Primary Prevention: Primary prevention involves preventing the condition or risk fac to r from developing. Rehabilitation: Rehabilitation is used in these Guidelines to mean physical medicine, therapeutic and rehabilitative evaluations, and procedures. Rehabilitation services are delivered under the direction of trained and licensed individuals such as physicians, occupational therapists, and physical therapists. Sometimes mental health professionals are incorporated in the treatment team, particularly for select chronic pain patients. Jurisdictions may differ on qualifications for licensure to perform rehabilitative evaluations and interventions. Secondary Prevention: Secondary prevention involves reduction in exposure or risk fac to r after the risk fac to r has already developed, but before the disease has occurred. The mechanism involves an acute, high-force deviation of the joint beyond the normal range of motion. Strain: Disruption of a myotendinous junction, usually from a high force, unaccus to med exertion(s). This term is occasionally used to describe non-specific muscle pain in the absence of knowledge of an ana to mic pathophysiological correlate. Synovitis: Synovitis refers to inflammation of a synovial membrane, although in most cases, there are not classic symp to ms and signs of inflammation. Synovial Membrane: the synovial membrane incorporates the entire femoral head, the anterior neck, and the proximal half of the posterior neck of the femur. Tendinitis: this term has been used to denote a tendon abnormality usually accompanied by pain and tenderness over the tendon or tendon origin/insertion on examination. Tendinosis: A tendon disorder that most commonly consists of an underlying, chronic degenerative tendon condition. Tendinoses are the most common types of musculoskeletal disorders, likely outpacing arthroses. Tenosynovitis: Tenosynovitis is most commonly used to refer to pain generated from the sheath and structures surrounding a tendon. The term technically refers to inflammation of a tendon sheath although in most cases there are not classic symp to ms and signs of inflammation. Classic inflammation may occur with inflamma to ry arthropathies, such as rheuma to id arthritis, or with infections. The term should be avoided for elbow disorders as tendon sheaths are absent in this body region. Tertiary Prevention: Tertiary prevention has most typically been defined as amelioration of the condition after it has already developed. For example, after a patient has osteonecrosis, precluding them from diving or other decompression activities is a method of tertiary prevention. It combines subjective ratings of pain with activities, stiffness, physical function, social function and emotional function measures. Others develop chronic tendinosis that is not infrequently attributed to physical exertion. Usually, a careful medical his to ry will reveal some contributing associated fac to r(s), but tendon injury occasionally occurs without an obvious cause. One theory is that physical exertion causes micro-injuries that accumulate with time. The tensile strength of collagen is exceeded, and the tendon tries to repair itself, but the cells produce new collagen with an abnormal structure and composition. Part of the problem may be that the new collagen fibers are less organized in to the normal parallel structure, making the tendon less able to withstand tensile stress along the direction of the tendon. This failed healing process may be one reason why some people with tendinosis do not completely clinically heal following an injury and encounter difficulties in returning to their previous level of activity. Once the tendinosis cycle starts, the tendon is believed to rarely heal back to its pre-injury state, although many patients appear to clinically resolve. Relative rest is thought to be an essential part of the acute healing process for tendinosis, to o much rest causes deconditioning of muscles and tendons. The examination of the patient with elbow symp to ms generally needs to focus on the elbow joint and include relevant neighboring structures similar to the review of systems. Findings of the medical his to ry and physical examination can alert the physician to other pathology that presents with pain or other constitutional symp to ms. Certain findings, referred to as red flags, raise suspicion of serious underlying medical conditions (see Table 4). Potentially serious disorders include infections, tumors, and systemic rheuma to logical disorders. The absence of red flags generally rules out the need for special studies, referral, or inpatient care for many patients during the first 4 weeks when spontaneous improvement or recovery is expected. Elbow disorders may be classified in to one of four working categories (note, these categories are somewhat arbitrary with significant overlap between the groups): fi Potentially serious elbow disorders: Fracture, acute dislocation, infection, or neurovascular compromise. Many musculoskeletal disorders are often categorized as mechanical disorders, although there is evidence that these disorders may be associated with degenerative changes. Non-specific disorders do not suggest necessarily internal derangement or referred pain. Disorder Medical His to ry Physical Examination Fracture His to ry of significant trauma Deformity consistent with fracture Fall on outstretched hand Reduced range(s) of motion Fall on to lateral elbow Pain with range of motion Disturbance in the triangular relationship between the olecranon and the epicondyles Significant bruising, if subacute (unusual) Dislocation His to ry of fall/trauma as above Deformity consistent with dislocation His to ry of deformity with or without Hemarthrosis spontaneous reduction Infection Pain, swelling, redness Localized heat, swelling, erythema Diabetes mellitus Purulence His to ry of immunosuppression. Many disorders of the elbow will be diagnosable with a high degree of accuracy prior to examination based upon a careful medical his to ry. Asking the patient open-ended questions, such as those that follow, allows the physician to gauge the need for further information. Discussion or more specific inquiries will usually produce the detail necessary for clinical decision-making. What are your expectations regarding your return to work and disability from this health problemfi What are your concerns about the potential for further injury to your elbow as you recoverfi What is your relationship with your co-workers and supervisor and how do they treat youfi In many cases, careful examination will reveal one or more truly objective findings, such as swelling, deformity, atrophy, reflex changes, or spasm. Examples of subjective findings include pain, tenderness to palpation, numbness and tingling, pain-limited decreased range of motion, and weakness. Examples of objective evidence signs include visible changes, swelling, deformity, redness, heat, reflex changes, spasm, palpable changes, atrophy, nonresistant passive range of motion, and imaging findings. Such evidence is perceptible to the examining physician, as opposed to the subjective sensations (symp to ms) of the patient. For most patients with elbow disorders, no truly objective physical examination evidence exists.

