Patterns and Emerging Trends in Acute Poisoning with Substances of Abuse Used for Recreational Purposes in Adolescents: A Six-Year Multicentre Study.

This six-year multicentre study investigated acute intentional poisoning with substances of abuse in adolescents to identify changes and patterns in substance use. Data from 562 adolescents were collected from three paediatric poison centres in Romania between January 2017 and December 2022. This study analysed the epidemiological and sociodemographic characteristics of the adolescents, including age, gender, place of residence, history of substance abuse, psychiatric history, and history of institutionalised care. The findings revealed that cannabis and new psychoactive substances (NPSs) are the most commonly implicated substances, each with distinct profiles among adolescents. Cannabis was involved in 46.1% of cases, with a significant association with urban residency. NPSs were identified as the second most prevalent substance, accounting for 39.3% of cases. These were more prevalent in rural areas and among patients with psychiatric disorders. Cannabis and NPSs were also the most commonly implicated substances in acute intentional poisoning cases with substances of abuse. These substances have distinct profiles among adolescents, including age, gender, residency area, history of substance abuse, psychiatric history, and institutional care. These findings underscore the necessity of targeted public health interventions and integrated care approaches to address substance use and related mental health issues in adolescents.

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.

Neurological Manifestations of Acute SARS-CoV-2 Infection in Pediatric Patients: A 3-Year Study on Differences between Pandemic Waves.

This study analyzed the neurological manifestation profiles of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection across pandemic waves in pediatric patients. The study collected data on patients aged between 0 and 18 years, diagnosed with acute SARS-CoV-2 infection, admitted to a pediatric tertiary hospital between 1 March 2020 and 28 February 2023. This study included 1677 patients. Neurological manifestations were noted in 10% (n = 168) of patients with a median age of 3.2 years (interquartile range: 1-11.92). Neurological manifestations were significantly associated with the pandemic waves (p = 0.006) and age groups (p < 0.001). Seizures were noted in 4.2% of cases and reached an increasing frequency over time (p = 0.001), but were not associated with age groups. Febrile seizures accounted for the majority of seizures. Headache was reported in 2.6% of cases and had similar frequencies across the pandemic waves and age groups. Muscular involvement was noted in 2% of cases, reached a decreasing frequency over time (p < 0.001), and showed different frequencies among the age groups. Neurological manifestations of acute SARS-CoV-2 infection exhibit distinct patterns, depending on the pandemic wave and patient age group. The Wuhan and Omicron waves involved the nervous system more often than the other waves.

Epidemiology and Clinical Characteristics of Acute Plant Exposure in Patients Aged between 0 and 18 Years-A Six-Year Retrospective Study.

BACKGROUND: Exposure to plants accounts for approximately 5% of human poisoning cases reported by poison control centers in North America and Europe. The aim of this study was to investigate acute plant poisoning in patients aged 0-18 years admitted to a Romanian pediatric poison center, focusing on epidemiological and clinical aspects. METHODS: A retrospective observational study was conducted between 2017 and 2022, analyzing medical records for demographic information, clinical features, biological findings, and outcomes. Statistical analysis was performed using Microsoft Excel. RESULTS: 71 patients (aged 7 months to 16 years) presented with acute plant poisoning. Most cases were unintentional (92.9%), peaking during the autumn season. Colocasia (18.3%), Dieffenbachia (9.8%), and Ricinus (5%) were the most frequently involved plants. Gastrointestinal symptoms, especially vomiting, predominated. The Poisoning Severity Score classified most cases as mild (52.1%), with no severe or fatal cases. The mean length of hospitalization was 1.8 days. CONCLUSIONS: Unintentional plant exposure, mainly in children under 5 years of age, accounted for more than 90% of cases. Gastrointestinal exposure and symptoms were prevalent, and treatment consisted mainly of symptomatic and supportive measures. Severe and fatal cases were rare, highlighting the generally favorable outcome and low incidence of severe poisoning in the pediatric population.

