A favorable response to antiparkinsonian treatment in juvenile neuronal ceroid lipofuscinosis

To study the effect of dopaminergic drugs on the parkinsonism in juvenile neuronal ceroid lipofuscinosis, the authors conducted an open study of 21 patients. According to the motor Unified PD Rating Scale (UPDRS) score, treatment was initiated with either levodopa (n = 10) or selegiline (n = 6). Five patients served as a control group. The UPDRS score after 1 year was compared with the score at onset. Both in the control group and in the selegiline group, the mean UPDRS score increased, whereas in the levodopa group, the mean UPDRS score decreased. The difference between the levodopa group and the control group was significant.     

Sex differences in extrastriatal dopamine d(2)-like receptors in the human brain

OBJECTIVE: The study examined gender differences in extrastriatal dopamine D2-like receptor levels in the human brain in vivo. METHOD: [(11)C]FLB 457, a high-affinity radioligand for extrastriatal D(2)-like receptors, and a three-dimensional positron emission tomography system were used to measure D(2)-like receptor binding potentials in frontal cortex, temporal cortex, and thalamus in 12 healthy men and 12 healthy women. RESULTS: Women had higher D(2)-like receptor binding potentials than men in the three brain regions studied, and the difference in the frontal cortex was statistically significant. In a more detailed regional analysis, the difference between the sexes was most pronounced for the left and right anterior cingulate cortex. CONCLUSIONS: This study provides in vivo evidence for a gender difference in dopamine D(2)-like receptor levels, which could be reflected in gender-associated differences in clinical disorders linked to the dopamine system.     

Aetiology of chronic suppurative lung disease

Forty one (1%) of 4000 children referred for respiratory disease had chronic suppurative lung disease not due to cystic fibrosis. Further investigations showed congenital malformations in six (15%), primary ciliary dyskinesia syndrome in seven (17%), 11 had immunological abnormalities (27%), and two bronchiectasis due to aspiration (5%). Therefore the underlying cause for the disease was found in 63%. Identification of predisposing causes may facilitate prevention of further bronchial damage.     

Improving communication: a practical programme for teaching trainees about communication issues in the general practice consultation

This paper describes a teaching programme, for use in general practice vocational training, which provides a theoretical and practical framework for exploring key aspects of the consultation with trainees. A particular emphasis is on the educational or 'cognitive' outcomes of the consultation and skills for improving them. The five stages of the programme are described and an example of experience of each stage is given. The paper concludes with an evaluation of the programme by the trainers, trainees and social scientist involved.     

Levodopa alone and in combination with a peripheral decarboxylase inhibitor benserazide (madopar®) in the treatment of Parkinson's disease

Summary A combination of levodopa and the extracerebrally acting decarboxylase inhibitor benserazide (ratio 4:1) (Madopar^®), was compared with levodopa alone in a controlled double-blind clinical multicenter trial on 94 patients with Parkinson's disease. During 4 months of therapy levodopa + benserazide proved superior to levodopa on several accounts. Nausea and vomiting occurred with statistically significant less severity and frequency. Clinical improvement expressed through improvement in Webster rating occurred sooner and was all together greater.The treatment schedules did not differ with regard to other side effects, in particular involuntary movements and reduction in supine blood pressure. Neither treatment seemed to influence liver function, renal function and hematological parameters.

Zusammenfassung Levodopa in Kombination mit dem extracerebral wirkenden Dekarboxylasehemmer Benserazid (Dosisverhältnis 4:1) (Madopar^®) wurde mit Levodopa allein in einer kontrollierten, doppelblinden, klinischen Multizenterprüfung an 94 Patienten mit Morbus Parkinson verglichen. Während der viermonatigen Therapie zeigte sich in mehreren Beziehungen Levodopa + Benserazid dem Levodopa überlegen. Übelkeit und Erbrechen waren statistisch signifikant weniger schwerwiegend und traten seltener auf. Klinische Besserung, ausgedrückt durch Reduktion im Webster Rating, trat schneller ein und war im großen und ganzen höher.Andere Nebenerscheinungen, insbesondere unwillkürliche Bewegungen und Reduktion des Blutdruckes im Liegen, verteilen sich gleich über die beiden Gruppen. Bestimmungen von sowohl Leberfunktion und Nierenfunktion als auch hämatologischen Parametern ergaben keine signifikanten Änderungen.

     

Herpes simplex virus subunit antibodies in patients with Parkinson's disease.

Serum IgG antibodies against herpes simplex virus (HSV) type 1 capsid, envelope, and excreted antigens in 52 patients with idiopathic Parkinson's disease, and in their age- and sex-matched controls, were assayed with a solid-phase radioimmunoassay. When compared with the controls, patients with Parkinson's disease were found to have a substantially increased antibody response against each of the HSV subunit antigens tested. The increased antibody response in patients with Parkinson's disease was not associated with the occurrence of recurrent HSV infections, since the difference in antibody levels was most evident when comparing patients without recurrent HSV infections with their respective control group. Consequently, the increased HSV antibody response in patient with Parkinson's disease might depend on some antigenic stimulation other than ordinary recurrent HSV infections, or alternatively, on the generally enhanced immunological reaction of the patients against HSV.
