Abstract
BACKGROUND The importance of a wider circumferential isolation of the pulmonary veins (PV), which includes a large portion of the left atrial posterior wall (LAPW), has been suggested in several studies. However, the extended isolation area using a larger inflated visually guided laser balloon (VGLB) ablation remains to be elucidated. METHODS Seventy-eight patients with atrial fibrillation (AF) who underwent VGLB ablation were enrolled in this prospective study. An electroanatomic map of the left atrium was obtained before and after PV isolation (PVI) using a conventional-sized VGLB. The isolation areas were extended by the largest-sized VGLB ablation and remapped in the same manner. After the ablation, isolation areas were calculated with CARTO-3 system. The one-year atrial arrhythmia (Ata) recurrence was assessed. RESULTS: The largest-sized VGLB ablation yielded statistically greater areas of isolation in left-sided PV antrum (PVA) (11.5 ± 2.3 cm2 vs. 15.9 ± 3.5 cm2, P < .001) and right-sided PVA (14.2 ± 3.3 cm2 vs. 20.6 ± 4.4 cm2, P < .001) than the conventional-sized VGLB. Further, non-ablated LAPW (12.3 ± 4.4 cm2 vs. 7.8 ± 3.9 cm2, P < .001) was significantly reduced after largest-sized VGLB ablation, compared to the conventional-sized VGLB ablation. The one-year Ata freedom was 83.7% in patients with paroxysmal AF and 96.4% in those with persistent AF. CONCLUSION The largest-sized VGLB ablation technique can create a significantly wider isolation area of PVA and debulk a large amount of LAPW than the conventional-sized VGLB ablation. The one-year outcome was similarly high in paroxysmal and persistent AF.

Abstract
Balloon-based catheter ablation including visually guided laser balloon (VGLB) has been adopted a first line therapeutic strategy for the patients with atrial fibrillation (AF). Recently, the roof area ablation beyond pulmonary vein (PV) isolation (PVI) using cryoballoon has been described as an effective therapy for the patients with persistent AF. However, the roof area ablation performed with a VGLB remains unknown. In this case, we report the case of roof area ablation for the patient with persistent AF using a VGLB.

Abstract
CASE 1 A male in his 60s underwent a right transperitoneal laparoscopic partial nephrectomy procedure for a right renal tumor. Rupture of a renal cyst located close to the tumor occurred intraoperatively. The histopathological diagnosis was clear cell renal cell carcinoma (CCRCC), pT1aN0M0, G2, v0, with negative resection margins. At 84 months after surgery, computed tomography (CT) revealed a 10 mm mass in the rectus abdominis muscle at the camera port site used for the partial nephrectomy. An open lumpectomy was then performed and the histopathological diagnosis was CCRCC. One year later, a 40 mm sized mass was detected in the mesentery of the small intestine by CT, which was removed laparoscopically with part of the mesentery and diagnosed as CCRCC. Since that surgery, the patient has been free from recurrence for 8 years. CASE 2 A male in his 60s underwent a left retroperitoneal laparoscopic nephrectomy procedure for a left renal tumor. The histopathological diagnosis was CCRCC, pT1aN0M0, G1, v0, with negative resection margins. At 31 months after surgery, CT revealed a 32 mm mass in the retroperitoneal cavity at the right hand port site used for the laparoscopic nephrectomy. The mass was removed with part of the twelfth rib and erector spinae muscles in a lump, and the histopathological diagnosis was CCRCC. Since that surgery, the patient has been free from recurrence for 19 months. For the treatment of solitary port site recurrence of renal cell carcinoma after a laparoscopic radical/partial nephrectomy, we recommend surgical resection for a good prognosis.

