Cardio-oncology is a critical field due to the escalating significance of cardiovascular toxicity as a side effect of anti‑ cancer treatments. Cancer therapy-related cardiac dysfunction (CTRCD) is a prevalent condition associated with car‑ diovascular toxicity, necessitating effective strategies for prediction, monitoring, management, and tracking. This comprehensive review examines the definition and risk stratification of CTRCD, explores monitoring approaches during anticancer therapy, and highlights specific cardiovascular toxicities linked to various cancer treatments. These include anthracyclines, HER2-targeted agents, vascular endothelial growth factor inhibitors, immune checkpoint inhibitors, chimeric antigen receptor T-cell therapies, and tumor-infiltrating lymphocytes therapies. Incorporating the Korean data, this review offers insights into the regional nuances in managing CTRCD. Using systematic follow-up incorporating cardiovascular imaging and biomarkers, a better understanding and management of CTRCD can be achieved, optimizing the cardiovascular health of both cancer patients and survivors.

Objective: To evaluate the antibacterial activity of Cinnamomum verum (C. verum) from 32 different essential oils against cariogenic bacteria, Streptococcus mutans (S. mutans) and Streptococcus sobrinus (S. sobrinus). Methods: The antibacterial activities of each essential oil were individually investigated against S. mutans and S. sobrinus. The essential oil of C. verum was selected for further evaluation against S. mutans and S. sobrinus. Gas chromatography mass spectrometry was used to determine the major constituents of C. verum essential oil. In addition, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration of the most effective constituent was investigated. Results: The essential oil from C. verum exhibited the greatest antibacterial activity. Gas chromatography mass spectrometry analysis revealed that the major components of C. verum essential oil were cinnamaldehyde (56.3%), cinnamyl acetate (7.1%) and β-phellandrene (6.3%). The MIC of cinnamaldehyde was measured using broth dilution assays. The MIC of cinnamaldehyde was 0.02% (v/v) against both bacterial strains tested. The minimum bactericidal concentration of cinnamaldehyde against S. mutans and S. sobrinus were 0.2% and 0.1% (v/v), respectively. Conclusions: The essential oil of C. verum and its major component cinnamaldehyde possessed considerable in vitro antibacterial activities against cariogenic bacteria, S. mutans and S. sobrinus strains. These results showed that the essential oil of C. verum and its bioactive component, cinnamaldehyde, have potential for application as natural agents for the prevention and treatment of dental caries.

BACKGROUND: We made a comparative study on the antiemetic effect of midazolam and ondansetron added to intravenous patient-controlled analgesia (PCA) using fentanyl with gynecologic patients undergoing pelviscopic surgery. METHODS: The PCA using 20 microg/kg of fentanyl was started in all groups postoperatively. A dose of 16 mg of ondansetron was added to the PCA of group O (n = 30). A dose of 5 mg of midazolam was added to the PCA of group M (n = 30). While 16 mg of ondansetron and 5 mg of midazolam were added to the PCA of group MO (n = 30). Total volume of the PCA was 60 ml, and the PCA system was programmed to deliver 0.5 ml/h of continuous doses and a 0.5 ml bolus on demand, with a 15 minutes lockout interval. The incidence of postoperative nausea and vomiting (PONV), sedation score, visual analog scale (VAS) for pain, and rescue drug dose for PONV were investigated at the postanesthesia care unit (PACU), 6 hours, and 24 hours after recovery. RESULTS: The incidence of PONV in group MO was significantly lower than in group O at PACU, 24 hours after recovery (P < 0.05). The sedation score and VAS pain score showed no differences among all groups. CONCLUSIONS: Midazolam added to PCA using fentanyl proved more effective than ondansetron in preventing PONV without adverse effects.

Seizure associated with antiemetics is rare. We report seizure associated with a 5-HT3 receptor antagonist in a 38 years old female. The patient underwent ureterorenoscopic lithotripsy due to left upper ureter stone. After operation, the patient complained of nausea in the postanesthetic recovery unit. In order to subside symptom, the patient was administrated 5-HT3 receptor antagonist, palonosetron, 0.075 mg intravenously. Shortly after administration of that, the patient developed generalized tonic-clonic seizures. The symptom was subsided after midazolam and thiopental sodium were injected. But 40 minutes later, seizure recurred and subsided with midazolam again. The patient recovered completely without any specific sequelae.

BACKGROUND: In the midthoracic region, a fluroscope guided epidural block has been proposed by using a pedicle as a landmark to show the height of the interlaminar space (Nagaro's method). However, clinical implication of this method was not fully evaluated. We studied the clinical usefulness of a fluoroscope guided thoracic epidural block in the midthoracic region. METHODS: Twenty four patients were scheduled to receive an epidural block at the T6-7 intervertebral space. The patients were placed in the prone position. The needle entry point was located at the junction between midline of the pedicle paralleled to the midline of the T7 vertebral body (VB) and the lower border of T7 VB on anteroposterior view of the fluoroscope. The needle touched and walked up the lamina, and the interlaminar space (ILS) was sought near the midline of the VB at the height of the pedicle. RESULTS: The authors could not insert an epidural needle at T6-7 ILS in two patients and it was instead inserted at T5-6 ILS. However, other patients showed easy insertion at T6-7 ILS. The mean inward and upward angulations were 25degrees and 55degrees respectively. The mean actual depth and calculated depth from skin to thoracic epidural space were 5.1 cm and 6.1 cm respectively. Significant correlation between actual needle depth and body weight, podendal index (kg/m) or calculated needle depth was noted. CONCLUSIONS: The fluorposcope guided epidural block by Nagaro's method was useful in the midthoracic region. However, further study for the caudal shift of needle entry point may be needed.

