Kidney Stones

Kidney Stones
If I have a Kidney stone when should I call a doctor?
If you have a kidney stone, you may already know how painful it can be. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not just go away. It may even get larger. Your doctor can help.
You should call a doctor when you have:
extreme pain in your back or side that will not go away
blood in your urine
fever and chills
vomiting
urine that smells bad or looks cloudy
a burning feeling when you urinate
These may be signs of a kidney stone that needs a doctor's care.
What is a kidney stone?
A kidney stone is a solid piece of material that forms in the kidney out of substances in the urine. A stone may stay in the kidney or break loose and travel down the urinary tract. A small stone may pass all the way out of the body without causing too much pain. A larger stone may get stuck in a ureter, the bladder, or the urethra. A problem stone can block the flow of urine and cause great pain.
Are all kidney stones the same ?
No. There are four major types of kidney stones.
The most common type of stone contains calcium (KAL-see-um). Calcium is a normal part of a healthy diet. The calcium that stays behind joins with other waste products to form a stone.
A struvite (STROO-vite) stone may form after an infection in the urinary system. These stones contain the mineral magnesium (mag-NEE-zee-um) and the waste product ammonia (uh-MOH-nyuh).
A uric (YOOR-ik) acid stone may form when there is too much acid in the urine. If you tend to form uric acid stones, you may need to cut back on the amount of meat you eat.
Cystine (SIS-teen) stones are rare. Cystine is one of the building blocks that make up muscles, nerves, and other parts of the body. Cystine can build up in the urine to form a stone. The disease that causes cystine stones runs in families.
What do kidney stones look like?
Kidney stones may be as small as a grain of sand or as large as a pearl. Some stones are even as big as golf balls. Stones may be smooth or jagged. They are usually yellow or brown.
What can my doctor do about kidney stones?
If you have a stone that will not pass by itself, your doctor may need to take steps to get rid of it. In the past, the only way to remove a problem stone was through surgery.
Now, doctors have new ways to remove problem stones. The following sections describe a few of these methods.

Cosmetic Surgery

Cosmetic Surgery
Cosmetic surgery is now more popular that ever with reality TV shows such as extreme makeover increasing public awareness about cosmetic surgery and plastic surgery procedures. Although in the past cosmetic surgery was only availble to the rich and famous, it is now becoming popular amongst the general public.
The Medic8 guide to cosmetic surgery aims to provide a comprehensive non-biased overview of cosmetic and plastic surgery procedures, the benefits, the risks involved and what you could expect from the cosmetic surgery procedure that you are intrested in.
What is Cosmetic Surgery?
Cosmetic surgery involves having a surgical procedure carried out by a plastic/cosmetic surgeon to improve the "look" of a particular part of your body. Cosmetic surgery can not only improve physical appearance but it can also have emotional and psychological effects. Procedures such as breast enlargement or a facelift could have a great influence on an individual's self esteem and confidence levels.
Cosmetic Surgery has its risks
As with any surgical procedures there are risks involved and it is important that before undergoing any cosmetic surgery procedures that you are fully aware of all the potential risks and potential side effects and discuss these with your surgeon.

Otitis Media (Ear Infection)

Otitis Media (Ear Infection)
What is otitis media?
Otitis media is an infection or inflammation of the middle ear. This inflammation often begins when infections that cause sore throats, colds, or other respiratory or breathing problems spread to the middle ear. These can be viral or bacterial infections. Seventy-five percent of children experience at least one episode of otitis media by their third birthday. Almost half of these children will have three or more ear infections during their first 3 years. Although otitis media is primarily a disease of infants and young children, it can also affect adults.
Are there different types of otitis media?
Yes. There are two main types. The first type is called acute otitis media (AOM). This means that parts of the ear are infected and swollen. It also means that fluid and mucus are trapped inside the ear. AOM can be painful.
The second type is called otitis media with effusion (fluid), or OME. This means fluid and mucus stay trapped in the ear after the infection is over. OME makes it harder for the ear to fight new infections. This fluid can also affect your child's hearing.
How does otitis media happen?
Otitis media usually happens when viruses and/or bacteria get inside the ear and cause an infection. It often happens as a result of another illness, such as a cold. If your child gets sick, it might affect his or her ears.
It is harder for children to fight illness than it is for adults, so children develop ear infections more often. Some researchers believe that other factors, such as being around cigarette smoke, can contribute to ear infections.
Why are more children affected by otitis media than adults?
There are many reasons why children are more likely to suffer from otitis media than adults. First, children have more trouble fighting infections. This is because their immune systems are still developing. Another reason has to do with the child's eustachian tube. The eustachian tube is a small passageway that connects the upper part of the throat to the middle ear. It is shorter and straighter in the child than in the adult. It can contribute to otitis media in several ways.
The eustachian tube is usually closed but opens regularly to ventilate or replenish the air in the middle ear. This tube also equalizes middle ear air pressure in response to air pressure changes in the environment. However, a eustachian tube that is blocked by swelling of its lining or plugged with mucus from a cold or for some other reason cannot open to ventilate the middle ear. The lack of ventilation may allow fluid from the tissue that lines the middle ear to accumulate. If the eustachian tube remains plugged, the fluid cannot drain and begins to collect in the normally air-filled middle ear.
One more factor that makes children more susceptible to otitis media is that adenoids in children are larger than they are in adults. Adenoids are composed largely of cells (lymphocytes) that help fight infections. They are positioned in the back of the upper part of the throat near the eustachian tubes. Enlarged adenoids can, because of their size, interfere with the eustachian tube opening. In addition, adenoids may themselves become infected, and the infection may spread into the eustachian tubes.
Bacteria reach the middle ear through the lining or the passageway of the eustachian tube and can then produce infection, which causes swelling of the lining of the middle ear, blocking of the eustachian tube, and migration of white cells from the bloodstream to help fight the infection. In this process the white cells accumulate, often killing bacteria and dying themselves, leading to the formation of pus, a thick yellowish-white fluid in the middle ear. As the fluid increases, the child may have trouble hearing because the eardrum and middle ear bones are unable to move as freely as they should. As the infection worsens, many children also experience severe ear pain. Too much fluid in the ear can put pressure on the eardrum and eventually tear it.

ASTHMA IN CHILDHOOD

Asthma is one of the commonest chronic medical conditions to affect children and it has been affecting an increasing number of children in the past 10 years.
Children with asthma, like adults with asthma, should see a doctor for treatment of their asthma. Treatment may include allergy testing, finding ways to limit contact with things that bring on asthma attacks, and taking medicine.
Young children will need help from their parents and other caregivers to keep their asthma under control. Older children can learn to care for themselves and follow their asthma self-management plan with less supervision.
Asthma medicines for children are like those adults use, but doses are smaller. Children with asthma may need both a quick-relief (or "rescue") inhaler for attacks and daily medicine to control their asthma. Children with moderate or severe asthma should learn to use a peak flow meter to help keep their asthma under control. Using a peak flow meter can be very helpful because children often have a hard time describing their symptoms.
Parents should be alert for possible signs of asthma in children, such as coughing at night, frequent colds, wheezing, or other signs of breathing problems. If you suspect that your child has asthma or that your child's asthma is not well controlled, take your child to a doctor for an exam and testing.
Your doctor will choose medicines for your child based on the child's symptoms and test results. If your child has asthma, you will need to go to the doctor for regular followup visits and to make sure that your child uses the medicines properly.
