This is the clinical history of a term baby born at home who presents a severe hyperbilirubinémia. The medical monitoring was assessed by a private midwife according to parental choice. On the third day of life, the newborn presented an icterus and was exposed to natural daylight in the familial greenhouse under the midwife recommandations. On that day, no laboratory test precised the bilirubin level. On the fifth day, a blood sampling revealed a very high blood bilirubinémia (31 mg/dl or 527 mmol/L), the baby is refered to our NICU and underwent an exchange transfusion. The radiological assessment report structural abnomalies in basal ganglia seen on both MRI and transfontannellar echography. These lesions are known to be responsible of cerebral palsy and hearing loos. The neurophysiologic investigations showed background abnormaly and depression. The extensive blood sampling excluded haemolysis. The clinical examination brought out neurologic impairement and weight loos in this exclusively breastfed baby. This clinical case point out the increasing risk of home Kernicterius as hospital stays diminish and homebirth enthousiasm rise up. The present clinical situation vouches for an adaptation of care giving to both mother and child at home in order to avoid this severe illness.

The application of cross-point switch arrays as input selector switch devices for multi-channel electrophysiological experiments.

Integrated circuits (ICs) containing cross-point switch arrays were applied to create analog input selector switch devices for multi-channel electrophysiological experiments. The described analog input selector switch devices make it possible to connect to the main amplifier's inputs those microelectrode and preamplifier output wires that yield unit discharges of acceptable shape and amplitude, or yield other kind of acceptable electrophysiological signals (EEG, EP). This kind of selector allows to use higher number of preamplifier channels and to ignore the input channels without adequate signals or the channels with noisy inputs. No manual switching is required, as the work is done by computer controlled switches. The switch positions can be saved and reloaded at the next experimental session through an I/O port (e.g. the parallel port) of the computer.
