Botanical Name : Pueraria mirifica
Family: Fabaceae
Subfamily: Faboideae
Genus: Pueraria
Species: P. mirifica
Kingdom: Plantae
Order: Fabales

Common Name :Kwao Krua, Khao Krua Kao, or Kwao Kreu Kao (white root) and Kwao Krua Dang (red root Butea Superba),

Habitat :Pueraria mirifica  is a native herb abundant in the jungles of the north Thailand and Burma.

Description:
The Pueraria mirifica plant is found only in Thailand. Even though there have been reports of findings of plants in the same family of “Pueraria” in Asian countries, these plant are of different species and possess different qualities from Pueraria mirifica. From the study, there are nine species [as many as thirteen have now been reported] of Pueraria in Thailand. This article discussing the efficacy and safety study of Pueraria mirifica refers only to Pueraria candollei var. mirifica from central part of the country. Pueraria mirifica is a climbing plant, usually grows in a mountainous area by tiding with trees. There are three small leaves on each branch and purple blooms on the top. The tubers on its root are round, and stay underground. When cut, white liquid like skim milk would come out. The Shape and size of Pueraria mirifica are diverse up to the environment in which it exists. Active ingredients are found at the roots from which extracts are made.

History:
Arimuttama was the old capital of the Pookham City of Myanmar. They had a sacred Buddhist precinct and one-day the sacred Buddhist precinct was broken down. The Buddhist monks found this ingredient that was inscribed on the palm leaf and placed it in the sacred Buddhist precinct.

To take the tuberous root of Pueraria with big leaves, pound and blend with cow’s milk. The benefits of this medicine is to support memory, talk big, and be able to remember three books of the astrology, make the skin smooth like six year old kid, live more than 1,000 years and parasite diseases are not able to be of trouble

There are 4 varieties of kwao krua that are considered beneficial and can be used for medicinal, food supplementary and cosmetic purposes. They are White Kwao Krua (Pueraria mirifica), Red Kwao Krua (Butea superba), Black Kwao Krua and Dull Grey Kwao Krua. Local communities in Thailand have used Pueraria mirifica for well over one hundred years, specifically for its supposed rejuvenating qualities

Uses:
Pueraria mirifica, also known as ‘white kwao krua’, is a natural tuberous herbal root and contains high levels of natural phytoestrogens including miroestrol, deoxymiroestrol, daidzein, genistin, genistein, B-Sitosterol, stigmasterol, coumestrol, pueraria, campesterol, mirificoumestan, kwakhurin, and mirificine.

Some cosmetic products and herbal supplements claim various health benefits of the extracts of Pueraria mirifica including increasing appetite, enlarging breasts, improving hair growth, and other rejuvenating effects; however, there is no scientific evidence to support any these claims.   The U.S. Federal Trade Commission has taken action against manufacturers who make such fraudulent claims

Medicinal Uses:
Preliminary data from a clinical trial conducted in Thailand to study the beneficial effect of Pueraria mirifica supplement have recently been obtained. Eight female subjects who were having menopausal symptoms received Pueraria mirifica in the form of capsule once daily at the dose of 200 mg for 4 months followed by the dose of 100 mg, for 8 months. Improvement of menopausal symptoms was observed in 5 out of 8 subjects throughout the study period. Physical examinations and biochemical studies revealed that all subjects were healthy. The dietary supplement dose of Pueraria mirifica recommended by the physician for its estrogenic effect in this case is 100 mg per day.

A series of studies involving breast cell lines and the activity of Pueraria mirifica in vitro have been performed by the Emory University School of Medicine in Atlanta, Georgia, USA, and the Department of Obstetrics and Gynecology, Phramongkutklao College of Medicine, Bangkok, Thailand. These studies have shown that Pueraria mirifica root extract (Smith Naturals Co Ltd., Bangkok) has potent anti-estrogenic properties against aggressive cell cancer lines in vitro, especially the proliferative estrogen receptor-positive (ER+) breast cancer lines (T47-D, MCF-7, and ZR-75-1) obtained from the MD Anderson Cancer Institute (Texas) and the National Cancer Institute (NCI) at the U.S. National Institutes of Health (NIH).

