brachytherapy and external beam radiation therapy can be proposed to prostate cancer patients with intermediate prognosis. 4/ Before and after seed implantation, risks of infection must be prevented by appropriate antibiotic therapy (recommendation). 5/ Brachytherapy must not be performed within 2 months of trans-urethral prostate resection. 6/The height of the urethra receiving more than 200 of the prescribed dose must be reported. The portion of the rectum receiving 100 and 120 % of the prescribed dose must be limited to 10 and 5 mm length, respectively. (authors)

    This study is part of the International Energy Agency Annex 35, 'Hybrid Ventilation in New and Retro-fitted Office Buildings', also called the HybVent Project. It presents the numerical analyses of a number of hybrid ventilation systems and their potential for several buildings in relation to local climate characteristics. The first part of this work reviews the state-of-the-art of existing ventilation systems and details the principles, expectations and features of hybrid ventilation systems. This first section also examines some examples of hybrid systems extracted from the collection of Annex 35 case studies. A comprehensive bibliography of numerical tools available for this type of analysis is given in the second section. The numerical models for building simulation and the object-oriented environment used to develop our simulation tool are presented in this section as well. Two single-zone studies undertaken in this project are reported in the third section. The first study concerns an experimental cell simulation. Numerical results are compared to experimental data to validate the use of the simulation tool developed. The second single-zone study predicts the potential of a specific hybrid ventilation system in a typical classroom, given climatic conditions. Finally, the last section presents a more complete study - a multi-zone study of the Tonga school, an Annex 35 case study located in Sweden. Three rooms were modelled initially to compare numerical results to experimental data and then to analyse the performance of the existing hybrid ventilation system and two other systems. This final study was completed for three European cities with very different climates. The overall analysis of the potential of the hybrid ventilation systems considered and the perspective for future work are outlined in the conclusion. (author)

Senegal is known to have very tow rainfall with high probability of drought occurring du ring crop development. The study on the growth of maize under water deficit conditions aimed at characterising its agro-physiological responses and the evaluation of its water use efficiency (WUE. A water deficit was applied respectively during the vegetative phase (T1, at flowering start (T3 and both during the vegetative phase and at flowering start (T2 with a period of rewatering between these two phases. For the control (TO water was applied by irrigation to maintain optimal water conditions for growth. The amount of water to complete (in low rainfall conditions during the cycle was determined by measuring "bac" evapotranspiration and using crop coefficient (Kc for maize during the different phases. The results show that Synthetic-C variety was sensitive to water deficit during the flowering phase. Actually, the relative water content (RWC, leaf water potential and crop water stress index (CWSI were less sensitive to water deficit during the flowering phase than during the vegetative phase. These parameters showed a higher rate of decrease during the vegetative phase. On the other hand, gazeous exchanges [stomatal conductance (Gs and transpiration (Tr] were found to be more sensitive to water deficit during the reproductive stage. Moreover, significantly low grain yield and WUE were observed during this phase of development. However, on the basis of physiological parameters and productivity, Synthetic-C showed a good capacity to resume its physiological activities after rewatering during the vegetative phase, similar to a good plasticity of the control.

    Environmental monitoring at wind turbine arrays is needed before, during and after project development. Pesca Environmental evaluates the impact of proposed wind turbine arrays on birds and chiroptera by examining their migration patterns through visual and auditory observations during the springtime reproductive and nesting season as well as in the autumn. In order to complete a feasibility study, spring migration patterns of birds and chiroptera must be documented and characterized. In addition to building an inventory of birds and chiroptera, Pesca examines bird behaviour and flight patterns and nesting locations. figs.

    Full Text Available Efficiency of the Ananas comosus (L. Merr. flower induction treatment based on ethylene enriched activated carbon (TIFBio. Pineapple is an important export crop for tropical countries. The flower induction treatments are essential to the pineapple production for economical and social reasons. For conventional agriculture, many chemicals are available but for organic farming ethylene is the only allowed product. A new flower induction method suited to small organic growers has been developed by the Pesticides Initiative Programme of the Coleacp funded by the European Development Fund. The trials conducted proved that the method reaches more than 80% efficiency at 10 weeks for the different application methods evaluated. The wet application trials show a doses response effect as well as effect of the application replication at 2 days interval. The flowering rate culminates at 100% after 8 weeks for the best results, obtained with the wet treatment at 250 mg per plant applied two times at 2 days interval. The different dry treatments tested gave all 85 – 90% flowering rates at 10 weeks, suggesting the presence of an undetermined limitation factor in the conditions prevailing for the trial. The time of application during the day shows no significant effect. It is concluded that the growers can use the TIFBio technique for production control. It is recommended to evaluate the most suited application technique according to their particular case as environmental effect can affect the efficiency.

If this conference succeeds, what means will be the most environmentally and economically efficient while also being socially and politically acceptable? Can market mechanisms help reduce these gases? If so, is that a way for wealthier countries to put of difficult decisions by shifting responsibilities toward poor lands? Would that be ethically acceptable? Does the proposal to rely on market mechanisms not reflect American hegemony ? Might rich countries not curtail aid? What would developing countries think?

