The document discusses the endocrine system and cystic fibrosis. It explains that cystic fibrosis is a hereditary disease that causes thick mucus to accumulate in the exocrine glands and associated organs like the lungs and pancreas. In the lungs, the thick mucus promotes bacterial growth and leads to constant infections that damage the tissue over time and cause lung disease. In the pancreas, the thick mucus blocks the release of enzymes, preventing nutrients from being absorbed and causing symptoms like weight loss and abdominal pain. The document also discusses hypocalcemia, a condition of low calcium levels in the blood that can be caused by various diseases and has symptoms like tingling, muscle contractions, and irregular heartbeat.

Urinary system
The urinary system consists of the kidneys, ureters, bladder, and urethra. The kidneys filter waste from the blood to produce urine, which travels through the ureters to the bladder. When full, the bladder contracts to expel urine through the urethra. Hematuria is the presence of blood in urine, which can be caused by minor issues but sometimes indicates tumors. Vesicoureteral reflux involves urine flowing back up from the bladder into the kidneys, potentially causing infections or kidney damage over time. It is sometimes genetic and more common in boys.
1 Digestive system
The digestive system consists of the alimentary tract and accessory organs. The alimentary tract includes the mouth, esophagus, stomach, small intestine, and large intestine. Accessory organs include the teeth, tongue, liver, gallbladder and pancreas. The stomach contains gastric glands that secrete acid and enzymes to digest food. The small intestine further breaks down food with the help of enzymes from the pancreas and bile from the liver. The large intestine absorbs water before waste is excreted through the anus.
Liver failure
This document discusses liver failure, distinguishing between acute liver failure caused by things like infection or drugs versus chronic liver failure usually caused by alcohol or viral hepatitis. In chronic liver failure, functional problems develop like low clotting factors and encephalopathy, while plumbing issues in the liver lead to increased portal vein pressure and blood shunting to other areas, causing complications like esophageal varices and GI bleeding. Long term prevention of bleeding focuses on beta blockers or surgical shunting.
Disorders of the biliary tract
The document discusses several disorders of the biliary tract, including cholecystitis (inflammation of the gallbladder), cholelithiasis (gallstones), and gallbladder cancer. Cholecystitis is usually caused by a gallstone blocking the cystic duct and can cause pain, fever, and leukocytosis. Cholelithiasis involves the presence of cholesterol or pigment gallstones that can be detected by ultrasound or CT scan. Gallbladder cancer is rare and symptoms are often similar to other biliary disorders initially, but later include biliary obstruction.
.jaundice
Jaundice is caused by an increase in serum bilirubin levels, seen as a yellowish discoloration of the skin and eyes. It can be due to excessive bilirubin production, impaired hepatic uptake or conjugation, or impaired bile flow out of the liver. The main types are unconjugated hyperbilirubinemia affecting liver function and conjugated hyperbilirubinemia due to biliary obstruction. In neonates, high bilirubin levels can cause kernicterus, toxic brain damage most common in hemolytic diseases or conjugation enzyme deficiencies. Phototherapy is used to treat neonatal jaundice by accelerating bilirubin breakdown and excretion.
CHOLEMIC SYNFROME, ACHOLIC SYNDROME,PSYCHOLIA
Cholemia is a condition caused by the presence of excess bile in the blood. Its symptoms can include somnolence (drowsiness), yellow tinge to skin and whites of eyes, fatigue, nausea and, in extreme cases, coma. It is often an early sign of liver disease.

