Efficacy of serious games for chronic pain management in older adults: A systematic review and meta-analysis.

AIMS AND OBJECTIVES: To synthesise and appraise the evidence of the efficacy of serious games in reducing chronic pain among older adults. BACKGROUND: Chronic pain in older adults generally results in a substantial handicap due to decreased mobility, exercise avoidance and various concerns that affect their overall quality of life. While serious games have been widely used as a pain management approach, no reviews have thoroughly examined their efficacy for chronic pain management in older adult populations. DESIGN: A systematic review and meta-analysis. METHODS: The CINAHL, the Cochrane Library, Embase, Medline, PubMed and Web of Science databases were comprehensively searched to find articles published from their inception until 17 April 2023. RoB-2 was used to assess the risk of bias in the included studies. The efficacy of serious games for pain management in older individuals was investigated using pooled standardised mean differences (SMDs) in pain reduction using a random effect model. RESULTS: The meta-analysis comprised nine randomised controlled trials that included 350 older adult patients with pain. Serious games effectively alleviated pain in this group (pooled SMD = -0.62; 95% confidence interval: -1.15 to -0.10), although pain-related disability and fear require further investigation. CONCLUSIONS: Serious games tended to effectively reduce pain in this older adult group; however, due to a lack of randomised controlled trials, the analysis found lower effectiveness in reducing pain-related disability and fear. Further studies are accordingly required to confirm these findings. RELEVANCE TO CLINICAL PRACTICE: The findings of the study emphasise the importance of serious games to increase the motivation of older adults to exercise as one of the safe and extensively used pain management strategies. Serious games that effectively reduce chronic pain in older adults are characterised as consisting of diverse physical activities delivered through consoles, computer-based activities and other technologies. PATIENT OR PUBLIC CONTRIBUTIONS: Serious games are recommended as being potentially useful and practical for reducing pain in older adults.

K-Rod: An Innovative Method of Personalized Rib Splinting for Expeditious Management of Flail Chest in Acute Care Settings.

Flail chest is a severe type of multiple rib fracture that can cause ventilation problems and respiratory complications. Historically, flail chest has been mainly managed through pain control and ventilatory support as needed. Operative fixation has recently become popular for the condition, and some studies have revealed its potentially positive effects on the outcomes of patients with flail chest. However, for those for whom surgery is unsuitable, few treatment options, other than simply providing analgesia, are available. Herein, we introduce our innovative method of applying personalized rib splinting for quick management of flail chest, which is easy, tailor-made, and has significant effects on pain reduction.

Low-Voltage Electricity-Associated Burn Damage of Lung Parenchyma: Case Report and Literature Review.

BACKGROUND: Electrical injuries are common in daily life. The severity of electrical injury depends on the electric current, and assessing electrical damage is difficult because there appears to be no correlation between skin burns and visceral injury. We report a case of bilateral lung injury with pulmonary hemorrhage after exposure to low-voltage electricity. CASE REPORT: A 23-year-old man was shocked by a low-voltage (110 V) electric current while at work. He had temporary loss of consciousness and twitching in the extremities, but soon regained consciousness and spontaneously stopped twitching. Electrical burn wounds were discovered on his back and forehead. Dyspnea and hemoptysis were noted. A computed tomography scan of the chest revealed patchy infiltration and consolidation of both lungs. The patient received treatment of tranexamic acid and prophylactic antibiotics for electricity-induced lung injury and pulmonary hemorrhage. Resolution of chest radiograph abnormalities was recorded on day 7. The mild dyspnea ceased approximately 2 weeks later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Electricity-induced lung injury should be considered in patients with electrical injury through a suspicious electrical current transmission pathway, respiratory symptoms, and corresponding imaging findings. Pulmonary complications can be serious and require early intervention.

How to effectively obtain informed consent in trauma patients: a systematic review.

