Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles โ€“ malleus, incus, stapes) in the middle ear. The last bone in this chain 'knocks' on the membrane window of the cochlea and makes the fluid in the cochlea move.

An ileostomy is an opening in the belly (abdominal wall) thatโ€™s made during surgery. The end of the ileum (the lowest part of the small intestine) is brought through this opening to form a stoma, usually on the lower right side of the abdomen. A Wound Ostomy Continence nurse (WOCN or WOC nurse) or the surgeon will figure out the best location for your stoma. (A WOC nurse is a specially trained registered nurse who takes care of and teaches ostomy patients. This nurse may also be called an ostomy nurse.)

Tension pneumothorax develops when a lung or chest wall injury is such that it allows air into the pleural space but not out of it (a one-way valve). As a result, air accumulates and compresses the lung, eventually shifting the mediastinum, compressing the contralateral lung, and increasing intrathoracic pressure enough to decrease venous return to the heart, causing shock. These effects can develop rapidly, particularly in patients undergoing positive pressure ventilation.

Norepinephrine is synthesized from dopamine by dopamine ฮฒ-hydroxylase.[7] It is released from the adrenal medulla into the blood as a hormone, and is also a neurotransmitter in the central nervous system and sympathetic nervous system where it is released from noradrenergic neurons.

The pathobiology of MM is complex and the root underlying cause of myeloma is the multistep genetic changes in the postgerminal center B cell. In addition, the bone marrow microenvironment plays a crucial role.[2] The interaction between myeloma cells and the microenvironment is mediated through adhesive interactions via cell-surface receptors, paracrine loops involving several cytokines, such as IL-6, VEGF and IL-10, and suppression of cell-mediated immunity.[2โ€“4] IMiDs modulate many of these interactions leading to decreased myeloma cell growth and survival. Thalidomide was the first IMiD introduced to treat MM. It was initially synthesized in Germany in the late 1950s to treat insomnia and morning sickness. It was withdrawn from the market in 1961 because of its teratogenic effects. Its immunomodulatory properties were realized when it was observed to improve erythema nodosum leprosum, a painful immunologic reaction of leprosy, leading to its approval by the FDA in 1998 with tight prescribing and marketing regulations. Subsequent research showed the diverse mechanism of action of thalidomide including its immunomodulatory effect by inhibition of de novo IgM antibody synthesis,[5] modulation of the T-cell subset by increasing the T-helper cells, inhibitory effects on the TNF-ฮฑ and antiangiogenic activity leading to its use in MM. Significantly higher response rates in combination with dexamethasone led to its approval in the treatment of newly diagnosed MM in 2006. Lenalidomide, a second-generation IMiD, was developed from the structural backbone of the thalidomide molecule by the addition of an amino group (NH2-) at position 4 of the phthaloyl ring and removal of the carbonyl group (C = O) of the 4-amino-substituted phthaloyl ring (Table 1).[6] In addition to immunomodulatory effects, other mechanisms of action have been described such as direct cytotoxicity via induction of apoptosis, inhibition of cell adhesion molecules and inhibition of growth signals that promote bone marrow angiogenesis

Hysterectomy is the surgical removal of the uterus. It ends menstruation and the ability to become pregnant. Depending on the reason for the surgery, a hysterectomy may also involve the removal of other organs and tissues such as the ovaries and/or fallopian tubes.

Types of multiple myeloma. Multiple myeloma is the most common type of plasma cell cancer. The bones and bone marrow are the main sites where myeloma cells (abnormal plasma cells) are produced. The myeloma cells can form tumours, called plasmacytomas, in many bones in the body.
