Conjunctivitis, or pink eye as it is sometimes known as, is an inflammation that affects the outer lining of the eyes. The condition is caused by bacteria or virus’ but can also affect people due to allergies or exposure to certain chemicals. Anyone can catch conjunctivitis but those closest to a sufferer are more at risk of contracting it than others.

When someone has conjunctivitis, all the fluid in the infected individuals eyes are very contagious, therefore the condition can easily be spread from one person to another via contaminated fingers, towels or clothes and through items such as sunglasses and makeup.

Conjunctivitis

Symptoms of conjunctivitis include redness in the white areas of the eyes, a scratchy sensation in the eyes, swollen eyelids that often feel itchy and “heavy” feeling eyes full of tears. The symptoms usually occur from 24 to 72 hours after infection and can last for several days.

Treatment of the condition depends on the cause, but a severe or chronic cased should be referred to a physician immediately. Prevention of conjunctivitis is always the best cure, so washing hands frequently as well as keeping them away from the eyes, not sharing towels, flannels or handkerchiefs with anybody and using fresh paper toweling to wipe the eyes if necessary and then discarding straight away, are all things to do to help prevent the spread of the condition.

Swine flu is a disease that affects pigs and is a highly contagious type of respiratory disease caused by a version of the influenza A virus. Typically, swine flu is of the subtype designated as H1N1, and this is also the subtype that is currently affecting humans.

H1N1 Swine Flu Virus

Although swine flu normally affects pigs, it can sometimes jump to a different species, which is what has happened with humans. Symptoms of swine flu are, on the whole, very similar to normal seasonal influenza outbreaks in humans and can range between no symptoms at all or very mild symptoms, to severe and even fatal pneumonia. Because these symptoms are similar to the normal flu symptoms, swine flu is almost impossible to distinguish from normal flu, unless specifically looked for by a doctor.

Humans can catch swine flu either by contact with pigs that are infected, which is the most common way, and contact with humans that are infected, which is less common. For human to human infection to occur, very close contact needs to occur between the two parties.

Swine Flu Symptoms

The symptoms of swine flu in humans is very similar to normal influenza symptoms, as mentioned above, and these can be aches, chills, coughing, diarrhea, headache, sore throat, fever, fatigue and vomiting. Most previous cases of swine flu in humans has cleared up without any medical assistance, but there are a couple of drugs that are successful in treating the condition – adamantanes and inhibitors of influenza neuraminidase.

Down syndrome is a genetic disorder otherwise known as trisomy and it is where an individual has inherited an additional or extra copy of a particular chromosome. In the case of Down’s syndrome, the affected individuals have three copies rather than two of chromosome 21. The consequence of this additional copy is that it changes the balance of the body resulting in characteristic intellectual and physical features.

Down Syndrome

There are three kinds of Down’s syndrome: regular trisomy 21 which is where all the cells in the body have an extra chromosome 21 and is the most common type of the condition with nearly 94% affected with Down’s having it; translocation, which is where extra chromosome 21 material attaches to another chromosome, and four percent have this type; and mosaic, which is where only some of the cells have additional chromosome 21. This usually has milder features than the other two types and only two percent of affected individuals have mosaic.

Down syndrome sufferers look different to normal people and usually have a flat type of facial profile with eyes slanting upwards. Smaller ears, protruding tongue and a flat back of the head are other features. Individuals affected tend to be shorter than normal, have poor muscle tone and have broad, short hands. Half the affected individuals have a heart defect, which can be treated in some, but not others. Some have problems with their gut, making it difficult to eat while increasing the risk of constipation and thyroid problems.

There is no cure for Down syndrome but there are treatments available for the accompanying symptoms as well as support for the learning difficulties.
