ABSTRACT

Objective@#Systemic lupus erythematosus (SLE) is an autoimmune disease, characterized by the production of autoantibodies and high cholesterol levels. HMG-CoA (3-hydroxy-3-methylglutaryl-coenzyme A) reductase inhibitors have exhibited anti-inflammatory effects in several clinical trials. We conducted this study to evaluate the effect of rosuvastatin on inflammatory responses in lupus-prone mice. @*Methods@#MRL/lpr mice were intraperitoneally injected with rosuvastatin (10 mg/kg, n=4) or vehicle (2% dimethyl sulfoxide, n=4) five times a week from 13 to 17 weeks of age. The serum levels of low-density lipoprotein (LDL) cholesterol and autoantibodies were measured, as well as the urine levels of albumin. Renal tissues were stained for histopathological analysis. Concentrations of key inflammatory cytokines were measured in the serum, and messenger RNA (mRNA) levels in target organs (kidney, spleen, and lymph nodes) were evaluated. @*Results@#Rosuvastatin treatment significantly decreased serum LDL cholesterol concentration in MRL/lpr mice. However, the clinical manifestations and autoantibody titres did not improve with rosuvastatin treatment. In addition, serum inflammatory cytokines and proteinuria did not change. Histopathological analysis of the kidneys revealed no improvement. When assessing the expression of mRNA, treatment with rosuvastatin decreased tumor necrosis alpha and interleukin-17 concentration in spleen and kidney tissue and in the kidneys and lymph nodes of MRL/lpr mice, respectively. @*Conclusion@#Although it can decrease inflammatory cytokines in the lymphoid organs and kidneys of MRL/lpr mice, treatment with rosuvastatin is insufficient to alleviate SLE.

ABSTRACT

Purpose@#The da Vinci single-port (SP) system has been used in various surgical fields, including colorectal surgery.However, limited experience has been reported on its safety and feasibility. This study aims to evaluate the short-term outcomes of SP robotic surgery for the treatment of rectal cancer compared with multiport (MP) robotic surgery. @*Methods@#Rectal cancer patients who underwent curative resection in 2020 were reviewed. A total of 43 patients underwent robotic total mesorectal excision (TME), of which 26 (13 in each group, SPTME vs. MPTME) were included in the case-matched cohort for analysis. Intraoperative and postoperative outcomes and pathological results were compared between the 2 groups. @*Results@#Median tumor height was similar between the 2 groups (SPTME vs. MPTME : 5.9 cm [range, 2.2–9.6 cm] vs. 6.7 cm [range, 3.4–10.0 cm], P = 0.578). Preoperative chemoradiotherapy was equally performed (38.5%). The median estimated blood loss was less (20.0 mL [range, 5.0–20.0 mL] vs. 30.0 mL [range, 20.0–30.0 mL], P = 0.020) and the median hospital stay was shorter (7 days [range, 6–8 days] vs. 8 days [range, 7–9 days], P = 0.055) in the SPTME group. Postoperative complications did not differ (SPTME vs. MPTME : 7.7% vs. 23.1%, P = 0.587). One patient in the SPTME group and 3 in the MPTME group experienced anastomotic leakage. @*Conclusion@#SP robotic TME showed perioperative outcomes similar to MP robotic TME. The SP robotic system can be considered a surgical option for the treatment of rectal cancer. Further prospective randomized trials with larger cohorts are required.

ABSTRACT

Purpose@#Although its efficacy is uncertain, an intraoperative air leak test (ALT) is commonly used to detect mechanical defects following bowel anastomosis. This study aimed to evaluate the efficacy of ALT to detect anastomotic leakage (AL) following rectal excision. @*Methods@#We reviewed our database for patients with rectal cancers who had undergone curative surgery between January 2012 and January 2018. Patients were grouped according to whether or not an ALT was performed. Propensity score analyses were performed to compare outcomes for groups in a 1:1 case-matched cohort. @*Results@#In total, 1,191 patients underwent rectal excision; 438 (219 in each group) formed the case-matched cohort for analysis. The protective stoma rate was 16.0% and 14.6% in the ALT and the no-ALT groups, respectively (P = 0.791). In the ALT group, 2 patients (0.9%) showed a positive result and were treated with rectal tube drainage, resulting in no leakage.There was no significant difference in postoperative AL rate between the groups (ALT group: 4.6% vs. no-ALT group: 4.1%, P > 0.999). @*Conclusion@#ALT played a minimal role in detecting AL following rectal excision. Further studies are warranted to validate our results and clarify whether AL can be prevented with ALT or alternative methods.

