Nephroblastomatosis (NBM) is a precursor of Wilms tumor. We herein report a case in which Wilms tumor was initially suspected and the affected kidney was removed.The tumor was subsequently diagnosed as intralobar NBM and a favorable outcome was achieved with postoperative chemotherapy. A 2-year-old boy who presented with gross hematuria was found to have an enlarged left kidney with hydronephrosis.Needle biopsy of the left kidney suggested Wilms tumor and left nephrectomy was performed. The tumor was histopathologically diagnosed as intralobar NBM.Although NBM is regarded as a precancerous lesion, a definite treatment plan has not yet been established. In the present case, we used a similar chemotherapy regimen to that for Wilms tumor. Eight years after the completion of chemotherapy, Wilms tumor has not developed or recurred. Appropriate management plans need to be developed by accumulating similar cases.

Vertebral fractures occur with only slight trauma in patients with diffuse idiopathic skeletal hyperostosis (DISH). However, a lumbar vertebra fracture, due to an intraoperative body position has not been previously reported. An 87-year-old woman with kyphosis sustained a left trochanteric fracture of her femur. The patient was placed in a supine position during the operation. Postoperatively, the patient experienced severe right thigh pain. Magnetic resonance imaging revealed an L4 vertebral fracture. Computed tomography revealed ankylosis from the upper thoracic spine to the sacrum. While in a supine position under general anesthesia, the contact of the patient's lower back with operating table likely created a fulcrum at her lumbosacral spine acting as a long lever arm, bearing the mass of her upper body. We performed L1-S2 posterior stabilization. DISH patients with kyphosis placed in a supine position have an increased risk for lumbar vertebral fracture.

An 82-year-old woman was transferred to our hospital due to an abrupt back pain. She exhibited a cardiac tamponade and her CT angiography revealed Stanford type-A acute aortic dissection without abdominal extension. Emergent surgery for partial arch replacement was performed. After a few days of stable postoperative course, she suffered 38 degrees fever with an elevated inflammatory response and complained of a slight abdominal pain. Her CT scan revealed an intra-abdominal abscess with a small intestine necrosis. Emergent surgery for partial small intestine resection was performed. Her postoperative course was stable and she was discharged to a rehabilitation hospital 52 days after the first operation.

Non-occlusive mesenteric ischemia (NOMI) after cardiovascular surgery is a disease with a poor prognosis that is difficult to diagnose and treat. We report a case of NOMI diagnosed and treated immediately after open heart surgery. A 77-year-old man was admitted to our hospital due to heart failure. Echocardiography showed the diagnosis of severe aortic stenosis. He underwent surgery for the replacement of the aortic valve. After surgery, the hemodynamics became unstable and lactate continued to rise. Contrast abdominal computed tomography revealed a smaller SMV sign and ischemic area in the intestinal wall. We suspected NOMI, and continuous intravenous administration of prostaglandin was started. Angiography revealed scattered vascular stenosis in the superior and inferior mesenteric arteries, which led to the diagnosis of NOMI, and selective infusion of papaverine hydrochloride was started. Thereafter, hemodynamic improvement was observed and the patient was able to survive. To facilitate early diagnosis and treatment of NOMI, it is important to establish a protocol at the time of onset of illness to ensure smooth treatment.

Abstract
A large rubella epidemic is currently ongoing since 2018 in Osaka, Japan. The detected rubella viruses were classified into genotypes 1E lineage 2 and 2B lineage 1. These strains may have been imported from endemic countries, and these viruses spread within the susceptible population.

Introduction: Research was carried out using a mixed method approach in order to evaluate the educational effects of medical students' visit of an elderly home.Methods: Focus group interviews were conducted with 5 medical students and 5 elderlies. All interviewees had experienced the visitation program more than three times. Self-administrative questionnaires were built based on the results of the focus group interview. The questionnaire was then distributed to medical students and elderlies who participated in the program.Results: A total of 84 medical students and 30 elderlies provided informed consent to participate in the study and returned the questionnaire. Nearly 70 percent of the students answered that they had gotten to know about the life of elderly people and sixty percent of the elderlies answered they had experienced some favorable changes after joining the program. While ninety percent of the elderly were satisfied with the program, only half of the students showed positive comments toward it.Discussion: To help all students participate in this program more actively, more organized planning is necessary so that students can have more chances to build communication skills and clarify their own objectives when visiting the elderly.
