Yes, cicatricial alopecias are classified as primary or secondary. This discussion is confined to the primary cicatricial alopecias in which the hair follicle is the target of the destructive inflammatory process. In secondary cicatricial alopecias, destruction of the hair follicle is incidental to a non-follicle-directed process or external injury, such as severe infections, burns, radiation, or tumors.

The term "cicatricial alopecia" refers to a diverse group of rare disorders that destroy the hair follicle, replace it with scar tissue, and cause permanent hair loss. In some cases, hair loss is gradual, without symptoms, and is unnoticed for long periods. In other cases, hair loss is associated with severe itching, burning and pain and is rapidly progressive.

The word alopecia itself is a term specifically used for hair loss yet there are many subtypes of alopecia. These are the three primary subtypes of alopecia: Alopecia Areata - Patchy loss of hair whether that means patches on your legs, arms, pubic region, scalp, lashes or brows. Each of the terms are for more descriptive purposes since the each of the types can sometimes be vague and symptoms may seem to "overlap" each other in places.

The cause of the various cicatricial alopecias is poorly understood. However, all cicatricial alopecias involve inflammation directed at the hair follicle, usually the upper part of the follicle where the stem cells and sebaceous gland (oil gland) are located. If the stem cells are destroyed, and the sebaceous gland as well, there is then no possibility for regeneration of the hair follicle and permanent hair loss results.

Alopecia is considered to be an autoimmune disease, in which the immune system, which is designed to protect the body from foreign invaders such as viruses and bacteria, mistakenly attacks the hair follicles, the tiny cup-shaped structures from which hairs grow. This can lead to hair loss on the scalp and elsewhere. In most cases, hair falls out in small, round patches about the size of a quarter. In many cases, the disease does not extend beyond a few bare patches.

Alopecia areata is a common autoimmune disease that results in the loss of hair on the scalp and elsewhere. It usually starts with one or more small, round, smooth patches. It occurs in males and females of all ages and races, but onset most often occurs in childhood. It is estimated that approximately two percent of the population will be affected at some point in their lives, or over 4.5 million people in the United States.

Cichlid-only community tanks-- usually with non-cichlid scavengers-- are very common in the cichlid hobby. Experienced cichlid keepers often find unlikely combinations of cichlids which work well by chance (e.g. a shortage of tank space, or a fish jumping into another tank). Aquarists will commonly attempt to group fish of similar geographical origin, e.g.

Several lineages of Reiki are now in the Western world, all of which trace their origins back to Dr. Usui. Following the death of Hawayo Takata in 1980, the unitary tradition of Reiki she espoused in North America quickly branched out, and several versions of Reiki are now found in various parts of the world. Most have taken the traditional Usui Reiki and added to or subtracted from it to come up with their variation. Imagine a tree. It has a single trunk but it has many branches.

Cholesterol travels through the blood attached to a protein. This package of cholesterol (a lipid) and protein is called a lipoprotein. Lipoproteins are either high-density or low-density, based on how much protein and fat they have. Low-density lipoproteins (LDL) are the "bad" cholesterol. LDL is mostly fat with only a small amount of protein. It can clog your arteries. If you have high cholesterol, your doctor will want you to lower your LDL.

PHYSICAL: Shaking, beating, burning, failure to provide necessities of life (e.g., adequate food, clothing, shelter, medical care). A child is physically injured by other than accidental means. A child is being subjected to willful cruelty or unjustifiable punishment. Any kind of contact with a child could be considered a sexual act. It will depend on the intent of the person making the contact.

There are several species or kinds of lice that feed on people. One species feeds specifically on the head and is called the head louse.

There are many kinds of clinical trials. They range from studies of ways to prevent, detect and diagnose, control and treat cancer, to studies of the psychological impact of the disease and ways to improve the patient's comfort and quality of life (including pain control). Most cancer clinical trials deal with new treatments.

With so many lenses available, it is difficult to find ones that will protect your eyes if you don't know what each one will do. Blue-blockers block blue light and usually have amber lenses. Researchers are still unsure whether or not blue light is harmful, but these are popular among skiers, hunters, boaters, and pilots. Both polarized lenses and anti-reflective coating cut reflected glare. Polarized lenses in particular are popular with those who play water and snow sports.

