...Is Ipilimumab the best solution for the treatment of malignant melanoma? Chloe Walton Malignant melanoma although rare is a form of cancer that without treatment progresses at an extremely fast rate. The development of drugs to try to halt the rapid rate at which malignant melanoma can grow and infect another organ of the body is an on going project by specialists. Dr Alison developed Ipilimumab in 1999 and it was found in the clinical trials that it does, in most cases, exactly what medical professionals have been looking for. However drugs such as ipilimumab come with risks associated with them. This poses the question of whether the benefits outweigh the risks and cost of the drug. Skin and how malignant melanoma develops Skin is the largest organ in our body, responsible for creating a barrier between the outside and our internal organs. The skin is made up of three layers. The first layer is the epidermis, which is made up of mainly keratinocytes; they make micro-layers, which continually grow outwards to compensate for old layers dying and flaking off. Within the epidermis Langerhans cells are contained which alert the immune system to virus’ and bacterium. The next layer is the dermis, which gives the skin its strength due to the elastin and collagen fibres. Also present in the dermis are; blood vessels which allows the skins temperature to be maintained, and nerves which pick up feelings of heat, pain etc. and relay to the brain. The final layer is the...

...SKIN CANCER & TANNING The idea of a “healthy tan” is a myth which must be corrected in order to reduce the increasing incidence of skin cancer in the world. An individual's skin color is determined by their genes and their environment. Our skin can change color in reaction to sun exposure. This is called the "tanning response." When skin absorbs UV radiation, melanin is produced and transferred to the keratinocytes cells within the skin thereby darkening the color of the skin. Melanin in the skin absorbs and scatters UV radiation entering the body and helps protect the skin from adverse reactions to radiation. Thus, the "tanning response" is really a defensive reaction by the body to the presence of damaging radiation, and an effort by the body to protect itself from the harmful affect of ultraviolet A and ultraviolet B (UVA and UVB) rays (“Anatomy”). A tan still remains in the minds of many as socially desirable. Each day we are confronted with images on television and in magazines of golden-brown models and celebrities. In addition, we are the targets of local advertising and promotion of tanning salons. People must understand that a tan is not necessary; and that in addition to the premature aging of the skin, there are serious and possibly deadly consequences from the overexposure of one’s body to UVA and/or UVB rays. The deadly consequence is skin cancer. When people think of cancer they relate to the threat of colon cancer, breast cancer, lung cancer, prostate...

...CASE STUDY Mr. Gergen is a 32 – year – old man who has scheduled an appointment with a dermatologist to have a black spot on his right ear assessed. Mr. Gergen states, “My wife noticed a black circular area on my ear about two weeks ago and she suggested I get it looked at since she did not remember the spot being there before. I know that too much time in the sun in not very good for your skin. I’m a physical education teacher so I am out in the sun a lot, and I admit that I did not always remember to apply sunscreen.” Case Study There is a dark area on Mr. Gergen’s right ear approximately 0.4 cm by 0.4 cm round in size. The color of the surrounding skin is normal. Mr. Gergen says that he noticed the spot about four months earlier but did not think much of it. “I figured it was a mole. Since it did not hurt, I really didn’t give it much thought.” 1. You are the nurse working with the dermatologist. Make a list of questions you could ask regarding the area of concern to help determine if the site on Mr. Gergen’s ear could be melanoma. * Describe your daily hygiene practices? * What skin products are you currently using? * Do you do anything to protect yourself from the sun? * Are you aware of any situation or stressor that changes your skin condition? * Do you think that stress plays a role in your skin condition? * Has your skin condition changed your relationship with others? * Are there any treatment options that...

The fabric that can offer the best rating for ultraviolet protection is the knitted fabric, which is being used for sport T-shirts. Normal T-shirts show a very low rating when it comes to protection against the sun. Not all shirts have the labeling information in regards to ultraviolet protection, but it would be helpful for the consumer to have that information.

