To investigate the relationship between somatosensory evoked potential (SSEP) amplitudes and neurologic outcome after cardiac arrest. ⋯ The prognostic value of SSEPs extends beyond an absent/present dichotomy. Absent and very low amplitude SSEPs appear to be highly predictive of poor outcome after cardiac arrest. Prospective external validation of the lower threshold found in our study is necessary. SSEP recordings should not be used for prognostication if noise could mask potentials with critically low amplitudes. High SSEP amplitudes argue against severe hypoxic encephalopathy.

Anatomic orientation in transsphenoidal surgery can be difficult, and residual tumors are common. A major limitation of both direct microscopy and endoscopic visualization is the inability to see below the surface of the surgical field to confirm the location of vessels, nerves, tumor remnants, and normal pituitary tissue. ⋯ We found the images from our custom-designed ultrasound probe to be clinically helpful for anatomic orientation during surgery, and the technology is potentially helpful for improving the extent of resection during transsphenoidal surgery. This quick and flexible form of intraoperative imaging in transsphenoidal surgery could be of great support for surgeons in both routine use and difficult cases. The concept of transsellar intraoperative ultrasound imaging can be further refined and developed.

The aim of this study was to determine whether the volatile organic compounds (VOCs) pattern in colorectal cancer (CRC) patients is modified by curative surgery for a potential application in the oncologic follow-up. ⋯ Exhaled VOCs pattern from CRC patients is modified by cancer removal confirming the tight relationship between tumor metabolism and exhaled VOCs. PNN analysis provides a high discriminatory tool to identify patients disease-free after curative surgery suggesting potential implications in CRC screening and secondary prevention.

Comparative Study
Cost Comparison of Surgical and Endovascular Treatment of Unruptured Giant Intracranial Aneurysms.
Giant intracranial aneurysms (GIAs), which are defined as intracranial aneurysms (IAs) with a diameter of ≥25 mm, are most likely associated with the highest treatment costs of all IAs. However, the treatment costs of unruptured GIAs have so far not been reported. ⋯ Endovascular GIA treatment produced higher direct costs than surgical GIA treatment mainly due to higher implant costs. Reducing endovascular implant costs may be the most effective tool to decrease direct costs of GIA treatment.

ReviewMassive transfusion: red blood cell to plasma and platelet unit ratios for resuscitation of massive hemorrhage.
The aim of this short study is to review recently published data bearing on how to resuscitate massive uncontrolled hemorrhage. ⋯ The bulk of currently available data support the use of a 1 : 1 : 1 ratio for the resuscitation of patients with severe injury, shock, and uncontrolled hemorrhage. The application of this formulaic approach to massive blood product-based resuscitation in other clinical situations is less well supported in the literature.
