We reported a rare case of aorto-left ventricular fistula with the unruptured aneurysm of the Valsalva sinus due to the infective endocarditis. Preoperatively trans-echocardiographic examination revealed the ruptured left sinus of Valsalva aneurysm protruded toward the left ventricule. Aorto-left ventricular fistula contiguous to the unruptured aneurysm of the right valsalva sinus, however, was detected at operation. Granulation tissue resembling healed infective vegetation was detected in the margin among the orifices of this fistula and Valsalva aneurysm. Pathological examination showed excessive accumulation of white blood cells, which suggested infective endocarditis.

We have conducted driving fitness evaluations for post-illness patients in our clinic since 2008. Many patients expressed a desire to resume driving; thus, primary care physicians and rehabilitation staff collaborated to establish an evaluation system. We conducted cognitive dysfunction evaluation, driving simulator evaluation, and evaluation at driving schools. Among 160 patients, we evaluated 87 to be fit to drive, and eight to be unfit. We describe the significance and challenges of assessing patients' driving aptitude in primary care.

[Purpose] We introduced subcutaneous suture with a synthetic absorption thread and examined its efficacy on surgical site infection after pancreaticduodenectomy (PD). [Method] In hour hospitals, PD was performed in a total of 69 cases from March 2006 through March 2014. They was divided into two groups-one consisting of 31 cases in which the skin wounds with staplers (non-subcutaneous suture group), and the other consisting of 38 cases in which surgical wounds were closed with subcutaneous sutures (subcutaneous suture group), and the incidence of surgical site infection (SSI) were compared between the two groups. [Result] Incidence of surface SSI occurred in eight cases (21.0%) in the non- subcutaneous suture group and three cases (9.7%) in the subcutaneous suture group (p=0.17). The incidence of SSI was decreased in the subcutaneous suture group than in the non-subcutaneous suture group, but no statistically significant difference was observed between the two groups. However, taking into account the advantages such as the reduction of patient’s medical expenses, and the burden of ward duties, further examination with an additional number of patients was thought to be necessary.

The aim of this study was to demonstrate a time-series relationship in drop jump (DJ) from a pre-set state with improved performance. Twelve male college athletes performed a DJ from a height of 0.60 m. DJ performance was assessed with a DJ-index (jump height/contact time). Short-interval intracortical inhibition (SICI) was assessed as intracortical inhibitory circuit excitability in a pre-set state, calculated by using paired-pulse transcranial magnetic stimulation for the medial gastrocnemius muscle (MG). The H-reflex of the left MG and the ankle joint torque were calculated in the early phase of take-off. A significant correlation was shown between ⊿SICI during the pre-set state and the DJ index. Thus, we examined the relationships between phases, focusing on time-series relationships throughout the jump period. The results showed a significant correlation between ⊿SICI during the pre-set state and %H-reflex during the early phase of take-off, and peak ankle joint torque during take-off was also significantly correlated with %H-reflex during the early phase of take-off. A significant correlation was also demonstrated between ankle joint torque during take-off and the DJ-index. In conclusion, we observed a time-series relationship between DJ from a pre-set state and improved performance. A decrease of intracortical inhibitory circuit excitability in the pre-set state affects stretch-reflex facilitation during the early phase of take-off; stretch-reflex facilitation results in the development of a large force in the ankle joint during take-off, and this force develops ankle joint torque. These findings may be used to improve jump performance.

PREAVOID is pharmaceutical intervention that is utilized to illustrate pharmacists’ contributions to medical care. Currently, there is a great need for pharmacists to provide good medical services to inpatients; as a result, many pharmacists conduct pharmaceutical management in hospital wards. However, pharmacists who have limited experience in working in the ward do not know exactly what they should check with respect to pharmaceutical management. To resolve this problem, we determined 16 pharmaceutical-management items based on PREAVOID that was conducted at Nagara Medical Center. Moreover, we conducted a pre-questionnaire survey assessing whether pharmacists who had worked in the ward for fewer than 4 years attended to these 16 check items in their daily work prior to our introducing the list to them. The results indicated that pharmacists who had fewer than 2 years of experience working in wards attended to the 16 check items less than those who had more than 2 years of experience, and approximately half of the pharmacists had not received adequate guidance before beginning work at the ward. In addition, most pharmacists indicated that clear check points were useful for conducting pharmaceutical management and the 16 check items were useful for their daily work. These results indicate that the 16 check items are a useful educational tool for enabling pharmacists to conduct high quality pharmaceutical management from the initial stage and that using the 16 check items is superior to pharmacists only gaining this ability via prolonged experience working in the ward.

Objective:
To assess the relationships between phase angle and muscle mass, strength, and physical function in patients with heart failure.
Methods:
This study used a cross-sectional design. The analysis included 51 patients with heart failure. The Short Physical Performance Battery, one-leg standing time, handgrip strength, phase angle, and skeletal muscle index were measured. To identify explanatory variables of phase angle, hierarchical multiple regression analysis was performed.
Results:
Handgrip strength was found to be an explanatory variable of phase angle independent of age, sex, and body mass index. This model was able to explain 30.4% of the model variance for phase angle.
Conclusion
In patients with heart failure, improving muscle strength rather than muscle mass or physical function might be more important for improving phase angle. Handgrip strength is an important outcome for improving prognosis in patients with heart failure.

To educate medical professionals to meet the needs of future medical care, which will be highly complex and require a broader perspective, it is not enough to provide education that emphasizes positivism based on natural scientific thinking, such as clinical reasoning. It is also important to provide education based on a phenomenological perspective that seeks to understand patients’ experiences in the living world and their meaning, as seen in biopsychosocial models. We have developed an online class on clinical reasoning for fourth-year medical students prior to clinical practice, in which students can simultaneously learn clinical reasoning and biopsychosocial models through structured case studies. We expect that this teaching model will be widely adopted, as it allows students to learn both positivist and phenomenological perspectives, and to view patients as individuals in their daily lives, through a multifaceted learning experience using the same case study.

Purpose:
The study aimed to compare the diagnostic performance of washout-parametric imaging (WOPI) with that of conventional contrast-enhanced ultrasound (cCEUS) in differentiating focal liver lesions (FLLs).
Methods:
A total of 181 FLLs were imaged with contrast-enhanced ultrasound using Sonazoid, and the recordings were captured for 10 minutes in a prospective setting. WOPI was constructed from three images, depicting the arterial phase (peak enhancement), the early portal venous phase (1-minute post-injection), and the vasculo-Kupffer phase (5 or 10 minutes post-injection). The intensity variations in these images were color-coded and superimposed to produce a single image representing the washout timing across the lesions. From the 181 FLLs, 30 hepatocellular carcinomas (HCCs), 30 non-HCC malignancies, and 30 benign lesions were randomly selected for an observer study. Both techniques (cCEUS and WOPI) were evaluated by four off-site readers. They classified each lesion as benign or malignant using a continuous rating scale, with the endpoints representing "definitely benign" and "definitely malignant." The diagnostic performance of cCEUS and WOPI was compared using the area under the receiver operating characteristic curve (AUC) with the DeLong test. Interobserver agreement was assessed using the intraclass correlation coefficient (ICC).
Results:
The difference in average AUC values between WOPI and cCEUS was 0.0062 (95% confidence interval, -0.0161 to 0.0285), indicating no significant difference between techniques. The interobserver agreement was higher for WOPI (ICC, 0.77) than cCEUS (ICC, 0.67).
Conclusion
The diagnostic performance of WOPI is comparable to that of cCEUS in differentiating FLLs, with superior interobserver agreement.
