Abstract
BACKGROUND Vacuum phenomenon (VP) in closed pelvic fracture is a rare disorder. This study aimed to examine the prevalence and clinical findings of VP in closed pelvic fracture. METHODS We retrospectively reviewed 197 patients with closed pelvic fracture who presented to our institution from January 2012 to December 2018. Pelvic fractures were diagnosed by plain radiography and computed tomography (CT). First, we investigated the prevalence and clinical findings of VP in pelvic fractures. Second, we compared the clinical findings between pelvic fracture with and without VP. Finally, VP in pelvic fracture was evaluated clinically and radiologically. RESULTS VP in pelvic fractures was detected by CT in 9 (3.6%) of the 197 patients with pelvic fractures. Patients with VP had a significantly greater proportion of fracture progression than those without VP (42.9% vs. 11.3%, P = 0.02). Patients with VP had a greater proportion of fragility fractures of the pelvis (FFP), and a lesser proportion of bone union than those without VP, although the differences were not significant. In nine pelvic fractures with VP, all sacral fractures were classified as type 1 according to the Denis classification, and all pubic fractures were classified as type 1 according to the Nakatani classification. Two (22.2%) nonunion in nine pelvic fractures with VP occurred at the pubic fracture site alone. CONCLUSIONS Orthopedic clinicians should be aware of the potential of CT for detecting VP in pelvic fractures, especially in the course of FFP progression.

Abstract
BACKGROUND Intravenous recombinant tissue-type plasminogen activator (rt-PA) with/without endovascular treatment is sometimes not ideally effective for the treatment of acute hemodynamic stroke due to atherosclerotic major artery steno-occlusive disease, and some patients show fluctuation in or progression of symptoms despite intensive medical therapy. Urgent superficial temporal artery-middle cerebral artery (STA-MCA) bypass has been reported to be effective in patients with progressing stroke. OBJECTIVE To investigate the efficacy of urgent STA-MCA bypass performed at a single institution for progressing stroke due to hemodynamic compromise caused by atherosclerosis. METHOD We retrospectively reviewed clinical and operative records. Neurological outcomes were assessed with the modified Rankin Scale (mRS) with consideration of patient age: more than 2 points on the mRS was regarded as a poor outcome in patients under 80 years old, and more than 3 points was considered a poor outcome in those over 80 years old. The risk factors contributing to poor outcomes were evaluated. RESULTS From 2008 to 2017, 35 patients underwent urgent STA-MCA bypass for progressing stroke. The average patient age was 70.4 years (range 49-96 years). The mean National Institutes of Health Stroke Scale (NIHSS) score was 5.1 (range 0-24 points) on admission and 7.8 before surgery. After 3 months, 25 patients showed good outcomes. The preoperative NIHSS score contributed to a poor outcome (odds ratio 1.65 (95% confidence interval 1.12-2.90)). CONCLUSIONS Urgent STA-MCA bypass is a treatment option for patients with progressing stroke. The operation should be performed while the NIHSS score is low.

Treating Japanese Patients With Pembrolizumab for Platinum-Refractory Advanced Urothelial Carcinoma in Real-World Clinical Practice. J Clin Med Res 2020; 12:300-306.

Abstract
Background Since December 2017, pembrolizumab has been approved in Japan as a second-line treatment for radical unresectable urothelial carcinoma (UC) that has become exacerbated after chemotherapy by the international randomized phase 3 trial, KEYNOTE-045. The aim of this study was to evaluate the oncological efficacy and safety of pembrolizumab after failure of platinum-based chemotherapy in Japanese patients with advanced UC in real-world clinical practice. Methods A total of 34 patients who received pembrolizumab after the failure of platinum-based chemotherapy for advanced urothelial carcinoma at four institutions between January 2018 and August 2019 were retrospectively evaluated. In all patients, UC was histopathologically diagnosed, and disease progression after platinum-based chemotherapy was radiologically confirmed. Results The median follow-up period was 7.7 months. The objective response rate, median progression-free survival, and median overall survival were 20.6%, 3.3 months, and 11.7 months, respectively. Regarding the toxicities associated with pembrolizumab, adverse events (AEs) of any grade occurred in 61.8%, and grade 3 AEs occurred in 23.5%; grade ≥ 4 AEs did not occur in any patients. Univariate analyses revealed that the Eastern Cooperative Oncology Group Performance Status, neutrophil/lymphocyte ratio, liver metastases, and time from previous chemotherapy were prognostic variables. Multivariate analyses revealed that liver metastases (positive: hazard ratio, 4.23; 95% confidence interval, 1.48 - 12.08; P < 0.01) and time from previous chemotherapy (≥ 3 months: hazard ratio, 5.06; 95% confidence interval, 1.43 - 17.91; P = 0.01) were independent prognostic factors. Conclusions In this real-world clinical study, these findings concerning the efficacy and safety of pembrolizumab for advanced UC in Japanese patients were comparable to those of the open-label, international, phase 3 trial KEYNOTE-045. Liver metastases and time from previous chemotherapy were independent prognostic factors in the present study.

