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: Chronic pain in the perineum is a difficult neurosurgical problem. This article evaluates the effectiveness of sacrococcygeal rhizotomy in 28 patients who had cancer-related pain or coccydynia, underwent rhizotomy, and were followed for an average of 3 years. Good pain relief was obtained in 53% (10 of 19 patients) with malignant pain, as opposed to 22% (2 of 9 patients) with nonmalignant pain. Sacral rhizotomy is a reasonable treatment for cancer-related perineal pain, but it is ineffective for coccydynia and other benign perineal pain problems.
Which is the apt title for the abstract? option1: Sacrococcygeal rhizotomy for perineal pain. option2: NIMH review of fraud charge moves slowly [news]
Example Output: Sacrococcygeal rhizotomy for perineal pain.

Example Input: Abstract: As punishment for lying, the foster mother of a five-year-old white male poured pepper into his throat. He immediately became dyspneic, then apneic, and was pronounced dead about 1 h later. At autopsy, the main stem and several smaller bronchi were occluded with pepper. Mechanisms of asphyxia by pepper include mechanical obstruction of the tracheobronchial tree and mucosal edema caused by the irritant effect of volatile oils in pepper. This rare circumstance represents the second reported fatal case of pepper aspiration and the third reported case overall.
Which is the apt title for the abstract? option1: Homicidal asphyxia by pepper aspiration. option2: Serum immunocomplexes in patients with subarachnoid hemorrhage.
Example Output: Homicidal asphyxia by pepper aspiration.

Example Input: Abstract: A 9-year review of our experience with head and neck metastases from 845 urogenital tract tumors of the kidney, prostate, bladder, testicle, spermatic cord, penis, urethra, and ureter was performed. Thirty-one (3.7%) of these tumors developed metastases to the cervical and supraclavicular lymph nodes, scalp, thyroid gland, thyroid cartilage, parotid gland, retroorbit, mandible, nasal cavity, and paranasal sinuses. Unusual cases and a review of the literature are presented. The frequency of such metastases to the head and neck from various primaries, diagnostic application of current immunohistochemical methodology, and therapeutic alternatives are emphasized.
Which is the apt title for the abstract? option1: Urogenital tract carcinoma metastatic to the head and neck. option2: Urethral disease and interventional cystourethrography.
Example Output:
Urogenital tract carcinoma metastatic to the head and neck.
