A 58-year-old man was admitted for pneumonia after several business trips to Thailand, Vietnam, and Malaysia. Despite resolution of pneumonia on chest X-ray, high fever persisted. CT scan revealed a juxtarenal, atypical-shaped abdominal aortic aneurysm of 4.5cm in size, and this was thought to be the cause of persisting fever. After prolonged antibiotic treatment, surgical resection and prosthetic tube replacement of the aneurysm was performed. The aneurysm was a pseudoaneurysm, and histological examination showed chronic inflammation with no atherosclerotic change. It was thought to be of mycotic origin. On the 12th day after operation, he became febrile, and an arterial blood culture yielded Burkholderia pseudomallei. Antibiotics chosen according to sensitivity tests, were given. He was finally discharged with no exidence of persisting infection, on the 55th day after operation.

Purpose: We examined the safety and efficacy of cataract surgery and postoperative management in our hospital and at the homes of the patients who live on medically underserved remote.
Patients and methods: A total of 27 patients (54 eyes), who were followed in our hospital or at their homes were enrolled in this study. Cataract surgery was performed on them between January 2009 and January 2010 and we could follow up six months postoperatively. We divided these patients into two groups:group I (GI) consisted of 13 patients who could come to our hospital regularly during both preoperative and postoperative periods, and group II (GII) consisted of 14 patients who could not come to our hospital regularly during either preoperative or postoperative periods. Cataract surgeries were performed on all the patients in GI and GII in our hospital. The patients in GI were hospitalized for three days and those in GII were for seven days. After cataract surgery, the patients in GI had their eyes checked regularly in our hospital and those in GII were in their homes where the doctor visited. Postoperative ophthalmic clinical tests were conducted to examine visual acuity, intraocular pressure and fundus.
Results: GI comprised three males and 10 females. Their age averaged 79.3. GII comprised four males and 10 females. Their age averaged 82.6. Preoperative ophthalmic examinations found that preoperative average visual acuity (LogMAR and decimal visual acuity in parentheses) and spherical equivalent in GI and GII were 0.69 (0.41), 0.80 (0.33) and -0.43 dioptors, -0.42 dioptors respectively, showing no significant differences between the two groups. Postoperative ophthalmic examinations found that, best corrected visual acuity (LogMAR) was significantly increased to 0.36 (0.66) and 0.44 (0.53) in GI and GII respectively, showing no significant differences either.
Conclusions: We concluded that we could get safe and efficient cataract surgery and postoperative management combined with prolonged hospitalization and house calls on the patients who live in the isolated islands.

The core curriculum of the pharmacy education model was revised in 2013 based on the “Basic competencies required of a pharmacist” that should be developed by graduation. Specific behavioral objectives to acquire include competency in “The ability to implement pharmacotherapeutic management”, which involves gaining the ability to understand patient information, prescription design and proposal, as well as pharmacotherapeutic assessment. In order to improve this ability, it is necessary for students to acquire basic knowledge about pathology, pharmacology, and pharmacotherapy and to integrate and apply this knowledge to patients in practice. We introduced an integrated program called “Integrated Clinical Pharmacy” for fifth-year students at Hokkaido Pharmaceutical University. In this program, students take an objective test on the basic knowledge of pathology, pharmacology, and pharmacotherapy and learn how to design pharmaceutical care plans using individual patient cases. A self-evaluation questionnaire survey about the ability to develop care plan was conducted on students who completed the program. Based on the objective test and self-evaluation questionnaire results, we studied whether basic knowledge was fully established and whether the ability to utilize this knowledge was acquired through this program. We found that although the ability to select an individual component of care plan did improve, this ability wasn’t correlated with the degree of basic knowledge, and performance in summarizing care plan did not improve. These results suggested that it is necessary to understand the connection between components of the care plan and strategies to focus on improving the ability to integrate basic knowledge.

OBJECTIVE: We evaluated the effect of various patient characteristics and time-density curve (TDC)-factors on the test bolus-affected vessel enhancement on coronary computed tomography angiography (CCTA). We also assessed the value of generalized linear regression models (GLMs) for predicting enhancement on CCTA. MATERIALS AND METHODS: We performed univariate and multivariate regression analysis to evaluate the effect of patient characteristics and to compare contrast enhancement per gram of iodine on test bolus (ΔHUTEST) and CCTA (ΔHUCCTA). We developed GLMs to predict ΔHUCCTA. GLMs including independent variables were validated with 6-fold cross-validation using the correlation coefficient and Bland–Altman analysis. RESULTS: In multivariate analysis, only total body weight (TBW) and ΔHUTEST maintained their independent predictive value (p < 0.001). In validation analysis, the highest correlation coefficient between ΔHUCCTA and the prediction values was seen in the GLM (r = 0.75), followed by TDC (r = 0.69) and TBW (r = 0.62). The lowest Bland–Altman limit of agreement was observed with GLM-3 (mean difference, −0.0 ± 5.1 Hounsfield units/grams of iodine [HU/gI]; 95% confidence interval [CI], −10.1, 10.1), followed by ΔHUCCTA (−0.0 ± 5.9 HU/gI; 95% CI, −11.9, 11.9) and TBW (1.1 ± 6.2 HU/gI; 95% CI, −11.2, 13.4). CONCLUSION: We demonstrated that the patient's TBW and ΔHUTEST significantly affected contrast enhancement on CCTA images and that the combined use of clinical information and test bolus results is useful for predicting aortic enhancement.

