Objective: To determine the prevalence and factors associated with neuropathic pain in patients with non-specific low back pain. Methods: This was a cross-sectional study conducted from May to July 2016 in the Rheumatology, Neurology and Neurosurgery departments of Lome. The DN4 questionnaire was used for the diagnosis of neuropathic pain in the 200 patients with low back pain included in this study. Results: Of the 200 patients (147 women and 53 men) included in the study, neuropathic pain European Scientific Journal August 2017 edition Vol.13, No.24 ISSN: 1857 -7881 (Print) e -ISSN 1857 268 was present in 92 (46%). The average age of the 92 patients (67 women vs 25 men, p = 0.04) was 55.5 ± 12.4 years (women 55.2 ± 12.8 vs. men 54.6 ± 11.4, p = 0.5). The characteristics of neuropathic pain mainly found were: burning sensation (n = 67, 72.8%); electrical discharges (n = 64, 69.6%); tingling (n = 90; 97.8%); tickling (n = 57; 62%); numbness (n = 89; 96.7%); hypoesthesia (n = 52; 56.5%). Factors significantly associated with the presence of neuropathic pain in LBP were age (p = 0.005), duration of LBP (p = 0.04), high blood pressure (p = 0.001), radicular pain (p = 0.00002) and the past history of the LBP (0.000000). Conclusion: Neuropathic pain is common in patients with LBP at Lome. The duration of LBP, past history of LBP, previous NSAID use, BMI, pain severity and radicular pain appear to be predictive of the occurrence of these neuropathic pains. Hommes 54,6± 11,4 ; p = 0.5). Les items de la DN retrouvés étaient essentiellement : brûlures (n=67 ; 72,8%) ; décharges électriques (n=64 ; 69,6%) ; fourmillements (n=90 ; 97,8%) ; picotements (n=57 ; 62%) ; engourdissement (n=89 ; 96,7%) ; hypoesthésie (n=52 ; 56,5%). Les facteurs significativement associés à l'existence de DN au cours des LC étaient dominés par l'âge (p = 0,005), la durée d'évolution de la lombalgie (p= 0,04), l'HTA (p = 0,001), les radiculalgies (p = 0,00002) et l'antécédent de lomboradiculalgie (0,000000). Conclusion : La DN est fréquente chez des patients souffrant de LC à Lomé.L'âge, la durée d'évolution de la lombalgie, l'antécédent de lomboradiculalgie, la prise antérieure d'AINS, l'IMC, l'intensité de la douleur et les radiculalgies semblent prédictives de la survenue de ces DN.

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.

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.
