A 77-year-old woman underwent percutaneous coronary intervention (PCI) for chronic total occlusion of the left anterior descending artery using a drug-eluting stent (DES). Re-stenosis, stent fracture, and aneurysm were found on follow-up coronary angiography (CAG), and thus implantation of multiple DESs was required. Surgery was indicated because CAG 48 months after first DES implantation revealed enlargement of the aneurysm with other new lesions. She successfully underwent off-pump coronary artery bypass grafting and resection of the aneurysm.

A 62-year-old woman was referred to our hospital for treatment of hemolytic anemia 10 years after total arch replacement for acute aortic dissection. The cause of hemolysis was confirmed to be mechanical damage of red blood cells at the kinked graft. Because aortic valve regurgitation and occlusion of the left subclavian artery were also found, resection of the kinked graft, aortic valve replacement and reconstruction of the left subclavian artery were carried out concomitantly at reoperation. Her postoperative course was uneventful, and hemolysis resolved soon after the operation.

Infectious abdominal aortic aneurysm is a relatively rare disease, and there is no consensus regarding its surgical treatment. Medical infectious control should be concerned comparison with surgical treatment if there is sepsis, however we sometimes have no other choice but emergency operation for uncontrollable cases. In many reports, cryopreserved homografts were used as in-situ alternative grafts for infectious aortic aneurysms because they had some merits such as anti-infectious effects, suitability and so on. However the number of in-situ cryopreserved homograft replacement cases are few, and the long term result is unclear. We encountered a ruptured cropreserved homograft case 7 months after urgent in-situ cryopreserved homograft replacement. We report the case and refer to the relevans literature.

Prompt and accurate diagnosis of malarial patients is a crucial factor in controlling the morbidity and mortality of the disease. Effective treatment decisions require a correct diagnosis among mixed-species malarial patients. Differential diagnosis is particularly important in cases of Plasmodium vivax, a species that shares endemicity with P. falciparum in most endemic areas. Moreover, it is difficult to identify P. knowlesi on the basis of morphology alone, and rapid diagnostic tests are still not available for this malaria species. Therefore, the development of diagnostic tests applicable to the field is urgently needed. 1-Cys peroxiredoxin (1-Cys-Prx) in P. falciparum is abundantly expressed in the mature asexual stages, making it a promising candidate as a diagnostic antigen. In this study, we produced five monoclonal antibodies (mAbs) against P. falciparum 1-Cys-Prx (Pf1-Cys-Prx) by immunizing BALB/c mice with recombinant Pf1-Cys-Prx and subsequent hybridoma production. Cross reactivity of established mAbs with the orthologous molecule of Pf1-Cys-Prx in P. vivax (Pv1-Cys-Prx) and P. knowlesi (Pk1-Cys-Prx) was examined. Western blot analyses showed that three mAbs reacted with Pv1-Cys-Prx and Pk1-Cys-Prx but two mAbs did not. These results indicate that the two mAbs were effective in differentiating P. falciparum from P. vivax and P. knowlesi and could be used in differential diagnosis as well as comparative molecular studies of human Plasmodium species.

This retrospective case series enrolled 13 patients who underwent posterior fixation with both transdiscal screws for diffuse idiopathic skeletal hyperostosis (TSDs) and pedicle screws (PSs) to treat spinal injury accompanied by diffuse idiopathic skeletal hyperostosis (DISH). To describe the usefulness, feasibility, and biomechanics of TSD. Vertebral bodies accompanied by DISH generally have lower bone mineral density than normal vertebral bodies because of the stress shielding effect. This phenomenon tends to makes screw fixation challenging. To our knowledge, solutions for this issue have not previously been reported. Patients were assessed using the data on surgical time, estimated intraoperative blood loss, mean number of stabilized intervertebral segments, number of screws used, perioperative complications, union rate, and the three-level EuroQol five-dimensional questionnaire (EQ5D-3L) score at the final follow-up. The Hounsfield unit (HU) values of the screw trajectory area, and the actual intraoperative screw insertion torque of TSDs and PSs were also analyzed and compared. The surgical time and estimated intraoperative blood loss were 165.9±45.5 minutes and 71.0±53.4 mL, respectively. The mean number of stabilized intervertebral segments was 4.6±1.0. The number of screws used was 4.9±1.3 for TSDs and 3.0±1.4 for PSs. One death occurred after surgery. The union rate and EQ5D-3L scores were 100% and 0.608±0.128, respectively. The HU value and actual intraoperative screw insertion torque of TSDs were significantly better than those of PSs ( We were able to achieve stable surgical outcomes using the combination of TSDs and PSs. The HU value and actual intraoperative screw insertion torque were significantly higher for TSDs than for PSs. Based on these results, when treating thoracolumbar spinal fractures accompanied by DISH in elderly populations, the TSD could be a stronger anchor than the PS.

