Bone Marrow Biopsy

What Is a Bone Marrow Biopsy?


A bone marrow biopsy is really a process that takes a tiny sample from the marrow within your bones for examining inside a laboratory. This kind of test can be used to determine if you have an infection, disease, and , or other problems in your bone marrow.

Marrow has the two reliable and liquid elements. If the solid part of the bone is sampled, this is often named a biopsy. Aspiration is the technique utilized to acquire the liquid a part of the marrow.

Bone marrow could be the spongy tissue found out inside your bones. From the much larger bones- like your spine, breastbone, hips, ribs, legs, or skull-bone marrow involves cells in which make white blood cells, Red blood cells, too as platelets. Your very own white blood cells aids in preventing infection, your Red blood cells carry oxygen also  nutrition, whilst  your platelets stimulate the blood to clot

Troubles with bone marrow can develop lasting, significant well being worries. A bone marrow biopsy is among a lot of tests which can be done to examine the cells of the bone marrow for difficulties or diseases.

Why Is a Bone Marrow Biopsy Done?



If blood screening exhibit lower amounts of platelets or white or red blood cells, your physician may
possibly order a bone marrow biopsy.

Problems as well as illnesses that could affect your bone marrowinclude:

1- Anemia,all types

2- bone marrow diseases, such as myelofibrosis or myelodysplastic syndrome

3- blood cell illnesses, like as leukopenia or polycythemia

4- cancers of the bone marrow or blood, like as leukemias or lymphomas

5- hemochromatosis, a genetic disorder in which iron builds in the blood

infection, such as sepsis


NB.
A bone marrow biopsy can be a crucial take a look at should you be undergoing cancer treatment, as it might help identify if the most cancers has unfold in your bones

Risks of a Bone Marrow Biopsy
On the other hand in some uncommon situations, the following complications are probable:

A- allergic reaction to anesthesia

B- excessive bleeding

C- infection

D- long-lasting discomfort at the spot exactly where the biopsy was taken
These dangers are rare and most generally take place among individuals who have other situations that weaken their immune systems or decrease their platelet counts

How to Prepare for a Bone Marrow Biopsy?





Your medical doctor will carry out various examinations prior to the biopsy. Through these tests, be sure to tell your physician about any medications you take-including over-the-counter medicines or nutritional supplements-and any known allergies you have got.

Your doctor may possibly ask you to stop taking specific medicines prior to the process. By no means stop taking a medication unless your medical professional instructs you to complete so.

Tell your medical doctor should you be nervous. He or she may well give you a mild sedative that will help you via your process.

Stick to all of your doctor’s instructions before the process. Usually do not overlook to show up on time for your biopsy. You might also choose to arrange to get a ride dwelling.

How a Bone Marrow Biopsy Is Performed?


you will be asked to alter into a hospital gown, Ahead of the test. Then you will stay in your part or rest in your tummy in a area exactly where the process is going to take place.

A doctor or registered nurse will provide you with a nearby sedation to numb the location exactly where the biopsy is going to be used. Usually this may be at the major ridge of your back end hipbone. Occasionally it might be studied from your upper body bone fragments.

You might really feel a brief sting as the anesthesia is injected.

Your medical professional is likely to make a modest cut so a hollow needle can easily get previous the facial skin. The needle then will go in to the bone tissue. It records a cylinder-formed test recognized like a primary sample.
According to the National Institutes of Overall health, some individuals feel a dull discomfort or discomfort because the biopsy is taken, since the inside of the bones cannot be numbed. the Federal Organizations of Wellness, a number of people feel a uninteresting pain or soreness because the biopsy is taken, considering the fact that the inside of the bones can not be numbed, . Even so, not every person will experience this. (NIH, 2010)

Right away following the process, the cut might be bandaged, and you will be used into one more area to relax just before going home.

After a Bone Marrow Biopsy

You could feel some slight discomfort for about per week just after the procedure. That is easily managed with over-the-counter pain relievers. You are going to also need to care for the incision wound, which includes maintaining it dry for 24 hours following the biopsy.

When you happen to be caring for the wound, your bone marrow sample is going to be sent to a laboratory for testing. When the outcomes are back, your doctor may possibly contact you or have you come to their workplace to get a follow-up appointment to talk about the findings.

