Today, our genes testify to these prehistoric liaisons. Last year, when the Neanderthal genome was finally sequenced, it emerged that everyone outside of African can trace 1 and 4 percent of their DNA from Neanderthals. The discovery was a vindication for some and a surprise to others.
CCK Diseases of the pancreas Due to the importance of its enzyme contents, injury to the pancreas is potentially very dangerous. A puncture of the pancreas generally requires prompt and experienced medical intervention. Diseases associated with the pancreas include: Diabetes mellitus Diabetes mellitus is a metabolic disorder characterized by hyperglycemia.
All three forms of the disease are due to the inability of the beta cells of the pancreas to produce sufficient insulin.
Researchers at the Toronto Hospital for Sick Children injected capsaicin into NOD mice Non-obese diabetic mice, a strain that is genetically predisposed to develop the equivalent of diabetes mellitus type 1 to kill the pancreatic sensory nerves. When the researchers injected the pancreas of the diabetic mice with sensory neuropeptide sPthey were cured of the diabetes for as long as 4 months.
Also, insulin resistance characteristic of diabetes mellitus type 2 was reduced. Benign tumors Like any other organ, the pancreas is susceptible to the growth of benign tumors. Benign tumors do not invade neighboring tissues, do not cause metastases, and usually do not return after surgical removal.
Pancreatic cancer Pancreatic cancer is a malignant tumour within the pancreatic gland. Its prognosis is generally regarded as poor. The different types of pancreatic cancers include: Tumors of the centroacinar cells.
Other tumors of the exocrine pancreas, such as serous cystadenomas. They are a type of Neuroendocrine tumors. Examples of functioning PET's include: Gastrinoma, producing excessive gastrin and causing Zollinger-Ellison Syndrome ZES Insulinoma, producing excessive insulin Vasoactive intestinal peptideoma VIPomaproducing excessive vasoactive intestinal peptide VIP PPoma, producing excessive pancreatic polypeptide often classed with non-functioning PETs Somatostatinoma, producing excessive somatostatin CRHoma, producing excessive corticotropin-releasing hormonse CRH Calcitoninoma, producing excessive calcitonin GHRHoma, producing excessive growth-hormone-releasing hormone GHRH Neurotensinoma, producing excessive neurotensin ACTHoma, producing excessive adrenocorticotropic hormone ACTH GRFoma, producing excessive growth-hormone release factor GRF Parathyroid hormone—related peptide tumor Cystic fibrosis Cystic fibrosis, also known as mucoviscidosis, is a hereditary disease that affects the entire body, causing progressive disability and early death.
There is no cure for cystic fibrosis, and most affected individuals die young from lung failure. Cystic fibrosis is caused by a mutation in a gene called the cystic fibrosis transmembrane conductance regulator CFTR. The product of this gene helps create sweat, digestive juices, and mucus.
Although most people without CF have two working copies of the CFTR gene, only one is needed to prevent cystic fibrosis.
Cystic fibrosis develops when neither gene works normally. Therefore, it is considered an autosomal recessive disease. The name cystic fibrosis refers to the characteristic 'fibrosis' tissue scarring and cyst formation within the pancreas.
Cystic fibrosis causes irreversible damage to the pancreas, which often results in painful inflammation pancreatitis. Exocrine pancreatic insufficiency Exocrine pancreatic insufficiency EPI is the inability to properly digest food due to a lack of digestive enzymes made by the pancreas.
EPI is found in humans afflicted with cystic fibrosis. It is caused by a progressive loss of the pancreatic cells that make digestive enzymes.
Chronic pancreatitis is the most common cause of EPI in humans. Loss of digestive enzymes leads to maldigestion and malabsorption of nutrients.
Hemosuccus pancreaticus Hemosuccus pancreaticus, also known as pseudohematobilia or Wirsungorrhage, is a rare cause of hemorrhage in the gastrointestinal tract.
It is caused by a bleeding source in the pancreas, pancreatic duct, or structures adjacent to the pancreas, such as the splenic artery, that bleed into the pancreatic duct.
Patients with hemosuccus may develop symptoms of gastrointestinal hemorrhage, such as blood in the stools, maroon stools, or melena. They may also develop abdominal pain. Hemosuccus pancreaticus is associated with pancreatitis, pancreatic cancer and aneurysms of the splenic artery.
Angiography may be used to treat hemosuccus pancreaticus, where the celiac axis is injected to determine the blood vessel that is bleeding, because embolization of the end vessel may terminate the hemorrhage. Alternatively, a distal pancreatectomy may be required to stop the hemorrhage.
Pancreatitis Pancreatitis is inflammation of the pancreas. There are three forms of pancreatitis, which are different in causes and symptoms, and require different treatment: A rapidly-onset inflammation of the pancreas. A long-standing inflammation of the pancreas.The social context of schistosomiasis and its control An introduction and annotated bibliography Birgitte Bruun1 Jens Aagaard-Hansen2 Foreword by3 Susan Watts3 1 Medical anthropologist, DBL – Centre for Health Research and Development, University of Copenha- gen, Copenhagen, Denmark.

Schistosomiasis, also known as bilharzia, is a neglected tropical disease caused by parasitic worms. It is second only to malaria as the most devastating parasitic disease.
