In the development of infectious diseases at non-pregnancy and at pregnancy, correlations between bacterial flora in the vagina and portio vaginalis and the ascending infections of those bacteria have recently been discussed. To clarify the cause of those infectious diseases, we studied the localization of microorganisms in genital regions. Patients(More)
One hundred and forty-three women in the early first trimester of gestation were examined 364 times using transvaginal sonography, and the development of embryonic heart rate was studied. In each case gestational age was revised retrospectively by either recorded basal body temperature or ultrasound crown-rump length dating between 9 and 10 weeks. Embryonic(More)
Most chromosomal trisomies lead to miscarriages. In all trisomies, trisomy 1 is the most rare case. We herein present a patient who demonstrated a gestational sac and a yolk sac on transvaginal ultrasound. However, at 53 days of gestation, the pregnancy was lost with a diagnosis of a blighted ovum. A D&C was recommended and performed. A cytogenetic analysis(More)
In the present study, characterization of the androgen binding components in human term placenta was undertaken. Scatchard analysis revealed the presence of high affinity binding components with dissociation constants (Kd) of 1.5 X 10(-10)M and 3.7 X 10(-9)M for dihydrotestosterone (DHT) in hormone-striped placental cytosol. Isoelectric focusing (IEF) after(More)
We evaluated the clinical efficacy and safety of intramuscular (as a new route of administration) imipenem/cilastatin sodium (IPM/CS) in patients with intrauterine infections which are typical in the field of obstetrics and gynecology. The obtained results are summarized as follows. 1. Twenty-seven patients were treated with IPM/CS, 250 mg/250 mg b.i.d. (3(More)
AIM To ascertain whether premature rupture of membranes (PROM) independently affects the risk of neonatal respiratory morbidity at 32-41 weeks' gestation because previous reports have given insufficient consideration to the mode of delivery and labor onset. METHODS Data on 4,629 consecutive singleton infants were retrospectively collected. Respiratory(More)
We report on a sporadic case of hitherto unknown lethal skeletal dysplasia. The cardinal clinical manifestations consisted of frontal bossing, cloudy corneae, low nasal ridge, and micrognathia, hypoplastic thorax, and rhizomelic micromelia. Laryngoscopy and neck CT disclosed laryngeal stenosis, and brain CT demonstrated hypoplasia of the corpus callosum.(More)
Clinical effects of combined use of aztreonam (AZT), amikacin (AMK) and clindamycin (CLDM) in 46 cases with infectious diseases in obstetrics and gynecology were retrospectively studied in 2 groups, and the following results were obtained. 1. No significant difference in efficacy rates was noted between AZT plus CLDM treated group (n = 25) and AMK plus CLDM(More)
We studied clinical effects of ceftazidime (CAZ) alone or in combination with aspoxicillin (ASPC) against various infections in obstetric and gynecological patients. 1. Obstetric and gynecological patients (n = 91) with various infectious diseases were treated with CAZ alone (1-2 g x 2/day, n = 54) or in combination with ASPC (1-2 g x 2/day, n = 37)(More)
