Anthrax Anthrax is an infection that is caused by the gram-positive bacteria called Bacillus Anthracis. Anthrax can either be cutaneous, gastrointestinal or inhalation. History Anthrax was known by the names wool sorters and rag-pickers disease in 1800. This was because workers used to contract the disease through bacterial spores present in wool or fabric fibres. Spores are small thick-walled in the dormant stage of some … Continue reading Explainer | What is Anthrax and why is it dangerous?
Fluid and Nutritional imbalance in children and young people Children have a higher metabolism so they need more calories and fluid for growth The intestinal tract in children is larger per body weight compared to adults. Gastric acid secretion reaches adult levels by 10 years of age. Infants have a short oesophagus At three months pancreatic juice contains low levels of lipase Nutritional assessments Is … Continue reading Fluid and Nutritional Imbalance in Children
Haemodynamic disorders, Thrombosis and Shock Haemodynamic in biology is how blood flows through the cardiovascular system Haemodynamic is also related to cardiac output (perfusion pressure differences at various parts of the system and peripheral vascular resistance (the different perimeters combining to affect the blood flow in each organ) Haemodynamic disorders Maintenance of a normal fluid balance is very important for survival. A large part of … Continue reading Haemodynamic disorders, Thrombosis and Shock
There are an estimated 1.2 million people, living with diabetes and 85 per cent of them have type two, while the other 13 per cent have type 1 (Australian Government Department of Health, 2016). Genetics play a big part in the development of type 1 diabetes, which is an autoimmune condition where the body’s immune system attacks the insulin-producing cells of the pancreas. Destruction … Continue reading Case Study| Type 1 Diabetes
ACS happens when a disrupted atherosclerotic plaque in the coronary artery stimulates platelet aggregation and the formation of the thrombus. It is the thrombus that forms in the tissue that prevents myocardial perfusion. In the past researchers thought that it is primarily the narrowing the coronary artery that causes a reduction in blood flow. But more recent studies indicate it is the rapture of the … Continue reading Pathophysiology of Acute Coronary Syndrome
Oesophagitis Can be caused by the reflux of acid from the stomach through the cardiac sphincter initially causing heartburn, but long-term reflux causes bleeding, ulcer formation and scarring. The scarring can cause the narrowing of the oesophageal passage which results in problems swallowing Hiatus Hernia Sometimes called a sliding hiatus hernia happens when part of the stomach slides through the diaphragmatic opening that … Continue reading Gastrointestinal Tract Pathologies
Haemodynamic in biology is how blood flows through the cardiovascular system. Haemodynamics is also related to cardiac output (perfusion pressure differences at various parts of the system and peripheral vascular resistance (the different perimeters combining to affect the blood flow in each organ) Haemodynamic Disorders Maintenance of a healthy fluid balance is very important for survival. A large part of each cell is made of … Continue reading Haemodynamic Disorders| Thrombosis, Infarction and Shock
