Purpose: Patients undergoing pancreatoduodenectomy are a high-risk group that requires psychosocial support. This study retrospectively reviewed the prevalence of psychological symptoms in patients undergoing pancreatoduodenectomy for periampullary neoplasm and the psychosocial referral rate after implementing full screening and triage algorithm for administering a distress management protocol based on the integrated supportive care system established in 2010. Materials and Methods: From September 2010 to December 2018, insomnia, anxiety, and depression were screened on the first day of admission (T1) and on the 10th postoperative day (T2). Patients with clinical levels of distress were referred to a mental health clinic for appropriate aftercare. Results: The adherence rate to routine screening was 82.7% (364/440). Among the 364 patients, the prevalence of insomnia, anxiety, and depression increased from 22.0% (T1) to 32.6% (T2, p=0.001), 29.1% to 33.6% (p=0.256), and 18.4% to 27.6% (p=0.001), respectively. Less than 45% of those with psychological symptoms expressed their needs for psychological supportive care. Among those with psychological symptoms at T2, clinical insomnia, anxiety, and depression were detected via in-depth evaluations among 77.2%, 38.1%, and 82.5% of patients, respectively. Patients who had two or more symptoms at T2 had a longer postoperative hospital stay, as compared to those with one or no symptoms (a median of 20.5 days vs. 18.0 days, p=0.006). Psychiatric consultation rate was 72.8% among patients with clinical psychological symptoms, and 74% of the consulted patients completed psychiatric intervention before discharge. Conclusion Over one-third of the patients had psychological symptoms before and after pancreatoduodenectomy. Implementing a routine psychological symptoms screening with a systematic psychiatric referral protocol enhanced surgeons’ responsiveness to patients’ psychological symptoms.

Background: Remdesivir is widely used for the treatment of coronavirus disease 2019 (COVID-19), but controversies regarding its efficacy still remain. Methods: A retrospective cohort study was conducted to evaluate the effect of remdesivir on clinical and virologic outcomes of severe COVID-19 patients from June to July 2020. Primary clinical endpoints included clinical recovery, additional mechanical ventilator (MV) support, and duration of oxygen or MV support. Viral load reduction by hospital day (HD) 15 was evaluated by calculating changes in cycle threshold (Ct) values. Results: A total of 86 severe COVID-19 patients were evaluated including 48 remdesivirtreated patients. Baseline characteristics were not significantly different between the two groups. Remdesivir was administered an average of 7.42 days from symptom onset. The proportions of clinical recovery of the remdesivir and supportive care group at HD 14 (56.3% and 39.5%) and HD 28 (87.5% and 78.9%) were not statistically different. The proportion of patients requiring MV support by HD 28 was significantly lower in the remdesivir group than in the supportive care group (22.9% vs. 44.7%, P = 0.032), and MV duration was significantly shorter in the remdesivir group (average, 1.97 vs. 5.37 days; P = 0.017). Analysis of upper respiratory tract specimens demonstrated that increases of Ct value from HD 1–5 to 11–15 were significantly greater in the remdesivir group than the supportive care group (average, 10.19 vs. 5.36; P = 0.007), and the slope of the Ct value increase was also significantly steeper in the remdesivir group (average, 5.10 vs. 2.68; P = 0.007). Conclusion The remdesivir group showed clinical and virologic benefit in terms of MV requirement and viral load reduction, supporting remdesivir treatment for severe COVID-19.

BACKGROUND: The detection rate of hand-arm vibration syndrome (HAVS) is very low in South Korea compared with other countries. The absence of uniform consensus and guidelines for diagnosing HAVS has been presumed to be one of the reasons. The HAVS has various manifestations including cold intolerance and its severity can be measured using the cold intolerance symptom severity (CISS) questionnaire. This study aimed to determine whether the CISS questionnaire, being used as a screening tool, can aid in the early detection of HAVS. METHODS: A total of 76 male workers with vibration-induced symptoms were enrolled as the final study participants. To compare the CISS score of healthy individuals, 41 men who had never been exposed to local vibration were included in the study. In addition to the former medical questionnaire, the participants answered the CISS questionnaire. A statistical analysis was conducted to identify the association of CISS scores with vibration induced symptom and to determine its cut off value. RESULTS: The reliability of the CISS questionnaire was proven to be good, with a total Cronbach's alpha of 0.922. The mean CISS score of the exposed group increased in every vascular stage [stage 0 = 42.6 (18.5); stage 1 = 59.4 (14.1); and over stage 2 = 60.2 (21.6)]. They were significantly higher than that of the non-exposed group. The result was fairly consistent with those in the sensorineural stage. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under curve (AUC) of 30 were 88.5, 65.3, 76.1, 82.1 and 0.769, respectively. From the result of logistic regression, the adjusted odds ratio of both components increased by the CISS score grouped by 30s. CONCLUSIONS: The self-reported CISS questionnaire, used to measure the degree of cold intolerance, showed high agreement with the Stockholm classification of HAVS. Hence, we recommend the use of this questionnaire to assess the level of cold intolerance among vibration-exposed workers and detect individuals who are at risk of vibration-induced impairment with a cutoff value of 30.