Composite monoclonal B-cell lymphocytosis and MYD88 L265P-positive lymphoplasmacytic lymphoma in a patient with IgM light chain amyloidosis: Case report. Pathol Int 2020; 70:458-462. [PMID: 32323419 DOI: 10.1111/pin.12937] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Revised: 03/23/2020] [Accepted: 04/06/2020] [Indexed: 11/29/2022]
Abstract
Monoclonal B-cell lymphocytosis (MBL) is an early or precursor asymptomatic proliferation of chronic lymphocytic lymphoma (CLL)-like B-cells. Lymphoplasmacytic lymphoma (LPL), often clinically associated with Waldenström macroglobulinemia, is a B-cell neoplasm characterized by frequent MYD88 L265P mutation. Here, we report a rare composite MBL and LPL in a patient with IgM light chain (AL) amyloidosis. A 74-year-old male with a known IgM monoclonal protein developed proteinuria. No lymphocytosis was detected. Renal biopsy showed deposition of AL λ amyloid in the glomeruli and vessels. Subsequent bone marrow biopsy revealed nodular atypical CLL-like small B-cell proliferation and scattered peripheral LPL. Immunohistochemistry and/or flow cytometry revealed that the atypical CLL-like population expressed CD19, CD20, CD5, weak CD23, LEF-1 and diminished surface Igκ. The LPL was positive for CD19, CD20 and surface Igλ. Using laser-capture microdissection and allele-specific polymerase chain reaction, we confirmed that MYD88 L265P was detectable in the LPL but not in the atypical CLL-like population. Thus, we demonstrated that these two populations were clonally independent, and made the diagnosis of composite MBL and LPL. An integrated clinical, pathological, immunophenotypic and genetic assessment is essential in such complicated cases, and especially 'clone-specific' MYD88 genotyping may facilitate the differential diagnoses of low-grade B-cell lymphomas.

Abstract
Cisplatin-based systemic chemotherapy is the gold-standard approach for the first-line treatment of patients with advanced or metastatic urothelial carcinoma (UC). However, the optimal number of cycles is still unclear. The current study retrospectively assessed the clinical outcome in patients who received gemcitabine and cisplatin (GC) chemotherapy as first-line treatment for metastatic urothelial cancer to clarify the timing of switching from GC therapy. A total of 61 patients with locally advanced or metastatic UC who received first-line chemotherapy with GC were retrospectively reviewed at National Hospital Organization Kyushu Cancer Center between June 2009 and August 2017. The progression-free survival (PFS) and overall survival (OS) were evaluated using the Kaplan-Meier method. The significance of associations between the clinical parameters and OS was assessed using the Cox proportional hazards regression model. The median cycle number for GC chemotherapy was 4. The median PFS and OS of all cases was 5.2 and 14.1 months, respectively. The multivariate analyses revealed that a neutrophil-to-lymphocyte ratio ≥3.0 (hazard ratio [HR], 2.521, 95% confidence interval [CI]=1.179-5.624; P=0.017) and best response to GC therapy of CR+PR (HR 0.110; 95% CI=0.028-0.411; P<0.001) were independent prognostic factors. However, the number of GC cycles (≤4 vs. >4) was not an independent prognostic factor (P=0.387). The current retrospective study indicated that changes to therapy should be considered at an early stage for cases with a therapeutic effect of SD or less, regardless of the number of GC therapy cycles.

Abstract
Photonic-crystal surface-emitting lasers (PCSELs) use the two-dimensional (2D) resonance at the band-edge of a photonic crystal for lasing, and they feature various outstanding functionalities such as high-brightness lasing, arbitrary shaping of beam patterns and on-chip 2D beam steering. In this paper, to investigate the applicability of PCSELs for high-speed operation, we design PCSELs with enhanced in-plane optical feedback, which enable single-mode lasing inside a circular region the diameter of which is less than 10 µm. To realize a strong in-plane confinement of the lasing mode, we increase the one-dimensional coupling coefficients between counter-propagating waves through the careful design of the lattice points. We also introduce an in-plane heterostructure composed of two photonic crystals with different photonic bandgaps and utilize reflection at the boundary of the two photonic crystals in addition to the optical feedback at the band-edge of each photonic crystal. By using three-dimensional finite-difference time-domain method (3D-FDTD), we confirm that the proposed hetero-PCSELs can achieve single-mode lasing operation inside a 9-µm-diameter and possibly realize a 3-dB modulation bandwidth larger than 40 GHz.