BACKGROUND: Obtaining adequate informed consent from trauma patients is challenging and time-consuming. Healthcare providers must communicate complicated medical information to enable patients to make informed decisions. This study aimed to explore the challenges of obtaining valid consent and methods of improving the quality of the informed consent process for surgical procedures in trauma patients. METHODS: We conducted a systematic review of relevant English-language full-text original articles retrieved from PubMed (1961-August 2018) that had experimental or observational study design and involved adult trauma patients. Studies involving informed consent in clinical or research trials were excluded. Titles and abstracts of searched articles were reviewed and relevant data were extracted with a structured form. Results were synthesized with a narrative approach. RESULTS: A total of 2044 articles were identified in the initial search. Only eight studies were included in the review for narrative synthesis. Six studies involved orthopedic surgeries, one involved nasal bone surgeries, and one involved trauma-related limb debridement. Only one study was conducted in an emergency department. Information recall was poor for trauma patients. Risk recall and comprehension were greater when written or video information was provided than when information was provided only verbally. Patient satisfaction was also greater when both written and verbal information were provided than when verbal information alone was provided; patients who received video information were more satisfied than patients who received written or verbal information. CONCLUSIONS: Many articles have been published on the subject of informed consent, but very few of these have focused on trauma patients. More empirical evidence is needed to support the success of informed consent for trauma patients in the emergency department, especially within the necessarily very limited time frame. To improve the informed consent process for trauma patients, developing a structured and standardized informed consent process may be necessary and achievable; its effectiveness would require evaluation. Adequately educating and training healthcare providers to deliver structured, comprehensive information to trauma patients is crucial. Institutions should give top priority to ensuring patient-centered health care and improved quality of care for trauma patients.

Educational video-assisted versus conventional informed consent for trauma-related debridement surgery: a parallel group randomized controlled trial.

BACKGROUND: We investigated whether, in the emergency department (ED), educational video-assisted informed consent is superior to the conventional consent process, to inform trauma patients undergoing surgery about the procedure, benefits, risks, alternatives, and postoperative care. METHODS: We conducted a prospective randomized controlled trial, with superiority study design. All trauma patients scheduled to receive trauma-related debridement surgery in the ED of Kaohsiung Medical University Hospital were included. Patients were assigned to one of two education protocols. Participants in the intervention group watched an educational video illustrating informed consent information, whereas those in the control group read an informed consent document. The primary outcome was knowledge scores and the secondary outcome was assessment of patient satisfaction. A multivariable regression model, with predefined covariates, was used to analyze differences in knowledge scores and patient satisfaction levels between the groups. RESULTS: A total of 142 patients were enrolled, with 70 and 72 assigned to the intervention and control groups, respectively. Mean knowledge scores were higher in the intervention (72.57 ± 16.21 (SD)) than in the control (61.67 ± 18.39) group. By multivariate analysis, the intervention group had significantly greater differences in knowledge scores (coefficient: 7.646, 95% CI: 3.381-11.911). Age, injury severity score, and baseline knowledge score significantly affected the differences in knowledge scores. Significant improvements were observed in patients' perception of statements addressing comprehension of the information provided, helpfulness of the supplied information for decision making, and satisfaction with the informed consent process. Multivariate analysis showed significant correlations between video education and patient satisfaction. CONCLUSIONS: Both the educational approach and severity of injury may have an impact on patient understanding during the informed consent process in an emergency environment. Video-assisted informed consent may improve the understanding of surgery and satisfaction with the informed consent process for trauma patients in the ED. Institutions should develop structured methods and other strategies to better inform trauma patients, facilitate treatment decisions, and improve patient satisfaction. TRIAL REGISTRATION: The ClinicalTrials.gov Identifier is NCT01338480 . The date of registration was April 18, 2011 (retrospectively registered).

Development and pilot testing of an informed consent video for patients with limb trauma prior to debridement surgery using a modified Delphi technique.

