Venipuncture: Learning how to start an IV
Venipuncture: Learning how to start an IV Mohamed Ibrahim 10,958 Views • 2 years ago

IV cannulation is a skill that has scared a lot of student nurses and even professionals. Perhaps it’s because IV insertion is an invasive procedure, and nurses are too worried that they might hurt their patients. Or maybe it’s because they are just clueless about IV therapy do’s and don’ts–things that one can only fully understand through constant practice.

Cytomegalovirus in solid organ transplant recipients
Cytomegalovirus in solid organ transplant recipients samer kareem 1,505 Views • 2 years ago

Cytomegalovirus (CMV) continues to have a tremendous impact in solid organ transplantation despite remarkable advances in its diagnosis, prevention and treatment. It can affect allograft function and increase patient morbidity and mortality through a number of direct and indirect effects. Patients may develop asymptomatic viremia, CMV syndrome or tissue-invasive disease. Late-onset CMV disease continues to be a major problem in high-risk patients after completion of antiviral prophylaxis. Emerging data suggests that immunologic monitoring may be useful in predicting the risk of late onset CMV disease. There is now increasing interest in the development of an effective vaccine for prevention. Novel antiviral drugs with unique mechanisms of action and lesser toxicity are being developed. Viral load quantification is now undergoing standardization, and this will permit the generation of clinically relevant viral thresholds for the management of patients. This article provides a brief overview of the contemporary epidemiology, clinical presentation, diagnosis, prevention and treatment of CMV infection in solid organ transplant recipients.

What Is A Gastric Ulcer?
What Is A Gastric Ulcer? samer kareem 2,372 Views • 2 years ago

What Causes Ulcers? No single cause has been found for ulcers. However, it is now clear that an ulcer is the end result of an imbalance between digestive fluids in the stomach and duodenum. Most ulcers are caused by an infection with a type of bacteria called Helicobacter pylori (H. pylori). Factors that can increase your risk for ulcers include: Use of painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, naproxen (Aleve, Anaprox, Naprosyn, and others), ibuprofen (Motrin, Advil, some types of Midol, and others), and many others available by prescription; even safety-coated aspirin and aspirin in powered form can frequently cause ulcers. Excess acid production from gastrinomas, tumors of the acid producing cells of the stomach that increases acid output (seen in Zollinger-Ellison syndrome) Excessive drinking of alcohol Smoking or chewing tobacco Serious illness Radiation treatment to the area What Are the Symptoms of an Ulcer? An ulcer may or may not have symptoms. When symptoms occur, they may include: A gnawing or burning pain in the middle or upper stomach between meals or at night Bloating Heartburn Nausea or vomiting In severe cases, symptoms can include: Dark or black stool (due to bleeding) Vomiting blood (that can look like "coffee-grounds") Weight loss Severe pain in the mid to upper abdomen

IgA deficiency
IgA deficiency samer kareem 3,162 Views • 2 years ago

Selective immunoglobulin A deficiency (SIgAD) is a primary immunodeficiency disease and is the most common of the primary antibody deficiencies.[1] Total immunoglobulin A deficiency (IgAD) is defined as an undetectable serum immunoglobulin A (IgA) level at a value < 5 mg/dL (0.05 g/L) in humans. Partial IgAD refers to detectable but decreased IgA levels that are more than 2 standard deviations below normal age-adjusted means.[2, 3] IgAD is commonly associated with normal B lymphocytes in peripheral blood, normal CD4+ and CD8+ T cells, and, usually, normal neutrophil and lymphocyte counts. Anti-IgA autoantibodies of the IgG and/or IgE isotype may be present. Peripheral blood may also be affected by autoimmune cytopenias, eg, autoimmune thrombocytopenia,[4, 5] and patients may have other autoimmune phenomena. IgA was first identified by Graber and Williams in 1952; ten years later, the first patients with IgAD were described. IgAD is a heterogeneous disorder, and the results of intensive study are beginning to elucidate genetic loci and molecular pathogenesis that contribute to various subtypes of this disorder. Several lines of evidence suggest that, in many cases, IgAD and common variable immunodeficiency (CVID) have a common pathogenesis, which is discussed further in Pathophysiology. Other data indicate different genetic risk factors. Family studies show variable inheritance patterns. Familial inheritance of IgAD occurs in approximately 20% of cases,[6] and, within families, IgAD and CVID are associated.[7, 8] Many IgAD patients are asymptomatic (ie, "normal" blood donors) and are identified by finding a laboratory abnormality, without any apparent associated clinical disease. Some patients with IgAD may have the following associated conditions: (1) deficits in one or more immunoglobulin G (IgG) subclasses (this accounts for 20-30% of IgA-deficient patients, many of whom may have total IgG levels within the normal range) or (2) a deficient antibody response to pneumococcal immunization (specific polysaccharide antibody deficiency [SPAD]). Some patients with IgAD later develop CVID, and family members of patients with CVID may have only selective IgAD. Characterization of the receptor for the transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI), encoded by the gene TNFRSF13B ( tumor necrosis factor receptor superfamily member 13B), suggests that people with the C104, A181E, and ins204A variants may be at risk for IgAD that progresses to CVID.[9] Primary IgAD is permanent, and below-normal levels have been noted to remain static and persist after 20 years of observation.[10] A recent report documents a rare case of reversion.[11] Environmental factors such as drugs or infections can cause IgAD, but this form is reversible in more than half the cases (see Causes). Although individuals with IgAD have largely been considered healthy, recent studies indicate a higher rate of symptoms. A 20-year follow-up study that compared 204 healthy blood donors with incidentally identified IgAD to 237 healthy subjects with normal IgA levels demonstrated that 80% of IgAD donors and 50% of control subjects had episodes of infections, drug allergy, or autoimmune or atopic disease. Severe respiratory tract infections occurred in 26% of IgAD subjects, in 24% of subjects with decreased IgA levels, and in 8% of control subjects; however, the incidence of life-threatening infections was not increased. IgAD is more common in adult patients with chronic lung disease than in healthy age-matched control subjects.[12] Patients with IgAD are at some increased risk of developing severe reactions after receiving blood products.[13, 14, 15] IgG anti-IgA antibodies may cause severe transfusion reactions if patients with IgAD are given whole blood; therefore, IgA-poor blood or washed red cells are preferred for those patients. IgA-deficient patients with immunoglobulin E (IgE)–class anti-IgA antibodies are at risk for anaphylaxis if they receive blood or intravenous immunoglobulin, but this situation is extremely rare. Individuals with such an unusual profile should receive only low IgA intravenous immunoglobulin preparations. However, caution must be used when administering IGIV to patients with IgAD if their anti-IgA status is unknown. A history devoid of previous blood product administration does not exclude the possibility of anti-IgA antibodies or adverse reactions. Fortunately, appropriate precautions can significantly reduce morbidity (see Treatment). Blood banks can use a simple ELISA screening approach to establish an IgAD blood donor poo

