RESUMO
Background: A patient with a retained intraocular metallic foreign body post?trauma was taken up for vitrectomy and intraocular foreign body removal. Unfortunately, the intraocular magnet was not available at the moment on the table! How a little bit of creativity and innovative thought helped us tide over this crisis is the content of this video. Purpose: To demonstrate magnetization of a metallic surgical instrument for temporary use in the event of unavailability of the intraocular magnet for intraocular foreign body removal. Synopsis: A ferromagnetic substance can be magnetized temporarily using an existing magnet. We obtained a general?purpose magnet and wrapped it in sterile plastic, using which we magnetized normal intraocular forceps and a Micro Vitreo Retinal (MVR) blade by giving about 20–30 strokes over the magnet in a single direction. This aligned the magnetic domains in the metal in a parallel fashion. These Do It Yourself (DIY)? magnetic instruments were then effectively utilized to remove the metallic intraocular foreign body. Highlights: The video showcases effectively harnessing the available resources and tiding over the dearth of a necessary instrument, with the right use of an innovative idea and some creativity!.
RESUMO
Objective: To study the adverse events following immunization (AEFI) with Covishield, a coronavirus disease– 2019 (COVID-19) vaccine. Materials and Methods: A prospective observational study was conducted among 422 Covishield vaccinees based on the inclusion and exclusion criteria after the institutional ethics committee approval. They were followed up at the end of 1 and 2 weeks following the first dose of Covishield vaccine, and the details of adverse events were collected. AEFIs were classified using system organ classification, World Health Organization-Uppsala Monitoring Center (WHO-UMC) causality assessment, AEFI causality assessment, and Modified Hartwig Severity Scale. Various classifications of AEFI were analyzed using descriptive statistics. ANOVA and independent t-test were used for age group and gender comparison of the duration and number of AEFI, respectively. Results: Around 625 AEFIs were reported by 422 vaccinees. Majority of the vaccinees (62.8%) developed adverse events on the day of vaccination. The mean duration of AEFI was 2.52 ± 0.871 days. On WHO-UMC causality assessment, 98.08% were found to be probable, 1.12% possible, and 0.8% unclassifiable. AEFI causality assessment revealed 98.88% vaccine product-related reactions and 1.12% anxiety-related reactions. Regarding the severity, 83.52% of AEFIs were mild and 16.32% were moderate. On comparison of mean duration of AEFI (P = 0.298) and mean number of AEFI (P = 0.569) between different age groups, no statistical significance was observed. Conclusion: The majority of AEFIs reported in this study were mild to moderate in severity for a short duration. The protection offered against the deadly disease and its complication potentially outweighs the mild AEFIs or inconvenience caused by them. Hence, covid-19 vaccination is an important tool to break the pandemic chain.
RESUMO
We present the case of a 16-year-old female patient who presented with dyspnoea, cough and noisy breathing that progressed further in hospital with the development of stridor and severe respiratory compromise requiring mechanical ventilatory support. Investigations were consistent with a diagnosis of endotracheal tuberculosis with tracheal and bronchial stenosis. Despite adequate anti-tuberculous therapy and ventilation the patient had high airway pressures, low tidal volumes and hypercapnia, which prevented weaning from mechanical ventilation. Balloon dilatation and stenting of the 4.5cm long, 2.3mm diameter stenotic tracheal segment was performed under radiological guidance. The patient was weaned successfully from the ventilator post-procedure. This report illustrates the successful management of an uncommon presentation of a common disease with modern endoscopic therapy.
