The impact of chlorhexidine bathing on hospital-acquired bloodstream infections: a systematic review and meta-analysis.

Background: Chlorhexidine gluconate (CHG) bathing of hospitalized patients may have benefit in reducing hospital-acquired bloodstream infections (HABSIs). However, the magnitude of effect, implementation fidelity, and patient-centered outcomes are unclear. In this meta-analysis, we examined the effect of CHG bathing on prevention of HABSIs and assessed fidelity to implementation of this behavioral intervention.

CT appearances following laparoscopic partial nephrectomy for renal cell carcinoma using a rolled cellulose bolster.

Purpose: To describe the evolving computed tomography (CT) appearances of a cellulose surgical bolster used as a hemostatic agent in patients who undergo laparoscopic partial nephrectomy for renal cell carcinoma.

Materials And Methods: We retrospectively reviewed the follow-up CT studies of 33 patients with stage T1N0M0 renal carcinoma who underwent laparoscopic partial nephrectomy using a rolled, oxidized, regenerated cellulose sheet sutured in place as a bolster in the parenchymal defect. Thirteen patients undergoing laparoscopic partial nephrectomy without the use of a bolster were also evaluated to differentiate imaging features.

Incidentally-discovered adrenal masses.

Unanticipated adrenal masses are frequently encountered in modern, high resolution diagnostic imaging. Most often, these masses are benign adrenal adenomas, but when detected they necessitate a clinical evaluation sufficient to exclude subclinical endocrine disease, primary adrenal cancer, and remote metastases to the adrenal glands from other malignancies. These "incidentally-discovered" adrenal masses or so-called "adrenal incidentalomas" can be further evaluated with CT, MRI, and nuclear medicine imaging techniques.

Lipomatous adrenal metaplasia: computed tomography findings in 2 presumed cases.

We present 2 computed tomography cases of adult asymptomatic patients whose adrenal glands contained nonfocal collections of fat diffusely distributed throughout the limbs. Although no pathological proof is available, this pattern of fat distribution corresponds to a well-described pathological entity, lipomatous adrenal metaplasia.

Excretory urography: trends in clinical use and diagnostic yield.

Objective: To assess for changes in clinical usage and diagnostic yield of excretory urography (EU) following the introduction of CT urography (CTU).

Materials And Methods: We retrospectively reviewed reports from 6313 EUs performed between July 1995 and February 2006. The specialty of the ordering physician and clinical indication for the study were recorded, as were any collecting system, ureter, or bladder abnormalities suspicious for urothelial malignancy identified on EU.
