The management of this condition can be done via-improvement of any electrolyte imbalance, as well as, hypertension and anemia treatment as the individuals condition warrants.
Epidemiologically speaking, nephronophthisis, occurs equally in both sexes, and has an estimate 9 in about 8 million rate in individuals. Nephronophthisis is the leading monogenic cause of end-stage renal disease.
Ask-Upmark kidneys are a cause of secondary hypertension that can be curable.
It is thought to be congenital or the consequence of vesicoureteral reflux.
The frequency is unknown, but the disease is considered to be very rare.
Treatment is symptomatic, often addressing indicators associated with peripheral pulmonary artery stenosis. Laryngotracheal calcification resulting in dyspnea and forceful breathing can be treated with bronchodilators including the short and long-acting β2-agonists, and various anticholinergics. Prognosis is good, yet life expectancy depends on the severity and extent of diffuse pulmonary and arterial calcification.
The outcome of Potter's Sequence is poor. A series of 23 patients in 2007 recorded 7 deaths, 4 in the neonatal period. All 16 survivors have chronic kidney disease, with half developing end stage renal failure (median age 0.3 years, range 2 days to 8.3 years). Survivors had growth impairment (44%) and cognitive and motor development delay (25%)
The first child to survive Bilateral Renal Agenesis (BRA), Abigail Rose Herrera Beutler, was born on July 2013 to US Congresswoman Jaime Herrera Beutler.
A few weeks before she was born, Dr. Jessica Bienstock, a professor of maternal-fetal medicine at Johns Hopkins Hospital, administered a series of saline solution injections into the mother's womb to help the baby's lungs to develop. After Abigail was born, the procedure was considered a success. The infant did not need artificial respiration and could breathe on her own. Her parents kept her on kidney dialysis at home until old enough for a kidney transplant. On February 8, 2016, at the age of two, Abigail received a kidney from her father at the Lucile Packard Children's Hospital Stanford in California.
A thorough diagnosis should be performed on every affected individual, and siblings should be studied for deafness, parathyroid and renal disease. The syndrome should be considered in infants who have been diagnosed prenatally with a chromosome 10p defect, and those who have been diagnosed with well defined phenotypes of urinary tract abnormalities. Management consists of treating the clinical abnormalities at the time of presentation. Prognosis depends on the severity of the kidney disease.
While not precisely known, it is estimated that the general rate of incidence, according to Bergsma, for Meckel syndrome is 0.02 per 10,000 births. According to another study done six years later, the incidence rate could vary from 0.07 to 0.7 per 10,000 births.
This syndrome is a Finnish heritage disease. Its frequency is much higher in Finland, where the incidence is as high as 1.1 per 10,000 births. It is estimated that Meckel syndrome accounts for 5% of all neural tube defects there.
Sequence analysis shows that "Pax2" is the only known gene associated with the disease. Mutations in Pax2 have been identified in half of renal coloboma syndrome victims.
Treatment for NPS varies depending on the symptoms observed.
- Perform screening for renal disease and glaucoma, surgery, intensive physiotherapy, or genetic counseling.
- ACE inhibitors are taken to treat proteinuria and hypertension in NPS patients.
- Dialysis and renal transplant.
- Physical therapy, bracing and analgesics for joint pain.
- Other surgery treatments such as patella realignment, joint replacement, and the cutting away of the head of radius.
Meckel syndrome (also known as Meckel–Gruber Syndrome, Gruber Syndrome, Dysencephalia Splanchnocystica) is a rare, , ciliopathic, genetic disorder, characterized by renal cystic dysplasia, central nervous system malformations (occipital encephalocele), polydactyly (post axial), hepatic developmental defects, and pulmonary hypoplasia due to oligohydramnios.
Meckel–Gruber syndrome is named for Johann Meckel and Georg Gruber.
Papillorenal syndrome, also called renal-coloboma syndrome or isolated renal hypoplasia, is an autosomal dominant genetic disorder marked by underdevelopment (hypoplasia) of the kidney and colobomas of the optic nerve.
There are no treatment to return to its normal functions. However, there are treatments for the different symptoms.
For the Developmental symptoms, Educational intervention and speech therapy beginning in infancy could help to reduce the high risk for motor, cognitive, speech, and language delay
For theSkeletal features, referral to an orthopedist for consideration of surgical release of contractures. In addition,early referral to physical therapy could help increase joint mobility.
Lastly, Thyroid hormone replacement could help out the thyroid dysfunction
Since its initial characterization, Potter sequence has been defined into five distinct subclassifications. There are those in the medical and research fields that use the term Potter sequence to specifically refer to only cases of BRA, while other groups use the term to loosely refer to all instances of oligohydramnios and anhydramnios regardless of the specific cause. The assignment of nomenclature to the various causes (types) was employed in order to help clarify these discrepancies, but these subclassifications and nomenclature system have not caught on in the medical and research communities.
