Leg length discrepancy is one of the causes of pronated feet. It would be logical to correct it as part of the conservative treatment, although up to now there are no studies relating to leg length discrepancy and anterior knee pain.

With regard to the embarrassment caused by the presence of cellulite in the practice of sports, the answers both before and after treatment were very similar. The results suggest that, for women, 4 & HEXSEL AND HEXSEL exposing the body during sports is not as embarrassing as other situations, as for example during sexual relations. According to Jorge (10), the psychological impact and the impact in interpersonal relations, respectively, is more prejudicial for women than for men. Studies that evaluated patients with dermatosis, carried out in Sweden and Norway, suggest that those at risk of the greatest harm are females who are young and in whom the disease exists over an extended period of time (10). As cellulite appears basically in women, this condition should be investigated in terms of its impact on QOL. Ten attributes were evaluated: physical symptoms, feelings, daily routine, clothing, social and leisure, sport and exercise, work and study, personal relations, sexual relations, and treatment. Of these, only the degree to which the condition affected the practice of sports and exercise was the score given by males higher than that given by women (15). This shows that the practice of sports may have greater signiﬁcance in the male group than in the female. We also checked the impact of treatment on the QOL of patients with cellulite. Each patient attributed a value from 0 to 9, with 0 representing very low self-esteem in relation to the fact of having cellulite, and 9 representing very high self-esteem. The clinical evalua- tion considered the improvement on the left and right sides, which were treated differently. Even without any improvement in the degree of cellulite noted by the examiner, there was an increase in self-esteem (evaluated from 0 to 9) after treatment. This improvement can be seen in the difference in the percentage of scores found before and after treatment. This shows that the treatment did have a positive effect on the self-esteem of the patients, indi- cating that the simple fact of treating the cellulite and caring for themselves, even in the absence of any clinical improvement, inﬂuenced the well-being of the patients, who described themselves as better and more conﬁdent following the treatment. It may suggest that treatments should be tried, even if there is no cure for this condition. It is interesting to note that, even without techniques that can guarantee signiﬁcant improvement of cellulite in its different degrees, cosmetic patients want alternatives and their emotional improvement is not directly related to clinical improvement. Care and atten- tion to cosmetic problems can lead to improvement in the emotional state of the patients. Cellulite has a real impact on the QOL of patients, as it restricts those that suffer from the condition in everyday situations and activities. This causes damage in the psycho- logical area in interpersonal relationships, as also occurs with other conditions that afﬂict the skin. It is important that the doctor not only offers a diagnosis of and treatment for the patient’s condition, but also attempts to understand the impact that the condition has on the life of patients, their beliefs regarding the problem, and their expectations regarding the cure or treatment.

Many varieties of these 112 thefacts AS-16(111-124) 5/29/02 5:55 PM Page 113 HLA-B27 and the cause of ankylosing spondylitis genes at these various loci exist in the general popu- lation generic vardenafil 10 mg online erectile dysfunction from anxiety, so it is very difﬁcult to ﬁnd two unrelated individuals possessing an exactly identical combina- tion of these variations 10mg vardenafil with mastercard erectile dysfunction doctors in st. louis. The presence of the viral peptide antigens with the HLA molecule activates CD8+ cytotoxic T cells speciﬁc for that peptide antigen to destroy the infected cell. The role of HLA-B27 in disease predisposition A greater prevalence of AS is observed in HLA- B27-positive ﬁrst-degree relatives of AS patients than in HLA-B27-positive random controls. This suggests that AS is probably genetically heteroge- neous, i. However, the evidence favors the gene for HLA-B27 being the major genetic susceptibility factor responsible for AS. The more disease-predisposing genes you inherit the more likely you are to suffer from AS, but most likely it still requires some, as yet unknown, environmental (i. Although people who are born with the HLA- B27 gene are more predisposed to AS or one of the related spondyloarthropathies (i. It is important to emphasize that there are far more people in the general population with HLA-B27 who never get AS than those who do. Even in families where one member has the thefacts 113 AS-16(111-124) 5/29/02 5:55 PM Page 114 Ankylosing spondylitis: the facts disease and the HLA-B27 gene, most of their brothers and sisters will