Recurrent urinary tract infections (rUTI) in women is a common cause of morbidity worldwide. In young women recurrent cystitis associated with sexual intercourse is quite common; however not all sexually active women will suffer a post-coital UTI episode. A variety of possible predisposing factors has been described, including behavioral risk patterns, genetic factors and increased virulence of certain subtypes of uropathogens. It has long been regarded that anatomical anomalies are rare in this setting of rUTIs...

Objective: Epididymo-orchitis (EO) is a well-known complication of urinary tract infections (UTI) in children. This is commonly seen in children who had hypospadias repair or in those who had surgery for anorectal malformation especially when it results in urethral stricture. However EO occurring as a complication of urethral stricture in adults operated for hypospadias in childhood is not well documented in the literature. Material and methods: This is a retrospective review of four adults who had proximal hypospadias repair in childhood...

PURPOSE: Hypospadias is a common developmental anomaly of the male external genitalia. In previous studies conducted on West European, Californian, and Han Chinese populations the relationship between polymorphic variants of the diacylglycerol kinase kappa (DGKK) gene and hypospadias have been reported. The aim was to study the possible associations between polymorphic variants of the DGKK gene and hypospadias using an independent sample of the Polish population. MATERIALS AND METHODS: Ten single nucleotide polymorphisms in DGKK, which were reported to have an impact on the risk of hypospadias in other populations, were genotyped using high-resolution melting curve analysis in a group of 166 boys with isolated anterior (66%) and middle (34%) forms of hypospadias and 285 properly matched controls without congenital anomalies...

X-linked Opitz G/BBB syndrome (XLOS) is a multisystemic congenital condition, caused by mutations in the midline-1 gene ( MID1 ), characterized by a large inter- and intrafamilial phenotypic variability and often associated with intellectual disability (ID). We report clinical, genetic, and molecular findings in 4 patients with typical XLOS dysmorphic features belonging to 2 unrelated families. Two novel pathogenic loss-of-function MID1 variants, a maternally inherited c.1656del and a de novo c.1215_1228dup, were identified...

INTRODUCTION: There are limited data about pain patterns, analgesic requirements and factors predicting opioid requirements of children undergoing outpatient urologic surgery. This prospective study aimed to assess recovery profiles and pain medication requirements. METHODS: Patients between 6 months and 12 years of age were recruited prospectively between December 2013 and June 2014. Demographic and operative characteristics were collected. Following discharge home, the parents were asked to administer both acetaminophen and ibuprofen Q6H at a weight-adjusted dose, based on a schedule, until the end of postoperative day 2, and to administer the medication as required on postoperative day 3...

Androgens have an extensive influence on brain development in regions of the brain that are relevant for autism spectrum disorder (ASD), yet their etiological involvement remains unclear. Hypospadias (abnormal positioning of the urethral opening) and cryptorchidism (undescended testes) are 2 relatively common male birth defects that are strongly associated with prenatal androgen deficiencies. Having either disorder is a proxy indicator of atypical gestational androgen exposure, yet the association between these disorders and autism has not been extensively studied...

Autism spectrum disorder (ASD) is a prevalent developmental disorder. Studies indicate that while ASD etiology has a genetic component, the risk is polygenic, with gene-environment interactions being likely. The prenatal period is a critical exposure window for nongenetic risk factors. Previous studies have found positive associations between congenital malformations (all types) and ASD; a few also found specific associations between genitourinary system malformations and ASD; and one study found an association between hypospadias and ASD...

PURPOSE: Our study objective is to examine the association between births conceived with assisted reproductive technology (ART) and birth defects using a large database from the United States. METHODS: Using the Centers for Disease Control and Prevention's Period-linked birth-infant death data files and fetal death database for 2011-2013, we conducted a retrospective cohort study comprised of live births that occurred in the USA during that time. Multivariate logistic regression was used to estimate the association between ART and birth defects, both overall and by specific defects...

Myelin Regulatory Factor (MYRF) is a transcription factor that has previously been associated with the control of the expression of myelin-related genes. However, it is highly expressed in human tissues and mouse embryonic tissues outside the nervous system such as the stomach, lung, and small intestine. It has not previously been reported as a cause of any Mendelian disease. We report here two males with Scimitar syndrome [MIM 106700], and other features including penoscrotal hypospadias, cryptorchidism, pulmonary hypoplasia, tracheal anomalies, congenital diaphragmatic hernia, cleft spleen, thymic involution, and thyroid fibrosis...

We report a 4-month-old male proband with a history of prominent forehead, hypertelorism, ear abnormalities, micrognathia, hypospadias, and multiple cardiac abnormalities. Initial microarray analysis detected a concurrent 7p21.3-p22.3 duplication and 13q33.2-q34 deletion indicating an unbalanced rearrangement. However, subsequent conventional cytogenetic studies only revealed what appeared to be a balanced t(12;20)(q24.33;p12.2). Fluorescence in situ hybridization (FISH) using chromosome-specific subtelomere probes confirmed the presence of an unbalanced der(13)t(7;13)(p21...

Human 3 beta-hydroxysteroid dehydrogenase deficiency (3b-HSD) is a very rare form of congenital adrenal hyperplasia resulting from HSD3B2 gene mutations. Its estimated prevalence is less than 1/1,000,000 male neonates. It leads to steroidogenesis impairment in both adrenals and gonads. Few data are available on adult testicular function in such patients. Therefore, we evaluated gonadal axis and testicular function in a 46,XY adult patient, carrying a HSD3B2 mutation. The patient presented at birth with neonatal salt wasting syndrome, a micropenis, perineal hypospadias and intrascrotal testes...

INTRODUCTION: Fetal valproate syndrome was first described in 1984. Valproic acid crosses the placenta and can potentially lead to major congenital malformation, dysmorphism and neurodevelopmental disorder. METHODS: A retrospective study of 29 cases of FVS diagnosed by geneticists from 1995 to 2016. The cases were diagnosed based on criteria of fetal anticonvulsant syndrome. RESULTS: A total of 29 cases reported in the last 21 years. Features commonly described are prominent metopic ridge, midface hypoplasia, epicanthic folds, micrognathia and broad and flat nasal bridge...

BACKGROUND: Disorders of sex development (DSD) have an estimated frequency of 0.5% of live births encompassing a variety of urogenital anomalies ranging from mild hypospadias to a discrepancy between sex chromosomes and external genitalia. In order to identify the underlying genetic etiology, we had performed exome sequencing in a subset of DSD cases with 46,XY karyotype and were able to identify the causative genetic variant in 35% of cases. While the genetic etiology was not ascertained in more than half of the cases, a large number of variants of unknown clinical significance (VUS) were identified in those exomes...

SOX2 variants have been identified in multiple patients with severe ocular anomalies and pituitary dysfunction, in addition to various systemic features. We investigated a 26-year-old female patient suffering from spastic paraparesis, hypoplasia of corpus callosum, hypogonadotropic hypogonadism (HH) and intellectual disability, who was monitored for over 20 years, allowing a detailed genotype-phenotype correlation along time. Whole exome sequencing on the patient and her relatives identified a de novo SOX2 c...
