Exposures associated with making or playing with viscoelastic polymer toys known as Slime: a retrospective case series from French Poison Control Centres.

Context: Slime is a slow-flowing material with viscoelastic properties which is attractive to children. Its preparation is based on the crosslinking of polyvinyl alcohol, polyvinyl acetate or starch with boric acid.Objectives: The goal of this study was to describe the adverse effects of Slime.Materials and methods: This is a descriptive retrospective study of cases of exposure reported to French Poison Control Centres between January 2014 and May 2018. The following parameters were used: age and sex, date and circumstances of exposure, symptoms and severity.Results: Two hundred and eight (208) cases of exposure were recorded, 93 cases happened in 2017, and 88 cases in the first four and a half months of 2018. The average age was of 8 years old; 190 patients were younger than 15. Fifty-seven percent (57%) were female. Regarding routes of exposure, 168 were oral, 30 cutaneous, eight ocular, one inhalation and one ear exposure. Eighty-two (82) patients were symptomatic, including 81 cases of low severity and one of average severity (keratitis). All cases lead to recovery.Conclusion: No significant adverse health effects are expected to develop if only small amounts are swallowed; making Slime with home ingredients is a potential cause of boric acid exposure that must be supervised by adults.

Poisoning by non-edible squash: retrospective series of 353 patients from French Poison Control Centers.

CONTEXT: Among the numerous varieties of squash that exist, some are edible while other bitter-tasting ones are not fit for human consumption. Cases of confusion seem to be multiplying and are characterized by digestive problems (diarrhea, vomiting, and abdominal pain). METHODS: This is a descriptive retrospective study of cases of exposure reported to French Poison Control Centers between 1 January 2012 and 12 December 2016. RESULTS: 353 patients were included, with 71.7% belonging to collective cases of poisoning. The male to female sex ratio was 0.75 for an average age of 38.2 ± 23.6 years. The circumstances of exposure were dietary for 337 patients (95.5%). The majority of the squash consumed was purchased at a store (55.8%) but some also came from the garden (25.5%). 204 patients (57.8%) mostly presented with diarrhea, vomiting, abdominal pain, sometimes with the consequent dehydration, hypotension, tachycardia, headaches, or vertigo. There were no deaths or severe (Poisoning Severity Score (PSS) 3) cases, but there were 14 patients (4.0%) of moderate severity, 190 patients (53.8%) of minor severity (PSS 1), and 149 patients (42.2%) without severity (PSS 0) but among which we include the bitter taste of the squash. The average age of PSS 2 patients was significantly (p = .003) older than that of the PSS <2 patients. CONCLUSION: As the first consequential series in Europe, our study shows that exposure to non-edible squash is frequent. Usually benign, poisoning could be the consequence of the irritating effect of certain cucurbits, the molecules responsible for the taste and toxicity of the fruits. In terms of prevention therefore, we recommend disposing of any squash with a bitter taste.

Main clinical, therapeutic and technical factors related to patient's maximum skin dose in interventional cardiology procedures.

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 389 mGy and 65 Gy cm(-2) for CAs, and 916 mGy and 69 Gy cm(-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 (r=0.93), 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.
