Particle-size and radiochemical purity evaluations of filtered 99mTc-sulfur colloid prepared with different heating times.

Unlabelled: Sentinel node lymphoscintigraphy using colloidal particles has become common practice at many institutions. The ideal particle size for colloids such as filtered (99m)Tc-sulfur colloid ((99m)Tc-FSC) in sentinel node studies is 15-100 nm. It is reported that the use of a reduced heating time during the reconstitution process results in an increased number of smaller particles (<30 nm).

The evolution of dependent medical care in the U.S. Army.

There is great focus within the military medical community regarding the ever growing cost of medical care overall and dependent care specifically. A great deal of discussion relates to the delivery of care through a growing military-civilian partnership, where an increased amount of health care will be referred to an ever growing network of civilian providers. The U.

The effects of an accelerated triage and treatment protocol on left without being seen rates and wait times of urgent patients at a military emergency department.

To combat increasing wait times and left without being seen (LWOBS) rates, our emergency department (ED) implemented an accelerated triage and treatment (TNT) protocol. A TNT team was allocated treatment rooms to begin management of urgent patients if a bed in the main ED was not available. A retrospective database study was performed using three separate 6-month periods: two control periods before the intervention (P1, P2) and one period after the intervention (P3).

Trends of radiopharmaceutical use at Mayo Clinic Rochester.

Unlabelled: The field of radiology is continuously changing. The purpose of this study was to identify the effect of technologic advances on nuclear medicine during the past 15 y.

Methods: The number of radiopharmaceutical doses dispensed at Mayo Clinic (Rochester, Minnesota) from 1990 through 2004 was tracked.

Lamotrigine as a possible cause of QRS prolongation in a patient with known seizure disorder.

Lamotrigine and felbamate are 2 newer anticonvulsant medications used to control refractory partial and generalized seizures. Although several cases of lamotrigine toxicity secondary to acute intentional or unintentional overdose have been described, there is little published information related to potential side-effects associated with the therapeutic use of these agents. Described is a case of a 22-year-old woman who presented to the emergency department after experiencing 2 seizure-like episodes.

Recurrent arthralgias in a patient with previous Mayaro fever infection.

Mayaro fever is an acute, self-limited, febrile, mosquito-borne viral disease manifested by fever, chills, headache, myalgias, and arthralgias. The virus belongs to the family Togaviridae and the genus Alphavirus. Five other mosquito-borne viruses have been described as causing a similar dengue-like illness.

Determining the accuracy of a rapid point-of-care test for determining Rh(D) phenotype.

Objectives: To determine the sensitivity, specificity, and accuracy of a point-of-care method for identifying Rh(D) phenotype.

Methods: Rh(D) was determined using preserved whole blood via standard laboratory methods. Comparison testing was conducted using the HealthTEST Rh(D) card (Akers Laboratories, Thorofare, NJ).

Post-traumatic subdural hygroma: case report.

Subdural Hygroma (SDG) is described in the literature as a common complication of blunt head trauma occurring in a reported 5-20% of all closed head injuries. The Emergency Physician will likely encounter this type of lesion and it is useful to have an understanding of its significance, its relationship to subdural hematoma (SDH), and management strategies. Although surgical intervention is often advocated in the treatment of intracranial fluid collections causing mass effect, there are several reported cases of spontaneous resolution of uncal and central herniation via conservative management alone.
