Accidental iron poisoning in children - Experience from a teaching institution.

Background: Acute iron toxicity is fatal in children resulting from an accidental overdose of maternal iron tablets at home. There is scanty literature on children looking at the profile and outcome. We report a case series of five children presenting after accidental ingestion of iron tablets. Two presented with fulminant hepatic failure at 48 h, and despite supportive management and plasmapheresis in one child, both succumbed to illness. Materials and Methods: This retrospective study was conducted in the pediatric intensive care unit (PICU) of a teaching institution in South India between January 2009 and December 2019. All children with accidental iron poisoning were included in the analysis. Results: During the study period, five children presented to our PICU after accidental iron tablet ingestion. The mean age was 25.8 months [standard deviation (SD): 13.9]. All the children had consumed iron tablets from their pregnant mothers. Two children presenting with liver failure succumbed to illness. Treatment included a standard protocol of gastric lavage and desferrioxamine. Most of them (3/5) received whole bowel irrigation. We did plasmapheresis in one child who presented with fulminant hepatic failure. The majority were discharged alive (3/5). The presence of coagulopathy, acute liver failure, and delayed presentation were associated with high mortality. Conclusion: Accidental iron poisoning is prevalent in children and associated with significant mortality. Parents and caretakers must be counseled by primary care physicians and made aware of the safe storage of iron tablets.

Improving Transplant-free Survival With Low-volume Plasma Exchange to Treat Children With Rodenticide Induced Hepatotoxicity.

Background: In a prior report, no patient with rodenticidal hepatotoxicity who met Kochi criteria (MELD score ≥36 or baseline INR ≥6 with hepatic encephalopathy) (PMID: 26310868) for urgent liver transplantation survived with medical management alone. Plasma exchange (PLEX) may improve survival in these patients. Objectives: We describe our experience with low-volume PLEX (PLEX-LV) in treating rodenticide ingestion induced hepatotoxicity in children. Methods: From prospectively collected database of rodenticidal hepatotoxicity patients managed as in-patient with department of Hepatology from December 2017 to August 2021, we retrospectively studied outcomes in children (≤18 years). Hepatotoxicity was categorized as acute liver injury (ALI, coagulopathy alone) or acute liver failure (ALF, coagulopathy and encephalopathy). Kochi criteria was used to assess need for urgent liver transplantation. The primary study outcome was one-month survival. Results: Of the 110 rodenticidal hepatotoxicity patients, 32 children (females: 56%; age: 16 [4.7-18] years; median, range) constituted the study patients. The study patients presented 4 (1-8) days after poison consumption (impulsive suicidal intent:31, accidental:1). Twenty children (62%) had ALI [MELD: 18 (8-36)] and 12 (38%) had ALF [MELD: 37 (24-45)].All children received standard medical care, including N-acetyl cysteine; ALF patients also received anti-cerebral edema measures. None of the patient families opted for liver transplantation. Seventeen children (ALI: 6, ALF: 11) were treated with PLEX-LV (3 [1-5] sessions, volume of plasma exchanged per session: 26 [13-38] ml/kg body weight) and peri-procedure low dose prednisolone.At 1 month, 28 of the 32 children (87.5%) were alive (4 ALF patients died). Of 10 children who met Kochi listing criteria for urgent liver transplantation, two children were ineligible for PLEX-LV (due to hemodynamic instability) and of the remaining 8 children treated by PLEX-LV, 6 (75%) survived. Conclusions: PLEX-LV shows promise as an effective non-liver transplant treatment in children with rodenticidal hepatotoxicity.

Changing trends in the profile of rodenticide poisoning.

