Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

Example Input: Abstract: A patient is presented in whom endotracheal intubation was impossible secondary to an obstructing substernal goiter and laryngeal spasm. Cardiopulmonary bypass was utilized to provide safe induction of anesthesia and intubation so that the substernal goiter could be removed. Other alternative methods in anesthetic management are discussed.
Which is the apt title for the abstract? option1: The impossible intubation--what next? option2: Effects of exercise and carbohydrate composition on gastric emptying.
Example Output: The impossible intubation--what next?

Example Input: Abstract: After initiation of ibuprofen therapy, a 45-year-old woman developed muscle weakness and tenderness with rhabdomyolysis, culminating in respiratory failure. A muscle biopsy specimen showed a vacuolar myopathy, and markedly decreased muscle carnitine content and carnitine palmitoyltransferase activity. Following recovery, muscle carnitine content was normal but carnitine palmitoyltransferase activity was still abnormally low. The ratio of palmitoyl-coenzyme A plus carnitine to palmitoylcarnitine oxidation by muscle mitochondria isolated from the patient was markedly decreased. We conclude that transiently decreased muscle carnitine content interacted with partial deficiency of carnitine palmitoyltransferase-A to produce rhabdomyolysis and respiratory failure and that ibuprofen may have precipitated the clinical event.
Which is the apt title for the abstract? option1: Partial muscle carnitine palmitoyltransferase-A deficiency. Rhabdomyolysis associated with transiently decreased muscle carnitine content after ibuprofen therapy. option2: Use of thermogram in detection of meningitis.
Example Output: Partial muscle carnitine palmitoyltransferase-A deficiency. Rhabdomyolysis associated with transiently decreased muscle carnitine content after ibuprofen therapy.

Example Input: Abstract: The cases of two patients in whom complete but transient quadriplegia developed after an injury that was incurred while playing football are presented. Both patients were found to have a congenitally narrow cervical vertebral canal. Critical stenosis resulting in the transient quadriplegia occurred after a presumed injury to a cervical disc. In our opinion, a myelogram should be made for patients with a history of transient quadriplegia, numbness, or a burning sensation down the back or the lower extremities, even if other radiographic studies are interpreted as negative. Patients who have stenosis of the cervical spine should be advised to discontinue participation in contact sports.
Which is the apt title for the abstract? option1: Congenital cervical stenosis presenting as transient quadriplegia in athletes. Report of two cases. option2: Primary teratocarcinoma of the lung.
Example Output:
Congenital cervical stenosis presenting as transient quadriplegia in athletes. Report of two cases.
