Formative research for developing targeted skin cancer prevention programs for children in multiethnic Hawaii. (1/289)
Skin cancer is a significant and increasing public health problem. Improvement in sun protection practices among children holds great promise for prevention, and parents and caregivers play important roles. Health promotion programs are most likely to succeed when based on a systematic planning process including an understanding of current practices, beliefs, social norms and environments. This article describes formative research used to help develop the SunSmart skin cancer prevention program in Hawaii. Group discussions and interviews were conducted with 216 children in grades 1, 2 and 3, 15 parents, and 27 recreation staff. Children's discussion groups took place in intact classrooms. A combination of quantitative and qualitative methods was used. Multiple raters and an iterative process were used to analyze data from survey forms, observer impressions and audio tapes, and to draw the main conclusions. Sun protection practices in all groups were inconsistent, though general awareness about prevention was widespread. Children reported a reluctance to cover up with long pants and sleeves, and wide-brim hats, and did not understand what skin cancer was. Parents and recreation staff were supportive of education and policy supports, to improve both their own and the children's prevention habits. They were enthusiastic about interactive and creative activities. We conclude that targeted skin cancer prevention messages and strategies for Hawaii's children should promote gradual changes, provide environmental supports, and involve parents and recreation staff. Both the findings and procedures have implications for prevention elsewhere. (+info)The use of observational methods for monitoring sun-protection activities in schools. (2/289)
Evaluation of health promotion interventions aimed at behavioural or environmental change involves assessing change that occurs as a result of the program. Direct observational methods can be used for this purpose and this paper describes three such methods that we pilot tested for use in a 5-year intervention study aimed at reducing sun exposure in primary school children. (1) Monitoring 'No hat, no play' policies. This method involved video taping children in selected school play areas during lunch time and analysing the content of the videos to assess the proportion of children wearing various types of hats. (2) Assessing shade provision in the playground. This method involved taking aerial photographs of each school and using them to estimate the proportion of shade in play areas available to children at lunchtime. (3) Shade use. This involved children wearing polysulphone film badges to measure the amount of UV-B exposure they received during one lunch period, relative to the total possible dose registered on index badges. Each method was implemented successfully, and we demonstrated that the video and aerial photography methods produced highly reproducible results and that all three methods were feasible. These three methods will be used in our intervention study to assess longitudinal change in schools' sun-protection policy and practice. (+info)Evaluation of an intervention to reduce sun exposure in children: design and baseline results. (3/289)
The Kidskin Study is a 5-year intervention study (1995-1999) involving 1,776 5- and 6-year-old children attending 33 primary schools in Perth, Western Australia. The aim of the study is to design, implement, and evaluate an intervention to reduce sun exposure in young children. There are three study groups: a control group, a "moderate intervention" group, and a "high intervention" group. The control schools receive the standard Western Australian health education curriculum, while the moderate and high intervention schools receive a specially designed curricular intervention. In addition, children in the high intervention group receive program materials over the summer holidays, when exposure is likely to be highest, and are offered sun-protective swimwear at low cost. The main outcome measure is the number of nevi on the back. Other outcomes include nevi on the chest (boys only), face, and arms, levels of suntanning, degree of freckling, and sun-related behaviors. At baseline, the three groups were similar with respect to nevi and freckling after adjustment for observer and month of observation. Sun exposure was slightly higher in the high intervention group. The groups were also similar with respect to most potential confounders, although they differed with respect to Southern European ethnicity and parental education. (+info)Galectin-7 overexpression is associated with the apoptotic process in UVB-induced sunburn keratinocytes. (4/289)
