Idiopathic Pulmonary Fibrosis, Stacey Rosselot

Nursing Student Class Projects (Formerly MSN)

Idiopathic pulmonary fibrosis (IPF) is a progressive, irreversible lung disease, characterized by chronic inflammation and fibroproliferation of the parenchymal cells of the lung that lead to chronic respiratory failure and ultimately death (Kotsianidis et al., 2009). IPF is more prevalent in men than in women and risk for disease increases after age 60. IPF is the most common form of idiopathic interstitial pneumonia and it affects over 100,000 persons in the United States alone (Ding et al., 2011). Most of IPF cases are considered to be unpredictable and sporadic in nature, however approximately 15-20% of cases have a family history …

Review Of The Effectiveness Of Tissue Plasminogen Activator For The Treatment Of Plastic Bronchitis In Patients With Fontan Physiology, Ruth Ferroni

Nursing Student Class Projects (Formerly MSN)

Plastic bronchitis is a condition characterized by the formation of bronchial casts ranging from small to large obstructions of the pulmonary airways. Cast formation is intricate and resembles a plastic, rubbery model of the airway it obstructs. Its form was first described by Galen (A.D. 131-200). One of the patient populations at risk for developing this rare complication are those with single ventricle disease who are surgically corrected to Fontan physiology. It is a very abnormal type of circulation that is suspect in the development of plastic bronchitis. The cellular composition of plastic bronchitis differs from the casts seen in …

Diagnosis, Pathophysiology, And Clinical Treatment Of A Patient With A Pheochromocytoma, Tricia L. Hale

Nursing Student Class Projects (Formerly MSN)

Hypertension is an extremely common diagnosis today. This condition can be caused by a multitude of factors, and can inversely cause numerous unfavorable processes in the body. One rare but significant source of hypertension is a tumor known as a pheochromocytoma, or PCC. This usually benign tumor is most often located on an adrenal gland, and can have a grave impact on the cardiovascular system. The tumor intermittently secretes an excess of the catecholamine norepinephrine, and if large enough, also secretes epinephrine [9]. These episodic bursts can cause extreme hypertension and tachycardia, leading to, at times fatal results. By understanding …

Enterococcus Faecalis Endocarditis: A Case Study, Torri Curtis

Nursing Student Class Projects (Formerly MSN)

Infectious endocarditis is an uncommon disease of the heart stemming from a bacterial or fungal infection on the endocardial surface of the heart or heart valve (Pierce, Calkins, & Thornton, 2012). From review of the literature, infective endocarditis is fairly uncommon and may be difficult to initially diagnose. Per Sabe, Shrestha, and Menon, occurrence of infective endocarditis (IE) is nearly 0.9-6.2 per 100,000 persons per year (2013). Several preexisting conditions such as aging, heart valve disease, implantable cardiac devices, a history of heart disease such as rheumatic fever, and invasive procedures can put a patient at higher risk for IE …

Craniocervical Arterial Dissection, Joseph Weisenberger

Nursing Student Class Projects (Formerly MSN)

The annual incidence for spontaneous carotid artery dissection (CAD) ranges from 2 to 3/100,000 patients and is even lower for a spontaneous vertebral artery dissection (VAD). Furthermore, there is only a .08% - .04% chance for the incidence of a traumatic dissection (TD), of the entire trauma population (Mortazvi, Verma, Tubbs, Harrigan, 2011). However, despite these low levels, CAD/VADs pose a serious threat to a patient’s plan of care if not identified and treated early.

Lymphedema: Pathophysiology, Diagnosis & Management, Bernadine Cruz

Nursing Student Class Projects (Formerly MSN)

Lymphedema is a disfiguring condition whose hallmark is progressive, increasing swelling which occurs as a result of the accumulation of protein rich fluid in interstitial spaces. Those individuals who are affected suffer from either primary lymphedema or secondary lymphedema; the pathophysiology of both conditions is similar. Lymphedema can be a chronic, acute, or transient alteration, which can eventually lead to keratinization of the skin. An increase in the incidence of lymphedema has also been observed with increase in levels of obesity.

