RESUMEN
BACKGROUND: Secondary vaginal stenosis may occur after reconstruction of genital malformations in childhood or after failed vaginal aplasia repair in adults. AIM: This study focusses on the results of the surgical treatment of these patients in our multidisciplinary transitional disorders/differences of sex development team of pediatric surgeons and gynecologists. METHODS: A retrospective analysis was carried out on adult and female identified disorders/differences of sex development patients with vaginal stenoses treated between 2015 and 2018 in a single center with revision vaginoplasty. The underlying type of malformation, the number and surgical techniques of vaginoplasties in infancy, techniques of revision of the stenotic vagina, vaginal length and caliber, possibility of sexual intercourse, and temporary vaginal dilatation. A review of literature with regard to recommended surgical techniques of revision vaginoplasties was accomplished. OUTCOMES: To describe the surgical technique, the main outcome measures of this study are vaginal calipers after revision vaginoplasty as well as ability for sexual intercourse. RESULTS: Thirteen patients presented with vaginal stenosis with a median age of 19 years (range 16-31). All patients had one or more different types of vaginoplasties in their medical history, with a median age at first vaginoplasty of 15 months (0-233). Underlying anatomical conditions were urogenital sinus (n = 8), vaginal agenesis (n = 2), persistent cloacae (n = 2), and cloacal exstrophy (n = 1). The main symptoms were disability of sexual intercourse in 13 patients due to stenotic vaginal tissue. The most frequently performed surgical technique was partial urogenital mobilization with a perineal or lateral flaps (n = 10), followed by bowel vaginoplasty (n = 2), in 1 patient a revision vaginoplasty failed due to special anatomical conditions. In a median follow-up of 11 months, all but one patient presented with physiological vaginal length and width, and normal sexual intercourse in those with a partnership. CLINICAL IMPLICATIONS: Perineal flap with partial urogenital mobilization should be considered as a treatment of choice in severe cases of distal vaginal stenosis and after multiple failed former vaginoplasties, while bowel vaginoplasty should be reserved only for cases of complete cicatrization or high located stenosis of the vagina. STRENGTHS & LIMITATIONS: The strength of this study is the detailed description of several cases while the retrospective character is a limitation. CONCLUSION: In patients after feminizing genital repair, perineal flap with partial urogenital mobilization provides a normal anatomical outcome and allows unproblematic sexual intercourse.

BACKGROUND: The Mayer-Rokitansky-Küster-Hauser syndrome, MRKHS, is a rare (orphan) disease characterized by the aplasia or hypoplasia of the uterus and the vagina. In women's health research, little is known as to how much care provision for patients with MRKHS takes into account their socio-demographic together with their clinical characteristics. This work examines the patients' socio-demographic characteristics, highlighting issues of inappropriate and deficient provision of care. METHODS: The study was carried out as part of the larger TransCareO project and included a group of N=129 MRKHS patients who underwent surgery between 2008 and 2012. Using a specially developed questionnaire, we analyzed MRKHS patients' data found both in the clinical documentation of the Department for Women's Health, University Hospital of Tübingen and the patient surveys of the Center for Rare Genital Malformations (CRGM/ ZSGF). Patients who took part in interviews were compared with non-respondents. RESULTS: Patient respondents and non-respondents did not differ as to the parameters of interest. In most cases, primary amenorrhea was reported as an admission reason. In 24% of patients, a medical intervention (hymenal incision or hormone treatment) already occurred before admission to the Center in Tübingen and proper diagnosis of MRKHS. About one third received in advance inappropriate treatment. During the therapy, more than half of the patients were in a solid partnership. 10% of the family anamneses documented the occurrence of urogenital malformations. CONCLUSIONS: Care provision for MRKHS patients is largely characterized by delayed proper diagnosis and in part, by inappropriate treatment attempts; there are also indications of regional differences. Anamnestic clues such as an asymptomatic amenorrhea or renal abnormalities of unclear origin still fail to result early enough in referral to a center on the basis of suspected MRKHS diagnosis. Urogenital malformations in the family are more common in patients than in the general population. For patients, a wide range of burdens are associated with the diagnosis. Abnormalities compared to their female peers occur, for instance, in the partnership status: MRKHS patients have more rarely a partner.

INTRODUCTION: It is unclear how pelvic floor supporting structures might be affected by the absence of the vagina. It was the aim of this prospective study to analyze the magnetic resonance imaging morphology of pelvic support prior and after a Vecchietti procedure in women suffering Mullerian agenesis (Mayer-Rokitansky-Küster-Hauser syndrome). MATERIAL AND METHODS: 26 women with a diagnosis of Mayer-Rokitansky-Küster-Hauser syndrome associated vaginal agenesis were recruited prospectively prior to the laparoscopic creation of a neovagina according to the Vecchietti procedure. The primary outcome measure was the magnetic resonance imaging morphology of supporting structures. Secondary outcome measures were anatomical and functional vaginal length. Follow up was conducted six months after surgery. RESULTS: Twenty-six women were analyzed. Mean age was 19.8 ± 4.4 years (±SD) and mean body mass index was 23.7 ± 4.3 kg/m2 (±SD). All were Caucasian. Supporting structures consistent with cardinal and uterosacral ligaments were visible on magnetic resonance imaging in all cases (100%). There were no levator ani defects. The vaginal apex could be visualized postoperatively in 12 women (46.2%) reaching up to Level I. The vagina was visible in both Level II and III with normal relations to the pelvic walls in all cases. On gynecological examination, vaginal length was 8.8 ± 2.1 cm (mean ± SD) anatomically and 10.2 ± 2.2 cm (mean ± SD) functionally. CONCLUSIONS: The preoperative presence of pelvic support structures into which the vagina is lengthened by the surgery likely explains the uncommon occurrence of vaginal prolapse in women who had the Vecchietti procedure.