    This paper describes, from the current literature, the role of various imaging methods to assess the response to therapy in breast cancer. Two different clinical situations are considered: neo-adjuvant chemotherapy of locally advanced breast cancer and the metastatic breast cancer. Significant clinical data are available for three criteria: the volume of the tumour, the uptake of fluorodeoxyglucose using PET and the perfusion of the tumor evaluated either by dynamic contrast-enhanced magnetic resonance imaging (D.C.E.-MRI) or by PET using {sup 15}O water. {sup 18}F F.D.G. PET allows prediction of the response after one or two cycles of neo-adjuvant chemotherapy. New approaches will offer opportunities to refine the role of imaging in monitoring the response to chemotherapy. PET using thymidine as bio marker is promising in assessing the tissular proliferation. Estrogen analogs could be used to predict hormonally responsive breast cancer. Many other approaches, although less developed, might offer new insights in the response to therapy of breast cancer like magnetic resonance spectroscopy or optical imaging of hemoglobin oxygenation. Imaging also offers potential of monitoring the down-regulation of specialized receptors of the cell membrane in response to treatment: the most studied receptor in preclinical model has been the human epidermal growth factor receptor type 2 (HER2). Integrin, a family of cell adhesion receptor, is also an important target for imaging. Apoptosis, multidrug resistance and hypoxia can also be studied using appropriate bio markers. To allow reliable multicenter trials of new drugs, these different imaging approaches still require an improved standardization of image acquisition and processing. (authors)

    Gauchet, N

    2000-07-01

    This work is within the framework of the studies that are conducted at the IPSN concerning the loss of coolant in a nuclear reactor. During this kind of accident, a spray system in the reactor containment induces the scrubbing of fission products in the atmosphere, and allows the decrease of their concentration in the containment. Our objective is to study the influence of the distance between the drops of their aerosol collection efficiency. This is not taken into account in the existing models. We stimulate the various aerosol collection mechanisms with one free falling drop using computational fluid dynamics codes. The mechanisms are: deposition by brownian diffusion, impaction and interception of the particles by the drop, and collection of particles in the presence of steam condensation at the surface of the drop. These phenomena are studied for drops ranging in diameter from 100 to 700 micrometers, falling in a saturated air-steam mixture whose temperature varies between 20 and 140 degrees Celsius, and total pressure varies between 1 and 5 bars. We validate these models with results available in the literature and with experimental results CARAIDAS. Then we apply these models to the case of three aligned drops, which constitutes a case for which the proximity of the drops has a strong influence on the collection of aerosols. While varying the distance between the drop from 5 to 25 drop diameters, we can highlight the modification of the collection efficiency of each mechanism related to the disturbance of the velocity and concentration fields in the vicinity of the drops. We note that the strongest variations of efficiency observed are in the field of impaction, and that the steam condensation at the surface of the drops limits the decrease. (authors)

    This retrospective study evaluated the efficacy and toxicity of {sup 89}strontium chloride (Metastron - Amersham) in 94 patients with painful bone metastases of prostate cancer (117 injections of 150 MBq) and compared the efficacy of the treatment according to extension of bone involvement, moderate or extensive. The predictive value of Flare response for antalgic efficacy was also studied. Grade III/IV leuko-thrombopenia was observed after only 5% of injections. An improvement of the quality of life was obtained in 65% of cases, a decrease of pain in 78% (31% complete response) and reduction of antalgic intake in 60%. Efficacy was significantly better for pain decrease (p=0,005) and reduction of antalgic intake (p=0,018), and response duration was significantly longer (p<0,0035) in patients with moderate than extensive bone involvement. The Flare response observed in 23% of cases was not predictive of pain response (p=0,0919) and reduction of antalgic (p=0,353). A second dose prolonged antalgic in three-fourth of cases without any apparent increase of toxicity. These results confirm the benefit of {sup 89}strontium chloride for treatment of metastatic bone pain and suggest that internal radiotherapy should be started earlier. A bone scan could be proposed at the time of hormonal escape and bone pain, and internal radiotherapy could be initiated when several metastatic foci exist, even if only one is painful. Thus, pain-free follow up could be prolonged, and transition to other therapeutic approaches, particularly opioids, delayed. (author)

With such a purpose, the ALICE detector is optimized to study the transition toward this hypothetic state of matter. The ALICE's muon spectrometer will measure the muon related probes (quarkonia, heavy flavours...). The first part of this thesis presents the method to calculate the tracking efficiency of this spectrometer. The results, obtained by simulation, are placed in the global efficiency context. They show the evolution of the efficiency as a function of likely electronics failures. They establish that a proper working of the detector involves less than 90% of channels failures and 85% of missing so-called MANU cards.

    Theoretically, the permeance of a fibrous filter decreases with falling pressure. However, few experimental studies have been drawn to verify this theory. Our work has objectively measured the permeance of a fibrous filter to pressures in order of 10 hPa (1 kPa), such that comparisons could be made with the theoretical results. After a literature search of existing knowledge on filtration, we adapted the most advanced theoretical model, the model of S. Payet, for the low-end pressures. Secondly, we developed an original method of experimental measurements for the permeance of a filter, allowing us to twist around the problems associated with aerosol metrology at the lower end pressures. To this effect, we realised a form of tests to completely adapt to these problems. We validated our method by comparing these results to those given by the classic method under atmospheric pressure. Finally, it was possible for us to show the reduction of permeance (and thus the increase of the efficiency) of `formettes` filters for 6 diameters of DOP aerosols, from 4 10-2 {mu} to 0.3 {mu}m, and for filtration velocities between 2 and 40 cm/s. We showed that our experimental results agreed well, according to our theory, up until 50 hPa (5 kPa). (author). 119 refs., 39 figs., 5 appends.

