Achilles tendinitis and plantar fasciitis caused a severe talalgia and they were observed mainly in males with Reiter's syndrome or ankylosing spondylitis. On the other hand, sub-Achilles bursitis more frequently affected women with rheumatoid arthritis and rarely gave rise to severe talalgias.

  • REPETITIVE STRAIN INJURY AWARENESS Tenosynovitis
    REPETITIVE STRAIN INJURY RSIA AWARENESS Tenosynovitis RSI Conditions The term Repetitive Strain Injury is an umbrella term used to describe a number of specific musculoskeletal conditions, including tenosynovitis, as well as ‘diffuse RSI’, which is more difficult to define but which recent research attributes to nerve damage. These conditions are often occupational in origin. Lack of adequate diagnosis or access to appropriate treatment can exacerbate the condition and sometimes leads to job loss and economic hardship. What is Tenosynovitis? Tenosynovitis is the tender swelling of the rope or cord like structures (tendons) which connect muscles to the bones in order to work the joints of the body, and inflammation of the lining of the protective synovial sheath that covers these tendons. Areas most frequently affected are the hand, wrist or arms, although it may occur at any tendon site. De Quervain’s or Stenosing Tenosynovitis results from inflammation or constriction of the tendons on the thumb side of the wrist. A localised swelling affecting the flexor tendons of the hand is known as Trigger Finger. The Symptoms When the gliding surfaces of the tendon and sheath become roughened and inflamed from overuse, tenosynovitis will present as aching, tenderness and swelling of the affected area. There may also be also stiffness of the joint, shooting pains up the arm and creaking tendons (crepitus). The ability to grip can be lost. A localised swelling at the base of the thumb may indicate De Quervain’s. Tenosynovitis can just last a few days, but in some cases may go on for many weeks or even months.

  • Adult Still's Disease
    44 y/o male who reports severe knee pain with daily fevers and rash. High ESR, CRP add negative RF and ANA on labs. Edward Gillis, DO ? Adult Still’s Disease Frontal view of the hands shows severe radiocarpal and intercarpal joint space narrowing without significant bony productive changes. Joint space narrowing also present at the CMC, MCP and PIP joint spaces. Diffuse osteopenia is also evident. Spot views of the hands after Tc99m-MDP injection correlate with radiographs, showing significantly increased radiotracer uptake in the wrists, CMC, PIP, and to a lesser extent, the DIP joints bilaterally. Tc99m-MDP bone scan shows increased uptake in the right greater than left shoulders, as well as bilaterally symmetric increased radiotracer uptake in the elbows, hands, knees, ankles, and first MTP joints. Note the absence of radiotracer uptake in the hips. Patient had bilateral total hip arthroplasties. Not clearly evident are bilateral shoulder hemiarthroplasties. The increased periprosthetic uptake could signify prosthesis loosening. Adult Stills Disease Imaging Features • Radiographs – Distinctive pattern of diffuse radiocarpal, intercarpal, and carpometacarpal joint space narrowing without productive bony changes. Osseous ankylosis in the wrists common late in the disease. – Joint space narrowing is uniform – May see bony erosions. • Tc99m-MDP Bone Scan – Bilaterally symmetric increased uptake in the small and large joints of the axial and appendicular skeleton.

  • Arthritis and Joint Pain
    Fact Sheet News from the IBD Help Center ARTHRITIS AND JOINT PAIN Arthritis, or inflammation (pain with swelling) of the joints, is the most common extraintestinal complication of IBD. It may affect as many as 30% of people with Crohn’s disease or ulcerative colitis. Although arthritis is typically associated with advancing age, in IBD it often strikes younger patients as well. In addition to joint pain, arthritis also causes swelling of the joints and a reduction in flexibility. It is important to point out that people with arthritis may experience arthralgia, but many people with arthralgia may not have arthritis. Types of Arthritis • Peripheral Arthritis. Peripheral arthritis usually affects the large joints of the arms and legs, including the elbows, wrists, knees, and ankles. The discomfort may be “migratory,” moving from one joint to another. If left untreated, the pain may last from a few days to several weeks. Peripheral arthritis tends to be more common among people who have ulcerative colitis or Crohn’s disease of the colon. The level of inflammation in the joints generally mirrors the extent of inflammation in the colon. Although no specific test can make an absolute diagnosis, various diagnostic methods—including analysis of joint fluid, blood tests, and X-rays—are used to rule out other causes of joint pain. Fortunately, IBD-related peripheral arthritis usually does not cause any lasting damage and treatment of the underlying IBD typically results in improvement in the joint discomfort. • Axial Arthritis. Also known as spondylitis or spondyloarthropathy, axial arthritis produces pain and stiffness in the lower spine and sacroiliac joints (at the bottom of the back).

Abstract Background: Pain is a common and unavoidable phenomenon in childbirth, and in terms of severity, childbirth pain is among the most severe pains in human. Objectives: The current study aimed at investigating the effect of localized heat and cold therapy on pain intensity, duration of phases of labor, and birth outcomes among primiparous females. Satisfaction was also compared in the two intervention groups. Methods: The current randomized, controlled trial was conducted on 120 primiparous females in three groups (heat/ cold therapy, and control) from September 2015 to January 2016. Intensity of pain, duration of phases of labor, and birth outcomes were mea- sured before and after intervention in the three groups. Satisfaction with localized heat and cold therapy was compared in the two intervention groups.
