Carrier detection by microsatellite analysis of Duchenne/Becker muscular dystrophy in Hungarian families

Duchenne and Becker muscular dystrophies are among the most severe and frequent inherited disorders. Being still incurable, medical treatment is concentrated on the carrier diagnosis of the members of the affected families. Here we report the results of the studies of 151 members of 41 Hungarian families, obtained with multiplex PCR amplification of 18 exons as well as the muscle specific promoter region, and haplotype analysis of two polymorphic (CA)_n repeat microsatellite loci in introns 45 and 49 of the dystrophin gene. The analysis of 15 deletion-type families revealed a frequency of new mutations not differing significantly from that in the other regions of Europe. We also compared the allele distributions of the two microsatellites in randomly selected normal individuals and affected family members. The allele distribution of STRP45 shows interesting differences between the two populations.     

Local hyperthermia of the prostate gland for the treatment of benign prostatic hypertrophy and urinary retention.

Local hyperthermia of the prostate was used to treat 72 patients who had an indwelling catheter because of urinary retention caused by benign prostatic hypertrophy. One month after completion of treatment 50% of patients were able to dispense with the catheter and 1 year later 40% remained catheter-free. The best results were achieved in patients who underwent 6 to 10 treatment sessions in conjunction with cyproterone acetate 50 mg tid administered during the treatment period only.     

Survey of certification practices for patients admitted to Sterkfontein Hospital

The involuntary hospitalisation of psychiatric patients continues to be a controversial issue. All patients certified and admitted to Sterkfontein Hospital under Sections 9 and 12 of the Mental Health Act, No. 18 of 1973, over a 4-week period were surveyed. Almost 40% were admitted as urgent certifications. The majority of the patients in the sample were black, single, urban and had either primary or limited high school education. Most patients had been referred from academic/teaching and provincial hospitals. The average duration of hospital stay was 7.2 weeks, with only 1 patient eventually being transferred to a ward for chronic patients within the hospital, which suggests that Sterkfontein Hospital functions largely as an acute psychiatric facility. There was a discrepancy of approximately 30% between the assessments of the certifying and ward doctors, probably as a result of differing uses of terminology. Not only are more community psychiatric services needed, but communication between psychiatry and the other medical disciplines should be improved.     

Comparison of antigen expression on normal urothelial cells in tissue section and tissue culture

Antigenic characterization of urothelial cells cultured from normal adult ureter was performed. These cells were cultured using a simplified isolation and culture technique and a commercially available serum-free medium. The cells growing in these cultures had epithelioid morphology and normal quantities of DNA. The antigen expression on these cultured normal urothelial cells was evaluated using a panel of monoclonal antibodies: 5G6.4, AN43, URO-5, anti-keratin and anti-blood group antibodies, and 425 (anti-epidermal growth factor receptor). Lower levels of anti-A and AN43 binding on cultured cells were observed than are seen on urothelial cells in sections of normal ureter, while the binding of anti-blood group H, 5G6.4, and URO-5 was unchanged. Binding of anti-epidermal growth factor receptor antibody 425 was improved if the cells were grown in medium lacking epidermal growth factor. These results confirm the urothelial origin of these cultured urothelial cells but indicate that some antigenic differences between cultured normal urothelial cells and urothelial cells in situ in the normal ureter exist.     

The effect of bone drilling on pain in gonarthrosis

Summary Seventy-seven patients with mild to moderate gonarthrosis of the knee were treated by subchondral bone drilling, and followed for from 2 to 7 years. Patients with generalised arthrosis benefited more than those with unicompartmental involvement. Pain, assessed by a visual analogue scale, was significantly reduced compared with a control group of 16 patients who had a diagnostic arthroscopy only. Drilling is a safe procedure with few complications and can be used in patients when more extensive surgery is not yet indicated or possible.

Résumé Vingt-sept cas d'arthrose légère ou modérée du genou, diagnostiqués par arthroscopie et traités par forage, ont été revus avec un recul moyen de 4 ans (de 2 à 7 ans). La douleur, évaluée selon la cotation VAS, était diminuée pendant 24 mois en moyenne (1 à 76) dans les deux tiers des cas. Les résultats étaient meilleurs chez les patients présentant une arthrose globale que chez ceux atteints d'une arthrose uni-compartimentale. Ils étaient obtenus aussi bien dans les cas douloureux au repos (n=39) que dans ceux douloureux lors de la mobilisation du genou (n=14). Les complications ont été exceptionnelles (n=1). La douleur était diminuée dans une proportion significativement supérieure dans les genoux traités par forage que dans un groupe de contrôle de 16 cas, n'ayant subi qu'une arthroscopie à visée diagnostique (p=0.006). Le forage est un procédé sûr, n'entraînant que de rares complications. Il est indiqué dans le traitement des douleurs du genou chez les patients ayant une arthrose légère ou modérée, lorsque des interventions plus importantes ne sont ni nécessaires, ni réalisables.
