- Abstract
A 75-year-old was treated for prostate adenocarcinoma with brachytherapy in September 2018. A routine follow-up chest radiograph 3 months later revealed a metallic object of the same dimensions as a brachytherapy pellet located in the right ventricle. Further imaging showed the brachtherapy pellet was located in the anterobasal right ventricular endocardium close to the tricuspid valve. Frequent asymptomatic premature ventricular contractions were observed with likely origin from the left ventricular outflow tract, an area remote from the site of the pellet. The patient remains asymptomatic and subsequent imaging shows that the position of the pellet has not changed., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

- Abstract
Background: An intracardiac foreign body causing recurrent fungemia is a rare clinical situation. Clinicians should be that aware of rare sources of sepsis despite a thorough history and examination., Results: The authors describe a 63 year-old man, with unremarkable past medical history, who presented with a fever for 2 weeks. Blood cultures persistently grew Candida albicans and Streptococcus constellatus. Echocardiogram assessment showed a suspected vegetation over the tricuspid valve. Surgical exploration with median sternotomy and cardiopulmonary bypass revealed a tooth-pick impacted within the right atrium surrounded by vegetation. The authors postulate accidental ingestion of the foreign body and translocation into the right atrium via the esophagus and thoracic cavity., Conclusion: Surgical removal of symptomatic intracardiac foreign bodies is highly recommended., (© 2020 Wiley Periodicals LLC.)

- Abstract
Metastasis is facilitated by the formation of pre-metastatic niches through the remodelling of the extracellular matrix (ECM) promoted by haematopoietic and stromal cells. The impact of these primed sites is pronounced for intraperitoneal metastases, where the cavity-exposed ECM supports the attachment of the disseminating tumour cells. Likewise, implantation of biomaterial scaffolds influences metastatic progression systemically through a foreign body reaction (FBR). In this study, we integrated the concept of creating an artificial niche to capture tumour cells actively disseminating in the peritoneal cavity with a therapeutic strategy modulating the interactions of metastatic cells with the ECM. The aim was to transform a disseminated disease into a focal disease. For this, we designed and developed a 'biomimetic' ECM composed of a nonresorbable three-dimensional scaffold with collagen coating and characterized the FBR to the implanted biomaterial. We also analysed the safety of the implanted devices and their ability to capture tumour cells in different murine preclinical models of advanced ovarian cancer. Implantation of the biomimetic devices resulted in an initial inflammatory reaction that transformed progressively into a fibrous connective tissue response. The adhesive capabilities of the scaffold were improved with the ancillary effect of the FBR and showed clinical utility in terms of the efficacy of capture of tumour cells, disease focalization and survival benefit. These results demonstrated the performance and safety of this 'biomimetic' ECM in preclinical models of advanced ovarian cancer. Translated into the clinical setting, this new therapeutic strategy represents the possibility for control of peritoneal carcinomatosis upon primary ovarian debulking surgery and to expand the percentage of patients who are candidates for second rescue surgeries at the time of relapse., (© 2020.

- Abstract
Patients undergoing transthoracic needle core lung biopsy (TTNB) are at risk for biopsy-related pneumothorax. Instilling pleural sealant at the pleural puncture site reduces this risk. The impact of histologic changes associated with pleural sealant on assessing the histologic type and pathologic stage in lung cancer resection specimens has not been previously evaluated. All lung cancer resection specimens from 2015 to 2018 in which polyethylene glycol hydrogel pleural sealant was instilled during TTNB were reviewed. Thirty-three cases were identified. TTNB preceded lobectomy by an average of 35 days. Amphophilic, weakly polarizable, crinkled pleural sealant material was associated with tumor in 11 cases (33%), including 8 adenocarcinomas, 2 squamous cell carcinomas, and 1 pleomorphic carcinoma that averaged 1.7 cm in greatest dimension. Surrounding the sealant material was a 0.25 to 1.0 cm in greatest dimension pseudocystic space with a thin granulomatous rim of macrophages and multinucleated giant cells that occupied on average 17% of the tumoral area. Pleural sealant could have impaired assessment of pathologic stage in 1 case by obscuring the visceral pleural elastic layer, but definitive visceral pleural invasion was present nearby. Although hydrogel pleural sealant instilled during TTNB has the potential to obscure important histologic features, in practice, it appears to have little or no adverse impact on the assessment of histologic type and pathologic stage in subsequent lung cancer resection specimens. Recognition of the histologic appearance of hydrogel pleural sealant and its associated tissue response is important for avoiding diagnostic misinterpretation.

