Pulmonary edema is a condition characterized by an accumulation of excess fluid in the lungs. This fluid can collect in the many air sacs in the lungs, making it difficult to breathe. Pulmonary edema is a serious condition that requires prompt medical attention to prevent complications and ensure proper treatment.
Pulmonary embolism is a medical emergency that occurs when a blood clot forms in the deep veins of the body and travels to the lungs, blocking blood flow and preventing oxygen from reaching the body's vital organs. This condition can be life-threatening if left untreated, but prompt treatment can greatly reduce the risk of death.
Pulmonary fibrosis is a chronic and progressive lung disease that occurs when lung tissue becomes damaged and scarred. This scarring leads to the formation of thickened, stiff tissue that makes it difficult for the lungs to function properly. The disease worsens over time, with some people experiencing a stable course while others may experience a more rapid decline in lung function.
Pulmonary hypertension is a type of high blood pressure that affects the arteries in the lungs and the right side of the heart. It is a serious condition that requires immediate medical attention. In this article, we will discuss the causes, symptoms, diagnosis, treatment options, and prevention strategies for pulmonary hypertension.
Pulmonary valve disease is a condition that affects the valve between the heart's lower right chamber and the pulmonary artery. The pulmonary valve is responsible for regulating blood flow from the heart to the lungs. In pulmonary valve disease, the valve doesn't work properly, which can lead to changes in blood flow and potentially life-threatening complications.
Pyloric stenosis is a rare condition in infants that affects the passage of food from the stomach to the small intestine. It is characterized by the thickening and enlargement of the muscular valve between the stomach and small intestine, known as the pylorus valve. This blockage can lead to severe symptoms, including forceful vomiting, dehydration, and weight loss.
Pyoderma gangrenosum is a rare and chronic condition that causes large, painful sores (ulcers) to develop on the skin, most often on the legs. The exact causes of pyoderma gangrenosum are unknown, but it appears to be a disorder of the immune system. People who have certain underlying conditions, such as inflammatory bowel disease or arthritis, are at higher risk of developing pyoderma gangrenosum.
Rabies is a deadly viral disease that affects the central nervous system of mammals, including humans. The virus is usually transmitted through the saliva of infected animals, typically through a bite. Rabies is a serious public health concern worldwide, with an estimated 59,000 deaths occurring each year. In the United States, bats are the most common carriers of rabies, followed by coyotes, foxes, raccoons, and skunks. In developing countries, stray dogs are the primary source of transmission.
Radiation enteritis is a common side effect of radiation therapy that occurs when the intestines are exposed to high levels of radiation. This condition can cause a range of symptoms, including diarrhea, nausea, vomiting, and stomach cramps. Radiation enteritis is most common in people receiving radiation therapy for cancer in the abdomen and pelvic areas.
Radiation sickness is a serious and potentially fatal condition caused by the exposure of the body to a large dose of radiation over a short period of time. This condition is also known as acute radiation syndrome (ARS) or radiation poisoning. Radiation sickness is not caused by common medical imaging tests that use low-dose radiation, such as X-rays, CT scans, and nuclear medicine scans.
Ramsay Hunt syndrome is a rare and complex condition that occurs when the virus that causes chickenpox, also known as varicella-zoster, reactivates and affects the facial nerve near one of your ears. This condition is also known as herpes zoster oticus. The symptoms of Ramsay Hunt syndrome can include a painful shingles rash, facial paralysis, and hearing loss in the affected ear.
Raynaud's disease is a condition that affects the blood vessels in the body, causing them to narrow or constrict in response to cold temperatures or stress. This narrowing of the blood vessels can lead to a decrease in blood flow to the affected areas, causing numbness and coldness in the fingers and toes.
Reactive arthritis is a condition that causes joint pain and swelling in response to an infection in another part of the body. This condition is also known as Reiter's syndrome. It is not a common condition and usually affects the knees, ankles, and feet. Inflammation can also affect the eyes, skin, and the tube that carries urine out of the body (urethra).
Reactive attachment disorder is a rare but serious condition that affects infants and young children. It is characterized by a lack of healthy attachment with caregivers, which can lead to social and emotional difficulties later in life. Reactive attachment disorder may develop if the child's basic needs for comfort, affection, and nurturing are not met.
Rectal cancer is a type of cancer that starts in the rectum, the last several inches of the large intestine. It is a type of colorectal cancer, which also includes cancer in the colon. Rectal cancer is a serious condition that requires prompt medical attention. In this article, we will explore the causes, symptoms, prevention strategies, and treatment options for rectal cancer.
