Cancer Biology & Medicine 2016年第3期13卷 384-388页

作者： Manel Dridi Nesrine Mejri Soumaya Labidi Mehdi Afrit Houda El benna khaoula ben Miled Hamouda Boussen Medical Oncology Department Abderrahmen Mami Hospital Radiology Department Abderrahmen Mami Hospital

Objective: Implantable port thrombosis(IPT) in cancer patients is a relatively rare but severe complication. Several factors are reportedly associated with the occurrence of thrombosis. We aimed to describe the prevalence and the anatomoclinical features of IPT observed in cancer patients who were treated in a medical oncology department in ***: A total of 600 cancer patients who had port implantation from January 2013 to December 2015 were retrospectively identified. Cases with symptomatic/incidental IPT(radiologically confirmed) were further identified. Epidemiological and anatomoclinical features were collected from patient records and the department ***: We observed that 33 of the 600 patients had IPT; thus, the prevalence was 5.5%. The median age was 57 years, and the gender ratio was 0.43. Overweight or obesity was observed in 73% of the patients. IPT occurred mainly in patients with breast(36.4%) and colorectal(33.3%) cancers, which were mostly nonmetastatic(79%). At least one identified classical thromboembolic risk factor was found in 13 patients(smoking in 9, tamoxifen in 2). IPT was symptomatic in 93% of the cases, occurring within an average time of 56 days. Implantable ports were removed because of infection in 2 cases and nonfunctionality in 3 cases. IPT treatment was based on low-molecular-weight heparins(94%) and antivitamin K(6%) for an average of 130 days. Four patients had post-therapy complications: one thrombosis recurrence and three ***: IPT cases in the 600 patients were observed to occur in obese nonmetastatic cancer patients within the first 3 months after IP implantation.

Primary Lymphoma of the Larynx: A Case Report and Literature Review

Open Journal of Clinical Diagnostics 2015年第2期5卷 81-85页

Background: Primary non-hodgkin lymphoma of the larynx is a rare entity accounting for 1% of laryngeal tumors. Fewer than 100 cases have been reported in the literature. Case presentation: A 52-year-old man, presented with a two-month history of dysphonia. Nasofibroscopy showed left submucosal bulging of the laryngeal supraglottic floor. Cervical computed tomography showed extensive left supraglottic mass, with partial lysis of the thyroid cartilage. Direct laryngoscopy showed left submucosal bulging of the supraglottic floor. Transmucosal biopsies were performed. Histological study concluded to the presence of a diffuse large-cell B lymphoma. The patient was treated with chemotherapy followed by external radiotherapy. Evolution was favourable. Conclusion: Although primary laryngeal non-hodgkin lymphoma is rare, it should be considered in the differential diagnosis of a mass in the neck region, especially in the supraglottic area. Direct laryngoscopy with biopsy makes the diagnosis. Treatment and prognosis depend on the stage and the grade of the lymphoma.

Interstitial Lung Diseases Associated with Connective Tissue Pathologies: Radiologic Features

引用

Open Journal of Respiratory Diseases 2019年第4期9卷 112-122页

作者： Houda Gharsalli Monia Attia Sawssen Hantous-Zannad Imen Sahnoun Sonia Maalej Leila Douik El Gharbi Henda Neji khaoula ben Miled-Mrad Department of Pulmonology Abderrahmane Mami Hospital Ariana Tunisia University of Tunis El Manar Tunis Tunisia Department of Radiology Abderrahmane Mami Hospital Ariana Tunisia

Introduction: The high resolution computed tomography (HRCT) is an important part in the diagnostic approach of interstitial lung disease (ILD) associated with connective tissue diseases (CTD) by providing detailed information on the elementary lesion and the radiological pattern of ILD. Aim: to point out the role of HRCT in the diagnosis of ILD associated with CTD (ILD-CTD). Methods: A Retrospective descriptive study was conducted between 2008 and 2017. Data of 24 patients presenting ILD-CTD were collected. A review of HRCT was performed by a radiologist without knowledge of the CTD. Results: Predominant elementary lesion of ILD associated with dermatomyositis (9 cases) was ground glass opacity (n = 9) followed by consolidation (n = 6). Non Specific Interstitial Pneumonia (NSIP) was the most reported pattern (5 cases). Ground glass opacity was also the predominant elementary lesion for the 2 cases of scleroderma and in Sjögren’s syndrome (4 cases/5). NSIP was the predominant radiological presentation in these two CTD. Lymphoid interstitial pneumonia revealed Sjögren’s syndrome in one case. In rheumatoid arthritis (6 cases), the elementary HRCT lesions were irregular interlobular septal thickening (n = 4) and honeycombing (n = 4) consistent with Usual Interstitial Pneumonia (UIP) in 2 cases. Similarly UIP has been described for the 2 patients with lupus and mixed connective tissue disease. Conclusion: HRCT plays an important role in the management of ILD-CTD. Description of the HRCT elementary lesions and the radiological pattern of ILD can be helpful for CTD’s diagnosis.

Preliminary Palynostratigraphic Data on the Middle Albian-Lower Cenomanian of the Tarfaya Basin, Southwest Morocco

引用

Open Journal of Geology 2024年第4期14卷 548-568页

作者： khaoula Chafai Touria Hssaida Wafaa Maatouf Mohamed Z. Yousfi Sara Chakir Soukaina Jaydawi Hanane Khaffou Department of Geology Faculty of Sciences Ben M&#8217Sik University Hassan II Casablanca Morocco Department of Petroleum Laboratory Office National des Hydrocarbures et des Mines Rabat Morocco Department of Geology Faculty of Sciences Dhar El Mahraz Sidi Mohamed Ben Abdellah University Fes Morocco Department of Geology Faculty of Sciences Mohammed V University Rabat Morocco

The Tarfaya-Laayoune-Boujdour basin is of great interest to oil exploration;on this aspect, there has been exploration by the Moroccan National Office of Hydrocarbons and Mining, which has shown indices of oil and/or gas recorded in most wells drilled in the Moroccan Atlantic margin. FD-1 well, object of this study, is one of these wells located in the offshore Tarfaya-Laayoune-Boujdour basin. A palynological examination of the processed samples revealed the existence of organic palynomorphs, well conserved and rich in dinoflagellate cysts. The latter are composed of worldwide marker taxa of high stratigraphic resolutions. Thus, the middle upper Albian (3408 - 3408.5 m) is determined by the presence of Cribroperidinium tensiftense, Tehamadinium coummia, Spiniferella cornuta, Chichaouadinium vestitum, Dinopterygium alatum and Litosphaeridium arundum. The upper Albian (3406.5 - 3408 m) is characterized by the FOs of marker taxa: Cyclonephelium chabaca, Cribroperidinium auctificum and Chichaouadinium vestitum. Lastly, the upper Albian-lower Cenomanian transition is defined between 3404 m and 3406.50 m, as suggested by the FOs of Chichaouadinium boydii, Dinopterygium tuberculatum, Sepispinula ancorifera, Litosphaeridium conispinum, Prolixosphaeridium conulum and Xenascus ceratioides.