Galectin-7 is a beta-galactoside binding protein specifically expressed in stratified epithelia and notably in epidermis, but barely detectable in epidermal tumors and absent from squamous carcinoma cell lines. Galectin-7 gene is an early transcriptional target of the tumor suppressor protein P53 [Polyak, K., Xia, Y., Zweier, J., Kinzler, K. & Vogelstein, B. (1997) Nature (London) 389, 300-305]. Because p53 transcriptional activity is increased by genotoxic stresses we have examined the possible effects of ultraviolet radiations (UVB) on galectin-7 expression in epidermal keratinocytes. The amounts of galectin-7 mRNA and protein are increased rapidly after UVB irradiation of epidermal keratinocytes. The increase of galectin-7 is parallel to P53 stabilization. UVB irradiation of skin reconstructed in vitro and of human skin ex vivo demonstrates that galectin-7 overexpression is associated with sunburn/apoptotic keratinocytes. Transfection of a galectin-7 expression vector results in a significant increase in terminal deoxynucleotidyltransferase-mediated UTP end labeling-positive keratinocytes. The present findings demonstrate a keratinocyte-specific protein involved in the UV-induced apoptosis, an essential process in the maintenance of epidermal homeostasis. (+info)Oral contraceptive use and risk of melanoma in premenopausal women. (5/289)
Melanoma has been increasing in white populations. Incidence rates rise steeply in women until about age 50, suggesting oestrogen as a possible risk factor. Oestrogens can increase melanocyte count and melanin content and cause hyperpigmentation of the skin. We examined prospectively the association between oral contraceptive (OC) use and diagnoses of superficial spreading and nodular melanoma among 183,693 premenopausal white women in the Nurses' Health Study (NHS) and the Nurses' Health Study II (NHS II) cohorts. One hundred and forty six cases were confirmed in NHS during follow-up from 1976 to 1994, and 106 cases were confirmed in NHS II from 1989 to 1995. Skin reaction to sun exposure, sunburn history, mole counts, hair colour, family history of melanoma, parity, height and body mass index were also assessed and included in logistic regression models. A significant twofold increase in risk of melanoma (relative risk (RR) = 2.0, 95% confidence interval (CI) 1.2-3.4) was observed among current OC users compared to never users. Risk was further increased among current users with 10 or more years of use (RR = 3.4, 95% CI 1.7-7.0). Risk did not appear elevated among past OC users, even among those with longer durations of use, and risk did not decline linearly with time since last use. In conclusion, risk of premenopausal melanoma may be increased among women who are current OC users, particularly among those with longer durations of use. Further research is needed to determine whether low-dose oestrogen pills in particular are associated with an increase in risk and to describe possible interactions between OC use and sun exposure or other risk factors for melanoma. (+info)Evaluation of apoptotic cells induced by ultraviolet light B radiation in epidermal sheets stained by the TUNEL technique. (6/289)
Two major components of epidermal cells, keratinocytes and Langerhans cells, are injured by ultraviolet light B radiation, resulting in sunburn cell (apoptotic cell) formation, impaired function, and a reduced number of Langerhans cells. Quantitative analysis of Langerhans cell damage is usually performed using epidermal sheets, whereas that of keratinocytes has been performed by counting the number of sunburn cells in vertical tissue sections. In this study we assessed the influences of ultraviolet light B radiation on epidermal cells by apoptotic cell formation, using murine epidermal sheets stained by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling technique. Ten to 75 mJ per cm2 of ultraviolet light B radiation induced apoptotic cells in abdominal skin of C3H mice. The cells were induced in 6 h after 50 mJ per cm2 of ultraviolet light B irradiation with the peak in number in 24 h, 18.8 +/- 5.0 per mm2 and 97.7 +/- 7.4 per mm2, respectively. One week later, the apoptotic cells were not visualized. As C3H/He, BALB/C, and C57BL/6 mice showed almost the same frequency of apoptosis in epidermal sheets from 50 mJ per cm2 ultraviolet light B-irradiated skin, the induction of the cells by ultraviolet light B radiation did not depend on the genetic trait of the mouse. Xeroderma pigmentosum type A gene-deficient mice, however, showed a greater induction of apoptotic cells (216.9 +/- 25.2 per mm2) by ultraviolet light B radiation than xeroderma pigmentosum type A wild-type mice (89.5 +/- 13.6 per mm2) and conventional mice. Pretreatment with a SPF 60 sunscreen agent was quite effective in reducing the induction of apoptotic cells. Using confocal laser scanning microscopy and double staining, 1.5 +/- 2.7% of apoptotic cells were Ia-positive cells in 24 h after 50 mJ per cm2 of ultraviolet light B radiation. Apoptotic Ia-positive cells were not observed 48 h after the radiation. On the other hand, no apoptotic dendritic epidermal T cells were observed in up to 75 mJ per cm2 of ultraviolet light B radiated skin. Thus, nearly all apoptotic cells were keratinocytes, and Langerhans cells and dendritic epidermal T cells appeared resistant to ultraviolet light B-induced apoptosis. Compared with the assessment in vertical tissue sections, the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling technique with epidermal sheets appeared to be a more physiologically relevant method for quantitative evaluation of apoptotic epidermal cells induced by ultraviolet light B radiation. (+info)Temporal events in skin injury and the early adaptive responses in ultraviolet-irradiated mouse skin. (7/289)
