ABSTRACT

Purpose@#Sepsis is one of the most common causes of death after surgery. Several conventional scoring systems have been developed to predict the outcome of sepsis; however, their predictive power is insufficient. The present study applies explainable machine-learning algorithms to improve the accuracy of predicting postoperative mortality in patients with sepsis caused by peritonitis. @*Methods@#We performed a retrospective analysis of data from demographic, clinical, and laboratory analyses, including the delta neutrophil index (DNI), WBC and neutrophil counts, and CRP level. Laboratory data were measured before surgery, 12–36 hours after surgery, and 60–84 hours after surgery. The primary study output was the probability of mortality.The areas under the receiver operating characteristic curves (AUCs) of several machine-learning algorithms using the Sequential Organ Failure Assessment (SOFA) and Simplified Acute Physiology Score (SAPS) 3 models were compared.‘SHapley Additive exPlanations’ values were used to indicate the direction of the relationship between a variable and mortality. @*Results@#The CatBoost model yielded the highest AUC (0.933) for mortality compared to SAPS3 and SOFA (0.860 and 0.867, respectively). Increased DNI on day 3, septic shock, use of norepinephrine therapy, and increased international normalized ratio on day 3 had the greatest impact on the model’s prediction of mortality. @*Conclusion@#Machine-learning algorithms increase the accuracy of predicting postoperative mortality in patients with sepsis caused by peritonitis.

ABSTRACT

Background@#Subscapularis tendon insertion at the first facet has separate layers (deep and superficial). The purpose of this study is to evaluate postoperative clinical outcomes and radiological healing according to each layer of detachment in the first facet involving subscapularis tendon tear. @*Methods@#Eighty-three patients who underwent arthroscopic repair due to First facet involving the scapularis tendon tear accompanying small to medium sized posterosuperior cuff tear were classified into three groups (group A: deep layer partial detachment, group B: deep layer complete detachment, but no superficial layer detachment, and group C: deep layer and superficial layer complete detachment). Subscapularis tendon healing was evaluated using computed tomography arthrogram and clinical result was evaluated using American Shoulder and Elbow Surgeons (ASES) shoulder score, Constant score and University of California Los Angeles (UCLA) shoulder score. @*Results@#Retear rate of the subscapularis tendon was 2.2%, 18.2%, and 33.3% in group A, group B, and group C, respectively. These rates showed statistically significant difference among the three groups, which were classified by deep and superficial layer detachment in the first facet (p=0.003). Group A showed significant difference in subscapularis tendon healing compared with group B and group C (p=0.018 and p<0.001, respectively), but there was no statistical difference between group B and group C (p=0.292). Regarding clinical outcomes, there was no significant difference among three groups in ASES and UCLA score at final follow-up (p=0.070 and p=0.106, respectively). @*Conclusions@#Complete detachment of deep layer may be related with retear occurrence regardless with detachment of superficial layer, but clinical outcome may not be related with each layer detachment in the first facet involving subscapularis tendon tear.

ABSTRACT

Background@#The treatment of keloids is both challenging and controversial. Until now, there is no definitive treatment modality for keloids. To determine the efficacy and safety of an intralesional cocktail therapy, including bleomycin compared to corticosteroid injection method on the treatment of keloid scars. @*Methods@#A retrospective chart review was performed for 35 patients diagnosed with keloids. The cocktail therapy regimen consisted of bleomycin, 1% lidocaine, verapamil, and triamcinolone, which was further diluted with 1 mL of normal saline. In group B, 1mL of triamcinolone acetonide was injected into the lesion. Results for a total of 35 patients included in this study were evaluated according to their therapeutic responses and complications six months after the last session. @*Results@#Analyzing the outcomes of the patients treated with a cocktail regimen (group A), it was found that 87% showed favorable therapeutic responses (scar thickness <50%). In group B, 58% of patients showed favorable therapeutic responses. No major complications were observed in both groups. @*Conclusions@#High therapeutic response rates without major complications were identified in this study, suggesting that cocktail therapy with bleomycin can be considered a safe and effective treatment modality for keloid scars.

