First Report of Myrothecium roridum Causing Leaf and Stem Rot Disease on Peperomia quadrangularis in Korea

In 2010, symptoms of leaf and stem rot were observed on potted plants (Peperomia quadrangularis) in a greenhouse in Yongin, Korea. The causative pathogen was identified as Myrothecium roridum based on morphological data, internal transcribed spacer sequence analysis, and pathogenicity test. To our knowledge, this is the first report of M. roridum causing leaf and stem rot disease on P. quadrangularis in Korea and elsewhere worldwide.

A comparison of femoral/sciatic nerve block with lateral femoral cutaneous nerve block and combined spinal epidural anesthesia for total knee replacement arthroplasty / 대한마취과학회지

BACKGROUND: Several factors, such as compromised cardiopulmonary function, anticoagulative therapy, or anatomical deformity in the elderly, prevent general anesthesia and neuraxial blockade from being conducted for total knee replacement arthroplasty (TKRA). We investigated the efficacy of femoral/sciatic nerve block with lateral femoral cutaneous nerve block (FSNB) as an alternative procedure in comparison with combined spinal epidural nerve block (CSE) in patients undergoing TKRA. METHODS: In this observational study, 80 American Society of Anesthesiologists physical status I-III patients scheduled for elective unilateral TKRA underwent CSE (n = 40) or FSNB (n = 40). Perioperative side effects, intraoperative medications, duration and remaining amount of intravenous patient-controlled analgesia, rate of satisfaction with the surgical anesthesia and postoperative analgesia, willingness to recommend the same surgical anesthesia and postoperative analgesia to others, and postoperative visual analog scale pain scores were assessed. Statistical analysis was done using Chi-square test, Student's t-test, and repeated-measures analysis of variances. RESULTS: There was significantly more use of antihypertensives, analgesics, and sedatives in the FSNB group. There were no significant differences of perioperative side effects, duration and remaining amount of intravenous patient-controlled analgesia, rate of satisfaction with the surgical anesthesia and postoperative analgesia, willingness to recommend the same surgical anesthesia and postoperative analgesia to others, and postoperative visual analog scale scores between the two groups. CONCLUSIONS: FSNB with a sophisticated use of antihypertensives, analgesics, and sedatives to supplement insufficient block offers a practical alternative to CSE for TKRAs.
