Effect of the Computerized Emergency Consultation System on Communication Between Medical Staff for Emergency Care / 의료커뮤니케이션

Purpose@#: In emergency department(ED), emergency consultation is often omitted or delayed, resulting in an increase of the length of stay for patients. The present study investigated the emergency consultation computerized system designed for prompt and accurate communication can shorten the time for consultation care. In addition, we tried to confirm how users’ satisfaction with communication for emergency consultation changed before and after using the system. @*Methods@#: We divided the period from arrival to exit of the emergency department into 4 stages, and the time taken for each stage was measured. In addition, the present study conducted a satisfaction survey on the convenience and accuracy of communication among users. @*Results@#: After using the computerized system, the median value of time for emergency consultation treatment decreased significantly from 78 minutes to 39 minutes (p<0.001). In terms of communication convenience, more than two-thirds of the users responded positively. @*Conclusion@#: The system that computerized the initial communication shortened the time required for emergency consultation and increased satisfaction in terms of convenience of communication between medical staff.

Computer-aided design and manufacturing-based full mouth rehabilitation for a patient with excessive attrition and restricted vertical dimension: A case report / 대한치과보철학회지

This study reported the treatment of a patient with excessive worn dentition and limited maxillo-mandibular space for restoration, utilizing the computer-aided design and computer-aided manufacturing (CAD/CAM) technology. After the thorough examination of the patient's occlusal vertical dimension (OVD), full mouth rehabilitation was planned with increase of the OVD. The patient was satisfied with the provisional restorations establishing the increased OVD. The horizontal and vertical data of the patient's jaw relation that the provisional restorations contained were transferred to the definitive metal ceramic fixed prostheses by double scanning and three-dimensional printing. After the fixed restorations were cemented to the abutments, electronic surveying and three-dimensional printing were used to fabricate metal frameworks for the patient's removable partial dentures. The mandibular definitive removable prostheses were delivered to the patient's mouth and the full mouth rehabilitation procedures were completed. The digital technologies used for this case produced fixed and removable restorations satisfactory in masticatory, phonetic and aesthetic functions to both the patient and the dental clinician.

External validation of STONE score and modified STONE score

OBJECTIVE@#The STONE score and modified STONE score are useful clinical prediction rules for ureteral calculi. This study performed an external validation of the STONE score and modified STONE score. The purpose of this study was to minimize the economic cost and radiation exposure of computed tomography.@*METHODS@#The electronic medical records of patients complaining of flank pain from January 2016 to December 2017 at a single emergency department were reviewed retrospectively. The patients were classified into three groups according to the STONE score and modified STONE score. The prevalence of urethral calculi and other important alternative diagnoses were calculated in each group.@*RESULTS@#Out of 561 patients, 266 patients were enrolled in this study, and 222 patients (83.5%) had a ureteral calculus. The same 266 patients were compared using the two clinical decision rule, STONE score, and the modified STONE score. The patients were classified into three groups. The prevalence of ureteral stones in the STONE score was 18.8% in the low-score group, 81.7% in the moderate-score group, and 91.1% in the high-score group. The prevalence of the modified STONE score was 20.0% in the low-score group, 54.1% in the moderate-score group, and 93.0% in the highscore group. The area under the curve of the modified STONE score was 0.779 higher than the area under the STONE score curve 0.73.@*CONCLUSION@#The modified STONE score has superior diagnostic specificity to the STONE score.

Primary intestinal mast cell tumor in a Russian Blue cat: ultrasonographic and histopathological findings

A 11-year-old, female Russian Blue cat was presented with anorexia, vomiting, and diarrhea lasting for 3 days. Abdominal ultrasonography revealed a hypoechoic, non-circumferential, and eccentrically formed intestinal loop with altered wall layering and thickening of the tunica muscularis. After surgical resection, histopathologic examination confirmed an infiltrative, round-cell neoplasm composed of sheets and cords of neoplastic mast cells within a fibrotic, edematous stroma. The cat was alive and healthy 6 months after surgery. To the best of our knowledge, this is the first reported case of an intestinal mast cell tumor in a Russian Blue cat in South Korea.

