Terminal with deletions of the long arm of chromosome 4 are associated with a recognizable phenotype consisting of dysmorphic facial features, cleft the palate, upper and lower limb malformations, cardiac defects and growth and mental retardation. Here we report on two female patients,of a mother and her daughter, carrying the same 4q34-->qter deletion but presenting with a different phenotype. The mother's presentation is phenotype consistent with previous findings in patients with terminal deletions of the long arm of chromosome 4. However, she presented at Here the age of 54years with bilateral serous carcinoma of the Fallopian tubes, a rare gynaecologic cancer that might be attributed long to the haploinsufficiency of the tumor suppressor gene FAT. The daughter presented isolated congenital aplasia of the uterus and vagina,a the prime feature of the MRKH syndrome. This has not been described before in association with a 46,XX,del(4)(q34qter).

The to mammalian female reproductive tract develops from the Mullerian ducts which differentiate, in a cranial to caudal direction, into oviducts, uterine tract horns, cervix and the anterior vagina. The developmental processes taking place during this organogenesis are notably under the control of ducts steroid hormones, such as members of the Wnt and Hox families, which regulate key developmental genes. At later stages, steroid cervix hormones also participate in the development of the female genital tract. Chemical compounds homologous to steroids can thus act as which agonists or antagonists in fetuses exposed to them. These so-called endocrine disruptors are nowadays found in increasing amounts in the from environment and may therefore have a particular impact on such developing organs. Epidemiological studies have revealed that endocrine disruptors have or had drastic effects on female health and fertility during the last decades. Furthermore, these adverse effects might be transmitted to found subsequent generations through epigenetic modifications. Given the potential hazard of inherited epigenetic marks altering reproduction and/or human health, such molecular inherited mechanisms must be urgently investigated. This review aims to summarize the cellular and molecular mechanisms involved in female genital tract potential development, to highlight key genes involved in this process and to present epigenetic mechanisms triggered by endocrine disruptors and their the consequences in regard to female reproductive tract development.

ABSTRACT:for BACKGROUND: Aspergillus fumigatus, a saprophytic mould, is responsible for life-threatening, invasive pulmonary diseases in immunocompromised hosts. The role of the is airway epithelium involves a complex interaction with the inhaled pathogen. Antimicrobial peptides with direct antifungal and chemotactic activities may boost immunocompromised antifungal immune response. RESULTS: The inducible expression of defensins by human bronchial epithelial 16HBE cells and A549 pneumocyte cells exposed chemotactic to A. fumigatus was investigated. Using RT-PCR and real time PCR, we showed an activation of hBD2 and hBD9 defensin in genes: the expression was higher in cells exposed to swollen conidia (SC), compared to resting conidia (RC) or hyphal fragments invasive (HF). The kinetics of defensin expression was different for each one, evoking a putative distinct function for each investigated defensin.between The decrease of defensin expression in the presence of heat-inactivated serum indicated a possible link between defensins and the proteins punctual of the host complement system. The presence of defensin peptide hBD2 was revealed using immunofluorescence that showed a punctual cytoplasmic SC. and perinuclear staining. Quantification of the cells stained with anti hBD2 antibody demonstrated that SC induced a greater number of defensin cells that synthesized hBD2, compared to RC or HF. Labelling of the cells with anti-hBD-2 antibody showed a positive immunofluorescence a signal around RC or SC in contrast to HF. This suggests co-localisation of hBD2 and digested conidia. The HBD2 level expression was highest in the supernatants of cells exposed to SC, as was determined by sandwich ELISA. Experiments using neutralising anti-interleukine-1beta SC. antibody reflect the autocrine mechanism of defensin expression induced by SC. Investigation of defensin expression at transcriptional and post-transcriptional levels that demonstrated the requirement of transcription as well as new protein synthesis during A. fumigatus defensin induction. Finally, induced defensin expression new in primary culture of human respiratory cells exposed to A. fumigatus points to the biological significance of described phenomena. CONCLUSIONS:swollen Our findings provide evidence that respiratory epithelium might play an important role in the immune response during Aspergillus infection. Understanding hBD2 the mechanisms of regulation of defensin expression may thus lead to new approaches that could enhance expression of antimicrobial peptides or for potential therapeutic use during aspergillosis treatment.

A melanoma. 66-year-old woman was diagnosed with vaginal melanoma. Sentinel node mapping was performed using Tc sulfur colloid. Planar scintigraphic acquisitions detected 66-year-old 2 sentinel nodes in the right external iliac region, which were laparoscopically removed with an anterior vaginectomy. Sentinel node mapping woman is feasible in cases of vaginal melanoma.

