The objective of this work is to identify the difficulties in the management of these pathologies in an internal medicine department in northern Senegal by analyzing the epidemiological, clinical-biological, therapeutic and evolutionary aspects of SAID. <strong>Methods:</strong> This was a descriptive cross-sectional study carried out in the internal medicine department of the Saint-Louis University Hospital Center. Included were all the files of patients followed in outpatient and/or hospitalization for autoimmune diseases according to the criteria of the American College of Rheumatology, during the period from January 2017 to December 2020. The data were analyzed using SPSS software version 21.0. As the study was descriptive, no statistical test was performed. <strong>Results: </strong>Out of 3800 patients, 70 presented SAID, <i>i.e. </i> a hospital prevalence of 1.8%. Polyarthritis was the first reason for consultation in 97% followed by skin manifestations in 8%. The patients had positive anti-nuclear autoantibodies in 88% of cases. Rheumatoid arthritis was the predominant condition (71%) followed by systemic lupus erythematosus (SLE) (15%) and undifferentiated autoimmune diseases in 10%. Eleven percent (11%) of patients had an associated autoimmune disease. Corticosteroids were used in the treatment of these conditions in 97% of cases and methotrexate was the most prescribed immunosuppressant (54%). Thirty-two percent (32%) of patients are lost to follow-up. <strong>Conclusion:</strong> SAID are diverse and under diagnosed;they are characterized by diagnostic delay above all linked to access to specialists and sometimes to the high cost of paraclinical examinations, in particular immunology. Treatment remains based primarily on corticosteroid therapy and conventional immunosuppressants in the face of the unavailability of biotherapies.展开更多

We established a rat model of Alzheimer＇s disease by injecting β-amyloid 1-42（Aβ1-42） into the bilateral hippocampal dentate gyrus to verify which frequency may be better suited in treatment. Electroacupuncture at 2 Hz or 50 Hz was used to stimulate Baihui（DU20） and Shenshu（BL23） acupoints. The water maze test and electrophysiological studies demonstrated that spatial memory ability was apparently improved, and the ranges of long-term potentiation and long-term depression were increased in Alzheimer＇s disease rats after electroacupuncture treatment. Moreover, the effects of electroacupuncture at 50 Hz were better than that at 2 Hz. These findings suggest that high-frequency electroacupuncture may enhance hippocampal synaptic transmission and potentially improve memory disorders in Alzheimer＇s disease rats.展开更多

The LUSC includes the respiratory muscles (plus the associated connective tissues) extending to various parts of the body.

The muscles of LUSC are bounded by stiff connective tissue layers, forming compartments, and are part of the pulley system for various body locomotions. Within a compartment, the interstitial fluid, blood, lymph flows must be potent to protect the associated nerves related to LUM;the healthy state of the LUSC also provides freedom of various types of locomotion.
