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.

Obesity occurs when excess weight causes health problems.  People with obesity usually have a BMI or Body Mass Index greater than 30.  Weight gain is usually caused when energy (calorie) intake is more than calories burnt.  There are many risks for people with obesity as it can contribute to an increase in a variety of diseases such as heart disease, high blood pressure, diabetes, and some forms of cancer.  Some people are more prone to weight gain than others and this can be down to genes, however, most people find that obesity is a factor of lifestyle and eating behaviors.

Many people eat when they are depressed, lonely, anxious, stressed or just when they are bored.  Obesity is also linked to a lack of physical exercise.  In today’s day there seems to be more and more examples of children showing signs of obesity at an alarmingly young age.  Schools, parents and government organizations seem to be recognizing the need to encourage children to eat more healthily and to support exercise programs.

Obesity

There is a higher amount of processed, cheaper foods available on the market today which are higher in sugar, salt, and fat which contributes to the increase in obesity levels among young people.  Coupled with the trend for video games and increased numbers of TV channels it is no surprise that more and more young people are being diagnosed with obesity every day.

Diet and exercise are the most important factors when preventing obesity.  In order to lose weight people need to reduce daily calories and partake in at least 20 – 30 minutes of exercise daily.  Increased fruit and vegetables can help to feel full and reduce the chance of reaching for sugary foods which contain more fat.

The testicles are found within the scrotum which is a loose sac of skin hanging down behind the penis.  The function of the testicles is to produce sperm and the male sex hormone testosterone.  Most of the time any lumps or swelling within the testicles are benign but it is natural for people to worry when they have found a lump.

Testicular torsion results in swelling of the testicles if the testicle has become twisted.  This interrupts blood flow and causes a large tender distension.  It often happens in developing boys who are experiencing puberty but has also been know to happen in men in their 20’s although it is quite rare.  Testicular torsion is a medical emergency due to the fact that it needs to be rectified by surgery within 6 hours or there is a risk that the testicle will be lost.

Symptoms of testicular torsion include nausea; vomiting; swelling of the scrotum; fever; abdominal pain; the need to urinate often; and, excruciating pain in one testicle.  The cause of testicular torsion results from a spermatic cord that is too long.  The spermatic cord is where the testicles hang from and in some boys this cord is too long leading to increased movement of the testicle which means the cord becoming twisted.  If it twists too much it will cut off the blood supply and the testicle will die.  Testicular torsion can sometimes just happen for no reason at all or it can be the result of strenuous exercise or other physical activity.

An ultrasound scan can be done to confirm suspicion of testicular torsion. Surgery needs to take place almost immediately to save the testicle.  The surgeon will have to cut the scrotum and untwist the cord.  He will then sew the cord to the scrotum to prevent this happening again.
