A new phosphate-selective sorbent for the Rem Nut process. Laboratory investigation and field experience at a medium size wastewater treatment plant.

P-control technologies for municipal wastewater are essentially based on "destructive" methods, that lead to formation of concentrated solid-phases (sludge), usually disposed-off in controlled landfills. Ion exchange, as a "non-destructive" technology, allows for selective removal and simultaneous recovery of pollutants, which can be recycled to the same and/or related productive lines. In this context, the REM NUT process removes nutrient species (HPO4 = , NH4+, K+) present in biologically oxidised municipal effluents and recovers them in the form of struvites (MgNH4PO4; MgKPO4), premium quality slow release fertilisers. The main limitation to the extensive application of this ion exchange based process is the non-availability of selective exchangers for specific removal of nutrient species. This paper illustrates laboratory investigation and pilot scale development of a so-called "P-driven" modified REM NUT scheme based on a new phosphate-selective sorbent developed at Lehigh University, PA, USA.

Seatbelt injury to the common iliac artery: case report.

In traffic accident victims, the seat belt syndrome is a well known injury which rarely involves the common iliac artery due to its posterior anatomical position and to protection by the pelvis. We report a case of blunt abdominal trauma related to the type of seat belt worn. The trauma provoked subintimal haemorrhaging of the left common iliac artery, without skeletal lesions or other visceral injuries. Correct diagnosis was delayed for three months after the crash, when an angiogram was performed to investigate disabling claudication and vascular pulse change in the left leg. This arterial injury could have been related to the association of two different types of force created during the crash ("compression/deceleration-type mechanism") that might have produced shearing forces causing a vascular wall discontinuity and/or an intimal flap. The authors speculate that the vascular lesion was observed on the same (left) side as the fastening point of the seat belt (a lap-and-shoulder belt with a three-point attachment) where the shearing forces may have been most intense due to the junction between the lap strap and the diagonal shoulder belt.

Liver inflammation and acute respiratory distress syndrome in a patient receiving hepatitis B vaccine: a possible relationship?

We describe a patient in whom clinical evidence of liver and lung dysfunction developed after he received the second dose of recombinant hepatitis B vaccine, despite no serologic evidence of viral hepatitis. However, liver biopsy specimens demonstrated both surface antigens and core antigens, possibly indicating silent hepatitis B virus infection. A search for an infective etiology for the patient's subsequent clinical deterioration in lung function did not yield pathogens: postmortem examination revealed evidence of immune complex-mediated organ injury in the liver, lungs, and kidneys.

Living donor kidney transplant: medicolegal and insurance aspects.

Kidney transplantation is quite a routine complex procedure, not without risks and consequences to the donor, the recipient, and the health care professionals. Kidney-related medical malpractice suits are growing rapidly, and for clinicians and surgeons, the risk of being sued can be only reduced by practicing high-quality medicine and by appropriately communicating with donors and recipients. Actually relevant guidelines are available including safety and quality assurance standards for procurements, preservation, processing, and distribution for organs to maximize their quality and thereby the rate of success of transplants and to minimize the risk of such a procedure. We also find it essential that practice of living donor kidney transplant is in line with the general rules of the Convention for the Protection of Human Rights and its Additional Protocol. In this article, financial incentives and insurance aspects related with living donors kidney transplants are also illustrated.
