OBJECTIVE To determine the frequency of mitochondrial DNA depletion syndrome (MDS) in infants with cholestasis and liver failure and to further clarify the clinical, biochemical, radiologic, histopathologic, and molecular features associated with MDS due to deoxyguanosine kinase (DGUOK) and MPV17 gene mutations. STUDY DESIGN We studied 20 infants with(More)
Mitochondrial DNA (mtDNA) depletion syndromes (MDS) are severe autosomal recessive disorders associated with decreased mtDNA copy number in clinically affected tissues. The hepatocerebral form (mtDNA depletion in liver and brain) has been associated with mutations in the POLG, PEO1 (Twinkle), DGUOK and MPV17 genes, the latter encoding a mitochondrial inner(More)
BACKGROUND/AIM We report our experience with the use of octreotide as primary or adjunctive therapy in children with various gastrointestinal disorders. PATIENTS AND METHODS A pharmacy database identified patients who received octreotide for gastrointestinal diseases. Indications for octreotide use, dosing, effectiveness, and adverse events were evaluated(More)
BACKGROUND & AIMS Proprotein convertase 1/3 (PC1/3) deficiency, an autosomal-recessive disorder caused by rare mutations in the proprotein convertase subtilisin/kexin type 1 (PCSK1) gene, has been associated with obesity, severe malabsorptive diarrhea, and certain endocrine abnormalities. Common variants in PCSK1 also have been associated with obesity in(More)
Herpes simplex virus is a common cause of ulcerative esophagitis in the immunocompromised or debilitated host. Despite a high prevalence of primary and recurrent Herpes simplex virus infection in the general population, Herpes simplex virus esophagitis (HSVE) appears to be rare in the immunocompetent host. We report three cases of endoscopically-diagnosed(More)
Bleeding per rectum is an uncommon presentation in pediatric patients. Heterotopic gastric mucosa in the rectum is a rare cause of rectal bleeding. Here, we report a 3-year-old child with a bleeding rectal ulcer that was initially diagnosed and managed as a solitary rectal ulcer syndrome. After 1 month, the patient persisted to have intermittent rectal(More)
The mutation γ375Arg → Trp (fibrinogen Aguadilla) is one of four mutations (Brescia, Aguadilla, Angers, and AI duPont) capable of causing hepatic storage of fibrinogen. It has been observed in four children from the Caribbean, Europe, and Japan, suffering from cryptogenic liver disease. We report the first case of hepatic fibrinogen storage disease in Arabs(More)
BACKGROUND The Prevalence of liver disease among diabetics has been estimated to be between 17% and 100%. Most of these data were obtained from adult studies. The aim of our study was to screen for liver disease among type 1 diabetic children. METHODS Children with type 1 diabetes following in clinic have been examined for existence of liver disease, from(More)
PiZZ alpha-1-antitrypsin deficiency is the commonest genetic cause of chronic liver disease, but only 10-15% of PiZZ individuals develop liver disease in childhood. Studies have demonstrated varying patterns of disease progression within siblings with the PiZZ phenotype. We retrospectively analysed the case-notes of all patients diagnosed with PiZZ A1ATD(More)
The accidental ingestion of a foreign body is a common problem in children, but ingestion of magnets is rare. When multiple magnets are ingested, they may attract each other and cause pressure necrosis through the bowel walls and eventually lead to serious complications like obstruction, perforation, and fistula formation. We report a case of a 5-year-old(More)