ABSTRACT

Objective@#Emergency department-based screening clinic (ED-BSC) is a new concept. It is a multifunctional clinic at the entrance of the emergency department (ED) that serves as a screening center for suspected coronavirus disease 2019 (COVID-19) patients and triaging patients and provides basic emergency treatment. We aimed to analyze the current status of the COVID-19 ED-BSC and determine the factors when assigning suspected COVID-19 patients to the negative pressure isolation rooms (NPIRs) at the ED. @*Methods@#Data of patients who visited the ED-BSC between February 7, 2020, and April 30, 2020, were obtained retrospectively. The data of the patients who underwent the COVID-19 screening test per the standards of the Korea Disease Control and Prevention Agency were analyzed. @*Results@#A total of 1,378 patients who visited the ED-BSC were included in the study. Of these, 1,226 patients were allowed to go home after the COVID-19 screening test, and 152 patients were assigned to the NPIRs. In univariate analysis, factors influencing the allocation of NPIRs were old age, history of overseas travel within the last 14 days, fever and peripheral oxygen saturation. The multivariate regression analysis confirmed that older adults, history of overseas travel within the last 14 days and fever influenced the allocation of patients to NPIRs. @*Conclusion@#This study elucidates the current status of suspected COVID-19 patient visits to an ED-BSC. This study may serve as a basis for the establishment and revision of clinical guidelines for ED-BSC.

ABSTRACT

The indications of hyperbaric oxygen therapy (HBOT) covered by the health insurance in Korea increased to 16 in 2019, which includes acute central retinal artery obstruction within 24 hours of vision loss; anemia due to excessive bleeding, since blood transfusion is impractical; chronic refractory osteomyelitis (Wagner grade ≥3); and intracranial abscess.Current Concepts: HBOT affects the treatment in the primary and secondary mechanisms. According to the Boyle’s law, the primary mechanism is important in treating decompression sickness and intravascular air embolism by decreasing the volume of air bubbles when pressure increases, whereas the secondary mechanism involves hyperoxygenation of the primary mechanism and various effects, such as vasoconstriction, angiogenesis, immune function enhancement, reperfusion injury prevention, antimicrobial action, and gas washout effect, occur. In the past 5 years, domestic HBOT has made significant progress. However, there are many non-therapeutic lowpressure HBOT facilities that are limited by insurance coverage issues, quality equipment management, and medical personnel in HBOT facilities.Discussion and Conclusion: To solve the problem, the introduction of the definition of therapeutic hyperbaric pressure and certification system of HBOT facilities must be initiated. Moreover, the system should be improved so that insurance can be applied for a more indication of HBOT.

ABSTRACT

Objective@#Systemic lupus erythematosus (SLE) is a common chronic autoimmune inflammatory disease. According to recent studies, signaling through Toll-like receptor (TLR) protein, which promotes the production of inflammatory cytokines, leads to the development of SLE. TLR-inhibitory peptide 1 (TIP1) has been newly identified for the treatment of autoimmune diseases. @*Methods@#The effect of TIP1 was analyzed in an SLE mouse model (MRL/lpr). The mice in the control treatment group (n=5) were administered an intravenous injection of phosphate-buffered saline twice weekly, whereas the mice in the TIP1 treatment group (n=6) were administered an intravenous injection of TIP1 (1 nmol/g) twice weekly. MRL/mpj mice (n=5) were selected as normal controls. The mice were injected for 4 weeks between 14 and 18 weeks of age, followed by assays of their spleen, kidneys, lymph nodes, serum, and urine. @*Results@#The antinuclear antibody and inflammatory cytokine (interferon-α) in the serum as well as levels of albumin in the urine of the mice in the TIP1 treatment group had decreased when compared to those of mice in the control treatment group. Kidney inflammation in mice in the TIP1 treatment group was alleviated. The mRNA expression levels of TLR7- or TLR9-related downstream signaling molecules also decreased in all organs of the mice in the TIP1treatment group. @*Conclusion@#Intravenous treatment with TIP1 reduces symptoms and markers of inflammation in MRL/lpr mice. Hence, TIP1 is a promising medication for the treatment of SLE.