Abnormal results may be as a result of cancer, anemia, or an additional condition. Your physician may require to order far more tests to confirm a diagnosis or to determine how far the condition has gone. She or he will discuss your treatment options with you and enable you to strategy your subsequent measures during your follow-up appointment.

The Five Steps of a Breast Self-Exam

The Five Steps of a Breast Self-Exam

Supported by Video:


Step 1: Start by looking at your breasts in the mirror with your shoulders straight and your arms on your hips as shown in the photo
Step-1
Here's what you should look for:
Notice:
  • Breasts that are their usual size, shape, and color
  • Breasts that are evenly shaped without visible distortion or swelling

If you see any of the following changes, bring them to your doctor's attention:
  • Dimpling, puckering, or bulging of the skin
  • A nipple that has changed position or an inverted nipple (pushed inward instead of sticking out)
  • Redness, soreness, rash, or swelling

Breast Self-Exam - Step 1
Breast Self-Exam — Step 1
Step 2: Now, raise your arms and look for the same changes as shown in the photo.
Step 3: While you're at the mirror, look for any signs of fluid coming out of one or both nipples (this could be a watery, milky, or yellow fluid or blood).
Breast Self-Exam - Steps 2 and 3
Breast Self-Exam — Steps 2 and 3
Step 4: Next, feel your breasts while lying down, using your right hand to feel your left breast and then your left hand to feel your right breast. Use a firm, smooth touch with the first few finger pads of your hand, keeping the fingers flat and together. Use a circular motion, about the size of a quarter.
Cover the entire breast from top to bottom, side to side — from your collarbone to the top of your abdomen, and from your armpit to your cleavage.
Follow a pattern to be sure that you cover the whole breast. You can begin at the nipple, moving in larger and larger circles until you reach the outer edge of the breast. You can also move your fingers up and down vertically, in rows, as if you were mowing a lawn. This up-and-down approach seems to WORK best for most women. Be sure to feel all the tissue from the front to the back of your breasts: for the skin and tissue just beneath, use light pressure; use medium pressure for tissue in the middle of your breasts; use firm pressure for the deep tissue in the back. When you've reached the deep tissue, you should be able to feel down to your ribcage.
Breast Self-Exam - Step 4
Breast Self-Exam — Step 4
Step 5: Finally, feel your breasts while you are standing or sitting. Many women find that the easiest way to feel their breasts is when their skin is wet and slippery, so they like to do this step in the shower. Cover your entire breast, using the same hand movements described in step 4.

Lymph Node Locations video

-->



A lymph node is a small ball or an oval-shaped organ of the immune system, distributed widely throughout the body including the armpit and stomach/gut and linked by lymphatic vessels. Lymph nodes are garrisons of B, T, and other immune cells. Lymph nodes are found all through the body, and act as filters or traps for foreign particles. They are important in the proper functioning of the immune system. They are packed tightly with the white blood cells called lymphocytes and macrophages.

Lymph nodes also have clinical significance. They become inflamed or enlarged in various conditions, which may range from trivial, such as a throat infection, to life-threatening such as cancers. In the latter, the condition of lymph nodes is so significant that it is used for cancer staging, which decides the treatment to be employed, and for determining the prognosis.

Lymph nodes can also be diagnosed by biopsy whenever they are inflamed. Certain diseases affect lymph nodes with characteristic consistency and location.

Anatomy of the Arm and Forearm




http://upload.wikimedia.org/wikipedia/commons/thumb/f/f8/Gray415.png/50px-Gray415.png
The forearm is the structure and distal region of the upper limb, between the elbow and the wrist. The term forearm is used in anatomy to distinguish it from the arm, a word which is most often used to describe the entire appendage of the upper limb but in anatomy, technically means only the region of the upper arm whereas the lower "arm" is called the forearm.

Anatomy of parotid gland



http://upload.wikimedia.org/wikipedia/commons/thumb/5/51/Illu_quiz_hn_02.jpg/250px-Illu_quiz_hn_02.jpg
The paired parotid glands are the largest of the salivary glands. They are found wrapped around the mandibular ramus, and secrete saliva through ducts into the oral cavity, to facilitate mastication and swallowing and to begin the digestion of starches.