Tectorigenin, an isoflavone present in kudzu, demonstrated antiproliferative activity against human cancer (HL-60) cells. The proposed mechanisms are induction of differentiation in the cells and a reduction in the expression of Bcl-2, an antiapoptotic protein. In addition, isoflavones in Pueraria mirifica are thought to be involved in alleviating symptoms such as hot flashes and night sweats in perimenopausal women and affect cognitive function in postmenopausal women. The isoflavones present in kudzu root extract are also thought to suppress alcohol intake and alcohol withdrawal symptoms in mice although the mechanism is unclear. The anti-inflammatory property of kudzu is attributed to its ability to decrease Prostaglandin E2 and tumor necrosis factor (TNF)-alpha release, both of which are involved in inflammatory process. The flowers of Pueraria thunbergiana exhibit protective effects against ethanol-induced apoptosis in human neuroblastoma cells by inhibiting the expression of a protease, caspase-3 that is responsible for proteolytic cleavage of many proteins.

Herbal Breast Enlargement by Pueraria mirifica. In 90% of women, the phytoestrogen from Pueraria herbal will induce the increasing of the cell turgidity but not cell multiplication or proliferation.

Kidney transplant

Introduction:
A kidney transplant is an operation that places a healthy kidney in your body. The transplanted kidney takes over the work of the two kidneys that failed, and you no longer need dialysis.

CLICK  & SEE
During a transplant, the surgeon places the new kidney in your lower abdomen and connects the artery and vein of the new kidney to your artery and vein. Often, the new kidney will start making urine as soon as your blood starts flowing through it. But sometimes it takes a few weeks to start working.

If you have advanced and permanent kidney failure, kidney transplantation may be the treatment option that allows you to live much like you lived before your kidneys failed. Since the 1950s, when the first kidney transplants were performed, much has been learned about how to prevent rejection and minimize the side effects of medicines.

But transplantation is not a cure; it’s an ongoing treatment that requires you to take medicines for the rest of your life. And the wait for a donated kidney can be years long.

Many transplanted kidneys come from donors who have died. Some come from a living family member. The wait for a new kidney can be long. People who have transplants must take drugs to keep their body from rejecting the new kidney for the rest of their lives.

A successful transplant takes a coordinated effort from your whole health care team, including your nephrologist, transplant surgeon, transplant coordinator, pharmacist, dietitian, and social worker. But the most important members of your health care team are you and your family. By learning about your treatment, you can work with your health care team to give yourself the best possible results, and you can lead a full, active life.

Around 40 per cent of patients with end-stage renal failure (ESRF) need a transplant which frees people from the need for dialysis treatments.

A successful kidney transplant has ten times the function of dialysis (for example ten times the ability to remove toxins and extra water from the blood). It means that transplant patients have a better quality of life, with more energy than they did on dialysis.

How transplants work:-
An assessment is necessary to determine whether your body will accept an available kidney. This may require several visits over four to six months, and all potential recipients must be healthy enough for surgery.

Although there is no age limit, few units will transplant patients over 70 years – unless very fit.

If a family member, partner or friend wants to donate a kidney, they will need to be evaluated for general health too.

If there is no potential living donor, you will need to register with hospital and be put on a national waiting list to receive a kidney from a deceased donor. but this varies considerably around the country. Kidneys can also be donated by strangers.

If there is a suitable living donor, the operation can be scheduled in advance, when it suits both sides. If you’re on a waiting list for a deceased donor kidney, as soon as it becomes available, you must go to the hospital quickly – where a test is carried out to check the kidney won’t be rejected. If it’s suitable, the transplant can proceed. The operation usually takes three to four hours.

A surgeon places the new kidney inside your lower abdomen and connects the artery and vein of the new kidney to your artery and vein. Your blood flows through the new kidney, which makes urine, just like your own kidneys did when they were healthy. Unless they are causing infection or high blood pressure, your own kidneys are left in place.

During the operation, the transplant kidney is inserted into the lower abdomen and connected to an artery and vein (to the leg). The blood flows through the new kidney, which makes urine, just like the old kidneys did when they were healthy. The old kidneys are usually left in place.

CLICK & SEE

Often the new kidney will start making urine as soon as blood starts flowing through it, but about one third of patients will require dialysis for around a week. Most patients leave hospital two weeks after the operation.

