If the infection fails to respond, rem oval of the catheter is indicated. This patient had several bouts of peritonitis during the course of her treatment on peritoneal dialysis. Abdominal computed tom ography revealed a hom ogeneous m ass filling the anterior peri- toneum. At laparotom y the m esentery was encased in a “m arble- like” fibrotic m ass. The patient required long-term hom e parenteral hyperalim entation for recovery. Pericardial tam ponade m ay present as dialysis-induced pericardial friction rub suggest pericarditis (a frequent hypotension.

Earlier, it was attributed to deposition of calcium and raphy dem onstrates cystic disease in this patient, who had focal phosphorus in the skin. Today, we know that is the result of segm ental glom erulosclerosis com plicated by protein C deficiency repeated traum a to the skin associated with scratching. Eleven years after the initial diagnosis, he developed renal failure requiring hem odialysis. Two years after starting dialysis, he developed hem aturia, and these cysts were found. The appearance and clinical course are consistent with acquired cystic disease of the kidney. These cysts carry som e risk of m alignant transform ation. M alnutrition is an important risk factor for dialysis patients, as reflected in this graph depicting the relation of death to serum albumin values.

Yet funding was not signifcantly cut: on clinical trials that it has become difcult to track aggregate, public funding remained more or less and assimilate the huge volume of information.

The share of co-authorships in Brazil and India has been low and is growing slowly; in China they have been low but are growing quickly (4). A 26-country survey of health the results are becoming freely available through systems research found that the number of inves- “open access” arrangements that give unre- tigations increased over the past decade, and that stricted access via the Internet to peer-reviewed decisions about health policy were based on evi- journal articles (part F of Fig. In the dence in about two thirds of the sampled coun- same spirit, the HINARI Access to Research in tries (Chapter 4) (42).

Environmental health research, “health in all”, and universal health coverage Roughly one quarter of the global burden of disease can be attributed to modifiable environmental risk factors (46). This is an approximate estimate because our understanding of the links between our environment and health, and of how to mitigate the risks to health, is far from complete. Further research therefore needs to cover a wide range of investigations from the evaluation of risks associated with environmental exposures, through mechanisms for prevention, to ways of incorporating these measures into the delivery of services (Box 2. The solutions that reduce environmental health risks will come from both within the health sector and beyond it. Environmental risk factors are physical, chemical and biological hazards that directly affect health, and also fac- tors that exacerbate unhealthy behaviours (e. Environmental risk factors include unsafe drinking-water and poor sanitation and hygiene, which are the sources of infections that cause diarrhoeal diseases.
