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).

Input: Consider Input: Abstract: Acute colitis occurred after a Hibiclens cleanser enema. Endoscopic and histologic features were not helpful in distinguishing this colitis from an infectious or idiopathic colitis, and a careful history proved invaluable. We review the complications of using soapsuds and various chemical-containing enemas; these complications range from mild colitis to death. Because soap and other chemicals are damaging to colonic mucosa, these enemas should be included as a cause of acute colitis.
Which is the apt title for the abstract? option1: Colitis after Hibiclens enema. option2: Fluoridation [letter]

Output: Colitis after Hibiclens enema.

Input: Consider Input: Abstract: The selection of assessment procedures for the preclinical evaluation of haemosorbents and the relationship between such procedures and the intended application are exemplified by examination of the design and utilization of procedures based on the rat. Procedures are described for haemoperfusion and for membrane plasma separation followed by on-line sorbent treatment of plasma (plasma perfusion). These procedures are suitable for single or repeated use, with the animal in an unrestrained and conscious state. The relevance to the intended application is demonstrated with respect to artificial liver support by the ability of rat extracorporeal circuits to provide information on the relationship between sorbent properties and liver regeneration as determined by the proliferative response following partial hepatectomy.
Which is the apt title for the abstract? option1: Preclinical evaluation of haemosorbents. option2: Impact of worksite health promotion on health care costs and utilization. Evaluation of Johnson & Johnson's Live for Life program.

Output: Preclinical evaluation of haemosorbents.

Input: Consider Input: Abstract: In 37 patients with seemingly localized non-Hodgkin's lymphoma of the Waldeyer's ring (WR-NHL), lymphangiography (LAG) and/or gallium-67 scans (Ga-67 scans) were done. Before these procedures, 20 patients were diagnosed as Stage I, and 17 as Stage II. LAG was done for 30, and Ga-67 scans for 32, 25 of whom had both. Five patients (16%) were upstaged to Stage III or IV by Ga-67 scans. Only one (3%) had abnormal LAG findings, in whom Ga-67 scans also showed abnormal accumulation in the para-aortic region. Because of this low positive rate, LAG is not recommended for staging of WR-NHL.
Which is the apt title for the abstract? option1: Value of gallium scans and lymphangiography in non-Hodgkin's lymphoma of the Waldeyer's ring. option2: Vitamin A and cancer [letter]
Output: Value of gallium scans and lymphangiography in non-Hodgkin's lymphoma of the Waldeyer's ring.
