A for-cause biopsy is performed to diagnose the cause of allograft dysfunction in kidney transplantation. We occasionally encounter ambiguous biopsy results in symptomatic kidney transplant recipients. Yet, the allograft survival outcome in symptomatic recipients with nonspecific allograft biopsy findings remains unclear. The purpose of this study was to analyze the impact of nonspecific for-cause biopsy findings in symptomatic kidney transplant recipients. We retrospectively collected records from 773 kidney transplant recipients between January 2008 and October 2021...

Bacille Calmette-Guérin( BCG) intravesical therapy is an effective and safe treatment for bladder cancer; however, mycotic aneurysms have been reported as a rare complication. Case 1:A 64-year-old man with a history of BCG intravesical therapy underwent emergent thoracic endovascular aortic repair (TEVAR) for a ruptured thoracic aortic aneurysm (TAA). He was diagnosed with BCG infection by hemosputum specimen culture five months later;then, antituberculous therapy was initiated. However, his follow-up computed tomography scan revealed stent-graft infection and new aneurysm formation...

This study aimed at developing a fully automatic technique for right lobe graft weight estimation using deep learning algorithms. The proposed method consists of segmentation of the full liver region from computed tomography (CT) images, classification of the entire liver region into the right and left lobes, and estimation of the right lobe graft weight from the CT-measured right lobe graft volume using a volume-to-weight conversion formula. The first two steps were performed with a transformer-based deep learning model...

A 69-year-old patient presented with a 9-month history of constitutional symptoms and a 3-week history of increasing abdominal and back pain. He had a history of bacillus Calmette-Guérin immunotherapy for bladder cancer 9 months earlier. An infrarenal mycotic aneurysm was detected by positron emission tomography-computed tomography. His abdominal aorta was reconstructed using a tube graft tailored from a bovine pericardium sheet. We chose this graft because of its acellular nature and reduced risk of postoperative infection...

A 3-month-old female infant, born to consanguineous healthy parents, presented with splenomegaly, erythroderma, failure to thrive, and history of recurrent otitis media, hypothyroidism, and Bacille Calmette-Guérin lymphadenitis following Bacille Calmette-Guérin vaccination...

BACKGROUND Even with recent data, 5-10% of pancreas transplants experience early technical failure. Graft thrombosis is the primary cause of early technical failure, even when only optimal grafts are used, as is the case in Korea. The purpose of this study was to determine whether we can avoid thrombotic graft failure by modifying venous outflow. MATERIAL AND METHODS Between March 2017 and December 2021, a total of 59 pancreas transplantations were performed. Until May 2019, 31 cases of fence-angioplasty with cadaveric vena cava were performed to graft portal veins (the vena cava group)...

Common carotid artery (CCA) rupture during parathyroid cancer surgery is extremely rare and is generally life-threatening. We present a case of successful management of a ruptured CCA following the emergency placement of stent-graft in a 59-year-old male diagnosed with recurrent parathyroid cancer. During recurrent parathyroid cancer surgery, his right CCA ruptured unexpectedly, and his vital signs deteriorated rapidly despite surgical management. After stent replacement, his unstable vital signs improved and, thereafter, he was discharged without any complications...

Graft-versus-host disease is a rare but a potentially fatal complication that can occur after kidney transplant. Furthermore, graft-versus-host disease after kidney transplant has been reported in only a few studies. We present a rare case of graft-versus-host disease in a patient who underwent kidney transplant. A patient who underwent hemodialysis received an en bloc kidney transplantfrom a pediatric donor, and the graft function was excellent. Mild diarrhea started on postoperative day 25. Six days after the onset of diarrhea, pancytopenia worsened and fever persisted...

BACKGROUND: Delayed graft function (DGF) is a serious complication associated with worsening outcomes in kidney transplantation. To facilitate DGF risk reduction, this study aimed to identify the incidence and modifiable risk factors of this condition in kidney transplant patients. METHODS: This retrospective chart review included 220 patients who underwent kidney transplants between 2012 and 2021 at our kidney transplant center. Delayed graft function was defined as the requirement of hemodialysis within a week of transplantation...

Infrastructure maxillectomy is a surgical procedure to remove the lower part of the maxilla and hard palate. The objective of the present study was to analyze clinical data and treatment outcome of patients who underwent infrastructure maxillectomy between 2011 and 2019. A total of 13 patients who underwent infrastructure maxillectomy for maxillary sinus and hard palate neoplasms between 2011 and 2019 were analyzed. These patients were subdivided into maxillary sinus neoplasm (n=5) and hard palate neoplasm (n=8) groups...