The purpose of this study is to evaluate the efficacy of hochuekkito for late-onset hypogonadism (LOH) patients. We administered hochuekkito 7.5 g/day for 8 weeks to 47 patients with LOH whose AMS scale was more than 27. We assessed the patients' symptom change with the AMS, SHIM, SDS, BDI, and SF-36. We measured their endocrine profiles and levels of their cytokines. At the end of study, 31 of 47 patients were evaluable. No significant difference in subjective symptoms was seen with any questionnaire after 8 weeks hochuekkito administration. However, hochuekkito significantly increased free testosterone and decreased ACTH/cortisol levels. Thus we believe hochuekkito is beneficial for the treatment of LOH.

Saffron (Crocus sativus L.) is classified as a beneficial herb in the treatment of “Oketsu,” eliminating blood stagnation. The clinical symptoms of “Oketsu” include feeling cold and arthralgia. The pathological condition of “Oketsu” is considered to be increased blood viscosity and microvascular disorders.However, no useful biomarker has been reported for evaluation of the degree of “Oketsu.” Here, we investigated the clinical effect of saffron on the symptoms of “Oketsu” in patients with autoimmune diseases. At the same time, we measured the plasma levels of platelet factor 4 (PF-4) and beta-thromboglobulin (β-TG) as platelet activation markers. Seventy-one patients (66 women and 5 men, mean age 52.3 ± 16.1) were studied. They were administered saffron (300mg∼900mg) with traditional Kampo medicine. The clinical symptoms of “Oketsu” improved (80.9%, n=38/47) and we measured PF-4 and β-TG in pre-and post-saffron treatment periods. The plasma levels of PF-4 and β-TG significantly decreased after saffron therapy (PF-4 : before 49.6 ± 29.8, after 24.0 ± 19.6ng/ml, β-TG : before 117.5 ± 64.0, after 64.6 ± 47.1ng/ml;paired t-test, p < 0.0001, respectively). These results suggest that saffron is effective in treatment of the symptoms of “Oketsu” in allergy and collagen disease patients. Moreover, PF-4 and β-TG may be useful biomarkers of the degree of “Oketsu.”

Many patients with mental disorders visit emergency departments (EDs). However, the majority of these patients do not receive psychiatric assessment. In the present study, we investigated the detailed proportion of patients with mental disorders visiting an urban ED in the largest northern city in Japan. A retrospective chart review study was performed at a University Hospital from January 2012 to December 2015. The reasons for psychiatric consultations made by ED staff, and the primary psychiatric diagnoses were investigated. Among all living patients, 20% of them received consultations. The most common reason for consultation was suicide attempt followed by agitation or insomnia. Of all diagnoses, organic mental disorder was the most frequent and the mean age was significantly higher than the other diagnostic groups. Our study indicated that the frequency of psychiatric consultation was high. This indicates the high demand for mental health services at the ED. A thorough psychiatric assessment can provide adequate psychiatric services to acute patients; thereby possibly preventing suicide attempters from later actually dying by suicide.

PURPOSE: The purpose of this study was to investigate the clinical and hormonal features of patients with incidentally discovered adrenal adenomas in relation to corticotropin releasing hormone (CRH) testing and the clinical outcome of adrenalectomy. MATERIALS AND METHODS: Twenty-three consecutive patients with incidentally detected adrenal adenomas were included in this retrospective study. All the patients underwent abdominal computed tomography scans and hormonal assays, including assessment of circadian rhythms of plasma cortisol and corticotropin (adrenocorticotropic hormone, ACTH), a corticotropin stimulation test, and low-dose and high-dose dexamethasone tests. The patients were reevaluated at regular intervals (6, 12, and 24 months) for a median period of 24 months. Subclinical Cushing's syndrome (SCS) was diagnosed in patients with subtle hypercortisolism who did not present clinical signs of Cushing's syndrome. RESULTS: We calculated the responsive index (peak value of ACTH in CRH test/baseline value of ACTH in CRH test). Of 23 patients, 6 had Cushing's syndrome, 8 had SCS, and 9 had a non-functioning tumor. All patients underwent laparoscopic adrenalectomy. Several patients (5 of 6 with Cushing's syndrome and 2 of 8 with SCS) required cortisol replacement therapy after surgery. The remaining patients required no hormonal replacement after surgery. Those who required hormone replacement had a responsive index of less than 1.2. Those who did not need hormone replacement therapy had a responsive index of more than 2.0. CONCLUSIONS: In our limited experience, the responsive index of the CRH test might be a valuable tool for predicting the need for cortisol replacement after surgery in patients with SCS.
