ABSTRACT
Ceramic and metal hair straightening and curling irons are common household items which reach up to 450°F in as little as five seconds. Of particular concern is the threat these devices pose to children. Our objective is to characterize and bring attention to this preventable injury in the pediatric population. Retrospective records from a high-volume level I trauma center and regional burn center from 2011-2015 were analyzed. Inclusion criteria were defined as patients <11 years of age, as those presenting with burns above this age were more likely to be utilizing the tools for hair styling. A total of 59 patients were identified with an average age of 2.4 years. The average burn size was 0.30%, with an average 0.24% 2nd degree TBSA. The etiology of the burns included touching a hair iron that was within reach (61%), pulling a hair iron's power cord (15%), stepping/rolling/jumping onto a hair iron left on the ground (17%), and hair irons falling (7%). The majority of households were comprised of unemployed (64%), single (60%) parents. CPS consult was required for 20% of patients. Grafting and excision was necessary for 20% of patients The pediatric population is at risk for accidental burns with household hair irons. These burns typically have a small TBSA, but may require excision and grafting and extended follow-up.
Les lisseurs et fers à friser, en céramique ou en métal, sont des objets courants au domicile. Leur température peut monter à plus de 230°C en quelques secondes. Le risque qu'encourent les enfants est préoccupant. Nous avons explorés ces brûlures afin de déterminer des stratégies de prévention. Nous avons analysé rétrospectivement les données d'un CTB régional, recueillies entre 2011 et 2015. Nous n'avons retenu que les brûlures atteignant les enfants de 11 ans au maximum (59 cas, âge moyen 2,4 ans), les enfants plus âgés étant susceptibles d'utiliser ces instruments à leur propre bénéfice. La surface brûlée était de 0,3 % dont 0,24 % de 2ème degré. La brûlure était consécutive au toucher d'un ustensile atteignable (61%), à la traction sur le cordon d'alimentation (15%), à la marche dessus (17%), à la chute de l'objet (7%). Les familles concernées étaient en majorité monoparentales (60%) sans emploi (64%). Les services de protection de l'enfance ont été sollicités dans 20% des cas. Les enfants sont particulièrement à risque de brûlures lors d'accidents domestiques, pouvant impliquer des fers à friser et des lisseurs. Ces brûlures sont typiquement peu étendues mais peuvent être profondes, nécessiter une greffe et un suivi prolongé.
ABSTRACT
The objective of this study was to identify the factors associated with important clinical outcomes in a case-control study of 213 patients with lupus nephritis. Included were 47% Hispanics, 44% African Americans and 9% Caucasians with a mean age of 28 years. Fifty-four (25%) patients reached the primary composite outcome of doubling serum creatinine, end-stage renal disease or death during a mean follow-up of 37 months. Thirty-four percent African Americans, 20% Hispanics and 10% Caucasians reached the primary composite outcome (P < 0.05). Patients reaching the composite outcome had predominantly proliferative lupus nephritis (WHO classes: 30% III, 32% IV, 18% V and 5% II, P < 0.025) with higher activity index score (7 +/- 6 versus 5 +/- 5, P < 0.05), chronicity index (CI) score (4 +/- 3 versus 2 +/- 2 unit, P < 0.025), higher baseline mean arterial pressure (MAP) (111 +/- 21 versus 102 +/- 14 mmHg, P < 0.025) and serum creatinine (1.9 +/- 1.3 versus 1.3 +/- 1.0 mg/dL, P < 0.025), but lower baseline hematocrit (29 +/- 6 versus 31 + 5%, P < 0.025) and complement C3 (54 +/- 26 versus 65 + 33 mg/dL, P < 0.025) compared to controls. More patients reaching the composite outcome had nephrotic range proteinuria compared to controls (74% versus 56%, P < 0.025). By multivariate analysis, CI (hazard ratio [95% CI] 1.18 [1.07-1.30] per point), MAP (HR 1.02 [1.00-1.03] per mmHg), and baseline serum creatinine (HR 1.26 [1.04-1.54] per mg/dL) were independently associated with the composite outcome. We concluded that hypertension and elevated serum creatinine at the time of the kidney biopsy as well as a high CI are associated with an increased the risk for chronic renal failure or death in patients with lupus nephritis.
