A 50-year-old man, who is a chronic alcoholic, presents to the emergency room with a sudden onset of abdominal pain that radiates to the back. A blood test reveals elevated serum pancreatic lipase levels and a CT abdomen suggests inflamed pancreas. Both of these findings together confirm the diagnosis of acute pancreatitis. The patient was admitted and appropriately managed. The pain reduces over the next two days. On day 3, the patient reports worsening of pain, nausea, and vomiting. An emergency CT abdomen was ordered, and the images reveal a pseudocyst around the pancreas. A pancreatic pseudocyst is a cavity surrounding the pancreatic head filled with pancreatic enzymes and is a common complication following acute pancreatitis. In a few hours following the diagnosis, the patient’s symptoms worsen, develops a fever, hematemesis (blood vomiting), cold and clammy skin, multi-organ failure, and dies. As a physician, you think that the patient developed these complications and died because the pancreatic pseudocyst ruptured. Based on the knowledge learned in this course, provide an explanation as to why this rupture led to complications and death of the patient.

Clue: Think about what the functions of pancreatic enzymes are, and why these enzymes are secreted first in an inactive form and not directly in an active form.

David, a 55 year old high school teacher is a heavy smoker with really poor eating habits. He was admitted to the ER a week ago because he was experiencing symptoms including shortness of breath, chest pain, weakness in his left arm and left leg. He was rushed to the Coronary Care Unit, where clinicians performed Electrocardiogram (ECG) and arteriogram tests. Results showed 80% occlusion of the left main coronary artery.

1. What condition does he have? a) dilated cardiomyopathy, b) atherosclerosis, c) myocardial infarction, d) cardiac arrhythmia, e) endocarditis

2. Which treatment is David most likely to receive for this condition?

3. What are the risk factors for this condition?

4. What are the underlying mechanisms (causes) that result in this condition?

Acquired (adaptive) immunity allows the immune system to respond to a large number of antigens with a strong targeted response. Please briefly explain this statement

give me REFERENCE to these question with APA 7....in text format, please....

1: Minute arteries bring blood to areas deep inside the brain. Hypertension can cause minute arteries to rupture, releasing blood into the brain tissue. An intracerebral hemorrhage is usually caused by rupture of tiny arteries within the brain tissue. Ans 2: At the base of the brain, the carotid and vertebrobasilar arteries form a circle of communicating arteries known as the Circle of Willis. From this circle, other arteries—the anterior cerebral artery, the middle cerebral artery , the posterior cerebral artery arise and travel to all parts of the brain. Because the carotid and vertebrobasilar arteries form a circle, if one of the main arteries is occluded, the distal smaller arteries that it supplies can receive blood from the other arteries. The anterior cerebral artery extends upward and forward from the internal carotid artery. It supplies the frontal lobes, the parts of the brain that control logical thought, personality, and voluntary movement, especially of the legs. The middle cerebral artery is the largest branch of the internal carotid. The artery supplies a portion of the frontal lobe and the lateral surface of the temporal and parietal lobes, including the primary motor and sensory areas of the face, throat, hand and arm, and in the dominant hemisphere, the areas for speech. The posterior cerebral arteries stem in most individuals from the basilar artery but sometimes originate from the ipsilateral internal carotid artery. Small, deep penetrating arteries known as the lenticulostriate arteries branch from the middle cerebral artery Occlusions of these vessels or penetrating branches of the Circle of Willis or vertebral or basilar arteries are referred to as lacunar strokes. Ans 3: The affected pupil does not immediately respond to direct or consensual light reflex; however, if light stimulus is prolonged, this pupil will slowly constrict to light and slowly dilate in the dark. Accommodation in the affected pupil is sluggish. The other pupil is of normal size and reacts to light. Ans 4: Smoking. Smoking is linked to both the development and rupture of cerebral aneurysms. Smoking may even cause multiple aneurysms to form in the brain. High blood pressure. High blood pressure damages and weakens arteries, making them more likely to form and to rupture. Size. The largest aneurysms are the ones most likely to rupture in a person who previously did not show symptoms. Family history. A family history of aneurysm rupture suggests a higher risk of rupture for aneurysms detected in family members. Ans 5: An end artery/ terminal artery is an artery that is the only supply of oxygenated blood to a portion of tissue. Because vital tissues such as the brain or heart muscle are vulnerable to ischaemia, arteries often form anastomoses to provide alternative supplies of fresh blood. Comment
