The incidence, survival, and blood product use after emergency department thoracotomy (EDT) in combat casualties is unknown. ⋯ In the combat casualty with penetrating injury, arriving with signs of life, receiving CPR, and undergoing EDT, longterm survival with normal neurologic outcomes is possible. CPR is not a contraindication to performance of EDT in penetrating injuries if signs of life are present. A large amount of blood products are used in the resuscitation of EDT patients.

Comparative Study
Intraperitoneal gas insufflation will be required for laparoscopic visualization in space: a comparison of laparoscopic techniques in weightlessness.
Laparoscopic surgery (LS) is contemplated during long duration space flight, but it typically necessitates intraabdominal hypertension (IAH) from insufflation to create a surgical domain. Because there are spontaneous changes in abdominal wall behavior in weightlessness (0g) that have been previously suggested to increase LS visualization, we studied the comparative laparoscopic visualization between gasless (noGAS), abdominal wall retraction (AWR), and standard 15 mmHg gas insufflation (GAS) during weightlessness. ⋯ Both noGAS and AWR are impractical in weightlessness. Gas insufflation will be required. With insufflation, visualization and perceived ability to perform LS was improved by weightlessness.

Gastric electrical stimulation in intractable nausea and vomiting: assessment of predictive factors of favorable outcomes.
Gastric electrical stimulation (GES) represents a new therapy in patients with intractable vomiting and nausea. We aimed to determine preoperative factors associated with positive response during GES. Thirty-three consecutive patients received implants for medically refractory nausea or vomiting or both. ⋯ Patients with severe symptoms and altered QOL at inclusion particularly benefit from GES; delay in GE is not predictive of positive outcomes. This suggests that indication for GES should be based on clinical settings rather than initial GE, and then possibly extended to patients with normal GE.

The benefit of breast MRI for newly diagnosed breast cancer patients is uncertain. This study characterizes those receiving MRI versus those who did not, and reports on their short-term surgical outcomes, including time to operation, margin status, and mastectomy rate. ⋯ Breast MRI use was not confined to any particular patient group. MRI use was not associated with improved margin status or BCT attempts, but was associated with a treatment delay and increased mastectomy rate. Without evidence of improved oncologic outcomes as a result, our study does not support the routine use of MRI to select patients or facilitate the performance of BCT.
