Background: Lumpectomy is a standard surgery for breast cancer; however, it results in breast deformity, especially after radiation therapy. Wider surgical margin correlates lower local recurrence rate. However, bigger defect brings worse cosmetic outcome. The use of a simple filler for the defect is expected. We aimed to improve the cosmetic outcome by using an absorbable Vicryl mesh for breast reconstruction immediately post-lumpectomy. Methods: One sheet of Vicryl woven mesh was prepared for insertion, washed the cavity with natural saline, and placed into the space. The cosmetic outcome was scored for the size, shape, scar, and softness of the breast. The size, shape, color, and position of the nipple-areola complex were also scored. Adverse events were collected retrospectively. Results: From April 2008 to October 2014, 24 female patients received immediate Vicryl mesh insertion. A lumpectomy only group was recruited for cosmetic analysis. All patients received postsurgical radiotherapy. The mean cosmetic assessment score was 8.0 and 9.1 of 12 for the Vicryl mesh group and lumpectomy only group, respectively (P = 0.17). Sixteen patients had adverse events such as erythema at approximately 2 weeks post-surgery. No significant differences were shown except adverse events between two groups. No patient has had local recurrence thus far. Conclusion: Immediate Vicryl mesh insertion leads to significantly increased incidence of postoperative complications and delay in commencement of adjuvant radiotherapy. Furthermore, the cosmetic outcomes are not superior to that of no reconstruction. The development of superior biomaterials is anticipated for breast reconstruction after lumpectomy. © 2017.

Background: Taking an advantage of the high sensitivity of 3D T2*-weighted gradient-recalled-echo (GRE) imaging to cerebral microbleeds, we investigated the relationship between cerebral microbleeds and leukoaraiosis. Methods: Participants aged 40years or more have been evaluated for the presence of cerebral microbleeds using 3D T2*-GRE sequence since 2006. The severity of periventricular hyperintensity (PVH) and deep white matter hyperintensity (DWMH) on fluid attenuated inversion recovery images was assessed using Fazekas rating scales. Multivariate logistic regression analyses were conducted after adjustment for stroke subtype, age, PVH, DWMH, hypertension, dementia, and use of platelet aggregation inhibitors. Additionally, we examined the association between cerebral microbleeds and other covariates using a Pearson's correlation analysis. Results: Amongst 389 patients, 67 patients had a single microbleed and 93 had multiple microbleeds. The prevalence of microbleeds was 83% amongst 53 patients with intracerebral hemorrhage (ICH), 49% amongst 173 with infarction, and 20% amongst 163 without any type of stroke. In the multivariate analyses, the odds ratio (95% CIs) of microbleed detection was 10.1, (4.12-24.8) for ICH, 2.33 (1.12-4.85) for atherosclerotic infarction, 1.66 (1.10-2.48) for PVH, and 1.49 (1.02-2.19) for DWMH. In the Pearson's correlation analysis, cerebral microbleeds were closely related to PVH (Pearson's correlation coefficient; 0.48) and DWMH (0.37), compared with age (0.16). Conclusions: High-grade PVH, high-grade DWMH, ICH, and atherosclerotic infarction were significantly independent predictors for cerebral microbleeds. In addition, we found that the grades of PVH and DWMH have a closer association with the number of cerebral microbleeds than age.

Heart failure is a typical age-associated disease. However, the mechanism by which heart function declines and heart failure increases in association with age is not clear. Recent advances in basic science clarify several important mechanisms of aging. The mechanisms identified are likely to serve as substrates by which heart function declines and predisposes elderly people to heart failure. One such mechanism is insulin/insulin-like growth factor (IGF)-1 signaling. Suppression of insulin/IGF-1 signaling prevents cardiac aging associated with improved protein homeostasis in the heart. However, the role of insulin/IGF-1 signaling in heart diseases is likely to be pleiotropic, and both protective and sensitizing effects have been described in different contexts. Reduction in function of extra-cardiac organs is likely to be another important mechanism by which heart failure increases with aging, since heart failure is a multiple organ system disease. © 2012 Japanese College of Cardiology.

Background There have been extensive studies regarding which types of T lymphocytes are involved in psoriasis vulgaris (PV). However, it has remained unclear which types of T lymphocytes might directly contribute to psoriasiform epidermal and vascular hyperplasia. Objectives To understand the role of T-cell receptor (TCR)Vα24+ invariant natural killer (iNK)T cells in the development of PV. Methods Seventeen patients were enrolled in this study. Using biopsy samples of PV plaques, TCRVα24+ iNKT cells were investigated regarding their cytokine production to understand their roles in development of disease. Results The number of interferon (IFN)-γ+ iNKT cells correlated with the length of the psoriasiform hyperplasia rete ridge and the Psoriasis Area and Severity Index. IFN-γ+ iNKT cells in psoriatic skin exhibited higher C-C chemokine receptor (CCR)5 expression, and the amount of C-C chemokine ligand (CCL)5, a ligand for CCR5, was increased in capillary veins of psoriasis plaques. CCR5+ iNKT-cell numbers significantly correlated with the number of capillary vein endothelial cells expressing CCL5 in PV. Furthermore, the number of CCL5+ capillary veins correlated with the maximum rete ridge length. Conclusions IFN-γ/CCR5 expression in iNKT cells and CCL5 expression in vessels of dermal papillae correlate with the development of psoriasiform hyperplasia and microabscess. We propose that these iNKT cells may become useful targets for development of novel therapeutic approaches to PV. What's already known about this topic? Natural killer (NK)T cells are present in psoriasis plaques, and injection of NKT cells into transplanted psoriatic skin drives lesion formation. Imbalance of interferon (IFN)-γ and interleukin (IL)-4 contributes to lesion development. Injection of IL-4 into the plaque ameliorates psoriasis. What does this study add? Invariant NK (iNK)T-cell number correlates with the length of the rete ridge, and with the Psoriasis Area and Severity Index, epidermal hyperplasia and degree of microabscess formation. iNKT cells in psoriatic skin have higher CCR5 expression, and the CCR5+ iNKT-cell count correlates with that of CCL5+ capillaries in dermal papillae. The CCL5+ capillary endothelial cell count correlates with epidermal hyperplasia. © 2013 British Association of Dermatologists.

