G2: CASE ANALYSIS A 32-year-old Austronesian man came to our medical admissions unit with a 6- week history of exertional dyspnoea, recurring fevers, and sweats. He had a seven-year history of binge drinking, using 3-4 litres of cider every day. He smoked ten cigarettes a day, but he was generally healthy and had no serious medical or family history. The patient had no other symptoms and did not take any medications on a daily basis. Upon examination, the pulse rate was 124 beats per minute, and the blood pressure was 120 mmHg/48 mmHg. With a temperature of 38.8°C, he was diagnosed as febrile. On room air, oxygen saturations were 100% with no evidence of respiratory distress. He had a lemon yellow hue to his complexion and pale conjunctiva (but no evidence of icteric sclerae). A collapsing pulse and a mild systolic murmur audible at the left sternal border were discovered during a cardiovascular examination. The chest was auscultated and revealed vesicular breath sounds with no further noises. There were no signs of neck stiffness or skin rashes on neurological evaluation. What do you think is his condition? What vitamin deficiency is caused by it? And why?