Jatropha curcas oil has an insecticidal activity harnessed by the farmers in Niger. In this study, we compared the insecticidal activity of two batches of oil conserved during 70 days, one exposed to light and the other kept in the dark. The insecticidal efficacy was evaluated in a field with three concentrations (5, 10 and 15% trial on the main pests of Cowpea (Vigna unguiculata (L. Walp and in a laboratory test on Megalurothrips sjostedti Trybon (Thysanoptera: Thripidae with different concentrations of crude oil (50; 100; 150 and 200 µl. No difference in insecticidal effect was found between the two modes of oil conservation, both in the laboratory and in the field. In the field, regardless of the mode of conservation, the concentrations of 10% of J. curcas oil enables a reduction of over than 80% of thrips, aphids, and bugs compared to the control. Its increased seeds yield more than 50%. The concentration of 15% gives an insecticidal effect comparable to that of the reference treatment (deltaméthrine but induces phytotoxicity symptoms on the leaves of Cowpea.

    Radial hemimelia is a congenital abnormality characterised by the partial or complete absence of the radius. The longitudinal hemimelia indicates the absence of one or more bones along the preaxial (medial) or postaxial (lateral) side of the limb. Preaxial limb defects occurred more frequently with a combination of microtia, esophageal atresia, anorectal atresia, heart defects, unilateral kidney dysgenesis, and some axial skeletal defects. Postaxial acrofacial dysostoses are characterised by distinctive facies and postaxial limb deficiencies, involving the 5th finger, metacarpal/ulnar/fibular/and metatarsal. The patient, an 8-year-old-boy with minimal craniofacial dysmorphic features but with profound upper limb defects of bilateral and symmetrical absence of the radius and the thumbs respectively. In addition, there was a unilateral tibio-fibular hypoplasia (hemimelia) associated with hypoplasia of the terminal phalanges and malsegmentation of the upper thoracic vertebrae, causing effectively the development of thoracic kyphosis. In the typical form of the preaxial acrofacial dysostosis, there are aberrations in the development of the first and second branchial arches and limb buds. The craniofacial dysmorphic features are characteristic such as micrognathia, zygomatic hypoplasia, cleft palate, and preaxial limb defects. Nager and de Reynier in 1948, who used the term acrofacial dysostosis (AFD) to distinguish the condition from mandibulofacial dysostosis. Neither the facial features nor the limb defects in our present patient appear to be absolutely typical with the previously reported cases of AFD. Our patient expands the phenotype of syndromic preaxial limb malformation complex. He might represent a new syndromic entity of mild naso-maxillary malformation in connection with axial and extra-axial malformation complex.

    This article described the expansion and modernization of the Centre Hospitalier Universitaire Veterinaire (CHUV) at the University of Montreal. The $74 million retrofit project at the School of Veterinary Medicine began in 2001 and was completed in 2008. The facility is considered to be a forerunner in the agribusiness. The facility can accommodate over 400 students at 3 different types of hospitals for pets, birds of prey, exotic animals, farm animals and equidae. Many challenges were addressed, including indoor air quality which requires specialized control for air temperature, humidity, and rigorous control of the dispersion of contaminants to ensure safety in each space. In addition to reliability, the infrastructure plan had to ensure exemplary energy performance and a reduction in costs. The energy system relies on a combination of electricity, natural gas and heat pumps for heating and cooling the premises. A novel ventilation system was designed to keep the operating rooms free of contaminants and to block contaminants from adjoining rooms. Contagious rooms requiring isolation are kept in slightly negative pressure, and air from these rooms is vented to the outside. It was concluded that the newly modernized facility meets the stringent conditions for thermal comfort in an energy efficiency manner. 3 figs.

  14. Normal Stresses and Interface Displacement: Influence of Viscoelasticity on Enhanced Oil Recovery Efficiency Contraintes normales et déplacement d’interface : influence de la viscoélasticité sur l’efficacité de la récupération assistée