Use of Lung Ultrasound in Reducing Radiation Exposure in Neonates with Respiratory Distress: A Quality Management Project.

Background and Objectives: Our quality management project aims to decrease by 20% the number of neonates with respiratory distress undergoing chest radiographs as part of their diagnosis and monitoring. Materials and Methods: This quality management project was developed at Life Memorial Hospital, Bucharest, between 2021 and 2023. Overall, 125 patients were included in the study. The project consisted of a training phase, then an implementation phase, and the final results were measured one year after the end of the implementation phase. The imaging protocol consisted of the performance of lung ultrasounds in all the patients on CPAP (continuous positive airway pressure) or mechanical ventilation (first ultrasound at about 90 min after delivery) and the performance of chest radiographs after endotracheal intubation in any case of deterioration of the status of the patient or if such a decision was taken by the clinician. The baseline characteristics of the population were noted and compared between years 2021, 2022, and 2023. The primary outcome measures were represented by the number of X-rays performed in ventilated patients per year (including the patients on CPAP, SIMV (synchronized intermittent mandatory ventilation), IPPV (intermittent positive pressure ventilation), HFOV (high-frequency oscillatory ventilation), the number of X-rays performed per patient on CPAP/year, the number of chest X-rays performed per mechanically ventilated patient/year and the mean radiation dose/patient/year. There was no randomization of the patients for the intervention. The results were compared between the year before the project was introduced and the 2 years across which the project was implemented. Results: The frequency of cases in which no chest X-ray was performed was significantly higher in 2023 compared to 2022 (58.1% vs. 35.8%; p = 0.03) or 2021 (58.1% vs. 34.5%; p = 0.05) (a decrease of 22.3% in 2023 compared with 2022 and of 23.6% in 2023 compared with 2021). The frequency of cases with one chest X-ray was significantly lower in 2023 compared to 2022 (16.3% vs. 35.8%; p = 0.032) or 2021 (16.3% vs. 44.8%; p = 0.008). The mean radiation dose decreased from 5.89 Gy × cm2 in 2021 to 3.76 Gy × cm2 in 2023 (36% reduction). However, there was an increase in the number of ventilated patients with more than one X-ray (11 in 2023 versus 6 in 2021). We also noted a slight annual increase in the mean number of X-rays per patient receiving CPAP followed by mechanical ventilation (from 1.80 in 2021 to 2.33 in 2022 and then 2.50 in 2023), and there was a similar trend in the patients that received only mechanical ventilation without a statistically significant difference in these cases. Conclusions: The quality management project accomplished its goal by obtaining a statistically significant increase in the number of ventilated patients in which chest radiographs were not performed and also resulted in a more than 30% decrease in the radiation dose per ventilated patient. This task was accomplished mainly by increasing the number of patients on CPAP and the use only of lung ultrasound in the patients on CPAP and simple cases.

Benzalkonium Chloride Poisoning in Pediatric Patients: Report of Case with a Severe Clinical Course and Literature Review.

The use of disinfectants, particularly those containing quaternary ammonium compounds (QUACs), has dramatically escalated globally since the coronavirus disease 2019 pandemic. We report a case that highlights the risks associated with ingesting low-concentration QUAC solutions and emphasize the importance of effective management in resolving severe lesions without sequelae. A 17-month-old boy experienced severe respiratory failure after ingesting a disinfectant containing benzalkonium chloride (BAC). The child was initially treated at a local emergency department and was subsequently transferred to a pediatric poison center. Upon evaluation, the child was found to have grade III-A corrosive esophageal lesions and chemical pneumonitis. Several complications, including massive pneumothorax and candidemia, occurred during the clinical course of the disease. However, with timely medical intervention and appropriate supportive care, the patient completely recovered without any long-term sequelae. The properties of BAC and the comprehensive management approach may have been responsible for the patient's full recovery, despite the potentially life-threatening effects of ingesting disinfectants.