Background-The purpose of this study was to evaluate the long-term safety of the Igaki-Tamai stent, the first-in-human fully biodegradable coronary stent made of poly-l-lactic acid. Methods and Results-Between September 1998 and April 2000, 50 patients with 63 lesions were treated electively with 84 Igaki-Tamai stents. Overall clinical follow-up (>10 years) of major adverse cardiac events and rates of scaffold thrombosis was analyzed together with the results of angiography and intravascular ultrasound. Major adverse cardiac events included all-cause death, nonfatal myocardial infarction, and target lesion revascularization/target vessel revascularization. During the overall clinical follow-up period (121±17 months), 2 patients were lost to follow-up. There were 1 cardiac death, 6 noncardiac deaths, and 4 myocardial infarctions. Survival rates free of all-cause death, cardiac death, and major adverse cardiac events at 10 years were 87%, 98%, and 50%, respectively. The cumulative rates of target lesion revascularization (target vessel revascularization) were 16% (16%) at 1 year, 18% (22%) at 5 years, and 28% (38%) at 10 years. Two definite scaffold thromboses (1 subacute, 1 very late) were recorded. The latter case was related to a sirolimus-eluting stent, which was implanted for a lesion proximal to an Igaki-Tamai stent. From the analysis of intravascular ultrasound data, the stent struts mostly disappeared within 3 years. The external elastic membrane area and stent area did not change. Conclusion-Acceptable major adverse cardiac events and scaffold thrombosis rates without stent recoil and vessel remodeling suggested the long-term safety of the Igaki-Tamai stent. © 2012 American Heart Association, Inc.

We report a case of fungemia caused by Scedosporium prolificans, an emerging pathogen. An 83-year-old man with myelodysplastic syndrome (MDS) and agranulocytosis was admitted for pneumonia in January 2009. He was treated with meropenem, minocycline, and gamma-globulin for pneumonia and G-CSF and platelet transfusion for MDS. Although he recovered from pneumonia as neutrophil count increased, intermittent fever continued. On hospital day 17, blood culture yielded fungal colonies indicating S. prolificans. Voriconazole was started immediately, but the man's general condition deteriorated with cerebral infarction and he died of cerebral hemorrhage on hospital day 65. Attention must therefore be paid to the increasing scedosporiosis incidence in Japan.

Mycotic aortic aneurysm due to Streptococcus pneumoniae is rare. The case of we report occurred in 62-year-old man with no antecedent infection admitted for appetite loss and lower leg edema. Chest and abdominal computed tomography, blood culture, and gene analysis to detec arterial wall pneumococci led to a diagnosis of mycotic aortic aneurysm caused by S. pneumoniae. The man had a graft replaced and was administered antibiotics. He remains well and infection-free 12 months after surgery. We also review the literature on these aortic aneurysms.

A 33-year-old male with hereditary deficiency of antithrombin III (AT III) was diagnosed with annuloaortic ectasia and scheduled for the aortic root replacement. As perioperative anticoagulation, AT III was administered to have its activity≥70% in addition to heparin. During the operation with cardiopulmonary bypass, 3,000 IU of AT III concentrate was infused, and there was no hemorrhagic complication. After the operation low-molecular-weight heparin was used instead of unfractionated heparin to avoid bleeding. However, renal infarction occurred on postoperative day 11. Heparin was continuously given in combination with 1,500 IU/day of AT III concentrate until oral warfarin reached within therapeutic range. The patient recovered without further sequelae. Cardiac surgery might be safely performed in patients with AT III deficiency by replenishing AT III concentrate to keep its activity higher than 80%.

Cobb syndrome is a rare, noninherited, neurocutaneous disease characterized by vascular abnormality of the spinal cord and is associated with vascular lesions in the skin at the same metamere. The majority of spinal vascular lesions are arteriovenous malformations, and skin lesions are mostly port-wine angiomas. The authors report the first case of multiple intramedullary cavernous angiomas (CAs) accompanied by skin CAs within the same metamere. A 42-year-old man presented with an acute onset of gait disturbance, low-back pain, and urinary incontinence. Magnetic resonance imaging of the thoracolumbar spine showed homogeneously enhanced lesions on a contrast-enhanced T1-weighted image and a hypointense area on a T2*-weighted image surrounding this enhanced lesion, between the T-12 and S-1 levels. Purple protruding skin lesions were detected on the left side of his gluteal region. The patient received a laminectomy followed by evacuation of a hematoma and partial removal of the tumor, which completely resolved his neurological symptoms. Pathological examinations showed that the spinal and skin lesions were CAs, suggesting that these vascular lesions developed congenitally. Cavernous angiomas associated with Cobb syndrome present with multiple lesions spanning more than 3 vertebral levels, making it difficult to completely resect these tumors. Although Cobb syndrome is an uncommon disease entity, it should be considered if a patient manifesting with neurological deficits has skin vascular lesions, including CAs. ©AANS, 2014.

There are many excellent innovative basic studies from universities, institutes and hospitals in Japan. However, fundamental studies are not necessarily tied to clinical practice. It is sometimes difficult to use the latest medicine that has been already put to practical use abroad. We have discussed the strategy to connect advanced technology with practical use on several occasions. In this paper the structure and process of clinical trials and advanced medical care will be introduced.
