Pericardial Effusion
A pericardial effusion is an abnormal accumulation of fluid in the pericardial cavity. The pericardium is a two-part membrane surrounding the heart: the outer fibrous connective membrane and an inner two-layered serous membrane. The two layers of the serous membrane enclose the pericardial cavity (the potential space) between them.Phelan, D., Collier, P., Grimm, R. Pericardial Disease'. Cleveland Clinic. July 2015. Retrieved Nov 2020. This pericardial space contains a small amount of pericardial fluid. The fluid is normally 15-50 mL in volume. The pericardium, specifically the pericardial fluid provides lubrication, maintains the anatomic position of the heart in the chest, and also serves as a barrier to protect the heart from infection and inflammation in adjacent tissues and organs.Vogiatzidis, Konstantinos et al.Physiology of pericardial fluid production and drainage" ''Frontiers in physiology'' vol. 6 62. 18 Mar. 2015, doi:10.3389/fphys.2015.00062 By definition, a pericardial e ...

Transthoracic Echocardiogram
A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound. In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart. It is used as a non-invasive assessment of the overall health of the heart, including a patient's heart valves and degree of heart muscle contraction (an indicator of the ejection fraction). The images are displayed on a monitor for real-time viewing and then recorded. Often abbreviated "TTE", it can be easily confused with transesophageal echocardiography which is abbreviated "TEE". Pronunciation of "TTE" and "TEE" are similar, and full use of "transthoracic" or "transesophageal" can minimize any verbal miscommunication. Details A TTE is a clinical tool to evaluate the structure and function of the heart. All four chambers and all four valves can be assessed by TTE, but the quality an ...

Dysphagia
Dysphagia is difficulty in swallowing. Although classified under "symptoms and signs" in ICD-10, in some contexts it is classified as a disease#Terminology, condition in its own right. It may be a sensation that suggests difficulty in the passage of solids or liquids from the mouth to the stomach, a lack of Pharynx, pharyngeal sensation or various other inadequacies of the swallowing mechanism. Dysphagia is distinguished from other symptoms including odynophagia, which is defined as painful swallowing, and Globus Pharyngis, globus, which is the sensation of a lump in the throat. A person can have dysphagia without odynophagia (dysfunction without pain), odynophagia without dysphagia (pain without dysfunction) or both together. A psychogenic disease, psychogenic dysphagia is known as phagophobia. Classification Dysphagia is classified into the following major types: # Oropharyngeal dysphagia # Esophageal dysphagia, Esophageal and obstructive dysphagia # Neuromuscular symptom comp ...

Primary Tumor
A primary tumor is a tumor growing at the anatomical site where tumor progression began and proceeded to yield a cancerous mass. Most cancers develop at their primary site but then go on to metastasize or spread to other parts of the body. These further tumors are secondary tumors. Most cancers continue to be called after their primary site, as in breast cancer or lung cancer for example, even after they have spread to other parts of the body. Cancer of unknown primary origin Cancer of unknown primary origin (CUP) is a cancer that is determined to be at the metastatic stage at the time of diagnosis, but a primary tumor cannot be identified. A diagnosis of CUP requires a clinical picture consistent with metastatic di ... is cancer in which secondary tumors are found but the original primary site cannot be decided.

Malignancy
Malignancy () is the tendency of a medical condition to become progressively worse. Malignancy is most familiar as a characterization of cancer. A ''malignant'' tumor contrasts with a non-cancerous ''benign'' tumor in that a malignancy is not self-limited in its growth, is capable of invading into adjacent tissues, and may be capable of spreading to distant tissues. A benign tumor has none of those properties. Malignancy in cancers is characterized by anaplasia, invasiveness, and metastasis. Malignant tumors are also characterized by genome instability, so that cancers, as assessed by whole genome sequencing, frequently have between 10,000 and 100,000 mutations in their entire genomes. Cancers usually show tumour heterogeneity, containing multiple subclones. They also frequently have reduced expression of DNA repair enzymes due to epigenetic methylation of DNA repair genes or altered microRNAs that control DNA repair gene expression. Tumours can be detected through the visual ...

Minoxidil
Minoxidil, sold under the brand name Rogaine among others, is a medication used for the treatment of high blood pressure and pattern hair loss. It is an antihypertensive vasodilator. It is available as a generic medication by prescription in oral tablet form and over the counter as a topical liquid or foam. Medical uses Minoxidil, when used for hypertension, is generally reserved for use in severe hypertension patients who can not respond to at least two agents and a diuretic. Minoxidil is also generally administered with a loop diuretic to prevent sodium and potassium retention. It may also cause a reflex tachycardia and thus is prescribed with a beta blocker. Minoxidil, applied topically, is widely used for the treatment of hair loss. It is effective in helping promote hair growth in people with androgenic alopecia regardless of sex. Minoxidil must be used indefinitely for continued support of existing hair follicles and the maintenance of any experienced hair regrowth. Lo ...

Rheumatoid Arthritis
Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects joints. It typically results in warm, swollen, and painful joints. Pain and stiffness often worsen following rest. Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body. The disease may also affect other parts of the body, including skin, eyes, lungs, heart, nerves and blood. This may result in a low red blood cell count, inflammation around the lungs, and inflammation around the heart. Fever and low energy may also be present. Often, symptoms come on gradually over weeks to months. While the cause of rheumatoid arthritis is not clear, it is believed to involve a combination of genetic and environmental factors. The underlying mechanism involves the body's immune system attacking the joints. This results in inflammation and thickening of the joint capsule. It also affects the underlying bone and cartilage. The diagnosis is made mos ...

Lupus
Lupus, technically known as systemic lupus erythematosus (SLE), is an autoimmune disease in which the body's immune system mistakenly attacks healthy tissue in many parts of the body. Symptoms vary among people and may be mild to severe. Common symptoms include painful and swollen joints, fever, chest pain, hair loss, mouth ulcers, swollen lymph nodes, feeling tired, and a red rash which is most commonly on the face. Often there are periods of illness, called flares, and periods of remission during which there are few symptoms. The cause of SLE is not clear. It is thought to involve a mixture of genetics combined with environmental factors. Among identical twins, if one is affected there is a 24% chance the other one will also develop the disease. Female sex hormones, sunlight, smoking, vitamin D deficiency, and certain infections are also believed to increase a person's risk. The mechanism involves an immune response by autoantibodies against a person's own tissues. T ...

Pericarditis
Pericarditis is inflammation of the pericardium, the fibrous sac surrounding the heart. Symptoms typically include sudden onset of sharp chest pain, which may also be felt in the shoulders, neck, or back. The pain is typically less severe when sitting up and more severe when lying down or breathing deeply. Other symptoms of pericarditis can include fever, weakness, palpitations, and shortness of breath. The onset of symptoms can occasionally be gradual rather than sudden. The cause of pericarditis often remains unknown but is believed to be most often due to a viral infection. Other causes include bacterial infections such as tuberculosis, uremic pericarditis, heart attack, cancer, autoimmune disorders, and chest trauma. Diagnosis is based on the presence of chest pain, a pericardial rub, specific electrocardiogram (ECG) changes, and fluid around the heart. A heart attack may produce similar symptoms to pericarditis. Treatment in most cases is with NSAIDs and possibly the ant ...

Dressler's Syndrome
Dressler syndrome is a secondary form of pericarditis that occurs in the setting of injury to the heart or the pericardium (the outer lining of the heart). It consists of fever, pleuritic pain, pericarditis and/or a pericardial effusion. Dressler syndrome is also known as postmyocardial infarction syndrome and the term is sometimes used to refer to post-pericardiotomy pericarditis. It was first characterized by William Dressler at Maimonides Medical Center in 1956. It should not be confused with the Dressler's syndrome of haemoglobinuria named for Lucas Dressler, who characterized it in 1854. Presentation Dressler syndrome was historically a phenomenon complicating about 7% of myocardial infarctions, but in the era of percutaneous coronary intervention, it is very uncommon. The disease consists of a persistent low-grade fever, chest pain (usually pleuritic), pericarditis (usually evidenced by a pericardial friction rub, chest pain worsening when recumbent, and diffuse ST elev ...

Postpericardiotomy Syndrome
Postpericardiotomy syndrome (PPS) is a medical syndrome referring to an immune phenomenon that occurs days to months (usually 1–6 weeks) after surgical incision of the pericardium (membranes encapsulating the human heart). PPS can also be caused after a trauma, a puncture of the cardiac or pleural structures (such as a bullet or stab wound), after percutaneous coronary intervention (such as stent placement after a myocardial infarction or heart attack), or due to pacemaker or pacemaker wire placement. Signs and symptoms The typical signs of post-pericardiotomy syndrome include fever, pleuritis (with possible pleural effusion), pericarditis (with possible pericardial effusion), occasional but rare pulmonary infiltrates, and fatigue. Cough, pleuritic or retrosternal chest pain, joint pain and decreased oxygen saturation can also be seen in some cases. Other signs include arthritis, together with petechiae on the skin and palate. Complications Complications include pericarditis, p ...

Heart Surgery
Cardiac surgery, or cardiovascular surgery, is surgery on the heart or great vessels performed by cardiac surgeons. It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, and atherosclerosis. It also includes heart transplantation. History 19th century The earliest operations on the pericardium (the sac that surrounds the heart) took place in the 19th century and were performed by Francisco Romero (1801) in the city of Almería (Spain), Dominique Jean Larrey (1810), Henry Dalton (1891), and Daniel Hale Williams (1893). The first surgery on the heart itself was performed by Axel Cappelen on 4 September 1895 at Rikshospitalet in Kristiania, now Oslo. Cappelen ligated a bleeding coronary artery in a 24-year-old man who had been stabbed in the left axilla and was in deep sho ...

Trichinosis
Trichinosis, also known as trichinellosis, is a parasitic disease caused by roundworms of the ''Trichinella'' type. During the initial infection, invasion of the intestines can result in diarrhea, abdominal pain, and vomiting. Migration of larvae to muscle, which occurs about a week after being infected, can cause swelling of the face, inflammation of the whites of the eyes, fever, muscle pains, and a rash. Minor infection may be without symptoms. Complications may include inflammation of heart muscle, central nervous system involvement, and inflammation of the lungs. Trichinosis is mainly spread when undercooked meat containing ''Trichinella'' cysts is eaten. In North America this is most often bear, but infection can also occur from pork, boar, and dog meat. Several species of ''Trichinella'' can cause disease, with ''T. spiralis'' being the most common. After the infected meat has been eaten, the larvae are released from their cysts in the stomach. They then invade the ...
