    Notes: Abstract. Calcium phosphate coatings were deposited on Ti-6Al-4V by laser ablation with a 355 nm Nd:YAG laser at different substrate temperatures. Two series of coatings were deposited at water vapour pressures of 10 and 45 Pa by varying the substrate temperature from 20 to 600 °C. Characterisation of their structure and adhesion has been carried out in order to study the effect of the deposition temperature and the water vapour pressure on the coating properties. It has been found that a high temperature favours the synthesis of crystalline phases. Ca rich phases are synthesised at 10 Pa while hydroxyapatite is obtained at 45 Pa with some alfa tricalcium phosphate. Scratch test measurements have shown, that the coating-substrate adhesion for coatings deposited at 45 Pa is remarkably increased at substrate temperatures higher than 400 °C, but the highest adhesion has been found for amorphous coatings obtained at 10 Pa and 200 °C.

    Notes: Abstract Oesophageal dilatation is the most widely used treatment option for the management of oesophageal strictures. Complications include bleeding, a slight increase in body temperature, thoracic or abdominal pain, oesophageal perforation, brain abscess and bacteraemia. We performed a prospective study to evaluate the frequency of postdilatation bacteraemia in nine patients subjected to a total of 50 dilatations. Bacteraemia was detected in 36 cases (72%), In all but three cases, however, it was transient and not associated with fever or other clinical complications. The organisms most commonly responsible (64%) were alpha-haemolytic streptococci (Streptococcus viridans), probably originating as contaminants from the oropharynx and oesophagus and introduced into the bloodstream during dilatation. Despite the relatively low incidence of bacteraemia-related postdilatation complications, the potential severity of such complications argues for the use of antibiotic prophylaxis as a routine measure prior to oesophageal dilatation. Conclusion Oesophageal dilatation is associated with a high incidence of bacteraemia. The organisms most commonly responsible were alpha-haemolytic streptococci. We recomend the use of antibiotic prophylaxis as a routine measure prior to oesophageal dilatation.

    Notes: Abstract We reviewed the case histories of 743 children seen at our hospital from 1981 to 1990 for suspected ingestion of caustic substances. Mean patient age was 27 months; 85% of patients were less than 3 years old. The male-to-female ratio was about 2:1. About 53% of patients were from urban environments. All ingestions appear to have been accidental. Of the 743 children, 20% presented oesophageal burns (11.8% first-degree, 3.1% second-degree and 2.7% third-degree). Alkaline products were ingested about 11 times more frequently than acid products. The substance ingested was bleach in 73% of cases. The most dangerous substances were dishwasher liquids/powders (59% of ingestions led to oesophageal burn), caustic soda (55%) and drain cleaners (55%). The caustic product was not in its original container in 75% of cases. Most accidents (58%) took place in the home. We did not detect any reliable predictive relationship between the presence of symptoms and signs and of oesophageal burns. Of the 743 patients, 5% developed oesophageal stricture and 3% required oesophageal dilatation. Conclusion The incidence of accidents caused by the ingestion of caustic substances can only be reduced by broad-based preventive strategies, including enforcement of safe manufacturing practices and public education programmes. Most importantly, the containers for caustic household products should be cheap, small and childproof.

    Notes: Summary From a clinical standpoint recovery of spinal nerve roots is less likely than that of peripheral nerves, despite their identical structures. This may be due to several factors including the length of gap to be bridged, changes in the proximal stump or neuroma, and chromatolysis. In this paper we discuss the roles of some of these factors in relation to the neuronal depopulation in the spinal cord anterior horn area following section of the anterior root. The lack of growth or the successful growth of the axon through the gap in the root influences the degree of depopulation in the anterior horn area.

    Notes: Particulate reinforced titanium composites were produced by PM route. Differentvolumetric percentages of TiN reinforcements were used, 5,10,15 vol%. Samples were uniaxiallypressed and vacuum sintered at different temperatures between 1200-1300ºC. Density, porosity,shrinkage, mechanical properties and microstructure were studied. Elastic properties and strengthresistance were analysed by flexural strength and tension tests, and after the test, fractured sampleswere analysed as well to obtain the correlation between the fracture, interparticular orintraparticular, and the level of reinforcement addition. Hardness and microhardness test were doneto obtain a better understanding of its mechanical properties. In order to study wear resistance pinon-disc tests were conducted. In addition, the influence of temperature, the reactivity betweenmatrix and reinforcement on microstructural development were observed by optical and electronmicroscopy

    Notes: Objectives:  To determine if motivation to change in anorexia nervosa during treatment is a predictor of hospitalisation in adolescent patients.Method:  The Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ), the Eating Disorders Inventory-2 (EDI-2) and the Beck Depression Inventory (BDI) were administered to a group of 70 anorexia nervosa patients (mean age 15.6 years). They were all receiving treatment at a specialised Eating Disorder Unit and were at different points in the treatment programme. Admission during 6–9 month follow-up was recorded in 63 of these patients who had been admitted to the Unit. The other 7 patients were contacted by phone to determine if they had been hospitalised in another unit during the follow-up period.Results:  Patients who needed hospital admission during follow-up had higher mean scores at first evaluation on some of the EDI-2 scales and on the BDI, lower ANSOCQ scores and were more likely to have been outpatients at first evaluation. In the logistic regression analysis a low ANSOCQ score and being an outpatient at first evaluation were shown to be independent predictors of hospitalisation during follow-up.Conclusions:  Low motivation to change, depressive symptomatology and some EDI-2 scales are related to the necessity of hospital admission in adolescent patients with anorexia nervosa.
