Non-alcoholic fatty liver disease is currently the most common chronic liver disease, affecting up to 25% of the global population. Simple fatty liver, in which fat is deposited in the liver without fibrosis, has been regarded as a benign disease in the past, but it is now known to be prognostic. In the future, more emphasis should be placed on the quantification of liver fat. Traditionally, fatty liver has been assessed by histological evaluation, which requires an invasive examination; however, technological innovations have made it possible to evaluate fatty liver by non-invasive imaging methods, such as ultrasonography, computed tomography, and magnetic resonance imaging. In addition, quantitative as well as qualitative measurements for the detection of fatty liver have become available. In this review, we summarize the currently used qualitative evaluations of fatty liver and discuss quantitative evaluations that are expected to further develop in the future.

With advances in cancer treatment, such as cytotoxic chemotherapy and radiotherapy, grave new sequelae of treatment have emerged for young cancer survivors. One sequela that cannot be overlooked is male infertility, with reportedly 15% to 30% of cancer survivors losing their fertility potential. Cytotoxic therapy influences spermatogenesis at least temporarily, and in some cases, permanently. The degree of spermatogenesis impairment depends on the combination of drugs used, their cumulative dose, and the level of radiation. The American Society of Clinical Oncology has created an index to classify the risks to fertility based on treatment. Medical professionals currently use this risk classification in fertility preservation (FP) programs. FP programs are currently being promoted to prevent spermatogenesis failure resulting from cancer treatment. For patients who are able to ejaculate and whose semen contains sperm, the semen (sperm) is cryopreserved. Moreover, for patients who lack the ability to ejaculate, those with azoospermia or severe oligozoospermia, and those who have not attained puberty (i.e., spermatogenesis has not begun), testicular biopsy is performed to collect the sperm or germ cells and cryopreserve them. This method of culturing germ cells to differentiate the sperm has been successful in some animal models, but not in humans. FP has recently gained popularity; however, some oncologists and medical professionals involved in cancer treatment still lack adequate knowledge of these procedures. This hinders the dissemination of information to patients and the execution of FP. Information sharing and collaboration between reproductive medicine specialists and oncologists is extremely important for the development of FP. In Japan, the network of clinics and hospitals that support FP is expanding across prefectures.

In our hospital, we typically perform laparoscopic partial gastrectomy as surgical treatment for extragastric growth type of submucosal tumor (SMT), and laparoscopic intragastric surgery for intragastric growth type. In 2008, laparoscopic and endoscopic cooperative surgery (LECS) was reported for the first time by Hiki et al. Against the background of LECS as laparoscopic local gastric resection with endoscopic resection, we started LECS for gastric SMT from 2015. 　　We performed laparoscopic (LAP) surgery for 15 gastric SMT cases from 2009, and compared 5 cases for which LECS was performed and 10 cases for which LAP was performed. Tumor diameter was 15–21 mm (mean 19.2 mm) in the LECS group, and 20–53 mm (mean 35.5 mm) in the LAP group; the LECS group had a significantly smaller tumor diameter. Operative time was 299 ± 45 min in LECS and 222 ± 25 min in LAP. The volume of blood loss was 24 ± 13 mL in LECS and 33 ± 13 mL in LAP. Hospitalization days was 14.0 ± 3.0 days in LECS and 12.9 ±0.8 days in LAP. There was no significant difference between them.

We report here 2 cases of traumatic diaphragmatic hernia. Case 1 was a 76-year-old man who was injured in a road traffic accident (RTA). Chest X-ray and computed tomography (CT) revealed prolapse of the stomach into the left thoracic cavity. We performed laparotomy with a diagnosis of traumatic left diaphragmatic hernia. A 12-cm hole was seen in the central tendon of the left diaphragm and this was repaired by suturing. Case 2 was a 75-year-old man who was also injured in an RTA. Chest X-ray and CT revealed prolapse of the stomach and transverse colon into the left thoracic cavity. We performed laparotomy with a diagnosis of traumatic left diaphragmatic hernia. A 15-cm hole was seen in the central tendon of the left diaphragm and this was repaired by suturing. Traumatic diaphragmatic hernia is a relatively rare condition and one that requires surgical repair. It is important to make prompt diagnosis with appropriate radiological investigations. Additionally, patients with diaphragm hernia caused by blunt trauma often have injuries to other organs. Care should be taken so as not to miss associated injuries.

Introduction: Attention to undergraduate medical education on the relationship between physicians and the pharmaceutical industry has been increasing in North America and Europe. There are no reports, however, regarding this relationship in Japanese medical education.Methods: We conducted a cross-sectional survey using a self-administered questionnaire to investigate formal undergraduate curricula on the relationship between physicians and the pharmaceutical industry.Results: Forty-four of 80 medical schools approved participation in the study, with 16 (36.0%) reporting having a formal curriculum on drug promotion. Many of the themes included in the programs were related to research ethics or conflict of interest in research, with drug promotion covered in only a few programs.Discussion: More discussion and investigation into undergraduate education on the relationship between physicians and the pharmaceutical industry, especially on drug promotion, is warranted.

  To examine the status of pharmaceutical industry support for junior residency education in Japan, we performed a questionnaire survey of 445 residency program directors （response rate, 76%）.
1） Fifty-one percent of respondents thought that industry support was necessary for education, and 28% did not believe that industry support negatively affects residents’ prescribing behaviors.
2） Twelve percent said their institutions had a curriculum for physician-industry relationships. Ten percent prohibit residents from meeting with pharmaceutical representatives, and 30% ban gifts from industry.
3） Fifty-one percent reported that they had pharmaceutical industry-sponsored in-hospital educational events for residents, and 73% reported that they had industry-sponsored in-hospital educational events which residents were allowed to attend.
4） Program directors’ belief that industry support was necessary for education predicted that programs would receive such support.
