PURPOSE: Pancreatic injury is rare in abdominal trauma patients (3%~12%). but it could result in significant morbidity and even mortality. Early and adequate decision making are very important in the management of patients with traumatic pancreatic injury. The purpose of this study was to assess the kinds of management and outcome through the review of our experience of pancreatic injury with multiple trauma. METHODS: We reviewed 17 patients with traumatic pancreas injury via electronic medical records from Jan. 2002 and April. 2011. We collected demographic findings; the type, location and grade of pancreas injury, the treatment modality, and patient's outcomes, such as complications, length of hospital stay (LOS), and mortality. RESULTS: Total 17 patients were reviewed, and man was 13 (88%). Traffic accident was the most common cause of injury. Pancreas neck was the most common injured site, and occured in 5 patients. Ductal injury was detected in 7 cases. Eleven patients were treated by surgical procedure, and in this group, 3 patients underwent the endoscopic retrograde pancreas drainage procedure coincidently. ERPD was tried in 8 patients, and failed in 2 patients. The major complications were post-traumatic fluid collection and abscess which accounted for 70% of all patients. The hospital stay was 35.9 days, and it was longer in patient with ductal injury (38.0+/-18.56 vs. 34.5+/-33.68 days). Only one patient was died due to septic shock associated with an uncontrolled retroperitoneal abscess. CONCLUSION: Early diagnosis is the most important factor to apply the adequate treatment option and to manage the traumatic pancreas injury. Aggressive treatment should be considered in patients with a post-operative abscess.

PURPOSE: We wanted to describe the characteristics of the malpractice claims related to acute appendicitis and to identify medico-legal problems and potential preventability of such claims. METHODS: A retrospective study was performed by reviewing the records at websites that furnishes judicial precedents. The records on closed malpractice claims involving acute appendicitis were abstracted from the files that were available for analysis. The records were reviewed and analyzed to determine the causes of the lawsuits, the pre- and post-operative diagnoses, the comorbid conditions of the patient, the causes of death or post-operative complications, the results of the lawsuits and the factors associated with a successful defense. RESULTS: Twelve closed claims involving acute appendicitis were founded in the malpractice data. Two claims were Supreme Court decisions and ten were district court decisions. The causes of lawsuit were categorized as follows: delay in diagnosis or operation, mistakes during operation, inappropriate management of postoperative complications and problems related to general anesthesia. 3 claims were assigned to each of the 4 particular causes of lawsuits. The most common causes of death were abscess with peritonitis and sepsis, and ten of which resulted in indemnity payments. CONCLUSION: Appropriate explanation and attention in the diagnosis/progress of appendicitis, getting an informed consent from the patient, the patients' comorbid conditions, early decision making in diagnosis/operation and proper care in the operation were critical for preventing lawsuits related to acute appendicitis.

Background: As the number of large-scale studies involving multiple organizations producing data has steadily increased, an integrated system for a common interoperable format is needed. In response to the coronavirus disease 2019 (COVID-19) pandemic, a number of global efforts are underway to develop vaccines and therapeutics. We are therefore observing an explosion in the proliferation of COVID-19 data, and interoperability is highly requested in multiple institutions participating simultaneously in COVID-19 pandemic research. Results: In this study, a laboratory information management system (LIMS) approach has been adopted to systemically manage various COVID-19 non-clinical trial data, including mortality, clinical signs, body weight, body temperature, organ weights, viral titer (viral replication and viral RNA), and multiorgan histopathology, from multiple institutions based on a web interface. The main aim of the implemented system is to integrate, standardize, and organize data collected from laboratories in multiple institutes for COVID-19 non-clinical efficacy testings. Six animal biosafety level 3 institutions proved the feasibility of our system. Substantial benefits were shown by maximizing collaborative high-quality non-clinical research. Conclusions This LIMS platform can be used for future outbreaks, leading to accelerated medical product development through the systematic management of extensive data from non-clinical animal studies.

Viral load and the duration of viral shedding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are important determinants of the transmission of coronavirus disease 2019.In this study, we examined the effects of viral doses on the lung and spleen of K18-hACE2 transgenic mice by temporal histological and transcriptional analyses. Approximately, 1×105 plaque-forming units (PFU) of SARS-CoV-2 induced strong host responses in the lungs from 2 days post inoculation (dpi) which did not recover until the mice died, whereas responses to the virus were obvious at 5 days, recovering to the basal state by 14 dpi at 1×102 PFU. Further, flow cytometry showed that number of CD8+ T cells continuously increased in 1×102 PFU-virusinfected lungs from 2 dpi, but not in 1×105 PFU-virus-infected lungs. In spleens, responses to the virus were prominent from 2 dpi, and number of B cells was significantly decreased at 1×105PFU; however, 1×102 PFU of virus induced very weak responses from 2 dpi which recovered by 10 dpi. Although the defense responses returned to normal and the mice survived, lung histology showed evidence of fibrosis, suggesting sequelae of SARS-CoV-2 infection. Our findings indicate that specific effectors of the immune response in the lung and spleen were either increased or depleted in response to doses of SARS-CoV-2. This study demonstrated that the response of local and systemic immune effectors to a viral infection varies with viral dose, which either exacerbates the severity of the infection or accelerates its elimination.