We examined the effects of ultraviolet (UV) radiation on the time course for induction of sunburn (apoptotic) cells and expression of proteins known to be associated with growth arrest and apoptosis in SKH-hr1 mouse skin. Mice were irradiated with a single dose (2.5 kJ/m(2)) of UV from Kodacel-filtered (290-400 nm) FS40 sunlamps and the skin tissues were analyzed at various times after irradiation for the presence of apoptotic cells and expression of p53, p21(Waf-1/Cip1), bcl-2, bax, and proliferating cell nuclear antigen. The results indicated that p53 expression was induced early in the epidermis, reaching maximum levels 12 hours after irradiaton, and p21(Waf-1/Cip1) expression in the epidermis peaked at 24 hours after irradiation. In contrast, UV radiation induced high levels of bax at 24 to 72 hours after irradiation with a concomitant decrease in bcl-2 expression. Coinciding with these changes, apoptotic cells began to appear 6 hours after irradiation and reached a maximum at 24 hours after irradiation. Interestingly, proliferating cell nuclear antigen expression, which was initially confined to the basal layer, became dispersed throughout the basal and suprabasal layers of the skin at 48 hours and paralleled marked hyperplasia. These results suggest that UV irradiation of mouse skin induces apoptosis mediated by the p53/p21/bax/bcl-2 pathway and that the dead cells are replaced by hyperproliferative cells, leading to epidermal hyperplasia. This implies that UV-induced apoptosis and hyperplasia are closely linked and tightly regulated and that dysregulation of these two events may lead to skin cancer development. (+info)Sensitivity to sunburn is associated with susceptibility to ultraviolet radiation-induced suppression of cutaneous cell-mediated immunity. (8/289)
Skin cancer incidence is highest in white-skinned people. Within this group, skin types I/II (sun sensitive/tan poorly) are at greater risk than skin types III/IV (sun tolerant/tan well). Studies in mice demonstrate that ultraviolet radiation (UVR)-induced suppression of cell-mediated immune function plays an important role in the development of skin cancer and induces a susceptibility to infectious disease. A similar role is suspected in humans, but we lack quantitative human data to make risk assessments of ambient solar exposure on human health. This study demonstrates that ambient levels of solar UVR, typically experienced within 1 h of exposure to noonday summer sunlight, can suppress contact hypersensitivity (CHS) responses in healthy white-skinned humans in vivo (n = 93). There was a linear relationship between increase in erythema and suppression of CHS (P < 0.001), and a moderate sunburn (two minimal erythema doses [2 MED]) was sufficient to suppress CHS in all volunteers by 93%. However, a single suberythemal exposure of either 0.25 or 0.5 MED suppressed CHS responses by 50 and 80%, respectively, in skin types I/II, whereas 1 MED only suppressed CHS by 40% in skin types III/IV. The two- to threefold greater sensitivity of skin types I/II for a given level of sunburn may play a role in their greater sensitivity to skin cancer. (+info)Sunburn is a cutaneous condition characterized by redness, pain, and sometimes swelling of the skin caused by overexposure to ultraviolet (UV) radiation from the sun or other sources such as tanning beds. The skin may also blister and peel in severe cases. Sunburn is essentially a burn to the skin that can have both immediate and long-term consequences, including increased aging of the skin and an increased risk of skin cancer. It is important to protect the skin from excessive sun exposure by using sunscreen, wearing protective clothing, and seeking shade during peak sunlight hours.
Sunscreening agents, also known as sunscreens or sunblocks, are substances that protect the skin from the harmful effects of ultraviolet (UV) radiation from the sun. They work by absorbing, reflecting, or scattering UV radiation, preventing it from reaching the skin and causing damage such as sunburn, premature aging, and skin cancer.
Sunscreening agents can be chemical or physical. Chemical sunscreens contain organic compounds that absorb UV radiation and convert it into heat, which is then released from the skin. Examples of chemical sunscreens include oxybenzone, avobenzone, octinoxate, and homosalate.
Physical sunscreens, on the other hand, contain inorganic compounds that reflect or scatter UV radiation away from the skin. The most common physical sunscreen agents are zinc oxide and titanium dioxide.
Sunscreening agents are usually formulated into creams, lotions, gels, sprays, or sticks and are applied to the skin before sun exposure. They should be reapplied every two hours or after swimming, sweating, or toweling off to ensure continued protection. It is recommended to use a broad-spectrum sunscreen with an SPF (Sun Protection Factor) of at least 30, which blocks both UVA and UVB radiation.
I'm sorry for any confusion, but "sunlight" is not a term with a specific medical definition. However, sunlight does have various implications in the field of medicine. It is the light that comes from the sun, which is a star at the center of our solar system. Sunlight is essential for the production of vitamin D in humans, and it can also have effects on mood and sleep patterns due to its influence on circadian rhythms.
