An isolated huge unruptured aneurysm of the right coronary sinus of Valsalva was detected incidentally in a 47-year-old man. Echocardiography and aortograms revealed severe aortic insufficiency with moderate stenosis, and mild dilatation of the lower ascending aorta without annulo-aortic ectasia. At operation, a sclerotic bicuspid aortic valve was confirmed. These abnormal findings necessitated a reconstruction of the aortic root with a valved conduit and reimplantation of the coronary arteries (Bentall operation with the Carrel patch technique). Pathologic examination of the resected aortic wall showed diffuse sclerotic change and partial medial degeneration.

Primary cardiac tumors are comparatively rare. Primary cardiac angiosarcoma is the most common cardiac malignant tumor and the most common site of this tumor is in the right atrium. It is usually difficult to diagnose and treat this condition before death. The present case of primary cardiac angiosarcoma was located in the left atrium, which is very rare. A cardiac malignant tumor was suspected in this 56-year-old man based on chest MRI examination. The operation was performed successfully but its outcome was very poor.

Objective：The aim of this study was to examine the relationships between the timing of gait acquisition and the length of hospitalization, and to clarify the differences in background factors and functional recovery during the early postoperative period and their effect on the variability in gait acquisition.
Methods：We recruited 148 patients who underwent total knee arthroplasty (TKA) at three hospitals. The participants were divided into two groups on the basis of the number of days needed to achieve independent gait at ≤14 days after surgery (group A) and ＞14 days after surgery (group B). We compared the background factors between the two groups. Additionally, we compared the preoperative and postoperative function in each group.
Results：We observed a significant positive correlation between the number of days needed to achieve independent gait and the length of hospitalization. In group A, the significant background factors were younger age and higher preoperative activity level. In group A, compared with the level of preoperative function, the postoperative maximum knee extension angle on the operated side and pain had significantly improved. In both groups, the postoperative knee extensor strength on the operated side, knee extensor strength on the nonoperated side, knee flexion strength on the operated side, maximum knee flexion angle on the operated side, and walking speed were significantly reduced.
Conclusion：During early rehabilitation, it is necessary to consider the age and previous activities of patients. In addition, we suggest that early rehabilitation with a focus on reducing pain by alleviating inflammation and improving maximum knee extension angle on the operated side may be effective for fast acquisition of gait.

Objective：To elucidate factors associated with physical function and clarify the actual condition of functional deterioration in patients with knee osteoarthritis (OA) prior to total knee arthroplasty (TKA)．

Methods：We enrolled 467 patients with severe knee OA and preoperatively assessed the following parameters：background factors (sex, age, BMI, K-L grade, and pain) and physical function (muscle strength of knee extensors and flexors, and knee joint angles). A multiple regression analysis was performed to determine the relationship between the independent background factors and dependent physical functions. The median of preoperative function based on selected factors of physical function was calculated.

Results：Based on the multiple regression analysis, sex, BMI, K-L grade, and pain statistically significantly correlated with muscle strength of knee extensors and flexors. Sex and BMI statistically significantly correlated with knee joint flexion angle. K-L grade statistically significantly correlated with knee joint extension angle. The median of muscle strength for knee extension was 0.98/0.92 Nm/kg (Grade 3/Grade 4) for males and 0.70/0.59 Nm/kg for females. The median of muscle strength for knee flexion was 0.53/0.45 Nm/kg for males, 0.36/0.30 Nm/kg for females. The median for knee joint flexion angle was 130° for males and 120° for females. The median for knee joint extension angle was -5°/-10° (Grade 3/Grade 4)．

Conclusion：We clarified the degree of muscle strength and range of motion before TKA in patients with knee OA. We believe that the findings obtained in this study will contribute to explaining the functional deterioration of patients with knee OA.

OBJECTIVE: Interest in the "at-risk mental state" (ARMS) for psychosis has increased because early intervention is expected to delay or prevent the onset of schizophrenia. However, the optimum intervention strategy remains controversial, especially with regard to antipsychotics. Although administration of antipsychotic medications is often associated with adverse effects and raises ethical considerations, recent studies have shown that some novel antipsychotics are safer and more tolerable for young people than conventional antipsychotics. We investigated whether administration of perospirone, a combined serotonin (5-HT)/dopamine antagonist and 5-HT1A receptor agonist, could alleviate prodromal symptoms and be well tolerated by clinical high risk patients. METHODS: The participants were outpatients seeking help. The Structured Interview for Prodromal Symptoms was performed in patients identified as being at clinical high risk. The Scale of Prodromal Symptoms (SOPS) was also completed and changes of subjective experience were assessed with the Subjective Well-being under Neuroleptics, short version. The incidence of akathisia was recorded by using the Barnes Akathisia Scale. Subjects were monitored for 26 weeks after starting medication. RESULTS: SOPS scores improved significantly after 26 weeks of perospirone therapy, while BAS scores did not show deterioration. No serious adverse events occurred during the study. CONCLUSION: This trial suggests that perospirone therapy provides a clinical benefit for clinical high risk subjects without causing serious adverse events. Although further placebo-controlled studies are needed for confirmation, perospirone might be one of optimum treatments for individuals at imminent risk of psychosis.

We performed a preliminary study of the reliability of the lymphocyte stimulating test (LST) for Kampo medicine. LST for three kinds of Kampo medicines was performed in both a Kampo-administrated group and a non-administrated group. LST for each of the medicines was negative for seven of eight subjects in the non-administrated group, but was negative for four of 11 subjects in the Kampo-administrated group. The LST-positive participants had no allergic state, and some among them were negative in challenge test. This preliminary study suggests that LST for Kampo medicine is likely to be false-positive.

