Abstract
BACKGROUND Letrozole, an aromatase inhibitor, is used to treat breast cancer in postmenopausal women. Tumor lysis syndrome (TLS) is a complication that can trigger multiple organ failure caused by the release of intracellular nucleic acids, phosphate, and potassium into the blood due to rapid tumor cell disintegration induced by drug therapy. TLS is uncommon in solid tumors and occurs primarily in patients receiving chemotherapy. Herein, we report a rare occurrence of TLS that developed in a patient with locally advanced breast cancer following treatment with letrozole. CASE PRESENTATION An 80-year-old woman with increased bleeding from a fist-sized left-sided breast mass presented to our hospital. Histological examination led to a diagnosis of invasive ductal carcinoma of the luminal type. The patient refused chemotherapy and was administered hormonal therapy with letrozole. Seven days after letrozole initiation, she complained of anorexia and diarrhea. Blood test results revealed elevated blood urea nitrogen (BUN) and creatinine (Cr) levels, and she was admitted to our hospital for intravenous infusions. On the second day after admission, marked elevations of LDH, BUN, Cr, potassium, calcium, and uric acid levels were observed. Furthermore, metabolic acidosis and prolonged coagulation capacity were observed. We suspected TLS and discontinued letrozole, and the patient was treated with hydration, febuxostat, and maintenance hemodialysis. On the third day after admission, her respiratory status worsened because of acute respiratory distress syndrome associated with hypercytokinemia, and she was intubated. On the fourth day after admission, her general condition did not improve, and she died. CONCLUSIONS Although TLS typically occurs after chemotherapy initiation, the findings from the present case confirm that this syndrome can also occur after hormonal therapy initiation and should be treated with caution.

Abstract
OBJECTIVE There is no established consensus or guidelines for wound management after revascularization for patients with chronic limb-threatening ischemia (CLTI) without severe infection. This study is designed to evaluate the clinical effect of the wound management strategy on toe wounds after revascularization for CLTI. METHODS This retrospective cohort study was performed at eight institutions affiliated with Keio University School of Medicine in Japan and included 261 patients who underwent revascularization for CLTI between April 2019 and July 2021. We identified 132 patients with toe wounds from the database who had restored in-line blood flow to the foot. Patients were divided into two groups by the timing of toe resection after revascularization, which dictated the wound management policy. Group A (62 patients) underwent early toe amputation for suspected osteomyelitis, whereas group B (70 patients) underwent watchful waiting. The primary outcome was wound healing after revascularization; the secondary outcome was major amputation. We compared outcomes between groups A and B after propensity score matching. RESULTS Using propensity score matching, each patient in group A (33 patients) was matched with a patient in group B (33 patients). Wound healing in matched group A was significantly better than that in matched group B (respectively: 1-year wound healing rate: 90.0% vs 68.2%, P < .001; median wound healing time: 65 days vs 258 days, P < .01). Although five major amputations were necessary in matched group B, none were required in matched group A (P = .05). The high rate of major amputations in group B was attributed to the sudden exacerbation of infection. Limb salvage rate in matched group A exceeded matched group B (100.0% vs 90.5%: 1-year limb salvage rate, P = .02). CONCLUSIONS Early toe amputation for highly suspected osteomyelitis in patients with CLTI with toe wounds may expedite wound healing compared with watchful waiting, potentially avoiding unnecessary major amputation. Considering the wound management strategy is crucial when evaluating wound healing outcomes in patients with CLTI with revascularization.

Abstract
IgG4-related mastitis is an extremely rare IgG4-related sclerosing disease involving the breast that must be differentiated from breast cancer. There is currently no consensus regarding the optimal treatment strategies. Here, we report a case of IgG4-related mastitis followed up without excision or steroid therapy. Although the association between IgG4-related mastitis and breast cancer remains unclear, regular follow-up imaging and measurement of serum concentrations of disease activity markers may allow for follow-up without excision or steroid therapy.

Abstract
In recent years, endovascular treatment has become the first-line revascularisation method for aortoiliac artery occlusive disease. Rarely, aortoiliac artery occlusive disease may be associated with stenosis of the external iliac artery (EIA) that suggested pseudo-stenosis. We describe a case of aortoiliac artery occlusive disease with EIA stenosis without calcification or atheroma. Stent grafts were inserted from the abdominal aorta to the bilateral common iliac arteries. Pre-operative computed tomography and intravascular ultrasound findings confirmed the absence of calcification or atheroma in both EIA, suggesting that the EIA had developed pseudo-stenosis. Following endovascular treatment, the EIA diameter recovered only with balloon dilation after inflow improvement. Consideration is necessary when placing an easy stent graft in the narrow EIA during endovascular treatment for aortoiliac artery occlusive disease with EIA stenosis to avoid a potential stent graft diameter mismatch.