Atrial Fibrillation Post-Lung Lobectomy, Laura Adorni

Nursing Student Class Projects (Formerly MSN)

According to the American Heart Association, atrial fibrillation affected 2.66 million individuals in the United States in 2010 and is expected to double by year 2050 (Sanoski, 2010, p. S11). Post-operative atrial fibrillation (POAF), a classification of atrial fibrillation (AF), can occur after thoracic surgery and is an ongoing source of morbidity and mortality (Imperatori et al., 2012). There is a 10-20% occurrence rate of POAF after non-cardiac surgery, such as a lung lobectomy, and a 40% incidence rate after a pneumonectomy (Omae & Kanmura, 2012, p. 429). Cardiovascular events such as heart failure, cerebral infarction, renal failure, and infection …

Myocardial Infarction (Mi) In Women, Samuel Agyenim Boateng

Nursing Student Class Projects (Formerly MSN)

Cardiovascular disease (CAD) is the most common cause of death for men and women in the US. The disease has been extensively studied in males (Gulati & Bairey Merz, 2012, p. 141). CVD poses an obvious challenge to the health of women. Coronary heart disease (CHD) is described as a "modern epidemic" (Banner, 2010, p. 3123). Although, the prevalence of CVD has prompted many studies for prevention and treatment, little is known about CVD in women. It Is now known that the mortality rates In women have surpassed that of men. Recent reports Indicate that CVD killed more women in …

Early Onset Alzheimer’S Disease In Individuals With Down Syndrome: Explored Theories Of Pathophysiology, Amanda Pack

Nursing Student Class Projects (Formerly MSN)

This presentation is a focus on some of the theories of the pathophysiology of early-onset Alzheimer’s Disease (AD) in individuals with Down Syndrome (DS). Down Syndrome, a genetic condition where an individual has a partial or full extra chromosome 21, is the most common chromosomal condition in the United States (National Down Syndrome Society (NDSS), 2012). Average life expectancy for individuals with DS has vastly increased in the last thirty years from age 25 to age 60 (NDSS, 2012). The extra chromosome genetically makes individuals with DS predisposed to certain conditions, including early onset dementia and AD, therefore as their …

Literary Research On Alport Syndrome, Shailendra Jain

Nursing Student Class Projects (Formerly MSN)

Alport syndrome is rare genetic disorder of the glomerulus in the kidneys that can be X-linked, Autosomal recessive, or Autosomal dominant in nature. Clinical manifestation includes hearing loss, hematuria, proteinuria, and hypertension (Cheungpasitporn, Kaewpoowat, Suksaranjit, Kittanamongkolchai, Srivali, Ungprasert, & Rangan, 2012). It is most common disease in males. A 24-hour urine specimen is usually obtained to check for proteinuria and elevated creatinine, which indicate acute renal failure (Cosgrove, 2012). A renal biopsy and ultrasounds is used to confirm the diagnosis of Alport Syndrome. Patients that are diagnosed with such disease require dialysis and referral to an ophthalmology and audiology. The …

Enterovirus D68, Kimberly Meyers

Nursing Student Class Projects (Formerly MSN)

Enterovirus D68 (EVD68) “belongs to the family Picornaviridae, genus Enterovirus, and species Human enterovirus D: (Kaida et al.,2011, para.2). It is a small nonenveloped RNA virus (Xiang et al., 2012). EVD68 “shares characteristics with rhinoviruses, such as infection of the respiratory tract and acid lability” (Lauinger et al., 2012). There is no specific treatment for EVD68. Since the infection is caused by a virus, antibiotics would be ineffective. There are no antiviral medications currently available to treat EVD68 (Herold, 2014). Treatment may include antipyretics, cough medicines, bronchodilators, oxygen, and mechanical ventilation if required.