    Full Text Available One of chemical Enhanced Oil Recovery (EOR methods consists in injecting aqueous solutions of polymers into the reservoir in order to improve mobility ratio between the injected fluid and the remaining oil. This “polymer flooding” process is usually only characterized with the low shear viscosity of the injected fluid, even if these aqueous solutions are strongly shear thinning and may show high elastic properties evidenced by normal stresses appearance. In order to study the mechanisms at the interface level, we develop simple model experimentations with the goal of quantifying the influence of viscoelastic properties on fluid displacement in a simple geometry. For this purpose, we propose and characterize a model fluid formulation, for which elastic and viscous effects can be tuned systematically. We study then the displacement of a viscous oil by a Newtonian non elastic, a viscoelastic or a purely shear thinning fluid in a two dimensional flow cell. Observing the shape of the interface between aqueous fluids and displaced oil permits to appreciate viscoelasticity effects on the displacement. Using model geometries and controlled rheology fluids, we show that viscoelastic fluids tend to better displace immiscible liquids than Newtonian fluids and that those effects are closely related to the apparitions of normal stresses independently of shear thinning property or variation of interfacial tension as soon as viscous effects govern the flow. Une des méthodes de récupération assistée du pétrole (EOR - Enhanced Oil Recovery consiste à injecter dans les puits des solutions aqueuses de polymère pour améliorer le rapport de mobilité entre le fluide injecté et le pétrole qui reste dans le puits. Ce procédé de “polymer flooding” est communément caractérisé par la seule valeur de la viscosité à faible gradient de vitesse du fluide injecté, bien que les solutions employées présentent une forte rhéofluidification et également de fortes propriétés élastiques mises en évidence par l’apparition de contraintes normales. Afin d’étudier les mécanismes mis en jeu au niveau de l’interface, nous avons développé des expériences modèles simples pour quantifier l’influence des propriétés viscoélastiques dans le cas d’un fluide déplaçant un autre dans une géométrie simple. A cette fin, nous proposons et caractérisons un fluide modèle avec des composantes visqueuses et élastiques ajustables. Nous étudions ainsi le déplacement d’une huile visqueuse par un fluide Newtonien non élastique, un fluide viscoélastique ou un fluide purement rhéofluidifiant dans une cellule d’écoulement à deux dimensions. L’observation de la forme de l’interface entre la phase aqueuse et l’huile déplacée permet d’apprécier les effets de la viscoelasticité sur le déplacement. En utilisant une géométrie modèle et des fluides aux propriétés rhéologiques contrôlées, nous montrons que des fluides viscoélastiques ont tendance à mieux déplacer un fluide immiscible qu’un fluide Newtonien dans une cellule à deux dimensions et que ces effets sont liés à l’apparition de contraintes normales indépendamment des propriétés de rhéofluidification ou de variation de tension interfaciale dès que les effets visqueux dominent l’écoulement.

    This proposal, focusing on the promotion of end-use efficiency, should be regarded as a necessary instrument to complement the recently adopted legislation on the opening of the internal energy market, which mainly leads to efficiency improvements on the supply side. Memorandum Considering that the functioning of the energy market does not allow ''market forces to allocate economic and natural resources effectively'' and that measures should be taken to improve this, the Commission draws up a list of the main obstacles and presents objectives. The technical potential for savings is at about 40%. The economic cost-effective savings potential is at about 20%, 22% in the buildings sector. The general target is 1 % savings per year. The 1,5 % target in the public sector is therefore more ambitious that the general target. According to the Commission, energy efficiency is a strategy to deal with scarce public funds while at the same time addressing serious energy and climate challenges, using the concept of leadership by example. It presents also the economic impact of energy savings targets and explains the reasons why the local authorities are affected by the proposed directive (Municipalities are energy consumers, the municipalities are energy distributors and/or retailers, the municipalities are planners/investors, the municipalities are motivators and local growth and employment are of concern to local authorities).

    The electricity sector has experienced a slow evolution. Renewable production developments and telecommunications and computers usage will bring major changes with hard to predict effects. Computerized management of production and local storage combined to a certain mastering of the allowed consumption by home automation could improve reliability and the final price for consumers. This change offers great opportunities but also risks of failures, both financial and technical. The regulators have a major role to play in order to understand the concrete gains of the technological propositions and to regulate the investment costs involved. [French] Le secteur de l'electricite a connu une evolution lente.

    Molecular simulation aims at simulating particles in interaction, describing a physico-chemical system. When considering Markov Chain Monte Carlo sampling in this context, we often meet the same problem of statistical efficiency as with Molecular Dynamics for the simulation of complex molecules (polymers for example). The search for a correct sampling of the space of possible configurations with respect to the Boltzmann-Gibbs distribution is directly related to the statistical efficiency of such algorithms (i.e. the ability of rapidly providing uncorrelated states covering all the configuration space). We investigated how to improve this efficiency with the help of Artificial Evolution (AE). AE algorithms form a class of stochastic optimization algorithms inspired by Darwinian evolution. Efficiency measures that can be turned into efficiency criteria have been first searched before identifying parameters that could be optimized. Relative frequencies for each type of Monte Carlo moves, usually empirically chosen in reasonable ranges, were first considered. We combined parallel simulations with a 'genetic server' in order to dynamically improve the quality of the sampling during the simulations progress. Our results shows that in comparison with some reference settings, it is possible to improve the quality of samples with respect to the chosen criterion. The same algorithm has been applied to improve the Parallel Tempering technique, in order to optimize in the same time the relative frequencies of Monte Carlo moves and the relative frequencies of swapping between sub-systems simulated at different temperatures. Finally, hints for further research in order to optimize the choice of additional temperatures are given. (author)

