Absence of a woman's monthly menstrual period is called amenorrhea. Secondary amenorrhea is when a woman who has been having normal menstrual cycles stops getting her periods for 6 months or longer. Causes Secondary amenorrhea can occur due to natural changes in the body. For example, the most common cause of secondary amenorrhea is pregnancy. Breastfeeding and menopause are also common, but natural, causes. Women who take birth control pills or who receive hormone shots such as Depo-Provera may not have any monthly bleeding. When they stop taking these hormones, their periods may not return for more than 6 months. You are more likely to have absent periods if you: Are obese Exercise too much and for long periods of time Have very low body fat (less than 15 to 17%) Have severe anxiety or emotional distress Lose a lot of weight suddenly (for example, from strict or extreme diets or after gastric bypass surgery) Other causes include: Brain (pituitary) tumors Drugs for cancer treatment Drugs to treat schizophrenia or psychosis Overactive thyroid gland Polycystic ovarian syndrome Reduced function of the ovaries

For benign colorectal diseases, totally laparoscopic left-sided colectomy was already reported on some papers. Nowadays, there is increasingly demanded minimally invasive surgerys on malignant bowel diseases including colorectal cancers and so we developed the new techniques in that specimen is del...ivered through the open rectal stump, especially, using Sani Sleeve(TM). In this operation video, you can see that an anvil was fixed to proximal colonic stump with intracorporeal purse-string suture using Endo-stitch(TM). (SETA : Specimen Extraction Through Anus)

This is the incredible moment a new-born baby arrived still inside its amniotic sac, completely intact. The tiny infant can be seen moving and stretching still inside the sac, as medics prepare to snip the new born free. The amniotic sac is a thin but durable membrane filled with fluid which helps keep a baby warm and safe from bumps during pregnancy. When it breaks, this is typically referred to as a woman's 'waters breaking' shortly before she gives birth. But in rare cases, less than 1-in-80,000 births, the baby is delivered with the membranes still intact and this is known as a 'caul birth'. Some babies are born with part of the membrane still attached to them, but to be born completely encased in the intact membrane is incredibly rare. Many people still believe the phenomenon to be a good omen for the child's infancy and it is has even been suggested, but not proven, that caul babies will always have a natural affinity for water. The video was taken in Spain on Saturday and captures the rare moment the baby was born with the membrane covering its entire body, just minutes after its twin was delivered normally.

A central venous catheter (CVC), also known as a central line, central venous line, or central venous access catheter, is a catheter placed into a large vein. Catheters can be placed in veins in the neck (internal jugular vein), chest (subclavian vein or axillary vein), groin (femoral vein), or through veins in the arms (also known as a PICC line, or peripherally inserted central catheters). It is used to administer medication or fluids that are unable to be taken by mouth or would harm a smaller peripheral vein, obtain blood tests (specifically the "central venous oxygen saturation"), and measure central venous pressure.

A tissue is a group of cells that has a similar structure and acts together to perform one or more specific functions. In this tutorial, we will introduce you to the 4 main types of tissues in the human body: epithelial tissue, connective tissue, muscle tissue and nervous tissue. Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules, whereas connective tissue underlies and supports other tissue types.

Muscle tissue contracts to initiate movement in the body and nervous tissue transmits and integrates information through the central and peripheral nervous systems.

In this video tutorial we will take a closer look at the histology of the main cells and tissues under the microscope.

Marfan syndrome is a genetic disorder that affects the body's connective tissue. Connective tissue holds all the body's cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly. Connective tissue is made up of proteins.

Typically, breast reconstruction takes place during or soon after mastectomy, and in some cases, lumpectomy. Breast reconstruction also can be done many months or even years after mastectomy or lumpectomy. During reconstruction, a plastic surgeon creates a breast shape using an artificial implant (implant reconstruction), a flap of tissue from another place on your body (autologous reconstruction), or both.

The biceps muscle is located in the front of your upper arm. It is attached to the bones of the shoulder and elbow by tendons — strong cords of fibrous tissue that attach muscles to bones. Tears of the biceps tendon at the elbow are uncommon. They are most often caused by a sudden injury and tend to result in greater arm weakness than injuries to the biceps tendon at the shoulder. Once torn, the biceps tendon at the elbow will not grow back to the bone and heal. Other arm muscles make it possible to bend the elbow fairly well without the biceps tendon. However, they cannot fulfill all the functions of the elbow, especially the motion of rotating the forearm from palm down to palm up. This motion is called supination. To return arm strength to near normal levels, surgery to repair the torn tendon is usually recommended. However, nonsurgical treatment is a reasonable option for patients who may not require full arm function.

Duodenal atresia, also known as duodenojejunal atresia, is the congenital absence or complete closure of a portion of the lumen of the duodenum. It causes increased levels of amniotic fluid during pregnancy (polyhydramnios) and intestinal obstruction in newborn babies.

When you get a kidney transplant, a healthy kidney is placed inside your body to do the work your own kidneys can no longer do. On the plus side, there are fewer limits on what you can eat and drink, but you should follow a heart-healthy diet. Your health and energy should improve. In fact, a successful kidney transplant may allow you to live the kind of life you were living before you got kidney disease. Studies show that people with kidney transplants live longer than those who remain on dialysis. On the minus side, there are the risks of surgery. You will also need to take anti-rejection medicines for as long as your new kidney is working, which can have side effects. You will have a higher risk for infections and certain types of cancer.
