Myocardial infarction (MI), commonly known as a heart attack, is defined pathologically as the irreversible death of myocardial cells caused by ischemia. Clinically, MI is a syndrome that can be recognized by a set of symptoms, chest pain being the hallmark of these symptoms in most cases, supported by biochemical laboratory changes, electrocardiographic (ECG) changes, or findings on imaging modalities able to detect myocardial injury and necrosis. According to the third universal definition of MI, implemented by a joint task force from the European Society of Cardiology (ESC), American College of Cardiology (ACC) Foundation, American Heart Association (AHA), and the World Heart Federation (WHF), MI is diagnosed when either of the following two criteria are met

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.

You might not notice signs or symptoms of Hashimoto's disease at first, or you may notice a swelling at the front of your throat (goiter). Hashimoto's disease typically progresses slowly over years and causes chronic thyroid damage, leading to a drop in thyroid hormone levels in your blood. The signs and symptoms are mainly those of an underactive thyroid gland (hypothyroidism). Signs and symptoms of hypothyroidism include: Fatigue and sluggishness Increased sensitivity to cold Constipation Pale, dry skin A puffy face Hoarse voice Unexplained weight gain โ€” occurring infrequently and rarely exceeding 10 to 20 pounds, most of which is fluid Muscle aches, tenderness and stiffness, especially in your shoulders and hips Pain and stiffness in your joints and swelling in your knees or the small joints in your hands and feet Muscle weakness, especially in your lower extremities Excessive or prolonged menstrual bleeding (menorrhagia) Depression

Wahrscheinlich wirst du dich als Paleo-Anhรคnger schon einmal gefragt haben, warum die Steinzeiternรคhrung Getreide meidet wie die Pest. Gut, die Begrรผndung, dass Menschen vor Tausenden von Jahren ebenfalls kein Getreide hatten, ist ja schรถn. Aber das kann ja nicht alles sein. Ist es auch nicht. Wie immer liegt der Teufel im Detail. Hauptverantwortlich fรผr die groรŸe โ€žAngstโ€œ vor Getreideprodukten sind vor allem Gluten, sogenannte Anti-Nรคhrstoffe. Bereits dieser Name ist angsteinflรถรŸend. Und das durchaus zu Recht. Denn Gluten besitzen nur wenige positive, dafรผr jedoch umso mehr negative Eigenschaften, die sich lรคngerfristig schlecht auf deine Gesundheit auswirken kรถnnen. Was ist Gluten und welche Lebensmittel enthalten Gluten? Gluten ist ein EiweiรŸ mit besonders starken Klebeeigenschaften. Dies ist auch der Grund, weswegen beispielsweise Brotteig so gut zusammenklebt. Gluten findet sich hauptsรคchlich in Getreide, beispielsweise ein Roggen oder Gerste, Dinkel oder Weizen und Hafer. Hieraus ergibt sich zwangslรคufig, dass auch viele Lebensmittel des tรคglichen Lebens jede Menge Gluten enthalten. Hierzu gehรถren nicht nur Schokolade oder Bier, Reis oder Nudeln, sondern auch Pommes oder Milcherzeugnisse. Auch in den meisten Fertiggerichten ist Gluten vorzufinden.

This video: Pericarditis is swelling and irritation of the pericardium, the thin sac-like membrane surrounding your heart. Pericarditis often causes chest pain and sometimes other symptoms. The sharp chest pain associated with pericarditis occurs when the irritated layers of the pericardium rub against each other. Pericarditis usually begins suddenly but doesn't last long (acute). When symptoms develop more gradually or persist, pericarditis is considered chronic. Most cases are mild and usually improve on their own. Treatment for more-severe cases may include medications and, rarely, surgery. Early diagnosis and treatment may help to reduce the risk of long-term complications from pericarditis.

Pulmonary embolism symptoms can vary greatly, depending on how much of your lung is involved, the size of the clots, and whether you have underlying lung or heart disease. Common signs and symptoms include: Shortness of breath. This symptom typically appears suddenly and always gets worse with exertion. Chest pain. You may feel like you're having a heart attack. The pain may become worse when you breathe deeply (pleurisy), cough, eat, bend or stoop. The pain will get worse with exertion but won't go away when you rest. Cough. The cough may produce bloody or blood-streaked sputum. Other signs and symptoms that can occur with pulmonary embolism include: Leg pain or swelling, or both, usually in the calf Clammy or discolored skin (cyanosis) Fever Excessive sweating Rapid or irregular heartbeat Lightheadedness or dizziness