Abstract
Objectives Despite the prognostic impacts of preoperative fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography examination, fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography-based prognosis prediction has not been used clinically because of the disparity in data between institutions. By applying an image-based harmonized approach, we evaluated the prognostic roles of fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography parameters in clinical stage I non-small cell lung cancer. Methods We retrospectively examined 495 patients with clinical stage I non-small cell lung cancer who underwent fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography examinations before pulmonary resection between 2013 and 2014 at 4 institutions. Three different harmonization techniques were applied, and an image-based harmonization, which showed the best-fit results, was used in the further analyses to evaluate the prognostic roles of fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography parameters. Results Cutoff values of image-based harmonized fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography parameters, maximum standardized uptake, metabolic tumor volume, and total lesion glycolysis were determined using receiver operating characteristic curves that distinguish pathologic high invasiveness of tumors. Among these parameters, only the maximum standardized uptake was an independent prognostic factor in recurrence-free and overall survivals in univariate and multivariate analyses. High image-based maximum standardized uptake value was associated with squamous histology or lung adenocarcinomas with higher pathologic grades. In subgroup analyses defined by ground-glass opacity status and histology or by clinical stages, the prognostic impact of image-based maximum standardized uptake value was always the highest compared with other fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography parameters. Conclusions The image-based fluorine-18 fluorodeoxyglucose-positron emission tomography/computed tomography harmonization was the best fit, and the image-based maximum standardized uptake was the most important prognostic marker in all patients and in subgroups defined by ground-glass opacity status and histology in surgically resected clinical stage I non-small cell lung cancers.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is reported to produce anti-HLA antibodies. We report a case of chronic active antibody-mediated rejection caused by pre-existing donor-specific antibody (DSA) in a patient with SLE without a history of sensitization. CASE REPORT The case was a 29-year-old man with end-stage renal disease due to lupus nephritis. Cross-match with the mother was negative, but low titer anti-DQ DSA was detected, although he had no prior history of sensitization. After desensitization with rituximab and mycophenolate mofetil, a living donor kidney transplant was undergone, and his early postoperative period was uneventful. However, his renal function started to decline at 2 years post-transplant. Although there was no rejection on the biopsy at 2.5 years post-transplant, his renal function continued to decline after that. At 7 years, he had failed his graft due to chronic active antibody-mediated rejection. Retrospective analysis of human leukocyte antigen antibody tests revealed that anti-DQ DSA had disappeared at 1 year post-transplant, but high titer DSA was detected again with complement-binding capacity at 2 years and after that. CONCLUSION Careful monitoring might be warranted in an SLE patient with pre-existing DSA, even though the titer was low and without any prior histories of sensitization events.

Abstract
AbstractBalloon ablation therapy has recently been used for atrial fibrillation (AF) ablation. Laser balloons possess the property in which the balloon size can be changed. Standard laser balloon ablation (Standard LBA) was followed by additional ablation using a maximally extended balloon (Extended LBA) and its lesion characteristics were compared to cryoballoon ablation (CBA), another balloon technology. From June 2020 to July 2021, patients with paroxysmal AF who underwent an initial pulmonary vein (PV) isolation were enrolled. Sixty-five patients with paroxysmal AF were included, 32 in the LBA and 33 in the CBA group. To measure the isolated surface area after the ablation procedures, left atrial voltage mapping was performed after Standard LBA, Extended LBA, and CBA. The baseline patient characteristics did not differ between LBA and CBA. Extended LBA could successfully increase the isolated area more than Standard LBA for all four PVs. Compared to CBA, the isolated area of both superior PVs was significantly greater with Extended LBA (left superior PV: 8.5 ± 2.1 vs 7.3 ± 2.4, p = 0.04, right superior PV: 11.4 ± 3.7 vs 8.7 ± 2.7, p < 0.01), and thus the non-isolated posterior wall (PW) was smaller (8.5 ± 3.4 vs 12.4 ± 3.3, p < 0.01). Nevertheless, changes in the cardiac injury markers were significantly lower with LBA than CBA. There was no significant correlation between the cardiac injury level and isolated area in both groups. In conclusion, Extended LBA exhibited a significantly greater isolation of both superior PVs and resulted in a smaller non-isolated PW, but the cardiac injury markers were significantly suppressed as compared to CBA.

Abstract
A 60-year-old man visited our hospital to treat a large cystic mass in the pelvis which had been found by abdominal ultrasonography in December 201X. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a multilocular cyst with a maximum diameter of about 10 cm. CT-guided drainage and sclerotherapy with minocycline reduced the size of tumor by 40%, but symptoms such as difficulty of defecation and urinary frequency appeared a year and a half later due to re-enlargement of the cysts. Laparoscopic resection of the multilocular cysts was performed, and all cysts were removed almost completely using transrectal ultrasonography. The multilocular cyst was positive for NKX3.1 by immunohistochemical staining, and was diagnosed as a giant multilocular prostatic cystadenoma. After surgery, the symptoms such as difficulty of defecation and urinary frequency were relieved promptly. One year after the surgery, the patient was free from recurrence of the disease.

Abstract
Inflammatory myofibroblastic tumor (IMT) of the urinary bladder is a rare soft tissue tumor characterized by spindle cell proliferation with inflammatory cell infiltration. We present a case of bladder IMT occurring in a 6-year-old boy. Pretreatment CT images depicted a polypoid and broad-based mass measuring 18 mm in the superior to the front wall of the bladder, and the mass showed isodensity on precontrast image and ring enhancement of the mass after the intravenous administration of contrast material. Pelvic MRI demonstrated the 18 × 17 × 16 mm broad-based mass, suggesting submucosal tumor in the dome of the bladder. The mass showed low-to-moderate signal intensity on T1-weighted images and slight high signal intensity on T2-weighted images and restricted diffusion with low signal intensity on ADC map and abnormal high signal intensity on DWI. Transurethral resection of the bladder tumor and partial cystectomy were undertaken, and the pathology revealed IMT of the bladder. We suggest its inclusion in the differential diagnosis of cases of a polypoid and broad-based mass on the superior wall or the front wall of the bladder with ring enhancement on contrast-enhanced CT and MRI.

