Extracorporeal membrane oxygenation support in acute circulatory failure: A plea for regulation and better organization.

Emergent implantation of temporary mechanical circulatory support using venoarterial ECMO (ECLS for extracorporeal Life Support) is increasingly adopted in various indications of acute circulatory failure refractory to optimal medical treatment. To implant such devices, but also to provide appropriate daily management, expertise and adapted technical platform are required. Organization, coordination and regulation of such program are not clearly established in our country. We propose a dedicated territorial organization to improve and facilitate management of these specific and most severe patients.

Multimodality Imaging for Best Dealing With Patients in Atrial Arrhythmias.

The management of atrial fibrillation (AF) is not only a clinical challenge but also an imaging challenge. The role of different imaging modalities to estimate the thromboembolic risk in AF is a key clinical question. The present review summarizes the advances of myocardial imaging in the stratification of thromboembolic risk, diagnosis, and management of left atrial thrombosis in patients with AF. These imaging techniques are also important for understanding arrhythmias and their consequences. It is becoming fundamental for guiding therapy. Still, large studies are required, but be sure that left atrial imaging will become more and more clinically fundamental.

Comparison of traditional and abbreviated salbutamol aerosol therapy using a new spacer mouth mask.

Abbreviated aerosol therapy has been suggested to increase compliance by delivering the same therapeutic dose, but more rapidly than traditional aerosol therapy. A new spacer mouth mask, which is recommended for use in abbreviated aerosol therapy, is now available in Italy. The aim of this study was to compare traditional and abbreviated salbutamol aerosol therapy in 30 asthmatic children using the new spacer mouth mask. Thirty asthmatic children (18 boys and 12 girls; aged 4-13 years) were evaluated during severe asthma attacks (forced expiratory volume at 1 second [FEV(1)] <60% of the predicted value) and randomly allocated to treatment with two different schedules of aerosol therapy. Aerosol therapy was administered to group A in the usual manner, with patients breathing in and out at tidal volume until the nebulizer bowl was empty. Group B received therapy with the new spacer mouth mask used in accordance with manufacturer's instructions, i.e., placing the mask tightly over the mouth and instructing the child to breathe in through the mouth and out through the nose a total of five times at tidal volume, keeping the mouth open. The amount of drug available to patients in group A was approximately 768 microg, whereas 176 microg was available to those in group B. The FEV(1) increased in all patients and there was no difference in the degree of improvement between the groups (p < 0.05). The results indicate equivalent bronchodilatation between abbreviated and traditional aerosol therapy but because abbreviated therapy takes less time, it may improve compliance.

Coseasonal sublingual immunotherapy reduces the development of asthma in children with allergic rhinoconjunctivitis.

BACKGROUND: We wondered whether short-term coseasonal sublingual immunotherapy (SLIT) can reduce the development of asthma in children with hay fever in an open randomized study. OBJECTIVE: We sought to determine whether SLIT is as effective as subcutaneous immunotherapy in reducing hay fever symptoms and the development of asthma in children with hay fever. METHODS: One hundred thirteen children aged 5 to 14 years (mean age, 7.7 years) with hay fever limited to grass pollen and no other clinically important allergies were randomized in an open study involving 6 Italian pediatric allergy centers to receive specific SLIT for 3 years or standard symptomatic therapy. All of the subjects had hay fever symptoms, but at the time of study entry, none reported seasonal asthma with more than 3 episodes per season. Symptomatic treatment was limited to cetirizine, loratadine, nasal budesonide, and salbutamol on demand. The hay fever and asthma symptoms were quantified clinically. RESULTS: The actively treated children used less medication in the second and third years of therapy, and their symptom scores tended to be lower. From the second year of immunotherapy, subjective evaluation of overall allergy symptoms was favorable in the actively treated children. Development of asthma after 3 years was 3.8 times more frequent (95% confidence limits, 1.5-10.0) in the control subjects. CONCLUSIONS: Three years of coseasonal SLIT improves seasonal allergic rhinitis symptoms and reduces the development of seasonal asthma in children with hay fever.

Soy protein formulas in children: no hormonal effects in long-term feeding.

Recently, the finding of high plasma concentration of phyto-oestrogens in soy protein formula (SPF) fed children has focused scientific attention on the phyto-oestrogens (isoflavones genistein, daidzein, and their glycosides) contained in SPFs. The aim of this study was to evaluate some hormonal and metabolic effects of long-term (more than 6 months) SPF feeding. We enrolled 48 children, mean age 37 months (range 7-96 months), 27 males and 21 females. All children underwent physical examination. Bone age, urinary markers of bone metabolism, serum levels of bone alkaline phosphatase, osteocalcin, 17beta-oestradiol, and intact parathyroid hormone were measured. Eighteen healthy children represented the control group. No abnormalities were observed in auxological parameters; none of the enrolled girls showed signs/symptoms of precocious puberty and none of the boys presented gynecomastia; bone age was within the normal range. The serum level of bone alkaline phosphatase, osteocalcin, 17beta-oestradiol, and intact parathyroid hormone, and the urinary levels of the markers of bone metabolism were all within normal values. We conclude that long-term feeding with SPFs in early life does not seem to produce oestrogen-like hormonal effects.

Soy formulas and nonbovine milk.

BACKGROUND: Cow's milk allergy is frequently observed during the first year of life when nutritional requirements are critical. In those cases where breast-feeding is not available, a safe and adequate substitute to cow's milk should be offered. OBJECTIVE: The primary aim of this review is to evaluate the clinical use of milk derived from vegetable proteins, such as soy, or from animals such as goat, mare, or donkey, or elemental diet in children with cow's milk allergy. METHODS: MEDLINE searches were conducted with key words such as soy, goat's milk, donkey's milk, mare's milk, and elemental diet. Additional articles were identified from references in books or articles. Original research papers and review articles from peer-reviewed journals were chosen. RESULTS: Soy formulas are nutritionally adequate and can be used in children with immunoglobulin E-mediated nongastrointestinal manifestations of cow's milk allergy. Goat's milk is as allergenic as cow's milk. Mare's milk and donkey's milk may be used in selected cases of cow's milk allergy after appropriate modification to make them suitable for human infants. Elemental diets are usually restricted to the most severe cases of cow's milk allergy (ie, sensitivity to extensively hydrolyzed protein formulas). CONCLUSIONS: Vegetable formulas obtained from soy and milk derived from other mammals, such as mare or donkey, homemade preparations, and elemental diet may represent valid alternatives for children with cow's milk allergy. Extensive clinical trials are needed on the safety profile of any alternative mammal-derived milk. The choice of alternative milk should take into account the clinical profile of the child allergic to cow's milk, particularly as concerns age, severity of symptoms, degree of sensitivity to cow's milk proteins, and any multiple food allergies.
