Plasmablastic lymphoma (PBL) is an aggressive non-Hodgkin lymphoma associated with HIV infection and immunodeficiency. However, PBL can also be seen immunocompetent individuals in recent studies. PBL was characterized by distinct clinical and pathological features, such as plasmablastic morphology and universal expression of plasma cell markers. The clinicopathologic features were different between HIV-negative and HIV-positive patients. Gene expression analysis identified the unique molecular feature in PBL, including frequent c- MYC rearrangement and downregulation of BCR signaling pathway...

OBJECTIVES: We aim to develop a deep learning model based on a convolutional neural network (CNN) combined with a classification algorithm (CA) to assist dentists in quickly and accurately diagnosing the stage of periodontitis. MATERIALS AND METHODS: Periapical radiographs (PERs) and clinical data were collected. The CNNs including Alexnet, VGG16, and ResNet18 were trained on PER to establish the PER-CNN models for no periodontal bone loss (PBL) and PBL. The CAs including random forest (RF), support vector machine (SVM), naive Bayes (NB), logistic regression (LR), and k-nearest neighbor (KNN) were added to the PER-CNN model for control, stage I, stage II and stage III/IV periodontitis...

BACKGROUND: Recently, there has been a concerted effort within medical schools to depart from conventional lecture-based learning approaches to alternative teaching methods such as team-based learning (TBL) and problem-based learning (PBL), with the aim of enhancing both student engagement and instructional efficacy. Despite this shift, a comprehensive review that directly compares the impacts of PBL and TBL methods in medical education is lacking. This study seeks to address this gap by conducting a meta-analysis that compares the effects of TBL and PBL in the context of medical education...

Extranodal marginal zone lymphoma (EMZL) is a low-grade subtype of B-cell non-Hodgkin lymphoma that can affect any mucosal tissue, most commonly the GI tract. Primary involvement of the breast, known as primary breast lymphoma (PBL), is a very rare manifestation. We report an unusual case of a 65-year-old woman with primary breast EMZL presenting as calcifications discovered during screening mammography. This represents an exceedingly atypical appearance of primary breast lymphoma that is rarely described in the literature...

The changing landscape of medical education has made small-group discussions crucial components. These sessions, including problem-based learning (PBL), case-based learning (CBL), and team-based learning (TBL), revolutionize learning by fostering active participation, critical thinking, and practical skills application. They bridge theory with practice, preparing future healthcare professionals for the dynamic challenges of modern healthcare. Despite their transformative potential, there are challenges in faculty preparation, resource allocation, and effective evaluation...

The diagnosis of primary bone lymphoma (PBL) of the spine is challenging due to its nonspecific symptoms and radiographic features. This report details the case of an 81-year-old female who presented with lower limb weakness and thoracic pain, consequent to a vertebral pathological fracture and spinal cord compression. The initial surgical intervention revealed granulomas with caseous necrosis; however, a definitive diagnosis remained elusive. Following a third surgical procedure and further histopathological examination, the patient was finally diagnosed with diffuse large B-cell lymphoma...

Plasmablastic lymphoma (PBL) is an uncommon and aggressive large B-cell lymphoma commonly diagnosed in human immunodeficiency virus-positive patients. Though the oral cavity is a common site for PBL, this condition is not commonly reported in the literature as an oral manifestation. Most oral PBLs presented as an asymptomatic swelling, frequently associated with ulcerations and bleeding. No standard treatment is yet advocated for oral PBL. Five-year survival rate was recorded not more than 33.5%. This presentation emphasizes on oral manifestation of plasmablastic lymphoma (PBL) as a rare entity, which was provisionally diagnosed for carcinoma (CA) oral cavity...

BACKGROUND: Primary bone lymphoma (PBL) is a rare form of extra nodal non-Hodgkin's lymphoma (NHL). CASE DESCRIPTION: We describe a 39-year-old-male with no medical history who presented with unilateral facial swelling following a tooth extraction. Initial diagnoses after various presentations over the course of three weeks, based on inflammatory and infectious aetiologies. However, the patient was ultimately diagnosed with diffuse large B-cell lymphoma. DISCUSSION: Symptoms of PBL are very similar to inflammatory and infectious diseases of the bone, such as osteomyelitis or osteonecrosis...

Cancer immunotherapy is expected to achieve tumor treatment mainly by stimulating the patient's own immune system to kill tumor cells. However, the low immunogenicity of the tumor and the poor efficiency of tumor antigen presentation result in a variety of solid tumors that do not respond to immunotherapy. Herein, we designed a proton-gradient-driven porphyrin-based liposome (PBL) with highly efficient Toll-like receptor 7 (TLR7) agonist (imiquimod, R837) encapsulation (R837@PBL). R837@PBL rapidly released R837 in the acid microenvironment to activate the TLR in the endosome inner membrane to promote bone-marrow-derived dendritic cell maturation and enhance antigen presentation...

Introduction As medical knowledge, technology, and healthcare delivery continue to evolve, it is critical that upcoming healthcare workers possess the skills and information needed to ensure optimal patient care. Numerous studies indicate that students achieve better learning outcomes through active practice rather than solely relying on theoretical knowledge. The average human attention span is only 8.25 seconds, so an effective teaching program should employ various modes and techniques to ensure that students remain involved and interested...