Background: Deliberate self-poisoning (DSP) is one of the leading causes of mortality and morbidity, with rodenticides being common compounds used by many victims. However, comprehensive data regarding the spectrum and outcome of rodenticide poisoning is scant. Method: This retrospective study was conducted in the Emergency Department (ED) of a large tertiary care hospital in South India between January 2017 and December 2018. All patients with deliberate consumption of rodenticides were included in the analysis. Results: During the study period, 1802 patients presented with DSP, among which 145 (8%) consumed rodenticide compounds. The mean (SD) age was 27.9 (10.7) years. Young adults (16-30 years) comprised 73% (106/145) of the study population. The majority (87%) were triaged as priority 2, while 10% were triaged as priority 1. Common rodenticide compounds consumed were yellow phosphorous (57%: 82/145), coumarins (12%: 17/145), zinc phosphide (19%: 27/145), and aluminum phosphide (1%: 1/145). A significant proportion of patients (18.6%) were under the influence of alcohol. Among the 73 males, 25 (34.2%) gave a history of co-consumption of alcohol. There was a history of previous DSP attempts in 6%. The majority (68%) of the patients were discharged alive from the hospital, and the in-hospital mortality rate was 9%. Age >30 years (adjusted OR: 2.2; 95% CI: 1.00-5.05; p value: 0.04) was an independent predictor of poor outcome. Conclusion: Rodenticide compound consumption for DSP is prevalent in young adults and is associated with significant mortality, especially with yellow phosphorous poisoning. The current trend in our country of the increasing use of highly fatal phosphorous compounds over the innocuous coumarin derivatives is a cause of grave concern.

Risk Factors for Candida Infection among Children Admitted to a Pediatric Intensive Care Unit in a Tertiary Care Centre in Southern India.

Background: To describe the clinical profile, risk factors, and outcomes that are associated with candida infection among critically ill children. Patients and methods: A retrospective case-control study wherein 109 children admitted to the pediatric intensive care unit (PICU) in the years between 2015 and 2017 with the growth of candida from blood, urine, endotracheal (ET) aspirate, and pus swabs were included and compared to 97 age and sex-matched controls chosen from the same time period. Results: Of the 124 candida isolates from 109 children, 37% were from blood, 24% from urine, and 14% in pus; 40% of the isolates were from ET aspirate. Candida non-albicans types (70%) predominated with Candida tropicalis causing 50% of the infections. Risk factors for candida infection were neutropenia [OR 20.01, 95% CI (0.94-422.32)], mechanical ventilation [OR 5.97, 95% CI (2.44-14.62)], peritoneal dialysis [OR 5.81, 95% CI (1.27-26.50)], institution of amino acids [OR 5.41, 95% CI (0.85-34.13)], presence of central venous catheter [OR 3.83, 95% CI (1.59-9.19)], antibiotic use >5 days [OR 3.58, 95% CI (1.38-9.29)]. Candida Cases (95.4%) had a septic shock with acute kidney injury in 34% and had significantly lower survival than controls [72 (66%) of 109 vs. 74 (80%) of 92] (p = 0.023). Conclusions: The rate of candida infection in our PICU was 4.2% of PICU admissions. The most common species was C. tropicalis. The independent risk factors for candida infection were neutropenia, antibiotic duration >5 days, peritoneal dialysis, amino acid administration, mechanical ventilation, and presence of a central venous catheter (CVC).

Scrub Typhus: A Spatial and Temporal Analysis from South India.

Scrub typhus is a zoonotic rickettsial disease caused by the bacterium Orientia tsutsugamushi. The non-specificity of presentation, low index of suspicion and the poor availability of diagnostic tests often lead to delayed diagnosis and significant morbidity and mortality. Temperature, humidity, rainfall and Normalized Difference Vegetation Index (NDVI) on the spatio-temporal clustering of scrub typhus cases in children in three contiguous administrative districts in South India over 5 years were studied. A total of 419 children were diagnosed with scrub typhus during the study period. A surge of children with scrub typhus was noted when the NVDI ranged between 0.6 and 0.8 µm. Temperature, humidity and rainfall had a major role in the incidence of scrub typhus.

Spectrum of COVID-19 Disease in Children: A Retrospective Analysis Comparing Wave 1 and Wave 2 from a Tertiary Hospital in South India.