Neurotoxicity and Other Clinical Manifestations of a Common European Adder (Vipera berus) Bite in Romania.

Most cases of envenomation by common European vipers (Vipera berus) have not been reported to have neurotoxic manifestations. However, these manifestations have been demonstrated in some cases of envenomation by subspecies of V. berus, found in the Carpathian Basin region of south-eastern Europe. Here, we report the case of a 5-year-old girl from the south of Romania who presented symptoms of neurotoxicity, as well as other systemic and local symptoms, after being bitten by an adder of the V. berus subspecies. Treatment consisted of monovalent antivenom, a corticosteroid, and prophylactic enoxaparin. Neurotoxic manifestations of envenomation as well as other local and systemic symptoms improved within 5 days of treatment. The presented case shows that venom from V. berus subspecies found in the Carpathian Basin can have neurotoxic effects. This case also confirmed the efficacy of monospecific antivenom treatment in bringing about rapid and complete remission, following envenomation.

Acute liver failure secondary to toxic exposure in children.

INTRODUCTION: Acute liver failure (ALF) is a syndrome defined by jaundice, coagulopathy (INR > 1.5) and hepatic encephalopathy in patients with no evidence of prior liver disease. Toxins and drugs are a frequent cause of ALF in children. MATERIAL AND METHODS: The aim of our study was to establish the causes of toxic ALF in children followed up in our hospital in the period of January 2000 to August 2018. We retrospectively studied all hospital records of patients who developed ALF after mushroom/drug exposure and had been admitted to our hospital, the main pediatric toxicology center in north-western Romania. RESULTS: In the last 18 years, 123 patients were admitted to our clinic with toxic ALF (89 patients secondary to mushroom ingestion and 34 patients after drug exposure). In the 2000-2012 period accidental mushroom poisoning was the leading cause of toxic ALF. Unfortunately, during the last years, voluntary drug ingestions have increased dramatically. The most commonly incriminated drug was acetaminophen (52.94%). CONCLUSIONS: ALF in mushroom poisoning is associated with a high mortality in children, despite optimal medical therapy. This etiology was one of the most important causes of death in our cohort. The difficulty in accessing emergency liver transplantation is an obstacle common to many Eastern European pediatric centers. Fortunately, in the last 5 years the incidence of mushroom intoxications has decreased in our area. It is worrying that over the last few years there has been an increased incidence of toxic ALF after drug exposure (for suicidal purposes or due to lenient regulations for prescribing hepatotoxic medications).

The Role of Predictive Models in the Assessment of the Poor Outcomes in Pediatric Acute Liver Failure.

OBJECTIVES: In children, acute liver failure (ALF) is a severe condition with high mortality. As some patients need liver transplantation (LT), it is essential to predict the fatal evolution and to refer them early for LT if needed. Our study aimed to evaluate the prognostic criteria and scores for assessing the outcome in children with ALF. METHODS: Data of 161 children with ALF (54.66% female, mean age 7.66 ± 6.18 years) were analyzed based on final evolution (32.91% with fatal evolution or LT) and etiology. We calculated on the first day of hospitalization the PELD score (109 children), MELD, and MELD-Na score (52 children), and King's College Criteria (KCC) for all patients. The Nazer prognostic index and Wilson index for predicting mortality were calculated for nine patients with ALF in Wilson's disease (WD). RESULTS: PELD, MELD, and MELD-Na scores were significantly higher in patients with fatal evolution (21.04 ± 13.28 vs. 13.99 ± 10.07, p = 0.0023; 36.20 ± 19.51 vs. 20.08 ± 8.57, p < 0.0001; and 33.07 ± 8.29 vs. 20.08 ± 8.47, p < 0.0001, respectively). Moreover, age, bilirubin, albumin, INR, and hemoglobin significantly differed in children with fatal evolution. Function to etiology, PELD, MELD, MELD-Na, and KCC accurately predicted fatal evolution in toxic ALF (25.33 vs. 9.90, p = 0.0032; 37.29 vs. 18.79, p < 0.0001; 34.29 vs. 19.24, p = 0.0002, respectively; with positive predicting value 100%, negative predicting value 88.52%, and accuracy 89.23% for King's College criteria). The Wilson index for predicting mortality had an excellent predictive strength (100% sensibility and specificity), better than the Nazer prognostic index. CONCLUSIONS: Prognostic scores may be used to predict the fatal evolution of ALF in children in correlation with other parameters or criteria. Early estimation of the outcome of ALF is essential, mainly in countries where emergency LT is problematic, as the transfer to a specialized center could be delayed, affecting survival chances.