    Full Text Available Divers procédés physiques (mixage, attrition, vibration ultra-sonique ont été utilisés pour désagréger et disperser les argiles d'un sable de gisement. Le traitement aux ultra-sons s'est avéré le plus efficace : après 10 min de vibration on récupère environ 1,5 fois plus de particules fines ( The characterizing of clays is an essential operation for understanding many problems encountered in production. It goes via a preliminary phase in which species are separated quickly and effectively without altering their nature. Chemical processes disperse clays by solubilizing their cements, amorphous compounds and poorly crystallized oxyhydroxides. But they attack fragile species and lead to mistaken results. Therefore, we have chosen various physical processes (mixing, attrition, ultrasonic vibration and compared their efficacy with a reservoir sand. This sand was a quartzose arenite in which 96. 6 % of the grains were between 63 µm and 2 mm. The < 40 µm fine fraction, obtained by wet sieving, represented 2. 44 % of the unprocessed sand, and the clayey fraction (kaolinite, illite, montmorillonite, interstratified illite-montmorillonite was 1. 20%. Mixing was done with a bladed stirer. 40 g of sand and 100 cm³ of demineralized water were stirred for 3 min at a speed of 3000 rpm. Attrition was done by two devices :(1 For attrition by rotation, 400 g of sand and 0. 5 liter of demineralized water were placed in a porcelain jar rotating at a speed of 37 rpm. Tests were performed with water alone and with the adding of a dispersant (0. 3 % sodium hexametaphosphate and a surfactant (0. 6 mole/liter of sodium sulfonate paraoctylphenyl. (2 Attrition by a Turbula TC2 mixer, which gave the jar a complex rotation movement including shaking and rhythmic rocking. 500 g of sand were thus processed in 1 literof 3 % sodium hexametaphosphate solution for varying times. Ultrasonic processing was done with a Sonifer 830 device. The probe was plunged into a suspension made up of 440 g of sand and 300 cm³ of demineralized water processed for times varying from 5 to 100 min. The efficacy of the processing was measured by the weight percent of the < 40 µm fraction. This percentage was 2. 08 % on the average for mixing, 2. 60 % for simple rotation and 2. 87% for rotation by the Turbula device. The adding of dispersant or surfactant had no significant effect. Increasing the rotation time had a minimal effect, in that the percentage of particles recovered went from 2. 21 to 2. 60 % when time increased from 6 to 24 h. Ultrasonic processing was by far the most efficacious and fastest. Indeed, after 5min, an average of 3. 60% of < 40 µm particles was recovered, 4. 10 % after 10 min and7. 18 % after 100 min. The SEM examination of the fractions processed showed that only ultrasonic processing was capable of recovering all of the free clays, either pellicular or trapped in the dissolution cavities or cracks of the quartz grains, i. e. the so-called activeclays. It was also found that this recovery is selective. Montmorillonite and illite are set free at the beginning, while kaolinite is released all during the tests. At the beginning, it was disordered kaolinite, but after 15-20 min of processing, it was ordered kaolinite coming from the microdivision of mica crystals with which it had been associated. This microdivision is clearly visible, moreover, on the cumulative grain-size curve of the < 40µm particles recovered after ultrasonic processing. This curve has two parts:(1 The first part has a steep positive slope linked to the recovery of activeclays. (2 The second part has a much gentler slope linked to the recovery of clayey aggregates and mica and quartz grains microdivided by ultrasounds. The tests performed and a bibliographic study of various processes and operating conditions led us to choose ultrasounds as the process for separating clays from a reservoir sand. The best results were obtained with the following experimental conditions : instrument frequence = 200 kHz, instrument power = 210 W, suspension = 40 g of sand in 300 ml of demineralized water, processing time = 10 min. This quick and efficacious processing preserves the mineral species.

    The functioning of an active sub-slab ventilation system (SVS) has been studied successfully with the help of a previously evaluated numerical model. The parameters explored are the permeability of the sub-slab and the gravel placed beneath it, the amplitude of applied pressure at the installation point of the system and the functioning method: depressurization or pressurization. The mechanisms contributing to the success of the two systems are identified. This numerical study shows that the presence of a layer of gravel beneath the sub-slab considerably improves the performance of the SVS. Considered separately from the extremely permeable sub-slabs, the depressurization systems perform better than the pressurization systems. 17 refs.

We have noted :- With pure dialkyldithiophosphates of different divalent metals (Zn, Cd, Cu, Pb, Ni, Co, prepared from the same alcohol :(a On the four-ball rig, EP results, expressed in terms of load-wear index, show that the highest performances are obtained with ZnDTP, but statistically the higher the ionic radius of the metal, the better the performance. EP results, expressed in terms of weld load, do not show any difference between these MDTP. (b On the four-ball rig, AW results, expressed in terms of wear scar, show that the highest performances are obtaine with ZnDTP; beyond a certain value these performances with Zn and Pb are almost independent of the concentration. For the other metallic DTP, there is a very close relationship between performance and concentration. (c On the FZG gear rig, EP-AW results, expressed in terms of failure load stage and specific wear, show that statistically, the higher the ionic radius of the metal, the better the performance. - With ZnDTP :(a On the four-ball rig, EP results, expressed in terms of load wear index, do not depend on the chemical structure of the alcohol used for synthetized ZnDTP, but if results are expressed in terms of weld load, better performances are obtained with ZnDTP synthetized from secondary alcohols. AW results show that the effectiveness of ZnDTP from secondary alcohols is slightly higher when the alcohols used contain less than six carbon atoms. Beyond six carbon atoms in primary or secondary alcohol molecules, performances decrease. (b On the FZG gear rig, EP-AW results show that performances do not depend on the primary or secondary nature of the alcohols used, and that the smaller the hydrocarbon chain of these alcohols, the better the performances. The results of this work indicate that ZnDTP is the most effective of the MDTP we have studied. For ZnDTP prepared from different alcohols and alkylphenols the performances depend not only on the chemical structure of the additive, but also on contact conditions (kinematic, material types, etc. , and on the criteria considered (seizure load, weld load, wear, etc. Cet article apporte une contribution aux connaissances sur les performances antiusure et extrême-pression des dialkyldithiophosphates métalliques en général, et des dialkyldithiophosphates de zinc en particulier.

