Wolfram Syndrome-2, a Cause of Severe Gastrointestinal Bleeding: A Case Series and a Literature Review.

Background: There are very few reports of Wolfram syndrome-2 (WFS2) in the literature, and understanding of involvement of the gastrointestinal (GI) tract in the syndrome is limited. Objectives: This study aims to describe the clinical presentations of a large number of WFS2 patients with specific focus on their GI manifestations.

Methods: This is a retrospective case series study.

RIPK1 mutations causing infantile-onset IBD with inflammatory and fistulizing features.

Purpose: Receptor-interacting serine/threonine-protein kinase 1 RIPK1) is an important regulator of necroptosis and inflammatory responses. We present the clinical features, genetic analysis and immune work-up of two patients with infantile-onset inflammatory bowel disease (IBD) resulting from mutations.

Methods: Whole exome and Sanger sequencing was performed in two IBD patients.

Homozygous variant in MADD, encoding a Rab guanine nucleotide exchange factor, results in pleiotropic effects and a multisystemic disorder.

Rab proteins coordinate inter-organellar vesicle-mediated transport, facilitating intracellular communication, protein recycling, and signaling processes. Dysfunction of Rab proteins or their direct interactors leads to a wide range of diseases with diverse manifestations. We describe seven individuals from four consanguineous Arab Muslim families with an infantile-lethal syndrome, including failure to thrive (FTT), chronic diarrhea, neonatal respiratory distress, variable pituitary dysfunction, and distal arthrogryposis.

Hematopoietic stem cell transplantation for mitochondrial neurogastrointestinal encephalopathy: A single-center experience underscoring the multiple factors involved in the prognosis.

Background: Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a progressive autosomal recessive disorder characterized by cachexia, gastrointestinal (GI) dysmotility, ptosis, peripheral neuropathy, and brain magnetic resonance imaging (MRI) white matter changes. Bi-allelic TYMP mutations lead to deficient thymidine phosphorylase (TP) activity, toxic accumulation of plasma nucleosides (thymidine and deoxyuridine), nucleotide pool imbalances, and mitochondrial DNA (mtDNA) instability. Death is mainly due to GI complications: intestinal perforation, peritonitis, and/or liver failure.

Palestinian doctors' views on patient-centered care in hospitals.

Background: Understanding the perceived importance of Patient-Centered Care (PCC) among Palestinian doctors and how the provider and other clinical characteristics may impact their views on PCC is essential to determine the extent to which PCC can be implemented. This study investigates the provision of PCC among hospital doctors in a developing and unstable country, namely, Palestine.

Methods: This descriptive, cross-sectional research employed self-report survey among 369 Palestinian doctors working in hospitals in 2016.

Organic solute transporter-β (SLC51B) deficiency in two brothers with congenital diarrhea and features of cholestasis.

Unlabelled: Primary bile acid malabsorption is associated with congenital diarrhea, steatorrhea, and a block in the intestinal return of bile acids in the enterohepatic circulation. Mutations in the ileal apical sodium-dependent bile acid transporter (ASBT; SLC10A2) can cause primary bile acid malabsorption but do not appear to account for most familial cases. Another major transporter involved in the intestinal reclamation of bile acids is the heteromeric organic solute transporter alpha-beta (OSTα-OSTβ; SLC51A-SLC51B), which exports bile acid across the basolateral membrane.

Fanconi-Bickel syndrome in two Palestinian children: marked phenotypic variability with identical mutation.

Background: Fanconi-Bickel syndrome (FBS, OMIM 227810) is a rare autosomal recessive disease caused by a deficiency of glucose transporter 2 (GLUT2), a member of the facilitative glucose transporter family (Santer et al. J Inherit Metab Dis 21:191-194, 1998). The typical clinical picture is characterized by hepatorenal glycogen accumulation resulting in hepato- and nephromegaly, impaired utilization of glucose and galactose, proximal renal tubular dysfunction, rickets and severe short stature.

Calprotectin in cystic fibrosis.

Background: There is increasing evidence that intestinal inflammation plays a major role in gastrointestinal symptoms in cystic fibrosis (CF). Fecal calprotectin is a marker that is elevated in several gastrointestinal inflammatory diseases, but little is known about its value in CF. We aimed to look for associations of elevated fecal calprotectin among CF patients and whether its level correlates with the clinical manifestations of CF.

Subjective global nutritional assessment in critically ill children.

Background: Underweight children admitted to the pediatric intensive care unit (PICU) have a higher risk of mortality than normal-weight children. The authors hypothesized that subjective global nutrition assessment (SGNA) could identify malnutrition in the PICU and predict nutrition-associated morbidities.

Methods: The authors prospectively evaluated the nutrition status of 150 children (aged 31 days to 5 years) admitted to the PICU with the use of SGNA and commonly used objective anthropometric and laboratory measurements.

Endoscopic diagnosis of pediatric acute gastrointestinal graft-versus-host disease.

Background And Objectives: Acute graft-versus-host disease (GVHD) is a major cause of morbidity and mortality in the first 100 days following allogeneic hematopoietic progenitor stem cell transplant. The best diagnostic endoscopic strategy for gastrointestinal (GI) GVHD is a matter of debate. Our aim in the present study was to compare the relative contribution of the endoscopic appearance and biopsies from upper endoscopy and flexible sigmoidoscopy in children with suspected acute GVHD.

One-day bowel preparation with polyethylene glycol 3350: an effective regimen for colonoscopy in children.

Background: Polyethylene glycol (PEG) 3350 is commonly used and has been proven safe and effective for the treatment of chronic constipation and as a 4-day bowel preparation in children. A 1-day PEG 3350 bowel preparation regimen has been recently developed for adults; however, data regarding its use in children are lacking.

Objective: To evaluate the safety and effectiveness of a 1-day PEG 3350 regimen for bowel preparation in children before colonoscopy.

H syndrome: recently defined genodermatosis with distinct histologic features. A morphological, histochemical, immunohistochemical, and ultrastructural study of 10 cases.

This study analyzes the histopathological findings in H syndrome, a recently recognized autosomal recessive genodermatosis characterized by indurated, hyperpigmented, and hypertrichotic skin in well-defined anatomical areas accompanied by various systemic manifestations. So far, descriptions of the histopathological skin changes in this disorder, as reported in a few small case series, were inconsistent, leading to diverse clinical interpretations. In an attempt to define standardized, diagnostic, morphological criteria that will distinguish this disorder from other fibrosing conditions, we studied skin biopsies from 10 patients with H syndrome.

Tricho-hepato-enteric syndrome: a case of hemochromatosis with intractable diarrhea, dysmorphic features, and hair abnormality.

We report on a female infant with congenital iron storage disease, facial dysmorphism, intractable diarrhea, and hair abnormalities. The intractable diarrhea failed to resolve despite total parenteral nutrition and complete bowel rest for more than 3 weeks. The patient also had elevated liver enzymes and failure to thrive.