PURPOSE: Several classification systems for female genital tract anomalies exist but are of limited use in clinical practice. We, therefore, assessed the applicability and ease of use of the new ESHRE/ESGE classification, using only patient records. METHODS: This retrospective, single-center, proof-of-principle study systematically analyzed the surgical reports and other hospital records of 920 inpatients and outpatients treated for confirmed female genital tract congenital malformations at a major German university hospital during 2003-2013. Using only this information, a non-expert (medical student) assigned patients to an ESHRE/ESGE class, rating ease of classification based on the time and the number of additional medical records required. Results were verified by an expert gynecologist, who also classified any malformations previously left unclassified. Data analysis used descriptive statistics. RESULTS: The non-expert successfully classified 859/920 patients (93.4%), rating classification as "easy" for 836/859 (90.9%) and "moderately difficult" for 23/859 (2.5%) patients. The expert gynecologist successfully classified 60 (60/920, 6.5%) of the remaining 61 patients rated as "difficult" by the non-expert, but was unable to accurately subclassify 1 patient (1/920, 0.1%) because the operative report lacked the relevant details. 251/920 (27.3%) patients had associated non-Müllerian anomalies, most frequently renal (20.9%) and skeletal (9.1%) malformations. CONCLUSIONS: The ESHRE/ESGE classification provides a generally applicable, comprehensive, and adequately specific classification of female genital tract congenital malformations. It offers an efficient basis for communication between non-experts and experts in the field and is, therefore, useful in clinical management and treatment planning.

The purpose of this study was to assess the impact of disseminated tumor cells (DTCs) on progression-free and overall survival (OS) in patients with metastatic breast cancer (MBC) and to compare it to simultaneous detection of circulating tumor cells (CTCs) from the blood in a subgroup. Disseminated tumor cells were identified in bone marrow (BM) aspirates by immunocytochemistry (pancytokeratin antibody A45-B/B3) and cytomorphology prior to the beginning of a new-line therapy. CTCs were enumerated by the CellSearch® technology. BM was obtained from 178 patients with MBC; 64/178 (36 %) patients were DTC-positive. Disseminated tumor cells occurred more frequently in patients with visceral metastases (p = 0.020) and ≥2 lines of therapy (p = 0.017). CTCs were assessed in 33 of these patients and 17/33 (52 %) patients had CTC counts ≥5 CTCs/7.5 ml blood. There was no significant association between the DTC and CTC status. Univariate analysis revealed DTC detection as a significant predictor of poor OS (p < 0.001); median OS in DTC-negative versus DTC-positive patients was 52 [95 % confidence interval (CI) 38-67] versus 28 [95 % CI 19-37] months. Moreover, as described previously, patients with ≥5 CTCs/7.5 ml blood were at an increased risk of disease progression (p = 0.026) and death (p = 0.025). Disseminated tumor cells are predictors of poor prognosis in MBC, highlighting the role of tumor cell dissemination into the BM for breast cancer progression. The absence of a significant association between concurrent DTCs and CTCs suggests they might represent different aspects of systemic BC spread.

Gold-phosphido-monolayer-protected clusters (MPCs) of 1-2-nm diameter, Au(x)(PR2)y, analogues of the well-known thiolate materials Au(x)(SR)y, were prepared by NaBH4 reduction of a mixture of HAuCl4.3H2O and a secondary phosphine PHR2 in tetrahydrofuran/water. In comparison to the Au-thiolate MPCs, fewer of the larger phosphido groups are required to cover the surface, and the Au-P bond is not cleaved as readily in reactions with small molecules as is its Au-S counterpart. 31P NMR spectroscopy provides a direct method to study cluster formation and the interaction of the phosphido ligand with the gold surface.

A diphenylacetylene containing two different end groups (isonitrile and thioacetate) was synthesized, showing that the chemistry used to install each end group is compatible with that of the others. The isonitrile group binds preferentially to platinum, and the thiol group binds preferentially to gold. However, the selectivity was different when nanoparticles were compared to planar substrates.
RESUMEN
Deprotonation of the phosphine complexes Au(PHR(2))Cl with aqueous ammonia gave the gold(I) phosphido complexes [Au(PR(2))](n)() (PR(2) = PMes(2) (1), PCy(2) (2), P(t-Bu)(2) (3), PIs(2) (4), PPhMes (5), PHMes (6); Mes = 2,4,6-Me(3)C(6)H(2), Is = 2,4,6-(i-Pr)(3)C(6)H(2), Mes = 2,4,6-(t-Bu)(3)C(6)H(2), Cy = cyclo-C(6)H(11)). (31)P NMR spectroscopy showed that these complexes exist in solution as mixtures, presumably oligomeric rings of different sizes. X-ray crystallographic structure determinations on single oligomers of 1-4 revealed rings of varying size (n = 4, 6, 6, and 3, respectively) and conformation. Reactions of 1-3 and 5 with PPN[AuCl(2)] gave PPN[(AuCl)(2)(micro-PR(2))] (9-12, PPN = (PPh(3))(2)N(+)). Treatment of 3 with the reagents HI, I(2), ArSH, LiP(t-Bu)(2), and [PH(2)(t-Bu)(2)]BF(4) gave respectively Au(PH(t-Bu)(2))(I) (14), Au(PI(t-Bu)(2))(I) (15), Au(PH(t-Bu)(2))(SAr) (16, Ar = p-t-BuC(6)H(4)), Li[Au(P(t-Bu)(2))(2)] (17), and [Au(PH(t-Bu)(2))(2)]BF(4) (19).
