[Rapunzel syndrome in a child with trisomy 21: a case report].

Trichobezoard is a rare condition characterized by a gastric mass composed of hair or fibers due to a compulsive attitude (trichotillomania) and an eating disorder (trichophagia). Gastric trichobezoar is the most common form and may extend into the small bowel, sometimes reaching the last ileal loop, or even the transverse colon, resulting in Rapunzel syndrome. We here report a case of gastroduodenal and small intestine trichoboozoar in a 6-year-old girl with facies of trisomy, presenting with recurrent abdominal pain lasting for one months and suspected gastrointestinal lymphoma.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency in girls: a diagnosis not to be missed (a case report).

Glucose-6-phosphate dehydrogenase (G6PD) is a polymorphic enzyme encoded by the X chromosome. It protects the cell against hydrogen peroxide-induced damage and ensures an oxidative balance profile within the cell. The disease is more frequent in males, and rare cases are described in girls.

Gut microbiota in preterm infants with gross blood in stools: A prospective, controlled study.

Objective: Gross blood in stools is a peculiar entity in preterm infants, but little is known about its etiology. As gut microbiota can be distorted in preterm infants, we aimed to evaluate the gut microbiota in infants with gross blood in stools.

Study Design: In a prospective, controlled, single-center study, we enrolled all infants born before 34 weeks of gestational age presenting gross blood in stools that was either completely isolated or associated with mild clinical symptoms or radiological signs.

Risk factors of mild rectal bleeding in very low birth weight infants: a case control study.

Background: Mild rectal bleeding (MRB) is a particular clinical entity different from necrotizing enterocolitis, which significantly influences neonatal care in preterm infants. We aimed to determine the risk factors and to evaluate prospectively the clinical course of MRB.

Methods: We consecutively included in a case-control study all infants with birth weight ≤ 1500 g or gestational age ≤ 32 weeks admitted to our unit, and presenting MRB, defined as either isolated or associated with mild clinical or radiological signs.