Location
The parotid glands are found overlying the mandibular ramus and anterior and inferior to the external ear. Each gland extends irregularly from the zygomatic arch to the angle of the mandible. Above the parotid gland lies the external auditory meatus and temporomandibular joint. Below, the parotid overlaps the posterior belly of the digastric muscle. The parotid gland resembles a three sided pyramid. the gland has four surfaces: (1) superior (2) superficial (3) anteromedial & (4) posteromedial.
The surfaces are separated by three borders: (1) anterior (2) posterior & (3) medial
The external carotid artery, which gives off its two terminal branches, the maxillary artery and the superficial temporal artery, inside the gland

Heart Anatomy video



Coronary Arteries

Because the heart is composed primarily of cardiac muscle tissue that continuously contracts and relaxes, it must have a constant supply of oxygen and nutrients. The coronary arteries are the network of blood vessels that carry oxygen- and nutrient-rich blood to the cardiac muscle tissue.
http://photos3.fotosearch.com/bthumb/ISI/ISI119/UNIOB015.JPG
The blood leaving the left ventricle exits through the aorta, the body’s main artery. Two coronary arteries, referred to as the "left" and "right" coronary arteries, emerge from the beginning of the aorta, near the top of the heart.
The initial segment of the left coronary artery is called the left main coronary. This blood vessel is approximately the width of a soda straw and is less than an inch long. It branches into two slightly smaller arteries: the left anterior descending coronary artery and the left circumflex coronary artery. The left anterior descending coronary artery is embedded in the surface of the front side of the heart. The left circumflex coronary artery circles around the left side of the heart and is embedded in the surface of the back of the heart.
Just like branches on a tree, the coronary arteries branch into progressively smaller vessels. The larger vessels travel along the surface of the heart; however, the smaller branches penetrate the heart muscle. The smallest branches, called capillaries, are so narrow that the red blood cells must travel in single file. In the capillaries, the red blood cells provide oxygen and nutrients to the cardiac muscle tissue and bond with carbon dioxide and other metabolic waste products, taking them away from the heart for disposal through the lungs, kidneys and liver.
When cholesterol plaque accumulates to the point of blocking the flow of blood through a coronary artery, the cardiac muscle tissue fed by the coronary artery beyond the point of the blockage is deprived of oxygen and nutrients. This area of cardiac muscle tissue ceases to function properly. The condition when a coronary artery becomes blocked causing damage to the cardiac muscle tissue it serves is called a myocardial infarction or heart attack.
 

Superior Vena Cava

The superior vena cava is one of the two main veins bringing de-oxygenated blood from the body to the heart. Veins from the head and upper body feed into the superior vena cava, which empties into the right atrium of the heart.

Inferior Vena Cava

The inferior vena cava is one of the two main veins bringing de-oxygenated blood from the body to the heart. Veins from the legs and lower torso feed into the inferior vena cava, which empties into the right atrium of the heart.

Aorta

The aorta is the largest single blood vessel in the body. It is approximately the diameter of your thumb. This vessel carries oxygen-rich blood from the left ventricle to the various parts of the body.


Pulmonary Artery

The pulmonary artery is the vessel transporting de-oxygenated blood from the right ventricle to the lungs. A common misconception is that all arteries carry oxygen-rich blood. It is more appropriate to classify arteries as vessels carrying blood away from the heart.

Pulmonary Vein

The pulmonary vein is the vessel transporting oxygen-rich blood from the lungs to the left atrium. A common misconception is that all veins carry de-oxygenated blood. It is more appropriate to classify veins as vessels carrying blood to the heart.

Right Atrium

The right atrium receives de-oxygenated blood from the body through the superior vena cava (head and upper body) and inferior vena cava (legs and lower torso). The sinoatrial node sends an impulse that causes the cardiac muscle tissue of the atrium to contract in a coordinated, wave-like manner. The tricuspid valve, which separates the right atrium from the right ventricle, opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle.

Right Ventricle

The right ventricle receives de-oxygenated blood as the right atrium contracts. The pulmonary valve leading into the pulmonary artery is closed, allowing the ventricle to fill with blood. Once the ventricles are full, they contract. As the right ventricle contracts, the tricuspid valve closes and the pulmonary valve opens. The closure of the tricuspid valve prevents blood from backing into the right atrium and the opening of the pulmonary valve allows the blood to flow into the pulmonary artery toward the lungs.

