Cat scratch disease is an infectious disease, which came after a cat scratch (which caused a skin lesion), manifested by painful regional lymphadenopathy and persistent (may persist for weeks or months). If the infection disseminates, the patient will present generalized adenopathy, often confused with leukemia disease situation. The symptoms of cat scratch disease is initiated by inoculation of B. henselae bacilli. Since cat is not a natural reservoir for pathogenic species B. quitana, there is clear evidence of the involvement of bacteria in the development of cat scratch disease.

More than half of cases of disease occur in childhood. Risk of infection increases significantly when children are exposed to contact with cats shows asymptomatic bacterium, or are infested with fleas. Usually, bacteria are inoculated through a wound caused by broken, and in rare cases the bite or saliva of cats. Disease incidence increased dramatically in the warm months of the year when fleas develop an intense activity of parasite. Flea plays a significant role in pathogen transmission from a sick to a healthy cat. There is insufficient evidence attesting to human host disease transmitted through flea bites.

-Clinical symptoms of cat scratch disease
Average incubation period of the disease is more than five days. Scratch at the patient shows a popular lesion that later will turn into a pustule (vesicular lesions filled with pus), covered with scabs. At 7 days after pathogen inoculation, regional lymph nodes will be large in volume and become sensitive to touch. After a week of evolving, papulous may resolve spontaneously.

Frequently, solutions of continuity (wounds) caused by scratch it locates the upper limbs and face. The patient may develop simultaneously, a new bacterial infection with staphylococci and other skin pathogens. Regional lymph nodes can increase the discharge volume. Usually the patient has fever, but may present variable systemic symptoms: weight loss, anorexia (lack of appetite) and malaise. If a treatment will be set up quickly, adenopathy can persist for several months and can be confused with adenopathy in leukemia (lymphatic malignant diseases).

Other events occurring in immune-competent patients: encephalitis, convulsions, coma (especially in children), meningitis, myelitis, hepatitis, osteomyelitis and septicemia. If the pathogen is inoculated by conjunctive, the individual will present painful conjunctivitis and preauricular adenopathy.

-Pathology
On anatomic-pathologic examination, the affected tissue will present lesions characteristic of granulomatous inflammation accompanied by necrosis starry. Angiogenesis lesions are absent. Thus, depending on the host's immune status, bacillus B. henselae, infectious diseases can cause two distinct cat-scratch disease and bacillary angiomatosy skin.

-Diagnosis
Cat scratch disease may be suspected when a patient tells the recent history of contact with a potentially sick cat, skin lesions (scratches upper limbs and the face), and adenopathy sensitive to touch, will strengthen the clinical suspicion. Positive diagnosis is confirmed by results of histopathological examination of regional lymph nodes increase the volume. Warthin-Starry stain allows the observation of unit’s pathogen on the optical microscope. Serological tests used to identify antibodies have a sensitivity of 80%. Polymerase chain reaction (PCR) can identify the 16S ribosomal RNA genes of the species B. henselae. It had tried making crops using biological material from the affected nodes, spinal cerebrospinal fluid or other tissues, but they rarely were positive for B. henselae.

Cat scratch disease is a clinical entity transmitted to humans through inoculation (scratches, stings, and bites) and characterized by skin lesions of primary inoculation site, accompanied by fever and regional adena. Etiology of this disease is still unknown, although it is believed to be caused by a microorganism belonging to the Chlamydia group, but know that it is transmitted through various contacts with infected cat. This disease is ubiquitous, yet rarely diagnosed, although most cases occur in small epidemics family (children and teenagers being the most exposed) mainly in autumn and winter.

Instead of inoculation by a cat scratch or sting occurs after 7-14 days of incubation, a red swelling, itching, which is 48 hours into a vesicle, pustule and then in 90% of cases. Soon, it is broken, leaving a small crust which eliminates a few days, but even if the primary effect is very small or absent, it is possible that, after another few days to produce swollen lymph nodes in the region injured, resulting a manifest adenopathy in 20-25% of cases, fever (38-39 degrees C), chills, headache, anorexia, nausea, abdominal pain and vomiting, accompanied by skin eruptions. Fortunately, such complications are rare, the symptoms of cat scratch disease having generally a benign, but they must avoid the appearance, logically, avoiding contact with infected cats.

