Encapsulating peritoneal sclerosis: experience of a tertiary referral center.

AIM: Encapsulating peritoneal sclerosis (EPS) is arguably the most serious complication of chronic peritoneal dialysis (PD) therapy with extremely high mortality rates. We aimed to establish the rates of EPS and factors associated with its development in a single center. METHODS: We retrospectively reviewed the records of all our PD patients from 1 January 1989 until 31 December 2008. All suspected cases were confirmed at laparotomy. Multifactorial models adjusted for potentially confounding variables such as age and sex. RESULTS: Eleven cases of EPS were identified giving a prevalence rate of 1.98%. Median duration on PD was substantially longer in affected versus unaffected patients (42.5 months versus 13.8 months; p = 0.0002). EPS patients had experienced a mean of 3.54 previous cases of peritonitis (1 infection per year versus 0.71 per year in unaffected patients; p = 0.075). Six patients died (54.5%) due to intra-abdominal sepsis including all five who presented with small bowel obstruction. Three patients had an omentectomy and adhesiolysis performed with a successful outcome. CONCLUSION: Our study reinforces the link between duration on PD and EPS. While mortality was high in our cohort, emerging surgical techniques demonstrate a favorable outcome that can be achieved even in severely affected cases.

An assessment of the long-term health outcome of renal transplant recipients in Ireland.

BACKGROUND: Renal transplantation remains the preferred method of renal replacement therapy in terms of patient survival, quality of life and cost. However, patients have a high risk of complications ranging from rejection episodes, infection and cancer, amongst others. AIMS AND METHODS: In this study, we sought to determine the long-term health outcomes and preventive health measures undertaken for the 1,536 living renal transplant patients in Ireland using a self-reported questionnaire. Outcomes were divided into categories, namely, general health information, allograft-related information, immunosuppression-related complications and preventive health measures. RESULTS: The results demonstrate a high rate of cardiovascular, neoplastic and infectious complications in our transplant patients. Moreover, preventive health measures are often not undertaken by patients and lifestyle choices can be poor. CONCLUSIONS: This study highlights the work needed by the transplantation community to improve patient education, adjust immunosuppression where necessary and aggressively manage patient risk factors.

Total hip replacement in sickle cell disease.

We report on 35 total hip replacement arthroplasties in 28 patients with avascular necrosis of the femoral head secondary to sickle cell disease (SCD). There were 15 men and 13 women with a mean age of 27.5 years. In all patients Harris hip scores improved from a mean of 36 pre-operative to 86 post-operative. However, at a mean follow-up of 9.5 (5-15) years six hips failed due to symptomatic aseptic loosening and one due to late deep infection. Our results support the decision to offer the procedure for patients with arthritic hips secondary to SCD. It is important that patients and surgeons should be aware of the wide varieties of complications.

A common HLA phenotype in slipped capital femoral epiphysis?

Studies from three different countries have linked the HLA B12 and DR4 antigens with slipped capital femoral epiphysis (SCFE). We questioned whether our patients shared in common either of these antigens. HLA phenotype was determined in 7 patients with SCFE, two of whom were brothers with almost identical haplotypes. The B12 antigen was found in none of our patients and the DR4 in only 3. Neither of the 2 brothers held the DR4 antigen. The commonest antigens (also shared by the 2 brothers) were B35, present in 5 and DR52 in 4 of 7 patients. We conclude that neither the previously described B12 nor the DR4 antigen can reliably serve as genetic markers for SCFE in our region.
