Primary Sjögren's syndrome is an autoimmune disease that presents with xerostomia and keratoconjunctivitis sicca (due to chronic lymphocytic inflammation of the salivary and lacrimal glands) and in some cases extraglandular features. Patients typically have positive antinuclear, anti-Ro, and anti-La antibodies; however, around 20% to 30% do not and are therefore termed seronegative. We present a case of a 58-year-old woman who was originally diagnosed with seronegative Sjögren's syndrome based on the American-European classification system.

Background: Nonmelanoma skin cancer (NMSC) and associated premalignant lesions represent a major complication after transplantation, particularly in areas with high ultraviolet radiation (UVR) exposure. The American Society of Transplantation has proposed annual NMSC screening for all renal transplant recipients. The aim of this study was to develop a predictive index (PI) that could be used in targeted screening.

Nonmelanoma skin cancer (NMSC) causes significant morbidity and mortality posttransplantation. We examined the annual incidence of NMSC in U.K.

Background: One previous study has shown a higher prevalence of sebaceous hyperplasia (SH) in patients with heart transplant on immunosuppressive drugs as compared with sex-matched control patients.

Objective: We set out to compare the prevalence of SH in a cohort of patients undergoing renal transplant with age- and sex-matched control patients and to find any association with nonmelanoma skin cancer (NMSC) in these patients.

Methods: In all, 117 patients with renal transplant and 117 age- and sex-matched control patients were screened for the prevalence of SH and NMSC.

Caucasian renal transplant recipients from Queensland, Australia have the highest non-melanoma skin cancer (NMSC) risk worldwide. Although ultraviolet light (UVR) exposure is critical, genetic factors also appear important. We and others have shown that polymorphism in the glutathione S-transferases (GST) is associated with NMSC in UK recipients.

Background: Caucasian renal transplant recipients living in Queensland, Australia, have the highest risk of nonmelanoma skin cancer in the world.

Objective: To determine clinical and environmental factors associated with posttransplantation nonmelanoma skin cancer in Queensland.

Methods: 361 Caucasian adult recipients completed a structured interview and full skin examination.

Background: Nonmelanoma skin cancer (NMSC) is a significant clinical problem after renal transplantation, particularly in areas of high UV light exposure. A single-center prospective study of a population of Queensland renal transplant recipients was performed with the aims of: (1) establishing NMSC incidence and tumor accrual post-renal transplantation, and (2) developing a clinically derived predictive index to identify transplant recipients at greatest risk.

Methods: Three hundred ten of 398 transplant recipients (78%) who underwent baseline assessment between July 1999 and April 2000 were reassessed a mean of 18 +/- 3.

Renal transplant recipients are at high risk for multiple non-melanoma skin cancers (NMSC) that occur at a younger age and behave more aggressively. Consequently, the American Society of Transplantation has recommended that physicians conduct annual screenings for NMSC in this population. Few centres currently offer a dedicated surveillance programme.

Acute rejection is a major cause of reduced survival of renal allografts. Vascular endothelial growth factor (VEGF) is a mitogen for endothelial cells and is expressed widely by renal tissue and T cells. VEGF influences adhesion and migration of leukocytes across the endothelium.
