AIM: Posterior urethral valves (PUVs) are the most common cause of congenital bladder outlet obstruction (BOO) in boys and end-stage renal failure (ESRF) in childhood. In the 1980s, 1 in 4000 boys had PUV. Presentation was 1/3 antenatal/neonatally, 1/3 postnatal, 1/3 late (>1 year). This study aimed to describe the current proportions in a contemporary cohort. METHODS: A national audit (BAPS CASS) of referrals in the UK and Ireland of boys diagnosed with suspected or confirmed PUV in a year was conducted...

Introduction: Wolcott-Rallison syndrome (WRS) is a rare, autosomal recessive disorder with infancy-onset diabetes mellitus, multiple epiphyseal dysplasia, osteopenia, mental retardation or developmental delay, and hepatic and renal dysfunction as main clinical findings. Cardiovascular system is very rarely affected and there are a limited number of publications where WRS is associated with congenital heart disease. The aim of this interesting case is to report an infant with Wolcott - Rallison syndrome, type I diabetes mellitus, and complex congenital heart disease, diagnosed in a pre term neonate...

Renal artery stenosis is a common cause of secondary hypertension and chronic kidney disease. We present here a case of fibromuscular dysplasia that was treated with surgical revascularization, resulting in recovery of kidney function with eventual cessation of chronic dialysis. The case involves a 25-year-old female with coincidentally discovered hypertension, who underwent further investigations revealing a diagnosis of renal artery stenosis due to fibromuscular dysplasia. She subsequently developed two episodes of malignant hypertension, with flash pulmonary oedema and worsening renal failure that resulted in dialysis dependence...

Fibromuscular dysplasia (FMD) is a non-atherosclerotic disease that generally affects medium-sized arteries. The distribution typically involves the renal, extracranial carotid/vertebral, and iliac arteries. FMD in other vascular beds is rare. We herein present the case of a 47-year-old female with rapid-onset bilateral digital ischemia. Initial differential diagnosis included vasospastic disorders and vasculitis. An upper extremity arteriogram was suggestive of ulnar and radial FMD. Percutaneous intervention was not successful, and the patient was managed conservatively with symptomatic improvement...

Background: Mainzer-Saldino syndrome (MZSDS) is a skeletal ciliopathy and part of the short-rib thoracic dysplasia (SRTD) group of ciliary disorders. The main characteristics of MZSDS are short limbs, mild narrow thorax, blindness, and renal failure. Thus far, variants in two genes are associated with MZSDS: IFT140, and IFT172 . In this study, we describe a 1-year-old girl presenting with mild skeletal abnormalities, Leber congenital amaurosis, and bilateral hearing difficulties. For establishing an accurate diagnosis, we combined clinical, molecular, and functional analyses...

Renal artery stenosis commonly manifests with hypertension refractory to medical treatment. We report a case of renal artery stenosis occurring in a 19-year-old female patient who presented with extremely high blood pressure and bilateral renal stenosis at the duplex ultrasound. Renal angiography confirmed the bilateral and irregular stenosis due to fibromuscular dysplasia, associated to extent collaterals suppling the poststenotic right renal artery. Therefore, angioplasty with drug-eluting balloon was performed in order to obtain a good vessel patency and to improve patency in the long term follow-up...

The pathophysiology of spontaneous coronary artery dissection (SCAD) is heterogeneous, associated with systemic arteriopathies and inflammatory diseases, and often compounded by environmental precipitants, genetics, or stressors. However, the frequency of these associated conditions with SCAD on a population level remains unknown. Therefore, the objective of this analysis was to evaluate heterogeneous phenotypes of SCAD in the United States using data from the Nationwide Inpatient Sample collected from January 1, 2004, to September 31, 2015...

There is a wide variety of congenital syndromes that can involve the temporal bone. Many of these have overlapping features due to common embryologic abnormalities, such as first and second branchial anomalies. Diagnostic imaging is often important in the workup of hearing deficits related to congenital syndromes. This article reviews the imaging features of selected congenital syndromes with temporal bone abnormalities, including Treacher Collins syndrome, oculo-auriculo-vertebral dysplasia spectrum, Klippel-Feil syndrome, branchio-oto-renal syndrome, Pierre Robin sequence, CHARGE syndrome, Pendred syndrome, Down syndrome, Trisomy 18, Turner syndrome, and neurofibromatosis type 2...

OBJECTIVE: Galloway-Mowat syndrome (GAMOS) is a neural and renal disorder, characterized by microcephaly, brain anomalies, and early-onset nephrotic syndrome. Biallelic mutations in WDR73 and the four subunit genes of the KEOPS complex are reported to cause GAMOS. Furthermore, an identical homozygous NUP107 (nucleoporin 107 kDa) mutation was identified in four GAMOS-like families, although biallelic NUP107 mutations were originally identified in steroid-resistant nephrotic syndrome. NUP107 and NUP133 (nucleoporin 133 kDa) are interacting subunits of the nuclear pore complex in the nuclear envelope during interphase, and these proteins are also involved in centrosome positioning and spindle assembly during mitosis...

Background: Seminal vesicle cyst is an extremely rare condition, which is frequently congenital and associated with Zinner's syndrome. This syndrome represents a constellation of seminal vesicle cyst, ipsilateral or contralateral renal agenesis or renal dysplasia, ureteral ectopia, and ejaculatory duct obstruction. We report a young symptomatic patient undergoing robot-assisted laparoscopic excision of a huge seminal vesicle cyst during which an atrophic ipsilateral kidney was discovered incidentally and managed by nephroureterectomy in the same session without changing trocar positions...

Fibromuscular dysplasia (FMD) mainly develops in medium-sized arteries, including renal, extracranial, and extremity arteries, but it rarely causes abdominal aortic aneurysm (AAA). A 69-year-old woman with AAA diagnosed on ultrasonography by a home doctor visited our hospital. Contrast-enhanced computed tomography revealed a saccular aneurysm of terminal abdominal aorta. We performed abdominal aortic replacement and resected the section with aneurysm. Pathological examination of the wall tissue of the resected aneurysm revealed findings that are consistent with FMD...

This study aimed to demonstrate that prenatal dexamethasone exposure (PDE) can induce kidney dysplasia in utero and adult glomerulosclerosis in male offspring, and to explore the underlying intrauterine programming mechanisms. Pregnant rats were subcutaneously administered dexamethasone 0.2 mg/kg.d from gestational day (GD) 9 to GD20. The male fetus on GD20 and the adult offspring at age of postnatal week 28 were analyzed. The adult offspring kidneys in the PDE group displayed glomerulosclerosis, elevated levels of serum creatinine and urine protein, ultrastructural damage of podocytes, the reduced expression levels of podocyte marker genes, nephrin and podocin...

Ciliopathies-are widely recognized and associated with a wide variety of developmental and degenerative disorders. Most cilia-related diseases have renal manifestation, and there is a cross- overlapping relationship between gene mutations and cilia disease. Here, we investigated the clinical and pathological manifestation of a rare disease patient. We present the case of a 15-year-old child with dysplasia and multiple-organ damage who was initially diagnosed with nephrotic syndrome. The patient's kidney disease progressed to renal failure and received hemodialysis 10 months after renal biopsy...
