The etiology of type 1 diabetes has been identified to be associated with at least ten different genes. Carel (2010) states that “the known functions of these genes indicate the primary etiological pathways of this disease including HLA class H and I molecules binding to preproinsulin peptides and T-cell receptors, T- and B-cell activation, innate pathogen-viral responses, chemokine and cytokine signaling and T-regulatory and antigen presenting cell functions” (p. 218). 2. Assess the patient’s physical examination. What is consistent with diabetic ketoacidosis (DKA) and give the physiological rational for all that you identify? The case study states that his symptoms were ‘fatigue, nausea, vomiting, and intense thirst. The ER physician noticed that his breath smelt of acetone’. Only about 30% of the population can smell the scent of acetone in a patient in DKA, so the patient was lucky on this count. The signs of fatigue, nausea, vomiting and intense thirst are only the beginning of the diagnosis, but the scent of acetone leads the diagnosis in that direction. His dryness and the noticeable irritability can also be signs of DKA. The difficulty that he is having breathing coupled with the existence of a fever for the last two weeks also suggest that he has dropped into a state of DKA. Although he has a history of taking care of himself nutritionally, he has lost weight (15.4 lbs) which also suggests that he is in DKA. 3. Examine the biochemical indices of the patient and list which are consistent with DKA and discuss why. In the incidence of DKA, certain biochemical measures will be shifted, primarily as a counterbalance to regulation of insulin through hormone shifts. Examples of these shifts can be seen in epinephrine, growth hormone, the plasma levels of glucagon and increases in cortisol. The changes in these chemicals are usually due to an insufficiency of insulin. The result is hyperglycemia which occurs as the production of ketone production increases. Glucose is decreased in being drawn into the tissues and gloconeogenesis and glycogenolysis are increased. Lipolysis is triggered due to the counter-regulatory hormones which are caused by the increased ketogenesis. As a result, low pH and low bicarbonate is the result of being consumed through the resulting buffering of the keto acids. Respiratory distress is caused by metabolic acidosis (Joshi & Mishra, 2009). Potassium and chloride will be in short supply during DKA, which is being shown in the patient. Phosphorus is increased, which is not normal for DKA. Mental status is known to change when osmolality is over 340 and the patient is dangerously close to that level when he is admitted, with CO2 levels being low which is due to the breathing difficulties. Glucose is well over normal, indicating that insulin is not enough. BUN, which stands for blood urea nitrogen is the result of protein breaking down. It is clear that after being in the hospital and under care it has dropped from 29 to 21. Begbi, Barber, Reddy, and Simpson (2010) discuss the correlation of HbA1c which correlates to high glucose and this is represented in the patient. Good measures of HbA1c are below 7%, but the patient’ ...Download file to see next pagesRead More

Enhanced nonenzymatic glycosylation of tissue proteins due to persistent exposure to high glucose concentrations and the accumulation of larger quantities of sorbitol (a reduced product of glucose) in tissues are believed to be causative in the pathological changes of diabetes.

Diabetes Case Study of Angelo Reyes in the Neighborhood
Diabetes Case Study of Angelo Reyes in the Neighborhood Introduction Understanding diabetes is not easy. A lot of questions are emerging to the patient themselves or to the family members. Fear arises from lack of understanding of the nature of the disease and finding the answers to these questions as well as supplementing the family with the right knowledge is the first step to manage the long-term complications of diabetes.

Care of the Child with Diabetes Mellitus Type 2 (DM2)
It is further explained by Dea et al. (2011) that initially obesity causes insulin resistance and it is the same that advances into DM2 (p.42). The procedure delineated by the American Academy of Pediatrics and American Diabetes Association has been explained in this article by referring to the screening of children conducted for obesity as a potential risk related to type 2 diabetes (Dea et al., 2011, p.44).

Living with Diabetes
She lives in poor quality accommodation within the inner city. Elizabeth is has diabetes mellitus, which is a condition in which the amount of glucose (sugar) in the blood is too high because the body cannot use it properly. Glucose comes from the digestion of starchy foods such as bread, rice, potatoes, yams and plantain, from sugar and other sweet foods, and from the liver, which makes glucose.

Case Study: A patient with type 2 diabetes
When he first had a fasting blood sugar at that first appointment it was 110 and his blood pressure at the time was normal though his cholesterol and triglycerides were up some. He was placed on a low cholesterol, 1800 calorie ADA diet and routine exercise program but over the last two years he has gained weight.
