BACKGROUND Photopheresis is an immunomodulatory therapy for the treatment of T cell-mediated disorders. It has been used for rejection prophylaxis in cardiac transplantation, adjuvant treatment of bronchiolitis obliterans in lung transplantation, treatment of graft verse host disease, and in a small number of cases, for treatment of acute rejection in renal(More)
Preeclampsia is a complication of pregnancy with significant morbidity and mortality for the mother and the fetus. Presumptions are made that placental hypoxia has a causative role in the clinical syndrome. Furthermore, soluble fms-like tyrosine kinase 1 (sFLT-1) has been shown to have a role in the maternal syndrome of preeclampsia. We investigated the(More)
Fine-needle biopsy (FNB) has been reported as a rapid, minimally invasive technique for the diagnosis of metastatic melanoma. The diagnostic accuracy of FNB was assessed in a consecutive series of 2,204 FNBs of clinically suspicious lesions from patients with previous primary melanomas treated at the Sydney Melanoma Unit, Sydney, Australia, between January(More)
Desmoplastic melanoma (DM) is a rare subtype of melanoma characterized by malignant spindle cells associated with prominent fibrocollagenous stroma. Primary melanomas may be entirely desmoplastic ("pure" DM) or exhibit a desmoplastic component admixed with a nondesmoplastic component ("combined" DM). The cytologic features of only 5 cases of DM have been(More)
BACKGROUND This is a review of a series of patients who presented with thymoma over the most recent 20-year period. Changes and trends in disease patterns were documented. METHODS Data were collated retrospectively but all pathology slides were reviewed. Survival functions were estimated using the Kaplan-Meier method. RESULTS Seventy-one patients had a(More)
Preeclampsia is a common disease of pregnancy characterised by maternal hypertension and proteinuria. Abnormal placentation in early pregnancy and abnormal cytokine and anti-angiogenic factor expression are thought to contribute to the clinical syndrome of endothelial dysfunction evident in the second half of gestation. The mechanisms underlying both the(More)
BACKGROUND The use of fine needle biopsy (FNB) for the diagnosis of metastatic melanoma can lead to the early removal and treatment of metastases, reduce the frequency of unnecessary surgery, and facilitate the staging of patients enrolled in clinical trials of adjuvant therapies. In this study, the accuracy of FNB for the diagnosis of metastatic melanoma(More)
Adenosquamous carcinoma of the cervix is rare. It is defined as having both glandular and squamous cell differentiation, each component malignant and clearly seen on haematoxylin and eosin-stained slides alone. We report two cases of adenosquamous carcinoma of the uterine cervix, both of which showed in situ and invasive components and both of which showed(More)
