Cows are not usually severely lame but digital dermatitis (or papular digital dermatitis). Since Chapter 11 • Musculoskeletal Disorders 475 1994 the disease has developed to epidemic propor- tions in most of Europe and spread throughout the United States. One wonders why a disease that was re- ported originally in 1974 suddenly spread worldwide in dairy cattle in the past few years. Currently researchers are still trying to define the specific cause(s); several strains of spirochete bacteria of the genus Treponema are believed to be responsible for the disease. Histological specimens of lesions stained with silver that demon- strate spirochetes reveal their presence in great numbers throughout the stratum spinosum of the dermis. The earliest lesion recognizable as digital dermatitis is a reddened circumscribed area typically just above the interdigital cleft on the plantar aspect of the pastern, the strawberry form of digital dermatitis. The most striking feature of the lesion is the degree of pain expressed by the cow (Figure 11-19). Hairs at the periphery of the lesion are often erect and matted in exudate to form a rim. As the lesion progresses, focal hypertrophy of the dermis and epidermis leads to raised conical projections appear- ing much like wet, grey terrycloth. In even later stages, papilliform projections of blackened keratin may extend 10 to 15 mm from the surface, the hairy wart stage. Typi- cal lesions may be seen affecting any of the limbs, but Figure 11-20 rear limbs are more commonly involved. The location Digital dermatitis lesion at the skin-heel horn junction and extent of affected skin are variable and include inter- with erosion of heel horn and extension of the digital digital skin, anterior and posterior margins of the inter- dermatitis into the solar region.

Menopause is a stage that favors weight gain and development or worsening of obesity speman 60caps visa, and causes of this problem are many; some are clearly related to hypoestrogenism and oth‐ er age-dependent purchase speman 60caps with mastercard, conditioning increased intake and decreased energy expenditure [22, 23] (Figure 4). Other disorders such as obesity and metabolic syndrome also occurs at menopause, suggesting that menopause may be the trigger of the metabolic syndrome at that stage of life [27, 28]. Postmenopausal women have higher insulin resistance than premenopausal, which could participate to age, the increase in total body fat, central adiposity, estrogen deficiency, alter‐ ations in lipid profile and glucose homeostasis and insulin are more frequent and favor the high cardiovascular morbidity and mortality after menopause. In this sense the transition of menopause is marked by changes in hormonal balance, with increased visceral fat, which are associated with insulin resistance, although it has been found that the change in insulin sensitivity does not alter the lipid profile in early postmenopausal women [24, 26] (Figure 5). Pro and antioxidants propierties of estrogens Throughout menopause there are factors that predispose women to the development of oxi‐ dative stress, such as estrogen deficiency, as it has been confirmed that they have an antioxi‐ dant capacity independently of its binding to receptors, so for example the 17β-estradiol (E2), estriol, estrone, ethinylestradiol and 2-hidroxiestradiol besides reducing neuronal death with antioxidant activity, due to the presence of an intact hydroxyl group on ring A of the molecule [33]. Estrogens are synthesized from different androgen precursors such as androstenedione and testosterone, yielding as products estrone and 17β-estradiol, respectively. The toxic effect of 4-hydroxyestrogens probably is prevented under normal conditions intracel‐ lular defense mechanisms. Oxygen free radicals can be removed immediately transformed into water by enzymes such as catalase and superoxide dismutase and antioxidant vitamins 294 Oxidative Stress and Chronic Degenerative Diseases - A Role for Antioxidants such as ascorbic acid and alpha tocopherol, quinone themselves can be inactivated by sulfo compounds, such as glutathione [36]. In addition, estro‐ gen induces the expression of oxide reductasesthiol / disulfide, such as disulfide isomerase, thioredoxin, thioredoxinreductase and glutaredoxin in the endothelium and inhibits apopto‐ sis mediated by hydrogen peroxide. Oxidative stress and postmenopause Actually several oxidative stress biomarkers have been studied in menopause, however, each researcher has used different marker, methodologies and women with dissimilar char‐ acteristics (age, ethnic group, postmenopause time), fact does difficult to make a conclusion about the development of oxidative stress during peri, menopause and postmenopause. Serum γ-glutamyltransferase, glutathione and malondialdehyde levels in the