| General Information About Hairy Cell Leukemia |
| Hairy cell leukemia is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). Hairy cell leukemia is a cancer of the blood and bone marrow. This rare type of leukemia gets worse slowly or does not get worse at all. The disease is called hairy cell leukemia because the leukemia cells look "hairy" when viewed under a microscope. Normally, the bone marrow makes blood stem cells (immature cells) that develop into mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. The myeloid stem cell develops into one of three types of mature blood cells: - Red blood cells that carry oxygen and other materials to all tissues of the body.
- White blood cells that fight infection and disease.
- Platelets that help prevent bleeding by causing blood clots to form.
The lymphoid stem cell develops into a lymphoblast cell and then into one of three types of lymphocytes (white blood cells): - B lymphocytes that make antibodies to help fight infection.
- T lymphocytes that help B lymphocytes make antibodies to help fight infection.
- Natural killer cells that attack cancer cells and viruses.

A blood stem cell goes through several steps to become a red blood cell, platelet, or white blood cell. | In hairy cell leukemia, too many blood stem cells develop into lymphocytes. These lymphocytes are abnormal and do not become healthy white blood cells. They may also be called leukemic cells. The leukemic cells can build up in the blood and bone marrow so there is less room for healthy white blood cells, red blood cells, and platelets. This may cause infection, anemia, and easy bleeding. Some of the leukemia cells may collect in the spleen and cause it to swell. This summary is about hairy cell leukemia. See the following PDQ summaries for information about other types of leukemia: - Adult Acute Lymphoblastic Leukemia Treatment.
- Childhood Acute Lymphoblastic Leukemia Treatment.
- Chronic Lymphocytic Leukemia Treatment.
- Adult Acute Myeloid Leukemia Treatment.
- Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies Treatment.
- Chronic Myelogenous Leukemia Treatment.
Gender and age may affect the risk of developing hairy cell leukemia. Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. People who think they may be at risk should discuss this with their doctor. The cause of hairy cell leukemia is unknown. It occurs more often in older men. Possible signs of hairy cell leukemia include tiredness, infections, and pain below the ribs. These and other symptoms may be caused by hairy cell leukemia. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur: - Weakness or feeling tired.
- Fever or frequent infections.
- Easy bruising or bleeding.
- Shortness of breath.
- Weight loss for no known reason.
- Pain or a feeling of fullness below the ribs.
- Painless lumps in the neck, underarm, stomach, or groin.
Tests that examine the blood and bone marrow are used to detect (find) and diagnose hairy cell leukemia. The following tests and procedures may be used: - Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as a swollen spleen, lumps, or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
- Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following:
- The number of red blood cells, white blood cells, and platelets.
- The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.
- The portion of the sample made up of red blood cells.
| Enlarge | |  | | Complete blood count (CBC). Blood is collected by inserting a needle into a vein and allowing the blood to flow into a tube. The blood sample is sent to the laboratory and the red blood cells, white blood cells, and platelets are counted. The CBC is used to test for, diagnose, and monitor many different conditions. |
- Peripheral blood smear: A procedure in which a sample of blood is checked for cells that look "hairy," the number and kinds of white blood cells, the number of platelets, and changes in the shape of blood cells.
- Bone marrow aspiration and biopsy: The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for signs of cancer.

- Immunophenotyping: A test in which the cells in a sample of blood or bone marrow are looked at under a microscope to check the pattern of proteins that are on the surface of the cells. Hairy cells have a certain pattern.
- CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. A CT scan of the abdomen may be done to check for swollen lymph nodes or a swollen spleen.
Certain factors affect treatment options and prognosis (chance of recovery). The treatment options may depend on the following: - The number of hairy (leukemia) cells and healthy blood cells in the blood and bone marrow.
- Whether the spleen is swollen.
- Whether there are symptoms of leukemia, such as infection.
- Whether the leukemia has recurred (come back) after previous treatment.
The prognosis (chance of recovery) depends on the following: - Whether the hairy cell leukemia does not grow or grows so slowly it does not need treatment.
- Whether the hairy cell leukemia responds to treatment.
Treatment often results in a long-lasting remission (a period during which some or all of the signs and symptoms of the leukemia are gone). If the leukemia returns after it has been in remission, retreatment often causes another remission.