Abstract
Ruptured phyllodes tumors, though extremely rare, can necessitate emergency surgery in certain cases, particularly those with active bleeding. A 51-year-old woman presented to our hospital with a newly identified mass in her right breast that developed over the past two months. The tumor had ruptured through the paramammary nipple. While initially diagnosed with a phyllodes tumor and scheduled for elective surgery, she experienced active bleeding from the ruptured tumor, leading to a drop in hemoglobin levels. An emergency right simple mastectomy was performed to control the bleeding. Postoperatively, no complications or recurrences were observed. Phyllodes tumors, which are characterized by rapid growth, may present with active bleeding following rupture and may require emergency surgery.

Abstract
Objective: In this study, we aim to evaluate the efficacy of early closed toe amputation on the wound management of toe ulcers with suspected osteomyelitis after revascularization for chronic limb-threatening ischemia (CLTI). Methods: This retrospective study included patients who have underwent revascularization for toe ulcers associated with CLTI at Shizuoka Red Cross Hospital from 2015 to 2021. Wound management comprised early closed toe amputation for toe ulcers with suspected osteomyelitis (19 toes in 17 patients) or conservative treatment (35 toes in 26 patients). The primary endpoint was wound healing after revascularization. We compared the wound healing rate at 90 days and median healing time of early closed toe amputation versus conservative treatment. Results: Compared with the conservative treatment, early closed toe amputation was able to achieve a better wound healing rate at 90 days (89.5% vs. 68.6%; P<0.01) and a shorter median healing time (19 days vs. 62 days; P=0.01). Conclusion: There remains no established wound management for toe lesions associated with CLTI. Despite its several disadvantages including wound infection and possible foot deformity, early closed toe amputation for toe ulcers with suspected osteomyelitis can be considered a safe approach in terms of wound management.

Abstract
PURPOSE To compare the long-term outcomes of the most widely used third-generation stent grafts, the Endurant and Excluder stent grafts, in Japanese patients using a multicenter registry. MATERIALS AND METHODS A retrospective analysis of endovascular aneurysm repairs for abdominal aortic and iliac artery aneurysms using either the Endurant or the Excluder stent grafts from January 2012 to July 2019 at 10 Japanese hospitals was performed. RESULTS A total of 332 and 378 repairs using the Endurant and Excluder stent grafts, respectively, were analyzed. Although the patients' characteristics were generally similar in the two groups, the Endurant group exhibited significantly shorter (Endurant: 31.5±18.6 mm, Excluder: 37.4±21.0 mm; p<0.001), larger (Endurant: 22.4±4.2 mm, Excluder: 21.7±3.8 mm; p=0.029), and more reversed tapered (Endurant: 12.1%, Excluder: 5.8%; p=0.003) proximal necks. The incidence of instructions for use (IFU) violations was similar between the two groups (Endurant: 59.0%, Excluder: 54.5%; p=0.223). However, the Endurant group had significantly more proximal neck-related IFU violations (54.1% and 46.3%, respectively; p=0.039), more access-related IFU violations (8.1% and 4.0%, respectively; p=0.019), and fewer bilateral hypogastric artery embolizations (5.1% and 9.3%, respectively; p=0.035) compared with the Excluder group. The incidence of intraoperative (Endurant: 3.6%, Excluder: 3.7%; p=0.950) and perioperative complications (Endurant: 3.6%, Excluder: 3.4%, p=0.899) was equivalent in the two groups. However, there was a significantly higher incidence of postoperative type II endoleaks in the Excluder group (Endurant: 28%, Excluder: 46.0%, p<0.001). Aneurysm sac regression was more frequent in the Endurant group (Endurant: 40.7%, Excluder: 31.7%, p=0.013). The Endurant group also had significantly higher rates of sac increase (Endurant: 13.0%, Excluder: 7.7%, p=0.020). Kaplan-Meier curve and log-rank analyses revealed no statistical differences in late complications (p=0.868) and overall survival (p=0.926). CONCLUSIONS There were no statistically significant differences between the Endurant and the Excluder stent grafts in terms of intraoperative, perioperative, and late complication rates; however, the anatomical characteristics of the patients were significantly different.

Abstract
Type B aortic dissection (TBAD) is a rare but catastrophic complication of endovascular aneurysm repair (EVAR). We report two cases of TBAD occurring in the perioperative period of EVAR. The intraoperative and postoperative courses were unremarkable. Routine postoperative computed tomography angiography (CTA) revealed TBAD. Conservative treatment was successful, and no adverse aortic events occurred. TBAD that occurs in the perioperative period is likely to be iatrogenic in origin, uncomplicated, and managed with medical therapy: its prognosis is better than when the condition develops in the midterm postoperative period.

