In a normal young man the ESR is usually less than 20 mm buy 400 mg floxin free shipping virus vs cold. Another test of inﬂammation is called CRP (C-reactive protein) generic floxin 400mg without prescription infection mercer; this is less likely to be inﬂuenced by extraneous factors. There is no association with a blood test called rheumatoid factor (associated with rheumatoid arthritis) or antinuclear antibodies (associated with lupus). Therefore, AS and related spondylo- arthropathies are sometimes listed under the term seronegative spondyloarthritis. Laboratory analysis of the joint (synovial) ﬂuid obtained by joint aspiration (arthrocentesis) or biopsy (obtained by a needle or by arthroscopy via thefacts 97 AS-14(95-100) 5/29/02 5:52 PM Page 98 Ankylosing spondylitis: the facts an instrument called arthroscope) does not markedly distinguish AS from other inﬂammatory rheumatic diseases. The possible use of HLA-B27 as an aid to diag- nosis is discussed in Chapter 16. New York criteria The current criteria for the diagnosis of AS, known as the modiﬁed New York criteria, are shown in Table 2. Table 2 The generally accepted criteria for AS (modiﬁed New York criteria) 1 Low back pain of at least 3 month’s duration improved by exercise and not relieved by rest 2 Limitation of lumbar spinal motion in sagittal (sideways) and frontal (forward and backward) planes 3 Chest expansion decreased relative to normal values for the same sex and age 4 Bilateral sacroiliitis grade 2–4 or unilateral sacroiliitis grade 3 or 4 Deﬁnite AS if criterion 4 and any one of the other criteria is fulﬁlled. Note: These are classiﬁcation criteria used for case deﬁnition and are primarily designed for research purposes. Other causes of back pain There are many possible cause of back pain, but by far the most common is mechanical deterioration of the spine. This can take many forms, but is often related to the intervertebral discs. In childhood the central part of these discs consists of over 85% water; there is a slow but steady decrease with aging, 98 thefacts AS-14(95-100) 5/29/02 5:52 PM Page 99 Radiology and diagnosis down to about 60% by the age of 80 years. As a result the volume of the disc decreases, leading to narrowing of the disc space, causing buckling of the surrounding ligaments (annulus ﬁbrosus and spinal ligaments), and formation of a bony spur (osteo- phyte) at the edges of the spinal vertebral bodies. Clinical back pain related to disc degeneration increases with age, and is accelerated by mechanical stress. Ankylosing hyperostosis, also called Forestier’s disease or diffuse idiopathic skeletal hyperostosis (DISH), can cause excessive new bone formation along the spine and some other sites. This can result in a stiff spine that may be confused with AS. Other diseases that may be confused with AS include osteitis condensans ilii, Paget’s disease (of the pelvis and spine), and Scheuermann’s disease. The spread of cancer to the pelvis and the spine, as well as some chronic spinal infections, can also present as back pain. A bone-thinning disorder called osteomalacia, which results from dietary deﬁciency of vitamin D and lack of adequate skin exposure to sunlight, or may be a result of chronic kidney failure, can cause back pain and may be mistaken for AS or related spondyloarthropathies. Another illness that can cause confusion is a very rare disease of unknown cause, known as SAPHO syndrome (because of its salient features: synovitis, acne, palmoplantar pustulosis, hyperostosis, and aseptic osteomyelitis). This disease causes bone damage that sometimes affects the sacroiliac joints or the spine. As explained in Chapter 3, the disease usually begins as an inﬂammation in the sacroiliac joints. When these joints become inﬂamed they cause pain that you can feel not just over the joints but diffusely over the buttock (gluteal) area. The sacro- iliac joints usually become tender on direct ﬁrm pressure in the early stages, but the pain and ten- derness gradually get less over the years as the sacroiliac joints become fused and replaced by bone. When the inﬂammation spreads to involve the lumbar spine, you will be aware of low back pain and stiffness. The inﬂammation and pain can result in muscle spasm and tenderness, as well as stiffness of the back. There is a natural tendency to stoop forward to mini- mize the symptoms, because backward stretching is uncomfortable. This can gradually lead to irreversible bad posture, because if the inﬂammation is not resolved the body begins a gradual repair process that results in further limitation of back motion due to thefacts 101 AS-15(101-110) 5/29/02 5:52 PM Page 102 Ankylosing spondylitis: the facts (a) (b) (c) Figure 17 The effects of AS on posture: (a) A healthy person standing erect: Note the hollow lower (lumbar) back and the inclination of the pelvis.

