Tuberculosis disease patients are affected by a bacterial attack on the body. Most commonly this attack affects the lungs, although it is capable of invading any area of the body. In the past, this condition was known as consumption because patients would gradually waste away without proper treatment. After a patient has become infected, the bacteria multiply within the lungs, causing pneumonia. The lymph nodes are also affected and are generally inflamed. From this beginning, tuberculosis can easily spread to other areas. Patients who have weakened immune systems, such as the elderly population or diabetics, are more prone to contraction of the disease.

Specifically, the bacteria that most frequently is the cause of the disease is Mycobacterium tuberculosis. However, other bacterial organisms can be the source. Variations of the disease that are caused by these other bacteria are known as atypical tuberculosis and are potentially more serious than the regular disease. Tuberculosis patients typically acquire the disease by inhalation of infected sputum ejected by other tuberculosis patients when they sneeze, cough, shout, or spit. It is not possible to contract the disease only by contact. The infected air must be inhaled to become infected. One rare atypical tuberculosis is caused by the consumption of unpasteurized milk. Tuberculosis symptoms can take many months to appear after infection, but are most commonly manifested as fatigue, fever, night sweating, and weight loss. As the condition gets more pronounced, tuberculosis symptoms can worsen to include chest pain, difficulty breathing, and coughing blood or other material. Additionally, as the infection spreads to other parts of the body, more symptoms can occur.

In areas of the world where tuberculosis is more prevalent, the use of a vaccine is common to help children and infants avoid the disease. After contraction, some patients do not need any additional tuberculosis treatment as their immune systems are capable of dealing with the disease by surrounding infected areas with scar tissue. For patients who have inhaled the bacteria but do not have active symptoms, antibiotics will be used to control the infection. The most frequently used antibiotic is isoniazid. Taken for a period of half a year to a year, it will prevent the tuberculosis from becoming active. Tuberculosis treatment for patients who are already exhibiting active signs will be done with administration of a combination of medications in addition to isoniazid. The period of treatment can last several years until the infection is fully under control. In rare and severe cases, surgery on the lungs can help a patient recover when medication options have failed.

Although tuberculosis has been greatly reduced in many parts of the world, the infections still have the potential to be very dangerous. Advances in medicine, coupled with a general improved sense of sanitary conditions, have contributed to controlling the number of deaths related to tuberculosis disease.

To understand how best to treat an infection or disease, a patient should be aware of the viral and bacterial pathogenesis that is manifested in the condition. These complications can be as minor as a common cold or as serious as AIDS. Pathogenesis comes from the Greek words pathos and genesis and literally translates as the creation of a disease. The bacterial and viral pathogenesis starts with an introduction of the invader to human host cells. The pathogens then use the cell’s reproduction abilities to grow and spread to various parts of the human body. If the body’s natural defense mechanisms and induced defenses are unable to control and eliminate the foreign organism, then the results could be infections or disease. The resulting complication is entirely dependent on which strain of virus or bacteria has infected the host cells.

The causes are also quite different with various strains of invaders. A weakened immune system or essential vitamin deficiency can be an easy target for infection, but the virus pathogenesis for many species does not need even this reduced suppression to be effective. In many cases all that is needed is direct contact with the foreign organism to begin the replication process. This could include being close to an infected person when they sneeze or transmit bodily fluids. These infected fluids can be transferred to common surfaces and sent to new hosts when they touch the same surfaces. While some viruses and bacteria are able to survive airborne, the majority need to be transferred by fluids or carrier organisms such as mosquitoes. While the symptoms experienced by viral pathogenesis can vary depending on the specific foreign organism, the most common symptoms are those caused by the body’s attempt to fight the infection. These symptoms include nasal congestion or drainage, throat irritation, coughing, sneezing, fevers, headaches, and vocal hoarseness.