Abstract
Calorie restriction (CR) is to reduce food intake without malnutrition and is sometimes
adopted intentionally to reduce body weight for improving health. CR has been known to
prolong the lifespan in several animal models such as nematodes, flies, and mice. While it
is not feasible to implement long term CR in humans, the intake of specific food
substances that produce the same effect as CR can result in significant health benefits to
humans. This paper highlights the need for promoting research on such calorie restriction
mimetics (CRMs). This scientific opinion suggests that the promotion of research on
CRMs derived from foods and food resources has the potential to enhance health and
prolong life span. Collaboration between researchers from the fields of food science and
those working on CRMs has the potential to promote good health and enhance human
longevity in the aging society.

Abstract
Few data regarding popliteal artery entrapment syndrome (PAES) is available in Japan. In this study, we investigated incidence, diagnosis and treatment of PAES in current vascular practice. A retrospective analysis of all patients with PAES visiting 31 participating institutes between 2003 and 2015 was conducted. Thirty-five limbs (28 patients) were identified during the 13-year study period, and the incidence of PAES was 0.12% of all peripheral artery disease cases revascularized. Mean age was 32.0 ± 16.9 years old, and 60 and more years old was 10.7%. Also, 92.9% were male and 39.3% were athletes. Most frequent initial symptoms were intermittent claudication in 23 limbs (65.7%); 4 limbs (11.4%) had chronic limb-threatening ischemia. CT scan was most frequently (94.3%) used for the diagnostic imaging followed by MRI (45.7%) and duplex ultrasound (45.7%). Stress test such as dorsal flexion during duplex ultrasound was used only in 28.6%. Thirty-two limbs (91.4%) received surgical treatment, including 23 arterial reconstructions (71.9%); there were no major perioperative complications. All patients achieved improvement of their symptoms, and the average ankle brachial index increased from 0.69 ± 0.22 to 1.00 ± 0.14 post-surgery. The average postoperative follow-up period was 26.0 months with only one reintervention during the follow-up. In conclusion, PAES was a rare condition and traditional surgical treatment was solid. However, given a broad spectrum of clinical feature of PAES and less usage of diagnostic duplex ultrasound with stress test, there might be a miss- or delayed diagnosis of PAES even in the current vascular practice.

Abstract
Objective: The purpose of this study was to evaluate the effect of atheromatous aorta on thromboembolic complications after endovascular aortic aneurysm repair (EVAR) and to assess the risk factors for these complications. Materials and Methods: This retrospective study included patients who underwent EVAR for an abdominal aortic aneurysm at the Shizuoka Red Cross Hospital from 2007 to 2018. We defined atheromatous aorta as a thoracic shaggy aorta or abdominal aorta with neck thrombus. The main outcome was renal dysfunction and peripheral embolization (thromboembolic complications). We compared the incidence of thromboembolic complications between patients with normal aorta and atheromatous aorta. Moreover, we assessed the risk factors associated with thromboembolic complications in patients with atheromatous aorta. Results: Patients with atheromatous aorta had significantly more thromboembolic complications, such as renal dysfunction (24.5% vs. 3.9%; P<0.001) and peripheral embolization (12.3% vs. 0.0%; P<0.001) than those with normal aorta, respectively. We identified no risk factors associated with thromboembolic complications in patients with atheromatous aorta. Conclusion: Atheromatous aorta increases the risk of thromboembolic complications after EVAR. However, there is no established therapy for these thromboembolic complications. Further studies are necessary to determine the appropriate therapy, including appropriate preoperative medication, to prevent these complications.

Abstract
Background Dental professionals have so many opportunities to use injection needles and sharp instruments during dental treatment that they face an increased risk of needlestick injuries. This retrospective study reports the utilization and clinical outcomes of occupational post-exposure prophylaxis (PEP) with anti-retroviral agents after being potentially exposed to HIV at the dental departments of Hiroshima University Hospital. Objective This study reports the utilization and clinical outcomes of occupational post-exposure prophylaxis (PEP) with antiretroviral agents after being potentially exposed to HIV at dental departments of Hiroshima University Hospital. Methods Data on the clinical status of HIV-infected source patients and information on HIV-exposed dental professionals from 2007 to 2018 were collected. Results Five dentists with an average experience of 5.6 years (1-15 years) were exposed. The averaged CD4-positive cell number and HIV-RNA load were 1176 (768-1898) /μl and less than 20 copies/ml, respectively, in all the patients. Two of the five HIV exposed dentists received PEP. Three months after the exposures, all of their results were negative in HIV antibody/antigen tests. Conclusion These data might support the concept of “undetectable equals untransmittable”, although HIV exposure in this study was not through sexual transmission.