Chapter22 digestivepart2marieb
The document summarizes key aspects of the digestive system, including:
1) It describes the general organization of the digestive tract into four layers - mucosa, submucosa, muscularis externa, and serosa.
2) It outlines the regions and functions of the small intestine - duodenum, jejunum, and ileum. Most absorption occurs in the small intestine.
3) It discusses the large intestine/colon and its regions - ascending, transverse, descending, and sigmoid colon. The colon has fewer villi and glands than the small intestine.
4) It briefly covers the liver, gallbladder, and pancreas - their locations, functions, histology
Secretions of small intestine
The small intestine has four layers and is divided into three regions: the duodenum, jejunum, and ileum. Its interior walls contain circular folds, villi, and microvilli that greatly increase its surface area for nutrient absorption. The small intestine secretes enzymes like enterokinase in the duodenum as well as hormones like gastrin, cholecystokinin, and secretin from endocrine cells in response to food constituents. These secretions aid in digestion and regulate secretions from other organs to maximize nutrient absorption in the small intestine.
Furosemide
Diuretics work by preventing the body from absorbing too much salt and increasing the excretion of water and salt in urine. Furosemide is a common diuretic ("water pill") that is prescribed to treat high blood pressure and reduce excess fluid in the body from conditions like heart failure or kidney disease. It works by inhibiting sodium reabsorption in the ascending loop of the kidney, which leads to increased water excretion in urine. Potential side effects include headaches, dizziness, thirst, and electrolyte imbalances.
Cystic fibrosis
Cystic fibrosis is a genetic disorder that causes thick, sticky mucus to build up in the lungs and digestive tract. It is caused by a defective gene that affects the cells that produce mucus, sweat, and digestive juices. The main symptoms involve the lungs and digestive system, including persistent cough, wheezing, difficulty breathing, and problems with weight gain and growth. Treatment focuses on loosening and clearing mucus from the lungs and digestive tract through chest physiotherapy, medications, enzyme supplements, and managing infections and complications. For severe cases, lung transplantation may be required.
Cystic fibrosis
Cystic fibrosis is a genetic disorder that causes thick, sticky mucus to build up in the lungs and digestive tract. It is caused by a defective gene that disrupts chloride transport in epithelial cells. Individuals must inherit one defective copy of the gene from each parent to be affected. The mucus clogging leads to lung infections and impaired digestion. While historically fatal in childhood, treatment advances have improved life expectancy to over 38% of individuals living past age 18. Care involves airway clearance techniques, antibiotics, nutrition support, and potentially lung transplantation.
cystic fibrosis
Cystic fibrosis is caused by a genetic defect in the CFTR gene that codes for a chloride channel protein. Malfunction of this protein disrupts ion transport in epithelial cells leading to thick mucus in the lungs, pancreas and other organs. In the lungs, mucus buildup causes chronic infections and inflammation eventually leading to structural damage. The pancreatic defect causes malnutrition by inhibiting digestive enzyme function. Other manifestations include sinus issues, intestinal obstruction and male infertility. Diagnosis involves sweat testing and symptoms affecting the lungs, pancreas and other organs.

Cystic fibrosis
Cystic fibrosis is an autosomal recessive genetic disorder that affects the exocrine glands and causes thick, sticky mucus to build up in the lungs, digestive tract, and other areas of the body. It is caused by mutations in the CFTR gene that encodes a chloride channel protein. The most common mutation is Delta F508. Symptoms involve the respiratory and gastrointestinal systems and include chronic lung infections, poor growth, and fatty stools. Diagnosis involves sweat testing and genetic testing. Treatment requires a multidisciplinary approach including airway clearance techniques, antibiotics, nutrition support, and potentially lung transplantation in severe cases.
Cystic Fibrosis. GIT Manifestations. Diagnosis. Treatment
Cystic fibrosis is a genetic condition that causes thick, sticky mucus to build up in the lungs and digestive tract. This mucus clogs the lungs and leads to infections, and blocks the pancreas which causes issues absorbing nutrients. The main symptoms are issues with the lungs like infections, coughing, and shortness of breath as well as problems with digestion like poor growth and weight gain. There is no cure, but treatments focus on clearing the lungs of mucus, treating infections with antibiotics, using enzymes to aid digestion, and potentially lung or liver transplants in severe cases.
Cystic Fibrosis
This document provides information about cystic fibrosis, including how it is diagnosed. It discusses:
1. Cystic fibrosis carrier detection testing, which detects mutations in the CFTR gene and is used for cystic fibrosis screening. Samples collected can include blood, buccal cells, or chorionic villus.
2. The procedures for each sample type - a blood draw from the vein, swabbing the inside of the cheek, or chorionic villus sampling during pregnancy using ultrasound guidance.
3. The potential discomfort from each procedure, from mild pain during blood draw to cramping for chorionic villus sampling. Proper preparation and follow up care is also discussed.
Cystic fibrosis
Cystic fibrosis is a genetic disease that causes thick, sticky mucus to build up in the lungs and digestive tract. It is caused by a mutation in the CFTR gene and results in problems absorbing nutrients and frequent lung infections. Symptoms include salty-tasting skin, coughing, wheezing, and poor growth. It is diagnosed via sweat and genetic tests. Treatment focuses on clearing mucus from the lungs using antibiotics, physiotherapy, and inhaled medications. Enzyme supplements and nutrition are also important to manage digestive issues. Life expectancy has increased in recent decades but most still have reduced longevity compared to those without cystic fibrosis.

