We report here an autopsy case, an 8-year-old boy diagnosed as having infantile striatal necrosis, characterized by a preceding febrile illness followed by acute
encephalopathy
with abrupt obtundation, seizures and dystonia, with remarkable improvement of the disturbed consciousness and intelligence after
TRH
-T therapy. These clinical symptoms were linked with bilateral necrosis of the striata on CT scanning. The presented case belonged to a newly described subgroup of the heredogenous disorders that produce necrosis of the putamina in children.

In order to investigate whether the variations in prolactin (PRL) secretion found in patients with liver cirrhosis are related to the derangement of neurotransmitter metabolism, serum PRL levels were measured in 8 patients with hepatic encephalopathy (a condition where neurotransmission is severely deranged), in 10 patients with liver cirrhosis but without
encephalopathy
and in 10 control subjects under control conditions and in response to nomifensine, levodopa and synthetic
TRH
administration. Inhibition of endogenous catecholamine reuptake by nomifensine was able to significantly reduce PRL levels in normal subjects and in patients with liver cirrhosis, whereas only one out of 8 patients with hepatic encephalopathy showed a reduction in PRL levels. On the contrary, levodopa administration was able to reduce PRL secretion in all the subjects studied. PRL release by
TRH
was greater in patients with liver disease than in controls. The results seem to indicate that the derangement in neurotransmitter metabolism which occurs in liver cirrhosis is one, but not the sole cause of alterations of PRL secretion in liver cirrhosis. The failure of nomifensine to depress PRL is an early finding in the course of
encephalopathy
and may be of diagnostic value.

Elevated plasma concentrations and abnormal secretory patterns of GH have been found in patients with cirrhosis of the liver. Displacement of brain dopaminergic monoamines by false "neurotransmitters' produced in the gut has been postulated as a cause of
encephalopathy
. In this study basal GH plasma levels and their response to
TRH
and L-DOPA were determined in thirty-nine cirrhotic patients and fifteen controls. Eleven patients had evidence of
encephalopathy
(Group 1), twenty-eight did not (Group 2). Both basal levels and the mean peak response to
TRH
were significantly higher in the cirrhotic patients that in the controls (Group 3). Peak values were moderately, but not significantly, higher in Group 1 than in Group 2. The response to L-DOPA was considerably lower in the encephalopathic patients in comparison with the subjects of both Group 2 and Group 3. This finding is consistent with depletion of active "neurotransmitters' in CNS. Our data fail to demonstrate clearly whether the paradoxical response to
TRH
can also be related to these abnormalities of monoamine metabolism in cirrhotics.
