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 cases of prostatic carcinoma metastatic to the cranium that presented with clinical and radiographic features simulating meningioma are described. The literature was reviewed, and 13 similar cases were identified. From the data gathered, we conclude that metastatic prostate cancer should be considered in the differential diagnosis of elderly males who present with characteristic clinical and radiological features of meningioma and that the classical description of meningioma is not specific.
Which is the apt title for the abstract? option1: Cranial metastases from prostate cancer simulating meningioma: report of two cases and review of the literature. option2: A novel human gene closely related to the abl proto-oncogene.

Q: Abstract: Ewes were treated systemically during the periovulatory period with the antihistamines diphenhydramine (H1-receptor antagonist) and(or) cimetidine (H2-receptor antagonist). None of the treatments prevented ovulation. However, the combination of drugs inhibited subsequent function of the corpus luteum (CL) as assessed by serum measurements of progesterone. Administration of antihistamines did not alter pituitary secretion of LH. Injection of small quantities of diphenhydramine and cimetidine into the antrum of the preovulatory follicle also caused aberrant luteal activity, but no blockade of ovulation. Intrafollicular injection of histamine reversed the inhibitory influence of antihistamines on the CL. Antihistamines suppressed preovulatory thecal edema and antral influx of plasma transudate containing LH. Thus, the effects of antihistamines appear to have been exerted at the follicular level. Function of matured CL was not compromised by peripheral administration of antihistamines. Actions of histamine within the preovulatory ovine follicle do not appear to be a prerequisite for ovulation, but apparently do have an impact on ensuing luteal function. We propose that a hyperemic reaction to histamine in preovulatory follicles enhances vascular filtration of LH. As a consequence, maximal permeation of the avascular granulosal layer of the follicle by LH leads to a normal luteinization response.
Which is the apt title for the abstract? option1: Ovarian function in ewes treated with antihistamines. option2: Therapy-related leukemia and myelodysplastic syndrome: clinical, cytogenetic, and prognostic features.

A: Ovarian function in ewes treated with antihistamines.

Q: Abstract: Grevillea 'Robyn Gordon' is an Australian hybrid plant which may cause allergic contact dermatitis. Over the past 8 years, it has been planted extensively in Australia and is now being exported to the United States and other Western countries. Recently, an explosion in incidence of contact dermatitis due to this plant has been seen. 24 patients who were suspected of being sensitive to it were patch tested to fresh plant and extracts with confirmation of sensitivity. A cross sensitivity to Toxicodendron was demonstrated clinically and on patch testing. The allergen in Toxicodendron, 3 pentadecylcatechol, is closely linked in chemical structure to 5-pentadecylresorcinol, present in Grevillea banksii and tridecylresorcinol in Grevillea robusta. Patch testing in patients sensitive to Grevillea 'Robyn Gordon' with tridecylresorcinol produced positive reactions, thus implicating the sensitizing role of long chain alkyl resorcinols in Grevillea 'Robyn Gordon' allergy. There is a likelihood that this sensitizing potential extends to other plants of the Grevillea genus, e.g., Grevillea robusta. With the spread of Grevillea 'Robyn Gordon' to other markets, this problem will become increasingly common.
Which is the apt title for the abstract? option1: Contact dermatitis from Grevillea 'Robyn Gordon'. option2: A consultant's survey of the patients in a maximum security hospital.

A:
Contact dermatitis from Grevillea 'Robyn Gordon'.
