Thrombolysis as a treatment for transplant renal artery thrombosis - a report of three unsuccessful cases and an overview of reported cases.

Introduction: Thrombolysis has been suggested as a feasible method to treat arterial renal transplant thrombosis under conditions of short duration of ischemia. Data on maximal duration of ischemia that are still feasible to treat are scarce.

Methods: We retrospectively analysed our experience involving three attempts to utilize thrombolysis to treat transplant renal artery thrombosis.

Combined study of source, environmental monitoring and fate of branched alkylphenols: The chain length matters.

Alkylphenols (APs) are chemicals of largely anthropogenic origin. Longer chain derivatives like 4-nonylphenol (4NP) or 4-tert.-octylphenol (4tOP) are mainly used for the production of alkylphenol ethoxylates, while short chain alkylphenols (SCAPs) can be applied during the production of phenolic or epoxide resins that are used in paint, glue or adhesive formulations.

Previously unidentified sources of perfluoroalkyl and polyfluoroalkyl substances from building materials and industrial fabrics.

Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are applied during the production of various consumer and industrial goods. As a consequence of their use in building materials and fabrics, unreacted nonpolymeric PFASs might enter the environment by evaporation or urban run-off. Since the PFAS content of building materials and industrial fabrics is hardly investigated, studies have to be performed in order to assess their total PFAS load.

Risk of recurrence of primary sclerosing cholangitis after liver transplantation is associated with inflammatory bowel disease.

Aim: To evaluate risk factors for primary sclerosing cholangitis (PSC) recurrence (rPSC) after orthotopic liver transplantation (OLT) in patients with well-preserved colons.

Methods: We retrospectively evaluated the medical records of all patients transplanted for PSC in our center between July 1994 and May 2015 and selected 47 with follow-up of at least 60 mo for further analysis based on strict inclusion and exclusion criteria. rPSC was confirmed by magnetic resonance or endoscopic retrograde cholangiopancreatography and liver biopsy.
