Emotional Intelligence and Good Medical Practice: Is There a Relationship?

Emotional intelligence (EI) is defined as the ability to perceive and manage the emotions of oneself and others. Despite being one of the most highly used psychological terms in popular nomenclature, its understanding in the context of clinicians remains poor. There is a dearth of literature on this topic, and this submission examines the relationship between a clinicians' EI and the key domains of "Good Medical Practice" guidelines from the General Medical Council, United Kingdom.

Inflammatory arthritis and the elbow surgeon.

The treatment of inflammatory arthritis with disease modifying drugs and biological agents had reduced the number of patients needing surgical treatment. Surgical treatment of patients with inflammatory arthritis is challenging not only due to the factors such as bone stock and status of soft tissue but also due to the comorbidities associated with inflammatory arthritis. Multidisciplinary approach to these patients is recommended to deal with the complex poly-articular involvement and systemic physiological impairment especially when planning surgery.

Angiogram negative subarachnoid haemorrhage: outcomes and the role of repeat angiography.

Background: Angiogram negative sub-arachnoid haemorrhage (SAH) is generally considered to have a more benign course than SAH of known cause. There is also variability from centre to centre as to what proportion of angiogram negative SAH patients undergo repeat Digital Subtraction Angiography (DSA). We performed a retrospective study looking at the last four years' of SAH patients at our institution in order to ascertain the clinical course, the nature and results of repeat imaging.

Botulinum neurotoxin type A causes shifts in myosin heavy chain composition in muscle.

Botulinum neurotoxin type A has gained widespread use for treatment of a host of neuromuscular conditions. However, the potential effect of this toxin has on the histological and biochemical properties of skeletal muscle remains largely unexplored. The purpose of this study was to characterize the myosin heavy chain (MHC) distribution of adult rat skeletal muscle treated with botulinum neurotoxin type.

Does reducing spasticity translate into functional benefit? An exploratory meta-analysis.

Background: Spasticity and loss of function in an affected arm are common after stroke. Although botulinum toxin is used to reduce spasticity, its functional benefits are less easily demonstrated. This paper reports an exploratory meta-analysis to investigate the relationship between reduced arm spasticity and improved arm function.

Botulinum toxin (Dysport) treatment of hip adductor spasticity in multiple sclerosis: a prospective, randomised, double blind, placebo controlled, dose ranging study.

Objective: To define a safe and effective dose of Dysport for treating hip adductor spasticity.

Methods: Patients with definite or probable multiple sclerosis, and disabling spasticity affecting the hip adductor muscles of both legs, were randomised to one of four treatment groups. Dysport (500, 1000, or 1500 Units), or placebo was administered by intramuscular injection to these muscles.

A double blind, randomised, parallel group study to investigate the dose equivalence of Dysport and Botox in the treatment of cervical dystonia.

[High-risk surgical patients. Who are they and how should they be treated?].

This review addresses the currently available information that describes the identification of high risk patients undergoing surgery and how they may be treated to improve their outcome. It is clear from this data that high risk patients have a mortality rate of around 30% and that the major cause of death is due to multiple organ failure (MOF) which occurs days or in some cases weeks after the operation. The hypothesis for the onset of MOF is presented and it relates to the breakdown in gut patency which can allow the translocation of initiating inflammatory mediators which sets the MOF cascade in action.

Clinical studies with granisetron, a new 5-HT3 receptor antagonist for the treatment of cancer chemotherapy-induced emesis. The Granisetron Study Group.

Granisetron (BRL 43694A) is a novel, selective 5-hydroxytryptamine-3 (5-HT3) receptor antagonist developed for the prophylaxis and treatment of cytostatic drug-induced emesis. After a brief review of the preclinical evaluation of granisetron the clinical findings with this novel compound are summarised. From the data of large randomised trials one can conclude that granisetron is an active antiemetic, both as a prophylactic and an intervention agent, to an extent which is superior or at least equal to the best available antiemetic combination regimens, having a major efficacy ranging from 74 to 92%.

Can genetic polymorphism of alpha-2-macroglobulin be detected by immunoelectrophoresis? A study using sera, plasma and joint fluids from patients with rheumatoid arthritis and controls.

The technique of immunoelectrophoresis (IEP) was used to examine polymorphism of the endopeptidase inhibitor alpha-2-macroglobulin (alpha 2M) by measuring its electrophoretic mobility.

The visualization and characterization of two immunological forms of alpha 2 macroglobulin by immunoelectrophoretic methods.

Two peaks of alpha 2 macroglobulin (alpha 2M) were demonstrated in serum or plasma treated with trypsin using crossed immunoelectro-phoresis (CIEP). Both peaks moved the same distance in the first dimension and separated only when electrophoresed into antibody containing gel. The double peak phenomenon was shown not to be an artefact of the antiserum used and that the sample had to be fresh for both peaks to be visualised.