To prevent the immune system from seeing the new kidney as foreign and rejecting it, you’ll have to take drugs that turn off (or suppress) your immune response (immunosupressants). It’s important to understand the instructions for taking these medicines before leaving hospital, as missing the tablets for just 24 hours can cause rejection and the loss of the kidney.

Recovery From Surgery:-
As after any major surgery, you’ll probably feel sore and groggy when you wake up. However, many transplant recipients report feeling much better immediately after surgery. Even if you wake up feeling great, you’ll need to stay in the hospital for about a week to recover from surgery, and longer if you have any complications.

Posttransplant Care:-
Your body’s immune system is designed to keep you healthy by sensing “foreign invaders,” such as bacteria, and rejecting them. But your immune system will also sense that your new kidney is foreign. To keep your body from rejecting it, you’ll have to take drugs that turn off, or suppress, your immune response. You may have to take two or more of these immunosuppressant medicines, as well as medications to treat other health problems. Your health care team will help you learn what each pill is for and when to take it. Be sure that you understand the instructions for taking your medicines before you leave the hospital.

If you’ve been on hemodialysis, you’ll find that your posttransplant diet is much less restrictive. You can drink more fluids and eat many of the fruits and vegetables you were previously told to avoid. You may even need to gain a little weight, but be careful not to gain weight too quickly and avoid salty foods that can lead to high blood pressure

Rejection:-
You can help prevent rejection by taking your medicines and following your diet, but watching for signs of rejection—like fever or soreness in the area of the new kidney or a change in the amount of urine you make—is important. Report any such changes to your health care team.

Even if you do everything you’re supposed to do, your body may still reject the new kidney and you may need to go back on dialysis. Unless your health care team determines that you’re no longer a good candidate for transplantation, you can go back on the waiting list for another kidney.

Side Effects of Immunosuppressants:
Immunosuppressants can weaken your immune system, which can lead to infections. Some drugs may also change your appearance. Your face may get fuller; you may gain weight or develop acne or facial hair. Not all patients have these problems, though, and diet and makeup can help.

Immunosuppressants work by diminishing the ability of immune cells to function. In some patients, over long periods of time, this diminished immunity can increase the risk of developing cancer. Some immunosuppressants cause cataracts, diabetes, extra stomach acid, high blood pressure, and bone disease. When used over time, these drugs may also cause liver or kidney damage in a few patients.

Hope through Research:-
The NIDDK, through its Division of Kidney, Urologic, and Hematologic Diseases, supports several programs and studies devoted to improving treatment for patients with progressive kidney disease and permanent kidney failure, including patients who receive a transplanted kidney.

•The End-Stage Renal Disease Program promotes research to reduce medical problems from bone, blood, nervous system, metabolic, gastrointestinal, cardiovascular, and endocrine abnormalities in kidney failure and to improve the effectiveness of dialysis and transplantation. The program seeks to increase kidney graft and patient survival and to maximize quality of life.

•The NIH Organ/Tissue Transplant Center, located at the NIH Clinical Center in Bethesda, MD, is a collaborative project of NIH, the Walter Reed Army Medical Center, the Naval Medical Research Center, and the Diabetes Research Institute at the University of Miami. The site includes a state-of-the-art clinical transplant ward, operating facility, and outpatient clinic designed for the study of new drugs or techniques that may improve the success of organ and tissue transplants.

•The U.S. Renal Data System (USRDS) collects, analyzes, and distributes information about the use of dialysis and transplantation to treat kidney failure in the United States. The USRDS is funded directly by NIDDK in conjunction with the Centers for Medicare & Medicaid Services. The USRDS publishes an Annual Data Report, which characterizes the total population of people being treated for kidney failure; reports on incidence, prevalence, mortality rates, and trends over time; and develops data on the effects of various treatment modalities. The report also helps identify problems and opportunities for more focused special studies of renal research issues.

