Minor surgery in general practice in Ireland- a report of workload and safety.

BACKGROUND: The provision of minor surgical services is an established part of the task profile of general practitioners (GPs) in many countries in Europe and elsewhere. This study aimed to collect data on the clinical process and outcomes for specified minor surgical procedures undertaken in Irish general practice by GPs experienced in minor surgery in order to document the scope and safety of minor surgery being undertaken. METHODS: Over a six-month period, 24 GPs in 20 practices recorded data on a pre-determined list of procedures undertaken in adults (aged 18 and older); procedures for ingrown toenails were also recorded for those aged 12-18 years. Clinical data were rendered fully anonymous by the participating GPs, entered onto the Excel database template and returned to the project team monthly. RESULTS: On average, each practice undertook 212 procedures in a six-month period. The four most frequent procedures include two relatively non-invasive procedures (cryosurgical ablation of skin lesions and aspiration and/or injection of joints) and two more invasive procedures (full thickness excision of skin lesion and shave, punch or incisional biopsy). Overall, 83.8% of relevant specimens were submitted for histology. Combining benign and malignant cases, there was an overall 87% clinical and histological concordance; 85% of malignancies were suspected clinically. A complication was recorded in 0.9% after 1 month. CONCLUSIONS: Irish GPs with experience in minor surgery can provide a range of surgical services in the community safely.

Key writings in GP specialist training in Ireland.

Key writings are those texts which represent a timeless contribution to the academic basis of general practice. We surveyed the 14 GP Specialist Training Programmes in Ireland and undertook focus group interviews with teachers and trainees in order to understand the extent to which such texts are currently used and whether they are valued in teaching. Our results indicate that traditional reading lists are not common in Irish GP training, that there are many barriers to trainees engaging with such literature but that both teachers and trainees see merit in providing access to a body of key writings. We suggest how this might be undertaken.

COPD Patients Have Short Lung Magnetic Resonance T1 Relaxation Time.

Magnetic resonance imaging (MRI) may provide attractive biomarkers for assessment of pulmonary disease in clinical trials as it is free from ionizing radiation, minimally invasive and allows regional information. The aim of this study was to characterize lung MRI T1 relaxation time as a biomarker of chronic obstructive pulmonary disease (COPD); and specifically its relationship to smoking history, computed tomography (CT), and pulmonary function test (PFT) measurements in comparison to healthy age-matched controls. Lung T1 and inter-quartile range (IQR) of T1 maps from 24 COPD subjects and 12 healthy age-matched non-smokers were retrospectively analyzed from an institutional review board approved study. The subjects underwent PFTs and two separate MR imaging sessions at 1.5 tesla to test T1 repeatability. CT scans were performed on the COPD subjects. T1 repeatability (intraclass correlation coefficient) was 0.72 for repeated scans acquired on two visits. The lung T1 was significantly shorter (p < 0.0001) and T1 IQR was significantly larger (p = 0.0002) for the COPD subjects compared to healthy controls. Lung T1 significantly (p = 0.001) correlated with lung density assessed with CT. Strong significant correlations (p < 0.0001) between lung T1 and all PFT measurements were observed. Cigarette exposure did not correlate with lung T1 in COPD subjects. In conclusion, lung MRI T1 mapping shows potential as a repeatable, radiation free, non-invasive imaging technique in the evaluation of COPD.

Feasibility assessment of using oxygen-enhanced magnetic resonance imaging for evaluating the effect of pharmacological treatment in COPD.

OBJECTIVES: Oxygen-enhanced MRI (OE-MRI) biomarkers have potential value in assessment of COPD, but need further evaluation before treatment-induced changes can be interpreted. The objective was to evaluate how OE-MRI parameters of regional ventilation and oxygen uptake respond to standard pharmacological interventions in COPD, and how the response compares to that of gold standard pulmonary function tests. MATERIALS AND METHODS: COPD patients (n=40), mean FEV1 58% predicted normal, received single-dose inhaled formoterol 9µg, or placebo, followed by 8 weeks treatment bid with a combination of budesonide and formoterol Turbuhaler(®) 320/9µg or formoterol Turbuhaler(®). OE-MRI biomarkers were obtained, as well as X-ray computed tomography (CT) biomarkers and pulmonary function tests, in a two-center study. An ANCOVA statistical model was used to assess effect size of intervention measurable in OE-MRI parameters of lung function. RESULTS: OE-MRI data were successfully acquired at both study sites. 8-week treatment with budesonide/formoterol significantly decreased lung wash-out time by 31% (p<0.01), decreased the change in lung oxygen level upon breathing pure oxygen by 13% (p<0.05) and increased oxygen extraction from the lung by 58% (p<0.01). Single-dose formoterol increased both lung wash-out time (+47%, p<0.05) and lung oxygenation time (+47%, p<0.05). FEV1 was improved by single-dose formoterol (+12%, p<0.001) and 8 weeks of budesonide/formoterol (+ 18%, p<0.001), consistent with published studies. CONCLUSIONS: In COPD, OE-MRI parameters showed response to both single-dose bronchodilatory effects of a ß2-agonist, formoterol, and 8-week treatment with an inhaled corticosteroid, budesonide, and the measurements are feasible in a small-scale multi-center trial setting.
