Essays on Ultrasonography

Radiography can be defined as the science of making film records from X-rays, also known as radiographs of the human body’s internal anatomy, by exposing a film that has been sensitized to electromagnetic radiation to the body. It is with these photographs that a record is made out of the findings which are used for examination in the diagnostic processes (Hertrich, 2005). It was formally referred as ‘plain’ X-rays but was switched to the use of electromagnetic radiation because it is the suitable general term that covers the other types of medical imaging like ultrasound. Radiography is usually ...

The diagnostic medical Sonographer is a well-trained individual who operated the computers and machines to administer an image scan of ...

Discussion Questions on Clinical Nursing

1. The cephalosporins are a family of bactericidal antibiotics structurally related to penicillin which were first derived from the fungus, Cephalosporum acremonium. 

Cephalosporins are the most frequently prescribed class for antibiotics (eMedexpert, 2011). This class’ mode of action is similar to other beta-lactam antibiotics, such as penicillins and cephamycins. Every form of bacteria cell has a certain cell wall for protection. Cephalosporins disrupt the synthesis of the peptidoglycan layer of bacterial cell walls, which makes the bacteria cell walls break down and the bacteria eventually die (eMedexpert, 2011). One intravenous (IV) drug under this class is cefazolin. For adults, dosage for ...

VTE Nursing Research

Venous Thromboembolism Introduction Venus thromboembolism (VTE) is a condition that includes both pulmonary embolism (PE) and deep vein thrombosis (DVT). DVT commonly occurs when blood clots in deep veins normally in the pelvic veins or in the legs. However, VTE is common any vein in the human body. Patients who develop VTE have a 35% to 65% chance of dying from it. It is important to research on Venus thromboembolism (VTE) because as the third most common cardiovascular disease, it is a leading cause of mortality and mobility worldwide. VTE results from slowing of the blood flow (stasis), damage of ...

Venous Thromboembolism: Literature Review

Venous Thromboembolism: Literature Review

Venous Thromboembolism (VTE) is a health condition characterized by blood clot forming within the veins. VTE is the third most common cardiovascular condition and is fatal for up to 35% of patients who develop the condition (Deitelzweig, Johnson & Schulman, 2011). This high mortality rate is as a result of poor understanding of VTE unlike arterial thrombosis which is well understood. Although many risk factors have been identified to cause VTE, thrombophilia is one of the underlying cause that characterizes many cases of VTE. Thrombophilia is an abnormality in the ability of blood to clot. The problem which ...

Captive Breeding of Marine Mammals: Challenges and Mitigating Measures

Introduction The growing demand to sustain the current lifestyle of the human population puts an added strain to the natural resources of the world. The increase in the exploitation of tropical forests and marine communities leads to a series of habitat destruction thereby leaving thousands of species of both terrestrial and marine animal homeless (Soule et al., 1986). Since 1986, there are already about nineteen percent and nine percent of the world’s mammals and birds respectively that are bread by zoos as per the International Zoo Yearbook Census. Based on the International Species Inventory System, there are about ...

Abstract

Cirrhosis is 12th on the list of leading causes of death in the US. Cirrhosis is characterized by scarring of the liver tissue due to inflammation that could lead to liver failure and death. Some patients develop cancer in due course of the illness. The scarring, which is usually permanent, covers the outer layer with collagen, makes the liver very rigid and limits the exchange of blood between the portal vein and the liver, thereby creating excess pressure in the hepatic portal vein. The scarring renders the removal of toxin such as alcohol difficult due to depletion of hepatocytes. ...

Pancreatic cancer (PC) is a malignant cancer that originates from cancerous cells in the pancreas. It has been estimated that 90-95% of pancreatic cancers are adenocarcinomas that originate from the exocrine part of the pancreatic tissue. Adenocarcinomas (ductal pancreatic cancer) are tumors that exhibit glandular architecture when observed under a light microscope. Pancreatic carcinoma accounts for fourth highest occurrence of cancer related deaths in the United States. The prognosis for the various stages of pancreatic cancer is poor with an estimated 25% survival rate for a person diagnosed with stage 1, while only 5-6% survival rate estimated for a stage 5 diagnosis according ...

Urolithiasis refers to the condition where there is the formation of urinary stones as well as their location in the urinary system. While the term urolithiasis refers to those stones that are in the ureter, nephrolithiasis also known as renal calculus refers to those stones that are found in the kidney, and cystolithiasis (vesical calculi) refers to the stones that are formed or located into the urinary bladder (Pearle, Calhoun, & Curhan, 2007). The urinary stones also known as calculi refer to the hardened mineral deposits forming in the kidney. The stones originate as microscopic after which they develop ...

Part 5: Final Draft

This paper has several sections. First, it gives an analysis of a psychological report which was published in popular media. The second part documents the original research cited in the psychological report in section one. The third step gives a comparison between the first and second report.

Analysis of a Psychological Report

The title of the report was Silent Cerebral Emboli May Hasten the Progression of Dementia (Journal Watch, 2012). The author notes that the findings of the report were drawn from two groups: patients with dementia (loss of cognitive ability particularly, memory, attention, and language) and patients with Alzheimer disease. The author begins by notifying ...

Introduction

The urinary bladder is a hollow organ in the pelvis that stores urine for a temporary period until it is passed during urination. Bladder cancer is a common cancer affecting the urinary system; and bladder is the most commonly affected cancer site in the urinary system. Most of the bladder cancers originate at the urothelium, which is a layer of mucosa lining the bladder (cancer.net). It is very common in the regions of the Americas, Europe, and Asia. Squamous cell carcinoma is the second most common carcinoma. Approximately, 2% of bladder cancers are adenocarcinomas and 0.3% to0.7% are small cell carcinomas(Medscape).

Placenta Accreta

Introduction During pregnancy, the placenta is normally supposed to attach on the surface of uterine wall. There are instances when the placenta attaches itself so deeply on the uterine. Placenta accreta is an abnormal attachment of the placental villi to the uterine in which the placenta is attached unusually deeply into the uterine wall. In placenta accreta, the placenta is attached directly on the myometrium unlike in other variant accounts when it gets attached into the myometrium (hence the name placenta increta) or goes through the myometrium (hence the name placenta percreta). Apparently placenta accreta is the most ...

Abstract

Computed Tomography CT refers to an imaging procedure that has been popular over the last decade in the imaging of the human body. In coronary artery imaging, this procedure is called Computed Tomography Coronary Angiography (CTCA). This technique is used specifically in the imaging and assessment of the cardiac and coronary anatomy to determine if one has a coronary artery disease or to determine the extent to which the individual has been affected by the disease. This procedure is also used to evaluate the coronary arteries and their anatomy. There are also other methods or techniques that are used in ...
