Abstract

Background. Air pollution is the result of household waste responsible for 3.8 million death and 7.7% of all mortality over the world. One air pollutant which tends to increase year by year is carbon monoxide (CO). CO is produced as the result of the imperfect combustion of machines and the combustion of charcoal. The purpose of this study is to assess the correlation between CO level in exhaled air and pulmonary function on grill street-vendors in Medan city. Method: This study is an observational analytic with a cross-sectional approach. The subjects were grill in Medan city who fulfilled certain inclusion and exclusion criteria with the consecutive sampling method. This study data is primary data which is collected using a questionnaire, smokerlyzer, and spirometry. Result: The subjects of this study are 25 grill street-vendors. Most subjects in this study have red (40%) and green (32%) zone in CO exhaled test and as in pulmonary function test, restrictive (56%) and mixed-type (40%) are the most. The Spearman correlation result between CO level in exhaled air and pulmonary function  FEV1 and FVC are not significant (p=0.068 and p=0.251). Conclusion: There is no significant correlation between CO levels in exhaled air and pulmonary function

Abstract

Highlights: 1. An insight on how precordial catch syndrome could be a potential research base for further research because of its rarity. - Background: This syndrome is rarely discussed in the differential diagnosis of chest pain, as it deserves wider recognition. Pediatricians report that PCS accounts for 80% to 90% of chest discomfort in the absence of trauma, primarily in adolescent and young adults. The classic pain history can help identify precordial catch syndrome, often eliminating the need for further testing or referrals. The diagnosis of precordial catch can be challenging due to various inconclusive workups. However, once diagnosed, this condition can be managed conservatively. Objective: This review sought to describe the distinctive features of the syndrome and its management strategy. Method: Descriptive review method was used in this study to provide a comprehensive overview for this study. Results: The pain is sudden in onset, is severe, and is localized above the cardiac apex (fifth intercostal space within the left midclavicular line). General testing is required to exclude various conditions., but several tests like ECG and chest x-ray can be done to rule out other causes of chest pain. Though in pediatric considerations, classic pain history can help identify PCS, often eliminating the need for further testing or referrals. Conclusion: This syndrome deserves wider recognition because it is rarely discussed in the differential diagnosis of precordial pain. Pediatricians report that precordial catch accounts for 80% to 90% of chest pain once any chest trauma is excluded