Abstract
Stroke can be a cause of death, while in non-fatal cases it is a common cause of various disabilities resulting from associated brain damage. However, whether a specific periodontal pathogen is associated with increased risk of unfavorable outcome after stroke remains unknown. We examined risk factors for unfavorable outcome following stroke occurrence, including serum antibody titers to periodontal pathogens. The enrolled cohort included 534 patients who had experienced an acute stroke, who were divided into favorable (n = 337) and unfavorable (n = 197) outcome groups according to modified ranking scale (mRS) score determined at 3 months after onset (favorable = score 0 or 1; unfavorable = score 2-6). The associations of risk factors with unfavorable outcome, including serum titers of IgG antibodies to 16 periodontal pathogens, were examined. Logistic regression analysis showed that the initial National Institutes of Health stroke scale score [odds ratio (OR) = 1·24, 95% confidence interval (CI) = 1·18-1·31, P < 0·001] and C-reactive protein (OR = 1·29, 95% CI = 1·10-1·51, P = 0·002) were independently associated with unfavorable outcome after stroke. Following adjustment with those, detection of the antibody for Fusobacterium nucleatum ATCC 10953 in serum remained an independent predictor of unfavorable outcome (OR = 3·12, 95% CI = 1·55-6·29, P = 0·002). Determination of the antibody titer to F. nucleatum ATCC 10953 in serum may be useful as a predictor of unfavorable outcome after stroke.

Abstract
BACKGROUND Although the use of aneurysmal common iliac artery (CIA) as the landing zone during endovascular aortic aneurysm repair EVAR remains an essential procedure, this procedure may increase the risk of late complications such as ongoing CIA dilatation and type Ib endoleak (CIA-related complications). We hypothesized that incomplete sealing of the aneurysmal CIA segment during EVAR could increase the incidence of CIA-related complications. In this study, we evaluated the midterm results of EVAR with aneurysmal CIA used as the landing zone and assessed the importance of distal sealing in this procedure. METHODS We retrospectively reviewed all cases of endovascular aneurysm repair using CIA as landing zone between 2007 and 2015 that had at least 3 years' follow-up. We defined aneurysmal CIA as maximum diameter ≥18 mm. The main outcome was the incidence of CIA-related complications. We compared midterm results between normal CIA and aneurysmal CIA. Next, we analyzed risk factors for CIA-related complications in aneurysmal CIA. RESULTS Four complications occurred in normal CIA (mean follow-up, 66.5 ± 22.1 months); 21 occurred in aneurysmal CIA (mean follow-up, 62.2 ± 20.5 months). The 5-year portion of freedom from CIA-related complications was 97.3% in normal CIA and 69.4% in aneurysmal CIA (P < 0.001). Multivariable analysis in aneurysmal CIA showed that unsealed CIA segment length was only risk factor for CIA-related complications. Given the receiver operating characteristic curve results, we defined the unsealed CIA segment ≥10 mm as incomplete sealing. The hazard ratio for incomplete sealing associated with CIA-related complications was 3.92 (95% confidence interval 1.62-9.46, P = 0.02). CONCLUSIONS Use of aneurysmal CIA as landing zone increases the risk of CIA-related complications. However, maximum sealing of the aneurysmal CIA segment could prevent these complications.

Abstract
OBJECTIVE/BACKGROUND It was hypothesised that a helical stent with expanded polytetrafluoroethylene (ePTFE) grafts could provide a preventive effect for external iliac artery (EIA) limb occlusion following endovascular aortic aneurysm repair (EVAR). Therefore, a post-hoc analysis of a Japanese multicentre database was conducted to assess the impact of the stent graft design on EIA limb occlusion rates. METHODS Patients who underwent EVAR with EIA limb deployment between 2008 and 2016 were evaluated. The stent graft limbs were divided into two groups: group A comprised stent graft limbs made of a helical stent with ePTFE grafts (Excluder; n = 255), and group B comprised stent graft limbs made of a Z stent with polyester grafts (Zenith, Flex and Endurant; n = 173). The main outcome was the incidence of limb occlusion and severe limb stenosis (EIA related limb complications). The risk factors for EIA related limb complications were analysed and the midterm results between groups A and B compared. Fine-Gray generalisation of the proportional hazards model was used after propensity score matching to calculate the hazard ratio (HR). RESULTS One complication occurred in group A and 10 complications occurred in group B. The risk factors for EIA related limb complications for the entire group were a stent graft limb size ≤10 mm (HR 5.41; p = .01) and inclusion in group B (HR 14.9; p = .009). After propensity matching, group A (n = 159) was matched with group B (n = 159). The cumulative incidence function of EIA related limb complications at five years was 0.66% in group A and 7.8% in group B (HR 8.67; p = .039). CONCLUSION Stent graft design can affect limb patency in EIA limb deployment. When EIA limb deployment is necessary for patients with a small EIA, such as Japanese patients, stent graft limbs made of a helical stent with ePTFE should be used to reduce the risk of limb occlusion.

