REVIEW
E Carlos Rodriguez-Merchan
Musculo-skeletal pain treatment is inadequate in many haemophilic patients. Analgesics are used only by 36% of adult patients. FVIII/FIX intravenous infusion is mainly used to lessen pain, followed in frequency by usage of NSAIDS (primarily COX-2 inhibitors). In about 30% of patients, pain continues after infusion of F VIII/IX. In acute haemarthroses pain treatment must continue until total disappearance (checked by ultrasonography) and include haematologic treatment, short-term rest of the involved joint, cryotherapy, joint aspiration and analgesic medication (paracetamol in mild pain, metamizole for more intense pain, and in a few precise patients, soft opioids such as codeine or tramadol)...

BACKGROUND: Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs), e.g. sofosbuvir, are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may eradicate hepatitis C virus (HCV) from the blood (sustained virological response). Sustained virological response (SVR) is used by investigators and regulatory agencies as a surrogate outcome for morbidity and mortality, based solely on observational evidence...

Olayide A Arodola, Mahmoud Es Soliman
The pharmaceutical industry is progressively operating in an era where development costs are constantly under pressure, higher percentages of drugs are demanded, and the drug-discovery process is a trial-and-error run. The profit that flows in with the discovery of new drugs has always been the motivation for the industry to keep up the pace and keep abreast with the endless demand for medicines. The process of finding a molecule that binds to the target protein using in silico tools has made computational chemistry a valuable tool in drug discovery in both academic research and pharmaceutical industry...

Mrwan Alayed, M Jamal Deen
Diffuse optical spectroscopy (DOS) and diffuse optical imaging (DOI) are emerging non-invasive imaging modalities that have wide spread potential applications in many fields, particularly for structural and functional imaging in medicine. In this article, we review time-resolved diffuse optical imaging (TR-DOI) systems using solid-state detectors with a special focus on Single-Photon Avalanche Diodes (SPADs) and Silicon Photomultipliers (SiPMs). These TR-DOI systems can be categorized into two types based on the operation mode of the detector (free-running or time-gated)...

Tony Badrick, Peter Graham
Internal Quality Control and External Quality Assurance are separate but related processes that have developed independently in laboratory medicine over many years. They have different sample frequencies, statistical interpretations and immediacy. Both processes have evolved absorbing new understandings of the concept of laboratory error, sample material matrix and assay capability. However, we do not believe at the coalface that either process has led to much improvement in patient outcomes recently. It is the increasing reliability and automation of analytical platforms along with improved stability of reagents that has reduced systematic and random error, which in turn has minimised the risk of running less frequent IQC...

Xavier Symons
The doctrine of double effect (DDE) is a principle of crucial importance in law and medicine. In medicine, the principle is generally accepted to apply in cases where the treatment necessary to relieve pain and physical suffering runs the risk of hastening the patient's death. More controversially, it has also been used as a justification for withdrawal of treatment from living individuals and physician-assisted suicide. In this paper, I will critique the findings of the controversial Victorian Civil and Administrative Tribunal (VCAT) hearing Syme vs the Medical Board of Australia In that hearing, Dr Rodney Syme, a urologist and euthanasia advocate, was defending his practice of prescribing barbiturates to terminally ill patients...

Terrorist attacks or amok runs may cause "threatening situations" for emergency medical services (EMS), fire fighters and physicians. Cooperation with the police is of paramount importance. In order to minimize the risk to rescue personnel and affected persons, emergency medical care has to follow tactical principles. So, the strategy in such "threatening situations" is "Stop the bleeding and clear the scene". The police define three areas of danger: unsafe, partly safe and secure. Medical care in these areas follows the concept of Tactical Combat Casualty Care...

BACKGROUND: Ovarian carcinoma is the most lethal cancer among all gynaecological malignancies. One of the most chemotherapy drugs used for ovarian cancer is paclitaxel which induces apoptosis. Paclitaxel has been used for many years. Similar to the most cancers this responds to chemotherapy initially but in a long run, drug resistance happens which fails the treatment procedure. Combination of chemotherapy drugs has been suggested to deal with this issue. Silibinin, a plant extraction, has been used from ancient time in traditional medicine and identified to have powerful antioxidant activity...

Batches of pharmaceuticals are sometimes recalled from the market when a safety issue or a defect is detected in specific production runs of a drug. Such problems are usually detected when patients or healthcare providers report abnormalities to medical authorities. Here, we test the hypothesis that defective production lots can be detected earlier by monitoring queries to Internet search engines. We extracted queries from the USA to the Bing search engine, which mentioned one of the 5195 pharmaceutical drugs during 2015 and all recall notifications issued by the Food and Drug Administration (FDA) during that year...
