Laboratory features in acute paediatric poisoning with liquid laundry detergent capsules: a seven-year retrospective study in Romania.

INTRODUCTION: The epidemiological and clinical characteristics of acute poisoning with liquid laundry detergent capsules have been comprehensively reported. However, studies of laboratory test results in these exposures are uncommon. This study analyzed the impact of the ingestion of liquid laundry detergent capsules on admission laboratory tests in paediatric patients. METHODS: This retrospective study was conducted in the clinical toxicology unit of a paediatric poison centre between 2015 and 2021. Paediatric patients (less than 18 years of age) who ingested liquid laundry detergent capsules were included. The relationship between the European Association of Poisons Centers and Clinical Toxicologists/European Commission/International Programme on Chemical Safety Poisoning Severity Score and admission laboratory test results was assessed using Fisher's exact test or analysis of variance. RESULTS: A total of 156 patients were included in the study. A considerable proportion of patients presented with leucocytosis, acidosis, hyperlactataemia or base deficit. The median values of white blood cell count (P = 0.042), pH (P = 0.022), and base excess (P = 0.013) were significantly different among the Poisoning Severity Score groups. Hyperlactataemia was strongly associated with the Poisoning Severity Score (P = 0.003). DISCUSSION: Leucocytosis is a non-specific marker of severity following ingestion of liquid laundry detergent capsules. The incidence of metabolic acidosis and hyperlactataemia was higher in this study than in previous reports, but these metabolic features were not related to the severity of exposure. The exact mechanisms of toxicity are not yet known, but the high concentration of non-ionic and anionic surfactants, as well as propylene glycol and ethanol, in the capsule are likely contributing factors. CONCLUSIONS: Pediatric patients who ingest liquid laundry detergent capsules may develop leucocytosis, metabolic acidosis, hyperlactataemia, and a base deficit.

Dispersion of acid without gastric perforation on ingestion of toilet cleaner: a rare autopsy case.

Toilet cleaner containing hydrochloric acid is a common item found in households all over the world. Due to the availability of the substance, it becomes one of the main contributors to corrosive damage to the gastrointestinal system. This study reports a case of a female in her 50s with an alleged history of ingestion of toilet cleaner an empty bottle of which was found together with a suicide note at the incident site. During the autopsy, the forensic expert made an intriguing observation regarding the dispersion of ingested acid to other organs without gastric perforation. Despite the absence of gastric perforation, the corrosive effects of the ingested acid were evident in various organs, including the liver and spleen. This phenomenon suggests a unique mechanism by which the acid is able to disperse and cause damage beyond the stomach, leading to widespread organ involvement. However, through a comprehensive analysis of the detailed history, typical macroscopic autopsy findings, and chemical analysis reports, it is possible to establish that the cause of death is corrosive acid poisoning. In such cases, further investigation is warranted to gain a better understanding of the underlying mechanisms responsible for the dispersion of the acid and its clinical implications. By delving deeper into these aspects, we can enhance our knowledge and contribute to the field of forensic medicine.

Granular parakeratosis secondary to benzalkonium chloride exposure from common household laundry rinse aids.

AIM: Granular parakeratosis (GP) is a benign dermatosis characterised by a rash at intertriginous sites. The pathogenesis is uncertain although it is proposed to be an irritant contact reaction with cases related to benzalkonium chloride (BAC) reported. Our experience is that patients often have delayed diagnosis. This study aims to review the clinical presentation and histopathological features of GP. METHODS: This study is a retrospective case series of adult and paediatric patients seen at dermatology clinics in Auckland, New Zealand. Information was collected on patient demographics, presentation, investigations and management. RESULTS: Thirteen cases (seven adults; six children) are included. The typical presentation of GP was erythematous or brown, scaly papules and plaques with desquamation in a predominantly flexural distribution. All patients reported recent exposure to BAC in laundry rinse solution. Nine biopsies were taken from four patients. Psoriasiform and eczematous findings were common on histopathology. The mainstay of treatment was cessation of BAC exposure. CONCLUSION: GP has a distinct clinical pattern although histopathological findings are varied. Clinicians should have a high index of suspicion for GP in patients presenting with erythematous flexural eruptions and seek a history of BAC exposure, especially in the context of the COVID-19 pandemic and increased antiseptic use.