    Even if the liberalization of energy markets seems to make it more difficult, it also creates opportunities for the committed local authority. Local authorities fulfill their functions in the energy sphere via a number of roles: as a consumer of energy, as a producer of energy, as a distributor of energy, as a trader of energy, as a regulator, planner and policy maker regarding energy using activities, as an awareness tool of the issues relating to energy use and as a provider of incentives to improve energy performance. There are impacts of liberalization on each of these roles. In most, liberalization has not actually changed what they do, only the degree of attention that should be given to it. Only in those areas where trading is involved are new skills necessary, for instance in purchasing energy, in transporting one own energy and in trading energy. In this framework, the following topics are successively analyzed: Improving performance as an energy consumer, improving performance as an energy producer, improving performance as an energy trader, improving performance as an energy distributor, improving performance in delivering sustainable, energy policies at local level and improving performance as a facilitator and awareness programs.

    Full Text Available Measuring the impact of Public Market Information Systems on market integration and efficiency: an application of the Parity Bounds Model in maize markets in Benin. During the 1990s, agricultural market reforms prevailed within the economic liberalization undertaken in many sub-Saharan countries. In these countries, government intervention in the commodity markets through marketing boards or parastatal organizations was abandoned in favor of new market reforms. Public Market Information Systems (PMIS thus emerged as part of these reforms. Even though great positive impacts were expected from these reforms, little empirical work has been carried out to evaluate their effects. This article investigates how PMIS has affected the market performance of maize, a major staple food crop in Benin. We use a modified version of the Parity Bounds Model (PBM. This method allows the estimation of the rates of spatial market efficiency or integration, but also the estimation of the rates of market arbitrage, autarky, profitable opportunities and the violation of market arbitrage conditions. Results showed that Benin's agricultural sector suffered from a lack of quality training in how to follow the government-supported market information system implemented in the early 1990s. Subsequently, PMIS did not significantly improve the degree of market integration, although the reforms did induce new marketing opportunities. Results also showed that the impact of PMIS is limited by other market imperfections, such as entry barriers for non-residents or for persons not in local informal trade organizations, and the non-transparent enforcement of formal regulations. This study therefore recommends the implementation of more efficiency-raising policies in order to encourage competition and to allow PMIS to fulfill the expectations of farmers and consumers. Improving food producers and traders' access to reliable information will allow them to better exploit the market opportunities induced by the reforms.

    The key issue of the thesis paradox of the weak implementation of economic instruments whereas 1) they are theoretically and also empirically considered as efficient; 2) the market imposes itself as the central reference to modem economies; and 3) economic efficiency is nowadays a legitimacy measure of public policies. Two different answers can be given: either theoretical analysis does not enable to explain the real economic efficiency of a political instrument, or environmental policies do not have economic efficiency as their main objective. The analysis take place in a context of a limited rationality and an inter-temporal consistency of public policies. The purpose is to understand the role of economic efficiency criteria during the adoption, building, and evolution of an environmental policy with an analytical point of view, and not a normative one. The institutional analysis of the American and the French pollution control policies, representative of the implementation of a trading permit system for the first, and of a regulatory instrument for the second, prove that the theoretical analysis of an instrument can not explain a real coordination, but only one organizational form among others. An institutional trajectory is the interpretation of policy instruments of policy instruments from 5 fundamental elements: the nature of the legitimacy of the policy; the nature of the regulator hypothesis on the information; the nature of the decision-making basis; the nature of the collective action. A coordination changes when the occurrence of an event moves one of the fundamental elements, and disorganizes the satisfying equilibrium of the agents. Then, the economic efficiency becomes a negotiation point. A political instrument is adopted for its own ability to solve a dysfunction without disrupting the coordination. (author)

Méthodologie : Une enquête en ligne a été menée auprès d'un échantillon de consommateurs composé de 2 010 Canadiens âgés de 16 à 24 ans. Nous avons réparti les participants de façon aléatoire en six groupes d'étude, et nous avons présenté à chacun des groupes deux des six tVN définis comme conditions expérimentales, selon un plan factoriel 2 × 3 : portion de référence (tVN actuel et portions de référence normalisées pour tous les produits similaires × pourcentage de la valeur quotidienne (% VQ (tVN actuel, ajout des descripteurs « faible/moyen/élevé » et ajout d'un code de couleurs. L'enquête comprenait sept tâches consistant à interpréter, comparer et manipuler, sur le plan mathématique, l'information nutritionnelle figurant dans les tVN. Des modèles de régression de Poisson modifiés ont été élaborés pour chacun des trois résultats. Résultats : La capacité à comparer deux produits similaires s'est révélée significativement meilleure quand le tVN incluait une portion de référence normalisée (p ≤ 0,001 dans tous les cas. L'ajout de descripteurs ou d'un code de couleurs indiquant, sur le tVN, le % VQ pour les calories et les nutriments a amélioré de façon significative la capacité des participants à interpréter correctement l'information à propos de ce % VQ (p ≤ 0,001 dans tous les cas. Le fait de présenter aux participants des portions de référence normalisées et des descripteurs du % VQ a eu un effet modeste sur leur capacité à manipuler, sur le plan mathématique, l'information nutritionnelle pour calculer la valeur nutritive de plusieurs portions d'un produit (ratio relatif = 1,19; intervalle de confiance à 95 % : 1,04 à 1,37. Conclusion : La normalisation des portions de référence et l'ajout d'information sur l'interprétation du % VQ dans le tVN ont permis aux jeunes Canadiens de mieux comprendre et utiliser l'information nutritionnelle. Il faut néanmoins faire preuve de prudence avant de généraliser les résultats de l'enquête à l'ensemble des jeunes Canadiens en raison de l'échantillonnage de la population à l'étude. D'autres travaux de recherche sont nécessaires afin de reproduire cette étude au Canada avec un échantillon plus hétérogène, et en utilisant un éventail de produits alimentaires et de catégories d'aliments.