Cankers are localized dead areas in the bark of stems, branches or twigs of many types of trees and shrubs, and are usually caused by fungi. We observed severe canker symptoms in oak trees located in Gyeongnam province in 2011. A total 31 trees were discovered with cankers of varied size, with an average of 48.5 x 15.2 cm. Black, half-rounded globular mound shaped stromata were associated with the cankers, and the asci of the fungi associated with the cankers were cylindrical shaped with their spore-bearing parts being up to 84 microm in length. The average fungal ascospores size was 7.59 x 4.23 microm. The internal transcribed spacer sequence for the canker causing fungus showed 99% similarity to the sequence of Annulohypoxylon truncatum. In this study, the isolated fungus was precisely described and then compared with fungi of similar taxa.

BACKGROUND: Emergence agitation frequently occurs after desflurane anesthesia in children. We designed this study to find the optimal dose of fentanyl for the prevention of emergence agitation after desflurane anesthesia in children for tonsillectomy. METHODS: Eighty-one patients (3-10 yr) receiving desflurane anesthesia for tonsillectomy was randomly allocated to one of 3 groups. Fentanyl 1 microg/kg (group 1, n = 26), 2 microg/kg (group 2, n = 27), 3 microg/kg (group 3, n = 28) was administered intravenously just before inducing anesthesia. Anesthesia was maintained with desflurane. The recovery characteristics, such as the time to first movement, extubation and discharge from the recovery room were assessed. And patients reported their frequency of emergence agitation and severity of postoperative pain at recovery room. RESULTS: There were no significant differences between the three groups regarding the time to extubation and discharge from the recovery room. The incidence of emergence agitation was 42% in group 1, 25% in group 2, 10% in group 3 and that was significantly lower in group 3 than in group 1 (P < 0.05). The incidence of severe pain was lower in group 3 than in group 1 and group 2 (P < 0.05). CONCLUSIONS: In children undergoing tonsillectomy with desflurane anesthesia, 2 microg/kg and 3 microg/kg of fentanyl given just before induction had a reduced incidence of emergence agitation without a delay in recovery.

BACKGROUND: Lumbar epidural block is a common regional anesthetic/analgesic technique. The depth of the epidural space beneath the skin surface varies from patient to patient at the same vertebral level. It also varies at different levels of the spinal column in the same patient. This study was performed to evaluate the correlations between the lumbar epidural depth and physical measurements depending on the puncture site. METHODS: Data was gathered from 1,653 patients who were undergoing elective lumbar epidural blocks for anesthesia during surgical procedures. The age, gender, height and weight were obtained from the medical records. We calculated the physical parameters such as the weight/height ratio, the body mass index (BMI) and Broca's index. Pearson's correlation analysis and regression testing between the lumbar epidural depth and the physical measurements were performed. RESULTS: The epidural depths at the L2-3, L3-4, L4-5 and L5-S1 intervertebral space were 4.4 +/- 0.62, 4.6 +/- 0.69, 4.6 +/- 0.69 and 4.1 +/- 0.52 cm, respectively. A significant correlation was found between the epidural depth and the weight/height ratio and BMI. CONCLUSIONS: The weight/height ratio and BMI showed the highest correlation with the lumbar epidural depth.

PURPOSE: A study was designed to assess the effect of intraperitoneal instillation of ropivacaine in larparoscopic cholecystectomy patients using computerized patient controlled anesthesia (PCA). METHODS: From January 2009 to June 2009, 40 patients with uncomplicated, symptomatic cholecystitis with cholelithiasis who were referred to Chung-Ang University Medical Center for laparoscopic cholecystectomy were included in the study. Patients in group C (control group) received normal saline 100 ml and those in group I (instillation group) received intraperitoneal instillation of 2 mg/kg of ropivacaine diluted in 100 ml saline at the initiation of pneumoperitoneum. Patients were assessed for pain by blinded investigators at 6 time intervals after surgery; 2 hr, 4 hr, 8 hr, 12 hr, 24 hr, and 48 hr. The frequency at which patients pushed the button of the PCA on bolus requirement (FPB) was assessed by a patient-controlled module on the PCA machine. RESULTS: The mean total fentanyl consumption was lower in group I (367.39+/-85.88) than in group C (535+/-100.29) during the 48 hours (P<0.001). Fentanyl velocity and FPB showed significant difference between the groups (P<0.005). Visual analogue scale (VAS) measured pain scores were significantly lower in group I than in group C at 4 hr (P=0.027), 8 hr (P=0.010), 12 hr (P=0.011). CONCLUSION: Intraperitoneal instillation of ropivacaine at the beginning of laparoscopic cholecystectomy (LC) combined with normal saline infusion is an effective method for reducing pain after LC.
