How Ultrasound works
How Ultrasound works samer kareem 2,521 Views • 2 years ago

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats, whales and dolphins, as well as SONAR used by submarines. In ultrasound, the following events happen: The ultrasound machine transmits high-frequency (1 to 5 megahertz) sound pulses into your body using a probe. The sound waves travel into your body and hit a boundary between tissues (e.g. between fluid and soft tissue, soft tissue and bone). Some of the sound waves get reflected back to the probe, while some travel on further until they reach another boundary and get reflected. The reflected waves are picked up by the probe and relayed to the machine. The machine calculates the distance from the probe to the tissue or organ (boundaries) using the speed of sound in tissue (5,005 ft/s or1,540 m/s) and the time of the each echo's return (usually on the order of millionths of a second). The machine displays the distances and intensities of the echoes on the screen, forming a two dimensional image like the one shown below.

Condoms: Facts you should know
Condoms: Facts you should know Alicia Berger 4,088 Views • 2 years ago

Most of us have taken a sex education class or two. We know what condoms are supposed to be used for. Whether or not people use condoms every time they are necessary is a totally different story. You were probably taught the necessary but embarrassing lesson of how to put a condom on by the visual aids your sex education teacher provided. Of course, these tactics are a little more modern, so depending on how old you are, you may not have learned the basics of condom use until after high school. Yes, condoms are a pretty smart invention and they’re pretty safe to use. They are over 90% effective against sexually transmitted diseases (STDs), and of course, they help to reduce the risk of pregnancy by 98%. Some guys claim that they’re not comfortable to wear, which is why some companies have come up with new condoms that have a more natural fit and provide pleasure for both partners. However, with all the things we know about condoms, there’s still so much we don’t know. Here are 10 facts about condoms that are just as interesting as the condoms themselves.

Chordoid meningioma
Chordoid meningioma samer kareem 14,365 Views • 2 years ago

Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The patient presented with two concurrent intracranial meningiomas, with one a meningotheliomatous subtype and the other a chordoid meningioma. Given the wide array of histological differential diagnoses in chordoid meningioma, immunohistochemistry has a significant role to play in differentiating them. Recurrence in chordoid meningioma can be generally predicted based on the extent of resection, the percentage of chordoid element, and proliferation indices.
