ReviewPatient populations at risk for intra-abdominal hypertension and abdominal compartment syndrome.
Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are critical care conditions with significant morbidity and mortality. The surgical measure to treat ACS (decompressive laparotomy) is hazardous and results in an open abdomen with potential major complications such as fistulas, abscesses, and large ventral hernias. ⋯ Knowledge of the patient populations at high risk for developing IAH/ACS is crucial. The aim of this review is to discuss the high-risk populations for acute IAH/ACS among surgical patients.

Improving mortality predictions in trauma patients undergoing damage control strategies.
The increased use of damage control surgery in complex trauma patients requires accurate prognostic indicators. We compared the discriminatory capacity of commonly used trauma and intensive care unit (ICU) scores, including revised trauma score, injury severity scores, trauma score-injury severity scores, acute physiology and chronic health evaluations II, and clinical and laboratory parameters, on 83 consecutive trauma patients admitted to the ICU, undergoing damage control. Logistic regressions were built for mortality prediction within 30 days. ⋯ This model was adjusted for age and demonstrated better discrimination for mortality prediction (areas under the receiver operating characteristic curve = 0.8054) than injury severity score (P value = 0.049), abdominal trauma index (P value = 0.049), and acute physiology and chronic health evaluations II (P value = 0.001). There was no statistically significant difference in discrimination for mortality prediction between the "clinical" model and revised trauma score (P value = 0.4) and trauma score-injury severity score (P value = 0.4). We concluded that the combination of ICU admission pH and hypothermia and blood transfusions during 24 hours provided an excellent discriminatory capacity for mortality prediction in this complex patient population.

Defining incidence and outcome of contrast-induced nephropathy among trauma: is it overhyped?
Contrast-induced nephropathy (CIN) in trauma patients is uncommon and the incidence is unknown. We studied the incidence of CIN and its outcome. A retrospective chart review of trauma patients 16 years of age and older who were admitted to our Level I trauma center during 2005 was performed. ⋯ All but two serum Cr levels peaked within 48 hours; all returned to baseline. One patient with an underlying congenital kidney disease required temporary dialysis. CIN incidence in trauma is low and the clinical course is benign.

Use of a handheld, semiconductor (cadmium zinc telluride)-based gamma camera in navigation surgery for primary hyperparathyroidism.
The recent development of gamma-ray probes makes it possible to perform radioguided surgery for primary hyperparathyroidism (PHPT). There have only been a few reports, however, regarding the use of a handheld gamma camera to detect parathyroid adenoma intraoperatively. The aim of this preliminary study was to assess the efficiency of a semiconductor gamma camera (eZ-SCOPE AN) in navigation surgery for PHPT. ⋯ Scintigraphy images of the neck by eZ-SCOPE also revealed a single adenoma even before skin incision. Our results suggest that Tc-MIBI scintigraphy with the eZ-SCOPE is useful for navigation surgery for PHPT. The eZ-SCOPE is useful for skin marking and could be easily applied for minimally invasive radioguided parathyroidectomy in scan-positive cases.
