A patient with hydranencephaly and PEHO-like dysmorphic features.

Progressive encephalopathy with Edema, Hypsarrhythmia, and Optic atrophy (PEHO syndrome) is a rare recessive autosomal neurodegenerative condition essentially described in Finland. The term PEHO-like syndrome has been proposed for patients who share clinical features of PEHO syndrome but lack the cerebellar atrophy, one of its major diagnostic criteria. We describe a patient presenting with hypoxic-ischaemic encephalopathy and PEHO-like syndrome features.

A 22-year French experience with solid tumors in children with Down syndrome.

Malignant solid tumors have rarely been reported in children with Down syndrome (DS) and are not well known. The authors collected from 1980 to 2001 all cases of solid tumors observed in DS patients aged from birth to 19 years within the network of the Société Française d'Oncologie Pédiatrique (SFOP). Only 21 cases were observed, with a peculiar distribution: a lack of intracranial tumors and embryonal neoplasms combined with an overrepresentation of lymphomas and germ cell tumors. The treatment of solid tumors in DS is difficult, due to physical and psychological impairments, different pharmacogenetic profile, and associated malformations.

Isolated idiopathic chronic pancreatitis associated with a compound heterozygosity for two mutations of the CFTR gene.

We report the case of a patient suffering from idiopathic chronic pancreatitis (ICP) and compound heterozygous for mutations G542X and S1235R of the cystic fibrosis transmembrane regulator (CFTR) gene. The patient had normal sweat test and no other clinical sign usually linked with a typical or moderate pathology (bronchiectasis, nasal polyposis, congenital absence of the vas deferens) of the CFTR gene. G542X is a severe mutation, which is usually found in classical cystic fibrosis when associated with other severe mutations. S1235R is a quite rare abnormality recently reported as being potentially pathogenic when combined in trans with a second CF mutation. Our case is quite similar to the only other six patients in the literature in whom only the pancreas is affected and who bear a rare mutation with moderate effect. The history and the clinical features of our patient indicate an unambiguous isolated ICP in which the presence of the S1235R mutation--in trans with regard to G542X--is likely responsible for the ICP phenotype. This case could throw light on some of the as yet poorly known abnormalities of the CFTR gene in the ICP phenotype.