Sarcomas arising in radiation ports are more resistant to chemotherapy B order 400 mg floxin otc antibiotics for sinus infection diarrhea. Her risk of developing a sarcoma after radiotherapy was 10% C purchase floxin 400 mg visa antibiotic 3 days. Her case is unusual in that most cases of sarcoma related to radiothera- py occur approximately 40 years after exposure to radiation D. The most common type of sarcoma associated with previous radiother- apy is not osteosarcoma but rather leiomyosarcoma Key Concept/Objective: To know that radiotherapy is a risk factor for sarcoma Patients who have undergone radiotherapy are at increased risk for developing sarcoma. Sarcomas arising in radiation ports are more resistant to chemotherapy. The risk of a sec- ondary sarcoma after radiation exposure is substantially less than 1%, and the patient is typically exposed to radiation 4 to 20 years before the development of sarcoma. Most radi- ation-associated sarcomas are osteosarcomas. A 55-year-old man presents for evaluation of an enlarging mass in his left upper extremity. It is painless, and the only reason he is concerned is because it contin- ues to enlarge. Results of CT scanning and biopsy are consistent with soft tissue sarcoma. Which of the following statements regarding this patient is true? The grade of the tumor is based on the amount of necrosis seen on imaging B. His prognosis would be better if he had an intra-abdominal or retroperitoneal tumor C. The 5-year survival rates for patients with sarcomas (excluding intra- abdominal and retroperitoneal sarcomas) are similar when corrected for grade, size, and depth D. Patients with high-grade tumors have an unusually poor prognosis, even when the tumors are less than 5 cm Key Concept/Objective: To understand the basic principles regarding the grading and staging of sarcomas, as well as prognosis Staging of sarcomas is based on tumor size, grade, and depth. The 5-year survival rates for patients with soft tissue sarcomas arising in different anatomic sites are similar when cor- rected for grade, size, and depth, except for intra-abdominal and retroperitoneal tumors, which tend to be large and to invade vital organs, even if they are low grade. Patients with low-grade, superficial tumors tend to do well if the tumors are adequately resected. Even patients with high-grade tumors have a good prognosis if the tumors are less than 5 cm in diameter. Tumor grade is based largely on the number of mitoses per high-powered field (magnification, 10×). A patient is referred to you by his dermatologist for evaluation of a soft tissue mass on his leg. You obtain an MRI of the primary lesion and a CT scan of the chest, because you are concerned about the possibil- ity of soft tissue sarcoma. You recommend that an incisional biopsy be performed for definitive diagno- sis. The patient wants to know how you would treat such a tumor. Which of the following is true regarding the general treatment of soft tissue sarcomas? Soft tissue sarcomas are usually well encapsulated and are seen to have clear margins on resection B. Local control of soft tissue sarcomas consists of surgical resection, often with radiotherapy C. Chemotherapy is never indicated for soft tissue sarcomas D. The presence of necrosis on MRI suggests a low-grade sarcoma Key Concept/Objective: To understand the basic principles of sarcoma therapy The goals of the treatment of sarcomas are local and systemic control of the sarcoma; preservation of the extremity or organ function; and quality of life. Local control of a soft tissue sarcoma is generally achieved by surgical resection, which is often combined with radiotherapy. Low-grade tumors push aside contiguous structures, whereas high-grade tumors invade adjacent organs and have large areas of necrosis. Soft tissue sarcomas grow along histologic planes and are usually pseudoencapsulated (i.
