Introduction: Superior femoral epiphysiolysis (SFE) is a most progressive but sometimes abrupt displacement of the femoral head relative to the superior femoral metaphysis through the cervicocerebral growth plate of the femur. The displacement of the femoral head is most often downward and backward. It is a typical pathology of the pubescent adolescent, most often overweight. It occurs on average at the age of 12 years in girls and 14 years in boys. Unstable forms with large displacements have a high risk of femoral head necrosis and chondrolysis. Although in situ fixation is the generally accepted treatment for minor SFE, the treatment of more severe cases remains controversial. When the extent of the displacement makes it impossible to pass a screw between the femoral neck and the femoral head, the only option is to reduce the displacement. This reduction must be gentle, progressive and limited to the minimum necessary for osteosynthesis. Objective: The aim of the work was to evaluate the results of the technique of progressive reduction of epiphyseal displacement by transtibial traction followed by percutaneous fixation of the femoral head by screw. Patients and Method: This was a retrospective descriptive study over a 10-years period from January 1, 2013 to December 31, 2022. It focused on the surgical treatment of unstable upper femoral epiphysiolysis with large displacement in the orthopaedic trauma department of the University Hospital of kati. All patients operated on in our department for large displacement SFE were included in this study. Cases of secondary large displacement upper femoral epiphysiolysis and patients who had already undergone surgery on the proximal femur were excluded. Continuous progressive traction on the Boppe splint through a pin under the anterior tibial tuberosity was performed for 15 days in all patients. The hip was flexed to 45° and the knee to 35°. Fixation was performed with one or two screws. No contralateral preventive fixati

The use of textured surfaces in lubrication to improve the tribological characteristics has been widely studied. The understanding of the textured surface geometric parameters influences on these tribological characteristics could help to improve their applications in industry. In this paper, we purpose to analyze the influence of the micro-texture depth on the friction coefficient experimentally. The experiment is conducted using different copper alloy samples have been the first laser textured with different micro-hole depth (40.83 μm and 46.36 μm). A 3D electronic Olympus microscope is used to visualize the shapes of the holes and find the depths. Then, the friction test has been conducted using these samples with the same velocity. The time variation of the friction coefficient is plotted and analyzed. The analysis of time variation of the friction coefficient shows a reduction of friction coefficient with the increase of the micro-hole depth has been observed. In some cases, this reduction is significant.

Bemisia tabaci-transmitted geminiviruses are one of the major threats on cassava and vegetable crops in Africa. However, to date, few studies are available on the diversity orB. tabaci and their associated endosymbionts in Africa. More than 28 species have been described in the complex ofB. tabaci cryptic species; among them, 2 are invasive pests worldwide： MED and MEAM1. In order to assess the species diversity orB. tabaci in vegetable crops in Senegal, several samplings in different localities, hosts and seasons were collected and analyzed with nuclear （microsatellite） and mitochondrial （COI） markers. The bacterial endosymbiont community was also studied for each sample. Two species were detected： MED Q1 and MEAM1 B. Patterns of MED Q1 （dominance on most of the samples and sites, highest nuclear and mitochondrial diversity and broader secondary endosymbiont community： Hamiltonella, Cardinium, Wolbachia and Rickettsia）, point toward a predominant resident begomovirus vector group for MED Q 1 on market gardening crops. Furthermore, the lower prevalence of the second species MEAM1 B, its lower nuclear and mitochondrial diversity and a narrower secondary endosymbiont community （Hamiltonella/Rickettsia）, indicate that this genetic group is exotic and results from a recent invasion in this area.