The best treatment method is obviously prevention. If a person is around someone that clearly exhibits symptoms of bacterial or viral infection, care should be taken to avoid the spread of bodily fluids. In addition, hands need to be washed frequently when in contact with infected people. Many antibacterial products exist to eliminate bacteria from the hands. A patient who is infected should take care to cover the mouth when sneezing and coughing. This will also help limit the spread of the virus or bacteria. Lastly, common areas should be kept clean to avoid bodily fluids that could remain on unwashed surfaces. Once a person is infected, a visit to a local physician or clinic is in order to determine the root cause of the complication and the best treatment options to combat it. For most bacterial invaders, antibiotics are available to aid in recovery. Treatment of viruses can be very different, but may include antiviral medications, vaccines, or simply letting the immune system take care of the infection.

The process of bacteria and virus pathogenesis can lead to difficult complications, but being aware of the process of infection and taking preventative measures can aid in a patient remaining healthy. As always, if complications arise or the infection is persistent, a doctor should be consulted to deal with the viral or bacterial pathogenesis.

Infections resulting from the hepatitis virus are a common cause of liver inflammation. It is expected that one in every twenty people will contract hepatitis at some point in their lives. The infection is classified into three main categories: hepatitis a, b, and c. There does exist a hepatitis d, e, and f, but these variations are much rarer. Hepatitis A is most commonly found in developing countries due to its proliferation in areas with poor sanitation. In western populations, most cases of this type of infection result from travel to these developing countries. Hepatitis a does not cause permanent liver damage. Hepatitis b, on the other hand, does cause permanent liver damage and can progress to cirrhosis and cause death. A third of the world’s population is thought to be infected. Spread by blood to blood contact, hepatitis c affects 300 million people worldwide.

However, these viral infections are not the only cause of hepatitis. It can also be caused by prolonged alcohol consumption as well. Symptoms of hepatitis a usually appear as soon as two weeks after infection and can appear in the following forms: fatigue, abdominal pain, diarrhea, depression, weight loss, fever, nausea, loss of appetite, jaundice, and dark urine or light stools. Hepatitis B has primarily the same set of outward manifestations. For many victims of both types of infection, it is quite possible for the disease to go undetected as it can be asymptomatic. Most people who have contracted acute hepatitis c display no symptoms and for those who do, the signs are relatively minor. If a patient has been infected with hepatitis c for over six months, they are rediagnosed as having chronic hepatitis c. The symptoms for this variation can differ wildly between patients, but commonly include the above signs as well as itching, insomnia, unusual bleeding or bruising, and enlarged veins.

Hepatitis a has no treatment, but infected patients should get plenty of rest and water and avoid high fat foods and alcohol consumption. Acute hepatitis b cases do not often need and form of treatment because full developed immune systems are capable of dealing with the infection without outside help or interference. However, chronic hepatitis b should be treated to prevent the disease from worsening into cirrhosis or cancer of the liver. While no medications are capable of completely eradicating chronic hepatitis b, many antiviral drugs can stop the infection from spreading. A hepatitis vaccine can be used to combat both a and b varieties provided it has been caught soon enough. In hepatitis c patients, medical intervention is almost always required. Twenty percent of cases that do not receive hepatitis treatment result in death. Most commonly, a regimen of medications is taken to stop the growth of the virus. In addition to drugs, many new treatment options have been discovered. One such new method is the Hemopurifier, a device which eliminates infectious viruses directly from the bloodstream. There is no hepatitis vaccine for the c variation.

If a patient feels that they have contracted hepatitus, a local physician should be alerted immediately. The doctor will run tests to deterine the specific type of infection and the best course of hepatitis treatment. Hepatitis virus complications can range from minute to severe, therefore early detection of the disease is of paramount importance.

Chronic pancreatitis is a medical disorder where there is chronic inflammation of the pancreas. The pancreas is a long thin organ lying just behind the stomach. Its function is to release important enzymes that can process foods and also secret insulin which regulates blood sugar. The pancreas is a very fragile organ and can easily get traumatized. When the pancreas secretions of enzymes are blocked by a gall stone or the organ is damaged by certain drugs or alcohol, it spills the enzymes in the vicinity which then start to digest the pancreas itself. Acute pancreatitis is a common medical disorder and can present itself with severe pain, nausea and vomiting. However, when the pancreas has been subject to insults from alcohol and drugs for a long time, chronic pancreatic results.

