Occupational health was taught to 3rd-year medical students using simulated patients and role playing. Patient profiles were created to enable students to consider psychosocial aspects, such as work environment and lifestyles, involved in occupational health. Simulated patients were used, later, students acted as patients and each student played the role of an occupational health doctor. The aim of the exercise was for students, through their own actions and observations, to learn communication skills and approaches to occupational health, such as prevention, health promotion, and the importance of health education, which are based on a biopsychosocial model.
Students were extremely interested and found the course valuable. This result shows the effectiveness and current shortage of active learning methods as well as the need for acquiring communication skills.
Although learning communication skills is most relevant to clinical medicine, active learning and communication training is also important for occupational health education because the latter should be based not on the traditional doctor-patient relationship but on the biopsychosocial model.

From 1995 till 1998, 21 cases of Stanford type A dissecting aortic aneurysm with a closed false lumen of the ascending aorta were treated in our institute. The patients were medically treated if the diameter of their ascending aorta stayed less than 50mm without recurrent dissection. Patients were categorized into three groups: Groups I, II and IIIR (retrograde dissection), according to the location of the entry analyzed by means of CT, angiography and operative findings. Seven cases of intramural hematoma (IMH) were included in this study. One case in Group II died of rupture and one case in Group IIIR died of multiple embolism caused by atrial fibrillation in the acute phase. One case in Group II died of stroke and one case in Group I died after surgery in the chronic phase. Four cases in Group I and II underwent surgery in the acute phase and five cases in Group I and II underwent surgery in the chronic phase, but only one case of Group IIIR required surgery. Six cases of IMH required surgery. The rates of freedom from operation at four years was 25%, 21% and 83% respectively (p=0.07). Essentially, Stanford type A dissection should be treated surgically even though the false lumen is thrombosed. However, in the case of retrograde dissection accompanied by an entry in the descending aorta, medical treatment may be a strategy option.

OBJECTIVE: To evaluate the efficacy and toxicity of paclitaxel plus carboplatin (TC)-based concurrent chemoradiotherapy (CCRT) followed by consolidation chemotherapy in the International Federation of Gynecology and Obstetrics (FIGO) stage IIIB/IVA cervical cancer patients. METHODS: We reviewed the medical records of FIGO stage IIIB/IVA cervical cancer patients (n=30) who had been intended to be treated with TC-based CCRT followed by consolidation chemotherapy (TC-CCRT-group) from April 2012–May 2016. Patients who had been treated with CCRT involving a single platinum agent (CCRT-group; n=52) or definitive radiotherapy alone (RT-group; n=74) from January 1997–September 2012 were also identified and used as historical controls. Survival was calculated using the Kaplan-Meier method and compared using the log-rank test. RESULTS: Of the 30 patients included in the TC-CCRT-group, 22 patients (73.3%) completed the planned TC-based CCRT. The most frequently observed acute grade 3/4 hematological toxicities were leukopenia and neutropenia, and diarrhea was the most common acute grade 3/4 non-hematological toxicity. After a median follow-up of 35 months, 9 patients (30.0%) had developed recurrent disease. The patients' estimated 3-year progression-free survival (PFS) and overall survival (OS) rates were 67.9% and 90.8%, respectively. In comparisons with historical control groups, the survival outcomes of TC-CCRT-group was significantly superior to CCRT-group in terms of OS (p=0.011) and significantly superior to RT-group in terms of both PFS (p=0.009) and OS (p<0.001). CONCLUSION: TC-based CCRT followed by consolidation chemotherapy is safe and effective. A randomized controlled study needs to be conducted to further evaluate the efficacy of this multimodal approach in this patient population.

Sixteen cases of malignant soft tissue sarcoma (STS; 10 canines and six felines) were treated with a novel triple therapy that combined photodynamic therapy, hyperthermia using indocyanine green with a broadband light source, and local chemotherapy after surgical tumor resection. This triple therapy was called photodynamic hyperthermal chemotherapy (PHCT). In all cases, the surgical margin was insufficient. In one feline case, PHCT was performed without surgical resection. PHCT was performed over an interval of 1 to 2 weeks and was repeated three to 21 times. No severe side effects, including severe skin burns, necrosis, or skin suture rupture, were observed in any of the animals. No disease recurrence was observed in seven out of 10 (70.0%) dogs and three out of six (50.0%) cats over the follow-up periods ranging from 238 to 1901 days. These results suggest that PHCT decreases the risk of STS recurrence. PHCT should therefore be considered an adjuvant therapy for treating companion animals with STS in veterinary medicine.

AIMTo analyze the relationship between sperm mitochondrial membrane potential and sperm motility parameters by means of a computer-assisted sperm analyzer (CASA) and in-vitro fertilization rate(%FR).

METHODSSemen samples were obtained from 26 men undergoing in vitro fertilization-embryo transfer (IVF-ET). Informed consent was obtained from all men prior to the study. Samples were prepared using wash and swim-up method in HEPES-HTF medium. The sperm motility (%MOT), progressive motility (%PMOT), average path velocity (VAP) microm/s), straight line velocity (VSL) (micro m/s), curvilinear velocity (VCL) (microm/s) and %hyperactivated sperm (%HA), and the %FR were assessed. The samples were incubated in the presence of 2.0 mciromol/L of 5,5',6,6'-tetra-chloro-1,1',3,3'-tetraethylbenzimidazolyl-carbocyanine iodide (JC-1) for 30 min at 37 degrees C in air and washed in PBS before flow cytometry (FACSCalibur: Becton Dickinson) analysis. The mitochondrial probe JC-1 was used to identify the mitochondrial membrane potential. The sperm was divided into three populations according to the fluorescence pattern as follows: the high mitochondrial membrane potential group (n=8), the moderate group (n=5), and the low group (n=13). Statistical analysis was performed using unpaired t-test.

RESULTSSignificant differences were found between the high and the low groups in %MOT (91.1+/-8.5 vs 63.0+/-32.7, mean+/-SD), VAP (73.0+/-14.2 vs 52.1+/-12.5), VCL (127.0+/-28.1 vs 87.0+/-22.6), %HA (27.3+/-23.6 vs 7.2+/-9.0) and %FR [73.2 (48/56) vs 59.0 (69/117)]. No significant differences were found in other CASA parameters.

CONCLUSIONWhen the sperm mitochondrial membrane potential increases, sperm motility parameters and fertility potential will also increase. The JC-1 dye method is useful to predict sperm fertility potential.

We report a case of 2X-year-old man with G4 chronic kidney disease (CKD G4). He had a decline in estimated glomerular filtration rate (eGFR) after the initiation of BEP (cisplatin, etoposide, bleomycin) therapy followed by VelP (ifosfamide, cisplatin, vinblastine) therapy for mixed germ cell testicular tumor. The patient’s eGFR did not recover during 59 months after chemotherapy, but showed a tendency to improve after treatment with yojinkodakuto. Yojinkodakuto was prepared by the IPCD (immersing powdered crude drugs) method. The IPCD method was adopted to ensure convenience and good quality prescription herbal medicines. Although eGFR fluctuated after yojinkodakuto treatment, at 3 years, serum creatinine (sCr) and eGFR progressed well, with sCr reducing from 3.98 mg/dL at initiation to 2.6 mg/dL and eGFR increasing from 16 mL/min/1.73 m2 to 25.4 mL/min/1.73 m2. In addition, a long-term eGFR plot analysis confirmed the 3-year improvement trend.