Abstract
Hemifacial spasm (HFS) is often caused by compression of the vertebral artery (VA) directly or indirectly as a result of other intervening vessels, so VA-associated HFS is difficult to treat. Recently, we have achieved good surgical outcomes using a far lateral approach and temporary clamping of V3 for VA-associated HFS. Herein, we present our method with an accompanying surgical video. From April 2018 to March 2019, 5 patients with VA-associated HFS underwent surgery, and pre-and postoperative symptoms and postoperative complications were evaluated. In the procedure, the suboccipital muscles were dissected and reflected layer by layer, and the extracranial VA (V3) was secured within the suboccipital triangle. A lateral suboccipital craniotomy followed by far lateral drilling was made to widen the surgical field from the caudolateral side. After reducing the VA flow pressure by temporary clamping of V3, the VA was transposed using a Teflon sling via two triangular space above and below the lower cranial nerves (LCNs). Causative vessels included direct VA compression in two cases and intervening vessels in three cases. The symptoms disappeared in four cases and improved satisfactorily in one case. One patient had mild hearing loss (approximately 10 dB) and hoarseness, but both improved 9 months after surgery. There was no postoperative cerebrospinal fluid leakage in any cases. A wide surgical field via the far lateral approach and the temporary clamping of V3 contributed to thorough observation of the REZ and safe and complete VA transposition.

Abstract
Daily intakes of tributyltin (TBT) and triphenyltin (TPT) compounds from meals in Shiga Prefecture, Japan, were investigated by 2 methods. Daily intakes of TBT and TPT by the duplicate portion method were, respectively, 4.7 and 0.7 μg in 1991 and 2.2 and 0.7 μg in 1992. Those by the market basket method were, respectively, 6.9 and 5.4 μg in 1991 and 6.7 and 1.3 μg in 1992. Daily intakes of TBT and TPT by the market basket method were higher than those by the duplicate portion method. These values were considerably lower than acceptable daily intakes of 80 μg/50 kg body weight specified by the Welfare Ministry of Japan for bis(tri-n-butyltin) oxide and of 25 μg/50 kg body weight specified by the Food and Agriculture Organization/ World Health Organization for TPT.

Abstract
Daily intakes of selected metals from meals in Shiga Prefecture (Japan) were investigated by the duplicate portion method and market basket method. In 1991 and 1992, daily intakes of metals by women, determined by the duplicate portion method, were, respectively, 37 and 27 μg for Cd, 4.3 and 3.5 μg for Hg, 260 and 210 μg for As, 1200 and 1200 (ig for Cu, 4700 and 3600 (ig for Mn, and 8000 and 7200 μg for Zn. Those determined by the market basket method were, respectively, 32 and 35 μg for Cd, 4.3 and 9.9 μg for Hg, 160 and 280 μg for As, 1100 and 980 μg for Cu, 3600 and 4700 μg for Mn, and 8700 and 8500 fig for Zn. No wide differences between the 2 methods were found, except for Hg data in 1992. Daily intakes of Cd and Hg in Shiga Prefecture were lower than the provisional tolerable daily intakes of 57-72 μg for Cd and 43 μg for Hg, proposed by the Food and Agricultural Organization and the World Health Organization.

Abstract
Background: Giant thrombosed vertebral artery aneurysms (GTVAs) are difficult disease to treat. Here, we are reporting a case of GTVA successfully treated with excluding the pathological segment and restoring the anterograde blood flow of the parent artery, highlighting the reliable surgical procedure. Case Description: A 55-year-old man with a left GTVA complained of right hemiparesis (manual muscle testing 4/5) represented by hand clumsiness and gait disturbance, in addition to severe left-sided dysesthesia, was referred to our hospital. The posterior inferior cerebellar artery (PICA) was incorporated into the GTVA segment, and the contralateral vertebral artery showed atherosclerotic change. Thus, we decided to treat the aneurysm with aneurysm trapping and thrombectomy, in conjunction with V3-radial artery graft (RAG)-V4 bypass and occipital artery (OA)-PICA bypass through a suboccipital transcondylar approach. The distal end of the dilated segment was meandering and deflecting outwardly to the vicinity of the internal auditory canal and was stretched in an axial direction. Thus, the V4 stump can be transposed to the triangle space made by the medulla, lower cranial nerves, and sigmoid sinus, and we could perform a safe and reliable anastomosis through the corridor. After the surgery, the compression of the brain stem was released, and right hemiparesis was improved completely after rehabilitation. The patient was discharged with a modified Rankin Scale score of 1. Conclusion: Trapping of the aneurysm and thrombectomy are the most radical treatment for GTVA, and if possible, reconstruction of anterograde blood flow with V3-RAG-V4 bypass and OA-PICA bypass is desirable.