Also, other problem regarding animals, it’s their bites. Cat bites are much rarer than dog bites, but very dangerous, because half of the cases recorded have led to serious and very serious infections. Poured cat teeth are very sharp, deep wound penetrate a soft tissues, thus generating an increased risk of osteomyelitis and septic arthritis (risk greater than if a dog bites). Hands are the most vulnerable areas of cat bites. Most patients with cat bites, which appear in the guard room, are female (adult or children). Usually the bites affect hands and arms in equal proportions of patients.
Bite wounds, but scratches and cat shows increased risk of infections caused by microorganisms contained in the saliva of that animal.

Most of the infections caused by cat bites are due to pathogen P. multocida, Gram-negative bacteria, the smallest, which normally colonize oropharyngeal house cats.
Generating bacteria infections occurring through cat bites, is generally mixed. A number of pathogens inoculated via cat bites are similar to those that cause infections if dog bites. Risk of infection increases considerably when the affected individual has a background that lead to pathology of the body’s depressing regarding the immune system.

Pasteurella species pathogen inoculation will lead to an outbreak inflammatory progressing rapidly (within a few hours), generating signs of severe inflammation (local pain, redness, swelling the area) and abundant purulent secretions. Pasteurella species spread pathogens from an animal carrier with aerosol drops can cause bacterium or pneumonia, human host.

Through the bite of cat, rabies or tetanus can be transmitted. Bartonella henselae bacteria inoculation will generate late appearance of "cat scratch” disease. Also, tularemia can occur after cat bites, being a symptom of cat scratch disease.

Lyme disease is a bacterial infection that is transmitted by the tick bite. Symptoms of Lymes disease most shells encountered are fever, fatigue, headache and eritem. Because these symptoms are encountered in many other diseases, must be done before a differential examination to diagnose.Isodex scapularis, the deer tick or black is the vector tick infectious bacterium Borrelia burgdorferi. It is responsible for Lyme illness. It normally lives in mice, squirrels and other small animals.

Tick hasthree developmental stages: larva, nymph and adult. When an infected tick feeds on blood of a sick animal, and ingests the bacteria it will live in the intestine. These ticks and the next meal will infect another animal or human. Most cases of infection occur in late spring or summer when the tiny tick nymphs are most active in the environment and human activities are frequent. The rest, live in the fur deer ticks, which do not get sick from Lyme disease. Treatment for symptoms of Lymes disease is with antibiotics.

-Causes:
The deer tick is the principal vector of Lyme disease but has not been demonstrated whether other ticks may or may not become vectors.
Other modes of disease transmission:

-People contacts;

-Transmission during pregnancy;

-Blood transfusions;

-Animals.

Interpersonal transmission: not yet proved that the disease could transmit and through kissing, touching, sex with an infected person.
Disease during pregnancy can lead to infection in the placenta and abortion have not yet registered negative effects on the fetus if the mother is treated properly with her  pointed antibiotics .No disease transmission yet through breast feeding.

Although there were no recorded cases of infection by another blood transfusion, it was found infecting the bacteria survive in blood stored for donations. The patients can donate 12 months after the last dose of antibiotic treatment.
Pets can do Lyme disease but no evidence that they may become vectors for the human body, instead they bring ticks into the house and garden.
Disease is not transmitted through the squirrel or deer meat, but it should still cook to appropriate temperatures.

-Symptoms of Lyme disease
The first sign of infection is usually a circular called migratory erythema. It occurs in 70-80% of infected people and begins to tick sting area after a period of three to thirty of days. A distinguishing feature of redness is expanding gradually over several days; reaching up to 30 cm. Erythema may become normal colored center as it expands as compared with ox-eye. Can be hot and painful. Some people develop other flushes in different areas over several days.
Other symptoms of Lyme disease:

-Fatigue;

-Chills;

-Fever;

-Headache;

-Cramps;

-Lymphadenopathy.

In some cases, redness may be missing.

Left untreated, the infection spreads to other parts of the body in a few weeks, cause a variety of symptoms:

-Motor weakness of both sides of the face, Bell's Palsy;

-Serious headache and neck stiffness due to meningitis;

-Poseur-sore  which causes insomnia;

-Throb and dizziness due to arrhythmia;

-Migration of joint-pain.

Most symptoms resolve even without treatment. After months of infection, 60% of patients will have intermittent arthritis with severe joint pain and swelling, the knees were especially affected. Other 5 percent will develop neurological chronic pain states, tingling, decreased ability to concentrate and short-term memory. Most patients respond to   treatment, if it's initiated early in disease, a small percentage will have symptoms after years: muscle pain, arthritis, tiredness, insomnia, cognitive disabilities.