| Male Pattern Baldness |
For most the thought of losing their hair is disturbing. For some words such as male-pattern baldness or androgenic alopecia are newly familiar terms which give them the same warm and fuzzy feeling as having a flat tire on the way to the airport. In this informational article titled male-pattern baldness we will dissect the condition and make a few helpful suggestions as to how you can slow its unrelenting march.
Male-pattern baldness is known in medical terms as androgenetic alopecia. This condition is a genetic based hormone facilitated form of balding that affects both men and women. Some estimates have this condition affecting up to 90% of the population. To better understand why this happens take a few minutes to walk with me through the technical aspect of this confidence bursting condition.
The human scalp is filled with over 100,000 hairs; each of which spring forth from a pouch like sac known as the follicle. Every day there is a delicate balance of hair loss and hair regrowth taking place right on top of your head with approximately125 hairs being lost only to be replaced. The head hair replacement mediator is a cranky enzyme called 5 alpha reductase type 2 which converts testosterone to dihydrotestosterone (DHT). When too much DHT is produced new hair growth is for the most part paralyzed and your existing hair becomes fine and brittle. DHT also interrupts the growth phase and accelerates the number of hairs lost.
Most men with this condition first notice it on the top of the head with perhaps slight balding on the crown. They are also likely to experience a receding hair line. For those men, whose hair loss started in their teens, they likely will lose all of the hair on top of their head but retain hair on the sides and back of the scalp.
In women, hair loss begins on top of the head and is generally recognized as an overall thinning process rather than complete hair loss. They are fortunate in that the receding hair line so prominent in men is not often a part of the process. In women the condition is appropriately called female-pattern baldness.
What can be done!
If is probably fairly obvious by now that any success treatment must have a component that blocks DHT's ability to interrupt the hair replacement cycle. There are a couple of herbs that have been effective in this pursuit with the most well known being Saw Palmetto. The next step is to find a product that is rich in vitamins and extracts that can provide a fertile ground for hair regrowth. And lastly, consider a topical hair growth stimulator such as minoxidil or perhaps a natural blend of stimulating oils (almond, pumpkinseed) to accelerate hair growth.
In summary, there are no easy answers. Chances are if you have already lost most of your hair due to male-pattern baldness your options will be limited to surgery, a hairpiece, or loving your partially bald new look. On the other hand if only a moderate to small amount of balding has occurred, your chances of slowing and possibly reversing the condition are very good. If you fall in this category there are a number of excellent hair regrowth products formulated specifically for treating male-pattern baldness that are worth considering. |

| Dihydrotestosterone (DHT) |
Chances are you have heard the name DHT. And if you haven't the chances are virtually 100% that you have DHT floating around in your system and there is a 90% chance that it may be having an effect on your appearance.
Dihydrotestosterone is a form of testosterone that is one of the primary factors responsible for androgenic alopecia; more commonly known as male pattern baldness in men and female pattern baldness in women. Many experts in the hair regrowth industry simply refer to it as the hair loss hormone. While this description is accurate perhaps a better description would be the hair loss mediating hormone.
The hair cycle includes two major phases: the growth phase and the resting phase. The growth phase last from 4 to 5 years while the resting phase last two to three years. Unbeknownst to most people there is a delicate balance of hair loss and hair replacement going on right on top of their head. Every day about 125 hairs are lost with most being replaced and the cycle continues virtually unnoticed.
The main traffic cop sitting on top of our head is a hair cycle control officer known as 5 alpha reductase type 2 whose sole purpose is to convert testosterone to DHT. Over several hair cycles dihydrotestosterone causes hair to become finer and shorter. This unsavory traffic cop also is obsessed with stopping the traffic on the growth side of the road while letting an unusually large number of cars pass on the resting side, leading to a giant stack up.
In summary, DHT (dihydrotestosterone) is a concentrated form of testosterone that damages hair quality and growth.
Its effects can be seen in men as hair loss usually beginning at the forehead or on the top of the head toward the back. Some men lose only some of their hair and have only a receding hairline or a small bald spot in the back. Others are not so lucky, especially those individuals whose hair loss started at an early age and has been advancing ever since. For these men it is likely they will lose all of the hair on top of the head, but will retain hair on the sides and back of the scalp.
In women, hair loss begins on the top of the head and is usually a thinning of the hair rather than total and complete loss of hair. Women generally don't experience the dreaded receding hair line.
If you feel you may be one of the 90% affected adversely by DHT there is good and bad news. The bad new is if you have lost a great deal of hair there are no really good answers beside hair transplant surgery. On the other hand if you are one of the lucky ones who have recognized the condition early it can be slowed or even reversed. There are some excellent hair regrowth products designed to reduce or block DHT levels and supply the scalp with nutrition designed to promote healthy hair growth. If you are looking to improve your appearance through slowing or reversing androgenic alopecia this is an option worth considering. |

