Randomized Controlled Trial Multicenter Study
Antihypertensive efficacy and safety of manidipine versus amlodipine in elderly subjects with isolated systolic hypertension: MAISH study.
Isolated systolic hypertension (ISH) affects 10-20% of the elderly population and is strongly related to the risk of cardiovascular events. Elevated systolic BP values are primarily caused by reduced large vessel compliance with a consequent increase in total peripheral resistance. Vasodilating drugs, such as calcium channel antagonists, have proven to be effective in controlling ISH in elderly patients. This study set out to compare the antihypertensive efficacy and safety of two different calcium channel antagonists, manidipine and amlodipine, administered once daily in elderly subjects with ISH. ⋯ In elderly patients with ISH, treatment with manidipine for 12 weeks was well tolerated and effective and the antihypertensive effects obtained with manidipine were the same as those obtained with amlodipine.

Randomized Controlled Trial Multicenter Study Comparative Study
Double-blind comparison of escitalopram and duloxetine in the acute treatment of major depressive disorder.
Escitalopram is the most selective serotonin reuptake inhibitor antidepressant; in contrast, duloxetine inhibits both serotonin and norepinephrine reuptake. Double-blind comparison studies may help guide treatment decisions by revealing the relative benefits of different therapeutic approaches. This study evaluated the efficacy and safety of escitalopram versus duloxetine in the acute treatment of patients with moderate to severe major depressive disorder. ⋯ These findings suggest that escitalopram is better tolerated and at least as effective as the serotonin-norepinephrine reuptake inhibitor duloxetine in the treatment of major depressive disorder.

Randomized Controlled Trial Multicenter Study Comparative Study
A multicentre, randomised, double-blind study comparing the efficacy and tolerability of intramuscular dexketoprofen versus diclofenac in the symptomatic treatment of acute low back pain.
Low back pain is an important medical problem in Western industrialised countries. NSAIDs are one of the main options for symptomatic pain relief in the early management of this painful condition. Dexketoprofen is an NSAID belonging to the arylpropionic acid group that has demonstrated good analgesic efficacy and a good safety profile in different acute and chronic painful conditions. ⋯ From the results of this study it can be concluded that dexketoprofen 50mg administered twice daily intramuscularly provides a clinically relevant analgesic effect with good tolerability after single and repeated doses in patients with acute severe low back pain.

Multicenter Study
Absorption of fentanyl from fentanyl buccal tablet in cancer patients with or without oral mucositis: a pilot study.
Patients with cancer, particularly those undergoing chemotherapy or radiotherapy, may develop oral mucositis. This is the first study to investigate the absorption profile of fentanyl buccal tablet (FBT) - an effervescent formulation of fentanyl indicated for the management of breakthrough pain in opioid-tolerant cancer patients - in patients with or without oral mucositis. ⋯ The absorption profile of a single dose of FBT 200 microg was similar in patients with or without mild oral mucositis. The compound was generally well tolerated.

The superior vena cava (SVC) syndrome occurs when obstruction of this vessel interrupts venous return of blood from the head, upper extremities and thorax to the right atrium. Most cases of SVC syndrome result from neoplasia, especially from lung cancer, but other non-cancer-associated causes may include fibrosis caused by radiotherapy, collagen-vascular diseases, arteriovenous shunts or thrombosis as a complication of use of central venous catheters or devices. We report here the case of a 60-year-old woman with non-small cell lung cancer who was treated, after three lines of chemotherapy, with the epidermal growth factor receptor inhibitor erlotinib and subsequently presented to the hospital with abrupt onset of syncope, shortness of breath and cyanosis (face, neck and trunk). ⋯ The patient was treated with the systemic thrombolytic agent urokinase, with resolution of the clinical picture and no bleeding complications. The possible pathogenetic causes of thrombosis of the brachiocephalic veins and SVC syndrome in this case are discussed. It is possible that acute thrombosis may be associated with erlotinib use, even if it is likely that cancer may be the main cause of the thrombotic complication.
