Cardiac papillary fibroelastoma (PFE) is a benign cardiac tumor that mainly occurs in the valve leaflets of the left heart. The patient was a 72-year-old man diagnosed with cerebral infarction. Contrast-enhanced computed tomography and transesophageal echocardiography revealed a 12-mm mass in the left atrial appendage (LAA), and we decided to undergo emergency cardiac tumor resection due to embolism onset. Postoperative pathological examination revealed an extremely rare cardiac PFE originating in the LAA.

BACKGROUND:
Chronic constipation is a long-term problem that decreases children's quality of life. Information and communication technology devices have developed rapidly in recent decades and have had various impacts on children. This prospective cohort study examined the association between television/digital versatile disc (TV/DVD) screen exposure time at age 1 and the risk of chronic constipation at age 3.
METHODS:
Data from 63,697 infants in the Japan Environment and Children's Study (JECS) were analyzed. We divided participants into five groups according to TV/DVD exposure time per day: no exposure (0 h), short exposure (<1 h), middle exposure (1.0-<2.0 h), long exposure (2.0-<4.0 h), and very long exposure (≥4 h). Logistic regression analysis was performed to assess the association between TV/DVD exposure time and the risk of constipation. For logistic regression analysis, odds ratios (ORs) were adjusted for sex, parents' education, household income, nursery school, feeding contents, and obesity. The interaction between the sexes was also examined.
RESULTS:
The prevalence of constipation for males, females, and all participants at age 3 was 9.3, 11.0, and 10.1%, respectively. The TV/DVD screen time distribution per day at age 1 was 10.6% for none, 34.1% for short, 29.9% for middle, 19.2% for long, and 6.2% for the very long exposure group. After adjusting for confounding factors, a dose-response pattern was identified between TV/DVD exposure time and constipation in all participants (p for trend < 0.001). The adjusted ORs increased progressively in the short (OR 1.15, 95% confidence interval [CI] 1.04-1.27), middle (OR 1.22, 95% CI 1.11-1.35), long (OR 1.37, 95% CI 1.24-1.52), and very long exposure groups (OR 1.53, 95% CI 1.35-1.74). This association was not significantly different between the sexes (p for interaction = 0.36).
CONCLUSIONS
Longer TV/DVD exposure time at age 1 was associated with the risk of chronic constipation at age 3. Excessive screen exposure may need to be avoided from infancy to decrease the risk of chronic constipation in later years.

Integrated Distress Activity Score (IDAS) was developed in order to evaluate both positive and negative aspects of patient’s conditions throughout hospitalization. IDAS were evaluated by nurses everyday and when patients continued to have IDAS less than or equal to zero, we used this tool for determining continuous deep sedation. From 2013-2017, 1306 patients were enrolled in the study. The average rate of continuous deep sedation in the PCU was 1.2%(16 patients). Dyspnea was the most common condition (62.5%, 10 patients), followed by delirium (37.5%, 6 patients).The average days that took to decide for sedation (from the day when IDAS was less than or equal to zero), was 3.7 days. This study suggested that IDAS could be a useful tool for determining continuous deep sedation.

Undergraduate medical students in their 5th year were given integrated lectures on two topics, “ The cerebellum ” and “Patient -centered medical care”. The results of a questionaire survey indicated that students had hoped for continuation and expansion of the lectures to include many other topics. A series of discussions among faculty however, disclosed two problems with regard to continuation and expansion, i. e., a lack of experts for integration and lack of adequate means to assess educational impact. Teaching personnel in integrated lectures need not necessarily be experts or professors, but persons who can be in close contact with one another for the purpose of integration. Setting aside rigid discussions on validity, small achievement tests may be useful in assessing the degree of student comprehension.
