Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare congenital anomaly characterized by complete or partial aplasia of the uterus and the upper part of the vagina. It is reported to be associated with cardiovascular disorders including atrial septal defect, anomalous pulmonary venous return, aortopulmonary window, pulmonary valve stenosis, mitral valve prolapse, tetralogy of Fallot, truncus arteriosus, and patent ductus arteriosus. Herein, for the first time in the medical literature, we present percutaneous closure of an isolated ostium secundum atrial septal defect in this syndrome...

We report a case of adenomyosis which developed from a hypoplastic uterus and leiomyoma in a patient with MRKH syndrome. A 45-year-old Malay female with primary amenorrhoea and primary infertility presented with abdominal mass and abdominal pain. She is phenotypically female, has well developed secondary sexual characteristics, and has normal female external genitalia with shallow vagina dimple. Transabdominal ultrasonography showed a homogenous adnexal mass of 10 × 8 cm, uterus sized 5 × 4 cm, and normal kidneys...

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, also referred to as Müllerian agenesis, is the second most common cause of primary amenorrhea. It is characterized by congenital absence of the uterus, cervix, and the upper part of the vagina in otherwise phenotypically normal 46,XX females. MRKH syndrome has an incidence of about 1 in 4,500-5,000 newborn females and it is generally divided into two subtypes: MRKH type 1, in which only the upper vagina, cervix and the uterus are affected, and MRKH type 2, which is associated with additional malformations generally affecting the renal and skeletal systems, and also includes MURCS (MÜllerian Renal Cervical Somite) characterized by cervico-thoracic defects...

OBJECTIVE: To provide a review of the literature regarding this technique as well as a step-by-step description with the goal of increasing its use as a safe surgical option. Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is characterized by vaginal agenesis and a variety of mullerian duct anomalies. To date, a variety of procedures have been described for creating a neovagina, but the best treatment remains debated. The Wharton-Sheares-George method, a minimally invasive surgical approach for the creation of a neovagina, is remarkably simple to perform...

Klebsiella pneumoniae is the predominant pathogen isolated from liver abscesses of diabetic patients in Asian countries. However, the effects of elevated blood glucose levels on the virulence of this pathogen remain largely unknown. Type 3 fimbriae, encoded by the mrkABCDF genes, are important virulence factors in K. pneumoniae pathogenesis. In this study, the effects of exogenous glucose and the intracellular cyclic AMP (cAMP) signaling pathway on type 3 fimbriae expression regulation were investigated. The production of MrkA, the major subunit of type 3 fimbriae, was increased in glucose-rich medium, whereas cAMP supplementation reversed the effect...

Horizontal gene transfer (HGT), the transmission of genetic material to a recipient that is not the progeny of the donor, is fundamental in bacterial evolution. HGT is often mediated by mobile genetic elements such as conjugative plasmids, which may be in conflict with the chromosomal elements of the genome because they are independent replicons that may petition their own evolutionary strategy. Here we study differences between type 3 fimbriae encoded on wild type plasmids and in chromosomes. Using known and newly characterized plasmids we show that the expression of type 3 fimbriae encoded on plasmids is systematically different, as MrkH, a c-di-GMP dependent transcriptional activator is not needed for strong expression of the fimbriae...

A 17-year-old girl presented with alopecia involving lateral margins of the scalp with primary amenorrhea. There was no history of parental consanguinity, and no other siblings were having similar complaints. Her secondary sexual characters were well developed with hypoplastic vagina. Histopathological findings from scalp biopsy showed features of alopecia areata. Ultrasonography of abdomen and pelvis revealed the absence of uterus and the right kidney. Follicle-stimulating hormone, luteinizing hormone, estradiol, testosterone, and thyroid function test was within normal limits...

The pathogenesis of Klebsiella pneumonia is linked to the bacteria's ability to form biofilms. Mannose-resistant Klebsiella-like (Mrk) hemagglutinins are critical for K pneumonia biofilm development, and the expression of the genes encoding these proteins is activated by a 3',5'-cyclic diguanylic acid (c-di-GMP)-regulated transcription factor, MrkH. To gain insight into MrkH function, we performed structural and biochemical analyses. Data revealed MrkH to be a monomer with a two-domain architecture consisting of a PilZ C-domain connected to an N domain that unexpectedly also harbors a PilZ-like fold...

BACKGROUND: Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome, or the congenital absence of uterus and vagina, is the most severe anomaly of the female reproductive tract. It affects 1 in 5,000 females, and is the second most common cause of primary amenorrhea. The etiology remains unknown in most patients, although four single gene defects and some repetitive copy number variants (CNVs) have been identified. Translocations in MRKH patients are very rare, and reported only in three patients previously without breakpoint mapping...

BACKGROUND: Cases of women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome developing leiomyomata are rare. A case with mitotically active leiomyomata has not previously been described to our knowledge. CASE: A 43-year-old woman with MRKH syndrome found to have an incidental pelvic mass on imaging studies underwent a diagnostic laparoscopy, followed by resection of leiomyomata and uterine remnant via mini laparotomy. Histopathology revealed focal infarction associated with a mitotically active area in one of the leiomyomata but with no evidence of marked cytologic atypia or hypercellularity...

Absence of vagina poses multitude of physical and psychosocial problems in woman's life. 10% of Mayer- Rokitansky-üster-Hauser (MRKH) syndrome patients with high vaginal septum and vaginal atreisa has additional issue of draining uterine cavity. MC Indoe vaginoplasty is universally acceptable and widely practiced procedure for neocolposis reconstruction. Simultaneous reconstruction of vagina with simultaneous continued uterine drainage presents surgical challenge. We offer a simple solution of creating a vaginal mould using a 10 ml disposable syringe, which enables graft application of neovaginal cavity with simultaneous protected uterine drainage per vaginum...

Gonadal dysgenesis and Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) are the most common causes of primary amenorrhoea. Patients with gonadal dysgenesis present with primary amenorrhoea and lack of secondary sexual characteristics, which, in contrast, are present in patients with MRKHS. The coexistence of the 2 syndromes has been reported in only a few studies so far. We describe a case of a 15-year-old girl who presented with short stature and primary amenorrhoea. Investigations revealed hypergonadotropic hypogonadism, and absence of the uterus, and upper two-thirds of the vagina, with presence of the rudimentary lower third of the vagina and non-visualised bilateral ovaries on imaging...

The psychiatric co-morbidities in female population with mullerian agenesis is an area with limited research. This is probably due to the fact that when those patients are diagnosed not much attention or information is given for long term psychiatric follow-up. Owing to their inability to bear children, these subjects often become socially harassed. Thus these constant stressors may lead to development of psychopathology in future. Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a congenital abnormality with absence of uterus, cervix and vagina, but normal secondary sexual characteristics and external genitalia and occurs in every 1 out of 4000-10,000 females...

Biofilm formation is closely related to the pathogenetic processes of Klebsiella pneumoniae, which frequently causes infections in immunocompromised individuals. The immune system of astronauts is compromised in spaceflight. Accordingly, K. pneumoniae, which used to be isolated from orbiting spacecraft and astronauts, poses potential threats to the health of astronauts and mission security. Microgravity is a key environmental cue during spaceflight. Therefore, determining its effects on bacterial biofilm formation is necessary...
