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: Thirty legs in nineteen patients, eleven with bilateral and eight with unilateral chronic anterior-compartment syndrome, were treated by fasciotomy. In addition, five of these patients (six legs) had compression of the superficial peroneal nerve: two before and three after fasciotomy. One patient also had lateral compartment syndrome in one leg. The patients who had compression of the superficial peroneal nerve were relieved by partial fasciectomy and fasciotomy of the lateral compartment. In one of these patients, with bilateral nerve compression, both superficial peroneal nerves were anomalous. The patient who had lateral compartment syndrome was relieved by fasciotomy of this compartment. Two patients required a second fasciotomy due to recurrence of the chronic compartment syndrome. At an average length of follow-up of twenty-five months after fasciotomy for anterior compartment syndrome, functional capacity was unlimited or increased in eighteen patients (twenty-eight legs) and was unchanged in one patient (two legs) who had had compression of the superficial peroneal nerve. The intramuscular pressures in the anterior compartment were normal at rest as well as during and after exercise eight months after the original fasciotomy in twenty-eight legs and eight months after the second fasciotomy in two legs.
Which is the apt title for the abstract? option1: Chronic anterior-compartment syndrome of the leg. Results of treatment by fasciotomy. option2: One-stage plastic reconstruction of a totally amputated cancerous penis using a unilateral myocutaneous gracilis flap.
Example Output: Chronic anterior-compartment syndrome of the leg. Results of treatment by fasciotomy.

Example Input: Abstract: The development of mouse and human embryos was assessed in human amniotic fluid to determine its suitability as a culture medium for human in vitro fertilization (IVF). Two-cell mouse embryos developed to blastocysts after 72 hours at rates similar to that in Whittingham's T6 + 10% fetal calf serum. Significantly more mouse embryos hatched in amniotic fluid. No difference was found between individual patient's amniotic fluids obtained at 16 to 21 weeks' gestation. A preliminary trial comparing amniotic fluid with T6 + maternal serum in human IVF showed no significant difference in fertilization rate and embryo development during 42 to 48 hours in vitro. Expanded blastocysts were obtained in amniotic fluid after 5 days in vitro. Four pregnancies were obtained in 9 patients' transferred embryos grown in amniotic fluid and with 2 or 12 patients' transferred embryos grown in T6 + maternal serum.
Which is the apt title for the abstract? option1: The successful use of human amniotic fluid for mouse embryo culture and human in vitro fertilization, embryo culture, and transfer. option2: National survey of writers of dean's letters for residency applications.
Example Output: The successful use of human amniotic fluid for mouse embryo culture and human in vitro fertilization, embryo culture, and transfer.

Example Input: Abstract: Two patients with Behcet's syndrome had severe esophageal involvement. Both presented the complete clinical pattern (oral, genital, and eye lesions) of Behcet's syndrome. In both, esophageal lesions were associated with other gastrointestinal manifestations, in the first a transient episode of ulcerative ileitis, and in the second patient colitis. In both, the differential diagnosis with inflammatory bowel disease was very difficult. Histology of esophageal lesions was nonspecific; no vasculitis was found. Both patients improved on steroid therapy. Esophageal lesions also improved endoscopically and histologically with steroid therapy. When there is obvious gastrointestinal involvement in Behcet's syndrome, the differential diagnosis from inflammatory bowel disease is very difficult.
Which is the apt title for the abstract? option1: Esophageal involvement in Behcet's syndrome. option2: India: move to stop sex-test abortion [news]
Example Output:
Esophageal involvement in Behcet's syndrome.
