M.D. Abdullah Derin

A 28-year-old competitive freediver from the Aegean coast presented with recurrent episodes of confusion and headaches after deep dives. Dr. Derin discovered an extremely rare patent foramen ovale that only manifested symptoms under extreme pressure changes. He coordinated with cardiology to develop a conservative management plan allowing the patient to continue shallow-depth diving with strict monitoring, preserving both his livelihood and safety.

A 72-year-old retired curator of Ottoman textiles arrived with unexplained weight loss and fatigue. Her extensive international travel history complicated diagnosis until Dr. Derin identified a reactivated latent histoplasmosis infection acquired decades earlier during a research trip to South America. Treatment involved carefully balancing antifungal medications with her existing rheumatoid arthritis therapy.

A 19-year-old university student from a low-income family presented with severe abdominal pain. While initial tests suggested appendicitis, Dr. Derin noticed subtle neurological symptoms and diagnosed acute intermittent porphyria—a condition triggered by her crash diet during exams. He arranged social services support for the expensive medication and designed a dietary plan preventing future crises.

A 41-year-old professional pastry chef developed unusual skin lesions and joint pain. Dr. Derin connected these to chronic flour inhalation, diagnosing baker's asthma with associated cutaneous manifestations. The treatment involved workplace modifications, specialized respiratory protection, and collaboration with an occupational therapist to redesign his kitchen workflow.
