Secondary prevention and referral of elderly patients to a cardiovascular lipid service

The burden of cardiovascular disease in the elderly has increased interest in lipid profiles which retain associations with outcome except at extreme age and for which management has benefits at least in secondary prevention. The source, clinical and laboratory background of 90 male and 120 female consecutive referrals age >70 years to a specialist cardiovascular lipid service have been analysed. Main sources were vascular surgery 47%, cardiology 9% and general practice 41% with 6% referred through routine health checks. Presenting lipids (mM: mean+/-S.D.) were: males: cholesterol 6.9+/-1.7, triglycerides 2.3+/-1.5, HDL 1.2+/-0.3; females: cholesterol 7.8+/-1.4, triglycerides 2.1+/-1.3, HDL 1.5+/-0.5, consistent with greater awareness of lipid-related problems in males but significant vascular disease in females. Secondary lipemia was defined in 131/210, 62.3% of patients (83 recognised before clinic presentation, 48 found at follow-up, mainly diabetes). Significant vascular disease was identified in 166/210 patients, significant other risk factors in another 35 patients. Levels of lipoprotein(a) were widely distributed for all groups, but elevated against population profiles for all groups with vascular disease. Referrals were monitored and not routinely accepted: reassuringly most then accepted were justified through atheroma-related disease and opportunities for secondary prevention, with little additional burden through untargeted routine health checks. Recognition of and management of secondary lipemia and obesity were however incomplete.     

Relationship between the chest radiograph, regional lung function studies, exercise tolerance, and clinical condition in cystic fibrosis

This study evaluated the accuracy of the interpretation of the chest film in delineating localised abnormalities of ventilation and perfusion, as well as the overall severity of airways obstruction, exercise tolerance, and clinical condition in children with cystic fibrosis. Radiographic findings in various regions of the chest film were compared with the functional values obtained with regional lung function tests which evaluated the arrival and disappearance of boluses of radioactive nitrogen given by inhalation and infusion. While the more severely affected areas on the chest radiograph were found to correlate with similar regions on the lung function tests, as did overall scores, errors occurred in some cases if the x-ray film alone was used as a judge of regional physiological derangement. In addition the degree of airways obstruction, the exercise tolerance on a cycle ergometer, and clinical grading, each correlated significantly with the radiographic score. We conclude that the chest radiograph is a good indicator of the overall severity of the lung disease and that it correlates well with exercise tolerance and clinical condition in cystic fibrosis.     

Duties of a doctor: UK doctors and Good Medical Practice

OBJECTIVE: To assess the responses of UK doctors to the General Medical Council's (GMC) Good Medical Practice and the Duties of a Doctor, and to the GMC's performance procedures for which they provide the professional underpinning. DESIGN: Questionnaire study of a representative sample of UK doctors. SUBJECTS: 794 UK doctors, stratified by year of qualification, sex, place of qualification (UK v non-UK), and type of practice (hospital v general practice) of whom 591/759 (78%) replied to the questionnaire (35 undelivered). MAIN OUTCOME MEASURES: A specially written questionnaire asking about awareness of Good Medical Practice, agreement with Duties of a Doctor, amount heard about the performance procedures, changes in own practice, awareness of cases perhaps requiring performance procedures, and attitudes to the performance procedures. Background measures of stress (General Health Questionnaire, GHQ-12), burnout, responses to uncertainty, and social desirability. RESULTS: Most doctors were aware of Good Medical Practice, had heard the performance procedures being discussed or had received information about them, and agreed with the stated duties of a doctor, although some items to do with doctor-patient communication and attitudes were more controversial. Nearly half of the doctors had made or were contemplating some change in their practice because of the performance procedures; a third of doctors had come across a case in the previous two years in their own professional practice that they thought might merit the performance procedures. Attitudes towards the performance procedures were variable. On the positive side, 60% or more of doctors saw them as reassuring the general public, making it necessary for doctors to report deficient performance in their colleagues, did not think they would impair morale, were not principally window dressing, and were not only appropriate for problems of technical competence. On the negative side, 60% or more of doctors thought the performance procedures were not well understood by most doctors, were a reason for more defensive practice, and could not be used for problems of attitude. Few differences were found among older and younger doctors, hospital doctors, or general practitioners, or UK and non-UK graduates, although some differences were present. CONCLUSIONS: Most doctors working in the UK are aware of Good Medical Practice and the performance procedures, and are in broad sympathy with Duties of a Doctor. Many attitudes expressed by doctors are not positive, however, and provide areas where the GMC in particular may wish to encourage further discussion and awareness. The present results provide a good baseline for assessing changes as the performance procedures become active and cases come before the GMC over the next few years.     

