ADH's job is to act on the kidneys to promote water reabsorption. In this lesson, we'll compare and contrast diabetes insipidus, or DI, in which there is too little ADH, and syndrome of inappropriate antidiuretic hormone secretion , or SIADH, in which there is too much ADH.

he appendix is a long narrow tube (a few inches in length) that attaches to the first part of the colon. It is usually located in the lower right quadrant of the abdominal cavity. The appendix produces a bacteria destroying protein called immunoglobulins, which help fight infection in the body. Its function, however, is not essential. People who have had appendectomies do not have an increased risk toward infection. Other organs in the body take over this function once the appendix has been removed.

Decompression is a surgical procedure that is performed to alleviate pain caused by pinched nerves (neural impingement). During a lumbar decompression back surgery, a small portion of the bone over the nerve root and/or disc material from under the nerve root is removed to give the nerve root more space and provide a better healing environment. There are two common types of spine surgery decompression procedures: Microdiscectomy Lumbar Microdiscectomy Microdiscectomy Surgery Video A microdiscectomy (a microdecompression) is typically performed for pain from a lumbar herniated disc. The surgery is considered reliable for leg pain caused by the herniated disc, most commonly called sciatica by patients, and most commonly referred to by medical practitioners as a radiculopathy.

Surgical technique: A 3cm skin incision under spinal or general anesthesia, depending on the patients’ preference, starts half way the line between the superior anterior iliac spine towards the midline in a 30° angle to the pubic tubercle. Scarpa’s fascia is opened as well as the external obliq...ue aponeurosis. By using this skin line incision the internal ring will be immediately visualized. Although it is important to look for both direct and indirect hernias evaluating the groin, we do not taper the cord and directly evaluate the ring for indirect hernias. In case of an indirect hernia the sac is reduced or resected according to the preference of the surgeon and the preperitoneal space is entered bluntly through the dilated internal ring. In case of a direct hernia the approach slightly differs. One could prefer to open the transversalis fascia through the internal ring over a few centimeters or you can open the fascia more medially, at the site of the direct hernia. As primary point of concern the epigastric vessels should be identified and retracted softly upwards. Then a gauze can be introduced into the preperitoneal space and by doing so most of the space needed medially will be created. Then one can already palpate Cooper’s ligament and the pubic bone. Laterally to the internal ring more digital dissection is needed to create just the appropriate space for the mesh. By placing the mesh it is important not to introduce the mesh too medially. Laterally of the internal ring an adequate overlap of the mesh is necessary, especially in indirect hernias. No splitting of the mesh seems necessary. The patient will be asked to strain and push on the ring to control its place and to check adequate spreading of the mesh to cover the whole myopectineum of Fruchaud. One single stitch of vicryl 3/0 is placed taking both the fascia transversalis and the mesh.

An unnamed Russian scientist has introduced the concept of a device that attaches to the wall of the artery. It would first stop blood flow to the area to prevent breakaway plaque. A drill would then scrape the plaque from the artery wall. The procedure of treating plaque buildup could include bypass surgery, stent replacement and balloon angioplasty. Since the plaques are of different types and locations in the body, the inventor proposed using different types of cutting mills.

Myelodysplastic syndromes are a group of cancers in which immature blood cells in the bone marrow do not mature or become healthy blood cells. In a healthy person, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time.Aug 12, 2015

Among common cancers, pancreatic cancer has one of the poorest prognoses. Because pancreatic cancer often grows and spreads long before it causes any symptoms, only about 6% of patients are still alive five years after diagnosis. For some pancreatic patients, however, a complex surgery known as the Whipple procedure may extend life and could be a potential cure. Those who undergo a successful Whipple procedure may have a five-year survival rate of up to 25%.

Lysosomal storage diseases (LSDs; /ˌlaɪsəˈsoʊməl/) are a group of approximately 50 rare inherited metabolic disorders that result from defects in lysosomal function. Lysosomes are sacs of enzymes within cells that digest large molecules and pass the fragments on to other parts of the cell for recycling.

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.

Binding and Fusion: HIV begins its life cycle
when it binds to a CD4 receptor and one of two
co-receptors on the surface of a CD4+
Tlymphocyte. The virus then fuses with the host
cell. After fusion, the virus releases RNA, its
genetic material, into the host cell.

Reverse Transcription: An HIV enzyme
called reverse transcriptase converts the singlestranded HIV RNA to double-stranded HIV DNA.

Integration: The newly formed HIV DNA
enters the host cell's nucleus, where an HIV
enzyme called integrase "hides" the HIV DNA
within the host cell's own DNA. The integrated
HIV DNA is called provirus. The provirus may
remain inactive for several years, producing few or
no new copies of HIV

Transcription: When the host cell receives a
signal to become active, the provirus uses a host
enzyme called RNA polymerase to create copies of
the HIV genomic material, as well as shorter
strands of RNA called messenger RNA (mRNA).
The mRNA is used as a blueprint to make long
chains of HIV proteins.

Assembly: An HIV enzyme called protease cuts
the long chains of HIV proteins into smaller
individual proteins. As the smaller HIV proteins
come together with copies of HIV's RNA genetic
material, a new virus particle is assembled.

Budding: The newly assembled virus pushes out
("buds") from the host cell. During budding, the new
virus steals part of the cell's outer envelope. This
envelope, which acts as a covering, is studded with
protein/sugar combinations called HIV
glycoproteins. These HIV glycoproteins are
necessary for the virus to bind CD4 and coreceptors. The new copies of HIV can now move
on to infect other cells.

Sporotrichosis (also known as "rose gardener's disease") is a disease caused by the infection of the fungus Sporothrix schenckii. This fungal disease usually affects the skin, although other rare forms can affect the lungs, joints, bones, and even the brain.
