Presentation
Renal tubular acidosis presenting as respiratory paralysis. Neurol India 2010: 58: 106-108. 7. Sanyal D, Bhattacharjee S. Thyrotoxic hypokalemic periodic paralysis as the presenting symptom of silent thyroiditis. [neurologyindia.com]
[…] feature. [3] Rickets as the presenting feature of Wilson's disease has been reported very rarely. [4] We present a child of 13 years presenting with rickets refractory to replacement of vitamin D due to Fanconi's syndrome secondary to Wilson's disease [ijem.in]
It was observed that all patients presented polyuria, polydipsia and intestinal constipation. Of the five patients, four (1,2,3 and 4) presented unilateral cryptorchidy that was corrected surgically. [bjn.org.br]
We present a case of a young female who presented with proximal RTA and Fanconi syndrome and excellently responded to Vitamin D replacement. [sjkdt.org]
Entire Body System
- Short Stature
Affiliated tissues include kidney and bone, and related phenotypes are short stature and proteinuria [malacards.org]
Thus a diagnosis of short stature and refractory rickets due to Fanconi's syndrome secondary to Wilson's disease was made. [ijem.in]
RFS Classification genetic, renal Phenotypes Autosomal dominant inheritance ; Glycosuria ; Hypokalemia ; Hypophosphatemia ; Lacticaciduria ; Muscle weakness ; Osteomalacia ; Proteinuria ; Renal insufficiency ; Renal tubular dysfunction ; Rickets ; Short [mousephenotype.org]
Other causes of failure to thrive and short stature. Investigations The diagnosis is based on excessive loss of substances in the urine (eg, amino acids, glucose, phosphate, bicarbonate) in the absence of high plasma concentrations. [patient.info]
- Poor Growth
Clinical features include poor growth, fatigue, dehydration, polyuria, muscle weakness, and bone pain. Features on a basic blood panel includes hypokalemia, hypophosphatemia and metabolic acidosis. [radiopaedia.org]
Workup
Urine
- Glycosuria
Our patients (5 women and 2 men) developed renal tubular dysfunction, with hypophosphatemia, normoglycemic glycosuria, proteinuria, and decrease of creatinine clearance. [journals.lww.com]
Glycosuria Glycosuria secondary to proximal tubule dysfunction is another of the cardinal features of Fanconi syndrome and results from impaired tubular reabsorption of glucose. It is often one of the first diagnostic clues. [abdominalkey.com]
[…] type 2 (proximal), hypophosphataemic rickets (children) or osteomalacia (adults), and renal glycosuria. [ 2, 3 ] Epidemiology The incidence of each cause of Fanconi's syndrome is different, although almost all of them are rather rare. [patient.info]
On extensive investigation we documented proximal renal tubular dysfunction in the form of glycosuria, phosphaturia, proteinuria and bicorbonaturia. Liver biopsy also revealed hepatic glycogen accumulation. [omicsonline.org]
Proximal tubular dysfunction, resembling adult Fanconi's syndrome, was suggested by an increased urinary loss of phosphate and urate and glycosuria. [jamanetwork.com]
Treatment
[…] consulted for: Blood In Urine (Hematuria) Treatment, H.I.V, Blood in Urine Dr. [lybrate.com]
Treatment of isotonic saline with electrolyte replacement was maintained. However, the electrolyte imbalance was not corrected, and the metabolic acidosis was aggravated by this treatment. [kjim.org]
Treatment options vary depending on nature of the renal tubular disorder. [amboss.com]
Most of the time, treatment for RTA is effective. Kids whose RTA is caused by a genetic defect may need treatment for the rest of their lives. The good news is that sticking with their treatments lets kids remain healthy. Date reviewed: March 2014 [kidshealth.org]
Prognosis
Syndrome regarding definition, distribution, risk factors, causes, signs & symptoms, diagnosis, complications, treatment, prevention, prognosis, and additional useful information HERE. [dovemed.com]
Prognosis Prognosis depends on the cause of the syndrome and the severity of renal and extrarenal manifestations. Prevention Avoiding exposure to potential toxins - eg, outdated tetracyclines and aminoglycosides. [patient.info]
Prognosis Careful balancing of body chemicals will usually produce good results. If there is an underlying disease responsible for the kidney malfunction, it may be the determining factor in the prognosis. [the-medical-dictionary.com]

Prevention
Currently, there are no methods available to prevent the inherited form of this abnormality It is a difficult and complicated condition that needs urgent and active treatment administration. [dovemed.com]
Dehydration due to polyuria: prevent by ensuring adequate fluid intake; episodes of dehydration require either oral or intravenous fluid replacement. [patient.info]