- Abstract
Background: The subcutaneous implantable cardioverter defibrillator (S-ICD) is an alternative to the transvenous implantable cardioverter defibrillator for the prevention of sudden cardiac death. Here, we report a rare case of refractoriness to an S-ICD after frequent therapies for ventricular fibrillation (VF) storms., Case Presentation: A 24-year-old man underwent a bout of syncope with vomiting and incontinence at home. He was brought to the emergency room and was witnessed to spontaneously go into VF successfully converted by external defibrillation. Previously, he was diagnosed with a type I Brugada electrocardiogram pattern by a pilsicainide administration test in another hospital. Although he had a family history of sudden cardiac death in 3 relatives, including his brother, he was followed closely without any therapies because he had never had an episode of syncope. He was implanted with an S-ICD without any trouble. Seven months later, frequent S-ICD shocks for VF storms occurred. His VF was controlled by using intravenous amiodarone, which was converted to an oral preparation. However, his VF recurred after another 2 months. The analysis of his S-ICD data revealed that 4 consecutive shock deliveries could not terminate his VF and the final shock delivered could fortunately terminate it because of a high defibrillation threshold test (DFT) due to an increasing shock impedance (64 to 90 Ω). First, we performed an epicardial Brugada syndrome ablation and subsequently replaced and repositioned the S-ICD lead from a left to a right parasternal site. After the re-implantation of the S-ICD, the DFT test improved to within normal range. According to the pathological analysis, infiltration of inflammatory cells and extensive fibrosis were confirmed in the subcutaneous tissue around the shock lead and S-ICD body., Conclusion: Frequent S-ICD shocks for VF storms might cause various pathological changes around the device and lead to a high DFT.

- Abstract
Background: A small percentage of patients with foreign body ingestion develop complications, which have a variety of clinical presentations. Less than 1% of cases require surgical intervention. We present a patient with an abdominal wall abscess resulting from a fish bone that pierced the cecum. The patient was treated laparoscopically., Case Presentation: A 55-year-old Japanese man presented to our hospital with a complaint of right lower abdominal pain. A physical examination revealed tenderness, swelling, and redness at the right iliac fossa. Computed tomography showed a low-density area with rim enhancement in his right internal oblique muscle and a hyperdense 20 mm-long pointed object in the wall of the adjacent cecum. Based on the findings we suspected an abdominal wall abscess resulting from a migrating ingested fish bone. He was administered antibiotics as conservative treatment, and the abscess was not seen on subsequent computed tomography. Two months after the initial treatment, he presented with the same symptoms, and a computed tomography scan showed the foreign body in the same location as before with the same low-density area. We diagnosed the low-density area as recurrence of the abdominal wall abscess. He underwent laparoscopic surgery to remove the foreign body. His appendix, and part of his cecum and the parietal peritoneum that included the foreign body, were resected. He had an uneventful postoperative course, and at 1 year after the surgery, the abdominal wall abscess had not recurred., Conclusions: An abdominal wall abscess developed in association with the migration of an ingested fish bone. We suggest that a laparoscopic surgical resection of the portion of the bowel that includes the foreign body is a useful option for selected cases.

- Abstract
A 72-year-old man with a past medical history notable for deceased renal transplant presented to the interventional radiology department for routine right lower quadrant renal transplant nephroureteral catheter exchange. The nephroureteral catheter was placed in 2016 because of the presence of a hematoma causing partial page kidney and hydronephrosis. An antegrade nephrostogram was notable for opacification of the small bowel instead of the renal collecting system. The patient then subsequently developed urinary retention and intractable abdominal pain. Because of the combination of events, it was deemed necessary for laparotomy and surgical repair of the small bowel. Intraoperative findings were notable for small bowel adhesion to the abdominal wall but otherwise no evidence of acute inflammatory changes. In this case report, we describe the first case of an idiopathically dislodged nephrostomy catheter to the small bowel from a transplanted kidney and its successful management., (Published by Elsevier Inc.)

- Abstract
Metal endoclips are frequently utilized in surgical procedures. Within the medical literature, metal endoclip migration following general surgical procedures is a widely studied complication. However, examples of thoracic metal endoclip migration are, as yet, absent in the medical literature. This case study seeks to provide the first clear example of such thoracic metal endoclip migration., (© The Author(s) 2018.