Clinical features in toxic coma in children.

The purpose was to identify rapidly the etiology of toxic coma in children, to appreciate the severity of the coma, to detect elements of gravity based on associated clinical signs and symptoms and to evaluate the initial treatment. Toxic coma is a medical emergency, especially in a Pediatric Emergency Department, requiring rapid and precise evaluation. The key objectives in the evaluation and management of coma in children are: detecting severity characteristics, depth of coma, specific clinical signs and symptoms, etiological and differential diagnostic and also initializing supportive therapy and specific treatment. This is a retrospective study, where we analyzed all patients diagnosed with coma admitted to the 'Grigore Alexandrescu' Clinical Emergency Hospital for Children over a nine-year period from 2003 to 2011. We focused on toxic coma. A prospective component related to tracking certain signs and symptoms associated with toxic coma to diagnose and initiate appropriate therapy as early as possible was also included. In this nine-year study, 750 comatose patients were included. We found that toxicants represent the main cause of coma in children. There were 445 patients diagnosed with toxic coma, representing 59.3% and 305 cases of non-toxic coma, 40.7% of all coma cases presented in ER. The etiology of toxic coma in children is dominated by alcohol and abuse substances, followed by neurologic medication. Clinical manifestations were more frequent and more severe as the coma degree increases. Associating clinical manifestations in patients with altered neurologic status of toxic cause and toxicants has an important role in practice, because it helps us recognize the frequency of association of coma complications such as: aspiration syndrome, arrhythmias and seizures.

Rare Conduction Abnormality in a Four-year-old Child with Carbamazepine Acute Poisoning.

Background:Cardiac conduction abnormalities are reported after ingestion of a toxic dose of carbamazepine. Case presentation:We describe the case of a four-year-old child with carbamazepine acute poisoning who developed reversible synoatrial block along with neurological toxic signs, despite a serum level of carbamazepine close to the upper limit of the therapeutic range. Discussion:Although carbamazepine-induced sinoatrial block has been reported in the literature even at therapeutic doses in adult patients, our personal research has not identified any record of this cardiac conduction abnormality in acute carbamazepine poisoning at pediatric age. Conclusion:The electrocardiogram is indispensable in the assessment and monitoring of pediatric cases with acute poisoning with carbamazepine.

Peripheral immune cell markers in children with recurrent respiratory infections in the absence of primary immunodeficiency.

