Around five years back most people were under the impression that it is safer to wear contact lenses in place of getting a laser surgery done. But this has changed over the years with the introduction of newer technology (as microkeratome is replaced by an eximer laser) as well as more informed and competent treatment being practiced.
Almost every one of the contact lens users has at one time or the other used them incorrectly leading to various eye infections. That is where Lasik comes as a solution to all your problems.

The patient is asked to stop using contact lenses a month before the surgery. This is done to help the cornea retain its natural shape.

Once you have settled on getting the surgery done your doctor will schedule an eye evaluation examination for you. Lasik vision correction can be done on most patients unless they have a history of a serious eye inflammation, such as uveitis or iritis or a case of severe eye dryness.

In the operating room, the doctor will use an antiseptic solution followed by a numbing solution which will help you relax. An instrument known as lid speculum is inserted in the eye to aid in keeping your eyes open throughout the procedure. After this a ring like device is inserted to hold the cornea in place. This instrument causes a sensation of pressure but no pain. Now with the help of an eximer laser a flap is cut into the tissue in front of your cornea. You will be made to stare at a light while the ophthalmologist carries out the surgery as this will keep your cornea fixed. After the surgery your eye will be covered for a few hours. This is an ambulatory procedure, you will need someone to assist you after the operation and drive you home since there is no need for an over-night stay at the hospital.

Are you tired of wearing glasses all day long? Do you hate the fact that you have to depend on an optical instrument to see the world clearly? Do your contact lenses irritate your eyes too often? Then laser eye surgery is the answer to all your problems. Lasik or LASIK stands for laser-assisted in situ keratomileusis and it is a refractive surgery which has become very popular in the recent years. This is owing to the fact that the success rate of this surgery is very high and clear vision is attained by the next day itself. In this procedure, the ophthalmologist will cut thin flap of the cornea using an instrument called microkeratome. With the help of an eximer laser, the surgeon now removes and restructures bits of the corneal tissue by ablation. In recent surgery, even the creating of the flap is done by lasers instead of the conventional microkeratome.
Lasik eye surgery works for people suffering from myopia, hypermetropia and astigmatism. One of the biggest advantages of Lasik eye surgery is that patients of most age groups can undergo this surgery unless there are signs of cataract in the patient, in which case the implantation of multifocal lenses is advised. Also, people with spectacle numbers from +6.0 to -14.0 can be treated upon by using this technology.

Lasik is also an ambulatory (same day) surgery. This means that it is not required for the patient to stay overnight at the hospital. Although it takes about 20 minutes to operate on each eye, good ophthalmologists prefer treating one eye at a time and only after receiving a satisfactory result do they proceed.

Peripheral Vascular Disease commonly called Peripheral Arterial Disease refers to obstruction of large arteries except those supplying the heart, head ,neck or brain.The basic abnormality is either a narrowing of the peripheral arteries as a result of any inflammatory process involving the vessels or there is a mechanical obstruction to the flow of blood distal to the site of obstruction. This may include Atherosclerosis,a condition in which an arterial wall thickens due to accumulations of fatty materials such as cholesterol, or it may be blockage of the artery by a blood clot called a thrombus or an embolus which is any intravascular mass detached from its origin and is capable of blocking an artery at a distant site.

Peripheral vascular disease is a term used commonly for the atherosclerotic blockage of arteries found in the lower extremities. There are a series of symptoms ,progressive as the disease advances leading to a disabling condition that is amputations usually if not intervened at a proper time. It starts as a mild pain while walking known as claudication caused by incomplete blood vessel obstruction. This stage leads to a more severe pain while walking at a relatively shorter distance known as intermittent claudication. This is followed by pain even at rest which increases when the limb is raised. The worst and rather irreversible stage is the stage of biological tissue loss and gangrene. Other associated symptoms are sores, wounds and ulcers of the affected area that are usually poor in healing or do not heal at all. Some noticeable colour changes means the affected part turns pale and colder than the the normal part and diminshed hair and nail growth can be noticed .

The risk factors include

1. Smoking, the single most important modifiable cause of peripheral vascular disease internationally. Smokers have a ten fold increase in relative risk for the disease.

2. Diabetes mellitis causes 2-4 times increase risk of the disease. This group acounts for approximately upto 70% of the non traumatic amputations performed . A known diabetic who smokes increases his risk of getting the vascular insufficiency.

3. Dyslipidemias including eleveted cholesterol levels, high bad cholesterols known as LDL, low good cholesterols, HDL, elevated triglyceride levels are also co related with PVD(peripheral vascular disease)

4. High blood pressures is associated with increased risk of PVD as well as with heart attacks and strokes.

Some of the tests the doctor may rely to diagnose are

1. Physical examination: might reveal signs such as weak or absent pulses in the affected limb, whooshing sounds known as bruits can be heard with a stethescope, evidence of poor wound healing and decreased blood pressure in the affected limb

2. Ankle Brachial Preesure Index:it is a common test to diagnose PVD. It compares the blood pressure in the ankle to the blood pressure in the arm.If the blood pressure reading in the ankle is lower than that in the arm, blockage of the arteries providing blood from the heart to distal lower limb is suspected.

3. Ultrasound: Special ultrasound imaging techniques, such as doppler ultrasound helps to look for site and extent of blockage or narrowing of arteries.

4. Angiography:modern diagnostic imaging techniques such as magnetic resonance angiography (MRA) or computed tomography angiography(CTA) allows the imaging of the arterial system following the injection of a dye in the blood vessels. Some more invasive procedures for example catheter angiography allows diagnosis as well as treatment at the same time which involves passage of a catheter from an artery in the groin of the patient to the affected narrowed part of the artery and widening that part with angioplasty procedure or injecting some medicine to improve the blood flow in that part

5. Blood tests: for diabetes and cholesterol levels

The treatment aims at

a. Relieving symptoms such as leg pain etc

b. To stop the progression of atherosclerosis throughout the body to reduce risk of heart attacks and stroke. The first step in achieving these goals is to change one’s lifestyle. Quiting smoking is the single most important thing to reduce the risk of complications. Mangement of diabetes, management of high blood cholesterol levels and high blood pressures all contribute to reduce the rate of disease progression and to avoid the complications. If medical treatment alone is insufficient surgical intervention may be required in the form of angioplasty or bypass surgery. Moreover supervised exercise programs can help to increase he distance a patient can walk pain free.

Critical limb ischemia is a serious complication that begins as open sores that dont heal, an injury or an infection of the feet or legs and they progress to tissue death and gangrene sometimes requiring amputations of the affected limb.Heart attack an stroke are other complications if the fat deposits also build in arteries supplying the heart and brain respectively.

Mesothelioma is a cancer in the lining of the lungs, heart or abdominal cavity that is caused by exposure to asbestos. Common symptoms include difficulty breathing, side or back pain, fluid buildup, nausea and vomiting. Mesothelioma cancers have a long latency, often not developing symptoms for decades after the initial exposure to asbestos. They are also difficult to diagnose, as the symptoms mimic a number of other, minor, conditions. Often, even after symptoms develop, patients won’t seek help for what they believe are mild colds or stomach ailments. For this reason, diagnosis usually doesn’t occur until the cancer is already in advanced stages, making treatment difficult.

Mesothelioma Treatment Options

At this point, there is no cure for mesothelioma. However there are several treatments available which can improve the prognosis, extending both life expectancy and quality of life. Early diagnosis has a major impact on the effect of treatments, and the prognosis of the disease.

Surgery

In the early stages, if the cancer is diagnosed quickly enough, surgery to remove the tumor can be very helpful. The most important thing for surgery to be an option is the cancer cannot have metastasized yet – spread to other parts of the body. Once multiple tumors have developed and spread, surgery is no longer an option in mesothelioma treatment.

