Background: The most challenging part of diabetes management for a patient with diabetes is selecting a healthy diet. The purpose of this study is to evaluate participants’ knowledge of food labels, to find out the relationship between the type of diabetes mellitus (DM) and knowledge score of food labels, and to explore the barriers that prevent patients from reading food labels. Methodology: This observational study was conducted on patients with type 1 or type 2 diabetes using a validated self-administered questionnaire. The study was conducted at diabetes clinics at King Khalid University Hospital and King Abdul-Aziz University Hospital, Riyadh, Saudi Arabia, from November 2019 to February 2020. Data were analyzed using SPSS. Results: A total of 310 participants were enrolled in this study, of which 50.3% had type 1 DM, and more than half of them were female (51.6%). Patients with type 1 DM had higher mean declarative and applied knowledge scores than those with type 2 DM, regardless of whether they were taking pre meals insulin or not. The highest proportion (39.9%) had difficulty in understanding the content of the nutrition labels, and some of them (37.2%) did not receive any educational session about it. Only 9.5% of the participants did not have any difficulties in reading food labels. Conclusion: Patients with both types of diabetes tended to have poor total knowledge about food labels and faced difficulties in reading them. Provided educational sessions by primary health care and specialized physician and DM educator about food labels are recommended to help them to choose food properly.

Vast majority of mediastinal goiters are situated in the anterior mediastinal compartment and rarely located in the posterior mediastinum. Posterior mediastinal goiters should be differentiated from other mediastinal masses through appropriate work-up by the computed tomography which is the most valuable technique. We reported a case of symptomatic mediastinal goiter extending from the neck to the posterior mediastinum compressing the trachea and airway. The surgical intervention is considered the treatment of choice in such cases. The surgical approach was done through a classical transverse cervical incision, lateral right thoracotomy, and median sternotomy. The histopathological report was consistent with a multinodular goiter. The patient's recovery was uneventful with an excellent postoperative symptomatic relief.
