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: The authors present the case of a 25-year-old man with idiopathic pachymeningitis hypertrophica that caused cervical radiculopathy. Decompressive surgery produced significant neurological improvement. The etiology and management of the condition are discussed and the literature is reviewed.
Which is the apt title for the abstract? option1: Pachymeningitis cervicalis hypertrophica. Case report. option2: Peripartum colloid osmotic pressures: correlation with serum proteins.
Example Output: Pachymeningitis cervicalis hypertrophica. Case report.

Example Input: Abstract: Fast arm movements involving the shoulder and elbow joints have been analysed in normal controls and in patients with Parkinson's disease. The subjects were requested to draw on a graphic tablet triangles and squares of different size and shape. The patients produced a larger number of EMG burst compared with controls. The movements were accurate, and each segment of the geometric figures was performed with a roughly straight trajectory, but the time necessary to trace the geometric figures and the pauses at the vertices were prolonged. We conclude that in Parkinson's disease the disability in generating two joint ballistic movements depends on a difficulty in running motor programmes for complex trajectories.
Which is the apt title for the abstract? option1: Fast complex arm movements in Parkinson's disease. option2: Quantitative computed tomography in dementia of the Alzheimer type.
Example Output: Fast complex arm movements in Parkinson's disease.

Example Input: Abstract: The pharmacokinetics of the long-acting anticholinesterase drug, galanthamine, were investigated in eight patients. After i.v. injection of 0.3 mg kg-1, the decrease in the serum concentration of galanthamine followed a biexponential curve. The serum concentration decreased rapidly from 543 +/- 47 ng ml-1 to 128 +/- 14 ng ml-1 between 2 and 30 min with a T1/2 alpha of 6.42 +/- 2.15 min, and then declined more slowly with a T1/2 beta of 264 +/- 28 min. Total serum clearance of galanthamine amounted to 5.37 +/- 0.87 ml min-1 kg-1, and the renal clearance was 1.36 +/- 0.10 ml min-1 kg-1. The cumulative urinary excretion of galanthamine between 0 and 48 h after injection amounted to 28.0 +/- 5.4% of the administered dose. The biliary excretion of galanthamine during 24 h amounted to 0.2 +/- 0.1% of the dose. There was no evidence of glucuronide or sulphate conjugation of galanthamine.
Which is the apt title for the abstract? option1: Pharmacokinetics of galanthamine (a long-acting anticholinesterase drug) in anaesthetized patients. option2: Correlation between vitiligo antibodies and extent of depigmentation in vitiligo.
Example Output:
