The cause of keratitis is vary. Bacteria, viruses, and fungi is one of the most factors that can cause keratitis. Other causes are dryness of the eyes caused by the use of contact lenses, foreign objects into the eye, or even more irritating. In addition, vitamin A deficiency and the use of contact lenses that are less well also be one cause of keratitis.

Keratitis cases are often found in those who are too often using contact lenses. Contact lens users are often lack  in contact lens hygiene. For example, a contact lens that is rarely cleaned up after use or the use of contact lenses that have expired.

Keratitis often occurs because patients do not store or disinfect contact lenses properly, which causes infection in the eye. Apart from the user subjects factor, there is also an activity that can be risk factors for this disease are wearing contact lenses while swimming or bathing in the shower (shower) without removing contact lenses.

Some of the symptoms of keratitis caused by them, out of excessive tears and pain very much on the eyes. In addition there is also decreased visual acuity. In some cases also found inflammation in the eyelid that causes the eyes become red and swollen and very sensitive to excessive light.

This disease occurs because the cornea is injured and feared would happen to blindness if not immediately get medical treatment. In case of further keratitis can look like a ring that covers the iris.

Diagnosis and Treatment

Diagnosis is done by a way called anamnesis and which would find out the early history of the patient. The diagnosis of keratitis is rarely done properly at an early stage. This disease usually can be diagnosed after all efforts that have been done for treatment was failure.

Less Keratitis patients which receive right medical diagnosis, because this disease is often suspected as herpes simplex keratitis. Other diseases that also have similarities with keratitis which is caused by fungi and keratitis due to mycobacterium. The diagnosis can also be proved by investigation. Investigations that can be done by performing a corneal biopsy culture by finding its amoeba form.

Eyedroppers or antibiotic eye ointment, antifungal, and antiviral usually given to cure keratitis, but these drugs should only be given with a doctor’s prescription. Wrong or bad treatment could cause deterioration of the symptoms. Topical corticosteroid medicines can cause corneal deterioration in patients with keratitis due to herpes simplex virus.

It takes more than one kind of treatment. Surgical laser therapy are sometimes made to the already heavy case, because the patient needed a corneal transplant.

Kidney is an important part of the body and that is the reason there are two and not one. Even if one stops to function the person could still live normal with one kidney. However, problem occurs when both these face a kidney failure. The kidney controls and manages fluids in the body and at the same time helps disposing off the waste fluids from the body. There are many causes of kidney failure which can be grouped as prerenal causes; renal causes; Post renal causes; chronic renal failure.

When the supply of blood to the kidneys is reduced it is said to be the prerenal cause for the kidney failure. The prerenal causes could be Hypovolemia means low volume of blood caused due to loss of blood; dehydration; less than required intake of fluids; certain medication can cause fluid loss.

When the kidney is damaged directly to result into a kidney failure it is called the renal causes of kidney failure. Sepsis, medications, rhabdomyolysis, multiple myeloma and acute glomerulonephritis would be covered under the renal causes. When the outflow of urine is obstructed due to certain reasons it is called the post renal causes of kidney failure. Bladder obstruction, prostate cancer or Prostatic hypertrophy; tumors and kidney stones could be the reasons obstructing the urine flow.

The chronic renal failure would include diabetes; high blood pressure; chronic glomerulonephritis. The Polycystic Kidney Disease; Reflux nephropathy; Kidney stones and Prostate disease could be the less common causes.

The symptoms that could be a sign of kidney failure would be –

1-In the beginning there would not be any noticeable symptoms that could be seen or realized. Later, metabolic acidosis
due to the inability of the kidney to manufacture bicarbonate would affect the oxygen and enzyme metabolism this would result in kidney failure.

2-Rising potassium levels would be there.

3-Urea levels would be rising in the blood.

4-Generalized weakness due to the reduced blood cell count.

5-The affects of waste in the body like – lethargy, loss of appetite and fatigue would start to get to surface.

6-Breathing would become rapid.

The treatment of kidney failure would depend upon the stage at which the person is. The diagnosis of the kidney failure and the severity of the same are done by taking a blood test. The level of waste in the blood would help to see how bad the kidney has started to function. Further, the urine tests could be taken. The presence of proteins in the urine would tell that the kidney has stopped to function.

Ultrasound of the abdomen and biopsy are the other tests that would be suggested by the doctor to dig deep. If the is at the stage that the kidney could be saved by medications or a minor surgery for that matter – these are undertaken to prevent a total kidney failure. And in c se noting could be doneFree Articles, and then kidney transplantation in considered if both the kidneys fail to function the way they should.

A routine breast examination is advised for all women to identify any suspicious lumps so that breast cancer detection is made as early as possible. Mammography is the most common first line screening tool for breast cancer. But in some cases, mammography may miss some abnormalities, especially if the woman’s breast tissue is dense. Sometimes dense breast tissue and cancers may appear similar in mammography.

So, a lump that may be felt manually may appear as normal breast tissue when screened through mammography which may then lead to a biopsy to confirm cancer. But now, even the cancerous tissue that mammography misses can be identified by a new diagnostic technique called breast specific gamma imaging. Read the rest of this entry »