In a medical context, sunlight is often discussed in relation to its potential health benefits and risks. For instance, moderate sun exposure can help increase vitamin D levels, which are important for bone health, immune function, and other bodily processes. However, excessive sun exposure can lead to harmful effects, such as sunburn, premature skin aging, and an increased risk of skin cancer.
It's essential to balance the benefits and risks of sunlight exposure by practicing safe sun habits, such as wearing protective clothing, using a broad-spectrum sunscreen with an SPF of at least 30, seeking shade during peak sunlight hours, and avoiding intentional tanning.
Skin pigmentation is the coloration of the skin that is primarily determined by two types of melanin pigments, eumelanin and pheomelanin. These pigments are produced by melanocytes, which are specialized cells located in the epidermis. Eumelanin is responsible for brown or black coloration, while pheomelanin produces a red or yellow hue.
The amount and distribution of melanin in the skin can vary depending on genetic factors, age, sun exposure, and various other influences. Increased production of melanin in response to UV radiation from the sun helps protect the skin from damage, leading to darkening or tanning of the skin. However, excessive sun exposure can also cause irregular pigmentation, such as sunspots or freckles.
Abnormalities in skin pigmentation can result from various medical conditions, including albinism (lack of melanin production), vitiligo (loss of melanocytes leading to white patches), and melasma (excessive pigmentation often caused by hormonal changes). These conditions may require medical treatment to manage or improve the pigmentation issues.
I'm happy to help, but I must clarify that while I can provide information based on the data I have up to 2021, I don't have real-time capabilities. Therefore, I can't provide current medical definitions or the latest research findings.
As for your question, sunbathing is not a medical term per se, but it is a practice related to dermatology and health. Sunbathing generally refers to the act of exposing one's skin to sunlight, usually with the intention of darkening the complexion due to tanning or for perceived benefits from ultraviolet (UV) radiation exposure.
However, it is essential to note that excessive sunbathing can lead to various health issues, including premature skin aging, eye damage, and an increased risk of skin cancer due to UV radiation exposure. Therefore, dermatologists generally advise practicing sun safety measures, such as wearing protective clothing, using a broad-spectrum sunscreen with an SPF of at least 30, seeking shade during peak sunlight hours, and avoiding intentional tanning.
Heliotherapy is not a common term used in current medical practice, but it does have a historical significance. It refers to the use of natural sunlight or artificial ultraviolet light as a therapeutic tool. This was particularly popular in the late 19th and early 20th centuries for conditions like tuberculosis, rickets, and various skin diseases. However, its use has significantly decreased with the advent of modern pharmacological treatments and a better understanding of the potential risks associated with overexposure to sunlight, such as skin cancer. Please consult with a healthcare professional for more information.
Skin neoplasms refer to abnormal growths or tumors in the skin that can be benign (non-cancerous) or malignant (cancerous). They result from uncontrolled multiplication of skin cells, which can form various types of lesions. These growths may appear as lumps, bumps, sores, patches, or discolored areas on the skin.
Benign skin neoplasms include conditions such as moles, warts, and seborrheic keratoses, while malignant skin neoplasms are primarily classified into melanoma, squamous cell carcinoma, and basal cell carcinoma. These three types of cancerous skin growths are collectively known as non-melanoma skin cancers (NMSCs). Melanoma is the most aggressive and dangerous form of skin cancer, while NMSCs tend to be less invasive but more common.
It's essential to monitor any changes in existing skin lesions or the appearance of new growths and consult a healthcare professional for proper evaluation and treatment if needed.
Erythema is a term used in medicine to describe redness of the skin, which occurs as a result of increased blood flow in the superficial capillaries. This redness can be caused by various factors such as inflammation, infection, trauma, or exposure to heat, cold, or ultraviolet radiation. In some cases, erythema may also be accompanied by other symptoms such as swelling, warmth, pain, or itching. It is a common finding in many medical conditions and can vary in severity from mild to severe.
Protective clothing refers to specialized garments worn by healthcare professionals, first responders, or workers in various industries to protect themselves from potential hazards that could cause harm to their bodies. These hazards may include biological agents (such as viruses or bacteria), chemicals, radiological particles, physical injuries, or extreme temperatures.
Examples of protective clothing include:
1. Medical/isolation gowns: Fluid-resistant garments worn by healthcare workers during medical procedures to protect against the spread of infectious diseases.
2. Lab coats: Protective garments typically worn in laboratories to shield the wearer's skin and clothing from potential chemical or biological exposure.
