Ketone bodies are usually absent in urine. The presence of ketones in the urine probably indicates that the body is using fats rather than carbohydrates for energy. High levels of ketones may be present in the urine of individuals with uncontrolled diabetes because the body's ability to metabolize carbohydrates is defective. Detecting the presence of ketones in the urine is a valuable aid to managing and monitoring individuals with diabetes mellitus. Ketonuria is an indication that the insulin dose needs to be increased. Electrolyte imbalance and dehydration occur when ketones accumulate in the blood. If these conditions are not corrected by adjusting the dose of insulin, the patient may develop ketoacidosis and ultimately diabetic coma. Low levels of ketones may be detected during conditions of physiological stress such as fasting, rapid weight loss, frequent strenuous exercise or prolonged vomiting. The presence of ketones in these situations is due to either inadequate intake of carbohydrates or increased loss of carbohydrates.

Newfield RS. Vargas I. Huma Z.: Eikenella corrodens infections. Case report in two adolescent females with IDDM. Diabetes Care. 19:1011-3, 1996OBJECTIVE: To alert physicians caring for patients with diabetes to the microorganism Eikenella corrodens and to discuss the appropriate preventive and therapeutic measures to take against this potentially morbid opportunistic Gram-negative bacilli.CASES: We present two cases of extra-oral E. corrodens infections in adolescent females with IDDM. The first patient had diabetes of 4 years' duration, which was moderately well controlled. Chronic finger biting resulted in a complex felon that evolved gradually and worsened while the patient received cephalexin orally. Delay in seeking further intervention resulted in necrosis of her distal fingertip and nail bed. The second patient had poorly controlled diabetes for 5 years. She developed an acute thigh abscess at an insulin injection site that resolved after drainage and intravenous antibiotics.CONCLUSIONS: E. corrodens commonly inhabits the human oral cavity and becomes a pathogen mostly when host defenses are impaired, causing abscesses and infections that are at times fatal. Patients with IDDM are compromised hosts and with daily microtrauma to their skin via glucose monitoring and insulin injections, are prone to develop E. corrodens infections that can be introduced through oral secretions by licking or biting their skin. Educational efforts aimed at preventing exposure of traumatized skin to oral secretions can minimize the risk of E. corrodens infections in compromised hosts.Early intravenous administration of antibiotics, bearing in mind E. corrodens resistance to clindamycin, metronidazole, and other antibiotics, coupled with prompt surgical intervention, is essential in successfully managing E. corrodens infections.

When LDL is resolved with electrophoresis, it reveals several subfractions. These subfractions are simply different size populations of LDL particles. Age, gender and lipid status can all affect the LDL subfractionation profile. Individuals who have less dense (so called 'buoyant') LDL have most of their LDL in subfractions 1 and 2. These results are referred to as pattern or phenotype "A" and are normal. Those with significant amounts of subfractions 3- 7 (more dense particles) are at higher cardiovascular risk. These patients have pattern or phenotype "B". The B pattern rarely occurs as an isolated disorder. It is usually accompanied by characteristics of the metabolic syndrome: hypertriglyceridemia, reduced HDL-C , abdominal obesity, insulin resistance, etc.

A technologist performs a venipuncture for glucose testing on the wrong patient. This medical error leads to the patient receiving an incorrect dose of insulin and the patient goes into a coma--this medical error led to an adverse event. Analysis without RCA: Determines the technologist should have checked the patient's wristband (the immediate reaction). Questions why the technologist did not also verbally identify the patient (the subsequent reaction). Restates these reactions (in the internal follow-up review). Misses causes discoverable by a detailed and open investigation.Analysis with RCA: Includes descriptions of events leading up to a "wrong person procedure" in its reports. Describes 17 separate errors identified in the follow-up investigation. Recommends actions that should avoid reoccurrence of the error.
