Classical Lemierre syndrome is a rare and severe disease with thrombosis of the internal jugular vein and metastatic infections. We report on a case of Lemierre-like syndrome secondary to mastoiditis, with a favorable outcome, in a healthy infant presenting with torticollis. Early diagnosis and treatment with antibiotics are necessary to decrease mortality. © 2015 Elsevier Masson SAS.

Dentoleukoencephalopathies with autosomal recessive inheritance are very rare. Recently, a large inbred Syrian pedigree was reported with oligodontia in association with a degenerative neurologic condition characterized by progressive ataxia and pyramidal syndrome and abnormalities in the white matter and cortical atrophy. A whole-genome screening of this family using 382 microsatellite markers was completed, but no evidence was found of linkage to any chromosomal region. A genome-wide linkage analysis using the 260K single nucleotide polymorphism Affymetrix array was then undertaken and a maximum multipoint logarithm of the odds score of 5.66 (NPL score∈=∈7.65) was detected on chromosome 10q22 region. This genomic interval contains 95 known genes including the Prosaposin gene (PSAP) responsible for metachromatic leukodystrophy, which was excluded. Seventeen additional candidate genes were tested and excluded. Sequencing of the whole candidate locus is in progress and should allow the identification of the causative gene in this rare disease, thereby improving the understanding of the physiopathology of this disease. © 2010 Springer-Verlag.

We report on two sibs with an elongated face with reduced expression, microcephaly, strabismus, wide philtrum, mild joint laxity, thumbsign, bilateral foot drop, and fixed pes cavus, absent tendinous reflexes, an unsteady gait, quick fatigue, slightly diminished limb muscle strength more pronounced distally, abnormalities of cranial nerves III, IV, VII, and most probably VI, and slowness in ideation. Previously unknown findings referred to as the "fork sign" at the pontine level and the "bracket sign" at the mesencephalic level were documented by magnetic resonance imaging. Differential diagnoses and the possibility of a hitherto unreported syndrome are discussed. © 2010 Wiley-Liss, Inc.

LGMD (limb-girdle muscular dystrophy) and CMD (congenital muscular dystrophy) are two common forms of neuromuscular disorders which are distinguishable by their age of onset but with probably a similar underlying pathway. In the present study, we report immunohistochemical, Western-blot and genetic analyses in a large consanguineous Tunisian family with two branches, including seven patients sharing similar LGMD2 phenotype in one branch and one CMD patient in the other branch. Linkage analyses were compatible with the LGMD2A locus in one branch and the MDC1A (muscular dystrophy congenital type 1A) locus in the other branch. This result was supported by deficiency in merosin and calpain3 in the CMD patient and LGMD patients respectively. Mutation analysis revealed two distinct mutations: a c.8005delT frameshift deletion in exon 56 of the LAMA2 (laminin-α2) gene (MDC1A) was found in the CMD patient and a new homozygous mutation C.1536+1G>T in the donor splice site of intron 12 of the CAPN3 (calpain3) gene (LGMD2A) was found in the LGMD patients. RT-PCR (reverse transcription-PCR) performed on total RNA from a LGMD2A patient's muscle biopsy showed complete retention of intron 12 in CAPN3 cDNA, generating a PTC (premature termination codon) that potentially elicits degradation of the nonsense mRNA by NMD (nonsense-mediated mRNA decay). Our results indicate that mRNA analysis is necessary to clarify the primary effect of genomic mutations on splicing efficiency that alters mRNA processing and expression level. ©The Authors Journal compilation ©2011 Biochemical Society.

We detected an unusual increase in congenital cerebral malformations and dysfunction in fetuses and newborns in French Polynesia, following an epidemic of Zika virus (ZIKV), from October 2013 to March 2014. A retrospective review identified 19 cases, including eight with major brain lesions and severe microcephaly, six with severe cerebral lesions without microcephaly and five with brainstem dysfunction without visible malformations. Imaging revealed profound neurological lesions (septal and callosal disruption, ventriculomegaly, abnormal neuronal migration, cerebellar hypoplasia, occipital pseudocysts, brain calcifications). Amniotic fluid was drawn from seven cases at gestation weeks 20 to 29. ZIKV RNA was detected by RT-PCR and infectious ZIKV isolates were obtained in four of five microcephalic, but not in two non-microcephalic cases with severe brain lesions. Medical termination of pregnancy was performed in eleven cases; two cases with brainstem dysfunction died in the first months of life; six cases are alive, with severe neurological impairment. The results show that four of seven tested fetuses with major neurological injuries were infected with ZIKV in utero. For other non-microcephalic, congenital abnormalities we were not able to prove or exclude ZIKV infection retrospectively. The unusual occurrence of brain malformations or dysfunction without microcephaly following a ZIKV outbreak needs further studies. © 2016, European Centre for Disease Prevention and Control (ECDC).
