Xanthomas are benign lesions characterized by the aggregation of lipid-laden histiocytes and foamy cells within tissues. Intraosseous xanthomas (IOXs), especially those in the jaw bone, are rare, with only around 50 cases documented. This case report describes an IOX located at an osteotomy site in the mandible during sagittal split ramus osteotomy (SSRO). Preoperative radiographs revealed a heterogenic radiolucent-radiopaque lesion in the right ramus. After meticulous curettage of the lesion, proximal and distal segments were fixed in the semi-rigid plates and screws. At the one-year followup, radiographs showed excellent bony union between proximal and distal segments, with no significant interval change. IOXs rarely occur in the jaw.However, their predilection for the posterior mandible suggests that such lesions can be encountered during orthognathic surgery. This report demonstrates the feasibility of performing SSRO directly through the lesion with concurrent curettage without compromising surgical outcomes. This case will contribute to the limited literature on IOX of the jaw bone and its treatment via SSRO as a feasible surgical option in concomitant orthognathic surgery.

OBJECTIVE:
Acupotomy is a modern acupuncture method that includes modern surgical methods. Since acupotomy is relatively more invasive than filiform acupuncture treatment, it is important to establish the safety profile of this practice. To justify further large-scale prospective observational studies, this preliminary study was performed to assess the feasibility of the approach and investigate the safety profile and factors potentially associated with adverse events (AEs).
METHODS:
This was a prospective pilot study that assessed the feasibility of a large-scale forthcoming safety study on acupotomy treatment in a real-world setting. The feasibility (call response rate, drop-out rate, response rate for each variable and recruitment per month) and safety profile (incidence, type, severity and causality of AEs, and factors potentially associated with AEs) were measured.
RESULTS:
A total of 28 participants joined the study from January to May 2018. A follow-up assessment was achieved in 258 (1185 treatment points) out of 261 sessions (1214 treatment points). The response rate via telephone on the day after treatment was 87.3%. There were 8 systemic AEs in all the sessions (8/258; 3.11%) and 27 local AEs on the total points treated (27/1185; 2.28%). Severe AEs did not occur. Total AE and local AE occurrence were associated with blade width and the number of needle stimulations per treatment point.
CONCLUSION:
The findings suggest that it could be feasible to analyze the safety of acupotomy in a real-world setting. Moreover, the primary data on some relevant AEs could be determined. We are planning large-scale prospective studies based on these findings.

Purpose:
Proper use of antibiotics during emergency abdominal surgery is essential in reducing the incidence of surgical site infection. However, no studies have investigated the type of antibiotics and duration of therapy in individuals with abdominal trauma in Korea. We aimed to investigate the status of initial antibiotic therapy in patients with solitary abdominal trauma.
Methods:
From January 2015 to December 2015, we retrospectively analyzed the medical records of patients with solitary abdominal trauma from 17 institutions including regional trauma centers in South Korea. Both blunt and penetrating abdominal injuries were included. Time from arrival to initial antibiotic therapy, rate of antibiotic use upon injury mechanism, injured organ, type, and duration of antibiotic use, and postoperative infection were investigated.
Results:
Data of the 311 patients were collected. The use of antibiotic was initiated in 96.4% of patients with penetrating injury and 79.7% with blunt injury. Initial antibiotics therapy was provided to 78.2% of patients with solid organ injury and 97.5% with hollow viscus injury. The mean day of using antibiotics was 6 days in solid organ injuries, 6.2 days in hollow viscus. Infection within 2 weeks of admission occurred in 36 cases. Infection was related to injury severity (Abbreviated Injury Scale of >3), hollow viscus injury, operation, open abdomen, colon perforation, and RBC transfusion. There was no infection in cases with laparoscopic operation. Duration of antibiotics did not affect the infection rate.
Conclusion
Antibiotics are used extensively (84.2%) and for long duration (6.2 days) in patients with abdominal injury in Korea.

Background/Aims:
Pheochromocytoma and paraganglioma (PPGL) are catecholamine-producing tumors that can cause blood pressure (BP) elevation and cardiovascular complications. Clinical presentation of these tumors may be changed through widespread use of imaging studies, which enables detection of PPGLs before onset of symptoms. We investigated clinical profiles of patients with surgically resected PPGLs.
Methods:
From 2005 to 2017, 111 consecutive patients with surgically resected PPGLs in two tertiary hospitals in Korea were studied.
Results:
Mean age was 52 ± 16 years, 57 patients (51.4%) were male and 54 (48.6%) were hypertensive. Twenty-nine PPGLs (26.1%) were extra-adrenal paragangliomas. Sixteen (14.4%) and seven patients (6.3%) (Group 1, n = 23) were diagnosed during work-up of hypertension and transient cardiomyopathy respectively, and the remainder (Group 2, n = 88) were incidentalomas detected during routine abdominal imaging. Patients in the Group 1 were younger and more frequently symptomatic, and had higher BPs, heart rates and levels of urinary catecholamines than those in the Group 2. Paragangliomas were less frequent and secretion of epinephrine and metanephrine was more predominant in the Group 1 than in Group 2. After the surgical resections, 18.2% of patients still needed antihypertensive medications.
Conclusions
Out of 111 patients with surgically resected PPGLs, 88 (79.3%) were diagnosed as incidentalomas. Seven patients presented with transient cardiomyopathy and 16 with hypertension. Tumor location and secretion of catecholamine may vary depending on the presence of symptoms.