引用

World Journal of Cardiovascular Diseases 2017年第12期7卷 435-441页

作者： traore Fatoumata Abidjan Heart Institute AbidjanCote d’Ivoire

Background: The diagnosis of deep vein thrombosis (DVT) requires an etiological research of HIV infection. The objective was to identify the characteristics of patients with DVT of limbs without other risk factors in our context. Methods: We performed a comparative retrospective study from January 2005 to December 2012. We identified 162 cases of patients hospitalized in Medicine Department of Institute of Cardiology of Abidjan with 124 HIV-negative and 38 HIV positive patients. Results: DVT is more common in HIV positive young patients (57.8 ± 15.6 years vs 39.3 ± 10.6 years, p = 0.0001). The traditional risk factors were found in HIV negative patients. HIV positive patients had no predisposing factor for thrombosis. The ankle-femoral popliteal location (29% vs 73.7% p = 0.05) was most frequent in HIV positive patients. There was no significant difference in anticoagulant therapy: UFH (60.5% vs 52.6%;p > 0.05), LMWH (20.2% vs 7.9%;p > 0.05), AVk relay (99.2% vs 100%;p > 0.05) and general measures (elevation MI). (70.2% vs 65.8%;p > 0.05). None of the patients in both groups had worn stockings in hospitalization. The stockings were prescribed on discharge (70% vs 64.7%;p > 0.05). Conclusion: DVT may be the mode of revelation of HIV infection. The etiological research with HIV infection should be systematic in?young patients suffering from DVT in the absence of risk factors of thrombosis.

The number of HIV-infected patients in the world is estimated at 34 million, including 30.1 million adults with 2.7 million new infections and 1.8 million deaths from HIV according to the 2011 UN AIDS report [1]. The prevalence of HIV infection in the general population of Mali is estimated at 1.1% according to DHSM-V [2]. Cardiovascular manifestations are increasingly encountered during our consultations with patients living with HIV. Thus we initiated this work with the aim of studying the cardiovascular lesions during the HIV-AIDS in the department of internal medicine of the point G. Methods: This retrospective descriptive study was conducted in the Internal Medicine department of the University Hospital Center (CHU) of the Point G from January 2008 to December 2012. Having included all HIV + patients hospitalized in the service with cardiovascular manifestations and who had performed a chest X-ray, cardiac and vascular ultrasound, electrocardiogram and/or cerebral computed tomography. Results: At the end of this work, 20 patients with cardiovascular lesions were identified in 273 hospitalized patients during the study period, i.e. a frequency of 7.3%. The 40 to 50 age group accounted for 45.0% with an average age of 42.4 ± 8.73 years. The most common cardiovascular risk factors were hypertension and active smoking with 31.58% each. Pericarditis accounted for 32% of cases, followed by cardiomyopathies with 23%. Conclusion: In our study, cardiovascular lesions are common in PHAs and etiologies are dominated by pericarditis.

Despite the efforts made by the Malian government with technical and financial partners in the fight against HIV and AIDS, there are no data on the evolution of people with HIV in medical consultation in antiretroviral treatment sites. The objective of this work is to fill this gap by generating factual data describing the evolution of the number of people with HIV in medical consultation in Mali. To achieve this goal, we conducted a cross-sectional study using data from the Coordination Unit of the Sectoral Committee for AIDS Control of the Ministry of Health and Public Hygiene. Sampling was comprehensive including all people living with HIV. The data collected concerned those of the years 1999 to 2014 by the ESOPE software and analyzed with Stata version 12. A Total of 39,619 people were enrolled in the study. And 26,212 people living with HIV in the 17 ESOPE sites of Mali were female. Patients aged 25-34 and 35-44 years were strongly represented in consultation in the years 2007 and 2011, and those aged 15-24 were the least frequent. HIV1 was the most dominant with 97%. The majority of patients presented for initial consultation were clinical stages 2 and 3 in all years. Cases of lost sites seen in the more common in hospitals are 62.79% at the Hospital of Mopti and 57% at the University Hospital of Point G. The number of cases of people living with HIV in medical consultation has progressively augmented from 1999-2007. Then it dropped from 2008-2010. After this number has increased by 2011, it dropped again in 2012-2014. This study made it possible to note the evolution of the patients in medical consultation in ESOPE antiretroviral treatment sites according to the years and events (safe, subsidized by activities by the global fund). The activities of sensitization and communications, case research should be strengthened by involving the community.