Abstract
Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the human gastrointestinal tract. Small intestinal GISTs appear to be associated with poorer prognosis and higher metastasis rate than gastric GISTs of the same size and mitotic index. Recently, we reported that cell adhesion molecule 1 (CADM1) is expressed specifically in most small intestinal GISTs, but not in most gastric GISTs, suggesting that this difference in CADM1 expression between gastric GISTs and small intestinal GISTs might influence the difference in clinical behavior between them. The aim of the present study was to examine whether high CADM1 expression affected proliferation, migration, invasion, adhesion to endothelial cells and transendothelial migration of cultured GIST cells by comparing original GIST-T1 cells with very low CADM1 expression with GIST-T1 cells with high CADM1 expression induced by CADM1 cDNA transfection (GIST-T1-CAD cells). GIST-T1-CAD cells had reduced ability to proliferate, migrate and invade compared with the original GIST-T1 cells, but showed significantly higher ability to adhere to human umbilical vein endothelial cells and migrate through endothelial cell monolayers. Thus, CADM1 may contribute to higher metastasis rates in small intestinal GISTs facilitating tumor cell adhesion to vascular endothelial cell and transendothelial migration of tumor cells. CADM1 might serve as a potential target for inhibition of metastasis in small intestinal GISTs.

Abstract
Objective: Cardiac arrest (CA) has been observed in some patients with
Takotsubo syndrome (TTS), most of whom had CA at the initial presentation of TTS. The
objective of this report was to discuss the factors underlying the onset of this
syndrome. Case presentation: A 72-year-old woman with refractory antineutrophil
cytoplasmic autoantibody-associated lung disease was referred to our hospital. Twenty
minutes after bronchoscopic examination, cardiopulmonary arrest suddenly occurred.
Resuscitation immediately resumed her heartbeat and spontaneous breathing. Subsequent
12-lead electrocardiography, echocardiography, and left ventricular angiography revealed
TTS. Conclusion: This case indicates that bronchoscopy can cause severe TTS,
especially in patients with systemic inflammation.

Abstract
Multiple-system atrophy is an adult-onset progressive neurodegenerative disease affecting the central nervous system, including the spinal cord. There has been no perioperative guideline of the muscle relaxants used in multiple-system atrophy, although a recent article recommends anesthesiologists to use shorter-acting drugs at the lowest possible doses in the patients. Here, we document the first case with multiple-system atrophy undergoing surgery managed with a combination of rocuronium and sugammadex. The recovery time to the train-of-four count 2 after intravenous rocuronium 0.6 mg / kg, or the time from the start of sugammadex 2 mg / kg intravenously to the train-of-four ratio over 0.9 was prolonged in our case more than 20 and 2 minutes compared with those in healthy subjects, respectively. Neuromuscular monitoring, in addition to the careful vigilance in the perioperative period, seems mandatory in the patients. J. Med. Invest. 68 : 381-382, August, 2021.

Abstract
Ductal adenocarcinoma is a variant of prostatic adenocarcinoma, originating from the epithelial lining of the primary and secondary ducts of the prostate. We report a 63-year-old male with prostatic ductal adenocarcinoma, presenting as urinary retention and a prostate-specific antigen (PSA) level of 11.71 ng/mL and biopsy-proven prostate cancer (Gleason score 3 + 3). MRI showed 2 hemorrhagic, multilocular cysts projecting into the bladder side from the prostatic inner gland and between the prostate and the right seminal vesicle. The prostate inner gland showed high signal intensity on the T2-weighted image and included tiny hyperintense spots on the fat-suppression T1-weighted image. In the part of the border of the hemorrhagic, multilocular cyst, a solid portion showing slight low intensity on T1-weigthed imaging and markedly restricted diffusion was observed, suggesting prostate cancer. He underwent total prostatectomy, and ductal adenocarcinoma (Gleason score 4 + 4) in the prostate inner gland and multilocular cysts was pathologically diagnosed. After the operation, his PSA level gradually increased, and MRI 8 months after the operation showed a vesical multilocular cyst, suggesting local recurrence. After he underwent radiation therapy and hormonal therapy, PSA level decreased, and no re-recurrence was observed during 8 years. We suggest its inclusion in the differential diagnosis of cases of prostatic ductal adenocarcinoma's multiloculated cystic formation around the prostate and the bladder.

