During your menstrual period, your uterus contracts to help expel its lining. Hormonelike substances (prostaglandins) involved in pain and inflammation trigger the uterine muscle contractions. Higher levels of prostaglandins are associated with more-severe menstrual cramps.
Acromegaly is usually caused by a noncancerous tumor. Middle-aged adults are most commonly affected. Symptoms include enlargement of the face, hands, and feet. Prompt treatment is needed to avoid serious illness. Drugs can reduce the effects of growth hormone. If needed, surgery and radiation may be used to remove tumor cells.
Tension pneumothorax describes the progressive accumulation of air in the pleural cavity (normally a potential space) through a defect in the visceral pleura. This leads to positive pressure being maintained and increasing throughout the respiratory cycle causing vessels within the mediastinum to be compressed with catastrophic consequences if left untreated. Clinical signs include hypoxia, hypotension, tachycardia, reduced breath sounds and hyper resonance ipsilaterally, with tracheal deviation (away from the affected side) and distended neck veins being late clinical signs.
Bone fractures are generally caused by injury, such as a fall, car accident, or sports injury, however, bone fractures can also be caused by osteoporosis. If you have a bone fracture, you must get immediate medical attention and keep the fracture immobilized until you can get help. After the fracture has been immobilized, you can then begin natural remedies to help heal broken bones fast.
Testing for the four features of Gerstmann Syndrome in this patient with two separate left sided strokes (left frontoparietal ischaemic stroke followed by left posterior parietal haemorrhagic stroke). He exhibits (i) acalculia, (ii) agraphia, (iii) left-right disorientation, and (iv) finger agnosia. Complicating the issue is his obvious nonfluent aphasia (expressive dysphasia) with paraphasic errors (replacing words with associated words (e.g. says 'fork' instead of 'spoon')) and some comprehension issues.
Septic arthritis is also known as infectious arthritis, and is usually caused by bacteria, or fungus. The condition is an inflammation of a joint that's caused by infection. Typically, septic arthritis affects one large joint in the body, such as the knee or hip. Less frequently, septic arthritis can affect multiple joints
Caesarean section is the most common way to deliver a breech baby in the USA, Australia, and Great Britain. Like any major surgery, it involves risks. Maternal mortality is increased by a Caesarean section, but still remains a rare complication in the First World. Third World statistics are dramatically different, and mortality is increased significantly. There is remote risk of injury to the mother’s internal organs, injury to the baby, and severe hemorrhage requiring hysterectomy with resultant infertility. More commonly seen are problems with noncatastrophic bleeding, postoperative infection and wound healing problems. It should be added that the increase in maternal mortality rates could be slightly skewed due to the fact that Caesarean sections are often used during high-risk pregnancies and/or when mortality is already a strong possibility.
One large study has confirmed that elective cesarean section has lower risk to the fetus and a slightly increased risk to the mother, than planned vaginal delivery of the breech however elements of the methodology used have undergone some criticism.
The same birth injuries that can occur in vaginal breech birth may rarely occur in Caesarean breech delivery. A Caesarean breech delivery is still a breech delivery. However the soft tissues of the uterus and abdominal wall are more forgiving of breech delivery than the hard bony ring of the pelvis. If a Caesarean is scheduled in advance (rather than waiting for the onset of labor) there is a risk of accidentally delivering the baby too early, so that the baby might have complications of prematurity. The mother’s subsequent pregnancies will be riskier than they would be after a vaginal birth (uterine rupture). The presence of a uterine scar will be a risk factor for any subsequent pregnancies.

Over one million Americans have the sexually transmitted virus, HIV, which can lead to the deadly disease known as AIDS.
HIV can be transmitted in the sexual fluids, blood or breast milk of an infected person. HIV prevention therefore involves a wide range of activities including prevention of mother-to-child transmission, needle exchanges and harm reduction for injecting drug users, and precautions for health care workers.
Cholelithiasis involves the presence of gallstones (see the image below), which are concretions that form in the biliary tract, usually in the gallbladder. Choledocholithiasis refers to the presence of 1 or more gallstones in the common bile duct (CBD).
Emergency contraception is a method of birth control you can use if you had sex without using birth control or if your birth control method did not work correctly. You must use emergency contraception as soon as possible after unprotected sex. Emergency contraception pills are different from the abortion pill. If you are already pregnant, emergency contraception pills do not stop or harm your pregnancy. Emergency contraception has also been called the "morning-after pill," but you do not need to wait until the morning after unprotected sex to take it. Emergency contraception is not meant to be used for regular birth control. Talk to your doctor or nurse about regular birth control to help prevent pregnancy. Nearly half of all pregnancies in the United States are unplanned.1