Feeding Problems

Definition:
Feeding problem of infancy or early childhood is characterized by the failure of an infant or child under six years of age to eat enough food to gain weight and grow normally over a period of one month or more. The disorder can also be characterized by the loss of a significant amount of weight over one month. Feeding disorder is similar to failure to thrive, except that no medical or physiological condition can explain the low food intake or lack of growth.
CLICK & SEE THE PICTURES

Infants and children with a feeding disorder fail to grow adequately, or even lose weight with no underlying medical explanation. They do not eat enough energy or nutrients to support growth and may be irritable or apathetic. Factors that contribute to development of a feeding disorder include lack of nurturing, failure to read the child’s hunger and satiety cues accurately, poverty, or parental mental illness. Successful treatment involves dietary, behavioral, social, and psychological intervention by a multidisciplinary

Feeding problems are common throughout childhood and affect both boys and girls.

Causes:
The kind of feeding problem may depend on the age of the child.

Some new mothers take a while to get the hang of breastfeeding and may worry they’re not producing sufficient milk or their baby isn’t satisfied. But as long as the baby is gaining weight at the normal rate, there’s no need for concern.

Occasionally, early feeding problems are due to anatomical difficulties (for example, a severe cleft palate or oesophageal atresia) or more general illness, but these are usually quickly identified.

Minor infections, such as a cold, can interrupt established feeding patterns, but rarely for long.

Gastro-oesophageal reflux disease (GORD) can also make feeding difficult, affect weight gain and cause great stress for parents.

More serious conditions can interfere with the absorption of food and weight gain, including coeliac disease, cystic fibrosis, inflammatory bowel disease and food intolerance.

In toddlers and older children, emotional and social factors can cause feeding problems. Older children, especially girls, are more likely to develop eating disorders such as anorexia nervosa and bulimia.

Symptoms:
The symptoms of feeding disorders can vary, but common symptoms include:

•Refusing food
•Lack of appetite
•Colic
•Crying before or after food
•Failing to gain weight normally
•Regurgitating or vomiting
•Diarrhoea
•Abdominal pain
•Constipation
•Behavioural problems

Diagnosis :
Between 25% and 35% of normal children experience minor feeding problems. In infants born prematurely, 40% to 70% experience some type of feeding problem. For a child to be diagnosed with feeding disorder of infancy or early childhood, the disorder must be severe enough to affect growth for a significant period of time. Generally, growth failure is considered to be below the fifth percentile of weight and height.

Feeding disorder of infancy or early childhood is diagnosed if all four of the following criteria are present:

•Failure to eat adequately over one month or more, with resultant weight loss or failure to gain weight.
•Inadequate eating and lack of growth not explained by any general medical or physiological condition, such as gastrointestinal problems, nervous system abnormalities, or anatomical deformations.
•The feeding disorder cannot be better explained by lack of food or by another mental disorder, such as rumination disorder.
•The inadequate eating and weight loss or failure to gain weight occurs before the age of six years. If feeding behavior or weight gain improves when another person feeds and cares for the child, the existence of a true feeding disorder, rather than some underlying medical condition, is more likely.

Treatments :-
Successful treatment of feeding disorders requires a multidisciplinary team approach to assess the child’s needs and to provide recommendations and education to improve feeding skills, behavior, and nutrient intake. The multidisciplinary team for treatment of feeding disorders in childhood usually includes physicians specializing in problems of the gastrointestinal tract or of the ear, nose, and throat; a dietitian, a psychologist , a speech pathologist, and an occupational therapist. Support from social workers and physicians in related areas of medicine is also helpful.

An initial evaluation should focus on feeding history, including detailed information on type and timing of food intake, feeding position, meal duration, energy and nutrient intake, and behavioral and parental factors that influence the feeding experience. Actual observation of a feeding session can give valuable insight into the cause of the feeding disorder and appropriate treatments. A medical examination should also be conducted to rule out any potential medical problems or physical causes of the feeding disorder.

After a thorough history is taken and assessment completed, dietary and behavioral therapy is started. The goal of diet therapy is to gradually increase energy and nutrient intake as tolerated by the child to allow for catch up growth. Depending on the diet history, energy and nutrient content of the diet may be kept lower initially to avoid vomiting and diarrhea. As the infant or child is able to tolerate more food, energy and nutrient intake is gradually increased over a period of one to two weeks, or more. Eventually, the diet should provide about 50% more than normal nutritional needs of infants or children of similar age and size.