Abstract
BACKGROUND Ectopic pancreas is basically a benign disease and is not always necessary to be removed. However, all types of neoplasms occurring in the normal pancreas such as ductal adenocarcinomas and intraductal papillary mucinous neoplasms (IPMNs) may develop even within ectopic pancreas. We recently encountered an extremely rare case of ectopic pancreas in the gastric antrum associated with IPMN possessing a GNAS mutation. CASE PRESENTATION A 71-year-old Japanese woman complained of epigastric pain. Computed tomography and upper gastrointestinal endoscopy showed an intramural cystic mass in the antrum of the stomach. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) biopsy did not give a definitive diagnosis, and the patient underwent resection of the lesion. Histology of the resected specimen showed that the gastric intramural lesion was ectopic pancreas. Moreover, the lesion contained dilated duct components with tubulo-villous epithelial proliferation consistent with pancreatic IPMN. Since the covering epithelial cells had highly atypical nuclei, the lesion was diagnosed as IPMN with high grade dysplasia. Immunohistochemistry showed that the IPMN component showed to be MUC2-, MUC5AC-, and CDX2-positive but MUC1- and MUC6-negative. Mutational analyses using genomic DNA revealed that the IPMN component had a mutation of GNAS at exon 8 (Arg201Cys). CONCLUSION We finally diagnosed this case as gastric ectopic pancreas accompanied by intestinal type IPMN with high grade dysplasia possessing GNAS mutation. Although there were 17 cases of ectopic pancreas with IPMN including 6 cases of gastric ones reported in the English literature, this is the first case of ectopic pancreas with IPMN which was proved to have GNAS mutation. Intimate preoperative examinations including imaging analyses and EUS-FNA biopsy/cytology are recommended to decide whether the lesion has to be resected or not even if they are not effective for getting the right diagnosis.

Abstract
Treatment-related neuroendocrine-differentiated prostate cancer (NEPC) is a rare tumor entity that transdifferentiates from adenocarcinoma as an adaptive response to androgen receptor pathway inhibition. We report a 79-year-old male with treatment-related NEPC, presenting as rectal bleeding after hormonal therapy. MRI showed a 51 × 52 × 65 mm tumor occupying almost the whole prostate gland and invading the seminal vesicle and rectum as moderately heterogeneous hypointensity on T2-weighted image, restricted diffusion on apparent diffusion coefficient map and diffusion-weighted imaging, and heterogeneous enhancement on Gd-enhanced T1-weighted image. FDG-PET/CT showed strong FDG uptake of the prostate tumor, and somatostatin receptor scintigraphy (SRS) showed mild uptake of the prostate tumor. The surgically resected specimen revealed NEPC. If prostate cancer worsens despite conventional therapy, treatment-related NEPC should be considered, and the benefit of imaging examinations including prostate MRI, FDG-PET/CT, and SRS is in localizing lesions with neuroendocrine differentiation.

Abstract
The occurrence of cryptic species within a threatened taxon is rare, but where they do occur, understanding species boundaries is essential for planning an effective conservation strategy. The short-tailed albatross Phoebastria albatrus is a Vulnerable seabird that mainly breeds on Torishima and the Senkaku Islands in the western North Pacific. Although it has been tacitly regarded as a single management unit with 2 breeding sites, the species is known to comprise 2 genetically separated populations (Senkaku-type and Torishima-type). However, morphological examination of birds from both populations has not been conducted owing to the difficulty in accessing the Senkaku Islands. In this study, we examined the morphological differences between immigrants from the Senkaku Islands to Torishima (Senkaku-type) and native birds on Torishima (Torishima-type) and found significant differences in morphological characteristics between the 2 bird types. In general, Torishima-type birds were larger than Senkaku-type birds, whereas Senkaku-type birds had relatively longer beaks. Based on the morphological differences found in this study as well as genetic and ecological differences revealed in previous studies, we believe that Senkaku- and Torishima-type birds should be classified as different cryptic species. To the best of our knowledge, this is the first case of cryptic species being identified in a threatened avian species.

Abstract
Abstract
Background
The visually guided laser balloon ablation is a balloon-based catheter ablation technology used for atrial fibrillation (AF) ablation in recent years. This balloon catheter consists of a compliant balloon that has the capability of real-time endoscopic visualization of the targeted pulmonary vein (PV). The sizeable balloon is usually inflated to obtain optimal PV occlusion. The isolation area after laser balloon (LB) ablation was reported to be smaller than that after cryoballoon ablation. However, when LB is inflated with its maximum pressure, it can visualize wide-area PV antrum. Thereby, we suspected that larger-size LB can create wider isolation area.
Purpose
The aim of this study is to quantitatively evaluate the isolation area after LB ablation at the size larger than appropriate size for ablation in the pulmonary vein carina region.
Methods
We assessed 66 patients with AF who underwent LB ablation at the larger inflation size in our hospital during the period from July 2018 to July 2019. After LB ablation, we created voltage maps with a circular mapping catheter and calculated isolation areas with CARTO system.
Results
Figure shows a larger LB with its maximum pressure. PV antrum isolation was extended to the posterior wall in all patients. The left- and right-sided pulmonary vein antrum isolation area were 15.1±3.9 and 19.4±4.3 cm2, respectively.
Conclusion
LB at the larger inflation size with its maximum pressure can isolate wider-area circumferential PV antrum than previously reported. This method may be a new way of pulmonary vein antrum isolation.

