A 69-year-old postmenopausal female with a spontaneously occurring uterine pyomyoma was described with emphasis on the MR imaging findings. On unenhanced T1- and T2-weighted MR images, a huge mottled mass suspected to contain blood products, necrotic tissue, or purulent or viscous fluid was demonstrated within anterior myometrial wall of uterine body. The mass was surrounded by a peripheral rim that was hyperintense on T1-weighted images and hypointense on T2-weighted images. On gadolinium-enhanced MR images, most of the mass was unenhanced, but the peripheral rim was equally enhanced with the surrounding myometrium. Pathological examination revealed an intramural uterine pyomyoma surrounded by fibrous capsules with abundant lymphocytes and neutrophils. Our findings indicate that pyomyoma should be considered when MR images demonstrate a myometrial cystic lesion accompanied by a peripheral rim.

Prevotella bivia is common in pelvic inflammatory diseases. Parenteral antimicrobial agents have been widely used against those infections. We investigated the bactericidal activities of three cephalosporins, i.e. cefluprenam (CFLP), ceftazidime (CAZ) and cefotaxime (CTX) and of two other antimicrobial agents, i.e. clindamycin (CLDM) and imipenem (IPM) against P. bivia. We also investigated the in vitro morphological changes induced by these agents in P. bivia. Cephalosporins exhibited bactericidal activities against P. bivia and induced time- and concentration-dependent morphological changes in P. bivia (filamentation). CLDM and IPM also had bactericidal activities, but induced different morphologic alterations: formation of spheroblasts and lysis. These results confirm the fact that each antimicrobial agent has characteristic aspects.

Ravuconazole (BMS 207147, ER-30346) is a long-lasting triazole antifungal agent active against a broad spectrum of fungal pathogens including non-albicans Candida, Aspergillus, Cryptococcus and key dermatophytic fungi. The penetration of ravuconazole into rat tissues was examined. Fifty-five 7-week-old specific pathogen free female rats were used in this study. Plasma, lung and uterus tissue of rats were taken at 1, 2, 4, 8, 12, 16, 24, 32, 48, 60, and 72 h (n = 5) after oral administration of 10 mg/kg of ravuconazole. The quantitative assays of ravuconazole by HPLC after the extraction with diethylether were conducted for each tissue sample homogenate. tmax, t _1/2, and Cmax of ravuconazole is 8 h, 16.9 h and 1.68 µg/ml, respectively. The concentrations of ravuconazole in rat uterus and lung tissues were 2–to 6 times higher than the corresponding blood concentrations. The ratio of plasma to lung levels of ravuconazole was superior to the published data of other azoles. Considering its antifungal spectrum, ravuconazole would thus be a good candidate for treatment of deep-seated fungal infections caused by Candida, Aspergillus and Cryptococcus.

Objective: A study was carried out to compare three treatment regimens for vaginal candidiasis. Methods: A total of 150 women with clinical and mycological evidence of vaginal candidiasis were randomized to receive daily a 200-mg dose of oral itraconazole for 3 days (50 women), a single oral 150 mg dose of fluconazole (50 women), or daily 100 mg dose of intravaginal clotrimazole for 6 days (50 women). They were assessed at 5–15 days (short-term assessment) and again at 30–60 days (long-term assessment) after discontinuation of the treatment. Results: At the short-term or long-term assessment, Candida species were completely eradicated from the vagina in 80 or 74% in the 3-day oral itraconazole group, 76 or 70% in the single oral fluconazole group, and 72 or 60% in the intravaginal clotrimazole group, respectively. The rates of clinical effectiveness were 92 or 88% in the 3-day oral itraconazole group, 80 or 76% in the single oral fluconazole group, and 72 or 58% in the intravaginal clotrimazole group, respectively. Treatment-related side effects were not found in any group. Conclusions: Our study suggests that the treatment of vaginal candidiasis with oral itraconazole or oral fluconazole would be effective and that an oral itraconazole or fluconazole therapy might be one choice in the treatment of vaginal candidiasis.

That no significant decrease of uterine enhancement rate was found after surgery suggests the uterine function and fertility may be preserved after ART.