- Abstract
Introduction: Iatrogenic embolization following cardiac investigative procedures may result from hydrophilic polymer emboli (HPE) from catheter valve and vessel wall calcifications, and air embolism from open heart surgery. This retrospective clinical pathologic analysis was undertaken to ascertain the frequency and extent of these potentially fatal complications., Methods: This retrospective clinical pathologic autopsy analysis with premortem diagnostic imaging correlation identified 110 individuals who had undergone endovascular procedures between 2010 and 2016 within 90 days of death and followed by hospital autopsy. Clinical outcomes, radiologic studies, and autopsy materials were reviewed., Results: Iatrogenic emboli were assessed as causing death in 9/110 autopsy cases (8.2%) and 9/34 (26.5%) cases with proven iatrogenic emboli. Iatrogenic emboli caused strokes in 10/110 (9.1%) autopsy cases including calcified emboli (CE, n=6), HPE (n=2), cardiac valvular tissue (n=1), and air embolism (n=1). Seven cases of calcified emboli complicating endovascular procedures were identified: four of the CE were thought to be the cause of death due to fatal strokes (n=2) and fatal myocardial (n=1) and colonic infarction (n=1). The CE likely originated from calcified aortic valves and atherosclerotic aortic plaques. Histologic evidence of HPE was found in 23% (25/110) of cases; 54% (26/48) showed evidence of infarction in postprocedural imaging, with radiologic evidence of infarction in 32% (8/25) of cases with HPE histology. Endovascular aortic repair was associated with the greatest density/distribution of HPE. HPE material showed degradation with time and was often associated with an inflammatory response. HPE directly contributed to death in three cases. One fatal air embolism followed open heart surgery, and one cardiac tissue embolus resulted in a major stroke., Conclusions: We advocate for greater awareness of these underrecognized and occasionally fatal complications of endovascular procedures. Targeted postprocedural imaging has a role in the identification of iatrogenic embolic infarcts., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
The mortality rate of aortic aneurysm/dissection is low in Japan. Two surgical procedures, the thoracic endovascular aortic repair (TEVAR) and the open stent-grafting have contributed much in survival of such aneurysmal patients. We encountered with two autopsy cases of death by aortic rupture with fistula formation after these procedures. Case 1 is an 85-year-old male who had the history of TEVAR for thoracic aorta aneurysm one and a half year before his death. His endovascular stent-graft was composed of a steel endoskeleton consisting of six Z-shape elements while at autopsy, one of the elements locating at the distal part was found inserted deep into the wall of descending aorta, causing aorto-esophageal fistula. Case 2 is an 88-year-old male who had the history of open stent-grafting for aortic aneurysm eight years ago. At autopsy, the stent-graft was found detached from aorta at its lesser curvature, causing gap formation between the aorta and the stent. Six Z-shaped stent elements, the parts of stent-graft, were found separated from descending aorta and located in the aneurism. Furthermore, three of the separated elements were found inserted deep in the aortic wall, causing aorto-pulmonary fistula. Since aorto-esophageal fistula formation after surgery for aortic aneurysm is very rare in TEVAR and there are no reported cases of death by aorto-pulmonary fistula in the open stent-grafting, these cases are reported here., (Copyright © 2018 Elsevier Inc.

