ABSTRACT
When restoring with a dental digital system for implant-supported prosthesis, a double digital scanning technique is required: an intraoral scan of the three-dimensional implant location and intraoral scan after placement of temporary denture or provisional prosthesis. During the intraoral scan, the use of scan body as a stable landmark can improve the accuracy of digital impression and simplify laboratory process. In this case, a full-digital system was used to plan and fabricate a custom abutment, provisional prosthesis, and definitive prosthesis. After implant placement, the scan area of the intraoral scan body connected with implant and the intraoral scan body marked on the inside of temporary denture were superimposed. Out of the superimposed files, a custom abutment and provisional prosthesis were fabricated which match the vertical dimension of temporary denture, and definitive prosthesis was fabricated based on provisional prosthesis. We report this case because result has been functionally and esthetically satisfactory by using vertical dimension and central relation set during the fabrication of temporary denture to the definitive prosthesis.
ABSTRACT
Background@#Atopic dermatitis (AD) is a chronic inflammatory skin disease that often results in a severely reduced quality of life due to its irritating symptoms. Cooling the skin can be an effective supplement for pruritus in the case of AD, since it can modulate itch sensitivity, which has an antipruritic effect. @*Objective@#The aim of this study was to evaluate the effect of a soothing cooler on relieving pruritus in the case of mild AD. @*Methods@#Thirty patients with mild AD were enrolled in this study. They were advised to use the soothing cooler on their left forearms twice daily for eight weeks. Immediate responses were assessed at baseline, and follow-up was done at weeks 2, 4, and 8 to evaluate long-term responses. The effect of the soothing cooler was evaluated using the visual analogue scale for pruritus, transepidermal water loss, hydration capacitance, and the Investigator’s Global Assessment scale for AD. Safety was monitored through the report of adverse events during the study period. @*Results@#There were immediate and long-term improvements in the visual analogue scale scores of left forearm pruritus (p＜0.05), which were statistically significant. No adverse event was reported during the study period. @*Conclusion@#The results of this study demonstrated the pruritus-relieving effect of the soothing cooler for patients with mild AD.
ABSTRACT
Purpose@#Management options for extraperitoneal bladder injury (EBI) associated with pelvic fracture are variable. Predictive factors of operative management (OM) in patients with EBI associated pelvic fracture have not been previously addressed. This study assessed the current epidemiology of blunt traumatic urinary bladder injury and evaluated relevant clinical findings of patients with EBI associated with pelvic fracture who received OM. @*Methods@#Patients with urinary bladder injury with or without pelvic fracture from blunt trauma from January 1, 2014 to December 31, 2019 were identified from the institute trauma registry (n = 12,891). Demographics, mechanism of injury, type of urinary bladder injury, pelvic fracture configuration, and management options were analysed in the study population (n = 9,894). @*Results@#Of the 1,400 patients who had pelvic and/or acetabular fracture, 32 (2.3%) had urinary bladder injury. Of the 8,494 patients without pelvic and/or acetabular fracture, 12 (0.1%) had nonpelvic fracture urinary bladder injury. The total incidence of urinary bladder injuries in the study population was 0.4% (44/9,894). Patients with EBI associated with pelvic fracture who underwent OM, had a higher frequency of high-grade pelvic injury (100% vs 0%, p = 0.015), concomitant pelvic surgery (75.0% vs 0%, p = 0.001), and non-lateral compression type pelvic fracture (62.5% vs 10.0%, p = 0.043) compared with patients who underwent non-operative management of EBI. @*Conclusions@#These data suggest that OM may be considered especially in patients with EBI associated with pelvic fracture with high grade pelvic injury, concomitant pelvic surgery, and nonlateral compression type pelvic fracture.

