ReviewMethotrexate: a gold standard for treatment of rheumatoid arthritis.
Rheumatoid arthritis (RA) is a painful, debilitating disease characterized by inflammation of the joints, with the proliferation of the synovium and the progressive erosion of cartilage and bone. The treatment of RA is still unsatisfactory, but a number of powerful disease-modifying antirheumatic drugs have become available, such as methotrexate (MTX). Even in the current era of biological targeted therapies, MTX remains the initial preferred antirheumatic drug and is considered to be the gold standard for treatment of RA. ⋯ In this review, the authors aim to summarize the research done in the field of drug delivery systems of MTX according to its routes of administration for treatment of RA. The last part of the review addresses combination therapy with MTX and future direction in the drug delivery of MTX. This review also provides the reader with a general overview of RA and its therapeutic strategies with respect of MTX, which may bring uniformity in medical practice for effective management of RA.

Multicenter Study Clinical TrialPharmacokinetics of oxycodone after intravenous and subcutaneous administration in Japanese patients with cancer pain.
ABSTRACT In Japan, Oxycodone hydrochloride injection formulation has been approved in 2012. However, its pharmacokinetics has been poorly studied. The aim of this study is to evaluate the pharmacokinetics of oxycodone after intravenous and subcutaneous administration of oxycodone hydrochloride injection in Japanese patients with cancer pain. ⋯ The estimated geometric mean clearance (CL) of oxycodone was 24.3 L per hour after constant intravenous infusion and 29.5 L per hour after constant subcutaneous infusion, respectively. Population pharmacokinetic analysis indicated that body surface area was the influencing factor on CL and there were no pharmacokinetic differences for CL between intravenous and subcutaneous infusion. These results provide important information for the clinical use of oxycodone injection.

Case ReportsAuditory symptoms as an unrecognized manifestation of opioid toxicity: two case reports.
Neuropsychiatric and gastrointestinal side effects of opioids are well documented, but self-reported hearing disturbance from opioids is often unrecognized. Two cases are presented illustrating a possible association between auditory symptoms and opioid toxicity. Possible mechanisms are discussed.

Assessment of pain and other symptoms in Mexican patients with advanced illness.
Palliative care is an approach that improves the quality of life of patients and their families facing the problem associated with life-threatening illness, through the prevention and relief of suffering by means of early identification and impeccable assessment and treatment of pain and other problems, physical, psychosocial, and spiritual. During this stage, several symptoms appear and contribute to a decrement in the quality of life. We performed a retrospective study evaluating medical records of terminally ill patients who attended a specialized pain and palliative medicine service. ⋯ Physicians trained in pain and palliative medicine managed those symptoms, and we observed that symptoms maintained the same intensity. There is the possibility that the intervention made by those clinicians modified the symptomatic outcome in those patients. Evaluation of effective protocols for symptom management at the end of life is needed.