- Abstract
Background: Polypropylene mesh is used widely for surgical treatment of pelvic organ prolapse and stress urinary incontinence. Although these surgeries demonstrate favorable functional and anatomic outcomes, their use has been limited by complications, the 2 most common being exposure and pain. Growing evidence suggests that T lymphocytes play a critical role in the regulation of the host response to biomaterials., Objective: The purpose of this study was to define and characterize the T-cell response and to correlate the response to collagen deposition in fibrotic capsules in mesh tissue complexes that are removed for the complications of pain vs exposure., Study Design: Patients who were scheduled to undergo a surgical excision of mesh for pain or exposure at Magee-Women's Hospital were offered enrollment. Forty-two mesh-vagina tissue complexes were removed for the primary complaint of exposure (n=24) vs pain (n=18). Twenty-one patients agreed to have an additional vaginal biopsy away from the site of mesh that served as control tissue. T cells were examined via immunofluorescent labeling for cell surface markers CD4+ (T
h ), CD8+ (cytotoxic) and foxp3 (T-regulatory cell). Frozen sections were stained with hematoxylin-eosin for gross morphologic condition and picrosirius red for collagen fiber analysis. Interrupted sodium-dodecyl sulfate gel electrophoresis was used to quantify the content of collagens type I and III, and the collagen III/I ratio. Transforming growth factor-β and connective tissue growth factor, which are implicated in the development of fibrosis, were measured via enzyme-linked immunosorbent assays. Data were analyzed with the Student's t tests, mixed effects linear regression, and Spearman's correlation coefficients., Results: Demographic data were not different between groups, except for body mass index, which was 31.7 kg/m2 for the exposure group and 28.2 kg/m2 for pain (P=.04). Tissue complexes demonstrated a marked, but highly localized, foreign body response. We consistently observed a teardrop-shaped fibroma that encapsulated mesh fibers in both pain and exposure groups, with the T cells localized within the tip of this configuration away from the mesh-tissue interface. All 3 T-cell populations were significantly increased relative to control: CD4+ T helper (P<.001), foxp3+ T regulatory (P<.001), and CD8+ cytotoxic T cell (P=.034) in the exposure group. In the pain group, only T-helper (P<.001) and T-regulatory cells (P<.001) were increased, with cytotoxic T cells (P=.520) not different from control. Picrosirius red staining showed a greater area of green (thin) fibers in the exposure group (P=.025) and red (thick) fibers in the pain group (P<.001). The ratio of area green/(yellow + orange + red) that represented thin vs thick fibers was significantly greater in the exposure group (P=.005). Analysis of collagen showed that collagen type I was increased by 35% in samples with mesh complications (exposure and pain) when compared with control samples (P=.043). Strong correlations between the profibrosis cytokine transforming growth factor-β and collagen type I and III were found in patients with pain (r≥0.833; P=.01) but not exposure (P>.7)., Conclusion: T cells appear to play a critical role in the long-term host response to mesh and may be a central pathway that leads to complications. The complexity of this response warrants further investigation and has the potential to broaden our understanding of mesh biology and clinical outcomes., (Copyright © 2018.

- Abstract
Objectives: The aim of this study was to evaluate the subcutaneous response induced by Roeko Guttaflow2 (RG), Sealapex Xpress (SX), AH Plus (AHP) sealers., Methods: 100 BALB/c mice received implants in the subcutaneous tissue with the tested materials (10 animals per period for each evaluated sealer) and were evaluated after different experimental periods (7, 21 and 63 days), in each animal was placed a tube, the control group was an empty tube. Histological analysis evaluated semi-quantitatively the inflammatory infiltration, collagen fiber formation and tissue thickness. In addition, immunohistochemistry was performed for interleukin-6 (IL-6). Data were statistically analyzed (α = 0.05)., Results: RG promoted a greater collagen fiber formation at 7 days and 63 days compared to the CG (p = 0.004) and AHP (p = 0.005) respectively, while at 21 days, the SX promoted a greater reaction (p = 0.021). For the tissue thickness, there was a greater reaction at 7 days with CG (p = 0.0156) and with RG at 63 days (p = 0.03). Regarding the inflammatory infiltrate, there was no difference at 7 days and 63 days (p = 0.5; p = 0.27), while at 21 days, a statistically difference was found between SX, CG (p = 0.04) and RG (p = 0.027). In addition, the presence of IL-6 was observed in almost all groups, with a more intense marking at 7days., Significance: All cements evaluated presented a satisfactory tissue response, however, RG was the one that presented a more satisfactory tissue response., (Copyright © 2018 Elsevier Masson SAS.

- Abstract
Nexplanon is a long-acting 4cm radio-opaque rod shaped contraceptive device implanted in the subdermal layer of the inner, upper arm. Complications from implantation are uncommon and mostly local and minor, including infection at the implantation site with resulting cellulitis or abscess, hematoma, abnormal scar formation, or local damage to nerves and blood vessels. Intravascular insertion is estimated to be at 1.3 per million Nexplanon implants, and migration and embolization is a rare complication of this device. We present a case report of a 16year old female who presented to the pediatric emergency department with subjective dyspnea and an embolized contraceptive device within a subsegmental branch of the left lower lobe pulmonary artery. After discussion with consultants, interventional radiology was able to successful retrieve the device without complication., (Copyright © 2018 Elsevier Inc. All rights reserved.)

