The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.
An intra-aortic balloon pump (IABP) is a mechanical device that helps the heart pump blood. This device is inserted into the aorta, the body's largest artery. It is a long, thin tube called a catheter with a balloon on the end of it. If you are hospitalized, your doctor may insert an IABP.
Wound healing is the process by which skin or other body tissue repairs itself after trauma. ... This process is divided into predictable phases: blood clotting (hemostasis), inflammation, tissue growth (proliferation) and tissue remodeling (maturation).
Nasal catheter YAMIK - is a new drug delivery sistem for topical treatment for sinusitis. The introduction of a large volume of the #drugsolution directly into all the paranasal #sinuses - provides new opportunities in the #treatment of #sinusitis! #YamikprocedureNasal catheter YAMIK is a new device for topical sinonasal delivery of medication during rhinosinusitis treatment. Administration of therapeutic solution with YAMIK catheter is called YAMIK procedure. The following features differs YAMIK procedure from all other topical sinonasal delivery techniques: - Medication is delivered into the all paranasal sinuses at one side of nose regardless of their involvement in the inflammatory disease. -Specific position of patient’s head. Patient should lay on the side of of the sinuses, into which solution will be administered. This position is physiological and comfortable for patients, including children and elders. The LHL position was suggested to be the most favorable position for patients to adopt - Therapeutic solutions reliably penetrates into without previous sinus surgery sinuses with natural ostia size. - Paranasal sinuses are filling with medicinal solution by gravity. To accelerate process, it is used small pressure gradient, which created by motion of syringe plunger with amplitude 1 - 2 ml during administration of solution. - It is provided contact of the whole sino-nasal mucosa with medication. - Prolonged time of the contact of sino-nasal mucosa with medicine provides administration of the therapeutically significant dose. Therapeutic solution administered into paranasal sinuses is considered as a STORE. Thanks to affect mucociliary clearance, therapeutic solution is gradually evacuated from sinuses through ostia. Thereby, prolonged nasal irrigation is performed. - Due to extended contact with saline (NaCl 0,9%), viscous colloidal pathological substance filling paranasal sinuses is dissolved. As a result, its viscosity decreases, and substance is removing by mucociliary clearance. Thereby, drainage function of the ostia are returned some time after finish YAMIK method procedure. -The procedure is performing under local anesthesia. - There is no need in active involvement of the patient. Blowing, pronouncing any sounds like “cuckoo”, holding any things and so on is unnecessary. If is performed by a qualified medical professional the procedure is more effective. - Medication contacts only with nasal passages and paranasal sinuses. Thus, it is provided topical drug therapy. - YAMIK procedure is call sinonasal delivery techniques of a therapeutic solution. It differs from nasal techniques, because medicinal solution contacts not only with nasal mucosa, but with mucous membrane of paranasal sinuses. - The only used drug formulation is a solution. - It is possible non-invasive sample extraction from mucosa of paranasal sinuses (for bacteriological, immunological, cytological and a number of others investigation methods).
The accumulation of ascitic fluid represents a state of total-body sodium and water excess, but the event that initiates the unbalance is unclear. Although many pathogenic processes have been implicated in the development of abdominal ascites, about 75% likely occur as a result of portal hypertension in the setting of liver cirrhosis, with the remainder due to infective, inflammatory, and infiltrative conditions. Three theories of ascites formation have been proposed: underfilling, overflow, and peripheral arterial vasodilation. The underfilling theory suggests that the primary abnormality is inappropriate sequestration of fluid within the splanchnic vascular bed due to portal hypertension and a consequent decrease in effective circulating blood volume. This activates the plasma renin, aldosterone, and sympathetic nervous system, resulting in renal sodium and water retention. The overflow theory suggests that the primary abnormality is inappropriate renal retention of sodium and water in the absence of volume depletion. This theory was developed in accordance with the observation that patients with cirrhosis have intravascular hypervolemia rather than hypovolemia. The most recent theory, the peripheral arterial vasodilation hypothesis, includes components of both of the other theories. It suggests that portal hypertension leads to vasodilation, which causes decreased effective arterial blood volume. As the natural history of the disease progresses, neurohumoral excitation increases, more renal sodium is retained, and plasma volume expands. This leads to overflow of fluid into the peritoneal cavity. The vasodilation theory proposes that underfilling is operative early and overflow is operative late in the natural history of cirrhosis. Although the sequence of events that occurs between the development of portal hypertension and renal sodium retention is not entirely clear, portal hypertension apparently leads to an increase in nitric oxide levels. Nitric oxide mediates splanchnic and peripheral vasodilation. Hepatic artery nitric oxide synthase activity is greater in patients with ascites than in those without ascites. Regardless of the initiating event, a number of factors contribute to the accumulation of fluid in the abdominal cavity. Elevated levels of epinephrine and norepinephrine are well-documented factors. Hypoalbuminemia and reduced plasma oncotic pressure favor the extravasation of fluid from the plasma to the peritoneal fluid, and, thus, ascites is infrequent in patients with cirrhosis unless both portal hypertension and hypoalbuminemia are present.
Osgood-Schlatter disease can cause a painful lump below the kneecap in children and adolescents experiencing growth spurts during puberty. Osgood-Schlatter disease occurs most often in children who participate in sports that involve running, jumping and swift changes of direction — such as soccer, basketball, figure skating and ballet. While Osgood-Schlatter disease is more common in boys, the gender gap is narrowing as more girls become involved with sports. Age ranges differ by sex because girls experience puberty earlier than do boys. Osgood-Schlatter disease typically occurs in boys ages 13 to 14 and girls ages 11 to 12. The condition usually resolves on its own, once the child's bones stop growing.