Geospatial correlation between COVID-19 health misinformation and poisoning with household cleaners in the Greater Boston Area.

INTRODUCTION: Calls to poison control about exposure to household cleaners have increased during the COVID-19 pandemic. This dynamic may reflect increased exposure from public health efforts as well as health misinformation shared on social media. METHODS: We analyzed the dynamics of calls to the Regional Center for Poison Control and Prevention serving Massachusetts and Rhode Island (MARI PCC) and tweets discussing treating COVID-19 with house cleaners from January 20, 2020 to May 5, 2020. We obtained publicly available tweets discussing the use of household cleaners to "cure COVID" from the same time period with geographic co-ordinates indicating that they were emitted from the Greater Boston Area. RESULTS: Our main finding is that public health efforts were followed by a sustained increase in calls after March 15, 2020 (10 ± 2 calls per day before to 15 ± 2.5 after) while misinformation on social media was associated with intermittent spikes in calls. Overall, calls significantly increased during the study period by 34% as compared to the previous 8 years, mostly reporting unintentional ingestions with no serious effects. The daily volume of tweets and retweets was significantly correlated with daily call rates to MARI PCC for the surrounding 7-10 days. CONCLUSIONS: Health misinformation on social media about using household cleaning agents to treat COVID-19 and public health efforts lead to different dynamics in PCC calls. Public health efforts were followed by a sustained increase in calls after March 15, 2020 while misinformation on social media was followed by intermittent spikes in calls. This analysis is the first to link the geospatial dynamics of social media and public health interventions to poison center calls about exposure to household cleaners.

The prevalence of esophageal cancer after caustic and pesticide ingestion: A nationwide cohort study.

Habits such as smoking and alcohol drinking and existing esophageal malfunction are considered the main risk factors for esophageal carcinogenesis. Caustic ingestion of acidic or alkaline agents or strong irritants can induce severe esophageal corrosive injury and increase esophageal cancer risk. We studied the relationship between esophageal carcinoma and acute detergent or pesticide poisoning by using nationwide health insurance data. Methodology/Principle findings: We compared a pesticide/detergent intoxication cohort (N = 21,840) and an age- and gender-matched control cohort (N = 21,840) identified from the National Health Insurance Research Database between 2000 and 2011. We used the multivariable Cox proportional model to determine esophageal carcinoma risk. The overall incidence density of esophageal cancer was 1.66 per 10,000 person-years in the comparison cohort and 4.36 per 10,000 person-years in the pesticide/detergent intoxication cohort. The corresponding adjusted hazard ratio (HR) for esophageal cancer was 2.33 (95% confidence interval [CI] = 1.41-3.86) in the pesticide/detergent intoxication cohort compared with the control cohort. Patients with corrosive and detergent intoxication did not have a higher risk of esophageal cancer (adjusted HR = 0.98, 95% CI = 0.29-3.33) than those without pesticide/detergent intoxication. However, patients with pesticide intoxication had a significantly higher risk of esophageal cancer (adjusted HR = 2.52, 95% CI = 1.52-4.18) than those without pesticide/detergent intoxication. Conclusion: In the present study, after adjusting for conventional risk factors, we observed that pesticide intoxication could exert substantial effects through increased esophageal cancer risk. However, patients with detergent intoxication may not have an increased risk of esophageal cancer.

The exploration of size and toddler interaction with liquid laundry detergent capsules.

