    Posle kratkog uvoda u istorijat naĆĄeg znanja o patogenezi električne katarakte, autori prikazuju jedan slučaj pojave ove katarakte kod radnika, koji je bio povređen strujom visoke voltaĆŸe (35.000 V). Zamućenje sočiva je usledilo posle ĆĄest meseci i to intenzivnije na strani tela, koja je bila dalje od izvora struje. Bolesnik je operisan i vid je integralne povraćen. Preporučene su neke profilaktične mere za zaĆĄtitu ovih radnika. Autori zavrĆĄavaju članak jednom hipotezom, koja treba da objasni »latentni period«, poznat kod ove vrste katarakte, teorijom auto-agresije na bazi sudara auto-antitela, koji bi bili odgovorni za brzinu, stepen i intenzitet nastale katarakte.After a short introduction into the main characteristics of electric cataract, the authors present a case of electric cataract in a worker injured by the high voltage current (35.000 V). After a »Iatent period« lasting 6 months, the disease appeared in both lenses, but more intensely on the lense of the left eye which was further away from the passage of the electric current. In their case the electric arc did not pass through the head as was usual in all the cases described so far, but through the raised hand and the chest. What the authors particularly point out are the changes at the base of both eyes, in the region of macula, which in their clinical picture resemble the changes observed in those who happen to look at the sun in eclipse with unprotected eyes. On the basis of this finding the authors are inclined to think that these changes are more likely to be caused by the intense light in the moment of short circuit than by electric energy. After the operation of the left eye and with a corrective glass, the normal visual acuity has returned to the patient. The changes on the right eye have remained stationary. The authors briefly discuss certain prophilactic measures to be introduced in electric industry, as well as the rehabilitation of workers suffering from electric cataract. A hypothesis on the mechanism of the disease is also given

    AimThe SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery.MethodsThis was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin.ResultsOverall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P ConclusionOne in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease
