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).

Input: Consider Input: Abstract: Lesions in the pedicles of the cervical spine are both a diagnostic and technical challenge. An osteoid osteoma of the pedicle of the fourth cervical vertebra occurred in a 17-year-old girl. Resection of the tumor adjacent to the dura medially and the vertebral artery anterolaterally was accomplished via a transpillar approach. The transosseus approach preserved the facet joints and posterior elements and obviated the need for an interbody fusion.
Which is the apt title for the abstract? option1: Osteoid osteoma in a cervical pedicle. Resection via transpillar approach. option2: Selective binding of colloidal gold-protein conjugates to epidermal phosphorus-rich keratohyaline granules and cornified cells.

Output: Osteoid osteoma in a cervical pedicle. Resection via transpillar approach.

Input: Consider Input: Abstract: Boerhaave's syndrome represents a diagnostic dilemma for the emergency physician. The prognosis of this truly life-threatening emergency is darkened by any significant diagnostic delay. Unfortunately, classic or expected symptoms and signs are frequently absent at presentation, a circumstance that leads to frequent misdiagnosis. Two cases of Boerhaave's syndrome with "atypical" clinical presentations are reviewed and discussed. It is clear that Boerhaave's syndrome should always be suspected in the evaluation of any sudden chest, abdominal, or back pain associated with emesis. However, emphasis should be placed on the fact that this entity may occur without emesis. The chest radiograph is the most helpful diagnostic aid. Undoubtedly, maintenance of a high degree of suspicion by the emergency physician for Boerhaave's syndrome will lead consistently to earlier diagnosis, and subsequent aggressive intervention should result in considerable reduction in rates of both morbidity and mortality.
Which is the apt title for the abstract? option1: Boerhaave's syndrome: an elusive diagnosis. option2: Use of high speed centrifugation in early detection of bacteraemia.

Output: Boerhaave's syndrome: an elusive diagnosis.

Input: Consider Input: Abstract: Rehabilitation of the patient with arthritis is a multifaceted process that should always involve patient, family, and a wide variety of healthcare professionals and community organizations. The optimal goal is to improve the patient's functional performance. Success depends on correct identification of functionally limiting problems.
Which is the apt title for the abstract? option1: Arthritis rehabilitation. A multifaceted process. option2: Testosterone enhancement of thyroid carcinoma in rats: the role of TSH.
Output: Arthritis rehabilitation. A multifaceted process.
