The purpose of this work is to document whether prescription opioid medications used for pain enhanced or worsened pain syndromes from medical conditions in patients who received a diagnosis of prescription opioid dependence as determined by a diagnosis by Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria. Further, whether detoxification improved or worsened pain perceptions and self-reports in patients who chronically administered prescription opioid medications. Our study consisted of a retrospective sample of patients taken from the Addiction Treatment Unit at St Lawrence Hospital in Lansing, MI. ⋯ The detoxification period extended to an average of 5 days. Whereas oxycodone CR (OxyContin) produced higher levels of self-reported pain at admission than at discharge, and these patients experienced significant levels of pain reduction with decremental opioid doses as with other opioid medications. Patients with a DSM-IV diagnosis of prescription opioid dependence reported (self) less pain with detoxification and abstinence from the opioid medications.

We evaluated efficacy and toxicity profiles of fludarabine, Ara-C, idarubicin, and G-CSF (Ida-FLAG) combination chemotherapy in 56 refractory and/or relapsed acute leukemia patients. Patients were treated with fludarabine phosphate 25 mg/m2/d (d1-5), Ara-C 2 g/m2/d (d1-5), idarubicin 12 mg/m2/d (d1-3), G-CSF was given subcutaneously from sixth day until absolute neutrophil count (ANC) >500/microL. One third of the acute myeloblastic leukemia (AML) and 45% of acute lymphoblastic leukemia (ALL) cases were primary refractory disease. ⋯ The rest of the patients died. In conclusion, Ida-FLAG is a good choice in cases with refractory/relapsing acute leukemia for salvage chemotherapy. High efficacy and a low-toxicity profile are preferable properties of this regimen, and this regimen has been found to be useful for cytoreduction, especially in candidates for allo-SCT.

Sildenafil is widely used as a primary pharmacological treatment of erectile dysfunction in men with and without underlying cardiovascular disease. Although initial reports of adverse cardiac events were reported soon after Food and Drug Administration approval of this agent, a large body of data suggests that sildenafil does not significantly increase the risk of nonfatal myocardial infarction, stroke, or cardiovascular deaths in patients with preexisting ischemic heart disease. ⋯ The patient had presented with chest pain syndrome and borderline elevation of serum troponin I levels 1 week before sildenafil use, and a coronary angiogram had demonstrated normal coronary arteries. This case emphasizes the potential of precipitating coronary thrombosis in patients with unstable plaque after sildenafil use, even in patients with angiographically normal coronary arteries.

We investigated the prevalence of sinus rhythm at long-term follow-up of 35 patients with atrial fibrillation who had an intraoperative radiofrequency maze procedure at the time of valve surgery or coronary artery bypass grafting. The 35 patients included 22 men and 13 women, mean age 71+/-10 years. ⋯ At 29-month follow-up, 28 of 31 in-hospital survivors (90%) were alive. Of the 28 survivors, 18 (64%) were in sinus rhythm.

Latin America in the past two decades has increasingly become a significant contributor of clinical research. The future capacity of clinical and specifically cardiovascular research has the potential to positively affect human health in the region and foster economic growth. However, the challenges of conducting clinical research in Latin America include a need for logistical support from local governments, continued commitment to education of physicians and ethics committees, and creation of oversight bodies to guarantee the highest quality of research. ⋯ The region offers many opportunities for clinical research including large treatment-naive patient populations and most importantly motivated investigators capable of producing high-quality results. Strategies to foster clinical research in Latin America must be based on development of a positive regulatory environment, leveraged protection of intellectual property, creation of alliances between private and public sectors with incentives for investment in science and technology, and finally focus on areas of clinical expertise such as cardiovascular disease, epidemiology, gastroenterology, and infectious diseases. Fostering the creation of research alliances across and between continents will help in establishing the supportive environment for dissemination of important ethical clinical research in the region.