3. Coveralls: One-piece garments that cover the entire body, often used in industries with high exposure risks, such as chemical manufacturing or construction.
4. Gloves: Protective hand coverings made of materials like latex, nitrile, or vinyl, which prevent direct contact with hazardous substances.
5. Face masks and respirators: Devices worn over the nose and mouth to filter out airborne particles, protecting the wearer from inhaling harmful substances.
6. Helmets and face shields: Protective headgear used in various industries to prevent physical injuries from falling objects or impact.
7. Fire-resistant clothing: Specialized garments worn by firefighters and those working with high temperatures or open flames to protect against burns and heat exposure.
The choice of protective clothing depends on the specific hazards present in the work environment, as well as the nature and duration of potential exposures. Proper use, maintenance, and training are essential for ensuring the effectiveness of protective clothing in minimizing risks and maintaining worker safety.
According to the medical definition, ultraviolet (UV) rays are invisible radiations that fall in the range of the electromagnetic spectrum between 100-400 nanometers. UV rays are further divided into three categories: UVA (320-400 nm), UVB (280-320 nm), and UVC (100-280 nm).
UV rays have various sources, including the sun and artificial sources like tanning beds. Prolonged exposure to UV rays can cause damage to the skin, leading to premature aging, eye damage, and an increased risk of skin cancer. UVA rays penetrate deeper into the skin and are associated with skin aging, while UVB rays primarily affect the outer layer of the skin and are linked to sunburns and skin cancer. UVC rays are the most harmful but fortunately, they are absorbed by the Earth's atmosphere and do not reach the surface.
Healthcare professionals recommend limiting exposure to UV rays, wearing protective clothing, using broad-spectrum sunscreen with an SPF of at least 30, and avoiding tanning beds to reduce the risk of UV-related health problems.
Eye color is a characteristic determined by variations in a person's genes. The color of the eyes depends on the amount and type of pigment called melanin found in the eye's iris.
There are three main types of eye colors: brown, blue, and green. Brown eyes have the most melanin, while blue eyes have the least. Green eyes have a moderate amount of melanin combined with a golden tint that reflects light to give them their unique color.
Eye color is a polygenic trait, which means it is influenced by multiple genes. The two main genes responsible for eye color are OCA2 and HERC2, both located on chromosome 15. These genes control the production, transport, and storage of melanin in the iris.
It's important to note that eye color can change during infancy and early childhood due to the development of melanin in the iris. Additionally, some medications or medical conditions may also cause changes in eye color over time.
A nevus, also known as a mole, is a benign growth or mark on the skin that is usually brown or black. It can be raised or flat and can appear anywhere on the body. Nevi are made up of cells called melanocytes, which produce the pigment melanin. Most nevi develop in childhood or adolescence, but they can also appear later in life. Some people have many nevi, while others have few or none.
There are several types of nevi, including:
* Common nevi: These are the most common type of mole and are usually small, round, and brown or black. They can be flat or raised and can appear anywhere on the body.
* Atypical nevi: These moles are larger than common nevi and have irregular borders and color. They may be flat or raised and can appear anywhere on the body, but are most commonly found on the trunk and extremities. Atypical nevi are more likely to develop into melanoma, a type of skin cancer, than common nevi.
* Congenital nevi: These moles are present at birth and can vary in size from small to large. They are more likely to develop into melanoma than moles that develop later in life.
* Spitz nevi: These are rare, benign growths that typically appear in children and adolescents. They are usually pink or red and dome-shaped.
It is important to monitor nevi for changes in size, shape, color, and texture, as these can be signs of melanoma. If you notice any changes in a mole, or if you have a new mole that is unusual or bleeding, it is important to see a healthcare provider for further evaluation.
I'm sorry for any confusion, but "hair color" is not a term that has a medical definition in the same way that a term like "myocardial infarction" (heart attack) does. Hair color can be described in various ways, such as being a natural hair color (like blonde, brunette, red, or black) or describing a change in hair color due to factors like aging (gray or white hairs) or hair dye usage.
However, it's worth noting that changes in hair color can sometimes be associated with certain medical conditions. For example, premature graying of the hair before the age of 30 can be a feature of certain genetic disorders or vitamin B12 deficiency. Similarly, some skin conditions like alopecia areata or vitiligo can cause patchy changes in hair color. But these associations don't provide a medical definition for 'hair color'.
