Examination checks for sensory differences between the affected leg and the other leg.Differentiation of meralgia paraesthetica from a second lumbar root lesion remains the greatest problem in diagnosis and relies on the careful delineation of the paraesthetic area, the degree of numbness and a negative MR scan of the lumbar spine. Although the L2 area and the area supplied by the lateral cutaneous nerve correspond well laterally, the second root also contributes to the innervation of the groin and the inner aspect of the thigh. Furthermore, in L2 root lesions the analgesia is very slight because of the overlap between L2 and L3, whereas in lesions of the lateral cutaneous nerve, there is
almost full anaesthesia, with a clear-cut border.Accurate diagnosis may require an abdominal and pelvic examination to exclude problems in those areas.Electromyographic (EMG) nerve-conduction studies may be required.X-rays may be needed to exclude bone abnormalities that might put pressure on the nerve; likewise CT or MRI scans to exclude soft tissue causes such as a tumor. Treatment
Treatment varies. In most cases, the best treatment is to remove the cause of compression by modifying patient behavior, in combination with medical treatment to relieve inflammation and pain. Whatever the cause, typical treatment takes several weeks to months—depending on the degree of nerve damage. Typical treatment options include:
Active Release Technique (ART) soft tissue treatment
Wearing looser clothing and suspenders rather than belts
Weight loss if obesity is present
Non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammatory pain if pain level limits motion and prevents sleep
Reducing physical activity in relation to pain level.
Monocytosis is an increase in the number of monocytes circulating in the blood. Monocytes are white blood cells that give rise to macrophages and dendritic cells in the immune system. In humans, monocytosis occurs when there is a sustained rise in monocyte counts greater than 800/mm3 to 1000/mm3.Monocytosis has sometimes been called mononucleosis, but that name is usually reserved specifically for infectious mononucleosis. Causes
Monocytosis often occurs during chronic inflammation. Diseases that produce such a chronic inflammatory state:
Infections: tuberculosis, brucellosis, listeriosis, subacute bacterial endocarditis, syphilis, and other viral infections and many protozoal and rickettsial infections (e.g. kala azar, malaria, Rocky Mountain spotted fever). Blood and immune causes: chronic neutropenia and myeloproliferative disorders. Autoimmune diseases and vasculitis: systemic lupus erythematosus, rheumatoid arthritis and inflammatory bowel disease. Malignancies: Hodgkins disease and certain leukaemias, such as chronic myelomonocytic leukaemia (CMML) and monocytic leukemia. Recovery phase of neutropenia or an acute infection. Obesity (cf. Nagareddy et al. (2014), Cell Metabolism, Vol. 19, pp 821–835)
Miscellaneous causes: sarcoidosis, lipid storage disease and ZNFX1 deficiency.During these stages of extreme inflammation, monocytosis can damage tissues because it increases the activation of the immune response and prevents the inflammation from subsiding which is seen in cases where sepsis occurs. Diagnosis
Blood Test (CBC) (Normal range of Monocytes: 1-10%) (Normal range in males: 0.2-0.8 x 103/microliter)
Blood test checking for monocytosis (Abnormal ranges: >10%) (Abnormal range in males: >0.8 x 103/microliter)

Treatment
Ceftriaxone if there is typhoid fever and levofloxacin or moxifloxacin. Gentamicin and doxycyclin if brucellosis. References
