Disorders of sex development (DSD), ranging in severity from mild genital abnormalities to complete sex reversal, represent a major concern for patients and their families. DSD are often due to disruption of the genetic programs that regulate gonad development. Although some genes have been identified in these developmental pathways, the causative mutations(More)
Disorders of sex development (DSD) are congenital conditions in which chromosomal, gonadal, or phenotypic sex is atypical. Clinical management of DSD is often difficult and currently only 13% of patients receive an accurate clinical genetic diagnosis. To address this we have developed a massively parallel sequencing targeted DSD gene panel which allows us(More)
The Fifth World Congress on Family Law and Children's Rights (Halifax, August 2009) adopted a resolution endorsing a new set of ethical guidelines for the management of infants and children with disorders of sex development (DSD) [www.lawrights.asn.au/index.php?option = com_content&view = article&id = 76&Itemid = 109]. The ethical principles developed by(More)
OBJECTIVES To review the symptoms and lower urinary tract function in women with posthysterectomy vaginal vault prolapse. METHODS A retrospective review was carried out of the urodynamic records of 19 women with posthysterectomy vaginal vault prolapse who had been evaluated in the Bladder Function Laboratory of the Department of Obstetrics and Gynecology(More)
There is increasing interest in fertility and use of assisted reproductive technologies for women with Turner syndrome (TS). Current parenting options include adoption, surrogacy, and spontaneous and assisted reproduction. For women with TS, specific risks of pregnancy include higher than usual rates of spontaneous abortion, foetal anomaly, maternal(More)
PURPOSE To present data on the high rate of SDHB mutations in patients with metastatic pheochromocytoma/paraganglioma whose initial tumor presentation began in childhood or adolescence. PATIENTS AND METHODS From 2000 to 2010, 263 patients with pheochromocytoma/paraganglioma were evaluated through the National Institutes of Health (NIH), Bethesda, MD. Of(More)
OBJECTIVE To determine whether real-time continuous glucose monitoring (CGM) with preset alarms at specific glucose levels would prove a useful tool to achieve avoidance of hypoglycemia and improve the counterregulatory response to hypoglycemia in adolescents with type 1 diabetes with hypoglycemia unawareness. RESEARCH DESIGN AND METHODS Adolescents with(More)
Disorders of sex development (DSD) are congenital conditions where chromosomal, gonad or genital development is atypical. In a significant proportion of 46,XY DSD cases it is not possible to identify a causative mutation, making genetic counseling difficult and potentially hindering optimal treatment. Here, we describe the analysis of a 46,XY DSD patient(More)
OBJECTIVE To determine if rectal and vaginal pressures are clinically equivalent to one another for the purpose of calculating subtracted detrusor pressure during routine filling cystometry and pressure-flow voiding studies. METHODS A total of 140 consecutive filling and voiding cystometrograms were performed at separate sessions on 127 female patients(More)
PURPOSE We show that a novel fragile X-related epigenetic element 2 FMR1 methylation test can be used along with a test for sex-determining region Y (SRY) to provide the option of combined fragile X syndrome and sex chromosome aneuploidy newborn screening. METHODS Fragile X-related epigenetic element 2, SRY, and FMR1 CGG repeat analyses were performed on(More)
