GUILLAIN-BARRE SYNDROME OR INFECTIOUS POLYNEURITIS – Etiology, Pathophysiology, Signs and Symptoms, Diagnostic Evaluation and Management Guillain-Barre Syndrome (GBS) is a acute condition that involves progressive muscle weakness or paralysis. It is an autoimmune disorder in which the body’s immune system attacks its own nervous system, causing inflammation that damages the myelin sheath of the nerve. This damage (demyleinazation) slows or stops the conduction of impulses through the nerve. The impairment of nerve impulses to the muscles leads to symptoms that may include muscle weakness, paralysis, spasms, numbness, tingling or pin-and-needle sensations and tenderness. ETIOLOGY Camphylobacter jejuni infection: camphylobacter infection is also the most common risk factor for Guillain-Barre. It is often found in undercooked food, especially poultry. Influenza Cytomegalovirus Epstein-Barr virus infection Mycoplasma pneumonia HIV or AIDS PATHOPHYSIOLOGY A condition of symptoms characteriz...

Medical Knowledge 13 1. Rheumatoid arthritis (RA) is an autoimmune disease. Rheumatoid arthritis (RA) is indeed an autoimmune disease. Autoimmune diseases occur when the body's immune system, which is responsible for protecting the body against harmful substances like bacteria and viruses, mistakenly attacks its own healthy tissues. In the case of rheumatoid arthritis, the immune system primarily targets the joints, leading to inflammation, pain, and damage. In a person with RA, the immune system mistakenly identifies the lining of the joints, called the synovium, as a threat and launches an immune response. This immune response involves the release of various inflammatory substances, such as cytokines, which lead to chronic inflammation in the joints. Over time, this persistent inflammation can result in joint damage, deformity, and functional limitations. While the exact cause of rheumatoid arthritis is still unknown, it is believed to involve a combination of genetic and environ...

Child health nursing -Chapter:  Growth and Development  Topic: 1. Definition, principles, factors affecting growth & development, techniques of assessment, plotting of growth chart Growth refers to an increase in size and development refers to maturation of function. Starting from conception, growth and development is influenced by various factors both inside the uterus and external environment. Growth and development begin at conception and end at maturity. Definition of growth and development Growth is defined as an increase in size of an individual. This increase in size is due to increase in the number and diameter of the cells. Development denotes the functional maturity of the child. It is the mental maturation with acquisition of skills. Though growth and development are not the same, they are assessed simultaneously. They are unique characteristics of children and any problem in this process at any stage can result in deviation of growth and /or develop...

HARMONES and their functions Hormones are chemical messengers produced by various glands in the body that help regulate and coordinate the activities of different cells, tissues, and organs. They play a crucial role in maintaining overall homeostasis and controlling various physiological processes. Here are some important hormones and their functions: ▪️Insulin: Produced by the pancreas, insulin regulates the metabolism of carbohydrates, fats, and proteins. It helps lower blood glucose levels by facilitating the uptake of glucose into cells. ▪️Glucagon: Also produced by the pancreas, glucagon works in opposition to insulin. It raises blood glucose levels by stimulating the breakdown of glycogen into glucose in the liver, a process called glycogenolysis. ▪️Thyroid hormones (T3 and T4): Produced by the thyroid gland, these hormones regulate metabolism, growth, and development in the body. They influence the functioning of various organs and tissues, including the heart, brain, and m...

Medical Knowledge Part 12 1. Choose the correct route of oxygenated blood in the body starting from its oxygenation: A Lungs →Pulmonary artery →Left atrium →Left ventricle →Aorta →Tissues →Vena cava→Right atrium→ Right ventricle →Pulmonary vein→Lungs B Lungs →Pulmonary vein →Left atrium →Left ventricle →Aorta →Tissues →Pulmonary artery →Right atrium→ Right ventricle →Vena cava→Lungs C Lungs →Pulmonary vein →Left atrium →Left ventricle →Aorta →Tissues →Vena cava→Right atrium→ Right ventricle →Pulmonary artery→Lungs D Lungs →Pulmonary artery →Left atrium →Left ventricle →Aorta →Tissues →Vena cava→Right atrium→ Right ventricle →Pulmonary artery→Tissues 🔹Solution: The correct option is C Lungs →Pulmonary vein →Left atrium →Left ventricle →Aorta →Tissues →Vena cava→Right atrium→ Right ventricle →Pulmonary artery→Lungs The circulation of blood in human body is of two types: - Systemic circulation: The system of blood vessels that ensures the supply of oxygenated blood from the ...