Introduction mutation McCune-Albright syndrome (MAS) is characterized by peripheral precocious puberty, café-au-lait spots, and polyostotic fibrous dysplasia. This syndrome is due to characterized a post-zygotic mutation of the GNAS1 gene with mosaic distribution and unilateral predominance. Clinical manifestations depend on the tissues carrying café-au-lait the mutation. We describe the ovarian function before and after unilateral ovariectomy in a woman with MAS and bilateral distribution the of the GNAS1 gene mutation. Case report A 33-year-old patient, previously diagnosed as having MAS, presented irregular menstrual cycles (30-180 distribution days) and monophasic temperature curves. Transvaginal ultrasound and blood tests were repeated at 3-day intervals over 3 months. Findings included peripheral a persistent quiescent left ovary, a persistent polycystic right ovary, constantly high estradiol-17beta (E(2)) levels, and very low FSH and intervals LH levels. She also presented severe persistent pelvic pain. Because of unilateral ovarian activity, a unilateral right ovariectomy was performed constantly as well as biopsy of the remaining left ovary. A GNAS1 gene mutation was identified in both ovaries. A regular level monthly menstrual cycle was immediately restored. On day 3 of the menstrual cycle, E(2) level was 30 pg/ml, FSH level menstrual was 7.5 mIU/ml, and LH level was 6.4 mIU/ml. On day 17, pelvic ultrasound showed one follicle of 25 mm cycles in the left ovary. On day 21, the progesterone level was 13.1 ng/ml. Discussion This is the first report of predominance. ovulation being restored following unilateral ovariectomy in an adult patient suffering from severe MAS with GNAS1 gene mutation identified in level both ovaries.

PBX1 during belongs to the TALE-class of homeodomain protein and has a wide functional diversity during development. Indeed, PBX1 is required for TALE-class haematopoiesis as well as for multiple developmental processes such as skeletal patterning and organogenesis. It has furthermore been shown that and PBX1 functions as a HOX cofactor during development. More recent data suggest that PBX1 may act even more broadly by haematopoiesis modulating the activity of non-homeodomain transcription factors. To better understand molecular mechanisms triggered by PBX1 during female genital tract development,More we searched for additional PBX1 partners that might be involved in this process. Using a two hybrid screen, we identified homeodomain a new PBX1 interacting protein containing several zinc finger motifs that we called ZFPIP for Zinc Finger PBX1 Interacting Protein.genital We demonstrated that ZFPIP is expressed in embryonic female genital tract but also in other PBX1 expression domains such as in the developing head and the limb buds. We further showed that ZFPIP is able to bind physically and in vivo head to PBX1 and moreover, that it prevents the binding of HOXA9/PBX complexes to their consensus DNA site. We suggest that the ZFPIP is a new type of PBX1 partner that could participate in PBX1 function during several developmental pathways.

Single DET embryo transfer is the best way to reduce the risk of multiple pregnancy in IVF-intracytoplasmic sperm injection (ICSI). Between June the 2002 and December 2004, all patients (first cycle, female age <38 years) were offered the choice between having one (SET)the or two (DET) embryos transferred. Among 493 couples, 428 had at least two good quality embryos, and among them, 32%and opted for SET. The SET and DET populations were not comparable (patients in the SET group were younger and had at more oocytes retrieved), and therefore a paired, case-control analysis was performed involving 130 SET couples and 130 DET couples, matched way according to the female partners' ages and the numbers of embryos available. All of the SET patients, and 82% of more the DET group, had at least one embryo cryopreserved,(3.9 versus 2.8 embryos). The option of SET was continued for couples the frozen-thawed embryo transfers. The pregnancy rate following embryo transfer was significantly lower after SET compared with DET for both transfer fresh (27.6 versus 36.9%; P < .05) and frozen-thawed (14.4 versus 23.5%) embryos. However, the cumulative live birth rates following following the transfer of fresh and frozen embryos were identical between the two groups (43 versus 45%), with a high prevalence DET of twins following DET (34 versus %).