OBJECTIVE: To describe COVID-19 in children and the differences between the two waves. METHODS: The electronic medical records of children younger than 16 y of age with laboratory-confirmed COVID-19 infection between June 1st 2020 and May 31st 2021 at Christian Medical College, Vellore were retrospectively reviewed. Demographic, clinical, and laboratory data were collected on a predesigned case record form and analyzed. RESULTS: A total of 988 children were diagnosed with confirmed COVID-19 during the study period. Of these, there were 585 children diagnosed during the 1st wave (June 2020-Feb 2021) and 403 children during the 2nd wave (March 2021-May 2021). It was found that loose stools and rash were significantly more frequent during the 1st wave and fever, cough, coryza, heart rate and temperature were significantly more during the 2nd wave. There was no significant difference between the two groups in terms of requirement of oxygen therapy, need for ICU admission, duration of ICU stay or hospital stay, or severity of illness. Mortality was significantly higher during the 2nd wave (0.3% vs. 2%). CONCLUSION: The COVID-19 pandemic among children during the 1st and 2nd waves were similar in severity, though there was a higher mortality during the 2nd wave.

Clinical Spectrum of Children With Multisystem Inflammatory Syndrome Associated With SARS-CoV-2 Infection.

OBJECTIVES: To compare the clinical profile, treatment, and outcomes of PCR-positive and PCR-negative antibody-positive critically ill children with multisystem inflammatory syndrome (MIS-C). METHODS: This retrospective observational study was done at a tertiary care coronavirus disease 19 (COVID-19) pediatric intensive care unit in India. The baseline characteristics, clinical profile, treatment, and outcomes in seventeen critically ill children diagnosed with MIS-C were analyzed from 1 July to 31 October, 2020. RESULTS: Sixteen out of 17 children presented with hypotensive shock and respiratory distress. Mean (SD) age of PCR-negative antibody-positive and PCR-positive children was 11 (4.4) and 5 (3.7) years, respectively (P=0.007). The former group had significantly higher mean (SD) D-dimer levels [16,651 (14859) ng/mL vs 3082 (2591) ng/mL; P=0.02]. All received intensive care management and steroid therapy; 7 children received intravenous immunoglobulin. 14 children survived and 3 died. CONCLUSIONS: The outcome of children with MIS-C was good if recognized early and received intensive care.

Paediatric trauma aetiology, severity and outcome.

BACKGROUND: Paediatric injuries are a major cause of mortality and disability worldwide and account for a significant burden on countries like India with limited resources. There are very few studies from developing nations describing the outcome of paediatric trauma. METHODOLOGY: This retrospective study was done to assess the pattern and outcome of unintentional paediatric trauma in the paediatric population. The patients were categorised into four age groups of <1 year, 1-5 years, 6-10 years and 11-15 years. The data were compared regarding the mode of trauma, new injury severity score (NISS), type of injury and place of injury among different age groups. RESULTS: A total of 1587 paediatric patients below 15 years of age presenting in the Emergency Department of CMC, Vellore were studied over a period of 1 year. Two-thirds were boys (1039: 66.6%). Fall on level ground (28.2%) and road traffic accidents (RTA) (26.5%) were the two most common modes of injury. A gradual change in the place of incident from home to the road with advancing age was noticed. The upper limb (30.8%) and the face (26.2%) were the most common parts of the body to be injured. One-third (35.8%) of the sustained serious injuries was a fracture or a dislocation. RTA (OR: 1.56; 95%CI: 1.08-2.26) and age ≥5 years (OR: 1.17; 95%CI: 1.08-1.26) were found to be independent predictors of severe injury (NISS >8). Only 15% required hospital admission. CONCLUSION: Fall on level ground and RTAs are the most common modes of injury in the paediatric population. The place of injury shows a gradual change from the confines of home to the open dangerous roads and playgrounds with increasing age with RTA and age ≥5 years being independent predictors of severe injury.

Profile and outcome of patients presenting with agrochemical poisoning to the emergency department.

