  • Factors predisposing to colorectal cancer in UC patients consist of pancolitis, duration of disease, active disease and its severity. Early UC onset is another independent risk factor. Beside these factors, dysplasia represents the precancerous lesion from which colorectal cancer subsequently arise (Morson, 1962; Morson & Pang, 1967). In fact, 70% of patients with colorectal cancer on UC have dysplasia on colorectal mucosa (Taylor et al., 1992; Connell et al., 1994).

  • Scleroderma often eventuates in development of an expressionless, masklike facies. Morphea is characterized by localized thickening and sclerosis of skin, usually affecting young adults or children. Morphea begins as erythematous or flesh-colored plaques that become sclerotic, develop central hypopigmentation, and demonstrate an erythematous border. In most cases, patients have one or a few lesions, and the disease is termed localized morphea. In some patients, widespread cutaneous lesions may occur, without systemic involvement. This form is called generalized morphea.

  • A biopsy is the removal of pieces of tissue, which are then sent to a lab for testing. A biopsy is most often used to find cancer. Any part of the body, such as the skin, an organ or a lump can be tested. An x-ray, CT scan or ultrasound may be done to locate the biopsy site. A biopsy may be done during surgery. Your doctor will review the results of your biopsy with you at your next visit and talk to you about treatment if needed. If you have any allergies to medicines, foods or other things, tell...

  • Harrison's Internal Medicine Chapter 52. Approach to the Patient with a Skin Disorder APPROACH TO THE PATIENT WITH A SKIN DISORDER: INTRODUCTION The challenge of examining the skin lies in distinguishing normal from abnormal, significant findings from trivial ones, and in integrating pertinent signs and symptoms into an appropriate differential diagnosis. The fact that the largest organ in the body is visible is both an advantage and a disadvantage to those who examine it.

  • Management The entire cutaneous surface, including the scalp and mucous membranes, should be examined in each patient. Bright room illumination is important, and a 7x to 10x hand lens is helpful for evaluating variation in pigment pattern. A history of relevant risk factors should be elicited. Any suspicious lesions should be biopsied, evaluated by a specialist, or recorded by chart and/or photography for follow-up. Examination of the lymph nodes and palpation of the abdominal viscera are part of the staging examination for suspected melanoma.

  • Biopsy Any pigmented cutaneous lesion that has changed in size or shape or has other features suggestive of malignant melanoma is a candidate for biopsy. The recommended technique is an excisional biopsy, as that facilitates pathologic assessment of the lesion, permits accurate measurement of thickness if the lesion is melanoma, and constitutes treatment if the lesion is benign.

  • Some water moves through the skin of mammals by insensitive diffusion. Most of the water, which passes through the skin, however, does so in the form of active sweating. Larger mammals usually sweat to dissipate heat. Among the domestic species, both camels and cattle have adopted this mechanism. A characteristic of the camel is that there is no copious flow of sweat or obvious wetting of the hair. The evaporation takes place at the surface of the skin and not at the extremities of the hair. The latent heat of evaporation is therefore drawn from the skin rather than from...

  • Pink Lesions The cutaneous lesions associated with primary systemic amyloidosis are often pink in color and translucent. Common locations are the face, especially the periorbital and perioral regions, and flexural areas. On biopsy, homogeneous deposits of amyloid are seen in the dermis and in the walls of blood vessels; the latter lead to an increase in vessel wall fragility. As a result, petechiae and purpura develop in clinically normal skin as well as in lesional skin following minor trauma, hence the term pinch purpura.

  • Red Lesions Cutaneous lesions that are red in color have a wide variety of etiologies; in an attempt to simplify their identification, they will be subdivided into papules, papules/plaques, and subcutaneous nodules. Common red papules include arthropod bites and cherry hemangiomas; the latter are small, bright-red, domeshaped papules that represent benign proliferation of capillaries.

  • But risk factors don’t tell us everything. Having a risk factor, or even several risk factors, does not mean that you will get the disease. And some people who get the disease may have few or no known risk factors. Even if a person with basal or squamous cell skin cancer has a risk factor, it is often very hard to know how much that risk factor may have contributed to the cancer. The following are known risk factors for basal cell and squamous cell carcinomas. (These factors don't necessarily apply to other forms of non-melanoma skin cancer, such as...

  • For two main reasons, dermatology is one of the later medical disciplines to use imaging techniques: skin lesions are readily visible to the naked eye or through a magnifying glass, allowing clinical diagnosis with no invasive examination; skin lesions can easily be biopsied or removed for histological study. This approach has therefore remained the basis of clinicopathological diagnosis of skin diseases for a long time. There has also been a third factor.

  • There are several reasons that may explain why the prevalence of heart failure is increasing: ageing of the population, the success in prolonging survival in coronary patients, and the success in postponing coronary events by effective prevention in those patients at high risk or those patients who have already survived a first event (secondary prevention) (Senni et al, 1999). Advances in medical therapy have resulted in improved survival in patients with moderate and severe heart failure, but the prognosis for end-stage heart failure patients still remains poor.

  • The modular producer cell lines present several advantages: they are safer since integration of the vector within the packaging cell line was identified, the duration of the entire development process is much reduced as there is no need for screening and, in addition, production conditions are favorable due to the possibility of pre-adaptation of the master cell line to culture conditions and media. Thus, therapeutic virus production from bench to bedside becomes safer, faster, and cheaper (Coroadinha et al. 2010)....

  • Providers who agreed to participate and scheduled an interview were sent a consent form for the study and a baseline questionnaire (on services provided, type of clinical staff employed, and number of WHP clients served) by email or fax to be returned to the interviewers. The phone interviews lasted approximately 20-30 minutes each, were conducted by 2 researchers in order for one to take notes, and were based upon interview guides developed for PPFA providers and non-PPFA providers.

  • In Hungary, the law provides for a three-tiered territorial system of development councils: at the municipality group, county and county group level. The latter were created to handle the larger decentralised development issues. While the system seemed a logical approach to development at different levels, it has been criticised for inadequate local (particularly: private sector and civil society) representation, lack of coordination among tiers, limited decentralisation of financial resources and a lack of identification of actors with the county groups, which many consider arbitrary.