Cerebral Venous Sinus Thrombosis (Cvst), Meghan N. Delong

Nursing Student Class Projects (Formerly MSN)

Cerebral venous sinus thrombosis (CVST) is an uncommon condition with incidence resulting in approximately 1-3 % of all strokes. Cerebral venous sinus thrombosis remains often unrecognized initially due to its vague manifestations of symptoms which range from isolated headaches to focal neurological signs and symptoms. CVST is slightly more common in women, particularly in the age group of 20 to 35, due to pregnancy, puerperium and oral contraceptive use (Stam, 2005).

Acute Pancreatitis, Laura Payne

Nursing Student Class Projects (Formerly MSN)

Acute pancreatitis is a common diagnosis seen in intensive care units worldwide. The incidence of pancreatitis has increased over the last decade. It ranks third amongst the gastrointestinal diseases resulting in hospital admissions. The destructive complications of pancreatitis make it a life-threatening disease. If pancreatitis progresses to the severe form the mortality rate significantly increase from one percent to upwards of thirty percent. Pancreatitis is associated with high rates of morbidity, mortality, and prolonged hospital admissions(Goozen, Besselink, Santroort, & Bollen, 2013). An increased understanding of the pathophysiology of pancreatitis has changed the approach to treatment from early surgical treatment to …

Ascaris Lumbricoides: The Unforeseen Diagnosis, Suzette Maynard

Nursing Student Class Projects (Formerly MSN)

Infections from Ascaris lumbricoides have become very prevalent in lesser developed countries. These infections are believed to migrate into the United States through the border with Mexico, and immigration from other countries, through increased world travel and international adoptions (Cardenas et al., 2010). A. lumbricoides have been found to cause cases in the United States, one being in Westerville, Ohio (J. Leonard, personal communication, September 6, 2014). As the world has become smaller, it has become imperative that as a nation we are able to prepare for infections that are popular outside the United States. The first step in preparing …

When Exercise Is A Pain In The Head, Rebecca D. Granger

Nursing Student Class Projects (Formerly MSN)

Headache is one of the five most common chief complaints in the US, resulting in nearly 5 million visits to the ED (Lange, 2011). With great variance in quality, etiology, pathophysiology, and as a potential indicator of a serious underlying problem, it is critical that these headaches be accurately diagnosed, primarily for rapid identification of life threatening factors, but also to offer treatment and education specific to the particular type of headache the patient is experiencing. This will result in better outcomes for the patient through better control and will subsequently save health care dollars by reducing ED visits and …

Activation Of C-Myc And Cyclin D1 By Jcv T-Antigen And Β-Catenin In Colon Cancer, Michael J. Ripple, Amanda Parker Struckhoff, Jimena Trillo-Tinoco, Li Li, David A. Margolin, Robin Mcgoey, Luis Del Valle

School of Medicine Faculty Publications

During the last decade, mounting evidence has implicated the human neurotropic virus JC virus in the pathology of colon cancer. However, the mechanisms of JC virus-mediated oncogenesis are still not fully determined. One candidate to mediate these effects is the viral early transcriptional product T-Antigen, which has the ability to inactivate cell cycle regulatory proteins such as p53. In medulloblastomas, T-Antigen has been shown to bind the Wnt signaling pathway protein β-catenin; however, the effects of this interaction on downstream cell cycle regulatory proteins remain unknown. In light of these observations, we investigated the association of T-Antigen and nuclear β-catenin …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Pancreatic NETs are rare tumors with multiple classification systems. Previous classification systems included tumor size, histologic grade, mitoses, Ki67, and metastases. The current WHO 2010 system utilizes mitotic rate and Ki67% to assign a grade. We compared the WHO 2004 and 2010 classification systems in predicting mortality and metastasis.

Pathologic parameters were used to classify 50 cases of Pancreatic NET according to the WHO 2004 and WHO 2010 systems. The relationship between the WHO 2004 and WHO 2010 grading was investigated using an exact Chi squared test. WHO grade categorization was next explored by vital status, by the exact method, …