Abstract
Inwardly rectifying potassium (Kir) channels play key roles in functions, including maintaining the resting membrane potential and regulating the action potential duration in excitable cells. Using in situ whole-cell recordings, we investigated Kir currents in mouse fungiform taste bud cells (TBCs) and immunologically identified the cell types (type I-III) expressing these currents. We demonstrated that Kir currents occur in a cell-type-independent manner. The activation potentials we measured were -80 to -90 mV, and the magnitude of the currents increased as the membrane potentials decreased, irrespective of the cell types. The maximum current densities at -120 mV showed no significant differences among cell types (p>0.05, one-way ANOVA). The density of Kir currents was not correlated with the density of either transient inward currents or outwardly rectifying currents, although there was significant correlation between transient inward and outwardly rectifying current densities (p<0.05, test for no correlation). RT-PCR studies employing total RNA extracted from peeled lingual epithelia detected mRNAs for Kir1, Kir2, Kir4, Kir6, and Kir7 families. These findings indicate that TBCs express several types of Kir channels functionally, which may contribute to regulation of the resting membrane potential and signal transduction of taste.

Abstract
A 66-year-old Japanese woman was admitted to our hospital for jaundice. Abdominal computed tomography(CT) showed dilatation of the intra- and extra-hepatic bile duct, and a hypovascular lesion measuring 30mm in diameter in the head of the pancreas. This tumor was in contact with the(superior mesenteric vein: SMV)and(inferior vena cava: IVC), but there were no obvious signs of invasion. Upper gastrointestinal endoscopy showed obstruction of the duodenum. We chose to perform an upfront surgery, considering the patient's general condition being stable and the difficulties associated with endoscopic biliary drainage. During surgery, stiff attachment between the tumor and IVC was identified and wedge resection of the IVC wall was performed. SMV resection and end-to-end reconstruction were also carried out. Pathological studies of the surgical specimen revealed direct invasion by the pancreatic adenocarcinoma into the adventitia of the IVC. The postoperative course was uneventful, and the patient was discharged from the hospital on the 27th postoperative day; she underwent adjuvant chemotherapy(S-1 100mg/day)and is still alive without tumor recurrence, 21 months after surgery. Cases of resected pancreatic adenocarcinoma directly invading the IVC are rare. In this case, pancreaticoduodenectomy along with wedge resection of the IVC wall could safely be performed, and no complications were observed. There is a need for further accumulation of similar cases.

Abstract
Autoimmune hemolytic anemia (AIHA) is a rare comorbidity in colorectal cancer (CRC) and has an unknown etiology. Previously, we described an AIHA case secondary to CRC with ectopic band 3 expression. Herein, we investigated ectopic band 3 expression and erythrocyte membrane-bound IgG in a CRC cohort. Between September 2016 and August 2018, 50 patients with CRC and 26 healthy controls were enrolled in the present study. The expression of band 3 and SLC4A1 mRNA was observed in 97% of CRC surgical specimens. Although clinical AIHA was not observed in any patient with CRC, a direct antiglobulin test was positive in 10 of the patients in the CRC group (p = 0.01). Flow cytometry revealed significantly increased erythrocyte membrane-bound IgG among patients with CRC compared to healthy controls (mean ± standard deviation; 38.8 ± 4.7 vs. 29.9 ± 15.6, p = 0.012). Normocytic anemia was observed, including in cases negative for fecal occult blood, suggesting a shortened erythrocyte life-span due to increased membrane-bound IgG. Immunoprecipitation revealed increased anti-band 3 autoantibodies in patients' sera. Mouse experiments recapitulated this phenomenon. We also confirmed that band 3 expression is controlled by 5'AMP-activated protein kinase under hypoxic conditions. These findings increase our understanding of the etiology of cancer-related anemia.

Abstract
Recipients of organ transplants are immunosuppressed and at high risk of oral infection. Oral diseases are often neglected compared with infections of other organs that typically confer higher morbidity. However, severe local symptoms hinder oral intake, decrease quality of life, and are sometimes lethal. Here we describe a case of a 57-year-old woman who developed recurrent aphthous stomatitis after kidney transplantation; the cause of the infection was complex and included cytomegalovirus, herpes simplex virus, and Candida species. Since misdiagnosis of oral diseases impairs patient quality of life and increases morbidity, clinicians should be aware of possible etiologies of oral infections in renal transplant recipients.

