Exposures and Suspected Intoxications to Pharmacological and Non-Pharmacological Agents in Children Aged 0-14 Years: Real-World Data from an Italian Reference Poison Control Centre.

This study describes the exposures and suspected intoxications in children (0-14 years) managed by an Italian reference poison control center (PCC). A seven-year observational retrospective study was performed on the medical records of the Toxicology Unit and PCC, Careggi University Hospital, Florence (Italy). During the study period (2015-2021), a total of 27,212 phone call consultations were managed by the PCC, of which 11,996 (44%) involved subjects aged 0-14 years. Most cases occurred in males (54%) aged 1-5 years (73.8%), mainly at home (97.4%), and with an oral route of intoxication (93%). Cases mainly occurred involuntarily. Consultations were generally requested by caregivers; however, in the age group 12-14 years, 70% were requested by healthcare professionals due to voluntary intoxications. Cleaners (19.44%) and household products (10.90%) were the most represented suspected agents. Pharmacological agents accounted for 28.80% of exposures. Covariates associated with a higher risk of emergency department visit or hospitalization were voluntary intoxication (OR 29.18 [11.76-72.38]), inhalation route (OR 1.87 [1.09-3.23]), and pharmacological agents (OR 1.34 [1.23-1.46]), particularly central nervous system medications. Overall, consultations do not burden national and regional healthcare facilities, revealing the activity of PCCs as having a strategic role in reducing public health spending, even during the COVID-19 pandemic.

Exposures and suspected intoxications during SARS-CoV-2 pandemic: preliminary results from an Italian poison control centre.

Data on cleaner and disinfectant exposure and misuse-related acute intoxications in Italy during SARS-CoV-2 pandemic are still lacking. The aim of the present study was to analyse and describe cleaner and disinfectant-related intoxications during SARS-CoV-2 pandemic in an Italian poison control centre. Data were obtained from the toxicological consultations requested to the Toxicology Unit and Poison Centre, Careggi University Hospital, Florence (Italy). We compared data from January 1st to April 30th of 2019 and 2020. Data concerning probable or acute intoxication from any causative agent in the general population (all age groups), from private individuals or from Regional and National health structures, were included in the analysis. A toxicological evaluation was also performed to calculate the Poisoning Severity Score.In 2019, 451 phone counselling sessions were performed and compared to a total of 410 calls received during the same period of 2020. In both periods, the majority of events occurred in paediatric (0-17 years) and adult (18-65 years) patients, who were mainly exposed to one toxic agent, and intoxications took place principally at home due to domestic accidents. The oral route of intoxication was the most frequently observed one, followed by inhalation of toxic agents, which increased by 4.7% in 2020. In 2020, sanitizers and cleaners were reported in 21.6% of cases compared to 12.5% in 2019. This is the first study describing cleaner and disinfectant-related intoxications in Italy. Our results suggested a possible misuse of these products during the SARS-CoV-2 pandemic, underling the effects of home isolation on mental health and unintentional toxic exposures.

Adverse drug reactions in SARS-CoV-2 hospitalised patients: a case-series with a focus on drug-drug interactions.

Due to the need of early and emergency effective treatments for COVID-19, less attention may have been paid to their safety during the global emergency. In addition, characteristics of drug-drug interaction (DDI)-related adverse drug reactions (ADRs) in COVID-19 patients have not yet been studied in depth. The aim of the present case-series study is to describe clinical and pharmacological characteristics of SARS-CoV-2 hospitalised patients, focusing on ADRs, particularly those related to DDIs. We evaluated all reports of COVID-19 medication-related ADRs collected within the COVID-19 Units of Careggi University Hospital, Florence (Italy), between January 1st and 31st May 2020. Information regarding COVID-19 medications, patients' demographic and clinical characteristics, concomitant drugs, ADRs description and outcome, were collected. Each case was evaluated for the causality assessment and to identify the presence of DDIs. During the study period, 23 Caucasian patients (56.5% males, mean age 76.1 years) experienced one or more ADRs. The majority of them were exposed to polypharmacy and 17.4% presented comorbidities. ADRs were referred to cardiovascular, psychiatric and gastrointestinal disorders. The most frequently reported preferred term was QT prolongation (mean QT interval 496.1 ms). ADRs improved or resolved completely in 60.8% of cases. For all patients, a case-by-case evaluation revealed the presence of one or more DDIs, especially those related to pharmacokinetic interactions. Despite the small number of patients, our evidence underline the clinical burden of DDIs in SARS-CoV-2 hospitalised patients and the risk of unexpected and uncommon psychiatric ADRs.

Pregnancy outcome following exposure to topical retinoids: a multicenter prospective study.

Concerns have been raised about the use of topical retinoids since the publication of isolated cases of characteristic retinoid embryopathy, originally described after oral use. A collaborative study of the European Network of Teratology Information Services was carried out to evaluate the rate of congenital malformations following first-trimester topical retinoid exposure. A population of 235 exposed pregnant women was compared with 444 controls. No significant differences were observed between groups with regard to the rates of spontaneous abortion (odds ratio [95% confidence interval], 1.5 [0.8-2.7]), minor birth defects (1.3 [0.4-3.7]), and major birth defects (1.8 [0.6-5.4]). No child showed features of retinoid embryopathy. The rate of elective termination in the exposed group was increased 3-fold (3.4 [1.5-7.8]). In conclusion, these results do not suggest an increased risk of retinoid embryopathy. However, according to current knowledge, topical retinoids cannot be advised for use during pregnancy because their risk/benefit ratio remains questionable.
