Reductions of Plastic Microbeads from Personal Care Products in Wastewater Effluents and Lake Waters Following Regulatory Actions.

Plastic microbeads were widely used as exfoliants in personal care products (PCPs; e.g., hand/body washes) in North America, but restrictions were imposed on their use in PCPs in the U.

An unusual case of herniation of small bowel through an iatrogenic defect of the falciform ligament.

Internal herniation through a congenital defect in the falciform ligament is extremely rare. We report an unusual observation of small bowel obstruction through an iatrogenic defect of the falciform ligament. Prompt diagnosis was made by helical CT, permitting a rapid surgical procedure to preserve the viability of the obstructed segment.

[Multilocular cystic nephroma in adults. Unusual presentation and review of the literature].

The authors report a case of a multilocular cystic nephroma in an unusual site, extensively invading the pelvis and causing atypical symptoms of acute lumbar pain. The authors discuss the confusing terminology, the unusual presentation of this cystic tumour and the difficulty of establishing a definitive diagnosis of its benign nature before the operation in the light of a brief review of the literature.

[Comparison of spiral computed tomography without contrast media and intravenous urography in the diagnosis of renal colic].

Objectives: This prospective study was designed to determine the reliability of noncontrast spiral CT scan, compared to that of intravenous urography (IVU), in the diagnostic assessment of acute renal colic.

Material And Methods: 53 patients, admitted with an empirical diagnosis of renal colic after initial assessment, were included and underwent spiral CT scan without contrast agent injection, immediately followed by IVU. These examinations were performed according to a blind protocol by two different radiologists.

Radiologic investigation of renal colic: unenhanced helical CT compared with excretory urography.

Objective: Our aim was to compare unenhanced helical CT and excretory urography in the assessment of patients with renal colic.

Subjects And Methods: Fifty-three of 70 consecutive patients with acute signs of renal colic were prospectively examined with unenhanced helical CT, which was followed immediately by excretory urography. Two radiologists who were unaware of the findings independently interpreted these examinations to determine the presence or absence of ureteral obstruction.