Megacolon
Megacolon samer kareem 3,029 Views • 2 years ago

Megacolon, as well as megarectum, is a descriptive term. It denotes dilatation of the colon that is not caused by mechanical obstruction.[1, 2] Although the definition of megacolon has varied in the literature, most researchers use the measurement of greater than 12 cm for the cecum as the standard. Because the diameter of the large intestine varies, the following definitions would also be considered: greater than 6.5 cm in the rectosigmoid region and greater than 8 cm for the ascending colon. Megacolon can be divided into the following 3 categories: Acute megacolon ( pseudo-obstruction) Chronic megacolon, which includes congenital, acquired, and idiopathic causes Toxic megacolon

How To Increase Brain Power, How To Increase Brain Activity, How To Boost Your Concentration--- http://brain-revitalizer.info-pro.co --- Improve Concentration, Ask anyone today what they have a hard time with and more often than not they are likely to cite trouble focusing or concentrating. With laptops, smart phones, television, GPS systems and social media, it is hard to block out all the distractions when you need to focus on something specific. Attention deficit disorder may be one of the most popular excuses for our lack of concentration, but it's not an entirely accurate diagnosis since many of us simply aren't training our brains the right way to improve our focus. Concentration is necessary just to make it through a typical workday. From driving and working to shopping and cooking, focus is essential in order to get tasks accomplished. Unfortunately many of us have a hard time zoning in on a specific project and seeing it through to completion. Being easily distracted is not necessarily a disorder but it will keep you from managing your time wisely and getting done the important things that need your attention. There are several ways people can improve their concentration, including strategic brain games and exercises, along with guided meditation and brainwave entrainment. Research has shown that the more a person trains their brain in specific skill sets, the better one can get at cognitive thinking, problem solving and memorization. Using computer generated pulses, or isochronic tones, during brain entrainment meditation is another way to synchronize your brain's frequencies so you can operate on a fast or slow frequency that will assist in achieving states of productivity or relaxation. As we all know, when we are relaxed our concentration and decision making are much better than if we are under stress or hurried. Being able to tap in to specific Alpha, Theta and Delta waves allows us to synchronize our brainwaves with sound pulses so we can be more focused on specific projects and tasks. But YOU can be different! You can use Genius Brain Power to empower your brain so that you come alive with more energy, learn quicker, think more creatively, focus on your work like never before and drastically reduce stress with amazingly deep states of relaxation and meditation. click here: http://brain-revitalizer.info-pro.co

Endometrial Polyp
Endometrial Polyp samer kareem 20,659 Views • 2 years ago

Uterine polyps are growths attached to the inner wall of the uterus that extend into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps, also known as endometrial polyps. These polyps are usually noncancerous (benign), although some can be cancerous or can eventually turn into cancer (precancerous polyps). Uterine polyps range in size from a few millimeters — no larger than a sesame seed — to several centimeters — golf-ball-size or larger. They attach to the uterine wall by a large base or a thin stalk.

The Placenta
The Placenta samer kareem 3,996 Views • 2 years ago

What does the placenta do? The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it. In most pregnancies, the placenta attaches at the top or side of the uterus.

Tooth Filling Procedure
Tooth Filling Procedure samer kareem 6,789 Views • 2 years ago

A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a filling material. By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).

Aneurysm Clip
Aneurysm Clip samer kareem 1,438 Views • 2 years ago

The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades. Clips are made of titanium and remain on the artery permanently.
