A 43-year-old man who presented parkinsonism due to pontine and extrapontine myelinolysis was reported. Late in February, 1990, the patient presented suffered from a flu-like illness and was seen at a community hospital. Physical finding showed the pigmentation on the whole body and hypotension, and laboratory examination revealed severe electrolyte imbalance (serum sodium 100 mEq/l, serum potassium 6.9 mEq/l, serum chloride 68 mEq/l) and hypoglycemia (postprandial serum glucose 78 mg/dl). Given these results, adrenal failure was strongly suspected. Prompt correction of electrocyte imbalance was performed by the infusion of sodium chloride, and four days later the serum sodium level reached 131 mEq/l. On the other hand, the patient was noticed lethargic and showed parkinsonism i.e., rest tremor, cog-wheel rigidity, and hypokinesia. Fourteen days after the onset of neurological abnormalities, the patient was referred to our hospital for further evaluation of parkinsonism. Additionally, neurological examination revealed dysphagia, mutism and positive pyramidal tract sign. On admission brain computed tomography was unremarkable, but on the 14th hospital day it showed low density area in the pons. Brain magnetic resonance imaging also showed a striking increase in T2-weighted signal from the pons, the midbrain, and the bilateral thalamus. Based on these findings, a diagnosis of parkinsonism due to pontine and extrapontine myelinolysis was made, and levodopa therapy was started. After the initiation of levodopa therapy, improvement of tremor, rigidity, and hypokinesia ensued with marked functional benefit, and the patient was discharged on the 49th hospital day. Levodopa was stopped three weeks after discharge but, all neurological abnormalities were not recurrent.(ABSTRACT TRUNCATED AT 250 WORDS)

Shaken baby syndrome is a serious form of physical child abuse, which is frequently overlooked. It should be suspected in all children younger than one year of age, who present with drowsiness, coma, seizures or apnoea. A combination of subdural haematomas and retinal haemorrhages with minimal or no trauma and no coagulopathy is almost pathognomonic of the syndrome. The findings are caused by shaking with or without impact. Physical signs of violence are often absent and the syndrome may easily be mistaken for serious infection or seizure disorder. Many cases are fatal or lead to severe disability including blindness, cerebral palsy, mental retardation or epilepsy in about 60% of the children. There are many unresolved problems regarding diagnosis, pathophysiology, treatment, prognosis, prophylaxis and legal actions. We discuss these problems and in addition present eleven children with shaken baby syndrome.

A 15-yr-old male patient with congenital adrenal hyperplasia (CAH) was referred to our department with a one year history of gradual worsening of tremors. He was diagnosed with salt-wasting 21-hydroxylase deficiency CAH at 40 d old and was started on hydrocortisone, fludrocortisone and salt. He was found to have hypertension at 8 yr of age. Detailed investigations failed to detect any cause for secondary hypertension. Physical findings on the current hospitalization objectified obesity, blood pressure of 150/80 mmHg, postural and action tremor, left cerebellar syndrome, reflex tetra pyramidal syndrome and mental decline. Brain magnetic resonance imaging (MRI) showed bilateral periventricular white matter hyperintensity that was more pronounced in the posterior regions and associated with cortico-subcortical atrophy and complete agenesis of the corpus callosum. All investigations for leukoencephalopathy were negative. A diagnosis of brain MRI abnormalities related to CAH was made, and the patient received symptomatic treatment of tremors. Our case report provides evidence of an increased frequency of brain MRI abnormalities in CAH. The literature suggests hormonal imbalance and exposure to excess exogenous glucocorticoids as main probable mechanisms. Thus, in clinical practice, CAH should be considered as one of the possible causes of brain white matter involvement associated with or without cerebral atrophy.
