Objective To describe our experience with hernioplasty in peritoneal dialysis patients and to identify possible risk factors for surgical complications. Design A 4-year retrospective chart review of data. Setting Peritoneal dialysis unit of a university hospital. Patients and Methods 58 hernias in 50 patients were included. Detailed surgical technique and complications were recorded. Possible risk factors included age, gender, weight, height, body mass index, previous surgery, diabetes, time on dialysis, emergency surgery, hospital stay, type of hernia, mesh use, blood hemoglobin, and serum urea, creatinine, and potassium. Results Complications occurred in 12 hernioplasties (4 wound infections, 2 peritonitis, 4 catheter dysfunction, and 5 re-operations). Recurrence rate was 12% without mesh use and 0% with mesh hernioplasty. Dialysis was re-instituted in 96% of cases within 3 days postoperatively. Identified risk factors for complications were diabetes, low weight, low height, small body mass index, and low serum creatinine. Conclusions Mesh hernioplasty in peritoneal dialysis patients is advisable. Postoperative dialysis with low volume is feasible after surgery. Prospective studies will corroborate our risk factors for morbidity.

Seasonal changes in body mass and body composition of ringed seals (Phoca hispida) from the Svalbard Islands are described. The blubber content of adult females decreased from a high of about 50% at the beginning of the pupping season in March–April to a low of 31% during moulting in June. In adult males, the blubber content decreased from 41% in March to 29% in June. By estimating an individual seal's body mass by 1 April from its standard body length, we calculated an average daily loss of body mass of 160 g/day in adult females and 100 g/day in adult males from the start of lactation to the middle of moulting. The blubber content of sexually immature seals was less in June and July than in April, but the seasonal changes were smaller than in adult seals. We found no evidence of significant changes in core mass in adult seals, and suggest that the seasonal body mass changes are mostly due to changes in body fat content.

The coastal and offshore waters of Southwest Greenland are internationally important winter quarters for seabirds. We crudely estimate a minimum of 3.5 million seabirds using the region in winter, mainly from Arctic Canada, Greenland and Svalbard, with smaller numbers also from Alaska, Iceland, mainland Norway and Russia. The most numerous species are Common Eider Somateria mollissima, King Eider S. spectabilis, Brünnich's Guillemot Uria lomvia and Little Auk Alle alle. The most immediate threat to the seabirds in Southwest Greenland is hunting, and current levels of usage of the Greenland breeding populations of Brünnich's Guillemot and Common Eider are considered unsustainable. Conservation measures are required for these populations.
