Organophosphate poisoning from inappropriate topical use of malathion pesticide: A case report

A 43-year-old male with no past medical history presented to our emergency department with vomiting, diarrhea, and abdominal pain of 3 h’ duration. Upon further questioning, he revealed that he had been applying malathion pesticide over his body for the past 3 days for self-diagnosed scabies. He was otherwise afebrile and hemodynamically stable, and the physical examination was unremarkable. The patient was diagnosed with organophosphate poisoning and treated symptomatically due to the lack of worrying cardiorespiratory or neurologic sequelae. He was subsequently admitted to the general ward, where his symptoms abated within 4 h. Serum and red blood cell cholinesterase tests sent on admission returned on day three and were significantly decreased (serum cholinesterase 2131 U/L, reference range 4700–12000 U/L; red blood cell cholinesterase 3365 U/L, reference range 7700–14600 U/L). He was discharged home well and stable on day 5 of admission, with outpatient psychiatric follow-up for likely delusional parasitosis.

Beirut Blast 2020: Cries and Bloodshed at the Busiest Hospital

On August 4, 2020, Beirut experienced a large explosion when 2750 tons of ammonium nitrate detonated in the Beirut port resulting in more than 220 deaths, 76 000 injuries, 300 000 people displaced, and 15 billion dollars loss in property damage. Hôtel-Dieu de France (HDF), one of the largest university hospitals in the capital, has an emergency department that typically accommodates 25 patients. On that night, it received the largest number of injuries and had to accommodate more than 700 casualties within a few hours of the blast. This article describes HDF’s preparedness, emergency response, as well as the distribution of admissions to the emergency department, operation rooms, and the general ward. Surge capacity and the triage system are also detailed.

Cefiderocol for Severe Carbapenem-Resistant A. baumannii Pneumonia: Towards the Comprehension of Its Place in Therapy

Cefiderocol use in A. baumannii pneumonia still represents an important matter of debate. The aim of this study is to describe 13 cases of carbapenem-resistant A. baumannii (CRAB) pneumonia treated with cefiderocol in real-life practice. We retrospectively included patients with CRAB pneumonia hospitalized at Fondazione Policlinico Universitario Agostino Gemelli Hospital treated with cefiderocol either in the general ward or the intensive care unit. A total of 11 patients out of 13 had ventilator-associated pneumonia caused by CRAB, and 12/13 patients had polymicrobial infection. We found a 30-day success rate of 54%. Cefiderocol may have a role when facing severe XDR A. baumannii pneumonia. Future studies are warranted to better define its place in therapy in CRAB infections.

Breakthrough Covid-19 infections during periods of circulating Beta, Delta and Omicron variants of concern, among health care workers in the Sisonke Ad26.COV2.S vaccine trial, South Africa

Background: We report breakthrough infections (BTIs) during periods of circulating Beta, Delta and Omicron variants of concern, among health care workers (HCW) participating in the Sisonke phase 3B Ad26.COV2.S vaccine trial (ClinicalTrials.gov number, NCT04838795). Data were gathered between 17 February and 15 December 2021. Duration of each period in this study was 89 days for Beta, 180 days or Delta and 30 days for Omicron. Results: A total of 40 538 BTIs were observed, with 609 during Beta, 22 279 during Delta and 17 650 during Omicron. By 15 December, daily infections during Omicron were three times that seen during the peak observed during Delta. However, unlike the Delta period, with Omicron there was a clear and early de-coupling of hospitalisation from cases as a percentage of the Delta peak curves. Omicron significantly infected a greater proportion of HCW in the 18-30 year age-group, compared with the 55+ age group. There were 1 914 BTI-related hospitalisations - 77, 1 429 and 408 in the Beta (89 days), Delta (180 days) and Omicron (30 days) periods, respectively. During Omicron, 91% hospitalized HCWs required general ward care, 6% high care and 3% intensive care, compared with 89% general ward care, 4% high care and 7% intensive care, during Delta and 78% general care, 7% high care and 16% intensive care during Beta (p<0.001). During Beta and Beta 43% of hospitalized HCW needed supplementary oxygen and 7-8% needed ventilation, compared with 16% and 0.2% respectively during the Omicron period (p<0.001). Median length of hospitalization was significantly lower with Omicron compared with Beta and Delta (3 days compared with 5-6 days, p<0.001). Conclusions: We illustrate more BTIs but reassuringly less severe Covid-19 with Omicron. Re-infections and Omicron-driven primary infections were likely driven by high population SARS-CoV-2 seroprevalence, waning vaccine effectiveness over time, increased Omicron infectivity, Omicron immune evasion or a combination of these and need further investigation. Follow-up of this cohort will continue and reports will be updated, as time and infections accrue.

Management of self-inflicted oral organophosphate poisoning in adolescence - a case report

Organophosphate (OP) poisoning is more common in developing countries such as India. Here, we report a case of self-inflicted oral OP poisoning (monocrotophos) by an adolescent male patient who presented to the emergency department of a tertiary care hospital with tachycardia and frothing without seizure episode (non-linear presentation in OP poisoning). Based on the evidence of consumption of OP compound, the management of the patient went as planned and guarded with i.v. administration of pralidoxime and atropine. Gastric lavage was done soon after the patient came to the hospital and was admitted to the Intensive care unit for 5 days and in the general ward for the next 24 h. The patient was discharged from the hospital in a hemodynamically stable state after 6 days of hospital stay by managing the cardiac, muscarinic, and nervous system events as detailed in this case report.