BACKGROUND: Ensuring adequate informed consent for surgery in a trauma setting is challenging. We developed and pilot tested an educational video containing information regarding the informed consent process for surgery in trauma patients and a knowledge measure instrument and evaluated whether the audiovisual presentation improved the patients' knowledge regarding their procedure and aftercare and their satisfaction with the informed consent process. METHODS: A modified Delphi technique in which a panel of experts participated in successive rounds of shared scoring of items to forecast outcomes was applied to reach a consensus among the experts. The resulting consensus was used to develop the video content and questions for measuring the understanding of the informed consent for debridement surgery in limb trauma patients. The expert panel included experienced patients. The participants in this pilot study were enrolled as a convenience sample of adult trauma patients scheduled to receive surgery. RESULTS: The modified Delphi technique comprised three rounds over a 4-month period. The items given higher scores by the experts in several categories were chosen for the subsequent rounds until consensus was reached. The experts reached a consensus on each item after the three-round process. The final knowledge measure comprising 10 questions was developed and validated. Thirty eligible trauma patients presenting to the Emergency Department (ED) were approached and completed the questionnaires in this pilot study. The participants exhibited significantly higher mean knowledge and satisfaction scores after watching the educational video than before watching the video. CONCLUSIONS: Our process is promising for developing procedure-specific informed consent and audiovisual aids in medical and surgical specialties. The educational video was developed using a scientific method that integrated the opinions of different stakeholders, particularly patients. This video is a useful tool for improving the knowledge and satisfaction of trauma patients in the ED. The modified Delphi technique is an effective method for collecting experts' opinions and reaching a consensus on the content of educational materials for informed consent. Institutions should prioritize patient-centered health care and develop a structured informed consent process to improve the quality of care. TRIAL REGISTRATION: The ClinicalTrials.gov Identifier is NCT01338480 . The date of registration was April 18, 2011 (retrospectively registered).

Global prevalence of anxiety and depression among medical students during the COVID-19 pandemic: a systematic review and meta-analysis.

PURPOSE: As future physicians, medical students have experienced tremendous pressure during the ongoing COVID-19 pandemic, which is associated with a high risk of depression and anxiety. We aimed to investigate an overview of the prevalence of anxiety and depression among medical students in various countries during the global COVID-19 pandemic, and discuss associated stressors. METHODS: We systematically searched CINAHL, EMBASE, MEDLINE, PubMed, and Web of Science for relevant articles from December 1, 2019 to March 15, 2023. We performed meta-analysis using a random-effects model with REML method to calculate the pooled prevalence of anxiety and depression. Begg's and Egger's tests were used to identify the potential risk of publication bias. Meta-regression was used to explore potential sources of heterogeneity. RESULTS: We identified 130 studies reporting anxiety and depression among 132,068 medical students during the COVID-19 pandemic. Eight screening tools were identified for anxiety and six for depression. The pooled prevalence of mental health outcomes for anxiety and depression was 45% (95% confidence interval [CI], 40%-49%) and 48% (95% CI, 43%-52%), respectively. The pooled prevalence of mental health outcomes for moderate and severe anxiety and moderate and severe depression was 28% (95% CI, 24%-32%) and 30% (95% CI, 26%-35%), respectively. There was high heterogeneity between studies, with I2 ranging from 99.58%-99.66%. Continent and survey date were included in the meta-regression model. The results of meta-regression revealed that medical students in Asia had a lower prevalence of anxiety, and depression than those in other regions. The survey date (from February to June, 2020) showed a significantly positive correlation with the prevalence of anxiety and depression. CONCLUSIONS: We demonstrated the global prevalence of anxiety and depression among medical students during the COVID-19 pandemic. The data highlight that medical students worldwide are at high risk of experiencing anxiety and depression. The reported stressors can be categorized into personal, academic, environmental and cultural, and pandemic factors. Schools and institutions should ensure optimal alternative learning environments for uninterrupted provision of medical education. The appropriate authorities should prioritize the provision of adequate protection for medical students and establish policies to promote new methods of training and education during a disaster, such as via distance learning.

Empty toe: a unique type of closed degloving injury with dismal outcome.

