Prednisone

Melasma Melasma is characterized by irregular cheap prednisone 10mg amex, usually symmetrical brown patches on sun-exposed skin buy 10 mg prednisone. Melasma is not exclusively a disorder of the darker skin types, but it appears to be far more common in Hispanics, Asians, and blacks. Current treatment options include the use of sun blocks, hypopigmenting agents, and chemical peels [15]. The two processes involved are epidermal hyperpigmentation and/or dermal hyperpigmentation (incontinentia pigmenti). The hyperpigmented areas correspond with the distribution of the original dermatosis. Blacks seem to have more follicular skin problems, and post-acne hyperpigmentations in the face are very common. The primary goal of therapy is treatment of the underlying Pigmentary Disorders in Black Skin 15 inammatory disease. However, caution is necessary as many of these agents can induce irritation making the problem worse [17,18]. Postinammatory hypopigmentation Postinammatory hypopigmentation is caused by various cutaneous inammatory diseases. The long use of potent corticosteroids, chemical peelings, and medical interventions (laser, peels) can also play a role [19]. In postinammatory hypopigmentation, the melanocytes react with decreased melanin production after an inammation or trauma. Sun- light exposure or photo (chemo) therapy may lead to repigmentation within months. Pityriasis alba Pityriasis alba is an eczematous disorder often occurring in children with an atopic background and dry skin. In many cases, it is hardly noticeable on white skin; the disorder can be very conspicuous in black-skinned chil- dren. Sun exposure in conjunction with topical steroids or calcineurin inhibitors and correction of the xerosis cutis is usually effective [20]. This der- matosis affects all races, is more frequent in women, and tends to increase in incidence with age. The etiology and pathogenesis are not well under- stood, but since the lesions appear mainly on sun exposed areas, actinic damage may be a causal factor [21]. The disease is seen all over the world and in all skin types, affecting approx- imately 0. In many patients with active vitiligo, the Koebner phenomenon can be observed; new lesions appear on injured or irritated skin. It is important to differentiate between generalized vitiligo, the most common form with lesions distributed in a more or less symmetrical way and segmental vitiligo, more seen in children, where lesions develop in a unilateral and usually limited way [23]. Generalized vitiligo is considered to be an autoimmune disease and is associated with other autoimmune diseases like thyroid disease, type-1 diabetes, and so on. In many patients, it runs a chronic course with stable periods sometimes with partly repigmentation interchanged by relapses leading to more and larger lesions. Segmental vitiligo shows a rapid course that stops in a couple of years, leading to stable spots refractory to the usual medical therapies like pho- totherapy, topical steroids, and calcineurin inhibitors. On the other hand, grafting techniques that replenish the reservoir of melanocytes by grafts from another body region are very successful in these patients, leading to a lasting recovery in most of them. Understandingly, vitiligo in dark-skinned patients is much more disg- uring than in whites, leading to a more quality-of-life issues [24]. Because of the resemblance to leprosy, vitiligo patients in areas with endemic lepra often suffer from social exclusion. Melanoma Dark skin is better protected from sunlight, making sun-induced cancers less prevalent. However, at this moment there is a trend toward increased skin cancer rates in most ethnic groups [25,26]. The prognosis of melanoma is related to the stage of the disease at the time of presentation. African Americans diagnosed with melanoma have a worse prognosis than whites because they are initially seen with a more advanced disease [27] and the same is found in other black-skinned populations [28]. The most common type of melanoma found in African Americans type is the acral lentiginous growth pattern, whereas in whites, the trunk is the most com- mon site [29,27]. Pigmentary Disorders in Black Skin 17 Progressive macular hypomelanosis Progressive macular hypomelanosis is characterized by nonscaly, nonitchy, ill-dened hypopigmented macules on the skin. The macules occur on the front and the back of the trunk (less frequent on the face, the neck and the upper extremities) and are conuent in and around the midline. It occurs in young adults of both sexes but more often in women and can be found all over the world, especially in black populations.

The generic term for such indicators is health expectancies and they are summary measures of population health combining information on survival with the prevalence of a health measure (Robine 2006). The most common health measure used is disability, producing disability-free life expectancy. Background to health expectancies Research on health expectancies dates back to the 1960s. Being independent of the size of populations and of their age structure, health expectancies allow direct comparison of the different groups that make up populations: e. Since that time health expectancies have been increasingly used in developed countries to assess the evolution of a population s health status, in particular that of older people (Robine et al. However comparison between countries remained almost impossible due to national differences in the morbidity data collected, particularly in the study design, the health concepts used and the wording of questions. In total 10 instruments were proposed with their exact wording in English (Box 1). The set allows in theory the computation of many health expectancies covering the totality of the conceptual framework of the measurement of population health. Similar methodology was used in the development of the 10 health indicators: a systematic review of the literature on the concept and wording of questions and their previous use in surveys. Do you suffer from (have) any chronic (long-standing) illness or condition (health problem)? For the past 6 months or more have you been limited in activities people usually do because of a health problem? Ultimately 9 indicators were chosen: chronic morbidity (global and detailed); activity limitation (global); perceived health (global); physical and sensory functional limitations; personal care activities; household care activities; other activities; and mental health. Indeed it is crucial that even if existing 293 items are taken from current European Surveys, existing translations are not automatically taken but that new translations following a standard scientific protocol are undertaken. However 2003-2004 was a transitional period, during which data were provided by national sources with post- harmonisation giving a break in series. Considerable disparities are evident between the European Member States in the level of chronic morbidity reported by the population. The reported prevalence in women is higher than that for men within every Member State though the gender gap varies from 2. However men and women give the same picture of the diversity of chronic health problems reported in Europe. Briefly this entails applying the age and gender specific prevalence of chronic morbidity, presented in the previous section, to the life table for the corresponding years of the survey from which the prevalence data were obtained. The gender gap in life expectancy at age 65 within Member States in 2005 was only 2. There appeared to be little relationship between the increase over the period 1995 -2005 and life expectancy at age 65 in 1995 for either men or women. Thus there was no evidence that Member States with the highest life expectancies at the beginning of the period were showing signs of reaching a maximum value. On average increases in the later period were marginally greater than those in the early period. Increases in the two periods remained constant in Austria, Portugal, Sweden and United Kingdom in men and Austria in women. In Lithuania for both men and women life expectancy at age 65 declined in the period 2000-2005. Years with chronic morbidity at age 65 Applying the prevalence of chronic morbidity within age groups to the life tables gives the expected years spent with chronic morbidity. As with most health measures women spend a greater number of years but also a greater proportion of their remaining longer life with chronic morbidity. The evidence from Europe does not appear to support that Member States with longer life expectancy have longer healthier life expectancy or rather that they have less life expectancy with chronic morbidity. However there appears little evidence that Member States with the lowest proportion of unhealthy life (spent with chronic morbidity) are also those with the longest overall life expectancy at age 65. Health expectancies such as life expectancy with chronic morbidity offer the means to monitor that reducing the longevity gaps in Europe and increasing life expectancy will be accompanied by better health and quality of life.