Abstract
Background
The United Nations has defined 17 Sustainable Development Goals as a blueprint for helping ensure the health and well-being of our world by 2030. The global goals address challenges we face including poverty, inequality, climate, environmental, peace and prosperity. The goals each have targets and indicators to help measure success. Indicator #9.1.1 is defined as “Proportion of the rural population who live within 2 km of an all-season road”, which can aid in understanding multiple areas of human well-being including access to food, health care, education and in support of economic development. By understanding access to infrastructure, we can focus on affordable and equitable access for all. We focused on the Shikoku Island of Japan and calculated indicator #9.1.1 using spatial analysis.
Methods
We utilized data from three sources listed below. Cho-cho-moku boundaries population data from the Esri Japan corporation. Metropolitan Employment Area data from the Center for Spatial Information Science at the University of Tokyo. Emergency transport road data from the MLIT of Japan. We conducted proximity analysis with Geographic Information System (GIS) and estimated population of the target area using the area ratio of the target area to the original Cho-cho-moku area.
Results
The percentage of the rural population who live within 2 km of an all-season road is 79.5% and those who have no access to an all-season road in the Shikoku Island is 20.5%.
Conclusions
We found the proportion of the rural population that cannot reach an all-season road by calculating indicator #9.1.1. 20.5% of the rural population in the Shikoku Island of Japan may have difficulties accessing essential services such as health care, education, food, and may have difficulties with economic development. By understanding accessibility to road infrastructure, we were able to identify areas at risk for access. We can work towards creating more equitable access in a next step.
Key messages
By conducting spatial analysis with GIS, we can identify areas at risk for access to infrastructure. we can focus on creating more affordable and equitable access for all by understanding access to infrastructure such as health care, education and food.

Abstract
Background: Very large and giant aneurysms (≥20 mm) of the internal carotid artery (ICA) bifurcation (ICAbif) are definitely rare, and optimal treatment is not established. Endovascular treatments are reported as suboptimal due to difficulties of complete occlusion and tendencies to recanalization. Therefore, direct surgery remains an effective strategy if the clipping can be performed safely and reliably, although very difficult. Case Description: Two cases of ICAbif aneurysms (>20 mm) were treated. Prior assistant superficial temporal artery (STA)-middle cerebral artery (MCA) bypass was performed to avoid ischemic complications during prolonged temporary occlusion of the arteries in both cases. In Case 1 (22-mm aneurysm), the dome was inadvertently torn in applying the clip because trapping had resulted in insufficient decompression. Therefore, in Case 2 (28-mm aneurysm), almost complete trapping of the aneurysm and subsequent dome puncture was performed, and the aneurysm was totally deflated by suction from the incision. This complete aneurysm decompression allowed safe dissection and successful clipping. Conclusion: Trapping, deliberate aneurysm dome puncture, and suction decompression from the incision in conjunction with assistant STA-MCA bypass can achieve complete aneurysm deflation, and these techniques enable safe dissection of the aneurysm and direct clipping of the aneurysm neck. Direct clipping with this technique for very large and giant ICAbif aneurysms may be the optimal treatment choice with the acceptable outcome if endovascular treatment remains suboptimal.

Abstract
Identifying the two-dimensional (2D) topological insulating (TI) state in new materials and its control are crucial aspects towards the development of voltage-controlled spintronic devices with low-power dissipation. Members of the 2D transition metal dichalcogenides have been recently predicted and experimentally reported as a new class of 2D TI materials, but in most cases edge conduction seems fragile and limited to the monolayer phase fabricated on specified substrates. Here, we realize the controlled patterning of the 1T^{'} phase embedded into the 2H phase of thin semiconducting molybdenum-disulfide by laser beam irradiation. Integer fractions of the quantum of resistance, the dependence on laser-irradiation conditions, magnetic field, and temperature, as well as the bulk gap observation by scanning tunneling spectroscopy and theoretical calculations indicate the presence of the quantum spin Hall phase in our patterned 1T^{'} phases.

Relapse of aseptic meningitis induced by ipilimumab and nivolumab therapy for metastatic renal cell carcinoma: A case report. Mol Clin Oncol 2019; 11:590-594.