Behavioral therapy can help the parent and child overcome conditioned feeding problems and food aversions. Parents must be educated to recognize their child’s hunger and satiety cues accurately and to promote a pleasant, positive feeding environment. Changing the texture of foods, the pace and timing of feedings, the position of the body, and even feeding utensils can help the child overcome aversions to eating. If poverty, abuse, or parental mental illness contribute to the feeding disorder, these issues must also be addressed.

Prognosis :-
If left untreated, infants and children with feeding disorders can have permanent physical, mental, and behavioral damage. However, most children with feeding disorders show significant improvements after treatment, particularly if the child and parent receive intensive nutritional, psychological, and social intervention.

Prevention :-
Providing balanced, age-appropriate foods at regular intervals—for example, three meals and two or three snacks daily for toddlers—can help to establish healthy eating patterns. If a child is allowed to fill up on soft drinks, juice, chips, or other snacks prior to meals, appetite for other, more nutritious foods will decrease.

Positive infant and childhood feeding experiences require the child to communicate hunger and satiety effectively and the parent or caregiver to interpret these signals accurately. This set of events requires a nurturing environment and an attentive, caring adult. Efforts should be made to establish feeding as a positive, pleasant experience. Further, forcing a child to eat or punishing a child for not eating should be avoided.

Toolkit Helps Parents Recognize a Child’s Risk of Obesity

[amazon_link asins=’384170249X,3838110420,B00CE3B096,0309161797,B01NAG9FQK,B0015068PA,B01N2WDZY4,B00Y3NR0A8′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’765f8b7c-0e22-11e8-98ca-e93021148730′]

Some simple interventions used by pediatricians were enough to change a parent’s perspective about a child’s being overweight or obese, and change the parent’s behaviors at home to reduce those risks.
..
Researchers confirmed previous reports that parents of overweight or obese children do not recognize their child’s weight problem. But this time, by arming pediatricians with a “toolkit,” an easily used chart and a series of questions and suggestions, the researchers addressed several problems.

“Doctors often don’t have time to discuss overweight; they don’t have the tools to do it; and many aren’t confident that they’re going to make a difference in their patients’ lives,” said Eliana Perrin, lead author of the study.

“Also, parents don’t recognize weight problems or don’t know how to make things better, and even if they do, there are often barriers to healthier eating or more activity for these families,” says Perrin.

As First Lady Michelle Obama‘s “Let’s Move!” campaign aims to reduce childhood obesity – almost one-third of young people are overweight – two leading questions are how to affect that change and if it can be successful.

Perrin’s study is likely the first evidence that a parent’s assessment of their child’s weight can be changed. Her study also showed improved dietary behaviors in children and reduced time playing video games or watching television, called “screen time.”

“We found something we can do to help stem the obesity epidemic,” says Perrin, whose previous research in childhood obesity has shown that using a body mass index, or BMI, chart color-coded like a traffic light helps parents understand the often confounding measurement.

Perrin’s research group trained pediatric resident physicians on how to use the color-coded BMI chart and a revision of a questionnaire called “Starting the Conversation,” originally designed by Alice Ammerman, a co-author on the study. The STC gives health care providers a snapshot of potential red flags to help counsel patients as well as tips to implement change.

Parents were asked about their children’s weight status and discussions about weight in the doctor’s office. The Starting the Conversation form used in this study was revised by Perrin and asked parents about non-healthy eating habits – frequency of sugary snacks, sugar-sweetened beverages and eating out at restaurants, as well as activity and screen time. It also asked about the parent’s readiness to change. The pediatrics residents were instructed to show parents their children’s weight status in a color-coded BMI chart and were taught to use the parents’ responses to the questionnaire to engage the parents in discussions about healthier eating behaviors and activities.

Researchers enrolled 115 children ages 4 to 12 who were covered by Medicaid or the State Health Insurance Program and repeated the Starting the Conversation questionnaire as well as questions about weight status at one-month and three-month follow-up appointments.

The study showed the most significant improvement in dietary changes among children who were overweight. At follow up, they were more likely than healthy-weight children to drink lower-fat milk and showed the largest reduction in the frequency of eating out. But overall, children improved fruit and vegetable consumption, decreased sweetened beverages and unhealthy snacks, drank lower-fat milk more and reduced screen time.

In the initial visit, all of the parents of healthy-weight children accurately perceived their child’s weight. However, only 57 percent of overweight children’s parents did so at baseline. That improved significantly to 74 percent at three month follow up.