...Jason’s Case Study Abstract Jason, a twenty six year old male, is seen in the urgent care clinic with a laceration to his arm. He cut his arm on roof sheeting while at work. While assessing the laceration on Jason’s arm, the nurse notices that he has a sunburn, freckles and moles on his skin. While Jason is still in the urgent care, the patient’s wife calls and asked if the medical staff would assess a mole on her husband. The nurse also educated Jason regarding sunburns, changes in freckles, moles, and lesions. His complexion, hair and eye color puts Jason at a higher risk for cancer and complications of being in the sun. The nurse also reminded Jason to make an appointment to have his family doctor check the laceration on his arm to make sure no infection or complications have developed. Jason’s Case Study After the nurse introduces herself to Jason, she gets his vital signs, height and weight. The nurse or the doctor per facility protocol should cleanse the wound to remove any dirt or debris from the laceration site. The nurse measures the laceration in length and width. The nurse checks the laceration for foreign bodies or debris in his arm. The doctor may order an x-ray of his arm to rule out any foreign bodies that may be in Jason’s arm. Saline gauze should be placed over the laceration site until the doctor comes into the examination room to see the patient. The nurse asks Jason if he has had a tetanus shot in the past five years. Jason should...

...depend on the degree of severity a person has. In the following paper, I will shed lights on the types of skin cancer such as basal cell carcinoma, squamous cell carcinoma, and melanoma. Skin cancer is an abnormal growth of skin cells that usually develops on skin exposed to the sun. Skin cancer can be found in the early stage, which can usually be cured if treated before the spread. Skin cancer begins where we can see it, such as on the face or arms. Some signs may include, growing bumps, changing mole and/or a dry and scaly rough patch. In this paper, I will explain the three major types of skin cancers, such as basal cell carcinoma, squamous cell carcinoma and melanoma. Basal cell carcinoma (BCC) is abnormal, uncontrolled growths that arise in the skin’s basal cells, which line the deepest layer of the epidermis. BCC’s usually appears and look like open sores, red patches, or scars. According to (skincancer.org) “An estimated 2.8 million cases of BCC diagnosed in the United States each year.” Nearly all basal cell carcinoma appear on the body that is mostly exposed to the sun, especially the ears, face, neck, scalp, back and/or shoulders. This disease is common in mostly elderly people, but studies show that people in their twenties and thirties are being treated for this skin cancer. In a few cases, contact with arsenic, exposure to...

...taking skin cancer seriously after knowing its significance. Skin cancer has been a growing problem in the United States and millions of people have suffered from it every year. The three most common skin cancers are Melanoma, Basal cell, and Squamous cell, which can cause bumps, sores, growths, etc. Skin cancer is a deadly disease with many causes, but the advantage is that it can be prevented. Problem/Definition Skin cancer is a disease where cancer (malignant) cells are found on the outer layer of the skin (epidermis). The three types of cells found in the epidermis are squamous cells, basal cells, and melanocytes. These cells in time grow to be cancerous. Thus, the three types of skin cancers are squamous cell, basal cell, and melanoma. Melanoma is the most deadliest and destructive type of cancer. (“Skin Cancer” infotrac.com) The number of people with melanoma has risen in Scotland from 3.5 in 1979 to 10.6 per 100,000 in 1998 for men and 7.0 to 13.1 for women. (Miller 945) Squamous cell and Basal cell skin cancer can kill up to 2,200 people a year in the United States. (Sommerfield SIRS.com) Basal cell, being the most common type of skin cancer, is the cancer that about 75 percent of the people have. (“Skin Cancer “ infotrac.com) Melanoma is mostly seen in older men but ever since tanning came in during the 1970’s, it has increased in women 60 percent around the ages 15-29 over the past three decades.(Sommerfield SIRS.com) “And basal cell and squamous...

...DESCRIPTION: Protein MelanA (Melanoma Antigen), also known as MART-1 (Melanocytic Antigen Recognized by cytotoxic T lymphocytes) is a common biomarker used to identify malignant melanoma (MM) in patients, it falls under the MHC (major histocompatability complex) I class. MART-1 is encoded by the MLANA gene in humans and is present normally on the surface of benign nevi (beauty marks), as well as on melanocytes, the pigment-producing cells of your skin that become abnormal and grow out of control if malignant melanoma has developed. Approximately 76,000 new cases of melanoma are diagnosed annually in the Unites States, which accounts for about 2% of the total skin cancer diagnosis in United States annually; however 75% of skin cancer related deaths are the result of MM which exhibits how devastating this form of cancer is. With early detection of melanoma being correlated highly to improved prognosis of patients, it is necessary to create a point of care device that can measure the presence of MART-1 antigen in peripheral blood as a screening technique during annual examinations and upon identification of suspicious skin lesions Protein melan-A is a protein that in humans is encoded by the MLANA gene . A fragment of the protein, usually consisting of the nine amino acids 27 to 35, is bound byMHC class I complexes which present it to T cells of the immune system. These complexes can be found on the surface of melanoma cells. Decameric peptides (26-35) are...