Closed degloving injury is characterized by the development of soft tissue separated from underlying structure without outer skin disruption. "Empty toe" is one of the most unique types of closed degloving injuries. Only 4 such injuries have been reported previously. We demonstrate a case of this entity in a 20-year-old scooter passenger. She presented to our emergency department with apparent deformity of the left fifth toe with intact skin. Radiographic examination showed no skeletal fracture or dislocation, but the skin of the injured toe was detached from the underlying bony structure. Despite repositioning the phalangeal bone into the empty toe, the skin was nonviable, and surgical site gangrene developed thereafter. The fifth toe was eventually amputated. An empty toe implies that the injured site has experienced severe compressive and shearing force with potential neurovascular damage. Health care providers should be fully aware of the high risk of the probability of vascular insufficiency, and the viability would be associated with vascular capability.

Building an ethical environment improves patient privacy and satisfaction in the crowded emergency department: a quasi-experimental study.

BACKGROUND: To evaluate the effectiveness of a multifaceted intervention in improving emergency department (ED) patient privacy and satisfaction in the crowded ED setting. METHODS: A pre- and post-intervention study was conducted. A multifaceted intervention was implemented in a university-affiliated hospital ED. The intervention developed strategies to improve ED patient privacy and satisfaction, including redesigning the ED environment, process management, access control, and staff education and training, and encouraging ethics consultation. The effectiveness of the intervention was evaluated using patient surveys. Eligibility data were collected after the intervention and compared to data collected before the intervention. Differences in patient satisfaction and patient perception of privacy were adjusted for predefined covariates using multivariable ordinal logistic regression. RESULTS: Structured questionnaires were collected with 313 ED patients before the intervention and 341 ED patients after the intervention. There were no important covariate differences, except for treatment area, between the two groups. Significant improvements were observed in patient perception of "personal information overheard by others", being "seen by irrelevant persons", having "unintentionally heard inappropriate conversations from healthcare providers", and experiencing "providers' respect for my privacy". There was significant improvement in patient overall perception of privacy and satisfaction. There were statistically significant correlations between the intervention and patient overall perception of privacy and satisfaction on multivariable analysis. CONCLUSIONS: Significant improvements were achieved with an intervention. Patients perceived significantly more privacy and satisfaction in ED care after the intervention. We believe that these improvements were the result of major philosophical, administrative, and operational changes aimed at respecting both patient privacy and satisfaction.

Traumatic testicular dislocation: A case report and literature review.

INTRODUCTION: Traumatic testicular dislocation is an uncommon complication of blunt scrotal injury and is easily overlooked because of the presence of other severe accompanying injuries. In most cases, an operation is needed for the prevention of malignant change or infertility. PATIENT CONCERNS AND DIAGNOSIS: We report a case of traumatic testicular dislocation with pelvic fracture and internal bleeding in a 27-year-old male with testis rupture after a motorcycle collision. INTERVENTIONS AND OUTCOMES: He received emergent right radical orchiectomy, and a series of operations for femoral and pelvic fractures were performed after his condition stabilized in the intensive care unit. After 1 month postsurgery, no obvious genitourinary complications were noted. CONCLUSION: We suggest scrotum examination in all trauma patients, particularly if a pelvic injury is suspected or in case of a high risk of a motorcycle collision, to avoid missing the diagnosis and prevent severe complications.

The Relationship between Self-Perceived Health and Clinical Symptoms in Patients with Frozen Shoulders.

Current healthcare is centered on the perception of people's health. The purpose of this study was to investigate the relationship between self-perceived health (physical, psychological, social, and environmental dimensions) and two main clinical symptoms (shoulder pain and restricted shoulder motion) in patients with frozen shoulders. A total of 49 patients diagnosed with frozen shoulders were recruited and divided into high- and low-disability groups according to the severity of their frozen shoulders. Participants were measured for shoulder passive range of motion, pain intensity, and self-perceived health, using a brief version of the World Health Organization Quality of Life questionnaire. The results showed that the high-disability group had poorer self-perceived health (lower quality of life scores) than the low-disability group (p < 0.05). There was no significant correlation between the quality of life scores and the two clinical symptoms in either the high- or low-disability group. Our findings revealed that the multidimensional self-perceived health of frozen shoulder patients could not be inferred from the severity of shoulder pain and restricted shoulder motions. This study suggests that healthcare providers should pay more attention to patients' self-perceived health needs while addressing the clinical symptoms in patients with frozen shoulders.