Liquid laundry capsules have been involved in multiple poisoning incidents with young children in the home. There are a range of contributing factors for these incidents, including influences from industry, culture, home environments, and parenting/supervision. There also are influences from children's behaviour and decisions in reaction to potential hazards. Previous research examined the influence of capsule product appearance and colour on children's behaviour around hazardous household items, but little research examines the influence of product size. This research explored if differences in the size of liquid laundry capsules result in different levels of toddler interaction. We compared two commercially available capsule designs that are identical in physical appearance but differ in physical size. Our research was conducted using three studies: Study 1, forced-choice test in an out-of-context laboratory setting; Study 2, an ecologically-valid, simulated real-world setting replicating a home laundry cabinet with a container of capsules left open; and Study 3, a second ecologically-valid study replicating a home laundry cabinet, this time with a capsule left outside its container. Capsule interaction was measured by grasping choice among samples of 156 toddlers ages 9-36 months. The same sample was used for Studies 1 and 2, and a second identically sized sample recruited for Study 3. Results from Study 1 indicated toddlers selected the small (49.8% selection) and large (50.2%) capsule with nearly identical frequency. Study 2 largely replicated Study 1: Toddlers selected the small capsule or container of small capsules 26.8% of the time and the large capsule or container of large capsules 22.3% of the time. Study 3 also replicated previous findings: Toddlers selected the smaller capsule 18.0% of the time and the larger 19.2%. We discuss study results, which suggest no appreciable difference in toddler's grasping choice to smaller versus larger laundry capsules.

Knowledge and Practices Regarding Safe Household Cleaning and Disinfection for COVID-19 Prevention - United States, May 2020.

A recent report described a sharp increase in calls to poison centers related to exposures to cleaners and disinfectants since the onset of the coronavirus disease 2019 (COVID-19) pandemic (1). However, data describing cleaning and disinfection practices within household settings in the United States are limited, particularly concerning those practices intended to prevent transmission of SARS-CoV-2, the virus that causes COVID-19. To provide contextual and behavioral insight into the reported increase in poison center calls and to inform timely and relevant prevention strategies, an opt-in Internet panel survey of 502 U.S. adults was conducted in May 2020 to characterize knowledge and practices regarding household cleaning and disinfection during the COVID-19 pandemic. Knowledge gaps were identified in several areas, including safe preparation of cleaning and disinfectant solutions, use of recommended personal protective equipment when using cleaners and disinfectants, and safe storage of hand sanitizers, cleaners, and disinfectants. Thirty-nine percent of respondents reported engaging in nonrecommended high-risk practices with the intent of preventing SARS-CoV-2 transmission, such as washing food products with bleach, applying household cleaning or disinfectant products to bare skin, and intentionally inhaling or ingesting these products. Respondents who engaged in high-risk practices more frequently reported an adverse health effect that they believed was a result of using cleaners or disinfectants than did those who did not report engaging in these practices. Public messaging should continue to emphasize evidence-based, safe practices such as hand hygiene and recommended cleaning and disinfection of high-touch surfaces to prevent transmission of SARS-CoV-2 in household settings (2). Messaging should also emphasize avoidance of high-risk practices such as unsafe preparation of cleaning and disinfectant solutions, use of bleach on food products, application of household cleaning and disinfectant products to skin, and inhalation or ingestion of cleaners and disinfectants.

Exposures to Single-Use Detergent Sacs Reported to a Statewide Poison Control System, 2013-2015.

BACKGROUND: Single-use detergent sacs (SUDSs) represent a relatively new household hazard to children. Brand differences and packaging changes may contribute to differential risks with accidental exposure. We sought to identify high-risk features from SUDS exposures in children and to assess whether product packaging changed trends in SUDS exposures reported to poison centers. METHODS: In this institutional review board-approved, retrospective chart review of SUDS exposures from January 2013 to August 2015, deidentified case records of a large statewide poison control system were extracted and analyzed for clinical associations and trends. Clinical and demographic data were gathered, and outcomes were analyzed for differences by brand type, presenting complaints, and occurrence in relation to SUDS packaging changes. RESULTS: There were 3502 SUDS exposures, with 3343 (95%) in children 5 years or younger. Metabolic, central nervous system, and pulmonary effects were significantly associated with moderate or severe outcome (P < 0.05). Forty patients received invasive procedures such as endoscopy, bronchoscopy, and/or endotracheal intubation, and more than half had mucosal lesions discovered by the diagnostic procedure. The presence of stridor, wheezing, drooling, lethargy, and exposure to the brand All Mighty Pacs were all significant predictors of moderate or severe outcome (P < 0.05). After the implementation of packaging changes, there was a transient decline in the number of exposures to the Tide Pods product. CONCLUSION: Central nervous system and respiratory effects as well as certain brand types predict serious outcomes from SUDS exposures. Manufacturing changes had a brief beneficial effect on the volume of SUDS exposures reported between 2013 and 2015.

