ReviewPulmonary hypertension: advances in pathogenesis and treatment.
Pulmonary hypertension is an orphan disease that until recently has received limited attention within the wider medical community. This has changed distinctly in the last 10 years with the advent of new classes of therapy and a renewed interest in mechanisms of pathogenesis. ⋯ We will discuss interesting new concepts in pathogenesis, including the importance of genetic forms of the disease and in particular the transforming growth factor receptor superfamily and the evolving evidence of the contribution of dysregulated immunity. Areas of research may yield therapeutic benefits in the not-too-distant future, including anti-proliferative therapies and stem cell therapy.

The number of people with dementia will rise dramatically over the next 20 years. Currently, one in three people over the age of 65 will die with dementia. A PubMed search using MeSH headings for 'dementia' AND 'palliative care' and for specific areas, i.e. enteral feeding. ⋯ People with dementia have poor access to good quality end-of-life care. Interventions such as antibiotics, fever management policies and enteral tube feeding remain in use despite little evidence that they improve quality of life or other outcomes. Research is required on the effectiveness of 'holistic' palliative care, outcome measures and the impact on carers and families.

Multiple sclerosis (MS) is the commonest disabling neurological condition to afflict young adults and therefore has a high social burden. Over several decades, there has been a considerable progress in the understanding of the disease pathogenesis as well as in the clinical management of MS patients. The emphasis in managing MS patients has shifted to multidisciplinary teams working in specialist groups. ⋯ This is an attractive concept that is not widely accepted. The observation that MS progresses despite immunosuppressive therapy suggests that MS may be a neurodegenerative disease with overlapping immune activation possibly in response to the release of central nervous system auto-antigens. The development of neuroprotective therapies for MS is required to prevent the devastating effects of long-term disability as a result of progressive disease.

Review Meta AnalysisExtracorporeal cardiac mechanical stimulation: precordial thump and precordial percussion.
External cardiac mechanical stimulation is one of the fastest resuscitative manoeuvres possible in the emergency setting. Precordial thump (PT), initially reported for treatment of atrio-ventricular block, has been subsequently described to cardiovert also ventricular tachycardia (VT) and fibrillation (VF). PT efficacy, mechanics and mechanisms remain poorly characterized. ⋯ The 2005 ALS guidelines recommend PT delivery only by healthcare professionals trained in the technique. The use of training aids should therefore be explored, regardless of whether they are based on stand-alone devices or integrated within resuscitation mannequins.

During the past decades several rating scales have been developed to assess the functional status of patients with low back pain. ⋯ Further studies are required to evaluate the reliability, validity and sensitivity of the low back pain scoring systems used in the common clinical practice.
