Magnetic auditory source imaging in macaque monkey.
We recorded magnetic auditory evoked fields from the left hemisphere of a 2-year-old 3.4 kg Macaca nemestrina monkey. Three separate components were isolated from each of three data sets with latencies of approximately 22 ms, 46 ms, and 130 ms after stimulus onset. The 46 ms latency component had clear extrema values and was selected for localization. Field values from 21 recording points were used to estimate the 3-D source location of the 46 ms latency component, termed the M46. High resolution MR images of the brain provided information for correlation of neuroanatomic structure with source location. The neuroanatomic source was found to lie in the superior aspect of the temporal lobes bilaterally. We believe the M46 is the macaque analog of the human M100. Recording of auditory evoked fields in nonhuman primates offers a valuable animal model for studying neurophysiology of human magnetoencephalographically (MEG) determined auditory sources.

Mixed germ cell malignancy of the ovary concurrent with pregnancy.
BACKGROUND: A rare malignant germ cell tumor of the ovary during pregnancy was detected by screening of maternal serum alpha-fetoprotein (MSAFP). Treatment of this uncommon tumor during pregnancy incorporated combination chemotherapy including etoposide. CASE: An 18-year-old primiparous woman undergoing antenatal genetic screening was found to have an extremely elevated MSAFP of 477.8 IU/mL, or 12.46 multiples of the median. Oophorectomy and staging laparotomy at 20.5 weeks' gestation resulted in the diagnosis of mixed germ cell tumor of the ovary, with both endodermal sinus tumor and grade 3 immature teratoma. The patient received three courses of cis-platinum, etoposide, and bleomycin. Maternal serum AFP titers had returned to normal pregnancy levels by the start of the second course. A healthy female infant was delivered at 39 weeks' gestation following induction of labor for pregnancy-induced hypertension. CONCLUSION: Elevated MSAFP levels may be a presenting sign of malignant ovarian germ cell neoplasms. This report describes both surgical and chemotherapeutic treatment of a germ cell malignancy during pregnancy, with delivery at term. To date, major fetal toxicity from chemotherapy has not been identified.

Cervical conization: cold knife and laser excision in residency training.
During a 2-year period, 293 consecutive conizations performed by residents in obstetrics and gynecology were reviewed. One hundred sixty-one patients underwent laser excision and 132 women were treated by cold knife conization. Average operating times for laser excision and knife conization were 31 and 33 minutes, respectively. Combined minor and major complication rates for laser and knife cones were 19 and 30%, respectively. Major complications including cervical stenosis and heavy bleeding were seen in 20% of knife conizations and 6% of laser excisions. Average blood loss for knife conization was 65 mL, and average blood loss for laser conization was 34 mL. Among those examined in follow-up with cervical cytology and colposcopy, no patient in the laser excision group showed evidence of persistent dysplasia, compared with one patient (3%) in the knife conization group. The reported data suggest no difference in operating time, length of anesthesia, or success of treatment between laser excision and knife conization performed by residents in training. Fewer complications were seen in the laser excision group.