A Case of Ascites without Liver Failure in Patient with Valproic Acid Intoxication

Valproic acid (VA) has been used for treatment of various convulsive disorders. As its use has increased, many complications of VA have been reported. Complications include significantly dangerous organ failures such as liver failure, brain edema, respiratory arrest, and pancreatitis, and so on. Some clinicians have reported rare cases of ascites with liver failure and necrotizing pancreatitis in patients with VA overdose. However, no case of ascites without organ problems has been reported. A 19 year-old man who was intoxicated with VA was transferred to our hospital. He had abdominal distension with a moderate amount of ascites despite having no organ dysfunction. We will describe this rare case.

The Relationship between Rainfall and Traffic Accident Patients in Busan

PURPOSE: Traffic accidents are increasing due to the development and increment of transportation. Previous studies on analysis of the correlation between environmental factors and traffic accidents have rarely been reported. The purpose of this study is to analyze the correlation between rainfall and traffic accidents including accident mechanism, incidence, and trauma severity of patients. METHODS: A retrospective review was conducted in 851 trauma patients who visited the emergency department (ED) after a traffic accident from January 2013 to December 2013; 248 patients due to a traffic accident when it was raining, and 603 patients when it was not raining. Demographic data, clinical data, and meteorological data (rainfall, daily mean air temperature, daily mean wind speed) in Busan were investigated. RESULTS: The incidence of traffic accidents was one-second and the injury severity score of patients was two points higher on rainy days. In addition, the length of hospital stay was three days longer (p=0.037), and the prognosis was poor in the rain group. Comparison of severe injury sustained over rain, injury time, and accident mechanism showed approximately a 3-fold odds increased rate of severe injury on rainy days (OR 2.55, 95% CI: 1.11-5.83, p=0.004) and a seven-fold odds increased rate of pedestrian traffic accidents (OR 7.26, 95% CI: 3.52-9.26, p<0.001) compared with car traffic accidents. In addition, a four-fold increased odds of night time (OR 3.79, 95% CI: 1.98-7.25, p<0.001) compared with day time accidents on rainy days. CONCLUSION: The incidence of traffic accidents and injury severity of patients increased on rainy days. Therefore, we suggest expansion of the scope of the emergency and trauma team activation for proper treatment on rainy days.

Comparative Analysis of Laparoscopic Versus Open Appendectomy for Perforated Appendicitis in Children Under 12 Years Old at a Single Institute

PURPOSE: The purpose of this study is to evaluate the outcome of laparoscopic (LA) vs. open appendectomy (OA) in children under 12 years old with perforated appendicitis. METHODS: We reviewed the medical files of 156 children who underwent LA (n=96), OA (n=59), and conversion (CO) (n=1), and compared duration of operation, length of hospital stay, incidence of wound infection, mechanical ileus, intra-abdominal abscess (IAA), and re-admission. RESULTS: Compared to OA, LA resulted in longer duration of operation (58.32+/-17.105 min vs. 44.27+/-18.735 min; p=0.001), but fewer wound infections (2.1% vs. 10.2%; p=0.054), and fewer cases of mechanical ileus (0% vs. 5.1%; p=0.053). No differences in the length of hospital stay (5.85+/-1.824 days vs. 6.10+/-3.027 days; p=0.526), IAA (2.1% vs. 1.7%; p=1.000), or re-admissions (2.1% vs. 5.1%; p=0.369) were observed. CONCLUSION: We report that although LA showed an association with longer duration of operation compared to OA, it is superior to OA with regard to incidence of wound infection and mechanical ileus.

Gastric Lymphoepithelioma-like Carcinoma Diagnosed and Treated by Endoscopic Submucosal Dissection: Review of the Literature / 대한소화기내시경학회지

Gastric lymphoepithelioma-like carcinoma (LELC) is a rare neoplasm of the stomach that features undifferentiated carcinoma mixed with lymphoid stroma, and it invariably has a good prognosis. Most gastric LELCs have been linked to Epstein-Barr virus (EBV) infection. We experienced a case of a patient with gastric LELC. A 57 years old female patient was found to have shallow irregular ulcerative lesion on the gastric antrum. Although repetitive endoscopic biopsy didn't yield any cancer, early gastric cancer (EGC) was strongly suspected. Endoscopic submucosal dissection (ESD) was performed for establishing the correct diagnosis and curatively resecting the lesion. The pathology revealed gastric LELC with vertical invasion to the submucosa. No remnant cancer and no lymph node metastasis were noted after surgery following ESD. Here, we are reporting on a case of gastric ELEC along with reviewing the relevant literature. We believe this is the first case of gastric ELEC that was successfully diagnosed and managed by ESD.

