BACKGROUND: Complex regional pain syndrome type I (CRPS-I), also called algodystrophy, is a complex syndrome characterized by limb pain, edema, allodynia, hyperalgesia and functional impairment of bone with a similar clinical picture of osteoporosis, including an increased release of various pro-inflammatory neuropeptides and cytokines. Several treatments have been proposed for CRPS-I, but due to the poor outcome of conventional drugs and the invasiveness of some techniques, expectations are now directed towards new resources that could be more effective and less invasive...

Drug-induced liver injury is one of the main reasons for acute liver failure. We report the case of a young patient who experienced a drug-induced liver injury resulting in life-threatening acute liver failure after treatment with different antibiotics (amoxicillin, ciprofloxacin, cefazolin, clindamycin) and acetaminophen, or a combination of these drugs. Moreover, we provide an overview of the hepatotoxic potential of these drugs.

Although targeted inhibition of oncogenic kinase drivers has achieved remarkable patient responses in many cancers, the development of resistance has remained a significant challenge. Numerous mechanisms have been identified, including the acquisition of gatekeeper mutations, activating pathway mutations, and copy number loss or gain of the driver or alternate nodes. These changes have prompted the development of kinase inhibitors with increased selectivity, use of second-line therapeutics to overcome primary resistance, and combination treatment to forestall resistance...

Antibiotics methymycin (MTM) and pikromycin (PKM), co-produced by Streptomyces venezuelae, represent minimalist macrolide protein synthesis inhibitors. Unlike other macrolides, which carry several side chains, a single desosamine sugar is attached to the macrolactone ring of MTM and PKM. In addition, the macrolactone scaffold of MTM is smaller than in other macrolides. The unusual structure of MTM and PKM and their simultaneous secretion by S. venezuelae bring about the possibility that two compounds would bind to distinct ribosomal sites...

Sorafenib, an orally available kinase inhibitor, is the standard first-line systemic drug for advanced hepatocellular carcinoma (HCC), and it exerts potent inhibitory activity against epithelial-mesenchymal transition (EMT) and multidrug resistance (MDR) by inhibiting mitogen-activated protein kinase (MAPK) signaling in HCC. However, after long-term exposure to sorafenib, HCC cells exhibit EMT and resistance to sorafenib. The activation of AKT by sorafenib is thought to be responsible for the development of these characteristics...

BACKGROUND: The optimal transcatheter embolization strategy for patients with unresectable hepatocellular carcinoma (HCC) remains elusive. We conducted a systematic review and network meta-analysis (NMA) of different embolization options for unresectable HCC. METHODS: Medical databases were searched for randomized controlled trials evaluating bland transarterial embolization (TAE), conventional TACE, drug-eluting bead chemoembolization (DEB-TACE), or transarterial radioembolization (TARE), either alone or combined with adjuvant chemotherapy, or local liver ablation, or external radiotherapy for unresectable HCC up to June 2017...

Angiogenesis is a complex biological process that plays a relevant role in sustaining the microenvironment, growth, and metastatic potential of several tumors, including non-small cell lung cancer (NSCLC). Bevacizumab was the first angiogenesis inhibitor approved for the treatment of patients with advanced NSCLC in combination with chemotherapy; however, it was limited to patients with non-squamous histology and first-line setting. Approval was based on the results of two phase III trials (ECOG4599 and AVAIL) that demonstrated an improvement of about two months in progression-free survival (PFS) in both trials, and in the ECOG4599 trial, an improvement in overall survival (OS) also...

Oncology drug development has been increasingly shaped by molecularly targeted agents (MTAs), which often demonstrate differential effectiveness driven by the biomarker expression levels on tumors. Innovative statistical designs have been proposed to tackle this challenge, e.g., Freidlin et al (2005), Jiang et al (2007) and Freidlin et al (2010). All of these are essentially adaptive confirmatory Phase 3 designs that combine the testing of treatment effectiveness in the overall population with an alternative pathway for a more restrictive efficacy claim in a sensitive subpopulation...