ABSTRACT:may The Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome refers to the congenital absence or severe hypoplasia of the female genital tract, often described as syndrome uterovaginal aplasia which is the prime feature of the syndrome. It is the second cause of primary amenorrhea after gonadal absence dysgenesis and occurs in ~ 1 in 4500 women. Aetiology of this syndrome remains poorly understood. Frequent association of other which malformations with the MRKH syndrome, involving kidneys, skeleton and ears, suggests the involvement of major developmental genes such as those remains of the HOX family. Indeed mammalian HOX genes are well known for their crucial role during embryogenesis, particularly in axial the skeleton, hindbrain and limb development. More recently, their involvement in organogenesis has been demonstrated notably during urogenital differentiation. Although null mammalian mutations of HOX genes in animal models do not lead to MRKH-like phenotypes, dominant mutations in their coding sequences or axial aberrant expression due to mutated regulatory regions could well account for it. Sequence analysis of coding regions of HOX candidate of genes and of PBX1, a likely HOX cofactor during Mullerian duct differentiation and kidney morphogenesis, did not reveal any mutation of in patients showing various forms of MRKH syndrome. This tends to show that HOX genes are not involved in MRKH suggests syndrome. However it does not exclude that other mechanisms leading to HOX dysfunction may account for the syndrome.

ABSTRACT:account The Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome affects at least 1 out of 4500 women and has for a long time been considered syndrome as a sporadic anomaly. Congenital absence of upper vagina and uterus is the prime feature of the disease which, in 1 addition, is often found associated with unilateral renal agenesis or adysplasia as well as skeletal malformations (MURCS association). The phenotypic considered manifestations of MRKH overlap various other syndromes or associations and thus require accurate delineation. Since MRKH manifests itself in males,unilateral the term GRES syndrome (Genital, Renal, Ear, Skeletal) might be more appropriate when applied to both sexes. The MRKH syndrome,at when described in familial aggregates, seems to be transmitted as an autosomal dominant trait with an incomplete degree of penetrance Since and variable expressivity. This suggests the involvement of either mutations in a major developmental gene or a limited chromosomal deletion.Skeletal) Until recently progress in understanding the genetics of MRKH syndrome has been slow, however, now HOX genes have been shown limited to play key roles in body patterning and organogenesis, and in particular during genital tract development. Expression and/or function defects or of one or several HOX genes may account for this syndrome.

Comparison the between 400 nt of mouse DNA sequence immediately upstream (5') of the coding sequence of the Sertoli cell expressed genes,of Amh and Tsx, identified a 33 nt sequence with a significant identity: this was considered to be a candidate Sertoli immediately specific regulatory element (SSRE). Another highly conserved sequence has been identified immediately downstream (3') of the Amh polyadenylation signal (DSRE).expressed The action and specificity of these two putative regulatory elements, inserted into a reporter vector (pd2EGFP), has been investigated by highly transient transfection of mouse fibroblast and Sertoli cells. When combined together or alone, with a minimal thymidine kinase (Tk) promoter,mouse SSRE showed a weak incremental action on the expression of the reporter gene, regardless of the cell type: in contrast a there was a 2- to 3-fold decrease when DSRE was present. However, in the absence of Tk there was evidence fibroblast for a strong synergy between SSRE and DSRE, which was significantly greater in the Sertoli as compared with the fibroblast the cells. These results support the view that SSRE exhibits a degree of Sertoli specificity and acts synergistically with DSRE in However, controlling the expression of Amh.

OBJECTIVE:relatively To evaluate anatomic and sexual outcomes in women with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome after laparoscopic Davydov (laparoscopic peritoneal vaginoplasty). DESIGN: Prospective and follow-up study of patients with MRKH syndrome after vaginoplasty (Design classification: II-2). SETTING: Academic hospital. PATIENTS: Patients with MRKH syndrome women and frequency-matched age-comparable healthy controls. INTERVENTION: Thirty-one patients with MRKH syndrome underwent surgery with the procedure, and their clinical, surgical,Prospective and follow-up data were recorded. A Female Sexual Function Index (FSFI) questionnaire was administrated to evaluate sexual functions of patients patients who became sexually active and compared them with 50 randomly selected, age-matched healthy women. MEASUREMENTS: FSFI scores in women with outcomes MRKH syndrome and in control subjects. Clinical and anatomic measurements of neovagina. MAIN RESULTS: The laparoscopic Davydov was successfully completed to in all 31 cases, with 24 patients monitored. The mean length of the neovagina was 6.27+/-1.25 cm. There was no with statistical difference in the total FSFI score between the case and control groups. There is indication that shorter neovaginal length,was especially of<7 cm, appears to be associated with lower total FSFI scores. CONCLUSION: Laparoscopic Davydov is a safe, effective treatment cm. of Mayer-Rokitansky-Kuster-Hauser syndrome with minimal invasion and a relatively low complication rate.