BACKGROUND: Deliberate self-harm (DSH) is one of the leading causes of mortality and morbidity in India. Agrochemicals are the most commonly used compounds for DSH. The spectrum of Agrochemicals in use varies from region to region and time period with newer compound being regularly introduced into the market. METHODOLOGY: This retrospective cohort study included patients presenting with agrochemical poisoning to the ED during January 2017 to December 2018. Patient data was retrieved form the ED triage registry software and clinical workstation, following which their hospital outcome was determined. RESULTS: During the study period, 1802 patients presented with DSH among which Agrochemical poisoning comprised 33.5% (604/1802). The mean age was 31 years and incidence of agrochemical poisoning was found to be higher in young adults (16-30 years-55.8%). The prevalence was more common in males (62.4%). The common agrochemical compounds consumed were insecticides (91%), herbicides (4.3%), fungicides (1.5%), fertilizer (1.5%), and plant growth regulators (1.5%). Majority (80.96%) of the patients were discharged alive from the hospital, 17% left against medical advice due to bad prognosis and 12 patients (2%) died in the hospital. CONCLUSION: Insecticides (mainly Organophosphates) are the most common agrochemicals used for DSH. Their management is better understood leading to better outcomes compared to other chemicals. The proportion of agrochemical use in DSH has reduced over the last decade. Imidacloprid (Insecticide) and Plant growth regulators are the new compounds for which appropriate management is not yet established and more research is needed.

Perinatal Risk Factors for Neonatal Early-onset Group B Streptococcal Sepsis after Initiation of Risk-based Maternal Intrapartum Antibiotic Prophylaxis-A Case Control Study.

OBJECTIVES: To identify the perinatal risk factors for early-onset Group B Streptococcus (EOGBS) sepsis in neonates after inception of a risk-based maternal intrapartum antibiotic prophylaxis strategy in 2004. DESIGN: Case control study. METHODS: All newborn with early onset GBS sepsis (born between 2004 and 2013) were deemed to be "cases" and controls were selected in a 1:4 ratio. RESULTS: More than three per vaginal (PV) examinations [odds ratio (OR) 8.57, 95% confidence interval (CI) 3.10-23.6] was a significant risk factors. Peripartum fever (OR 3.54, 95% CI 1.3-9.67), urinary tract infection (OR 2.88, 95% CI 1.08-7.63), meconium-stained amniotic fluid (MSAF) (OR 2.52, 95% CI 1.18-5.37) and caesarean section (OR 1.99, 95% CI 1.16-3.43) were also found to be associated with EOGBS sepsis. CONCLUSION: Multiple vaginal examinations are the strongest risk factors for peripartum Group B Streptococcal (GBS) sepsis. The association of MSAF and caesarean section indicates that foetal distress is an early symptom of perinatal GBS infection.

A novel mutation c.1048A>T at codon 350(Lys>Stop) in PROC gene causing neonatal purpura fulminans.

Purpura fulminans in the neonatal period due to severe congenital protein C deficiency (protein C activity <1 IU/dl) is a rare autosomal recessive disorder. If untreated, it is fatal. Early identification of such patients may be lifesaving. Acquired deficiency of protein C caused by increased consumption as overt disseminated intravascular coagulation (DIC) and severe infection creates a diagnostic dilemma. Mutation analysis plays a critical role in confirming the diagnosis of the disease and offering prenatal diagnosis. In this report, we describe a newborn who presented with purpura fulminans and DIC, molecular analysis showed a novel c.1048A>T transversion in a homozygous state at codon 350 (Lys>Stop) of protein C (PROC) gene. Prenatal diagnosis in subsequent pregnancy was done which revealed the affected fetus had the same mutation in homozygous form.

Hair dye poisoning in a paediatric patient.

Hair dye ingestion with suicidal intention has increased among rural Indian population and is associated with significant mortality. We report a teenager who presented with cervicofacial edema, respiratory distress, rhabdomyolysis, and myocarditis after ingesting the hair dye Super Vasmol 33. Early and supportive treatment can prevent morbidity and mortality.