ABSTRACT

Purpose@#Meckel diverticulum (MD), caused by an obliteration defect of the omphalomesenteric duct, is one of the most common congenital anomalies of small intestines. The objective of this study was to review surgical outcomes of MD and evaluate the feasibility of minimally invasive surgery (MIS) in MD. @*Methods@#We performed a retrospective analysis of the medical records of patients who underwent diverticulectomy for MD at 6 Hallym University-affiliated hospitals between January 2008 and December 2017. All patients underwent either open surgery or MIS. Patients who underwent MIS were subdivided into laparoscopic only diverticulectomy (LOD) or laparoscopic-assisted diverticulectomy (LAD). @*Results@#Of 64 patients, 21 underwent open surgery and 43 underwent MIS. Time to flatus, time to soft food intake, and length of hospital stay were shorter in the MIS group than in the open surgery group (P = 0.047, P = 0.005, and P = 0.015, respectively). Among patients who underwent MIS, the time to flatus and time to soft food intake were longer in the LAD group than in the LOD group (0.3 and 0.9 days, respectively). Multivariate analysis showed that old age and preoperative ileus were independent predictors of complications (P = 0.030 and P = 0.013, respectively). Operation type (open surgery, LOD, or LAD) was not associated with complications. @*Conclusion@#The present study showed that MIS is associated with quicker recovery without increasing complications.Therefore, MIS may be a safe alternative to open surgery for MD. An old age and preoperative ileus were associated with a risk of postoperative complications.

ABSTRACT

BACKGROUND AND OBJECTIVES: Auditory brainstem response (ABR) can be utilized to verify the hearing threshold and determine the existence of retrocochlear pathology in sudden deafness. However, little is known about the significance of ABR characteristics as a prognostic factor in sudden deafness. The purpose of this study is to evaluate which characteristics of ABR is associated with the prognosis of sudden deafness. SUBJECTS AND METHOD: We studied patients who were diagnosed with unilateral sudden deafness from January 2017 to May 2018. ABR results of click stimuli at 90 dB nHL were analyzed by the latency of wave I, III, and V. RESULTS: A total of 113 patients (55 men and 58 women) participated in the study. Hearing recovery was observed in 94 cases (83.2%). The absolute latency of wave I, III, and V was prolonged in the affected ears when compared with the unaffected ears. Hearing improvement was only correlated to the interaural latency delay of wave I (Pearson's r=−0.278, p<0.05). Prolonged interaural latency delay was noted from complete toward slight hearing recovery group. When the hearing outcome was evaluated by the interaural latency delay of wave I at 0.2 ms, the result of under 0.2 ms was significantly better than that over 0.2 ms and no visible wave I. CONCLUSION: Prolonged interaural delay of wave I over 0.2 ms and no visible wave I in ABR showed worse hearing outcome in sudden deafness. This finding may provide ABR as a potential prognostic indicator in sudden deafness.

ABSTRACT

PURPOSE: Surgeons may be uncertain about the optimal timing of appendectomy to decrease complications, especially for complicated appendicitis. The aim of the study was to compare clinical outcomes between early and late surgery for complicated appendicitis. METHODS: A prospectively maintained database of complicated appendicitis was queried. Elective interval surgery (EIS) group and early surgery (ES) were matched with propensity score and marked with a prefix ‘p.’ Patient characteristics and surgical outcomes were compared. RESULTS: The propensity score-matched EIS group had a lower chance to underwent ileo-cecectomy or right hemicolectomy (1.5% vs. 6.9%, P = 0.031), a tendency of lower rate of postoperative complication (6.9% vs. 13.7%, P = 0.067), a lower rate of wound infection (1.5% vs. 8.4%, P = 0.010), and shorter postoperative hospital stay (3.72 days vs. 5.82 days, P < 0.001) than the propensity score-matched ES group. Multivariate analysis showed that delayed surgery for more than 48 hours or urgent surgery due to failure of EIS and open conversion were independent risk factors for postoperative complications (P = 0.001 and P = 0.025, respectively). In subgroup analysis, high American Society of Anesthesiologists physical status classification and distant abscess or generalized ascites in initial CT increased the risk of failure of EIS. CONCLUSION: EIS can be a useful option for selected adult patients with complicated appendicitis.

ABSTRACT

Depression of facial contour after parotidectomy is still challenging to many of surgeons. A 68-year-old man presented with a 4-month history of a painless swelling in both parotid area. The mass was multiple and fixed at the parotid region. We conducted a parotid duct preserving bilateral superficial parotidectomy by one-stage operation to remove the multiple tumors. A lazy S incision was made in both preauricular area and the peripheral branches of the facial nerve were identified using surgical landmark. After dissecting the branches of the facial nerve and parotid duct, main parotid duct was preserved but only small fine ductules from the superficial lobe were ligated. Parotid gland was excised from its anterior aspect with about 1 cm of normal parotid tissue margin. The patient was followed up for 6 years to evaluate postoperative parotid gland function and the computed tomography (CT) was taken. Patient was satisfied with no significant complication such as sunken changes in facial contour, facial nerve function. As far as we know, it is the first study to compare long-term soft tissue contours of soft tissue of duct preserving superficial parotidectomy with duct sacrificing superficial parotidectomy by means of CT findings.

