Pancreatitis is inflammation in the pancreas. The pancreas is a long, flat gland that sits tucked behind the stomach in the upper abdomen. The pancreas produces enzymes that assist digestion and hormones that help regulate the way your body processes sugar (glucose). Pancreatitis can occur as acute pancreatitis — meaning it appears suddenly and lasts for days. Or pancreatitis can occur as chronic pancreatitis, which describes pancreatitis that occurs over many years. Mild cases of pancreatitis may go away without treatment, but severe cases can cause life-threatening complications.
Retropharyngeal abscess (RPA) produces the symptoms of sore throat, fever, neck stiffness, and stridor. RPA occurs less commonly today than in the past because of the widespread use of antibiotics for suppurative upper respiratory infections. The incidence of RPA in the United States is rising, however. Once almost exclusively a disease of children, RPA is observed with increasing frequency in adults. It poses a diagnostic challenge for the emergency physician because of its infrequent occurrence and variable presentation.
An intracranial hematoma occurs when a blood vessel ruptures within your brain or between your skull and your brain. The collection of blood (hematoma) compresses your brain tissue. An intracranial hematoma may occur because the fluid that surrounds your brain can't absorb the force of a sudden blow or a quick stop. Then your brain may slide forcefully against the inner wall of your skull and become bruised. Although some head injuries — such as one that causes only a brief lapse of consciousness (concussion) — can be minor, an intracranial hematoma is potentially life-threatening and often requires immediate treatment. An intracranial hematoma often, but not always, requires surgery to remove the blood.
Coronary artery bypass graft surgery (CABG) is a procedure used to treat coronary artery disease. Coronary artery disease (CAD) is the narrowing of the coronary arteries – the blood vessels that supply oxygen and nutrients to the heart muscle. CAD is caused by a build-up of fatty material within the walls of the arteries. This build-up narrows the inside of the arteries, limiting the supply of oxygen-rich blood to the heart muscle. One way to treat the blocked or narrowed arteries is to bypass the blocked portion of the coronary artery with a piece of a healthy blood vessel from elsewhere in the body. Blood vessels, or grafts, used for the bypass procedure may be pieces of a vein from the legs or an artery in the chest. An artery from the wrist may also be used. One end of the graft is attached above the blockage and the other end is attached below the blockage. Blood is routed around, or bypasses, the blockage by going through the new graft to reach the heart muscle. This is called coronary artery bypass surgery. Traditionally, to bypass the blocked coronary artery, a large incision is made in the chest and the heart is temporarily stopped so that the surgeon can perform the delicate procedure. To open the chest, the breastbone (sternum) is cut in half and spread apart. Once the heart is exposed, tubes are inserted into the heart so that the blood can be pumped through the body by a cardiopulmonary bypass machine (heart-lung machine). The bypass machine is necessary to pump blood while the heart is stopped and kept still in order for the surgeon to perform the bypass operation. While the traditional "open heart" procedure is still commonly done and often preferred in many situations, less invasive techniques have been developed to bypass blocked coronary arteries. "Off-pump" procedures, in which the heart does not have to be stopped, were developed in the 1990's. Other minimally invasive procedures, such as keyhole surgery (performed through very small incisions) and robotic procedures (performed with the aid of a moving mechanical device), may be used.
Hypertensive emergencies encompass a spectrum of clinical presentations in which uncontrolled blood pressures (BPs) lead to progressive or impending end-organ dysfunction. In these conditions, the BP should be lowered aggressively over minutes to hours. Neurologic end-organ damage due to uncontrolled BP may include hypertensive encephalopathy, cerebral vascular accident/cerebral infarction, subarachnoid hemorrhage, and/or intracranial hemorrhage.[1] Cardiovascular end-organ damage may include myocardial ischemia/infarction, acute left ventricular dysfunction, acute pulmonary edema, and/or aortic dissection. Other organ systems may also be affected by uncontrolled hypertension, which may lead to acute renal failure/insufficiency, retinopathy, eclampsia, or microangiopathic hemolytic anemia.[1] With the advent of antihypertensives, the incidence of hypertensive emergencies has declined from 7% to approximately 1% of patients with hypertension.[2] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment
arteriovenous hemodialysis access has been the "gold standard" for patients needing hemodialysis for the past 30 years. Despite the reported advantages of autologous access, the availability of prosthetic graft material, coupled with the challenging dialysis candidate, has led to a trend of primary prosthetic graft dialysis access in the 1980s and 1990s. In recognition of this unfortunate trend, the National Kidney Foundation Dialysis Outcomes Quality Initiative (DOQI) used evidence from published studies and summary articles to generate clinical practice guidelines, emphasizing a shift back to autologous arteriovenous fistula (AVF) as the key to long-term successful hemodialysis.[1,2] These initial guidelines proposed a goal of 50% autologous AVF as the initial access, with a 40% prevalence of autologous access for a given practice or unit.
Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood's chemical makeup may get out of balance. Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly over a few hours or a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care. Acute kidney failure can be fatal and requires intensive treatment. However, acute kidney failure may be reversible. If you're otherwise in good health, you may recover normal or nearly normal kidney function.
Cardiac arrest is the abrupt loss of heart function in a person who may or may not have diagnosed heart disease. The time and mode of death are unexpected. It occurs instantly or shortly after symptoms appear. Each year, more than 350,000 emergency medical services-assessed out-of-hospital cardiac arrests occur in the United States
Infant jaundice is a yellow discoloration in a newborn baby's skin and eyes. Infant jaundice occurs because the baby's blood contains an excess of bilirubin (bil-ih-ROO-bin), a yellow-colored pigment of red blood cells. Infant jaundice is a common condition, particularly in babies born before 38 weeks gestation (preterm babies) and some breast-fed babies. Infant jaundice usually occurs because a baby's liver isn't mature enough to get rid of bilirubin in the bloodstream. In some cases, an underlying disease may cause jaundice. Treatment of infant jaundice often isn't necessary, and most cases that need treatment respond well to noninvasive therapy. Although complications are rare, a high bilirubin level associated with severe infant jaundice or inadequately treated jaundice may cause brain damage.

A heart attack occurs when the flow of blood to the heart is blocked, most often by a build-up of fat, cholesterol and other substances, which form a plaque in the arteries that feed the heart (coronary arteries). The interrupted blood flow can damage or destroy part of the heart muscle. A heart attack, also called a myocardial infarction, can be fatal, but treatment has improved dramatically over the years. It's crucial to call 911 or emergency medical help if you think you might be having a heart attack
Tobacco use is the most common preventable cause of death. About half of the people who don't quit smoking will die of smoking-related problems. Quitting smoking is important for your health. Soon after you quit, your circulation begins to improve, and your blood pressure starts to return to normal. Your sense of smell and taste return, and it's easier for you to breathe. In the long term, giving up tobacco can help you live longer. Your risk of getting cancer decreases with each year you stay smoke-free. Quitting is not easy. You may have short-term affects such as weight gain, irritability, and anxiety. Some people try several times before they succeed. There are many ways to quit smoking. Some people stop "cold turkey." Others benefit from step-by-step manuals, counseling, or medicines or products that help reduce nicotine addiction. Some people think that switching to e-cigarettes can help you quit smoking, but that has not been proven. Your health care provider can help you find the best way for you to quit.
Thoracentesis (THOR-ah-sen-TE-sis) is a procedure to remove excess fluid in the space between the lungs and the chest wall. This space is called the pleural space. Normally, the pleural space is filled with a small amount of fluid—about 4 teaspoons full.

Cardiogenic shock is a condition in which your heart suddenly can't pump enough blood to meet your body's needs. The condition is most often caused by a severe heart attack. Cardiogenic shock is rare, but it's often fatal if not treated immediately. If treated immediately, about half the people who develop the condition survive.
Invasive intracranial pressure monitoring. The most common surgically placed monitors for ICP measurement are intraventricular catheters (external ventricular drain [EVD] or a ventriculostomy drain) and fiberoptic ICP monitors implanted into the parenchyma of the brain.
Basic ECG Interpretation Our ECG Interpretation Training and Reference Guides provide basic lessons for ECG analysis as well as a quick reference guide for over 40 types of ECG tracings. The arrhythmia drills and quizzes allow you to practice ECG interpretation. What is ECG Interpretation? An electrocardiogram or ECG, records electrical activity in the heart. An ECG machine records these electrical signals across multiple heart beats and produces an ECG strip that is interpreted by a healthcare professional. How Electrocardiograms Work - ECG Strips To briefly summarize the components of a normal ECG tracings, it consist of waveform components which indicate electrical events during one heart beat. These waveforms are labeled P, Q, R, S, T and U. P wave is the first short upward movement of the ECG tracing. It indicates that the atria are contracting, pumping blood into the ventricles. The QRS complex, normally beginning with a downward deflection, Q; a larger upwards deflection, a peak (R); and then a downwards S wave. The QRS complex represents ventricular depolarization and contraction. The PR interval indicates the transit time for the electrical signal to travel from the sinus node to the ventricles. T wave is normally a modest upwards waveform representing ventricular repolarization.