| Balding and Testosterone |
Balding and testosterone is an interesting area of discussion. It is ironic that the hormone most closely linked to male virility can in fact be the cause of hair loss in both men and women. Testosterone is one of a family of hormones called Androgens which are produced primary within the cells inside the testicles. In women testosterone is produced in very small amounts in the ovaries and adrenal glands. Testosterone in its original form does not cause balding but when hair follicles convert this vital androgenic hormone into another more powerful hormone known as dihydrotestosterone (DHT) a condition known as male pattern baldness in men and female pattern baldness in women can occur.
The human scalp is covered with an estimated 100,000 hairs. These tiny strands spring forth from a small pouch like sacs called a follicle. A complete hair cycle includes two major phases: the growing phase, which lasts four to six years, and the resting phase which lasts two to three months. But hair growth cannot go unchecked; there must be a hair cop on board to make sure that the hair replacement cycle is carried out as planned. This cop is an enzyme known as 5 alpha reductase type 2 and when he gets cranky bad things happen. If he decides to be a whirlwind of DHT production balding or thinning is sure to follow. It may not be noticed immediately due to the vast number of scalp hairs but over time the loss of hair will become problematic. Men will begin to notice a receding hair line combined with thinning on the top. Women will notice a more evenly distributed thinning process that may cover the entire scalp, which generally begins later in life. The differences in how androgenic alopecia presents itself has to do with overall testosterone levels and differences in the pattern of hormone receptors and enzymes in the scalps of men and women.
Testosterone related balding accounts for an estimated 90% of all cases of hair loss. One in every four men begins losing his hair by age 30; the remaining two thirds start balding by age 60.
What can be done? This is the question that millions of men and women who have been victimized by the hair loss bandit, AKA androgenic alopecia, are asking. The good news is if the condition is recognized early there are a number of excellent hair regrowth products which are specifically formulated to slow and possibly reverse the condition. On the other hand if balding and testosterone (DHT) levels have gotten out of hand and allowed to cause extensive hair loss over time your options will be limited. This is truly one of the conditions where early treatment may make the difference in being able to keep your precious hair or joining the ranks of the bald is beautiful club. |

| Stop Receding Hairline - Act Now Or Go Bald! |
Many men and women want to learn how to stop receding hairline but they don't know what to do first. Noticing that your hair is receding can be hard to accept. After all, a receding hairline is usually the first sign for male pattern baldness. Do you know why your hairline is receding? For men, the reason that they start losing hair at the temples is usually because of Dihydrotestosterone (DHT). DHT shrinks the hair follicles over time until the hair is no longer visible. This is why acting fast is crucial if you want to stop your hair loss. Hair Generally has 3 phases: Anagen - 90% of your hair is in this growth phase. This phase lasts between 2 to 6 years. Catagen - Hair becomes thinner and the follicle will start shrinking. Last 3-4 weeks. Telegen - the thinned hairs will fall out to make way for the new hairs to grow in. lasts for 2-4 months If you start to block the DHT you will slow down your hair loss and you will start to regrow some of what you have lost. There are a few quality hair regrowth products on the market that are FDA approved to regrow hair. These products generally have the ingredient Minoxidil which helps inhibit the DHT. When you start using a hair regrowth product it will take approximately 2 months before you start to see results. Why Do Results Take So Long To Notice? Looking at your hair everyday to see if it is regrowing can be a frustrating. Just because you can't notice anything doesn't mean that the treatment is ineffective. Hair doesn't grow very fast so it is hard to tell how effective a treatment is. A BIG mistake many people make is they quit using a product 2 months in because they think that it's not working. It takes time to stop receding hairline. The problem with quitting is because the product might be working by keeping you from losing more hair. Always give a product at least 6 months before you decide if it is working or not. |