ABSTRACT

PURPOSE: Laparoscopic adhesiolysis is increasingly used to treat patients with small bowel obstruction (SBO), however, its safety of laparoscopic surgery(LS) with bowel resection in SBO is unclear. The purpose of the present study was to compare the perioperative outcomes of LS with those of open surgery (OS) for SBO and to evaluate the risk factors of 30-day postoperative morbidity and recurrence. METHODS: We retrospectively reviewed medical records of patients who had been diagnosed with SBO and underwent surgery at four Hallym-University-affiliated hospitals between January 2013 and December 2016. The rates of 30-day postoperative complications and recurrence were compared between groups using univariate and multivariate analysis. Propensity score matching was performed to compare the outcome. RESULTS: A total of 117 patients with SBO were included in the present study, of which 86 underwent OS and 31 underwent LS. Time to water intake, time to soft diet, and postoperative hospital stay were significantly shorter in the LS group (p=0.002, 0.003, and 0.027, respectively). The complication (p=0.249) and recurrence rate (p=0.679) were similar between the two group. Propensity score matching analysis demonstrated that laparoscopic surgery showed quicker recovery and similar complication and recurrence rate. In multivariate analysis, LS was not associated with either complications (p=0.806) or recurrence (p=0.956). CONCLUSION: LS is associated with several perioperative advantages for the treatment of SBO without affecting the risk of 30-day postoperative complications or recurrence. Therefore LS can be a safe and feasible option for treating SBO.

ABSTRACT

BACKGROUND: Inverted nipples can pose aesthetic and functional problems, especially for young women. The objectives of inverted nipple correction are both sufficient aesthetic projection of the nipple and postoperative functional preservation of the lactiferous ducts. Recurrence of nipple inversion is still an unsolved problem in many cases. We present a new nipple suspension technique using nipple- and areola-based dermal flaps for correcting inverted nipples and preserving the lactiferous duct to minimize the risk of recurrence. METHODS: We corrected six inverted nipples in three patients, which were classified as grade II using the Han and Hong classification of nipple inversion. The anteroposterior and lateral medical-quality photographs of the respective patients were identified for nipple protrusion and recurrence during a 6-month follow-up period to evaluate aesthetical goal and assess the sensitivity of the nipple to confirm preservation of the main lactiferous ducts. Surgical details are described within the main text. RESULTS: Preoperative and postoperative photography revealed good nipple protrusion during the 6-month follow-up period without any complications such as skin necrosis and recurrence. We were unable to directly identify breast-feeding function because all three patients were young and unmarried women. However, we assumed preservation of the main lactiferous duct since no nipple sensory change was identified in the postoperative examination when compared with the preoperative examination. CONCLUSIONS: With this method, we were able to confirm the hardness of the column and minimize the injury of the main lactiferous duct.

ABSTRACT

PURPOSE: The purpose of this study was to compare the clinical and radiological results of patients with metacarpal midshaft fracture following surgery using either intramedullary K-wire nailing or internal fixation of plates. MATERIALS AND METHODS: This study was conducted with 39 metacarpal midshaft fracture patients between October 2008 and September 2012. Of these 39 patients, 15 patients underwent intramedullary K-wire nailing and 24 patients underwent internal fixation of metal plates. We analyzed bone union time and final posterior angulation radiologically and the range of motion, grip power, and quick-disabilities of the arm, shoulder and hand (DASH) scores, visual analogue scale (VAS) score clinically. RESULTS: Bone union was observed in all cases and bone union times were not significantly different between the two surgical methods. The final follow-up radiographs showed statistically significant differences in posterior angulation, which was 14°, on average, among the patients who underwent intramedullary K-wire nailing and 5°, on average, among the patients who underwent internal fixation of plates. No significant differences were found for the range of joint motion, power, and quick-DASH scores and VAS score were not significantly different between the two groups. CONCLUSION: Intramedullary K-wire nailing showed significant differences in posterior angulations, but both intramedullary K-wire nailing and internal fixation of plates produced good clinical outcomes in the treatment of metacarpal midshaft fracture. Therefore both techniques are considered good treatment methods.