They may also be asso- ciated with hereditary diseases or with a peculiar bone structure of the pelvis and rachis discount 200 mg floxin fast delivery bacteria yellowstone hot springs. Nearly always floxin 200mg sale antibiotics enterococcus, however, they are associated with postural or foot alterations that should be studied dynamically for the diagnosis. Although they often elicit changes in the ﬁgure and cause the true cellulite disease, deﬁnite assistance for such alterations is not always possible because they sometimes require physical therapy and a change in lifestyle. Systemic and localized adiposity: The general contour of the human body derives its characteristics from the particular arrangement of the adipose panniculum upon the structure of bones and muscles. The human body is characterized by the presence of rigid fasciae, particularly, the deep muscular fascia that, starting from the skull base, extends continuously to the ankle and the metatarsus supporting many vascular, neuro-physiological, and orthopedic functions. In certain areas, the fascia is divided 46 & BACCI AND LEIBASCHOFF into two layers of hormone-dependent adipose tissue (steatomery), especially associated with procreation and containing insulin, estrogen, and calcium receptors. Such steato- meric adiposities, in their turn, provide roundness to the ﬁgure. It is also well known that such localized adiposities may only be eliminated through surgical therapy or liposculpture. Alterations in the ﬁgure are mainly determined by disorders in adipose areas, either steatomeric in nature (hereditary and sensitive to endocrine-metabolic signals) or subcu- taneous (sensitive to unbalanced diets, toxic substances, bacteria, and heavy metals). Excessive localized adiposity may involve numerous normal-sized cells (hyperpla- sia), a normal amount of big-sized cells (hypertrophy), or a combination of both. Localized areas of adiposity are frequently found in the lower part of a woman’s body, in the glutei, the abdomen, the ﬂanks, the upper external side of the hip, and the knee. The volume of some adipose tissues is conditioned, to a certain extent, by hormonal activity and should therefore be considered as normal. However, when such adipose char- acteristics do not agree with current aesthetic canons in fashion or when they elicit symp- toms, surgical intervention may be considered legitimate. Localized adiposity should be distinguished, nevertheless, from cellulite itself, even if an association of these two pathol- ogies is frequent. EFP: It is the traditional evolutionary degenerative disease of subcutaneous tissues that develops on a constitutional substrate closely linked with a series of predisposing and triggering factors. Localized areas of cellulite are frequently found in the lower part of a woman’s body, in the glutei, the abdomen, the ﬂanks, the upper external side of the hip, and the knee. PATHOPHYSIOLOGY OF CELLULITE & 47 According to the authors who described its histomorphology, it involves a sequence of events characterized by interstitial edema, connective ﬁbrous reaction, and the resulting sclerotic evolution. Each of these histopathological stages is associated with a different vascular stage (15,16). Thus T0 indicates normal vascularization, T1 the initial appearance of hypoxic areas, T2 the presence of hypoxic and hypometabolic areas, and T3 and T4 indicate the cold nodular evolution characterized by a thermographic plate resembling the skin of a leopard (70). Clinical studies and recent observations have demonstrated that EFP effectively repre- sents some types of the cellulite disease though it does not cover all clinical manifestations. Very few women above 18 years of age are totally free from cellulite. Nearly always the process starts in puberty, affecting particularly the lower limbs. Other triggering periods are pregnancy, periods of sexual dissatisfaction, lack of human or family understanding in combination with an altered lifestyle, wrong diet, and intestinal dysfunc- tions. Very few women above 18 years of age are totally free from some form of cellulite. WHAT IS THE RELATIONSHIP BETWEEN CELLULITE AND OBESITY? A clear distinction between cellulite and obesity should be made, even though confusion is frequent. Though they may coexist, the two processes are deﬁnitely different. When fatty tissues exceed the normal value of 30%, there is obesity. A diet that 48 & BACCI AND LEIBASCHOFF is poor in nutrients and aimed at reducing localized volume has an initial harmful con- sequence: tissues lose their structure and different areas slim down.