PURPOSE: We compared the posterior capsule rupture (PCR) rate between microscope versus intracameral illumination in phacoemulsification surgery performed by novice ophthalmologists. METHODS: We conducted a retrospective chart review of 300 eyes of 211 patients who underwent phacoemulsification by novice ophthalmologists from March 2012 to October 2017. Novice ophthalmologists (n = 6) were divided into those using microscope illumination (n = 4) and intracameral illumination users (n = 2). The first 50 cataract surgery cases of each novice ophthalmologist were reviewed. The results using a phacoemulsification machine and microscopy were the same. The intraoperative complications and learning curve in each case were evaluated. RESULTS: Phacoemulsifications performed by novice ophthalmologists showed a statistically significant difference in PCR rate between the microscope illumination (19.0%, 38/200) and intracameral illumination (4.0%, 4/100) groups (p = 0.001). The incidence of PCR was reduced to 22%, 18%, 16%, 12%, and 8% per 10 cases in the microscope group, while it was 15% in the first 10 cases and 0% in 50 cases thereafter in the intracameral illumination group. CONCLUSIONS: Novice surgeons had a lower PCR rate during cataract surgery using intracameral illumination than using microscope illumination. Both groups showed a tendency for the PCR to decrease with increasing surgical cases, but the intracameral illumination group showed a shorter learning curve.

BACKGROUND/AIMS: Several epidemiological studies have validated the association of interleukin gene polymorphisms with acute pancreatitis (AP) in different populations. However, there have been few studies in Asian ethnic groups. We aimed to investigate the relationships between inflammatory cytokine polymorphisms and AP as pilot research in a Korean ethnic group. METHODS: Patients who had been diagnosed with AP were prospectively enrolled. DNA was extracted from whole blood, and DNA sequencing was subsequently performed. Single-nucleotide polymorphisms (SNPs) of the interleukin 1β (IL1B), interleukin 1 receptor antagonist (IL1RN), and tumor necrosis factor α (TNFA) genes of patients with AP were compared to those of normal controls. RESULTS: Between January 2011 and January 2013, a total of 65 subjects were enrolled (40 patients with AP vs. 25 healthy controls). One intronic SNP (IL1RN −1129T>C, rs4251961) was significantly associated with the risk of AP (odds ratio, 0.304; 95% confidence interval, 0.095 to 0.967; p = 0.043). However, in our study, AP was not found to be associated with polymorphisms in the promoter regions of inflammatory cytokine genes, including IL1B (−118C>T, c47+242C>T, +3954C/T, and −598T>C) and TNFA (−1211T>C, −1043C>A, −1037C>T, −488G>A, and −418G>A). CONCLUSIONS: IL1RN −1129T>C (rs4251961) genotypes might be associated with a significant increase of AP risk in a Korean ethnic group.

STUDY DESIGN: Retrospective case series. PURPOSE: The purpose of this study was to examine the incidence of neural axis abnormalities and the relevant risk factors in patients with adolescent idiopathic scoliosis (AIS). OVERVIEW OF LITERATURE: The use of preoperative magnetic resonance imaging (MRI) to assess the whole spine in patients with idiopathic scoliosis is controversial, and indications for such MRI evaluations have not been definitively established. However, we routinely use whole-spine MRI in patients with scoliosis who are scheduled to undergo surgical correction. METHODS: A total of 378 consecutive patients with presumed AIS who were admitted for spinal surgery were examined for neural axis abnormalities using MRI. To differentiate patients with normal and abnormal MRI findings, the following clinical parameters were evaluated: age, sex, menarcheal status, rotation angle (using a scoliometer), coronal balance, shoulder height difference, and low back pain. We radiographically evaluated curve type, thoracic or thoracolumbar curve direction, curve magnitude and flexibility, apical vertebral rotation, curve length, coronal balance, sagittal balance, shoulder height difference, thoracic kyphosis, and the Risser sign. RESULTS: Neural axis abnormalities were detected in 24 patients (6.3%). Abnormal MRI findings were significantly more common in males than in females and were associated with increased thoracic kyphosis. However, there were no significant differences in terms of the other measured parameters. CONCLUSIONS: Among the patients with presumed AIS who received preoperative whole-spine MRI, 6.3% had neural axis abnormalities. Males and patients with increased thoracic kyphosis were at a higher risk.

Administration of a hyaluronic acid (HA) filler injection is a common aesthetic procedure widely used for facial soft-tissue augmentation. Owing to their low immunogenicity, hyaluronic acid fillers have rarely been linked with serious long-term adverse effects. Although generally safe, reports of adverse events linked to hyaluronic acid filler injection are increasing following its extensive usage globally. We describe the case of a 33-year-old woman who presented with multiple facial nodules at sites of filler injection. To the best of our knowledge, this is the first reported case of facial pseudocyst related to monophasic hyaluronic acid filler injection, in Korea.

A synchronous incidence of breast cancer and follicular lymphoma (FL) is uncommon. The association between these two conditions could be explained by the antigenic stimulation of the adjacent carcinoma and common genetic background. This study aimed to review the literature, and discuss the etiology and management of synchronous breast cancer and FL. Herein, we presented a case of synchronous ductal carcinoma in situ (DCIS) of the breast and FL involving multiple lymph nodes, including those in both axilla. A 49-year-old woman presented with palpable lumps in both axilla. She underwent lumpectomy, radiotherapy, and hormonal therapy for DCIS, while adjuvant chemotherapy was recommended for the lymphoma. Diagnosis was based on histopathologic analysis, such as excision or biopsy.