Safety Interventions and Liquid Laundry Detergent Packet Exposures.

OBJECTIVES: To investigate exposures to liquid laundry detergent packets among children <6 years old in the United States and to evaluate the impact of the American Society for Testing and Materials voluntary product safety standard. METHODS: Data from the National Poison Data System involving exposures to liquid laundry detergent packets from 2012 to 2017 were analyzed. RESULTS: From January 2012 to December 2017, there were 72 947 single and polysubstance exposures to liquid laundry detergent packets. Most exposures (91.7%) were documented among children <6 years old. The annual number and rate of exposures for children <6 years old increased by 110.4% and 111.9%, respectively, from 2012 to 2015. From 2015 to 2017, the number and rate of exposures in this age group decreased by 18.0%. Among individuals ≥6 years old, the annual number and rate of exposures increased by 292.7% and 276.7%, respectively, from 2012 to 2017. Annual hospital admissions among children <6 years old increased by 63.4% from 2012 to 2015 and declined by 55.5% from 2015 to 2017. Serious outcomes among children <6 years old increased by 78.5% from 2012 to 2015 and declined by 32.9% from 2015 to 2017. CONCLUSIONS: The number, rate, and severity of liquid laundry detergent packet exposures have decreased modestly in recent years among children <6 years old, likely attributable, in part, to the voluntary product safety standard and public awareness efforts. Exposures among older children and adults are increasing. Opportunities exist to strengthen the current product safety standard to further reduce exposures.

Liquid laundry detergent capsules (PODS): a review of their composition and mechanisms of toxicity, and of the circumstances, routes, features, and management of exposure.

Introduction: Liquid laundry detergent capsules (also called single-use detergent sacs; laundry pods; laundry packets) have become an increasingly popular household product worldwide. Objectives: To review the composition and mechanisms of toxicity of liquid laundry detergent, capsules, and the circumstances, routes, clinical features (and impact of packaging changes) and management of exposure. Methods: The databases PubMed and EMBASE were searched using the terms: "detergent" and "capsule", "pod", "pac" or "sac" combined with "poison", "ingest", "expos" but not "animal" or "in vitro" or "bacteria". The searches yielded 289 articles, of which 186 were excluded: 38 duplicates, 133 not relevant, 10 abstracts which had been published as a paper and 5 non-English language articles. The bibliographies of relevant articles were hand-searched which yielded 14 additional citations. Searching of abstracts from scientific meetings produced five additional citations. A total of 122 publications were relevant to the objectives of the review. Capsules and composition: Capsules typically contain anionic surfactants (20-35%), non-ionic surfactants (10-20%), propylene glycol (8-20%) and ethanol (2-5%) within a water-soluble polyvinyl alcohol membrane. Mechanisms of toxicity: Non-ionic surfactants are the primary mechanism, though anionic surfactants, ethanol and propylene glycol may also contribute. Circumstances of exposure: The majority (60%) of children are exposed when the capsule is removed from its original container. Routes of exposure: Ingestion is the most common (>85%); ocular (<15%) and dermal (<8%) exposure account for the remainder. Features following ingestion: Features develop in around half of all exposures, though >90% are minor. In those with features, vomiting occurs in some 50%; coughing and drowsiness are reported in <5%. Respiratory depression (<0.5%), central nervous system depression (<0.1%) esophageal or gastric injury (<0.5%), metabolic acidosis and hyperlactatemia (<0.05%) have been reported rarely. Of 17 deaths reported, 13 were adults and nine were suffering from cognitive impairment. Features following ocular exposure: Conjunctivitis, eye irritation and/or eye pain are commonly experienced; corneal injury is less common but complete recovery typically occurs within one week. Features following dermal exposure: Clinically important dermal toxicity seldom occurs, though skin burns can develop in <5% of cases when skin contact is prolonged. Impact of packaging changes on features: The implementation of packaging changes resulted in a fall in the number of exposures and their severity in the United States and in the number in Italy. Management-ingestion: Gut decontamination is not recommended, though small amounts of fluid can be administered orally to rinse out the mouth. Symptomatic and supportive care should be offered to all patients that develop features of toxicity. Supplemental oxygen should be administered for hypoxemia, and bronchodilators for laryngospasm/bronchospasm. Intubation and assisted ventilation may be required if CNS and respiratory depression develop. A chest radiograph should be performed if respiratory features develop. In patients with swallowing difficulties, drooling or oropharyngeal burns, endoscopy should be performed; if substantial mucosal damage is present MRI should be considered. In addition, intravenous fluids will be required if prolonged vomiting or diarrhea occur and acid-base disturbances should be corrected. Management-eye exposure: Thorough irrigation of the eye with sodium chloride 0.9% is required. Instillation of a local anesthetic will reduce discomfort and help more thorough decontamination. Due to the potential for corneal injury, fluorescein should be instilled. If ocular injury is present, the patient should be referred to an ophthalmologist. Management-skin exposure: Skin should be irrigated thoroughly with soap and water, and burns should be treated as a thermal burn. Conclusions: Accidental ingestion usually produces no or only minor features. Very rarely respiratory depression, central nervous system depression, esophageal or gastric injury, hyperlactatemia and metabolic acidosis occur. Ocular exposure results in corneal injury infrequently and skin burns can develop uncommonly following prolonged dermal contact. Of 17 deaths reported, 13 were adults and nine were suffering from cognitive impairment.

