Circumscribed to endemic areas throughout tropical countries, filariasis is a rare and unknown disease in Europe. We report four cases of calcified filariasis involving the breast, supporting the diagnosis on the typical mammographic appearance of the calcified worms and the past history of filarial infection. Few reports have been published in the(More)
This paper brings together two bodies of literature. One of them is a literature on the special role of the consumer in retailing. The other one is the literature on customer satisfaction. This joining of literatures is accomplished by identifying distribution services as outputs of retail firms and fixed inputs into the production functions of consumers.(More)
Intestinal pneumatosis (presence of gas in the intestinal wall and in the portomeseteric veins) is an infrequent clinical situation that has been associated with extended bowel necrosis and fatal outcome. However, there are other reasons that can justify these findings without such an outcome. Recent advances in diagnostic imaging techniques, especially(More)
This paper brings together two bodies of literature in retailing. One of them is an older literature on the special role of the consumer in retailing. The other one is a more recent one on the measurement of customer satisfaction in retailing. This joining of literatures is accomplished by identifying distribution services as outputs of retail firms and(More)
This paper addresses two related issues. First, it adapts a framework developed for the analysis of customer satisfaction in retailing to the case of gas stations, and implements this framework with unique survey data. The results show that the determinants of customer satisfaction are different for self service and full service stations. Second, it looks(More)
We report an infrequent mammographic case in which a gross-calcified lipid cyst evolved spontaneously to form a cluster of pleomorphic microcalcifications which were indistinguishable from those seen in breast cancer. The biopsy performed was consistent with fat necrosis. Ultrasonography of the specimen showed a nodule with mixed echogenicity surrounded by(More)
We describe a novel technique for marking non-palpable breast lesions with the aim of selecting the best approach prior to performing a biopsy. The technique employs a new coil, specifically designed for breast localization, guided by stereotaxy. This technique is reserved for selected cases in which the lesion is seen peripherally in only one mammographic(More)
