Percutaneous Coronary Intervention of Left Main Chronic Total Occlusion in Pediatric Patients.

Percutaneous coronary intervention (PCI) in pediatric patients is rare, especially in cases of chronic total occlusion (CTO) of the left main coronary artery (LMCA), with scarce evidence. These are associated with poorer prognostic outcomes, highlighting the need for timely intervention. In addition, its unique and entirely different pathophysiology compared to that well-studied in adults makes it a clinically challenging scenario for diagnosis, treatment, and follow-up.

Retinal toxicity induced by antimalarial drugs: literature review and case report.

Antimalarial drugs are widely used in several countries for control of rheumatologic diseases such as systemic lupus erythematosus and rheumatoid arthritis. They are still used in Mexico because of their low cost and few secondary effects, most of which are mild and reversible. Even so, at an ophthalmological level, they could produce irreversible visual damage, which is why it is important to have ophthalmological evaluation and proper follow up.
