Sea level rise can severely reduce biodiversity and community net production on rocky shores.

Sea level rise (SLR), driven by anthropogenic climate change, can be a major threat to coastal ecosystems. Among the most biologically diverse but SLR-threatened coastal ecosystems are rocky shores, especially in regions with a small tidal range. Nonetheless, the impacts of SLR on rocky shore biodiversity, community structure and ecosystem functions have rarely been studied.

The Temporal Dynamics of Coastal Phytoplankton and Bacterioplankton in the Eastern Mediterranean Sea.

This study considers variability in phytoplankton and heterotrophic bacterial abundances and production rates, in one of the most oligotrophic marine regions in the world-the Levantine Basin. The temporal dynamics of these planktonic groups were studied in the coastal waters of the southeastern Mediterranean Sea approximately every two weeks for a total of two years. Heterotrophic bacteria were abundant mostly during late summer and midwinter, and were positively correlated with bacterial production and with N2 fixation.

Burning mouth syndrome: will better understanding yield better management?

"Burning mouth syndrome" (BMS) refers to a chronic orofacial pain disorder usually unaccompanied by mucosal lesions or other clinical signs of organic disease. BMS is typically characterized by a continuous, spontaneous, and often intense burning sensation as if the mouth or tongue were scalded or on fire. Burning mouth syndrome is a relatively common condition.

Position paper of the European Federation of IASP Chapters (EFIC) on the subject of pain management.

Among the complaints that bring patients to see their physician, pain in its various manifestations is the most frequent. In spite of this, pain is often not adequately addressed or managed. The aim of this position paper is to present the viewpoint and recommendations of EFIC on the subject of pain management.

Exploration of the evidence.

Faced with rapidly escalating costs, healthcare policy makers are increasingly turning to research evidence to serve as a basis for their population-based decisions on access and funding of new and existing therapies-health technology assessment. A two-stage approach is often used to arrive at a policy recommendation for a given treatment. First, following a systematic review of literature, the "level of evidence" for the treatment is assessed according to epidemiological principles.

Postherpetic neuralgia: the never-ending challenge.

Postherpetic neuralgia (PHN) is defined as pain that persists 1 to 3 months following the rash of herpes zoster (HZ). PHN affects about 50% of patients over 60 years of age and 15% of all HZ patients. Patients with PHN may experience two types of pain: a steady, aching, boring pain and a paroxysmal lancinating pain, usually exacerbated by contact with the involved skin.

New approach for spinal cord stimulation trial.

Spinal cord stimulation trial phase has remained unchanged for years. The common practice to connect a lead to an external transmitter is not optimal. The operational mode of transmitter is different from implanted system and external bulky device interferes with patient's daily routine.

Postherpetic neuralgia: what do we know and where are we heading?

Postherpetic neuralgia (PHN) remains a difficult pain problem for patients and physicians alike. This review describes the epidemiology and pathophysiology of PHN and discusses proposed mechanisms of pain generation and the various treatments currently available. Evidence is scant for the value of surgical and procedural interventions in general, although there are numerous small studies supporting the use of specific interventions such as nerve blocks, neurosurgical procedures and neuroaugmentation.

Causes of pain in degenerative bone and joint disease: a lesson from vertebroplasty.

Pain in degenerative bone and joint disease is usually attributed to sensitized nociceptors in inflamed periarticular soft tissues. Here we draw attention to the potential contribution of intrinsic bone innervation. The structure and innervation of articular bone ends is analogous to that of teeth.

Late antinociception and lower untoward effects of concomitant intrathecal morphine and intravenous buprenorphine in humans.

Study Objective: To evaluate the perioperative antinociceptive effect of intrathecal morphine (a pure mu agonist), intravenous (IV) buprenorphine (a partial mu agonist) or their combination.

Design: Randomized, double-blind, placebo-controlled study.

Settings: Anesthesiology department of a university-affiliated public hospital.