To prevent Lyme disease, if possible avoid contact with soil, leaves and vegetation, especially in May, June and July when ticks are not yet mature and are hardly noticed.
When you’re going for an outdoor adventure, follow the advice from the following lines:

• Wear shoes or dark boots, long sleeve shirts and long pants. Put your pants into boots to prevent ticks you get on your feet.

• Wear light colored clothes to see ticks easily.

• If you have long hair, keep it tight and covered with a cap or a scarf to protect it even more

• When you are outdoors, do not sit on the ground.
• When you are outdoors often look at your child and you do not have ticks.

• Wash all clothes after leaving the areas infested with ticks, bathe and shampoo your child's hair carefully to remove any ticks that have not seen.

• Insecticides that contain DEET (read the instructions to see if they are N, N-diethyl-meta-toluamida) can help in destroying ticks. Choose an insecticide DEET concentration between 10% and 30 for preventing symptoms of Lymes disease. Generally, DEET should not be applied more often than once a day and is not recommended for babies under two months. DEET be used on exposed skin, and clothes, socks and shoes, but not applied on the face, under clothes, or hands of small children.

Ticks can pick any area of the body, but rather some areas as:

• The area behind the ears;

• The back of the neck;

• the underarm area;
• Groins area;

• The area behind the knee.
If you find a tick on the child, tell the doctor, who can ask to keep the tick after a note from the child's body (one can put a jar of alcohol to kill it). Use tweezers to grab the tick close to the head or mouth, skin around the child. Pull firmly and steadily until tick off, and then wipe with alcohol the sting place.
Myths about ways to be killed ticks (using gas or a lit match), are abundant, but it is better not to try them - these methods do not work.

You can avoid penetration of ticks in your home and keeping the lawn cut and clipped lawns, cleaning the bushes, dry leaves and grass, storing firewood away from the ground. In addition, you can use a professional spray containing insecticide in the garden in May and September to prevent ticks multiplication.
-When you go to the doctor
If the child is a target-shaped rash or other symptoms of Lymes disease - swollen lymph nodes near the site of tick sting, body aches, headache or fever - go to the doctor immediately.

-Complications of Lyme disease
The last stage of Lyme disease can occur if the disease has not been detected early and treated properly. Symptoms of Lymes disease in the last stage can occur weeks or years after the sting that the infection and include arthritis, especially in knees and later deterioration of cognitive functions in adults.

-Lyme disease contagious - Lyme disease is not transmitted from person to person. Risk of Lyme disease depends on each person's exposure to ticks. Children and adults who spend time outdoors - especially in forested areas or near them - have a higher risk of contracting Lyme disease.

-Lyme disease and pregnancy-In rare cases, Lyme disease contracted during pregnancy can be transmitted to the fetus. If you're pregnant and you are concerned about this, ask your doctor.

-Household pets? Domestic animals such as dogs and cats can become infected with Lyme disease bacteria and may carry infected ticks into areas inhabited by people. If you have a dog or cat, talk to vet about products and protection measures that you can apply for your pet.


-How are Lyme disease diagnoses? -Lyme disease is the hallmark of hives circular-shaped target. Usually, as hives are very distinct, a person has can be diagnosed immediately with Lyme disease and blood tests are not necessary. Because urticaria may disappear quickly, consider the idea to photograph any suspicious rash on your baby's skin if you can not go to the doctor immediately.  In some cases, hives appear in the form of target. Without it, doctors must rely on other symptoms and the likelihood of exposure assessment of a person to an infected tick. Blood tests can help diagnose Lyme disease by detecting antibodies to Borrelia burgdorferi in the patient's blood.

However, blood tests can give inaccurate results if they are made one month after initial infection, because training lasts to antibodies. Lyme disease can be difficult to diagnose because symptoms can resemble many other diseases. Your doctor can help you decide if you need to do child analysis to detect Lyme disease. (Test: an ELISA for detecting IgM and IgG antibody to Borrelia burgdorferi, confirmed by Western blot test)

-Treating symptoms of Lymes disease
Lyme disease detected early usually means a diet of antibiotics administered for 3-4 weeks.  If it’s quickly diagnosticated and is treated with antibiotics, Lyme disease on children is almost always treatable. Hives usually disappear within a few days after beginning treatment, but other signs and symptoms may persist for several weeks.

-Preventing Lyme disease
Ticks usually live in the soil shaded, moist and often cling to the grass, the bushes, shrubs and low branches of trees. Lawns and gardens may harbor ticks, especially at the edges of forests and around old stone walls (areas where deer and mice live, the primary hosts of ticks).

