Migraines are throbbing headaches that are normally very intense, occurring in just one half of the head. They can affect people of all ages and their cause is unknown. What is known is that during a migraine attack, blood vessels located in the brain dilate. This dilation causes the blood vessels to draw in on each other which stimulate the nerve endings near to these blood vessels. It is this that is thought to cause the pain.

Migraine

Migraines are fairly common occurrences, affecting nearly 20% of women and 6% of men during their lifetimes. Triggers for the migraine attack can vary, but some people are very aware that eating certain foods such as chocolates, cheese or citrus fruits can bring on an attack. Some other things that have been known to trigger migraines include anxiety, stress, exercise, loud noise, bright lights, traveling and the contraceptive pill. Many women appear to have attacks on or around the time of the menstrual periods.

When people describe migraines, they are commonly associated with headaches of varying degrees. These can include headaches occurring in bouts of approximately four to 72 hours; headaches on one side of the head; headaches throb and get worse with physical activity; nausea accompanied by vomiting; and other symptoms associated with sensitivity to light.

Migraines are treated by using painkillers. Which type depends on the severity and length of bouts being suffered.

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.

A condom is classed as a barrier contraceptive and its job is to block any sperm from fertilizing a female egg. Condoms can be made from latex, lambskin or polyurethane and are known to be approximately 98% effective at preventing pregnancy if used in the correct manner. It has to be pointed out that lambskin condoms have been around for a very, very long time but are still available; they are more expensive than conventionally made condoms and are not as good at preventing STD’s.

For efficient use of condoms, the penis must not touch the vagina before the condom has been applied. The reason for this is because a man does not necessarily need to ejaculate for any sperm to come from his penis; it can happen before as well. The best way to use a condom is to hold the bulb part between the figure and the thumb, ensuring it is the right way round. Make sure there isn’t any air trapped inside and then, while still holding the bulb, place the condom over the erect penis. Then it should be gently rolled down the shaft of the penis (if it doesn’t roll then it has been placed upside down). The condom should be disposed off immediately after ejaculation but before the penis becomes flaccid.

How to Use a Condom

The benefits of condom use include the fact that they are a reliable method to prevent pregnancy, there are very rarely any side effects from wearing one, a lowered chance of an STD transmission, they are easily available and they come in all shapes and sizes (and flavors nowadays).

Disadvantages of condom use include the fact that it can break during sex, they can tear while being taken out of the package and are not compatible with some lubricants.