Population development of key groups of anaerobic and aerobic bacteria involved in municipal refuse decomposition under laboratory landfill bioreactors with and without leachate recycle and inoculation was measured since modeling municipal refuse was landfilled in bioreactors for about 210 days. Hydrolytic fermentative bacteria (HFB), hydrogen-producing acetogenic bacteria (HPAB), methane-producing bacteria (MPB), sulfate-reducing bacteria (SRB), anaerobic and aerobic cellulolytic bacteria and denitrabacteria were enumerated by the most probable number technique. The results showed that the dominant microorganism groups were the methanogenic bacteria including hydrolytic fermentative, hydrogen-producing acetogenic and methane-producing bacteria. They were present in fresh refuse but at low values and positively affected by leachate recycle and refuse inoculation. The amounts of HFB or HPAB in digesters D4 and D5 operated with inoculation and leachate recycle reached their maximum values of 1010 - 1012 cells/g dry refuse for HFB or 105 - 106 cells/g dry refuse for HPAB on day 60, in digester D3 operated with leachate recycle on day 120 for HFB (109 cells/g dry refuse) or on day 90 for HPAB (105 cells/g dry refuse), and in digesters D1 and D2 on day 210 for HFB (109 cells/g dry refuse) or on day 90 for HPAB (104 - 106 cells/g dry refuse). The population of methane-producing bacteria in digesters D4 and D5 sharply increased on days 60 and 90 respectively, however in digesters D1, D2 and D3 on day 120. Leachate recycle and inoculation changed the cellulolytic microorganisms composition of refuse ecosystem, the higher amounts of anaerobic cellulolytic bacteria were measured in digesters D4 and D5 (107 cells/g dry refuse), followed by digesters D3 (106 cells/g dry refuse), D2 or D1 (104 cells/g dry refuse). However, the amounts of aerobic cellulolytic bacteria were much lower than that of anaerobic cellulolytic bacteria. And it was higher in digesters D3 than those in dig

作者： Bangaly traore Leopold Lamah Surgical Oncology Unit National Hospital of Donka Conakry University Hospital Conakry Guinea Department of Orthopedics and Traumatology National Hospital of Donka Conakry University Hospital Conakry Guinea

Aim: The main aim of this study was to evaluate outcomes after surgical treatment of skin cancer. Methods: This retrospective cohort study concerned 46 patients who presented 43 skin cancers lesions surgically treated at surgical oncology unit, Conakry University Hospital. There were 29 (61.7%) squamous cell carcinoma, 12 (25.5%) melanoma, 4 (8.5%) sarcomas and 1 (2.1%) porocarcinoma. Surgical indications and prognosis factors were analyzed. Results: Surgical treatment included simple excision in 2 cases (3.8%), wide excision in 38 cases (71.7%) and amputation/disarticulation in 13 cases (24.5%). Inguinal lymph node dissection was performed in 16 patients (34.3%). Postoperative complications were wound suppuration (5 cases), lower limb lymphedema (4 cases), seroma (2 cases) and skin flap necrosis (1 case). Surgical margins were free in 28 (60.9%) patients, infiltrated in 3 patients (6.5%) and unspecified in 15 patients (32.6%). The median follow-up after surgery was 29 months. During the follow-up, 13 patients (28.3%) had a relapse. The relapse was influenced by surgical margins (p = 0.012) and iterative resection (p = 0.04). Overall survival was 65.2%. Factors related to survival in univariate analysis were: iterative resection (p = 0.008), fungated tumor (p = 0.037), the status of surgical margins (p = 0.002) and the occurrence of relapse (p = 0.0000). In multivariate analysis, the status of surgical margins was the only independent prognostic factor. Conclusion: The prognosis after surgical treatment of cutaneous cancers depends on the resection margins.

Introduction: A fracture is a solution in the continuity of a bone. Pelvic limb fractures may involve one or more of the bones. They constitute a real public health problem, which requires the identification of the factors inherent to this phenomenon for better prevention, but also for quality management of fractures and sequelae. Objectives: Were to describe the epidemiological, clinical and therapeutic profile of pelvic limb fractures in Timbuktu Hospital. Patients and Method: We conducted a prospective, descriptive study in the Surgery Department of Timbuktu Hospital, covering a period of one year from January 1 to December 31, 2017. We collected 39 patients who presented with fractures of the pelvic limbs, who were hospitalized and monitored throughout our study. Results: We obtained a hospital frequency of 2.86% limb fractures. Among the 39 patients included in our study, the male sex was predominant in 69.2% of cases, the average age of our patients was 20.5 years. Pupils and students were in the majority in 48.7% of cases. Road traffic accidents were the most common cause of fracture with 59.0% of cases. The tibia was the most affected segment in 38.5% of cases. Surgical treatment was predominant in 64.0% of cases. We obtained very good results in 94.87% of cases. Conclusion: Limb fractures remain frequent due to road traffic accidents. Osteosynthesis treatment provides a good result with fewer complications.
