A 15-year-old young lady, Camila, was admitted through the accident and emergency department for gross haematuria for 2 days. She was a new immigrant to the city 1 month ago. She was diagnosed with tuberous sclerosis at 2 years old in her home town when she first presented as developmental delay and repeated twitching of the limbs. She was on regular anti-epileptic medications to control her seizures. She can walk independently but needs supervision in all daily activities and cannot communicate verbally. Two days ago, she was noticed to have unusual behaviour, which suggested she was not feeling well. Her pants were blood-stained, and the parents were not sure whether she had dysmenorrhea, causing her discomfort. Hence, a few tablets of painkillers were given to her for pain control. However, the bleeding increased in amount, and she looked increasingly unwell; thus, she was brought to the hospital. Upon arrival to hospital, her blood pressure was low at 80/40 mmHg with heart rate 140 bpm and oxygen saturation was 89% on 2 L/min oxygen. Based on this alarming vital signs, what underlying medical conditions or complications should be considered in Camila?