The examination consists of three portions: Inspection, Palpation, and Synthesis of data from these techniques In addition to palpating for size, also note the gland texture, mobility, tenderness and the presence of nodules. Inspection Inspection: Anterior Approach The patient should be seated or standing in a comfortable position with the neck in a neutral or slightly extended position. Cross-lighting increases shadows, improving the detection of masses. To enhance visualization of the thyroid, you can: Extending the neck, which stretches overlying tissues Have the patient swallow a sip of water, watching for the upward movement of the thyroid gland. quicktime video 251KB video demo from Return to the Bedside Inspection: Lateral Approach After completing anterior inspection of the thyroid, observe the neck from the side. Estimate the smooth, straight contour from the cricoid cartilage to the suprasternal notch. Measure any prominence beyond this imagined contour, using a ruler placed in the area of prominence. Palpation Note: There is no data comparing palpation using the anterior approach to the posterior approach so examiners should use the approach that they find most comfortable. Palpation: Anterior Approach placement of hands for palpatation of thyroid in anterior approach The patient is examined in the seated or standing position. Attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch. Use one hand to slightly retract the sternocleidomastoid muscle while using the other to palpate the thyroid. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland. quicktime video 454KB video demo from Return to the Bedside. Palpation: Posterior Approach placement of hands for palpatation of thyroid in posterior approach The patient is examined in the seated or standing position. Standing behind the patient, attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch. Move your hands laterally to try to feel under the sternocleidomstoids for the fullness of the thyroid. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland.
You're sneezing, coughing, and all stuffed up. It sounds and feels like a cold, alright. But as time goes on, you start to wonder. Is it turning into a sinus infection? They've got some things in common, but there are ways to tell them apart. The right ID lets your doctor get you the best treatment. What Is a Common Cold? It's an infection caused by a virus, a tiny living thing. You can't miss the symptoms: Nasal congestion Runny nose Post-nasal drip (drop-by-drop release of fluid from your nose into the back of the throat) Headache Fatigue You may also get a cough and a mild fever. The symptoms usually build, peak, and slowly disappear. Some medications can ease symptoms. For example, decongestants may decrease drainage and open the nasal passages. Pain relievers may help with fever and headache. Cough medicine may help, as well. Colds typically last from a few days to about a week or longer. Sometimes, a cold may cause swelling in the sinuses, hollow spaces in your skull that are connected to each other. The swelling can prevent the flow of mucus.
ACE inhibitors Email this page to a friend Print Facebook Twitter Google+ Angiotensin-converting enzyme (ACE) inhibitors are medicines. They treat heart, blood vessel, and kidney problems. How ACE inhibitors help ACE inhibitors are used to treat heart disease. These medicines make your heart work less hard by lowering your blood pressure. This keeps some kinds of heart disease from getting worse. Most people who have heart failure take these medicines. These medicines treat high blood pressure, strokes, or heart attacks. They may help lower your risk for stroke or heart attack. They are also used to treat diabetes and kidney problems. This can help keep your kidneys from getting worse. If you have these problems, ask your health care provider if you should be taking these medicines.
Oral therapy has potential for symptom relief. It has the advantage of no surgery. Disadvantages include ongoing medication therapy, risks of side effects, high out of pocket cost, and sometimes over time effectiveness diminishes. Certain men also do not like to take medications. This is the most common way to treat BPH. Medicines like Flomax, Cardura, Hytrin and Uroxatral have proven to be effective in the treatment of most cases. Alpha Blockers relieve the obstruction by trying to stop the process by which the construction occurs. They basically relax the smooth muscle cells in the prostate to relieve urinary obstruction. Like most medicines side effects can occur. They are mild in most cases and include dizziness on standing, feeling fatigued, loss of ability to ejaculate with orgasm.
Microscopic polyangiitis (MPA) is vasculitis of small vessels. It was initially considered as a microscopic form of polyarteritis nodosa (PAN). In 1990, the American College of Rheumatology developed classification criteria for several types of systemic vasculitis but did not distinguish between polyarteritis nodosa and microscopic polyarteritis nodosa. [1] In 1994, a group of experts held an international consensus conference in Chapel Hill, North Carolina, to attempt to redefine the classification of small vessel vasculitides. [2, 3]
Diabetes insipidus (die-uh-BEE-teze in-SIP-uh-dus) is an uncommon disorder that causes an imbalance of water in the body. This imbalance leads to intense thirst even after drinking fluids (polydipsia), and excretion of large amounts of urine (polyuria). While the names diabetes insipidus and diabetes mellitus sound similar, they're not related. Diabetes mellitus — which can occur as type 1 or type 2 — is the more common form of diabetes. There's no cure for diabetes insipidus, but treatments are available to relieve your thirst and normalize your urine output.
-MEN1 syndrome is composed of hyperparathyroidism, gastrinoma (pancreatic tumor) and pituitary tum or(remember the 3 Ps). Hyperparathyroidism in MEN1 is caused by hyperplasia of the parathyroid glands. Removal of 3 1/2 glands or total parathyroidectomy with autotransplantation is necessary.