The typical features of pancreatitis include upper abdominal pain which may radiate to the back, difficulty processing foods, loss of weight, indigestion and frequent episodes of diarrhea. The stools appear oily and tend to float on water- primarily because they contain fat which has not been processed. In most cases of chronic pancreatitis pain, there is also severe nausea and vomiting. The other feature of chronic pancreatitis pain is that soreness is continuous and unrelenting.

Pancreatitis has many causes including alcoholism, gall stones surgery, medications, cystic fibrosis, high levels of fat, infection, and smoking. In pancreatitis the organ is severely damaged and no longer makes enzymes to process food. Thus these individuals typically develop diabetes, malnutrition and are at a risk of developing pancreatic cancer.

The diagnosis of pancreatitis involves the use of some blood and stool test, and Ct scans of the abdomen. Chronic pancreatitis treatment is quite difficult disorder and not satisfactory in most individuals. These individuals are frequently in and out of the hospital, chiefly because of the severe pain. Chronic pancreatitis treatment chiefly involves pain control. Pain management may involve nerve blocks, use of potent narcotics and use of pain pumps. Most individual are given pancreas enzyme supplements to help the body process food and increase absorption of nutrients. Enzymes are available in pill form. A visit to the dietitian may also help so one can eat foods that will not promote diarrhea or indigestion. In some cases the pain is unbearable and surgery may be the only option. There are various techniques of doing pancreatic surgery but it is best to visit a surgeon who specializes in treating this organ.

All individual who have pancreatitis should undertake lifestyle changes to prevent pain attacks. These include avoidance of alcohol and discontinuing smoking, eating a low fat diet and drink lots of water.
There are a variety of health supplements that have been touted to treat pancreatitis but there is no medical evidence to prove that. If you are interested in trying these alternative health supplements, talk to your physician first- most are more harmful than the chronic pancreatitis itself.

A chronic infection usually means that an infection has been present for a long time or keeps on recurring. In general, long standing infections develop after an acute infection. Acute infections usually last a few days but prolonged infections can last several weeks or even months. In rare cases, one may not even be aware of the occult infection and thus continue to transmit it to others.

Worldwide, infections claim millions of lives each year. The chief reason is due to unsanitary living conditions and poor hygiene. The sad truth is that the majority of these infections can be prevented by implementing preventive care measures. An infection is chronic in medical terms when an individual has the following symptoms:

- Persistent fatigue lasting 3 months or more
- Weight loss
- Low grade fever
- Decreased white cell count
- Night sweats and chills
- mild to moderate pain

A prime example of a recurrent infection is hepatitis C and AIDS. Both these disorders usually have no symptoms in the early stages and yet the individual remains infectious. Once acquired, HIV cannot be cured and it is considered to be a long standing infection because the virus remains in the body for years. Hepatitis C similarly can be acquired from sexual intercourse, blood transfusions or sharing of infected needles. The diagnosis of hepatitis and AIDS are usually only made after a blood test. In most cases of hepatitis C, the majority of individuals go on to become chronic carriers of the virus. Moreover, signs and symptoms of liver damage or even cancer may not appear for 15- 20 years after the infection is acquired.

Other more common recurrent infections include ear infections in children, tuberculosis, herpes simplex, Lyme disease and hepatitis B. With recurrent infections, the organism continues to damage the body and then causes repeated symptoms. Eventually long standing infections weaken the immune system and the individual becomes symptomatic. This manifests as weight loss and extreme malaise.

The diagnosis of a long standing infection can be difficult as the symptoms are not specific. In any case, if an infection is suspected, blood cultures, chest x-rays or stool analysis are usually the first steps taken. Depending on the individual and cause, chronic infection treatment may require hospitalization and use of intravenous antibiotics. In most cases of chronic infection treatment, one tries to improve the nutritional status and adopt changes in lifestyle. Since infections can cause serious damage to the body, recovery can be long and protracted. Besides the infection, one also has to treat the complications and increase energy level.

The best way to avoid chronic infection is to adopt healthy life styles, eating good nutritious food, exercise on a regular basis, avoid tobacco and limiting alcohol intake.