Introduction: Iatrogenic diaphragmatic hernias is rare complications of abdominal or thoracic surgery. Depending on the location and size of the defect retroperitoneal or intra-abdominal organs and tissues can prolapse into thoracic cavity due to the negative intra-thoracic pressure. This can cause risk of obstruction or strangulation of abdominal contents, and may ischemia and perforation. Methods: We present a case of delayed presentation of a patient with iatrogenic diaphragmatic herniation of liver and gallbladder with stones into the thorax...

BACKGROUND: Transoesophageal echocardiography (TOE) is a safe and useful tool. In our case, we are presenting a rare case of a patient with aortic dissection during TOE procedure. CASE SUMMARY: A 79-year-old woman was referred to our hospital for recurrent paroxysmal atrial fibrillation (AF) with palpitation. Pre-procedural cardiac computed tomography (CT) showed slight dilated ascending aorta (maximum diameter: 40 mm). We decided to perform catheter ablation (CA) for AF, and recommended TOE before the CA because she had a CHADS2 score of 4...

Pumpkins ( Cucurbita moschata ) are one of the most important economic crops in genus Cucurbita worldwide. They are a popular food resource and an important rootstock resource for various Cucurbitaceae. Especially, C. moschata is widely used as a rootstock for the commercial production of bloomless cucumbers in East Asia. Since the genetic diversity of the commercial rootstock varieties is narrow, there has been an increasing demand for the trait development of abiotic and biotic stress tolerance breeding. In this study, 2071 high-quality SNPs that were distributed evenly across 20 chromosomes of pumpkins were discovered through the genotyping-by-sequencing (GBS) analysis of 610 accessions of C...

Vacuolar myelopathy (VM) is known to be a neurological complication in patients with acquired immunodeficiency syndrome (AIDS). In autopsy-based studies, VM was reported in approximately 20-50% of patients with AIDS. It manifests in various says, mainly presenting as a painless spastic paraparesis with a sensory ataxia. We present a rare case of VM after bone marrow transplantation (BMT) in a patient without AIDS. A 50-year-old man developed weakness in the lower legs, leg muscle atrophy, and difficulty in walking 86 days after BMT...

PURPOSE: To assess the feasibility and effectiveness of retrograde intramedullary nail (RIN) revision surgeries for locking compression plate (LCP) failure in distal femoral fractures. METHODS: This retrospective study included 13 patients who suffered from metalwork failures after they initially underwent open reduction and LCP fixation. In patients who eventually underwent RIN revision from January 2014 to December 2016, range of motion (ROM) and Hospital for Special Surgery (HSS) scores obtained before surgery and at the final follow-up time were analysed...

Molecular chaperones are key components of the protein homeostasis system against protein misfolding and aggregation. It has been recently shown that these molecules can be rationally modified to have an enhanced activity against specific amyloidogenic substrates. The resulting molecular chaperone variants can be effective inhibitors of protein aggregation in vitro, thus suggesting that they may provide novel opportunities in biomedical and biotechnological applications. Before such opportunities can be exploited, however, their effects on cell viability should be better characterised...

INTRODUCTION: Non-unions at forearms are usually challenging and difficult to treat. If additionally, an infection is present, reconstructive surgery should be planned only after full debridement, antibiotic treatment, and confirmation, based on clinical observation and laboratory tests that the infection has subsided. Bone grafting may be required for reconstruction. The use of autogenous bone calls for a second surgical site with an increased risk of morbidity. Using bone substitutes may reduce the need for autogenous bone...

A novel hyaluronan (HA) derivative, poly(L-glutamic acid)-grafted hyaluronan (PGA-g-HA), was synthesized to improve the durability of conventional HA products for intra-articular injection. The purpose of this study was to investigate the characteristics of the novel HA derivative in terms of viscoelasticity, degradation behavior, non-immunogenicity, and bioactivity using preliminary in vitro and in vivo experiments. The storage modulus (G') and loss modulus (G″) of PGA-g-HA were similar to those of HA80 (approximately 8...

INTRODUCTION: To date, clinically available expanded polytetrafluoro-ethylene (ePTFE) vascular grafts are suboptimal for reconstructing small caliber (D < 6 mm) arteries, owing to thrombosis in early and restenosis in late stage. Our aim in this preliminary study was to fabricate a nano-fibrous vascular graft which was biofunctionalized with VEGF165 and heparin. The short term performance was evaluated both in vitro and in vivo. METHOD: Four-mm caliber grafts were prepared by the coaxial-elctrospun technique, which consisted of poly(l-lactide-co-caprolactone) [P(LLA-CL)] collagen and elastin...
