A retrospective analysis of ingestion of caustic substances by children. Ten-year statistics in Galicia
We reviewed the case histories of 743 children seen at our hospital from 1981 to 1990 for suspected ingestion of caustic substances. Mean patient age was 27 months; 85% of patients were less than 3 years old. The male-to-female ratio was about 2:1. About 53% of patients were from urban environments. All ingestions appear to have been accidental. Of the 743 children, 20% presented oesophageal burns (11.8% first-degree, 3.1% second-degree and 2.7% third-degree). Alkaline products were ingested about 11 times more frequently than acid products. The substance ingested was bleach in 73% of cases. The most dangerous substances were dishwasher liquids/powders (59% of ingestions led to oesophageal burn), caustic soda (55%) and drain cleaners (55%). The caustic product was not in its original container in 75% of cases. Most accidents (58%) took place in the home. We did not detect any reliable predictive relationship between the presence of symptoms and signs and of oesophageal burns. Of the 743 patients, 5% developed oesophageal stricture and 3% required oesophageal dilatation. Conclusion: The incidence of accidents caused by the ingestion of caustic substances can only be reduced by broad-based preventive strategies, including enforcement of safe manufacturing practices and public education programmes. Most importantly, the containers for caustic household products should be cheap, small and childproof.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Measurement of colonic transit time in children
Transit times through the whole colon and its segments were measured in 10 healthy children and 14 children suffering constipation secondary to myelomenin-gocele. The subjects ingested radio-opaque markers on three successive days, and on the fourth a plain abdominal roentgenogram was taken using fast film. In the healthy children, total colonic transit time (mean ± SD) was 37.8 ± 6.2 h, with segmental times of 10.8 ± 3.5 h for the right colon, 12.2 ± 2.7 h for the left, and 14.7 ± 2.1 h for the rectosigmoid; upper normal limits of 17.8 h for the right colon, 17.6 h for the left, 19.1 h for the rectosigmoid, and 50.2 h for the total colonic transit time were established. In the constipated children, the total transit time was 59.9 ± 5.4 h, with segmental times of 15.9 ± 2.3 h for the right colon, 18.9 ± 2.3 h for the left, and 25.0 ± 2.6 h for the rectosigmoid. The technique described is simple, is easy to use in clinical practice, and involves a lower radiation dose than other methods. It may prove useful for measurement of colonic transit time in suitable patients. © 1991 Raven Press, Ltd. New York.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
What is the infection risk of oesophageal dilatations?
Oesophageal dilatation is the most widely used treatment option for the management of oesophageal strictures. Complications include bleeding, a slight increase in body temperature, thoracic or abdominal pain, oesophageal perforation, brain abscess and bacteraemia. We performed a prospective study to evaluate the frequency of postdilatation bacteraemia in nine patients subjected to a total of 50 dilatations. Bacteraemia was detected in 36 cases (72%). In all but three cases, however, it was transient and not associated with fever or other clinical complications. The organisms most commonly responsible (64%) were alpha-haemolytic streptococci (Streptococcus viridans), probably originating as contaminants from the oropharynx and oesophagus and introduced into the bloodstream during dilatation. Despite the relatively low incidence of bacteraemia-related postdilatation complications, the potential severity of such complications argues for the use of antibiotic prophylaxis as a routine measure prior to oesophageal dilatation. Conclusion. Oesophageal dilatation is associated with a high incidence of bacteraemia. The organisms most commonly responsible were alpha-haemolytic streptococci. We recommend the use of antibiotic prophylaxis as a routine measure prior to oesophageal dilatation.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Effects of pre-operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study an international prospective cohort study
We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05–1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4–7 days or ≥ 8 days of 1.25 (1.04–1.48), p = 0.015 and 1.31 (1.11–1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.
