| False Positive Ketone Results False positive ketone results may be seen in patients after BSP or PSP dye injection due to the phthaleins. The presence of L-DOPA metabolites, some urine preservatives (e.g. 8-hydroxyquinaline), or high levels of phenylketones will also cause false positive results. Antihypertensive drugs such as methyldopa and captopril also may produce false positive results. | View Page |

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. | View Page |

| The Hepatitis B Vaccination The Hepatitis B Vaccine is one of the most important ways to prevent infection. About 90% of people who receive it get immunity.The present recombinant vaccine is made by genetically altered bakers yeast and contains no blood components. It is very safe.Side effects are minimal. Symptoms such as temporary soreness at the injection site, mild fever, or joint pain may occur but are rare.The procedure consists of three shots in the upper arm given over a six month period.The OSHA standard requires that employers provide the vaccine free of charge to you if your occupation puts you at risk. You may decline the vaccine; but you will be asked to sign a Declination Statement. | View Page |
| A physician needs to prescribe a drug with a narrow therapeutic window. He is concerned about possible toxic effects. To assess the upper concentration of such a drug, which time for drawing the specimen do you think makes the most sense? | View Page |
| Peak and Trough Sampling Times To assess drug concentrations during the trough phase, blood should be drawn immediately before the next dose. To assess peak levels, the time for drawing depends on the route of administration: Oral: One hour after drug is taken (assumes a half-life of > two hours) IV: 15-30 minutes after injection/infusion Intramuscular (IM): 30 minutes - one hour after injection | View Page |
| Syringes with built-in safety devices Syringes are used for injections, as well as to collect blood.
There a various syringes with built-in safety features.One example is the Monoject™ (Sherwood Services AG), Safety Syringe, shown here. | View Page |
| Another Echinocyte Another example of an echinocyte is seen in the center of this slide. In rare instances, echinocytes circulate in vivo in uremia, following heparin injection, in certain congenital anemias and in pyruvate kinase deficiency. Plastic slides must be used to verify the presence of in vivo echinocytes. Since echinocytes do not aid in the diagnosis of these conditions, their main importance lies in the fact that they are artifactual and reversible and must be distinguished from acanthocytes. | View Page |
| Records and Results Skin tests are read 48-72 hours after injection by a trained health-care worker such as a physician or nurse.The diameter of any induration is measured in millimeters.Records of the test are kept in the individual's health record for future reference. | View Page |