Viscerotropic leishmaniasis has been reported in small numbers of American military. General Considerations personnel in the Middle East, with mild systemic febrile Leishmaniasis is a zoonosis transmitted by bites of sand illnesses after L tropica infections. Cutaneous swellings appear 2 weeks to several months after Leishmaniasis is caused by about 20 species ofLeishmania; sand fy bites and can be single or multiple. Bone marrow aspiration is less sensitive but safer and diagnostic in most cases, and Giemsa-stained buff coat of peripheral blood may occasionally show organisms. Serologic tests mayfacilitate diagnosis, but none are suffciently sensitive or specifc to be used alone. Numerous antibody-based rapid diagnostic tests are available; these have shown good specificity but limitations in sensitivity outside of India. Cultures from these begin as small papules and develop in to nonulcerated dry samples may grow organisms. Serologic studies are often plaques or large encrusted ulcers with well-demarcated negative, but the leishmanin skin test is usually positive.

Diffuse cutaneous leishmaniasis India include four doses of 5 mg/kg over 4-10 days and a involves spread from a central lesion to local dissemination single dose of 15mg/kg, but efcacy appears to be lower in of nodules and a protracted course. Conventional amphotericin B deoxycholate, which ous leishmaniasis involves multiple nodular or ulcerated is much less expensive, is also highly effective but with more lesions, often with mucosal involvement. It is administered as a slow intravenous infusion of 1 mg/kg/day for 15-20 days or 0.

The margins of the lesion are relatively well demarcated, often presenting a scalloped border. They exhibit rapid growth, root resorption, perfora tion of cortical bone, and a higher recurrence rate. Hemosiderin laden macrophages and extravasated erythrocytes are usually evident, although capillaries are small and incon spicuous. Multinucleated giant cells are present through out the connective tissue stroma, and they may be seen in focal aggregates or patches (zonation phenomenon) or distributed evenly (Figures 12-24 and 12-25). Foci of oste oid may be present, particularly around the peripheral margins of the lesion. Numbers of mi to tic fgures, cel lularity, giant cell numbers, giant cell nuclei numbers, and giant cell pattern are not useful in predicting behavior or outcome.

Clinical Features More than half of central hemangiomas of the jaws occur in the mandible, especially the posterior region. A frm, slow-growing, asymmetric expansion of the mandible or maxilla is the most common patient com plaint. Spontaneous gingival bleeding around teeth in the area of the hemangioma may also be noted. Bruits or pulsation of large lesions may be detected with careful auscultation or palpation of the thinned cortical plates. Trophic efects of the hemangioma Giant cell tumors, although rare, have been reported in the on adjacent hard and soft tissues are common.

Tese lesions exhibit a greater tendency to recur after treat ment than do giant cell granulomas. Although to o few cases have been reported in the jaws to predict recurrence rates, it is noteworthy that 30% of lesions in long bones recur after curettage.

Monos to tic and polyos to tic forms of the disorder may afect virtually any bone of the body. The skull, mandible, ribs, vertebrae, and long bones are often involved (Figure 12-29). Loosening of teeth in the area of the afected alveolar bone is a common occurrence. Bone lesions with a sharply circumscribed, sal lesions in the form of submucosal nodules, ulcers, and punched-out appearance may occur in the central aspect of leukoplakia have been described.

Cervical lymphadenopathy, mas to iditis, and otitis media are head and neck manifestations that often present with multifocal involvement. Tese cells most often are arranged in sheets and may be admixed with various numbers of eo sinophils and other infamma to ry cells (Figure 12-32). The ultrastructure of the tumor cells shows unique, rod-shaped cy to plasmic structures, which are identical to Birbeck granules, present in normal Langerhans cells (Figure 12-33). Under these conditions, a diferential diagnosis should include juvenile or diabetic periodontitis, hypophosphatasia, leukemia, cyclic neutro penia, agranulocy to sis, and primary or metastatic malig nant neoplasms.
