Generally, odorant molecules are detected by olfactory receptors, which are specialized chemoreceptors expressed in olfactory neurons. Besides odorant molecules, certain volatile molecules can be inhaled through the respiratory tract, often leading to pathophysiological changes in the body. These inhaled molecules mediate cellular signaling through the activation of the Ca 2+ -permeable transient receptor potential (TRP) channels in peripheral tissues. This review provides a comprehensive overview of TRP channels that are involved in the detection and response to volatile molecules, including hazardous substances, anesthetics, plant-derived compounds, and pheromones. The review aims to shed light on the biological mechanisms underlying the sensing of inhaled volatile molecules. Therefore, this review will contribute to a better understanding of the roles of TRP channels in the response to inhaled molecules, providing insights into their implications for human health and disease.

BACKGROUNDS/AIMS: To compare the clinical outcomes of intraoperative radiofrequency ablation (RFA) and non-anatomical hepatic resection (NAHR) for small hepatocellular carcinoma (HCC). METHODS: From February 2007 to January 2015, clinical outcomes of thirty four patients with HCC receiving RFA or NAHR were compared, retrospectively. RESULTS: There was no difference of patient and tumor characteristic between the two groups that received RFA or NAHR. The 1, 2, and 3-year recurrence rates following RFA were 32.2%, 32.2% and 59.3% respectively, and 6.7%, 33.3% and 33.3% following NAHR respectively (p=0.287). The 1, 2 and 3-year overall survival (OS) rates following RFA were 100%, 88.9% and 76.2% respectively, and 100%, 85.6% and 85.6%, respectively, following NAHR (p=0.869). We did not find a definite statistical difference in recurrence rate and OS rate between the two groups. In the multivariate analysis, number of tumor was an independent prognostic factor for recurrence and albumin was an independent prognostic factor for OS. CONCLUSIONS: We recommend non-anatomical hepatic resection rather than intraoperative RFA in small sized HCC, due to a higher recurrence rate in intraoperative RFA. Intraoperative RFA was inferior to non-anatomical hepatic resection in terms of recurrence rate. We need to select the optimal treatment considering liver function and possibility of recurrence.

Journal of Korean Medical Science 2023;38(18):e137-
Background:
The purpose of this study was to investigate the change in the incidence rate, length of hospital stay (LOS), in-hospital mortality rate, and surgical method of hip fractures during the coronavirus disease 2019 (COVID-19) pandemic in South Korea where lockdown restrictions were not implemented.
Methods:
We calculated the expected values of the incidence of hip fractures, in-hospital mortality and LOS of hip fracture patients in 2020 (COVID period) based hip fracture database of the Korean National Health Insurance Review and Assessment (HIRA) during a 9-year period from 2011 to 2019 (pre-COVID period). A generalized estimating equation model with Poisson distribution and logarithmic link function was used to estimate adjusted annual percent change (PC) of incidence rate and 95% confidence intervals (CIs). Then, we compared the annual incidence, in-hospital mortality rate and LOS in 2020 with the expected values.
Results:
The overall incidence rate of hip fracture in 2020 was not significantly different from the expected value (PC, −5%; 95% CI, −13 to 4; P = 0.280). In women, the incidence rate of hip fracture in age groups over 70 years was smaller than the predicted value (P < 0.001). The in-hospital mortality rate was not significantly different from the expected value (PC, 5%; 95% CI, −8 to 19; P = 0.461). The mean LOS was larger than the expected value by 2% (PC, 2%; 95% CI, 1 to 3; P < 0.001). In intertrochanteric fracture, the proportion of internal fixation was smaller than the predicted value by 2% (PC, −2%; 95% CI, −3 to −1; P < 0.001), and that of hemiarthroplasty was larger than the predicted value by 8% (PC, 8%; 95% CI, 4 to 14; P < 0.001).
Conclusions
In 2020, the incidence rate of hip fracture did not significantly decrease, and inhospital mortality rate did not significantly increase compared to the expected rates, which were projected based on the HIRA hip fracture data from 2011 to 2019. Only LOS increased slightly.

