1/3. skin diseases in ghana and the UK.BACKGROUND: Although diseases of the skin have been studied in some African countries, the provision of dermatology services is as yet a relatively underdeveloped aspect of medicine in sub-Saharan africa. OBJECTIVE: To determine the pattern of skin diseases seen in a sub-Saharan community and to compare it with that seen in a European community. methods: The diagnoses of the principal presenting complaint of 2254 consecutive new patients seen at the dermatology clinic of Komfo Anokye teaching Hospital (KATH), Kumasi, ghana, are presented and compared with those of 3383 consecutive new patients seen at the dermatology clinic of The William Harvey Hospital (WHH), Ashford, Kent, UK. RESULTS: The most common conditions in ghana were infections (46.3%; UK, 12%). In the UK, the most common conditions were malignant and premalignant diseases of the skin (22.2%; ghana, 0.5%) and benign tumors (16.8%; ghana, 0.5%). dermatitis was common in both countries (ghana, 18.4%; UK, 16.0%). psoriasis was more common in the UK (6.2%) than in ghana (0.4%). In ghana, fixed drug eruption, mainly due to cotrimoxazole (Septrin), was not rare (27 cases), and complications from cosmetic skin lightening creams were a frequent problem among women (86 cases). No cases of rosacea were found in ghana, but it was not uncommon in the UK (1.6%). CONCLUSIONS: The patterns of skin diseases are different in the two countries. It is hoped that this study may help to catalyze the further development of dermatology services in ghana.- - - - - - - - - - ranking = 1keywords = skin disease (Clic here for more details about this article) |
2/3. carbon dioxide laser surgery for skin disease.Since it was developed in the 1960s, the carbon dioxide (CO2) laser has had an important role in the practice of dermatology. The CO2 laser has some advantages over conventional techniques used in dermatologic surgical treatment. It routinely provides a bloodless surgical field as well as unusual surgical precision. Although the CO2 laser is specifically indicated for certain conditions, in other situations, only marginal benefit may be noted in comparison with standard techniques such as scalpel surgical procedures, dermabrasion, cryosurgery, and electrosurgery. In this article, we briefly review the history and physics of the CO2 laser, its operation, and safety principles and discuss dermatologic conditions that are treated with the CO2 laser. We also describe 8 representative cases from our experience with more than 800 cases of CO2 laser treatment in the practice of dermatology at the Mayo Clinic since 1986.- - - - - - - - - - ranking = 2keywords = skin disease (Clic here for more details about this article) |
3/3. helicobacter pylori immunoproteomes in case reports of rosacea and chronic urticaria.rosacea and chronic urticaria are two common skin disorders existing in idiopathic forms. A role of helicobacter pylori bacterium infection in the aetiopathogenesis of rosacea or chronic urticaria has been suggested although still controversial. The aim of the present study was to establish a relationship between H. pylori infection and rosacea chronic urticaria by means of an immunoproteomic investigation. We analyzed immunoglobulin a (IgA)-, IgG-, and IgE-mediated immune-responses against H. pylori antigens and we identified some bacterial immunoresponsive proteins. A general IgA- and IgE-mediated immune response against antioxidative bacterial proteins was observed. A correlation between the bacterial occurrence and skin diseases pathogenesis is discussed.- - - - - - - - - - ranking = 0.5keywords = skin disease (Clic here for more details about this article) |