Parental Educational Intervention to Facilitate Informed Consent for Pediatric Procedural Sedation in the Emergency Department: A Parallel-Group Randomized Controlled Trial.

Obtaining valid parental informed consent for pediatric procedures in the emergency department (ED) is challenging. We compared a video-assisted informed consent intervention with conventional discussion to inform parents about pediatric procedural sedation in the ED. We conducted a prospective randomized controlled trial using a convenience sample including the parents of children in the ED in whom procedural sedation for facial laceration was recommended. The video group watched an informational video. Conventional group participants received information from physicians during conventional discussion. The primary outcome was knowledge improvement of the video intervention compared with conventional discussion. The secondary outcome was parental satisfaction. Video and conventional groups comprised 32 and 30 participants, respectively. Mean knowledge scores of parents after intervention [±standard deviation] were higher in the video group (91.67 ± 12.70) than in the conventional group (73.33 ± 19.86). Knowledge score differences were significantly bigger in the video group (coefficient: 18.931, 95% confidence interval: 11.146-26.716). Video group participants reported greater satisfaction than conventional group participants. Parents' comprehension of and satisfaction with the informed consent process for pediatric procedural sedation may be improved with the use of an educational video. Standardized approaches should be developed by healthcare institutions to better educate parents, facilitate treatment decisions, and boost satisfaction in the ED.

Does COVID-19 Vaccination Cause Storage Lower Urinary Tract Symptoms?

We investigated the storage lower urinary tract symptoms (LUTS) before and after the first dose of coronavirus disease 2019 (COVID-19) vaccine and the association between pre-vaccinated overactive bladder (OAB) and the worsening of storage LUTS following COVID-19 vaccination. This cross-sectional study in a third-level hospital in Taiwan used the validated pre- and post-vaccinated Overactive Bladder Symptom Score (OABSS). Diagnosis of OAB was made using pre-vaccinated OABSS. The deterioration of storage LUTS was assessed as the increased score of OABSS following vaccination. Of 889 subjects, up to 13.4% experienced worsened storage LUTS after vaccination. OAB was significantly associated with an increased risk of worsening urinary urgency (p = 0.030), frequency (p = 0.027), and seeking medical assistance due to urinary adverse events (p < 0.001) after vaccination. The OAB group faced significantly greater changes in OABSS-urgency (p = 0.003), OABSS-frequency (p = 0.025), and total OABSS (p = 0.014) after vaccination compared to those observed in the non-OAB group. Multivariate regression revealed that pre-vaccinated OAB (p = 0.003) was a risk for the deterioration of storage LUTS. In conclusion, storage LUTS may deteriorate after vaccination. OAB was significantly associated with higher risk and greater changes in worsening storage LUTS. Storage LUTS should be closely monitored after COVID-19 vaccination, especially in those OAB patients.

Neck collar used in treatment of victims of urban motorcycle accidents: over- or underprotection?

BACKGROUND: Cervical collar brace protection of the cervical spine at the scene of the incident is the first priority for emergency medical technicians treating patients who have sustained trauma. However, there is still controversy between over- or underprotection. The objective of this study was to survey the cervical spine injury of lightweight motorcycle accident victims and further evaluate the neck collar protection policy. MATERIALS AND METHODS: We retrospectively reviewed patients who sustained lightweight motorcycle injuries, assumed to have been at a low velocity, with incidence of cervical spine damage, from a single medical center's trauma registration from 2008 to 2009. Patients were divided into 2 groups: those who were immobilized by cervical collar brace and those who were not. RESULTS: Of the 8633 motorcycle crash victims, 63 patients had cervical spine injury. The average of the injury severity score in these patients was 14.31 ± 8.25. There was no significant correlation of cervical spine injury between the patients who had had the neck collar applied and those who had not (χ(2), P = .896). The length of stay in intensive care unit was longer in the patients who had the neck collar applied, but the total hospital length of stay was not statistically different to the patients who did not have the neck collar applied. CONCLUSION: The incidence of cervical spinal injuries in the urban area lightweight motorcyclists is very low. Prehospital protocol for application of a cervical collar brace to people who have sustained a lightweight motorcycle accident in the urban area should be revised to avoid unnecessary restraint and possible complications.

