Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. You may have sleep apnea if you snore loudly, and you feel tired even after a full night's sleep. The main types of sleep apnea are: Obstructive sleep apnea, the more common form that occurs when throat muscles relax. Central sleep apnea, which occurs when your brain doesn't send proper signals to the muscles that control breathing. Complex sleep apnea syndrome, also known as treatment-emergent central sleep apnea, occurs when someone has both obstructive sleep apnea and central sleep apnea. If you think you might have any form of sleep apnea, see your doctor. Treatment can ease your symptoms and may help prevent heart problems and other complications.
Dr. David Rivadeneira from Stony Brook University in Stony Brook, NY will host a panel discussion on how to obtain improved outcomes during open surgery through the application of advanced techniques and technologies, including the new LigaSure Impact™ instrument. "It provides excellent and reliable hemostasis on major blood vessels, but the big advancement is that it is faster than traditional techniques and leaves no foreign material behind."
The program will begin with a brief introduction of the topic, followed by video presentation of two procedures, a right hemicolectomy and a sigmoid colectomy. Dr. Rivadeneira will discuss the techniques that he uses. "You'll be able to see the impact of applying multifunctional energy-based instruments to enable rapid and reliable dissection of the mesentery and ligation of colonic blood supply. This is particularly evident on tough diverticular cases, where it works very well with complicated tissue." Joining Dr. Rivadeneira, to review and discuss the cases, will be Dr. Sang Lee from Weill Cornell Medical College, NY.

Knee replacement, commonly known as complete knee replacement or knee arthroplasty, is a surgical treatment that resurfaces a knee that has been destroyed by arthritis. The extremities of the bones that make up the knee joint, as well as the kneecap, are capped with metal and plastic pieces. Someone with severe arthritis or a major knee injury may benefit from this procedure.
The knee joint can be affected by a variety of arthritis forms. The degradation of joint cartilage and neighboring bone in the knees can be caused by osteoarthritis, a degenerative joint disease that primarily affects middle-aged and older persons. Rheumatoid arthritis produces pain and stiffness by inflaming the synovial membrane and resulting in an excess of synovial fluid. Traumatic arthritis, or arthritis caused by an injury, can harm the joints.
The purpose of knee replacement surgery is to resurface damaged areas of the knee joint and cure knee discomfort that has not responded to prior therapies.
Neurotransmitter 3D Animation

Neurotransmitters are endogenous chemicals which transmit signals from a neuron to a target cell across a synapse. Neurotransmitters are packaged into synaptic vesicles clustered beneath the membrane on the presynaptic side of a synapse, and are released into the synaptic cleft, where they bind to receptors in the membrane on the postsynaptic side of the synapse. Release of neurotransmitters usually follows arrival of an action potential at the synapse, but may also follow graded electrical potentials. Low level "baseline" release also occurs without electrical stimulation. Neurotransmitters are synthesized from plentiful and simple precursors, such as amino acids, which are readily available from the diet and which require only a small number of biosynthetic steps to convert. The chemical identity of neurotransmitters is often difficult to determine experimentally. For example, it is easy using an electron microscope to recognize vesicles on the presynaptic side of a synapse, but it may not be easy to determine directly what chemical is packed into them. The difficulties led to many historical controversies over whether a given chemical was or was not clearly established as a transmitter. In an effort to give some structure to the arguments, neurochemists worked out a set of experimentally tractable rules. According to the prevailing beliefs of the 1960s, a chemical can be classified as a neurotransmitter if it meets the following conditions: * There are precursors and/or synthesis enzymes located in the presynaptic side of the synapse. * The chemical is present in the presynaptic element. * It is available in sufficient quantity in the presynaptic neuron to affect the postsynaptic neuron; * There are postsynaptic receptors and the chemical is able to bind to them. * A biochemical mechanism for inactivation is present. There are many different ways to classify neurotransmitters. Dividing them into amino acids, peptides, and monoamines is sufficient for some classification purposes. Major neurotransmitters: * Amino acids: glutamate, aspartate, D-serine, γ-aminobutyric acid (GABA), glycine * Monoamines and other biogenic amines: dopamine (DA), norepinephrine (noradrenaline; NE, NA), epinephrine (adrenaline), histamine, serotonin (SE, 5-HT), melatonin * Others: acetylcholine (ACh), adenosine, anandamide, nitric oxide, etc. In addition, over 50 neuroactive peptides have been found, and new ones are discovered regularly. Many of these are "co-released" along with a small-molecule transmitter, but in some cases a peptide is the primary transmitter at a synapse. β-endorphin is a relatively well known example of a peptide neurotransmitter; it engages in highly specific interactions with opioid receptors in the central nervous system. Single ions, such as synaptically released zinc, are also considered neurotransmitters by some[by whom?], as are some gaseous molecules such as nitric oxide (NO) and carbon monoxide (CO). These are not classical neurotransmitters by the strictest definition, however, because although they have all been shown experimentally to be released by presynaptic terminals in an activity-dependent way, they are not packaged into vesicles. By far the most prevalent transmitter is glutamate, which is excitatory at well over 90% of the synapses in the human brain. The next most prevalent is GABA, which is inhibitory at more than 90% of the synapses that do not use glutamate. Even though other transmitters are used in far fewer synapses, they may be very important functionally—the great majority of psychoactive drugs exert their effects by altering the actions of some neurotransmitter systems, often acting through transmitters other than glutamate or GABA. Addictive drugs such as cocaine and amphetamine exert their effects primarily on the dop

A pilonidal sinus (PNS) is a small cyst or abscess that occurs in the cleft at the top of the buttocks. A PNS usually contains hair, dirt, and debris. It can cause severe pain and can often become infected. If it becomes infected, it may ooze pus and blood and have a foul odor. A PNS is a condition that mostly affects men and is also common in young adults. It’s also more common in people who sit a lot, like cab drivers.

Wound closure techniques have evolved from the earliest development of suturing materials to comprise resources that include synthetic sutures, absorbables, staples, tapes, and adhesive compounds. The engineering of sutures in synthetic material along with standardization of traditional materials (eg, catgut, silk) has made for superior aesthetic results. Similarly, the creation of topical skin adhesives (the monomer 2-octyl cyanoacrylate), surgical staples, and tapes to substitute for sutures has supplemented the armamentarium of wound closure techniques. Aesthetic closure of a wound, whether traumatic or surgically induced, is based on knowledge of healing mechanisms and skin anatomy (see the image below), as well as an appreciation of suture material and closure technique. Choosing the proper materials and wound closure technique ensures optimal healing.[1]
Dr. Horacio Asbun, Mayo Clinic in Florida, explains the Whipple procedure using this animated graphic of a pancreas. Cancer of the pancreas affects 45,000 people every year in the U.S., and it is the fourth leading cause of cancer-related deaths. The five-year overall survival rate if a tumor is detected early and surgically removed is 22 percent, versus 6 percent without early detection and surgery.
