Background:
Sarcopenia is associated with postoperative complications; however, its impact on the quality of postoperative recovery, such as postoperative nausea and vomiting (PONV) and pain, remains unclear. We investigated the association of preoperative lumbar skeletal muscle mass index (LSMI) with PONV, postoperative pain, and complications.
Methods:
Medical records of 756 patients who underwent pylorus-preserving pancreatoduodenectomy (PPPD) were retrospectively reviewed. The skeletal muscle areas were measured on abdominal computed tomography (CT) images. LSMI was calculated by dividing the skeletal muscle area by the square of the patient’s height. We analyzed the correlations between preoperative LSMI calibrated with confounding variables and PONV scores, PONV occurrence, pain scores, rescue analgesic administration, postoperative complications, and length of hospital stay.
Results:
The median (1Q, 3Q) LSMI was 47.72 (40.74, 53.41) cm2/m2. The incidence rates of PONV according to time period were as follows: post-anesthesia care unit, 42/756 (5.6%); 0–6 h, 54/756 (7.1%); 6–24 h, 120/756 (15.9%); 24–48 h, 46/756 (6.1%); and overall, 234/756 (31.0%). The incidence of PONV was inversely correlated with LSMI 24–48 h post-surgery and overall. LSMI and PONV scores were negatively associated 6–24 h and 24–48 h post-surgery. There was no association between LSMI and postoperative pain scores, rescue analgesic administration, complications, or length of hospital stay.
Conclusions
Preoperative LSMI was associated with PONV in patients undergoing PPPD. Therefore, LSMI measured on preoperative abdominal CT can be a predictive indicator of PONV. Appropriate PONV prophylaxis is necessary in patients with low LSMI before PPPD.

To investigate the effects of maternal hyperthermia on early odontogenesis,pregnant Hsp70 knock-out and wild type mice at embryonic day (ED)8.5 were immersed in a 43 degrees C water bath until their core body temperature reached that temperature,and then given a further 5 min of hyperthermia.Untreated Hsp70 WT mice fetuses were used as the control group.Fetuses were collected at EDs 13.5,15.5 and 17.5.Developing teeth in the mandible were processed for histological and immunohistochemical studies.Tissue sections were immunostained for FGF-8 and FGF -4 and observed using light microscopy.In the controls, FGF-8 immunolocalization was observed in cells within the dental lamina and in apically located dental epithelium at ED 13.5.However,a few cells were immunopositive in the heat shocked (HS)group.At EDs 15.5 and 17.5 of the control group,the basal lamina adjacent to the dental pulp showed positive immunostaining.In contrast,most of the dental epithelium was immunopositive at ED 15.5 in the HS group and inner and outer dental epithelial cells were continuously immunopositive by ED 17.5.FGF-4 immunolocalization was found in apical dental epithelium at ED 13.3 in the control group,but no such positive reaction was observed in the HS group.At ED 15.5 in the controls,basal lamina and dental epithelium near the cervical loop were immunopositive.In contrast,early cap-stage teeth had cells near the mouth of the dental bud and cervical loop that were immunopositive to FGF-4 in the HS group.In controls at ED 17.5,cells near the future secondary enamel knot were immunopositive,whereas most of the dental epithelium except for cells in the mouth of the dental lamina was negative in the HS group.Thus,maternal hyperthermia may inhibit normal odontogenesis through sustained production of FGF-8 and downregulation of FGF-4.

Pseudoaneurysm of the abdominal wall is a possible but very rare clinical entity. It is a known complication of surgery, trauma, or arterial puncture, but it is rarely spontaneous. Even though it can usually present with a wide range of local symptoms, it can cause referred pain via spinal cord, which is cross-excited with afferent sympathetic nervous system. We report a case of right arm pain which was referred from a small abdominal pseudoaneurysm like a referred pain from gall bladder. This rare entity should be considered in the differential for pain management in case that the pain does not resolve with medication or interventional pain management.

PURPOSE: In elderly and patients with underlying diseases, mortality rate is increased when compared to rib fractures which occurred in other patients. Because there is a shortage of emergency physicians or real-time consultation with radiologists in many countries, it is necessary to receive a formal image reading remotely from an expert. We suggested the use of iPad in X-ray reading and compared the diagnostic validity of iPad, which was highly portable, with that of liquid crystal display (LCD) monitor. METHODS: Fifty four X-ray cases of rib fracture and 54 cases without rib fracture were randomized and reviewed by 10 emergency physicians. A total of 108 cases were divided 1st to 54th and 55th to 108th. Two sessions were separated with a four-week interval. If the reviewer interpreted the 1st to 54th with iPad, they did 55th to 108th with LCD monitor. Reviewers reported the presence of rib fracture, the number of fractured ribs, and diagnostic confidence of 5-scale. RESULTS: The interobserver agreement among reviewers in LCD and iPad was 0.551, 0.524 in Fleiss-kappa value. The intraobserver agreement between tools for each reviewer was 0.410-0.859 (Mean=0.628+/-0.150). Reviewers showed sensitivity over 0.810 regardless of the tool; 0.810- 0.966 (Mean=0.879+/- 0.054) in LCD, 0.828-1.000 (Mean=0.898+/-0.052) in iPad. The specificity was 0.520- 0.860 (Mean=0.750+/-0.117) in LCD and 0.560-0.880 (Mean=0.708+/-0.111) in iPad. Therefore, remote consultation of X-ray by iPad with a specialist was possible with minimized temporal and spatial limits in the emergency room. CONCLUSION: In our study, there was no statistical difference in the diagnosis of rib fracture by X-ray via iPad or LCD. Therefore, remote consultation of X-ray by iPad with a specialist in the emergency room was possible, with temporal and spatial limits by iPad.

