Renal artery stenosis

Chest radiography plays an important role in the detection and diagnosis of disease related to lungs. The chest radiograph specifies the thoracic anatomy and provides high yield, at the low cost [1]. There are some challenges in processing Chest X-ray images. For example, in lung segmentation, the strong edges at the rib cage and clavicle region cause local minima for most minimization approaches. Segmenting the lung apex is also a nontrivial problem because of the changing intensity at the…

starts sprinting his heart would pump blood around his body and this would increase progressively whilst he starts running. The systolic blood pressure is the highest pressure in the bloodstream. 2. The diastolic blood pressure is there so that the arteries can resist the blood flow. A sport example of diastolic blood pressure could be marathon runners, the blood flow would be resisted and would stay the same; it only occurs between beats. The diastolic blood pressure is the lowest pressure in…

1. What were the main findings of Mr. Penzey’s physical exam? How could his CT results be related to his blood pressure findings? A physical examination for high blood pressure also comprises a medical history. The extent of the physical examination as well as the level of detail in your doctor's questions depend on how high your blood pressure is in addition to whether you have other risk factors for heart disease. High blood pressure can harm your blood vessels, heart as well as kidneys. This…

The social stigma that was mentioned in a story that we read called “The Yellow Wallpaper” was dementia. This disease is a group of thinking and social symptoms that interfere with daily functioning. It cannot be cured, but treatment can help and it can last for years or a lifetime. Symptoms of dementia may include forgetfulness, limited social skills, and thinking abilities so impaired that it will affect the daily lives of those who contract it. This disease can be caused by brain disease or…

The body is a complex organism, which is composed of systems that work together to maintain homeostasis. The immune and lymphatic system is one of the systems that protect the body from disease-causing bacteria, viruses and organisms. There are two ways that they fight and protect the body from disease, nonspecific and specific. Nonspecific is how the body generally fights off diseases. This includes fever and the swelling of your lymph nodes. Specific immunity is how the body protects itself…

Peripheral artery disease (PAD), also known as arterial occlusive disease, is the obstruction or narrowing of aortic passages--including lumen and its major branches. This blockage interrupts blood flow, usually to the feet and legs. The prognosis will vary depending on the occlusion's site. The symptoms vary depending on the location of the occlusion. For example: in femoral arteries, having pain in the feet, no pulse in ankles and feet, and pallor or coolness in legs are symptoms.…

receptors represent the majority of intracellular Ca²+ channels in cardiomyocytes and arbitrate a process known as Ca²+ induced Ca²+ release. The free Ca²+ binds to the troponin C present on the actin-containing thin filaments of myofibrils. Troponin proteins consists of three different subunits, Troponin T, Troponin I, and Troponin C, with each subunit being responsible for a different part of troponin function. Troponin T is a tropomyosin-binding subunit and hence regulates the interaction of…

Incidence of difficult intubation Difficult tracheal intubation contributes greatly to anaesthesia related morbidity and mortality. The principal adverse outcomes associated with the difficult airway include brain injury, cardiopulmonary arrest, unnecessary tracheostomy, airway trauma, damage to teeth and death8,9 The incidence of failed tracheal intubation ranges from 1 in 1000–2000 cases in the elective setting10,3. Failed and difficult tracheal intubations are associated with…

SUMMARY Airways Turn the victim on to their back and then open the airway using head tilt and chin lift: Place your hand on their forehead and gently tilt their head back. With your fingertips under the point of the victim's chin, lift the chin to open the airway. Airway obstruction is an emergency. Get expert help immediately. Untreated, airway obstruction causes hypoxia and risks damage to the brain, kidneys and heart, cardiac arrest, and death. Look for the signs of airway obstruction: •…

A reaction in a person exposed to an allergen is known as anaphylaxis ("Anaphylaxis | Causes, Symptoms & Treatment | ACAAI Public Website," n.d.). There are two types of reactions a person experiencing anaphylaxis can have, uniphasic in which symptoms come quickly, get rapidly worse, but once treated symptoms go away and don't return. The other reaction type is called bi-phasic, where symptoms start and go away for a period of time, then return with increasing symptoms. The most common causes…
