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).

Q: Abstract: Two men, aged 25 and 33 years, had progressive hemidystonia and an arteriovenous malformation (AVM) in the contralateral cerebral hemisphere. One patient with an AVM in the posterior basal ganglia of the right hemisphere had an older brother with severe generalized dystonia. The second patient had an AVM in the left cortical and subcortical parietal area with no obvious lesion in the basal ganglia. Unlike generalized dystonia, a focal lesion is commonly found in patients with unilateral dystonia. The association of AVM-induced hemidystonia and family history of dystonia suggests that genetic predisposition may be important in some patients with hemidystonia.
Which is the apt title for the abstract? option1: Arteriovenous malformation presenting as hemidystonia. option2: Bacteremia during bronchoalveolar lavage.

A: Arteriovenous malformation presenting as hemidystonia.

Q: Abstract: Little is known about the reflex effect on airway caliber evoked by stimulation of phrenic afferents. Therefore, in chloralose-anesthetized, paralyzed dogs, we recorded airflow, airway pressure, arterial pressure, and heart rate while electrically stimulating a phrenic nerve. Total lung resistance was calculated breath by breath. The phrenic nerve was stimulated at 3, 5, 20, 70, 140, and 200 times motor threshold and the compound action potential was recorded. Stimulation of the phrenic nerve at three and five times threshold, which activated groups I, II, and a few group III fibers, had no effect on any of the variables measured. Stimulation at 20 times threshold, which activated many group III fibers and groups I and II fibers, reflexly decreased resistance. Stimulation at 70, 140, and 200 times threshold, which activated groups I-IV fibers, evoked progressively greater decreases in lung resistance. The reflex bronchodilation evoked by phrenic nerve stimulation was unaffected by propranolol or phentolamine but was abolished by atropine. We conclude that activation of groups III and IV phrenic nerve afferents reflexly decreased total lung resistance by withdrawing cholinergic tone to airway smooth muscle.
Which is the apt title for the abstract? option1: Stimulation of groups III and IV phrenic afferents reflexly decreases total lung resistance in dogs. option2: Drug-induced cutaneous reactions. A report from the Boston Collaborative Drug Surveillance Program on 15,438 consecutive inpatients, 1975 to 1982.

A: Stimulation of groups III and IV phrenic afferents reflexly decreases total lung resistance in dogs.

Q: Abstract: A 1.5-year-old girl presented with a peripheral iris mass. When the girl was 3 years old, the lesion was excised after it had manifested significant growth. A stalk of fibrovascular tissue was noted to extend from the lesion to the optic disc. Histopathologically, the tumor was a well-circumscribed, pigmented ciliary body adenoma. Electron microscopy revealed characteristic neuroepithelial melanosomes, distinct from those of choroidal melanocytes, and occasional annulate lamellae. A fibrovascular membrane extended over the tumor surface and was adherent to lens capsule. The association of this adenoma with a persistent stalk of primary vitreous indicates a congenital origin of this tumor. Both adenoma and adenocarcinoma of the pigmented and nonpigmented ciliary epithelium tend to be disorders of adults. The authors report the youngest presentation of a pigment epithelium adenoma, the only well-documented case associated with persistent hyperplastic primary vitreous, and the only documentation of annulate lamellae in a ciliary body tumor.
Which is the apt title for the abstract? option1: Fetal adenoma of the pigmented ciliary epithelium associated with persistent hyperplastic primary vitreous. option2: Operations for herniated lumbar discs. A follow-up study 2-5 years after surgery.

A:
Fetal adenoma of the pigmented ciliary epithelium associated with persistent hyperplastic primary vitreous.