BMI was measured and tracked and a few children became more overweight, while more reached healthier weights but no significant improvements in weight status were noted in this short study, Perrin says. “The research has to be replicated and expanded, and it must determine if improvements in parental perception of children’s weight motivates families to improve behavior and, ultimately, leads to healthier weight over time,” she says.

“Everyone’s talking about BMI and we have a lot of studies to show that parents do not see their overweight children as overweight. That often does not sink in with parents,” Perrin says. “This is the first time we’ve seen a changed perspective from parents. We hope that parents who know their children are overweight will be empowered to help them achieve healthier lifestyles that can last a lifetime.”

Lymphoma

Definition:
The most common type of lymphoma is called Hodgkin’s disease. All other lymphomas are grouped together and are called non-Hodgkin’s lymphomas...CLICK & SEE

The lymphatic system is part of the body’s immune defense system. Its job is to help fight diseases and infection.

The lymphatic system includes a network of thin tubes that branch, like blood vessels, into tissues throughout the body. Lymphatic vessels carry lymph, a colorless watery fluid that contains infection-fighting cells called lymphocytes. Along this network of vessels are groups of small, bean-shaped organs called lymph nodes. Clusters of lymph nodes are found in the underarms, groin, neck, chest, and abdomen.

Other parts of the lymphatic system are the spleen, thymus, tonsils, and bone marrow. Lymphatic tissue also is found in other parts of the body, including the stomach, intestines, and skin.

Non-Hodgkin’s lymphoma, also called non-Hodgkin lymphoma, is cancer that originates in your lymphatic system, the disease-fighting network spread throughout your body. In non-Hodgkin’s lymphoma, tumors develop from lymphocytes — a type of white blood cell.

Non-Hodgkin’s lymphoma is more common than the other general type of lymphoma — Hodgkin’s disease.

Many different subtypes of non-Hodgkin’s lymphoma exist. The most common non-Hodgkin’s lymphoma subtypes include diffuse large B-cell lymphoma and follicular lymphoma.

Within normal lymph nodes there are microscopic clusters (follicles) of specialized lymphocytes. In some malignant lymphomas, the lymphocytes arrange themselves in a similar pattern that is called follicular or nodular. Small cell and follicular lymphomas typically have a chronic course with an average survival of 6 to 12 years. In the more aggressive lymphomas, the normal appearance of the lymph node is lost by diffuse involvement of tumor cells, which are usually moderate-sized or large.

Hodgkin’s disease, the most common lymphoma, has special characteristics that distinguish it from the others. Often it is identified by the presence of a unique cell, called the Reed-Sternberg cell, in lymphatic tissue that has been surgically removed for biopsy.

Hodgkin’s disease tends to follow a more predictable pattern of spread, and its spread is generally more limited than that of the non-Hodgkin’s lymphomas. By contrast, the non-Hodgkin’s lymphomas are more likely to begin in extranodal sites (organs other than the lymph nodes, like the liver and bones).

There are about ten different types of Non-Hodgkin’s lymphoma. Some types spread more quickly than others. The type is determined by how the cells look under a microscope (histology). The histologies are grouped together, based on how quickly they spread, into low-grade, intermediate-grade, or high-grade lymphomas.

Symptoms :
The most common symptom of non-Hodgkin’s lymphomas is a painless swelling in the lymph nodes of the neck, underarm, or groin. Other symptoms may include fevers, night sweats, tiredness, weight loss, itching, and reddened patches on the skin. Sometimes there is nausea, vomiting, or abdominal pain.

Symptoms of non-Hodgkin’s lymphoma may include:

*Swollen lymph nodes in your neck, armpit or groin
*Abdominal pain or swelling
*Chest pain, coughing or trouble breathing
*Fatigue
*Fever
*Night sweats
*Weight loss

As lymphomas progress, the body is less able to fight infection. These symptoms are not sure signs of cancer, however. They also may be caused by many common illnesses, such as the flu or other infections. But it is important to see a doctor if any of these symptoms lasts longer than 2 weeks.

Causes:
The cause of most lymphoma is unknown. Some occur in individuals taking drugs to suppress their immune system.