Chemotherapy

Chemotherapy is probably the most common mesothelioma treatment. There are limited chemotherapy drugs which can be used as treatment with different mesotheliomas. In early stages, chemotherapy, especially in concert with surgery or radiation, may be able to drive the cancer into remission. In later stages, chemotherapy acts as a palliative, reducing the effects and spread of mesothelioma cancer.
There are few chemotherapy drugs that have been approved by the FDA for mesotheliomas, and different mesotheliomas respond to different drugs. At this point, the FDA has approved the combination of Alimta(Pemetrexed) and Cisplatin for pleural mesothelioma treatment. There are no drugs currently approved for peritoneal mesothelioma treatment, however numerous clinical trials are under way for chemotherapy drugs, including Gemcitabine, Navelbine, and Onconase. Clinical trials are always seeking participants, and your oncologist can tell you if one may be helpful to your treatment.

Radiation Therapy

Radiation therapy is not and effective mesothelioma treatment on its own; other therapies are needed to manage the cancer. However radiation therapy in combination with surgery or chemotherapy can help reduce and control the spread of the tumor(s).

Alternative/Complementary Therapies

Alternative and complementary therapies have seen increasing use in cancer treatment in recent years. While alternative and complementary therapies cannot address mesothelioma directly, several of them have been used to help manage the pain and symptoms of the cancer, and to treat the side effects of chemotherapy. Acupuncture, massage, and reflexology have been used to improve quality of life in this manner. Herbalism may also be beneficial, but avoid over the counter herbal supplements, as they may interact badly with other medications. As always, go to a certified or licensed professional for any alternative or complementary therapies, and speak with your oncologist before beginning any treatments.

Peritoneal Mesothelioma is a cancer that affects the lining of the abdominal cavity. This lining is called the peritoneum. Mesothelioma is most commonly found around the lungs, and many people are not familiar with peritoneal mesothelioma and how it differs from pleural (lung) mesothelioma.
The lining of the abdominal cavity surrounds the area from the diaphragm down to the hip, and helps to support all the major organs in the abdomen, including the stomach, liver, intestines, kidneys and gall bladder. This lining is filled with fluid, and acts as a lubricant so the organs can expand as they fill and empty. When peritoneal mesothelioma develops, if can affect all of these organs.

Origins of Peritoneal Mesothelioma

The only known cause of peritoneal mesothelioma is asbestos exposure. Asbestos is a natural mineral fiber that was once used heavily in the construction industry, and could be found in ship yards, steel mills, and construction sites. It was also used as an insulator for plumbing and electrical wires.
People working around asbestos without protective gear might ingest some of the fibers, and the fibers can work their way from the stomach to the lining of the abdominal cavity. Also, asbestos fibers often end up in the air and can be inhaled, which leads to the more common pleural mesothelioma. It is possible for fibers that were inhaled to reach the lining through the lungs and lymph nodes.
It takes a lot of exposure to asbestos to lead to peritoneal mesothelioma. Either a exposure to a huge amount of asbestos over a moderate amount of time (say a month or more), or exposure to a large amount of asbestos over several years, or even decades.
Peritoneal mesothelioma, like all mesotheliomas, has a long latency period. Frequently, the first symptoms won’t show until decades after the exposure to asbestos.

Symptoms of Peritoneal Mesothelioma

Peritoneal mesothelioma is difficult to diagnose, because the symptoms mimic many other minor abdominal problems, or hernias. Abdominal pain, nausea, loss of weight and vomiting are among the most common symptoms. An effusion, or buildup of liquid in the abdomen is also possible.
As the tumor grows, it may press on the organs within the abdominal cavity, causing pain, blocking bowel movements, or causing other problems.

Treating Peritoneal Mesothelioma

The long latency period, and difficulty diagnosing, means that by the time peritoneal mesothelioma is diagnosed, it is often in advanced stages. This restricts the treatment options, because once the cancer spreads to other organs, surgery is rarely helpful. However, if a diagnosis is made early enough, surgery can greatly improve the prognosis. Chemotherapy and radiation therapy are often used as palliative treatments.

Peritoneal mesothelioma is a very rare cancer. There are less than 500 new diagnosis per year in the United States. Unless someone has been exposed to asbestos, there is no reason to worry about developing peritoneal mesothelioma. Anyone who has been exposed to asbestos should let their primary care physician know, so their doctors can be alert for early signs of the cancer developing.
