Gout and hyperlipidaemia. Effect of overweight on the levels of circulating lipids

A study of the serum lipids in 90 patients with gout and 90 controls matched for age and weight index demonstrated that in gout there was a significant elevation of the mean serum levels of cholesterol (282 +/- 55 mg/100 ml), triglycerides (183 +/- 161 mg/100 ml) and phospholipids (270 +/- 61 mg/100 ml) compared with the controls whose mean values were respectively 243 +/- 41 mg, 95 +/- 53 mg and 245 +/- 36 mg. Hyperlipidaemia of mixed type was the most common lipid defect in the patients with gout; there was no difference in the frequency of pure hypercholesterolaemia (without hypertriglyceridaemia) between gout and the controls. The frequency of anomalies of blood lipid levels in gout does not result from (or not solely from) obesity since patients with gout and controls were matched for their weight and height. There was a correlation between the serum lipid levels and obesity in the controls but this was not demonstrable in the patients with gout.     

Relationship between smoking status and serum lipids in a hyperlipidemic population and analysis of possible confounding factors.

The aim of our study was to estimate the potential relationship between smoking behavior and other coronary heart disease risk factors in 250 hyperlipidemic patients. We present data obtained through self-reporting of the number of cigarettes smoked per day, measurements of three tobacco markers, and data on dietary habits and lipid variables. We measured cotinine (by HPLC) and thiocyanate and used a recent colorimetric assay for the indirect evaluation of the nicotine metabolites in a single urine specimen. Mean values of nicotine metabolites, expressed as cotinine equivalents, were 6.7, 39.9, and 79.4 mumol/L, respectively, for nonsmokers, light smokers (7.7 cigarettes per day), and heavy smokers (25.8 cigarettes per day). We found that light smokers have higher concentrations of cotinine and nicotine metabolites in proportion to the number of cigarettes smoked per day than do heavy smokers. Thus, the simple colorimetric assay can accurately evaluate smoking status. Hyperlipidemia and smoking are linked by an intricate network of multiple relations. The concentration of high-density lipoprotein (HDL) cholesterol is lower in heavy smokers, and the concentrations of triglycerides and cholesterol are higher. The 0.11 mmol/L difference in HDL cholesterol between light and heavy smokers is close to the results of previous papers; however, when gender, dietary habits (including alcohol intake), and data on body mass index are included in a multiple regression analysis, there is no longer an association between HDL cholesterol concentrations and smoking status. Therefore, these different dietary habits may be confounding factors that partly explain the pattern of lipid variables.     

European online postgraduate educational programme in neonatology—the way forward?

The provision of specialist postgraduate training is increasingly challenging for the acute medical specialties. There are often small numbers of trainees and tutors in any one centre, and service commitments may limit attendance at educational activities. Online learning can provide high-quality education to trainees from large geographical areas. We report the outcomes of an experimental educational project which provided an online postgraduate programme in neonatology. Ninety trainees from 14 countries, primarily European, participated. Six educational modules in neonatal topics were delivered over a 1-year period, within a “Virtual Learning Environment”. Trainees were divided into multi-national groups; two online tutors supported each group. Analysis of online activity demonstrated that active participation was high initially (100%) but gradually declined to 46% in the final module; tutor participation followed a similar pattern. Eighty-six trainees were contactable at the end of the programme, and 67 (78%) completed an evaluation questionnaire. Of these, 92% reported that participation had “added value” to their training, attributable to the high-quality curriculum, the educational resources, collaborative networking and the sharing of best practice. Eleven (79%) tutors completed the questionnaire, with all reporting that participation was of educational value. The main limiting factor for trainees and tutors was insufficient time. This project confirms that multi-national online education in neonatology is feasible and transferable, but for this approach to be viable formal accreditation and protected time for both trainees and tutors are required.     

Gluthathion synthetase deficit in a newborn infant.]

CASE REPORT: We report an observation of a triplet newborn presenting with haemolysis, metabolic acidosis with no lactic acidosis revealing a glutathione synthetase deficiency. These biological signs were associated with multiple malformations (IUGR, toes hypoplasia and cerebral ventricular anomalies), not described in this disease. CONCLUSION: This rare diagnosis can be confirmed by elevation of urinary 5-oxoproline. Prognosis is linked to diagnosis and treatment precocity. We have no argument to think that the malformations we found are related to a glutathione synthetase deficiency. However, as the neurological evolution is often unfavourable, neuroradiological explorations could give information about the location and severity of potential cerebral lesions.     

Multicentric study on neonatal medical pain management in the Nord-Pas-de-Calais]

The aim of this study was to describe pain management for newborn infants in neonatal intensive care units and neonatal units in the Nord-Pas-de-Calais. PATIENTS AND METHODS: A questionnaire was distributed to the 52 physicians practising in the six neonatal intensive care units and six neonatal units. The questions were in reference to pain assessment, treatment and prevention. RESULTS: Forty questionnaires were completed (77%). Eleven units proclaimed an interest in neonatal pain management. The tool for assessing pain was the EDIN scale (Echelle Douleur Inconfort Nouveau-né, neonatal pain and discomfort scale). Analgesic treatment was administered in 100% of cases for the insertion of chest tube, in 92% of cases for the insertion of percutaneous central catheter in a ventilated newborn infant and in 91% of cases for necrotizing enterocolitis requiring a mechanical ventilation. Prescribed analgesic drugs were propacetamol, nalbuphin or fentanyl; a sedation by midazolam or diazepam was occasionally associated. Emla cream was used before lumbar puncture in 80% of cases in the neonatal intensive care units and in 92% of cases in the neonatal units. Three neonatal intensive care units and four neonatal units administered a sucrose solution for blood samples. CONCLUSION: At the time of study, the interest in the pain of the physicians working in neonatal intensive care units and neonatal units was inadequate to guarantee an optimum management of pain in newborn infants. Physicians' approach remained heterogeneous.
