ADHD, or attention deficit hyperactivity disorder to give it its proper name, is a behavioral disorder which affects approximately ten percent of school age kids. What is interesting is that it actually affects about three times as many boys as it does girls, but as of yet nobody is quite sure why this happens to be the case.

Children that have ADHD are usually hyperactive, do not focus well and normally act without thinking it through first. Although as a rule they understand the things that are expected of them, they find it difficult to carry this out as they are unable to pay attention, sit still or focus on details.

ADHD Attention Deficit Hyperactivity Disorder

As everyone is probably aware though, most children, especially the younger ones, act like this frequently, especially if they are excited, but ADHD affected kids are different as such because the symptoms last over a long period of times and can be triggered be a variety of reasons, not just excitement or anxiety. ADHD can hinder the ability of a child to function properly at school, at home or when they are out and about.

Although difficult to diagnose, ADHD can be managed with the proper treatment and the children affected can learn to manage their symptoms successfully.

Tuberculosis is a condition which primarily affects the lungs.  The bacteria which cause tuberculosis are slow moving bacteria and a person who has been infected might not have any symptoms for months or years afterwards.  The infection can spread to other parts of the body such as the nervous system or the bones.  Symptoms of tuberculosis include a cough that won’t go away, night sweats and weight loss but most of the time the immune system will kill off the bacteria and there will be no symptoms.  Sometimes, if the immune system cannot kill the bacteria it will build up a defense to the infection and it will stay in the body but no symptoms will be experienced, however, sometimes the body just cannot fight the bacteria and the infection spreads to the lungs and becomes known as active tuberculosis.  It can happen that in cases where the infection has lain dormant in the body in can become active at a later date.

Tuberculosis

Tuberculosis was a major disease many years ago and resulted in many deaths, but the introduction of antibiotics and vaccinations helped to reduce this.  In recent years though, tuberculosis cases have been increasing again, especially in ethnic minorities who have come from areas where tuberculosis is still widespread. Areas where the disease is widespread include countries of Africa south of the Sahara desert, Eastern Europe, Central America, South East Asia, and Russia.

If tuberculosis is not treated it can be deadly as it can result in the person not being able to breath properly. Treatment with antibiotics for tuberculosis usually involves taking a course for at least six months.

Hepatitis B is a virus that affects the liver. It is more prevalent in Asia and Africa and can be either acute (more common), resolving itself relatively quickly with no long term liver damage, or chronic (in about 20% of cases) lasting six months or more, and sometimes even for life with symptoms coming and going randomly.

Hepatitis B is normally transmitted via contact with infected bodily fluids or blood and only a very small amount of blood is required to transmit the disease because it is that infectious. In the developed world the virus is normally spread via sharing of contaminated needles, unprotected sex and the sharing such things as razor blades. In less developed countries where blood products are not screened properly or medical equipment is not sterilized adequately, this can also lead to the spread of the virus.

Hepatitis B viruses have an incubation period of between six weeks and six months, but approximately one third of all cases show no symptoms of the disease at all. In another third of cases, symptoms appear flu-like in nature and can include aches, pains and weakness; fever; headaches; loss of appetite; jaundice; diarrhea; and, vomiting and nausea. In the last third of cases, the virus can cause severe illness that can last for a long time (many months in some cases).

Vaccines are available nowadays against hepatitis B, but treatment for those infected normally includes nothing more than rest and recuperation. Drug treatments may be required for chronic types of the disease, to prevent damage to the liver and other parts of the body.
