    Crescentic glomerulonephritis (CGN) has been associated with several solid tumor malignancies. Only a few cases of nephropathy have been reported in association with tubo-ovarian/peritoneal malignancies. We describe a case of 55 years old female who developed combined immune complex-mediated glomerulonephritis and pauci-immune necrotizing crescentic vasculitis simultaneously with the diagnosis of tubo-ovarian/peritoneal cancer. The baseline estimated glomerular filtration rate (eGFR) was 13 ml/min. The patient received two doses of Rituximab and three doses of pulse corticosteroids, leading to significant improvement in renal function and the disappearance of her proteinuria. The eGFR improved to >60ml/min, and her proteinuria gradually resolved after 10 weeks of treatment. She was in a position to be given a combination chemotherapy treatment for tubo-ovarian/peritoneal cancer because of normalization of her CA-125 after three months of therapy.

    Si les manifestations digestives ou respiratoires du reflux gastro-oesophagien sont connues depuis longtemps, la notion de pathologies ORL chroniques ou rĂ©cidivantes liĂ©es au reflux est relativement rĂ©cente et reste sujette Ă  controverse. A travers une revue de la littĂ©rature rĂ©cente, nous avons tentĂ© de mettre en Ă©vidence un lien de causalitĂ© entre RGO et manifestations extra digestives, en particulier ORL, et d’en dĂ©duire une ligne de conduite thĂ©rapeutique.Mots ClĂ©s : RGO, Manifestations extra digestives, Pathologie ORL, Traitement mĂ©dicamenteux, Traitement chirurgical, Traitement coelioscopique

    An Unusual Presentation of Choriocarcinoma in A postmenopausal woman: A case report

    Get PDF
    Choriocarcinoma (CC) is a malignant neoplasm of the trophoblastic tissue, with a potential to metastasize to distant organs. A limited case of gestational CC develops after a long latent period. We describe the case of a 52-year-old postmenopausal woman who developed metastatic choriocarcinoma presumably of gestational origin, 8 years after the last pregnancy, and 2 years after the last menstrual period. The patient was diagnosed with CC metastatic to the brain, spleen, lung and the kidney. The ÎČ-human chorionic gonadotrophin level was found to be raised (1,292,867 mIU/mL). The International Federation of Gynecologic Oncology (FIGO) risk score was calculated to be 14 (very high risk). The patient was initially treated with whole-brain radiotherapy (WBRT) and splenic artery embolization because of a hemoperitoneum. Afterwards the patient received systemic treatment using the standard EMA/CO regimen till complete serological remission. Keywords: Choriocarcinoma; Postmenopausal; Latent period; Brain; Oman

    Managing the Adverse Events Associated with the Combination Pembrolizumab and Lenvatinib Therapy in Endometrial Cancer

    Get PDF
    Endometrial cancer (EC) is the most common gynecological cancer. The combination of lenvatinib plus pembrolizumab has exhibited efficacy as the second line treatment for advanced EC, with a significant benefit in terms of progression free survival (PFS) and overall survival (OS), but the adverse effects (AE) profile is complex. AEs associated with the treatment may represent a limitation to this combination. Here, we report the case of a 38-year-old lady diagnosed with stage IV EC elsewhere, whose disease progressed after the first line of treatment, and was referred to our center in 2021. We treated her with the combination of lenvatinib and pembrolizumab. During the course of the treatment. she developed hand- foot syndrome (HFS) grade III, and hypothyroidism grade II. The AEs were managed with supportive medications, dose interruptions, dose reductions, and multidisciplinary care, which allowed us to continue the treatment. The patient achieved a good partial response, and an ongoing PFS of more than 12 months.

    A potential use for the C-band polarimetric SAR parameters to characterise the soil surface over bare agriculture fields

    Get PDF
    The objective of this study was to analyze the potential of the C-band polarimetric SAR parameters for the soil surface characterization of bare agricultural soils. RADARSAT-2 data and simulations using the Integral Equation Model (IEM) were analyzed to evaluate the polarimetric SAR parameters' sensitivities to the soil moisture and surface roughness. The results showed that the polarimetric parameters in the C-band were not very relevant to the characterization of the soil surface over bare agricultural areas. Low dynamics were often observed between the polarimetric parameters and both the soil moisture content and the soil surface roughness. These low dynamics do not allow for the accurate estimation of the soil parameters, but they could augment the standard inversion approaches to improve the estimation of these soil parameters. The polarimetric parameter alpha_1 could be used to detect very moist soils (>30%), while the anisotropy could be used to separate the smooth soils

