Gastritis cystica profunda (GCP) consists of hyperplasia and cystic dilatation of the gastric glands extending into the submucosa. It occurs in the residual stomach post surgery and in the unoperated stomach. GCP is considered a benign lesion, but there is controversy about its malignant potential. We report a case of early gastric cancer arising from GCP treated by endoscopic submucosal dissection (ESD) in a 55-year-old unoperated man. Upper gastrointestinal endoscopy revealed a 15-mm diameter submucosal tumor (SMT) in the upper corpus of the stomach. The surface had angiotelectasia and slight depression covered with normal mucosa. Neither ulceration nor erosion was seen. Narrow-band imaging endoscopy showed no abnormalities suggesting gastric cancer. Endoscopic ultrasonography visualized the internally low-echoic SMT, harboring tiny cystic lesions, mainly within the second and third layers of the gastric wall. The SMT was removed by ESD to avoid retention and allow for comprehensive diagnosis. It was diagnosed as GCP with partial well-differentiated adenocarcinoma without involvement of the lateral and deep margins, lymphatic invasion, vascular invasion and perineural invasion. The gastric epithelium comprised normal mucosa without dysplasia. ESD seems to be useful for the diagnosis of SMT, including GCP harboring gastric cancer, and avoids unnecessary surgical procedures.
Rotational thromboelastometry (ROTEM), known as point-of-care testing, has been incorporated into various kinds of postsurgical management. However, the utility of ROTEM for rapid diagnosis of sepsis-induced disseminated intravascular coagulation (DIC) has not been investigated. This retrospective study includes 13 sepsis patients who underwent ROTEM in our emergency department in 2013. All patients were divided into two groups on the basis of the presence of DIC diagnosed by the Japanese Association for Acute Medicine (JAAM) DIC score. We evaluated the demographics, clinical characteristics, laboratory data, ROTEM test and outcomes for each patient. The correlations between JAAM DIC score and significantly different parameters by univariate analysis and receiver operating characteristic (ROC) analysis were performed to assess the accuracy of the variables. There were seven and six patients in the DIC group and non-DIC group, respectively. The DIC group showed significantly longer prothrombin times, international normalized ratio of prothrombin time and clotting times (CTs) in the EXTEM test, and higher fibrinogen and fibrin degradation products and D-dimer. The CT in EXTEM test was correlated more with JAAM DIC score (r = 0.798), than the standard coagulation test. These parameters were accurate predictors in the diagnosis of septic DIC, with an AUC of 0.952, and a cut-off value of more than 46.0 s, resulting in a sensitivity of 100.0% and a specificity of 83.3%. CT in the EXTEM test was a single reliable indicator of sepsis-induced DIC diagnosed by the JAAM DIC score, and strongly associated with severity of DIC.
Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy.
It is well known that coagulopathy is observed in patients with out-of-hospital cardiac arrest (OHCA). Thrombolytic therapy for those patients has been controversial until now. The purpose of this study was to identify a significant predictor for return of spontaneous circulation (ROSC) of OHCA patients in the emergency department (ED) using whole blood viscoelastic testing. Adult non-trauma OHCA patients transported to our hospital that underwent thromboelastometry (ROTEM) during cardiopulmonary resuscitation between January 2013 and December 2015 were enrolled in this study. We divided patients into two groups based on the presence or absence of ROSC, and performed statistical analysis utilizing patient characteristics, prehospital data, laboratory data, and ROTEM data. Seventy-five patients were enrolled. The ROSC group and non-ROSC group included 23 and 52 patients, respectively. The logistic regression analysis, utilizing significant parameters by univariate analysis, demonstrated that lactate level [odds ratio (OR) 0.880, 95% confidence interval (CI) 0.785–0.986, p = 0.028] and A30 of EXTEM test [OR 1.039, 95% CI 1.010–1.070, p = 0.009] were independent risk factors for ROSC. The cut-off values of lactate and A30 in EXTEM were 12.0 mmol/L and A 48.0 mm, respectively. We defined a positive prediction for ROSC if the patient presented lower lactate level (<12.0 mmol/L) and higher A30 of EXTEM (≥48.0 mm) with high specificity (94.7%) and accuracy (75.0%). The present study showed that lactate level and ROTEM parameter of clot firmness were reliable predictors of ROSC in the ED for adult patients with OHCA.
In this project, a “Disaster Management Literacy Hub” (DMLH) has been developed for collecting, creating, and transmitting various disaster management content over the Internet. The first screen of the DMLH lists disaster management content on tiles to allow users easily find relevant disaster management content using a keyword retrieval function. A user who registers an account can post disaster management content, create a first screen that is customized using the “favorite function,” and compile different disaster management content using the “binder function.” In addition to the “relay (hub) function” for disaster management content, a “creation function” was also implemented, such as the “message function” for posting short messages of approximately 200 letters and an image, and the “quiz creation function” for measuring the effects of disaster management literacy. In the course of modifying the prototype Disaster Management Literacy Hub, the system was evaluated by university student users in July 2016, approximately one year after the fully-fledged operation came into effect in August 2015. The results yielded the following findings: 1) the DMLH is meaningful because by using specific keywords, users retrieved items that had been difficult to find by means of general Internet search sites; 2) statistically significant improvement was shown for 15 disaster management literacy items in the evaluation; the DMLH leads to a proposal to create effective disaster management literacy improvement because students recognized three disaster management literacy categories: cases of disasters and disaster management, responses of familiar agents such as themselves and people to one, and responses of agents in the environment, including local communities and governments.
Few studies have investigated deployment-related experiences of healthcare workers dispatched for medical humanitarian aid or attempted to assess their difficult living and working environments. This is the first study to develop and validate a scale to measure these kinds of difficulties, in 264 Japanese healthcare workers. The Humanitarian Aid Difficulty Scale was developed in three stages. First, an item pool was generated based on literature and expert reviews. The scale was then tested in a pilot study. Reliability and validity were identified through exploratory and confirmatory factor analysis and Cronbach's alpha. The scale consisted of 23 items across five factors based on exploratory factor analysis (cooperation, health status, infrastructure, culture and customs, and supplies and equipment). The total variance explained was 60.7%. Reliability of the five factors was acceptable and validity was supported by confirmatory factor analysis. Cronbach's alpha for the scale was 0.87. The scale may enable evaluation of the level of difficulty of the living and working environments of Japanese healthcare workers in medical humanitarian aid who are at a greater risk of distress.