ABSTRACT

The midline nasal dermoid cysts are rare congenital neoplasms, which are diagnosed frequently in childhood. Masses are often noticeable at birth gaining size over time with recurrent infections and usually arise from the nasal cavity or lower 1/3 of the nasal dorsum. CT scan as the primary investigation is helpful to determine accurately the size and extent of the lesion as well as the integrity of adjacent bony structures. MRI scan is recommended to rule out an intracranial extension or sinus tracts. Treatment of choice is the complete surgical excision preserving the cyst wall. Here in, we present an unusual case of nasofrontal dermoid cyst in a 19-year-old boy without radiographic evidence of transcranial extension. In this case, we surgically removed nasofrontal dermoid cyst via transcolumellar approach. We also corrected saddle nose deformity after mass removal. Therefore, in this case, we experienced a successful case in which the nasofrontal dermoid cyst was totally removed without facial scar and deformity.

ABSTRACT

OBJECTIVE: The mismatch in the demand and supply of emergency medical resources has been a constant issue in Korean emergency departments (EDs). This study analyzed the characteristics and actual utilization of medical bed resources in these EDs. METHODS: The emergency department utilization (EDU) rate was calculated using the Emergency Medical Resource Information System (EMRIS) on the available beds in EDs from April 2014 to January 2015. The EDU rate was analyzed according to the season, day of the week, time of day, and ED type. Furthermore, the ratio between the maximum and minimum EDU rates was also compared between the regions. RESULTS: A total of 14,889,750 data points were included. The EDU rate was relatively high during winter and on Sundays, and was highest between 20:00 and 22:00. The ratio between the maximum and minimum EDU rates according to the time of day was highest in Gyeongbuk (5.4) and lowest in Daegu (1.4). Moreover, the EDU rate according to the ED type was highest in the regional emergency medical center (66.7%). CONCLUSION: Significant differences were observed in the EDU rates according to the season, day of the week, time of the day, region, and ED type. Therefore, EMRIS should allocate resources based on the data on both the hospital and regional characteristics.

ABSTRACT

PURPOSE: After trauma and surgery, upper gastrointestinal bleeding (UGIB) is the most common condition that can require massive transfusion (MT). The present study aimed to analyze and compare the prognostic performance of the Glasgow-Blatchford (GB), pre-endoscopy Rockall (PER), and modified early warning (MEW) scores for predicting MT in patients with unstable UGIB. MATERIALS AND METHODS: This retrospective observational study included patients with UGIB from March 2016 to February 2018. Receiver operating characteristics analysis was performed to examine the prognostic performance of the GB, PER, and MEW scoring systems. Logistic regression analysis was used to identify independent risk factors for MT, after adjusting for relevant covariates. The primary outcome was MT. RESULTS: Of the 484 included patients with unstable UGIB, 19 (3.9%) received an MT. The areas under the curves (AUCs) of the GB, PER, and MEW scores for MT were 0.577 [95% confidence interval (CI), 0.531–0.621], 0.570 (95% CI, 0.525–0.615), and 0.767 (95% CI, 0.727–0.804), respectively. The AUC of the MEW score was significantly different from those of the GB and PER scores. In multivariate analysis, MEW score was independently associated with MT in patients with unstable UGIB (odds ratio, 1.495; 95% CI, 1.100–2.033; p=0.010). CONCLUSION: In unstable UGIB patients, MEW score had the best prognostic performance for MT among three scoring systems.

ABSTRACT

Hamartomas are non-neoplastic malformations or congenital errors of tissue development. Hamartoma is composed by an excessive growth of mature tissue present in wrong proportions and abnormal arrangements. The lesion usually presents as a submucosal mass with ill-defined margins. Hamartoma occurs in all areas of the body, especially in the liver, spleen, kidney and lung. However, hamartoma is very rare in the head and neck. Presenting symptoms of hamartoma are typically vague and nonspecific. Treatment of hamartomas consists of adequate surgical excision. We present a 59 year-old male patient who presented with submental swelling. Malignancy could not be ruled out with preoperative radiologic examination, so surgical excision was planned. The mass was excised with transcervical approach. Histopathologic examination has confirmed the mass as a mucinous gland adenomatoid hamartoma.