Factors predicting patients' perception of privacy and satisfaction for emergency care.

STUDY OBJECTIVE: To identify emergency department (ED) predictors of patients' perception of privacy and whether patients' perception of privacy was significantly associated with patient satisfaction, in an urban, university-based hospital ED. METHODS: Patients' perceptions of privacy and satisfaction at one urban, university-based hospital ED were assessed. Structured questionnaires were performed, and measures for patients' perception of privacy and satisfaction as well as demographic data were included for data collection for each patient. Ordinal logistic regression model building was conducted for patients' perception of privacy. RESULTS: 364 patients were approached and 313 (86%) on-site questionnaires were completed. 75% of patients agreed and strongly agreed that privacy was very important for their emergency care. Factors that were highly correlated with patients' perception of privacy included personal information overheard by others (OR 0.6273), overhearing others' personal information (OR 0.5521), unintentionally heard inappropriate conversations from healthcare providers (OR 0.5992), being seen by irrelevant persons (OR 0.6337), space provided for privacy when being physically examined (OR 1.6091) and providers' respect for patients' privacy (OR 4.3455). Patient characteristics that significantly predicted lower ratings of perception of privacy included older age, the treatment area in a hallway and longer length of stay. Patient satisfaction was strongly predicted by the perception of privacy (OR 8.4545). CONCLUSION: These data identify specific factors that are determinants of patients' perception of privacy. It was found that patients' perception of privacy strongly predicts satisfaction. ED improvement efforts should focus on improving ED environmental design and continuing education of healthcare providers to protect patient privacy during their stay in the ED.

Combination of white blood cell count with liver enzymes in the diagnosis of blunt liver laceration.

BACKGROUND: It is sometimes difficult to decide whether to perform abdominal computed tomographic (CT) scans for possible liver laceration in patients who have sustained less severe or minor blunt abdominal trauma. This study was conducted to find out whether the basic laboratory workup could provide information of possible liver laceration in blunt abdominal trauma patients and act as an indication for CT scans. METHODS: In this retrospective case-control study, we included 289 patients who had sustained blunt abdominal injury for which they received abdominal CT scans in our emergency department. Of the 289 patients, the study group (n = 42) included patients who had been found to have liver lacerations after obtaining the CT; the controls (n = 42) were those not found to have such injuries by the same method with matching of age and sex. RESULTS: In patients with blunt abdominal injuries, there is a strong difference in liver laceration between elevation of white blood cell (WBC) counts (P = .001), aspartate aminotransferase (AST) (P < .001), and alanine aminotransferase (ALT) (P < .001). A logistic regression model demonstrated that WBC count and AST were independently associated with liver laceration. With elevations of serum AST greater than 100 IU/L, ALT greater than 80 IU/L, and WBC count greater than 10 000/mm(3), we found a sensitivity and specificity of 90.0% and 92.3%, respectively, in the 42 liver laceration victims. CONCLUSION: In patients with blunt abdominal trauma, elevated WBC counts together with elevated AST and ALT are strongly associated with liver laceration and warrant further imaging studies and management.

Management of motorcycle accident-related blunt hepatic injury-a different strategy.