Abstract
The aim of the study was to evaluate the oral environment and the taste function of Japanese HIV-infected patients treated with antiretroviral therapy. Their median age of 73 patients taking anti-HIV drugs was 46 years. The median period of taking anti-HIV drugs was 30 months. The oral condition was evaluated by measurement of oral moisture, amount of saliva secretion, the number of oral bacteria, presence of oral candida, a taste test, and the number of missing teeth. The levels of oral moisture and secreted saliva were significantly lower in the HIV-infected group than in the healthy volunteer (control) group. The HIV-infected group showed a more robust decrease in taste sensation than the control group. The number of missing teeth was significantly higher in the HIV-infected group than in the control group. Furthermore, all of the evaluated oral conditions were worse in the HIV-infected patients whose CD4+ T lymphocyte counts were less than 500/mm3 than in the control group. It became clear that the patients taking anti-HIV drugs, especially the CD4+ count < 500/mm3 group, had a deteriorated oral environment and dysgeusia, suggesting that the management of oral hygiene is necessary to maintain oral health, which leads to systemic health.

Abstract
Heparin-binding protein 17 (HBp17)/fibroblast growth factor-binding protein-1 (FGFBP-1) was first purified from medium conditioned by A431 cells for its capacity to bind to fibroblast growth factors 1 and 2 (FGF-1 and -2). Among FGF family members, FGF-2 is a potent mitogen for various cell types, including vascular endothelial cells, fibroblasts, and cancer cells such as oral squamous cell carcinoma (OSCC) cells. Besides being well known in bone metabolism, the active form of vitamin D3, i.e., 1α,25(OH)2D3 (1,25D3), was reported to have protective effects for heart disease and cancer. Previously, we reported that 1,25D3 inhibited HBp17/FGFBP-1 expression in OSCC cell lines through NF-κB inhibition (IκBα activation) and resulted in the inactivation of FGF-2. In this study, we examined the potential anti-tumor effect of ED-71, an analog of 1α,25(OH)2D3, for squamous cell carcinoma cells in vitro and in vivo. The cell lines used were OSCC cell lines (NA-HO-1-n-1 and UE-HO-1-u-1), established from oral cancer patients in our laboratory, and an epidermoid carcinoma/SCC cell line (A431). The growth assay in serum-free culture revealed that ED-71 inhibited the growth of the cancer cell lines in a dose-dependent manner. In addition, ED-71 suppressed HBp17/FGFBP-1 expression by inhibiting the NF-κB pathway as did 1,25D3. Furthermore, a luciferase reporter assay revealed that the promoter activity of HBp17/FGFBP-1 (region between -217 and +61) was down-regulated by ED-71. Oral administration of ED-71 significantly inhibited the growth of A431-derived tumors in athymic nude mice. Immunohistochemical analysis revealed that the expression of HBp17/FGFBP-1, FGF-2, CD31, and Ki-67 in the tumors of ED71-treated group was down-regulated in comparison to control. These results suggest that ED-71 possesses potential anti-tumor activity for SCCs both in vitro and in vivo. This compound may act directly on the tumor cells or on endothelial cells by modulating the tumor microenvironment.

Abstract
Herein, we report a rare case of type B aortic dissection that occurred after endovascular aortic aneurysm repair (EVAR). A 66-year-old man underwent successful EVAR for an abdominal aortic aneurysm (AAA). Computed tomography (CT) 2 years after EVAR showed a type B aortic dissection with stent-graft migration and AAA expansion. Juxtarenal aortic expansion precluded simple stent-graft placement. He underwent hepato-spleno-renal bypass followed by stent-graft placement just below the superior mesenteric artery. Postoperative CT showed no endoleaks. This case reconfirms the importance of regular follow-up after EVAR and illustrates the usefulness of a hybrid approach.