ABSTRACT
Purpose@#Managing patients with hemorrhagic shock is mainly dependent on stopping the bleeding as fast as possible. Emergency Department laparotomy (EDL) is considered one of the approaches to control intra-abdominal bleeding rapidly. This study aims to evaluate the outcomes of EDL in a regional trauma center of Pusan National University Hospital in a 4-year period. @*Methods@#The medical records and data of patients who underwent EDL from January 2016 to December 2019 were analyzed. Patients who underwent preperitoneal pelvic packing only or did not receive surgery immediately after EDL were excluded. @*Results@#Twenty-four patients who underwent EDL were included in the study. 18 patients had sustained blunt trauma, and 6 suffered from penetrating injuries. Small bowel mesentery and liver injuries were the most frequent. Increase of median systolic blood pressure (SBP) after EDL was 55.5 mmHg. Four (16.7%) out of the 24 survived; one of the four survivors received cardiopulmonary resuscitation (CPR). In the nonsurvivor group, Injury Severity Score was significantly higher (p = 0.013), initial pH was lower (p = 0.035) and the amount of packed red blood cells transfusion after EDL was significantly higher (p = 0.013) than those in the survivor group. @*Conclusion@#The mortality rate was very high in trauma patients who were required EDL. Although EDL was not proved to be an effective procedure for resuscitation in trauma patients, it could be considered as one of the treatment options for trauma patients in extremis. Further studies are required to examine the effects of EDL.

ABSTRACT
Acquired hemophilia A (AHA) is a rare disease where typically coagulation factor VIII is inhibited by autoantibodies. It occurs in patients with no personal or familial history of bleeding. In this case study a 61-year-old male presented with a huge psoas hematoma. He had no history of bleeding disorders. He was initially diagnosed with delayed traumatic hematoma. Despite conservative and surgical treatments, coagulopathy was not resolved and postoperative bleeding continued. Consequently, coagulation factor tests were performed and showed reduced activity of factor VIII (2.7%). In addition, factor VIII inhibitor was detected. The patient was diagnosed with AHA and administered recombinant factor VIII for 3 days which resulted in the cessation of bleeding. AHA can lead to a life-threatening hemorrhage, and needs to be considered in differential diagnoses in any patients presenting with unexplained and repeated bleeding, where there is no personal or familial history of bleeding disorders.

An isolated pancreatic transection due to blunt trauma is a rare occurrence that usually requires surgical treatment. Non-surgical treatment for a pancreatic transection remains controversial because of its associated complications. On the other hand, non-surgical treatment has been used increasingly as a treatment option with promising results in recent years. A patient presented with a suspected pancreatic injury caused by a motorcycle accident. The computed tomography findings revealed an isolated pancreatic neck transection with a small amount of fluid collection. He was hemodynamically stable without signs of peritoneal irritation. Endoscopic retrograde pancreatography and stent insertion were performed. The patient had no significant complications and was discharged on day 18. The stent was removed on day 103 and the patient showed good recovery. For an isolated pancreatic transection, endoscopic intervention can be considered as an alternative with a good outcome in selected patients.

The concept of acute care surgery (ACS) incorporates trauma, surgical critical care, and emergency general surgery. It was designed in the early 2000s by the United States as a solution to the looming crisis of trauma care and non-trauma emergency surgery. Reduced surgical opportunities for trauma surgeons resulted in a decreased interest in trauma surgery. Surgical sub-specialization further accelerated an indifference towards trauma and emergency general surgery. Started in 2008, the trauma center project in Korea is still in its infancy. Although the need for ACS was presented since the inception of the trauma center project, there was a lack of implementation at trauma centers due to government regulations. However, ACS has been initiated at several non-trauma center hospitals and is mainly operated by surgical intensivists. Studies demonstrate that adding emergency surgery to a trauma service does not compromise the care of the injured patients, despite an increase in trauma volume. Positive impacts of ACS are reported by numerous researches. We believe that the development and advancement of trauma centers will necessitate a discussion for the implementation of the ACS model at trauma centers in Korea.