Research continues to verify that touch is a crucial element in the proper physical and psychological development of children. Infant massage is an activity that provides many proven and potential benefits to infants and their parents. Massage also assists a baby in discovering their body, potentially improves flexibility, and strengthens their self-esteem.

There are numerous types of massage and bodywork; various techniques utilize different strokes, including basic rubbing strokes, rocking movement, effleurage, petrissage, taponment, posture and movement re-education, application of pressure to specific points, and more. Ask the practitioner about the methods he or she uses.

There are two basic cell types of melanoma as seen with the microscope. These are spindle and epithelioid. Most melanomas have a combination of these 2 cell types. Only if the eye is removed or the tumor resected can the doctor judge the cell type. Melanomas with predominantly spindle cells have thin elongated cells and imply better prognosis. Epithelioid cell type melanoma have round cells and imply worse prognosis.

CBT is not at all like traditional psychotherapy. In traditional psychotherapy, the focus is often on talking about one's past. Talking about the past can be very helpful in dealing with many life issues, but it has very limited value in helping people to overcome panic disorder. CBT focuses on overcoming panic in the present, as opposed to searching the past for contributing factors. In CBT, you learn skills that you practice in the therapist's office and on your own.

Most definitely yes, and it's a good thing considering there are so few traditional jobs for astronomers! Ph.D. astronomers can be employed in a variety of technical fields, since astronomy itself is so multi-disciplinary. Many astronomers in the 1970's found themselves employed by the defense and aerospace industries.

Product certification attests that a product complies with the safety, fitness for use and/or interchangeability characteristics defined in standard(s), and in specification(s) supplementary to standards, where they are requested by the market. Organization certification demonstrates the conformity of, for example, an organization's quality, environmental or other management system to the relevant management system standard(s).

Yes. In fact, there are some plants that have been discovered that do not respond to gravity. These are being used in research to determine how various plants sense and respond to gravity.

A.: Probably because certain ink companies promote this phenomenon as a way to get your business. The reason a sheetfed printing ink doesn’t perform very well on a particular press is because either the original ink was bad to start with or the press has some mechanical problems that require the use of some special additive to overcome a particular problem. I remember as a teenager, my buddies and I each had a different opinion about which gasoline ran best in our respective cars.

Unlike stretching or fitness, yoga is more than just physical postures. Patanjali's eight-fold path illustrates how the physical practice is just one aspect of yoga. Even within the physical practice, yoga is unique because we connect the movement of the body and the fluctuations of the mind to the rhythm of our breath. Connecting the mind, body, and breath helps us to direct our attention inward.

The use of lasers in medicine is complex. It is important for the patient to realize that lasers have specific applications. The choice of the laser depends upon many factors, including the surgeon's experience, the size of the area to be treated, and the expectations of the patient. Your surgeon will decide if a laser is appropriate, and which laser is best for the situation. There are constant technologic advances which lead to even new applications of future generations of lasers.

There are three main categories of anesthesia: local, regional, and general. Each has many forms and uses. In local anesthesia, the anesthetic drug is usually injected into the tissue to numb just the specific location of your body requiring minor surgery, for example, on the hand or foot. In regional anesthesia, your anesthesiologist makes an injection near a cluster of nerves to numb the area of your body that requires surgery. You may remain awake, or you may be given a sedative.

Sinusitis can be divided into acute, chronic and recurrent. The classifications are based on length of symptoms, or the specific sinus involved, or both. The classification is as follows: Acute sinusitis: symptoms for less than 4 weeks consisting of some or all of the following: persistent symptoms of an upper respiratory tract infection, purulent rhinorrhea, postnasal drainage, anosmia, nasal congestion, facial pain, headache, fever, cough, and purulent discharge.

We suggest a digestive formula such as OxiCellZyme or DigestZyme at the beginning of the meal because that is when the digestive process begins. You will want the enzymes available as soon as possible to assist the digestive process. However, if you forget, then it is perfectly fine to take them in the middle, at the end, or whenever you remember, as digestion lasts several hours.

There are two types of fiber, both of which can promote regularity and are found in naturally healthy foods. Soluble fiber, the key ingredient in fiber therapy products, is found in oats, apples, barley and many other foods. It dissolves in water. Psyllium and methylcellulose are both soluble fibers, but methylcellulose does not ferment in the intestines and cause gas. Insoluble fiber is found in whole g rains, nuts and many vegetables. It does not dissolve in water.
