RESUMO
A common situation presented in any clinical facility is a woman with swelling and redness of the breast. Diagnosis upon suspicion is often mastitis or inflammatory breast cancer, which are popular and well-known diseases of the breast. However, there is one main differential diagnosis which has to be taken into consideration: lymphedema of the breast. Twenty patients with internal diseases presented in our Breast Care Unit over a 4-year period with breast-affecting lymphedema. The patients suffered from cardiac failure, nephrotic syndrome, liver failure, lymphadenopathy, and central vein occlusion. Additionally, we identified 5 patients with a history of organ transplantation and under immunosupressive medication with sirolimus or everolimus. These mTor inhibitors are known to have unwanted side effects such as unilateral or bilateral upper/lower extremity peripheral edema or facial/eyelid edema, but as we know, isolated lymphedema of the breast represents a previously unreported complication.

INTRODUCTION: Extravasations of chemotherapeutic drugs may lead to tissue necrosis and subsequent tissue defects, sometimes resulting in loss of function. In the absence of therapy, approximately one-third of vesicant extravasations will result in ulcerations, some of which necessitate plastic microsurgery to cover the soft tissue defects. The aim of this study was to describe the surgical technique itself and to present clinical results of the procedure in a clinical series of chemotherapeutic extravasation injuries that benefitted from a subcutaneous wash-out procedure (SWOP) by minimisation of serious complications. PATIENTS AND METHODS: Over a time period of 3 years, we treated 13 female patients following chemotherapeutic extravasation injury. Nine of the cases involved a high vesicant chemotherapy agent, and four patients involved chemotherapy with low vesicant potential. The therapeutic approach was performed using SWOP exclusively without the application of specific antidotes. RESULTS: The mean time interval between the extravasation injury and the SWOP was 345min (140-795min). In none of the cases was there a tissue breakdown, but there was a steady decrease in the inflammatory reaction of the cutaneous and subcutaneous soft tissues without additional complications over a 3-month follow-up period. CONCLUSION: The results of the study suggest that SWOP is a minimally invasive, safe and effective emergency treatment for chemotherapeutic extravasation injury. Based on the absence of comparative studies with regard to the efficacy of conservative therapy, SWOP should be offered as a therapeutic option for chemotherapeutic extravasations, especially in cases of medical malpractice and also as a defence in case of a legal conflict.

BACKGROUND: Vitreous surgery for Idiopathic macular holes can result in both anatomic closure of the hole and visual improvement. In some patients even normal visual acuity is achieved. Postoperative visual field loss is a newly recognized complication. This prospective study evaluates the frequency and significance of scotomas after vitrectomy with gas tamponade for stage I-IV macular holes. METHODS: Over a period of 10 months, a consecutive series of 30 patients and 31 eyes with macular holes underwent pre- and postoperative automatic perimetry (Octopus 07, 70 degrees) and macular perimetry (Octopus M1, 24 degrees) to characterize the pattern of visual field defects after vitrectomy with gas tamponade. Success rates were evaluated and complications were analyzed. RESULTS: Anatomic success after one surgical procedure was achieved in 85% of cases, visual improvement in 58%. Some 70.1% of patients had peripheral scotomas postoperatively; some of these were highly symptomatic and others were detected by visual field testing only. The most consistently affected areas were the temporal and lower periphery of the visual field. The central visual field, however, was not disturbed. CONCLUSION: Visual field loss after otherwise successful surgery for macular holes is an unexpectedly frequent and serious complication. The authors discuss various factors that may contribute to the postoperative scotomas. From the localization of the scotomas it seems most likely that they are caused by the persistent pressure of the gas bubble on the peripheral retina. Further investigations are necessary to confirm this hypothesis, and ways must be found to avoid this complication in order to be able to proceed with this otherwise promising new indication group for vitreous surgery.
