Aim: Determine the frequency and respective proportion of the various etiological forms of arthritis in Lomé (Togo). Patients and Methods: Transversal study carried out over 15 years on files of arthritis infected patients and submitted to rheumatologic consultation. Results: 1081 out of 13,517 patients examined (8%) were suffering from arthritis. Those 1081 patients (456 women, 42.2% and 625 men, 57.8%) were in average 38 years old and enjoyed an average duration of evolution of three years. The chronic inflammatory rheumatisms (CIR) (602 cases, 56.9%), the metabolic arthropathies (233 cases, 22%) and the infections (198 cases, 16.6%), were the main etiologies that were observed. The average age of 198 patients with infectious arthritis was 36 years and the average duration of 9 months. Infectious arthritis was preferably located at the knee (34.3%), and was essentially caused by a banal germ (157 patients;79.3%) and associated with hIV in 25 patients (15.9%). The remaining 233 patients (9 women, and 224 men) suffering from metabolic arthritis were in average 52 years old and enjoyed an average duration of evolution of five years. The chronic inflammatory rheumatisms were mainly represented by spondyloarthropathies (90 cases, 14.9%) and the arthritis rheumatoid (64 cases, 10.6%). 399 out of 602 cases of the CIR were not classified while 52 cases were associated with hIV. The connective tissue diseases were dominated by the polymyositis (9 cases, 18.7%). Conclusion: The chronic inflammatory rheumatisms were the first causal form of arthritis in rheumatologic consultation in Lomé.

Objectives: To determine the epidemiological, clinical and paraclinical profile of bone metastases cancer. Patients and Methods: It was a retrospective study performed on a series of cases, admitted in Rheumatology department of the University Teaching hospital of Lomé, Togo from October 1989 to December 2008. The diagnosis of bone metastasis was made because of the existence of inflammatory bone pain, or pathological fracture, or bone swelling and a bone condensing or mixed or osteolytic radiological image. The anatomopathological evidence was made after biopsy of the bone lesion or primary cancer. 2018 patients were hospitalized in rheumatology, and among them 77 had documented bone metastasis. Results: There were 53 men (68.8%) and 24 women (31.2%) with a sex ratio of 2.2. The mean age was 56.6 ± 12.6 years, ranging from 21 to 82 years. The primary cancer most frequently found was that of the prostate, representing 57.1% of bone metastasis and breast in 15.6%. The main manifestations of patients with bone metastases were inflammatory bone pain (76.6%) and alteration of general condition (75.3%). The spine was the main area of pain (64.9%). The metastasis was bone condensing in 48.1% of cases, osteolytic in 40.3% and mixed in 11.6%. The average survival was 22 months. Conclusion: The clinical and radiological presentation remains classic. Cancer of the prostate and breast are the main neoplasia responsible for bone metastasis in our series. The diagnosis of the primary tumor is often made at the stage of metastasis in black Africa.

Objectives: To determine the frequency, the clinical and radiological features of lumbar spondylolisthesis in a rheumatological practice in Lomé. Patients and methods: This was a cross-sectional study conducted in the rheumatology department of the Sylvanus Olympio Teaching hospital in Lomé between January 1997 and December 2019. Medical records of patients with symptomatic spondylolisthesis with radiographic confirmation were reviewed. The Meyerding classification system was used for grading. Results: Of the 350 patients contacted, 118 consented to participate in the study, making a response rate of 33.71%. Of the 118, 104 (88.1%) were females. 109 (92.4%) presented with radicular pain and 9 (7.6%) presented low back pain. The mean age of the patients was 54.24 ± 11.19 years. The average duration of the pain was 4.56 ± 1.32 years. The spondylolisthesis level most involved was the L4 - L5 (92/118), followed by L5 - S1 (23/118). 106 (89.8%) patients had anterolisthesis only, seven (5.9%) combination anterolisthesis and retrolisthesis. The spondylolisthesis was associated with spondylosis in 110 (93.2%) patients. Spondylosis was found at level L4 - L5 in 38.98% patients, followed by L5 - S1 (24.58%), L3 - L4 (18.64%). Grade I slip was found in 108 (91.53%) patients and Grade II slips 10 (8.47%). Isthmic lysis was found in 40 (33.9%) patients and it was located at L4 in 30 (75.0%). Conclusion: Lumbar spondylolisthesis appears to be expected in Lomé patients with nonspecific back pain and mainly affects females.

