Objectives: We aimed to identify coronary artery involvement in mustard gas-poisoned patients. Methods: We conducted a case-control study on 40 mustard gas-poisoned patients who underwent coronary artery angiography due to cardiac pain. The study was performed during a 3-year interval on patients who were referred to three main hospitals of Mashhad, Iran. The nonexposed control group consisted of 40 normal individuals who had undergone angiography for the same reasons. The primary outcome measurement was coronary artery involvement and its location. Data were collected through studying the angiography films. Results: Among the 40 poisoned patients studied, 15 (37.5%) had coronary artery ectasia, mainly in the left anterior descending artery, but 25 (62.5%) did not. The same values were 2 (5%) and 38 (95%) in the nonexposed group, respectively, which was significantly different compared to the exposed group (p = 0.001). The odds ratio was 11.40. Conclusions: The prevalence of coronary artery ectasia in mustard gas-poisoned patients was 7.5 times more than in nonexposed controls. Considering the proposed odds ratio, the occurrence of coronary artery ectasia is around 11.4 times greater in mustard gas-poisoned veterans. This is the first study to suggest a strong correlation between mustard gas poisoning and coronary artery ectasia.

Background: children are exposed to numerous chemicals, such as hand sanitizers and their associated poisoning. Awareness of such poisoning symptoms and their management is critical for healthcare providers, as it can induce dangerous conditions. This study evaluated the clinical and paraclinical parameters of children who ingested hand sanitizers. Methods: In the first 6 months of 2020, the cases of children who accidentally ingested hand sanitizer and were referred to Akbar Hospital in Mashhad City, Iran (Referral pediatric poisoning center) were evaluated in this cross-sectional study. The relevant medical information and laboratory parameters were recorded. Results: In total, 20 patients were evaluated; of whom, 80% were male. The Mean±SD age of the study subjects was 4.9±4.2 years (2-15y). The ingestion was accidental in the study participants. The amount of ingestion approximately equaled a sip (3-7cc). All clinical and laboratory parameters were normal according to their age. Only 1(5%) case presented metabolic acidosis. No study subject manifested hypoglycemia or the loss of consciousness. Thus, they only received supportive care and were observed for ≥12 hours. Conclusion: Based on the present study results and absence of symptoms in the explored cases of hand sanitizer ingestion, the suitability of hand sanitizer solutions. Therefore, the formulation of these products should be carefully evaluated
