Adenomyosis

Adenomyosis



Overview

Adenomyosis (ad-uh-no-my-O-sis) occurs when the tissue that normally lines the uterus (endometrial tissue) grows into the muscular wall of the uterus. The displaced tissue continues to act normally — thickening, breaking down and bleeding — during each menstrual cycle. An enlarged uterus and painful, heavy periods can result.

Doctors aren't sure what causes adenomyosis, but the disease usually resolves after menopause. For women who have severe discomfort from adenomyosis, hormonal treatments can help. Removal of the uterus (hysterectomy) cures adenomyosis

Symptoms

Sometimes, adenomyosis causes no signs or symptoms or only mild discomfort. However, adenomyosis can cause:

Heavy or prolonged menstrual bleeding

Severe cramping or sharp, knifelike pelvic pain during menstruation (dysmenorrhea)

Chronic pelvic pain

Painful intercourse (dyspareunia)

Your uterus might get bigger. Although you might not know if your uterus is bigger, you may notice tenderness or pressure in your lower abdomen.

Causes

The cause of adenomyosis isn't known. There have been many theories, including:

Invasive tissue growth. Some experts believe that endometrial cells from the lining of the uterus invade the muscle that forms the uterine walls. Uterine incisions made during an operation such as a cesarean section (C-section) might promote the direct invasion of the endometrial cells into the wall of the uterus.

Developmental origins. Other experts suspect that endometrial tissue is deposited in the uterine muscle when the uterus is first formed in the fetus.

Uterine inflammation related to childbirth. Another theory suggests a link between adenomyosis and childbirth. Inflammation of the uterine lining during the postpartum period might cause a break in the normal boundary of cells that line the uterus.

Stem cell origins. A recent theory proposes that bone marrow stem cells might invade the uterine muscle, causing adenomyosis.

Regardless of how adenomyosis develops, its growth depends on the body's circulating estrogen.

Risk factors

Risk factors for adenomyosis include:

Prior uterine surgery, such as C-section, fibroid removal, or dilatation and curettage (D&C)

Childbirth

Middle age

Most cases of adenomyosis — which depends on estrogen — are found in women in their 40s and 50s. Adenomyosis in these women could relate to longer exposure to estrogen compared with that of younger women. However, current research suggests that the condition might also be common in younger women.

Complications

If you often have prolonged, heavy bleeding during your periods, you can develop chronic anemia, which causes fatigue and other health problems.

Although not harmful, the pain and excessive bleeding associated with adenomyosis can disrupt your lifestyle. You might avoid activities you've enjoyed in the past because you're in pain or you worry that you might start bleeding.

Diagnosis

Some other uterine conditions can cause signs and symptoms similar to those of adenomyosis, making adenomyosis difficult to diagnose. These conditions include fibroid tumors (leiomyomas), uterine cells growing outside the uterus (endometriosis) and growths in the uterine lining (endometrial polyps).

Your doctor might conclude that you have adenomyosis only after ruling out other possible causes for your signs and symptoms.

Your doctor may suspect adenomyosis based on:

Signs and symptoms

A pelvic exam that reveals an enlarged, tender uterus

Ultrasound imaging of the uterus

Magnetic resonance imaging (MRI) of the uterus

In some instances, your doctor might collect a sample of uterine tissue for testing (endometrial biopsy) to make sure you don't have a more serious condition. But an endometrial biopsy won't help your doctor confirm a diagnosis of adenomyosis.

Pelvic imaging such as ultrasound and Magnetic resonance imaging (MRI) can detect signs of adenomyosis, but the only way to confirm it is to examine the uterus after hysterectomy.

Treatment

Adenomyosis often goes away after menopause, so treatment might depend on how close you are to that stage of life.

Treatment options for adenomyosis include:

Anti-inflammatory drugs. Your doctor might recommend anti-inflammatory medications, such as ibuprofen (Advil, Motrin IB, others), to control the pain. By starting an anti-inflammatory medicine one to two days before your period begins and taking it during your period, you can reduce menstrual blood flow and help relieve pain.

Hormone medications. Combined estrogen-progestin birth control pills or hormone-containing patches or vaginal rings might lessen heavy bleeding and pain associated with adenomyosis. Progestin-only contraception, such as an intrauterine device, or continuous-use birth control pills often cause amenorrhea — the absence of your menstrual periods — which might provide some relief.

Hysterectomy. If your pain is severe and no other treatments have worked, your doctor might suggest surgery to remove your uterus. Removing your ovaries isn't necessary to control adenomyosis.

Charge Syndrome

Overview CHARGE syndrome is a recognizable genetic syndrome with known pattern of features. It is an extremely complex syndrome, involving extensive medical and physical difficulties that differ from child to child. CHARGE syndrome is correlated with genetic mutation to CHD7 and the prevalence of CHARGE syndrome is 1:10,000-1:15,000 live births. Babies with CHARGE syndrome are often born with life-threatening birth defects. They spend many months in the hospital and undergo many surgeries and other treatments. Swallowing and breathing problems make life difficult even when they come home. Most have hearing two little girls sitting on a carpet, one girl has a trach and is biting her finger.loss, vision loss, and balance problems that delay their development and communication. Despite these seemingly insurmountable obstacles, children with CHARGE syndrome often far surpass their medical, physical, educational, and social expectations. One of the hidden features of CHARGE syndrome is the ...

Dehydration Due to Diarrheal Diseases

Overview Dehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions. If you don't replace lost fluids, you will get dehydrated. Anyone may become dehydrated, but the condition is especially dangerous for young children and older adults. The most common cause of dehydration in young children is severe diarrhea and vomiting. Older adults naturally have a lower volume of water in their bodies, and may have conditions or take medications that increase the risk of dehydration. This means that even minor illnesses, such as infections affecting the lungs or bladder, can result in dehydration in older adults. Dehydration also can occur in any age group if you don't drink enough water during hot weather — especially if you are exercising vigorously. You can usually reverse mild to moderate dehydration by drinking more fluids, but severe dehydration needs immediate medical treatment. ...

Ataxia with Vitamin E Deficiency

Synonyms of Ataxia with Vitamin E Deficiency AVED Familial Isolated Vitamin E Deficiency Isolated Vitamin E Deficiency General Discussion Ataxia with vitamin E deficiency (AVED) is a rare inherited neurodegenerative disorder characterized by impaired ability to coordinate voluntary movements (ataxia) and disease of the peripheral nervous system (peripheral neuropathy). AVED is a progressive disorder that can affect many different systems of the body (multisystem disorder). Specific symptoms vary from case to case. In addition to neurological symptoms, affected individuals may experience eye abnormalities, disorders affecting the heart muscles (cardiomyopathy), and abnormal curvature of the spine (scoliosis). AVED is extremely similar to a more common disorder known as Friedreich’s ataxia. AVED is inherited as an autosomal recessive trait. Vitamin E deficiency often occurs secondary to disorders that impair the absorption of vitamin E from fat including liver disorders, disorders of fat...
