doctor%20office.jpgExperts estimate that each year, as many as 12-million Americans visit an outpatient clinic and are wrongly diagnosed. The high rates of diagnostic errors in outpatient clinics remains unaddressed while health care experts and industry officials continue to focus on hospital-based diagnostic and other medical errors.

According to a new analysis of data from several published studies, primary clinics, doctors’ offices and other outpatient settings account for a large percentage of all diagnostic errors recorded every year. Statistics suggest that as many as 1 in 20 people who visit an outpatient clinic are misdiagnosed.

Misdiagnoses are serious medical errors because, at the very least they increase the risk of delayed treatment. In the worst scenario, they result in fatalities. A misdiagnosis occurs when a doctor fails to accurately identify a medical condition. When the patient’s condition is wrongly diagnosed, the wrong treatment may begin and the original condition may be left to worsen.

surgical%20blade.jpgNew electrosurgery technology that makes use of a knife that can sniff out cancer cells as it cuts through tissue, is making headlines.

The knife, developed by researchers at the Imperial College of London, is based on an electrosurgery technique in which the knife uses an electric current to heat up tissue as it cuts. This rapid cutting combined with high heat results in minimal blood loss and vaporizes the tissue instantly. When the tissue is incinerated, it creates a smoke which is sucked into extraction systems. The smoke contains important information that can provide critical data about the characteristics of the tissue that emits the smoke.

The Intelligent Knife or iKnife, can analyze samples of the smoke, and determine the presence of cancer cells in the tissue. The researchers who have developed the surgical knife recently explained the technique in Science Translational Medicine, and say that the surgery has been combined with a technique known as rapid evaporative ionisation mass spectrometry.

cancer%20slide.jpgUnnecessary screening for ovarian cancer using a test that often produces false-positive results can place women at risk of injuries, including unnecessary removal of ovaries. Therefore, the US Preventive Services Task Force continues to recommend that ovarian cancer screenings be restricted to those cases in which the person shows symptoms of ovarian cancer, or is already genetically predisposed to the cancer.

Ovarian cancer is the fifth-leading cause of cancer-related death among women in the United States, and is also believed the deadliest of all gynecological cancers. According to the Centers for Disease Control and Prevention, most women diagnosed with ovarian cancer are above the age of 40, and the maximum number of cases are found in those aged about 60 years.

The current methods for the diagnosis of ovarian cancer are transvaginal ultrasonography and a test called the CA-125 test. This test is administered to determine the number of a specific type of blood protein in the person’s body that can signify the presence of ovarian cancer.
