Stomach Ulcers

What is a Stomach Ulcer?

A stomach ulcer (also called a peptic ulcer) is a small erosion (hole) in the gastrointestinal tract. The most common type, duodenal, occurs in the first 12 inches of small intestine beyond the stomach. Ulcers that form in the stomach are called gastric ulcers. An ulcer is not contagious orcancerous. Duodenal ulcers are almost always benign, while stomach ulcers may become malignant.

- Gastroenteritis Overview
  Gastroenteritis is a condition that causes irritation and inflammation of the stomach and intestines (the gastrointestinal tract). The most common symptoms are
  - diarrhea,
  - crampy abdominal pain,
  - nausea, and
  - vomiting.
  Many people also refer to gastroenteritis as "stomach flu." This can sometimes be confusing because influenza (flu) symptoms include
  - headache,
  - muscle aches and pains, and
  - respiratory symptoms, but influenza does not involve the gastrointestinal tract.
  The term stomach flu presumes a viral infection, even though there may be other causes of infection.
  Viral infections are the most common cause of gastroenteritis but bacteria, parasites, and food-borne illnesses (such as shellfish) can also be the offending agents. Many people who experience vomiting and diarrhea that develops from these types of infections or irritations think they have "food poisoning," when they actually may have a food-borne illness.
  Travelers to foreign countries may experience "traveler's diarrhea" from contaminated food and unclean water.
  The severity of infectious gastroenteritis depends on the immune system's ability to resist the infection. Electrolytes (these include essential elements of sodium and potassium) may be lost as the affected individual vomits and experiences diarrhea.
  Most people recover easily from a short episode of vomiting and diarrhea by drinking fluids and gradually progressing to a normal diet. But for others, such as infants and the elderly, loss of bodily fluid with gastroenteritis can causedehydration, which is a life-threatening illness unless the condition is treated and fluids restored.

Brain Tumor

The symptoms of brain tumors depend on their size and location in the brain.

FaceTumor

Face Tumor

The face contains your eyes, eyebrows, forehead, nose, cheeks, mouth, teeth and chin. To facilitate expression and movement, the face comprises a large network of nerves that supply energy to its numerous muscles.

Cold Fever

What is fever?

Fever is an increase in your body’s temperature to a range that is above normal (98.6 degrees Fahrenheit). Normal body temperature can change throughout the day by a few degrees. Various factors can increase your body temperature including eating, physical activity, medications, surrounding (room or outdoor) temperature, or a strong emotional response.

Brain cancer Symptoms: Do I have a brain cancer?

Brain cancer symptoms vary from patient to patient, and most of these symptoms can also be found in people who do NOT have brain cancers. Therefore, the only sure way to tell if you have a brain cancer or not is to see your doctor and get a brain scan.

Hiv/AIDS

HIV/AIDS

HIV/AIDS Symptoms and Signs

Many people with HIV do not know they are infected.

Many people do not develop symptoms after they first get infected with HIV. Others have a flu-like illness within several days to weeks after exposure to the virus. They complain of fever, headache, tiredness, and enlarged lymph nodes in the neck. These symptoms usually disappear on their own within a few weeks. After that, the person feels normal and has no symptoms. This asymptomatic phase often lasts for years.

The progression of disease varies widely among individuals. This state may last from a few months to more than 10 years.

During this period, the virus continues to multiply actively and infects and kills the cells of the immune system.
The virus destroys the cells that are the primary infection fighters, a type of white blood cell called CD4 cells.
Even though the person has no symptoms, he or she is contagious and can pass HIV to others through the routes listed above.

AIDS is the later stage of HIV infection, when the body begins losing its ability to fight infections. Once the CD4 cell count falls low enough, an infected person is said to have AIDS. Sometimes, the diagnosis of AIDS is made because the person has unusual infections or cancers that show how weak the immune system is.

The infections that happen with AIDS are called opportunistic infections because they take advantage of the opportunity to infect a weakened host. The infections include (but are not limited to)

pneumonia caused by Pneumocystis, which causes wheezing;
brain infection with toxoplasmosis which can cause trouble thinking or symptoms that mimic a stroke;
widespread infection with a bacteria called MAC (mycobacterium avium complex) which can cause fever and weight loss;
yeast infection of the swallowing tube (esophagus) which causes pain with swallowing;
widespread diseases with certain fungi like histoplasmosis, which can cause fever, cough, anemia, and other problems.

A weakened immune system can also lead to other unusual conditions:

lymphoma in (a form of cancer of the lymphoid tissue) the brain, which can cause fever and trouble thinking;
a cancer of the soft tissues called Kaposi's sarcoma, which causes brown, reddish, or purple spots that develop on the skin or in the mouth

Tetnus texoid

Tetanus is infection of the nervous system with the potentially deadly bacteria Clostridium tetani (C. tetani).