Lyme disease is an infection caused by the bacterium Borrelia burgdorferi, that’s the reason for why the disease is called the tick bite disease or Lyme. This bacterium is usually seen in animals such as mice and deer. Ixodes ticks can carry the bacteria when biting an infected animal, then one can transmit to humans, which can be Lyme disease. In the following lines, you'll find out more things about Lyme's disease, about symptoms of Lymes disease, but, more important, you'll find out how you can protect against this disease. 

-Who is the agent of Lyme disease spread?
Ticks! Ticks live in grass and shrubs and attach an animal passing near them, called the host. Ticks are small and can be hard to see with the naked eye. Young ticks, or nymphs, are the size of poppy seeds.

-Signs and symptoms of Lymes disease:
Lyme disease can affect the skin, joints, nervous system and other systems or organs. Symptoms and their severity vary from person to person. Symptoms of Lyme disease are often described in three separate stages of the disease, although not all patients pass through all stages:

• The first sign of infection is usually a circular rash called erythema migration, which occurs 1-2 weeks after infection but can occur within 30 days after tick bite. This rash often has a characteristic target appearance with a central red dot surrounded an area of clean skin, in turn surrounded by a red zone that extends. May appear as a solid red ring extending. Area may be warm to the touch and usually is not painful, not so itchy. Hives shaped target may be more difficult to observe in people who have darker skin, which may look like a bruising. Hives usually go in about a month. Although this rash is considered typical of Lyme disease, there are many patients who do not present this symptom of Lyme disease.

• Together with the hives, the infected person may have flu-like symptoms as swollen lymph nodes, fatigue, headache and muscle aches.  If it’s left untreated, initial symptoms may go away. But on some people, infection can spread to other parts of the body. At this stage of Lyme disease, symptoms usually appear within weeks after the tick bite, even in people who have had hives page. Some persons may feel very tired and very bad, or have hives in several areas, different on sting place.

Lyme disease can affect the heart, which can lead to irregular heartbeat or chest pain. Can spread to the nervous system, causing facial paralysis (Bell's palsy) or tingling and numbness of the arms and legs. May start to cause headache and stiff neck that can be considered symptoms of meningitis. Swelling and pain may occur in the larger joints of the body.

• Ciclosporin. This powerful drug that is commonly used to treat fistulas related to Crohn's disease symptoms is reserved for patients who do not respond well to other drugs - but has significant potential side effects.
-Antibiotics for Crohn's disease symptoms:

-Metronidazole. Until recently the most widely used antibiotic for Crohn's disease, metronidazole can sometimes cause serious side effects, including numbness in hands and feet, and occasional muscle pain or weakness.

-Ciprofloxacin. This drug, which eases the symptoms of patients with Crohn's disease is now generally preferred to metronidazole. Ciprofloxacin may cause fainting, cardiac arrhythmias, abdominal pain, diarrhea and fatigue.

-Other drugs:
In addition to controlling inflammation, certain medications may help relieve symptoms. Depending on the severity of Crohn's disease, your doctor may recommend one or more of the following: Anti-diarrhea, laxatives, analgesics, iron supplements, injections of vitamin B-12

-Surgery: If diet and lifestyle changes, drug therapy or other treatments will ease symptoms, your doctor may recommend surgery to remove the damaged portion of the digestive tract or to close fistulas and remove scar tissue. No surgical cure for Crohn's disease. In the best case, surgery can give you several years of remission. In the worst case, can give temporary improvement in symptoms. Even with the removal of all diseased parts of the intestine, inflammation recur frequently in previously healthy portions of the intestine after months or years after surgery. Therefore, surgery in Crohn's disease is primarily used for:

1. Removal of sick segment of small intestine that causes obstruction.

2. Pus draining from the abdominal and peri-rectal abscess.

3. Treatment of severe anal fistulas does not respond to drugs.

4. Resection of internal fistulas (such as fistula between colon and bladder) that can cause infections.

-Personal Care: Diet

• Limit consumption of lactate products. Like many people with inflammatory bowel disease, you may find that problems such as diarrhea, abdominal pain and flatulence shrinks when narrow or eliminate lactate products. You could be lactose intolerant - which mean you can not digest sugar (lactose) found in lactate products. If so, try to replace milk with yogurt or cheese with small amount of lactose, for example schweizer or cheddar. You can also use a helper enzyme to dissolve the lactose. In some cases, you have yet to completely remove lactose. If you need help, call a dietitian to make a healthy diet with low content of lactose.

