Primary carnitine deficiency is a disorder of fatty acid oxidation caused by mutations in the Na+-dependent carnitine/organic cation transporter OCTN2. Studies with tyrosyl group-modifying reagents support the involvement of tyrosine residues in Na+ binding by sodium-coupled transporters. Here we report two new patients with carnitine deficiency caused by(More)
OBJECTIVES To compare the efficacy and safety of tamsulosin and silodosin in the context of medical expulsive therapy (MET) of distal ureteric stones. PATIENTS AND METHODS Observational data were collected retrospectively from patients who received silodosin (N = 50) or tamsulosin (N = 50) as MET from January 2012 to January 2013. Inclusion criteria were:(More)
Velaglucerase alfa is a glucocerebrosidase produced by gene activation technology in a human fibroblast cell line (HT-1080), and it is indicated as an enzyme replacement therapy (ERT) for the treatment of Gaucher disease type 1 (GD1). This multicenter, open-label, 12-month study examined the safety and efficacy of velaglucerase alfa in patients with GD1(More)
Glutaric acidemia type 1 (GA-1) is an autosomal recessive disorder of lysine, hydroxylysine, and tryptophan metabolism. Patients may present with brain atrophy, macrocephaly, and acute dystonia secondary to striatal degeneration typically triggered by an infection, fever, and/or dehydration. This disorder is identified on expanded newborn screening by(More)
Without intervention, classic galactosemia is a potentially fatal disorder in infancy. With the benefit of early diagnosis and dietary restriction of galactose, the acute sequelae of classic galactosemia can be prevented or reversed. However, despite early and lifelong dietary treatment, many galactosemic patients go on to experience serious long-term(More)
Creatine is a nitrogen containing compound that serves as an energy shuttle between the mitochondrial sites of ATP production and the cytosol where ATP is utilized. There are two known disorders of creatine synthesis (both transmitted as autosomal recessive traits: arginine: glycine amidinotransferase (AGAT) deficiency; OMIM 602360; and guanidinoacetate(More)
Published mutations in deoxyguanosine kinase (DGUOK) cause mitochondrial DNA depletion and a clinical phenotype that consists of neonatal liver failure, nystagmus and hypotonia. In this series, we have identified 15 different mutations in the DGUOK gene from 9 kindreds. Among them, 12 have not previously been reported. Nonsense, splice site, or frame-shift(More)
X-linked cerebral creatine deficiency is caused by the deficiency of the creatine transporter encoded by the SLC6A8 gene. Here, we report two half-brothers with this condition and characterize creatine transport in human fibroblasts. The propositus presented at 6 months of age with delays in development and slow progress since then with no regression.(More)
BACKGROUND Extracorporeal shock wave therapy (ESWT) is a conservative therapy for patients with Peyronie's disease (PD). OBJECTIVE To investigate the effects of ESWT in patients with PD. DESIGN, SETTING, AND PARTICIPANTS One hundred patients with a history of PD not >12 mo who had not had previous PD-related treatments were enrolled in a prospective,(More)
Activating mutations of FGFR3, a negative regulator of bone growth, are well known to cause a variety of short-limbed bone dysplasias and craniosynostosis syndromes. We mapped the locus causing a novel disorder characterized by camptodactyly, tall stature, scoliosis, and hearing loss (CATSHL syndrome) to chromosome 4p. Because this syndrome recapitulated(More)