| How to Repair Split Ends |
Do you have small wisps of hair sticking out from the ends of your locks? These are split ends. Not only do they ruin a great hairstyle, but split ends also make your hair look unhealthy and unruly. Don't fret, though because there are ways to split with split end problems. What You'll Need: * Moisturizing shampoo and conditioner * Wide toothed comb * Soft-bristled brush * Towel * Sharp scissors * Quick fix split end products * Avocado * Mayonnaise * Olive oil Split End Preventive Measures The best way to repair slit ends is to prevent them from appearing in the first place. Preventive measures involve changing several hygienic practices. Here are some tips to remember. Wash And Dry Your Hair Properly When you wash your hair, wet it with warm, not hot water, then use a moisturizing shampoo and conditioner. Warm water allows the hair cuticles to open, so the conditioner goes into the hair shaft immediately, and starts moisturizing it. Condition your hair properly, leaving it for three to five minutes. If possible, wrap your hair in a towel and leave the conditioner for a few minutes. Afterwards, rinse out the conditioner using cool water, sealing the hair shaft. If your hair is well-conditioned, you can control the appearance of split ends in the future. When you dry your hair, don't squeeze it or rub the towel on it. Instead, pat it with a towel gently. Avoid too much blow-drying, too. Brush Your Hair The Right Way If you wish to brush your hair while it's still wet, use a wide-tooth comb instead of a regular brush. If your hair's already dry, use a soft-bristled brush. Comb gently, avoiding tugging or pulling on your hair. If you encounter tangles, try to undo them with your fingers and not the comb. Also, avoid combing and brushing hair too much. Excessive brushing can cause more damage than good. Relax In Between Treatments If your hair is often exposed to harsh chemical treatments (such as coloring, relaxing or rebonding), it looses moisture easily, making it prone to breakage. Make it a point to relax your hair in between treatments. Wait at least a month or so after, before you undergo another treatment. Another tip: don't color and relax your hair at the same time. Try A Natural, Homemade Product Preparing a natural home treatment mix is a great way to protect your hair ends from splitting in the future. These can be time consuming and messy, but the results are certainly worth it. * Apply mayonnaise on your hair once a week, using it like a conditioner, Rinse it well. * Mash up some avocado add some hot olive oil, then leave it on your hair. Cover with a towel and leave it there for 20 minutes. Afterward, rinse it. |

| Hair Replacement Systems and Modern Materials |
Hair replacement systems are a modern reinvention of the traditional wig using up to date materials, hand finishing and custom fitting. They offer a reliable alternative to other more permanent hair replacement solutions and involve no hair surgery. The modern materials used are the secret to their acceptance compared to the old fashioned wig. They have managed to deal with the stereotypic unnatural look and the fear of the whole thing slipping off. For this reason people should take a fresh look at what is on offer. The design of hair replacement systems and the selection of materials to be used depend on two seemingly conflicting desires from people. It depends on how important you feel appearance is compared to durability. Clearly people would like both. A hair piece that looks natural and can't be identified by the general public together with one that remains in place and lasts a long time. You really need to select the materials based on your requirements, but somewhere along the line you will need to make some compromises. The main differences come into the making of the base materials that the hair is attached to. Ideally, people like to think that close examination of their scalp will not reveal the hair piece. They want their scalp to look as natural as possible and merge with the features of their own skin. However, the materials used to make near invisible bases are often the most delicate on offer. An example of this are the bases made from ultra fine lace. Here the lace is made of such fine threads that it is very hard to see. The threads used are either made from nylon or polyester. Add to this a system of bleaching the knots used to tie the hair on and you have a base that is virtually undetectable during normal use. Due to the very light nature of the materials these systems are also very light weight and therefore comfortable and cool to wear. Comfort and overheating are the common complaints about traditional wigs. The problems arise due to the delicate nature of the lace. It can easily get torn and damaged. It is also vulnerable to attack from acids produced in sweat. This means that lace hair systems have a limited life and often ongoing repairs have to be made. In terms of hair pieces lasting a long time and being very resilient the base materials used to do this job are silicone and polyurethane. These two materials are used together due to their individual properties. The silicone is very durable which adds strength and longevity to the base. It is also resistant to the corrosive elements produced in sweat. Unfortunately silicone doesn't colour very well with dyes and this is where polyurethane comes in. Although polyurethane is not as durable as silicone and attacked by skin acids it can be easily dyed to resemble the scalp skin tones. This is why the two materials are often used together in the same base. Due to the fact that these materials aren't permeable to water and air they are said to not breathe. This means that they are often seen as warm and uncomfortable to wear. As can be seen, the choice of base materials for hair replacement systems is critical to their acceptability by the people wearing them. If you are looking for a hair piece you should carefully weigh up what you are expecting to get from it and the properties that the base materials offer. |
