Stimulation of growth-hormone release with clonidine does not distinguish individual cases of idiopathic Parkinson's disease from those with striatonigral degeneration.

Multiple System Atrophy (MSA) and idiopathic Parkinson's disease (PD) can be difficult to distinguish. There is an ongoing debate about the diagnostic value of the growth-hormone response to clonidine (CGH-test) in PD and MSA. We investigated whether the CGH-test can identify individual patients in the early stages of PD (n = 21) and Striatonigral Degeneration (SND, n = 11), a particular variety of MSA.

Hereditary prothrombin deficiency presenting as intracranial haematoma in infancy.

Hereditary deficiency of prothrombin is a rare autosomal recessive bleeding disorder, with severe bleeding diathesis in homozygotes, but rarely resulting in intracranial haematoma. We describe two infants of consanguineous parents, presenting with acute subdural haematoma. Because such haematomas in infancy are highly indicative of trauma caused by child battering and because the socio-economic status of the family was unstable, there was a suspicion of child battering.

Effects of female sex steroids on Parkinson's disease in postmenopausal women.

There are conflicting reports about estrogen modulating the activity of nigrostriatal dopaminergic neurons. Furthermore, modulation may be influenced by progesterone levels. Therefore, the clinical effects of sex steroids on parkinsonian symptoms in postmenopausal women with Parkinson's disease (PD) were analyzed in the present study.

Q10 therapy in patients with idiopathic Parkinson's disease.

A 3-month open-label trial was performed to evaluate the efficacy of 200 mg Q10 daily in 10 patients with Parkinson's disease. Motor performance was assessed with UPDRS and motor tests. There was no significant effect on the clinical ratings.