Abstract
AIMS The aim of this study was to report the long-term results of rotational acetabular osteotomy (RAO) for symptomatic hip dysplasia in patients aged younger than 21 years at the time of surgery. PATIENTS AND METHODS We evaluated 31 patients (37 hips) aged younger than 21 years at the time of surgery retrospectively. There were 29 female and two male patients. Their mean age at the time of surgery was 17.4 years (12 to 21). The mean follow-up was 17.9 years (7 to 30). The RAO was combined with a varus or valgus femoral osteotomy or a greater trochanteric displacement in eight hips, as instability or congruence of the hip could not be corrected adequately using RAO alone. RESULTS The mean Merle d'Aubigné clinical score improved significantly from 15.4 to 17.2 (p < 0.0001). The mean centre-edge (CE) angle improved from -2.6° to 26°, the mean acetabular roof angle improved from 3.0° to 5.2°, and the mean head lateralization index improved from 0.68 to 0.62. Progression of radiological osteoarthritis (OA) was seen in seven hips, but no patient underwent total hip arthroplasty. CONCLUSION RAO is an effective form of correction for a severely dysplastic hip in adolescent and young adult patients. Cite this article: Bone Joint J 2019;101-B:390-395.

Abstract
BACKGROUND High-resolution esophageal manometry (HREM) has become a leading tool in the assessment of esophageal motor disorders, replacing conventional manometry. However, there is limited data about the contribution of HREM as compared with conventional manometry to the assessment of esophageal motor disorders in patients with non-cardiac chest pain (NCCP). The aim of the study was to compare the distribution of esophageal motor disorders in patients with NCCP using HREM as compared with conventional manometry and to determine if HREM improved diagnosis of these disorders. METHODS In this study, we included 300 consecutive patients with NCCP who underwent either HREM or conventional manometry over a period of 10 years. A total of 150 patients had conventional manometry and the other 150 patients HREM. The Chicago 3.0 classification and the Castell and Spechler classification were used to determine the esophageal motor disorder of NCCP patients undergoing HREM and conventional manometry, respectively. KEY RESULTS In both HREM and the conventional manometry groups, normal esophageal motility was the most frequent finding (47% and 36%; respectively, P = .054). Hypotensive lower esophageal sphincter was the most common motility disorder identified by conventional manometry (27.3%), while ineffective esophageal motility was the most common esophageal motor disorder identified by HREM (25.3%). CONCLUSIONS & INFERENCES There is a discrepancy in the type of esophageal motor disorders identified by HREM as compared with conventional manometry in NCCP patients. Hypotensive motility disorders are the most commonly diagnosed by both manometric techniques.

Abstract
The ATP-dependent bacterial protein disaggregation machine, ClpB belonging to the AAA+ superfamily, refolds toxic protein aggregates into the native state in cooperation with the cognate Hsp70 partner. The ring-shaped hexamers of ClpB unfold and thread its protein substrate through the central pore. However, their function-related structural dynamics has remained elusive. Here we directly visualize ClpB using high-speed atomic force microscopy (HS-AFM) to gain a mechanistic insight into its disaggregation function. The HS-AFM movies demonstrate massive conformational changes of the hexameric ring during ATP hydrolysis, from a round ring to a spiral and even to a pair of twisted half-spirals. HS-AFM observations of Walker-motif mutants unveil crucial roles of ATP binding and hydrolysis in the oligomer formation and structural dynamics. Furthermore, repressed and hyperactive mutations result in significantly different oligomeric forms. These results provide a comprehensive view for the ATP-driven oligomeric-state transitions that enable ClpB to disentangle protein aggregates. The bacterial protein disaggregation machine ClpB uses ATP to generate mechanical force to unfold and thread its protein substrates. Here authors visualize the ClpB ring using high-speed atomic force microscopy and capture conformational changes of the hexameric ring during the ATPase reaction.

Abstract
Radiological findings of pulmonary infarction have been well characterized mainly in established infarction. However, the early course CT appearance of patients who develop pulmonary infarction has not yet been fully elucidated. A 50-year-old female with a history of postmenopausal hormone replacement therapy (HRT) presented with dry cough and high-resolution computed tomography (HRCT) findings of fan-shaped segmental ground-glass opacity (GGO) in the right lower lobe. As the parenchymal density in the GGO gradually enlarged over a period of 4 weeks in spite of antibiotic treatment, the patient was referred to our hospital on clinical suspicion of bronchioloalveolar cell carcinoma. However, the pathological findings of a transbronchial biopsy of the lesion were compatible with pulmonary infarction. After an endoscopic examination, the typical CT appearance of established pulmonary infarction was observed. Moreover, enhanced CT detected an intraluminal filling defect in the right lower lobe artery suggesting peripheral pulmonary emboli. Our case was a peripheral pulmonary infarction probably induced by HRT, and suggested that fan-shaped GGO may be a premonitory sign of pulmonary infarction.