Continuous duodenal levodopa/carbidopa intestinal gel delivery by a gastrostomy infusion system improves control of Parkinson’s disease. The overall complication rates of percutaneous endoscopic gastrojejunostomy were reported to be 41% and 59% for immediate and delayed adverse events, respectively. A 72-year-old woman underwent percutaneous endoscopic gastrojejunostomy using the delivery system noted above. Abdominal pain and vomiting occurred 3 months later. Esophagogastroduodenoscopy showed a longitudinal ulcer extending from the lower gastric body to the ileum end, with small intestinal telescoping. Colonoscopy showed a large bezoar of food residue that was attached around the tip of the tube, reaching the ascending colon, which may have acted as an anchor. Thus, the gastric antrum and small intestine were shortened with telescoping. This complication was resolved by crushing the bezoar with forceps during colonoscopy and can be prevented by consuming a fiber-free diet and periodic exchanges of the tube using esophagogastroduodenoscopy.

Human epidemiological and animal studies have demonstrated that excess iron is a risk for cancer. The responsible mechanisms are: 1) increased intracellular iron catalyzes the Fenton reaction to generate hydroxyl radicals, leading to mutagenic oxidative DNA lesions; 2) iron is necessary for cellular proliferation as cofactors of many enzymes. Thus, iron-excess milieu promotes selecting cellular evolution to ferroptosis-resistance, a major basis for carcinogenesis. Ferritin is a 24-subunit nanocage protein required for iron storage under the regulation of the iron-regulatory protein (IRP)/iron-responsive element (IRE) system. Ferritin is a serum marker, representing total body iron storage. However, how ferritin is secreted extracellularly has been unelucidated. We recently discovered that an exosomal marker CD63 is regulated by the IRP/IRE system and that iron-loaded ferritin is secreted as extracellular vesicles under the guidance of nuclear receptor coactivator 4 (NCOA4). On the other hand, we found that macrophages under asbestos-induced ferroptosis emit ferroptosis-dependent extracellular vesicles (FedEVs), which are received by nearby mesothelial cells, resulting in significant mutagenic DNA damage. Therefore, cells, including macrophages, can share excess iron with other cells, via iron-loaded ferritin packaged in extracellular vesicles as safe non-catalytic iron. However, similar process, such as one involving FedEVs, may cause accumulation of excess iron in other specific cells, which may eventually promote carcinogenesis.

In the areas of home medical care and self-medication, the role of the pharmacist is growing, partly as a result of Japan’s aging society and the need to reduce medical costs. In response, the Kinki University Faculty of Pharmacy implemented a physical assessment practical training seminar in order to improve the physical assessment skills of practicing pharmacists. A series of questionnaires were conducted among pharmacists to investigate their perceptions of physical assessment practical training seminars. The results of the questionnaires were analyzed using Customer Satisfaction (CS) analysis and text mining. Based on a 5-point scale (1-low∼5-high), questionnaires revealed satisfaction for physical assessment practical training seminars was 4.6±0.6 (Ave.±S.D.). CS analysis revealed that the items “lectures” and “case seminars” had the highest level of satisfaction. However, items showing low levels of satisfaction were “auscultation of respiratory sounds” and “SBAR (Situation, Background, Assessment, Recommendation).” Results of text mining suggested a relationship between “physical assessment” and “difficult”. Analysis of the questionnaires showed a high level satisfaction with physical assessment practical training seminars, notably physical assessment practice methods. However, CS analysis and text mining indicate the finer techniques of physical assessment were difficult to acquire.

Objectives: Ceramic bathing is a kind of sauna on which visitors lie and enjoy hot stimulus. Our aim in this study was to examine whether an intensive exposure of ceramic bathing improves physical and psychological functions or not. Methods: The study design is a non-randomized single-arm before-after trial. The 38 subjects (6 males and 32 females) were enrolled in Yachiyo city, Chiba, Japan and bathing 8 times in 2 months from November 2009 to May 2010. Physiological, physical and psychological functions were examined when participants were bathing first and last time. We measured systolic blood pressure, diastolic blood pressure, pulse rate and body mass index (BMI) as physiological functions and SF-8, Profile of Mood States (POMS), and Cornell Medical Index (CMI) questionnaire score for examining subjective changes of physical and psychological functions. The results were compared by paired t test. Results: Physiological functions were not changed considerably by intensive bathing, excepting a slight decline of diastolic blood pressure. Concerning subjective physical functions, we observed statistically-significant improvement in 11 items: eyes/ears, cardiovascular, digestive, skin, nervous, physical component summary, general health, role physical, bodily pain, vitality, and physical functioning. Regarding subjective psychological functions, 9 items were significantly improved: sensitivity, anger, psychological component summary, role emotional, mental health, tension-anxiety, anger-hostility, fatigue, and confusion. We observed certain but not-significant improvements in 6 items of subjective physical functions (respiratory, musculo-skeletal, genito-urinary, fatigability, frequency of illness, and social functioning) and 5 items of subjective psychological functions (depression in CMI and POMS, maladaptation, anxiety, and tension). There observed little change in only 1 item in subjective psychological function (vigor in POMS). There were no items showing significant deterioration after intensive bathing. Conclusion: An intensive exposure of ceramic bathing might be effective in improving physical and psychological functions without changing physiological status.
