A mutation of the same gene can cause widely differing clinical phenotypes buy 20mg cymbalta visa. For example discount cymbalta 60 mg without prescription, the same mutation of the dysferlin gene may cause either type 2B limb-girdle dystrophy or Miyoshi’s distal myopathy. In the mitochondrial myopathies, or disorders of β-oxidation, combinations of gene defects coding for specific enzymes can significantly modify the clinical phenotype. Unfortunately, the exponential increase in knowledge of genetic defects in specific muscle disorders has not been matched by the diagnostic availability of these tests. Furthermore, the cost of genetic studies has made it imperative that the clinician use consummate diagnostic skills to define the type and extent of testing. Thus, clinical judge- ment still remains the yardstick for diagnosis of a specific myopathy. As effective treatments become aligned with specific genetic and post-translation- al peptide or protein abnormalities, it will become even more important for the physician to develop a superb diagnostic acumen. A Clinical proximal weakness on raising the leg in a patient with severe polymyositis. B Polymyositis showing increased infiltration of muscle fibers by macrophag- es and rare lymphocytes (ar- rows) B Distribution/anatomy Usually affects proximal muscles with sparing of the face. Time course Progressive disorder with gradual onset in most cases. Can occur in children, but usually in those greater than 20 years of age. Clinical syndrome Polymyositis is more common in women (9:1). It usually results in a progres- sive, subacute weakness with muscle pain in approximately 50% of subjects. Cardiac involve- ment with EKG changes may also occur.

Which of the following statements about this patient is most correct? His shortness of breath may very well result from being out of shape B order 60mg cymbalta free shipping. He would benefit from use of ipratropium bromide before exercise C purchase cymbalta 60 mg line. He would benefit from use of a beta agonist before exercise D. He would benefit from use of theophylline before exercise E. He would benefit from use of an inhaled steroid before exercise Key Concept/Objective: To understand the appropriate therapy for exercise-induced asthma The most effective therapy for exercise-induced asthma is an inhaled beta agonist. Cromolyn is also effective, and newer leukotriene modifiers may also have a role. Theophylline, corticosteroids, and anticholinergics have no role in the treatment of exercise-induced asthma. The patient in Question 5 returns to clinic for follow-up 12 weeks later. He mentions that 7 days ago he had a headache, for which he took two aspirin. Later, as the headache began to subside, he also devel- oped itchy eyes and an itchy throat. Which of the following statements about this patient is most correct? Because he does not have nasal polyps, it is unlikely that he has aspirin hypersensitivity B. He is likely to have similar reactions to all NSAIDs C. This reaction was the result of salicylate sensitivity, so ibuprofen should be safe for him to use D. This reaction suggests that he would not benefit from a leukotriene modifier E. A COX-2 inhibitor, such as celecoxib, is likely to be safe for him to use 14 RESPIRATORY MEDICINE 5 Key Concept/Objective: To understand the relationship between asthma and aspirin hypersensitivity Aspirin hypersensitivity can initially present with bronchoconstriction or other allergic symptoms. Cross-reactivity with other NSAIDs is almost universal, because the causal mechanism is likely mediated by COX.

A process of healing and repair generic 40 mg cymbalta otc, which follows the enthesitis phase generic cymbalta 20 mg overnight delivery, results in gradual limitation of back motion due to scarring and subsequent bone thefacts 103 AS-15(101-110) 5/29/02 5:52 PM Page 104 Ankylosing spondylitis: the facts Figure 19 formation. This process may, after many years, lead ultimately to complete spinal fusion. Any clinical examination to look for the presence of AS must therefore include a thorough examination of spinal mobility in all directions (Figure 5), Chapter 3. The inflammatory changes affect the superficial layers of the ligament (annulus fibrosus) that surrounds the disc, especially at its attachment to the corners of the vertebral bodies, resulting in increased bone density (sclerosis) of these corners, seen on X-ray as shiny corners (Figure 19). The bone at these corners may subsequently disappear, and this may ultimately result in squaring of the vertebral bodies. Gradually a thin layer of vertical bony outgrowths at the edges of the vertebrae bridges the gap between the two adjacent vertebral bodies, replacing the superficial layer of the annulus fibrosus of the disc. This intervertebral bony bridging that surrounds the disc is called a syndesmophyte (Figure 19). At the same time, inflammatory changes and slowly progressive bony fusion may be going on in spinal joints called the apophyseal or facet joints (Figure 19). Thus in someone with severe disease the inflammatory process of the spine may gradually, after many years, result in complete fusion (also 104 thefacts AS-15(101-110) 5/29/02 5:52 PM Page 105 The disease process called bony ankylosis) of the whole spine. The X-ray of the spine may ultimately look like a bamboo and is sometimes called bamboo spine. Spinal osteoporosis (discussed earlier) is also fre- quently observed among such patients, partly as a result of the lack of spinal mobility and aging. The inflammation of the joints between the ribs and the spine (the costovertebral and costotrans- verse joints), and at the junction of the ribs to the breastbone in front of the chest (the costochondral areas), can result in chest pain and tenderness. This pain can be accentuated by coughing or sneezing. Over the years there may be a gradual decrease in chest expansion. Therefore, some people may present to the doctor with chest pain and tender- ness, or complain of inability to expand their chest fully on deep inhalation, or shortness of breath on exertion. The doctor should check not only for lim- itation of mobility (in all directions) of the spine, including the neck, but also for any restriction of chest expansion (Figure 5f). Involvement of non-spinal (limb) joints The hip and shoulder joints, the so-called girdle joints, are affected in one-third of AS patients. The hip joint involvement usually affects both sides (bilateral) and is gradual in onset; the pain is usually felt in the groin, although you may feel it in the knee or the front of the thigh on the same side.