Spondylometaphyseal dysplasia, corner fracture type: a heritable condition associated with coxa vara

The authors present the radiographic features of a previously incompletely delineated bone dysplasia, which they call spondylometaphyseal dysplasia, corner fracture type. This is a dominant heritable condition associated with short stature and developmental coxa vara. The progressive hip deformity usually causes significant disability requiring surgical correction. Developmental coxa vara, simulated corner fractures of long tubular bones, and vertebral body abnormalities result in a diagnostic constellation. Knowledge of these distinctive radiologic features allows accurate diagnosis, which in turn should lead to appropriate genetic counseling and possibly to earlier, more efficacious surgical treatment of the coxa vara.     

Ulnar nerve injuries of the hand producing intrinsic muscle denervation on magnetic resonance imaging

Muscle and nerve injuries in the hand may be difficult to detect and diagnose clinically. Two cases are reported in which magnetic resonance imaging showed ulnar nerve injury and intrinsic hand muscle denervation. The clinical, anatomical and radiological features of injury to the deep motor branch of the ulnar nerve and associated muscle denervation are discussed and illustrated.     

Indium-111 labeled platelet deposition following transfemoral angiography

The incidence of thromboembolitic events in patients undergoing transfemoral angiography was examined using indium-111 labeled platelets. Twenty-seven patients received approximately 300 muCi of autologous labeled platelets at least 3 hours before angiography and were scanned with a gamma camera immediately before and after angiography. All patients were free of clinically obvious complications in the 1-2 day period after angiography. Our results showed evidence of platelet deposition at 21 sites other than the puncture site in 12 (44%) patients. Most platelet deposition (54%) occurred along the region between the puncture site and the aortic bifurcation; 24% occurred at sites not traversed by the catheter. At the puncture site itself, there was substantial platelet uptake in 44% of patients. This study indicates the need for further work in determining the most suitable catheter material and in assessing the efficacy of other measures such as anticoagulant or antiplatelet therapy.     

Thoracic outlet syndrome: evaluation with CT

Diagnosis of the thoracic outlet syndrome is often difficult, particularly in patients without osseous abnormalities on plain radiographs. The radiographic and computed tomographic (CT) findings were reviewed from 27 patients with thoracic outlet syndrome and 21 normal subjects. The plain radiographs and CT scans were assessed by two independent observers without awareness of the clinical history. Fifteen patients with thoracic outlet syndrome had osseous abnormalities (anomalous cervical ribs; abnormally long, drooping C-7 transverse processes) identifiable on plain radiographs. CT did not provide further diagnostic information in the patients with abnormal radiographs. Eight of 12 patients (66%) with normal plain radiographs had abnormal findings on CT scans, consisting of impingement of the C-7 transverse process on the scalene triangle or anteromedial aspect of the middle scalene muscle. Only two of 21 control patients (9.5%) displayed this CT abnormality (P less than .01). CT may be useful in patients with symptoms suggestive of thoracic outlet syndrome and no osseous abnormalities on plain radiographs.     

Tongue and oropharynx: findings on MR imaging

Ten healthy subjects and 44 patients with diseases of the tongue or oropharynx were studied with magnetic resonance (MR) imaging. Axial, coronal, and sagittal images with a thickness of 4 mm were obtained with a pixel size of 0.75 X 0.75 mm on a 256 matrix. Nineteen of the patients underwent computed tomography (CT). Nine of those patients later had surgery, and the specimens were obtained for organ sectioning. These three studies as well as clinical history and physical examination findings were correlated. MR imaging was equal to or better than CT in those patients having both examinations. However, neither CT nor MR allowed recognition of histologic features or detection of microscopic spread of disease. Direct coronal and sagittal imaging planes on MR imaging allowed visualization of intrinsic tongue musculature, not possible with CT; this was important in recognizing subtle tumor extension. For these reasons, MR is the imaging method of choice for studying diseases of the tongue and oropharynx.     

Continence assessment in primary care: what is the next step?

There are many assessment 'forms' available for the collection of information in relation to bladder dysfunction. In many cases such forms have not been fully validated and should only be considered on a face validity basis. Validated symptom scores are available but these are generally used within specific areas of urology, e.g. lower urinary tract symptom scores for prostate screening. This article explores the need for an improved validated assessment and symptom scoring tool for nurses within primary care, to enable nurses to establish a preliminary diagnosis in adult patients presenting with bladder symptoms.
