Navigating Identity: The Intersection of Social and Biological Identity from the World War II Battle of Tarawa.

The 1943 Battle of Tarawa resulted in the loss of approximately 1,000 US service members on or around Betio Island, Tarawa Atoll, Republic of Kiribati. Nearly half these casualties were accounted for after the battle. The Defense POW/MIA Accounting Agency (DPAA) has worked to identify the remaining ∼510 unaccounted-for service members and has successfully identified ∼160 service members to date.

Flow characteristics of peripherally inserted central catheters.

Purpose: Clinical applications of peripherally inserted central catheters (PICCs) are limited by the relatively small lumina and long lengths of these devices. Quantitative analysis of the flow capabilities of a variety of PICCs was performed to aid in deciding which patients should have a PICC and in selecting the appropriate catheter.

Materials And Methods: Sixteen different PICCs from six manufacturers were infused at flow rates of 25-270 mL/h.

Percutaneous transluminal angioplasty of visceral arterial stenoses: results and long-term clinical follow-up.

Purpose: To determine the efficacy and safety of percutaneous transluminal angioplasty (PTA) of the visceral arteries.

Patients And Methods: We retrospectively evaluated the results of PTA performed in 20 visceral arteries in 19 patients (10 men, nine women; mean age, 63 years). Eleven patients had symptoms characteristic of mesenteric ischemia, four had atypical abdominal pain, and four were undergoing prophylactic dilation before undergoing another procedure involving the abdominal aorta.

Contemporary diagnostic approaches to acute pulmonary emboli.

Because of its availability and familiarity, the V/Q scan remains the most frequently used noninvasive screening study for the diagnosis of acute PE. Fast CT and MR imaging techniques probably will have more significant roles in the future in the diagnosis and management of PE, but limited availability and familiarity with these imaging modalities make it impractical to currently recommend them as primary screening tools for acute PE. Although the cost and time benefits appear to place fast CT ahead of MR imaging, more clinical experience and a greater understanding of the imaging nuances and pitfalls of interpretation for both fast CT and MR imaging are needed.