Abstract
BACKGROUND AND OBJECTIVES To explore whether lymphocytes in sentinel lymph nodes (SLNs) are highly exposed to tumor neoantigens and thus express high level of programmed death 1 (PD-1), we examined PD-1 expression in SLNs and non-sentinel regional lymph nodes (non-SLNs) in breast cancer. METHODS We performed PD-1 immunohistochemistry in two cohorts: 40 metastasis-negative SLNs including 10 patients for each subtype (luminal A-like, luminal B-like, HER2, and triple negative breast cancer [TNBC]); and 25 pairs of metastasis-positive SLNs and non-SLNs (10 luminal A-like, 10 luminal B-like, and 5 TNBC). RESULTS Among 40 metastasis-negative SLNs, 34 and 6 samples were PD-1 intensity grade 1 (low) and 2 (high), respectively. PD-1 intensity correlated with PD-1-positive lymphocyte numbers (P = 0.005); TNBC had the highest PD-1 lymphocyte numbers among all subtypes. The median PD-1-positive lymphocyte number was higher in SLNs than non-SLNs. In most cases, more lymphocytes in SLNs expressed PD-1 than those in non-SLNs (P < 0.0001). CONCLUSIONS TNBC had the greatest PD-1 expression among all subtypes, and metastasis-positive SLNs had more PD-1-positive lymphocytes than downstream non-SLNs. These data suggested that lymphocytes in SLNs are activated following exposure to tumor neoantigens and thus tumor specific, and could be utilized as a biomarker platform.

Abstract
Aims Our aim was to evaluate the radiographic characteristics of patients undergoing total hip arthroplasty (THA) for the potential of posterior bony impingement using CT simulations. Patients and Methods Virtual CT data from 112 patients who underwent THA were analysed. There were 40 men and 72 women. Their mean age was 59.1 years (41 to 76). Associations between radiographic characteristics and posterior bony impingement and the range of external rotation of the hip were evaluated. In addition, we investigated the effects of pelvic tilt and the neck/shaft angle and femoral offset on posterior bony impingement. Results The range of external rotation and the ischiofemoral length were significantly lower, while femoral anteversion, the ischial ratio, and ischial angle were significantly higher in patients with posterior bony impingement compared with those who had implant impingement (p < 0.05). The range of external rotation positively correlated with ischiofemoral length (r = 0.49, p < 0.05), and negatively correlated with ischial length (r = -0.49, p < 0.05), ischial ratio (r =- 0.49, p < 0.05) and ischial angle (r = -0.55, p < 0.05). The range of external rotation was lower in patients with posterior pelvic tilt (p < 0.05) and in those with a high offset femoral component (p < 0.05) due to posterior bony impingement. Conclusion Posterior bony impingement after THA is more likely in patients with a wider ischium and a narrow ischiofemoral space. A high femoral offset and posterior pelvic tilt are also risk factors for this type of impingement. Cite this article: Bone Joint J 2017;99-B:1140–6.

Abstract
A 66-year-old man was diagnosed with a gastric submucosal tumor. Endoscopic ultrasound (EUS) revealed an iso/hypoechoic mass in the third layer. No malignant cells were detected in a histological examination. Yearly follow-up endoscopy and EUS showed the slow growth of the tumor. Endoscopic submucosal dissection (ESD) was performed and a glistening tumor was resected. The lesion showed a multinodular plexiform growth pattern consisting of spindle cells with an abundant fibromyxoid stroma that was rich in small vessels. The tumor was diagnosed as plexiform fibromyxoma (PF) by immunohistochemistry. Although difficulties are associated with reaching a diagnosis preoperatively, chronological changes on EUS may contribute to the diagnosis of PF. ESD may also be useful in the diagnosis and treatment of PF.

Abstract
INTRODUCTION This study describes our clinical experience of late conversion from antimetabolites with standard exposure calcineurin inhibitors (CNIs) to everolimus with CNI minimization in stable kidney transplant recipients with good graft function. PATIENTS AND METHODS A 1-year retrospective pilot study of 26 kidney recipients converted from antimetabolites with standard exposure CNIs to everolimus with CNI minimization was performed. The recipients enrolled in this study had normal or slightly impaired renal function defined as a serum creatinine value <2.0 mg/dL, and normal or slightly increased albuminuria defined as a urinary albumin excretion rate <100 mg/g creatinine. RESULTS The median time from transplant to conversion was 39.5 months posttransplant (range, 3-275). Treatment with everolimus was stopped owing to adverse events in 11 patients (42.3%). In the analysis of the patients in whom everolimus was maintained, the mean estimated glomerular filtration rate (eGFR) significantly increased from 50.7 ± 11.9 mL/min/1.73 m(2) at baseline to 53.6 ± 13.9 mL/min/1.73 m(2) at 1 year after conversion. In the patients in whom everolimus was stopped during the observation period, there was no difference in eGFR between baseline and 1 year after conversion. CONCLUSIONS This study demonstrated that, among the patients converted to everolimus at a late stage, there was no deterioration in renal function whether everolimus was maintained or stopped within 1 year after conversion.

