Dandy-Walker Malformation (DWM) is a rare congenital malformation of the brain. It is characterized by cystic enlargement of the fourth ventricle which is communicating with an enlarged posterior fossa, cerebellar dysgenesis, high tentorial insertion and hydrocephalus. Neurocutaneous Melanosis (NCM) is a congenital neurocutaneous syndrome characterized by large or multiple melanocytic nevi and ...
Phacomatosis pigmentovascularis is a rare syndrome, defined as the simultaneous presence of vascular nevus and melanocytic nevus in the same patient. We report the case of a 53-year-old woman presented with dermal melanosis and extensive vascular nevus, which match the typical manifestations of phakomatosis pigmetovascularis of cesioflammea type, according to Happle's classification. The rare o...
This first comprehensive analysis of the global biogeography of marine protistan plankton with acquired phototrophy shows these mixotrophic organisms to be ubiquitous and abundant; however, their biogeography differs markedly between different functional groups. These mixotrophs, lacking a constitutive capacity for photosynthesis (i.e. non-constitutive mixotrophs, NCMs), acquire their phototrop...
During the 2003-2006 period, subjective health status in Chinese rural areas improved. We used a unique household longitudinal survey to analyze how the introduction of a public insurance system has contributed to the change. This program is based on a doubly voluntary process: counties decide to launch, then households decide to subscribe. We disentangle two channels of influence of the insura...
Neurocutaneous melanosis (NCM) is a rare, congenital non-hereditary syndrome, characterized by multiple pigmented nevi. We report the radiologic findings of a newborn who had extensive cutaneous melanotic nevus with satellite lesions in the brain. Ultrasound showed multiple echogenic foci in the cerebral parenchyma. Subsequent MRI confirmed these lesions as characteristic deposits of melanin. T...