Abstract
We have previously reported that 1,25(OH)2D3 inhibits NF-κB activity and thus inhibits growth of OSCC cells in serum-free culture and down-regulates HBp17/FGFBP-1 expression, which is important for cancer cell growth and angiogenesis. Here, we have investigated the effects of ED-71, an analog of vitamin D3 (VD) on OSCC cell lines in serum-free culture. It is known that ED-71 has a stronger inhibitory effect on bone resorption compared to VD and other VD analogs. To the best of our knowledge, there was no report examining the potential of ED-71 as an anti-cancer agent for OSCC. We found that ED-71 is able to inhibit the growth of cancer cell lines at a concentration of hundred times lower than calcitriol. As Cyp24A1 was reportedly induced in cancer cells, we measured the expression of CYP24A1 in OSCC cell lines (NA and UE), A431 epidermoid carcinoma and normal fibroblast cell (gfi) in serum-free culture. As a result, CYP24A1 mRNA and the protein expression in the OSCC cells treated with ED-71 increased in a dose-dependent manner. However, in vivo experiment, in which the A431 cells were implanted in mice, tumor formation was reduced by the ED-71 treatment with no significant difference between Cyp24A1 expression in the tumors of ED-71-treated and control group, as analyzed by western blotting and immunohistochemistry. These results suggest that ED-71 is a potential anti-cancer agent for OSCC.

Abstract
OBJECTIVE A large number of individuals have halitosis. The total amount of volatile sulfur compounds, which are the main cause of halitosis, has been correlated with periodontitis following bacterial infection. In this study, Porphyromonas gingivalis (Pg), a major periodontopathogenic bacterium, was isolated from patients with halitosis by the amplification of 16S rRNA, and the ability of isolated Pg to produce methyl mercaptan (CH3 SH) was determined to clarify the relationship between halitosis and Pg infection. MATERIALS AND METHODS CH3 SH concentrations were measured in patients using Oral Chroma. The production of CH3 SH by Pg standard and clinical strains was also measured in vitro. Real-time PCR was performed to compare the expression of mgl mRNA (which encoded l-methionine-a-deamino-g-mercaptomethane-lyase) among the Pg strains. The production of CH3 SH and the expression of mgl mRNA were also determined to assess the effects of oriental medicine. RESULTS The production of CH3 SH and the expression of mgl mRNA strongly correlated with each other in the presence of l-methionine. The expression of mgl mRNA by Pg W83 was strongly inhibited by magnoliaceae. CONCLUSION The production of CH3 SH was correlated with the expression of mgl. Furthermore, the oriental medicine, magnoliaceae, may represent a potential treatment for halitosis.

Abstract
Bisphosphonates (BPs) have been used in medical practice for the treatment of osteoporosis, bone metastasis, and multiple myeloma. Although many studies have been published, the treatment and prognosis of bisphosphonate-related osteonecrosis of the jaw (BRONJ) remain unclear. This study included 59 patients with BRONJ: 29 had taken oral BPs and 30 had taken intravenous (IV) BPs. All received conservative treatments. When separated sequestra were seen, a sequestrectomy was performed. Segmental mandibular resection was performed when pathological fractures were diagnosed. The outcomes of treatments were compared between groups. For patients treated with oral rinses or mandibular resection, the number in whom clinical healing was observed did not differ between the oral BP and IV BP groups. With regard to sequestrectomy, 94% of patients in the oral BP group showed improvement with this treatment compared to 50% in the IV BP group. The number of patients in whom clinical healing of BRONJ was achieved was statistically better in the oral BP group than in the IV BP group after 6 months of treatment (P<0.001). The results showed that >90% of patients treated with oral BPs could be cured. However, 50% of patients treated with IV BPs did not show an improvement. Additional research is needed to further increase the therapeutic efficacy for the resolution of BRONJ.

Abstract
We describe a David operation in a 62-year-old renal transplant recipient with valsalva aneurysm and concomitant aortic insufficiency. The risk of postoperative infection seemed significant because he was receiving immunosuppressive therapy; thus, David operation was performed. He recovered uneventfully. David operation appears to be an attractive alternative in transplant recipients.

Abstract
A 25-year-old woman committed suicide with a high-rise fall and presented hypovolemic shock caused by blunt thoracic, abdominal injury. Enhanced computed tomography scan showed the pelvic hemorrhage and the transection of the descending thoracic aorta. After urgent transcatheter arterial embolization to stabilize bleeding from pelvic fracture, the thoracic aortic injury was treated with endovascular aortic repair using a GORE TAG endograft. She recovered from her injuries, and there was no evidence of endoleak in the follow-up computed tomography scan. In the treatment of traumatic aortic injury with associated severe injuries, the management of bleeding from associated injuries is important.

Abstract
An 76-year-old man was referred to our hospital due to right hydrothorax. The diffuse thickening of parietal pleura with increased fluoro-2-deoxy-D-glucose (FDG) uptake was noted by computed tomography (CT) and positron emission tomography (PET). Surgical biopsy was performed and the tumor was diagnosed as mucosal associated lymphoid tissue (MALT) lymphomas of parietal pleura origin by pathology. Complete remission was achieved by postoperative chemotherapy (R-CHOP), and the patient is now alive without recurrence.