ABSTRACT

PURPOSE: Tarsal coalition results from defects during the developmental stage and produes ankle pain and limitations in the range of motions. Its incidence has been reported to be 1%, but there has not been any reports with respect to Koreans. Therefore, we evaluated the prevalence of tarsal coalition in Koreans. MATERIALS AND METHODS: Between 2005 and 2014, we analyzed a total of 733 cases of foot and ankle magnetic resonance imaging (MRI) in our hospital. There were 391 men and 342 women. All MRI readings were read by a radiologist in our hospital. We classified the coalitions in accordance with the histological and anatomical characteristics, and calculated the prevalence in each group. Moreover, we tried to determine the prevalence of tarsal coalitions in accordance with sex, age, and proportion of the symptomatic tarsal coalitions. RESULTS: There were a total of 11 MRIs of tarsal coalition—9 talocalcaneal coalitions, 1 calcaneocuboidal coalition, and 1 calcaneonavicular coalition. Nine tarsal coalitions were observed in men and 2 in women. CONCLUSION: Through this study, we found that the prevalence of tarsal coalition, including the asymptomatic patients, is similar to the previously known prevalence (1%). By getting more MRIs of the foot and ankle, we could better represent the prevalence of tarsal coalitions in Koreans.

ABSTRACT

Marfan syndrome is an autosomal dominant and could decrease bone mineral density. So patients with Marfan syndrome could vulnerable to trauma in old ages. We present the first report, to the best of our knowledge, of a rare fracture of the femoral neck with a minor traumatic history in a juvenile Marfan syndrome patient whose physis is still open. Although the patient is young, her bone mineral density was low and the geometry of femur is changed like old ages. The femur neck fracture in children is very rare and only caused by high energy trauma, we concluded that the Marfan syndrome makes the bone weaker in young age and preventative medications to avoid fractures in younger Marfan syndrome patients are necessary in early ages.

ABSTRACT

Brown tumor refers to a change of skeletones that develops as a complication of hyperparathyroidism. As osteoclast is activated to stimulate reabsorption and fibrosis of bone, it causes a cystic change of the bone. Parathyroid carcinoma is being reported as a tumor that induces primary hyperparathyroidism. It causes excessive secretion of the parathyroid hormone and increases the blood parathyroid hormone and calcium. Bone deformation due to brown tumor is known to be naturally recovered through the treatment for hyperparathyroidism. However, there is no clearly defined treatment for lesions that can induce pathological fractures developing in lower extremities. We experienced a case where brown tumor developed in the proximal femur of a 57-year-old female patient due to parathyroid carcinoma. In this case, spontaneous fracture occurred without any trauma, and it was cured by performing intramedullary nailing fixation and parathyroidectomy. We report the treatment results along with a literature review.

ABSTRACT

Objective: This study aimed to investigate the impact on nonunion of the extent of comminution and postoperative displacement in patients surgically treated for subtrochanteric fractures


Methods: From 2008 to 2013, 44 patients with subtrochanteric fractures underwent surgery and follow-up. Retrospective data collection showed that it had 32 male and 12 female. Their mean age was 45 years. The case distribution according to Seinsheimer classification was as follows: IIA,8; IIB, 5; IIC, 7; IIIA, 8; IIIB, 3; IV, 9; and V, 4. Cephalomedullary nails were used in 28 cases; ordinary nails, in 9; and plates, in 7. After surgery, the fractures were evaluated for displacement on anteroposterior [AP] and lateral radiography


Results: Of the 44 patients, 37 achieved union from primary surgery at a mean time of 8.4 months. Five cases did not show union within the follow-up period. Two cases of nail breakage were diagnosed as non-union. Among the non-union cases, two were Seinsheimer classification IIIA; 3, IV; and 2, V. Displacement was observed on the lateral and A Pradiographs of 4 cases, on only the lateral radiographs of two cases, and in neither radiograph of one case. The risk of non-union was approximately 15.4 and 24.2 times higher when displacement was observed on the AP [95% confidence interval [CI]: 1.33-176.82] and lateral images [95% CI: 1.76-335.67], respectively


Conclusion: When displacement occurred after surgical treatment for subtrochanteric fractures, the risk of nonunion increased owing to the difficulty achieving stable fixation

ABSTRACT

OBJECTIVE: The abacus, first used in Asian countries more than 800 years ago, enables efficient arithmetic calculation via visuo-spatial configuration. We investigated whether abacus-trained children performed better on cognitive tasks and demonstrated higher levels of arithmetic abilities compared to those without such training. METHODS: We recruited 75 elementary school children (43 abacus-trained and 32 not so trained). Attention, memory, and arithmetic abilities were measured, and we compared the abacus with the control group. RESULTS: Children who had learned to use an abacus committed fewer commission errors and showed better arithmetic ability than did controls. We found no significant differences between children with and without abacus training in other areas of attention. CONCLUSION: We speculate that abacus training improves response inhibition via neuroanatomical alterations of the areas that regulate such functions. Further studies are needed to confirm the association between abacus training and better response inhibition.