ABSTRACT

BACKGROUND AND OBJECTIVES: Drug-induced sedation endoscopy (DISE) has recently gained popularity among otolaryngologists because it can provide direct information of upper airway obstruction in patients with obstructive sleep apnea (OSA). In that regard, we examined how DISE examination affected the decision of clinician's treatment plan and the consequent patient's compliance in OSA patients. SUBJECTS AND METHOD: All enrolled patients were classified into two groups according to the method of upper airway evaluation employed: a physical examination only group and a physical examination combined with DISE group. The clinician's treatment plan was categorized into the following four groups: sleep surgery, positive airway pressure, oral appliance, and sleep surgery combined with oral appliance. The change of patient's compliance was also evaluated. RESULTS: There were several differences in how DISE evaluation affected the decision of clinician's treatment plan and patient's compliance between the two groups. The rate for sleep surgery fell from 69.6% to 15.9%; on the other hand, the rate for positive airway pressure, oral appliance and sleep surgery combined with oral appliance all increased from 13.0% to 36.2%, 14.5% to 26.6%, and 2.9% to 21.3%, respectively. The patient's compliance also changed after DISE evaluation: sleep surgery, positive airway pressure, oral appliance and sleep surgery combined with oral appliance all increased from 78.1% to 87.9%, 16.7% to 76.0%, 25.0% to 87.3%, and 50.0% to 91.03%, respectively. CONCLUSION: We found that DISE examination influences the decision of clinician's treatment plan and patient's compliance. We suggest additional cohort studies to confirm these findings.

ABSTRACT

Sebaceous carcinoma of the salivary gland is an extremely unordinary malignancy occurring mainly in the parotid gland. Sebaceous carcinoma arising in the submandibular gland is exceptional and only three cases have been reported in the literature. We herein present a unique case of sebaceous carcinoma of the submandibular gland, the first to be reported in literature in South Korea. An 85-year-old man visited our hospital complaining of a progressively enlarging submandibular mass with tenderness and ipsilateral facial palsy. We performed a wide excision of the mass with superficial parotidectomy and modified neck dissection. Microscopic and immunohistochemical examinations demonstrated sebaceous carcinoma of low grade differentiation. Further adjuvant radiotherapy was rejected and the patient was followed up for five months. The optimal treatment of sebaceous carcinoma of the salivary gland is still not established due to the rarity of the disease. When more cases are reported, the clinicopathologic characteristics will be better understood.

ABSTRACT

OBJECTIVES: Pediatric sleep-disordered breathing (SDB) is a common debilitating disorder that can adversely affect the attention and academic performance of school-age children. Unfortunately, only a few studies have examined the effect of SDB treatment on attention in pediatric populations. Therefore, the aim of this study was to prospectively investigate the effect of SDB treatment on attention in children. METHODS: This study consecutively enrolled SDB children with adenotonsillar hypertrophy. All subjects underwent standard-of-care treatment (adenotonsillectomy or close observation) and were evaluated using a computerized comprehensive attention test at the initial visit. Comprehensive attention tests consisted of both sustained and divided attention tasks. Each completed task was assigned an attention score, which was based on the number of omission or commission errors. The comprehension attention test was repeated 1 year later. RESULTS: A total of 171 children who underwent adenotonsillectomy and 32 children who did not undergo adenotonsillectomy were included in this study. At baseline, there was no significant difference according to the score of all type comprehension attention tests between children in the adenotonsillectomy group and in the observation group. One year after treatment, children in the adenotonsillectomy group had significantly improved scores in all attention tasks. Children in the observation group had only significant improvement in omission errors on sustained attention tasks. Meanwhile, the attention score based on commission errors of divided attention tasks was significantly worse than at baseline for those. CONCLUSION: Our study showed that adenotonsillectomy may be helpful in improving attention in children with SDB.

ABSTRACT

Removing of foreign bodies in the external auditory canal is commonly observed in the otorhinolaryngologic field. Sometimes the size of some materials might change after being embedded in the canal; in such situation, debulking procedures are usually performed to reduce the size of the materials stuck there. But if it is hard to shrink the materials' size, we should consider other procedures. Here we present a minimized procedure utilized to remove nettlesome fragments of industrial cement via 3-dimensional reconstruction of temporal bone computed tomography and partial canaloplasty through transcanal approach.