Tuberculosis

Tuberculosis Symptoms

You may not notice any symptoms of illness until the disease is quite advanced. Even then the symptoms -- loss of weight, loss of energy, poor appetite, fever, a productive cough, and night sweats -- might easily be blamed on another disease.

Only about 10% of people infected with M. tuberculosis ever develop tuberculosis disease. Many of those who suffer TB do so in the first few years following infection, but the bacillus may lie dormant in the body for decades.
Although most initial infections have no symptoms and people overcome them, they may develop fever, dry cough, and abnormalities that may be seen on a chest X-ray.

This is called primary pulmonary tuberculosis.
Pulmonary tuberculosis frequently goes away by itself, but in 50%-60% of cases, the disease can return.

Tuberculous pleuritis may occur in 10% of people who have the lung disease from tuberculosis.

The pleural disease occurs from the rupture of a diseased area into the pleural space, the space between the lung and the lining of the abdominal cavity.
These people have a nonproductive cough, chest pain, and fever. The disease may go away and then come back at a later date.

In a minority of people with weakened immune systems, TB bacteria may spread through their blood to various parts of the body.

This is called miliary tuberculosis and produces fever, weakness, loss of appetite, and weight loss.
Cough and difficulty breathing are less common.

Generally, return of dormant tuberculosis infection occurs in the upper lungs. Symptoms include

common cough with a progressive increase in production of mucus and
coughing up blood.
Other symptoms include the following:

fever,
loss of appetite,
weight loss, and
night sweats.

About 15% of people may develop tuberculosis in an organ other than their lungs. About 25% of these people usually had known TB with inadequate treatment. The most common sites include the following:

lymph nodes,
genitourinary tract,
bone and joint sites,
meninges, and
the lining covering the outside of the gastrointestinal tract.

Maleria

The general symptoms include:

headache

nausea

fever

vomiting and

flu-like symptoms

These symptoms can vary depending on the type of plasmodium that caused the infection.

Time for symptoms to develop

Plasmodium falciparum normally take 7 to 14 days to show symptoms while Plasmodium vivax and ovale normally take 8 to 14 days (but in some cases can survive for some months in the human horst) and Plasmodium malariae 7 to 30 days.

These figures are as indication only - the onset of symptoms varies tremendously and people should not try and diagnose themselves by using any time-frame figures as these listed above.

Symptoms of malaria infection are not always dramatic, and can easily be dismissed as unimportant.

Should the infection not be attended to deterioration is normally sudden and drastic as the parasites rapidly increase in the blood stream.

Symptoms may appear and disappear in phases and may come and go at various time frames. These cyclic symptoms of malaria are caused by the life cycle of the parasites - as they develop, mature, reproduce and are once again released into the blood stream to infect even more blood and liver cells.

When this happens a high swinging fever can develop, with marked shivering and intense perspiration.

Further serious complication involving the kidneys and brain can then develop leading to delirium and coma.

There are cases reported where symptoms of malaria infection developed 12 months after the patient was bitten by a mosquito, as the plasmodia may remain dormant in the liver for a long period.

hepatitus C symptoms

hepatitus C

A minority of people have symptoms during the early acute phase of the infection. These symptoms typically develop 5-12 weeks after exposure to HCV. Some people describe the symptoms as beingflulike. The symptoms may last a few weeks or months.

hepatitus B

Welcome to this treatment guide for HIV-positive people who also have hepatitis B (HBV). This guide provides information on the prevention, care, and treatment of HBV, and the impact of HBV on HIV disease. It is designed to be accessible to people with no medical training. Where medical terms are used, they are explained in detailed but simple language.

hepatitus A

Symptoms

Symptoms will usually show up 2 - 6 weeks after being exposed to the hepatitis A virus. They are usually mild, but may last for up to several months, especially in adults.

Symptoms include:

Signs and tests

The doctor will perform a physical examination and may discover that you have an enlarged and tender liver.

Blood tests may show:

Raised IgM and IgG antibodies to hepatitis A (IgM is usually positive before IgG)
Elevated liver enzymes (liver function tests), especially transaminase enzyme levels

Treatment

There is no specific treatment for hepatitis A. Rest is recommended when the symptoms are most severe. People with acute hepatitis should avoid alcohol and any substances that are toxic to the liver, including acetaminophen (Tylenol).

Fatty foods may cause vomiting, because substances from the liver are needed to digest fats. Fatty foods are best avoided during the acute phase.

thelsemia

thelesemia

The thalassemias are a diverse group of genetic blood diseases. Thalassemia is the most common inherited single gene disorder in the world. Scientists and public health officials predict that thalassemia will become a worldwide issue in the next century. With global improvements in childhood disease prevention and treatment, more focus will be given to diagnosing disorders. It is our hope that by providing education about the disease we can raise awareness, encourage people to get tested for the trait, and spread knowledge about comprehensive treatment.