ABSTRACT

BACKGROUND AND OBJECTIVES: Bone conduction (BC) auditory brainstem response (ABR) is an important factor in determining the type of hearing loss especially in infants and other difficult-to-test populations. However, multiple constraints including technical difficulties make evaluating BC ABR less feasible in the clinic, and there is also lack of information that guides clinicians how to evaluate it. The purpose of this study is to compare the latency of wave V in BC and air conduction (AC) ABR in normal hearing infants and gather reference values for wave V latency of BC ABR. SUBJECTS AND METHOD: A total of 210 ears of normal hearing, of those not belong to the hearing loss risk group, were included. All the infants underwent ABR evoked by clicks via AC (3A insert phone) and BC (Radioear B-71, vibrator positioned on the mastoid) under sedation. The latency of wave V at 30 dB nHL by BC and AC was compared and analyzed according to age. RESULTS: The results revealed that in every age group in the study, wave V latency at 30 dB nHL of BC ABR was shorter than that of AC ABR. There was a significant decrease in BC and AC latencies with age, but among each consecutive age group, significant latency change was not identified after 6 months old. CONCLUSION: The latency of BC ABR in young children was shorter than that of AC ABR, and it decreased significantly as age increased. However, the reference data should be considered by taking each laboratory's test parameter into consideration.

ABSTRACT

A 30-year-old male presented with multiple tender erythematous nodules, varying in size from 0.5 cm to 2 cm on the right shoulder of the body. He gave a history of pain associated with these lesions, especially on exposure to cold and touch. These lesions showed multi-segmental distribution; each began as a papule, which gradually increased both in size and number to form a nodule. The lesions, which were misdiagnosed as keloids at another hospital, were managed with numerous intralesional steroid injections. This treatment did not improve the symptoms. Based on the history and cutaneous findings during the physical examination, we considered a diagnosis of a benign tumor. Among the lesions, some of the larger ones were completely excised, followed by excision biopsy. We then made a diagnosis of cutaneous leiomyoma, more specifically, piloleiomyoma. The excisional lesions were covered by skin grafts and closed by primary repair.

ABSTRACT

Compartment syndrome is an ischemic change resulting from an increase in compartment pressure. Initially, patients present with direct tenderness and swelling, and the weak circulation secondary to compartment syndrome can eventually lead to motor and sensory impairment. If the increase in pressure results in neurological impairment, emergency intervention is required to decompress the compartment. Typically, compartment syndrome develops on forearms or lower legs. The gluteal compartment is rarely the location of compartment syndrome and only a few cases have been presented in the literature with trauma or hematoma. We have treated a patient with gluteal compartment syndrome who presented with no history of trauma or hemorrhage and present that case report here.

ABSTRACT

Hydroxycinnamic acids have been reported to possess numerous pharmacological activities such as antioxidant, anti-inflammatory, and anti-tumor properties. However, the biological activity of 1-p-coumaroyl beta-D-glucoside (CG), a glucose ester derivative of p-coumaric acid, has not been clearly examined. The objective of this study is to elucidate the anti-inflammatory action of CG in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. In the present study, CG significantly suppressed LPS-induced excessive production of pro-inflammatory mediators such as nitric oxide (NO) and PGE2 and the protein expression of iNOS and COX-2. CG also inhibited LPS-induced secretion of pro-inflammatory cytokines, IL-1beta and TNF-alpha. In addition, CG significantly suppressed LPS-induced degradation of IkappaB. To elucidate the underlying mechanism by which CG exerts its anti-inflammatory action, involvement of various signaling pathways were examined. CG exhibited significantly increased Akt phosphorylation in a concentration-dependent manner, although MAPKs such as Erk, JNK, and p38 appeared not to be involved. Furthermore, inhibition of Akt/PI3K signaling pathway with wortmannin significantly, albeit not completely, abolished CG-induced Akt phosphorylation and anti-inflammatory actions. Taken together, the present study demonstrates that Akt signaling pathway might play a major role in CG-mediated anti-inflammatory activity in LPS-stimulated RAW264.7 macrophage cells.
