Diagnosis of sickle-cell disease with a universal heteroduplex generator.

A new diagnostic technique, universal heteroduplex generator screening, has been developed to detect homozygosity and heterozygosity for sickle-cell disease. Since it is a polymerase chain reaction-based technique, it may be used to detect haemoglobin S and haemoglobin C genotypes in adults, neonates, or from coelocentesis during the first 10 weeks of pregnancy. beta-globin gene nucleotide sequences are amplified by the polymerase chain reaction, and are heteroduplexed with a beta-globulin universal heteroduplex generator. Haemoglobins S and C mutations are identified by characteristic polyacrylamide minigel banding patterns. The technique is simple and rapid to do, even by nonspecialist laboratories, and is applicable to large-scale screening for haemoglobin S and C mutations as well as prenatal diagnosis of sickle cell disease.

Prevalence and treatment of carpal tunnel syndrome in renal haemodialysis.

The purpose of this study was to investigate the prevalence and aetiology of carpal tunnel syndrome (CTS) and the effect of open carpal tunnel decompression (CTD) in a group of patients on renal haemodialysis. In 91 patients attending a Renal Unit who were assessed only by clinical means, the prevalence of CTS was 7.1%. CTS development was not significantly correlated with known risk factors, in particular duration of dialysis and presence of an artero-venous fistula on the symptomatic limb. CTD led to a mean symptom-free period of 12 years. In summary, CTS is a frequent and serious disease affecting renal dialysis patients, but its aetiology remains uncertain. Nevertheless, CTD is an effective and lasting treatment for this condition.
