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: Vaginal discharge is a common complaint, the cause of which can be diagnosed on the basis of the distinguishing characteristics of the fluid itself, the course and symptoms of the infection, and the results of a few simple office laboratory tests. Accurate diagnosis is important because treatment can then be selected specifically rather than empirically. Optimal treatment differs with each of the four major causative agents: Candida, Gardnerella, Trichomonas, and Chlamydia. Prompt eradication of the infection promotes patient and public health.

Q: Abstract: Measurements of muscle pH (pHm) with the homogenate technique are routinely made when extensive phosphagen hydrolysis has occurred. Upon exposure of the homogenate to 37 degrees C in the pH meter, phosphocreatine and ATP were rapidly degraded to 35 and 60% of control concentrations after 30 s. Attempts at chemically arresting this hydrolysis were unsuccessful. Therefore we examined the significance of phosphagen hydrolysis on pHm measurement in human biopsies taken at rest and following intense electrical stimulation. To accomplish this, pHm was measured at 0 degree C, where extensive hydrolysis did not occur. On the same homogenate, pHm was measured at 0 degree C with phosphagens and at 0 and 37 degrees C after phosphagen hydrolysis. The effect of phosphagen hydrolysis on pHm at 0 degrees C was used to estimate this effect at 37 degrees C. In resting samples, phosphagen hydrolysis produced a nonsignificant acidification of 0.008 pH units and, in electrically stimulated samples, a nonsignificant alkalinization of 0.033 units. Measurements of homogenate PCO2 suggested that most of the CO2 remained in the sample during pHm measurement at 37 degrees C. The present work substantiates the use of the homogenate technique as an accurate and practical method for the estimation of intracellular pH in resting and exercise human muscle samples.

Q: Abstract: Neurologists in the United States were enumerated for each year from 1935 to 1984 on two bases: board certification (including Child Neurology and Psychiatry and Neurology) and completion of PG4 neurology residency training. The annual incidence of new neurologists was calculated at less than 200 until 1970; then it rose steadily to 380 in 1980, and plateaued thereafter at 385. The estimated number of neurologists present at one time (prevalence) was 1,500 in 1950, 2,400 in 1970, 4,600 in 1980, 8,100 in 1990, and 11,000 in 2000. These numbers for total neurologists will plateau at 12,200 by about 2010, at which time the number of certified neurologists will also plateau at 9,900. Both numbers are notably less than our prior estimate of needs: 16,500 neurologists by 1990, 19,100 in 2010.
Which is the apt title for the abstract? option1: Neurologists in the United States--past, present, and future. option2: Ethics, technology, and the high cost of dying: a public forum.