• Try to eat no fat, fiber, and difficult detour food, beans, cabbage and broccoli, fresh fruit juice and fruit - especially citrus fruits - spicy food, popcorn, alcohol, caffeine, foods and drinks that contain caffeine as example chocolate and fizzy drinks. Eat small amounts, drink plenty of fluids, and try multivitamins.

-Stress:  Although no cause Crohn's disease, stress can worsen symptoms and trigger seizures. Regular exercise, yoga, massage or meditation, progressive relaxation exercises, deep breathing, hypnosis can help.

-Crohn briefly:

• Crohn's disease is an inflammatory bowel disease.

• The cause of Crohn's disease is unknown.

• Crohn's disease can cause ulcers in the small intestine, colon, or both.

• Abdominal pain, diarrhea, vomiting, fever, weight loss are symptoms of Crohn's disease.

• Crohn's disease can cause small bowel obstruction.

• Crohn's disease may be associated with red and painful nodules that appear on the skin, and swollen joints, spine, eyes and liver.

• Diagnosis of Crohn's disease is the administration of barium enema, barium radiography of the small intestine, and colonoscopy.

• The choice Crohn's disease treatment depends on the location and severity.

• Crohn's disease treatment includes medications to reduce inflammation and immune suppression, antibiotics and surgery.

Other important types of analyses related to Chron's disease are the following ones:

• barium radiography. This analysis allows the doctor to assess the large intestine using radiography. Before analysis, place of barium, this is a chemical contrast in the intestines. Sometimes he can add air. When barium is administered through the rectum, can obtain images of the colon and terminal ileum site. With Barium radiography may show ulcerations, narrowing, and sometimes bowel fistulas.

• Radiography intestine. This analysis examines the portion of the intestine which can not be seen at colonoscopy. You will drink barium and through the radiography, the doctor will see your intestine. This analysis can locate narrowed and inflamed areas that can be seen in the small intestine in Crohn's disease or when the physician has difficulty in determining the type of inflammatory disease that you have.

• computed tomography (CT). CT can sometimes use a special radiographic technique that provides more details than traditional radiography. This analysis visualizes the entire bowel and tissues outside it, which can be seen in other tests. Can help detect abscesses.

-Treatment for Crohn's disease symptoms:

There are no medicines to cure Crohn's disease. Crohn's disease symptoms and severity vary between patients. Patients with medium or mild symptoms not requiring treatment. Patients whose disease is in remission (symptoms are absent) may also not require treatment.

-Drug therapy: Purposes of medical treatment is to reduce inflammation that causes symptoms. In the best case, this can lead not only to alleviate the symptoms but also the long-term remission. Treatment for Crohn's disease usually includes drug therapy and in some cases, surgery.

To treat symptoms, the doctor may recommend anti-diarrhea, laxatives or painkillers. It is important to talk to your doctor before taking any medicine that is given without prescription.

Doctors use several categories of anti-inflammatory drugs that work differently. Drugs that are good for patients may not be suitable for others, so it may take up to find medicine that will help. In addition, because some medications have side effects significant enough, you will need to weigh risks and benefits of each treatment.

-Anti-inflammatory drugs: Inflammatory drugs are often the first step in treating Crohn's disease. They include:

• sulfasalazine

• Mesalamina

• Corticosteroids. Steroids can help reduce inflammation anywhere in your body, but have many side effects, including swelling of face, excessive facial hair, night sweats, insomnia and hyperactivity. More serious side effects include hypertension, type II diabetes, osteoporosis, fractures, cataracts and increased risk of contracting infections. Long-term use of steroids in children can lead to slow growth.

-Suppressor of the immune system: These drugs reduce inflammation, but instead work on the immune system to treat inflammation.

• Azathioprina and mercaptopurine. They are most commonly used immunosuppressive treatment of inflammatory bowel disease. Although it may take up to three months to become effective, they help reduce symptoms of inflammatory bowel diseases in general and can heal fistulas caused by Crohn's disease in particular.

• A shortage of red blood cells (anemia). Some patients with Crohn's disease develop anemia because of low iron levels in the blood caused by bleeding stools or intestinal inflammation itself.

• Ulcers. Crohn's disease begins with small areas, scattered on the surface of the bowel. These areas evolves painful ulcers that penetrate deep - and sometimes Drill - bowel walls.