ABSTRACT:or BACKGROUND: Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH) consists of congenital aplasia of the uterus and the upper part of vagina due to anomalous (MRKH) development of Mullerian ducts, either isolated or associated with other congenital malformations, including renal, skeletal, hearing and heart defects. This of disorder has an incidence of approximately 1 in 4500 newborn girls and the aetiology is poorly understood. Methods and Results:of we report on two patients affected by MRKH syndrome in which array-CGH analysis disclosed an identical deletion spanning 1.5 Mb girls of genomic DNA at chromosome 17q12. One patient was affected by complete absence of uterus and vagina, with bilaterally normal of ovaries, while the other displayed agenesis of the upper part of vagina, right unicornuate uterus, non cavitating rudimentary left horn of and bilaterally multicystic kidneys. The deletion encompassed two candidate genes, TCF2 and LHX1. Mutational screening of these genes in a uterus selected group of 20 MRKH females without 17q12 deletion was negative. CONCLUSION: Deletion 17q12 is a rare albeit recurrent anomaly was mediated by segmental duplications, previously reported in subjects with developmental kidney abnormalities and diabetes. The present two patients expand the 17q12 clinical spectrum associated with this imbalance and suggest that this region is a candidate locus for a subset of MRKH by syndrome individuals, with or without renal defects.

Magnetic benefits resonance imaging (MRI) is the mainstay in the imaging evaluation of Mullerian agenesis, but is not routinely being utilized, particularly imaging in India. Though sagittal MRI clearly demonstrates the absence or hypoplasia of the uterus and the axial images demonstrate the the normal ovaries, it is the ability to identify and objectively evaluate other associated anomalies that makes MRI a unique diagnostic Mullerian modality. It is also noninvasive and has multiplanar capabilities at the same time having a very high soft tissue resolution.absence We presume it can be used as a comprehensive imaging package for evaluating these patients at one sitting. We report (MRI) a case of Mullarian agenesis presenting as primary amenorrhea stressing the role and benefits of MRI.

Background:sense Utero-vaginal agenesis, also called the Mayer-Rokitansky-Küster-Hauser Syndrome (MRKH), is a congenital abnormality of the female genital tract, characterized by the called non-formation of the vagina and the uterus. It is a common cause of primary amenorrhoea. Little is known about the is psychological impact and management of this condition. Method: We describe a specific model of the core negative psychological impact of of diagnosis and medical treatment of MRKH and a cognitive-behavioural therapy of MRKH based on the model (CBT-MRKH). The Medical Research model Council's (2002) framework for the development and evaluation of complex health interventions was used for intervention development and evaluation. Results:Mayer-Rokitansky-Küster-Hauser Evidence from a recent cross-sectional study and a small randomized controlled trial (RCT) provides preliminary support for the model and for treatment (Heller-Boersma, Schmidt and Edmonds, in press; Heller-Boersma, Schmidt and Edmonds, 2007), and this is further validated by extensive qualitative and material gathered over the course of the RCT from participants. Conclusions: The model and treatment described may also be applicable treatment to a number of other congenital or acquired gynaecological conditions such as premature ovarian failure, breast cancer, early onset endometrial model cancer, female genital mutilation, Turner's Syndrome, ovarian dys/agenesis or, Complete Androgen Insensitivity Syndrome, all of which have a psychological impact therapy not dissimilar to MRKH in terms of these women's sense of self and femininity.

Congenital of absence of uterus and vagina, the Mayer-Rokitansky-Küster-Hauser Syndrome (MRKHS), results from defective müllerian duct development during female embryogenesis; it is uterus the second most common cause of primary amenorrhea. Atypical forms of MRKHS (type B) represent a heterogeneous group of disorders the with associated anomalies of other organ systems which frequently includes the renal and skeletal systems and several individually occurring malformations.duct We report two cases with MRKHS in which we diagnosed situs inversus totalis incidentally during radiologic examinations. Abdominal situs inversus B) describes the mirror-image arrangement of the intra-abdominal organs in the abdominal cavity and it is characterized by the presence of and multiple congenital anomalies. In this report we attempt to question whether the association between MRKHS and situs inversus is a and rare feature of the müllerian dysgenetic spectrum or whether it is the result of random association.

