Urgent Multidetector Computed Tomography in Colon Cancer: Postsurgical Changes and Early Complications.

Complications after surgery for colorectal cancer are common in emergency departments. Multidetector computed tomography plays a fundamental role in the follow-up of patients after surgery, because it enables the detection of relapse and complications. Radiologists need to be familiar with different surgical techniques and the normal postsurgical changes so that we can differentiate them from potential complications and relapse.

[Intensive care unit profesionals's knowledge about non invasive ventilation comparative analysis].

Aims: The literature highlights the lack of noninvasive ventilation (NIV) protocols and the variability of the knowledge of NIV between intensive care units (ICU) and hospitals, so we want to compare NIV nurses's Knowledge from 4 multipurpose ICU and one surgical ICU.

Methods: Multicenter, crosscutting, descriptive study in three university hospitals. The survey instrument was validated in a pilot test, and the calculated Kappa index was 0.

Need for sedation and analgesia in patients with a history of substance misuse admitted to an intensive care unit.

Background: Patients with a history of substance misuse may develop tolerance to analgesics and psychotropic drugs which alter the need for sedation and analgesia after ICU admittance.

Aims: The objective was to qualify and quantify the needs for sedation and analgesia in critically ill patients with and without a history of substance misuse admitted to an intensive care unit (ICU).

Design: A 2-year prospective, observational study.

[Retroperitoneal mucinous cystadenocarcinoma presenting seven years after appendectomy and right hemicolectomy].

Retroperitoneal mucinous cystadenocarcinoma (RMC) with no involvement of neighboring structures is very rare, regardless of whether the lesion is primary or secondary. We report the case of a patient who presented RMC seven years after appendectomy and right hemicolectomy. We discuss both diagnostic possibilities.
