Aims-To describe features influencing the management of primary iris melanoma and report the outcome of conservative surgical treatment of patients diagnosed with this condition in a tertiary referral academic setting over a 20 year period. Methods-Retrospective non-comparative case series of consecutive patients diagnosed with iris melanoma from 1980-2000 using medical records from the University of Sydney Department of Ophthalmology and NSW Cancer Registry Results-51 cases were identified. The most common presentation was growth of a previously noted pigmented lesion. Initial management was either observation or local resection (two had enucleations) with iris reconstruction where possible (23.8%). The mean follow up was 8.7 years (range 1-17 years). Vision of 6/12 or better was maintained in the majority (78.6%) treated by local resection. Pupil reconstruction significantly reduced reported postoperative glare symptoms. Four patients had features suggestive of local recurrence and there was no documented metastatic disease or death from iris melanoma in this series. Histologically, the majority were spindle B cell melanomas. Clinical features including prominent tumour vascularity, rapid growth, and heterogeneous pigmentation were each significantly associated with an epithelioid cell component. Involvement of the iridocorneal angle was frequently associated with ciliary body invasion. Conclusions-Management decisions for iris melanoma will depend on the clinical features. Mixed or epithelioid histology is more likely in the presence of two or more of the features of malignancy and may justify earlier intervention. When treatment is undertaken, local resection achieves long term tumour clearance with an acceptable morbidity. In resecting iris melanoma, careful assessment for iridocorneal angle involvement is important in treatment planning. Iris reconstruction has a useful role in reducing postoperative photophobia.

Introduction: We investigated the differences between prostate cancer patients with radiation-induced hematuria treated with hyperbaric oxygen (HBO) therapy that did or did not have a resolution of hematuria. Materials and Methods: We performed a retrospective review of prostate cancer patients with radiation-induced hematuria who underwent HBO from April 2000 to March 2010. We performed an analysis of demographic data and severity of hematuria in those who had resolution of or persistent hematuria. Additionally, prostate-specific antigen (PSA) data were also obtained during the study period. Results: Overall, 11/22 men had resolution of hematuria after HBO therapy with a median follow-up of 2.2 (0.35-13.6) years. The Radiation Therapy Oncology Group (RTOG) grade of hematuria is predictive of final hematuria outcome (resolution vs. persistent) after HBO (p = 0.026). No significant PSA changes were noted before and after HBO therapy. Conclusions: The RTOG hematuria grade is associated with the resolution of hematuria after HBO therapy for radiation-induced hematuria in men treated for prostate cancer. This information may be helpful during shared medical decision-making regarding utility of HBO therapy in the context of severity of hematuria.
Goodpasture’s disease is an uncommon composite of features including renal failure with pulmonary hemorrhage secondary to an autoimmune response that specifically targets these organ systems. We present a case of particular interest in regards to atypical presentation, and the uncommon treatment that the patient underwent. A 65-year-old Afghani female arrived with complaints of nausea, vomiting, loss of appetite, malaise, decreased urine output, exertional dyspnea, and cough. The patient presented initially with renal failure and unexpectedly developed respiratory failure after hemodialysis. Initial CT of thorax revealed diffuse bilateral pulmonary edema. Subsequently, the patient received a bronchoscopy demonstrating alveolar hemorrhage, which highlights a clinician’s need to maintain a differential and reassess patients. Anti-GBM antibody in the serum was detected and the renal biopsy revealed evidence of the antibody on immunofluorescence. In regards to management, the patient could only be treated with plasmapheresis as she had contraindication to initiation of immunosuppression, after which she showed significant clinical improvement. We would like to highlight the benefit of plasmapheresis without concomitant immunosuppression and recommend such an approach to be considered in similar clinical scenarios, where contraindication for immunosuppressant therapy exists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
