TASK DEFINITION: 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).
PROBLEM: Abstract: Eighty-two women with symmetric cornual blockage were selected for evaluation of the results of microsurgical anastomosis in relation to data from preoperative hysterosalpingography and histologic study of excised tubal specimens. Serial sections from 164 occluded tubal portions were examined. The term pregnancy rate was 44%. Several prognostic factors influencing the postoperative pregnancy rate were revealed: maximized tubal length; preserved intramural portion; absence of chronic inflammation; absence of tubal inclusion in the tubal wall; and absence of tubal endometriosis.
Which is the apt title for the abstract? option1: Prognostic factors influencing the pregnancy rate after microsurgical cornual anastomosis. option2: Fracture dislocation of the femoral head treated by open reduction and internal fixation.

SOLUTION: Prognostic factors influencing the pregnancy rate after microsurgical cornual anastomosis.

PROBLEM: Abstract: The authors have investigated the application of mode-locked and Q-switched Neodymium:YAG (Nd:YAG) lasers in ocular surgery by means of high-speed photography and hydrophone measurements. The incisive effect relies on the optical breakdown at the laser focus. Cavitation bubbles and acoustic transients are thereby generated. Their size and pressure amplitude have been measured at various laser-pulse energies. With a pulse energy of 5 mJ, the bubble is 1.5 to 2.3 mm in diameter and the pressure of the acoustic transient is 9 to 16 bar (130 to 230 psi) at a distance of 18 mm from the focal point. Bubble size and amplitude of the pressure pulse are always approximately 50% higher with a Q-switched laser than with a mode-locked laser. However, the size of the ruptures produced in a polyethylene membrane by the laser pulses is the same for both modes of operation. The energy balance shows that not only mechanical effects, but also thermal mechanisms are responsible for photodisruption.
Which is the apt title for the abstract? option1: Cavitation bubble dynamics and acoustic transient generation in ocular surgery with pulsed neodymium: YAG lasers. option2: The management of patients with back pain and idiopathic vertebral sclerosis.

SOLUTION: Cavitation bubble dynamics and acoustic transient generation in ocular surgery with pulsed neodymium: YAG lasers.

PROBLEM: Abstract: The advent of ultrasound recording has expanded the capabilities for treatment of the fetus in utero. The diagnosis of specific disease processes has allowed for prenatal intervention by new techniques designed to improve fetal survival. The application of ventricular pacing in a hydropic fetus with complete atrioventricular (AV) block is reported. Complete AV block resulted from maternal collagen vascular disease. The application of ventricular pacing was to allow for further in utero development and for reversal of hydrops fetalis after improvement in cardiac output. Despite fetal death 4 hours after placement of the ventricular pacing lead, this procedure when applied earlier in the development of hydrops may allow for fetal survival. Ventricular pacing was accomplished without apparent trauma to mother or fetus and no evidence of fetal injury was seen at necropsy. Therefore, in the fetus who would otherwise die in utero before the point of viability ex utero, fetal ventricular pacing may be a rational alternative to current observation.
Which is the apt title for the abstract? option1: Fetal ventricular pacing for hydrops secondary to complete atrioventricular block. option2: Tax gasoline to save lives [letter]

SOLUTION:
Fetal ventricular pacing for hydrops secondary to complete atrioventricular block.
