Mammography that does not tighten and without radiation is in tests

Mammography that does not tighten and without radiation is in tests

Mammography is a radiological examination for evaluation of the breasts, made with an X-ray machine called a mammograph. It can identify benign lesions and cancers, which usually present as nodules, or calcifications. This test is used for the early detection of breast cancer before it is even clinically identified by palpation.

However, many women do not like to perform it because they feel pain and discomfort in the process. between two metal plates. Thinking about it, doctors at Eindhoven University of Technology in the Netherlands are creating a new test that promises to remain highly effective in detecting tumors without causing any pain.

Currently, the scan makes x-rays of the breasts, to identify possible tumors. However, exposure to x-rays is also something that worries women, as it may represent a risk factor for breast cancer in some cases.

Called Specific Dynamic Contrast Ultrasound, the new examination is not performed either with radiation and also has 3D images, facilitating the visualization of malignant tumors.

In the test, air microbubbles are injected that run through the veins of the breasts. From there, it is observed if the blisters find any obstruction in the way, an indication of tumor. Doctors also noticed that the bubbles vibrate twice: one on the same frequency of the sound wave apparatus and another on a double frequency.

This secondary frequency is delayed by air bubbles and this difference is noticeable when emitting sound waves from one side and capture it from the other. Further clinical trials will still be needed to understand whether this vibration can bring a detailed map into the breasts and make a 3D report possible. If everything is confirmed, the device is expected to replace mammography in 10 years.

Ministry of Health clarifies relationship of larvicidal pyriproxifen with microcephaly

According to the Ministry of Health, there is no epidemiological study to prove the association of the use of larvicidal pyriproxifen and microcephaly. The Ministry of Health only uses larvicides recommended by the World Health Organization (WHO). Pyriproxifen is among the products approved by this committee and is also certified by Anvisa (National Agency for Sanitary Surveillance), which assesses the Contrary to the relationship between the Zika virus and microcephaly, which has already been confirmed in tests that indicated the presence of the virus in samples of blood, tissues and amniotic fluid, the association between the use of pyriproxyfen and microcephaly has no scientific basis.

BIOFILME plaque, which is the most current term, is defined by the layer of microorganisms that is firmly adhered to the surfaces of teeth. BIOFILME is made up of many colonies of bacteria, mucosal cells, blood cells, enzymes, minerals, proteins, pigments and food debris. It can be considered an ecosystem and undergoes continuous changes, varying in composition in the different places of the mouth, and person to person.
