This study examines the influence of familiarity on witnesses’ memory and the individual effectiveness of each of the four cognitive interview instructions in improving witnesses’ recall of scripted events. Participants (N = 195), either familiar or unfamiliar with the hospital script, were presented with a video of a surgical operation. One week later, an interviewer used one of the four cognitive interview instructions or a control instruction to ask them about the video. Participants familiar with the surgery context recalled significantly more correct information and, in particular, more consistent and irrelevant details than those unfamiliar with the surgery context. Furthermore, the results confirmed the effectiveness of all four cognitive interview mnemonics in enhancing the amount of correct information reported, irrespective of the participants’ familiarity with the critical event. However, their efficacy differed depending on the category of details considered. The practical implications of these results are discussed.

Clinicopathological Significance

Abstract Background Certain gastric cancers exhibit some primitive phenotypes, which may indicate a high malignancy. In histologically differentiated early gastric cancer (EGC), the presence and the clinicopathological significance of the primitive phenotype remain unclear. Methods Using immunohistochemical staining we detected the expression of three primitive phenotypic markers SALL4, Glypican-3(GPC3), and AFP in whole tissue sections of differentiated EGC (gastrectomy specimens, n = 302). For those cases with primitive phenotypes, we analyzed their clinicopathological features and evaluated whether the criteria for endoscopic resection were met. Results We found that 9.3% (28/302) of all differentiated EGC cases have primitive phenotypes, and most of these cases (25/28) exhibit a histomorphology similar to conventional differentiated EGC. Patients with primitive phenotypes had a deeper invasion, a higher rate of ulcer and lymphatic invasion than cases without primitive phenotype. Moreover, patients with primitive phenotypes displayed a significantly higher frequency of LNM than those without (57.1% vs 8.8%, P < 0.001). Multivariate analysis revealed that presence of primitive phenotypes was an independent risk factor for LNM (P = 0.001, HR 6.977, 95% CI: 2.199–22.138). Interestingly, we found 2 cases with primitive phenotypes developed LNM, and they both met the expanded indications of endoscopic resection for differentiated EGC. Conclusions A small number of differentiated EGC have primitive phenotypes, which were closely related to LNM and were an independent risk factor for LNM. Given its highly aggressive behavior, differentiated EGC with primitive phenotypes should be evaluated with stricter criteria before endoscopic resection, or considered to give an additional surgical operation after endoscopic resection.

On a baby girl of 4 weeks old with the dtagnosts of congenital hypertrophic pyloric stenosis, an extremely rare case in our Hospital, surgical operation was done using the Fredet Ramsted method. The main complaint was frequent vomiting. The diagnosis was based on projectile vomiting, retarded growth, constipation, moderate dehydration and was confirmed by barium meal study. Ten days after the operation, she was discharged in a good condition.

Heart Lesions

Heart trauma is a severe form of thoracic trauma with an incidence of 7–14%. Heart trauma can be either open or blunt, with the latter more prevalent during a disaster. Possible open heart injuries include: (1) pericardial injuries; (2) superficial myocardial and coronary vessels injuries; and (3) penetrating cardiac wounds. The variants of blunt heart trauma include: (1) heart concussion and contusion; (2) rupture of the heart wall and intracardiac structures; (3) rupture of cusps and cords of the heart valves; and (4) cardiac septa (i.e., post-traumatic heart lesions). The latter are characteristic of injuries caused by a fall, and/or a crushing event. The course of heart trauma is severe, and is complicated by the development of shock and catastrophic hemodynamic disorders due to the sudden occurrence of post-traumatic heart lesions and infarction. Thus, verifying cardiac trauma can be complicated. Diagnosing and assessing the severity of heart trauma requires the measurement of intra-arterial and central venous pressures, chest radiography, electrocardiography, pericardial puncture, echocardiography, magnetic resonance imaging, cardioangiography, and measurement of heart enzymes. One-hundred twenty-seven patients ages 2 to 42 years with open (92.1%) and blunt (7.9%) cardiac trauma were treated. Of these patients, 16.5% were children and teenagers. The challenges of treating heart trauma include simultaneously carrying out anti-shock treatment, surgical operation, and resuscitation measures. If post-traumatic heart lesions are diagnosed, surgical correction should be performed despite cardiac decompression. The use of cardiopulmonary bypass is essential.
