Case ReportsCase report: acute spontaneous Achilles tendon rupture in a patient with giant cell arteritis.
We report a case of a 69-yr-old previously healthy man with acute spontaneous Achilles tendon rupture and severe tendonitis, which occurred after 2 weeks of steroid therapy for newly diagnosed giant cell arteritis. The Achilles tendon rupture was treated conservatively and the tendonitis resolved incrementally with steroid dose reduction. The patient made a complete recovery. ⋯ The tendon rupture early in the course of high-dose steroid therapy expands the understanding of this adverse reaction, which was previously reported only with long-term steroid therapy. The severe tendonitis responded to steroid therapy reduction suggesting a dose correlation. This report adds to a sole previous report of a spontaneous Achilles tendon rupture associated with giant cell arteritis.

Novel radiator for carbon dioxide absorbents in low-flow anesthesia.
During long-term low-flow sevoflurane anesthesia, dew formation and the generation of compound A are increased in the anesthesia circuit because of elevated soda lime temperature. The object of this study was to develop a novel radiator for carbon dioxide absorbents used for long durations of low-flow sevoflurane anesthesia. Eleven female swine were divided into two groups comprising a "radiator" group (n = 5) that used a novel radiator for carbon dioxide absorbents and a "control" group (n = 6) that used a conventional canister. ⋯ In the "radiator" group, the temperature of soda lime stayed at 30 degrees C, and the water content of soda lime was retained with no dew formation in the inspiratory valve. In addition, compound A concentration was reduced. In conclusion, radiation of soda lime reduced the amounts of condensation formed and the concentration of compound A in the anesthetic circuit, and allowed long term low-flow anesthesia without equipment malfunction.

Ultrastructural findings in metastatic bronchioloalveolar carcinoma.
This study was prompted by the recent revision of the definition of bronchioloalveolar carcinoma (BAC) that defines BAC, light microscopically, as a non-invasive carcinoma. Doubt has been raised whether BACs retain certain specific microscopic features after becoming invasive or metastatic. ⋯ The remaining case did not show ultrastructural features of BAC. These findings suggest that most BACs retain some of their ultrastructural features after becoming metastatic neoplasms.