Non-Hodgkin’s lymphoma occurs when your body produces too many abnormal lymphocytes — a type of white blood cell.
Normally, lymphocytes go through a predictable life cycle. Old lymphocytes die, and your body creates new ones to replace them. In non-Hodgkin’s lymphoma, your lymphocytes don’t die, but continue to grow and divide. This oversupply of lymphocytes crowds into your lymph nodes, causing them to swell.

B cells and T cells

There are two types of lymphocytes, and non-Hodgkin’s lymphoma usually involves one or the other.

*B cells. B cells fight infection by producing antibodies that neutralize foreign invaders. Most non-Hodgkin’s lymphoma arises from B cells.

*T cells.
T cells are involved in killing foreign invaders directly. Non-Hodgkin’s lymphoma occurs less often in T cells.
Whether your non-Hodgkin’s lymphoma arises from your B cells or T cells helps to determine your treatment options.

Risk factors:
In most cases, people diagnosed with non-Hodgkin’s lymphoma don’t have any obvious risk factors, and many people who have risk factors for the disease never develop it. Some factors that may increase the risk of non-Hodgkin’s lymphoma include:

*Medications that suppress your immune system. If you’ve had an organ transplant, you’re more susceptible because immunosuppressive therapy has reduced your body’s ability to fight off new illnesses.

*Infection with certain viruses and bacteria
. Certain viral and bacterial infections appear to increase the risk of non-Hodgkin’s lymphoma. Viruses linked to increased non-Hodgkin’s lymphoma risk include HIV, hepatitis C virus and Epstein-Barr virus. Bacteria linked to an increased risk of non-Hodgkin’s lymphoma include the ulcer-causing Helicobacter pylori.

*Chemicals.
Certain chemicals, such as those used to kill insects and weeds, may increase your risk of developing non-Hodgkin’s lymphoma. More research is needed to understand the possible link between pesticides and the development of non-Hodgkin’s lymphoma.

*Older age.
Non-Hodgkin’s lymphoma can occur at any age, but the risk increases with age. It’s most common in people in their 60s or older.

Diagnosis:

Tests and procedures used to diagnose non-Hodgkin’s lymphoma include:

*Physical examination. Your doctor may conduct a physical exam to determine the size and condition of your lymph nodes and to find out whether your liver and spleen are enlarged.

*Blood and urine tests. Swollen lymph nodes are common and most often signal that your body is fighting an infection. Blood and urine tests may help rule out an infection or other disease.

*Imaging tests. An X-ray or computerized tomography (CT) scan of your chest, neck, abdomen and pelvis may detect the presence and size of tumors. Magnetic resonance imaging (MRI) scans can help your doctor determine whether your brain and spinal cord are affected. Doctors also use positron emission tomography (PET) scanning to detect non-Hodgkin’s lymphoma. Imaging tests can help determine the stage of your lymphoma.

*Removing a sample of lymph node tissue for testing.
Your doctor may recommend a biopsy procedure to sample or remove a lymph node for testing. Analyzing lymph node tissue in a laboratory may reveal whether you have non-Hodgkin’s lymphoma and, if so, which type.

*Looking for cancer cells in your bone marrow.
To find out whether the disease has spread, your doctor may request a biopsy of your bone marrow. This involves inserting a needle into your pelvic bone to obtain a sample of bone marrow.

Determining your type of non-Hodgkin’s lymphoma

Doctors classify non-Hodgkin’s lymphoma into many different types. Several methods for classifying types of non-Hodgkin’s lymphoma exist. Each method uses different combinations of factors, including:

*Whether your cancer involves B cells or T cells

*How the cells appear when examined using a microscope

*Specific genetic changes within the cancer cells

*Which antigens are present on the surface of the cancer cells

Doctors also assign a stage (I through IV) to the disease, based on the number of tumors and how widely the tumors have spread.

Treatment:
Treatment isn’t always necessary
If your lymphoma appears to be slow growing (indolent), a wait-and-see approach may be an option. Indolent lymphomas that don’t cause signs and symptoms may not require treatment for years.

Delaying treatment doesn’t mean you’ll be on your own. Your doctor will likely schedule regular checkups every few months to monitor your condition and ensure that your cancer isn’t advancing.

