Objective: The study aimed to characterise the factors related to the X-ray dose delivered to the patient's skin during interventional cardiology procedures. Methods: We studied 177 coronary angiographies (CAs) and/or percutaneous transluminal coronary angioplasties (PTCAs) carried out in a French clinic on the same radiography table. The clinical and therapeutic characteristics, and the technical parameters of the procedures, were collected. The dose area product (DAP) and the maximum skin dose (MSD) were measured by an ionisation chamber (Diamentor; Philips, Amsterdam, The Netherlands) and radiosensitive film (Gafchromic; International Specialty Products Advanced Materials Group, Wayne, NJ). Multivariate analyses were used to assess the effects of the factors of interest on dose. Results: The mean MSD and DAP were respectively 389mGy and 65 Gy cm -2 for CAs, and 916mGy and 69 Gycm -2 for PTCAs. For 8% of the procedures, the MSD exceeded 2 Gy. Although a linear relationship between the MSD and the DAP was observed for CAs (r50.93), a simple extrapolation of such a model to PTCAs would lead to an inadequate assessment of the risk, especially for the highest dose values. For PTCAs, the body mass index, the therapeutic complexity, the fluoroscopy time and the number of cine frames were independent explanatory factors of the MSD, whoever the practitioner was. Moreover, the effect of technical factors such as collimation, cinematography settings and X-ray tube orientations on the DAP was shown. Conclusion: Optimising the technical options for interventional procedures and training staff on radiation protection might notably reduce the dose and ultimately avoid patient skin lesions. © 2012 The British Institute of Radiology.

Over the past few years, we have observed increasing consumption of inappropriate plant milks as an alternative to infant milk formula. Some families believe that foods labeled as natural are the most healthy and an appropriate nutritional choice. However, their composition does not respect European recommendations. They are always hypocaloric and protein, vitamin, and mineral concentrations are inadequate. The aim of this study was to report severe nutritional complications after inappropriate plant milk consumption. Between 2008 and 2011, we studied severe nutritional deficiencies caused by consumption of plant milks bought in health food stores or online shops. Infants were identified in our centers and examined through medical history, physical examination, and laboratory testing. Nine cases of infants aged from 4 to 14. months were observed. In all cases, these milks were used as an alternative to milk formulas for supposed cow's milk allergy. At diagnosis, four patients were aged 6. months or less. They had received plant milk exclusively for 1-3. months. The beverages consumed were rice, soya, almond and sweet chestnut milks. In three cases, infants presented severe protein-calorie malnutrition with substantial hypoalbuminemia (<. 20. g/L) and diffuse edema. In the other cases, the nutritional disorders were revealed by a refractory status epilepticus related to severe hypocalcemia (one case), growth arrest of both height and weight secondary to insufficient caloric intake (five cases), and severe cutaneous involvement (one case). Five children had severe iron deficiency anemia (<. 70. g/L), three children had a very low 25-hydroxy vitamin D level (nutritional rickets), and two had severe hyponatremia (<. 130. mmoL/L). Milk alternative beverages expose infants to severe nutritional deficiencies. Serious complications can occur. Early, exclusive, and extended use is riskier. These diseases are preventable, and parental education should be provided. Statutory measures forbidding their use in young infants should be organized to slow down the progress of this social trend. © 2014 Elsevier Masson SAS. Source