Keutel syndrome (KS) is a rare autosomal recessive genetic disorder characterized by abnormal diffuse cartilage calcification, hypoplasia of the mid-face, peripheral pulmonary stenosis, hearing loss, short distal phalanges (tips) of the fingers and mild mental retardation. Individuals with KS often present with peripheral pulmonary stenosis, brachytelephalangism, sloping forehead, midface hypoplasia, and receding chin. It is associated with abnormalities in the gene coding for matrix gla protein (MGP). Being an autosomal recessive disorder, it may be inherited from two unaffected, abnormal MGP-carrying parents. Thus, people who inherit two affected MGP genes will likely inherit KS.
It was first identified in 1972 as a novel rare genetic disorder sharing similar symptoms with chondrodysplasia punctata. Multiple forms of chondrodysplasia punctata share symptoms consistent with KS including abnormal cartilage calcification, forceful respiration, brachytelephalangism, hypotonia, psychomotor delay, and conductive deafness, yet peripheral pulmonary stenosis remains unique to KS.
No chromosomal abnormalities are reported in affected individuals, suggesting that familial consanguinity relates to the autosomal recessive mode of inheritance. Also, despite largely abnormal calcification of regions including the larynx, tracheobronchial tree, nose, pinna (anatomy), and epiglottis, patients exhibit normal serum calcium and phosphate levels.
Fleischer's syndrome is an extremely rare congenital anomaly characterized by displacement of the nipples, occasional polymastia, and hypoplasia of both kidneys.
There is no known cure. In selected patients orthopaedic surgery may be helpful to try to gain some functionality of severely impaired joints.
Urinary tract obstruction as a congenital disorder results in oligohydramnios which in turn can lead to the Potter sequence of atypical physical appearance. Pulmonary hypoplasia is by far the main cause of death in the early neonatal period for children with congenital lower urinary tract obstruction.
Fetal surgery of congenital lower urinary tract obstruction seems to improve survival, according to a randomized yet small study.
Aphalangy, hemivertebrae and urogenital-intestinal dysgenesis is an extremely rare syndrome, described only in three siblings. It associates hypoplasia or aplasia of phalanges of hands and feet, hemivertebrae and various urogenital and/or intestinal abnormalities. Intrafamilial variability is important as one sister had lethal abnormalities (Potter sequence and pulmonary hypoplasia), while her affected brother was in good health with normal psychomotor development at 6 months of age. Prognosis seems to depend mainly on the severity of visceral malformations. Etiology and inheritance remain unknown.
A meta-analysis on the influence of voiding position on urodynamics in healthy males and males with LUTS showed that in the sitting position, the residual urine in the bladder was significantly reduced. The other parameters, namely the maximum urinary flow and the voiding time were increased and decreased respectively. For healthy males, no influence was found on these parameters, meaning that they can urinate in either position.
Sensenbrenner syndrome (OMIM #218330) is a rare (less than 20 cases reported by 2010) multisystem disease first described in 1975. It is inherited in an autosomal recessive fashion, and a number of genes appear to be responsible. Three genes responsible have been identified: intraflagellar transport (IFT)122 (WDR10), IFT43 — a subunit of the IFT complex A machinery of primary cilia, and WDR35 (IFT121: TULP4)
It is also known as Sensenbrenner–Dorst–Owens syndrome, Levin Syndrome I and cranioectodermal dysplasia (CED)
Thymic hypoplasia is a condition where the thymus is underdeveloped or involuted.
Calcium levels can be used to distinguish between the following two conditions associated with thymic hypoplasia:
- 22q11.2 deletion syndrome: hypocalcemia
- Ataxia telangiectasia: normal levels of calcium
In 1988, Goldblatt et al. first reported a 4-year-old boy with hypoplastic patellae, mental retardation, scrotal hypoplasia, skeletal deformities, renal anomalies, flattened nasal bridge, and short stature. Later in 2000, Cormier-Daire et al. reported seven patients with genital anomalies (scrotal hypoplasia and cryptorchidism in the boys and clitoral hypertrophy in the girls), facial dysmorphism, renal anomalies, absent patella, and severe mental retardation in the two survivors. The condition is now known as genitopatellar syndrome.
The outcome of this disease is dependent on the severity of the cardiac defects. Approximately 1 in 3 children with this diagnosis require shunting for the hydrocephaly that is often a consequence. Some children require extra assistance or therapy for delayed psychomotor and speech development, including hypotonia.
