SMART KNIFE SNIFFS OUT CANCER CELLS THE TRIVIA Breast cancer is the commonest cancer in women, with the fifth highest THEATRE mortality rates worldwide. Breast conserving surgery (BCS) is the most commonly performed surgical technique for the treatment of women with early-stage breast cancer. Over a fifth of patients undergoing BCS require re- operation for inadequate margins. Positive resection margin following BCS UNBELIEVABLE STORY BEHIND more than doubles the chance of ipsilateral breast tumor regional recurrence THE INVENTION OF CARDIAC (IBTR). CATHETERIZATION Re-operative intervention is associated with greater patient anxiety, impaired cosmesis, a higher incidence of post-operative wound complications, delay Imagine a cardiologist considering receipt of adjuvant therapies and increases healthcare costs. Intraoperative ureteric catheter to perform cardiac margin assessment (IMA) techniques like frozen section and cytology, catheterization. Unbelievable, specimen (SR) and intraoperative ultrasound (IOUS) aim to provide impossible! However, it took all the courage and determination of a the surgeon with actionable information about margin status in the midst of young surgery resident to try this to the index procedure to reduce the need for re-operation. However, the achieve one of clinical ’s limitations of pathological techniques, including slow turnaround times, greatest advances. The name of that manpower requirements, and the potential for false positive interpretation, resident was and have limited international adoption & compared to pathological techniques he did it in 1929. Specimen radiology and IOUS have inferior accuracy.

Rapid evaporative ionization mass spectrometry (REIMS) is an ambient ionization technique that utilizes the aerosol by-product of electrosurgical Werner Forssmann saw a picture in a book showing how a tube was (Bovie) tools. The electrosurgical process of cutting or coagulating tissue inserted into the of a horse causes heat to dissipate inside the tissue resulting in release of cellular content through a . A at the to the gas phase. Aspiration of the aerosol allows for rapid mass spectrometric other end of the tube showed chemical analysis and computational algorithms can “learn” (cf. ‘machine- changes in pressure. He was learning’) to recognize the chemical differences between tissue types. The convinced that a similar experiment technology can identify tissue characteristics within a few seconds of could be carried out on people and electrosurgical activation. was determined to prove his hypothesis that Cardiac The REIMS system or intelligent knife (), capable of providing intuitive Catheterization wasn’t as lethal as feedback on real-time tissue characterization at the point of , offers everyone thought it was. a potential solution.

She laid down on a UNEXPECTED PRESENTATION OF COVID bed in the supply room — and then A 42-year-old male presented with decreased vision in both eyes for six days. He had a Forssmann surprised her, he tied her history of fever with sore throat 12 days ago and was diagnosed positive for COVID-19, to it. Forssmann pulled out a treated in hospital for the next 10 days with supportive therapy, and was discharged Catheter and inserted the tube into after RT-PCR tested negative. On ocular examination, best-corrected visual acuity was his own arm. With the tube still in his RE: 6/18 and LE: 6/24.

Fundus fluorescein (FFA) revealed no leakage or any hyper fluorescence in both eyes. Hence, diagnosis of maculopathy secondary to COVID-19 infection was made. Systemic workups for vasculitis as well as ischemic causes of maculopathy were unremarkable. In view of a probable immune-mediated etiology and corticosteroid being the mainstay of the treatment, the patient was prescribed oral steroids on weekly tapering dosages. The best-corrected visual acuity improved to RE: 6/9 and LE: 6/12 at four weeks.

Despite the emergence of new data and an invasive study of cardiac anatomy ongoing increase in understanding of the disease, there are several ocular features and and function. related complications of COVID-19 disease that remain unknown. Clinicians need to be vigilant for the presence of such potential ocular manifestations as the likely presentation of COVID-19 disease.