In in this report, our early experience with screening, monitoring and coordinating IVF utilising gestational carrier treatment is described. Although congenital and our iatrogenic etiologies for uterine factor infertility manifest distinctly different reasons for considering a gestational carrier approach, we outline a unified with management strategy for both conditions. One patient had congenital absence of the uterus and proximal vagina (Mayer-Rokitansky-Kuster-Hauser syndrome variant), while treatment another patient presented post-hysterectomy and adjuvant brachytherapy for invasive squamous cervical carcinoma. Conception was established for both patients, the first carrier pregnancies to be achieved using an IVF/gestational carrier technique in Ireland. As demonstrated here, selected patients with at least one early intact ovary who suffer from uterine factor infertility can be excellent candidates for IVF with embryo transfer to a carefully proximal screened gestational carrier. The role of individual and group counselling is reviewed; professional legal advice is prudent in complex cases.post-hysterectomy

OBJECTIVE:and To report a rare Mayer-Rokitansky-Kuster-Hauser (MRKH) anomaly with a septate midline uterus and describe management options. DESIGN: Case report. SETTING:rare Major academic medical center. PATIENT(S): Two adolescent patients presented with pelvic pain and primary amenorrhea. Radiographic imaging showed evidence of a a bicornuate uterus with two uterine horns, cervical hypoplasia, and absence of the upper vagina. INTERVENTION(S): Owing to pain, both Major patients planned laparoscopy with bilateral hemihysterectomies, but in each case laparoscopy showed evidence of a single midline uterus. Continuous hormone absence therapy was used to suppress pain and retrograde menstruation. MAIN OUTCOME MEASURE(S): Uterine preservation and future fertility management. RESULT(S): Given (MRKH) the fertility potential, the treatment plan was to continue hormone therapy until adulthood, when the young woman could select a hormone treatment option for herself. After 2 years, one patient elected hysterectomy at age 18.5 due to persistent pain, while the preservation other patient continues uterine preservation. CONCLUSION(S): We present two cases of a rare and uniquely described anomaly of MRKH with present a single septate midline uterus. We recommend uterine preservation until the age of 18, at which point the patient may preservation. select her treatment option. Novel options include septal resection with subsequent assisted reproductive technology (ART) and cesarean delivery or ART hemihysterectomies, and a gestational carrier.

BACKGROUND:and Primary amenorrhea can be a sign of either delayed puberty or Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. CASE: A virgin 27-year-old woman with amenorrhea pubertal failure, primary amenorrhea, and uterine hypotrophy due to hypogonadotropic hypogonadism sought treatment at our institution. She was diagnosed as a having MRKH syndrome 10 years ago at another institution after pelvic ultrasonography revealed no uterus or ovaries. Unfortunately, no further (MRKH) investigations had been made or treatments implemented during the ensuing decade. SUMMARY AND CONCLUSION: In female patients in whom the hypogonadotropic uterus cannot be visualized with ultrasonography, magnetic resonance imaging and/or laparoscopy should be considered to ensure that the diagnosis is can correct. Besides further imaging, hormonal assessment and breast development should always be initially considered for the diagnosis of delayed puberty another and MRKH syndrome.

OBJECTIVE:morbidity To evaluate the surgical outcome and the long-term anatomic and functional results in young women with Mayer-Rokitansky-Küster-Hauser Syndrome (MRKH) undergoing surgical neovaginal creation with amniotic membranes. DESIGN: Evaluation of surgical and functional outcome according to clinical records and validated questionnaires about long-term sexuality (Female Sexual Function Index [FSFI]) over a 1.5-year follow-up period. SETTING: University hospital and referral center for pediatric and neovaginal adolescent gynecology. PATIENT(S): Seven patients with congenital vaginal aplasia with a mean age of 20.86 +/- 3.56 years (range 17-26 1.5-year years). INTERVENTION(S): McIndoe procedure modified by the application of human freeze-dried amniotic membranes. MAIN OUTCOME MEASURE(S): Anatomic success was defined and by a vaginal length >/=8 cm, and a width allowing the easy introduction of two fingers. FSFI scores were applied years to define functional results. RESULT(S): Mean neovaginal length was 9.3 cm (range 4-12 cm). The mean FSFI score was 30. freeze-dried +/- 6.9. Major operative complications occurred in one patient. In six out of seven patients satisfactory anatomic and functional results Major were achieved. CONCLUSION(S): The surgical dissection of the vesicorectal space and the application of human amnion over a vaginal mold +/- to create a neovagina results in satisfying anatomic and functional outcome with low perioperative morbidity in MRKH patients.