    Soil surface moisture estimation over a semi-arid region using ENVISAT ASAR radar data for soil evaporation evaluation

    Get PDF
    The present paper proposes a method for the evaluation of soil evaporation, using soil moisture estimations based on radar satellite measurements. We present firstly an approach for the estimation and monitoring of soil moisture in a semi-arid region in North Africa, using ENVISAT ASAR images, over two types of vegetation covers. The first mapping process is dedicated solely to the monitoring of moisture variability related to rainfall events, over areas in the "non-irrigated olive tree" class of land use. The developed approach is based on a simple linear relationship between soil moisture and the backscattered radar signal normalised at a reference incidence angle. The second process is proposed over wheat fields, using an analysis of moisture variability due to both rainfall and irrigation. A semi-empirical model, based on the water-cloud model for vegetation correction, is used to retrieve soil moisture from the radar signal. Moisture mapping is carried out over wheat fields, showing high variability between irrigated and non-irrigated wheat covers. This analysis is based on a large database, including both ENVISAT ASAR and simultaneously acquired ground-truth measurements (moisture, vegetation, roughness), during the 2008–2009 vegetation cycle. Finally, a semi-empirical approach is proposed in order to relate surface moisture to the difference between soil evaporation and the climate demand, as defined by the potential evaporation. Mapping of the soil evaporation is proposed

    Le kyste de la vallĂ©cule est une malformation laryngĂ©e rare pouvant parfois mettre en jeu le pronostic vital. DiagnostiquĂ© et traitĂ© Ă  temps, le risque de complications et de morbiditĂ© peut ĂȘtre Ă©cartĂ©. Les auteurs rapportent 2 cas de kystes de la vallĂ©cule. La tomodensitomĂ©trie a confirmĂ© la prĂ©sence d’une formation kystique prenant origine au niveau de la vallĂ©cule. Une laryngoscopie directe a Ă©tĂ© faite pour les 2 patients sous anesthĂ©sie gĂ©nĂ©rale. Le premier malade a eu une rĂ©section endoscopique complĂšte du kyste et le 2Ăšme une large marsupialisation au Laser. L’examen anatomopathologique a confirmĂ© la bĂ©nignitĂ© de la formation kystique dans les 2 cas.Mots-clĂ©s : Kyste de la vallĂ©cule, laryngoscopie directe, rĂ©section endoscopique, marsupialisation

    La laryngocĂšle est une pathologie rare. elle est dĂ©finit par la dilatation progressive du saccule laryngĂ©. Le diagnostic est suspectĂ© par l’examen clinique, sa prise en charge est encore discutĂ©e. nous rapportons une Ă©tude rĂ©trospective portant sur 9 patients ayant Ă©tĂ© suivis et traitĂ©s pour une laryngocĂšle. La sĂ©rie a Ă©tĂ© colligĂ©e sur une pĂ©riode de 14 ans, allant de 1998 Ă  2011. Six de nos patients avaient une laryngocĂšle externe, deux patients avaient une laryngocĂšle mixte et un patient avait une laryngocĂšle interne. Une surinfection a Ă©tĂ© notĂ©e chez trois patients rĂ©alisant ainsi le tableau de pyolaryngocĂšle. Tous les patients ont eu un examen clinique complet comportant un examen OrL et cervico-facial ainsi qu’un examen laryngĂ© au nasofibroscope. La tomodensitomĂ©trie cervicale a Ă©tĂ© rĂ©alisĂ©e de façon systĂ©matique. Huit de nos malades ont Ă©tĂ© abordĂ©s par voie cervicale permettant une exĂ©rĂšse complĂšte du sac. Le recul moyen Ă©tait de 38 mois sans rĂ©cidive. Toute laryngocĂšle dĂ©couverte, doit ĂȘtre traitĂ©e afin d’éviter les complications essentiellement locales pouvant mettre en jeu le pronostic vital. Les modalitĂ©s thĂ©rapeutiques dĂ©pendent du type de la laryngocĂšle.Mots-clĂ©s : laryngocĂšle, nasofibroscopie laryngĂ©e, traitement endoscopique, thyrotomie.A laryngocele is a rare affection which consists in an abnormal dilatation of the laryngeal saccule. The diagnosis is suspected after clinical exam. The management of this pathology remains a subject of debating. We report a retrospective review including nine patients with laryngocele treated over a 14 years-period. Six patients had external laryngoceles; two had combined laryngocele; another one had an internal laryngocele. Preoperative diagnosis of each patient was made on flexible nasolaryngoscopy following routine otorhinolaryngologic exam. CT scan was systematically done. mrI was realized in case of a diagnostic doubt. eight of our patients were treated via external approach. no recurrences were encountered during the following-up. Laryngoceles must be treated to provide different complications. Some of these complications can cause death. The modalities of the treatment depend on the type of laryngocele.Keywords : laryngocele, nasolaryngoscopy, endoscopic treatment, thyrotomy

