Based on these initial data DWI seems to be a sensitive but unspecific modality for the detection of locoregional or metastatic BC disease. There was no possibility to quantitatively distinguish lesions using ADC. DWI alone may not be recommended as a whole-body staging alternative to FDG PET(/CT). Further studies are necessary addressing the question of whether full-body MRI including DWI may become an alternative to FDG PET/CT for whole-body breast cancer staging.
Though more accurate compared to ultrasound for evaluating the axillary lymph node status FDG-PET/CT is only as sensitive as ultrasound when it comes to the detection of axillary lymph node metastases. Due to the low sensitivity FDG-PET/CT cannot act as a substitute for Sentinel lymph node biopsy. FDG-PET/CT is able to detect previously unknown locoregional extra-axillary lymph node metastases.
Recurrent vulvovaginal candidosis is a frequent disease with a serious impact on women's quality of life. Mostly, recurrences are caused by identical Candida strains suggesting C. albicans persistence in the female anogenital area. Objectives of the presented work were to identify the site of C. albicans persistence, to determine clinical symptoms and signs related to C. albicans positive vulvar cultures and to introduce a new therapeutic approach in women with RVVC. Women with an acute, culture-confirmed episode of RVVC at time of visit were included in this prospective case series. Swabs were obtained from both vagina and inter-labial sulcus. Women received a combined 20-day regimen of 100 mg oral fluconazole and ciclopiroxolamin cream topically. Follow-up visits were at 3, 6, 9 and 12 months. Of 139 women, 105 (76%) had at least one C. albicans positive culture from the external vulva. Vulvar positive cultures correlated with pruritus (OR 5.4; P < 0.001), vulvar edema (OR 3.8; P = 0.03) and fissures (OR 2.4; P = 0.03). Recurrence rates were 27%, 33% and 34% (at 6, 9, 12 months, respectively). The external vulva appears to represent a site of C. albicans persistence and source of endogenous re-infection in patients with RVVC. The combined treatment compared favorably with published fluconazole maintenance regimens.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