Treatment for lymphoma that causes signs and symptoms
If your non-Hodgkin’s lymphoma is aggressive or causes signs and symptoms, your doctor may recommend treatment.

Treatment planning takes into account the type of lymphoma, the stage of disease, whether it is likely to grow slowly or rapidly, and the general health and age of the patient. Common treatment options for several types are as follows:

Low Grade

Low-grade lymphomas include small lymphocytic, follicular small cleaved, and follicular mixed cell. For low-grade lymphomas, which usually grow very slowly and cause few symptoms, the doctor may wait until the disease shows signs of spreading before starting treatment.

Although low-grade lymphomas grow slowly and respond readily to chemotherapy, they almost invariably return and are generally regarded as incurable. The long-term outcome has not been favorably affected by the use of intermediate chemotherapy. Single agent or combination chemotherapy or radiation therapy may be required when the disease progresses or begins to cause symptoms.

Intermediate and High Grades
Intermediate grade includes follicular large cell, diffuse small cleaved, diffuse mixed cell, and diffuse large cell. The chance of recovery and choice of treatment depend on the stage of the cancer, age, and overall condition. Whatever the origin, the features that best predict the prognosis and guide decisions about therapy are the size, shape and pattern of the lymphocytes as seen microscopically.

Intermediate- and high-grade lymphomas are curable. Treatment for intermediate- or high-grade lymphomas usually involves chemotherapy, with or without radiation therapy. In addition, surgery may be needed to remove a large tumor.

Combination chemotherapy is almost always necessary for successful treatment. Chemotherapy alone, or abbreviated chemotherapy and radiation, cure 70 to 80 percent of patients with limited   intermediate-grade lymphoma. Advanced  disease can be eradicated in about 50 percent of patients.

Hodgkin’s Disease
The usual treatment for most patients with early stage Hodgkin’s disease is high-energy radiation of the lymph nodes. Research has shown that radiation therapy to large areas at high doses (3,500 to 4,500 rads) is more effective in preventing relapse than radiation of the diseased nodes alone.

Combination chemotherapy also is effective in the treatment of early stage Hodgkin’s disease. In addition, chemotherapy is the treatment of choice for advanced (stages III and IV) Hodgkin’s disease and for patients who have relapsed after radiotherapy. Drugs and radiation are sometimes given together, mainly in treating patients with tumors in the chest or abdomen.

Coping and support:
A diagnosis of cancer can be overwhelming. With time you’ll find ways to cope with the distress and uncertainty of cancer. Until then, you may find it helps to:

*Learn everything you want to know about your cancer
. Find out everything you need to know about your cancer in order to help you make treatment decisions. Ask your doctor for the type and stage of your cancer, as well as your treatment options and their side effects. Ask your doctor where you can go for more information. Good places to start include the National Cancer Institute and the Leukemia & Lymphoma Society.

*Build a strong support system. Having a support system of close friends and family may help you cope. Though you may feel tempted to keep to yourself, be open with your loved ones. Friends will ask you if there’s anything they can do to help you. Think of requests ahead of time, such as preparing meals or just being there to talk.

*Connect with other cancer survivors.
Sometimes you’ll feel as if your friends and family can’t understand what you’re going through. In these cases, other cancer survivors can offer support and practical information. You may also find you develop deep and lasting bonds with people who are going through the same things you are. Ask your doctor about support groups in your area. Or go online to Internet message boards, such as those offered by the Leukemia & Lymphoma Society.

*Set reasonable goals. Having goals helps you feel in control and can give you a sense of purpose. But don’t choose goals you can’t possibly reach. You may not be able to work a 40-hour week, for example, but you may be able to work at least part time. In fact, many people find that continuing to work can be helpful.

*Take time for yourself. Eating well, relaxing and getting enough rest can help combat the stress and fatigue of cancer. Also, plan ahead for when you may need to rest more or limit what you do.

*Stay active. Receiving a diagnosis of cancer doesn’t mean you have to stop doing the things you enjoy or normally do. For the most part, if you feel well enough to do something, go ahead and do it. Stay involved as much as you can.

*Look for a connection to something beyond yourself.
Having a strong faith or a sense of something greater than yourself may help you cope with having cancer. It may also help you maintain a more positive attitude as you face the challenge of cancer.