- Abstract
In daily practice, the iatrogenic complication hydrophilic polymer embolization (HPE) is under-recognized. An 86-year-old male experienced a distal foot embolization after transcatheter aortic valve replacement. Rashes appeared only in the access side foot just after the procedure. Gradual worsening of the rashes was first thought to be cholesterol crystal embolization (CCE), but a pathological examination revealed HPE. The clinical course following the diagnosis was uneventful without notable treatment. We experienced a rare but important alternative differential diagnosis of CCE after catheter intervention.

- Abstract
Migrating bullets are rare sequelae of penetrating gunshot wounds. Such cases have been described in the neurosurgical literature because they can produce complications in the management of patients such as decline in neurologic status, delays in rehabilitation, and difficulties in bullet removal. In contrast, few postmortem reports have described this phenomenon. We report a case of a gunshot wound in which the projectile entered the left side of the head and traversed to the right frontal area as documented by CT scan on hospital admission. At autopsy, the bullet was noted to have migrated back to the left side of the head from where it was recovered. Medical examiners need to be aware of this unusual phenomenon of retained intracranial projectiles., (© 2017 American Academy of Forensic Sciences.)

- Abstract
Objective: This study aimed to evaluate migration of the receiver-stimulator after cochlear implantation using the subperiosteal pocket technique., Methods: A prospective clinical study was performed of 32 paediatric patients (aged between 12 months and 8 years; mean ± standard deviation, 28 ± 19 months) who underwent cochlear implantation in tertiary referral centres. The degree of migration was evaluated using measurements between the receiver-stimulator and selected reference points: the lateral canthus, tragus and mastoid tip. All distances were measured during and six months after surgery., Results: No receiver-stimulator migration was observed when using the subperiosteal pocket technique., Conclusion: Concerns about implant migration in the subperiosteal pocket technique are unwarranted: this is a safe technique to use for cochlear implantation.

- Abstract
Endoscopic retrograde cholangiopancreatography (ERCP) routinely uses hydrophilic guidewires to cannulate ducts and traverse stenoses. Fracture of these guidewires have been reported, however, migration of these fractured fragments is an extremely rare occurrence that has yet to be reported in the literature. We present a case of a fractured ERCP guidewire with extensive migration in the retroperitoneal and lower extremity soft tissues and vasculature with radiologic correlation across multiple modalities-MRI, CT, and radiographs-as well as pathologic correlation. This case illustrates a rare but serious complication of ERCP and demonstrates the imaging findings associated with it., (Copyright © 2017 Elsevier Inc. All rights reserved.)

- Abstract
Filler migration is a potential complication following the injection of multiple fillers. With the increasing popularity of multiple filler injections, migrated granulomas should be an essential differential diagnosis for newly growing facial lumps. It is important for all physicians to be aware that complication induced by dermal fillers can occur in locations other than the planned injected sites. We described a case of filler migration to the forehead in a patient addicted to cosmetic fillers. To our knowledge, it has never been published in dermatology literature so far. A detailed history of cosmetic procedures from the patient addicted to filler injections is necessary for accurate diagnosis. Because account of previous cosmetic filler injections is not always reliable, an early skin biopsy with pathological examination is the gold standard for determining whether multiple filler injections have been performed.

- Abstract
Aims: The purpose of this study was to determine the sensitivity, specificity and predictive values of previously reported thresholds of proximal translation and sagittal rotation of cementless acetabular components used for revision total hip arthroplasty (THA) at various times during early follow-up., Patients and Methods: Migration of cementless acetabular components was measured retrospectively in 84 patients (94 components) using Ein-Bild-Rontgen-Analyse (EBRA-Cup) in two groups of patients. In Group A, components were recorded as not being loose intra-operatively at re-revision THA (52 components/48 patients) and Group B components were recorded to be loose at re-revision (42 components/36 patients)., Results: The mean proximal translation and sagittal rotation were significantly higher in Group B than in Group A from three months onwards (p < 0.02). Proximal translation > 1.0 mm within 24 months had a positive predictive value (PPV) of 90% and a specificity of 94%, but a sensitivity of 64%. Proximal translation > 1.0 mm within the first 24 months correctly identified 76 of 94 (81%) of components to be either loose or not loose. However, ten components in Group B (24%) did not migrate proximally above 1.0 mm within the first 60 months., Conclusion: The high PPV of EBRA-Cup measurements of proximal translation (90%) shows that this can be used in early follow-up to identify patients at risk of aseptic loosening. The absence of proximal translation within the first 60 months indicates a component is not likely to be loose at re-revision THA although it does not exclude late aseptic loosening as a cause of failure.