Left Atrium

The left atrium receives oxygenated blood from the lungs through the pulmonary vein. As the contraction triggered by the sinoatrial node progresses through the atria, the blood passes through the mitral valve into the left ventricle.

Left Ventricle

The left ventricle receives oxygenated blood as the left atrium contracts. The blood passes through the mitral valve into the left ventricle. The aortic valve leading into the aorta is closed, allowing the ventricle to fill with blood. Once the ventricles are full, they contract. As the left ventricle contracts, the mitral valve closes and the aortic valve opens. The closure of the mitral valve prevents blood from backing into the left atrium and the opening of the aortic valve allows the blood to flow into the aorta and flow throughout the body.


Papillary Muscles

The papillary muscles attach to the lower portion of the interior wall of the ventricles. They connect to the chordae tendineae, which attach to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle. The contraction of the papillary muscles opens these valves. When the papillary muscles relax, the valves close.

Chordae Tendineae

The chordae tendineae are tendons linking the papillary muscles to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle. As the papillary muscles contract and relax, the chordae tendineae transmit the resulting increase and decrease in tension to the respective valves, causing them to open and close. The chordae tendineae are string-like in appearance and are sometimes referred to as "heart strings."

Tricuspid Valve

The tricuspid valve separates the right atrium from the right ventricle. It opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle. It closes as the right ventricle contracts, preventing blood from returning to the right atrium; thereby, forcing it to exit through the pulmonary valve into the pulmonary artery.


Mitral Value

The mitral valve separates the left atrium from the left ventricle. It opens to allow the oxygenated blood collected in the left atrium to flow into the left ventricle. It closes as the left ventricle contracts, preventing blood from returning to the left atrium; thereby, forcing it to exit through the aortic valve into the aorta.

Pulmonary Valve

The pulmonary valve separates the right ventricle from the pulmonary artery. As the ventricles contract, it opens to allow the de-oxygenated blood collected in the right ventricle to flow to the lungs. It closes as the ventricles relax, preventing blood from returning to the heart.

Aortic Valve

The aortic valve separates the left ventricle from the aorta. As the ventricles contract, it opens to allow the oxygenated blood collected in the left ventricle to flow throughout the body. It closes as the ventricles relax, preventing blood from returning to the heart.

Anatomy and Physiology of The Head and Neck video




In summary it should be pointed out that although the skeletal frame-work from which muscles operate determines to a large extent the course and direction of these organs, it is not safe to assume that it can be dismissed from our thinking. There has been a strong tendency to restrict orthodontic considerations to the morphology of the bony face and to view such morphology as static. It can never be forgotten that the close relationships between bones and muscles have been developed by adaptation and that the chief characteristic of that relationship is an equilibrium that serves to conserve energy.
http://photos1.fotosearch.com/bthumb/FSA/FSA810/x17386711.jpg
The teeth and alveolar processes should be looked upon as passive though responsive victims of a continuous interplay of muscular forces, their positions dictated by the resultants of these forces. No wishful thinking about straight profiles or upright incisors, nor the most clever appliance manipulation, will serve to hold teeth in positions that are contrary to the dictates of their muscular environment. It is to be hoped that the future will find us more aware of the significance of these matters.

Anatomy of The Liver video






The morphologic anatomy of the liver is described as 2 main and 2 accessory lobes.
http://photos3.fotosearch.com/bthumb/LIF/LIF151/ca206003.jpg
The more recent functional anatomy of the liver is based on the distribution of the portal pedicles and the location of the hepatic veins. The liver is divided into 4 sectors, some of them composed of 2 segments. In all, there are 8 segments. According to the anatomy, typical hepatectomies (or réglées) are those which are performed along anatomical scissurae. The 2 main technical conceptions of typical hepatectomies are those with preliminary vascular control (Lortat-Jacob's technique) and hepatectomies with primary parenchymatous transection (Ton That Tung's technique). A good knowledge of the anatomy of the liver is a prerequisite for anatomical surgery of this organ.