A review of 4652 exposures to liquid laundry detergent capsules reported to the United Kingdom National Poisons Information Service 2008-2018.

Introduction: Liquid laundry detergent capsules contain concentrated liquid laundry detergent in a water-soluble polyvinyl alcohol membrane.Objective: To review 4652 exposures reported to the United Kingdom National Poisons Information Service (NPIS) and to assess the impact of regulatory changes on potential toxicity.Methods: Telephone enquiries to the NPIS and returned questionnaires for these products were analyzed for the period January 2008 to December 2018.Results: Data on 4652 exposures were reported by telephone or questionnaire, of which 95.4% involved children aged ≤5 years. Overall, 1738 of 4594 patients remained asymptomatic (Poisoning Severity Score [PSS] 0), 2729 developed minor (PSS 1) features, 107 suffered moderate features (PSS 2), 19 were graded as severe (PSS 3) and one died. Ingestion was involved in most exposures (n = 4175): vomiting occurred in 46.5%, coughing occurred in 4.3% and central nervous system depression in 3.2%. Nine (0.2%) children were intubated and ventilated. The eye was exposed in 646 cases: 371 (59.8%) suffered conjunctivitis or eye irritation and 21 (3.4%) had keratitis/corneal damage, which persisted in one patient for 9 d. The skin was involved in 364 cases; in 127 (35.5%) minor dermal features developed including erythema, irritation and rash. The most commonly reported features in the 127 cases with PSS ≥2 were vomiting (n = 75), stridor (n = 34), CNS depression (n = 22), keratitis/corneal damage (n = 21), coughing (n = 18), conjunctivitis (n = 13), hypersalivation (n = 12), foaming from the mouth (n = 11) and hypoxemia (n = 11). However, respiratory features (stridor, hypoxemia, bronchospasm, respiratory distress, dyspnea, pulmonary aspiration and tachypnea) were the reason for grading 56 of 127 cases as PSS ≥2.Conclusions: This large data set of 4652 exposures is reassuring in that 97.2% of exposures resulted in no or only minor features, only 107 patients suffered moderate features (PSS 2) and 19 severe (PSS 3) features; one patient died.

Prospective analysis of pediatric ocular chemical burns: laundry detergent pods.