The immune system of a child has a degree of immaturity that is maintained until 6-7 years of age. Immaturity may be due to age-related functional disorders in the immune response. A healthy child can contract a series of infections which contribute to the maturation of the immune system during the pre-pubertal period. If repeated infections with prolonged or severe complications occur during childhood, the presence of an immunodeficiency should then be considered. Much more frequent than primary immunodeficiency are recurrent infections (frequently involving the upper respiratory tract), which are less severe and occur under the conditions of an immune system with no apparent major defects. A child can present with 4 to 8 episodes of respiratory infections within a year, during the first 5 years of its life. The average duration of infection is 8 days and up to 2 weeks; if the child presents with 3 episodes of acute infections over a period of 6 months, the respiratory infections are then considered recurrent. The aim of this study was to identify the immunological changes or deviations that cause this clinical syndrome in children. For this purpose, 30 children with recurrent respiratory infections and 10 healthy children were included. Immunoglobulin levels were examined and immunophenotyping was performed. We found that the serum immunoglobulin levels were in the normal range in 70% of the children. On the contrary, our data revealed changes in peripheral cell populations, the most important being the decrease in the T-cluster of differentiation (CD)8+ and total B cell percentages and the increase in the number of memory B cells. The data obtained herein indicated that the decrease in the number of total B cells was mainly due to the decrease in the number of naive IgD+ B cells. On the whole, the findings of this study indicate that recurrent respiratory infections may be associated with an altered cellular immune response. In such situations, the investigation of immunological parameters, such as T and B cell subtypes could complete the clinical diagnosis and guide the treatment strategy, thus increasing the quality of life of patients.

Esophageal Multichannel Intraluminal Impedance and pH Monitoring in the Evaluation of Achalasia and Gastroesophageal Reflux Disease in a Child with Down Syndrome: a Case Report.

We report the case of a rare association between achalasia and Down syndrome in a child presenting with symptoms that suggest a gastroesophageal reflux. Evaluation of the patient with 24-hour multichannel intraluminal impedance and pH recording and upper endoscopy lead to the diagnosis of achalasia. However, the persistence of the symptoms after the concurrent surgical myomectomy and fundoplication has led to repeat pH-impedance monitoring testing and endoscopy, which identified the presence of gastroesophageal reflux disease. We emphasize in this paper the importance of multichannel intraluminal impedance and pH monitoring in detecting esophageal motility disorders.

[Frequency and severity of rotavirus acute gastroenteritis hospitalized in Bucharest, Romania. Results of a case-control study]. / Frecventa si severitatea gastroenteritei acute rotavirale spitalizate în Bucuresti, România. Rezultatele unui studiu case-control.

BACKGROUND: rotavirus gastroenteritis is an emergent condition of morbidity at global level; WHO is currently recommending integration of rotavirus vaccination into the regions and states where rotavirus infection is identified as a public health priority problem. OBJECTIVE: analyzing the frequency and clinical severity of rotavirus gastroenteritis in pediatric inpatients and commenting the programmatic signification of the analysis' results. METHODS: descriptive retrospective study followed by case-control study upon the cohort of patients hospitalized in the year 2008, for acute diarrhoeal disease (ADD) of infectious nature in the biggest university clinic for children from Bucharest municipality. Rotavirus etiology was sustained on the ground of rotavirus antigen's detection, through immune chromatography assay, in the feces of patients with ADD clinical syndrome. The predictor factor for clinical severity was prolonged hospitalization, defined as any duration of hospitalization longer then the value calculated at 75 percentile, in the studied cohort. For the case-control study each case of rotavirus enteritis (Code ICD-10: A08.0) has been matched by age and gender with one control, selected at random from the list of patients with ADD of different etiology than the case. RESULTS: in 2008 in our clinic, a lot of 684 of children was hospitalized for at least 24 hours, for infectious ADD, in which the median age was 8 months and the prevalence of male gender was 49%. In this lot, the prevalence of rotavirus enteritis was 12.7%. Cases of rotavirus enteritis have been admitted all year round, monthly highest prevalence being of 40%. The risk of prolonged hospitalization in patients discharged with the diagnosis of rotavirus enteritis was 2.36 higher (95% Confidence Interval: 1.17-4.78; p < 0.01) than in the same age and gender children hospitalized for ADD of other etiologies. CONCLUSIONS: our study found an annual prevalence of 2.7%, a monthly maximum prevalence of 40% and a risk of prolonged hospitalization of rotavirus enteritis of 2.36 times higher then in ADD cases of other etiologies. In our opinion, these findings encompass objective arguments sustaining that in Bucharest, the rotavirus infection represents a public health problem, with high priority in allocation of health resources, mainly for surveillance and routine immunization.

