Fungal osteomyelitis of calcaneus due to Candida albicans: a case report.

Osteomyelitis can be a challenging entity to treat. Because of the emergence of risk factors, including broad-spectrum antibiotics, intravenous drug abuse, immunocompromised hosts, and other factors, opportunistic pathogens have increased in prevalence in bone infections. A review of the published data revealed few reported cases of fungal osteomyelitis localized to the foot. In the present report, we describe a rare case of fungal osteomyelitis localized to the calcaneus in an elderly female patient who was successfully treated with surgical debridement and a 6-week course of oral fluconazole.

Results of modified lapidus arthrodesis procedure using medial eminence as an interpositional autograft.

The Lapidus procedure has received wide acceptance as a valuable operation for correcting moderate to severe hallux valgus, especially in the presence of hypermobility. However, shortening of the first ray inherently occurs as the first metatarsocuneiform joint cartilage and subchondral bone are resected in preparation for arthrodesis. The purpose of this study was to radiographically compare the degree of shortening of the first ray with and without the use of the first metatarsal medial eminence as an interpositional autograft at the site of metatarsocuneiform fusion. Preoperative and postoperative radiographs were measured in 35 consecutive patients who underwent 37 modified Lapidus procedures for hallux valgus repair. In group A, 20 surgeries were performed without use of the interpositional autograft, and served as the control. In group B, 14 surgeries were performed using the medial eminence as an interpositional autograft. The mean amount of first ray shortening was 5.3 ± 1.66 mm in group A and 2.69 ± 1.56 mm in group B, and this difference was statistically significant (P < .001). All patients progressed to complete union, and the median follow-up was 6 months (range, 4-60). Based on these results, the use of the medial eminence as an interpositional autograft in conjunction with Lapidus arthrodesis resulted in a 49.2% reduction in the amount of shortening of the first ray and proved to be a useful source of readily available bone graft.

The FinFET Breakthrough and Networks of Innovation in the Semiconductor Industry, 1980-2005: Applying Digital Tools to the History of Technology.

The "FinFET" design for transistors, developed at the University of California, Berkeley, in the 1990s, represented a major leap forward in the semiconductor industry. Understanding its origins and importance requires deep knowledge of local factors, such as the relationships among the lab's principal investigators, students, staff, and the institution. It also requires understanding this lab within the broader network of relationships that comprise the semiconductor industry-a much more difficult task using traditional historical methods, due to the paucity of sources on industrial research. This article is simultaneously 1) a history of an impactful technology and its social context, 2) an experiment in using data tools and visualizations as a complement to archival and oral history sources, to clarify and explore these "big picture" dimensions, and 3) an introduction to specific data visualization tools that we hope will be useful to historians of technology more generally.