...past knowledge and straight to intervention. In order to implement these strategies, attitudes towards sun protective behaviours must be challenged (Kristjansson, Ullen & Helgason, 2004). The theory of planned behaviour (TPB; Ajzen, 1991) has often been used to explain the relationship between one’s behaviour to use sun protective measure and their intentions. The TPB facilitates that social factors, perceived barriers/control and attitudes all play a role in deciding whether certain behaviours will be performed (Ajzen, 1991; Hardeman et al, 2002). Many studies have adapted the TPB to predict participant’s intentions to use sun protective measures (Hillhouse et al, 2000; James et al, 2002) and the general norm has validated the TPB as a suitable predictor of intention towards sun-safe behaviours (Araujo-Soares et al, 2012; Bachleda et al,...

MAOI’s have to be withdrawn for a minimum of two weeks prior to initiating therapy with Sinemet (Brenner & Stevens, 2013). Patients who are taking MAOI’s need to consult with their provider prior to starting Sinemet as harmful and life-threatening adverse events could occur when used in combination. Patient with narrow-angle glaucoma or have had a previous hypersensitivity to this drug or a similar compound should not use Sinemet in the treatment of their PD (WebMD, 2015). Additionally, patient with a history of melanoma or undiagnosed skin lesions should refrain from taking Sinemet as it have shown in studies to activate malignant...

...accompanied by the issue of health implications for human. Previous research studies show no evidence of the impacts of mobile phones to human health. New studies suggest that mobile radiation might double the risk of developing cancer on the side of the head used, increase brain activity, can cause damage to nerves around ears and, more importantly, damages the BBB. Also new research shows that biological effects are possible without any warming of tissues which impose of the current radiation exposure levels. KEYWORDS Mobile Radiation, Health Effects INTRODUCTION There are now about 1 Billion mobile phones in use worldwide, and it is expected to reach 1.6B lines by year 2005. In many countries, penetration rates of more than %50 has been reached. At present, there are approximately 4.5 million GSM subscribers in Saudi Arabia and STC has commissioned Ericsson and Nokia to expand its GSM network to 5.5 million lines (~ %20 penetration rate). This wide use of mobile technology have often raise the question about if there are health implications for human. In fact, there are conflicting reports relating to possible health effects from mobile phones and base stations. In April 2000, an independent expert group in UK has issued a report on Mobile phone effects on health based on rigorous assessment of research in this area and show no evidence of the impact of mobile phones to human health. Since then a number of studies has been accomplished. This paper summarizes previous results. Then...

REVIEW OF LITERATURE: Caffeine and alcohol plays a vital role in every daily life of humanity, but which concentrations greatly affect the heart rate of Daphnia magna? So, what are Daphnia magna anyways? caffeine? and alcohol? How do they relate to the real world? Are there any scientific studies that are similar? In this Review of Literature, one must research and discussed the background information based on Daphnia magna, pharmaceuticals drugs: caffeine and alcohol as well as examples of food products, and scientific studies similar to the topic. Daphnia magna are freshwater crustaceans that correlate under Branchipoda with leaf like legs, their bodies are enclosed by uncalcified exterior (carapace) that it mostly components of chitin and polysaccharide making them favorable for laboratory experiments despite of their transparent skin. What’s more, the factors affecting Daphnia magna links pH, temperature, and water. Anywhere in between 6.5 and 9.5 pH are satisfactory, although a high basic pH can harm reproduction though not the health of water fleas. Moving on, Daphnia magna can tolerate 18 to 22° Celsius or in Kevin scale from 337°Kto 345°K...