OBJECTIVE: To analyze the clinical characteristics of total laparoscopic hysterectomy. METHODS: Clinical data about 600 cases who received TLH were collected and the hospital stay, operation time and complication were evaluated. RESULTS: The most common indications for TLH were uterine myomas, adenomyosis, severe endometriosis and cervical intraepithelial neoplasia. Mean operating time was 90 minutes (range 35-200 min) and hospital stay was 3 days (range 2 days-10 days). The most important factors for the surgery time were uterine size, assistant's skill and presence of adhesions (obliteration of the cul-de-sac due to severe pelvic endometriosis). Several techniques were used, including bipolar coagulation of the ovarian and uterine vessels, and suture of the stump. A special uterine manipulator (RUMITM uterine manipulator with colpotomizer and pneumooccluder balloon) used in all procedures aided in anatomic definition and performing the circumferential colpotomy. We had two cases of ureteral obliteration by using bipolar coagulator, and 3 cases of bladder injuries during operation which was diagnosed and immediately repaired laparoscopically. We had two cases of ureterovaginal fistula, two cases of postoperative ileus and one case of bowel perforation. But there were no cases of death, thrombophlebitis or other pulmonary complications. CONCLUSIONS: Total laparoscopic hysterectomy can be performed safely and effectively when the surgical team is sufficiently trained. And we believe that total laparoscopic hysterectomy offers benefits to the patients in the form of less post-operative pain, shorter time in hospital.

Objective:
This study aims to empirically determine if indirect exposure to client violence has significant negative effects on social workers’ posttraumatic stress disorder (PTSD) the same way direct victimization does.
Methods:
Using a sample of 1,359 social workers drawn from the data collected by the Seoul Association of Social Workers, this study employs descriptive statistics to examine the prevalence of indirect experiences with client violence, and utilizes a series of hierarchical regression analyses to demonstrate the potential impact of indirect exposure to client violence on PTSD. To assess the severity of PTSD symptoms in participants, the Korean version of the Impact of Events Scale-Revised (IES-R-K) was employed.
Results:
A descriptive analysis shows that 12.4% of the sample indirectly experienced client violence by witnessing it or hearing about a violent incident, whereas 6.0% were directly victimized. Hierarchical regression analyses indicate that direct experience (B=4.548, p<0.05) and indirect experience (B=7.297, p<0.001) of client violence have a significant association with the scores on IES-R-K. An investigation of the interaction terms between experiences of client violence and violence-prevention training illustrates that such training significantly moderates the influence on the scores on IES-R-K from indirect exposure to client violence (B=-8.639, p<0.01).
Conclusion
Social workers who are indirectly exposed to client violence experience PTSD symptoms comparable to their colleagues who were directly victimized. Further, violence-prevention training has greater ameliorative effects with regard to indirect experience of client violence than for direct victimization.

The objective of this study is to evaluate short-term results of total laparoscopic hysterectomy with those of total abdominal hysterectomy and laparoscopically assisted vaginal hysterectomy in a retrospective study. We compared patient's age, mean uterine weight, total operating time, length of hospital stay and perioperative hemoglobin concentration change between total laparoscopic hysterectomy (300 patients) and total abdominal hysterectomy (100 patients) and laparoscopically assisted vaginal hysterectomy (52 patients). There were no differences in terms of patient's age, parity between the three groups. There were 7 minor complications in the laparoscopically assisted vaginal hysterectomy group compared with 9 minor complications in the abdominal hysterectomy group and 14 minor complications in the total laparoscopic hysterectomy group (P not significant). The length of hospital stay was significantly shorter for total laparoscopic hysterectomy than laparoscopically assisted vaginal hysterectomy and total abdominal hysterectomy (p<.001). This study demonstrates that laparoscopic-assisted vaginal hysterectomy and total laparoscopic hysterectomy appears to be as safe as laparotomy and may replace abdominal hysterectomy in most patients and generally has the advantage of shorter hospital stay and earlier return to normal activities.

Objectives:
Although the characteristics of different aggression subtypes provide important information in establishing treatment and prevention strategies in schizophrenia patients, limited information is available about the characteristics of the aggressive subtype in schizophrenia patients in South Korea. The present study was designed to compare the demographic and psychological characteristics across the impulsive and premeditated aggression subtypes in schizophrenia patients in South Korea who had committed a crime.
Methods:
We enrolled 116 schizophrenia spectrum disorder patients who were admitted to the National Forensic Psychiatric Hospital. Using the criminal and interview records, the study subjects were divided into 83 impulsive and 33 premeditated aggression groups. The subjects’ demographic and psychological characteristics were summarized and compared across aggression subtypes.
Results:
Compared to the premeditated aggression group, the impulsive aggression group had a higher intelligent quotient and a lower rate of physical and sexual abuse experience.
Conclusion
To our knowledge, this is the first study to describe the characteristics of aggression subtypes in schizophrenia patients in South Korea who had committed a crime. Our results suggest that different treatment and prevention strategies should be considered for each aggression subtype.