    Full Text Available La dévalaison des smolts de saumon atlantique (Salmo salar au barrage de Poutès (43 a été suivie en 1989 afin de tester l'influence de la lumière à vapeur de mercure sur le comportement de dévalaison à travers un exutoire de surface destiné à éviter le transit des poissons par les turbines. Les rythmes d'activité quotidienne, nycthémérale et horaire ont été relevés à l'aide d'enregistrement vidéo. L'activité de dévalaison est essentiellement nocturne, sauf en fin de migration où l'on observe un renversement de tendance. Les observations montrent que si l'effet de la lumière est indubitable, le phénomène est complexe car il dépend de l'intensité des lampes, de la durée de l'éclairage et de la situation des lampes par rapport à la zone où l'on désire concentrer le poisson. L'analyse des résultats met en évidence que l'éclairage de l'exutoire augmente significativement les passages des smolts, mais q u e l'effet n'est pas immédiat : une quinzaine de minutes sont nécessaires pour attirer le poisson dans le clapet, le maximum de passage étant observé au bout d'une demi-heure. De trois à huit fois plus de smolts ont emprunté l'exutoire lorsque les lampes étaient allumées.

    Full Text Available Drawing upon police statistics, this paper explores the impacts of the videosurveillance cameras (CCTV installed in November 2014 in the Pâquis neighborhood in Geneva. It focuses on the evolution of criminality within the filmed perimeter and nearby settings. This analysis completes a previous article on the perceived safety of residents (Klauser and Kaenzig, 2017. In line with former studies, our results underline the limited preventive effects of the CCTV system. The analysis shows that cameras are inducing criminality displacement, mainly of drug trafficking. Overall, this study provides a differentiated and complex image of CCTV systems as instruments of territorialization of monitored areas.

    Full Text Available Effectiveness of techniques used to control the development of five invasive amphibious plant species: Crassula helmsii, Hydrocotyle ranunculoides, Ludwigia grandiflora, Ludwigia peploides and Myriophyllum aquaticum. A review. Among rapidly spreading invasive species in Europe, amphibious plants are particularly problematic. These plants are capable of developing a photosynthetic activity both below and above the water surface, and they typically form dense floating populations. Controlling amphibious plants, whether for the purposes of total eradication or for the regulation of their spread, represents an important challenge for managers. A literature review of existing control methods for Crassula helmsii, Hydrocotyle ranunculoides, Ludwigia grandiflora, Ludwigia peploides and Myriophyllum aquaticu was carried out, taking into account efficiency and costs. Of the 87 studies analyzed, a great variation was evident in the research efforts undertaken (number and spatial scale of studies between species and between control methods. However, overall, the different control methods described showed a similar level of efficiency between species. Reports of total eradication of amphibious plants were rare. Such cases resulted from the application of mechanical or chemical methods, most often coupled with complementary methods such as manual finishing. The use of chemical control methods (less laborious and costly than others was found to be frequently documented in the literature. However, except in the case of some active substances, such chemical methods were found to provide low control efficiency. Similarly, to date, biological control has not been found to provide convincing results. In addition, it should be noted that several biological control agents are considered as invasive species in Europe. On the other hand, although little related research has been carried out, methods such as manual or mechanical removal with manual finishing have often been found to result in satisfactory control levels. Aware of the difficulty of controlling amphibious plants, as well as the potential collateral damage caused by control methods to aquatic ecosystems, we argue that consensus still needs to be found between scientists, decision-makers and managers before decisions at regional or national scale can be made.

    Full Text Available The Baller-Gerold syndrome is a rare syndrome with very few cases published in literature. Craniosynostosis and radial aplasia are striking features, easy to diagnose. However, there are many differential diagnoses. Often, the question raised is whether the Baller-Gerald syndrome is a distinct entity. We report a patient with findings of craniosynostosis and radial aplasia consistent with the diagnosis of the Baller-Gerold syndrome. Genotypic heterogeneity could possibly underlie the phenotypic variability exhibited by these cases.

    On February 5, 2003, three years after the creation of an inquiry commission about the Erika tanker-ship wreck, the principle of a new inquiry commission about the safety of maritime transports was decided by the French house of commons. Its mission is: to evaluate the efficiency of the existing measures of prevention of marine pollution by hydrocarbons, to examine if the preconized safety measures for the transport of dangerous or polluting products are effectively enforced, and to evaluate the status of the transposition of the European directives relative to the control of hazardous ships. This document is the first tome of the report made on behalf of this inquiry commission. It comprises four parts dealing with: 1 - the Prestige tanker-ship wreck and the pollution of Spanish and French coasts: similarities with the Erika wreck but differences in the conditions of crisis management, diverging accident analyses, problems encountered in Spain, a significantly improved management of the crisis by the French administration, the public opinion and the local economy, the global increase of maritime transport and the reduction of accidents frequency; 2 - the real improvements after the Erika wreck: the significant advances but their partial implementation, the acceleration of actions following the Prestige wreck; 3 - the expected and realistic perspectives: the sustain of the political will at the national scale, the concretizing of the European decisions and the follow up of the retained trends, the need for more outstanding evolutions at the international scale; 4 - the international liability and compensation regime: its limitation to the hydrocarbons pollution, the lack of victims indemnification in the case of chemical pollution, the need for an increase of the liability of all actors of the maritime transport and the improvement of the compensation system, a community compensation fund to compensate the inefficiencies of the international compensation mechanisms.