pre- and postmenopausal women [43]. Data showing departures from normality are expressed as median values with the respective lower and upper quartile. Another finding is the lipoperoxide level which was significantly increased in perimeno‐ pausal women (Table 3). Data showing departures from normality are given as median values with the respective lower and upper quartile. Profile oxidant and antioxidant between premenopausal and perimenopausal women [44]. Pansini demonstrated that the total body fat mass increases significantly in postmenopause in comparison with premenopause, with specific increases in fat deposition at the level of trunk (abdominal and visceral) and arms. Concomitantly, the antioxidant status adjusted for age showed that antioxidant status was retained. Also both antioxidant status and hydro‐ peroxide level increased with trunk fat mass [46]. Risk factors for higha 2 lipoperoxide levels, as oxidative stress biomarker, in perimenopausal women [49]. They are very sen‐ sitive to oxidation caused by excess free oxygen radicals and the consequent oxidative sta‐ tus, and it is well known that lipid and lipoprotein metabolism is markedly altered in postmenopausal women as it was demonstrated by Signorelli who founded that the oxida‐ tive stress is involved in the pathophysiology of atherosclerosis. Lipo‐ peroxides, erythrocyte superoxide dismutase and glutathione peroxidase activities, the total antioxidant status, pro-oxidant factors, body mass index were evaluated. The lipoperoxide levels were significantly higher in the postmenopausal group than in the premenopausal group, which concluded that menopause is the main risk factor for oxidative stress [49]. Postmenopausal women also exhibited a higher total radical antioxidant level [50]. Associated diseases to oxidative stress There are several evidences that related to oxidative stress with diseases present in postme‐ nopausal women in example depression, osteoporosis, cardiovascular diseases and leg vaso‐ constriction. This disorder has cerebral implications, as showed post-mor‐ tem studies in patients with depressive disorder pointed a significant decrease of neuronal and glial cells in cortico-limbic regions which can be seen as a consequence of alterations in neuronal plasticity. This could be triggered by an increase of free radicals which in its turn eventually leads to cell death and consequently atrophy of vulnerable neuronal and glial cell population in these regions [52]. Actually too is known that estrogen protect neurons against oxida‐ tive damage excitotoxins, and beta-amyloid-induced toxicity in cell culture, reduces the se‐ rum monoamino oxidase levels and might regulate learning and memory. Both oxidative stress and associated polymorphisms are useful tool to predict which patients might devel‐ op osteoporosis. It is known that young women during their fertile life are at lower risk of cardiovascular events compared with men, being protected by estrogen action and that oxidative stress is generally higher in men than in premenopausal women. However, after menopause the risk of experiencing cardiovascular events rapidly rises in women, in conjunction with a parallel increase in oxidative stress. Moreover, al‐ though oxidative stress results are lower in females compared to males during the first deca‐ des of life, this difference decreases until the age range which corresponds to the onset of menopause for women [59]. Further investigations are needed to examine the roll of oxidative stress as an endogenous bioactive agent related to disease in post-menopausal women. Since oxidative stress is the imbalance between total oxidants and antioxidants in the body, any single oxidant/ antioxi‐ dant parameter may not reflect oxidative stress. Further studies are needed to understand the underlying mechanisms of before findings. Estrogens (17β-Estradiol and Estriol) and conjugated equine estrogens, and these are administered orally. Estrogens may adminis‐ trated by oral, subcutaneous routes, also intravaginal estrogen (tablets, creams, ovules), alone or combined with progestin, are suitable for vaginal symptoms, with no significant increase in endometrial hyperplasia or proliferation. They are administered in combination with estrogen to reduce the risk of endometrial hyperplasia and cancer. Progestins are mainly used orally, although there are preparations to be administered in combination with estrogen transdermal route [65]. Tibolone improves vaginal symptoms and no significant differences when compared to estrogen, decreases menopausal symptoms, although moderately increases bone density and inhibit bone resorption.

Pulmonary Kaposi’s Sarcoma In patients with obvious cutaneous Kaposi’s sarcoma, involvement of the mucosal surfaces is frequent (30% to 50% of cases) and, in general, asymptomatic.