OBJECTIVE: When managing patients with acute meningitis in an emergency department (ED), early diagnosis of the type of infection (bacterial or viral) considerably affects the clinical course and treatment because of the high mortality and morbidity associated with bacterial meningitis (BM). The serum delta neutrophil index (DNI), a new inflammatory marker, reflects the fraction of circulating immature granulocytes and is elevated in cases of bacterial infection. The objective of this study was to evaluate whether serum DNI can be used to differentiate between BM and viral meningitis (VM) in the ED. METHODS: This retrospective, observational study included 104 consecutive patients (aged >18 years) diagnosed with acute meningitis from January 2012 to November 2014 in a regional emergency center. White blood cell and neutrophil counts, C-reactive protein level, and DNI were evaluated regarding their usefulness for differentiating BM and VM. RESULTS: Serum DNI was not significantly higher in the BM group (n=12) than in the VM group (n=92) (0 [interquartile range, 0% to 2.73%] vs. 0 [interquartile range, 0 to 0%], P=0.057). However, the white blood cell count and C-reactive protein level were statistically higher in the BM group (P=0.034 and P=0.026, respectively). Serum DNI was not found to be a statistically useful differential diagnostic parameter (area under the curve, 0.628; 95% confidence interval, 0.438 to 0.818). CONCLUSION: Currently, there is no evidence that the serum DNI aids in differentiating acute BM from acute VM in the ED.

Developing of digital technique, it is possible to fabricate implant prostheses for edentulous area using intraoral 3-dimentional information throughout implant diagnosis and treatment process. It is being changed that from the method using CAD/CAM, producing prostheses by model scanning after conventional impression and model processing, to the method of fabricating implant provisional restorations and customized abutments by digital impression after connecting digital impression copings (scanbody) and implant fixtures without models. But, this digital method has not been actively used for implant prostheses not yet. Specially, it is short of intraoral digital impression cases for immediate provisional restorations of the maxillary anterior implants. The gingival contour impression of maxillary anterior area is very important for esthetic restorations. Accordingly, in this case report, the using a digital impression coping (scanbody) and digital impression by CEREC Omnicam (Sirona, Bensheim, Germany) or Trios (3shape, Copenhagen, Denmark) were introduced for immediate provisional restorations in 3 cases needed a single implant restoration in maxillary anterior area. The clinical results were satisfactory on the convenience and accuracy of digital impression technique and the good esthetics of final restorations.

Papillary thyroid cancer (PTC) has a good prognosis and a low incidence of distant metastases. It is extremely rare for PTC to metastasize to the pancreas. Only five cases have been previously reported worldwide. Most cases are discovered incidentally by abdominal computed tomography (CT) or positron emission tomography-CT (PET-CT) during follow-up studies after thyroidectomies. Pancreatic metastasis of PTC is usually unidentifiable by a whole-body I131 scan, a common follow-up modality. When a pancreatic mass is found in patients with PTC, it must be differentiated from pancreatic cancer. In previous reports, patients with pancreatic metastases of PTC underwent operations for therapeutic diagnosis or underwent fine needle aspiration biopsies (FNAB). However, it is unclear whether the benefit of an operation outweighs the risk. We experienced a case of PTC with pancreatic metastasis that was found on PET-CT. Contrast-enhanced endoscopic ultrasonography (EUS) was performed to evaluate the characteristics of the pancreatic mass and pathological confirmation was obtained cytologically via EUS-FNA.