    MPM Job-shop under Availability Constraints

    Get PDF
    A large part of scheduling literature assumes that machines are available all the time. In this paper, the MPM Job-shop scheduling problem, where the machine maintenance has to be performed within certain time intervals inducing machine unavailability, is studied. Two approaches to solve the problem are proposed. The first is a two-phase approach where the assignment and the sequencing are solved separately. The second is an integrated approach based on the exact resolution of the 2-job problem using the geometric approach

    Objectifs : PrĂ©ciser les principes du traitement chirurgical et les particularitĂ©s des poches de rĂ©traction tympaniques (PDR) chez l\'enfant. MatĂ©riel et mĂ©thodes : Nous rapportons une Ă©tude rĂ©trospective Ă  propos de 37 PDR (28 enfants) opĂ©rĂ©s entre 1995 et 2006. Tous les patients avaient bĂ©nĂ©ficiĂ© d\'un examen clinique et un bilan audiomĂ©trique. Le traitement consistait en un renforcement tympanique par un greffon cartilagineux Ă©ventuellement associĂ© Ă  une attico-mastoĂŻdectomie. Les rĂ©sultats anatomiques et fonctionnels post opĂ©ratoires ont Ă©tĂ© Ă©valuĂ©s avec un recul moyen de 29 mois. RĂ©sultats : L\'Ăąge moyen des patients Ă©tait de 10,5 ans et le sex-ratio de 1,33. Sept enfants avaient des antĂ©cĂ©dents d\'otite sĂ©romuqueuse bilatĂ©rale, avec pose d\'ATT. L\'hypoacousie Ă©tait le signe fonctionnel le plus frĂ©quent (67,8%). Les PDR Ă©taient classĂ©es stade III, II et I (Charachon) respectivement dans 56,8%, 29,7% et 13,5% des cas. L\'audiomĂ©trie trouvait une surditĂ© de transmission moyenne Ă  25 ± 15 dB. Une chirurgie de renforcement a Ă©tĂ© pratiquĂ©e dans tous les cas, associĂ©e Ă  une mastoĂŻdectomie chez 12 patients. Aucune rĂ©cidive de rĂ©traction n\'a Ă©tĂ© notĂ©e en post opĂ©ratoire. Par ailleurs, l\'analyse des rĂ©sultats fonctionnels a montrĂ© un gain auditif moyen de 10 dB et un Rinne rĂ©siduel < 15 dB dans 75,6% des cas. Conclusion : La chirurgie de renforcement tympanique par du cartilage, prend une place importante dans la prise en charge des PDR de l\'enfant et donne d\'excellents rĂ©sultats anatomiques et fonctionnels.Objective: To precise the bases of surgical treatment and the particularities of tympanic retraction pockets (RP) in children. Materials and methods: We report a retrospective study about 37 RP (28 children) operated between 1995 and 2006. All patients had otological examination, nasal endoscopy and audiometric explorations. Treatment consists in reinforcement of the tympanic membrane with cartilage graft in all cases. After treatment, anatomical and functional results were evaluated with a mean follow-up of 29 months. Results: Mean-age was 10,5 years and sex-ratio 1,33. Seven children had bilateral seromucous otitis with ventilation tube insertion. Hearing-loss was the most frequent sign (67,8%). RP were classified (Charachon) stage III, II and I in 56,8%, 29,7% et 13,5%, respectively. Audiometery showed an average air conduction threshold of 25± 10 dB. Reinforcement tympanoplasty was performed in all cases, associated with canal wall-up mastoidectomy in 12 ears. No recurrence of retraction of the graft has been noted after treatment. Furthermore, analysis of functional results showed an average air conduction gain of 10 dB and air conduction gap < 15 dB in 75,6 % of cases. Conclusion: Reinforcement tympanoplasty with cartilage, takes a large place in the management of RP in children and achieves good anatomical and functional results.
