Gastric emptying time after breakfast in healthy adult volunteers using ultrasonography.
There is little evidence of gastric excretion after ingestion of solids. We examined gastric emptying times after ingesting normal breakfast in healthy adult volunteer using ultrasonography. Eight adult volunteers fasted for 8 h, and we examined the gastric antral area in the right lateral decubitus position using ultrasonography. ⋯ The calculated gastric emptying time was 276.4 ± 58.9 min. This result shows that gastric emptying time was lower than 5 h average after a typical breakfast that contains various food in healthy adult volunteers. However, further research is necessary to establish the clinical safety implications of these findings.

Distinct, sex-dependent miRNA signatures in piglet hippocampus induced by a clinically relevant isoflurane exposure: a pilot study.
To evaluate the effects of sex on miRNA expression in the hippocampus after isoflurane anesthesia in a neonatal piglet model. ⋯ In the neonatal piglet hippocampus, miRNA expression was highly conserved. There was no overlap in miRNA expression between isoflurane-exposed males and females, suggesting sex differences in isoflurane-induced miRNA expression. These results support the hypothesis that a clinically relevant exposure to isoflurane induces distinct miRNA signatures in the hippocampus of neonatal male and female piglets. Their functional relevance in anesthesia-induced neurotoxicity remains unknown, although changes in specific miRNAs may either contribute to or protect against anesthesia-induced neurotoxicity.

Association between treatment-related early changes in psychological factors and development of postherpetic neuralgia.
To examine the association between catastrophizing and pain intensity with acute herpes zoster, and the association of treatment-related early changes in depressive symptoms, anxiety, and catastrophizing with postherpetic neuralgia (PHN) development, independent of acute pain intensity. ⋯ Catastrophizing was associated with acute pain intensity, and lower pain-related catastrophizing among patients with acute herpes zoster was associated with less risk of PHN development, independent of acute pain intensity.

The 95th KoreAnesthesia Meeting was held successfully over 3 days from November 8 to 10, 2018 at Seoul Dragon-City Hotelplex, featuring 62 overseas speakers and 2960 attendees from 26 countries. KoreAnesthesia is the largest annual event hosted by the Korean Society of Anesthesiologists (KSA). The KSA hopes that many members of the Japanese Society of Anesthesiologists and readers of the Journal of Anesthesia will join us at the forthcoming KoreAnesthesia 2019 from October 31 to November 2, 2019 at Paradise City Hotel, Incheon, South Korea.

Case ReportsCerebral regional oxygen saturation: a useful monitor during a surgical procedure involving the right-sided aortic arch in an infant.
A right aortic arch with an aberrant left subclavian artery and a Kommerell's diverticulum represents a rare anatomic variant carrying the risk of dissection or rupture. Resection of the diverticulum and re-implantation of the left subclavian artery during childhood have been recommended. Because of the risk of cerebral blood flow reduction during the aberrant subclavian artery re-implantation to the common carotid artery, monitoring and prompt measures to curb blood flow reduction are required. ⋯ We increased the end-tidal CO2 (EtCO2), mean arterial pressure, and a fraction of inspired oxygen, successfully restoring the rSO2 to the initial level. No postoperative neurological complications were observed. Our experience with this patient suggests that rSO2 monitoring is a useful, and intervention protocol including hypercapnia, elevated mean arterial pressure, and hyperoxia to counter the decreased cerebral blood flow is effective in infant patients undergoing right-sided aortic arch surgery.