- Abstract
Objectives: The aim of this article was to summarize the efficacy and safety of venous stents in chronic obstructive venous disease (COVD) including postthrombotic syndrome (PTS) and nonthrombotic iliac vein lesions (NIVL)., Methods: We searched PubMed for case series (prospective and retrospective) that focused on venous stents in the treatment of COVD published between 1st January, 2000 and 15th July, 2014. Then, we analyzed the perioperative complications, subsequent antithrombotic treatment, clinical outcomes, and long-term patency of this procedure., Results: Overall, 1987 patients from 14 studies were included in our study. The incidence of the 30-day thrombotic events was 2.0% (4.0% in PTS vs. 0.8% in NIVL, p = 0.0002). The rates of access site complications and stent migration were 1.7% and 1.3%, respectively. The incidence of retroperitoneal bleeding and contrast extravasation was 1.8%. Back pain was more common with a rate of 62.9%. With stent placement, there was a significant pain and edema relief in COVD patients and the clinical-etiology-anatomy-pathophysiology scores declined. The rate of ulcer healing was 72.1% (70.3% in PTS vs. 86.9% in NIVL, p = 0.0022), and the ulcer recurrence rate was 8.7%. The primary, assisted primary, and secondary patency rates were 91.4%, 95.0%, and 97.8%, respectively, at 12 months and 77.1%, 92.3%, and 94.3%, respectively, at 36 months; however, the patency rates in PTS were lower than those in NIVL., Conclusions: Stents may be a relatively effective and safe approach for PTS and NIVL patients because of the low incidence of perioperative complications and satisfying long-term patency. Some outcomes of stents in NIVL patients may be better than those in PTS patients., (© The Author(s) 2015.)

- Abstract
Bullets can lodge in the organs, blood vessels or thecal sac. To our knowledge, a migrating bullet at the level of the conus medullaris without neurological deficit has never been reported. We present our patient along with a discussion of bullet migration in the spinal canal and its mechanisms, diagnosis and treatment. A 29-year-old man was admitted to the emergency department due to a gunshot wound in the right upper quadrant of his abdomen. He had no neurological deficit. Spinal CT scan and plain radiography showed the bullet had passed through the L2 vertebral body and had migrated downwards until it had lost its energy and come to rest in the spinal canal at the L3 vertebra level. There was a grade 5 injury to the pancreas head concomitant with mesenteric injury of the transverse colon, harboring a 0.5 cm hole. He had an emergent laparotomy to have a Roux-en-Y reconstruction and repair of the transverse colon. After his general status stabilized, he was taken back to the operating room to extract the bullet from the spinal canal. L3 and partial L2 laminectomy were performed. The dura was opened and the bullet was observed intrathecally. No cerebrospinal fluid fistula was observed. The surgeries and post-operative period were uneventful., (Copyright © 2016 Elsevier Ltd.

- Abstract
The purpose of the study was to evaluate the distribution and amount of pseudoexfoliation material (PXM) on anterior segment structures in pseudophakic human autopsy eyes with pseudoexfoliation (PEX) syndrome and to study its impact on fixation and decentration of posterior chamber intraocular lenses (IOLs). Sixteen human autopsy eyes (donor age [mean ± SD] 77.5 ± 8.6 years; range, 70-90 years) with history of cataract surgery and PEX syndrome were analyzed for distribution and accumulation of PXM on structures of the anterior segment by light microscopy. Quantitative IOL decentration measurements were performed using the Miyake-Apple posterior view technique. All 16 eyes displayed IOLs which were either fixed symmetrically in the capsular bag (n = 8) or asymmetrically with one haptic in the sulcus and one in the bag (n = 7) or at the pars plicata of the ciliary body (n = 1). In the majority, PXM was found around the pars plicata (average grade: 1.6 ± 0.53 µm) and the lens capsule (average grade: 1.05 ± 0.46 µm). Minor amounts were detected at the pars plana and the trabecular meshwork. IOL decentration measurements ranged from 0.51 ± 0.35 (symmetrical-fixation) to 0.61 ± 0.43 mm (asymmetrical-fixation). There was only a weak statistically not significant correlation in regard to the amount of PXM and IOL decentration and between PXM distribution and the IOL fixation site. PXM contributes to weakening of the suspensory apparatus of the crystalline lens. Although PXM induced tissue alterations predispose for a broad spectrum of intra- and postoperative complications, the amount and distribution of PXM on different anterior segment structures showed only a weak correlation to IOL decentration or fixation location.