CYSTIC FIBROSIS
Cystic fibrosis is a genetic disorder that affects the lungs and digestive system. It is caused by a defective gene that causes thick, sticky mucus to build up in the lungs, liver, pancreas, and other organs. On radiological evaluation, chest x-rays and CT scans are used to examine lung abnormalities like bronchial wall thickening, bronchiectasis, mucus plugging. Abdominal imaging reveals pancreatic abnormalities such as cysts and atrophy as well as hepatobiliary manifestations like cirrhosis and gallstones. Imaging also detects gastrointestinal complications including meconium ileus in newborns, distal intestinal obstructive syndrome, and intussusception.
My presentation on genetics (DISEASE)
Cystic fibrosis is a genetic disease that causes thick, sticky mucus to build up in the lungs and digestive tract. It is caused by a mutation in the gene that regulates chloride and sodium transport across epithelial cell membranes. This mutation leads to defective protein production and the formation of thick mucus in the lungs, pancreas and other organs. Common symptoms include persistent coughing, breathing difficulties, fatigue, and frequent bowel movements. While there is no cure, treatment can help manage symptoms and slow the progression of the disease. Cystic fibrosis affects approximately 3,000 people in Australia and is typically diagnosed through newborn screening or shortly after birth.
GI FISTULA.ppt
This document defines gastrointestinal fistulas and outlines their classification, causes, symptoms, treatment approach, and complications. It describes how fistulas are abnormal connections between the GI tract and other organs or skin. Treatment is organized into four phases - stabilization, investigation, conservative management, and definitive surgery. The goal of stabilization is resuscitation, sepsis control, nutrition, and drainage management. Conservative treatment aims to allow spontaneous closure, while surgery is indicated for failed non-operative treatment or complex fistulas. Prognosis depends on factors like etiology, nutrition status, and sepsis control.
Cystic fibrosis
Cystic fibrosis is a genetic disorder characterized by thick, sticky mucus buildup in the lungs, pancreas, and other organs. It is caused by mutations in the CFTR gene that result in defective or too few chloride channels at the surface of epithelial cells. This leads to dehydrated mucus and mucus plugging of various organs. Common manifestations include chronic lung infections and pancreatic insufficiency. Treatment involves airway clearance techniques, antibiotics, nutritional support, and other therapies to target specific organ involvement. Management requires a multidisciplinary team approach and focuses on optimizing growth, delaying lung disease progression, and treating complications to improve quality of life.

Cystic fibrosis is a genetic, autosomal recessive disorder that affects the exocrine glands in the lungs, pancreas, and intestines, causing them to produce abnormally thick mucus. Common symptoms include salty-tasting skin, persistent coughing, wheezing, frequent lung infections, difficulty breathing, and digestive issues like fatty stools and poor growth. Diagnosis involves newborn screening, sweat tests, imaging, and pulmonary/digestion function tests. Treatment focuses on airway clearance techniques, antibiotics, nutrition supplements, enzymes, exercise, and genetic counseling to promote optimal health and slow disease progression.

Identification and nursing management of congenital malformations Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
