Bone marrow biopsy and bone marrow aspiration are procedures to collect and examine bone marrow — the spongy tissue inside some of your larger bones. Bone marrow biopsy and aspiration can show whether your bone marrow is healthy and making normal amounts of blood cells. Doctors use these procedures to diagnose and monitor blood and marrow diseases, including some cancers, as well as fevers of unknown origin. Bone marrow has a fluid portion and a more solid portion. In bone marrow biopsy, your doctor uses a needle to withdraw a sample of the solid portion. In bone marrow aspiration, a needle is used to withdraw a sample of the fluid portion.
Labia minoraplasty is an elective procedure that can reduce the size and reshape the inner vaginal lips. Large or asymmetrical labia minora can leave you feeling self-conscience in tight clothing or during intimacy. Long labia may result in rubbing, irritation or discomfort during intercourse and exercise. Certain skin conditions can cause increased sensitivity or tearing of the labia minora. In some cases, the labia minora may be fused with tissue in the labia majora and require medical correction.
Breast cancer is a malignant tumor that develops from the cells of
the breast. It is the most common type of cancer among women in
the United States. It is most often curable when found early. The
normal breast consists of three main components: the lobules
(milk-producing glands), the ducts (thin tubes that connect the
lobules to the nipple) and the stroma (fatty tissue and ligaments
surrounding the ducts and lobules, blood vessels, and lymphatic
vessels). About 80% of breast cancers start in the ducts.
This medical animation shows laparoscopically assisted gallbladder removal surgery, or cholecystectomy. The animation begins by showing the normal anatomy of the liver and gallbladder. Over time, gallstones form within the gallbladder, blocking the cystic duct, and causing the gallbladder to become enlarged and inflamed. The procedure, sometimes called a "lap-chole", begins with the insertion of four trocar devices, which allow the physician to see inside the abdomen without making a large incision. Air is added to the abdominal cavity to make it easier to see the gall bladder. Next, we see a view through the laparascope, showing two surgical instruments grasping the gallbladder while a third severs the cystic duct. After the gallbladder is removed, the camera pans around to show that the cystic artery and vein, have already been clipped to prevent bleeding.

The typical radiograph is of a well-defined, rounded, retrocardiac opacity with an air-fluid level. In this image, the radiolucent gas is highlighted in blue, while the gastric contents are highlighted in the green. In many cases of hiatal hernia, there will not be an air bubble below the left hemidiaphragm. This is a relatively expected finding considering that the stomach is no longer in its usual position. The anatomical position of the herniated organ can be further elucidated on the lateral radiograph. Here we can see that the stomach is in the middle mediastinum posterior to the heart and above the diaphragm. Hiatal hernias can look similar to a retrocardiac lung abscess or another cavitary lesion, but it will change in size and shape between radiographs. Large hernias can shift the mediastinum to the right and result in a widening of the carinal angle. They can even give the appearance of cardiomegaly. In this radiograph, the cardiac silhouette is distinctly visible within the confines of the hiatal hernia. To review, a hiatal hernia on an AP chest radiograph typically appears as a round retrocardiac opacity with an air-fluid level.

Ettore Vulcano, MD, Foot and Ankle Orthopedic Surgeon at Mount Sinai West, discusses a new minimally invasive bunion surgery that has patients walking immediately after surgery, and getting back to an active lifestyle much quicker than with the traditional surgery.
Since the first replant more than 50 years ago, thousands of severed body parts have been reattached, preserving the quality of life for thousands of patients through improved function and appearance that the void remaining after amputation cannot provide. Ronald Malt performed the first replantation on May 23, 1962 at Massachusetts General Hospital on a 12-year-old boy who had his right arm amputated in a train accident. [1, 2] This amputation occurred at the level of the humeral neck.

Purpose of the video is to help Esthetician’s review chapters in their text book to better prepare for State Bord testing, by simply reading and going over some of the material, it’s not intended to replace any teaching from any Beauty College. Every instructor does things different, Keep in mind I am in the state of Texas, also keep in mind that when in school students are to follow guidelines and might be required to do things a bit different, I teach my students the text book because that is where the state board questions come from and the goal is for them to pass their board exams. I also teach them and go over real working situations they might come across in the salon or spa.

This sqadia.com short video clip is a brief explanation of Epithelium.
Epithelium is one of the four basic tissues of the body and is derived from all three germ layers.
It is composed of very closely packed, contiguous cells, with very little or no extracellular material in the extracellular spaces.

When there are two or more layers of cells epithelia is referred to as stratified, hence can be stratified squamous, stratified cuboidal and stratified columnar.