OBJECTIVE: To evaluate the effect of patient characteristics on popliteal aortic contrast enhancement at lower extremity CT angiography (LE-CTA) scanning. MATERIALS AND METHODS: Prior informed consent to participate was obtained from all 158 patients. All were examined using a routine protocol; the scanning parameters were tube voltage 100 kVp, tube current 100 mA to 770 mA (noise index 12), 0.5-second rotation, 1.25-mm detector row width, 0.516 beam pitch, and 41.2-mm table movement, and the contrast material was 85.0 mL. Cardiac output (CO) was measured with a portable electrical velocimeter within 5 minutes of starting the CT scan. To evaluate the effects of age, sex, body size, CO, and scan delay on the CT number of popliteal artery, the researchers used multivariate regression analysis. RESULTS: A significant positive correlation was seen between the CT number of the popliteal artery and the patient age (r = 0.39, p < 0.01). A significant inverse correlation was observed between the CT number of the popliteal artery and the height (r = −0.48), total body weight (r = −0.52), body mass index (r = −0.33), body surface area (BSA) (r = −0.56), lean body weight (r = −0.56), and CO (r = −0.35) (p < 0.001 for all). There was no significant correlation between the enhancement and the scan delay (r = 0.06, p = 0.47). The BSA, CO, and age had significant effects on the CT number (standardized regression: BSA −0.42, CO −0.22, age 0.15; p < 0.05, respectively). CONCLUSION: The BSA, CO, and age are significantly correlated with the CT number of the popliteal artery on LE-CTA.

STUDY DESIGN: Controlled laboratory study. PURPOSE: This study aimed to evaluate the efficacy of platelet-rich plasma (PRP) stored at room temperature (RT), frozen, or after freeze-drying. OVERVIEW OF LITERATURE: PRP enriches tissue repair and regeneration, and is a novel treatment option for musculoskeletal pathologies. However, whether biological activity is preserved during PRP storage remains uncertain. METHODS: PRP was prepared from blood of 12 healthy human volunteers (200 mL/person) and stored using three methods: PRP was stored at RT with shaking, PRP was frozen and stored at −80℃, or PRP was freeze-dried and stored at RT. Platelet counts and growth factor content were examined immediately after preparation, as well as 2, 4, and 8 weeks after storage. Platelet activation rate was quantified by flow cytometry. RESULTS: Platelet counts were impossible to determine in many RT samples after 2 weeks, but they remained at constant levels in frozen and freeze-dried samples, even after 8 weeks of storage. Flow cytometry showed approximately 80% activation of the platelets regardless of storage conditions. Almost no growth factors were detected in the RT samples after 8 weeks, while low but significant expression was detected in the frozen and freeze-dried PRP. Over time, the mean relative concentrations of various growth factors decreased significantly or disappeared in the RT group. In the frozen group, levels were maintained for 4 weeks, but decreased significantly by 8 weeks (p <0.05). The freeze-dried group maintained baseline levels of growth factors for the entire 8-week duration. CONCLUSIONS: Freeze-drying enables PRP storage while maintaining bioactivity and efficacy for extended periods.

PURPOSE: It has been reported that the Pulse Contour Cardiac Output (PiCCO) is very useful mainly in the field of intensive care and treatment to grasp the pathophysiological conditions of pulmonary edema because of its capability of obtaining data such as Pulmonary Vascular Permeability Index (PVPI) and Extra Vascular Lung Water (EVLW). Furthermore, a high degree of usability of various markers has been reported for better understanding of the pathological conditions in cases with septicemia. MATERIALS AND METHODS: The correlation between the cardiorespiratory status based upon the PiCCO monitor (EVLW and PVPI) and inflammatory markers including C reactive protein, procalcitonin (PC), and Endotoxin Activity Assay (EAA) were evaluated in 11 severe cases that required treatment with a respirator in an intensive care unit. RESULTS: The EAA values were significantly higher in patients with abnormal EVLW at 0.46+/-0.20 compared to the normal EVLW group at 0.21+/-0.19 (p=0.0064). In a similar fashion, patients with abnormal PVPI values tended to have higher PC levels at 18.9+/-21.8 compared to normal PVPI cases at 2.4+/-2.2 (p=0.0676). On the other hand, PVPI was significantly higher in the abnormal EAA group at 3.55+/-0.48 in comparison with the normal EAA group at 1.99+/-0.68 (p=0.0029). The abnormal EAA group tended to have higher PVPI values than the normal EAA group. CONCLUSION: The EAA is a measurement method designed to estimate the activity of endotoxins in the whole blood. Our results suggest that the EAA value, which had the greatest correlation with lung disorders diagnosed by the PiCCO monitoring, reflects inflammatory reactions predominantly in the lungs.