The BN-600 full mixed oxide fueled core is modeled using MCNPX code. A three dimensional model typical of the core is prepared which includes 6 radial zones, low enrichment zone, medium enrichment zone and high enrichment zone, two zones of steel shielding assemblies, and a radial blanket in addition to shim and scram rods. The twelve axial zones are also modeled. The model calculates core parameters such as reactor multiplication factor, power distribution through reactor core, and control rod worth. An estimation of isotope transmutation through various reactor zones and analysis of internal breeding zone were presented. The results are compared with previously published results which indicated good agreement. Typical results of the present model for reactor multiplication factor are 1.00832 compared with transport model (1.00664) and diffusion model (1.00131). The high enrichment zone dominates power production. The results also estimate the isotope variation due to burnup in the MOX core.

Objective: To study the effect of cerebral ischemic vascular insult on the localization of language areas as regard to automatic speech, initiation, and mutism. Materials and Methods: Seventy ischemic stroke patients were selected within the first 48 h of the onset of stroke with left hemispheric stroke with aphasia. Inclusion criteria: any age above seven years, both sexes, first ever clinical stroke, admitted within the first 2 days of stroke insult. Patients underwent careful history taking, neurological examination, routine laboratory investigations, echo cardiography, and carotid duplex and language assessments. Results: Automatic speech disorders were mainly seen along left insular, left supramarginal and left frontal inferior orbital lesions. Initiation difficulty is seen mainly along as left insular, left temporal superior and left periventricular lesions. Mutism is seen along left external capsule, left internal capsule, left pallidum, left frontal inferior orbital and left inferior trigone lesions. Conclusions: Deep periventricular white matter and insular area in the dominant hemisphere play an important role in many language tasks. Thus aphasia is not a mere cortical function.

对浙江省内花岗质岩石样品薄片在偏光显微镜下鉴定,试图建立矿物学与微构造之间的联系,确定裂隙分布矿物学控制因素,并调查微裂隙与交代变质蚀变之间的关系.薄片显示花岗质岩石主要由斜长石、钾长石、石英和云母组成.其中长石和云母解理发育,在结构上更易于变形,而石英则表现为均质特征,其中的裂隙比其他矿物(长石、云母)中更发育.这些解理和裂隙接纳流体进入并造成交代变质.在此过程中,黑云母被白云母交代而形成石英并释放出钾,这些钾进而交代斜长石而形成钾长石.值得关注的是,一些矿物颗粒边界显现出很少的变形,如钾长石-斜长石边界和石英-石英边界呈现较低程度的颗粒间碎裂,并变得可能比以前更坚硬,这是因为重结晶作用和交代作用胶结了以前的碎裂结构.最后,变形作用影响到整个岩石,为流体通过岩石打开通道,进一步的微裂隙对大规模钾交代变质作用的发生至关重要.研究区内花岗岩的矿物学及裂隙特征表明,交代作用可以作为可靠的构造标志,用以恢复浙江花岗岩现代和古裂隙的几何特征.

Objectives: To determine the epidemiological, clinical, and bacteriological characteristics of septic arthritis of the hip (SAh) among patients hospitalized in the departments of Rheumatology in Lomé. Patients and Methods: This was a multicentre, descriptive study, conducted over a 16-year period, from January 2004 to December 2020 on patients’ records at the three departments of Rheumatology in Lomé. We included in this study only patients with complete laboratory and radiological data. Patients who underwent hip replacement surgery and those with arthritis of the hip due to all inflammatory arthropathies were excluded. The diagnosis of SAh was based on clinical, radiological and bacteriological features. In the absence of bacteriological confirmation, the presumptive etiological diagnosis was based on epidemiological data, contacting with a person with tuberculosis, the presence of high-grade fever, the mode of presentation of the symptoms, the patient’s general appearance, and the result of the tuberculin skin test. The data was collected using Epi info 7.0 and statistical analysis was performed using STATA/IC 11.0. Results: Out of 3776 patients hospitalized in the three departments over the study period, 705 (18.67%) were diagnosed with septic arthritis of which 70 (9.92%) patients with SAh. The 70 patients with SAh were 44 (62.86%) females, and 26 (37.14%) males, with a sex ratio of 1.7 F/M. The mean age of the patients was 42.43 ± 19.37 years (range: 5 years and 80 years) and the mean duration of symptoms was 6.57 ± 8.85 months (range: 2 days and 48 months). The pain was inflammatory in nature in 46 (65.71%) and mechanical in nature in 24 (34.29%) patients. The onset of the disease was progressive in 50 (71.43%) patients and sudden in 20 (28.57%) patients. The locations of the pain were: groin only 25 (35.71%), greater trochanter only 15 (21.43%), groin and lower back 14 (20%
