A 2-month-old male infant was transferred to our hospital for suspected cardiomyopathy because he had livedo reticularis and peripheral coldness. An electrocardiogram showed ischemic change and an echocardiogram showed a dilated, poorly functioning left ventricle. Therefore, we performed urgent cardiac catheterization. The coronary artery was not visualized by aortography, but the single coronary artery arising from the pulmonary artery was depicted by pulmonary angiography. Therefore, we performed emergent surgery. The whole coronary arteries traveled directly inferiorly from the left side of the pulmonary trunk. A patent ductus arteriosus (PDA) was closed at the operation. We established cardiopulmonary bypass using two arterial cannulae through both ascending aortas and pulmonary trunk to maintain coronary blood flow. Direct implantation is difficult because the coronary ostium is far from the ascending aorta. Therefore, we chose to perform the Takeuchi procedure using an intrapulmonary artery tunnel. The patient's postoperative course was good, and he was discharged on postoperative day 22. A case of an anomalous origin of a single coronary artery from the pulmonary artery without any other heart disease is extremely rare. Management of cardiopulmonary bypass and myocardial protection in this abnormality is discussed.

To screen for additional treatment targets against tongue cancer, we evaluated the contributions of extracellular signal-related kinase (ERK), AKT and ezrin in cancer development. Immunohistochemical staining showed that ERK and ezrin expressions were significantly higher in invasive squamous cell carcinoma than in carcinoma in situ. To investigate the roles of ERK and ezrin in cancer development, we used the non-woven silica fibre sheet Cellbed with a structure resembling the loose connective tissue morphology in a novel 3D culture system. We confirmed that the 3D system using Cellbed accurately mimicked cancer cell morphology in vivo. Furthermore, cell projections were much more apparent in 3D-cultured tongue cancer cell lines than in 2D cultures. Typically, under conventional 2D culture conditions, F-actin and cortactin are colocalized in the form of puncta within cells. However, in the 3D-cultured cells, colocalization was mainly observed at the cell margins, including the projections. Projections containing F-actin and cortactin colocalization were predicted to be invadopodia. Although suppressing ezrin expression with small interfering RNA transfection caused no marked changes in morphology, cell projection formation was decreased, and the tumour thickness in vertical sections after 3D culture was markedly decreased after suppressing ERK activity because both the invasion ability and proliferation were inhibited. An association between cortactin activation as well as ERK activity and invadopodia formation was detected. Our novel 3D culture systems using Cellbed™ are simple and useful for in vitro studies before conducting animal experiments. ERK contributes to tongue cancer development by increasing both cancer cell proliferation and migration via cortactin activation.

BACKGROUND:
To examine changes in psychological distress prevalence among pregnant women in Miyagi Prefecture, which was directly affected by the Great East Japan Earthquake and tsunami, and compare it with the other, less damaged areas of Japan.
METHODS:
This study was conducted in conjunction with the Japan Environment and Children`s Study. We examined 76,152 pregnant women including 8270 in Miyagi Regional Center and 67,882 in 13 other regional centers from the all-birth fixed data of the Japan Environment and Children's Study. We then compared the prevalence and risk of distress in women in Miyagi Regional Center and women in the 13 regional centers for 3 years after the disaster.
RESULTS:
Women in the Miyagi Regional Center suffered more psychological distress than those in the 13 regional centers: OR 1.38 (95% CI, 1.03-1.87) to 1.92 (95% CI, 1.42-2.60). Additionally, women in the inland area had a consistently higher prevalence of psychological distress compared to those from the 13 regional centers: OR 1.67 (95% CI, 1.18-2.38) to 2.19 (95% CI, 1.60-2.99).
CONCLUSIONS
The lack of pre-disaster data in the Japan Environment and Children's Study made it impossible to compare the incidence of psychological distress before and after the March 2011 Great East Japan Earthquake. However, 3 years after the Great East Japan Earthquake, the prevalence of pregnant women with psychological distress did not improve in Miyagi Regional Center. Further, the prevalence of mental illness in inland areas was consistently higher than that in the 13 regional centers after the disaster.