Most studies on new cancer drugs are based on population-derived data, where the absence of response of a small population may pass unnoticed. Thus, individual longitudinal tracking of cells is important for the future development of efficient cancer treatments. We have used digital holographic microscopy to track individual JIMT-1 human breast cancer cells and L929 mouse fibroblast cultivated in normoxia or hypoxia. In addition, JIMT-1 cells were treated with salinomycin, a cancer stem cell targeting compound...

OBJECTIVE: To develop and test a tool to assess causality of direct and indirect adverse events associated with therapeutic interventions. The intervention was one or more drugs and/or natural health products, a device, or practice (professional delivering the intervention). METHODS: Through the assessment of causality of adverse events, we can learn about factors contributing to the harm and consider what modification may prevent its reoccurrence. Existing scales (WHO-UMC, Naranjo and Horn) were adapted to develop a tool (algorithm and table) to evaluate cases of serious harmful events reported through a national surveillance study...

An engineered metallic nanostructure is an excellent candidate for "theranosis" of cancer, having intrinsic properties of multimodal imaging and therapy. Toward this target, the development of silver-neodymium bimetallic nanoparticles (Ag-Nd BNPs) via microwave-assisted polyol synthesis is presented. The resultant Ag-Nd BNPs exhibit good monodispersity with average size of 10 nm, fluorescence in the near-infrared (NIR) region, and magnetic properties. The Ag-Nd BNPs also validate MRI, CT, and NIR trimodal imaging ability and enunciate valuable temperature response upon irradiation under a NIR laser...

Despite the progress in endovascular treatment of patients with peripheral arterial disease, restenosis remains the major drawback, especially in patients with femoropopliteal lesions. To reduce neointimal proliferation and subsequent restenosis the use of antiproliferative drug eluting devices was implemented in the endovascular treatment of femoropopliteal disease. Aiming to use the favorable effects of these antiproliferative agents and to reduce foreign body exposure in affected arteries, drug coated balloons (DCB) have been developed...

OBJECTIVE: The simultaneous recording of intracerebral EEG (stereotaxic EEG, SEEG) and magnetoencephalography (MEG) is a promising strategy that provides both local and global views on brain pathological activity. Yet, acquiring simultaneous signals poses difficult technical issues that hamper their use in clinical routine. Our objective was thus to develop a set of solutions for recording a high number of SEEG channels while preserving signal quality. APPROACH: We recorded data in a patient with drug resistant epilepsy during presurgical evaluation...

The main tackle of cancer treatment is multidrug resistance during chemotherapy. Cancer cell can evade cell death during every round of orthodox chemotherapy drugs, consequently being resistance after several rounds of standard drug treatment. One of the regimens to address this multidrug resistance problem is by drug combination. However, synthetic drugs always have problems of strong side effects and toxicity. Natural compounds deriving from traditional Chinese medicine are known to have low toxicity and genuine promising effects in reversing multidrug resistance, either induced by orthodox chemotherapeutic or targeted therapy drugs...

Chronic, degenerative diseases are often characterized by inflammation and aberrant angiogenesis. For many of these pathologies, including rheumatoid arthritis, cardiovascular and autoimmune diseases, cancer, diabetes, and obesity, current therapies have limited efficacy, thus the validation of novel (chemo)preventive and interceptive approaches, of new or repurposed agents, alone or in combination with registered drugs, are urgently required. Phytochemicals (triterpenoids, flavonoids, retinoids) and their derivatives, non-steroidal anti-inflammatory drugs (aspirin) as well as biguanides (metformin and phenformin) originally developed from phytochemical backbones, are multi-target agents showing anti-angiogenic and anti-anti-inflammatory proprieties...

BACKGROUND: Notable progress has been made in chemo- and immunotherapy of B-cell lymphomas, but less in the treatment of T-cell lymphomas. OBJECTIVE: Histone deacetylases inhibitors are a potentially useful therapeutic mean, as an epigenetic dysregulation is present in lymphomas, and especially in T-cell types. We aimed to study the progress made in this area. METHOD: A minireview was achieved using the articles published in PubMed in the last two years and the new patents made in this field...
