Dr. Linder is removing a patients breast implants after having five breast augmentations from three previous surgeons. She has baker 4 capsular contracture and is look forward to having them removed. The most common reasons for removing a breast implant include; heath reasons such as back pain, reoccurring complications and the desire for a different shape or size. For implant removal surgery, Dr. Linder makes an inframammary incision (along the breast crease). The implant can be removed intact, or it may need to be punctured before removal. An antibiotic solution is used to irrigate the breast pocket after implant removal. For more information about breast implant removal go to www.implantremoval.net or call Dr. Linder's office at 310-275-4513

Acute respiratory distress syndrome is characterised by rapid onset dyspnea, bilateral infiltrates on chest x-ray and respiratory failure. This may be due to conditions which directly affect the lung such as pneumonia, aspiration and near drowning. It may also be due to indirect lung injury, as in conditions like sepsis, pancreatitis, trauma and poisoning. The diagnostic criteria of ARDS, often described as the Berlin criteria is discussed in this presentation along with various management aspects of ARDS including ventilation strategies and use of antibiotics and diuretics. Finally prognostic features and alternative strategies are also discussed.

Extremely funny, and very in-depth look at all the parts and pieces of your blood.

Paracentesis is a procedure to take out fluid that has collected in the belly (peritoneal fluid). This fluid buildup is called ascites . Ascites may be caused by infection, inflammation, an injury, or other conditions, such as cirrhosis or cancer. The fluid is taken out using a long, thin needle put through the belly.

This minimally invasive surgical procedure repairs the valve without removing the old, damaged valve. Instead, it wedges a replacement valve into the aortic valve’s place. The surgery may be called a transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI).

Hypoglycemia is a common and serious medical emergency which may occur in both daibetic and non-diabetic patients. The signs and symptoms of hypoglycaemia may be present in many individuals, but may also be masked in several individuals due to a condition called hypoglycaemia induced autonomic failure. This presentation aims to deal with the causes, clinical features, diagnosis and management of various causes of hypoglycaemia. The causes of hypoglycaemia may be divided into hypoglycaemia in ill or medicated individuals and hypoglycaemia in previously asymptomatic individuals. A variety of causes are discussed under both headings. Management of hypoglycaemia is also discussed in detail. There is also a brief discussion about management of insulinoma.

New flu vaccines are released every year to keep up with rapidly adapting flu viruses. Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. After vaccination, your immune system produces antibodies that will protect you from the vaccine viruses.

For this surgery, your doctor makes a large incision in the abdomen to expose the aorta. Once he or she has opened the abdomen, a graft can be used to repair the aneurysm. Open repair remains the standard procedure for an abdominal aortic aneurysm repair. Endovascular aneurysm repair (EVAR).

With keratoconus, the clear, dome-shaped tissue that covers the eye (cornea) thins and bulges outward into a cone shape. Its cause is unknown. Symptoms first appear during puberty or the late teens and include blurred vision and sensitivity to light and glare. Vision can be corrected with glasses or contact lenses early on. Advanced cases may require a cornea transplant.

A young patient undergoes state of the art robotic surgery for Ovarian Cancer and Endometrial Cancer in Chicago, IL. The surgery is performed by noted gynecologic oncologist and expert robotic surgeon M. Patrick Lowe MD. Dr Lowe has been performing robotic surgery since 2006 and is one of a few gynecologic oncologist in the United States who utilizes robotics for ovarian cancer.

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
