Dermatology By Brennan Barger

Dermatology is fascinating because it deals with the largest organ in a living organism.
Approximately 15-20% of the average adult's total body weight is skin. The skin is filled with billions of cells, thousands of sensory points, sweat glands, sebaceous glands -- each doing it’s part to keep the skin healthy. A dermatologist takes care of diseases, in the widest sense, and some cosmetic problems of the skin, scalp, hair, and nails. There are several different subspecialties in dermatology. They are: * Cosmetic Dermatology * Dermatopathology * Immunodermatology * Mohs Surgery * Pediatric Dermatology * Teledermatology Cosmetic dermatology deals generally with laser surgeries, botox and fillers. Some derm- atologists deal specifically with face lifts, liposuction, and blepharoplasty. Many dermatologists limit their work to minimally evasive cosmetic procedures Dermatopathology specializes in the pathology of the skin. Usually a dermatologist or pathologist will complete one year of dermatopathology fellowship. This usually includes six months of general pathology, and six months of dermatopathology. Alumni of both specialties may qualify as dermatopathologists. Immunodermatology deals specifically with treating immune mediated skin diseases and disorders. Lupus, bullous pemphigoid, and pemphigus vulgaris are just a few of the ailments doctors in this field may treat. Mohs surgery, also known as chemosurgery, created by a general surgeon, Dr. Frederic E.
Mohs, is a microscopically controlled surgery used to treat common types of skin cancer.
Mohs surgery allows the surgeon to remove a skin cancer with very narrow surgical margin and has a high cure rate. The surgery is done in 4 steps. * Surgical removal of tissue (Surgical Oncology) * Mapping the piece of tissue, freezing and cutting the tissue between 5 and 10 micrometers using a cryostat, and staining with hematoxylin and eosin * Interpretation of microscope slides (Pathology) * Reconstruction of the surgical defect
There is some controversy about this type of surgery. There are some in the medical community who say that this type of surgery is no better than standard excision procedures. The pediatric dermatology field encompasses the complex diseases of the neonates, such as epidermolysis bullosa and Hailey-Hailey disease, blistering disorders, to the everyday bacterial, fungal and viral infections such as diaper rashes and baby acne, also called acne neonatorum. Teledermatology is a form of dermatology where telecommunication technologies come in handy. They are used to exchange medical information via all kinds of media (audio, visual and also data communication, but typically photos of dermatologic conditions) usually made by non-dermatologists for evaluation off-site by dermatologist . This type of specialty is used to obtain second opinions from the experts across the country or to use as follow up for individuals with chronic skin conditions. Some of the therapies that dermatologists provides can be done in office. Some are as simple as filler injections for fine lines to more complex liposuction procedures that must be done in a surgical setting. The first work on dermatology, called de morbis cutaneis ("On the diseases of the skin") was done by Geronimo Mercuriali, an Italian doctor, in 1572. Other doctors, such as Dr. Alfred
Hardy, Dr. Howard Franklin Damon and Dr. George Henry Fox, produced important photographic identification of dermatological diseases in the late 1800s. Since then, dermatology has grown into a thriving area of medicine all over the world. Dermatologys scientific basis was established in the mid-19th century by Ferdinand von Hebra (1816 – 1880), whose approach was based on microscopic examination of skin lesions. Dermatology developed as a subspecialty of internal medicine in the 18th century. It was initially combined with the diagnosis and treatment of venereal diseases, because syphilis was an important possible diagnosis in any skin rash.

Trouble with Advertising

...Trouble with Advertising This week’s assignment has been a real eye opener when you start to look at advertisements with a more critical and informed perspective. When a person starts to listen to the questions and look behind the factual statements made then we can see where they are trying to steer us so we will buy their product or use what they are selling. All too often the advertisers pray on the ignorance of the consumers and will miss lead them with misdirection and deception. With the knowledge we have gained these past few week we can analyze what we are surrounded by and make a more informed decision in our daily purchases. I will look at the fourteenth question, “How often do you run red lights?” (Bluman, 2011) This is an illustration of Asking a Biased question. Our text states that, “By asking a question in a certain way, the researcher can lead the respondents to answer the question the way the researcher wants them to.” (Bluman, 2011) This question asks the person if they have committed a crime so they are already on the defensive from the way the question is phased. I would hope that there are no good reasons to run a red light unless there is a life or death situation which would then put other people at risk when you run the red light. When the question puts you on the defensive you will be hard pressed to give a truthful answer which then invalidates the survey. Next I will examine the sixth question. In an ad for moisturizing lotion, the following...

...nurse practitioner in dermatology. To achieve this, I plan to first obtain my doctorate degree as a family nurse practitioner, then move into the dermatology specialty. As Currie, Chiarella, and Buckley explain, nurse practitioners are registered nurses who have been trained to “perform at an advanced level of assessment and clinical decision-making” (2013). Continuing my education in nursing is important to me, as it yields an array of new opportunities and greater responsibilities. Nurse practitioners differ from registered nurses in that they are able to prescribe medication, provide orders, and refer patients to other healthcare professionals (Currie, Chiarella, & Buckley, 2013).

Accutane

...Accutane Used in Dermatology and Its Side Effects December 12, 2012 Abstract Accutane is a prescription drug used in the treatment of moderate to severe acne. The medication is classified as a retinoid, which is a part of a group of chemical compounds chemically related to Vitamin A. Accutane is also known by its generic name Isotretinoin. The medication is prescribed when there has been significant scarring early on in the disease and is primarily used for severe acne issues. It works by altering DNA transcription, altering the size and output of sebaceous glands, and decreasing the amount of bacteria in the sebaceous glands and on the skin surface[Heather Brannon, MD; 2005]. Accutane’s side effects have proven to be more damaging than the drugs supposed skin improvement causing it to be banned by the FDA. Accutane Used in Dermatology and Its Side Effects Accutane is a medication prescribed to individuals that suffer from severe acne issues that have failed to respond to full courses of other medications. It is prescribed in dosages of 10mg, 20mg, and 40mg to be taken orally for a course of sixteen to forty weeks once or twice a day [Drugs.com, 2012]. The dosage of the drug given is determined by body weight, age, and height. Accutane’s primary function is to decrease and clear body acne by decreasing the size and bacterial output of the sebaceous glands but its side effects are more detrimental than the healing process it is supposed to provide for its users.

The line in the building was very interesting to me because the lines are what make the form of the building. They mostly go horizontal but there is also some vertical lines thrown in to add texture and balance the building out with all of the intricate detail. The repetition in the hospital created a type of unity feeling for me with the repeated colors, shapes and furniture through the whole building. I really appreciated the way that the hospital was organized with different sections of the hospital representing different specialties like dermatology and pediatric care. Phoenix Children’s Hospital does an amazing job with stimulating the senses and I believe that for being a children’s hospital stimulating the senses is very important. It’s important because the children that go to the hospital need to feel that it’s a fun place to go to make them comfortable and feel at ease, especially if they are sick, injured or even suffering from a disease.