[Factors influencing the use of systemic antibiotics in hospitalized pediatric patients in Bucharest, Romania]. / Modulatori ai densitatii ratei de consum a agentilor antimicrobieni sistemici la pacientii pediatrici spitalizati în Bucuresti, România.

BACKGROUND: Formulation of effective strategies for prudent usage of antibacterial agents involves knowing of the factors that are modulating the variability of usage rate. OBJECTIVE: analysis of the factors what modulate the usage rate's variability of antimicrobials prescribed to hospitalized children from Bucharest municipality. METHODS: A statistically representative sample (n=895) has been extracted from the cohort of children discharged during October 2008 from the Bucharest's main pediatric university clinic. Demographic, clinic and pharmacological relevant data, captured by reviewing the subjects' medical charts were entered in an Epi Info database. For each enrolled subject the density rate of antimicrobial consumption has been calculated by dividing the pooled number of hospital days in which the subject received at least one dose of each individual antimicrobial agent, by the number of days of hospitalization. For the analysis of antimicrobials usage rate's variability, a rate higher the value calculated at 75 percentile has been defined as overuse. Personal, clinical and prescription characteristics significantly associated, in univariate analysis, with overuse status, were analyzed lately for independent association, by unconditional logistic regression. RESULTS: to the sample's subjects up to 31 individual antimicrobials owning to the J01 group (antimicrobials for systemic use) of the ATC (Anatomical Therapeutic Chemical) classification promoted by World Health Organization were prescribed. In total, in the sample a number of 2607 days of antimicrobial therapy was cumulated, in 60% of these 5 antimicrobials agents were administered: ceftriaxone, gentamicine, cefoperazone, cefazolin and cefuroxime. Antimicrobials overuse was observed in 37% of subjects. By univariate analysis the overuse was significantly associated (p < 0,05) with the following characteristics of the subjects: age under one, with a trip in ICU, diagnosed with LRTI, with a hospitalization longer than 5 days, exposed to more than two antimicrobials agents during the same hospitalization episode and treated with 3rd generation cephalosporins. However, by multivariate analysis, only factors related to antimicrobials prescribing style remained independently associated with overuse status. CONCLUSIONS: In children hospitalized in Bucharest, the antimicrobial agents' consumption is modulated by factors which are specific for this category of patients, factors broadly internationally recognized. Particularly, through multivariate analysis, we found that the factors related with antimicrobials prescription's style explained with the most fidelity the variation of usage density rate in the child hospitalized in Bucharest. The analysis of the modulators of the usage rate's variability is essential for issuing and evaluation of effective interventions focused on antimicrobials' prudent use.

Mortality rate in acute poisoning in a pediatric toxicology department.

INTRODUCTION: Acute poisoning, an important health issue in children can result in some cases in severe evolution and even death. OBJECTIVE: The aim of the study is to analyze cases of death caused by acute poisoning which occurred in a ten-year-period in a Pediatric Toxicology Department in Bucharest. METHODS: For the purpose of the study all medical records of the deceased patients with acute poisoning between 1995-2004 were analyzed with particular focus on the following criteria: etiology, age, social environment, type of intoxication (unintentional or intentional). RESULTS: Between 1995-2004, 46 fatal cases were recorded out of a total 8802 cases of acute poisoning (0.52%). The main two causes of death by acute poisoning were: caustics (16 cases--34.78%) and mushrooms (12 cases--26.08%), followed by carbon monoxide (7 cases 15.11%), pharmaceuticals (5 cases--10.86%), ethanol (2 cases--4.34%), pesticides (2 cases--4.34%), nitrites (1 case--2.17%) and lead tetraethyl (1 case--2.17%). CONCLUSIONS: Although morbidity in acute poisoning is still high, mortality is low, the registered average being 0.52%. The main agents causing death are caustics and mushrooms, and the most affected age group is that between 1 and 5 years of age.