-Other symptoms:
Patients with severe Crohn's disease symptoms may have fever and fatigue, as well as other problems that occur outside the digestive tract, including arthritis, eye inflammation, skin diseases and liver inflammation or common bile duct channel.
-Risk Factors:

• Age. Crohn's disease can occur at any age but is more likely to do in youth. Most patients diagnosed with Crohn's disease are between 15 and 35 years;

• ethnic origin. Whites had the highest risk;

• Family history. Have a greater risk if a close relative, for example a parent, sibling or child has the disease. If a brother or sister has Crohn's disease, your risk of contracting the disease is 30 times higher than the general population;

• Where you live. If you live in an urban area or in an industrialized country, is more likely to contract Crohn's disease;

• Smoking.
-Factors that may cause exacerbation of Crohn's disease symptoms include:



• Medications

• Infections

• Hormonal changes

• Lifestyle changes, including increased stress

• Smoking.

-Diagnosis:
Crohn's disease is suspected in patients with fever, abdominal pain and uncomfortable sensations, diarrhea with or without bleeding and anal diseases.

To confirm the diagnosis, you may have to make the following analysis:

• blood analysis. The doctor might suggest blood tests to check for anemia or signs of infection.

• Colonoscopy. Direct visualization of the rectum and large intestine can be made flexible viewing tube (colonoscopy). Colonoscopy is more accurate than barium radiography in detecting small ulcers or small areas of inflammation of the colon and terminal ileum area. This is the most sensitive diagnostic test for Crohn's disease. It enables the doctor to see the entire colon using a thin tube, flexible lighting with a camera attached. During the procedure, your doctor may take a piece of tissue (biopsy) for laboratory analysis, which can help confirm the diagnosis. If there are groups of inflammatory cells called granulomas, for example, is likely to have Crohn's disease because granulomas do not occur in ulcerate colitis.



• flexible sigmoidoscopy. In this procedure, the doctor uses a thin tube, flexible lighting, to examine the sigmoid, the last half a meter of the colon. The analysis takes a few minutes. It is somewhat uncomfortable, and there is a risk colon wall penetration. May also not show and other problems that may exist above the colon or small intestine.

Crohn's disease is a chronic inflammation of the intestines. It mainly produces ulcerations (breaks in the mucosa) in the small intestine and the thick, but it also can affect the digestive system anywhere from the mouth to the anus. It is also called regional enteritis, granulomatous enteritis, colitis or terminal ileitis. Crohn's disease and ulcerate colitis are similar - so similar that often are taken as one another. Both inflame the lining of the digestive tract, and both can cause severe episodes of watery diarrhea and abdominal pain or bleeding.  Ulcerate colitis leading to colonic inflammation (colitis) and / or rectum (Proctor), Crohn's disease can cause inflammation of the colon, rectum, small intestine (jejunum and ileum), and occasionally stomach, mouth and esophagus.

Ulcerate colitis, on the other hand, usually affects only the internal lining of the large intestine (colon) and rectum.

-What are the causes?  The causes of Crohn's disease are unknown. Studies show that this, and other intestinal inflammatory diseases, are an abnormal response of the immune system to bacteria normally found in the intestine, and not normally produce this disease.

Bacteria and viruses that cause diseases (pathogens) may also play a role in the development of Crohn's disease. Immune activation in the intestine appears to play an important role. The immune system is composed of immune cells and proteins that they produce. Normally, these cells and proteins protect and attack the body against bacteria, viruses, fungi and other foreign invaders. Activation of the immune system produces tissue inflammation which it occurs. (Inflammation is an important mechanism of defense used by the immune system).

-What are the Crohn's disease symptoms?

Find in the following lines, the main Crohn's disease symptoms:

• Pain and cramping. Pain is often described as intermittent and stomach cramps can be painful to touch. Abdominal pain can become dull and constant as the disease progresses.

• Blood in the stool. Foods that progresses through the digestive tract can cause inflamed tissue and intestinal bleeding can also bleed. Can see traces of bright red blood in the toilet, or darker blood mixed in stool. Bleeding can occur and that you can not see (occult). In phase severe, bleeding is often massive and continuous.

• Diarrhea. Some patients may have diarrhea 10 to 20 times per day. They can wake up at night with the need to go to the bathroom. Crohn's disease can cause bleeding in the stool, but not always.

• Loss of appetite.

• Fever. In severe cases, may develop fever or other symptoms that affect the whole body. High fever may mean that you have complications involving infection, for example an abscess.


• Losing weight. Recurrent symptoms, for example diarrhea, can lead to weight loss.