Abstract
The heparin binding protein 17/fibroblast growth factor-binding protein-1 (HBp17/FGFBP-1, GenBank accession no. NP-005121) has been reported to enhance angiogenesis as well as promotes tumor growth in vivo. Furthermore, this molecule was found to be highly expressed in the tissue and cell lines of oral squamous cell carcinoma (OSCC). 1α,25(OH)2D3 is used to study its potential to curb the expression of HBp17/FGFBP-1 in cancer cells. Consequently, we found that HBp17/FGFBP-1 mRNA and protein levels were significantly down-regulated. In this present study, we show that this event takes place via the NF-κB pathway since mRNA and protein levels of this pathway regulator, IκBα, were found to be significantly up-regulated. Furthermore, the promoter activity of HBp17/FGFBP-1 (region between -217 and +61) measured by a luciferase reporter assay was down-regulated following treatment. Silencing of VDR with siRNA showed the effect of 1α,25(OH)2D3 on HBp17/FGFBP-1. Based on these findings, we concluded that 1α,25(OH)2D3 down-regulated HBp17/FGFBP-1 expression via NF-κB.

Abstract
Profunda femoris artery aneurysms (PFAAs) are rare and difficult to diagnose in the early stage. They are often found due to the presence of complicated conditions, such as rapid expansion, rupture, or acute lower limb ischemia. Surgical procedures such as aneurysmectomy and endoaneurysmorrhaphy tend to be technically challenging because of the patient status and the extent of the aneurysm. We experienced three cases of PFAAs that were treated by proximal ligation (PL) without complete control of the distal branches. The exclusion of PFAAs was confirmed by duplex ultrasound or angiography at the end of the operation. There was no mortality in the perioperative period. During a 12-month follow-up, all cases exhibited complete exclusion of aneurysms with marked size reduction. Based on these findings, we propose that PL, with a careful follow-up for PFAA exclusion and distal limb circulation, could be an alternative treatment for complicated PFAAs.

Abstract
OBJECTIVE To evaluate outcomes after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) with neck thrombus. METHODS We retrospectively reviewed patients who underwent EVAR for AAA at our institution from 2007 to 2011. Patients with ruptured AAA, chronic renal failure, or hostile neck characteristics other than thrombus were excluded. Patients were divided into 2 groups: group T (with neck thrombus) and group N (without neck thrombus). We compared complications and mid-term outcomes. RESULTS There were no differences in success rates between the groups, but there were higher rates of thromboembolic complications such as distal embolization (20% vs 0%, P = .02) and renal dysfunction (36.8% vs 11.1%, P = .03) in group T than in group N. Suprarenal thrombus and suprarenal fixation in the presence of suprarenal thrombus were associated with postoperative renal dysfunction (P = .01). CONCLUSION The EVAR for AAA with neck thrombus is associated with thromboembolic complications.

Abstract
To investigate the trends of antimicrobial resistance in pathogens isolated from surgical site infections (SSI), a Japanese surveillance committee conducted the first nationwide survey. Seven main organisms were collected from SSI at 27 medical centers in 2010 and were shipped to a central laboratory for antimicrobial susceptibility testing. A total of 702 isolates from 586 patients with SSI were included. Staphylococcus aureus (20.4 %) and Enterococcus faecalis (19.5 %) were the most common isolates, followed by Pseudomonas aeruginosa (15.4 %) and Bacteroides fragilis group (15.4 %). Methicillin-resistant S. aureus among S. aureus was 72.0 %. Vancomycin MIC 2 μg/ml strains accounted for 9.7 %. In Escherichia coli, 11 of 95 strains produced extended-spectrum β-lactamase (Klebsiella pneumoniae, 0/53 strains). Of E. coli strains, 8.4 % were resistant to ceftazidime (CAZ) and 26.3 % to ciprofloxacin (CPFX). No P. aeruginosa strains produced metallo-β-lactamase. In P. aeruginosa, the resistance rates were 7.4 % to tazobactam/piperacillin (TAZ/PIPC), 10.2 % to imipenem (IPM), 2.8 % to meropenem, cefepime, and CPFX, and 0 % to gentamicin. In the B. fragilis group, the rates were 28.6 % to clindamycin, 5.7 % to cefmetazole, 2.9 % to TAZ/PIPC and IPM, and 0 % to metronidazole (Bacteroides thetaiotaomicron; 59.1, 36.4, 0, 0, 0 %). MIC₉₀ of P. aeruginosa isolated 15 days or later after surgery rose in TAZ/PIPC, CAZ, IPM, and CPFX. In patients with American Society of Anesthesiologists (ASA) score ≥3, the resistance rates of P. aeruginosa to TAZ/PIPC and CAZ were higher than in patients with ASA ≤2. The data obtained in this study revealed the trend of the spread of resistance among common species that cause SSI. Timing of isolation from surgery and the patient's physical status affected the selection of resistant organisms.

