We report the case of a 20-year-old male Caucasian patient with diagnosed nephrocalcinosis and a medical history of seizures and recurrent urinary tract infections. Laboratory investigations revealed clinical and biochemical abnormalities characteristic of familial hypomagnesemia with hypercalciuria
Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is an autosomal recessive syndrome that affects the tight junction proteins claudin-16 and claudin-19 in the thick ascending limb. In patients with claudin-19 mutations, additional symptoms such as visual impairment and other
BACKGROUND
The cardinal characteristics of primary hypomagnesaemia-hypercalciuria-nephrocalcinosis include renal magnesium wasting, marked hypercalciuria, renal stones, nephrocalcinosis, a tendency towards chronic renal insufficiency and sometimes even ocular abnormalities or hearing
Familial hypomagnesemia and hypercalciuria with nephrocalcinosis is a rare autosomal recessive disease characterized by renal calcium and magnesium wasting, evolving in the progressive decrease of renal function, eventually requiring kidney transplant. Clinical findings include urinary infection,
Hypophosphatasia (HPP) is a rare metabolic disease with the hallmark finding of deficient serum tissue nonspecific alkaline phosphatase (TNSALP) activity. TNSALP is primarily known for its role in mineralization; hence, HPP is characterized by defective mineralization of bone and/or teeth. TNSALP is

Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare autosomal recessive tubular disorder that is frequently associated with progressive renal failure. The primary defect is related to impaired tubular reabsorption of magnesium (Mg) and calcium (Ca) in the thick
UNASSIGNED
Adults treated with topiramate may develop nephrolithiasis, but its frequency in children on topiramate is unknown. Topiramate inhibits renal carbonic anhydrase, which can lead to renal tubular acidosis and hypercalciuria. We studied 40 consecutive children who initiated topiramate
Pyridoxine-responsive seizures (PRS) and the role of pyridoxine (PN, vitamin B(6)) in hypophosphatasia (HPP) are incompletely understood. Typically, PRS and HPP are rare, independent, metabolic disorders. In PRS, seizures resist standard anticonvulsants apart from PN, yet have a good prognosis. In
BACKGROUND
Hypoparathyroidism is characterised by hypocalcaemia, and standard management is with an active vitamin D analogue and adequate oral calcium intake (dietary and/or supplements). Little is described in the literature about the impact of intercurrent illnesses on calcium homeostasis in
BACKGROUND
Hypoparathyroidism is a rare pediatric endocrine disease, which is caused by low circulating levels of PTH or insensitivity to its action in the target tissues.
OBJECTIVE
To report the clinical and biochemical characteristics and theoutcome of 8 patients with
Pseudohypoparathyroidism (PHP) is a rare inherited syndrome with several types. We reviewed the cases of 7 PHP patients seen between 1990 and 2003, and analyzed their clinical, biochemical data and long-term medical outcomes. Six boys and one girl were included. Two siblings showed Albright's
Objective: To study the clinical characteristics of primary hypoparathyroidism in adults. Methods: The clinical data of 200 cases with adult-onset primary hypoparathyroidism in Peking Union Medical College Hospital during December 1987 to December 2015 were collected and analyzed retrospectively.
BACKGROUND
Recent identification and characterization of novel renal Mg(2+) transporters and ion channels have greatly increased our understanding of the normal physiology of renal magnesium handling.
METHODS
The present study deals with the clinical and molecular characterization of eight Turkish
BACKGROUND
The Turkish Renal Tubular Disorders Working Group aimed to form a patient registry database and gathered demographic, clinical, and laboratory data in various hereditary renal tubular disorders (HRTDs).
METHODS
A questionnaire comprising HRTDs was sent to the centers. The cohort was
