Cardiac arrest – Wikipedia

Cardiac arrestSynonymsCardiopulmonary arrest, circulatory arrest, sudden cardiac arrest (SCA), sudden cardiac death (SCD)[1]CPR being administered during a simulation of cardiac arrest.SpecialtyCardiologySymptomsLoss of consciousness, abnormal or no breathing[1][2]Usual onsetOlder age[3]CausesCoronary artery disease, major blood loss, lack of oxygen, very low potassium, heart failure[4]Diagnostic methodFinding no pulse[1]PreventionNot smoking, physical activity, maintaining a healthy weight[5]TreatmentCardiopulmonary resuscitation (CPR), defibrillation[6]PrognosisAverage survival 8%[7]Frequency13 per 10,000 people per year (outside hospital in the US)[8] Cardiac arrest is a sudden loss of blood flow resulting from the failure of the heart to effectively pump.[9] Symptoms include loss of consciousness and abnormal or absent breathing.[1][2] Some individuals may experience chest pain, shortness of breath, or nausea before cardiac arrest.[2] If not treated within minutes, it typically leads to death.[9] The most common cause of cardiac arrest is coronary artery disease.[4] Less common causes include major blood loss, lack of oxygen, very low potassium, heart failure, and intense physical exercise.[4] A number of inherited disorders may also increase the risk including long QT syndrome.[4] The initial heart rhythm is most often ventricular fibrillation.[4] The diagnosis is confirmed by finding no pulse.[1] While a cardiac arrest may be caused by heart attack or heart failure, these are not the same.[9] Prevention includes not smoking, physical activity, and maintaining a healthy weight.[5] Treatment for cardiac arrest includes immediate cardiopulmonary resuscitation (CPR) and, if a shockable rhythm is present, defibrillation.[6] Among those who survive, targeted temperature management may improve outcomes.[10][11] An implantable cardiac defibrillator may be placed to reduce the chance of death from recurrence.[5] In the United States, cardiac arrest outside hospital occurs in about 13 per 10,000 people per year (326,000 cases).[8] In hospital cardiac arrest occurs in an additional 209,000.[8] Cardiac arrest becomes more common with age.[3] It affects males more often than females.[3] The percentage of people who survive with treatment is about 8%.[7] Many who survive have significant disability.[7] However, many American television programs have portrayed unrealistically high survival rates of 67%.[7] Cardiac arrest is preceded by no warning symptoms in approximately 50 percent of people.[12] For those who do experience symptoms, they will be non-specific, such as new or worsening chest pain, fatigue, blackouts, dizziness, shortness of breath, weakness and vomiting.[13] When cardiac arrest occurs, the most obvious sign of its occurrence will be the lack of a palpable pulse in the victim.

Ulcerative colitisEndoscopic image of a colon affected by ulcerative colitis. The internal surface of the colon is blotchy and broken in places.SpecialtyGastroenterologySymptomsAbdominal pain, diarrhea mixed with blood, weight loss, fever, anemia[1]ComplicationsMegacolon, inflammation of the eye, joints, or liver, colon cancer[1][2]Usual onset1530 years or > 60 years[1]DurationLong term[1]CausesUnknown[1]Diagnostic methodColonoscopy with tissue biopsies[1]Differential diagnosisDysentery, Crohn's disease, ischemic colitis[3]TreatmentDietary changes, medication, surgery[1]MedicationSulfasalazine, mesalazine, steroids, immunosuppressants such as azathioprine, biological therapy[1]FrequencyUp to 5 per 1000 people[4]Deaths47,400 together with Crohn's (2015)[5] Ulcerative colitis (UC) is a long-term condition that results in inflammation and ulcers of the colon and rectum.[1][6] The primary symptoms of active disease are abdominal pain and diarrhea mixed with blood.[1] Weight loss, fever, and anemia may also occur.[1] Often, symptoms come on slowly and can range from mild to severe.[1] Symptoms typically occur intermittently with periods of no symptoms between flares.[1] Complications may include megacolon, inflammation of the eye, joints, or liver, and colon cancer.[1][2] The cause of UC is unknown.[1] Theories involve immune system dysfunction, genetics, changes in the normal gut bacteria, and environmental factors.[1][7] Rates tend to be higher in the developed world with some proposing this to be the result of less exposure to intestinal infections, or to a Western diet and lifestyle.[6][8] The removal of the appendix at an early age may be protective.[8] Diagnosis is typically by colonoscopy with tissue biopsies.[1] It is a kind of inflammatory bowel disease (IBD) along with Crohn's disease and microscopic colitis.[1] Dietary changes, such as maintaining a high-calorie diet or lactose-free diet, may improve symptoms.[1] Several medications are used to treat symptoms and bring about and maintain remission, including aminosalicylates such as mesalazine or sulfasalazine, steroids, immunosuppressants such as azathioprine, and biologic therapy.[1] Removal of the colon by surgery may be necessary if the disease is severe, does not respond to treatment, or if complications such as colon cancer develop.[1] Removal of the colon and rectum can cure the disease.[1][8] Together with Crohn's disease, about 11.2 million people were affected as of 2015.[9] Each year it newly occurs in 1 to 20 per 100,000 people, and 5 to 500 per 100,000 individuals are affected.[6][8] The disease is more common in North America and Europe than other regions.[8] Often it begins in people aged 15 to 30 years, or among those over 60.[1] Males and females appear to be affected in equal proportions.[6] It has also become more common since the 1950s.[6][8] Together, ulcerative colitis and Crohn's disease affect about a million people in the United States.[10] With appropriate treatment the risk of death appears the same as that of the general population.[2] The first description of ulcerative colitis occurred around the 1850s.[8] The clinical presentation[13] of ulcerative colitis depends on the extent of the disease process. Patients usually present with diarrhea mixed with blood and mucus, of gradual onset that persists for an extended period (weeks) Continue reading