A Case of Non-occlusive Ischemic Colitis of the Right Colon after Percutaneous Coronary Intervention / 대한소화기내시경학회지

Ischemic colitis is the most common form of gastrointestinal ischemic injury. Indeed, many medical conditions and medications can cause reduced blood flow to the colon. The splenic flexure, descending colon, and sigmoid colon are most commonly affected. Involvement of only the right colon is an infrequent occurrence. Ischemic colitis of the right colon usually is associated with low flow states. Given the high morbidity and mortality of this disorder, early diagnosis and aggressive management is critical. Ischemic colitis associated with heart disease, such as congestive heart failure, myocardial infarction, arrhythmias, aortic valve disease, and atherosclerotic cardiovascular disease, is usually due to low cardiac output, or to disease states resulting in dehydration, or to the splanchnic vasoconstrictive effect of some medications. Here we present a case of nonocclusive ischemic colitis of the right colon after percutaneous coronary intervention for unstable angina. The colitis was successfully treated with conservative management.

A Case of Large Retroperitoneal Lipoma Mimicking Liposarcoma / 대한소화기학회지

Lipomas are the most common benign tumors of adipose tissue among adults. Lipomas can occur almost anywhere in the trunk, extremities, mediastinum, and pelvis, but retroperitoneal lipomas are extremely rare. It should be distinguished from well differentiated liposarcoma in order to provide the appropriate treatment and follow up. We experienced a case of 60-year-old patient with large retroperitoneal lipoma mimicking liposarcoma causing palpable abdominal mass and pain. Abdominal computerized tomography (CT) showed 33x22 cm sized bulky fat-containing mass with contrast enhanced solid portion in right retroperitoneum. Positron emission tomograpgy (PET) revealed increased 18F-FDG uptake at solid portion shown in abdominal CT. Imaging studies confirmed a high index of suspicion on liposarcoma. Laparotomy showed a large encapsulating tumor arising from retroperitoneum with fat necrosis. Pathologic examination of resected specimen revealed normal mature adipocytes without atypical cells, compatible with lipoma.

Periampullary Gangliocytic Paraganglioma Successfully Treated by Endoscopic Mucosal Resection / 대한소화기내시경학회지

Gangliocytic paraganglioma is a rare tumor that occurs nearly exclusively in the second portion of the duodenum. This tumor is usually considered to be benign. So, endoscopic resection may be the best procedure to facilitate the diagnosis and for treatment to avoid an unnecessary, invasive operation. To the best of our knowledge, this is the first report of a periampullary gangliocytic paraganglioma that was successfully treated by endoscopic mucosal resection in Korea. We report here a case of a 45-year-old man who was found to have a periampullary gangliocytic paraganglioma. This tumor was adequately treated by endoscopic mucosal resection.

Second-tier Instruction of Cardiopulmonary Resuscitation by CPR Anytime(R) Trainees

PURPOSE: CPR Anytime(R), a self-instructional video program, has gained popularity amongst CPR instructors for training non-healthcare providers. This instructional kit enables second-tier instruction. The purpose of this study is to determine the status of second-tier instruction CPR by CPR Anytime(R) trainees. METHODS: Questionnaires were sent to 606 CPR Anytime(R) trainees from 12 BLS training sites. The training period was from October 2006 to July 2007. Questionnaires included provider's basic information, post-course self exercise, amount of second-tier instruction, and multiplier status. RESULTS: The response rate of the questionnaire was 53.6%(325). The mean age was 20.4+/-10.3 years old. The professions of respondents were as follows: students (76.3%), office workers(13.2%), teachers(4.4%), and service providers(1.9%). The post-course self exercise rate was 49% with three fourths of those completing the exercises using both the DVD and MiniAnne(R). Second-tier instruction tools use rates(48%) were as follows: DVD and manikin(35%), manikin only(9%), verbal only(2%), and DVD only(1%). The total multiplier effect was 1.77(575/ 325) with the multiplier effect of teachers significantly higher than others. CONCLUSION: This study found that 48% of CPR Anytime(R) providers perform second-tier instruction to family and friends. Amongst them, the total multiplier effect was 1.77 (575/325).