OBJECTIVE: The systemic inflammatory response syndrome (SIRS) criteria used in the triage scale have been implemented incompletely without laboratory data, such as the white blood cell (WBC) count, so the validity of SIRS as a triage tool has been uncertain. This study assessed the validity of the Korean Triage and Acuity Scale (KTAS) in applying SIRS with or without a WBC count. METHODS: The KTAS level was simulated by the number of SIRS criteria. This new KTAS level that did not apply the WBC count was defined as the partial-simulated KTAS (PS-KTAS), and the KTAS level including the WBC count was called the total-simulated KTAS (TS-KTAS). The authors used the intensive care unit (ICU), overall admission rate, and use of emergent interventions as the primary outcomes. RESULTS: A total of 1,077 patients with a suspected infection were triaged using the SIRS in KTAS. Multivariable logistic regression analysis showed that the odds ratio for overall admission was greater with a higher KTAS level than with KTAS level 4 in both the PS-KTAS and TS-KTAS. All areas under the curve of the PS- and TS-KTAS for ICU admission and emergent intervention rate both showed very low discriminant powers. CONCLUSION: Compared to TS-KTAS, PS-KTAS showed a similar or partially better relationship between the KTAS level and the use of critical medical resource. Future research is recommended to improve the matching between the SIRS scoring and each KTAS level to better classify the patient severity status and develop or discover new infection assessment tools that can be applied to KTAS.

Objectives:
The purpose of this study was to classify the users of a university counseling center and define their characteristics using the information from the service application written by them as one of the approaches to improve the efficiency of the center.
Methods:
The participants were a total of 300 users of the university counseling and affiliated psychiatry center in the local science and technology institute. The service application form used in this study contained questions on personal information, overall satisfaction with university life and interpersonal relationships, problem areas and symptoms, depression, anxiety, sleep, family history, suicidal thoughts, experiences of suicide/self-harm attempts, and a functional impairment questionnaire. First, a latent class analysis was performed to classify the layers and define them. Also, a tree-based model was used to confirm the characteristics of the service applications of the suicide/self-harm attempt experience group.
Results:
A total of 5 layers were found to be the most suitable fit. They were named the ‘health concern type,’ ‘relation problem type,’ ‘depression-sleep problem combined type,’ ‘complex problem type,’ and ‘sleep problem type.’ The variable that best discriminates the suicide/selfharm attempt experience group was question 5 of the Patient Health Questionnaire (PHQ-9). The frequency of selection in the impulsivity domain among the problem types and question 9 of the PHQ-9 was followed.
Conclusion
The results of this study indicate that five types of discriminatory interventions are possible based on the characteristics of the service application. The application can thus be used as basic data for increasing service efficiency in university counseling.

Purpose:
The aim of this study was to analyze changes in stump length over time in patients with saphenous vein incompetence treated with cyanoacrylate closure (CAC) or radiofrequency ablation (RFA).
Materials and Methods:
We retrospectively analyzed data collected from patients with saphenous vein incompetence who underwent either CAC or RFA at Seoul National University Hospital between November 2015 and December 2018. The stump lengths were measured using duplex ultrasonography (DUS) within 1 month and 6 months after treatment. The Venous Clinical Severity Score (VCSS) and Aberdeen Varicose Vein Questionnaire (AVVQ) score were used to assess clinical outcomes.
Results:
A total of 97 veins (64 great saphenous veins and 33 small saphenous veins) were analyzed. The stump length was not significantly different between the two groups at <1 month (P=0.311). However, the stump length in the CAC group was significantly longer than that in the RFA group at 6 months (P=0.004).At 6 months, the mean change in stump length was 1.41±2.28 cm in the CAC group and 0.51±0.54 cm in the RFA group (P=0.006). The VCSSs and AVVQ scores significantly improved after both procedures but were not significantly different between the two groups.
Conclusion
DUS at 6 months after treatment showed that the stump length in the CAC group increased more than that in the RFA group. No other factors affected the changes in stump length.

Intravascular fasciitis (IVF) is a very rare disease that is difficult to diagnose preoperatively. Frequently, it can be misdiagnosed as a malignancy or deep vein thrombosis. A 26-year-old man presented with a 6-month history of intermittent cramping pain in the right calf. Duplex ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography were performed in various hospitals. The work-up revealed a hypermetabolic mass in the femoral vein, suggestive of a malignancy, such as leiomyosarcoma. The tumor was located inside the femoral vein with no invasion, and the mass was resected en bloc with the vein wall. Intraoperative frozen section biopsy revealed no malignancy, and the final pathological diagnosis was IVF. Herein, we report a case of IVF and discuss the role of imaging studies in its preoperative diagnosis, with an extensive literature review.
