Common Benign Pain Syndromes--Symptoms and Etiology:
1. Non-specific musculoskeletal pain: This is the most common cause of back pain. Patients present with lumbar area pain that does not radiate, is worse with activity, and improves with rest. There may or may not be a clear history of antecedent over use or increased activity. The pain is presumably caused by irritation of the paraspinal muscles, ligaments or vertebral body articulations. However, a precise etiology is difficulty to identify.
2. Radicular Symptoms: Often referred to as "sciatica," this is a pain syndrome caused by irritation of one of the nerve roots as it exits the spinal column. The root can become inflamed as a result of a compromised neuroforamina (e.g. bony osteophyte that limits size of the opening) or a herniated disc (the fibrosis tears, allowing the propulsus to squeeze out and push on the adjacent root). Sometimes, it's not precisely clear what has lead to the irritation. In any case, patient's report a burning/electric shock type pain that starts in the low back, traveling down the buttocks and along the back of the leg, radiating below the knee. The most commonly affected nerve roots are L5 and S1.
3. Spinal Stenosis: Pain starts in the low back and radiates down the buttocks bilaterally, continuing along the backs of both legs. Symptoms are usually worse with walking and improve when the patient bends forward. Patient's may describe that they relieve symptoms by leaning forward on their shopping carts when walking in a super market. This is caused by spinal stenosis, a narrowing of the central canal that holds the spinal cord. The limited amount of space puts pressure on the nerve roots when the patient walks, causing the symptoms (referred to as neurogenic claudication). Spinal stenosis can be congenital or develop over years as a result of djd of the spine. As opposed to true claudication (pain in calfs/lower legs due to arterial insufficiency), pain resolves very quickly when person stops walking and assumes upright position. Also, peripheral pulses should be normal.
4. Mixed symptoms: In some patients, more then one process may co-exist, causing elements of more then one symptom syndrome to co-exist.

For the first few days after giving birth, a new mother’s breasts remain soft. They will produce colostrum. Colostrum, the first milk, is available in just the right amount, and is rich in immune factors that protect newborns. Sometime during the next few days, the breasts will become full, firm, warm, and perhaps tender. When this occurs, people say: “the milk is coming in!” The scientific term for this event is: engorgement. Engorgement is normal, and lasts for various periods of time depending on the individual woman. Some women experience only a day or so of mild, easy-to-manage engorgement. For other women, engorgement may be more intense, and can last from several days to two weeks.

Indications for endovascular repair of the iliac artery are: Stenosis or (short-segment) occlusion of iliac artery (TASC type A and B, TASC C lesions are controversial) with ipsilateral lower extremity ischemia (lifestyle-limiting, progressive claudication, rest pain, gangrene). Patients with asymptomatic aneurysm greater than 4 cm in diameter. An iliac aneurysm which has also increased in size by 0.5 cm in last six months. Symptomatic iliac artery aneurysms mandate endovascular (or open) repair regardless of size. Patients with long occluded lesions/poor run-off/acute limb ischemia are poor endovascular candidates.

A subdural hematoma is most often the result of a severe head injury. This type of subdural hematoma is among the deadliest of all head injuries. The bleeding fills the brain area very rapidly, compressing brain tissue. This often results in brain injury and may lead to death. Subdural hematomas can also occur after a minor head injury. The amount of bleeding is smaller and occurs more slowly. This type of subdural hematoma is often seen in older adults. These may go unnoticed for many days to weeks, and are called chronic subdural hematomas. With any subdural hematoma, tiny veins between the surface of the brain and its outer covering (the dura) stretch and tear, allowing blood to collect. In older adults, the veins are often already stretched because of brain shrinkage (atrophy) and are more easily injured.

Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries). Narrowing of the arteries prevents normal amounts of oxygen-rich blood from reaching your kidneys. Your kidneys need adequate blood flow to help filter waste products and remove excess fluids. Reduced blood flow may increase blood pressure in your whole body (systemic blood pressure) and injure kidney tissue.

This video: Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus. A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications. Treatment options for a patent ductus arteriosus include monitoring, medications and closure by cardiac catheterization or surgery.
