OBJECTIVE: To provide veterinarians with updated radiographic descriptions of select radiolucent foreign material in a simulated gastrointestinal environment. SAMPLE: 368 veterinarian respondents from the US. METHODS: An online survey was administered between June 18, 2023, and July 2, 2023, through a private veterinarian-based social media group. Representative commonly ingested foreign bodies were radiographed surrounded by air and water to simulate being within the gastrointestinal tract...

Foreign body ingestion is a common clinical occurrence worldwide, with high morbidity in the pediatric population and in adult patients with intentional attempts. Coins and button battery ingestions are more common among children. Bone impaction and swallowed dentures are usually seen in older adults. While most ingested foreign bodies pass through the gastrointestinal tract spontaneously with no complications, some require endoscopic and/or surgical intervention. Complications such as pharyngoesophageal ulceration, perforation, stricture, and deep neck infection can develop without timely diagnosis and management...

BACKGROUND AND OBJECTIVE: Medical thoracoscopy (MT) is an endoscopic technique performed by interventional pulmonologists with a favorable safety profile and few contraindications, providing diagnostic and therapeutic intervention in a single sitting. This narrative review was designed to summarize the therapeutic role of MT based on the latest results from the available literature. METHODS: Pertinent literature published in English, relative to human studies, between 2010-2022 was searched in Medline/PubMed and Cochrane databases...

Host recognition and immune-mediated foreign body response (FBR) to biomaterials can adversely affect the functionality of implanted materials. To identify key targets underlying the generation of FBR, here we perform analysis of microRNAs (miR) and mRNAs responses to implanted biomaterials. We found that (a) miR-146a levels inversely affect macrophage accumulation, foreign body giant cell (FBGC) formation, and fibrosis in a murine implant model; (b) macrophage-derived miR-146a is a crucial regulator of the FBR and FBGC formation, as confirmed by global and cell-specific knockout of miR-146a; (c) miR-146a modulates genes related to inflammation, fibrosis, and mechanosensing; (d) miR-146a modulates tissue stiffness near the implant during FBR; and (e) miR-146a is linked to F-actin production and cellular traction force induction, which are vital for FBGC formation...

KEY CLINICAL MESSAGE: Foreign body ingestion is common in pediatric age group however can be found in any age group with intellectual disability and neurodevelopmental delay. There is usually a delay in presentation and interventions following foreign body ingestion in patients with neurodevelopmental delay, leading to increased morbidity, mortality, and complications owing to inability of such patients giving relevant history. Most ingested foreign bodies naturally pass through the digestive tract without untoward effects...

INTRODUCTION AND IMPORTANCE: Bladder stones, although rare in a healthy bladder, can emerge due to various factors, including obstructions in urinary flow, recurrent infections, and foreign bodies. Intrauterine contraceptive devices (IUCDs) are known for their potential to migrate from the uterine cavity, leading to unusual complications such as bladder stone formation. CASE PRESENTATION: A 52-year-old woman, previously treated for a complicated urinary tract infection, presented with intermittent lower abdominal pain, dysuria, and hematuria...

BACKGROUND: Ghost cell odontogenic carcinoma (GCOC) is a rare malignancy characterized by the presence of ghost cells, preferably in the maxilla. Only slightly more than 50 case reports of GCOC have been documented to date. Due to the rarity of this tumor and its nonspecific clinical criteria, there is a heightened risk of misdiagnosis in clinical examination, imaging findings, and pathology interpretation. CASE PRESENTATION: A 50-year-old male patient presented to the hospital due to experiencing pain in his lower front teeth while eating for the past 2 months...

Catheter-induced thrombosis is a major contributor to infectious and mechanical complications of biomaterials that lead to device failure. Herein, a dual functional submicron textured nitric oxide (NO)-releasing catheter was developed. The hemocompatibility and antithrombotic activity of vascular catheters were evaluated in both 20 h in vitro blood loop and 7 d in vivo rabbit model. Surface characterization assessments via atomic force microscopy show the durability of the submicron pattern after incorporation of NO donor S-nitroso-N-acetylpenicillamine (SNAP)...

To our knowledge, this is a unique report of intraoperative magnetic resonance imaging (iMRI) of an intracranial cottonoid. The current literature describes images of cottonoids as a post-operative finding in the setting of an unintentionally retained foreign body; however, the iMRI images we present are important as the use of iMRI in the resection of complex tumors and epilepsy foci increases. This series of images was obtained during a craniotomy for tumor resection of a patient with dysembryoplastic neuroepithelial tumor...

BACKGROUND: A body of research from around the world has reported positive effects of bilingualism on cognitive ageing and dementia. However, little is known about whether foreign language learning could be applied as an intervention for people already living with dementia. Yet, before it is possible to determine the efficacy of language courses as an intervention for people living with dementia (PLWD), it is necessary to establish whether such an intervention is feasible. Our study explored this possibility...

OBJECTIVES: The aim of this narrative review is to describe the emerging evidence concerning etiological factors and pathophysiological mechanisms involved in peri-implant inflammatory diseases. MATERIAL AND METHODS: An electronic search for articles published until November 2022 was conducted in MEDLINE by three independent reviewers to identify manuscripts reporting data on etiological factors and pathophysiological mechanisms associated with peri-implant diseases...

Coevolution of hosts and their parasites has shaped heterogeneity of effector hemocyte types, providing immune defense reactions with variable effectiveness. In this work, we characterize hemocytes of Drosophila willistoni , a species that has evolved a cellular immune system with extensive variation and a high degree of plasticity. Monoclonal antibodies were raised and used in indirect immunofluorescence experiments to characterize hemocyte subpopulations, follow their functional features and differentiation...

Macrophages play a crucial role in host response and wound healing, with M2 polarization contributing to the reduction of foreign-body reactions induced by the implantation of biomaterials and promoting tissue regeneration. Electrical stimulation (ES) and micropatterned substrates have a significant impact on the macrophage polarization. However, there is currently a lack of well-established cell culture platforms for studying the synergistic effects of these two factors. In this study, we prepared a graphene free-standing substrate with 20 μm microgrooves using capillary forces induced by water evaporation...

The inflammatory response is a key factor affecting tissue regeneration. Inspired by the immunomodulatory role of spermidine, an injectable double network hydrogel functionalized with spermidine (DN-SPD) is developed, where the first and second networks are formed by dynamic imine bonds and non-dynamic photo-crosslinked bonds respectively. The single network hydrogel before photo-crosslinking exhibits excellent injectability and thus can be printed and photo-crosslinked in situ to form double network hydrogels...

INTRODUCTION: This article discusses a case study involving a unique occurrence of a hepatic abscess caused by the presence of an ingested foreign body. Hepatic abscesses, characterized by pus accumulation within liver tissue, often result from various infections, with some cases having unidentified origins. CASE PRESENTATION: This study focuses on a 75-year-old man who presented at an emergency department with persistent pain in the right upper abdomen and fever for ten days...

The most common reasons for emergency visits to a maxillofacial surgery department are infections and trauma to the mouth, jaw and face. Many infections of the facial area are of odontogenic origin. Furthermore, contaminated wounds or foreign bodies can also cause a facial infection such as an abscess. Therefore, in some cases, initial trauma and subsequent wound infection in the facial area are closely related. The following case report describes the rare cause of a temporal abscess caused by an infected key bit after bicycle accident two weeks after the initial trauma...
