KembaraXtra - Medical Terms - acute respiratory failure (ARF) Acute respiratory failure (ARF) is a serious condition in which the body is unable to properly exchange oxygen and carbon dioxide in the lungs. This failure primarily involves a breakdown in the process of gaseous exchange rather than a mechanical problem with breathing movements. As a result, oxygen levels in the blood may fall dangerously low, or carbon dioxide levels may rise, leading to life-threatening complications.
A classic example of ARF is adult respiratory distress syndrome, but the condition may also arise from dysfunction in other parts of the respiratory system, including the brain’s respiratory control centre and its neural pathways. ARF requires urgent medical attention and often involves supportive care such as oxygen therapy or mechanical ventilation to restore adequate gas exchange and maintain life.

KembaraXtra - Medical Terms - acute generalized exanthematous pustulosis
Acute generalized exanthematous pustulosis, sometimes called toxic pustuloderma, is a skin reaction most often caused by medications. It is characterized by the rapid appearance of numerous small sterile pustules on inflamed areas of the skin. These pustules may be subtle and easily overlooked during examination.
The condition is frequently associated with certain drugs, particularly penicillin antibiotics. When diagnosing this disorder, doctors must distinguish it from other skin conditions such as pustular psoriasis. Although it can appear dramatic, the reaction usually resolves after the responsible medication is discontinued and appropriate medical care is provided.

KembaraXtra - Medical Terms - acute fatty liver of pregnancy Acute fatty liver of pregnancy is a rare but potentially life-threatening complication that occurs during pregnancy, most commonly in the third trimester. It is characterized by the accumulation of fat within liver cells, which interferes with normal liver function.
Symptoms often include nausea, vomiting, general malaise, and abdominal pain. Laboratory tests typically reveal abnormal liver function, and the condition may occur together with complications such as pre-eclampsia or HELLP syndrome. Serious complications including hepatic encephalopathy, disseminated intravascular coagulation, and kidney failure may develop. Management requires urgent medical care and often involves a multidisciplinary team working in an intensive care setting.

KembaraXtra - Medical Terms - acute coronary syndrome Acute coronary syndrome is a medical term used to describe a group of conditions resulting from reduced blood flow to the heart muscle. It includes unstable angina, non-ST elevation myocardial infarction (NSTEMI), and ST-elevation myocardial infarction (STEMI). These conditions represent different degrees of severity within the same disease process.
The underlying cause is usually coronary artery disease, in which plaques within the coronary arteries reduce or block blood flow to the heart. Acute coronary syndrome requires urgent medical evaluation because the reduced oxygen supply can damage the heart muscle. Early treatment is essential to restore blood flow and minimize complications.

KembaraXtra - Medical Terms - acute abdomen
Acute abdomen refers to the sudden onset of severe abdominal pain and other symptoms caused by an underlying disease or injury affecting the abdominal organs. This condition represents a medical emergency because it often indicates serious internal problems that require immediate diagnosis and treatment.
Common causes include perforation of a peptic ulcer, acute appendicitis, inflammation of diverticula in the colon, or rupture of internal organs such as the liver or spleen following trauma. Because these conditions can deteriorate rapidly, prompt medical evaluation and often urgent surgical treatment are necessary to prevent life-threatening complications.

KembaraXtra - Medical Terms - acute
The term acute is used in medicine to describe a condition that develops rapidly and is often severe but typically lasts for a relatively short duration. Acute diseases usually begin suddenly and produce noticeable symptoms over a short period of time.
In another context, the word acute may also describe the intensity of a symptom rather than its duration. For example, acute pain refers to severe pain that may arise suddenly due to injury or illness. The term is commonly contrasted with chronic, which describes conditions that develop slowly and persist for long periods.

KembaraXtra - Medical Terms - acupuncture
Acupuncture is a complementary therapy that involves inserting very fine sterile needles into specific points on the body. This treatment originated in traditional Eastern medicine and is based on the concept that the body contains pathways called meridians through which vital energy, known as qi, flows.
According to this theory, illness may result from disruptions in the flow of qi, and acupuncture aims to restore balance by stimulating particular points along these pathways. From a modern medical perspective, acupuncture may work by stimulating nerves and promoting the release of natural pain-relieving substances in the body, such as endorphins. It is commonly used to relieve symptoms associated with chronic pain and certain other physical and psychological conditions.

KembaraXtra - Medical Terms - actomyosin
Actomyosin is a protein complex formed by the interaction of two muscle proteins: actin and myosin. These proteins are the primary components responsible for muscle contraction. When muscle fibres contract, actin and myosin filaments slide past one another in a coordinated manner.
The formation of the actomyosin complex is a key step in this process. Through repeated cycles of attachment and movement between the two proteins, the muscle fibre shortens and produces force. This mechanism underlies many types of bodily movement, including voluntary movements controlled by skeletal muscles and certain involuntary muscular activities.

KembaraXtra - Medical Terms - activities of daily living (ADLs) Activities of daily living, commonly abbreviated as ADLs, refer to the routine tasks that individuals perform every day to maintain personal independence and basic functioning. These activities are often used in healthcare assessments to evaluate a person’s ability to live independently and manage self-care.
Basic ADLs include essential self-care tasks such as bathing, dressing, eating, grooming, using the toilet, and moving from place to place. Instrumental ADLs involve more complex activities necessary for independent living, including cooking, shopping, managing finances, taking medications, and performing housework. Difficulty performing ADLs is frequently used as a practical indicator of disability, particularly among elderly individuals or those with chronic illnesses.

KembaraXtra - Medical Terms - activin
Activin is a protein complex involved in regulating the production of follicle-stimulating hormone (FSH) in the body. It is produced in several tissues and acts primarily on the pituitary gland to increase both the synthesis and secretion of FSH. This hormone plays a major role in reproductive processes, including the development of ovarian follicles in women.
Activin is closely related to another regulatory protein known as inhibin. While activin stimulates the production of FSH, inhibin acts in the opposite way by reducing its synthesis and release. The balance between activin and inhibin helps regulate the menstrual cycle and other aspects of reproductive hormone control.