A nevus pigmentosus, also known as a pigmented mole or melanocytic nevus, is a benign proliferation of melanocytes, the pigment-producing cells in the skin. These lesions typically appear as well-circumscribed, brown to black macules or papules. They can vary in size and shape and may be flat or raised. Most nevi are harmless and do not require treatment; however, some may undergo malignant transformation into melanoma, a potentially life-threatening skin cancer. Regular self-skin examinations and professional skin checks are recommended to monitor for changes in nevi that may indicate malignancy.
Keratosis, in general, refers to a skin condition characterized by the abnormal growth or development of keratin, a protein that forms part of the outer layer of the skin (epidermis). There are several types of keratosis, including:
1. Seborrheic Keratosis: benign, often pigmented, rough, and scaly growths that can appear anywhere on the body. They tend to increase in number with age.
2. Actinic Keratosis: rough, scaly patches or spots on the skin that are caused by long-term exposure to sunlight or artificial UV light. These have the potential to develop into squamous cell carcinoma, a type of skin cancer.
3. Solar Keratosis: another term for actinic keratosis, as it is primarily caused by sun damage.
4. Keratosis Pilaris: a common condition where small, rough bumps appear on the skin, often on the arms, thighs, or cheeks. These are caused by excess keratin blocking hair follicles.
5. Follicular Keratosis: a disorder characterized by the formation of horny plugs within the hair follicles, leading to rough, sandpaper-like bumps on the skin.
6. Intraepidermal Keratosis: a term used to describe the abnormal accumulation of keratin in the epidermis, which can lead to various skin conditions.
It's important to consult with a healthcare professional or dermatologist for proper diagnosis and treatment if you suspect having any form of keratosis.
I'm not a doctor, but I can provide some information on the topic. "Mud therapy," also known as pelotherapy, is a type of alternative or complementary medicine that involves the use of mud or clay as a treatment for various health conditions. The theory behind it is that the minerals and other properties found in certain types of mud can have therapeutic effects when applied to the body.
Mud therapy is often used in spas and wellness centers for relaxation, stress relief, and skin care. It's also used in some medical contexts, such as physical therapy and rehabilitation, where mud packs or mud baths may be applied to reduce pain and inflammation in muscles and joints. Some proponents of mud therapy also claim that it can help boost the immune system, detoxify the body, and improve circulation.
It's important to note that while some people report benefits from mud therapy, there is limited scientific evidence to support many of its claimed health benefits. As with any alternative therapy, it's always a good idea to talk to your doctor before trying mud therapy, especially if you have any underlying medical conditions or take medication.
Radiation-induced neoplasms are a type of cancer or tumor that develops as a result of exposure to ionizing radiation. Ionizing radiation is radiation with enough energy to remove tightly bound electrons from atoms or molecules, leading to the formation of ions. This type of radiation can damage DNA and other cellular structures, which can lead to mutations and uncontrolled cell growth, resulting in the development of a neoplasm.
Radiation-induced neoplasms can occur after exposure to high levels of ionizing radiation, such as that received during radiation therapy for cancer treatment or from nuclear accidents. The risk of developing a radiation-induced neoplasm depends on several factors, including the dose and duration of radiation exposure, the type of radiation, and the individual's genetic susceptibility to radiation-induced damage.
Radiation-induced neoplasms can take many years to develop after initial exposure to ionizing radiation, and they often occur at the site of previous radiation therapy. Common types of radiation-induced neoplasms include sarcomas, carcinomas, and thyroid cancer. It is important to note that while ionizing radiation can increase the risk of developing cancer, the overall risk is still relatively low, especially when compared to other well-established cancer risk factors such as smoking and exposure to certain chemicals.
Carcinoma, basal cell is a type of skin cancer that arises from the basal cells, which are located in the lower part of the epidermis (the outermost layer of the skin). It is also known as basal cell carcinoma (BCC) and is the most common form of skin cancer.
BCC typically appears as a small, shiny, pearly bump or nodule on the skin, often in sun-exposed areas such as the face, ears, neck, hands, and arms. It may also appear as a scar-like area that is white, yellow, or waxy. BCCs are usually slow growing and rarely spread (metastasize) to other parts of the body. However, they can be locally invasive and destroy surrounding tissue if left untreated.
The exact cause of BCC is not known, but it is thought to be related to a combination of genetic and environmental factors, including exposure to ultraviolet (UV) radiation from the sun or tanning beds. People with fair skin, light hair, and blue or green eyes are at increased risk of developing BCC.
Treatment for BCC typically involves surgical removal of the tumor, along with a margin of healthy tissue. Other treatment options may include radiation therapy, topical chemotherapy, or photodynamic therapy. Prevention measures include protecting your skin from UV radiation by wearing protective clothing, using sunscreen, and avoiding tanning beds.