Abstract
60-year-old woman was admitted with an abnormal shadow on the chest roentgenogram. Computed tomography showed atelectasis of the right middle lobe and hilar and mediastinal lymphadenopathy. Bronchoscopic examination revealed an obstruction at the orifice of the right middle lobe bronchus and biopsy was performed. The biopsy suggested malignant lymphoma. A diagnosis of methotrexate-associated lymphoproliferative disorders was suspected because the patient was administered methotrexate to treat the rheumatoid arthritis. The video-assisted thoracoscopic surgery was performed. Histological examination showed no malignancy and sarcoidosis in the peribronchial lymph nodes. The compressed middle lobe bronchus by enlarged lymph nodes was consider to be the cause of the middle lobe atelectasis.

Abstract
An 83-year-old man with a decreasing level of consciousness was carried to the emergency room. Computed tomography (CT) revealed a ruptured aortic arch aneurysm. He was deemed a high risk candidate for conventional surgical repair. The case was treated by a hybrid approach. Endo-exclusion of thoracic aortic aneurysm (TAA) was obtained by implanting stentgrafts from the ascending to descending aorta. The brain circulation was maintained by right to left carotid and to left subcravian artery bypasses combined with" chimney endo-debranching graft" of the innominate artery. This could be a method of choice for the acute patients under similar circumstances.

Abstract
PURPOSE To share our hybrid endovascular experiences using chimney or sandwich stent grafts for acute aortic arch pathologies. METHODS Hybrid procedures for a distal aortic arch aneurysm and an ascending anastomotic aortic aneurysm rupture were reported. Right to left common carotid and left axillar artery bypasses were located. Covered stents were inserted into the inominate artery, with the flow-proximal end located in the ascending (standard chimney) or the descending aortic stent graft (retrograde sandwich). RESULTS Both cases had no signs of brain ischemia. Aneurysms are decreasing in size. CONCLUSION Chimney and sandwich techniques were technically feasible in the complex and acute situations.

Abstract
A 79-year-old woman presented with sustained thoracolumbar back pain. Contrasted computed tomography (CT) showed a thoracoabdominal aortic aneurysm (TAAA: type I of Crawford classification) and an abdominal aortic aneurysm (AAA) that were not ruptured. Considering her age, the placement of an endovascular stent graft was performed for TAAA at the possible sacrifice of the celiac (CA) and superior mesenteric arteries (SMA). In order to prevent ischemic events, it was necessary that blood supply to the CA and SMA was maintained by placing a graft to each artery from the Y-shaped graft for replacement of AAA. Actually, only CA was sacrificed and coil embolization of CA was needed because of type 2 endoleak. The patient was discharged 17 days after surgery. A hybrid technique, endovascular repair with reconstruction of abdominal branches for TAAA and AAA, can be an alternative procedure for such high-risk operation with multiple aortic aneurysms including TAAA.

Abstract
The patient was a 60's-year-old man, who was incidentally pointed out a coin lesion in the right lung by chest radiogram. Chest computed tomography showed a round-shaped, well defined nodule of 2.5 cm in size in the right S1. Positron emission tomography did not show the accumulation of fluorodeoxyglucose in the nodule. We considered the tumor to be benign, but the patient chose surgical treatment. Partial resection of the lung was performed by thoracoscopic surgery. Histopathological diagnosis was human pulmonary dirofilariasis.

Abstract
A 71-year-old man, who had been given a diagnosis of Bochdalek hernia in infancy, was referred to our hospital for dyspnea The chest X-ray and computed tomography (CT) showed left pneumothorax with bullas and intestines in his left thoracic cavity. He was admitted to our hospital and a chest tube was inserted into the left pleural cavity. The left lung expanded immediately and air leakage was stopped. He became asymptomatic and he was discharged from the hospital on the 8th day. Most Bochdalek hernias are observed in infancy, and adult cases combined with pneumothorax and bullas are very rare.

Abstract
We report the graft replacement for surgical repair of coarctation of the aorta (CoA) in 2 men, aged 19 and 30 years old, respectively. In both patients, the pressure gradients were higher than 20 mmHg across the coarctaion by cathetherization, and higher than 30 mmHg between the upper and lower limbs. The graft replacement of the coarctated aorta was performed under cardiopulmonary bypass. Postoperatively, the pressure gradients between the upper and lower limbs dropped below 20 mmHg in both cases. Since about 50% of surgically untreated patients with this disease may be expected to die before 30 years of age, repair of CoA in adults should be performed as soon as possible.