ABSTRACT

BACKGROUND AND OBJECTIVES: Recently, mandibular advancement device (MAD) has been used widely used for the treatment of obstructive sleep apnea (OSA) because it can effectively reduce the collapsibility of upper airway during sleep. Although MAD is widely prescribed by otorhinolaryngologists, several studies described its complications arising from the anterior placement of the mandible with long-term use. However, there is still a lack of studies on long-term complications in Korean patients. SUBJECTS AND METHOD: Retrospectively, we included a total of 57 OSA patients in the study. In this study, all enrolled OSA patients had used MAD over two years with more than 4 hours/day. Dental consulting and cephalometric analysis were conducted to identify the change of dental and skeletal findings at two different times (baseline and after 2 year). RESULTS: The dental findings showed that the overbite and overjet were significantly decreased. Additionally, the proclination of the lower incisors were increased significantly, whereas there was no significant change on the retroclination of the upper incisors. Three patients showed a change of malocclusion type. On the analysis of skeletal findings, we found a significant increase in the sella turcica central point-nasion-supramental point angle and a decrease in the subspinal point-nasion-supramental point angle. Moreover, the anterior lower facial height and anterior facial height were significant increased. CONCLUSION: Consistent with Western studies, our findings suggest that the long-term use of MAD could induce changes in dental and skeletal morphologies in Korean OSA patients. Therefore, clinicians should thoroughly evaluate potential changes in dental and skeletal morphologies when they prescribe MAD to patients with OSA.

ABSTRACT

BACKGROUND: This study aimed to present our 5-year experience of extracorporeal cardiopulmonary resuscitation (ECPR) performed by emergency physicians. METHODS: We retrospectively analyzed 58 patients who underwent ECPR between January 2010 and December 2014. The primary parameter analyzed was survival to hospital discharge. The secondary parameters analyzed were neurologic outcome at hospital discharge, cannulation time, and ECPR-related complications. RESULTS: Thirty-one patients (53.4%) were successfully weaned from extracorporeal membrane oxygenation, and 18 (31.0%) survived to hospital discharge. Twelve patients (20.7%) were discharged with good neurologic outcomes. The median cannulation time was 25.0 min (interquartile range 20.0-31.0 min). Nineteen patients (32.8%) had ECPR-related complications, the most frequent being distal limb ischemia. Regarding the initial presentation, 52 patients (83.9%) collapsed due to a cardiac etiology, and acute myocardial infarction (33/62, 53.2%) was the most common cause of cardiac arrest. CONCLUSIONS: The survival to hospital discharge rate for cardiac arrest patients who underwent ECPR conducted by an emergency physician was within the acceptable limits. The cannulation time and complications following ECPR were comparable to those found in previous studies.

ABSTRACT

OBJECTIVE: We investigated the association between lactate clearance or serum lactate levels and neurologic outcomes or in-hospital mortality in cardiac arrest survivors who were treated with targeted temperature management (TTM). METHODS: A retrospective analysis of data from cardiac arrest survivors treated with TTM between 2012 and 2015 was conducted. Serum lactate levels were measured on admission and at 12, 24, and 48 hours following admission. Lactate clearance at 12, 24, and 48 hours was also calculated. The primary outcome was neurologic outcome at discharge. The secondary outcome was in-hospital mortality. RESULTS: The study included 282 patients; 184 (65.2%) were discharged with a poor neurologic outcome, and 62 (22.0%) died. Higher serum lactate levels at 12 hours (odds ratio [OR], 1.157; 95% confidence interval [CI], 1.006 to 1.331), 24 hours (OR, 1.320; 95% CI, 1.084 to 1.607), and 48 hours (OR, 2.474; 95% CI, 1.459 to 4.195) after admission were associated with a poor neurologic outcome. Furthermore, a higher serum lactate level at 48 hours (OR, 1.459; 95% CI, 1.181 to 1.803) following admission was associated with in-hospital mortality. Lactate clearance was not associated with neurologic outcome or in-hospital mortality at any time point after adjusting for confounders. CONCLUSION: Increased serum lactate levels after admission are associated with a poor neurologic outcome at discharge and in-hospital mortality in cardiac arrest survivors treated with TTM. Conversely, lactate clearance is not a robust surrogate marker of neurologic outcome or in-hospital mortality.