- Abstract
Aims: We sought to evaluate the incidence of embolic material in porcine brains following vascular interventions using hydrophilic-coated sheaths., Methods and Results: A new self-expanding stent and delivery system (SDS) was deployed through a hydrophilic-coated (Flexor Ansel; Cook Medical, Bloomington, IN, USA) guiding sheath into the iliac and/or carotid arteries of 23 anaesthetised Yucatan mini swine. The animals were euthanised at three, 30, 90 and 180 days and their brains were removed for histological analysis. In an additional single control animal, the guiding sheath was advanced but no SDS was deployed. Advancement of the coated guiding sheath with or without the SDS was associated with frequent foreign material in the arterioles of the brain. The embolic material was amorphous, non-refractile, non-crystalline, non-birefringent and typically lightly basophilic with a slightly stippled appearance on haematoxylin and eosin (H&E) stain. Material was observed at all time points involving 54% of all study animals (i.e., test and control) and in vitro after incubation in 0.9% saline., Conclusions: The hydrophilic coating on a clinically used guiding sheath readily avulses and embolises to the brain during deployment in a porcine model. Further documentation of this effect and monitoring in clinical scenarios are warranted.

Introduction: Adverse effects on the oral mucosa after the use of dermal fillers have been reported due to their increased use for facial aesthetics., Objective: This study aimed to evaluate, clinically and histologically, the local and systemic effects of two concentrations of polymethylmethacrylate (PMMA) dermal filler in rats., Material and Methods: Fifty-four female rats were allocated into three treatment groups (2% PMMA, 30% PMMA and 0.9% NaCl), according to the substance injected in the tongue, and three experimental periods: 7, 60 and 90 days. The rats were clinically evaluated and then euthanised, and their tongue and right kidney removed. The histological sections were stained with haematoxylin/eosin and picrosirius., Results: Clinically, significant differences were found between test groups as to the occurrence of nodules (Kruskal-Wallis; p < 0.001). Histologically, there was greater inflammatory response in the PMMA compared with control (Kruskal-Wallis; p < 0.001). 30% PMMA had greater collagen formation (anova mixed models; p < 0.01). No migration of the material towards kidney was found., Conclusion: Polymethylmethacrylate induced intense reaction in the initial period of observation (7 days), followed by gradual decrease during the study, favouring the presence of fibroplasia adjacent to the material., (© 2014 John Wiley & Sons A/S and The Gerodontology Society.

- Abstract
Background: Accidental displacement of a dental implant into the maxillary sinus is an infrequent although not uncommon complication encountered in dental clinical practice, with the main cause thought to be inadequate bone height in the posterior maxilla. We report a case of migration of a dental implant into the maxillary sinus, and discuss the benefits of its removal by a combination of endoscopically assisted and bone repositioning techniques., Case Presentation: A 35-year-old Japanese man with a partially edentulous maxilla underwent implant placement at a private clinic. Three months later, at the time of abutment connection, the implant at the site of his maxillary right first molar was accidentally pushed into the sinus. The hole on the alveolar ridge made for placement of the implant was small and far from the dislocated implant, thus access was achieved in a transoral manner via the frontal wall of his maxillary sinus with an endoscopic approach. Piezoelectric instruments were used to perform an osteotomy. The bone lid was removed, and the implant was identified using a rigid endoscope and removed with a surgical aspirator, followed by repositioning of the bony segment; the area was secured with an absorbable suture. Removal of migrated implants should be considered in order to prevent possible sinusal disease complications., Conclusions: In the present case, removal of a dental implant displaced into the maxillary sinus by use of a combination of endoscopically assisted and bone repositioning techniques proved to be a safe and reliable procedure.

