INTRODUCTION: Successful outcomes in dental management for patients with inherited bleeding disorders require close collaboration between haematology teams and dentists. AIM: To review outcomes of an interdisciplinary pathway for dental procedures by assessing adequacy and appropriateness of haemostatic management. METHODS: Two hundred dental procedures in 30 patients with inherited bleeding disorders were included. A Dental Bleeding Risk Assessment and Treatment Tool (DeBRATT) was developed to identify four categories of bleeding risk (no risk, low, moderate and high risk of bleeding) in relation to the severity of the bleeding disorder and the invasiveness of dental procedure...

Paraneoplastic cerebellar degeneration (PCD) is one of the most common paraneoplastic neurological syndromes characterized by the rapid development of severe cerebellar ataxia. In this report, a 23-year-old female with noticeable dizziness and gait instability was described. The enhanced CT scanning suggested the presence of a pelvic tumor. Then, PCD was established. Postoperative pathological result defined it as a liposarcoma (LS) with dedifferentiation. Interestingly, clinical symptoms disappeared after the surgical removal of the pelvic tumor...

Transient Receptor Potential Vanilloid, member 1 (TRPV1), is a non-selective cation channel belonging to the transient receptor potential (TRP) family of ion channels. It occurs in the peripheral and central nervous system, activated by a variety of exogenous and endogenous stimuli, thus playing a key role in transmission of pain. This has been a target for chronic pain since more than a decade and a number of antagonists that progressed into clinical trials have failed due to the unexpected side effect of core body temperature rise, thus halting progress in this field...

Tuberous sclerosis (TSC) is an inherited tumor syndrome caused by mutations in TSC1 or TSC2 that lead to aberrant activation of mTOR and development of tumors in multiple organs including the kidneys. The mTOR inhibitors rapamycin and everolimus (rapalogs) have demonstrated clinical efficacy in treating TSC-associated tumors including renal angiomyolipomas. However, tumor responses are usually only partial, and regrowth occurs after drug withdrawal. TSC-associated tumors are highly vascular, and TSC patients with renal angiomyolipomas have elevated levels of circulating vascular endothelial growth factor (VEGF) A and VEGFD...

The IFN-γ production is crucial for NK cell-mediated lysis of cancer cells. Thus increasing the IFN-γ production by NK cells may be an ideal strategy to improve their tumoricidal effect. Since the focus on new drug development has shifted towards natural products, limited information is out there about natural products that enhance the IFN-γ production by NK cells. In this study, through a high-throughput screening, we have identified a natural product ingenol 3,20 dibenzoate (IDB), an activator of tumor suppressor protein kinase C (PKC) isozymes, could increase the IFN-γ production and degranulation by NK cells, especially when NK cells were stimulated by non-small lung cancer (NSCLC) cells...

The periosteum plays a critical role in bone homeostasis and regeneration. It contains a vascular component that provides vital blood supply to the cortical bone and an osteogenic niche that acts as a source of bone-forming cells. Periosteal grafts have shown promise in the regeneration of critical size defects, however their limited availability restricts their widespread clinical application. Only a small number of tissue-engineered periosteum constructs (TEPCs) have been reported in the literature. A current challenge in the development of appropriate TEPCs is a lack of pre-clinical models in which they can reliably be evaluated...

The articular cartilage and subchondral bone may have potential crosstalk in the development and progression of osteoarthritis (OA). Strontium ranelate (SrR) has the ability to dissociate the bone remodeling process and to change the balance between bone resorption and bone formation. Its effect on subchondral bone makes it a potential disease- modifying osteoarthritis drug (DMOAD) in the treatment of OA. The aim of the current review is to summarize up-to-date pharmacological and clinical data of SrR for OA treatment...

Proton pump inhibitors are among the most commonly prescribed classes of drugs and their use is increasing, in particular for long term treatment, often being over-prescribed and used for inappropriate conditions. In recent years, considerable attention has been directed towards a wide range of adverse effects, and even when a potential underlying biological mechanism is plausible, the clinical evidence of the adverse effect is often weak. Several long term side effects have been investigated ranging from interaction with other drugs, increased risk of infection, reduced intestinal absorption of vitamins and minerals, and more recently kidney damage and dementia...

Pathogenic streptococcal species are responsible for some of the most lethal and prevalent animal and human infections. Previous reports have identified a candidate pathogenicity island (PAI) in two highly virulent clinical isolates of Streptococcus suis type 2 (SS2), a causative agent of high-mortality streptococcal toxic shock syndrome (STSS). This PAI contains a Type-IVC secretion system C subgroup (Type-IVC secretion system) that is involved in the secretion of unknown pathogenic effectors that are responsible for STSS caused by highly virulent strains of SS2...

In contrast to the rapid development of the horse husbandry in China, the ability of horse veterinarians to diagnose diseases has not been improved and only a few domain experts have considerable expertise. At present, many expert systems have been developed for diseases diagnosis, but few for horse diseases diagnosis have been studied in depth. This paper presents the design and development of a computer-aided expert system for diagnosing horse diseases. We suggest an approach for diagnosis of horse diseases based on the analysis of diagnostic characteristics and the experiential knowledge of domain experts...

GOAL: Accurate determination of the epileptogenic focus is of paramount diagnostic and therapeutic importance in epilepsy. The current gold standard for focus localization is from ictal (seizure) onset and thus requires the occurrence and recording of multiple typical seizures of a patient. Localization of the focus from seizure-free (interictal) periods remains a challenging problem, especially in the absence of interictal epileptiform activity. METHODS: By exploring the concept of effective inflow, we developed a focus localization algorithm (FLA) based on directed connectivity between brain sites...

Purpose To develop a method to incorporate the propagation of contrast material into computational anthropomorphic phantoms for estimation of organ dose at computed tomography (CT). Materials and Methods A patient-specific physiologically based pharmacokinetic (PBPK) model of the human cardiovascular system was incorporated into 58 extended cardiac-torso (XCAT) patient phantoms. The PBPK model comprised compartmental models of vessels and organs unique to each XCAT model. For typical injection protocols, the dynamics of the contrast material in the body were described according to a series of patient-specific iodine mass-balance differential equations, the solutions to which provided the contrast material concentration time curves for each compartment...

Cardiotoxicity is a common complication that may compromise the clinical effectiveness of anticancer therapy. The current standard for monitoring cardiac function detects cardiotoxicity only when a functional impairment has already occurred, not allowing for any early preventive strategy. Areas covered: A novel approach, based on the use of biomarkers has recently emerged, resulting in a very effective tool for early, real-time identification, and monitoring of cardiotoxicity. In particular, cardiac troponin elevation during chemotherapy allows to identify patients more prone to develop myocardial dysfunction and cardiac events...