Melanoma is defined as a type of cancer that develops from the pigment-containing cells known as melanocytes. It typically occurs in the skin but can rarely occur in other parts of the body, including the eyes and internal organs. Melanoma is characterized by the uncontrolled growth and multiplication of melanocytes, which can form malignant tumors that invade and destroy surrounding tissue.
Melanoma is often caused by exposure to ultraviolet (UV) radiation from the sun or tanning beds, but it can also occur in areas of the body not exposed to the sun. It is more likely to develop in people with fair skin, light hair, and blue or green eyes, but it can affect anyone, regardless of their skin type.
Melanoma can be treated effectively if detected early, but if left untreated, it can spread to other parts of the body and become life-threatening. Treatment options for melanoma include surgery, radiation therapy, chemotherapy, immunotherapy, and targeted therapy, depending on the stage and location of the cancer. Regular skin examinations and self-checks are recommended to detect any changes or abnormalities in moles or other pigmented lesions that may indicate melanoma.
Cosmetics are defined in the medical field as products that are intended to be applied or introduced to the human body for cleansing, beautifying, promoting attractiveness, and altering the appearance. According to the U.S. Food and Drug Administration (FDA), cosmetics include skin creams, lotions, makeup, perfumes, lipsticks, fingernail polishes, eye and facial makeup preparations, shampoos, permanent waves, hair colors, toothpastes, and deodorants, as well as any material intended for use as a component of a cosmetic product.
It's important to note that the FDA classifies cosmetics and drugs differently. Drugs are defined as products that are intended to diagnose, cure, mitigate, treat, or prevent disease, and/or affect the structure or function of the body. Some products, such as anti-dandruff shampoos or toothpastes with fluoride, can be considered both a cosmetic and a drug because they have both cleansing and therapeutic properties. These types of products are subject to regulation by both the FDA's Office of Cosmetics and Colors and its Center for Drug Evaluation and Research.
Cosmetics must not be adulterated or misbranded, meaning that they must be safe for use under labeled or customary conditions, properly packaged and labeled, and not contain any harmful ingredients. However, the FDA does not have the authority to approve cosmetic products before they go on the market, with the exception of color additives. Manufacturers are responsible for ensuring that their products are safe and properly labeled.
"Hairless mice" is a term used to describe strains of laboratory mice that lack a functional fur coat. This condition is also known as "nude mice." The hairlessness in these mice is caused by a genetic mutation that results in the absence or underdevelopment of hair follicles and a weakened immune system.
Hairless mice are often used in scientific research because their impaired immune systems make them more susceptible to certain diseases, allowing researchers to study the progression and treatment of those conditions in a controlled environment. Additionally, their lack of fur makes it easier to observe and monitor skin conditions and wounds. These mice are also used as models for human diseases such as cancer, AIDS, and autoimmune disorders.
In medical terms, the skin is the largest organ of the human body. It consists of two main layers: the epidermis (outer layer) and dermis (inner layer), as well as accessory structures like hair follicles, sweat glands, and oil glands. The skin plays a crucial role in protecting us from external factors such as bacteria, viruses, and environmental hazards, while also regulating body temperature and enabling the sense of touch.
I'm not able to provide a medical definition for "swimming pools" as it is not a term that is typically used in the medical field. However, swimming pools are bodies of water designed for swimming and other recreational activities. They can be found in various settings such as residential homes, community centers, hotels, and fitness clubs. Swimming pools can contain either chlorinated or saltwater and should be properly maintained to prevent the growth of harmful bacteria and algae that can cause illnesses.
If you have any medical concerns related to swimming or using swimming pools, I would recommend consulting with a healthcare professional for advice tailored to your specific situation.
A suntan, also known as sun tan, is not a formal medical term, but it refers to the darkening of the skin due to exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. This darkening occurs when the UV radiation triggers an increase in melanin production in the skin's outer layer (epidermis). Melanin is a pigment that helps protect the skin from further UV damage by absorbing and scattering the radiation.
It is important to note that while a suntan may give the appearance of a temporary "healthy glow," it actually represents skin damage. Prolonged or excessive exposure to UV radiation can lead to premature aging, wrinkles, sunburn, and an increased risk of skin cancer. The American Academy of Dermatology recommends protecting your skin from the sun by seeking shade, wearing protective clothing, hats, and sunglasses, and applying a broad-spectrum, water-resistant sunscreen with an SPF of 30 or higher to all exposed skin.
