Background: Pyrethroid insecticides are commonly used insecticides. This study was undertaken to characterize the clinical profile and outcome of deliberate self-harm (DSH) with type 1 and type 2 pyrethroids and identify factors associated with need for hospitalization.

Methods: This retrospective study was conducted in a tertiary care hospital in South India to study the clinical features, treatment, and outcome of patients with pyrethroid poisoning due to DSH.

EASIER trial (Erector-spinAe analgeSia for hepatopancreaticobiliary pain In the Emergency Room): a single-centre open-label cohort-based randomised controlled trial analysing the efficacy of the ultrasound-guided erector-spinae plane block compared with intravenous morphine in the treatment of acute hepatopancreaticobiliary pain in the emergency department.

Background: Ultrasound-guided (USG) erector-spinae plane block (ESPB) may be better than intravenous opioids in treating acute hepatopancreaticobiliary (HPB) pain in the ED.

Methods: This open-label randomised controlled trial was conducted in the ED of a tertiary-care hospital between March and August 2023. All adult patients with severe HPB pain were recruited during times that a primary investigator was present.

Background: During the COVID-19 pandemic, many patients presented to the emergency department (ED) with features of Influenza-like illnesses (ILI) and with other atypical presentations. This study was done to determine the etiology, co-infections, and clinical profile of patients with ILI.

Methods: This prospective observational study included all patients presenting to the ED with fever and/or cough, breathing difficulty, sore throat, myalgia, gastrointestinal complaints (abdominal pain/vomiting/diarrhea), loss of taste and altered sensorium or asymptomatic patients who resided in or travelled from containment zones, or those who had contact with COVID-19 positive patients during the first wave of the pandemic between April and August 2020.

Performance of Aerosol Boxes for Endotracheal Intubation during the COVID-19 Pandemic with Systematic Review.

Introduction: In the backdrop of the COVID-19 pandemic, endotracheal intubation using an aerosol box (AB) became the norm in the emergency department (ED) and the intensive care unit. We compared two models of AB with different dimensions to compare and identify a device that helps in reducing viral exposure without compromising successful airway management.

Methods: We conducted this prospective observational study for 7 months (October 20-April 21) on 143 patients presenting with an acute airway compromise to the ED.

Profile and outcome of COVID-19 patients treated at a secondary hospital in Central India during the second wave of the pandemic.

Background: The second wave of the coronavirus disease 2019 (COVID-19) pandemic resulted in a significant rise in the number of infections and deaths as compared to the first wave. The published literature till now is limited to tertiary hospitals. We did this study to describe the demographic characteristics and outcomes of patients admitted to a secondary care hospital in central India during the second wave of the pandemic.

Role of Neutrophil Gelatinase-associated Lipocalin (NGAL) and Other Clinical Parameters as Predictors of Bacterial Sepsis in Patients Presenting to the Emergency Department with Fever.

Background: Bacterial sepsis is associated with significant morbidity and mortality. However, to date, there is no single test that predicts sepsis with reproducible results. We proposed that using a combination of clinical and laboratory parameters and a novel biomarker, plasma neutrophil gelatinase-associated lipocalin (NGAL) may aid in early diagnosis.

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.

Intravenous Doxycycline, Azithromycin, or Both for Severe Scrub Typhus.

Background: The appropriate antibiotic treatment for severe scrub typhus, a neglected but widespread reemerging zoonotic infection, is unclear.

Methods: In this multicenter, double-blind, randomized, controlled trial, we compared the efficacy of intravenous doxycycline, azithromycin, or a combination of both in treating severe scrub typhus. Patients who were 15 years of age or older with severe scrub typhus with at least one organ involvement were enrolled.

Immunogenicity and safety of homologous and heterologous booster vaccination of ChAdOx1 nCoV-19 (COVISHIELD™) and BBV152 (COVAXIN®): a non-inferiority phase 4, participant and observer-blinded, randomised study.

Background: Primary SARS-CoV-2 vaccination has been shown to wane with time and provide lower protection from disease with new viral variants, prompting the WHO to recommend the administration of booster doses. We determined the safety and immunogenicity of homologous or heterologous boosters with ChAdOx1 nCoV-19 (COVISHIELD™) or BBV152 (COVAXIN®), the two vaccines used widely for primary immunization in India, in participants who had already received two primary doses of these vaccines.

Methods: Participants primed with two doses each of COVISHIELD™ or COVAXIN® 12-36 weeks previously, were randomised to receive either COVISHIELD™ or COVAXIN® booster in a 1:1 ratio.

Purpura Fulminans and Spotted Fever: A Case Series from South India.

Purpura fulminans (PF) is associated with acute infections such as meningococcal, staphylococcal, streptococcal, and rickettsial infections. However, there are only a few reports of association of PF with rickettsial fever from India. In this case series of seven adults with PF, four were definitive cases of spotted fever as the ompA real-time polymerase chain reaction was positive.

Benthic foraminifera as an environmental proxy for pollutants along the coast of Chennai, India.

Benthic foraminifera are increasingly used as an indicator of environmental disturbance. Their sensitivities to pollutants can be reflected by changes in assemblage, which can provide useful information about ecosystem health. This study aimed to investigate the impact of organic and inorganic pollutants on the benthic ecology of the Chennai coast, with a focus on the 2017 oil spill caused by the collision of two ships.

Code blue: Predictors of survival.