PURPOSE: To present data on chemical ocular burns in children seen at a single tertiary care facility resulting from accidental eye exposure to the contents of laundry detergent pods. METHODS: All emergent pediatric ophthalmology consultations specific for chemical ocular burns at a level I trauma center were included as part of a prospective quality improvement investigation over a 13-month period. Age, causative agent, and examination findings at presentation and final follow-up were recorded and analyzed. RESULTS: A total of 12 children with chemical ocular burns were seen during the study period. All patients were ≤5 years of age. Most chemical ocular burn consultations (n = 8) were specific to ocular exposure of laundry detergent pod contents; the remainder were associated with conventional cleaning agents or pesticides (n = 4). There was a significant association between laundry detergent pod as causative agent and a patient age of 2-5 years, compared to <2 years and any other agent (P = 0.018 [Fisher exact test]). CONCLUSIONS: In our study, laundry detergent pods were the most frequent cause of chemical ocular burns in children. Additionally, preschoolers may be at a higher risk of sustaining these injuries. Increased public awareness, product safety improvements, and/or regulation may be advisable to decrease the ocular hazards associated with laundry detergent pods.

Single-Use Laundry Detergent Pack Exposures in Children Under 6 Years: A Prospective Study at U.S. Poison Control Centers.

BACKGROUND: After the widespread introduction of single-use liquid laundry detergent packs (LLDPs), a prospective observational study was initiated among 12 U.S. poison control centers (PCCs), serving 25% of the population. OBJECTIVES: To evaluate qualitative and quantitative data, including demographics, route of exposure, clinical effects, medical outcome, management site, level of care, and circumstantial variables surrounding the LLDP exposure. METHODS: Analysis of LLDP exposures involving children (age < 6 years) reported to PCCs participating in the prospective study (March 2012-February 2016). PCCs captured a detailed exposure history and followed each patient to symptom resolution. Each case narrative was reviewed to isolate key patient, product, and situational variables and to verify accuracy of coded data. Trend and comparative analyses were performed on absolute case counts, relative proportions, and reporting rates normalized using Nielsen consumption data. Separately, the impact of exposure reduction interventions introduced by a single manufacturer were assessed by comparing reporting rate during pre-/postintervention periods. RESULTS: There were 11,175 childhood exposures reported, with 90.3% involving children aged ≤ 3 years. Ingestion (82.6%) and ocular (14.2%) were the major routes of exposure. The size of the market for LLDPs more than doubled from ∼2.0 to ∼4.6 million LLDPs purchased. Total exposure reports increased from Year 1 (n = 2297) to Year 4 (n = 3206), however, normalized reporting rates dropped by 37% (4.4 to 2.8 exp/million LLDPs purchased). Significant declines (p < 0.0001) were also observed for ingestions and ocular exposures with major/moderate outcome. CONCLUSIONS: There was a significant reduction in exposures that resulted in major/moderate outcomes, and the majority of patients did not require intervention in an emergency department setting.

Exposures to automatic dishwashing rinse aids reported to the United Kingdom National Poisons Information Service 2008-2016.

OBJECTIVE: To determine the toxicity of rinse aids which are used as drying aids to remove water from crockery. METHODS: Enquiries to the UK National Poisons Information Service (NPIS) were analysed retrospectively for the period January 2008 to December 2016. RESULTS: There were 855 enquiries relating to 828 patients; children aged 5 years or less accounted for 91.1%. Most exposures occurred from ingestion alone (n = 778, 94.0%), but 26 involved ingestion and other routes: 21 with skin contact, 3 with eye contact, and two with both skin and eye contact. There were a further 24 cases of eye contact alone (n = 20, 2.4%) or skin contact alone (n = 3, 0.4%) and a single case of inhalation alone. The World Health Organisation/International Programme on Chemical Safety/European Commission/European Association of Poison Centres and Clinical Toxicologists (WHO/IPCS/EC/EAPCCT) Poisoning severity score [PSS] was known in 824 of the 828 exposures: 425 of 824 (51.6%) patients did not develop clinical features, 381 (46.2%) had a PSS of 1 (minor toxicity), 15 (1.8%) developed moderate (PSS 2) and 3 (0.4%) severe (PSS 3) toxicity. Vomiting was the most common feature, occurring in over a third of all ingestions (n = 286, 35.8%), followed by coughing (n = 73, 9.1%). A higher proportion of adults than children developed clinical features (72.7% of 33 vs 46.0% of 767, p = .0026), although vomiting occurred significantly more frequently amongst children (p = .0315). Of the 25 eye contact cases, eye pain (n = 8) and/or eye irritation (n = 8) were reported, with or without abnormal vision (n = 7); there were two cases of corneal abrasion. Dermal contact rarely produced features; only 4 of 26 patients reported symptoms including skin rash or burning or numbness at the contact site. CONCLUSIONS: Severe clinical features were uncommon following rinse aid exposure; vomiting was the most frequently reported symptom following ingestion.