- Abstract
A 64-year-old man was referred to our hospital for treatment of a cerebral aneurysm that was incidentally found. The aneurysm was 7 mm in size and located on the left anterior communicating artery. Using a balloon assisted technique, we performed coil embolization. During the second coil insertion, the first coil was dislodged into the anterior communicating artery. We attempted coil retrieval using a snare, which was unsuccessful. We applied a direct aspiration first pass technique (ADAPT) and advanced a Penumbra 4MAX immediately proximal to the dislodged coil; the dislodged coil was then successfully retrieved. ADAPT is a simple procedure for retrieval of a detached coil, and it can be used as an alternative to the snare technique., (2015 BMJ Publishing Group Ltd.)

- Abstract
Electrode migration/displacement is reported to be the most common complication of spinal cord stimulator (SCS) implantation, with the literature reporting incidences from 13.2% to 22.6%. There have been numerous publications describing techniques preventing lead migration, with most involving tying leads to skin and fascia for trial and permanent leads, respectively. However, few have addressed how to prevent migration in the case of hypermobile tissue seen in the morbidly obese. We describe the creation of subcutaneous tension loops to prevent lead migration.

- Abstract
In this report, we present a unique complication of hemodialysis: the hemodialysis access needle was lost into an arteriovenous fistula. The event went unnoticed for several months. The needle eventually migrated into the right ventricle, requiring an operative retrieval. Loss of the needle was likely unrecognized because of the use of a retracting safety cannula that conceals the needle within a sheath after removal. This case highlights a rare and potentially serious complication of hemodialysis access, demonstrates a possible hazard of retracting safety needles, and reviews the management of foreign bodies that have migrated into the heart.

- Abstract
Introduction: The ingestion of foreign bodies is a frequently observed problem in daily clinical practice. In order to avoid complications such as perforation, endoscopic removal of potentially penetrating foreign bodies should be attempted quickly. The use of various endoscopic techniques has been reported for this purpose. However, extraction of foreign bodies from the mid gastrointestinal tract has rarely been reported., Case Report: We present the case of a patient who had swallowed a safety needle which could safely be removed from the jejunum by means of double-balloon enteroscopy (DBE). The combination of a thin p-type enteroscope with a thick t-type overtube was used in order to improve the manoeuvrability of the endoscope. The needle was pulled into the overtube which served as a protective shield during the retrieval of the endoscope., Conclusion: Our case report describes the potential of removing foreign bodies from the deep small bowel by pulling them into the overtube of a double-balloon enteroscope. If the suspicion of foreign body impaction in the small bowel is made, it may be advisable to primarily choose a balloon enteroscopy system. Through this, quick and deep insertion can be combined with a safe removal of the foreign body., (© Georg Thieme Verlag KG Stuttgart · New York.)

- Abstract
Renal function impairment during interventional procedures became a real clinical problem. Contrast related nephropathy is the most common cause of renal failure, however, the procedure-related technical troubles may cause unexpected renal dysfunction.Technical failure of EVAR resulting in acute renal dysfunction is presented. The postprocedural occlusion of the right renal artery was treated in chimney technique. Early reintervention allowed the kidney preservation and renal function restoration. It is impossible to avoid all the complications following treatment of aortic aneurysm, but they can be anticipated and comprehensively treated in collaboration with other specialists.

- Abstract
An adductor canal catheter may facilitate early ambulation after total knee arthroplasty, but there is concern over preoperative placement since intraoperative migration of catheters may occur from surgical manipulation and result in ineffective analgesia. We hypothesized that catheter type and subcutaneous tunneling may influence tip migration for preoperatively inserted adductor canal catheters. In a male unembalmed human cadaver, 20 catheter insertion trials were divided randomly into one of four groups: flexible epidural catheter either tunneled or not tunneled; or rigid stimulating catheter either tunneled or not tunneled. Intraoperative patient manipulation was simulated by five range-of-motion exercises of the knee. Distance and length measurements were performed by a blinded regional anesthesiologist. Changes in catheter tip to nerve distance (p = 0.225) and length of catheter within the adductor canal (p = 0.467) were not different between the four groups. Two of five non-tunneled stimulating catheters (40 %) were dislodged compared to 0/5 in all other groups (p = 0.187). A cadaver model may be useful for assessing migration of regional anesthesia catheters; catheter type and subcutaneous tunneling may not affect migration of adductor canal catheters based on this preliminary study. However, future studies involving a larger sample size, actual patients, and other catheter types are warranted.