Background:
Accurate molecular classification of breast core needle biopsy (CNB) tissue is important for determining neoadjuvant systemic therapies for invasive breast cancer. The researchers aimed to evaluate the concordance rate (CR) of molecular subtypes between CNBs and surgical specimens.
Methods:
This study was conducted with invasive breast cancer patients who underwent surgery after CNB at Seoul St. Mary’s Hospital between December 2014 and December 2017. Estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and Ki67 were analyzed using immunohistochemistry. ER and PR were evaluated by Allred score (0–8). HER2 was graded from 0 to +3, and all 2+ cases were reflex tested with silver in situ hybridization. The labeling index of Ki67 was counted by either manual scoring or digital image analysis. Molecular subtypes were classified using the above surrogate markers.
Results:
In total, 629 patients were evaluated. The CRs of ER, PR, HER2, and Ki67 were 96.5% (kappa, 0.883; p<.001), 93.0% (kappa, 0.824; p<.001), 99.7% (kappa, 0.988; p<.001), and 78.7% (kappa, 0.577; p<.001), respectively. Digital image analysis of Ki67 in CNB showed better concordance with Ki67 in surgical specimens (CR, 82.3%; kappa, 0.639 for digital image analysis vs. CR, 76.2%; kappa, 0.534 for manual counting). The CRs of luminal A, luminal B, HER2, and triple negative types were 89.0%, 70.0%, 82.9%, and 77.2%, respectively.
Conclusions
CNB was reasonably accurate for determining ER, PR, HER2, Ki67, and molecular subtypes. Using digital image analysis for Ki67 in CNB produced more accurate molecular classifications.

PURPOSE: A task force appointed by the Korean Society of Acute Care Surgery reviewed previously published guidelines on antibiotic use in patients with abdominal injuries and adapted guidelines for Korea. METHODS: Four guidelines were assessed using the Appraisal of Guidelines for Research and Evaluation II instrument. Five topics were considered: indication for antibiotics, time until first antibiotic use, antibiotic therapy duration, appropriate antibiotics, and antibiotic use in abdominal trauma patients with hemorrhagic shock. RESULTS: Patients requiring surgery need preoperative prophylactic antibiotics. Patients who do not require surgery do not need antibiotics. Antibiotics should be administered as soon as possible after injury. In the absence of hollow viscus injury, no additional antibiotic doses are needed. If hollow viscus injury is repaired within 12 hours, antibiotics should be continued for ≤ 24 hours. If hollow viscus injury is repaired after 12 hours, antibiotics should be limited to 7 days. Antibiotics can be administered for ≥7 days if hollow viscus injury is incompletely repaired or clinical signs persist. Broad-spectrum aerobic and anaerobic coverage antibiotics are preferred as the initial antibiotics. Second-generation cephalosporins are the recommended initial antibiotics. Third-generation cephalosporins are alternative choices. For hemorrhagic shock, the antibiotic dose may be increased twofold or threefold and repeated after transfusion of every 10 units of blood until there is no further blood loss. CONCLUSION: Although this guideline was drafted through adaptation of other guidelines, it may be meaningful in that it provides a consensus on the use of antibiotics in abdominal trauma patients in Korea.

OBJECTIVE: To investigate the effect of physical therapy (PT) intervention on spasticity in patients with cerebral palsy (CP), and to assess the degree of deterioration of spasticity when regular PT is interrupted in those patients. METHODS: We recruited 35 children with spastic CP who visited our hospital for PT, and whose Modified Tardieu Scale (MTS) scores were serially recorded including before and after a 10-day public holiday time frame period. The outcome measures were the angle of range of motion (ROM) of dorsiflexion of the ankle joint (R1 and R2) in the knee flexion and extension positions as assessed using the MTS. RESULTS: The range of dorsiflexion of the ankle joint (R1 and R2) after the holiday period was significantly decreased as compared with that measured ROM noted before the holiday period, regardless of the knee position, age, or gross motor function. The dynamic component of the MTS (R2–R1) showed a slight decrease in the knee flexion position. CONCLUSION: Interruption of regular PT aggravated spasticity and decreased ankle joint ROM in children with spastic CP. Our findings suggest that regular PT in the care continuum for children with CP is crucial for the maintenance of ROM in the spastic ankle joints.

PURPOSE: Nutritional therapy (NT), such as enteral nutrition (EN) or parenteral nutrition (PN), is essential for the malnourished patients. Although the complications related to NT has been well described, multicenter data on symptoms in the patients with receiving NT during hospitalization are still lacking. METHODS: Nutrition support team (NST) consultations, on which NT-related complications were described, were collected retrospectively for one year. The inclusion criteria were patients who were (1) older than 18 years, (2) hospitalized, and (3) receiving EN or PN at the time of NST consultation. The patients' demographics (age, sex, body mass index [BMI]), type of NT and type of complication were collected. To compare the severity of each complication, the intensive care unit (ICU) admission, hospital stay, and type of discharge were also collected. RESULTS: A total of 14,600 NT-related complications were collected from 13,418 cases from 27 hospitals in Korea. The mean age and BMI were 65.4 years and 21.8 kg/m2. The complications according to the type of NT, calorie deficiency (32.4%, n=1,229) and diarrhea (21.6%, n=820) were most common in EN. Similarly, calorie deficiency (56.8%, n=4,030) and GI problem except for diarrhea (8.6%, n=611) were most common in PN. Regarding the clinical outcomes, 18.7% (n=2,158) finally expired, 58.1% (n=7,027) were admitted to ICU, and the mean hospital days after NT-related complication were 31.3 days. Volume overload (odds ratio [OR]=3.48) and renal abnormality (OR=2.50) were closely associated with hospital death; hyperammonemia (OR=3.09) and renal abnormality (OR=2.77) were associated with ICU admission; “micronutrient and vitamin deficiency” (geometric mean [GM]=2.23) and volume overload (GM=1.61) were associated with a longer hospital stay. CONCLUSION: NT may induce or be associated with several complications, and some of them may seriously affect the patient's outcome. NST personnel in each hospital should be aware of each problem during nutritional support.