BACKGROUND: In motorcycle accidents, especially in an urban area with lightweight motorcycles, the belly of the motorcyclist is not protected, and this makes this type of trauma a cause of blunt hepatic injuries. This study investigated the effect and safety of using nonoperative management and selective early angioembolization to treat patients with blunt liver injuries as a result of motorcycle accident. METHODS: This was a retrospective study of the hepatic injuries sustained by motorcyclists involved in traffic accidents. We collected patient demographic information, the severity of total injuries, grade of liver injury, associated concomitant injuries, management scheme, and outcome of patients from 2006 to 2007. These patients were treated nonoperatively with selective early angioembolization and close monitoring in our intensive care unit (ICU). RESULTS: We reviewed the cases of 266 patients sustaining blunt abdominal injuries. Thirty-four patients (12.78%) had hepatic injuries. All survived with no obvious morbidity, and no further invasive procedures were performed after admission to ICU. There was no significant association between grade of injury and ICU length of stay (P = .073), but there was a significant association between grade and in-patient length of stay on our regular ward (P = .001). CONCLUSION: Most patients with hepatic injury caused by motorcycle accidents can be treated safely by nonoperative management. Early selective angioembolization improved the success of nonoperative management of blunt liver injury without other surgical intervention. Routine follow-up with computed axial tomography scans and endoscopic retrograde cholangiopancreatography may not be necessary because complications associated with hepatic injuries were rare.

Inflammatory omental cyst adjacent to the transverse colon mimicking appendicitis in an adult patient.

Cysts of the omentum are rare and most frequently discovered in children. These cysts may cause abdominal distension, pain, or vomiting. Omental cysts with right lower quadrant pain are found even more rarely in adults. We describe a 44-year-old male who had a 2-day history of abdominal pain localized in the right lower quadrant. Before surgery, acute appendicitis with intra-abdominal abscess was suspected, but during the operation, an infected cyst of the omentum, adjacent and adherent to the redundant transverse colon, was found to have been causing these symptoms. Despite the fact that cysts of the omentum have been reported rarely, the operator should be aware that the cyst is a benign entity and the surgical strategy should be different from that for malignancy. We should keep the possibility of omental cyst in mind to avoid unnecessary bowel resection and potentially harmful inappropriate treatment.

Damage control in the transection of carotid artery--a case report.

Transection of the carotid artery is very rare in Taiwan owing to tight gun control. Most carotid artery injuries are caused by penetration wounds as a result of stabbing or shooting. The total transection of internal and external common arteries is very rarely encountered, and most surgeons lack experience of this intervention. We present a very rare patient who had his right neck cut caused by a flying piece of sheet metal during a typhoon. The case was sent to our emergency department without any vital signs. Intubation was performed into the perforation of larynx with aggressive resuscitation. The patient regained his heart rate and blood pressure after several minutes of cardiopulmonary resuscitation. Then he was sent to operating room, where tracheostomy was performed and bleeding was controlled by ligation of all bleeding arteries including internal and external carotid arteries. Two days later, the patient died, however. We reviewed the literatures and discussed the case.

Pancreatic tail cancer with sole manifestation of left flank pain: a very rare presentation.

Pancreatic cancer is sometimes called a "silent disease" because it often causes no symptoms in the early stage. The symptoms can be quite vague and various depending on the location of cancer in the pancreas. The anatomic site distribution is 78% in the head of the pancreas, 11% in the body, and 11% in the tail. Pancreatic cancer is rarely detected in the early stage, and it is very uncommon to diagnose pancreatic tail cancer during an emergency department visit. The manifestation of pancreatic tail cancer as left flank pain is very rare and has seldom been identified in the literature. We present a case of pancreatic tail cancer with the sole manifestation of dull left flank pain. Having negative findings on an ultrasound study initially, this female patient was misdiagnosed as having possible acute gastritis, urolithiasis or muscle strain after she received gastroendoscopy and colonofiberscopy. Her symptoms persisted for several months and she visited our emergency department due to an acute exacerbation of a persistent dull pain in the left flank area. Radiographic evaluation with computed tomography was performed, and pancreatic tail tumor with multiple metastases was found unexpectedly. We review the literature and discuss this rare presentation of pancreatic tail cancer.
