These were mostly related to myeloid cells and innate immunity. Genes negatively associated with costimulation blockade (n = 14) could be linked to B-cell differentiation and proliferation. We concluded that expression levels of genes characteristic of TCMR are strongly interconnected with quantitative changes of the biopsy inflammatory load. Our results might suggest differential involvement of the innate immune system, and an altered B-cell engagement during TCMR in belatacept-treated patients relative to CNI-treated referents.

Secondary cardiac tumors are far more frequent than primary tumors. Cardiac metastasis of osteosarcoma is extremely rare.

We report a 14-year-old child with left femur osteosarcoma that had metastasized to the left ventricle after 30 months of follow-up. The diagnosis was confirmed based on the findings of transthoracic echocardiography and fluorodeoxyglucose positron emission tomography/computed tomography. Surgical removal was indicated in the patient, but his parents refused this decision, and the patient was discharged and admitted to a pediatric oncology center for chemotherapy. The patient died after four courses of chemotherapy.

Cardiac metastasis of osteosarcoma is a strong predictor of disease. The demographic differences shown in our case include male sex and a short interval between onset and cardiac involvement.

After becoming a responder initially, he experienced significant clinical worsening on follow-up. Device interrogation revealed several long episodes of inappropriate automatic mode switch (AMS) entry due to far-field R wave oversensing resulting in loss of atrioventricular synchrony. Moreover, pacing in VVI mode with consistent VA conduction taking place during the AMS episodes was also found to be detrimental, which helped in sustaining the episodes and produced pacemaker syndrome like phenomenon. Attempts made to resolve the issue by prolonging the post-ventricular atrial blanking period was unsuccessful, hence we adjusted the atrial channel sensitivity to troubleshoot the problem.We report a rare case of infective endocarditis complicated by postoperative splenic rupture. A patient underwent urgent mitral valve replacement for infective endocarditis believed to be associated with a recent spinal surgical intervention. The patient developed haemodynamic compromise on the third day postoperatively. Computed tomography showed a splenic rupture as the cause. The patient underwent emergency radiological intervention with coil embolization avoiding the need for a splenectomy and was discharged home.

Although immunohistochemistry (IHC) along with molecular tests has been investigated in ameloblastoma for BRAF V600E detection, VE1 IHC has not been studied in odontogenic carcinomas (OCs) and benign mixed epithelial and mesenchymal odontogenic tumours (BMOTs). Here, we performed BRAF V600E mutation analysis, examined the expression pattern of VE1 IHC, and comparatively evaluated the performance of two VE1 antibodies in ameloblastomas, OCs and BMOTs.

BRAF V600E detection was performed using Sanger sequencing in a total of 47 odontogenic tumours 28 ameloblastomas, 6 OCs and 13 BMOTs. VE1 IHC was conducted using two different antibodies (IHC-A and IHC-V), and their performance was analysed by calculating the sensitivity and specificity compared with sequencing.

BRAF V600E mutations were identified in 24/28 (85.7%) ameloblastomas, 2/5 (40.0%) ameloblastic carcinomas (ACs), 3/7 (42.9%) ameloblastic fibromas and 1/2 (50.0%) ameloblastic fibro-odontomas. In the presence of the mutation, VE1 showed diffuse cytbut low sensitivity of VE1 IHC, molecular tests should be performed to determine the presence of BRAF V600E mutations in odontogenic tumours.We present an unusual case of atrial septal defect and ventricular septal defect with a vascular ring formed by a right-sided aortic arch with an aberrant left subclavian artery that gave rise to a patent ductus arteriosus connecting to the main pulmonary artery. We performed a single-stage repair of the intracardiac defects and division of vascular ring with a sternotomy instead of the traditionally practiced dual approach. This included division and reimplantation of the aberrant left subclavian artery to the left carotid artery after transection. This approach has not been described so far.

The present study aimed to analyze the histopathologic aspects of cases diagnosed as chronic hyperplastic candidiasis (CHC) in an oral pathology service, pointing out the most important features found.

All cases histopathologically diagnosed as CHC between 2002 and 2018 were retrieved from the files of the service. Data of the patients and the lesions were collected. Histopathological analysis was performed to evaluate the microscopic characteristics and the amount of Candida present.

Thirty-six cases of CHC were retrieved. Women were more affected and there was a predilection for Whites. Most lesions appeared as a nodule or a white plaque, asymptomatic, on the tongue or buccal mucosa. Histopathologically, statistical significance was noted for the presence of epithelial hyperplasia, exocytosis, and mononuclear inflammatory infiltrate. Interestingly, only the association between dysplasia and the amount of fungus was noted.

CHC appears to be a distinct entity presenting typical histopathologic aspects. CHC might even show epithelial dysplasia. In those cases, the presence of a large amount of Candida together with other histopathological features should lead to the diagnosis of CHC and subsequent treatment. However, close follow up is important.