A Case of an Eosinophilic Granuloma Mimicking a Submucosal Tumor in the Ascending Colon Probably Caused by Anisakis / 대한소화기내시경학회지

Anisakiasis in the gastrointestinal tract is caused by the ingestion of raw marine fish that contain Anisakis lavae. In rare cases, Anisakiasis is found as an eosinophilic granuloma that mimics a submucosal tumor. The diagnosis is usually made after surgical resection. Several cases of gastric anisakiasis imitating a submucosal lesion have been reported. However, colonic anisakiasis forming a submucosal lesion is very rare and only a few cases have been reported. All of the cases were confirmed after surgery. Recently, we encountered a male patient with a submucosal lesion on the ascending colon during a health screening. Several biopsies were performed on the same site as the lesion. The pathological finding was eosinophilic granuloma. We tentatively diagnosed the patient with eosinophilic granuloma due to Anisakis as the patient consumed raw seafood and eosinophilia was detected on a laboratory test. We decided not to perform any procedure. One month later, the eosinophilic granuloma disappeared as seen on a follow-up colonoscopy.

A Case of Jejunogastric Intussusception that was Diagnosed by Gastroscopy in a Patient who had Undergone Subtotal Gastrectomy / 대한소화기내시경학회지

Jejunogastric intussusception is a rare, but potentially lethal complication after gastrectomy or gastrojejunostomy. In the acute condition, early diagnosis and prompt surgical treatment are mandatory to reduce the incidence of mortality. We present here a case of jejunogastric intussusception that was diagnosed by gastroscopy in a patient with a history of subtotal gastrectomy, and she had experienced increasing epigastric pain and vomiting for 1 day.

Cause, effect and coping skills of stress in physicians and nurses of an emergency department

PURPOSE: The emergency department (ED) has been considered highly stressful environment to work in. However, there has been no study evaluating the stresses endured by emergency staffs in Korea. This study aims to evaluate the cause and effect of stress, and coping methods used by doctors and nurses under stress from working in an emergency department. METHODS: Interns, residents and nurses of an emergency center were given questionnaires that included general health questionnaire (GHQ)-12 scale and modified Holmes & Rahe (HR) scale to examine the cause and effect of stress, and determine the coping methods they used to alleviate stress. A score of greater than 20 in the GHQ-12 scale and greater than 80 in the HR scale were considered as significant for stress. The stress scales were compared among the three groups using analysis of variance and chisquare test. RESULTS: A total of 111 participants consisting of 46 interns, 19 residents, and 46 nurses were surveyed. While the GHQ-12 score showed no difference between groups, the HR score showed significant differences among residents (82.4+/-23.0), nurses (73.6+/-13.2), and interns (70.1+/-17.7). Each stress score did not differ according to the age, gender, marital status, or presence of lover. Most frequently recorede effects of stress were difficulty waking up and fatigue. Most frequent coping methods employed were sleeping and smoking. CONCLUSION: This study suggests that ED staffs, especially residents, were exposed to significant amount of stress.

A Case of Unilateral Submandibular Glandular Aplasia / 대한이비인후과학회지

The congenital absence of the major salivary glands is an uncommon disorder, although it is not always symptomatic. Their etiopathogenesis is poorly understood. Aplasia of the salivary glands may occur either in isolation or in association with other developmental abnormalities. Some authors have reported familial salivary gland aplasia. Aplasia may be partial or total. Severely affected patients suffer from dry mouth and an increased rate of dental decay. Following clinical exclusion of the cause of these symptoms, the diagnosis of submandibular gland aplasia can be confirmed by computed tomography and a Tc-99m pertechnate scintiscan. The authors experienced a case of incidentally detected, unilateral submandibular glandular aplasia in a 38-year old female. So we present this case with review of literatures.

A Case of Frontal Ganglioglioma Coincidence with Pituitary Adenoma

A case of frontal ganglioglioma coexisting with pituitary adenoma is reported. A 37-year-old male presented with chief complaint of headache for 2 months. A neurological examination of the patient revealed no deficit. Brain MRI showed a well enhanced lobulated mass on left frontal lobe and another homogeneously enhanced mass on intrasellar and suprasellar portion. The frontal mass was grayish in color and rubbery hard in consistency on operative field, having relatively good boundary from the adjacent normal brain tissue. The sellar mass was 3X3cm in size and compressed optic chiasm. Histological diagnosis of frontal mass was ganglioglioma and sella mass showed typical features of pituitary adenoma.