ABSTRACT
BACKGROUND AND PURPOSE: Charcot-Marie-Tooth disease (CMT) type 1A (CMT1A) is the demyelinating form of CMT that is significantly associated with PMP22 duplication. Some studies have found that the disease-related disabilities of these patients are correlated with their compound muscle action potentials (CMAPs), while others have suggested that they are related to the nerve conduction velocities. In the present study, we investigated the correlations between the disease-related disabilities and the electrophysiological values in a large cohort of Korean CMT1A patients. METHODS: We analyzed 167 CMT1A patients of Korean origin with PMP22 duplication using clinical and electrophysiological assessments, including the CMT neuropathy score and the functional disability scale. RESULTS: Clinical motor disabilities were significantly correlated with the CMAPs but not the motor nerve conduction velocities (MNCVs). Moreover, the observed sensory impairments matched the corresponding reductions in the sensory nerve action potentials (SNAPs) but not with slowing of the sensory nerve conduction velocities (SNCVs). In addition, CMAPs were strongly correlated with the disease duration but not with the age at onset. The terminal latency index did not differ between CMT1A patients and healthy controls. CONCLUSIONS: In CMT1A patients, disease-related disabilities such as muscle wasting and sensory impairment were strongly correlated with CMAPs and SNAPs but not with the MNCVs or SNCVs. Therefore, we suggest that the clinical disabilities of CMT patients are determined by the extent of axonal dysfunction.

A 18-year-old girl visited the hospital due to hematochezia. Colonoscopy revealed a 6-mm Yamada type II polyp with stigmata of bleeding, and a shallow ulcer on top was found at the cecum base. The polyp was removed by snare polypectomy, and hematochezia stopped thereafter. Angiodysplasia was diagnosed histopathologically. Generally, angiodysplasia appears as a flat or elevated, bright-red lesion on endoscopy, with a polypoid shape being extremely rare. This case is significant because the lesion occurred at the youngest reported age and was the smallest that has been reported, and is the only polypoid arteriovenous malformation to be discovered in the cecum.

Heterotopic gastric mucosa in the upper esophagus, in which the inlet patch is a salmon-colored valvet patch, is located mainly below the upper esophageal sphincter. The acid secretion and inflammation from heterotopic gastric mucosa causes laryngopharyngeal symptoms. Generally, the management of heterotopic gastric mucosa depends on the symptoms, and the condition is generally treated by proton pump inhibitor. Recently, it was reported that argon plasma coagulation (APC) is effective when medical treatment fails. A 49-year-old man and a 44-year-old woman with symptoms of globus sensation and hoarseness visited this clinic. An upper gastrointestinal endoscopy showed a flat salmon-colored patch located at the upper esophagus. The former patient failed medical treatment and the latter did not require long term medical treatment. Therefore, the patients were treated with APC, which resulted in an improvement in symptoms. APC treatment may improve the symptoms of patients with heterotopic gastric mucosa of the cervical esophagus.

In retrieving bile duct stones, full-endoscopic sphincterotomy (EST) with endoscopic mechanical lithotripsy (EML) is considered as a traditional method, and balloon dilation of the papillary sphincter has also been used. Recent studies have reported that mid-EST and endoscopic papillary large balloon dilatation (EPLBD) was as useful as full-EST with EML, without serious complications. In patients with coagulopathy, such as end-stage renal disease, even a small incision of the sphincter could cause profuse bleeding. In such patients, balloon dilation of the sphincter is a preferred technique over EST. A prior Billroth-II operation renders EST more difficult and increases the risk of a complication. In these patients, the use of EPBD is also preferred as well. We report a case of successfully retrieving large bile duct stones by EPLBD without EST, in a patient who had a prior Billroth-II operation, and is undergoing hemodialysis. The patient is free of complications, such as bleeding or acute pancreatitis.

Hyperhomocysteinemia is an independent risk factor for cerebrovascular disease. Hyperhomocysteinemia can be caused by the defect of the remethylation pathway including the 5, 10-methylenetetrahydrofolate reductase (MTHFR) gene or the transsulfuration pathway including the cystathionine beta-synthase (CBS) gene of homocysteine metabolism. The major cause of severe hyperhomocysteinemia is CBS gene mutation. A 16-year-old male was admitted with vertigo. Brain MRI showed right cerebellar infarction. The plasma homocysteine level was 175 mocro mol/L. According to a genetic evaluation, the patient had the MTHFR 677TT and CBS 1080TT genotypes.
