Case ReportsNegative-pressure pulmonary edema after resection of mediastinum thyroid goiter.
Negative-pressure pulmonary edema (NPPE) is an uncommon but life-threatening complication of acute or chronic upper airway obstruction; however, there are few reports of NPPE after giant goiter resection. We report a case with severe NPPE induced by the resection of a mediastinum thyroid goiter. The patient was successfully treated by non-invasive positive airway ventilation (NPPV).

Cost-utility analysis of cochlear implants in Korea using different measures of utility.
All cost-utility ratios obtained using the various measures of utility except quality well-being (QWB) were below 25,000 dollars per quality-adjusted life year (QALY). Therefore, treatment of post-lingual deaf adults with cochlear implants improves the quality of life at a reasonable direct cost and appears to produce net savings for Korean society. ⋯ Recipients used implants for an average of 5.6 years. The mean VAS, HUI, EQ-5D, and QWB score increased by 0.33 (from 0.27 before implantation to 0.60 at survey), 0.36 (0.29 to 0.65), 0.26 (0.52 to 0.78), and 0.16 (0.45 to 0.61), respectively. The discounted direct cost was 22,320 dollars, which yielded a cost-utility ratio of 19,223 dollars per QALY using VAS, 17,387 dollars per QALY using HUI, 24,604 dollars per QALY using EQ-5D, and 40,474 dollars per QALY using QWB.
