Choices of Therapeutic Strategies for Colorectal Liver Metastases Among Expert Liver Surgeons: A Throw of the Dice?

Objective: To test the degree of agreement in selecting therapeutic options for patients suffering from colorectal liver metastasis (CRLM) among surgical experts around the globe.

Summary/background: Only few areas in medicine have seen so many novel therapeutic options over the past decades as for liver tumors. Significant variations may therefore exist regarding the choices of treatment, even among experts, which may confuse both the medical community and patients.

Urology mythbusters: do we need to surgically correct vesicoureteral reflux in older girls to prevent problems in future pregnancy? (revision 1).

In this edition of Mythbusters we critically examine the premise that, because women with history of vesicoureteric reflux (VUR) are at higher risk of urinary tract infection (UTI) and other morbidity during pregnancy, persistent VUR in older girls should be considered an indication for surgical correction. The literature is very limited in that there are essentially no methodologically robust comparisons of pregnancy outcomes among women whose childhood VUR was or was not surgically repaired. Most of the case series and cohorts find relatively high incidence of UTI and pyelonephritis among pregnant women with a history of VUR, but there is very little to suggest that persistent VUR is itself a risk factor for infection during pregnancy.

Orofacial granulomatosis and diet therapy: a review of the literature and two clinical cases.

Orofacial granulomatosis is a nonspecific term that contains a wide variety of granulomatous entities, which share a clinical and histopathological presentation. It manifests as persistent or recurrent orofacial swelling, amongst other findings. Idiopathic orofacial granulomatosis, characterized by an absence of systemic granulomatous disease, is a diagnosis of exclusion.

Correspondence between fiber post and drill dimensions for post canal preparation.

Purpose: To compare fiber posts of several calibers and trademarks to their corresponding root canal preparation drills.

Methods: Three widely used endodontic post brands and their drills were evaluated: Exacto, ParaPost Taper Lux, and Macro-Lock Illusion X-RO. Fiber posts and drills were microphotographed with a scanning electron microscope and images were analyzed using ImageJ image processing software.
