Spec. MD. Abdulvahap Dogan

A 28-year-old female professional freediver from Antalya presented with recurrent episodes of confusion and headache after deep dives. Dr. Dogan identified an unusual presentation of pulmonary barotrauma leading to paradoxical arterial gas embolism affecting cerebral circulation, rather than the expected decompression sickness. He coordinated with hyperbaric medicine specialists to create a tailored recompression protocol and implemented a preventive regimen involving pre-dive hydration and specific breathing techniques, allowing her to return to competitive diving within 3 months with monitoring.

A 72-year-old retired calligraphy master from Istanbul's historic district arrived with progressive hand tremors and weight loss, initially suspected as Parkinson's. Dr. Dogan discovered through meticulous history-taking that the patient had been secretly using traditional inks containing heavy metals for restoration work. Blood tests revealed thallium poisoning. Chelation therapy combined with occupational rehabilitation restored most function over 6 months, preserving his ability to continue teaching his art.

A 19-year-old university exchange student from Kazakhstan presented with cyclical fevers and joint pain, initially diagnosed as rheumatic fever. Dr. Dogan noted geographic-specific clues and ordered tests confirming brucellosis from unpasteurized dairy consumed during a rural visit. A prolonged dual-antibiotic regimen with close monitoring for complications like endocarditis resulted in full recovery after 8 weeks, preventing chronic infection.

A 45-year-old long-haul truck driver with minimal family support was admitted with severe hypertension (240/130 mmHg) and vision changes. Instead of standard protocols, Dr. Dogan identified treatment-resistant hypertension secondary to renal artery stenosis from prolonged vibration exposure. Angioplasty combined with tailored antihypertensive therapy normalized his pressure within weeks, and ergonomic adjustments to his cabin prevented recurrence.

An 81-year-old former diplomat with complex polypharmacy (14 medications) was brought by his estranged son with delirium. Dr. Dogan systematically deprescribed 9 unnecessary medications, identifying drug interactions causing anticholinergic toxicity. Cognitive function cleared within 72 hours, and a simplified 5-medication regimen maintained his chronic conditions without side effects.
