Cryopreservation protocol for human biliary tree stem/progenitors, hepatic and pancreatic precursors.

Human biliary tree stem/progenitor cells (hBTSCs) are being used for cell therapies of patients with liver cirrhosis. A cryopreservation method was established to optimize sourcing of hBTSCs for these clinical programs and that comprises serum-free Kubota's Medium (KM) supplemented with 10% dimethyl sulfoxide (DMSO), 15% human serum albumin (HSA) and 0.1% hyaluronans.

Pfeiffer syndrome: literature review of prenatal sonographic findings and genetic diagnosis.

Purpose: Pfeiffer syndrome (PS) is an autosomal dominant disorder caused by mutations in FGFR1 and FGFR2 genes. Given its wide range of clinical expression and severity, early prenatal diagnosis is difficult and genetic counseling is desirable. We report a literature review of all prenatal diagnosis of PS and a case report, with a focused description of ultrasound findings.

Dandy-Walker Malformation: is the 'tail sign' the key sign?

Objective: The study aims to demonstrate the value of the 'tail sign' in the assessment of Dandy-Walker malformation.

Methods: A total of 31 fetal magnetic resonance imaging (MRI), performed before 24 weeks of gestation after second-line ultrasound examination between May 2013 and September 2014, were examined retrospectively. All MRI examinations were performed using a 1.

Prenatal diagnosis of proximal focal femoral deficiency: Literature review of prenatal sonographic findings.

Proximal focal femoral deficiency (PFFD) is a rare musculoskeletal malformation that occurs in 0.11-0.2 per 10,000 live births.

Role of magnetic resonance imaging in the prenatal diagnosis of gastrointestinal fetal anomalies.

Purpose: This study was done to evaluate the role of fetal magnetic resonance imaging (MRI) in the study of gastrointestinal malformations in comparison to prenatal ultrasound (US).

Materials And Methods: A prospective (2010-2012) study of 38 fetal MRI scans was performed on 38 fetuses between 24 and 38 weeks of gestation. All the fetuses had a US diagnosis of gastrointestinal anomalies.

Cholangiocarcinoma: increasing burden of classifications.

Cholangiocarcinoma (CCA) is a very heterogeneous cancer from any point of view, including epidemiology, risk factors, morphology, pathology, molecular pathology, modalities of growth and clinical features. Given this heterogeneity, a uniform classification respecting the epidemiologic, pathologic and clinical needs is currently lacking. In this manuscript we discussed the different proposed classifications of CCA in relation with recent advances in pathophysiology and biology of this cancer.

Second-trimester induced abortions in two tertiary centres in Rome.

Objective: Demand for second-trimester induced abortions (STIAs) increases in Italy. For these procedures, prostaglandins alone were used until 2010, when mifepristone became available. The present study compares the two modalities, and investigates the reasons for STIAs.

Bilateral subependymal heterotopia, ventriculomegaly and cerebellar asymmetry: fetal MRI findings of a rare association of brain anomalies.

Subependymal heterotopia (SEH) is a neuronal migration disorder characterized by nodules of gray matter along the lateral ventricular walls and often associated with other brain malformations. We present two cases of SEH associated with ventriculomegaly and cerebellar abnormalities diagnosed by fetal magnetic resonance imaging (MRI) at 20 and 23 weeks' gestation respectively. Fetal MRI findings of this association of abnormalities have never been reported in literature.