Surveillance of paediatric exposures to liquid laundry detergent pods in Italy.

OBJECTIVE: To analyse paediatric exposures to pod and traditional laundry detergents in Italy and changes in exposure trends. METHODS: Analyses of a series of patients aged <5 years and exposed to laundry detergents between September 2010 and June 2015, identified by the National Poison Control in Milan. RESULTS: In comparison with patients exposed to traditional laundry detergents (n=1150), a higher proportion of those exposed to pods (n=1649) were managed in hospital (68% vs 42%), had clinical effects (75% vs 22%) and moderate/high severity outcomes (13% vs <1%). Exposure rates were stable over time for traditional detergents (average 0.65 cases/day), but an abrupt decline in major company pods was seen in December 2012, 4 months after the introduction of opaque outer packaging (from 1.03 to 0.36 cases/day and from 1.88 to 0.86 cases/million units sold). The odds of clinical effects was higher for exposure to pods than for traditional detergents (OR=10.8; 95% CI 9.0 to 12.9). Among patients exposed to pods, the odds of moderate/high severity outcomes was four times higher for children aged <1 years than for the other age groups (OR=3.9; 95% CI 2.2 to 7.0). Ten children exposed to laundry detergent pods had high severity outcomes while no children exposed to traditional laundry detergents developed high severity effects. CONCLUSIONS: The study confirms that exposure to laundry detergent pods is more dangerous than exposure to traditional detergents. In Italy, 4 months after the introduction of opaque outer packaging by a major company, product-specific exposure rates decreased sharply, suggesting that reducing visibility of laundry detergent pods may be an effective preventive measure. Further efforts are needed to improve safety.

Single-Use Detergent Sacs: A Retrospective Multicenter Canadian Review of Emergency Department Cases.

BACKGROUND: Single-use detergent sacs (SUDS) are widely used in North America and Europe with emerging literature on their toxicity. This is the first Canadian multicenter study aimed to quantify and compare SUDS exposures to traditional detergent exposures. METHODS: A retrospective review of the Canadian Hospitals Injury Reporting and Prevention Program databases was conducted at the Hospital for Sick Children in Toronto, Alberta Children's Hospital in Calgary and the Stollery Children's Hospital in Edmonton. All exposures presenting to these 3 centers between 2009 and 2014 were identified, a case form was completed, and data were analyzed. RESULTS: Forty cases of SUDS exposure were identified alongside 35 cases of traditional detergent exposure during the study period resulting in an incidence of 3.16 SUDS exposures per million children per year presenting to tertiary pediatric emergency departments (EDs). In contrast, traditional detergent exposures had an incidence of 2.78 exposures per million children per year presenting to tertiary pediatric EDs over the study period. Although there was no change in incidence of exposure to traditional detergent over the study period, there was an increase in the incidence of SUDS exposures from 2010 to 2013, with a decrease seen in 2014. There was no significant difference seen in age, sex, location of exposure, transportation to hospital, morbidity, or mortality associated with SUDS exposures compared with traditional detergent exposure. Although not statistically more likely to cause long-term complications, SUDS-exposed children required more follow-up visits to health care providers than traditional detergents. CONCLUSIONS: This multicenter study is the first to establish the incidence of SUDS and traditional detergent exposure in 3 Canadian cities. Overall, the frequency of exposure to detergents-both traditional and SUDS-is very low. Given the increase in SUDS exposure seen from 2011 to 2013, alongside larger sales of SUDS, continued efforts are required to monitor exposures, and reduce potential exposures to SUDS and traditional detergents in the future.