I'm not aware of a specific medical definition for "bathing beaches." The term "bathing beach" is commonly used to refer to a public shoreline area, such as on a lake or ocean, that is designated for swimming or bathing. However, in a public health context, the term might be used to describe a body of water where people are more likely to swim and therefore where water quality and safety need to be closely monitored.
Public health agencies may test the water at bathing beaches for contaminants such as bacteria or chemicals that could pose a risk to swimmers' health. If high levels of these contaminants are detected, the agency may issue an advisory or closure of the beach to protect public health. For example, the U.S. Environmental Protection Agency (EPA) sets standards for water quality at bathing beaches and provides guidance to states and localities on monitoring and managing beach water quality.
Skin aging, also known as cutaneous aging, is a complex and multifactorial process characterized by various visible changes in the skin's appearance and function. It can be divided into two main types: intrinsic (chronological or natural) aging and extrinsic (environmental) aging.
Intrinsic aging is a genetically determined and time-dependent process that results from internal factors such as cellular metabolism, hormonal changes, and genetic predisposition. The primary features of intrinsic aging include gradual thinning of the epidermis and dermis, decreased collagen and elastin production, reduced skin cell turnover, and impaired wound healing. Clinically, these changes present as fine wrinkles, dryness, loss of elasticity, and increased fragility of the skin.
Extrinsic aging, on the other hand, is caused by external factors such as ultraviolet (UV) radiation, pollution, smoking, alcohol consumption, and poor nutrition. Exposure to these environmental elements leads to oxidative stress, inflammation, and DNA damage, which accelerate the aging process. The main features of extrinsic aging are coarse wrinkles, pigmentary changes (e.g., age spots, melasma), irregular texture, skin laxity, and increased risk of developing skin cancers.
It is important to note that intrinsic and extrinsic aging processes often interact and contribute to the overall appearance of aged skin. A comprehensive approach to skincare should address both types of aging to maintain healthy and youthful-looking skin.
Seborrheic dermatitis is a common, inflammatory skin condition that mainly affects the scalp, face, and upper part of the body. It causes skin irritation, flaking, and redness, often in areas where the skin is oily or greasy. The exact cause of seborrheic dermatitis is not fully understood, but it appears to be related to a combination of genetic, environmental, and microbial factors.
The symptoms of seborrheic dermatitis can vary in severity and may include:
* Greasy or flaky scales on the scalp, eyebrows, eyelashes, ears, or beard
* Redness and inflammation of the skin
* Itching, burning, or stinging sensations
* Yellow or white crusty patches on the scalp or other affected areas
* Hair loss (in severe cases)
Seborrheic dermatitis is a chronic condition that tends to flare up and then subside over time. While there is no cure for seborrheic dermatitis, various treatments can help manage the symptoms and prevent complications. These may include medicated shampoos, topical creams or ointments, and lifestyle changes such as stress reduction and avoiding triggers that worsen symptoms.
It is important to note that seborrheic dermatitis should not be confused with other skin conditions, such as psoriasis or eczema, which may have similar symptoms. A healthcare professional can provide a proper diagnosis and recommend appropriate treatment options based on the individual's specific needs.
A dose-response relationship in radiation refers to the correlation between the amount of radiation exposure (dose) and the biological response or adverse health effects observed in exposed individuals. As the level of radiation dose increases, the severity and frequency of the adverse health effects also tend to increase. This relationship is crucial in understanding the risks associated with various levels of radiation exposure and helps inform radiation protection standards and guidelines.
The effects of ionizing radiation can be categorized into two types: deterministic and stochastic. Deterministic effects have a threshold dose below which no effect is observed, and above this threshold, the severity of the effect increases with higher doses. Examples include radiation-induced cataracts or radiation dermatitis. Stochastic effects, on the other hand, do not have a clear threshold and are based on probability; as the dose increases, so does the likelihood of the adverse health effect occurring, such as an increased risk of cancer.
Understanding the dose-response relationship in radiation exposure is essential for setting limits on occupational and public exposure to ionizing radiation, optimizing radiation protection practices, and developing effective medical countermeasures in case of radiation emergencies.
"Rescue work" is not a term that has a specific medical definition. However, in a broader context, it generally refers to the actions and procedures taken to preserve life, prevent further harm, or provide emergency care to individuals who are in a situation of distress or danger, which may include natural disasters, accidents, or medical emergencies.
Healthcare professionals, including physicians, nurses, and emergency responders, may be involved in rescue work during mass casualty events, search and rescue missions, or other disaster response situations. The goal of rescue work is to stabilize patients and ensure their safety until they can receive further medical attention.