Abstract
The combined immunotherapy of nivolumab and ipilimumab causes a variety of autoimmune-related adverse events (irAEs). The current report details a 70-year-old woman with clear cell renal cell carcinoma metastasis in the lung. Two weeks after two courses of treatment, the patient complained of headache, dizziness and nausea. Cerebrospinal fluid (CSF) analysis revealed an elevated protein level of 195 mg/dl and a significantly elevated white blood cell (WBC) count of 830/mm3 (lymphocytes, 825/mm3; neutrophils, 5/mm3). The results excluded malignancy and infection. The patient was diagnosed with aseptic meningitis and was administered intravenous prednisolone (1 mg/kg/day). On the 49th day of the 2nd course of treatment, no recurrence of clinical symptoms was exhibited during maintenance oral steroid treatment (prednisolone 10 mg/day) and CSF analysis revealed that the WBC count had dropped to 44/mm3 (lymphocytes only). Therefore, the 3rd course of treatment was readministered the next day. After two weeks, the patients again complained of nausea, anorexia and fatigue. CSF analysis demonstrated that the WBC count was not increased from the result obtained previously. However, brain MRI scans revealed the mild diffuse enlargement of the pituitary and endocrine system tests revealed reduced adrenocorticotropic hormone (ACTH; 2.0 pg/ml) and cortisol (1.12 µg/dl) levels. The patient was diagnosed with isolated ACTH deficiency and oral hydrocortisone was administered after prednisolone cessation. On the 25th day of the 3rd course of treatment, the patient complained of headache and anorexia. CSF examination revealed that the WBC count had increased a second time (53/mm3; lymphocytes only) and laboratory data revealed hepatic dysfunction. The patient was then diagnosed with relapse of aseptic meningitis and liver dysfunction. While continuing oral hydrocortisone treatment, the administration of intravenous prednisolone was started. The observed liver dysfunction and aseptic meningitis gradually improved. The current report may be useful for avoiding delays in the diagnosis and treatment of this life-threatening and uncommon irAE, in which CSF examinations are useful for diagnosis and management.

Abstract
Abstract
Background
The relation between very low on-treatment low-density lipoprotein cholesterol (LDL-C) level and the cardiovascular event risk is still unclear in patients receiving the same doses of statins.
Methods
From the REAL-CAD study comparing high-dose with low-dose pitavastatin therapy in Japanese patients with stable coronary artery disease, 11105 patients without reported non-adherence for the study drug were divided into 3 groups according to the on-treatment LDL-C level at 6-month (<70 mg/dL, 70–100 mg/dL, and ≥100 mg/dL; N=1016, N=3078, and N=1665 in the pitavastatin 1 mg/day stratum; N=2431, N=2524, and N=391 in the pitavastatin 4 mg/day stratum). Primary outcome measure was a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal ischemic stroke, or unstable angina requiring emergent admission.
Results
In the pitavastatin 1 mg/day stratum, cumulative 4-year incidence of the primary outcome measure was not significantly different across the 3 groups (5.0%, 5.7%, and 5.2%, P=0.51), while in the 4 mg/day stratum, it was significantly higher in the LDL-C ≥100 mg/dL group than in other groups (4.5%, 3.4%, and 9.1%, P<0.001). The adjusted risks of the LDL-C <70 mg/dL group relative to the LDL-C 70–100 mg/dL group (reference) remained insignificant for the primary outcome measure in both 1 mg/day and 4 mg/day strata (HR 0.84, 95% CI 0.58–1.18, P=0.32, and HR 1.25, 95% CI 0.88–1.79, P=0.22). The adjusted risk of LDL-C ≥100 mg/dL group relative to the reference group was not significant for the primary outcome measure in the 1 mg/day stratum (HR 0.82, 95% CI 0.60–1.11, P=0.21), while it was highly significant in the 4 mg/day stratum (HR 3.32, 95% CI 2.08–5.17, P<0.001). In the on-treatment LDL-C ≥100 mg/dL group in the 4 mg/day stratum, LDL-C increased by 6.3 mg/dL from baseline to 6-month despite dose escalation of pitavastatin from 1 mg/day to 4 mg/day, suggesting the presence of unreported poor adherence in this small subgroup.
Adjusted Effects of On-treatment LDL-C
Conclusions
Very low on-treatment LDL-C level (<70 mg/dL) was not associated with lower cardiovascular event risk compared with moderately low on-treatment LDL-C level (70–100 mg/dL) in patients receiving the same doses of statins. Too much emphasis on the target LDL-C strategy might mislead the clinical practice.