    Thrombopoietin (TPO), the major hormone controlling platelet production, has been measured in thrombocytopenias with discordant results. The aim of our work was to assess the value of the TPO assay for differential diagnosis of thrombocytopenias in a large cohort of patients classified according to the results of their platelet isotopic study. We measured TPO (R&D Systems) in serum of 160 thrombocytopenic patients referred to our department for platelet life span isotopic studies. We classified patients as follows: (a) idiopathic or autoimmune thrombocytopenia group (ITP; patients with increased platelet destruction and shortened platelet life span; n = 67); (b) pure genetic thrombocytopenia group (patients with decreased platelet production, normal platelet life span, and without bone marrow aplasia; n = 55); (c) bone marrow aplasia group (BM; patients with decreased platelet production, normal platelet life span, and bone marrow aplasia; n = 13). In patients with pure genetic thrombocytopenia, TPO (median, 55 ng/L) was not different from TPO in patients with ITP (median, 58 ng/L) or controls (n = 54; median, 51 ng/L). Only in patients with bone marrow aplasia was TPO significantly higher (median, 155 ng/L) and negatively correlated to the platelet count (r(2) = 0.5014). Although the median serum TPO is increased in thrombocytopenia with decreased platelet production from bone marrow aplasia, it does not differentiate patients with pure genetic thrombocytopenia from those with ITP.

    Lower limb malformations are generally isolated or sporadic events. However, they are sometimes associated with other anomalies of the bones and/or viscera in patients with constitutional syndromes or disorders of the skeleton. This paper reviews the main imaging features of these abnormalities, which generally exhibit a broad spectrum. This paper focuses on several different bone malformations: proximal focal femoral deficiency, congenital short femur and femoral duplication for the femur, tibial hemimelia (aplasia/hypoplasia of the tibia) and congenital bowing for the tibia, fibular hemimelia (aplasia/hypoplasia) for the fibula, and aplasia, hypoplasia and congenital dislocation for the patella.

    Purpose: Evaluation of MR standard imaging and short time inversion recovery (STIR) imaging to assess changes in red bone marrow cellularity after high-dose chemotherapy (HDC) and peripheral blood stem cells transplantation (PBSCT). Results: STIR sequences demonstrated marked changes in signal intensity not only until the aplasia occurred but also during bone marrow repopulation. An increased signal intensity was observed after HDC in 13/15 patients (87%), followed by a decrease in signal intensity immediately after aplasia in 14/15 patients (93%). Signal intensity further changed parallel to marrow engraftment in 11/15 patients (73%). T 2 -TSE only showed clear changes during repopulation in 8/15 patients (53%). The individual course of the signal in T 1 -TSE was markedly inhomogeneous. Conclusions: STIR sequences show bone marrow edema during aplasia and marrow cellularity during reconstitution and are suitable for characterisation of red bone marrow after HDC and autologous PBSCT.

    A narrow internal auditory canal (IAC) constitutes a relative contraindication to cochlear implantation because it is associated with aplasia or hypoplasia of the vestibulocochlear nerve or its cochlear branch. We report an unusual case of a narrow, duplicated IAC, divided by a bony septum into a superior relatively large portion and an inferior stenotic portion, in which we could identify only the facial nerve. This case adds support to the association between a narrow IAC and aplasia or hypoplasia of the vestibulocochlear nerve. The normal facial nerve argues against the hypothesis that the narrow IAC is the result of a primary bony defect which inhibits the growth of the vestibulocochlear nerve. (orig.)

  6. Tibial developmental field defect is the most common lower limb malformation pattern in VACTERL association.

    Science.gov (United States)

    Castori, Marco; Rinaldi, Rosanna; Cappellacci, Sandra; Grammatico, Paola

    2008-05-15

    VACTERL association is one of the most common recognizable patterns of human malformation and has been recently defined as a multiple polytopic developmental field defect. Limb anomalies are a key component of this condition and characteristically reflect perturbation of radial ray development. However, the pattern of appendicular malformations in VACTERL association is wider and includes a broad spectrum of additional and apparently nonspecific anomalies. We report on the sporadic case of a 4-10/12-year-old boy presenting with multiple costovertebral defects, dextrocardia, bilateral radial ray hypo/aplasia, unilateral kidney agenesis and anal atresia. Homolaterally to the more severe radial ray defect and kidney aplasia, he also has a complex lower limb malformation, consisting of distal tibial aplasia, clubfoot, hallucal deficiency and preaxial polydactyly. Literature review identifies 24 additional patients with VACTERL manifestations and lower limb malformations (excluding cases with isolated secondary deformations). Tibial hypo/aplasia with or without additional tibial field defects, reported in about 2/3 (68%) of the patients, represents the most common finding, while involvement of the fibular ray is rare (20%) and very often accompanies tibial anomalies. The relatively high frequency of tibial ray anomalies in VACTERL patients could easily be explained by the principle of homology of the developmental field theory. Careful search of lower limb anomalies of the "tibial type" is, therefore, indicated in all patients with multiple polytopic developmental field defects. 2008 Wiley-Liss, Inc.