The most common symptoms noticed by people with haemochromatosis (inherited iron overload disorder) are โ€ข Fatigue, weakness and lethargy โ€ข Joint pains leading to osteoarthritis * Other symptoms include: โ€ข Abdominal pain โ€ข Diabetes โ€ข Liver disorders; enlarged liver, cirrhosis โ€ข Sexual disorders; loss of sex drive in both male and female, impotence in men, absent or scanty menstrual periods and early menopause in women โ€ข Decrease in body hair โ€ข Discolouration or bronzing of the skin โ€ข Cardiomyopathy; disease of the heart muscle โ€ข Neurological/psychiatric disorders; impaired memory, mood swings, severe irritability, depression. These symptoms, if present, take time to develop. No two people are alike and symptoms will vary from person to person. Some people never develop any symptoms at all. All of the symptoms of haemochromatosis can also be caused by other medical conditions or even just the stresses of modern life. They develop slowly and people often do not notice what is happening for a long time. This can make haemochromatosis difficult to diagnose. Symptoms are caused by high levels of iron stored in the body. One indicator of the level of iron stored is serum ferritin. If iron stores are high the serum ferritin level will be high, but serum ferritin levels can also be raised by other factors. The normal range is 20 โ€“ 300 micrograms per litre (ยตg/L) for men and 10 โ€“ 200 ยตg/L for women. There is strong medical evidence of a potential for significant organ damage when iron stores cause serum ferritin levels above 1,000 ยตg/L. However some people seem to experience symptoms with levels between 300 and 1,000 ยตg/L. Higher levels are more likely to be associated with more severe symptoms. If haemochromatosis is diagnosed and treated before serious iron overload and significant damage occurs, most symptoms will decrease or disappear. However there is evidence that treatment may not alleviate arthritis symptoms.

Myocardial rupture occurs in the setting of acute myocardial infarction (AMI), blunt and penetrating cardiac trauma, primary cardiac infection, primary and secondary cardiac tumors, infiltrative diseases of the heart, and aortic dissection. Myocardial rupture (or perforation) may also occur iatrogenically during percutaneous cardiac procedures (including device implantation) or open heart surgery (particularly valve replacement). Recently, myocardial rupture has been reported in the setting of stress cardiomyopathy (Takotsubo or regional ventricular ballooning syndrome). The clinical presentation of myocardial rupture depends on the mechanism and site of injury and the hemodynamic effects of the rupture. Mortality is extremely high unless early diagnosis is made and urgent surgical intervention is provided.

Indications for intervention in patients with a renal artery aneurysm (RAA) include the following [20, 8, 13, 14] : Rupture Symptomatic RAA - Hypertension (from associated renal artery stenosis, refractory to medical management), pain, renal ischemia or infarction secondary to embolization from the aneurysm sac RAAs in females who are pregnant or are contemplating pregnancy Diameter greater than 2 cm Enlarging RAA RAA associated with acute dissection Currently, there is no consensus regarding the size at which an RAA should be repaired in an asymptomatic patient. Experts have recommended RAA repair at diameters ranging from 1.5 to 3 cm, [8] though most suggest 2 cm. Some reports have even suggest that larger asymptomatic saccular aneurysms may be managed expectantly. Note that aneurysm rupture at a diameter of 1.5 cm has been reported. Complete calcification of the wall of the aneurysm sac manifests in about 40% of patients. This was once believed to confer protection against rupture [21] ; however, this belief has since been questioned. [30] Asymptomatic, small (<2 cm in diameter) RAAs do not usually require treatment. One notable exception is an RAA in a woman who is pregnant or contemplating pregnancy. In view of the increased risk of rupture in such cases, even small asymptomatic aneurysms should be repaired in this population. For diagnosis and preinterventional planning, gadolinium-enhanced magnetic resonance angiography (MRA) and computed tomography (CT) angiography (CTA) with three-dimensional (3D) reconstruction have essentially replaced conventional arteriography. Regular follow-up examination with ultrasonography (US) or CT) is recommended in patients who are treated expectantly. Spontaneous cure by thrombosis of small aneurysms has been described. Further refinements in endovascular techniques may allow more RAAs to be treated in this manner. So far, excellent short- and intermediate-term results have been described in the literature [40] ; however, there remains a need for further long-term outcome data.

Diabetic retinopathy (die-uh-BET-ik ret-ih-NOP-uh-thee) is a diabetes complication that affects eyes. It's caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). At first, diabetic retinopathy may cause no symptoms or only mild vision problems. Eventually, it can cause blindness. The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye complication.

Osteomyelitis is an infection in a bone. Infections can reach a bone by traveling through the bloodstream or spreading from nearby tissue. Infections can also begin in the bone itself if an injury exposes the bone to germs. In children, osteomyelitis most commonly affects the long bones of the legs and upper arms. Adults are more likely to develop osteomyelitis in the bones that make up the spine (vertebrae). People who have diabetes may develop osteomyelitis in their feet if they have foot ulcers. Once considered an incurable condition, osteomyelitis can be successfully treated today. Most people require surgery to remove parts of the bone that have died โ€” followed by strong antibiotics, often delivered intravenously, typically for at least four to six weeks.

Cells may have slender extensions of the cell membrane to form cilia or the smaller extensions called microvilli. The microscopic microvilli effectively increase the surface area of the cell and are useful for absorption and secretion functions. A dramatic example is the human small intestine. The tissue has small fingerlike extensions called villi which are collections of cells, and those cells have many microvilli to even further increase the available surface area for the digestion process. According to Audesirk & Audesirk, this can give an effective surface area of about 250 square meters for absorption.
