Input: Consider Input: Abstract: From February 1984 to March 1986, 28 patients underwent a new technique of coarctation repair. This technique consists of a complete mobilization of the left subclavian artery extended to the origin of its first branches. The aorta need not be extensively mobilized and the intercostal arteries are individually controlled with snares. After all the proper clamping, the left subclavian artery is detached from the aorta at its origin and is opened longitudinally on its posterior aspect. The anterior wall of the aorta is then incised, beginning with the opening at the origin of the left subclavian artery and extending distally to the descending aorta 12 to 15 mm past the coarctation. The coarctation membrane is excised and the ductus is ligated and divided. The opened left subclavian artery, now forming a flap, is pulled down and sutured to the edges of the aorta, widening the coarctation site and also preserving the blood flow to the left arm. The ages of the patients ranged from 2 months to 25 years (mean 4.24 +/- 4.9 years) and their weights ranged from 2.8 to 52 kg (mean: 14.8 +/- 10.0 kg). There were no hospital deaths and the mean follow-up was 9.6 months (+/- 4.9 months). Recatheterization of four patients from 4 to 12 months postoperatively showed adequate correction and strongly suggested normal growth of the aorta at the site of coarctation, as well as preservation of the blood flow through the left subclavian artery. Doppler measurements showed normal flow to the left arm and no gradients through the isthmic area. Our experience indicates that this technique is not only feasible but is the procedure of choice in most cases of discrete isthmic coarctation and in some cases of long narrowing of the isthmus in patients with a wide range of ages and weights.
Which is the apt title for the abstract? option1: A new technique for repair of aortic coarctation. Subclavian flap aortoplasty with preservation of arterial blood flow to the left arm. option2: Target-specific nerve regeneration through a nerve guide in the rat.

Output: A new technique for repair of aortic coarctation. Subclavian flap aortoplasty with preservation of arterial blood flow to the left arm.

Input: Consider Input: Abstract: In recent years it has become increasingly apparent that cough is frequently the sign of airway hyperreactivity. While the association between cough and wheezing is well recognized in asthmatics, cough may be the only clinical manifestation of this problem. Emergency physicians frequently have occasion to evaluate the coughing patient. Awareness of this clinical entity should facilitate appropriate evaluation, management, and referral of these patients.
Which is the apt title for the abstract? option1: Cough variant asthma [published erratum appears in Pediatr Emerg Care 1987 Mar;3(1):9] option2: Prediction and evaluation of brainstem function by auditory brainstem responses in patients with uncal herniation.

Output: Cough variant asthma [published erratum appears in Pediatr Emerg Care 1987 Mar;3(1):9]

Input: Consider Input: Abstract: Spontaneously hypertensive rats (SHR) have several abnormalities of calcium metabolism compared with normotensive control Wistar-Kyoto (WKY) rats. Previously the vitamin D metabolite 1,25-dihydroxycholecalciferol (1,25[OH]2D3) was found to be inappropriately low in SHR in view of their ionized hypocalcemia and hyperparathyroidism. We examined the responses of plasma 1,25(OH)2D3 to several known stimuli. Baseline plasma 1,25(OH)2D3 levels tended to be lower in SHR than WKY rats (51.5 +/- 4.3 vs. 82.3 +/- 14.1 pg/ml, P = 0.06). Infusion of a pharmacologic dose of parathyroid hormone (8 U/hr over a period of 17 hours) resulted in a plasma 1,25(OH)2D3 level of 504 +/- 77 pg/ml in SHR vs. 1016 +/- 211 pg/ml in WKY rats (P less than 0.03). Cyclic adenosine monophosphate infusion (1 mumol/hr/100 gm over a period of 17 hours) in thyroparathyroidectomized animals resulted in a 1,25(OH)2D3 level of 121 +/- 24 pg/ml in SHR vs. 557 +/- 26 pg/ml in WKY rats (P less than 0.01). After dietary phosphorus depletion for 3 weeks, SHR also had lower 1,25(OH)2D3 levels than WKY rats (83 +/- 13 vs. 300 +/- 42 pg/ml, P less than 0.001) even though a comparable degree of hypophosphatemia was achieved. Thus, the response of plasma 1,25(OH)2D3 levels to several known stimuli is submaximal in SHR as compared with WKY rats, suggesting defective synthesis or enhanced metabolic clearance of this hormone.
