Ear irrigation is a routine procedure used to remove excess earwax, called cerumen, or foreign materials from the ear. The ear naturally secretes earwax to protect, lubricate, keep debris out, and regulate bacterial growth. Under normal conditions, the body keeps the amount of earwax in the ears .
Cholecystectomy means removal of the gallbladder. The most common reasons
your doctor might recommend a cholecystectomy are biliary colic, cholecystitis,
choledocolithiasis, or gallstone pancreatitis. Biliary colic, also known as symptomatic
cholelithiasis, is caused by gallstones, which are hardened deposits of bile. Gallstones are
common in the general population, and gallstones alone are not a reason for gallbladder
removal if they do not cause symptoms. However, sometimes gallstones can get caught at the
neck of the gallbladder, causing pain when the gallbladder contracts against them trying to
release its bile, especially after a fatty meal. With biliary colic, the pain typically resolves within
an hour or so. Occasionally, a stone or some other blockage may prevent the gallbladder from
emptying over a long period of time, causing an increase in pressure and trapped fluid within the
gallbladder. This can cause inflammation and infection of the gallbladder, which we call
cholecystitis. Choledocholithiasis is when there are one or more stones in the bile ducts, which
can cause back up of bile into the liver, and depending on the location of the stones, could
cause pancreatitis, which is inflammation of the pancreas. Other reasons for gallbladder
removal, though less common, are gallbladder polyps and cancer. All of these are reasons for
gallbladder removal.
Acute kidney injury is common entity in medical practice. The present definition is based on a serum creatinine rise of more 0.3 mg/dl in 48 hours or less, a 50% increase from the baseline over a period of 07 days or a urine output of less than 0.5 ml/kg/hour for more than 06 hours. The main causes of acute kidney injury may be classified into pre renal, intrinsic or post renal causes. Rapid diagnosis and prompt treatment is essential to prevent mortality or morbidity. This presentation discusses in detail the causes of all three mechanisms, pre-renal, post renal and intrinsic.
Angina is a term used for chest pain caused by reduced blood flow to the heart muscle. Angina (an-JIE-nuh or AN-juh-nuh) is a symptom of coronary artery disease. Angina is typically described as squeezing, pressure, heaviness, tightness or pain in your chest. Angina, also called angina pectoris, can be a recurring problem or a sudden, acute health concern. Angina is relatively common but can be hard to distinguish from other types of chest pain, such as the pain or discomfort of indigestion. If you have unexplained chest pain, seek medical attention right away.
Microscopic polyangiitis (MPA) is vasculitis of small vessels. It was initially considered as a microscopic form of polyarteritis nodosa (PAN). In 1990, the American College of Rheumatology developed classification criteria for several types of systemic vasculitis but did not distinguish between polyarteritis nodosa and microscopic polyarteritis nodosa. [1] In 1994, a group of experts held an international consensus conference in Chapel Hill, North Carolina, to attempt to redefine the classification of small vessel vasculitides. [2, 3]
The Zika virus, first identified in Uganda in 1947, is transmitted by the same type of mosquito that carries dengue fever, yellow fever, and chikungunya virus. A mosquito bites an infected person and then passes those viruses to other people it bites. Outbreaks did not occur outside of Africa until 2007, when it spread to the South Pacific.
Juvenile rheumatoid arthritis, also known as juvenile idiopathic arthritis, is the most common type of arthritis in children under the age of 17. Juvenile rheumatoid arthritis causes persistent joint pain, swelling and stiffness. Some children may experience symptoms for only a few months, while others have symptoms for the rest of their lives. Some types of juvenile rheumatoid arthritis can cause serious complications, such as growth problems and eye inflammation. Treatment of juvenile rheumatoid arthritis focuses on controlling pain, improving function and preventing joint damage.
The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body's tissues. With each heartbeat, blood is sent throughout our bodies, carrying oxygen and nutrients to all of our cells.