remain unaffected even when they have the same gene. Perhaps the HLA-B27-positive person destined to develop spondyloarthropathy may be exposed to certain gut organisms that partially imitate HLA- B27 in ways that lead the bacterial antigens to become immunogenic and somehow trigger the disease. The HLA-B27 protein itself or the peptide bound to and derived from HLA-B27 may have a pathogenic role. Inheritance of HLA-B27 Each of us has 46 chromosomes in the nucleus of our cells, and each chromosome is a tiny thread-like structure that contains a set of genes. We derive 23 of our chromosomes from one parent and the other 23 from the other parent. Autosomes is the name given to the 22 of these pairs of chromosomes that are unrelated to the sex of the person; they are assigned numbers 1 through 22, based on their size. The remaining two chromosomes are assigned the letters X and Y, and they are the sex chromosomes. Each female has two X chromosomes and each male has an X and a Y chromosome. The father contributes a set of 22 autosomes and an X or a Y chromosome to the offspring, while the mother contributes the other set of 22 autosomes and the X chromosome. Everyone has two HLA-B genes (one on each chromosome 6), and someone is said to be HLA- B27 positive if B27 is the gene present at either one or both of these HLA-B gene locations. There is then a 1 in 4 chance that the offspring from such a marriage will inherit B27 from both parents (B27 homozygous), a 1 in 2 chance of inheriting the B27 gene from only one parent (B27 hetero- zygous), and a 1 in 4 chance of not inheriting the B27 gene at all. Genetic counseling Because of this genetic predisposition, it is not unusual for more than one person in a family to be affected with AS or related diseases, and it is helpful for the doctor to know this family history. A person with AS (who has a >90% chance of possessing the HLA-B27 gene if he or she is of Western European extraction) may ask, ‘What is the risk of my children developing it, and can anything be done to prevent this? Thus, most children with the B27 gene do not develop the disease, and the 50% of children who lack the gene carry no virtually increased risk unless thefacts 115 AS-16(111-124) 5/29/02 5:55 PM Page 116 Ankylosing spondylitis: the facts genes for other diseases that also predispose to AS (such as psoriasis and inﬂammatory bowel disease) are present in the family. If the person with AS does not possess HLA-B27 (a <10% chance if he or she is of Western European extraction), then the risk of disease occurrence among the children may not be increased at all, unless genes for other diseases that also predispose to AS (as mentioned above) are present in the family. The person with AS, who has a >90% chance of possessing the HLA-B27 gene, may ask, ‘Should I have all my children tested for the HLA-B27? Moreoever, the parents and the healthcare providers may get ‘HLA-B27-itis’: knowing that the child has HLA-B27, the parents and the healthcare providers can worry unneces- sarily; and symptoms unrelated to AS may be wrongly attributed to the fact that the child has inherited the gene. Thus the child may get a wrong diagnostic label of AS, even though he or she is an unaffected individual who happens to possess a normal gene called HLA-B27. Even a child who remains totally healthy may suffer indirectly in future if the information about the HLA-B27 test result enters their medical records, and thus becomes available to health insurance agencies, or future potential employers, who may misuse such information. If a child of an AS parent develops symptoms or signs that you suspect may be due to AS or another HLA-B27 associated disease, you should point out 116 thefacts AS-16(111-124) 5/29/02 5:55 PM Page 117 HLA-B27 and the cause of ankylosing spondylitis all the child’s symptoms to their doctor, who should preferably be a pediatric rheumatologist. When it is appropriate the doctor can utilize HLA-B27 typing as an aid to diagnosis. HLA-B27 testing in disease diagnosis AS can almost always be readily diagnosed on the basis of history, physical examination and X-ray ﬁndings, and therefore HLA-B27 typing is not necessary for disease diagnosis. A knowledge of the presence of HLA-B27 can sometimes be valuable as an aid to diagnosis, although the prevalence of HLA- B27 (Table 3) and the strength of its association with AS vary markedly in different ethnic and racial groups. For example, only 50% of African– American patients with AS possess HLA-B27, and it is close to 80% among AS patients from Mediterranean countries. Thus, AS and related diseases can also occur in people who do not have HLA-B27. Therefore, a negative test result for B27 does not, in itself, completely exclude the presence of the disease. Moreover, a positive test result in itself does not mean that someone has the disease, because the HLA-B27 gene is present in a signiﬁcant percentage of the healthy general population. However, the test can be useful for a doctor who understands the principles of probability reasoning and uses it only in a toss-up clinical situation.