Abstract
We report the case of a 62-year-old woman with a history of bilateral hearing impairment, who developed mitochondrial cardiomyopathy after chemotherapy. The patient underwent postoperative cisplatin chemotherapy after the surgical treatment of cervical cancer. The systolic function of her left ventricle decreased significantly. A tissue examination of the left ventricle revealed mitochondrial cardiomyopathy. Genetic testing revealed mutations in mitochondrial 3,243 A→G. Nine hundred fifty-five individual mutations were identified by next-generation sequencing. Since cardiovascular complications are the second leading cause of morbidity and mortality in patients undergoing cancer treatment, mitochondrial cardiomyopathy should be considered a potential cause of heart failure.

Abstract
Intrapulmonary aberrant needles are rarely encountered in clinical practice. A 82-year-old woman, though she was asymptomatic, was referred to our department due to an abnormal shadow on a chest X-ray. Chest X-ray and chest computed tomography showed a foreign body suspected to be a sewing needle in the left upper lobe. The needle was successfully removed by video-assisted thoracoscopic surgery.

Abstract
Abstract
In the vacuolar basic amino acid (VBA) transporter family of Saccharomyces cerevisiae, VBA4 encodes a vacuolar membrane protein with 14 putative transmembrane helices. Transport experiments with isolated vacuolar membrane vesicles and estimation of the amino acid contents in vacuoles showed that Vba4p is not likely involved in the transport of amino acids. We found that the vba4Δ cells, as well as vba1Δ and vba2Δ cells, showed increased susceptibility to several drugs, particularly to azoles. Although disruption of the VBA4 gene did not affect the salt tolerance of the cells, vacuolar fragmentation observed under high salt conditions was less prominent in vba4Δ cells than in wild type, vba1Δ, and vba2Δ cells. Vba4p differs from Vba1p and Vba2p as a vacuolar transporter but is important for the drug resistance and vacuolar morphology of S. cerevisiae.

Abstract
Patients undergoing surgery in the park-bench position are at high risk of developing intraoperatively acquired pressure ulcers (IAPUs). The purpose was to examine retrospectively risk factors associated with IAPUs in the park-bench position. This study was conducted at a general hospital during the period of September 2010 to September 2012. Twenty-one potential risk factors were evaluated using data obtained from the hospital database. IAPUs developed in 30 of 277 patients (11%). Perspiration was statistically found to be independently associated with IAPUs [OR 3·09, 95% confidence interval (Cl) 1.07-8·58, P = 0·037]. A length of surgery of more than 6 hours was identified to be likely associated with IAPUs (OR 2·64, 95% Cl 0·84-9·08, P = 0·095) compared with less than 6 hours. Furthermore, there was an interaction between the length of surgery and the core temperature; that is, when the length of surgery was more than 6 hours, a core temperature of more than 38·1°C at the end of surgery had a higher odds ratio (8·45, 95% Cl 3·04-27·46, P < 0·001) than that at a lower core temperature (3·20, 95% Cl 1·23-8·78, P = 0·017). These results suggest that perspiration and core temperature are preventable causative factors of pressure ulcers, even under conditions of prolonged surgery in the park-bench position.

Abstract
The ClpB/Hsp104 chaperone solubilizes and reactivates protein aggregates in cooperation with DnaK/Hsp70 and its cofactors. The ClpB/Hsp104 protomer has two AAA+ modules, AAA-1 and AAA-2, and forms a homohexamer. In the hexamer, these modules form a two-tiered ring in which each tier consists of homotypic AAA+ modules. By ATP binding and its hydrolysis at these AAA+ modules, ClpB/Hsp104 exerts the mechanical power required for protein disaggregation. Although ATPase cycle of this chaperone has been studied by several groups, an integrated understanding of this cycle has not been obtained because of the complexity of the mechanism and differences between species. To improve our understanding of the ATPase cycle, we prepared many ordered heterohexamers of ClpB from Thermus thermophilus, in which two subunits having different mutations were cross-linked to each other and arranged alternately and measured their nucleotide binding, ATP hydrolysis, and disaggregation abilities. The results indicated that the ATPase cycle of ClpB proceeded as follows: (i) the 12 AAA+ modules randomly bound ATP, (ii) the binding of four or more ATP to one AAA+ ring was sensed by a conserved Arg residue and converted another AAA+ ring into the ATPase-active form, and (iii) ATP hydrolysis occurred cooperatively in each ring. We also found that cooperative ATP hydrolysis in at least one ring was needed for the disaggregation activity of ClpB.
