Introduction to Immunology..

-
Immunology is the branch of biology that deals with the study of the immune system, which is responsible for protecting the body against diseases and foreign substances. It involves the study of the cells, tissues, and organs involved in the immune response, as well as the mechanisms by which the immune system recognizes and eliminates pathogens. Immunology also explores the development and function of the immune system, as well as the disorders and diseases that can arise when the immune system malfunctions.

  Kwashiorkor and Marasmus (Protein-Energy Malnutrition Disorders) 1. Kwashiorkor Definition : Kwashiorkor is a severe form of protein deficiency that occurs mainly in children, even when calorie intake is adequate. Causes : Diet lacking in protein Often seen in developing countries during weaning (switching from breast milk to other foods) Infections that increase protein needs Symptoms : Swollen belly (edema) Thin muscles, but fat may be present Hair changes (thin, reddish, easily pulled out) Skin lesions and infections Irritability and apathy Delayed growth Treatment : Gradual reintroduction of protein Nutritional rehabilitation Treating infections Micronutrient supplementation 2. Marasmus Definition : Marasmus is a severe form of calorie (energy) deficiency , leading to extreme wasting of body tissues. Causes : Lack of all nutrients, especially calories and protein Chronic starvation Poverty, famin...

Liver function test

Liver function tests (LFTs) are a group of blood tests that provide information about the health and function of the liver. These tests are often ordered by healthcare professionals to assess the liver's overall well-being and to diagnose or monitor liver diseases. Here are some common markers included in liver function tests: Alanine Aminotransferase (ALT): Normal Range: 7-56 units per liter (U/L) Elevated levels may indicate liver damage or disease, such as hepatitis. Aspartate Aminotransferase (AST): Normal Range: 8-38 U/L Elevated levels may suggest liver damage, but AST is also found in other organs, such as the heart and muscles. Alkaline Phosphatase (ALP): Normal Range: 44-147 U/L (can vary with age and sex) Elevated levels may indicate liver or bone disorders. Gamma-Glutamyl Transferase (GGT): Normal Range: 9-48 U/L (can vary with age and sex) Elevated levels may be associated with liver or bile duct issues. Bilirubin: Total Bilirubin Normal Range: 0.3-1.2 milligrams per de...

Jaundice: classification, causes and differential diagnosis.

-
Image
Jaundice is a yellow discoloration of the skin, mucous membranes, and sclera of the eyes due to elevated levels of bilirubin in the blood. Bilirubin is a yellow pigment produced during the breakdown of red blood cells. Jaundice can be classified into three main types based on the underlying causes: Prehepatic (Hemolytic) Jaundice: Causes: Increased breakdown of red blood cells (hemolysis), leading to elevated unconjugated bilirubin. Conditions such as hemolytic anemia, sickle cell disease, and certain genetic disorders. Features: Elevated unconjugated bilirubin levels. Hemolysis markers such as increased lactate dehydrogenase (LDH) and decreased haptoglobin. Hepatic (Hepatocellular) Jaundice: Causes: Liver dysfunction impairs the processing and conjugation of bilirubin. Conditions such as viral hepatitis, alcoholic liver disease, cirrhosis, drug-induced liver injury, and certain inherited liver disorders. Features: Elevated levels of both conjugated and unconjugated bilirubin. Liver fu...
