[EX 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.

[EX Q]: Abstract: To determine whether there is a prognostic value in the percentage normal sperm morphologic features in a human in vitro fertilization (IVF) program, the authors conducted a prospective study in women with bilateral tubal damage. Based on the percentage of morphologically normal spermatozoa, the patients were divided into four groups: group I, normal morphologic features between 0% and 14%; group II, 15% to 30%; group III, 31% to 45%; and group IV, 46% to 60%. One hundred ninety successful laparoscopic cycles were evaluated. In group I, 104 oocytes were obtained, of which 37% fertilized, but no pregnancy resulted; in group II, 81% of 324 oocytes were fertilized, with a pregnancy rate per embryo transfer (ET) of 22%; in group III, 82% of 309 oocytes were fertilized, with a 31% pregnancy rate; and in group IV, 91% of 69 oocytes were fertilized, with a pregnancy rate of 12%. Probability models indicated that there was a clear threshold in normal sperm morphologic features at 14%, with high fertilization and pregnancy rate in the groups with normal sperm morphologic features greater than 14%.

[EX Q]: 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.
