Internal Fixation of Gunshot Induced Fractures in Civilians: Anatomic and Functional Results of a Standard Protocol at an Urban Trauma Center

引用

Open Journal of Orthopedics 2016年第3期6卷 63-70页

作者： Anani Abalo Atsi Walla Gamal Ayouba Yaovi yannick Dellanh Kosivi Fortey Assang Dossim Department of Orthopaedics Tokoin Teaching Hospital Lomé Togo

Introduction: Despite extensive experience with civilian gunshot fractures or wounds, no consensus exists on a standard protocol to manage these injuries. Many authors recommended immediate debridement, but the optimal timing of internal fixation and the use of antibiotic have not been determined. The purpose of this paper is to present and discuss our experience. Material and methods: In January 2007, a treatment protocol was put in place for the evaluation and management of fractured extremities resulting from civilian gunshot wounds. Sixty-three patients with 64 fractures had been managed by this protocol for gunshot fractures between January 2005 and January 2012. There were 56 male and seven female. Their mean age was 33.1 years (range: 17 - 61 years). Thirteen patients (20.6%) were able to provide a description of the weapon. Only 15 patients had entry and exit wounds. The mean follow-up period was 27 (range, 20 - 58) months. The main factors assessed were the surgical site infection, the fracture union and the functional status. Results: Out of the 63 patients, 14 patients developed a wound infection (five superficial and seven deep infections). Wound infection was significantly associated with associated injuries (p = 0.0388), fractures sites requiring fixation (p = 0.024), the fracture pattern (p = 0.0412), operative modalities (p = 0.0400). There were nine cases (14.1%) of fracture non-union. The mean time to union was 15 weeks (range: 5 - 32 weeks). Five patients developed chronics osteomyelitis. The average SMFA score for all of the patients was 23.8 (range: 0 - 56.3). The mean dysfunctional and bother indexes were 18.3 (range: 0 - 52.7) and 22.6 (range: 0 - 66.1), respectively. The SMFA total score and dysfunction index had a significant correlation based on presence or absence of associated injuries (p < 0.0001). But bother index did not show the same correlation (p = 0.452). The average length of hospital stay was 11.3 days (range: 3 - 64). Conclusion

Isolation and Characterization of Enterococci Bacteriocinic Strains from Tunisian Fish Viscera

Food and Nutrition Sciences 2013年第6期4卷 701-708页

A collection of lactic acid bacteria isolates from fish viscera was studied and investigated regarding to their functional properties and safety aspects. From these, three isolates GM1, GM2 and GM3 were identified as Enterococcus feacium species using molecular methods. Partial Amplified rDNA Restriction Analysis (partial ARDRA) with restriction enzyme HaeIII separated these isolates into distinctive group which suggest genotypic variability within enterococci strains isolated from fish viscera. The three strains GM1, GM2 and GM3 exhibited antimicrobial activity. Indeed strains have been shown to produce bacteriocins with inhibitory effect against food spoilage bacteria and pathogenic fish including Carnobacterium maltaromaticum. The molecular mass of bacteriocin, as calculated by tricine-SDS-PAGE, was found to be 4.5 kDa. All isolates were tested positive upon PCR amplification of enterocin A structural gene. Investigations of antibiotic resistance show that the isolates were mostly sensitive to several antibiotics (ampicillin, penicillin, tetracycline, gentamycine) and resistance to rifampicin. All isolates grow in esculin azide agar as a selective medium for enumeration of probiotic enterococci. This study suggests that our strains can be employed as probiotic or to improve the safety of food products.

Ischemic <i>Cauda equina</i>Syndrome Due to Spinal Embolization as a First Manifestation of an Infrarenal Abdominal Aortic Aneurysm

引用

World Journal of Cardiovascular Surgery 2015年第6期5卷 58-62页

作者： Youssef Zrihni Tiia Kukkonen Fabien Thaveau Elie Girsowicz yannick Georg Nabil Chakfe Department of Vascular Surgery and Kidney Transplantation University Hospital of Strasbourg Strasbourg France Department of Vascular Surgery Helsinki University Central Hospital Helsinki Finland

Spinal cord ischemia is an uncommon complication of an abdominal aortic aneurysm (AAA). We report the case of a 59-year-old man admitted for an acute ischemic Cauda equina syndrome secondary to a spinal cord embolization from an unknown partially thrombosed aortic aneurysm. The patient being at risk of further embolization, we achieved an emergency EVAR. The vascular post-operative course was uneventful. Neurologically, a post operative lumbar medullar MRI confirmed an ischemic Cauda equina syndrome and six months after the surgery, the patient still had a motor and sensory deficit in both lower limbs.

Microstructural, Chemical and Mineralogical Analyses for Understanding the Geotechnical Properties of Clayey Soils

引用

Journal of Minerals and Materials Characterization and Engineering 2016年第6期4卷 305-319页

This paper presents a study research in the laboratory of three clayey soils from the depression of the Lama, a tropical climate area where disorders appear on construction and roads. Samples were tested to establish the relationship between their mineralogy and their geotechnical properties. On the three clayey soils, analyses were performed to characterize the macroscopic behavior (physical tests, free swelling test and compressibility tests) and the microstructural, chemical and mineralogical characterizations by thermal analysis, chemical analysis, X-Ray diffraction, Scanning Electron Microscopy observations complementary X-ray EDS analyses. At first glance, the results of physical and compressibility tests appear not to be consistent with the free swelling test results. Indeed, these results highlighted differences in the behaviors of the samples because the swelling potential revealed by the results of physical and compressibility test does not follow the same trend as the one given by the free swelling test result. The main clay minerals in the studied clayey soils varied from fibrous clays (palygorskite) to best-known clays such as smectite and kaolinite. Microstructural, chemical and mineralogical analyses allowed to understand and explain the different trends obtained by the different types of geotechnical characterization tests of studied clayey soils.
